It is necessary to provide an auxiliary mechanism for various types of hot water control, such as eliminating mutual interference between the ratio adjustment and the flow rate adjustment and preventing a water hammer. However, in order to perform these hot and cold water controls, it is necessary to adopt, as a basic structure of the mixer tap, a structure that can easily attach those control mechanisms,
Known hot / water mixer taps lack this consideration, and as a result, tend to have a complicated structure, an increased number of parts, and an increased cost.

Rotation of the operating lever adjusts the mixing ratio of hot water and vertical operation of the operating lever adjusts the total amount of hot water flowing out of the hot water outlet, and stops the hot water at one operating end. More specifically, when the operating lever is rotated in a horizontal plane, the outer cylinder rotates accordingly, and the hot water and water inflow ports provided on the valve body have a required opening degree corresponding to the rotational position of the outer cylinder. Since it communicates with the through hole of the outer cylinder at a predetermined ratio, hot and cold water are mixed at a required mixing ratio according to the rotation angle of the operation lever. On the other hand, when the operation lever is operated in the vertical direction, the inner cylinder slides up and down in the outer cylinder accordingly,
Since the opening degree of the through hole provided in the outer cylinder is adjusted by the water control wall of the inner cylinder, the total amount of hot water flowing out of the hot water outlet is adjusted, and when the inner cylinder reaches the lower end, the outflow of hot water is stopped.

ンマーの防止をも容易に行うことができる。As is apparent from the above description, the adjustment of the mixing ratio of hot and cold water by rotating the outer cylinder and the flow rate adjustment by moving the inner cylinder up and down can be performed completely independently and independently of each other. There is no mutual interference between adjusting the mixing ratio of hot and cold water and adjusting the flow rate. However, by appropriately setting the shape of the water hole of the outer cylinder and the shape of the lower end of the water control wall of the inner cylinder, it is possible to easily provide a constant relationship between the mixing ratio of the water and the total flow rate. Can be. Such hot water control has a basic configuration in which a mixing tap is provided with a rotatable outer cylinder that adjusts a hot water mixing ratio and an inner cylinder that can slide up and down to adjust a total flow rate, in a valve body. That can be performed because of the above, and based on the above basic configuration,
It is also possible to easily realize the stable water stoppage and prevent the water hammer as described below.

防止することができる。That is, in the mixing tap, a valve element for opening and closing a valve seat provided in a flow passage communicating with a hot and cold water outlet of a valve body is suspended from the inner cylinder with a play in connection between the two. When,
When the inner cylinder is moved downward for water stoppage, before the through hole of the outer cylinder is closed by the water control wall of the inner cylinder, the valve seat of the hot and cold water outlet is closed by the valve body with play, Since the water pressure in the inner cylinder acts on the valve body, stable water stop of the valve body can be realized by the self-tension due to the water pressure. Further, according to the above configuration, before the valve seat is closed by the valve body, the through hole of the outer cylinder is brought into a state close to being closed by the water control wall of the inner cylinder, so that the valve seat is rapidly closed by the valve body. This can prevent a water hammer.

ができる。Basically, when one of the through holes 16 communicates with the hot water supply inlet 2 of the valve body 1 at the maximum flow opening by the rotation of the outer cylinder 11, the other of the through holes 16 and 17 is the other. When the through hole 17 is not in communication with the feed water inlet 3 in the valve body 1, and when the through hole 17 communicates with the feed water inlet 3 in the valve body 1 at the maximum flow opening, the through hole 16 Are in non-communication with the hot water supply inlet 2 of the valve body 1, and at the intermediate positions thereof, the hot water supply inlet 2 and the water supply inlet 3 are respectively connected to the through holes 16, at a rate corresponding to the rotational position of the outer cylinder 11. 17 is formed.
Therefore, depending on the rotation position of the outer cylinder 11, the through holes 16,
The ratio of the inflow area from 17 varies, and therefore, the mixing ratio of hot and cold water can be arbitrarily adjusted. Incidentally, in relation to the shapes of the inlets 2 and 3, by appropriately setting the shapes of the through holes 16 and 17, the flow rate of hot and cold water is not changed proportionally to the rotation angle of the outer cylinder 11 and is appropriately functionally adjusted. Can be changed to

An upwardly projecting shaft 22 is provided. This inner cylinder 2
1 is a through hole 16, 1 of the outer cylinder 11 which is moved up and down.
7 is configured as a cylindrical water control wall that can be opened and closed from the inside. When the shaft 22 reaches the upper end while being in contact with the outer cylinder 11 due to the vertical movement of the shaft 22, the lower end of the inner cylinder 21 that forms the water control wall is moved outward. Positioned above the through holes 16 and 17 of the cylinder 11, the through holes 16 and 17 are fully opened. Conversely, when the inner cylinder 21 reaches the lower end, the through holes 16 and 1 of the outer cylinder 11
7 are fully closed, and when the inner cylinder 21 is at an intermediate position between the upper end and the lower end, the through holes 16,

１７からの湯水の混合比を増減させることもできる。When the inner cylinder 21 is moved up and down, the space between the upper surface of the inner cylinder 21 and the upper surface of the outer cylinder 11 needs to be communicated with the outside for breathing. Therefore, a small hole (a plurality of holes) 27 for providing a braking action is formed in the upper surface wall of the inner cylinder 21. This small hole 27
Although a hole having a simple constant inner diameter can be used, as shown in the drawing, one of the ports can be opened in a tapered shape to give a difference in direction to the braking action. The total flow rate adjusted by the vertical movement of the inner cylinder 21 is the inner cylinder 2
When 1 reaches the upper end, the maximum is reached, and when it reaches the lower end, the outflow of hot water is stopped, during which the adjustment is steplessly performed. At this time, generally, the opening is performed while the ratio of the openings of the through holes 16 and 17 is kept constant depending on the position of the outer cylinder 11. The opening ratio of the two through holes 16, 17 is changed according to the vertical movement position of the two through holes 16, 17, and the two through holes 16, 17 are changed according to the total flow rate.
The mixing ratio of hot and cold water from 17 can also be increased or decreased.

Is supported on the upper part of the cylindrical shaft part 15 of the outer cylinder 11 by the support shaft 35 so as to be vertically tiltable, and the intermediate force point part 33 is
The pair of engagement grooves 25 provided on the upper part of the shaft 22 of the inner cylinder 21 are engaged as a unit that can be integrally moved up and down and relatively unrotatable. The operation unit 34 protrudes from the main body. Therefore, the rotation of the operation lever 31 rotates the outer cylinder 11 to adjust the mixing ratio of the hot and cold water, and the vertical operation of the operation lever 31 raises and lowers the inner cylinder 21 and the total amount of the hot and cold water flowing out of the hot and cold water outlet. Is adjusted. Since the outer cylinder 11 is held by restraining the vertical movement of the outer cylinder 11 with respect to the valve body 1, the outer cylinder 11
Does not move up and down.

材２３の損耗を抑制できる点で有利になる。More specifically, when the operation portion 34 is rotated left and right in a horizontal plane to adjust the mixing ratio of hot and cold water, that is, to rotate the outer cylinder 11, the operation lever 31 is a valve. A pair of the outer cylinder 11 and the inner cylinder 21 inserted into the main body 1 are integrally rotated around the axis of the shaft 22. Therefore, the distal end portion 32 of the operation lever 31 is connected to the outer cylinder 11. With the intermediate power point 33
, The inner wall of the engagement groove 25 of the shaft 22 is sandwiched by the power point portion 33 so as not to rotate relative to the shaft 22. Since the rotation of the inner cylinder 21 is irrelevant to the adjustment of the mixing ratio of hot and cold water, it is
Although it is not always indispensable to rotate them integrally, it is more advantageous to rotate them integrally because the wear of the seal member 23 can be suppressed.

As described above, the front end portion 32 of the first operating portion 31 is supported on the upper portion of the outer cylinder 11 by the support shaft 35 so as to be tiltable up and down, and the intermediate force point portion 33 of the operating lever 31 moves freely in the engaging groove 25 of the shaft 22. They are freely engaged. The engagement of the power point portion 33 needs to allow the tilt in order to tilt the operation lever 31 by moving the operation portion 34 of the operation lever 31 up and down. The force point portion 33 engages with the engaging groove 2
In order to move along 5, it is necessary to allow the movement. Therefore, as shown in the drawing, the power point portion 33 of the operation lever 31 can be loosely fitted and engaged with the engagement groove 25 of the shaft 22 with a margin, but the operation lever 31 is When the pin is rotatably mounted by, for example, it is necessary that the pin can be moved in parallel in a direction perpendicular to the axis of the shaft 22.

も有効に機能するものである。In the hot and cold water mixing tap having the above structure, the valve element 4
When 1 closes the valve seat 5, hot water is introduced into the upper surface of the valve body 41 inside the inner and outer cylinders, so that the pressure of the hot water is applied to the valve body 41 when the valve body 41 is fully closed. The pressure tightly adheres to the valve seat 5 and exerts a so-called self-tension, thereby exhibiting a stable and effective water stopping effect. On the other hand, when the valve element 41 closes the valve seat 5, the shaft 22
The pressure of the hot and cold water acts on the cross-sectional area of the portion of the outer cylinder 11 that is fitted into the cylindrical shaft portion 15 of the outer cylinder 11, but this force is reduced by reducing the cross-sectional area to the frictional force of each part. And can be relatively small, and
When the valve body 41 is slightly opened by the operation of the operation lever 31, the pressure of the hot and cold water acting on the shaft 22 is reduced, so that the pushing force on the shaft is reduced and the operation of the shaft 22 is not adversely affected. The small holes 27 formed in the upper wall of the inner cylinder 21 act as a braking force on the inner cylinder 21 to provide resistance to the flow of hot and cold water passing therethrough when the inner cylinder 21 moves up and down. And also effectively functions to stabilize the holding of the position of the inner cylinder 21.

That is, the valve body 41 for opening and closing the valve seat 5 provided in the flow path 4 of the valve main body 1 is suspended from the inner cylinder 21 with play in the connection between the two, so that the water is stopped for stopping water. When the inner cylinder 21 is moved downward, before the valve seat 5 is closed by the valve body 41 with play, the water blocking wall of the inner cylinder 21 causes the through holes 16 and Since the valve 17 is in a state close to the closing, the valve seat 5 is not suddenly closed by the valve element 41, thereby preventing a water hammer. Further, since the opening and closing of the valve element 41 is performed from the shaft 22 via the flexible member 42, the valve element 41 is not forcibly pressed against the valve seat 5 by the shaft 22. In combination with the fact that rotational friction does not occur, the durability of the valve body 41 can be improved.
