Make the service life.In addition, the electromagnetic stove works without artificial selection heating unit 11, while without relying on the work of heating unit 11
Under the premise of carry out inspection pot, improve reliability, and more intelligent.
Fig. 7 is the flow chart of the cookware detection method for the electromagnetic stove that second aspect of the present invention embodiment proposes.Such as Fig. 7 institute
Show, detection method includes the following steps for the cookware of the electromagnetic stove:
S701, cookware detection unit detect cookware, and when the generation when having detected that cookware is placed on panel
Detect signal.
S702, control module is according to the position for detecting signal acquisition cookware.
S703, control module control heating unit corresponding with the position of cookware and work.
Wherein, in an embodiment of the present invention, heating unit and cookware detection unit all can be one, also all can be
It is multiple.Preferably, heating unit and cookware detection unit are multiple.
In one embodiment of the invention, heating unit is multiple, and cookware detection unit is multiple, and multiple heating
Unit and multiple cookware detection units are arranged in array.
That is, in an embodiment of the present invention, cookware detection unit is arranged on heating unit or adjacent heating is single
Between member.It is arranged one for example, being arranged between one or more pot detection units or adjacent several heating units on each heating unit
A cookware detection unit.Cookware detection unit is detecting that cookware is placed on panel or detects the pot placed on panel
Tool is when removing, and will generate detection signal and will test signal and feeds back to control module, and control module obtains cookware detection unit
Behind location information, that is, cookware position, process instruction whether heating to corresponding heating unit will be issued, control heating is single
Member is heated or stops heating.
Further, in one embodiment of the invention, as shown in Fig. 2, when cookware detection unit 12 be resistance-type or
When the mechanical cookware detection unit of person (i.e. induction detection unit), every interconnection of row cookware detection unit 12 and array in array
Middle each column cookware detection unit 12 is equally connected with each other, and every row cookware detection unit 12 in array and control module 40 are homogeneous

In the present embodiment, it is detected using matrix form Scanning Detction mode, as shown in figure 8, the pot of above-mentioned electromagnetic stove
Detection method includes the following steps for tool:
S801, the input terminal of control module each column cookware detection unit into array export scanning signal, such as input one
A high level signal.
S802, control module acquire the output signal of the output end of every row cookware detection unit in array, i.e. detection signal.
S803, control module obtain position and/or the size of cookware according to output signal.
S804, control module control heating unit corresponding with cookware position and/or size and work.
Specifically, in an example of the invention, control module can have single-chip microcontroller, which includes PA0-
Eight output ports of PA7, eight input ports of PB0-PB7 and eight cookware register PAN (COUNT_VER), wherein PA0-
Eight output ports of PA7 are connected with eight column cookware detection unit of X0-X7, eight row cookware of eight input ports of PB0-PB7 and Y0-Y7
Detection unit is connected.As shown in figure 5, the process of specific matrix form scanning mode the following steps are included:
S501, single-chip microcontroller initialize eight output ports of PA0-PA7, and it is high that eight output ports of PA0-PA7 are set to output
Level, i.e. PA are set as 0XFF.
S502, single-chip microcontroller initialize eight input ports of PB0-PB7, eight input ports of PB0-PB7 are set as inputting,
And by eight cookware register PAN (COUNT_VER) clear 0.
PA=0XFE, cookware register COUNT_VER=0 is arranged in S503.
Whether S504, the resistance value for successively scanning each port PB0-PB7 change.If so, executing step S505；
If not, executing step S506.
S505, wherein certain road or multi-channel port resistance value change, and cookware register PAN (COUNT_VER) is corresponding
Relevant position 1.
S506, wherein certain road or multi-channel port resistance value do not change, and cookware register PAN (COUNT_VER) is corresponding
Relevant bits are also 0.
S507, PA move to left 1 (i.e. highest order is spilled over to lowest order) without carry, and cookware register COUNT_VER adds 1.
S508, judges whether COUNT_VER is equal to 8.If so, executing step S509；If not, return step S504,
It continues to scan on.
S509 obtains the position of cookware according to the judgement of the value of the register of eight cookware register PAN (COUNT_VER)
And/or size.
That is, in the present embodiment, resistance-type or mechanical induction detection unit are assemblied in the upper of heating unit
Side, control module are acquired the variable quantity of resistance or the knots modification signal of machine performance, are scanned to realize with matrix form
Mode carries out the detection of cookware state, and control module starts or close corresponding heating unit according to cookware state.
The position of cookware on panel and/or size are detected by using matrix form Scanning Detction mode, improved
Detection accuracy.
In another embodiment of the present invention, when cookware detection unit is condenser type or inductance type cookware detection unit
When, each cookware detection unit is connected with control module.It is detected by the way of detecting one by one at this time, above-mentioned electromagnetism
The cookware detection method of stove further includes two steps: control module acquires the detection signal of each cookware detection unit, and controls
Position and/or size of the molding root tuber according to detection signal acquisition cookware.
That is, using condenser type or inductance type cookware detection unit, using the mode detected one by one.Control module is logical
Cross the identification and processing for acquiring the variable quantity progress signal inductively or capacitively of each cookware detection unit, the detection of each cookware
Unit corresponds to I/O mouthfuls of a detection of control module, and control module determines that cookware detects by way of detecting control mouth one by one
The state of unit, whether according to the heating of the corresponding heating unit of this state controlling module controls.
In the present embodiment, control module is according to detection signal using the position pair for the principle control and cookware for closing on local
The heating unit answered works.In other words, by the way of detecting one by one, the state of each cookware detection unit is examined
It surveys, control module is according to the state of detection unit, using the principle for closing on local, whether controlling the heating of heating unit.Wherein,
Close on local principle are as follows: as shown in fig. 6, effectively such as the cookware detection unit 12 of X4 and Y4 intersection, control module 40 is simultaneously
Go the state (such as X3 and Y4, X3 and Y3, X3 and Y5 etc.) of the adjacent one cookware detection unit 12 in detection periphery.When closing on shape
There is the state of such as 3-4 cookware detection unit 12 of predetermined number effective simultaneously in state, control module 40 is by the heating in this region
The starting heating of unit 11, if only only having such as 1 cookware detection unit 12 of very few that will not effectively start heating in the region.
The position of cookware on panel and/or size are detected by using the mode detected one by one, subject to detection more
Really, it avoids and erroneous judgement occurs, energy conservation and environmental protection, high reliablity.
In yet another embodiment of the present invention, when the corresponding heating unit of multiple cookware detection units, mould is controlled
Block judges that control is examined with multiple cookwares when predetermined number such as 3-4 in multiple cookware detection units cookware detection units are effective
