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 bath water is adjusted to a bathing temperature while simultaneously purifying water such as filtration and sterilization while forcibly circulating hot water in the bathtub. The present invention relates to a so-called 24-hour bath apparatus which is kept clean and at an appropriate temperature so that a user can take a bath at any time for 24 hours.

[0002]

2. Description of the Related Art Recently, a bathtub hot water purifying apparatus, that is, a 24-hour bath, which constantly keeps hot water in a bathtub clean and at an appropriate temperature, enables comfortable bathing for 24 hours, and saves water, has been actively used. It has become.

One example of such a bathtub hot water purifier is shown in FIG. 5, wherein 1 is a bathtub, 2 is hot water, 3 is a water suction pipe for pumping hot water 2 in bathtub 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. .

In order to remove dirt from the bath water, a filter tank 5 containing various types of granular filter media such as activated carbon, activated stones, and porous ceramic balls, and a fibrous filter is used. A cleaning device such as a circulation pump 6 for forcibly circulating hot water, an electric heater 7 for heating hot water, and an ozonizer 8 as a sterilizing device for hot water is provided. It should be noted that other sterilizers include an ultraviolet sterilizer using a UV lamp, but in the present invention, a sterilizer using an ozonizer will be described.

[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.

A solenoid 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 an ozonizer 8 is provided on the way. When the solenoid valve 13 is opened, the jet nozzle 11 is opened. Air is sucked from the suction pipe 12 by the suction force of the air, this air is mixed into the hot water at the ejector section, and a jet stream is jetted from the jet nozzle 11 into the bathtub 1 to form a bubble bath. The air sucked into the bath is ozonized and jetted into the bathtub 1 to sterilize the hot water 2 with ozone.

[0007] Accordingly, the hot water 2 in the bathtub 1 passes through a cleaning pipe 14 from a water suction pipe 3 having a pre-filter 10 attached to a tip thereof to a hot water pipe 9 having a jet nozzle 11 attached to a tip thereof through a circulation pump 6. , And a predetermined cleaning process such as filtration, sterilization, and hot water temperature adjustment is performed.

[0008]

However, in the conventional apparatus, as the operation is continued, dirt is attached to the cleaning pipe, and when a large amount of dirt is attached to the cleaning pipe, the pipe becomes narrow and the flow of hot water becomes poor. And the ability of cleaning is reduced.

Therefore, if the flow of hot water deteriorates due to the contamination of the cleaning pipe, the pipe must be washed with a considerable amount of time and the pipes must be replaced.

It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide an apparatus for cleaning a cleaning pipe without any hassle and keeping it constantly clean.

[0011]

That is, the present invention relates to a filter tank for pumping hot water in a bathtub from a suction pipe with a circulation pump,
