Description

Technical Field

[0001] The present invention generally relates to an electric cooking appliance for cooking food, and more particularly to a teriyaki appliance. Background Art

[0002] In a known manner, a sizzling appliance comprises:

[0003] - a base configured to rest on a work surface,

[0004] - a bottom plate fastened to the base and configured to receive cooking vessels, each cooking vessel being designed to receive at least one food to be cooked,

[0005] a heating resistor disposed above the base plate and spaced apart from the base plate and configured to be at least partially located above the cooking vessel when the cooking vessel rests on the base plate, and

[0006] a cooking plate configured to at least partially cover the heating resistor, the cooking plate comprising a lower surface facing the base plate and an upper surface comprising a cooking surface configured to receive and heat food to be cooked.

[0007] In order to ensure optimal cooking of the food placed on the cooking surface on the one hand and melting of cheese contained in different cooking vessels on the other hand, grill appliances of the type mentioned above have a relatively high electrical power rating, usually above 800 W, and even above 1000 W for grill appliances whose base can accommodate eight cooking vessels simultaneously.

[0008] Therefore, since the food placed in the cooking container and on the cooking plate needs to be heated and / or cooked mainly by utilizing the heat radiation emitted by the heating resistor, the power consumption of such cooking appliances is relatively high. Summary of the Invention

[0009] The present invention aims to remedy these drawbacks.

[0010] The technical problem underlying the present invention is, inter alia, to provide a structurally simple and economical grill appliance which offers improved energy efficiency while maintaining satisfactory heating and cooking performances.

[0011] To this end, the present invention relates to a plate-fired utensil, comprising:

[0012] a base configured to receive cooking vessels, also called pots, each designed to receive at least one food to be cooked, such as a slice of cheese to be melted, or other food to be cooked (diced meat, sliced ​​onions or mushrooms, etc.);

[0013] a heating resistor arranged above the base plate and spaced apart from the base plate and configured to be at least partially located above the cooking vessel when the cooking vessel rests on the base plate, and

[0014] a cooking plate configured to at least partially cover the heating resistor, the cooking plate comprising a lower surface facing the base plate and an upper surface comprising a cooking surface configured to receive and heat food to be cooked, such as vegetables, pancakes or meat, such as bacon,

[0015] The lower surface of the cooking plate comprises a reflective surface having an emissivity between 0.60 and 0.80, advantageously between 0.65 and 0.80, even more advantageously between 0.70 and 0.75, for example approximately 0.73, the reflective surface being configured to reflect a portion of the thermal radiation emitted by the heating resistor towards the base plate and, therefore, towards the cooking vessel arranged on the base plate.

[0016] This configuration of the lower surface of the cooking plate allows a portion of the heat emitted by the heating resistor to be reflected towards the base plate and therefore towards the cooking vessel arranged on the base plate, thereby maintaining optimal cooking of the food contained in the cooking vessel, in particular ensuring the melting of the cheese contained in the cooking vessel, while reducing the electrical power of the heating resistor and therefore reducing the power consumption of the grill appliance.

[0017] Furthermore, this emissivity value of the reflective surface allows it to absorb the heat emitted by the heating resistor and thus store it, thereby ensuring satisfactory heating and cooking of food placed on the cooking surface provided on the cooking plate, such as bacon or vegetables.

[0018] The grilling appliance according to the invention thus ensures optimal cooking of food placed in various cooking containers and on cooking plates with simultaneously increased energy efficiency.
