For example, at a point of time t0To a time point t4In the time interval of (2), the actual total amount of oil smoke flowing through the filter screen is
Step 3, presetting a soot accumulation threshold value for the filter screen, and judging whether the current filter screen needs to be replaced or cleaned according to the actual soot total amount flowing through the filter screen and the preset soot accumulation threshold value: wherein, the preset oil smoke accumulation threshold value for the filter screen is marked as M0：

In order to match the replacement need or the filter screen cleaning need of the user to the filter screen, the range hood filter screen monitoring method further comprises the following steps: recording the oil smoke accumulation amount on the corresponding filter screen when the filter screen is replaced by a user each time to obtain an oil smoke accumulation amount threshold value matched with the filter screen replacement habit of the user; or,
and recording the oil smoke accumulation amount on the corresponding filter screen when the user cleans the filter screen each time to obtain an oil smoke accumulation amount threshold value matched with the habit of the user for cleaning the filter screen.
For example, if the preset number of times for replacing the filter screen by the user is set to three times, in the three filter screen replacing behaviors of the user, the corresponding oil smoke accumulation amounts on the filter screens are respectively M when the user replaces the filter screen each time1、M2And M3Then according to the corresponding oil smoke accumulation amount M of the three times1、M2And M3Obtaining the oil smoke accumulation threshold value matched with the filter screen replacement habit of a user;

wherein M isReplacement, rThe accumulated amount of the oil smoke on the corresponding filter screen when the filter screen is cleaned for the R time by the user is shown, and R shows the preset times when the filter screen is cleaned for the user.
For example, assuming that the preset number of times for the user to clean the filter screen is four, the threshold of the accumulated amount of lampblack matching the habit of the user to clean the filter screen is set
In addition, the method for monitoring the filter screen of the range hood in the embodiment can further comprise the following steps: after a prompt that the current filter screen needs to be replaced or cleaned is sent, the actual total oil smoke amount of the flow filter screen is cleared, so that the accuracy of filter screen monitoring is guaranteed.

Therefore, the user can be helped to know the accumulated amount of the oil smoke on the filter screen more simply and directly by setting the oil smoke coverage degree. For example, the oil smoke coverage degree value on the filter screen is in linear correlation or logarithmic correlation or exponential correlation with the accumulated oil smoke amount on the filter screen.

(1) assuming that the oil smoke coverage degree value a on the filter screen and the oil smoke accumulation amount M on the filter screen are in a linear correlation relationship, at this time: a ═ f (M) ═ w · M + b1(ii) a Wherein, w and b1Are all preset constants;
(2) assuming that the oil smoke coverage degree value a on the filter screen and the oil smoke accumulation amount M on the filter screen are in a logarithmic correlation relationship, at this time: a ═ f (m) ═ logv(M)+b2(ii) a Wherein v and b2Are all preset constants;
(3) assuming that the oil smoke coverage degree value a on the filter screen and the oil smoke accumulation amount M on the filter screen are in an exponential correlation relationship, at this time: a ═ f (M) ═ x.M'1+x·(1+p)·M'2+x·(1+p)2·M'3+…+x·(1+p)m-1·M'm(ii) a Wherein x and p are preset constants, M'1、M'2、M'3、…、M'mIs the accumulated amount of the oil smoke on the filter screen corresponding to each time point.
