Refrigerator

Abstract

The invention relates to a refrigerator which comprises a refrigerating chamber (10) used for preserving vegetables and fruits, a moisturizing material (21) arranged in the refrigerating chamber and made of a porous material, a tray (22) used for bearing the moisturizing material (21) in the refrigerating chamber, a water storage tank (11) for storing humidifying water, a humidity sensor (25) used for detecting the humidity of the refrigerating chamber (20) and a control part (40) used for controlling an ejector to add water into the moisturizing material according to the humidity detected by the humidity sensor, wherein the water storage tank comprises a pump (12) for sucking water from the water storage tank, an ejector (23) for adding the water into the moisturizing material and a water supplying mechanism connected with a pipeline of the pump and the ejector. Control is carried out by the control part, when the humidity of the refrigerating chamber is overlow, the water is added into the moisturizing material by the water supplying device, the refrigerating chamber is humidified by using the evaporation of the water absorbed by the moisturizing material to ensure that vegetables and fruits in the refrigerating chamber can be preserved for a long time.

Description

technical field [0001] The present invention relates to a refrigerator, and more specifically, provides a refrigerator capable of keeping a refrigerating room in a specified humidity range and keeping fruits and vegetables fresh for a long time. Background technique [0002] In the past, as a means of maintaining the humidity in the refrigerator compartment, it has been disclosed that, for example, a spray type humidification nozzle is installed in the refrigerator compartment, and by detecting the humidity in the refrigerator compartment, when the humidity threshold in the refrigerator compartment is reached, the spray head is used to spray into the refrigerator compartment. [0003] In the above-mentioned prior art, although the refrigerating room can be kept within a specified humidity range to achieve the purpose of keeping fruits and vegetables fresh, the method used is to spray directly into the refrigerating room, and the sprayed water droplets are very fine, but still...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned prior art, although it is possible to keep the refrigerated room within a specified humidity range to achieve the purpose of keeping vegetables and fruits fresh, the method used is to spray directly into the refrigerated room, and the sprayed water droplets are very fine, but still Water droplets will directly adhere to the fruits and vegetables

Although it can maintain the humidity in the refrigerator to achieve the purpose of keeping fresh for a certain period of time, but because the water droplets are directly attached to the fruits and vegetables, it will cause the fruits and vegetables to rot after a relatively long period of time.

For vegetables and fruits that are in transit and will be sold soon, they can keep their freshness, but it is not conducive to long-term preservation

[0004] Moreover, due to the way of direct spraying for humidification, it is easy to condense more water in the refrigerator, which is not conducive to the cleaning of the refrigerator.

[0005] In addition, in the above-mentioned prior art, in order to achieve a good spray effect and obtain finer water mist as much as possible, it is necessary to use a nozzle with a complicated structure, so the cost is increased, and it is not suitable for humidification of household refrigerators.
