Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, a mixing valve unit 13 adjusts the mixing ratio of hot water and water sent from a hot water flow path 10 and a water flow path 11 by operating a hot water temperature adjustment handle 12.
A disk-shaped valve made of three stacked ceramics is provided downstream of the mixing valve section 13. The configuration of these valves and their surroundings is as follows from the upstream side: a plate-shaped first fixed valve body 14 having an opening;
, a first fixed sealing means 14' made of rubber for sealing the outer circumference of the first fixed valve body, a plate-shaped valve body 15 having an opening, and a second plate-shaped valve body having an opening. They are a fixed valve body 16 and a second fixed sealing means 16' made of rubber that also serves as a biasing means for sealing the flat surface of the second fixed valve body. The valve body 15 is provided between the first fixed valve body 14 and the second fixed valve body 16, and has a polished contact surface.By sliding and rotating in a watertight manner, the valve body 15 is connected to the first fixed valve body 14 and the second fixed valve body 16. from the valve body 14 to the second
The flow path to the fixed valve body 16 is switched. These valves 14, 15, and 16 constitute a switching valve 17. The valve body 15 is provided with a switching lever 18, and by sliding the switching lever 18 left and right, switching is performed on a plane substantially perpendicular to the inflow direction of the mixed water. And the switching valve 17
The mixed water is discharged to the side where the three valves 14, 15, and 16 are in communication between the flush side 20 and the shower side 22. During the sliding movement of the valve body 15 as the switching lever 18 slides, the sliding surfaces are only on both sides of the valve body 15 and on one side of the first fixed valve body 14 and the second fixed valve body 16 opposite thereto. Since the first fixed sealing means 14' and the second fixed sealing means 16' are always sealed in a fixed state, wear of these sealing means is prevented.
As shown in detail in FIG. 3, the first fixed valve body 1
4, the valve body 15, and the second fixed valve body 16 are provided with openings, and the valve body 15 rotates around the shaft 23 so that the surrounding area does not rub against the inside of the switching valve 17 and increase friction. is taken into consideration. and these 3
The valves 14, 15, 16 are held down by a fixture 24 provided on the upstream side, and the second fixed valve body 1
Second fixed sealing means 1 for sealing the flat surface of 6
6' also serves as a biasing means, and between the fixture 24, the first fixed valve body 14, the valve operating body 15, and the second fixed valve body 16
The parts are forced and held down in a planar direction, thereby streamlining the number of parts. Fig. 3 Three ceramic valves 14, 1
The positions of holes 5 and 16 are shown in Figure 4.
8 and the positional relationship between the holes in the ceramic valve bodies 14 and 15. When the switching lever 18 is in the center (Fig. 4b), the hole positions of the valve body 14 and the valve body 15 are aligned, and the opening 19 of the valve body 16 on the flush side is in communication, and the mixed water is supplied from the flush side 20. Exhale. When the switching lever 18 is slid to the left (FIG. 4a), the portion where the holes of the valve body 14 and the valve body 15 coincide is the shower side opening 21 of the valve body 16, and the mixed water is discharged from the shower 22. In addition, the switching lever 18
When the valve body 14 is slid to the right (Fig. 4c), the valve body 14
The holes (openings) of the valve body 15 and the hole (opening) of the valve body 15 do not match, and the mixed water is configured to stop discharging hot water. Note that the valve body 16 supports the valve body 15 and at the same time prevents water from leaking to the surrounding area.

With the above configuration, the mixed water adjusted to a desired temperature in the mixing valve section 13 is transferred to the switching lever 1 of the switching valve 17.
With a simple slide operation of the 8, you can not only switch to the flush 20 and shower 22 modes, but also stop the hot water supply with a single lever operation.

In addition, since the switching valve 17 is constructed from three ceramic discs, it has excellent durability and reliability, and is easy to operate.
Even the elderly and children can easily handle it. and,
If the switching lever 18 is placed in the center, hot water will be discharged, and if it is slid to the left, the hot water will be discharged.If the switching lever 18 is placed in the center, hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged.If the switching lever 18 is placed in the center, the hot water will be discharged. If you slide it to the right, the hot water will stop dispensing, quickly avoiding burns from boiling water, and allowing for smoother operation than when the stop position is in the center.

In addition, each of the three ceramic valve bodies has three or more holes in order to increase the opening area, thereby minimizing the increase in pressure loss during water flow.
It is possible to obtain a sufficient amount of hot water.

Effects of the Invention As described above, the hot water/cold water mixing faucet of the present invention provides the following effects.

(1) Switching between shower and flash mode and stopping hot water tap can be done by sliding a single lever.
When water with a mixed temperature is dispensed due to sudden changes in water pressure, etc., it is possible to quickly slide the lever and stop the dispensing of hot water instantly, greatly improving operability.

(2) Rather than twisting a conventional knob, the lever is configured to slide lightly, making it easy for even the elderly and children to operate.

(3) The relationship between each valve body and the sealing means is such that the first fixed valve body, the first fixed sealing means that seals the outer circumference of this first fixed valve body, the second fixed valve body, and this second fixed valve body.
The second fixed seal means seals the flat surface of the fixed valve body, and is sealed in a fixed state and has no sliding parts, making it highly durable and reliable.

(4) The second fixed seal means that seals the plan view of the second fixed valve body also serves as a biasing means, and the second fixed seal means seals the first fixed valve body, the second fixed valve body, and the valve operating body in a plane between the fixture and the fixing device. Since it is biased and pressed in the direction, it serves as both a sealing means and a biasing means, and the parts can be rationalized.

(5) By sliding the switching lever, you can switch the hot water supply, adjust the flow rate, and shut off the water.The water stop position is located at the right or left end of the switching lever, so it can be used at the neutral point in an emergency. Water can be stopped quickly and reliably.
