- the act of securing the Hd onto the container causes the drive member 160 to be urged downwardly and the first 182 and second 190 clutch parts to be rotatably locked together as shown in Fig. 13.
- the condensate collector 90 is positioned in the base receptacle 40 as shown in Fig. 6.
- the steam chamber vessel 24 is filled with an appropriate amount of water and the cover 26 of the steam chamber is secured thereto as shown in Fig. 6.
- the cover 140 of the steam chamber is secured so that the steam exit port 146 is in communication with the steam inlet port 194 of the container 128.
- the container 14 and Hd 50 are then mounted to the base
- the container and lid are locked to the base by the complementary locking elements 82, 44 on the Hd and base, respectively.
- the steam exit port 36 is in fluid communication with the steam inlet passage 84. Electrical power is provided to the heater 22, causing the water in the vessel 24 to boil and steam to be generated in the steam chamber 16.
- the steam exits the steam chamber through the steam exit port 36 and enters the container 14 through the steam inlet passage 84 in the lid 50.
- the steam travels upwardly through the screen 86, thereby cooking the food. As the steam condenses, it returns to liquid form and drips through the screen 86 and onto the inner surface of the Hd 50.
- the apparatus may be provided with a timer (not shown) for setting the cooking time. It may also include a circuit (not shown) for terminating power to the heater 22 when the vessel no longer contains water or the water level is below a preset minimum.
- the container is removed from the base 12 and the condensate collector 90 is removed from the receptacle 40.
- the container 14 is placed on the base in the position shown in Fig. 5 such that its base portion 68 rests on the bottom tier 46 of the receptacle 40 and the projections 70 enter the bayonet-type slots of the first locking structure 42.
- the container is rotated to lock it in position on the base 12. Electrical power is supplied to the motor
- the blade assembly can be operated at a single speed or multiple speeds, as known in the blender art. Condensate from the collector 90 can be added to the container through the slotted opening 76 in the lid. Once the blending process is complete, the container assembly is removed from the base 12 and the contents removed for consumption or storage.
- the present invention permits the food to be chopped/pureed or blended and steamed without the food being touched by the user. It is also within the contemplation of the present invention that the container 14 with its food contents may be placed within the base to permit the food to be chopped and then placed in an inverted position in the base so that the food may be steam cooked. In order to operate the sterilizing unit, in the embodiment shown in Fig.
- the sterilizing unit 97 is mounted on base 12 such that the base receptacle 40 is disposed between the sterilization unit 97 and the steam chamber 16.
- the housing extension 100 is positioned adjacent the steam chamber such that the steam exit port 36 aligns with the steam inlet port 108.
- the sterilizing unit's cover 104 may be removed so that bottles may be placed within the sterilization chamber 98.
- the sterilization unit 198 is positioned on the base 122 adjacent to the steam chamber 124.
- the cover 140 may then be positioned and secured on the vessel 134 such that the steam exit port 146 is aligned with the steam inlet port 212.
- the heating element may then be energized to generate steam which flows into the sterilization chamber.
