Definitions

  • the subject of the present invention is a programmer for an apparatus, or system, provided with a plurality of electrical members to be fed selectively and sequentially, a programmer comprising a plurality of cams cooperating with a plurality of contacts for supplying said members, and means for driving said cams in movement.
  • Such a programmer is used in particular in the household appliance field, for devices such as washing machines for washing clothes or dishes, for example.
  • Programmers of the type defined above are also known, for which the members to be supplied are divided into two groups.
  • the first group is supplied via relay switches controlled by an electronic circuit.
  • the second group is supplied via contacts actuated by a block of cams, in a similar manner to what has just been described.
  • Such a programmer is therefore partially adaptable, insofar as it makes it possible to electronically choose and vary the duration of drive of the drum in one direction, then in the other, for example. In addition, this choice has no influence on the control of the solenoid valve, the pump, and the resistance.
  • Such a programmer is often called a hybrid programmer because it combines mechanically controlled contacts and electronically controlled relays. It partially solves the problems linked to the lack of adaptability of the programmer already described, which includes a single block of cams to control all of the members. However, the need to use relays increases the cost price of the programmer and reduces its reliability.
  • the present invention aims to overcome the above drawbacks by providing an at least partially adaptable programmer, with a moderate cost price, and reliable.
  • said cams are distributed in first and second blocks, - said drive means are arranged to drive said first block in both directions, and, - Means are provided for mechanical coupling between said first and said second blocks, active in one direction.
  • the drive means drive the first block in the direction where the mechanical coupling means are active.
  • the second block is also driven.
  • the two blocks move as if they were integral, and the operation is comparable to that of a programmer provided with a single block of cams to control the totality of the organs.
  • the drive means drive the first block in the opposite direction. So the second block stays still. It is then possible, by continuing to control the first block so that it moves in the direction where the mechanical coupling means are not active, to make the organs controlled by the first block perform a certain number of tasks, independently of the organs ordered by the second block.
  • the programmer of the invention does not use a relay, but, in their place, contacts actuated by cams, of the conventional type, and the low cost and reliability of which are known.
  • means are provided for, in response to the direction of drive of said first block, prohibiting the supply of electrical members relative to the cams of said second block, when said first block is driven in the sense that said mechanical coupling means are active
  • the direction in which the two blocks move simultaneously is used only to bring the second block into a determined position, without inadvertent energization, causing noise and damage, of the organs normally controlled by the second block.
  • the first block is controlled in the opposite direction, which has the effect, on the one hand, of authorizing the supply of the members relating to the cams of the second block which must be put in service taking into account the position in which this second block is located, and on the other hand to have specific tasks executed by the members relating to the first block of cams.
  • - Said drive means comprise a two-way motor, an electronic control circuit of said motor, a disc integral in rotation with the output shaft of said motor and mechanical coupling means between said disc and said first block, providing a game
  • - Said means for prohibiting the supply comprise a part that can move in rotation or in translation over a first range of positions limited by two stops and coupled by friction to said disc, and a lever controlled by said movable part opening and closing an electrical switch for supplying said electrical members relative to the cams of said second block.
  • the device for preventing the supply of the organs relating to the second block mainly uses simple mechanical elements which give it a low cost price, good robustness and a reduced bulk.
  • said moving part is provided with coupling means with said disc, active over a second range of positions of said moving part, said second range being less than said first range and occupying its central part, so that after a change in the direction of movement of said disc, said moving part is driven by said disc, first under the effect of friction alone, then positively under the effect of said coupling means, and finally again under l effect of only friction.
  • the operation is particularly reliable, because over most of its travel, the moving part is positively driven by the disc, thanks to the coupling means, the friction being used only at the start and at the end of the race. , at the start of the stroke to make the coupling means active, and at the end of the stroke to stop making them active, in order to allow the disc to move while the moving part is in abutment.
  • said movable part is mechanically coupled with a clearance to a control part of said lever, so that when said movable part is driven by said disc under the effect of friction alone immediately after a change of direction of said disc , said control part remains stationary.
  • the force to be supplied by the control part is transferred to the mobile part when the latter is positively driven by the coupling means, and not when the latter is driven under the effect of friction alone.
  • the friction function is limited to a small movement of the moving part alone. As this is generally small and of negligible weight, the friction will always produce the expected effect, even after many hours of operation and the resulting wear.
  • said mechanical coupling means active in one direction comprise a pawl and a toothing with which said pawl cooperates.
  • said device is a washing machine provided with a drum and means for driving said rotating drum
  • said first block comprises cams cooperating with supply contacts of said means for driving the drum in rotation, to reverse the direction of said rotation.
  • the programmer of the invention is particularly useful in this case, since it allows great flexibility in programming the movements of the drum.

  • the terminal P is connected to a first movable stud of a double inverter 12, the four fixed studs of which are connected in pairs, and the second movable stud of which is connected to the inductor terminal 112.
  • the inductor terminal 113 is connected to terminal N by means of a triac 15 here.
  • Each rotor terminal 110 and 111 is respectively connected to one of the pairs of fixed studs connected to each other by the double inverter 12.
  • the members 21 a , 21 b , ..., 21 i , ..., 21 n here all have one terminal connected directly to a common connection 26, the other being connected to the terminal P via contacts 22 a , 22 b , ..., 22 i , ..., 22 n , respectively.
  • the contacts 22 a , 22 b , ..., 22 i , ..., 22 n are each provided with a fixed pad and a movable pad, to form switches.

  • Each switch 22 i makes it possible to supply, or not, and subject to the switch 25 being closed, the corresponding member 21 i .
  • the switch 25 allows the general cut-off of the supply of the plurality of members 21 a , 21 b , ..., 21 i , ... 21 n . If the switch 25 is open, no member 21 i will be supplied, even if the corresponding switch 22 i is closed.
  • An electronic circuit 40 connected between terminals N and P, controls a motor 41, here a two-way synchronous motor, as well as the triac 15.
  • the output shaft 410 of the motor 41 drives cams, not shown in FIG. 1, which exert on the movable studs of the double inverter 12 and switches 22 a , 22 b , ..., 22 i , .. ., 22 n of the forces shown diagrammatically by the arrows F.
  • the forces F act against restoring forces of the movable pads to move them and bring them into contact with the corresponding fixed pad.
  • the output shaft 410 of the motor 41 drives a disc whose direction of rotation controls, in a manner which will be better understood hereinafter, a lever which exerts on the movable pad of the switch 25 a force represented by the arrow F ′ to open or close it.
  • the programmer includes the electronic circuit 40, the motor 41, the double inverter 12, the switch 25 and the switches 22 a , 22 b , ..., 22 i , ..., 22 n of FIG. 1, as well as the cams and the opening device of the switch 25 which have been discussed, and which will now be described with reference to FIG. 2.
  • the first block 1 here comprises two cams 10 a and 10 b which respectively actuate each of the movable studs of the reverser 12, as well as a cam 10 c provided with a large number of teeth, which actuates a switch, not shown in a concern for simplicity, connected to a DC voltage to deliver to a microprocessor provided in the circuit 40, a signal in slots allowing, by counting the number of slots, determine the amplitude of the movement of the first block 1.
  • the microprocessor is also, not shown, connected to the connection 26, in order to constantly know the state of the switch 25, therefore the direction of movement of the disc 13, and therefore of the block 1. Thus the circuit 40 knows at any time the position of the cam blocks.
  • the second block 2 here comprises cams 20 a , 20 b , ..., 20 i , ..., 20 n which respectively actuate the movable pads of the switches 22 a , 22 b , ..., 22 i , .. 22 n .
