Description

A PORTABLE COOKING DEVICE

Field of the Invention

The present invention relates to a portable cooking device, more particularly but not exclusively a portable cooking device for use outdoors.

Background

It is often desirable to be able to cook outdoors, for example if camping or to be able to enjoy good weather in a garden. Typically a barbeque arrangement is provided wherein food is cooked over heated means, such as charcoal or gas burning elements. However, it can be difficult to regulate temperature on the barbeque and therefore it is common for food to cook quickly on the outside but not be fully cooked on the inside. Therefore food is often regularly moved during cooking to ensure full cooking of food, in particular meats such as chicken that may be detrimental for health if not fully cooked. This requires a user to be on hand at all times to monitor the food cooking which may be undesirable if entertaining guests or wanting to socialise with others during cooking.

Furthermore whilst cooking on the barbeque it is common for food residues such as fat to drip onto the heating means resulting in production of flames, or fire storms, and an increase in smoke which factors are undesirable during cooking both for quality of cooking and cooking experience. Whilst in some situations it may be possible to close a barbeque to improve the cooking experience it is then difficult to observe and harder to monitor cooking quality in addition or the alternative.
