A multi-purpose handheld kitchen appliance includes a controller configured to customize various aspects of the appliance based upon a type of attachment coupled to the appliance, e.g., to controllably vary a motor speed, to selectively disable an activation control, and/or to rotate a display based on a type of attachment and/or a gyroscope input.

The present invention relates to a hand mixer having a heat activation function. The heat activation function preferably allows a user to heat ingredients that are to be mixed by a hand mixer. The hand mixer may include a cavity that has each of a fan, a motor to drive the fan, heated coils, and an output area or mouth. When a user wishes to activate the heating function to soften ingredients in a bowl or other vessel to be mixed, he or she may use a controller to activate the fan and blow air through the heated coils and out from the output area toward the ingredients to be mixed and/or mixing devices used to mix the ingredients, so that the ingredients may be softened.

A mixer includes: a housing containing a motor and first and second beater mounting locations; and first and second beaters. Each of the first and second beaters comprises: an elongate shaft that defines a longitudinal axis between first and second ends; and a blade complex including a central body and at least three blades, the central body attached to the first end of the shaft, the blades attached to and extending radially outwardly from the shaft, each of the blades including a partially helical radially-outward edge, each blade including a continuous surface devoid of openings between the body and the radially-outward edge.

A multifunctional food processor includes: a container, in which a chamber is formed; and a power device, including a shell, where a sliding component mounting cavity is formed in the shell, a sliding component is mounted in the sliding component mounting cavity in a sliding manner, an elastic device is arranged between the sliding component and the shell, a pressing structure and the sliding component are connected to drive the sliding component to slide up and down, a spiral rod mounting cavity is formed in the sliding component, a mounting hole is formed in one end of the sliding component and is interconnected with the spiral rod mounting cavity, the mounting hole and a spiral rod are mated, and any of a dewatering device, a cutting device and a stirring device can be in transmission connection with the spiral rod.

A hand-held housing for a multi-purpose food preparation appliance, has at least one first drive output configured to drive a removable rotary work tool, an opening configured for mounting a removable work accessory, retaining members configured to engage with a connecting element of the work accessory mounted in the opening, and a second drive output configured to drive a rotary drive unit of the work accessory mounted in the opening.

The retaining members are arranged on an outer part of a protrusion arranged inside the housing around the second drive output, the retaining members being configured to engage with an inner part of the connecting element.

An electric hand mixer comprises a housing having at least a bottom surface and a rear heel surface, a motor within the housing, one or more holes defined in the bottom surface for receiving a respective rotatable beater, and a power cord extending outward from the housing. A recess is defined in the housing. A first opening to the recess is defined in the bottom surface. A second opening to the recess is defined in the rear heel surface. The first and second openings are continuous with each other. The power cord extends outward from within the recess.

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 hand mixer has a detection mechanism for discriminating between beaters and other rotating accessories. The operation of the mixer may be altered depending on the type of accessory that is detected.

An implement attachment holder for a hand mixer includes a body defining opposed first and second surfaces and first and second mounting projections coupled with the body and extending away from the first surface of the body at respective first and second locations spaced apart at a first distance along a first direction. The attachment holder further includes a device retention projection extending away from the second surface of the body and partially along the first surface to at least partially overlie the first and second locations from which the first and second mounting projections extend. The device retention projection further defines at least three attachment channels extending in a second direction normal to the first direction at spaced-apart locations along the device retention projection.

A multi-purpose handheld kitchen appliance includes a controller configured to customize various aspects of the appliance based upon a type of attachment coupled to the appliance, e.g., to controllably vary a motor speed, to selectively disable an activation control, and/or to rotate a display based on a type of attachment and/or a gyroscope input.
