Abstract

A splatter guard device is adapted for use inside a cooking chamber of a conventional microwave oven to inhibit splattering of cooking foodstuffs about the cooking chamber. The splatter guard device comprises a cover and a support structure. The cover is sized to extend longitudinally and laterally within the cooking chamber of the microwave oven to at least cover the cooking foodstuffs. The support structure is adapted to be secured in a manner within the cooking chamber of the microwave oven so that the support structure is operative to releasably retain the cover above and proximate to the cooking foodstuffs to inhibit splattering of the cooking foodstuffs about the cooking chamber.

Claims

1. A splatter guard device adapted for use within a cooking chamber of a conventional microwave oven to inhibit splattering of foodstuffs cooking in an open container disposed therewithin, the cooking chamber defined by a rear wall, two opposing side walls, an inner door surface of a closed front door, a floor and a ceiling, comprising:

(a) a body member fabricated from a material transparent to microwaves, said body member extending substantially between the floor and the ceiling of the cooking chamber of the microwave oven and adapted to abut the rear wall thereof, said body member formed with an array of slots extending laterally and substantially parallel to each other and facing the cooking chamber;

(b) a substantially flat cover fabricated from a material transparent to microwaves, said cover extending longitudinally and laterally within the cooking chamber of the microwave oven and terminating in an outer peripheral edge portion disposed proximate to the rear wall, the two opposing side walls and the inner door surface of the closed front door; and

(c) a pair of arms oppositely disposed on and movably connected to an upper portion of said body member, said pair of arms operative to move between a detached position whereby said body member is detached from said respective opposite side walls by retracting said pair of arms from contact with the respective side walls within the cooking chamber and an anchor position whereby said body member is mounted within the cooking chamber by extending said pair of arms in contact with respective opposite side walls so that, in the anchor position, said cover can be releasably inserted into a select one of said plurality of slots to retain said cover in a substantially horizontal position above and proximate to the open container of cooking foodstuffs to inhibit splattering of the cooking foodstuffs about the cooking chamber.

2. A splatter guard device according to claim 1 including a pair of shoulders projecting from and connected to an upper portion of said body member to define a T-shape, each of said shoulders adapted to matably receive a respective one of said arms.

3. A splatter guard device according to claim 2 including a pair of opposite end portions connected to a respective shoulder, each end portion having a threaded hole extending therethrough and wherein each of said arms includes a threaded shaft and a cup element connected to a distal end of said threaded shaft, each of said threaded shafts formed to matably engage a respective one of said threaded holes of said end portions of said shoulders so that, upon rotating said arms in a fastening direction, said arms extend into the anchoring position whereby each of said cup elements engage a respective one of said opposing side walls and, upon rotating said arms in a detaching direction opposite the fastening direction, said arms retract into the detached position thereby disengaging said cup elements from respective opposite side walls.

4. A splatter guard device according to claim 1 including a pair of legs connected to a lower portion of said body member and adapted to elevate said body member above said floor within the cooking chamber.

5. A splatter guard device according to claim 1 including a pair of pillar portions projecting into the cooking chamber toward said inner door surface and extending vertically along said body member, each of said pillar portions disposed on opposite sides of said array of slots and operative to contact a bracing segment of said peripheral edge portion of said cover.

6. A splatter guard device according to claim 1 wherein including a tongue element projecting outwardly from said outer peripheral edge portion of said cover and adapted to be releasably inserted into a select one of said array of slots.

7. A splatter guard device according to claim 1 wherein said body member is constructed as a unitary piece.

8. A splatter guard device adapted for use within a cooking chamber of a conventional microwave oven to inhibit splattering of foodstuffs cooking in an open container disposed therewithin, the cooking chamber defined by a rear wall, two opposing side walls, an inner door surface of a closed front door, a floor and a ceiling, comprising:

(a) a substantially flat cover fabricated from a material transparent to microwaves, said cover extending longitudinally and laterally within the cooking chamber of the microwave oven and terminating in an outer peripheral edge portion disposed adjacent to the rear wall, the two opposing side walls and the inner door surface; and

(b) a support structure mounted within the cooking chamber, said support structure including a belt and pulley assembly having a U-shaped retaining element connected thereto, said U-shaped retaining element having a U-shaped channel facing the cooking chamber and having a channel axis extending through said U-shaped channel and being oriented in a substantially parallel relationship with respect to one of the floor and the ceiling, said U-shaped channel sized to releasably receive said peripheral edge portion of said cover to retain said cover to said U-shaped retaining element, said U-shaped retaining element of said belt and pulley assembly operative to move vertically within the cooking chamber so that said cover may extend horizontally within the cooking chamber over the cooking foodstuffs to inhibit splattering of the cooking foodstuffs about the cooking chamber.

9. A splatter guard device according to claim 8 wherein said belt and pulley assembly includes a pair of mounting blocks, a pair of pulleys and a continuous belt operably interconnecting said pulleys, each of said mounting blocks having a respective pulley rotatably connected thereto about respective axis of rotation, said continuous belt connected to said U-shaped retaining element so that when said cover is releasably retained by said U-shaped retaining element, said cover can be moved vertically within the cooking chamber in a horizontal position to a select location between said pulleys.

10. A splatter guard device according to claim 9 wherein said belt and pulley assembly is mounted behind the rear wall and wherein said rear wall includes a rear wall slot so that the U-shaped retaining element can be disposed into said cooking chamber while being connected to said belt behind said rear wall slot and vertically movable between said pulleys.

11. A splatter guard device according to claim 10 including at least one friction pad disposed between said pulley and said mounting block of said belt and pulley assembly, said friction pad operative to prevent rotational movement of said pair of pulleys when said cover is releasably retained by said U-shaped retaining element in the horizontal position at the select vertical location between said pair of pulleys.
