離脱し、混合湯はカラン２９がら吐出することになる。In FIG. 1, a mixing valve 20 consisting of a hot water valve 18 and a water valve 19 provided in a hot water flow path 16 and a water flow path 17, respectively, and the hot water valve 18 and water valve 19 are each independently driven electrically. A mixing valve driving device 23 consisting of a hot water valve driving device 21 and a water valve driving device 22, a temperature detector 24 for detecting the mixed water temperature downstream of the mixing valve 2o, and a setting device 25 for setting a desired temperature. The signal is compared with the signal from the temperature detector 24, and based on the amount of deviation, a signal is sent to the mixing valve driving device 23 to adjust the valve openings of the hot water valve 18 and the water valve 19 to make the mixed water temperature equal to the set temperature. Is there a system to control it? 8 vessels 26
has been established. The temperature-controlled mixed hot water is discharged from the shower head 28 or the shower head 29 through the switching valve 27, and the switching valve 27 has a structure in which the shower-side valve body 31 and the shower head are connected to the opening facing the shower outlet path 3o. side valve seat 32,
A flush side valve body 34 and a flush side valve seat 35 are provided facing each other at the opening facing the flush flow path 33, and the shower side valve body 3
1 and the flush-side valve body 34 are fixed to the same shaft 36, and the valve opening degree changes in inverse proportion to each other by pushing the switching knob 37, thereby switching the discharge destination. A temperature safety device 38 is provided in front of the switching valve 27, and its structure includes a wax thermostat body 39 that is sensitive to the temperature of the mixed water, and a thermosensitive wax sealed in the wax thermostat body 39 that expands due to thermal expansion. There is a rod 40, and a rod support 42 is biased by a rod bias spring 41 at the tip of the rod 4°.
It is held in When the mixed water temperature exceeds a predetermined temperature, the wax thermometer body 39 (7)'7x expands and pushes out the rod 4o, but since the rod 4° is held by the rod support 42, the rod 40 does not extend. At the same time, the wax thermostat main body 39 moves. The wax thermo body 3
The safety lever 43 fixed to the switch valve 9 moves at the same time, and the safety lever 43 acts on the shower side valve body 31 of the switching valve 27, bringing the shower side valve body 31 into contact with the shower side valve seat 32. The valve body 33 is removed from the valve seat 34 on the collar side, and the mixed hot water is discharged from the collar 29.

合湯は吐出しており、動作したことを認識できる。As described above, in this embodiment, as soon as high-temperature mixed hot water is about to be discharged due to some reason during shower discharge, the temperature safety device 38 is activated and automatically switches to flush discharge, thereby avoiding the risk of being exposed to high-temperature water. It is something to do. In addition, the above effect is limited to the shower discharge, so Karan 29
It is possible to discharge the full temperature of the boiler, and even after the safety device 38 is activated, the mixed hot water is discharged from the two shells instead of stopping the hot water supply, and it is possible to recognize that it has worked.
