Description

Technical Field

[0001] The utility model relates to a spray arm assembly with an auxiliary spray arm. Background Art

[0002] A dishwasher is a device that can automatically wash tableware such as bowls, chopsticks, plates, dishes, knives and forks. In actual use, it is found that due to the changes in the placement of various tableware by users, the difficulty of cleaning different tableware is also different, and there are problems such as spray dead angles. Therefore, when washing tableware, the dishwasher often has the problem of incomplete cleaning of some tableware. In order to solve this problem, some dishwasher manufacturers solve the problem of incomplete cleaning by setting the dishwasher to extend the working time, but this will cause the problem of increased water consumption due to excessive cleaning time. Some people also solve the cleaning problem by adding spray arms at other locations inside the washing chamber, but there is a problem of high cost.

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

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-2 The present application provides a spray arm assembly with an auxiliary spray arm, which includes a spray arm seat 1, a main spray arm 2 and a branch spray arm 3. The main spray arm 2 is rotatably connected to the spray arm seat 1, and the spray arm seat is provided with a fixed gear 4. The main spray arm 2 is rotatably connected with a moving gear 5 that meshes with the fixed gear. A notch 6 is left on the main spray arm 2 for installing the branch spray arm. The branch spray arm 3 is rotatably connected to the main spray arm 2 and can swing up and down relative to it. The moving gear 5 drives the branch spray arm to swing up and down through a transmission part 7. When the main spray arm rotates relative to the spray arm seat, the moving gear will rotate immediately due to the meshing relationship with the fixed gear, thereby driving the branch spray arm to swing up and down relative to the main spray arm through the transmission part. When the branch spray arm swings up and down, the water output by it will also continuously change position and angle, thereby obtaining a larger spraying area and spraying angle.

[0017] Preferably, the transmission part 7 can move relative to the main spray arm 2, one end of the transmission part is connected to the branch spray arm 3, and the other end of the transmission part is provided with a connecting groove 8. The moving gear 5 is provided with an eccentric connecting column 51 extending into the connecting groove. When the moving gear 5 rotates, the transmission part 7 can move back and forth relative to the main spray arm 2 and drive the branch spray arm 3 to swing up and down.

[0018] The transmission part 7 is provided with a limit groove 71, which extends along the reciprocating movement direction of the transmission part. The main spray arm 2 is provided with a limit column 9 extending into the limit groove. With the cooperation of the limit column and the limit groove, the reciprocating movement direction of the transmission part can be ensured, ensuring that the branch spray arm can swing up and down stably.

[0019] The limit column 9 is detachably connected to the main spray arm 2. The limit column has a limit convex edge 91 for preventing the transmission part 7 from detaching from the main spray arm. The limit column can be connected to the main spray arm in the form of a thread, or in a buckle connection, etc., to facilitate the installation and removal of the transmission part.

[0020] The transmission part 7 is provided with a connecting hole 10, and the branch spray arm 3 has a column extending into the connecting hole. The use of this structure can facilitate the connection between the branch spray arm and the transmission part. Preferably, the bottom of the column has an anti-detachment hook part 11, and the connecting hole 10 can be used for the anti-detachment hook part to pass through. The anti-detachment hook part and the connecting hole are staggered, which can further prevent the transmission part from detaching from the main spray arm.

[0021] The fixed gear 4 is fixed on the spray arm seat 1 by screws. The fixed gear 4 is easily installed and removed by screws.

[0022] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
