Gas concentration early warning method, gas concentration early warning device and refrigerator

Abstract

The invention provides a gas concentration early warning method, a gas concentration early warning device and a refrigerator. The gas concentration early warning method comprises the steps that the current gas concentration in the refrigerator is detected through a gas concentration sensor every preset interval; according to the preset interval, the weight of objects stored in the refrigerator, the free space volume of the refrigerator and the current gas concentration, the rising acceleration of the current gas concentration is calculated; whether the rising acceleration of the current gas concentration reaches an early warning concentration threshold value or not is determined; and when it is determined that the rising acceleration of the current gas concentration reaches the early warning concentration threshold value, gas concentration early warning is given. According to the technical scheme, the freshness of the objects stored in the refrigerator can be identified accurately so that a user can treat the objects stored in the refrigerator in time, in this way, air in the refrigerator is prevented from being polluted by foul smell caused by putrefaction of the stored objects, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a gas concentration early warning method, a gas concentration early warning device and a refrigerator. Background technique [0002] Refrigerators are the most commonly used household appliances in people's daily life. One of the important functions of refrigerators is to manage food and then manage the health of users. However, users will find in the process of using the refrigerator that the refrigerator at home will inevitably produce some odors, and due to the infrequent opening of the refrigerator door and the high humidity environment in the refrigerator, the odor in the refrigerator has a strong retention . Some smells can cause people's sensory discomfort, but also affect the original taste of food and even pollute the indoor air. [0003] The most important reason for the odor in the refrigerator is the peculiar smell emitted after the food deteriorates. T...

Problems solved by technology

The significant disadvantage of this method is that when the camera is obscured by the food, the food photo cannot be delivered

[0008] 4. Gas: The relevant technology is not based on the actual situation. It does not consider the impact of refrigerators with different volumes and different weights of food on the warning concentration threshold. At the same time, it does not consider the problem that refrigerators often open the door during use, so they cannot be used on refrigerators.
