ABSTRACT:
FIELD OF THE INVENTION
The present invention relates containers, more particularly, to a portable thermoelectric cooling and heating appliance device and associated method of using the device.
DESCRIPTION OF THE PRIOR ART
In today's modern times, the commuter times are getting longer, and various other automobile road trips are also getting longer. As a consequence, the motorist often finds a need for both heating food and chilling beverages within the automobile. A wide variety of portable thermoelectric cooling and heating appliance devices is currently available on the commercial market and an even larger number of these types of devices are known in the art of portable thermoelectric cooling and heating appliance devices, for example, the portable heating and cooling appliance disclosed by Munz and Collins in U.S. Pat. No. 3,111,166; the portable battery operated hot-cold storage unit disclosed by Pullens in U.S. Pat. No. 4,027,727; the vehicle thermoelectric cooling and heating food and drink appliance disclosed by Trachtenberg and Trachtenberg in U.S. Pat. No. 4,759,190; the portable beverage dispenser disclosed by Forrester in U.S. Pat. No. 4,913,318; the portable electric water heater for outdoor use disclosed by Alston and Cattron in U.S. Pat. No. 4,947,025; and the thermoelectric container disclosed by Kahl and Taylor in U.S. Pat. No. D350,048.
While all of the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a portable thermoelectric cooling and heating appliance device having a generally rectangular box, a hinge, a generally rectangular lid, a locking means, and a power cord, in which the box has a divider wall which defines a partition between a left and a right chamber within the box, wherein the box further includes: an outer shell; an insulation layer; a inner shell; a power input plug; a first heat transfer unit; a first network of cooling/heating coils; a first control knob having a first voltage regulator and a first thermostat operationally connected to each other; a first spigot having a first button and a first drain; a second heat transfer unit; a second network of cooling/heating coils; a second control knob

having a second voltage regulator and a second thermostat operationally connected to each other; and a second spigot having a second button and a second drain. This combination of elements would specifically match the user's particular individual needs of making it possible to to use the device in the method comprising the steps of adjoining, affixing, allowing, closing, disconnecting, grabbing, inserting, letting, lowering, obtaining, placing, positioning, pressing, pulling, pushing, raising, removing, setting, taking, turning, and unplugging. The above-described patents make no provision for a portable thermoelectric cooling and heating appliance device having a generally rectangular box, a hinge, a generally rectangular lid, a locking means, and a power cord, in which the box has a divider wall which defines a partition between a left and a right chamber within the box, wherein the box further includes: an outer shell; an insulation layer; a inner shell; a power input plug; a first heat transfer unit; a first network of cooling/heating coils; a first control knob having a first voltage regulator and a first thermostat operationally connected to each other; a first spigot having a first button and a first drain; a second heat transfer unit; a second network of cooling/heating coils; a second control knob

having a second voltage regulator and a second thermostat operationally connected to each other; and a second spigot having a second button and a second drain.
Therefore, a need exists for a new and improved portable thermoelectric cooling and heating appliance device having a generally rectangular box, a hinge, a generally rectangular lid, a locking means, and a power cord, in which the box has a divider wall which defines a partition between a left and a right chamber within the box, wherein the box further includes: an outer shell; an insulation layer; a inner shell; a power input plug; a first heat transfer unit; a first network of cooling/heating coils; a first control knob having a first voltage regulator and a first thermostat operationally connected to each other; a first spigot having a first button and a first drain; a second heat transfer unit; a second network of cooling/heating coils; a second control knob
28
having a second voltage regulator and a second thermostat operationally connected to each other; and a second spigot having a second button and a second drain. In this respect, the portable thermoelectric cooling and heating appliance device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing a means for making it possible to use the device in the method comprising the steps of adjoining, affixing, allowing, closing, disconnecting, grabbing, inserting, letting, lowering, obtaining, placing, positioning, pressing, pulling, pushing, raising, removing, setting, taking, turning, and unplugging.
SUMMARY OF THE INVENTION
The present device and method of using, according to the principles of the present invention, overcomes the shortcomings of the prior art by providing a portable thermoelectric cooling and heating appliance device and method of using are disclosed. The device comprises: a generally rectangular box, a hinge, a generally rectangular lid, a locking means, and a power cord. The box has a divider wall which defines a partition between a left and a right chamber within the box. The box further includes: an outer shell; an insulation layer; a inner shell; a power input plug; a first heat transfer unit; a first network of cooling/heating coils; a first control knob having a first voltage regulator and a first thermostat operationally connected to each other; a first spigot having a first button and a first drain; a second heat transfer unit; a second network of cooling/heating coils; a second control knob having a second voltage regulator and a second thermostat operationally connected to each other; and a second spigot having a second button and a second drain. The hinge is attached to the outer shell of the box. The lid is dimensioned to substantially fit over the top of the box, in which the lid is attached to the hinge, whereby the lid is pivotally attached to the box. The locking means is for locking together the lid to the box, in which a first portion of the locking means is attached to the box, and a second portion of the locking means is attached to the lid. The power cord has a first socket end and a second socket end, in which the first socket end is operationally connectable to the power inlet plug of the box, and the second socket end is operationally connectable to a standard cigarette lighter power output in an automobile. The method of using the device comprises the steps of adjoining, affixing, allowing, closing, disconnecting, grabbing, inserting, letting, lowering, obtaining, placing, positioning, pressing, pulling, pushing, raising, removing, setting, taking, turning, and unplugging.
In view of the foregoing disadvantages inherent in the known type portable thermoelectric cooling and heating appliance devices now present in the prior art, the present invention provides an improved portable thermoelectric cooling and heating appliance device, which will be described subsequently in great detail, is to provide a new and improved portable thermoelectric cooling and heating appliance device which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
To attain this, the present invention essentially comprises a generally rectangular box, a hinge, a generally rectangular lid, a locking means, and a power cord. The box has a divider wall which defines a partition between a left and a rig
