Definitions

  • the present teachings relate to a blending system, and more particularly, to a high performance, small format blending system.
  • Blending systems are often used to blend and process foodstuffs.
  • personal blending systems have been developed with blending containers that are designed to serve a dual purpose and function as both a blending container and a drinking vessel.
  • the container may include the foods for blending and then will connect at its top with a blade assembly.
  • the user may invert the container/blade assembly so that the container/blade assembly engages with the personal blending system base.

  • the reed switch When the magnets 196 and 208 within the tabs 192, 204, respectively, are moved in operative proximity to the reed switch, the reed switch will close, i.e., the reed switch will close when a magnetic field is present. Once the magnets 196 and 208 are moved away from the switch, the reed switch will go back to its original open position.
  • the motor When the reed switch is in the open position, the motor is configured to be disabled, i.e., not operate. When the motor is disabled, the blade base 28 and more particularly, the blade 124 is not capable of operation. Therefore, in order to operate the blending system 20, the blending container 32 and blade base 28 must be operatively coupled with the blender base 24. Specifically, the tabs 192 and 204 must be operatively positioned within the first and second recessed portions 220, 224, respectively in order for the blending system 20 to operate. This generally prevents the user from being able to access or otherwise contact the blade 124.
  • the aforementioned interlock feature 34 is further configured to generally prevent circumvention by a user.
  • the reed switch may be calibrated to disengage or disable the motor anytime the magnet 196 or second magnet 208 or both are a predetermined distance away from the reed switch.
  • the predetermined distance may be calibrated so that the user may not create enough space between the blending container 32, blade base 28, or blender base 24 to access the blade 124.
  • the blending system 20 While the blending system 20 is operating, i.e., the motor is operating, the blending system 20 tends to attempt to rotate the blending container 32 relative to the blender base 24.
  • the tabs 192 and 204 being engaged with the first and second recessed portions 220, 224, respectively may prevent the blending container 32 from rotating - it may maintain the blending container 32 in its operative position with respect to the blender base 24.
  • the tabs 192 and 204 may be generally rectangular in shape. Further, the corresponding first and second recessed portions 220, 224 may be of a corresponding rectangular shape. The rectangular shape may provide the anti-rotation feature generally keeping the interlock feature 34 operatively aligned.
  • the blender base 24 may include a visual indicator, such as an LED or the like, to provide feedback to a user on the status of the interlock feature 34.
  • the visual indicator may provide a slow flash if the machine is plugged in but the container is not properly in place on the blender base 24.
  • the visual indicator may provide a solid (no flash) light if the machine is plugged in, the container is in place, and the machine is ready to blend.
  • a fast flash may be provided by the visual indicator if an error occurred, such as: the blender base 24 is plugged in while a variable speed control is not in the stop position; a container was placed on the machine while the variable speed control is not in the stop position; and/or a container was removed from the machine while operating.
  • the blade base 28 may further include a gasket 232 configured to provide a seal between the blade base 28 and blending container 32 when coupled together.
  • the gasket 232 may have a generally X-shaped cross section, such as shown in Figure 11.
  • the gasket 232 may generally span the periphery of the blade base 28 such that when the blade base 28 and blending container 32 are coupled - such as being threaded together - the gasket 232 is positioned along the entirety of a location of engagement between the blade base 28 and blending container. While the gasket 232 is shown as having a generally X-shaped cross-section, it will be appreciated that the gasket 232 may have any appropriate cross-sectional shape that performs the same function described below.
  • the gasket 232 may have a diameter of a narrow portion d that is shorter than a diameter of a distended portion do, such as shown in Figure 12.
  • the gasket 232 may be formed of any appropriate material, including, but not limited to, polymeric materials such as elastomers or rubbers including thermoplastic or thermoset elastomers, rubber-based materials, and other polymers and co-polymers having properties consistent with the features described above.
  • the gasket 232 may be configured to seal at low pressures and allow gas to exit at pressures that exceed a predetermined pressure within the blending container 32 during operation of the blending system 20.
  • the gasket 232 may function as a seal when the internal pressure zone within the blending container 32 exists from zero pressure to the predetermined level of pressure. After the internal pressure zone within the blending container 32 exceeds the predetermined level pressure - this may be considered a high pressure condition— the configuration of the gasket 232 may displace the gas within the blending container 32 to safely relieve pressure from the internal pressure zone, as shown in Figure 12.
  • the gasket 232 also maintains its operative position between the blending container 32 and the blade base 28 so that material within the blending container 32 does not leak as shown in Figure 19.
  • the friction of the spinning blade 124 may generate heat within the blending container 32.
  • the pressure may continue to build up to a predetermined level. If the force of the internal pressure zone increases above that predetermined level, the gasket 232 is configured to displace that internal pressure to allow interior pressure to escape into the atmosphere. The shape of the gasket 232 allows the internal gas of the blending container 32 to escape while the solids and liquids remain within the blending container 32. Thus, the pressure within the blending container 32 is generally prevented from exceeding a predetermined level.
  • the blending system 20 may, however, include a spill moat 236 if any liquid escapes from the blending container 32 either during operation, during insertion of the material to be blending or while expelling the material from the blending container 32.
  • the spill moat 236 may be of any appropriate configuration and may be positioned in the pedestal 76. By way of a non-limiting example, the spill moat 236 may be positioned on the periphery of the pedestal 76.
  • the spill moat 236 may be configured to capture any escaping liquid and allow it to flow along a predetermined path.
  • the blender base 24 may include at least one aperture 238.
  • the aperture 238 may be configured to allow the liquid to exit from the blending system 20.
  • the combination of the spill moat 236 and aperture 238 may generally prevent liquid from inadvertently entering the blender base 24 and more specifically from entering the working components of the blending system 20, such as the motor.
