Abstract

A stand mixer 10 comprises a head unit 50 having a lower surface presenting, in operation, a downwardly-facing drive outlet for driving in rotation at least one tool suspended therefrom. The head unit is supported with the downwardly-facing drive outlet above a receiving location 30 for a mixing bowl 40. Driving means, including an electric motor 70 and associated transmission means for conveying rotary drive to the drive outlet, are provided. The mixer further comprises first 80 and second 90 coaxial driving outlets presented on an upper surface 52 of the head unit 50; the coaxial outlets 80, 90 run at different speeds and are driven from the motor 70 by means of an epicyclic gearbox 100. The motor 70 is housed in the support means 60 with its drive shaft 72 in substantial alignment with the coaxial drive outlets 80, 90.
