Detailed Description

To make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a blowing assembly, which comprises a wind channel, a fan 4 and an electrostatic dust collector 1. The electrostatic precipitator 1 comprises an electrostatic source, a corona electrode 2 and a dust collecting electrode 3. The corona electrode 2 is connected with the negative pole of the static electricity source, the dust collecting electrode 3 is connected with the positive pole of the static electricity source, the corona electrode 2 can ionize air to generate negative charges, and the dust collecting electrode 3 can adsorb dust with the negative charges. The fan 4 is arranged in the air duct, the corona electrode 2 is arranged in the air duct, and the dust collecting electrode 3 is arranged in the air duct and is arranged at the air outlet side of the fan 4.

It is worth mentioning that there is a certain spatial separation between the corona electrode 2 and the dust collecting electrode 3.

When the electrostatic dust collector 1 works, under the action of a non-uniform electric field around the corona electrode 2, air around the corona electrode 2 is ionized, so that negative charges are generated. Particles such as dust and dirt near the corona electrode 2 are bonded to the negative charges to generate negatively charged dust. It can be understood that the negatively charged dust has a tendency to move toward the dust collecting electrode 3, and can be adsorbed by the dust collecting electrode 3.

Because the fan 4, the corona electrode 2 and the dust collecting electrode 3 are all arranged in the air channel, when the fan 4 rotates, air in the air channel circulates, and negative charges near the corona electrode 2 can be diffused into the space of the whole air channel and combined with dust in the space of the whole air channel.

Moreover, because the dust collecting electrode 3 is arranged at the air outlet side of the fan 4, the dust with negative charges diffused in the whole air channel can flow to the dust collecting electrode 3 along with the rotation of the fan 4 and is adsorbed on the dust collecting electrode 3, so as to achieve the purpose of dust collection.

Wherein, the dust collecting electrode 3 is arranged at the air outlet side of the fan 4 and can comprise various arrangement modes. For example, in one embodiment, the fan 4 is a centrifugal fan that blows air in multiple directions along the radial direction, and the dust collecting electrode 3 can be disposed at any position along the radial direction of the centrifugal fan.

Alternatively, in another embodiment, the fan 4 is an axial flow fan, and the dust collecting electrode 3 may be provided at an axial position of the axial flow fan.

The corona electrode 2 may be installed at other positions in the air duct, or may be installed at a certain air outlet side of the fan 4. For example, in one embodiment, as shown in fig. 1, the fan 4 is a centrifugal fan, and the air outlet side of the fan 4 is the radial position of the fan 4. The corona electrode 2 and the dust collecting electrode 3 are both arranged at the same side of the fan 4 at the radial position.

In another embodiment, the fan 4 is a centrifugal fan, the corona electrode 2 and the dust collecting electrode 3 are both disposed at radial positions of the fan 4, and the corona electrode 2 and the dust collecting electrode 3 are disposed at both sides of the fan 4.

In another embodiment, the fan 4 is an axial fan, and the air outlet side of the fan 4 is an axial end of the fan 4. The dust collecting electrode 3 can be arranged at one end of the fan 4 in the axial direction of the air outlet, and the corona electrode 2 can be arranged at the other end of the fan 4 in the axial direction or at one side of the fan 4 in the radial direction.

The utility model provides an among the blowing assembly, corona electrode 2 and fan 4's positional relationship can also set up to multiple, only need ensure that the wind pressure that fan 4 formed can drive corona electrode 2 air flow on every side can.

It is worth to be noted that the air duct is provided with an air inlet and an air outlet, and when the fan 4 and the electrostatic precipitator 1 work together to remove dust, the air outlet of the air duct should be closed to prevent the fan 4 from directly blowing the dust out of the air duct.

In addition, it can be understood that the corona electrode 2 ionizes air to generate partial positive ions, and a small amount of dust particles are directly adsorbed to the corona electrode 2 after being combined with the positive ions.

In addition, it should be noted that the utility model provides a blow subassembly is used for installing in air treatment equipment, and air treatment equipment can be air conditioner, air purification device etc.. The air treatment device also comprises other components which can be arranged inside the air duct of the blowing assembly. For example, in one embodiment, the air treatment device is an air conditioner, and the air conditioner further comprises a cross-flow fan, a heat exchanger and the like, which are arranged in the air duct of the blowing assembly. After the air conditioner works for a long time, the components are easy to carry static electricity, so that dust is adsorbed or the normal working state of the components is influenced. When the fan 4 is rotated to spread the negative charge generated by the corona electrode 2 evenly into the wind tunnel, the negative charge helps to neutralize the static electricity carried by these components.

The embodiment of the utility model provides a subassembly of blowing removes dust through electrostatic precipitator 1 and 4 cooperation works of fan, electrostatic precipitator 1's corona electrode 2 is used for the ionized air, collection dirt utmost point 3 is used for adsorbing the dust of negative electricity, fan 4 is located same wind channel with electrostatic precipitator 1 and just collects dirt utmost point 3 and sets up the air-out side at fan 4, thereby fan 4 can rotate so that the negative charge that corona electrode 2 produced and the dust homogeneous mixing in the wind channel, and make the electrified dust in the wind channel flow to collection dirt utmost point 3, in order to adsorb in collection dirt utmost point 3. Through the cooperation of electrostatic precipitator 1 and fan 4, can clear away the dust particle in the whole wind channel, improve dust collection efficiency.

On the basis of the above embodiments, optionally, in some embodiments of the present invention, the fan 4 has a high-speed operation mode and a low-speed operation mode. The fan 4 can diffuse the negative charges generated by the corona electrode 2 in the air duct in the high-speed operation mode, and the fan 4 can blow the negatively charged dust in the air duct toward the dust collecting electrode 3 in the low-speed operation mode.

It will be appreciated that the higher the speed of the fan 4, the faster the air flow in the air duct, the faster the negative charge generated by the corona electrode 2 will diffuse, and the more readily it will bind to and diffuse evenly throughout the air duct space with dust particles elsewhere in the air duct.

Meanwhile, the higher the rotation speed of the fan 4, the easier it is to blow off the dust adsorbed on the dust collecting electrode 3, resulting in a decrease in dust collecting effect.

Correspondingly, the fan 4 is difficult for blowing off the dust adsorbed on the dust collecting electrode 3 in the low-speed state, and is favorable for the dust with negative charges in the air duct to flow along with the air, finally flows to the air outlet side of the fan 4 and is adsorbed on the dust collecting electrode 3, so that the dust with negative charges in the whole air duct can be adsorbed by the dust collecting electrode 3, and the actual action range of the dust collecting electrode 3 is enlarged.

Meanwhile, the lower the rotation speed of the fan 4, the more inconvenient it is for the electric charges generated by the corona electrode 2 to be diffused in the wind tunnel.

Therefore, when the utility model provides a fan 4 and electrostatic precipitator 1 cooperation work of subassembly of blowing are in order to remove dust, can make fan 4 work at high-speed operation mode earlier to make more dust particles combine with the negative charge, the dust particle who carries the negative charge spreads in whole wind channel.

Moreover, in some embodiments, the blowing assembly is mounted on the air processing equipment, and other components of the air processing equipment are also mounted in the air duct of the blowing assembly, so that the fan 4 in the high-speed operation mode can easily blow off dust accumulated on other components.

After the fan 4 works for a period of time in the high-speed operation mode, the dust with negative charges is uniformly distributed in the air channel, so that the fan 4 can be switched to the low-speed operation mode, and the dust with negative charges is slowly adsorbed on the dust collecting electrode 3 along with the air flow and is not easy to blow away.

After the fan 4 is operated for a period of time in the low speed operation mode, the dust collecting electrode 3 can adsorb dust in substantially the entire air passage.

On the basis of the above embodiments, optionally, in some embodiments of the present invention, the corona electrode 2 is provided with a tip structure for tip discharge.

It can be understood that when the surface of the object carries charges, the surface charge density is high at places with large curvature of the surface of the object, such as edges, corners, tips of fine objects and the like, so that the electric field intensity near the tips is remarkably enhanced, the breakdown voltage of air is more easily reached, and the air is ionized. This phenomenon is known as "point discharge".

The corona electrode 2 is provided with a pointed structure, so that air is more conveniently ionized. For example, in one embodiment, as shown in fig. 1, the corona electrode 2 is configured as a rod, and a thin rod with a smaller diameter is disposed at one end of the rod-shaped corona electrode 2, and the thin rod can be used as a tip structure of the corona electrode 2, and a tip discharge phenomenon is more easily generated at the end of the thin rod.

In another embodiment, the corona electrode 2 may be configured in a needle shape, which is more likely to generate a point discharge phenomenon at the tip end of the needle.

In addition, the corona electrode 2 may further have a plurality of tip structures, such as a sawtooth structure, a polygonal star structure, etc. on the outer surface of the corona electrode 2, so as to enhance the tip discharge phenomenon.
