[0031] The present invention will be described in detail below with reference to various 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] See also Figures 1 to 3A 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.

[0034] For ease of description, in this embodiment, the description is carried out by taking the case where the refrigeration device 100 is placed on the ground or on a base. When the door is closed, the user faces the door as a reference, and the direction from the user toward the refrigeration device 100 is defined as the direction from front to back. The direction of the refrigeration device 100 relative to the ground or the base is up, and the opposite direction is 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.

[0035] The box body 1 further defines a press chamber 2 located at a rear lower portion thereof, and the press chamber 2 defines a built-in space.

[0036] Combination Figures 4 to 8 , a compressor 21 and a condenser 22 are arranged at intervals on the left and right in the compressor chamber 2, a vent 23 extending left and right is arranged at the bottom of the compressor chamber 2, and the box body 1 also includes an air volume adjustment component 3 arranged at the vent 23, the air volume adjustment component 3 divides the vent 23 into a left vent and a right vent, and the air volume adjustment component 3 is configured to move left and right relative to the vent 23 and adjust the size of the left vent and the right vent. In this way, since the compressor 21 and the condenser 22 are arranged at intervals on the left and right, the left vent and the right vent are respectively facing the compressor 21 and the condenser 22, and the size of the left vent and the right vent can be adjusted by the air volume adjustment component 3 moving left and right relative to the vent 23, so that the size of the air volume passing through the compressor 21 and the condenser 22 can be adjusted, which is conducive to adjusting the heat dissipation of the compressor 21 and the condenser 22 according to actual needs.

[0037] In addition, a heat dissipation fan 24 is also provided in the compressor chamber 2 , and the heat dissipation fan 24 and the condenser 22 are arranged in a front-to-rear spacing, so that the heat dissipation of the compressor 21 and the condenser 22 in the compressor chamber 2 is enhanced by the heat dissipation fan 24 .

[0038] Furthermore, the press chamber 2 includes a bottom plate 25 located below the built-in space, and the box body 1 also includes a track provided on the bottom plate 25, and the air volume adjustment component 3 is configured to be matched with the track and can move left and right along the track. The setting of the track improves the adjustment convenience of the air volume adjustment component 3. Specifically, in this embodiment, the track is set as a slide rail; in other embodiments, the track can also be set as a rack, and correspondingly, the air volume adjustment component 3 is provided with a gear, and the air volume adjustment component 3 moves left and right along the track through the cooperation of the gear and the rack.

[0039] Furthermore, the vent 23 is provided at the front end of the bottom plate 25. In this embodiment, the refrigeration device 100 further comprises a bottom steel 4 located in front of the built-in space, and the vent 23 is formed between the bottom plate 25 and the bottom steel 4.

[0040] See also Figures 5 to 7 Specifically, the air volume adjustment assembly 3 includes a fixed seat 31 and a moving member 32. The fixed seat 31 is provided with a first opening 311. The moving member 32 can move relative to the fixed seat 31. The moving member 32 has an open position for opening the first opening 311 and a closed position for closing the first opening 311. The first opening 311 can be opened and closed by the moving member 32 moving relative to the fixed seat 31, so that the ventilation area through the vent 23 can be adjusted, and then the total amount of air entering or discharged from the vent 23 can be adjusted according to actual conditions.

[0041] For example, if the application environment of the refrigeration device 100 is a high-temperature area or high-temperature weather, the moving part 32 can be adjusted to the open position to improve the heat dissipation efficiency; if the application environment of the refrigeration device 100 is a low-temperature area or low-temperature weather, the moving part 32 can be adjusted to the closed position to prevent dust or insects from entering the press chamber 2 through the vent 23 and affecting the normal use of the refrigeration device 100.

[0042] The air volume adjustment assembly 3 further includes a driving mechanism 33, which is connected to the fixed seat 31. The driving mechanism 33 is provided with a gear 331, and the moving member 32 has a rack 321, and the gear 331 is meshed with the rack 321. Through the meshing connection between the driving mechanism 33 and the moving member 32, the driving mechanism 33 drives the moving member 32 to move relative to the fixed seat 31 through the gear 331, thereby realizing the opening and closing of the first opening 311.

[0043] When the driving mechanism 33 drives the moving member 32 to move to the open position, the first opening 311 is opened;

[0044] When the driving mechanism 33 drives the moving member 32 to move to the closed position, the first opening 311 is closed;

[0045] When the driving mechanism 33 drives the moving member 32 to move between the open position and the closed position, the first opening 311 is in a semi-open state.

[0046] In this way, when the moving part 32 is driven by the driving mechanism 33 to move between the open position and the closed position, the opening and closing state of the first opening 311 and the opening area of ​​the first opening 311 can be adjusted as needed, thereby improving the automation and intelligence of the refrigeration device 100. Through the meshing transmission of the gear 331 and the rack 321, the structure can also be simplified and the production difficulty can be reduced.

[0047] Preferably, the driving mechanism 33 is a motor to achieve automatic control of the air volume adjustment component 3 .

[0048] See also Figure 7 Furthermore, a through slot 322 is provided at one end of the moving part 32, and a rack 321 extends along the length direction of the moving part 32. Two racks 321 are provided, and the two racks 321 are relatively arranged on the opposite inner walls of the through slot 322.

[0049] In this embodiment, the moving member 32 and the fixing seat 31 both extend leftward and rightward, the through slot 322 is provided at the left end of the moving member 32, and the rack 321 also extends leftward and rightward. In other embodiments, the through slot 322 can also be provided at the right end of the moving member 32.

[0050] Furthermore, the moving member 32 has a second opening 323. When the moving member 32 is in the open position, the second opening 323 overlaps with the first opening 311; when the moving member 32 is in the closed position, the moving member 32 covers the first opening 311; when the moving member 32 is between the open position and the closed position, the moving member 32 covers a portion of the first opening 311. In this way, the ventilation area through the vent 23 can be adjusted by the relative movement of the moving member 32 and the fixing seat 31, thereby adjusting the total amount of air entering or discharged from the compressor chamber 2 from the vent 23.

[0051] Preferably, the second opening 323 has the same size and shape as the first opening 311 .

[0052] Furthermore, a plurality of the first openings 311 and the second openings 323 are respectively provided in a one-to-one correspondence.

[0054] Furthermore, the air volume adjustment assembly 3 further includes a stopper 34 located above the moving part 32, and the stopper 34 is fixedly connected to the fixed seat 31. The stopper 34 is provided with a plurality of third openings 341 corresponding to the first openings 311, and the third openings 341 are the same size and shape as the first openings 311. By the stopper 34 being fixedly connected to the fixed seat 31, the moving part 32 can be moved relative to the fixed seat 31, while avoiding the moving part 32 from moving away from the fixed seat 31 from above, which causes the misalignment and failure of the driving mechanism 33.

[0055] Specifically, the fixing seat 31 is connected to the bottom plate 25 and can move left and right relative to the bottom plate 25 , so that the air volume adjustment component 3 can move left and right relative to the bottom plate 25 .

[0056] The driving mechanism 33 includes a mounting portion 332 , which is fixedly connected to the fixing seat 31 , thereby preventing the driving mechanism 33 from moving relative to the fixing seat 31 , thereby causing the cooperation between the moving part 32 and the driving mechanism 33 to fail.

[0057] See also Figures 2 to 3 The box body 1 includes a rear wall 11, a top wall 12 and a pair of side walls, the pair of side walls are respectively connected to the left and right ends of the rear wall 11, the rear wall 11 is provided with an exhaust port 111, and the exhaust port 111 is connected to the compressor chamber 2, so that the compressor chamber 2 can dissipate heat to the outside from the exhaust port 111.

[0058] Specifically in this embodiment, a pair of side walls include a left side wall 13 and a right side wall 14 which are arranged opposite to each other on the left and right sides. The left side wall 13 is connected to the left end of the rear wall 11, and the right side wall 14 is connected to the right end of the rear wall 11. The top wall 12 is located above the rear wall 11, the left side wall 13, and the right side wall 14 and is connected to all three.

[0059] In this embodiment, the vent 23 serves as an air inlet.

[0060] Preferably, the heat dissipation fan 24 is arranged behind the condenser 22, and the air outlet of the heat dissipation fan 24 is connected to the exhaust port 111, so that the heat dissipation of the compressor chamber 2 can be enhanced by means of the air suction component.

[0061] See also Figure 1 to Figure 2 The refrigeration device 100 also includes a cabinet 5, and the box body 1 can be built into the cabinet 5, so that the refrigeration device 100 looks like a component of a kitchen or a living room, realizing an integrated kitchen appliance home decoration style.

[0062] The cabinet 5 includes a cabinet body 51 and a cabinet door 52, wherein the cabinet door 52 is assembled to the cabinet body 51 and can rotate relative to the cabinet body 51 to open or close the cabinet body 51. The cabinet body 51 includes a rear panel 511, a top panel 512, and a pair of side panels 513 connected to the rear panel 511, wherein the rear ends of the pair of side panels 513 are respectively connected to the left and right ends of the rear panel 511, and the top panel 512 is located above the rear panel 511 and the pair of side panels 513 and connected to the three.

[0063] A support plate is provided in the cabinet 5 , and the box body 1 can be placed above the support plate. The cabinet 5 also includes an air inlet duct 54 located below the support plate, and the air inlet duct 54 connects the vent 23 and the external space of the cabinet 5 .

[0064] Combination Figures 10 to 13 Furthermore, the refrigeration device 100 also includes an air suction component, which is located in the cabinet 5. The air suction component includes a wind tube 61 and a fan 62 arranged in the wind tube 61. One end of the wind tube 61 is connected to the exhaust port 111 through the rear space of the box body 1, and the other end of the wind tube 61 is connected to the external space of the cabinet 5.

[0065] In this way, the compressor compartment 2 can be forced to dissipate heat through the air suction component, and an air duct is formed with the help of the space between the rear wall 11 of the box body 1 and the cabinet 5. The hot air in the compressor compartment 2 is sucked out of the compressor compartment 2 and flows through the air duct and air tube 61 between the rear wall 11 of the box body 1 and the cabinet 5 in sequence, and then flows to the external space of the cabinet 5, which is beneficial to speed up the air flow rate, improve the heat dissipation efficiency of the compressor compartment 2, and save energy consumption.

[0066] See also Figures 2 to 3 Furthermore, the refrigeration device 100 further includes a back condenser 7, which is arranged at the rear side of the rear wall 11 of the box body 1, that is, the back condenser 7 is located in the air duct between the rear wall 11 of the box body 1 and the cabinet 5. On the one hand, the laying area of ​​the condenser 22 can be increased, and the refrigeration efficiency can be improved, so that the space of the compressor chamber 2 can be made smaller, which is conducive to increasing the volume of the refrigeration space and improving the volume ratio of the box body 1; on the other hand, when the fan 62 is running, the air suction component must pass through the back condenser 7 when dissipating heat to the compressor chamber 2, thereby dissipating heat to it, improving the overall heat dissipation efficiency of the box body 1 and saving energy consumption.

[0067] In this embodiment, the air suction assembly is located above the box body 1, the top plate 512 is provided with a first air outlet 5121, and the air duct 61 is connected to the rear space of the box body 1 and the first air outlet 5121. In this way, the space on the top of the cabinet 5 can be used without affecting the height of the box body 1 itself.

[0068] Of course, the air suction component can also be located on the side of the box body 1, and a second air outlet is provided on the side panel 513. The air duct 61 is connected to the rear space of the box body 1 and the second air outlet. In this way, the heat dissipation of the back condenser 7 can be achieved, and the heat dissipation efficiency of the compressor compartment 2 can be improved. The space on the top of the cabinet 5 can also be vacated to store items or for other uses.

[0069] See also Figure 2 and Fig.10 Furthermore, in this embodiment, a shelf 53 is provided in the cabinet 5, and the shelf 53 divides the space in the cabinet 5 into an installation space and a storage space, wherein the installation space is located above the shelf 53, and the storage space is located below the shelf 53. The box body 1 is located in the storage space, and the air suction assembly is located in the installation space. In this way, the air suction assembly can be supported and assembled by the shelf 53, and has a high installation strength.

[0070] Furthermore, the shelf 53 is provided with a ventilation slot 531, which connects the rear space of the box body 1 and the air duct 61, so that the shelf 53 can support the suction component while connecting the suction component with the air duct between the rear wall 11 of the box body 1 and the cabinet 5, so as to dissipate heat to the compressor compartment 2 and the back condenser 7.

[0071] Furthermore, the air duct 61 has a lower air outlet and an upper air outlet arranged in a vertically opposite manner, the lower air outlet is connected to the ventilation slot 531, the upper air outlet is connected to the first air outlet 5121, and there is a gap between the shelf 53 and the box body 1. In this way, the lower air outlet can be relatively forwardly arranged, that is, the ventilation slot 531 can be arranged above the box body 1, rather than being limited to the position directly above the air duct between the rear wall 11 of the box body 1 and the rear plate 511 of the cabinet 5. Accordingly, the position of the air duct 61 can also be relatively forwardly arranged, thereby avoiding interference between the air duct 61 and the rear plate 511 of the cabinet 5.

[0072] In this embodiment, the lower end of the air cylinder 61 is engaged with the shelf 53 .

[0073] Specifically, the outer side of the wind tube 61 near the lower end of the embodiment is provided with a convex rib 611, and the lower end of the wind tube 61 extends into the ventilation slot 531 to prevent the wind tube 61 from moving forward and backward relative to the shelf 53, and the convex rib 611 is located above the shelf 53 to limit the downward movement of the wind tube 61 relative to the shelf 53. Of course, the clamping structure of the wind tube 61 and the shelf 53 is not limited to this, and in other embodiments, the existing known clamping structure can also be used for assembly.

[0074] Preferably, the air suction assembly is detachably connected to the cabinet 5, so that the user can selectively purchase and configure it according to needs.

[0075] See also Fig.10 Specifically, in this embodiment, the air duct 61 has a first section 612 close to the box body 1, a second section 613 away from the box body 1, and a third section 614 connecting the first section 612 and the second section 613. The cross-sectional areas of the first section 612 and the second section 613, that is, the cross-sectional areas along the front-to-back direction and the left-to-right direction, are smaller than the cross-sectional area of ​​the third section 614. The fan 62 is located in the third section 614. In this way, the wind speed can be increased by utilizing the narrow tube effect in the first section 612 and the second section 613, and the third section 614 is convenient for assembling the fan 62.

[0076] In this embodiment, the first section 612 is located above the third section 614 , and the second section 613 is located below the third section 614 .

[0077] Preferably, the diameter of the upper end of the third section 614 gradually decreases toward the second section 613 , and the diameter of the lower end of the third section 614 gradually decreases toward the first section 612 .

[0078] The wind tube 61 includes a front shell and a rear shell which are arranged opposite to each other, the front shell and the rear shell enclose a ventilation duct, the fan 62 is located in the ventilation duct, and the fan 62 is fixed on the wind tube 61. Preferably, the fan 62 is fixed to the rear shell.

When the air suction component is configured, the docking terminal 15 is taken out of the embedded box 121 and docked with the outlet terminal 621 of the fan 62, so that the circuit connection of the fan 62 can be achieved, and then the fan 62 is powered.

[0081] Furthermore, the top wall 12 is provided with a storage groove, and the embedded box 121 is placed in the storage groove, which can prevent the embedded box 121 from protruding from the box body 1 and affecting the appearance, and can also prevent the volume ratio of the box body 1 from being reduced due to the provision of the embedded box 121.

[0082] Among them, the fan 62 is preferably a centrifugal fan 62 to achieve strong and efficient heat dissipation of the compressor chamber 2 and the back condenser 7.
