[0022] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] It should be understood that the terms used herein, such as "upper," "lower," "inner," and "front," etc., indicating spatial relative positions, are used for ease of explanation to describe the relationship of one component or feature relative to another component or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation other than the orientation shown in the drawings.

[0024] See also Figures 1 to 4 As shown, the present invention provides a refrigeration device 100, comprising a housing 1, wherein a refrigeration compartment is provided within the housing 1. It is understood that the refrigeration compartment may be a refrigerator compartment, a freezer compartment, a variable temperature compartment, or the like. Specifically, the refrigeration compartment is provided with an integrated refrigeration system, comprising an evaporator cover plate 2 connected to the housing 1. The evaporator cover plate 2 encloses an evaporation chamber, within which an evaporator, a fan 3, and an air duct assembly 4 are mounted. The evaporator is used to provide cooling to the refrigeration compartment, and the air duct assembly 4 connects the evaporation chamber and the refrigeration compartment. Since the evaporator is located within the refrigeration compartment, the air duct formed by the air duct assembly 4 is shorter, thereby reducing cooling loss during transmission and improving cooling utilization.

[0025] It is understandable that the refrigeration equipment 100 can be an existing refrigeration device such as a refrigerator or freezer. A compressor, a condenser, and a throttle valve are provided inside the refrigeration equipment 100. The compressor, condenser, throttle valve and the evaporator in the integrated refrigeration system are connected in sequence to form a refrigeration circuit, so that the evaporator continuously provides cooling for the refrigerated compartment.

[0026] In one embodiment of the present invention, the air duct assembly 4 is formed by the evaporator cover plate 2, and the fan 3 is connected to the evaporator cover plate 2. Since the air duct assembly 4 and the evaporator cover plate 2 are integrally provided, the air duct assembly 3 is integrally formed and has no seams within the air duct assembly 3. This improves the sealing performance of the air duct assembly 3, reduces cooling loss during transmission, increases the cooling efficiency of the evaporator, and achieves better cooling effect in the refrigerated compartment. In addition, the air duct assembly 4 and the evaporator cover plate 2 are integrally provided, avoiding the problem of frosting caused by poor sealing between the air duct assembly 4 and the evaporator cover plate 2.

[0027] Furthermore, the evaporator cover 2 may be provided with a mounting slot for the fan 3, into which the fan 3 is removably connected. It is understood that the manner in which the fan 3 is connected to the evaporator cover 2 is not limited thereto. The fan 3 includes an air inlet and an air outlet. The air inlet of the fan 3 is positioned near the evaporator, directing the cooling energy from the evaporator toward the air outlet. After the fan 3 is installed in the mounting slot, the air outlet of the fan 3 communicates with the air duct assembly 4, thereby transferring the cooling energy from the evaporator to the interior of the refrigeration compartment.

[0028] In another embodiment of the present invention, see Figure 2 As shown, the evaporator cover 2 and the duct assembly 4 are separately configured. Specifically, the duct assembly 4 includes an air inlet side 47 and an air outlet side 48. The duct assembly 4 forms an air duct for transferring cooling energy. The side of the duct close to the fan 3 is the air inlet side 47, and the side of the duct away from the fan 3 is the air outlet side 48. Cooling energy flowing out of the fan outlet enters the duct through the air inlet side 47 of the duct assembly 4. The cooling energy is then guided through the duct and enters the refrigerated compartment through the air outlet side 48 of the duct assembly 4. The cooperation between the fan 3 and the duct assembly 4 rapidly transfers cooling energy from the evaporator to the refrigerated compartment.

[0029] Furthermore, the evaporator cover 2 is provided with an opening 21 for the air duct assembly 4 to pass through, and the air duct assembly 4 is provided with a sealing surface 41 abutting the opening 21, and a seal located between the opening 21 and the sealing surface 41. After the air duct assembly 4 and the evaporator cover 2 are installed, the opening 21 presses the seal and the sealing surface 41, thereby ensuring the sealing of the evaporation chamber and the air duct assembly 4 and avoiding frost.

[0030] Furthermore, the duct assembly 4 has an air inlet side 47 located within the evaporation chamber and an air outlet side 48 located outside the evaporator chamber. The air inlet side 47 is connected to the air outlet of the fan 3, and the air outlet side 48 is connected to the refrigeration compartment. The duct assembly 4 includes a first duct cover plate 42 and a second duct cover plate 43 located below the first duct cover plate 42. The first duct cover plate 42 and the second duct cover plate 43 are fastened together to form an air duct cavity. By designing the duct assembly 4 as a split upper and lower structure, the processing of the duct assembly 4 is facilitated. Of course, it is understood that the split design of the duct assembly 4 is not limited to the upper and lower directions, and can also be a left-right split structure or a split structure in other directions.

[0031] Furthermore, the first air duct cover plate 42 is provided with a first mounting surface near the air inlet side 47, and the second air duct cover plate 43 is provided with a second mounting surface opposite to the first mounting surface near the air inlet side 47, and the first mounting surface and the second mounting surface enclose a mounting cavity 44 connected to the fan 3. Figure 4 As shown, when installing the fan 3, the fan 3 is inserted into the installation cavity 44, which realizes the rapid alignment and rapid installation of the fan 3 and the air duct assembly 4, and also ensures the reliability of the connection between the air outlet of the fan 3 and the air inlet side 47 of the air duct assembly 4. Furthermore, along the installation direction of the fan 3, the first air duct cover plate 42 and the second air duct cover plate 43 are provided with limiting ribs to ensure the position of the fan 3 in the installation cavity 44, so that the fan 3 can be quickly installed in place. It is understandable that after the fan 3 is installed in the installation cavity 44, the fan 3 can be fixed to the first installation surface by means of a threaded connection, thereby realizing a detachable connection between the fan 3 and the air duct assembly 4.

[0032] Further, see Figure 3 As shown, the first air duct cover plate 42 includes two first side walls 421 arranged opposite to each other in the horizontal direction, and a first top wall 422 connected to the two first side walls 421. The second air duct cover plate 43 includes two second side walls 431 arranged opposite to each other in the horizontal direction, and a first bottom wall 432 connected to the two second side walls 431. The first top wall 422 and the first bottom wall 432 are arranged opposite to each other. One of the first side wall 421 and the second side wall 431 is provided with a buckle 423, and the other is provided with a slot 433 that interfaces with the buckle 423. The connection between the buckle 423 and the slot 433 realizes the buckling connection between the first air duct cover plate 42 and the second air duct cover plate 43.

[0033] Specifically, the horizontal width of the first top wall 422 is smaller than the horizontal width of the first bottom wall 432. Multiple latches 423 are protruding from the outer surface of each first side wall 421, spaced apart along the outer surface of the first side wall 421. A corresponding plurality of slots 433 are provided on the inner end surface of each second side wall 431. It is understood that the slots 433 may be through-slots extending through the second side wall 431. When the first and second air duct cover plates 42 and 43 are engaged, the first top wall 422 is positioned directly above the first bottom wall 432, and the two first side walls 421 are positioned within the space enclosed by the two second side walls 431 and the first bottom wall 432. Each latch 423 engages with a corresponding slot 433, securely connecting the first and second air duct cover plates 42 and 43, and allowing the first and second air duct cover plates 42 and 43 to engage to form an air duct.

[0034] Furthermore, two stop walls 434 arranged horizontally opposite to each other are protruded from the same side of the first bottom wall 432 and the second side wall 431. It can be understood that each of the stop walls 434 is arranged on the inner side of the corresponding second side wall 431, and the stop wall 434 and the second side wall 431 are arranged in a conformal manner so that a fixed distance is maintained between the stop wall 434 and the corresponding second side wall 431. The stop wall 434 and the corresponding second side wall 431 form a stop groove. After the first air duct cover plate 42 and the second air duct cover plate 43 are buckled together, each of the first side walls 421 is inserted into the corresponding stop groove, thereby improving the sealing of the air duct formed by the first air duct cover plate 42 and the second air duct cover plate 43, and reducing the loss of cold air in the air duct during transmission.

[0035] Furthermore, the height of the stop wall 434 is lower than the height of the second side wall 431, thereby ensuring that after the first side wall 421 is inserted into the stop groove, the buckle 423 on the outer surface of the first side wall 421 can be smoothly inserted into the slot 433 of the second side wall 431, thereby realizing a detachable connection between the first air duct cover 42 and the second air duct cover 43.

[0036] Furthermore, the fan 3 and the evaporator in the evaporation chamber can be arranged horizontally or vertically. In a specific embodiment of the present invention, the evaporator cover 2 is connected to the top of the box body 1, and the fan 3 in the evaporation chamber is located on the upper side of the evaporator, and the air inlet of the fan 3 is close to the evaporator. The air duct assembly 4 is connected to the top of the box body 1. Specifically, the box body 1 includes an inner liner 11, and the refrigeration equipment 100 also includes a bracket 5 connected to the top of the inner liner 11. It can be understood that the bracket 5 is located on the outside of the top of the inner liner 11, and the air duct assembly 4 is located on the inside of the top of the inner liner 11, that is, the inner liner 11 is located between the bracket 5 and the air duct assembly 4. A through groove is provided on the inner liner 11, and the air duct assembly 4 is connected to the bracket 5 via the through groove, so that the fan 3 and the air duct assembly 4 are fixedly connected to the bracket 5 at the same time. It is understandable that the way the fan 3 and the air duct assembly 4 are fixed to the upper side of the evaporator is not limited to this, but connecting the fan 3 and the air duct assembly 4 to the box body 1 by means of the bracket 5 can increase the strength of the connection between the air duct assembly 4 and the box body 1.

[0037] Furthermore, the air duct assembly 4 further includes a connecting portion 45 protruding from the outer side of the second side wall 431 toward the hanger 5, a connecting hole 451 provided on a side of the connecting portion 45 away from the second side wall 431, and a screw passing through the connecting hole 451 and connected to the hanger 5. The screw passing through the connecting hole 451 of the connecting portion 45 connects the air duct assembly 4 and the hanger 5, thereby facilitating quick installation and removal of the air duct assembly 4. It is understood that the connection method between the air duct assembly 4 and the hanger 5 is not limited to this. The air duct assembly 4 and the hanger 5 can be connected by a snap connection, or a combination of a threaded connection and a snap connection.

[0038] Furthermore, the duct assembly 4 further includes a support portion 46 protruding from the first top wall 422. The side of the support portion 46 away from the first top wall 422 includes a support surface 461 that abuts the inner liner 11. Specifically, the support surface 461 is located in the middle of the duct assembly 4, and the connecting portion 45 and the screws are located on both sides of the duct assembly 4. After the duct assembly 4 and the bracket 5 are connected, the support surface 461 is used to withstand the tightening force of the screws. On the other hand, the abutment between the support surface 461 and the inner liner 11 can prevent the duct assembly 4 from being suspended in the air and generating loud noise when the fan 3 is in operation.

[0039] Furthermore, the bracket 5 is recessed with a relief groove 51, and the fan 3 is tilted within the relief groove 51. This allows the evaporation chamber to only accommodate the height of the evaporator, thereby reducing the height of the evaporation cover and increasing the space utilization within the refrigeration device 100. Furthermore, the fan 3 is tilted within the relief groove 51 to guide the defrost water from the fan 3 toward the lower side of the fan 3, thereby facilitating centralized collection and processing of the defrost water. It is understood that the accommodation space formed within the relief groove 51, and the first and second duct cover plates 42, 43 of the duct assembly 4 forming the mounting cavity 44 for the fan 3, are disposed within the accommodation space of the relief groove 51, thereby positioning the fan 3 within the relief groove 51. In other embodiments of the present invention, the relief groove 51 can also be tilted, with the duct assembly 4 snugly mounted within the relief groove 51, and the fan 3 then installed in the mounting cavity 44, thereby arranging the fan 3 in an inclined position.

[0040] Furthermore, the refrigeration compartment comprises an ice-making compartment, in which an ice-maker 6 is installed. The ice-maker 6 and the refrigeration system can both be mounted on the top of the ice-making compartment, and the ice-maker 6 and the refrigeration system can be arranged on either side. The air outlet 48 is located on the side of the ice-maker 6 near the back of the inner liner 11, allowing the cold air within the air duct assembly 4 to be quickly transferred to the ice-maker 6. In the present invention, the ice-maker 6 includes an ice tray for producing ice cubes, and an air inlet 61 connected to the air outlet 48 of the air duct assembly 4. The air inlet 61 is located on the side of the ice-maker 6 near the back of the inner liner 11. Preferably, the air inlet 61 is located near the open end of the ice tray, allowing the water in the ice tray to quickly absorb the cold air within the air duct, thereby accelerating the ice-making process of the ice-maker 6.

[0041] Furthermore, the avoidance groove 51 on the hanger 5 is located near the back of the inner liner 11, the fan 3 is located in the avoidance groove 51 of the hanger 5, the air inlet side 47 of the air duct assembly 4 is located near the back of the inner liner 11, and the air outlet side 48 of the air duct assembly 4 is also close to the back of the inner liner 11, thereby reducing the length of the air duct assembly 4 and preventing cooling loss. Specifically, the air duct assembly 4 is arranged from high to low from the air inlet side 47 to the air outlet side 48, and the width of the air duct assembly 4 gradually decreases from the air inlet side 47 to the air outlet side 48. This ensures that the air inlet side 47 can be connected to the air outlet of the fan 3, while also reducing the volume occupied by the air duct assembly 4 in the refrigeration room.

[0042] 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.

[0043] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
