Description

Technical Field

[0001] The utility model relates to the field of exhaust equipment, in particular to a novel plastic smokeless grill pan fan. Background Art

[0002] The electric grill pan is a device with a cooking plate and a heater in a base. The heater is powered on to cook meat, fish, shellfish, vegetables and other ingredients on the grill pan. However, the electric grill pan generates oil smoke during the cooking process. The existing method of removing oil smoke from the electric grill pan is to set a fan on one side of the electric grill pan. The fan rotates to form an air flow in the electric grill pan. The oil smoke is not discharged to the outside but is oxidized by hot air inside. However, the hot air oxidation of the oil smoke inside cannot really purify the oil smoke, which is easy to pollute the environment.

[0003] For example, the Chinese utility model patent with application number: 2022229017392, the invention is named a new type of smokeless grill pan, which discloses: "comprising a base, a grill pan and a heating element, the grill pan and the heating element are arranged on the base, and also comprising an air inlet cover, the base is provided with a receiving groove on one side of the grill pan, the air inlet cover is arranged on the receiving groove, the air inlet cover is provided with an air inlet, the base and the air inlet cover are provided with a smoke exhaust duct, the base is provided with an air outlet, the smoke exhaust duct connects the air inlet and the air outlet, and an electrostatic net, oil fume filter cotton and a range hood fan are arranged in the smoke exhaust duct". In the above technology, the range hood fan and the smoke exhaust duct are made into a whole, although Although this saves some parts costs, after years of work, a lot of oil will adhere to the range fumes fan, especially the fan blades on the range fumes fan are the hardest hit areas for oil adhesion, which will not only affect the normal operation of the range fumes fan, but also breed various bacteria to contaminate the food in the baking tray. In order to ensure the normal operation of the range fumes fan and prevent the breeding of a large number of bacteria, the range fumes fan needs to work regularly. In the above technology, the range fumes fan is integrated into the exhaust duct. In this way, when cleaning the range fumes fan, the exhaust duct must also be disassembled and the range fumes fan must be removed from the exhaust duct before cleaning the range fumes fan. This will cause a lot of workload and low work efficiency. Utility Model Content
