Definitions

  • the field of the invention relates to food preparation and more particularly to methods of frying food.
  • Devices for deep frying foods are well known. Such devices typically include a bowl of oil with a heater immersed in the oil or connected to a bottom of the bowl. A thermometer may be provided as an indicator of the temperature of the oil.
  • a basket is provided that fits inside the bowl of oil. Typically food is placed within the basket and then lowered into the hot oil for cooking.
  • a timer may be provided to indicate completion of the cooking cycle. Once the cooking cycle is complete, the basket may be raised and secured to the edge of the bowl in order to allow excess oil to drain back into the bowl.
  • the oil in which the food is cooked is a known health risk, both from the fat and debris within the oil.
  • the oil remains in the bowl for an extended period of time, going through a number of cooking cycles.
  • debris accumulates in the oil.
  • the debris may degrade over time, resulting in carbonization of the debris and the accumulation of potential carcinogens within the oil.
  • the degraded debris may remain in the oil or some portion of the oil may adhere to the cooked food at the completion of the cooking cycle.
  • newer deep fryers sometimes provide a mechanism for spinning the basket after cooking to remove excess oil, these devices often present a health risk to the cook from splattered oil. Accordingly, a need exists for better methods of protecting both the cook and consumer of food from risks associated with such devices.

  • the device 10 may be constructed with only a single cooking bowl. While the description provided below will be directed to operation of only a single bowl, it should be understood that the second bowl would operate in substantially the same manner.
  • two frying bowls 12, 14 are provided, it is intended that the two frying bowls 12, 14 of the figures may be used simultaneously. Alternatively, the two frying bowls 12, 14 allow for continuous use of the device 10 by allowing one of the two frying bowls 12, 14 to be shut down for cleaning while the other is in use.
  • two frying bowls 12, 14 provides a number of advantages when used simultaneously.
  • one bowl 12, 14 may be used for frying one food (e.g., fish) while the other bowl 12, 14 is used for frying a different food (e.g., chicken).
  • the processing of the oil 16 in the two frying bows 12, 14 is completely separate and allows the oil 16 that is used to fry fish to be handled and filtered separately from the oil 16 that fries chicken thereby preventing cross-contamination of the oils 16.
  • each of the bowls 12, 14 is a frying basket 30 (FIG. 4). Also included within each frying bowl 12, 14 is a submersible heater 34 such as that shown in FIG. 6. As shown in FIG. 6, the heater 34 is hinged to a housing of the device 10 along the edge of the housing of the device 10. In a first position, the heating element of the heater 34 is located in a normal position at a bottom of the bowl 12, 14. However, the heater 34 may be rotated upwards and out of the bowel 12, 14. This configured allows debris to be easily removed from the bowl 12, 14 once the bowl 12, 14 is drained as described below.
  • FIG. 12 depicts details of the basket 30 and a set of detachable handles 68.
  • each of the basket handles 68 includes a set of set of wire clips 70 that engage a lower portion of an upper flange 74 of the basket 30.
  • a thumb paddle 72 allows a user to twist the handle 68 into positive engagement with the flange 74.
  • the use of the handles 68 give the user exceptional control over a hot basket 30 when dumping large quantities of food.
  • the detachable handles 68 allow for use of left or right handles for right or left handled people.
  • the basket 30 has an 8 pound frying capacity and allows for the use of both handles 68.
  • Each bowl 12, 14 may also include a lid 32.
  • the lid 32 may be made of a transparent material that allows a user to observe the cooking process without removal of the lid 32.
  • FIGs. 13 and 14 show further details of the lid 32.
  • the lid 32 may include one or more notches 76 that allow the lid 32 to be closed around the handles 68 and held in a closed position by a latch.
  • a rubber flap 78 extending partially around the notches 76 substantially seals the lid 32 to the housing of the device 10 and reduces splatter of hot oil from the bowl 12, 14.
  • a release pushbutton 84 may be used to release the lid 32.
  • An interlock associated with the latch may be used to disable device 10 until the lid 32 is closed.
  • the lid 32 may include a spring 80 that reduces the effort required to lift the lid 32 to an upright position. Once raised to an upright position, a tab 82 prevents the lid from falling backwards away from the vertical. As shown in FIG. 14, a counterweight 86 may be used to assist lifting the lid 32.
  • the spin motor 36 may be a stepper motor or a direct current (DC) motor with encoder feedback. As shown in FIG. 7 A, the spin motor 36 may be coupled to the basket 30 via a belt 38 and drive shaft 42 extending through the bottom of the bowl 12, 14. A spline 40 on the upper end of the drive shaft 42 couples the drive shaft 42 to a splined hole inside a hub of the basket 30.
  • the device 10 drains the hot oil 16 from the bowl 12, 14 at the end of each cooking cycle. This has significant advantages both in terms of safety and also because it allows the oil 16 to be filtered at the end of each cooldng cycle.
  • the filling of the bowl 12, 14 with hot oil at the beginning a cooking cycle and draining of the oil from the bowl 12, 14 at the end of the cooking cycle ensures that the user is never exposed to the danger of hot oil.
  • the draining of the oil after each cooking cycle allows the oil to be filtered after each cooking cycle.
  • the cycling of the oil from the frying bowl 12, 14 to a reservoir through a filter allows for the constant filtration of the oil for prolonged oil life and enhanced food flavor.

The divider 44 contacts the food during rotation causing the food to rotate 46 with the basket 30. The rotation of the food with the basket 30 reduces the effect of temperature differences within the oil 16 and produces a more even cooking of the food 48 within the basket 30.
