Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in an ozone concentration control structure in a cleaning device.

[Conventional technology]

In recent years, organic substances such as liquid crystal glass, metals, and plastics adhering to the surface of various works have been washed to ensure the adhesion and sealing of other surfaces.

In order to clean the organic substances on the surface of the work, conventionally, in general,
A reflector is provided inside the box-shaped device main body, and an ultraviolet lamp for ozone cleaning is arranged inside the reflector, and a work such as liquid crystal glass, metal, or plastic is placed on the lower surface of the ultraviolet lamp for ozone cleaning. The organic substances on the surface of the work are cleaned by arranging them and using ozone and ultraviolet rays generated from the lamp.

[Problems to be solved by the device]

However, if the organic substances on the surface of the work such as liquid crystal glass, metal, and plastic are washed with ozone and ultraviolet rays in the above-mentioned washing device, the concentration of ozone rises, but oxygen is insufficient and active oxygen is less generated, and the washing effect decreases. In addition, since the ozone concentration is high, the ultraviolet rays do not reach the work in the required amount, and the cleaning of organic substances by the ultraviolet rays becomes insufficient.

[Purpose of device]

The present invention has been devised in view of the above points, and an object of the present invention is to provide an ozone concentration control structure in a cleaning device capable of controlling ozone concentration and effectively decomposing organic substances by ozone and ultraviolet rays. .

[Means for Solving the Problems]

The present invention has the following configuration to solve the above problems.
That is, a reflector is provided inside the box-shaped device body, and multiple ozone cleaning ultraviolet lamps are installed inside the reflector so that the ozone cleaning ultraviolet lamps can be turned on continuously. Constitute.

Further, a tray on which a work is placed can be freely taken in and out on the lower surface of the ozone cleaning ultraviolet lamp, and a large number of pores are formed at the bottom of the tray.

In addition, a blower is installed to take in fresh air from the outside of the equipment into the inside of the equipment, and the fresh air from the outside of the equipment is brought closer to the ultraviolet lamp for ozone cleaning by the blower. It is configured such that it is discharged to the outside through the gas and the ozone concentration is controlled.

[Action]

According to the ozone concentration control device in the cleaning device described above, after fresh air outside the device enters the inside of the device, it passes through the ozone cleaning ultraviolet lamp in close proximity, and after that, a large number of pores are formed at the bottom of the tray. Since the ozone concentration is controlled, the ozone and the ultraviolet rays do not interfere with the transmission of the ultraviolet rays, and the ozone and the ultraviolet rays reach a predetermined amount on the surface of the work, and the organic matter is decomposed well.

[Embodiment] The present invention will be described below with reference to FIG. In the figure, 1
Is a box-shaped apparatus main body, 2 is an ultraviolet lamp for ozone cleaning which is mounted inside the apparatus main body 1 so as to be continuously lit, and includes, for example, a plurality of 25 watt straight-tube low-pressure discharge lamps. It is composed of lights. Reference numeral 3 denotes a reflector provided inside the apparatus main body 1 and located above the ozone cleaning ultraviolet lamp 2, and a plurality of reflectors are arranged at equal intervals at positions corresponding to the central axis in the longitudinal direction of the ozone cleaning ultraviolet lamp. The air holes 4 are provided.

Reference numeral 5 denotes a tray which is located on the lower surface of the ozone cleaning ultraviolet lamp and which is configured to be freely taken in and out. Reference numeral 7 denotes a blower for introducing fresh air from the outside of the apparatus into the inside of the apparatus, and is configured to guide the fresh air from the outside of the apparatus main body 1 into the inside of the apparatus main body 1. Further, the air guided into the apparatus main body 1 by the blower 7 passes through the ozone cleaning ultraviolet lamp 2 in close proximity, and further passes through the large number of pores 6 at the bottom of the tray 5 to be discharged to the outside. . Reference numeral 8 denotes a filter provided at an air hole of the apparatus main body 1, which is, for example, an air-permeable molded activated carbon and is configured so that dirty air outside does not enter the inside of the apparatus main body.

[Effect of device]

As described above, according to the present invention, fresh air outside the main body of the apparatus is introduced into the main body of the apparatus by the blower, and then passes close to the ultraviolet lamp for ozone cleaning. Since it is discharged to the outside through the holes, the ozone concentration is controlled, ozone does not hinder the transmission of ultraviolet rays, and there is an advantage that organic substances can be effectively decomposed by ozone and ultraviolet rays.
