Description

TECHNICAL FIELD

[0001] The present invention relates to a portable direct fire grill which can easily grill and heat a grilled food material indoors and outdoors since it is portable. BACKGROUND

[0002] Generally, a grill is a device for cooking a grilled food material with heat, and is classified into a direct heating method using a flame of gas and charcoal and an indirect heating method using electricity according to a method of providing heat.

[0003] For example, a direct fire grill using charcoal in the direct heating method has a problem that an inside of a grilled food material is not completely cooked but only a surface thereof is scorched since a size of a flame is difficult to adjust, and a problem that flying ash and smoke are generated at the time of combustion, and as a method for solving these problems, a direct fire grill using butane gas is proposed.

[0004] That is, the direct fire grill using butane gas in the direct heating method has an advantage that the flame is easily adjusted, but in most of the grills, the flame is on a lower side of a grill plate for placing meat on the flame, and thus has a problem that smoke and toxic gas are generated due to a drip of a juice or oil generated from the grilled food material, and the grilled food material is easily stuck on the grill plate at the time of grilling, and the grilled food material is scorched, etc.

[0005] In order to solve these problems, a downward type grill generating a flame from an upper portion is proposed, such as Korean Published Patent No. 10-2012-0083169 (published on July 25, 2012) "Portable direct fire grill", and Registered Patent No. 10-1454356 (announced on October 23, 2014) "Portable stove and direct fire grill capable of being installed on a table", and Published Patent No. 10-2014-0146882 (published on December 29, 2014), and Registered Patent No. 10-1715572 (announced on March 22, 2017) "Bidirectional grill having a grill lifting structure", etc.

[0006] Such a downward type grill can improve a problem that smoke and toxic gas are generated due to a drip of a juice or oil generated from a grilled food material, and a problem that the grilled food material is easily stuck on a grill plate at the time of grilling, and in order to improve a problem that a grilling time is long as a problem of the downward type, although an elevator is provided to adjust a height of the grill plate, it is inconvenient to carry due to a complicated structure and a large volume, and has a disadvantage that it is limited to grilling using the grill plate.

[0007] Further, the downward type burner is disposed at an upper portion of the grill plate, and thus a burner structure has a limitation of not being resistant to heat due to convection heat.

[0008] Also, in order to carry, the burner structure can be a light metal material, in this case, there is a concern that the direct fire grill is damaged more directly by convection heat and also endangers human life.

[0009] The matters described in the above background section are provided to assist in a better understanding of the background of the application, and are included to disclose information that was known at the time of the application, and which might be used by a person of ordinary skill in the art.

[0054] Hereinafter, a portable direct fire grill according to an embodiment of the present application will be described with reference to the accompanying drawings. Figures 1 to 4

[0055] The portable direct fire grill of the present application includes a gas supply part 1 which accommodates a butane gas container in an accommodation chamber formed on the upper side of the rear end of the lower case 31, thereby discharging butane gas through an adjusting valve 12; a flame part 2 having a heating module which causes hot air of a flame, which is generated by discharging butane gas through the gas supply part 1 and combusting the butane gas toward the lower side of the upper case 21, to be downwardly emitted toward the lower case 31 of a grilling part 3; a heat-insulating container 23 which opens the upper case 21 and is installed at the upper end of the heating module through the opened part, so that the grilling food material can be heated by the hot air naturally released from the heating module; a grilling plate 32 which is divided into left and right side plates 321, 321' by being divided into two equal parts, a plurality of convex ribs 322 are formed on the upper grilling surface in order to discharge oil, oil dropping spaces are arranged between convex pieces 322' of the rib 322 parts at which the left and right side plates 321, 321' meet, and the convex pieces 322' and first fixing protrusions protruding on the upper end of the side surface of the left and right side plates 321, 321' are insertedly combined with guide grooves formed on both ends of the upper side of the lower case 31 and first fixing holes 13 formed on the upper side of the gas supply part 1, thereby functioning to cover the left and right side plates; a support 73 which is formed with a semicircular groove on the upper side, so that the lower side is insertedly fixed to the upper end of the latching part of the lower case 31 and can support the other end of the skewer support and the smoke exhaust pipe; a lid 4 which is formed with second fixing holes 14 perforated on both ends of the upper side of the gas supply part 1, latching holes formed on the front end of the upper case 21, and guide grooves formed on both ends of the lower side so that guide protrusions protruding from both ends are insertedly combined, and second and third fixing protrusions are formed inside the rear and front ends; and a handle 5 which is formed with first and second hinges protruding on both ends in order to be inserted into the lid 4 and rotated.

[0056] Further, a support frame 34 which places the left and right side plates 321, 321' of the oil receiving part and the grilling plate 32 is raised and lowered by means of a lifting part, so that the grilling food material approaches or is spaced apart from the heating module.

[0057] A more specific object of the present application is to protect the upper case 21 of the downward type portable direct fire grill as described above from convection heat.

[0058] Therefore, in the present application, a plurality of heat dissipation grooves are formed in the upper case 21, so that heat from the heating module inside the upper case 21 can be released to the outside through the heat dissipation grooves.​

[0059] The heat sink includes side heat sinks 21-1 and front heat sinks 21-2.

[0060] The side heat sinks 21-1 are formed on both sides of the upper case 21 in a manner extending in the length direction of the upper case 21, and have a function of releasing heat to both sides of the upper case 21.

[0061] Further, the front heat sinks 21-2 are formed on the front surface of the upper case 21. That is, a groove frame 21-3 is formed on the front surface of the upper case 21 in the height direction of the upper case 21, and the front heat sinks 21-2 are formed by penetrating the space between the groove frames 21-3.
