It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present utility model, but not all embodiments of the present utility model, and the some embodiments are intended to explain the technical principles of the present utility model and are not intended to limit the scope of the present utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive effort, based on the embodiments provided by the present utility model, shall still fall within the scope of protection of the present utility model.

It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Further, it should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

In addition, it should be noted that, in the description of the present utility model, the terms "cooling capacity" and "heating capacity" are two descriptions of the same physical state. That is, the higher the "cooling capacity" of a certain object (for example, evaporator, air, condenser, etc.), the lower the "heat" of the object, and the lower the "cooling capacity" of the object, the higher the "heat" of the object. Some object absorbs the cold and releases the heat, and the object releases the cold and absorbs the heat. A target maintains "cold" or "heat" to maintain the target at a current temperature. "refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, i.e., a target (e.g., an evaporator) absorbs heat while it is refrigerating.

The case module of the present utility model will be described in detail with reference to the accompanying drawings in conjunction with a refrigerator.

In the present utility model, the refrigerator may have both the freezing function and the refrigerating function, may have only the freezing function, and may have only the refrigerating function.

As shown in fig. 1 and 2, in some embodiments of the present utility model, a refrigerator includes a cabinet module 100 and a refrigeration module 200. The refrigeration module 200 serves to receive gas from the tank module 100, cool the received gas, and then supply the cooled gas to the tank module 100.

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 duct 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. 2, in some embodiments of the present utility model, a bypass hole 10111 is provided on a side wall of the first storage compartment 1011, and the bypass hole 10111 is used for installing the return air duct 140, so that air in the first storage compartment 1011 flows to the refrigeration module 200 through the return air duct 140. Air within the second storage compartment 1012 flows from the opening of the second storage compartment 1012 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 front return 21021 of the refrigeration module 200 (as shown in fig. 8). 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 front return air inlet 21021 of the refrigeration module 200, so that air in the second storage compartment 1012 flows to the refrigeration module 200 through the sink.

Furthermore, in other embodiments of the present utility model, a person skilled in the art may also provide a channel on the second door, as desired, with one end of the channel aligned with and in communication with the second storage compartment 1012, and the other end of the channel aligned with and in communication with the front return air inlet 21021 of the refrigeration module 200.

As shown in fig. 4 to 6, in some embodiments of the present utility model, a first return air passage 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 passage 1401 communicates with the escape hole 10111, so that the tank module 100 delivers air in the first storage compartment 1011 to the refrigeration module 200 through the first return air passage 1401. As can be seen from fig. 4 to 6, the cross section of the first return air channel 1401 is rectangular or bar-shaped extending back and forth, so as to reduce the size of the return air duct 140 in the left-right direction, and thus the size of the tank module 100 in the left-right direction, while ensuring that the first return air channel 1401 has corresponding ventilation performance.

As shown in fig. 5 and 6, in some embodiments of the present utility model, the return air duct 140 includes a first return air duct 141 and a second return air duct 142, the first return air duct 141 is connected to and communicates with the first liner 110 through its top end, and the second return air duct 142 is connected to and communicates with the bottom end of the first return air duct 141 through its top end.

Specifically, an end of the first bent tube section 1411 remote from the first vertical tube section 1412 is inserted into the relief hole 10111, thereby plugging the first bent tube section 1411 with the first liner 110. Preferably, the portion of the first bending section 1411 inserted into the dodging hole 10111 is parallel to the transverse direction of the first liner 110, so that the first bending section 1411 is inserted into the dodging hole 10111 along the transverse direction, and the first bending section 1411 is conveniently fixed with the first liner 110.

Furthermore, in other embodiments of the present utility model, one skilled in the art may also fluidly connect the first folded tube segment 1411 to the relief bore 10111 in any other feasible manner, such as by abutting the first folded tube segment 1411 against an outer surface of the relief bore 10111, as desired.

With continued reference to fig. 5 and 6, the first return air duct 141 further includes an optional first securing plate 1413, the first securing plate 1413 being disposed outside of the first bent pipe segment 1411. The first fixing plate 1413 is parallel to and abuts against the sidewall of the first liner 110 to ensure tightness between the first return air pipe 141 and the first liner 110. Optionally, a gasket is provided between the first fixing plate 1413 and the side wall of the first liner 110 to sealingly abut the two together through the gasket.

Further alternatively, the distance between the first fixing plate 1413 and the first vertical tube segment 1412 is smaller than the lateral dimension of the first vertical tube segment 1412 so that the lateral dimension of the first return air duct 141 is as small as possible.

With continued reference to fig. 5 and 6, the second return duct 142 extends downwardly to the bottom side of the second liner 120, the second return duct 142 including a second vertical tube section 1421 at the top thereof and a second curved tube section 1422 below the second vertical tube section 1421. Wherein the second vertical tube segment 1421 is inserted with the first vertical tube segment 1412 such that the first return air duct 141 communicates with the second return air duct 142.

As shown in fig. 6 and 7, a stopper rib 14211 is provided in the second vertical pipe section 1421, and the first vertical pipe section 1412 is inserted into the second vertical pipe section 1421 and abuts the stopper rib 14211. Optionally, a sealing member is provided between the second vertical tube section 1421 and the first vertical tube section 1412 to sealingly connect the second vertical tube section 1421 to the first vertical tube section 1412 by the sealing member. The sealing member may be any viable member, for example, a gasket located between the stop bead 14211 and the end face of the first vertical tube segment 1412.

As shown in fig. 5 and 6, a portion of the second bent pipe section 1422 remote from the second vertical pipe section 1421 is inclined downward in a lateral direction toward a direction remote from the second vertical pipe section 1421 so as to enable the second bent pipe section 1422 to be inserted into a mounting port (not shown) formed on the housing 150 side.

With continued reference to fig. 5 and 6, the second return duct 142 further includes an optional second securing plate 1423, the second securing plate 1423 being disposed outboard of the second angled duct section 1422. The second fixing plate 1423 is attached to the outer surface of the housing 150.

Wherein the first inclined portion, the first transverse portion, and the first longitudinal portion respectively abut and fit with the outer surface of the housing 150.

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 side return air port 21022 (as shown in fig. 8)) respectively, or may share one return air duct 140.

As shown in fig. 4, in some embodiments of the present utility model, the housing 150 defines a receiving cavity 102 at a bottom thereof, the receiving cavity 102 for receiving the refrigeration module 200. The receiving chamber 102 has a front opening (not shown) and a bottom opening (not shown) for moving the case module 100 from the rear side of the refrigerating module 200 to above the refrigerating module 200 so as to fix the case module 100 and the refrigerating module 200 together after the case module 100 is moved to a position matched with the refrigerating module 200.

As shown in fig. 8 and 9, in some embodiments of the present utility model, the refrigeration module 200 includes a housing 210, and the refrigeration module 200 further includes a refrigeration system 220, a heat dissipation fan 230, a blower fan 240, and an evaporation pan 250 within the housing 210.

As shown in fig. 2, in the assembled state of the refrigerator, the air supply port 2101 is abutted with the air supply pipe 130 on the box module 100, so that the refrigerating module 200 supplies air to the air supply pipe 130 through the air supply port 2101, and the air supply pipe 130 supplies cold air received by the air supply pipe to the storage compartment 101.

As shown in fig. 2 and 3, in the assembled state of the refrigerator, the front return air inlet 21021 and the second storage compartment 1012 are both positioned at the front side of the refrigerator, and both are communicated through a sink or channel formed on the second door (as described above), so that the refrigeration module 200 receives air from the second storage compartment 1012 through the front return air inlet 21021. The side return 21022 interfaces with the return air duct 140 on the cabinet module 100 such that the refrigeration module 200 receives air from the first storage compartment 1011 through the side return 21022.

Wherein the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are respectively communicated with the press bin 2103 and respectively extend from the press bin 2103 to the front end of the shell 210.

It should be noted that, for the sake of understanding by those skilled in the art, fig. 10 and 11 schematically show the relative positional relationship and distribution of four spaces of the press cabin 2103, the refrigeration compartment 2104, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106.

As can be readily seen from fig. 10 and 11, the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are all located below the refrigerating compartment 2104, and the outer contour of the projections of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane is located outside the projections of the refrigerating compartment 2104 on the horizontal plane. 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. 10 and 11, the supply-air port 2101, the front return port 21021 and the side return port 21022 are respectively communicated with the refrigerating compartment 2104. Wherein the supply-air port 2101 is located at the rear upper side of the refrigerating compartment 2104, the front return air port 21021 is located at the front upper side of the refrigerating compartment 2104, and the side return air port 21022 is located at the side upper side of the refrigerating compartment 2104.

As shown in fig. 9, 12 to 14, the compressor 221, the condenser 223 and the dry filter 224 are all disposed in the press housing 2103, the high-temperature pipeline 222 is distributed in the press housing 2103 and the heat radiation air outlet passage 2106, and the evaporator 226 is disposed in 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.

As shown in fig. 9 and 16 to 19, the heat radiation fan 230 is disposed in the press housing 2103, the air supply fan 240 is disposed in the cooling compartment 2104, and the evaporation pan 250 is disposed in the heat radiation air outlet passage 2106. At least a portion of the high temperature conduit 222 located within the heat dissipation air outlet channel 2106 is located within the evaporation pan 250 such that the high temperature conduit 222 is capable of heating water within the evaporation pan 250 to facilitate evaporation of the water.

As shown in fig. 16 to 19, in some embodiments of the present utility model, a lateral gap 21071 is formed between the top plate of each of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 and the bottom plate of the refrigeration compartment 2104, and the lateral gap 21071 is filled with a thermal insulation material (such as a foaming agent or thermal insulation cotton). 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.

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.

The side return air inlet 21022 is formed on the right side slope of the housing 210 and is located at the front of the housing 210.

Correspondingly, the outlet end of the return air duct 140 of the cabinet module 100 is also inclined such that the outlet end of the return air duct 140 is parallel to the right side inclined surface of the housing 210.

Furthermore, in other embodiments of the present utility model, the side return 21022 may be disposed in the middle or rear of the housing 210 as desired by one skilled in the art; and the side return air inlet 21022 is formed on the left inclined surface of the casing 210 as required, and the avoiding hole 10111 and the return air pipe 140 on the case module 100 are disposed on the left side of the case module 100.

In still other embodiments of the present utility model, it is also possible for those skilled in the art to provide side return air inlets 21022 on the left and right inclined surfaces of the housing 210, respectively, and to provide the bypass holes 10111 and the return air duct 140 on the left and right sides of the cabinet module 100, respectively, as desired. Optionally, the two avoiding holes 10111 and the two return air pipes 140 correspond to the same storage compartment, or each avoiding hole 10111 and each return air pipe 140 respectively correspond to one storage compartment.

As shown in fig. 19-21, in some embodiments of the utility model, the housing 210 further includes a wind-guiding member 280, the wind-guiding member 280 for communicating the side return 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 side 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. 20 and 21, 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. 13 and 14, 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. 13 and 15, 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. 13 to 16, 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. 13 to 16, 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. 15, 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. 13-15, 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. 13-15, in some embodiments of the present 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. 13 to 15, 17 and 18, 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. 17 and 18). 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. 13 and 14, 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. 15 to 17, 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. 13, 14, 17 and 18, 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 case module 100 and the refrigeration module 200 of the present utility model have been described in detail with reference to the accompanying drawings. Based on the foregoing, it can be understood by those skilled in the art that in the present utility model, by arranging the evaporator 226 to be inclined upward in the front-to-rear direction, the value of the included angle between the evaporator 226 and the horizontal plane is set to be 8 ° to 45 °, so that the evaporator 226 occupies a smaller space in the vertical direction and occupies a smaller space in the front-to-rear direction, so that the refrigerating room 2104 can reserve more space to arrange the air blower 240, and a sufficient gap is provided between the air blower 240 and the evaporator 226, thereby avoiding the excessive wind resistance and affecting the energy consumption of the refrigerator.

Further, by arranging the outer contours of the projections of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane outside the projection of the refrigerating compartment 2104 on the horizontal plane and filling the heat insulation materials in the transverse gap 21071, the front gap 21072 and the longitudinal gap 21073 outside the refrigerating compartment 2104, 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 refrigerating compartment 2104, and the refrigerating compartment 2104 is ensured not to leak cold and the structure of the refrigerating module 200 is more compact.

Further, by disposing the evaporation pan 250 in the heat dissipation air outlet channel 2106, the evaporation pan 250 can heat the water in the evaporation pan 250 by utilizing the heat of the whole press bin 2103, thereby improving the evaporation rate of the water in the evaporation pan 250.

Further, by extending the drain pipe 270 from the top down into the evaporation pan 250, the defrost water in the refrigeration compartment 2104 can be quickly drained into the evaporation pan 250. By inserting the lower end of the drain pipe 270 into the water receiving pipe 251, a small amount of water is 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. As will be appreciated by those skilled in the art, the bottom end of the drain pipe 270 is closed by water, so that hot air in 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.

Meanwhile, the above-described structure of the refrigerating module 200 also makes the entire refrigerating module 200 flatter, leaving more space for the case module 100 thereon.

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.
