Figure 1 schematically shows a part of the body or of a front 2 of an appliance (for example, oven or hob) and a device timer 4 according to the invention, by which it is possible to Manually adjust the time of day and operating time. The timer device 4 contains a control system with a button 6, by which it can be adjusted with a single button command 8 both the time of day and the operating time. He operating time may be the duration of operation, or according to another embodiment, the final hour of operation. He control system with a button 6 comprises a digital charger 10, indicated by a line of dashes and dots, which depending on the respective position of the control button 8 sends digital signals to an electronic control element 12 of the timer device 4 or generates them there.

The control system with a button 6 is of one type such that the control button 8 can be worn, applying a manual pressure force, from a first outer axial position 8-1, going through a second sunken axial position 8-2, to a third axial position pressed 8-3, which is located deeper than the second sunken axial position 8-2, where after release the manual pressure force, which is indicated schematically as an arrow of pressure direction 14, the control button 8 automatically returns to the second axial position 8-2 and stay there.

The control button 8 can then be pushed applying a new manual pressure force 14 from the second 8-2 axial position sunk to third position axial pressure 8-3, where when releasing the force of manual pressure 14, push button 8 returns automatically, through the sunken axial position 8-2, until the first outer axial position 8-1 and remains there.

The control button 8 can be turned at least the first outer axial position 8-1. I dont know it is, therefore, a simple push button or a key pressure but also of a rotary knob to adjust the different functions depending on the turning movement.

The timer device contains a means switching, which act in conjunction with the control button 8, to switch the timer device alternately to the function of setting the time of day or the setting function of the operating time, this switching being carried out automatically depending on the control button 8 being maintained, applying a manual pressure force 14, for a minimum time in the third position pressed 8-3, at least on one occasion or another when it reaches the third axial position pressed 8-3 in its axial movement path from the first outer position 8-1 and back to is. Depending on the function that has been adjusted in this way, you can then set the time of day or the time of operation, turning the control button 8 being in its first 8-1 axial outer position.

According to an embodiment preferred, a predetermined minimum time of, for example, a minimum of two seconds, preferably three seconds, during which it is necessary to manually maintain the control button 8 in the third axial position pressed 8-3, so that a switching of the function.

The functions are performed schematically in figure 1 by the fact that the control button 8 closes a 1F electrical contact, in the sunken axial position 8-2 closes another 2F electrical contact and in the axial position pressed 8-3, located below the above, close a third 3F electrical contact and because the section of command 12 allows to recognize which of these contacts is closed and how long the third 3F contact is closed in the indicated minimum time duration of, for example, 2 or 3 seconds. Each time the third 3F contact is closed, it acts in the command 12 a switch 18 on an electrical connection 20 which is associated with the function to set the time of day, or it is switched to an electrical contact 22 to which the function of adjustment of the operating time.

The turning angle zone of the control button 8 it is limited in both directions of rotation to two limit values default The control button 8 has a piece of drive 24, by means of which closes an electrical contact T4 upon reaching the final value in one of the directions of rotation and close another electrical contact T5 when reaching the final value in the other turning sense. The closure of one of the T4 electrical contacts causes a higher time value to be set and the closing of the another electrical contact causes a time value to be set less than the time or operating time, depending on the switch 18 has closed one or the other of the two connections Electrical 20-22. The corresponding time value It changes as long as the control button 8 is manually held in the corresponding final value of the direction of rotation. This technique already It is known in watches. According to another known technique, which can also be used alternatively in the present invention, the time value is modified, each time the value is reached end of the direction of rotation, only in a time step predetermined.

According to another embodiment that does not is represented instead, the angle of rotation can be detected and the direction of rotation of the control button 8 and as a result, adjust the time you want to adjust to a higher value or a lower value

A display device 30 (screen) of the Timer device 4 has positions for figures 32, 33, 34 and 35 to display the time. These same figures show alternatively the time of day or the operating time, depending on whether the function has been connected via the control button 8 for setting the time of day or the time setting function of functioning.

The display device 30 also carries a operating time symbol 36 and a time symbol day 38. The four positions of figures 32, 33, 34 and 35 are subdivided into two groups of two, among which there is a symbol of separation 40, for example, in the form of a double point. He separation symbol and the positions of the figures are without illuminate, illuminate or blink, depending on the function that is adjusted

According to the preferred embodiment, it is planned that switching from the function to adjust the operating time to function to adjust the time of day, is automatically canceled if within a timeout default, for example, 10 seconds, after this switching, no manual adjustment of the time of day is made on the control button 8.

The following describes possible functions.

First function I

"Set the time of day when you first put it on operation or after a power failure ", of according to figures 2, 3, 4 and 5

In figure 2, the control button 8 is located in its second sunken axial position: the positions of figures that they are at 0 and the time of day symbol flashes.

In figure 3 the button is pressed digital generator control 10 for a minimum time of, for example, 3 seconds, applying a manual pressure force 14, with which automatically connects the function to set the time of the day and with it the positions of the figures are put at a value of initial time of, for example, 12:00 and blink, just like The symbol of the time of day.

In figure 4, the control button 8 of the generator digital is in its first outer axial position, while that the 12:00 digit positions and the time of day symbol blink Now, if the control button 8 of the digital generator it is not rotated within a predetermined timeout of, for example, 10 seconds, then the switching to the operating state of figure 10, in which The duration of the operating time can be adjusted.

In figure 5, the control button 8 is turned in one of the senses of command, for example, to the right, until a stopper or an electrical contact such as, for example, the contact T4, whereby the digital generator causes the time to be set of the desired day, for example, 20:38 and because the positions of the figures 32, 33, 34 and 35 and the time of day symbol flash until the control button 8 of the digital generator is left manually sunk in the second sunken axial position.

Second function II

"Correction of the time of day"

In figure 6, the control button 8 of the generator digital is held tight manually pressed for time minimum of, for example, 3 seconds, applying a pressure force manual 14, whereby the current time of day, for example, 20:38 and the time of day symbol begin to flash.

In figure 7, the generator control button 8 digital is in its first outer axial position. Here the figures flash with the current time of day, for example, 20:38 and the symbol of the time of day. If the button is not turned on command 8 of the digital generator within a timeout default of, for example, 10 seconds, then appears in the display 30 the state of figure 10, that is, the function for Set the duration of the operating time.

Figure 8 shows the rotation of the control button 8 in one of the directions of rotation (clockwise rotation). In this way the new time of day is adjusted using the digital generator desired.

For this, the 32 digit positions flash, 33, 34 and 35 and the time of day symbol, until the control button 8 of the digital generator manually to the second sunken axial position.

Third function III

"Adjust the duration of the operating time"

In figure 9 the control button 8 of the generator digital is in its second sunken axial position. The time current of the day of, for example, 13:15 and the symbol of the time of day are permanently illuminated.

In figure 10, the control element 8 of the digital generator is in its first axial position Exterior. Through this adjustment of the digital generator have been set all positions of figures in the value 00:00 and blink at Same as the operating time symbol.

In figure 11, the control button 8 of the Digital generator is rotated in a direction of rotation (clockwise). From This mode adjusts the duration of the operating time. He Runtime symbol lights up permanently and the positions of the figures, which are also illuminated, show the respective current remaining time of the duration of the time of functioning. It is preferably a count to discount.

In figure 12, the control button 8 of the digital generator, after having adjusted The duration of the operating time. Thus, they are now the positions of the figures they indicate are permanently diluted the current time of day of, for example, 17:00 and the symbol of the Time of day and operating time symbol.

In figure 13, the control element 8 of the Digital generator is out. It is not sunk according to the figure 12. The operating time that was set is over. The number positions indicate 00:00 and are illuminated so permanent; the operating time symbol flashes; he home appliance, for example, an oven, disconnects automatically and preferably a signal is also generated acoustics, for example, a sound of, for example, three minutes.

In figure 14, the control element 8 of the digital generator has been manually sunk, having adjusted operating time duration according to the figure 11. The running time is over. They light up so permanent positions of figures with the current time of day, by Example 17:00 hours and the symbol of the time of day. The symbol of Operating time flashes. The appliance, by For example, an oven is automatically disconnected and preferably an acoustic signal is generated, for example, a sound with a duration of, for example, three minutes. Then you can follow the processes of figure 10 and figure 15.
