When the shelf 3 is flipped to be horizontally arranged above the bowl basket 1, the auxiliary spray arm 4 is horizontally arranged as the shelf 3 is flipped and sprays a water column to the shelf 3 above it. When the shelf 3 is flipped to be vertically stored in the side of the bowl basket 1, the auxiliary spray arm 4 is vertically arranged as the shelf 3 is flipped and disconnected from the water source.

[0028] The water tank body is provided with an inner water pipe 7 extending vertically close to the inner side wall of the water tank body 1. The lower end of the inner water pipe 7 is a water inlet end connected to the return water at the bottom of the water tank body. In this embodiment, a water pump 6 is provided at the bottom of the water tank body. The lower end of the inner water pipe 7 is connected to one water outlet of the water pump 6. The other water outlet of the water pump 6 is connected to the water inlet of the main spray arm 2. The upper part of the side of the inner water pipe 7 is provided with a water outlet 71 that can be connected or disconnected with the auxiliary spray arm 4. The water outlet 71 is provided with a switch that can control its opening and closing. This structure facilitates the switching of the fluid delivery state according to the state of the shelf 3.

[0029] The side wall of the inner water pipe 7 is provided with a slot 72 arranged around the water outlet 71, and a valve plate 73 (i.e., a switch member) is detachably provided in the slot 72. When the valve plate 73 is removed from the slot 72, the water outlet 71 is opened, and when the valve plate 73 is inserted into the slot 72, the water outlet 71 is closed. The structure is operated by the user, and the user can choose whether to open the water outlet and place the dishes to be washed on the shelf according to actual needs.

[0030] The slot 72 is in an eight-shaped structure with a small upper end and a large lower end, and the side wall of the inner water pipe 7 in the slot 72 forms an inclined surface 721 which gradually tilts from bottom to top toward the shelf 3. The water outlet 71 is located in the middle of the inclined surface 7211, and the valve plate 73 can be inserted into the slot 72 from top to bottom to seal with the inclined surface 721. With such a structure, as the valve plate 73 is inserted downward, the pressing force between the slot 72 and the valve plate 73 becomes greater and greater, thereby improving the sealing effect. When the shelf 3 and the auxiliary spray arm 4 are not in use, the sealing of the water outlet 71 is maintained to avoid fluid pressure loss.

[0031] The inclined surface 721 at the lower edge of the water outlet 71 is partially tilted from top to bottom gradually toward the shelf 3 to form a limiting surface 722 that can limit the front edge of the valve plate 73 after the valve plate 73 is inserted downward into the slot 72. This structure is conducive to further improving the sealing of the water outlet 71 in a closed state.

[0032] The auxiliary spray arm 4 is detachably connected to the water outlet 71 through the water conduit 8 extending along the shelf 3. This structure facilitates the disassembly and assembly between the auxiliary spray arm 4 and the inner water pipe 7, so as to facilitate its switching position with the shelf 3.

[0033] The water inlet end face of the water guide pipe 8 is inclined from top to bottom along the water flow direction to form an inclined edge 81 matching the inclined surface 721. The water inlet end of the water guide pipe 8 is also provided with convex clamps 82 located on both sides of the inclined edge 81 and cooperating with the clamping groove 72 to limit the position. This structure is conducive to improving the connection sealing between the water guide pipe and the inner water pipe 7 when the auxiliary spray arm 4 is connected to the water source, and avoiding water leakage here and affecting the water pressure.

[0034] In this embodiment, the side wall of the bowl basket 1 is a U-shaped semi-enclosed structure, and the shelf 3 covers the opening 11 of the semi-enclosed structure when it is stored in the side of the bowl basket 1. Such a structure not only facilitates the smooth flipping of the shelf 3, but also blocks the tableware in the bowl basket 1 when the shelf 3 is stored, and does not occupy additional space, thus killing two birds with one stone.

[0035] When the shelf 3 is flipped to be stored vertically on the side of the bowl basket 1, the shelf 3 forms a side wall for blocking the opening 11 of the U-shaped semi-enclosed structure of the bowl basket 1; when the shelf 3 is flipped to be arranged horizontally on the bowl basket 1, the shelf 3 is used to place the dishes to be washed. With the above structure, the tableware in the bowl basket 1 can be blocked when the shelf 3 is stored; when the shelf 3 is arranged horizontally, it can be used to expand the tableware placement area to meet more washing needs of users.

[0036] The bottom edge of the bowl basket 1 is partially concave inward to form a notch 12 for positioning one end of the auxiliary spray arm 4. When the shelf 3 is flipped over to be vertically stored on the side of the bowl basket 1, the notch 12 clamps one end of the auxiliary spray arm 4 therein so that the auxiliary spray arm 4 remains in a vertically extended state. The above structure can position the auxiliary spray arm 4 when the shelf 3 is stored, preventing the auxiliary spray arm 4 from rotating and interfering with the tableware in the bowl basket 1.

[0037] The edge of the opening 11 of the U-shaped semi-enclosed structure of the bowl basket 1 is provided with a first guide opening 10 extending vertically, and correspondingly, the side edge of the shelf 3 is provided with a second guide opening 20 extending along the length direction thereof, and a guide member 5 is provided between the first guide opening 10 and the second guide opening 20 to enable the two to slide and cooperate during the turning process of the shelf 3. With such a structure, the shelf 3 can be turned stably with the edge of the bowl basket 1 as support.

[0038] The present embodiment is provided with a flippable shelf 3, which can be used to place dishes to be washed when placed horizontally, thereby increasing the amount of dishes to be washed. When the shelf 3 is vertically stored at the side of the bowl basket 1, it does not affect the original amount of dishes placed in the bowl basket 1. When the shelf 3 is in use, the auxiliary spray arm 4 sprays toward the shelf 3 to wash the dishes on the shelf 3. The auxiliary spray arm 4 cooperates with the main spray arm 2, which is conducive to eliminating blind spots in washing and improving the washing effect.
