Referring to (a) of FIG. 7, heat generated in the burner part 304 of the conventional portable cooking apparatus is transferred to the fire plate 400 on which the three feet are placed, and cooking is performed, at this time, the peripheral direction of the burner part 304 As a closed wall does not exist, heat is easily leaked to the outside, and the flame of the burner part may be extinguished or the flame may be weakened by the outside wind. On the other hand, referring to (b) of FIG. 7, in the portable cooking apparatus of the present invention, the burner plate 115 is placed on the upper part of the burner portion, and the periphery of the burner portion is blocked by the plate stand 114, and between the plate and the plate stand. Since heat can only flow out through the intentionally formed gap, it is possible to minimize the outflow of heat required for cooking, and the cooking efficiency is improved because the burner buoy flame is less affected by external wind.

8 is a view for comparing and explaining the fuel cell heating method in the conventional portable cooking device and the portable cooking device of the present invention. Referring to (a) of FIG. 8, in the conventional portable cooking apparatus, the heat of the burner portion is transferred to the plate and the re-radiated heat is transferred to the fuel container storage space to heat the fuel tank. This heat transfer is intended to induce stable vaporization of butane gas by lowering the temperature of the cooled fuel tank during the vaporization process. On the other hand, referring to Figure 8 (B), in the portable cooking apparatus of the present invention, heat generated in the burner portion can be effectively transferred to a lower housing direction with a relatively close distance. The heat of the burner part is primarily transferred to the fire plate, and the heat re-radiated from the fire plate is transferred to the fuel tank through radiation or convection back to the heat shield plate and the lower housing. At this time, if too much heat is transferred to the fuel tank, the fuel tank may overheat, and thus, holes of appropriate sizes are formed in the heat shield plate and the lower housing. The holes formed in the heat shield and the lower housing also function to supply air necessary for combustion in the burner. In addition, the conventional portable cooking device has a single-layered gas container block (fuel mounting part cover), which may cause an explosion due to an increase in the temperature of the gas container when using an overboard plate, but the gas roaster filed by us prevents gas container explosion. To this end, it has a double structure of a heat shield plate and an upper housing, so it can be expected to have an effect of blocking heat.

9 is a view for comparing and explaining the stability of the locking device of the fuel tank cover in the conventional portable cooking device and the portable cooking device of the present invention. Referring to (a) of FIG. 9, in the conventional portable cooking apparatus, the locking formed by engaging the projection formed at the position corresponding to the projection formed on the fuel mounting cover, the locking of this method can be easily released by force or impact on the outside. It is a structure. Therefore, in the process of moving and manipulating the portable cooking apparatus, discomfort of the locking device may be released. On the other hand, referring to (B) of FIG. 9, in the portable cooking apparatus of the present invention, as described in detail in FIG. 4, the projection of the locking device is stably coupled to the gap of the upper housing by the elastic part. The lock is not released by the shock.

10 is a view for explaining a comparison of the use form of the drip tray in the portable cooking apparatus of the present invention and the conventional portable cooking apparatus. Referring to (a) of FIG. 10, the conventional portable cooking apparatus is a method in which the oil sump 500 is placed at the bottom of the oil outlet of an inclined fire plate, so that the oil sump is pushed out of its original position and oil spills to the bottom. You can. On the other hand, referring to (B) of FIG. 10, in the portable cooking apparatus of the present invention, since a recessed portion in which the position of the oil pan 500 is fixed is formed on one side of the lower housing, oil can be stably received.

Although not shown in a separate drawing, the portable cooking apparatus of the present invention has an effect of reducing the production cost and heating the plate evenly compared to the conventional horizontally arranged portable cooking apparatus because the structure of the burner is changed. In other words, the conventional portable cooking apparatus has a structure in which the burner portion is positioned horizontally on the left side based on the fuel container, so that the horizontal size of the product is long, and thus the mold investment cost and the amount of the material used are largely used. It is done. On the other hand, the portable cooking device of the present invention is designed so that the burner part is placed on the top of the gas container, and manufactured in a straight plate shape so as not to increase the product height, so that the height of the conventional portable cooking device does not differ significantly, and the flame of the burner part. The shape of the hole (crater) is also in the shape of a 'c' so that it can be transmitted to the entire fire plate, thereby increasing the area where the flame is sprayed to improve heating efficiency. In addition. In the conventional horizontal arrangement type portable cooking apparatus, the effect of cost reduction can be expected by substituting this function with the heat radiated inside without a heat conduction plate that maintains gas vaporization.

The present invention described above is not limited by the above description, and various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention. Those skilled in the art to which the present invention pertains It will be obvious to you.
