Embodiment 1
[0043] Embodiment 1 of the present invention provides a pot-off detection device for a cooker, such as figure 1 As shown, it includes a controller 1, a telescopic assembly 2, a support assembly 3, a detection assembly 4 and a cooktop body 5. The telescopic assembly 2 is sleeved on the support assembly 3 and moves up and down along the support assembly 3. The detection assembly 4 It is connected with the controller 1 and moves up and down with the telescopic assembly 2, and the controller 1 is electrically connected with the cooker body 5 to control the firepower of the cooker;
[0044] The detection assembly 4 includes a magnetic ruler 41 and a linear magnetic encoder 42 . The magnetic ruler 41 is fixedly connected to the telescopic assembly 2 through a baffle plate and moves up and down with the telescopic assembly 2 . The linear magnetic encoder 42 is electrically connected to the controller 1 . connected, the linear magnetic encoder 42 detects the displacement distance of t...
Embodiment 2
[0059] Embodiment 2 of the present invention provides a method for detecting the removal of a cooker from a cooker, such as figure 2 As shown, the application of the detection device for leaving the cooker for a cooker described in Embodiment 1 specifically includes the following steps:
[0060] S1, detect whether the cooktop body 5 has an ignition signal, if so, execute S2, otherwise continue to detect;
[0061] S2, the controller 1 drives the linear magnetic encoder 42 to work;
[0062] S3, the controller 1 reads the information of the linear magnetic encoder 42, and judges the state of the cookware according to the information;
[0063] S4, the controller 1 controls the firepower of the cooker according to the state of the cooker.
[0064] Specifically, in S3, the controller 1 reads the information of the linear magnetic encoder 42, and judges the state of the cookware according to the information, specifically:
[0065] S31, after the controller 1 drives the linear mag...

Abstract
The invention discloses an off-pot detection device and method for a stove. The off-pot detection device comprises a controller, a telescopic assembly, a supporting assembly, a detection assembly anda stove body, wherein the telescopic assembly sleeves the supporting assembly and moves up and down along the supporting assembly, the detection assembly is connected with the controller and moves upand down along with the telescopic assembly, and the controller is connected with the stove body and used for controlling the firepower of the stove; and the detection assembly comprises a magnetic ruler and a linear magnetic encoder, wherein the magnetic ruler is connected with the telescopic assembly, the linear magnetic encoder is connected with the controller, and the linear magnetic encoder detects the displacement distance of the magnetic ruler through magnetism. The telescopic assembly moves downwards or upwards according to the state (pot seating or pot leaving) of a pot to drive the magnetic ruler to move up and down, the magnetic encoder can collect the displacement of the magnetic ruler moving up and down and transmit the displacement to the controller, and the controller judgesthe state of the pot according to the displacement so as to adjust the firepower. Compared with traditional cookware state detection based on temperature, the scheme has higher sensitivity.
Description
technical field [0001] The invention belongs to the technical field of cookware state detection, and in particular relates to a cookware removal detection device and a detection method for a cooker. Background technique [0002] The traditional method for detecting the state of the pot on the cooker is: set a retractable temperature measuring probe on the cooker, and detect through the change of temperature; At this time, the flame will directly burn to the temperature measuring probe, so the temperature changes quickly, and when the pan is placed on the pot holder, the temperature measuring probe tests the temperature of the cookware, and the temperature changes slowly. Detect whether the pot is left or the pot is seated; or directly install springs, pressure springs, micro switches, etc. on the retractable temperature probe to detect the status of the pot or the pot. [0003] The state of the above-mentioned detection pot has the following defects: the temperature measuri...
