ハンマーが発生し易いという欠点がある。However, in such a single lever type hot and cold water mixing apparatus, the lever handle 21 is used.
Since the vertical operation width of is generally small and it is only 23 degrees in the example of the figure, it will be fully opened or closed at once, so it will be very difficult to adjust the flow rate, and from full open to full close in a short time. Since it moves, it has the drawback that water is abruptly stopped and water hammer is likely to occur.

There is no safety stopper even if 1 is operated to the high temperature side.
Since there is nothing to detect the temperature position by touch, there is a risk that hot water may be suddenly discharged and burns may occur due to an erroneous operation. Furthermore, since the spout water and temperature control are operated by the same lever handle, the lever handle will move to the left and right at the same time even if you try to operate the lever handle only up and down to stop spouting water, at the same temperature. However, there is a drawback that it is difficult to re-water and the operability is not good.

1にその触感が得られるようにしている。Embodiments of the present invention will now be described with reference to the drawings. In the embodiment shown in FIGS. 4 and 5, the movable valve 12 of the hot and cold water mixing apparatus shown in FIGS. 1 and 2 is provided with an elastic body, and the fixed valve 11 is provided with an uneven portion for engaging and disengaging the elastic body. It will be.
That is, as shown in FIG. 4, a vertical hole 30 is formed near the center rear of the movable valve 12, a coil spring 31 is inserted in the vertical hole 30, and a hard ball 32 slides on the fixed valve 11 by the elasticity of the coil spring 31. As shown in FIG. 5, the fixed valve 11 is elastically pressed against the contact surface, and a spherical concave portion 33 is formed as an uneven portion in the range where the hard ball 32 can come into contact with the movable valve 12 by the forward / backward movement and the rotational movement of the movable valve 12, as shown in FIG. When the movable handle 12 is moved back and forth and rotated by operating the lever handle 21 up and down and left and right, the hard balls 32 engage and disengage from the spherical recesses 33, thereby adjusting the flow rate and adjusting the temperature. Sometimes the lever handle 2
It is designed so that the touch feeling can be obtained.

で流量調節時のみその係合離脱の感触が得られる。In the embodiment of the fixed valve 11 shown in FIG. 5, the feel of engagement and disengagement of the hard balls 32 can be obtained during both the flow rate adjustment and the temperature adjustment, but as shown in FIG. When a large number of concave grooves 34 are radially formed in the concave-convex portion 11 as shown in FIG. 11, the hard balls 32 are engaged with and disengaged from the concave grooves 34 only when the movable valve 12 is rotated, so that the feeling of engagement and disengagement can be obtained only when the temperature is adjusted. To be For this reason, this form is desirable when stopping water discharge without changing the temperature of the mixed water or when adjusting the flow rate. Further, in the embodiment shown in FIG. 7, three fixed concentric grooves 35 are formed in the fixed valve 11, and the movable valve 12
Since the hard ball 32 engages and disengages with the concave groove 35 only when moving forward and backward, the feeling of engagement and disengagement can be obtained only when the flow rate is adjusted.

る。Further, the embodiment shown in FIGS. 8 and 9 has a large number of grooves 36 formed radially as in the case of FIG.
In FIG. 8, when the lever handle 21 is operated to the left so that the temperature of the mixed water becomes high, the groove 36 is formed such that the pitch of the groove 36 is gradually reduced to form a small pitch. When the operation is performed to the high temperature side, the feeling of engagement and disengagement of the hard balls 32 is obtained at a narrower interval, and the operator is naturally given a caution signal that the hot water of high temperature is discharged. In FIG. 9, for the same reason, the depth and width of the concave groove 36 are made larger toward the high temperature side and the undulations thereof are made larger so that a larger engagement / disengagement feeling can be obtained as the lever handle 21 is operated to the higher temperature side. It was done like this.
【0016】なお、図6,図8,図9では温度調節の全

が行なわれるようにしてもよい。Although FIG. 6, FIG. 8 and FIG. 9 show an example in which a large number of concave grooves are formed over the entire range of temperature adjustment, concave and convex portions such as concave grooves are formed only on the high temperature side to discharge hot water. Only a warning may be given.

できる。Further, in the example shown in FIG. 7, three concave grooves 35 are provided.
Although the feel of engagement and disengagement can be obtained over substantially the entire flow rate adjusting range by providing the above, as shown in FIG. 10, the concaves with which the hard balls 32 engage when the flow rate of the mixed water is controlled to a small amount. Even if only one groove 35 is formed, the engagement and disengagement of the groove 35 immediately before the water stop can reduce the water stop speed, thereby suppressing the generation of the water hammer.

The lever handle 21 of the hot and cold water mixing device shown in FIG. 2 is provided with an elastic body, and the tightening cylinder 19 is provided with an uneven portion. That is,
As shown in FIG. 11, a vertical hole capable of accommodating the coil spring 31 is bored in the inner surface of the base of the lever handle 21 that covers the tightening cylinder 19, and the hard ball 32 is elastically protruded from the opening edge of the vertical hole while tightening. The outer peripheral surface of the cylinder 19 is formed in a spherical shape centered on the pin 14, and a large number of hemispherical recesses 33 are vertically and horizontally arranged on the surface thereof as shown in FIG. Therefore, in this case, if the lever handle 21 is operated vertically or horizontally, the hard ball 3
2 engages with and disengages from the hemispherical concave portion 33, and the feel is obtained by the lever handle 21.

The feel of engagement and disengagement is obtained only when the disengagement is performed and the flow rate is adjusted. Further, in the tightening cylinder 19 shown in FIG. 14, a large number of concave grooves 36 are radially formed on the outer peripheral surface thereof at a constant pitch, and the hard balls 32 are provided only when the lever handle 21 is rotated left and right to adjust the temperature. Can be engaged with and disengaged from the groove 36.

出に対する注意を促すことができるようになる。In the example shown in FIGS. 15 and 16, the engaging member 37 is fixedly fixed to the engaging piece 48 projecting from the upper end surface of the tightening cylinder 19, and the outer periphery of the tightening cylinder 19 of the engaging member 37 is fixed. The part that can cover the surface is made spherical and the hemispherical recess 33 is formed on the surface. As shown in FIGS. 12 and 14, the tightening cylinder 19
When the concavo-convex portion is directly formed on the product, the stop position of the tightening cylinder 19 when screwed onto the tubular upright portion 4 varies depending on the product, and therefore the position of the concavo-convex portion with which the hard ball 32 engages and disengages. There is an inconvenience that the value does not become constant, but in FIGS.
If the engaging member 37, which is a separate member, is fixed to this as shown in FIG. 7, the position of the concave-convex portion, that is, the hemispherical concave portion 33 becomes constant, so that the embodiment shown in FIGS. Similarly to the above, the feeling of engagement and disengagement can call attention to the discharge of high-temperature hot water.
