Abstract
The utility model provides a refrigerator sterilizer fresh appliance with time control, which comprises mainly an ultraviolet lamp, an automatic control device of time and a time display screen. The ultraviolet lamp and an LM8363 time control integrated circuits are arranged in the cold-storage container of a refrigerator, the power supply source of the ultraviolet lamp and the LM8363 time control integrated circuits is connected with the lighting circuit of the cold-storage container, and a time control spin button and the time display screen are arranged out of the door of the refrigerator. The operating time of sterilizing can be selected and regulated according the need of a user, the ultraviolet lamp can be on and off automatically through the controlling of the automatic control device of time. Ultraviolet rays and ozone are generated when the ultraviolet lamp works, thereby, the goal of sterilizing and preserving is achieved.
Description
The utility model relates to a kind of refrigerator sterilization fresh-keeping device with time control.
Existing refrigerator sterilization fresh-keeping device has the ultraviolet sterilization that utilizes uviol lamp to produce, but is not with timed unit, can not control the sterilization operation time automatically.
Task of the present utility model provides a kind of refrigerator sterilization fresh-keeping device with time control.
Task of the present utility model is finished by following scheme: a uviol lamp and a LM8363 time control integrated circuit are housed in the refrigerator cold-storage case, and its power supply connects with refrigerating box intraoral illumination circuit, and refrigerator doors is equipped with time control outward regulates button and time display screen.
Be further described below in conjunction with accompanying drawing.
Fig. 1 is the basic circuit diagram of utility model.
Fig. 2 is the profile installation diagram of utility model.
Uviol lamp ［ 7 ］ and LM8363 time control integrated circuit ［ 2 ］ are installed in the refrigerating box, its power supply connects with the refrigerating box lighting circuit, time display screen ［ 1 ］ and time control are regulated button ［ 3 ］ and are installed in outside the refrigerator doors, L1, R1, R7, D1, D2, D3, D4, D5, D6, C1, C2 and three-terminal regulator block ［ 10 ］ are formed ［ 1 ］, ［ 2 ］, ［ 4 ］ power supply circuits, C3 and R6 constitute integrating circuit, ［ 4 ］ and the warning of ［ 2 ］ output, the pass input of reporting to the police links to each other, ［ 4 ］ connect ［ 5 ］, ［ 6 ］, D7, R8, the on-off circuit that R4 forms, R5 connects 26 pin of ［ 2 ］, 14 pin and the C3 of another termination ［ 4 ］, the other end of C3 links to each other with R6, the other end ground connection of R6, R2 connects 29 pin of ［ 2 ］, 3 pin of another termination ［ 4 ］ of R2, R3 connects 27 pin of ［ 2 ］, the other end links to each other with 2 pin of ［ 4 ］, ［ 4 ］ 4 pin are connected with 15 pin, ［ 4 ］ 2 pin also link to each other with R4, the base stage of another termination ［ 5 ］ of R4, ［ 5 ］ emitter stage links to each other with 13 pin of ［ 4 ］ and ground connection, ［ 5 ］ colelctor electrode is connected with R8, one end of the winding of another termination ［ 6 ］ of R8 and the anode of D7, the negative electrode of another termination D6 of the winding of ［ 6 ］, the negative electrode of D7, ［ 4 ］ 16 pin; ［ 4 ］ 8 pin ground connection, in the power supply circuits of uviol lamp ［ 7 ］, the normally opened contact that is connected in series ［ 6 ］ is held with dividing altogether, and time adjusting and time of fire alarming that time control adjusting button ［ 3 ］ connects ［ 2 ］ are provided with end, the negative electrode of another termination D6 of ［ 3 ］.After regulating ［ 3 ］, reserving the opening and closing time, the opening time one arrives, ［ 2 ］ an output set of pulses by integrating circuit ［ 9 ］, becomes a pulse, enter ［ 4 ］, the output output high level of ［ 4 ］, ［ 5 ］ conducting, ［ 6 ］ adhesive, switch J1-1 ［ 8 ］ closure, the power supply of connection ［ 7 ］, start working ［ 7 ］, arrive when the shut-in time one, ［ 2 ］ an output set of pulses becomes a pulse by ［ 9 ］, enters ［ 4 ］, its duty is changed, output low level, end ［ 5 ］, and ［ 6 ］ discharge, ［ 8 ］ disconnect, ［ 7 ］ quit work.When uviol lamp ［ 7 ］ is worked, produce ultraviolet ray and ozone, have very strong bactericidal action, thereby reach the effect of sterilization fresh-keeping.
During use, the user can select the sterilization operation time arbitrarily as required, only need press time control and regulate button and regulate, and by the time control integrated circuit, the uviol lamp in the refrigerator can then be opened work automatically and closes automatically by the time requirement, and is very convenient.
