Description

[0001] ALCOHOL STOVE USING ASCENDING FLOWS [0002]

More particularly, the present invention relates to an alcohol heating apparatus using upflow, and more particularly, to an apparatus and a method for controlling an alcohol heating apparatus using upflow, And an alcohol heating device capable of lowering the risk of fire by minimizing heat transfer to the lower part where the flame is transferred to the upper part by the rising pressure of the high pressure and the fuel is supplied.

It is already known that a petroleum furnace is used in which the core can be moved up and down, the oil is supplied from the oil tank to the core, and the capillary phenomenon of the wick is utilized to suck and supply the oil to the combustion portion.

In the deep-fired petroleum hearth, a portion where the flame is generated and a portion where the flame goes up are separated. The inner part of the flame is located in the innermost part of the flame, and there is a wick in which the wick is wrapped from the inside to the outside, and a core wick that wicks the wick upside and down while wrapping the outer surface of the wick.

Further, a wind deflector composed of a flattened disk having an outer diameter larger than that of the wick outer tube is placed above the flame generating portion. On top of the wind deflector, there is a condenser tube, which is mounted with a cross pin which combines a heat sink with a small inner diameter, an inner cylinder, an outer cylinder, and a transparent glass. On the upper surface of the inner cylinder, a cylindrical substrate having a plurality of air holes is attached horizontally. A large number of pores are formed in the inner salt tank, a large hole is formed in the outer salt tank, and a core is located in the lower portion corresponding to the space between the salt water passage and the outer salt tank.

In the above structure, oxygen supply through the inner cylinder top is insufficient, so that the amount of heat generated is inevitably small. Conventionally, there is a problem in that the pressure loss due to the cylinder substrate is increased because the cylinder substrate having the vent hole is directly attached to the inner cylinder. That is, even if a hole is formed in the cylinder substrate, the air passing through the inner cylinder is in close contact with the inner cylinder, and the pressure loss is increased due to a large resistance from the cylinder substrate, There were disadvantages.

In the apparatus for controlling the calorific value of a petroleum hearth of Korean Utility Model Registration No. 20-0249626 (registered on Sep. 26, 2001), a cylinder board having a plurality of ventilation holes is disposed on the inner cylinder, as shown in FIG. 5, A bracket 3 is formed between the upper end of the tubular substrate 2 and the tubular substrate 2 so as to reduce a pressure loss and a flange 5 And the lower portion of the flange is in contact with the core inner cylinder 6 located inside the core.

The regulated utility model gun has a structure in which the space between the inner cylinder 1 and the cylinder substrate 2 is separated by the bracket 3 so that the air discharged from the existing inner cylinder passes directly through the cylinder substrate, And the supply of oxygen to the inner cylinder 4 is smoothly performed, so that the thermal power is increased.

However, since the air supplied to the salt tank in the new utility model is diffused in the inner salt tank, only a small amount of air is supplied directly to the wick, so that the increase in the thermal power is insufficient. In addition, even if the fuel is replaced with a volatile alcohol to increase the thermal power, since the airflow at the upper part of the core is low, alcohol volatilization can not be performed quickly and the thermal power increase effect is insufficient.

The alcohol heating device 10 according to the present invention may be designed to perform heating by using a fuel oil which is designed to be an alcohol fuel but is generally used for heating.

As shown in the figure, the heating device 10 according to the present invention is a heating device that absorbs fuel by capillary phenomenon of the wick and burns at an upper portion of the core to provide heat. The heating device includes a core drawing device 20, An apparatus 30, and a fuel storage tank 40. As shown in Fig.

The core drawing apparatus 20 includes a core drawing body 21 having a U-shaped cross-section tube body with an upper portion opened in an annular ring shape. That is, the core drawing body 21 is an annular cylinder having an inner side wall and an outer side wall having different diameters, a lower end closed and an upper end opened. The opened upper end is formed with a wick out opening hole 211 to narrow the opening width of the upper end formed with the wick out opening hole 211 to prevent a gap between the wick and the inner and outer side walls from being generated, Otherwise, the fuel supply is interrupted. The interior of the core draw-out main body 21 is formed with a suction chamber 212 so as to secure a space at a constant height so that wicks can move up and down, and to collect a certain amount of fuel at the bottom. It is preferable that the intake chamber 212 does not have an empty space when the wick is minimized so that the supply of fuel is no longer provided. In addition, an air flow port 24 is formed in the center shaft of the wick extending body 21 to communicate with the outside to allow outside air to flow in. A pedestal 25 is formed at the lower end of the wick extending body 21, So that the outside air communicates with the air flow port 24 of the central shaft. The pedestal 25 may be provided with three or more support rods for stably supporting the core withdrawal main body or may be formed by combining the inner surface of the upper portion of the cylindrical body with the outer surface of the lower portion of the core withdrawal body, And the like.

The wick 22 which is installed in the wick extending body 21 so as to be able to move up and down is disposed in the wicking chamber 212 inside the wick extending body and is formed into a circular tube shape in accordance with the shape of the wicking chamber, Only a part of the upper end of the wick is protruded upward when the wick is drawn out by the wick-out hole 211 in the upper part of the body, and a considerable amount of wick is positioned in the wicking chamber so that the wicking of the supplied fuel is performed. The wick 22 may be made of glass fiber so that the wicking of the fuel can be facilitated or a variety of materials having high absorbability can be used. As shown in FIG.

As shown in FIG. 3, the wick control lever 23 may include a rotation lever portion 231 located at the front of the wick extending body, A rod 232 having one end fixed to the rotation lever part and the other end inserted into the suction chamber inside the wick body, and a gear part 234 installed at the end of the rod and rotated. In addition, the wick 22 is formed with an inclined groove 221 in a vertical direction on a part of its outer surface, and a gear stage 222 meshing with the gear portion 234 is formed on the upper side of the inclined groove, The wick can be rotated and moved upward or downward while being rotated. At this time, the lower end of the inclined groove is brought close to the lower end of the gear portion 234 in the inclined groove 221 of the core, thereby preventing the gear portion from being separated from the gear teeth.

The combustion device 30 is mounted on the wick lift device 20 to perform combustion and heat transfer. The combustion device 30 includes an inner furnace tube 31 and a furnace outer casing 32 forming a furnace, Is provided on the same axis by the engagement pin (34).

The lower end of the furnace inner cylinder 31 is positioned in the upper inner side edge of the core draw-out main body 21 so that the inner side communicates with the air flow port 24, So that the space communicated with the air flow port 24 is closed. A plurality of air inflow holes 312 are formed between the lower end of the inner wall of the furnace tube 31 and the portion where the induction partition plate is coupled to allow the air introduced through the air flow holes 24 to flow outside the furnace inner wall And discharged to be moved to the upper side. At this time, in order to lower the pressure of the air discharged through the air inflow hole 312, one or more through holes may be formed in the inductive partition plate 311. In addition, It is possible to minimize the resistance in the flow of air in the process of discharging the air introduced into the air flow port to the air inflow holes on both sides. In addition, when a through hole is formed in the induction partition 311, a large number of through holes are formed in the inner surface of the inner wall of the inner wall of the inner wall of the inner wall of the inner wall of the inner wall of the wall, So that combustion can be performed. When the inductive diaphragm 311 is formed, the air introduced through the air flow port 24 is discharged through the air inflow hole 312 having a narrow cross-sectional area formed in the inner wall of the furnace, so that the air passing through the air inflow hole is discharged at a high pressure And the high pressure ascending air flow further increases the wicking speed of the wick, so that the thermal power of the heating device can be increased.

Next, the furnace outer casing 32 includes the furnace inner tube 31, and is positioned at the upper outer edge of the core drawing body 21 to form a furnace 35 which is a space separated from the inner furnace inner tube 31 . A plurality of through holes are formed in the outer surface of the furnace outer tube 32 to continuously supply the outside air to the flame that goes up through the furnace to complete the combustion of the fuel.

The flame retarding cylinder 33 is for preventing the flame which can be discharged through the through hole of the inner flame outer cylinder from being exposed to the outside. A knob 331 is formed on one side of the flame retarding cylinder 33, 33 and the hearth outer tube 32 and the inner furnace tube 31 at the same time so as to light the wick 22. In addition, a dome-shaped dome 332 is formed at the upper end of the flame-proofing cylinder 33, and the dome net is heated by the heat transmitted through the furnace, so that the heat can be diffused and foreign substances can be prevented from flowing into the combustion apparatus .

The combustion apparatus 30 having the above-described structure may further include a diffusion truncated cone 313 at the upper end of the inner wall of the furnace. The diffusion truncated cone 313 diffuses with the upward inclined surface from the upper end of the inner furnace tube 31 and expands the heat discharged from the furnace 35 to the outside to maximally be discharged to increase the heating area. The diffusion truncated cone 313 may be fitted in a cap shape at the upper end of the inner wall of the furnace, or may be installed by welding or fastening. As shown in the figure, the upper portion may be formed as a receiving portion, May be cut in an inclined plane.

The fuel storage tank 40 is located at one side of the combination of the core drawing device 20 and the combustion device 30 and is configured to inject the fuel stored in the fuel storage tank through the fuel supply pipe 41 into the intake chamber 212, respectively. At this time, in a state where the wick is partially drawn out from the wick extending body, a space is secured in the wicking chamber 212, so that more fuel is supplied and wicking through the wick can be easily performed. The fuel storage tank 40 is separated from the combustion device 30 in order to minimize heat transfer to prevent ignition or explosion of the fuel storage tank due to heat.

In addition, the fuel supply pipe 41 may be provided with an intermittent valve 42 to arbitrarily intermittently supply fuel. That is, since alcohol is typically used as the fuel, alcohol is volatilized due to the strong volatility of the alcohol even if the wick is not drawn to the upper portion of the wick-out main body, so that the fuel supply to the wick-out main body 21 is blocked will be. Such an intermittent valve 42 can be installed in the fuel supply pipe 41 at a position as close as possible to the take-out main body 21 so as to minimize the amount of fuel supplied to the wick after the fuel supply pipe is cut off.

In addition, the fuel supply pipe 41 may be filled with a fiber material having hygroscopic property so that the fuel is supplied to the suction chamber of the core drawing body by capillary phenomenon, thereby minimizing or preventing the volatilization of the fuel in the unburned standby state .

In the meantime, the alcohol heating device of the present invention provides heating by natural winds, but it can be further installed with a blowing fan 50 to forcibly flow outside air. For example, as shown in FIG. 4, the blowing fan may be installed in the air flow port 24 on the central shaft of the core drawing main body 21 so that the outside air is supplied from the bottom to be supplied to the upper side, A blowing fan may be installed between the lower ends to allow for forced inflow of outside air.

1, the alcohol heating apparatus 10 according to the present invention includes a bottom plate 60, which is disposed on one side of the bottom plate to house a combination of the core withdrawal device 20 and the combustion device 30, The fuel storage tank 40 can be placed and then connected to the fuel supply pipe 41. In addition, the core drawing device 20 is enclosed by the safety case 61, and a safety net 62 is installed in the upper part of the safety case so that the heat generated in the combustion device is discharged to the outside, So that it can be prevented from being directly applied to the drawing device or the combustion device.

A brief description will be given of an operation state of the alcohol heating apparatus constructed as described above.

The alcohol which is the fuel stored in the fuel storage tank 40 is discharged through the fuel supply pipe 41 to the wick extracting apparatus (not shown) by opening the intermittent valve 42 first and then turning the wick adjusting lever 23, 20 into the wicking chamber 212 in the wicking body 21, and the supplied alcohol is picked up by the wick 22 to be ignited at the time of ignition.

The air introduced into the air flow port 24 of the center shaft of the core drawing device 20 is moved upward and blocked by the inductive partition plate 311 so that the air is guided through the air inflow hole 312 formed in the inner wall of the furnace 31 And is introduced into the furnace 35. Since the cross-sectional area of the air inlet hole 312 is smaller than that of the air flow hole 24, the air passing through the air inlet hole 312 is supplied to the furnace 35 while forming a high-pressure rising current.

Accordingly, a high-pressure rising flow due to air is formed in the upper space adjacent to the flame formed wick. Such a high-pressure rising flow acts to attract a strong suction force to the lower portion of the furnace, thereby further promoting alcohol evaporation of the wick 22, It is possible to increase the combustion power due to the increase of the amount of air and the increase of the amount of the introduced air.

The flame and the heat with enhanced firepower are moved upward through the furnace 35 and are diffused outwardly by the diffusion truncated cone 313 while being discharged to the upper end of the furnace. The diffusion of the flame and heat causes the dome net 332 to be heated through a large surface to achieve rapid heating.

In addition, in the heating apparatus having the additional blowing fan 50, a stronger upward air flow can be formed when the blowing fan operates, and the heating can be rapidly performed by increasing the combustion power.
