Kitchen appliance, food processor and safety interlock arrangement

A food processor for a kitchen appliance, comprising:

• a compartment for processing food ingredients, the compartment having an outlet for outputting processed foods;
• a lid for closing the compartment;
• and
• a drive shaft extending through the compartment for driving a tool, the drive shaft rotatably bearing on the lid, wherein the drive shaft comprises one or more engagement elements arranged to be engaged so as to transmit drive to the drive shaft, wherein the engagement elements are provided at an end of the drive shaft remote from the lid;
• wherein the lid is removable from the compartment for allowing inspection, maintenance and cleaning of the compartment, and
• wherein the drive shaft is engaged by a coupling provided in a transmission assembly when the compartment is sealed by the lid when the compartment is mounted to a housing containing the transmission assembly, wherein removal of the lid from the compartment while it is mounted to the transmission assembly causes the drive shaft to disengage from the coupling, and causes the shaft to move from a first position wherein it is engaged by the coupling to a second position in which the transmission assembly is arranged to inhibit rotation of the drive shaft, and wherein one or more interference elements are arranged to interfere with rotation of the drive shaft when the lid and the housing are uncoupled.

A kitchen appliance, comprising:

• a base unit;
• a bowl arranged to be mounted to the base unit;
• a rotatable bowl tool mount provided within the bowl for a food processing tool, the bowl tool mount arranged to be driven by the base unit;
• a food processor having an outlet for outputting processed foods, the food processor being arranged to be mounted to the base unit;
• wherein the food processor is arranged to process food ingredients in a processing compartment and to output the processed food ingredients from the outlet into the bowl during operation of the kitchen appliance without interruption of drive to the bowl tool mount;
• and
• wherein the food processor is arranged to be driven independently of the bowl tool mount provided within the bowl, and
• wherein the food processor is mounted to the base unit via a housing containing a transmission assembly arranged to transmit drive from the base unit to the food processor, wherein the processing compartment is detachably mountable to the housing, a further comprising a lid arranged to seal with a rim of the bowl, the lid having an aperture aligned to receive processed food ingredients output directly from the food processor from a position spaced above the bowl.
