Referring to FIG. 1 , FIG. 2 and FIG. 13 , an air conditioner 200 according to an embodiment of the present invention includes an ion generator 201 . The control method of the air conditioner 200 includes:

S1, obtaining information on the presence or absence of the human body;

S2, obtaining the actual air quality in the room; and

S3, when the human body is present, the working voltage of the ion generator 201 is controlled according to the difference between the actual air quality and the set air quality, and the working voltage does not exceed the rated maximum voltage;

S4, controlling the ionizer 201 to operate at a rated maximum voltage when no human body is present.

The control method of the above embodiment can be executed by the control device 100. Specifically, the control device 100 according to the embodiment of the present invention is used to control the air conditioner 200. The control device 100 includes a first acquisition module 11, a second acquisition module 12, a first control module 13, and a second control module 14 for performing step S1, step S2, step S3, and step S4, respectively. That is to say, the first obtaining module 11 is configured to acquire the presence or absence information of the human body. The second acquisition module 12 is configured to acquire the actual air quality in the room. The first control module 13 is configured to control the operating voltage of the ionizer 201 according to the difference between the actual air quality and the set air quality when the human body is present, and the operating voltage does not exceed the rated maximum voltage. The second control module 14 is for controlling the operation of the ionizer 201 at the highest rated voltage when no human body is present. Among them, air quality can be assessed by the value of the air pollution index. Generally, the air pollution index can range from 0 to 500. When the value of the air pollution index is larger, the air quality is worse.

The first acquisition module 11 may include an infrared sensor, the infrared sensor is a heat detector, and the infrared sensor is used to detect the temperature level of the object and the temperature imaging shape, by comparing the detected temperature with the body temperature, and comparing the detected temperature imaging shape with The temperature of the human body is imaged to confirm whether the object is a human body.

The second acquisition module 12 may include an air quality sensor, and the second acquisition module 12 may be configured to detect a suspended particle content in the air, a content of a toxic and harmful gas, a charged particle content, a bacterial content, and the like.

Both the first control module 13 and the second control module 14 can be controllers or processors. The rated maximum voltage of the ionizer 201 can be the highest voltage value that can work normally. In some embodiments, the rated maximum voltage of the ion wind generator 201 can be determined according to the material, structure, process, etc. of the ion wind generator 201. The ion wind generator 201 can be calculated to obtain the highest rated voltage according to a large number of experiments or related formulas before leaving the factory. In one embodiment, the ion wind generator 201 has a rated maximum voltage of 50 kV and a rated minimum voltage of 5 kV, indicating that the ion wind generator 201 can operate normally when it is less than, equal to 50 kV and greater than or equal to 5 kV, and ion wind is higher than 50 kV. The generator 201 may be damaged, and the ion wind generator 201 cannot operate normally when it is less than 5 kV. The larger the operating voltage of the ionizer 201, the more the ionizer 201 ionizes the air and the more ozone generated and the higher the proportion of ozone in the ionized air, the stronger the bactericidal effect.

The air conditioner 200 is disposed indoors. When the human body is present in the room, the voltage of the ionizer 201 is less than the rated maximum voltage, so that the ionizer 201 is less ionized and the ozone is generated less and the proportion of ozone in the ionized air. Lower, and thus indoor ozone and ionized air are less harmful to the human body. When there is no human body in the room, the ion generator 201 operates at the rated maximum voltage, that is, the voltage of the ion generator 201 is equal to the rated maximum voltage. At this time, the amount of ionized air of the generator 201 is large and the generated ozone is large. And ozone accounts for a higher proportion of the ionized air, and then the indoor ozone and the ionized air sterilize the indoor air and other objects. The effect is better.

The control method and control device 100 of the air conditioner 200 according to the embodiment of the present invention can control the amount of the ion generator 201 to operate at the rated highest voltage to allow the ionizer 201 to ionize the air and the amount of generated ozone when there is no human body in the room. The sterilizing effect is good. When the human body exists in the room, the working voltage of the ion generator 201 is controlled to not exceed the rated maximum voltage to make the ionizer 201 ionize the air and the ozone generated is less harmful to the human body.

Referring to FIG. 3, FIG. 4 and FIG. 14, in some embodiments, the number of ion generators 201 includes a plurality, and in the presence of a human body, the ion generator 201 is controlled according to the difference between the actual air quality and the set air quality. The working voltage, the step of operating the voltage not exceeding the rated maximum voltage (ie, step S3) includes:

S31, when there is a human body, the plurality of ion generators 201 are controlled to operate at different or the same working voltage according to the difference between the actual air quality and the set air quality, and different or the same working voltage does not exceed the rated maximum voltage.

The control mode of the above embodiment may be performed by the control device 100. Specifically, the first control module 13 includes a first control submodule 132, and the first control submodule 132 may be configured to perform step S31. That is, the first control sub-module 132 is configured to control the plurality of ionizers 201 to operate at different or the same working voltage according to the difference between the actual air quality and the set air quality when the human body is present, different or the same work. The voltage does not exceed the rated maximum voltage.

When the number of ion generators 201 is plural, the first control sub-module 132 can be used to control the plurality of ionizers 201 to operate at different operating voltages according to the difference between the actual air quality and the set air quality, the different work. The voltage does not exceed the rated maximum voltage, and the different operating voltages may include an operating voltage having a voltage of zero. The first control sub-module 132 can also be configured to control the plurality of ionizers 201 to operate at the same operating voltage according to the difference between the actual air quality and the set air quality, the same operating voltage does not exceed the rated maximum voltage, and the same The operating voltages can all be zero or both greater than zero. The first control sub-module 132 can also be configured to control the plurality of ion generators 201 to operate at different operating voltages according to the difference between the actual air quality and the set air quality, and the different operating voltages do not exceed the rated maximum voltage. One of the operating voltages that are not identical may be zero and the other portion may be greater than zero.

Specifically, the plurality of ionizers 201 are installed at different positions, and thus the flow rate of the airflow generated by the air conditioner 200 flows through each of the ionizers 201 is different (that is, each unit flows (for example, 1 second). The air volume of the ionizer 201 is different). When the flow rate of the airflow through the ionizer 201 is large, the first control sub-module 132 can control the voltage of the ionizer 201 to be large, and the ionized particles and ozone in the air flowing through the ionizer 201 are relatively high. High, avoiding the ionized particles in the air and the low ozone content, resulting in poor air purification effect; when the flow rate of the airflow through the ionizer 201 is small, the first control sub-module 132 can control the ion generator 201 The voltage is small (even the voltage of the ionizer 201 can be controlled to be zero), and the ionized particles and ozone in the air flowing through the ionizer 201 are low, thereby avoiding high ozone content in the air. Ozone is more harmful to the human body.

Of course, the voltage of the plurality of ionizers 201 may also be any according to the interval between the plurality of ion generators 201, the interval between the two poles of each ion generator 201, and the corona value of each ion generator 201. One or more parameters control the voltage of each ion generator 201. For example, at the same operating voltage, when the interval between the two poles of the ionizer 201 is small, the ionizer 201 can ionize the amount of air and generate more ozone, and thus, the first control sub-module 132 can control The working voltage of the ionizer 201 is relatively small.

Referring to FIG. 5, FIG. 6, and FIG. 13, in some embodiments, the control method further includes:

S5, obtaining the actual humidity in the room;

When the human body is present, the operating voltage of the ion generator 201 is controlled according to the difference between the actual air quality and the set air quality, and the step of operating the voltage not exceeding the rated maximum voltage (ie, step S3) includes:

S32, controlling the working voltage of the ion generator 201 according to the difference between the actual humidity and the predetermined humidity, the difference between the actual air quality and the set air quality, and the working voltage does not exceed the rated maximum voltage.

The control mode of the above embodiment may be performed by the control device 100. Specifically, the control device 100 further includes a third obtaining module 15, the first control module 13 includes a second control submodule 134, and the third obtaining module 15 may be configured to perform steps. S5. The second control sub-module 134 is configured to perform step S32. That is, the third acquisition module 15 is used to acquire the actual humidity in the room. The second control sub-module 134 is configured to control the operating voltage of the ionizer 201 according to the difference between the actual humidity and the predetermined humidity, the difference between the actual air mass and the set air mass, and the operating voltage does not exceed the rated maximum voltage. Among them, the air humidity can be obtained by detecting the ratio of the vapor pressure of water in the air to the saturated vapor pressure of the water at the same temperature and pressure, that is, the air humidity can be the relative humidity of the air. Generally, the relative humidity of the air can range from 0% RH to 100% RH. When the value of the relative humidity of the air is larger, the humidity of the air is greater.

The third acquisition module 15 can include a humidity sensor. When the actual humidity in the room is small, the charged particles in the air are more likely to cause static discomfort to the user; when the actual humidity in the room is large, more charged particles in the air do not cause static discomfort to the user.

When the difference between the actual humidity in the room and the predetermined humidity is small (for example, the actual humidity is 45% RH, the predetermined humidity is 50% RH, the difference is -5% RH), and the difference between the actual air quality and the set air quality When the value is small (for example, the actual air mass is 80, the set air quality is 100, and the difference is -20), the second control sub-module 134 can control the operating voltage of the ionizer 201 to be the first working voltage, first The working voltage value is smaller than the previous working voltage (for example, the previous working voltage is 40KV, the first working voltage is 25KV), and the value of the first working voltage value is sufficient to satisfy the ion generator 201 in the first work. The amount of ionized air and the amount of ozone generated during voltage operation cause the actual air mass to be less than or equal to the set air quality, and to prevent the ion generator 201 from generating excessive charged ions to cause electrostatic discomfort to the user. When the actual air quality is much smaller than the set air quality (for example, the actual air mass is 40 and the air quality is set to 100), the first working voltage can also be 0V, that is, the ionizer 201 can be disabled. Avoid excessive charged ions to bring static discomfort to the user; when the actual air quality increases and gradually approaches the set air quality, the first working voltage is correspondingly increased from 0V (or the rated minimum voltage is 5KV). Large to ensure that the actual air quality is less than or equal to the set air quality, so that the user can always enjoy the cooling or heating of the air conditioner 200 in a clean air environment.

When the difference between the actual humidity in the room and the predetermined humidity is large (for example, the actual humidity is 55% RH, the predetermined humidity is 50% RH, the difference is 5% RH), and the difference between the actual air quality and the set air quality When the smaller (for example, the actual air mass is 80, the set air mass is 100, the difference is -20), the second control sub-module 134 can control the working voltage of the ionizer 201 to be the second working voltage, the second work. The voltage value is smaller than the previous operating voltage (for example, the previous operating voltage is 40KV, and the second operating voltage is 20KV), and the value of the second working voltage value is sufficient to satisfy the ion generator 201 at the second operating voltage. The amount of ionized air and the amount of ozone produced during operation make the actual air quality The amount is less than or equal to the set air quality. When the actual air quality is much smaller than the set air quality (for example, the actual air mass is 40, the set air mass is 100), the second working voltage can also be 0V, that is, the ionizer 201 can be disabled, and Avoid excessive charged ions to cause static discomfort to the user; when the actual air quality increases and gradually approaches the set air quality, the second working voltage is correspondingly increased from 0V (or the rated minimum voltage is 5KV). In order to ensure that the actual air quality is less than or equal to the set air quality, the user can always enjoy the cooling or heating of the air conditioner 200 in a clean air environment. The second operating voltage may be greater than, less than, or equal to the first operating voltage.

When the difference between the actual humidity in the room and the predetermined humidity is large (for example, the actual humidity is 55% RH, the predetermined humidity is 50% RH, the difference is 5% RH), and the difference between the actual air quality and the set air quality When the larger (for example, the actual air mass is 120, the set air mass is 100, the difference is 20), the second control sub-module 134 can control the working voltage of the ion generator 201 to be the third working voltage, and the third working voltage. The value is larger than the previous operating voltage (for example, the previous operating voltage is 20KV and the third operating voltage is 40KV), and the value of the third operating voltage value needs to satisfy the ionizer 201 when operating at the third operating voltage. The amount of ionized air and the amount of ozone produced can quickly reduce the actual air quality. When the difference between the actual air mass and the set air mass is larger, the third operating voltage is correspondingly larger to speed up the reduction of the actual air mass. The third operating voltage is generally greater than the first operating voltage and the second operating voltage.

When the difference between the actual humidity in the room and the predetermined humidity is small (for example, the actual humidity is 45% RH, the predetermined humidity is 50% RH, the difference is -5% RH), and the difference between the actual air quality and the set air quality When the value is large (for example, the actual air mass is 120, the set air quality is 100, and the difference is 20), the second control sub-module 134 can control the operating voltage of the ionizer 201 to be the fourth working voltage, and the fourth operation The voltage value is larger than the previous working voltage (for example, the previous working voltage is 25KV, and the fourth working voltage is 30KV), and the value of the fourth working voltage value needs to satisfy the ionizer 201 operating at the fourth working voltage. The amount of ionized air and the amount of ozone generated can quickly reduce the actual air quality and prevent the ion generator 201 from generating excessive charged ions to cause electrostatic discomfort to the user. When the difference between the actual air mass and the set air mass is larger, the fourth working voltage is correspondingly larger to speed up the reduction of the actual air quality, but the fourth working voltage is not too large to avoid the ion generator 201 being generated. Many charged ions bring static discomfort to the user. The fourth operating voltage is generally greater than the first operating voltage and the second operating voltage, and the fourth operating voltage is less than the third operating voltage.

In other embodiments, the third acquisition module 15 may further include a receiver and a humidity sensor, and the receiver may receive a control instruction of the user. When the difference between the actual humidity in the room and the predetermined humidity is small, for example, the actual humidity is 45% RH, the predetermined humidity is 50% RH, the difference is -5% RH) and the difference between the actual air quality and the set air quality is When the large (for example, the actual air mass is 120, the set air mass is 100, the difference is 20), the second control sub-module 134 can control the voltage of the ion generator 201 to select a suitable voltage to make the ion generator 201 It not only has the effect of sterilization and purification, but also avoids excessive charged ions to bring electrostatic discomfort to users.

Referring to FIG. 7 , FIG. 8 and FIG. 13 , in some embodiments, the air conditioner 200 further includes a fan 202, and the control method further includes:

S6, obtaining the actual temperature in the room;

S7, controlling the rotation speed of the fan 202 according to the difference between the actual air temperature and the set air temperature, and the difference between the actual air quality and the set air quality.

The control manner of the above embodiment may be performed by the control device 100. Specifically, the control device 100 further includes a fourth acquisition module. 16 and the third control module 17 can be used to perform step S6 and step S7, respectively. That is, the fourth acquisition module 16 is used to acquire the actual temperature in the room. The third control module 17 can be configured to control the rotational speed of the fan 202 based on a difference between the actual air temperature and the set air temperature, and a difference between the actual air mass and the set air mass.

The fourth acquisition module 16 can include a temperature sensor.

When the air conditioner 200 is in the heating state, if the difference between the actual air temperature in the room and the set air temperature is large (for example, the actual air temperature is 28 degrees, the set air temperature is 26 degrees, and the difference is 2 degrees) And when the difference between the actual air quality and the set air quality is small (for example, the actual air mass is 80, the set air quality is 100, and the difference is -20), the third control module 17 controls the fan 202 to rotate at the first speed. Rotating, the first rotational speed is smaller than the previous rotational speed (for example, the previous rotational speed is 250r/min, the first rotational speed is 200r/min), so that the unit time (for example, 1 second) passes through the air conditioner 200 and the ion generator 201. The air volume is reduced, on the one hand, the heating speed of the air conditioner 200 is lowered, thereby preventing the indoor temperature from rising too fast, and on the other hand, reducing the amount of ionized air and the amount of ozone generated, thereby avoiding excessive ozone damage to the human body. Generally, if the actual air mass is smaller, the first rotational speed is smaller than the previous rotational speed. Of course, the value of the first rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 202 operates at the first rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than the set air temperature.

When the air conditioner 200 is in the heating state, if the difference between the actual air temperature in the room and the set air temperature is large (for example, the actual air temperature is 28 degrees, the set air temperature is 26 degrees, and the difference is 2 degrees) And the third control module 17 controls the fan 202 to rotate at the second speed when the difference between the actual air quality and the set air quality is large (for example, the actual air mass is 120, the set air quality is 100, and the difference is 20). The second rotation speed is larger than the previous rotation speed (for example, the previous rotation speed is 250r/min, the first rotation speed is 280r/min), so that the unit time (for example, 1 second) passes through the air conditioner 200 and the ion generator 201. The amount of air increases, thereby increasing the amount of ionized air and the amount of ozone produced to increase the speed of air purification. Generally, if the actual air mass is larger, the second rotational speed is larger than the previous rotational speed, and the second rotational speed is generally greater than the first rotational speed. Of course, the value of the second rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 202 operates at the second rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than or equal to the set air temperature.

When the air conditioner 200 is in the heating state, if the difference between the actual air temperature in the room and the set air temperature is small (for example, the actual air temperature is 24 degrees, the set air temperature is 26 degrees, and the difference is -2 degrees). And the third control module 17 controls the fan 202 to be the third when the difference between the actual air quality and the set air quality is small (for example, the actual air mass is 80, the set air mass is 100, and the difference is -20) The rotation speed rotates, and the third rotation speed is larger than the previous rotation speed (for example, the previous rotation speed is 250r/min, and the third rotation speed is 280r/min), so that the air conditioner 200 and the ion generator pass through the unit time (for example, 1 second). The air volume of 201 is increased, thereby increasing the heating speed of the air conditioner 200, thereby increasing the actual air temperature. Generally, if the actual air temperature is smaller, the third rotational speed is larger than the previous rotational speed, and the third rotational speed is generally greater than the first rotational speed, and the third rotational speed may be greater than, less than, or equal to the second rotational speed. Of course, the value of the third rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 202 operates at the third rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than or equal to the set air temperature.

When the air conditioner 200 is in a heating state, if the difference between the actual air temperature in the room and the set air temperature is small (for example, the actual space is empty) The gas temperature is 24 degrees, the air temperature is set to 26 degrees, the difference is -2 degrees) and the difference between the actual air quality and the set air quality is large (for example, the actual air mass is 120 and the set air mass is 100). When the difference is 20), the third control module 17 controls the fan 202 to rotate at the fourth rotation speed, and the fourth rotation speed is larger than the previous rotation speed (for example, the previous rotation speed is 250r/min, and the fourth rotation speed is 280r/min. Increasing the amount of air passing through the air conditioner 200 and the ionizer 201 per unit time (for example, 1 second), thereby increasing the heating speed of the air conditioner 200, thereby increasing the actual air temperature, and increasing the amount of ionized air and The amount of ozone produced to increase the rate of air purification. Generally, if the actual air temperature is smaller or the actual air mass is larger, the fourth rotational speed is larger than the previous rotational speed, and the fourth rotational speed is generally greater than the second rotational speed and the third rotational speed. Of course, the value of the fourth rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 201 operates at the fourth rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than the set air temperature.

When the air conditioner 200 is in a cooling state, if the difference between the actual air temperature in the room and the set air temperature is large (for example, the actual air temperature is 28 degrees, the set air temperature is 26 degrees, the difference is 2 degrees) and When the difference between the actual air quality and the set air quality is small (for example, the actual air mass is 80, the set air mass is 100, and the difference is -20), the third control module 17 controls the fan 202 to rotate at the fifth speed. The fifth rotational speed is larger than the previous rotational speed (for example, the previous rotational speed is 250 r/min, and the fifth rotational speed is 280 r/min), so that the unit time (for example, 1 second) passes through the air conditioner 200 and the ion generator 201. The increase in the amount of air increases the cooling rate of the air conditioner 200, so that the indoor air can be cooled more quickly. Generally, if the actual air temperature is higher, the fifth rotational speed is larger than the previous rotational speed. Of course, the value of the fifth rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the wind generator 201 operates at the fifth rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is lower than the set air temperature.

When the air conditioner 200 is in a cooling state, if the difference between the actual air temperature in the room and the set air temperature is large (for example, the actual air temperature is 28 degrees, the set air temperature is 26 degrees, the difference is 2 degrees) and When the difference between the actual air quality and the set air quality is large (for example, the actual air mass is 120, the set air mass is 100, and the difference is 20), the third control module 17 controls the fan 202 to rotate at the sixth speed. The sixth rotational speed is larger than the previous rotational speed (for example, the previous rotational speed is 250r/min, and the sixth rotational speed is 300r/min), so that the air volume of the air conditioner 200 and the ionizer 201 is passed per unit time (for example, 1 second). The increase, on the one hand, accelerates the cooling rate of the air conditioner 200, thereby enabling rapid cooling of the room, and on the other hand, increasing the amount of ionized air and the amount of ozone generated to increase the speed of air purification. Generally, if the actual air mass is larger or the actual air temperature is higher, the sixth rotational speed is larger than the previous rotational speed, and the sixth rotational speed is generally greater than the fifth rotational speed. Of course, the value of the sixth rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 201 operates at the sixth rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than the set air temperature.

When the air conditioner 200 is in a cooling state, if the difference between the actual air temperature in the room and the set air temperature is small (for example, the actual air temperature is 24 degrees, the set air temperature is 26 degrees, and the difference is -2 degrees) And the third control module 17 controls the fan 202 to the seventh speed when the difference between the actual air quality and the set air quality is small (for example, the actual air mass is 80, the set air quality is 100, and the difference is -20). Rotation, the seventh rotation speed is smaller than the previous rotation speed (for example, the previous rotation speed is 250r/min, the seventh rotation speed is 200r/min), so that the unit time (for example, 1 second) passes through the air conditioner 200 and the ion generator 201. The air volume is reduced, on the one hand, the cooling speed of the air conditioner 200 is lowered, thereby preventing the indoor temperature from being lowered too fast, and on the other hand, reducing the amount of ionized air and the amount of ozone generated, thereby avoiding excessive ozone damage to the human body. General Ground, if the actual air temperature is smaller, the seventh rotational speed is smaller than the previous rotational speed, and the seventh rotational speed is generally smaller than the fifth rotational speed. Of course, the value of the seventh rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 201 operates at the seventh rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than the set air temperature.

When the air conditioner 200 is in a cooling state, if the difference between the actual air temperature in the room and the set air temperature is small (for example, the actual air temperature is 24 degrees, the set air temperature is 26 degrees, and the difference is -2 degrees) The third control module 17 controls the fan 202 to rotate at the eighth speed when the difference between the actual air quality and the set air quality is large (for example, the actual air mass is 120, the set air mass is 100, and the difference is 20). The eighth rotational speed is larger than the previous rotational speed (for example, the previous rotational speed is 250 r/min, and the eighth rotational speed is 280 r/min), so that the unit time (for example, 1 second) passes through the air conditioner 200 and the ion generator 201. The amount of air increases, thereby increasing the amount of ionized air and the amount of ozone produced to increase the speed of air purification. Generally, if the actual air mass is larger, the eighth rotational speed is larger than the previous rotational speed. Of course, the value of the fourth rotation speed can satisfy the amount of ionized air and the amount of ozone generated when the fan generator 201 operates at the fourth rotation speed, so that the actual air quality is less than or equal to the set air quality, and the actual air is also ensured. The temperature is higher than the set air temperature.

Specifically, step S8 may be performed after step S3 or step S4, or may be performed before step S1. The self-cleaning mode is a mode in which the air conditioner 200 is cleaned inside the air conditioner 200. When the ionizer 201 operates at the rated maximum voltage, the ionizer 201 can ionize more air and generate more ozone. If the air deflector 203 is closed, the ionized air and ozone of the ionizer 201 will not discharge the air conditioner. The outside of the device 200 flows to various corners of the air conditioner 200.

At this time, the process of flowing or diffusing the ionized air and the generated ozone to the inner corners of the air conditioner 200 is relatively not provided with the fan 202. The process of ionizing the air and generating ozone flowing or diffusing to various corners of the air conditioner 200 is faster; when the fan 202 is switched from the forward rotation 202 to the reverse rotation, the ionizer 201 ionizes the air and generates ozone toward the positive and negative In the opposite direction of the flow, the ionized air and the generated ozone flow or diffuse to the inner corners of the air conditioner 200, and the air and the generated ozone flow or diffuse to the air conditioner. The process of each corner of the device 200 is faster; when the fan 202 is switched from the forward rotation 202 to the reverse rotation, and then from the reverse rotation to the forward rotation, the ionized air and the generated ozone can flow or diffuse to the air conditioner more quickly. Each corner of the device 200.
