Description

Electric heating smokeless grill

Technical field

The invention relates to an electric heating grill, in particular to an electric heating infrared grill.

Background technique

The electric heating infrared grill is a kind of infrared light generated by heating by the electric heating tube penetrates into the food, so that the energy of the molecules or atoms of the food absorbs the infrared rays to generate strong vibration, so that the temperature of the food rises, thereby achieving the purpose of heating. Compared with the traditional carbon-baked oven, the infrared oven is more and more widely used in people's daily life because it does not require fire, penetration, uniform heating and simple use.

The structure of the traditional electric heating infrared grill is to place a heating tube in the lower part of the furnace body, a barbecue net is placed on the upper part of the furnace body, and the food is placed on the barbecue net for heating and grilling. Although the infrared grilling has many advantages over the traditional grilling, the oil and fat in the grilling process will drip in the high temperature furnace body or the heating body to vaporize and decompose to generate a large amount of oil smoke, which not only affects the interest of people gathering barbecue, but more importantly, it will Human health and the environment cause great harm. In order to avoid the above situation, the grease is separated from the heat source, and people think of a variety of ways, such as converting the heating device from below to hanging over the food, or using a vertical grilling method, the heating tube is placed vertically, and the food is first stringed up. Then hanging around the heating tube for barbecue, although the problem of soot can be avoided to a certain extent, but the operation process of the barbecue is very inconvenient, and the barbecue method is not in line with the traditional barbecue habit of the public.

On the other hand, the cleaning problem after the use of the traditional infrared grill has been plagued by the fact that, due to the continuous dripping of grease during the grilling process, a large amount of grease or char is accumulated in the furnace, which is very difficult to clean. The cleaning of the whole machine is not only inconvenient, but also has potential safety hazards. If you do not pay attention to the wetness of the electrical parts, there is a danger of leakage. To avoid dripping grease in the furnace The problem of cleaning inconvenience is caused by the merchants suggesting that the paper should be placed under the food during the barbecue. When the paper is infiltrated, the new paper is replaced. Obviously, this method is not only cumbersome, but also affects the barbecue, and the grease or The accumulation of water in the food on the paper will greatly affect the taste of the food being grilled.

Summary of the invention
