Problems solved by technology

[0002] There are many electrical equipment in the kitchen, such as range hoods, microwave ovens, electric kettles, etc. Most of these electrical equipment will make noise when they are working, which will bring discomfort to people. When the noise is too loud, people outside the kitchen talking, TV sound May not be able to hear clearly, making the life experience in the kitchen not good
[0003] The use of sound-absorbing materials in the current kitchen decoration is still a small number, and the sound-absorbing materials have requirements for the frequency of noise reduction. All replaced with low-noise equipment, making it difficult to change the status quo of high noise caused by many electrical equipment in the kitchen, which cannot meet the needs of modern smart homes

Embodiment 1

[0074] Include steps:

[0075] Record the combined noise information of each noise in the kitchen;

[0076] Depending on the combined noise information, noise reduction information corresponding to each noise is calculated;

[0077] Query the noise reduction information corresponding to each noise combination.

[0078] N noise devices in the kitchen, when at least one device is in a working state, the total number of arrangements that can be constructed is That is, any of the N devices, any two devices ... arbitrary N-1 devices, all devices consisting of 2 n -1 combination, obtain combined noise information for each combination, and then processes the corresponding 2 according to the combined noise information. n -1 kinds of noise reduction information, when noise reduction, in this 2 n -1 species in the noise reduction information query corresponding noise reduction information.

[0079] By obtaining the operating state of the N devices, it can be determined which combined mode,...

Embodiment 2

[0082] Include steps:

[0083] Record unit noise information of each noise device in the kitchen;

[0084] According to the unit noise information, a combined noise information corresponding to the noise combination of each noise device in the kitchen is calculated;

[0085] The noise reduction information corresponding to each noise is calculated based on the combined noise information.

[0086] When the equipment in the kitchen is too much, the user is not convenient to pre-record all combined combined noise information of all devices, and this embodiment describes a simplified processing scheme, by obtaining unit noise information of each noise device, by calculation The way the combination noise information of any device is obtained. For example, these unit noise information can be demonstrated in the form of a spectrum, and different unit noise information is superimposed in the same time, so that the spectrum of the combined sound can be drawn.

[0087] Further, the step "Ac...

Embodiment 3

[0092] Also include steps:

[0093] Get equipment information for each noise device;

[0094] Device noise information for each noise device is acquired from the server according to the device information;

[0095] Get all noise devices to background noise information for downtime;

[0096] According to the device noise information and the background noise information, a combined noise information corresponding to the noise combination of each noise device in the kitchen is calculated.

[0097] Generally, the same type of electrical appliance is roughly the same as the noise emitted in normal operation, in order to simplify the step of acquiring the user's noise sampling, the information of the device is acquired from the server, or stores some devices corresponding to the device. Noise information, only stores the corresponding device within the record. The device noise information is different from the unit noise information described above in that the unit noise information is ...

Abstract

According to a kitchen noise reduction method, a refrigerator and a computer readable storage medium disclosed by the invention, by playing the noise reduction sound waves corresponding to the combination of the noise equipment in the working state, active noise reduction only aiming at the noise generated by the electric appliance which is running in the kitchen is realized; the sound of speaking, television sound, normal background sound and the like of others are not eliminated, on one hand, a kitchen is quiet, on the other hand, sound which does not need noise reduction is reserved, the intelligent degree is high, stable noise is generated by electrical equipment generally, the noise reduction effect on the noise is obvious, the use experience of a user in the kitchen is greatly improved, and the requirements of smart families are also met.

Description

Technical field [0001] The present invention relates to the field of noise reduction, and more particularly to a kitchen noise reduction method, a refrigerator and a computer readable storage medium. Background technique [0002] More electrical equipment in the kitchen, such as hood, microwave, electric kettle, etc. It may be unclear, making the life experience in the kitchen operation. [0003] The current use of sound absorbing materials in the kitchen decoration is still a small number, and the sound absorbing material has the frequency of noise noise reduction, its noise reduction effect is limited, and all the electrical equipment that the user cannot control can operate low noise, and all electrical equipment cannot be used. All replaced with low noise equipment, which makes it difficult to change the current status of the kitchen inner electrical equipment, which cannot meet the needs of modern intelligent home. Inventive content [0004] To solve problems in the prior a...
