By the turning operation of the turning handle 60, the cylinder 72 of the flow rate adjusting valve 70 is turned relative to the holder 71, and hot water in an amount corresponding to the turning amount is discharged from the hot water discharge port 40.

The rotary handle 60 is brought into a locked state in which the rotary operation, which is a water discharge operation, is locked by the lock mechanism. This locked state is switched to the unlocked state by performing the unlocking operation. In the first embodiment, the rotatable handle 60 is provided so as to be movable also in the central axis C direction. The unlocking operation described above is a moving operation of the rotary handle 60 in the direction of the central axis C. Specifically, the unlocking operation is a pulling operation in the central axis C direction of the rotatable handle 60 in the locked state.

The structure of the rotatable handle 60 will be described below. As shown in FIGS. 5 to 7, the rotatable handle 60 has a handle body 61, a handle side shaft member 62, a handle side lock member 63, and a lid member 64. The handle body 61 has a columnar shape having a diameter substantially the same as the outer diameter of the discharge pipe 20, and its central axis is coaxial with the central axis C of the linear portion 21 of the discharge pipe 20 and is located at the tip of the discharge pipe 20. It is arranged. A reduced diameter portion 61A is formed on the base end side of the handle body 61. The diameter-reduced portion 61A is formed so as to have a diameter smaller than that of the other portion of the outer peripheral surface of the handle body 61, and is inserted into the gap S1 between the valve case 23B and the cover member 24 described above. The outer peripheral surface of the reduced diameter portion 61A is colored red.

A recess 61B is formed at the end of the handle body 61 on the side of the reduced diameter portion 61A. The recess 61B is formed by being depressed from one end of the handle body 61 in the central axis direction. Further, the handle body 61 is provided with a through hole 61C and a groove portion 61D. The through hole 61C is formed along the central axis of the handle body 61 so as to penetrate from the bottom surface of the recess 61B to the end surface on the tip side. The groove portion 61D is formed as a substantially L-shaped groove that extends in the outer peripheral direction from the center of the end surface on the tip end side of the handle body 61 having a cylindrical shape and extends along the central axis on the outer peripheral surface. A lid member 64 is attached to the groove 61D. Further, the handle body 61 is provided with display portions 81 and 82 described later.

The handle side shaft member 62 has a cylindrical shape with a step formed on the outer peripheral surface. In the handle side shaft member 62, the inner peripheral surface of one end portion (large diameter end portion) 62A formed to have a large diameter is engaged with the outer peripheral surface of the operation shaft portion 72B of the cylinder 72. From the other end portion (small-diameter end portion) 62B formed to have a small diameter of the handle-side shaft member 62, a screw that is screwed into the operation shaft portion 72B is inserted. Thereby, the handle side shaft member 62 is fixed to the operation shaft portion 72B. Further, as shown in FIGS. 6 and 7, the handle-side shaft member 62 is provided on the outer peripheral surface thereof with a pair of convex portions 62C that project outward and extend along the axial direction. The pair of convex portions 62C are provided at equal intervals in the circumferential direction of the outer peripheral surface of the large-diameter end portion 62A, and in the state where the handle side shaft member 62 is fixed to the operating shaft portion 72B, the above-mentioned operating shaft portion is provided. The outer peripheral surface of 72B and the inner peripheral surface of the lock member 73 are respectively fitted in the gaps S2. The handle side shaft member 62 is rotatably provided in an arcuate gap S2 between the pair of protrusions 73A of the lock member 73 within a range (about 90°) in which the convex portion 62C can move.

As shown in FIGS. 5 and 7, the handle side lock member 63 is formed into a cylindrical shape whose inner peripheral surface engages with the outer peripheral surface of the large diameter end portion 62A of the handle side shaft member 62. The handle-side lock member 63 has a flange portion 63A, a cutout portion 63B, and a protruding portion 63C. The flange portion 63A closes an opening at one end of the handle side lock member 63 having a cylindrical shape. The handle side lock member 63 is fixed to the handle body 61 with a screw so that the flange portion 63A abuts the bottom surface of the recess 61B of the handle body 61.

The notch portion 63B is formed by notching the peripheral wall of the handle side lock member 63 in the axial direction. The cutout portions 63B are formed in a pair at equal intervals in the circumferential direction. A pair of convex portions 62C of the handle side shaft member 62 are engaged with the pair of notches 63B, respectively. As a result, the handle-side lock member 63 is movable in the axial direction of the handle-side shaft member 62, which is the extending direction of the convex portion 62C, and when the handle main body 61 is rotated, the edge of the cutout portion 63B. Contacts the convex portion 62C to rotate the handle-side shaft member 62. That is, when the handle main body 61 is moved along the axial direction, the handle side lock member 63 is moved relative to the handle side axial member 62 in the axial direction, and the handle main body 61 is rotated about the rotation axis. , Is rotated together with the handle side shaft member 62.

The protruding portion 63C is formed so as to protrude in the axial direction from the end portion of the handle side lock member 63 on the side opposite to the flange portion 63A. As shown in FIG. 7, the projecting portion 63C projects in an arc shape following the peripheral wall of the handle side locking member 63. A pair of protrusions 63C are provided at equal intervals in the circumferential direction. The pair of projecting portions 63C can be inserted into and removed from the above-described gap S2. Specifically, as shown in FIG. 6, the pair of protrusions 63C fills the gap S2 in the arc-shaped gap S2 where the convex portion 62C of the handle side shaft member 62 is not inserted. Inserted in. As a result, the movement of the convex portion 62C within the gap S2 is restricted, and the handle-side shaft member 62 becomes unrotatable. That is, the rotary handle 60 locks the rotary operation, which is a water discharge operation, in a state where the protrusion 63C of the handle-side lock member 63 is inserted into the gap S2 between the lock member 73 and the handle-side shaft member 62. It is locked. In this embodiment, the lock mechanism according to the present invention is realized by such a configuration.

Further, the above-mentioned locked state is released by removing the protruding portion 63C from the gap S2. Specifically, when the rotatable handle 60 (handle body 61) is pulled and moved in the axial direction, the handle-side lock member 63 also moves in the axial direction and the protrusion 63C comes out of the gap S2. As a result, the lock release state is reached in which the rotary handle 60 can be rotated.

The rotatable handle 60 has a spring 65 as shown in FIG. The spring 65 applies an urging force to the rotary handle 60 in a locked state when the rotary handle 60 is not operated. Therefore, the pulling operation of the rotary handle 60 is performed against the biasing force of the spring 65. As shown in FIG. 5, the spring 65 is disposed between the handle side lock member 63 and the screw SC (washer W) that fixes the handle side lock member 63 to the operation shaft portion 72B.

The lid member 64 is formed in an L shape, and is detachably fitted into the groove portion 61D of the handle body 61. The lid member 64 closes the through hole 61C of the handle body 61. Further, the lid member 64 is colored in a red color different from the surrounding color (white), and is a guide for the amount of rotation of the rotary handle 60 and that the rotary handle 60 is a hot water operation handle. It functions as a mark for arousal.

The display unit 81 shows the water discharge operation by the rotary handle 60 as the operation unit. In the case of the present embodiment, the display section 81 displays the characters “hot water comes out”, which represents the action of the operation, and the arrow figure, which represents the operation direction. The display unit 81 appears in the unlocked state in which the turning operation as the water discharge operation can be performed by the turning handle 60 that is the operation unit. Specifically, as shown in FIG. 4, the display portion 81 is provided on the reduced diameter portion 61A of the handle body 61, and is pulled by the pulling operation of the rotatable handle 60 which is an operation for releasing the lock state. Appear. The display unit 81 is covered by the cover member 24 in the locked state in which the rotation operation is locked. Further, the display portion 81 is shown by white characters and figures on the outer peripheral surface of the reduced diameter portion 61A colored in red.

The display section 82 shows a lock release operation for switching the rotation operation of the rotary handle 60 from the locked state to the unlocked state. In the case of the present embodiment, the display unit 82 displays the characters “pull” indicating the operation method and the arrow figure indicating the operation direction. The display unit 82 shows these characters and figures in the locked state. As shown in FIG. 4, the display unit 82 is provided on the outer peripheral surface which is the operation surface of the handle body 61. The display unit 82 is shown in red letters and figures on a white background.

Next, the operation of the water faucet 1 of the first embodiment configured as described above will be described.
In the faucet 1, the lever-type handle 50 is operated when performing a water discharge operation for discharging hot water, and the rotary handle 60 is operated when performing a water discharge operation for discharging hot water. Of these two handles 50 and 60, the rotatable handle 60 has a lid member 64 colored red. Therefore, it is easily recognized that the rotatable handle 60 is a handle for discharging hot water. Further, in the case of the present embodiment, since the lid member 64 of the rotary handle 60 is made red, which is different from the white of the other parts, it is easily noticeable and easily caught by the operator. In addition, since it is red, it also calls attention to handling hot water.

In the normal state, the rotary handle 60 is in a locked state in which the rotary operation is locked. Therefore, the hot water is prevented from being discharged due to an unintended operation or an erroneous operation. Further, in the locked state, the display of the display unit 81 indicating the rotation operation which is the ejection operation is not displayed. Therefore, it is possible to suppress an undesired turning operation in the locked state.

In order to perform the rotation operation which is the water discharge operation by the rotation type handle 60, first, the lock release operation is performed to bring the lock release state. Specifically, a pulling operation of pulling the rotatable handle 60 in the distal direction along the central axis C of the discharge pipe 20 is performed. As a result, as shown in FIGS. 8 and 9, the rotatable handle 60 moves in the axial direction. Along with this, the protrusion 63C of the handle-side lock member 63 comes out of the gap S2, and the lock is released. When this unlocking operation is performed, the operating method and the operating direction of the unlocking operation are clearly shown by the display portion 82 provided on the outer peripheral surface of the handle body 61. Therefore, it is difficult for an erroneous operation other than the operation displayed on the display unit 82 to be performed.

In the unlocked state in this way, the handle body 61 is in a state in which the reduced diameter portion 61A is pulled out from the gap S1. As a result, the display unit 81 appears. By displaying this display unit 81, the operating method and operating direction of the water discharge operation are shown. Therefore, it is difficult to perform an incorrect water discharge operation other than the operation displayed on the display unit 81. Further, the display unit 81 appears in the unlocked state, and does not appear in the locked state. Therefore, the turning operation in the locked state, which is prompted by the display of the display unit 81, is avoided, and it is difficult to perform an unreasonable turning operation. Further, the appearance of the reduced diameter portion 61A colored in red in the unlocked state alerts the user that hot water can be discharged.

When the rotary handle 60 is rotated, hot water is discharged from the hot water discharge port 40, as shown in FIG. The rotatable handle 60 rotates the cylinder 72 of the flow rate adjusting valve 70. Therefore, the hot water discharged from the hot water discharge port 40 is discharged in a discharge amount according to the operation amount of the rotating operation of the rotary handle 60. The flow rate adjusting valve 70 only rotates the cylinder 72 relative to the holder 71 by the rotation of the rotary handle 60, and does not cause axial displacement. For this reason, axial displacement due to the rotation of the rotary handle 60 does not occur, and the appearance is not impaired.

Further, since the rotatable handle 60 is provided at the tip of the discharge pipe 20, it is safe for the operator to perform a rotating operation before the discharged hot water. Further, the rotatable handle 60 is formed in a cylindrical shape having a diameter substantially the same as the outer diameter of the discharge pipe 20, and its central axis is coaxial with the central axis C of the linear portion 21 of the discharge pipe 20. Since it is arranged at the tip of the linear portion 21, it has a neat appearance.

The hot water discharge port 40 is provided closer to the tip of the discharge pipe 20 than the hot water discharge port 30, and the hot water is discharged from a position closer to the rotary handle 60 arranged at the tip of the discharge pipe 20. .. Further, since the lower end portion of the hot water discharge port 40 from which hot water is discharged is colored in red, it can be easily recognized that it is the hot water discharge port, and it is easy for the operator to catch the eye and call attention. .. Furthermore, since the red color at the lower end of the hot water outlet 40 and the red color of the lid member 64 of the rotary handle 60 are the same color, it is easy to recognize the relationship between the hot water outlet 40 and the rotary handle 60. ..

Further, the hot water discharge port 30 and the hot water discharge port 40 are provided separately. Accordingly, for example, even when the hot water is discharged immediately after the hot water is discharged, the remaining hot water does not unexpectedly discharge. Further, since the lower end of the hot water discharge port 30 is located above the lower end of the hot water discharge port 40, the difference in the discharge position from the hot water discharge port 40 from which the hot water is discharged can be easily recognized.

As described above, the water faucet 1 of the present embodiment is in the locked state in which the rotary handle 60 as an operation unit for performing the rotary operation that is the water discharge operation and the rotary operation by the rotary handle 60 are locked. And a display section 81 that appears in the unlocked state in which the turning operation by the turning handle 60 is possible and indicates the turning operation.

As described above, the water faucet 1 is locked by the lock mechanism against the water discharge operation by the rotary handle 60, and when the locked state is released, the water discharge operation is performed. The display 81 shown appears. Therefore, in the locked state, unintentional rotation operation is prevented, and in the unlocked state, a display regarding the rotation operation of the display unit 81 is displayed, and the operator is prompted to operate according to the display.

Therefore, the water faucet 1 of the first embodiment can prevent an erroneous operation and allow the operator to recognize a correct water discharge operation.

Further, the water faucet 1 is provided with a display section 82 that shows an unlocking operation for switching from the locked state to the unlocked state in the locked state. Therefore, the display of the display unit 82 allows the user to clearly recognize the unlocking method. Further, the display of the display unit 81 and the display unit 82 allows the operator to recognize the correct operation method and the correct operation procedure.

Further, the rotary handle 60 as an operating portion is provided so as to be rotatable coaxially with the central axis C of the linear portion 21 of the discharge pipe 20 as a predetermined rotational axis, and in the central axis C direction.

The display portion 281 is arranged on the reduced diameter portion 260A of the rotatable handle 260, like the display portion 81 of the first embodiment, but its position is closer to the tip of the reduced diameter portion 260A than the display portion 81 ( The handle main body 261 is located near the base end). On the display unit 281, a character “push” indicating an operation method and an arrow figure indicating an operation direction are displayed. The display unit 282 is arranged at the same position as the display unit 82 of the first embodiment. On the display unit 282, a character “turn” indicating an operation method and an arrow figure indicating an operation direction are displayed. Further, an opening 24A is formed in the cover member 24 of the discharge pipe 20. The opening 24A is formed at a position corresponding to the position where the display unit 281 moves by the rotating operation.
In the second embodiment, the display unit 281 is shown with white characters and figures on a red background, like the display unit 81 of the first embodiment, but the reduced diameter portion 260A is the same white as the surroundings. Further, the display unit 282 is shown in red letters and figures on a white background, like the display unit 82 of the first embodiment.

As shown in FIG. 11, in the locked state of the rotatable handle 260, the display unit 281 is arranged at a position where it cannot be seen, and the display unit 282 is arranged at a position where it can be seen. In this locked state, the pushing operation, which is the discharging operation, is locked. Then, from this state, a rotation operation, which is an unlock operation, is performed in accordance with the display on the display unit 282 to switch to the unlocked state shown in FIG. In the unlocked state, the display unit 281 appears at the position of the opening 24A. That is, the display unit 281 appears in the unlocked state in which the water discharge operation is enabled by performing the rotation operation which is the unlock operation. Then, when the pushing operation which is the water discharge operation is performed according to the display of the display unit 281, the hot water is discharged from the hot water discharge port 40.

As described above, in the water faucet 201 of the second embodiment, the lock mechanism locks the pushing operation, which is the water discharge operation by the rotary handle 260, and the lock state is released, so that the pushing operation that is the water discharge operation is performed. A display unit 281 indicating the operation appears. Therefore, in the locked state, an unintentional turning operation is prevented, and in the unlocked state, a display related to the turning operation of the display unit 281 is displayed to prompt the operator to operate according to the display.

Therefore, the water faucet 201 of the second embodiment can also prevent an erroneous operation and allow the operator to recognize the correct method of the water discharge operation.

In addition, the water faucet 201 includes a display unit 282 that indicates an unlocking operation for switching from the locked state to the unlocked state in the locked state. Therefore, the method of the unlock operation can be clearly recognized by the display on the display unit 282. In addition, each display of the display unit 281 and the display unit 282 allows the operator to recognize a correct operation method and a correct operation procedure.

In addition, the rotary handle 260 as an operation unit is rotatably provided coaxially with the central axis C of the linear portion 21 of the discharge pipe 20 as a predetermined rotary shaft, and in the central axis C direction. The unlocking operation for switching from the locked state to the unlocked state is a rotating operation around the central axis C of the rotary handle 260, and the water discharge operation is for the rotary handle 260. This is a moving operation in the central axis direction. Thus, the water faucet 201 also realizes the unlocking operation and the water discharge operation by a combination of easy operations.
