Abstract
The utility model discloses a full-automatic controller for electric mattress. The operating state of full-automatic control for the electric mattress can be realized through photoelectric control and temperature control. The full-automatic controller for electric mattress is characterized in that the controller comprises a photoelectric control circuit, a temperature control circuit and an executive circuit. The photoelectric control circuit adopts a light sensitive element as the body. The temperature control circuit adopts a heat sensitive triode as the body. The executive circuit is connected with the output ends of the photoelectric control circuit and the temperature control circuit. The utility model has the advantages of simple structure, which is suitable for any finished product or self-made electric mattresses (or electric heating blankets).
Description
The utility model relates to the automatic temp controller of a kind of electric mattress (or electric blanket).
Existing electric mattress controller all is only limited to temperature control, does not have the automatic open function of apparent time.People also need to turn off the electric mattress power supply daytime in actual use, and connect night again, and are comparatively loaded down with trivial details really, sometimes because of forgetting that turning off the electric mattress power supply wastes electricity daytime, also worries on fire; Sometimes go out evening to scurry the door do not plug electric mattress, when coming back on the bed a slice ice-cold, be difficult to go to bed and fall asleep.This class electric mattress controller uses some inconvenience.
The purpose of this utility model is, controls automatically by automatic control of photoelectricity and temperature, realizes the Automatic Control to the electric mattress operating state, and makes the height of thermostat temperature arbitrarily to adjust.
The utility model is made up of electric mattress, power supply and control circuit.Control circuit comprises that the light-sensitive element that converts light signal to the signal of telecommunication is the photoelectric control circuit of main body; The temperature-sensitive triode that temperature signal is converted to the signal of telecommunication is the automatic temperature control circuit of main body, and the executive circuit that links to each other with above-mentioned two circuit output ends.The executive component relay contact joining is in the electric mattress loop, thereby realization is to the Automatic Control of electric mattress apparent time and constant temperature.
The utility model has following accompanying drawing.
Fig. 1 is the utility model structured flowchart.
Fig. 2 is circuit theory diagrams of the present utility model.
With reference to the accompanying drawings, the utility model is further described.
Power unit of the present utility model (1) is made up of transformer B, bridge rectifier ZL, filter capacitor Co and voltage-stabiliser tube Do; Photoelectric control circuit (2) is by phototriode T5, triode T2, biasing resistor R3 and R4, and backup circuit breaker K forms; Temperature-control circuit (3) is regulated resistance R w by temperature-sensitive triode T4, constant temperature point, and triode T1, biasing resistor R1, R2 and temperature control diode D1 form; Executive circuit (4) is by capacitor C and diode D2, D3, and triode T3 and relay J are formed.
220 volts of civil powers supply control circuit one direct current power supply after transformer B step-down, rectification ZL, capacitor C o filtering and voltage-stabiliser tube Do voltage stabilizing.In photoelectric control circuit (2), T5 is a phototriode, can place bed to go up or be placed on and face toward glass on the window, on daytime, the light that photosensitive tube T5 accepts is stronger, the electric current of supplying with triode T2 is bigger, the T2 saturation conduction, B ' some potential pole is low, and T3 ends, relay J discharges, and electric mattress (5) outage is not heated.Temperature-sensitive triode T4 resistance is bigger in temperature-control circuit this moment (3), and the electric current of supplying with T1 is less, and A ' some current potential is higher, and diode D1 instead ends partially, does not influence the release condition of relay.Night, photosensitive tube T5 accept light a little less than, the electric current of supplying with T2 is very little, T2 almost ends, B ' some current potential is higher, the adhesive of T3 turn-on relay, electric mattress energising heating.Raising gradually along with the electric mattress temperature, the resistance that is placed on the temperature-sensitive element T4 under the electric mattress reduces gradually, the electric current of T1 increases gradually, and A ' some current potential descends gradually, when dropping to A ' some current potential and being lower than B ' 0.7 volt, the D1 conducting, B ' some current potential is also with A ' corresponding decline, and when reducing to certain value, the T3 electric current in the executive circuit (4) is very little, relay J discharges, electric mattress outage stopping heating.Temperature begins slowly to descend, and it is big that the resistance of T4 becomes again gradually, and the electric current of T1 reduces gradually, and A ' some current potential improves gradually, and B ' some current potential also improves thereupon.The electric current of T3 increases gradually, until relay adhesive again, and the electric mattress heating of switching on again.So periodic duty makes electric mattress constant on certain temperature.Adjust Rw and can change thermostat temperature, if turn the resistance of Rw down, the shunting increase to T1 has improved the constant temperature point, otherwise constant temperature point reduces.Because germanium triode (being T4) is very responsive to temperature, thus very sensitive during as temperature-sensing element, promptly improved sensitivity, simplified circuit structure and reliable operation again.
Because the result of photo-electric control, daytime, electric mattress was not worked, if need use electric mattress by day, only needed to connect backup circuit breaker K and got final product.
Capacitor C in the executive circuit (4) and the effect of diode D2 are to eliminate the flutter phenomenon of relay when adhesive discharges critical condition.
The utility model adopts above-mentioned photo-electric control and temperature controlled Combination Control mode, has realized that electric mattress opens night automatically, and close daytime automatically, brings great convenience to the user; Regulate the thermostat temperature of electric mattress as required voluntarily, can allow the user feel more comfortable.
The utility model is applicable to any finished product or self-control electric mattress (or electric blanket).
