Description

Refrigerator {REFRIGERATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a refrigerator, and more particularly, to a refrigerator having an improved cooling channel and improved cooling efficiency.

Generally, a refrigerator is a device for cryogenic storage of food. The refrigerator includes a freezer room in which food is stored at a relatively low temperature and a refrigerated room in which food is stored at a relatively higher temperature than the freezer room.

In recent years, meaning has been extended to a device for improving the convenience of the user beyond the meaning of a device for simply storing food. Therefore, refrigerators with various additional functions are being developed and produced according to the needs of consumers. In addition, various researches for increasing the efficiency of the refrigerator for energy saving are continuing.

The refrigerator is formed by foaming a heat insulating member in the main body to insulate the storage room and the evaporating room. The heat insulating member is formed by foaming between the inner surface forming the storage chamber and the evaporation chamber and the outer surface forming the outer surface. However, the thermal insulating member may be formed to have a different volume or uneven surface depending on the foaming conditions.

Accordingly, the dimensions of the inner surface are not uniformly formed, and the position of the evaporator which is seated on the inner surface is not uniform. Thus, the evaporator cover attached to the front surface of the evaporator and the evaporator can be combined with an assembly tolerance.

However, due to the assembly tolerance, some of the air introduced into the evaporation chamber escapes without passing through the evaporator. In order to solve such a problem, the elastic material is attached between the evaporator and the evaporator cover, but the assembly is complicated and the material cost is increased.

One aspect of the present invention provides a refrigerator for shutting off the air bypassing the evaporator in the evaporation chamber.

The present invention also provides a refrigerator which is simple to assemble and has a small material cost by forming a blocking part protruding toward the evaporator on the evaporator cover.

The blocking portion may protrude from the evaporator cover toward the evaporator.

The blocking portion may protrude to contact with one side of the evaporator.

The blocking portion may extend in the width direction to correspond to the width of the air passing through the evaporation chamber.

The blocking portion may include at least one bent portion that is bent and extended.

The blocking portion may include a plurality of blocking portions spaced apart in the direction of air passing through the evaporation chamber.

The main body may include an external shape which forms an external appearance, an internal surface forming the storage chamber and the evaporation chamber, and a heat insulating member foamed between the external surface and the internal surface.

The rear surface of the evaporator is installed to be fixed to one side of the inner surface, and the evaporator cover can be positioned on the front surface of the evaporator.

The evaporator cover and the evaporator may be spaced apart from each other by a predetermined distance, and the blocking portion may extend to contact the evaporator.

According to another aspect of the present invention, there is provided a refrigerator including a main body having a storage chamber, a front panel including an evaporator installed at one side of the main body, at least one inlet through which air passing through the evaporator is supplied to the storage chamber, And a rear panel including a blocking portion protruding toward the evaporator for guiding the passage through the evaporator.

In order to block the air bypassing the evaporator, the blocking portion may be protruded to be in contact with the evaporator.

The evaporator may be fixed to one side of the main body, and the rear panel and the front panel may be disposed on one side of the evaporator in order.

And an evaporation chamber located between one side of the main body in which the evaporator is installed and the rear panel and in which the evaporator and air are heat-exchanged.

The blocking portion may be formed to extend to correspond to the evaporating chamber so as to guide the air passing through the evaporating chamber.

And a cool air delivery channel disposed between the rear panel and the front panel and through which air having passed through the evaporator is supplied to the storage chamber.

[ The doors 7 and 9 may include a refrigerator compartment door 7 and a freezer compartment door 9 provided on the refrigerating compartment 3 and the freezing compartment 5, respectively. The refrigerator compartment door 7 and the freezer compartment door 9 are pivotally coupled to the main body 2 so as to be able to open and close the refrigerating compartment 3 and the freezing compartment 5, respectively.

Hereinafter, the refrigerator 1 according to an embodiment of the present invention will be described as a general refrigerator, but the present invention is not limited thereto and can be applied to various types of refrigerators.

At least one shelf 6 may be provided for multi-stage refrigerating chamber 3 and freezing chamber 5 to facilitate storage of the stored product. At least one inlet (42, 46) through which cold air is introduced may be provided at one side of the storage room (3, 5). The air supplied to the storage rooms 3 and 5 through the inlets 42 and 46 can exit the storage rooms 3 and 5 along at least one outlet 44 and 48.

The refrigerating chamber 3 may include a refrigerating inlet 46 and a refrigerating outlet 48 and the freezing chamber 5 may include at least one freezing inlet 42 and a freezing outlet 44, Air entering through the inlets (42, 46) at a relatively low temperature exits the outlets (44, 48) at a relatively high temperature after heat exchange with the stock. By circulating the air, the temperature of the stored product can be appropriately maintained.

The evaporation chamber 30 may be provided inside the main body 2 so as to communicate with the storage chambers 3, 5. The evaporator 30 may be provided with an evaporator 35 for exchanging heat with the air circulating through the storage compartments 3 and 5 and the evaporator compartment 30. The evaporator 35 may be installed to be fixed to one side of the inner surface 11 constituting the evaporation chamber 30. The evaporator 35 may be connected to the compressor 22 or the like to form a refrigerant cycle. The compressor 22 and the like may be disposed inside the machine room 20 formed in the lower portion of the main body 2. [

The evaporator cover 100 may be installed so as to be positioned between the freezing chamber 5 and the evaporation chamber 30, as shown in FIG. The evaporator 30, the evaporator 35 and the evaporator cover 100 installed in the freezing chamber 5 will be described below. These components may be installed in the refrigerating chamber 3. Further, a plurality of refrigerators can be installed in the refrigerator 1, respectively.

The evaporator cover 100 may be arranged to partition the freezer compartment 5 and the evaporator compartment 30. That is, the evaporator cover 100 forms the rear surface of the freezing chamber 5 and forms the front surface of the evaporation chamber 30. [ The evaporator cover 100 includes at least one inlet 42 so that the cool air formed in the evaporator chamber 30 can be moved to the reservoir 3,

The evaporator cover 100 may include a front panel 120 including at least one inlet 42, a rear panel 110 coupled with the front panel 120, and a circulating fan 130. The circulating fan 130 may be installed to supply the air to the storage rooms 3 and 5 through the evaporator 35 by forcibly circulating the air. The front panel 120 and the rear panel 110 may be combined to form a cool air transmission passage 140 through which air can pass.

Referring to FIG. 1, the flow of air flowing in the refrigerator 1 will be schematically described. The air passing through the evaporator 35 by the circulating fan 130 moves to the evaporator cover 100. Air flows along the cold air transfer passage 140 formed by the front panel 120 and the rear panel 110 and is supplied to the freezing chamber 5 through the freezing inlet 42 provided in the front panel 120. [ The air supplied to the freezing chamber 5 circulates through the freezing chamber 5 and exits the freezing chamber 5 through the freezing /

Some air that has passed through the cold air transfer passage 140 without escaping through the freezing inlet 42 may exit the evaporator cover 100 along the delivery port 150. The delivery port 150 is connected to the flow path extending to the refrigerating chamber 3, and air flows along the flow path and is supplied to the refrigerating chamber 3 through the refrigerating inlet port 46. The air supplied to the refrigerating chamber 3 is circulated in the refrigerating chamber 3 and exits from the refrigerating chamber 3 through the refrigerating outflow opening 48.

The refrigerating outlet 48 and the freezing outlet 44 may be formed in the partition 4 separating the refrigerating chamber 3 and the freezing chamber 5, respectively. The air passing through the freezing chamber (5) and the air passing through the refrigerating chamber (3) are moved through different flow paths because the temperatures are different from each other. That is, in the partition wall 4, a flow path through which the air entered through the refrigerating outflow port 48 moves and a flow path through which the air introduced through the refrigerating outflow port 44 move may be provided in an insulated manner.

The air moved along the inside of the partition wall 4 enters the evaporation chamber 30 again and can exchange heat with the evaporator 35. At this time, the air passes through the inner wall 11 constituting the evaporation chamber 30 and the flow path formed by the evaporator cover 100. The evaporator 35 is installed at a predetermined distance from the evaporator cover 100 because the dimensions of the inner top 11 may not be uniform as described above.

Therefore, some of the air passing through the evaporation chamber 30 may not pass through the evaporator 35. The evaporator cover 100 may include a blocking portion 160 protruding toward the evaporator 35 so as to guide the air through the evaporator 35. [ That is, the blocking unit 160 may be installed in the evaporation chamber 30 to block the flow of air bypassing the evaporator 35.

3 is a view showing an evaporator cover 100 of a refrigerator 1 according to an embodiment of the present invention. 4 is a view illustrating a rear panel 110 of an evaporator cover 100 of a refrigerator 1 according to an embodiment of the present invention.

As described above, the evaporator cover 100 may include a front panel 120 and a rear panel 110. As shown in FIG. 3, a cool air transmission passage 140 may be formed on one surface of the front panel 120 coupled with the rear panel 110. The cool air communication passage 140 may be formed on the front surface of the rear panel 110 coupled to the front panel 120.

A delivery port 150 is provided at a lower portion of the front panel 120 so as to be connected to a cool air transmission path 140. A circulation fan 130 may be installed at an upper portion of the front panel 120. [ In addition, the front panel 120 includes at least one freezing inlet 42, so that air flowing through the cold air transmission passage 140 can be supplied to the freezing chamber 5.

The front panel 120 may include a cold air conditioner 142 to change the amount of air passing through the cold air passage 140. As shown in FIG. 2, the cool air adjusting device 142 may be exposed to the rear of the freezer compartment 5 so that the user can operate the cooler 142. The user can control the amount of cool air flowing into the freezing compartment 5 and the refrigerating compartment 3 by operating the cold air conditioner 142. [

One side of the rear panel 110 may be arranged to engage with the front panel 120 and the other side to form an evaporation chamber 30. [ The rear panel 110 may include a first portion 114 for installing the circulating fan 130 and a second portion 112 disposed adjacent to the evaporator 35. The first part 114 may include a circulation hole 115 for passing air therethrough. The circulation port 115 may be provided so that air passing through the evaporation chamber 30 can be moved to the cold air transfer passage 140.

The second portion 112 may be spaced apart from the evaporator 35 by a predetermined distance so as to correspond to a dimensional change of the inner surface 11 as described above. The blocking portion 160 may be formed to protrude from the second portion 112 toward the evaporator 35. The blocking portion 160 may be formed to extend in contact with the evaporator 35 so as to block the air bypassing the evaporator 35.

4, the blocking portion 160 may extend in the width direction so as to correspond to the width of the air passing through the evaporation chamber 30. As shown in FIG. That is, the blocking portion 160 may extend in the width direction of the rear panel 110. The blocking portion 160 may extend in the width direction and may be formed in a thin strip shape in the longitudinal direction.

5 is a view illustrating a rear panel 110a of an evaporator cover of a refrigerator according to another embodiment of the present invention. The blocking portions 170 and 172 may include a plurality of blocking portions disposed apart from each other. The plurality of blocking portions may include an upper blocking portion 170 and a lower blocking portion 172. The upper blocking portion 170 and the lower blocking portion 172 are spaced apart from each other and can more effectively block the air bypassing the evaporator 35.

6 is a view showing a rear panel 110b of an evaporator cover of a refrigerator according to another embodiment of the present invention. The blocking portion 180 may include at least one bent portion 182 that is bent and extended. The blocking portion 180 may be arranged to be vertically spaced by the bent portion 182. However, one side of the blocking portion 180 may be spaced apart to prevent air from passing therethrough.

5 to 6 are views showing another form of the blocking portion, and the contents described above are cited. The blocking portion may be provided in various forms other than the shapes shown in Figs. 4 to 6, and may include all shapes that block the air bypassing the evaporator.
