Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot and cold water mixing faucet device for discharging hot and cold water mixed from a neck-shaped currant.

Conventional technology Conventionally, this kind of hot and cold water mixing faucet device used to turn a knob in opening and closing operation, but since the hot and cold water mixing faucet device is used by the whole family from elderly people to children,
It needs to be simple and easy to use, but the action of turning the knob is difficult for the elderly and children with weak grip strength, and when soap is on the hands, it becomes difficult to use and the problem is solved. It was rare.

Therefore, recently, a single lever hot and cold water mixing and faucet device as shown in FIG. This is such that when the single lever 3 is opened and closed to open and close the discharge of the mixed water from the hot and cold water mixture discharge port 2 at the tip of the neck-shaped curran 1, it is opened when the single lever 3 is lowered. Reference numeral 4 is a tub for receiving the mixed water from the hot / water mixed water discharge port 2.

Further, a self-closing type hot and cold water mixing and faucet device as shown in FIG. 5 like the second conventional example has also been developed. 5 is a knob for adjusting the temperature, 6 is a knob for switching the discharge of the mixed water between the neck-shaped curran 1 side and the hose 7 side connected to the shower, 8 is the push button that is lowered when pushed and the push button is returned to its original position when released. It is a lever, and when the push lever 8 is pushed, the hot water mixed water discharge port 2 automatically shuts off when mixed water equivalent to one vat has come out.

There is also a third conventional example. As disclosed in Japanese Utility Model Laid-Open No. 59-86476, a contact switch is provided on the faucet in the faucet that opens and closes water with a short neck shape that is usually installed in a bathroom or toilet to wash hands. However, there has been a method in which the prime mover makes one revolution by operating the switch once, and the opening / closing plug connected to the prime mover is opened for a certain period of time to supply a certain amount of water.

Problems to be Solved by the Invention However, although the single lever and the self-closing type shown in the conventional example have become very easy to use, when actually used every day, there are still problems to be solved. Was there. The first problem is that in a bathroom where a hot and cold water mixing faucet device is often used, either the mixed water discharged from the hot water mixed water discharge port 2 is used directly, or the operation of receiving the mixed water into the trough 4 is extremely large. The person naturally fixes his / her body so that his / her hands can easily use the mixed water directly or can easily receive the mixed water in the trough 4. However, the position B at which the single lever 8 is operated is located farther back than A because the calan 1 has a neck-long shape, so the body must be tilted forward each time it is operated, and this movement is weak. It was distressing for the elderly and difficult to use because of the large forward leaning movement for small children. The second problem is that it is necessary to operate with the eyes closed when washing the head, and the user can squeeze his hand invisible, or the single lever method of the conventional example, and the self-closing type of hot and cold water. In both configurations of the mixed faucet system, there are a plurality of protrusions on the front side, which are the cullan and the lever, and it is difficult to understand and use. In addition, water and hot water are supplied to the hot and cold water mixing faucet device, but if the condition of covering the hand with the blindness as described above continues for a long time, the hand touches the pipe of the hot water and burns. There was a safety issue of doing so. In addition to the above-mentioned problems, there are problems that the number of projections does not give a neat appearance to the design, and the number of projections increases damage to a fall accident.

In addition, in the bathroom, it is necessary to wash the head, use a shower, wash towels, wash tools, etc. in the bathroom, and in the kitchen, open and close frequently, such as washing dishes, tools, washing hands, and washing clothes of different sizes. Since the amount of mixed water to be used varies, the structure in which one tub is automatically filled with one operation is inconvenient and creates a new problem of wasted mixed water and waiting time.

The present invention, in order to solve the above problems, each time to operate,
(EN) A hot and cold water mixing device which does not cause pain to an elderly person with a weak waist without leaning forward and which is easy to use for a child with a small body and does not have a large forward leaning motion. It is an object of the present invention to provide a safe hot and cold water mixing device that does not cause burns by touching the hot water piping.

Means for Solving the Problems In order to solve the above problems, the hot and cold water mixing faucet device of the present invention is a hot and cold water mixing means for mixing hot water and water, a neck-shaped currant for discharging the mixed water, and A single switch provided at substantially the tip of the neck-shaped curran, an opening / closing means for electrically opening and closing the discharge of the mixed water from the currant, and a switch for discharging the mixed water each time a signal from the switch is input. It has a control means for controlling the opening / closing means so as to alternately start and stop.

The present invention has the above-described configuration, and since the single switch is located in the vicinity of the neck-shaped shaped water discharge portion of the currant, the neck-shaped shape of the neck-shaped portion near the water outlet of the mixed water is maintained even during invisible hair washing. You can easily find the location of the switch by operating the single switch provided on the tip of the Karan, so your hands will not touch the hot water pipes and will not get burned, and your waist will be weak. No need to put a strain on your lower back because you can wash it without leaning forward, even for the elderly and small children.
