Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

What the utility model discloses is an intelligent opening and closing kitchen cabinet, as shown in Fig. 1 to Fig. 5, which is a preferred embodiment of the utility model. The cabinet includes a PLC controller 1 electrically connected to each other, a power supply unit 2, an electric control device 3 for controlling the opening or closing of the cabinet door, and a vibration switch for receiving a vibration signal to control the electric control device 3 to open the cabinet door by the PLC controller 1. 4 and receiving the photoelectric signal, the PLC controller 1 controls the electric control device 3 to close the photoelectric switch 5 of the cabinet door. Further, a relay 6 is electrically connected between the PLC controller 1 and the electric control device 3 .

The working principle of the utility model is: when the cabinet door is to be opened, knock the cabinet, the vibration switch 4 detects the vibration of the cabinet body or the cabinet door, and transmits the vibration signal to the PlC controller 1, and the PlC controller 1 will pass the control The relay 6 indirectly controls the electric control device 3 to perform the opening action, so that the cabinet door is opened to complete the opening action.

When the cabinet door is to be closed, the photoelectric switch 5 is blocked, and the photoelectric switch 5 detects a shading signal or an infrared signal, and transmits the signal to the PlC controller 1, and the PlC controller 1 will indirectly control the electric control device 3 through the control relay 6 to execute closing Action to close the cabinet door and complete the closing action.

Considering that the cabinet door is opened incorrectly due to the interference of external vibrations, the utility model can set the PLC controller 1 to receive two electrical signals within 1 second before it can output a control signal to make the electric control device 3 open.

Similarly, in order to prevent the photoelectric switch 5 from being interfered by other external objects and cause the cabinet door to be closed incorrectly, the photoelectric switch 5 can be set to receive two photoelectric signals within 1 second before the PLC controller 1 that receives the signal responds to control the electric control. Device 3 performs closing action.
