Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field This invention is a roaster that collects the smoke and exhaust gas generated when grilling food such as yakiniku. particles) are collected,
The present invention also relates to an oil and fat recovery device for a roaster that uniformly stabilizes the suction pressure acting on the roaster.

Conventional technology Conventionally, in roasters that collect smoke and exhaust gas generated during cooking and exhaust them through exhaust ducts, some roasters have been found to have filters placed in the exhaust path, but in the case of roasters with such a mechanism, The exhaust gas is exhausted by an exhaust fan, and therefore the filter acts as a resistance, reducing the suction pressure and having the disadvantage that the exhaust fan must be made stronger.

In addition, the roaster exhaust path was designed to connect the exhaust part hanging down from the roaster body and the exhaust duct piped horizontally under the floor simply by an elbow curved at right angles, but when the exhaust gas passes through the elbow, it There is a significant difference in flow rate between the circumferential flow path and the outer circumferential flow path, and therefore 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, resulting in satisfactory suction. I couldn't expect any results.

Therefore, a connection box is provided that connects the exhaust section of the roaster body and the exhaust duct in a substantially L-shape, as seen in Publication of Utility Model Publication No. 57-53462. In addition, an exhaust system for a roaster equipped with a static pressure equalizer was developed, which had slits that gradually became wider from the top to the bottom. Due to changes in air pressure and exhaust gas colliding with a portion of the static pressure equalizer (excluding the slit), oil particles adhere to the connection box and the static pressure equalizer, causing damage to the connection box and the static pressure equalizer. Pressure equalizers are fixed and cannot be removed and cannot be cleaned, so they have the disadvantage of accumulating a large amount of oil particles when used for a long period of time, and since the amount of oil particles recovered is small, they are exhausted outside. It has the disadvantage that oil particles get mixed into the exhaust gas, and there is also a risk of a duct fire because oil particles accumulate or get mixed in the connection box, static pressure equalizer, and exhaust duct.

Problems that the invention aims to solve This invention actively collects oils and fats (oil particles) from the exhaust gas by making the exhaust gas complicatedly curved and passing through irregularly shaped openings in the connecting box of the exhaust gas exhaust route. Moreover, it is an object of the present invention to provide an oil and fat recovery device for a roaster in which the adsorbent that adsorbs oil and fat (oil particles) is replaced and the suction pressure acting on the roaster is uniformly made static.

[Structure of the idea]

Means for Solving the Problems The present invention is based on the above-mentioned conventional technology, in which the suction pressure is reduced by collecting oil particles with a filter, and in view of the problems that suction is not uniform throughout the suction part of the roaster, By installing a cylindrical drain pan inside the box, opening an irregularly shaped opening in the drain pan, making the lower part of the drain pan porous, and storing an adsorbent,
The oil particles are induced to adhere to the bottom of the drain pan and the connection box and adsorbed to the adsorbent, and the adsorbent is replaced.
Furthermore, it is an object of the present invention to solve the above-mentioned problem by making the suction pressure acting on the roaster uniform and static.

Function The present invention allows the exhaust gas flow from above to be made to bend in a complicated manner within the connecting box, or to pass through irregularly shaped openings. The oil particles in the drain pan are directly adsorbed by the adsorbent, and the oil particles in the connection box pass through the adsorption holes in the lower part of the drain pan and are adsorbed by the adsorption material, and the drain pan is removed from the connection box. The exhaust gas is removed and the adsorbent is replaced, and the exhaust gas gradually passes through the outer circumferential passage where the suction force is stronger than the inner circumferential passage where it is weaker than the inner circumferential passage where it is weaker because the opening area of the drain pan is wider. The suction pressure acting on the roaster is made uniform at every point in the cross section of the exhaust gas flow path, thereby stabilizing the suction effect of smoke from the roaster body.

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, 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 to face the tapered tube 7. A moving tube 10 that surrounds the outer circumference of the tapered tube 7 and the moving tube 10 is fitted into the outer circumference of the fixed tube 9 so as to be vertically slidable, and the width of the gap 11 created 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 suitably suctioned by a suction device is connected to the connecting member 12.

The connecting box 8 has a volume that is sufficiently larger than the volume required to connect the exhaust section 4 and the exhaust duct 13, and a cylindrical drain pan 14 (cartridge) is removably seated at the bottom of the connecting box 8. The side of the drain pan 14 has an irregularly shaped opening 15, the bottom plate 16 has a large number of suction holes 17, 17a, etc., and the lower inside of the drain pan 14 has an irregularly shaped opening 15. Adsorbent material 18, 18a...
is stored.

The opening 15 of the drain pan 14 is formed so that its opening area is wide in the center and narrow at both ends in a circumferential direction centered on the opposite side of the exhaust duct 13.

In addition, although the punching metal in which the suction holes 17, 17a... are formed in the bottom plate 16 is shown, the suction holes 17, 17a...
17a... are also drilled in the lower part of the side surface of the drain pan 14, and suction holes 17, 17a... in the bottom plate 16...
It may be a long hole that communicates with the hole, or it may be a wire mesh instead of punched metal.

19 is a fitting groove bored on the top plate 20 at the top of the connection box 8 on the exhaust duct 13 side; 21 is a drain pan 14;
It is a stay protruding from the side of the drain pan 14.
When attaching the drain pan 14 to the connecting box 8, fit the stay 21 into the fitting groove 19 and attach the drain pan 14 to the connecting box 8.
is prevented from rotating, but is not limited to this type.

Reference numeral 22 denotes a mesh body that is detachably attached to the inside of the drain pan 14, and the mesh body 22 has an arc shape with approximately 3/4 circumference, while a fitting gap is provided inside the cylindrical portion 23 of the drain pan 14. Upper and lower fitting parts 24, 24 having
a, and both ends of the net 22 are fitted into the fitting portions 24, 24a so that the net 22 covers the opening 15 of the drain pan 14 from the inside.

In addition, 25 is a handle of the drain pan 14, and 26 is a handle of the net body 22.

Next, the function of the oil and fat recovery device in the roaster according to the present invention will be explained. The oil and fat recovery device in the roaster according to the present invention is pulled to a predetermined portion of the roaster body 1 through the connecting box 8, fixed tube 9, moving tube 10, and tapered tube 7 by the suction action of the exhaust duct 13. Since the pressure is applied, the smoke rising from the food on the roaster 3 is sucked together with high-temperature exhaust gas from the top plate 6 and flows from the tapered tube 7 at the bottom of the roaster body 1 to the exhaust duct 1.
Indoor air flows in three directions and mixes in from the gap 11 between the moving tube 10 and the tapered tube 7 which have been adjusted to appropriate positions, 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 15 on the side in the cylindrical drain pan 14, and the oil particles are drawn into the drain pan 14 due to inertia. It falls to the bottom and adheres to or is adsorbed by the adsorbents 18, 18a, .
At this time as well, oil particles fall to the bottom of the connection box 8 due to inertia and turbulence inside the connection box 8, causing the oil particles to fall to the drain pan 14.
The oil particles pass through the suction holes 17, 17a... in the lower part and are adsorbed by the adsorbents 18, 18a... and adhere to the inside of the drain pan 14 and the connection box 8 due to changes in air pressure, and then flow downward to the final state. adsorbent 1
8, 18a..., adsorbent 18, 18a
When a large amount of oil and fat is adsorbed on..., the drain pan 14 is pulled upward from the connection box 8 and the absorbent material 18,
18a... will be replaced.

In addition, in such a flow path, the exhaust gas is absorbed in the outer circumferential flow path (on the opposite side of the exhaust duct 13) where the suction pressure is weaker than in the inner circumference flow path (closer to the exhaust duct 13) where the suction effect is stronger because the area of the opening 15 of the drain pan 14 is larger. Since the passage of the exhaust gas is gradually made easier, 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 connecting box 8 that connects the exhaust section 4 of the roaster body 1 and the exhaust duct 13 in a substantially L-shape, and a cylindrical drain pan that is seated at the bottom of the connecting box 8 in the connecting box 8. 14 is attached removably, and an opening 15 is opened on the side of the drain pan 14. Since the exhaust gas bends in a complicated manner within the connection box 8, oil particles are caused by inertia, turbulence, and changes in air pressure to cause the drain pan to flow. 14 and the bottom of the connecting box 8, etc., and the lower part of the drain pan 14 has a suction hole 1.
7, 17a... were drilled, and adsorbents 18, 18a... were stored in the bottom of the drain pan 14.
The oil particles (oil) that have fallen into the drain pan 14 and the connection box 8 are adsorbed by the adsorbents 18, 18a...
Take out the drain pan 14 and remove the adsorbents 18, 18a.
... can be replaced, and therefore the exhaust gas can be cleaned, the drain pan 14 and the connection box 8 can be cleaned, and unlike a filter, there is no resistance, so a normal exhaust fan can be used. This is possible.

Furthermore, since the opening 15 opens into the drain pan 14 in such a way that the area gradually increases with the center opposite to the exhaust duct 13, the suction pressure acting on the exhaust part 4 of the roaster body 1 is applied to which part of the cross section of the exhaust gas flow path. This makes it possible to stabilize the suction action of the roasted smoke in the roaster body 1.

Furthermore, if the net 22 is removably attached to the opening 15 of the drain pan 14, the net 22 can collect large pieces of roasted vegetables, etc. to the bottom of the drain pan 14, and the net 22 can also prevent oil particles from adhering to the net 22. The practical effects are extremely great, such as being able to clean the exhaust gas by removing the net 22 and cleaning it by taking it out.
