Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of refrigeration equipment, and particularly relates to a pressure relief structure for a refrigerator door handle and a refrigerator. Background Art
[0002] A refrigerator is a device that maintains a constant low temperature to store items and extend the storage time of the items. A refrigerator generally includes a box body and a box door. An internal space for storing items is formed inside the box body, and the box door is pivotally provided on the box body so as to be able to open or close the internal space of the box body, thereby facilitating storing or taking out items in the internal space of the box body.
[0003] When the refrigerator is in the refrigeration state, after the box door is opened, hot air outside the refrigerator enters the box. At this time, when the box door is closed again, the hot air that has entered the box shrinks sharply due to cooling. Since the refrigerator is a container with good airtightness, a large negative pressure will be formed inside the box. If the box door is opened again before the negative pressure disappears, the resistance generated by the negative pressure needs to be overcome, so a large pulling force is required to open the door. It is difficult to open the box door, and sometimes it is even impossible to open the box door. Forcibly opening the door may cause damage to the box door or the box body. Summary of the Invention
[0004] The purpose of the present invention is to provide a pressure relief structure for a refrigerator door handle and a refrigerator.
