Abstract

PROBLEM TO BE SOLVED: To surely and simply prevent discharge efficiency from being lowered due to adhesion of oil to a discharge part by providing an oil-mist adsorption filter upstream of an electrode in an apparatus for removing smoke and offensive odors in air by generating corona discharge between a discharge electrode and an opposite electrode. SOLUTION: In a case, e.g. the case that meat is broiled by using a hot plate 21 placed on a table, a cleaning device main body 1 is placed in such a manner as to locate a cleaner main body 7 above the hot plate 21. Oil mist 22 produced by broiling the meat is sucked through a suction hole 10 of the cleaner main body 7 into a guide 12 by action of a blower 9 and oil contents and the like in the oil mist 22 are adsorbed and removed by an oil mist adsorption filter 14. The oil mist is made free from smoke and deodorized by a dust- collecting electrode 13 to be cleaned and then discharged into a room through a discharge hole 19. Part of supplied air is jetted from an air supply hole 20 through an air supply passage 21 whirlingly so as to catch and draw the oil mist and the like and suck them through an air suction hole 10 so that cleaning efficiency is enhanced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flue gas purifying apparatus for removing oily smoke and odor generated by grilled meat, smoke of cigarettes and offensive odor.

[0002]

2. Description of the Related Art An air purifier has been proposed, for example, in Japanese Utility Model Laid-Open Publication No. Sho 62-136233, in which a direct current voltage is applied between a discharge electrode and a counter electrode to generate corona discharge to remove smoke and odor from cigarettes. However, if, for example, grilling meat is performed around the air purifier and oil smoke is generated, there is a problem that oil contained in the oil smoke adheres to the counter electrode and the discharge efficiency is reduced.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to remove smoke and odor in the air by corona discharge, and to prevent a decrease in discharge efficiency due to adhesion of oil to a discharge portion. It is.

[0004]

According to the present invention, an oil mist adsorption filter is disposed upstream of an electrode in which a corona discharge is generated between a discharge electrode and a counter electrode to remove smoke and odor in the air. It was done.

Further, the present invention provides a blower for sucking indoor air to the electrodes and the oil mist suction filter and blowing the air therein, and a blower port for blowing air in a spiral shape upstream of the oil mist suction filter. is there.

The present invention further provides an electrode and an oil mist adsorption filter in a suction passage of the blower, and blows a part of the blown air from the blower in a spiral form through a blower opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention will be described with reference to FIG.
A support 3 is erected on a stand 2, and a support arm 4 is pivotally supported on a top end of the support by a hinge 5 so as to be vertically rotatable, and a purifier body 7 is rotatable by a hinge 6 at the tip of the support arm. I support it.

The purifier body 7 has a hollow trapezoidal outer case 8 whose upper surface is closed, a blower 9 mounted on the upper part of the outer case, and a substantially central part in the outer case 8. A hollow cylindrical guide 12 having an intake hole 10 on the lower surface and a discharge hole 11 on the upper surface, a dust collecting electrode 13 mounted in the center of the guide, and a detachable mounting on the intake hole 10 of the guide 12 Oil mist adsorption filter 14
It mainly comprises a deodorizing filter 15 mounted on the discharge hole 11.

The oil mist adsorption filter 14
Is made of, for example, a non-woven fabric of polyester, and can be improved in lipophilicity by applying a mineral oil.

Further, the oil mist adsorption filter 1
If an electrostatic filter (not shown) made of a non-woven fabric of polypropylene or the like is attached to the intake side of 4, the oil mist adsorption capability of the oil mist adsorption filter 14 can be further improved. A plurality of needle-like discharge electrodes 16 are combined with a grid-like counter electrode 17 which is positioned so as to surround these discharge electrodes, and is housed in the stand 2 between these electrodes. A predetermined DC voltage is applied from the high voltage generation unit 18 to generate corona discharge.

On the other hand, a discharge hole 19 is formed in substantially the entire periphery of the outer case 8 at a position facing the blow-out portion of the blower 9 of the outer case 8, and between the outer case 8 and the guide 12. Defines an air passage 21 for guiding a part of the air blown by the blower 9 to a plurality of air outlets 20...

The air outlets 20 are opened at a predetermined angle so as to be swirled around the intake hole 10 as shown in FIG.
This is to purify the surrounding air more efficiently by sucking it through the intake hole.

For example, as shown in FIG. 1, when a hot plate 21 is placed on a table and grilled meat or the like is to be performed on the hot plate, the purifying apparatus main body 1 and the purifier main body 7 are connected to each other. By arranging it so as to be located above the hot plate 21, the purifier body 7 is
Oil smoke 22 generated by grilled meat is sucked into the guide 12 from the intake hole 10 of the above, and firstly, oil is mainly absorbed and removed from the oil smoke 22 by the oil mist adsorption filter 14, and then the smoke is smokeless by the dust collecting electrode 13. After being purified or deodorized, it is discharged into the room through the discharge holes 19.

Further, a part of the air blown by the blower 9 is
1, spirally blows out from the blowing ports 20..., And the oil smoke generated by the grilled meat and the air around it are swirled and sucked through the intake hole 10 to purify the oil more efficiently.

[0015]

According to the structure of the present invention, the oil mist adsorption filter is arranged upstream of the dust collecting electrode portion, thereby preventing oil from adhering to the electrode portion. It is possible to prevent a reduction in purification efficiency due to a mistake.

Further, according to the structure of the present invention, by providing a blower port for blowing air in a spiral form upstream of the oil mist adsorption filter, a blown flow is generated by the blown air blown from the blower port, and the swirl flow causes In addition, it is possible to more efficiently suck and purify distant air, thereby improving the purification efficiency without fail.

Further, according to the structure of the present invention, a part of the air blown by the blower for sucking air into the dust collecting electrode portion and the oil mist adsorption filter is spirally ejected upstream of the oil mist adsorption filter, whereby It is not necessary to provide a dedicated blower for generating a swirl flow, and it is possible to reduce the cost by reducing the number of parts and reduce the size of the device.
