Description
Technical Field
The invention relates to the field of air purifiers, in particular to a filter element service life reminding method, a filter element service life reminding system and an air purifier.
Background
Along with the gradual improvement of people's degree of concern to pollutant in the indoor air, people also constantly increase to air purifier's demand degree. As simple effectual air purification equipment, air purifier can make quick effective filtration to common fixed pollutant and the gaseous pollutant in the room air, realizes air purification's effect. In an air purifier, a filter is a key component that determines the purifying effect against pollutants in the air. However, the effective purifying function of the filter element is life-span, and once the life-span is exceeded, the purifying effect of the filter element is very low or even lost. Therefore, how to realize the accurate detection of the life of the filter element in the air purifier and remind the replacement of the filter element in the air purifier in time becomes a technical problem which must be solved in the industry.
Currently, many manufacturers detect the accumulated service time of the filter element by timing the operating time of the filter element to determine whether the filter element has reached its predetermined life. Once the accumulated working time of the filter element is detected to reach the preset service life, the air purifier gives an alarm prompt. However, since the service life of the filter element is greatly influenced by the service environment and the habit of the user, and the service life of the filter element is not in a linear relationship, two error results can occur when the service life of the filter element is evaluated in a timing manner:
the first condition is that although the accumulated filtering time of the filtering element is longer, the so-called preset service life is reached, the filtering effect still meets the qualified requirement, at the moment, the replacement or cleaning of the filtering element is prompted only by the accumulated working time, obviously inaccurate, economic waste can be caused by frequent replacement of the filtering element, and the removal rate is reduced by frequent cleaning of the filtering element due to invisible damage of the filtering element;
the second situation is that the removal rate of the filter element is not satisfactory as long as the filter element has not reached its preset life, and if the service life of the filter element is determined only by the accumulated working time, the filter element is obviously inaccurate, and the air purifier is caused to operate under the condition that the removal rate is low or the filter effect is not available for a long time, thereby affecting the air purification efficiency and causing the waste of electric power.
Of course, there are also many manufacturers who provide different detection reminding methods for the life of the filter element in the air purifier. The Chinese patent application CN107297109A discloses an air purification device and a filter element service life reminding system and a reminding method thereof, wherein two detectors are arranged to detect the windward side pollutant concentration of a filter element and the air outlet side pollutant concentration of the filter element respectively, then the real-time removal rate of the filter element is calculated according to the windward side pollutant concentration and the air outlet side pollutant concentration of the filter element, the current pollutant purification amount is calculated according to the real-time removal rate, the air volume of the current wind gear, the current starting time and the windward side pollutant concentration, the current pollutant purification amount and the historical pollutant purification amount are accumulated to obtain the total pollutant purification amount, and then reminding is carried out according to the total pollutant purification amount so as to remind a user to replace or clean the filter element more accurately and avoid secondary pollution.
However, the filter life reminding method in the patent application CN107297109A has some problems:
firstly, the method accumulates the purification amount of the pollutants of the filter element all the time, and once the accumulated purification amount of the pollutants exceeds a preset reminding value of the total purification amount of the pollutants, the service life of the filter element is determined to be required to be replaced or cleaned currently. Obviously, the method does not consider the use environment factors of the air purifier, if the air purifier is newly bought and is used only a few times, only because the air environment in one use has more pollutants, and as a result, the accumulated pollutant purification amount corresponding to the time exceeds the preset total pollutant purification amount, and then the user is reminded to replace the filter element, so that the prompt of replacing the filter element is obviously not in accordance with the actual situation, the cost of the user is increased, and the reliability of the performance of the air purifier for the user is reduced;
secondly, the method adopts the steps of obtaining the total purifying amount of the pollutants, and then reminding according to the total purifying amount of the pollutants so as to remind a user to replace or clean the filter element. However, the method does not accurately and definitely give a prompt for advising a user to replace the filter element under any condition and advising the user to clean the filter element under any condition, so that the user cannot accurately know whether the filter element should be replaced or the filter element should be cleaned even if the user receives the prompt, the trust level of the user on the service life prompt of the air purifier must be reduced, and the using satisfaction level of the user on the air purifier is greatly reduced.
