Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric boiler,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric boiler using a Pettis device, and more particularly, to an electric boiler using a Pettis device, in which hot water is generated by fitting a plurality of pettish devices between a tube and a tube, The present invention relates to an electric boiler using a Pettis device.

Generally, a boiler 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 oil 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, In order to prevent the gas poisoning accidents due to the supply of the air required for the combustion of the fuel and the leakage of the exhaust gas, it is necessary to provide a separate boiler room which is ventilated and isolated from the heating area. The length of the piping is complicated and prolonged, so that the loss of heat 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. In addition, boilers using fossil fuels can be conveniently used as operation buttons only in the room. However, since oil and gas are used, the economical burden is increased when the oil price continues to rise. In addition, when the boiler using only the fossil fuel is used as described above, the combustion gas is continuously discharged, thereby increasing environmental pollution.

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 is adapted to directly and indirectly heat a large-capacity storage tank for storing water supplied from a water supply source and an electric heater for heating and circulating water stored in the storage tank, The heating water is supplied to the heating water of the building or the hot water for living by the heating pipe and the heating pump.

However, since the electric bill is a progressive agent, there is a problem in that the use of the electric boiler causes a burden on the electric bill.

In addition, in most boilers, air is generated in the circulation pipe, which interferes with the circulation of the heating water, thereby lowering the heating efficiency.

In the Korean Registration Practice [20-0385858], a combined electric boiler system of a late night electric boiler and an ordinary electric boiler is disclosed.

Korean Registration Practice [20-0385858] (Registered on May 26, 2005)

1, an electric boiler using a Pettis device according to an embodiment of the present invention includes a heating unit 100, a fluid tank 200, a circulation pump 300, and a control unit 400.

2 to 3, the heating unit 100 includes a first pipe 110, a second pipe 120 spaced apart from the first pipe 120 by a predetermined distance, A plurality of flat tubes 130 having both ends fixed to the first pipe 110 and the second pipe 120 and having flow paths through which fluids can flow and disposed between the adjacent two flat tubes 130, And a plurality of Pittsi devices 140 that generate heat to a predetermined temperature by a power source.

The first pipe 110, the second pipe 120, and the flat tube 130 are formed with a channel through which fluid (water, etc.) can flow.

The fluid is moved along the channel formed in the first pipe 110, the second pipe 120 and the flat tube 130. At this time, the fluid, which is moved to the flat tube 130, Can be heated. The use of the flat tube 130 as a tube is advantageous in that when the fittice element 140 is sandwiched between adjoining flat tubes 130 (see FIG. 2), in order to widen the contact area with the fittie element 140 Which effectively heats the fluid in the tube as heat generated from the Pittsy '

The Positive Temperature Coefficient (PTC) is also referred to as a positive characteristic thermistor. It is a semiconductor device that rapidly increases in electrical resistance when a temperature is raised by a barium titanate (ceramics) It is a heating element. Also, if an electric current flows for a very short time, the electric resistance becomes large and the electric current does not flow. That is, if the resistance changes according to the temperature, it is a safe heating element instead of a nichrome wire because it acts as a switch.

When the power source is applied, the PTC device 140 generates heat in about 200 to 250 degrees after about 30 seconds, and maintains a constant temperature.

The spacing between the flat tubes 130 for inserting the Pitissi element 140 is preferably in consideration of the thickness of the Pitissi element and is generally about 3.5 mm.

The flat tube 130 is preferably formed of an aluminum material having a good thermal conductivity, and is preferably brazed to maintain a gap of 2 to 5 mm.

The fluid tank 200 has an opening 210 formed at an upper portion thereof and an opening and closing portion 220 for opening and closing the opening 210. The fluid tank 200 has a space for storing a fluid therein, An inlet 230 connected to the second pipe 120 or the second pipe 120 is formed at a predetermined distance from the opening 210 and an outlet 240 through which the fluid is discharged is formed at a lower portion.

That is, the heated fluid passing through the heating unit 100 flows into the inlet 230, and the fluid is stored in the fluid tank 200. The fluid stored in the fluid tank 200 is discharged to the circulation pipe through the discharge port 240. Here, the circulation pipe refers to a pipe installed on the floor or wall so that heated fluid (hot water, etc.) flows for heating.

That is, the fluid circulates through the circulation path through the heating unit 100 - the fluid tank 200 - the circulation pipe.

The fluid tank 200 is formed with an opening 210 at an upper portion thereof and an opening and closing portion 220 through which the opening 210 can be opened and closed. The first pipe 110 or the second pipe 120 The inlet 230 through which the fluid is introduced is spaced from the opening 210 by a certain distance so that the liquid in the fluid flowing into the inlet 230 drops downward due to gravity, When the pressure of the inside of the fluid tank 200 is increased due to the gas, the opening and closing part 220 may be opened to discharge the gas to the outside. 1, the opening and closing part 200 is illustrated in the form of a lid. However, any structure is applicable as long as it can discharge the gas inside the fluid tank 200 to the outside. In addition, when the opening / closing part 200 is formed in the form of a lid, a small groove may be formed or a drain cock may be provided to allow the gas to escape. Therefore, it is possible to automatically remove the air without separately performing the operation of removing the air to manage the general boiler.

The circulation pump 300 is connected to the piping on the side of the discharge port 240 to circulate the fluid.

In other words, the circulation pump 300 pushes the fluid stored in the fluid tank 200 to the circulation pipe so that the fluid can be circulated through the circulation path through the heating unit 100, the fluid tank 200, and the circulation pipe It plays a role.

The control unit 400 is connected to the Pittsi device 140 and the circulation pump 300 and controls the Pittsi device 140 and the circulation pump 300.

The controller 400 is driven by the power supply and must be driven according to the temperature setting, the time setting, the season setting, the hot water exclusive setting, , The time setting, the season setting, the hot water only, and the like, and controls the Pittsi device (140) and the circulation pump (300).

4, the heating unit 100 of the electric boiler using the Pittsy's element according to an embodiment of the present invention divides a predetermined portion of the first pipe 110 and the second pipe 120 into sections Wherein the partitioning part 150 includes a predetermined number of the flat tubes 130 so as to be staggered with respect to the first pipe 110 and the second pipe 120, To allow the fluid to pass through in a "shape "

The reason for allowing the fluid to pass through the heating unit 100 in the shape of "d" is to make the flow length of the fluid long enough to sufficiently heat the fluid from the fluidity element 140. For example, about four to ten tubes can be made up as a unit to allow water to pass in an "e" shape.

4 shows a state in which the fluid flows into one side of the first pipe 110 and the fluid flows out to the other side of the first pipe 110. However, depending on the arrangement of the partition 150, the second pipe 120 The fluid flows into one side of the first pipe 110 and the fluid flows into the other side of the second pipe 120 so that the fluid flows into one side of the first pipe 110, The fluid may flow into one side of the first pipe 110 and the fluid may flow out to the other side of the second pipe 120.

As shown in FIG. 5, the heating unit 100 of the electric boiler using the Pettis device according to an embodiment of the present invention may include a connecting pipe 160 and a cap 170.

The connection pipe 160 is connected to the side where the fluid flows into the heating unit 100 and the side where the fluid flows out from the heating unit 100 and the stopper 170 is connected to the connection pipe 160 . That is, the stopper 170 prevents the fluid entering the heating unit 100 from flowing out to a place other than the connection pipe 160. The connection pipe 160 is connected to one side of the circulation pipe and one side of the heating unit 100, the other side of the heating unit 100, one side of the fluid tank 200, The other side of the circulation pipe may be connected to the other side to form a circulation path through the heating unit 100, the fluid tank 200, and the circulation pipe.

At this time, the first pipe 110, the second pipe 120, the flat tube 130, and the PTC device 140 may be coupled to each other in a state where the first pipe 110, the second pipe 120, It is preferable to cover the heating unit 100 and it is preferable to cover the electric boiler using the Pettis device according to an embodiment of the present invention.

The controller 400 of the electric boiler using the Pittsy element according to an embodiment of the present invention supplies power for a predetermined power supply time during a predetermined initial drive time and repeats the power supply for a predetermined power off time And then supplies a constant power after the initial driving time.

The temperature of the Pittsi device 140 may be maintained within a predetermined range after a certain temperature even if the power source is applied. However, there is a possibility that an overcurrent may be generated during the initial power supply, thereby damaging the electric wires or the control circuit.

It is preferable to supply power for a predetermined power supply time out of a predetermined initial drive time and shut off the power supply for a predetermined power off time to protect the line and the control circuit due to the overcurrent. For example, if the initial drive time is set to 30 seconds, the power supply time is set to 0.5 second, and the power off time is set to 2 seconds, the power is turned off for 0.5 seconds, The cycle can be repeated. That is, when the first power is applied, the power can be supplied without interruption after the temperature is raised to about 200 degrees by repeatedly performing the power-off for 0.5 seconds for 30 seconds and for 2 seconds for the power-off.

As shown in FIG. 1, the controller 400 of the electric boiler using the Pittsy's element according to an embodiment of the present invention controls the temperature of the fluid or the fluid until the temperature of the fluid or the fluid is raised to a predetermined temperature And the motor of the circulation pump 300 is decelerated.

For example, the motor may be set to decelerate about 50% until the temperature of the Pittsy device 140 rises to about 200 degrees, and the motor may be decelerated until the temperature of the fluid rises to about 60 degrees. have. It is also possible to set different degrees of deceleration of the motor depending on the temperature.

In the case of a 30 pyong boiler, 40 to 50 kW of electric power is consumed in a general electric boiler, but electric power of 4 to 5 kW is consumed in an electric boiler using a pettish device according to an embodiment of the present invention.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
