[0024] The present invention will be described in detail below with reference to various embodiments shown in the accompanying drawings.

[0025] In various drawings of the present invention, for the sake of convenience of illustration, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0026] It should be understood that although the terms first, second, etc. may be used in this document to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0027] See also Figures 1 to 4A refrigeration device 100 provided in one embodiment of the present invention comprises a box body 1 and a door body, wherein the box body 1 defines a refrigeration space for storing and refrigerating articles, and the door body is assembled to the box body 1 and can rotate relative to the box body 1 to open or close the refrigeration space. The refrigeration device 100 can be a refrigerator, a freezer, a wine cabinet, etc.

[0028] For ease of description, in this embodiment, the refrigeration device 100 is placed on the ground or on a base as an example for description. When the door is closed, the user faces the door as a reference, and the direction from the door toward the box body 1 is defined as the direction from front to back. The direction of the box body 1 relative to the ground or the base is up, and the opposite direction is down. When the user faces the door from the front, the left and right sides of the user are defined as left and right, respectively.

[0029] See also Figure 3 to Figure 4 The box body 1 includes a rear wall 11 and a pair of side walls connected to the rear wall 11. The rear wall 11 is provided with an exhaust port 111, a return air port 112 and a vent 113. Specifically in this embodiment, the pair of side walls includes a left side wall 12 and a right side wall 13 which are arranged opposite to each other. The left side wall 12 is connected to the left end of the rear wall 11, and the right side wall 13 is connected to the right end of the rear wall 11.

[0030] The box body 1 defines a press chamber 2 located at the rear lower portion thereof, and the press chamber 2 defines a built-in space.

[0031] The refrigeration device 100 also includes a first condenser 3 and a wind shield 4, which are both arranged on the rear side of the rear wall 11. The wind shield 4 divides the rear space of the box body 1 into a first zone and a second zone. The first condenser 3, the exhaust port 111 and the return air port 112 are located in the first zone, and the vent 113 is located in the second zone. The exhaust port 111, the return air port 112 and the vent 113 are all connected to the built-in space.

[0032] By arranging the first condenser 3 in the first zone, not only can the pipeline of the condenser be extended, the laying area of ​​the condenser be increased, and the heat dissipation efficiency be improved, but also the space of the compressor chamber 2 can be made smaller, which is beneficial to increase the volume of the refrigeration space and improve the volumetric ratio of the refrigeration device 100; further, by arranging the wind shield 4, the rear space of the box body 1 is divided into the first zone and the second zone, and the exhaust port 111 and the return air port 112 are located in the first zone, so that the cold air in the compressor chamber 2 can be discharged from the exhaust port 111 and flow through the first condenser 3 and then flow back into the compressor chamber 2, so as to achieve the effect of heat dissipation for the first condenser 3; the heat exchange between the compressor chamber 2 and the outside world can be further increased through the vent 113, thereby improving the heat dissipation efficiency of the compressor chamber 2.

[0033] Furthermore, the exhaust port 111 and the return air port 112 are spaced apart from each other on the left and right sides, thereby preventing the cold air discharged from the compressor compartment 2 from flowing back into the compressor compartment 2 without passing through the first condenser 3, thereby preventing the first condenser 3 from being effectively dissipated, affecting the use effect of the first condenser 3, and increasing energy consumption.

[0034] Furthermore, the distance between the air outlet 111 and the first condenser 3 is smaller than the distance between the air return port 112 and the first condenser 3. In this way, the cold air discharged from the air outlet 111 can flow to the first condenser 3 as quickly as possible to dissipate heat therefrom.

[0035] Specifically in this embodiment, the exhaust port 111 is located above the return air port 112, and the first condenser 3 is at least partially located above the exhaust port 111. Specifically, the first condenser 3 can be completely located above the exhaust port 111, or a part of the first condenser 3 can be located at the exhaust port 111 and the other part can be located above the exhaust port 111.

[0036] In this embodiment, the vent 113 and the return air port 112 are arranged at intervals on the left and right. On the one hand, it can avoid the vent 113 and the return air port 112 being too close to each other, resulting in the air path being too short, and thus failing to effectively dissipate the heat of the refrigeration components in the compressor compartment 2. On the other hand, the space on the rear wall 11 can be reasonably utilized to increase the area of ​​the vent 113 and the return air port 112 as much as possible within the limited space.

[0037] See also Figure 3 to Figure 4 In this embodiment, the windshield 4 includes a first section 41, a second section 42 and a third section 43 connected in sequence, the first section 41 is located below the return air port 112, the third section 43 is located above the vent 113 and below the exhaust port 111, the second section 42 connects the first section 41 and the third section 43, and the second section 42 is located between the return air port 112 and the vent 113. In this way, the rear space of the box body 1 can be divided into the first area and the second area by the windshield 4, and the exhaust port 111, the return air port 112 and the first condenser 3 are all located in the first area, and the vent 113 is located in the second area, and the windshield 4 can block the air cross-flow between the first area and the second area, so as to directional guide the flow of hot and cold air, and the segmented structural design allows the windshield 4 to be flexibly set according to the positions of the exhaust port 111, the return air port 112 and the vent 113, so as to achieve a better windshield effect.

[0038] Preferably, the left end of the wind shielding member 4 is connected to the left side wall 12, and the right end of the wind shielding member 4 is connected to the right side wall 13, so as to improve the wind shielding effect.

[0039] Preferably, the first section 41 and the third section 43 both extend transversely to facilitate processing and save materials.

[0040] Furthermore, the rear wall 11 includes a cover 114 and a back plate 115 located above the cover 114, the cover 114 is located at the rear of the built-in space, the return air port 112 and the vent 113 are both provided on the cover 114, the exhaust port 111 is provided on the back plate 115, and the first condenser 3 is provided on the back plate 115. The setting of the cover 114 can play a role in blocking the wind, realize the limitation of the wind path in the compressor chamber 2, make the cold air flow in a directional manner, improve the heat exchange efficiency, and also play a protective role such as dust and rodent prevention.

[0041] In this embodiment, the wind shield 4 is disposed at the rear side of the housing 114, thereby effectively isolating the vent 113 from the exhaust port 111 and the return port 112. Of course, in other embodiments, the third section 43 may also be disposed on the back plate 115, as long as the third section 43 isolates the vent 113 from the exhaust port 111.

[0042] See also Figures 5 and 6 Furthermore, a compressor 21 and a second condenser 22 are arranged at intervals on the left and right sides of the compressor compartment 2, and a return air port 112 is arranged at the cover 114 corresponding to the compressor 21, so that the hot air after the heat is dissipated in the first condenser 3 can flow into the compressor compartment 2 from the return air port 112 and further dissipate the heat of the compressor 21, and a vent 113 is arranged at the cover 114 corresponding to the second condenser 22.

[0043] In this embodiment, the compressor 21 and the second condenser 22 are both located in the built-in space, the compressor 21 is located on the right side of the second condenser 22, and the second condenser 22 is located on the left side of the compressor 21. Correspondingly, the return air port 112 is located on the right side of the vent 113, the vent 113 is located on the left side of the return air port 112, and the exhaust port 111 is also located on the left side of the return air port 112. In other embodiments, the arrangement positions of the compressor 21 and the second condenser 22 can also be interchanged, and correspondingly, the positions of the return air port 112, the vent 113, and the exhaust port 111 are also adjusted accordingly.

[0044] Furthermore, a fan 23 is provided in the compressor chamber 2, and the fan 23 is arranged front and rear opposite to the second condenser 22. In this embodiment, the fan 23 is arranged behind the first condenser 3, and the air outlet 25 of the fan 23 is connected to the exhaust port 111, so that the air in the compressor chamber 2 can be discharged to the first condenser 3 through the exhaust port 111 as soon as possible by means of the fan 23, so as to dissipate heat for the first condenser 3 and improve the heat dissipation efficiency.

[0045] See also Figure 7 Furthermore, an air inlet 24 and an air outlet 25 are also provided at the bottom of the compressor chamber 2. The air inlet 24 and the air outlet 25 are arranged at intervals on the left and right. The air inlet 24 is arranged on the side close to the second condenser 22, and the air outlet 25 is arranged on the side close to the compressor 21.

[0046] Specifically, the compressor chamber 2 also includes a bottom plate 26 located below the built-in space, the air inlet 24 and the air outlet 25 are both arranged on the bottom plate 26, and the air inlet 24 is arranged on the side of the bottom plate 26 close to the second condenser 22, and the air outlet 25 is arranged on the side of the bottom plate 26 close to the compressor 21.

[0047] See also Figure 1 to Figure 2 Furthermore, the refrigeration device 100 also includes a cabinet 5, which defines a storage space, and the box body 1 can be built into the storage space. The cabinet 5 includes a rear panel 51, a top panel 52, and a pair of side panels 53 arranged opposite to each other on the left and right sides. The rear panel 51 is located at the rear of the storage space, and the top panel 52 is located above the storage space. The rear ends of the pair of side panels 53 are respectively connected to the left and right ends of the rear panel 51.

[0048] When the cabinet 1 is built into the accommodation space, the wind shield 4 is connected to the rear plate 51. In this way, the range of the first area and the second area can be defined between the rear plate 51 of the cabinet 5 and the rear wall 11 of the cabinet 1, thereby realizing the space limitation of the wind path, so as to achieve comprehensive heat dissipation of the first condenser 3 and improve the heat dissipation efficiency of the first condenser 3.

[0049] Preferably, the wind shield 4 is a flexible member, which can avoid damage to the cabinet 5 on the one hand, and improve the sealing between the wind shield 4 and the rear plate 51 on the other hand, thereby improving the isolation effect between the first area and the second area.

[0050] Preferably, the left and right ends of the wind shield 4 are respectively connected to a pair of side panels 53 of the cabinet 5 to prevent the cold and hot air in the first zone and the second zone from flowing into each other and affecting the heat dissipation effect.

[0051] Furthermore, the cabinet 5 also includes an air inlet duct 54 and an air outlet duct 55 located below the box body 1. The air inlet duct 54 and the air outlet duct 55 are isolated from each other. The air inlet duct 54 connects the air inlet 24 and the external space of the cabinet 5, and the air outlet duct 55 connects the air outlet 25 and the external space of the cabinet 5.

[0052] The cabinet 5 also includes a support plate located in the accommodating space and a partition plate 56 located below the support plate. The box body 1 can be placed above the support plate, and the air inlet duct 54 and the air outlet duct 55 are located below the support plate. The partition plate 56 separates the air inlet duct 54 from the air outlet duct 55.

[0053] Preferably, the air inlet 24 and the air outlet 25 are both located at the front end of the bottom plate 26, and in the front-to-back direction, the vent 113 is arranged corresponding to the air inlet 24. In this way, the vent 113 can also be used as an air inlet, and the vent 113 and the air inlet 24 share the same air inlet duct 54, that is, the vent 113 connects the air inlet duct 54 and the built-in space, and the air inlet 24 also connects the air inlet duct 54 and the built-in space, so that the two air inlets can be simultaneously inlet, thereby improving the heat dissipation efficiency in the compressor chamber 2.

[0054] In this embodiment, no air vents are provided on the top plate 52 of the cabinet 5, thereby preventing part of the cold air exhausted from the exhaust vent 111 from flowing out from the top plate 52 of the cabinet 5 to the external environment. The cold air exhausted from the exhaust vent 111 can circulate between the rear wall 11 and the rear plate 51, and then all flow back into the compressor chamber 2 from the return air vent 112. The cabinet 5 can also be made higher without reserving space between the top of the cabinet 5 and the ceiling, thereby increasing the aesthetics, or utilizing the space above the cabinet 5 to improve space utilization.
