An upper plate 12 is positioned between the oven unit 30 and the cooktop unit 20 above the cooking chamber 31. The heat emitted from the cooking chamber 31 is primarily blocked by the top plate 12. The top plate 12 is formed in the shape of a square plate having a predetermined thickness. The upper plate 12 separates the space in which the cooking chamber 31 is located from the upper space thereof.

In addition, the upper space of the upper plate 12 is separated by the partition plate 53. The partition plate 53 is provided in the form of a rectangular plate having a predetermined thickness and is long in the horizontal direction.

The partition plate 53 is located at the rear of the control panel 51 and is fixed to the upper plate 12 to separate the upper space of the cooking chamber 31 into the first half and the second half.

In the first half space separated by the partition plate 53, the controller 50 is formed in which a plurality of control components including the circuit board are located. In the second half space separated by the partition plate 53, an electric equipment chamber 60 in which a cooling fan 61 or the like is located is formed.

A plurality of the cooktop heaters 22 are positioned to dissipate heat at the upper side of the electric compartment 60, and at this time, the heat dissipated from the cooktop heaters 22 by the partition plate 53 is controlled by the control unit ( To block 50).

That is, the partition plate 53 serves as a heat insulator to block heat emitted from the cooktop heater 22 toward the controller 50. Of course, the front and rear of the partition plate 53 is further provided with a heat insulating material for insulating the control unit 50 is configured to prevent the temperature rise of the control unit 50.

The cooling fan 61 is located at the rear end of the electric compartment 60. The cooling fan 61 performs a function of sucking the air in front and exhausting it forward while rotating.

At this time, the front plate 11 is formed with an inlet port 13 and an exhaust port 14 for providing a flow path of air by the rotational movement of the cooling fan 61. The inlet 13 provides a passage through which air in the outer space flows into the inner space of the main body 10. The exhaust port 14 provides a passage through which the internal air of the main body 10 flows to the external space.

The intake port 13 and the exhaust port 14 are formed in the front plate 11 positioned between the door 32 and the control panel 51. The exhaust port 14 is formed at an upper center portion of the door 32, and the intake port 13 is formed at both sides of the exhaust port 14.

A first flow path hole (15 of FIG. 6) is formed on a rear upper surface of the inlet port 13 to provide a passage through which external air flowing through the inlet port 13 flows upward. The outside air passing through the inlet port 13 flows upward by the first channel hole 15. The outside air flowing upward cools the control part while passing through the control part 50.

The first channel holes 15 are located on both sides of the outlet portion of the exhaust duct 62, which will be described later. That is, it is formed in the front end portion of the upper plate 12 forming the upper surface of the inlet port 13 located on both sides of the exhaust port 14.

The first channel hole 15 is formed in a grill shape in which a portion of the upper plate 12 is cut off while having a predetermined area. Of course, it is also possible to form in a form other than the grill form.

The first passage hole 15 is formed in a grille shape to prevent a plurality of electric wires connected to the controller 50 from being struck by the inlet 13. In addition, the wires are not visible through the inlet 13 when viewed from the front.

In addition, since the first passage hole 15 is formed in a grill shape, the first passage hole 15 may have an advantage of visually determining whether the wire is connected during the assembly of the product. This has the advantage of reducing the errors that occur during the assembly process.

On the other hand, the suction duct 64 is formed at the rear of the control unit 50 to form a second flow path through which the air cooling the control unit 50 moves to the rear. The suction duct 64 is elongated in the front-rear direction in the shape of a hexahedron having an open front and rear surfaces. At this time, the cross-sectional area of the front and rear surfaces of the suction duct 64 is the same.

The inlet portion through which air enters the inner space of the suction duct 64 is spaced apart from the controller 50 by a predetermined distance. The outlet portion through which air is exhausted is located in front of the cooling fan 61. Therefore, the suction duct 64 guides the air cooled to the controller 50 to the rear through the internal space in accordance with the rotational movement of the cooling fan 61.

In this way, the suction duct 64 forms a second flow path for flowing air flowing along the first flow path through the inner space to the rear.

An exhaust duct 62 is formed below the suction duct 64 to form a third flow path while guiding air in the space inside the main body 10. The exhaust duct 62 is formed in the form of a hexahedron having a predetermined internal space and at least the rear and front surfaces thereof are open.

An outlet portion through which the air is exhausted to the front of the main body 10 through the internal space of the exhaust duct 62 is connected to the exhaust port 14, and air is introduced into the internal space of the exhaust duct 62. The inlet portion is located in front of the cooling fan 61.

The exhaust duct 62 forms a third flow path through which air flowing along the second flow path flows forward through an internal space.

The exhaust duct 62 is formed of a hexahedron whose cross section is gradually widened toward the front in a shape in which the front face is longer in the horizontal direction than the rear face. This is to reduce the flow rate of the air flowing forward while being guided by the internal space of the exhaust duct 62.

The third flow path formed by the internal space of the exhaust duct 62 gradually decreases in flow velocity by the exhaust duct 62, which has a larger cross-sectional area as it flows forward. Air flowing by the third channel is exhausted to the front of the main body 10 in a state in which the flow rate is reduced through the exhaust port (14).

At this time, the longitudinal length of the exhaust duct 62 is formed longer than the longitudinal length of the suction duct (64). This is because the inlet portion of the suction duct 64 is spaced apart from the controller 50 at a predetermined interval.

As such, the reason why the inlet portion of the suction duct 64 is spaced apart from the controller 50 is that the air passing through the first flow hole 15 passes through the controller 50 to cool the controller 50. Let's do it. The controller 50 is formed to have a predetermined distance from the controller 50 in order to introduce the air cooled by the controller 50 into the inner space of the suction duct 64.

That is, the air flowing along the first passage is formed to have a predetermined distance from the controller 50 in order to allow more air to be sucked into the inner space of the suction duct 64.

In addition, the exhaust duct 62 has a larger cross-sectional area of the inner space toward the front, and the suction duct 64 has the same cross-sectional area of the inner space. The internal space cross-sectional area of the suction duct 64 is formed to maintain the same inlet suction force and outlet suction force of the suction duct 64.

A plurality of exhaust holes 63 having a predetermined area are formed at both front end portions of the exhaust duct 62. The exhaust hole 63 flows a part of the air flowing forward through the inner space of the exhaust duct 62 to the outer space of the exhaust duct 62. As such, when a part of the air flowing in the internal space of the exhaust duct 62 through the exhaust hole 63 flows to the external space of the exhaust duct 62, the pressure at the outlet portion of the exhaust duct 62 is reduced. This lowers the flow rate of air.

As the flow velocity of air at the outlet portion of the exhaust duct 62 is reduced, the flow velocity of the air exhausted to the outer space of the main body 10 through the exhaust port 14 is lowered.

As the flow rate of the air exhausted to the outer space of the main body 10 is lowered, there is an advantage of ensuring the safety of the user, there is an advantage that can resolve the user's emotional dissatisfaction.

Hereinafter, the air flow of the cooking apparatus according to the present invention having the configuration as described above will be described.

When the user manipulates the input unit 52 provided to the control panel 51 to cook food, the heater located in the inner space of the main body 10 is driven. At the same time, the cooling fan 61 is driven.

A suction force is generated at the inlet portion of the suction duct 64 by the driving of the cooling fan 61, and the outside air of the main body 10 is introduced through the suction port 13. The outside air sucked through the suction port 13 flows to the controller 50 through the first flow passage hole 15.

That is, the outside air sucked through the suction port 13 flows along the first flow path to cool the controller 50. The air cooled by the controller 50 flows to the inlet portion of the suction duct 64. Air flowing to the inlet portion of the suction duct 64 is guided by the internal space of the suction duct 64 and flows along the second flow path to the cooling fan 61.

Air flowing into the cooling fan 61 flows into the inlet portion of the exhaust duct 62. Air flowing to the inlet portion of the exhaust duct 62 is guided by the internal space of the exhaust duct 62 along the third flow path and flows forward. Air flowing along the third flow path flows to the outlet portion of the exhaust duct 62.

At this time, while flowing to the outlet portion of the exhaust duct 62, the flow rate of air is reduced in accordance with the change in the internal space cross-sectional area of the exhaust duct 62. A portion of the air flowing along the third flow passage flows to the outer space of the exhaust duct 62 through the exhaust hole 63.

The decelerated air flowing to the outlet portion of the exhaust duct 62 passes through the exhaust port 14 and is exhausted to the outer space of the main body 10.

According to the cooking appliance according to the present invention as described above, it is possible to expect a smooth effect of cooling the controller of the cooking appliance.

As the cooling of the controller is smooth, an effect of preventing malfunction and thermal damage of the control component may be expected.

In addition, while the wind speed of the exhaust air exhausted forward is reduced to ensure the safety of the user, an effect that can resolve the user's emotional complaints can be expected.

As such, the cooking appliance according to the present invention will have various advantages, and therefore, the cooking appliance according to the present invention will have great applicability in the cooking appliance industry.
