Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device. More specifically, the present invention relates to a water supply device having a cleaning ball with a water tap.

[0002]

2. Description of the Related Art A conventional water supply device is designed so that it can be attached to a cleaning ball by selecting one from a plurality of faucets.
The cleaning ball and the faucet were manufactured separately, and were also manufactured using different materials. For example,
The cleaning ball is made of pottery, stainless steel, and a synthetic resin material, while the faucet is made by plating a copper alloy. As described above, the cleaning balls and the faucets were designed and manufactured separately, and the structure was not such that the cleaning balls and the faucet had a sense of unity.

Further, in the conventional water supply device, a faucet mounting hole is provided on the counter surface of the cleaning ball, and the faucet is separately mounted through the mounting hole. Therefore, a seam occurs at the boundary between the cleaning ball counter and the faucet fitting,
Water droplets scattered by hand washing and the like were likely to accumulate on the joints and stains. Furthermore, it is the current situation that dirt enters the seams and is difficult to maintain.

Furthermore, since the faucet and the ball are separate bodies,
If the faucet was loosened during long-term use, water could intrude from the seam through the mounting hole on the back surface of the counter where the cleaning ball is placed.

Further, the automatic water faucet operates by reading the amount of the reflected light reaching the light receiving element (light receiving amount) when the infrared light projected from the sensor hits the ball surface. Here, since the automatic faucet and the wash bowl are conventionally provided as separate bodies, there is an advantage that they can be attached to wash bowls of various shapes. Then, after selecting a wash basin of preference and mounting the wash basin on site, an automatic water faucet is attached and the detection setting of the sensor is performed. This detection setting is when the infrared ray projected from the sensor is reflected by the ball surface after the automatic faucet is attached to the wash bowl and the light receiving level received by the sensor is constant light intensity for a certain time,
The value is stored as the light receiving level in the unused state. Conventionally, an automatic water faucet is installed separately from the counter of the cleaning ball, so the installation of the automatic water faucet loosens during long-term use, and the automatic water faucet shifts and the direction of light emitted from the sensor changes. , The distance from the sensor to the reflection surface of the projected light might change. In this case, the amount of received light may exceed the light receiving level in the unused state, the sensor may erroneously detect, and water may be left unintentionally in spite of the unused state. Therefore, in order to always be able to use it with peace of mind for a long period of time, it is necessary to check whether the faucet is securely attached. In addition, the reality is that when the faucet is loosely installed, it receives a notification and responds to it each time, and during that time, it cannot be used.

[0006] Further, the automatic faucet is sanitary because it can supply water without touching the faucet metal fittings, and in particular, it is a toilet (hand-washing place) in public facilities such as airports, station buildings and highway parking areas. Can be said to be suitable for. The water supply device used in such public facilities is installed as a set of pottery and a faucet. However, unlike the use in a general household, the use in a public facility is sometimes handled roughly, and as a result, there is a problem that the pottery is broken. Further, in the case where the cleaning ball is made of ceramics, since it has a considerable weight (5 kg to 20 kg), it is a reality that construction on site is difficult.

[0007]

Therefore, the inventor of the present invention
For a long time, we have conducted diligent research to provide a water supply device that can be installed and used in public facilities, maintains high quality and hygiene, and has high durability. Furthermore, the research item was to make it easy to install and install. Conventionally, the faucet and the cleaning ball were designed separately, but the present inventor changed the design concept so far to provide the excellent water supply device described above, and the faucet and the cleaning ball were designed. I thought about designing at the same time.

Further, in public facilities, a state in which a previous user has soiled the cleaning ball (for example, a state in which hair or the like remains on the cleaning ball without flowing from the drain port).
In the case of, the following user must use it while feeling very uncomfortable. Therefore, the next research item is that the user always uses the cleaning ball comfortably. In order to solve this problem, further research was conducted on having a water discharge function part for discharging water to the cleaning ball surface.

A conventional technique for discharging water to the surface of a cleaning ball has been disclosed in Japanese Utility Model Publication No. 51-642339. However, with this technique, it is difficult to uniformly discharge water over a wide area of the cleaning ball surface without providing a plurality of water discharge ports. The reason is that the cleaning ball has a corner portion and the cleaning water is blocked from the corner portion and does not flow to the tip, so that it is difficult to discharge water over the entire surface of the cleaning ball. Therefore, by providing a plurality of water discharge ports, the cleaning area of the cleaning ball can be widened, while cleaning work becomes difficult when dirt is accumulated at the joints of the water discharge ports.

As a conventional technique for discharging water onto the surface of the cleaning ball, Japanese Patent Application Laid-Open No. 5-16856 filed by the present applicant.
There is No. 6. The applicant has commercialized a cleaning ball with a water discharge function by introducing this technology. This cleaning ball is installed in an office building or the like and is used as a cleaning ball for brushing teeth after lunch. at that time,
In Japan, the lifestyle has changed and the number of people who brush their teeth after lunch has increased. When using a wash ball that is usually used for hand washing, toothpaste (toothpaste) may adhere to the wash ball when the mouth is rinsed. Therefore, in order to flush the adhered toothpaste, it is necessary to draw water into the cup and pour water on the toothpaste many times, or to guide water from the water supply port by hand to flush. Therefore, in order to easily wash off the adhesion of the toothpaste described above, the present applicant has provided a cleaning ball for toothpaste having a water discharging function without providing a corner portion on the inner surface of the cleaning ball so that water can be discharged over a wide area of the cleaning ball. It was developed. However, as a ball washing function, a discharge port fitting for washing balls is attached to the inner surface of the pottery. Since the outlet fitting is attached separately to the hole provided in the ball, it is easy to get dirty at the joint between the ball and the outlet fitting, and it is difficult to clean as in the case of installing the above faucet. Was left.

Further, since the cleaning ball is deep, it is necessary to prevent the water from immediately flowing down toward the bottom surface of the ball due to gravity after the water is discharged in order to spread the water over the entire area of the cleaning ball. Therefore, it is necessary to make the cleaning ball small. Therefore, the diameter of the cleaning ball that is usually used for hand washing is about 400 to 500 mm, while the diameter of the commercialized cleaning ball for toothpaste is
It is about 300 mm. Therefore, the present inventor further solves the above-mentioned problems, and sprays a small amount of water on a cleaning ball (diameter of about 400 to 500 mm) installed in a public facility, and sprays water on the entire cleaning ball without increasing the flow velocity. However, by washing off simple stains, we worked hard to provide a more comfortable cleaning ball.

The object of the present invention is to solve the above problems.
It is an object of the present invention to provide a water supply device in which a cleaning ball and a faucet have a one-piece structure, and the cleaning ball is provided with a faucet to improve the usability. Further, it is another object of the present invention to provide a water supply device capable of maintaining hygiene for a long period of time by simple cleaning by eliminating the seam at the boundary between the water faucet and the cleaning ball. Further, it is another object of the present invention to provide a water supply device that can maintain high quality usability for a long period of time without causing a sensor to make an erroneous detection due to loose attachment of a water faucet. In addition, when a water supply device is installed in a public facility used by multiple different people, keep the cleaning ball clean by the previous user's use so that the next user can use it comfortably. It is an object of the present invention to provide a water supply device with a water discharge function that discharges water onto the surface of a cleaning ball.

[0013]

In order to solve the above problems, in the invention of claim 1, a cleaning ball having a drain port and a water supply pipe are connected to supply water into the cleaning ball. A water faucet having a water supply port for the purpose of the above, and the water faucet exterior part and the cleaning ball are formed of the same material.

As a result, the water faucet and the cleaning ball can be made to have a feeling of unity, and the appearance and the feeling of use can be improved.

According to a second aspect of the present invention, there is provided a cleaning ball having a drainage port, and a faucet connected to a water supply pipe and having a water supply port for supplying water into the cleaning ball. The plug exterior part and the cleaning ball are formed of the same material, and the exterior part of the faucet is seamlessly and integrally formed with the cleaning ball.

As a result, even if water drops or dirt adheres to the boundary between the water faucet and the cleaning ball, it can be easily removed, and hygiene can be maintained for a long period of time with simple cleaning. Further, in the present invention, since there is no joint between the water faucet and the cleaning ball, there is no possibility that water will infiltrate from the joint to the back side of the ball as in the conventional case. Especially in places where multiple units are installed and where cleaning is required in a short time, such as public facilities,
The effect of the present invention is greatly exerted.

According to a third aspect of the present invention, there is provided a cleaning ball having a drainage port, and a faucet connected to a water supply pipe and having a water supply port for supplying water into the cleaning ball. The faucet exterior part and the cleaning ball are formed of the same material, and the exterior part of the faucet is seamlessly integrated with the cleaning ball. Furthermore, the faucet is supplied with water and stopped by a sensor. That is, the water supply device is an automatic faucet for supplying water.

As a result, even if water drops or dirt adheres to the boundary between the water faucet and the cleaning ball, it can be easily removed, and hygiene can be maintained for a long period of time with simple cleaning. Further, in the present invention, since there is no joint between the water faucet and the cleaning ball, there is no possibility that water will infiltrate from the joint to the back side of the ball as in the conventional case. In addition, when water penetrates from the seam, the reinforcing plate supporting the cleaning ball may be rotten and the strength may be reduced. Especially in kitchen faucets, the kitchen cabinet itself (wooden) is likely to rot.

In addition, since the conventional faucet is attached separately to the cleaning ball, if the faucet is loosened and the water supply direction of the faucet changes due to long-term use, the sensor installed in the faucet Since the position is displaced and the positional relationship between the sensor and the ball surface is changed, there is a risk of false detection. On the other hand, in the present invention, since the spout and the ball are integrated, such a problem does not occur at all.

Incidentally, in the faucet with a handle that has been widely used in the past, the handle is rotated to supply water. Therefore, for those who do not know how to use the automatic faucet, the main body of the automatic faucet may be mistakenly turned like water is supplied from the faucet with a handle, and the faucet may become loose or the sensor may not be thrown. Although the light direction may change, such a problem can be solved by forming it integrally.

Therefore, in particular, in a place where a plurality of public facilities are installed and the quality must be maintained under a bad use condition for a long time and the hygiene can be maintained in a short time, The effect of the present invention is greatly exerted. In addition, since the automatic water faucet can be suppressed to a predetermined water supply flow rate, it also leads to a water saving effect.

According to a fourth aspect of the present invention, there is provided a cleaning ball having a drainage port, and a faucet connected to a water supply pipe and having a water supply port for supplying water into the cleaning ball. The stopper exterior part and the cleaning ball are formed of the same material, and the exterior part of the faucet is formed integrally with the cleaning ball seamlessly, and further, the faucet is

Thus, it is possible to prevent the cleaning ball from being left with dirt (hair and sputum of the previous user), and the user can always use a clean cleaning ball. Further, the water passages can be concentrated at one place, the workability is improved as compared with the separate type, and the joints can be eliminated to suppress the stain in the vicinity of the faucet. Further, according to the configuration of the present invention, even if the water discharge port is provided in the cleaning ball, the water discharge port is not submerged in water. In addition, the water supply device can have an innovative design that is excellent in terms of design, and can provide a user with a more comfortable feeling than ever before.

In the invention of claim 5, the faucet is
That is, the water supply device is such that the boundary with the cleaning ball is formed by a seamless curved surface.

As a result, dirt may have accumulated on the seams in the past, and cleaning was difficult, but smooth integration improves the cleanability and allows water to be discharged smoothly along the surface of the cleaning ball. Can also be discharged.

According to the invention of claim 6, the material of the cleaning ball and the material of the exterior part of the faucet are stainless steel.

As a result, conventional cleaning balls made of ceramics are heavy and therefore difficult to install, but stainless steel is light in weight and therefore easy to install. In addition, it has excellent durability and does not cause a problem of cracking due to being dropped or being intentionally broken. In particular, it is more effective at a site where a plurality of water supply devices must be installed, such as public facilities.

According to the invention of claim 7, the faucet is
The water supply device has a bridge shape, and the water supply port is provided at the center of the bridge, and the water is discharged to the cleaning ball surface provided with the water discharge port on each of the bridge legs.

As a result, the water supply port can be easily positioned forward, and handicapped persons in wheelchairs can easily wash their hands. In addition, the bridge also serves as a handrail, and it is possible to wash the hands by leaning forward while holding the bridge while supporting the body, such as elderly people with weak muscles and people with back injuries. it can.

In the invention of claim 8, there is no seam on the downstream side of the water discharge port, and the cleaning ball surface from the water discharge port to the drainage port is arranged in the water discharge direction from the water discharge port to the cleaning ball. It is a water supply device with a water discharge function that discharges water onto the surface of the cleaning ball, which has a smooth streamlined structure.

As a result, the water discharged to the cleaning ball is
The shape of the ball does not interrupt the progress on the way,
Can flow over a wide area of the wash ball.

In the ninth aspect of the present invention, the cleaning ball has a cleaning ball surface whose upper side is curved to have a convex shape in one longitudinal cross section and whose lower side is curved to have a concave shape in one vertical cross section. It is a water supply device with a water discharge function that discharges water.

As a result, the speed of the water discharged from the water discharge port falling due to gravity is weakened by the upper convex curved portion, and the water can be evenly distributed over the entire cleaning ball surface. Therefore, the inner surface of the ball can be firmly discharged with a small amount of water.

According to a tenth aspect of the present invention, there is provided a water supply device with a water discharge function for discharging water to a cleaning ball surface, wherein a part of or the entire circumference of the inner surface of the cleaning ball is provided with a step along a water discharge direction from a water discharge port. That is what I did.

As a result, the speed of the water discharged from the water outlet is lowered by gravity due to the step provided along the water discharge direction from the water outlet, and the water can be evenly distributed over the entire cleaning ball surface. Therefore, the inner surface of the ball can be firmly discharged.

In the eleventh aspect of the present invention, the water supply device is provided with an air bubble mixing means for mixing air bubbles into the water supply at the water supply port.

As a result, even if the ball is thin and the inclination angle of the ball surface is made small so that the speed of falling due to gravity is weakened and the water is spread over the entire area of the cleaning ball, the water is mixed with bubbles. At times, the water supply does not hit the cleaning ball and the water does not splash around and flood the area. Therefore, the area around the cleaning ball is not always wet with splashed water, and even if an accessory is placed near the cleaning ball, it can be safely placed without getting wet. In addition, by mixing air bubbles, it is possible to reduce the amount of water supply compared to the conventional amount of water discharge, which leads to a water saving effect. In this way, the effect of preventing splashing of water is great and the cleaning ball can be made thin, so that the range of design of the shape of the cleaning ball can be expanded and a novel design can be provided.

In this case, no step is formed at the joint between the faucet mounting portion and the faucet 10. Further, the boundary portion 8 between the faucet 10 and the cleaning ball 2 may be formed by welding so as to have a seamless curved surface. (Figure 19)

Here, the faucet 10 may be one in which an opening / closing valve is opened and closed by a handle lever to supply water, but further, it is an automatic faucet 10a which performs water supply and water stoppage by detection of a sensor 13. By doing so, it is possible to improve near-futuristic design and usability. In particular, in the case of an automatic faucet, it can be said that it is more hygienic because water can be supplied and stopped without touching the faucet 10. The water supply function part of the faucet 10 includes at least an on-off valve and a water supply port 1.
Equipped with 2. Particularly, in the case of the automatic faucet 10a, at least an electromagnetic opening / closing valve 16 (hereinafter referred to as an electromagnetic valve), a controller 18 for controlling the opening / closing of the electromagnetic valve 16, a sensor 13 for transmitting a signal of this opening / closing, a water supply port 12, a power source. Is equipped with. Although the water supply port 12, the sensor 13, the solenoid valve 16 and the controller 18 may be embedded in the faucet exterior part 11 at a location distant from the cleaning ball 2, only the water supply port 12 and the sensor 13 are embedded. By providing other functional parts outside the faucet exterior part 11, the shape of the faucet 10 can be freely designed. (FIGS. 14 and 15) Further, it is preferable to provide a check valve near the water supply port 12.

A water discharge port 20 for discharging water along the cleaning ball 2 is provided in the water stopper 10 or the cleaning ball 2 at the boundary portion 8 between the water stopper 10 and the cleaning ball 2. In particular, it is preferable that the water faucet 10 be mounted in the cleaning ball 2 with a water discharging function part (water discharging unit) having a water discharge port 20 for discharging water to the cleaning ball 2. In addition, the water discharge unit is a connection part 17a connecting at least the water supply pipe 17 and the connection part 17a to the water discharge port 20 so that water can be discharged from the water discharge port 20 in a fan shape along the inner surface of the cleaning ball 2. It means a member that forms a water passage.

The water discharge function unit for discharging the water has at least a water discharge port 20 (water discharge unit), a solenoid valve 22, a controller 18 for controlling opening / closing of the solenoid valve 22, and a signal for opening / closing the solenoid valve 22 to the controller 18. It has a sensor 13 for transmitting and a power source 32. In addition, the outlet 20
It is preferable to provide a check valve in the vicinity of.

Further, there is no joint on the downstream side of the water discharge port 20, and the surface of the cleaning ball 2 from the water discharge port 20 to the drainage port 7 flows smoothly in the water discharge direction from the water discharge port 20 to the cleaning ball 2. More preferably, it is configured linearly.

The water supply port 12 and the water discharge port 20 are preferably provided in the surface of the cleaning ball 2 and at a position higher than the lowermost position 5a of the rim 5 of the cleaning ball 2. In particular, when a drain plug (not shown) that can be opened and closed is provided at the drain port, an overflow hole (not shown) is provided, and the water supply port 12 and the water discharge port 20 are provided at a position higher than the overflow hole.

Further, by using stainless steel as the material of the above-mentioned cleaning ball, it is possible to reduce the weight as compared with pottery. In particular, when it is used under adverse conditions than when it is used in public facilities, it is preferable to use stainless steel in consideration of durability, strength, corrosiveness, lightness and the like.

The faucet exterior portion 11 of the faucet 10 and the cleaning ball 2 may be made of different materials.
When the faucet exterior part 11 and the cleaning ball 2 are made of the same material or the same color, the cleaning ball 2 to the faucet 10 can give a continuous sense of unity to the user.
A comfortable water supply device 1 can be provided. The material can be, for example, stainless steel, aluminum, or synthetic resin. And, further, the faucet exterior portion 1 of the faucet 10
In the case where the cleaning ball 2 and the cleaning ball 2 are made of the same material by welding and are connected to each other and then ground to be integrally formed seamlessly, the cleaning ball 2 to the faucet 10 are continuous.
You can create an unprecedented sense of unity.

Next, a specific embodiment of the water supply device 1 having a water discharge function for discharging water to the surface of the cleaning ball 2 will be described in detail with reference to the drawings.

First, an embodiment of the present invention will be described with reference to FIGS. In FIG. 1, in addition to the above-described configuration, the water faucet 10 has a shape that considerably protrudes from the cleaning ball 2. A sensor 13 and a water supply port 12 are provided at the tip of this faucet. Due to the shape of the faucet 10, a space for hand washing can be secured between the water supply port 12 and the drainage port 7. The cleaning ball 2 used here has a thin shape (here, the thickness from the lowermost portion 5a of the rim 5 to the bottom surface of the cleaning ball 2 is about 100 mm, usually about 150 mm) to improve the design. ing. In addition, by making the cleaning ball 2 thin, a sufficient space under the cleaning ball 2 can be secured, and the cleaning ball 2 can be placed under a cleaning wheel 2 under a wheelchair or while sitting on a chair. You can put your legs firmly in the side space and perform actions such as hand washing with a comfortable posture. Further, the cleaning ball 2 has a flat outer peripheral lower end of the rim 5, and has a shape such that the water supply device 1 can be easily installed by placing the outer peripheral lower end of the rim 5 on the opening of the counter. There is. Further, the upper end of the outer periphery of the rim forms a downward slope from the rear where the faucet is installed to the front.

When the cleaning ball 2 has a thin shape as described above, there is a high possibility that the water supplied from the water supply port 12 hits the cleaning ball 2 and bounces to wet the periphery of the cleaning ball 2. Therefore, in order to prevent water splashing, air bubbles (preferably fine air bubbles) are mixed in the water supply. As a bubble mixing means for mixing bubbles in the water supply, there are a method of entraining air at a flow velocity of water, a method of forcibly feeding air by a pump, and the like. Then, the bubble mixing means is provided in the water supply port 12 of the faucet 10 or in the water supply pipe path, so that bubbles can be mixed into the water supply. FIG. 4 shows an example of a foam cap attached to the tip of the water supply port 12 as the bubble mixing means 35.
In order to make the bubbles finer, it is preferable to provide a plurality of meshes 36 (a plurality of fine holes may be arranged in parallel in the water supply direction) in the water supply direction of the water supply port 12 to diffuse the bubbles.
As a result, in the conventional automatic faucet 10a, the water supply amount was 5 L per minute, but with a water supply amount of 4 L or less per minute, it is possible to obtain a sufficient water supply feeling and a cleaning effect such as hand washing. Therefore, it is possible to save a lot of water when it is frequently used in public facilities. In addition, the inclusion of air bubbles also prevents water from splashing from the surface of the cleaning ball 2, which is particularly effective when the cleaning ball 2 is thin.

The water discharge port 20 is located at the back side of the cleaning ball 2 and at the base of the faucet 10. The water discharged from the water discharge port 20 reaches the front side of the cleaning ball 2 and flows to the entire area (wide area) of the cleaning ball 2. In this way, the surface of the cleaning ball 2 is formed into a gentle curved shape so that the discharged water flows over the entire area (wide area) of the cleaning ball 2. If the cleaning ball surface has a projection or an angled shape other than the faucet, the water discharge is blocked there,
This is because it cannot flow over the entire area of the cleaning ball 2, and a plurality of water outlets 20 must be provided inside the cleaning ball 2.

As for the shape of the cleaning ball 2, the upper side is curvedly formed into a convex shape 3 in a one-sided vertical cross-sectional view, and the lower side is curvedly formed into a concave shape 4 in a one-sided vertical cross-sectional view. Further, since the water discharge port is provided in the convex shape 3 portion on the back side of the cleaning ball 2, when the water discharge flows, the water flows from the water discharge port 20 onto the upper convex shape 3 first, and along the cleaning ball 2. The downward gravity can be suppressed, and the water can be sprayed over the entire area of the cleaning ball 2 without flowing directly to the drain port 7, and the cleaning area by the water spray can be expanded.

Further, as shown in FIG. 5, a part or all of the inner surface of the cleaning ball 2 is sprayed so that the sprayed water does not flow downward due to gravity before it reaches the entire area of the cleaning ball 2. Water discharge direction from water outlet 20 (circumferential direction)
A step 9 can be provided along the line to allow water to flow over the entire area of the cleaning ball 2 to widen the cleaning area by water discharge. In addition,
It is preferable that the step 9 is a gentle step 9 having a gentle curved shape so that dirt is not easily attached.

FIG. 2 is a front view of the water supply device 1 of FIG. The water supply port 12 and the water discharge port 20 are higher than the lowermost position 5a of the rim 5 to form an air gap. Further, FIG. 3 is a side view of the water supply device 1 of FIG. As shown in FIG. 3, since the rim 5 is tilted from the back side toward the front to make the front of the rim 5 the lowest,
A sufficient space between the water supply port 12 and the drainage port 7 can be secured, and when washing the hand, it is easy to put the hand in the space of the washing ball.

Next, another embodiment will be described with reference to FIGS. In the water supply device 1 shown in FIG. 6, the water faucet 10 has a shape that hardly protrudes from the upper end of the rim of the cleaning ball 2. As shown in the figure, this faucet 10
Is provided in the cleaning ball as a rounded and substantially triangular pyramid shape. The cleaning ball 2 has a concave shape 4 (almost hemispherical shape) different from the shape of the cleaning ball 2 in the water supply device 1 of FIG. 1, and has a depth on the far side of the ball (here, the rim 5). The thickness from the uppermost portion to the bottom surface of the cleaning ball 2 is about 150 mm, provided that the thickness from the lowermost portion 5a of the rim 5 to the bottom surface of the cleaning ball 2 is about 100 mm as in FIG. As a result, a space for hand washing is formed between the water supply port 12 and the drainage port 7. In this case, since the rim 5 is easily splashed with water, it is not necessary to wet the area around the cleaning ball 2. Note that FIG. 7 is a front view of the water supply device 1 of FIG. The water supply port 12 and the water discharge port 20 are located at the lowest position 5 of the rim 5.
The air gap is made higher than a. Also,
FIG. 8 is a side view of the water supply device 1 of FIG. In this case, the water discharge port 20 is formed in the boundary portion 8 between the water faucet 10 and the cleaning ball 2, and is a place where the user's eyes do not touch it.

Next, still another embodiment will be described with reference to FIGS. In the water supply device 1 shown in FIG. 9, the faucet exterior portion 11 of the faucet 10 includes a bridge 19
The water supply port 12 is provided in the center of the bridge 19. Further, the water discharge port 20 is provided in each of the bridge legs 19a in the faucet exterior part 11.
The bridge 19 can also be used as a handrail. 10. FIG. 10 is a front view of the water supply device 1 of FIG. The water supply port 12 and the water discharge port 20 are higher than the lowermost position 5a of the rim 5 to form an air gap. In addition, FIG. 11 is a side view of the water supply device 1 of FIG. 9. By welding the faucet exterior part 11 and the cleaning ball 2 to be integrally formed, a sense of unity can be provided, a novel design and usability can be provided, and the strength can be improved, so that it can also be used as a handrail. can do. The shape of the cleaning ball 2 is the same as the shape shown in FIG.
