[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] Furthermore, it should be understood that although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are merely used to distinguish these described objects from each other. For example, a first shock-absorbing pad may be referred to as a second shock-absorbing pad, and similarly, a second shock-absorbing pad may be referred to as a first shock-absorbing pad without departing from the scope of protection of this application.

[0036] The present invention provides a refrigeration device. Figure 1 、 2 As shown in , 3 , it includes a box body with a refrigeration compartment 20 and a drawer assembly arranged in the box body. The refrigeration compartment 20 includes a receiving cavity 201 for accommodating the drawer assembly. The rear end of the receiving cavity 201 is provided with an air duct 203 and a clearance cavity 2011 along the left and right directions. The drawer assembly includes a shell 1 opening toward the front, a drawer arranged in the shell 1, and a pump module 3 arranged outside the shell 1. The pump module 3 is arranged in the clearance cavity 2011.

[0037] Among them, "front" in this article refers to the direction in which the drawer is pulled out from the shell 1, "back" is the direction in which the drawer is pushed into the shell 1 from the outside, the left and right directions are the left and right directions of the user when the user faces the opening of the shell 1, or the left and right directions are the directions perpendicular to the front and back directions in the horizontal direction, and up (or top) and down (or bottom) are customary directional words for the vertical direction.

[0038] In the refrigeration device provided by the present invention, an air duct 203 for blowing cold air into the refrigeration compartment 20 is provided at the rear end of the accommodating cavity 201, and the pump module 3 of the drawer assembly is arranged side by side with the air duct 203, that is, the space occupied by the pump module 3 originally belongs to a part of the air duct 203, and the air duct 203 serves as a transfer space for cold energy. The capacity of the air duct 203 has little effect on the transfer of cold energy. The pump module 3 only occupies part of the space of the air duct 203, and does not occupy the space of the drawer or the space of the refrigeration compartment 20, so as not to reduce the storage space in the refrigeration compartment 20. The space inside the refrigeration compartment 20 is well utilized, and the drawer assembly can also be installed as a whole, simplifying the installation steps.

[0039] In some embodiments, the refrigeration compartment 20 further includes a refrigeration cavity 202 ; the box body includes an inner liner 10 , the inner liner 10 defines the refrigeration compartment 20 , and the inner liner 10 includes a rear wall of the inner liner 10 , the air duct 203 is attached to the rear wall of the inner liner 10 and exposed to the refrigeration cavity 202 and the accommodating cavity 201 .

[0040] like Figure 1 、 2 In the embodiment, a partition 204 is provided in the refrigeration compartment 20, which is divided into a receiving cavity 201 and a refrigeration cavity 202 by the partition 204. An air duct 203 is provided behind the partition 204 and attached to the rear wall of the inner tank 10. A portion of the air duct 203 is provided in the refrigeration cavity 202, and another portion is provided in the receiving cavity 201. The air outlet and return air outlet of the air duct 203 can face the refrigeration cavity 202 and / or the receiving cavity 201 to cool the refrigeration cavity 202 and / or the receiving cavity 201. Of course, the partition 204 can also be omitted, and the top wall of the housing 1 can also serve as the partition 204 to divide the refrigeration compartment 20 into the refrigeration cavity 202 and the receiving cavity 201.

[0041] In some embodiments, the drawer assembly further includes a first shock-absorbing pad 4 disposed between the pump module 3 and the housing 1 .

[0042] like Figure 4 、 5The first shock-absorbing pad 4 is formed with a positioning groove 41 opening toward the front, and a positioning protrusion 11 that protrudes backward from the rear end of the shell 1 and matches the shape of the positioning groove 41. The positioning protrusion 11 is arranged in the positioning groove 41, so that the first shock-absorbing pad 4 and the shell 1 are positioned. The first shock-absorbing pad 4 abuts against the pump module 3 to reduce the impact of the vibration transmitted when the pump module 3 is working on the shell 1.

[0043] Furthermore, the first shock-absorbing pad 4 is also provided with a positioning notch 42 that is open toward the front and arranged horizontally, and a positioning piece 12 is also arranged horizontally at the rear end of the housing 1 corresponding to the positioning notch 42, further strengthening the positioning and fixing effect between the first shock-absorbing pad 4 and the housing 1. Of course, the arrangement direction of the positioning notch 42 and the positioning piece 12 is not necessarily horizontal, and can also be arranged at an angle to the horizontal direction. Figure 4 、 5 It is just an example. The cooperation between the horizontal positioning notch 42 and the positioning piece 12 has good stability and processability.

[0044] Preferably, the first shock-absorbing pad 4 is made of an elastic material having a certain strength and capable of processing the shape of the first shock-absorbing pad 4. The utility model utilizes the shock-absorbing properties of the elastic material itself to dampen the pump module 3 and reduce the vibration of the pump module 3 during operation.

[0045] In some embodiments, as Figures 6-9 In the figure, the pump module 3 includes a pump housing 31, a pump cover 32, a vacuum pump 33 arranged in the pump housing 31 and a second shock-absorbing pad 5. The second shock-absorbing pad 5 includes a receiving groove 511 with an upward opening, and the bottom of the vacuum pump 33 is arranged in the receiving groove 511.

[0046] A second shock-absorbing pad 5 is provided inside the pump housing 31, such as Figure 9 In the embodiment, the second shock-absorbing pad 5 is provided with a receiving groove 511 opening upward. The bottom of the vacuum pump 33 is arranged in the receiving groove 511 so that the bottom and the front, rear, left and right of the vacuum pump 33 are spaced apart from the pump housing 31. The second shock-absorbing pad 5 is utilized to reduce the impact of the vacuum pump 33 vibrating on the pump housing 31, thereby reducing the impact of the vacuum pump 33 vibrating on the drawer and the entire refrigeration equipment.

[0047] In some embodiments, a positioning block 311 protrudes upward from the bottom of the pump housing 31, and the second shock-absorbing pad 5 includes a support portion 51 formed with a receiving groove 511 and a hollow positioning foot 52 extending downward from the support portion 51, and the hollow positioning foot 52 covers the positioning block 311.

[0048] like Figure 9 、 10In the figure, two positioning blocks 311 are spaced apart along the length direction of the bottom of the pump housing 31, and two positioning legs 52 are correspondingly provided on the second shock-absorbing pad 5. The second shock-absorbing pad 5 is fixed to the pump housing 31 through the cooperation of the two positioning blocks 311 and the two positioning legs 52, preventing the vibration of the vacuum pump 33 during operation from driving the second shock-absorbing pad 5 to move inside the pump housing 31 and transmitting the vibration generated by the vacuum pump 33 to the pump housing 31. Of course, the number of positioning blocks 311 and positioning legs 52 is not limited to two, and can even be three or more. Figure 9 、 10 These are examples only.

[0049] In some embodiments, a third shock-absorbing pad 6 is further provided between the bottom of the pump housing 31 and the support portion 51 , and the third shock-absorbing pad 6 is provided with a clearance notch 61 corresponding to the positioning leg 52 , and in the vertical direction, the height of the third shock-absorbing pad 6 is not less than the height of the positioning leg 52 .

[0050] like Figure 8 To make room for the positioning legs 52, clearance notches 61 are provided at both ends of the third shock-absorbing pad 6, giving the third shock-absorbing pad 6 an I-shape. Alternatively, two through-holes can be provided at the positions corresponding to the positioning legs 52 to provide clearance. Vertically, the height of the third shock-absorbing pad 6 must be greater than or equal to the height of the positioning legs 52; otherwise, the vibration damping effect between the second shock-absorbing pad 5 and the bottom of the pump housing 31 will be lost.

[0051] In some embodiments, a fourth shock-absorbing pad 7 is further provided between the second shock-absorbing pad 5 and the pump housing 31 .

[0052] In addition to the contact between the positioning legs 52 and the pump housing 31, fourth shock-absorbing pads 7 are provided on the bottom, front, rear, left and right sides of the second shock-absorbing pad 5 to further prevent the second shock-absorbing pad 5 in direct contact with the vacuum pump 33 from transmitting the vibration of the vacuum pump 33 to the pump housing 31, and then to the drawer and even the entire refrigeration equipment.

[0053] like Figure 7 、 8 In the embodiment, a fourth shock-absorbing pad 7 may also be provided between the vacuum pump 33 and the pump housing 31 to prevent the vacuum pump 33 and the pump housing 31 from directly contacting and transmitting vibration.

[0054] In some embodiments, the second shock-absorbing pad 5 is made of elastic material, and the third shock-absorbing pad 6 and the fourth shock-absorbing pad 7 are foam.

[0055] Elastic materials have a certain strength, so they can be processed into the shape required by the second shock-absorbing pad 5 and play a certain supporting role for the vacuum pump 33. The utility model uses the shock-absorbing properties of the elastic material itself to perform preliminary shock absorption on the vacuum pump 33, reducing the vibration of the vacuum pump 33 during operation. Foam is softer and difficult to process into the required shape and use the processed structure to play the corresponding role of the structure. Foam has a better shock-absorbing effect. The foam is placed between the various structures to avoid contact between the various structures and the transmission of vibration. There is no need to specially design the shape of the foam. Figure 7 、 8 These are examples only.

[0056] In some embodiments, fifth shock-absorbing pads 8 are provided on the front, rear, left, right and bottom of the pump housing 31 and the top of the pump cover 32, so that the outer periphery of the pump module 3 abuts against the inner tank 10 and the housing through the fifth shock-absorbing pads 8.

[0057] like Figure 2 In the figure, the inner liner 10 is placed at the position where the pump module 3 is placed, which protrudes slightly backward to make room for the pump module 3. A protruding side wall is formed on the left side of the making way cavity 2011, separating the air duct 203 and the making way cavity 2011. The fifth shock-absorbing pad 8 is arranged on the front, rear, left, right and bottom of the pump housing 31 and the top of the pump cover 32 to prevent the pump housing 31 and the pump cover 32 from directly contacting the shell 1 or the inner liner 10, and the fifth shock-absorbing pad 8 is used for shock absorption.

[0058] When installing the drawer assembly into the housing, first assemble the pump module 3: Install the third shock-absorbing pad 6 at the bottom of the pump housing 31. Then, align the second shock-absorbing pad 5 with the positioning block 311 at the bottom of the pump housing 31 and place it into the pump housing 31. Insert the fourth shock-absorbing pad 7 between the second shock-absorbing pad 5 and the pump housing 31. Then, insert the vacuum pump 33 into the pump housing 31, ensuring that the bottom of the vacuum pump 33 is positioned within the second shock-absorbing pad 5. Alternatively, insert the fourth shock-absorbing pad 7 between the vacuum pump 33 and the pump housing 31 as needed. After closing the pump cover 32, secure the fifth shock-absorbing pad 8 to the front, rear, left, right, and bottom of the pump housing 31, as well as the top of the pump cover 32. This can be done by gluing or other methods, and the shape and thickness of the fifth shock-absorbing pad 8 can be adjusted based on the gap between the pump housing 31 and the housing 1 or the inner tank 10. Finally, connect the pump module 3 to the housing 1 through piping or circuitry, and push the pump module 3, the housing 1, and the drawer backward into the receiving cavity 201 to complete the installation.

[0059] In some embodiments, an oxygen extraction chamber 13 communicating with the drawer is provided on the top of the shell 1 , the vacuum pump 33 is communicated with the oxygen extraction chamber 13 , and the drawer assembly further includes an oxygen permeable membrane provided in the oxygen extraction chamber 13 .

[0060] The vacuum pump 33 is connected to the oxygen extraction chamber 13 via an oxygen extraction pipeline. The vacuum pump 33 is also provided with an oxygen exhaust pipeline, which is connected to the space outside the refrigeration compartment 20. The drawer assembly provided by the utility model is an oxygen-controlled fresh-keeping drawer. The vacuum pump 33 draws air from the drawer into the oxygen extraction chamber 13. The oxygen molecules are sucked out by the oxygen-permeable membrane in the oxygen extraction chamber 13. The oxygen is then discharged into the refrigeration compartment 20 through the oxygen exhaust pipeline, thereby reducing the oxygen content in the drawer and better preserving fruits and vegetables.

[0061] 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.

[0062] 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.
