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, To provide an electric boiler using a Pettis device.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid circulation apparatus using a check valve,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid circulating apparatus using a check valve, and more particularly, to a fluid circulating apparatus using a check valve capable of circulating a fluid only by raising a temperature of a fluid using a check valve and a heating unit.

Generally, the type of heating and circulating fluid has been widely used in boilers, instantaneous water heaters, and the like. In the case of a boiler, for example, 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 the generated heat energy. Depending on the energy source, it is divided into oil boiler, gas boiler and electric boiler.

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.

In this way, various forms of heating and circulating fluid are used. At this time, most of the devices circulate the fluid using the pump. There is a problem that the impeller of the pump is damaged due to a foreign matter in the pipe or the like and the pump has to be replaced due to a failure of the motor or the like.

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)

The following drawings are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the following drawings, but may be embodied in other forms. In addition, like reference numerals designate like elements throughout the specification. It is to be noted that the same elements among the drawings are denoted by the same reference numerals whenever possible.

FIG. 1 is a conceptual view of a fluid circulating apparatus using a check valve according to an embodiment of the present invention, FIG. 2 is a perspective view of a fluid circulating apparatus using a check valve according to an embodiment of the present invention, 4 is a cross-sectional view taken along the line A-A 'in FIG. 2, and FIG. 5 is a cross-sectional view showing a connecting pipe and a cap coupled to each other in FIG.

1, a fluid circulating apparatus using a check valve according to an embodiment of the present invention includes a flow path portion 100, a check valve portion 200, a heating portion 300, and a control portion 400 .

The flow path portion 100 is formed with a flow path through which fluid can flow.

The flow path portion 100 corresponds to a section for heating the fluid while the fluid passes through the flow path portion 100.

A plurality of check valve units 200 are provided in the flow path unit 100 to control the flow of the fluid in one direction.

The check valve unit 200 can open and close a flow path formed in the flow path unit 100 and flow the fluid only in one direction and shut off the flow in the reverse direction.

At least two check valve units (200) should be installed in the flow path (100). This is to ensure that the sufficiently heated fluid flows out into the circulation pipe. Here, the circulation pipe refers to a pipe installed on the floor or wall so that heated fluid (hot water, etc.) flows for heating.

The check valve 200 may include an inlet check valve 210 and an outlet check valve 220.

The inflow check valve 210 is provided on the side where the fluid flows into the flow path portion 100 and flows the fluid into the flow path portion 100 to prevent the fluid from flowing backward.

The outflow check valve 220 is provided on the side from which the fluid flows out from the flow path portion 100 and flows out from the flow path portion 100 to prevent the fluid from flowing backward.

When the channel unit 100 is heated by the heating unit 300, the fluid inside the channel unit 100 is heated and the pressure inside the channel unit 100 is increased. Due to the increased pressure in the passage portion 100, the fluid in the passage portion 100 pushes the outflow check valve 220 and enters the circulation pipe. The fluid in the circulation pipe pushes the inflow check valve 210 and flows into the flow path portion by the force of the fluid flowing out of the flow path portion 100. By this process, a circulation path circulating the flow path portion 100 and the circulation pipe is formed.

That is, the fluid introduced into the flow path portion 100 flows upward through the flow path portion 100 until the fluid pushes the check valve portion 200, Lt; / RTI >

In addition, the check valve unit 200 may have a greater force for opening the check valve on the side where the fluid flows out than the force for opening the check valve provided on the fluid inlet side.

This is to facilitate the entry of fluid into the channel part 100 and to heat the fluid inside the channel part 100 until the fluid entering the channel part 100 is sufficiently heated.

5, the flow path unit 100 of the fluid circulating apparatus using the check valve according to an embodiment of the present invention includes a first pipe 110, a second pipe 120, a flat tube 130, And a partition 150. The partition 150 is formed by dividing a predetermined number of the flat tubes 130 into a first pipe 110 and a second pipe 120, 150 are provided so as to allow the fluid to pass through in a "d" shape.

The first pipe 110 is formed with a flow path through which the fluid can flow, and the second pipe 120 is formed with a flow path through which the fluid can flow. The first pipe 110 is spaced apart from the first pipe 120 by a predetermined distance And the flat tube 130 is provided with a plurality of flow paths through which the fluid can flow by fixing the first and second pipes 110 and 120 at both ends thereof, A predetermined portion of the first pipe 110 and the second pipe 120.

The first pipe 110, the second pipe 120, and the flat tube 130 have flow paths through which fluids (water, etc.) can flow.

The fluid is moved along the flow path 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.

That is, when the pressure of the flow path portion 100 is increased by the heated fluid passing through the flat tube 130 of the flow path portion 100, the outflow check valve 220 is pushed and the fluid is moved to the circulation pipe.

The reason for allowing the fluid to pass through the flow path portion 100 in the shape of "d" is to make the flow length of the fluid long enough to sufficiently heat the fluid from the heating portion 300. 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.

5, the flow path unit 100 of the fluid circulation apparatus using the check valve according to an embodiment of the present invention may include a connection pipe 160 and a stopper 170.

The connection pipe 160 is connected to the side where the fluid flows into the flow path portion 100 and the side where the fluid flows out from the flow path portion 100. The plug 170 is connected to the connection pipe 160, . That is, the stopper 170 prevents the fluid entering the channel portion 100 from flowing out to a place other than the connection pipe 160. In other words, the connection pipe 160 is connected to one side of the circulation pipe and one side of the circulation pipe to form a circulation path through the circulation pipe 100 - circulation pipe.

6, the flow path unit 100 of the fluid circulating apparatus using the check valve according to an embodiment of the present invention includes a first pipe 110, a second pipe 120, a flat tube 130, And a control unit.

In the embodiment described above with reference to FIGS. 2 to 5, an example of connecting in a parallel manner has been shown. However, the example shown in FIG. 6 is an example of being connected in series.

6, a fluid circulating apparatus using a check valve according to an embodiment of the present invention (see FIG. 6) is connected in series with a check valve To increase the heating ability.

The heating unit 300 is provided adjacent to the flow path unit 100 and generates heat by application of power.

The heating unit 300 may be provided to surround the outside of the flow path (see FIG. 1), or may be provided on the outside surface of the flow path (see FIGS. 2 to 6).

The heating unit 300 includes a PTC device. The heating unit 300 is disposed between adjacent two flat tubes 130 and generates heat to a predetermined temperature by an applied power source .

Positive Temperature Coefficient (PTC) is a positive characteristic thermistor. It is a barium titanate (ceramics) semiconductor device that has a high electrical resistance when temperature rises. It is a safe heating element instead of a nichrome wire. to be. 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 to the device, the device generates heat at about 200 to 250 degrees after about 30 seconds and maintains a constant temperature.

The use of the flat tube 130 as a tube is intended to widen the contact area with the Pitissi element when the Pitissi element is sandwiched between adjoining flat tubes 130, To heat the fluid in the tube effectively.

The spacing between the flat tubes 130 for fitting the Pitissi element is preferably in consideration of the thickness of the Pitissi element, and is preferably maintained at 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.

At this time, the first pipe 110, the second pipe 120, the flat tube 130, and the heating unit 300 may be wrapped around the heat insulating material in a state where they are coupled to each other, It is preferable to casing the unit 100, and it is also preferable to cover the entire electric boiler using the Pettis device according to an embodiment of the present invention.

The controller 400 controls the power applied to the heating unit 300.

Since the heating unit 300 is driven by power and must be driven according to the temperature setting, the time setting, the season setting, and the hot water setting, the controller 400 controls the temperature setting, the time setting, And controls the power supplied to the heating unit 300 according to the setting of hot water only.

The control unit 400 may apply power to the heating unit 300 when at least one check valve unit 200 of the check valve unit 200 is closed.

When the check valve on the side of the flow path portion 100 on which the fluid flows is closed, the pressure in the circulation pipe is lowered, and the fluid in the flow path portion 100 must be heated to increase the pressure in the circulation pipe. When the check valve on the side where the fluid flows out of the flow path portion 100 is closed, the pressure in the flow path portion 100 is lowered. In order to increase the pressure in the flow path portion 100, Lt; / RTI > That is, the fluid in the flow path portion 100 must be heated regardless of which check valve is closed.

The control unit 400 repeatedly performs power supply to the heating unit 300 during a predetermined power supply time during a predetermined initial driving time and interrupts the power supply for a predetermined power cutoff time, And power is supplied.

In the case of using the PITTICE device, even if the power supply is applied, the temperature is maintained within a certain range after a certain temperature, but over current may occur 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.

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.
