JPS6157253A - Ion wind type air purifier - Google Patents

Abstract

PURPOSE:To prevent the beat of an ionization wire due to the adhesion of dust, by providing the ionization wire to an ionization frame under tension through a spring and arranging a cylindrical pipe to the outer periphery of the spring in a coaxially circular form. CONSTITUTION:An ionization wire 1 is provided to an ionization frame 5 under tension through a spring 4 and a cylindrical pipe 7 is arranged to the outer periphery of the spring 4 in a coaxially circular form. The ionization wire begins to vibrate by attraction force and the spring 4 is also vibrated to be brought to a resonant sate but vibration is distincted by the pipe 7 outside the spring 4. The dimension of the pipe 7 is set so as to form some gap between the pipe and the spring. Because the vibration is eliminated by this method, a beat is prevented and trouble due to the adhesion of dust is hard to generate.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention moves an air-based insulating fluid using ion wind 7U, and in the flow process, impurity particles contained in the fluid, This invention relates to an ionic air purifier that removes pollutant particles, etc.

Conventional configuration and its problems First, the principle of generation of ion wind will be briefly explained.

Io7. R is an ion generated by corona discharge that moves along the lines of electric force, and in the process of this movement, it repels many neutral molecules, which is induced by the collision of molecules with M, that is, wind. It is.

By using this ionized wind, it is possible to circulate air without using a fan, and if this is applied to an air purifier, it can be used as an air purifier that has features such as noiseless, small size, and low cost. can do. The electrode configuration of this conventional ion wind air cleaner will be explained with reference to FIG. This consists of a discharge electrode 1 that generates a corona discharge, that is, a parallel plate-shaped counter dust collection electrode 2 installed at a constant interval from the ionization line, and a flat plate-shaped auxiliary plate that generates a high electric field between the counter dust collection electrode 2 and the discharge electrode 1 that generates a corona discharge. Electrode 3J: is configured as follows. DI and D2 represent high voltage power supplies, and E represents earth.

The principle of operation is that a high voltage is applied between the ionization wire 1 and the counter dust collection electrode 2 to generate a corona discharge, inducing an ion wind as shown by the arrow in the figure, and sucking and exhausting the processing air. At the same time, the dust in the processing air is charged and
Dust is collected on the electrode 2 due to the high electric field between the two.

The above is the operating principle of the ion wind air purifier. Conventionally, in this type of air purifier, the ionization wire, which is the ionization electrode, is made of aluminum or iron plate, as shown in Figures 2 and 3. A tension spring 4 is attached to the frame 6 made of stainless steel, etc., and an ionized Fa1 tightened by a tome 8 is attached to the spring 4 using a joint structure. However, as can be seen from the principle diagram shown in Fig. 4, by inducing an ion wind and sucking and exhausting the treated air, dust will be deposited on the electrode 2, but the ionization line 1 The strength of the electric field that generates corona discharge by applying a high voltage between the electrode 2 and the opposite electrode 2 changes as the dust 6 adheres to the lotus 2, and the electric field strength becomes even higher. , the ionization wire 1 begins to vibrate due to the attraction force. The vibration causes burrs f) in the ionized wire 1, which causes noise and requires electrode cleaning. Therefore, it is necessary to increase the number of times of cleaning with less dust attached.

Figure 6 is the ionized charge shown in Figure 2! , which shows an enlarged view of part A. In Figure 5, a weight 6 is attached to the spring 4 as a method of preventing vibration, but the effect varies depending on the amount of dust attached. will occur.

Purpose of the Invention The present invention is intended to solve such problems, and aims to improve quality and performance by preventing the ionization line from generating beats even when a large amount of dust is attached.

Structure of the Invention In order to achieve this purpose, F! A is a type in which an ionizing wire is stretched around an ionizing frame via a spring, and a cylindrical pipe having the same volume is arranged around the outer periphery of the spring.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 6 shows a second embodiment of the present invention, similar to FIG. 3.
This is an enlarged view of part A of the ionization electrode shown in the figure, where 5 is a frame, 1 is an ionization line, 4 is a spring, and 8 is an eyelet. Further, 7 is a cylindrical pipe of the present invention, which is disposed around the outer periphery of the spring 4 in the same circular shape. By arranging the pipe 7'4 around the outer circumference of the spring 4, the ionization source 1 vibrates,
Even if the spring 4 also vibrates and resonates, the vibration disappears because the pipe 7 is disposed outside the spring 4.

Friend, if the dimensions of the pipe 7 are that the outer dimensions of the spring 4 and the inner dimensions of the pipe 7 are almost equal, then if the pipe 7 is placed in close contact with the spring 4 and the spring 4 vibrates, the pipe 7 This makes it difficult to absorb vibrations. Therefore, it is necessary to provide a certain amount of space between the spring 4 and the paigua. As for the shape, if it is cylindrical as shown in Figure 7a%d, the same effect can be obtained.Effects of the InventionAs described above, according to the present invention, the ion It is possible to prevent the ionization wire from buzzing due to dust adhering to the wind-type air purifier, and it is also less likely to cause problems even if a large amount of dust adheres to the electric abrasive plate, resulting in maintenance improvements such as a reduction in the number of times of cleaning. But it will be practical.
