Overheat prevention device for household bean milk and bean curd makers is disclosed. Such makers include a housing having a cavity to contain water therein, a main body, and a drive motor to rotate a cutting blade on an end of a drive shaft. A heater may be provided which generates heat when electricity is applied to the heater, thus heating an interior of the housing. Overheat prevention device includes a temperature sensing and fusing bar extending to a predetermined length to reach a position around the filter net and has a temperature sensor to detect an internal temperature of the housing, and a thermal fuse to cut off electricity supplied to the heater, when the interior of the housing overheats. Overheat prevention device allows the thermal fuse to accurately detect an internal temperature of the housing, therefore preventing the bean milk and bean curd maker from overheating.

What is claimed is: 1. 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. 2. A household bean milk and bean curd maker, the bean milk and bean curd maker, comprising: a) a housing having an upper portion, a lower portion, and defining a cavity to contain water therein; b) a main body provided at an upper portion of the housing configured for opening and closing the housing; c) a drive motor provided in the main body for generating rotary power when electricity is applied to the drive motor, in use; d) a drive shaft provided for transmitting the rotary power from the drive motor; e) a cutting blade provided at an end of the drive shaft; f) a heater extending downwardly away from the upper portion of main body toward the lower portion, and the heater being configured for generating heat when electricity is applied to the heater, in use, thus heating an interior of the cavity of the housing; g) a filter net detachably mounted to the main body, the filter net configured for containing beans therein, in use; and h) an overheat prevention device provided in the interior of the cavity, the overheat prevention device including a temperature and sensing and fusing bar extending sufficiently to reach a position around the filter net, and the temperature sensing and fusing bar being a one-piece element; i) the temperature sensing and fusing bar including: 1) a temperature sensor to detect an internal temperature of the housing; and 2) a thermal fuse to cut off electricity supplied to the heater, when the temperature sensor has detected that an internal temperature of the interior of the housing is overheated, in use; and j) the temperature sensing and fusing bar extending substantially the length of the filter net. 3. A household bean milk and bean curd maker as in claim 2, wherein: a) the heater extends substantially the length of the filter net. 4. A household bean milk and bean curd maker as in claim 2, wherein: a) the temperature sensing and fusing bar extends near to the heater.
