Abstract

PURPOSE: An electric heater boiler is provided to effectively use hot water and to heat water without using a separate accumulator by integrally forming an electric heater with a boiler. CONSTITUTION: An electric heater boiler includes a water reservoir(3) having temperature sensors therein. A heater(4) is installed in the water reservoir(3). A circulation motor(12) is operated based on a signal applied by temperature sensors installed in a water tank(19). An air layer(16) is formed between the water reservoir(3) and an outer cover(6) so as to effectively store hot water for a long time. A valve(11) is installed so as to prevent the water leakage when the circulation motor(12) is separated from the system for the purpose of repairing. Heated water and heat medium oil are returned to the water tank(9) through an overdrain pipe(7).

Description

Midnight Electric Electric Heater Boiler {.}

1) The present invention relates to a midnight electric heater boiler, and more particularly, it is installed next to an existing oil boiler to supply oil developed in the late night electric heater boiler (1-1) to the water boiler of the oil boiler. ) To prevent the use of boiler oil used in oil boilers and to prevent the generation of noise and smoke generated when using oil boilers and harmful gases when using coal briquette boilers. The purpose is to.

2) Generally, energy sources of boilers are usually oil, briquettes, electricity (night power), but when oil is expensive, briquettes emit harmful gases such as briquette gas, which can damage many lives. In addition, the late-night electric boiler has a problem that the device is too large and the price is too expensive.

Accordingly, the present invention is designed to solve the above-described problems as described above 2) as an electric heater and the boiler integrally configured to install the boiler (1-1) beside the existing oil boiler without having a separate heat storage device After that, it can be used by connecting to the oil boiler water tank, and also installed a midnight electric heater (Fig. 2) alone (not connected to the oil boiler) so that the heating water and hot water can be used.

1 is a cross-sectional view and piping diagram of a late-night electric heater boiler connected to an oil boiler showing an embodiment according to the present invention.

Figure 2 is a cross-sectional view and piping at the time of installation alone midnight electric heater showing an embodiment according to the present invention

1 is a cross-sectional view and a piping diagram of a late-night electric heater boiler connected to an oil boiler in accordance with an exemplary embodiment according to the present invention, and FIG. The idea was to connect the midnight electric heater to the oil boiler basin (Figure 1). It was also intended to be used as a nighttime electric heater boiler alone (FIG. 2).

That is, the present invention is a boiler using a conventional oil boiler and the water pipe (8) of the boiler (1-1) by using a temperature sensor (S1) built in the blister (3) of the boiler (1-1) The heating heater 4 installed in the boiler blister 3 is operated according to the signal of S2, and the circulation motor 12 is operated in response to the signal of the temperature sensor S3, S4 in the circulation water reservoir 19. By operating the heated water to the existing oil boiler blister through the water pipe (8), economical and efficient heating water and hot water can be used, and the boiler blister (3) and outer cover ( 6) By forming a state of (air layer and vacuum) 16, it is possible to maintain warm heating water for a long time in the hot water state, and also heated water when separating from the pipe during repair and replacement of the circulation motor 12 Leaked out of the tube In order to prevent the valve 11 was installed, water and thermal oil in the boiler (1-1), (Fig. 2) is supplied to the water supply tank (9) automatically through the pipe 18 without a flow meter The heated water and the heat medium oil were freshened to the water tank 9 again through the overdrain pipe 7, and the boiler (FIG. 2) was individually heated using an individual heating distributor 20. It is configured to use hot water by installing a hot water pipe 21 in the blister (3) of the boiler (Fig. 2).

Therefore, in the present invention, by installing a night electric heater heater using a hot water heated by electric heater and hot water (when the electric heater heater is installed alone) by the oil boiler by connecting to the boiler 1-1. By using it, the oil cost reduction effect and the use of the boiler (Fig. 2) alone do not use oil, which has a significant effect on the prevention of oil use and the prevention of gas poisoning accidents caused by the use of briquette boilers. ) Is significantly smaller than other company's late-night electric boilers and uses low-power heaters 1kw, 1.5kw, 2.3kw, and the electricity usage fee and equipment cost is very low, and the boiler (1-1) (Fig. 2) does not add electricity It is designed to be used without it and is very useful because it is easy to move and install.
