[0031] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings.

[0032] 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.

[0033] 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.

[0034] Example 1

[0035] See also Figure 1 The present embodiment provides a refrigeration device 100, which can be specifically configured as a refrigerator, a freezer, a wine cabinet, etc. The refrigeration device 100 includes a door body and a box body 1, wherein the box body 1 defines a press chamber 2 and at least one storage compartment for refrigerating or freezing items, and the door body is used to open or close the storage compartment.

[0036] For ease of description, in this embodiment, the description is carried out by taking the refrigeration device 100 being placed horizontally on the ground or a base as an example. When the door is closed to close the storage compartment, the direction from the door toward the box body 1 is defined as the direction from front to back, that is, the door body is located in front of the box body 1; the direction of the refrigeration device 100 relative to the ground or the base is defined as up, and vice versa as down. When the user faces the refrigeration device 100 from the front, the left and right sides of the user are defined as left and right, respectively.

[0037] See also Figure 2 The press chamber 2 is located at the rear bottom of the box body 1, and the press chamber 2 defines a built-in space. The box body 1 includes a rear wall 13 and a pair of side walls 14 arranged opposite to each other on the left and right sides, and the rear wall 13 connects the rear ends of the pair of side walls 14.

[0038] The compressor chamber 2 includes a bottom plate 21, and a first air port 22 is formed between the rear edge of the bottom plate 21 and the rear wall 13. That is, the rear bottom of the compressor chamber 2 has a first air port 22, and the first air port 22 is formed by means of the bottom plate 21 and the rear wall 13 of the compressor chamber 2. In this way, not only can the heat in the compressor chamber 2 be discharged in time to prevent the temperature in the compressor chamber 2 from being too high, thereby affecting the refrigeration effect of the compressor 3 and the condenser 5, but also materials can be saved and costs can be reduced.

[0039] Furthermore, the rear edge of the bottom plate 21 is located in front of the rear wall 13 , that is, there is a gap between the bottom plate 21 and the rear wall 13 , which can be used for the air inlet and outlet of the compressor compartment 2 .

[0040] Preferably, the first air outlet 22 is strip-shaped and its left and right ends are respectively connected to a pair of side walls 14. Specifically, the left end of the first air outlet 22 is connected to the left side wall 14, and the right end of the first air outlet 22 is connected to the right side wall 14. This can reduce the processing difficulty and increase the area of ​​the first air outlet 22 in a limited space of the compressor chamber 2, thereby improving the heat dissipation efficiency of the compressor chamber 2.

[0041] Preferably, in the front-to-back direction, the distance between the rear edge of the bottom plate 21 and the rear wall 13 is 30-40 mm.

[0042] In this embodiment, the built-in space of the press chamber 2 is open to the rear, and the rear wall 13 is provided with an exhaust port 11 and a wind shield 12 located below the exhaust port 11. The wind shield 12 is located between the built-in space and the exhaust port 11 to prevent air mixing.

[0043] Preferably, the lower end of the rear wall 13 is located above the built-in space, so that the heat dissipation efficiency of the press chamber 2 can be further increased, the heat dissipation effect can be improved, and the production process can be simplified, saving costs.

[0044] Preferably, the wind shield 12 is horizontally placed between the built-in space of the press chamber 2 and the air outlet 11, and the air outlet 11 is wedge-shaped to facilitate the discharge of hot air in the press chamber 2.

[0045] Combination Figures 3 to 5 , a compressor 3 and a condensing fan assembly are arranged in the compressor chamber 2. The condensing fan assembly includes a condenser 5 and a centrifugal fan 6 arranged relatively to each other, and also includes a wind tube 4 sleeved on the outer periphery of the condenser 5. The condenser 5, the wind tube 4 and the centrifugal fan 6 are arranged in an integrated manner, and the wind tube 4 and the centrifugal fan 6 are sealed and connected. The wind tube 4 defines a passage connecting the air inlet of the centrifugal fan 6 and the condenser 5, and the condenser 5 is located in the passage. In other words, the centrifugal fan 6 is located downstream of the condenser 5 to promote the air to flow through the compressor 3 first and then through the condenser 5 to be discharged from the compressor chamber 2, or to flow through the condenser 5 directly without passing through the compressor 3 and be discharged from the compressor chamber 2. Further, through the high wind resistance resistance of the centrifugal fan 6 and the design of the wind tube 4, the air circulation efficiency can be improved, thereby improving the heat exchange efficiency.

[0047] Specifically, in the present embodiment, the condenser 5 is located at the front end of the air cylinder 4, the centrifugal fan 6 is located at the rear end of the air cylinder 4, the compressor 3 is located on the right side of the condenser 5, the condenser 5 is located at the left front part of the compressor chamber 2, the centrifugal fan 6 is located at the left rear part of the compressor chamber 2, and the compressor 3 is located at the right part of the compressor chamber 2, the air outlet of the centrifugal fan 6 is connected with the exhaust port 11, and correspondingly, the exhaust port 11 is located at the lower left part of the rear wall 13, and the air intake of the centrifugal fan 6 faces the condenser 5. Of course, in other embodiments, the compressor 3 can also be arranged to be located at the left part of the compressor chamber 2, the condenser 5 is located at the right front part of the compressor chamber 2, and the centrifugal fan 6 is located at the right rear part of the compressor chamber 2, that is, the compressor 3 is located on the left side of the condenser 5, and correspondingly, the exhaust port 11 is located at the lower right part of the rear wall 13.

[0048] Furthermore, the centrifugal fan 6 also includes an impeller 61, and the condensing fan assembly also includes a motor, which is drivingly connected to the impeller 61 to drive the impeller 61 to rotate and thus drive air circulation. The centrifugal fan 6 is provided with a motor bracket, and the motor is fixed to the motor bracket.

[0049] In this embodiment, the condenser 5 is a microchannel condenser, and the pipelines of the microchannel condenser 5 are arranged to extend up and down, so as to increase the contact area between the pipelines and the air.

When the refrigeration device 100 is built in the installation space, the refrigeration device 100 is located above the base 201.

[0052] The base 201 is formed with a first heat dissipation duct, and the compressor chamber 2 is connected to the external environment of the cabinet 200 through the first heat dissipation duct, so that air enters the compressor chamber 2 to dissipate heat for the compressor 3 and the condenser 5, and the front side plate of the base 201 is provided with a first heat dissipation vent 204 connected to the first heat dissipation duct. Preferably, the first heat dissipation vent 204 is in a grille shape to prevent foreign objects from entering the first heat dissipation duct and clogging it.

[0053] The cabinet 203 includes a rear plate 2031 located behind the installation space, a second heat dissipation duct is formed between the rear wall 13 of the refrigeration device 100 and the rear plate 2031 of the cabinet 203, and a second heat dissipation vent is opened on the top of the cabinet 203 to achieve air circulation between the compressor compartment 2 and the surrounding environment.

[0054] When the refrigeration device 100 is built into the installation space, the wind shield 12 abuts against the rear plate 2031, so that the second heat dissipation air duct can be isolated from the air inlet path of the compressor compartment 2 to prevent air mixing.

[0055] Specifically, the first heat dissipation air duct is connected to the first air outlet 22 , and the second heat dissipation air duct is connected to the air outlet 11 .
