[Means for solving problems]
Therefore, as a result of repeated diligent research, the inventor introduced the invention by using a circulation pump that pumps bath water from a bathtub, a filtration tank for filtering impurities such as fine dust and dirt from the bath water, and the bath water. In a bath water circulation device consisting of a heater that heats from a low temperature to a high temperature, a circulation pipeline that purifies the bath water with a sterilizer that sterilizes the bath water, and returns the bath water to the bathtub, the bath water circulation apparatus is provided in the outflow side conduit of the circulation pipeline. A cleaning valve, a connecting pipeline that connects one end to the cleaning valve and the other end to an appropriate location on the suction side of the circulation pipeline, and an appropriate location on the outflow side circulation pipeline of the circulation pump. The drain valve and the drain valve, one end of which is connected to the drain valve to drain the bath water to the outside of the bath, are connected to the drain valve. One end of the pipeline for returning water is connected, and a ejection portion for discharging bath water to the bathtub is provided at the other end. When the bath water is drained, the washing valve is driven to discharge the bath water in the bathtub from the ejection portion. By using a bath water circulation device or the like characterized by sucking in hot water, hot water can be safely and surely drained even if the pre-filter is clogged during drainage after hot water drainage. Is the solution.

【Effect of the invention】
First, the invention of claim 1 has an extremely excellent effect that even if the pre-filter or the like is clogged, hot water can be reliably mixed with bath water to lower the temperature and then safely drain the water. Has. That is, when the bath water is drained, the cleaning valve V2 is driven so as to suck the bath water in the bathtub 10 from the ejection portion 11, mix it with the hot water in the circulation pipe 14, and discharge it to the outside of the bathtub 10. As a result, in the cleaning valve V2, the hot water (or bath water) that has flowed in from the pipeline a has sufficient suction power of the circulation pump P, so that all the hot water (or bath water) flows out to the connecting pipeline b without flowing out to the pipeline j. be able to.

Further, since the suction force of the circulation pump P also reaches the pipe line j, the bath water in the bathtub 10 can be sucked up through the pipe line j. As a result, a sufficient amount of bath water in the bathtub 10 can be sucked up by the ejection portion 11, and can be mixed with hot water (or bath water) passing through the circulation pipe 14, so that a prefilter or the like can be used. Even when it is clogged, it has an extremely excellent effect that hot water can be reliably mixed with bath water to lower the temperature and then safely drained.

Further, in the invention of claim 2, in the first aspect of the present invention, a pipeline purification device in a bath water circulation device in which _{an opening / closing valve V 3 that can open and close the pipeline is provided at an appropriate position on the circulation pump P side of the suction unit 12.} As a result, the following excellent effects are produced.

_{That is, by providing the opening / closing valve V 3} that can open and close the pipeline at an appropriate position on the circulation pump P side of the suction portion 12, the pipeline m or k can be opened regardless of whether the prefilter is clogged. Opening and closing control can be performed reliably. Therefore, if the on-off valve V ₃ is closed, the pipeline m or k is surely closed. Therefore, when the pre-filter is clogged or the like and only a halfway amount of bath water can be sucked up, the on-off valve V ₃ is closed. As a result, the bath water in the bathtub 10 can be sucked only from the ejection portion 11.

As a result, a sufficient amount of bath water in the bathtub 10 can be sucked up only by the ejection portion 11, and can be mixed with hot water passing through the circulation pipe 14, so that even when the pre-filter or the like is clogged. In addition to the excellent effect according to the invention of claim 1, it has an extremely excellent effect that hot water and bath water can be mixed more reliably to lower the temperature and then drain the water more safely.

The invention of claim 3 has an extremely excellent effect that even when the pre-filter or the like is clogged, it can be reliably controlled so that hot water and bath water are mixed to lower the temperature and then drained safely. Have. That is, the cleaning valve driving means 23c controls the driving of the _{cleaning valve V 2} so that the bath water in the bathtub 10 is sucked from the ejection portion 11 and the suction portion 12 when the bath water is drained. In the valve V ₂ , the hot water (or bath water) that has flowed in from the pipeline a has sufficient suction power of the circulation pump P, so that all the hot water (or bath water) does not flow out to the pipeline j but is surely discharged to the connecting pipeline b. Can be done.

Further, since the suction force of the circulation pump P also reaches the pipe line j, the bath water in the bathtub 10 can be reliably sucked up through the pipe line j. As a result, a sufficient amount of bath water in the bathtub 10 can be reliably sucked up from the ejection portion 11, and the hot water passing through the circulation pipe 14 can be reliably mixed, so that the pre-filter and the like are clogged. Even when it is used, it has an extremely excellent effect that hot water and bath water can be mixed to lower the temperature and then drain the water safely and surely.
