In the technical scheme of the invention, the air conditioner comprises an indoor air conditioner unit, the indoor air conditioner unit comprises a shell, and a heat exchanger and a cross-flow fan which are arranged in the shell, under the action of the cross-flow fan, air in an indoor space enters the shell through an air inlet on the shell, exchanges heat with the heat exchanger and then returns to the indoor space through an air outlet on the shell, and therefore the purpose of adjusting the temperature of the indoor space is achieved. The ozone device is arranged in the shell and is arranged between the heat exchanger and the cross-flow fan, so that under the action of the cross-flow fan, air in an indoor space is in full contact with the ozone device after exchanging heat with the heat exchanger, and ozone in the ozone device enters the air and is in full contact with the air, so that bacteria in the air can be better removed. And ozone can also enter the indoor space along with the air, removes the bacterium in the indoor space to improve the air quality of indoor space better.
The control method of the invention comprises the following steps: the method comprises the steps of obtaining a first relative humidity of an indoor space, obtaining the working state of the air conditioner if the first relative humidity is larger than a first preset value, and selectively controlling the ozone device to be started based on the working state of the air conditioner. Because the relative humidity of interior space is great when, breed a large amount of bacteriums easily, through such control mode to can open according to the operating condition selectivity control ozone device of air conditioner, utilize the ozone of ozone device release to get rid of the bacterium of interior space, thereby can improve the air quality of interior space more effectively, promote user experience.
If the air conditioner is in the working state, it indicates that a user may be in or ready to move in the indoor space where the air conditioner is located, and the indoor space has a sterilization requirement currently, at the moment, the ozone device is controlled to be started, and the ozone in the ozone device is used for removing bacteria in the indoor space, so that the aim of improving the air quality of the indoor space is fulfilled. After controlling the ozone device to be turned on for a first preset time, the bacteria in the indoor space are basically removed, and at the moment, the ozone device can be controlled to be turned off. Therefore, the purpose of sterilization can be achieved, and the situation that the ozone concentration in the indoor space is too high and the body health of people is influenced due to the fact that the ozone device is opened for too long time is avoided.
If the air conditioner is in a non-working state, whether a user is moving or is ready to move in the indoor space where the air conditioner is located is not well determined, whether the indoor space has a sterilization requirement is also not well determined, and at the moment, a prompt message of 'whether to start the ozone device' is sent, and then the ozone device is selectively controlled to be started according to the received feedback message.
Through such control mode, according to the present specific state of user, specific activity occasion, whether have the aspect such as degerming demand to control the ozone device and open or not open to can carry out the degerming to the indoor space with the mode that accords with user's actual demand more, thereby can effectively promote user experience.

If the received feedback information is 'yes', the situation that the sterilization requirement does exist currently is judged, at the moment, the ozone device is controlled to be started, and the ozone released by the ozone device is used for removing bacteria in the indoor space. When or after the ozone device is controlled to be opened, the cross flow fan is controlled to rotate reversely, air in the indoor space enters the shell through the air outlet in the shell under the action of the cross flow fan, and then the air is discharged from the air inlet in the shell after sequentially passing through the cross flow fan, the ozone device and the heat exchanger, so that when the air passes through the ozone device, the ozone in the ozone device can remove bacteria in the air, and part of the ozone enters the indoor space along with the air, and then the bacteria in the indoor space are removed. Therefore, the purpose of sterilization can be achieved, air cannot be blown to customers from the air outlet, and therefore user experience can be better improved.
Furthermore, when or after the cross flow fan is controlled to rotate reversely, the cross flow fan is controlled to operate in a mute mode, namely the cross flow fan is controlled to operate at a lower rotating speed, so that air circulation can be enhanced to achieve a better sterilization effect, and larger noise cannot be generated to influence the normal life of people.

Therefore, the purpose of sterilization can be achieved, and the situation that the ozone concentration in the indoor space is too high and the body health of people is influenced due to the fact that the ozone device is opened for too long time is avoided. After the ozone device is controlled to be turned off, the sterilization process is finished, at the moment, the user does not have the requirement of utilizing the air conditioner to adjust the air condition of the indoor space, at the moment, the cross flow fan is controlled to be turned off, and electric energy is saved.
Further, after the step of controlling the ozone device to be closed, the second relative humidity of the indoor space is obtained again, if the second relative humidity is larger than the second preset value, it indicates that the humidity of the indoor space is larger at the moment, bacteria are easy to generate, at the moment, the ozone device is controlled to be opened for a third preset time period every other preset time period, namely, the bacteria in the indoor space are removed by intermittently controlling the opening of the ozone device, meanwhile, the third preset time period is controlled by controlling the opening time period of the ozone device, so that the aim of removing bacteria can be achieved, the ozone concentration in the indoor space is prevented from being too high, and the user experience can be better improved.

It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. Although the present embodiment is described by taking a wall-mounted air conditioner as an example, the present invention can also be applied to indoor units of other types of air conditioners such as a ceiling type air conditioner and a cabinet type air conditioner.

After the air conditioner has been operated for a long time, especially when the humidity of the indoor space is high, a large amount of bacteria may grow in the air conditioner. Inside the casing of the indoor set of air current flow through air conditioner, can carry the bacterium to the interior space, and then lead to the air quality of interior space to descend, harm people's health when serious, user experience is relatively poor. Therefore, the invention provides a control method of an air conditioner, when the humidity of an indoor space is high, the ozone device is selectively controlled to be started according to the working state of the air conditioner, so that the air quality of the indoor space can be effectively improved, and the user experience is improved.
First, a wall-mounted air conditioner is taken as an example and a possible implementation manner of the ozone device of the present invention in the wall-mounted air conditioner is described with reference to fig. 1. Fig. 1 is a structural view of a wall-mounted type air conditioner according to an embodiment of the present invention.
As shown in fig. 1, the wall-mounted air conditioner includes an indoor unit of an air conditioner including a casing 1, and a heat exchanger 2 and a cross-flow fan 3 disposed inside the casing 1, the cross-flow fan 3 being distributed along a length direction of the heat exchanger 2. The casing 1 is provided with an air inlet and an air outlet, under the action of the cross flow fan 3, air in the indoor space enters the casing 1 through the air inlet, exchanges heat with the heat exchanger 2 and then returns to the indoor space through the air outlet, and therefore the purpose of adjusting the temperature of the indoor space is achieved. An ozone device 4 is arranged in the shell 1, and the ozone device 4 is arranged between the heat exchanger 2 and the cross-flow fan 3 in a screw joint, clamping connection and other modes. Therefore, under the action of the cross flow fan 3, the air in the indoor space is in full contact with the ozone device 4 after exchanging heat with the heat exchanger 2, and the ozone in the ozone device 4 enters the air and is in full contact with the air, so that bacteria in the air can be better removed. And ozone can also enter the indoor space along with the air, removes the bacterium in the indoor space to improve the air quality of indoor space better.
The ozone unit 4 has a substantially elongated configuration extending along the length of the heat exchanger 2 and having a length substantially similar to the length of the heat exchanger 2. The ozone device 4 arranged in this way can be connected with the air entering the shell 1 under the action of the cross flow fan 3 more fully, so that bacteria in the air can be removed better, and a better bacteria removing effect is obtained. Obviously, the length of the ozone device 4 may also be smaller than the length of the heat exchanger 2, and the ozone device is located near the left, near the right, or at a middle position between the heat exchanger 2 and the cross flow fan 3, and a person skilled in the art can flexibly select the specific shape, size, arrangement orientation, and the like of the ozone device 4 according to a specific application scenario, as long as the ozone device 4 is arranged between the heat exchanger 2 and the cross flow fan 3, and a good sterilization effect can be obtained.
In this embodiment, the wall-mounted air conditioner includes a control module, and the control module can receive the first relative humidity of the indoor space and selectively control the ozone device to be turned on according to the operating state of the air conditioner when the first relative humidity is greater than a first preset value.
In this embodiment, the wall-mounted air conditioner is configured with a humidity sensor, such as a resistive humidity sensor, a capacitive humidity sensor, an electronic humidity sensor, and the like. Taking a resistance-type humidity sensor as an example, the resistance-type humidity sensor measures the humidity according to the change of the resistivity and the resistance value of the humidity sensing film of the resistance-type humidity sensor when water vapor in the air is adsorbed on the humidity sensing film. The humidity sensor is connected with the control module, and transmits first relative humidity to the control module after detecting the first relative humidity in the indoor space.
It should be noted that the humidity sensor may be disposed at an air inlet of the wall-mounted air conditioner, or may be disposed at an outer side of one of two end covers located at two ends of the casing. Those skilled in the art can flexibly select the specific setting position of the humidity sensor according to the specific application scenario, as long as the relative humidity of the indoor space can be accurately obtained.
Of course, the wall-mounted air conditioner may not be provided with a humidity sensor, but may be in communication connection with a humidity sensor disposed at any position in the indoor space through bluetooth, a wide area network, a local area network, WiFi, a router for accessing WiFi + to the internet, ZIGBEE, NFC, GPRS, or the like, where the humidity sensor transmits data to the control module of the wall-mounted air conditioner after detecting the relative humidity of the indoor space.
It should be noted that only one humidity sensor may be provided, and the control module selectively controls the ozone device to be turned on according to the first relative humidity detected by the one humidity sensor. Obviously, a plurality of humidity sensors may be provided, and the plurality of humidity sensors respectively transmit the detected plurality of first relative humidities to the control module, and the control module calculates an average value of the plurality of first relative humidities and then selectively controls the ozone device to be turned on according to the average value of the first relative humidities. The number of humidity sensors can be chosen flexibly by those skilled in the art according to the specific application, as long as the first relative humidity can be obtained accurately.
In this embodiment, the ozone device may be a device storing ozone, and after the control module controls the ozone device to be turned on, the stored ozone is released to the outside of the ozone device, and when air flows through the ozone device, the ozone can enter the air.
Obviously, the ozone device may also be a device capable of generating ozone, and after the control module controls the ozone device to be turned on, the ozone device starts generating ozone and releases the generated ozone into the air flowing through the ozone device. For example, ozone is generated by an ultraviolet irradiation method: the dried oxygen gas is irradiated with ultraviolet rays to activate a part of oxygen molecules to be understood as oxygen atoms, thereby forming ozone. As another example, ozone is generated by an electrolytic process: the water is electrolyzed by low-voltage direct current to generate ozone by oxidation reaction on the anode-solution interface. As another example, ozone is generated by a radiochemical process: ozone is generated by dissociating oxygen molecules using various radioactive sources. As another example, ozone is generated by a dielectric barrier discharge method: free high-energy electrons in corona are generated in the air by an alternating high-voltage electric field to dissociate oxygen molecules, and the oxygen molecules are polymerized into ozone molecules by collision.
Of course, the skilled person can flexibly select the specific arrangement form of the ozone device according to the specific application scenario, as long as the ozone device can release ozone outwards after the ozone device is controlled to be turned on.
A control method of the air conditioner of the present invention will be explained with reference to fig. 2 to 4.
As shown in fig. 2, in one possible embodiment, the control method of the present invention includes:
step S100: acquiring a first relative humidity of an indoor space;
step S200: if the first relative humidity is larger than a first preset value, acquiring the working state of the wall-mounted air conditioner;
step S300: selectively controlling the ozone device to be turned on based on the working state of the wall-mounted air conditioner.
In step S100, a first relative humidity in an indoor space where the wall-mounted air conditioner is located is obtained based on the humidity sensor.
Step S200: comparing the first relative humidity obtained in step S100 with the first preset value, if the first relative humidity is greater than the first preset value, for example, the first relative humidity is 85%, and the first preset value is 70%. This indicates that the relative humidity of the indoor space is high and bacteria are likely to grow. At this time, the working state of the wall-mounted air conditioner is obtained, that is, whether the wall-mounted air conditioner is currently in the working state or in the non-working state is obtained.
It is obvious that the specific values of the first relative humidity and the first preset value described above are only an exemplary description and those skilled in the art should not understand the limitations thereof.
In step S300: and selectively controlling the ozone device to be started based on the working state of the wall-mounted air conditioner acquired in the step S200.
Through such control mode to can selectively control the ozone device according to the operating condition of air conditioner and open, utilize the ozone of ozone device release to remove the bacterium of interior space, thereby can improve the air quality of interior space more effectively, promote user experience.
As shown in fig. 3, in a possible embodiment, the control method of the present invention further includes:
step S200: if the first relative humidity is larger than a first preset value, acquiring the working state of the wall-mounted air conditioner;
step S410: judging whether the wall-mounted air conditioner is in a working state, if so, executing the step S310; if not, executing step S330;
step S310: controlling the ozone device to be started;
step S320: after controlling the ozone device to be started for a first preset time, controlling the ozone device to be closed;
step S330: sending prompt information of whether to start the ozone device;
step S340: and selectively controlling the ozone device to be started according to the received feedback information.
In step S410, based on the working load of the wall-mounted air conditioner obtained in step S200, it is determined whether the wall-mounted air conditioner is in a working state, if so, it indicates that there may be a user who is in or about to move in the indoor space where the air conditioner is located, and the indoor space currently has a sterilization requirement, at this time, the ozone device is controlled to be turned on, and step S310 is executed. The ozone released by the ozone device is used for removing bacteria in the indoor space, thereby achieving the purpose of improving the air quality of the indoor space.
In step S320, after controlling the ozone device to be turned on, i.e., after step S310, the ozone device releases ozone into the air, removes bacteria in the air, and enters the indoor space together with the air to further remove the bacteria in the indoor space. After the ozone device is turned on for a first preset time period, for example, the first preset time period is 10min, that is, after the first preset time period of step S310 is executed, the concentration of ozone in the indoor space is already high, and if the concentration of ozone in the indoor space continues to increase, even to the highest concentration level, the health of the user may be affected, at this time, the ozone device is controlled to be turned off, that is, step S320 is executed. In this embodiment, the maximum concentration level of ozone is a concentration at which the concentration of ozone in the air affects the body of the user.
Through the control mode, the aim of sterilization can be achieved, and the situation that the body health of people is influenced due to overhigh ozone concentration in the indoor space caused by overlong opening time of the ozone device is avoided, namely the body health of a user is ensured.
It should be noted that after the ozone device is controlled to be turned on, the ozone device can release ozone to the indoor space in a pulse mode, that is, a certain amount of ozone is released to the indoor space each time, and the purpose of sterilization is achieved through a mode of multiple quantitative release. Obviously, after the ozone device is controlled to be turned on, the ozone device can not be turned off, and the ozone concentration in the indoor space can be ensured to be always lower than the highest concentration level by reducing the speed of ozone released by the ozone device and the like.
It should be noted that, when it is acquired in step S200 that the wall-mounted air conditioner is in the operating state, the ozone device may not be immediately controlled to be turned on, but a prompt message of "whether to turn on the ozone device" may be sent first, and then the ozone device may be controlled to be turned on or not turned on according to the feedback of the user. A person skilled in the art can flexibly select a specific control mode for controlling the ozone device when the wall-mounted air conditioner is in the working state according to a specific application scene as long as the method can effectively remove bacteria in the indoor space and improve the air quality of the indoor space.
If not, it is determined that it is not very certain whether the user is moving or preparing to move in the indoor space where the air conditioner is located, and it is also not very certain whether the indoor space has a sterilization requirement, at this time, a prompt message of "whether to turn on the ozone device" is sent, and step S330 is executed.
In step S340, after the prompt message of "whether to turn on the ozone device" is sent, that is, after step S330, the ozone device is selectively controlled to turn on according to the received feedback message.
Through such control mode, can start or not start the ozone device according to user's wish to can get rid of the bacterium of indoor space better, promote user experience.
The prompt message of "whether to turn on the ozone device" may be sent to the user by voice, text, or voice + text, or by combining the above modes with light or alarm. For example, the prompt information is sent to the user in a voice mode, the wall-mounted air conditioner comprises a loudspeaker and other playing modules used for playing voice and a pickup module used for collecting feedback information, the prompt information is directly used for reminding the user in the voice mode through the loudspeaker and other playing modules, the user gives the feedback information in the voice mode, and the pickup module such as a microphone collects the feedback information and transmits the feedback information to the control module. Of course, the prompt message may also be directly sent to a mobile terminal such as a remote controller, a mobile phone, and a tablet pc, which communicates with the wall-mounted air conditioner, and the user returns the feedback message through the mobile terminal. Those skilled in the art can flexibly select a sending object and a sending mode of the prompt information and a specific mode of returning the feedback information according to a specific application scene as long as a user can know the prompt information and return the feedback information.
Through above-mentioned control mode, also can control the ozone device according to aspects such as the current specific state of user, specific activity occasion, whether have degerming demand to open or not to can carry out the degerming to the interior space with the mode that accords with user's actual demand more, thereby can effectively promote user experience.
As shown in fig. 4, in one possible embodiment, "selectively controlling the ozone device to be turned on according to the received feedback information" specifically includes:
step S330: if the wall-mounted air conditioner is in a non-working state, sending prompt information of 'whether to start an ozone device';
step S341: judging whether the received feedback information is 'yes', if not, executing step S342; if yes, go to step S343;
step S342: the ozone device is not started;
step S343: controlling the ozone device to be started;
step S344: controlling the reverse rotation of the cross flow fan;
step S345: the crossflow fan is controlled to operate in a silent mode.
In step S341, after the prompt message of "whether to turn on the ozone device" is sent in step S330, the user gives feedback information based on his/her actual needs after receiving the prompt message. At this time, it is determined whether the received feedback information is yes, if not, it indicates that there is no sterilization requirement, and at this time, the ozone device is not turned on, and step S342 is executed.
If yes, it indicates that there is a need for sterilization, and at this time, the ozone device is controlled to be turned on, that is, step S343 is executed to remove bacteria in the indoor space by using the ozone released by the ozone device.
In step S344, after the ozone device is controlled to be turned on, the cross flow fan is controlled to rotate in a reverse direction, air in the indoor space enters the casing through the air outlet on the casing under the action of the cross flow fan, and is discharged from the air inlet on the casing after sequentially passing through the cross flow fan, the ozone device and the heat exchanger, so that when the air passes through the ozone device, ozone in the ozone device can remove bacteria in the air, and part of the ozone enters the indoor space along with the air, thereby removing the bacteria in the indoor space. Therefore, the purpose of sterilization can be achieved, air cannot be blown to customers from the air outlet, and therefore user experience can be better improved.
It should be noted that the ozone device may be controlled to be turned on and the crossflow fan may be controlled to be turned reversely, that is, step S343 and step S344 may be executed simultaneously. The opening time of the cross flow fan can be flexibly selected by a person skilled in the art according to a specific application scene, as long as the purpose of sterilization can be achieved.
Of course, after the ozone device is controlled to be started, the cross flow fan can be controlled not to rotate reversely but to rotate forwards, and a person skilled in the art can flexibly select the cross flow fan according to a specific application scene.
In step S345, the crossflow fan is controlled to operate in the silent mode while the crossflow fan is controlled to rotate in reverse, that is, step S344 is operated simultaneously with step S345. That is, the crossflow fan is controlled to operate at a low rotational speed such as 650r/min or the like at the beginning of turning on the crossflow fan, so that noise generated when the crossflow fan operates is small. Therefore, the air circulation can be enhanced, a good sterilization effect is achieved, and large noise cannot be generated to influence the normal life of people.
It is obvious that 650r/min is only an exemplary description of the rotational speed of the cross flow fan when operating in the silent mode, and those skilled in the art can specifically determine the specific value of the rotational speed of the cross flow fan according to the specific model of the air conditioner, the power of the cross flow fan, etc., as long as it can ensure that the cross flow fan operates in the silent mode.
It should be noted that, after the crossflow fan is controlled to rotate reversely, the crossflow fan may be controlled to operate in the silent mode, that is, step S344 is executed first and then step S345 is executed. After the cross-flow fan is controlled to be started, the cross-flow fan is controlled to operate at a slightly higher rotating speed, such as 850r/min, and then the cross-flow fan is controlled to operate in a mute mode, and the cross-flow fan can be flexibly selected by a person skilled in the art according to a specific application scene.
In a possible embodiment, after performing step S343, the control method of the present invention further includes:
after the ozone device is controlled to be started for a second preset time, the ozone device is controlled to be closed;
after the ozone device is controlled to be closed, the cross-flow fan is controlled to be closed.
After the ozone device is controlled to be started, the ozone device releases ozone into the air, bacteria in the air are removed, and the ozone enters the indoor space along with the air, so that the bacteria in the indoor space are further removed. After the ozone device is turned on for a second preset time period, if the second preset time period is 10min, that is, after the second preset time period of the step S343 is executed, the concentration of ozone in the indoor space is already high and reaches the highest concentration level, if the concentration of ozone in the indoor space continues to increase, the health of the user may be affected, and at this time, the ozone device is controlled to be turned off. Through the control mode, the aim of sterilization can be achieved, and the situation that the ozone concentration in the indoor space is too high and the body health of people is influenced due to the fact that the ozone device is turned on for too long time is avoided.
It should be noted that after the ozone device is controlled to be turned on, the ozone device can release ozone to the indoor space in a pulse mode, that is, a certain amount of ozone is released to the indoor space each time, and the purpose of sterilization is achieved through a mode of multiple quantitative release. Obviously, after the ozone device is controlled to be turned on, the ozone device can also not be turned off, and the ozone concentration in the indoor space can be ensured to be lower than the highest concentration level by reducing the speed of ozone released by the ozone device and the like.
After the ozone device is controlled to be turned off, the sterilization process is finished, at the moment, the user does not have the requirement of utilizing the air conditioner to adjust the air condition of the indoor space, at the moment, the cross flow fan is controlled to be turned off, and electric energy is saved.
After the ozone device is controlled to be turned off, the cross flow fan may be controlled to rotate forward without turning off the cross flow fan, and the air circulation in the indoor space may be enhanced by the cross flow fan. Of course, before controlling the cross flow fan to rotate forward, prompt information of whether to control the cross flow fan to rotate forward may be sent first, and then whether to control the cross flow fan to rotate forward may be determined according to the received feedback information. Those skilled in the art can flexibly select the application according to specific application scenarios.
After the ozone device is controlled to be started for the first preset time period or after the ozone device is controlled to be started for the second preset time period, the bacteria in the indoor space are basically removed. Therefore, the oxygen generating device is closed after the ozone device is opened for a first preset time period, and the oxygen generating device is closed after the ozone device is opened for a second preset time period.
In one possible embodiment, the control method of the present invention further comprises:
acquiring a second relative humidity of the indoor space again after the step of controlling the ozone device to be turned off;
and if the second relative humidity is greater than a second preset value, controlling the ozone device to be started for a third preset time period every other preset time period.
After the ozone control device is turned off, the indoor space can grow bacteria again along with the time, and particularly when the humidity of the indoor space is high, the bacteria are easy to grow. In this way, in order to ensure the air quality of the indoor space, after the ozone control device is turned off, the second relative humidity of the indoor space is acquired again by using the humidity sensor. The second relative humidity is then compared to a second preset value, if the second relative humidity is greater than the second preset value, e.g., the second relative humidity is 80% and the second preset value is 70%. Therefore, the relative humidity of the indoor space is high, and bacteria are easy to breed. At this time, the ozone device is controlled to be started for a third preset time period every other preset time period, and if the preset time period is 3 hours, the third preset time period is 10 minutes. That is, if the second relative humidity of the indoor space is greater than 70%, the ozone device is controlled to be activated every 3 hours for 10 minutes each time.
It is obvious that the specific values of the second relative humidity and the second preset value described above are only an exemplary description and those skilled in the art should not understand the limitations thereof.
Obviously, the preset time period may also be other values, such as shorter time of 2.5 hours, 2 hours, etc. or longer time of 3.5 hours, 4 hours, etc., and those skilled in the art may flexibly select a specific value of the preset time period according to a specific application scenario as long as the sterilization effect of the indoor space can be ensured.
Like this through the bacterium of intermittent control ozone device opening and getting rid of the interior space, it is long for the third is preset long when opening through control ozone device simultaneously to can avoid the ozone concentration of interior space too high when reaching the purpose of degerming, thereby can promote user experience better.
It should be noted that, instead of obtaining the second relative humidity of the indoor space again, the ozone device may be directly controlled to be turned on for a third preset time period every other preset time period after the ozone device is controlled to be turned off.
It should be noted that the specific values of the first preset time period, the second preset time period, and the third preset time period are only described as an example, and those skilled in the art can flexibly select the values according to specific application scenarios as long as a better sterilization effect can be obtained after the ozone device is turned on for the first preset time period, or after the second preset time period, or after the third preset time period.
In summary, in the preferred technical solution of the present invention, when the first relative humidity of the indoor space is greater than the first preset value, the working state of the air conditioner is obtained, and then the ozone device is selectively controlled to be turned on based on the working state of the air conditioner, so that the air quality of the indoor space can be more effectively improved, and the user experience is improved. And if the air conditioner is in a working state, controlling the ozone device to be started, and after the ozone device is started for a first preset time, closing the ozone device. If the air conditioner is in a non-working state, sending prompt information of 'whether to start the ozone device', and then selectively controlling the ozone device to start according to the received feedback information. Through such control mode to can control the ozone device according to the present specific state of user, specific activity occasion, whether have the aspect such as degerming demand to open or not open, thereby can carry out the degerming to the interior space with the mode that accords with user's actual demand more, and can make the ozone concentration in the interior space be less than the highest concentration level, can not influence people's healthy, thereby can promote user experience more effectively. After the ozone device is closed, if the second relative humidity of the indoor space is greater than the second preset value, the ozone device is started for a third preset time period every other preset time period, so that bacteria in the indoor space can be better removed, and the user experience is better improved.
