2. Description of the Related Art Regarding a system for circulating and purifying hot water in a bathtub, it is used as a ring for housing equipment as well as for improving the living environment for commercial use.
Various bath water purifying devices such as No. 2120 have been proposed. The problem with the circulation mechanism of hot water in the bathtub is that it removes the greasy particles and other contaminated solids from the human body that are attached to the filter layer of the purification device, and the greasy substances, E. coli, and other harmful bacteria dissolved in the bath water It is a means for purifying organic substances and the like.

The conventional purification device has a problem that the circulation purification action is deteriorated because it lacks the function of removing solid matters due to contamination of the filter layer and clogging. Further, no one having an effective purifying mechanism for removing pollutant harmful substances dissolved in bath water was found.

Conventional bath water circulation purification devices are generally large in size, and many existing bath baths require improvement work. Since the installation and construction costs are high, a purification device that can be easily installed at home is desired. It was

DISCLOSURE OF THE INVENTION The present invention relates to an improvement of the circulating bath unit of Japanese Patent Application No. 1-12120, which is an earlier application of the applicant, and is provided in a tank which should be called the heart of a water heater. In order to more effectively adjust the cleaning function of the filter and the filter material layer where the dirt and hair of the human body are contaminated during the hot water filtration and circulation of the hot water, the improvement of the water heater mechanism and the labor saving It is intended to be.

[Means for Solving the Problems] As a means for solving the problems, the present invention provides a ceramic first filter layer on the upper part of a tank, and a second filter layer made of porous stone aggregate particles on the lower part of the tank. A water heater device for circulating and purifying filtered hot water through a multi-directional switching valve between a bathtub and a body by providing a far-infrared heater and a foaming nozzle using magnetized air in a hot water chamber filtered through a partition plate. , Normally, hot water in the bathtub is poured from the upper part to the lower part of the tank to be filtered and circulated in the bathtub. When cleaning the tank, the hot water in the bathtub is allowed to flow backward from the lower part of the tank to wash the secondary filtration layer. And a circulating bath water heater provided so as to separately control the secondary back washing for washing the primary filtration layer.

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a pipe P is used to connect between a bath tub b shown in the drawing and a vessel body 1 equipped with a circulation filtration device.
The hot water HW in the bathtub is sent into the body through the water intake port b1 for purification, and then the purified and activated hot water is circulated again in the bathtub through the discharge port b2. This will be described in detail with reference to FIG. 1 as a circulation mechanism and operation during normal use. Specifically, the warm water HW in the bathtub is connected by the pipe P1 connected to the discharge port b2.
Is a multi-directional switching valve 4 which has a valve body provided with a flow path connection port in five directions and a switching valve which rotates in the valve body, and is opened and closed by a pipe connected to the upper part of the filtration tank 2 Water is poured into the filtration tank 2 via the valve V1.

The filtration tank 2 has an air vent valve 5 on the lower surface of the upper lid.
The inside of the tank is sealed in a vacuum. 6 is a 1st filtration layer, 7 is a 2nd filtration layer. The first filtration layer is a ceramic-filled filter, and the second filtration layer below the first filtration layer is filled with a large amount of porous furnace stone aggregate 7a and laminated to form a filtration tank together with the first filtration layer. The filter material 7a is a stone material of which the product name is called "Komeiseki" and which has water activity for filtration. Reference numeral 8 is a hot water chamber provided at the bottom of the filtration tank, 9 is a far infrared heater, which has a sterilizing effect, and the temperature of the hot water is adjusted by the sensor 10. The filtered hot water enters the multidirectional switching valve 4 again via the pipe P4, is connected to the pipe P2, and is circulated from the discharge port b2 to the bath b. At that time, the magnetized air generated by the air blow pump 11 and the magnetizer 12 is transferred to the pipe P2.
The hot water HW filtered through the valve V2 opened in the direction is pressed into the hot water HW and ejected as air bubbles into the bath b so that the hot water is sterilized and deodorized.

The water heater of the present invention performs circulation purification of hot water in the bathtub by means of an operation panel (not shown) equipped with a switch and a control device provided on the front surface of the body by the above-mentioned mechanism. The circulation action in the case where the purification is also carried out by automatic control is shown in FIGS. 2 and 3. FIG. 2 shows the primary cleaning of the water heater filtration tank, and FIG. 3 shows the circulation route of the secondary cleaning. If the first cleaning is shown in FIG.
The bathtub water absorbed from the pipe P1 and the compressor 3 has a valve path of the pipe P due to the rotation of the rotating body of the multidirectional switching valve 4.
4 and is backwashed upward from the lower part of the filtration tank 2 and at the same time magnetized air is supplied from the air blow pump 11 to the valve V2,
Open the pipe P3 and solenoid valve V3, and put the nozzle 13 into warm water.
The air bubbles are further pressed into the second filtration layer 7 to backwash the contaminants, and the sludge-like contaminants are discharged from the valve V4 and the valve path opened in the arrow direction of the multidirectional switching valve 4 through the pipe P5. Miscellaneous bacteria are discharged from the discharge port 14 to the outside of the device.

Next, the secondary cleaning will be described with reference to FIG. 3. Simultaneously with the primary cleaning, the bubble-injected hot water that flows backward from the lower part of the filtration tank 2 rises to the primary filtration layer 6 and the opening at the top of the tank. The contaminated water is discharged to the outside of the body from the discharge port 14 through the pipe P5 from the valve path of the multidirectional switching valve 4 opened in the arrow direction from the valve V1 (in this case, the valve 4 is closed).

[0011]

As described in detail above, the water heater of the present invention is effective for overhauling the water heater by cleaning and purifying the filtration tank, which was lacking in the conventional circulating water heater device. Hair and other contaminants remain in the layer, and the deodorizing action and sterilization are sufficiently achieved by forming the first filtration layer and the second filtration layer separately. Next, with regard to the water heater mechanism, the development of a multi-directional switching valve will make the primary and secondary cleaning operations quick and effective, and the internal labor-saving mechanism will be fully fulfilled. . Further, by activating the hot water in the bathtub by the cleaning action and improving the bactericidal action, the practical functional quality of the water heater device is enhanced, and it is extremely effective not only for the user but also for the comfort and health of the human body taking a bath.
