Range hood cleaning reminding system and method and variable-frequency range hood

Abstract

The invention provides a range hood cleaning reminding system and method and a variable-frequency range hood, and relates to the technical field of range hoods, the system comprises an oil screen, a fan and a smoke exhaust assembly which are connected in sequence, a variable-frequency control driving unit connected with the fan, and a user interaction module connected with the variable-frequency control driving unit. The user interaction module receives an exhaust gear instruction input by a user, the frequency conversion control driving unit obtains a first fan operation parameter, corresponding to an exhaust gear represented by the exhaust gear instruction, of the fan, and calculates a difference value between a preset second fan operation parameter and the first fan operation parameter; when the difference value meets a preset reminding threshold value, a reminding instruction is sent to a user interaction module, and after the user interaction module receives the reminding instruction, a cleaning reminder corresponding to the oil net or the smoke exhaust assembly is sent to a user. The problem of poor user experience caused by too early or too late reminding is avoided, the timeliness and accuracy of oil screen cleaning reminding are improved, and the use experience of a user is improved.

Description

technical field [0001] The present application relates to the technical field of range hoods, in particular to a range hood cleaning reminder system, method and frequency conversion range hood. Background technique [0002] Frequency conversion hoods have many advantages such as large air volume, strong wind pressure, low noise, and multiple gears. The technical characteristics of the variable frequency hood determine that when the flue is blocked or the oil net is blocked, the operating state of the hood will change significantly. [0003] In the prior art, when the range hood is reminded to clean the oil net, the reminder is usually based on the running time. For example, the cleaning time is estimated according to the operating time of the variable frequency range hood, and the user is reminded to clean the oil net every time the estimated cleaning time is reached. However, the judgment method based on the operating time can easily lead to cleaning the oil net too early...

Problems solved by technology

However, the judgment method based on the running time can easily lead to cleaning the oil screen too early and too late

If the reminder is too early, it will cause unnecessary cleaning, which is time-consuming and laborious; if the reminder is too late, the oil screen will be blocked seriously when the reminder is cleaned, which will lead to poor smoking effect, difficulty in cleaning the oil screen, and excessive noise. A series of problems such as poor user experience
