Embodiment 1

[0026] The structural reference of the freezer of the present embodiment Figures 1 to 3 , including a cabinet body 1, and an air duct structure that forms a first air curtain and a second air curtain in the cabinet frame at the opening of the cabinet body 1, and the air duct structure includes a circulating air duct arranged on the wall of the cabinet body 1 11. The evaporator 2 and the first fan 4 are arranged in the circulating air duct 11. One end of the circulating air duct 11 is provided with an air inlet 33, and the other end of the circulating air duct 11 is respectively provided with first and second air outlets 31 and 32. , the first and second air outlets 31, 32 are located at the top of the cabinet frame at the opening of the cabinet body 1, the air inlet 33 of the circulating air duct 11 communicates with the inner cavity of the cabinet body 1, and the openings of the first and second air outlets 31, 32 are vertical The horizontal plane faces downward, and the fir...

Embodiment 2

[0030]The freezer structure of this embodiment is similar to that of Embodiment 1, the difference is that: the air inlet 33 of the above-mentioned circulating air duct 11 is located on the rear inner wall of the cabinet body 1, and the first blower fan 4 is a variable direction fan, and the variable direction fan can be used. Realize the two-way flow of air in the circulating air duct 11, so that the air in the cabinet circulates back and forth. In the closed state, the first fan 4 is controlled to rotate in the direction of closing the door (for example, clockwise), so that the air is sucked into the circulating air duct 11 from the first and second air outlets 31, 32, and then passes through the evaporator 2 and then flows out of the circulating air duct 11. The air inlet 33 is discharged into the cabinet, and through continuous circulation, the cabinet maintains a certain range of temperature and humidity, such as Figure 4 As shown (the arrow indicates the direction of the...

Embodiment 3

[0032] The freezer structure of this embodiment is similar to that of Embodiment 2, the difference is: in order to make the temperature gradient difference of the airflow that the first and second air outlets 31, 32 flow out, the temperature of the airflow that flows out from the second air outlet 32 ​​is higher than that of the first airflow. The temperature of the airflow flowing out of the first air outlet 31 ensures that the temperature of the second air curtain is higher than that of the first air curtain, reducing the water vapor formed outside the cabinet from entering the cabinet. The above-mentioned circulating air duct 11 corresponds to the second air outlet 32 ​​and the evaporator An air mixing chamber 111 is provided in the air passage between the two sections, one end of the air mixing chamber 111 communicates with the circulating air duct 11, the other end of the air mixing chamber 111 communicates with the second air outlet 32, and the air mixing chamber 111 is pr...

Abstract

The invention discloses a refrigerator and a control method thereof. The refrigerator comprises a refrigerator body, wherein the refrigerator body is provided with an air duct structure enabling an open part of the refrigerator body to form a first air curtain and a second air curtain; the first air curtain is located at the outer side of the second air curtain; and the temperature of the second air curtain is higher than that of the first air curtain. According to the refrigerator disclosed by the invention, the first air curtain and the second air curtain are formed on a refrigerator frame of the refrigerator body, and are capable of preventing internal temperature and humidity, and external temperature and humidity from direct exchange in an open state of a refrigerator door; because the temperature of the first air curtain located at the outer side is low, a cold moisture layer is formed after mixing of the first air curtain and external damp and hot air, and contains lots of moisture; and the second air curtain located at the inner side and with the high temperature is capable of forming a layer of protection and preventing moisture from entering the refrigerator body, thus the stable changes of the temperature and humidity in the refrigerator within a certain range after the refrigerator door is opened, are ensured.

Description

technical field [0001] The invention belongs to the field of refrigeration, and in particular relates to a refrigerator and a control method thereof. Background technique [0002] At present, all freezer products on the market can only ensure that the temperature and humidity in the cabinet are within a certain range of requirements only after the freezer is closed and running or when the climate is relatively moderate. In the humid rainy season in the south and the cold winter in the north, the humidity and temperature change drastically after opening the door for one minute (the operating time for storing and taking things). Especially for refrigerators used to store special products such as medicines, it is especially important to maintain the stability of the temperature and humidity inside the cabinets. Drastic changes in humidity and temperature may cause the medicines to fail and deteriorate, which in turn affects the lives of patients, causing major medical accident...
