Description

Technical Field

[0001] The invention relates to the field of heat preservation equipment, and in particular to an inflatable storable refrigeration device. Background Art

[0002] In the prior art, the heat-insulating shell of a refrigerator is usually made of a hard material, such as polyurethane, a vacuum insulation board, etc., and the outer shape, volume and internal space are mostly unchangeable. Therefore, when it is not needed, it occupies a large space and is not easy to store.

[0003] In order to meet people's demand for refrigerators that are storable and portable, inflatable refrigeration devices have gradually appeared on the market. For example, the Chinese patent with publication number CN117537535A discloses a variable-volume refrigerator, including a refrigerator, a refrigeration system and an inflating system; a gas storage tank for storing argon gas is installed on one side of the second compressor; through the refrigerator and the inflating system, the refrigerator, the first box body and the second box body that can be raised and lowered are composed of the refrigerator, the argon gas in the gas storage tank is filled into the airbag through the pipeline as the solenoid valve is opened, and the airbag can push up the second box body to make the second box body rise, and as the second box body rises, the inner cavity volume of the first box body and the second box body increases; when the solenoid valve is closed, the argon gas in the airbag is recompressed into the gas storage tank through the pipeline and the second compressor, and the second box body can be lowered.

[0004] The above refrigerator has the following problems: 1. The argon gas in the airbag returns to the gas storage tank, and the airbag gradually collapses. Under the action of gravity, the second box moves downward into the first box, but the first box and the second box are not foldable, resulting in the refrigerator still occupying a large space after deflation. 2. The airbag does not have a heat insulation effect, resulting in poor heat preservation effect of the above refrigerator.

[0005] In view of this, the present invention proposes an inflatable refrigerated device to solve the above problems. Summary of the invention

[0029] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0030] Reference Figure 1-5 , an embodiment of an inflatable refrigerated storage device of the present invention is proposed:

[0031] An inflatable refrigeration device includes an inflatable side wall 1. The inflatable side wall 1 encloses a refrigeration cavity 2, the top opening of the inflatable side wall 1 is provided with an openable top cover 3, and the bottom opening of the inflatable side wall 1 is connected to a box 4. The inflatable side wall 1 includes two layers of thermal insulation composite film material 12, and the inflatable cavity 11 is between the two layers of thermal insulation composite film material 12. The box 4 is provided with an inflating and exhausting module 5 for inflating or exhausting the inflatable cavity 11, and a refrigeration module for refrigerating the refrigeration cavity 2.

[0032] like Figure 4 As shown, the top of the inflatable side wall 1 is a shaped top surface 13, and the bottom of the inflatable side wall 1 is a shaped bottom surface 14. The two layers of the thermal insulation composite membrane material 12 are connected by the shaped top surface 13 and the shaped bottom surface 14 to form an inflatable cavity 11.

[0033] The shaped bottom surface 14 is fixedly connected to the top of the box body 4. Figure 1 As shown, the inflation and exhaust module 5 includes an inflation pipeline 51, an inflation pump 52 installed in the box body 4, and a pressure gauge for detecting the pressure in the inflation chamber 11. The shaped bottom surface 14 is provided with a vent hole 141, one end of the inflation pipeline 51 is connected to the vent hole 141, and the other end of the inflation pipeline 51 is connected to the inflation port of the inflation pump 52. The inflation pump 52 inputs air into the inflation chamber 11. When the pressure gauge detects that the pressure in the inflation chamber 11 reaches the standard pressure, the inflation pump 52 stops working. The inflation pipeline 51 is provided with an exhaust valve 53.

[0034] The refrigeration module is a compressor refrigeration module 6, which includes a refrigeration pipeline 61, a compressor 62 installed in a box body 4, a condenser, an expansion valve, and a conduction plate 63 installed on the top of the box body 4. An evaporator is provided in the conduction plate 63. The refrigeration pipeline 61 is used to circulate the refrigerant to the compressor 62, the condenser, the expansion valve, and the evaporator in sequence.

[0035] The inner wall of the box body 4 is provided with a heat sink 64 adjacent to the compressor 62 to assist the compressor 62 in dissipating heat when working.

[0036] Since frost is generated when the refrigeration module is working, a through hole is provided at the bottom of the box body 4 to discharge excess water generated by defrosting.

[0037] In other embodiments, the refrigeration module may be a semiconductor refrigeration plate, which is mounted on the top of the box 4 and is located in the air-filled cavity 11 .

[0038] The box body 4 is provided with a battery 41, a control module for controlling the operation of the gas charging and exhausting module 5 and the refrigeration module, and a temperature sensor for detecting the temperature of the refrigeration cavity 2. The battery 41 is used to provide power to the refrigeration module and the gas charging and exhausting module 5. The control module includes an operation control panel 42. The operation control panel 42 is provided with a temperature display screen 421 and a refrigeration temperature control button 422. The temperature display screen 421 displays the temperature of the refrigeration cavity 2, and the refrigeration temperature control button 422 adjusts the temperature of the refrigeration cavity 2 by controlling the operation of the refrigeration module.

[0039] The top cover 3 includes a frame body 31 fixedly connected to the shaped top surface 13 , and the frame body 31 is provided with a refrigerator door 32 that can be opened and closed relative to the frame body 31 .

[0040] The shaped top surface 13 and the shaped bottom surface 14 are both silicone planes, and the shaped top surface 13 and the top cover 3, and the shaped bottom surface 14 and the top of the box body 4 are connected tightly and firmly by hot melting or ultrasonic welding, effectively preventing the cold air in the refrigerated cavity 2 from leaking and improving the refrigeration effect. The two layers of thermal insulation composite film material 12 and the silicone plane are also welded by hot melting or ultrasonic welding, so that the airtightness of the inflatable cavity 11 is good, and the air leakage of the inflatable side wall 1 is prevented.

[0041] like Figure 1 As shown, the thermal insulation composite membrane material 12 includes a wear-resistant surface layer 121, an adhesive layer 122, a thermal insulation support middle layer 123, an adhesive layer 122, and a thermal insulation metal inner layer 124 which are stacked in sequence.

[0042] Specifically, the wear-resistant surface layer 121 is a PVC film, which can make the inflatable side wall 1 have good flexibility, wear resistance and waterproofness. The heat-insulating support middle layer 123 is a low-density foam layer, which not only has good heat-insulating performance, but also can provide necessary structural support for the inflatable side wall 1, ensuring that the inflatable side wall 1 can maintain a stable shape after inflation.

[0043] The heat-insulating metal inner layer 124 is a thin aluminum layer, which has good reflective properties and a low thermal conductivity, and can reflect the heat outside the inflatable side wall 1, further improving the heat-insulating performance of the inflatable side wall 1.

[0044] The thin aluminum layer also increases the mechanical strength of the inflatable side wall 1. Compared with other metals capable of heat insulation, the price of aluminum is relatively low, and the density of aluminum is low, so it will not significantly increase the weight of the inflatable side wall.

[0045] In this embodiment, the thickness of the PVC film is 0.3 mm, the thickness of the low-density foam layer is 2 mm, and the thickness of the thin aluminum layer is 0.08 mm.

[0046] The cross-sections of the inner and outer sides of the inflatable side wall 1 along the vertical direction are wavy, and the inner and outer sides are symmetrical along the vertical direction, so that the inflatable side wall 1 forms wavy folds, which is convenient for folding and storing the inflatable side wall.

[0047] The working process of the refrigeration device of the present invention is as follows: when food needs to be refrigerated, the air pump 52 is started, and the air pump 52 delivers air to the air-filled cavity 11, so that the air-filled side wall stands up to form the refrigeration cavity 2. Then the refrigeration module is started, so that the temperature of the refrigeration cavity 2 is reduced. When the refrigeration device needs to be folded and stored, the exhaust valve 53 is opened to exhaust the air in the air-filled cavity 11, and then the air-filled side wall is folded in the vertical direction to reduce the space occupied by the refrigeration device.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
