The washing control method of the dishwasher specifically comprises the following steps:

and step S101, starting the dishwasher to clean the tableware.

In the embodiment, after the dish washing machine receives a tableware washing instruction issued by a user, the controller detects whether the door body is in a closed state; if yes, go to step S102; if not, the operation is stopped and the dishwasher is controlled to enter a standby state.

And S102, detecting the tableware, so as to obtain the number N of the tableware on the clamping seat, wherein the height of the tableware exceeds the height of the supporting rod.

In this embodiment, the infrared transmitter on each card holder is simultaneously started to transmit infrared rays to the infrared receiver;

the infrared receiver does not receive the infrared rays emitted by the infrared emitter, and the fact that the height of the tableware on the current clamping seat exceeds the height of the supporting rod is determined;

and counting the number of the infrared detection assemblies corresponding to the tableware exceeding the height of the supporting rod, so as to obtain the number N of the tableware exceeding the height of the supporting rod on the clamping seat.

In this embodiment, the corresponding infrared transmitter on each card seat is simultaneously started to transmit infrared rays to the infrared receiver, and whether the infrared receiver receives the infrared rays transmitted by the infrared transmitter is judged; if so, judging that the height of the tableware on the current clamping seat does not exceed the height of the supporting rod; if not, the height of the tableware on the current clamping seat is judged to exceed the height of the supporting rod. And then counting the number of the infrared detection assemblies corresponding to the tableware exceeding the height of the supporting rod, so as to obtain the number N of the tableware exceeding the height of the supporting rod on the clamping seat, wherein the number N is the sum of the infrared detection assemblies corresponding to each group of tableware exceeding the height of the supporting rod.

And S103, judging whether the number N is multiple, controlling the work of a booster pump according to the judgment result to adjust the spraying water pressure of the spraying arm, and/or controlling the work of a water inlet valve to adjust the spraying time length of the spraying arm.

In this embodiment, it is determined whether the number N is plural;

if yes, comparing the quantity N with the quantity Q, and if the quantity N is multiple, indicating that the cleaning area of the tableware is large, and correspondingly increasing the spraying water pressure and the spraying time length so as to meet the requirement of the tableware cleaning effect;

if not, adjusting the power of the booster pump to be first preset power, and simultaneously controlling the work of the water inlet valve to adjust the spraying time length of the spraying arm to be first preset time length.

In this embodiment, after comparing the quantity N with the quantity Q, according to a determination result, controlling the operation of the booster pump to adjust the spray water pressure of the spray arm, and/or controlling the operation of the water inlet valve to adjust the spray duration of the spray arm, in this embodiment, it is preferable to divide the sum N of the infrared detection assemblies corresponding to each set of tableware exceeding the height of the trunnion into three levels for comparison, that is, into three levels of N ≦ 0.3Q, 0.3Q ≦ 0.7Q, and 0.7Q ≦ N ≦ Q, but not limited to the above three levels, and it is also possible to divide the three levels into other more suitable levels according to actual requirements, and the step of comparing the quantity N with the quantity Q specifically includes:

comparing the number N with the number Q;

if N is less than or equal to 0.3Q, adjusting the power of the booster pump to a second preset power, and simultaneously controlling the work of the water inlet valve to adjust the spraying time length of the spray arm to a second preset time length;

if N is greater than 0.3Q and less than or equal to 0.7Q, adjusting the power of the booster pump to a third preset power, and simultaneously controlling the work of the water inlet valve to adjust the spraying time length of the spraying arm to a third preset time length;

and if N is greater than 0.7Q and less than or equal to Q, adjusting the power of the booster pump to a fourth preset power, and simultaneously controlling the work of the water inlet valve to adjust the spraying time length of the spraying arm to a fourth preset time length.

In this embodiment, in order to automatically match the dishwasher with a more suitable washing mode according to the height of the dishes, the first preset power may be less than or equal to the second preset power, and the third preset power is greater than the second preset power and less than the fourth preset power;

the first preset time length is less than or equal to the second preset time length, and meanwhile, the third preset time length is greater than the second preset time length and less than the fourth preset time length. More preferably, the first preset power is preset to 60W, the second preset power is preset to 60W, the third preset power is preset to 70W, the fourth preset power is preset to 80W, similarly, the first preset time period is preset to 30min, the second preset time period is preset to 30min, the third preset time period is preset to 45min, and the fourth preset time period is preset to 60 min.

And step S104, the dishwasher carries out cleaning work according to the adjusted spraying time and/or spraying water pressure.

Step S105, the cleaning work of the tableware is completed.

In this embodiment, after the controller performs the cleaning operation according to the adjusted spraying duration and/or spraying water pressure, until the cleaning operation is completed, the dishwasher stops operating and sends a prompt to the user to complete the cleaning operation of the tableware.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
