Abstract

PROBLEM TO BE SOLVED: To enhance serviceability by setting the height from a floor surface of a wall urinal to the lower edge of an upper end wall to a specific value and setting the height from the floor surface to the upper edge of a lip to a specific value as well. SOLUTION: A ball area 2 is formed over an area from the upper end of a main body 1 of a urinal to the lower end. An upper wall 3, which is slightly projected forward, is formed on the upper end of the main body 1 in such a fashion that it may cover the ball area 2. A side wall 4, which is more projected than the upper wall 3, is formed on both ends of the main body 1. The bottom of the ball area 2 is formed in communication with the lower end of the side wall 4, thereby forming a lip area 5 which is projected forward. Furthermore, the height H from a floor surface 51 to the lower edge of the upper wall 3 is set to 900 to 1100mm and the height (h) from the floor surface 51 to the upper edge of the lip area 5 is set to 260 to 400mm. A urinal is provided on the floor surface 51. Therefore, this construction is well serviceable for both adults and children.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted urinal, and more particularly to a urinal that is easy for children and adults to use.

[0002]

2. Description of the Related Art In wall-mounted urinals, the height of the lip portion protruding from the main body is determined by the installation height of each urinal. For this reason, generally, construction is performed according to the height of an adult, but in a public toilet, for example, the installation height is often changed so that children can use it. In addition, floor-standing type and urinals exclusively for infants have been installed as necessary so that infants and children can use them without stretching their backs.

On the other hand, in public toilets in particular, an automatic cleaning system is often employed which is equipped with a photoelectric sensor for detecting a user and automatically supplies cleaning water to the urinal after small use. In this case, the sensor is generally installed on the wall directly above the urinal, or as a facility provided on an obliquely lower wall of the toilet body as described in JP-A-4-272338. In addition, instead of being incorporated in the wall, there is a device which is arranged at the upper end of the toilet body as described in, for example, Japanese Patent Laid-Open No. 1-282428.

[0004]

[Problems to be Solved by the Invention] For example, even if a urinal designed for adults is to be installed at a low height,
Even children can use it comfortably. However, the bowl of the toilet bowl is too low for adults and tall people, which causes usability. As described above, it is not always preferable from the viewpoint of usability to use the toilet bowl together for adults and children by simply changing the installation height.

Further, if a general-purpose urinal is installed low for children, it will be different from other urinals in the case of public use, resulting in poor appearance.

Further, in the case of an automatic toilet bowl cleaning system, if the sensor is incorporated in the upper end of the toilet body or the wall just above it,
The height of a child or infant falls outside the detection range of this sensor, and the automatic cleaning system does not function effectively. On the other hand, in the case where the sensor is incorporated in the wall obliquely below the toilet body as in the above-mentioned Japanese Patent Laid-Open No. 4-272338, it is possible to detect the foot of the user, which is related to the height of the user. Without a sensor, detection is possible.

However, since the sensor is separate from the toilet body, there is a risk that the user's feet will have a lower detection rate due to installation errors of the toilet body and the sensor, incorrect setting of the attitude of the sensor, etc. during construction. There is. Therefore, the detection failure by the sensor is unavoidable and may affect the automatic cleaning system.

In the present invention, the problem to be solved is to provide a urinal which can be easily used by both adults and children, and whose operation is ensured in the one provided with the automatic urinal cleaning system.

[0009]

According to the present invention, there is provided an upper end wall overlying a ball portion of a main body, and a drip receiving lip portion which forms a lower end portion of the ball portion and protrudes forward. A wall-mounted urinal for fixing the lower end of the main body to a wall apart from the floor of the installation part, wherein the height from the floor to the lower edge of the upper wall is 900 to 1100 mm, and the height from the floor is Height to the upper edge of the lip is 260-40
It is characterized by being installed as 0 mm.

In such a structure, a water supply system for automatically supplying wash water to the ball portion of the main body is provided, and the water supply system is driven on the lower surface of the lip portion of the main body or below the lip portion by sensing the presence of the user. It is possible to provide a sensing unit for causing the above. In this case, the sensing portion may be provided at a portion below the outer contour of the bottom surface of the ball portion and covering the wall.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The height of the lip portion is set to 260 to 400.
By setting it to mm, it is possible to adapt to the height of children of the age who can make small use by themselves, and even adults can use it as a stall type urinal, for example, and the lower edge of the upper wall Up to 900-1100m
By setting m, even a tall person can be used without leaning forward.

Further, if the sensing portion is provided on the lower surface of the lip portion or below the lip portion, the user's feet are sensed, so that the user can be sensed regardless of height and height, and the ball portion of the ball portion can be sensed at each use. Cleans reliably.

Further, when the sensing portion is provided below the outer contour of the bottom surface of the ball portion and over the wall, the sensing portion is provided by the ball portion forming the lip portion projecting to the front side. It can be a hidden construction body.

1 is a front view of a urinal of the present invention, FIG. 2 is a plan view, and FIG. 3 is a vertical sectional view taken along the line AA of FIG.

In the figure, the body 1 of the urinal is supported by a dedicated hanger (not shown) with its back surface abutted against a wall 50, and is fixed at a predetermined height from a floor 51.

The main body 1 has a vertically elongated ball portion 2 formed from its upper end portion to its lower end portion, and an upper wall 3 projecting slightly forward so as to cover the ball portion 2 is provided at the upper end portion, and both left and right ends are provided. The side wall 4 is formed so as to protrude in front of the upper wall 3. Then, the ball portion 2 continues to the lower end of the side wall 4.
It has a lip portion 5 which forms a bottom face portion of the above and which has a substantially triangular planar outer shape on the front side.

A drainage channel 2a is formed in the vertical direction on the bottom side of the ball portion 2 and a substantially U-shaped trap 2c is formed between the drainage channel 2a and the discharge port 2b opened on the back surface. . Then, on the left and right of the outer wall 2d forming the trap 2c from the drainage channel 2a, there are provided flanges 6 covering the entire surface of the wall 50. A drain pipe (not shown) provided in the wall 50 is connected to the outlet 2b.

The flange 6 is formed symmetrically across the outer wall 2d and has a quadrangular front shape.
The left side incorporates a sensing unit 7 for sensing the user's feet for automatic cleaning. The sensing unit 7 is a reflection type infrared sensor that has been conventionally used in an automatic cleaning system, and is capable of inputting to a controller a signal that senses that the user has left.
Then, the controller controls to open the solenoid valve (not shown) in the water supply pipe to the water discharge port 2e provided at the center of the upper end of the ball unit 2, so that the cleaning is automatically performed after the small use. Water can be supplied to the ball portion 2.

The controller may be incorporated in the main body 1 or may be provided as a central control panel for controlling the solenoid valve of the water supply pipe to each of the urinals in a facility where a large number of urinals are arranged. .

The bottom wall 1a on the lower end side of the ball portion 2 and facing the flange 6 is formed as an inclined surface whose front side rises upward as shown in FIG. FIG. 4 is a schematic perspective view of an essential part for showing the positional relationship between the bottom wall 1a and the sensing part 7. The light projecting window 7a and the light receiving window 7 of the sensing part 7 are shown in FIG.
The sensing unit 7 can be positioned so that the visual field in front of b is wide open.

The sensing section 7 may be provided on the right flange 6 when viewed from the front, or may be provided on the lower surface of the bottom wall 1a or the front surface of the outer wall 2d. In any of these arrangements of the sensing unit 7, the projection window 7 of the sensing unit 7
It suffices to incorporate them so that a and the light receiving window 7b are in a posture of facing the front.

Here, when determining the installation height of the body 1 of the urinal, it is preferable to set the height when the user can finish the urination in the case of installing it for public use. Considering the height of the child of this age, the preferable value of the height h from the floor 51 to the lip portion 5 (see FIG. 3) is about 260 to 400 mm.

Further consideration for such a range of installation height is that a sufficient depth of the lip portion 5 is ensured to prevent urine from splashing outside, and that the urinal is secured. The point is to pay attention to the buried position of the wall drainage pipe (not shown) from the floor 51 so that it can be installed at. That is, the above-mentioned installation height range of 260 to 400 mm is based on only the height of the child, but in order to ensure that it can be installed hygienically and reliably as public facilities, it prevents splashing of small water. If the buried position of the wall drain pipe and the wall is added to the installation conditions, the lip
It is preferable to set the lower limit of the height to 260 mm.

Even if the lip portion 5 is set to be low in this way, it has the same usability as that of a stall type urinal, so that even an adult or a tall person can use it without any trouble. If the height of the ball 2 is too low for an adult or a person of height, the player will take a forward bending posture, so that the height H from the floor 51 to the lower edge of the upper wall 3 (Fig. Three
(Reference) is set in the range of 900 to 1100 mm. If the height up to the upper wall 3 is set, the height is 180
Even a person with a size of about cm does not need to lean forward and can be used easily.

When a person stands in front of the body 1 of the urinal, the left foot of the person is positioned in front of the sensing section 7. Therefore, for example, when the sensing unit 7 is provided at the upper end of the main body 1, there is a possibility that the body cannot be sensed when used by a child. All users can be reliably detected regardless of. Therefore, the cleaning of the ball portion 2 is always performed by the automatic toilet cleaning system, and clean equipment is always maintained even when used for public use.

Since the sensing unit 7 is incorporated in the flange 6 which is a part of the main body 1, the positional relationship between the sensing unit 7 and the main body 1 is fixed. Thus, for example, the wall 5
When the sensing unit 7 is provided separately from the main body 1 in 0, the sensing range of the sensing unit 7 may fluctuate due to a construction error or the like as described in the section of the prior art, but such a trouble is accompanied. Absent. Therefore, the user can be surely detected to operate the automatic toilet bowl cleaning system, and the malfunction can be prevented. The protrusion of the lip part 5 to the front side makes the sensing part 7 completely invisible from the upper side, improving the appearance and making it difficult for the general user to notice its existence, so that it may be used unnecessarily. Nor.

[0027]

According to the present invention, by setting the height of the lip portion and the height of the upper end wall, the equipment can be used by both adults and children, and it is necessary to change the mounting height of the urinal depending on the site. In addition to enabling simple construction, it is possible to arrange all the urinals at the same height in a system where many urinals are arranged, and the appearance of the equipment is also improved.

Further, by arranging the sensing portion on the lower surface of the lip portion or below the lip portion, it is possible to sense the user's feet, so that the sensing is possible regardless of the height of the user, and Assures automatic cleaning,
A hygienic environment can always be maintained for public use.

Further, if the sensing portion is provided in a portion that covers the wall below the outer contour of the bottom surface of the ball portion, the sensing portion is hidden by the lip portion projecting to the front side, so that the appearance is improved and the sensing is performed. Since a person does not touch the part unnecessarily, a construction body that also serves as a protective measure can be obtained.
