１項又は第３項に記載の装置。[Claims for Utility Model Registration] 1. In a mixer or juicer mixer, a current that has a bimetallic function near a heat-generating member whose temperature rises during operation of the motor, and which opens a contact when an excessive current is applied due to the heat-generating effect in the conductive part of the current. The present invention is characterized in that the protector is attached, thereby increasing the ambient temperature of the current protector and hastening the operation of the current protector, thereby making it possible to promptly cut off the circuit and stop the motor operation when the motor is overloaded. overload protection device for mixers and juicer mixers. 2. The device according to claim 1, wherein the heat generating member is a motor frame, and the current protector is attached to the motor frame via a mounting plate. 3. The device according to claim 1, wherein the heat generating member is a resistor connected in series with the motor, and a current protector is attached to a mounting plate that conducts heat generated by the resistor. 4. The heat generating member is a resistor connected in series with the motor, a temperature switch element such as a thermostat having normally open contacts is connected to both ends of the resistor, and the temperature switch element is activated when the ambient temperature is high, 4. The device according to claim 1, wherein both ends of the resistor are short-circuited to eliminate heat generation in the resistor and to prevent the ambient temperature of the current protector from becoming abnormally high.
