AI Technical Summary

Technical Problem

In existing technologies, a single sealed storage drawer cannot simultaneously achieve both high humidity and low humidity modes, making it difficult to meet the different storage needs of fruits, vegetables, and dried goods.

Method used

Design a humidity regulating device that includes a moisture-permeable component and a moisture-absorbing component. A sliding switching mechanism can be used to selectively cover the installation port of a storage drawer to achieve switching between high humidity mode and low humidity mode. Combined with the design of air inlet and air outlet, hot air is used to dry and regenerate the moisture-absorbing component.

Benefits of technology

It enables quick switching between high humidity and low humidity modes in the same storage drawer, has a compact structure, is easy to operate, improves the space utilization of refrigeration equipment, and meets the storage needs of different food ingredients.

Abstract

The application provides a humidity adjusting device and a refrigeration equipment. The humidity adjusting device comprises a storage drawer arranged in a refrigeration chamber of the refrigeration equipment. A drawer panel is arranged on the top of the storage drawer. The drawer panel comprises an upper cover plate and a lower bearing plate arranged oppositely. A gap is formed between the upper cover plate and the lower bearing plate. An installation opening is formed on the lower bearing plate and used for connecting the gap and the inside of the storage drawer. The humidity adjusting mechanism comprises a moisture permeable component and a moisture absorbing component arranged in the gap and connected with each other. The moisture permeable component and the moisture absorbing component are accommodated in the gap. A switching mechanism is slidably arranged on the upper cover plate and connected with at least one of the moisture permeable component and the moisture absorbing component. The switching mechanism is used for moving the moisture permeable component or the moisture absorbing component to the installation opening and covering the installation opening. The humidity adjusting device provided by the application can realize the high humidity mode and the low humidity mode at the same time, and has simple structure and convenient operation.
