Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention more clear, the method, device and specific implementation of the fresh air fan system of the present invention will be described in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The method for controlling the replacement time of the filter screen of a new fan according to an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0049] S100, acquiring the air pollution level of the place where the fresh air machine is used in the current time period. Since the service life of the filter screen in the fresh air machine is directly related to the air quality during use, in this method, the air pollution level of the place where the fresh air machine is used is first obtained. The air po...

Abstract

The invention discloses a method and a device for controlling new fan filter screen use time as well as a new fan system. The method comprises the following steps: the air pollution degree of a new fan use location in the current time interval is acquired; the conversion factor of the new fan use time is acquired according to the air pollution degree; the conversion running time of the new fan in the current time interval is calculated according to the conversion factor; sum of the conversion running time of the new fan in the current time interval and the conversion already running time of the new fan is obtained, and the total conversion running time of the new fan is acquired; and when the total conversion running time is larger than or equal to filter screen replacement time, a new fan filter screen replacement alarm is given. Calculation of the filter screen use time is combined with the specific use environment of the new fan, the time is accurately calculated, waste caused by early replacement of the filter screen under good air quality condition is avoided, and the problem that use is influenced by poor air filter effect of the new fan due to the fact that the filter screen is not replaced in time in poor use environment is solved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a method and device for controlling the use time of a fresh air filter, and a fresh air system. Background technique [0002] When the fresh air fan is working, fresh air is introduced from the outside, filtered by the filter and then supplied to the room to improve the indoor air quality. The filter in the fresh air fan is a consumable and needs to be replaced regularly. [0003] The use time of the filter is related to the air quality, that is, the more dust there is outside, the more frequently the filter needs to be replaced. However, the usual practice is that there will be an approximate usage time in the instruction manual of the fresh fan, and the user can replace the filter of the fresh fan by himself according to the usage time. However, in reality, the air quality varies from place to place, even in the same place at different time periods (such as different seaso...
