Abstract

PURPOSE:To prevent a pump from being out of order by communicating a branch pipe with a circulating water course on the suction side of a jet bath pump, arranging the branch pipe in a state that water can be fed to a washing machine, providing the branch pipe with a residual hot water pump, and by setting the controller of the residual warm water pump in or near the washing machine. CONSTITUTION:When a residual warm water use starting switch 30 is operated at the time of using residual warm water, then a residual warm water pump 24 is started regardless of the state of a flow rate sensor 28, and pump jet water is fed to a washing machine 23 through a branch pipe 22. In this case, when water flow is generated in the branch pipe 22, then the flow rate sensor 28 is set in an ON-state. At the time of stopping the pump 24, the water level of the washing machine 23 comes to an upper limit value, and from a water level sensor 31, the output of OFF-command signal is generated, and the pump 24 is stopped, and then the water flow is stopped, and the flow rate sensor 28 is reset in an OFF-state. Besides, when the water level of the residual warm water comes to a value equal to or less than a specified value and air is infiltrated into the pump 24, then the water flow of the branch pipe 22 is stopped, and the sensor 28 is set in the OFF-state, and the pump 24 is automatically stopped.

(e) Function According to the present invention, the branch pipe only needs to be communicated and connected to the existing circulation waterway, and it is not necessary to provide a new connection hole in the bathtub or a water seal structure therefor. The connection structure becomes simple. In addition, since the remaining hot water is supplied to the washing machine through a permanently installed circulation waterway and branch pipes, it is possible to easily perform the operation without the need to insert or remove hoses, electric wires, etc. as in the conventional example. Further, when the remaining hot water in the bathtub decreases, the remaining hot water pump is stopped based on the detection signal of the flow rate sensor, thereby preventing breakdowns due to idle operation of the remaining hot water pump.
