Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air cleaner using an electrostatic precipitator method and equipped with an ionization section, which is used indoors, in automobiles, or in clean rooms.

The configuration of the conventional example and its problems Figure 1 shows the (74 configuration) of the conventional example. 101 is the intake port 10.
2. A main case having an exhaust port 103 and a lid 104 rotatably attached to the front side, and 105 is an ionization electrode made of a tungsten wire or the like. 106 and 10
7 is a dust collecting electrode and an accelerating electrode, each of which is connected to a fastening rod 101.
3 and 109 and are integrally connected, and a distance is provided between the dust collecting electrode 106 and the accelerating electrode 107 to ensure electrical insulation, and the electrodes are integrally connected with an insulating material 110 such as porcelain interposed therebetween. It is installed on the rib 111 of the biological case 10i. A high electric field is formed between the ionization electrode io5 and the dust collection electrode 106 and between the dust collection electrode 106 and the acceleration electrode 107 due to the high voltage applied by the high voltage power supply 112. In the above configuration, the ionization electrode 1
The corona discharge generated at 05 ionizes air molecules and generates ions. When these ions move toward the dust collection electrode 106 along the lines of electric force, they collide with a large number of neutral molecules, causing them to move and create wind. At the same time, the charged dust is charged at the dust collection electrode 106. Electrostatic force is received between the accelerating electrode 106 and the accelerating electrode 107, and the dust is collected on the dust collecting electrode 106 side. At this time, it is sometimes necessary to remove collected dust from the electrostatic precipitator, which is composed of the precipitate electrode 106 and the accelerating electrode 107, by cleaning, etc., but conventionally, the precipitator is heavy and difficult to operate. A mechanism for attaching and detaching the power receiving part (not shown) of the dust collection electrode 106 and the accelerating electrode 107 is required, which results in a complicated structure and high cost, especially in the high voltage power receiving part, and the problem that the high voltage applying side electrode (in this example) There were problems such as a residual charge being generated in the accelerating electrode 1o7), which may cause a shock due to static electricity during operation.

Purpose of the Invention The present invention solves the above-mentioned conventional problems and provides an air cleaner equipped with an electrostatic precipitator that is easy to perform maintenance operations such as cleaning, has a simple configuration of the power receiving section, and is free from shocks caused by static electricity and is highly safe. The aim is to provide the opportunity.

Structure of the Invention The present invention comprises an air blowing means provided in a main case, an ionization section, and an electrostatic precipitator composed of a precipitate collecting electrode and an accelerating electrode that form a high electric field between them. The accelerating electrodes of the dust part are integrally connected at the front side in the ventilation direction and fixed to the main case, and the dust collection electrodes are integrally connected at the rear side in the ventilation direction, and the position where the connecting member of the mating electrode of each electrode passes through. The accelerating electrode has a notch with an opening on the rear side in the ventilation direction, and the dust collecting electrode has a notch with an opening on the front side in the ventilation direction, and the lid attached to the main case, which has an exhaust port, can be opened on the rear side in the ventilation direction. It is designed so that only the dust collecting electrode can be taken out in an integrated state.

DESCRIPTION OF EMBODIMENTS Next, one embodiment of the present invention will be described based on FIGS. 2 and 3. Reference numeral 1 denotes a main case which is provided with an intake port 2 for dust-containing air, an exhaust port 3 for clean air, and is attached with a lid 5 which is rotatable about a fulcrum 4 and is normally fixed with screws. 6 is an ionization electrode made of tungsten wire, etc., which is held in the biological case via a power receiving part (not shown); and 8 are dust collection electrodes and acceleration electrodes (fastened).
9. They are each separately and integrally connected by a connecting member consisting of 10. That is, the acceleration electrode 8 is connected at the front side in the ventilation direction (indicated by an arrow in the figure) with a fastening rod 1Q, and is formed inside the main case 1. It is fixed to the holding part 11 via a power receiving part (not shown), and the dust collecting electrode γ is integrated with a fastening rod 9 on the rear side in the ventilation direction and is detachably held in the biological case 1.

Then, at the position where the coupling rod of the mating electrode of each electrode passes, the accelerating electrode 8 is placed on the rear side in the ventilation direction, and the dust collecting electrode 7'I'
i A notch 12 having an opening on the front side in the ventilation direction is provided.

A high voltage is applied between the ionization electrode 6 and the dust collection electrode 7 and between the dust collection electrode 7 and the acceleration electrode 8 by a high voltage power supply 13 to form a high electric field.

In the above configuration, the air blowing and dust collecting action is performed based on the same operating principle as the conventional example. At this time, the charged dust is attracted only to the dust collecting electrode 7 due to electrostatic force, and the dust does not adhere to the accelerating electrode 8. When maintenance such as cleaning is required, only the integrated dust collecting electrode 7 can be removed from the opening of the lid S, reducing the weight of the operating section (compared to the conventional V2) and improving operability. improves. Further, since the accelerating electrode 8 can remain fixed to the main case 1, the power receiving section does not require an attachment/detachment mechanism, which simplifies the configuration. Furthermore, since the dust collecting electrode 7 is at ground potential, no residual charge is generated and there is no need to worry about being shocked by static electricity during operation.

In this embodiment, the case where an ion wind is used as the wind source has been described, but it is clear that the same applies to other wind sources such as fan motors.

Effects of the Invention As described above, according to the present invention, the ease of handling and safety during maintenance of the electrostatic precipitator are significantly improved, and the configuration is simplified, making it possible to reduce the cost of the equipment. It is a dog of industrial value.
