Abstract

PROBLEM TO BE SOLVED: To effectively purify water when a body is submerged in a bathtub or the like and a centrifugal pump is stated by passing water through a filter formed in a curved surface along the peripheral surface of the body to filter off soil and then boosting the pressure of the filtrate by the centrifugal pump to pass it through ceramic base sterilizing filter mediums. SOLUTION: When purifying water in a bathtub, a water quality purifier body 1 is submerged in the bathtub and a centrifugal pump 6 is started. Then, the water sucked from a lower peripheral part of the device 1 passes through a filter 1b and goes out to a flow passage 1c. It is sucked from a pump suction port 6a and is sent out to a flow passage 1d from a pump discharge port 6b, and flows out to the side of a filter medium housing part If. At this time, the water passes through filter mediums 7a-7d and is purified. Further, it passes through filter mediums 7e, 7f to generate iron ions and improve cell active action, and also groups of colon bacilli, yellow staphylococcus and the like are sterilized to restrain water from spoiling. Then, the water is discharged from a discharge port 4.

The sliding piece 10a of the opening / closing mechanism 10 is inserted into a predetermined position on the main body side and pressed against the main body side so that the sliding piece 10a of the opening and closing mechanism 10 can be brought into close contact with the main body side.

[Effect] In the embodiment constructed as described above, the front cover 1a in which the filter 1b is mounted is mounted on the main body side, and the filter material 7 for purification is filtered into the filter material accommodating portion 1f by a predetermined amount. The material is stored and the lid 3 is closed, an air tube 4b is connected to a portion of the outlet 4a outside the outlet passage wall, and the free end of the air tube 4b is taken out of the bathtub to put the water purification device main body 1 into the bathtub. When the power is turned on by operating the on / off switch 5a of the operating device 5 by submerging, the centrifugal pump 6 is started, and the hot water in the bathtub is sucked and purification is started.

The hot and cold water sucked into the main body of the water purification device from the bath tub through the lower peripheral edge of the main body 1 flows into a flow passage formed in the cover via a protrusion 11 provided at the lower end of the front cover 1a. It enters, passes through the filter 1b, filters out large pollutants, and exits into the flow path 1c. Then, it is sucked in from the pump suction port 6a provided at the lower end of the flow path 1c, and is sent out from the pump discharge port 6b to the flow path 1d. The sent hot water flows from the flow path 1d through a hole formed in the center of the disk 1g, and flows out toward the filter material storage section 1f.

When flowing into the filter material storage section 1f, first, ions are removed through the filter material 7a, and ammonia components are neutralized by passing through the filter material 7b, odors are removed, and organic substances in water are removed. Removed and filter media 7c and 7d
To decompose protein- and starch-based contaminants, suppress the generation of slime, sediment organic matter floating in water, generate iron ions through filter media 7e and 7f, and activate cell activity. And kills coliform bacteria, Staphylococcus aureus, Bacillus subtilis, common bacteria, toxin-type and propagation-type bacteria, suppresses water decay and improves water quality.

All of the filter media 7a to 7 in the filter media storage section 1f
After passing through f to be purified, it flows into the outlet passage 3b formed in the lid 3 and is discharged from the discharge port 4. When the purified hot water is discharged from the discharge port 4, air is sucked from the free end of the air tube 4b by the negative pressure generated at the discharge port 4, flows out of the outlet 4a, and bubbles are generated in the purified hot water. Hot water containing air bubbles is discharged from the discharge port 4a.

As described above, by sucking up from the lowermost end of the water purification device main body 1 and blowing it out from the uppermost end, the dirt settled at the bottom of the bathtub is efficiently sucked,
Circulation purification of hot water can be efficiently performed from the bottom to the top of the bathtub. Further, since the filter 1b housed in the front cover 1a can increase the filter surface area,
The filtration area can be increased, and even if the sediment is filtered, the pressure loss does not increase and the suction performance does not significantly decrease. Efficiency can be improved. Furthermore, by forming the device into a pot shape and miniaturizing it, the occupying volume in the bathtub can be reduced, and a purifying device that is easy to handle and does not interfere with can be realized.

The centrifugal pump 6 does not allow the shaft 6e to penetrate the case 6c, so that there is no danger of liquid leakage to the electric circuit side, and a seal for preventing liquid leakage can be eliminated.
The filter material 7 for purification uses a plurality of filter materials 7a to 7f laminated and used, so that dirt removal, water purification, sterilization, and the like can be effectively performed, and the device capacity can be reduced by using an appropriate amount of filter material. it can. By forming the air suction type discharge port 4, air bubbles can be included in the discharged hot water, so that the purified hot water can be activated and a massage effect can be given to the body. .
