Abstract
The invention relates to a refrigerator door monitor, which belongs to the technical field of protection alarm for articles and appliances for daily life and comprises a sensing host and a magnetic strip. The sensing host and the magnetic strip are independent from each other, a conducting iron plate with a spring, a power contact, a button battery, a timing and controlling device and a voice unit are arranged in the sensing host, the timing and controlling device is connected with the power contact by the voice unit, also connected with the power contact by the button battery and further connected with the conducting iron plate by the spring, and a strong magnet is disposed in the magnetic strip of the conducting iron plate. The refrigerator door monitor is simple and convenient in use, and the problem that a refrigerator door is improperly closed or forgotten to be closed is solved.
Description
Technical field
The present invention relates to a kind of refrigerator doors watch-dog, belong to daily necessities apparatus protection alarm technique field.
Background technology
When in refrigerator, taking food, if refrigerator doors is not closed, or forget and shut that can cause that cold air flows out in the refrigerator, not only electricity wasting possibly cause food spoilage in the refrigerator simultaneously.This watch-dog can solve the problem that the pass was not closed or forgotten to refrigerator doors.
Summary of the invention
A kind of refrigerator doors watch-dog of the present invention, purpose are exactly to above problem, provide a kind of easy to use, can solve the refrigerator doors watch-dog that the pass was not closed or forgotten to refrigerator doors.
The technical scheme of a kind of refrigerator doors watch-dog of the present invention: this watch-dog is made up of induction main frame and two independent parts of magnetic stripe.Form by conduction iron plate, power contact, button cell, timing and controller, the voice unit (VU) of band spring in the induction main frame; Timing is connected with power contact through the voice unit (VU) spring with controller, and timing is connected with power contact through button cell with controller, and timing is connected with the conduction iron plate through spring with controller; In the conduction iron plate magnetic stripe powerful magnetite is arranged.The induction main frame uses adhesive sticker to be installed on the refrigeratory body door limit, and magnetic stripe utilizes adhesive sticker to be installed on the refrigerator doors.After door closed well, induction main frame and magnetic stripe were horizontal alignments, and close (2-5 millimeter).Under the magnetic attraction of magnetic stripe, the band spring conduction iron plate in the induction main frame is attracted to the magnetic stripe direction, and conduction iron plate and power contact break off.After refrigerator doors was opened, magnetic stripe was far away apart from change with the conduction iron plate in the induction main frame, and the conduction iron plate loses its reliss, and under the effect of spring, links with power contact, causes circuit closed circuit.Timing and controller in the induction main frame pick up counting.If surpass certain hour (40-60 second), circuit is still closed circuit (be that refrigerator doors is not closed, magnetic stripe is not got back to the origin-location yet, and the conduction iron plate still connects together with power contact), and the induction main frame sends alarm sound, and reminds people is closed refrigerator doors.Alarm sound continues to play, till magnetic stripe attracts the conduction iron plate in the induction main frame to come to cause circuit breaker once again.
Beneficial effect:
1, use two independent sectors of magnetic stripe and induction main frame to form watch-dog.
2, the induction main frame is installed on the refrigeratory body door limit, and magnetic stripe is installed on the refrigerator doors.
3, refrigerator doors is closed when good, and induction main frame and magnetic stripe are apart from extremely near.Under the magnetic stripe magnetic attraction, the conduction iron plate in the induction main frame is attracted power and draws back from power contact, causes the induction host circuit to open circuit.
4, after refrigerator doors was opened, the conduction iron plate in the induction main frame lost the attraction of magnetic stripe, and pop into position is put under spring action, connected with power contact, and circuit becomes closed circuit, and timing and controller pick up counting.
5, after through one rational period, the inductive switch circuit is still when closed circuit, and timing and controller are play from voice unit (VU) and reminded sound.
Description of drawings
A kind of refrigerator doors watch-dog of Fig. 1 the present invention structural representation.Form by induction main frame 1, magnetic stripe 2, timing and controller 3, spring 4, button cell 5, voice unit (VU) 6, power contact 7, conduction iron plate 8, magnetite 9.
The specific embodiment
In conjunction with diagram a kind of refrigerator doors watch-dog of the present invention done as follows and to further specify.
A kind of refrigerator doors watch-dog of the present invention is made up of with 2 two independent parts of magnetic stripe induction main frame 1; Form with controller 3, voice unit (VU) 6 by conduction iron plate 8, power contact 7, button cell 5, the timing of band spring 4 in the induction main frame 1; Timing is connected with power contact 7 through voice unit (VU) 6 with controller 3, and timing is connected with power contact 7 through button cell 5 with controller 3, and timing is connected with conduction iron plate 8 through spring 4 with controller 3; In conduction iron plate 8 magnetic stripes 2 powerful magnetite 9 is arranged.Induction main frame 1 uses adhesive sticker to be installed on the refrigeratory body door limit, and magnetic stripe 2 utilizes adhesive sticker to be installed on the refrigerator doors.After door closed well, induction main frame 1 was horizontal alignments with magnetic stripe 2, and close (about 2-5 millimeter).Under the magnetic attraction of magnetic stripe 2, the band spring 4 conduction iron plates 8 in the induction main frame 1 are attracted to magnetic stripe 2 directions, and conduction iron plate 8 breaks off with power contact 7.After refrigerator doors was opened, magnetic stripe 2 was far away with the conduction iron plate 8 distance changes in the induction main frame 1, and conduction iron plate 8 loses its reliss, and under the effect of spring 4, links with power contact 7, causes circuit closed circuit.Timing and controller 3 in the induction main frame 1 pick up counting.If surpass certain hour (40-60 second), circuit is still closed circuit (be that refrigerator doors is not closed, magnetic stripe 2 is not got back to the origin-location yet, and conduction iron plate 8 still connects together with power contact 7), and induction main frame 1 sends alarm sound, and reminds people is closed refrigerator doors.Alarm sound continues to play, till magnetic stripe 2 attracts the conduction iron plate in the induction main frame 18 to come to cause circuit breaker once again.
