Abstract

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

The invention relates to a device, in particular a remote-controlled device of Consumer electronics with a mains voltage operable Power supply device for powering the device with a Energy storage for supplying a remote control receiver in "STANDBY" operation, and with a switch in a first Operational state is operable in which in response to a control signal of the Remote control receiver or in response to a mechanical Actuation of the switch at least one mains contact closed or is opened. The invention further relates to a switch for such a Device.

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

From DE 44 19 581 A1 discloses a device for powering a remote-controlled consumer electronics device in standby mode known. In this case, the remote control receiver via a Energy storage is designed as a solar panel operated. During the Standby mode of the television receiver are thus only the Remote control receiver and an evaluation circuit powered; while all the other components of the television receiver in this Operating state do not consume energy.

The invention has for its object to provide a device that with little effort and no loss of comfort in terms of one Fembedienbarkeit a "STANDBY" operation without power consumption off the power grid allows.

This object is characterized in a device of the type mentioned by solved that the switch is operable in an operating state, in which a change between "STANDBY" mode and "ON" state easy manual actuation of a first acting on the continuation switch Push rod is caused by that when the power contact is open Close and with closed mains contact an opening of the net contact takes place, wherein the opening and closing of the network contact also in response on one of the remote control receiver to the solenoid of the Programmer deliverable control command can be made.

To achieve the "STANDBY" operation, it is merely necessary to open a net contact pair to a small distance. This takes place by means of a first push rod, which acts on the continuation switch. Therefor is only a small amount of energy needed to contact the spring of to move the opening power contact pair. If this contact is open, the device is in "STANDBY" mode and neither active nor Reactive power is absorbed from the supply network. The Power supply of the remote control receiver in "STANDBY" operation is by means of an energy store, For example, a battery, a rechargeable battery or a special Capacitor. In the event that the energy storage, for example, in succession a long "STANDBY" operation no longer provides enough energy to Closing the contact pair should be available through a manually operating the switch, i. the one acting on the continuation switch first push rod a turn on, i. a guarantee of the "ON" state again possible.

A complete network separation and thus a true "OFF" state can be ensured that the switch manually to complete Network separation in another operating state can be brought, in which the Mains voltage operable power supply completely from the Mains voltage is disconnected. In this state, both are mains contact pairs open and the device is not even by remote control receiver again switched on.

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 As well as by means of a solenoid actuated forward switch, which causes the opening and closing of at least one network contact.

The energy consumption in the "STANDBY" mode can thereby continue be reduced, that the device has an operating voltage display, the is provided only to indicate the "ON" state, in the first and second mains contact are closed and that in the "STANDBY" mode no display device is provided.

The energy consumption for the remote control receiver is thereby further reduces the remote control receiver in a power saving mode is operable in which only an evaluation is made, whether a Remote control command is present or not, wherein upon detection of any Remote control command the remote control receiver from the power saving mode is switchable to an operating mode in which a full Command evaluation of the detected remote control command takes place, with at Detection of a remote-controlled device Remote control command the mains contact or the mains contacts of the switch is turned on and / or when detecting one for the device is not certain remote control command the remote control receiver in the Energy saving mode is switched.

The "OFF" state can be controlled by means of the switch, which also for the change between "ON" and "STANDBY" is provided, take place in that the switch to achieve the "OFF" state by stronger manual Actuate the lever causes an opening of both power contacts.

In the following the invention will be described with reference to the figures Embodiments explained and described in detail.

Fig. 1 shows a block diagram of a remotely controllable TV 1. Dabei For the sake of clarity, only those for the function of Invention required components shown. The TV 1 has a Power supply device 2 for supplying the TV 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 is provided. The switch 5 is the input side connected to power contacts of a plug 12 while on the output side connecting line 2a, 2b to the power supply device. 2 to lead. The plug 12 is used to make contact with a socket 13. Die Actuation or control of the switch 5 takes place either via a Control line 8 of the remote control receiver 4 or mechanically via a indicated as an arrow mechanical actuator 14 of the switch. 5 The remote control receiver 4 is provided for remote control commands a remote control transmitter 11 to receive and detect.

Central element of the remote-controlled television 1 shown in FIG. 1 is the two-pole switch 5, both via the control line 8 of the Remote control receiver 4, as well as a mechanical Actuator 14 is changeable in the operating states. Of the Switch 5, in particular designed as a two-pole switch, can be three Occupy operating conditions. The first operating state is that both contact pairs 6a / 37, 6b / 38 are open. This corresponds to a complete one Grid disconnection and identifies the so-called "OFF" state. The second Operating state indicates the so-called "STANDBY" operation. In this operating state, the first contact pair 6a / 37 is opened while the second contact pair 6b / 38 is closed. The closing or the renewed Opening this opened contact pair 6a / 37 can in this operating condition either by means of the control line 8 and the signal transmitted thereby or by means of a mechanical actuation of the switch 5. Like in Connection with Fig. 4 will be explained in detail, includes the Switch 5 a continuation switch 35, which two stable operating conditions having. In the first state, one contact pair is opened, while in the second state Condition of this contact pair is closed. The third operating state of the Switch 5 is characterized in that both pairs of contacts 6a / 37, 6b / 38 are closed. In this case, the TV 1 is in operation and this "ON" state is signaled by the operating voltage display 7.

FIGS. 2 a to 2 c again show the various details Operating states of the switch 5. In Fig. 2a is the "OFF" state shown. In this operating state, the two pairs of contacts 6a / 37, 6b / 38 open, there is complete power separation to the connector 12. Fig. 2b shows the "STANDBY" state when the contact pair 6a / 37 is opened, while the contact pair 6b / 38 is closed. The third operating state is the "ON" state. In this operating state, both contact pairs 6a / 37, 6b / 38 closed. There is a connection between the plug 12 and the connection lines 2a, 2b, which feed the TV 1.

Fig. 3 shows a circuitry embodiment of a power supply of a device. In this case, those already described in connection with FIG. 1 introduced reference numerals used. Likewise, only for the Invention essential components shown. So the device has one Power supply device 2, a switch 5, a mains filter 15, a Demagnetization circuit 16, a rectifier circuit 17 with downstream capacitor 18, one of a microcomputer 4b and an infrared receiver 4a existing remote control receiver 4, a Energy storage 3, and a power indicator 7 and a Control transistor 19 on. Further, a boost converter 40 and a Capacitor 41 is provided.

The remaining circuit components shown in Fig. 3 are single components unspecified for reasons of clarity.

With regard to the basic function, FIG. 1 referenced. The infrared receiver 4a, the microcomputer 4b and the Energy storage 3 are all on the secondary side (cold side, net separated side) of the TV 1. In standby mode, too Called standby mode, the TV 1, the infrared receiver 4a and the microprocessor 4b supplied from the energy storage 3. One corresponding infrared command triggers over the control line 8 closing the Contact pair 6a / 37 off, the device starts and the energy storage 3 is charged again via the secondary side. So in the "STANDBY" operation as little energy is removed from the energy storage 3, an infrared receiver 4a is used, which is a so-called Owns low energy consumption operation. This is a Infrared receiver 4a, which in a mode with only one limited Detection is operable. This leads to a greatly reduced power consumption. The limited detection recognizes all without distinction incoming infrared signals. If a signal has arrived, then the switch Infrared receiver 4a to the nominal operation with higher power consumption, in which is a complete detection of the infrared commands. The one for the Standby operation provided microcomputer 4b can now receive the infrared signals decode. If this detection indicates that the received Infrared signal is a non-system signal. that's how it falls Infrared receiver 4a back into the energy saving mode. Becomes a native infrared signal detected, the device 1 is turned on. In the energy storage 3, it may be a battery, a battery or For example, to act as a so-called gold CAP. Is the device 1 in periodically switched to the "ON" state and becomes the Energy storage 3 reloaded and thus is an always possible Switching on the device 1 via the remote control and the Remote control receiver 4 possible. Only in the case that the device 1 a longer period of time in "STANDBY" mode remains, it may be possible be that the energy storage 3 is discharged. The switch 5 is designed to that by a slight press of the push button 20 of the switch 5, the device 1 can be put back into operation. This is indicated by reference numeral 14 and the corresponding arrow in Fig. 3. The device is pointing the practice in previously realized TVs no so-called "standby display" on. This is because even a light emitting diode in the "STANDBY" operation would consume too much energy and that Energy storage 3 would discharge quickly. Only for the display of the ON state an operating voltage display 7 is provided. About the Mechanical actuator 14 is mechanically a complete one Switch off, d. H. Opening both pairs of contacts 6a / 37, 6b / 38 possible, as well as a reconnection to the "BEREISTSCHAFTS" operation or from "STANDBY" operation in the "ON" state.

The optional in Fig. 3, for example, as a Swiched Capacitor trained up-converter 40 generated from the energy storage. 3 delivered voltage of for example 5 volts a higher voltage of for example 10-12 volts. This higher voltage is a safe Actuation of the coil 26 (see Fig. 4) of the advancer via the capacitor 41. The higher voltage at the output of the boost converter 40 has the Advantage that for generating a higher voltage, a second example can be saved in series connected further energy storage. Of the Boost converter 40 is used e.g. fed from the energy storage 3 and at Needed by the microcomputer 4b active while he is otherwise in the Hibernation is and only a few microamps consumed.

Fig. 4a shows a schematic diagram of a switch 5, as in the Connection with the 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 TV is visible and operable and arranged with Help to turn on or off the TV is enabled. Of the Push button 20 is connected via a first push rod 28 and a second Push rod 29 with the mechanical and electrical components of the Housing part 5 a of the switch 5 is coupled. The push rod 28 is connected to the Push button 20 not fixed, but movably stored in this. The Push rod 29, however, is fixed to the push button 20. The first push rod 28 acts via a linkage 33, 34 on the continuation switch 35, which is rotatably mounted in a pivot point 36. In the housing part 5a of Switch 5 is also a coil 26 and one with the second Push range 29 associated lever arm 22 is provided. 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 two mechanical actuation options. The first mechanical Actuation option is that the push button 20 only one short distance is pressed. In this case, the first push rod 28 in function and the progress switch 35 moves by 45 °, for example, whereby opening and closing of the contact pair 6a / 37 is effected. This is, by the shape of the embodiment of the sequencer 35 as Lever, the contact spring 6a through the extension switch 35 laterally from the fixed contact 37 pushed away, whereby the power supply via the Net, according to Fig. 2b, and Fig. 2c is interrupted or closed.

In addition to the taking place by means of the push button 20 first mechanical Operation of the continuation switch 35 is also the possibility of the Continuous switch 35 to operate electrically by means of the solenoid coil 26. Here, the opening and closing of the first contact pair 6a / 37 in the manner described above, but with the movement of the advancer 35 by acting on the linkage 33 magnetic display force the solenoid 26 is performed. Of course, the linkage 33 is magnetic or magnetizable.

This is done in response to a control command via the control line 8 (see Fig. 1 to Fig. 3) which causes the solenoid coil 26 via the linkage 33, 34, the progress switch 35 is actuated. By means of this first mechanical actuation or by means of the described electrical Actuation of the first pair of contacts 6a / 37, this contact is opened respectively or closed, indicating a change between the operating state "ON" and the "STANDBY" mode. The behind / under the first Contact pair 6a / 37 lying second contact pair 6b / 38 (see Fig. 4b) is in this both operating states always closed. By opening and Closing only one contact pair will also result in a small amount of energy needed to move the contact spring 6a.

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

The push rod 29 is formed such that at a short distance of the push button 20, the push rod 29 is not the lever arm 22 touches or pushes away, but the push rod 28 is already acting on the linkage 33, in the manner described above. The push rod 29 has on this route a mechanical idle. Only after overcoming this mechanical idling the push rod 29 acts on the lever arm 22 in the manner described above.
The spring 21, which is mechanically connected to the first push rod 28, serves the fact that, starting from a certain mechanical path, the mechanical idling of the second push rod 29, the first push rod 28 does not mechanically in the housing part 5a acts, but in the push button 20 moves into it and does not continue on the linkage 33 acts. At the same time sets the second push rod 29 a longer mechanical path in the switch 5 back. The spring 21 is selected in its spring force such that it exceeds the counter-force of the return spring 27 and the contact spring 6a.

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