Fig. 3 is the schematic diagram of another embodiment of the power control apparatus of motor for washer of the present utility model and door lock.
The specific embodiment
With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model is wherein described.Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with figure and embodiment, the technical solution of the utility model is carried out to many-sided description.
For avoiding household electrical appliances to cause personal injury to consumer, international standard (as IEC60335-2-7 and EN60335-2-7 etc.) has had new requirement to the requirement of household electrical appliances safety, i.e. the rotating speed problem of opening the door of cylinder.In view of this requirement, the utility model designs a circuit for PTC door lock, drives when abnormal at door lock, realizes cylinder low speed or opens the door without rotating speed.
As shown in Figure 2: the power control apparatus of motor for washer and door lock comprises: electronic switch 11, motor-drive circuit 12 and door interlock switch.Electronic switch 11, motor-drive circuit 12 and the door interlock switch formation control main road of connecting successively, controls the main road formation loop of connecting with power supply.
Motor-drive circuit 12 can, according to specifically the selecting, arrange and design of motor, also can directly be connected on motor and control on main road.
Door interlock switch can be regular tap (locking a door after operation, door interlock switch closure) or PTC bimetal plate temperature controling switch etc.As shown in Figure 2, door interlock switch is PTC bimetal plate temperature controling switch, comprises PTC bimetal leaf element 14 and gauge tap 13, and PTC bimetal leaf element 14 is by closure and the disconnection of the height control gauge tap 13 of PTC temperature.It is the first circuit that gauge tap 13 is connected with described motor-drive circuit, the first circuit formation control main road in parallel with PTC bimetal leaf element 14; Electronic switch, control main road are connected with power supply and are formed loop.
Electronic switch refers to the running unit of utilizing power electronic devices to realize connecting and disconnecting of the circuit, at least comprises a controlled electronic valve device.Electronic switch 11 is in the time disconnecting, and motor-drive circuit 12 and door lock mechanism 15 will not worked.
The door interlock switch of door lock mechanism 15 is PTC bimetal plate temperature controling switch, is driven by PTC and bimetal leaf element 14.PTC, semistor, main characteristic is resistance-temperature characteristics, more high value is larger for temperature.PTC bimetal leaf element 14, is to utilize PTC variations in temperature to cause bi-metal plate deformed bending, makes the closing of contact or disconnection.
In the time that electronic switch 11 is activated, when PTC bimetal leaf element 14 is heated to running temperature, the bimetal leaf flexural deformation of PTC bimetal leaf element 14, drives and controls gauge tap 13 closures.After gauge tap 13 closures, motor-drive circuit 12 obtains electric, and motor enters predetermined running status.
According to an embodiment of the present utility model, in the time that motor-drive circuit 12 breaks down, control system disconnects electronic switch 11, motor dead electricity, the PTC bimetal leaf element 14 of door lock mechanism 15, also by dead electricity, needs about 40s because PTC is cooled to the temperature of unblanking, in this process simultaneously, motor speed can drop to and open the door below rotating speed, and the washing machine drum that now opens the door can not damage the person.When door lock mechanism 15 breaks down, control system disconnects electronic switch 11, and motor and door lock be dead electricity simultaneously, due to the time delay release characteristic of PTC door lock, can not cause personal injury.
