Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet replacement method for replacing a thermo type hot and cold water mixing faucet with a handrail type faucet, and a thermo type hot and cold water mixing faucet provided with a faucet body having an outer diameter of 34 mm, for example. It is about and.

[0002]

2. Description of the Related Art For example, at a lower part of a wall located in a bathroom washing room, a switch cock is switched to switch to a discharge pipe connection port or a shower hose connection port to supply water, hot water, or mixed water to the discharge pipe or shower hose. The thermo-type hot and cold water mixing faucet is installed horizontally. This faucet
A hot water supply temperature is adjusted by incorporating a temperature adjusting means in a tubular faucet body. That is, the temperature adjusting means is provided with a mixing passage communicating with the water supply side passage and the hot water supply side passage through the thermo valve body, and the mixed water temperature-controlled by the temperature adjusting means is directed in the axial direction of the faucet body. The water is supplied to the water discharge pipe connection port or the shower hose connection port from the annular passage extending along the valve passage, or the supply of the mixed water is stopped.

As the valve mechanism, a movable disk and a fixed disk that rotate together with the switching handle shaft in conjunction with the rotating operation of the switching handle are used. The two disks are arranged in the faucet body so as to be coaxial with the axis of the faucet body.

[0004]

By the way, both the movable disk and the fixed disk are expensive because they are made of ceramic. Further, the movable disk is rotated by the rotating operation of the switching handle, and the mixed water can be supplied from the annular passage by aligning the movable disk and the elongated hole provided in the fixed disk. Both disks had to be large in diameter because they were formed inside the disk. Therefore, the outer diameter of the faucet body is, for example, 46 mm, and the outer diameter cannot be further shortened, which has been an obstacle in making the thermo-type hot and cold water faucet compact.

On the other hand, a handrail is installed not only on the bathtub side but also on the wall on the side of the washroom for the purpose of assisting the operation in the bathroom. There was a case where the body was hit on the handrail.

Therefore, it is conceivable that the tubular faucet body is formed straight in a lateral direction to be used as a handrail, but the outer diameter of the faucet body is limited as long as both the disks are used as a valve mechanism. It is difficult to set the handrail to be installed in the bathroom to, for example, 34 mm that conforms to the standard.

The present invention is a faucet replacement method for replacing a thermo type hot and cold water mixing faucet with a handrail type faucet, for example, 34 mm.
An object of the present invention is to provide a compact and inexpensive thermo-type hot and cold water mixing faucet having a faucet body having an outer diameter of.

On the other hand, the temperature control unit 5 comprises a thermoelement 25 containing a thermowax and a piston 26. When the thermoelement 25 senses the temperature of the mixed water, the thermowax expands and pushes out the piston 26. By changing the position of the thermo valve main body 32, the gap between the water supply side passage 27 and the hot water supply side passage 28 is adjusted, and the temperature of the mixed water can be arbitrarily set by the temperature control handle 3. it can.

The automatic temperature adjusting operation of the temperature adjusting unit 5 is as follows. When the temperature control handle 3 is rotated around the axis A of the faucet body 1 and set to a predetermined temperature, the hot water and water are mixed in the hot and cold water mixing chamber S, and the mixed water at the predetermined temperature flows to the water discharge pipe or the shower hose. .

When the temperature of the mixed water rises above a predetermined temperature, the thermoelement 25 senses the temperature and the thermowax in the thermoelement 25 expands to move the thermoelement 25 to the temperature control handle 3 side. Then, the thermo valve body 32 narrows the hot water supply side passage 28 and widens the water supply side passage 27. As a result, the temperature of the mixed water is lowered and the temperature can be adjusted to a predetermined temperature. On the other hand, when the temperature of the mixed water falls below a predetermined temperature, the thermoelement 25 senses the temperature and the thermowax in the thermoelement 25 contracts to move the thermoelement 25 to the side of the switching handle 2 and the thermovalve body. 32 expands the hot water supply side passage 28 and narrows the water supply side passage 27. As a result, the temperature of the mixed water rises and can be adjusted to a predetermined temperature.

The thermoelement 25 is fixedly installed in the outer case 40 of the temperature control unit 5.

Reference numeral 41 connects the faucet body 1 and a tubular temperature control display ring body 42 having the same diameter as the faucet body 1, and
