In order to make the grinding mechanism 120 start to work under the premise that water exists in the grinding chamber 140, the kitchen waste treatment system of the embodiment further includes a water flow sensor 500 for knowing the water inflow condition in the grinding chamber 140, where the water flow sensor 500 is disposed downstream of the water inflow control valve 200 and is connected to the control device 400 by a signal, and the control device 400 determines whether to start the motor 130 according to whether the water flow sensor 500 feeds back the flow signal. When the water flow sensor 500 does not feed back the flow signal to the control device 400, it indicates that there is no water in the grinding chamber 140, and at this time, the control device 400 determines that the motor 130 is not started, so as to avoid the situations of loud noise, easy blockage of the drain pipe due to residues, and the like, caused by dry grinding of the grinding mechanism 120 in the anhydrous state.

The first embodiment of the present invention further provides a control method applied to the kitchen waste treatment system, where the control device 400 determines, after the motor 130 is started, a current range to which the motor belongs according to a current signal value fed back by the current detecting element 300, and then instructs the water inlet control valve 200 to adjust the opening to a corresponding water inlet flow according to the current range, if the current range is higher, the water inlet flow is increased, and if the current range is lower, the water inlet flow is decreased.
In order to make the motor 130 drive the grinding mechanism 120 to operate under the condition that water exists in the grinding chamber 140, the control method further includes the steps of: the control device 400 determines whether to start the motor 130 according to whether the water flow sensor 500 feeds back the flow signal before the motor 130 starts. If the water flow sensor 500 does not feed back the flow signal to the control device 400, the control device 400 determines that the motor 130 is not started; if the water flow sensor 500 feeds back a flow signal to the control device 400, the control device determines to activate the motor 130.
The control device 400 writes in preset inflow water flow values corresponding to the current ranges respectively, and in order to ensure that the actual inflow water flow in the grinding chamber 140 is consistent with the preset inflow water flow value, the control method further comprises the steps of: the water flow sensor 500 feeds back the actual inflow flow signal to the control device 400 in real time after the motor 130 is started, and the control device 400 commands the inflow control valve 200 to correct the opening according to the comparison value of the inflow flow preset value and the inflow flow signal fed back by the water flow sensor 500.
In this embodiment, the current signal value fed back by the current detecting element 300 is divided into three current ranges, and accordingly, the preset value of the water inlet flow of the water inlet control valve 200 is also divided into three flow states. If the current signal value fed back by the current detecting element 300 belongs to the first current range ΔI 1 The control device 400 instructs the water inlet control valve 200 to adjust the water inlet flow rate to the first flow rate Q 1 . If the current signal value fed back by the current detecting element 300 belongs to the second current range Δi 2 The control means 400 instructs the water inlet control valve 200 to adjust the water inlet flow rate to the second flow rate Q 2 . If the current signal value fed back by the current detecting element 300 belongs to the third current range Δi 3 The control means 400 instructs the inflow control valve 200 to adjust the inflow amount to the third flow rate Q 3 And commands the inlet control valve 200 to close after a time interval deltat. ΔI 1 ＞ΔI 2 ＞ΔI 3 ，Q 1 ＞Q 2 ＞Q 3 The time interval delta T is 1 min-5 min.

When the current is detected300 the current signal value fed back belongs to the second current range delta I 2 When the kitchen waste in the grinding chamber 140 is less or softer, the water inflow rate can be adjusted to be smaller, and the control device 400 can command the second indicator 620 to flash. When the current signal value fed back by the current detecting member 300 falls within the third current range ΔI 3 When the grinding chamber 140 is provided with no kitchen waste, the water inflow 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 kitchen waste is more. 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.
