A kind of automatic control equipment of box house illuminating lamp
Technical field
The utility model relates to cabinet for home appliance intraoral illumination technical field, relates in particular to a kind of automatic control equipment of refrigerator inside illuminating lamp.
Background technology
Traditional refrigerator all has interior light, illumination lamp ignition during refrigerator open, whether open for detecting refrigerator doors, general refrigerator is installed a mechanical door switch at case courage side, at closing time, inner bag is pushed down door switch, and door switch disconnects, door switch closure then after opening the door, refrigerator controller is controlled opening or closing of interior light according to the status signal of door switch.The control of this conventional refrigerator interior light has a shortcoming, no matter when being bright by day or when dark at night, as long as refrigerator doors is opened, interior light is just lighted, and just wastes energy when bright so by day.
The utility model content
At the shortcoming in the above-mentioned refrigerator inside illuminating lamp control, the utility model provides a kind of automatic control equipment of box house illuminating lamp, comprise casing, door body, illuminating lamp and door switch, also comprise controller and photo-sensitive cell, described door body is hinged on the casing, and described door switch is installed on casing or the door body, described illuminating lamp and photo-sensitive cell are installed in the casing, described controller is installed on the casing, and its input connects door switch and photo-sensitive cell, and output connects illuminating lamp.Above-mentioned controller can be installed in the top of casing, and illuminating lamp is installed in the inside top of casing, and photo-sensitive cell can be installed on the rear board of box house or on the side panel.
The utility model can determine whether that needs light the illuminating lamp of box house according to the brightness of environment, has realized the intelligent automatic control switch, has reduced electrical equipment and has used energy consumption.
Description of drawings:
Fig. 1 is the utility model one example structure sketch;
Fig. 2 is another example structure sketch of the utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, the utility model provides a kind of automatic control equipment of box house illuminating lamp, comprise casing 1, door body 6, illuminating lamp 3 and door switch 5, also comprise controller 2 and photo-sensitive cell 4, described door body 6 is hinged on the casing 1, described door switch 5 is installed on the casing 1, also can be installed on the body 6 as required, described illuminating lamp 3 and photo-sensitive cell 4 are installed in the casing 1, described controller 2 is installed on the casing 1, its input connects door switch 5 and photo-sensitive cell 4, and output connects illuminating lamp 3.Wherein, photo-sensitive cell 4 will be installed on the position that can detect the brightness of casing interior lights, and it is installed on the rear board of box house in the present embodiment.
The utility model operation principle is: at first, the state of 2 pairs of door switch 5 of refrigerator controller is sampled, and detects door switch 5 by behind the signals of pushing down, and assert that then refrigerator doors 6 closed, is acted accordingly by refrigerator controller 2, closes interior light 3; When refrigerator doors 6 is opened, when refrigerator controller 2 detects door switch 5 energizing signals, sample the simultaneously signal of photo-sensitive cell 4 of refrigerator controller 2, when detecting refrigerator inside brightness and be lower than default value as photo-sensitive cell 4, assert that then refrigerator needs interior lighting, refrigerator controller 2 acts accordingly, open interior light 3, here default value can be known the brightness value of seeing things for the user, if photo-sensitive cell 4 detects refrigerator inside brightness when being higher than default value, assert that then refrigerator does not need interior lighting, open, also do not light interior light 3 even refrigerator controller 2 detects refrigerator doors 6.
As shown in Figure 2, also photo-sensitive cell 4 can be installed on the side panel in the casing 1, other structure is identical with above-mentioned embodiment, operation principle too, so just do not give unnecessary details at this.
The utility model can determine whether that needs light the illuminating lamp of box house according to the brightness of environment, has realized the intelligent automatic control switch, has reduced electrical equipment and has used energy consumption.
