The detection device of chamber temperature value and chamber pressure value, therefore, when upper cover 301 can be installed removably, these detection devices
Required electric power can be provided by wireless charging, and the control unit in cooker body 302 needs to receive these detection devices
The detection data sent from upper cover 301, and control is sent according to control unit of these detection datas into upper cover 302 and is referred to
It enables, to control the opening and closing of exhaust valve in upper cover 301.It therefore, can be in reality according to communication device shown in fig. 1 or fig. 2
While now providing electric power to the detection device of dismountable upper cover 301, the data completed between upper cover 301 and cooker body 302 are handed over
Mutually.
Embodiment two
Based on the identical technical concept of previous embodiment, referring to fig. 4, it illustrates provided in an embodiment of the present invention a kind of logical
Letter method, this method can be applied in household appliance, which may include power emission end and the nothing of wireless charging
The power receiving end of line charge electricity, which comprises
S401: power receiving end is sent the first data to be sent by receiving coil carrier wave according to the transmission cycle of setting
To power emission end；
S402: power emission end receives the first data to be sent, and carries out school inspection to the first data to be sent；
After S403: the first data school to be sent is examined successfully, power emission end passes through emission lines after the interval duration of setting
It encloses carrier wave and the second data to be sent is sent to power receiving end；
Wherein, the time span T of the transmission cycle is greater than the preset interval duration t1.
It should be noted that needing to realize the friendship of information and data between the both ends of wireless charging by coil carrier wave
Mutually, therefore, the communication between both ends belongs to semiduplex mode, for technical solution shown in Fig. 4, by setting regular time
Interval is to carry out the interaction of information and data, to avoid the communication disorder between power receiving end and power emission end；And
And since the time span of the transmission cycle of power receiving end is set greater than the interval duration that power emission end sends data,
So that at most only having one end on the time point of a certain determination, between power receiving end and power emission end is sending number
According to then also avoiding power receiving end and communication punching occur for when power emission end is communicated under wireless charging state
It is prominent, so that power receiving end and power emission end are able to carry out orderly communication.
The communication device in conjunction with described in previous embodiment, it is known that power receiving end in technical solution shown in Fig. 4 with
And power emission end respectively corresponds power receiver and power transmitter in communication device.
As a kind of achievable embodiment, it should be noted that when the described first data to be sent are for characterizing institute
When stating the working condition of equipment, second data to be sent include the corresponding control instruction of the working condition.Then, work as institute
When stating the first data to be sent for characterizing the working condition of the equipment, the power emission end is after the interval duration of setting
The second data to be sent are sent to the power receiving end by transmitting coil carrier wave, comprising the following three steps:
The working condition of the equipment is known according to the described first data to be sent in the power emission end；
The power emission end obtains corresponding control instruction according to the working condition of the equipment；
The control instruction is sent to after the interval duration of setting by transmitting coil carrier wave by the power emission end
The power receiving end.
Using electric pressure cooking saucepan as atypia example, the cooker body in electric pressure cooking saucepan is can be set in the power emission end of wireless charging
In, the power receiving end of wireless charging can be set in the upper cover of electric pressure cooking saucepan.For electric pressure cooking saucepan, upper cover is removable
That unloads is mounted in cooker body, therefore, the inner cavity temperature value of detection liner and the detection device of chamber pressure value is provided with when upper cover
When, electric power can be provided for detection device by way of wireless charging.It should also be noted that, detection device is obtained
Detection data, which needs to be transmitted to from upper cover, stews intracorporal control unit, stews intracorporal control unit and is determined whether according to detection data
Exhaust valve in upper cover is opened and closed, therefore, cooker body is also required to send to upper cover about row for detection data
The control instruction of air valve, so that the control unit in upper cover controls the opening and closing of exhaust valve according to control instruction.
Therefore, detection data obtained by the detection device in upper cover, for example, inner cavity temperature value and chamber pressure value these be used to describe electricity
The parameter of pressure cooker working condition is exactly the first data to be sent；And it stews intracorporal control unit and is obtained according to these detection datas
The control instruction of exhaust valve, the control instruction are exactly the second data to be sent, and the control unit in upper cover refers to receiving control
After order, it will be able to control the opening and closing of exhaust valve according to the instruction of control instruction.
Specifically, still by taking electric pressure cooking saucepan as an example, the upper cover of electric pressure cooking saucepan is provided with the inner cavity progress temperature for liner
The sensor of degree detection and pressure detecting, is additionally provided with the power receiver for carrying out wireless charging, identifies in this specific example
For host；The control unit analyzed for data is provided in the cooker body of electric pressure cooking saucepan, also as usual electric pressure cooking saucepan
Cooker body can be directly powered by alternating current, therefore, the power transmitter for carrying out wireless charging is provided with, in this specific example
In be identified as slave, waveform timing chart shown in Figure 5, host can send to slave according to fixed transmission cycle T and pass
The detection data of sensor；Slave will test data and verified after receiving detection data, and after verifying successfully, pre-
If interval duration t1 after, to host send be directed to detection data response data；It is to be appreciated that when detection data is inner cavity
Temperature value and pressure value use then response data then can be control instruction corresponding with the temperature value of inner cavity and pressure value
To control the opening and closing of exhaust valve in upper cover.Host is after receiving response data, and upper cover is according to response data come to row
Air valve is controlled.
As a kind of achievable embodiment, if it is considered that the duration that data are sent, then when the power receives
End a length of t2 when sending needed for first data to be sent, and the power transmitting terminal sends second data to be sent
When required when a length of t3, the time span T of the transmission cycle meets condition shown in following formula:
T>t1+t2+t3。
A kind of communication means is present embodiments provided, the friendship of information and data is carried out by setting fixed time interval
Mutually, to avoid the communication disorder between power receiving end and power emission end, power receiving end and power are also avoided
In wireless charging communication contention aware occurs for transmitting terminal, so that power receiving end and power emission end are able to carry out orderly lead to
