Description

Electric Boiler {ELECTRIC BOILER}

The present invention relates to an electric boiler, and more particularly to an electric boiler to maximize the heating efficiency of the boiler by exhibiting the maximum thermal efficiency with a minimum of power.

As is well known, a boiler is a device that generates heat energy using fuel and electricity such as oil and gas as energy sources, and generates heating water or hot water by heat exchange of heat energy and water. It is divided into electric boiler.

Combustion type boilers using fuels such as oil and gas as energy sources generate heat energy by burning fuel by a burner, and generate heating water by heat-exchanging water circulating pipes by operating heat energy and a pump. .

However, combustion boilers are expensive because many components are used for storing, supplying, burning, and exhausting fuel, and have a disadvantage in that productivity is greatly reduced due to a complicated structure. In addition, the combustion boiler should be equipped with a separate boiler room that is well ventilated and separated from the heating area in order to prevent the gas poisoning accident caused by the air supply and burnout of the exhaust gas required for burning the burner. The length of the pipe installed between the heating zone and the heating zone is complicated, so that there is a problem that the loss of thermal energy is large, the workability is greatly reduced.

In the case of gas boilers, gas poisoning and explosion accidents caused by gas leakage cause enormous loss of life and property, and thus, it is cumbersome and inconvenient to operate such as requiring periodic inspection of burners and pipes.

On the other hand, electric boilers have the advantage of easy installation and operation compared to combustion boilers because of the use of electricity as an energy source, there is a disadvantage that easily occurs, low energy efficiency.

In order to reduce the operation cost of the electric boiler, it is operated at midnight (22:00 to 08:00 the next day) when the electric charge is discounted, and generates and stores hot water at about 90 ℃, and the user uses the hot water at the required time. There is a variety of late-night regenerative electric boilers.

Representative of the various types of electric boilers as described above is shown in Figure 1, looking at the configuration as follows.

A heating tube (7) with a built-in heating coil (5) and sealed with a vacuum, a sealing tube (8) including the heating tube (7) and a heat transfer medium (6) surrounding it, and a boiler case (1) A water tank (2) provided therein and filled with a plurality of the closed tube (8) and heating water and including an inlet (4) and an outlet (3) for the inflow and outflow of the heating water, and the water The control unit 9 controls the temperature of the heating water by controlling the flow of current applied to the heating coil 5 in response to a temperature sensor installed in the tank, a heating water setting temperature, and a signal of a boiler operation switch.

In the conventional electric boiler having the above structure, when heating the water in the water tank (2), it supplies power to the heating coil (5) to heat the heating tube (7) first, the heated heating tube (7) Silver heats the heat transfer medium (6) secondly, the heated heat transfer medium (6) heats the closed tube (8) thirdly, and the heated closed tube (8) is fourthly watered in the water tank (2). Will be heated.

In the conventional water heating method of this type, starting from the heating coil (5), since the water in the heating tube (7) → heat transfer medium (6) → closed tube (8) → water tank (2) must be heated sequentially As a result, rapid heating is not achieved, and there is a disadvantage in that a lot of heat is consumed and power is consumed. In addition, since the water heating of the water tank 2 heats and expands the area gradually from the part in contact with the surface of the closed tube 8 to the outside thereof, there is a problem of heat loss and rapidity, which is inferior. Energy) is consumed a lot.

In the water heating method of the conventional water tank, heat is generated at the surface of the heated hermetically sealed tube 8 when the hermetically sealed tube 8 is heated at a high temperature. As well as forming a fine gap between the surface and the water in contact with the surface, as well as bubbles and water film is generated on the surface of the sealed tube 8, the heat of the sealed tube 8 is not 100% transferred to the water (actual 70 80%) There is a problem that the power (energy) consumption accordingly increases.

7 is an electric circuit diagram of the electric boiler of the present invention.

Hereinafter, an electric boiler according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the electric boiler of the present invention, as shown in FIG. 2, an upper space is provided by separating separators 11 and 12 separating and separating the upper and lower portions, respectively, on the inner upper and lower portions of a cylindrical tank body 10 having an empty space therein. It is formed by dividing the three into 17 and the central space 19 and the lower space (18).

At this time, the height (length) of the central space 19 is preferably higher than the height of the upper and lower space (17.18). The reason is to increase the heating efficiency of the fluid by maximizing the length of the heating wire 21 installed in the connecting pipe 20 described below. However, the fluid means boiler water.

The central space 19 is provided with a plurality of connection pipes 20 are provided with a heating wire 21 for communicating the lower space 18 and the upper space 17, the installation of the connection pipe 20 The reason is that the fluid supplied from the fluid supply port 16 installed in the lower space 18 is heated by the heating wire 21 installed in the connecting pipe 20 and proceeds to the upper space 17 through the connecting pipe 20. To do that.

Meanwhile, the heating wire 21 installed in the connection pipe 20 is installed outside or inside the connection pipe 20 to heat the fluid flowing through the connection pipe 20, but preferably, the connection pipe 20. It is good to install inside. This is because the fluid flowing through the connecting pipe 20 and the heating wire 21 are in direct contact to maximize the heating efficiency of the fluid.

In the above-described electric boiler of the present invention, the fluid is supplied to the lower space 18 through the fluid supply port 16, and the fluid supplied to the lower space 18 is upper through the lower portion of each connection pipe 20. As it proceeds to be heated by the heating line 21 is discharged to the upper space 17, the discharged heating fluid is discharged through the fluid outlet (15).

In the above manner, the fluid is heated by the heating line 21 and the fluid discharged to the fluid outlet 15 may be used as heated water (hot water), and as shown in FIG. Connected to the front end of the fluid circulation pipe (H) for heating the destination, and connected to the rear end of the fluid circulation pipe (H) after heating the destination to the fluid supply port 16 can be used as a heating boiler. .

Meanwhile, a plurality of lower fluid guide plates 14 are installed in the lower space 18, and a plurality of upper fluid guide plates 13 are installed in the upper space 17, so that the lower space 18 and the upper space 17 are provided. ) Are divided into a plurality of upper / lower fluid induction spaces 17a.18a, and the upper / lower space 17.18 is divided into a plurality of upper / lower fluid induction spaces by using the upper / lower fluid guide plate 13.14. An embodiment of partitioning (17a.18a) is described as follows.

In the method of partitioning the lower space 18 using the lower fluid guide plate 14, the lower fluid guide plate 14 installed at the foremost (fluid supply port 16 side) of the lower space 18 is the foremost ( It is installed to accommodate only one row of the lower connection pipe 20 of the fluid supply port 16 side, and then the remaining lower fluid guide plate 14 is installed to accommodate the lower two rows of the heat pipe 20.

In addition, the method of partitioning the upper space 17 using the upper fluid guide plate 13, the upper fluid guide plate 13 installed in the rearmost (fluid discharge port 15 side) is the rear end (fluid discharge port 15 ) Side) is installed to accommodate only one row of upper connection pipe 20, after that the remaining upper fluid guide plate 13 is installed to accommodate each of the two upper rows of heat pipe 20.

The reason why the upper / lower fluid guide plate 13.14 is installed in the above manner is that the fluid supplied to the fluid supply port 16 flows from the bottom to the top through the front heat pipe 20 as shown in FIG. 2. The fluid is advanced to the top through the adjacent heat pipe 20, and the fluid proceeds to the bottom through the heat pipe 20, the heating proceeds from the bottom to the top again through the heat pipe 20 This is to maximize the heating efficiency of the fluid by the line (21).

As described above, the fluid is continuously discharged from the lower part to the upper part and the upper part to the lower part, and when the fluid reaches the connecting pipe 20 located at the rearmost column, the fluid is discharged through the fluid outlet 15.

The above method of partitioning the upper / lower space (17.18) by using the upper / lower fluid guide plate (13.14) is an embodiment of the present invention and in addition, connecting pipe (20) to one upper / lower space (17.18). ) May be accommodated in one or more rows or two or more rows.

It can also be used by supplying it directly from a line.

In addition, each heating wire 21 provided in each of the connecting pipes 20 is provided with a control unit C for supplying and cutting off power to each of the heating wires 21, and the control unit C is partially heated. 21 cuts off the power supply and supplies power to only some of the remaining heating wires 21 to control the heating of the fluid, thereby selectively turning on the heating wires 21 in consideration of the heating temperature and the external temperature of the heating destination. It is to save electric energy by turning on / off.

The control unit C may supply the power to all of the heating wires 21 to heat the fluid, or may not heat the fluid by cutting off the power supply to all the heating wires 21. The power supply and cutoff control of the heating line 21 as described above is performed by the control unit (C).

When the part of the heating wire 21 cuts off the power supply and supplies only the remaining part of the heating wire 21 to heat the fluid, the heating temperature of the heating destination is selectively adjusted as necessary to control the electric energy. In addition to saving energy, it is possible to save electricity by heating while appropriately controlling the heating temperature of the heating destination according to the season (winter, spring and summer).

In addition, when the fluid is heated by supplying power to all of the heating wires 21, the outdoor temperature is very low, and when the power supply is cut off to all the heating wires 21, the fluid is not heated. It is when it is not running.

The electric boiler of the present invention as described above can be used to control the heating temperature of the heating destination with a single boiler regardless of the heating area of the heating destination, as well as to appropriately adjust the heating temperature of the heating destination according to the outdoor temperature.
