Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mixer faucet for hot and cold water used mainly for domestic use, and in particular to water heaters such as solar water heaters, gas water heaters, boilers, and electric water heaters. The present invention relates to a hot water mixing faucet in which hot water supply and water supply thereto are performed by a single hot water mixing faucet.

(Prior Art) Traditionally, hot water obtained from water heaters such as colonic water heaters, boiler water heaters, electric water heaters, gas water heaters, etc. has been used as it is or by mixing it with water. There is. By the way, when water is supplied to the water heater or hot water obtained by the water heater is supplied somewhere, the actual situation is that dedicated piping is installed separately from other equipment.

For this reason, for example, if we consider a solar water heater as a water heater, when using hot water from this solar water heater in a home bathroom, there is no problem if there is enough hot water at a predetermined temperature or higher in the solar water heater. However, if this hot water runs out, there will be the following inconveniences.

,■ Conventional water supply to solar water heaters often supplies only the amount of water that is used up each time. Therefore, since water is supplied as soon as the water in the solar water heater starts to be used, the hot water, which has reached a predetermined temperature, mixes with the water and its temperature drops. For this reason, especially in the winter, even though the temperature of the hot water is not that high, it further decreases due to the mixing of water, so the temperature drops immediately after starting to use the hot water. In this way, if the temperature of the hot water in the solar water heater drops to, for example, about 35°C, it cannot be used as bath water.

・Water must be supplied to the solar water heater for the next solar heating, but only the person in the bathroom who has used up the hot water is aware of the need for this supply, and that person is not required to perform the operations to supply water. must be done outside the bathroom or be attended to by someone else.

(Since multi-solar water heaters are installed outdoors, water must be drained to prevent freezing in the winter. This draining operation is done by opening and closing the drain valve each time. However, this is a very tedious task.

The above is a case where a solar water heater is considered as a water heater, but when considering other water heaters in general, conventional hot water mixer faucets have the following problems.

■Once installed on a wall or the like, piping for supplying hot water and water cannot be easily changed. Also, the salary i
The specifications of s differ depending on each manufacturer. Therefore,
The more you consider the future, the more difficult it becomes to decide what type of mixer faucet to use.

・8) Furthermore, since the hot and cold water mixing faucet is operated not only by adults but also by children, it is necessary that the hot water and cold water mixing faucet be easy to operate.

A hot water mixer faucet eliminates the inconveniences mentioned above.

It can be said that there was still not enough.

(Problems to be solved by the invention) The great invention was made in view of the above-mentioned circumstances, and the problems to be solved include not only the mixing of hot and cold water, but also water heaters, boilers, and electric hot water. To provide a hot water mixer faucet which can easily perform hot water supply control of other equipment such as a water heater and water draining operation of the water heater as needed.

Switching handle (30) for selecting water supply path
As shown in Fig. 1, the sensor rod (30a) is connected horizontally, and the control valve body (33) is connected to the λ end of the sensor rod (3(l&) shown in Fig. 9). The control valve body (33) is arranged in the second water supply chamber (32), and the first water supply chamber (31) is located on the left side of the second water supply chamber (32) in FIG. The chamber (31) communicates with the water pipe (300) through the water supply pipe (11), thereby supplying water from the water pipe (300) into the first water supply chamber (31). Also, this first water supply room (31).

It communicates with the hot water mixing chamber (R) through a second passage (17b) formed in the mixing faucet body (10) and a second connection hole (23b) of the fixed valve body (23). Furthermore, a communication hole (31a) is formed in the wall located between the first water supply chamber (31) and the second water supply chamber (32).

On the other hand, the second ice compartment (32) is connected to the water supply pipe (210) of the solar water heater (200) through the second connection pipe (13). a (200). Further, as shown in FIG. 2, the second water supply chamber (32) in this example has a right ventricle (32a) and a left ventricle (3) separated by a wall (35).
2b). And the second water supply room (32
) is provided with a drain valve (34) in the right ventricle (32a), and by opening this drain valve (34), the water in the solar water heater (200) is drained to prevent it from freezing in winter. This is so that it can be done.

In this example, as shown in FIG.

A backflow prevention valve (40) is inserted between the hot water mixing faucet (100) and the water pipe (300). This check valve (
40) mainly consists of a rod (41), a piece (42), a backing (41a) (41h), and a spring (43). a hole (
44) by blocking the hot water mixer tap (10G)
This is to cut off communication between the water pipe (300) and the water pipe (300). Further, the spring (43) urges the rod (41) and the piece (42) toward the hole (44), and
The hole (44) can be opened only when the pressure on the side (300) is high. Therefore, this check valve (
40) prevents hot water or water from flowing back into the water pipe (300) from the mixer faucet (100).

(Action of the invention) The hot water mixer faucet (+00
) has the following effects. In other words, if you want to use the hot water in the solar water heater (200) first,
By rotating the switching handle (30), the control valve body (33) is brought into contact with the communication hole (31a).
The communication between the water supply room (31) and the second water supply room (32) is cut off, so that hot water from the solar water heater (200) and water from the water pipe (300) enter the hot water mixing room (R). It is only the state in which .

If you move the mixing lever (20) upward in this condition,
Mixed hot water at the set temperature at the mixing position of the mixing lever (20) can be drawn out from the faucet (14) or shower opening (15). Of course, by mixing and setting the position of < -(20) to a desired temperature position in advance, mixed hot water at a desired temperature can be obtained. If this mixed hot water is no longer needed, the mixing lever (20) can be lowered. Raise the mixing lever (20) again.

You can get mixed hot water at the temperature you set earlier.

At this time, the control valve body (33) closes the communication hole (31a) by operating the switch/handle (30).
Water from the water pipe (30G) does not enter the second water supply chamber (32), so cold water does not flow into the solar water heater (200).

Also, I/) that supplied water to the solar water heater (200)
In this case, by operating the switching handle (30), the control valve body (33) is opened from the communication hole (3La) and brought into contact with the wall (35). As a result, the first water supply room (31) and the second water supply room (32) are communicated with each other, so water from the water pipe (3QO) is transferred to the first water supply room (31),
It is supplied into the solar water heater (20G) through the second water supply chamber (32) and the second connection pipe (13). At this time, water from the water pipe (300) is also supplied into the hot water mixing chamber (R) through the first water supply chamber (31);
If you lower (20) and set it to the water supply position, it will not flow out from the faucet (10 C±shower (15)).
.

Furthermore, in the case of draining the water in the solar water heater (20G) in the winter season with this hot/cold water mixing faucet (10G), it is recommended to do the following. In other words, the drain valve (30) provided on the right ventricle (32a) side is always kept open.Then, the switch/drain valve (30) is fully rotated to the right or left. One.

Then, the control valve body (33) either contacts the wall (35) or closes the communication hole (31a). If the control valve body (33) closes the communication hole (31a), the water pipe (3
QO) water does not enter the second water supply chamber (32),
If the control valve body (33) is in contact with the wall (35), the right ventricle (
32a) and the left ventricle (32b) is cut off, water from the water pipe (300) enters the left ventricle (32b) but not the right ventricle (32a). Supplying water into the vessel (200) and draining water therein can be performed independently.

Furthermore, when using another water heater such as a boiler in place of the solar water heater (200), the hot water mixing tap (10
0) can also be used in the following ways: 0 For example, when using a boiler as a water heater, C±.

Although hot water must be used and water must be supplied at the same time,
In such a case, the control valve body (33) is moved away from both the communication hole (31a) and the wall (35) of the second water supply chamber (32) shown in FIG. 2 by operating the switching handle (30). As a result, the entire first water supply chamber (31) and second water supply chamber (32) will be in communication with each other.
The water in the water pipe (300) flows from the first water supply chamber (31) into the hot water mixing chamber (R), and from the second water supply chamber (32) to the water supply pipe (
210), it is possible to simultaneously supply water into the water heater.

(Effect of the invention) - The hot water mixer faucet (100 mm) according to the present invention configured as described above
), it is possible to mix water and hot water at a predetermined temperature, shut off the water, and supply water to the solar water heater (200) in one place. Therefore, the person in the bathroom who recognizes the necessity of supplying water to the solar water heater for the next solar heating can be done immediately without leaving the bathroom. Moreover, at this time, by using the switching handle (30), water can be supplied to the solar water heater (200) after the hot water in the solar water heater (20G) is completely exhausted. As a result, the hot water in the solar water heater (200) can be completely used up without mixing water with it.

Also, if you use a mixer faucet like this (10G).

Since piping between the solar water heater (200) and the water pipes (300) can be done in one place, or at least in a nearby place, for example, in the conventional system, the solar water heater (200)
0), two hot water supply control valves, one control valve for the water pipe (300), and a 1 m valve for adjusting the set temperature of the mixed hot water, which required a total of five valves, is the hot water of the present invention. Mixing faucet (10
0), the mixing valve body (22) and the control valve body (33)
can be reduced to two. Therefore, the hot water mixing faucet (100) has the advantage that the piping that has already been installed can be used as is, and the installation cost is not required.

Furthermore, the hot water/cold water mixer faucet (100) mixes /<-
(20), can be used by operating the switching nozzle (30) and the switching knob (18), so it is relatively easy for anyone to understand and prevents mistakes in the hot water mixer faucet (100). Activation can be prevented.

In addition, the second water supply chamber (32) is connected to the right ventricle (
32a) and the left ventricle (32b),
Supplying water to the solar water heater (200) and draining water therein can be performed independently, and the right ventricle (32
Since the drain valve (34) provided on the a) side can be kept open at all times, draining operation in winter can be performed extremely easily.

Furthermore, the hot water mixing faucet (100) is configured such that the control valve body (33) is separated from both the communication hole (3ta) and the wall (35) of the second water supply chamber (32) by operating the switching handle (30). In this case, the first water supply chamber (31) and the second water supply chamber (32) can be in communication with each other, and the water pipe (
300) from the water supply chamber (31) to the hot water mixing chamber (R
) and from the second water supply chamber (32) to the water supply pipe (210)
Since it is possible to simultaneously supply water into the water heater through the water heater, it can also be used in other water heaters.
