JPH03159689A - Equipment for using residual warm water of bath - Google Patents

Abstract

PURPOSE:To simplify mechanism and operation by communicating a branch pipe with a circulating water course on the jet side of a jet bath pump, arranging the branch pipe in a state that water can be fed to a washing machine, and by setting a controller for controlling the feed water of the branch pipe, in or near the washing machine. CONSTITUTION:When a jet operation switch 21 is ON-operated at the time of taking a jet bath, then a jet bath pump 16 is started, and water mixed with bubbles is jetted from a nozzle section 19. When a feed water starting switch 27 is operated at the time of using residual warm water, then the pump 16 is started and at the same time, a solenoid valve 26 is opened, and the jet water of the pump 16 is fed to a washing machine 23 through a branch pipe 22, and after that, at a time point when the water comes to a specified water level, the pump 16 is stopped based on the command signal of a water level sensor 28 and at the same time, the valve 26 is closed. Besides, at the time of using the residual warm water, the pump jet water flows to the side of the nozzle section 19, but the passing resistance of the nozzle section 19 is relatively greater than that of the solenoid valve 26 set in an opened state, and so the flow rate of the water is low.

(17) is a hot water circulation channel that circulates water discharged from the jet bath pump (16) to and from the bathtub (14). In the circulation waterway (17), the Mfi waterway (17a) on the suction side of the jet bath pump (16) communicates with the bath Ill (14) at the connection part (18), and the circulation waterway (17b) on the discharge side communicates with the nozzle part. (19) communicates with the bathtub (14). (20) is an air intake port placed at the top of the bathtub (14), and the intake air is taken into the nozzle part (19) by its negative box and is ejected from this nozzle part (19) as bubbly water. The aerated water has a massage effect, a cleansing effect, a thermal effect, etc. on the human body. The jet bath pump (l6) outputs an instruction signal in response to the off operation.
on/off control.

(22) is a branch pipe that communicates with the circulation waterway (17b) on the discharge side of the whirlpool pump (l6), and is piped so that it can supply water to the washing machine (23). The branch pipe (22), like the circulation waterway (l7), is buried in the walls of the bathroom and laundry room. (24) is a control device that controls the water supply etc. supplied from the branch pipe (22) to the washing machine (23).
23) is disposed at or near the operation panel section (25). The control device (24) includes a microcomputer (not shown) and controls the jet bath pump (24) based on its control signals.
16) etc.

(26) is a solenoid valve that constitutes a part of the control device 1 (24), and is interposed in the branch pipe (22). (27) is a washing machine (
When the water supply start switch is operated, it generates an instruction signal to open the solenoid valve (26), and based on this instruction signal, the microcomputer starts the jet bath pump (23). 16) and the solenoid valve (2ε), the solenoid valve (26) opens and functions to supply water to the washing machine (23). (28 is a water level sensor placed in the washing machine (23), which generates an instruction signal to close the solenoid valve (26) when the water level reaches the upper limit, and based on this instruction signal, the solenoid valve (26) ) to stop the whirlpool pump (16) at the same time.As mentioned above, the control device (24) cooperates as shown by the chain line.
