Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric boiler using a heating oil consisting of multiple coils,
The present invention relates to an electric boiler comprising a plurality of coils. More particularly, the present invention relates to an electric boiler for heating a heat medium oil to increase the temperature thereof, The present invention relates to an electric boiler using a heating medium oil, which is made up of multiple coils, which are heated after being uniformly heated on the whole surface, and then heated and fed through a heat exchanger.
Generally, a boiler is a device that generates heat energy by using fuel or electricity such as oil or gas as an energy source, and generates heating water or hot water by heating the medium, that is, water, with generated heat energy. Boilers, gas boilers, and electric boilers.
Here, since the boiler using the fuel such as petroleum or gas as the energy source burns the fuel, many parts such as fuel storage, supply, combustion, and exhaust are used, which is expensive and the structure is complicated, , It is necessary to provide a separate boiler room, which is ventilated and isolated from the heating area, in order to prevent the gas poisoning accident due to the supply of the air required for the combustion of the fuel and the leakage of the exhaust gas, There is a problem that the length is complicated and elongated, the loss of thermal energy is large, and the workability is deteriorated. In the case of a gas boiler, a gas poisoning and explosion accident caused by a gas leak causes an enormous loss of human life and property, so that it is troublesome and inconvenient to operate such as periodical inspection of a burner and piping.
Electric boilers use electricity as an energy source, so they are easier to install and operate than hygienic boilers, hygienic, and the risk of accidents due to overheating is relatively low, and the number of users is increasing.
The electric boiler has a large-capacity storage tank for storing water supplied from a water supply source, and indirectly heating the water to be stored and purified in the storage tank by an electric heater which is heated by electricity. In the storage tank, The heated water is used as heating water for buildings or hot water for living by heating pipes and heating pumps.
In other words, the electric boiler supplies low-temperature water stored in the water storage tank through the water supply pipe to the lower portion of the water storage tank
It is heated to a high temperature through an installed electric heater and discharged to a drain pipe. At this time, the low temperature water stored in the water storage tank is gradually heated by the electrothermal heater, and the whole is heated while circulating the inside of the water storage tank by the temperature difference. That is, the water stored in the water tank is heated as time passes.
Here, the water supply pipe and the water pipe are connected to the circulating heating pipe. Accordingly, the heating pipe supplies the warmth to the greenhouse of the factory or the farmhouse through the blowing fan or the floor by using the hot water supplied to the drain pipe.
These heating pipes are connected to the drain pipe and the water pipe at both ends, respectively, to form a closed loop.
Accordingly, the hot piping is supplied with hot water of high temperature through a drain pipe, circulates the hot water, and then supplies hot water, which is circulated and circulated, back to the water pipe.
That is, hot water used for heating is re-supplied to the water pipe so that hot water, which has been changed to low temperature water while being used for heating, is again heated by the electric heater and recirculated through the water pipe.
At this time, the hot water re-supplied to the water supply pipe by the heating pipe is converted into a low temperature by heat exchange at the time of heating and is re-supplied. That is, low-temperature low-temperature water is supplied again to the water supply pipe. Therefore, the electrothermal heater reheats the low-temperature water supplied to the water supply pipe and supplies it to the pipe of the water storage tank.
However, in such a general electric boiler, since the low-temperature water stored in the water tank is heated by the electric heater, the hot water is discharged through the water pipe, so that the hot water can not be used immediately in time and the heating time of the low- There is a problem.
In particular, when a general boiler is manufactured in a large capacity, the low temperature water of a large water tank is heated for about one hour so that the low temperature water is heated to a temperature suitable for heating. Therefore, a large-capacity general electric boiler can not use hot water immediately and can not be used in a timely manner. Only about one hour of heating time is required to perform practical heating.
Also, since a general electric boiler manufactured with a large capacity discharges hot water discharged from the water tank to the upper side drain pipe of the water tank while heating the low temperature water supplied to the lower side water pipe after heating after the heating, the electric heater can be continuously There is also a problem that needs to be activated.
On the other hand, even if the low temperature water of the water tank is heated by the electric heater, if the external temperature of the water tank is low, the hot water of the water tank generates heat loss and the heat energy due to the heat loss must be supplemented by the electric heater, .
