Description

Technical Field

[0001] This invention relates to a portable direct-fire barbecue grill, which, being portable, allows for easy grilling and heating of food both indoors and outdoors. Background Technology

[0002] Generally, barbecue grills, as devices that use heat to cook food, are classified into two types based on the method of providing heat: direct heating using gas or charcoal flames and indirect heating using electricity.

[0003] For example, in direct heating methods, direct-fire grills using charcoal have the following problems due to the difficulty in adjusting the size of the flame: the inside of the food is not fully cooked and only the surface is charred, and ash and smoke are produced during combustion. As a solution to these problems, direct-fire grills using butane gas have been proposed.

[0004] In other words, direct-fire grills that use butane gas for direct heating have the advantage of easy flame adjustment. However, in most grills, the flame is located below the grill pan used to place the meat above the flame. Therefore, there are problems such as smoke and toxic gases generated by dripping meat juices or oil from the grilled food, and the food easily sticking to the grill pan during grilling, causing the food to burn.

[0005] To address these issues, downward-facing barbecue grills that generate flames from the top have been proposed, including Korean Patent No. 10-2012-0083169 (published on July 25, 2012) "Portable Direct-Flame Barbecue Grill," and Patent No. 10-1454356 (announced on October 23, 2014) "A Portable Heater and Direct-Flame Barbecue Grill with Table Mounting," as well as Korean Patent No. 10-2014-0146882 (published on December 29, 2014) and Patent No. 10-1715572 (announced on March 22, 2017) "A Two-Way Barbecue Grill with a Lifting and Lowering Structure," etc.

[0006] Downward-facing grills like this can improve the problem of smoke and toxic gases caused by dripping meat juices or oil from the grilled food, and also improve the problem of food sticking to the grill plate during grilling. However, in order to improve the problem of long grilling time that is a problem with downward-facing grills, a lifting mechanism is installed to adjust the height of the grill plate. However, when raising and lowering the grill plate with the weight of the food on it, the lifting and lowering becomes uneven.

[0007] Furthermore, since the lifting and lowering are carried out by means of an elevator, the following situations may occur: when rising, it is difficult to maintain the upward state due to its own weight, or when falling, the rebound force makes the downward state unstable, which may also cause great danger.

[0008] The background information described above is intended to help understand the background of the invention and may include matters that are not known prior art to a person skilled in the art.

[0059] In order to fully understand the present invention and its operational advantages and the objectives achieved by implementing the present invention, it is necessary to refer to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the drawings.

[0060] In describing the preferred embodiments of the present invention, descriptions of well-known techniques or repetitive descriptions that may unnecessarily obscure the essence of the invention will be reduced or omitted.

[0061] Figure 1 and Figure 2 The diagram illustrates the combined and disassembled states of the portable direct-fire barbecue grill according to the present invention. Figure 3 This is a partial schematic diagram of a portable direct-fire barbecue grill according to the present invention.

[0062] Below, refer to Figures 1 to 3 A portable direct-fire barbecue grill according to an embodiment of the present invention will be described.

[0063] The portable direct-fire grill of the present invention includes: a gas supply unit 1, wherein the gas supply unit 1 accommodates a butane gas container in a receiving chamber formed on the upper rear end of the lower shell 31, thereby discharging butane gas through a regulating valve 12; a flame unit 2, wherein the flame unit 2 has a heating module, wherein the heating module radiates the hot air of the flame downward toward the lower shell 31 of the grilling unit 3, the flame being generated by burning the butane gas discharged through the gas supply unit 1 and directed toward the lower side of the upper shell 21; and a heat preservation container 23, wherein the heat preservation container 23 opens the upper shell 21, and is installed on the upper end of the heating module through the open portion, so that the grilling food can be heated by the hot air released by the natural rising of the heating module. The barbecue pan 32 is divided into two equal parts, namely left and right side pans 321 and 321'. To drain oil, multiple protruding ribs 322 are formed on the upper barbecue surface. An oil drip space is provided between the protruding pieces 322' of the ribs 322 where the left and right side pans 321 and 321' meet. The protruding pieces 322' and the first fixing protrusions protruding from the upper side of the left and right side pans 321 and 321' are inserted into the guide grooves formed at both ends of the upper side of the lower shell 31 and the first fixing hole 13 formed on the upper side of the gas supply part 1, thereby covering the left and right sides. The lid 4 covers the heat preservation container 23 and the handle 5, which is formed on the lid 4.

[0064] Furthermore, the barbecue plate 32 is inserted into the lifting frame 33, which is raised and lowered by means of the lifting part 35, so that the barbecue food is close to or spaced from the heating module.

[0065] The lifting part 35 is fixed to the lower shell 31 by means of support brackets 351 and 351', and is composed of a first link 352 and a second link 352'. As for the first link 352 and the second link 352', one end is installed on the vertical surfaces on both sides of the support brackets 351 and 351' for shaft fixation and movement, and they are connected to each other in the center by means of a hinge shaft. The other end of the first link 352 and the second link 352' is formed on the vertical surface of the lifting frame 33 for shaft fixation and movement.

[0066] Furthermore, the present invention installs an elastic spring 353 on the bottom surface inside the lower shell 31, so that the lifting frame 33 can be lifted and lowered smoothly by means of the lifting part 35.

[0067] It is preferable that the elastic spring 353 is installed in the lower housing 31 at the intersection of the first link 352 and the second link 352'.

[0068] Furthermore, to prevent impurities from getting trapped in the elastic spring 353 and causing contamination, a spring cover 354 protecting the elastic spring 353 is inserted and attached to the elastic spring 353.

[0069] When the lifting frame 33 is raised or lowered, it is supported by the lifting guide 40.

[0070] The lifting guide 40 is attached to the front surface of the upper shell 21 and the lower shell 31, forming a guide groove 411 in the vertical direction.

[0071] Furthermore, the middle part forms a skewer placement groove 412, which also serves as a skewer support.

[0072] The support and fixation of the lifting frame 33 are formed by the combination unit 50 and the lifting fixing rod 60.

[0073] The connecting unit 50 passes through the front surface of the lifting frame 33 and is connected to the lifting fixing rod 60. The rotating connecting part 611, which protrudes horizontally from the upper part of the lifting fixing rod 60, passes through the guide groove 411 of the lifting guide 40 and is hinged to the connecting unit 50.

[0074] Therefore, the lifting frame 33 can rise and fall stably within the guide groove 411 of the lifting guide 40.

[0075] Furthermore, a feature of the present invention is that, when the lifting frame 33 is raised or lowered, it can maintain the maximum upward or maximum downward state. Figure 5 With the lifting frame 33 in a lowered state, the present invention can prevent the lowered lifting frame 33 from rising erratically.

[0076] Refer to together Figure 6 The lifting and fixing rod 60 has a horizontally protruding fixing protrusion 612 at its lower part. More preferably, the lower part of the lifting and fixing rod 60 is wider than the upper part, so as to function as a handle.

[0077] Furthermore, a protrusion 324-2 is formed in the front surface of the oil receiving member 324 housed in the lower shell 31, and a descending fixing groove 324-1 is formed in the frame of the protrusion 324-2.

[0078] Preferably, the lower side of the protrusion 324-2 is a four-corner frame shape that has been opened. Therefore, in the lowered state, the fixing protrusion 612 of the lifting fixing rod 60 is inserted into the lowering fixing groove 324-1, so that the lifting fixing rod 60 cannot move upward.

[0079] Then, in order to raise the lifting frame 33, when the lifting fixing rod 60 is held and pulled, the lifting fixing rod 60 rotates with the rotating joint 611 as a reference, thereby releasing the constraint of the lowering fixing groove 324-1 by means of the fixing protrusion 612.

[0080] Accordingly, with the help of the lifting part 35, the lifting frame 33 becomes a state that can be raised.

[0081] Figure 7 As the lifting frame 33 is in the raised state, when it is in contact with... Figure 8 When referring to the same, the fixed protrusion 612 of the lifting fixed rod 60, which rises together with the lifting frame 33, is inserted into the guide groove 411 of the lifting guide 40, so that the lifting fixed rod 60 cannot move downward.

[0082] In addition, the height of the fixed protrusion 612 of the lifting fixing rod 60 increases towards the end, making it difficult to detach when inserted into the guide groove 411 or the lowering fixing groove 324-1. Furthermore, in order to prevent excessive rotation in the insertion direction, a stop member 612-1 that is shorter than the protrusion length of the fixed protrusion 612 can be formed on the side of the fixed protrusion 612.

[0083] As observed above, the portable direct-fire grill of the present invention allows for smooth lifting and lowering of the grill pan, and also maintains a stable lifting and lowering state, thus improving the safety of the grill.

[0084] Although the invention has been described above with reference to the illustrated figures, it is not limited to the described embodiments. Various modifications and variations can be made without departing from the spirit and scope of the invention, which will be self-evident to those skilled in the art. Therefore, such modifications or variations should be included within the scope of patent protection of this invention, and the scope of the invention should be interpreted based on the appended patent claims.
