Description

In the present invention, when the handle of the faucet is rotated and opened, tap water flows out from the outlet of the faucet, and tap water for cleaning the handle spouts from the upper surface of the handle central portion. In addition, the present invention relates to a handle self-cleaning faucet that can self-clean the handle.

  For example, as shown in FIG. 2, the conventional handle turning faucet opens and turns the handle 7 of the faucet and moves the packing 2 upward to provide a water passage hole 18 provided in the partition wall 29 inside the faucet body 1. The tap water is discharged from the outlet 17 of the faucet and used. After use, the handle 7 is closed and rotated, the packing 2 is moved downward, and provided on the partition wall 29 inside the faucet body 1. The water passage 18 is closed to stop the outflow of tap water.

  In the conventional handle turning type faucet, the faucet handle 7 is opened and turned with a dirty hand, the water passage hole 18 inside the faucet is opened, tap water is allowed to flow out from the discharge port, and the hand is washed. After that, the handle 7 is closed and rotated again, the water hole 18 is closed with the packing 2 inside the faucet, and the hand that has been cleaned by performing the operation of stopping the outflow of tap water is attached to the handle 7 before hand washing. It will be dirty again with dirt.

  After washing your hands using the handle-rotating faucet and removing the dirt, scrub the water flowing out from the outlet 17 of the faucet with your hand before operating the faucet handle. Many people stop washing tap water that has been washed and then closed and rotated by holding the faucet handle 7. Some people do the action of scooping water and pouring it over the handle multiple times.

  These actions are performed with anxiety that the dirt attached to the handle 7 will come to the hand again after hand washing, so the water flowing out during that time and the time of people waiting for the order of hand washing is wasted Is.

  In order to eliminate such drawbacks, if the handle 7 of the faucet is opened and rotated, the tap water is allowed to flow out of the faucet outlet 17 and the hand is washed. At the same time, if the handle 7 can be washed with tap water, the faucet will flow out of the outlet 17 after hand washing. The tap water can be rinsed with the hand and hung on the handle 7 to wash away the tap water, and the use time of the hand washing place can be shortened. There is also a faucet devised based on this idea (see Patent Documents 1 and 2 below).

  The problem to be solved is the faucet handle 7 pinched for washing dirty hands, and the handle 7 is operated to operate the handle 7 so as to stop the water after washing. By preventing the hands from getting dirty, the cause of infections in schools, hospitals, etc. can be avoided, and at the same time as the hands are washed, the handle 7 becomes clean and can be used safely.

However, in the prior art faucet devised based on such an idea, the washing water ejected from the upper part of the handle 7 for washing the handle 7 cannot adjust the ejection amount, and the handle washing water even when unnecessary. If the steering wheel 7 cannot be stopped and the opening of the handle 7 is further continued, a large amount of washing water is ejected from the upper portion of the handle 7 and scattered around.

The faucet of the present invention can adjust cleaning tap water ejected from the upper center of the handle 7 regardless of the amount of rotation of the handle 7 and increase the outflow amount from the discharge port 17 of the faucet body. When the opening rotation of the handle 7 is advanced more than a predetermined amount, the washing water spray is adjusted independently of the operation of the handle 7 so that the cleaning tap water sprayed from the upper center of the handle 7 does not scatter around. It is to provide a handle self-cleaning faucet that can be stopped.

According to the first aspect of the present invention, there is provided a faucet body outer wall which is a water faucet which is attached to the end of a water pipe and can be freely discharged and stopped by turning a handle, and the faucet body outer wall is integrally formed. A partition wall that separates the tap water pipe side and the discharge port side, a water passage hole that is provided on the partition wall and that allows tap water pumped from the water pipe side to flow to the discharge port side, and The packing is configured to allow the water hole to be freely opened and closed and to adjust the amount of water flow, and a spindle having one end joined to the central portion of the handle and the other end coupled to the packing. The spindle is disposed on the outflow side of the partition wall. By having a hollow portion provided inside the spindle and a first opening communicating with the space in the faucet body above the spindle screw portion, a water passage is formed between the space inside the faucet and the upper part of the handle, In the handle central portion, there is a handle central portion and a second opening communicating with the hollow portion of the spindle.

Invention of Claim 2 is an invention which stops the flushing water jet of the said faucet when the amount of outflow is increased further from the state which the tap water flowed out from the discharge outlet of the faucet.
In order to increase the amount of outflow from the discharge port of the faucet, when the handle is rotated more than a predetermined amount in the opening direction, the first opening provided above the spindle screw portion is moved upward by the rotation of the spindle. It moves into the triangular packing, the first opening is closed, and the ejection of the handle cleaning water can be stopped.

Invention of Claim 3 is an invention which adjusts the ejection amount from the said faucet upper part.
A cleaning water adjustment knob and a cleaning water stop valve that can freely adjust the distance between the central portion of the handle and the second opening provided at the top of the spindle are provided in the central portion of the handle, and the handle is rotated to a predetermined position. When the tap water continues to flow out from the faucet discharge port and spout as cleaning water from the upper surface of the handle, the amount of cleaning water ejected can be adjusted by rotating the cleaning water adjustment knob. Further, only the ejection of cleaning water can be stopped by turning the cleaning water adjusting knob.

  In the invention according to claim 4, since the packing capable of adjusting the amount of water flow is tapered, the amount of outflow does not change abruptly due to the rotation of the handle, and the amount of water ejected from the upper part is also this. It can be gradually increased or decreased in conjunction with.

The handle self-cleaning faucet of the present invention ejects a large amount of washing water from above the handle when the amount of outflow from the discharge port of the faucet body is increased. At this time, the cleaning water opening / closing knob is turned and closed, and the cleaning water stop valve is moved downward to adjust the second opening with the cleaning water stop ring provided at the top of the handle presser. The amount of water ejection can be adjusted. When the washing water is not required to be ejected, the washing water stop valve is further lowered so that the washing water does not scatter around. It can also be stopped by being brought into close contact with the washing water stop ring.

When connecting a hose to the outlet of the faucet body for the purpose of watering, etc., and increasing the outflow amount, increase the opening rotation of the handle more than the predetermined, but in this case, the first opening passes through the packing receiver The tap water does not flow into the first opening due to the inside of the triangular packing, and the wash water sprayed from the upper part of the handle can be stopped without operating the wash water opening / closing knob.

The handle self-cleaning faucet of the present invention can use the main parts of the conventional handle rotation faucet, the packing receiver, the triangular packing, and the packing presser as they are. Therefore, a handle self-cleaning faucet can be obtained by simply replacing the packing, spindle, handle, handle presser, washing water stop valve, washing water stop valve holder, washing water opening / closing knob, and washing water opening / closing knob fixing bolt.

In addition, the packing 3 having a high consumption frequency is not integrated with the spindle, but can be replaced only by the packing, which is more economical than the conventional replacement of the spindle and packing.

You can touch the handle with peace of mind because the person who washed the dirty hand himself / herself attached to the handle does not get dirty again by pinching the handle for the purpose of turning the handle closed with a clean hand. It is clean without having to wash the handle with scooped water, it is a measure for preventing infectious diseases, and the use time of hand washing can be shortened, resulting in water saving effect.

Unlike the sensor-type faucet, the handle self-cleaning faucet of the present invention can be installed anywhere as long as water pipes are installed, does not require electrical equipment, and is hygienic compared to conventional handle-rotating faucets It can be installed in public facilities, schools, hospitals, parks, etc. without being affected by blackouts in the event of a disaster, etc. and can be used hygienically in any condition as long as there is no obstacle to water supply facilities Can do.
