る。However, although the rotation of the operation lever is stepless and smooth, the water mixer tap has a weight of the rotation operation of the operation lever and a discharge port at the stop position of the operation lever depending on the manufacturer. If the amount of water or the temperature of the water is different, for example, if the rotation of the operation lever is too light, too much force will be applied and the operation lever will be fully opened, or if you use a water tap different from the one you always use, It is difficult to stop the lever at the proper water discharge position. If the operation lever is fully opened as described above, there is a possibility that the water and hot water will be scattered due to too strong a water discharging force and wet clothes, or suddenly hot water will be discharged. However, in such a situation, the operation of rotating the operation lever to an appropriate amount of the water discharging position is delayed because the operation lever is inevitably delayed. When the operator releases his / her hand, the operation lever may be accidentally rotated, and water may be spouted at a force higher than desired or at a high temperature, or may be closed. In particular, in the case of elderly people who are slow-moving, have heart disease, or have physical disabilities, the operation lever is fully opened. There is a danger of burns and heart attacks if hot water is discharged, for example. In addition, since the visually impaired person cannot visually recognize the operation lever, the operation of the lever is likely to be erroneous, and it is extremely inconvenient to adjust the amount of discharged water or the temperature of hot water, and the risk described above is high. In addition, when the rotation of the operation lever is heavy, it is more difficult for the elderly and the physically handicapped to stop the operation lever at an appropriate amount of the water discharge position than for a healthy person, in terms of operability. There's a problem. Furthermore, if a large amount of water is discharged, not only the person himself / herself, but also a family member and an attendant will require a great deal of labor. Moreover, when used for sinks, etc., when storing water in deep or shallow dishes, such as tableware of different sizes, or when washing them, spouting suitable for dishes of various sizes is performed. It is difficult to perform, and the amount of water discharged is small for large and deep dishes, and it takes time to store and wash, or the amount of water discharged is too large for small and shallow dishes, and the water splatters Sometimes, if you accidentally touch the operation lever in the middle of washing, for example, when you are trying to stop the water in a hurry because you are spouting more power than you want, you can drop and wash the dishware and break it There is a risk of getting it. As described above, the conventional hot-water mixer tap has the convenience of being operated with one hand,
There is a problem that it is difficult to quickly adjust a proper amount of water.

品交換等も非常に容易である。The present invention has the following advantages by the above configuration. (Claim 1) The operation lever can be alternately held and released from a plurality of stop positions at predetermined positions during its rotation by holding means arranged to act on the lever. According to the above, at a predetermined position during the rotation of the operation lever, the holding means always acts to stop the operation lever, and the operation of stopping the operation lever resists the rotation of the operation lever operated by the user. Appears as. In other words, the resistance of the holding means serves as a marker of the stop position of the operation lever for the user, and the user rotates the operation lever while sensing the resistance. Therefore, the user can confirm the stop position of the operating lever by sensing the resistance, and since the holding means functions as a stopper, not only the user who is not used to the single lever type hot and cold water mixing tap, but also the elderly and Even if the user is physically handicapped, it is possible to prevent excessive rotation of the operation lever regardless of the weight of the rotation of the operation lever, and quickly and easily adjust the water discharge amount and hot water temperature that are well-suited. In addition to avoiding dangers such as burns and heart attacks, the operability for users who cannot see the control lever can be sensed as if the stop position of the control lever is transmitted to their hands even when operated by visually impaired people. It is very effective in improving safety. In addition, when used for sinks,
Since the appropriate amount of water discharge according to the size of the tableware can be secured, water can be stored and washed quickly and without wasting water, and even if the operation lever is accidentally touched, the operation lever stopped by the holding means is Since it is immobile, it is possible to prevent sudden increase / decrease of the set spout. Furthermore, since the operation time at the time of operating the operation lever can be shortened, it is very effective in eliminating waste of water during the operation. (Claim 2) When the operating lever is rotated in the opening direction and the hot water temperature adjusting direction, the rotating cylinder rotates with respect to the main body and the connecting rod rotates in the front-rear direction with respect to the rotating cylinder. The movable plate slides with respect to the fixed plate, and the hot water inflow path, the water inflow path, the hot and cold water outflow path in the fixed plate, and the rotating cylinder and the connecting rod in the hot / water mixing tap such that the water passage in the movable plate communicates. Since the holding means is operated, the rotation of the rotating cylinder and the connecting rod directly slides the movable plate for adjusting the water discharge amount and the hot water temperature. The position of the movable plate at the predetermined position is always kept constant without shifting. Accordingly, the setting of the predetermined position where the holding means acts on the operation lever and the position of the movable plate at the predetermined position is maintenance-free semipermanently. (Claim 3) In addition, since the holding means has a simple structure in which the engaging projection and the engaging recess are elastically disengaged from each other, the holding means can be held and held. In addition to being possible at a low cost, it is very easy to repair or replace parts when a failure occurs.

作レバー11の過剰回動を防止することができる。[0013] The hot and cold water mixing tap is operated by an operating lever.
When the motor 11 is stopped at the predetermined position set as described above, the engaging projection 63 is engaged with the engaging recess 64, and the engaging force is held by the urging force of the compression spring 62. When the operating lever 11 is turned from this state, the connecting rod 4 and the turning cylinder 5 are turned, and the engaging projections ride on the inner peripheral surface of the main body 12 against the urging force of the compression spring 62. Disengage. Therefore, the rotation of the operation lever 11 is controlled by the holding means 6 so that the amount of water discharged is “large”, “medium”, “small”.
Since the water temperature is stopped at the three stages of "high", "medium", and "low", respectively, it is possible to quickly adjust the water discharge amount and the temperature of the well-conditioned water, Excessive rotation of the operation lever 11 can be reliably prevented.

実に防止できる。（図示せず）The setting of the holding means 6 is not limited to the three stages described above, and the setting is such that when the water is over the position, the water is scattered and the holding means operates at a dead point where the temperature of the hot water becomes too hot. If you do this,
At least excessive rotation of the operation lever can be reliably prevented.
(Not shown) In addition, the holding means operates continuously over the entire rotation range of the operating lever 11 so that the operating lever 11 is always held by the holding means 6.
May be set to be held. In this case, if a ratchet mechanism that rotates in both the forward and reverse directions of the uneven engagement that elastically engages and disengages is used, the engagement and disengagement of the unevenness in the ratchet mechanism is performed continuously with the rotation of the operation lever.
Fine adjustment of the operation lever can be quickly performed, and the engagement and disengagement of the unevenness appears as a resistance to the rotation of the operation lever. Therefore, the excessive rotation of the operation lever can be reliably prevented even if a little excessive force is applied by the resistance. (Not shown)
