Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] figure 1 It is a flow chart of a dust sensor zeroing method for a purification device provided by an embodiment of the present invention. Such as figure 1 As shown, the present invention provides a dust sensor zeroing method, which method includes: controlling the operation of the purification device (step S11); recording a plurality of air dust concentrations detected by the dust sensor and corresponding values ​​of the plurality of air dust concentrations. Purify time (step S12); Judging whether a plurality of air dust concentrations detected meet requirements (step S13); whether the corresponding purification time is greater than the theoretical com...

Abstract

The invention relates to the optimization of electric appliances and discloses a dust sensor zero-adjusting method for a purification device. The method comprises the following steps: controlling the purification device to work, and recording a plurality of air dust concentrations detected by the dust sensor and purification time corresponding to the plurality of air dust concentrations; judging whether the detected air dust concentration meets requirements or not; when the detected air dust concentration meets the requirements, judging whether the purification time corresponding to one of the air dust concentration meeting the requirements is longer than the theoretical complete purification time or not; when the purification time corresponding to one of the air dust concentrations meeting the requirements is longer than the theoretical complete purification time, setting the air dust concentration corresponding to the purification time more than the theoretical complete purification as a zero point. By the method, the dust sensor can be subjected to zero adjustment accurately and automatically.

Description

technical field [0001] The present invention relates to electrical appliance optimization, in particular to a dust sensor zeroing method and device for a purification device and a purification device. Background technique [0002] Dust sensors are almost the sensors that must be equipped with current purification devices, such as purifiers, fresh air systems, and other household appliances with purification functions. The dust sensor is used to monitor the dust concentration in the air environment. Usually, the zero point of the sensor will drift after being used for a period of time. The amount of zero point drift will vary with the time and place of use, which will affect the accuracy of the measurement results. The longer the sensor is used and the harsher the environment, the more obvious the zero point drift will be. Generally, the zero adjustment of the dust sensor cannot be performed at the user's home, and it is very troublesome to return to the manufacturer. Cont...
