  00 --._ .. i. t N oLD Sale of booklets to IMPRIMERIE NATIONALE. 27. rue de le Convention 75732 PARIS CEDEX 15 The subject of the invention is a programmer for household appliances, in particular for washing machines or dryers, comprising a programming drum, comprising a reversing drum and an electromagnetic operating device (device "Thermostop"), in which the programming drum, controlled by an electromagnet, is prevented from switching when it carries out a program step, and is authorized to switch when a set value is reached, also comprising a delay device which has a maneuvering and counting wheel, which is maneuvered by the reversing drum, when a transmission lever controlled by the programming drum is activated, an operating cam authorizing the switching of the programming drum, after a

defined number of steps.

  A programmer of this type is described in DE-OS 36 21 906. This device makes it possible to easily extend, in a particular case, at least one duration of a chosen program, the switching on and off of the programming drum using the same device elements for the operation with "Thermostop", as for an extension of the duration of the steps. The user has the possibility of selecting a washing program, and in a particular case, of prolonging at least one duration of this program compared to the normal case, by actuating an additional command. If you have, for example, laundry which must be washed in a normal program, but which is particularly dirty, the user starts the normal program and also activates the

  key that extends the cycle times.

  The time delay device according to DE-OS 36 21 906 is suitable for large caliber programmers. For more compact types of programmers, this device is only suitable under certain conditions. The maneuvering and counting wheel according to DE-OS 36 21 90 is mounted concentric with respect to the axis of the programming drum. It only has maneuvering teeth on part of its periphery. Another part of the periphery is occupied by snap lugs. To recall the maneuvering and counting wheel, a tension spring is provided against the force of which the reversing drum

must work.

  In addition, a cursor, driven by the electromagnet, and which cooperates with a wiper, is arranged on the periphery. For small radii of the programming drum, this configuration is not

practically not possible.

  The object of the invention is to propose a programmer of the aforementioned type in which at least one cycle duration of the chosen program can be extended if necessary, in a simple manner, in which the programming drum is switched on and off. means of the same device, for operation with "Thermostop" as for an extension of the duration of the steps, and in which the timing device is no longer linked in its construction, to the radius of the programming drum, and which nevertheless allows to get a long time

time delay.

  This object is achieved with a programmer of the aforementioned type according to the invention in that a first lever, actuated by the electromagnet, is coupled with a second lever so that it is driven by the first lever, in the event of excitation of the electromagnet, and prevents switching of the programming drum, and authorizes its switching, only after a defined number of operating steps, independently of the first lever, in that the operating and counting wheel is eccentric rise with respect to the programming drum, and is provided with maneuvering teeth, over almost its entire periphery, and in that at the latest after a complete rotation of the maneuvering and counting wheel, the second lever is urged to the

  switching of the programming drum.

  The device according to the invention can also be used for compact construction programmers, since the maneuvering and counting wheel and the levers can have a shape which does not depend on the radius of the programming drum. Due to the fact that maneuvering teeth can be provided around the entire circumference of the maneuvering and counting wheel, delay times can be obtained

relatively long.

  That it is possible to obtain, with the same constituent elements, not only a long delay time, but also shorter delay times, also constitutes an advantage for

special applications.

  Another advantage lies in the fact that the reversing drum controlling the maneuvering and counting wheel must not operate against a return spring of the maneuvering wheel and

  counting, opposed to its displacement.

  In addition, obtaining the initial or rest position of the maneuvering and counting wheel is simplified. This is achieved by itself, when the maneuvering and counting wheel has

performed a full rotation.

  If you do not wish to modify the duration of

  not, the chosen program runs regularly.

  For defined program steps, the electromagnetic switching device ("Thermostop" device) interrupts the progress of the program, until the set temperature is reached. If it is desired to extend the duration of the steps, the timing device acts in at least one program step. It stops the program drum program progressing, until the maneuvering and counting wheel authorizes the switching of the programming drum again. For this or these program steps, we therefore do not work with the cycle time provided on the programming drum, but with a longer cycle time. The maneuverability of the timing device, by means of a manual control or a sensor, is simplified by the simultaneous use of the electromagnetic switching device which is provided anyway. Indeed, with a contact to be actuated by means of a manual control or the sensor, the electromagnet can be excited so as to maintain or deactivate the programming drum, for a step of

planned program.

  To deactivate the programming drum, the second lever is actuated by the electromagnet, via the first lever; and what one is in operation with "Thermostop", or that an extension of the duration

be scheduled.

  To turn on the programming drum, after extending the duration of the

26Z8889

  step, the second lever pivots independently. from the first. To energize the programming drum after operating with "Thermostop", the first lever pivots and thus drives the second lever. In addition to or in place of the manual control or the sensor, the delay device can be activated by an operating contact which is controlled

  by the programming drum itself.

examples of realization.

  A programmer for a washing machine has a reversing drum 1 with a spindle 2 and a drive gear 3. A programming drum 4 is mounted on the same axis as the reversing drum 1. The programming drum 4 is provided with '' a drive gear 5 and in addition to the cam disks, a control contour 6. The drive teeth 3 of the reversing drum 1 and the drive teeth 5 of the programming drum 4 are

  driven by a transport pawl 7.

  A "Thermostop" device (electromagnetic switching device) is associated with the programming drum 4. It operates with an electromagnet 8 which is electrically connected in series with a first operating contact 9, actuated by means of a cam disc of the drum programming

  4, and a thermostat contact 10 (see Figure 14).

  A first lever 11 is mechanically coupled to the electromagnet 8. For this purpose, a stirrup 12 on which a pusher 13 of the electromagnet 8 acts, is formed on the first lever 11. The first lever 11 is pivotally mounted on an axis 14 which is arranged eccentric to the axis 15 of the drum

  inverter 11 or programming drum 4, that is

  to say that it does not coincide with this one. On the

  first lever 11 acts a tension spring 16.

  A second lever 17 is mounted on the axis 14. This lever is coupled to the first lever 11 by a pressure spring 18. The lever 17 includes a wiper 19 which is associated with a rocker 20 which

  rotates with the programming drum 4.

  The programmer has a lever.

  transmission 21 which can pivot around an axis 22.

  A first arm 23 of the transmission lever 21 is provided with a feeler tip 24 which senses the control contour 6. The first arm 23 is pressed against the control contour 6, by a pressure spring 25. The transmission lever 21 is further provided

a second arm 26.

  In the two exemplary embodiments according to FIGS. 1 to 7, a maneuvering and counting wheel 27 is rotatably mounted at the free end of the second arm 26 of the transmission lever 21. The maneuvering and counting wheel 27 is present everywhere its periphery, maneuvering teeth 28 which are associated with the spindle 2. The maneuvering and counting wheel 27 is provided with a heart curve 29 to

  which is associated with a fixed stop 30.

  In the embodiment of Figures 1 to 4, the tip of the heart curve 29 forms an actuating cam 31 for the second lever 17. A stopper 32 is associated with the actuating wheel and

counting 27.

  In the embodiment of Figures 5 to 7, the operating cam 31 for the second lever 17 is formed on the second arm 26. One of the operating teeth 28, namely the operating tooth 33, is narrower than the other maneuvering teeth 28. The stopper 32 has a slot 34 into which can only fall the maneuvering tooth 33 narrow. In the embodiment of Figures 8 to 13, the maneuvering and counting wheel 27 is mounted fixed, eccentric with respect to the axis 15. The spindle 2 is formed by an impulse tooth. On the heart curve 29 is applied a lever 36 biased by a spring 35. The maneuvering cam 31 is formed on the side opposite to the heart curve 29, of the maneuvering and counting wheel 27. The free end of the second arm 26 forms the stopper 32. The stopper 32 has a shape such that it can, on the one hand, engage between two operating teeth 28 (see FIGS. 9, 10) and on the other hand apart from the fact that a high operating tooth 39 can come into abutment against it (see FIG. 11) this tooth being higher than the other operating teeth 28. The control contour 6 has a medium level 44 and a high level 45. If the feeler tip 24 is located at the middle level 44 (see FIG. 11), the stopper 32 is located at a place such that it forms a stop for the upper operating tooth 39. If the probe tip 24 is at the high level (see FIG. 12), the stopper 32 is located outside the trajectory of the operating tooth.

high 39.

  In the embodiment of Figures 8 to 13, there is provided, in addition to the fixed spindle 2, a controlled spindle which is pressed, by means of a spring 42, against a time control contour 41 of the programming drum 4 , and who feels it (see figure 13). We can thus order another duration

extended time.

  An operating contact 37 is provided which can be controlled at the same time as the transmission lever 21, and which is electrically connected in series with a manual control contact or a sensor contact 38. This series connection is parallel to the connection in series of contacts 9,10 (see figure 14). This assembly is the same for all the examples of realization. The washing machine has a manual control (not shown) for actuating the operating contact 38. Instead of the

  manual control, it is also possible to provide a sensor.

  This detects for example the degree of clogging of the washing water and closes the operating contact 38 when the water is very cloudy. This automatically extends the washing steps of the

  respective program, planned for extension.

  Another operating contact 43 can be mounted

  in parallel with the serial connection of the contacts 9,10.

  This operating contact is controlled by the programming drum 4. Closing it can initiate an extension of the step duration by one program step, independently of the operating contacts 37, 38. If one does not wish to have this possibility, the operating contact 43 is deleted. If the manual control or the sensor is not provided, the operating contacts 37, 38 are deleted. In this case, the operating contact 43 controls alone

  one or more extensions of the duration of the steps.

  The operation of the exemplary embodiment according to FIGS. 1 to 4 is as follows: As long as the manual control is not actuated, that is to say as long as the operating contact 38 is open, only the device operates to "Thermostop". If the operating contact 9, controlled by a cam disc is closed, and if the operating contact 10 is also closed, because the set temperature has not yet been reached, the electromagnet 8 is activated. The first lever 1 thus pivots against the force of the spring 16, in the direction of the arrow E. Via the pressure spring 18, the second lever 17 also pivots, so that the wiper (19) which is associated with it, reaches under the latch 20. The latter thus closes an entrentent of the drive toothing 5 of the programming drum 4, so that the transport pawl 5 cannot fall into this entredent, and the drum programming 4 cannot continue switching. It is only when the set temperature is reached, and therefore the operating contact 10 opens, that the electromagnet 8 is no longer energized, so that the tension spring 16 replaces the first lever 11 in its initial position. The second lever 17 follows this movement, the wiper 19 leaving the rocker 20, so that the latter releases the relevant intermediate from the drive toothing 5, and the programming drum 4 can continue to switch by means of the pawl 7. This is the initial position

shown in Figure 2.

  In the initial position, the feeler tip 24 rests on the large circle surrounding the control contour 6, so that the transmission lever 21 is held so that the maneuvering teeth 28 of the maneuvering and counting wheel 27 are located at outside the path of the spindle 2. The maneuvering and counting wheel 27 therefore does not move during the rotation of the reversing drum 1. The flat part of the heart curve 29 is applied against it the stop 30, so that the zero position (initial position) of the maneuvering and counting wheel 27

is assured.

  If the operating contact 38 is closed to extend a cycle time, the feeler tip 24 falls into a slot 6 'of the control contour 6, for a defined position of rotation of the programming drum 4. It follows that the second arm 26 also pivots, so that one of the maneuvering teeth 28 of the maneuvering and counting wheel 27 comes into abutment against the stopper 32 (see FIG. 3). At the same time, the operating contact 37 closes. It follows that the electromagnet 8 is excited, so that the first lever 11 pivots in the direction of the arrow E, thus driving the second lever 17, by means of the pressure springs 18. The wiper 19 thus passes under scale 20 and raises it, so that it blocks

  the relevant entry of the drive teeth 5.

  The programming drum 4 thus remains stationary.

  During the next rotation of the reversing drum 1, in the direction of arrow F, the spindle 2 reaches one of the operating teeth 28. The operating and counting wheel 27 thus rotates one step. At each rotation of the reversing drum 1, the maneuvering and counting wheel 27 thus rotates another step, at the same time as the heart curve 29 which

is associated.

  Following the continuous switching of the maneuvering and counting wheel 27, the maneuvering cam 31, formed on the heart curve 29, reaches a

  heel 17 'of the second lever 17 (see FIG. 4).

  The latter thus pivots in the direction of the arrow G. The wiper 19 then leaves the rocker 20, which thus releases the entry from the drive teeth 5. The programming drum 4 can then continue to switch. As the programming drum 4 switches, the feeler tip 24 is raised by the edge of the slot 6 'of the control contour 6, on the large periphery of the control contour 6. As a result, the contact maneuver 37 opens and the second arm 26 pivots so that the maneuvering and counting wheel 27 passes, in the direction of arrow H, of the path of the spindle 2, in its initial position. The heart curve 29 thus reaches the stop 30. As a general rule, the maneuvering and counting wheel 27 remains in a position such that the flat part of the heart curve 29 is in contact with the stop 30. If the wheel maneuvering and counting 27 rotates relative thereto, the cooperation of the heart curve 29 and the stop 30 causes the maneuvering and counting wheel 27 to pass into its zero position. Obtaining the zero position requires no force from the drive of the reversing drum 1 or the programming drum 4. The maneuvering and counting wheel 27 only turns when it exerts its function of prolonging the

duration of steps.

  The extension of the duration of the steps which can be obtained is approximately equal to the product of the number of actuating teeth 28 of the actuating and counting wheel 27, by the time during

  which the reversing drum 1 rotates 360.

  On the reversing drum 1, it is also possible to provide more than one time zone 2. This allows a shorter extension of the duration of the steps. If two time zones 2 are provided for example, the maneuvering and counting wheel 27 is switched by two maneuvering teeth 28, each time the drum is rotated

inverter 1.

  The operation of the exemplary embodiment according to FIGS. 5 and 6 is practically similar to that of the exemplary embodiment according to FIGS. 1 to 4. It will only be described below insofar as it differs from the example of embodiment of the figures

1 to 4.

  If the arm 26 pivots opposite the direction of the arrow H, one of the operating teeth 8 reaches the stop 32. The operating cam 31 of the second arm 26 does not act on the second lever 17 (see Figure 6). The maneuvering and counting wheel 27 is switched by the spindle 2, until its narrow maneuvering tooth 33 falls into the slot 34 (see FIG. 7). The operating cam 31 reaches

  so on the second lever 17, so that this

  ci rotates in the opposite direction to that of arrow F,

  so that the wiper 19 leaves the rocker 20.

  The operation of the exemplary embodiment according to FIGS. 8 to 13 essentially corresponds to that of the exemplary embodiments described. It is explained below only insofar as it deviates

  examples of embodiments described.

  The maneuvering and counting wheel 27 is fixed.

  Consequently, the spindle 2 encounters one of the maneuvering teeth 28 of the maneuvering and counting wheel 27, at each rotation. The lever 36 which is applied against the heart curve 29, automatically recalls the maneuvering and counting wheel 27, after each rotation of the reversing drum 1, as long as the second arm 26 does not engage between

two operating teeth 28.

  If the feeler tip 24 falls into a slot 6 'of the control contour 6, the second arm 26 pivots between two maneuvering teeth 28. The maneuvering and counting wheel 27 is locked so that it can no longer be recalled by the lever 36. With each rotation of the reversing drum 1, the maneuvering and counting wheel 27 continues to rotate one step (see FIG. 9). As mentioned above, the lever 17 pivots so that its wiper 19 maintains the rocker 20 in front

  the relevant input of the programming drum 4.

  At the end of the switching of the maneuvering and counting wheel 27, the maneuvering cam 31

  reaches the second lever 17 (see Figure 10).

  This therefore pivots in the opposite direction to that of arrow F, so that the rocker 20 is released and that the programming drum 4 can continue to rotate under the effect of the transport pawl 7. It ensues that the second arm 26 is completely distant from the maneuvering and counting wheel 27, in the direction of the arrow H, when the feeler tip 24 is raised to the high level 45. Because it is applied against the curve in core 29, the lever 36 then recalls the maneuvering and counting wheel 27 in its zero position (see FIG. 12). If the feeler tip 24 is not raised to the high level 45, but only to the medium level 44, the stopper 32 pivots so as to release the maneuvering teeth 28, but remains in the path of the maneuvering tooth 39 high. The maneuvering and counting wheel 27 is only recalled until the high tooth 39 comes into abutment against the stopper 32 (see FIG. 11). The following extension of the duration of the steps is therefore shorter., In accordance with the position of the upper operating tooth 39, around the circumference of the wheel.

maneuvering and counting 27.

  Between two maneuvering teeth 28, there is an enlarged intermedent 46, for the actuating cam 31. This intermedent is used for the time zone 2 or 40 to pass in front of the actuating and counting wheel 27, without causing it to switch again immediately, when the operating cam 31 is on the second lever 17. If the controlled spindle 40 is pushed so as to act on the operating teeth 28, the extension of the duration of the steps is shortened compared to the case in which the spindle 40 is set back so as not to be in contact with the operating teeth

28.

  In the embodiments described, the control contour 6 against which the transmission lever 21 or its feeler tip 24 is applied, is directly provided on the programming drum

  4. The control contour 6 can however be formed.

  also on a time extension ring, driven

with the programming drum 4.

  The various characteristics of the described exemplary embodiments can also be combined. For all the exemplary embodiments, it is possible to provide several time zones 12 or 40 controlled or not controlled by the programming drum 4. The controlled time zone (s) can also be controlled by a timer ring, driven by the drum

programming 4.

  For the device described, and if the operating contact 43 is used, it is also possible to make time extension steps of different lengths, the control of which depends solely on the position of the

programming drum 4.
