Egg Boiler Or Deep Fat Fryer Type Patents (Class 99/336)
  • Patent number: 5931081
    Abstract: The present invention features an electrical, frying appliance that uniformly cooks food items placed within its food basket. This frying appliance automatically immerses and extracts the cooking basket into and out of an aluminum oil bowl containing heated oil. In this fashion, the food in the basket is uniformly fried during the cooking cycle. The frying appliance contains a translationally movable basket that operates by a transmission wire driven by a shaft. The translational movement of the food basket allows the food in it to lie flat as it is immersed in the aluminum oil bowl. The food basket remains substantially horizontal during its movement between its immersed and non-immersed positions. In this fashion, the food items are prevented from shifting around in the frying basket. This allows the food to fry evenly within the basket and, when cycled, to be drained of oil periodically.
