Fig. 1 is a schematic structural view of an induction cooker according to an embodiment of the present invention.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
the embodiment of the utility model discloses an electromagnetism stove control method, including following step:
and starting a power switch, selecting a cooking mode, transmitting a wave source signal with fixed frequency by the induction cooker, receiving a feedback signal, and judging whether a human body moves in a detection area according to the comparison between the frequency corresponding to the feedback signal and the fixed frequency so as to control the induction cooker to maintain a normal working state or stop working.
The cooking mode is a cooking mode, a stir-frying mode, a frying mode or a barbecue mode.
The fixed frequency is 2.5GHZ-5 GHZ.
When the cooking mode on the induction cooker is started, the method comprises the following steps:
the user selects a cooking mode by clicking a touch key or a key on the induction cooker or by voice, and simultaneously transmits a wave source signal with fixed frequency.
When the frequency corresponding to the feedback signal is greater than the fixed frequency, the normal working state of the induction cooker is maintained; when the frequency corresponding to the feedback signal is equal to the fixed frequency, detecting again after delaying for a first preset time period, and if the frequency corresponding to the feedback signal is equal to the fixed frequency, controlling the induction cooker to stop working; and if the frequency corresponding to the feedback signal is greater than the fixed frequency, maintaining the normal working state of the induction cooker.
And the induction cooker emits warning sound within the first preset time period.
The detection area is within the range of 0.5m-10m away from the center of the induction cooker.
And the induction cooker emits warning sound within the first preset time period to prompt a user to return in time. The first preset time period is 5s-30s, and different cooking modes can correspond to different times, for example, in a cooking mode or a stir-frying mode, the first preset time period can be 5 s; in the barbecue mode, the first preset time period may be 1 min; in the frying mode, the first preset time period may be 30 s. In other implementations, the first preset time period may also be comprehensively set according to different cooking modes and corresponding fire power levels.
The control method of the induction cooker is realized by relevant structural modules of the induction cooker. As shown in fig. 1, an induction cooker includes:
the cooking mode selection module 1 is used for selecting a cooking mode according to the requirement of a user;
a power switch unit 2 for making the induction cooker enter a standby state or stop working;
the human body detection module 3 comprises a wave source 33 for transmitting pulse waves with fixed frequency to the periphery, a transmitting unit 31 for transmitting the wave source 33, a receiving unit 32 for receiving feedback signals and a frequency analysis module 34 for comparing the frequency corresponding to the feedback signals with the fixed frequency;
the control module 4 is used for controlling the induction cooker to maintain a normal working state or stop working;
the cooking mode selection module 1, the power switch unit 2 and the human body detection module 3 are all connected with the control module 4.
The human body detection module 3 is a doppler radar.
When the frequency corresponding to the feedback signal is greater than the fixed frequency, the control module 4 maintains the normal working state of the induction cooker; when the frequency corresponding to the feedback signal is equal to the fixed frequency, detecting again after delaying a first preset time period, and if the frequency corresponding to the feedback signal is equal to the fixed frequency, disconnecting the power switch unit 2 by the control module 4 to stop the work of the induction cooker; if the frequency corresponding to the feedback signal is greater than the fixed frequency, the control module 4 maintains the normal working state of the induction cooker.
The control module 4 includes a first preset time unit 41, and the first preset time period is set in the first preset time unit 41.
The induction cooker further comprises an alarm unit 5, wherein the alarm unit 5 is connected with the control module 4 to control the alarm unit 5 to give out alarm sound within a first preset time period set by the first preset unit 41.
Turning on a power switch, enabling the induction cooker to enter a standby mode, selecting a cooking mode, if the cooking mode, the quick-frying mode, the frying mode or the barbecue mode is selected, for example, the control module sends out and executes a corresponding cooking mode, simultaneously starts a human body detection module to emit a wave source with fixed frequency to the periphery, receives a feedback signal, detects the frequency corresponding to the feedback signal and the magnitude of inherent frequency to judge whether a person moves in a detection range, and further determines whether the person is on the spot, if the frequency corresponding to the feedback signal is greater than the inherent frequency, the fact that the person is on the spot is indicated, and the induction cooker is in a normal working state; if the frequency corresponding to the feedback signal is equal to the natural frequency, retesting, if the frequency corresponding to the feedback signal is equal to the natural frequency, indicating that a person is not on the spot for a long time, controlling a power switch to be turned off, and stopping working; if the frequency corresponding to the feedback signal is greater than the natural frequency, the induction cooker is in a normal working state when a person is on the spot.
The utility model discloses an electromagnetic oven, because stir-fry mode or fry mode etc. need someone always to operate and monitor, otherwise can burn to stick with paste or burn, danger such as conflagration appears even, control above-mentioned culinary art mode through above-mentioned method, and more intelligent, the security is high, effectively avoids the user to leave the electromagnetic oven of working for a long time and takes place to stick with paste pot or fire accident; meanwhile, an alarm unit is arranged to remind a user to return to the induction cooker in time for corresponding operation, so that pan burnt or fire accidents are avoided.
