As one of improvement of the technical scheme: described control panel also comprises and is used to handle this distance measuring sensor signal and controls the unlatching of background light or the signal processing module of closing according to result.
As two of improvement of the technical scheme: described distance measuring sensor comprises infrared sensing module, signal amplification circuit module and the signal output module that connects successively, and this signal output module is connected with described control panel.
As three of improvement of the technical scheme: described signal processing module comprises: the infrared heat source monitoring module that is connected with the signal output module of distance measuring sensor, with the background light switching signal output module that is connected with background light; This infrared heat source monitoring module is used to receive the distance measuring sensor signal and itself and pre-set threshold value is compared, and background light switching signal output module is sent the instruction of opening or closing background light according to comparative result.
As four of improvement of the technical scheme: described control panel also comprises the time-delay closing module that is connected with described background light switching signal output module.
As five of improvement of the technical scheme: described pre-set threshold value scope is 0.5 meter to 3 meters.
For solving second technical problem, the present invention adopts second technical scheme:
A kind of control method of refrigerator display panel background light is characterized in that may further comprise the steps:
Step 1: survey zone to be detected with distance measuring sensor;
Step 2: distance signal between distance measuring sensor output human body and the refrigerator;
Step 3: after control panel receives this distance signal, itself and pre-set threshold value are compared;
Step 4: control panel is opened or is closed according to the comparative result control display panel background light of step 4.
As one of improvement of the technical scheme: described distance measuring sensor is an infrared distance sensor.
As two of improvement of the technical scheme: in step 4: then start time-delay closing device, parts or the module that is connected with background light simultaneously if background light is opened.
As three of improvement of the technical scheme: in step 2, the distance signal of described infrared distance sensor output is handled through amplifying; In step 3, described pre-set threshold value scope is 0.5 meter to 3 meters.
Compared with prior art, the beneficial effect of the present invention's first technical scheme is: owing to increased distance measuring sensor, make when human body enters its surveyed area, distance measuring sensor will convert the range information of user distance refrigerator to signal, and control panel then judges whether to open background light according to this signal.If the close together between signal explicit user that control panel obtains and the refrigerator, then need not the user further touches any button on the display board or opens refrigerator doors and can activate background light automatically, make things convenient for the user to observe information on the refrigerator display panel, for example internal temperature of refrigerator information etc.
Compared with prior art, the beneficial effect of the present invention's second technical scheme is: by detecting the distance between user and the refrigerator, judge whether to open the background light on the display board, can bring great convenience to the user so that the user need not to operate the background light that can activate on the display board in person thus.
