Example one

The invention relates to a dishwasher 1, a washing component 100 is arranged in the dishwasher 1; the cleaning assembly 100 comprises a basket 102 and a first spray arm 105, wherein the first spray arm 105 sprays cleaning liquid for the object to be cleaned on the basket 102 to clean the object to be cleaned, both the basket 102 and the first spray arm 105 can rotate independently, and the basket 102 and the first spray arm 105 rotate reversely under the driving of different driving sources. Therefore, the relative movement speed of the first spray arm 105 and the article basket 102 can be increased, the cleaning is accelerated, and the cleaning efficiency of the dishwasher 1 is improved.

The basket 102 is generally made of a material that is not easily rusted, such as plastic and stainless steel. In one embodiment, openings are required in the basket 102 to allow cleaning solution, waste water from the dishes, and other soiled materials to escape; the openings can be arranged in any shape and uniformly or non-uniformly distributed on the basket 102; in one embodiment, the openings in the basket 102 are shown as leaks 1021 in FIG. 4, such that cleaning solution and/or residue can exit the plane of the basket 102 through the leaks 1021 and enter the dirt collection device.

In another embodiment, a plurality of criss-cross support bars may be disposed on the basket 102, and the cleaning solution, the waste water from the dishes, and other dirty substances may flow out from the gaps of the support bars.

The rotation shaft 104 of the basket 102 is disposed through the basket 102, and the driving source drives the rotation shaft 104 to rotate to drive the basket 102 to rotate. There are various connection manners of the basket 102 and the rotation shaft, and the rotation shaft of the basket 102 may be detachably connected to the basket 102 or may not be detachably connected to the basket. For later maintenance, the basket is preferably detachably connected to the basket 102 through a rotating shaft.

In one embodiment, in order to rotate the basket 102, a guide 101 is further disposed below the basket 102, and the basket 102 rotates along the guide 101. As shown in fig. 4, the guide rail 101 is further provided with a running rail 1013, the bottom of the basket 102 is provided with a guide wheel 1012, and the basket 102 rotates along the running rail 1013 via the guide wheel 1012.

It should be appreciated that the rotational direction of the basket 102 may be changed by changing the rotational direction of a drive source (e.g., a motor, etc.).

Since the spray area of the cleaning liquid is often an arc-shaped area, the basket 102 is preferably circular so that the cleaning liquid contacts every dish on the basket 102 as much as possible to avoid dead cleaning.

In some embodiments, two or more baskets 102 may be provided to wash more dishes 2 at a time. In one embodiment, the cleaning assembly 100 includes a plurality of baskets 102 spaced apart from one another, and a rotating shaft 104 is disposed through the plurality of baskets 102 such that the driving source can simultaneously drive the plurality of baskets 102 to rotate.

In one embodiment, as shown in fig. 3, a first spray arm 105 is disposed above or below the basket 102 to clean the dishes on the corresponding basket 102, thereby improving the cleaning efficiency.

As shown in FIG. 8, the first spray arm 105 is provided with a plurality of spray holes for spraying the cleaning solution to the dishes 2 on the basket 102. The first spray arm 105 is fixed above or below the basket 102 by a fixing structure, and the first spray arm 105 rotates around its rotation axis. The first nozzle arm 105 can be rotated in at least two ways, and in one embodiment, the first nozzle arm 105 is directly rotated by a rotation shaft thereof, and the rotation shaft is driven by another driving source. In one embodiment, the other drive source may be a motor, in which case the direction of rotation of the first spray arm 105 may be changed by changing the direction of rotation of the drive source. In another embodiment, the other driving source may be a driving force of the cleaning solution, and the first spray arm 105 is driven to rotate by the reaction of the cleaning solution sprayed from the first spray arm 105. At this time, the first nozzle arm 105 is provided with a driving hole 1052, and the cleaning liquid is discharged from the driving hole 1052, and the rotating direction of the first nozzle arm 105 can be changed by adjusting the discharge angle of the driving hole 1052. As shown in fig. 8, the first spray arm 105 is further provided with a washing hole 1051, wherein the washing hole 1051 is mainly used for spraying a washing liquid to wash dishes on the basket.

In order to facilitate the reaction force of the sprayed cleaning solution to push the first spray arm, the first spray arm is a slender structure, and specifically, the first spray arm 105 further includes a communication hole 1047 and two extension arms 1048, the extension arms 1048 are symmetrically arranged around the communication hole 1047, and the cleaning solution enters the two extension arms 1048 through the communication hole 1047.

The plurality of nozzles may be uniformly or non-uniformly distributed on the first nozzle arm 105; preferably, the spray holes are evenly distributed on the first spray arm 105, so that the cleaning solution in the first spray arm 105 is evenly sprayed toward the dishes 2 on the basket 102.

It should be understood that the spraying area formed by the spraying of the cleaning liquid by the first spraying arm is not smaller than the corresponding dish placing area on the basket 102, so as to completely clean the dishes 2. In one embodiment, the first spray arm 105 may be configured to have an overall length that corresponds to the diameter of the circular basket 102 to ensure adequate cleaning of the dishes. It should be appreciated that the overall length of the first spray arm 105 should not impede the installation of the outer housing in which the cleaning assembly is installed with the cleaning assembly 100.
