Problems solved by technology
[0005] However, there are some problems in the above-mentioned method of adjusting the noise of the range hood to the user's satisfaction level: first, because the noise detection sensor is not clearly set on the range hood, the internal noise value of the range hood detected by it cannot be true. The current operating status of the range hood can be accurately reflected; secondly, the adjustment of the air volume of the range hood is still based on the adjustment scheme that has already been set up, and it is impossible to realize the self-adaptive adjustment between the air volume of the range hood and the operating noise value of the range hood
However, since the noise reduction method of the invention patent application CN108731045A needs to always ensure that the real-time amplitude of the generated noise reduction is the same as the real-time operating noise amplitude of the oil suction machine, this requires the use of precise noise filtering technology to remove other external noises for oil suction The interference of the noise of the hood will undoubtedly increase the difficulty of technical realization and the manufacturing cost of the hardware noise reduction device

Embodiment Construction
[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0049] like figure 1 As shown, this embodiment provides an intelligent adjustment method for range hood noise, which specifically includes the following steps 1 to 9:
[0050] Step 1, pre-establish the ideal speed-noise relationship list between the operating speed and noise range value corresponding to the range hood in the ideal operating state; wherein, the operating speed and noise range values in the ideal speed-noise relationship list are one by one Corresponding; the "ideal operating state" mentioned here refers to the operating state of the range hood at its rated power; it is generally believed that the noise generated by the range hood when it is operating at the rated power will not affect the user's experience. Negative Effects;
[0051] For example, assume that in the ideal speed-noise relationship list established, the operat...

The invention relates to an intelligent adjustment method for the noise of a range hood, which pre-establishes an ideal speed-noise relationship list between the corresponding operating speed and the noise range value of the range hood in an ideal operating state, and detects the air inlet of the range hood. The real-time external noise value of the range hood and the real-time operating noise value of the range hood during stable operation can be accurately obtained by combining the internal and external noise of the range hood to obtain the real value of the operating noise of the range hood; When it is determined that there is a user under the range hood, adjust the current operating speed of the range hood to the operation corresponding to the actual value of the operating noise in the ideal speed-noise relationship list The speed realizes that the speed of the range hood can be adjusted according to the noise generated by it, so as to adjust the noise of the range hood to the noise range under the ideal state, so as to avoid affecting the user's experience.
Description
technical field [0001] The invention relates to the field of range hoods, in particular to an intelligent adjustment method for the noise of the range hood. Background technique [0002] As people pay more attention to the quality of life at home and their health, range hoods have become an essential equipment in people's kitchens. At the same time, due to the continuous improvement of users' requirements for cooking environment and cooking experience, range hoods no longer only have a single suction and exhaust function. [0003] As we all know, during the working process of the range hood, its air volume and noise are two parameters that show "one trades off and the other trades off". As the two most important indicators to measure the comprehensive ability of the range hood, the two parameters of air volume and noise cannot be neglected. Taking into account the differences in usage habits, groups of users and usage environments of different users, the air volume and noi...
