Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet facility which can be used by connecting it to a water treatment device for purifying raw water from a water supply source or ionizing it by electrolysis.

[0002]

2. Description of the Related Art A water purifier or an alkaline ion generator is attached to a faucet to discharge ordinary raw water and purified water such as purified water. Widely used up to.

As a faucet facility for treating such raw water and discharging it, there are, for example, those described in Japanese Utility Model Laid-Open No. 2-867 and Japanese Utility Model Laid-Open No. 58-100019.

The faucet described in the former is provided with a water purifier in addition to the existing faucet, and a branching tool is attached to the tip of the water discharge pipe of the faucet to connect a flow path to the water purifier. The branching tool is equipped with a rotary operation type handle for switching the flow from the water discharge pipe to the flow path that directly discharges the water or to the water purifier, and has a flow path configuration in which a hose connects between the water purifiers.

Further, the faucet described in the latter publication is a single faucet having a shortened water discharge pipe, which is provided with a switching cock at the tip of the water discharge pipe, and the raw water can be discharged as it is or purified by operating the switching cock. The water is once branched into a flow passing through the vessel and then returned to the single end of the water discharge for discharge.

[0006]

[Problems to be Solved by the Invention]
Since the water faucet described in Japanese Patent No. 6867 is provided with a branching tool fixed to the tip of the water discharge pipe by screw joining, the operating force is directly transmitted to the branching tool connection portion and the water discharge pipe when the handle is rotated. For this reason, a large load input to the branch tool connection or a moment due to the length of the water discharge pipe easily exerts a large load on the base end, and the packing and other members of the faucet caress are deformed or bent due to the influence of the load. It may cause water leakage.

Further, the hose between the branching tool and the water purifier is in a fixed state in which the hose is closely aligned with the water discharge pipe, and when the water discharge pipe is rotated and used, the hose is pulled or loosened depending on the angle of the water discharge pipe. For this reason, the elastic fatigue of the hose is caused, and the durability is deteriorated.
It may also interfere with the operation of turning the water discharge pipe.

On the other hand, also in the one disclosed in Japanese Utility Model Laid-Open No. 58-100019, since the switching cock is fixedly attached to the tip of the water discharge pipe, the load during operation is transmitted to the faucet side, similar to the previous example. Cause problems.

As described above, in the conventional faucet equipment which is equipped with a branching tool or a switching cock at the tip of the water discharge pipe of the faucet and discharges by switching between raw water and treated water, there is an unfavorable influence due to the load of the operating force. In addition, if the hose is provided along the water discharge pipe, there is a problem in durability.

The problem to be solved in the present invention is to provide a handle having a branch structure for switching the discharge of raw water and treated water to the tip of the water discharge pipe, in order to reduce the load on the faucet side during the switching operation and to handle the handle. Is to improve the operability of the hose and to keep the hose durable.

[0011]

According to the present invention, a water faucet body which is connected to at least a water supply source and which is provided with a water discharge portion, and raw water supplied to the water faucet body from the water supply source are subjected to a required treatment. A water treatment device, the tip of the water discharge portion protruding from the faucet body, a flow passage for discharging raw water as it is, and a circulation flow passage for supplying water to the water treatment device or returning via the water treatment device. A discharge head having a switchable valve mechanism incorporated therein, the discharge head is connected to the water discharge portion with a three-dimensional degree of freedom by spherical bonding, and between the discharge head and the water treatment device, It is characterized in that the discharge heads are connected by a flow path structure that allows movement within the degree of freedom.

The water discharge part is a water discharge pipe protruding from the faucet body, the discharge head is attached to the tip of this water discharge pipe, and the flow path between the water treatment device and the discharge head is constituted by a flexible hose. The discharge head may be provided with a port for connecting a hose so as to project toward the lower surface side of the water discharge pipe.

Further, the hose and the water discharge pipe may be connected to each other by a holding band in which at least one of them can freely move.

Further, the valve mechanism can be operated by rotating operation, and a handle for rotating the valve mechanism is provided in the discharge head, and the handle is substantially parallel to the axis of the water discharge port provided at the end of the internal flow path of the discharge head. It is also possible to adopt a configuration in which it can be operated around a simple rotation axis.

[0015]

[Operation] Since the discharge head provided at the tip of the water discharge portion and also functioning as a flow path switching can freely move three-dimensionally, a buffering action for escaping in the direction in which these forces act against external force or external force during operation. Is obtained, and a large load is prevented from being applied to the base end portion of the water discharge portion.

Further, by arranging the outlet and inlet ports of the discharge head toward the lower surface side of the water discharge part, a flexible hose connected to the water treatment device is arranged so as to be along the water discharge part side. It is possible to prevent the hose from drooping largely from under the water discharge part.

Further, if the water discharge part or at least one of the hoses is restrained by a holding band so that it can move freely, the hose will follow this movement even when the water discharge part is used while turning, and the hose will be stretched or largely bent. There will be no waste.

Further, when the handle of the water spouting head is provided in a direction to rotate around the spouting port, the force of turning the handle with a fingertip does not act in the direction of pushing the water spouting portion up and down,
The load on the water discharge part is reduced. Further, even if the load of operating the handle is large, the ejection head can move three-dimensionally, so that the posture can be changed so as to follow the load, and the posture can be adjusted to fit the hand, thus improving the operability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of essential parts showing an example in which the faucet equipment of the present invention is provided in a sink.

In the figure, a faucet 1 is arranged at a position facing a sink 51 provided on a counter 50 of a sink, and a water treatment device 2 is provided on the counter 50 slightly away from the faucet 1 on the right side. The water treatment device 2 receives raw water from the faucet 1 and produces and treats it into, for example, fresh water, acidic water, alkaline ionized water, and the like, and has an operation panel 2a on its front surface for setting a treatment target. Prepared, power cord 2
b is connected to an outlet.

The faucet 1 may be an existing one installed on the counter 50 or a new one. In the illustrated example, the faucet 1 is a single lever type hot and cold water mixing faucet. This faucet 1 is connected to a water supply pipe and a hot water supply pipe (both not shown) which are arranged in the lower part of the counter 50, and a sliding valve type valve element incorporated in an internal flow path is operated by a lever 1a. It is a conventional well-known device that can discharge water, hot water, and mixed water thereof.

The body 1b of the faucet 1 is rotatably provided with a cylindrical base 3a to which the water discharge pipe 3 is integrally joined, whereby the water discharge pipe 3 can be swung. The heat insulating cap 3b provided at the tip of the water discharge pipe 3 is provided with a discharge head 4 for switching the raw water and the treated water treated by the water treatment device 2 to discharge the water.

FIG. 2 is a vertical sectional view showing the internal structure of the ejection head 4, and FIG. 3 is a bottom view thereof.

The discharge head 4 surrounds the upper cover 6, which is connected to the heat insulating cap 3b by the cap nut 5 through the adapter, the lower cover 7 connected to the upper cover 6, and the space between the covers 6 and 7. The handle 8 for operation incorporated as described above is used.

The upper cover 6 is provided with a connecting seat 6a protruding upward and having a substantially spherical outer diameter.
The flow path hole 6b is formed downward from the upper end of a. The connecting seat 6a is joined to the annular seat 5a made of, for example, rubber inside the cap nut 5 like a spherical bearing, thereby enabling the three-dimensional movement of the upper cover 6. Further, a slit 6c that opens to the space surrounded by the handle 8 is cut in the peripheral wall of the flow path hole 6b.

The lower cover 7 is substantially coaxially connected to the upper cover 5 by a screw 6d screwed from the lower end of the flow path hole 6b, and the normal water discharge port 7a for raw water and mixed water and the water passing through the water treatment device 2 are used. 7 for treated water for discharging water
b is opened.

FIG. 4 is a plan view showing the details of the lower cover 7, FIG. 5 is a vertical sectional view taken along the line AA of FIG. 4, and FIGS. 6A and 6B are respectively FIG. CC line and BB
It is sectional drawing of the principal part in a line arrow position.

The lower cover 7 is provided with an outlet port 7c for sending water from the water discharge pipe 3 to the water treatment device 2 side and an inlet port 7d for returning the water via the water treatment device 2 so as to project to the back side. These outlets and inlet ports 7c and 7d
As can be seen from FIGS. 5 and 6, has a shaft line with its tip end side facing obliquely upward.

To open / close the flow path from the water discharge pipe 3 to the outlet port 7c, a valve seat hole 7 is opened downstream of the handle pipe 8 facing upward.
e is provided, and the packing 7f is incorporated in the inner periphery thereof. Further, a valve seat hole 7g is also opened upward at the upper end of the normal water discharge port 7a, and a packing 7h is incorporated on the inner periphery thereof.
Then, the valve seat hole 7g of the normal spout 7a and the outlet port 7
It is assumed that the respective centers of the valve seat holes 7e on the c side are located on one circle centered on the core of the lower cover 7.

Further, the inlet port 7d is directly communicated with the treated water outlet 7b as shown in FIG. 6 (a), and the treated water from the water treatment device 2 is directly discharged from the treated water outlet 7b. To be done.

The handle 8 is incorporated into the upper cover 6 and the lower cover 7 so as to be coaxially rotatable with respect to the upper cover 6 and the lower cover 7 while being sealed by the packings 8a and 8b. A valve mechanism is provided for selectively opening and closing the two valve seat holes 7e and 7g of the lower cover 7 by this rotating operation.

As shown in FIG. 2, this valve mechanism is provided with a ball 8c which can be seated on the packings 7f and 7h of the valve seat holes 7e and 7g as a valve body. This ball 8c
Is held movably in the vertical direction by a cylindrical guide 8d formed inside the handle 8 and having an open lower end, and is urged downward by a spring 8e and a pusher 8f.

At the outlet port 7c and the inlet port 7d,
The supply hose 9 and the recovery hose 10 connected to the water treatment device 2 are connected to each other. These hoses 9, 10
The ports 7c and 7d are connected by inserting them, and the surroundings are fixed by using a simple clip.

The supply hose 9 and the recovery hose 10 are shown in FIG.
As shown in FIG. 1, the holding band 11 is restrained so as to run along the water discharge pipe 3. The holding band 11 is preferably made of a plastic material, and for example, as shown in FIG. 7A, has a ring 11a to be fitted around the water discharge pipe 3 and a band 11b integrated with the ring 11a. It is a thing. A large number of recesses 11c are opened in the strip 11b, and the strip 11b is passed through the cavity in the lower part of the ring 11a as shown in FIG.
By fitting a part of 1d into the recess 1c, the strip 1
1b can be wound up in a loop.

Here, the holding band 11 is free to move with respect to at least one of the discharge pipe 3 and the bundle of the hoses 9 and 10, or is free to move with respect to both. For example, in order to move freely with respect to the water discharge pipe 3, the ring 11a may be loosely fitted into the water discharge pipe 3, and when the bundle of hoses 9 and 10 is moved, the projection 11d is fitted. Round hole 11
The loop is enlarged by making c suitable, and hose 9,1
The movement in the direction of passing through 0 is made prompt.

As the supply hose 9 and the recovery hose 10, for example, those made of vinyl chloride as the material of which the inner wall side is subjected to antibacterial treatment, those having a polyethylene layer provided with antibacterial property formed therein, and the like can be used. In this case, the vinyl chloride material has sufficient softness so that there is no problem in flexibility, and the polyethylene material can be sufficiently flexible if the layer is thinly formed. . A specific example of such hoses 9 and 10 is shown in FIG.

In FIG. 8A, the supply hose 9 and the recovery hose 10 are common parts made of the same material, and the outer layers 9a and 10a made of vinyl chloride and the vinyl chloride-based material having antibacterial properties are used. The inner layers 9b and 10b have a two-layer structure, and the layers 9a, 10a, 9b, and 10b are integrally joined with mesh-like blades 9c and 10c for providing pressure resistance.

If such a vinyl chloride material is used, the supply hose 9 and the recovery hose 10 can be manufactured as soft ones, and piping between the faucet body 3 and the water treatment device 2 can be easily performed. Further, although vinyl chloride is inferior in mechanical strength, it can be compensated by incorporating the blades 9c and 10c, and the pressure resistance against normal tap water pressure is secured.

In the example of (b) of the figure, the supply hose 9 is the same as the previous example, but the recovery hose 10 is an outer layer 10d made of vinyl chloride and an inner layer 10 made of polyethylene with antibacterial properties.
e is joined by an appropriate adhesive 10f.

Since the inner layer 10e made of polyethylene is harder than vinyl chloride, the inner layer 10e is formed into a thin film so that the recovery hose 10 can be easily bent. Further, since the treated water passing through the recovery hose 10 side corresponds to the secondary side flow path of the water treatment device 2, the pressure is somewhat attenuated, so that a reinforcing structure such as a blade is not necessary. Since the inner layer 10e is made of polyethylene with antibacterial properties, the antibacterial effect is much larger than that of the case where vinyl chloride is used, and it is an optimal flow path structure for sending treated water to its supply destination. is there.

In the above construction, when raw water or mixed water of hot water and hot water is used, the lever 1a is moved up and down or turned left and right to open and close the flow path and adjust the temperature and flow rate of the mixed water.

When only the raw water is supplied or when the mixed water with the hot water is discharged, the handle 8 is turned counterclockwise as viewed from the bottom surface side in the state shown in FIG. The handle 8
Using the index protrusion 8g provided on the peripheral surface of the
Notify that the switching is performed in the rotation range as shown in.

By rotating the handle 8, the normal spout 7
The ball 8c seated in the valve seat hole 7e on the a side rolls on the upper surface of the lower cover 7 while contracting the spring 8e, and finally the ball 8c on the valve seat hole 7g on the side of the treated water discharge port 7b is closed. Sit on packing 7h. As a result, the flow path to the water treatment device 2 side is completely blocked, and the raw water or the mixed water from the water discharge pipe 3 is normally discharged from the water discharge port 7a.

Further, in order to switch from the normal water discharge to the treated water discharge, the handle 8 is turned in the opposite direction to the previous operation, and the ball 8c is seated on the packing 7f of the valve seat hole 7e as shown in FIG. . As a result, the discharge from the normal water discharge port 7a is eliminated, and the valve seat hole 7g is opened, so that the raw water can be supplied from the outlet port 7c to the flow passage on the supply hose 9 side.

If water is supplied in this state, the raw water is subjected to a predetermined treatment here toward the water treatment device 2, and the recovery hose 1
After passing through the inlet port 7d from 0, it is discharged from the treated water discharge port 7b as described in FIG. 6 (a).

When switching is performed by rotating the handle 8 as described above, the acting force for rotating the discharge head 4 is supplied to the water discharge pipe 3 via the connecting seat 6a which can move like a universal joint using a spherical surface. Transmitted to the side. At this time,
For example, even if the ejection head 4 is rotated in a twisted direction with respect to the axis of the ejection head 4, the ejection head 4 changes its posture so as to follow this twist by the spherical surface of the connecting seat 6a. Therefore, no unreasonable external force is applied to the water discharge pipe 3 side when the handle 8 is rotated, and the water discharge pipe 3 is long and the load applied to the base end portion by the moment is reduced.

Further, since the handle 8 is an operation for turning the spouting water from the normal spouting port 4a and the treated water spouting port 7b on the lower surface of the ejection head 4, the operating force for pushing the spouting pipe 3 up and down. Does not occur, and even if the moment due to the length of the water discharge pipe 8 is large, the load between the base end portion of the water discharge pipe 3 and the main body 1b is further reduced. Then, when the handle 8 is operated, the ejection head 4 can be pulled up and turned to the front side, and the hand can be comfortably hung and operated, and the usability is improved.

Further, the ejection head 4 is, for example, an actual flat opening 2.
Unlike the one fixed rigidly by screwing or the like as described in JP-6867, it is attached to the water discharge pipe 3 as a one having a degree of freedom in a three-dimensional direction by a spherical connecting seat 6a. There is. Therefore, even when an external force is applied or when the handle 8 is turned, it is possible to buffer the impact and the external force by such a degree of freedom.
The load on the base end of the water discharge pipe 3 can be reduced.

By thus forming the connecting seat 6a in a spherical shape, an increase in load on the base end side of the water discharge pipe 3 is prevented,
The heat insulating cap 3b is not broken or the seal on the main body 1b side is not affected.

The outlets and inlet ports 7c and 7d connecting the supply and recovery hoses 9 and 10 are in an obliquely upward posture as described with reference to FIG.
The directivity of 0 is given to the lower surface of the water discharge pipe 3. Since the bundle of hoses 9 and 10 is constrained by the holding band 11, the bundle of hoses 9 and 10 is held in a position close to the water discharge pipe 3. For this reason, the hoses 9 and 10 do not drastically hang down downward, and do not interfere with the work of washing dishes and the like in the sink 51, and the space inside the sink 51 can be effectively used.

Further, if the holding band 11 for restraining the bundle of supply / recovery hoses 9 and 10 on the side of the water discharge pipe 3 is allowed to freely move with respect to the water discharge pipe 3, the water discharge pipe 3 is rotated when the water discharge pipe 3 is rotated. The holding band 11 holds the bundle of supply and recovery hoses 9 and 10 on the side of the water discharge pipe 3 so as to follow the movement. For this reason,
Compared to the case where the supply / recovery hoses 9 and 10 are firmly fixed to the water discharge pipe 3, these hoses 9 and 10 are not stretched or loosened significantly, and the movement of the water discharge pipe 3 is also resisted. Never. Therefore, even with a structure in which the supply and recovery hoses 9 and 10 are entangled along the water discharge pipe 3, the water discharge pipe 3 can be easily turned and used, and there is no effect on usability.

Further, the shape of the ring 11a is set so that the holding band 11 can be firmly fixed at a predetermined position of the water discharge pipe 3, and the supply and recovery hoses 9 and 10 are loosely restrained by the band 11b so that they can be moved freely. The same applies to the case. Then, even when the holding band 11 can be moved with respect to both the supply and recovery hoses 9 and 10 with respect to the water discharge pipe 3, the same operational effect can be obtained.

[0053]

According to the present invention, since the discharge head can freely move three-dimensionally, it can have a buffering effect against the force and external force at the time of operation and can be connected to the water discharge part and the base end part of the discharge part. It is possible to use it without exerting a heavy load on it and without adversely affecting the seal inside the faucet body.

Further, by directing the outlet and inlet ports of the discharge head toward the lower surface side of the water discharge part, it is possible to form a hose for connection as a pipe along the water discharge part, and to install it in a sink or the like. Moreover, the hose does not interfere with the washing work.

Furthermore, by restraining at least one of the water discharge part and the hose by a holding band so that they can move freely, the hose will not be stretched or loosened even when the discharge head is rotated and operated, which hinders the work. The durability of the hose itself is also improved.

Further, since the switching handle is provided so as to rotate in the direction around the spout, no action force is exerted to push the spout up and down, and the base end of the spout is also operated. By utilizing that the load of can be reduced and the posture of the ejection head can be freely changed, it becomes easy to put the hand on and turn it, and the operability is improved.
