Description

PORTABLE GAS RANGE [0002]

The present invention relates to a portable butane combustor, and more particularly, to a butane gas container which can be used universally regardless of the type and size thereof, as well as being easily separated and flowed by an external force in a state in which the butane gas container is mounted And a portable butane combustor capable of improving convenience and efficiency of use.

Portable butane combustor is a combustor using disposable bomb (hereinafter referred to as "butane gas container") in the form of metal can filled with liquefied butane gas. It is easy to carry and easy to use, so food culture such as stew It is widely used for outdoor activities such as camping and fishing in Korea.

Such a mobile butane combustor can be classified into a cassette type, a direct coupling type and a separation type according to the state and the manner in which the butane gas container is fastened. The cassette type includes a cartridge which can be equipped with a butane gas container separately. It is used in a low pressure state through a governor (regulator) without directly connecting to the combustion unit. Directly connecting the butane gas container to the combustion portion In the separation type, a butane gas container is connected to the combustion section by a hose or the like.

In the butane gas container, a nozzle-type butane gas container into which butane gas is largely injected and a high-pressure gas (isobutane, propane gas, etc.) are injected depending on the structure and shape of the nozzle for supplying the kind of the filler gas and the gas Which can be divided into a threaded butane gas container.

Among them, the screw type butane gas container has a tendency of being attracted to a mobile butane combustor having a structure adopting an adapter for connecting the screw type butane gas container in a stable state even under unusual conditions such as a high temperature zone and a desert.

For example, in Korean Patent Publication No. 10-1326046, a butane gas container is mounted upside down so that the nozzle portion of the screw type butane gas container faces downward (to the ground), thereby minimizing the residual of fuel in the butane gas container In addition, since liquefied gas such as liquefied gas is discharged from the nozzle in a liquid state, liquefied gas in which two or more kinds of liquefied gas are mixed is vaporized at the same rate, so that the thermal power is kept strong regardless of the remaining amount of fuel A portable gas burner has been disclosed.

1, a conventional portable gas burner is composed of a burner body 10 having a burner portion at the upper portion thereof and an ignition and gas amount manipulation knob at the front portion thereof and a burner body 10 connected to the burner portion 10 via a adapter 11, A butane gas container 20 fixed to the lower surface of the burner body 10 and a guide surface 33 corresponding to the curling portion 21 at the lower end of the butane gas container 20, And a container mounting plate 30 on which a jaw 32 and an elastic piece 34 are formed and in which a storage portion 35 for storing the adapter 11 is formed.

However, due to the structural characteristics of supporting a part of the curling part 21 of the butane gas container 20, which is circular when viewed in plan, due to the elastic force of the elastic piece 34, the bonding force is inevitably lowered, There is a problem in that it can be easily separated.

The butane gas container 20 is detachably attached to the container mounting plate 30 with the nozzle portion thereof facing downward. Due to the structural characteristics of the container, the buttress gas container 20 is unfolded, There is a limit to inconvenience in use because it must be installed at a certain height for the IGT table or mounted on the IGT table (Iron Grill Table).

In recent years, a portable butane combustor capable of using both of them by using a separate connector regardless of the type of butane gas container has been highlighted. The conventional butane mounting plate 30 has a guide surface 33 formed in the container mounting plate 30, Since the jaw 32 and the elastic piece 34 can be mounted only with the screwed butane gas container 20, the nozzle type butane gas container having a relatively smaller diameter can not be used, have.
