Description

Detailed Description of the Invention The present invention combines a solar water heater and a hot water boiler for the purpose of resource saving, supplies all water to the hot water boiler from the solar water heater, and also supplies water from water pipes to the solar water heater. This relates to a hot water mixing faucet that can freely mix and use hot water from a hot water boiler and hot water from a hot water boiler.

Conventionally, such solar water heaters and hot water boilers were installed separately, and each was designed to supply hot water and boiling water independently, making it impossible to effectively utilize the heat from both. However, since multiple switching valves are required in the piping to switch between the two, the switching operation becomes complicated and there is a risk of erroneous operation.Also, if the hot water boiler is used alone, the water supply to the hot water boiler is Since the water is directly connected to the pipe, it was necessary to install a pressure reducing valve in that passage to prevent excessive water pressure from being applied to the hot water boiler.

In view of these drawbacks, the present invention combines a solar water heater and a hot water boiler so that all water to the hot water boiler is supplied from the solar water heater, and water from the water pipes and hot water from the solar water heater are combined. , a hot water mixing faucet with three valves to freely mix and adjust the heat from the hot water boiler is connected to water pipes, a solar water heater, and a hot water boiler, and can be used to discharge only water or hot water just by operating in the bathroom. Discharge of hot water only, discharge of only hot water, discharge of mixed water of water and hot water, discharge of mixed water of water and hot water, discharge of mixed water of hot water and boiling water, discharge of mixed water of water, hot water and boiling water An example of the implementation of the present invention will be explained below based on the drawings. 1 is a solar water heater mounted and fixed on the roof, 2 is a solar water heater installed outdoors. The closed hot water boiler, 3, is a hot water mixer tap installed in an indoor bathroom.

To explain each connection circuit here, the water pipe 4 is branched into two directions, one side is connected to the water inlet 5 of the hot and cold water mixing faucet 3, and the other is connected to the water inlet 6 of the solar water heater 1.
Furthermore, the flow path from the discharge lower of hot water heated by the solar water heater 1 is branched into two directions in the middle, one side is connected to the receiving spout 8 of the hot water mixing faucet 3, and the other side is connected to the water inlet 9 of the hot water boiler 2. Furthermore, a discharge port 10 for hot water heated by the hot water boiler 2 and a heat receiving port 11 for the hot water mixing faucet 3 are connected to the hot water boiler 2.
are connected.

As mentioned above, all of the water supplied to the hot water boiler 2 is supplied from the solar water heater 1, and since the hot water heated by the solar water heater 1 is used, the water is heated by the hot water boiler 2. In this case, the amount of heat can be greatly saved, and since the water supply in this case uses the head difference between the solar water heater 1 and the hot water boiler 2, the water pressure of the water supply is always constant, and the depressurization that is normally essential for the hot water boiler 2 can be avoided. There is no need for any valves or the like.

Next, to explain the structure of the hot water mixing faucet 3, 12 is the main body of the hot water mixing faucet 3, and the main body 12 includes a water chamber 13 that communicates with the water receiving port 5 from the water pipe 4, and a water chamber 13 that communicates with the water receiving port 5 from the water pipe 4. A hot water chamber 14 communicating with the hot water receiving sprue 8 and a hot water chamber 15 communicating with the hot water receiving sprue 11 from the hot water boiler 2 are formed respectively, and the water chamber 13, the hot water chamber 14, and the hot water chamber 15 are formed in the upper part of each chamber. A common mixing chamber 16 is formed which communicates with chamber 15.

Also, water from water pipe 4 and hot water from solar water heater 1,
As a mechanism for allowing the hot water from the hot water boiler 2 to flow into the mixing chamber 16 individually, a water heater having a valve 18 that can open and close the water passage 17 between the water chamber 13 and the mixing chamber 16 from the upper part of the main body 12 by rotational operation. A handle 19, a hot water handle 22 having a valve 21 that can open and close a hot water flow path 20 between the hot water chamber 14 and the mixing chamber 16 by rotation, and a hot water chamber 15.
A handle 25 for hot water having a valve 24 that can be opened and closed by rotating operation between the hot water passage 23 between the hot water flow path 23 and the mixing chamber 16 is attached to each, and the discharge amount of water, hot water, and hot water to the mixing chamber 16 can be adjusted separately. I am making it happen as much as I can.

The mixing chamber 16 also has a discharge port 26 for discharging mixed water, which is a mixture of water, hot water, and boiling water, to the outside.
A discharge pipe 27 for supplying mixed water to a bathtub or the like is inserted into the discharge port 26.

In addition, the water pressure of the water pipe 4 is approximately 2 to 6 -/-1 The water pressure of hot water from the solar water heater 1 is approximately 0.6 to 0.71 w/ff1 (5 m
When installed at a height of ~7 m), the water pressure of the hot water from the hot water boiler 2 is also approximately 0.6~0.7 kg/cyiY, and the water pressure is approximately 0.6~0.7 kg/cyiY, and the water pressure is adjusted to make it easier to adjust the mixing of water, hot water, and boiling water. A constant pressure valve 28 made of rubber is inserted into the water port 5 to adjust the water pressure of water flowing from the water pipe 4 to approximately 0.6 to 0.7 kg.
A constant pressure of /crlt is maintained, and the pressure balance between hot water and boiling water is reached in the mixing chamber 16.

It has been adjusted before. Since the hot water mixing faucet 3 is configured as described above, the water handle 19 and the hot water handle 22 are
By rotating the hot water handle 25, any one of water from the water pipe 4, hot water from the solar water heater 1, and hot water from the hot water boiler 2 can be used alone or under the following seasonal conditions. A mixture of can be used.

For example, in summer, the temperature raising ability of the solar water heater 1 is limited, so a mixture of hot water from the solar water heater 1 and water from the water pipe 4 is used.

If the solar water heater 1 alone does not provide enough heat during winter, etc., use the hot water from the hot water boiler 2 and the water pipe 4.
Mixing hot water from solar water heater 1 and hot water from hot water boiler 2 is more energy efficient than mixing it with water from hot water boiler 2, so a mixture of hot water and boiling water is used. .

In this case, all the water supplied to the hot water boiler 2 uses hot water heated by the solar water heater 1, so the amount of heat used to heat the hot water boiler 2 can be saved, resulting in a further energy saving effect.

In addition, when the solar water heater 1 is of little use during winter, or when all the hot water from the solar water heater 1 has been used, the hot water from the hot water boiler 2 and the water from the water pipe 4 are combined. Use mixed water.

These mixing adjustments are just examples, and water, warm water, and boiling water can be mixed freely according to the usage conditions of the user.

In short, the hot water mixer faucet according to the present invention includes a water chamber 13 communicating with the water pipe 4, a hot water chamber 14 communicating with the solar water heater 1, a hot water chamber 15 communicating with the hot water boiler 2, the water chamber 13, the hot water chamber 14, and the hot water chamber 15 communicating with the hot water boiler 2. A common mixing chamber 16 communicating with the chamber 15 and the discharge port 10 is formed in the main body 12, and the mixing chamber 16 and the water chamber 13, the hot water chamber 14, and the hot water chamber 15 are connected from the outside of the main body 12 by rotating operation. Valve that opens and closes 18°21.
24, a water handle 19, a hot water handle 22,
Since the hot water handles 25 are respectively attached, by rotating the three handles, only water can be discharged from the water pipe 4, only hot water can be discharged from the solar water heater 1, only hot water can be discharged from the hot water boiler 2, and only hot water can be discharged from the hot water boiler 2. The discharge of a mixture of water and hot water, the discharge of a mixture of water and hot water, the discharge of a mixture of hot water and boiling water, and the discharge of a mixture of water, hot water, and boiling water can all be operated in the bathroom. In addition, since a constant pressure valve 28 is installed at the water inlet 5, the water pressure from the water pipe 4 is kept constant, and the pressure balance between hot water and boiling water is adjusted to maintain a stable mixture of hot water and water. Its practical effects are enormous, such as being able to provide the following.
