Is a water supply pipe connected so as to supply tap water to the valve box 40 from the water stopcock 47. Reference numeral 48 is a water receiving box provided to receive the slack of the hose 12 and prevent the water adhering to the hose 12 from scattering.

Reference numeral 50 denotes an operation panel set on the counter 2. The operation panel 50 has a waterproof film having various functions printed thereon as shown in FIG. A switch or the like that performs each function is provided. That is, 51 is an operation switch including an up switch 52 with "up" displayed and a down switch 53 with "down" displayed, 54 is a water stop switch, 55 is a lamp that lights up when water is discharged, Reference numeral 56 is a water discharge flow rate adjustment switch with indications of "small" and "large", 57 is a flow rate display lamp formed by arranging a plurality of light emitting diodes to display the discharge flow rate, 58 is a water / hot water changeover switch, 59 , 60 is its water display lamp and hot water display lamp, 61 is a switch for raising the temperature of the hot water, 62 is a switch for lowering the temperature of the hot water, 63

Connected through. Reference numeral 66 is a power cord of the controller box 41, and 67 is a battery provided in the controller box 41 for backup in case of power failure.

A controller composed of a microcomputer is provided in the controller box 41, and the microcomputer receives an instruction from the operation panel 50 to open and close the water shutoff valve in the valve box 40 to operate the water discharger 13. The valve box 4 controls the discharge of hot and cold water.
The electric mixing valve in 0 is operated to control the mixing ratio and flow rate of the hot water to adjust the hot water temperature and flow rate discharged from the water discharger 13 according to the command, and the temperature and flow rate are displayed on the display 63 and the flow rate display lamp 57, respectively. Display it.

The drive controller for controlling the rotation of the motor 24 is, as shown in FIG. 8, the rising switch 52, the falling switch 53, and the rising limit detector 70.
A descending limit detector 71 is connected and a timer function unit is provided to issue a rotation command to the motor 24 to raise or lower the slider 10.

FIG. 9 shows a flowchart of the drive controller when the raising switch 52 is operated. Further, FIG. 10 shows a flowchart of the drive controller when the lowering switch 53 is operated. As shown in FIG. 9, when the ascending switch 52 is operated in step a, it is determined in step b whether or not the ascending limit detector 70 is on. When it is on, it is determined that the slider 10 is already at the upper limit, Only when the motor is stationary at the rising limit and is off, a rotation command signal for rising is output to the motor 24 as shown in step c. At the same time, in step d, a start command is issued to the timer function section and the continuous rotation time of the motor 24 is counted.

When the rising limit detector 70 is turned on as shown in steps e and f, or the rising switch 5
When 2 is turned off, the motor 24 is stopped as shown in step h. Therefore, the slider 10 can be stopped at an arbitrary height by turning off the raising switch 52. Further, when the rising limit detector 70 is not turned on, the rising switch 52 is not turned off, and the count number of the timer function unit started in step d is not up, the motor 24 is continuously rotated. Then, when the time (for example, 30 seconds) preset in the timer function unit has passed (time-up), the raising switch 5
In response to the time-up signal, a drive stop signal is output to the motor 24 to stop the motor 24 regardless of the continuous operation of 2.
At the same time, in step i, the counting of the timer function unit is stopped. Then, unless the raising switch 52 is turned off in step j, the motor and the timer function section are held in a stopped state, and if the switch 52 is turned off, the count of the timer function section is reset to zero as shown in step k, and the step a is executed. Return.

On the other hand, when the lowering switch 53 is operated, the lowering limit detector 7 in this case is the same as when the raising switch 52 is operated as shown in steps a to d of FIG.
Unless 1 is turned on, the motor is driven to start the timer function unit, the motor is continuously rotated in steps e to g, and when the timer function unit times out a predetermined time, the lowering switch 53 is not turned off. Also, the motor is stopped as shown in step h.

FIG. 11 is a timing chart showing the operation of this drive controller. The drawing shows the case where the raising switch 52 is turned on when the slider 10 is at the lower limit and turned off during the ascent, and when the slider 10 is at the intermediate height, the raising switch 52 is turned on and reaches the upper limit. It shows the case of stopping. Further, indicates a case where the raising switch 52 is continuously turned on and the timer function unit has timed up for a predetermined time. In this case, regardless of the continuous operation of the raising switch 52, as shown in step h above. Then, the motor drive signal is stopped and the motor is stopped. Moreover, the case where the motor is stopped by operating the lowering switch 53 and operating the lowering limit detector 71 is also shown.

In the above embodiment, the device for pulling out the flexible hose 12 from the slider 10 has been described, but the present invention is not limited to such a water spout lifting device. For example, in the water spout lifting device shown in FIG. 12, a holder 82 capable of detachably supporting the water spout 81 is provided at the upper end of a slider 89, and a water supply hose 83 for the water spout 81 is inserted into the slider 89. The water is supplied from a separate water supply source (not shown) such as a hot and cold water mixing tap. In this case also slider 8
The present invention can be applied to raising and lowering 9. In the example shown in FIG. 13, the slider 84 itself is a water supply pipe,
The lower end of the slider 84 is connected to a water supply source via a hose (not shown), and the upper end of the slider 84 has a water discharger 85.
A holder 86 for receiving the water is provided, and a hose 88 of the water discharger 85 is connected to a water supply connection port 87 that is provided on a side of a mounting base of the holder 86. In addition, as shown in FIG. 14, a water discharger 91 is fixed to the upper end of a slider 90 which also serves as a water supply pipe as in the above, and the water discharger as illustrated in these FIGS. The present invention can also be applied to a device for making the above.
