The present invention concerns a universal steam cooker for use in a microwave. This cooker may be used to cook a variety of foodstuffs via microwave energy.
U.S. Pat. No. 4,923,704 describes a kit cooking food in a microwave, and utilizes various elements to perform the cooking.
U.S. Pat. Nos. Des. 258,106 and Des. 339,713 show hot dog steamers.
According to the present invention, a microwave cooking device, for cooking elongated foods is provided which includes three members:
a lid for covering the food to be cooked;
a base member for holding a microwavable, steam producing liquid; and
a tray member for holding or supporting the food to be cooked.
Said elements fitting together so that the food to be cooked is placed on the tray, the tray is placed on the base above the liquid, the lid is placed on the base covering the food and tray, and the entire unit placed in a conventional microwave oven.
FIG. 1 is a frontal view of the steam cooker;
FIG. 2 is a side view of the steam cooker;
FIG. 3 is a perspective view showing the lid used in the cooker;
FIG. 4 is a perspective view showing the base unit of the cooker;
FIG. 5 is a perspective view showing a cooking tray; and
FIG. 6 is a perspective view showing a second cooking tray.
Referring to FIG. 1, reference number 1 indicates the steam cooker as a unit. The steam cooker is comprised of various components and will be more fully described hereinafter.
The steam cooker includes a lid 2, a base 3, and a tray 4. The lid 2 (FIG.3) includes a top portion 5, two end walls 6, 7, two side walls 8, 9, and two handles 11 and 12 attached to end walls 6, and 7 respectively. The top portion 5 includes a series of apertures 5A through which steam may pass.
The base 4 (FIG. 4) includes a bottom portion 13, two end walls 14, 15; two side walls 16, 17 and two handles 18, 19 attached to end walls 14, 15 respectively.
The bottom portion 13 is connected to the end walls 14, 15 and the side walls 16, 17 so as to form an open container having a cavity 20. The cavity 20 is formed for the purpose of holding liquid 27 to produce the steam for the cooker. The cavity is made up of an upper and lower portion. The lower portion being smaller than the upper portion and formed by the bottom portion 13 and parts 14A and 15A of base end walls 14, 15 and parts 16A, and 17A of base side walls 16, 17. The upper portion of the cavity 20 is formed by parts 14B and 15B of base end walls 14, 15 and parts 16B and 17B of base walls 16, 17, and located immediately adjacent the lower portion. Each base end wall 14 and 15 and each base side wall 16 and 17 include a step portion 14c, 15c, 16c and 17c, respectively. The step portions are formed between the respective parts 14A , 15A, 16A, 17A and parts 14B, 15B , 16B, 17B and support the tray 4 of the cooker. The tray can be made of various designs and is utilized to support the food stuff that is being steam cooked.
The tray 4 (FIG. 5) comprises a base support member 21 and food support members 22. The parallel food support members 22 are located on the base support member such that they extend perpendicular to the member 21. The base support member 21 also includes a series of apertures 23 extending entirely through the base support member. The apertures 23 allow for steam to pass through the tray, past the food stuff and out the apertures 5A in the lid 2.
The tray 4 is designed to fit into the upper portion of the cavity 20 and to contact the steps 14C, 15C, 16C, 17C and be supported thereby. Once the tray 4 is in place the lid 2 is then placed onto the base 3 covering the tray. End and side walls 6, 7, 8, 9 of the lid contact and are supported by end and side walls 14, 15, 16 and 17 of the base.
FIG. 6 shows another tray 4 comprised of a base support portion 24, a food support means 25 and a series of apertures 26 running through the tray from the food support means 25 to the base support portion 24. The food support means 25 is made up of a plurality of concave arcuate grooves formed in the tray 4. The arcuate grooves support food items directly therein and run parallel to the base support portion and to each other. The concave arcuate grooves substantially cover the entire surface of the tray 4.
In use, the user begins by removing the lid 2 and tray 4 from the base 3. Then a steam producing liquid 27, most commonly water, is placed in the lower portion of the base cavity 20 and food items, to be steam cooked, are placed on the tray 4. Once that is done the tray 4 is placed on the base 3 at the steps 14C, 15C, 16C, 17C, and then the lid is placed onto the base, over the tray 4 and food items. The entire unit is then placed in a conventional microwave oven. The microwave is activated and the liquid 27 is heated. As the liquid 27 is heated, steam is produced and the steam passes through the tray 4 by means of the apertures 23. After the steam passes through the tray, it passes over the food, thus steam cooking it, and passes out through the lid 2 by means of the apertures 5A.
This steam cooker can be used to cook a wide variety and sizes of foods with the main direction toward hot dogs, sausages, kielbasy and other elongated foods. Further the tray shown in FIG. 6 is intended to steam cook stuffed foods such as cheese hot dogs. The unit can be made of a wide variety of microwavable safe materials, known by those skilled in the art, such as plastic, glass, ceramic, etc.
