DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-handle type hot and cold water mixing tap.

[0002]

2. Description of the Related Art Recently, a one-handle type hot / water mixer tap which opens and closes by sliding two ceramic disc valves in close contact with each other and slides a cylinder valve up and down has been widely used. For example, see Japanese Patent Publication No. 5-84334 and Japanese Utility Model Publication No. 64-3880.

[0003] An example of the former one-handle type hot and cold water mixing tap will be described. 6 and 7, reference numeral 50 denotes a fixed disk, and 51 denotes a movable disk, both of which are made of ceramic.

[0004] The movable disk 51 is a working disk 52.
The working disk 52 is actuated by an operating lever 54 having a sector gear 53.

The fixed disk 50, the movable disk 51, the operating disk 52, the operating lever 54, and the like are housed in a cartridge case 56 covered with a lid 55 to form one set.

On the bottom of the cartridge case 56,
There is an opening for hot water, hot water, and hot water. For example, a large-diameter ring packing 57 is fitted in the hot-water opening, and a small-diameter ring packing 58 is fitted in the water opening.

[0007] This one-piece cartridge cage
The plug 56 is made of a bronze cast plug body 5 standardized by JIS.
9, the cartridge case 61 is housed so as to be positioned by the knock pin 60, and the cartridge holder 61 is screwed to the stopper body 59 to press and fix the housed cartridge case 56.

The cartridge holder 61 is covered with a makeup cap 62, and a handle 63 for operating the operating lever 54 is connected to the makeup cap 62.

Here, a water outlet 64 communicating with the disc valves (50) and (51) is integrally formed in the plug main body 59, and the following hot water and water passages are integrally formed. It is configured. In addition, the integral in this case is formed at the same time when the bronze casting is cast. Therefore, the weight of the entire hot and cold water mixing tap is 1500 g.

That is, in FIG. 7, a hot water introducing portion 65 and a water introducing portion 66 are integrally formed so as to protrude to both sides below the plug main body 59 to form a plug base. A hot water introduction pipe 67 is screwed and suspended in the hot water introduction section 65, and a water introduction pipe 68 is screwed and suspended in the water introduction section 66.

The cartridge case 56 is shown in FIG.
As shown in (1), it is partitioned in the middle of the plug main body 59 and is supported by a case supporting portion 69 formed integrally. Reference numeral 72 denotes a mounting surface of the sink.

[0012]

The one-handle type hot and cold water mixing taps described above have the following problems expressed in recent voices demanding safety.

The spout 64 is formed integrally with the plug body 59, and the plug body 59 is provided with hot water or a water passage 7.
0 is formed, and if only hot water is continuously spouted from the one-handle type hot and cold water mixing tap, the tap body 5
9 is heated and the user may be burned.

For this reason, the plug body 59 is covered with a cover body, or the spout, hot water or water introduction channel is formed of a copper alloy seamless tube, and these are covered with a cover body in the shape of the plug body. It is also conceivable to adopt an external cover method (for example, see Japanese Utility Model Application Laid-Open No. 61-114171). However, if such an external cover method is adopted, the case supporting portion 69 has a cartridge cover. Since a cylindrical portion (near reference numeral 71 in FIG. 6) surrounding the negative electrode 58 is formed,
This cylindrical portion is further covered with a cover body, and as a result, the outer diameter of the entire mixing faucet becomes large.

[0015]
