Patent No. 4399512 gazette

Patent Document 1 discloses a purification method in which fungi are not proliferated by removing and washing a filtration filter on which sebum and waste products form filtration residue and adheres to it every day for up to 3 days.
However, there are cases where even once filter washing is performed every day from 3 days a day, it is not easy to carry it out, or it can not be done due to aging, which is an issue to be solved.

As long as a household circulating hot water bath is used, the work of cleaning filter residue adhering to the filter can not be omitted.

The present invention alleviates the trouble by the method of backwashing the filter, and copes with the aging of the user without deteriorating the quality of the bath water even if the circulation filtration is continued for a long time. The

The basic structure of a circulating water bath is constructed so that the rotational power of a motor pump sucks and filters the bath water from the water inlet, and heats it with a heating heater to perform a circulation function to return it from the water outlet to the bathtub. ing. As a general method of setting the flow direction of the water absorption and the discharge as a forward flow and making the flow backward, the rotation of the motor pump is temporarily stopped and then the rotation direction is reversed. However, in the present invention, the forward flow is instantaneously converted to the reverse flow without stopping the motor pump and changing the rotation.

The present invention is to increase the filtration efficiency of the impurities in the bath water by circulating the whole of 250 to 300 liters of the bath water of a general household bath and forcibly permeating the filter, but the filter residue to be adhered is The present invention provides a home circulating hot water bath employing a backwash method in which the user does not have to wash the filter in the process.

The household circulating hot water bath of the present invention has a bath and a filtration filter for filtering bath water circulating from the water inlet to the water outlet in the bath, and filters bath water flowing from the tank inlet to the tank outlet. A filtration tank, a circulation pump for drawing the bath water from the pump suction port and delivering it to the pump discharge port, a heating heater for heating the bath water flowing from the heater inlet to the heater outlet, a drain outlet for discharging the bath water; A reversing valve is provided to switch the flow path of the bath between the first and second switching states, and when the reversing valve is in the first switching state, from the bath, the reversing valve, the tank inlet of the filtration tank, the tank The first flow path (forward flow) (return flow to the bath through the outlet, reverse valve, pump inlet of circulation pump, pump outlet, heater inlet of heating heater, heater outlet, reverse valve) in this order And when the reversing valve is in the second switching state, from the bathtub, reversing valve, tank outlet of filtration tank, tank inlet, reversing valve, pump inlet of circulation pump, pump outlet, heating heater Through the heater inlet, the heater outlet, and the reverse valve to form a second flow path (backflow) to the drain outlet.
Further, in the domestic circulating hot water bath apparatus of the present invention, a filter in which an activated carbon filter is wound around a porous cylinder provided with elastic packings in the upper and lower parts and slightly longer than the depth of the filtration tank When the filter was inserted and the filter tank lid was firmly closed, the upper and lower elastic packings were in a narrowed state so that the entire amount of bath water flowing into the filter tank was forced to permeate the filter.

As a result, filtration residue adheres to the filtration filter which filtered out the impurities in the bath water daily. Therefore, if cleaning is not carried out, clogging will occur and the permeation will deteriorate, so that the flow direction of the bath water is reversely flowed for a certain period of time every single day or several days, and filtration residue adheres to the filter with flow pressure from the opposite direction. After exfoliating and removing it out of the bath, it is restored to the state of filtration under normal flow again. This prevents the user from having to wash or replace the filter for an extended period of time.

In order to have such a structure and function, it is necessary to devise a reverse valve capable of instantaneously reversing the flow direction without stopping the operation of the circulation pump.

The structure of the reversing valve for switching the flow direction incorporates a reverse flow switching board provided with a forward flow path and a reverse flow path inside, rotates the reverse flow switching board to a designated fixed position, and the rotation of the circulation pump is still in use. By switching the forward flow path to the reverse flow path, the reverse flow is realized.

In the present invention, there is no need for daily bath washing and bath watering, and in addition to the convenience of being able to take a bath 24 hours a day, bathing also swells blood vessels by bathing and a lot of heated blood flows to carry oxygen and nutrients to cells of the whole body and metabolism. Promote. And the thermal shock that you feel in bathing increases heat shock protein in the body and enhances self-healing ability and immunity to create the basis of health. Spreading as a health promotion device for that purpose will contribute to the health and longevity of middle-aged and elderly people. Therefore, the number of filter filter washings in Patent Document 1 is reduced to improve convenience and extend the spread to middle-aged and elderly households not only to extend the health life of the elderly but also to consume by daily bath boiling Control the amount of CO2 emitted from fossil fuels and exert a great effect on preventing global warming.
