Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a mixed water powder that can automatically adjust the temperature of hot water using a temperature-sensing function in sanitary equipment.

Conventionally, a hot water/cold water mixer faucet of a type in which a temperature-sensitive medium is used to sense the temperature difference between hot water and water and a valve body is actuated by the sensing operation is shown in FIG. (Figure).

To explain with reference to Fig. 1 Km above, the pulp main body 40 has a trunk 41 leading to the shower head and a tap s41' leading to the faucet 42 on the upper and lower sides (in the figure), among which 1! One threaded opening 44.
A valve chamber 4jS and a separate hot water outlet 46° and water outlet 47 are provided concentrically, and the valve cylinder 4 is connected to the valve chamber 4j via @4B to the valve chamber 4jS.
9 is installed inside so that it can move forward and backward freely, and an interior δl for pressure regulation with one end of the temperature-sensitive medium bO interposed in the skeleton valve cylinder 49 is installed inside with ammunition,
At one end of the valve chamber 45, a valve shaft body 56 having a chamber 52 for enclosing the temperature-sensitive medium 50, a body portion 64 having a number of through holes 58, and a shaft portion b5 is reciprocated in the axial direction. A valve body 57 is provided inside the valve shaft b6 and adjusts the flow rate of hot water.
By opening either of the frame parts 41, 41, the hot water that has reached the mixing chamber 48 in advance or hot water mixed with water can be supplied to the faucet 42 or the shower head. .

In the above-mentioned pulp body, since the hot water and water are stopped in the mixing chamber on the secondary pressure side, the fluid on the side that overcomes the pressure, especially the water side or the hot water side, flows backwards and the hot water flows back. There were inconveniences such as a drop in temperature on the side, which caused the pilot flame to naturally extinguish, leading to a gas leak.

In addition, since the sensitivity mechanism that controls the temperature and the water shutoff function that cuts off the fluid are integrated, the overall structure of the mixer faucet becomes oversized and is difficult to handle during production processes such as casting, processing, and assembly, as well as packaging and transportation. Not only does this increase the cost of transportation, but also there is a lack of safety due to incorrect operation of the handle during use.

This invention solves the above problems, reduces heat consumption by separately shutting off hot water and water on the primary pressure side, simplifies the mechanism, increases productivity, and improves safety through correct handle operation. The basic structure of the present invention is to form a pulp body that is connected to a hot water supply source by providing a hot water passage and a water passage on one side in the axial direction, and An eccentric gripping socket is provided, a fluid circulation chamber and a communication chamber are arranged concentrically in the axial direction along the gripping socket, and a pair of facing valve bodies and a temperature-sensitive medium are placed in this gripping socket. Inserting and connecting the internal valve cylinder, elastically engaging the temperature-sensitive medium with an actuator of a temperature control mechanism connected to the valve cylinder mouth end, and a spring on the chest of the nut corresponding to the actuator; The ceramic springs of both valve bodies of the pair are elastically balanced, and both valve bodies are actuated by temperature sensing of a temperature-sensitive medium so that the flow rate Yt of hot water and water can be adjusted appropriately. .
