Refrigerator having air pressure adjusting apparatus for storage container

Abstract

The present disclosure relates to a refrigerator having an air pressure adjusting apparatus for a storage container, and more particularly, a refrigerator having an air pressure adjusting apparatus for a storage container, capable of uniformly maintaining internal air pressure of the storage container by increasing the internal air pressure by way of an introduction of external air when the internal air pressure is excessively lowered and also preventing damages of the storage container. The refrigerator includes a storage container having an inner accommodating space and installed to be drawn out of and inserted into the refrigerator, and an air pressure adjusting apparatus to allow external air to be introduced into the storage container based on internal air pressure of the storage container, so as to increase the internal air pressure. The refrigerator is capable of preventing damages of the storage container in advance even if the internal pressure is continuously reduced due to a crashed vacuum pump, faults or other reasons.

Description

technical field [0001] The present invention relates to a refrigerator having an air pressure regulating device for a storage container of the refrigerator. Background technique [0002] In general, a refrigerator is a device for keeping food and the like in a refrigerated state for an extended (preservation) period by generating cool air in response to the driving of a refrigeration cycle system installed inside the refrigerator, and The generated cool air is supplied to the refrigerator and freezer. [0003] Refrigerators usually have storage containers for preserving and storing vegetables. Also, when vegetables are usually stored in a refrigerator, the vegetables should be preserved in the freshest state. Therefore, it is important to keep the space used for preserving vegetables in optimum condition. [0004] figure 1 is showing a storage container for a refrigerator according to the prior art. The storage container 10 for a refrigerator according to the related ar...

AI Technical Summary

Problems solved by technology

[0008] However, prior art storage containers for vacuum storage have difficulty in maintaining the internal vacuum level (close to vacuum level) uniformly, and sometimes cause an excessive vacuum level

This can greatly affect the freshness of vegetables and similar items stored in storage containers

[0009] In addition, when the vacuum pump is controlled to maintain a predetermined vacuum degree in the storage container, the vacuum pump may continuously operate due to various reasons such as system breakdown, system failure, etc.

This causes the internal air pressure of the storage container to decrease continuously

As a result, the internal air pressure of the storage container may be in a state of being excessively lowered
