Method of controlling motor of food mixer, base for food mixer

Abstract

A base for a food mixer includes a body in which a motor is mounted. The base further includes a control unit having a first touch control panel and a processor. The first touch control panel is mounted to a first side of the body. The first touch control panel includes a sliding section. A finger of a user is adapted to slide from an end towards the other end of the sliding section, producing a sliding signal indicative of a sliding distance and a sliding direction of the finger of the user. The processor is in direct or indirect electrical connection with the motor and the first touch control panel. The processor receives the sliding signal and includes a motor control program. The processor changes a speed of the motor according to the sliding signal due to sliding of the finger of the user alone the sliding section.

What is claimed is: 
     
         1 . A method of controlling a motor of a food mixer, the food mixer including a touch control panel, the method comprising:
 detecting a contact point with a touch sensitive section of the touch control panel, the contact point produces by a finger of a user;   contacting and sliding the contact point on the touch sensitive section of the touch control panel; and   changing a speed of the motor according to a sliding distance and a sliding direction on the touch sensitive section of the touch control panel.   
     
     
         2 . The method of  claim 1 , wherein the touch sensitive section having a first end and a second end, the gradually acceleration of the motor representative for the sliding from the first end of the touch sensitive section to the second of the touch sensitive section. 
     
     
         3 . The method of  claim 2 , wherein the gradually deceleration of the motor representative for the sliding from the second end of the touch sensitive section to the first of the touch sensitive section. 
     
     
         4 . The method of  claim 2 , wherein the lowest speed or the stop of the motor representative for the sliding at the first end. 
     
     
         5 . The method of  claim 2 , wherein the fastest speed of the motor representative for the sliding at the second end. 
     
     
         6 . A base for a food mixer, the base comprising:
 a body;   a motor mounted in the body;   a bulge extending a surface of the body; and   a control unit including a first touch control panel and a processor, the first touch control panel including a touch sensitive section, the first touch control panel connected to the bulge, the processor connected to the first touch control panel and the motor, the first touch control panel being responsive to a finger of a user sliding along the touch sensitive portion of the sliding section to produce a sliding signal indicative of a sliding distance and a sliding direction of the finger of the user, the processor controlling a speed of the motor according to the sliding signal.   
     
     
         7 . The base for a food mixer as claimed in  claim 6 , wherein the base includes a top side, the base further comprising a second touch control panel mounted on the top side of the base, the second touch control panel electrically connected to the control unit, the second touch control panel adapted to be touched by the finger of the user to control on/off of the control unit.
