It relates to a low-temperature electric boiler equipped with a hot water supply device using the internal heat of the boiler.

In general, a boiler is a device that generates heat energy using fuel or electricity such as oil or gas as an energy source, and generates heating water or hot water by heating a medium, that is, water, using the generated heat energy. It is divided into boiler, gas boiler and electric boiler.

Here, since boilers using fuels such as oil and gas as energy sources burn a fuel, many components are used for storing, supplying, burning, and exhausting fuel, and are expensive, and the structure is complicated, which greatly reduces productivity. In order to prevent the gas poisoning caused by the leakage of the exhaust gas and the supply of air required for the combustion of fuel, a separate boiler room must be provided which is well ventilated and separated from the heating zone. There is a problem that the length of the pipe is complicated and long, so that the loss of thermal energy is large and the workability is deteriorated. In the case of gas boilers, gas poisoning and explosion accidents caused by gas leakage cause enormous loss of human life and property, and thus it is cumbersome and inconvenient to operate, requiring periodic inspection of burners and pipes.

On the other hand, since electric boilers use electricity as an energy source, installation and operation are easier and hygienic than combustion-type boilers, and the risk of accidents due to overheating is relatively small, and the number of users is increasing.

The electric boiler is configured to directly or indirectly heat a large-capacity storage tank for storing water supplied from a water supply source and an electric heater that generates and circulates water stored and circulated inside the storage tank, and in the storage tank. It is used to supply the heated water to the building's heating water or hot water for living by heating piping and heating pump.

That is, the electric boiler heats the low temperature water stored in the reservoir 2 through the water supply pipe 5 to the high temperature through the heat transfer heater 3 installed in the lower portion of the reservoir 2 as shown in FIG. To be discharged. At this time, the low temperature water stored in the water storage tank 2 is gradually heated by the heat transfer heater 3, and is heated as a whole while circulating the inside of the water storage tank 2 by the temperature difference. That is, the water stored in the reservoir 2 is heated as a whole over time.

Here, the water supply pipe 5 and the drain pipe 4 are connected to the circulation heating pipe not shown. Therefore, the heating pipe not shown heats the floor using hot water supplied to the drain pipe 4, or supplies warmth to the plastic house of the factory or farmhouse through a blower fan not shown.

In the non-illustrated heating pipe, both ends are connected to the drain pipe 4 and the water supply pipe 5, respectively, to form a closed loop. Therefore, the heating pipe receives and circulates high temperature hot water through the drain pipe 4, and then supplies the hot water cooled while being circulated to the water supply pipe 5 again.

That is, the heating pipe is re-supply the hot water used for heating to the water supply pipe (5) so that the hot water of the hot water converted into low temperature water while being used for heating is heated again by the electrothermal heater (3) and recycled through the drain pipe (4). do.

At this time, the hot water re-supplied to the water supply pipe 5 by the heating pipe is converted to low temperature by heat exchange during heating and resupplied. That is, the water supply pipe 5 is supplied with low temperature low temperature water. Therefore, the heat transfer heater 3 heats again the low-temperature water supplied to the water supply pipe 5 and supplies it to the drain pipe 4 of the water storage tank 2.

However, such a general electric boiler is a hot water is discharged through the drain pipe (4) only when the low-temperature water stored in the reservoir (2) is heated by the heat transfer heater (3), as shown in the Not only can not be used, there is a problem that the heating time of the low temperature water is very excessive.

In particular, when the boiler is manufactured in a large capacity, the low temperature water of the large water tank 2 is heated for about 1 hour so that the low temperature water is heated to a temperature suitable for heating. Therefore, a large-capacity general electric boiler not only can not immediately use hot water, but also can not be used continuously in a timely manner, and only a heating time of about 1 hour can be used to perform substantial heating.

In addition, a general electric boiler manufactured in a large capacity has an upper drain pipe of the water storage tank 2 while the electric heater 3 heats low temperature water that is re-supplied to the lower water supply pipe 5 of the water storage tank 2 after heating. Since hot water of the reservoir 2 is discharged to (4), there is a problem that the electrothermal heater 3 should be continuously operated without stopping.

On the other hand, even if the low temperature water of the reservoir (2) is heated by the heat transfer heater (3) to become hot water, when the external temperature of the reservoir (2) is low, the hot water of the reservoir (2) generates heat loss and heats the heat energy according to the heat loss. Since the heater 3 needs to be replenished, the heating efficiency is lowered.

The present invention has been made to solve the above problems, the object of the present invention is to provide a separate dual heating section (1 chamber, 2 chamber) in the inside of the storage room by using the heating medium after heating the rapid initial It is to provide a low-temperature electric boiler equipped with a hot water supply device using the internal heat of the boiler that can shorten the time from operation to heating.
