[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water stop device for a shower, and more particularly to a water stop device for a shower, which is provided in the vicinity of a shower head that ejects hot water, and can stop the hot water and adjust the supply amount at hand. It is a thing.

[0002]

[Prior Art]

 This type of conventional shower water stop device has not been realized. Generally, when washing hair using a shower, the cock provided at the base end of the shower hose is opened and closed to remove hot water. Water is stopped and supply is adjusted.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned cock is provided at a relatively low position such as the edge of the bathtub, a person using the shower in an upright posture should change his posture such as bending down once. In addition to the need to operate it, the eyes were often closed during hair washing to avoid the irritation of the detergent, so the cock had to be groped, which was extremely inconvenient.

[0004] Since it is difficult to stop the hot water and adjust the supply amount in this way, the hair is often washed while the hot water is kept flowing, resulting in a drastic increase in the hot water consumption. There was a risk that the water supply cost and fuel cost would rise sharply.

Therefore, the present invention can facilitate the operation for stopping the hot water and adjusting the supply amount of the hot water to improve its usability, and in turn, always prompt the user to perform an appropriate adjustment operation. The problem is to provide a water shut-off device for showers that can reduce hot water consumption and water and fuel costs.

[0006]

Means for Solving the Problems A shower water shutoff device according to the present invention comprises a main body disposed in the vicinity of a shower head, and a shower hose side and a shower head side formed in the main body to communicate with each other. A valve chamber having a valve seat on one side; and a valve body disposed in the valve chamber, the rotation of which is restricted by a rotation control unit of the main body, and the valve seat being capable of being closed and opened. An operating ring is provided that is rotatably fitted onto the main body and has a feed screw formed on the inner circumference thereof screwed onto the feed screw on the outer circumference of the valve body.

[0007]

[Action]

 In the present invention, the valve body, the rotation of which is restricted by the rotation restricting portion, moves in the predetermined direction through the feed screw by the rotation operation of the operation ring to close or open the valve seat, and in response thereto. Since the hot water from the shower hose is stopped or spouted from the shower head, and the operating ring is located near the shower head, the user bends when operating the operating ring. You can easily operate it by hand without changing the posture and searching for the position by groping. Also, due to the action of the feed screw, the amount of movement of the valve body is very small relative to the amount of rotation of the operating ring. , It is possible to make fine adjustments to the valve body and to make slight changes in the opening of the valve seat without paying special attention.

【Example】

 Hereinafter, an embodiment in which the present invention is embodied as a shower water shutoff adapter used by being attached to an existing showerhead will be described.

FIG. 1 is a sectional view showing a water shutoff adapter for a shower according to one embodiment of the present invention, FIG. 2 is a front view showing a water shutoff adapter for a shower according to one embodiment of the present invention, and FIG. FIG. 4 is an exploded perspective view showing a water shutoff adapter for a shower according to one embodiment, and FIG. 4 is a sectional view taken along the line AA of FIG. 1 showing a water shutoff adapter for a shower according to one embodiment of the present invention. Here, the upper side of FIGS. 1 to 3 is the upper side, and the lower side is the lower side.

As shown in the figure, the water shutoff adapter 1 of the present embodiment is mounted between a shower head 3 for ejecting hot water and a shower hose 2 for guiding the hot water to the shower head 3. The proximal block member 4 of the water shutoff adapter 1 is formed of a heat-resistant synthetic resin material into a substantially columnar shape, and an inflow hole 5 is provided along an axis L extending vertically, and an opening above the inflow hole 5 is formed. A valve seat 6 is provided around the part. A hose connecting screw portion 7 is projectingly provided on the lower end surface of the proximal end side block member 4 around the axis L, and the connecting metal fitting 2a of the shower hose 2 is connected to the hose connecting screw portion 7 to provide a shower hose. The inside of 2 and the inside of the inflow hole 5 are communicated with each other. Further, a connection screw hole 8 is formed in a predetermined depth on the upper end surface of the proximal end side block member 4 with the axis L as the center.

A tip end side block member 9 formed of a heat-resistant synthetic resin material in a substantially columnar shape is disposed above the base end side block member 4 with their axes L aligned with each other. There is. On the lower end surface of the tip side block member 9, a pair of connecting pieces 10 as rotation restricting members having an arcuate cross section are provided at predetermined intervals so that the outer peripheral surfaces of both connecting pieces 10 are the same circumferential surface. Is forming. Connecting screw parts 11 are formed on the lower portions of the outer peripheral surfaces of both connecting pieces 10, and these connecting screw parts 11 are inserted into the connecting screw holes 8 of the proximal end side block member 4 and screwed together. The base end side block member 4 and the front end side block member 9 are joined with a predetermined vertical interval. Here, in this embodiment, the main body is constituted by the base end side block member 4 and the front end side block member 9.

An outflow hole 12 is formed through the tip-side block member 9 along the axis L, and a head connection screw hole 13 is formed in the upper part of the outflow hole 12. The base end portion of the shower head 3 is connected to the head connection screw hole 13, and the inside of the shower head 3 communicates with the outflow hole 12. Since the base end of the shower head 3 and the connecting fitting 2a of the shower hose 2 are originally directly connected, they are set to have the same screw diameter, and therefore the head connecting screw hole 13 is formed. The hose connection screw part 7 is also set to have the same screw diameter. When the connection structure between the shower head 3 and the shower hose 2 is different, for example, when the screw diameter is different or the concavo-convex relationship of the screws is reversed, the proximal block member 4 and the distal block are arranged. The structure of the connecting portion of the member 9 will be changed to deal with it.

A cylindrical operation ring 14 made of a heat-resistant synthetic resin material is externally fitted to a portion from the upper portion of the proximal end side block member 4 to the lower portion of the distal end side block member 9, and these proximal end side block members are A valve chamber 15 communicating with the inflow hole 5 and the outflow hole 12 is formed between the member 4, the tip side block member 9 and the operation ring 14. The operation ring 14 is rotatable about the axis L of both the block members 4 and 9, and the movement thereof in the direction of the axis L is restricted by the steps 4a and 9a formed on the outer peripheral surfaces of the block members 4 and 9. Has been done. Further, the outer peripheral surface of the operation ring 14 is substantially flush with the outer peripheral surfaces of the proximal end side block member 4 and the distal end side block member 9 and is provided with anti-slip irregularities.

O-rings 16a and 16b are provided between the inner circumference of the operation ring 14 and the outer circumferences of the block members 4 and 9 to maintain liquid tightness between the inside of the valve chamber 15 and the outside. There is. A feed screw 17 is formed on the inner peripheral surface of the operation ring 14 between the base end side block member 4 and the tip end side block member 9, and the feed screw 17 is exposed in the valve chamber 15.

Inside the valve chamber 15, there is disposed a valve body 18 formed of a heat-resistant synthetic resin material in a substantially disc shape, and a pair of rectangular guides are formed at opposite positions of the valve body 18. A cutout portion 18a is formed. A connecting piece 10 of the tip side block member 9 is fitted in the guide notch portion 18a, and the connecting piece 10 restricts horizontal rotation of the valve body 18 about the axis L, and The vertical movement of the valve element 18 along the axis L is allowed. A feed screw 19 is formed on the outer circumference of the valve body 18, and the feed screw 19 is screwed with the feed screw 17 on the inner circumference of the operation ring 14. As shown in FIG. 4, a gap S1 is formed between the outer peripheral surfaces of both connecting pieces 10 and the inner peripheral surface of the operating ring 14, and between the inner peripheral surfaces of both connecting pieces 10 and the central portion of the valve body 18. Has a gap S2 formed therein, and the upper and lower sides of the valve body 18 in the valve chamber 15 are always in communication with each other through these gaps S1 and S2.

When the operating ring 14 is rotated in a specific direction, the valve body 18 whose horizontal rotation is restricted by the connecting piece 10 is applied with an upward force via the feed screws 17 and 19. Ascending in the valve chamber 15 along the axis L, and when the operating ring 14 is rotationally operated in the opposite direction, the valve body 18 is given a downward force and descends in the valve chamber 15.

A small-diameter disc-shaped mounting seat 18b is integrally formed on the lower surface of the valve body 18, and a packing 20 made of a rubber material is fixed to the lower surface of the mounting seat 18b by screws 21. Then, when the valve body 18 descends to the lowermost position in the valve chamber 15, the packing 20 is pressed against the valve seat 6 to close the valve seat 6, and the inflow hole 5 and the valve chamber 15 are shut off. .. Further, when the valve body 18 rises, the packing 20 separates from the valve seat 6 to open the valve seat 6, and the inflow hole 5 and the valve chamber 15 communicate with each other. The opening degree of the valve seat 6 and the opening area of the valve seat 6 at this time are determined by the vertical position of the valve body 18.

Next, the operation of the shower water shutoff adapter 1 of the present embodiment configured as described above will be described.

First, the procedure for attaching the water shutoff adapter 1 will be described. The shower hose 2 and the shower head 3 are separated, and the hose connection screw portion 7 of the water shutoff adapter 1 is connected to the connection fitting 2a of the shower hose 2. Then, the head connection screw hole 13 of the water shutoff adapter 1 is connected to the base end of the shower head 3. As a result, the water shutoff adapter 1 is attached between the shower hose 2 and the shower head 3, and the attachment work is completed. Since the water shutoff adapter 1 is directly attached to the shower head 3 as described above, the operation ring 14 is arranged in the vicinity of the shower head 1. In addition, it is assumed that the water shut-off adapter 1 at the time of completion of the attachment is such that the valve seat 6 is closed by the packing 20 of the valve body 18 and the inflow hole 5 and the valve chamber 15 are shut off.

When using the shower, the user first opens the cock (not shown) provided at the base end of the shower hose 2. Therefore, the hot water supplied to the cock is guided to the inside of the inflow hole 5 of the water shutoff adapter 1 through the shower hose 2 and is blocked by the packing 20 of the valve body 18 to prevent it from flowing into the valve chamber 15. It That is, at this time, the pressure of the hot water does not act on the inside of the valve chamber 15, and even if the liquid tightness due to the O-rings 16a and 16b is incomplete, the hot water may leak to the outside of the water shutoff adapter 1. There is no.

Next, when the shower head 3 is held and the operation ring 14 of the water shutoff adapter 1 is gripped and rotated in a specific direction, the valve body 18 receives upward force via the feed screws 17 and 19. As a result, the inside of the valve chamber 15 rises, and the packing 20 of the valve body 18 separates from the valve seat 6. As a result, the valve seat 6 is opened so that the inflow hole 5 and the valve chamber 15 are communicated with each other, and the hot water in the inflow hole 5 flows under the valve body 18 in the valve chamber 15 to form the gaps S1, S2. After that, it moves above the valve element 18 in the valve chamber 15, is further supplied to the shower head 3 through the outflow hole 12, and is ejected from the shower head 3.

At this time, the vertical position of the valve body 18 changes in proportion to the rotation amount of the operation ring 14, and the opening degree of the valve seat 6 is changed accordingly, so that the user appropriately operates the operation ring 14. While rotating, the opening degree of the valve seat 6 is changed to adjust the amount of hot water ejected from the shower head 3 to a desired supply amount.

On the other hand, when the shower is temporarily unnecessary, such as when washing the hair, the operating ring 14 is gripped and rotated in the opposite direction. A downward force is applied to the valve body 18 via the feed screws 17 and 19, and the valve body 18 descends in the valve chamber 15 to bring the packing 20 into pressure contact with the valve seat 6 to close it. As a result, the hot water is prevented from flowing into the valve chamber 15 again, and the ejection of the hot water from the shower head 3 is interrupted. After washing the hair or the like, the operating ring 14 is again rotated in a specific direction to open the valve seat 6 and spout hot water from the shower head 3 to wash away the detergent.

As described above, since the water shutoff adapter 1 of the present embodiment is configured as an auxiliary component that can be attached to the shower head 3, it can be attached to the existing shower head 3 to stop the hot water. A function to adjust water and supply amount can be added. Since the operation ring 14 when the water stop adapter 1 is attached is arranged in the vicinity of the shower head 3, the user rotates the operation ring 14 at hand while holding the shower head 3. be able to. Therefore, unlike when operating the cock at the proximal end of the shower hose 2 described in the prior art, it is not necessary to change the posture of the user such as bending over, and even when the user's eyes are closed for washing hair. The position of the operation ring 14 can be easily grasped without searching for it by hand, and the operation for stopping the hot water and adjusting the supply amount is greatly facilitated.

Further, since the operation ring 14 is configured so as to be gripped and rotated for operation, the outer peripheral surface of the operation ring 14 is set to the outer peripheral surface of the proximal block member 4 or the distal block member 9. Even if it is set to be almost the same, the operability does not deteriorate at all. Since the water shut-off adapter 1 has a substantially columnar shape with no protrusions as a whole, there is no possibility that the water shut-off adapter 1 will interfere with handling of the shower head 3 and the appearance of the shower head 3 will be improved. There is also no risk of damaging.

Further, as described above, since the rotary motion of the operating ring 14 is converted into the linear motion of the valve body 18 by the action of the feed screws 17 and 19, the valve is compared with the rotary amount of the operating ring 14 by the action. The amount of movement of the body 18 is extremely small. Therefore, the user can finely move the valve element 18 to change the opening degree of the valve seat 6 delicately without paying special attention, and the hot water ejected from the shower head 3 can be supplied in a desired amount. Adjustable quickly and accurately.

On the other hand, since the valve seat 6 is provided at the opening portion of the inflow hole 5 in the valve chamber 15, when the valve seat 6 is closed by the valve body 18, the hot water into the valve chamber 15 will not flow. Inflow is prevented and the pressure of the hot water stops working. Since the O-rings 16a and 16b are brought into sliding contact with the rotation of the operation ring 14, the O-rings 16a and 16b are gradually consumed as the water shut-off adapter 1 is used. Problems such as leakage of hot water to the outside of 1 are prevented in advance. Further, when the valve seat 6 is closed in this manner, the pressure of the hot water does not act on the O-rings 16a and 16b, so that the life of the O-rings 16a and 16b is extended.

As described above, in the shower water shutoff device of the above embodiment, the proximal block member 4 and the distal block member 9 connected between the shower hose 2 and the shower head 3, and the proximal block It is formed between the block member 4 and the tip-side block member 9 to connect the inflow hole 5 on the shower hose 2 side and the outflow hole 12 on the shower head 3 side, and to the valve seat 6 at the opening of the inflow hole 12 inside. Is provided in the valve chamber 15, and a feed screw 19 is formed on the outer periphery of the valve chamber 15. The feed screw 19 is provided by a pair of connecting pieces 10 projecting from the tip side block member 9. A valve body 18 that is capable of closing and opening the valve seat 6 by restricting rotation about the axis L and allowing movement of the feed screw 19 in a direction along the axis L, and the base. End side block member 4 and tip side block member An operating ring which is externally fitted to the shaft 9 so as to be rotatable around the axis L of the feed screw 19 of the valve body 18, and is screwed onto the feed screw 19 of the valve body 18 with the feed screw 17 formed on the inner periphery thereof. It is equipped with.

Therefore, the operation ring 14 is arranged in the vicinity of the shower head 3, and when the user operates the operation ring 14, the user does not need to change the posture such as bending or search for the position by groping. , Can be easily operated at hand. In addition, the action of the feed screws 17 and 19 allows the user to finely move the valve body 16 to change the opening degree of the valve seat 6 without any special attention. It is possible to quickly and accurately adjust the amount of hot water to be sprayed to a desired supply amount.

Therefore, the usability of the shower head 3 can be dramatically improved, and the consumption of hot water can be reduced, and the water supply cost and fuel cost can be significantly reduced.

Further, since the water-stop adapter 1 has a substantially columnar shape with no protrusions as a whole, there is no possibility that it will interfere with the handling of the shower head 3 or spoil its appearance, and the shower head 3 originally has it. It is possible to maximize the functional or external performance.

Further, when the valve seat 6 is closed by the valve body 18, the inflow of hot water into the valve chamber 15 is prevented, and the pressure of the hot water stops acting, so that the liquid in the O-rings 16a and 16b should be prevented. Even if the tightness is incomplete, it is possible to prevent problems such as leakage of hot water from the water shutoff adapter 1 and to prolong the life of the O-rings 16a and 16b. The reliability of the water shutoff adapter 1 can be improved.

Moreover, since the water shutoff adapter 1 of the present embodiment can be added to the existing shower head 3 to add the functions of stopping the hot water and adjusting the supply amount, the purchase of the water shutoff adapter 1 is possible. The various advantages described above can be obtained at a low cost.

By the way, the above embodiment is embodied as the water shutoff adapter 1 that can be attached to the existing shower head 3. However, when the present invention is carried out, the present invention is not limited to this. It suffices that it is provided in the vicinity of the shower head 3 so that the user can operate to stop the hot water spouted from the shower head 3 and adjust the supply amount. Therefore, for example, the water shutoff adapter 1 can be integrated with the showerhead 3 to form a showerhead having a built-in function of adjusting water shutoff and supply amount.

Further, the main body of the above embodiment is configured as the proximal end side block member 4 and the distal end side block member 9 which are connected to each other by the connecting piece 10. However, when the present invention is implemented, However, the present invention is not limited to this, as long as the valve chamber 15 accommodating the valve body 18 is formed inside and the operation ring 14 can be rotatably fitted outside. Therefore, for example, the base end side block member 4 and the tip end side block member 9 may be integrally formed.

Further, the valve seat of the above-described embodiment is provided at the opening of the inflow hole 5 in the valve chamber 15, and when closed by the valve seat 6, the hot water from the inflow hole 5 is removed. Although it is configured as the valve seat 6 that prevents the flow into the inside of the shower 15, the present invention is not limited to this, and the valve seat 18 closes and opens the shower to prevent the shower. It is only necessary that the hot water ejected from the head 3 can be stopped and the supply amount can be adjusted. Therefore, for example, a valve seat may be provided at the opening of the outflow hole 12 in the valve chamber 15 so that the valve body 18 closes and opens the valve seat.

On the other hand, the rotation restricting portion of the above-mentioned embodiment is formed as a pair of connecting pieces 10 which are provided so as to project from the tip side block member 9 and are fitted into the guide cutout portions 18 a of the valve body 18. When the invention is implemented, the invention is not limited to this, and it is possible to restrict the rotation of the valve body 18 about the axis L and allow the movement in the direction along the axis L. Good. Therefore, for example, the lower end surface of the tip side block member 9 is provided with four connecting pieces having an arcuate cross section and forming the same circumferential surface, and the valve body 18 is provided with four guide notches into which the connecting pieces are fitted. It is also possible to construct by providing a section.

Although the embodiment of the present invention has been described as a water stop device for a shower, it can be used as a water stop device in the middle of the pipeline because it can be arranged in the middle of the pipeline.
