Hand-held immersion blender
A hand-held appliance having a housing with a top portion and a bottom portion that houses a motor and a temperature sensor configured to monitor the motor temperature and, if the temperature reaches a predetermined threshold, trigger removal of power until the temperature is below the threshold. The motor is controlled via a power button located on an external face of the housing. The housing includes a speed-set-button located on an external face of the housing controlling the speed of the motor and a plurality of lights corresponding to the respective speed thereof. The bottom of the housing includes a coupling portion configured to receive an attachment such as a blending assembly, whisk, frothing assembly, or other attachment. The housing further includes a sensor configured to monitor motor performance and applied load and, if the load exceeds a predetermined threshold, trigger removal of power from the motor.
1. A hand-held blending system, comprising:
a handle-shaped elongate housing that houses a motor and at least a portion of a first drive shaft having a proximal end and a distal end, the proximal end of the first drive shaft drivingly engaged with the motor;
a control panel comprising at least two user interface devices;
a display located on the housing;
a second drive shaft configured to selectively couple the first drive shaft to drivingly engage with the motor;
a cup portion positioned at the distal end of the second drive shaft;
a blade assembly operatively coupled with the second drive shaft; and
a magnet positioned at the distal end of the second drive shaft;
wherein the magnet and the blade assembly are disposed within the cup portion to produce a magnetic field to heat the blade assembly.
2. The hand-held blending system of claim 1 , further comprising at least one sensor that transmits monitoring signals corresponding to one or more characteristics of the motor.
3. The hand-held blending system of claim 2 , wherein the at least one sensor comprises a temperature sensor that transmits signals corresponding to a temperature of the motor.
4. The hand-held blending system of claim 2 , wherein the at least one sensor comprises a stall sensor that transmits signals indicating a stall condition of the motor.
5. The hand-held blending system of claim 1 , wherein the at least two user interface devices include a power button and a speed button.
6. The hand-held blending system of claim 1 , further comprising at least one wireless communication device, selected from a near-field communication device (NFC) device, a Bluetooth device, and a Wi-Fi device.
7. The handheld blending system of claim 1 , wherein the magnet is an electromagnet that is actuable via one of the at least two user interface devices.
8. The handheld blending system of claim 1 , wherein the blade assembly and the magnet are disposed within the cup portion such that the magnet is positioned between a wall of the cup portion and the blade assembly.
9. The handheld blending system of claim 1 , wherein the magnet is incorporated into or integrated with the blades.
10. A hand-held kitchen appliance, comprising:
a handle-shaped elongate housing having a top and bottom;
a motor disposed within the housing;
at least one sensor disposed within the housing; and
a blending attachment removably coupled to the housing, the blending attachment further comprising:
a first drive shaft having a distal end extending from the bottom of the housing and a proximal end drivingly engaged with the motor;
a second drive shaft configured to selectively couple the first drive shaft to drivingly engage with the motor;
a cup portion positioned at the distal end of the second drive shaft;
a blade assembly disposed within the cup portion and operatively coupled with the second drive shaft;
a magnet disposed within the cup portion; and
an exciter disposed within the cup portion and positioned proximate to the magnet to produce a magnetic field to heat the blade assembly.
11. The hand-held kitchen appliance of claim 10 , wherein the motor has a predetermined maximum operating load.
12. The hand-held kitchen appliance of claim 10 , wherein the motor has a predetermined maximum operating temperature.
13. The hand-held kitchen appliance of claim 12 , wherein the at least one sensor comprises a temperature sensor.
14. The hand-held kitchen appliance of claim 13 , wherein the temperature sensor is coupled with a power source and removes the power source when the motor is operating at or near the predetermined maximum operating temperature.
15. The hand-held kitchen appliance of claim 10 , further comprising at least one wireless communication device, selected from a near-field communication device (NFC) device, a Bluetooth device, and a Wi-Fi device.
16. The hand-held kitchen appliance of claim 15 , wherein the at least one wireless communication device communicates information about the blade assembly, wherein the information includes operation, functionality, or proper attachment.
17. The hand-held kitchen appliance of claim 10 , wherein the magnet is an electromagnet that is actuable via a user interface device.
18. The hand-held kitchen appliance of claim 10 , wherein the magnet may be operatively coupled to the second drive shaft such that the magnet rotates with the second drive shaft.
19. The hand-held kitchen appliance of claim 10 , wherein the exciter comprises a barrier that extends radially from the second drive shaft and encloses the magnet within a sealed chamber that is separate from the blade assembly.
