Detecting the purification capability of the negative ion purification device;

Referring to FIG. 2, a first embodiment of a method for controlling an air conditioner according to the present application. The method for controlling an air conditioner includes:

In step S10, when the air purification instruction is received, the power-on duration of the air conditioner is obtained.

In step S20, when the power-on duration is longer than the first preset duration, the negative ion purification device is controlled to operate.

When the air conditioner performs air purification, the indoor fan rotates, and the negative ion purification device generates a large number of negative ions. The negative ions are combined with the positively charged particles such as dust, odor molecules, bacteria, and smoke carried in the return air to condense and eliminate PM2. 5 hazards, to achieve the role of cleaning indoor air. In order to remove fine particles such as dust in the indoor environment, the indoor air is introduced into the air-conditioning indoor unit from the air return through the operation of the indoor fan. In order to allow the negative ions to settle with the fine particles in the introduced indoor air, while avoiding the settled particles Falling into the air conditioner indoor unit will damage the internal components of the indoor unit and affect the working efficiency of the air conditioner. A filter screen is provided at the air return port of the indoor unit of the air conditioner, and a negative ion purification device is provided between the filter screen and the indoor heat exchanger. The collected and settled particles are attached to the filter screen, and are blocked by the filter screen outside the air conditioner indoor unit casing, and fall off under the action of gravity. Furthermore, the particles that cannot fall off naturally can be completely removed by washing the filter.

When the air conditioner operates for a long time and a large amount of dust particles are collected on the filter, the return air resistance of the air conditioner is increased, the working efficiency of the air conditioner is reduced, and the air conditioning capacity of the air conditioner is poor. The user will choose to remove the filter of the indoor unit of the air conditioner for cleaning. The user usually removes the filter when the air conditioner is powered off. When the filter is removed, the user is in close contact with the air conditioner, causing the user to get an electric shock. After the filter is cleaned, put the filter back into the indoor unit, and power on the air conditioner again.

If the air conditioner is powered on again, immediately start the negative ion purification device to purify the indoor air. After the filter is cleaned, water droplets may still remain on the filter. When dust, bacteria, smoke and other particles condensed by negative ions are attached to the wet filter, a small amount The mixture of dust particles and water adheres to the filter screen, which easily causes the filter screen to be blocked, increases the return air resistance of the air conditioner, and reduces the air cleaning strength of the air conditioner.

Based on the above analysis, the present application provides a method for controlling an air conditioner. When the air conditioner receives an air purification instruction, it obtains the power-on duration of the air conditioner. The power-on time is the time measured by the timer when the air conditioner receives an air purification command from the moment the power is turned on. When the power-on duration of the air conditioner is longer than the first preset duration, it can be explained that the filter is installed for a certain time, and the possibility that the filter of the air conditioner indoor unit is still wet is greatly reduced. At this time, the negative ion purification device is controlled to operate to purify the indoor air. The negative ions generated by the negative ion purification device can be combined with positively charged particles such as dust, odor molecules, bacteria, and smoke in the return air to condense and precipitate. The damp filter screen will cause the filter screen to be blocked and affect the working efficiency of the air conditioner.

In addition, the method for controlling an air conditioner described in this application further includes: when the air conditioner receives an air purification instruction, generates an air purification request according to the air purification instruction, and sends the air purification request to a server corresponding to the air conditioner, so When the server receives an air purification request sent by the air conditioner, the server obtains a power-on duration of the air conditioner, and when the power-on duration is longer than a first preset duration, controls the air conditioner to operate a negative ion purification device for indoor air. Purification.

In this embodiment, when the air conditioner receives the air purification instruction, it obtains the power-on duration of the air conditioner. When the power-on duration of the air conditioner is longer than the first preset duration, it can be explained that the filter is installed for a certain time, and the probability that the filter of the air conditioner indoor unit is still wet is greatly reduced. Ensure that the filter screen is dry when the negative ion purification device is running, which solves the technical problem of turning on the air cleaning mode when there is water on the filter screen, and the dust sticks to the filter screen when dust is adsorbed on the surface of the filter screen.

Further, referring to FIG. 3, a second embodiment of a method for controlling an air conditioner according to the present application, based on the above-mentioned first embodiment, before step S20, the method further includes:

In step S30, it is determined whether the power-on duration is greater than the first preset duration.

When the power-on duration is longer than the first preset duration, step S20 is executed to control the operation of the negative ion purification device.

Step S40: when the power-on duration is less than or equal to the first preset duration, obtain an operating state of the air conditioner, and determine whether the operating state is standby or operating.

In step S50, when the operating state is standby, the air supply mode is turned on.

In step S60, when the operating state is running, the step of controlling the operation of the negative ion purification device is executed after a third preset period of time.

After obtaining the power-on duration of the air conditioner, when the power-on duration of the air conditioner is longer than the first preset duration, it can be explained that the filter has been installed for a certain time, and the probability that the air conditioner indoor unit is still wet is small. In contrast, when the power-on duration of the air conditioner is less than or equal to the first preset duration, the probability that the filter is still wet is high at this time, and at this time, running the negative ion purification device may easily cause the filter to be blocked. In order to accelerate the drying speed of the filter, when the power-on time of the air conditioner is less than or equal to the first preset time period, the current operating state of the air conditioner is judged. If the current air conditioner is in the standby state, the air conditioner is controlled to enter the air supply mode; If the air conditioner is currently in a running state (operation states include: cooling, heating, dehumidification, air supply, etc.), the air conditioner is controlled to maintain the current running state. Therefore, when the air conditioner is in a standby state, after the user sends an air purification instruction, the air conditioner does not respond, which causes the user to think that the air conditioner is malfunctioning, which causes user distress.

In addition, when the current air conditioner is in a standby state, the air conditioner is controlled to enter the air supply mode. After the second preset time period of the air supply mode is operated, step S20 is performed to control the air conditioner to start the negative ion purification device to purify the indoor air. When the air conditioner is currently in the running state, after the air conditioner maintains the current running state for a third preset period of time, step S20 is executed to control the air conditioner to start the negative ion purification device to purify the indoor air. It should be noted that the first preset duration, the second preset duration, and the third preset duration may be the same or different. When the three are different, the third preset duration should be the minimum duration. According to the characteristics of different air conditioners, the first preset time period, the second preset time period, and the third preset time period may be selected from 0.5 to 1 hour.

In this embodiment, when the power-on duration of the air conditioner is less than or equal to the first preset duration, the probability that the filter is still wet is high at this time. At this time, running the negative ion purification device may easily cause the filter to be blocked. In order to accelerate the drying speed of the filter, when the power-on time of the air conditioner is less than or equal to the first preset time period, the current operating state of the air conditioner is judged. If the current air conditioner is in the standby state, the air conditioner is controlled to enter the air supply mode; If the air conditioner is not currently running, control the air conditioner to maintain the current running state. When the air conditioner is currently running, control the air conditioner to start the negative ion purification device after the air conditioner maintains the current running state for a third preset period of time. Purify the indoor air. Therefore, when the air conditioner is in a standby state, after the user sends an air purification instruction, the air conditioner does not respond, which causes the user to think that the air conditioner is malfunctioning, which causes user distress.

Further, referring to FIG. 4, a third embodiment of a method for controlling an air conditioner according to the present application, based on the above-mentioned first or second embodiment, before step S20, the method further includes:

Step S70: Acquire environmental parameters of the environment where the air conditioner is located, wherein the environmental parameters include at least one of the indoor heat exchanger temperature, the indoor temperature, and the indoor humidity;

Step S80: Determine the first preset duration according to the environmental parameters, and execute the step of controlling the operation of the negative ion purification device when the power-on duration is longer than the first preset duration.

Because the higher the temperature of the indoor heat exchanger of the air conditioner, the faster the moisture evaporates, and the faster the filter screen near the heat exchanger dries, the shorter the time it takes to wait for the filter screen to dry. Similarly, the higher the indoor ambient temperature, the faster the filter will dry; the greater the indoor humidity, the slower the filter will dry. In summary, it can be seen that the drying time of the filter is related to the indoor environment, and the time required to dry the filter is different in different environments. Therefore, the environmental parameters of the environment where the air conditioner is located are obtained, and the first preset duration is determined according to the environmental parameters, and then the first preset duration is used as a judgment to determine whether the operation of the negative ion purification device can be controlled, that is, when the power-on duration is longer than the first For a preset period of time, the negative ion purification device is controlled to run; otherwise, the negative ion purification device is not operated. Among them, the indoor evaporator temperature and the indoor temperature can be detected by a temperature sensor, and the indoor humidity can be detected by a humidity sensor. For example, when the current temperature of the indoor heat exchanger is 50 ° C, the indoor temperature is 10 ° C, and the indoor humidity is 30%, the corresponding first preset duration is 40 minutes; the current temperature of the indoor heat exchanger is 10 When the indoor temperature is 28 ° C and the indoor humidity is 60%, the corresponding first preset duration is 50 minutes. Specifically, different air conditioners have different characteristics, and the first preset duration corresponding to different environmental parameters of each type of air conditioner can be obtained through experiments.

In this embodiment, the environmental parameters of the environment in which the air conditioner is located are obtained, and the first preset duration is determined according to the environmental parameters, and then the first preset duration is used as a criterion for judging whether the operation of the negative ion purification device can be controlled, that is, when the power is turned on When the duration is longer than the first preset duration, the negative ion purification device is controlled to operate; otherwise, the negative ion purification device is not operated. The first preset duration is determined according to environmental parameters, which can avoid the first preset duration being too short, and the phenomenon that the filter is not completely dry, that is, the operation of the negative ion purification device has been controlled, causing the filter to be blocked; the first preset can also be avoided The time is too long, leading to the problem that the negative ion purification device does not operate for a long time after the filter is dried, the indoor air cannot be optimized in time, and the air purification efficiency of the air conditioner is low.

Further, referring to FIG. 5, a fourth embodiment of a method for controlling an air conditioner according to the present application, based on any one of the foregoing first to third embodiments, before step S10, the method further includes:

In step S90, when an air purification instruction is received, the humidity of the air on the surface of the filter of the air conditioner is detected.

In step S100, it is determined whether the humidity of the air on the surface of the filter is greater than a preset humidity.

When the humidity of the air on the surface of the filter is greater than the preset humidity, step S10 is performed, that is, obtaining the power-on duration of the air conditioner.

The user may power off the air conditioner for reasons other than cleaning the filter, and then power it on again. Therefore, the power-on time may not be the time between when the filter is installed in the air-conditioning indoor unit and when the air purification instruction is received. Therefore, in order to accurately determine whether the filter has been cleaned, when the air purification is received, a humidity detection device is used to detect the air humidity on the surface of the filter. When the air humidity on the surface of the filter is less than or equal to the preset humidity, it means that the current filter is dry. You can directly start the negative ion purification device to optimize the indoor air. When the air humidity on the surface of the filter is greater than a certain preset humidity, describe the filter. The network is wet, and then step S10 is performed to obtain the power-on time of the air conditioner. The power-on time is used to determine the appropriate time to control the air conditioner to operate the negative ion purification device. Without clogging the filter, it purifies the indoor air and improves the air conditioner's performance. Work efficiency, avoid damage to air conditioner components and prolong service life.

In addition, an infrared detection device can also be used to detect the presence of water drops on the surface of the filter. When water drops are present, the filter is wet, and then step S10 is performed to obtain the power-on duration of the air conditioner. The appropriate time is determined by the power-on duration. Control the air conditioner to operate the negative ion purification device to purify the indoor air without clogging the filter; when no water drops are present, it means that the current filter is dry, and the negative ion purification device can be started directly to optimize the indoor air.

In this embodiment, in order to accurately determine whether the filter screen has been cleaned, when the air purification execution is received, a humidity detection device is used to detect the air humidity on the surface of the filter screen. When the air humidity on the surface of the filter is less than or equal to the preset humidity, it means that the current filter is dry. You can directly start the negative ion purification device to optimize the indoor air. When the air humidity on the surface of the filter is greater than a certain preset humidity, describe the filter. The network is wet, and then step S10 is performed to obtain the power-on time of the air conditioner. The power-on time is used to determine the appropriate time to control the air conditioner to operate the negative ion purification device. Without clogging the filter, it purifies the indoor air and improves the air conditioner's performance. Work efficiency, avoid damage to air conditioner components and prolong service life.

In step S130, when the purification capability of the negative ion purification device is less than a preset purification capability value, the operation of the negative ion purification device is stopped.

The main body of the negative ion purification device is a negative ion generator, which is composed of external circuits and internal circuit components that generate high voltage negative ions. When foreign matter such as water drops, flying insects fall into the external circuit, and the purification capacity of the negative ion purification device is reduced, stop the machine and wait for the foreign matter to be removed. The purification capacity of the negative ion purification device will automatically return to normal. If the abnormal operation continues, the internal circuit components will be damaged, causing irrecoverable damage. You can only replace parts to restore the purification ability.

After the air conditioner runs the negative ion purification device, detect the current purification capacity of the negative ion purification device, and determine whether the purification capacity of the negative ion purification device is less than the preset purification capacity value. When the purification capacity of the negative ion purification device is less than the preset purification capacity value, It is determined that the negative ion purification device is faulty, and the operation of the negative ion purification device is stopped. When the purification capacity of the negative ion purification device is greater than or equal to the preset purification capacity value, the negative ion purification device is normal, and continues to operate according to the operating procedure to purify the indoor air. When a malfunction of the anion purification device is detected, stopping the operation of the anion purification device in a timely manner can greatly reduce damage to the components of the anion purification device, reduce maintenance difficulty, and reduce maintenance costs.

The current method for detecting the purification capacity of the negative ion purification device is to detect the change of the concentration of negative ion in a unit time within a certain range of space of the negative ion purification device through the negative ion detection device, and obtain the negative ion purification device generated in the unit time according to the change in the concentration of negative ion. The number of negative ions. When the number of negative ions is less than a preset threshold, it is determined that the purification capability of the negative ion purification device is less than a preset purification capability value. Wherein, the preset threshold is the number of negative ions generated per unit time during the normal operation of the negative ion purification device of this model.

In addition, when there is a fault in the anion purification device, fault information is output, such as the flashing of the display lamp, the beep of the sound device, and the prompting short message to the bound mobile terminal. Notify the user of the cause of the failure through the fault prompt message, perform timely maintenance of the negative ion purification device, and restore the air purification function of the air conditioner.

In this embodiment, after the air conditioner runs the negative ion purification device, the current purification capacity of the negative ion purification device is detected, and it is determined whether the purification capacity of the negative ion purification device is less than a preset purification capacity value. When the purification capacity of the negative ion purification device is less than a preset When the purification capacity value is reached, it can be determined that there is a fault in the negative ion purification device, and the operation of the negative ion purification device is stopped. When the purification capacity of the negative ion purification device is greater than or equal to the preset purification capacity value, the negative ion purification device is normal, and continues to operate according to the operating procedure to purify the indoor air.
