[0008]
In addition, the temperature control valve discharges at the fully open position of the hot water because the temperature in the hot water supply pipe is low at the beginning of discharge. Thereafter, when the temperature in the hot water supply pipe rises, the water moves rapidly toward the fully open position. For this reason, it took time for the discharge temperature to reach the set temperature.
[0009]

Example 1
Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in the conventional shower discharge device are denoted by the same reference numerals.
[0026]
FIG. 1 is a block diagram of a shower discharge device of the present invention. One side of the water 1 of the primary pipe is connected directly to the temperature control unit 16 via the hot water heater 2. The temperature adjusting valve 17 of the temperature adjusting unit 16 is driven by the temperature adjusting motor 4 which is a driving means. The temperature detection unit 5 detects the temperature of the hot water and drives the temperature adjustment motor 4 to discharge the shower from the discharge unit 20 at the set temperature.

After the temperature of the hot water reaches the set temperature, the main path on-off valve 19 is opened to start discharging the shower. . Thereafter, the drain valve 18 is closed. According to such an operation, when the hot water supply pipe 7 is long or in the winter, cold water in the hot water supply pipe 7 is discharged from the on-off valve 18 for drainage, so that no cold water is applied to the body.
[0028]
FIG. 2 is a structural diagram of the temperature adjusting unit of the shower discharge device of the present invention. Hot water from the hot water inlet 9 and water from the water inlet 10 are mixed by the temperature control valve 17 and discharged. The temperature of the discharged hot water is controlled by the temperature detector 5. When the set temperature and the tapping temperature are compared, and the set temperature is higher than the tapping temperature, the temperature adjustment motor 4 is driven to rotate and the temperature control valve 17 is driven to the right in the figure to increase the amount of hot water and raise the tapping temperature to approach the set temperature.

When the rotating shaft 11 rotates, the magnet 13 also rotates, and when the magnet 13 approaches the position where the Hall element 15 is attached, the Hall element 15 outputs a signal to detect the position of the temperature control valve 17.
[0032]
FIG. 3 is a plan view of the circular plate 14 as viewed from the temperature control motor 4 side. A Hall element 15 is attached to the circular plate 14. 15-1 is a water side limit detection unit that detects the water side limit position of the temperature control valve, and 15-2 is a hot water side limit detection unit that detects the hot water side limit position. An intermediate position detection unit 26 is provided at a substantially intermediate position between the water side limit detection unit 15-1 and the hot water side limit detection unit 15-2. At the intermediate position, the temperature of the hot water is generally well set at 60 ° C. The tapping temperature is set to 35 to 45 ° C.
