Abstract

Apparatus and related methods for adding increased functionality to a food dehydrator through the use of stackable drying trays that define a circulation plenum during operation and then nest within one another during disassembly so as to reduce an overall storage size of the food dehydrator. The food dehydrator can further include a base portion having a removable splash guard to prevent the introduction of liquids or solids into a mechanical space within the base portion.

First claim

The invention claimed is:

1. A food dehydrator comprising:
a base portion including an upper base surface defining a base central aperture, a base circumferential inner wall, and a base circumferential outer wall, the base circumferential inner wall and the base circumferential outer wall defining a base perimeter channel;
a carrying tray including a carrying tray upper surface defining a carrying tray central aperture, an interior surface, an upper channel surface having one or more apertures, and an exterior surface defining a carrying tray perimeter channel; and
a cover portion,
wherein the carrying tray is configured for liftable placement on the upper base surface of the base portion to define a dehydrating configuration such that the interior surface of the carry tray is proximate to the base circumferential inner wall of the base portion, the exterior surface of the carrying tray is proximate to the base circumferential outer wall, and the carrying tray perimeter channel and the base circumferential perimeter channel align and cooperatively define an air supply plenum, and
wherein the cover portion is configured for liftable placement on the carrying tray such that the cover portion fluidly encloses the air supply plenum in the dehydrating configuration; and
wherein the carrying tray is configured upon inversion for liftable placement on the upper base surface of the base portion to define a storage configuration, such that the interior surface of the carrying tray is proximate to the base circumferential inner wall of the base portion, the exterior surface of the carrying tray is proximate to the base circumferential outer wall, and the carrying tray perimeter channel is at least partially nested within the base perimeter channel.

2. The food dehydrator of claim 1 , further comprising:
a tray portion including a tray portion central aperture and a tray portion air supply plenum, wherein the tray portion is configured for liftable placement on the first carrying tray such that the air supply plenum is fluidly engaged with the tray portion air supply plenum and wherein the cover portion is liftably placeable on the tray portion to enclose the tray portion air supply plenum.

3. The food dehydrator of claim 2 , wherein the tray portion comprises:
a second tray having a second tray central aperture and a second tray perimeter channel; and
a second carrying tray structurally identical to the carrying tray,
wherein the carrying tray perimeter channel of the second carrying tray and the second tray perimeter channel cooperatively define the tray portion air supply plenum.

4. The food dehydrator of claim 2 , wherein the tray portion is individually liftable from the carrying tray such that the air supply plenum remains defined between the base portion and the carrying tray.
