Problems solved by technology

[0002] In the prior art, the dishwasher uses a spray arm to wash the tableware, and the spray water flow is required to be strong enough to clean the tableware to ensure the cleaning effect, and the spray water flow comes from the driving mode of the washing pump , due to the special structure of the spray arm, it is required that the washing pump can only rotate in a specified direction to obtain the corresponding spraying force; the required force, and thus the cleaning effect cannot be guaranteed
[0003] However, the washing pumps of existing dishwashers usually use synchronous motors. Since the synchronous motors cannot ensure that the washing pumps run in one direction in the specified direction when the synchronous motors are turned on, it is urgent to design a deviation correction method that can detect the washing pumps in time. Rotate it in reverse and correct it, so as to ensure the strength of the water flow sprayed by the spray arm, and improve the washing efficiency and washing effect of the tableware

Embodiment 1

[0046] The embodiment of the present invention provides a dishwasher, including a housing, a liner disposed within the housing, a washing chamber in which a tableware is provided in the washing chamber, and a tableware shelf is used for Tableware, the spray arm is driven by a washing pump disposed between the housing and the liner, and the spray arm is discharged to rinse the tableware in the washing chamber.

[0047]Since the motor of the existing washing pump adopts a synchronous motor, the motor cannot guarantee the unidirectional operation in the designated direction, so in order to avoid the influence of the reverse rotation of the washing pump, the dishwasher also includes and washing The control system of the bowl machine is electrically connected audio acquisition module, the data processing module, and the analysis module, the audio acquisition module acquires the audio signal in the washing chamber of the dishwasher, and the data processing module is used to perform the ...

Embodiment 2

[0051] like figure 1 As shown, the embodiment of the present invention also provides a correction method of a dishwasher, and is applied to the dishwasher in the first embodiment, and when the washing pump in the dishwasher occurs in reverse rotation, the steering of the washing pump is carried out. adjust. The correcting method of the dishwasher includes the following steps:

[0052] S1, get the audio signal in the washing chamber of the dishwasher.

[0053] The audio signal in the dishwasher is acquired by the audio acquisition module. The audio acquisition module is collected is a water flow impact liner or the audio signal of the spray arm ejected in the washing chamber.

[0054] Since the forward rotation and reverse rotation of the washing pump are different, the flow of the flow of the spray arm sprayed is different. When the washing pump is rotated, the flow of the spray arm is large, the audio signal in the washing chamber Larger; when the washing pump is rotated in rever...

Embodiment 3

[0064] like figure 2 As shown, the embodiment of the present invention further provides a correction method of a dishwasher, and is a further improvement made on the basis of the second embodiment, and may be applied to the dishwasher in Example No. 1, the cleavage method of the dishwasher includes The following steps:

[0065] S11, get the audio signal in the washing chamber of the dishwasher.

[0066] S21, the acquired audio signal is compared to the preset audio signal to obtain a comparison result.

[0067] S31, if the audio signal is less than the preset audio signal, the washing pump is in the reverse rotation state, and the dishwasher restarts the washing pump.

[0068] If the audio signal is not less than the preset audio signal, the washing pump is in a forward rotation, and the dishwasher continues to work. Through the above judgment, it is convenient to determine the steering of the washing pump.

[0069] The dishwasher adjusts the steering of the washing pump by restar...

Abstract

The invention relates to the technical field of dish-washing machines, and discloses a deviation rectifying method of a dish-washing machine and the dish-washing machine. The deviation rectifying method of the dish-washing machine comprises the steps of S1, acquiring an audio signal in a washing cavity of the dish-washing machine; S2, comparing the acquired audio signal with a preset audio signal to obtain a comparison result; and S3, according to the comparison result, judging the rotating direction of a washing pump of the dish-washing machine, and when it is detected that the washing pump is in a reverse rotating state, enabling the dish-washing machine to adjust the rotating direction of the washing pump so as to enable the washing pump of the dish-washing machine to drive a spraying arm in a forward rotating mode, thereby improving the washing efficiency and the washing effect of the dish-washing machine. Compared with a mode of directly acquiring rotation parameters of the washing pump, the method is simpler and more convenient.

Description

Technical field [0001] The present invention relates to the technical field of dishwasher, and more particularly to a diagrading method of dishwasher and a dishwasher. Background technique [0002] In the prior art, the dishwasher is washed in the manner in the manner, requiring the sprayed water flow to be large enough to wash the cutting cutlery to ensure the cleaning effect, while the spray water flow is derived from the driving method of the washing pump. Due to the special structure of the spray arm, the detergent pump can only be rotated in the designated direction to obtain the corresponding spray force; if the washing pump is rotated, the water flow of the spray arm sprayed is small, and cannot be reached. The required strength, thereby causing the cleaning effect. [0003] The washing pump of the existing dishwasher usually uses a synchronous motor. Since the synchronous motor is not guaranteed to perform one-way operation in the designated direction, there is an urgent ...
