Patent ID: 7322281

Claim:
An overheat prevention device for household bean milk and bean curd makers, individually having a housing with a cavity to contain water therein, a main body provided on an upper portion of the housing to open and close the housing, a drive motor installed in a predetermined portion of the main body to generate rotating power when electricity is applied to the drive motor, a drive shaft to transmit the rotating power from the drive motor, a cutting blade provided at an end of the drive shaft, a heater extending downwardly from the main body to generate heat when electricity is applied to the heater, thus heating an interior of the housing, and a filter net detachably mounted to a predetermined portion of the main body to contain beans therein, the overheat prevention device, comprising: a) a temperature sensing and fusing bar, the temperature sensing and fusing bar being a one-piece element; b) the temperature sensing and fusing bar extending to a predetermined length to reach a position around the filter net; c) the temperature sensing and fusing bar extending substantially the length of the filter net; d) the temperature sensing and fusing bar including: i) a temperature sensor to detect an internal temperature of the housing; and ii) a thermal fuse to cut off electricity supplied to the heater, when the interior of the housing is overheated; e) the heater extending substantially the length of the filter net; and f) the temperature sensing and fusing bar extending near to the heater.
