Background technique

The overall shape, number of internal compartments and volume of internal compartments of the same series of refrigerators are the same. Refrigerators of different models often differ only in color and shell material. Due to the different layouts and decoration styles of different families and the different preferences of different users, the existing refrigerators cannot meet the needs of the majority of users. And manufacturers cannot provide users with customized refrigerators according to their needs. The reason is that the existing refrigerators generally integrate the refrigeration system into the refrigerator body, so manufacturers need to redesign the structure and layout of the refrigerator according to the needs of users. For this purpose, more new molds need to be opened, resulting in high production costs and long production cycles for refrigerators.

In order to overcome the above problems, the prior art proposes a modular refrigerator solution. Specifically, the refrigerator is designed into two independent modules: a cabinet module and a refrigeration module. The refrigeration module can adapt to a variety of different cabinet modules, so that the refrigeration module and the corresponding cabinet module can be assembled together according to the user's customized needs.

However, the volume of the refrigeration module in the existing refrigerator is relatively large, which affects the size of the cabinet module and further affects the volume of the refrigerator, resulting in a smaller effective volume of the refrigerator.

In a second aspect, the present invention provides a freezing and refrigerating device, comprising a cabinet module and a refrigeration module described in any one of the first aspects, wherein the cabinet module defines a storage compartment, an air supply channel connected to the storage compartment, and a return air channel connected to the storage compartment, wherein the air supply channel is fluidly connected to the air supply port of the refrigeration module through an end thereof away from the storage compartment, and the return air channel is fluidly connected to the return air port of the refrigeration module through an end thereof away from the storage compartment.

Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the present invention, the projection area of the evaporator on the horizontal plane is larger than the projection area on the vertical plane, so that the evaporator in the refrigeration room has a smaller size in the vertical direction, thereby making the refrigeration module have a smaller size in the vertical direction, and further making the cabinet module able to occupy more space in the vertical direction to increase the volume of the cabinet module.

Furthermore, by arranging the evaporator to be tilted upward from the front to the back, the angle between the evaporator and the horizontal plane is in the range of 8° to 45°, so that the evaporator occupies a smaller space in the vertical direction and a smaller space in the front-to-back direction, so that more space can be reserved in the refrigeration compartment for arranging the air supply fan, and there is a sufficient gap between the air supply fan and the evaporator, so as to avoid excessive wind resistance and affect the energy consumption of the refrigeration equipment.

Furthermore, by setting the air supply fan as a centrifugal fan and ensuring that the position on the top surface of the centrifugal fan where the rotating shaft of its impeller is aligned is not less than 30 mm from the top plate of the refrigeration compartment, the air suction capacity of the centrifugal fan is ensured and excessive wind resistance at the inlet of the centrifugal fan is avoided.

Furthermore, by extending the heat dissipation air inlet channel and the heat dissipation air outlet channel from the compressor compartment to the front end of the shell, the refrigeration module can introduce cold air from the front side to cool the compressor compartment, and Expel the hot air in the press chamber from the front.

Furthermore, by making the outer contours of the projections of the press chamber, the heat dissipation air inlet channel and the heat dissipation air outlet channel on the horizontal plane be located outside the projection of the refrigeration compartment on the horizontal plane, and filling the transverse gap, the longitudinal gap and the front gap outside the refrigeration compartment with insulation material, the top plates of the press chamber, the heat dissipation air inlet channel and the heat dissipation air outlet channel are respectively parallel to the bottom plate of the refrigeration compartment, which ensures that the refrigeration compartment does not leak cold and makes the structure of the refrigeration module more compact.

Furthermore, by arranging the evaporating dish in the heat dissipation air outlet channel, the evaporating dish can utilize the heat of the entire compressor chamber to heat the water therein, thereby improving the evaporation rate of the water in the evaporating dish.

Furthermore, by providing a drainage hole at the bottom of the refrigeration compartment below the front of the evaporator, and by providing the bottom of the refrigeration compartment with an evaporator support section extending obliquely backward and upward at the rear side of the drainage hole, the defrost water of the evaporator can flow quickly to the drainage hole along the inclined structure of the evaporator itself and along the evaporator support section, thereby increasing the drainage effect of the evaporator. By making the inclination angle of the air supply fan support section greater than the inclination angle of the evaporator support section, while ensuring that the defrost water of the air supply fan flows quickly to the drainage hole, the angle between the opening direction of the air inlet of the air supply fan and the flow direction of the air flow out of the evaporator is made as small as possible, thereby reducing the air suction resistance of the air supply fan.

Furthermore, by extending the drain pipe from top to bottom into the evaporating dish, the defrosted water in the refrigerating room can be quickly discharged into the evaporating dish. By inserting the lower end of the drain pipe into the water receiving pipe and providing a gap between the water receiving pipe and the drain pipe, the water flowing out of the drain pipe can flow out from the gap to the external space of the water receiving pipe in the evaporating dish, and then a small amount of water will be stored in the water receiving pipe after the evaporator defrosts, and the bottom end of the drain pipe will be liquid-sealed. It can be understood by those skilled in the art that since the bottom end of the drain pipe is sealed by water, the hot air in the evaporating dish cannot enter the refrigerating room from the drain pipe, thereby improving the refrigeration efficiency of the refrigeration module.

Furthermore, by making the rear section of the top plate of the refrigerating compartment tilt downward from front to back and forming the air outlet on the rear section, when the cabinet module is installed on the refrigerating module from back to front, the cabinet module can be abutted against the rear section in the horizontal direction, so that The box module is sealed and connected to the air outlet. When the box module abuts against the top plate of the refrigeration compartment, the characteristics of the rear section also avoid or reduce the weight of the box module it bears, making it less likely to deform, thereby ensuring the reliability of the fluid connection between the box module and the refrigeration module at the air outlet.

Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

2 , a first air outlet 10111 is provided on the side wall of the first storage compartment 1011 so that the air in the first storage compartment 1011 flows to the refrigeration module 200 through the first air outlet 10111. The air in the second storage compartment 1012 flows to the refrigeration module 200 from the opening of the second storage compartment 1012.

Furthermore, although not shown in the figure, in some embodiments of the present invention, the cabinet module 100 further includes a first door body corresponding to the first storage compartment 1011 and a second door body corresponding to the second storage compartment 1012. The first door body is used to shield the first storage compartment 1011 to prevent the outside air from entering the first storage compartment 1011. The second door body is used to shield the second storage compartment 1012 to prevent the outside air from entering the second storage compartment 1012; the second door body is also used to shield the top of the refrigeration module 200, specifically, to shield the front return air outlet of the refrigeration module 200. Further, a sink groove is provided on the inner side of the second door body, and the sink groove has a portion aligned with and connected to the second storage compartment 1012 and a portion aligned with and connected to the front return air outlet 21021 of the refrigeration module 200, so that the air in the second storage compartment 1012 flows to the refrigeration module 200 through the sink groove.

In addition, in some other embodiments of the present invention, those skilled in the art may also, as needed, set a channel on the second door body, and align and connect one end of the channel with the second storage compartment 1012, and align and connect the other end of the channel with the front return air outlet 21021 of the refrigeration module 200.

As shown in FIGS. 2 to 4 , in some embodiments of the present invention, the cabinet module 100 includes a first inner liner 110, a second inner liner 120, an air supply duct 130, and an air return duct 140 disposed in its housing (not marked in the figures). A first storage compartment 1011 is formed in the first inner liner 110, and a second storage compartment 1012 is formed in the second inner liner 120. In other words, the first storage compartment 1011 is defined by the first inner liner 110, and the second storage compartment 1012 is defined by the second inner liner 120. An air supply channel 1301 is defined in the air supply duct 130, and the air supply channel 1301 is communicated with the first storage compartment 1011 and the second storage compartment 1012, respectively, so that the cabinet 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.

And they extend from the press chamber 2103 to the front end of the shell 210 respectively.

It should be noted here that, in order to facilitate the understanding of those skilled in the art, Figures 7 and 8 both schematically show the relative position relationship and distribution of the four spaces of the compressor chamber 2103, the refrigeration chamber 2104, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106.

It is not difficult to see from FIG. 7 and FIG. 8 that the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are all located below the refrigeration chamber 2104, and the outer contours of the projections of the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane are located outside the projection of the refrigeration chamber 2104 on the horizontal plane. In other words, if the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are regarded as a whole, the projection of the refrigeration chamber 2104 on the horizontal plane is located inside the projection of the whole on the horizontal plane.

As shown in Figures 7 and 8, the air supply port 2101, the front air return port 21021 and the side air return port 21022 are respectively connected to the refrigeration compartment 2104. The air supply port 2101 is located at the upper rear of the refrigeration compartment 2104, the front air return port 21021 is located at the upper front of the refrigeration compartment 2104, and the side air return port 21022 is located at the upper side of the refrigeration compartment 2104.

As shown in FIG. 6 , in some embodiments of the present invention, the refrigeration system 220 includes a compressor 221, a high-temperature pipeline 222, a condenser 223, a drying filter 224, a capillary tube 225, an evaporator 226 and a return air pipe 227 which are connected end to end in sequence to form a closed loop.

As shown in FIGS. 6, 9 to 11, the compressor 221, the condenser 223 and the filter dryer 224 are all arranged in the compressor chamber 2103, the high temperature pipeline 222 is distributed in the compressor chamber 2103 and the heat dissipation air outlet channel 2106, and the evaporator 226 is arranged in the refrigeration compartment 2104. Most of the pipe sections of the capillary tube 225 and the return air pipe 227 are located outside the compressor chamber 2103 and the refrigeration compartment 2104. Alternatively, those skilled in the art may also place the capillary tube 225 and/or the return air pipe 227 outside the compressor chamber 2103 and the refrigeration compartment 2104 as needed. All of them are arranged outside the press chamber 2103 and the refrigeration chamber 2104.

As shown in FIG. 6 and FIG. 13 to FIG. 16, the heat dissipation fan 230 is arranged in the compressor chamber 2103, the air supply fan 240 is arranged in the refrigeration chamber 2104, and the evaporation dish 250 is arranged in the heat dissipation air outlet channel 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 dish 250, so that the high-temperature pipeline 222 can heat the water in the evaporation dish 250 to promote the evaporation of the water.

As shown in FIGS. 13 to 16, in some embodiments of the present invention, a transverse gap 21071 is formed between the top plates of the compressor chamber 2103, the heat dissipation air inlet channel 2105, and the heat dissipation air outlet channel 2106 and the bottom plate of the refrigeration chamber 2104, and the transverse gap 21071 is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton). A front gap 21072 is formed between the bottom of the front side plate of the refrigeration chamber 2104 and the outer side plate of the housing 210 adjacent thereto, and the front gap 21072 is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton). A longitudinal gap 21073 is formed between the left side plate and the right side plate of the refrigeration chamber 2104 and the outer side plates of the housing 210 adjacent thereto, and the longitudinal gap 21073 is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton).

Furthermore, the top plates of the press chamber 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 insulation materials in the horizontal gap 21071, the front gap 21072 and the longitudinal gap 21073 are filled evenly and with equal thickness, thereby evenly insulating the refrigeration chamber 2104.

Optionally, the capillary tube 225 and the return air pipe 227 located outside the press chamber 2103 and the refrigeration chamber 2104 are arranged in the longitudinal gap 21073 and wrapped with insulation material. The capillary tube 225 and the return air pipe 227 are in contact with each other to exchange heat. Further, since the temperature of the heat dissipation air inlet channel 2105 is lower than that of the heat dissipation air outlet channel 2106, the capillary tube 225 and the return air pipe 227 are preferably arranged in one of the two longitudinal gaps 21073 close to the heat dissipation air inlet channel 2105.

As shown in FIGS. 14 and 15 , the refrigeration module 200 further includes a pressing plate 260 disposed between the evaporator 226 and the top plate of the refrigeration compartment 2104 , and the pressing plate 260 is used to press the evaporator 226 onto the bottom plate of the refrigeration compartment 2104 , thereby fixing the evaporator 226 in the refrigeration compartment 2104 at an angle.

In some embodiments of the present invention, the evaporator 226 is configured to be inclined upward in a front-to-rear direction, and the angle between the evaporator 226 and the horizontal plane ranges from 8° to 45°, for example, 8°, 12°, 15°, 20°, 30°, 45°, etc.

In addition, in other embodiments of the present invention, those skilled in the art may also place the evaporator 226 horizontally as needed, provided that the projection area of the evaporator 226 on the horizontal plane is larger than the projection area on the vertical plane.

Continuing to refer to FIG. 14 and FIG. 15 , in some embodiments of the present invention, the bottom plate of the refrigeration chamber 2104 is provided with a drainage hole 2108 below the front portion of the evaporator 226. The refrigeration module 200 further includes a drainage pipe 270 that is connected to the drainage hole 2108 and extends from top to bottom into the evaporation dish 250, so that the drainage pipe 270 can quickly discharge the defrost water in the refrigeration chamber 2104 into the evaporation dish 250.

14 and 15 , the air supply fan 240 is located between the evaporator 226 and the air supply port 2101 on the air flow path, and the evaporator 226 and the air supply fan 240 are both arranged obliquely in the refrigeration compartment 2104 .

As shown in FIG. 14 , the bottom plate of the refrigeration compartment 2104 includes an evaporator support section 21041 and a fan support section 21042 extending obliquely backward and upward at the rear side of the drain hole 2108, and the inclination angle of the air supply fan support section 21042 is greater than the inclination angle of the evaporator support section 21041, so that the inclination angle of the air supply fan 240 is greater than the inclination angle of the evaporator 226. Preferably, the air supply fan 240 is a centrifugal fan. The distance between the position on the top surface of the centrifugal fan aligned with the rotating shaft of its impeller and the top plate of the refrigeration compartment 2104 is not less than 30 mm, so as to reduce the wind resistance of the centrifugal fan when inhaling air.

The spacing is the distance in the direction in which the axis of the impeller extends.

In addition, those skilled in the art may also set the air supply fan 240 to any other feasible fan, such as a cross-flow fan, an axial flow fan, etc., as needed.

As shown in Figures 14 and 16, the rear section 21043 of the top plate of the refrigeration compartment 2104 is tilted downward from front to back, and the air supply port 2101 is formed on the rear section 21043. It is not difficult to see from the figure that the air supply port 2101 is located in the center of the rear section 21043, and the air supply port 2101 is a rectangular opening extending laterally. It can be seen from Figures 14 and 15 that the section of the top plate of the refrigeration compartment 2104 located in front of the air supply port 2101 extends forward in the horizontal direction.

Correspondingly, the inlet end of the air supply duct 130 on the cabinet module 100 is also tilted so that the inlet end of the air supply duct 130 is parallel to the rear section 21043 .

Referring back to FIG. 5 , in some embodiments of the present invention, the top of the front side plate of the housing 210 has a recessed structure 211 that is recessed inward, the bottom wall of the recessed structure 211 is inclined upward and backward from bottom to top, and the front return air outlet 21021 is formed on the bottom wall of the recessed structure 211. Preferably, the front return air outlet 21021 is a strip-shaped opening extending laterally.

Optionally, a spoiler (not marked in the figure) is provided on the front side plate of the housing 210. The top of the front return air outlet 21021 tilts backward from top to bottom.

As shown in Fig. 5, Fig. 9 and Fig. 16, the connection between the top side plate and the left side plate of the housing 210 is set as an inclined surface, and the connection between the top side plate and the right side plate of the housing 210 is also set as an inclined surface. The side return air vent 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 cabinet module 100 is also tilted so that the outlet end of the return air duct 140 is parallel to the right side slope of the shell 210 .

In addition, in some other embodiments of the present invention, those skilled in the art may also, as needed, dispose the side return air outlet 21022 in the middle or rear of the shell 210; and form the side return air outlet 21022 on the left inclined surface of the shell 210 as needed, and dispose the first air outlet 10111 and the return air duct 140 on the box module 100 on the left side of the box module 100.

In some other embodiments of the present invention, those skilled in the art may further provide side return air ports 21022 on the left and right inclined surfaces of the housing 210, and provide first air outlets 10111 and return air ducts 140 on the left and right sides of the cabinet module 100, as required. Optionally, the two first air outlets 10111 and the two return air ducts 140 correspond to the same storage compartment, or each first air outlet 10111 and each return air duct 140 correspond to one storage compartment.

In some other embodiments of the present invention, those skilled in the art may, as needed, set a slope on only one of the joints between the top side panel and the left side panel of the shell 210 and the joints between the top side panel and the right side panel of the shell 210, and set the side return air outlet 21022 on the slope.

As shown in FIGS. 16 to 18 , in some embodiments of the present invention, the housing 210 further includes an air guide member 280 for connecting the side return air port 21022 with the refrigeration compartment 2104. Specifically, the air guide member 280 penetrates the longitudinal gap 21073 , and the air outlet end of the air guide member 280 extends to the front side of the evaporator 226 .

In some embodiments of the present invention, the side return air port 21022 may be connected to the air inlet end of the air guiding component 280 , or may be formed on the air inlet end of the air guiding component 280 .

As shown in Figures 17 and 18, the air guide member 280 includes a transverse opening portion 281 and a longitudinal opening portion 282. The top of the transverse opening portion 281 is provided with an air inlet, and the opening direction of the air inlet is inclined upward in the transverse direction (the left-right direction of the refrigeration module 200). The air inlet is also set to a rectangular opening or a strip opening extending in the front-to-back direction. An air outlet is set on one side of the longitudinal opening portion 282 in the transverse direction, and the air outlet is set to a rectangular opening or a strip opening extending in the vertical direction. The air outlet of the air guide member 280 extends to the front side of the evaporator 226, so that the airflow blown out from the air guide member 280 is all blown to the front side of the evaporator 226.

As shown in Figures 10 and 11, in the left and right directions of the refrigeration module 200, the compressor 221, the heat dissipation fan 230 and the condenser 223 are arranged in sequence between the heat dissipation air outlet channel 2106 and the heat dissipation air inlet channel 2105, and the heat dissipation fan 230 and the condenser 223 are arranged closely to reduce the lateral size of the refrigeration module 200.

Optionally, the refrigeration module 200 further includes a fixed shell 201 disposed in the compressor chamber 2103, and the heat dissipation fan 230 and the condenser 223 are both fixedly connected to the fixed shell 201. Further optionally, at least a portion of at least one of the heat dissipation fan 230 and the condenser 223 is embedded in the fixed shell 201. Preferably, at least a portion of each of the heat dissipation fan 230 and the condenser 223 is embedded in the fixed shell 201 so that the airflow flowing through the heat dissipation fan 230 flows through the condenser 223, thereby improving the heat dissipation efficiency of the heat dissipation fan 230 to the condenser 223.

As can be seen from FIG. 10 and FIG. 12 , the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel There is a gap between each bottom plate 2106 and the supporting surface (such as the ground or floor).

As shown in FIGS. 10 to 13 , the heat dissipation air inlet channel 2105 includes a plurality of front air inlets 21051 formed on the front side plate of the housing 210, so that the outside air can enter the heat dissipation air inlet channel 2105 from the plurality of front air inlets 21051. Further, the heat dissipation air inlet channel 2105 also includes a plurality of bottom side air inlets 21052 formed on the bottom plate of the heat dissipation air inlet channel 2105, so that the outside air can enter the heat dissipation air inlet channel 2105 through the gap below the heat dissipation air inlet channel 2105 and the plurality of bottom side air inlets 21052.

It is understood by those skilled in the art that, since the heat dissipation air inlet channel 2105 has a plurality of front air inlets 21051 located at the front side thereof and a plurality of bottom air inlets 21052 located at the bottom side thereof, the air inlet capacity of the heat dissipation air inlet channel 2105 is improved and the wind resistance is reduced. This not only avoids the problem of poor air inlet due to the limitation of the front side plate area of the heat dissipation air inlet channel 2105 when the heat dissipation air inlet channel 2105 only has a plurality of front air inlets 21051; it also avoids the problem of the bottom air inlet 21052 being blocked due to the accumulation of dust, lint and other debris at the bottom air inlet 21052 when the heat dissipation air inlet channel 2105 only has a plurality of bottom air inlets 21052, thereby preventing the heat dissipation air inlet channel 2105 from obtaining sufficient air.

Continuing to refer to FIGS. 10 to 13 , the heat dissipation air outlet channel 2106 includes a plurality of front air outlets 21061 formed on the front side plate of the housing 210, so that the hot air in the heat dissipation air inlet channel 2105 can flow out to the outside through the plurality of front air outlets 21061. Optionally, the heat dissipation air outlet channel 2106 includes a plurality of bottom side air outlets (not shown in the figure) formed on the bottom plate thereof.

As shown in FIG. 12 , the housing 210 further includes a wind shield 215 disposed on the bottom side of the bottom plate of the compressor chamber 2103 , and the wind shield 215 is used to prevent the bottom air inlet 21052 from sucking in hot air blown out from the front air outlet 21061 .

Continuing to refer to FIG. 10 to FIG. 12 , the bottom plate of the compressor chamber 2103 is provided with a plurality of bottom air inlets 21031 on the windward side of the condenser 223, and the bottom plate of the compressor chamber 2103 is provided with a plurality of bottom air outlets 21032 on the side of the heat dissipation fan 230 away from the condenser 223. In addition, the plurality of bottom side air inlets 21052 and the plurality of bottom air inlets 21031 are located on one side of the wind shield 215, and the plurality of bottom air outlets 21032 are located on the other side of the wind shield 215. Based on this, it can be understood by those skilled in the art that the outside air can also enter the compressor chamber 2103 through the bottom air inlet 21031, and a part of the hot air in the compressor chamber 2103 will flow to the outside from the bottom air outlet 21032.

It can be seen from Figures 10 to 12 that in some embodiments of the present invention, a portion of the multiple silo bottom air outlets 21032 are located below the compressor 221, and another portion of the multiple silo bottom air outlets 21032 are located on the front side of the compressor 221.

As shown in FIGS. 10 to 12 , 14 and 15 , a plurality of bottom air outlets 21032 located at the front side of the compressor 221 are adjacent to the evaporating dish 250 .

It is understood by those skilled in the art that the airflow blocked by the rear side panels of the evaporating dish 250 can be reflected to the multiple bottom air outlets 21032 on the front side of the compressor 221, and then flow to the outside from the multiple bottom air outlets 21032 (as shown in Figures 14 and 15). Compared with the structure without the bottom air outlet 21032 on the rear side of the evaporating dish 250, this structure can effectively avoid the blocking effect of the rear side panels of the evaporating dish 250 on the airflow, and thus effectively avoid the airflow from cyclones at the rear side panels of the evaporating dish 250. Therefore, in some embodiments of the present invention, the obstruction of the rear side panels of the evaporating dish 250 on the airflow can be effectively eliminated, and the corresponding noise can be eliminated.

In other embodiments of the present invention, those skilled in the art may also arrange the multiple silo bottom air outlets 21032 into any other feasible form as needed, for example, arranging the multiple silo bottom air outlets 21032 on the front side, right side and bottom side of the compressor 221, or arranging them on the compressor 221. The front and/or right side of 221.

As shown in FIGS. 10 and 11 , in some embodiments of the present invention, the structure of the evaporating dish 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 sides of the evaporating dish 250 and the heat dissipation air outlet channel 2106 that are opposite to each other are parallel, so that the evaporating dish 250 can cover the entire heat dissipation air outlet channel 2106 as much as possible, thereby increasing the evaporation area of the evaporating dish 250 and improving the evaporation rate of water in the evaporating dish 250.

Optionally, the size of the evaporating dish 250 in the front-to-back direction is greater than the size of the evaporating dish 250 in the left-to-right direction, so that the evaporating dish 250 has a sufficient length on the path of air flow in the heat dissipation air outlet channel 2106, thereby increasing the contact time between water in the evaporating dish 250 and the airflow, and improving the evaporation rate of the water in the evaporating dish 250.

Furthermore, the width of the front portion of the evaporating dish 250 gradually decreases from the back to the front, and the width of the front portion of the heat dissipation air outlet channel 2106 also gradually decreases from the back to the front, so that the flow area of the front portion of the heat dissipation air outlet channel 2106 gradually decreases, thereby gradually increasing the flow rate of the airflow at the front portion of the evaporating dish 250, so as to ensure the evaporation rate of the water in the front portion of the evaporating dish 250.

Those skilled in the art will appreciate that, in the heat dissipation air outlet channel 2106, since the temperature of the airflow is relatively high when it first enters the evaporating dish 250, it has a good heating effect on the water in the evaporating dish 250; however, as the airflow gradually approaches the front air outlet 21061, the airflow absorbs more and more heat from the water, and the temperature becomes lower and lower, resulting in a poorer heating effect on the water. By gradually reducing the width of the front of the evaporating dish 250 and the heat dissipation air outlet channel 2106 from back to front, the flow area in the front of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow rate of the airflow there is gradually increased, so that the airflow can overcome the effect of low temperature on the water evaporation efficiency at a high flow rate. Therefore, in some embodiments of the present invention, by gradually reducing the width of the evaporating dish 250 and the heat dissipation air outlet channel 2106 from back to front, the flow area in the front of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow rate of the airflow there is gradually increased, so that the airflow can overcome the effect of low temperature on the water evaporation efficiency at a high flow rate. The width of the front portion of the heat dissipation channel 2106 gradually decreases from the back to the front, thereby improving the evaporation efficiency of the water in the evaporation dish 250 by the airflow in the heat dissipation air outlet channel 2106 .

Furthermore, in the front-to-back direction of the refrigeration module 200, the distance between the front surface of the evaporating dish 250 and the front side plate of the shell 210 is not less than 5 mm, preferably not less than 15 mm, to ensure that there is a sufficient gap between the front surface of the evaporating dish 250 and the front side plate of the shell 210, thereby reducing the wind resistance to the airflow there.

As can be seen from Figures 12 to 14, the front air inlet 21051 and the front air outlet 21061 are both strip holes extending in the up-down direction, and the top surface of the front end of the evaporation dish 250 is located in the middle and upper part of the strip hole in the vertical direction. That is, in the up-down direction of the refrigeration module 200, the top of the front side plate of the evaporation dish 250 is located in the middle and upper part of the front air outlet 21061, so as to ensure that part of the airflow can be blown out from the front air outlet 21061 in the horizontal direction.

Furthermore, in the up and down direction of the refrigeration module 200, the minimum distance between the top surface of the evaporating dish 250 (i.e., the top of the front side plate of the evaporating dish 250) and the top wall of the heat dissipation air outlet channel 2106 is not less than 5 mm, preferably not less than 15 mm, to ensure that there is a sufficient gap between the front side plate of the evaporating dish 250 and the top wall of the heat dissipation air outlet channel 2106, thereby reducing the wind resistance to the airflow there.

As shown in FIGS. 10 , 11 , 14 and 15 , in some embodiments of the present invention, a water receiving pipe 251 extending upward from the bottom plate of the evaporating dish 250 is provided in the evaporating dish 250. The lower end of the drain pipe 270 is inserted into the water receiving pipe 251, and there is 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 through the gap and flow into the evaporating dish 250.

It is understood by those skilled in the art that since the lower end of the drain pipe 270 is inserted into the water receiving pipe 251, a small amount of water will remain in the water receiving pipe 251 after the evaporator 226 is defrosted. The water in the water receiving pipe 251 seals the bottom end of the drain pipe 270, that is, the liquid level in the water receiving pipe 251 is above the bottom end of the drain pipe 270. Those skilled in the art can further understand that, since the bottom end of the drain pipe 270 is sealed by water, the hot air in the evaporating dish 250 cannot enter the refrigeration chamber 2104 from the drain pipe 270, thereby improving the refrigeration efficiency of the refrigeration module 200.

In addition, in other embodiments of the present invention, those skilled in the art may also, as required, set a trough in the evaporating dish 250 and insert the lower end of the drain pipe 270 into the trough. Specifically, the trough is formed on the bottom plate of the evaporating dish 250 and is recessed downward, so that when the amount of water in the evaporating dish 250 is small, it can be ensured that there is water in the trough, thereby ensuring that the drain pipe 270 can be sealed by water.

So far, the cabinet module 100 and the refrigeration module 200 of the present invention have been described in detail in conjunction with the accompanying drawings. Based on the foregoing description, those skilled in the art can understand that, in the present invention, by setting the evaporator 226 to be tilted upward in the direction from front to back, the angle between the evaporator 226 and the horizontal plane is in the range of 8° to 45°, so that the evaporator 226 occupies a smaller space in the vertical direction and a smaller space in the front-to-back direction, so that the refrigeration compartment 2104 can reserve more space for arranging the air supply fan 240, and there is a sufficient gap between the air supply fan 240 and the evaporator 226, so as to avoid excessive wind resistance and affect the energy consumption of the refrigeration equipment.

Furthermore, by making the outer contours of the projections of the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane located outside the projection of the refrigeration chamber 2104 on the horizontal plane, and filling the transverse gap 21071, the front gap 21072 and the longitudinal gap 21073 outside the refrigeration chamber 2104 with insulation materials, the top plates of the press chamber 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, and ensuring that The refrigeration compartment 2104 does not leak cold air and also makes the structure of the refrigeration module 200 more compact.

Furthermore, by arranging the evaporating dish 250 in the heat dissipation air outlet channel 2106 , the evaporating dish 250 can utilize the heat of the entire press chamber 2103 to heat the water therein, thereby increasing the evaporation rate of the water in the evaporating dish 250 .

Furthermore, by extending the drain pipe 270 from top to bottom into the evaporating dish 250, the defrosted water in the refrigerating chamber 2104 can be quickly discharged into the evaporating dish 250. By inserting the lower end of the drain pipe 270 into the water receiving pipe 251, a small amount of water will be stored in the water receiving pipe 251 after the evaporator 226 is defrosted, and the bottom end of the drain pipe 270 is liquid-sealed. It can be understood by those skilled in the art that, since the bottom end of the drain pipe 270 is sealed by water, the hot air in the evaporating dish 250 cannot enter the refrigerating chamber 2104 from the drain pipe 270, thereby improving the refrigeration efficiency of the refrigeration module 200.

At the same time, the above structure of the refrigeration module 200 also makes the entire refrigeration module 200 flatter, leaving more space for the box module 100 thereon.

So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and/or technical principles of the present invention will fall within the protection scope of the present invention.
