Description

Portable Gas Burner with Hinge Structural Configuration

Portable gas burners are easy to carry and are used for outdoor leisure time and for easy cooking. There are two types of portable gas burners, which are widely used at present. One is a gas burner having a very simple structure for carrying on mountain climbing, and the other is a rectangular gas burner commonly called 'Burstar'. . In the former case, it is composed of a burner part on which a cooking vessel is placed, a leg structure configured to be able to be folded and unfolded in order to reduce the volume, and a gas hose of a rubber type which is freely deformed for connection to the gas container and gas supply. do. This type of gas burner has an adapter in the rubber hose and is connected to the gas container manually, and there is no ignition device mounted on the gas burner, so that the ignition is usually performed by a separate lighter. And in order to minimize the volume and weight, there is an inadequate side to use a large bottom-shaped cooking container because the leg portion is weak and the burner portion is narrow in area. In addition, as a case of using a gas container with a wide base and a low height, a gas burner having a shape that utilizes the gas container itself as a leg structure for supporting the burner part may be regarded as this category.

The latter 'Burstar' shaped gas burner has a gas container accommodating part and a burner part accommodating the gas container, and has a relatively wide area for supporting the cooking container compared to the former case, resulting in a sense of stability. It is equipped with an ignition device for convenient use. Due to this advantage, in using the latter gas burner which is widely used at home or outdoors, the gas container sometimes overheats and explodes. This is mainly caused when the bottom of the cooking vessel is large, when the cooking vessel is heated in the burner part, heat radiated from the cooking vessel is transferred to the gas vessel, resulting in overheating of the gas vessel, resulting in an increase in the internal pressure of the gas vessel. will be.

Safety devices have been developed to prevent the explosion of gas burners. The devices are classified into 'detachable container' and 'euro blocker'. When the internal pressure of the gas container reaches a dangerous pressure, the 'detachable' safety device disconnects the gas supply by discharging the gas container from the inlet of the portable gas burner. The gas supply is stopped by mechanically blocking the flow path. In this case, the safety device of the method is through the Republic of Korea Utility Model No. 20-0240713 and Publication No. 2003-0082234 in the case of 'detachable container', and in the case of 'Euro Blocking Type' Patent No. 2003-0090920 has been disclosed, respectively, the development to improve the performance of the safety device is continuously being pushed.

However, even when the above-mentioned safety devices are used, in the situation where the gas container is overheated by the cooking vessel having an excessive floor area, the possibility of malfunction or failure of the safety device is sometimes inevitable. The gas burner's safety device is not activated and the gas container may explode, resulting in the loss of valuable lives. Therefore, technical advancement is required.

The present invention is designed to fundamentally solve the problems as described above, the object of the present invention, even when using a cooking vessel with a relatively large floor area compared to the size of the gas burner receives the radiant heat from the cooking vessel gas container It is to provide a gas burner having a hinge structure that can increase and adjust the distance between the burner portion and the gas container accommodation portion so that the heating is not overheated essentially.

Looking at the structure of the conventional gas burner of the 'Burstar' shape, the burner portion for supporting and heating the cooking vessel occupies a relatively large portion, the gas container receiving portion is relatively small on one side Occupies. Looking inside the gas burner, it can be seen that only the copper pipe for supplying the gas and the ignition wire is connected between the burner part and the gas container receiving part. That is, if only the pipe for supplying the gas and the ignition wire can be connected, it can be seen that it is possible to separate the gas container receiving portion from the burner.

The present invention is based on the above fact to separate the structure of the conventional gas burner in which the burner unit and the gas container receiving unit are integrated, and to increase and adjust the distance between the gas container receiving unit and the burner unit according to the situation, It is provided with a hinge and a connecting structure on the outer wall of the gas burner. Conventional ignition wires are lengthened and partly fixed to the floor or wall, whereby the ignition device provided in the outer structure of the gas burner when the gas container receiver is rotated by the hinge or returned to its original position. The wires are provided so that the wires are not damaged due to the contact with the end faces of the holes through which the gas hose passes, or the interference occurs in the unfolding operation of the hinge structure surface. At this time, the hole cross section is provided to finish the finish so that the sharp portion does not exist, or to wrap the cross section in a separate material that is not sharp. The conventional copper pipe for gas supply is replaced with a gas hose made of flexible materials (rubbers, plastics, etc.). That is, by extending the length by replacing the gas hose with an adapter at an appropriate position of the conventional copper pipe, or by replacing the whole with a gas hose, as in the wire for the ignition device described above, some parts are properly fixed to the floor or wall surface. When the gas container receiving part rotates and is returned to its original position by the hinge structure, the rubber hose is damaged or the hinge structure surface is brought into contact with the ignition device wire provided in the gas burner's outer structure and the gas end passage hole. It is provided so that interference does not occur in the deployment operation. Especially for frequent rotational deployment and return operations, the wires and gas hoses are arranged and secured so that no damage occurs. In addition, the rotational deployment can be prevented from operating the freely hinged deployment function between the burner portion and the gas container receiving portion of the gas burner due to the hinged structure that is rotated and deployed during the storage or movement of the gas burner. It is provided with a locking device for fixing the hinge operation in the non-state.
