Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a spray structure for a cleaning machine and the cleaning machine itself. Background Technology

[0002] For countertop and cabinet dishwashers, due to their large washing space, they are generally designed with three spray arms—top, middle, and bottom—to achieve better washing results. The middle and top spray arms are supplied with water through internal water pipes extending upwards close to the inner wall of the washing chamber. During operation, the washing pump delivers water through the pipes to the top, middle, and bottom spray arms. The water sprays out from these arms, rinsing the dishes before falling back into the water cup at the bottom of the dishwasher. The washing pump then delivers the fallen water back to the top, middle, and bottom spray arms, completing one cycle. For details, please refer to Chinese patent application number CN202321315257.7, "Water Flow System for a Washing Machine and Washing Machine".

[0003] However, the spray arm usually moves in a circular motion, and the water coverage in its central area is usually less, which often results in a cleaning dead zone. When users place tableware in this area, it is often not cleaned properly, which is especially noticeable with the top spray arm.

[0004] The existing technologies for addressing this problem include:

[0005] First, a localized sprinkler system can be added. However, localized sprinkler systems are expensive, take up a lot of space, and have a significant impact on the lift of the main sprinkler arm when activated.

[0006] Secondly, adjusting the gap between the rack wires can prevent dishes from being placed in the center. However, adjusting the gap between the wires can affect the overall upper limit of the dishwasher's tableware capacity, thus limiting the potential for larger set sizes.

[0007] Third, adding a secondary spray arm can improve the washing coverage. However, the secondary spray arm is usually located in the area of ​​the main spray arm. When there are many dishes, it is also impossible to generate enough water flow to clean the dishes in the four corner areas. Utility Model Content

[0008] The first technical problem to be solved by this utility model is to provide a spray structure for a cleaning machine that is simple in structure and can avoid cleaning dead corners in the central area, in light of the current state of the technology.

[0009] The second technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned spray structure.

[0010] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a spray structure for a cleaning machine, including...

[0011] The internal water pipe includes a main pipe and a first branch pipe and a second branch pipe branching off from the outlet end of the main pipe;

[0012] The central spray arm is connected to the outlet end of the first branch pipe; and

[0013] The top spray arm is connected to the outlet end of the second branch pipe and is located directly above the middle spray arm.

[0014] The first branch pipe is characterized by having a fan blade rotatably mounted on its top side, with the fan blade positioned directly opposite the middle of the top spray arm. A spray hole is provided on the top wall of the first branch pipe, and the fan blade is located on the flow path of the water flowing out of the spray hole, so that the fan blade can rotate around its own axis under the action of the water flow and splash the water.

[0015] To facilitate the installation of the fan blades, the top side of the first branch pipe is provided with a mounting base located above the nozzle, and the fan blades are rotatably connected to the mounting base via a rotating shaft.

[0016] To facilitate the processing of the mounting base, the mounting base is in an inverted U-shape.

[0017] To further ensure multi-angle and high coverage cleaning, the mounting base is a flexible component, allowing it to deform under the action of water flow on the fan blades.

[0018] To ensure uniform cleaning, the rotating shaft extends vertically when no external force is applied to the fan blades.

[0019] To ensure consistency in cleaning between the upper and lower layers of the cleaning machine, the middle spray arm and the top spray arm are arranged coaxially.

[0020] Preferably, the main pipeline includes a transverse section extending from front to back along the flow direction of the water flow and a vertical section extending upward from the rear end of the transverse section.

[0021] Preferably, the first branch pipe is connected to the side of the top of the main pipe and extends from back to front.

[0022] Preferably, the second branch pipe is connected to the top of the top of the main pipe and includes a vertical section extending from bottom to top along the flow direction of the water and a transverse section extending forward from the top of the vertical section.

[0023] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a cleaning machine, characterized in that: it applies the above-mentioned spray structure.

[0024] Compared with the prior art, the advantages of this utility model are: by rotating the fan blades on the top side of the first branch pipe and opening spray holes on the top wall of the first branch pipe, since the fan blades are located on the flow path of the water flowing out of the spray holes, they can rotate around their own axis under the action of the water flow and splash the water flow, thereby avoiding the cleaning dead corner in the central area, and the structure is simple.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0029] like Figures 1 to 2 The image shows a preferred embodiment of the cleaning machine with a spray structure according to this utility model. The spray structure includes an inner water pipe 1, a middle spray arm 2, a top spray arm 3, and fan blades 4.

[0030] The inner water pipe 1 is generally E-shaped, including a main pipe 11 and a first branch pipe 12 and a second branch pipe 13 branching from the outlet end of the main pipe 11. Specifically, the main pipe 11 includes a transverse section extending from front to back along the water flow direction and a vertical section extending upward from the rear end of the transverse section. The inlet end of the main pipe 11 is used to connect to the water pump of the cleaning machine. The first branch pipe 12 is connected to the side of the top of the main pipe 11 and extends from back to front. The middle spray arm 2 is connected to the outlet end of the first branch pipe 12. The second branch pipe 13 is connected to the top of the top of the main pipe 11 and includes a vertical section extending from bottom to top along the water flow direction and a transverse section extending forward from the top of the vertical section. The top spray arm 3 is connected to the outlet end of the second branch pipe 13 and is located directly above the middle spray arm 2, and is coaxially arranged with the middle spray arm 2. This is the conventional structure of the cleaning machine, and will not be described in detail here.

[0031] In this embodiment, a nozzle 121 is provided on the top wall of the front part of the first branch pipe 12; a mounting base 122 is provided on the top side of the first branch pipe 12 above the nozzle 121. Specifically, the mounting base 122 is generally inverted U-shaped and is a flexible component.

[0032] In this embodiment, the fan blade 4 is arranged in the middle position opposite to the top spray arm 3, and is rotatably connected to the mounting base 122 via a rotating shaft 41. When no external force is applied to the fan blade 4, the rotating shaft 41 extends in the vertical direction.

[0033] In this embodiment, the fan blade 4 is located on the flow path of the water flowing out of the nozzle 121, so that the fan blade 4 can rotate around its own axis under the action of the water flow and splash the water. In addition, since the mounting base 122 is a flexible component, the mounting base 122 can deform under the action of the water flow on the fan blade 4.

[0034] The working principle of this embodiment is as follows: During cleaning, the water pump of the cleaning machine pumps water into the inner water pipe 1. The water flow in the main pipeline 11 is supplied to the middle spray arm 2 and the top spray arm 3 through the first branch pipeline 12 and the second branch pipeline 13 respectively. At the same time, the spray hole 121 generates a water flow with a certain head. The water flow impacts the fan blade 4 and drives the fan blade 4 to rotate. The rotation of the fan blade 4 disperses the water flow and cleans the tableware in the dead corners through the splashing effect, avoiding the cleaning dead corners in the central area. At the same time, since the mounting base 122 is a flexible part, it can generate a certain angle deviation while the water flow impacts, thereby achieving multi-angle cleaning and high coverage.
