Description

cooking appliance

The present invention relates to a cooking appliance, and more particularly, to a cooking appliance provided with a door for opening and closing a cooking chamber.

A cooking appliance is one of home appliances for cooking food and is installed in a kitchen space to cook food according to a user's intention. These cooking appliances can be classified in various ways according to the type of heat source or type used, and the type of fuel.

When cooking appliances are classified according to the shape of a space in which plants are placed, the cooking appliances may be classified into open type cooking appliances and closed type cooking appliances. Enclosed cooking appliances include ovens, microwave ovens, and the like. In addition, open type cooking appliances include a cooktop, a hob, a griddle, and the like.

An enclosed cooking appliance is a cooking appliance that shields a space where food is located. Such an enclosed cooking appliance may cook food by heating the shielded space.

Inside the closed type cooking appliance, a cooking chamber is provided. The cooking chamber is a space in which food is placed, and a space in which a cooking appliance is shielded while cooking food. Such a cooking chamber becomes a space in which food is actually cooked.

In the closed type cooking appliance, a door that selectively opens and closes a cooking chamber is rotatably provided. The door may be rotatably installed in the body by a door hinge provided between the door and the body having the cooking chamber therein. The door may selectively open and close the cooking chamber by rotating around a portion coupled to the main body through a door hinge.

A heat source may be provided to an inner space of the cooking chamber opened and closed by the door. The heat source is provided to heat the cooking chamber. As such a heat source, a gas burner or an electric heater may be used.

An electrical cabinet may be disposed above the cooking chamber. Electrical components required for the operation of the closed type cooking appliance may be provided in the electrical compartment. Such an electrical chamber is formed as a space separated from the cooking chamber.

A cooling fan may be provided inside the control room to cool the control room. The cooling fan may be provided in the form of a centrifugal fan such as a sirocco fan, and may be disposed biasedly at the rear of the control room.

The cooling fan sucks in air from the outside, introduces it into the inside of the control room, and forcibly discharges hot air inside the control room to the outside, thereby cooling the control room.

The body may include a cavity and a front panel. The cavity forms the skeleton of the main body, and a cooking chamber may be formed inside the cavity. The front panel may be disposed in front of the cavity to form the front surface of the main body.

The electrical compartment may be disposed above the cavity. Also, the front of the control room may be shielded by the front panel. For example, at least a portion of the front panel may protrude above the cavity, and an upper region of the front panel disposed above the cavity may shield the front of the control room.

An exhaust port may be provided on the front panel. The exhaust port may be formed to pass through the front panel in the front and rear directions. Such an exhaust port may form a passage through which air inside the control room is discharged to the outside on the front panel.

The exhaust port may be disposed in the front of the control room, that is, in the upper region of the front panel. And, on the front side of the exhaust port, a discharge passage may be formed. A control panel and a door may be disposed on a front side of the exhaust port, and a gap of a predetermined height may be formed between the control panel and the door disposed in the vertical direction. A discharge passage may be formed in a gap between the control panel and the door.

The exhaust port is exposed toward the discharge passage and may be connected to the discharge passage. In addition, at least a portion of the exhaust port may be exposed to the front of the cooking appliance through the exhaust passage. That is, at least a portion of the exhaust port may be exposed forward through a gap between the control panel and the door.

Air introduced into the control room by the cooling fan inside the control room may be discharged to the outside of the control room through an exhaust port. In addition, the air discharged through the exhaust port may be discharged toward the front of the cooking appliance through the discharge passage between the control panel and the door.

Meanwhile, heat inside the cooking chamber generated during the cooking process may be transferred to the outside of the door through the door. In order to shield such conduction heat, a plurality of glasses may be installed on the door.

For example, a front glass disposed on an outer surface of the door and a rear glass disposed on an inner surface of the door may be installed in the door, and a plurality of middle glasses may be installed between the front glass and the rear glass. Each intermediate glass may be provided with a radiant energy reflection coating for heat shielding.

Heat inside the cooking chamber is transferred to the inner surface of the door and then to the front glass through the middle glass inside the door. Conducted heat can be shielded by the radiant energy reflection coating of the inner glass.

In addition, a discharge hole may be provided at the top of the door. The discharge hole may be formed to pass through the top of the door in the vertical direction. Hot air inside the door may be discharged through the discharge hole. At the same time, cold air may be sucked into the lower part of the door into the door from which the hot air has escaped.

That is, the door can be cooled by an air flow in which hot air inside the door is discharged to the upper part of the door and cold air is introduced into the door through the lower part of the door.

As described above, the discharge hole is disposed at the top of the door. As such, the discharge hole disposed at the top of the door may be connected to the discharge passage. That is, the hot air discharged through the exhaust port and the hot air discharged through the discharge hole may merge in the discharge passage.

Hot air discharged from the inside of the control room through the exhaust port may pass through the exhaust passage, pass through an upper area of the exhaust hole, and then be exhausted to the outside of the cooking appliance. During this process, a phenomenon in which hot air flowing inside the discharge passage flows backward into the door through the discharge hole may occur.

That is, a phenomenon in which air discharged from the inside of the control room cannot escape to the outside of the cooking appliance and flows backward into the door through the discharge hole may occur. When such reverse flow occurs, cold air is not properly introduced into the door, and accordingly, it is difficult to smoothly cool the door.

In Prior Document 1 (Korean Patent Publication No. 10-2015-0030016), an oven is disclosed.

As shown in FIGS. 64 and 65, the oven 1 disclosed in Prior Document 1 includes a casing 10 in which a cooking chamber 20 is provided, and a door 30 that opens and closes an open front of the cooking chamber 20. can include

The cooking chamber 20 is a cooking space formed by the top plate 21, the bottom plate 22, both side plates 23 and the rear plate 24. Various components constituting the oven 1 may be incorporated in a space between the outside of the cooking chamber 20 and the casing 10 (hereinafter, referred to as a “battery chamber”). A control panel 12 for controlling the operation of the oven 1 may be installed at an upper end of the casing 10 .

A cooling fan 50 may be installed outside the top plate 21 . The cooling fan 50 may introduce outside air into the control room through at least one opening installed in the rear plate 11 of the casing 10, and then discharge the air introduced into the control room back to the outside. .

A cooling passage 55 may be provided inside the electrical compartment. The cooling passage 55 forms a passage through which air sucked by the cooling fan 50 flows toward the front surface of the oven 1 .

A cooling outlet 57 may be provided at a front side of the cooling passage 55 . The air that has passed through the cooling passage 55 may be discharged to the top of the door 30 through the cooling outlet 57 . The cooling outlet 57 may be located behind the door 30 .

A cooling guide 80 may be installed at the front end of the cooling outlet 57 . The cooling guide 80 may be provided in the form of a bent bracket to narrow the width of the cooling outlet 57 .

In the cooling outlet 57 whose width is narrowed by the cooling guide 80, a phenomenon in which the flow rate of air passing through the cooling outlet 57 increases may occur. Accordingly, the air passing through the cooling discharge port 57 is discharged to the outside of the oven 1 at a high speed, while the pressure of the cooling discharge port 57 is lowered so that the surrounding air gathers around the cooling discharge port 57. phenomena can occur.

In this way, the discharge of the air inside the door 30 to the top of the door 30 may be induced by the force of the air around the cooling discharge port 57 gathering to the top of the door 30 .

In Prior Document 1, the inflow of cold air into the door 30 is activated by the discharge induction of the air inside the door 30, and the air discharged through the cooling discharge port 57 inside the door 30. The effect that backflow into the furnace can be suppressed is suggested.

However, Prior Document 1 has the following problems.

According to Prior Document 1, the air passing through the cooling outlet 57 and the air discharged from the door 30 are discharged to a space located in front of the cooling outlet 57 and above the door 30.

That is, while the air discharged through the cooling outlet 57 and the air discharged from the inside of the door 30 are joined in one space, vortexes may be generated in the corresponding space. As the vortex is generated in this way, the air passing through the cooling outlet 57 and the air discharged from the door 30 may not be properly discharged to the outside of the oven 1, and the air in the space may not be properly discharged to the door 30. ) may cause reverse flow to the inside.

In this case, it is difficult to properly cool the inside of the control room and the inside of the door 30 .

Also, in Prior Document 1, the cooling guide 80 is also extended in the longitudinal direction along the lower part of the cooling outlet 57, and the cooling guide 80 is fixed to the lower portion of the cooling outlet 57.

If the cooling outlet 57 is formed in a form divided into a plurality of pieces along the width direction of the oven 1, a plurality of cooling guides 80 to be fixed to the lower portion of the cooling outlet 57 must also be provided.

In this case, a problem arises in that the number of assembly man-hours and parts required to install the cooling guide 80 increases.

In addition, if the cooling outlet 57 is provided continuously along the width direction of the oven 1, that is, if only one long cooling outlet 57 is formed in the oven 1, the strength of the front surface of the casing 1 corresponds to that. is bound to weaken.

On the other hand, when meat or meat-containing food is heated and cooked using the closed cooking appliance as described above, oil such as fat or oil from the food floats inside the cooking chamber and is attached to the wall of the cooking chamber. It contaminates the inner walls of the cooking chamber.

Oil adhered (adhered) to the wall surface of the cooking chamber in this way is so-called polymerized (polymerization (reaction)) and is firmly adhered, making it difficult to clean (remove).

Among cooking appliances that have recently been released, there is a self-cleaning function that automatically removes contaminants such as oil as described above.

The self-cleaning function of the cooking appliance is a function that automatically removes contaminants such as oil adhered (adhered) to the wall of the cooking chamber.

Self-cleaning in cooking equipment, when contaminants such as oil adhere to the walls of the cooking chamber, heats the inside of the cooking chamber with a heat source such as a burner or heater to maintain the temperature inside the cooking chamber at a high temperature for a long time, thereby burning and removing the contaminants It is mainly made in the form of using the so-called pyrolysis method called pyrolysis.

Prior Document 1 also discloses a pyrolytic cleaning function that is the same as or similar to this self-cleaning function. According to this, the control unit 38 of Prior Document 1 may perform a washing mode in which the temperature inside the cooking chamber 20 is raised to pyrolyze and remove foreign substances. At this time, the pyrolytic cleaning may be performed in a form of burning and removing contaminants by maintaining the internal temperature of the cooking chamber 20 at a high temperature for a long time using an electric heater 42 .

When the above pyrolytic cleaning is performed, the inside of the cooking chamber 20 is maintained at a very high temperature. Therefore, to prevent safety accidents, the door of the cooking appliance must be firmly closed while the self-cleaning operation is performed.

To this end, a door locking device may be provided in the oven 1 . The door locking device may be installed on the front of the oven 1 and may include a latch provided to be hooked to the door 30 and a driving unit for operating the latch.

The driving unit may include a motor, and the driving unit and the latch may be connected by a link structure. While the door 30 is required to remain closed, the latch remains engaged with the door 30 . When the door 30 no longer needs to be kept closed, the state in which the latch is caught on the door 30 may be released.

The latch is installed on the front of the oven 1, rotates forward and protrudes forward of the oven 1. The latch may protrude while rotating forward to be caught on the door 30 and rotate backward to separate from the door 30 .

A locking groove may be provided at an upper end of the door 30, and the latch is inserted into the locking groove from the top of the locking groove and caught on the door 30, and thus the door 30 may be locked by the door locking device.

The latch may be installed to be exposed on the front surface of the oven 1 so that the latch can protrude toward the front of the oven 1 when necessary. In addition, such a latch may be disposed above the door 30 so as to be able to enter and exit the locking groove provided at the top of the door 30 .

In Prior Art Document 1, when the latch is installed at the above position, the latch is moved to the front of the oven 1 even when the door 30 opens the cooking chamber 20 and even when the door 30 closes the cooking chamber 20. exposed to

That is, the latch disposed above the door 30 is exposed to the front of the oven 1 through the gap between the door 30 and the control panel, which may degrade the appearance of the oven 1.

According to this embodiment, the air guide 300 may be formed in a frame shape with a width longer than the length and thickness and a thickness smaller than the length and width.

The vertical length of the air guide 300, that is, the thickness, may be equal to or less than the vertical length of the front space (S). The air guide 300 may be accommodated inside the front space (S). In addition, the air discharged from the exhaust port 122 or the door exhaust port 152 flows forward in the front space (S) and can pass through the air guide 300, passing through the air guide 300 to the outside of the cooking appliance. can be emitted as

As described above, the air guide 300 disposed in the front space (S) may divide at least a portion of the front space (S) into an upper space and a lower space.

The lateral length, that is, the width, of the air guide 300 may be a length corresponding to the lateral length of the front space (S). For example, the width of the air guide 300 may correspond to at least one of the lateral length of the control panel 200 and the lateral length of the door 150 .

The air guide 300 is disposed in the front space (S), and may be disposed in an area biased towards the front of the front space (S). The air guide 300 may divide the front area of the front space S into an upper space and a lower space.

In addition, the air guide 300 may be disposed on the lower side of the control panel 200 and coupled with the control panel 200 . To this end, cover

protrusions

The cover protrusions 210 and 220 may be formed to protrude downward from the bottom of the control panel 200 . The air guide 300 may be coupled to the

cover protrusions

210 and 220 at a position spaced apart from the lower end of the control panel 200 . The air guide 300 may be disposed at the lower side of the control panel 200 in a form spaced apart from the control panel 200 by a predetermined distance.

According to this embodiment, the plurality of

cover protrusions

210 and 220 may be spaced apart at predetermined intervals in the lateral direction. In addition, the air guide 300 can be stably fixed to the lower side of the control panel 200 by being coupled with the plurality of

cover protrusions

That is, the guide body portion 310 may be formed to have a sufficient length required for engagement with the

cover protrusions

210 and 220 .

The extension part 320 may be disposed on both sides in the lateral direction of the guide body part 310 . This extension 320 may be formed to protrude in a lateral direction from the guide body 310 .

The extension part 320 is not a part coupled to the

cover protrusions

210 and 220. Therefore, the length of the extension part 320 can be set shorter than the length of the guide body part 310 .

Since the extension part 320 is formed in a form in which the length of the extension part 320 is shorter than the length of the guide body part 310, the overall size and weight of the air guide 300 may not be unnecessarily increased.

The extension part 320 may be disposed biased toward the front side on the air guide 300 . Preferably, the guide body portion 310 and the extension portion 320 may be connected in the lateral direction so that the front end portion of the extension portion 320 and the front end portion of the guide body portion 310 are disposed on the same line. .

That is, the extension part 320 formed in the above shape has the effect of maintaining the aesthetics of the air guide 300 seen from the front while avoiding interference with the protruding surface part 123, and the size and weight of the air guide 300 The effect of preventing this unnecessary increase can be provided together.

[Arrangement structure of air guide considering the front appearance of cooking equipment]

15 is a front view showing a part of the front of the cooking appliance in a state in which the air guide is excluded, and FIG. 16 is an enlarged view of a part of the front of the cooking appliance shown in FIG. 15 . 17 is a front view showing a part of the front of the cooking appliance according to the first embodiment of the present invention, and FIG. 18 is an enlarged view of a part of the front of the cooking appliance shown in FIG. 17 .

15 and 16, when the air guide is removed from the cooking appliance, various parts of the cooking appliance are provided through a gap between the control panel 200 and the door 150 (hereinafter, referred to as a "front gap"). Parts may be exposed to the front of the cooking appliance.

As an example, a portion of the front panel 120 may be exposed to the front of the cooking appliance through the front gap. Specifically, the plurality of exhaust vents 122 provided in the control panel 200 may be exposed to the front of the cooking appliance through the front gap. In addition, the partition walls 121 disposed between the exhaust ports 122 may also be exposed to the front of the cooking appliance through the front gap.

Along with this, a part disposed behind the exhaust port 122 among various electric components disposed in the electrical compartment 103 may be exposed to the front of the cooking appliance through the front gap.

In addition, at least a portion of the door locking device may be exposed to the front of the cooking appliance through the front gap. For example, most of the latch 140 may be exposed toward the front of the cooking appliance through the front gap. In addition, a portion of the latch driving unit 145 may be exposed to the front of the cooking appliance together with the latch 140 through the front gap.

When the above items are exposed to the front of the cooking appliance, they may adversely affect the front appearance of the cooking appliance. That is, the shapes formed on the front panel 120, such as the exhaust port 122 and the bulkhead 121, the structure having a complex shape, such as the latch 140, and the electrical components exposed through the exhaust port 122, affect the front aesthetics of the cooking appliance. can be a factor that harms

In order to reduce the effect they have on the front aesthetics of the cooking appliance, in this embodiment, as shown in FIGS. 15 and 16 , an air guide 300 may be provided in the cooking appliance.

The air guide 300 may be disposed in the front gap. The air guide 300 is disposed between the control panel 200 and the door 150, and is provided to cover parts of the front panel 120, the latch 140, and electrical components from the front.

The air guide 300 covers a part of the front gap between the control panel 200 and the door 150, and thus the front panel 120 and the latch 140 exposed to the front of the cooking appliance through the front gap. ), electrical components, etc. may be covered by the air guide 300.

As the thickness of the air guide 300 increases, the area covered by the air guide 300 may be expanded. As the area covered by the air guide 300 expands, the front aesthetics of the cooking appliance may improve, but it becomes difficult to exhaust the cooking appliance forward through the front space S (see FIG. 3).

Conversely, as the thickness of the air guide 300 decreases, the area covered by the air guide 300 may decrease. As the area covered by the air guide 300 decreases, the effect of improving the aesthetics of the front of the cooking appliance decreases, but instead, exhaust to the front of the cooking appliance through the front space S can be more smoothly performed.

Considering this point, it is preferable that the thickness of the air guide 300 is set to the thickest within a range that enables smooth exhaust to the front of the cooking appliance through the front space (S).

When the thickness of the air guide 300 is set such that these conditions are satisfied, the front aesthetics of the cooking appliance can be effectively improved while maintaining the exhaust efficiency through the front gap above a certain level.

According to this embodiment, a portion of the area exposed to the front of the cooking appliance through the front gap is covered by the air guide 300, so that the front aesthetics of the cooking appliance can be improved.

As an example, the air guide 300 is disposed in the front gap, and may be disposed in the center of the front gap in the vertical direction. That is, the air guide 300 is disposed between the door 150 that closes the cooking chamber and the control panel 200, and the vertical distance between the air guide 300 and the control panel 200 and the air guide 300 and the door 150 may be disposed at a position where the vertical distance between them is set to be the same (hereinafter, referred to as a "central position").

Accordingly, the air guide 300 can form a structure that covers the front gap at the center of the front gap in the vertical direction, that is, at the center position. The air guide 300 allows the upper region of the front gap and the lower region of the front gap to be symmetrical around the air guide 300, so that the front shape of the cooking appliance looks more stable. , Through this, it can contribute to improving the front aesthetics of the cooking appliance.

As described above, the air guide 300 may be coupled to the control panel 200 by

cover protrusions

210 and 220.

As an example, the

cover protrusions

210 and 220 may include an outer cover protrusion 210 .

The outer cover protrusion 210 may be provided in a form protruding downward from the lower end of the control panel 200 . The outer cover protrusion 210 may be coupled to the air guide 300 at the lower part of the control panel 200 . Due to the coupling between the outer cover protrusion 210 and the air guide 300, the air guide 300 is separated from the lower end of the control panel 200 by a predetermined distance and can be coupled to the control panel 200.

Preferably, when the outer cover protrusion 210 is coupled to the air guide 300, the air guide 300 may be disposed in a central position.

At least a portion of the outer cover protrusion 210 may be disposed at a position capable of covering at least a portion of the latch 140 from the front side. For example, the outer cover protrusion 210 protrudes from the lower end of the control panel 200 toward the lower side, and may protrude from the upper side of the latch 140 in the vertical direction.

At least a portion of the latch 140 is covered by the outer cover protrusion 210 arranged in this way. Accordingly, when viewed from the front, at least a portion of the latch 140 is hidden by the outer cover protrusion 210 and is not visible.

As an example, the outer cover protrusion 210 may be formed in a protruding form from the lower end of the control panel 200 to a central position. Also, the width of the outer cover protrusion 210 may be set equal to or greater than the width of the latch 140 . The outer cover protrusion 210 may cover the upper half of the latch 140 exposed through the front gap from the front. The lower half of the latch 140 may be exposed to the lower side of the air guide 300 .

According to this embodiment, the shape of the side of the latch 140 may be set to a substantially "L" shape. The latch 140 may be formed in a shape in which an upper end thereof protrudes forward. Accordingly, when viewed from the front, the upper half of the latch 140 has a more complex shape than the lower half of the latch 140 .

The outer cover protrusion 210 is formed to protrude from the control panel 200 by a length required to be coupled with the air guide 300, while protruding from the control panel 200 by a length required to cover the upper half of the latch 140. can be formed to

That is, the outer cover protrusion 210 only protrudes as long as it can cover the upper half of the latch 140 while fixing the air guide 300 to the central position, and does not protrude any longer.

If the outer cover protrusion 210 protrudes longer, the outer cover protrusion 210 may cover the latch 140 more, but the coupling structure between the outer cover protrusion 210 and the air guide 300 is complicated However, a problem may occur in which the combination itself becomes difficult. In addition, due to the unnecessarily protruding structure, a problem in that the aesthetics of the front surface of the cooking appliance may be deteriorated.

Considering this point, in the present embodiment, the outer cover protrusion 210 does not protrude unnecessarily long and protrudes as long as it can cover the upper half of the latch 140 while fixing the air guide 300 in the central position.

The outer cover protrusion 210 preferentially covers the upper half of the latch 140, which is a part that can greatly affect the front aesthetics of the cooking appliance, and also arranges the air guide 300 in a central position. However, it can contribute to effectively improving the appearance of the front of the cooking appliance.

As another example, the air guide 300 is disposed in the front gap, and may be disposed at a position more inclined downward from the center in the vertical direction of the front gap.

Considering that the user's eye level is higher than the height of the air guide 300 disposed between the door 150 and the control panel 200 in general, the air guide 300 should be placed at the above position so that the user can The guide 300 can be better identified.

In addition, the air guide 300 must be placed at a position where the air guide 300 can be seen from the outside of the cooking appliance, so that the aesthetics provided by the air guide 300 can be expressed more effectively.

That is, since the air guide 300 is disposed at a position more inclined downward from the center of the front gap in the vertical direction, it is possible to effectively form a sense of aesthetics.

In addition, when the air guide 300 is disposed at the above position, the length of the

cover protrusions

210 and 220, especially the outer cover protrusion 210, in the vertical direction is inevitably increased.

As such, when the length of the outer cover protrusion 200 is increased, the outer cover protrusion 210 covers the latch 140 and may cover a wider area than the upper half of the latch 140 . In this way, a larger portion of the latch 140 is covered by the outer cover protrusion 210, so that the front aesthetics of the cooking appliance can be improved more effectively.

Meanwhile, in this embodiment, the latch 140 is illustrated as being disposed on one side of the body 100 in the lateral direction. For example, in the cooking appliance, one latch 140 may be disposed at a position biased toward one side of the main body 100 in a lateral direction. At this time, the latch 140 may be disposed at a position more biased toward one lateral side of the main body 100 than the exhaust port 122 .

According to this embodiment, a pair of outer cover protrusions 210 may be disposed between the control panel 200 and the air guide 300 . The pair of outer cover protrusions 210 may be disposed symmetrically about the lateral center of the cooking chamber, that is, about the lateral center of the main body 100. Alternatively, it may be expressed that the pair of outer cover protrusions 210 are symmetrically arranged around the center of the control panel 200 in the lateral direction.

One of the pair of outer cover protrusions 210 may be disposed in front of the latch 140 to cover the upper half of the latch 140 from the front. The other one of the pair of outer cover protrusions 210 is not disposed in front of the latch 140 .

However, since the pair of outer cover protrusions 210 are symmetrically arranged as described above, the shapes of the

cover protrusions

210 and 220 and the air guide 300 exposed through the front gap can be seen in a more balanced manner.

The cover protrusions 210 and 220 may include an inner cover protrusion 220 .

The inner cover protrusion 220 may be provided in a form protruding downward from the lower end of the control panel 200 . The inner cover protrusion 220 may be coupled to the air guide 300 at the lower part of the control panel 200 . Due to the coupling between the inner cover protrusion 220 and the air guide 300, the air guide 300 is separated from the lower end of the control panel 200 by a predetermined distance and can be coupled to the control panel 200.

Preferably, when the inner cover protrusion 220 is coupled to the air guide 300, the air guide 300 may be disposed in a central position.

At least a portion of the inner cover protrusion 220 may be disposed at a position capable of covering at least a portion of the partition wall 121 from the front side. For example, the inner cover protrusion 220 protrudes from the lower end of the control panel 200 toward the lower side, and may protrude from the upper side of the partition wall 121 in the vertical direction.

At least a portion of the partition wall 121 is covered by the inner cover protrusion 220 arranged as described above. Accordingly, when viewed from the front, at least a portion of the partition wall 121 is hidden by the inner cover protrusion 220 and is not visible.

The inner cover protrusion 220 disposed as described above may be disposed between the pair of outer cover protrusions 210 . For example, among the plurality of

cover protrusions

210 and 220 arranged in the lateral direction, the outer cover protrusion 210 may be disposed at the outermost side in the lateral direction, and the inner cover protrusion 220 may be disposed between them.

By the inner cover protrusion 220 and the outer cover protrusion 210 provided in this way, the air guide 300 is combined with the

cover protrusions

210 and 220 at multiple points in the lateral direction and can be stably fixed to the lower portion of the control panel 200. can

That is, the inner cover protrusion 220 may contribute to stably fixing the air guide 300 by increasing a coupling point between the control panel 200 and the air guide 300 .

In addition, the inner cover protrusion 220 is disposed at a position capable of covering the partition wall 121 from the front, so that the number of vertical structures exposed through the front gap is not increased.

That is, the inner cover protrusion 220 may be disposed in a form in which the inner cover protrusion 220 covers the partition wall 121, which is a longitudinal structure that is exposed anyway through the front gap. As a result, it can be seen that the number of longitudinal structures exposed through the front gap is not increased.

Accordingly, it is possible to effectively prevent deterioration of the front aesthetics of the cooking appliance due to the longitudinal structure exposed through the front gap.

In addition, the inner cover protrusion 220 disposed as described above can be disposed at a position avoiding the exhaust port 122 . The exhaust port 122 forms a passage necessary for the air in the electrical compartment 250 (see FIG. 3) to be discharged to the front space S.

Air introduced into the electrical compartment 103 by the fan 260 (see FIG. 3 ) is heat-exchanged inside the electrical compartment 103 and can cool electrical components and the like. The air heat-exchanged inside the electrical compartment 103 may be discharged to the front space S through the exhaust port 122 in a high-temperature state.

Assuming that the inner cover protrusion 220 is formed of a plastic material, if the inner cover protrusion 220 is constantly exposed to high-temperature air discharged through the exhaust port 122, thermal deformation of the inner cover protrusion 220 occurs. risk of becoming may increase.

For example, if the inner cover protrusion 220 is disposed in front of the exhaust port 122 instead of in front of the partition wall 121, the hot air discharged through the exhaust port 122 causes thermal deformation of the inner cover protrusion 220. may occur.

Considering this point, in the present embodiment, the inner cover protrusion 220 is disposed at a position avoiding the exhaust port 122, that is, in front of the partition wall 121 instead of in front of the exhaust port 122.

As a result, thermal deformation of the inner cover protrusion 220 can be effectively prevented, and air discharge through the exhaust port 122 can be smoothly performed without being hindered by the inner cover protrusion 220 .

That is, the inner cover protrusion 220 of the present embodiment is disposed at a position to cover the exhaust port 122 from the front, so that there is a risk of thermal deformation of the inner cover protrusion 220 without interfering with the discharge of air through the exhaust port 122. It can be disposed at a position to lower the cooking appliance and at a position to improve the front aesthetics of the cooking appliance.

In summary, the effects provided by the air guide 300 arranged as described above and the

cover protrusions

210 and 220 for fixing it are as follows.

First, a part of the structures exposed through the front gap is covered by the air guide 300 that provides a structure that covers the front gap and crosses the front gap laterally, so that the front aesthetics of the cooking appliance can be improved.

The air guide 300 covers a part of other rear structures and at the same time focuses the eyes looking at the front gap to the air guide 300, so that an optical illusion effect as if only the air guide 300 exists in the front gap to be provided

In addition, the air guide 300 forms a structure that covers the front gap at the center of the front gap, so that the upper region of the front gap and the lower region of the front gap are symmetrical, and the front shape of the cooking appliance is more stable. can be made to look like

Through this, the air guide 300 can contribute to effectively improving the front aesthetics of the cooking appliance.

Second, since at least a portion of a large and complicated structure such as the latch 140 is covered by the outer cover protrusion 210, the front aesthetics of the cooking appliance can be more effectively improved.

According to this embodiment, the upper half of the latch 140, which is a part that can greatly affect the front aesthetics of the cooking appliance, can be covered by the outer cover protrusion 210 provided to fix the air guide 300. .

That is, the arrangement position of the outer cover protrusion 210 provided for fixing the air guide 300 is appropriately set to the front of the latch 140, thereby stably fixing the air guide 300 and improving the front aesthetics of the cooking appliance. it can be done

Third, the inner cover protrusion 220 is disposed at a position to cover the partition wall 121 partitioning between the exhaust port 122 and the exhaust port 122 from the front, so that the inner cover without interfering with the discharge of air through the exhaust port 122. An effect of reducing the risk of thermal deformation of the cover protrusion 220 and an effect of improving the front aesthetics of the cooking appliance may be provided together.

Referring to FIGS. 13 and 17 to 20 , the

cover protrusions

210 and 220 may be included in the front panel 120 . As an example, the

cover protrusions

210 and 220 may be integrally formed with the front panel 120 . More specifically, the

cover protrusions

210 and 220 may be integrally formed with the lower end of the front panel 120 .

In this embodiment, it is exemplified that the lower end of the front panel 120 and the

cover protrusions

210 and 220 are formed of a plastic material. Since the

cover protrusions

210 and 220 are made of a plastic material and integrally formed with the lower end of the front panel 120, the cost required for adding the

cover protrusions

210 and 220 can be reduced, and the

cover protrusions

210 and 220 are made of a metal material. The weight of the

cover protrusions

210 and 220 can be significantly reduced compared to the case where they are formed.

The air guide 300 may be formed of a metal material. As an example, the air guide 300 may be formed of a metal material having excellent heat resistance and a unique metallic luster. The air guide 300 is not easily deformed by high-temperature heat, is not easily damaged by impact, and can contribute to improving the aesthetics of the cooking appliance through its metallic luster.

Considering that the air guide 300 is placed in a path through which hot air is discharged, that it is placed in a conspicuous position in front of the cooking appliance, and that it is placed in a position where contact with the user can occur frequently , In this embodiment, the air guide 300 is formed of a metal material.

The cover protrusions 210 and 220 may be coupled to the guide body 310 . A hollow is formed in each of the

cover protrusions

210 and 220, and a fastening hole communicating with the guide body 310 may be formed to pass through in the vertical direction. The cover protrusions 210 and 220 and the guide body 310 may be coupled by a fastening member 301 such as a screw.

As another example, as shown in FIGS. 21 and 22 , the

cover protrusions

330 and 340 may be included in the air guide 300a. As an example, the

cover protrusions

330 and 340 may be integrally formed with the air guide 300a.

In this embodiment, a combination of the

cover protrusions

330 and 340 and the air guide 300a is illustrated as being formed of a metal material. As an example, the combination of the

cover protrusions

330 and 340 and the air guide 300 may be formed of a metal material having excellent heat resistance and a unique metallic luster.

In this way, since the

cover protrusions

330 and 340 are formed integrally with the air guide 300a with a metal material, the

cover protrusions

330 and 340 may not be easily deformed even in high temperature heat.

In addition, since both the

cover protrusions

330 and 340 and the air guide 300a, which occupy most of the structures exposed through the front gap, are formed of a metallic material having a metallic luster, the aesthetics of the cooking appliance can be more effectively improved.

[Arrangement structure of air guide considering exhaust flow]

23 is a cross-sectional view showing air flow inside the cooking appliance according to the first embodiment of the present invention, FIG. 24 is an enlarged view of a portion of the cooking appliance shown in FIG. 23, and FIG. 25 is an enlarged view of FIG. This is an enlarged view of a portion of the cooking appliance shown in .

Referring to FIGS. 23 to 26 , external air may flow into the electrical compartment 103 from the rear side of the cooking appliance by the operation of the fan module 170 . The air introduced into the control room 103 can move forward inside the control room 103 and cool the electric components inside the control room 103 .

More specifically, outside air may flow into the cooking appliance through the lower portion of the main body 100 . External air introduced through the lower part of the main body 100 passes through the space at the rear of the cooking appliance where the convection unit 160, etc. are disposed, and various parts disposed in the rear space of the cooking appliance, for example, the convection unit 160 ) can be cooled, such as a motor for driving.

As such, the air passing through the rear space of the cooking appliance and moving upward can move toward the control room 103 through the space covered by the control room cover 135 between the rear space of the cooking device and the control room 103. there is.

Air that has moved into the electrical compartment 103 may be sucked in by the fan module 170 and introduced into the cooling passage 105 . Air introduced into the cooling passage 105 may move forward inside the cooling passage 105 and cool electric components inside the electrical compartment 103 .

As described above, the air moved forward from the inside of the electrical compartment 103 may be discharged to the front of the electrical compartment 103, that is, to the front space S through the exhaust port 122.

In addition, the air inside the door 150 heated by the heat transferred from the cooking chamber 101 during the cooking process may be discharged to the outside of the door 150 through the door exhaust vent 152 provided at the top of the door 150.

As the hot air inside the door 150 is discharged, outside air from the lower front side of the cooking appliance may flow into the door 150 through the air flow hole provided at the lower part of the door 150 and rise. In this process, the heated door 150 may be cooled by the heat transferred from the cooking chamber 101 to the door 150 .

In addition, air that cools the door 150 and rises inside the door 150 may be discharged to the front space S through the door exhaust port 152 . That is, the air discharged through the exhaust port 122 and the air exhausted through the door exhaust port 152 may merge in the front space S and be discharged toward the front of the cooking appliance.

According to this embodiment, the front space (S) is a space surrounded by the door 150, the front panel 120, and the control panel 200, and the air guide 300 can be disposed in this front space (S). .

The exhaust port 122 may communicate with the front space S at the rear side of the front space S, and the door exhaust port 152 may communicate with the front space S at the lower side of the front space S. And, the front space (S) may be opened toward the front of the cooking appliance.

The door exhaust port 152 may be disposed between the air guide 300 and the front panel 120 . Specifically, the door exhaust port 152 may be disposed in front of the exhaust port 122 . That is, in the front-back direction, the door exhaust port 152 may be disposed between the air guide 300 and the exhaust port 122.

In addition, the door exhaust port 152 may be disposed below the air guide 300 and the exhaust port 122 . In addition, the door exhaust port 152 is provided at the top of the door 150 and may be provided on the second half 150b.

Accordingly, the door exhaust port 152 is disposed at a rearward biased position on the door 150, and may be disposed at a lower side than the top of the door 150 formed by the front half 150a.

Looking at the arrangement relationship between the exhaust vent 122, the door exhaust vent 152, and the air guide 300, the door exhaust vent 152 is disposed on the door 150 at a position that can be most adjacent to the exhaust vent 122 in the front-back direction. .

If the door exhaust port 152 is disposed in the front half portion 150a of the door 150 instead of the second half portion 150b, the hot air discharged through the exhaust port 122 flows into the door 150 through the door exhaust port 152. The likelihood of regurgitation increases.

The air discharged through the exhaust port 122 is gradually diffused in the front space (S) and moves forward in the front space (S). That is, the air discharged through the exhaust port 122 spreads not only in the left and right directions but also in the vertical direction and moves forward in the front space (S).

Therefore, the more the door exhaust port 152 is located at the front side in the front space S, the higher the possibility that the air exhausted through the exhaust port 122 flows into the door exhaust port 152. In this way, when the hot air discharged through the exhaust port 122 flows backward into the door 150 through the door exhaust port 152, the door 150 cannot be cooled smoothly and flows into the front space (S). It becomes difficult for the generated heat to be smoothly discharged to the outside of the cooking appliance.

Considering this point, in the present embodiment, the door exhaust port 152 is disposed in the second half 150b of the door 150, and thereby positioned at a position most adjacent to the exhaust port 122 on the door 150 in the front-back direction. A door exhaust port 152 may be disposed.

As a result, the door exhaust port 152 can be disposed at a position that can be maximally out of the flow area of the air discharged through the exhaust port 122 among selectable forward and backward positions within the door 150 .

Also, according to the present embodiment, the door exhaust port 152 is disposed in the second half portion 150b, so that it may be disposed at a lower portion of the door 150 formed by the first portion 150a rather than at the top. That is, the door exhaust port 152 may be disposed at a position farther downward from the flow area of the air discharged through the exhaust port 122 .

As a result, the door exhaust port 152 may be disposed at a position where it can deviate as far as possible from the flow area of the air discharged through the exhaust port 122 . The door exhaust port 152 disposed in this way may contribute to preventing the hot air discharged to the front space S from flowing backward into the door 150 .

In addition, the door exhaust port 152 may not be disposed below the air guide 300 in the vertical direction, but may be disposed rearward of the air guide 300. Accordingly, the flow of air discharged from the door exhaust port 152 can smoothly flow toward the front space S without being hindered by the air guide 300 .

According to this embodiment, the door exhaust port 152 may be disposed between the air guide 300 and the front panel 120. That is, the air guide 300 may be disposed in front of the exhaust port 122 and the door exhaust port 152. The air guide 300 may be disposed at a position biased towards the front side in the front space (S).

The air guide 300 arranged in this way can guide the flow of air discharged from the exhaust port 122 and the door exhaust port 152 to the front space S from the front side of the front space S.

For example, air discharged to the front space (S) from the exhaust port 122 and the door exhaust port 152 may be discharged to the front of the cooking appliance while converging in the front space (S). The air guide 300 may be disposed in a flow path of air discharged from the front space S to the front of the cooking appliance (hereinafter, referred to as an “exhaust passage”).

The air guide 300 arranged in this way may be provided in the form of a frame having a longer width than the length and thickness and a thin thickness compared to the length and width. In addition, the air guide 300 disposed at the central position of the front gap may be disposed at the center of the front space S in the vertical direction.

The air guide 300 may be disposed on the exhaust flow path to divide the exhaust flow path into upper and lower parts. Accordingly, the air introduced into the front space S through the exhaust port 122 and the door exhaust port 152 is branched up and down through the upper and lower exhaust passages and flows forward.

When the flow of air discharged from the exhaust port 122 and the flow of air discharged from the door exhaust port 152 converge in the front space (S), there is a possibility that a vortex is generated in the front space (S).

When a vortex is generated in the front space (S), the air introduced into the front space (S) is not properly discharged to the outside of the cooking appliance, or the air in the front space (S) is exhausted from the door through the door exhaust port (152). (150) A phenomenon of reverse flow to the inside may occur.

Considering this point, in this embodiment, the air guide 300 is disposed on the front side of the front space S, and the flow of air flowing through the exhaust passage is branched up and down by the air guide 300. do.

In this way, when the air flow diverged by the air guide 300 is formed in the front space (S), the possibility of vortex generation in the front space (S) can be significantly reduced.

That is, the air guide 300 disposed on the front side of the front space S in the front space S is disposed on the exhaust passage and diverges the flow of air flowing through the exhaust passage, so that the front space S It is possible to effectively suppress the generation of vortices within.

In addition, the inner cover protrusion 220 provided to fix the air guide 300 to the control panel 200 may be disposed between the exhaust vent 122 and the exhaust vent 122 .

The inner cover protrusion 220 disposed in this way covers the partition 121 from the front of the partition 121 so that it is not visible, and is disposed at a position that does not overlap with the exhaust port 122, so that the

cover projections

210 and 220 or the air guide ( 300) can effectively lower the passage resistance.

In addition, as described above, the front end 301 of the air guide 300 disposed on the front side of the front space S in the front space S has upper and lower contact with at least a portion of the windshield 153 of the door 150. It can be arranged at a position overlapping in the direction.

As an example, the front end 301 of the air guide 300 is disposed at the same position as the rear end of the windshield 152 in the front-back direction, or at a position more forward than the rear end of the windshield 152. can be placed.

In this way, since the air guide 300 is disposed at a position biased toward the front in the front space S, the flow of air flowing toward the front of the cooking appliance in the front space S is more reduced by the air guide 300. can be guided effectively.

In addition, since the air guide 300 is disposed at a position where the air guide 300 can be seen from the outside of the cooking appliance as described above, the aesthetics provided by the air guide 300 can be expressed more effectively.

Meanwhile, in the process of discharging hot air from the front space (S), some of the discharged air comes into contact with the lower end of the control panel 200, and as a result, condensed water may form on the lower end of the control panel 200.

As such, when the condensed water condensed at the lower end of the control panel 200 falls to the upper end of the door 150, the water that collides with the door 150 splashes around the door 150 and contaminates the surrounding area.

As described above, when the air guide 300 is disposed at a position biased forward in the front space S, the control panel 200 and the door do not allow condensed water formed on the lower part of the control panel 200 to fall on the door 150. (150) can be blocked between them.

Since the distance between the control panel 200 and the air guide 300 is much closer than the distance between the control panel 200 and the door 150, even if the condensate falls on the air guide 300, the amount of water splashing around it there won't be too many

That is, by the air guide 300 arranged in the above-described form, contamination around the cooking appliance due to condensate water can be remarkably reduced.

In addition, the rear end 303 of the air guide 300 may be disposed forward of the door exhaust port 152 in the front-back direction.

Accordingly, between the door exhaust port 152 and the air guide 300, a passage having a sufficient height for the air inside the door 150 to be discharged to the front space S through the door exhaust port 152 may be formed.

As a result, the air discharged from the door exhaust port 152 is sufficiently mixed with the air discharged from the exhaust port 112 in the front space S, and then can pass through the air guide 300 arrangement section.

In addition, when the rear end 300 of the air guide 300 is disposed in the above position, the air guide 300 does not become an obstacle disposed vertically above the door exhaust port 152. Due to the air guide 300, flow resistance around the door exhaust port 152 can be effectively reduced.

More specifically, the rear end 303 of the air guide 300 may be disposed forward than the rear end 150b of the door 150 in the front-back direction.

When the position of the rear end 303 of the air guide 300 is set in this way, there is a gap between the air guide 300 and the door exhaust port 152 necessary to smoothly flow the air discharged from the door exhaust port 152. Enough distance can be secured.

As another example, the front end 301 of the air guide 300 is disposed at a position coincident with at least one of the front end of the control panel 200 and the front end of the door 150 in the front-back direction. can

For example, when viewed from the side, the front end 301 of the air guide 300 and the lower front corner of the control panel 200 may be disposed on the same line. Also, when viewed from the side, the front end 301 of the air guide 300 and the front upper edge of the door 150 may be disposed on the same line.

As the air guide 300 is arranged in this way, the positions of the control panel 200, the air guide 300, and the door 150 are aligned, and the exterior of the cooking appliance can be seen in a more balanced way, thereby improving the aesthetics of the cooking appliance. This could be improved a bit more.

As such, the arrangement of the air guide 300 to improve the aesthetics of the cooking appliance is possible because the air guide 300 is biased toward the front side of the front space S within the front space S.

That is, the air guide 300 of the present embodiment is disposed biasedly on the front side of the front space S in the front space S, thereby suppressing vortex generation in the front space S and improving the aesthetics of the cooking appliance. It can provide an enhancing effect together.

The present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and those skilled in the art can make various modifications and equivalent other embodiments. will understand Therefore, the true technical protection scope of the present invention should be determined by the claims below.

The lateral length, that is, the width, of the air guide 400 may be a length corresponding to the lateral length of the front space (S). For example, the width of the air guide 400 may correspond to at least one of the lateral length of the control panel 200 and the lateral length of the door 150 .

The air guide 400 is disposed in the front space (S), and may be disposed in an area biased toward the front of the front space (S). In the air guide 400, the front area of the front space S may be partitioned into a plurality of flow passages arranged in the vertical direction.

For example, a separation space may be formed between the door 150 and the guide portion 400a, between the guide portion 400b and the control panel 200, and between two

adjacent guide portions

400a and 400b. Each separation space formed in this way may form a passage of air passing through the air guide 400, that is, a flow path.

Referring to FIGS. 32 to 35 , the

cover protrusions

210 and 220 may be included in the front panel 120 . As an example, the

cover protrusions

210 and 220 are formed of a plastic material. Since the

cover protrusions

210 and 220 can be reduced, and the

cover protrusions

210 and 220 are made of a metal material. The weight of the

cover protrusions

The air guide 400 may be formed of a metal material. As an example, the air guide 400 may be formed of a metal material having excellent heat resistance and a unique metallic luster. The air guide 400 is not easily deformed even at high temperatures, is not easily damaged even when impacted, and can contribute to improving the aesthetics of the cooking appliance through its metallic luster.

36 is a cross-sectional view showing air flow inside the cooking appliance according to the second embodiment of the present invention, FIG. 37 is an enlarged view of a portion of the cooking appliance shown in FIG. 36, and FIG. 38 is an enlarged view of FIG. This is an enlarged view of a portion of the cooking appliance shown in .

36 to 38, the air guide 400 guides the flow of air discharged from the exhaust port 122 and the door exhaust port 152 to the front space S from the front side of the front space S. can

For example, air discharged to the front space (S) from the exhaust port 122 and the door exhaust port 152 may be discharged to the front of the cooking appliance while converging in the front space (S). The air guide 400 may be disposed in a flow path of air discharged from the front space S to the front of the cooking appliance, that is, in the exhaust passage.

The air guide 400 arranged in this way may include a first guide part 400a and a second guide part 400b. Each of the

guide parts

400a and 400b may be provided in the form of a frame having a longer width than the length and thickness and a thin thickness compared to the length and width.

The air guide 400 including the first guide part 400a and the second guide part 400b as described above may be disposed on the exhaust passage and partition the exhaust passage into a plurality of flow passages. In this embodiment, the exhaust passage is illustrated as being partitioned into three passages S1, S2, and S3.

The exhaust passage includes a first passage S1 formed between the door 150 and the first guide part 400a and a second passage formed between the first guide part 400a and the second guide part 400b. (S2), and a third flow path (S3) formed between the second guide part (400b) and the control panel 200.

Accordingly, the air introduced into the front space (S) through the exhaust port 122 and the door exhaust port 152 is branched up and down through the passages S1, S2, and S3 partitioned as described above, and can flow forward.

Air discharged through the door exhaust port 152 (hereinafter, referred to as "first exhaust air") is mainly discharged through the first flow path S1 disposed at the lowermost side among the flow paths S1, S2, and S3. can be fluid

In addition, through the third flow path S3 disposed at the uppermost side among the flow paths S1, S2, and S3, the air discharged through the exhaust port 122 (hereinafter, referred to as "second exhaust air") is mainly can be fluid

Mixed air of the first exhaust air and the second exhaust air may flow through the second flow path S2 disposed between the first flow path S1 and the third flow path S3.

The first exhaust air and the second exhaust air are air in a high temperature state. Therefore, the first discharge air and the second discharge air show an upward flow while passing through the front space (S).

Accordingly, contact between the first exhaust air and the second exhaust air passing through the front space S and the control panel 200 disposed above the front space S may occur. Due to this contact, a phenomenon in which water vapor is condensed at the lower end of the control panel 200 may occur.

In addition, the first exhaust air discharged upward from the door exhaust port 152 further induces the flow of air passing through the front space S to the upper side. Accordingly, the contact amount of the high-temperature air passing through the front space S with the control panel 200 may be further increased.

When the amount of high-temperature air passing through the front space S increases in contact with the control panel 200, the amount of water condensed at the bottom of the control panel 200 excessively increases, and the air contained in the air The risk of water vapor penetrating into the inside of the control panel 200 and wetting the inside of the control panel 200 increases.

Considering this point, in this embodiment, the air guide 400 is disposed in the front space (S) formed between the door 150 and the control panel 200.

The air guide 400 arranged in this way is disposed on the exhaust passage and can partition the exhaust passage into a plurality of passages S1, S2, and S3 along the vertical direction. Such an air guide 400 can branch the flow of air passing through the front space S into a plurality of flows along the vertical direction.

For example, only a portion of the flow of air passing through the front space S may flow forward through the third passage S3. Since the control panel 200 is disposed on the upper side of the third flow path S3, only air passing through the third flow path S3 can come into contact with the control panel 200, and the first flow path S1 or the second flow path S3 Air passing through the second flow path S2 is difficult to contact with the control panel 200 .

That is, the air guide 400 of the present embodiment divides the flow of air passing through the front space S into a plurality of flows along the up and down direction, so that the high-temperature air passing through the front space S passes through the control panel 200. ) can reduce the amount of contact.

In addition, the air guide 400 disposed as described above may serve to block the upward flow of the first exhaust air by blocking the space between the door 150 and the control panel 200 .

The air guide 400 serving this role not only prevents contact of the high-temperature first discharged air to the control panel 200, but also prevents the first discharged air from passing through the front space (S). It can act to prevent the flow from being directed upward.

Despite the action of the air guide 400 as described above, condensed water may form on the bottom of the control panel 200 .

As described above, when the air guide 400 is disposed at a position biased forward in the front space S, the control panel 200 and the door do not allow condensate to fall on the door 150 at the bottom of the control panel 200. (150) can be blocked between them.

Since the distance between the control panel 200 and the air guide 400 is much closer than the distance between the control panel 200 and the door 150, even if the condensate falls on the air guide 400, the amount of water splashing around it there won't be too many

That is, by the air guide 400 disposed in the above-described form, contamination around the cooking appliance due to condensate water can be remarkably reduced.

Meanwhile, since the first exhaust air passes through a region different from that of the second exhaust air, the humidity and temperature of the first exhaust air may be different from those of the second exhaust air.

In this way, when two airs having different humidity and temperature are joined in the front space (S) and mixed excessively, a vortex may be generated in the front space (S).

Considering this point, in this embodiment, the air guide 400 is disposed on the front side of the front space (S), and the air guide 400 supplies the first discharge air and the second discharge air to the front space (S). It can play a role in suppressing excessive mixing in

According to this embodiment, the first discharge air may flow forward mainly through the first flow passage S1, and the second discharge air may flow forward mainly through the third flow passage S3. Mixed air in which a part of the upper region of the first discharge air and a part of the lower region of the second discharge air are mixed may flow forward through the second flow path S2.

That is, in the air guide 400 of the present embodiment, a significant portion of the first discharge air and the second discharge air is discharged forward through the first flow passage S1 and the third flow passage S3 in a state in which they are not mixed with each other. , It is possible to suppress excessive mixing of the first discharge air and the second discharge air in the front space (S).

Such an air guide 400 can effectively suppress the generation of vortices in the front space S, and effectively suppress the occurrence of deterioration in exhaust performance and backward flow of exhaust into the inside of the door 150 due to vortexes. there is.

In addition, the inner cover protrusion 220 and the connecting portion 400c provided to fix the air guide 400 to the control panel 200 may be disposed between the exhaust vent 122 and the exhaust vent 122 .

The inner cover protrusion 220 and the connecting portion 400c disposed in this manner cover the partition wall 121 from the front of the partition wall 121 so as not to be seen, and are disposed at a position that does not overlap with the exhaust port 122, so that the cover projections 210 and 220 ) or flow path resistance generated by the air guide 400 can be effectively reduced.

In addition, as described above, the front end 401 of the air guide 400 disposed on the front side of the front space S in the front space S has upper and lower contact with at least a portion of the windshield 153 of the door 150. It can be arranged at a position overlapping in the direction.

As an example, the front end 401 of the air guide 400 is disposed at the same position as the rear end of the windshield 152 in the front-back direction, or at a position more protruding forward than the rear end of the windshield 152 can be placed.

In this way, since the air guide 400 is disposed at a position biased forward in the front space S, the flow of air flowing toward the front of the cooking appliance in the front space S is more reduced by the air guide 400. can be guided effectively.

In addition, since the air guide 400 is disposed at a position where the air guide 400 can be seen from the outside of the cooking appliance as described above, the aesthetics provided by the air guide 400 can be expressed more effectively.

[Third embodiment of air guide]

39 is an enlarged view of a portion of a cooking appliance having an air guide according to a third embodiment of the present invention, and FIG. 40 is an enlarged view of a portion of the cooking appliance shown in FIG. 39 .

Compared to the arrangement in which the first guide part 400a and the second guide part 400a are arranged side by side in the air guide 400 shown in FIGS. 37 and 38, the air guide 500 according to another embodiment of the present invention In ), as shown in FIGS. 39 and 40, the first guide part 500a and the second guide part 500a may be disposed not side by side.

The first guide part 500a and the second guide part 500b may form a partitioning surface crossing the front space in the horizontal direction. For example, the upper and lower surfaces of the first guide part 500a and the second guide part 500b may each form a partitioning surface, and each partitioning surface may be formed in a plane.

According to this embodiment, when viewed in the lateral direction, the partitioning surface of the first guide part 500a and the partitioning surface of the second guide part 500b may be disposed parallel to each other.

As an example, the first guide part (500a) and the second guide part (500b) have a distance between the first guide part (500a) and the second guide part (500a) greater than the distance between the rear ends of the second guide part (500b). The distance between the front ends of the two guide parts 500b may be formed to be large.

Accordingly, the air passing through the air guide 500 spreads over a wide range in the vertical direction and can be discharged forward, so that the exhaust efficiency through the front gap of the cooking appliance can be further improved.

In addition, as the first guide part 500a and the second guide part 500b are inclinedly disposed as described above, the inlet of the first passage S1 and the entrance of the third passage S3 are of the second passage S2. It can be further extended than the entrance.

Accordingly, since the first discharge air and the second discharge air tend to be discharged mainly through the first flow path S1 or the third flow path S3 rather than the second flow path S2, the control in the front space S is increased. Excessive mixing of the first discharge air and the second discharge air can be suppressed more effectively.

[The 4th embodiment of the air guide]

41 is an enlarged view of a portion of a cooking appliance according to a fourth embodiment of the present invention, and FIG. 42 is a front view of a cooking appliance according to a fourth embodiment of the present invention. In addition, FIG. 43 is an exploded rear perspective view showing an exploded state of the door, control panel, and air guide shown in FIG. 42, and FIG. 44 is an enlarged view showing a portion of the door and air guide shown in FIG. 43 in an enlarged manner.

Referring to FIGS. 41 to 44 , the air guide 600 may be disposed between the door 150 and the control panel 200 like the air guides exemplified in the above-described embodiment. The air guide 600 may partition the space between the door 150 and the control panel 200 vertically.

The air guide 600 is disposed in the front space (S), and may partition at least a portion of the front space (S) into a first space (S1) and a second space (S2).

The lateral length, that is, the width, of the air guide 600 may be a length corresponding to the lateral length of the front space (S). For example, the width of the air guide 600 may correspond to at least one of the lateral length of the control panel 200 and the lateral length of the door 150 .

In this embodiment, the first space (S1) is a space between the control panel 200 and the air guide 600, the second space (S2) is a space between the air guide 600 and the door 150 can be defined as

More specifically, the first space (S1) is a space between the guide body portion 610 and the control panel 200 to be described later, and the second space (S2) is the guide body portion 610 to be described later and the door ( 150) can be defined as being the space between. The first space (S1) and the second space (S2) may be partitioned vertically by the guide main body 610.

The air guide 600 is disposed in the front space (S), and may be disposed in an area biased toward the front of the front space (S). In the air guide 600, the front area of the front space S may be divided into a first space S1 and a second space S2.

The air guide 600 may include a guide body 610 . The guide body portion 610 occupies most of the area of the air guide 600, and may form most of the external appearance of the air guide 600.

The guide main body 610 is disposed between the control panel 200 and the door 150 to partition the space between the control panel 200 and the door 150 vertically. The guide main body 610 may divide the space between the control panel 200 and the door 150 into an upper first space S1 and a lower second space S2.

As an example, the guide main body 610 may be formed in a flat shape parallel to the bottom surface of the control panel 200 or the top surface of the door 150 . The guide body portion 610 may be formed in a shape including a plane orthogonal to the vertical axis.

The air guide 600 may further include an extension part 615. The extension part 615 may be disposed on both sides in the lateral direction of the guide body part 610 . This extension 615 may be formed to protrude from the guide body 610 in the lateral direction.

The extension part 615 is neither a part involved in coupling the air guide 600 and the main body 100 nor a part involved in inducing an exhaust flow. The length of the extension part 615 may be set shorter than the total length of the guide body part 610 and the air guide 600.

Since the extension part 615 is formed in a form in which the length of the extension part 615 is shorter than the total length of the air guide 600, the overall size and weight of the air guide 600 may not be unnecessarily increased.

The extension part 615 may be disposed biased toward the front side on the air guide 600. Preferably, the guide body portion 610 and the extension portion 615 may be connected in the lateral direction so that the front end portion of the extension portion 615 and the front end portion of the guide body portion 610 are disposed on the same line. .

In this embodiment, the extension portion 615 is illustrated as protruding from the guide body portion 610 to the same length as the guide body portion 610 .

Accordingly, despite the fact that the length of the extension part 615 is set short compared to the overall length of the air guide 600, the appearance of the air guide 600 seen from the front can be formed in a smooth continuous form.

In addition, the extension part 615 may be disposed in front of the protruding surface part 123 (see FIG. 4). As described above, the protruding surface portion 123 is formed to protrude forward from the side end of the front panel 120 .

The extension part 615 disposed in front of the protruding surface part 123 is formed to have a shorter length than the guide body part 610 as described above and is biased toward the front side on the air guide 600, so that the protruding surface part 123 ) to avoid interference.

That is, the extension part 615 formed in the above shape avoids interference with the protruding surface part 123, while maintaining the aesthetics of the air guide 600 seen from the front, and the size and weight of the air guide 600. The effect of preventing this unnecessary increase can be provided together.

45 is a cross-sectional side view showing internal structures of a door and an air guide of a cooking appliance according to a fourth embodiment of the present invention, and FIG. 46 is a cross-sectional perspective view showing a connection structure between an air guide and a door.

43 to 46, the air guide 600 is disposed between the door 150 and the control panel 200, and may be installed on the door 150. The air guide 600 may be installed on the top cover 157 disposed on top of the door 150.

In this embodiment, the air guide 600 is illustrated as being integrally formed with the door 150. The air guide 600 may be installed on the door 150 in a form connected to the top cover 157.

To this end, the air guide 600 may further include a connection protrusion 620. The connection protrusion 620 may be formed to protrude upward from the door 150 toward the air guide 600 .

The connection protrusion 620 may be disposed between the top cover 157 and the guide body 610 . The connection protrusion 620 may connect the top cover 157 and the guide body 620 while separating the top cover 157 and the guide body 620 by a predetermined distance in the vertical direction. That is, the connection protrusion 620 may connect the door 150 and the air guide 600 while separating the door 150 and the air guide 600 by a predetermined distance in the vertical direction.

A plurality of connecting protrusions 620 may be disposed between the door 150 and the air guide 600, more specifically between the top cover 157 and the guide body 610. The plurality of connecting protrusions 620 may be spaced apart from each other at predetermined intervals in the lateral direction.

Accordingly, the guide body 610 is disposed upwardly from the door 150 by a predetermined distance, and a passage is formed between the plurality of connection protrusions 620 to open the front space S toward the front of the cooking appliance. can

As an example, the air guide 600 may be integrally formed with the top cover 157. According to this, the top cover 157, the connection protrusion 620, and the guide body 610 may be integrally formed. In addition, extensions 615 disposed on both sides of the guide body 610 may also be integrally formed with them.

For example, the top cover 157 may be formed of a plastic material together with the air guide 600 including the connecting protrusion 620 . The top cover 157 is injection molded together with the air guide 600 including the connection protrusion 620 and may be integrally formed with the air guide 600 .

In this case, since the manufacturing of the top cover 157, the manufacturing of the air guide 600, and the coupling work of the top cover 157 and the air guide 600 can be completed by one molding operation, the air guide ( 600) can provide an effect of reducing cost and time required for manufacturing and installation work.

As another example, the air guide 600 may be formed of a metal material. For example, the air guide 600 may be formed of a metal material having excellent heat resistance and a luster peculiar to metal. The air guide 600 is not easily deformed even at high temperatures, is not easily damaged even when impacted, and can contribute to improving the aesthetics of the cooking appliance through its metallic luster.

In this case, both the top cover 157 and the air guide 600 may be made of a metal material, or the top cover 157 may be made of a plastic material and only the air guide 600 may be made of a metal material.

When the top cover 157 and the air guide 600 are formed of a metal material, the top cover 157 and the air guide 600 may be integrally cast.

When the top cover 157 is made of plastic and only the air guide 600 is made of metal, it is an insert injection method in which injection is made with a lower part of the connecting protrusion 620 inserted into the top cover 157. The top cover 157 and the air guide 600 may be manufactured.

Meanwhile, the top cover 157 may be detachably coupled to the door 150 . That is, the top cover 157 and the air guide 600 of this embodiment can be separated from the door 150 as needed and reattached to the door 150.

The top cover 157 and the air guide 600 can be easily cleaned or repaired while being separated from the door 150, and can be easily and quickly replaced when deteriorating or damaged.

Meanwhile, the air guide 600 integrally formed with the top cover 157 as described above can move together with the door 150 . For example, when the door 150 rotates forward to open the cooking chamber 101, the air guide 600 may move forward together with the door 150.

When the air guide 600 is installed on the control panel 200, the air guide 600 may be disposed at a position to cover the exhaust port 122 from the front. The air guide 600 disposed at such a location may become an obstacle preventing a user from approaching the exhaust vent 122 from the front of the cooking appliance.

For example, when a user wants to clean the exhaust port 122 and its surroundings, the air guide 600 fixed to the lower side of the control panel 200 may become an obstacle obstructing this.

However, as illustrated in this embodiment, when the air guide 600 is installed on the door 150, when the door 150 is rotated forward to clean the exhaust port 122 and its surroundings, the air guide 600 It also moves together with the door 150.

Accordingly, the front side of the exhaust port 122 blocked by the air guide 600 is completely opened, and the user can easily access the exhaust port 122 and its surroundings.

That is, since the air guide 600 is installed on the door 150 instead of being installed on the lower side of the control panel 200, the exhaust port 122 and its surroundings can be cleaned effectively.

47 is a front view showing a part of the front of the cooking appliance according to an embodiment of the present invention.

Referring to FIG. 47 , the air guide 600 may be connected to the door 150 through the connecting protrusion 620 and supported by the door 150 .

The connection protrusion 620 may support the guide body 610 while separating the guide body 610 upward from the door 150 . Preferably, the air guide 600 supported by the connection protrusion 620 may be disposed at a central position.

At least one of the plurality of connecting protrusions 620 may be disposed at a position capable of covering at least a portion of the latch 140 from the front side. At least a portion of the latch 140 is covered by the connecting protrusion 620 arranged in this manner. Accordingly, when viewed from the front, at least a portion of the latch 140 is hidden by the connection protrusion 620 and is not visible.

As an example, the connection protrusion 620 may be formed in a protruding form from the upper end of the door 150 to a central position. The connection protrusion 620 may cover the lower half of the latch 140 exposed through the front gap from the front.

The connection protrusion 620 is formed to protrude from the door 150 by a length required to connect the air guide 600 with the door 150, while extending the control panel 200 by a length required to cover the lower half of the latch 140. ) can be formed to protrude from.

That is, the connection protrusion 620 only protrudes as long as it can cover the lower half of the latch 140 while fixing the air guide 600 to the central position, and does not protrude any longer.

These connection protrusions 620 cover a portion of the latch 140, which is a part that can greatly affect the front aesthetics of the cooking appliance, and also arranges the air guide 600 in the central position, so that the cooking appliance can contribute to effectively improving the front aesthetics of the

As another example, the air guide 600 is disposed in the front gap, and may be disposed at a position more inclined downward from the center in the vertical direction of the front gap.

Considering that the user's eye level is higher than the height of the air guide 600 disposed between the door 150 and the control panel 200 in general, the air guide 600 should be placed at the above position so that the user can The guide 600 becomes more identifiable.

In addition, the air guide 600 must be disposed at a position where the air guide 600 can be seen from the outside of the cooking appliance, so that the aesthetics provided by the air guide 600 can be expressed more effectively.

That is, since the air guide 600 is disposed at a position more biased downward from the center of the front gap in the vertical direction, it is possible to effectively form a sense of aesthetics.

In addition, when the air guide 600 is disposed at the above position, the length of the connecting protrusion 620 in the vertical direction can be shortened accordingly.

Since the air introduced into the front space S through the exhaust port 122 (hereinafter referred to as "first exhaust air") is discharged in a high temperature state, it shows an upward flow while passing through the front space S. . Accordingly, the flow of the first exhaust air may be mainly induced toward the first space S1.

A part of the first exhaust air may flow toward the first space S1 or be mixed with the air introduced into the front space S through the door exhaust port 152, but the main flow of the first exhaust air is mainly the first space. (S1) side.

The door exhaust port 152 is disposed on the lower side of the air guide 600. Therefore, the flow of air (hereinafter, referred to as “second exhaust air”) introduced into the front space S through the door exhaust port 152 is directed toward the second space S2 formed on the lower side of the air guide 600. can be mainly induced.

Part of the second exhaust air may flow toward the second space S2 or may be mixed with the first exhaust air, but the main flow of the second exhaust air may be mainly directed toward the second space S2.

When the flow of the first exhaust air and the flow of the second exhaust air are excessively mixed in the front space (S), there is a possibility that a vortex is generated in the front space (S).

Considering this point, in this embodiment, the air guide 600 is disposed on the front side of the front space S, and the flow of air flowing through the exhaust passage is branched up and down by the air guide 600. do.

When the flow of air branched by the air guide 600 is formed in the front space (S) in this way, the possibility of vortex generation in the front space (S) can be significantly reduced.

That is, the air guide 600 disposed on the front side of the front space S in the front space S is disposed on the exhaust passage and diverges the flow of air flowing through the exhaust passage, thereby reducing the front space S It is possible to effectively suppress the generation of vortices within.

In general, the temperature of the first exhaust air discharged from the electrical compartment 103 may be higher than the temperature of the second exhaust air exhausted from the door 150 . Considering this point, the air guide 600 of this embodiment may induce a flow of air so that the first exhaust air flows through the first space S1.

That is, in the air guide 600 of the present embodiment, the air flows so that the first exhaust air, which is relatively hotter than the second exhaust air, flows through the first space S1, which is a space biased toward the upper side of the front space S. can induce Such an air guide 600 may induce an exhaust flow such that a distance between the flow of the first exhaust air and the door 150 is increased.

Accordingly, since the exhaust is made toward the front of the cooking appliance from the side far from the door 150 in the front space S, the distance between the hot air discharged to the front of the cooking appliance and the door 150 becomes that much greater.

As the distance between the hot air discharged from the front of the cooking appliance and the door 150 increases in this way, the risk of the temperature of the door 150 rising due to contact between the hot air and the door 150 is reduced.
