Therefore, the present invention solves the above-mentioned conventional drawbacks, and simultaneously filters two bath waters of different sizes and temperatures and adjusts the temperature with one filtration unit and heating means, without changing the bath water level of each. An object of the present invention is to provide a bathtub water filtering device that can be simply performed.

<Means for Solving the Problems> In order to achieve the above object, the bath water filtering device of the present invention is
A pair of outflow pipes for drawing out bathtub water from each of the two bathtubs, a common pipe line connecting the pair of outflow pipes, and a branch from the common pipe line again to return the filtered water to the respective bathtubs. A return pipe, and one common circulation pump and one common filtration unit are provided in the common line, and an opening / closing valve and a water amount regulator are provided in each of the pair of forward pipes and the pair of return pipes. When a water amount sensor is provided and both baths are circulated at the same time for filtration, the flow rate of the outflow pipe and the return pipe in each bathtub is determined by the water amount sensor and the water amount adjuster provided in the outflow pipe and the return pipe. The first feature is that the flow rate is set and adjusted to the same flow rate.

In addition to the first feature, the bath water filtering apparatus of the present invention is provided with a circulating water heating means in the common pipeline, and a temperature sensor is provided in each of the pair of outgoing pipes, so that both bath waters can be separately supplied. In the case of heating to the set temperature of, the temperature of each bath water heated by the circulating water heating means is detected by each of the temperature sensors, and when the temperature rises to the set temperature, opening / closing of the bath side to which the temperature sensor belongs The second feature is that the valve is closed.

<Operation> According to the first feature of the present invention described above, the bath water extracted from the two bathtubs passes through the outflow pipe, respectively, and then joins the common pipe line, and is filtered in the middle of the common pipe line. After being filtered by the unit, it is divided into respective return pipes and returned to the respective baths. Then, at this time, the flow rate of the forward pipe and the return pipe are adjusted by the water flow rate sensor and the water flow rate regulator provided in the forward flow pipe and the return pipe corresponding to the respective bathtubs to be the same flow rate. Even if the set circulation flow rates are different in the two bathtubs, the flow rates of the forward pipe and the return pipe on the respective bathtub sides are adjusted to the respective set flow rates by the water amount sensor and the water amount adjuster. By doing so, the amount of outflow and the amount of inflow match in each bath, and the water level is maintained. Further, the circulation amount can be set according to the size of the bathtub.

Further, according to the second feature of the present invention, when the bath water flowing through the common conduit is heated by the heating means, and as a result, the set temperature of one of the baths is reached, the temperature sensor on the bath side controls it. After detecting, the on-off valve on the bathtub side is closed and the circulation of water in the bathtub is stopped. The remaining bathtub is circulated when the bathwater is heated to the temperature set for the bathtub. When both on-off valves are closed, the circulation pump is stopped. Alternatively, the heating means is stopped. Of course, even when the heating is stopped and restarted, when the temperature drops to the temperature set for each bath, the open / close valve on the bath side is opened at that time, and heating is started. By doing so, the temperature of the two baths can be simultaneously controlled by one heating means.
