Optionally, the fool-proof structure 101 may also be a mechanical structure, the first fool-proof module 1 and the second fool-proof module 2 may be mechanical components that can cooperate with each other to be engaged, when the air conditioner is powered on, the first fool-proof module 1 and the second fool-proof module 2 are automatically engaged to prevent the user from opening the panel 3, and when the air conditioner is powered off, the first fool-proof module 1 and the second fool-proof module 2 are automatically separated to facilitate the user to open the panel 3.
Referring to fig. 5, in one embodiment of the present disclosure, the detecting module 102 is used to detect whether the panel 3 is opened when the air conditioner is powered on, and the detecting module 102 may be a photosensitive sensor disposed between the panel 3 and the middle frame 4. When the panel 3 is closed, the photosensitive sensor element cannot detect an obvious light source, and no signal is fed back to the control module 103; when the panel 3 is opened, the photosensitive sensing element receives an optical signal in the environment, converts the optical signal into an electric signal and feeds back the electric signal to the control module 103, and informs the control module 103 that the panel 3 is opened by a user, so that the control module 103 timely controls the main circuit of the air conditioner to be powered off.
Alternatively, when the detection module 102 is a photosensitive sensor, the photosensitive sensor may be disposed at the bottom edge 5 of the middle frame. When the panel 3 is opened, the light of the bottom edge 5 of the middle frame begins to change firstly, the change is most obvious, and the photosensitive sensing element is arranged at the bottom edge 5 of the middle frame, so that the relative sensitivity and accuracy of the photosensitive sensing element are optimal.
Optionally, the detection module 102 may also be a gravity sensing element. The gravity sensing element is arranged on the panel 3, when the panel 3 is closed, the gravity sensing element can not detect the change of the gravity center, and no signal is fed back to the control module 103; when the panel 3 is opened, the gravity sensing element detects that the gravity center is obviously changed, and the gravity sensing signal is converted into an electric signal to feed back the control module 103. At present, the sensitivity of the gravity sensing device in the market is high, so the gravity sensing device can be intelligently arranged at any position on the panel 3.
Optionally, the detection module 102 may also be an infrared sensing element. The infrared sensor element may be disposed at the bottom edge 5 of the middle frame at which the relative sensitivity and accuracy of the infrared sensor element are optimized, and whether the panel 3 is opened or not is judged by sensing the change of the infrared radiation in the environment.
In one embodiment of the present disclosure, the apparatus further comprises: and the alarm module is used for prompting a user to power off the air conditioner by voice after the panel 3 is detected to be opened. When the air conditioner is in a power-on state, when a user overcomes the action of the fool-proof structure 101 to forcibly open the panel 3, the alarm module can remind the user that the current air conditioner is not powered off in time, and inform the user of turning off the power supply of the air conditioner or pulling off the plug in time through voice, so that the user can unpick, wash, maintain, check and the like the air conditioner under the safe condition.
Optionally, the alarm module can alarm through voice broadcasting, sound alarm modes such as a buzzer and visual alarm modes such as light display.
In one embodiment of the present disclosure, the apparatus further comprises: and the automatic power-off module is used for automatically powering off the air conditioner when the alarm time of the alarm module reaches the preset time. If the user has opened the panel 3 of air conditioner by force when the air conditioner circular telegram, and the user still does not cut off the power supply of air conditioner under alarm module's suggestion, in order to avoid the accident to take place, when alarm module reports to the police when long reaching and presets for a long time, the circuit with the air conditioner is completely disconnected automatically, protects user's safety.
Fig. 6 schematically shows a flowchart of a power outage control method proposed by the present disclosure, including steps S1-S3.
S1, when the air conditioner is powered on, the panel 3 of the air conditioner is prevented from being opened by the fool-proof structure 101.
S2, it is detected whether the panel 3 is opened.
S3, if the panel 3 is opened, the main circuit of the air conditioner is controlled to be powered off.
In the embodiment of the present disclosure, when the air conditioner is powered on, the fool-proof structure 101 fixes the air conditioner panel 3 and the middle frame 4 together, so as to prevent the panel 3 from being opened by a user during the working process of the air conditioner, and the air conditioner is disassembled and cleaned, thereby causing a safety accident. Meanwhile, the detection module 102 detects whether the panel 3 is still opened by the user under the protection of the fool-proof structure 101, in this case, the detection module 102 immediately notifies the control module 103, and the control module 103 powers off the main circuit of the air conditioner, thereby preventing a safety accident. According to the method, on one hand, the panel 3 is prevented from being opened by a user through the fool-proof structure 101, on the other hand, the processing scheme that the panel 3 is opened in the power-on process of the air conditioner is further perfected through the detection module 102 and the control module 103, and the double guarantee that the user is prevented from detaching the air conditioner and the safety accident caused by detaching the air conditioner in the power-on process of the air conditioner is realized.
The method further comprises step S4.
S4, when the air conditioner is powered on and the panel 3 is opened, the user is prompted by voice to power off the air conditioner; and when the air conditioner is powered off, stopping voice prompt.
In one embodiment of the present disclosure, after the user opens the panel 3 by overcoming the protection effect of the fool-proof structure 101, the controller disconnects the main circuit of the air conditioner, so that the main power utilization circuit of the air conditioner is disconnected, and prompts the user by voice to pull out the socket of the air conditioner, so that the air conditioner is completely powered off, and the power failure of the air conditioner can be really guaranteed, and the user can not have potential safety hazards in operations such as detaching, cleaning and checking the air conditioner.
The method further comprises step S5.
And S5, when the alarm time of the alarm module reaches the preset time, the air conditioner is automatically powered off.
In one embodiment of the present disclosure, after the user opens the panel 3 by overcoming the protection effect of the fool-proof structure 101, the controller disconnects the main circuit of the air conditioner to disconnect the main power circuit of the air conditioner, and prompts the user by voice to pull out the socket of the air conditioner or trip the air switch of the air conditioner to completely power off the air conditioner, so as to really ensure that the air conditioner is powered off, and the user can detach, clean, inspect and the like the air conditioner without potential safety hazard.
The air conditioner comprises the power-off control device and the power-off control method, the air conditioner can be prevented from being disassembled by a user when the air conditioner is powered on, and the user is prompted to power off the air conditioner after the air conditioner panel 3 is opened, so that potential safety hazards are avoided.
