JPH11337184A - Bus adaptor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a bus adaptor where the exchange of an electrode can be performed easily, and silver ions can be used effectively, and also there is little possibility of corrosion of a circulation path. SOLUTION: For the building of an electrolytic unit into a bus adaptor, it is so arranged that an electrolytic unit cartridge 13 can be attached to and removed from a fixing male screw 14 by one touch. Hereby, at replacement of the electrolytic unit, the electrolytic unit cartridge can be replaced by the simple disassembly of the bus adaptor, so the work using a tool as in the past becomes needless. Therefore, the user can replace it easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath adapter for circulating bath water into and out of a bathtub.

[0002]

2. Description of the Related Art Hitherto, in a sterilizing and purifying apparatus and a bathtub with a water heater provided with a sterilizing and purifying function, the sterilizing and purifying function section has been built in the sterilizing and purifying apparatus or the bathtub with a hot water heater.

[0003]

However, when an electrolysis unit (for example, composed of a silver electrode) is built in a water heater as a sterilizing and purifying function unit as in the prior art, it is difficult to replace the silver electrode when it is consumed. There was a point. For example, replacement requires a tool, and it is extremely difficult for the user to replace, especially when the water heater is installed at a high place outdoors. In addition, there is a problem that the electrode size must be increased in order to eliminate the need for replacement (for example, not to consume for 10 years).

Furthermore, in the conventional method, the circulation path connecting the water heater (electrolysis unit) and the bus adapter and the circulation path such as the copper pipe inside the water heater have many opportunities to come into contact with silver ions, and silver ions adhere to copper. However, since silver was not used effectively for sterilization, much silver was needed. In addition, it is necessary to consider the amount of adhesion to copper, and it has been difficult to control the amount of silver dissolved to be constant. Furthermore, the possibility of corrosion of the circulation path by silver ions was high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. An object of the present invention is to make it easy to replace electrodes, to use silver ions effectively, and to reduce the possibility of corrosion in the circulation path. To provide a bus adapter.

[0006]

In order to achieve the above object, a first aspect of the present invention is a bus adapter provided at a connection between a circulation path for circulating bath water into and out of the bath tub and the bath tub. Since an electrolysis unit for sterilizing the bathtub water is provided inside, and the electrolysis unit is of a cartridge type, a user who is notified of the replacement time by a remote controller can easily replace the bathtub.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an overall configuration diagram when a bus adapter according to an embodiment of the present invention is applied to a bathtub with a water heater.

The electrolysis unit 10 is built in the bus adapter 1, and is supplied to the electrolysis unit 10 via a remote controller 9 having a control circuit for supplying a control voltage (control current) to the electrolysis unit 10. (Control current) is supplied. The replacement time of the electrolysis unit 10 is displayed on the remote controller 9 or notified by a buzzer. The electrode replacement time is determined based on the total time of power supply application or the value of current flowing between silver electrodes.

Further, silver ions generated by the electrolysis are immediately diffused into the bath water and consumed by sterilization of the bath water, so that the amount of silver ions in the bath water returning to the bath 4 with the water heater by circulation is small. Therefore, the amount of silver ions adhering to the circulation path such as the circulation pipe and the copper pipe in the water heater becomes small, and control for keeping the silver dissolved amount constant becomes easy. Furthermore, the possibility of corrosion of the circulation path by silver ions is reduced.

Further, in this embodiment, silver is used as an electrode in the electrolysis unit. However, a substance which generates ions by using an electrode of platinum, platinum iridium, copper or the like and has a sterilizing property may be used.

FIG. 2 is a configuration diagram of a bus adapter according to an embodiment of the present invention.

As shown in the figure, the bus adapter 1 is provided with a fixing male screw 14 through a hole formed in the bathtub 2 so that the connection body 1
5, the structure can be attached to the bathtub 2. The electrolysis unit is of a cartridge type, and contains a silver electrode therein. Then, the electrolysis unit cartridge 13 is mounted in the bus adapter 1 by attaching the electrolysis unit cartridge 13 to the fixing male screw 14 with one touch. The supply of the control voltage (control current) to the silver electrode in the electrolysis unit cartridge 13 is performed by the remote controller 9 through the power supply wire 16 and the electrode terminal 17. Further, floating dust and the like in the bathtub water are removed by the filter 11 provided in the bus adapter 1. In the present embodiment, the filter 11 such as a sponge is used to improve the performance of removing floating dust and the like, thereby improving the effect of sterilization by silver ions. Here, the supply of the control voltage (control current) is performed by the remote controller 9. However, a power supply unit such as a lithium battery and a control unit that controls the voltage (current) supplied from the power supply unit to the silver electrode are provided by an electrolytic It may be built in the unit cartridge 13 together with the silver electrode. In this case, the control voltage is always applied between the electrodes, but the current flows only when there is water in the bathtub, so that unnecessary current is not consumed. There is no need to provide an off switch. If the user thinks that sterilization is not necessary, the user only has to remove the cartridge.

As described above, when replacing the electrolysis unit, the electrolysis unit cartridge 13 can be replaced by a simple disassembly of the bus adapter 1, so that the replacement work using a tool as in the prior art is not required, and the user can easily do so. It is possible to replace it.
