Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a built-in dust collecting unit used for air conditioners, oil fan heaters and the like.

[0002]

2. Description of the Related Art Conventionally, a built-in dust collecting unit used for an air conditioner, an oil fan heater, etc., has dust particles due to corona discharge in an ionizer section 3 composed of an ionizing electrode 1 and an ionizing electrode plate 2 as shown in FIG. Charge 4
FIG. 3 shows a two-stage type electrostatic precipitating system having a dust collecting electrode 8 composed of a positive electrode plate 6 and a negative electrode plate 7 for collecting the charged dust particles 5 by Coulomb force. As shown in the drawing, the electrostatic filter 9 is pleated, and the electrostatic filter 9 is of a charging type that prolongs the life of the electrostatic filter 9 by charging the positive charging electrode net 10 and the negative charging electrode net 11 from both sides. And have been used.

[0003]

However, in the above-mentioned conventional configuration, the electrostatic filter charging type is a dust type due to the collision of the dust particles 4 due to the flow of wind on the charged fibers constituting the electrostatic filter 9. Since the particles 4 adhere to each other, a high pressure loss occurs, and since the charging work for relaxing the electrical neutralization of the charged fibers due to the adhesion of the charged particles in the natural environment is not in contact with the charged fibers, the voltage used is safer. However, there is a problem that a sufficient life cannot be obtained, thinning and cost reduction are possible, but high performance and low pressure loss cannot be achieved at the same time. Further, the two-stage type electrostatic precipitator uses the Coulomb force to collect the charged dust particles 5 charged in the ionizer unit 3, which enables higher performance and lower pressure loss, but the ionizer unit 3 and the dust collecting electrode Since 8 and 8 are separately arranged on the front and rear sides, there is a problem that thinning and cost reduction cannot be satisfied.

The present invention is intended to solve the above problems,
It is an object of the present invention to provide a dust collecting unit that can satisfy the requirements of built-in high performance, low pressure loss, thin shape, and low cost.

[0005]

In order to achieve the above-mentioned object, the present invention provides an air-impermeable ionizer section comprising an ionization electrode and an ionization electrode plate, and a collection of charged particles charged by the ionizer section. The dust collecting electrode is disposed on substantially the same plane and integrated.

[0006]

Therefore, according to the present invention, the high performance and the low pressure loss are satisfied because it is the electric dust collecting method, and the ionizer section and the dust collecting electrode are arranged on the same plane and integrated, so that it is made thin. And it becomes possible to achieve cost reduction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 and FIG.

FIG. 1 is a block diagram of a dust collecting unit according to an embodiment of the present invention. As shown in the figure, arrows indicate the flow of wind, and ionization of a tungsten wire having a diameter of 100 μm to which a positive high voltage is applied. An ionizer part 3 composed of an electrode 1 and an ionization electrode plate 2 to which a negative voltage is applied, which does not allow bottomed air to pass through, and a positive electrode plate 6 and a negative electrode plate 7 on substantially the same plane as the ionizer part 3. The dust collecting electrodes 8 consisting of are arranged on the left and right of the ionizer portion 3.

Next, the operation will be described. The dust particles 4 carried by the wind are charged by corona discharge in the ionizer section 3 to become charged dust particles 5.
Since it has a bottom, the charged dust particles 5 do not pass through and overflow from the ionizer part 3, pass between the dust collecting electrodes 8 arranged on the left and right of the ionizer part 3 on the same plane, and the coulomb of the dust collecting electrode 8 It adheres to the negative electrode plate 7 by force.

As described above, the dust collecting unit of this embodiment is
Satisfies high-performance dust collection and low pressure loss equivalent to those of the two-stage electrostatic dust collection system, and because they are arranged and integrated on the same plane, it is possible to achieve thinning and cost reduction. It was

In this embodiment, the line electrode is used as the ionization electrode 1, but the same effect can be obtained by using the needle electrode.

[0012]

As is apparent from the above-described embodiment, the present invention is an ionizer portion composed of an ionization electrode and an ionization electrode plate that does not let air pass through, and a dust collecting electrode for collecting charged particles ionized by the ionizer portion. Since and are arranged and integrated on substantially the same plane, extremely excellent high performance and characteristics such as low pressure loss can be obtained, and thinning and cost reduction can be achieved.
