Referring to fig. 2, a first embodiment of a control method of an air conditioner according to the present invention includes:
and step S10, after receiving the air purification instruction, 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 the aggregation and sedimentation are attached to the filter screen and are separated outside the shell of the indoor unit of the air conditioner by the filter screen and fall off under the action of gravity, thereby achieving the effect of purifying the indoor air.
When a user sends an air purification instruction through a remote controller or triggers the air purification instruction through a display panel of the air conditioner, the air conditioner receives the air purification instruction, a controller of the air conditioner controls the operation of the negative ion purification device, negative ions are generated through the negative ion purification device, tiny particles such as dust and bacteria in the air are removed, the indoor air is purified, and the cleanliness of the indoor air is improved. In addition, in another embodiment of the present invention, when the air conditioner receives an air purification instruction, the air purification instruction is forwarded to a server corresponding to the air conditioner, and when the server receives an air purification request sent by the air conditioner, the server controls an anion purification device in the air conditioner to operate.
And step S20, detecting whether the negative ion purification device has a fault.
The method for detecting whether the negative ion purification device has faults comprises the steps of detecting the change condition of the negative ion concentration of the negative ion purification device in unit time within a certain range of space through the negative ion detection device, obtaining the quantity of negative ions generated by the negative ion purification device in unit time according to the change of the negative ion concentration, and judging that the negative ion purification device has faults when the quantity of the negative ions is smaller than a preset quantity; and when the quantity of the negative ions is greater than or equal to the preset quantity, judging that the negative ion purification device has no fault. The preset threshold value is the quantity of negative ions generated in unit time when the negative ion purification device of the model normally operates.
And step S30, stopping running the negative ion purification device when the negative ion purification device has a fault.
In the prior art, when an air conditioner with the negative ion purification device starts an air purification mode, a fault detection mechanism is not provided, and when the negative ion purification device breaks down, the negative ion purification device still continues to operate. The purification capacity of the anion purification device with faults is generally low, so that the air conditioner has poor dust removal effect and the indoor environment is improved slowly. And, the anion purifier continues to operate for a long time, the damage degree of the anion purifier is increased, the maintenance difficulty is increased, and the maintenance cost is increased. In the embodiment of the invention, when the fault of the negative ion purification device is detected, the negative ion purification device is controlled to stop running, so that the problem is avoided.
And step S40, after a preset time interval, returning to the step of controlling the operation of the negative ion purification device, wherein when the execution times of returning to execute the operation of the negative ion purification device is more than a preset threshold value, the step of controlling the operation of the negative ion purification device is stopped from returning to execute.
The main body of the anion purification device is an anion generator which consists of an external circuit and circuit components for generating high-voltage anions inside. When foreign matters such as water drops and winged insects fall into the external circuit, the abnormality occurs, so that the purification capacity of the negative ion purification device is reduced, and the pure fault of the negative ion purification device is detected. After the foreign matters are removed, the purifying capacity of the negative ion purifying device automatically recovers to be normal. When the purifying capacity of the negative ion purifying device is larger than the preset purifying capacity value, the situation that the current negative ion purifying device is normal is shown
Therefore, after the negative ion purification apparatus is detected to have a failure and stops operating, and a predetermined time interval elapses, the process returns to step S10, and the operation of the negative ion purification apparatus is controlled again to detect again whether the negative ion purification apparatus has a failure. If no fault is detected in the negative ion purification device, the operation of the negative ion purification device is not stopped, namely the negative ion purification device is controlled to operate according to the original purification program, and indoor air is optimized; and if the detected negative ion purification device still has a fault, stopping the operation of the negative ion purification device again. The negative ion purification apparatus is stopped for a preset time interval and then started again, whether a fault exists is detected, and the detection is repeatedly and circularly performed until the execution times of the step S10 is greater than a preset threshold value, and the step S10 is stopped being executed again. Through multiple detection, multiple detection results show that the negative ion purification device has faults, the negative ion purification device can be determined to have the faults which cannot be recovered by self, and the repeated circulating detection is meaningless, so that the negative ion purification device is not controlled to operate, and the damage to the air conditioner and the negative ion purification device caused by repeated operation is reduced.
The preset time interval and the preset threshold corresponding to the air conditioners with different models may be different, generally the preset time interval may be 5-10 minutes, and the preset threshold is not more than 5 times, and may be 3-5 times.
In this embodiment, when the air conditioner received the air purification instruction, control anion purifier operation, produce the anion through anion purifier, get rid of tiny particles such as dust, bacterium in the air, purify indoor air, improve indoor air's cleanliness factor. When the negative ion purification device starts to operate, whether the negative ion purification device has a fault or not is detected. And when the negative ion purification device is detected to have a fault, stopping running the negative ion purification device. And after the operation of the negative ion purification apparatus is stopped for a preset time interval, returning to step S10, controlling the operation of the negative ion purification apparatus again, and detecting whether the negative ion purification apparatus has a fault again. If no fault is detected in the negative ion purification device, the operation of the negative ion purification device is not stopped, namely the negative ion purification device is controlled to operate according to the original purification program, and indoor air is optimized; and if the detected negative ion purification device still has a fault, stopping the operation of the negative ion purification device again. The negative ion purification apparatus is stopped for a preset time interval and then started again, whether a fault exists is detected, and the detection is repeatedly and circularly performed until the execution times of the step S10 is greater than a preset threshold value, and the step S10 is stopped being executed again. The fault existence condition of the negative ion purification device is detected through limited circulation, the negative ion purification device can continuously operate after the fault is automatically eliminated, and the problem that the negative ion purification device continuously operates when the fault exists, so that the air conditioner is poor in dust removal effect and low in indoor environment improvement speed is avoided.
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, and after the step S30, the method further includes:
and step S50, acquiring the detection time consumed when the negative ion purification device runs until the negative ion purification device is detected to have a fault.
And recording the time consumed from the time when the negative ion purification device runs to the time when the negative ion purification device is detected to have a fault by adopting a timer, and recording the time as the detection time length.
And step S60, outputting the operation prompt information of the negative ion purification device when the detection duration is less than a first preset duration.
Because the anion purification device needs to be operated circularly, whether the fault still exists is detected, and the operation prompt information of the anion purification device is prevented from being repeatedly opened and closed in a short time, so that the user is confused. When the negative ion purification device has a fault and the operation of the negative ion purification device is stopped, the output of the operation prompt information of the negative ion purification device is not immediately stopped. Acquiring detection time from the time when the negative ion purification device starts to operate to the time when the negative ion purification device is detected to have faults, and continuously outputting operation prompt information of the negative ion purification device when the detection time is shorter than a first preset time; and when the detection duration is greater than or equal to the first preset duration, stopping outputting the operation prompt information along with the stop of the negative ion purification device. The first predetermined period of time should be small and may typically take a positive number of less than 1 minute.
The operation prompt information of the anion purification device comprises: the operation indicator lamp is lighted, and icons and other prompt messages corresponding to the negative ion purification device are displayed in the air conditioner remote controller or the display panel.
In the embodiment, the detection time from the start of the operation of the negative ion purification device to the detection of the fault of the negative ion purification device is obtained, and when the detection time is shorter than a first preset time, the operation prompt information of the negative ion purification device is continuously output; and when the detection duration is greater than or equal to the first preset duration, stopping outputting the operation prompt information of the negative ion purification device along with the stop of the negative ion purification device. The problem that a user is puzzled due to the fact that operation prompt information of the anion purification device is repeatedly turned on and off in a short time in the process that the anion purification device is circularly operated and whether faults still exist is solved.
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, and after the step S40, the method further includes:
step S70, when the operation prompt information of the negative ion purification device is being output, stopping outputting the operation prompt information;
and when the operation of the negative ion purification device is stopped to be executed and controlled, namely the negative ion purification device is not started, detecting whether the operation prompt information of the current negative ion purification device is output. Because the anion purification device is completely closed, the prompt message of the anion purification device does not need to be output. Therefore, when the operation prompt information of the anion purification device is being output, the output of the operation prompt information is stopped, so that the output of the operation prompt information is avoided, but the air conditioner does not carry out air purification and dust removal, so that the information output fault of the air conditioner is caused.
And step S80, outputting fault prompt information of the negative ion purification device.
Meanwhile, the fault of the negative ion purification device is detected for many times, the current fault that the negative ion purification device cannot be recovered by self is indicated, and fault prompt information is output, such as flashing of a display lamp, buzzing of a sound device, short prompt message sending to a bound mobile terminal and the like. The user is informed of the fault of the negative ion purification device through the fault prompt information, and the user is helped to maintain the negative ion purification device in time.
In addition, when the air conditioner receives operation instructions such as an air purification closing mode, an air conditioner running mode switching mode and an air conditioner shutdown instruction sent by a remote controller, the fault prompt information is cancelled, and the condition that the prompt information influences the life of a user is avoided (especially, when the prompt information is that a display lamp flickers or a buzzer sounds, light pollution or noise pollution is caused).
In the embodiment, after the operation of the negative ion purification device is stopped and returned to be controlled, namely the negative ion purification device is not started, whether the operation prompt information of the current negative ion purification device is output is detected. When the operation prompt information of the anion purification device is being output, the output of the operation prompt information is stopped, so that the output of the operation prompt information is avoided, but the air conditioner does not carry out air purification and dust removal, so that the information output fault of the air conditioner is caused. And after detecting that the negative ion purification device has faults, outputting fault prompt information, such as flashing of a display lamp, buzzing of a sound device, sending of a prompt short message to a bound mobile terminal and the like. The user is informed of the fault of the negative ion purification device through the fault prompt information, and the user is helped to maintain the negative ion purification device in time.
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:
step S90, when receiving an air purification instruction, acquiring the power-on time of the air conditioner;
and step S100, judging whether the power-on time length is greater than a second preset time length.
And when the power-on time length is greater than a second preset time length, executing step S10, namely controlling the operation of the negative ion purification device.
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 second 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 second 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 an air purification instruction, before controlling the operation of the negative ion purification device, the power-on time of the air conditioner is obtained. When the power-on time of the air conditioner is longer than the second preset time, the filter screen can be 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. 6, a fifth embodiment of the method for controlling an air conditioner according to the present invention is based on any one of the first to fourth embodiments, before the step S10, the method further includes:

The negative ion purifier has the working principle that high voltage direct current ionizes air molecules, more air negative ions can be gathered at an anode, more air positive and negative ions can be gathered at a cathode, electrodes are made into a multi-pole needle shape to increase the air ionization quantity, the formed positive and negative ions are adsorbed and neutralized by a negative part of a high voltage electric field in the purifier, and the formed negative ions are released and used for being condensed and settled with dust, bacteria and the like. Therefore, a large amount of negative ions with negative charges are generated in the operation process of the negative ion purification device, and if the front panel of the air conditioner is opened, a user easily touches the negative ion existing area to generate electric shock feeling. Although the current generated by the negative ion purification device is not so dangerous to the life of the user, the comfort of the user is still reduced, and the health of the user is damaged.
If the filter screen that indoor set return air inlet department of air conditioner set up is portable, through removing the filter screen, the filter screen that will gather a large amount of dust removes clean area, passes through the dust on the burnisher clearance filter screen such as brush in clean area, and the filter screen that the cleanness finishes resets. The filter screen resets to preset the position, and when the filter screen was in this preset the position, the filter screen can shelter from the return air inlet of air conditioning indoor set completely, and the dust of avoiding the anion to condense falls into the casing of air conditioning indoor set inside, blocks up the inside device of indoor set. After the filter screen is clean, the permeability of filter screen improves, and the return air resistance reduces, and the return air volume in the unit interval increases, is favorable to anion purifier to the purification of indoor air.
When the air conditioner purifies air, the indoor fan needs to rotate to drive the indoor air to enter the return air inlet, and negative ions generated by the negative ion purification device can be combined with positively charged particles such as dust, odor molecules, bacteria, smog and the like carried in the return air to be condensed and precipitated, so that the PM2.5 hazard is eliminated, and the effect of purifying the indoor air is achieved. Therefore, the negative ion purification device is operated, and meanwhile the negative ion purification device needs to be matched with the fan to rotate, so that the negative ions can be fully contacted with indoor air, and the dust removal effect is remarkably improved.
In conclusion, in order to guarantee the safety of users, the dust particles condensed by the negative ions are prevented from falling into the shell of the indoor unit of the air conditioner, and the dust removal effect of the air conditioner is improved. Before control anion purifier moves, detect the current state of air conditioner, when air conditioner current state satisfied the preset state, control anion purifier again and move, wherein, the preset state does the front panel of air conditioner be the closed condition the filter screen of air conditioner be in the preset position and the indoor fan rotational speed of air conditioner is not zero etc.. When the filter screen is located at the preset position, the filter screen completely shields the air return opening of the indoor unit.
