(12) The ignition device 300 using the pellet fuel 800 according to the present invention includes the container part 310, a heater bar 320, and a cover 330.

(13) According to the present embodiment, the container part 310 includes an outer container 311 to which air is supplied from the air blowing part 500, and an inner container 312 provided inside the outer container 311 and in which the pellet fuel 800 supplied thereto from the pellet supply part 400 is ignited.

(14) The container part 310 includes an air circulation space 311a formed therein, i.e., between the outer container 311 and the inner container 312.

(15) A blowhole 311b configured to allow introduction of outside air by the air blowing part 500 and circulate the air inside the housing 100 to allow the air to be supplied to the air circulation space 311a is formed at a side surface of the outer container 311.

(16) Here, the blowhole 311b is formed to communicate with the air blowing part 500 to facilitate the supply of the outside air into the air circulation space 311a by the air blowing part 500.

(17) A heater bar insertion part 311c is formed at a rear surface of the outer container 311 to allow the heater bar 320 to be inserted into the air circulation space 311a.

(18) The inner container 312 is provided inside the outer container 311, has an upper end part integrally provided with an upper part of the outer container 311, and has a plurality of through-holes 312a formed therein at predetermined intervals to allow outside air introduced into an outer peripheral surface and a lower end surface of the inner container 312 by the air blowing part 500 to be circulated to facilitate ignition of the pellet fuel 800.

(19) That is, the container part 310 is provided in the combustion chamber 200, and the blowhole 311b is formed to communicate with the air blowing part 500 so that outside air is introduced into the air circulation space 311a via the blowhole 311b due to an operation of the air blowing part 500 and is circulated via the through-holes 312a, and ignition of the pellet fuel 800 accommodated in the inner container 312 is facilitated.

(20) A heat supply part 312b configured to supply a heat source into the inner container 312 is formed at the inner bottom of the inner container 312 to ignite the pellet fuel 800.

(21) Supports 313 are provided at an upper part of the bottom of the inner container 312, i.e., an upper part of the heat supply part 312b, such that the plurality of supports 313 are provided at upper parts at both sides of heat supply part 312b.

(22) An inner part of the inner container 312 is provided to be wide at a top end and gradually narrow toward the bottom to allow flames to widely spread as the pellet fuel 800 burns and allow food such as meat to be evenly cooked.

(23) The heater bar 320 heated by electrical energy and configured to ignite the pellet fuel 800 is provided at a lower part of the inner container 312.

(24) The heater bar 320 may be provided in the heat supply part 312b of the inner container 312 via the heater bar insertion part 311c to be electrically connected thereto and ignite the pellet fuel 800 accommodated in the inner container 312.

(25) The heater bar 320 is provided in a stick shape so that the heat source is evenly transmitted to both sides of the inner container 312 and heat supply efficiency is enhanced.

(26) That is, as the heater bar 320 is formed in the stick shape, a high heat source of the heater bar 320 is rapidly transmitted to the pellet fuel 800 that is supplied to both sides of the inner container 312, and the pellet fuel 800 is able to be ignited as quickly as possible.

(27) The cover 330 is provided at the inner bottom of the inner container 312 to cover the heater bar 320.

(28) The cover 330 is provided at the upper part of the heat supply part 312b and seated on the supports 313.

(29) A seating part 331 is formed at an inner surface of the cover 330 to prevent movement of the cover 330 when the cover 330 is seated on the supports 313.

(30) The cover 330 has both side surfaces provided at the plurality of supports 313 that are provided at the bottom of the inner container 312 so that the cover 330 may remain horizontal at the bottom of the inner container 312.

(31) The cover 330 may be provided at the supports 313 such that the bottom of the inner container 312 and the lower surface of the cover 330 are spaced apart from each other, and a space portion 332 is formed therebetween.

(32) That is, a height of the cover 330 is shorter than a height of the support 313 so that the space portion 332 is formed between the inner container 312 and the cover 330.

(33) The space portion 332 is formed at both sides of the cover 330.

(34) Operation states of the ignition device using pellet fuel according to the present invention configured as above will be described below.

(35) The ignition device 300 is provided in the combustion chamber 200 of the housing 100, and the pellet fuel 800 that is supplied into the inner container 312 of the container part 310 via the pellet supply part 400 is ignited by the ignition device 300 and burns.

(36) Here, the pellet fuel 800 accommodated in the pellet supply part 400 is supplied into the inner container 312, heat is transmitted to the pellet fuel 800 accommodated in the inner container 312 as the heater bar 312 is heated by power supplied thereto, and the pellet fuel 800 is ignited.

(37) When the pellet fuel 800 is ignited due to the heating of the heater bar 320, air generated in the air blowing part 500 is supplied into the air circulation space 311a via the blowhole 311b, and the pellet fuel 800 is ignited within the shortest possible time due to the heat source transmitted to the cover 330.

(38) When the cover 330 is provided at the supports 313, the heat supply part 312b and the space portion 332 communicate because the space portion 332 is formed between the inner container 312 and the cover 330, and the heat source generated in the heater bar 320 is smoothly transmitted to the pellet fuel 800.

(39) When the pellet fuel 800 drops from the pellet supply part 400 to the inner container 312, the cover 330 prevents the pellet fuel 800 from dropping below the inner container 312 via the heat supply part 312b of the inner container 312 and allows the pellet fuel 800 to be accommodated in the inner container 312.

(40) Therefore, in the present invention, the heat supply part 312b is formed at the bottom of the inner container 312, the heater bar 320 in the stick shape is provided at the heat supply part 312b, the cover 330 is provided at the supports 313 of the inner container 312, and the space portion 332 is formed between the cover 330 and the bottom of the inner container 312 when the cover 330 covers the heater bar 320 and the heat supply part 312b, thereby allowing the pellet fuel 800 accommodated in the inner container 312 to be ignited and burn within a short time due to the heat source caused by the heater bar 320, the cover 330, and the space portion 332.

(41) The present invention is not limited to the particular exemplary embodiment described above, and one of ordinary skill in the art to which the invention pertains should be able to modify and practice the present invention in various other ways without departing from the gist of the present invention, with such modifications belonging to the scope of the claims below.
