Portable gas range capable of supplying liquid fuel {PORTABLE GAS RANGE CAPABLE OF SUPPLYING LIQUID FUEL}

The present invention relates to a portable gas range, and more specifically, it is possible to supply a liquid fuel that can maintain a strong thermal power continuously over time, and maintain a constant thermal power until all liquid fuel remaining in the gas cylinder is consumed. It relates to a portable gas range.

In general, a portable gas range is a gas ignition device that can be used while being portable due to its small volume, and is a cookware that is useful not only indoors, but also indoors, such as at homes and businesses.

The main fuel charged in the gas cylinders is flammable liquefied butane gas, which is contained in natural gas or petroleum cracking gas, and exists as a colorless gas under normal temperature and normal pressure. If present, it has the property of being easily burned.

In the gas cylinder of a conventional portable gas range, most of the liquid fuel is stored, and the remaining upper space is partially filled with gas fuel in which the liquid fuel is vaporized. Conventional portable gas ranges use this gas fuel to generate thermal power.

However, the conventional portable gas range has relatively good thermal power because the internal pressure applied to the vaporized gas fuel is large in the initial state where the liquid fuel is sufficiently inside the gas cylinder, but the liquid fuel decreases and the internal pressure decreases over time. There is a problem in that the supply is not smooth and the thermal power is gradually reduced.

The rotating ring 400 is coupled to the outer circumferential surface of the connection cap 130, and a rotating handle 401 is mounted on one side to rotate the gas cylinder 110 based on a longitudinal axis (forward and rear axis). That is, the gas cylinder 110 is inverted up and down according to the operation of the rotary ring 400 may be switched from the gas fuel (G) supply to the liquid fuel (L) supply.

3 is a cross-sectional view schematically showing the interior of a gas cylinder according to an embodiment of the present invention. Specifically, FIG. 3(a) is a view showing an initial state in which the gas cylinder is seated in the fuel supply unit, and FIG. 3(b) is a view showing a state in which the gas cylinder is inverted up and down according to the operation of the rotary handle.

As illustrated, most of the liquid fuel L is stored inside the gas cylinder 110, and the gas fuel G in which the liquid fuel is vaporized is partially filled in the remaining upper space. The conventional portable gas range generates a thermal power by using such gaseous fuel (G), while the portable gas range according to the present invention differs in that it can generate thermal power by using even liquid fuel (L).

The nozzle 111 having the injection end 112 and the discharge end 113 is coupled to the front side of the gas cylinder 110. The injection end 112 is bent to extend perpendicular to the discharge end 113. That is, the discharge end 113 is disposed in the same direction as the longitudinal direction of the gas cylinder 110, and the injection end 112 is disposed orthogonal to the longitudinal direction of the gas cylinder 110.

A seating groove 114 is formed on the front outer circumferential surface of the gas cylinder 110 so as to engage the container guide 403 formed protruding from the rotating ring 400. The injection end 112 is disposed to face the seating groove 114 direction.

As shown in Figure 3 (a), when the gas cylinder 110 is in an initial state seated on the fuel supply unit 100, the seating groove 114 and the injection end 112 are arranged to face upward, the gas cylinder 110 The gas fuel G is supplied to the gas combustor 210 through the connection cap 130 and the syringe needle tube.

As shown in Figure 3 (b), when the rotating ring 400 is rotated according to the operation of the rotating handle 401, the upper and lower sides of the gas cylinder 110 are reversed, the seating groove 114 and the injection end 112 are lower It is arranged to face, and the liquid fuel (L) inside the gas cylinder 110 is supplied through the connection cap 130 and the syringe needle tube.

The liquid fuel L supplied through the connection cap 130 is discharged to the vaporizer 220 through the first syringe needle tube 311, the gas valve 310 and the second syringe needle tube 312, which will be described later. , It is converted from the vaporizer 220 to vaporized fuel by the heat of the gas combustor 210, and is supplied to the gas combustor 210 after passing through the supply pipe 250 and the gas regulator 120.

At this time, the gas cylinder 110 may be mounted so that the rear side is lifted upward by a predetermined angle (for example, about 3 degrees) so that all of the liquid fuel L remaining therein can be consumed. For comparison, a virtual horizontal line (dashed line) is shown in the drawing.
First, when the light is turned on in the portable gas range, gaseous fuel (G) inside the gas cylinder 110 is supplied to the gas combustor 210 through the syringe needle tube, so that the light is turned on. When the gas combustor 210 is turned on, the gas cylinder 110 is rotated so that the liquid fuel L is sent to the vaporizer 220 through the syringe needle tube, and the liquid fuel L is vaporized fuel by the heat of the gas combustor. While being supplied to the gas combustor 210, combustion continues.
First, when combustion starts, a small amount of gaseous fuel (G) is supplied through a thin syringe needle tube, so that the flame is lightly turned on to the gas combustor 210. Then, when the liquid fuel L is supplied by rotating the gas cylinder 110, a large amount of vaporized fuel is supplied from the vaporizer 220 to the gas combustor 210 due to the high density of the liquid, so that the thermal power becomes stronger.
At this time, the reason for turning on the gas combustor 210 by supplying gaseous fuel G at the start of combustion is that combustion is impossible with the liquid fuel L. Accordingly, at first, gas fuel (G) is supplied to generate a weak flame, and liquid fuel (L) is vaporized from the vaporizer 220 using this initial thermal power, and then supplied to the gas combustor 210 for combustion.

4 is a view showing a state of the fuel supply unit according to an embodiment of the present invention.

As shown, a reciprocating lever 150 is mounted on the inner surface of the fuel supply unit 100. The reciprocating lever 150 is moved back and forth according to the operation of the detachable handle 140, and accordingly the gas cylinder 110 is also moved back and forth.

The container guide 403 is rotated from the top to the bottom according to the rotation of the rotating ring 400, and the gas cylinder 110 is also rotated from the top to the bottom. As the rotating ring 400 rotates, the fixed iron core 404 is rotated from right to left to contact the one-way clutch 151.

As illustrated, in the initial state, the reciprocating lever 150 is pushed backward. In this state, when the user inserts the gas cylinder 110 and pulls the detachable handle 140 downward, the reciprocating lever 150 advances and the contact portion 153 pushes the rear center of the gas cylinder 110 to push the gas cylinder 110. The nozzle 111 of the is connected to the connection cap 130. The gas fuel G inside the gas cylinder 110 is supplied to the gas valve 310 through the first syringe needle tube 311 coupled with the connection cap 130.

Then, when the gas combustor 210 is ignited and the user grasps and rotates the rotation handle 401, the rotating ring 400 rotates and the top and bottom of the gas cylinder 110 are reversed, and the liquid fuel inside the gas cylinder 110 ( L) is supplied to the gas valve 310 through the first syringe needle tube 311. The rotating operation process of the rotating ring 400 will be described in more detail below.

As the rotating ring 400 rotates, the fixed iron core 404 protruding to the outside also rotates, and the fixed iron core 404 slightly pushes the one-way clutch 151 to move backward, and then passes through the one-way clutch 151. So it is put on the top.

When the rotating ring 400 is completely rotated, the fixed iron core 404 is blocked by the one-way clutch 151, so that the rotating ring 400 is temporarily stopped without being restored to the original shape, and the inside of the gas cylinder 110 continues. Liquid fuel L may be supplied.

5 is a view showing a state of the valve assembly according to an embodiment of the present invention. Specifically, FIG. 5(a) is a view showing a valve assembly according to an embodiment of the present invention as viewed from the top, and FIG. 5(b) is a view of a valve assembly according to an embodiment of the present invention as viewed from the bottom. It is a diagram showing.

The valve lever 320 is mounted to be able to rotate up and down based on the valve shaft 321, and the lower end thereof is connected to the outlet side of the gas valve 310 to open and close the gas valve 310. When the valve lever 320 is rotated downward, the outlet side of the gas valve 310 is opened while being pulled.

The valve handle 330 is disposed so as to wrap the outer side of the valve lever 320, and is mounted to be rotatable based on the valve shaft 321. The end of the valve handle 330 is disposed relatively higher than the end of the valve lever 320, and a pressing piece 331 protrudes to the end of the valve handle 330 to press the upper end of the valve lever 320. Can be.

When the valve handle 330 rotates downward and the pressing piece 331 presses the end of the valve lever 320, the valve lever 320 temporarily rotates downward, and accordingly the gas valve 310 temporarily Is open.

The valve opening portion 340 is connected to the upper portion of the valve lever 320 and rotates the valve lever 320 to perform a function to maintain the gas valve 310 in an open state. When the valve opening portion 340 is moved to the right, the valve lever 320 rotates downward, and thus the gas valve 310 is opened.

Meanwhile, an electromagnet is built in the valve opening portion 340 to allow the valve opening portion 340 to move left and right. The electromagnet is electrically connected to the thermocouple 240, and the thermocouple 240 senses the heat of the gas combustor 210 and operates by the converted current (see FIG. 2).

In other words, the gas valve 310 is normally closed, but when the user rotates the valve lever 320 by operating the valve handle 330, it is temporarily opened (used during initial ignition), or The electromagnet connected to the thermocouple 240 is operated by the heat of the gas combustor 210 to open when the valve lever 320 is rotated as the valve opening 340 moves to the right (use after ignition).

When no force is applied to the rotation handle 401, the reciprocating pipe 420 maintains the state moved to the left by the elastic force of the original spring 440, and the user holds the rotation handle 401 and rotates the rotation ring. When the 400 is rotated, it is pulled by the rope 430 to overcome the elastic force of the original spring 440 and moves to the right.

Of course, when the thermal power is provided and the motion stop of the rotating ring 400 is released, the reciprocating pipe 420 moves to the left again by the elastic force of the original spring 440 to return to the original state, and the rotating handle 401 also returns to its original position. Return to.

Meanwhile, one side (the rear side in the illustrated embodiment) of the steering lever 450 is connected to the reciprocating pipe 420. The control lever 450 is mounted to be able to rotate clockwise or counterclockwise relative to the control shaft 451, and rotates by interlocking according to the operation of the reciprocating pipe 420.

Specifically, the heat insulation part 500 is disposed on the vertical surface 510 that blocks between the fuel supply part 100 and the combustion part 200, and is flat on the upper part of the fuel supply part 100 to cover the upper part of the gas cylinder 110. It may include a surface 520 and an inclined surface 530 connecting between the vertical surface 510 and the flat surface 520 (see FIG. 2 ).

At this time, the flat surface 520 and the upper end of the trivet 260 is preferably disposed to have the same height. That is, in the present invention, even if a cooking appliance having a large heating area such as a meat plate is used (excess plate), the flat surface 520 can cover the upper portion of the gas cylinder 110 to prevent heat from being transferred to the gas cylinder 110. It is effective in preventing safety accidents such as explosions and fires.

Hereinafter, an operation process of a portable gas range capable of supplying liquid fuel according to an embodiment of the present invention will be described.

8 is a view for explaining an initial state in which a gas cylinder according to an embodiment of the present invention is seated in a fuel supply unit, and FIG. 9 is an example for explaining the overall operation of a portable gas range according to an embodiment of the present invention It is.

In order to use the portable gas range according to the present invention, the user first places the gas cylinder 110 on the fuel supply unit 100 and presses the detachable handle 140 installed on the front surface of the fuel supply unit 100 downward.

When the detachable handle 140 is operated, the reciprocating lever 150 on the inner surface of the fuel supply unit 100 moves forward, and the spherical contact portion 153 pushes the rear central portion of the gas cylinder 110 to the gas cylinder 110. The nozzle 111 is connected to the connection cap 130.

At this time, the seating groove 114, which is recessed on the front outer circumferential surface of the gas cylinder 110, is engaged with the container guide 403 protruding from the outer side of the rotating ring 400. In addition, the nozzle injection end portion 112 inside the gas cylinder 110 is disposed toward the upper portion in the same direction as the seating groove 114.

FIG. 10 is a view for explaining a state in which the thermal power adjusting handle and the valve handle are operated according to an embodiment of the present invention, and FIG. 11 is a valve lever according to an embodiment of the present invention blocking the control lever to rotate the gas cylinder. It is an example to explain the state that cannot be.

As shown, when the nozzle discharge end portion 113 of the gas cylinder 110 is connected to the connection cap 130, the user presses the valve handle 330 while turning the thermal power adjusting handle 121, the gas combustor 210 is ignited. And fires (initial ignition).

At this time, since the injection end 112 of the gas cylinder 110 is disposed toward the upper side, the gas fuel G inside the gas cylinder 110 is supplied to the first syringe needle tube 311.

Then, when the user presses the valve handle 330, the pressing piece 331 at the end of the valve handle 330 presses the upper portion of the valve lever 320 to rotate the valve lever 320 downward, and the gas valve 310 )'S outlet side is pulled open.

When the outlet side of the gas valve 310 is opened, the gas fuel (G) injected into the gas valve 310 is the second syringe needle tube 312, the vaporizer 220, the supply pipe 250 and the gas regulator 120 It is supplied to the gas combustor 210 through and is ignited by the spark of the igniter 230.

Since the first syringe needle pipe 311 and the second syringe needle pipe 312 are thin tubes having a relatively small diameter compared to the diameter of the supply pipe 250, the supply amount of gaseous fuel G is small in the initial state. Weak firepower is provided.

12 is a view for explaining a state in which the rotary handle according to an embodiment of the present invention is operated, and FIG. 13 is a valve opening unit having an electromagnet according to an embodiment of the present invention operated to allow the steering lever to rotate Accordingly, it is an exemplary view for explaining a state in which the rotation handle and the gas cylinder can rotate.

As illustrated, after the gas combustor 210 is ignited initially, in order to provide more powerful firepower, the user holds the rotation handle 401 and rotates the rotation ring 400.

When the rotating ring 400 is rotated, the seating groove 114 engaged with the container guide 403 protruding from the rotating ring 400 is rotated, and through this process, the gas cylinder 110 is rotated to invert the top and bottom. . At this time, since the injection end 112 of the gas cylinder 110 is disposed toward the bottom, the liquid fuel L inside the gas cylinder 110 is supplied to the first syringe needle tube 311.

Meanwhile, the reciprocating pipe 420 connected through the rotation handle 401 and the rope 430 by the rotation of the rotating ring 400 also moves to the right, and the steering lever 450 connected to the reciprocating pipe 420 is steered. Rotate clockwise with respect to the shaft 451.

At this time, since the initial power is already supplied to the gas combustor 210, the electromagnet is operated by the current converted by the thermocouple 240, and the valve opening 340 is moved to the right by the operation of the electromagnet to move the valve lever. Maintain the rotated state 320.

Therefore, the rotation stopper 452 formed on the front side of the control lever 450 can pass freely without being caught by the right end of the valve lever 320, and accordingly, the rotation handle 401 can also rotate freely.
That is, the control lever 450 is a device that controls the rotation of the gas cylinder 110. When the gas combustor 210 is turned on, the gas cylinder 110 may rotate, and the gas combustor 210 is turned off. If present, the gas cylinder 110 is a device that stops rotation from rotating.
As shown in FIG. 11, when the gas combustor 210 is turned off, the gas valve 310 is closed and the valve lever 320 is raised to block the control lever 450, so the control lever 450 cannot move and the gas cylinder The rotation of 110 is also blocked.
Conversely, as shown in FIG. 13, when the gas combustor 210 is lit, the gas valve 310 is opened and the valve lever 320 is lowered so as not to block the control lever 450, so the gas cylinder 110 It will be able to rotate. Accordingly, the liquid fuel L inside the gas cylinder 110 may be supplied to the vaporizer 220 and vaporized before being combusted.
As described above, the reason for controlling the rotation of the gas cylinder 110 using the above-described steering lever 450 is that the liquid fuel L is never turned toward the gas combustor 210 while the gas combustor 210 is not lit. This is to prevent it from flowing. When the gas combustor 210 is not lit, the liquid fuel L continuously flows toward the gas combustor 210, which may cause a great danger.
In other words, the control lever 450 is a very important safety device that controls the rotation of the gas cylinder 110.

After the rotating ring 400 is completely rotated, the fixed iron core 404 protruding from the outside of the rotating ring 400 is placed on the upper part of the one-way clutch 151 so that the rotating ring 400 rotates even if the user releases the hand. You can keep the state.

The liquid fuel L supplied from the gas cylinder 110 passes through the first syringe needle tube 311, the gas valve 310 and the second syringe needle tube 312 and is delivered to the vaporizer 220. The liquid fuel L transferred to the vaporizer 220 is rapidly vaporized by the heat of the adjacent gas combustor 210 and converted into vaporized fuel.

The vaporized fuel is delivered to the gas regulator 120 through the copper supply pipe 250, and then supplied to the gas combustor 210 through another supply pipe 250 connecting the gas regulator 120 and the gas combustor 210. And burns.

As described above, the present invention has the advantage of being able to supply the gas combustor 210 by utilizing the liquid fuel L which is relatively denser than the gas fuel G, so that it can continuously maintain strong firepower.

In addition, since the present invention can be used as the liquid fuel (L) almost without vaporization inside the gas cylinder 110, there is no cooling action of the gas cylinder 110, and the thermal power is constant at a constant pressure until all liquid fuel is consumed. Can provide.

Furthermore, since the present invention can use the liquid fuel L remaining in the gas cylinder 110 until it is completely consumed, there is almost no economic waste due to the replacement of the gas cylinder 110, and it is safe even when disposed of and does not pollute the environment. There are advantages.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications and changes can be made without departing from the spirit of the present invention.
