弁（導入弁）は極めて近い位置に設けられていた。In the bathtub connection device for forced circulation disclosed in these documents, two valves (introduction valve) are provided at a place (front surface) where hot water flows from the bathtub into the bathtub connection device for forced circulation. In addition, two valves (discharge valves) were also provided at locations where the hot and cold water was discharged from the bathtub connection device for forced circulation into the bathtub (outer peripheral portion). Further, the two valves (introduction valves) are provided at extremely close positions.

クルを生じる。However, when the above-mentioned valve (introduction valve) is made of a rubber material and deteriorates to cause a crack or the like, or when the above-mentioned valve (introduction valve) is caught by dust such as hair, Hot water is discharged from the deteriorated valve (introduction valve) into the bathtub. Therefore, the discharged hot and cold water is immediately returned to the forced circulation bathtub connection device from the other open valve (introduction valve) provided near the deteriorated valve (introduction valve). A so-called short cycle occurs.

しまうといった問題点を有している。When such a short cycle occurs, hot water heated by the forced circulation water heater is
Circulation is performed between the forced circulation bathtub connection device and the forced circulation water heater. Normally, a thermistor for detecting the temperature of the circulating hot and cold water is provided on the forced circulation hot water supply side, and the hot water temperature is detected by the thermistor. As described above, the temperature of the hot water circulated by the short cycle is higher than the temperature of the hot water in the bathtub. When the hot water temperature is detected by the thermistor, the hot water temperature is controlled by the control device connected to the thermistor. As a result, it is determined that the set hot water temperature has been reached, and the hot water circulation pump is automatically stopped. Therefore, there is a problem that it is determined that the temperature of the hot water in the bathtub has not reached the set temperature, but the optimum temperature (set temperature), that is, the bath is determined to be boiling even though it is not.

The hot water opens the partition plate 34 by the water flow and flows into the return hot water passage 30. From the return hot water passage 30, the through-hole 34 (not shown), the cylindrical portion 36 of the connection receiver 15 and the cylindrical portion of the main body 14 are formed. Through the space passage 43 of the connecting member 6, the water is returned from the connecting portion 5 to the return connection pipe (not shown) and the forced circulation water heater (not shown). At this time, the on-off valve 33 is closed by the suction force.
