Range hood filter net monitoring device and method

Abstract

The invention relates to a range hood filter net monitoring device and method. The range hood filter net monitoring device comprises a smoke monitoring device, a filter net state monitoring device, acentral controller and a user interaction device; and the central controller is connected with the smoke monitoring device, the filter net state monitoring device and the user interaction device. By monitoring real-time smoke concentration data nearby a range hood, according to the monitored real-time smoke concentration data and the gear of an air damper of the range hood, operating air volumes and the actual total amount of oil smoke flowing through a filter net at all moment points are calculated; aiming at a preset oil smoke cumulant threshold value of the filter net, according to the actual total amount of the oil smoke flowing through the filter net and the preset oil smoke cumulant threshold value, whether the current filter net needs to be replaced or washed or not is judged; and thus a user can be automatically and accurately reminded to replace or wash the filter net according to the real-time smoke concentration data and real-time oil smoke cumulant data on the filter net, so that the range hood is normally used by the user conveniently.

Description

Technical field [0001] The invention relates to the field of filter screen monitoring of a range hood, in particular to a device and method for monitoring the filter screen of a range hood. Background technique [0002] With the continuous improvement of living standards, people began to pay more and more attention to the air quality of the living environment, especially the kitchen. People gradually recognized the important role of range hoods on the air quality of the kitchen, so the range hood has become a necessary equipment for household kitchen appliances. [0003] Because the kitchen fume is relatively large, the fume in the kitchen will gradually cover the surface of the filter screen of the range hood when the range hood is started, which seriously affects the smoking effect of the range hood, so the filter screen needs to be replaced or cleaned frequently. [0004] However, most of the existing range hoods on the market do not have a monitoring system for the filter, and al...

Problems solved by technology

[0004] However, most of the existing range hoods on the market do not have a monitoring system for the filter, and almost all rely on the user's naked eyes to observe and judge the oil fume coverage on the surface of the filter, which is very inconvenient for the user to use the range hood normally and conveniently.

[0005] In response to the problem of oil fume monitoring on the filter of the range hood, some merchants have adopted a simple time accumulation method, that is, when the working time of the range hood has accumulated to the preset accumulation time, the range hood will remind the user to replace the filter or Cleaning the filter screen, this method of time accumulation is only a rough estimate of the time when the filter screen needs to be replaced or cleaned, but this method of oil fume monitoring is not accurate
