As shown in FIG. 1, FIG. 1 is a schematic diagram of the terminal structure of an air conditioner according to an embodiment of the present application.

The terminal of the embodiment of the present application is an air conditioner.

As shown in FIG. 1, the terminal may include a processor 1001 (eg, CPU), a memory 1002, a communication bus 1003 and an air purification load 1004. A communication bus 1003 is configured to provide connections and communications between these components.

The memory 1002 may be a high speed RAM memory or a non-volatile memory such as a magnetic disk memory. As shown in FIG. 1, a memory 1002 as a kind of computer storage medium may contain an air conditioner control program, while the processor 1001 stores the air conditioner control program stored in the memory 1002. It may be configured to call and perform the following operations.

When the air conditioner activates the air purification load, detects the rotation speed of the indoor fan, and when the rotation speed is lower than the predetermined rotation speed, obtains the power on time and power off time of the air purification load in the air conditioner, The air purification load is controlled so as to operate intermittently based on the power ON time and the power OFF time.

In this embodiment, according to the above scheme, when the rotation speed is lower than the predetermined rotation speed, the power-on time and power-off time of the air purification load in the air conditioner are obtained, and according to the power-on time and power off time, , by controlling the air purification load to operate intermittently, avoiding the phenomenon that the wall surface becomes black due to the long-term operation of the air purification load, and allowing the dust to be adsorbed on the filter in a timely manner; Improve the effectiveness of air conditioning.

Based on the above hardware architecture, an embodiment of the air conditioner control method of the present application is proposed.

Referring to FIG. 2, according to the flow schematic diagram of the first embodiment of the air conditioner control method of the present application, the air conditioner control method includes the following steps. Step S10, after the air conditioner activates the air purification load, detect the rotation speed of the indoor fan. In the present application, when the air conditioner is in normal operation, the air purification load is activated, and the air purification load generates negative ions to absorb dust and particulate matter in the air, and the suspended dust and particulate matter are removed from the air purification load. and guide the airborne dust and particulate matter in the air purification load onto the filter to exert the effect of purifying the air, and detect the rotation speed of the indoor fan.

Step S20, determine whether the rotation speed is lower than a predetermined rotation speed. The detected rotation speed is compared with the predetermined rotation speed of the system, and the air conditioner is controlled according to the magnitude relationship between the rotation speed and the predetermined rotation speed. For example, in this embodiment, the predetermined rotational speed may be in steps of 80% of the maximum rotational speed, and the detected rotational speed is compared to the 80% step of the maximum rotational speed.

Step S30, when the rotation speed is lower than the predetermined rotation speed, obtain the power-on time and power-off time of the air purification load in the air conditioner; When the rotation speed is lower than the predetermined rotation speed, at this time, the air volume at the intake of the air conditioner is relatively small, that is, the suction force at the intake is relatively small, and the air purification load is continuously operated, and the air purification load will have a large amount of air. When the particulate matter is collected and the suction force of the air intake is relatively small, it is impossible to bring the particulate matter to the filter in a timely manner, which easily leads to the phenomenon that the wall surface becomes black. It is necessary to operate the air purification load inside intermittently to avoid the phenomenon that the wall surface tends to become black. According to the rotation speed of the indoor fan, the power on operation time and power off operation time of the air purification load in the air conditioner are obtained. Time is the period of non-operation between two consecutive energizations of the air purification load.

Step S40, the air purification load is controlled to operate intermittently based on the power ON time and the power OFF time.

The air purification load is controlled to operate intermittently based on the obtained power ON time and power OFF time, and the air purification load operates according to the power ON time. Stop the operation by cutting time. Negative ions generated by the air purification load adsorb airborne dust and particulate matter to the air purification load. At this time, if the rotation speed of the indoor fan is lower than the predetermined rotation speed, the suction force of the air conditioner intake port is compared. It is necessary to move the particulate matter in the air purification load to the filter after the power on time and the power off time to avoid the blackening of the wall caused by the airborne dust and particulate matter adhering on the wall.

In the technical solution proposed by the present embodiment, when the rotation speed is lower than the predetermined rotation speed, the power on time and the power off time of the air purification load set in the air conditioner are obtained, and the power on time and the power The air purification load is controlled so as to operate intermittently according to the disconnection time. When the air purification load operates normally, the negative ions generated by the air purification load gather together with the particulate matter in the air, and a large amount of particulate matter gathers at the intake of the air conditioner. When the rotation speed is less than the predetermined rotation speed, at this time, the wind speed of the air conditioner is also lower than the set wind speed, the suction force for particulate matter is relatively small, and the particulate matter collected in the air purification load is relatively large. Adsorption on the filter in time is not possible. At this time, the air purification load is controlled to operate intermittently depending on the power ON time and power OFF time to reduce the particulate matter that collects at the air purification load and remove all the particulate matter from the air conditioner intake. To avoid the phenomenon that the wall surface becomes black due to the particulate matter being adsorbed on the wall surface.

Referring to FIG. 3, FIG. 3 is a second embodiment of the air conditioner control method of the present application. According to the first embodiment, the step S30 is to determine the power supply time of the air purification load based on the rotation speed. and step S31 of obtaining a power-off time, wherein the power-on time is longer as the rotation speed is higher.

When the rotation speed is lower than a predetermined rotation speed, the power-on time and the power-off time of the air purification load are obtained according to the rotation speed. There is a one-to-one correspondence between the rotation speed and the power supply time, and there is a linear relationship between the rotation speed and the power supply time. The higher the rotation speed of the indoor fan, the longer the power supply time of the air purification load. . The power-off time of the air purification load may have a mapping relationship with the rotational speed of the indoor fan, and is obtained by subtracting the power-on time of the air purification load from the period of intermittent operation of the air purification load. You can understand what you can do. Alternatively, the rotation speed section to which the rotation speed belongs is determined, and the power-on time and the power-off time of the air purification load are determined based on the rotation speed section. Based on the detected rotation speed of the indoor fan, the rotation speed section to which the rotation speed belongs is determined. The power supply time and the power supply off time of intermittent operation can be obtained, and it is easy to realize, and the phenomenon of causing the change of the power supply time due to the rotation speed fluctuation of the indoor fan is avoided.

When the rotation speed of the indoor fan is the lower limit of the rotation speed corresponding to the intermittent operation of the air purification load, the shortest time of power supply operation of the air purification load is shortest, and the shortest time of power supply operation of the air purification load is When T _mix =T _{on +off} *k1, and the rotational speed of the indoor fan is the upper limit of the rotational speed corresponding to the intermittent operation of the air purification load, the power-on operation time of the air purification load is the longest, and the air The maximum time of powered operation of the purification load is T _max =T _on+off *k2, where T _on+off is the period of intermittent operation of the air purification load, k1 can be 0.01, and k2 is 0.01. 8, and the numerical range of T _on+off can range from 10 seconds to 60 seconds. T _on+off is the period of intermittent operation of the air purification load, and the period may be a fixed value set in the system or a variable value. Obtain the intermittent operation period of the air purification load from the mapping relationship of , further obtain the mapping relationship between the air purification load and the power supply time from the rotation speed, and obtain the power supply time of the air purification load It would be understandable to do

It should be explained that the air purification load is controlled to operate with the shortest power-on operation time when the rotation speed is lower than the rotation speed lower limit of the intermittent operation of the air purification load. For example, when the rotation speed of the indoor fan is lower than the 1% level of the indoor fan, the air purification load is controlled so as to operate intermittently so that the power ON time is 2 seconds and the power OFF time is 16 seconds.

In the technical solution proposed by this embodiment, the power-on time and power-off time of the air purification load are obtained according to the rotation speed of the indoor fan, so that it is easy to control the air purification load to operate intermittently. . When the rotation speed is lower than the predetermined rotation speed, that is, the wind speed is lower than the predetermined wind speed, the air purification load is controlled to operate intermittently according to the rotation speed, so that the control is accurate and the particulate matter is filtered. The blackening of the wall surface is avoided by adsorbing the particulate matter on the wall surface.

Please refer to FIG. 4, which is the third embodiment of the air conditioner control method of the present application, according to the second embodiment, the step S30 further obtains the humidity of the indoor environment where the air conditioner is placed. including step S32 and step S33 of determining whether the humidity is higher than the predetermined humidity, and when the humidity is higher than the predetermined humidity, executing step S31, that is, the air purification load according to the rotational speed; Get the power on time and power off time of .

When the rotation speed is lower than a predetermined rotation speed (for example, the predetermined rotation speed can be 80% of the maximum rotation speed), the humidity of the indoor environment where the air conditioner is placed is obtained, and the humidity is: It refers to the percentage ratio of the actual water vapor pressure in the air to the saturated water vapor pressure at the current temperature. By installing a temperature sensor on the indoor heat exchanger of the air conditioner, the humidity of the indoor environment where the air conditioner is placed is obtained. The obtained humidity of the indoor environment is compared with the predetermined humidity, and when the humidity of the indoor environment is higher than the predetermined humidity, the power on time and the power off time of the air purification load are obtained according to the rotation speed.

In an embodiment of the present application, when the humidity is higher than the default humidity (the default humidity is 50%), in order to avoid increasing energy consumption by keeping the air purification load powered on for a long period of time, and At the same time, when the rotation speed is low, if too much particulate matter accumulates in the air purification load, it will be impossible to adsorb the particulate matter on the filter in a timely manner, and the wall surface will easily become black, so the indoor fan will not rotate. The power-on time and power-off time of the air purification load are obtained according to the speed, so as to reduce the energy consumption of the air conditioner and avoid the blackened wall phenomenon as much as possible.

Referring to FIG. 5, FIG. 5 is the fourth embodiment of the air conditioner control method of the present application. According to the third embodiment, after the step S33, the step S30 further includes that the humidity is a predetermined humidity if it is less than, a step S34 of obtaining an adjustment coefficient based on the humidity; obtaining a power-on time and a power-off time based on the rotational speed; and obtaining the power-on time and the power-off time based on the adjustment coefficient; and a step S36 of setting the power ON time and power OFF time after the adjustment to the power ON time and power OFF time of the air purification load.

When the humidity is lower than the predetermined humidity, at this time the room is relatively dry, there are more airborne dust and particulate matter, and the adjustment factor is obtained according to the humidity. It will be appreciated that there is a one-to-one correspondence between the adjustment factor and humidity, or that the adjustment factor corresponds to the humidity interval to which the humidity belongs. After acquiring the power energization time of the air purification load according to the rotational speed, multiplying it by an adjustment coefficient, the adjusted power energization time and power off time are set as the power energization time and power off time of the air purification load, and the power energization By controlling the air purification load to operate intermittently according to the time and the power off time, the air purification load will generate less negative ions, and a large amount of particulate matter will accumulate in the air purification load. To avoid the phenomenon that the wall surface tends to become black.

In an embodiment of the present application, obtaining the humidity of the indoor environment where the air conditioner is placed on the condition that the rotation speed is lower than the predetermined rotation speed, and obtaining the adjustment coefficient when the humidity is lower than the predetermined humidity, such as: The adjustment factor is between 0.3 and 0.9. By obtaining the power energization time according to the rotation speed and multiplying it by an adjustment coefficient, the power energization time during which the air purification load operates intermittently is obtained, and the power energization after adjustment is obtained from the period in which the air purification load intermittently operates. By subtracting the time, the power off time of the air purification load after adjustment is obtained. In other words, the power supply time of the original air purification load is attenuated, the power supply time of the air purification load is precisely adjusted and controlled, the power supply time of the air purification load is shortened, and the power supply time of the air purification load is reduced. Reduces the chance of walls turning black.

Referring to FIG. 6, FIG. 6 is a fifth embodiment of the air conditioner control method of the present application. According to the first embodiment, after the step S20, the air conditioner control method further comprises: A step S50 of continuously operating the air purification load is included when the speed is higher than the rotational speed.

When the rotation speed of the indoor fan is higher than the specified rotation speed, at this time the suction force of the air conditioner inlet is relatively large, and the continuous operation of the air purification load will collect a large amount of floating dust and particulate matter. It can be carried over a filter, which improves air quality while reducing the possibility of wall blackening. When the rotational speed is higher than the predetermined rotational speed, further comprising the following steps. Obtain the humidity of the indoor environment where the air conditioner is placed, and when the humidity is higher than the predetermined humidity, the particulate matter in the room is relatively small, and the air purification load is continuously operated to generate negative ions. At the same time, the airborne dust and particulate matter can be collected at the air purification load as quickly as possible, and the strong suction force of the air inlet can easily be carried onto the filter. When the humidity is lower than the predetermined humidity, the indoor environment is relatively dry. At this time, in order to avoid the phenomenon that the wall surface tends to be blackened due to a large amount of suspended dust and particulate matter gathering at the air purification load, intermittent Control the air purification load to run and obtain power on and off times of the air purification load based on humidity to ensure that particulate matter that collects on the air purification load can be brought onto the filter. do. Here, the higher the humidity, the longer the power supply time. To reduce the energy consumption of an air purification load, and to avoid the phenomenon that a wall surface becomes black due to the accumulation of a large amount of particulate matter as much as possible.

In addition, when the rotation speed of the indoor fan is higher than the predetermined rotation speed, the suction force at the air conditioner inlet is relatively large, and the large amount of floating dust and particulate matter collected by the continuous operation of the air purification load can be It should be mentioned that either can be brought onto the filter, which improves air quality while reducing the possibility of wall blackening. It should be mentioned that when the rotation speed is higher than the predetermined rotation speed, it further includes the step of obtaining the pollutant concentration of the indoor environment where the air conditioner is placed. The pollution concentration is the concentration of particulate matter in the indoor environment, such as the concentration of pm2.5 in the indoor environment. to obtain the pollutant concentration of the indoor environment where the air conditioner is placed. When the pollution concentration is higher than the predetermined pollution concentration, the particulate matter in the room is relatively large, and the air purification load is continuously operated at this time to ensure the indoor air quality. It is necessary to ensure the air quality of the indoor environment by generating negative ions through the air purification load and adsorbing the floating dust in the air. It is possible to ensure that the material is carried on the filter by a large amount of air, and to reduce the phenomenon that the wall surface in contact with the air conditioner tends to be blackened. When the pollution concentration is less than the predetermined pollution concentration, it indicates that the air quality in the room is not bad at this time, but if the suction force of the air inlet is relatively large at this time, the particulate matter collected in the air purification load will not be filtered. However, in this case, if the air purification load is operated continuously, the energy consumption of the air conditioner will increase, so in this case, it is necessary to operate the air purification load intermittently. be. Under the condition of ensuring indoor air quality and energy saving, the power-on time of the air purification load is obtained according to the pollution concentration, where the higher the pollution concentration, the longer the power-on time. To reduce the energy consumption of an air purification load, to reduce particulate matter in the environment where an air conditioner is placed, and to avoid the phenomenon that the wall surface becomes black due to the diffusion of the particulate matter on the wall surface.

The invention further proposes a method for controlling an air conditioner.

Please refer to FIG. 7, which is a flow schematic diagram of the sixth embodiment of the air conditioner control method of the present invention, wherein the air conditioner control method includes the following steps. Step S100, after the air conditioner activates the air purification load, obtain the humidity of the indoor environment where the air conditioner is placed. In the present invention, when the air conditioner is in normal operation, the air purification load is activated, the air purification load generates negative ions to absorb dust and particulate matter in the air, and the suspended dust and particulate matter purify the air. It has the effect of purifying the air by allowing it to collect at the load and directing the airborne dust and particulate matter in the air purifying load onto the filter. Then, by installing a humidity sensor in the indoor unit of the air conditioner, the humidity of the indoor environment where the air conditioner is placed is obtained, and the humidity is the actual water vapor pressure in the air and the saturated water vapor pressure at the current temperature. refers to the percentage of the ratio of

Step S200, determine whether the humidity is lower than a predetermined humidity. Comparing the obtained humidity of the indoor environment with the default humidity of the system, comparing the magnitude relationship between the humidity and the default humidity, and controlling the air conditioner accordingly. For example, in this embodiment, the default humidity can be 50%, and the obtained humidity is compared with 50% to determine the magnitude relationship between the environmental humidity and 50%.

Step S300, when the humidity is lower than the predetermined humidity, obtain the power-on time and power-off time of the air purification load in the air conditioner; When the humidity is lower than the specified humidity, the air inside the air conditioner is relatively dry, and there is more airborne dust and particulate matter in the room. If a large amount of particulate matter accumulates, in this case, if it is impossible to suck the accumulated particulate matter onto the filter in a timely manner, the particulate matter will diffuse to the wall surface, leading to the phenomenon of blackening the wall surface. In this case, it is necessary to avoid the phenomenon that the air purification load in the air conditioner operates intermittently and the wall surface tends to become black. Based on the humidity of the indoor environment where the air conditioner is placed, the power on operation time and power off operation time of the air purification load in the air conditioner are acquired, and the power on time is the power on and operation of the air purification load. The power-off time is the time during which the air purification load stops operating between two consecutive power-on operations.

Step S400, controlling the air purification load to operate intermittently according to the power-on time and power-off time;

When the humidity is lower than the specified humidity, airborne dust and particulate matter are likely to occur in the indoor environment. operates according to the time when the power supply is turned on, and after the air purification load operates for a certain period of time, it stops operating according to the time when the power supply is turned off. Negative ions generated by the air purification load adsorb airborne dust and particulate matter to the air purification load, so it is necessary to move the particulate matter from the air purification load to the filter after the power is turned on and off. be. The intermittent operation of the air purification load avoids large amounts of particulate matter collecting at the air purification load and unable to be adsorbed on the filter in a timely manner. For example, when the humidity is lower than 50%, the air purification load is controlled so as to operate intermittently based on the obtained power ON time and power OFF time.

In the technical solution proposed by this embodiment, when the humidity is lower than the predetermined humidity, there are more airborne dust particles and particulate matter in the room, and the power supply time of the air purification load set in the air conditioner and the power-off time are obtained, and the air purification load is controlled so as to operate intermittently according to the power-on time and the power-off time. When the air purification load is normally powered on and running, the negative ions generated by the air purification load will collect with particulate matter in the air, and a relatively large amount of particulate matter will easily accumulate in the air purification load. At times, it is necessary to control the air purification load to operate intermittently based on the power on time and power off time. During the power down time, the air purification load is deactivated to reduce particulate matter collection at the air purification load, allowing a small amount of particulate matter in the air purification load to move with the wind onto the filter. By doing so, it is possible to avoid the phenomenon that the wall surface becomes black due to adsorption of particulate matter on the wall surface.

Please refer to FIG. 8, which is the seventh embodiment of the air conditioner control method of the present application. including step S310 of obtaining time, wherein the higher the humidity, the longer the power-on time;

When the humidity is lower than the predetermined humidity, the power on time and the power off time of the air purification load are obtained based on the humidity, the humidity and the power on time are in one-to-one correspondence, and the humidity and the power on time are obtained. There is a linear relationship between the values, and the higher the humidity of the indoor environment, the longer the power supply time of the air purification load. The power-off time of the air purification load may have a mapping relationship with the humidity of the indoor environment, and may be obtained by subtracting the power-on time of the air purification load from the intermittent operation cycle of the air purification load. You can understand what you can do. Alternatively, the humidity section to which the humidity belongs is determined, and the power-on time and the power-off time of the air purification load are determined based on the humidity section. Based on the obtained humidity of the indoor environment, the humidity section in which the humidity is placed is determined, and each humidity section corresponds to the power ON time and power OFF time of the air purification load, which is easy to realize. To easily control an air purification load accurately so as to operate according to the power supply time by avoiding the phenomenon of causing a change in the power supply time due to humidity fluctuations.

When the humidity of the indoor environment is the lower limit of the humidity corresponding to the intermittent operation of the air purification load, at this time, the time of power supply operation of the air purification load is the shortest, and the shortest time of power supply operation of the air purification load is T _mix . =T _{on +off} *k1, and when the humidity of the indoor environment is the upper limit of the humidity corresponding to the intermittent operation of the air purification load, the power supply operation time of the air purification load is the longest, and the power supply of the air purification load The maximum time of energized operation is T _max =T _{on +off} *k2, where T _{on +off} is the period of intermittent operation of the air purification load, k1 can be 0.2, and k2 can be 0.8. , and the numerical range of T _on+off can range from 10 seconds to 60 seconds. T _on+off is the period of intermittent operation of the air purification load, and the period may be a fixed value set in the system or a variable value. Obtaining the intermittent operation period of the air purification load according to the mapping relationship, further obtaining the mapping relationship between the air purification load and the power supply time from the humidity, and obtaining the power supply time of the air purification load. would be understandable.

It should be mentioned that when the humidity is below the lower humidity limit for intermittent operation of the air purification load, the air purification load is controlled to operate with the shortest power on operation time. For example, when the humidity in the room where the air conditioner is placed is lower than 20%, the air purification load is controlled so that the power is turned on for 2 seconds and turned off for 16 seconds.

In the technical solution proposed by this embodiment, the humidity of the environment in which the air conditioner is placed is obtained to obtain the power ON time and power OFF time of the air purification load, so the air purification load is intermittently operated. Make it easier to control. By controlling the air purification load to operate intermittently based on the humidity when the humidity is lower than the preset humidity, the control becomes more accurate and allows the particulate matter to be adsorbed on the filter, thus reducing the particulate matter. To avoid the phenomenon that the wall surface becomes black by adsorbing substances on the wall surface.

Referring to FIG. 9, FIG. 9 is an eighth embodiment of the air conditioner control method of the present application, and according to the sixth embodiment, after the step S200, the air conditioner control method further comprises that the humidity is a predetermined humidity When higher, it includes a step S500 of continuously running the air purification load.

When the humidity of the environment where the air conditioner is placed is higher than the specified humidity, at this time, the humidity in the room is relatively large, and there is not a large amount of suspended dust particles in the room, and the indoor air quality At this time, in order to further improve the air purification load, the air purification load is operated continuously to generate negative ions and collect a small amount of suspended dust particulate matter in the indoor air at the air purification load. A small amount of airborne dust particulate matter tends to migrate to the filter in the air conditioner, improving indoor air quality and reducing the possibility of blackening of walls in contact with the air conditioner.

Here, it should be explained that after step S40, the air conditioner control method further includes the step of obtaining the indoor pollution concentration where the air conditioner is located. The pollution concentration is the concentration of particulate matter in the indoor environment, such as the concentration of pm2.5 in the indoor environment. Obtain the indoor environment pollution concentration where the air conditioner is placed. When the pollution concentration is higher than the preset concentration, it means that the air quality in the room is not good, at this time, the air conditioner humidifier should be operated. It is necessary to control and control the air purification load to operate intermittently, and the power supply time of the air purification load is obtained by the humidity, so that the humidity of the indoor environment is increased under the action of the humidification device. and when the humidity is higher than the predetermined humidity, step S50 is executed, that is, the air purification load is operated continuously. For example, if the predetermined pollution concentration is 50ug/m3 and the predetermined humidity is 50%, and the indoor environmental pollution concentration is greater than 50ug/m3 and the indoor environmental humidity is less than 50%, the air is first purified by humidity. Obtaining the power-on time of the load and controlling the air purification load to operate intermittently according to the power-on time and power-off time, at the same time, the air conditioner starts the humidification function and the air conditioner is placed By obtaining the humidity of the environment in which the air is present and humidifying the environment in the room with a humidifier, the humidity of the indoor environment is increased, and the airborne dust particulate matter is collected in the air purification load, and the particulate matter is absorbed by the air purification load. It also makes it easier to be adsorbed on the filter. Thereafter, the air purification load is operated continuously when the humidity is greater than 50%. When the indoor air quality is poor, the humidifying function of the air conditioner is activated to create conditions for continuous operation of the air purification load, making it easier to guarantee the indoor air quality. When the humidity of the indoor environment where the air conditioner is placed is lower than the predetermined humidity and the pollution concentration is lower than the predetermined pollution concentration, the energy consumption of the air purification load is saved and the air quality of the environment where the air conditioner is placed is improved. At this time, the power supply time and power supply time of the air purification load are obtained directly according to the humidity of the indoor environment, and the air purification load is operated intermittently according to the power supply time and power supply off time. to control.

In the technical solution proposed in this embodiment, when the humidity is higher than the predetermined humidity, the air purification load is controlled so that the indoor environment has relatively little airborne dust particulate matter, and the air purification load is operated continuously. To make it easier to further improve the air quality of an indoor environment.

Referring to FIG. 10, FIG. 10 is the ninth embodiment of the air conditioner control method of the present application. step S330 of determining whether the rotation speed is less than a predetermined rotation speed; step S340 of obtaining an adjustment coefficient according to the rotation speed when the rotation speed is less than the predetermined rotation speed; step S340 of power supply time based on the humidity; A step S350 of obtaining the power supply time and the power supply cutoff time and adjusting the power supply time and the power supply cutoff time by the adjustment coefficient, and Step S360, which is the disconnection time.

When the humidity is lower than the predetermined humidity, the air purification load is controlled to operate intermittently, and the parameters of the indoor fan are obtained to obtain the rotation speed of the indoor fan, and the rotation speed and the predetermined rotation speed are calculated. It is necessary to compare the magnitude relationship between them. The predetermined rotation speed is 80% of the maximum rotation speed, when the rotation speed is less than the predetermined rotation speed, at this time the intake air amount at the air inlet of the indoor fan is relatively small, that is, the air inlet has less particles in the air purification load. Since the suction force for particulate matter is relatively small, it is difficult to move particulate matter onto the filter, which easily leads to the phenomenon that the wall surface becomes black. Therefore, at this time, an adjustment coefficient is obtained based on the rotational speed, the adjustment coefficient is between 0.3 and 0.9, and the power supply time of the air purification load is obtained according to the humidity. Multiply the adjustment coefficient to obtain the adjusted power-on time, and subtract the adjusted power-on time from the intermittent operation period of the air purification load to obtain the power-off time of the air purification load after adjustment. . Then, the air purification load is controlled to operate intermittently during the power on time and power off time after the adjustment, so that the air purification load generates less negative ions, and a large amount of particulate matter is removed from the air. Avoid the phenomenon that the wall tends to blacken due to the load gathering and not all moving to the filter.

It should be mentioned that the power-on time and power-off time are obtained according to the humidity when the rotation speed is greater than a predetermined rotation speed. When the rotation speed is higher than the predetermined rotation speed, the intake air volume of the intake port is relatively large, that is, the suction force at the intake port is relatively large, and any particulate matter collected in the air purification load moves onto the filter with the intake air. can. Then, control the air purification load to operate intermittently, and acquire the power supply time and power off time when the air purification load intermittently operates based on humidity to ensure indoor air quality. while at the same time reducing the energy consumption of the air purification load.

In the embodiment of the present invention, obtaining the rotation speed of the indoor fan of the air conditioner under the condition that the humidity is lower than the predetermined humidity, and obtaining the adjustment factor when the rotation speed is lower than the predetermined rotation speed, such as the adjustment factor is between 0.3 and 0.9. By obtaining the power-on time of the air purification load based on the humidity and applying the adjustment coefficient, the power-on time and the power-off time during which the air purification load operates intermittently are obtained. In other words, the power supply time of the original air purification load is attenuated, the power supply operation time of the air purification load is reduced, the particulate matter that collects in the air purification load is reduced, and the particulate matter diffuses to the wall surface. This reduces the possibility of the phenomenon that the wall surface becomes black. By attenuating the power supply time of the air purification load, the control becomes more accurate and easier to implement.
