Description

An adjustable humidity device for refrigerators and air-cooled refrigerators

technical field

The utility model relates to the technical field of refrigeration equipment, in particular to an adjustable humidity device for a refrigerator and an air-cooled refrigerator.

Background technique

Factors affecting the preservation effect include microorganisms, temperature, humidity, oxygen, ethylene, etc. Humidity, as an important influencing factor, is particularly prominent for the preservation effect of food. Food that needs to be stored in a high-humidity environment, such as vegetables, will easily lose water and wilt if it is stored in a space with unsuitable humidity for a long time, which will seriously affect its quality and appearance. Foods that need to be stored in a low-humidity environment, such as tea and Chinese herbal medicines, are prone to mold and deterioration if there is no suitable humidity. Therefore, adopting different humidity levels for different foods is particularly important for freshness and quality preservation.

At present, some relevant manufacturers in the industry have proposed the concept of dry and wet storage to provide different storage spaces for different ingredients. The moisture-permeable and moisturizing film is used in the wet area, and the micro air duct or drying module is used in the dry area, but neither of them can accurately control the humidity. Even if there is space for dry-wet conversion or dry-wet multiplexing, the humidity can only be adjusted within a narrow range. Unable to meet the increasing needs of users.

detailed description

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

Referring to FIG. 1 , this embodiment discloses an air-cooled refrigerator, which includes a refrigerating room 1 and a freezing room 2 . A refrigerating door is provided on the front side of the refrigerating room 1 , and a display control panel 14 is provided on the refrigerating door. The back of the freezer compartment 2 is provided with an evaporator cavity, and the evaporator cavity is provided with a refrigerating evaporator 3 and a cooling fan 4. The back of the freezer compartment 1 is provided with a refrigerating air inlet duct 12, and the lower end of the refrigerating air intake duct 12 communicates with the evaporator cavity. , The upper end communicates with the refrigerating room 1 through the refrigerating air inlet 13, and the refrigerating room 1 is provided with an adjustable humidity device.

The adjustable humidity device includes a box body 5 with a storage cavity 6. The box body 5 is provided with a moisturizing module 7 and at least one humidity sensor 11. The moisturizing module 7 can be an ultrasonic humidification module or a nano atomization module. The moisturizing module 7 It is arranged on the upper part of the storage cavity 6 of the box body 5, which is conducive to the sinking of moisture. There is a certain distance between the humidity sensor 11 and the moisturizing module 7 to prevent the humidity sensor 11 from being affected by the moisturizing module 7 when it is working. One side of the box body 5 is provided with an air inlet 8, and the outside of the air inlet 8 communicates with the refrigerated air inlet 12 of the refrigerator through an independent air duct 9, and an electric damper 10 is arranged inside the independent air duct 9, and the opening of the electric damper 10 Or closed to realize the selective delivery of low-temperature and low-humidity airflow from the refrigerated air inlet duct 12 to the box body 5, and control the electric damper 10 according to the humidity sensor 11 detecting whether the humidity in the storage cavity 6 of the box body 5 reaches the preset humidity And the opening or closing of moisturizing module 7.
