According to the present disclosure, it is possible to smoothly lift and lower a top-down portable direct-fired cooker and to stably maintain a state after the lifting and lowering operations.

TECHNICAL FIELD

The present disclosure relates to a portable direct-fired cooker that is portable and easily bakes and heats a roasted material indoors and outdoors.

BACKGROUND ART

In general, cookers are devices for cooking a roasted material with heat, and are classified into a direct heating type using a flame of gas and charcoal and an indirect heating type using electricity according to a method of providing heat.

For example, in the case of a direct-fired cooker using charcoal among the direct heating types, it may be difficult to control a size of a flame, so the inside of a roasted material is not cooked properly while only the outside is burned and ash and soot scatter during combustion, and thus, as a solution, a direct-fired cooker using butane gas has been proposed.

That is, the direct-fired cooker using butane gas has the advantage of easy flame control, but in most cookers, flames are generated below a roasting plate on which meat is put, so that smoke or toxic gas occurs when juice or oil generated by the roasted material falls, and during roasting, the roasted material may be easily pressed to a roasting plate, which causes burning of the roasted material.

In order to solve the problems, a top-down type cooker in which a flame is generated from the top has been proposed, including the ‘Portable direct-fired cooker’ of Korean Patent Laid-Open No. 10-2012-0083169 (published on Jul. 25, 2012), the ‘Table-mounted and portable direct-fired cooker and warmer’ of Korean Patent Registration No. 10-1454356 (published on Oct. 23, 2014), the ‘Two-way cooker with a roasting table elevating structure’ of Korean Patent Laid-Open No. 10-2014-0146882 (published on Dec. 29, 2014) and Registration No. 10-1715572 (published on Mar. 22, 2017), etc.

These top-down cookers resolve the problems in which juice or oil generated by a roasted material falls to cause smoke and toxic gas and the roasted material is easily pressed to a roasting plate during roasting, and in order to resolve a problem of a long roasting time, which is a problem of the top-down roasters, a lift is installed so that a height of the roasting plate may be adjusted, but since the roasting plate is lifted and lowered in a state in which a weight of the roasted material is added to the roasting plate, lifting and lowering of the roasting plate may not be smooth.

In addition, since the roasting plate is lifted and lowered by the lift, it may be difficult to maintain the lifted roasting plate by its own weight in the lifted state or it may be unstable to maintain the lowered roasting plate in the lowered state due to a repulsive force, and in such a case, a high risk may occur.

FIGS.1and2show a coupled and separated state of a portable direct-fired cooker of the present disclosure, andFIG.3is a partial view of a portable direct-fired cooker of the present disclosure.

Hereinafter, a portable direct-fired cooker according to an embodiment of the present disclosure will be described with reference toFIGS.1to3.

A portable direct-fired cooker of the present disclosure includes a gas supply unit1accommodating a butane gas container in an accommodation chamber formed at an upper portion of a rear end of a lower case31and discharging a butane gas through an adjustment valve12, a flame unit2including a heater module downwardly emitting a flame heat generated by discharging and burning a butane gas that is discharged through the gas supply unit1to a lower side of the upper case21toward a lower case31of a roasting unit3, a thermal insulation container23introduced to an open portion by opening the upper case21and mounted at an upper end of the heater module to heat a roasted material with naturally rising heat emitted by the heater module, a roasting plate32bisected into left and right plates321and321′, which include a plurality of ribs322protruding to discharge oil on an upper roasting surface to provide an oil drop space between protruding pieces322′ of the rib322portion in which the left and right plates321and321′ are in contact with each other so that the protruding piece322′ and a first fixing protrusion protruding from an upper end of a side surface of the left and right plates321and321′ are inserted into and coupled to a guide groove formed at both ends of an upper side of the lower case31and a first fixing hole13formed at an upper side of the gas supply unit1to serve as a horizontal cover, a lid4covering the thermal insulation container23, and a handle5formed on the lid4.

Also, the roasting plate32is fitted and coupled to the lifting frame33, and the lifting frame33is lifted and lowered by the lift unit35to bring the roasted material closer to or separated from the heater module.

The lift unit35is fixed to the lower case31by support brackets351and351′ and includes a first link352and a second link352′ having one end mounted on a vertical surface at both sides of the support brackets351and351′ to be axially fixed and moved, and coupled to each other by a hinge shaft in the center, and the other end of the first link352and the second link352′ is axially fixed to and move on a vertical surface of the lifting frame33.

Furthermore, in the present disclosure, an elastic spring353is mounted on the inner bottom surface of the lower case31so that the lifting frame33may be smoothly lifted and lowered by the lift unit35.

The elastic spring353is preferably mounted on the lower case31at a point corresponding to an intersection of the first link352and the second link352′.

Also, in order to prevent contamination by foreign substances caught in the elastic spring353, a spring cover354protecting the elastic spring353is fitted and coupled to the elastic spring353.

When the lifting frame33is lifted, the lifting frame33is supported by the lifting guider40.

The lifting guider40is coupled to front surfaces of the upper case21and the lower case31, and a guide groove411is formed in a vertical direction.

Also, a skewer holder recess412is formed at a middle portion to also serve as a skewer holder.

The lifting frame33is supported and fixed by the coupling unit50and a lifting fixing lever60.

The coupling unit50passes through a front surface of the lifting frame33to be coupled with the lifting fixing lever60, and a rotating coupling portion611protruding in a horizontal direction from an upper portion of the lifting fixing lever60is hinged to the coupling unit50through the guide groove411of the lifting guider40

Accordingly, the lifting frame33is stably lifted and lowered within the range of the guide groove411of the lifting guider40.

Furthermore, in the present disclosure, it is configured to maintain a maximally lifted or a maximally lowered state when the lifting frame33is lifted and lowered, and first,FIG.5shows a state in which the lifting frame33is lowered, and in the present disclosure, the lowered lifting frame33is prevented from being unintentionally lifted.

Referring toFIG.6together, the lifting fixing lever60has a fixing protrusion612protruding from a lower portion in a horizontal direction. Here, the lower portion of the lifting fixing lever60is more preferably wider than an upper portion to serve as a handle.

In addition, a protrusion324-2is formed on a front surface of the oil tray324accommodated in the lower case31, and a lowering fixing groove324-1is formed in the rim of the protrusion324-2.

A lower side of the protrusion324-2is preferably in the shape of a perforated square rim, so that the fixing protrusion612of the lifting fixing lever60in a lowered state is inserted into the lowering fixing groove324-1and the lifting fixing lever60is prevented from being operated in an upward direction.

Next, in order to lift the lifting frame33, when a lower portion of the lifting fixing lever60is gripped and pulled, the lifting fixing lever60is rotated based on the rotating coupling portion611and restraining of the fixing protrusion612by the lowering fixing groove324-1is released.

Accordingly, the lifting frame33is in a state of being lifted by the lift unit35.

FIG.7shows a state in which the lifting frame33is lifted. Referring toFIG.8, the fixing protrusion612of the lifting fixing lever60lifted together with the lifting frame33is inserted into the guide groove411of the lifting guider40, so that the lifting fixing lever60is prevented from being operated in a downward direction.

Meanwhile, the fixing protrusion612of the lifting fixing lever60is configured to increase in height toward an end, so that the fixing protrusion612may not be easily separated from a state in which the fixing protrusion612is inserted into the guide groove411or the lowering fixing groove612, and in addition, in order to prevent excessive operation in the insertion direction, a stopper612-1shorter than a protruding length of the fixing protrusion612may be formed to protrude from the side of the fixing protrusion612.

As described above, the portable direct-fired cooker of the present disclosure may improve the safety of the cooker by allowing the roasting plate to be smoothly lifted and lowered and stably maintaining the lifted and lowered state.
