Abstract

PURPOSE:To simply and lightly switch a delivery port and regulate a delivery amount, by a method wherein a switching lever, directly coupled to one of the three ceramic discs of a switching valve is slid in a direction extending about at right angles with the incoming direction of the mixed water. CONSTITUTION:A switching valve 17 formed with three laminated ceramic valve bodies 14,1 5, and 16 is situated down a line from a mixing valve part 13, the upper and lower valve bodies 14 and 16 of the switching valve 17 are secured, and the middle valve body 15 is directly coupled to a switching lever 18. The switching lever 18 can be slid on a plane extending about at right angles with the incoming direction of mixed water. With the switching lever 18 situated at the central part, switched to the left, and to the right, a faucet is forced into a discharge-through-faucet state, a shower state, and a state to stop the feed of hot water, respectively.

Description

[Detailed description of the invention] Industrial application field original F! A relates to a replacement hot/cold mixer faucet for showers that mixes hot water and water to obtain the appropriate temperature.

2. Description of the Related Art Conventionally, this type of mixing faucet for hot water and cold water has been shown in FIGS. 4 and 5. (For example, Utility Model No. 53-105138
(No. Publication) In FIGS. 4 and 5, a knob 3 that adjusts the mixing ratio of hot water flowing in from the hot water conduit 1 and the water conduit 2, an opening/closing knob 4 that opens and closes the flow path, and a plurality of mixed hot water It is composed of a switching handle 5 and a main body 6 for switching to a desired outlet among the outlets, and FIG. 6 shows a sectional view of the switching valve section operated by the switching handle 5.

The switching valves 7 connected by each rotation of the switching handle 5 are thrust-interlocked, and one seat surface (8 or 9
) is configured to separate from the other sheet surface (9 or 8) and open when it is closed.

Problems to be Solved by the Invention However, in the above configuration, the switching handle 5 is changed by rotating, so if hot water comes out due to fluctuations in water pressure while using the shower, the switching handle or opening/closing handle must be twisted. The (rotating) means takes time to operate and may be particularly burdensome for elderly people and children.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hot water/cold water mixing faucet that allows easy and convenient replacement of the discharge port and adjustment of the discharge amount, and has excellent durability and reliability.

Means for Solving the Problems In order to solve the above problems, the hot water mixer faucet of the present invention has the following features:
A mixing valve that adjusts the mixing ratio of hot water and water, and three ceramic discs stacked on top of each other downstream of the mixing valve rotate and slide to adjust and stop the amount of mixed water being discharged. A switching valve is provided for switching between the flush side and the shower side, and a switching lever directly connected to the central ceramic disc of the three ceramic discs of the switching valve is switched by sliding a plane substantially perpendicular to the inflow direction of the mixed water, or The discharge amount can be adjusted and stopped.

According to the above-described structure, the present invention allows mixed water adjusted to a desired temperature by a mixing valve to be changed to a discharge destination and to a discharge amount by a simple sliding operation of a switching lever of a switching valve provided downstream of the mixing valve. Adjustments can also be made with a single touch.

Example Embodiments of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 and 2, the hot water and water sent from the hot water flow path 10 and the water flow path 11 are operated by operating the hot water temperature adjustment handle 12,
a mixing valve section 13 that adjusts the mixing ratio; and the mixing valve section 13
Three ceramic valve bodies 14, 15 stacked downstream of
．． 16, the upper and lower two valve bodies 14 and 16 are fixed, and a switching lever 18 is directly connected to the central valve bodies 1 and 5, and when the lever 18 is operated, , the valve body 15 rotates, and the locations (openings) where the holes provided in the valve bodies 14, 15, and 16 coincide change, and the discharge state changes. FIG. 3 shows the positions of the holes in the three ceramic valves 14, 15, 16, and FIG. 4 shows the positional relationship between the position of the switching lever 18 and the holes in the ceramic valve bodies 14, 15.

When the switching lever 18 is in the center (Fig. 4(b)), the hole positions of the valve body 14 and the valve body 15 match, and the part that communicates is the flush side opening 19 of the valve body 16, and the mixed water flows through the flush side opening 19 of the valve body 16. Discharge from 20. When you slide the switching lever 18 to the left (
In FIG. 4 (JLI), the part 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. Furthermore, when the switching lever 18 is slid to the right (Fig. 4 (C)), the holes (openings) of the valve body 14 and the valve body 15 do not match, and the mixed water is configured to stop dispensing. There is. Note that the valve body 16 is similar to the valve body 15.
At the same time, it prevents water from leaking into the surrounding area.

With the above configuration, by a simple sliding operation of the switching lever 18 of the switching valve 17, the mixed water adjusted to the desired temperature in the mixing valve part 13 can be switched to the flusher 20 and the shower 22, and the hot water can also be stopped with a single lever operation. This is possible.

In addition, since the switching valve 17 is constructed of three ceramic discs, it has excellent durability and reliability, and is easy to operate, allowing even the elderly and children to handle it easily. If the switching lever 18 is placed in the center, hot water will be discharged, if it is slid to the left, the hot water will be discharged, and if it is slid to the right, the hot water will be stopped.
Therefore, when the mixed water temperature becomes high due to fluctuations in water pressure, etc., simply slide the changeover lever 18 to the right to stop the hot water supply, quickly avoiding burns caused by boiling water, and making it easier than when the stop position is in the center. , which can be operated smoothly.

In addition, each of the three ceramic valve bodies has three or more holes in order to increase the opening area, which minimizes the increase in pressure loss when water flows through, making it possible to obtain a sufficient amount of hot water. It is.

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

(1) It is possible to switch between shower and flush mode and stop hot water dispensing with a single lever slide operation, so when hot mixed water is dispensed due to sudden changes in water pressure, etc., you can quickly slide the lever to stop dispensing hot water. This can be done 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) Since the switching valve doubles as an on-off valve, costs are reduced and assembly is simplified.

(4) The switching valve is composed of three ceramic valve bodies, so it has excellent durability and reliability.
