DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath apparatus, and more particularly to a bath apparatus, in which hot water in a bath tub is forcibly circulated, while filtering, sterilizing, and other cleaning treatments are performed, and at the same time, the bath temperature is maintained at a bath temperature. The present invention relates to a so-called 24-hour bath apparatus which is capable of taking a bath at any time for 24 hours while keeping a bath at any time.

[0002]

2. Description of the Related Art In recent years, bathtub hot water purifiers have been actively used, in which hot water in a bathtub is constantly kept clean and at an appropriate temperature so that bathing can be performed comfortably 24 hours a day and water can be saved.

[0003] An example of such an apparatus for cleaning bath water is shown in FIG. 6, wherein 1 is a bath tub, 2 is hot water, 3 is a suction pipe for pumping hot water 2 in bath tub 1, and 4 is a hot water suction pipe. An apparatus main body in which devices for cleaning the hot water pumped up by the water suction pipe 3 are collectively provided, and 9 is a fountain pipe for ejecting the hot water treated by the apparatus main body 4 into the bathtub 1 again. .

A circulating pump 5 for forced circulation of hot water, an ultraviolet sterilizer 6 for sterilizing hot water,
In order to remove dirt from the hot water, a filter tank 7 loaded with various types of granular filter materials such as activated carbon, activated stones, and porous ceramic balls, or a fibrous filter alone or in combination, and a heat retaining heater 8 for maintaining the hot water at an appropriate temperature. And the like are disposed in series.

[0005] Reference numeral 10 denotes a prefilter attached to the end of the water suction pipe 3 for removing large dirt before being pumped to the apparatus main body 4. Reference numeral 11 denotes a jet flow of the hot water after the cleaning treatment as a high-speed jet flow in the bathtub 1. Suction pipe 1
Reference numeral 2 denotes a jet nozzle connected to the ejector unit.

An electromagnetic valve 13 for opening and closing a pipe is provided at the end of an intake pipe 12 connected to an ejector portion of the jet nozzle 11, and when the electromagnetic valve 13 is opened, the jet nozzle 1 is opened.
Air is sucked in from the intake pipe 12 by the suction force of 1, and the air is mixed into the hot water in the ejector section, and the air is jetted out of the jet nozzle 11 together with the hot water into the bathtub 1 to form a bubble bath.

[0007] In a conventional bathtub cleaning apparatus, ozone sterilization using an ozonizer, which is a small and inexpensive ozone generator, as a sterilizer has been widely used.

However, when ozone sterilization is performed in a bathtub hot water purifier, ozone sterilization must be stopped at the time of bathing in order to prevent bathers from inhaling ozone scattered from the hot water and causing harm to health. Also, if ozone sterilization is performed at midnight, there is also a problem that sleep noise is disturbed by an intake sound and radio interference is caused to an electric appliance such as a TV.

Therefore, recently, an ultraviolet sterilizer has been increasingly used as a sterilizer in a bathtub cleaning apparatus.

When the ultraviolet lamp is in direct contact with the circulating bath water when using an ultraviolet sterilizer in the bath water cleaning device, there is a danger of electric leakage due to the intrusion of the water unless the lamp is completely waterproof. Since the material is heated to a high temperature, the temperature difference from the hot water is large, and there is a possibility that the material is broken by a heat shock.

For this reason, in the ultraviolet disinfection device in the bathtub hot water cleaning device, the ultraviolet lamp is housed in a protective tube made of quartz glass or the like, which is made of a material having a transparent outside, good ultraviolet transmittance, and excellent heat resistance. The direct contact is cut off, and the ultraviolet lamp housed in the protective tube is housed in a jacket through which hot water flows.

FIG. 7 shows an example of an ultraviolet sterilizer used in the bathtub hot water purifier as described above. The jacket 14 is provided with a hot water inlet 15 and a hot water outlet 16, and an opening at an upper end is provided. It is closed with a jacket lid 17 and is made of metal or plastic.

Reference numeral 19 denotes an outer tube as a protective tube for an ultraviolet lamp made of glass having a good ultraviolet transmittance such as quartz. The outer tube 19 has an O-ring of an O-ring in a mounting hole 18 provided at the center of the jacket lid 17. General packing 20 like
It is fitted and attached while sealing with no leakage.

An ultraviolet lamp 21 is inserted into the outer tube 6, and an ultraviolet lamp 21 is provided in the jacket 14.
The outside is covered with an outer tube 19 so that it does not come into direct contact with water, and is protected from cracking due to a temperature difference.

The ultraviolet lamp 21 is of a straight tube type and has electrodes 22 and 23 opposed to each other at both ends.
4 and at the same time, a nickel-plated wire 25 that can be soldered is drawn out from the electrode 22 on the lamp base 24 side.
The nickel wire 25 drawn from the electrode 22 on the lamp base 24 side and the bare wire 26 from the electrode 23 on the tip side are connected to the lead wire 27 having a female connector 28 attached to the tip at a recess in the lamp base 24. And is molded with steatite or the like together with the lamp end face.

Reference numeral 29 denotes an inverter board.
A circuit for applying a high-frequency high voltage for discharge to the opposite electrodes 22 and 23 of the ultraviolet lamp 21 based on the control by 0 is formed, and a lead wire 31 having a male connector male attached to the end extends.

Reference numeral 33 denotes a mounting plate for fixing the ultraviolet sterilizer. In this example, the mounting plate 33 extends from the upper end of the jacket 14 and the jacket lid 17 is fixed to the mounting plate 33 with a plurality of screws 34. ing.

The lead wire 31 from the inverter board 29 penetrates through the mounting plate 33 and emerges upward. Therefore, the ultraviolet lamp 21 moves the female connector 28 of the lead wire 27 to the male connector 32 of the lead wire 31 on the mounting plate 33. Is connected to the inverter board 29 by being fitted above the.

By the way, the ultraviolet lamp 21 also has a service life similar to that of a general light bulb, although it varies depending on its light emitting method. The hot cathode type is a half to two years, and the cold cathode type is several years. The intensity of the ultraviolet light is weakened, and the life span is shortened, and the replacement must be performed.

In accordance with the method described in the instruction manual of the apparatus, the ultraviolet lamp 21 is first turned off, and then the male and female connectors 28 and 32 are disengaged and the lead wires 27 and 3 are disconnected.
After disconnecting the lamp 1, the ultraviolet lamp 21 is pulled out of the outer tube 19 and replaced.

[0021]

However, in the conventional apparatus, when the ultraviolet lamp 21 is replaced, there is a danger that the replacement person may get an electric shock or damage his eyes and skin.

The reason is that the lead wires 27 and 31 are long in the conventional device, and the lead wire 31 is attached to the mounting plate 33.
The connectors 28 and 32 of the male and female connectors are not fixed to the
The UV lamp 21 can be connected to the outer tube 1 without disengaging
This is because the UV lamp 21 may be replaced freely without disconnecting the power supply and without disengaging the male and female connectors 15 and 19 without following the instruction manual.

In other words, if the male and female connectors 28 and 32 are disengaged or mated without turning off the power, there is a risk of electric shock, and the male and female connectors 28 and 32 are fitted without turning off the power. If the ultraviolet lamp 21 is pulled out from the outer tube 19 or inserted again while the ultraviolet lamp 21 is being lit, the eyes and skin may be damaged by direct exposure to strong ultraviolet rays.

The present invention solves the above-mentioned drawbacks of the prior art, and cleans a bathtub provided with an ultraviolet sterilizer capable of being replaced safely and safely without causing an electric shock to an ultraviolet lamp or damaging eyes or skin. It is an object to provide a chemical conversion device.
