ELECTRIC BLENDER

摘要

An electric blender (12) comprises a base unit (13) including an electric motor (14), a connecting line (18) for connecting the motor to a power supply, a separate glass container (15) incorporating rotatable blades (25) and engageable with the base unit so that the motor, when connected to the power supply will drive the blades, a lid (17) for closing the container but separable therefrom, an interlock switch (20) in said connecting line operable between closed and open conditions, the switch (20) being normally biased to its open condition and an enabling member (36A) integral with the lid and arranged to operate the switch (20) to the closed condition only when the container and its lid are correctly engaged with one another and the container is engaged with the base unit. The base unit (13) includes an upwardly extending stalk (31) in which the switch (20) is located and an actuator (34) movable vertically in the stalk (31) acting between the projection (36A) and the switch (20) and movable to 4mm beyond the position in which it first operates the switch to the motor enabled condition, so as to accommodate tolerance variations in the container height. The projection (36A) and actuator (34) also interengage in such a manner as to accommodate lack of concentricity of the glass container (15).
