Abstract

(57) [Summary] [Purpose] To discharge water from a nozzle head to a sufficiently wide area so that the tank can be washed quickly and reliably. [Structure] A nozzle head that discharges water in a direction along the inner peripheral wall of the tank is provided so as to project from the inner peripheral wall, and the direction of water discharge from the nozzle head is in a range directed downward and to the left and right.
Further, the opening area of the water discharge end of the nozzle head is made larger on the side facing in the left-right direction than on the lower side. The opening area at the discharge end of the nozzle head is larger on the side facing in the left-right direction than on the part facing downward, so the amount of water discharged from the part with a large opening area increases in the circumferential direction of the tank. The diffusion of water is promoted, and the inner peripheral wall of the tank is cleaned over a wide area.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nozzle device for spraying washing water along a wall of a bowl or a tank in equipment such as a washbasin of a vanity or a hair washer equipped with a bowl and a tank.

[0002]

[Prior Art]

 After washing the face or brushing the teeth with a washbasin, the residue of soapmeal or toothpaste is likely to adhere to the wall of the ball, and with a hairwasher, hair or shampoo tends to remain in the ball. For this reason, after use, the ball is flushed with water to wash off these deposits by hand.

Such work is not only troublesome, it is not preferable from the viewpoint of hygiene, and since it depends on manual work, sufficient cleaning cannot be performed.

On the other hand, equipment has also been used in the past, in which a nozzle is provided on the ball to flush cleaning water along the inner wall of the ball and the ball is cleaned by this nozzle. An example thereof is that disclosed in Japanese Utility Model Publication No. 55-30379.

This is because a plurality of nozzle heads are provided on the upper wall of the ball, the nozzle head has a flat shape, and water can be jetted over a wide range so that not only the lower surface but also the lower half of the side surface. The ejection hole is incised up to the part up to. With such ejection holes, water can be washed off in a wide range, the cleaning range of the ball can be expanded, and the deposits can be washed off quickly.

[0006]

[Problems to be solved by the device]

 However, the openings of the ejection holes are slit-shaped with the same opening cross-section on both the lower surface side and the side surface of the nozzle head. Therefore, the water supplied to the nozzle head is discharged at almost the same flow velocity and flow rate from any position of the ejection hole. Therefore, washing with water directly below the nozzle head is sufficient, but the diffusion of water discharged from the side surface is the same as the amount of water flowing directly below, so sufficient diffusion in the lateral direction cannot be achieved.

As described above, even if the ejection holes capable of discharging water in a wide range are provided, the amount of water that tends to flow downward tends to increase due to the influence of gravity. If the flow velocity is similar to that on the lower surface side, the area that diffuses laterally tends to be small. For this reason, it is not possible to sufficiently wash the wall of the part where the ball stands up, so that the deposit ends up leaving behind.

The problem to be solved in the present invention is to discharge the water from the nozzle head to a sufficiently wide range so that the tank can be quickly and surely cleaned.

[0009]

[Means for Solving the Problems]

 The present invention provides a nozzle device in which a nozzle head that discharges water in a direction along the inner peripheral wall of a tank is provided so as to project from the inner peripheral wall, and the direction of water discharge from the nozzle head is in a range extending downward and leftward and rightward. The opening area of the water discharge end of the nozzle head is larger on the side facing in the left-right direction than on the lower side.

[0010]

[Action]

 The opening area at the discharge end of the nozzle head is larger on the side facing in the left-right direction than on the part facing downward, so when water is supplied, the downward flow is throttled and discharged from the part with a large opening area. The amount of water that can be consumed increases. Therefore, the amount of water flowing to the side can be increased, and the inner peripheral wall of the tank can be washed in a wide range.

【Example】

 FIG. 1 is a plan view showing a toothbrushing ball provided with the nozzle device of the present invention, and FIG. 2 is a side vertical sectional view thereof.

In the figure, the main body 1 of the ball is assembled and installed in a counter (not shown), and a ball portion 1a occupying substantially the front half is formed in a trough shape. Stepped guide rims 1b are provided on the left and right of the inner peripheral wall of the ball 1a, and a drain port 1c for connecting to a drain pipe (not shown) is opened at the bottom. The guide rim 1b has a cross-sectional shape slightly protruding from the inner peripheral wall of the ball portion 1a toward the center side, and is inclined obliquely toward the front end side as shown in FIG.

A water faucet 2 for brushing teeth is provided upright on the back side of the ball portion 1a, and a water faucet 3 for cleaning the ball portion 1a is incorporated. Both the faucet 2 and the cleaning faucet 3 are connected to a common water supply pipe (not shown).

A nozzle head 4 located at the innermost center of the ball portion 1 a is connected to the cleaning faucet 3 by a supply pipe 5, and by operating the cleaning faucet 3, cleaning water is washed from the nozzle head 4 to the ball 1 a. Pour off.

FIG. 3 is a vertical cross-sectional view of essential parts showing details of the cleaning faucet 3 and the nozzle head 4. For the sake of explanation, the positional relationship between the cleaning faucet 3 and the nozzle head 4 is different from that shown in FIG.

The cleaning faucet 3 is of a self-closing faucet type that is fixed by penetrating a mounting hole 1d formed in the main body 1. In FIG. 3, a valve chamber 3b connected to the water supply pipe is formed at the lower end of the faucet body 3a, and an operating handle 3c is provided at the upper end. A cylinder 3d is provided in the valve chamber 3b, and a valve body 3e is built in the inside of the cylinder 3d in a sliding manner, and a space inside the cylinder 3d under the valve body 3e serves as a pressure chamber 3f. A pressure reducing plate 3g having a small hole is provided at the lower end of the pressure chamber 3f, and the valve chamber 3b and the pressure chamber 3f are communicated with each other through the small hole.

A valve hole 3h is opened at the upper end of the cylinder 3d, and the lower surface around the valve hole 3h is used as a seating surface for the valve element 3e, and the valve element 3e projects from the valve hole 3h and faces the secondary chamber 3i. The pusher block 3j is integrated. The pusher block 3j has a hole 3k formed in the axial direction, and the rod portion of the pilot valve body 3m is inserted into the hole 3k to hold the same movably in the axial direction. The lower end of the valve seat 3n receives the pilot valve body 3m. To provide. Further, a coil spring 3p is incorporated between the lower end of the pilot valve body 3m and the member holding the pressure reducing plate 3g.

On the other hand, the handle 3c is connected to a main spindle 3q and a sub-spindle 3r whose axial position is self-adjusting, and the main spindle 3q is attached to the upper side by a spring 3s incorporated in the faucet body 3a. Urge to. The sub-spindle 3r is arranged so that its lower end is brought close to the pusher block 3j and the upper end of the rod of the pilot valve body 3m.

In such a water faucet 3 for cleaning, when the handle 3c is pushed, the lower end of the auxiliary spindle 3r first pushes the upper end of the rod of the pilot valve body 3m and separates it from the valve seat 3n. As a result, the water in the pressure chamber 3f is discharged from the small hole of the pressure reducing plate 3g to the valve chamber 3b, and at the same time, is discharged from the hole 3k of the pusher block 3j to the secondary chamber 3i.

Further, when the handle 3c is pushed down, the lower end of the auxiliary spindle 3r pushes down the pusher block 3j, and the valve body 3e separates from the seating surface around the valve hole 3h and opens the valve. As a result, water is supplied from the inflow hole 3d-1 formed in the peripheral wall of the cylinder 3d, and is supplied from the valve hole 3h to the secondary chamber 3i. Then, this water supply is sent to the nozzle head 4 via the supply pipe 5.

When the handle 3c is once pushed down and released, a small amount of water flows into the pressure chamber 3f through the small holes of the pressure reducing plate 3g. As a result, the valve body 3e and the pilot valve body 3m gradually rise due to the water pressure received in the pressure chamber 3f, and after a certain period of time, these valve body 3e and the pilot 3m close their respective flow paths and close them. Speak.

As described above, the cleaning faucet 3 can automatically supply a fixed amount of water and stop it by simply pressing the handle 3c. Therefore, when cleaning the ball portion 1a, the person can leave the place immediately after pushing the handle 3c, and it is not necessary to perform the water-stop operation.

As shown in FIG. 3, the nozzle head 4 to be supplied with water from the water faucet 3 for cleaning has a T-shaped main body 4a connected to a supply pipe 5 by a joint 5a and a cover 4b fixed to the front surface thereof with screws 4c. With.

FIG. 4 shows the details of the main body 4 a. FIG. 4A is a vertical sectional view taken along a plane including an axis, FIG. 4B is a front view, and FIG. 4C is the same. It is a sectional view taken along the line AA of FIG.

The main body 4a has an internal flow path connecting to the supply pipe 5 in a sleeve portion 4e having a male screw 4d cut on the back side, and a flange 4f provided at the front end. A screw hole 4g for passing the screw 4c is formed in the flange 4f, and a guide flange 4h having a larger outer diameter is formed in the lower half. A deformable slit 4i having a central angle of 180 degrees is provided between the guide flange 4h and the front flange 4f.

FIG. 5 shows the details of the cover 4b. FIG. 5A is a vertical sectional view, FIG. 5B is a bottom view, and FIG. 5C is a rear view.

The cover 4b has a female screw hole 4j into which a screw 4c is screwed at the center of its back, and has a shape in which the lower half of the back end is slightly shaved. Then, on the back surface of the lower half of the cover 4b, a protrusion 4k slightly protruding in the back direction is formed in an inferior arc shape.

FIG. 6 is a bottom view of the nozzle head 4, and FIG. 7 is a perspective view of the nozzle head 4 as viewed from the bottom side.

When the cover 4b is connected to the main body 4a, the internal passage of the sleeve 4e of the main body 4a is opened toward the ball portion 1a by the slit 4i as shown in FIG. Then, as shown in FIGS. 6 and 7, by connecting the cover 4b, the back side of the cover 4b overlaps the front surface of the edge of the guide flange 4h. At this time, the ridge 4k is provided on the back of the cover 4b so as to cover the portion directly below the guide flange 4h. Therefore, the opening area of the gap 6 between the portion corresponding to the protrusion 4k and the guide flange 4h is small, and the gap 7 formed on both the left and right sides thereof up to the upper end of the guide flange 4h is located directly below. It becomes larger than the opening area of the gap 6.

In the above structure, when the handle 3c of the water faucet 3 for cleaning is pushed, water is sent from the supply pipe 5 to the nozzle head 4, passes through the sleeve 4e and the slit 4i of the main body 4a, and then the guide flange 4h and the cover 4b. Water is discharged from the gaps 6 and 7. At this time, the flow path area of the water discharge end of the nozzle head 4 has a small surface on the side facing directly downward, and a large surface on the left and right sides to the opening end in a substantially horizontal posture. That is, the amount of water passing through the gap 6 on the small side is reduced more than the area of the flow path toward the gap 7 on the large side, and passes through the gap 7 compared to the amount of water flowing down. The amount of water that jumps out to the side increases. Therefore, when the flow path area at the discharge end was made uniform as in the conventional case, the amount of wash water discharged to the side was smaller than the amount discharged downward, whereas the amount of wash water discharged to the side was large. Can be diffused. Therefore, the cleaning area is enlarged, and the entire inner peripheral wall of the ball portion 1a can be quickly cleaned by providing only one nozzle head 4.

FIG. 8 is a bottom view showing another embodiment of the nozzle head 4, and FIG. 9 is a vertical sectional view taken along the line BB of FIG. The same members as those in the above example are designated by the common reference numerals, and the description thereof will be omitted.

Also in this example, similarly to the above example, between the guide flange 4h at the tip of the main body 4a and the back surface of the cover 4b, a gap 6 having a small opening area is formed on the side facing downward, and the left and right sides thereof are formed. Is a gap 7 having a large opening area. Therefore, at the time of water supply, a large amount of water is vigorously discharged laterally from the gap 7, and the inner peripheral wall of the ball portion 1a can be efficiently washed over a wide range.

FIG. 10 shows another embodiment of the nozzle head 4, which has a configuration in which the flow passage area is gradually increased from the portion directly below the main body 4a to the side.

In (a) of the figure, with respect to the guide flange 4h of the main body 4a of the nozzle head 4, the back portion of the cover 4b has a shape which is linearly inclined from its lower end to a region having a central angle of 180 degrees. .. Due to this inclination, it is possible to provide a gap 8 between the guide flange 4h and the cover 4b which linearly increases in proportion to the opening area toward the upper side.

Even in the gap 8 in which the opening area gradually increases toward the side as described above, the amount of water discharged to the side can be increased more than the amount of water flowing directly below, and similarly, the ball portion It is possible to wash 1a in a wide range at once.

Further, (b) of the figure is an example in which the back portion of the cover 4b is formed in a curved shape, and the increase rate of the opening degree is increased as the clearance 9 with the guide flange 4h is directed to the side. .. By providing such a gap 9, the rate of change in the flow rate of water discharged laterally can be changed more greatly than in the case of (a) in the figure, and the amount of water discharged from the uppermost side can be maximized. Therefore, it is effective for cleaning when the fluid flows down along the inner peripheral wall of the ball portion 1a after being discharged.

Although the toothbrushing ball has been described in the embodiment, it is needless to say that the nozzle device of the present invention can be applied to a washbasin, a hair washer, a sink, and other various tanks instead. ..

[0038]

[Effect of the device]

 In the present invention, the amount of water discharged laterally from the nozzle head can be made larger than the amount of water discharged downward, so that the discharged water can be diffused over a wide portion of the inner wall of the tank. For this reason, compared to the conventional nozzle having a uniform opening area, the inner surface of the tank in a wider range can be washed away at once, and efficient and reliable cleaning can be performed without wasting water.
