Kitchen appliance with detachable pull string drive for rotation
A recently filed patent (Publication Number: US20230313783A1) describes a new kitchen appliance that features a self-contained pull string drive device and a work unit. The device is designed to manually rotate the work unit around a rotation axis by pulling a string transversely to the rotation axis. The pull string drive device includes a drive wheel, a return spring, and a string, with one end of the string wound around the drive wheel and the other end connected to a handle. The work unit consists of a lid that closes a bowl.
One notable aspect of this kitchen appliance is that the pull string drive device can be detached from the lid of the bowl. The lid itself has a male or female part that is joined to a drive interface, allowing for mechanical coupling with the drive wheel. This mechanical coupling enables the transmission of rotational movement from the device to the work unit. Additionally, the pull string drive device can be easily released, attached, or detached from the lid of the bowl.
The appliance also includes a fastening system that allows the device to be temporarily and reversibly fastened to the lid of the work unit's bowl. In one embodiment, this fastening system is a bayonet fastening system. The mechanical coupling between the drive wheel and the lid is of the male/female type, with the drive wheel comprising a female part that cooperates with the male part of the lid. The female part of the drive wheel has a space on the lower side for the mechanically coupled accommodation of the work unit, facilitating the transmission of rotational movement.
The drive interface and the male or female part of the lid can be immobilized relative to each other, and they can be connected by locking means such as screws, keys, or pins. The drive interface also includes a housing for receiving the drive shaft positioned in the work unit. Furthermore, the appliance features a translational locking system that immobilizes the pull string drive device relative to the lid. This translational locking system includes a stop pin positioned on the lower side of the device, which cooperates with a housing for the lid to align the drive wheel and the work unit.
Overall, this patent describes a kitchen appliance with a unique pull string drive device that allows for manual rotation of the work unit. The detachable nature of the device and the various locking and fastening systems provide convenience and versatility in its use.
