Description

Refrigerator body module, refrigerator and housing for refrigerator

Technical Field

The utility model belongs to the technical field of refrigerators, and particularly provides a refrigerator body module of a refrigerator, the refrigerator and a housing for the refrigerator.

The whole shape, the number of internal compartments and the volume of the internal compartments of the existing refrigerator of the same series are the same, and the refrigerators of different models are often different only in color and the material of the shell. The existing refrigerator cannot meet the demands of wide users due to different families, different decoration styles and different favorites of different users. And manufacturers cannot provide customized refrigerators for users according to the demands of the users. The refrigerator is characterized in that the existing refrigerator generally integrates a refrigerating system on the refrigerator body of the refrigerator, so that manufacturers need to redesign the structure and layout of the refrigerator according to the needs of users, and more molds are needed to be newly opened, so that the production cost of the refrigerator is higher, and the production period is longer.

In order to overcome the above problems, the prior art proposes a modular refrigerator. Specifically, the refrigerator is designed into two independent modules, namely a refrigerator body module and a refrigerating module. The refrigerating module can adapt to various different box modules so as to assemble the refrigerating module and the corresponding box modules together according to the custom-made demands of users.

In order to realize the refrigeration of the refrigeration module to the box module, cold air in the refrigeration module needs to be introduced into the box module. In order to align the air paths on the refrigeration and tank modules, it is necessary to closely abut the refrigeration and tank modules together. The extrusion of the box module to the refrigeration module is extremely easy to cause deformation (especially left side edge and right side edge) of the edge contacted with the refrigeration module on the box module, and the tightness of the air path between the box module and the refrigeration module is affected. The technical problem is an important limiting factor for preventing the refrigerator from realizing modularization, and the problem needs to be solved.

Air in the second storage compartment 1012 flows from the open mouth of the second storage compartment 1012 and the second return air passage to the refrigeration module 200.

Further, although not shown, in some embodiments of the utility model, the case module 100 further includes a first door corresponding to the first storage compartment 1011 and a second door corresponding to the second storage compartment 1012. The first door is used for shielding the first storage room 1011 to prevent external air from entering the first storage room 1011. The second door is used for shielding the second storage compartment 1012 to prevent external air from entering the second storage compartment 1012; the second door also serves to shield the top of the refrigeration module 200, and in particular, the first return air inlet 21021 of the refrigeration module 200 (as shown in fig. 9). Further, the inner side of the second door is provided with a sink having a portion aligned with and communicating with the second storage compartment 1012 and a portion aligned with and communicating with the first return air inlet 21021 of the refrigeration module 200, such that the tank module 100 defines a second return air passage through the sink, thereby allowing air in the second storage compartment 1012 to flow to the refrigeration module 200 through the sink.

In addition, in other embodiments of the present utility model, a person skilled in the art may also provide a channel (as a second return air channel) on the second door, and align and communicate one end of the channel with the second storage compartment 1012, and align and communicate the other end of the channel with the first return air inlet 21021 of the refrigeration module 200, as desired.

As shown in fig. 2 to 4, in some embodiments of the present utility model, the tank module 100 includes a first liner 110, a second liner 120, an air supply duct 130, an air return duct 140, a casing 150, and a housing 160. Wherein, a first storage compartment 1011 is formed in the first liner 110, and a second storage compartment 1012 is formed in the second liner 120. In other words, the first storage compartment 1011 is defined by the first liner 110, and the second storage compartment 1012 is defined by the second liner 120. An air supply channel 1301 is defined in the air supply pipe 130, and the air supply channel 1301 is respectively communicated with the first storage compartment 1011 and the second storage compartment 1012, so that the box module 100 receives cold air from the refrigeration module 200 through the air supply channel 1301 and delivers the cold air to the first storage compartment 1011 and the second storage compartment 1012.

As shown in fig. 4, a first return air channel 1401 (shown by a dotted line in fig. 4) is formed in the return air duct 140, and a top end of the first return air channel 1401 is communicated with a first air outlet 10111, or the first air outlet 10111 forms an inlet of the first return air channel 1401; so that the tank module 100 delivers air in the first storage compartment 1011 to the refrigeration module 200 through the first return air channel 1401.

Furthermore, in still other embodiments of the present utility model, one skilled in the art may arrange the storage compartments 101 in any other feasible number, such as one, three, five, six, etc., as desired. Those skilled in the art may also include other numbers of bladders, such as one, three, four, etc., as desired. For example, the housing module 100 may include only one liner and the liner may define one or more storage compartments. When the liner defines only one storage compartment, the storage compartment may be configured to deliver air therein to the refrigeration module 200 in the manner of the first storage compartment 1011 or the second storage compartment 1012 as described above. When the liner defines a plurality of storage compartments, the bottom storage compartment delivers air therein to the refrigeration module 200 in the manner of the second storage compartment 1012 as described above; the other storage compartments adopt the first storage compartment 1011 as described above to convey the air therein to the refrigeration module 200, and each storage compartment may correspond to one return air duct 140 (each return air duct 140 corresponds to one second return air port 21022 (as shown in fig. 9)) respectively, or may share one return air duct 140.

With continued reference to fig. 5-8, the housing 150 includes a left sloping plate 151 disposed between its left side plate and its top plate, a rear sloping plate 152 disposed between its rear side plate and its top plate, and a right sloping plate 153 disposed between its right side plate and its top plate. The rear inclined plate 152 is provided with a rear hole 1521 penetrating therethrough, and the rear hole 1521 is connected to the air supply duct 1301. Specifically, the bottom end of the air supply duct 130 is inserted into the rear hole 1521 or is docked with the rear hole 1521, thereby realizing the connection of the rear hole 1521 with the air supply channel 1301. The right inclined plate 153 is provided with a side hole 1531 penetrating therethrough, and the side hole 1531 is connected with the return air passage. Specifically, the bottom end of the return air duct 140 is inserted into the side hole 1531 or docked with the side hole 1531, thereby enabling connection of the side hole 1531 with the first return air channel 1401.

As shown in fig. 1-3, all of the liners and shells 150 on the tank module 100 are disposed within the housing 160. Further, the cover 150 is connected to the housing 160 through its left side plate and its right side plate.

A left outer bevel 2121 is provided at the junction of the left side plate of the housing 210 and the top plate of the housing 210, and the left outer bevel 2121 is parallel to and abuts against the left inner bevel 1512 of the housing 150. A right outer inclined surface 2122 is provided at a junction between the right side plate of the housing 210 and the top plate of the housing 210, and the right outer inclined surface 2122 abuts against a right inner inclined surface 1532 of the casing 150. The second return air inlet 21022 is formed in the right outer ramp 2122. The rear outer inclined surface 213 is provided at the junction between the rear side plate of the housing 210 and the top plate of the housing 210, the rear outer inclined surface 213 is parallel to and abuts against the rear inner inclined surface 1522 of the casing 150, and the air outlet 2101 is formed in the center of the rear outer inclined surface 213.

As can be seen from fig. 9, the first air return opening 21021 is a strip-shaped opening extending transversely, the second air return opening 21022 is a strip-shaped opening extending front and back, and the air supply opening 2101 is a rectangular opening extending transversely. In addition, any one of the first return air inlet 21021, the second return air inlet 21022 and the air supply outlet 2101 can be provided as any other type of opening, such as a circular opening, a square opening, etc., as required by those skilled in the art.

As shown in fig. 1 and 2, in the assembled state of the refrigerator, the left outer inclined surface 2121 is parallel to and abuts against the left inner inclined surface 1512, the right outer inclined surface 2122 is parallel to and abuts against the right inner inclined surface 1532, and the rear outer inclined surface 213 is parallel to and abuts against the rear inner inclined surface 1522. The top plate of the housing 210 also abuts the top plate of the enclosure 150 so that the housing 210 carries a substantial portion of the weight of the tank module 100 through its top plate, avoiding excessive pressure from the tank module 100 on the three sets of mating ramps. Compressible structures such as foam and foam plates are also respectively arranged between the left outer inclined surface 2121 and the left inner inclined surface 1512, between the right outer inclined surface 2122 and the right inner inclined surface 1532, between the rear outer inclined surface 213 and the rear inner inclined surface 1522 and between the top plate of the shell 210 and the top plate of the housing 150, so that the two opposite sides are abutted together by the compressible structures to be attached more tightly, thereby improving the stability and the tightness of the fixation between the tank module 100 and the refrigeration module 200.

As will be appreciated by those skilled in the art, the abutment between the left outer ramp 2121 and the left inner ramp 1512, the abutment between the right outer ramp 2122 and the right inner ramp 1532, and the abutment between the rear outer ramp 213 and the rear inner ramp 1522 results in a greater area of contact at the line where the opposite edges of the surface contact are in contact, less pressure, and less deformation. At the same time, the component forces received by the left outer inclined surface 2121 and the left inner inclined surface 1512, the right outer inclined surface 2122 and the right inner inclined surface 1532, and the rear outer inclined surface 213 and the rear inner inclined surface 1522 in the vertical direction are also reduced. The force is the weight of the food material within the tank module 100. In particular, the angles between the outer inclined surface 2121, the left inner inclined surface 1512, the right outer inclined surface 2122 and the right inner inclined surface 1532 and the horizontal plane are all larger than 45 degrees, so that the component force applied to the four inclined surfaces in the vertical direction is effectively reduced.

Optionally, in some embodiments of the present utility model, the angle between the rear outer inclined surface 213 and the horizontal plane is smaller than 45 °, so as to reduce the pressure applied to the rear outer inclined surface 213, and at the same time, enable the air supply port 2101 to blow the air flow obliquely upward, and make the air flow upward as much as possible.

As shown in fig. 2 and 3, in the assembled state of the refrigerator, the air supply port 2101 is abutted with the air supply pipeline 130 on the box module 100, so that the refrigerating module 200 supplies air to the air supply pipeline 130 through the air supply port 2101, and the air supply pipeline 130 supplies cold air received by the refrigerating module to the storage compartment 101. The first return air inlet 21021 and the second storage compartment 1012 are both positioned on the front side of the refrigerator, and both are in communication through a sink or channel formed in the second door (as described above) such that the refrigeration module 200 receives air from the second storage compartment 1012 through the first return air inlet 21021.

In other words, if the press house 2103, the heat dissipation air intake passage 2105 and the heat dissipation air outlet passage 2106 are regarded as one whole, the projection of the refrigerating compartment 2104 on the horizontal plane is located inside the projection on the one whole horizontal plane.

As shown in fig. 11 and 12, the supply-air port 2101, the first return air port 21021 and the second return air port 21022 are respectively communicated with the refrigerating compartment 2104.

Most of the tube sections of the capillary tube 225 and the return air tube 227 are located outside the press bin 2103 and the refrigeration compartment 2104. Alternatively, one skilled in the art may also dispose all of the capillaries 225 and/or the return air tubes 227 outside of the press bin 2103 and refrigeration compartment 2104 as desired.

A front gap 21072 is formed between the bottom of the front plate of the refrigerating compartment 2104 and the outer plate of the casing 210 adjacent thereto, and the front gap 21072 is filled with a heat insulating material (e.g., a foaming agent or heat insulating cotton). A longitudinal gap 21073 is formed between the left and right side plates of the refrigerating compartment 2104 and the outer side plates of the respective adjacent housings 210, and the longitudinal gap 21073 is filled with a heat insulating material (e.g., a foaming agent or heat insulating cotton). Those skilled in the art will appreciate that the insulating material outside the refrigerated compartment 2104 is effective to insulate the refrigerated compartment 2104 from cold leakage.

Further, the top plates of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are parallel to the bottom plate of the refrigeration compartment 2104, so that the heat insulation materials in the transverse gap 21071, the front gap 21072 and the longitudinal gap 21073 are uniformly filled with the heat insulation materials with the same thickness, and the refrigeration compartment 2104 is uniformly insulated.

Optionally, the portions of the capillary tube 225 and the air return tube 227 outside the press bin 2103 and the refrigeration compartment 2104 are disposed in the longitudinal gap 21073 and are surrounded by insulation. Preferably, capillary tube 225 and return air tube 227 abut to allow the two to exchange heat. Further, since the temperature of the heat dissipation air intake passage 2105 is lower than the temperature of the heat dissipation air output passage 2106, the capillary tube 225 and the air return tube 227 are preferably arranged in one of the two longitudinal gaps 21073 close to the heat dissipation air intake passage 2105.

As shown in fig. 18 and 19, the refrigeration module 200 further includes a platen 260 disposed between the evaporator 226 and the ceiling of the refrigeration compartment 2104, the platen 260 being used to compress the evaporator 226 against the floor of the refrigeration compartment 2104, thereby securing the evaporator 226 obliquely within the refrigeration compartment 2104.

In some embodiments of the present utility model, the evaporator 226 is disposed obliquely upward in a front-to-rear direction, and the included angle of the evaporator 226 with the horizontal plane ranges from 8 ° to 45 °, such as 8 °, 12 °, 15 °, 20 °, 30 °, 45 °, and so on.

Furthermore, in other embodiments of the present utility model, the evaporator 226 may be placed horizontally, as desired, with the projected area of the evaporator 226 on a horizontal plane being larger than the projected area of the evaporator on a vertical plane.

With continued reference to fig. 18 and 19, in some embodiments of the utility model, the floor of the refrigerated compartment 2104 is provided with a drain hole 2108 below the front of the evaporator 226. The refrigeration module 200 further includes a drain pipe 270 communicating with the drain hole 2108 and extending from above down into the evaporation pan 250 so that the drain pipe 270 can rapidly drain the defrost water in the refrigeration compartment 2104 into the evaporation pan 250.

With continued reference to fig. 18 and 19, the blower fan 240 is located between the evaporator 226 and the air supply port 2101 in the air flow path, and both the evaporator 226 and the blower fan 240 are disposed obliquely within the refrigeration compartment 2104.

As shown in fig. 18, the floor of the refrigerating compartment 2104 includes, on the rear side of the drain hole 2108, an evaporator support section 21041 and a blower support section 21042 extending obliquely rearward and upward, and the inclination angle of the blower support section 21042 is larger than that of the evaporator support section 21041 so that the inclination angle of the blower 240 is larger than that of the evaporator 226. Preferably, the blower fan 240 is a centrifugal fan. The top surface of the centrifugal fan is aligned with the rotation axis of the impeller and the distance between the top plate of the refrigerating chamber 2104 is not less than 30 mm, so that the wind resistance of the centrifugal fan during air suction is reduced.

Wherein the pitch is a distance in the direction in which the axis of the impeller extends.

In addition, the blower fan 240 may be any other possible fan, such as a cross-flow fan, an axial flow fan, etc., as desired by those skilled in the art.

As shown in fig. 20-22, in some embodiments of the utility model, the housing 210 further includes a wind-guiding member 280, the wind-guiding member 280 being configured to communicate the second return air inlet 21022 with the refrigerated compartment 2104. Specifically, the air guide members 280 extend through the longitudinal gap 21073, and the air outlet ends of the air guide members 280 extend to the front side of the evaporator 226.

In some embodiments of the utility model, the second return air inlet 21022 may be in communication with the air inlet end of the air guide member 280, or may be formed on the air inlet end of the air guide member 280.

As shown in fig. 21 and 22, the air guide member 280 includes a lateral opening portion 281 and a longitudinal opening portion 282, and an air intake opening is provided at the top of the lateral opening portion 281, and the opening direction of the air intake opening is inclined upward in the lateral direction (the left-right direction of the refrigeration module 200). The air inlet is also provided as a rectangular or strip-shaped opening extending in the front-rear direction. An air outlet is provided at one side of the longitudinal opening 282 in the lateral direction, and is provided as a rectangular opening or a strip-shaped opening extending in the vertical direction. The air outlet of the air guide 280 extends to the front side of the evaporator 226 so that the air flow blown out of the air guide 280 is entirely blown toward the front side of the evaporator 226.

As shown in fig. 14 and 15, in the left-right direction of the refrigeration module 200, the compressor 221, the heat radiation fan 230, and the condenser 223 are sequentially arranged between the heat radiation air outlet passage 2106 and the heat radiation air inlet passage 2105, and the heat radiation fan 230 and the condenser 223 are disposed in close proximity to reduce the size in the lateral direction of the refrigeration module 200.

Optionally, the refrigeration module 200 further includes a fixed housing 201 disposed within the press bin 2103, and the heat dissipation fan 230 and the condenser 223 are fixedly connected to the fixed housing 201. Further alternatively, at least a part of at least one of the heat radiation fan 230 and the condenser 223 is embedded in the stationary case 201. Preferably, at least a portion of each of the heat radiation fan 230 and the condenser 223 is embedded in the fixing case 201 such that the air flow passing through the heat radiation fan 230 entirely passes through the condenser 223, thereby improving the heat radiation efficiency of the heat radiation fan 230 to the condenser 223.

As can be seen in fig. 14 and 16, the bottom plates of the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are respectively provided with a gap between the bottom plates and a bearing surface (such as a ground or a floor).

As shown in fig. 14 to 17, the heat dissipation air intake passage 2105 includes a plurality of front air intake openings 21051 formed on a front side plate of the housing 210 so that outside air can enter the heat dissipation air intake passage 2105 from the plurality of front air intake openings 21051. Further, the heat dissipation air intake passage 2105 further includes a plurality of bottom side air inlets 21052 formed on a bottom plate of the heat dissipation air intake passage 2105 so that outside air can enter the heat dissipation air intake passage 2105 through gaps below the heat dissipation air intake passage 2105 and the plurality of bottom side air inlets 21052.

As will be appreciated by those skilled in the art, since the heat dissipation air intake duct 2105 has both the plurality of front air inlets 21051 located at the front side thereof and the plurality of bottom air inlets 21052 located at the bottom side thereof, the air intake capability of the heat dissipation air intake duct 2105 is improved and the wind resistance is reduced. Not only avoiding the unsmooth air intake caused by the limitation of the area of the front side plate of the heat dissipation air intake channel 2105 when the heat dissipation air intake channel 2105 is only provided with a plurality of front air intakes 21051; it is also avoided that the heat dissipation air intake channel 2105 has only a plurality of bottom side air intake holes 21052, and impurities such as dust, flock and the like accumulate at the bottom side air intake holes 21052, so that the bottom side air intake holes 21052 are blocked, and further, the heat dissipation air intake channel 2105 cannot obtain enough air.

With continued reference to fig. 14 to 17, the heat dissipation air outlet channel 2106 includes a plurality of front air outlets 21061 formed on a front side plate of the housing 210 so that the hot air in the heat dissipation air inlet channel 2105 can flow out from the plurality of front air outlets 21061 to the outside. Optionally, the heat dissipation air outlet channel 2106 includes a plurality of bottom side air outlets (not shown) formed in a bottom plate thereof.

As shown in fig. 16, the housing 210 further includes a wind deflector 215 provided at the bottom side of the bottom plate of the press magazine 2103, the wind deflector 215 serving to prevent the bottom side air intake 21052 from sucking in the hot air blown out from the front air outlet 21061.

With continued reference to fig. 14-16, the bottom plate of the press bin 2103 is provided with a plurality of bin bottom air inlets 21031 on the windward side of the condenser 223, and the bottom plate of the press bin 2103 is provided with a plurality of bin bottom air outlets 21032 on the side of the heat dissipation fan 230 away from the condenser 223. And the plurality of bottom side air inlets 21052 and the plurality of bin bottom air inlets 21031 are positioned on one side of the wind deflector 215 and the plurality of bin bottom air outlets 21032 are positioned on the other side of the wind deflector 215. Based on this, it will be appreciated by those skilled in the art that ambient air can also enter the press cabin 2103 through the cabin bottom air inlet 21031, and that a portion of the hot air in the press cabin 2103 will flow from the cabin bottom air outlet 21032 to the ambient.

As can be seen in fig. 14-16, in some embodiments of the utility model, a portion of the plurality of bin bottom outlets 21032 is located below the compressor 221 and another portion of the plurality of bin bottom outlets 21032 is located on a front side of the compressor 221.

As shown in fig. 14 to 16, 18 and 19, a plurality of bin bottom outlets 21032 located at the front side of the compressor 221 are adjacent to the evaporating dish 250.

It will be appreciated by those skilled in the art that the air flow blocked by the rear side plate of the evaporating dish 250 can be reflected to the plurality of bin bottom outlets 21032 on the front side of the compressor 221, and further flows from the plurality of bin bottom outlets 21032 to the outside (as shown in fig. 18 and 19). This kind of structure is for the structure that evaporation pan 250 rear side does not have storehouse bottom air outlet 21032, can avoid evaporation pan 250 rear side board effectively to the shielding effect of air current, and then avoid the air current to appear the cyclone in evaporation pan 250 rear side board department effectively. Thus, in some embodiments of the present utility model, the blocking effect of the rear side plate of the evaporating dish 250 on the air flow, and the corresponding noise, can be effectively eliminated.

In other embodiments of the utility model, the plurality of bin bottom outlets 21032 may be arranged in any other feasible manner, as desired, such as, for example, arranging the plurality of bin bottom outlets 21032 on the front, right and bottom sides of the compressor 221, or on the front and/or right side of the compressor 221, by a person of ordinary skill in the art.

As shown in fig. 14 and 15, in some embodiments of the present utility model, the structure of the evaporation pan 250 in the horizontal direction is adapted to the structure of the heat dissipation air outlet channel 2106 in the horizontal direction, that is, the opposite sides of the evaporation pan 250 and the heat dissipation air outlet channel 2106 are parallel to each other, so that the evaporation pan 250 can spread the whole heat dissipation air outlet channel 2106 as much as possible, thereby increasing the evaporation area of the evaporation pan 250 and increasing the evaporation rate of water in the evaporation pan 250.

Optionally, the size of the evaporation pan 250 in the front-rear direction is larger than the size of the evaporation pan 250 in the left-right direction, so that the evaporation pan 250 has a sufficient length in the path of the air flow in the heat dissipation air outlet channel 2106, thereby increasing the contact time of the water in the evaporation pan 250 with the air flow and increasing the evaporation rate of the water in the evaporation pan 250.

Further, the width of the front portion of the evaporating dish 250 is gradually reduced from the rear to the front, and the width of the front portion of the heat dissipation air outlet channel 2106 is also gradually reduced from the rear to the front, so that the flow area of the front portion of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow rate of the air flow at the front portion of the evaporating dish 250 is gradually increased, so as to ensure the evaporation rate of the water in the front portion of the evaporating dish 250.

As will be appreciated by those skilled in the art, in the heat dissipation air outlet channel 2106, the air flow just enters the evaporation pan 250, due to the higher temperature, has good heating effect on the water in the evaporation pan 250; but as the air flow gets closer to the front air outlet 21061, the air flow absorbs more and more heat from the water and the temperature gets lower, resulting in a poorer heating effect on the water. By gradually decreasing the width of the evaporation pan 250 and the front portion of the heat dissipation air outlet channel 2106 from back to front, the flow area of the front portion of the heat dissipation air outlet channel 2106 is gradually decreased, and thus the flow rate of the air flow therein is gradually increased, so that the air flow can overcome the influence of low temperature on the water evaporation efficiency at a high flow rate. Thus, in some embodiments of the present utility model, the evaporation efficiency of the air flow in the heat sink outlet channel 2106 to the water in the evaporation pan 250 is improved by gradually decreasing the width of the evaporation pan 250 and the front portion of the heat sink outlet channel 2106 from back to front.

Further, in the front-rear direction of the refrigeration module 200, the distance between the front surface of the evaporating dish 250 and the front side plate of the housing 210 is not less than 5mm, preferably not less than 15mm, to ensure a sufficient gap between the front surface of the evaporating dish 250 and the front side plate of the housing 210, reducing wind resistance thereto to the air flow.

As can be seen from fig. 16 to 18, the front air inlet 21051 and the front air outlet 21061 are each a bar-shaped hole extending in the up-down direction, and the top surface of the front end of the evaporating dish 250 is located at the middle upper portion of the bar-shaped hole in the vertical direction. That is, in the up-down direction of the refrigeration module 200, the tip of the front side plate of the evaporating dish 250 is located at the upper middle portion of the front air outlet 21061 to ensure that part of the air flow can be blown out from the front air outlet 21061 in the horizontal direction.

Further, in the up-down direction of the refrigeration module 200, the minimum distance between the top surface of the evaporation pan 250 (i.e., the top end of the front side plate of the evaporation pan 250) and the top wall of the heat dissipation air outlet channel 2106 is not less than 5mm, preferably not less than 15mm, so as to ensure that a sufficient gap exists between the front side plate of the evaporation pan 250 and the top wall of the heat dissipation air outlet channel 2106, and reduce the wind resistance to the air flow at the gap.

As shown in fig. 14, 15, 18 and 19, in some embodiments of the present utility model, a water receiving tube 251 extending upward from the bottom plate of the evaporation pan 250 is provided in the evaporation pan 250. The lower end of the drain pipe 270 is inserted into the water receiving pipe 251 with a gap between the water receiving pipe 251 and the drain pipe 270 so that water flowing out of the drain pipe 270 can flow out of the water receiving pipe 251 from the gap and into the evaporation pan 250.

As will be appreciated by those skilled in the art, since the lower end of the drain pipe 270 is inserted into the water receiving pipe 251, a small amount of water will be stored in the water receiving pipe 251 after the defrosting of the evaporator 226 is completed to liquid-seal the bottom end of the drain pipe 270, i.e., the liquid surface in the water receiving pipe 251 is located above the bottom end of the drain pipe 270. As will be further appreciated by those skilled in the art, the bottom end of the drain pipe 270 is closed by water such that hot air within the evaporating dish 250 cannot enter the refrigerating compartment 2104 from the drain pipe 270, thereby improving the refrigerating efficiency of the refrigerating module 200.

In addition, in other embodiments of the present utility model, a sink may be provided in the evaporation pan 250 as required by those skilled in the art, and the lower end of the drain pipe 270 may be inserted into the sink. Specifically, the sink is formed on the bottom plate of the evaporation pan 250 and is recessed downward so that water can be secured in the sink even when the amount of water in the evaporation pan 250 is small, thereby ensuring that the drain pipe 270 can be water-sealed.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
