Describe the leak water detdction circuit for household electrical appliance according to embodiments of the present invention 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 embodiment of the present invention is illustrated.
Fig. 1 is the block diagram of the leak water detdction circuit for household electrical appliance according to an embodiment of the invention. As it is shown in figure 1, the leak water detdction circuit 100 for household electrical appliance of the embodiment of the present invention includes detection module 10 and acquisition module 20. Specifically, household electrical appliance can include it may happen that 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 embodiment of the present invention may be used for detection, 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 is for detecting leaking and output feedback signal of household electrical appliance, detection module 10 can be arranged at household electrical appliance and easily leak or leak the place of easy process, when household electrical appliance leak and do not leak, detection module 10 output feedback signal is different, for instance the resistance of output, voltage or electric current are different.
Acquisition module 20 is connected with the controller 300 of detection module 10 and household electrical appliance respectively. Acquisition module 20 exports leak water detdction signal according to the feedback signal of detection module 10, and sends leak water detdction signal to controller 300 so that controller 300 judges water leakage situation. And then, if according to leak water detdction signal, controller 300 judges that household electrical appliance leak, then can do and process further, such as, controller 300 controls household electrical appliance and quits work, carry out alarm, such that it is able to avoid household electrical appliance to jeopardize user security and property loss because leaking simultaneously.
Specifically, in one embodiment of the invention, detection module 10 can include the form of multiple existence, for instance, detection module includes printing electrode and one in electrode probe, prints electrode or electrode probe is positioned over household electrical appliance and easily leaks or leak the position easily flowed through.
It is illustrated in figure 2 the schematic diagram of the leak water detdction circuit of a specific embodiment according to the present invention. The schematic diagram of the motor probe that Fig. 3 show in leak water detdction circuit according to another embodiment of the invention.
