(3) Control method of air outlet at tail end of fresh air
As shown in fig. 3, in this embodiment, on the basis of embodiments 1 and 2, a method for controlling an air outlet at a fresh air end is provided, which includes the following steps:
s001, presetting parameters;
s002, acquiring real-time parameters;
s003, judging the operating conditions of the filtering component 40 according to preset parameters and real-time parameters;
s004, if the first operation condition is met, controlling the filtering assembly 40 to form a single-layer filtering structure by the control device;
and S005, if the second operation condition is met, controlling the filtering component 40 to form a multi-layer filtering structure by the control device.
The control method of the fresh air end air outlet provided by the embodiment of the invention is based on the fresh air end air outlet, and the parameters are preset and the real-time parameters are collected firstly through the method, whether the first operation condition or the second operation condition is met is judged, so that the filter assembly 40 is deformed into the single-layer filter structure or the multi-layer filter structure, and through the method, dust with different contents can be dealt with at any time, thereby ensuring the cleanness of the fresh air end air outlet, improving the air quality, protecting the cleaning device 50 from being polluted by bacteria and mold, and preventing the odor from being generated due to mildew.
As an example, the control device controls the filtering assembly 40 to form a single-layer filtering structure, specifically: the control device controls the driving piece 42 to drive one of the filter units to be unfolded and drive the other filter units to be rolled up; the control device controls the filtering component 40 to form a multi-layer filtering structure, specifically: the control device controls the driving member 42 to drive at least two filter units to be fully unfolded.
It should be noted that the preset parameters and the real-time parameters may include at least one of a season parameter, an air volume numerical parameter, and a PM2.5 parameter, where the season parameter includes spring, summer, autumn, and winter. The present embodiment selectively operates according to regions and seasons. In northern areas, due to heating in winter, suspended particulate matters in air are more, the pollution is serious, the filtering component 40 forms a double-layer filtering structure to automatically operate, and whether the filtering component is started or not or whether the filtering component is manually started by a user is judged in the rest time according to the PM2.5 content; and in the southern area, whether the system is started or not is judged according to the PM2.5 content or the system is manually started by a user according to the requirement.
Preferably, the preset parameter is specifically a preset PM2.5 content a0, and the real-time parameter is specifically a real-time PM2.5 content a 1. Further, in the step of satisfying the first operating condition, specifically, a1 < a 0; in the step of satisfying the first operating condition, specifically, a 1. gtoreq.a 0. That is, when the PM2.5 content exceeds the set value, the filter assembly 40 needs to form a multi-layer filter structure, so as to better perform filtration, and when the PM2.5 content does not exceed the set value, the filter assembly 40 only needs to form a single-layer filter structure, so that the number of layers of the filter assembly 40 is small, and the filter assembly 40 is convenient to clean at a later stage.
After the step of the control device controlling the filter assembly 40 to form a single-layer filter structure, or after the step of the control device controlling the filter assembly 40 to form a multi-layer filter structure, the method further comprises the following steps:
presetting a wind resistance parameter b 0;
acquiring a real-time wind resistance parameter b 1;
if b1 is more than or equal to b0, continuing the filtering operation;
if b1 < b0 is satisfied, the cleaning device 50 is activated and the sterilizing device 10 is simultaneously activated.
Firstly, judging the operation conditions according to a preset program: when a1 is more than a0, the filter assembly 40 forms a single-layer filter structure, in particular; the stepping motor drives the second filtering unit 412 to rotate to be completely rolled up, so that the first filtering unit 411 forms a single-layer filtering structure; when a1 is more than or equal to a0, the filter assembly 40 forms a double-layer filter structure, which specifically comprises the following components: the stepping motor drives the second filtering unit 412 to rotate reversely to be completely unfolded, so that the first filtering unit 411 and the second filtering unit 412 form a double-layer filtering structure; and (3) the system operates, after a certain set time t is reached, the wind resistance sensor detects the pressure difference between two sides of the filter screen to measure the wind resistance, when b1 is more than b0, the cleaning device 50 is started to flush the filter element 41, and meanwhile, the sterilizing device 10 is started to perform sterilization treatment in the cleaning process. The sterilization apparatus 10 may be turned on or off as desired by the user. When b1 is more than or equal to b0, the filtration is continued.
Before the step of presetting the parameters, the method also comprises the step of starting up the air outlet at the tail end of the fresh air.
In addition, after the control method of the air outlet at the tail end of the fresh air is finished, whether the air outlet is shut down is judged, if yes, the air outlet is shut down, and if not, all the steps are repeated.
In this embodiment, the opening degree of the first regulating valve can be controlled by the control device to control the air output quantity of the micropores 31, so that the comfort level of the air output is improved, and the water supply quantity and the water discharge quantity of the water supply system and the water discharge system are also regulated by the opening degrees of the second regulating valve and the third regulating valve, so that water supply and water discharge are reasonable, and the suitable humidity and the humidity environment in the air outlet are ensured.
