  As shown in FIG. 3, the bottom surface of the flow rate adjusting knob 6 is formed so as to extend along the arc cross section of the rotating cap 8 when the flow rate adjusting knob 6 is attached to the shaft 20. As a result, the opening 8 c of the rotation cap 8 is covered with the flow rate adjusting knob 6. Further, as described above, the arc section of the rotation cap 8 is formed in an arc shape centering on the rotating shaft 12b of the adjusting rod 12a. For this reason, when the adjustment rod 12 a is rotated about the rotation shaft 12 b, the flow rate adjustment knob 6 is moved along the arc cross-section of the rotation cap 8.

  Here, the distance D2 from the first axis V to the tip of the flow rate adjusting knob 6 is the longest when the hot and cold water mixing faucet 1 is fully opened (maximum flow rate). In the present embodiment, the distance D1 from the first axis V to the protruding end of the temperature adjusting lever 8a is always longer than the distance D2 from the first axis V to the protruding end of the flow rate adjusting knob 6. Has been. Therefore, when the user grips the temperature adjustment lever 8a, a large torque around the first axis V can be easily applied to the adjustment rod 12a. When the flow rate adjusting knob 6 is gripped, it is difficult to apply a large torque to the adjusting rod 12a. Thereby, it is possible to prevent the adjustment rod 12a from being accidentally rotated about the first axis V by the operation of the flow rate adjusting knob 6.

  Next, with reference to FIG. 3, FIG. 4 and FIG. 11, the internal configuration of the hot and cold water mixing valve unit 12 will be described. FIG. 11 is a cross-sectional view of the hot and cold water mixing faucet 1 in a water-stopped state. As shown in FIG. 11, the hot and cold water mixing valve unit 12 includes an adjustment rod 12 a, a cover 24, a fixed disk 26 accommodated in the cover 24, and a movable disk 28 movable with respect to the fixed disk 26. And having.

  The adjustment rod 12a is configured to be rotatable about a rotation shaft 12b (second axis H) oriented in the horizontal direction. The rotating shaft 12b is configured to be rotatable about a first axis V passing through the center of the hot and cold mixing valve unit 12 with respect to the cover 24. Therefore, the adjustment rod 12a is supported so as to be rotatable about the first axis V while being rotatable about the rotary shaft 12b.

  The fixed disk 26 is a substantially disk-shaped member in which the hot water inlet 12 c, the water inlet 12 d, and the outlet 12 e are formed, and is fixed to the cover 24. The hot water inlet 12c and the water inlet 12d are configured so as to be aligned with the two hot water supply passages 10c and 10d provided in the casing 10, respectively. 12c, it flows in through the water inlet 12d.

  The movable disk 28 is a substantially disk-shaped member, and a rod receiving recess 28a is formed on the upper surface thereof, and a water passage recess 28b is formed on the lower surface thereof. The rod receiving recess 28a receives the lower end portion of the adjustment rod 12a. When the adjustment rod 12a is rotated about the rotation shaft 12b, the movable disk 28 is moved back and forth with respect to the fixed disk 26 (see FIG. 11 in the horizontal direction). Further, when the adjustment rod 12a is rotated around the first axis V, the movable disk 28 engaged therewith is also rotated with respect to the fixed disk 26.

  Further, the water passage recess 28b on the lower surface of the movable disk 28 is configured to appropriately open and close the hot water inlet 12c and the water inlet 12d of the fixed disk 26 when the movable disk 28 is moved with respect to the fixed disk 26. Has been. That is, as shown in FIG. 11, when the movable disk 28 is moved to the rightmost side, the hot water inlet 12c and the water inlet 12d are completely closed by the movable disk 28 to be in a water stop state. From this state, when the adjustment rod 12a is rotated about the rotation shaft 12b and the movable disk 28 is moved to the left, the water flow through the hot water inlet 12c, the water inlet 12d of the fixed disk 26 and the movable disk 28 is passed. The recesses 28b overlap. In this state, hot water and water that have flowed in through the hot water inlet 12c and the water inlet 12d flow into the water passage recess 28b and are mixed, and then flow out of the outlet 12e to form a water discharge state. Further, in the state where the movable disk 28 shown in FIG. 3 is moved to the left most, the hot water inlet 12c and the water inlet 12d are in the most open state, and the discharged water flow rate is also maximized.

  On the other hand, when the adjustment rod 12a is rotated about the first axis V and the movable disk 28 is rotated, the opening degree of the hot water inlet 12c and the water inlet 12d changes. That is, when the temperature adjusting lever 8a (adjusting rod 12a) is rotated in the direction of the arrow H in FIG. 2, the opening degree of the hot water inlet 12c communicating with the hot water supply passage 10c is increased. The opening degree of the inlet 12d is reduced. Thereby, since the inflow amount of water decreases and the inflow amount of hot water increases, the temperature of the hot water discharged becomes high. On the other hand, when the temperature adjusting lever 8a is rotated in the direction of arrow C in FIG. 2, the inflow amount of water increases and the inflow amount of hot water decreases, so the temperature of the discharged hot water decreases. . As shown in FIG. 11, when the movable disk 28 is moved to the rightmost side, the hot water inlet 12c and the water flow can be obtained even if the adjusting rod 12a is rotated about the first axis V. The inlet 12d remains closed and the water stop state is maintained.

  Next, the operation of the hot and cold water mixing faucet 1 according to the first embodiment of the present invention will be described. First, in the water stop state shown in FIG. 11, since the movable disk 28 closes the hot water inlet 12c and the water inlet 12d provided in the fixed disk 26, the hot water supply path 10c and the water supply path 10d are used. The supplied hot water and water do not flow into the hot / cold water mixing valve unit 12 and are in a water-stopped state. Next, when the flow rate adjusting knob 6 (adjusting rod 12a) is rotated in the right direction in FIG. 11 about the rotating shaft 12b (second axis H), the movable disk 28 is moved to the left, The hot water inlet 12c and the water inlet 12d are opened and water is discharged. Here, since the distance D2 from the first axis V to the raised portion 6a of the flow rate adjusting knob 6 is short, the rotating cap 8 is accidentally caused by the gripping / operation of the flow rate adjusting knob 6 by the user. The set temperature is not changed by rotating around the axis V.

  When the temperature adjusting lever 8a is directed to the front surface of the hot and cold water mixing faucet 1, the opening degree of the hot water inlet 12c and the water inlet 12d is substantially equal, and approximately the same amount of water and hot water is the hot and cold water mixing valve unit. 12 flows in. The water and hot water that have flowed into the hot water / mixing valve unit 12 are mixed and flowed out from the outlet 12e. The hot water flowing out from the outlet 12e is discharged from the water outlet 4a of the water discharger 4 through the hot water passage 10e.

  On the other hand, when the temperature adjusting lever 8a is rotated rightward or leftward about the first axis V, the entire rotation cap 8 is rotated about the first axis V. When the rotation cap 8 is rotated, the contact concave portion 8f of the rotation portion 8b and the side surface 22d of the guide portion 22 received by this contact with each other. Thereby, the guide part 22 is pressed by the contact recessed part 8f, and is rotated centering on the 1st axis line V. FIG. When the guide portion 22 is rotated, the adjustment rod 12a coupled to the guide portion 22 is also rotated around the first axis V, thereby changing the mixing ratio of the flowing hot water and water and discharging water. The temperature of the hot water is adjusted. Here, since the rotation cap 8 (temperature adjustment lever 8a) can only rotate about the first axis V, the adjustment rod can be obtained by gripping and operating the temperature adjustment lever 8a by the user. 12a is rotated around the second axis H, and the discharged water flow rate does not change.

According to the hot and cold water mixing faucet of the first embodiment of the present invention, the temperature adjusting lever is attached to the valve presser so as to be rotatable about only the first axis. By the operation, it is possible to prevent the adjustment rod from being accidentally rotated about the second axis and changing the outflow flow rate of the hot water.
Further, according to the hot and cold water mixing faucet of the present embodiment, the guide portion is attached to the adjustment rod and the contact area is enlarged, so that the surface pressure acting on the adjustment rod and the rotating portion is reduced. The durability of the hot and cold water faucet can be improved.

  Furthermore, according to the hot and cold water mixing faucet of the present embodiment, the flow rate adjusting knob is moved along the circular arc cross section of the rotating portion, so that the flow rate adjusting knob is always positioned in the vicinity of the first axis. To do. Thereby, it is possible to prevent the adjustment rod from being accidentally rotated about the first axis by gripping and operating the flow rate adjustment knob.

  In the above-described embodiment, the rotating portion and the temperature adjusting lever are integrally configured as a rotating cap. However, the rotating portion and the temperature adjusting lever are configured separately and together with the temperature adjusting lever. You may couple | bond both so that a rotation part may be rotated.

  In the above-described embodiment, the adjustment rod, the shaft, the guide portion, and the flow rate adjustment knob are configured separately. However, these members may be configured integrally or divided as appropriate. be able to.

The hot and cold water mixing faucet of the present embodiment is different from the first embodiment in the shape of the flow rate adjusting knob. Accordingly, here, only the portions of the second embodiment of the present invention that are different from the first embodiment will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

  As shown in FIGS. 12 and 13, the hot and cold water mixing tap 100 according to the second embodiment of the present invention includes a casing 10, a hot and cold mixing valve unit 12 received in the casing 10, and a hot and cold mixing valve. And a valve presser 14 for fixing the unit 12. A cylindrical spacer 16 is disposed on the outer periphery of the housing 10, and a cylindrical cover 18 is disposed on the outer periphery of the valve presser 14 above the housing 10. In the present embodiment, the housing 10, the valve retainer 14, and the cover 18 constitute a faucet body.

  Further, the hot and cold water mixing faucet 100 has a rotating cap 8 as temperature adjusting means rotatably attached to the upper part of the valve presser 14 and a shaft 120 attached to the adjusting rod 12 a of the hot and cold water mixing valve unit 12. And a flow rate adjusting lever 106 attached to the tip of the shaft 120, and a guide portion 22 attached around the adjusting rod 12a. In the present embodiment, the adjustment rod 12 a and the guide part 22 constitute an adjustment part of the hot and cold mixing valve unit 12.

  In the present embodiment, the flow rate adjusting means is configured as a flow rate adjusting lever 106 that extends linearly in a substantially radial direction of a circle centered on the second axis H. In the present embodiment, the flow rate adjusting lever 106 is composed of a rod-like member having a thin circular cross section, and it is difficult to rotate the adjusting rod 12a around the first axis by holding the lever. is there. Further, in the present embodiment, even when the flow rate adjusting lever 106 is most inclined, the tip when the flow rate adjusting lever 106 is projected in the first axis V direction is the rotating portion of the rotating cap 8. It is comprised so that it may be located inside the circle of 8b. Therefore, the longest distance D2 from the protruding end 106a of the flow rate adjusting lever 106 to the first axis V is shorter than the longest distance D1 from the protruding end of the temperature adjusting lever 8a that is the temperature adjusting operation unit to the first axis V. It is comprised so that it may become.

  Therefore, when the user grips the temperature adjustment lever 8a, a large torque around the first axis V can be easily applied to the adjustment rod 12a. When the flow rate adjusting lever 106 is gripped, it is difficult to apply a large torque to the adjusting rod 12a. Thereby, it is possible to prevent the adjustment rod 12a from being accidentally rotated around the first axis V by the operation of the flow rate adjustment lever 106.

  According to the hot and cold water mixing faucet of the second embodiment of the present invention, since the flow rate adjusting lever extends in a substantially radial direction of a circle centering on the second axis, by gripping and operating the flow rate adjusting lever, It becomes difficult to rotate the adjustment rod about the first axis. Accordingly, it is possible to prevent the adjustment rod from being accidentally rotated about the first axis by gripping and operating the flow rate adjustment lever.
