Abstract

A method for operating a stand mixer includes receiving, at a controller of the stand mixer, a signal indicative of a parameter of food contents in the stand mixer, and receiving, at the controller of the stand mixer, a signal indicative of an operating parameter of a motor of the stand mixer while the motor operates to mix the food contents. Then, determining, at the controller of the stand mixer, that a mixing operation of the stand mixer is complete based at least in part of one of the signal indicative of the parameter of the food contents, the signal indicative of the operating parameter of the motor, and time. Then adjusting, with the controller of the stand mixer, operation of the motor when the mixing operation is complete.

First claim

What is claimed is:

1 . A stand mixer, comprising:
a housing that comprises a base, a column mounted to the base, and a head mounted to the column and extending outwardly above the base; a motor disposed within the housing; a drivetrain comprising a gearbox coupled to the motor and a mixer shaft coupled to the gearbox, the mixer shaft perpendicularly coupled to the gearbox with respect to the motor; an attachment coupled to the mixer shaft, the attachment configured to one of beat, whisk, or knead; a scale mounted to the housing; a controller disposed within the housing; a switch coupled to the controller, the switch configured to selectively activate the motor in response to user actuation of the switch; a relay coupled to the controller, the relay configured to selectively deactivate the motor; and a plurality of sensors in communication with the controller, wherein the controller is configured to receive a signal indicative of a parameter of food contents in the stand mixer from a first sensor of the plurality of sensors and a signal indicative of an operating parameter of the motor from a second sensor of the plurality of sensors when the motor operates to mix the food contents, the second sensor configured to measure torque of the drivetrain, and wherein the controller is configured to compute a stopping time based at least in part on the signals from the first and second sensors, the parameter of food contents and the operating parameter of the motor comprising two or more of weight, viscosity, time, temperature, altitude, speed, and electrical current.

2 . The stand mixer of claim 1 , wherein the switch is one of an electromagnetic switch and a servo switch.

3 . The stand mixer of claim 1 , wherein the controller is configured for communication with a remote device.

4 . The stand mixer of claim 2 , wherein the switch is configured such that the mixing operation is initiated via manual actuation of the switch.

5 . The stand mixer of claim 1 , wherein the parameter of food contents is one or more of weight, ingredient type and ingredient temperature.

6 . The stand mixer of claim 1 , wherein the operating parameter of the motor is one or more of torque, speed, time, and mixer temperature.

7 . The stand mixer of claim 1 , wherein the signal indicative of the parameter of food contents, received at the controller, is received from one or both of a user input and the first sensor.

8 . The stand mixer of claim 7 , wherein the scale is one of an integrated scale, a weight selection knob, side scale, and a drop scale.

9 . The stand mixer of claim 1 , wherein the signal indicative of the operating parameter, received at the controller, is received from one or both of a user input and the second sensor, the second sensor comprising one or more of a current sensor, a barometer, and a thermocouple.

10 . The stand mixer of claim 9 , wherein the current sensor is one of a Hall-effect current sensor and a current sensing resistor.

11 . A method for operating a stand mixer, the stand mixer comprising a drivetrain comprising a gearbox coupled to a motor and a mixer shaft coupled to the gearbox, the mixer shaft perpendicularly coupled to the gearbox with respect to the motor, and an attachment coupled to the mixer shaft, the attachment configured to one of beat, whisk, or knead, the method comprising:
receiving, at a controller of the stand mixer, a signal indicative of a parameter of food contents in the stand mixer; receiving, at the controller of the stand mixer, a signal indicative of an operating parameter of a motor of the stand mixer while the motor operates to mix the food contents, the signal indicative of a torque of the drivetrain; determining, at the controller of the stand mixer, that a mixing operation of the stand mixer is complete based at least in part of one or more of the signal indicative of the parameter of the food contents, the signal indicative of the operating parameter of the motor, and time; adjusting, with the controller of the stand mixer, operation of the motor when the mixing operation is complete.

12 . The method of claim 11 , wherein the controller is configured for communication with a relay and a switch.

13 . The method of claim 11 , further comprising communicating with the controller of the stand mixer from a remote user interface.

14 . The method of claim 11 , further comprising initiating the mixing operation via one of an electromagnetic switch and a servo switch.

15 . The method of claim 11 , wherein the parameter of food contents is one or more of weight, ingredient type, and ingredient temperature.

16 . The method of claim 11 , wherein the operating parameter is one or more of speed, time, and mixer temperature.

17 . The method of claim 11 , wherein the signal indicative of the parameter of food contents, received at the controller, is received from one or both of a user input and a sensor, the sensor comprising one or both of a thermocouple and a scale.

18 . The method of claim 17 , wherein the scale is one of an integrated scale, a weight selection knob, side scale, and a drop scale.

19 . The method of claim 11 , wherein the signal indicative of the operating parameter, received at the controller, is received from one or both of a manual input and a sensor, the sensor comprising one or more of a current sensor, a barometer, and a thermocouple.

20 . The method of claim 19 , wherein the current sensor is one of a Hall-effect current sensor and a current sensing resistor.
