The priming suction pump has a suction member having an opening, and one end connected to the suction member via the suction pipe. A priming suction pump comprising a check valve device and a connection pipe communicated with the other end of the check valve device, wherein the check valve device is hollow and flexible. And a suction / discharge device for a circulating bath comprising a check valve provided at one end in the suction pipe direction and the other end in the connection pipe direction in the check valve storage member.

However, in both the bathtub filtering device structure described in Patent Document 1 and the suction and discharge device of the circulating warm bath described in Patent Document 2, the stored hot water before being filtered by the filtering unit passes through the manual pump mechanism. Because of this, the fat components of the human body contained in the hot water that cannot be removed by the filter installed at the tip of the water absorption pipe are gradually accumulated in the check valve (suction valve and discharge valve). There was a problem of causing clogging. In addition, because a gripping type is used as the manual pump mechanism, a large amount of priming water cannot be pumped at a time, and it is necessary to repeat the gripping operation many times in order to fill the circulation pump with priming water. There was also a problem that it took time.

Subsequently, the hot water reaching the upper part of one filtration tank 19 a moves to the other filtration tank 19 b via the connection pipe 27. And it moves from the upper part to the lower part in the other filtration tank 19b. During this time, bacteria and chlorine in the stored hot water are removed by the filter medium 23 of both the filtration tanks 19a and 19b.

  Next, the hot water that has passed through the filtration unit 10 passes through the convex pipe 35, passes through the drain pipe 4, and returns to the bathtub 2. At this time, both the suction valve 36 and the discharge valve 37 of the convex pipe 35 are opened by the flow of hot water.

  When the filter medium 23 is changed, the caps 22 of both the filtration tanks 19a and 19b appear by removing the lid 14 of the main body case 9, so that the used filter medium is removed from the exterior case 20 by removing the caps 22. The handle 31 is removed, the handle 31 is removed, the handle 31 is replaced with a new filter medium 23, and stored in the outer case 20.
