Abstract

The utility model relates to a portable convection multipurpose charcoal roasting oven, which comprises a protective casing, a burning chamber, a drill rod and roasting plate, wherein, the burning chamber is fixed in the protective casing, and the bottom and the side wall of the burning chamber are both separated from the protective casing by partition devices for air ventilation, wherein, the bottom and side wall are both provided with air ventilating holes. The utility model can supply sufficient and uniform air for charcoal burning of which the flame is not affected by crosswind, and can form burning supported by aqueous vapor. With the advantages of high thermal efficiency, suitable for carrying, safe usage, and sanitary and clean use, the utility model is a favorable tool for household or field roasting.

Description

Portable convection multipurpose charcoal roasting oven

The utility model relates to a kind of baking oven, and particularly a kind of portable convection type is used charcoal brazier more.

Existing portable charcoal baking oven mostly is self-control among the people, and charcoal is when burning, and the hole of portion of air grate below the charcoal layer enters the combustion chamber, and another part air then contacts with the charcoal layer in the above and participates in burning, and its defective is as follows:

1) uniformity coefficient supplied with of air is affected by environment bigger when burning, and the place's burning of nearly air port, grate bottom is strong, away from the air inlet place then a little less than.

2) through burning after a while, a part of charcoal ash stops up fire door, makes air under-supply, and people have to incite with fan, powerful air feed, and this moment, charcoal was disorderly greatly, and sparks are flying in all directions, dangerous, unhygienic, inconvenience.

When 3) the charcoal grate firing burns, stronger radiation is arranged downwards, so its safe distance must increase the oven height greater than 200mm, volume increases, and uses and carry equal inconvenience.

The purpose of this utility model provides a kind of fuel thermal efficiency that improves, and burning is not subjected to ectocine, and health, safety, portable convection type is used charcoal brazier more easily.

The utility model is achieved in that the combustion chamber is fixed in the upper and lower uncovered protective cover, its bottom surface and sidewall all and between the protective cover have the interval that can ventilate, form air chamber, uncovered relative with the protective cover upper shed above the combustion chamber, bottom surface, combustion chamber and sidewall all have passage.

The utility model process is tested, and effect is comparatively desirable, and its maximum characteristics are that charcoal air when burning is supplied with abundant, even.After charcoal is ignited, thermograde around it forms the cross-ventilation condition, when hot gas rises, air enters the combustion chamber by the passage of bottom surface, combustion chamber and side, under the blocking of protective cover, air can only enter in the air chamber that is formed by combustion chamber and protective cover from the protective cover bottom, therefore burning is not influenced by crosswind can, passage can not stop up yet, and has guaranteed the unimpeded of combustion air, and thermal field is evenly distributed, when adding charcoal, the utility model begins to ignite from top, red charcoal is placed on the superiors, can be very fast lower floor's black wood charcoal be ignited, when adding new charcoal, red charcoal is concentrated in together, new charcoal is placed on by the red charcoal, and new charcoal can be ignited very soon, and the utilization rate of this mode charcoal burning is the highest.Basin structure of the present utility model has ensured the safety of using, even water has been opened and has not also been had the fire generation, the steam of the water generates after the heating with fill the air after air mixes upwards, enter the combustion chamber very uniformly, hydrone is met Pintsch process, combustion efficiency is better, and the use of basin has reduced height of the present utility model, uses and carry to become more convenient.The utility model supporting structure makes comburant and oven that certain distance be arranged, and can keep the baking equipment cleaning.

Description of drawings:

Fig. 1 is the structure cutaway view of the utility model embodiment 1;

Fig. 2 is the structure cutaway view of the utility model embodiment 2.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment 1:

The utility model as shown in Figure 1, combustion chamber 4 is fixed in the upper and lower uncovered protective cover 3, its bottom surface and sidewall are all and the interval that can ventilate arranged between the protective cover 3, combustion chamber 4 is supported by support column 5 with protection 3 and is isolated in the present embodiment, form air chamber 10, uncovered relative above the combustion chamber 4 with protective cover 3 upper sheds, 4 bottom surfaces, combustion chamber and sidewall all have passage 9, under the blocking of protective cover, air can only enter air chamber 10 from protective cover 3 bottoms, and therefore burning is not influenced by crosswind can.Both sides, protective cover 3 top have gripper shoe 6, and it can make roasting thing of combustion and oven that certain distance is arranged, and when barbecue dish 8 uses, directly places on the gripper shoe 6, makes Korea's barbecue or Mongolia's barbecue, also can be used for Hot dishes during picnic, makes soup, even can make frying pan and use.Protective cover 3 lower ends have bracket with foldable 2, and support 2 is made by wire, and there is a basin 1 in the space that forms with 4 bottoms, combustion chamber in support 2, it is positioned at the position of 4 bottoms over against the combustion chamber, support 2 can be turned up when not using, and reduces volume of the present utility model, is easy to carry.

Embodiment 2:

The utility model as shown in Figure 2, do not implement support 2 structures in 1, but in protective cover 3, there is a supported post 5 to be fixed on basin 1 on protective cover 3 sidewalls, its position is 4 bottoms over against the combustion chamber, this structure of the present utility model is very obvious for the combustion-supporting effect of steam and air mixing back generation, therefore it is better than embodiment 1 on combustibility, but implement 1 and be better than embodiment 2 aspect collecting and carrying, other structure of present embodiment is identical with embodiment 1, here no longer repeats.
