Embodiment Construction
[0015] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to this embodiment are included in the protection scope of the present invention.
[0016] see Figure 1 to Figure 3 It is a preferred embodiment of the present invention. The refrigerator 100 of the present invention has a box body 10 and a door body 20. The box body 10 includes an outer shell 11 composed of a back plate 111, a side plate 112, a top plate 113, and a bottom plate 114, and an inner container 12 arranged in the outer shell 11. Insulation material is also filled between the inner container 12 and the outer shell 11. The refrigerator 100 also has a balance pipe 30 connecting the inside and outside of the box body 10. The balance pipe 30 is formed with an air flow channel with a v...

The invention provides a refrigerator. The refrigerator comprises a case body and a door body; the case body comprises a housing and an inner container, wherein the housing is composed of a back plate, side plates, a top plate and a base plate; the inner container is arranged inside the housing; a heat insulating material is filled between the inner container and the housing; the refrigerator also comprises a balancing pipe communicating with the inside and the outside of the case body; an air flow passage of which the volume is 2L to 6L is formed in the balancing pipe. By adopting the refrigerator disclosed by the invention, the balance of internal air pressure and external air pressure of the case body can be maintained, negative pressure can be eliminated and door opening resistance can be reduced; moreover, air flow disturbance at the opening of the case body can be reduced during opening and closing of the door, acute interaction of cold air and hot air is avoided, and cold loss is reduced.
Description
technical field [0001] The invention relates to the manufacturing field of refrigerators, in particular to a refrigerator capable of ensuring the pressure balance between the interior and exterior of a compartment and effectively reducing the loss of cooling capacity during door opening and closing. Background technique [0002] The compartment of a traditional direct cooling refrigerator is closed after the door is closed, and cannot interact with the outside air. After the temperature drops, the air pressure in the compartment will decrease, making it difficult to open the door of the refrigerator; on the other hand, when the door of the refrigerator is opened and closed, the airflow at the opening of the box is greatly disturbed, and the hot and cold air is violently convected, resulting in the loss of cooling capacity. , power consumption increases. [0003] Aiming at the difficulty of opening the door caused by negative pressure in the low-temperature compartment, vari...
