Description

Multi-purpose household electric appliance controller

The utility model relates to a kind of active element circuit arrangement with the work of electronic switch mode that adopts the electric pulse technology, specifically is meant a kind of household electrical appliances modulator of using more.

Now some household electrical appliances is carried out the accessory device of work regulation and control, as electric fan timing and speed regulating device, illuminating lamp light modulating device, and electric blanket temperature adjustment and timing device etc., the problem that their exist is: (1) is special designs, thereby versatility is poor; (2) generally adopt thyristor to exchange switch, because the components and parts of series connection are many, the pressure drop loss is bigger, generally about 10VAC, does not therefore reach maximum output when rated voltage, does not then reach maximum wind power when load is electric fan; (3) thyristor exchanges switch power cutoff fully, promptly be to have no progeny in this alternating-current switch pass, a lower voltage is still kept at the load two ends, making has electric current to flow through in the load, only because brownout, be unlikely to make the load operate as normal, but exist the certain energy loss really like this; (4) generally adopt the step superposing type regularly, therefore regularly can not regulate by continuous stepless, though precision is better, the adjusting span is too big, and the leeway that makes the user select is too little.

The purpose of this utility model, but provide that a kind of versatility is strong, voltage-regulation wide ranges, loss of energy, timing are not long and continuous stepless is regulated when not working household electrical appliances modulators of using more.

Referring to Fig. 1 the utility model electricity functional-block diagram, its solution is, circuit part has D.C. regulated power supply (1), it supplies with startup and continuous stepless is regulated long timing circuit (2), fitful wind and ventilation timing circuit (3) and controlled intermediary circuit (4) with direct-current working volts, also has a working mode selection K switch ₁, K ₁Moving contact K _1-0Link to each other K with the input of control intermediary circuit (4) ₁Two fixed contact K _1-1And K _1-2Output with startup and continuous stepless adjusting long timing circuit (2) and fitful wind and ventilation timing circuit (3) joins respectively, and control intermediary circuit (4) contains relay J ₁, by its normal opened contact J _1-1Thyristor voltage regulation circuit (5) is carried out switch control.

The utility model with foregoing circuit structure should insert the 220V electric main with D.C. regulated power supply (1) when concrete work, be connected on the 220V electric main after also external family electric loading (6) and thyristor voltage regulation electrical equipment (5) being in series simultaneously.If with K switch ₁Place K _1-1Shelves then start and continuous stepless is regulated startup and the timing signal that long timing circuit (2) will manually perform regularly adjusting and passed through K ₁Give control intermediary circuit (4), by its relay J ₁Normal opened contact J _1-1Control thyristor voltage regulation circuit (5) is connected with external family electric loading (6), simultaneously also by adjusting to adjustment element in the thyristor voltage regulation circuit (5), make external family electric loading (6) obtain continuously adjustable operating voltage, and after the scheduled time of working, regulate long timing circuit (2) by startup and continuous stepless and send signal, make thyristor voltage regulation circuit (5) no-voltage export to external family electric loading (6).

External family electric loading can be an electric fan, also lighting bulb, electric blanket, electric heater etc., thereby can realize the stepless speed regulation of electric fan and regularly running, realize the stepless dimming and regularly light on and off of bulb, and stepless accent heat and the timing switch of realizing electric blanket and electric heater.

K ₁K _1-2Shelves are specialized in the electric fan load and are used.With K ₁Place this shelves, fitful wind and ventilation timing circuit (3) will manually perform the timing fitful wind of regularly regulating or the signal that regularly ventilates passes through K ₁Give control intermediary circuit (3), by its relay J ₁Normal opened contact J _1-1Control thyristor voltage regulation circuit (5) is connected with external family electric loading (6), simultaneously also can be by adjusting to adjustment element in the thyristor voltage regulation circuit (5), carry out air quantity with matching and regulate, little fitful wind (natural wind simulating) when big when making electric fan produce air quantity.

The utlity model has following advantage and good effect: (1) highly versatile.The energy one-object-many-purposes is applicable to multiple household electrical appliances such as electric fan, bulb, electric blanket, electric heater; (2) voltage-regulation wide ranges.Owing to adopt relay J ₁Normal opened contact J _1-1The break-make of control thyristor voltage regulation circuit, so reduced the pressure drop loss, make this device when rated voltage 220VAC, voltage adjusting range is at 80VAC-217VAC, because voltage adjusting range is wide and level and smooth, therefore can carry out smooth stepless speed-regulating to all kinds of electric fans, can keep the original maximum wind power of electric fan basically, can below 125VAC, obtain the gentle breeze that general electric fan does not have; Loss of energy not when (3) not working, this also is that making household electrical appliances not load on when working can cut off the electricity supply fully, thereby has avoided unnecessary electric energy loss owing to adopt relay J; (4) continuous stepless is regulated long setting (being generally error ± 15% 15 minutes-6 hours) regularly, greatly facilitates the user.Forget the pass electric fan when it can avoid the people to leave, also satisfied the needs that when falling asleep hot summer electric fan carried out long timing simultaneously; (5) setting of fitful wind and ventilation timing function, make different fitful winds satisfy different physique persons' needs, ventilation function then makes things convenient for the user to start ventilating fan running a few minutes (as 3-4 minute) automatically, the indoor timing that is applicable to south, north of china in winter family is ventilated, also adjustable many ventilating fans are used for warehouse and place that all kinds of needs regularly ventilate.

Below in conjunction with drawings and Examples the utility model is further specified.
