Referring to fig. 2, a first embodiment of a control method of an air conditioner according to the present invention includes:
and step S10, acquiring the power-on time of the air conditioner when receiving the air purification instruction.
And step S20, when the electrifying time is longer than a first preset time, controlling the negative ion purification device to operate.
When the air conditioner purifies air, the indoor fan rotates, the anion purifying device generates a large amount of anions, the anions are combined with positively charged particles such as dust, smell molecules, bacteria, smog and the like carried in return air, and the anions are condensed and precipitated to eliminate PM2.5 harm, thereby achieving the effect of purifying the indoor air. In order to remove dust and other fine particles in the indoor environment, the indoor air is introduced into the indoor unit of the air conditioner from the air return opening through the operation of the indoor fan, and in order to enable negative ions and the fine particles in the introduced indoor air to be combined and settled, the condition that the settled particles fall into the indoor unit of the air conditioner to damage devices in the indoor unit and influence the working efficiency of the air conditioner is avoided. The air return port of the indoor unit of the air conditioner is provided with a filter screen, and a negative ion purification device is arranged between the filter screen and the indoor heat exchanger. The particles after gathering and settling are attached to the filter screen and separated outside the shell of the indoor unit of the air conditioner by the filter screen and fall off under the action of gravity. Further, for the particles which cannot naturally fall off, the particles can be thoroughly removed by cleaning the filter screen.
When the air conditioner operates for a long time and a large amount of dust particles are gathered on the filter screen, 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 screen of the indoor unit of the air conditioner for cleaning. The user usually can dismantle the filter screen under the air conditioner outage state, and when avoiding and dismantling the filter screen, the user closely contacts with the air conditioner, leads to the user to electrocute. And after the filter screen is cleaned, the filter screen is installed back to the indoor unit, and the air conditioner is powered on again.
If after the air conditioner is electrified again, the anion purification device is started immediately to purify the indoor air, water drops can still remain on the filter screen after the filter screen is cleaned, and when dust, bacteria, smoke and other particles condensed by anions are attached to the wet filter screen, a small amount of dust particles are mixed with water and are adhered to the filter screen, so that the filter screen is easily blocked, the air return resistance of the air conditioner is increased, and the air cleaning strength of the air conditioner is reduced.
According to the analysis, the invention provides a control method of an air conditioner, and the power-on time of the air conditioner is obtained when the air conditioner receives an air purification instruction. The power-on time is the time measured by the timer when the air conditioner receives the air purification instruction from the power-on time. When the power-on time of the air conditioner is longer than the first preset time, the filter screen is installed for a certain time, and the possibility that the filter screen of the indoor unit of the air conditioner is still wet is greatly reduced. At the moment, the operation of the negative ion purification device is controlled again to purify the indoor air, and the negative ions generated by the negative ion purification device are combined with positively charged particles such as dust, odor molecules, bacteria, smog and the like in return air to be condensed and precipitated on a wet filter screen, so that the filter screen is blocked, and the working efficiency of the air conditioner is influenced.
In addition, the control method of the air conditioner further comprises the steps that when the air conditioner receives an air purification instruction, the air conditioner generates an air purification request according to the air purification instruction, the air purification request is sent to a server corresponding to the air conditioner, the server obtains the power-on time length of the air conditioner when receiving the air purification request sent by the air conditioner, and when the power-on time length is longer than a first preset time length, the air conditioner is controlled to operate the anion purification device to purify the indoor air.
In this embodiment, when the air conditioner receives the air purification instruction, the power-on duration of the air conditioner is obtained. When the power-on duration of the air conditioner is longer than the first preset duration, it can be shown that the filter screen is installed for a certain time, and the probability that the filter screen of the indoor unit of the air conditioner is still wet is greatly reduced. Guarantee when anion purifier moves, the filter screen is dry state, has solved and has opened the air cleaning mode when having water to exist on the filter screen, and when the dust adsorbed to the filter screen surface, it glues the technical problem at the filter screen to lead to the dust easily.
Further, referring to fig. 3, a second embodiment of the method for controlling an air conditioner according to the present invention is based on the first embodiment, before the step S20, further comprising:
step S30, determining whether the power-on duration is greater than the first preset duration.
And when the power-on time length is greater than the first preset time length, executing a step S20, and controlling 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, obtaining an operation state of the air conditioner, and determining whether the operation state is standby or operating.
And step S50, when the operation state is standby, starting an air supply mode.
And step S60, when the operation state is operation, executing the step of controlling the operation of the negative ion purification device after a third preset time.
After the power-on time of the air conditioner is obtained, when the power-on time of the air conditioner is longer than a first preset time, it can be shown that the filter screen is installed for a certain time, and the probability that the filter screen of the indoor unit of the air conditioner is still wet is low. On the contrary, when the power-on duration of the air conditioner is less than or equal to the first preset duration, the probability that the filter screen is still wet at present is higher, and the filter screen is easily blocked when the anion purification device is operated. In order to accelerate the drying speed of the filter screen, when the power-on time of the air conditioner is less than or equal to a first preset time, judging the current running state of the air conditioner, and if the current air conditioner is in a standby state, controlling the air conditioner to enter an air supply mode; and if the air conditioner is in the current running state (the running state comprises refrigeration, heating, dehumidification, air supply and the like), controlling the air conditioner to keep running in the current running state. Therefore, the problem that the air conditioner fails to work and causes trouble to users due to the fact that the air conditioner does not react after the users send air purification instructions when the air conditioner is in a standby state is avoided.
In addition, when the air conditioner is in a standby state, the air conditioner is controlled to enter an air supply mode, and after the air supply mode is operated for a second preset time, the step S20 is executed, and the air conditioner is controlled 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 keeps running in the current running state for a third preset time, executing step S20, and controlling the air conditioner to start the negative ion purification device to purify the indoor air. It should be noted that the first preset time period, the second preset time period, and the third preset time period may be the same or different. When the three are different, the third preset time period should be the minimum time period. The first preset time, the second preset time and the third preset time can be 0.5-1 hour according to the characteristics of different air conditioners.
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 screen is still wet at present is high, and at this time, the filter screen is easily blocked by the operation of the negative ion purification device. In order to accelerate the drying speed of the filter screen, when the power-on time of the air conditioner is less than or equal to a first preset time, judging the current running state of the air conditioner, and if the current air conditioner is in a standby state, controlling the air conditioner to enter an air supply mode; and if the air conditioner is not in the current running state, controlling the air conditioner to maintain the current running state to run, and controlling the air conditioner to start the anion purification device to purify the indoor air after the air conditioner maintains the current running state to run for a third preset time when the air conditioner is in the current running state. Therefore, the problem that the air conditioner fails to work and causes trouble to users due to the fact that the air conditioner does not react after the users send air purification instructions when the air conditioner is in a standby state is avoided.
Further, referring to fig. 4, a third embodiment of the method for controlling an air conditioner according to the present invention is based on the first or second embodiment, before the step S20, the method further includes:
step S70, obtaining environmental parameters of the environment where the air conditioner is located, wherein the environmental parameters comprise at least one of the temperature of the indoor heat exchanger, the indoor temperature and the indoor humidity;
step S80, determining the first preset time according to the environmental parameter, and executing the step of controlling the operation of the negative ion purification device when the electrifying time is longer than the first preset time.
Since the higher the temperature of the indoor heat exchanger of the air conditioner is, the faster the moisture is evaporated, the faster the drying speed of the filter screen adjacent to the heat exchanger is, and the shorter the time required for waiting for the filter screen to dry is. Similarly, the higher the indoor environment temperature is, the faster the filter screen is dried; the greater the indoor humidity, the slower the screen drying speed. In summary, the drying time of the filter screen is related to the indoor environment, and the drying time of the filter screen is different in different environments. Therefore, the environmental parameters of the environment where the air conditioner is located are obtained, the first preset time is determined according to the environmental parameters, and then the first preset time is used as evidence for judging whether the operation of the negative ion purification device can be controlled or not, namely, when the power-on time is longer than the first preset time, the operation of the negative ion purification device is controlled, otherwise, the negative ion purification device is not operated. The indoor evaporator temperature and the indoor temperature can be detected by a temperature sensor, and the indoor humidity is detected by a humidity sensor. For example, when the temperature of the current indoor heat exchanger is detected to be 50 ℃, the indoor temperature is detected to be 10 ℃, and the indoor humidity is detected to be 30%, the corresponding first preset time is 40 minutes; when the temperature of the current indoor heat exchanger is detected to be 10 ℃, the indoor temperature is detected to be 28 ℃ and the indoor humidity is detected to be 60%, the corresponding first preset time is 50 minutes. Specifically, different air conditioners have different characteristics, and first preset time lengths corresponding to different environmental parameters of the air conditioners of various models can be obtained through experiments.
In this embodiment, the environmental parameter of the environment where the air conditioner is located is obtained, the first preset time is determined according to the environmental parameter, and then the first preset time is used as a proof for judging whether the operation of the negative ion purification device can be controlled, that is, when the power-on time is longer than the first preset time, the operation of the negative ion purification device is controlled, otherwise, the negative ion purification device is not operated. The first preset time is determined according to the environmental parameters, so that the phenomenon that the filter screen is not completely dried, namely the operation of the negative ion purification device is controlled, and the filter screen is blocked due to the fact that the first preset time is too short can be avoided; the problems that the anion purification device does not operate in a long time after the filter screen is dried, indoor air cannot be timely optimized, and the air purification efficiency of the air conditioner is low due to the fact that the first preset time is too long can also be solved.
Further, referring to fig. 5, a fourth embodiment of the method for controlling an air conditioner according to the present invention is based on any one of the first to third embodiments, before the step S10, the method further includes:
and step S90, detecting the air humidity on the surface of the filter screen of the air conditioner when receiving the air purification instruction.
And S100, judging whether the air humidity on the surface of the filter screen is greater than preset humidity.
And when the air humidity on the surface of the filter screen is greater than the preset humidity, executing step S10, namely acquiring the power-on time of the air conditioner.
The user may power down the air conditioner for reasons other than cleaning the filter screen and then power up the air conditioner again. Therefore, the power-on time may not be the time between the installation of the filter screen into the indoor unit of the air conditioner and the receipt of the air purification command. Therefore, in order to accurately judge whether the filter screen is cleaned or not, when the air purification execution is received, the humidity detection device is adopted to detect the air humidity on the surface of the filter screen.
