Description

Electronic timing controller for natural wind imitating electric fan

The utility model relates to a kind of electric fan control gear.

At present, on the market or the electric fan that people had can be divided into three class, a kind of is the low grade fan that can only control electric fan wind-force size; Second kind is that band mechanical timer (the longest 2 hours) installs the fitful wind electric fan of making the blocking oscillator composition with 555 integrated packages additional; The third is to finish timing, wind type, speed governing Full Featured high-grade electric fans such as (even can accomplish remote control) by a monolithic computer tablet.

It is a kind of with electronic timing that the purpose of this utility model is to provide, and the wind type curve set that reaches natural wind simulating is formed in a slice IC sheet, cooperates speed governing by key switch, produces the middle-grade electric fan control gear that six kinds of wind types change.

The utility model is to realize like this, be made up of key switch, OR circuit, voltage stabilizing circuit, control wiring, power supply, the third gear 1,2,3 that is characterized in having the key switch QK of speed governing and power supply open and close is connected to 1,2,3 points of main frame (motor D), the D of OR circuit respectively ₂, D ₃, D ₄On the negative electrode, and the control gate of formation ic chip supply voltage, D ₂, D ₃, D ₄Anode some back and current-limiting resistance R in parallel ₁Be connected to the voltage-stabiliser tube D of voltage stabilizing circuit after the series connection ₁Anodal, filter capacitor C ₁Negative pole, and C ₄One end, D ₁Negative pole and C ₁Anodal, C ₄Meet power supply N after the one end parallel connection and do public ground.The IC of control wiring is the special-purpose integrated packages of 14 pin, and 7 pin connect a 5V power supply, 14 pin ground connection, 1 pin and K ₁Be connected to a 5V power supply after the series connection, K ₂Be connected to-the 5V power supply C after 2 pin are connected ₂, C ₃Be connected in parallel on K respectively ₁, K ₂Two ends play preventing K ₁, K ₂The effect of successive signal.R ₂One is terminated at D ₂, D ₃, D ₄Anode, one is terminated at IC sheet 3 pin, its function is the usefulness of base when the standard frequency of 50HZ is sent into the IC sheet and done.IC sheet 4,5 pin are unsettled, the D in the control wiring ₅, D ₆, D ₇, D ₈Four light-emitting diodes tube cathodes are connected to IC sheet 6,8,9,10 pin respectively, show 4 respectively ^h, 2 ^h, 1 ^h, 0.5 ^hTiming, D ₅, D ₆, D ₇, D ₈After the anode parallel connection and resistance R ₃Series connection back ground connection.11,12 pin of IC sheet are the D of sending and receiving optical diode respectively ₉, D ₁₀Negative electrode, D ₉, D ₁₀Series resistor R after the anode parallel connection ₄Back ground connection, D ₉Show natural wind, D ₁₀Show normal wind, IC sheet 13 pin are the total output pins of control signal, series resistors R ₅The back joins with the bidirectional triode thyristor BCR control utmost point, the BCR minus earth, anode respectively with motor D 5 points, capacitor C ₅One end joins, C ₅The other end is connected on 4 of the motor D, and ic chip 14 joins with power supply N.When key switch QK disconnected, main frame (in the frame of broken lines) and control wiring did not all have electricity, and motor is in halted state.Arbitrary shelves in pressing QK, for example 1 grade (bottom gear), electric current can be from the N end through D ₁, R ₁, D ₄And flow to A end by QK, form the loop, voltage-stabiliser tube D ₁Two ends produce the 5V VDC, through C ₁, C ₄Carry out after the filtering for the IC sheet power supply of working.This moment, the IC sheet was in the initialization state.If press K ₂, the IC sheet promptly is in normal wind working state, promptly IC sheet 13 pin transfer low level to by original high level, have an about 10mA electric current from the BCR negative electrode beginning by the control utmost point, R ₅Flow to IC sheet 13 pin, this electric current is open-minded with controllable silicon BCR, so flow to 1 point to anode through 5 of motor D by controllable silicon BCR negative electrode, flows to A through key switch QK again and holds an alternating current (a.c.), and motor D is activated, fan rotation (as driving fan), luminotron tube D ₁₀Bright, show that IC sheet and electric fan are in normal wind running state.When clicking K again ₂The time, IC sheet 13 pin will reach the control to motor D by the control to BCR, and the running state of motor D and the change of state of IC13 pin are matched, and that is to say that electric fan is in the natural wind running state, simultaneously D ₉By intermittently luminous demonstration in 2 seconds.As clicking K again ₂, the IC sheet is in normal wind working state again, promptly by stop → mode of normal wind → natural wind → normal wind circulates.If 2 grades of pressing QK, then fan carries out the wind type by the middling speed wind speed and changes under the control of IC sheet, and in like manner as press 3 grades of QK, then fan changes by carry out the wind type at a high speed under the control of IC sheet.K ₁Be regularly given switch, if after QK presses, at first press K ₁, then IC exports normal wind state, and timing is then by 0.5 ^h→ 1 ^h→ 2 ^h→ 4 ^h→ not timing → 0.5 ^hState carry out conversion, wherein D ₈, D ₇, D ₆, D ₅Show 0.5 respectively ^h, 1 ^h, 2 ^h, 4 ^hTiming.

The utility model is with electronic timing, and natural wind simulating is integrated in a slice IC sheet, cooperates speed governing by key switch, produces the electric fan control gear that six kinds of wind types change, and is rational in infrastructure, easy for installation, is present a kind of more satisfactory middle-grade electric fan control gear.
