Description

STOREHOUSE

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.

An embodiment of the present disclosure aims to provide a storehouse in which a first storage space configured to provide a space in which goods are stored is fluidly connected to a second storage space configured to provide a space in which a first heat exchanger is accommodated.

An embodiment of the present disclosure aims to provide a storehouse including a first space and a second space, wherein a first heat exchanger is disposed closer to the first space and a fluid generator is disposed closer to the second space, thereby improving flow performance of a second storage space.

An embodiment of the present disclosure aims to provide a storehouse wherein a direction in which a fluid in a second storage space flows in a first space includes a direction different from a direction in which a fluid flows in a second space, thereby reducing the occurrence of a fluidized bed dead zone in an inner space of a second storage space.

An embodiment of the present disclosure aims to provide a storehouse wherein a passage through which water formed on a surface of a first heat exchanger is discharged to the outside is provided in at least one of a first space and a second space, thereby improving drainage performance in a second storage space.

An embodiment of the present disclosure aims to provide a storehouse including an air guide for changing a flow direction of a fluid passing through a first heat exchanger, thereby reducing a flow resistance while the fluid changes the flow direction.

The heat exchange device 100 further includes a fan assembly 300 for generating the flow. The fan assembly 300 may be provided above the first heat exchanger 220.

The fan assembly 300 may include the first fan 310. The first fan 310 may include a centrifugal fan.

The first fan 310 may include a hub 312 in which the fan motor is located, and a plurality of blades 313 provided on the outer periphery of the hub 312. The hub 312 may be located at the center of the fan suction portion 253.

A central axis of the first fan 310 may be formed in the vertical direction, and the central axis of the first fan 310 may be formed to pass through the first heat exchanger 220.

The fan assembly 300 may include a shroud 320 having a fan seat 322 on which the first fan 310 is installed.

The central axis of the first fan 310 may be located so as to be eccentric in the left-and-right direction with respect to the center of the first heat exchanger 220.

A second center line (ℓ2) passing through the central axis of the first fan 310 may be spaced apart by a separation distance S1 from a first center line (ℓl) passing through the center of the first heat exchanger 220 or the heat exchanger case 200 in the left-and-right direction.

The first center line (ℓl) may pass through the center of the case duct 215.

The separation of the central axis of the first fan 310 is due to the scroll shape of the shroud 320. This shape may improve the static pressure characteristics of the first fan 310.

The first heat exchanger 220 may form a horizontally laid arrangement, the first fan 310 may be disposed above the first heat exchanger 220, and the fluid introduced into the first heat exchanger 220 may flow in different directions around the first heat exchanger 220 to perform a curved flow.

Accordingly, since the distance in the flow direction with respect to the width of the first heat exchanger 220 is long, the dead zone area of the flow may be small. In FIG. 6, the area A1 of the first heat exchanger 220 on the central portion represents the flow area in which the flow occurs, and the areas A2 and A3 of the first heat exchanger 220 on both edges represent the dead zone area. As shown, the area A1 forms most of the area of the heat exchanger, and the areas A2 and A3 represent a very small area compared to the area A1.

The shroud 320 may be seated on the upper end of the fan support portion 252.

The front end of the shroud 320 may be aligned with the front end of the fan support portion 252, and the rear end of the shroud 320 may be located in the front of the fan support portion 252 rather than the rear of the fan support portion 252.

A space between the rear end of the fan support portion 252 and the rear end of the shroud 320 may form a discharge port 271 so that the fluid passing through the cover passage 256 flows into the duct 30.

The discharge port 271 may be connected to the duct 30.

The passage guide 255 may be disposed in the discharge port 271.

An outlet portion 58, through which the fluid discharged from the first fan 310 is discharged, may be formed in the partition wall 50. The fan support portion 252 may be inserted into the outlet portion 58.

A direction in which the fluid in the second storage space 16 flows in the first space 205a may include a direction different from a direction in which the fluid flows in the second space 205b. Therefore, it is possible to reduce the occurrence of the fluidized bed dead zone of the fluid in the inner space of the second storage space 16. The direction in which the fluid in the second storage space 16 flows in the first space 205a may include a direction opposite to the direction in which the fluid flows in the second space 205b.

The storehouse may include an air guide configured to change the flow direction of the fluid passing through the first heat exchanger 220. The air guide may be disposed in the inner space of the second storage space 16, for example, the second space 205b. Therefore, the flow resistance can be reduced while the fluid changes the flow direction.

The air guide may include a first surface and a second surface. A direction in which the fluid in the second storage space 16 flows along the first surface of the air guide may include a direction different from a direction in which the fluid flows along the second surface of the air guide. The first surface of the air guide may be disposed closer to the first heat exchanger 220 than the second surface of the air guide. The second surface of the air guide may be disposed closer to the fluid generator 300 than the first surface of the air guide.

For example, the heat exchange device 100 may further include a guide plate 280 provided between the first heat exchanger 220 and the first fan 310 to define a suction passage of the first fan 310.

The guide plate 280 may be disposed at a position separating the first space 205a from the second space 205b.

The guide plate 280 may be provided between the first heat exchanger 230 and the fan suction portion 253 of the first heat exchanger cover 250.

The guide plate 280 may be provided on the bottom surface of the first heat exchanger cover 250 or the cover plate 290.

The suction passage of the first fan 310 may be defined between the guide plate 280 and the first heat exchanger cover 250.

The guide plate 280 may be provided above the first heat exchanger 220.

The guide plate 280 may be provided below the first fan 310.

The guide plate 280 may extend in the front-and-rear direction and guide the fluid to flow in the front-and-rear direction.

The guide plate 280 may include a plate body 281 defining a through hole 283.

The guide plate 280 may include a plate edge 282 extending downward from the edge of the plate body 281. A first coupling hole 282a may be formed in the plate edge 282, and the first coupling hole 282 may be coupled to a second coupling hole 212a formed in the inner surface of the inner case 212 by a predetermined coupling member.

The through hole 283 may guide the fluid passing through the first heat exchanger 220 toward the suction side of the first fan 310. The through hole 283 may communicate with the first space 205a and the second space 205b.

The fluid may flow backward while passing through the first heat exchanger 220. At this time, the fluid may be guided by the bottom surface of the guide plate 280. This flow is defined as a "first flow".

The through hole 283 may be formed adjacent to the rear end of the first heat exchanger 220.

Therefore, the fluid passing through the first heat exchanger 220 may flow to the upper side of the guide plate 280 through the through hole 283 and may flow forward toward the center of the first fan 310. At this time, the fluid may be guided by the top surface of the guide plate 280. This flow is defined as a "second flow".

The second flow may form a flow direction opposite to that of the first flow.

The fluid reaching the center of the first fan 310 is sucked in the axial direction (upward) of the first fan 310 through the fan suction portion 253. This flow is defined as a "third flow".

The fluid sucked into the first fan 310 changes to the radial direction and flows backward, and may be introduced into the duct 30 through the discharge port 271. This flow is defined as a "fourth flow".

As such, the fluid passing through the first heat exchanger 220 may form a curved passage while forming the first to third flows. Due to the curved flow, the length of the passage is formed to be long compared to the width of the first heat exchanger 220 in the left-and-right direction. Therefore, the area of the fluid dead zone on the left and right sides of the first heat exchanger 220 may be reduced. Accordingly, the heat exchange area of the first heat exchanger can be fully utilized.

The direction in which the fluid in the second storage space 16 flows along the first surface of the air guide may include a portion greater than 90 degrees with respect to the direction in which the fluid flows along the second surface of the air guide.

For example, the fluid discharged from the first fan 310 may flow in the radial direction. In this case, the fluid may be guided along the cover body 251.

The direction of the fluid may be changed by the fan support portion 252, so that the fluid flows upward. That is, after passing through the first fan 310, the fluid may form a curved flow before flowing into the duct 30.

An extension line (ℓ3) extending along the surface of the cover body 251 and an extension line (ℓ4) extending along the surface of the fan support portion 252 may form an angle θ1 greater than 90 degrees.

A passage through which water formed on the surface of the first heat exchanger 220 is discharged to the outside may be provided in the first space 205a.

For example, a drain hole 208, through which the fluid is discharged, is defined in the bottom surface of the heat exchanger case 210. The drain hole 208 may be formed by the second hole defining portion 208b formed on the bottom surface of the outer case 211 and the first hole defining portion 208a of the inner case 212.

The bottom surface of the heat exchanger case 210 may be inclined downward toward the drain hole 208 so as to facilitate drainage through the drain hole 208.

The heat exchange device 100 may form a defrost water hole configured to discharge condensed water generated in the fan assembly 300.

The first heat exchanger cover 250 may include a first defrost water hole 254a formed at a position where a portion of the cover body 251

The first defrost water hole 254a may be located in front of the central axis of the first fan 310.

The first heat exchanger cover 250 may include a second defrost water hole 254b formed in the fan support portion 252.

The guide plate 280 may form a third defrost water hole 284. The third defrost water hole 284 may be formed at a lower position than the first defrost water hole 284 and the second defrost water hole 284.

The third defrost water hole 284 may be formed in the front portion of the guide plate 280.

The guide plate 280 may be inclined downward toward the third defrost water hole 284 so as to facilitate drainage through the third defrost water hole 284.

The fluid discharged through the first and second

defrost water holes

254a and 254b may be collected inside the heat exchanger case 200 through the third defrost water hole 284 and may be drained through the drain hole 208.

The first fan 310 may be inclined downward toward the first and second defrost water holes 254a so that the fluid generated in the fan assembly 300 is easily drained through the first and second

defrost water holes

254a and 254b.

Although not shown, a defrost heater may be provided inside the heat exchanger case 200. For example, the defrost heater may be disposed below the first heat exchanger 220.

The flow of the fluid circulating in the first storage space 15 and the heat exchange device 100 according to the driving of the first fan 310 will be briefly described.

When the first fan 310 is driven, the fluid in the first storage space 15 is introduced into the suction connector 260 through the suction port 261 and flows into the heat exchanger case 200 through the case duct 215.

The fluid may be introduced into the first heat exchanger 220 through the front end portion of the first heat exchanger 220, may exchange heat with the first heat exchanger 220 while flowing backward, and may be discharged through the rear end portion of the first heat exchanger 220.

The fluid discharged from the first heat exchanger 220 flows toward the upper side of the guide plate 280 through the through hole 283, flows forward, and is sucked in the axial direction of the first fan 310.

The fluid discharged in the radial direction of the first fan 310 is discharged from the heat exchange device 100 through the discharge port 271 and is introduced into the duct 30. The fluid in the duct 30 may be supplied to the first storage space 15 through the duct discharge hole 35.

After the second storage space 16 is coupled to the first storage space 15, the second passage may be disposed such that the first passage and the second passage are connected through the inner space of the second storage space 15.

The connector inlet hole 476a of the discharge connector 470 may be understood as defining the "discharge hole" from the viewpoint of the second storage space 16. The connector discharge hole 476b of the discharge connector 470 may be understood as defining the "inlet hole" from the viewpoint of the first passage of the first storage space 15.

The second storage space 16 may include a first space as an inner space and a second space disposed adjacent to the first space. The first space may be disposed adjacent to the second space in the X-axis direction.

For example, the heat exchanger case 400 may form a case accommodation portion 405 including a first space 405a and a second space 405b. The first space 405a may be disposed adjacent to the second space 405b in the X-axis direction.

The air guide may constitute a portion of the surface of the second wall. For example, the inner surface of the heat exchanger case 610 may constitute at least a portion of the second wall, and the inner surface of the heat exchanger case 400 may constitute the air guide.

The air guide may include a first surface and a second surface. A direction in which the fluid in the second storage space 16 flows along the first surface of the air guide may include a direction different from a direction in which the fluid flows along the second surface of the air guide. The first surface of the air guide may be disposed closer to the first heat exchanger 630 than the second surface of the air guide. The second surface of the air guide may be disposed closer to the fluid generator than the first surface of the air guide.

For example, the first surface of the air guide may include a lower surface 614a among the inner surfaces of the heat exchanger case 610, and the second surface of the air guide may include a side surface 614b among the inner surfaces of the heat exchanger case 610.

The first surface of the air guide may be disposed to face the second space 605b, and the second surface of the air guide may be disposed to face the second space 605b.

Referring to FIG. 22, a second storage space 16 according to a fifth embodiment of the present disclosure may include a heat exchanger case 710.

The inner space of the heat exchanger case 710 may form a case accommodation portion 705.

A case inlet portion 715, through which a fluid in the second storage space 16 is introduced, is formed in the heat exchanger case 710.

The case inlet portion 715 may be defined by being recessed from the surface of the heat exchanger case 710. For example, the case inlet portion 715 may be recessed from the upper surface of the first heat exchanger case 710.

The heat exchanger case 710 may define an inner passage through which the fluid flows. The inner passage may be configured to be recessed downward from the case inlet portion 715 and bent toward the case accommodation portion 705.

The inner passage may be connected to the inner surface of the heat exchanger case 710 and may communicate with the case accommodation portion 705.

The heat exchanger case 710 may further include a case wall 713 separating the case accommodation portion 705 and the inner passage. The case wall 713 may be in contact with the bottom surface of the partition wall 50.

The fluid in the first storage space 15 may pass through the inlet portion 51, flow into the inner passage through the case inlet portion 715, and then flow into the case accommodation portion 705.

For example, the heat exchanger case 710 may form a case accommodation portion 705 including a first space 705a and a second space 705b. The first space 705a may be disposed adjacent to the second space 705b in the X-axis direction.

The second space 705b may be defined as a space in which the first heat exchanger 730 is disposed less than the first space 705a. The first heat exchanger 730 may not be disposed in the second space 705b.

The first space 705a may be defined as a space in which the first heat exchanger 730 is disposed closer to the first heat exchanger 220 than the second space 705b.

At least a part of the first heat exchanger 730 may be disposed in the first space 705a.

The second space 705b may be defined as a space disposed closer to the fluid generator than the first space 705a.

For example, the fluid generator may include a fan assembly 750, and the fan assembly 750 may include a first fan 751 and a shroud 753 accommodating the first fan 751.

The fan assembly 750 may be provided inside the second storage space 16 or inside the duct 30.

The fluid in the second storage space 16 may pass through the first space 705a and then flow toward the second space 705b. The fluid in the second storage space 16 may pass through the second space 705b and may flow toward the fluid generator through the opened outlet portion 58 of the partition wall 50.

A direction in which the fluid in the second storage space 16 flows in the first space 705a may include a direction different from a direction in which the fluid flows in the second space 705b. Therefore, it is possible to reduce the occurrence of the fluidized bed dead zone of the fluid in the inner space of the second storage space 16.

The storehouse may include a passage provided in the first space 705a and through which water formed on the surface of the first heat exchanger 630 is discharged to the outside. For example, a drain hole 718 may be defined in the first space 705a.

The passage may be provided at a lower portion of the first space 705a. For example, the drain hole 718 may be provided below the first space 705a.

A fluid generator may be disposed above the second space 705b. For example, the fluid generator may include the first fan 751.

The fluid in the second storage space 16 may pass through the first storage space 15 and then flow toward the first space 705a. Therefore, heat exchange efficiency through the first heat exchanger 730 may be improved.

For example, the air guide may be disposed in the second space 705b. Therefore, the flow resistance can be reduced while the fluid changes the flow direction. The air guide may constitute a portion of the surface of the second wall. For example, the inner surface of the heat exchanger case 610 may constitute at least a portion of the second wall, and the inner surface of the heat exchanger case 400 may constitute the air guide.

The air guide may include a first surface and a second surface. A direction in which the fluid in the second storage space 16 flows along the first surface of the air guide may include a direction different from a direction in which the fluid flows along the second surface of the air guide. The first surface of the air guide may be disposed closer to the first heat exchanger 730 than the second surface of the air guide. The second surface of the air guide may be disposed closer to the fluid generator than the first surface of the air guide.

For example, the first surface of the air guide may include a lower surface 714a among the inner surfaces of the heat exchanger case 710, and the second surface of the air guide may include a side surface 714b among the inner surfaces of the heat exchanger case 710.

The first surface of the air guide may be disposed to face the first space 705a, and the second surface of the air guide may be disposed to face the second space 705b.

With this configuration, heat exchange efficiency through the first heat exchanger 730 can be improved and flow performance can be improved.

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.
