Description

Storage room

Technical Field

The present disclosure relates to a storage compartment.

Background

The storage compartment may include a storage space for storing the articles. Examples of the storage chamber may include a refrigerator.

A refrigerator is a device that cools objects to be cooled (e.g., foods, medicines, and cosmetics) (hereinafter, referred to as foods for convenience) or stores foods at low temperature to prevent spoilage and deterioration. The refrigerator includes a storage space to store food and a refrigerating cycle part to cool the storage space.

The refrigeration cycle 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 open front side. Such a refrigerator may include a cool air discharge duct provided at the inside of the inner case to divide 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 rear of the cold air discharge duct. The evaporator and the evaporation fan may be disposed in the heat exchange space.

The refrigerator may have a separate machine space defined outside the inner case. The compressor, condenser and 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 by means of refrigerant pipes.

The storage space may be provided with a drawer that is extractable. A plurality of drawers may be provided in a vertical direction.

However, the refrigerator according to the related art as described above has the following problems.

First, a compressor in a machine space and an evaporator in an inner case are disposed in a space separated from each other and connected to each other by a refrigerant pipe. Therefore, when it is necessary to repair the refrigeration cycle, the food stored in the refrigerator is taken out to check and repair the malfunction, which is inconvenient.

Second, since the evaporator must be integrally formed inside the refrigerator body and the evaporator must be fixed to the refrigerator body by welding or the like, there is an inconvenience in manufacturing the refrigerator. In addition, when the evaporator is defrosted, heat exchange with the storage space increases the internal temperature of the refrigerator.

Third, since the heat exchange space is provided at the rear of the storage space, the width of the rear wall of the refrigerator body in the front-rear direction may increase with the size of the heat exchange space. Accordingly, the volume of the storage space is also reduced accordingly.

In order to solve these problems, a refrigerator including a cooling module integrally constructing a heat absorbing part and a heat dissipating part has been proposed.

As another example, the hook means may be arranged on the heat exchanger case 200 or the storage chamber body 10 such that the heat exchanger case 200 is caught on the storage chamber body 10.

The fluid in the first storage space 15 may be introduced into the interior of the second storage space, for example, the interior 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. During passage through the first heat exchanger 220, fluid may flow from the front to the back 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 may be formed through which fluid flows inside or outside the tray 130 via a space defined between the tray 130 and the second wall.

The fluid fw generated inside the second storage space 16 (e.g., the heat exchanger case 200) may be collected into the tray 130 through the drain hole 208.

Hereinafter, other embodiments of the present disclosure will be described. Since these embodiments are different from the first embodiment in the tray and tray peripheral structure, these differences will be mainly described. The same description and reference numerals as those of the first embodiment apply equally to the same components as those of the first embodiment.

Fig. 17 is a view showing the construction of a tray according to a second embodiment of the present disclosure, and fig. 18 is an enlarged view of a portion "a" of fig. 17.

Referring to fig. 17 and 18, the tray 130 according to the second embodiment of the present disclosure may include a tray body 131 defining a bottom surface, and a storage wall 132 protruding upward from the tray body 131 and configured to block a flow of collected water or water vapor to store the collected water or water vapor.

The storage wall 132 may be disposed around the tray 130.

The reservoir wall 132 may include a through-hole therethrough.

The storage wall 132 may include a first portion 132a having a first height H1', and a second portion 132b having a second height H2' that is higher than the first height H1 '.

The tray recessed portion 136 may be defined by a first portion 132a and a second portion 132b.

The upper end of the support wall 133 may support the tray body 131.

Due to the presence of the support wall 133, the heat exchanger case 200 is not immersed in the condensed water collected in the tray 130.

Due to the presence of the support wall 133, the distance of upward movement is not great when the heat exchanger housing 200 is coupled to the partition wall 50. Accordingly, the heat exchanger case 200 can be stably coupled.

Since the detailed construction of the support wall 133 is the same as that of the first embodiment, redundant description is omitted.

The tray 130 may include a bottom surface and a partition wall protruding from the bottom surface and dividing an inner space of the tray 130 into two or more spaces.

The partition wall may be provided inside the tray. The partition wall may include a portion having a height lower than the second portion of the storage wall. The partition wall may include a portion having a height lower than the first portion of the storage wall.

To facilitate closing of the door 20, the storage compartment body 10 may be provided to be slightly inclined rearward. In order to prevent the fluid stored in the tray 130 from overflowing to the outside due to the inclined arrangement of the storage chamber body 10, the tray 130 may include a tray partition wall 134 for reducing the fluidity of the fluid.

Tray dividing wall 134 may be configured to bisect the fluid collection surface of tray body 131.

The tray partition wall 134 may be provided to protrude upward from the fluid collecting surface of the tray body 131.

The tray partition 134 may have, for example, a bar shape or a plate shape.

Two sides of the tray dividing wall 134 may be connected to the storage wall 132.

The storage wall 132 may be provided at a corner of the tray body 131, and may include a plurality of walls.

The tray partition wall 134 may be configured to connect two walls provided at both sides of the tray body 131 among the plurality of walls. For example, one end of the tray partition wall 134 may be connected to a first wall provided at one side of the tray body 131, and the other end of the tray partition wall 134 may be connected to a second wall provided at the other side of the tray body 131.

The first and second walls may constitute edge portions facing each other.

Due to the configuration in which both sides of the tray dividing wall 134 are connected to the storage wall 132, the fluid collecting space of the tray 130 may be divided equally by the tray dividing wall 134. The fluid collection space bisected by the tray partition wall 134 may be defined as a first fluid collection space 130a and a second fluid collection space 130b.

The first fluid collection space 130a may be a space defined by one of the tray partition wall 134 and the storage wall 132. The second fluid collection space 130b may be a space defined by the tray partition wall 134 and the other one of the storage walls 132.

Even if the storage chamber body 10 is tilted such that the tray 130 is unbalanced, the fluid stored in the first fluid collection space 130a does not easily flow into the second fluid collection space 130b due to the tray partition wall 134. Also, the fluid stored in the second fluid collection space 130b does not easily flow into the first fluid collection space 130a through the tray partition wall 134.

That is, since excessively easy flow in the tray 130 is prevented, fluid can be prevented from overflowing to the outside of the tray 130.

The height H3 of the tray partition 134 may be formed to be smaller than the height of the second portion 132b of the storage wall 132.

The height H3 of the tray partition 134 may be formed to be smaller than the height of the first portion 132a of the storage wall 132.

The fluid stored in the first fluid collection space 130a may flow into the second fluid collection space 130b across the tray partition wall 134. The fluid stored in the second fluid collection space 130b may flow into the first fluid collection space 130a across the tray partition wall 134.

By arranging the support wall 133 and the tray partition wall 134 to intersect each other, it is possible to prevent the fluid stored in the tray 130 from overflowing to the outside of the tray 130. That is, the support wall 133 and the tray partition wall 134 may serve as a resistance body to block the flow of the fluid overflowing to the outside of the tray 130.

The support wall 133 may include a portion having a height higher than that of the tray partition wall 134.

The refrigerant tube 138 may be disposed on the fluid collection surface of the tray 130. The refrigerant tube 138 may be disposed adjacent to the fluid collection surface of the tray 130 or may be disposed in contact with the fluid collection surface of the tray 130.

The refrigerant pipe 138 extends from the space at one side of the tray 130 to the upper side of the tray 130, and may be drawn out into the space at the other side of the tray 130.

The refrigerant tube 138 may be provided to have a curved or circular shape so as to be relatively longitudinally formed in the limited-volume tray 130.

The refrigerant tube 138 may include a refrigerant tube through which a high temperature refrigerant flows.

For example, the refrigerant tube 138 may include a discharge line of the compressor 121. The refrigerant pipe 138 may include a first side portion 138a connected to a discharge side of the compressor 121 and a second side portion 138b connected to an inlet side of the second heat exchanger 123.

As another example, the refrigerant tube 138 may include an outlet tube of the second heat exchanger 123.

In this way, since the refrigerant pipe through which the high temperature fluid flows is provided in the tray 130, condensed water collected in the tray 130 can be easily evaporated.
