As shown in fig. 9, when the flushing end 404 is a straight pipe, the first outlet group 405a, the second outlet group 405b, and the third outlet group 405c are sequentially disposed at the bottom of the flushing end 404, the axes of the water outlets in the first outlet group 405a and the third outlet group 405c are all acute angles along the included angle between the pipe walls of the flushing end 404, the axis of the water outlet in the second outlet group 405b is perpendicular to the pipe wall of the flushing end 404, and the axes of the water outlets in the first outlet group 405a, the second outlet group 405b, and the third outlet group 405c have the same included angle with the vertical plane.

Under the structure, the heights of the first water outlet hole group 405a, the second water outlet hole group 405b and the third water outlet hole group 405c are equal, so that the included angle between the axis of the water outlet hole in the first water outlet hole group 405a and the pipe wall of the washing end 404 is larger than the included angle between the axis of the water outlet hole in the third water outlet hole group 405c and the pipe wall of the washing end 404.

In the present invention, when the flushing end 404 is provided, the inner diameter of the flushing end 404 at the positions of the first water outlet hole group 405a, the second water outlet hole group 405b, and the third water outlet hole group 405c can be made smaller than the inner diameter of the remaining parts, so as to appropriately increase the water outlet pressure of the first water outlet hole group 405a, the second water outlet hole group 405b, and the third water outlet hole group 405c, thereby improving the cleaning effect.

In the present invention, the turret 3 is used, on the one hand, for carrying dishes and, on the other hand, for rotating the dishes about the axis of the washing chamber 2. Specifically, as shown in fig. 3 to 6, the rotating frame 3 includes a fixed frame 301 and a movable frame 302, wherein the fixed frame 301 is fixedly installed in the cleaning chamber 2, the movable frame 302 is rotatably connected in the fixed frame 301, the bottom of the movable frame 302 is suspended in the fixed frame 301, and a driving assembly 5 for driving the movable frame 302 to rotate is disposed in the housing 1. The movable frame 302 is rotated on the fixed frame 301 by the driving assembly 5, so that the dishes loaded on the movable frame 302 are all washed through the washing port 404.

In the present invention, as shown in fig. 3 to 5, the driving assembly 5 includes a plurality of plate bodies 501 disposed at the bottom of the movable frame 302, and a driving water pipe 502 disposed in the casing 1 and jetting water to the plate surfaces of the plate bodies 501, the driving water pipe 502 is connected to a tap water pipe; the plurality of plate bodies 501 are distributed in a circular shape at the bottom of the movable frame 302, and the water outlet of the driving water pipe 502 faces the plate surface direction of the plate body 501. Through the arrangement mode, the movable frame 302 can be driven to rotate by the impact pressure of tap water, so that energy is saved.

In addition, in order to prevent tap water from splashing upward into the dishes when impacting the plate 501, a partition 303 may be connected inside the movable frame 302 and above the plate 501, and water leakage holes 304 may be distributed on the partition 303.

In the present invention, the driving water pipe 502 may be connected to the tap water pipe through a pressure reducing valve in order to prevent the impact of the tap water on the plate body 501 from being excessive.

In addition, since the dishwasher requires addition of washing powder, it is common to provide a powder storage box in the dishwasher and to deliver the washing powder to the surface of the dishes by providing a separate water channel. In the present invention, the water inlet pipe 401 divides water flow into two streams, one is a normal wash pipe 402 and the other is a wash pipe 406 for supplying washing powder to dishes at the initial stage of washing, and the wash pipe 402 and the wash pipe 406 are connected by an electromagnetic three-way valve 407, and a powder storage box provided in the dishwasher is connected to the wash pipe 406. When washing dishes, firstly, the control system controls the electromagnetic three-way valve 407 to open the washing liquid pipe 406 to enable tap water to enter the washing liquid pipe 406, the powder storage box also sends washing powder to the surfaces of the dishes along with the water flow in the washing liquid pipe 406, and after the rotating frame 3 rotates to a set number of turns, the control system controls the electromagnetic three-way valve 407 to disconnect the washing liquid pipe 406 and connect the flushing pipe 402 to enable the tap water to enter the flushing end 404 from the flushing pipe 402 to flush the dishes. It should be noted that the end of the wash pipe 406 is also provided with a flush end 404 similar to the end connected to the flush pipe 402, i.e. the flush end 404 is provided with two, one connected to the end of the flush pipe 402 and the other connected to the end of the wash pipe 406. And the flushing port 404 is connected to the flushing pipe 402 and the washing liquid pipe 406 using a rotary valve, respectively, so that the flushing port 404 is rotatable to have a bypass effect when the movable frame 302 is put into the fixed frame 301.

It should be noted that, a heating mechanism is further arranged in the dishwasher to heat the tap water entering the cleaning cavity 2, so as to improve the cleaning effect. The application of this technology is common knowledge in the art and will not be described in detail in this specification.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept.
