Description

The invention relates to a mobile grill device with a housing and a grill support and heat source arranged therein.

Mobile grills for home use are well known in the art. They can be placed in a desired location, for example in the garden of the customer and are powered by coal, gas or electric heating. These devices typically have a heat source located below the food to be cooked. Burning the downflowing meat juices can cause harmful substances. Furthermore, sauces can not be made from the meat juice. Ultimately, these grills typically reach temperatures of a maximum of 500-600 ° C.

From the catering equipment are also known, with which meat at particularly high temperatures of over 800 ° C is grilled from above. However, these devices, called "salamanders," are large and typically integrated into a kitchen, making them unsuitable for home use.

The object of the invention is to provide a grill that transfers the benefits of high-performance grills used in the catering to portable grills for home use.

Against this background, the invention relates to a mobile griller with a housing and arranged therein grill support and heat source, wherein the heat source is disposed above the grill support, that the distance between the grill support in the heat source is adjustable and that the heat source for operation at temperatures of is designed above 500 ° C and preferably above 800 ° C.

According to the invention, a mobile and suitable for home use device is proposed, which makes use of the principle of extreme heat coming from above. Due to a burner temperature of over 800 ° C, the meat only has to be fried on each side for about 1 minute. The high heat creates a perfect crust and a variety of roasted aromas develop. Due to the top heat, the meat juice is not lost, but can drip into a dish under the grill to form a base for sauces.

In one embodiment, the grill top is a grill grate. In one embodiment, the grill grate may be removed from the housing, for example, for cleaning or maintenance.

In one embodiment, the heat source is a gas burner and preferably a ceramic gas burner. Such burners spend most of their energy in the form of infrared radiation. Preferably, the burner is configured to heat up to operating temperature within less than 3 minutes, and preferably less than 1 minute.
