Abstract

A small sized electric boiler is provided to remove air, to circulate hot water, and to increase heating efficiency by placing filter nets at a moving path and a discharge port and preventing the air from being discharged to the discharge port. A small sized electric boiler comprises a heater(3), a hot water recovery hole, a heating part, a moving path, a discharge port, and a water container(10). The water container supplies water to the water tank and discharges air of the water tank. A second filter net(7) is placed at the moving path to expand small air bubbles so that the small air bubbles are not flown to the pipe through the discharge port. A filter net(7') is placed at the discharge port to prevent the air from the discharged to the discharge port.

The present invention relates to a small electric boiler, and more particularly, to a small electric boiler that is easy to process air, as well as no noise.

In general, an electric boiler supplies electric energy to a heater that is an electric resistor, heats water with heat generated while electricity is supplied, and then heats or heats the heat source by heat exchange while allowing the heated water to circulate the heat source. It is well known that hot water can be used directly.

Therefore, in the related art, a coil in which a resistor is built in a copper pipe or stainless pipe while filling an insulating magnesia is used to be bent in a desired shape, and the heater is mounted in a heating chamber for heating the heating water and directly heated. It is common to use mainly.

 However, bubbles are generated in the heating water during heating of the heater. In other words, when air is generated in the pipe and the low casting, and the generated air is not discharged to the outside, the hot water does not circulate in the pipe due to the air layer, which hinders heating. Therefore, conventionally, after installing an air valve that can discharge air in the pipe, the user periodically discharges the air by using the air valve.

In addition, the circulation of the heating water is circulated using a forced circulation pump that generates noise.If the air layer that is out of the circulation of the heating water is solved, that is, no air layer is generated, a small boiler does not require a circulation pump depending on the installation location. .

Reference here, as shown in FIG. 3, a small boiler (omitted forced circulation pump) was applied to the sofa to repeat the research and experiment. As a result, when the air bubbles are blocked from entering the piping that is the heating hose, the heating water does not interfere with the circulation. I learned this absence.

Here, the conventional coal-fired boiler is to circulate the hot water boiled in the boiler with only its own vapor pressure as a hot water circulation method by the level difference without using a forced circulation pump. Therefore, when bubbles enter the heating pipe, the bubbles impede the hot water circulation.

 An object of the present invention is to provide a small electric boiler is installed in the pipe and the filter net to block the air in the hot water pipe of the boiler so that the generated air is not introduced into the pipe while the air (bubble) generated in the water tank of the boiler to the outside. The purpose is to provide.

In order to achieve the purpose, it is configured as follows.

A heater 3 capable of heating water in the reservoir 9, a recovery hole 4 in which hot water is recovered, and water recovered from the recovery hole 4 are heated by the heater 3 A part 5, a moving path 6 through which hot water heated from the heating part 5 moves, a discharge port 8 through which hot water is discharged to the pipe 100 in the case of the moving path 6, and In the electric boiler including a water tank 10 through which the water of the water tank 9 is discharged at the same time as water is supplied to the water tank 9, the air generated from the pipe or the water tank 9 is discharged to the discharge port 8. In order to prevent flow through the discharge port 8 to the pipe 100, a filter net 7 ′ is installed to prevent air from passing through the discharge port portion.

First, it will be described with reference to FIGS.

A heater 3 capable of heating water in the reservoir 9, a recovery hole 4 in which hot water is recovered,

A heating part 5 in which water recovered from the recovery hole 4 is heated by the heater 3,

 A moving path 6 through which hot water heated from the heating part 5 moves;

A discharge port 8 through which the hot water is discharged to the pipe 100 via the moving path 6, and a bucket 10 through which the air of the reservoir 9 flows out at the same time as the water is supplied to the reservoir 9. In an electric boiler,

A strainer (7 ') to prevent air from being discharged to the discharge port so that air generated in the pipe or the reservoir 9 in the discharge port 8 does not flow into the pipe 100 through the discharge port (8). Characterized in that installed.

In the case of small air bubbles, since the rising speed is slow and flows into the pipe through the discharge port 8 through which hot water flows, a second sieve network 7 is formed in the moving path 6 to form a small air bubble.

In this way, the present application installed the second filter net (7) in the moving path (6) as a result of the naked eye (reservoir tank made of transparent material) as a result of the small air bubbles pass through the second filter net (7) the second filter net (7 It was confirmed that the larger the cross-section. Therefore, it was confirmed that the large air bubbles rise quickly and are discharged to the outside via the water tank 10 located above the water tank 9.

Reference numeral 101, which has not been described, is a control box for controlling temperature by controlling storage in the heater, and 102 is a control unit for controlling the control box.

Control box as shown in Figures 1 and 3 can be separated from the electric boiler as needed.

Example

1 is an exploded perspective view of the present application connecting a known pipe, Figure 2 is a perspective view of the side wall cut, Figure 3 is a state diagram applying the electric boiler of the present application to the sofa 200.

As shown in the first and third embodiments shown in the drawing, the pipe is piped to, for example, a sofa, and then connected to the recovery hole 4 and the discharge port 8, respectively. At this time, it is desirable to remove the residual air remaining in the pipe before the connection.

Then, after filling the reservoir and the water with water and applying current to the heater 3 via the control box 101, the heater heats the water filled in the heating part 5 and the heated water is synergistic. Pass through the second strainer (7,7 '). Of course, it also passes through the air chamber contained in the hot water, and the air bubbles become larger. Therefore, the large air bubbles rise rapidly and are discharged to the outside via the water tank located above the reservoir 9.

In this process, some small air bubbles move toward the discharge port, but there is a sieve blocking the entrance of the discharge port 8 so that the small air bubbles rise and are directed to the water tank.

Therefore, the air does not flow into the pipe does not interfere with the hot water circulation.

And the supplemental water of the reservoir (9) is supplied from the bucket (10).

In addition, the small electric boiler of the present application as shown in FIG. 3 can be conveniently used by being located at a predetermined position on the sofa when the control box 101 is separated.

In addition, as shown in FIG. 5, not only can a heating pipe be buried in the floor of a space that requires heating, but also can be used wherever there is a power source such as an electric blanket or an electric blanket.

The second filter net 7 is further described as a dust collecting device for collecting small air bubbles in one place. Therefore, small bubbles gathered in one place are combined to become large bubbles. This could be confirmed through experiments.

In addition, FIG. 6 is integrated with the first manure network and the second manure network and installed as shown in FIG. 6.

As described above, air is not introduced into the pipe by discharging the air, which hinders the circulation of hot water, from the reservoir to the outside. In other words, there is an advantage to increase the heating efficiency because the hot water is circulated by removing the air.

 In addition, a separate forced circulation pump and an air valve for discharging air have been omitted. Therefore, the manufacturing cost is reduced as well as the realistic small boiler is provided. Therefore, it can be called a very advantageous invention.
