As described above, the intake air transmission unit 42 is formed to correspond to the length of the burner 3 , and a plurality of intake discharge units 43 are provided at intervals along the longitudinal direction at the upper portion of the intake transmission unit 42 . , there is an advantage that the air supplied by the blower AB can be more effectively and efficiently supplied to the burner 3 and the charcoal barrel 1 .

Meanwhile, referring to FIGS. 1 to 5 , the main body 2 may include an opening 23 formed by the upper end of the side wall plate WP as described above. In addition, the main body 2 has a cover part 24 for opening and closing the opening 23 , and an inlet 251 communicates with the upper side of the receiving part 21 , and the space between the inner wall IW and the outer wall OW of the main body 2 . may include an exhaust duct unit 25 formed by , and an exhaust outlet unit 26 communicating with the outlet 252 of the exhaust duct 25 to discharge the air of the exhaust duct unit 25 to the outside.

That is, in the process of igniting the charcoal accommodated in the accommodating part 21 of the device, the opening 23 is closed through the cover part 24, and the air supplied from the intake pipe 4 and the char are ignited. The generated smoke enters the exhaust duct part 25 through the inlet 251 of the exhaust duct part 25 provided above the charcoal barrel 1 in the accommodating part 21 (entry into the exhaust duct part 25) The oil contained in the smoke or the like before may fall to the drip tray 5 side described above).

Based on the movement direction of the air containing smoke in the exhaust duct unit 25 , the air may move from the front end of the exhaust duct unit 25 to the outlet 252 side of the exhaust duct unit 25 provided at the rear end. At this time, the outlet 252 of the exhaust duct unit 25 may be provided at the lower side of the device.

In this case, for example, a filter box 27 may be provided between the exhaust duct unit 25 and the exhaust outlet unit 26 , and the filter box 27 includes impurities, etc. from the air moving in the exhaust duct unit 25 . A filter that removes the The filter box 27 is preferably formed in a structure that can be opened and closed to enable replacement and maintenance of the filter.

Air discharged from the outlet 252 of the exhaust duct 25 may communicate with the exhaust outlet 26 to be discharged to the outside of the device.

That is, the air containing smoke generated in the process of igniting charcoal or in the process of grilling meat closes the opening 23 through the cover part 24, and the air in the accommodation part 21 is exhausted from the exhaust duct part 25 ), there is an advantage that it can be guided outside the room where the device is installed.

A grill on which meat, etc. is seated may be seated on the upper side of the charcoal barrel 1, and the cover part 24 is lifted to open the opening 23 in the process of introducing, withdrawing, and turning over in the process of replacing charcoal or grilling air. can be opened

On the other hand, referring to FIGS. 1 to 7 , the charcoal barrel 1 extends downward from the lower portion of the seating part 13 , and a pair of detachable coupling parts 11 facing at intervals along the longitudinal direction of the charcoal barrel 1 . ), and a pair of detachable and coupled parts 11 respectively and a pair of detachable corresponding parts 121 and a pair of detachable corresponding parts 121 that are respectively detachably coupled to each other and extend inward along the horizontal direction in each of the pair A flame dispersing part 12 including a blocking part 122 that interconnects the detachable parts 121 of the mounting part 13 and has a length corresponding to the length of the seating part 13 and has a width smaller than the width of the seating part 13 ) may be included.

Illustratively, the detachable coupling part 11 may include a plate 112 extending downward from the lower portion of the seating part 13 and a concave groove 111 through which one surface and the other surface of the plate 112 are penetrated. can The concave groove 111 may include an upper groove 111a having a first width and a lower groove 111b provided in the lower portion of the upper groove 111a and having a width smaller than the first width, and the detachable corresponding part ( 121) has a width corresponding to the second width and can be mounted by being inserted into the lower groove 111b. At this time, the blocking part 122 is formed to be larger than the second width, and the blocking part 122 is caught on the plate 112 in a state in which the detachable corresponding part 121 is inserted into the lower groove 111b, so that the flame dispersing part ( 12) is restricted from moving in the longitudinal direction, so that the flame dispersing unit 12 may be coupled to the detachable coupling unit 11 .

At this time, when the flame dispersing part 12 moves upward, the detachable part 121 may be moved in the width direction in the upper groove 111a, and the detachable part 121 passes through the concave groove 111 . It can be withdrawn so as not to be, and it is possible to release the coupling between the flame dispersing part 12 and the detachable coupling part 11 .

As described above, the charcoal barrel (1) is said to be disposed above the burner (3), likewise the flame dispersing part (12) is also disposed above the burner (3), and the detachable coupling part (11) is lower than the seating part (13). Since it is provided in the flame dispersing part 12 is disposed below the seating part (13).

As the flame discharge hole 31 in the burner 3 is larger, the intensity of the flame is weakened, and it does not sufficiently reach at least one of both ends in the pipe. Even using the burner 3, it is possible to adjust the width on the movement path of the flame through the detachable coupling part 11 and the detachably coupled flame spreading part 12, so that the intensity of the flame and the height of the flame can be adjusted. there is.

In particular, in using the burner 3 having a fixed size of the flame discharge hole 31, when using a large width of the seating portion 13, the flame is dispersed along the width direction by combining the flame dispersing portion 12. Therefore, it is possible to improve the ignition efficiency of charcoal. Therefore, it may be preferable that both sides of the flame spreader 12 are inclined upward to improve the outer side with respect to the longitudinal direction.

Meanwhile, referring to FIGS. 1 to 7 , the main body 2 protrudes upward from the lower side (bottom plate BP) of the receiving part 21 to the burner 3 , and on both sides with respect to the intake air transmission part 42 . It may include a pair of guide portions 22 provided, respectively.

Exemplarily, the guide portion 22 may extend from the bottom plate BP to the lower portion of the burner 3 .

It is preferable that the guide part 22 extends along the longitudinal direction of the intake pipe 4 .

As described above, since the present device includes the guide part 22, the air supplied by the intake pipe 4 can be delivered to the burner 3 and the charcoal barrel 1 without being dispersed, thereby improving the ignition efficiency of charcoal. There are advantages to being able to do it.

Referring to FIG. 7 , as described above, the bottom plate BP may include a horizontal portion BP1 and an inclined portion BP2 inclined upwardly to the outside, and the guide portion 22 is disposed on the horizontal portion BP1. The horizontal part 221 to be seated on, the inclined part 222 inclined upwardly outwardly so as to be seated on the inclined portion BP2 at the outer end of the horizontal part 221, and the horizontal part 221 extending upward from the inner end of the horizontal part 221 It may include a vertical part 223 .

The air supplied from the intake pipe 4 may be supplied to the burner 3 and the charcoal barrel 1 by being guided by the vertical part 223 .

In the guide part 22 , the vertical part 223 is restricted from moving inward by the intake pipe 4 , and the inclined part 222 is restricted from moving outward by the inclined part BP2 to move outward. can be limited.

That is, movement of the guide part 22 along the width direction by the vertical part 223 and the inclined part 222 may be restricted.

As described above, the lower end of the drip tray 5 is said to be spaced apart from the lower side (bottom plate BP) of the receiving portion 21 . At this time, the oil contained in the smoke in the accommodating part 21 may fall to the bottom plate BP side of the accommodating part 21 through the seating part 13 and the through hole 54, and the falling oil is the guide part. It can be loaded onto the horizontal part 221 of the 22, and the guide part 22 is moved in the vertical direction to remove it from the receiving part 21 of the main body 2 and then washed to remove oil, etc. there is.

On the other hand, the main body 2 is made of a metal material because rigidity is required because the charcoal barrel 1 is seated on the inside, and a grill on which meat containing moisture, oil, etc. is seated can be disposed on the upper side of the charcoal barrel 1 . can be formed.

At the same time, the main body 2 may be exposed to a harsh environment due to its nature, and there is a risk of corrosion because it is always exposed to moisture, such as installed on the dining table where water for roasting meat is placed, and washing with a dishcloth, etc., Charcoal barrel 1 is repeatedly drawn out and drawn in from the receiving part 21, and there is a possibility that scratches may occur due to movement of scissors, tongs, and the like.

In addition, since the charcoal barrel 1 on which the charcoal is seated inside the accommodating part 21 and the grill on which the meat containing water and oil are seated on the upper side of the charcoal barrel 1 can be accommodated, damage, deformation, etc. may occur due to the load. There are also concerns.

In the case of scratches, the corrosion rate can be improved because crack corrosion can occur in the part where the scratches are formed, and when a load is repeatedly applied to the main body 2 while corrosion is in progress, stress corrosion cracking occurs and the crack rate is improved. can

If scratches and corrosion occur on the outer surface of the main body 2, it is of course not aesthetically pleasing and unsanitary.

Referring to Figure 8, the body 2 may include a coating film (G) provided on the outer surface as a means for solving the above problem. The coating film (G) is in contact with the outer surface of the main body (2), but is softened in a first temperature range (G1), the heating layer (G2) provided on the adhesive layer (G1), the heating layer (G2) on the upper A protective layer (G4) provided on the intermediate layer (G3) that is provided and softened in a second temperature range higher than the first temperature range and the intermediate layer (G3), but softened at a third temperature higher than the second temperature range (G4) may include.

By including the protective layer (G4), the coating film (G) has a high surface hardness and excellent abrasion resistance, thereby suppressing the occurrence of scratches and the like on the body (2), and has water repellency to prevent corrosion of the body (2) can be suppressed In particular, the coating film (G) includes an adhesive layer (G1) and an intermediate layer (G3) that are softened in the first temperature range and the second temperature range, which are lower temperatures, respectively, unlike the protective layer (G4) of the surface, the coating film (G) surface While maintaining the physical and chemical properties of the protective layer (G4) provided on the surface, it is possible to more effectively remove the residual stress of the coating film (G) according to the external environment such as thermal expansion and bending, thereby suppressing breakage such as peeling, thereby prolonging the service life. Because it can be extended, it is possible to protect the body 2 from the external environment for a longer period of time.

In a specific embodiment, the adhesive layer G1 may include polybutylacrylate (PBA) and polymethyl methacrylate (PMMA). When the thickness of the adhesive layer (G1) is thick, a temperature gradient occurs between the portion in contact with the outer surface of the heating layer (G2) and the body (2), which will be described later, and softening of the portion in contact with the outer surface of the body (2) in the adhesive layer (G1) It is preferable that the thickness is 0.020mm to 0.150mm because it may not be made smoothly.

Exemplarily, the adhesive layer G1 may be a thermal impregnation of polybutyl acrylate and polymethyl methacrylate. The softening temperature of the adhesive layer G1 is 90° C. to 100° C., which corresponds to the above-described first temperature range.

In this way, in the coating film (G), the adhesive layer (G1) is softened in the first temperature range, which is the lowest temperature, so that the outer surface of the main body (2) and the adhesive force are excellent, so that peeling is suppressed.

The heating layer G2 is provided on the adhesive layer G1 and includes polyacetylene and iodine. Polyacetylene does not have a gap through which electrons flow in a conjugated double bond state, but since the gap can be widened by mixing different small molecules like iodine, electrons flow and when electricity is applied, heat is generated due to electrical resistance.

In this way, by including the heating layer (G2), it is not necessary to apply a large voltage to soften the above-described adhesive layer (G1) and the intermediate layer (G3) to be described later, more economically extending the service life of the coating film (G) There are advantages to being able to do it.

The intermediate layer (G3) may include 100 parts by weight of the cellulose acetate butyrate and 200 parts by weight of the carboxylate acrylic copolymer. If the weight ratio is out of the above-described weight ratio, the adhesive force between the adhesive layer G1 and the protective layer G4 may become insufficient, and thus a problem in that the film peels off during use may occur. The softening temperature of the intermediate layer G3 is 150° C. to 160° C., which corresponds to the second temperature range.

The protective layer (G4) may include 50 parts by weight of polymethylphenylsiloxane in toluene, 50 parts by weight of silicon-containing fiber, 50 parts by weight of silicon carbide, 6 parts by weight of manganese oxide, and 18 parts by weight of organosilicon-titanium compound. there is.

When the amount of polymethylphenylsiloic acid is less than 50 parts by weight, the softening temperature is reduced, the difference from the second temperature range is small and the hardness is reduced, and when it exceeds 50 parts by weight, it is not economical. When the silicone-containing fiber is less than 50 parts by weight, the water repellency is poor, and when it exceeds 50 parts by weight, the water repellency does not tend to be improved, so it is not economical. If the amount of silicon carbide is less than 50 parts by weight, the abrasion resistance is reduced, and when it exceeds 50 parts by weight, the abrasion resistance does not tend to be improved, so it is not economical. When the amount of the organosilicon-titanium compound is less than 18 parts by weight, the surface hardness and abrasion resistance are reduced, and when it exceeds 18 parts by weight, the degree of hardening is not clear, so it is not economical.

As such, the softening temperature of the protective layer G4 is 650° C. (the third temperature), which maintains hardness even at a temperature lower than the third temperature, which is a temperature higher than the second temperature range, to maintain abrasion resistance and maintain water repellency. The main body 2 can be effectively protected from the external environment.

As described above, the coating film (G) is provided on the outer surface of the main body (2), and residual stress such as compressive stress and tensile stress may be generated due to the difference in the coefficient of thermal expansion with the main body (2), bending due to shape and external force, etc. And, when such residual stress is generated, the coating film (G) may have microincontinence called crazing, cracks, hillocks, wrinkles (wrinkling), breakage, and the like.

Therefore, by applying electricity to the heating layer (G2) so that the adhesive layer (G1) and the intermediate layer (G3) reach the first temperature range and the second temperature range, respectively, the residual stress in the adhesive layer (G1) and the intermediate layer (G3) is removed, respectively This is to suppress the occurrence of fracture due to residual stress.

At this time, it is important that the heating layer (G2) is heated below the third temperature so that the protective layer (G4) is not softened, and thus the adhesive layer (G1) and the intermediate layer (G3) reach the first temperature range and the second temperature range, respectively. During the softening process, the protective layer G4 is not softened, and thus excellent hardness, abrasion resistance, water repellency, and the like may be maintained.

In particular, when the heating layer (G2) is heated to a temperature adjacent to the first temperature range (eg 150 ℃) in the second temperature range, the degree of softening of the intermediate layer (G3) is less than that of the adhesive layer (G1), so that the intermediate layer (G3) Since it serves as a buffer between the adhesive layer G1 and the protective layer G4, it can serve as a bridge between the adhesive layer G1 and the protective layer G4.

That is, since the residual stress of the coating film G can be effectively dispersed and relaxed while maintaining the physical and chemical properties of the protective layer G4, the body 2 can be continuously protected from external environments such as scratches and corrosion. There is an advantage that
