DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge device for water supply and hot water supply, and more particularly to a structure for preventing water from entering a holder for accommodating a discharge head which can be used as a hand shower type. .

[0002]

2. Description of the Related Art Equipment such as a sink is provided with various taps for water supply and hot water supply. The basic configuration of the hot / water mixer tap is such that the discharge pipe protrudes from the main body of the hot / water mixer tap toward the sink and the discharge pipe can be turned left and right.

On the other hand, not only a sink but also a vanity table and the like, a hand shower type in which a discharge end portion can be used in a hand instead of a discharge pipe has been widely used. . In this hand shower type, as described in, for example, Japanese Utility Model Publication No. 4-21891, the base end of the discharge head is detachably attached to a hollow holder fixed to a wash basin and connected to the discharge head. A hose is passed through a holder and its base end is connected to a water supply and hot water supply source.

In such a hand shower type,
By providing a mechanism for switching the discharge mode in the discharge head, it is possible to perform concentrated water discharge or shower water spray like a normal faucet. Then, by grasping the ejection head by hand and pulling it out of the holder, usability different from that of the fixed hot and cold water mixing tap is possible.

In such a hand shower type,
Since water adheres to the hose when the discharge head is pulled out of the holder, it is important to prevent the adhering water from entering the holder through the hose. For this reason,
The supporting device for the water discharging device described in the above-mentioned publication also has a structure in which an annular packing that closely adheres to the peripheral surface of the hose is incorporated into the holder, and the attached water is drained off by the packing.

[0006]

The hand shower type is widely used not only in a sink but also in a hair washer and the like because the discharge head can be freely pulled out and used by hand. In other words, even though the discharge pipe can be swung by the fixed hot and cold water mixing tap, the direction of water discharge almost always falls directly below the sink, and if it is a hand shower type, the discharge head can be pulled out. If the discharge direction can be changed in various ways, it can be suitably used for hair washing and the like.

However, in the case where the posture of the discharge head is changed in various ways as described above, the hose connected to the head frequently changes not only in a straight line but also in a deformation such as bending or twisting. Will receive it. For this reason, even if a packing that drains the peripheral surface is provided when storing the hose, it is not possible to maintain a sufficient sealing force against the violent whirling and vibration of the hose when using the discharge head. There is fear.

That is, when the hose is returned to the holder after using the discharge head, the hose quickly passes through the packing, so that the surface of the hose can be drained. Prevention cannot be achieved. For example, when used for shampooing, the hair is washed while moving the ejection head in various directions, so it is highly possible that the water from the ejection head is directly covered by the inlet of the holder. It cannot be suppressed.

As described above, in the conventional equipment for drawing out the discharge head from the holder, there is insufficient water permeation into the holder. For example, a similar problem occurs when the apparatus is applied to a laundry that uses a large amount of water. is there.

The problem to be solved in the present invention is to provide a water discharge device which can surely prevent water from entering the holder side when a hand shower type discharge head is pulled out and used, and which can be used in various applications. .

[0011]

According to the present invention, there is provided a discharge head having a hose connected to a base end thereof, and a hollow storage holder in which the discharge head is detachable and in which the hose can be inserted and removed. A water discharge device having an upstream end connected to a supply source of a fluid, wherein the discharge head has a bulge portion having a large diameter in a base end direction formed on an outer peripheral surface, and a portion including the bulge portion is housed in the housing. The storage holder is configured to be immersible in the holder, and when the discharge head is immersed, the storage holder seals a gap between an inner peripheral surface of the storage holder and a peripheral surface of the bulging portion, and pulls out the discharge head. And a sealing member for sealing a gap between the inner peripheral surface of the storage holder and the peripheral surface of the hose in the closed state.

In such a configuration, the seal member may move in a direction in which the hose is pulled out from the state in which the discharge head is immersed to the state in which the discharge head is pulled out. In this case, when the discharge head is pulled out, the sealing member may have a distal end surface located substantially on the same plane as the distal end surface of the storage holder.

A first seal member for sealing a gap between an inner peripheral surface of the storage holder and a peripheral surface closer to the base end than the bulging portion when the discharge head is immersed; And a second seal member for sealing a gap between the inner peripheral surface of the storage holder and the peripheral surface of the hose in a state where the discharge head is retracted. A configuration may be adopted in which a position relative to the first seal member moves in a direction to pull out the hose until the ejection head is pulled out. In this case, the second seal member is provided between the state in which the ejection head is immersed and the state in which the ejection head is removed.
The first seal member may be configured to move to a position on the substantially same plane from the distal end surface.

Further, the discharge head is formed such that a bulge portion having a large diameter in a base end direction is formed on an outer peripheral surface, and a portion including the bulge portion can be immersed in the storage holder. The storage holder slides on the inner peripheral surface of the storage holder and moves in the immersion direction in conjunction with the immersion of the discharge head, and the movable member slides on the peripheral surface of the hose and interlocks with the immersion of the discharge head. And a resilient means for urging the seal ring in a direction in which the hose is pulled out. It has an abutting portion that abuts on the peripheral surface, moves in a direction in which the hose is pulled out in conjunction with the seal ring that moves by the bias of the elastic means, and has a front end surface substantially the same as the front end surface of the front storage holder.
When positioned on one plane, the movement is regulated, and further, when the seal ring is moved in conjunction with the mover, a peripheral surface thereof is in contact with the contact portion and a distal end surface. May be restricted to a position substantially on the same plane as the distal end surface of the moving element.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When the discharge head is immersed in and retracted from the storage holder, the inner peripheral surface of the holder, the peripheral surface of the base end of the bulging portion, the inner peripheral surface of the holder, and the peripheral surface of the hose are respectively provided. By sealing the gap between them, the gap can be sealed both when the ejection head is immersed and when the ejection head is removed, thereby preventing water from entering.

By configuring the seal member so as to move in the direction of pulling out the hose, the amount of water that accumulates when the discharge head is pulled out can be reduced, and when the discharge head is pulled out, the front end surface becomes the tip of the storage holder. By adopting a configuration that is located on substantially the same plane as the surface , the amount of water that accumulates when the ejection head is pulled out can be further reduced.

Further, in the apparatus provided with the first and second seal members, the step between the distal end surface of the first seal member and the distal end surface of the second seal member can be reduced, so that water that accumulates at the step portion is reduced. In the case where the second sealing material moves from the front end surface of the first sealing material to substantially the same plane as the first sealing material, the water that accumulates at the steps of the first and second sealing materials can be reduced. Can be similarly reduced.

Further, in the case where the movable member and the seal ring are provided and the elastic means for urging the seal ring in the direction in which the hose is pulled out is provided, the peripheral surface of the hose is sealed even after the discharge head is pulled out. Water remaining in gaps and steps in the storage holder can be eliminated.

The valve unit 37 includes an electromagnetic valve 37a connected to a water supply pipe 36a, and a mixing valve 37c having an automatic temperature control function in a flow path branched from the water supply pipe 36a and the hot water supply pipe 36b. This is a configuration in which a solenoid valve 37b is arranged downstream of 37c.

As shown in FIG. 3, a signal is input to the controller 35 by a foot switch 34, an operation unit of the water discharging device 1, a sensor (described later), and the like to control the electromagnetic valves 37a and 37b. This is performed by controlling the opening and closing operation.

FIGS. 4A and 4B show details of the valve unit 37, wherein FIG. 4A is a front view thereof, and FIG. 4B is a right side view thereof.

As shown in FIG. 1, the valve unit 37 is incorporated in the cabinet 31 and can be installed so as to absorb a construction error between the water supply and hot water supply pipes 36a and 36b. That is, for example, as shown in the figure, these water supply and hot water supply pipes 36a, 36b
The leg pipes 37d and 37e connected to the pipes are made of the same members as those applied to the ordinary hot and cold water mixing tap, so that the degree of freedom of connection with the water supply and hot water supply pipes 36a and 36b is increased, and these pipe errors are caused. Valve unit 37 that absorbs
Installation is possible.

Instead of the leg pipes 37d and 37e, one or both of them are connected to the water supply and hot water supply pipes 36a and 36b as flexible pipes, and the valve unit 37 itself is connected to the cabinet 31 with an appropriate fixture. By fixing, it is also possible to perform construction in which piping errors are absorbed.

Further, the valve unit 37 is connected to the mixing valve 37.
c at the center and water and hot water flow pipes 37f,
37g assembled together, leg tubes 37d, 37e
When three members are connected to the auxiliary tubes 37h and 37i, these can be connected by two joints 38. This joint 38 is generally called a "quick fastener", and is

With such a joint 38, in addition to being easy to assemble, it can absorb construction errors in the left-right direction, and in the case of FIG. 4, can absorb the construction errors in the vertical direction by the legs 37d and 37e. become.

Returning to FIG. 1, an operation panel 2 is provided on the front surface of the back guard 33 and near the water discharging device 1. The operation panel 2 has a main switch 2a for water discharge and water stop operation.
And a temperature switch 2b for switching the temperature of the mixed water to be discharged between high and low, and two indicator lamps 2 for respectively displaying the high and low temperatures of the mixed water.
c, 2d.

Main switch 2a and temperature switch 2
b is a tact switch type or a membrane type. When the main switch 2a is pressed once, the main switch 2a is set to the discharge side, and when pressed again, the operation of switching to the water stop side is repeated, and the function is the same as that of the foot switch 34. When the temperature switch 2b is pressed once, it is set to the low temperature side, and when it is pressed again, the operation of switching the high temperature side is repeated. On the low temperature side, only the solenoid valve 37a shown in FIG. Is supplied,
When the temperature is switched to the high-temperature side, the electromagnetic valve 37a is closed, and only the electromagnetic valve 37b downstream of the mixing valve 37c is opened, so that the water discharge device 1 is supplied with the mixed water at an appropriate temperature set by the mixing valve 37c.

The operation of the operation panel 2 causes the solenoid valves 37a, 3
7b is controlled by the controller 35. When the temperature is switched, for example, when switching from the water side to the hot water side so that the flow rate does not become excessive,
The operation of these solenoid valves 37a, 37b is controlled according to a time chart as shown in FIG.

That is, for example, when the temperature is set to the low temperature side at the end of the previous use, the main switch 2a is turned on, and at the same time, the electromagnetic valve 37a on the water supply side opens to supply water to the water discharging device 1. You. When the temperature switch 2b is pressed, the temperature is switched to the high temperature side and the solenoid valve 37a is immediately closed, but the solenoid valve 37b on the mixed water side takes a time t (approximately 0.1 second) as shown in the figure. Control is performed to open the valve after the lapse of time.

Therefore, when the electromagnetic valve 37a on the mixed water side is opened simultaneously with the closing of the electromagnetic valve 37a on the water supply side, the flow rate temporarily increases.
By delaying the opening of the valve b, an increase in the flow rate can be suppressed, and the water discharge can be stabilized.

When switching from the high-temperature side to the low-temperature side, the operation of supplying water by opening the solenoid valve 37a after the time has elapsed since the solenoid valve 37b is closed is the same. is there.

FIG. 6 is a longitudinal sectional view when the water discharging device 1 is stored in the back guard 33, and FIG. 7 is a sectional view taken along line AA of FIG.

The water discharge device 1 is provided with a discharge head 3 having a conventionally known switching mechanism capable of setting water discharge to shower water spray and concentrated water discharge by a switch button 3a, and a valve unit connected to a base end thereof and shown in FIG. The hose includes a hose 4 for connecting a flow path to the nozzle 37, and a storage holder 5 incorporated in the back guard 33 and to which the ejection head 2 can be detachably attached.

The hose 4 has a rubber hose 4b incorporated in a metal bellows tube 4a. As shown in FIG.
And a connector 4c for fixing the bellows tube 4a.
The bellows tube 4a is set to have a length slightly longer than the maximum length of the discharge head 3 that can be pulled out from the storage holder 5, and the connection end side to the valve unit 37 has the rubber hose 4b exposed. Such a bellows tube 4a and a rubber hose 4b
Due to the length relationship, the rubber hose 4b is not pulled out of the storage holder 5 even when the ejection head 3 is pulled out, so that there is no problem in appearance.

As shown in FIG. 8 and subsequent figures, by providing a duct cover 4d that can be bent around the hose 4, even if water is attached to the surface of the hose 4 and stored,
The moisture adhering to the duct cover 4d may be collected and discharged to a tray (not shown) provided at an appropriate place in the cabinet 31 or the like.

A coupler 3b for inserting and connecting the connector 4c of the hose 4 is integrally connected to the base end of the discharge head 3. The coupler 3b is a hollow body having the same diameter and tapered only at the tip end thereof. The surface of the ejection head 3 slightly spaced from the upper end thereof is raised all around the surface in a posture orthogonal to the axis of the coupler 3b. The annular seat 3c is provided as a bulging portion.

The storage holder 5 has a main body 5a inserted and fixed through a mounting opening 33a opened on the surface facing the front of the back guard 33, and is coaxially arranged in the main body 5a to be movable in the axial direction. It includes a movable element 6 and a seal ring 7 and incorporates a spring 8 for urging the seal ring 7 in a direction in which the ejection head 3 is pulled out.

The upper end of the main body 5a is formed to be slightly larger than the outer diameter of the annular seat 3c of the ejection head 3, and is located slightly behind the annular seat 3c when the ejection head 3 is in the storage position. An annular step 5b formed by widening the inner diameter is provided. The inner side of the annular step 5b has a uniform inner diameter, and the lower end is provided with a drainer 5c having an inner diameter enough to wipe water adhering to the outer peripheral surface of the bellows tube 4a of the hose 4. . Also, the main body 5a
The drain 5d is cut open on the lower surface on the back side of the back opening, and a drainage hole 33b is provided in the back guard 33 located below the drainage 5d. To allow water to drain.

The main body 5a may be structured such that a part thereof is carried by the back guard 33 instead of being incorporated into the mounting opening 33a as an integral part.

The moving element 6 has a small-diameter portion 6a having an outer diameter substantially equal to the inner diameter of the annular step portion 5b of the main body 5a at the distal end, and a large-diameter portion whose base end is substantially equal to the inner diameter of the main body 5a. 6b, and a portion between the small diameter portion 6a and the large diameter portion 6b is an annular step portion 6c. And the annular step 6c
Is mounted with a packing 6d extrapolated from the tip of the small diameter portion 6a, and the packing 6d faces the annular step 5b of the main body 5a.

The seal ring 7 has a cylindrical shape for slidingly contacting the inner peripheral surface of the moving element 6, and has a stepped portion 7a formed on the entire circumference except for a positioning portion between the moving head 6 and the discharge head 3. A packing 7b is provided. The packing 7b faces the joint 6e formed as an abutting portion on the distal end side of the moving element 6, and the packing 7b is joined to the joint 6e by a spring 8 interposed between the water drain 5c of the main body 5a. Can be adhered to.

In the above configuration, the foot switch 34
By kicking or pressing the main switch 2a of the operation panel 2, the condition of the temperature used last time, that is, water or hot water of a suitable temperature is discharged from the discharge head 3. The water can be stopped by kicking the foot switch 34 again or pressing the main switch 2a.
It is to be noted that the discharge and the water stop can be similarly performed by detecting a human hand with a sensor instead of operating such a switch.

The ejection head 3 can be used while being set in the storage holder 5 as shown in FIGS. 1 and 6, or it can be used by being gripped by hand and pulled out. Are shown in order.

FIG. 8 shows that the ejection head 3 is pulled out.
The seal ring 7 moves in the pulling-out direction by the urging force of the spring 8, and the packing 7 b attached to the step 7 a
7 shows a state in which the sheet is in close contact with the joint seat 6e. By the movement of the seal ring 7, the seal ring 7 and the movable element 6 are sealed by the packing 7b, and the seal ring 7 and the movable element 6 are water-tightly integrated around the hose 5 as an integral member. Will be besieged.

FIG. 9 shows that the discharge head 3 is further pulled out, the moving element 6 moves integrally with the seal ring 7, and the packing 6d provided on the annular step 6c of the moving element 6 is connected to the annular step 5 of the main body 5a.
b shows a state in which it is in close contact. That is, the movable element 6 moves in the pulling-out direction by the urging force of the spring 8 via the seal ring 7, and is brought into a state of being watertightly integrated with the main body 5a.

FIG. 10 shows that the ejection head 3 is connected to the back guard 33.
In this state, the movable member 6 and the seal ring 7 are kept at the same positions as those in FIG.

FIG. 11 is an enlarged sectional view of a main part for showing the positional relationship between the movable member 6 and the seal ring 7 with respect to the main body 5a in the state of FIGS.

Since the main body 5a is fixed integrally to the mounting opening 33a of the back guard 33 in advance, the space between them is completely sealed, and no water enters from outside. Further, since the packing 6d is interposed between the main body 5a and the moving element 6, a seal is formed between these peripheral surfaces to similarly block water from entering from the outside. Since the space between the movable member 6 and the seal ring 7 is also sealed by the packing 7b, intrusion of water from between them is prevented.

As described above, the coupler 3b of the ejection head 3
When the base end of the hose 4 comes off, the space between the hose 4 and the main body 5a is sealed by the mover 6 and the seal ring 7, and the hose 4 maintains this sealed state even when the ejection head 3 is further pulled out. Dripping. As is apparent from FIG. 11, when the ejection head 3 is completely pulled out, the respective distal end surfaces of the moving element 6 and the seal ring 7 are aligned on the same plane with respect to the surface of the main body 5a, Even if the surface of each of these members is covered with water, it is quickly dropped down to the basin 32 due to its inclination.

As described above, when the ejection head 3 is pulled out and used, a seal around the hose 4 is secured by the positional relationship between the movable member 6 and the seal ring 7 with respect to the main body 5a. Therefore, even if water or hot water from the discharge head 3 is directly applied to the surface of the storage holder 5, water is prevented from entering, and at the same time, water traveling on the surface of the hose 5 is similarly blocked. For this reason, even in a condition where the amount of water from the discharge head 3 is large and the water is easily covered, such as when washing the clothes using the basin 32 or washing clothes, etc., water is not allowed to enter the storage holder 5. Intrusion is reliably prevented.

When the ejection head 3 is stored in the storage holder 5, the base end of the coupler 3b pushes the distal end face of the seal ring 7 in the storage direction in the state of FIG. Move. Then, the seal ring 7 moves to a position where its lower end abuts against the bottom surface of the main body 5a. At this time, the movable element 6 has its distal end face pushed by the annular seat 3c in the storage direction, and moves to a position where its lower end abuts against the bottom surface of the main body 5a.

During this movement, the moisture adhering to the surface of the ejection head 3 and the remaining water from the ejection port enter into the main body 5a which is concave due to the lowering of the movable member 6 and the seal ring 7. On the other hand, since the packing 6d separates from the annular step portion 5b between the movable member 6 and the main body portion 5a, there is no seal, and the seal between the movable member 6 and the seal ring 7 is also released. Water also enters the mover 6. Even if such water infiltrates, the seal between the seal ring 7 and the movable element 6 and between the movable element 6 and the main body 5a has been released. 6 and between the moving element 6 and the main body 5a, and is discharged from the drain hole 33b through the discharge port 5d.

In the period in which the ejection head 3 is returned from the position shown in FIG. 10 to the final state shown in FIG. 6, the moving element 6 keeps its movement stopped, and only the seal ring 7 moves while contracting the spring 8; Thereafter, the annular seat 3c of the ejection head 3 is seated on the joining seat 6e of the movable member 6, and moves the movable member 6. During such movement of the seal ring 7, the seal 7b is released because the packing 7b is separated from the joint seat 6e of the moving element 6.

In the process of storing the discharge head 3 as described above, water enters the recess surrounded by the distal end surfaces of the movable member 6 and the seal ring 7 and the distal end portion of the main body 5a due to the entry of water. Can be considered. Also, the seal ring 7
There is a possibility that the internal water of the moving element 6 may enter between the moving elements 6 and the peripheral surfaces of the moving element 6. When the state shown in FIG. 6 is reached, the annular seat 3c of the ejection head 3 is seated on the surface side of the joint seat 6e, so that water is prevented from entering the inside of the movable member 6, and the distal end surface of the movable member 6 is prevented. The water accumulated in the recess formed by the inner peripheral wall of the distal end portion of the main body 5a is discharged from the outlet 5d through between the unsealed main body 5a and the peripheral surface of the moving element 6. You.

As described above, when the ejection head 3 is stored in the storage holder 5 after use and the ejection head 3 is pulled out and used again, even if water is accumulated in the movable member 6, the inside of the movable member 6 is shown in FIG. By moving the seal ring 7 to the state shown in FIG. 8, the accumulated water can be pushed out of the movable member 6 from around the coupler 3b passing through the inner periphery of the annular seat 6e of the movable member 6.

In the state shown in FIG. 8, the movable element 6 and the surface of the seal ring 7 are arranged side by side and are sealed by the packing 7b. The movable element 6 is sealed to the main body 5a by the packing 6d. I have. Therefore, during the transition from the state of FIG. 8 to FIG. 9, the movable element 6 is located between the movable element 6 and the surface of the seal ring 7 and the inner periphery of the mounting opening 33a.
The water that has been pushed out and accumulated from the inside is completely discharged when the movable member 6 and the seal ring 7 move to the positions shown in FIG.

As described above, when the ejection head 3 is housed, the annular seat 3c of the ejection head 3 is seated on the surface side of the joining seat 6e at the tip of the moving element 6, so that water is ejected from the ejection head 3. Even if splashing water at the time enters along the surface of the ejection head 3, the water repellent blocks the moving element 6 from entering. Even if the moving element 6 enters the inside of the moving element 6, the moving element 6 and the seal ring 7 come out of the peripheral surface of the bottom portion where the packing 7b is not provided and pass through the outlet 5d to wash the basin 32.
Can be discharged to the side. Therefore, the ejection head 3
During the period in which is set and used in the storage holder 5, water that passes through the storage holder 5 and travels on the surface of the hose 5 can be prevented, and water can be prevented from entering the cabinet 31.

Also, when the ejection head 3 is pulled out and used, as shown in FIGS. 9 and 10, the tip surfaces of the movable member 6 and the seal ring 7 are inclined so as to be flush with the surface of the main body 5a. Surface, and these parts are
Since they are sealed to each other by d and 7b, intrusion of water into the main body 5a and the moving element 6 is also prevented.

Further, when the ejection head 3 is pulled out, the water accumulated at the tip side of the main body 5a is simultaneously drained from the inside of the movable member 6, so that the hose including the time when the ejection head 3 is moved is used. 5 is prevented from entering the cabinet 31 side.

FIG. 12 shows an example in which the hose is made of vinyl chloride.

Also in this example, the structures of the main body 5a, the moving element 6 and the seal ring 7 are completely the same as those described above, and the same members are designated by the same reference numerals. And
The hose 9 made of polyvinyl chloride can be used by freely pulling out the discharge head 3 and holding it in a free posture as in the previous example due to its flexibility, and when the hose 9 is inserted into the storage holder 5 and used when pulled out. Cabinet 31 including
Water can be prevented from entering the side.

In this embodiment, the water discharge and the water stop operation are performed by the foot switch 34 or the main switch 2a of the operation panel 2. However, the sensor is used as in the conventional automatic faucet. It is also possible to perform such water discharge and water stop operation by using the same. In this case, as shown in FIG. 1, for example, a transmission window 33c is provided at a position on the front side of the back guard 33 and close to the ejection head 3 when set in the storage holder 5, and an optical type A sensor (not shown) may be incorporated. If the water is continuously discharged for a certain period of time when the sensor detects a human hand, the washing operation can be performed without using the foot switch 34 or the main switch 2a.

[0066]

According to the present invention, it is possible to remove water or a hose directly poured into the storage holder when the base end portion of the discharge head is inserted into the storage holder or when the discharge head is pulled out and the hose is extended from the storage holder. The transmitted water can be prevented from entering the storage holder. Therefore, even when the ejection head is frequently ejected and ejected, and the amount of water to be used is large, water does not enter the inside of the storage holder and the equipment on the upstream side thereof, and the maintenance of the equipment is further improved. It can be achieved more effectively.

When the base end of the discharge head is put into the storage holder after use, even if water enters and accumulates on the distal end surface side or inside the movable element, the discharge head is pulled out next. When used, the accumulated water can be forcibly removed by the movement of the moving element and the seal ring to the surface side. Therefore, accumulated water can be drained by using the insertion / removal operation of the discharge head, and deterioration of the storage holder and the members included therein can be prevented, so that the durability can be improved.
