In some embodiments of the present utility model, the side return air outlet 21022 can communicate with the air inlet end of the air guide member 280 , and can also be formed on the air inlet end of the air guide member 280 .

As shown in FIGS. 21 and 22 , the air guide member 280 includes a transverse opening 281 and a longitudinal opening 282 , and an air inlet is provided on the top of the transverse opening 281 , and the opening direction of the air inlet is along the transverse direction (left and right direction of the refrigeration module 200 ). ) slope upward. The air inlet is also configured as a rectangular or strip-shaped opening extending along the front-to-back direction. One lateral side of the longitudinal opening 282 is provided with an air outlet, and the air outlet is configured as a rectangular opening or a bar-shaped 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 all the airflow blown out from the air guide member 280 blows to the front side of the evaporator 226 .

As shown in Fig. 6, Fig. 10, Fig. 14, Fig. 15 and Fig. 19, a rear slope 213 is provided at the connection between the rear side plate of the housing 210 and the top plate of the housing 210, and the air outlet 2101 is formed in the center of the rear slope 213 , and the air outlet 2101 is a rectangular opening extending laterally. In addition, those skilled in the art can also arrange the air outlet 2101 at other positions on the rear slope 213 as required, and arrange it in any other feasible structure. For example, the air outlet 2101 is arranged on the left side or the right side of the rear inclined surface 213, and the air outlet 2101 is arranged as an oval opening, a circular opening or a square opening.

As shown in FIG. 6 , FIG. 10 and FIG. 18 , the top plate of the housing 210 also has a top surface 214 located in front of the rear slope 213 . Preferably, the top surface 214 is arranged horizontally.

As shown in FIG. 5 , the box module 100 is provided with an upper inclined surface 151 (located above and behind the receiving chamber 102 ) that matches the rear inclined surface 213 , and the air inlet 13011 of the air supply channel 1301 is formed on the upper inclined surface 151 . The inclined surface 151 abuts against the rear inclined surface 213 so that the air supply port 2101 and the air inlet port 13011 are butted together. Further, the box module 100 is also provided with a bottom surface 152 (the top wall of the accommodating chamber 102 ) that is compatible with the top surface 214, and the top surface 214 abuts against the bottom surface 152, so that the refrigeration module 200 is carried by the top surface 214 The full gravity of the box module 100 prevents the weight of the box module 100 from pressing on the rear inclined surface 213 , thereby avoiding deformation of the edge of the air outlet 2101 and ensuring the seal between the air outlet 2101 and the air inlet 13011 .

Furthermore, although not explicitly shown in FIG. 2 , a gap is formed between the upper slope 151 and the rear slope 213 in a state where the bottom surface 152 and the top surface 214 are in contact. And at least one of the upper inclined surface 151 and the rear inclined surface 213 is attached with a compressible gasket, so that the gasket fills the gap and is extruded by the upper inclined surface 151 and the rear inclined surface 213, so that the upper inclined surface 151 and the rear inclined surface 213 are abutted together by a gasket.

Those skilled in the art can understand that by changing the edge on the back side of the refrigeration module 200 that abuts against the box module 100 into a surface (that is, the rear slope 213), the contact area of the line junction where the surface touches the opposite edge is smaller. Larger, less pressure, and less likely to deform. At the same time, the rear slope 213 , the rear side plate of the housing 210 , and the top plate of the housing 210 jointly form a triangular structure, making the structure corresponding to the rear slope 213 on the housing 210 more stable and less prone to deformation.

In some embodiments of the present utility model, the angle between the rear slope 213 and the horizontal plane is less than 45°, so as to prevent the weight of the box module 100 from pressing on the rear slope 213, thereby reducing the pressure of the air supply fan 240 in the refrigeration module 200. The pressure received in the vertical direction prevents the casing 241 of the air blower 240 from deforming; and enables the air supply port 2101 to blow out an oblique upward airflow, and make the airflow upward as much as possible.

Further, as shown in FIG. 18 , at least one rib 2131 is provided on the side plate where the rear slope 213 is located, and the rib 2131 is used to strengthen the structural strength at the edge of the air outlet 2101 . Preferably, the reinforcing rib 2131 is provided on at least a part of the circumferential edge of the air outlet 2101 on the inner side of the side plate where the rear slope 213 is located. Specifically, reinforcing ribs 2131 are respectively provided on the left side, right side and rear side of the air supply port 2101 , and the reinforcing ribs 2131 at these three positions are in contact with each other and respectively abut against the bottom wall of the cooling compartment 2104 . The bottom surfaces of the reinforcing ribs 2131 located on the left and right sides of the air outlet 2101 are inclined downward from the rear to the front to ensure contact with the bottom wall of the refrigerating compartment 2104 .

Those skilled in the art can understand that the reinforcing rib 2131 at the edge of the air supply port 2101 can support the structure at the edge of the air supply port 2101 in the vertical direction, so that the rear inclined surface 213 is subjected to the gravity of the box module 100 When squeezed, it can also have enough supporting force to avoid its deformation. Therefore, it is ensured that the casing 241 of the blower fan 240 will not be squeezed and deformed.

As shown in Figure 11 and Figure 12, in the left and right directions 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 channel 2106 and the heat dissipation air intake channel 2105, and dissipate heat The fan 230 and the condenser 223 are arranged adjacent to each other, so as to reduce the size of the refrigeration module 200 in the transverse direction.

Optionally, the refrigeration module 200 further includes a fixed shell 201 disposed in the compressor compartment 2103 , and the cooling fan 230 and the condenser 223 are both fixedly connected to the fixed shell 201 . Further optionally, at least a part of at least one of the cooling fan 230 and the condenser 223 is embedded in the fixed casing 201 . Preferably, at least a part of each of the heat dissipation fan 230 and the condenser 223 is embedded in the fixed shell 201 so that all the airflow passing 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 .

It can be seen from FIG. 11 and FIG. 13 that there are gaps between the respective bottom plates of the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 and the bearing surface (such as the ground or the floor).

As shown in Figures 11 to 14, the heat dissipation air inlet passage 2105 includes a plurality of front air inlets 21051 formed on the front side panel of the housing 210, so that the outside air can enter the heat dissipation air inlet passage 2105 from the plurality of front air inlets 21051 . Further, the heat dissipation air inlet passage 2105 also includes a plurality of bottom side air inlets 21052 formed on the bottom plate of the heat dissipation air inlet passage 2105, so that the outside air can dissipate heat from the gap below the air inlet passage 2105 and the plurality of bottom side air inlets 21052 enters the cooling air inlet channel 2105.

Those skilled in the art can understand that, since the heat dissipation air inlet passage 2105 has multiple front air inlets 21051 on its front side and multiple bottom side air inlets 21052 on its bottom side, the air inlet of the heat dissipation air inlet passage 2105 is improved. Wind capacity, reduces wind resistance. It not only avoids that when the heat dissipation air inlet channel 2105 only has a plurality of front air inlets 21051, due to the limitation of the area of the front side plate of the heat dissipation air inlet channel 2105, the air intake is not smooth; When the bottom side air inlet 21052 is closed, the bottom side air inlet 21052 is blocked due to dust, lint and other debris accumulating at the bottom side air inlet 21052, and then the heat dissipation air inlet channel 2105 cannot obtain enough air.

Continuing to refer to Fig. 11 to Fig. 14, the heat dissipation air outlet passage 2106 includes a plurality of front air outlets 21061 formed on the front side panel of the housing 210, so that the hot air in the heat dissipation air inlet passage 2105 can pass through the plurality of front air outlets. 21061 flows out to the outside world. Optionally, the heat dissipation air outlet channel 2106 includes a plurality of bottom side air outlets (not shown in the figure) formed on its bottom plate.

As shown in FIG. 13 , the housing 210 further includes a windshield 215 disposed on the bottom side of the bottom plate of the press chamber 2103 , and the windshield 215 is used to prevent the bottom side air inlet 21052 from inhaling the hot air blown from the front air outlet 21061 .

Continuing to refer to Fig. 11 to Fig. 13, the bottom plate of the compressor chamber 2103 is provided with a plurality of chamber bottom air inlets 21031 on the windward side of the condenser 223, and the bottom plate of the compressor chamber 2103 is provided on the side of the cooling fan 230 away from the condenser 223 There are multiple air outlets 21032 at the bottom of the warehouse. And a plurality of bottom side air inlets 21052 and a plurality of bin bottom air inlets 21031 are located on one side of the windshield 215 , and a plurality of bin bottom air outlets 21032 are located in the other side of the windshield 215 . Based on this, those skilled in the art can understand that the outside air can also enter the press chamber 2103 through the air inlet 21031 at the bottom of the chamber, and part of the hot air in the press chamber 2103 will flow to the outside from the air outlet 21032 at the bottom of the chamber.

It can be seen from FIG. 11 to FIG. 13 that in some embodiments of the present invention, some of the multiple warehouse bottom air outlets 21032 are located below the compressor 221, and the other part of the multiple warehouse bottom air outlets 21032 is located at The front side of the compressor 221.

As shown in FIG. 11 to FIG. 13 , FIG. 15 and FIG. 16 , a plurality of air outlets 21032 at the bottom of the bin located at the front side of the compressor 221 are adjacent to the evaporating dish 250 .

Those skilled in the art can understand that the airflow blocked by the rear side plate of the evaporating dish 250 can be reflected to the multiple compartment bottom air outlets 21032 on the front side of the compressor 221, and then flow from the multiple compartment bottom air outlets 21032 to the outside (As shown in Figure 15 and Figure 16). 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 shielding effect of the rear side plate of the evaporating dish 250 on the air flow, and then effectively prevent the air flow from being blocked by the rear side plate of the evaporating dish 250. There is a cyclone. Therefore, in some embodiments of the present invention, it is possible to effectively eliminate the hindering effect of the rear side plate of the evaporating dish 250 on the airflow, and eliminate the corresponding noise.

In other embodiments of the present utility model, those skilled in the art can also arrange the multiple warehouse bottom air outlets 21032 in any other feasible form, for example, arrange the multiple warehouse bottom air outlets 21032 on the compressor 221 The front side, the right side and the bottom side of the compressor 221, or the front side and/or the right side of the compressor 221.

As shown in Figure 11 and Figure 12, in some embodiments of the present invention, the structure of the evaporating pan 250 in the horizontal direction is compatible with the structure of the heat dissipation air outlet channel 2106 in the horizontal direction, that is, the evaporating pan 250 and the The opposite sides of the heat dissipation air outlet channels 2106 are parallel to each other, so that the evaporator 250 can cover the entire heat dissipation air outlet channels 2106 as much as possible, thereby increasing the evaporation area of the evaporator 250 and increasing the evaporation rate of water in the evaporator 250 .

Optionally, the size of the evaporating pan 250 in the front-to-back direction is larger than the dimension of the evaporating pan 250 in the left-right direction, so that the evaporating pan 250 has a sufficient length on the air flow path in the heat dissipation air outlet channel 2106, thereby increasing the size of the evaporating pan. The contact time of the water in the evaporator 250 with the airflow increases the evaporation rate of the water in the evaporating dish 250 .

Further, the width of the front part of the evaporating dish 250 gradually decreases from the back to the front, and the width of the front part of the heat dissipation air outlet channel 2106 gradually decreases from the back to the front, so that the flow area of the front part of the heat dissipation air outlet channel 2106 gradually decreases. decrease, so that the flow velocity of the airflow at the front of the evaporating dish 250 gradually increases to ensure the evaporation rate of the water in the front of the evaporating dish 250 .

Those skilled in the art can understand that, in the heat dissipation outlet channel 2106, due to the high temperature of the airflow just entering the evaporating dish 250, it has a good heating effect on the water in the evaporating dish 250; but as the airflow gradually approaches the front At the air outlet 21061, more and more heat is absorbed by the airflow by the water, and the temperature becomes lower and lower, which leads to the deterioration of its heating effect on the water. And by making the width of the front portion of the evaporating dish 250 and the heat dissipation air outlet channel 2106 gradually decrease from the back to the front, the flow area of the front portion of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow velocity of the air flow there is reduced. Gradually increase, so that the air flow can overcome the influence of low temperature on the water evaporation efficiency at a high flow rate. Therefore, in some embodiments of the present utility model, by making the width of the front portion of the evaporating dish 250 and the heat dissipation air outlet channel 2106 gradually decrease from the back to the front, the airflow in the heat dissipation air outlet channel 2106 is improved.

There is sufficient gap between the front side panels of 210 to reduce the wind resistance to the air flow there.

It can be seen from Fig. 13 to Fig. 15 that the front air outlet 21051 and the front air outlet 21061 are strip-shaped holes extending in the vertical direction, and the top surface of the front end of the evaporating dish 250 is located in the middle and upper part of the strip-shaped hole in the vertical direction. That is, in the up-and-down direction of the refrigeration module 200, the top of the front side plate of the evaporating dish 250 is located at the upper middle 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 along the horizontal direction.

Further, in the up-and-down direction of the refrigeration module 200, the minimum distance between the top surface of the evaporating pan 250 (that is, the top of the front side plate of the evaporating pan 250) and the top wall of the heat dissipation air outlet channel 2106 is not less than 5mm, preferably not The distance is 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 to reduce the wind resistance to the air flow there.

Those skilled in the art can understand that since the lower end of the drain pipe 270 is inserted into the water receiving pipe 251, there will be a small amount of water in the water receiving pipe 251 to liquid seal the bottom end of the drain pipe 270 after the evaporator 226 defrosts. , 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 pan 250 cannot enter the refrigerating compartment 2104 from the drain pipe 270 , thereby improving the cooling performance of the refrigeration module 200. efficiency.

In addition, in other embodiments of the present utility model, those skilled in the art may also set a sinker in the evaporating dish 250 as required, and insert the lower end of the drain pipe 270 into the sinker. Specifically, the sinker 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 also ensure that there is water in the sinker, thereby ensuring that the drain pipe 270 can be sealed by water. .

So far, the box module 100 and the refrigeration module 200 of the present invention have been described in detail with reference to 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 obliquely upward along the direction from front to back, the value range of the included angle between the evaporator 226 and the horizontal plane is 8 ° to 45 °, so that the evaporator 226 occupies a small space in the vertical direction, and the space occupied in the front and rear direction is also small, so that the refrigeration compartment 2104 can reserve more space for The blower fan 240 is arranged, and there is a sufficient gap between the blower fan 240 and the evaporator 226, so as to avoid excessive wind resistance and affect the energy consumption of the refrigeration equipment.

Further, by arranging the evaporating dish 250 in the heat dissipation air outlet channel 2106, the evaporating dish 250 can use the heat of the entire compressor chamber 2103 to heat the water in it, thereby increasing the evaporation rate of the water in the evaporating dish 250.

Further, by extending the drain pipe 270 from top to bottom into the evaporating pan 250 , the defrosted water in the refrigeration compartment 2104 can be quickly drained into the evaporating pan 250 . By inserting the lower end of the drain pipe 270 into the water receiving pipe 251 , there will be a small amount of water in the water receiving pipe 251 to liquid seal the bottom end of the drain pipe 270 after the evaporator 226 defrosts. Those skilled in the art can understand that, since the bottom end of the drain pipe 270 is sealed by water, the hot air in the evaporator 250 cannot enter the refrigeration compartment 2104 from the drain pipe 270, thereby improving the cooling efficiency of the refrigeration module 200 .
