Description
The present invention relates to cooking apparatus and more particularly to cooking apparatus that in some respects resembles the conventional sandwich toaster in which one or more sandwiches each consisting of two slices of bread with a filling between may be toasted between a pair of hingedly joined electrically heated plates.
The present invention may be regarded as an extension of the concept of the sandwich toaster for the production of a range of cooked foodstuffs such as hamburgers, fishburgers, eggs, bacon and toast, ham steak and toast, and other foodstuffs in which it is desired to cook a number of ingredients simultaneously the ingredients being such as to require the application of different degrees of heat in order to ensure that cooking of all ingredients is completed simultaneously.
In a preferred form of the invention described in detail below the apparatus is constructed to produce hamburgers by cooking simultaneously two halves of a burger bun, an egg and a burger pattie. The apparatus is constructed and arranged so that these four ingredients are cooked simultaneously. On completion of the cooking operation the ingredients are removed from the apparatus and assembled to form a hamburger.
The application of the invention is assisted by the fact that one cooking plate incorporates a sheet of transparent glass ceramic or other equivalent transparent material in which a heating element is incorporated. This not only enables the cooking of the ingredients to be watched but also, by reason of the low conductivity of glass ceramic facilitates the application of different degrees of heat to different ingredients.
", , According to the invention there is provided a cooking apparatus which includes a pair of hingedly connected cooking plates including a lower cooking plate incorporating a plurality of receptacles each for receiving a foodingredient to be cooked and an upper cooking plate including a transparent means for observing a degree of toasting of ingredients in the receptacles of the lower cooking plate. A first heating element is incorporated in the transparent means of the upper cooking plate to apply heat to an upper surface or surfaces of the ingredients to be cooked, parts of the first heating element being variably spaced apart to apply different cooking temperatures to different receptacles. A second heating element is incorporated in at least some of the receptacles of the lower cooking plate to apply heat to lower surfaces of ingredients contained in at least some receptacles. The first and second heating elements apply heat to all the surfaces simultaneously and complete cooking of all ingredients at a same time.
In order that the nature of the invention may be better understood a preferred form thereof is hereinafter described with reference to the accompanying drawings in which:-Figure 1 shows a cooking apparatus according to the invention intended for the preparation of hamburgers, the apparatus being shown with the cooking plates hinged apart, Figure 2 is a plan view of the cooking apparatus o~
Figure 1, Figure 3 is a transverse section on line III-III of Figure 2, Figure 4 is a cross sectional view on line IV-IV of Figure 2, Figure 5 is an exploded view of the arrangement of glass plates supporting the heating element seen in Figures 3 and 4, and Figure 6 is a view similar to Figure 5 showing an alternative arrangement in which the heating element is wound around a sheet of glass.
The cooking apparatus shown in the drawings is constructed in a manner very similar to a sandwich toaster -~" f and consists of a lower cooking plate 10 and an upper cooking plate 11 that are hingedly connected together by hinges 12.
Figure 1 shows the cooking plates in the open position; during a cooking operation the upper plate 11 is hinged down onto the lower plate 10 and the two interconnected by means o~ a catch 13 while cooking is taking place.
In the embodiment of the invention shown ~he lower lG cooking plate 10 has four receptacles 1~, i5, 16 and 17.
The receptacles 14 and 15 are shaped to con.ain one half each of a burger bun 18 and 19. The shape o~ the receptacles is best seen in Figures 3 and ~. .he receptacles 14 and 15 are not provided with any electrical heating element as burger buns are not normally toasted on the outside.
The receptacle 16 is designed for the receipt of an egg 21 and the receptacle 17 for receipt of a burger pattie 22. It is to be noted that the floor 23 of the receptacle 17 is sloping so that fat from the hamburger pattie flows to one side of the receptacle and out of the passage 24 from whish it can flow into the removable container 25. A thermostatically controlled relay 26 is provided on the underside of the receptacle 17.
Receptacles 16 and 17 are heated by means of the same calrod heater element 27. Somewhat less heat is provided to the receptacle 16 than to the receptacle 17 by the provision of cold pin connections at the two ends of the element 27 beneath the receptacle 16.
The upper cooking plate 11 consists of an outer frame 28 which is arranged to support three ceramic glass sheets 25, 30 and 31; between the latter two is arranged a heating element 32 consisting of nichrome wire supported on a mica armature 33. The nichrome wire heating element 32 consists of strips of wire arranged to extend -transversely across the sheets of ceramic glass 29, 30 and 31. It is to be noted that the spacing of the nichrome wires above the receptacles 16 and 17 is closer than above the receptacles 14 and 15 because more heat is required to cook the egg and the hamburger pattie than to cook the burger buns. A similar effect may be achieved by using nichrome wire of different gauges in the two par~s of the upper cooking plate. The edges of the ceramic glass sheets 29, 30 and 31 are sealed by means of the gasket 34 of food 0 grade high grade temperature moulded silicone rubber.
Figure 5 shows in more detail the arrangement of the glass sheets 2g, 30 and 31, the manner in which the heat element 32 is supported on the armature 33 and the manner in which connections are made to the heater element.
Figure 6 shows an alternative arrangement in which the heating element 32 is wound around the glass plate 30 thus dispensing with the armature 33. This construction may be found to have production and cost advantages over the construction shown in Figure 5.
In a further alternative form of construction, not illustrated ln the drawings, the heater element is printed onto one of the glass sheets in a manner well known in the art. At the present time however the cost of printing a heating element capable of handling the power required makes this form of construction more costly than either of those described above.
In use the various ingredients are placed in the appropriate receptacles and the upper cooking plate 11 is hinged down onto the lower cooking plate 10 and electrical power is supplied to the heating elements. The heating elements, that is to say, the calrod element and the nichrome wire element 32, are constructed and arranged so that heat is supplied to the four ingredients at such a rate that all four ingredients are cooked to a correct degree in the same time. Cooking of the ingredients may 2 ~ 9 ~
be observed through the transparent ceramic glass plates 29 and 31. After cooking is complete the apparatus is opened and the hamburger pattie 22 is placed on one of the burger buns 18 or 19, the egg 21 is then placed on the burger pattie and the other half burger bun placed on top to produce a traditional hamburger.
The invention may be applied to other embodiments constructed to cook other multi-ingredient products for example fishburgers, ham steak and toast, eggs bacon and toast. It may also be constructed for example as a bread toaster having two receptacles suitable for bread and two suitable for crumpets.
The embodiment of the invention described above is given by way of example only, the invention being capable 15 of application in a variety of other ways with~n the scope of the invention as defined in the succeeding claims.
