A blending device having an interlock system which may comprise a plurality of subassemblies. A thermal detector may be configured to be proximity with matter being blended for human consumption. Interlock system may further include a blade interlock contact and a compressive contact. The blender vessel may be configured to compress the compressive contact to a communicative configuration when connected with the blade assembly. Interlock system may utilize a blender base assembly that has base interlock contacts and a motor. The blade assembly may be configured to releaseably mount to the blender base assembly and may cause the base interlock contact and the blade interlock contact to come into electrical communication with each other. The interlock system may ultimately result in the motor being obstructed from operation unless certain conditions are met. The interlock system may further utilize one or more than one logic circuit element.

A blade hub assembly (10) for a kitchen device (120) having a receiving aperture (80) with a profile (90), the assembly (10) having a rotational axis (11) about which the assembly (10) is driven, the assembly (10) comprising: a hub body (20), the hub body (20) having: a first profile (30); and a second profile (40), the hub body (20) being insertable in the receiving aperture (80) in an insertion direction (50), and wherein the first and second profile (30, 40) are arranged such that, when the first profile (30) is aligned with the aperture profile (90), the second profile (40) interferes with the aperture profile (90).

A locking mechanism (104) for a kitchen device (101) having a vessel (105), the vessel (105) providing an interior space and having a rim (106) surrounding an opening (105a) of the space, and a lid (121) to engage the rim (106) to close the space, the locking mechanism (104) comprising: a retaining arm (107), the retaining arm (107) being attachable to the device (101) and movable between a free position, wherein the lid (121) is movable with respect to the vessel (105), and a retaining position, wherein the retaining arm (107) is engageable with the lid (121) to retain the lid (121) against the vessel (105) to at least partly close the opening (105a); a securing assembly (108), the securing assembly (108) being attachable to the device (101) to engage the retaining arm (107) and movable between a free position, wherein the retaining arm (107) may be moved between the free position and the retaining position, and a securing position, wherein the securing assembly (108) engages the retaining arm (107) to prevent movement of the retaining arm (107) from the retaining position; a processor; and an electric motor (157) operated by the processor to move the securing assembly (108) between the free position and the securing position.

A blender for processing comestible matter includes a base with a motor, a blade assembly, and a container. The blender further comprises a first safety mechanism and a second safety mechanism. The first safety mechanism functions to ensure that the container is securely attached to the blade assembly before the blade assembly can be mounted to the base. The second safety mechanism functions to ensure the motor in the base can only be powered on when the container and the blade assembly are securely mounted to the base. The blender is operable by affixing the container to the blade assembly, and then the assembly to the base, such that both safety mechanisms are released to permit the motor to be activated.

A blending system that includes a base that is selectively and operatively engaged with a container is shown and described herein. The base may include a near field communications chip that may communicate with a near field communications chip of a cutting disc. The cutting disc identifies a type of the cutting disc, a position of a chute of a lid or both.

A rechargeable blender with a locking mechanism is disclosed. Exemplary implementations may include a base assembly, a container assembly, a blending component, control circuitry, and/or other components. The blender includes a power interface configured to be manually engaged by the user, which facilitates transitions between a locked mode of operation and an unlocked mode of operation. Rotation of the blending component is selectively allowed or prevented based at least in part on the current mode of operation.

A food processing container includes a food processing chamber and a cover assembly with a latch mechanism operable between latched and unlatched positions. The latch mechanism includes a first magnetic member disposed therein. An interlock assembly is disposed outside of and adjacent to the food processing chamber and includes a sealed cavity with a plunger member moveable disposed within the sealed cavity. The plunger is operable between at-rest and actuated positions within the sealed cavity and includes upper and lower magnetic members disposed at opposite ends of the plunger member. The plunger member moves to the actuated position as the latch mechanism moves to the latched position due to a repulsion force between the first magnetic member and the upper magnetic member, and further wherein the lower magnetic member moves into the lower portion of the sealed cavity as the latch mechanism moves to the latched position.

A system for attaching a blender container to a blade assembly, which comprises a first mechanism to secure a blender container to a blade assembly. Some embodiments of the system include a second latch mechanism to lock the blender container to the blade assembly while the container and blade assembly are mounted to a base for operation of the blender.

A blender has a removable cap provided in a container lid. The blender includes: a container body configured to receive food; a blender body provided at a lower side of the container body and supporting the container body; and a container lid mounted removably to an upper surface of the container body and opening and closing the upper surface of the container body, where the container lid includes: a lid body having a lid hole vertically formed therethrough; the cap covering the lid hole; and a lock allowing the cap to be removably mounted to the lid body, the lock having a locking protrusion formed by protruding from the lid body to a side thereof, and a locking passage formed in the cap and receiving the locking protrusion.

A food processing container includes a food processing chamber and a cover assembly with a latch mechanism operable between latched and unlatched positions. The latch mechanism includes a first magnetic member disposed therein. An interlock assembly is disposed outside of and adjacent to the food processing chamber and includes a sealed cavity with a plunger member moveable disposed within the sealed cavity. The plunger is operable between at-rest and actuated positions within the sealed cavity and includes upper and lower magnetic members disposed at opposite ends of the plunger member. The plunger member moves to the actuated position as the latch mechanism moves to the latched position due to a repulsion force between the first magnetic member and the upper magnetic member, and further wherein the lower magnetic member moves into the lower portion of the sealed cavity as the latch mechanism moves to the latched position.
