Refrigerator, storage device and control method of storage device

Abstract

The invention relates to a refrigerator, a storage device and a control method of the storage device. The storage device comprises a main body part, an adsorption module, a weight detecting device and a fan, wherein a storage space and an air channel are limited in the main body part; the adsorption module is used for removing ethylene and / or undesirable odors in airflow which flows through the adsorption module; the weight detecting device is used for detecting the weight of goods stored in the storage space; and the fan is configured to operate controllably at an operating frequency which is matched with the weight of the goods stored in the storage space. The control method includes the steps that the weight of the goods stored in the storage space is obtained; the fan is driven to operate at the operating frequency matched with the weight of the goods stored in the storage space, so that the airflow in the storage space returns back to the storage space through the air channel after flowing through the adsorption module. In this way, the situations that the concentration of the ethylene and / or the undesirable odors in partial areas of the storage space is excessively high, and the goods in the storage space are air-dried and dehydrated are avoided. The refrigerator comprises the storage device and a refrigerator body.

Description

technical field [0001] The invention relates to a storage device, in particular to a refrigerator with a storage device, a storage device and a control method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the logistics industry has also developed rapidly, so that fruits and vegetables (especially tropical fruits) can be transported to various places conveniently and quickly. However, since fruits and vegetables begin to ripen and rot immediately after picking, and most fruits and vegetables are sensitive to the plant hormone ethylene, it is difficult to preserve them. [0003] In order to solve this problem, there is a fresh-keeping device with the function of removing ethylene and peculiar smell in the prior art, which cooperates to purify the air in the cooling fresh-keeping device by setting a circulating fan and an activated carbon fiber filter with the function of absorbing ethylene. Nevertheless, the circula...

Problems solved by technology

On the one hand, if there are many fruits and vegetables in the fresh-keeping device, and the constant frequency of the circulation fan is relatively low, that is, the wind speed of the circulation fan is too slow, it is easy to cause the ethylene concentration in some areas such as the surface of the fruits and vegetables to be too high, thereby accelerating the decay of some fruits and vegetables; On the other hand, if there are few fruits and vegetables in the fresh-keeping device, and the constant frequency of the circulation fan is relatively high, that is, the wind speed of the circulation fan is too fast, it is easy to cause the fruits and vegetables to dry out and lose water.

[0004] In addition, since tropical fruits grow in hot areas, they cannot withstand low temperatures, and the temperature in the refrigerator compartment of household refrigerators is usually set at about 4°C to 7°C, which is relatively low for tropical fruits. Affect the taste of tropical fruits, and even cause frostbite of tropical fruits, which is not conducive to the storage of tropical fruits
