Abstract

A stand-alone filtering apparatus for use with indoor barbecuing includes a base configured for the reception of a heating assembly and a filter unit which is selectively positionable in a vertical direction relative to the base. The filter unit includes a filtering element for removing contaminants from a medium as the medium passes therethrough and a ventilation system for creating an air flow for drawing the medium and the contaminants through the filtering element.

Claims

1. A filtering apparatus for use during indoor cooking, comprising:

a base configured for the reception of a heating assembly; and

a filter unit positioned in a plane substantially parallel to a plane in which the base lies, the filter unit being selectively positionable in a vertical direction relative to the plane of the base, the filter unit including;

a filtering element for removing contaminants from a medium as the medium passes therethrough; and

a ventilation system for drawing the medium and contaminants through the filtering element.

2. A filtering apparatus according to claim 1 wherein the filter unit includes a hinge which permits pivotable movement of the filter unit relative to the base.

3. A filtering apparatus according to claim 1 wherein the base includes a post which extends therefrom and the filter unit includes a sleeve which telescopically engages the post to allow for selective, vertical positioning of the filter unit relative to the base.

4. A filtering apparatus according to claim 3 wherein the post includes a hinge which allows for pivotable movement of the post relative to the base.

5. A filtering apparatus according to claim 4 wherein the hinge allows the base to fold against the post for storage purposes.

6. A filtering apparatus according to claim 3 wherein the sleeve includes at least one locking tab for selectively positioning and locking the filter unit relative to the base.

7. A filtering apparatus according to claim 1 wherein base includes a support rack having an inner periphery which defines an aperture configured for the reception of the heating assembly.

8. A filtering apparatus according to claim 1 wherein the heating assembly includes a grill plate.

9. A filtering apparatus according to claim 1 wherein the heating assembly includes a rotisserie.

10. A filtering apparatus according to claim 1 wherein the filtering element is removable from the filter unit for cleaning or replacement.

11. A filtering apparatus according to claim 1 wherein the ventilation system includes a motor which operates at least one fan for creating an air flow to draw the medium and contaminants through the filtering element.

12. A filtering apparatus according to claim 11 wherein the motor includes a switch which regulates the speed of the fan and the resulting air flow of the medium and contaminants through the filtering element.

13. A stand-alone filtering apparatus for use during indoor cooking, comprising:

a base configured for the reception of a heating assembly, the base including a post which extends upwardly from a rear portion of the base; and

a filter unit positioned in a plane substantially perpendicular to a plane in which the base lies, the filter unit having;

a filtering element for removing contaminants from a medium as the medium passes therethrough;

a ventilation system for creating an air flow for drawing the medium and the contaminants through the filtering element; and

a sleeve which telescopically engages the post of the base for allowing selective vertical positioning of the filter unit relative to the plane of the base.

14. A filtering apparatus according to claim 13 wherein the filter unit includes a hinge which permits pivotable movement of the filter unit relative to the base.

15. A filtering apparatus according to claim 13 wherein the post includes a hinge which permits pivotable movement of the post relative to the base.

16. A filtering apparatus according to claim 13 wherein the filter unit includes a hood having an intake chamber defined therein, the intake chamber being configured for selective reception and engagement of the filtering element therein.

17. A foldable filtering apparatus for use with a cooking device, comprising:

a base including a support rack having an inner periphery which defines an aperture configured for the reception of the cooking device, the base including a post which extends upwardly from a rear portion of the base; and

a filter unit positioned in a plane substantially parallel to a plane in which the base lies, the filter unit being selectively positionable in a vertical direction from a first position relative to the plane of the base to a second position further from the base, the filter unit including;

a hood having an intake chamber defined therein;

a filtering element for removing contaminants from a medium as the medium passes therethrough, the filtering element configured for selective engagement within the intake chamber;

a ventilation system for creating an air flow for drawing the medium and contaminants through the filtering element; and

a hinge which connects the filter unit with the post for permitting pivotable movement of the filter unit relative to the base.

18. A filtering apparatus for use with a cooking device, comprising:

a base including a support rack having an inner periphery which defines an aperture configured for the reception of the cooking device, the base including a post which extends upwardly from the rear portion of the base; and

a filter unit which is selectively positionable in a vertical direction from a first position relative to the base to a second position further from the base, the filter unit and base being in substantially parallel planes in said first and second positions, the filter unit including;

a hood consisting of a ventilation housing, a lower intake expansion and an outer rim for defining an intake chamber therein, which serves to capture contaminants;

a filtering element for removing contaminants from the contaminants as the contaminants pass therethrough, the filtering element configured for selective engagement within the intake chamber;

a ventilation system for creating an air flow for drawing the medium and contaminants through the filtering element; and

a hinge which connects the filter unit with the post extending downwardly from the rear portion of the filter unit for permitting pivotable movement of the filter unit relative to the base.
