Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] refer to figure 1 , figure 1 It is a schematic flow chart of an embodiment of the refrigerator temperature control method of the present invention; figure 1 As shown, the refrigerator temperature control method in this embodiment includes the following steps:

[0041] Step S10 , in the normal freezing mode of the refrigerator, acquire the temperature value inside the refrigerator every preset time period.

[0042] Because the freezer needs to refrigerate food for a long time to prevent food from going bad, it generally operates in a regular freezing mode. When the freezer is opened or more food is put in, the temperature inside the freezer will rise. In this embodiment, by detecting the temperature inside the freezer, it is judged whether the freezer has been opened or more food has been put in. . Wherein,...

Abstract

The invention discloses a refrigerator temperature control method and device. The method includes: under a conventional freezing mode of a refrigerator, the temperature inside the refrigerator is obtained every other preset time period; when the currently detecting temperature T1 and the detected temperature feature value away from the current preset time period are larger than a temperature change threshold, a compressor is controlled to operate at a first preset speed to allow the refrigerator to enter a quick freezing mode; under the quick freezing mode, when the operation state of the refrigerator reaches the preset condition for quitting the quick freezing mode, the compressor is controlled to operate at a second preset speed to allow the refrigerator to return to the conventional freezing mode, wherein the second preset speed is smaller than the first preset speed. The invention further discloses a refrigerator temperature control device. By the refrigerator temperature control method and device, the refrigerator can enter or quit the quick freezing mode automatically according to temperature change, manual operation is not needed, great convenience is achieved, electric energy can be saved, and the service life of the compressor can be prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to a method and device for controlling the temperature of a refrigerator. Background technique [0002] At present, the quick-freezing function of the freezer is turned on and off manually. Generally, when a large amount of food is put in, it is necessary to turn on the quick-freezing mode to protect the food, and when the temperature drops to a certain temperature, it is necessary to exit the quick-freezing mode to prevent the food from freezing, which is very inconvenient, and when the user forgets to turn it on or off When the freezer is in the quick freezing mode, the compressor will be running all the time, which not only causes waste of electric energy, but also affects the service life of the compressor. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is ...
