Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hot water mixer tap mainly used for domestic use, and in particular to hot water supply from solar water heaters and water supply thereto, boilers, gas water heaters, This invention relates to a hot water mixer faucet that can selectively supply hot water from a forced heating type water heater such as an electric water heater.

(Prior Art) Conventionally, hot water obtained by a solar water heater has been used as it is or in combination with hot water heated by a boiler or the like. by the way.

In reality, when water is supplied to the solar water heater or the hot water obtained thereby is supplied somewhere, dedicated piping is installed separately from other equipment. For this reason, for example, if we consider the case where hot water from this solar water heater is used in a home bathroom, there is no problem if there is enough intestine at a predetermined temperature or higher in the solar water heater, but if this hot water runs out In this case, there are the following inconveniences.

・P In the conventional way of supplying water to solar water heaters, water was often supplied to replace the amount that was used up each time. Therefore, since water is supplied at the same time that the water in the water heater starts to be used, the hot water that has been heated to a predetermined temperature mixes with the water and its temperature decreases. For this reason, especially in the winter, the water causes a drop in temperature even though the temperature is not that high, so the temperature drops as soon as you start using this hot water, for example to about 35 degrees Celsius. Otherwise, it will no longer be possible to use it as hot water.

h) Water must be supplied into the solar water heater for the next solar heating, but only the person inside the bathroom is aware of the need for this supply, and the operation for supplying water must be done outside the bathroom. I have to ask someone else to do it.

・■The hot water supply to the bathroom is switched to be supplied from the boiler, but this operation must be performed after the faucet on the solar water heater side is closed. Therefore,
There are too many taps for the boiler and solar water heater, or they are located far apart.

Its operation is inconvenient.

・'4) For this reason, the piping from the boiler side and the piping from the solar water heater mentioned above must be installed in the same bathroom or in close proximity.

It can be said that there has not yet been a sufficient mixer faucet for hot water and cold water that eliminates the above inconvenience.

Rotate the first changeover handle (2o) and turn the second hot water supply chamber (
22) and the hot water supply passageway (24), while the second switching handle (3o) is rotated to communicate only the first water supply chamber (31) and the hot water mixing chamber (R). If the mixing lever (io) is moved upward in this state, mixed hot water at the set temperature at the mixing position of the mixing lever (10) can be drawn out from the faucet (115) or the shower opening (118). Of course, if the mixing lever (10) is previously set at a desired temperature position, mixed hot water at the desired temperature can be obtained. When this mixed hot water is no longer needed, the mixing lever (10) can be lowered, and by raising the mixing lever (10) again, the mixed hot water at the temperature set earlier can be obtained. At this time, since the second control valve body (33) closes the communication hole (31a) by operating the second switching handle (30), the water in the water pipe (400) flows into the second water supply chamber (32). Therefore, no cold water flows into the solar water heater (2f)O).

When the hot water in the solar water heater (200) runs out, rotate the first switching handle (20) to change the passage communicating with the hot water supply passage (24) from the first hot water supply chamber (21) to the second hot water supply chamber (22).
). As a result, hot water from the forced heating type water heater (300) is supplied into the hot water supply passageway (24), so that this hot water is mixed with water in the hot water mixing chamber (R). At this time, if the temperature of the hot water from the forced water heater (300) is high, the temperature of the 7% mixed water that is derived can be reset by rotating the mixing lever (10) by a predetermined amount.

When switching from the first hot water supply chamber (21) to the second hot water supply chamber (22) using this first changeover handle (20), by rotating the second changeover handle (30), the first water supply chamber (31) and the second water supply chamber (32) are switched to communicate with each other. By this, water pipe (400
) from the hot water mixing chamber (R
), as well as the second water supply chamber (32
), solar water heater (200) through the water supply pipe (210)
Since hot water is also supplied to the inside of the solar water heater (200), the hot water in the forced heating type water heater (300) is used and the water shortage in the solar water heater (200) is also supplied at the same time.

(Effect of the invention) The hot water mixing faucet (100
), mixing water and hot water at a predetermined temperature, switching the required hot water supply destination from a solar water heater (200) to a forced heating type water heater (300), and a solar water heater (200).
This alone can supply water to the area. Therefore, the work of supplying water into the solar water heater for the next solar heating can be carried out without the person in the bathroom who recognizes the need to do so leaving the bathroom.
This can be done immediately by operating only 0). Moreover, at this time, the chopstick two switching handle (
30) by using a solar water heater (200
) After the hot water in ) is completely gone, this solar water heater (2
00), the hot water in the solar water heater (200) can be completely used up without mixing water with it. From the water heater (200) to the forced heating type water heater (
300), a person in the bathroom who needs to do so can do so immediately at that location by operating the hot water mixer faucet (100).

Furthermore, this hot water mixer faucet (100) allows piping for the solar water heater (200) and the forced water heater (300) to be installed at least 11 liters, or at least in close proximity to each other. If you are using a hot water mixing faucet, 2 hot water control valves for the solar water heater (200), 2 control valves for the forced heating type water heater (300), and 1 valve for adjusting the set temperature of the mixed hot water. A total of 5 (2 valves were required, but if the hot water mixer faucet (100) of the present invention is used, the mixing valve body (12), the first and second valve bodies (23),
(33) can be reduced to 3 (!l).Therefore, the hot/cold water mixing faucet (1 (10)) has the advantage of being easy to install and is inexpensive.
