[0027] The present application will be described in detail below with reference to the various embodiments shown in the accompanying drawings.

[0028] In the various figures of the present application, for the sake of convenience, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0029] 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.

[0030] 1 to 3 , an embedded refrigeration device 1000 provided in one embodiment of the present application includes a cabinet 100 and a refrigeration device 200. The cabinet 100 defines a storage space, and the refrigeration device 200 is built into the storage space. Thus, the refrigeration device 200 can be embedded in the cabinet 100, making it look like an integral part of the kitchen or living room, thereby realizing an integrated kitchen appliance home decoration style.

[0031] The cabinet 100 includes a cabinet body 11 and a cabinet door 12 . The cabinet body 11 defines the accommodation space. The cabinet door 12 is assembled to the cabinet body 11 and can rotate relative to the cabinet body 11 to open or close the accommodation space to operate the refrigeration device 200 built therein.

[0032] The refrigeration device 200 includes a housing 21 and a door 22. The housing 21 has a refrigeration compartment for storing and refrigerating items. The door 22 is assembled to the housing 21 and can rotate relative to the housing 21 to open or close the refrigeration compartment. The refrigeration device 200 can specifically be a refrigerator, a freezer, a wine cabinet, etc.

[0033] For ease of description, in this embodiment, the cabinet 100 is placed horizontally on the ground as an example for description. When the cabinet door 12 is closed, the user faces the cabinet door 12 as a reference, and the direction from the cabinet door 12 toward the cabinet body 11 is defined as the front-to-back direction. The direction of the cabinet 100 relative to the ground is up, and the opposite direction is down. When the user faces the cabinet door 12 from the front, the two sides of the cabinet 100 are defined as left and right, respectively.

[0034] For ease of operation, the door body 22 of the refrigeration device 200 is usually located behind the cabinet door 12 and at one end close to the cabinet door 12. In this way, after the cabinet door 12 is opened, the refrigeration device 200 can be operated, such as opening the door body 22, storing and retrieving items, and closing the door body 22.

[0035] 3 to 4 , the refrigeration device 200 includes a press chamber 23 located at its rear lower portion, the press chamber 23 includes a built-in space and a bottom plate 24 located below the built-in space, the cabinet 100 includes a support plate 13 located below the accommodating space, a first air outlet 131 is provided at the rear of the support plate 13, a second air outlet is provided at the front of the bottom plate 24, a space is provided between the support plate 13 and the bottom plate 24 and a first air duct is formed, the accommodating space has a first air duct, the first air duct is connected to the built-in space from the first air outlet 131 through the first air duct and the second air outlet in sequence.

[0036] By setting up a space between the bottom plate 24 of the compressor compartment 23 and the support plate 13 of the cabinet 100, on the one hand, it can be used as an air duct to supply air to the compressor compartment 23, which is beneficial to the heat dissipation of the compressor compartment 23, improves the service life of the compressor 232 and the condenser 233, and reduces the energy consumption of the refrigeration device 200. On the other hand, a roller 26 can be installed under the bottom plate 24 of the refrigeration device 200 to facilitate the refrigeration device 200 to be pushed into the cabinet 100, and can also support the refrigeration device 200, saving effort while avoiding the problem of opening an air outlet on the bottom plate 24 causing the roller 26 to be stuck therein and difficult to embed in the cabinet 100.

[0037] Furthermore, the press chamber 23 further includes a front chamber wall located in front of the bottom plate 24 , the lower end of the front chamber wall abuts against the support plate 13 , and the front end of the bottom plate 24 is connected to the front chamber wall.

[0038] In this embodiment, the refrigeration device 200 further includes a bottom steel structure, which includes a first plate 251, a second plate 252, and a third plate 253 connected in sequence. The first plate 251 is located above the bottom plate 24, the second plate 252 forms the front chamber wall, and the third plate 253 and the bottom plate 24 are located on the front and rear sides of the second plate 252, respectively. The third plate 253 extends away from the bottom plate 24. The first plate 251, the second plate 252, and the bottom plate 24 define the press chamber 23. In the vertical direction, the bottom plate 24 is higher than the third plate 253. In other words, the bottom plate 24 of the press chamber 23 is elevated relative to the third plate 253 of the bottom steel structure. As a result, when air in the first air duct flows from the back to the front toward the bottom steel structure, it is blocked by the second plate 252, changing its direction and favoring air flow toward the second air outlet located in the front of the bottom plate 24.

[0039] Preferably, the second air inlet is located at the junction of the bottom plate 24 and the front chamber wall, so that after the air flows into the compressor chamber 23 from the second air inlet, it can flow through the front of the built-in space as much as possible, and then pass through the entire compressor 232 and the entire condenser 233 to improve the heat exchange efficiency in the compressor chamber 23.

[0040] Preferably, the distance between the bottom plate 24 and the support plate 13 in the vertical direction is 20-30 mm, which can not only realize the air intake of the first air duct, but also ensure the top distance and bottom space between the refrigeration device 200 and the cabinet 100.

[0041] The cabinet body 11 includes a rear wall 111, and a left side wall 112 and a right side wall 113 disposed opposite each other. The rear wall 111 is located behind the storage space and connects the left side wall 112 and the right side wall 113. A windshield structure 14 is provided between the bottom plate 24 and the rear wall 111. Providing the windshield structure 14 between the bottom plate 24 and the rear wall 111 prevents air from entering the first air duct from the first air outlet 131, flowing upward from between the bottom plate 24 and the rear wall 111, then passing through the back panel of the refrigeration unit 200 to the top thereof, and then flowing out of the storage space of the cabinet 100, resulting in the air not passing through the compressor compartment 23 and being unable to dissipate heat from the compressor compartment 23.

[0042] The windshield structure 14 can be set on the refrigeration equipment, specifically on the bottom plate 24. When the refrigeration equipment is built into the cabinet 100, the windshield structure 14 abuts against the rear wall 111 of the cabinet 100, thereby preventing the wind from entering the first air duct from the first air outlet 131 and flowing upward from between the bottom plate 24 and the rear wall 111; in other embodiments, the windshield structure 14 can also be set on the cabinet 100, specifically on the rear wall 111 corresponding to the bottom plate 24. When the refrigeration equipment is built into the cabinet 100, the windshield structure 14 abuts against the bottom plate 24, thereby preventing the wind from entering the first air duct from the first air outlet 131 and flowing upward from between the bottom plate 24 and the rear wall 111.

[0043] Preferably, the wind shielding structure 14 is a sponge strip, which can not only shield the wind to prevent the wind from flowing upward from between the bottom plate 24 and the rear wall 111 without passing through the press chamber 23, but also has the effect of reducing shock and noise.

[0044] Preferably, the windshield structure 14 extends from the left end of the bottom plate 24 to the right end of the bottom plate 24. Furthermore, the windshield structure 14 connects the left side wall 112 and the right side wall 113 of the cabinet body 11, thereby achieving maximum windproof effect and improving the heat exchange efficiency of the compressor chamber 23.

[0045] More preferably, the windshield structure 14 is located behind the refrigeration device 200 and surrounds the press chamber 23 in a ring shape. In this way, the rear wall of the cabinet 100 can be used as the rear wall of the press chamber 23, and the rear wall of the press chamber 23 can be eliminated, which can save materials.

[0046] 4 to 6 , the compressor compartment 23 further includes a fan 231 , a compressor 232 and a condenser 233 arranged in the built-in space. The compressor 232 compresses the refrigerant into a high-temperature, high-pressure gas, which then flows into the condenser 233 for heat dissipation. The refrigerant is converted into a liquid at room temperature and high pressure, and further converted into a low-temperature, low-pressure gas when flowing through the capillary tube, thereby performing heat exchange with the storage compartment of the refrigeration device 200 to cool the storage compartment. The high-temperature refrigerant then flows back to the compressor 232 .

[0047] In this embodiment, the condenser 233 is a microchannel condenser to increase the volumetric efficiency of the refrigeration device 200. The fan 231 and the condenser 233 are arranged in a front-to-back relationship. The compressor 232 is spaced apart from the condenser 233. The fan 231 and the condenser 233 can be integrally formed or arranged separately.

[0048] The air outlet 2311 of the fan 231 extends from bottom to top toward the rear space of the refrigeration device 200 to achieve the above-mentioned air circulation.

[0049] The wind shielding structure 14 is located below the air outlet 2311 to prevent the hot air discharged from the compressor chamber 23 from flowing back into the compressor chamber 23 .

[0050] The top of the cabinet 100 is provided with a top air vent so that air can flow from the accommodating space of the cabinet 100 to the external environment, thereby achieving effective heat dissipation of the compressor compartment 23 .

[0051] Preferably, the air outlet 2311 is provided at the top rear end of the cabinet 100 to shorten the heat dissipation path and discharge the air in the second air path out of the cabinet 100 as quickly as possible.

[0052] Specifically in this embodiment, a pair of second air outlets are provided, and a pair of second air outlets are distributed at left and right intervals on the front of the bottom plate 24, so that the air sent into the compressor chamber 23 by the first air duct is divided into two paths, which flow into the compressor chamber 23 from a pair of second air outlets respectively. Since the compressor 232 and the condenser 233 are arranged at left and right intervals, the air flowing into the compressor chamber 23 from one of the second air outlets flows through the compressor 232, and the air flowing into the compressor chamber 23 from the other second air outlet flows through the condenser 233. Under the action of the fan 231, the compressor 232 and the condenser 233 are cooled respectively, thereby improving the heat dissipation efficiency.

[0053] Specifically, in order to improve the heat dissipation efficiency, one of the second air outlets is set close to the compressor 232, and the other second air outlet is set close to the condenser 233, which is conducive to the wind in the first air duct reaching the compressor 232 or the condenser 233 as soon as possible after passing through the second air outlet, shortening the wind path and improving the heat dissipation efficiency.

[0054] Furthermore, the cabinet 100 further includes a base 15 , wherein a second air duct is formed between the base 15 and the support plate 13 , and the second air duct is connected to the first air duct and the external environment.

[0055] The base 15 is provided with a third air outlet 151 , and the third air outlet 151 connects the external environment with the second air duct.

[0056] Furthermore, the base 15 is provided with a grille, which is located below the support plate 13 of the cabinet 100, that is, the grille forms the third air outlet 151. The wind enters the first air duct from the grille outside the cabinet 100, and then enters the compressor compartment 23 under the action of the fan 231 to dissipate heat for the compressor 232 and the condenser 233.

[0057] Furthermore, the storage space also has a second air path, which connects to the external environment from the built-in space through the space behind the refrigeration device 200 and the space above the refrigeration device 200. In this way, the embedded refrigeration device 1000 implements a heat dissipation path in which air enters from the bottom of the cabinet 100, exchanges heat in the compressor compartment 23, flows through the space behind the refrigeration device 200 to the top space, and then exits from the top of the cabinet 100. This fully utilizes the space in the cabinet 100 for auxiliary heat dissipation and provides excellent sound insulation.

[0058] Referring to Figures 7 and 8 , in some embodiments, the embedded refrigeration device 1000 further includes at least one refrigerator / freezer 300 arranged side by side with the refrigeration device 200. Each refrigerator / freezer 300 has an air outlet 2311 and a windshield 31 located above the air outlet 2311 on its back panel. The windshield 31 of each refrigerator / freezer 300 directs the air flowing out of its air outlet 2311 to the space behind the refrigeration device 200. This allows the refrigeration device 200 to share a heat dissipation channel with other refrigerator / freezers 300, allowing hot air flowing out of the compressor compartment 23 to be discharged out of the cabinet 100, thereby allowing the refrigeration devices 200 to be arranged appropriately according to the application scenario. The refrigerator / freezer 300 can be the same as the refrigeration device 200, such as both being refrigerators. Of course, the refrigerator / freezer 300 can also be different from the refrigeration device 200, such as the refrigeration device 200 being a refrigerator and the refrigerator / freezer 300 being a wine cabinet. The specific arrangement can be determined based on the actual application scenario.

[0059] This embodiment is suitable for the renovation and installation of a large-space cabinet 100. If the cabinet 100 on the side of the refrigerator-freezer 300 is inconvenient for exhaust, this solution can be adopted.

[0060] In this embodiment, the wind shield 31 extends from the refrigeration and freezing device 300 in which it is located to the back panel of the refrigeration device 200; in other embodiments, if the refrigeration and freezing device 300 is not adjacent to the refrigeration device 200, the wind shield 31 can be set to extend from the refrigeration and freezing device 300 in which it is located to the back panel of the refrigeration device 200, or the wind shield 31 can be set to extend from the refrigeration and freezing device 300 in which it is located to connect with the wind shield strip of the refrigeration and freezing device 300 adjacent to it.

[0061] In this way, the hot air discharged from the compressor chamber 23 of the refrigeration and freezing device 300 can be guided to the rear space of the refrigeration device 200, so that the hot air flowing out of the compressor chamber 23 can be discharged through the heat dissipation channel of the refrigeration device 200.

[0062] Compared with the prior art, the embedded refrigeration device 1000 provided by the present application has the following beneficial effects: the present application provides a space between the bottom plate 24 of the press chamber 23 and the support plate 13 of the cabinet 100. On the one hand, it can be used as an air duct to supply air into the press chamber 23, thereby facilitating the heat dissipation of the press chamber 23, improving the service life of the compressor 232 and the condenser 233, and reducing the energy consumption of the refrigeration device 200. On the other hand, a roller 26 can be installed under the bottom plate 24 of the refrigeration device 200 to facilitate the refrigeration device 200 to be pushed into the cabinet 100, and it can also support the refrigeration device 200, saving effort while avoiding the problem of opening an air outlet on the bottom plate 24 causing the roller 26 to be stuck therein and difficult to embed in the cabinet 100.

[0063] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0064] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of this application. They are not intended to limit the scope of protection of this application. Any equivalent implementation methods or changes that do not deviate from the technical spirit of this application should be included in the scope of protection of this application.
