Nitrogen production control method and device for refrigerator

Abstract

Provided are a nitrogen generation control method and apparatus for a refrigerator. A sealed space is arranged in a storage compartment of a refrigerator, and the refrigerator is provided with a nitrogen generation apparatus (102) for providing nitrogen for the sealed space. The nitrogen generation control method for a refrigerator comprises: obtaining a time period in which the number of opening times of a sealed space exceeds a preset threshold and a running time point of the refrigerator; and determining whether the running time point falls within the time period or whether the time length from the running time point to the starting point of the time period is less than a first preset time threshold, and forbidding opening of the nitrogen generation apparatus (102) of the refrigerator until the time period ends on condition that a result of any determining is yes. By means of the control method, the nitrogen generation apparatus (102) is prevented from being turned on in a frequent opening time period of the sealed space by a user or when the time period is approaching, thereby effectively preventing nitrogen in the sealed space from losing, and reducing the energy consumption of the refrigerator.

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
