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 the drum drive 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 heating 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, and over only a first portion of the range of movement of said first block.
  • the drive means drive the first block in a back-and-forth movement which remains limited to the portion where the coupling means are active.
  • the second block being coupled to the first in only one direction, it is always driven in the same direction, and the operation is of the type of that of a programmer which would comprise only the second block of cams.
  • the drive means drive the first block outside the first portion. Then the second block remains stationary. It is then possible, by continuing to control the first block so that it does not leave the second, remaining portion of its range of movement, the second portion where there is no mechanical coupling between the blocks, to have the organs controlled by the first block a certain number of tasks, independently of the organs controlled by the second block.
  • the first portion of the range of movement on which the mechanical coupling is active will be relatively small, so that the second portion is relatively large, to leave the maximum of possibilities for the tasks to be controlled by the first block independently. of 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 prohibiting the supply of electrical components relating to the cams of said second block, when said first block moves inside said first portion.
  • the first block is controlled to leave the first portion, or active portion, which has the effect of firstly authorizing the supply of the members relating to the cams of the second block which must be put into service taking into account the position in which is this second block, and on the other hand to execute specific tasks to the organs relating to the first block of cams.
  • the first block returns to the active portion, which has the effect of prohibiting the supply of the members relating to the second block during the change of position of the second block.
  • the programmer of the invention is therefore particularly flexible to use, since it can be used with a block of cams memorizing the programs and moved step by step, or with a block of cams intended to be used with an electronic circuit which memorizes the different programs and which consequently controls the movements of the cam block, or even with a cam block which combines these two characteristics.
  • said means for preventing the supply comprise a cam and a switch actuated by this cam.
  • the device for prohibiting 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.
  • the second remaining portion of the range of movement of said first block, second portion for which said mechanical coupling means are active neither in one direction or the other is divided into a plurality of zones, each corresponding to a subroutine controllable by said first block.
  • means are provided for coding the position of said second block, and means for, in response to the coded position of said second block, determining the tasks to be controlled by the programmer.
  • said mechanical coupling means comprise a pawl secured to said first block, a toothing secured to said second block, and elastic means for biasing said pawl against said toothing when said first block moves on said first portion.
  • said apparatus is a washing machine provided with a drum and means for driving said rotating drum, and said first block comprises cams cooperating with supply contacts of said means 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.
  • This machine comprises, in known manner, a plurality of electrical components which are supplied with electrical energy selectively and sequentially, by means of a programmer, so as to carry out a washing program.
  • the washing machine thus comprises in particular a motor 11, of the universal type, for driving the drum in which the laundry is placed, and a resistor 7 for heating the water.

  • the program to be executed is a very simple washing program, which includes filling the machine with water, heating the water, and emptying the machine, these three phases being accompanied by rotational movements. in one direction and in the other, of the drum of the machine.
  • water intake solenoid valve and the drain pump are members 24 ′ controlled by block 2.
  • the circuit 40 first controls the triac 15 so that it remains open. The engine 11 is therefore stopped. It then controls the motor 41 to bring the block 1 to the position of FIG. 3 b where the block 2 is coupled to the block 1, in the direction T.

Naturally, there is provided in circuit 40 a memory in which the positions of the hollows and bumps of all the cams are stored. Because the general switch 16 is open and then prohibits the supply of the organs 24 ′, these cannot be inadvertently energized during these movements of the block 2.

It can control, via the circuit 40, the triac 15 to stop the engine 11, and move the block 1 to bring it into the sector ⁇ where the pawl 171 is active, and where the general switch 16 is open . The water intake is therefore stopped.
  • a series of back and forth movements of the block 1 is then commanded to bring the block 2 into a position where the cam 27 ⁇ has a hollow in the lever which controls the switch 27 ′.
  • the levers actuated by the cams 17 ⁇ and 27 ⁇ are integral with each other.
  • the switches 17 and 27 are always simultaneously in the same state. This is imposed for security reasons.
  • the switches 17 and 27 can only be closed if each of the two levers which actuate them is in a hollow of the corresponding cam 17 ⁇ or 27 ⁇ , since as soon as one of the levers is on a bump, it drives the other in the high position.
  • the microprocessor therefore leaves the block 2 in the position where the cam 27 ⁇ has a hollow in the associated lever, and moves the block 1 to bring it into an area where the cam 17 ⁇ has a hollow with the lever associated with it.
  • the water heating then begins.
  • this zone must be of sufficient amplitude to allow back and forth movements of the block 1 controlling the reversals of the direction of rotation of the drum during heating.
  • back and forth movements of different durations, for example, than they were during filling, this is perfectly possible.
  • the washing program can thus run until the end with, as has been pointed out, great flexibility in the control of the members 14 ′ capable of being controlled by the block 1 while the block 2 remains stationary.
  • the function of block 2 is on the one hand to control the organs such as the organs 24 ′, and on the other hand to indicate to the microprocessor of the circuit 40, via the absolute coding information on the binary inputs 23 ′, the tasks he must order.

  • Block 2 can also, as in the programmers of the prior art, be divided into a plurality of angular sectors each corresponding to a different program, the choice of one of these programs being made by moving block 2 to bring it at the start of the corresponding sector and the progress of this program being obtained by then sweeping this sector by block 2.
