[0058] In order to ensure maximum utilization of space, the shelf body 1 is generally square in design, but the spray arm 5 is generally configured as a fan structure with a rotating shaft arranged in the middle and rotating blade portions 8 radially protruding and extending to opposite sides; the two rotating blade portions 8 of the spray arm 5 are respectively provided with water spray holes that can spray water outward in a tangential or approximately tangential direction, so that the spray arm 5 can be driven by the sprayed water flow to rotate under the influence of the recoil force. Because the length of the upper spray arm 501 is less than the diagonal length of the upper shelf 101, it is difficult for the water flow of the upper spray arm 501 to spray the objects to be cleaned at the four corners of the upper shelf 101, such as glasses and other objects with deeper calibers, to the four corners of the upper shelf 101, so that the cleanliness of the inner cavity of the objects to be cleaned cannot meet the cleaning requirements of the users. In order to solve the above problems, the present invention makes the following arrangements.

[0059] like Figures 1 to 4 and Figure 7 As shown, in the embodiment of the present invention, a focusing reflective cleaning member 12 is provided at the bottom of the four corners of the upper shelf 101. The focusing reflective cleaning member 12 can be a separate caliper set at the four corners of the bottom of the upper shelf 101, or can be integrated with the upper shelf 101 and set at the four corners of the bottom of the upper shelf 101. The top opening of the focusing reflective cleaning member 12 corresponds to the opening of the object to be cleaned, such as a glass, placed in the upper shelf 101.

[0060] like Figures 1 to 4 and Figure 7 As shown, in the embodiment of the present invention, the focusing reflective cleaning member 12 includes a reflecting surface 120 extending downward from the bottom of the upper shelf 101 and offset from the edge of the upper shelf 101 toward the center of the upper shelf 101. The inclination angle of the reflecting surface 120 is consistent with the placement angle of the glass cup in the upper shelf 101. The reflecting surface 120 is configured as an inclined surface that bends away from the bottom of the upper shelf 101. The extended top end of the reflecting surface 120 is at least partially in a horizontal position lower than the lowest end horizontal position of the upper spray arm 501 to ensure that the water sprayed by the upper spray arm 501 to the focusing reflective cleaning member 12 can be focused and reflected by the focusing reflective cleaning member 12.

[0061] like Figures 1 to 4 and Figure 7As shown, in the embodiment of the present invention, the focusing reflection cleaning member 12 further includes a curved baffle 121, whose top is flush with the top of the reflection surface 120, whose two sides are connected to the two sides of the reflection surface 120, and which extends downward along the bottom of the upper shelf 101 and is inclined in the opposite direction to the inclination of the reflection surface 120. The curved baffle 121 is configured as an arc-shaped plate that is bent in the opposite direction to the bending direction of the reflection surface 120. The inclination angle of the curved baffle 121 is greater than the inclination angle of the glass placed in the upper shelf 101. The horizontal position of the extended top end of the curved baffle 121 is higher than the spray hole 60 on the top surface of the upper spray arm 501. 1, so that at least part of the water flow reflected by the reflecting surface 120 is focused and reflected by the curved baffle 121 and sprayed into the glass placed on the upper shelf 101, and the splashing water flow that is not reflected into the glass is blocked; the focusing and reflecting cleaning element 12 is surrounded by the reflecting surface 120 and the curved baffle 121 to form a conical cavity with an open top, and the top opening is coaxially arranged with the opening of the object to be washed above the focusing and reflecting cleaning element 12 in the upper shelf 101, so that the water flow reflected by the focusing and reflecting can flow into the interior of the object to be washed to achieve the purpose of cleaning the object to be washed.

[0062] like Figures 1 to 7 As shown, in the embodiment of the present invention, a hanging rack 9 connected to the side wall of the lower rack 102 is provided at the gap between the upper rack 101 and the lower rack 102, and is used to hold tableware with a large head and a thin body and light weight, such as soup spoons. The hanging rack 9 is connected to the lower rack 102 via a metal rod, and extends along the side connected to the lower rack 102 toward the center of the lower rack 102. The hanging rack 9 is suspended in the gap between the upper rack 101 and the lower rack 102. A cabinet rack 10 is provided on the side of the lower rack 102 close to the hanging rack 9, and is used to hold long and light tableware, such as chopsticks and forks, so as to place and wash some long and light tableware.
