DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-3 The bidirectional spray mechanism of the dishwasher in the embodiment has the advantage of good cleaning effect.

[0020] Specifically, the device comprises two three-way heads 1; the two three-way heads 1 are connected through a connecting pipe 2; a connecting head 3 is connected below the lower three-way head 1;

[0021] An adjusting member 4 is arranged on the lower three-way head 1;

[0022] Two spraying arms 5 are rotatably arranged on the adjusting member 4 and below the upper three-way head 1 respectively;

[0023] A power mechanism 6 is arranged on the outer wall of the lower three-way head 1 and connected with the adjusting member 4, and the power mechanism 6 is used to drive the adjusting member 4 to adjust the angle of the lower spraying arm 5.

[0024] In this embodiment, when needed, the external water pump is first connected with the lower three-way head 1 through the connecting head 3, and when the water pump is working, the water flows into the two three-way heads 1 and the connecting pipe 2 in sequence, and due to the action of the force, the water is sprayed from the spraying arms 5, and due to the fact that the nozzles on the spraying arms 5 are usually arranged obliquely (prior art), the spraying arms 5 rotate under the action of the backwash of the water flow, so as to clean the dishes in the dishwasher and expand the spraying range, increase the cleaning effect, and at the same time, the power mechanism 6 arranged can drive the adjusting member 4 to adjust the angle of the lower spraying arm 5, so that the lower spraying arm 5 rotates while being adjusted in angle, which not only increases the spraying range, but also adjusts the spraying angle, so as to clean the dirt on some health dead angles of the dishes, thereby improving the cleaning effect.

[0025] Specifically, referring to Figure 3 , the adjusting member 4 comprises two mounting plates 41 arranged above the lower three-way head 1; two rotating rods 42 rotatably arranged in the two mounting plates 41 and penetrating through the mounting plates 41 at two ends respectively; a bearing frame 43 arranged between the two rotating rods 42; the bearing frame 43 and the lower three-way head 1 are connected through a hose 44, and the lower spraying arm 5 is connected with the lower three-way head 1 through the hose 44; two shaft rods 45 arranged on the opposite sides of the two rotating rods 42 respectively; and a guide ball 46 arranged at the end of the shaft rod 45.

[0026] In this embodiment, when the guide ball 46 is driven by the power mechanism 6, the rotating rod 42, the bearing frame 43 and the lower spraying arm 5 can be sequentially rotated through the shaft rod 45, so as to adjust the angle of the spraying arm 5 during spraying.
