止されて位置する。The control valve portion B is a spool 35 having a spool case 36 and a temperature-sensitive stretchable body (wax pellet) 34.
Consists of The spool 35 is slidably inserted into the case 36 so as to be slidable left and right, and is constantly urged in the leftward direction by a spring 37. The spool case 36 is screwed and fastened 30 to the right end of the spindle case 19 on the left end side, and is fitted into the housing. The spool case 36 has a circumferential water inflow mechanism (slit-like shape) 38 formed in a part of the outer peripheral surface of the housing, which is located in the supply water chamber, and is further provided on the outer peripheral surface of the housing located in the supply water chamber. A hot water inflow structure (slit-shaped) 39 is provided in the circumferential direction in the portion. Further, a discharge port 40 is formed in the circumferential direction near the right end of the spool case 36. The spool 35 has a water valve 3 at the front and rear ends.
1 and the hot water valve 32 are formed, and a water inlet 31 is formed by the water valve 31 and the annular water valve seat 36a formed in the spool case 36, and is integrated with the hot water valve 32 and the movable plug 41. The hot water inflow path H is formed by the hot water valve seat 41a formed on the valve body.
To form The spool 35 has a temperature-sensitive stretchable body 34 screwed to a boss portion 35b having a water passage hole 35a. The large-diameter temperature sensitive portion 34a is arranged in the mixed hot water passage 41c of the movable plug 41, and the tip of the protrusion 34b is brought into contact with the disc 27. The protrusion 34b protrudes and retreats in response to expansion and contraction of the enclosed wax due to the temperature, and the amount of protrusion and retreat is uniquely and directly proportional to the amount of change in the mixed water. The return spring 37 has a large bulging diameter of the temperature-sensitive expandable body 34 and the movable stopper 41 in the hollow portion of the movable stopper 41.
Is inserted in a state of diagonally crossing the mixed hot water passage 41c so as to mix and stir hot water and water.
Since the urging force of the return spring 37 is set to be smaller than the urging force of the relief spring 26, the disc 27 is positioned in pressure contact with the stopper ring 29 during normal operation.

The left end of the movable valve body 41 that receives the repulsive elastic force is inserted into the spool case 36 so as to be slidable from side to side. Further, a plug case 42 is fitted around the right end of the movable valve body 41. Then, an adjusting screw 43 is screwed into the stopper case 42 near the center of the rear end thereof, and the movable stopper 41 is moved forward and backward by moving the adjusting screw 43 forward and backward. Stopper 45
Is the movable stopper 4 caused by turning the flow rate setting handle 46 too much.
1 is prevented from being over-tightened and the movable stopper 41 is prevented from rotating, and damage to the valve bodies 31 and 32 and the packing is prevented. The movable plug 41 moves the water valve seat 3 as the adjusting screw 43 moves back and forth due to the rotation of a flow rate setting handle (not shown).
The distance L between the hot water valve seat 41a and 6a is changed to adjust the amount of hot and cold water mixed.

材の摩耗が増えるいう課題があった。However, in the conventional hot and cold water mixing apparatus as described above, the movable plug 41 is slid in the axial direction, so that the sliding resistance between the movable valve body 41 and the sealing material becomes large. There is a problem that the operability deteriorates and the wear of the sealing material increases.

ばらつきが生じる可能性があった。Further, by bringing the spool 35 into contact with the water valve seat 36a and the hot water valve seat 41a to provide a closing function, the contact surfaces of the spool 35, the water valve seat 36a and the hot water valve seat 41a are precisely formed. However, the elastic member must be used on both ends of the spool 35 or the contact surfaces of the hot and cold water valve seats 36a and 41a. For this reason, the processing cost is high, and when the elastic member is used, it is difficult to obtain precise dimensional accuracy, which may cause variations in the hot and cold water mixing ratio.

Needed a separate switching valve.

湯温が変動するという課題があった。In addition, when the distance L between the water valve seat 36a and the hot water valve seat 41a is changed to adjust the amount of hot and cold water mixture,
Since the spool 35 is also driven at the same time, there is a possibility that the opening area ratio of the hot and cold water may change from that before the flow rate change. That is,
After adjusting the amount of mixed hot water, the temperature-sensitive stretchable body 34 expands and contracts,
There was a problem that the mixed hot water temperature fluctuated during the time until the opening area ratio of the hot water was returned to the original state.

Since the biasing force of each changes, the opening area ratio after expansion and contraction of the temperature-sensitive expansion / contraction body 34 becomes a ratio different from that before the flow rate is changed due to the hysteresis, and the mixed hot water temperature is maintained in a changed state, There was a possibility that the temperature of the mixed hot water before setting could not be restored.

合湯温が変動しない。The hot and cold water mixing apparatus of the present invention has the above-described structure.
Since the flow valve element is driven to rotate when adjusting the flow rate of the mixed hot water, sliding resistance can be reduced. Further, since the flow rate can be adjusted without driving the valve seat and the valve body of the mixing valve in the direction of changing the opening area ratio of the hot water, the mixed hot water temperature does not change.

When adjusting the flow rate of hot water, stopping water flow, and switching the flow path,
The opening area ratio of hot and cold water does not change. Therefore, the hot water temperature does not fluctuate during the flow rate adjustment and the flow path switching, and the previous hot water temperature can be maintained even when the hot water is again discharged after the water is stopped.

Since the means is controlled, even if the temperature deviation due to the pressure fluctuation of the hot water or the hysteresis of the biasing means occurs, the temperature is corrected without performing the operation by the feedback control. In addition, since the sliding resistance is reduced by not driving the flow valve element in the axial direction, it is possible to use a low-cost and compact flow rate operating means, and in flow rate adjustment, water stoppage, and flow path switching operations. Can improve usability.

The hot water mixing ratio can be adjusted by mechanical feedback control. Further, even if the hot and cold water mixing ratio changes before the hot water temperature change due to the hysteresis of the temperature sensitive body, the mechanical feedback control is performed, so that the adjustment amount of the biasing force adjusting means can be greatly suppressed.

Can be set to a desired temperature by rotary drive. The biasing force adjusting means 64 is connected to the male screw shaft 66 via the hot water valve seat 57 fixed to the housing 53 by the screw portion 65, and is driven only in the rotational direction. The male screw shaft 66 is provided with a male screw portion 66a on the opposite side of the urging force adjusting means 64, and is screwed with a movable spring receiver 67 having a female screw portion 67a that advances and retreats as the male screw shaft 66 rotates. That is, by rotating the urging amount adjusting means 64, the male screw shaft 66 rotates in accordance with the amount of operation, and the movable spring receiver 67 moves back and forth in the axial direction. At this time, as the movable spring receiver 67 moves back and forth, the biasing force of the bias spring 63 is adjusted (the restraint length changes), so that the balance of the biasing force with the temperature-sensitive coil spring 62 is lost and the temperature-sensitive coil spring is broken. The movable valve body 60 is moved to a position where the biasing forces of the bias spring 63 and the bias spring 63 are balanced, and the mixing ratio of hot and cold water is changed according to the operation amount of the biasing amount adjusting means 64.

The coil spring 62 is moved to a position where the urging force of the coil spring 62 is balanced. That is, the temperature-sensitive coil spring 62 performs mechanical feedback control in which the biasing force changes and the mixed hot water temperature is adjusted even if some disturbance occurs and the mixed hot water temperature fluctuates.

Has been done. That is, when the actual mixed hot water temperature is lower than the biasing force of the bias spring 63 which is set to the desired temperature set by the biasing force adjusting means 64, the biasing force of the temperature sensitive coil spring 62 is smaller and the hot water valve The movable valve body 60 is moved in a direction in which the gap distance between the seat 57 and the movable valve body 60 is widened and the gap distance between the water side valve seat 56 and the movable valve body 60 is narrowed.

The water-side valve seat 56 and the water-side valve seat 56 are integrally formed, but they are not driven in the axial direction.
The axial distance of 7 does not change. Therefore, the mixing valve 59
The gap of is not changed, and the mixing ratio of hot water is not changed. Further, even if the flow valve body 71 is rotationally driven,
Since the sheet member 69 and the temperature-sensitive coil spring 62 slide smoothly, the temperature-sensitive coil spring 62 is not twisted. That is, even if the flow rate is adjusted and the flow path is changed, the biasing force of the temperature-sensitive coil spring 62 does not change and the movable valve body 60 does not move, so that the hot-water mixing ratio is maintained.

に、低コスト化が実現できる。As described above, according to this embodiment, since the water valve seat 56 of the mixing valve 59 is formed in the flow valve body 71 of the flow valve 70, the number of parts can be greatly reduced. Since a space for the flow valve 70 is not required separately from the mixing valve 59, it is possible to provide a compact hot and cold water mixing device. In addition, since the hot water side valve seat 57 and the water side valve seat 56 are separate parts from the housing 53, the processing process of the housing 53 can be simplified, the number of parts can be reduced, and the cost can be reduced.

Since the biasing force of the temperature sensitive coil spring 62 does not change, the opening area ratio of hot and cold water is maintained. In addition, when the closing and opening operations are repeated (that is, when hot water is left again before the temperature of the mixed hot water left in the mixing passage and the temperature of the hot water supplied in the hot water supply pipe have dropped), closing and opening are performed. Since the movable valve element 60 is not driven by the operation, the opening area ratio of the hot water can be maintained and the hot water temperature fluctuation at the time of re-hot water can be prevented.

By providing the coil spring 62, the mixed hot water surely comes into contact with and passes through the temperature-sensitive coil spring 62, and the spring constant of the temperature-sensitive coil spring 62 changes according to the mixed hot water temperature. Is fluctuated by disturbance,
Immediately, the mechanical feedback control is performed to the desired temperature set by the bias amount adjusting means 64. Therefore, feedback control can be automatically performed, and a compact hot and cold water mixing apparatus can be provided. Even if the first urging means is a temperature sensitive wax pellet or a temperature sensitive coil spring made of bimetal, the same effect can be obtained although there is a difference in response time.

駆動する。In the above structure, only the operation different from that of the hot and cold water mixing apparatus 70 of the first embodiment will be described. When the desired hot water temperature is set by the hot water temperature setting means 96, the control means 94 rotates the urging force adjusting means 88 in accordance with the set temperature to adjust the urging force of the bias spring 63 to thereby move the movable valve. The body 60 is moved to a position according to the set temperature. When the shower-side hot water is selected by the flow rate setting means 97, the control means 94 rotationally drives the flow rate operation means 93, and the flow rate valve 70.
From the closed state, open the shower side as shown in FIG. 4, and start tapping. Even when the flow rate setting means 97 selects another flow rate change, closing, or flow path switching, the control means similarly rotationally drives the flow rate valve element 91 to the corresponding position.

移動され、混合湯温が調節される。When the flow valve 70 is opened, hot water and water are supplied from the water inflow path 54 and the hot water inflow path 55 to the movable valve body 60.
According to the gap between the water side valve seat 56 and the hot water side valve seat 57, they flow into the inside of the movable valve body 60 and are mixed. At this time, as described in the first embodiment, the mechanical feedback control is performed by the temperature sensitive coil spring 62 so that the temperature of the mixed hot water becomes the set temperature. At the same time, the control means 94 inputs the mixed hot water temperature detected by the thermistor 90, and calculates the deviation between the set hot water temperature set by the hot water temperature setting means 96 and the mixed hot water temperature. When the detected mixed hot water temperature has a deviation higher than the set temperature, the control means 94 drives the biasing force adjusting means 88 in the positive direction by a predetermined biasing amount according to the absolute value of the deviation, and the movable spring receiver 67. To the left. Therefore, since the biasing force of the bias spring 63 is reduced, the hot water valve seat 5
The movable valve body 60 is moved in a direction in which the gap distance between the movable valve body 60 and the water-side valve seat 56 is narrowed, and the mixed hot water temperature is adjusted.

り正確な温度調節が可能となっている。On the contrary, when the detected mixed hot water temperature has a deviation on the side lower than the set temperature, the control means 94 drives the urging force adjusting means 88 in the reverse direction by a predetermined urging amount corresponding to the absolute value of the deviation. Then, the movable spring receiver 67 is moved to the right. Therefore,
Since the biasing force of the bias spring 63 is increased, the gap distance between the hot water valve seat 57 and the movable valve body 60 is increased,
The movable valve body 60 is moved in the direction in which the gap distance L between the water side valve seat 56 and the movable valve body 60 is narrowed, and the temperature of the mixed hot water is adjusted. Thus, in addition to the mechanical feedback control by the action of the temperature-sensitive coil spring 62, the control means 94 drives the biasing force adjusting means 88 in accordance with the deviation between the mixed hot water temperature detected by the thermistor 90 and the set temperature. Since the electric feedback control for operating the movable valve body 60 is performed, more accurate temperature adjustment is possible.

る。In addition, the flow rate valve body 91 is configured to be driven only in the rotational direction with respect to the axis, and the flow rate valve body 9
Since the O-rings 75 and 76 provided in No. 1 do not slide on the housing 53 but slide on the flow valve body 71, the sliding resistance of the flow valve body 71 can be reduced. Therefore,
Since the required rotational torque of the electrically driven flow rate operating means 93 is greatly reduced, downsizing of the flow rate operating means 93,
Cost reduction can be realized. When a motor is used as the flow rate operating means 93, it is not necessary to convert the rotational driving force into a driving force in the axial direction, so that the loss of the driving force of the motor can be suppressed to the minimum and the flow rate can be reduced. Disc 91
It is possible to simplify the configuration of the fitting portion of the flow rate operating means 93.

Since the electric feedback control is performed by the control unit 94 which drives the biasing force adjusting unit 88 according to the deviation of the hot water temperature, the temperature can be adjusted more quickly and accurately. That is, since the electric feedback control corrects the deviation of the mechanical feedback control such as the operation hysteresis of the temperature sensitive coil spring 62 and the bias spring 63,
