Detailed Description
In order to make the embodiments, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The invention provides a self-cleaning control method of an air conditioner, which aims to more accurately control the self-cleaning of the air conditioner. Referring to fig. 1, fig. 1 is a main flowchart of a self-cleaning control method of an air conditioner of the present invention. As shown in fig. 1, the self-cleaning control method of the air conditioner of the present invention includes the following steps: s110, detecting the dust concentration P on a heat exchanger of the indoor unit in the process of operating the air conditioner in a standard self-cleaning mode; s120, detecting the current indoor air humidity T; and S130, selectively adjusting the frosting time and/or the defrosting time of the standard self-cleaning mode according to the dust concentration P and the indoor air humidity T.
As an example, in step S110, the step of detecting the dust concentration P on the indoor unit heat exchanger includes: blowing air to a heat exchanger of the indoor unit by using an air blowing device; the concentration of dust blown up by the blowing device is detected by a dust sensor. Specifically, the blowing device can be a fan of the indoor unit, and the fan is only required to be reversely rotated to blow to a heat exchanger of the indoor unit; the air blowing device can also be a special fan which is independently arranged on the indoor unit, and the special fan is used for blowing air to the heat exchanger of the indoor unit.
As can be understood by those skilled in the art, when the heat exchanger of the indoor unit is dirty, the intensity of self-cleaning is required to be high, that is, frost needs to be thicker; when the heat exchanger of the indoor unit is cleaner, the self-cleaning needs to be frosted slightly thinner. However, in the self-cleaning operation of the conventional air conditioner, the frosting time and the defrosting time are both fixed and unchanged, so in order to control the self-cleaning of the air conditioner more precisely, in step S130, the frosting time and/or the defrosting time in the self-cleaning mode may be specifically adjusted as follows.
The first situation is as follows: and when the first preset threshold value is less than the second preset threshold value and the second preset humidity value is less than the T and less than the first preset humidity value, executing a standard self-cleaning mode of the air conditioner. Specifically, the first preset threshold and the second preset threshold may be obtained through experiments by those skilled in the art, and when the dust concentration P is between the first preset threshold and the second preset threshold, it is determined that the heat exchanger of the indoor unit is in a normal dirty state. The second preset humidity value and the first preset humidity value may also be obtained through experiments by those skilled in the art, and when the indoor air humidity T is between the second preset humidity value and the first preset humidity value, it is determined that the current indoor humidity is in a general humidity state. In this case, a standard self-cleaning mode of the air conditioner is performed, i.e., the frosting/defrosting time in the self-cleaning mode is not increased or decreased.
Case two: and when the first preset threshold value is less than the second preset threshold value and T is more than or equal to the first preset humidity value, reducing the frosting time of the standard self-cleaning mode by the first preset time. Specifically, as mentioned above, when the dust concentration P is between the first preset threshold and the second preset threshold, it is determined that the heat exchanger of the indoor unit is in a generally dirty state; when the indoor air humidity T is higher than the first preset humidity value, it may be determined that the current indoor air humidity is in a humid state. In this case, the frosting time of the standard self-cleaning mode is reduced by the first preset time, and the defrosting time is maintained. The first predetermined time may be obtained by a person skilled in the art by experimentation, for example the first predetermined time may be 1 minute, or any time between 0.5 and 1.5 minutes.
Case three: and when the first preset threshold value is less than the second preset threshold value and the T is less than or equal to the second preset humidity value, increasing the frosting time of the standard self-cleaning mode by the second preset time. Specifically, as mentioned above, when the dust concentration P is between the first preset threshold and the second preset threshold, it is determined that the heat exchanger of the indoor unit is in a generally dirty state; when the indoor air humidity T is lower than the second preset humidity value, it may be judged that the current indoor air humidity is in a dry state. In this case, the frosting time of the standard self-cleaning mode is increased by a second preset time, and the frosting time is maintained. The second predetermined time may be obtained by a person skilled in the art by experimentation, for example the second predetermined time may be 5 minutes, or any time between 4.5 and 5.5 minutes.
Case four: and when the P is larger than or equal to a second preset threshold value and the second preset humidity value is smaller than T and smaller than the first preset humidity value, increasing the frosting time of the standard self-cleaning mode by second preset time and increasing the frosting time of the standard self-cleaning mode by first preset time. Specifically, when the dust concentration P is higher than a second preset threshold, it can be determined that the heat exchanger of the indoor unit is in a severe dirty state; and when the indoor air humidity T is between the second preset humidity value and the first preset humidity value, judging that the current indoor humidity is in a common humidity state. In this case, the frosting time of the standard self-cleaning mode is increased by a second preset time, and the frosting time of the standard self-cleaning mode is increased by a first preset time. The first preset time and the second preset time can be obtained by a person skilled in the art according to tests, for example, the first preset time can be 1 minute or any time between 0.5 and 1.5 minutes, and the second preset time can be 5 minutes or any time between 4.5 and 5.5 minutes.
Case five: and when P is larger than or equal to a second preset threshold value and T is larger than or equal to a first preset humidity value, increasing the defrosting time of the standard self-cleaning mode by a first preset time. Specifically, when the dust concentration P is higher than a second preset threshold, it can be determined that the heat exchanger of the indoor unit is in a severe dirty state; when the indoor air humidity T is higher than the first preset humidity value, it may be determined that the current indoor air humidity is in a humid state. In this case, the defrosting time of the standard self-cleaning mode is increased by a first preset time, and the frosting time is maintained. The first predetermined time may be obtained by a person skilled in the art by experimentation, for example the first predetermined time may be 1 minute, or any time between 0.5 and 1.5 minutes.
Case six: and when the P is larger than or equal to a second preset threshold value and the T is smaller than or equal to a second preset humidity value, increasing the frosting time of the standard self-cleaning mode by a third preset time, and increasing the frosting time of the standard self-cleaning mode by a first preset time. Specifically, when the dust concentration P is higher than a second preset threshold, it can be determined that the heat exchanger of the indoor unit is in a severe dirty state; when the indoor air humidity T is lower than the second preset humidity value, it may be judged that the current indoor air humidity is in a dry state. In this case, the frosting time of the standard self-cleaning mode is increased by a third preset time, and the defrosting time of the standard self-cleaning mode is increased by the first preset time. The third predetermined time and the first predetermined time may be obtained by a person skilled in the art according to experiments, for example, the third predetermined time may be 10 minutes, or any time between 9 and 11 minutes, and the first predetermined time may be 1 minute, or any time between 0.5 and 1.5 minutes.
It should be noted again that, the first preset threshold and the second preset threshold may be obtained by a person skilled in the art through a test, specifically, a maximum value of the dust concentration when the heat exchanger of the indoor unit is in a general dirty state is obtained through test data, and when the dust concentration is higher than the maximum value, it is determined that the heat exchanger of the indoor unit is in a serious dirty state. Similarly, the first preset humidity value and the second preset humidity value may also be obtained by a person skilled in the art through a test, specifically, an interval range when the indoor air humidity is at the ordinary humidity is obtained through test data, after the interval range is determined, if the indoor air humidity is higher than an upper limit of the interval range, it is indicated that the indoor air humidity is in a wet state, and if the indoor air humidity is lower than a lower limit of the interval range, it is indicated that the indoor air humidity is in a dry state. In addition, the first preset time, the second preset time and the third preset time can also be obtained by the skilled person through experiments.
The invention also provides an air conditioner, which comprises a controller, wherein the controller is configured to execute the self-cleaning control method of the air conditioner.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
