Embodiment 1

[0036] In this embodiment, the structural design and working principle of the adjustable air pressure balance valve are described in detail by taking the application of the adjustable air pressure balance valve in the refrigerator as an example.

[0037] See attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 , attached Figure 5 , attached Figure 6 , attached Figure 7 And attached Figure 8 The refrigerating device 100 of this embodiment includes a cabinet body 101 and a door body 102, the door body 102 is hinged to the cabinet body 101, and when the door body 102 is closed, the cabinet body 101 and the door body 102 form a closed storage space 113 for Frozen or refrigerated items.

[0038] In order to make the refrigerator 100 keep the air pressure in the storage space 113 in balance with the outside atmospheric pressure even when the door 102 is closed, an adjustable air pressure balance valve 103 is provided on the refrigerator 100 in t...

Embodiment 2

[0043] See attached Figure 9 , attached Figure 10 , attached Figure 11 And attached Figure 12 In this embodiment, on the basis of Embodiment 1, the first gas passage 104 used to communicate with the outside air is in the shape of a cuboid. At this time, the air inlet is also in the shape of a rectangle; The gas channel 104 cooperates, and the sealing plug 108 is also in the shape of a cuboid. In order to further improve the performance of the pressure balance valve 103, fully protect the sealing plug 108, and facilitate the opening or closing of the sealing plug 108; preferably, the first gas passage 104 extends to the inside of the gas connection passage 106, that is, the first gas passage 104 The A gas outlet 116 is located inside the gas connection channel 106 , the sealing plug 108 abuts against the first gas outlet 116 , and the sealing plug 108 is used to open or close the first gas outlet 116 . The first gas passage 104 extends to the inside of the gas connectio...

Abstract

The invention provides an adjustable air pressure balance valve and a refrigeration device using the air pressure balance valve. The adjustable air pressure balance valve comprises a first gas channel, a second gas channel and a gas connecting channel, the gas connecting channel is provided with a gas inlet and a gas outlet, the gas inlet is connected with the first gas channel, and the gas outlet is connected with the second gas channel; and an adjusting valve composed of a sealing plug, an elastic element, an adjusting rod and a positioning part is arranged in the gas connecting channel, the sealing plug is used for opening or closing the gas inlet, the elastic element has initial compression amount, one end of the elastic element is connected with the sealing plug, the other end of the elastic element is connected with the adjusting rod, the adjusting rod can do reciprocating rectilinear motion, and the positioning part is used for positioning the adjusting rod. The sealing plug is arranged on the air inlet, so that external air cannot enter the refrigeration device; when the internal and external pressure difference is increased, the air inlet is opened, external air enters the refrigeration device, and internal and external air pressure balance is achieved; and the adjustable air pressure balance valve also can adjust the critical pressure difference when the sealing plug is opened and is convenient and practical.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an adjustable air pressure balance valve and a refrigeration device using the air pressure balance valve. Background technique [0002] In real life, when users use refrigerators, freezers and other refrigeration devices, since the temperature inside the freezer is low and the temperature outside the refrigeration equipment is high, the temperature difference between the outside and inside of the refrigeration equipment is large. Create negative pressure. Moreover, the functions of refrigerating devices such as existing refrigerators and freezers are more and more diversified, and the temperature of the inner freezer box can be set according to actual needs, especially when freezing different foods and in different seasons and different regions. At the same time, the temperature difference brought by the freezer boxes of different temperatures is also...
