Abstract
The invention provides a method for detecting food freshness in a refrigerator, which comprises an odor sensor, a controller, a storage module, a display module and a sound reminding module, wherein the odor sensor, the storage module, the display module and the sound reminding module are all in communication connection with the controller; the method comprises the following steps: the odor sensor stores laboratory data of each food into the storage module through the controller; the odor sensor collects data of food in the refrigerator, and the controller processes the collected data and stores the processed data in the storage module; the controller compares the processed data with laboratory data stored in the storage module, calculates the current freshness value of the food through an algorithm, can display the current freshness data of the food according to a display instruction of a user, and can send a reminding signal when the food is not fresh. The invention can accurately detect and monitor the freshness of food in the refrigerator in time and improve the life quality of people.
Description
Technical field
The present invention relates to refrigerator control technology fields, and in particular to a method of food freshness in detection refrigerator.
Background technique
Refrigerator is as storage food and postpones the household electrical appliance of food spoilage time, has become the indispensable family of average family
Electricity.Currently, refrigerator in the market is still to store based on food, the exploitation of corresponding other function is also very limited.For example, if
Whether the food stored in refrigerator occurs rotten or peculiar smell occurs, and opening refrigerator that at present can only be artificial is judged, but new
Fresh and fresh degree can not all perceive, if user forgets that, there are certain food in refrigerator, the food is rotten in refrigerator mesometamorphism
Rotten user can not also know.Requirement with the mankind to quality of life is higher and higher, and food is new in the refrigerator of detection display in time
Fresh degree will become trend.
Summary of the invention
In order to solve the above technical problems, the purpose of the present invention is to provide a kind of sides of food freshness in detection refrigerator
Method, this method can promptly and accurately detect the freshness of food in refrigerator, improve people's quality of life.
To achieve the above object, the present invention provides a kind of method for detecting food freshness in refrigerator, and this method is used
Device includes smell sensor, controller and memory module, the smell sensor, memory module with controller communication link
It connects；Method includes the following steps:
The laboratory data of each food is stored into memory module by controller by S1, smell sensor；
S2, smell sensor acquire the data of food in refrigerator；
S3, controller pre-processes the data that smell sensor acquires, and is stored into memory module；
The laboratory data stored in pretreated data and memory module is compared by S4, controller, passes through algorithm meter
Calculate the current grade of freshness of the food.
As a further improvement of the present invention:
This method institute use device further includes display module and sound reminding module；This method is further comprising the steps of:
S5, when the current grade of freshness of the food drops to a certain threshold value, controller controls display module and sound prompting mould
Block issues alarm signal.
This method is further comprising the steps of: S6, and the idsplay order that controller is inputted according to user is shown by display module
The current freshness data of the food.
From the above technical scheme, the present invention provides a kind of method of food freshness in detection refrigerator, this method
The freshness of food in refrigerator can be promptly and accurately detected, and can be by means of display module, sound prompting module, according to user's need
It wants, shows that the freshness of food in refrigerator can be with especially when food freshness value is less than a certain threshold value to user in real time
User is reminded by alarm module, facilitates user to detect food freshness in monitoring refrigerator, improves people's quality of life.
Detailed description of the invention
Fig. 1 is step flow chart of the invention.
Specific embodiment
In conjunction with attached drawing, the present invention will be further described:
The embodiment of the present invention as shown in Figure 1, this method institute use device include smell sensor, controller, display module,
Sound prompting module and memory module, the smell sensor, display module, sound prompting module and memory module with
Controller communication connection；Method includes the following steps:
The laboratory data of each food is stored into memory module by controller by S1, smell sensor；The laboratory of each food
Initial data of the data from engineering experience, as comparison；
S2, smell sensor acquire the data of food in refrigerator；
S3, controller pre-processes the data that smell sensor acquires, and is stored into memory module；Due to smell sensor
The data of refrigerator inside environment are acquired, noise is had, needs first to carry out denoising；
The laboratory data stored in pretreated data and memory module is compared by S4, controller, passes through algorithm meter
Calculate the current grade of freshness of the food；
S5, when the current grade of freshness of the food drops to a certain threshold value, controller passes through display module and sound prompting mould
Block issues signal, reminds user's food no longer fresh；Preferably, sound prompting module uses music buzzer；
S6, if the current freshness of food does not drop to a certain threshold value, controller judges whether user passes through user input interface
Idsplay order is had input, if so, the current grade of freshness of the calculated food is shown by display module.
In specific use, it can recycle and carry out step S2 to S6, so as to the freshness of food in real-time monitoring refrigerator.When
So, it can also be recycled with setting time interval and carry out step S2 to S6.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
