DETAILED DESCRIPTION OF PREFERRED BEST MOLDS
Referring to FIGS. 2 to 5, the present invention provides an electromagnetic induction heating grill toaster 1 that includes a first casing body 2, a first baking tray 3, a second casing body 4, and a second baking tray 5. The first casing body 2 has a first electromagnetic induction element 21, a first micro-crystal plate 22, and a control element 23. The control element 23 is disposed on an inner bottom portion of the first casing body 2. The first micro-crystal plate 22 is disposed on a top portion of the first casing body 2. The first electromagnetic induction element 21 is electrically connected with the control element 23. The first electromagnetic induction element 21 is an electromagnetic coil for inducting magnetic materials with iron. Electric currents of the electromagnetic coil generate magnetic flux variations, so that eddy currents are generated in the casing body to directly heat the micro-crystal plate so as to cook food. The control element 23 controls the whole system of the present invention.
The first casing body 2 has two fixed portions 24 and a first handle 25 all disposed on a bottom side thereof. The electromagnetic induction heating grill toaster 1 further includes an operation panel 26 installed on the first casing body 26 for setting cooking (grill and toast) time and temperature, etc. The first casing body 2 has a plurality of first concave grooves 27 respectively formed on two sides thereof for fixing the first baking tray 3 in place. Hence, the first baking tray 3 is detachably disposed on the first casing body 2. The first baking tray 3 is made of magnetic complex materials with iron, such as complex metals or stainless steel, etc. The electromagnetic induction heating grill toaster 1 further includes a heat-dissipating fan 28 disposed in the first casing body 2 for dissipating heat from the control element 23. In addition, the electromagnetic induction heating grill toaster 1 further includes a temperature-controlling element 7 disposed on the first casing body 2.
The second casing body 4 has one side pivoted on one side of the first casing body 2. The second casing body 4 has a second electromagnetic induction element 41 and a second micro-crystal plate 42.
