Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of household electrical appliance are used integrated sensor, are that example is elaborated to be applied in the washing machine simultaneously the sensor that washings are carried out conductivity, turbidity and temperature detection.
As shown in Figure 1, integrated sensor comprises a housing 1, and the material of housing 1 adopts transparent plastic, and housing 1 comprises roughly cylindrical base portion 2, and the centre of extending 3, two extensions 3 of two extensions from base portion 2 has certain spacing.As shown in Figure 2, two extensions 3 roughly are half-cylindrical, the extension setting that is parallel to each other.
As shown in Figure 1; The base portion 2 of housing 1 is provided with a connector 4; Connector 4 is used for being electrically connected with computer program controller of washing machine; To sensor the isolation voltage of 5V is provided by computer program controller, simultaneously computer program controller also can through connector 4 receive by sensor to temperature signal, turbidity signal and conductivity signal.In housing 1, be provided with a PCB substrate 5, PCB substrate 5 is electric parts of this integrated sensor, and the circuit of dotted portion as shown in Figure 3 is arranged above the PCB substrate 5.
As shown in Figure 1; On PCB substrate 5, be connected with two battery lead plates 6, battery lead plate 6 passes the outside that housing 1 extends to housing 1 always from the inside of housing 1, and is as shown in Figure 2; On the relative position of two extensions 3, be respectively equipped with a battery lead plate locating slot 7; Two battery lead plates 6 are pegged graft respectively and are fixed in two battery lead plate locating slots 7, keep certain spacing between two battery lead plates 6, and the material of two battery lead plates 6 can adopt stainless steel, titanium alloy etc.Carrying out conductivity when detecting, two battery lead plates 6 extend in the washings of washing machine, and the washing electrical conductivity of water is converted by the variation of output voltage between two battery lead plates 6 and obtains.
As shown in Figure 3; Positive plate in the battery lead plate 6 is connected on the positive supply of computer program controller through 5 wirings of PCB substrate and connector 4; Minus plate is connected on the negative supply of computer program controller through connector 4 and sampling resistor R3, and the voltage at sampling resistor R3 two ends is the variation output signal of corresponding conductivity.
As shown in Figure 1; In two extensions 3, be respectively arranged with optical transmitter components 8 and light receiving element 9; Optical transmitter components 8 is a LED 1, and light receiving element 9 is sensitization triode TR1, and LED 1 and sensitization triode TR1 are electrically connected with PCB substrate 5.In two extensions 3, also respectively be provided with one be used to regulate light beam shadow shield 10, the measuring beam that is used to measure the washings turbidity is propagated between two extensions 3.When carrying out the turbidity detection; Two extensions 3 extend in the washings of washing machine fully, and according to the dirty degree of washings, the light that sends from light emitting diode makes light more concentrated through shadow shield 10; Again through the scattering of spacing washed water between two extensions 3; The shadow shield 10 that arrives opposite side makes light become more concentrated, is transmitted into the sensitization triode again, and the luminous flux of the light on the sensitization triode sensitive surface changes with the dirty degree of washings; The variation of luminous flux converts the variation of voltage to, measures the washings turbidity thus.The washings turbidity raises, and to the scattering enhancing of light, transmission weakens, and luminous flux will reduce.
