Description

Technical Field

[0001] The present application relates to the field of automatic cleaning technology, and in particular to a full-area spray assembly and a cleaning device. Background Art

[0002] In today's era, with the rapid development of science and technology and the continuous improvement of people's living standards, automatic cleaning devices in daily life are showing a significant trend of increasing. In many practical application scenarios, the square structure can better arrange the space, and the manufacturing, assembly and installation are relatively simple, and it is also convenient for users to operate. Therefore, many cleaning devices adopt a square structure, such as dishwashers. The inner cavity of existing dishwashers currently adopts a square cavity, that is, the projection in the height direction is a rectangle, and other designs are also based on this.

[0003] However, for dishwashers that use the principle of high-pressure water flow generated by rotating spray arms for cleaning, the existing rotating spray arm water flow drives the spray arm to rotate, and its spray trajectory is circular. This circular spray range will make the four corners of the square inner cavity and other areas become cleaning dead corners, which cannot be fully covered by the water flow, resulting in poor cleaning effect. In order to improve this problem, industry personnel have tried a variety of spray arm designs, such as designing the spray arm as a special-shaped structure, or adding multiple auxiliary spray arms. However, the final spray trajectory of these improvement schemes is the superposition of circular trajectories, which can only improve the spray trajectory to a certain extent and cannot overcome the problem of dead corners around. Although in theory if there are enough spray arms, the spray trajectory can be very close to a square, too many spray arms will greatly increase the cost, assembly difficulty and failure frequency. Therefore, it is necessary to find a better full-area spray solution suitable for square cavities. Summary of the invention
