Description

Technical Field

[0001] The utility model relates to a new type of dishwasher spray arm.

Background Art

[0002] A dishwasher is a device that can automatically clean tableware such as bowls, chopsticks, plates, dishes, knives and forks. In actual use, it is found that due to the changing positions of various tableware by users, and the different cleaning difficulties of different tableware, as well as the problem of easy emergence of spraying dead angles, etc., some tableware is often not thoroughly cleaned when the dishwasher is cleaning the tableware. To solve this problem, some dishwasher manufacturers solve the problem of incomplete cleaning by setting an extended working time of the dishwasher, but this will also cause the problem of increased water consumption due to too long cleaning time. Some people also solve the cleaning problem by adding spray arms at other positions inside the washing cavity, but there is a problem of high cost.

[0003] Therefore, it is necessary to make further improvements to it.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, this application provides a new type of dishwasher spray arm, which includes a spray arm base 1, a main spray arm 2, a face-rotating spray arm 3, and a side-swinging spray arm 4. The main spray arm 2 is rotatably connected to the spray arm base 1. A first water outlet 5 is provided in the middle position of the upper end face of the main spray arm 2. Second water outlets are respectively provided at the left and right ends of the main spray arm 2. The face-rotating spray arm 3 is rotatably connected to the first water outlet 5, and the first water outlet is communicated with the waterway inside the face-rotating spray arm. After water enters the face-rotating spray arm from the main spray arm, under the pressure and impact of the water flow, the face-rotating spray arm can rotate relative to the main spray arm; the side-swinging spray arm 4 is rotatably connected to the second water outlet, and the second water outlet is communicated with the waterway inside the side-swinging spray arm. The side-swinging spray arm can swing relative to the main spray arm 2. After water enters the side-swinging spray arm from the main spray arm, under the pressure and impact of the water flow, the side-swinging spray arm can rotate relative to the main spray arm, thereby indirectly increasing the spraying area of the spray arm and solving the problem of spraying dead corners caused by the placement of tableware.

[0018] A fixed gear 6 is provided on the spray arm base 1. A transmission mechanism is provided between the side-swinging spray arm and the main spray arm. The transmission mechanism includes a moving part 7 and a moving gear 8. The transmission part is slidably connected to the main spray arm. An inclined slot 9 and a flat slot 10 are formed in the transmission part 7. The side-swinging spray arm 4 has a first extending part 11 extending into the inclined slot. The moving gear 8 is rotatably connected to the main spray arm 2 and meshes with the fixed gear. A second extending part 12 extending into the flat slot is provided on the moving gear. The second extending part is eccentrically arranged on the moving gear. When the moving gear 8 rotates, the transmission part 7 makes a linear reciprocating motion under the cooperation of the second extending part 12 and the flat slot 10, and the side-swinging spray arm 4 makes a reciprocating rotation relative to the main spray arm 2 under the cooperation of the first extending part 11 and the inclined slot 9. Specifically: when water enters the main spray arm, the main spray arm rotates under the action of the water source pressure. When the main spray arm rotates, since the moving gear meshes with the fixed gear, the moving gear will also rotate. During the process of the second extending part provided on the moving gear rotating from the initial position to the 180-degree position, the second extending part pushes the transmission part forward. When the second extending part rotates from the 180-degree position to the 360-degree position, the second extending part pulls the transmission part back. The rotation of the moving gear realizes the reciprocating motion of the transmission part; when the transmission part reciprocates back and forth, the first extending part reciprocates at both ends of the inclined slot, thereby realizing the reciprocating swing (rotation) of the side-swinging spray arm relative to the main spray arm.

[0019] A limiting part 13 is provided below the transmission part 7. The limiting part is fixedly connected to the main spray arm 2 to prevent the transmission part from loosening. The transmission part is provided with a positioning sliding slot 14, and the limiting part has a positioning slider 15 cooperating with the positioning sliding slot. The limiting part is fixed to the main spray arm by screws. Under the cooperation of the positioning sliding slot and the slider, the reciprocating linear motion of the transmission part can be ensured.

[0020] The second water outlet is provided with an insertion pipe body 16, and a channel 17 for inserting the insertion pipe body is formed on the side-swinging spray arm 4. One or more sealing rings are provided on the insertion pipe body 16 to ensure the sealing performance.

[0021] The first water outlet 5 is provided with a step 18. The surface-rotating spray arm 3 has a water inlet 19 that is docked with the first water outlet. Elastic catch hooks 20 that are buckled with the step are provided around the water inlet. By buckling the elastic catch hooks with the step, it not only does not affect the rotation of the surface-rotating spray arm, but also can assemble the surface-rotating spray arm on the main spray arm.

[0022] A vertical spray port 21 and / or an inclined spray port 22 are provided above the surface-rotating spray arm 3 and the side-swinging spray arm 4. By providing spray ports in different directions and angles, the tableware can be better flushed and cleaned.

[0023] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention shall be included in the protection scope recorded in the claims.
