Description

[Detailed Description of the Invention] This invention relates to an ozone sterilization device in a device connected to a bathtub for circulating and purifying bath water.

(Prior Art) A bath water purification device is used which is equipped with a circulation pump, a filter, an active purification tower, an auxiliary heater, and an ozone blowing means.

Although ozone is effective in sterilizing bath water, ozone itself is harmful to the human body.

However, in the past, ozone was blown out or simply injected into the bathtub or in the pipe just before the bathtub, so some of the ozone did not contribute to sterilization and was diffused in the bathroom, which was harmful to the human body. It was necessary to perform the blowing intermittently.

Furthermore, the disadvantage of injecting ozone into the pipeline is that it generates unpleasant vibration sounds as the ozone bubbles expand or disappear.
In addition to impairing the pleasure of bathing, the water that is returned to the bath water contains unnecessary air bubbles.

(Objective) The object of the present invention is to provide an ozone sterilizer that eliminates the above-mentioned essential drawbacks, does not generate vibration noise, and can supply ozone-sterilized purified water to a bathtub in the form of degassing and rectification without pulsating flow.

(Structure) The present invention consists of installing a partition plate vertically inside the cylindrical sterilization tank except for the upper part, and dividing the inside of the tank into an ozone agitation chamber and a deaerated water chamber.
At the same time, a porous cylinder for bubble growth is vertically installed and fixed in the agitation chamber, and an ejector device for injecting circulating water and ozone is installed on the upper lid of the sterilization tank, and is located inside the perforated cylinder. An automatic air bleed valve is provided outside the porous cylinder, and a discharge pipe is connected to the bottom of the deaerated water chamber.

(Example) In Fig. 1, 1 is a circulation purification device, 2 is a suction pipe, 3 is a self-priming pump, and 4 is a filtration purification tower, which has a cylindrical bellows filter 5 on the inside and two upper and lower stages on the outside. It is constructed by accommodating purification activated stone storage bodies 6 and 7.

8 is piping, 9 is an ejector device, 10 is a controller box containing an ozone generator, 11
12 is an ozone injection pipe, 12 is an ozone sterilization tank, 13 is a known automatic air release valve, 14 is a gas diffusion pipe, 15 is a discharge pipe, and 16 is an auxiliary heater equipped with water and temperature sensors and connected to the supply pipe 17. are doing.

The structure of the ozone sterilization tank 12 is as shown in FIGS. 2 and 3, in which the inside of the bottomed cylinder 20 is divided by a partition plate 21 excluding the upper communication part 22, and the ozone mixing and agitation chamber 23 is separated from the ozone mixing and agitation chamber 23. An air/water chamber 24 is formed.

Reference numerals 25 and 26 are cylindrical bodies made of wire mesh or punched metal, which serve to guide the jet stream from the ejector downward, promote contact between gas and liquid, and promote the growth of air bubbles.

This cylindrical body may be arranged concentrically with respect to the ejector 9, or may be eccentrically arranged as shown in FIG. Also, the mounting method is arbitrary.
7 can also hold the clamping pressure.

(Function) In the above device, the ozone mixed water flow from the ejector 9 is guided downward along the inside of the wire mesh cylinder 25, while stirring the surrounding water and enhancing the sterilizing effect of the ozone contained therein. Once dissolved, the ozone decomposes into oxygen and comes into contact with the wire mesh to promote the formation of bubbles together with the air contained therein, grow large, and are released onto the liquid surface and accumulated in the air pocket 28 at the top of the tank.

Automatic air release valve 1 depending on the water level or pressure in the tank
3 is activated and excess gas is discharged from the discharge pipe 14 to the outside.

The water deaerated in the upper part of the agitation chamber 23 flows over the upper edge of the partition plate 21 into the deaerated water chamber 24,
While it remains here, it is further degassed.

The water discharged into the discharge pipe 15 is rectified and introduced into the bathtub without containing ozone or air bubbles.

(Effects) In this device, the jet water flow from the ejector is injected into the water inside the agitation chamber, so there is no vibration noise, and since the inside of the tank is sealed, no sound leaks outside, making it quiet. .

The bath supplied through the proposed device has been sterilized with sufficient ozone contact time, so a small amount of ozone is sufficient. Furthermore, due to deaeration, the amount of dissolved gas components is small, so gas can be kept in the circulation suction pump. Since this does not occur, there is no water hammer phenomenon, which has the effect of increasing the life of the pump.
