Abstract

PROBLEM TO BE SOLVED: To prevent a scald by tightly fitting and inserting an inner cylinder formed of a heat resistant synthetic resin material to the inside of a main body outer cylinder formed of a continuous casting pipe, arranging a switching handle for supplying/ stopping mixed water and a switching unit on the right side of the main body outer cylinder, arranging a mixed water temperature regulating handle and a temperature regulating unit on the left side thereof, and mixing hot water with water on the downstream side of the temperature regulating unit. SOLUTION: After a right side switching handle 4 is operated so as to select changing over to an ejection opening or a shower ejection opening and supplying/stopping, temperature of mixed water is set by operating a temperature regulating handle 5. Hereby, this hot water/water combination tap can have extremely excellent operational performance, and hot water is mixed with water on the just downstream side of a temperature regulating unit 10 in an inner cylinder 6, therefore, even though temperature is set to a high temperature, a main body outer cylinder 1 may not be heated so much, and the fear of a scald is eliminated. Also, the main body outer cylinder 1 is formed into a continuous casting product, thereby a yield rate is improved, and products having equal qualities can be manufactured at a low cost.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention belongs to the technical field of a hot and cold water mixing tap capable of supplying water or temperature-controlled mixed water.

[0002]

The body case of a hot and cold water mixing tap is conventionally integrally formed by casting, and
A thermo valve, a switching valve, etc. were charged, and a hot and cold water mixing chamber for mixing hot and cold water was provided.

The body case made of such a cast product is
In addition to being expensive, it is difficult to obtain a homogeneous product, and the yield is poor.

Further, the portion of the hot and cold water mixing chamber, which is in direct contact with hot and cold water, is likely to reach a high temperature and may be hot to the touch and may cause burns.

The present invention has been made in view of such circumstances,
It is intended to provide a hot and cold water mixing tap that is inexpensive and does not cause burns.

[0006]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, there is a hot and cold water mixing tap connected to the hot water supply path and the water supply path and configured to supply water or temperature-controlled mixed water, and at least connected to the hot water supply path and the water supply path, respectively. A main body outer cylinder having a connection port and a discharge port for water and mixed water is made of a continuous casting pipe formed by a continuous casting method, and at least the water or the mixed water is supplied to the right end of the main body outer cylinder when viewed from the front. A switching handle for stopping is provided, while a temperature adjusting handle for adjusting the temperature of the mixed water is provided at the left end, and a heat-resistant synthetic resin material is provided in the outer cylinder of the main body. An inner cylinder is tightly fitted and a switching unit connected to the switching handle and a temperature control unit connected to the temperature control handle are provided in the inner cylinder, and a temperature control unit is provided downstream of the temperature control unit. Hot water It is characterized by mixed.

By forming the outer cylinder of the main body with a continuous casting tube, a product with good yield and low cost can be obtained, and since hot and cold water is mixed in the inner cylinder made of a synthetic resin material, the main body is easily touched directly by hand. The outer cylinder does not get hot and there is no risk of burns.

BEST MODE FOR CARRYING OUT THE INVENTION The hot and cold water mixing valve of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view of a hot and cold water mixing plug, wherein reference numeral 1 is a main body outer cylinder made of a continuous casting pipe formed by a continuous casting method, 2 is a hot water intake socket (connection port) fitted in the main body outer cylinder, 3 is a water intake socket (connection port)
The hot water intake socket 2 and the water intake socket 3 are connected to the hot water supply passage and the water supply passage through a crank-shaped connecting pipe (not shown).

Reference numeral 4 is a switching handle provided at the right end of the main body outer cylinder 1, 5 is a temperature control handle provided at the left end thereof, and 6 is tightly fitted inside the main body outer cylinder 1 via O-rings 7 and 8. An inner cylinder made of a heat-resistant synthetic resin material, 9 is a switching unit connected to the switching handle 4, and 10 is a temperature control unit connected to the temperature control handle 5.

A ceramic disc is housed inside the switching unit 9 described above, and the ceramic disc is rotated by the rotating operation of the switching handle 4. It is possible to control the supply and stop of water or mixed water to the discharge port provided or the shower discharge port provided immediately after the discharge port.

Further, the temperature control unit 10 comprises a thermoelement 11 having a thermowax and a piston 12, and when the thermoelement 11 senses the temperature of the mixed water, the thermowax expands and pushes out the piston 12. By changing the position of the thermo valve 6, the gap between the water supply side passage 13 and the hot water supply side passage 14 is adjusted, and the temperature of the mixed water can be arbitrarily set by the temperature control handle 5.

More specifically, the temperature control handle 5 is rotatably fitted to the end of a ring body 51 screwed to the end of the main body outer cylinder 1, and is provided inside the ring body 51. The base portion of the slide guide 17 screwed on the inner peripheral surface of the temperature control upper body 16 is spline-coupled. By rotating the temperature control handle 5, the slide guide 17 is moved back and forth to move the piston. The setting position of the valve main body 19 is variably adjusted via 12, and as described above, the gap between the water supply side passage 13 and the hot water supply side passage 14 is adjusted.

In the hot and cold water mixing valve constructed as described above, first, the switching handle 4 on the right side is operated to switch to the discharge port or the shower discharge port and supply / stop is selected. It suffices to set the temperature of the mixed water by operation, and the operability is extremely good, and since the mixing of the hot water is performed immediately downstream of the temperature control unit 10 in the inner cylinder 6, even if the temperature is set to a high temperature. Also, since the outer cylinder 1 of the main body does not become so hot, there is no risk of burns. Further, since the main body outer cylinder 1 is a continuously cast product, the yield is improved, and a homogeneous product can be obtained at low cost.

[0014]

As described above, according to the hot and cold water mixing valve of the present invention, the outside of the main body having at least the hot water supply passage and the connection ports respectively connected to the water supply passage and the discharge ports of the water and the mixed water. The cylinder is formed by a continuous casting pipe, and a switching handle is provided at the right end and a temperature control handle at the left end of the main body outer cylinder when viewed from the front. Inside the main body outer cylinder, a heat-resistant synthetic resin material is used. A cylinder is tightly fitted and a switching unit connected to the switching handle and a temperature control unit connected to the temperature control handle are provided in the inner cylinder, and hot and cold water is provided downstream of the temperature control unit. Since it is mixed with water, the operability is extremely good and it is easy to use.Because the hot and cold water is mixed in the inner cylinder, the outer cylinder of the main body will not become so hot even if the temperature is set to a high temperature. There is no fear of. Further, since the outer cylinder of the main body is a continuously cast product, it is possible to improve the yield and provide a uniform product at a low cost.
