Description

[Detailed description of the invention] This invention is used in low tank hand wash basins for flush toilets.
Regarding the mechanism for attaching the guide tube to the washbasin, the guide tube is installed horizontally so as to be parallel to the bottom surface of the washbasin.

In the conventional low tank for flush toilets, as shown in FIG.
Since it was configured to fall directly into the low tank F from the droplet E provided on the bottom of the wash basin A, especially when the water pressure is high, the washing water C splashing from the droplet E would make noise. The cleaning water C falls on the flat operating arm G that opens and closes the drain valve (not shown) of the low tank F, and the cleaning water C flows along the horizontal part of the operating arm G and enters the split groove I that pinches the base H. However, there was a further problem in that the water penetrated the inner peripheral surface of the handle shaft K and the bearing barrel along the pin J, and leaked out of the low tank F from the peripheral surface of the handle shaft.

Therefore, it is necessary to take troublesome measures to prevent water leakage, such as covering the horizontal portion of the operating arm G with a waterproof cover (not shown).

The purpose of this invention is to solve the above-mentioned drawbacks, to prevent the washing water that falls from the wash basin into the low tank from scattering, and at the same time to prevent the wash water from flowing back into the wash basin.

The basic structure of this device is that the fitting part at one end of the guide tube is inserted into the base hole in the bottom hole of the wash basin so that the guide tube for washing water is arranged almost parallel to the bottom surface of the wash basin. Alternatively, it may be attached via a fastener.

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

The cleaning water guide tube 1 is made of rubber, synthetic resin, or other material, so it is shaped into a nearly rectangular shape with an annular concave and convex fitting part 2 bent at approximately 90 degrees at one end, and a bellows section 3 at the other end. A discharge port 4 is provided.

The cap 5 has a cylindrical shape made of rubber, synthetic resin, etc., and is provided with a flange 9 on one end surface having drainers 8, 8 for removing all residual water from the bottom surface 7 of the hand wash basin 6, which will be described later. A protrusion 11 that elastically presses against the inner peripheral surface of the bottom hole 10 of the container 6
The guide tube 1 is provided with an insertion part 12 made of annular irregularities into which the fitting part 2 of the guide tube 1 is inserted, and a wash water passage hole 13 is provided inside, and the insertion part 12 is inserted into the bottom hole 10.

The washbasin 6 is a normal one, and the low tank 14 is for a flush toilet.
It is supported by stacking it on top of the.

FIGS. 5A to 5C show another embodiment, in which a guide tube 1' shown at port 49 is made of rubber, synthetic resin, or the like and is formed into a similar shape, and is inserted into the bottom hole 10 to form a curved pipe portion 15. A flange 9' is provided at the open end, and this guide tube 1' is inserted into the bottom hole 10 of the washbasin 6 from the outlet 4 thereof, and a cross section is formed to define the guide tube 1' in the bottom hole 10. A polygonal backing type fastener 16 is fitted into the guide tube 1' from the discharge port 4 side and pressed against the lower part of the bottom hole 10, and the guide tube 1' is fixed to the bottom hole by this fastener 16 and the flange 9'. Fix it at 10.

Next, in the same manner as shown in FIG. 5C, an O-ring-shaped fastener 17 is inserted into the guide tube 1' instead of the fastener 16 for the 9-hole type. Fastener 1
8 to fix it.

In addition, the one shown in Figure 5
9, and the legs 19 are connected to the bottom hole 10 and the guide tube 1'.
A fastener 20 with legs is provided which is press-fitted and fixed between the bent pipe portion 15 of the present invention.

In this invention, after using the toilet, the handle 21 shown in FIG.
When the drain valve 22 is operated, the drain valve 22 is opened as usual, and the ball tap 23 is activated by discharging a predetermined amount of cleaning water, thereby supplying water to the low tank 14 and simultaneously discharging the cleaning water from the discharge pipe 24.

This washing water flows through the bottom hole 1 in the low central part of the bottom surface 7 of the washbasin 6.
The flow flows into the guide tube 1 through the through hole 13 of the cap 5 fitted to the guide tube 1, and collides with the wall surface of the low tank 14 through the discharge port 4 of the guide tube 1, causing the discharge port 4 to approach the wall surface of the low tank 14. and falls into the low tank 14 without making any noise.

At this time, all remaining water on the bottom surface 7 of the washbasin 6 falls into the through hole 13 through drainers 8, 8 as indicated by the arrows in FIG.

The same effect also applies to other embodiments of the guide tube 1'.

Since this invention has the above-described configuration, it has the following advantages.

(1) Since the wash water from the hand wash basin is discharged through the guide tube installed horizontally along the bottom of the wash basin, it is possible to prevent the wash water from scattering into the low tank.

(2) Since the bottom hole of the washbasin and the fitting portion of the guide tube are attached via a base or a fastener, the number of steps required for attaching the guide tube can be halved.

(3) In particular, even when the rotor tongue is installed with the rotor tilted forward, the cleaning water does not scatter, so there is no water leakage along the handle shaft, and there is no noise when the rotor falls.

(4) Since the guide cylinder is installed horizontally at a position higher than the full water level of the low tank, the washing water in the low tank will not flow back into the hand wash basin.

(5) Furthermore, since a drainer is provided on the base, it is possible to reliably prevent ice from forming on the bottom of the washbasin, especially in cold regions.
