Describe the leak water detdction circuit for household electrical appliance according to the utility model embodiment with reference to the accompanying drawings, and there is insulating pot and the control method thereof of this leak water detdction circuit.
First the leak water detdction circuit for household electrical appliance of the utility model embodiment is described.
Fig. 1 is the block diagram of the leak water detdction circuit for household electrical appliance according to an embodiment of the present utility model.As shown in Figure 1, the leak water detdction circuit 100 for household electrical appliance of the utility model embodiment comprises detection module 10, acquisition module 20 and control module 30.Particularly, household electrical appliance can comprise and may leak and cause dangerous household electrical appliances, such as, insulating pot, soy bean milk making machine, fruit juice mixer, electromagnetic oven, Garment Steamer Machine, foot basin, the leak water detdction circuit 100 of the utility model embodiment may be used for detecting, such as, the leaking of soy bean milk making machine, the infiltration of fruit juice mixer motor shaft, the spilling water of electromagnetic oven, foot basin leak.
Wherein, detection module 10 comprises detecting electrode 101, detecting electrode 101 is arranged at the outside of household electrical appliance, for detecting leaking and output feedback signal of household electrical appliance, detecting electrode 101 can be arranged at household electrical appliance and easily to leak or leak the place of easy process, such as, on the base of insulating pot, when household electrical appliance leak and do not leak, detecting electrode 101 output feedback signal is different, and the resistance such as exported, voltage or electric current are different.
Acquisition module 20 is connected with detection module 10 and control module 30.Acquisition module 20 exports leak water detdction signal according to the feedback signal of detection module 10, control module 30 is connected with the controller 300 of acquisition module 20 and household electrical appliance, leak water detdction signal is sent to control module 30 by acquisition module 20, control module 30 pairs of leak water detdction signals calculate, judge water leakage situation, such as, when control module 30 judges that leak water detdction signal is greater than predetermined threshold value, namely judge that insulating pot 1000 leaks.And then, if according to leak water detdction signal, control module 30 judges that household electrical appliance leak, then export water leakage to controller 300, and then controller 300 can do and processes further, such as, controller 300 controls household electrical appliance and quits work, and carries out alarm simultaneously, thus household electrical appliance can be avoided because leaking to jeopardize user security and property loss.
Particularly, in an embodiment of the present utility model, the detecting electrode 101 of detection module 10 can comprise the form of multiple existence, such as, can for the one printed electrode and in electrode probe, to print electrode or electrode probe is positioned over household electrical appliance and easily leaks or leak the position easily flowed through.
Be illustrated in figure 2 the schematic diagram of the leak water detdction circuit according to a specific embodiment of the present utility model.Figure 3 shows that the schematic diagram according to the motor probe in the leak water detdction circuit of another embodiment of the present utility model.Such as shown in Fig. 2 and Fig. 3, to print electrode or electrode probe is two.
