The present disclosure relates to a storehouse.
A storehouse may include a storage space for storing goods. Examples of the storehouse may include a refrigerator.
The refrigerator is an apparatus that cools objects to be cooled (e.g., food, drugs, and cosmetics) (hereinafter referred to as food for convenience), or stores food at low temperature so as to prevent spoilage and deterioration. The refrigerator includes a storage space in which food is stored, and a refrigeration cycle part that cools the storage space.
The refrigeration cycle part may include a compressor, a condenser, an expansion mechanism, and an evaporator, through which a refrigerant circulates.
A refrigerator according to the related art may include an outer case, and an inner case located inside the outer case and having an opened front side. Such a refrigerator may include a cold air discharge duct disposed inside the inner case to partition the inside of the inner case into a storage space and a heat exchange space. For example, the storage space may be defined in front of the cold air discharge duct, and the heat exchange space may be defined in the rear of the cold air discharge duct. An evaporator and an evaporating fan may be disposed in the heat exchange space.
The refrigerator may have a separate machine space defined outside the inner case. A compressor, a condenser, and a condensing fan may be disposed in the machine space. The compressor in the machine space may be connected to the evaporator in the heat exchange space through a refrigerant pipe.
The storage space may be provided with a withdrawable drawer. A plurality of the drawers may be provided in a vertical direction.
However, the refrigerator according to the related art as described above has the following problems.
First, the compressor in the machine space and the evaporator in the inner case are disposed in spaces separated from each other and are connected to each other by the refrigerant pipe. Therefore, when it is necessary to repair the refrigeration cycle part, it is inconvenient to take out food stored in the refrigerator so as to check and repair failure.
Second, since the evaporator has to be integrally formed inside the refrigerator body and the evaporator has to be fixed to the refrigerator body by welding or the like, there is an inconvenience in manufacturing the refrigerator. In addition, when the evaporator defrosts, heat exchange with the storage space increases the internal temperature of the refrigerator.
Third, since the heat exchange space is disposed in the rear of the storage space, the width of the rear wall of the refrigerator body in the front-and-rear direction increases as much as the size of the heat exchange space. Therefore, the volume of the storage space is reduced as much.
In order to solve these problems, a refrigerator including a cooling module that integrally configures a heat absorbing portion and a heat dissipating portion has been proposed.

At least a part of the second passage may be provided to be exposed to the second storage space.
Fourth, the fluid generator may be disposed in at least one of the inside of the first passage and the inside of the second passage. In this case, since the distance between the first heat exchanger and the fluid generator may be separated, there is an advantage that can reduce a dead zone that may occur in the flow passage of the fluid. The passage on which the fluid generator is disposed may include a portion protruding toward the first storage space. Therefore, the volume of the first storage space may be increased. The fluid generator may be disposed inside the protruding portion.

For example, the fluid generator may include a fan and a fan housing.

The heat exchanger case 200 may be in a state of being spaced upward apart from the fluid collecting surface of the tray 130 by the support wall 133. Therefore, the heat exchanger case 200 may not be submerged in the condensed fluid collected in the tray 130.
The drain hole 208 may be located at the center with respect to the left-and-right direction of the heat exchanger case 200. When the center line (80) that bisects the heat exchanger case 200 to the left and right is defined, the center line (80) may pass through the drain hole 208.
Based on the center line (80), the heat exchanger case 200 may be bilaterally symmetrical.

Based on
The first predetermined angle (θ1) and the second predetermined angle (θ2) may have the same value. For example, the first and second predetermined angles (θ1 and θ2) may be in a range of 7° to 10°.
Since the first predetermined angle (θ1) and the second predetermined angle (θ2) have the same value, the first and second bottom portions 207a and 207b may be symmetrical left and right about the drain hole 208, and the thickness of the lower heat insulating wall of the heat exchanger case 200 may be formed evenly based on the drain hole 208.
As another example, the first predetermined angle (θ1) and the second predetermined angle (θ2) may have different values. However, even in such a case, the first and second predetermined angles (θ1 and θ2) may be in a range of 7° to 10°.
As described above, since the bottom portion 207 is inclined downward toward the drain hole 208, the condensed fluid collected in the bottom portion 207 can be easily discharged into the drain hole 208.
Based on
The first inclined portion 207c may be defined below the first heat exchanger 220.
The second inclined portion 207d may be located closer to the fan assembly 300 than the first inclined portion 207c.
The drain hole 208 may be defined closer to the center of the fan assembly 300 than the center of the first heat exchanger 220.
In order to further secure a space in which the fan assembly 300 is installed, the fourth predetermined angle (θ4) may be greater than the third predetermined angle (θ3). That is, since the fourth predetermined angle (θ4) is relatively great, the space of the case accommodation portion 205 defined above the second inclined portion 207d can be formed to be large.
Since the fourth predetermined angle (θ4) is greater than the third predetermined angle (θ3), the condensed water generated in the first heat exchanger 220 may be easily discharged to the drain hole 208 without reducing the flow rate while passing through the first inclined portion 207c and the second inclined portion 207d.
However, although the fourth predetermined angle (θ4) is greater than the third predetermined angle (θ3), the third and fourth predetermined angles (θ3 and θ4) may be in a range of 7° to 10°.
Based on
Since the uppermost end of the third inclined portion 207e is located lower than the uppermost end of the first inclined portion 207c or the uppermost end of the second inclined portion 207d, a large space in which the fan assembly 300 is installed can be secured.
The fifth predetermined angle (θ5) may have the same value as the third predetermined angle (θ3).
The fifth predetermined angle (θ5) may have a smaller value than the fourth predetermined angle (θ4).
The fifth predetermined angle (θ5) may be in a range of 7° to 10°.
The first to fifth setting angles may be determined as appropriate values in consideration of the thickness of the case insulating material 213 of the heat exchanger case 200, the depth of the drain hole 208, and the arrangement of the first heat exchanger 220 and the fan assembly 300.

The support flat portion 133b1 may support the bottom lower end portion 210f1 of the heat exchanger case 200.
A height Hr of the support flat portion 133b1 may be less than a height Hf of the support front portion 133a.
The height Hr of the support flat portion 133b1 may be the same as the height of the support rear portion 133c.
The height Hf of the support front portion 133a or the height Hr of the support flat portion 133b1 may be lower than the height of the second portion 132b of the storage wall 132.
The first portion of the support wall 133, for example, the support flat portion 133b1 is disposed closer to the drain hole 208 than the second portion of the support wall 133, for example, the support rear portion 133c. Accordingly, the fluid may be easily discharged from the inside of the heat exchanger case 200.
The tray body 131 defines a wide fluid collecting surface, and the storage wall 132 has a relatively low height. Thus, the fluid stored in the tray 130 overflows to the outside of the tray 130.
An embodiment related to the tray 130 and the heat exchanger is as follows. The tray may include any one of the following embodiments or a combination of two or more of the following embodiments.
At least a part of the refrigerant pipe connected to the first heat exchanger 220 and the refrigerant pipe connected to the second heat exchanger 123 may be disposed to pass through a space defined between the tray 130 and the second wall.
The second wall may be provided as a wall in which a discharge passage is defined in a part of a plurality of walls. For example, the bottom surface of the heat exchanger case 200 may be provided as a wall defining the drain hole 208.
At least a part of the refrigerant pipe connected to the first heat exchanger 220 and the refrigerant pipe connected to the second heat exchanger 123 may be disposed to pass through a space defined between the tray 130 and the wall where the discharge passage is defined.
A compressor may be provided upstream of the second heat exchanger 123, and at least a part of the refrigerant pipe between the compressor 121 and the second heat exchanger 123 may be disposed to pass through one side of the tray 130 or disposed in a part of the second wall.
A first heat exchanger 220 may be provided downstream of the second heat exchanger 123, and at least a part of the refrigerant pipe between the first heat exchanger 220 and the second heat exchanger 123 may be disposed in a part of the second wall while being in contact with the refrigerant pipe flowing out from the first heat exchanger 220.
A method for assembling the heat exchange device 100 with the storehouse body 10 and an assembly structure, according to an embodiment of the present disclosure, will be described with reference to
The first heat exchanger 220 may be accommodated in the heat exchanger case 200.
The second heat exchanger 123 and the heat exchanger case 200 in which the first heat exchanger 220 is installed may be installed on the base 110. The compressor 121 and the second fan 125 may be installed on the base 110 together.
The second heat exchanger 123, the compressor 121, and the second fan 125 may be installed in the third storage space 17.
The base 110 may be configured as a common plate for the first and second heat exchangers 220 and 123, and may be configured as a separate plate for separately installing the first and second heat exchangers 220 and 123.
The heat exchange device 100 may be manufactured by coupling the first and second heat exchangers 220 and 123. In an embodiment, the first and second heat exchangers 220 and 123 may be connected through a pipe as a component constituting the refrigeration cycle. The pipe may be a refrigerant pipe.
The heat exchange device 100 may be disposed in the storehouse body 10.
The heat exchange device 100 may be inserted through the opened front end portion of the device accommodation space 18.
The heat exchange device 100 may slide into the device accommodation space 18.
As another example, the heat exchange device 100 may be fixed at a predetermined position, the storehouse body 10 may be moved toward the heat exchange device 100, and the heat exchange device 100 may be inserted into the device accommodation space 18.
When the heat exchange device 100 is inserted into the device accommodation space 18, the upper portion of the heat exchanger case 200 may be located below the partition wall 50.
The upper end portion of the heat exchanger case 200 may be in a state of being spaced downward apart from the bottom surface of the partition wall 50, and the sealing member 240 installed in the heat exchanger case 200 may be in a state of not being in contact with the bottom surface of the partition wall 50.
A fluid generator may be disposed downstream of the first heat exchanger 220. The fluid generator may include a fan assembly 300. The fan assembly 300 may include the first fan 310. The first fan 310 may be disposed inside the shroud 320.
For example, at least a part of the first fan 310 may be disposed inside the heat exchanger case 200.
However, the present disclosure is not limited thereto, and the first fan 310 may be installed outside the heat exchanger case 200. For example, the first fan 310 may be disposed inside the partition wall 50. As another example, the first fan 310 may be disposed inside the first storage space 15 or inside the duct 30.
In a state in which the heat exchange device 100 is inserted into the device accommodation space 18, the fan assembly 300 may be assembled to the storehouse body 10 through the partition wall 50.
The first fan 310 provided in the fan assembly 300 may be disposed at the outlet side of the first heat exchanger 220.
By moving the heat exchanger case 200 toward the partition wall 50 by a predetermined distance ΔH, the partition wall 50 and the heat exchanger case 200 may be in contact with each other.
When the heat exchanger case 200 moves, the heat exchanger case 200 may be guided by the second portion 132b of the storage wall 132, and thus, may be stably moved without shaking.
The heat exchanger case 200 may move until the sealing member 240 comes into contact with the partition wall 50.
While the sealing member 240 is in contact with the partition wall 50, the protruding height of the sealing member 240 may decrease or disappear.
The gap between the heat exchanger case 200 and the partition wall 50 may be sealed by the sealing member 240 to prevent cold air in the heat exchanger case 200 from leaking out from the duct 30.
A means for moving the heat exchanger case 200 toward the partition wall 50 may be variously proposed.
For example, the heat exchanger case 200 may be coupled to the partition wall 50.
As another example, a lifting device may be provided around the heat exchanger case 200 to lift the heat exchanger case 200.
As another example, a hook device may be provided on the heat exchanger case 200 or the storehouse body 10 so that the heat exchanger case 200 is caught on the storehouse body 10.
The fluid in the first storage space 15 may be introduced into the inside of the second storage space, for example, the inside of the heat exchanger case 200, through the inlet portion 51 of the partition wall 50, and may pass through the first heat exchanger 220. In the process of passing through the first heat exchanger 220, the fluid may flow from the front portion to the rear portion of the first heat exchanger 220.
The fluid passing through the first heat exchanger 220 may pass through the first fan 310, and the fluid passing through the first fan 310 may be discharged from the fan assembly 300 through the fan outlet portion 326 of the shroud 320 and may flow into the duct 30.
When the second fan 125 is driven, a passage f3 through which the fluid flows inside or outside the tray 130 via the space defined between the tray 130 and the second wall may be formed.
A fluid fw generated inside the second storage space 16, for example, the heat exchanger case 200 may be collected into the tray 130 through the drain hole 208.
According to an embodiment of the present disclosure, first and second storage spaces are fluidly connected to each other. Therefore, the fluid heat-exchanged in a first heat exchanger may be easily supplied to the first storage space, and the fluid in the first storage space may be easily returned to the second storage space. Therefore, the industrial applicability is remarkable.
