Reception pipe 45.Transmitting line device 41 is connect with transmitting tube 44.Circuit device 42 is received to connect with reception pipe 45.Transmitting line dress
It sets 41 and is configured to send the first household electrical appliance 20 to the linkage signal of one second household electrical appliance 30.Circuit device 42 is received for connecing
Receive external signal.Receiving circuit device 42 includes signal recognition circuit 43, and whether external signal is from second for identification
The feedback signal to linkage signal of electrical appliance 30.
In the embodiment shown in fig. 4, signal recognition circuit 43 external signal can be compared with linkage signal, when outer
When portion's signal and linkage Signal Matching, determine that external signal is feedback signal, otherwise determines that external signal is not feedback signal.Letter
Number identification circuit 43 can connect transmitting line device 41 to receive linkage signal.In relatively external signal and linkage signal,
Signal recognition circuit 43 can carry out waveform comparison.For example, external signal and linkage signal can have identical signal
Head, this signal heads can represent the identification code of the first household electrical appliance 20.When signal recognition circuit 43 believes external signal and linkage
Number after comparison, it was found that, when external signal and linkage signal signal heads having the same, it is believed that external signal is from second
The feedback signal to linkage signal of electrical appliance 30.
Signal recognition circuit 43 connects controller 24 to export recognition result, when external signal is not feedback signal, controls
Device 24 processed determines that the second household electrical appliance 30 do not receive linkage signal, to indicate that transmitting line device 41 sends linkage letter again
Number；When external signal is feedback signal, controller 24 determines that the second household electrical appliance 30 have been received by linkage signal, and instruction sends electricity
Road device 41 sends another linkage signal.
In the embodiments of the present invention, transmitting line device 41, which is sent between the adjacent signal that links twice, a waiting
Time, so that the second household electrical appliance 30 have time enough response.
As previously mentioned, the signal transmitted between remote controler 10, the first household electrical appliance 20 and the second household electrical appliance 30, such as it is distant
Controlling signal, linkage signal and feedback signal is infrared signal respectively.
In the present embodiment, transmitting line device 41 sends linkage signal by the ballistic device of such as transmitting tube 44, connects
It receives circuit device 42 and external signal is then received by the receiving device of such as reception pipe 45.
One-wire interface can be used between transmitting line device 41 and controller 24.Receive circuit device 42 and controller 24 it
Between one-wire interface can also be used.
Fig. 5 is the structure chart according to the signal processing apparatus of an embodiment of the present invention.Refering to what is shown in Fig. 5, this implementation
Example and the main distinction of previous embodiment are that the default input of signal recognition circuit 43 is preset signals rather than from transmission electricity
The linkage signal of road device 41.External signal is compared signal recognition circuit 43 with preset signals, when external signal and in advance
If when Signal Matching, determining that external signal is feedback signal, otherwise determine that external signal is not feedback signal.Preset signals can be with
From controller 24, it can be from other devices.
It is usually to be mentioned during executing an a series of actions for the controller 24 of the first household electrical appliance 20
For linkage signal to signal processing apparatus 22.Fig. 6 is the another household electrical appliance interactive process according to an embodiment of the present invention
Example.Refering to what is shown in Fig. 6, remote controler 10 sends remote signal to the first household electrical appliance 20；When the first household electrical appliance 20 are thought to need
When linking with the second household electrical appliance 30, the transmitting line device 41 of the first household electrical appliance 20 sends linkage signal to the second household
Electric appliance 30；Remote controler 10 issues remote signal because user operates again again；At this time at the signal of the first household electrical appliance 20
Signal recognition circuit 43 in reason device 22 will do it signal identification, when the external received remote signal of discovery and link signal not
When matching, linkage signal is sent again；On the other hand, the second household electrical appliance 30 return feedback signal gives the first household electrical appliance 20,
Confirm that it has received linkage signal；Signal recognition circuit 43 in the signal processing apparatus 22 of the first household electrical appliance 20 can be at this time
Row signal identification sends another linkage signal to second when the external received feedback signal of discovery and linkage Signal Matching
Electrical appliance 30；... so circulation, until passing through time t1Afterwards, the linkage of the first household electrical appliance 20 and the second household electrical appliance 30 is complete
At.Then enter second stage, remote controler 10 sends remote signal to the first household electrical appliance 20, and the first household electrical appliance 20 respond distant
The order that the remote signal of control device 10 includes, is acted；Remote controler 10 sends another remote signal to the first household electrical appliance 20,
The order that another remote signal of first household electrical appliance 20 response remote controler 10 includes, is acted.
Therefore by the signal identification and collision detection of signal processing apparatus, can allow the first household electrical appliance 20 it is anticipated that
Control flow running, avoid the occurrence of the situation that can not be handled.
The application scenarios of the utility model are enumerated below, and the first household electrical appliance are air-conditionings, and the second household electrical appliance are that air is net
Change device.When the starting of remote control control air-conditioning system, air-conditioning prepares starting, but detecting room air not is very well, so empty
Adjusting system sends linkage signal to air purifier, allows air purifier first to do purification air, then air-conditioning system is according still further to setting
Mould-fixed opens operating.If air-conditioning system receives the remote signal of remote controler at this time again, air-conditioning system can detect remote control
The remote signal of device and the linkage signal for being emitted to air purifier mismatch, and air-conditioning system does not execute the dynamic of remote signal instruction
Make, but sends linkage signal again to air purifier.When air-conditioning system receives the feedback signal of air purifier return,
It can detect itself and the linkage Signal Matching for being emitted to air purifier, air-conditioning system continues to execute process, if necessary
Another linkage signal is sent to air purifier.By time t1Afterwards, it is complete to feed back to air-conditioning system purification air for air purifier
At air-conditioning system opens operating according still further to setting mode.
Therefore, the household electrical appliance of the utility model and its signal processing apparatus can complete conflict inspection by signal identification
It surveys, so that it is guaranteed that household electrical appliance are according to scheduled process operation.
Although the utility model is described with reference to current specific embodiment, ordinary skill in the art
Personnel it should be appreciated that more than embodiment be intended merely to illustrate the utility model, be detached from the spirit of the present invention no
In the case of can also make various equivalent change or replacement, therefore, as long as to upper in the spirit of the utility model
State the variation of embodiment, modification will all be fallen in the range of following claims.
