Description

[Detailed explanation of the idea] The present invention relates to an improvement of a washbasin.

As shown in FIG. 1, a conventional washbasin 1 has an overflow hole 3 opened on the back side of an inner circumferential wall surface 2a forming a water storage basin 2. As shown in FIG. However, since the overflow hole 3 is within the visual field of the user, there is a drawback that the appearance of the washbasin 1 is impaired.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention aims to provide a washbasin in which an overflow hole is provided outside the user's visual field.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings. FIG. 2 is a plan view showing an embodiment of the washbasin 5 according to the present invention, FIGS. 3 to 6 are cross-sectional views of the same, and FIG. 7 is a cross-sectional perspective view of the same washbasin 5 viewed from above near the back. It is a diagram. The washbasin 5 is made of ceramic,
It is made of synthetic resin, metal, etc., and a water reservoir 6 is formed from a bank 7. The bank 7 has an upper surface 7a on its rear side.
A faucet mounting seat 7b is formed near the center, and faucet mounting holes 8, 8 are bored therein.
On both sides or one side of the faucet mounting seat 7b, a low upper surface portion 7c is formed which is lower than the maximum water storage level A of the bank 7 (see FIG. 5). The lower upper surface portion 7c may be used as a soap placing portion. An upright wall 9 is provided inwardly of the lower upper surface portion 7c along the longitudinal direction of the lower upper surface portion 7c. The height h of the standing wall 9 is 10 to 20 mm.
Although it is preferable to set it as , it is not limited to this numerical value in any way. Outer end 9a of the standing wall 9
is formed in a curved shape that gradually becomes lower toward the outside, and is formed so that the flow channel 10 communicating with the lower upper surface portion 7c and the water reservoir 6 is approximately at the same level as the lower upper surface portion 7c. . The lower upper surface portion 7c
An overflow hole 11 is formed in a location near the upright wall 9 of the washbasin 5 so as to be out of the user's field of vision when the washbasin 5 is installed at a normal usage height. The overflow hole 11 is connected to the embankment 7.
It communicates with a drainage channel 12 formed inside. A drain port 1 communicating with a drain channel 12 is provided at the bottom of the water storage pot 6.
3 is open. Although the washbasin 5 has a rectangular planar shape, it is not limited to this and is not shown in the drawings, but it is of course possible to have an appropriate shape such as a round planar shape or an elliptical planar shape. be.

FIG. 8 is a cross-sectional view showing another embodiment of the washbasin 5' according to the present invention, and the difference from the washbasin 5 shown in FIG. This is the point where a hole 11 is bored.

Next, the effects of the washbasin 5 according to the present invention will be explained. The washbasin 5 is attached and fixed to a wall surface or the like via a flange 5a. Further, in the washbasin 5, a standing faucet (not shown) is attached to the faucet mounting seat 7b, and a drain pipe (not shown) with a stop valve is connected to the drain port 13. Surplus water generated by continuously supplying water into the water storage pot 6 flows into the lower upper surface parts 7c, 7c from the water channels 10, 10, and then flows into the overflow hole 11, while cleaning the lower upper surface parts 7c, 7c.
11 and is discharged to a drain pipe via a drainage channel 12.

As detailed above, the washbasin according to the present invention has an overflow hole drilled outside the user's field of vision, so it has the practical effect of providing a beautiful washbasin that does not impair its appearance. has.
