Abstract

A portable cooling and heating device for cooling and heating foods placed therein is provided including a housing having a bottom wall, a top, a front wall, a rear wall, and side walls. A heating element for heating the foods and a removable cooling element for cooling the foods are positioned in a support which is insertable into and removable from the housing for positioning both the heating element and the cooling element adjacent the food. The heating element being mounted in the support and the cooling element being supported by the support for maintaining an interior of the housing cool prior to heating of the food.

Claims

1. A portable cooling and heating device for cooling and heating foods placed therein comprising:

a housing having a bottom wall, a top wall, a front wall, a rear wall, and side walls;

a heating means for heating said foods;

a removable cooling means for cooling said foods; and

a positioning means insertable into said housing for positioning both said heating means and said cooling means adjacent said foods, said heating means being mounted in said positioning means and said cooling means being supported by said positioning means for maintaining an interior of said housing cool prior to heating of said foods.

2. The device as defined in claim 1, further comprising a rack supported within said housing for receiving at least one food receptacle.

3. The device as defined in claim 2, wherein said rack supports a plurality of food receptacles.

4. The device as defined in claim 1, wherein said positioning means is a drawer which is slidable into and out of an opening formed in said housing.

5. The device as defined in claim 4, wherein said opening is in said front wall.

6. The device as defined in claim 5, wherein said housing is divided into first and second compartments by a partition wall extending from said front wall to said rear wall.

7. The device as defined in claim 6, wherein said opening is in a lower portion of said front wall and said drawer extends into the first of said compartments.

8. The device as defined in claim 7, further comprising a rack supported within said first compartment for receiving at least one food receptacle.

9. The device as defined in claim 8, wherein said drawer is slidable into a position below said food receptacle within said first compartment.

10. The device as defined in claim 9, further comprising a plate supported within said housing and positioned between said drawer and said food receptacle, wherein said plate includes a plurality of perforations which allows steam to circulate within said first compartment.

11. The device as defined in claim 10, wherein said rack includes a plurality of perforations to further allow steam to circulate within said first compartment.

12. The device as defined in claim 4, wherein said heating means is an electrically insulated heating foil and is mounted on an inner surface of a bottom wall of said drawer.

13. The device as defined in claim 12, wherein said drawer includes a means for connecting said heating foil to a power source.

14. The device as defined in claim 13, wherein said means for connecting said heat foil to a power source includes said male plug which extends from a rear wall of said drawer and is accessible through an opening in said rear wall of said housing when said drawer is in a fully inserted position.

15. The device as defined in claim 4, wherein said cooling means is a freezable ice pack and is positioned in said drawer for maintaining the interior of said housing cool.

16. The device as defined in claim 15, wherein said ice pack is filled with water, with the water being selectively placed in said drawer for steam heating said food in said receptacles.

17. The device as defined in claim 5, wherein said top wall includes first and second sections hingedly connected to one another, said first section covering a top of said housing and said second section covering said front wall and said opening when said top wall is in a closed condition.

18. The device as defined in claim 17, wherein at least said first section include a smooth inner surface for forming a tabletop when said top wall is in an open condition.

19. The device as defined in claim 18, wherein said second section supports said first section in an essentially horizontal position when said top wall is in said open condition.

20. The device as defined in claim 17, wherein at least one of said sections includes a handle hingedly connected to an outer surface thereof.

21. A portable cooling and heating device for cooling and heating food contained in individual receptacles comprising;

a housing having a bottom wall, front wall, rear wall and side walls;

a top closure wall hingedly connected to said rear wall and pivotable between an open and closed position;

a drawer slidably insertable into a first opening in said housing;

a heating means mounted on a bottom wall of said drawer including a means for connecting said heating means to a power source, said means for connecting being accessible through a second opening in said housing;

a removable cooling means positioned within said drawer for maintaining the interior of said housing cool prior to the heating of said food; and

means for supporting said individual receptacles adjacent to said drawer within said housing.

22. A portable cooling and heating device for cooling and heating foods placed therein comprising;

a housing having a bottom wall, a front wall, a rear wall and side walls;

a top wall hingedly connected to one of said walls including a first section and a second section hingedly connected to one another, with said first section covering a top of said housing and said second section covering one of said walls and an opening in said one of said walls when said top wall is in a closed condition;

a cooling means for cooling an interior of said housing;

a heating means for heating said interior of said housing; and

a means for accommodating both said cooling means and said heating means;

wherein said means for accommodating both said cooling means and said heating means is slidable into and out of said opening formed in said housing.

23. The device as defined in claim 22, wherein at least said first section includes a smooth inner surface for forming a tabletop when said top wall is in an open condition.

24. The device as claimed in claim 23, wherein said second section supports said first section in an essentially horizontal position when said top wall is in said open condition.

25. The device as defined in claim 22, wherein at least one of said sections includes a handle hingedly connected to an outer surface thereof.
