Description

Technical Field

[0001] This disclosure relates to the field of dishwasher control technology, and in particular to a dishwasher, a dishwasher noise reduction method, and an electronic device. Background Technology

[0002] As dishwashers become increasingly popular, the problem of their operating noise has become more and more prominent. How to effectively solve the noise problem during dishwasher operation has become a key point in dishwasher optimization.

[0003] In related technologies, noise reduction is often achieved by physically blocking the sound propagation path of the dishwasher by placing sound insulation cotton outside the cavity. However, this method can only weaken the propagation of noise and cannot suppress the generation of noise at the source. Moreover, adding extra sound insulation cotton not only increases the production cost of the dishwasher, but also occupies more internal structural space, compresses the effective volume of the washing cavity, and limits the overall design, resulting in limited noise reduction effect, poor user experience, and high product cost. Summary of the Invention

[0004] This disclosure provides a dishwasher, a dishwasher noise reduction method, and an electronic device to at least solve the problems in related technologies where noise generation cannot be suppressed at its source, and where the addition of sound-absorbing cotton compresses the effective volume of the washing chamber, limiting the overall design, resulting in limited noise reduction effect, poor user experience, and high product cost.

While the cleaning chamber is performing the cleaning operation, the system acquires the current angle information of the cleaning chamber in the preset coordinate system, measured by an angle detection device. Based on the initial and current angle information, the system determines the horizontal angle offset of the cleaning chamber in the preset horizontal axis direction and the vertical angle offset in the preset vertical axis direction. The system can acquire the angle offset of the dishwasher's cleaning chamber in real time during the cleaning process, thereby determining the degree of tilt of the cleaning chamber based on the angle offset. If the absolute value of either the horizontal or vertical angle offset is greater than a preset offset threshold, the system adjusts the operating power of a preset balancing device based on the horizontal and vertical angle offsets to ensure that the absolute values ​​of both the horizontal and vertical angle offsets are less than the preset offset thresholds. By adjusting the operating power of the balancing device when the angle offset exceeds the preset threshold, the system can keep the cleaning chamber level, thereby avoiding noise caused by uneven placement of the cleaning chamber during the cleaning process. This suppresses noise generation at its source, improving noise reduction and user experience.

[0026] In step S303, when a cleaning operation is performed in the cleaning chamber, the current angle information of the cleaning chamber in the preset coordinate system is obtained by the angle detection device. In a specific embodiment, the current angle information can be the angle information corresponding to the cleaning operation performed by the cleaning chamber.

[0027] In step S305, based on the initial angle information and the current angle information, the horizontal angle offset of the cleaning chamber in the preset horizontal axis direction and the vertical angle offset of the cleaning chamber in the preset vertical axis direction are determined. In a specific embodiment, the horizontal axis angle offset can be the angle offset of the cleaning chamber in the preset horizontal axis direction, and the vertical axis angle offset can be the angle offset of the cleaning chamber in the preset vertical axis direction. Specifically, the horizontal axis angle offset can be the difference between the horizontal axis angle information in the current angle information and the horizontal axis angle information in the initial angle information, and the vertical axis angle offset can be the difference between the vertical axis angle information in the current angle information and the vertical axis angle information in the initial angle information. Optionally, the initial angle information can be (10°, 8°), the angle information corresponding to the preset horizontal axis direction in the initial angle information can be 10°, the angle information corresponding to the preset vertical axis direction in the initial angle information can be 8°, the current angle information can be (13°, 7°), the angle information corresponding to the preset horizontal axis direction in the current angle information can be 13°, the angle information corresponding to the preset vertical axis direction in the current angle information can be 7°, and correspondingly, the horizontal axis angle offset can be 3°, and the vertical axis angle offset can be -1°.
