Embodiment 1

[0026] In the air pressure balance device provided in this embodiment, the core tube 32 and the communication tube 31 can be integrally formed, but the installation of the elastic tube 34 is very inconvenient. Therefore, the core tube 32 and the communication tube 31 are detachably connected. Such as figure 2 As shown, the core tube 32 can be threadedly connected to the communication tube 31 , or the core tube 32 and the communication tube 31 can be clamped by a buckle structure.

[0027] Since the core tube 32 also needs to be sleeved with an elastic tube 34 to block the lateral air holes 33, the core tube 32 is arranged in the connecting tube 31 for ease of implementation, such as figure 2 As shown, when the core tube is arranged in the connecting tube 31, the outer wall of the core tube 32 can be screwed to the inner wall of the connecting tube 31. In this way, firstly, the elastic tube 34 is placed on the core tube 32 and sealed. side air hole 33, and then put the core ...

Embodiment 2

[0036] The difference between the air pressure balance device provided in this embodiment and Embodiment 1 is: image 3 As shown, an outer flange 321 is provided at the mouth of the core pipe 32 for communicating with the outside of the storage room 1, and an inner flange 313 is provided at the mouth of the inner end of the communication pipe 31, and the core pipe 32 is connected to the outer surface of the communication pipe 31. At the mouth of the pipe, and the outer flange 321 abuts against the outer end surface of the connecting pipe 31 . refer to image 3 and Figure 4 When installing the air pressure balance device 3, the connecting pipe 31 is first installed into the installation hole of the air pressure balance device 3 from the inside of the storage room 1, and the inner flange 313 is against the inner wall of the storage room 1, and then the core pipe is inserted from the outside of the storage room 1. 32 is connected to the communication pipe 31 , and the outer fl...

Abstract

The invention discloses an air pressure balancing device and a refrigeration device, relates to the technical field of refrigeration, and aims to solve the problems that in the prior art, the interior of the refrigeration device frosts and the energy consumption is increased due to air pressure balancing. The air pressure balancing device is used for balancing the air pressure inside and outside a storage chamber of the refrigeration device, and comprises a communication tube used for communicating with the interior and exterior of the storage chamber, and a core tube arranged inside the communication tube, wherein one end of the core tube is used for communicating with the exterior of the storage chamber, and the other end of the core tube is closed; lateral air holes are formed in the side wall of the core tube; an elastic tube is arranged on the side wall of the core tube in a sleeving manner; the elastic tube can seal the lateral air holes; and when the air pressure outside the storage chamber is higher than the inside air pressure, and the inside and outside air pressure difference reaches a preset value, the air outside the storage chamber can jack open the elastic tube through the lateral air holes and enters the storage chamber through the space between the elastic tube and the side wall of the core tube. The air pressure balancing device is used for adjusting the inside and outside air pressure of the refrigeration device.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air pressure balance device and a refrigeration device. Background technique [0002] At present, refrigeration devices such as refrigerators or freezers are more and more used by people because they can store food in any season due to the cooling of their inner chambers. With the continuous improvement of the production process level, the sealing performance of the inner chamber of the refrigeration device has been greatly improved. However, when the refrigeration device is refrigerated for a period of time, because the temperature of the inner chamber drops, the internal air pressure will also drop. At this time , the atmospheric pressure is greater than the air pressure in the inner cavity of the refrigeration device to form a pressure difference, which acts on the door of the refrigeration device. At this time, when the door of the refrigeration device is opened, it ...
