Nitrogen generation control method and device of refrigerator

Abstract

The invention provides a nitrogen generation control method and device of a refrigerator. A seal space is arranged in a storage compartment of the refrigerator, the refrigerator is provided with a nitrogen generation device for providing nitrogen for the seal space, and the nitrogen generation control method of the refrigerator comprises the steps that the time quantum that the opening frequency of the seal space exceeds the preset threshold value and the running moment of the refrigerator are obtained; and whether the running moment is within the time quantum or not or time of the starting point from the running moment to the time quantum is smaller than the first preset time threshold value or not is judged, under the condition that the judgment result is yes, opening of the nitrogen generation device of the refrigerator is forbidden until the time quantum is finished. According to the scheme, the opening time of the nitrogen generation device of the refrigerator can be controlled, a user can be prevented from opening the nitrogen generation device in the time quantum that the seal space is frequently opened or at the time close to the time quantum, nitrogen in the seal space can be effectively prevented from losing, energy consumption of the refrigerator is reduced, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a nitrogen production control method and device for a refrigerator. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a lot of items and put them in the refrigerator, but for leafy vegetables and melons and fruits, the low temperature in the refrigerator room is not only It will cause wrinkles and spots on the skin of these foods, and also affect their original taste and nutrition. [0003] Nitrogen, as a colorless, non-toxic, odorless inert gas, has been widely used in the field of food preservation. Filling the storage compartment of the refrigerator with nitrogen to balance the carbon dioxide and oxygen in it can effectively delay the storage. Oxidative deterioration and decay, so as to achieve food preservation. [0004] In the prior ar...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the nitrogen production control can be carried out according to the established procedure through the concentration sensor, but there are the following disadvantages: the refrigerator performs the nitrogen production control according to the actual concentration value and the set concentration value of each room, so the nitrogen production process may occur at any time, and there are The nitrogen production process may be completed just before the user opens the refrigerator door to pick and place food, and part of the nitrogen generated during this nitrogen production process will be lost and wasted due to the opening of the refrigerator door, increasing the energy consumption of the refrigerator and affecting the user experience
