In this embodiment, by detecting the float switch signal and the metal probe signal at the same time, the double logic determines whether water overflows. Therefore, the reliability and accuracy of detection are improved, and detection failure or misjudgment is prevented.
The float switch is controlled to disconnect the drain solenoid valve of the washing apparatus and to be connected to the first overflow detecting circuit before a float switch signal generated by the overflow is detected by the first overflow detecting circuit. When the drainage electromagnetic valve is powered off, water cannot enter, and the overflow is prevented from being serious. And a first overflow detection circuit is connected to start double logic judgment, so that the reliability of overflow detection is improved.
In the above embodiment, the control unit may be configured to control to turn on the drain pump of the washing apparatus, and specifically, may send a turn-on command to the drain pump control circuit to trigger the turn-on of the drain pump of the washing apparatus. And then controlling other loads of the cleaning equipment to stop running. The device can prevent other loads from being electrified and passing water, reduce the risk of overcurrent and ensure the safety of the device.
After at least one of the float switch signal and the metal probe signal is detected and the water overflow is determined to occur, the water overflow fault can be displayed on a display interface; and/or, trigger an alarm. Thereby reminding the user of the risk of water overflow and maintaining in time.
Fig. 4 is a flowchart of a control method of the overflow detecting device according to the embodiment of the present invention, as shown in fig. 4, the flow is as follows: after the whole machine is electrified, the MCU starts to receive the feedback signal and judges whether the received signal is a float switch signal or a metal probe signal, the float switch signal can be used as a first detection signal, and the metal probe signal can be used as a second detection signal. The MCU immediately sends a control instruction as long as receiving at least one feedback signal (for example, two signals are all received in fig. 4), and the drainage pump control circuit works to control the drainage pump to be started to drain the water in the dishwasher, so that more water is prevented from overflowing. Meanwhile, the MCU sends an instruction to close other loads to operate, and the display interface displays an overflow fault and reminds a user to contact after-sale maintenance. After-sales maintenance solves the problem of water overflow, and the process is finished.
