Background
As users have made higher demands for indoor air quality, air conditioners and fresh air blowers carrying ionizers are becoming increasingly popular. The ionizer is widely used in the field of air purification, and the indoor air quality is optimized by generating negative ions and utilizing the characteristics of dust removal, dust fall, sterilization and disinfection of the negative ions. Currently, single electrode ionizers having only high voltage electrodes are used for the ionizer.
Currently, the emitter electrode of a single electrode ionizer is generally a negative voltage, and an electric discharge is usually formed between the emitter electrode and the grounded metal plate of the air treatment system to generate air ions. When the design is applied, a fixed distance is reserved between the transmitting electrode of the ionizer and the grounding metal plate, but the impedance between the transmitting electrode and the grounding metal plate can change along with the change of the ambient humidity.
When the ambient humidity is smaller, the impedance is increased due to the fixed distance between the emitting electrode of the ionizer and the grounding metal plate, so that the amount of ions generated by the ionizer is smaller. When the environmental humidity is larger, the impedance between the emitting electrode and the grounding metal plate is smaller, but the fixed distance between the emitting electrode and the grounding metal plate is still kept, the discharge energy of the emitting electrode is large, more ozone or other oxide ions are generated, and the environment is indirectly polluted.

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
The present application provides an air treatment system 100, the air treatment system 100 comprising an ionizer 1 capable of performing normal discharge in an environment with a large ambient humidity, and capable of realizing a self-cleaning function of the air treatment system.
An air treatment system 100 includes a housing, an ionizer 1, a grounded sheet metal 2, and a control system. An air outlet channel is formed in the shell, and air is blown into the room from the air outlet channel. The ion generator 1 is arranged in an air outlet channel formed in the shell, so that ions generated by the ion generator 1 can be diffused to an indoor space along with flowing wind in the air outlet channel, sterilization and disinfection of indoor air are realized, and the diffusion efficiency of the ions is quickened.
The ionizer 1 includes a power supply 11, and further includes a transmitting electrode 12 and a counter electrode 13 each connected to the power supply 11, the power supply 11 being capable of supplying electric power required for the transmitting electrode 12 and the counter electrode 13, the transmitting electrode 12 being capable of discharging with the counter electrode 13 in a grounded state or a reverse voltage state to generate ions.
The grounded metal plate 2 is grounded, and the emitter electrode 12 can discharge with the grounded metal plate 2 in the grounded state to generate ions. The counter electrode 13 is arranged between the grounding sheet metal 2 and the transmitting electrode 12, the distance between the grounding sheet metal 2 and the transmitting electrode 12 is larger than the distance between the counter electrode 13 and the transmitting electrode 12, the grounding sheet metal 2 is relatively far away from the transmitting electrode 12, and the counter electrode 13 is relatively nearer to the transmitting electrode 12.
The control system is connected with the ionizer 1, and can control the power supply 11 to supply or cut off power to the emitting electrode 12 and the counter electrode 13, and can also control the power supply 11 to supply different electric potentials to the emitting electrode 12 and the counter electrode 13.
The air treatment system 100 control method includes: the ion generator 1 starts a purifying function, and the control system detects the relative humidity value RH of the indoor environment; judging whether the indoor environment relative humidity RH meets a first threshold condition or not; if RH meets a first threshold condition, carrying out a working mode 1, supplying power to a transmitting electrode 12 by a power supply 11, and discharging between the transmitting electrode 12 and a grounding sheet metal 2; if RH does not meet the first threshold condition, and operating mode 2 is performed, power supply 11 supplies power to emitter electrode 12, and emitter electrode 12 and counter electrode 13 discharge.
Specifically, the control system detects the relative humidity value RH of the indoor environment, which refers to the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature. The air can absorb water vapor, when the indoor air absorbs more water vapor, the relative humidity value RH of the indoor environment becomes larger, and when the indoor air absorbs less water vapor, the relative humidity value RH of the indoor environment becomes smaller. The relative humidity value of the indoor environment can intuitively reflect the amount of absorbed water vapor in the air.
When the air absorbs more water vapor, the impedance between the emitter electrode 12 and the counter electrode 13 of the ionizer 1 decreases, and similarly, the impedance between the emitter electrode 12 and the ground sheet metal 2 decreases.
When the relative humidity RH of the indoor environment meets the first threshold condition, the air contains more water vapor, the impedance is smaller, the power supply 11 supplies power to the transmitting electrode 12, and the transmitting electrode 12 discharges with the grounding sheet metal 2 which is farther away from the transmitting electrode, compared with the prior art, the distance between the grounding sheet metal 2 and the transmitting electrode 12 is farther away, so that ozone or other oxides generated between the grounding sheet metal 2 and the transmitting electrode 12 can be reduced, and the environment is prevented from being polluted.
When the relative humidity RH of the indoor environment does not meet the first threshold condition, the air contains less water vapor, the impedance is larger, the power supply 11 supplies power to the emission electrode 12, the emission electrode 12 and the counter electrode 13 which is closer to the emission electrode 12 are performed, more ions can be generated due to the closer distance between the emission electrode 12 and the counter electrode 13, the larger impedance can be overcome, and the purpose of releasing the ions is achieved.
Because the emitter electrode 12 can discharge with the electrode 13 with a relatively close distance when the impedance is relatively high, the distance between the emitter electrode 12 and the grounding metal plate 2 is designed according to the application, the discharge condition of the grounding metal plate 2 and the emitter electrode 12 when the impedance is relatively high is not required to be considered, and only how to set the distance between the grounding metal plate 2 and the emitter electrode 12 when the impedance is relatively low is required to be considered. Therefore, compared with the prior art, the distance between the transmitting electrode 12 and the grounding metal plate 2 is farther, so that a large amount of ozone or oxide can be avoided, the normal running requirement of the ion generator 1 when the relative humidity RH of the indoor environment is larger can be met, the fact that the actual power of the power supply 11 of the ion generator 1 is larger than the rated power due to large discharge energy is avoided, the ion generator 1 is protected, and the stable running of the ion generator 1 is maintained. Meanwhile, when the impedance is larger, the application controls the emitter electrode 12 and the counter electrode 13 which are closer to each other to discharge, can overcome the larger impedance to generate enough ions, and can meet the requirement of normal operation of the ionizer 1 when the relative humidity RH of the indoor environment is smaller.
In some embodiments of the application, the first threshold condition is that RH reaches an upper limit value of a preset relative humidity value RH 1. The preset relative humidity value RH1 is set according to the performance parameters and the relative positions of the counter electrode 13, the emitter electrode 12 and the ground plate 2. When the relative humidity value RH of the indoor environment reaches the upper limit value of the preset relative humidity value RH1, the control system determines that the water vapor content in the air is high at this time, controls the emitter electrode 12 and the grounding metal plate 2 to perform long-distance discharge, and when the relative humidity value RH of the indoor environment reaches the lower limit value of the preset relative humidity value RH1, the control system determines that the water vapor content in the air is low at this time, and controls the emitter electrode 12 and the counter electrode 13 to perform short-distance discharge.
In some embodiments of the present application, the air treatment system 100 control method further comprises: if RH meets a first threshold condition, air treatment system 100 operates in mode 1; in the working mode 1, the power supply 11 continuously supplies power to the emitting electrode 12, the counter electrode 13 is in a suspended state, and ions are generated by discharging between the emitting electrode 12 and the grounding sheet metal 2.
Specifically, when the air treatment system 100 performs the operation mode 1, the power supply 11 continuously supplies power to the emission electrode 12, so that the emission electrode 12 is always in a state with electric potential, the counter electrode 13 is in a suspended state, the emission electrode 12 cannot discharge with the counter electrode 13, the emission electrode 12 can only perform long-distance discharge with the grounded metal plate 2, a large amount of ozone or oxide is avoided from being generated, environmental pollution is avoided, the actual running power of the power supply 11 of the ionizer 1 is always in the lower limit value of rated power, and voltage reduction of the emission electrode 12 is avoided.
In some embodiments of the present application, the air treatment system 100 control method further comprises: if RH does not meet the first threshold condition, air treatment system 100 operates in mode 2; in the working mode 2, the power supply 11 continuously supplies power to the emitting electrode 12, the counter electrode 13 is in a grounding state, and ions are generated by discharging between the emitting electrode 12 and the counter electrode 13.
Specifically, when the air treatment system 100 performs the operation mode 2, the power supply 11 continuously supplies power to the emitter electrode 12, so that the emitter electrode 12 is always in a state with electric potential, and the counter electrode 13 is in a grounded state, and since the distance between the emitter electrode 12 and the counter electrode 13 is smaller than the distance between the emitter electrode 12 and the grounded metal plate 2, the emitter electrode 12 can perform close-range discharge with the counter electrode 13 preferentially, a large amount of ions can be generated, and the problem of insufficient discharge of the ionizer 1 when the relative humidity of the indoor environment is low is avoided.
In some embodiments of the present application, the air treatment system 100 further comprises a blower in communication with the air outlet passage, the air outlet passage comprising an air outlet, the air treatment system 100 control method further comprising: judging whether the air processing system 100 receives a shutdown instruction, and if the air processing system 100 receives the shutdown instruction, controlling the air processing system 100 to perform the working mode 3; in the working mode 3, the air outlet is controlled to be closed, the blower is controlled to reversely rotate, the power supply 11 continuously supplies power to the emitting electrode 12, the counter electrode 13 is in a reverse voltage state, oxide is generated by discharging between the emitting electrode 12 and the counter electrode 13, and the oxide is reversely conveyed to the inside of the air treatment system 100 for purifying; when the counter electrode 13 is in the reverse voltage state, the voltage polarity of the counter electrode 13 is opposite to the voltage polarity of the emitter electrode 12.
Specifically, the blower provides a driving force required for the flow of air in the air outlet passage, and the air in the air outlet passage flows out from the air outlet into the room.
An air duct is formed in the housing of the air handling system 100, and includes an air outlet passage for delivering conditioned air. Bacteria tend to adhere to the inner walls and interior components of the air duct due to dust and bacteria carried in the air, which may be blown into the room along with the flow of the wind as the air treatment system 100 is used for a long period of time, affecting the health of indoor personnel. The control method of the air treatment system 100 can solve the problem of sterilizing and disinfecting the surfaces of the air duct and the internal parts of the air treatment system 100, and avoid health threat to human bodies caused by long-time use.
When the control system receives a shutdown instruction, the control system controls the air treatment system 100 to perform the working mode 3, and performs sterilization, disinfection and purification treatment on the internal components of the air treatment system 100. The control system controls the air outlet of the air outlet channel to be closed, so that the air treatment system 100 cannot exchange with the indoor environment. The blower is controlled to reversely rotate so that the blower drives wind to reversely flow. The power supply 11 continues to supply power to the emitter electrode 12, the emitter electrode 12 having an electrical potential at all times. The control power supply 11 outputs a voltage opposite to the emitter electrode 12 to the counter electrode 13, the counter electrode 13 is in a state of reverse voltage, the emitter electrode 12 and the counter electrode 13 are discharged, and the counter electrode 13 is in a state of reverse voltage, so that the emitter electrode 12 and the counter electrode 13 can discharge to generate a large amount of ozone or other oxides, and the ozone or other oxides are purified by using strong oxidizing property of the ozone or other oxides. Due to the reverse rotation of the blower, the wind flows in reverse and ozone or other oxides flow into the interior of the air treatment system 100 with the wind, effecting cleaning of the surfaces of the interior walls and interior components of the air treatment system 100.
In some embodiments of the present application, the blower maintains a minimum rotational speed for reverse rotation, so that the oxides are reversely and slowly transported inside the air treatment system 100, so that ozone or other oxides can fully contact the inner wall of the air duct and the surfaces of the inner components, thereby achieving the sterilization effect, the ozone or other oxides are easy to decompose at normal temperature, the ozone or other oxides can be decomposed during the slow transportation process, and environmental pollution caused by overflow of the ozone or other oxides is avoided.
In some embodiments of the present application, it is determined whether the operation time T of the operation mode 3 reaches the upper limit value of the preset time value T1, and if the operation time T reaches the upper limit value of the preset time value T1, the air treatment system 100 is controlled to be powered off.
Specifically, T1 is set to a time at which ozone or other oxides can sufficiently decontaminate the interior of the air treatment system 100 and most of the ozone or other oxides are decomposed, so that most of the ozone or other oxides are decomposed inside the air treatment system 100, reducing the amount of ozone or other oxides spilled.
In some embodiments of the present application, when air treatment system 100 is operating in mode 3, the voltage value of the reverse voltage is controlled to control the amount of ozone or other oxides produced, when the reverse voltage is high, the amount of ozone or other oxides produced is high, and when the reverse voltage is low, the amount of ozone or other oxides produced is low, and the effect of sterilizing the interior of air treatment system 100 is met by controlling the amount of ozone or other oxides produced, and a large amount of ozone or other oxides overflow caused by a large amount of ozone or other oxides is avoided.

An air outlet channel is formed in the shell and comprises an air outlet, and the ion generator 1 is arranged at the air outlet. The blower is communicated with the air outlet channel and is used for providing driving force for wind flow.
