摘要:
An appliance controller includes a plurality of auxiliary inputs for adjusting parameters of appliance operation such as washing machine operation (e.g. water temperature, rinse options, water level, speeds and/or the like). Each auxiliary input unit acts as a low power potentiometer. The various auxiliary units are connected in series. Each auxiliary unit produces a variable resistance based on position of a control knob of the auxiliary unit. The auxiliary inputs cooperate with each other to produce a unique aggregate resistance signal for the particular arrangement of users knobs of the various auxiliary input units. This unique resistance signal is sent to the processor thereby providing user selection information relating to the various auxiliary input units to the processor. In one form, each auxiliary input unit requires only two wires thereby eliminating a substantial amount of wiring. In one form, a detent plate and associated grooves is provided to simulate tactile feedback experienced when a traditional appliance input knob is rotated.

The invention relates to a rotary switch as operating device for contactless switching on and off and for automatic control of a number of programme sequences in electrically-operated units, such as washing machines, washing dryers, dishwashers or similar units. In order to simplify the assembly and maintenance thereof said rotary switch (1) comprises mutually communicating ratchet devices and a plate arranged at a separation therefrom with a Hall-effect rotating field sensor. Spring-loaded ball ratchets permit a distinct switching rotation of an operating piece (2) with magnetic devices in ranges up to 360° and angle-dependent parameter values are generated in a conventional manner in the rotational field sensor for the control of various programme sequences.

A programmer/timer for an appliance of the type having a rotatable program cam drum (45) advanced by an oscillating paw (76) engaging a ratchet wheel (48) for actuating at least one appliance function switch. A shaft (16) is provided for enabling user positioning of the cam after limited rotational lost-motion for selecting the program interval. An annular member (34) having a conical cam (40) surface is received over the shaft and is helically cammed to the shaft. During the limited lost-motion rotation of thE shaft, the collar moves axially and the conical cam surface lifts the paw from the ratchet thereafter enabling user rotation of the program cam for positioning same for program interval selection.

A programmer for an appliance having a single timing motor drive (148) for a rotating cam drum (112) which actuates plural appliance program function switches (120). A first advance means (125,126) drives the cam drum in one direction when selectively engaged with a toothed wheel (125) on the drum and drives through a first rotary frictional coupling (137). A second advance means (146,140) drives continuously through a second rotary frictional coupling (151) and drives the cam drum in a reverse direction when the first advance means is disengaged. When the first advance means is engaged, the second rotary frictional coupling slips and is overdriven in a direction opposite its driving direction by said first frictional coupling.

A bi-directional advance gear (10) having a torque limiting radial friction clutch is disclosed. The friction clutch comprises an annualr member (26) having an inner and outer periphery and having gear teeth (24) defined by its outer periphery and radially inwardly projecting teeth (56) on its inner periphery. A flat web (32) substantially closes one face of the annular member to provide a shallow recess (34) bounded by the projecting teeth and defines an opening (36) concentric to the annular member. An inner member having a hub portion (4) is rotatably mounted in the opening and has a pinion gear (28) at one end. The other end of the hub has a plurality of radially extending rosette-shaped springs (58) contained in the recess. Each spring has a pair of radially extending leg portions joined by an arcuate portions (66) Each arcuate portion has a lobe (68) biased into engagement with the inwardly projecting teeth.

A programmer/timer for an appliance of the type having a rotatable cam drum (12) advanced for sequential actuation and deactuation of a plurality of electrical switches (20). The drum is advanced or indexed intermittently by an oscillating advance pawl (26) engaging a ratchet wheel (25) and also continuously by a gear (44) driven by a common motor for oscillating the advance pawl. The ratchet wheel (25) has a hub (38) which is frictionally engaged (37) to drive the cam drum. The driven gear in turn is frictionally engaged (51) with the hub to also drive the ratchet wheel. When the advance pawl engages the ratchet wheel for intermittent drive, the driven gear slips on the ratchet hub. Upon user selection, a separate cam track (52) lifts the advance pawl to permit the driven gear to continuously drive the ratchet wheel.
