Description

[Detailed description of the invention] This invention relates to a washbasin installed in a toilet or the like.

Generally, a ceramic hand basin is installed inside the toilet for washing hands, but because the space in the toilet is small, such hand basins are smaller than the wash basin (stand). There is. Then, limescale in the running water and dust in the air adhere to the water collection recesses of such hand wash basins, resulting in brown or black stains and dirt. However, since the hand wash basin is small as mentioned above, it is difficult to remove such stains and dirt even by cleaning, and as a result, there is a problem in that the user feels unclean.

The purpose of this invention is to prevent stains and dirt from adhering to the wash basin and to give the user a sense of cleanliness.

Such a purpose is to provide a wash basin in which water from a water inlet is collected in a water collecting recess formed on the upper surface and flows out from a hole formed in the deepest part of the water collecting recess. This can be achieved by providing a cover that covers and tightly contacts the water recess and has an opening communicating with the hole.

An embodiment of this invention will be described below with reference to the drawings.

Figures 1 and 2 show an example in which this invention is applied to a low tank. In the figure, reference numeral 1 denotes a ceramic low tank having a triangular prism shape as a whole, and this low tank 1 has a tank body 2 that is open at the top. Water for washing is temporarily stored inside this tank body 2. A wash basin 3 which also functions as a lid is placed on the tank body 2, and this wash basin 3 closes the upper opening of the tank body 2. A substantially triangular water collection recess 4 is formed on the upper surface of the washbasin 3, and the water collection recess 4 becomes deeper as it approaches the center. Water collection recess 4
A penetrating hole 5 is formed in the deepest part of the hole 5.
The water collected through the tank flows out and falls into the tank body 2. Reference numeral 6 denotes a water injection pipe attached to a corner of the washbasin 3, and water is injected toward the water collection recess 4 from the tip of the water injection pipe 6, that is, the water injection port. 7 is a supply pipe connected to the water injection pipe 6, and between the supply pipe 7 and the water injection pipe 6 is a valve (not shown) that closes when the tank body 2 is full and opens when the water decreases. It is provided. A cover 8 is fitted onto the washbasin 3 from above, and the cover 8 is made of a synthetic resin with low rigidity, such as nylon or vinyl. This cover 8 has approximately the same thickness, and various patterns are printed on the surface to make decorations and dirt less visible.
The cover 8 has an upper surface portion 9 that covers the water collection recess 4 and comes into close contact with it, and a side surface portion 10 that extends downward from the periphery of the upper surface portion 9. Top part 9 of cover 8
A through hole 11 through which the water injection pipe 6 passes and an opening 12 communicating with the hole 5 are formed in the hole 5 . A ring-shaped protrusion 13 is formed around this opening 12 to be fitted into the hole 5. Further, the side surface portion 10 of the cover 8 is inclined inwardly as it moves downward.

Next, the operation of one embodiment of this invention will be explained.

First, when attaching the cover 8 to the wash basin 3, the water injection pipe 6 is passed through the through hole 11, and then the cover 8 is fitted to the wash basin 3. At this time, cover 8
Since the side surface portion 10 of is inclined as described above,
The lower end portion of the side surface portion 10 is pushed apart, and a moment is applied to the upper surface portion 9 in the direction of arrow A in FIG. Moreover, since the protrusion 13 is pushed into the hole 5, the upper surface part 9 of the cover 8 is pressed against the water collecting recess 4 and is securely in close contact with the water collection recess 4, thereby preventing the generation of a gap therebetween. In addition, when the cover 8 is attached to the washbasin 3, the side surface 10 and the protrusion 13 of the cover 8 are
is in close contact with the vertical surface of the washbasin 3, so water will not enter between the cover 8 and the washbasin 3.
Next, in this state, when a lever (not shown) is rotated to use the water in the tank body 2 for flushing, the valve opens and water is injected from the water inlet toward the surface of the cover 8. After this injected water is used for washing hands, it is collected by the upper surface 9 of the cover 8, that is, by the water collection recess 4 of the washbasin 3, and is passed through the opening 12 and the hole 5 into the tank body. 2 and is temporarily stored. When such an operation is performed many times and a long period of time elapses, limescale contained in the water and dust in the air adhere to the surface of the upper surface portion 9 of the cover 8, resulting in brown or black stains and dirt. However, if the dirty cover 8 is removed from the washbasin 3 before it loses its cleanliness and a new cover is attached, the washbasin 3 itself can be kept clean without soiling it. and,
If the pattern on the surface of the cover 8 is bright and clean, the interior of the toilet will be bright and clean.

FIG. 3 shows another embodiment of this invention, and this embodiment is an example in which this invention is applied to a low tank having a square box shape as a whole. In this embodiment, the cover 15 has a generally rectangular shape.
Note that the other configurations and operations are the same as those of the previous embodiment.

In the above-mentioned embodiment, the case where this invention was applied to a low tank was explained, but it can also be applied to a small hand wash basin installed in a toilet or the like.

As explained above, according to this invention, a cover is provided that covers and tightly contacts the water collection recess and has an opening that communicates with the hole, which prevents stains and dirt from adhering to the washbasin and prevents it from being used. It can give people a sense of cleanliness.
