In this respect, be sent to its door being used for essential energy of this purpose and data from electric device, this process can be subjected to cable influence.The shortcoming of doing like this is that the tie point of door must be fixed in advance, and wiring operations must be finished among production run, and the switch door danger that can bring cable bad repeatedly.
Summary of the invention
As basic point of departure, the objective of the invention is to propose the method for a kind of transmission of power and data with prior art above-mentioned, and a kind of electric device of realizing this method, these shortcomings of wherein having pointed out no longer occur.
The method of the technical characterictic of this target by having claim 1, and the electric device with technical characterictic of claim 5 is realized.Structure of the present invention and improvement are illustrated in the dependent claims.
The wireless transmission of energy and the data door from the electric device to the electric device has been eliminated the needs of line between electric device and door.Like this, at any time can at random select the deflection angle of door, the line operation in the production run also can be saved, and does not have to cause owing to the repeat switch door danger of cable bad.
The transmission of energy and/or data realizes by alternating electromagnetic field that preferably alternating electromagnetic field is produced by the primary coil on first ferromagnetic core, and is received by the secondary coil on second ferromagnetic core.Improvement of the present invention can provide the light transmission of data, preferably passes through infrared ray.
Be used for realizing the electric device of this method, the cover electronic gate system in a cover electronic control system in having electric device and the door of electric device, also has a transmitting device that comprises primary part and sub section, wherein effectively (operatively) primary part of being connected to electronic control system is arranged in the electric device, and the sub section that effectively is connected to the electronic gate system is arranged in the door of electric device.
Preferably primary part and sub section all comprise a U-shaped or a semi-round ring shape electromagnetic core that is wound with coil respectively.
For the light data transmission, second transmitting device can be provided in addition, it has an infrared receiving set that is arranged in the door that infrared transmitter in the electric device and is arranged on electric device.In order to allow the bi-directional light data transmission, another transmitting device also is provided, its infrared transmitter is arranged on the door the inside of electric device, and infrared receiving set is arranged in the electric device.
The primary part of transmitting device and sub section preferably are provided with like this: when door is shut, they toward each other and distance very near.
In the modified of the present invention, being arranged in the door of electric device is the intermediate energy memory storage, preferably capacitor or accumulator.At least when door is closed, the intermediate energy memory storage can charge by first transmitting device, and, when the energy supply by first transmitting device the time by short interruption, for example door is in the position of opening, the consumer supply energy source of intermediate energy memory storage in the door that is installed in electric device.
Description of drawings
Describe one embodiment of the present of invention below with reference to accompanying drawings in detail.In the accompanying drawing,
Fig. 1 is a diagram of describing energy and data transmission principle,
Fig. 2 is the diagram of transmitting device.
Embodiment
The electronic control system 1 of refrigerator provides needed electric energy from public electric wire net.Electronic gate system 2 is installed in the refrigerator doors, is used for controlling display device and action button.Electric refrigerator system 1 is 2 power supplies of electronic gate system by transmitting device 3.The data of display device (temperature that reaches in the refrigerator for example, the progress of the operation of perhaps thawing) are sent to electronic gate system 2 by transmitting device 3.About to the data of the operation that is installed in the action button on the refrigerator doors (such as changing cryogenic temperature or the switching operation of thawing) from electronic gate system 2 by transmitting device 3 by the reverse electric refrigerator system 1 that is sent to, data are further processed there.
Transmitting device 3 comprises primary part 4 and sub section 5.Primary part 4 and sub section 5 comprise U-shaped electromagnetic core 6 and 7 respectively, and the xsect of electromagnetic core is rectangle or circle, and each electromagnetic core has two coils, are respectively 8,9 and 10,11.Also can use two semicircular ring iron cores to replace U-iron core 6 and 7.
Primary part 4 and sub section 5 are separately positioned on the back of the lining 13 of the lining (lining) 12 of refrigerator and door, at least when door is shut, they toward each other and distance very near.
5 power transfer is subjected to the alternating current influence by coil 8 from primary part 4 to sub section, alternating current produces alternating electromagnetic field at iron core 6, because primary part 4 and sub section 5 are locational approaching, alternating electromagnetic field is delivered to iron core 7, cause an alternating voltage in coil 10, it can be removed at the end points of coil 10.Data are transmitted in a similar fashion by coil 9 and 11.Yet data also can be transmitted by same coil with energy.Yet, note guaranteeing to use the frequency different with energy, perhaps use different percent makes to transmit data.Like this, at the sub section of transmitting device, by suitable wave filter, data can be distinguished, and separate from energy.Compare with power transfer, data transmission is two-way, so data can either be sent to the coil 11 of sub section 5 from the coil 9 of primary part 4, also can transfer back to the coil 9 of primary part 4 from the coil 11 of sub section 5.
Alternatively, can realize the optical delivery of data by infrared transmitter unit and infrared receiving set unit.In this respect, when light data transmission when being two-way, on each direction, all need a pair of transmission and receiving element.
Electronic gate system 2 effectively is connected to as the capacitor of intermediate energy memory storage or rechargeable battery, when door is closed, the intermediate energy memory storage charges by transmitting device 3, and when door when opening, and provides electric energy to electronic gate device 2 and display element and action button.If the structure of transmitting device makes energy also can transmit, then no longer need such intermediate storage mean as can be known when opening the door.
