This programmer comprises programme-cams corresponding to a plurality of programmes having clearly separate starting points disposed at angular intervals from one another. It further comprises a control element adapted to be rotated manually for selecting the initial position of one of the programmes. This element comprises lateral pins adapted to engage corresponding orifices formed in a coaxial registering control cam. On the opposite side of this cam a disc rigid with the programme-cams is provided; this disc is rigid with the programme-cams but spaced therefrom. The disc comprises ramp means cooperating with bearing faces formed in the control cam. Spring means interconnect the disc and the control cam in diagonal directions. The ramp means and their bearing faces are so oriented that when the control element is driven manually in the forward direction the control cam rotatably driven by the pins is shifted axially away from the manual control element by the ramp means with the assistance of spring means until the beak of an arm is actuated for controlling a switch adapted to control the fast rotation of the disc. When the disc is thus driven automatically for step by step rotation at a fast rate its ramp means cause the control cam to be shifted towards the control element, the pins engaging again the corresponding orifices until the beak is actuated again, the switch being thus actuated for stopping the fast rotation of the disc and programme-cams for ending the programme selection.

Programmer

The present invention relates to a programmer control device comprising a rotary cam block capable of being driven in rotation step by step by an advancing cam actuating an oscillating pawl carrier. The control device possesses means of blocking and releasing the action of the pawl, comprising a blocking lever 50' interacting with means capable of rocking the said blocking lever between two angular positions during each to-and-fro movement of the advancing pawl. In the first position, a part 51' of the blocking lever is located in the path of a slope 55 of the pawl 21, so as to prevent the action of the latter. In the second position, the part 51' is not located in the path of the pawl 21, so as to permit the action of the latter. Retention means, such as the nose 79a of a release lever 69a, which can be actuated, for example, in a delayed manner, are capable of retaining the blocking lever 50' in its second angular position counter to the action of the spring 49, to release the action of the pawl 21 at the end of a certain delay period. The invention can be used to control, in particular, a clothes washing machine or a dish washing machine.

Programmer control device

A programmer comprising a cam unit which can be rotated manually in a first direction by a control shaft 23 able to occupy, under the action of a pawl device comprising a spring, any one of several equidistant stable angular stop positions spaced apart by the angular value of one step, before passing on each occasion through a limiting unstable intermediate angular position, after which this shaft is brought in a resilient manner by the pawl device towards the following stable angular stop position. A motor and drive transmission system are able, when controlled, to rotate the cam unit step by step in said first direction. The cam unit is connected to rotate with the control shaft, with an angular clearance less than the angle through which the shaft travels, between any one of its stable angular stop positions and the limiting unstable intermediate angular position which follows.
