  • Patent number: 5979806
    Abstract: A food processor is known which comprises a base unit (1, 6) having at least two separate mounts (2, 3) for one processing container (4, 5) each. A respective rotary drive shaft is disposed in the area of each mount (2, 3), which drive shaft is adapted to drive a processing tool (9) insertable into the processing container (4, 5) for the processing of food materials. The drive shafts are connected to an electric motor (29) by a transmission mechanism. A switch device (S1) is provided downstream from and in series with a manually actuatable main switch (8; S3) to enable electric current to be released to the motor (29), said switch device being adapted to be turned on or off by movement of a lid (10, 11) which closes or opens the respective processing container (2, 3), such that an actuating element (13, 14) formed on the lid (10, 11) displaces a lever arrangement (15) connected with the switch device (S1) in such fashion as to cause actuation of a switching contact (23).

  • Patent number: 5875706
    Abstract: A food processing apparatus with a base unit (1) which has at least two separate mounts (2, 3), each for one processing bowl (4, 6), with one drive member (7, 8) positioned in the area of each of the mounts (2, 3) and being in driving connection with an electric motor, is equipped with a safety device. This safety device serves the purpose of ensuring that only one processing bowl (4) at a time can be mounted on the appliance in an operating position, while the safety device inhibits a second processing bowl (6) from being accommodated in the other mount (3). To accomplish this, a safety element (11) is provided which is adjustable between two blocking positions. When the safety element (11) is in the one position, the first mount (2) is rendered unable to accommodate a processing bowl while the second mount (3) is enabled to accommodate a processing bowl.

  • Patent number: 5550343
    Abstract: The invention is directed to a switch (2) for electrically powered apparatus, in particular for domestic appliances, with a rotary actuating shaft (4) transmitting the switching operation from a rotary handle (5) to a switch contact (15, 16), the actuating shaft (4) including a longitudinal bore (24) in which an actuating rod (5) is axially movably disposed, an end of said rod being adapted to be urged into the actuating shaft (4) for a depth of some length in opposition to a restoring force and converting an axial motion into a radial switching operation of control cams (23) acting on the switch contacts (15, 16). This provides a convenient short-time operation in a simple manner.

  • Patent number: 5297475
    Abstract: The invention is directed to a multi-purpose kitchen apparatus for processing foods, with a container (1) having arranged in a bore (20) in a container bottom (2) a bearing sleeve (4) in which a tool shaft (5) extending through the container bottom (2, 3) is journalled for rotary movement therein. The one end (35) of the tool shaft (5) is adapted to be connected with a drive motor through a coupling means (7), while the other (23) end is adapted be connected through a coupling member (8) with a processing tool for processing the foodstuffs. The bearing sleeve (4) is secured within the bore (20) of the container bottom (2, 3) by means of at least one resilient intermediate ring (9, 10) radially surrounding the bearing sleeve (4). This results in a bearing arrangement which affords particular ease of manufacture, is stable and has a low noise level.

  • Patent number: 5244275
    Abstract: The invention is directed to an electrically powered food processing apparatus for processing and preparing any type of food, receiving in a housing (1) an electric motor (8) rotating a processing tool located in a working vessel for processing the food material. The electric motor (8) is supplied with cooling air by means of a motor-driven impeller (38) rotatably arranged in the housing (1), and the electric motor (8) and the impeller (38) are disposed in an air duct (4) providing at its one end an air inlet (45) and at its other end an air outlet (46). To obtain a food processor of a construction as compact as possible, yet with a high motor output rating, while at the same time motor noise is reduced, the impeller (38) is driven by an additional electrically powered impeller motor (30) arranged in the housing (1) separate from the electric motor (8), and the impeller motor (30) is not connected to the supply until a predeterminable power input of the electric motor (8) is exceeded.

  • Patent number: 4995164
    Abstract: The invention is directed to a can opener (1) having in its casing (2) a drive unit which is comprised of an electric motor (32) secured to a mounting plate (41), a gear train (33) and an output shaft (42) driving the drive wheel (17). The longitudinal axis (8) of the casing (2) along which the electric motor (32), the gear train (33) and the output shaft (42) are arranged forms with the direction determined by the input shaft (70) of the electric motor (32), the shafts (61, 62, 63) of the gear train (33) and the output shaft (42) of the drive wheel (17) an angle (a) which is smaller than 90.degree..
