Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a low-basin hand-washing pot for supplying flush water to a toilet bowl, and more particularly to a hand-washing pot provided with a water discharge fitting. More specifically, it relates to a low tank hand-washing pot with an expanded effective use area of the pot surface.

[Prior Art] It is well known that a water spout is provided in a hand-washing pot fitted to the upper opening of a low tank, and the hand is washed with water discharged from the spout.

In this hand washing bowl, an inverted J-shaped tubular water discharge fitting is provided upright on the back side of the bowl surface. This water discharge fitting has a male screw shaft projecting from the base end side, the male screw shaft is inserted into the mounting hole formed in the hand washing bowl, and fixed to the hand washing bowl by tightening the nut on the male screw shaft. To be done.

[Problems to be solved by the invention] In such a fixing structure of the water discharge fitting, since the water discharge fitting is erected at a portion relatively close to the center of the bowl surface, the area of the bowl surface where the hands can be washed (Hereinafter, it may be referred to as an effective use area.) It becomes small, and there is a problem that water is easily scattered during hand washing.

[Means for Solving the Problem] The hand-washing pot for a low tank according to claim 1 is a hand-washing pot to which a water discharge fitting is attached and which is capped on the top of the low tank.
An upright wall is provided at the rear of the handwash bowl, and a water discharge fitting is attached to the upright wall.

According to a second aspect of the present invention, there is provided a low tank hand-washing pot according to the first aspect, wherein the water discharge fitting is provided with a male screw shaft penetrating a standing wall, and a water inlet is opened on a side surface of the male screw shaft.
It is characterized in that a water supply pipe member externally fitted to the male screw shaft and communicating with the inflow port is extended downward along the back surface of the standing wall.

[Operation] In the low tank hand-washing pot according to claim 1, since the water discharge fitting is attached to the standing wall, the effective use area of the pot surface is large. For this reason, it is easy to wash the hands and less water is scattered.
Further, since the standing wall is provided at the rear portion, the splash of water to the rear is reliably prevented.

According to the second aspect, the length of the metal fitting projecting rearward from the standing wall is shortened.

Embodiments Embodiments will be described below with reference to the drawings.

FIG. 1 is a perspective view of a hand-washing pot of a low tank according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the same, FIG. 3 is an enlarged view of an essential part of FIG. 2, and FIG. 4 is a perspective view of a connecting pipe. is there.

First, the overall configuration of the hand washing bowl 1 will be described with reference to FIGS. 1 and 2. Reference numeral 2 indicates a bowl surface. This bowl surface 2
The drainage port 3 is provided at the lowest level of the. A standing wall 4 is erected on the back side of the bowl surface 2. In this embodiment, the left and right ends of the standing wall 4 are connected to the side walls 5 and 6, and the side walls 5 and 6 are gradually lowered toward the front of the bowl surface 2. A water discharge fitting 7 is attached to the standing wall 4.

In the low tank handwash bowl configured in this way,
Since the water discharge fitting 7 is provided on the standing wall 4, the entire bowl surface 2 can be used for hand washing. Therefore, the effective use area of the bowl surface 2 is large, and splashing of water during hand washing is prevented.
Further, since the standing wall 4 is provided, it is possible to reliably prevent the water from splashing to the rear of the handwash bowl 1. Further, since the side walls 5 and 6 are provided, it is possible to prevent water from splashing to the side of the hand washing bowl.

As clearly shown in FIG. 3, the water discharge fitting 7 includes a main body 8 projecting forward of the standing wall 4 and a male screw shaft 9 projecting from a rear end of the main body 8. Reference numeral 10 is a spout.

The male screw shaft 9 has a tubular shape with the rear end surface 9a sealed,
A male screw shaft 9b is engraved on the outer periphery near the rear end surface 9a. An inflow port 11 is opened on the side surface of the male screw shaft 9. A head portion 13 of a water supply pipe member 12 is externally fitted to the male screw shaft 9.

As shown in FIG. 4, the head portion 13 has a short tubular shape and has flange portions 13a and 13b on both end surfaces. The water supply pipe member 12 includes a connecting pipe 14 integrally connected to the head portion 13, and the inside of the head portion 13 and the inside of the connecting pipe 14 are connected to each other through an opening 15.

As shown in FIG. 3, the water discharge fitting 7 is fixed to the standing wall 4 by fitting the head portion 13 onto the male screw shaft 9 and tightening the nut 17 via the washer 16. Further, the water supply pipe member 12 is fixed by tightening the nut 17. In this fixed state, the opening 15 and the inflow port 11 communicate with each other. Connecting pipe
The lower end of 14 is fitted and connected to a connecting pipe from a ball tap (not shown), and water is introduced from this connecting pipe.

Recessed grooves 18 and 19 are formed on both sides of the inflow port 11, and O-rings 20 and 21 inserted into the recessed grooves 18 and 19 seal water around the inflow port 11 and the opening 15. Is being carried out.

According to such a connecting structure of the water supply pipe member 12 to the water discharge fitting 7, the connecting pipe 14 is arranged close to the back surface of the standing wall 4. For this reason, the length of the metal fitting projecting to the rear of the standing wall 4 is extremely short, and the standing wall 4 can be positioned rearward of the bowl surface 2 by that much, and the effective use area of the bowl surface 2 can be expanded.

In the present invention, the washbasin may be configured to be placed on the upper side of the raw tank as in the illustrated embodiment, and a synthetic resin integrated with a cover for covering the front and side portions of the raw tank. And the like.

[Effect] As described above, the low tank hand-washing bowl of the present invention has an extremely large effective use area that can be used for hand-washing. In particular, with the configuration according to claim 2, the effective use area of the bowl surface can be further expanded.
