As time goes by, the dust accumulation on the indoor unit of the air conditioner will gradually increase. When the dust accumulation reaches a certain level, a large number of bacteria will breed, especially when the indoor air flows through the room. The air conditioner needs to be cleaned in time because it will carry a lot of dust and bacteria when it is running.
现在空调器多采用自清洁的方式,即通过控制室内机的运行,使得蒸发器先结霜、后化霜,利用化霜对蒸发器进行清洁。现有空调器在运行自清洁的过程中,结霜时间和化霜时间均是固定不变的,该固定不变的时间一般是在较为理想的、特定的试验工况下所确定的值。但是在空调器实际运行的过程中,其实际运行工况与理想的、特定的试验工况可能存在一定差异,这就导致空调器在按照运行现有自清洁程序时容易出现控制不够精确的问题,如结霜时间过短导致清洁不充分等。Now air conditioners mostly adopt a self-cleaning method, that is, by controlling the operation of the indoor unit, the evaporator is frosted first and then defrosted, and the evaporator is cleaned by defrosting. During the self-cleaning process of the existing air conditioner, both the frosting time and the defrosting time are fixed, and the fixed time is generally a value determined under ideal and specific test conditions. However, in the actual operation of the air conditioner, there may be some differences between the actual operating conditions and the ideal and specific test conditions. This leads to the problem of insufficient control accuracy when the air conditioner runs in accordance with the existing self-cleaning procedures. , Such as insufficient cleaning due to too short frosting time.
因此,本领域提出了一种新的空调器自清洁控制方法来解决上述问题。Therefore, a new air conditioner self-cleaning control method is proposed in the art to solve the above-mentioned problems.

本领域技术人员能够理解的是,当室内机的换热器较脏时,则需要自清洁的强度高,也就是需要结霜更厚;当室内机的换热器较干净时,自清洁需要结霜稍薄一些。而现有的空调器在运行自清洁的过程中,结霜时间和化霜时间均是固定不变的,因此为了更加精确地控制空调器的自清洁,在步骤S130中,具体可以按照以下情形调整在自清洁模式下的结霜时间和/或化霜时间。Those skilled in the art can understand that when the heat exchanger of the indoor unit is dirty, the intensity of self-cleaning needs to be high, that is, thicker frost is required; when the heat exchanger of the indoor unit is relatively clean, self-cleaning needs The frost is slightly thinner.

需要再次说明的是,上述中的第一预设风量值和第二预设风量值可以由本领域技术人员通过试验的方式得到,具体为通过试验数据获取室内机的换热器处于一般污浊状态时的出风风量的区间范围,以及 室内机的换热器处于严重污染状态时的出风风量的最高值(该最高值即在室内机的换热器处于一般污浊状态时的出风风量的区间范围的最低值)。同理,第一预设湿度值和第二预设湿度值也可以由本领域技术人员通过试验的方式得到,具体为通过试验数据获取室内空气湿度处于一般湿度时的区间范围,在确定该区间范围之后,室内空气湿度高于该区间范围的上限,则说明室内空气湿度为潮湿状态,室内空气湿度低于该区间范围的下限,则说明室内空气湿度为干燥状态。另外,第一预设时间、第二预设时间和第三预设时间也可以由本领域技术人员通过试验的方式获得最佳值。It needs to be explained again that the first preset air volume value and the second preset air volume value mentioned above can be obtained by those skilled in the art through experiments, specifically when the heat exchanger of the indoor unit is in a general dirty state obtained through experimental data The range of the air volume of the indoor unit, and the highest value of the air volume when the heat exchanger of the indoor unit is in a severely polluted state (the highest value is the range of the air volume when the heat exchanger of the indoor unit is in a general dirty state The lowest value of the range). In the same way, the first preset humidity value and the second preset humidity value can also be obtained by those skilled in the art through experiments. Specifically, the interval range when the indoor air humidity is at the general humidity is obtained through test data, and the interval range is determined After that, if the indoor air humidity is higher than the upper limit of the interval range, it means that the indoor air humidity is in a humid state; if the indoor air humidity is lower than the lower limit of the interval range, it means that the indoor air humidity is dry. In addition, the first preset time, the second preset time, and the third preset time can also be obtained by those skilled in the art through experiments.
在一种更具体地实施方式中,在执行步骤S110之前,本发明的空气自清洁控制方法首先执行以下步骤:实时检测室内机出风口的出风风量;当出风风量满足预设条件时,使空调器运行标准自清洁模式。可以利用安装在室内机出风口位置的风量传感器检测出风风量。In a more specific implementation, before performing step S110, the air self-cleaning control method of the present invention first performs the following steps: real-time detection of the air volume of the air outlet of the indoor unit; when the air volume meets the preset condition, Make the air conditioner run the standard self-cleaning mode. The air volume can be detected by the air volume sensor installed at the air outlet of the indoor unit.
作为示例,该预设条件可以是:出风风量低于第一设定值。具体而言,空调器在正常运行的情况下(室内机的换热器未被堵塞),室内风机的转速一定时,室内机出风口的出风风量也是一定的,而换热器堵塞之后,出风风量也会随之减小。这种情况下,我们可以设定一个第一设定值,该第一设定值可以由本领域技术人员通过试验方式获得,当出风风量低于该第一设定值时,可以判断室内机的换热器出现灰尘较多的现象,即需要进行清洁。As an example, the preset condition may be: the outlet air volume is lower than the first set value. Specifically, when the air conditioner is in normal operation (the heat exchanger of the indoor unit is not blocked), when the speed of the indoor fan is constant, the air volume of the air outlet of the indoor unit is also constant, and after the heat exchanger is blocked, The air volume will also decrease accordingly. In this case, we can set a first set value, which can be obtained by those skilled in the art through experiments. When the air output is lower than the first set value, it can be judged that the indoor unit The heat exchanger is dusty and needs to be cleaned.
作为另一种示例,该预设条件也可以是:每隔设定时间检测一次室内机出风口的出风风量的平均值,并且平均值低于第二设定值。如上所述,为了更精确地判断空调器进入自清洁的时机,还可以通过采集多个出风风量,计算其平均值,通过比较平均值来更精确地判断空调器进入自清洁的时机。该第二设定值可以由本领域技术人员通过试验方式获得。As another example, the preset condition may also be: detecting the average value of the air output from the air outlet of the indoor unit every set time, and the average value is lower than the second set value. As described above, in order to more accurately determine the timing of the air conditioner entering the self-cleaning, it is also possible to collect multiple air volumes, calculate the average value, and compare the average values to more accurately determine the timing of the air conditioner entering the self-cleaning. The second set value can be obtained by those skilled in the art through experiments.
作为另一种示例,该预设条件还可以是:检测室内机出风口在风机处于不同转速下的出风风量L 1,计算出风风量L 1与对应转速下的L 0的差值△L,并且△L高于第三设定值;其中,△L=L 0-L 1,L 0为风机在不同转速下设定的标准风量值。具体而言,L 0为风机在不同转速下设定的标准风量值,也即在室内机的换热器没有灰尘的情形下,室内风机在不同转速下对应的出风量。通过将当前出风风量L 1与对应的标准风 量值L 0比较,可以准确地判断出室内机换热器上灰尘的程度,进而更准确地判断是否使空调器进入自清洁。 As another example, the preset condition may also be: detecting the air volume L 1 of the air outlet of the indoor unit when the fan is at different speeds, and calculating the difference △L between the air volume L 1 and L 0 at the corresponding speed. , And △L is higher than the third setting value; among them, △L=L 0 -L 1 , L 0 is the standard air volume value set by the fan at different speeds. Specifically, L 0 is the standard air volume value set by the fan at different speeds, that is, when the heat exchanger of the indoor unit has no dust, the corresponding air volume of the indoor fan at different speeds. By comparing the current air volume L 1 with the corresponding standard air volume value L 0 , it is possible to accurately determine the degree of dust on the indoor unit heat exchanger, and then to more accurately determine whether to make the air conditioner enter self-cleaning.
至此,已经结合附图所示的优选实施方式描述了本发明的技术方案,但是,本领域技术人员容易理解的是,本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings.
