DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a bathing device, and its purpose is not only to keep the bathing device clean at all times during bathing, but also to make it possible to use the remaining hot water once used for bathing in the next day. Not only can it be recycled and used over and over again, saving water resources and energy, but it also reduces water charges and costs for users.
The purpose of the present invention is to provide a bathing device that can achieve economical savings such as reduction of natural expenses.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

In the figure, 1 is a bathtub, 2 is a circulation flow path, one end of which is the bathtub 1.
At a low position such as the bottom surface or the lower part of the side wall, it communicates with the bathtub 1 and serves as a flow passage inlet, and the other end communicates with the bathtub 1 at a high position such as the upper part of the side wall of the bathtub and serves as a flow passage outlet.

This circulation channel 2 is equipped with a pump 3 on the way, and the operation of the pump 3 forces the hot water in the bathtub 1 to circulate through the circulation channel 2, and the upstream side of the pump 3 is is equipped with a filtration device 4 and a sterilization device 17 to filter and sterilize circulating hot water.

For convenient cleaning and replacement of filter media, the filtration device 4 is installed in the bathtub 1 as shown in FIG. Provided on the outer surface.

When the filtration device 4 is installed in the bathtub 1, as shown in FIGS. 2 and 3, a cylindrical partition wall 6 is provided at the center of the inner bottom surface of a main body 5 in the shape of a circular cap with one side open. The outflow chamber 7
The outer side is an inflow chamber 8, and the two chambers 7 and 8 are communicated by opening holes 9 at appropriate intervals in the circumferential direction of the partition wall 6, and the epithelial membrane inflow chamber 8 is provided with an inflow chamber 8. For example, a filter medium 10 such as polyurethane foam is filled.

Note that notches 11 are formed at appropriate intervals along the circumferential direction of the opening edge of the main body 5, and the filter medium 10 is packed deeper into the notches 11.

In this filtration device 4, the opening of the outflow chamber 7 is connected to the inlet of the circulation channel 2 via a fitting 12 provided on the inner surface of the tank wall 1' of the bathtub 1, and the inlet chamber 8 is connected to the inlet of the circulation channel 2. The opening of the main body 5, that is, the opening end of the main body 5 has a certain amount of clearance 13 with the tank wall 1' of the bathtub 1.
It is detachably attached to the inner surface of the tank wall 1' of the bathtub 1 so as to have the following features.

That is, the opening of the inflow chamber 8 and the opening of the outflow chamber 7 constitute an inlet 27 and an outlet 28 of the filtration device 4, respectively. The opening end of a pipe 2 constituting a circulation flow path 2 is fitted in a watertight manner in the part of the bathtub 1 that projects outward, and the outflow chamber of the filtration device 4 is fitted in the part that projects inward of the bathtub 1. The opening 7 is screwed or fitted.

Further, when the filtration device 4 is installed on the outer surface of the boiler 26, the inlet chamber 8 is provided as shown in FIGS. 6 and 7.
The cylindrical partition wall 6 that partitions the inflow chamber 8 and the outflow chamber 7 is formed integrally with the cover plate 14, and there is a gap between its tip and the inner bottom surface of the main body 5. The chambers 7 and 8 are in communication with each other through the clearance 15.

Further, an inlet 27 communicating with the inflow chamber 8 and an outlet 28 communicating with the outflow chamber 7 are opened in the lid body 14 .

The cover plate 14 is directly fixed to the outer surface of the boiler 26, and the pipe 2 constituting the circulation flow path 2 is connected directly to the boiler wall surface 26.
An inlet 27 and an outlet 28 opened in the cover plate 14 by penetrating through 6'
The inflow chamber 8 is connected to the upstream side of the circulation channel 2, and the outflow chamber 7 is connected to the downstream side.

Further, the filter medium 10 is filled into the inflow chamber 8 so as to have an appropriate gap 16 between the filter medium 10 and the cover plate 14 .

The main body 5 is detachably attached to the cover plate 14 by screwing or fitting.

The sterilizer 1T has a cylindrical body 19 having a through hole 18 in the axial direction, and a pair of electrodes 20 made of a silver plate on the hole wall of the through hole 18.
20 are arranged in a relative manner, and the through hole 18 is interposed in the middle of the circulation flow path 2 so as to constitute a part of the flow path.

That is, a part of the pipe 2' constituting the circulation flow path 2 is cut off, and the cut ends are screwed into both ends of the through hole 18, respectively.

Further, the electrodes 20, 20 are linked to the pump 3,
The power is turned on in synchronization with the start of pump 3 operation, and pump 3
Configure it so that the power is turned off in synchronization with the stoppage of operation.

In the bathing device of the present invention configured in this way, when the pump 3 is operated and the hot water in the bathtub 1 is circulated through the circulation flow path 2, the hot water is filtered by the filtration device 4 to remove dirt, dust, and waste water. Floating foreign matter such as hair is removed, and at the same time, the silver electrodes 20, 20 of the sterilizer 17 are energized in synchronization with the pump operation, and silver is dissolved in the water by electrolysis, forming a sterilizing concentration of dissolved silver ions. , continuous sterilization in water and prevention of bacterial growth.

Therefore, the hot water flowing through the circulation channel 2 returns to the bathtub 1 as clean hot water, and by continuing to circulate the hot water for a certain period of time, the hot water in the bathtub 1 used for bathing can be regenerated. .

In addition, 21 is a thermistor provided in the circulation flow path 2 downstream from the pump 3, and 22 is a heating flow path that is separated from the circulation flow path 2 between the pump 3 and the thermistor 21 and communicates with the bathtub 1. The flow path 22 is provided with a valve 23 and a heating device 24 in the middle thereof, which are linked to the thermistor 21 and open when the hot water flowing through the circulation path 2 becomes lower than a set temperature and close when the temperature reaches a high temperature. ing.

When the temperature of the hot water flowing through the circulation channel 2, that is, the temperature of the bath, falls below a certain temperature, a part of the hot water flowing through the circulation channel 2 flows into the heating channel 22, and is heated by the heating device 24. The heated water returns to the bathtub 1 and raises the temperature of the hot water in the bathtub 1 to the set temperature.

Although the heating device 24 is not shown, it is possible to use a device that heats hot water supplied from the water supply to a hot water mixing faucet or a shower.

Moreover, 25 is a high frequency generator provided at the flow path outlet of the circulation flow path 2.

The sterilizer 1γ, pump 3, thermistor 21, valve 23, and heating device 24 are all incorporated into the boiler 26.

Therefore, when the bathing device of the present invention is used to reboil the same water for three days and taking a bath, changes in the turbidity of the water and the number of bacteria can be compared to conventional bathing devices that do not have a filtering device or a sterilizing device. When compared with the apparatus, the results were as shown in the graphs shown in FIGS. 8 and 9.

As is clear from the graph above, in the conventional bathing device, both the turbidity and the number of bacteria increase significantly over time, whereas in the bathing device of the present invention, the turbidity and the number of bacteria increase even when bathing in the third pewter. The number of bacteria has hardly changed since the first white of the bath, and the bath maintains a sufficient degree of cleanliness.

Therefore, you can take a bath for 3 or more days without changing the water every day, and you can save a lot of water, and you can also save on water and sewerage fees. .

In addition, if you compare the boiling time when you boil a bath once using the bathing device of the present invention and then reboiling it the next day, and when you replace and boil the water in the bath using a conventional bathing device, the boiling time will be as shown in the table below. (The time to add water is included in the boiling time) From the above results, it can be seen that if you boil a bath once and then reboil it the next day, the boiling time will be significantly shorter than if you boil a bath with fresh water.

Therefore, if you use the bathing device of the present invention to re-boil the water in the bathtub and use it for 2-3 days or more, it is no longer necessary to change the water in the bathtub every day and take a bath using the conventional bathing device. The time it takes to boil water every day is significantly shorter than the previous one (as a result, the amount of fuel used naturally decreases, resulting in energy savings and fuel cost reductions).

Furthermore, since the bathing device of the present invention is equipped with a filtration device and a sterilization device upstream of the pump in the circulation flow path, even if a water leak occurs at the attachment point of the filtration device and sterilization device, the chain can be easily removed. Since the flowing hot water is sucked by the pump, there is no inconvenience such as blowing out from the above-mentioned locations.

Moreover, since the filtration device is attached to the inner surface of the bathtub or the outer surface of the boiler, it is easy and convenient to replace the filter medium, and the inflow chamber and outflow chamber are located inside the cap-shaped main body, the former being on the outside and the latter on the inside. The inflow chamber is filled with a filter medium, and the two chambers are connected to each other at a position close to the top surface of the main body. Since an inlet that communicates with the outflow chamber and an outlet that communicates with the downstream side of the flow path are provided on the mounting surface side of the main body, it can be formed into a thin and flat shape, so it can be installed inside a bathtub, etc. (The resistance when the hot water passes through the filter material is small, and a small pump can be used.)

Furthermore, the sterilizer includes a cylindrical body having a through hole in the axial direction, and a plate-shaped silver electrode is disposed relative to the hole wall of the through hole along the hole wall so as to form a road surface shape with the hole wall. Since it is interposed in the middle of the flow path so that it forms part of the flow path, it does not create resistance in the flow path and does not obstruct the flow of circulating water. A pump can be used.
