Description

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

Patent Document 1 discloses a faucet that mixes hot water and cold water and discharges hot water at a desired temperature. In this faucet, when the temperature control handle is rotated without pressing the push button provided on the temperature control handle, the regulating portion of the push button comes into contact with the end of the first wall portion of the non-rotating member. As a result, the rotation of the temperature control handle can be restricted 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 regulating portion of the push button is no longer in contact with the end portion of the first wall portion of the non-rotating member. As a result, it is possible to permit the rotation of the temperature control handle in the direction in which hot water with a higher temperature is discharged.

JP 2018-135731 A

However, in the case of adopting the structure of Patent Document 1, when force is applied to the temperature control handle in a direction to rotate the temperature control handle without pressing the push button, the restriction portion of the push button is moved to the first wall of the non-rotating member. While in contact with the end of the part, it tilts within the range of rattling in the area where it is placed. Then, the regulating portion of the push button is also inclined 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 regulating portion of the push button from the end portion of the first wall portion of the non-rotating member in the direction in which the push button moves.
When reducing the outer diameter of the temperature control handle while adopting the structure of Patent Document 1, the radial thickness of the temperature control handle of each of the regulating portion of the push button and the first wall portion of the non-rotating member is reduced. will do. In this case, when force is applied to the temperature control handle in a direction to rotate the temperature control handle without pressing the push button, the pressure is applied from the end of the first wall portion of the non-rotating member applied to the regulating portion of the push button. Due to the force in the direction in which the button moves, the regulating portion tends to come into a state where it does not come into contact with the end of the first wall portion, and hot water with a higher temperature is discharged from the temperature control handle even though the push button is not pressed. There is a risk that it will rotate in the direction

As shown in FIG. 6, four groove portions 52C and a rotation restricting groove portion 52D, which is a locked portion and a constituent element of the operation portion for water supply device, are formed at the end portion of the opening side of the space 52A of the case 52, as shown in FIG. It is The rotation restricting groove portion 52D is provided in the operation member 50. As shown in FIG. The four groove portions 52C and the rotation restricting groove portion 52D are recessed 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 in the direction away from the central axis of the space 52A. Each groove portion 52C corresponds to each protrusion portion 35B of the switching portion main body 35, and is arranged side by side in the circumferential direction of the inner peripheral surface 52E. Each groove portion 52C has a first groove portion 52F extending in the central axis direction of the space 52A and a clockwise direction in the circumferential direction of the inner peripheral surface 52E from the end of the first groove portion 52F away from the opening in a plan view seen from above.

The rotation restricting groove portion 52D has a fourth side surface 52H, a fifth side surface 52J, and a contacted 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 arcuately along the inner peripheral surface 52E and is further away from the central axis of the space 52A than the inner peripheral surface 52E. The fifth side surface 52J continues to the left edge of the fourth side surface 52H, extends toward the central axis of the space 52A, and continues to the inner peripheral surface 52E. The contacted surface 52K continues to the right edge of the fourth side surface 52H and extends toward the central axis of the space 52A. The angle θ4 formed by the contact surface 52K and the right end portion of the fourth side surface 52H in plan view from above is smaller than 90° (that is, an acute angle). Also, the angle θ4 is larger than the angle θ3 (see FIG. 7A). An inclined surface 52L is formed in the first groove portion 52F adjacent to the right side of the rotation restricting groove portion 52D. In the first groove portion 52F adjacent to the right side of the rotation restricting groove portion 52D, the inclined surface 52L is formed by a surface (hereinafter also referred to as a bottom surface 52M) that 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 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 portions 52F of the groove portions 52C of the case 52 are aligned with the positions of the projecting portions 35B of the switching portion main body 35 . Then, the opening of the space 52A of the operation member 50 is brought close to the water supply device main body 30, and the first grooves 52F are fitted to the projections 35B. At this time, as shown in FIG. 7A, the corner C1 (hereinafter also referred to as the corner C1) where the second side surface 37E and the first side surface 37D of the locking portion main body 37C of the locking portion 37 are connected is inclined. It is arranged near the position where the surface 52L and the bottom surface 52M are continuous.

Then, when each protruding portion 35B reaches a position where each first groove portion 52F and each second groove portion 52N are continuous, the operation member 50 is moved to the center of the space 52A with respect to the water supply device main body 30 in plan view from above. Operate to rotate counterclockwise around the axis. Then, each projecting portion 35B of the switching portion main body 35 is fitted into each second groove portion 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 C<b>1 slides on the inclined surface 52</b>L, the locking portion 37 moves toward 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 greater than 90° (that is, an obtuse angle). As a result, the locking portion main body 37C can slide smoothly while contacting the inclined surface 52L.

When the operation member 50 is further rotated counterclockwise around the central axis of the space 52A, the first side surface 37D of the locking portion main body 37C is moved between 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 abutted surface 52K of the rotation restricting groove portion 52D (see FIG. 7(C)). At this time, the engaging portion 37 is in a permitting state (hereinafter also referred to as permitting state) in which the operation member 50 is permitted to rotate clockwise about the center axis of the space 52A.
Then, when the corner portion C2 (hereinafter also referred to as the corner portion C2) where 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 The biasing force of the spring 39 moves the locking portion 37 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 engaging portion 37 is engaged with the rotation restricting groove portion 52G to enter a restricting state (hereinafter also referred to as restricting state) in which clockwise movement of the operating member 50 around the central axis of the space 52A is restricted. . 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 apparatus main body 30 without pressing the button 37B of the locking portion 37 to operate. In other words, since it is not necessary to press the button 37B of the engaging portion 37 to operate, the operation member 50 can be easily attached to the water supply device main body 30 .

In a state in which the operation member 50 is attached to the water supply device main body 30, the operation member 50 is placed in the space 52A in plan view from above without pressing the button 37B of the locking portion 37 (that is, in the restricted state). A case where it is operated to rotate clockwise around the central axis of is described.
In this case, the corner portion C2 abuts on the abutted surface 52K of the rotation restricting groove portion 52G. When the operation member 50 is further rotated clockwise about the central axis of the space 52A, the engaging portion 37 tilts within the range of rattling in the area where it is arranged, and contacts the contact surface 37G. The abutted surface 52K of the rotation restricting groove portion 52G abuts (see FIG. 8).

As shown in FIG. 8, the abutment surface 37G and the abutted surface 52K are arranged such that the abutted surface 52K of the rotation restriction groove portion 52G abuts against the abutment surface 37G in the restricted state. As the button 37B moves toward the release direction R1 (hereinafter also referred to as the release direction R1) in which the button 37B moves from the restricted state to the allowable state with respect to the moving direction D1 (hereinafter also referred to as the moving direction D1), the moving direction changes. It is slanted towards D1. Further, the contact surface 37G of the locking portion 37 provided with the button 37B is directed in the moving direction D1 as it goes in the releasing direction R1 from the contacted surface 52K of the rotation restricting groove portion 52G in which the button is not provided. 7(D)).
At this time, a force F is applied from the locking portion main body 37C to the contacted surface 52K of the rotation restricting groove portion 52G in the direction along the inner peripheral surface 52E of the locking portion main body 37C. The force F is divided into forces Fv and Fp in a direction perpendicular to the contacted surface 52K of the rotation restricting groove portion 52G and in a direction along the contacted surface 52K, respectively. The force Fv is canceled out by the reaction force Fr generated from the contacted surface 52K of the rotation restricting groove portion 52G to the contact surface 37G. The force Fp is applied in a direction to move the locking portion main body 37C 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 opposite to the release direction R1). acts on the locking portion main body 37C. As a result, the abutting surface 37G of the locking portion main body 37C is less likely to come off the abutted surface 52K of the rotation restricting groove portion 52G. That is, when the rotation restricting groove portion 52G is engaged with the engaging portion 37, the engaging portion 37 moves in the direction in which the button 37B moves (that is, the central axis of the switching portion main body 35) to change from the restricted state to the permitted state. ), which is the release direction R1. Therefore, even if the operation member 50 is operated without operating the button 37B of the locking portion 37, the water supply device operation portion can better restrict the rotation of the operation member 50 with respect to the water supply device main body 30. can do.

When the operation member 50 is removed from the water supply device main body 30, the operation member 50 is rotated clockwise around the central axis of the space 52A in plan view from above while pressing the button 37B of the locking portion 37. . When the button 37B is pressed, the locking portion 37 also moves toward the central axis of the switching portion main body 35 . Then, the corner C2 is closer to the central axis of the space 52A than the inner peripheral surface 52E. At this time, the abutment surface 37G of the locking portion 37 and the abutted surface 52K of the rotation restricting groove portion 52D do not engage with each other, allowing the operation member 50 to move clockwise around the central axis of the space 52A. Allowable state. In other words, the button 37B moves the engaging portion 37 from the restricting state to the permitting 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 releasing direction R1. As a result, in plan view from above, the operation member 50 is rotated clockwise around the center axis of the space 52A, and each projecting portion 35B is removed from each second groove portion 52N. Thus, the operating member 50 can be removed from the water supply device body 30 .

In this manner, when the operation portion for the water supply device is in the restricted state, the rotation restriction 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 restricted state to the permitted state. Become. Therefore, even if the operation member 50 is operated while the button 37B is not operated, the water supply device operation portion can reliably restrict the movement of the operation member 50 in the restricted state.

Therefore, it is possible to reliably prevent erroneous operation of the operation unit for the water supply device.

The button 37B of the operation portion for the water supply device is provided on the locking portion 37, and the locking portion 37 has a contact surface 37G against which the rotation control groove portion 52G contacts in the restricted state. , the operation member 50 is tilted toward the movement direction D1 toward the release direction R1 with respect to the movement direction D1 in which the operation member 50 moves so that the rotation regulation groove portion 52G contacts the contact surface 37G in the regulation state. there is Therefore, when the operating member 50 is operated in the restricted state and the abutted surface 52K of the rotation restricting groove portion 52G contacts the abutment surface 37G, the rotation restricting groove portion 52G moves in the direction opposite to the releasing direction R1. A force containing the component will be applied. Due to this force, the abutted surface 52K of the rotation restricting groove portion 52G, which is in contact with the abutting surface 37G of the engaging portion 37, is less likely to come off from the abutting surface 37G of the engaging portion 37. Movement of the operating member 50 in the restricted state can be more reliably restricted.

The rotation restriction groove portion 52G of the operation portion for the water supply device has a contact surface 52K that contacts the contact surface 37G in the restricted state, and the contact surface 52K extends in the release direction with respect to the moving direction D1. The contact surface 37G of the locking portion 37 is tilted in the movement direction D1 as it moves toward R1, and the contact surface 37G of the locking portion 37 moves in the release direction R1 from the contact surface 52K of the rotation restricting groove portion 52G. steeply sloping towards
Therefore, even if the engaging portion 37 provided with the button 37B tilts within the rattling range in the region where the water supply device operation portion is arranged, the operation portion contacts the contact surface 52K. It is possible to avoid point contact with the surface 37G and allow surface contact. As a result, the water supply device operating portion can easily apply a force including a component in the direction opposite to the releasing direction R1 to the engaging portion 37 provided with the button 37B. The grooves 52G are less likely to come off from each other, and the movement of the operating member 50 in the restricted state can be more reliably restricted.

The plate spring 153 applies a biasing force to the base portion 152A of the locked portion 12 in a direction away from the central axis of the outer cylindrical portion 151A.

A case will be described in which the operating member 150 is rotated to bring the water supply temperature from a state below a predetermined temperature (for example, 40° C.) to a state above the predetermined temperature.
When the water supply temperature is below a predetermined temperature, the sixth side surface 152D of the locked portion 152 is in contact with the first inner peripheral surface 134A of the cylindrical portion 134 of the water supply unit 132, as shown in FIG. 14(A). It is in contact.

Then, in a side view from the left, the operating member 150 is rotated counterclockwise around the central axis of the outer cylindrical portion 151A without pressing the button 152B of the locked portion 152. As shown in FIG. Then, a corner portion C3 where the contact surface 152E of the locked portion 152 and the sixth side surface 152D are continuous (hereinafter also referred to as the corner portion C3) contacts the contact surface 134B of the cylindrical portion 134 of the water supply unit 132. (See FIG. 14(B).).
Further, when the operating member 150 is operated to rotate counterclockwise around the central axis of the outer cylindrical portion 151A, the engaged portion 152 tilts within the range of rattling in the area where it is arranged, and abuts. The surface 134B and the contacted surface 152E are in contact (not shown).

When the button 152B of the locked portion 152 is pressed while applying a force to the operating member 150 to rotate the outer cylindrical portion 151A counterclockwise, the corner portion C3 or the contacted surface 152E comes into contact. While sliding on the surface 134B, the engaged portion 152 moves toward the central axis of the outer cylindrical portion 151A. As a result, the corner portion C3 moves toward the corner portion C4 (hereinafter also referred to as the corner portion C4) where the contact surface 134B of the cylindrical portion 134 of the water supply unit 132 and the second inner peripheral surface 134C are continuous. When the corner portion C3 reaches the corner portion C4 and the contacted surface 152E and the contact surface 134B are no longer in contact with each other, the operating member 150 further rotates counterclockwise. Then, the sixth side surface 152D of the engaged portion 152 contacts the second inner peripheral surface 134C of the cylindrical portion 134 of the water supply unit 132 and slides on the second inner peripheral surface 134C (see FIG. 14C). ). In this way, the water supply device operation unit can change the water supply temperature from a state below the predetermined temperature to a state above the predetermined temperature.

A case will be described in which the operation member 150 is rotated to change the water supply temperature from a state higher than a predetermined temperature to a state lower than or equal to the predetermined temperature.
When the water supply temperature is equal to or higher than the predetermined temperature, the sixth side surface 152D of the locked portion 152 is in contact with the second inner peripheral surface 134C of the cylindrical portion 134 of the water supply unit 132. As shown in FIG. Then, in a side view from the left side, the operation member 150 is rotated clockwise around the central axis of the outer cylindrical portion 151A without pressing the button 152B of the locked portion 152 . Then, the sixth side surface 152</b>D of the locked portion 152 slides on the second inner peripheral surface 134</b>C of the cylindrical portion 134 of the water supply unit 132 . Then, when the corner portion C3 reaches the corner portion C4, the engaged portion 152 moves away from the central axis of the outer cylindrical portion 151A by the biasing force of the leaf spring 153. As shown in FIG. Thus, the sixth side surface 152D of the engaged portion 152 contacts the first inner peripheral surface 134A of the cylindrical portion 134 of the water supply unit 132. As shown in FIG. As a result, the operating member 150 can be further rotated clockwise. In this way, the water supply device operation unit can bring the water supply temperature from a state higher than the predetermined temperature to a state lower than the predetermined temperature.

In this manner, when the water supply device operating portion is in the restricted state, the locked portion 152 is locked to the cylindrical portion 134, so that the locked portion 152 is less likely to move in the direction from the restricted state to the permitted state. Become. Therefore, even if the operation member 150 is operated while the button 152B is not operated, the water supply device operation portion can reliably restrict the movement of the operation member 150 in the restricted state.

Therefore, it is possible to reliably prevent erroneous operation of the operation unit for the water supply device.

The button 152B of the operation portion for the water supply device is provided on the locked portion 152, and the cylindrical portion 134 has a contact surface 134B with which the locked portion 152 contacts in the restricted state. With respect to the moving direction D2 in which the operating member 150 moves so that the engaged portion 152 abuts against the contact surface 134B in the restricted state, the operating member 150 is inclined in the direction opposite to the moving direction D2 as it goes toward the releasing direction R2. are doing.
Therefore, when the operating member 150 is operated in the regulated state and the locked portion 152 contacts the contact surface 134B, a force including a component in the direction opposite to the releasing direction R2 is applied to the locked portion 152. will be This force makes it difficult for the contacted surface 152E of the engaged portion 152, which is in contact with the contact surface 134B, to come off the contact surface 134B of the cylindrical portion 134, so that the operation member 150 is in the regulated state. movement can be regulated more reliably.

The locked portion 152 of the operation portion for water supply device has a contact surface 152E that contacts the contact surface 134B in the regulated state, and the contact surface 152E extends in the release direction with respect to the moving direction D2. The contact surface 152E of the locked portion 152 moves toward the release direction R2 from the contact surface 134B of the cylindrical portion 134. It slopes steeply in the direction opposite to direction D2.
Therefore, even if the engaged portion 152 provided with the button 152B tilts within the rattling range in the region where the water supply device operating portion is arranged, the operated portion contacts the contacted surface 152E. Point contact with the contact surface 134B can be avoided, and surface contact can be achieved. As a result, the water supplying apparatus operating portion can easily apply a force including a component in the direction opposite to the releasing direction R2 to the engaged portion 152 provided with the button 152B. The portions 152 are less likely to come off from each other, and the movement of the operating member 150 in the restricted state can be further reliably restricted.
