Hot water distributor for boilers with heating system

The present invention relates to a hot water distributor for a boiler having a heating device, and more particularly, because cold water at the initial stage of operation of the boiler is quickly heated and supplied by the hot wire of a hot water heater installed in the hot water distributor, the user can use the hot water heated to a set temperature in the boiler. Hot water of the desired temperature can be used faster than the time it takes to be supplied. When the temperature of the hot water in the boiler or hot water heating unit gradually rises to the set temperature, the opening and closing ports of the valve opening and closing parts are opened more and more, and a large amount of hot water is supplied through the valve opening and closing part, so that the water that was not initially heated is thrown away. It relates to a hot water distributor for a boiler having a heating device that can save water by minimizing it.

In general, a hot water distributor is used to distribute and supply hot water heated in a boiler to a bathroom, kitchen, or laundry faucet for hot water use.

In particular, if you turn on the water or shower after setting the boiler to the hot water function to use hot water, cold water will come out for a while at first.

The user waits for a certain amount of time while running the water until the hot water of the desired temperature comes out. Finally, when the hot water heated to the set temperature comes out, the hot water is used.

Conventionally, as described above, there was a problem of causing unnecessary waste of water when using hot water.

In addition, a certain period of time elapses for the boiler to ignite and heat the water to the set temperature, and the user has no choice but to wait until the water is heated depending on the boiler.

In other words, water is wasted due to water that has to be heated by using a boiler and simply flowed out until hot water is used. There was discomfort.

Therefore, there is an urgent need to develop a device for supplying hot water that is quickly heated to a usable temperature while saving water.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In the accompanying drawings, the same components are used with the same reference numerals in any possible drawings, and detailed descriptions of known functions or known components that may unnecessarily obscure the subject matter of the present invention are omitted.

1 to 3, the hot water distributor for a boiler having a heating device according to an embodiment of the present invention includes a distributor body 1, a hot water heating unit 100, a hot water distribution unit 300, and a valve. The opening and closing unit 200 is included.

The distributor body 1 receives hot water from the hot water supply pipe 140 connected to the boiler and supplies hot water to each hot water discharge pipe 310 to supply hot water to a place where hot water is needed.

The hot water heating unit 100 is installed at the rear end of the distributor body 1 to heat the hot water introduced from the hot water supply pipe 140 with a heating wire 120 heated by electrical connection.

The hot water heating unit 100 is configured to include a control unit 110 , a heating wire 120 , an incoming water temperature measuring sensor 130 , and a pressure measuring sensor 160 .

The control unit 110 is installed at the rear end of the distributor body (1). A temperature display window 111 may be installed in the control unit 110 to check the temperature of the heating wire 120 , and a set temperature of the heating wire 120 may be adjusted by installing a control unit 112 .

The rear end of the heating wire 120 is connected to the control unit 110 and the front end of the heating wire 120 protrudes toward the inside of the distributor body 1 to heat the hot water introduced into the distributor body 1 . The heating wire 120 is electrically connected and heated, and the control unit 110 controls on/off and temperature control of the heating wire 120 .

The incoming water temperature measuring sensor 130 is installed in the connection part where the hot water supply pipe 140 and the distributor body 1 are connected, measures the incoming water temperature, and sends the measured value to the control unit 110 to operate the heating wire 120 . turns on/off. In addition, as shown in FIG. 1 , the incoming water temperature sensor 130 may be installed at the front end of the control unit 110 into the coupling pipe 150 of the distributor body 1 .

Thus, the hot water heating unit 100 is supplied to the distributor body 1 by the heating wire 120 of the hot water heating unit 100 installed in the distributor body 1 until the water heated to the set temperature in the boiler comes out. It heats up the cold water of the machine and heats it up quickly to supply hot water with the set temperature desired by the user more quickly. And, when the hot water supplied from the boiler is heated to the set temperature, the incoming water temperature sensor 130 installed on the hot water supply pipe 140 side of the distributor body 1 detects and sends a signal to the control unit 110, the control unit 110 to stop the operation of the heating wire 120 .

The hot water distribution unit 300 is installed at the front end of the distributor body 1 to receive hot water from the hot water heating unit 100 and supply it to each hot water discharge pipe 310 .

Since the hot water distribution unit 300 supplies the hot water that has passed through the valve opening and closing unit 200 of the distributor body 1 to each hot water discharge pipe 310, when the temperature of the hot water is lower than the set temperature, the hot water is supplied by the valve opening and closing unit 200. A small amount is supplied, and when the temperature of the hot water is gradually increased as much as the set temperature, the hot water is gradually supplied by the valve opening and closing unit 200, so that water can be saved.

The pressure measuring sensor 160 is installed in the connection part where the hot water supply pipe 140 and the distributor body 1 are connected, measures the pressure when the boiler is not used, and sends the measured value to the control unit 110 to turn off the power. makes it In addition, as shown in FIG. 1 , the pressure measuring sensor 160 may be installed at the front end of the control unit 110 into the coupling pipe 150 of the distributor body 1 .

That is, when the boiler's hot water supply is not used, the internal water pressure of the distributor body 1 increases, so the pressure value measured by the pressure measuring sensor 160 is sent to the control unit 110 and the control unit 110 cuts off the power. When the boiler is not in use, the temperature of the water inside the boiler and the distributor body 1 drops, and even if the incoming water temperature sensor 130 detects this, the heating wire does not work, so that standby power is not generated.

The valve opening and closing unit 200 is installed between the hot water heating unit 100 and the hot water distribution unit 300, and when the temperature of the hot water supplied from the hot water heating unit 100 is lower than the set temperature, the shape memory alloy spring 240 is It is microscopically stretched and finely opened the opening 221 to allow a small amount of hot water to pass through, and when the temperature of the hot water gradually rises to the set temperature, the shape memory alloy spring 240 expands and contracts more and more to open the opening 221 more and more. It provides a water-saving effect by allowing more and more hot water to pass through. In addition, when the temperature of the hot water supplied from the hot water heating unit 100 is below the temperature at which the shape memory alloy spring 240 expands and contracts, the shape memory alloy does not expand and contract, so the opening and closing opening 221 is slightly opened.

To this end, the valve opening and closing unit 200 is configured to include a stepped (211,212), a protruding jaw (220), a disk valve (230), a shape memory alloy spring (240), a bias spring (250).

Steps 211 and 212 are respectively formed along the inner periphery of the distributor body 1 so as to have a predetermined interval back and forth between the hot water distribution unit 300 at the front end of the distributor body 1 and the hot water heating unit 100 at the rear end of the main exhaust body. .

The protrusion 220 is formed along the inner periphery of the distributor body 1 in the middle of the both side steps 211 and 212 .

The disc valve 230 is disposed on the rear side of the protruding protrusion 220 to open and close the opening 221 formed by the protruding protrusion 220 , and both ends of the disc valve 230 are in contact with or Since they are spaced apart, the opening and closing ports 221 are opened and closed.

The shape memory alloy spring 240 is interposed between the front step 211 and the protruding jaw 220 so that the front end of the shape memory alloy spring 240 is in contact with the front step 211 and the rear end of the shape memory alloy spring 240 . is in contact with the front surface of the disk valve 230 . The shape memory alloy spring 240 does not expand and contract when the temperature at which the shape memory alloy spring 240 reacts or less, and when the temperature at which the shape memory alloy spring 240 reacts is higher than the temperature at which the shape memory alloy spring 240 responds, it gradually expands and contracts to open and close the opening 221. By pushing the valve 230, it is possible to open and close the opening 221.

The bias spring 250 is interposed between the protrusion 220 and the rear step 212, the front end of the bias spring 250 is in contact with the rear surface of the disc valve 230, and the rear end of the bias spring 250 is the rear step ( 212) is contacted.

The operation and effect of the present invention configured as described above will be described in detail as follows.

First, when describing the operation of the hot water heating unit 100,

When the user turns on the boiler and turns on the faucet to use hot water, the hot water with the desired temperature is not supplied at first because the boiler is in the early stage of operation, but cold water is supplied. Thus, the hot water heating unit 100 is supplied to the distributor body 1 by the heating wire 120 of the hot water heating unit 100 installed in the distributor body 1 until the water heated to the set temperature in the boiler comes out. It heats up the cold water of the machine and heats it up quickly to supply hot water with the set temperature desired by the user more quickly. And, when the hot water supplied from the boiler is heated to the set temperature, the incoming water temperature sensor 130 installed on the hot water supply pipe 140 side of the distributor body 1 detects and sends a signal to the control unit 110, the control unit 110 to stop the operation of the heating wire 120 . Then, the user will be supplied with hot water heated to the set temperature in the boiler from now on.

Next, when describing the operation of the valve opening and closing unit 200,

At the beginning of the boiler operation, when the temperature of the hot water passing through the hot water heating unit 100 of the distributor body 1 is lower than the set temperature, the shape memory alloy spring 240 expands and contracts only by a minute length, and the disk which blocked the opening 221 By lightly pushing the valve 230, the tension of the bias spring 250 is overcome, and the opening/closing opening 221 is slightly opened. At this time, a small amount of hot water is supplied.

And, as the temperature of the hot water gradually rises to the set temperature, the shape memory alloy spring 240 is also gradually expanded and contracted to gradually push the disc valve 230 that opens and closes the opening and closing port 221 more and more strongly, pushing the opposite side of the disc valve 230. By overcoming the tension of the bias spring 250, the shape memory alloy spring 240 pushes the disk valve 230 toward the bias spring 250 further, so that the opening/closing opening 221 is opened more and more. Then, the hot water is supplied without clogging, so that the user can smoothly use the hot water heated to the set temperature.

That is, when the temperature of the hot water at the initial stage of the heating wire operation is lower than the set temperature, a relatively small amount of hot water passes through the valve opening and closing unit 200 and is supplied to the hot water distribution unit 300, and when the temperature of the hot water gradually rises by the set temperature, the valve opening and closing unit Since the amount of hot water supplied to the hot water distribution unit 300 through 200 is gradually increased and is smoothly supplied, water can be saved as a result.

This is because, due to the nature of the user, when the water is cold, the water is simply poured and used only after the water temperature is warmed to the desired temperature.

And, finally, when the temperature of the hot water supplied from the boiler reaches the set temperature, the operation of the heating wire 120 is stopped by the incoming water temperature sensor 130 of the hot water heating unit 100, and the opening/closing opening 221 of the valve opening and closing unit 200 ) is also sufficiently open, so that the user can use the hot water heated and supplied by the boiler.

Therefore, in the present invention, cold water at the initial stage of operation of the boiler is quickly heated and supplied by the hot wire 120 of the hot water heating unit 100 installed in the hot water distributor, so that the user is more than the time it takes for the hot water heated to the set temperature in the boiler to be supplied. It has the effect of quickly using hot water at the desired temperature.

In addition, in the present invention, when the temperature of the hot water is lower than the set temperature at the beginning of the boiler operation by the operation of the shape memory alloy spring 240 of the valve opening and closing part 200, the opening and closing opening 221 of the valve opening and closing part 200 is finely opened. A quantity of hot water is supplied through the valve opening and closing unit 200, and when the temperature of the hot water gradually rises to the set temperature, the opening and closing ports 221 of the valve opening and closing unit 200 are opened more and more, so that a large amount of hot water is supplied to the valve opening and closing unit 200 ), so that hot water can be used smoothly gradually, thereby saving water.

On the other hand, in the present invention, the valve opening/closing unit 200 and the hot water heating unit 100 are sequentially coupled to and separated from one end of the distributor body 1 of the hot water distributor so that the hot water distributor already installed in the boiler can be utilized.

In other words, according to the present invention, the hot water distribution unit 300, the valve opening/closing unit 200, and the hot water heating unit 100 may be integrally manufactured, and the hot water distribution unit 300, the valve opening/closing unit 200, and the valve opening and closing unit 200 and the hot water heating unit 100 may be manufactured to be coupled and detachable. This is to utilize the distribution pipe of the hot water distribution unit pre-installed in the boiler.

The above-described valve opening/closing unit 200 and the hot water heating unit 100, which are separately manufactured in the hot water distribution unit installed in the boiler, are configured so that they can be combined and separated in sequence. It has a savings effect.

That is, the opening/closing pipe 260 of the valve opening/closing unit 200 is coupled to the distribution pipe 320 of the hot water distribution unit 300 , and the coupling pipe of the hot water heating unit 100 is coupled to the opening/closing pipe 260 of the valve opening/closing unit 200 . (150) is combined. In detail, the male threaded part 262 of the front end of the opening/closing pipe 260 is screwed to the female threaded part 321 of the rear end of the distribution pipe 320, and the coupling pipe is connected to the female threaded part 261 of the rear end of the opening/closing pipe 260. (150) It is possible to screw the male threaded portion 151 of the front end.

At this time, as shown in the accompanying drawings 4, using the connector 400 formed in the form of a bellows, one end of the connector 400 is connected to one end of the distribution pipe 320, and the The other end may be connected to the front end of the opening/closing pipe 260 . If the connection pipe 400 is used, there is an advantage that the opening/closing pipe 260 and the coupling pipe 150 can be more easily combined and separated from the distribution pipe installed in the boiler.

In addition, the step, the protruding jaw 220, the disk valve 230, the shape memory alloy spring 240, and the bias spring 250 are installed inside the opening and closing pipe 260 of the valve opening and closing unit 200.

In addition, inside the coupling pipe 150 of the hot water heating unit 100, the control unit 110, the heating wire 120, and the incoming water temperature measuring sensor 130 are installed.

Therefore, according to the present invention, by configuring the opening/closing pipe 260 of the valve opening/closing unit 200 and the coupling pipe 150 of the hot water heating unit 100 to be sequentially coupled and separated to the distribution pipe installed in the boiler, the minutes installed in the boiler Since the pipe can be used, installation is easy and the cost is reduced.
