Publication number: 20170071413Abstract: The present invention relates to a blender heatable by the high frequency induction heating of a new structure which enables food ingredients in a container to be easily cooked by heating. According to the blender, when a user drives the power supply unit 14 by manipulating the input means 31, the heating plate 24 is heated at a high temperature, and the food ingredients 1 inserted in the container 20 is heated. In addition, there is an advantage that the use of the blender is very convenient since the food ingredients 1 may be cooked by heating the food ingredients 1 in the state of being in the container 20 after grinding the food ingredients 1 using the blender. In addition, since the heating plate 24 is heated by the magnetic force generated in the induction coil 13 provided in the main body 10, the heating plate 24 may be heated at a high temperature in short time, and also the temperature of the heating plate 24 may be finely controlled.Type: ApplicationFiled: September 9, 2016Publication date: March 16, 2017Inventor: Chan Hong PARK
