Effective utilization time integrating method and device for filter screen in air purifier

Abstract

The invention provides an effective utilization time integrating method and a device for a filter screen in an air purifier. The effective utilization time integrating method comprises determining a current rotation speed of a fan in the air purifier according to air cleanliness to obtain an integrating weight ratio corresponding to the current rotation speed; calculating sustained utilization time of the fan when the fan rotation speed is the current rotation speed; and multiplying the sustained utilization time by the integrating weight ratio to obtain the effective utilization time. According to the method, the effective utilization time T of the filter screen can be obtained, so that the filter screen can be used furthest, and cost and time resources are saved. The method has the advantages that effects of fan speeds on the utilization time of the filter screen is considered, users are reminded reasonably to change the filter screen, and multiple defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to a method and device for calculating the effective use time of a filter screen in an air purifier. Background technique [0002] An air purifier generally includes a filter, a fan, a processor, and an air sensor that senses air cleanliness. The working principle of the air purifier is as follows: the sensor senses the air cleanliness and transmits a corresponding signal to the processor of the air purifier; The signal calculates the fan speed that can achieve the best filtering effect, and generates an electric control signal to make the fan generate a corresponding speed; the fan rotates and blows the air in the atmosphere to the filter, and the air is filtered by the filter to send out clean air. new air. Since the faster the fan speed, the more dust per unit area passing through the filter, and the more dust attached to the filter per unit time, so the fast and slow fan speed can ...

AI Technical Summary

Problems solved by technology

[0004] But the method of prior art can not utilize filter screen to the greatest extent, has caused the waste of certain cost resource

As mentioned above, the air cleanliness will affect the speed of the fan. Assuming that the preset service life of the filter is 9 months, the speed of the fan will be faster when the air cleanliness is relatively low. At this time, the filter may It cannot be used for 9 months. For the same reason, the speed of the fan will be slower when the air cleanliness is relatively high. At this time, the filter may be able to be used for 10 months or even longer, so the existing technology cannot maximize The use of filter nets has caused a certain waste of cost and resources
