[0028] Refer to Figure 1 , an embodiment of the present utility model provides a refrigeration device 1000, specifically a commercial freezer, which is applied to supermarkets, hospitals, etc. The refrigeration device 1000 includes a cabinet 200 and a press cabin 100 connected to the cabinet 200. Among them, the cabinet 200 is internally provided with a plurality of layers of shelves arranged in the height direction for storing items. The press cabin 100 is located at the bottom of the cabinet 200 in the height direction and is connected to the air duct structure inside the cabinet 200 through a pipeline.

[0029] In one embodiment, the press cabin 100 includes a first cover plate 110 and a second cover plate 120 that are opposite and parallel to each other along a first direction. In an actual scenario, the first direction is the front-back direction, and the first cover plate 110 and the second cover plate 120 are the front cover plate and the rear cover plate respectively.

[0030] Combined with Figures 2-3 As shown, the press cabin 100 includes a bottom wall 130 and a top wall 140 that are opposite and parallel to each other along the height direction, and a first side wall 150 and a second side wall 160 that are opposite and parallel to each other along a second direction. The second direction is perpendicular to the first direction, and the first direction and the second direction are horizontal directions.

[0031] The first cover plate 110, the second cover plate 120, the bottom wall 130, the top wall 140, the first side wall 150, and the second side wall 160 enclose a receiving space 101.

[0032] In one embodiment, the refrigeration device 1000 includes a condenser 10, a heat dissipation fan, and a compressor 30 that are sequentially arranged in the receiving space 101 along the first direction for obtaining condensed liquid. The compressor 30 is used to compress the refrigerant with low temperature and low pressure into a hot gas with high temperature and high pressure, and the condenser 10 is used to condense the hot gas with high temperature and high pressure into a high-pressure liquid. The heat dissipation fan is used to disperse the heat in the press cabin 100.

[0033] The refrigeration device 1000 includes a partition plate 40 that divides the press cabin 100 into a first space 102 and a second space 103 along the first direction. Specifically, the receiving space 101 is divided into the first space 102 and the second space 103 along the first direction. The condenser 10 is arranged in the first space 102, and the compressor 30 is arranged in the second space 103.

[0034] Combined with Figures 8-10 As shown, the condenser 10 and the compressor 30 are arranged on the bottom wall 130. The condenser 10 is close to the first cover plate 110, and the compressor 30 is close to the second cover plate 120. The first cover plate 110 has an air inlet, and the air inlet communicates with the air inlet side of the condenser 10. The air outlet side of the condenser 10 faces the partition plate 40, and the bottom wall 130 is provided with an air outlet 131 at the position corresponding to the air outlet side of the condenser 10 to quickly discharge the heat generated by the condenser 10 to the outside.

[0035] The air inlet of the first cover plate 110 communicates with the first space 102 for introducing air into the first space 102, and thus communicates with the air inlet side of the condenser 10. The condenser 10 is located between the first cover plate 110 and the partition plate 40.

[0036] The second cover plate 120 is provided with an air outlet 121. The compressor 30 is located between the second cover plate 120 and the partition plate 40, and the heat of the compressor 30 can be discharged through the air outlet 121.

[0037] In this way, on the one hand, the cold and hot airflows of the condenser 10 are isolated from each other to prevent the condensation heat in the compressor compartment 100 from leaking out from the first cover plate 110 and entering the air inlet side of the condenser 10, resulting in a reduction in the efficiency of the condenser 10.

[0038] On the other hand, the airflows of the condenser 10 and the compressor 30 are isolated. The compressor 30 does work to generate heat, and the temperature of the surrounding airflows is relatively high. They flow in the second space 103 to the partition plate 40. Due to the blocking of the partition plate 40, the hot airflows brought by the compressor 30 cannot reach the first space 102, thus not affecting the condenser 10.

[0039] In one embodiment, the cooling fan is fixed on the partition plate 40, and the central axis of the cooling fan in the first direction is biased towards one side of the compressor 30.

[0040] Combined with Figures 6-7 As shown, the cooling fan is arranged on the air outlet side of the condenser 10 to dissipate the heat in the second space 103, and the central axis of the cooling fan is eccentrically arranged with respect to the compressor 10.

[0041] The "one side of the compressor 30" mentioned above is the side with a higher temperature of the compressor 30. It can be understood that the compressor 30 generates heat when doing work. Usually, one side of the compressor 30 will generate hot gas with high temperature and pressure, thus having a higher temperature, while the other side has a relatively lower temperature. Therefore, the cooling fan is biased towards the side of the compressor 30 with a higher temperature, which is beneficial to taking away the heat of the compressor 30 and reducing the heat load in the compressor compartment 100.

[0042] Specifically, the cooling fan blows air towards the second space 103, and the hot air in the second space 103 can be discharged through the above air outlet 121.

[0043] In one embodiment, the central axis of the cooling fan is biased towards one side of the compressor 10 in the second direction, and the second direction is the horizontal left - right direction. The side of the compressor 30 with a higher temperature is in the horizontal direction. If the cooling fan and the compressor 10 need to be offset in the vertical direction, it will result in a large occupation of space in the vertical direction.

[0044] In one embodiment, the refrigeration device 1000 includes a power supply module 50 arranged in the compressor compartment 100, and the power supply module 50 is located on the other side of the compressor 10 in the second direction. Combined with Figure 9As shown, the power supply module 50 is disposed on the first side wall 150, and the central axis of the cooling fan is biased towards the second side wall 160. The side of the compressor 10 with a higher temperature faces the second side wall 160, and the side of the compressor 10 with a lower temperature faces the first side wall 150. Therefore, the influence of the heat of the compressor 10 on the power supply module 50 is reduced.

[0045] It can be understood that other modules and devices in the compressor compartment 100 can also be preferentially disposed near the first side wall 150.

[0046] In one embodiment, a wind guiding portion 41 is disposed on the partition plate 40 along a side biased towards the compressor 10 in the second direction. The partition plate 40 includes a fixing hole 410 disposed on the wind guiding portion 41, and the cooling fan is fixed to the fixing hole 410. Thus, the wind on the air inlet side of the condenser 10 can enter the second space 103 through the wind guiding portion 41 and the cooling fan to dissipate heat from the second space 103.

[0047] The fixing hole 410 is disposed at the central position of the wind guiding portion 41, and the central axis of the wind guiding portion 41 coincides with the central axis of the cooling fan. The central position of the wind guiding portion 41 is also biased towards the side of the compressor 10, which is beneficial for the wind to converge at the wind guiding portion 41 and then blow towards the side of the compressor 10 with a higher temperature.

[0048] In one embodiment, the wind guiding portion 41 is in a gradually shrinking trumpet shape along the direction from the condenser 10 towards the compressor 30, and the surface of the wind guiding portion 41 exposed to the second space is a smooth surface.

[0049] In other words, the outer diameter dimension of the wind guiding portion 41 is large on the side close to the first cover plate 110, and the outer diameter dimension is small at the fixing hole 410 away from the first cover plate 110, which is beneficial for the wind from the first cover plate 110 to converge at the fixing hole 410 and then be blown by the cooling fan towards the second space 102. The smooth surface is beneficial for gas flow.

[0050] In one embodiment, the periphery of the partition plate 40 abuts against the inner wall surface of the compressor compartment 100, and a wind blocking portion 42 is disposed on the surface of the partition plate 40 exposed to the first space 102, which is beneficial for blocking the diffusion of the hot air flow in the first space 102 into the second space 103.

[0051] Specifically, the partition plate 40 is located between the first cover plate 110 and the second cover plate 120 along the first direction. The periphery of the partition plate 40 is respectively provided with abutting plates that are attached and abut against the bottom wall 130, the top wall 140, the first side wall 150, and the second side wall 160 of the compressor compartment 100. Thus, the hot air flow from the compressor 30 is blocked. Further, the surface of the partition plate 40 exposed to the first space 102 is provided with grid-like protrusions instead of a smooth surface, which has the function of absorbing and blocking the air flow.

[0052] The refrigeration device 1000 includes a water receiving tray 60 disposed between the compressor 30 and the heat dissipation fan. The water receiving tray 60 is fixed to the bottom wall 130 of the compressor compartment 100. Condensate from the air duct mechanism is connected to the water receiving tray 60 through a pipe. The water receiving tray 60 is disposed close to the compressor 30 to absorb the heat of the compressor.

[0053] In one embodiment, in combination with Figure 2 、 4 As shown in FIG. -5, the first cover plate 110 includes a first part 111, a second part 112, and a spaced part formed between the outer periphery of the first part 111 and the inner periphery of the second part 112 along a first direction. The air inlet includes a second air inlet 1120 formed in the second part 112 and a first air inlet 113 formed in the spaced part and blocked along the first direction.

[0054] The first air inlet 113 is hiddenly disposed between the first part 111 and the second part 112, having better aesthetics; the first air inlet 113 and the second air inlet 1120 are superimposed and cooperate to intake air, increasing the air intake volume.

[0055] The first part 111 is rectangular, the second part 112 is rectangular, the second part 112 has a hollow opening corresponding to the first part 111 along the first direction. The hollow opening communicates with the accommodation space 101. The first air inlet 113 communicates with the hollow opening. The first air inlet 113 is located around the hollow opening and perpendicular to the hollow opening, so that the first air inlet 113 is in a surrounding shape.

[0056] Specifically, the first part 111 is a rectangular plate, the second part 112 is a hollow rectangular outer frame. The first part 111 is exactly located at the hollow opening of the second part 112. Viewed along the first direction, the first part 111 covers the hollow opening, so that the first part 111 and the second part 112 present as a whole rectangular plate. The first air inlet is hiddenly located between the first part 111 and the second part 112, having high aesthetics.

[0057] The outer periphery of the first part 111 is rectangular, the inner periphery of the second part 112 is rectangular, and the first air inlet 113 is also connected into an annular rectangle, increasing the air intake volume.

[0058] The second part 112 includes a front end face 1121 and a recessed area 1122 formed by recessing from its front end face 1121 in the first direction. The hollow opening is formed in the recessed area 1122. The first part 111 is disposed in the recessed area 1122 and is spaced from the hollow opening by a distance in the first direction. Specifically, the front end face of the second part 112 is the front end face.

[0059] In this way, the first part 111 is misaligned with the recessed area 1122 in the first direction, so that a spaced portion is formed between the first part 111 and the recessed area 1122 in the first direction, thereby forming a first air inlet 113 located between the first part 111 and the recessed area 1122.

[0060] In one embodiment, the spaced portion includes a plurality of connecting ribs 114. The connecting ribs 114 extend in the first direction so as to connect the first part 111 and the recessed area 1122 in the first direction. In this way, the first part 111 and the second part 112 are integrally formed, which is convenient for installation and disassembly.

[0061] Viewed in the first direction, the connecting ribs 114 are located between the first part 111 and the recessed area 1122. The first part 111 can also cover the connecting ribs 114, which has better aesthetics.

[0062] Wherein, the front end face of the first part 111 coincides with the front end face 1121 of the second part 112. In other words, the front end face of the first part 111 does not protrude from the front end face of the second part 112 in the first direction.

[0063] In one embodiment, the second part includes side walls 1123 located around the front end face 1121 and extending in the first direction. The side walls 1123 are disposed away from the first part. The second air inlet 1120 is disposed on the side walls 1123.

[0064] The side walls 1123 are formed by vertically bending backward from the front end face 1121. The side walls 1123 are equivalent to the edging of the second part 112. The side walls 1123 located around can be respectively connected to the bottom wall 130, the top wall 140, the first side wall 150 and the second side wall 160 to form the accommodation space 101. A plurality of the second air inlets 1120 are also arranged around, forming air intake around, cooperating with the first air inlet 113, increasing the air intake volume and improving the heat dissipation effect.

[0065] Each side wall 1123 is provided with a plurality of strip-shaped second air inlets 1120. The plurality of second air inlets 1120 are arranged at intervals. Each strip-shaped second air inlet 1120 extends in the first direction. Viewed in the first direction, the second air inlets 1120 cannot be seen either, which has better aesthetics.

[0066] The beneficial effects of the present utility model are as follows: The partition plate 40 separates the compressor 30 and the condenser 10, preventing the hot air of the compressor 30 from rebounding to the condenser 10 and affecting the refrigeration effect of the condenser; the heat dissipation fan is biased towards one side of the compressor 30, which is conducive to the heat dissipation fan taking away the heat from the higher temperature side of the compressor 10 and improving the heat dissipation efficiency in the compressor compartment 100.
