Abstract: An appliance for preparing mayonnaise and similar sauces has a reservoir for oil or otherl iquid mounted above the mixing bowl. A mixing tool is rotatable within the bowl by way of a driven shaft which extends vertically and is also arranged to drive a dispensing device for controlling the flow of liquid from the reservoir to the bowl. The dispensing device includes a gear type proportioning pump having a toothed wheel which transports oil or other liquid from an intake orifice in the bottom of the reservoir to a delivery orifice communicating with the bowl.

Abstract: Apparatus for food preparation comprises a bowl, a rotatable tool within this bowl, and an arm which extends over the bowl and which contains a drive device for rotating the tool. The drive device includes a pinion to engage the drive shaft of the tool, and this pinion is fixed to, or preferably integral with, the drive shaft to define a drive assembly for the tool. This drive assembly is detachably mounted within a recess provided in the arm. An opening is formed in the arm through which the recess communicates with the exterior, and this opening is arranged to allow passage of said drive assembly therethrough.

Abstract: A blade set for an electrical knife comprises two parallel extending blades arranged adjacent with their inner faces facing and joined to one another. In use, for example, for slicing bread, the two blades are alternately reciprocated by the drive motor of the knife. Each blade has a series of indentations in its lower edge between which projecting teeth are defined. The tip of each tooth has a small concave notch, in the form of a circular arc, which extends between the edges of the tooth and which has a chamfer. The ends of this notch form two spaced points.

Abstract: An electric oven has a number of heating elements for heating the cooking chamber. A multi-position switch is arranged to couple power to all of the heating elements, such that the chamber can be used as an oven, or to only selected heating elements such that a grilling operation can be performed. However, when grilling it is best if the door of the cooking chamber is at least partially open so that air can circulate.The invention provides a mechanical linkage between the door and the switch such that if the switch is moved into its grill operating position, the door is automatically opened. In addition, if the door of the cooking chamber is closed, the switch is automatically moved into its oven operating position.

Abstract: A domestic electrical appliance for food preparation has a generally cylindrical bowl and a vertical shaft rotatably mounted in this bowl. A beating/emulsifying tool of the invention is arranged to be mounted on the shaft. The tool comprises a disc arranged to extend near the bottom of the bowl and to be rotated by the vertical shaft. A series of radially directed projections are formed on one or both of the faces of the disc which can be used alone in the appliance for the preparation of emulsions such as mayonnaise. A cage can additionally be mounted in the bowl to cooperate with the disc for the effective beating of foodstuffs such as egg whites and cream.

Abstract: A domestic coffee maker has a water reservoir and a water heater housed in the casing, and tubes for feeding water from the reservoir to the heater, and for feeding hot water to a discharge spout. The spout is arranged above a filter for holding ground coffee in a filter cone, and at the bottom of the filter there is an outflow aperture. A coffee jug is arranged to be supported on the casing to receive coffee flowing from the outflow aperture. A closure valve is provided for the outflow aperture and comprises a stopper carried on a pivotally mounted arm. The arm is displaceable by an opening lever mounted to be movable relative to the casing upon the removal from and positioning of the jug on the casing. When the jug is removed the opening lever displaces the arm such that the outflow aperture is closed by the jug.

Abstract: A domestic floor mop comprises an absorbent band mounted on a bracket carried at the end of a handle. A rotary torsion head is engaged with the band and is rotatably mounted in the bracket. A fastener is fixed to each end of the band, and the fasteners are monted on the bracket for movement between a washing position, in which said fasteners are spaced apart and said band is deployed in a plane, and a wringing position in which said fasteners are closer together such that said band is gathered towards said rotary head to permit twisting of the band upon rotation of said rotary head. The fasteners are each slidably mounted in a respective guide carried by said bracket and extending in a plane parallel to the deployment plane of said band.

Abstract: A mixer arranged for crushing food materials immersed in a liquid comprises a motor unit and a mixing foot. A shaft extends within the mixing foot and is coupled at one end to the motor unit. At its other end the shaft carries a mixing screw which is housed in a cover carried by said mixing foot. The mixing screw is movable between a safety position, in which it is located in the cover, and a mixing position, in which it projects outwardly of the cover. The mixing screw is moved into its mixing position against the action of elastic restoring means by a force resulting from the screwing effect in the liquid.

Abstract: A domestic electrical food processing appliance has a work bowl supported on a base and a detachable cover fixed on said bowl by a bayonet device. An electrical motor is mounted in the base and drives an output shaft which extends within the bowl and carries a cutting tool. The motor is actuated by depressing a push-button slidably mounted in a boss of the base. A safety bolt is pivotably mounted in the boss and urged into a locking position preventing depression of the push-button. The cover carries an arm which, when the cover is moved to its closed position, pivots the safety bolt out of its locking position to allow depression of the push-button. The engagement of the arm with the safety bolt also prevents removal of the cover from the bowl while the push-button is depressed.

Abstract: A water heater for a domestic coffee maker comprises a hot plate which is heated by an electrical resistance heater. A cavity is formed within the hot plate. The cavity extends substantially parallel to the top and bottom surfaces of the plate and has a closed end within the plate and an open end in the peripheral surface of the plate. The cavity is divided transversely by a partition which defines together with the internal walls of the cavity, a substantially U-shaped water circulation passage within the cavity. Water flowing through the U-shaped passage is thus heated by the heater.

Abstract: A domestic electrical appliance has a base supporting a work bowl. A removable cover for closing the bowl is fixed to the base by a rotary coupling. A motor unit is housed in the base and rotates a working tool positioned within the bowl. A push button is provided for controlling operation of the motor unit. Depression of the push button to actuate the motor unit also prevents removal of the cover from the bowl. A safety lock is provided which moves automatically to its locked position upon depression of the push button and in its locked position prevents the push button returning to its initial retracted position.

Abstract: In an electrically operable household appliance of the kind in which a detachable accessory, such as a vegetable cutter, is seated on the top of a base and includes a casing which contains working elements adapted to be coupled to the output shaft of an electric motor which is housed in the base and is controlled by a switch which is operable by a key situated in the top part of the base and is actuated by a push-button mounted on the accessory, the casing of the accessory is fixed to the base by at least one fastener comprising a hook which is articulated on the casing and has a hook portion arranged to come into engagement with the base, and the push-button is mounted on the hook.

Abstract: In an electrically operated household appliance, such as a foodstuff mincer or grinder, of the kind which comprises a casing the top of which supports a working bowl which is closed by a removable cover and in which rotate cutters driven by an electric motor which is disposed inside the casing and is controlled by at least one switch which has an operating key situated on the top part of the casing and is actuated by a skirt extending downwards from the cover. The cover comprises two parts connected telescopically, one part being constituted by the skirt and being displaceable relative to the other part which is a cap, between a lower position in which the skirt brings the operating key into the working position thereof, and an upper position in which the operating key is in its position of rest.
