Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water faucet which opens and closes a valve body by operating a lever.

[0002]

2. Description of the Related Art Most of the faucets to date have been of the type in which a handle with a handle is rotated to open a valve body with a coma built in the main body by water pressure.
Since it is very important to keep water saving in order to use water resources effectively, these days, the grip handle is replaced with a lever and the valve body can be opened and closed by one-touch operation. Stoppers are becoming popular.

[0003]

However, in the present situation, even if the grip handle is replaced with the lever in this way, the water saving as expected is not achieved. That is, in the above water-saving type faucet, although the valve body can be opened and closed quickly due to the one-touch operation, the water is used from the time the lever is opened until the water is actually used. Until the valve is closed by operating the lever, the water is wasted, and the amount of wasted water is slightly smaller than that of the grip handle. I'm just there.

Even if the lever operation is one-touch operation, the lever operation is still required whether the valve is opened or closed, and the operation is easier than the grip handle. It was just what I said.

On the other hand, especially when using a faucet installed in a public place or the like, it is impossible for the unspecified number of people to use it, so that the majority of people are
First of all, I received the water in my hand and poured it on the faucet,
In particular, the first thing to do is to wash the handles and levers that you hold, and then wash your hands for the first time.The amount of water used to wash this faucet and the amount of waste water that is released during the wash The amount of water is so huge that it cannot be ignored if it is piled up, which is a serious problem for effective use of water resources.

The present invention has been made in view of the above circumstances, and an object of the present invention is to eliminate the above-mentioned waste of water, to achieve remarkable water saving, and to operate it. It is to provide a faucet that has achieved improvement in sex.

An object of the invention of claim 2 is to not only waste water to achieve remarkable water saving but also to improve operability, and in addition, to automatically discharge the lever at the same time as the water discharge. It is to provide a faucet that can be washed.

An object of the invention of claim 3 is to provide a faucet which can be further improved in usability.

[0009]

In order to achieve the above object, the invention according to claim 1 incorporates a valve body which is closed by the water supply pressure into the main body, and also to the main body side which resists the water supply pressure. The swing lever for opening the valve body when the valve is pushed is provided on the main body so that the valve opening operation portion is located below the water discharge port.

Further, according to the second aspect of the invention, the valve body which is closed by the water supply pressure is built in the main body, and the valve body is opened when the valve body is pushed against the water supply pressure. It is characterized in that the lever is provided in the main body by setting the valve opening operation portion thereof to a position which is relatively opposed to the downward water discharge port of the water discharge pipe when the valve is opened.

Further, in the invention according to claim 1 or 2, the swing lever is held at the pushed position in its final pushing posture, and the final pushing operation is performed by pulling the swing lever. It is characterized in that a swing lever fixing means for releasing the holding of the pushing posture in the posture is provided.

[0012]

According to the water faucet of the present invention having the above-described structure, when the hand is washed, by inserting the hand under the water spout, the swing lever is pushed in and the body side is resisted against the water pressure by the hand or the back of the hand. Then, by automatically pushing in and opening the valve body, water is discharged from above toward the pushed hand. That is, when the hand is washed, the valve body is opened by the action itself of bringing the hand under the spout, and in that state, the hand can be washed immediately without wasting any water.

When the hand washing is finished, the valve body is automatically closed by using the water supply pressure only by pulling the hand from the bottom of the spout, which also wastes water. , The valve body is opened and closed by the swing lever by the action of bringing the hand under the water spout and the action of pulling the hand from the water spout, so that operability is improved at the same time as saving water. .

In particular, when the valve is open, the rocking lever is inevitably washed at the same time as hand washing without wasting water.

If the swing lever is further pushed in to fix the final pushing posture of the swing lever, water can be continuously used as before.
