Description

GAS GRIDLE

The present invention relates to a gas griddle used for cooking iron plate food in a kitchen, and performs uniform heat transfer to an iron plate used as a cooking plate to increase thermal efficiency while preventing deformation and damage caused by thermal stress of the iron plate, It also relates to a gas griddle capable of protecting a cooking worker from cooking fumes generated during the cooking operation of an iron plate.

In general, a gas griddle apparatus is to install a burner at the bottom of a cooking plate to cook meat, vegetables, etc. on the cooking plate, and is used in large restaurants or food service centers.

Each burner provided in such a gas grid includes a separate ignition device for ignition. Such a conventional gas griddle apparatus uses a Bunsen type burner combustion method.

The above-mentioned Bunsen type burner combustion method is a method in which the air required for combustion is properly decomposed and supplied over the primary and secondary stages. The conventional gas griddle apparatus using the Bunsen type burner combustion method has a problem in that the temperature of the cooking plate is not uniform due to its structure.

In addition, since convective heat is used, heat transfer is not easy to the edge portion, and heat is concentrated in the portion where heat is applied, resulting in bending of the iron plate used as the cooking plate.

On the other hand, cooking fume or cooking oil fume generally refers to visible emissions generated when frying with oil. It is defined as solid particles.

The health hazards of cooking workers in the cooking industry such as the food and beverage industry are irritants from cooking fumes, allergens, polycyclic aromatic hydrocarbons, noise, smoke, extreme temperatures, congestion, stress, electromagnetic waves, etc. , dermatitis, asthma, low back pain and musculoskeletal disorders such as work-related upper extremity disorders, psychosocial disorders, and oral and laryngeal cancers are increasing.

Accordingly, in the trend of increasing stir-frying and meat-grilling dishes using an iron plate such as a griddle, cooking fumes generated during iron plate cooking are highly likely to harm the health of cooks who cook for a long time.

Meanwhile, for prior art documents related to gas grids, reference may be made to 'gas grid apparatus' disclosed in Korean Patent Publication No. 10-2011-0032119, 'gas griddle' disclosed in Korean Patent Registration No. 10-1823097, and the like. have.
