Abstract
The utility model provides a multifunctional remote-controlling all-shutdown controller for household electric appliances, which is composed of an outer shell, a printed circuit board, a supply socket, a power plug, a functional switch, a sampling circuit, a commutation filtering circuit, a control relay, an over-voltage protection circuit, etc. The utility model can realize the purposes of remote-controlling all-shutdown, timing all-shutdown, automatic protection of power failure and over-voltage protection.
Description
The utility model relates to a kind of domestic electronic appliances, specifically, is a kind of and the matching used multifunction remote-control household electrical appliances of remote control household electrical appliances complete closedown controller.
At present nearly all commercially available household remote shutdown all is DC power supply or the part AC power of turning off in the machine, and AC power or its part are still switched on, still consume certain power, and go down to damage easily electrical equipment for a long time, not only dangerous but also power consumption, so after each electrical equipment is used, need the shutdown unplugg.
The purpose of this utility model just provides a kind of multifunction remote-control household electrical appliances complete closedown controller; utilize timing halt signal in the former machine and the remote control pause button on the remote controller to realize regularly complete closedown and remote control complete closedown, can realize cutting off the power supply automatic protection, overvoltage protection, prevent the frequent switching on and shutting down of children.
The purpose of this utility model is achieved in that when switch of the present utility model places remote control complete closedown state, click the remote control Pause key on the former set remote-controller, perhaps time is up for the timing shutdown in the electrical equipment, former machine promptly changes halted state over to by normal operating conditions, the power that is consumed significantly reduces, thereby pressure drop also reduces greatly on the sample resistance, and AC power has been cut off in normally adhesive and disconnecting of relay.When switch of the present utility model places the remote control halted state, the remote control time-out of former machine and the function that remote control is opened have been recovered.Be under the complete closedown state in this utility model; when having a power failure suddenly appears in AC power; relay electric-loss disconnects; even at this moment AC power is recovered normal electrical equipment and also can not switched on; unless remove out machine again No. one time; can effectively avoid like this damaging, realize the outage purpose of protection automatically because of the frequent power on/off of electrical equipment.When line voltage makes voltage (interchange, direct current or pulse voltage) when being higher than 360V because of certain reason, piezo-resistance is the earial drainage state, thereby makes the power supply crest voltage of electrical equipment be no more than 360V, thereby can prevent that electrical equipment from causing damage because of overvoltage.Small children is wanted necessary two the above switches of proper operation (mains switch or pause button on supply socket switch, controller function switch, the electrical equipment) of turn on, and any one is made mistakes and all misses one's aim.
The utility model adopts the principle of voltage sampling and overvoltage earial drainage, and is simple in structure, and stable performance is practical.
Electrical schematic diagram of the present utility model is provided by following embodiment and accompanying drawing.
Accompanying drawing is the electrical schematic diagram of the utility model multifunction remote-control household electrical appliances complete closedown controller.
Describe details of the present utility model and working condition in detail below in conjunction with accompanying drawing:
The utility model comprises shell, printed substrate, supply socket, attaching plug, functional switch K, rectifier diode D, relay J, filter capacitor C, sample resistance R
1, current-limiting resistance R
2, LED, piezo-resistance MYL-360, fuse F.As shown in drawings, during start, K closes, the two cutter K of K
1-1, K
1-2Connect, power supply indicator LED is bright, when electrical equipment is in normal operating conditions, and R
1Last generation pressure drop, this pressure drop become approximate direct voltage by diode D halfwave rectifier, capacitor C filtering makes J adhesive, J
1-1, J
1-2Close in two contacts, at this moment the state of this utility model is the remote control halted state of electrical equipment, and at this moment, if disconnect K, this utility model promptly enters remote control complete closedown state.When utility model was in the complete closedown state, regularly time is up to click Pause key on the controlled domestic electrical equipment remote controller or controlled household electrical appliances, and electrical equipment changes halted state immediately over to, and the power that is consumed reduces greatly, and R flows through
1Electric current also reduce R greatly
1The pressure drop of last generation also reduces greatly, thereby J discharges J
1-1, J
1-2Disconnect, cut off whole AC power, the LED lamp extinguishes.When supply voltage surpassed 360V because of certain reason, piezo-resistance MYL-360 was the earial drainage state automatically, and fuse F fusing prevents that effectively overvoltage from damaging television set.
The selection of components and parts: D is withstand voltage more than or equal to 25V, electric current rectifier diode such as the 1N4004 more than or equal to 1A, sample resistance R in the utility model accompanying drawing
1Span be 10 Ω---200 Ω, determine concrete value according to the power of controlled electric appliance.The value of C should be more than or equal to 220 μ F, and is withstand voltage more than or equal to 16V.J selection work voltage is 3V or the 6V contact current relay more than or equal to 1A, as 4099 or JRx---13F etc.R
2Value is 30K Ω---68K Ω, LED are common light-emitting diode.MYL---360 is maximum continuous voltage 230
The lightning protection piezo-resistance of nominal varistor voltage 360V.F is the 2A fuse.K is the double-pole switch of contact current more than or equal to 1A, and also the single knife switch of available same parameter replaces.
The utility model is applicable to that remote control colour TV set, black-and-white TV, video tape recorder, electric fan etc. have the household electrical appliance of remote control time-out or timing shutdown function, can be used as independently product and the supporting use of these class remote control household electrical appliances, also can be loaded in the machine to use.This utility model manufacturing technique requirent is low, and equipment is few, and cost is low, is with a wide range of applications.
