Abstract
The utility model provides a convenient energy-saving protector for the refrigerator, which is composed of a control circuit and an operating button serially connected with the control circuit. The convenient energy-saving protector for the refrigerator can be made into a socket form and has the delaying function and the over-voltage and over-current protective function of the generic protector, and the control circuit is automatically switched off when the user unplugs to make the refrigerator stop running. The convenient energy-saving protector for the refrigerator has the advantages of convenient operation, low cost and power-saving.
Description
The refrigerator protector of selling on the present domestic market; though refrigerator is had voltage stabilizing, time-delay and under-voltage or overvoltage protection; but no matter whether refrigerator moves; each control element of its protector itself is all in energising work; will definitely influence the useful life of each control element like this; and the refrigerator protector of selling in the market all does the apparatus for converting formula, if want when refrigerator does not move it is taken off and inconvenient, and cost is also high.
The purpose of this utility model provides and does not a kind ofly require operation and when pulling out plug when refrigerator; the also automatic cold refrigerator protector of the control circuit of this protector own; and the whole protecting device is made a socket pattern, make this protector except that time-delay that general protector had and under-voltage or over-voltage protecting function, also have easy to use, cost is low, power saving is anti-.
Control circuit of the present utility model shown in accompanying drawing (1), by step-down filter rectification network R, electronic control component network E, relay J and the action button A that is connected on the control circuit form.The whole protecting system all is contained in the protector outer casing (2) of a band socket.
Operation part of the present utility model shown in accompanying drawing (2), by plug (1), protector outer casing (2); action button contact (3), back-moving spring (4), action button contact (5); conducting sheet in socket (6), contact insulation button (7), plug pin (8) is formed.
The utility model is achieved in that when requiring the refrigerator operation; refrigerator plug (1) is inserted in the socket aperture of protector outer casing (2); plug during insertion (1) downwards promotes the contact button (7) that insulate action button contact (5) is contacted with action button contact (3); i.e. 2 connections of C, D among the figure make the energising work of whole protecting system.
When requiring refrigerator not move; refrigerator plug (1) is transferred to protector outer casing (2); at this moment back-moving spring (4) upwards promotes action button contact (5) automatically and disconnects with action button contact (3); i.e. 2 disconnections of C, D among the figure; make the whole system dead electricity; because conducting sheet in socket (6) has certain pressure to plug pin (8), so just can finish above order as long as choose suitable spring reset power.
This protection system makes it to have by choosing suitable step-down filter rectification network and electronic control component network and relay J:
One, can both automatic disconnection relay normally open contact J when civil power is below or above refrigerator permission voltage;
Two, when instantaneous power failure and incoming call took place, circuit can be delayed time and be powered to refrigerator in 5～10 minutes again.
This utility model is specially adapted to the electrical equipment of seasonal electricity consumption or intermittent electricity consumption, can be widely used in the improper area of civil power.
Claims (1)
- A kind of convenient and energy-saving refrigerator protector; it is by the filter rectification network R that is contained in protector outer casing (2); electronic control component net E; relay J; action button contact (3); action button contact (5); contact insulation knob (7); back-moving spring (4); conducting sheet in socket (6) and plug (1) and plug pin (8) are formed; it is characterized in that having on the action button contact (5) contact insulation (7), under have back-moving spring (4) to play control action button contact (5) respectively to contact with action button contact (3) on being connected on control circuit or disconnect.
