Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1 and 2, the pressure balancing device for the refrigerator includes a connection assembly provided on the refrigerator 5;

the connecting assembly comprises a first connecting pipe 11 and a second connecting pipe 12, one end of the first connecting pipe 11 is communicated with the refrigeration house 5, and the other end of the first connecting pipe is obliquely arranged downwards and communicated with one end of the second connecting pipe 12;

the middle part of the second connecting pipe 12 is positioned at a low position and is bent to form a communicating vessel structure, regulating liquid is stored in the middle part, and a water outlet 16 which is arranged downwards is arranged at the other end close to the port;

the position of the water outlet 16 is lower than the end of the first connecting pipe 11 connected with the refrigeration house 5;

further, the first connecting pipe 11 is movably communicated with the refrigeration house 5 in a sealing way, and the axis of the first connecting pipe and the vertical direction form an included angle of 20-60 degrees; the included angle between the axis of the first connecting pipe 11 and the vertical direction can be adjusted through the movable connection of one end of the first connecting pipe 11, so that when cooling gas is condensed at the first connecting pipe 11, condensed water can better flow into the first connecting pipe 11, the collection of the condensed water is realized, and the condensed water is prevented from being fed back into the refrigeration house 5 to cause the condensation of the inner wall of the refrigeration house 5;

further, the second connecting pipe 12 is of a V-shaped or U-shaped structure, and one end of the second connecting pipe is provided with a gas-permeable sealing end cover 15. Through the V-shaped or U-shaped structure of the second connecting pipe 12, the regulating solution is stored better, the second connecting pipe 12 is convenient to process, the cost is reduced, and the end cover is arranged at the other end, so that the internal and external pressure of the second connecting pipe 12 is effectively balanced, and the regulating solution is prevented from being polluted by the outside;

furthermore, a sensing device 4 is arranged in the second connecting pipe 12, the sensing device 4 is a temperature sensor or a pressure sensor, the corresponding sensing device 4 is in contact with the regulating liquid or is positioned between the first connecting pipe 11 and the regulating liquid and is connected with a controller, and the controller controls the action of the alarm device;
