Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial field of application This invention is designed to remove smoke, oil particles, exhaust heat, etc. generated during grilling of skewers such as barbeques without the need for a hood or ventilation fan. This relates to a smokeless skewer that is completely recyclable.

Conventional technology Traditionally, such skewers were placed inside the store, and a hood was installed above the skewer or a ventilation fan was installed on the wall to exhaust smoke, oil particles, exhaust heat, etc. generated during skewering to the outside of the store. However, because there is a gap between these exhaust devices and the skewer, it is impossible to completely recover smoke, etc., and exhaust gas accumulates inside the store. This has the disadvantage that the air conditioning load increases because the conditioned air inside the store is exhausted together with the exhaust gas.

Problems that the invention aims to solve This invention places a grill inside the outer box that is subjected to suction, and sucks the exhaust gas, which is a mixture of burning smoke, oil particles, exhaust heat, etc. on the grill, into the inside of the skewer body. By exhausting through the exhaust duct, the exhaust gas generated during skewering is completely recovered, and the air above the grill is sucked in through the intake holes in the top plate placed on the side of the grill. To provide a smokeless skewer that sucks only a small amount of air-conditioned air and does not increase the heating and cooling load.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention has an outer box that is suctioned by the skewer body, and an inner box that has suction passages at a predetermined interval inside the outer box. In addition to providing a heating section with a heat insulating material around the inside of the box, a grilling net is placed above the inner box, and grooves are provided on the outside of the grilling net positioned below the grilling net. A top plate that covers the upper opening of the box is removably placed on the outer box, and a predetermined number of intake holes are formed through the hanging wall of the top plate, or a combination of two or more of the above skewer bodies. The present invention aims to solve the above-mentioned drawbacks by providing a smokeless skewer.

Function The present invention proposes that when skewered food is placed on a grill with the handles of barbeques and other skewered food on a concave groove and grilled in the heating section, when a suction pressure is applied to the outer box, the food is cooked. The smoke on the grill that rises as the food is being baked is sucked together with a small amount of indoor air through the suction channel in the outer box through the intake holes that penetrate the top plate located around the grill. It is exhausted to the outside.

In addition, since the concave grooves are located on the outside of the grill, the handle part is not heated by the heating part, and furthermore, the heat conduction from the heating part to the handle part is prevented by the insulation effect of the insulating material surrounding the heating part. It blocks out.

Next, to explain the operation of the smokeless skewer according to the present invention, the cooked food 49 of the skewered food 47 such as barbecue is placed on the grill 22 with the handle 48 of the skewered food 47 above the grooves 15, 15a. , the ceramic charcoal 23, 23a... is heated by igniting the burner 25,
As a result, the far infrared rays emitted from the ceramic charcoal 23, 23a... and the ceramic charcoal 23, 23
a... The food 49 on the upper grill 22 is grilled by direct fire passing through the space between them, while the skewered food 4
Since the handle part 48 of No. 7 is disposed on the grooves 15 and 15a located on the outside of the gridiron 22, the handle part 48 is not heated by the heating part 16, and is further not heated by the inner wall of the charcoal pot case 19 in the heating part 16. Installed insulation material 1
8, the heating section 16 is heated to the handle section 48.
It blocks heat conduction to the

During such baking, when suction pressure is applied to the outer box 5 through the exhaust section 7 by the exhaust device 37,
The smoke on the grill 22 that rises as the food is grilled is discharged along with a small amount of indoor air from the air intake holes 32, 32a, which are penetrated through the top plates 28, 28a located around the grill 22, into the outer box. 5 through the suction channel 8 and from the exhaust section 7 to the exhaust device 37.
It is exhausted.

When the moving tube 42 is lowered to create a gap 43 between the moving tube 42 and the tapered tube 39 when the exhaust gas passes through the exhaust device 37, indoor air flows from the gap 43 as the exhaust gas flows from the tapered tube 39 toward the exhaust duct. The exhaust gas is cooled and the suction pressure applied to the skewer body 4 is optimized.

When the exhaust gas is sucked in this way, the connecting box 4
0, the exhaust gas flow rate is suppressed because the width of the slit 45 of the static pressure equalizer 46 is narrow in the inner circumferential flow path A where the suction force is strong, while the width of the slit 45 becomes wider toward the outer circumference flow path B where the suction force is weaker. This makes it easier for the exhaust gas to pass through gradually, so that the exhaust gas from the skewer body 4 is sucked in at the same flow rate at every point on the cross section.

[Effect of idea]

In short, the present invention includes an outer box 5 that is suctioned by the skewer main body 4 and an inner box 9 that is attached to the outer box 5 so as to have suction passages 8 at predetermined intervals.
A heating part 16 with a heat insulating material 18 surrounding it is provided inside the box, and a grill 22 is placed above the inner box 9.
Concave grooves 15, 15a are provided on the outside of the grill 22 positioned below the grill 22, and top plates 28, 28a that cover the upper opening 30 of the outer box 5 are detachably attached to the outer box 5. At the same time, a predetermined number of intake holes 32,
32a... are installed through the top plates 28, 28a located above and around the grill 22, so that the smoke on the grill 22 that rises as the food 49 is grilled is removed together with a small amount of indoor air through the top plates 28, 28a located around the upper part of the grill 22. Since the air intake holes 32, 32a... are sucked in through the suction channel 8 of the outer box 5 and exhausted to the outside, a clean air environment can be created without exhaust gas filling the store. Therefore, it is possible to make skewer cooking such as barbecue smokeless, and since the amount of indoor air conditioned air sucked is smaller than in the past, the load on heating and cooling can be reduced.

In addition, since the grooves 15 and 15a are located outside the grill 22, the food on the skewers 47 can be placed on the grill 22 and the handle 48 can be placed on the grooves 15 and 15a. Since these are not heated by the heating section 16, the skewers 47 can be turned over during cooking without using glove-like handles or the like, and the skewers 47 that have been baked can be held. is recessed below the grill 22, so the skewers 47
The handle part 48 of the heating part 16 is easy to grip, and the heating part 16 is
This reliably blocks heat conduction from the handle portion 48 to the handle portion 48.

In addition, since two or more of the above-mentioned skewer bodies 4, 4a are combined, the skewer body 4 can be used efficiently and without waste, depending on the number of people serving meals, whether large or small, resulting in great practical effects. It is what it is.
