When the flow sensor 500 does not feed back a flow signal to the control device 400, it indicates that water does not enter the grinding chamber 140, at this time, the control device 400 determines not to start the motor 130, so as to avoid the situations that the grinding mechanism 120 is dry-ground in a water-free state, which causes high noise, and the residue is easy to block the drain pipe. When the flow sensor 500 feeds back a flow signal to the control device 400, it indicates that water enters the grinding chamber 140, at this time, the control device 400 determines to start the motor 130, and the grinding mechanism 120 crushes the kitchen waste with the water in the state that the grinding chamber is in the water inlet state, so that the kitchen waste is mixed with the water into slurry, and the slurry is discharged from the drain pipe.

In order to ensure that the actual inflow rate in the grinding chamber 140 is consistent with the preset inflow rate, the flow sensor 500 feeds back an actual inflow rate signal to the control device 400 in real time after the motor 130 is started, the control device 400 compares the flow signal fed back by the flow sensor 500 with a preset inflow rate value, and corrects the opening of the inflow control valve 200 in real time according to the comparison value of the flow signal and the preset inflow rate value, so that the actual inflow rate is consistent with the preset inflow rate value, and the inflow requirement during grinding is better met.

In order to make the motor 130 drive the grinding mechanism 120 to operate under the condition that the grinding chamber 140 has water, the control method further comprises the following steps: before the motor 130 is started, the control device 400 determines whether to start the motor 130 according to whether the flow rate signal is fed back by the water flow sensor 500. If the flow sensor 500 does not feed back a flow signal to the control device 400, the control device 400 determines not to start the motor 130; when the flow rate signal is fed back from the water flow sensor 500 to the control unit 400, the control unit determines to start the motor 130.

The control device 400 writes in inflow preset values corresponding to the current ranges, and in order to ensure that the actual inflow in the grinding chamber 140 is consistent with the inflow preset values, the control method further comprises the following steps: the water flow sensor 500 feeds back an actual inflow water flow signal to the control device 400 in real time after the motor 130 is started, and the control device 400 commands the inflow water control valve 200 to correct the opening degree according to a comparison value between the flow signal fed back by the water flow sensor 500 and an inflow water flow preset value.

In this embodiment, the current signal values fed back by the current detecting member 300 are divided into three current ranges, and accordingly, the inflow water flow rate preset values of the inflow water control valve 200 are also divided into three flow rate states. If the current signal value fed back by the current detector 300 belongs to the first current range Δ I₁The control device 400 commands the water intake control valve 200 to adjust the water intake flow rate to the first flow rate Q₁. If the current signal value fed back by the current detection element 300 belongs to the second current range delta I₂The control device 400 commands the water intake control valve 200 to adjust the water intake flow rate to the second flow rate Q₂. If the current detecting element 300 feeds back electricityThe value of the flow signal falling within the third current range Δ I₃The control device 400 commands the intake control valve 200 to adjust the intake water flow rate to the third flow rate Q₃And commands the intake control valves 200 to be closed after a time interval deltat.

When the current signal value fed back by the current detection element 300 belongs to the second current range delta I₂When the water inflow rate is adjusted to be smaller, the control device 400 may command the second indicator lamp 620 to flash, which indicates that the kitchen waste in the grinding chamber 140 is less or softer. When the current signal value fed back by the current detection element 300 belongs to the third current range delta I₃In this case, it is indicated that the grinding chamber 140 has substantially no kitchen waste, and the inflow rate can be further reduced. Specifically, when the weight of the kitchen waste in the grinding chamber 140 is not less than 350g, it is determined that the amount of the kitchen waste is large. When the weight of the kitchen waste in the grinding chamber 140 is less than 350g, it is determined that the kitchen waste is less.
