Drying device, refrigerator and desiccant recovery method

Abstract

The invention relates to a drying device, a refrigerator and a drying agent recovering device. The drying device comprises a device body, a drying portion and a heating device. The device body is provided with an airflow inlet and a dried airflow outlet which are communicated with the interior of a drying room in a controlled mode, and further provided with a humid airflow outlet communicated with the exterior of the drying room in a controlled mode. The drying portion contains drying agents and is arranged to dry gas entering the device body through the airflow inlet. Dried gas flows out of the drying device through the dried airflow outlet. The heating device is arranged to heat the drying agents so as to evaporate moisture adsorbed by the drying agents. At least some steam evaporated out flows out of the drying device through the humid airflow outlet. The drying device can heat and regenerate the drying agents inside the drying device and is easy and sanitary to operate, drying agent bags are prevented from being manually added or replaced or moved out, and the service life of the drying agents is significantly prolonged.

Description

technical field [0001] The invention relates to drying of gas, in particular to a drying device, a refrigerator and a method for recovering desiccant. Background technique [0002] The popularity rate of refrigerators in our country is very high. With the improvement of people's living standards, the function of refrigerators is not only to store basic green leafy vegetables, fruits and meat. Refrigerators need to have an independent space with low temperature and low humidity for storage. Dry goods and other food, so as to better preserve food, the independent space with this function can be called dry goods area or drying room. In this independent space, we store tea, shiitake mushrooms, ginseng, antler, cordyceps and other valuable dry goods. [0003] At present, the method that can effectively realize a low-temperature and low-humidity environment is mainly to add a desiccant package, such as activated carbon and / or silica gel, in the drying chamber of the refrigerator....

AI Technical Summary

Problems solved by technology

However, this method requires manual addition, replacement or removal of the desiccant cartridge, which is cumbersome, unhygienic, and has a short service life

In addition, this method cannot accurately and effectively regulate and visualize the humidity in the drying room.
