[0002] At present, the market of the air treatment equipment increasingly requires purification and sterilization functions. The electrostatic dust collection module and the negative ion module are the best selection devices for the air treatment equipment to realize purification and sterilization. The function of the electrostatic dust collection module is electrostatic dust collection, mainly used to reduce the PM2.5 value in the air. The function of the negative ion module is to eliminate odor, mainly used for sterilization and disinfection and to reduce the TVOC value. The cooperation of the above two modules makes the air treatment equipment realize efficient air purification function, thereby well meeting the needs of users.

[0003] The working principle of the electrostatic dust collection module and the negative ion module is that the tip with negative voltage (-15KV) in the high-voltage discharge module of the two modules discharges to GND (ground terminal), releases electrons into the air, and the free electrons are captured by oxygen, water, dust and other substances in the air to form negative ions.

[0004] If the air speed of the fan in the air treatment equipment is low, a large number of negative ions in the air treatment equipment are easily gathered, the conductivity of the air is changed, arc discharge of the high-voltage electrode and ozone and nitride are generated, and the risk of high-concentration ozone in the air treatment equipment is easily generated.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0024] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "linking" should be understood in a broad sense, for example, can be fixed connection, can be detachable connection, or integrally connected; can be mechanical connection; can be directly connected, or indirectly connected through intermediate medium; can be internal communication of two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] In the description of the present application, "and / or" is only a description of the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects have an "or" relationship.

[0026] The air treatment equipment with purification function includes a shell, a fan and a purification treatment device are installed in the shell, the fan draws air from the air inlet on the shell into the air duct of the shell, the air is treated by the purification treatment device, and then is guided out from the air outlet on the shell, so as to achieve the purpose of purifying air. Commonly used air treatment equipment includes air purifiers, air conditioners with purification function, etc.

[0027] Reference Figure 1 The air treatment equipment includes a shell with an air duct formed therein, and an electrostatic dust collecting device and a fan are installed in the air duct of the shell. The control method of the air treatment equipment in the embodiment of the present application includes the following steps:

[0028] When the PM2.5 value P m in the air is greater than or equal to a first preset PM2.5 value P m1 , and the rotating speed V of the fan is greater than or equal to a preset rotating speed V0, the electrostatic dust collecting device is controlled to be turned on. The shell air duct of the air treatment equipment is also provided with a detection device and a controller. The detection device can detect the PM2.5 value in the air, the rotating speed V of the fan can be obtained from the fan driving circuit, and the controller controls the electrostatic dust collecting device to be turned on or turned off.

[0029] When the PM2.5 value P m in the air is greater than or equal to a first preset PM2.5 value P m1When the fan speed V is less than the preset speed V0, the electrostatic precipitator is shut down (or kept shut down), and a fan malfunction indication message is issued. The air handling equipment also includes indicator lights or a display screen. The controller can control the indicator lights to display different colors or change the flashing pattern to indicate fan malfunctions, or the controller can control the display screen to directly display text or symbols indicating fan malfunctions.

[0030] When the PM2.5 value P in the air is detected m Less than the first preset PM2.5 value P m1 At that time, it will issue an indication that the air quality is good.

[0031] Compared to existing technologies, the control method of the air handling equipment in this embodiment of the invention, due to the detection of PM2.5 value P in the air... m Less than the first preset PM2.5 value P m1 When the PM2.5 level is detected, it indicates that there are fewer fine particulate matter in the air and the air quality is good. No purification treatment is needed, and the electrostatic precipitator should be turned off (or kept off) for energy saving. m Greater than or equal to the first preset PM2.5 value P m1 When the air quality is poor and purification is required, the fan speed V is measured. If V is greater than or equal to the preset speed V0, it indicates that the negative ions generated by the electrostatic precipitator are dispersed promptly, preventing excessive accumulation and the risk of high ozone concentration inside the air handling equipment. Therefore, the electrostatic precipitator is activated. Conversely, if V is less than the preset speed V0, it indicates that the negative ions generated by the electrostatic precipitator are prone to excessive accumulation, potentially leading to high ozone concentration inside the air handling equipment. In this case, the electrostatic precipitator is kept off, and a fan malfunction indicator is issued to remind the user to repair the air handling equipment promptly. Therefore, this control method avoids the problems of arc discharge at high-voltage electrodes and the generation of ozone and nitrogen oxides caused by activating the electrostatic precipitator, as well as the risk of high ozone concentration inside the air handling equipment.

[0032] Similarly, the air treatment equipment described above is also equipped with a negative ion generator inside its casing, as shown in the reference. Figure 2 The control method of this invention further includes:

[0033] When the TVOC value P in the air is detected oc Greater than or equal to the first preset TVOC value P oc1 Furthermore, when the fan speed V is greater than or equal to the preset speed V0, the negative ion generator is activated. The detection device in the aforementioned air handling equipment can also detect the TVOC value in the air, and the controller is also used to control the activation or deactivation of the negative ion generator.

[0034] When the TVOC value P in the air is detected oc Greater than or equal to the first preset TVOC value P oc1 When the fan speed V is less than the preset speed V0, the negative ion generator is kept off and a fan malfunction indication message is issued.

[0035] When the TVOC value P in the air is detected oc Less than the first preset TVOC value P oc1 When in use, turn off the negative ion generator (or keep it off).

[0036] Because the TVOC value P in the air was detected oc Less than the first preset TVOC value P oc1 When the concentration of volatile organic compounds (VOCs) in the air is low and the air quality is good, no purification treatment is needed, and the negative ion generator can be turned off, which is more energy-efficient; when the TVOC value P in the air is detected... oc Greater than or equal to the first preset TVOC value P oc1 When the air quality is poor and purification is required, the fan speed V is measured. If the fan speed V is greater than or equal to the preset speed V0, it indicates that the negative ions generated by the negative ion generator can be dispersed in time, and there is no risk of large-scale accumulation leading to high concentrations of ozone inside the air handling equipment. Therefore, the negative ion generator is turned on. If the fan speed V is less than the preset speed V0, it indicates that the negative ions generated by the negative ion generator are prone to large-scale accumulation, leading to high concentrations of ozone inside the air handling equipment. Therefore, the negative ion generator is turned off, and a fan malfunction indication message is issued to remind the user to repair the air handling equipment in time, so as to avoid the problem of arc discharge of high-voltage electrodes and generation of ozone and nitrogen oxides caused by starting the negative ion generator, as well as the risk of high concentrations of ozone inside the air handling equipment.

[0037] It should be noted that the preset speed of the aforementioned fan is determined by the fan blade structure, the air duct structure of the air handling equipment, the power of the electrostatic precipitator, the power of the negative ion generator, the distance between the negative high-voltage electrode and the GND electrode in the electrostatic precipitator and the negative ion generator, the ambient air humidity, and the installation position of the electrostatic precipitator and the negative ion generator. For example, the preset speed is 500 r / min.

[0038] In some embodiments, the control method further includes:

[0039] When the PM2.5 value P in the air is detected m Greater than or equal to the first preset PM2.5 value P m1When the fan speed V is less than the preset speed V0, the controller issues an indication message indicating poor air quality.

[0040] When the PM2.5 value P in the air is detected m Greater than or equal to the first preset PM2.5 value P m1 When the fan speed V is less than the preset speed V0, the controller issues an indication of poor air quality, reminding the user to take other actions to improve air quality (such as opening windows or turning on other air handling equipment). For example, the controller can control indicator lights to display different colors or change the flashing pattern to indicate changes in air quality, or the controller can control the display screen to directly display text or symbols indicating poor air quality.

[0041] Similarly, the above control methods also include:

[0042] When the TVOC value P in the air is detected oc Greater than or equal to the first preset TVOC value P oc1 When the fan speed V is less than the preset speed V0, the controller issues an indication message indicating poor air quality.

[0043] The TVOC value P in the air was detected. oc Greater than or equal to the first preset TVOC value P oc1 When the fan speed V is less than the preset speed V0, the controller issues an indication message indicating poor air quality, reminding the user to perform other operations to improve air quality (such as opening windows or turning on other air handling equipment).

[0044] Based on the above embodiments, the control method of the present invention further includes:

[0045] When the PM2.5 value P in the air is detected m Less than the first preset PM2.5 value P m1 Furthermore, the TVOC value P in the air was detected. oc Less than the first preset TVOC value P oc1 At that time, the system will issue an indication that the air quality is good.

[0046] Due to the PM2.5 value P in the air m Less than the first preset PM2.5 value P m1 Furthermore, the TVOC value P in the air was detected. oc Less than the first preset TVOC value P oc1 This indicates that the levels of particulate matter and volatile organic compounds in the air are low, and the air quality is good. At this time, the fan, electrostatic precipitator, and negative ion generator can all be shut down. The air handling unit only performs its detection function, resulting in lower energy consumption and extending the lifespan of the electrostatic precipitator and negative ion generator.

[0047] In some embodiments, the control method further comprises:

[0048] when the detected PM2.5 value P m is less than a second preset PM2.5 value P m2 , the electrostatic dust collection device is turned off. The second preset PM2.5 value P m2 is less than the first preset PM2.5 value P m1 .

[0049] Since the second preset PM2.5 value P m is less than the first preset PM2.5 value P m1 , the control method reduces the PM2.5 value in the air to a lower level before turning off the electrostatic dust collection device, ensuring better air quality treatment effect. The air treatment device further comprises a timer, and the determination of whether to turn off the electrostatic dust collection device is made when the cumulative time t1 recorded by the timer after the electrostatic dust collection device is turned on is greater than or equal to the preset time t0.

[0050] Similarly, in some embodiments, the control method further comprises:

[0051] when the detected TVOC value P oc is less than a second preset TVOC value P oc2 , the negative ion generating device is turned off. The second preset TVOC value is less than the first preset TVOC value.

[0052] Since the second preset TVOC value P oc2 is less than the first preset TVOC value P oc1 , the control method reduces the TVOC value in the air to a lower level before turning off the negative ion generating device, ensuring better air quality treatment effect. Similarly, the determination of whether to turn off the negative ion generating device is made when the cumulative time t2 recorded by the timer after the negative ion generating device is turned on is greater than or equal to the preset time t0.

[0053] The embodiment of the present application also comprises a control device for an air treatment device, the air treatment device comprising a shell with an air duct formed inside, and a static dust collecting device and a fan installed in the air duct of the shell, wherein the control device comprises a detection device and a controller, the detection device is installed in the air duct of the shell and used to detect the PM2.5 value of the air entering the air duct, and the controller is used to control the static dust collecting device to be turned on when the PM2.5 value of the air is greater than or equal to a first preset PM2.5 value and the rotating speed of the fan is greater than or equal to a preset rotating speed, control the static dust collecting device to be turned off and send an indication information of fan failure when the PM2.5 value of the air is greater than or equal to the first preset PM2.5 value and the rotating speed of the fan is less than the preset rotating speed, and control the static dust collecting device to be turned off when the PM2.5 value of the air is less than the first preset PM2.5 value.

[0054] The control device for the air treatment device of the embodiment of the present application can execute the control method of the air treatment device in the above-mentioned embodiment, and thus the same technical effects can be obtained, which will not be described herein again.

[0055] For example, the air treatment device of the above-mentioned embodiment further comprises a negative ion generating device installed in the air duct, the detection device is further used to detect the TVOC value of the air entering the air duct, and the controller is further used to control the negative ion generating device to be turned on when the TVOC value of the air is greater than or equal to a first preset TVOC value and the rotating speed of the fan is greater than or equal to a preset rotating speed, control the negative ion generating device to be turned off and send an indication information of fan failure when the TVOC value of the air is greater than or equal to the first preset TVOC value and the rotating speed of the fan is less than the preset rotating speed, and control the negative ion generating device to be turned off when the TVOC value of the air is less than the first preset TVOC value. The controller of the control device of the present embodiment controls the negative ion generating device to be turned on or turned off according to the TVOC value detected by the detection device and the rotating speed of the fan obtained from the fan driver, and can turn off the negative ion generating device when the rotating speed of the fan is less than the preset rotating speed, and send the indication information of fan failure to remind the user, thereby avoiding the risk of high concentration of ozone in the air treatment device caused by the large accumulation of negative ions when the negative ion generating device is turned on at a too low air speed.

[0056] In some embodiments, the detection device is a sensor integrated with a PM2.5 detection module and a TVOC detection module, which has high integration and is convenient to install. In other embodiments, the detection device comprises a PM2.5 detection device and a TVOC detection device. Of course, for the air treatment device, schemes for detecting the air temperature, air humidity or CO2 content of the air are also needed, and the detection device can be a sensor integrated with a temperature detection module, a humidity detection module, a CO2 content detection module, a PM2.5 detection module and a TVOC detection module.

[0058] The electrostatic dust collecting device can adopt a nano electrostatic dust collecting device or an IFD (Intense Field Dielectric) electrostatic dust collecting device. The IFD electrostatic dust collecting device refers to the use of a strong electric field of a dielectric material as a carrier for electrostatic dust removal. The power dielectric material forms a honeycomb-shaped hollow microchannel, and the dielectric wrapped electrode sheet forms a strong electric field in the channel, which exerts a huge attractive force on the charged particles in the air. It can adsorb almost 100% of the moving fine particles in the air while producing only minimal air flow resistance. The removal effect of PM2.5 and other particulate pollutants is particularly significant, and the dust removal effect is good and fast.

[0059] Based on the above-mentioned embodiment, the return air opening and the air outlet are formed on the shell, and the return air opening, the air outlet and the air duct are in communication. The detection device is installed in the shell and located at the return air opening. Compared with installing the detection device at the air outlet of the shell, the air volume at the return air opening is small, and less condensate water is generated, which facilitates installation.

[0060] The embodiment of the present application also includes a computer storage medium, which comprises instructions stored in the computer storage medium. When the instructions are executed, the control method of the air treatment device as described in the above-mentioned embodiment is realized.
