Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

The embodiment 1 of the invention provides an electrostatic protection method which is applied to ionization purification equipment. The ionization purification apparatus includes an ionization device that generates an electrostatic field when discharged and a motor that operates to bring purified air out.

The electrostatic discharge protection method of embodiment 1 of the present invention will be described below by taking an ionization type air cleaner as an example. Fig. 1 is a schematic flow chart of an electrostatic protection method in embodiment 1 of the present invention, and as shown in fig. 1, the electrostatic protection method in embodiment 1 of the present invention includes the following steps:

s101: and acquiring the electrostatic value of the electrostatic field around the motor.

In embodiment 1 of the present invention, the ionization type air purifier performs purification by discharging between ionization type drawer plates, the motor is disposed above the ionization type drawer, and an electrostatic value around the motor can be obtained by the electrostatic induction device. For example, the static induction device may be disposed above an ionization drawer of the ionization air purifier and at the motor front end cap. When the drawer polar plate works, the discharge can be realized, an electrostatic field can be generated at the moment, and the electrostatic value released to the periphery of the motor is measured by the electrostatic induction device.

S102: and judging whether the static value is in a preset static interval or not.

In embodiment 1 of the present invention, the electrostatic section is divided by the intensity of the electrostatic value sensed by the electrostatic induction device, and when the intensity is fed back to the controller, the determination is performed by a program set by the controller.

As a further embodiment, before determining whether the static value is within a preset static interval, the method further includes: and acquiring the gear of the motor or the ionization and purification equipment, and determining the static interval according to the gear. That is, the electrostatic sections of the ionization air purifier are different when the ionization air purifier operates at different gears. Therefore, for the same static value at different gears, because the gears where the static value is located are different, and further the corresponding static intervals are different, different processing modes can be adopted for carrying out static protection, and the accuracy of the static protection is improved.

As another further embodiment, before determining whether the static value is within a preset static interval, the method further includes: and obtaining the running current of the motor or the ionization purification equipment, and determining the static interval according to the running current. That is, the electrostatic sections of the ionization type air cleaner are different when the ionization type air cleaner operates at different operating currents. Therefore, for the same static value when different running currents are used, the running currents corresponding to the static value are different, and then the corresponding static intervals are different, so that different processing modes can be adopted for carrying out static protection, and the accuracy of the static protection is improved.

In embodiment 1 of the present invention, the preset gear may be set by performing a plurality of tests on the principle that the performance of the ionization type air purifier is basically unchanged; the preset current value may be set by performing a plurality of tests on the principle that the performance of the ionization type air cleaner is not substantially changed.

S103: when the static value is within the static interval, reducing the power of the motor or reducing the power of the whole ionization purification device.

As a specific embodiment, the reducing the power of the motor or the reducing the power of the whole ionization purification device comprises: when the gear corresponding to the static interval is smaller than or equal to a preset gear, reducing the power of the motor; and when the gear corresponding to the static interval is greater than a preset gear, reducing the power of the ionization purification equipment.

As another specific embodiment, the reducing the power of the motor or the reducing the power of the whole ionization purification device comprises: obtaining the running current of the motor or the ionization purification equipment, and reducing the power of the motor when the running current is less than or equal to a preset current value; and when the operating current is greater than the preset current value, reducing the power of the ionization purification equipment.

Specifically, the three modes of reducing the voltage of the motor, reducing the current of the motor and simultaneously reducing the voltage and the current of the motor can be adopted for reducing the power of the motor, and in the practical application process, the voltage of the motor is not easy to change, so that the mode of reducing the current of the motor is adopted for reducing the power of the motor.

Specifically, the power of the ionization purification device can be reduced by reducing the voltage of the ionization purification device, reducing the current of the ionization purification device, and simultaneously reducing the voltage and the current of the ionization purification device.

In embodiment 1 of the present invention, the reduction value of the motor current may be set by performing a plurality of tests on the principle that the performance of the ionization type air purifier is substantially unchanged; the reduction value of the ionization purification apparatus current can be set by conducting a plurality of tests on the principle that the performance of the ionization air purifier is not substantially changed.

In embodiment 1 of the present invention, an electric field is generated during the operation of the motor, an electrostatic field is generated between the drawer electrode plates when the drawer electrode plates work, when the electrostatic field is too high, the electric field and the electrostatic field generate large electromagnetic interference, the electromagnetic interference affects the circuit of the motor, and when the work gear of the ionization air purifier is small, the power of the motor is reduced, that is, the electromagnetic interference between the electric field and the electrostatic field is reduced by reducing the electric field; when the working gear of the ionization type air purifier is large, the power of the ionization type air purifier is reduced, namely, the electromagnetic interference between an electric field and an electrostatic field is reduced by reducing a magnetic field.

The following are exemplified: for the lowest gear, when the rotating speed of the motor is between 300RPM and 500RPM, the whole machine performance is basically kept consistent except the influence of wind resistance of the filter screen. When the motor speed is reduced from 500RPM to 300RPM, the current of the motor is also reduced, and researches show that when the operating gear of the ionization type air purifier is smaller, the motor speed can be maintained between 300RPM and 500RPM even if the current of the motor is reduced, namely the performance of the ionization type air purifier is basically unchanged.

And for the highest gear, when the rotating speed of the motor is between 1600RPM and 1650RPM, the whole machine performance is basically consistent except the influence of wind resistance of the filter screen. When the rotating speed of the motor is reduced from 1650RPM to 1600RPM, the current of the motor is also reduced, and researches show that when the working gear of the ionization type air purifier is larger, the rotating speed of the motor can be maintained between 1600RPM and 1650RPM even if the current of the whole ionization type air purifier is reduced, namely the performance of the ionization type air purifier is basically unchanged.

As a further mode, the electrostatic protection method further includes: when the static value exceeds the static interval, opening the static shielding net; the electrostatic shielding net is arranged on the periphery of the motor and wraps the motor. That is to say, a layer of electrostatic shielding net is arranged on the surface of the motor and is grounded together with the whole motor, static electricity is led into the ground, and the electrostatic shielding net can effectively weaken the magnetic field formed by a static place and avoid the interference of the electrostatic shielding net on the stability of the magnetic field during the operation of the motor. For example, the electrostatic shielding net can be directly attached to the surface of the motor or attached to the motor mounting bracket, as long as the electrostatic shielding net can effectively operate.

The electrostatic shielding net is opened by inducing the static around the motor to reach the peak value through the electrostatic induction device, so that the electrostatic shielding net is opened, when the static value is in the static interval, the electrostatic field can be weakened by adjusting the magnitude of the supplied power piezoelectric current, the load of the whole machine is effectively reduced, and the load of the whole machine can be increased if the electrostatic shielding net and the whole machine are grounded in a shared mode.

It should be noted that, when the ionization type drawer of the ionization type air purifier discharges, a larger electrostatic field is formed, the static electricity easily collects dust, and the motor rotates to absorb the dust in the air, so that the dust is collected more easily and quickly. When dust accumulates to a certain amount, the drawer is not pulled open for cleaning, and the phenomena of arc discharge and ignition can occur in the humid environment and the discharge between the polar plates when the ionization type air purifier works. By adopting the electrostatic protection method of the embodiment 1 of the invention, the electrostatic field generated by discharging between the ionization type drawer pole plates can be reduced, so that the phenomena of arc discharge and ignition can be reduced.

To explain the electrostatic protection method of embodiment 1 of the present invention in more detail, a specific example is given. Fig. 2 is a schematic flow chart of an example of an electrostatic protection method according to embodiment 1 of the present invention, and as shown in fig. 2, the electrostatic protection method includes the following steps:

1. the static induction device is arranged on the surface of the motor, and when the static induction device induces that surrounding static electricity exceeds a certain value, the controller reduces input voltage and current. The static value of the whole machine is different between different gears when the whole machine runs, so that the static range is divided into intervals, one interval corresponds to one voltage and current, and when the range value of the interval is small, only the input voltage and the input current of the motor are controlled; when the interval range value is larger, the input voltage and current of the whole machine are controlled. Therefore, the operation efficiency of the air purifier is controlled, and the performance of the whole air purifier is not greatly deviated due to the reduction of voltage and current.

2. A layer of electrostatic shielding net is arranged on the surface of the motor and is grounded with the whole motor to guide static electricity to the ground. Opening the electrostatic shielding net requires the electrostatic induction device to induce the static around the motor to reach the peak value, so as to open the electrostatic shielding net. And the electrostatic shielding net can effectively weaken the magnetic field formed by the electrostatic field and avoid the magnetic field stability when the electrostatic shielding net interferes the operation of the motor.

3. The electrostatic shielding net can also effectively prevent dust collection and ignition caused by static electricity, and the electrostatic shielding net is designed into a detachable structure, so that the electrostatic shielding net is convenient to detach and clean.

In summary, the electrostatic protection method provided by the embodiment of the invention has the following technical effects:

1. the output of voltage and current is controlled by a static induction device arranged on the motor.

2. The voltage and current output of the motor are controlled, so that damage to the motor caused by static electricity is reduced.

3. A layer of electrostatic protection shielding net is arranged on the surface of the motor, so that a magnetic field formed by an electrostatic field is prevented from interfering with a magnetic field generated when the motor runs inside, and the motor does not run unstably due to magnetic field interference.

4. Prevent electrostatic precipitation and ignition, increase the use safety and prolong the service life of the motor.
