Embodiment of the present utility model:

(1) water supply process: with housing face-plate K ₃, K ₂Upwards dial, promptly connect with the circuit that single-phase motor supplies water, when setting needs the water supply liquid level to be lower than gauge B, C, relay J ₁, J ₂Will be because of triode BG ₂, BG ₁Be in cut-off state and can't work.Because J _2-1, J _1-2Constant close contact connect dc source, relay J ₃, J ₄Coil obtains the dc source adhesive.J _3-1Constant close contact disconnects, J is extinguished in indicator lamp D * 1 _3-2, J ₃The constant open contact closure, turn on pump indicator lamp DX ₂Promptly bright, single-phase motor water supply start at this moment is because J ₄Constant open contact is connected in parallel on J _2-1Constant close contact on and J ₄The effect of constant open contact self-locking, so when water level rises to B, C at 2, J ₂Relay adhesive, and J ₃, J ₄Relay is not discharge, lean on water to connect triode BG ₂Obtain bias current and saturation conduction by divider resistance, relay J ₂Coil just has electric current by adhesive, relay J ₂The constant open contact closure.At this moment low water stage indicator lamp D * ₃Bright, when water level rises to A (B) D point, connect by water.Triode BG ₁Obtain bias current and saturation conduction by divider resistance, relay J ₁Coil just has electric current by adhesive, at this moment J ₁The constant open contact closure, high water level indicator lamp D * ₄Bright, because of J _1-1Constant close contact disconnects, relay J ₃, J ₄Coil loses power supply and discharges later on, because J ₃, J _3-2, J _3-1The effect of constant open contact, just make single-phase motor stop to supply water, simultaneously turn on pump indicator lamp D * ₂Extinguish, termination of pumping indicator lamp D * ₁Show bright, when water level consumption drops to A (B) D two, relay J ₁Coil is because of BG ₁Triode changes cut-off state over to and can't work, and does not have power supply to pass through J ₁The coil of relay, J ₁Coil loses voltage and discharges, because J ₁The constant open contact effect, high water level indicator lamp D * ₄Extinguish J ₁Constant close contact is connected dc power cathode K _3-2Point is carried out the preparation of next turn on pump.When drawdown during to 2 of BC, single-phase motor starts turn on pump once more and supplies water, and control circuit repeats said process again.

(2) drainage procedure:

With K switch ₃To setting aside K switch ₂Upwards dial the on of whole draining circuit.When set needing the draining liquid level to be higher than 2 of BC, triode BG ₂Obtain bias current saturation conduction, J by divider resistance ₂Relay coil energising adhesive, J _2-2, J ₂The constant open contact closure is carried out the preparation of turn on pump, this moment low water stage indicator lamp D * ₃Bright, when the water level liquid level rises to 2 of A (B) D, triode BG ₁Obtain bias current and saturation conduction by divider resistance, relay J ₁Adhesive is by J _1-2, J ₁The constant open contact closure function connect power supply, simultaneously high water level indicator lamp D * ₄Bright, relay J ₃, J ₄Coil obtains also adhesive of dc source, J _3-2The constant open contact closure, J _3-1The disconnection of constant close contact make turn on pump indicator lamp D * ₂Bright, termination of pumping indicator lamp D * ₁Extinguish.And J ₃The closed single-phase motor of constant open contact begins the turn on pump draining.When the water level liquid level drops to A (B) D gradually, J ₃, J ₄Still adhesive of relay because J ₄Constant open contact be connected in parallel on J _1-2Constant open contact on, J ₄Constant open contact place self-locking state, when the water level liquid level is lower than 2 of A (B) D, triode BG ₁Change cut-off state over to and can't work relay J ₁Coil does not have electric current to pass through to discharge, because J ₁Constant open contact effect high water level indication D * ₄Extinguish.Triode BG when the water level liquid level is lower than B, C at 2 ₂Change cut-off state over to and can't work relay J ₂Coil loses electric current and discharges, at this moment J ₃The constant open contact effect, single-phase motor stops draining, because J ₂, J _3-2, J ₃The constant open contact effect, be lower than water level indicator light D * ₃, termination of pumping indicator lamp D * ₁Bright.When the water level liquid level rises to 2 of BC again, triode BG ₂Start working relay J again _2-2The constant open contact closure, carry out the preparation of next turn on pump draining, control circuit will repeat said process again.

If the use threephase motor,, pass through F as long as threephase motor is stopped in button and the starter button separated ₁, F ₂Point connects starting button constant open contact, K switch ₂Set aside and get final product.

K switch in the water level switch of automatic water-supply draining of the present utility model is icing easily design of water pump in winter.Heater is handled the fusing ice cube under the K switch, with the safe handling motor.K switch is upwards dialled, and can force the single-phase motor water supply and drainage, and it is the hand switch that designs under the special situation in order to deal with.

To sum up, the utility model has reached fully for, discharge level automatic control function, and circuit structure is simple, wiring and operation is all very convenient, highly sensitive, volume is little, long service life, cost are low, the goal of the invention that reached expection.
