Description
本发明属于空气净化技术领域，具体提供一种空气净化器滤网寿命判断方法和空气净化器。The invention belongs to the technical field of air purification, and specifically provides a method for judging the life of an air purifier filter screen and an air purifier.
空气净化器的核心部件是滤网和风扇，风扇通过转动将外部空气吸入净化器中，然后推动空气穿过滤网进行过滤，最后将过滤后的气体排出，从而实现空气净化。空气净化器的滤网具有一定的使用寿命，随着滤网的使用时间逐渐增长，滤网上积累的污染物会越来越多，污染物会逐渐阻塞滤网，因而滤网对空气的过滤净化效果也会逐渐变差，当滤网对空气的过滤效果达不到标准时，意味着滤网使用寿命已到，需要对空气净化器的滤网进行更换或清理。当滤网进行清洁时，虽然能够部分清除掉滤网的污浊物，以延长滤网的使用寿命，但是滤网终究是有使用寿命的。因此，本发明要解决的就是如何区分滤网是应该清洁还是更换的问题。The core components of the air purifier are the filter screen and the fan. The fan rotates to suck external air into the purifier, then push the air through the filter screen to filter, and finally exhaust the filtered air to achieve air purification. The filter screen of the air purifier has a certain service life. As the use time of the filter screen increases, more and more pollutants will accumulate on the filter screen, and the pollutants will gradually block the filter screen, so the filter screen filters and purifies the air. The effect will gradually deteriorate. When the filtering effect of the filter on the air is not up to the standard, it means that the service life of the filter has expired, and the filter of the air purifier needs to be replaced or cleaned. When the filter screen is cleaned, although the dirt of the filter screen can be partially removed to extend the service life of the filter screen, the filter screen has a service life after all. Therefore, the present invention is to solve the problem of how to distinguish whether the filter should be cleaned or replaced.

对滤网进行清洁虽然能够部分清除掉滤网的污浊物，延长滤网的使用寿命，但是滤网终究还是有使用寿命的，因此，本发明在对滤网进行清洁之后，通过检测滤网的过滤效率，即通过比较在相同风速下，净化后的滤网与干净的滤网将相同的空气PM2.5净化的设定值所需要的时间，进而判断滤网是否需要更换。这样一来，可以有效区分出滤网的状态，从而有效避免频繁更换滤网的问题。Although cleaning the filter screen can partially remove the dirt of the filter screen and prolong the service life of the filter screen, the filter screen has a service life after all.

为使本发明的实施例、技术方案和优点更加明显，下面将结合附图对本发明的技术方案进行清楚、完整的描述，显然，所述的实施例是本发明的一部分实施例，而不是全部实施例。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Examples. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
参照图1，图1是本发明空气净化器滤网寿命判断方法的主要流程图。如图1所示，本发明的空气净化器滤网寿命判断方法包括下列步骤：S110、在述滤网进行清洁之后，启动空气净化器并记录当前空气的PM2.5值；S120、记录空气净化器在当前风速下将当前空气的PM2.5值净化到设定值所用的时间T；S130、根据时间T判断滤网是否需要更换。具体地，在步骤S110中，启动空气净化器时，可以使空气净化器的风速为预设风速。也可以在在步骤S120中检测空气净化器的当前风速。Referring to Fig. 1, Fig. 1 is a main flow chart of the method for determining the life of the air purifier filter screen of the present invention. As shown in Figure 1, the method for determining the life of the air purifier filter of the present invention includes the following steps: S110, after the filter is cleaned, start the air purifier and record the current PM2.5 value of the air; S120, record the air purification The time T for the air filter to purify the current PM2.5 value of the air to the set value under the current wind speed; S130, determine whether the filter needs to be replaced according to the time T. Specifically, in step S110, when the air purifier is started, the wind speed of the air purifier may be set to a preset wind speed. It is also possible to detect the current wind speed of the air purifier in step S120.
作为一种示例，在步骤S130中，如果T－T
0＞预设时间，则判断滤网需要更换；否则判断滤网不需要更换。其中，T
0为在滤网未发生脏堵之前，空气净化器在相同风速下将当前空气的PM2.5值净化到设定值所需要的标准时间。具体而言，本发明通过比较在相同风速下(该风速可以是在启动空气净化器时的预设风速，也可以是在空气净化器启 动后检测的当前风速)，净化后的滤网与干净的滤网将相同的空气PM2.5净化的设定值所需要的时间。如果时间相同说明净化后的滤网很干净不需要更换；如果净化后的滤网所需要的时间T比T
0长，说明净化后的滤网扔存在一定的灰尘；如果净化后的滤网所需要的时间T超出T
0预设时间(例如4小时)，说明净化后的滤网扔存在较多的灰尘，此时说明滤网需要更换。需要说明的是，该预设时间可以由本领域技术人员根据试验确定，例如使用需要更换的滤网和干净的滤网在相同风速下将相同的PM2.5降低到设定值所需的时间进行比较，其差值可以作为预设时间。
As an example, in step S130, if T-T 0 > preset time, it is determined that the filter screen needs to be replaced; otherwise, it is determined that the filter screen does not need to be replaced. Among them, T 0 is the standard time required for the air purifier to purify the current PM2.5 value of the air to the set value under the same wind speed before the filter screen is dirty. Specifically, the present invention compares the purified filter with the cleaned filter under the same wind speed (the wind speed can be the preset wind speed when the air purifier is started, or the current wind speed detected after the air purifier is started). The time required for the filter to purify the same air with the set value of PM2.5. If the time is the same, it means that the purified filter is very clean and does not need to be replaced; if the purified filter requires a longer time T than T 0 , it means that there is a certain amount of dust in the purified filter; if the purified filter is The required time T exceeds the preset time T 0 (for example, 4 hours), indicating that there is more dust in the purified filter, and at this time, it indicates that the filter needs to be replaced. It should be noted that the preset time can be determined by those skilled in the art according to experiments, for example, the time required to reduce the same PM2.5 to the set value under the same wind speed with a filter that needs to be replaced and a clean filter For comparison, the difference can be used as the preset time.
上述时间T
0还可以按照如下方式确定：在滤网未发生脏堵之前，获取m次空气净化器在相同风速下将当前空气的PM2.5值净化到设定值时所需的时间T
1、T
2…T
m；T
0＝T
1+T
2+…+T
m/m；m为大于1的整数。此时T
0为空气净化器在相同风速下将当前空气的PM2.5值净化到设定值所需要的平均时间，这样可以进一步增加判断滤网是否需要更换的准确性。
The above-mentioned time T 0 can also be determined as follows: before the filter screen is dirty, obtain the time T 1 required for the air purifier to purify the current PM2.5 value of the air to the set value at the same wind speed for m times , T 2 …T m ; T 0 =T 1 +T 2 +…+T m /m; m is an integer greater than 1. At this time, T 0 is the average time required for the air purifier to purify the current PM2.5 value of the air to the set value under the same wind speed, which can further increase the accuracy of judging whether the filter needs to be replaced.
作为另一中示例，在步骤S120中可以重复记录n次空气净化器在当前风速下将当前空气的PM2.5值净化到设定值所用的时间T

n；n为大于1的整数。然后，在步骤S130中，比较每次所用的时间T

0，说明滤网需要更换。该实施例中，在判断滤网是否需要进行更换时，可以极大地增加判断结果的准确性，避免了因一次偶然性带来的误判。同理，该实施例中，T
0可以为在滤网未发生脏堵之前，空气净化器在相同风速下将当前空气的PM2.5值净化到设定值所需要的标准时间。此外，T
0还可以按照如下方式确定：在滤网未发生脏堵之前，获取m次空气净化器在相同风速下将当前空气的PM2.5值净化到设定值时所需的时间T

As another example in, in step S120 may be repeatedly recorded n times in the air purifier PM2.5 purge the current wind speed value to the set value of the air current used time T 1, T 2 ... T n ; n is greater than An integer of 1. Then, in step S130, compare the time T n and T 0 used each time; when the number that satisfies T n- T 0 > the preset time is greater than or equal to n/2, it is judged that the filter needs to be replaced; otherwise, it is judged No need to replace. In other words, if the air purifier is working multiple times, if more than half of the time exceeds T 0 , it means that the filter needs to be replaced. In this embodiment, when judging whether the filter screen needs to be replaced, the accuracy of the judgment result can be greatly increased, and a misjudgment caused by an accident can be avoided. Similarly, in this embodiment, T 0 may be the standard time required for the air purifier to purify the current PM2.5 value of the air to the set value at the same wind speed before the filter screen is dirty. In addition, T 0 can also be determined as follows: Before the filter screen is dirty, obtain the time T 1 required for the air purifier to purify the current PM2.5 value of the air to the set value under the same wind speed. , T 2 …T m ; T 0 =T 1 +T 2 +…+T m /m; m is an integer greater than 1. At this time, T 0 is the average time required for the air purifier to purify the current PM2.5 value of the air to the set value under the same wind speed, which can further increase the accuracy of judging whether the filter needs to be replaced.
