Abstract
The utility model which is provided with the photoelectric control relates to a reminding and alarming device for the closing of the door of a refrigerator, comprising a light-sensitive switch circuit, a delaying flip-flop circuit and a musical alarm circuit. The overlaying of the non-drying glue is adhered on the side surface or the bottom surface of the reminding and alarming device, and a light-sensitive spy hole is arranged on the housing of the reminding and alarming device, and the light source of the illumination lamp of the refrigerator is used as the photoelectric control switch. The reminding and alarming device is fixed or installed near the illumination lamp of the refrigerator, the music played by the utility model can remind a user not to forget to close the door of the refrigerator when the door is opened for some time, and the purpose of saving the electricity is realized.
Description
The utility model relates to a kind of suggestion device of closing the door of installing or being placed in the refrigerator and belongs to warning device.
Refrigerator time of opening the door is long more, and power consumption is many more.Close the door if forgotten, also might cause the damage of compressor, prevent to forget and close the door in order to shorten the time of opening the door, the purpose of this utility model has been to provide a kind of can install the suggestion device of putting or be placed on refrigerator inside, after refrigerator opened the door a period of time, this device was reminded the user not forget by music and is closed the door.Characteristics of the present utility model are to utilize the refrigerator illuminating lamp as the photo-electric control light source, the work of employing dc source, only need be placed on this device or be fixed near the illuminating lamp with the adhesive sticker veneer, photosensitive peephole is arranged on the shell of this device, with the peephole alignment light source, get final product operate as normal, do not need refrigerator is changed, easy to use, working stability.
Device of the present utility model is by power supply, photosensitive circuit, and several parts of delay circuit and music integrated circuit are formed, and to open illuminating lamp bright when the door of refrigerator, the photosensitive tube conducting of this prompting device, BG
1-3The delay circuit of forming is started working, and after after a while, as not closing the door, suggestion device will be played music and remind the user in time to close the door, as has forgotten to close the door, and melody can constantly play again, and reminds the user to close the door.Shut behind the door, illuminating lamp goes out, and photosensitive circuit disconnects, and melody stops.
Embodiment below in conjunction with description of drawings the utility model device.
