TECHNICAL FIELD The present invention relates to improvements in ceramic plate valves and operating means before hot / cold water mixing in sanitary appliances.

Background Art Conventionally known valve mechanisms using a pair of ceramic valves incorporated in a valve chamber of a mixed faucet are those shown in FIGS. 1 and 6 of JP-A-56-37179. And FIG. 8).

7 and 8, the movable plate valve 40 has a closed bore-shaped mixing chamber 41 opened downward and is polymerized to the fixed plate valve 42. The inlet 43 and the cold water inlet 44 correspond to the opening and closing material so that the outlet 45 is always in communication. When the lever 46 is in the solid line position, the hot water inlet 43 and the cold water inlet 44 are When the lever 46 is pushed downward to the horizontal position of the chain line, the same amount of hot water and cold water are discharged, and when the lever 46 is rotated horizontally and leftward, hot water is discharged and rotated to the right direction. When the cold water is discharged, when the water is discharged, the lever 46 is returned to the center to return it to an upward position, so that the automatic valve 40 connected to the lever 46 through the valve rod 47 is fixed plate valve. Guide portion engaged with guide groove 48 formed in 42 Through 49, the forward and backward movements are performed to discharge and cool the hot and cold water.

In the above, the discharge and index of hot and cold water are performed by the operation of the lever up and down, and the hot and cold water are separately or by only the hot water and the cold water are discharged by the left and right operation of the lever. In the case of a handicapped person with a physical disability, such a defect is very difficult to use and easy to misoperate. In addition, since the flow rate of the cold water is drastically reduced when the hot water inlet is completely opened, there is an inconvenience that the temperature of the hot water must be adjusted again each time.

Furthermore, since the movable plate valve is subjected to rotational movement to perform the reciprocating motion forward and backward, the fixing mechanism of the fixed plate valve and the valve rod becomes complicated, and the number of parts requires a complicated labor such as disassembly during assembly and failure. Manager productivity will be extremely bad.

The problem solved by the present invention is to supply the hot water and cold water separately and supply the mixed water, control the temperature and supply water, and the index only by simply rotating the movable plate valve for opening and closing the valve of the valve mechanism only in the horizontal direction of the lever. At the same time, by simplifying the linkage mechanism between the lever and the movable plate valve, it is easy to use, and there is almost no operational error and simplified maintenance.

The present invention has been made in order to solve the above problems, the technical means for forming a movable plate valve of a pair of fixed plate valves of the same plate shape by the molding of a ceramic, the movable plate valve is a wet contact surface (in the embodiment) It has a cold water guide that communicates with the cold water inlet of the fixed plate valve by switching the lever at one end, and has a hot water guide that communicates with the hot water inlet of the fixed plate valve by switching the lever. At the same time, there is provided a distribution groove which is in constant communication with the outlet of the fixed plate valve, and at the periphery of the upper surface of the movable plate valve, a plurality of gages are provided for the engaging piece and the locking hole engaged with the fixed plate valve. The cold water inlet and the outlet are both penetrated through the upper and lower sides of the fixed plate valve, and the fixed plate valve and the movable plate valve By the clam to be assembled to each other 's contact face constitutes a valve plate unit.

The main body before the mixing is to support the fixed plate valve through the seat plate inside, and to the valve chamber of the inner cylinder coupled with the seat plate in the upper direction, the boss engaged with the rotating material by the engaging piece and the locking hole, and through this boss The movable plate valve and the fixed plate valve are connected to each other by a wet contact surface via a movable plate valve, and a hand grill having a lever is mounted on the wave side formed in the boss through a piece. By simple operation, the proper supply of hot water and cold water, the supply of mixed water of appropriate temperature, and the temperature control are performed. By supplying a suitable amount of hot water and cold water and supplying a mixed temperature of a suitable temperature by a simple operation only in the horizontal direction of the lever, hot water and cold water can be selectively supplied and indexed according to the use of various waters.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the embodiment of the present invention, as shown in Figs. 1 to 3a and 3b, a pair of fixed plate valves 1 and a movable plate valve 2, which are formed of ceramics and formed into the same disc shape by molding, are provided. On the wet contact surface 3 of the fixed plate valve 1 (the opposing surface with the movable plate valve 2), the cold water guide 6 formed in the shape of a hole blocked by the movable plate valve 2 at one end and the lever 5 to be described later. It has a cold water inlet (4) in communication by the switching of, the other end of the hot water inlet (7) in communication with the switch of the lever 5 in the same way as the hot water guide (8) of the movable plate valve (2) At the same time, the movable plate valve 2 is continuous with the hot water guide 8 and the cold water guide 6 at the same time, and is always in communication with the outlet 9 of the fixed plate valve 1. (10), the locking pin 12 to be described later on the other surface of the distribution groove 10 (that is, the upper edge of the movable plate valve 2) The plurality general statement to the engaging system jigong 13 for. Further, the cold water inlet 4, the hot water inlet 7 and the outlet 9 are all penetrated through the upper and lower surfaces of the fixed plate valve (1) and the fixed plate valve (1) and the movable plate valve (2) The plate valve unit A is formed by combining the moving plate valve 2 toward the wet contact surface 3a. In addition, the main body B, before mixing, attaches the casing 15 to the screwed portion 14 of the upper portion, and at the same time, the inner cylinder 18 having the seat plate 16 and the valve chamber 17 is coupled to the care 15. The valve chamber 17 is built by fitting the mutually wet contact surfaces 3 and 3a with the fixed valve 2 and the movable valve 2 upward.

The deflection shaft 19 is integrally coupled to the boss 20 by embedding molding, and the boss 20 is a step surface 21 (21a) symmetrical with the inner cylinder 18 embedded in the casing 15. Corresponding to the sliding material in the direction of rotation through the horizontal hole 22 formed in the boss 20 and the deflection shaft 19, the spring 23 for stopping the boss 20 at the exponential position later While arranging the ball 24 and engaging the stopper 25 installed on the main surface of the boss 20 and the horizontal guide groove 26 opened in a semicircular arc in the horizontal direction. By this, the stopper 25 hits the end portion 27 in the left direction and becomes a hot water supply position for later stopping, and the stopper 25 collides with the end portion 27a in the right direction for stopping the position where it stops. Each is linked to be a water supply position.

The locking piece 12 protrudes a plurality of the bottom surface of the boss 20, the locking piece 12 is fitted to the locking hole 13 provided on the upper periphery of the movable plate valve 2 and the boss It is linked to the same rotation as (20).

The handle grille 28 is coupled to the wave side 19 via a piece 29, and protrudes the lever 5 in the horizontal circumferential direction above these handle grilles 28, and this lever 5 When the hot water and cold water are flush with each other in the same vertical line as the water discharge pipe 30, the lever 5 is moved horizontally to the left in the water discharge position at the water discharge position. In FIG. 6, the entire hot water is hot water via the hot water supply path 31 of FIG. 6, and at the same time, a portion of the distribution groove 10 and the corner portion 4a of the cold water inlet 4 are in communication with each other. In this case, when the flow groove 10 and the cold water inlet 4 are slightly communicated, for example, when the whole amount of hot water is supplied for a long time, the water in the water supply chamber 32 is sequentially overheated by OML to the heat conduction and mixed before The surface of the main body B is corresponded so that abnormal overheating can be prevented. In addition, when the lever 5 is moved between the still water position and the hot water supply position, the mixing ratio of the hot water and the cold water and the hot water temperature can be freely adjusted, and the lever 5 is halfway between the still water position and the water supply position. ), Respectively, so that the flow rate of the cold water can be freely adjusted, and the water supply chamber 32 is the water discharge chamber of FIG. 1 through the distribution groove 10 and the outlet 9 at the cold water inlet 4. In the case of (11), water is supplied to the water discharge pipe 30, and the hot water reaching the hot water supply chamber 33 is the same in the water inlet 7 through the distribution groove 10 and the outlet 9 through the water discharge chamber. It communicates with each other so that hot water may be supplied to the water discharge pipe 30 via (11).

Now, when the lever 5 in the exponential position is sequentially moved to the left in the position shown in FIG. 4A, the boss connected to the handle grill 28 integrated with the lever 5 via the waveshaft 19 As the 20 rotates in the same direction, the movable plate valve 2 associated with the boss 20, the engagement piece 12, and the engagement hole 13 is rotated in the same direction, so that the movable plate valve 2 The hot water guide 8 installed in the distribution groove 10 and the hot water inlet 7 of the fixed plate valve 1 communicate with each other and at the same time the cold water inlet 6 of the distribution groove 10 and the cold water inlet of the fixed plate valve 1. In connection with (4), supplying hot water and cold water almost equally, and if the lever 5 is displaced further to the left as it is in this positional relationship, the amount of hot water increases sequentially, and the amount of cold water approaches zero. The stopper 25 of 20 approaches the end 27 side in the horizontal guide groove 26 so that the stopper 25 The lever 5 is stopped at the collision place, and supplies the whole amount of hot water at this stopped position. In this supply hot water, the relationship between the distribution groove 10, the hot water inlet 7 and the cold water inlet 4 is in full communication with the hot water guide 8 and the hot water inlet 7 as shown in FIG. 5A, and the cold water guide 6 ) And the cold water inlet 4 are closed, but at this time, a part of the distribution groove 10 and the corner portion 4a of the cold water inlet 4 are in small communication with each other to cool the cold water in the water supply chamber 32 together with the hot water. Spills. Therefore, even if only hot water is continuously supplied, the water in the water supply chamber 32 is prevented from thermally expanding.

After the hot water supply is finished and the lever 5 is once returned to the index position, the lever 5 is moved to the right direction, whereby the supply water for cold water gradually increases to obtain the required water quantity. Subsequently, when the lever 5 is moved to the right, the stopper 25 of the boss 20 is approached and approached toward the end 27a in the horizontal guide groove 26 in the same manner, and the stopper 25 is approached to the end 27a. ), The lever 5 is stopped to the water supply position, and the entire amount of cold water is supplied from this water supply position.

At this time, the relationship between the distribution groove 10 and the cold water guide 6 increases the flow rate of the cold water sequentially in the middle of the lever 5 in the right direction. .

The present invention is configured as described above has the following advantages.

(1) It is concave in the shape of a hole in which the flow grooves having cold water guide and hot water guide are blocked on both sides of the wet plate of the movable plate valve, and when the lever is rotated horizontally from the exponent position to the left, the flow rate of the mixed water and the hot water By adjusting the temperature and supplying the whole amount of hot water and rotating the lever horizontally from the index position to the right side, the whole amount of cold water can be supplied.

(2) The locking plate and the locking piece are engaged with the movable plate valve and the boss, and at the same time, the wave side and the handle grille formed on the boss are integrally combined. As a result, usability is always maintained, and there is no danger of suddenly discharging hot water even if the lever is suddenly operated in either direction.

(3) The boss and the symmetrical stepped surface surrounding and supporting the boss are adapted to facilitate sliding, so that they can be strongly responded to the fluid pressure applied to the movable plate valve so that they are not affected. The rotation of the valve allows for smooth operation without pressure constraints.

(4) It is different from the conventional lever operating up, down, left, and right, and the necessary hot water, cold water, and mixed water can be obtained by simple handling of operating the lever horizontally in the horizontal direction, and it is improved in use.
