[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-9 This guide rail assembly includes a guide rail 1 disposed on the side of the inner liner 3, a support part 2 for supporting a bowl basket 17 disposed on the guide rail 1, the bowl basket 17 being slidably disposed on the support part 2, a support head 4 protruding outwardly disposed on the side of the inner liner 3, a connector 5 disposed on the side of the guide rail 1, the connector 5 being inserted into the support head 4, and the guide rail 1 being supported and mounted on the support head 4 through the connector 5.

[0027] The support part 2 is L-shaped, and its side is provided with a limiting edge 6 for limiting the left and right movement of the bowl basket 17. The surface of the support part 2 is smooth, which makes it easy for the bowl basket 17 to slide into or out of the inner liner 3. The limiting edge 6 can prevent the bowl basket 17 from loosening left and right, and also prevent the bowl basket 17 from scratching the side wall of the inner liner 3 when it slides into or out of the inner liner 3.

[0028] The rear end of the bearing part 2 is provided with a stop block 7. When the bowl basket 17 slides into the inner liner 3 through the bearing part 2, it is limited on the stop block 7. The stop block 7 is used to stop the bowl basket 17 from sliding into the inner liner 3 and prevent the bowl basket 17 from colliding with the rear side of the inner liner 3 when it slides into the inner liner 3.

[0029] It also includes a seal 9, which is disposed between the connector 5 and the support head 4. The connector 5 is supported on the support head 4 by the seal 9, thereby allowing the guide rail 1 to be supported on the support head 4. The seal 9 is a sealing ring, which can prevent water inside the inner liner 3 from leaking out of the inner liner 3 through the gap between the connector 5 and the support head 4.

[0030] The support head 4 has a mounting hole 8, and the connector 5 is inserted into the mounting hole 8.

[0031] The support head 4 is provided with a mounting groove 10 that connects to the mounting hole 8. The mounting hole 8 is located in the center of the mounting groove 10. The seal 9 is installed on the mounting groove 10 and is fitted onto the connector 5.

[0032] The support head 4 is provided with a fixing hole 11, and the connector head 5 is provided with a fixing post hole 12. The fastener 13 (screw) passes through the fixing hole 11 and is fastened to the fixing post hole 12 so that the guide rail 1 is fixed on the inner liner 3.

[0033] The inner side of the guide rail 1 is provided with a clearance notch 15 for avoiding the spray arm 14. The clearance notch 15 is located below the support part 2. The clearance notch 15 allows the left and right ends of the spray arm 14 to extend into the guide rail 1, making the structure of the dishwasher more compact.

[0034] The inner side of the guide rail 1 is provided with an outwardly inclined surface 16, and the clearance notch 15 is provided on the inclined surface 16. The inclined surface 16 is also used to avoid the spray arm 14.

[0035] This dishwasher includes an inner tub 3, inside which a dish rack 17 and a spray arm 14 are disposed. Guide rail assemblies are respectively disposed on both sides of the inner tub 3. Casters are disposed at the bottom of the dish rack 17 and are slidably supported on the support part 2. The guide rails 1 are respectively located on the left and right sides of the spray arm 14. The dish rack 17 slides on the support part 2 via the casters, thereby allowing the dish rack 17 to slide into or slide out of the inner tub 3. The spray arm 14 is a lower spray arm and is located at the bottom of the inner tub 3. The guide rail assembly and the support head 4 are also located at the bottom of the inner tub 3.
