Description

  The present invention relates to a hand-washing / water-discharging device that is provided with a hand-washing / water-discharging pipe at the upper part of a toilet's washing tank in a toilet and that supplies water from a ball tap to the hand-washing / water-discharging pipe and discharges water from a water outlet at the tip to a hand-washing bowl. It is related with what has the feature in the technical means for shortening.

The toilet tank flush tank has a drain valve at the bottom and a ball tap inside. The drain valve is opened when the toilet is washed, and the wash water stored inside is discharged toward the toilet. At the same time, water supply is started from the water supply port in the tank of the ball tap, and cleaning water is supplied to the inside of the tank.
In general, a wash basin is provided at the top of the wash tank, and a hand wash water pipe is provided there, and part of the water is introduced to the hand wash water pipe when water is supplied from the ball tap to the hand wash bowl. Water is discharged.

In the hand-washing / water-discharging device including the hand-washing / water-discharging pipe, when the water discharge from the hand-washing / water-discharging pipe is stopped, that is, when the water discharge is stopped, unlike the normal water discharge from the water faucet of the faucet, the internal space of the hand-washing / water discharge pipe is usually removed. The buried water escapes into the washing tank through the water supply port of the ball tap tank, and the internal space of the hand washing water discharge pipe becomes empty.
Therefore, when handwash water is to be discharged from the hand-washing water pipe again by water supply from the ball tap, the interior space of the hand-washing water pipe once empty must be filled with water from the ball tap.

In the case of water discharge from the normal water faucet pipe, when the water is stopped, the water inside the water discharge pipe does not flow out but stays in the water discharge pipe. Water is discharged from the water discharge pipe immediately.
However, in the case of the hand-washing water discharge pipe provided in the hand-washing basin of the washing tank, water cannot be discharged from the water outlet unless the interior space is first filled with water.
That is, water discharge is not performed until a certain time has elapsed since the start of water supply to the hand-washing water discharge pipe, and a certain time lag occurs during that time.

  By the way, in recent years, design has been strongly demanded for hand washing and discharging water pipes in hand washing and discharging devices, and the shape of the hand washing and discharging water pipe (the shape of the main body portion appearing outside) has been changed to a quadrangular shape and the like. There is a tendency that the hand wash water discharge pipe becomes larger by making it into a square shape, and in this case, the volume of the internal space of the hand wash water discharge pipe becomes larger than before, and it takes time to fill it with water. End up.

In other words, the time required for water discharge from the hand-washing water discharge pipe is longer than before, which causes irritation and discomfort to the user.
On the other hand, if the water discharge pipe is made thin in order to avoid this, this greatly restricts the degree of freedom of design of the water discharge pipe.

In addition, there exists what was disclosed by the following patent document 1 as a prior art relevant to this invention.
This is provided with a water-impervious member that changes the flow of water at a position immediately upstream of the water discharge port, and once the water flow is blocked by the water-impervious member and pushed upward, the water flow is discharged from the water discharge port wide. It was made like that.
However, what is disclosed in this Patent Document 1 is related to a water faucet for a normal water faucet, and in addition, the water ejection from the water spout is delayed by providing a water shielding member. Are different.

On the other hand, it can be firmly fixed in a state where it does not move relatively.

  Further, although the embedding member 46 is formed of a resin molded product having relatively easily dimensional variations, the dimensional variations can be absorbed by the compression of the ribs 64 and the convex curved portions 66 described above. Even if there is a variation in dimensions of the embedded member 46, the embedded member 46 can be satisfactorily fixed in the fitted state inside the hand-washing water discharge pipe 26.

  Further, in the present embodiment, since a part of the internal space of the hand washing water discharge pipe 26 is filled with the embedding member 46 in the main body 34 that forms the large size of the hand washing water discharging pipe 26, The internal space can be effectively largely filled, and thus the time until the hand washing water is discharged from the water outlet 28 can be shortened effectively.

In the present embodiment, the upward internal space of the hand-washing water discharge pipe 26 is filled so that the gradient of the ascending flow path 50 becomes the steepest, and when water discharge from the hand-washing water discharge pipe 26 is stopped, that is, when the water is stopped, The water in the inside can be drained downward.
In particular, when the hand-washing water discharge pipe 26 is not used for a long period of time, it is possible to eliminate the occurrence of a portion where water remains in the interior, and to prevent problems such as bacterial growth there. .

  In the present embodiment, a thin blow molded product of resin is used as the embedding member 46. By using such a flexible member as the embedding member 46, the molding accuracy is not so high. The embedded member 46 can be easily fitted into the hand washing water discharge pipe 26.
