Air conditioner self-cleaning humidification control method

technical field

The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning and humidifying control method for an air conditioner.

Background technique

The air conditioner is a device that can cool/heat indoors. Over time, the dust accumulation on the indoor unit of the air conditioner will gradually increase. After the accumulation of dust to a certain extent, a large number of bacteria will breed, especially when the indoor air flows through the room. When the machine is on, it will carry a lot of dust and bacteria, so it is necessary to clean the air conditioner in time. Nowadays, air conditioners mostly adopt the self-cleaning method, that is, by controlling the operation of the indoor unit, the evaporator is first frosted and then defrosted, and the evaporator is cleaned by defrosting.

When the air conditioner performs self-cleaning, the effect of self-cleaning has a great relationship with the intensity of frosting, and the intensity of frosting has a great relationship with the indoor humidity. When the indoor air quality is poor, if the moisture in the indoor air is used for frosting, it will also bring in the dust in the air, which will affect the self-cleaning effect. Moreover, too much humidification will also cause the self-cleaning frost to be too thick, which may cause certain damage to the machine.

Detailed ways

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 described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are a part of the embodiments of the present invention, not all of them. Example. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.

The air conditioner of the present invention comprises an indoor unit, a water storage chamber and a humidification module arranged in the indoor unit, and the humidification module can atomize the water in the water storage chamber to humidify the indoor air. In addition, the air conditioner of the present invention performs self-cleaning on the indoor unit by means of first frosting and then defrosting.

Referring to FIG. 1 , FIG. 1 is a main flow chart of a self-cleaning and humidifying control method for an air conditioner of the present invention. As shown in FIG. 1 , the air conditioner self-cleaning and humidifying control method of the present invention includes the following steps: S110. During the self-cleaning process, start the humidification module and make the operation frequency of the humidification module be the first preset operation frequency; S120, Acquire the real-time temperature of the indoor unit coil; S130, selectively adjust the operating frequency of the humidification module according to the real-time temperature. Those skilled in the art can understand that when the air conditioner needs to perform self-cleaning, since the self-cleaning effect of the air conditioner has a great relationship with the intensity of frosting, and the intensity of frosting has a great relationship with the indoor humidity, If the moisture in the indoor air is used for frosting, if the indoor air quality is poor, when frosting, the dust in the air will also be brought in, which will affect the self-cleaning effect. Therefore, during the self-cleaning process of the air conditioner, the humidification module is activated to humidify the indoor air to meet the frosting requirement during the self-cleaning process, and at the same time, the self-cleaning effect is avoided due to poor air quality.

In addition, since the temperature of the heat exchanger of the indoor unit decreases gradually during the self-cleaning process of the air conditioner, for better frosting effect, the operating frequency of the humidification module can be changed with the temperature of the heat exchanger of the indoor unit . Specifically, in step S110 , in the process of just entering the self-cleaning process, the working frequency of the humidification module is set to be the first preset working frequency, and it is assumed that the value of the first preset working frequency is 1. Then go to step S120 to obtain the real-time temperature of the indoor unit coil. In this step, the temperature sensor installed on the indoor unit coil can be used for detection.

After step S120, enter step S130, and selectively adjust the operating frequency of the humidification module according to the real-time temperature. In step S130, the operating frequency of the humidification module is increased as the real-time temperature decreases, and when the real-time temperature drops to a preset temperature, the operating frequency of the humidification module is fixed at a second preset operating frequency. Wherein, the second preset working frequency>the first preset working frequency. It should be noted that a reasonable temperature value can be determined by those skilled in the art through experiments. For example, at this temperature value, the operating frequency of the humidification module is fixed at 1.5 or 2 or other reasonable operating frequencies. It should be noted that the process of increasing the operating frequency of the humidification module as the real-time temperature decreases may be linear or non-linear, which can be determined by those skilled in the art through experiments according to actual application scenarios.

Further, in step S130, after the humidification module works at the second preset working frequency for a first preset time, the working frequency of the humidification module is decreased as the working time increases, and after the humidification module continues to work for a second preset time to stop the humidification module from working. The first preset time and the second preset time can be flexibly determined by those skilled in the art according to the actual situation, and the first preset time and the second preset time are not limited herein.

As mentioned above, in the technical solution of the present invention, the process of selectively adjusting the working frequency of the humidification module according to the real-time temperature can be briefly described as follows: when starting self-cleaning, the working frequency of the humidification module is positioned at 1, and then the operation frequency of the humidification module is set to 1. The working frequency gradually increases with the decrease of the temperature of the heat exchanger of the indoor unit. When the heat exchanger increases to the preset temperature, the working frequency of the humidification module is fixed at a value higher than 1, and the humidification module is set at this value. Working frequency for a period of time. After a period of time, the humidification module is then lowered as the working time increases. After that, after the humidification module works for a period of time, the humidification module is stopped from working. The above is to adjust the working frequency of the humidification module according to the real-time temperature of the heat exchanger of the indoor unit, so as to achieve a better frosting effect.

In a possible implementation manner, before step S110 is performed, the air conditioner self-cleaning and humidifying control method of the present invention further includes: acquiring indoor air humidity and dust value in the indoor air; when the air humidity is higher than a preset humidity and When the dust value is higher than the preset value, or when the air humidity is lower than the preset humidity, step S110 is selectively performed.

Specifically, when the air humidity is higher than the preset humidity and the dust value is higher than the preset value, or when the air humidity is lower than the preset humidity, the water quality information in the water storage cavity is obtained; according to the water quality information, it is judged whether to execute step S110. Specifically, when the water quality information meets the preset water quality standard, step S110 is executed; when the water quality information does not meet the preset water quality standard, step S110 is not executed. If the indoor air is humidified with poor water quality, the indoor air may be polluted, and the dust in the air will be brought into the air when frosting, which will affect the self-cleaning effect. Only clean water can have a better cleaning effect. Therefore, only when the water quality information meets the preset water quality standard, the humidification module can humidify the indoor air, so as to prevent the indoor air from being polluted.

Further, in the case where step S110 is not performed, a reminder message is issued. Wherein, the reminder information is used to remind the user to replace the water in the water storage cavity. As an example, the water in the water storage cavity is condensed water generated by the purified indoor unit heat exchanger, or the water in the water storage cavity is water added by the user. That is to say, the water in the water storage cavity may be the collected condensed water of the indoor heat exchanger, or may be the pure water added actively by the user.

It should be noted that the preset humidity and preset value in the above can be flexibly set by those skilled in the art according to actual needs. For example, according to the application scenario of the air conditioner and the actual frosting intensity required for self-cleaning, it is enough to set the preset humidity that can meet the frosting intensity; the dust value can be the PM2.5 value, and PM2.5 means the air per cubic meter The content of fine particles, such as the PM2.5 concentration index of 10 micrograms/cubic meter, is 10. As an example, the preset value can be set to any value between 100-150.

So far, the technical solutions of the present invention have been described with reference to the preferred embodiments shown in the accompanying drawings, however, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
