In other words, the first storage chamber 1011 is defined by the first inner container 110, and the second storage chamber 1012 is defined by the second inner container 120. An air supply channel 1301 is defined in the air supply pipeline 130, and the air supply channel 1301 is communicated with the first storage chamber 1011 and the second storage chamber 1012 respectively, so that the box body module 100 receives cold air from the refrigeration module 200 through the air supply channel 1301 and conveys the cold air to the first storage chamber 1011 and the second storage chamber 1012.

As shown in fig. 3, a first air return channel 1401 (shown by a dotted line in fig. 3) is formed in the air return pipeline 140, and a top end of the first air return channel 1401 is communicated with the first air outlet 10111, or the first air outlet 10111 forms an inlet of the first air return channel 1401; so that the box module 100 delivers the air in the first storage compartment 1011 to the refrigeration module 200 through the first return air duct 1401.

Furthermore, in some embodiments of the present invention, the storage compartment 101 may be set to any other feasible number, such as one, three, five, six, etc., as required by those skilled in the art. Those skilled in the art will also appreciate that the tank module 100 can include other numbers of bladders, such as one, three, four, etc., as desired. For example, the case module 100 may include only one inner container, and the inner container may define one or more storage compartments. When the inner container defines only one storage compartment, the storage compartment may 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 inner container defines a plurality of storage compartments, the storage compartment at the bottom delivers the air therein to the refrigeration module 200 in the manner of the second storage compartment 1012 as described above; the other storage compartments deliver the air therein to the refrigeration module 200 by using the first storage compartment 1011 as described above, and each storage compartment may correspond to one return air duct 140 (each return air duct 140 corresponds to one side return air inlet 21022 (as shown in fig. 5)), or share one return air duct 140.

As shown in fig. 3 and 4, in some embodiments of the present invention, the cabinet module 100 further defines a receiving cavity 102 at the bottom thereof, and the receiving cavity 102 is used for receiving the refrigeration module 200.

As shown in fig. 4, a rear portion of the top wall of the receiving chamber 102 is provided with a case module inlet 1021. The box module air inlet 1021 is communicated with the air supply pipeline 130, or is formed at the bottom end of the air supply pipeline 130 (i.e. the bottom end of the air supply pipeline 130 extends to the top wall of the accommodating cavity 102). In the assembled state of the cabinet module 100 and the refrigeration module 200, the cabinet module air intake 1021 is butted together with the refrigeration module air supply outlet 2101 on the refrigeration module 200.

As shown in fig. 5 to 11, in some embodiments of the present invention, 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 blowing fan 240 and an evaporation pan 250 in the housing 210.

As shown in fig. 2 and 12 to 14, in a state where the refrigerator is assembled, the cooling module air inlet 2101 and the cabinet module air inlet 1021 of the cabinet module 100 are butted together, so that the cooling module 200 supplies air to the air supply duct 130 through the cooling module air inlet 2101, and the air supply duct 130 supplies the received cool air to the storage compartment 101.

As shown in fig. 1 and 2, in the assembled state of the refrigerator, the front air return port 21021 and the second storage compartment 1012 are both located at the front side of the refrigerator and are communicated with each other through a sink or channel formed on the second door body (as described above), so that the refrigeration module 200 receives air from the second storage compartment 1012 through the front air return port 21021. The side air return port 21022 interfaces with the return air duct 140 on the cabinet module 100 so that the refrigeration module 200 receives air from the first storage compartment 1011 through the side air return port 21022.

Wherein, heat dissipation inlet duct 2105 and heat dissipation air-out passageway 2106 communicate with press storehouse 2103 respectively to extend to the front end of casing 210 from press storehouse 2103 respectively.

It should be noted that, in order to facilitate understanding of those skilled in the art, fig. 8 schematically shows relative position relationships and distribution of four spaces of the press cabin 2103, the refrigerating compartment 2104, the heat dissipation air inlet duct 2105 and the heat dissipation air outlet duct 2106.

Most of the tube sections of the capillary tube 225 and the return tube 227 are located outside of the press chamber 2103 and the refrigeration compartment 2104. Alternatively, one skilled in the art may position all of the capillary tube 225 and/or the return tube 227 outside of the press chamber 2103 and the refrigeration compartment 2104, as desired.

As shown in fig. 9 and 10, the heat dissipation fan 230 is disposed in the press bin 2103, the air supply fan 240 is disposed in the cooling compartment 2104, and the evaporation pan 250 is disposed in the heat dissipation air outlet passage 2106. At least a part of the portion of the high temperature pipeline 222 located in the heat dissipation air outlet channel 2106 is located in the evaporation pan 250, so that the high temperature pipeline 222 can heat the water in the evaporation pan 250 to promote evaporation of the water.

As shown in fig. 11, in some embodiments of the present invention, a lateral gap (not labeled in the figure) is formed between the top plate of each of the press chamber 2103, the heat dissipation air inlet passage 2105 and the heat dissipation air outlet passage 2106 and the bottom plate of the refrigeration chamber 2104, and the lateral gap is filled with a thermal insulation material (e.g., a foaming agent or thermal insulation cotton). A front gap (not shown) is formed between the bottom of the front plate of the cooling compartment 2104 and the adjacent outer plate of the housing 210, and the front gap is filled with an insulating material (such as a foaming agent or insulating cotton). A longitudinal gap (not shown) is formed between the left and right side plates of the cooling compartment 2104 and the outer side plate of the respective adjacent housing 210, and the longitudinal gap is filled with an insulating material (e.g., a foaming agent or insulating cotton). It will be appreciated by those skilled in the art that the insulation material outside the refrigeration compartment 2104 can effectively insulate the refrigeration compartment 2104 from cold leakage.

Further, the respective top plates of the press cabin 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 chamber 2104, so that the heat insulation materials in the transverse gap, the front gap and the longitudinal gap are filled uniformly and uniformly in thickness, and the refrigeration chamber 2104 is uniformly insulated.

As shown in fig. 11, the refrigeration module 200 further comprises a pressure plate 260 disposed between the evaporator 226 and the ceiling of the refrigeration compartment 2104, the pressure plate 260 serving to press the evaporator 226 against the floor of the refrigeration compartment 2104, thereby securing the evaporator 226 obliquely within the refrigeration compartment 2104.

Preferably, the supply 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 a direction in which an axis of the impeller extends.

In addition, the skilled person can set the air supply fan 240 as any other feasible fan, such as a cross-flow fan, an axial flow fan, etc., as required.

As shown in fig. 5, 6 and 11, the rear of the ceiling of the refrigeration compartment 2104 (i.e., the rear of the ceiling of the housing 210) is sloped downward from front to back such that the rear of the ceiling of the housing 210 forms a sloped outer ramp (not labeled) on which the refrigeration module air supply outlet 2101 is formed. As can be readily seen, the refrigeration module supply opening 2101 is centered on this outer slope and thus the refrigeration module supply opening 2101 is disposed laterally in the middle of the top panel of the housing 210. Further, the cooling module air supply outlet 2101 is a rectangular opening extending in the lateral direction.

Correspondingly, the rear portion of the top wall of the accommodating cavity 102 is also inclined downward from front to rear to form an inclined inner slope (not labeled in the figure).

Further, the case module air inlet 1021 is also a rectangular opening extending laterally.

Preferably, the inner slope on the top wall of the receiving cavity 102 is parallel to the outer slope on the refrigeration module 200.

Preferably, the front air return port 21021 is a laterally extending strip-shaped opening.

As shown in fig. 5 to 7, the junction between the top side plate and the left side plate of the housing 210 is set as an inclined surface, and the junction between the top side plate and the right side plate of the housing 210 is also set as an inclined surface. The side air return port 21022 is formed on the right side inclined surface of the housing 210 and is located at the front of the housing 210.

Correspondingly, the outlet end of the return air duct 140 on the tank module 100 is also inclined, so that the outlet end of the return air duct 140 is parallel to the right inclined surface of the casing 210.

In addition, in other embodiments of the present invention, a person skilled in the art may also dispose the side air return port 21022 in the middle or rear portion of the housing 210 as required; and a side air return port 21022 is formed on the left side inclined surface of the case 210 as needed, and the first air outlet 10111 and the air return duct 140 on the tank module 100 are provided on the left side of the tank module 100.

In still other embodiments of the present invention, a person skilled in the art can set the side air return port 21022 on the left side inclined plane and the right side inclined plane of the housing 210, and set the first air outlet 10111 and the air return pipeline 140 on the left side and the right side of the box module 100, respectively, as required. Optionally, the two first air outlets 10111 and the two air return pipelines 140 correspond to the same storage chamber, or each first air outlet 10111 and each air return pipeline 140 correspond to one storage chamber respectively.

In still other embodiments of the present invention, one skilled in the art can set only one of the junction between the top side plate and the left side plate of the casing 210 and the junction between the top side plate and the right side plate of the casing 210 to be an inclined surface, and set the side air return port 21022 on the inclined surface, as needed.

As shown in fig. 10, in the left-right direction of the refrigeration module 200, the compressor 221, the heat dissipation fan 230, and the condenser 223 are sequentially arranged between the heat dissipation air outlet duct 2106 and the heat dissipation air inlet duct 2105, and the heat dissipation fan 230 and the condenser 223 are disposed in close proximity to reduce the size of the refrigeration module 200 in the lateral direction.

As can be seen from fig. 5 to 7 and 11, a gap is formed between the bottom plate of each of the heat dissipation air inlet duct 2105 and the heat dissipation air outlet duct 2106 and a bearing surface (e.g., a floor or a floor).

As shown in fig. 7 and 10, the heat dissipation air intake duct 2105 includes a plurality of front air openings 21051 formed on a front side plate of the case 210 so that external air can enter the heat dissipation air intake duct 2105 from the plurality of front air openings 21051. Further, the heat dissipation air intake duct 2105 further includes a plurality of bottom side air inlets 21052 formed on the bottom plate of the heat dissipation air intake duct 2105, so that the external air can enter the heat dissipation air intake duct 2105 through the gap below the heat dissipation air intake duct 2105 and the plurality of bottom side air inlets 21052.

As can be understood by those skilled in the art, since the heat dissipation air intake duct 2105 has a plurality of front air inlets 21051 at the front side thereof and a plurality of bottom air inlets 21052 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. The problem that the air inlet is not smooth due to the limitation of the area of the front side plate of the heat dissipation air inlet channel 2105 when the heat dissipation air inlet channel 2105 is only provided with a plurality of front air inlets 21051 is avoided; and the situation that the heat dissipation air inlet passage 2105 cannot obtain enough air due to blockage of the bottom air inlet 21052 caused by accumulation of impurities such as dust and lint at the bottom air inlet 21052 when the heat dissipation air inlet passage 2105 only has a plurality of bottom air inlets 21052 is also avoided.

With continued reference to fig. 7 and 10, the heat dissipating air outlet duct 2106 includes a plurality of front air outlets 21061 formed on the front side plate of the casing 210, so that the hot air in the heat dissipating air inlet duct 2105 can flow out from the plurality of front air outlets 21061 to the outside. Optionally, the heat dissipation air outlet duct 2106 includes a plurality of bottom side air outlets (not shown) formed on a bottom plate thereof.

As shown in fig. 7, the housing 210 further includes a wind deflector 215 disposed on the bottom side of the bottom plate of the press chamber 2103, and the wind deflector 215 is used to prevent the bottom side wind inlet 21052 from sucking the hot wind blown out from the front wind outlet 21061.

With continued reference to fig. 7 and 10, the bottom plate of the pressing chamber 2103 is provided with a plurality of chamber bottom air inlets 21031 at the windward side of the condenser 223, and the bottom plate of the pressing chamber 2103 is provided with a plurality of chamber bottom air outlets 21032 at the side of the heat dissipation fan 230 away from the condenser 223. And the plurality of bottom side air intakes 21052 and the plurality of bottom bin air intakes 21031 are located on one side of the air deflector 215, and the plurality of bottom bin air outlets 21032 are located on the other side of the air deflector 215. Based on this, it can be understood by those skilled in the art that the outside air can also enter the pressing chamber 2103 through the chamber bottom air inlet 21031, and a part of the hot air in the pressing chamber 2103 flows to the outside from the chamber bottom air outlet 21032.

As can be seen from fig. 7 and 10, in some embodiments of the present invention, a portion of the plurality of bottom outlet ports 21032 is located below the compressor 221, and another portion of the plurality of bottom outlet ports 21032 is located at the front side of the compressor 221.

As shown in fig. 10 and 11, a plurality of bin bottom air outlets 21032 located at the front side of the compressor 221 are adjacent to the evaporation pan 250.

As will be understood by those skilled in the art, the airflow blocked by the rear plate of the evaporation pan 250 can be reflected to the plurality of bottom outlets 21032 on the front side of the compressor 221, and then flows to the outside through the plurality of bottom outlets 21032 (as shown in fig. 11). For the structure without the bin bottom air outlet 21032 at the rear side of the evaporation dish 250, the structure can effectively avoid the shielding effect of the rear side plate of the evaporation dish 250 on the air flow, and further effectively avoid the air flow from generating a cyclone at the rear side plate of the evaporation dish 250. Therefore, in some embodiments of the present invention, the blocking effect of the rear side plate of the evaporating dish 250 on the air flow can be effectively eliminated, and the corresponding noise can be eliminated.

In other embodiments of the present invention, the plurality of bottom outlet 21032 may be arranged in any other feasible form, for example, the plurality of bottom outlet 21032 may be arranged on the front side, the right side and the bottom side of the compressor 221, or arranged on the front side and/or the right side of the compressor 221, as required by those skilled in the art.

As shown in fig. 10, in some embodiments of the present invention, the structure of the evaporation pan 250 in the horizontal direction is adapted to the structure of the heat dissipation air-out channel 2106 in the horizontal direction, that is, the evaporation pan 250 is parallel to the opposite side of the heat dissipation air-out channel 2106, so that the evaporation pan 250 can be spread over the whole heat dissipation air-out 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-back 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 on the path of the air flowing in the heat dissipation air outlet channel 2106, thereby increasing the contact time between the water in the evaporation pan 250 and 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 evaporation pan 250 is gradually reduced from back to front, and the width of the front portion of the heat dissipation air-out channel 2106 is also gradually reduced from back to front, so that the flow area of the front portion of the heat dissipation air-out channel 2106 is gradually reduced, and the flow speed of the air flow at the front portion of the evaporation pan 250 is gradually increased, so as to ensure the evaporation rate of the water in the front portion of the evaporation pan 250.

As can be understood by those skilled in the art, in the heat dissipation air outlet passage 2106, since the temperature of the air flow is higher immediately after entering the evaporation pan 250, the air flow has a good heating effect on the water in the evaporation pan 250; however, as the airflow approaches the front air outlet 21061, the airflow absorbs more heat and has lower temperature, so that the heating effect of the airflow on the water is poor. And the width of the evaporating dish 250 and the front part of the heat dissipation air-out channel 2106 is gradually reduced from back to front, so that the flow area of the front part of the heat dissipation air-out channel 2106 is gradually reduced, and the flow speed of the air flow at the position is gradually increased, and the air flow can overcome the influence of low temperature on the water evaporation efficiency at high flow speed. Therefore, in some embodiments of the present invention, the width of the front portion of the evaporation dish 250 and the heat dissipation air-out channel 2106 is gradually reduced from back to front, so as to improve the evaporation efficiency of the air flow in the heat dissipation air-out channel 2106 to the water in the evaporation dish 250.

Further, the distance between the front surface of the evaporation pan 250 and the front side plate of the housing 210 in the front-rear direction of the refrigeration module 200 is not less than 5mm, preferably not less than 15mm, to ensure that there is a sufficient gap between the front surface of the evaporation pan 250 and the front side plate of the housing 210, and to reduce the wind resistance thereto.

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-out channel 2106 is not less than 5mm, and preferably not less than 15mm, so as to ensure that there is enough gap between the front side plate of the evaporation pan 250 and the top wall of the heat dissipation air-out channel 2106, and reduce the wind resistance to the air flow there.

As shown in fig. 11, in some embodiments of the present invention, a water receiving pipe 251 is disposed in the evaporation pan 250 and extends upward from the bottom plate of the evaporation pan 250. The lower end of drain pipe 270 is inserted into water receiving pipe 251, and a gap is provided between water receiving pipe 251 and drain pipe 270, so that water flowing out of drain pipe 270 can flow out of water receiving pipe 251 through the gap and into evaporation pan 250.

As will be understood 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 finished to seal the bottom end of the drain pipe 270, i.e., the liquid level in the water receiving pipe 251 is above the bottom end of the drain pipe 270. It will be further appreciated by those skilled in the art that the bottom end of the drain pipe 270 is sealed by water, so that the hot air in the evaporating dish 250 cannot enter the cooling compartment 2104 from the drain pipe 270, thereby improving the cooling efficiency of the cooling module 200.

In addition, in other embodiments of the present invention, a person skilled in the art may also set a sink in the evaporation pan 250 and insert the lower end of the drain pipe 270 into the sink, as needed. Specifically, the sink is formed on the bottom plate of the evaporation pan 250 and is recessed downward so as to ensure that water is contained therein even when the amount of water in the evaporation pan 250 is small, thereby ensuring that the drain pipe 270 can be water-sealed.

Up to this point, the respective main structures of the case module 100 and the refrigeration module 200 of the present invention have been described in detail with reference to the accompanying drawings. The connection between the cooling module air inlet 2101 and the housing module air inlet 1021 is described in detail with reference to fig. 12-14.

As shown in fig. 12 and 13, in some embodiments of the present invention, the refrigerator further includes a thermal insulation structure 300 disposed between the case module 100 and the refrigeration module 200, and the thermal insulation structure 300 is used for insulating the structures at the air inlet 2101 and the air inlet 1021 of the case module to reduce the exposure of the structures.

Preferably, the insulation structure 300 is a sheet structure or a plate structure made of foam. Alternatively, the thermal insulation structure 300 may be any other feasible structure, such as a foam board, a rubber pad, a silicone pad, etc., as required by those skilled in the art.

Further, the insulation structure 300 may be bonded to one of the tank module 100 and the refrigeration module 200; and to engage the other of the tank module 100 and the refrigeration module 200 after the tank module 100 and the refrigeration module 200 are assembled. Alternatively, the skilled person may also attach the insulation structure 300 to the cabinet module 100 and the refrigeration module 200, respectively, after the cabinet module 100 and the refrigeration module 200 are assembled.

It is further preferable that the insulation structure 300 is pressed by the tank module 100 in a vertical direction to be compressed, thereby making the tank module 100 and the refrigeration module 200 be more closely attached.

As shown in fig. 12 and 13, in some embodiments of the invention, the rear side plate of the cabinet module 100 and the rear side plate of the refrigeration module 200 are also fastened together by bolts 400. Specifically, the rear wall of the receiving cavity 102 and the rear plate of the housing 210 are fastened together by bolts 400. The bolt 400, in addition to serving to fix the tank module 100 and the refrigeration module 200 together, can provide a force to the rear wall of the receiving chamber 102 and the rear plate of the housing 210 to approach each other, so that the rear wall of the receiving chamber 102 and the rear plate of the housing 210 clamp a portion of the insulation structure 300 therebetween, to prevent a gap from being formed between each of the rear wall of the receiving chamber 102 and the rear plate of the housing 210 and the insulation structure 300.

Further, the screw 400 may be replaced with a screw as needed by those skilled in the art.

As shown in fig. 12 to 14, in some embodiments of the present invention, a gap 500 for placing or filling the insulation structure 300 is formed between the case module 100 and the refrigeration module 200. This gap 500 surrounds the refrigeration module supply air outlet 2101 and the case module air inlet 1021, in other words, the refrigeration module supply air outlet 2101 and the case module air inlet 1021 are located within the gap 500.

As shown in fig. 14, in some embodiments of the present invention, the gap 500 is defined as a bent shape, so that the insulation structure 300 in the gap 500 is also arranged in a bent shape, thereby the insulation structure 300 has better insulation effect.

With continued reference to fig. 14, the gaps 500 include, in particular, vertical gaps 510, slanted gaps 520, lateral gaps 530, and arcuate gaps 540. Wherein, vertical clearance 510 is formed between the back wall of holding chamber 102 and the back plate of casing 210 to vertical clearance 510 downwardly extending to press storehouse 2103 to the bottom of insulation structure 300 can be heated to the hot-air in press storehouse 2103, has prevented that the refrigerator from appearing the condensation here. Preferably, the bottom end of the vertical gap 510 is flush with the top wall of the press silo 2103. In other words, the vertical gap 510 extends down to the top wall of the press bin 2103. Further, one skilled in the art may also extend the vertical gap 510 down to the rear sidewall of the press silo 2103 as desired.

With continued reference to fig. 14, an angled gap 520 is formed between the rear of the top wall of the receiving cavity 102 and the rear of the top plate of the housing 210. That is, the inclined gap 520 is formed between the inner slope on the tank module 100 and the outer slope of the refrigeration module 200. A lateral gap 530 is formed in the front of the case module air intake 1021 and the refrigeration module air supply outlet 2101.

With continued reference to fig. 14, the junction between the top wall and the rear wall of the receiving cavity 102 is provided with an arc-shaped chamfer (not labeled), the junction between the top plate and the rear plate of the housing 210 is provided with an arc-shaped chamfer (not labeled), and an arc-shaped gap 540 is formed between the two arc-shaped chamfers. Those skilled in the art will appreciate that the two curved chamfers enable the tank module 100 and the refrigeration module 200 to engage with the insulation structure 300 at the junction of the vertical gap 510 and the inclined gap 520 through the respective curved chamfers and compress the insulation structure 300. Meanwhile, the arc-shaped chamfer angle does not excessively extrude or even break the heat insulation structure 300 relative to the edge structure without the arc-shaped chamfer angle, so that the heat insulation effect of the heat insulation structure 300 on the refrigerator is ensured.

It can be seen that the lateral gap 530, the oblique gap 520, the arc gap 540, and the vertical gap 510 are sequentially distributed from front to back. As will be appreciated by those skilled in the art, since the case module air inlet 1021 and the refrigeration module air outlet 2101 are formed at the inclined gap 520, the design of the inclined gap 520 prolongs the path of the case module air inlet 1021 and the refrigeration module air outlet 2101 to the outside.

As shown in fig. 12 and 13, the vertical gap 510, the inclined gap 520, the lateral gap 530, and the arc gap 540 are filled with the insulation structure 300. Preferably, the insulation structure 300 filled in the vertical gap 510, the inclined gap 520, the transverse gap 530 and the arc-shaped gap 540 is integrated, so that the size of the insulation structure 300 is sufficiently large in the extending direction of the gap 500.

Based on the foregoing description, it can be understood by those skilled in the art that in the present invention, by forming the gap 500 between the box module 100 and the refrigeration module 200 around the box module air inlet 1021 and the refrigeration module air supply opening 2101, and filling the thermal insulation structure 300 in the gap 500, the thermal insulation structure 300 can perform the thermal insulation function on the structures at the box module air inlet 1021 and the refrigeration module air supply opening 2101, so as to reduce the exposure of the refrigerator at this position, and further improve the refrigeration efficiency of the refrigerator.

Further, by providing the gap 500 with the vertical gap 510 formed between the rear wall of the accommodating cavity 102 and the rear plate of the housing 210 and extending the vertical gap 510 downward to the press bin 2103, not only is the area of the insulation structure 300 on the rear side of the box module air inlet 1021 and the refrigeration module air outlet 2101 increased, but also the insulation performance of the insulation structure 300 is improved; but also enables the hot air in the press chamber 2103 to heat the bottom end of the heat preservation structure 300, thereby preventing the refrigerator from generating condensation at the position.

Still further, since the box module air inlet 1021 and the cooling module air supply outlet 2101 are aligned with the inclined gap 520, and the box module air inlet 1021 and the cooling module air supply outlet 2101 are both rectangular openings extending in the transverse direction, by positioning the inclined gap 520 in the middle of the gap 500 in the front-rear direction, the distance between the box module air inlet 1021 and the cooling module air supply outlet 2101 (especially the long sides of the two) and the outside in the extending direction of the gap 500 is large enough, so that the amount of exposed cold of the refrigerator at the box module air inlet 1021 and the cooling module air supply outlet 2101 is small.

Further, since the insulation structure 300 (especially, the portion in the inclined gap 520) is compressed by being pressed by the case module 100 in the vertical direction, the gap 500 is made smaller, or the insulation structure 300 is made to sufficiently fill the gap 500, which avoids the flow of air and the transfer of heat, and further makes the insulation effect of the insulation structure 300 better. The bolt 400 also enables the part of the heat preservation structure 300 in the inclined gap 520 to be extruded in the horizontal direction, so that the part of the heat preservation structure 300 in the inclined gap 520 is fully extruded in the vertical direction and the horizontal direction, and the sealing effect of the heat preservation structure on the air inlet 1021 of the box module and the air outlet 2101 of the refrigeration module is ensured.

In other embodiments of the present invention, the gap 500 may optionally further include a side gap (not shown) formed between the side wall of the accommodating cavity 102 and the side plate of the housing 210, and the side gap is also filled with the thermal insulation structure 300.

So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without deviating from the technical principle of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and also can make equivalent changes or substitutions for related technical features, and any changes, equivalent substitutions, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
