Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "inner", "outer", and the like, indicate orientations or positional relationships, are used for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referenced components or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The invention relates to a detection device and a detection method for a shelf in a refrigerator, which comprises a main control board, an actuating mechanism, a feedback assembly and at least one detector, wherein the main control board is connected with the actuating mechanism; the detectors are arranged in the refrigerator, the number of the detectors is not less than that of the shelves, so that each shelf in the refrigerator corresponds to a corresponding detector, and a contact of each detector is in contact and press fit with one end of each shelf; when the detector is not pressed, namely the power is released and cut off, the main control board cannot receive a feedback signal, and therefore the shelf position is judged to be moved. The number of the executing mechanisms is at least one, and the control system gives a command to the executing mechanisms and restores the shelf to the initial position through the work of the executing mechanisms.
The detector, the refrigerator body, the refrigerator door body, the feedback assembly, the actuating mechanism and the main control board are all electrically connected.
Example one
Preferably, the feedback component is a loudspeaker or a WiFi module or a warning light, and the warning light comprises a red dazzling flashing light and a green soft light.
Referring to fig. 1, a method for detecting a shelf detection device in a refrigerator includes the following steps:
s1, electrifying the refrigerator and starting the control system;
s2, detecting whether the refrigerator door is closed, if so, feeding back the normal state by the feedback assembly and executing S3; if not, the feedback assembly feeds back abnormity within a certain time T0 to remind the user to close the door and returns to S2 to detect whether the refrigerator door is closed again;
s3, the control system detects whether the main control panel can receive the power-on signal fed back by the detector, if so, the contact of the detector is in a pressing state, namely the shelf is at the initial position and does not move, and the feedback component feeds back normally and executes S4; if not, the detector is in a release state at the moment, the glass shelf is already deviated, and the feedback component feeds back an abnormity to remind a user to close the door and execute S4;
and S4, ending the system.
Preferably, the feedback component feeds back the normality by controlling the light to flicker green, and the feedback component feeds back the abnormality by controlling the light to flicker red.
Example two
The difference from the first embodiment is that: the feedback component is a speaker, preferably, the feedback component plays feedback abnormality through the speaker voice, if a corresponding signal can be received in S3, it indicates that the detector is in a press-fit state at this time, that is, the shelf is at the initial position and does not move, and then S4 is executed. Otherwise, the detector is in a release state, which indicates that the shelf is deviated, and the control system makes a voice prompt through the loudspeaker.
EXAMPLE III
The difference from the first embodiment and the second embodiment is that: the detector is a limit switch, the feedback component is a WiFi module, preferably, the feedback component sends information feedback abnormity to a mobile phone of a user through the WiFi module and a network, and if a corresponding signal can be received in S3, the detector is in a pressing state at the moment, namely, the shelf is at an initial position and does not move, and then S4 is executed. Otherwise, the detector is in a loose state, which indicates that the shelf is deviated, and the control system sends information feedback abnormity to the mobile phone of the user through the WiFi module and the network.
In addition, after the refrigerator is powered on in S1, whether the WiFi module of the refrigerator is connected with a network or not is detected through the system, namely whether the WiFi module of the refrigerator is connected with a household router or not, if yes, S2 is executed, and if not, the door body of the refrigerator is closed through an execution mechanism.
Preferably, in S3, the main control board cannot receive the power-on signal fed back by the detector, and the feedback component feeds back the abnormality and then returns the shelf to the initial position through the actuator.
