The equipment (1) has an energy storage device (3) that supplies a remote control receiver (4) in standby mode and a switch (5) that can be operated in standby mode that can close and/or open at least one contact pair in response to a control signal from the receiver or to mechanical operation of the switch. The switch causes a change between standby and on modes by easy manual operation of a first thrust rod acting on a stepping switch so that a first contact pair can be closed or opened depending on its current state. This can also be effected in response to a signal from the receiver to a magnetic coil in the stepping switch. The switch can be manually set to a further operating mode for complete isolation from the mains. An Independent claim is also included for a switch for the equipment.

Description

BEREITSCHAFTS"-Betrieb, und mit einem Schalter, der in einem ersten Betriebszustand betreibbar ist, in dem im Ansprechen auf ein Steuersignal des Fernbedienungsempfängers oder im Ansprechen auf eine mechanische Betätigung des Schalters mindestens ein Netzkontakt geschlossen oder geöffnet wird. Die Erfindung betrifft weiter einen Schalter für ein derartiges Gerät.The invention relates to a device, in particular a remote-controlled device for consumer electronics with a power supply device that can be operated at a mains voltage for supplying voltage to the device with an energy store for supplying a remote control receiver

"READY" operation, and with a switch which can be operated in a first operating state in which at least one mains contact is closed or opened in response to a control signal from the remote control receiver or in response to a mechanical actuation of the switch. The invention further relates to a switch for such a device.

Such a remote-controlled device is, for example a television or personal computer. Especially at It is common for televisions to be used for a long period of time to operate a so-called standby mode (= standby mode), in which only supplies certain components of the device with voltage become.

DE 44 19 581 A1 describes a device for the power supply of a remote-controlled consumer electronics device in standby mode known. The remote control receiver is connected via a Energy storage which is designed as a solar panel operated. During the Standby operation of the television receiver is therefore only the Remote control receiver and an evaluation circuit supplied with energy, while all other components of the television receiver in this Operating state do not consume any energy.

The invention has for its object to provide a device that with little effort and without sacrificing comfort in terms of remote control STANDBY "operation without power consumption from the grid.

This object is achieved in a device of the type mentioned in that the switch can be operated in an operating state in which a change between READY "operation and ON "state by lightly manual actuation of a first push rod acting on the advance switch is brought about by the fact that when the mains contact is open, the mains contact is closed and when the mains contact is closed, the mains contact is opened and closed in response to one from the remote control receiver the solenoid of the advance switch available control command can take place.

To achieve the READY "operation, it is only necessary to open a network contact pair a short distance. This is done by means of a first push rod, which acts on the advance switch. All that is required is a small amount of energy to move the contact spring of the network contact pair to be opened. If this contact is open, the device is in the READY "operation and neither active nor reactive power is taken from the supply network. The voltage supply of the remote control receiver in the "READY" operation takes place by means of an energy store, for example a battery, an accumulator or a special capacitor. In the event that the energy store, for example, as a result of a long period of time READY "operation should no longer have sufficient energy to close the contact pair, is by manual actuation of the switch, ie the first push rod acting on the advance switch, a switching on, ie ensuring the ON "state again possible.

Complete network separation and therefore a real one OFF "state can be ensured that the switch can be brought manually into a further operating state for complete mains separation, in which the power supply device that can be operated with mains voltage is completely separated from the mains voltage. In this state, both mains contact pairs are open and the device is also open Remote control receiver cannot be switched on again.

An advantageous embodiment in which the switch in both Positions no energy required results from the fact that the switch as two-pole switch is formed and one by means of an actuating lever and has a switch which can be actuated by means of a magnetic coil, which opening and closing of at least one network contact.

The energy consumption in READY "operation can be further reduced in that the device has an operating voltage display, which is only for displaying the A "state is provided in which the first and second network contacts are closed and that in STANDBY "operation no display device is provided.

This further increases the energy consumption for the remote control receiver reduces the remote control receiver in a power saving mode can be operated by simply evaluating whether a Remote command is present or not, however, upon detection of any Remote control command of the remote control receiver from energy saving mode is switchable into an operating mode in which a complete Command evaluation of the recognized remote control command takes place, with Detection of a device intended for the remote-controlled device Remote control command of the network contact or the network contacts of the switch is or will be switched on and if one is not recognized for the device certain remote control command of the remote control receiver in the Energy saving mode is switched.

Of the OFF "state can be switched by means of the switch, which is also used to switch between ON "and READY "is provided, that the switch to achieve the OFF "state, both manual contacts open due to manual operation of the lever.

In the following, the invention is illustrated by the figures Exemplary embodiments explained and described in more detail.

1 shows a block diagram of a remotely controllable television set 1 are for the sake of clarity only those for the function of the Invention required components shown. The television set 1 has one Power supply device 2 for supplying the television set 1, a Signal processing device 9 and a screen 10. Furthermore is a remote control receiver 4, an energy storage 3, a Operating voltage display 7 and a switch 5 are provided. The switch 5 is connected on the input side to network contacts of a plug 12, while On the output side, connecting line 2a, 2b to power supply device 2 to lead. The plug 12 is used to contact a socket 13. Die Actuation or control of the switch 5 is carried out either via a Control line 8 of the remote control receiver 4 or mechanically via a Mechanical actuation device 14 of the switch 5 indicated as an arrow. The remote control receiver 4 is intended for remote control commands a remote control transmitter 11 to receive and detect.

The central element of the remote-controllable television set 1 shown in FIG. 1 is the two-pole switch 5, which can be changed in the operating states both via the control line 8 of the remote control receiver 4 and via a mechanical actuation device 14. The switch 5, in particular designed as a two-pole switch, can assume three operating states. The first operating state is that both contact pairs 6a / 37, 6b / 38 are open. This corresponds to a complete network separation and characterizes the so-called OFF "state. The second operating state characterizes the so-called In this operating state, the first contact pair 6a / 37 is open, while the second contact pair 6b / 38 is closed. In this operating state, the closing or the reopening of this opened contact pair 6a / 37 can be carried out either with the aid of the control line 8 and of the signal transmitted thereby or with the aid of a mechanical actuation of the switch 5. As will be explained in detail in connection with Fig. 4, the switch 5 includes an incremental switch 35, which has two stable operating states. In the first state, a pair of contacts is open while The third operating state of the switch 5 is characterized in that both pairs of contacts 6a / 37, 6b / 38 are closed, in which case the television set 1 is in operation and this ON "state is signaled by the operating voltage display 7.

2a to 2c again show in detail the different operating states of the switch 5. In FIG. 2a, the OFF "state. In this operating state, the two contact pairs 6a / 37, 6b / 38 are open, there is complete disconnection from the plug 12. FIG. 2b shows the READY "state when the contact pair 6a / 37 is open while the contact pair 6b / 38 is closed. The third operating state is In this operating state, both contact pairs 6a / 37, 6b / 38 are closed. There is a connection between the plug 12 and the connecting lines 2a, 2b which feed the television set 1.

Fig. 3 shows a circuitry embodiment of a power supply of a device. The ones already in connection with FIG. 1 introduced reference numerals used. Likewise, only those for Invention essential components shown. So the device has one Power supply device 2, a switch 5, a line filter 15, a Demagnetization circuit 16, a rectifier circuit 17 with downstream capacitor 18, one from a microcomputer 4b and an infrared receiver 4a existing remote control receiver 4, one Energy storage 3, and an operating voltage display 7 and one Control transistor 19 on. Furthermore, a step-up converter 40 and a Capacitor 41 is provided.

The remaining circuit components shown in FIG. 3 are not specified for reasons of clarity.

With regard to the basic function, reference is made to FIG. 1 in order to avoid repetitions. The infrared receiver 4a, the microcomputer 4b and the energy store 3 are all located on the secondary side (cold side, mains-separated side) of the television set 1. In the standby mode, also referred to as standby mode, the television set 1 becomes the infrared receiver 4a and the microprocessor 4b Energy storage 3 supplied. A corresponding infrared command triggers the closing of the contact pair 6a / 37 via the control line 8, the device starts up and the energy store 3 is in turn charged via the secondary side. So that in READY "operation takes as little energy as possible from the energy store 3, an infrared receiver 4a is used, which has a so-called low-energy consumption mode. This is an infrared receiver 4a, which can be operated in a mode with only a limited detection. This leads to The greatly reduced detection detects all incoming infrared signals without differentiating. If a signal arrives, the infrared receiver 4a switches to the nominal operation with higher power consumption, in which a complete detection of the infrared commands takes place. The microcomputer provided for the standby operation 4b can now decode the infrared signals, and if this detection reveals that the received infrared signal is a signal that is foreign to the system, the infrared receiver 4a falls back into energy-saving mode device 1 is switched on. The energy store 3 can be a battery, a rechargeable battery or, for example, a so-called gold CAP. If the device 1 at regular intervals in the ON "state and the energy storage 3 is recharged and thus it is possible to switch on the device 1 at any time via the remote control and the remote control receiver 4. Only in the event that the device 1 is in use for a longer period of time READY "operation remains, it may be possible that the energy store 3 is discharged. The switch 5 is designed so that the device 1 can be put back into operation by lightly pressing the push button 20 of the switch 5. This is due to the Reference numeral 14 and the corresponding arrow in Fig. 3. Contrary to the practice in previously implemented television sets, the device does not have a so-called "standby display". This is because even a light-emitting diode in the READY "operation would consume too much energy and would quickly discharge the energy store 3. Only for the display of the An "operating voltage display 7" is provided. The mechanical actuation device 14 also mechanically completely switches off, ie opening both contact pairs 6a / 37, 6b / 38 is possible, as does switching back on again "REISTSCHAFTS" company or from READY "operation in the A condition.

The one optionally available in FIG. 3, for example as a swiched capacitor trained step-up converter 40 generates from the energy storage device 3 supplied voltage of for example 5 volts a higher voltage of for example 10-12 volts. This higher voltage serves as a safe one Actuation of the coil 26 (cf. FIG. 4) of the advance switch via the capacitor 41. The higher voltage at the output of the step-up converter 40 has the Advantage that a second voltage, for example, to generate a higher voltage further energy storage devices connected in series can be saved. Of the Boost converter 40 is e.g. fed from the energy storage 3 and at Required activated by the microcomputer 4b, while otherwise in the Is idle and consumes only a few microamps.

Fig. 4a shows a schematic diagram of a switch 5, as in Relation to the exemplary embodiments shown in FIGS. 1-3 can be used. The switch 5 consists of a housing part 5a, in which the essential mechanical and electrical components are arranged and from a push button 20, for example in the Front of a television is visible and operable and arranged with With the help of which the television can be switched on or off. Of the Push button 20 is via a first push rod 28 and a second Push rod 29 with the mechanical and electrical components of the Housing part 5a of the switch 5 coupled. The push rod 28 is with the Push button 20 is not fixed, but is movably mounted in it. The Push rod 29, however, is fixed with the push button 20. The first push rod 28 acts on the advance switch via a linkage 33, 34 35, which is rotatably mounted in a fulcrum 36. In the housing part 5a Switch 5 is also a coil 26 and one with the second Push rod 29 provided in connection lever arm 22. Of the Lever arm 22 is movably mounted on the axis of rotation 23. The switch 5 has two due to the two push rods 28, 29 mechanical actuation options. The first mechanical Actuation option is that the push button 20 is only one short distance is operated. The first push rod 28 is in operation and the advance switch 35 moves for example by 45 °, whereby opening and closing of the contact pair 6a / 37 is effected. Here, the shape of the advance switch 35 as Lever wheel, the contact spring 6a by the incremental switch 35 laterally from that fixed contact 37 pushed away, whereby the power supply through the Network, according to Fig. 2b, or Fig. 2c is interrupted or closed.

In addition to the first mechanical with the help of the push button 20 Actuation of the advance switch 35 there is also the possibility of To advance switch 35 also electrically by means of the solenoid 26. Here, the opening and closing of the first pair of contacts 6a / 37 in the manner described above, but with the movement of the incrementer 35 by the magnetic attraction force acting on the linkage 33 the solenoid 26 takes place. The linkage 33 is naturally magnetic or magnetizable.

This takes place in response to a control command which is given via the control line 8 (cf. FIGS. 1 to 3), which causes the solenoid 26 to actuate the advance switch 35 via the linkage 33, 34. By means of this first mechanical actuation or by means of the described electrical actuation of the first contact pair 6a / 37, this contact is opened or closed, which means a change between the operating state A "and the The second contact pair 6b / 38 (see FIG. 4b) behind / under the first contact pair 6a / 37 is always closed in these two operating states. The opening and closing of only one contact pair also results in a small amount of energy needed to move the contact spring 6a.

The second mechanical actuation option for the switch 5 is a mechanical actuation of the push button 20 in such a way that the Push button 20 a long distance in the direction of the housing part 5a is pressed. This is due to the pressure of the push rod 29 on the Lever arm 22 for a lifting movement of the lever arm 22 about its axis of rotation 23 and to mechanically push away both the contact spring 6a and also to push away the back / under the contact spring 6a Contact spring 6b.

The push rod 29 is designed such that when the push button 20 is short, the push rod 29 does not yet touch or push the lever arm 22, but the push rod 28 already acts on the linkage 33 in the manner described above. The push rod 29 has a mechanical idle on this distance. Only after this mechanical idling has been overcome does the push rod 29 act on the lever arm 22 in the manner described above.
The spring 21, which is mechanically connected to the first push rod 28, serves to ensure that from a certain mechanical path, the mechanical idling of the second push rod 29, the first push rod 28 no longer acts mechanically into the housing part 5a, but into the push button 20 moved in and no longer acts on the linkage 33. At the same time, the second push rod 29 travels a longer mechanical path in the switch 5. The spring 21 is selected in its spring force such that it exceeds the counterforce of the return spring 27 and the contact spring 6a.

By operating the push button 20 with a larger stroke, which acts on the second push rod 29, the complete state of the Device 1 ensured. In this operating state there is a complete Disconnection. With the help of a lock, a so-called overstroke, which is not specifically shown in FIGS. 4a to 4d is the switch 5 or the push button 20 securely locked in the respective positions and again detachable from the lock. 4b shows the switch 5 in a side view with respect to a section line C (see FIG. 4a) while FIGS. 4c and 4d den Show switch 5 in a perspective view.
