BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to stationary food dehydrators and more particularly pertains to a new rotating food dehydrator for preparing meat jerky and other dehydrated foods.

2. Description of the Prior Art

The use of stationary food dehydrators is known in the prior art. More specifically, stationary food dehydrators heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

Known prior art stationary food dehydrators include U.S. Pat. No. 5,437,108; U.S. Pat. No. 5,423,249; U.S. Pat. No. 3,943,842; U.S. Pat. No. 5,440,825; U.S. Pat. No. 4,152,842; and U.S. Pat. Des. 252,397.

In these respects, the rotating food dehydrator according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of preparing meat jerky and other dehydrated foods.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of stationary food dehydrators now present in the prior art, the present invention provides a new rotating food dehydrator construction wherein the same can be utilized for preparing meat jerky and other dehydrated foods.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new rotating food dehydrator apparatus and method which has many of the advantages of the stationary food dehydrators mentioned heretofore and many novel features that result in a new rotating food dehydrator which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art stationary food dehydrators, either alone or in any combination thereof.

To attain this, the present invention generally comprises a base with a rectangular configuration including a rectangular bottom face. A side wall is coupled to a periphery of the bottom face and extended upwardly therefrom for defining a rectangular upper peripheral edge and an interior space. The side wall is defined by a pair of short end faces and a pair of elongated side faces. The side wall has an arcuate inner wall defining a portion of a cylinder mounted therein between the end faces of the base. Note FIG. 5. Each of the faces of the base has an input vent and an output vent formed therein adjacent to the bottom face of the base. See again FIG. 5. Next provided is a cover including a pair of side faces each with a semicircular configuration and an arcuate top face. Such top face defines a portion of a cylinder similar to that defined by the arcuate inner wall of the base, as shown in FIG. 5. The cover further includes a lower peripheral edge being removably situated over the base. In use, the lower peripheral edge of the cover resides in engagement with the upper peripheral edge of the base for defining a compartment. With reference still to FIG. 5, a fan assembly is shown to include a bottom fan mounted to the bottom face of the base adjacent to the input vent. The bottom fan serves for directing air through the base and toward the output vent upon actuation. Associated therewith is a plurality of upright fan assemblies each including a tube connected between vents formed in the bottom face and the inner wall of the base. Each of such tubes has a lower vertical extent and an upper arcuate extent such that the associated fan directs air in a first rotational direction along the inner wall of the base upon actuation. The fan assembly further includes a plurality of circularly configured fans each mounted to the top face of the cover and the inner wall of the base within the compartment. The fan assembly is adapted for directing air in the first rotational direction upon the actuation thereof. Next provided is a heating assembly mounted over the vents formed in the inner wall of the base.

FIGS. 3 & 4 show a rotisserie assembly situated within the compartment and including an axle rotatably mounted between central extents of the side faces of the base adjacent to the upper peripheral edge thereof. Two sets of radially extending arms each have an inboard end coupled to a corresponding end of the axle and resides in a common plane. A pair of annular members are each coupled to outboard ends of the radially extending arms of an associated one of the sets. For supporting food thereon, a plurality of trays are each rotatably mounted between a pair of the radially extending arms. The rotisserie has a motor associated therewith for rotating the trays about the axle in a second rotational direction opposite the first rotational direction upon the actuation thereof. Situated within the compartment is a thermostat for detecting a temperature therein. As shown in FIG. 1, a control panel is mounted on one of the side faces of the base with a display for displaying a current temperature within the compartment. The display actuates the heating assembly and the motor of the rotisserie for a predetermined time period in use. When actuated, the heating assembly is governed so as to remain below a preset temperature.

The side wall is defined by a pair of short end faces and a pair of elongated side faces. The side wall has an arcuate inner wall 18 which defines a portion of a cylinder mounted therein between the end faces of the base. Note FIG. 5. Each of the end faces of the base has an input vent 20 and an output vent 22 formed therein adjacent to the bottom face of the base. See again FIG. 5.

Next provided is a cover 23 including a pair of side faces each with a semicircular configuration and an arcuate top face. Such top face defines a portion of a cylinder similar to that defined by the arcuate inner wall of the base, as shown in FIG. 5. The cover further includes a lower peripheral edge being removably situated over the base. In use, the lower peripheral edge of the cover resides in engagement with the upper peripheral edge of the base for defining a compartment. Optionally, a locking assembly may be employed to further secure the cover to the base. It should be further noted that the base and cover may be constructed from any type of transparent, opaque plastic or the like.

With reference still to FIG. 5, a fan assembly is shown to include a bottom fan 24 mounted to the bottom face of the base adjacent to the input vent. The bottom fan serves for directing air through the base and toward the output vent upon actuation. Associated therewith is a plurality of upright fan assemblies 25 each including a tube connected between vents formed in the bottom face and the inner wall of the base. Each of such tubes has a lower vertical extent and an upper arcuate extent such that the associated fan directs air in a first rotational direction along the inner wall of the base upon actuation. Filters may be situated at a bottom of each tube, as shown in FIG. 5. As an option, the tubes may be equipped with breathing apertures for communicating air with that circulated by the bottom fan.

The fan assembly further includes a plurality of circularly configured fans 26 each mounted to the top face of the cover and the inner wall of the base within the compartment. The fan assembly is adapted for directing air in the first rotational direction upon the actuation thereof. Furthermore, the fan assembly includes a cover fan 28 mounted in a recess formed adjacent an apex of the top face of the cover. The cover fan is adapted to circulate air between an interior and exterior of the compartment. A direction of air circulation afforded by the cover fan is preferably in tangential relationship with the cover. It should be noted that the fans situated within the cover remain in communication with the base via a pair of contacts situated on the upper and lower peripheral edges of the cover and base, respectively. Note FIG. 2.

Next provided is a heating assembly 30 mounted over the vents formed in the inner wall of the base. The heating assembly includes a pair of arcuate side conductors with a plurality of linear, laterally situated heating elements mounted therebetween for creating heat upon the actuation thereof.

FIGS. 3 & 4 show a rotisserie assembly 32 situated within the compartment and including an axle 34 rotatably mounted between central extents of the side faces of the base adjacent to the upper peripheral edge thereof. Two sets of radially extending arms 36 each have an inboard end coupled to a corresponding end of the axle and resides in a common plane. A pair of annular members 38 are each coupled to outboard ends of the radially extending arms of an associated one of the sets, thereby defining a ferris wheel-type mechanism.

For supporting food thereon, the rotisserie assembly includes a plurality of trays 40 each rotatably mounted between a pair of the radially extending arms. The rotisserie has a motor associated therewith for rotating the trays about the axle in a second rotational direction opposite the first rotational direction upon the actuation thereof. It should be noted that the trays may take any shape or form. In the preferred embodiment, a bottom of each tray is formed of a screen. As an option, an additional undulating screen may be removably situated on the bottom of each tray for supporting additional food products. As an option, open-sided trays may be employed.

Situated within the compartment is a thermostat 42 for detecting a temperature therein. As shown in FIG. 1, a control panel 44 is mounted on one of the side faces of the base with a display 46 for displaying a current temperature within the compartment. The display actuates the heating assembly and the motor of the rotisserie for a predetermined time period by means of a timer 48. Such time period may have any selected duration and further occur at any selected time. Such selection is preferably afforded by way of a key pad or the like. Such key pad may be employed for programmable heat control. The keypad preferably includes a plurality of preset buttons each of which corresponds to unique time and temperature for dehydrating jerky, pineapple, apples, oranges, banana, etc. When actuated, the heating assembly is governed so as to remain below a preset temperature. A temperature gauge(not shown) is preferably included for visually indicating the present temperature within the unit. For powering purposes, an alternating current cord and a battery back-up is provided. As such, optional AC/DC power is provided. In an alternate embodiment, solar energy may be employed.
