  • water is retained in the compartment of the base member and the heater is energized by the switch for heating the water to generate steam.
  • a plurality of food retaining members having porous food supporting surfaces are provided for use in supporting food to be dehydrated, and these members are vertically stackable on each other with the porous food supporting surface of each of the food retaining members being vertically spaced from the porous food supporting surface of an adjacent food retaining member.
  • a separate support member is retainable in the compartment of the base member under the food retaining member that is utilized to support food for steaming.
  • the support member includes a collection trough for collecting condensate generated during the steaming of foods.
  • a food retaining member utilized during the steaming operation includes a bottom wall for retaining food to be steamed thereon, said bottom wall including a first liquid-impervious section for retaining condensate thereon and a second section at which condensate can leave said food retaining member.
  • a separate support member is retainable in the compartment of the base member under the food retaining member that is utilized to support food for steaming, and that support member includes a collection trough for collecting condensate that leaves the food retaining member at the second section of the bottom wall.
  • the bottom wall of the food retaining member employed to retain food during the steaming operation includes passages through which condensate generated in the steaming operation can exit the retaining member.
  • the base member includes an inner wall defining a compartment for retaining water during the steaming operation, a passage extending through the inner wall, a heater, and a fan means for directing air into close proximity to the heater and through said passage into the food-steaming and food-dehydrating chamber of the device when the fan means is energized during the food-dehydrating mode of operation of the cooker.
  • the base member of the cooker includes a switch having a first position for energizing both said fan means and said heater for dehydrating food, and a second position for energizing said heater without energizing said fan means to steam food.
  • a closure member is provided for closing the opening into the passage extending through the inner wall of the base member when food is being steamed to prevent condensate generated during the steaming operation from entering the passage and possibly damaging the heater and/or fan.
  • the closure is part of a support member that also is employed to support the food retaining member utilized to support food during the steaming operation.
  • a number of different food retaining members can be provided for use in retaining food during the steaming and/or dehydrating operations.
  • a conventional pan having a bottom wall that is completely impervious to liquids can be employed for steaming a variety of food items, both liquid and solid.
  • a retaining member can be provided including a plurality of spaced, egg-supporting members on a surface thereof.

  • Fig. 8 is an isometric view of an alternate design for a supporting member utilized in the steaming mode of operation of the cooker of this invention.
  • Fig. 9 is a schematic view of a circuit utilized in the present invention.
  • a multi-purpose cooker embodying the present invention is generally shown at 10 in Fig. 1.
  • the device 10 basically comprises a base member 12 and a cover member 14 defining an internal chamber 16 in which a number of food retaining members and a support member are retained. Details relating to these food retaining members and the support member will be described later herein. Suffice it to state for the present, the cooker shown in Fig. 1 includes all of the components which are utilizable for either steaming or dehydrating foods, and all of these components are easily assembled within the chamber 16 for storage or shipment of the cooker 10.
  • the base member 12 includes an inner wall 18 defining a compartment 20 therein.
  • a heater 22 includes a conductive plate 23 forming part of the inner wall 18, and this conductive plate includes a central passage 24 therethrough. This passage 24 communicates with the chamber 16 through a cylindrical chimney 26 extending upwardly from the conductive plate 23 of the heater 22.
  • the heater 22 is of a conventional design including encapsulated heating coils 25 (Fig. 3) on the lower surface of said conductive plate.
  • a support member 28 includes four downwardly extending projections, or legs, 30 (only one of which is illustrated in Fig. 2) spaced about the circumference thereof and being seated on the inner wall 18 of the base member 12.
  • This support member 28 includes a peripheral wall 32 with a plurality of circumferentially spaced-apart, upstanding lugs 34 integrally molded therewith.
  • a pair of arms 36 and 38 cross each other in the interior region bound by the peripheral wall 32, and these arms include a downwardly facing cylindrical closure, or hub, 40 at their crossing location.
  • the hub 40 of the support member 28 seats over the cylindrical chimney 26 to close the passage 24 formed through the heater 22, and the upstanding lugs 34 of the support member support, and assist in positioning, food retaining members employed to retain food to be steamed, as will be described in greater detail hereinafter.
  • each of the food retaining members 42 includes an upper, porous wall 44 for supporting food to be dehydrated in the cooker 10 and downwardly projecting legs 46 circumferentially spaced apart about the periphery of the wall 44.
  • the legs 46 in the packaged or stored condition of the cooker 10, straddle the peripheral wall 32 of the support member 28, and the lower surface of the upper wall 44 of the lowermost member 42 engages the upper surfaces of the upstanding lugs 34.
  • two food retaining members 48 and 50 which are particularly suited for use in supporting food to be steamed in the cooker 10, are stacked on top of the nested food retaining members 42.
  • the diameter of the food retaining member 50 is sufficiently smaller than the diameter of the food retaining member 48 to permit the member 50 to seat within the member 48 when the unit is packaged for shipment or storage. It should be understood that in accordance with the broadest aspects of this invention it is not required to form the food retaining members 48 and 50 of different sizes. Moreover, it is also within the scope of this invention to form the member 48 of a smaller diameter than the member 50, to permit the member 48 to be stacked within the member 50. In this latter case the food retaining member 50 will be the member supported on the stacked food retaining members 42.
  • the cover member 14 includes vent passages extending through the upper wall thereof.
  • the cover includes two sets 15 and 17 of vent passages. These vent passages prevent the undesired build up of pressure within the cooker 10.
  • each of the vertically stackable food retaining members 42 is employed to support food to be dehydrated, e.g., fruits, vegetables, and the like. Most preferably a plurality of the retaining members 42 are employed in a non-nested condition to support the food on different vertical tiers, as is shown in Fig. 3. Specifically, each of the food retaining members 42 is positioned relative to its immediately underlying member 42 such that the legs 46 of the upper member rest on the porous food supporting upper wall 44 of the underlying member.
  • each of the food retaining members 42 includes circumferentially spaced-apart, enlarged openings 52 (Fig. 2) extending through it for receiving the legs 46 of the immediately overlying food retaining member 42 therethrough when it is desired to collapse, or nest, the plurality of food retaining members 42.
  • This is a conventional and well-known design feature.
  • the base member 12 includes an outer base wall 54 spaced from the inner wall 18 to define a space 56 therebetween in which a fan assembly 58 is housed.
  • the fan assembly 58 includes a mounting plate 60 having a motor 62 attached thereto by screws or other suitable fasteners, an aperture 64 extending through the mounting plate 60 in alignment with the driven output shaft 66 of the motor, and an impeller 68 disposed on the side of the mounting plate opposite the motor and connected to the output shaft 66 of said motor. Therefore, when the motor 62 is energized to rotate the output shaft 66 thereof, the impeller will be rotated to generate air flow.
  • the air flow generated by the rotating impeller is directed through a confining channel 70 that communicates the impeller with an air outlet port 72 in the mounting plate 60.
  • the channel 70 is provided by the cooperation of a generally cup- shaped segment 71 of the outer base wall 54 with the mounting plate 60 of the fan assembly 58.
  • a conical air-guiding member 74 is secured to the mounting plate 60 by any conventional means, such as by welding.
  • This air-guiding member 74 has a central passage 76 aligned with the outlet port 72 in the mounting plate and with the central passage 24 through the conductive plate member 23 of the heater 22 to guide the air generated by the rotating impeller 68 into close proximity with the encapsulated heating coils 25 of the heater 22 for heating the air.
  • the heated air which is essentially dry, then is directed through the passage 24, the chimney 26, and into the internal chamber 16 for contacting the food supported on the porous food supporting wall 44 of the food retaining member(s) 42 to dehydrate said food.
  • the switch 78 when the cooker 10 is to be used in the dydrating mode, the switch 78 is moved to the left as viewed in Fig. 1 and as is schematically indicated by arrow 79 in Fig. 9. In this condition the switch provides a single- contact switch action, and remains closed until it is moved back to its center "off" position.
  • the switch 78 When the switch 78 is in its closed condition, power is supplied through circuitry in latching relay 85, with the latching relay in its off condition, to power the heater 22 through thermostat 92, the motor 62 of the fan assembly 8, and the indicator light 80.
  • relay switch R3 in the "off" condition of relay 85, relay switch R3 is closed and relay switches Rl and R2 are open, as shown in solid line representation in Fig. 9.
  • this member 48 employs the food retaining member 48 to support the food to be steamed.
  • this member 48 has a bottom wall 82 having a central, liquid-impervious section 84 for supporting the food and for precluding any condensate formed thereon during the steaming operation from passing therethrough.
  • the bottom wall 82 includes a peripheral section 86 including a plurality of circumferentially spaced-apart passages 88 through which condensate collected in the food retaining member 48 can pass. To direct the condensate to the peripheral section 86 so that the condensate can exit the member 48 through the passages 88, the bottom wall 82 is sloped slightly downwardly from the center thereof to the outer periphery thereof.
  • the support member 28 is employed to cover the central passage 24 through the conductive plate member 23 of the heater 22 to preclude liquid from entering the region 56 housing the fan motor 62 and the wiring thereto.
  • the support member 28 functions to support the food retaining member 48 so that the bottom wall 82 thereof is disposed above the distal edge of the cylindrical chimney 26, and to properly position the member 48 within the internal chamber 16 of the cooker 10.
  • the bottom wall 82 of the food retaining member 48 includes a short, downwardly extending annular flange 90 which has a diameter slightly less than the diameter of the peripheral wall 32 of the support member 28.
  • This arrangement positions the lugs 34, which are integrally formed extensions of the peripheral wall 32, around and in close proximity to the downwardly extending annular flange 90 to aid properly positioning the food retaining member 48 within the internal chamber 16 of the cooker.
  • This same cooperative arrangement exists between a downwardly extending flange (not shown) on the bottom wall of the food retaining member 50 and the lugs 34 of the support member 28. It should be understood that in steaming some foods, and in particular solid foods, condensate will form on the food being steamed and drip onto the food supporting surface of the food retaining member.
  • a food retaining member which permits the condensate to escape from, or leave, the food retaining member, such as the food retaining member 48.
  • the food retaining member should be free of liquid-pervious surfaces through which the liquid to be cooked can escape.
  • a food retaining member of the type illustrated at 50 is most desirable.
  • the switch 78 To operate the cooker 10 in the steaming mode, the switch 78 is moved to the right, as viewed in Fig. 1 and as is schematically indicated by arrow 81 in Fig. 9. In this mode of operation the switch 78 functions as a momentary switch, and, after initially closing the circuit, automatically returns to an open switch position.
  • the relay 85 closes to energize the coil and latch the rely down. This opens relay switch R3 and closes relay switches Rl and R2, as shown in dotted lines in Fig. 9, to remove the motor 62 from the circuit and complete the circuit to the thermostat 92, heater 22 and indicator light 83. Power to the relay coil is then derived from the thermostat 92, to maintain the relay in its latched condition.
  • the heater 22 functions to boil the water 11 to steam, until such time as the compartment either is almost dry (e.g., 20% of the water remains) or is completely dry, depending on the operating specifications of the thermostat 92.
  • the thermostat 92 reaches a predetermined high temperature level, as determined by its operating specifications, it opens to shut off the heater 22, and also drop (i.e., unlatch) the relay 85 out of the circuit to open contacts Rl and R2, and close contact R3 of the relay 85. This prevents the relay 85 from reclosing (i.e., becoming latched) when the thermostat 92 recloses during cool down of the cooker 10.
  • the heater 22 will not be reenergized during cool down of the cooker.
  • the switch 78 can be designed solely as a single contact switch for use only in energizing the cooker 10 when it is to be operated in its dehydrating mode.
