Abstract
The invention relates to a method for real-time monitoring the pollution level of a filter layer of an air purification machine, comprising a detection method of air quality. The method is characterized in that air quality sensors are arranged at the air inlet end and the air outlet end of the filter layer and used for detecting the air quality at the two sides of the filter layer; and an operation circuit judges the pollution level of the filter layer according to air quality signals detected by the two air quality sensors. When the filter layer is severely polluted so that the purification effect is poor, an alarm signal can be sent out to remind a user of timely changing or washing the filter layer, thereby ensuring the use effect of the air purification machine.
Description
Technical field
The present invention relates to the technology of a kind of air cleaner of household appliance technical field.
Background technology
Air cleaner includes blower fan and filter course, and filter course can adopt one or more of filter types such as physics, chemistry, biology, and blower fan makes air pass through from filter course, realizes the filtration, purification purpose by filter course.Because the removing pollutant effect can descend, need change cleaning after filter course work a period of time, prior art is not effectively monitored the pollution level of filter course, gives user prompt when the clean-up effect variation.
Summary of the invention
The object of the invention is to disclose a kind of method that can monitor the filter course pollution level in real time.
The present invention includes the detection method of air quality, it is characterized in that in the inlet end and the outlet side of filter course air mass sensor being installed respectively, be used to detect the air quality of filter course both sides, again by computing circuit according to two detected air mass signals of air mass sensor, judge the pollution level of filter course, and make alarm by warning device.The decision method of described computing circuit is poor according to two air quality values, differentiates the pollution level of filter course, when the difference of two air quality values during less than setting value, judges that filter course pollutes and surpasses setting value, drives warning device and sends alarm.
The present invention detects through the air quality before and after the filtering layer by convection current, and judge the pollution level of filter course according to the difference of two air quality values, when both value too near the time, judge that then the filter course pollution level causes clean-up effect poor more greatly, so alarm signal of sending, call user's attention is in time changed or is cleaned, and guarantees the result of use of air cleaner.
Description of drawings
Accompanying drawing is a fundamental diagram of the present invention.
The specific embodiment
Below with reference to the accompanying drawings, embodiments of the invention are described.
Among the figure, KQ1 and KQ2 are two air mass sensors, be installed in inlet end and the both sides, outlet side of the filter course G of air cleaner respectively, be used for detecting respectively the air quality of flowing through before and after the filter course G, the output valve of air borne sensor KQ1 and KQ2 was also high when air pollution was high.The air quality value of two sensor detections is delivered to two inputs of computing circuit L, the pollution level of filter course is judged according to two air quality values by computing circuit L.
At the filter course clean-up effect just often, the air quality of filter course outlet side can be significantly better than the air quality of inlet end, also promptly the missionary society of two air quality values is greater than a certain setting value, so computing circuit L judges that the filter course pollution level is little, it is not luminous with luminous tube LED to report to the police.And when filter course long-term work institute is contaminated when surpassing to a certain degree, its clean-up effect descends, make the air quality of filter course outlet side and inlet end the same substantially, the output signal of KQ1 and KQ2 is equal substantially, and when the difference of two air mass signals during less than setting value, it is big that computing circuit L is judged to be the filter course pollution level, it is luminous to drive luminous tube LED, the filter course of prompting user air cleaner has polluted bigger, needs to change or cleaned, and reaches purpose of the present invention.
Claims (2)
1. real-time method of monitoring air cleaner filter course pollution level, the detection method that comprises air quality, it is characterized in that in the inlet end and the outlet side of filter course air mass sensor being installed respectively, be used to detect the air quality of filter course both sides, again by computing circuit according to two detected air mass signals of air mass sensor, judge the pollution level of filter course, and make alarm by warning device.
2. the method for a kind of real-time monitoring air cleaner filter course pollution level according to claim 1, the decision method that it is characterized in that described computing circuit, be poor according to two air quality values, differentiate the pollution level of filter course, when the difference of two air quality values during, judge that filter course pollutes and surpass setting value less than setting value.
