A modular appliance apparatus is disclosed for use in the preparation of food products. The modular appliance apparatus may have a housing to contain internal components. The housing may contain a motor, a controller, and electronic circuitry. On a bottom portion of the housing, at least one base contact may be present. An attachment may secure to the bottom portion of the housing and contain at least one attachment contact. An electronic connection between the at least one base contact and at least one attachment contact may be interpreted by the controller to determine a speed of operation by the motor. Depending on the type of attachment secured to the housing, various different combinations of electronic connections may be made to operate the motor at different speeds to meet the requirements for food preparation by the specific attachment.

A vacuum blender according to the present invention comprises: a blender body including a container support case, an outer container seated in the container support case, a grinding blade, and a blade driving unit for rotating the grinding blade; an inner container unit including an inner container disposed in the outer container and in which the grinding blade is located, and an inner container driving unit for rotating the inner container; a vacuum unit installed in the container support case and configured to perform a blending operation on an object to be blended accommodated in the inner container in a vacuum state, wherein the outer container is opened and closed by means of an outer container cover, the inner container is opened and closed by means of an inner container cover, the inner container cover is assembled to rotate on the outer container cover.

A kitchen appliance has a control arrangement arranged to receive sound commands and to operate the appliance in response to the sound commands; a microphone arranged to receive sound comprising a sound command and to provide the sound to the control arrangement; and at least one acoustic filter configured to supress from the sound provided to the control arrangement background noise created by operation of the kitchen appliance.

Food processing apparatuses having a drive unit which has more than one mode of operation, works with more than one food processing container, and/or may be operated in more than orientation are disclosed. The drive unit may be operated in first and second modes of operation. In some embodiments, the drive unit may be actuated in a different manner in the second mode of operation as compared to the first mode of operation. In some embodiments, the orientation of the drive unit in the second mode of operation is vertically flipped upside-down as compared to the orientation of the drive unit in the first mode of operation.

A blender tool is disclosed for assisting in blending a substance within a blender. The blending tool comprises a primary body and a secondary body. A handle is coupled to the primary body. The primary body and the secondary body slidably engage for defining a telescoping engagement. The telescoping engagement provides a varying tool length. A slip nut engages the telescoping engagement for coupling the primary body to the secondary body and defining a fixed tool length. An appendage is coupled to the secondary body for increasing the contact surface area between the secondary body and the substance and improving the blending of the substance within the blender container. The varying tool length is configured for maintaining a separation between the secondary body and the mixing blade.

A food processing system includes a processing container having a motor-driven processing blade positioned at a bottom of the processing container, a lid receivable atop the processing container, and a motor-driven dasher assembly connected to the lid and being configured to scrape interior sidewalls of the processing container.

A blender includes a blender body including an external cylinder, a grinding blade, and a blade driving portion rotating the grinding blade; and an internal cylinder unit including an internal cylinder, disposed in the external cylinder, in which the grinding blade is disposed, and having an internal side surface, on which at least one projection is formed, and an internal cylinder driving portion rotating the internal cylinder, wherein the internal cylinder driving portion rotates the internal cylinder with an internal cylinder driving motor in a direction opposing a rotational direction of the grinding blade, and includes a blocking member preventing the internal cylinder from rotating in the same direction as the rotational direction of the grinding blade.

A blender having bi-directionally rotatable blades includes: a blade assembly including a main blade shaft that is provided to allow a first blade and a first main coupler to integrally rotate in a forward direction and a reverse-rotation blade shaft that is provided to allow a second blade and a first reverse-rotation coupler to integrally rotate in a reverse direction; and a gearbox assembly including a main gear shaft that is provided to allow a second main coupler and a main gear to rotate in the forward direction, at least one sub-gear that is engaged with the main gear and rotates in the reverse direction, a ring gear to which the sub-gear is internal and engaged, and a second reverse-rotation coupler that is configured to integrally rotate with the ring gear in the reverse direction and transmit the reverse rotation to the first reverse-rotation coupler.
