Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 2-3, the embodiment provides a side spraying device of a dishwasher, which comprises a spraying seat 1 arranged on the side wall of an inner container of the dishwasher, a spraying bracket 3 connected to the spraying seat 1, and a spraying arm 2 arranged between the spraying seat 1 and the spraying bracket 3; the spray arm 2 can rotate coaxially relative to the spray bracket 3 and the spray seat 1. The spraying arm 2, the spraying bracket 3 and the spraying seat 1 are coaxially rotated, so that the phenomenon that the spraying arm 2 is inclined downwards in the working process when the spraying device is arranged on the side wall of the inner container of the dish-washing machine is prevented; meanwhile, the spraying bracket 3 is connected to the spraying seat 1, so that the phenomenon that the spraying arm 2 inclines downwards in the working process when the spraying device is arranged on the side wall of the inner container of the dish-washing machine is further prevented. Meanwhile, the spraying device is arranged on the side wall of the inner container of the dish washing machine, so that the tableware is prevented from blocking water flow, the tableware placing space is enlarged, and the cleaning effect is improved.

Specifically, in this embodiment, the rotation center of the opposite side of the spray bracket 3 and the spray arm 2 is provided with the connecting shaft 32, and the position of the spray arm 2 corresponding to the connecting shaft 32 is provided with the groove 222. The connecting shaft can also be arranged on the spray arm 2, and the groove is arranged on the spray bracket 3, so that the spray arm 2 can rotate relative to the spray bracket 3 and the spray seat 1 in the same axial line.

The spraying seat 1 comprises a spraying seat body 11 connected to the side wall of the inner container of the dish washing machine and a connecting column 12 arranged on the other side of the spraying seat body 11; the spray arm 2 is sleeved outside the connecting column 12 and can rotate relative to the connecting column 12.

The spraying seat body 11 is buckled and connected with the spraying bracket 3. Specifically, one side of the spray seat body 11, on which the connecting column 12 is arranged, is provided with a plurality of positioning columns 111, and the spray support 3 is provided with positioning holes 33 at positions corresponding to the positioning columns 111; a plurality of clamping platforms 112 are arranged on the spray seat body 11, and clamping holes 34 are arranged on the spray bracket 3 corresponding to the clamping platforms 112. During installation, the positioning columns 111 are inserted into the corresponding positioning holes 33 to position the spray support 3, and then the clamping tables 112 are buckled into the corresponding clamping holes 34 to connect the spray support 3 to the spray seat body 11. Referring to fig. 2, in this embodiment, two positioning columns 111 are respectively disposed on two sides of the connecting column 12, and two positioning holes 33 are disposed on the corresponding spraying bracket 3; the four clamping platforms 112 are symmetrically arranged at two sides of the spraying base body 11, and four clamping holes 34 are correspondingly arranged on the spraying bracket 3. In this embodiment, the spraying base body 11 and the spraying bracket 3 can be connected by screws, or the spraying base body 11 and the spraying bracket 3 can be connected by other methods, only the spraying bracket 3 can be connected to the spraying base body 11 without relative rotation and movement, and therefore, the description is omitted.

In this embodiment, the spray arm 2 includes a first arm 21 sleeved outside the connecting column 12 and capable of rotating relative to the connecting column 12, and a second arm 22 connected to the first arm 21 in a buckling manner and rotatably connected to the spray bracket 3; the first arm body 21 and the second arm body 22 form a spraying cavity 23, a spraying hole (not shown in the figure) communicated with the spraying cavity 23 is formed in the spraying arm 2, and a water injection hole 13 which sequentially penetrates through the connecting column 12, the spraying base body 11 and the spraying cavity 23 is formed in the spraying base 1. High-pressure rivers pass through water injection hole 13 and get into in spraying chamber 23, spray arm 2 and can rotate for spraying seat 1, spray support 3 under the effect of high-pressure rivers, at the continuous rotatory in-process of spray arm 2, spray the rivers in the chamber 23 and spray to the dish washer inner bag through spraying the hole in, wash the tableware.

In this embodiment, a plurality of protrusions 211 are uniformly distributed on the first arm 21 along the circumferential direction thereof, and a plurality of insertion holes 221 are formed in the second arm 22 at positions corresponding to the protrusions 211. The first arm 21 and the second arm 22 are snap-fit connected by inserting the protrusions 211 into the corresponding insertion holes 221. In this embodiment, the first arm 21 and the second arm 22 may be connected in other manners, such as welding, and only the spraying cavity 23 is formed after the first arm 21 and the second arm 22 are connected, which is not described herein again. The groove 222 is disposed on a side of the second arm 22 away from the first arm 21.

As a preferred technical scheme, a plurality of connecting ribs 31 which form a net structure are arranged on one side of the spraying bracket 3 which is not connected with the spraying seat 1. Through setting up splice bar 31, can locate spray arm 2 and spray in the support 3 and make rivers can follow the gap blowout between two adjacent splice bars 31, for spray arm 2 provides the space of injection, prevent that the tableware from directly touchhing spray arm 2 and sheltering from the rivers, improved the cleaning performance. Referring to fig. 2, in the present embodiment, four connecting ribs 31 are symmetrically disposed. When the connecting ribs 31 are arranged too little, tableware can possibly pass through the gap between two adjacent connecting ribs 31 to contact the spray arm 2, so that water flow is blocked, and the cleaning effect is reduced; when the connecting ribs 31 are excessively arranged, the gap between every two adjacent connecting ribs 31 is reduced, the connecting ribs 31 stop the water flow from being sprayed, and the cleaning effect is reduced.

The embodiment also provides a dishwasher, which comprises a plurality of the dishwasher lateral spraying devices, and each dishwasher lateral spraying device is arranged on the side wall of the dishwasher liner. The problem of the spray arm 2 downward sloping phenomenon that appears when installing spray set at dish washer inner bag lateral wall is solved, enlarged the tableware simultaneously and placed the space, made the tableware can not contact spray arm 2, improved the cleaning performance.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
