Abstract

PROBLEM TO BE SOLVED: To save water and heat energy by recycling bath water by circulating and filtering bathtub water efficiently with minimum energy by floating a filter device in which a filter and a purifying material are housed on a water surface by a buoy and introducing the bath water sucked from the suction port of a pump into the filter device. SOLUTION: A porous ceramic purifying material 3 is housed in the container of a filter device 1, after a filter 2 being laminated on the purifying material 3, this is charged into a bathtub and floated by a buoy 4. Bath water 12 sucked from the suction port of a pump 10 is passed through pipes 7-5 in turn and introduced into a filter device 1, scale, hair, refuse, and the like, in the bath water 12 are removed by the filter 2, and dirt such as sweat in the bath water 12 is decomposed/removed by microorganisms in the purifying material 3. After that, the filtered bath water 12 is introduced into a bathtub 13 from a discharge hole in the bottom surface of the filter device 1 and circulated/purified constantly. The whole filter device 1 can be set in the bathtub 13 easily by holding the lid handle of the device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for circulating and filtering water in a bathtub for circulating and filtering water, thereby saving water and saving heat energy.

[0002]

2. Description of the Related Art A conventional circulating filtration apparatus is large in size and has a built-in heater for maintaining a constant temperature. Therefore, there is an advantage, but it results in loss of heat energy and is expensive.

[0003]

SUMMARY OF THE INVENTION The present invention recycles water in a bathtub with a minimum amount of energy to reuse the water and reduce the consumption of heat energy that is re-boiled to a suitable temperature, thereby saving water and saving energy. It is an object of the present invention to provide a simple, inexpensive, simple and inexpensive and easy to provide.

[0004]

Means for Solving the Problems The filter 1 containing the filter 2 and the purifying material 3 is always positioned on the water surface by the floating ring 4, so that the filter 1 is automatically kept on the water surface even when the water level changes. Attach the pipes 6 and 7 of large or small diameter or the bellows pipe 14 which can freely expand and contract to the discharge port of the pump 10 so that
The pump 10 sinks to the bottom of the bathtub 13 by its own weight, and the bath water 12 sucked from the suction port of the pump 10 is sent to the upper part of the filter 1 to be filtered using the flow of water.
Has a structure in which the bath water 12 in the bath tub 13 is easily circulated efficiently with minimum energy by flowing over the water surface of the bath water 12 through a hole formed in the bottom of the filter 1.

[0005]

According to the present invention, the above means have been taken. When using the filter, remove the lid on the upper part of the filter 1 and put the porous ceramics for the purifying material, put the filter on it, close the lid, close the lid and put the device in the bathtub. When the pump motor is turned on, the bottom water in the bathtub is sucked up by the pump and dirt such as scale, hair and trash is filtered by the filter in the filter. Due to dirt such as sweat,
It is decomposed and removed, and the water in the bathtub is constantly purified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present apparatus will be described below with reference to the drawings. In this embodiment, FIG. 1 shows that the container of the filter 1 is made of a synthetic resin, and the lid can be removed. This container is made of a transparent material so that the inside of the container can be seen, and has a number of holes formed on its bottom surface to allow water to flow out. Float 4
Requires a buoyancy to float the filter, and is made of a plastic floating ring that seals air and is removable. Pipes 5, 6, 7 of the water passage between the filter 1 and the pump 10 are
Using a synthetic resin pipe, put the pipe 7 inside the pipe 6 so that it can expand and contract lightly due to changes in water level,
Moreover, the resistance of the waterway was made as small as possible. A bellows type pipe 14 can be used instead of the pipes 6 and 7. The pipe 5 penetrates the center of the bottom of the filter 1, and the filter 1 and the pipe 5 are fixed with a screw ring 8 at a position where water can be sufficiently discharged from the tip of the pipe 5. Filter 1
Is fixed by a pipe 6 at a position (in this case, the height of a screw ring) where the discharge hole on the bottom surface of the filter 1 is not blocked through a hole in the center of the floating ring 4. The pipe 7 is attached to the discharge port of the pump 10 so that the pipe 7 can be inserted into the pipe 6 so that the pipe 7 does not come off longer than the required maximum length (the highest water level above the bottom of the bathtub). As shown in (1), a ring is fitted to the end of the pipe 7 and the lower end of the pipe 6 is tightened with a stopper screw 9. Also, since it is necessary to fix the length of the pipe depending on the mounting method, a rubber ring is inserted between the pipe 6 and the stopper screw 9 and the stopper screw 9
By strongly tightening, the pipe 6 and the pipe 7 can be fixed.

With the above-mentioned structure, the upper lid of the container of the filter 1 shown in FIG. 2 is taken out, the porous ceramics 3 for the purifying material is put therein, the filter 2 is put thereon, and the lid is put on the bath. The floating ring floats above the floating ring on the surface of the water in the bathtub, and expands and contracts due to sliding of the pipes 6 and 7 so that the bathtub 13 is expanded.
The pump 10 is settled at the bottom of the pump. The bath water 12 sucked from the suction port of the pump 10 is sent to the filter 1 through the pipes 7, 6, and 5, and the filter 2 removes scale, hair, dirt, and the like. As a result, dirt such as sweat is decomposed and removed, and water is constantly circulated and purified by pouring into the bathtub 13 through the discharge hole on the bottom surface of the filter 1. The device can be taken in and out of the bathtub by the filter 1
It can be easily put in and out with the handle of the lid.

In this embodiment, FIGS. 4 and 5, only the mounting method is different, and the circulating filtration method is all the same. FIG. 3 shows a method of fixing the filter 1 at a fixed position by using the floating ring 4 and the bathtub wall mounting plate 11.
By attaching the filter 1 to the inner wall of the bathtub above the water surface with the suction cup of the bathtub wall mounting plate 11, the space for bathing can be widened. FIG. 4 shows a method in which the rubber ring is inserted between the pipe 6 and the stopper screw 9 by using the floating ring 4 and the bathtub wall mounting plate 11 without using the stopper ring 9.
Is firmly fixed at a fixed length (the highest water level above the bottom of the bathtub), and the weight plate 15 is attached to the bottom of the pump 10 in order to stabilize itself by fixing the pump 10 to the bottom of the bathtub. Attach and use.

As described above, the present invention aims at saving water and saving heat energy by efficiently circulating and filtering the bath water and reusing the water efficiently with a small pump, and is small and inexpensive. Can be provided.
