Embodiment Construction

[0019] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0020] The food freshness detection method that this application proposes, such as figure 1 shown, including the following steps:

[0021] Step S11: Obtain the type information of the detected food.

[0022] In this application, the food category information is used as a known item, which can be input by the user through the input device before putting the food in the refrigerator, or determined by the fixed area inside the refrigerator according to the food category. The input of the specific food category The method is not limited by the embodiment of this application.

[0023] Step S12: Measure the quality of the tested food.

[0024] Install pressure sensors and other equipment that can measure the quality of food in the area where the refrigerator is used to detect the freshness of food. Before the food is put ...

Abstract

The invention discloses a food freshness detecting method and device, a refrigerator and a detecting system. Variety information of detected food is obtained, the quality of the detected food is measured, the characteristic gas concentration, measured through a smell sensor every a set time, of the interior of the space where the detected food is located is received, and then freshness grade information of the detected food is determined on the basis of the corresponding relation between the variety, the quality and the characteristic gas concentration of the detected food and the food freshness grade. The corresponding relation is integrated or stored in a storage module of the refrigerator or stored in a cloud platform; owing to the fact that the food freshness grade inquired through the variety, the quality and the characteristic gas concentration of the food is relevant to the food quality, the characteristic gas concentration can be accurately reflected, that is, the food freshness grade can also be accurately determined, and therefore, the technical problem that existing detecting for the food freshness grade is inaccurate is solved.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a method, a device and a refrigerator for detecting the freshness of visual food. Background technique [0002] The popularization of refrigerators facilitates the storage of daily food for users, and the preservation of food taste, nutrition and freshness can improve users' experience of refrigerators, thereby improving the product quality of refrigerators. [0003] Under normal circumstances, users can judge the freshness of food subjectively by the change of food appearance, color and smell. When the freshness has been reduced, in order to remind the user to eat the stored food within the optimal time limit, there is a way to judge the freshness of the food by detecting the gas concentration emitted when the food rots through an odor sensor or an electronic nose in the prior art. The principle is to establish a database of the gas concentra...
