Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water circulation sterilization type shower device which is also equipped with sterilization means and which filters water once used for showering and uses it again.

Conventionally, in conventional shower devices, water such as tap water or the like is guided to the shower outlet either as is or after being heated, and the water after washing the human body or the like is discarded as is. For this reason, when introducing a shower device into a home, piping to lead tap water and piping to drain sewage is required, and the equipment construction costs are quite large. It's not easy.

The invention solves the problem.The present invention (well, by purifying the wastewater from the shower equipment and using it again as raw water for the shower, there is no need for water supply piping and drainage piping, and the introduction of shower equipment into homes is possible. The purpose is to easily disinfect the water and also to improve the hygiene level by sterilizing reused water.

Means for Solving the Problems The water circulation type shower device of the present invention that meets this objective includes a shower room, a water recovery tank provided below the shower room, a water purification tank provided above the shower room,
A water passage that connects the water recovery tank and the water purification tank, and a pump that circulates water from the water recovery tank to the water purification tank;
It consists of a filtration means installed upstream of the water purification tank, and a sterilization means installed at or upstream of the water purification tank.

Function: In the device configured as described above, the waste water after washing the human body etc. in the shower room is collected in the water recovery tank.
The water is pumped through the water passage towards the clean water tank. The waste water is purified by a filtration means before entering the water purification tank, and is sterilized in the water purification tank or upstream thereof, and the sewage that enters the water purification tank is purified to the same degree as new water.

The purified water in the purified water tank is discharged from the shower room water outlet in the shower room. The water is recycled by repeating this process. For this reason, there is no need for any piping to lead or drain tap water, and the shower device can be made into a unit. Moreover, the water is sterilized, which is good for hygiene.

Embodiments Below, preferred embodiments of the water circulation sterilizing shower apparatus of the present invention will be described with reference to the drawings.

FIG. 1 shows an example device in a transparent state, and FIG. 2 shows a cross section of the device. In the figure, 1 is a shower room, which is surrounded by a box 2. The box 2 may have a collapsible structure. Although the shape of the box 2 is a rectangular parallelepiped in the illustrated example, it is not necessarily limited to the rectangular parallelepiped. The box 2 has a door 2b through which people enter and exit the shower room 1.

A water recovery tank 3 is provided below the shower room 1. The water recovery tank 3 is a cartridge type, and the tank can be pulled out.゛The lower wall 2a of the box above the water recovery tank 3 has a water-permeable structure, and the water used in the shower flows from the shower room 1 to the water recovery tank 3.
It has a structure that allows it to fall under its own weight and be collected. The lower wall 3a of the water recovery tank 3 is inclined toward one end, so that the wastewater in the water recovery tank 3 is efficiently collected in one place. The water recovery tank 3 includes a filtering means 3 made of, for example, an activated carbon layer, for removing bulky waste from the sewage.
b is provided. A pipe 4 serving as a water passage is exposed corresponding to the lowered portion of the bottom wall 3a, and the pipe 4 penetrates the shower room 1 and rises up.

A pump 5 is provided at a suitable location on the pipe 4, at the upper end in the illustrated example, and the pump 5 pumps the dirty water in the water recovery tank 3 upward. A discharge port of the pump 5 faces the filtering means 6. The filtration means 6 is one that can quickly remove and purify dirt and grime in waste water, and has a filtration layer 6a made of activated carbon, for example. The activated carbon layer 6a may also consist of a combination of reticulation and chemical cleaning agents. Also,
The water that has passed through the filtration means 6 is led to the sterilization means 10.

The sterilizer 10 has a sterilizer tank 10c which has a weir 10a and is separated from a water purification tank 7, which will be described later, and is provided with an ultraviolet lamp 10b for sterilization corresponding to the sterilizer tank 10c. The sterilization means 10 may be provided in the water purification tank 7.

Moreover, the sterilizing means may supply an appropriate amount of a sterilizing agent such as chlorine instead of using the ultraviolet lamp 10b. The filtration means 6 is of a cartridge type, and the filtration layer 6a can be replaced.

A water purification tank 7 is provided downstream of the filtration means 6, and the purified water that has passed through the filtration means 6 is stored therein. The water purification tank 7 is of a cartridge type and can be pulled out. The water purification tank 7 may be formed separately from the transit means 6 or may be formed integrally therewith.

A hose 8 is connected to the water purification tank 7 so as to be able to move freely, and the hose 8 extends into the shower room 1 and is connected to a shower water outlet 9. The shower water outlet 9 may be one that can be freely handled by a person as shown in the illustrated example, or may be a fixed type. Although not shown in the drawings, the shower room is equipped with electric lights and has a waterproof structure.

Next, the operation of the above embodiment device will be explained.

First, after the shower water discharged from the shower water outlet 9 in the shower room 1 washes the human body, it falls to the lower wall 2a of the box 2 under its own weight, passes through the water passage structure of the lower wall 2a, and then The water is collected in the water recovery tank 3 below. The dirty water that has entered the water recovery tank 3 has bulky waste removed by its filtering means 3b, and then flows to the lowered portion of the lower wall 3a of the water recovery tank 3. The water in the water recovery tank 7 passes through the pipe 4 and is pumped upward by the pump 5. The water pumped up by the pump 5 is passed through the filtration means 6, and when the filtration means consists of an activated carbon layer, the activated carbon layer 6a
passed through, filtered and purified. Next, the filtered water is sterilized by irradiation with ultraviolet light from the lamp 1'Ob of the sterilization means 10. The sterilizing means is a sterilizing agent supplying means of a sterilizing agent such as chlorine (
(not shown), the purified water is sterilized by chlorine.

This sterilization further improves hygiene. Purified water has the same purity level as fresh water.

The purified water flows to the purified water tank 7 and is stored there. When a person uses a shower, water stored in a water purification tank 7 flows through a hose 8 to a shower water outlet 9, is scattered from the shower water outlet 9, and is used for bathing the human body. The water falls again under its own weight to the lower wall 2a of the box 2 and circulates.

From then on, this cycle repeats.

While the water is being recycled in this way, the freshness of the water decreases, and in that case, the cartridge-type water recovery tank 3 and water purification tank 7 are pulled out and the water is replaced, and the water is filtered. When a large amount of dirt has adhered to the filtration layer 6a of the means 6 and the filtration layer 3h of the water recovery tank 3 and the purification ability has decreased, the filtration means 6, which is a car i-ridge type,
Pull out the water recovery tank 3 and replace the Lanka layer 6''s3b with a new one.

Effects of the Invention As is clear from the above explanation, when using the water circulation sterilization type shower device of the present invention (unlike conventional shower devices, water can be easily sterilized by circulating water), pipes and drainage from tap water can be easily sterilized. Since no piping is required, it is possible to easily introduce a shower system into a garden or garden, which reduces equipment construction costs, and has the effect of improving hygiene through sterilization.
