Description

The present invention relates to an operation unit for a water supply device.

Patent Document 1 discloses a faucet that mixes hot water and water and discharges hot water at a desired temperature. When the temperature control handle is rotated without pressing the push button provided on the temperature control handle, the control portion of the push button comes into contact with the end of the first wall portion of the non-rotating member. Therefore, the rotation of the temperature control handle can be regulated so that the temperature of the discharged hot water does not exceed a predetermined temperature. Then, when the push button of the temperature control handle is pushed, the regulation portion of the push button does not come into contact with the end portion of the first wall portion of the non-rotating member. As a result, it is possible to allow the temperature control handle to rotate in the direction in which hot water having a higher temperature is discharged.

JP-A-2018-135731

However, when the structure of Patent Document 1 is adopted, if a force is applied to the temperature control handle in the direction of rotating the temperature control handle without pressing the push button, the regulation portion of the push button becomes the first wall of the non-rotating member. It tilts within the range of rattling in the area where it is placed while in contact with the end of the portion. Then, the regulation portion of the push button also tilts with respect to the end portion of the first wall portion of the non-rotating member. As a result, a force is applied to the restricting portion of the push button in the direction in which the push button moves from the end of the first wall portion of the non-rotating member.
When the outer diameter of the temperature control handle is reduced while adopting the structure of Patent Document 1, the radial thickness of the temperature control handle of the control portion of the push button and the first wall portion of the non-rotating member is reduced. Will be done. In this case, if a force is applied to the temperature control handle in the direction of rotating the temperature control handle without pressing the push button, the push button is pushed from the end of the first wall portion of the non-rotating member applied to the regulation portion. Due to the force in the direction in which the button moves, the regulating part tends to be in a state where it does not come into contact with the end of the first wall part, and even though the push button is not pressed, hot water at a higher temperature is discharged from the temperature control handle. There is a risk of rotation in the direction of

As shown in FIG. 6, four groove portions 52C and a rotation restricting groove portion 52D which is a locked portion and a component of the operation portion for the water supply device are formed at the end of the space 52A of the case 52 on the opening side. Has been done. The rotation restricting groove 52D is provided in the operating member 50. The four groove portions 52C and the rotation restricting groove portion 52D are formed so as to be recessed in a direction away from the central axis of the space 52A from the inner peripheral surface 52E (hereinafter, also referred to as the inner peripheral surface 52E) of the upper end portion of the space 52A. The groove portions 52C correspond to the protrusions 35B of the switching portion main body 35, and are arranged side by side in the circumferential direction of the inner peripheral surface 52E. Each groove 52C has a first groove 52F extending in the central axis direction of the space 52A, and in a plan view from above, clockwise from the end of the first groove 52F away from the opening in the circumferential direction of the inner peripheral surface 52E. It is provided with a second groove portion 52N that extends.

The rotation restricting groove portion 52D corresponds to the locking portion main body 37C of the locking portion 37. The rotation restricting groove portion 52D includes a fourth side surface 52H, a fifth side surface 52J, and a contact surface 52K. The fourth side surface 52H, the fifth side surface 52J, and the contacted surface 52K extend parallel to the central axis of the space 52A. The fourth side surface 52H extends in an arc along the inner peripheral surface 52E, and is farther from the central axis of the space 52A than the inner peripheral surface 52E. The fifth side surface 52J is continuous with the left end edge of the fourth side surface 52H, extends toward the central axis of the space 52A, and is continuous with the inner peripheral surface 52E. The contacted surface 52K is continuous with the right end edge of the fourth side surface 52H and extends toward the central axis of the space 52A. The angle θ4 formed by the contacted surface 52K and the right end of the fourth side surface 52H in a plan view viewed from above is smaller than 90 ° (that is, an acute angle). Further, the angle θ4 is larger than the angle θ3 (see FIG. 7A). An inclined surface 52L is formed on the first groove 52F adjacent to the right side of the rotation regulation groove 52D. The inclined surface 52L is a surface (hereinafter, also referred to as a bottom surface 52M) of the first groove portion 52F adjacent to the right side of the rotation restricting groove portion 52D, which is farther from the central axis of the space 52A than the inner peripheral surface 52E, and the rotation restricting groove portion. It is continuous with the inner peripheral surface 52E located between the 52D and the first groove portion 52F.

A case where the operation member 50 is attached to the water supply device main body 30 will be described.
First, the first groove 52F of each groove 52C of the case 52 is aligned with the position of each protrusion 35B of the switching portion main body 35. Then, the opening of the space 52A of the operating member 50 is brought close to the water supply device main body 30, and each first groove portion 52F is fitted into each protruding portion 35B. At this time, as shown in FIG. 7A, the corner portion C1 (hereinafter, also referred to as the corner portion C1) in which the second side surface 37E and the first side surface 37D of the locking portion main body 37C of the locking portion 37 are continuous is inclined. The surface 52L and the bottom surface 52M are arranged in the vicinity of continuous positions.

Then, when each of the protruding portions 35B reaches a position where each of the first groove portions 52F and each of the second groove portions 52N are continuous, the operating member 50 is centered on the space 52A with respect to the water supply device main body 30 in a plan view viewed from above. Operate to rotate counterclockwise around the axis. Then, each of the protruding portions 35B of the switching portion main body 35 fits into each of the second groove portions 52N. At this time, the corner portion C1 slides on the inclined surface 52L and moves toward the inner peripheral surface 52E between the rotation restricting groove portion 52D and the first groove portion 52F (see FIG. 7B). When the corner portion C1 slides on the inclined surface 52L, the locking portion 37 moves in a direction approaching the central axis of the switching portion main body 35. Here, the angle θ1 formed by the second side surface 37E of the locking portion main body 37C and the left end portion of the first side surface 37D is larger than 90 ° (that is, an obtuse angle). As a result, the locking portion main body 37C can slide smoothly while being in contact with the inclined surface 52L.

Then, when the operating member 50 is further rotated in the counterclockwise direction around the central axis of the space 52A, the first side surface 37D of the locking portion main body 37C becomes the rotation restricting groove portion 52D and the first groove portion 52F. It abuts on the inner peripheral surface 52E between them and slides toward the contacted surface 52K of the rotation restricting groove 52D (see FIG. 7C). At this time, the locking portion 37 is in an allowable state (hereinafter, also referred to as an allowable state) that allows the operation member 50 to rotate clockwise around the central axis of the space 52A.
Then, when the corner portion C2 (hereinafter, also referred to as the corner portion C2) in which the contact surface 37G of the locking portion main body 37C and the first side surface 37D are continuous reaches the contact surface 52K of the rotation restricting groove portion 52G, the plate Due to the urging force of the spring 39, the locking portion 37 moves in the direction in which the first side surface 37D of the locking portion main body 37C approaches the fourth side surface 52H of the rotation restricting groove portion 52D (see FIG. 7D). As a result, the locking portion 37 is locked to the rotation restricting groove portion 52G, and is in a regulated state (hereinafter, also referred to as a regulated state) for restricting the clockwise movement of the space 52A of the operating member 50 around the central axis. .. In this way, the operating member 50 can be attached to the water supply device main body 30.
The inclined surface 52L formed on the operating member 50 allows the operating member 50 to be attached to the water supply device main body 30 without pressing the button 37B of the locking portion 37 for operation. That is, since it is not necessary to press the button 37B of the locking portion 37 to operate the operating member 50, the operating member 50 can be easily attached to the water supply device main body 30.

In a state where the operating member 50 is attached to the water supply device main body 30, the operating member 50 is placed in the space 52A in a plan view viewed from above without pressing the button 37B of the locking portion 37 (that is, in the regulated state). The case where the operation is performed so as to rotate clockwise around the central axis of the above will be described.
In this case, the corner portion C2 comes into contact with the contacted surface 52K of the rotation restricting groove portion 52G. Then, when the operating member 50 is further operated so as to rotate clockwise around the central axis of the space 52A, the locking portion 37 tilts within the range of rattling in the region where it is arranged, and becomes the contact surface 37G. The contact surface 52K of the rotation restricting groove 52G comes into contact with the contact surface 52K (see FIG. 8).

As shown in FIG. 8, the contact surface 37G and the contact surface 52K have the operating member 50 so that the contact surface 52K of the rotation restricting groove 52G abuts on the contact surface 37G in the regulated state. With respect to the moving direction D1 (hereinafter, also referred to as the moving direction D1), the moving direction is directed toward the release direction R1 (hereinafter, also referred to as the release direction R1) in which the button 37B moves in order to change from the regulated state to the allowable state. It is tilted toward D1. Further, the contact surface 37G of the locking portion 37 provided with the button 37B is directed toward the moving direction D1 from the contacted surface 52K of the rotation restricting groove portion 52G not provided with the button toward the release direction R1. It is steeply inclined (see FIG. 7 (D)).
At this time, a force F is applied to the locking portion main body 37C from the locking portion main body 37C in the direction along the inner peripheral surface 52E toward the contacted surface 52K of the rotation restricting groove portion 52G. The force F is divided as a force Fv and a force Fp in the direction perpendicular to the contacted surface 52K of the rotation restricting groove 52G and in the direction along the contacted surface 52K, respectively. The force Fv is offset by the reaction force Fr generated from the contacted surface 52K of the rotation restricting groove 52G with respect to the contact surface 37G. Then, the force Fp is a direction in which the locking portion main body 37C is moved toward the fourth side surface 52H of the rotation restricting groove portion 52G (that is, a direction away from the central axis of the switching portion main body 35 and a direction opposite to the release direction R1). Acts on the locking portion body 37C. As a result, the contact surface 37G of the locking portion main body 37C is less likely to come off from the contact surface 52K of the rotation restricting groove portion 52G. That is, when the rotation restricting groove portion 52G is locked to the locking portion 37, the locking portion 37 moves in the direction in which the button 37B moves in order to change from the regulated state to the allowable state (that is, the central axis of the switching portion main body 35). It becomes difficult to move in the release direction R1 which is the direction toward. Therefore, even if the operation member 50 is operated without operating the button 37B of the locking portion 37, the operation unit for the water supply device better regulates the rotation of the operation member 50 with respect to the water supply device main body 30. can do.

When removing the operating member 50 from the water supply device main body 30, while pressing the button 37B of the locking portion 37, the operating member 50 is rotated clockwise around the central axis of the space 52A in a plan view viewed from above. .. When the button 37B is pressed, the locking portion 37 also moves in a direction approaching the central axis of the switching portion main body 35. Then, the corner portion C2 approaches the central axis of the space 52A rather than the inner peripheral surface 52E. At this time, the contact surface 37G of the locking portion 37 and the contacted surface 52K of the rotation restricting groove 52D are not locked to each other, and the space 52A of the operating member 50 is allowed to move clockwise around the central axis. It is in an acceptable state. That is, the button 37B moves the locking portion 37 from the regulated state to the allowable state. At this time, the direction in which the locking portion 37 moves (that is, the direction toward the central axis of the switching portion main body 35) is the release direction R1. As a result, in the plan view seen from above, the operating member 50 is rotated clockwise around the central axis of the space 52A, and the protruding portions 35B are disengaged from the second groove portions 52N. In this way, the operating member 50 can be removed from the water supply device main body 30.

As described above, in the regulated state of the water supply device operation unit, the rotation restricting groove portion 52G is locked to the locking portion 37, so that the locking portion 37 is difficult to move in the direction from the regulated state to the allowable state. Become. Therefore, the operation unit for the water supply device can reliably regulate the movement of the operation member 50 in the regulated state even if the operation member 50 is operated when the button 37B is not operated.

Therefore, the operation unit for the water supply device can surely prevent erroneous operation.

The button 37B of the operation unit for the water supply device is provided in the locking portion 37, and the locking portion 37 has an abutting surface 37G to which the rotation restricting groove portion 52G abuts in the restricted state, and the abutting surface 37G With respect to the moving direction D1 in which the operating member 50 moves so that the rotation restricting groove 52G abuts on the contact surface 37G in the regulated state, the operating member 50 is inclined toward the moving direction D1 in the direction of the release direction R1. There is. Therefore, when the operating member 50 is operated in the restricted state and the contacted surface 52K of the rotation restricting groove 52G abuts on the contact surface 37G, the rotation restricting groove 52G is in the direction opposite to the release direction R1. The power containing the components will be given. Due to this force, in the operation unit for the water supply device, the contacted surface 52K of the rotation restricting groove 52G that is in contact with the contact surface 37G of the locking portion 37 is less likely to come off from the contact surface 37G of the locking portion 37. The movement of the operating member 50 in the regulated state can be more reliably regulated.

The rotation restricting groove 52G of the operation portion for the water supply device has a contact surface 52K that abuts on the contact surface 37G in the regulated state, and the contact surface 52K has a release direction with respect to the moving direction D1. It is inclined toward the moving direction D1 toward R1, and the contact surface 37G of the locking portion 37 moves from the contacted surface 52K of the rotation restricting groove 52G toward the release direction R1. It slopes steeply toward.
Therefore, the operation unit for the water supply device comes into contact with the contacted surface 52K even when the locking portion 37 provided with the button 37B is tilted within the range of rattling in the area where the water supply device is arranged. It is possible to avoid contact with the surface 37G at a point and to make contact with the surface. As a result, the operation unit for the water supply device can easily apply a force containing a component in the opposite direction of the release direction R1 to the locking portion 37 provided with the button 37B, so that the locking portion 37 and the rotation restriction are restricted. The groove 52G and the groove 52G are less likely to come off from each other, and the movement of the operating member 50 in the regulated state can be more reliably regulated.
