How to control the refrigerator

Abstract

The invention provides a refrigerator and a control method thereof. The refrigerator comprises a box body, a plurality of chambers, a refrigerating system and a control mechanism, wherein the plurality of chambers are arranged in the box body, the refrigerating system is used for providing the refrigerating capacity for the chambers, and the control mechanism is electrically connected with the refrigerating system; each chamber comprises a refrigerating chamber, a freezing chamber and a variable-temperature chamber, wherein the freezing chamber and the variable-temperature chamber are adjacently arranged; the refrigerator further comprises an air supply channel, an air return channel, temperature sensing elements, variable-temperature fans and freezing fans, wherein the air supply channelis used for supplying cool to the freezing chambers and the variable-temperature chambers through the refrigerating system, the air return channel is used for air returning, the temperature sensing elements are used for sensing indoor temperature, and the variable-temperature fans and the freezing fans are arranged in the variable-temperature chambers and the freezing chambers respectively, the freezing chambers and the variable-temperature chambers communicate with the refrigerating chambers through first air doors and second air doors respectively so as to supply cool to the refrigerating chambers, the fans, the temperature sensing elements, the first air doors and the second air doors are connected with the control mechanism. By the arrangement, the air circulation time of the variable-temperature chambers is prolonged, and frosting is avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for controlling a refrigerator. Background technique [0002] Currently commonly used T-door refrigerators with variable temperature chambers have a temperature range of -5~-18°C. The upper part of the refrigerator is a refrigerating chamber, and the lower two chambers are respectively a freezing chamber and a temperature-changing chamber. When the set temperature of the variable temperature chamber is relatively high and the ambient temperature is relatively low, due to the heat conduction effect of the freezer, the variable temperature chamber can reach the set temperature within a short time of blowing. At this time, the variable temperature chamber is equivalent to a direct cooling refrigerator. The hot air leaks into the cooling room through the door seal and then naturally convects to the top of the tank to form frost. For traditional refrigerators w...

AI Technical Summary

Problems solved by technology

For traditional refrigerators with variable temperature chambers, when the variable temperature chamber is set to a higher temperature, in order to suppress the impact of the freezer on the heat conduction of the variable temperature chamber, additional heating wires are generally attached inside the chamber, because the efficiency of electric heating wires is relatively low. , which brings about a great waste of energy. In addition, due to the natural convection of hot air, it will also lead to uneven temperature distribution in the warming room.
