Butane gas is a liquefied petroleum gas which is pressurized and liquefied into a small bomb when it is pressurized to about 2 atmospheric pressure at room temperature, and is widely used as a fuel for home or camp. Although the disposable liquefied butane gas is easy to carry and easy to use, it is widely used for cooking appliances and fireplaces for camping, but its filling amount is as small as 220 g, and when it is used for burning, heat of vaporization is generated to cool the gas cylinder, Butane gas has a problem that it does not vaporize when it is below 0 ℃, so there is no problem for summer cooking. However, when it is used outdoors in winter, the ambient temperature is low so that the container is cooled more quickly and is not easily cooked. It can be a more fatal problem for a fireplace.

For this reason, the calorific value of the camping hearth for liquefied butane gas currently circulated is about 1800 kcal / h which is the maximum, and if the gas is used in actual cold winter or the use time is increased, the gas cylinder is cooled down, Has a problem in that it can not be heated sufficiently because of the above-mentioned reason.

On the other hand, a conventional camping furnace using liquefied butane gas has a product which can be used only for a hearth or for cooking, but the characteristic of a product mainly having a small amount of heat due to characteristics of liquefied butane gas There is a lack of actual calories to use as a cooking utensil, and it is used as a supplementary function of warming rather than cooking.

The gas hearth used as a cooker using a disposable gas canister is disclosed in Patent Registration No. 20-0432469 (registered on Nov. 27, 2006) and Patent Application No. 10-2011-0103774 (filed on October 11, 2011) However, the registrant's new draft No. 20-0432469 suggests that when heating, the heating element is directed horizontally, and when the cooking is performed, the direction of the heating element is made inconvenient, and when changing the angle of the heating element, The butane gas liquid in the gas cylinder may be ejected, posing a problem in safety.

In addition, in the case of the above-mentioned Patent Application No. 10-2011-0103774, since the heating area of the heating element faces the front, sufficient heat can be emitted for use as a stove, but when it is used for cooking, the heating area of the heating element toward the top is small, There is a problem that it is not suitable for cooking.

Hereinafter, a gas fireplace combined with a portable gas range according to the present invention will be described in detail with reference to the accompanying drawings.

A portable gas range combined gas stove according to the present invention relates to a portable gas range combined gas stove which can be used as a gas stove while using a plurality of disposable liquefied butane gas canisters (two in the figure) 1 to 6 and a portable gas stove combined with a main body 10 of a gas stove and a protection net 11 composed of a plurality of horizontal bars so as to prevent the user's hands, A space for accommodating the liquefied butane gas cylinders 40 is formed at both sides of the rear side of the main body 10 and a fuel supply cover 12 for protecting the liquefied butane gas cylinders 40 from the outside is provided, 10 is provided with a heat radiation tube 21 for radiating heat generated from a burner and a communication pipe 22, A grill 14 which is heated by the heat received from the cylinder 22 to cook food and a knob 13 which can ignite the gas of the liquefied butane gas cylinder or adjust the amount of gas, A handle 15 and the like are provided so as to be easily moved. In addition, a stainless steel reflector capable of maximizing the heating efficiency is installed in the vicinity of the heat radiation tube (21) inside the front opening portion of the main body (10).

The structure in which heat is generated by a burner supplied with gas fuel of two liquefied butane gas cylinders (which can be expanded to two or more) and the heat is transferred to the heat radiation tube 21 and the communication 22 is shown in FIGS. 5 will be described as follows.

A liquefied butane gas cylinder 40 is disposed on both left and right sides of the rear surface of the main body 10 and a liquefied butane gas cylinder 40 is placed in both left and right sides of the main body 10, The gas cocks 51 on the left and right sides are connected in parallel through the connecting pipe 52 so that the two liquefied butane gas cylinders 40 supply the fuel to the burner 30 through the fuel supply pipe 53 . Here, a structure for supplying fuel to the burner such as the gas cock 51, the connecting pipe 52, the fuel supply pipe 53, the nozzle 54, etc. on both sides of the cylinder is referred to as a fuel supply section.

It is preferable that the structure in which the gas cocks 51 on the left and right sides are connected in parallel through the connection pipe 52 is connected in parallel to the part depressurized by the gas cock 51 for the purpose of safety. The connection part of the liquefied butane gas pipe is a high pressure part (about 2 kg / cm 2), but when it passes the regulator integrated with the gas cock 51, it becomes low pressure (about 0.03 kg / cm 2) ), The safety is secured rather than the normal high-pressure parallel connection by connecting the low-pressure portion passed through the regulator in parallel heat conduction. The safety according to the gas pressure is the same when the leakage does not occur regardless of the high pressure or the low pressure. However, when leakage occurs under certain circumstances, since the leakage amount is higher as the pressure is higher, connecting the low pressure portion in parallel is performed by connecting the high pressure portion in parallel It can be said that it is safer. In addition, the low-pressure part parallel connection method like the present invention is more advantageous in the round surface or the like than the parallel connection of the high-pressure part in the material of the connection part, the valve, and the seal method.

Since the structure in which the gas cocks 51 on both the left and right sides are connected in parallel through the connecting pipe 52 as described above is connected in parallel, two of the liquefied butane gas cylinders are always consumed at the same time. As a result, It is a structure that must be opened at the same time. However, when one of the first liquefied butane gas cylinders is installed, if there is no additional backflow preventive structure in the gas cock 51, the gas leaks to the opposite side, so that the gas does not flow back to the inlet of the two gas cocks 51, There is no problem of leaking to the opposite gas cock 51 even if only one liquefied butane gas cylinder is installed.

A burner 30 which receives fuel from the fuel supply unit and generates heat is connected to a nozzle 54 provided at an end of the fuel supply pipe 53 to receive fuel and to generate a flame generated in the burner 31 And a burner cover (31) having a structure capable of concentrating the heat radiation tube (21). It is preferable that the burner 30 has a Bunsen burner structure having a good heat radiation efficiency, a large amount of control of the calorie capacity, and low unstable combustion.

The heat radiation tube 21 is provided on the upper part of the burner cover 31 and has a hollow cylindrical shape having a predetermined height. A plurality of holes are formed in the outer circumference of the heat radiation tube 21 so that heat radiated from the heat radiation tube 21 can be easily radiated. .

The communication 22 is formed in the upper part of the heat radiation tube 21 in a height direction and has a hollow cylindrical shape having a predetermined height. A predetermined distance from the upper end of the communication pipe 22 is formed in the upper part of the communication pipe 22 And a grill 14 for holding a cooking utensil using the cooking utensil.

A heat shield plate 23 for blocking heat generated from the burner 30 is provided between an upper portion of the heat radiation tube 21 and a lower portion of the communication pipe 22, When the heat plate knob 23a is rotated 90 degrees, the heat shield plate 23 can be closed or opened so that the heat generated from the burner 30 can be prevented from being transmitted to the communication hole 22 Or pass through. The material of the heat radiation cylinder 21 is preferably a heat resistant stainless steel perforated mesh or iron chrome mesh net so that the internal heat can be easily radiated. The material of the communication pipe 22 is preferably a heat resistant stainless steel plate And the material of the heat shield plate 23 is preferably a heat resistant stainless steel plate.

When the heat shield plate 23 is closed, the heat generated from the burner 30 is not transferred to the communication passage 22 but only the heat is radiated inside the cylinder of the heat radiation tube 21, (See Figs. 5 (a) and 5 (b)), the heat is radiated from the heat radiation tube 21,

On the other hand, when the heat shield plate is opened, heat generated from the burner 30 is vertically transmitted along the communication pipe 22, and heat is transferred to the grill 14 and used as a gas range c) and (d)]. In this case, since the flame generated in the burner 30 does not reach the heat radiation tube 21, the heat radiation tube 21 is not heated up due to the communication effect and almost all heat is transmitted to the grille 14 will be.

In order to prevent the liquefied butane gas cylinder (40) from being overcooled by gasification of the gas during use of the gas, the present invention provides a heat conductive plate (62) having a certain thickness to receive heat generated through the burner So that the liquefied butane gas cylinder 40 is not cooled by the heat transferred to the heat conduction plate 62 so as to surround the liquefied butane gas cylinder 40.

As shown in FIGS. 4 and 6, the heat conduction plate 62 is provided with a heat conduction plate 61 heated by heat in the heat conduction tube 21 or heat passing through the heat conduction plate 61, And the heat conduction plate 62 is fixedly coupled to both sides of the heat conduction plate 62 so that the heated heat of the heating conduction plate 61 is transmitted to the left and right heat conduction plates 62. The heat conduction plate 62 is formed in a cylindrical band shape in which a portion is cut so that the liquefied butane gas cylinder 40 can be easily wrapped when the gas cylinder 51 is coupled to the gas cock 51.

In addition, the present invention provides an oxygen deficiency safety device (70) at a location adjacent to the burner (30) to prevent suffocation due to carbon monoxide when oxygen is deficient when used in a tent installed in an outdoors and indoors, The gas flowing into the burner 30 is blocked.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
