When cleaning the tableware, the control partition is returned to the first position so that the upper and lower chambers inside the box-type dishwasher are connected. When entering the half-chamber cleaning mode, the time for the partition motor to run to generate the blocking current is used as the time timing of the entire forward process. According to the comparison result of the partition forward time and the preset time range, it is quickly identified that the user has encountered obstacles in the forward movement of the partition due to the wrong placement of tableware, resulting in the problem of insufficient sealing of the upper and lower chambers. In the process of controlling the movement of the lower position switch of the water diversion valve, it is detected whether there is a single failure of the upper and lower micro switches according to the change of the electrical signal parameters, and the high and low levels are calculated by the electrical signal of the switch that has not failed, and the position closure of the water diversion valve at the failed end is accurately controlled in time.

[0080] The cleaning control method of the box-type dishwasher of this embodiment determines whether an abnormality occurs in the partition motor during the retraction process of the partition through the retreat state parameters, thereby ensuring precise control of the subsequent half-cavity cleaning mode and improving the user experience.

[0081] In one feasible solution, Figure 4 As shown, the forward state parameters include the partition forward time, the second stall current value and the second stall time, and step S14 specifically includes:

[0082] S141, detecting whether the partition board advancing time is greater than a third time threshold. If yes, executing step S142, if no, executing step S143.

[0084] S143: When it is detected that the second stall current value is greater than the second current threshold, continue to detect whether the second stall time is greater than the fourth time threshold. If so, execute steps S144 and S145.

[0085] S144. When it is detected that the partition advance time is greater than the fifth time threshold, it is determined that the advance state parameter meets the second preset condition.

[0086] S145. When it is detected that the partition advance time is not greater than the fifth time threshold, it is determined that the partition motor is blocked by the tableware, causing abnormal advance.

[0087] The cleaning control method of the box-type dishwasher of this embodiment determines whether the partition motor has failed or is blocked by tableware during the process of retreating and advancing through the forward state parameters, thereby ensuring the precise control of the subsequent half-cavity cleaning mode and improving the user experience.

[0088] In one feasible solution, Figure 5 As shown, the electrical signal parameters include lower signal parameters and upper signal parameters, the lower signal parameters include the first strong current accumulated time and the first level signal, the upper signal parameters include the second strong current accumulated time, the water diversion valve time action and the second level signal, step S16 specifically includes:

[0095] S166: After accumulating the time duration of the first timing duration, re-execute step S163.

[0096] S167, after accumulating the time for which the second timing duration during which the second level signal is at a high level continues, re-execute step S163.

[0097] When entering the half-cavity cleaning mode, the lower-layer side spraying operation requires the lower-layer position switch of the water-dividing valve to be in place, the water-dividing valve is powered on with strong electricity and timing is performed to obtain the first strong electricity cumulative time, the lower-layer signal parameters of the water-dividing valve are first detected, and when the first strong electricity cumulative time is not greater than the first cycle threshold, there is no abnormality in the lower-layer signal parameters of the water-dividing valve, and the lower-layer side spraying position is determined to be in place according to the first timing duration corresponding to the low level of the first level signal. When the first strong electricity cumulative time is greater than the first cycle threshold, there is an abnormality in the lower-layer signal parameters of the water-dividing valve, the water-dividing valve is powered on with strong electricity and the timing is performed again to obtain the second strong electricity cumulative time, and then the upper-layer signal parameters of the water-dividing valve are detected, and the lower-layer side spraying position is determined to be in place according to the water-dividing valve time action and the second level signal. It should be noted that the control time threshold (T) can also be determined by the first timing duration (marked as TC), the second timing duration (marked as TB) and the second cycle threshold (marked as T3), for example, T = (TC + ​​TB) / 2 + T3.

[0098] In this method, when a single micro switch of the upper and lower water diverter valve fails, the high and low level time and cycle are calculated by the micro switch that has not failed, so as to accurately control the closing position of the water diverter valve at the failed end in terms of time.

[0099] In the present embodiment, a cleaning control method for a box-type dishwasher is provided, in which cavity isolation is achieved by driving a partition motor, and a switch assembly of a water diverter valve on a spray device is driven to isolate the cleaning water path. The partition motor and the water diverter valve are driven separately according to precise control logic to work together, thereby automatically and accurately achieving chamber cleaning and improving user experience.

[0123] When entering the half-cavity cleaning mode, the lower-layer side spraying operation requires the lower-layer position switch of the water-dividing valve to be in place, the water-dividing valve is powered on with strong electricity and timing is performed to obtain the first strong electricity cumulative time, the lower-layer signal parameters of the water-dividing valve are first detected, and when the first strong electricity cumulative time is not greater than the first cycle threshold, there is no abnormality in the lower-layer signal parameters of the water-dividing valve, and the lower-layer side spraying position is determined to be in place according to the first timing duration corresponding to the low level of the first level signal. When the first strong electricity cumulative time is greater than the first cycle threshold, there is an abnormality in the lower-layer signal parameters of the water-dividing valve, the water-dividing valve is powered on with strong electricity and the timing is performed again to obtain the second strong electricity cumulative time, and then the upper-layer signal parameters of the water-dividing valve are detected, and the lower-layer side spraying position is determined to be in place according to the water-dividing valve time action and the second level signal. It should be noted that the control time threshold (T) can also be determined by the first timing duration (marked as TC), the second timing duration (marked as TB) and the second cycle threshold (marked as T3), for example, T = (TC + ​​TB) / 2 + T3.

[0124] In this method, when a single micro switch of the upper and lower water diverter valve fails, the high and low level time and cycle are calculated by the micro switch that has not failed, so as to accurately control the closing position of the water diverter valve at the failed end in terms of time.

[0125] In the present embodiment, a cleaning control device for a box-type dishwasher is provided, which realizes cavity isolation by driving a partition motor, and realizes isolation of the cleaning water path by driving a switch assembly of a water diverter valve on a spray device. The partition motor and the water diverter valve are driven separately according to precise control logic to work together, thereby automatically and accurately realizing cavity cleaning and improving user experience.
