For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Please refer to Figure 1 , Figure 1 The figure is a schematic circuit diagram of a refrigerator built-in light on / off control system according to an embodiment of the present invention.

[0032] The present invention provides a method for controlling the on / off of a built-in lamp of a refrigerator, which is used to realize automatic control of the on / off of a built-in lamp 1 of the refrigerator.

[0033] The structure of the refrigerator is as follows: it includes a refrigerator body, which generally has two inner chambers, one is a refrigerator chamber and the other is a freezer chamber. For refrigerators with more comprehensive functions, there will be a third inner chamber, namely a fresh-keeping chamber. Generally, only the refrigerator chamber is provided with a built-in light 1. Corresponding to each inner chamber, a refrigerator door is provided. On the refrigerator body, each inner chamber is provided with a refrigerator body liner, and on the refrigerator door is provided with a refrigerator door liner.

[0034] In the prior art, a mechanical switch is provided on the inner liner of the refrigerator body. When the refrigerator door is opened, the mechanical switch is turned on, and the built-in light 1 is powered on and bright. When the refrigerator door is closed, the refrigerator door inner liner provided on the refrigerator door contacts the mechanical switch, the mechanical switch is turned off, and the built-in light 1 is powered off and turned off. The mechanical switch used in the prior art is prone to problems such as stuck and inflexible pop-up.

[0035] In order to solve the above problems, the present invention proposes a method for controlling the on / off of a built-in light of a refrigerator. The method has the following specific steps, including:

[0036] Step 1: Use infrared monitoring to monitor the opening or closing state of the refrigerator door;

[0037] Step 2: When the refrigerator door is detected to be opened, the built-in light 1 is controlled to be turned on; when the refrigerator door is detected to be closed, the built-in light 1 is controlled to be turned off.

[0038] Specifically, step one includes: step one a, after the refrigerator door is closed, the area occupied by the inner liner set on the refrigerator door is the selected area, and part of the selected area is selected as the monitoring area; step one b, an infrared monitoring device is set according to the monitoring area, and the infrared monitoring device performs real-time monitoring of whether there is a refrigerator door inner liner in the monitoring area.

[0039] Specifically, step 2 specifically includes: step 2a, when the infrared monitoring device detects that there is no refrigerator door liner in the monitoring area, control the built-in light 1 to turn on; step 2b, when the infrared monitoring device detects that there is a refrigerator door liner in the monitoring area, control the built-in light 1 to turn off.

[0040] Specifically, in step 2b, when the infrared monitoring device detects that there is a refrigerator door liner in the monitoring area, the built-in light 1 is controlled to be turned off after a delay of 2s-4s from the monitoring moment.

[0041] In the above control method, the present invention uses an infrared monitoring device to monitor in real time whether the refrigerator door is open. The infrared monitoring device has two units, one of which is an infrared transmitter and the other is an infrared receiver. The infrared transmitter and the infrared receiver can be installed in a hidden manner on the inner liner of the refrigerator body. By transmitting and receiving infrared rays, the position change of the refrigerator door liner is monitored in real time. The refrigerator door liner is set on the refrigerator door. After the refrigerator door is closed, the setting position of the refrigerator door liner relative to the refrigerator body remains unchanged. After the refrigerator door is opened, the position of the refrigerator door liner will change relative to the refrigerator body. The present invention monitors whether the refrigerator is open according to the change in the position of the refrigerator door liner. If the refrigerator door is opened, the position of the refrigerator door liner changes, and the infrared monitoring device can monitor it in real time, thereby controlling the opening and closing of the built-in lamp 1.

[0042] Of course, in order to avoid the problem of damage caused by frequent opening and closing of the built-in lamp 1 due to frequent opening and closing of the door, the present invention particularly proposes the following improved concept, that is, after the refrigerator door is closed, the built-in lamp 1 is turned off with a delayed shutdown, so that the situation of frequent opening and closing of the built-in lamp 1 due to the time interval between two door openings can be avoided, thereby greatly extending the service life of the built-in lamp 1.

[0043] Based on the above-mentioned refrigerator built-in light on and off control method, the present invention also provides a refrigerator built-in light on and off control system, specifically, the refrigerator built-in light on and off control system includes the following components:

[0053] 4. Controller 5

[0054] The controller 5 is the control core of the refrigerator operation. The controller 5 is connected to the infrared monitoring component 4 and the circuit switch 3 by signal. The controller 5 receives the monitoring signal of the infrared monitoring component 4 for monitoring the opening status of the refrigerator door, and the controller 5 controls the circuit switch 3 according to the received monitoring signal.

[0056] Specifically, the infrared monitoring component 4 is embedded in the inner tank of the refrigerator body. The embedded installation method can realize the hidden installation of the infrared monitoring component 4, which can ensure the visual integrity of the inner tank of the refrigerator body and improve the aesthetics of the refrigerator.

[0057] Furthermore, a mounting groove is provided on a portion of the inner tank of the refrigerator body facing the inner tank protruding structure, and the infrared monitoring component 4 is clamped in the mounting groove.

[0058] The present invention provides a mounting shell on the outside of the infrared monitoring component 4, the infrared monitoring component 4 is airtightly packaged in the mounting shell, and the mounting shell is clamped in the mounting groove. Specifically, the mounting shell is made of antibacterial PVC material. Encapsulating the infrared monitoring component 4 in the mounting shell can improve the waterproof performance of the infrared monitoring component 4 and improve the reliability of the use of the infrared monitoring component 4.

[0059] Through the above structural design, the refrigerator built-in light on / off control system provided by the present invention uses an infrared monitoring component 4 to monitor the opening state of the refrigerator in real time, thereby controlling the opening and closing of the refrigerator built-in light 1. Infrared monitoring is a non-contact monitoring method.
