Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field This invention is a roaster that collects smoke and exhaust gas generated when grilling food such as yakiniku, and uses it to uniformly apply suction pressure to the roaster. This invention relates to an exhaust device for a roaster that creates static pressure, collects oil particles from combustion smoke and exhaust gas, and allows a drain pan with oil particles to be detachably attached and cleaned.

Conventional technology Conventionally, the roaster exhaust path was constructed by simply connecting the exhaust section hanging down from the roaster body and the exhaust duct piped horizontally under the floor with an elbow curved at right angles. When passing through, there is a significant difference in the flow rate between the inner circumferential flow path and the outer circumferential flow path, so the pull is strong at the burnt smoke suction position of the roaster body corresponding to the inner circumferential flow path, while the pull is weak at the position corresponding to the outer circumferential flow path. However, I could not expect a satisfactory suction effect.

Therefore, Utility Model Publication No. 57-53462 or Japanese Unexamined Patent Application Publication No. 57-57-
A connection box is provided that connects the exhaust part of the roaster body and the exhaust duct in a substantially L-shape as seen in Publication No. 75620, and the connection box is inscribed so as to divide the exhaust gas flow path in an inclined manner, and extends from the top to the bottom. An exhaust system for a roaster was developed that was equipped with a static pressure equalizer with slits that gradually became wider towards the end. This is due to the fact that the exhaust gas collides with a part of the static pressure equalizer (excluding the slit).
Oil particles adhere to the connection box and static pressure equalizer,
Since such connection boxes and static pressure equalizers are fixed and cannot be removed or cleaned, they have the disadvantage that a large amount of oil particles accumulate during long-term use, and the recovery effect of the oil particles is small. It has the disadvantage that oil particles get mixed into the exhaust gas exhausted outdoors,
In addition, there was a risk of a duct fire because oil particles accumulated or were mixed in the connection box, static pressure equalizer, and exhaust duct.

Problems to be solved by the invention The invention provides a connection box that connects the exhaust part of the roaster main body and the exhaust duct in a substantially L-shape. By passing through the roaster, the suction pressure acting on the roaster is uniformly made static, and the smoke and
To provide an exhaust device for a roaster that actively collects oil particles from exhaust gas and allows a drain pan on which oil particles are attached to be detachably attached and cleaned.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention provides an exhaust system for a roaster that is provided with a connection box that connects the exhaust section of the roaster main body and the exhaust duct in a substantially L-shape. An exhaust system for a roaster that is equipped with a drain pan that is detachably attached to the side surface and has an opening that gradually increases in area centering on the opposite side of the exhaust duct, and an exhaust system for a roaster that is equipped with a mesh body that is detachably attached to the opening of the drain pan. The present invention is intended to solve the above-mentioned drawbacks.

Function The present invention allows the exhaust gas flow from above to be made to bend in a complicated manner within the connection box, or to pass through irregularly shaped openings. The wide area of the opening gradually makes it easier for the exhaust gas to pass through, and the suction pressure acting on the exhaust part of the roaster body is made uniform at every point in the cross section of the exhaust gas flow path, which reduces the amount of smoke in the roaster body. In addition to stabilizing the suction effect, since the exhaust gas bends in a complicated manner within the connection box, oil particles accumulate on the drain pan and the bottom of the connection box due to inertia, turbulence, and changes in air pressure, thus making it difficult to clean the exhaust gas. Once completed, remove the drain pan from the connection box and clean the drain pan and connection box.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a roaster main body for grilling food such as yakiniku, a roaster 3 for placing food on a table 2 is attached approximately in the center of the table 2; Around it is an intake hole 5 that communicates with the exhaust part 4 at the bottom of the roaster main body 1.
A top plate 6 having a top plate 6 is attached thereto, and a tapered tube 7 tapered downwardly is connected to the exhaust section 4.

Reference numeral 8 designates a connection box located below the tapered tube 7, on which a fixed tube 9 having approximately the same diameter as the large diameter portion of the tapered tube 7 is erected so as to face the tapered tube 7. A moving tube 10 surrounding the outer periphery of the fixed tube 9 is fitted into the outer periphery of the fixed tube 9 so as to be vertically slidable, and the width of the gap 11 caused by the diameter difference between the tapered tube 7 and the moving tube 10 can be adjusted by vertical sliding. There is.

Further, a connecting member 12 is provided protruding from the side surface of the connecting box 8, and an exhaust duct 13 which is suctioned by an appropriate suction device is connected to the connecting member 12.

The connecting box 8 has a volume sufficiently larger than that required to connect the exhaust section 4 and the exhaust duct 13,
The inside has a cylindrical shape with a bed and an irregularly shaped opening 1 on the side.
A drain pan 15 having an opening 4 is removably attached to the opening 14 of the drain pan 15.
The opening area is formed in the circumferential direction centering on the opposite side of the exhaust duct 13 such that the opening area is wide at the center and narrow at both ends and gradually increases in area.

A tapered collar 16 is provided at the upper end of the drain pan 15.
At the same time, a tapered placing part 17 is formed at the upper end of the connecting box 8, and a collar 16 is placed on the placing part 17, so that the drain pan 15 is mounted inside the connecting box 8.

In addition, on the exhaust duct 13 side, the collar 1 of the drain pan 15
6 to protrude inward in a planar manner, and the drain pan 1
The cylindrical portion 18 of the connecting box 8 is formed into a planar shape, and the mounting portion 17 of the connecting box 8 is made to project inward in a planar manner to prevent the drain pan 15 from rotating in the connecting box 8. Not limited.

Reference numeral 19 denotes a net body that is detachably attached to the inside of the drain pan 15. The net body 19 has an arc shape with about 3/4 circumference, and on the inside of the flat part of the cylindrical part 18 of the drain pan 15, there is a Upper and lower fitting parts 20 having a gap,
20a is provided and the mesh body 1 is inserted into the fitting portions 20, 20a.
9 into the opening 14 of the drain pan 15.
The net body 19 covers it from the inside.

In addition, 21 is a handle of the drain pan 15, and 22 is a handle of the net body 19.

Next, the action of the exhaust system in the roaster according to the present invention will be explained. The suction action of the exhaust duct 13 draws pressure into a predetermined portion of the roaster body 1 via the connecting box 8, fixed tube 9, moving tube 10, and tapered tube 7. As a result, the smoke rising from the food on the roaster 3 is sucked together with high-temperature exhaust gas from the top plate 6 and is sent from the tapered tube 7 at the bottom of the roaster body 1 to the exhaust duct 1.
Indoor air is mixed in between the moving tube 10 and the tapered tube 7, which flow in three directions and are adjusted to appropriate positions, from the space 11, thereby cooling the exhaust gas and optimizing the suction pressure to the roaster body 1.

When the exhaust gas is sucked in this way, inside the connection box 8, the exhaust gas flow from above is bent at right angles to the opening 14 on the side inside the cylindrical drain pan 15, and the oil particles are drawn into the drain pan 15 due to inertia. If it sticks to the bottom or accumulates, or after passing through the drain pan 15, it bends inside the connection box 8 and is exhausted from the exhaust duct 13, and at this time, the bottom of the connection box 8 is also caused by inertia and turbulence inside the connection box 8. Oil particles adhere to or accumulate in the drain pan 15 and connection box 8 due to changes in air pressure, and in these flow paths, exhaust gas flows through the inner circumferential flow path (closer to the exhaust duct 13) where the suction force is strong. Drain pan 15 in the outer circumferential flow path (on the opposite side of exhaust duct 13) which is weaker than
The large area of the opening 14 gradually makes the exhaust gas passage easier, so that the exhaust gas from the roaster body 1 is sucked in at the same flow rate at every point in the cross section.

[Effect of idea]

In short, the present invention provides a connection box 8 that connects the exhaust section 4 of the roaster body 1 and the exhaust duct 13 in a substantially L-shape. By connecting the horizontal exhaust flow paths in the duct 13, exhaust gas generated during cooking can be discharged outside the store, and the roaster main body 1 can be converted into a smokeless roaster.

In addition, a drain pan 15 is removably installed in the connecting box 8 in a cylindrical shape with a bed and having an opening 14 that gradually increases in area centered on the opposite side of the exhaust duct 13, so that the first effect can be achieved. As a result, the suction pressure acting on the exhaust part 4 of the roaster body 1 is made uniform at any point in the cross section of the exhaust gas flow path, and the suction effect of smoke in the roaster body 1 can be stabilized.

The second effect is that the exhaust gas bends in a complicated manner within the connection box 8, so oil particles accumulate on the drain pan 15 and the bottom of the connection box 8 due to inertia, turbulence, and changes in air pressure. It can be cleaned, and since the drain pan 15 is removable, it can be removed from the connection box 8 and the drain pan 15 and connection box 8 can be removed.
Therefore, with the above structure, it is possible to achieve uniform static suction pressure and to facilitate cleaning of the inside of the connection box 8 at the same time.

Furthermore, since the net 19 is detachably attached to the opening 14 of the drain pan 15, oil particles can also be attached to the net 19 to clean the exhaust gas, or the net 19 can be taken out and cleaned.

Furthermore, since the mounting portion 17 of the connection box 8 and the collar 16 of the drain pan 15 are tapered, the fixed tube 9
The practical effects of this, such as the oil adhering to the drain pan 15 flowing down into the drain pan 15, are enormous.
