Abstract

PURPOSE:To effectively filtrate and circulate warm water in a bathtub to purify and activate it by normally filtrating warm water sucked from a bathtub before sterilizing and returning it and, in backwashing, washing and rinsing a tank filter. CONSTITUTION:Normally, after warm water in a bathtub 2 is sucked and caused to flow from above to below in a tank filter 4 and filtered, it is introduced into a warm water heater 13 from is lower part, and simultaneously ozonized air is blown into the warm water heater 13 from an ozonized air magnetizer 20 to sterilize and activate the warm water, which is returned to the bathtub 2. Next, when scale and organic matter are stuck on a filter medium in the tank filter 4, the warm water sucked from the bathtub 2 is introduced into the tank filter 4 from its lower part, and ozonized bubbles from the ozonized air magnetizer 20 are mixed with the warm water during that time to backwash the filter, and the warm water is discharged to outside of the filter. Then, the warm water from the bathtub 2 is introduced into the tank filter 4 from its upper part, and passed through the filter 4 and the residue is discharged to outside of the filter from its lower part, to rinse the filter. After that, normal circulation is restored.

[0004]

As a circulation means for solving the above object, hot water in a bathtub is passed from an upper portion to a lower portion of a filtration tank in a circulation filter to clean it, and then an air blow by an ozone air magnetizer is mixed. Adjusting the temperature with a hot water heater and returning the purified purified hot water to the bath again with normal circulation means and removing contaminants adhering to the filter media in the filtration tank in the circulation filter, and sterilizing by mixing with an air blow by an ozone air magnetizer. Backwashing means for backwashing from the lower part of the filtration tank to the upper part and discharging it outside the bath, and further a means method by combining with a rinse purifying means for discharging the residual pollutant residue after cleaning by normal circulation to the outside of the bath. As the constitution of the above means method, a filtration tank in which a casing is filled with a filter medium and a hot water heater provided with an adjusting mechanism are provided inside the filtration circulator. Built in, and between them, a 5-way switching control valve pipe-connected to the bath via a circulation pump and an ozone air magnetizer connected to the hot water heater were installed, and each of the above mechanisms was compactly set in the circulator. The present invention relates to a filtration circulator device.

[0005]

[Operation] Normal circulation operation: Purified hot water obtained by filtering the hot water sucked from the bathtub by the circulation pump from the upper part of the filtration tank to the lower part by the 5-way valve is again guided to the lower part of the hot water heater by the 5-way valve and simultaneously ozoned by the ozone air magnetizer. Air is blown into the hot water heater to sterilize and activate the hot water to flow back into the bath.

[0006] Backwash circulation operation: Warm water sucked from the bathtub is mixed with ozone bubbles from the ozone air magnetizer at the upper part of the filtration tank from the lower part of the filtration tank through the switching control valve to perform backflow cleaning and then through the five-way valve again. Guide it to the drain pipe and discharge it outside the bathtub.

Rinsing and washing action: Hot water sucked from the bath is passed through the five-way valve from the upper part of the filtration tank to the inside of the tank, and the residue is guided from the lower part of the filtration tank to the drain pipe and discharged to the outside of the bath. After rinsing and washing, switch the 5-way valve to return to normal circulation.

[Effect] Since the present invention is a warm water circulator using the above method and apparatus, at the same time as removing residual contaminants by rinsing and cleaning, ozone air generated by the ozone air magnetizer is warm water purified by the filtration tank during normal circulation. Since it is mixed with ozone air in the vessel and blown, it decomposes and activates ammonia and nitrous acid in warm water by the oxidizing power of ozone magnetized bubbles and aeration in water, and returns to the bath as warm water with a sterilizing effect of ozone. However, when backwashing, the backflow in the filtration tank is carried out and the scale and organic matter adhering to the filter medium are decomposed into proteins and normal hexane by the action of ozone magnetizing bubbles, and the oxides are adsorbed and discharged at the interface of the bubbles. It is effective for the purification of water and the treatment of warm water with white turbidity. In particular, ozone air bubbles generated by an ozone air magnetizer have a strong oxidative power and a sterilization rate of 90% compared to 10% to 20% of a conventional filtration device that does not use ozone air bubbles.
It has a sterilization rate of ~ 100%, and ozone air bubbles have a novel action of self-decomposing without leaving secondary pollutants to generate oxygen to generate active water and to dissolve dissolved oxygen in warm water. The effect is great together with the cleaning.
