[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-7The present invention is a washable spray arm, which is used in a dishwasher. It includes a spray arm body 1 and end caps 2 disposed at both ends of the spray arm body 1. A mortise and tenon structure is provided between the spray arm body 1 and the end caps 2. The spray arm body 1 and the end caps 2 are connected by the mortise and tenon structure, so that the spray arm body 1 and the end caps 2 can be disassembled and assembled.

[0025] The mortise and tenon structure includes slots 3 at both ends of the spray arm body 1 and a retaining rib 4 at one end of the end cap 2. The retaining rib 4 is inserted into the slots 3 to connect the spray arm body 1 and the end cap 2.

[0026] The slot 3 is a dovetail groove, and the shape of the retaining rib 4 matches the shape of the slot 3. The dovetail groove enables quick assembly and disassembly of the spray arm body 1 and the end cap 2 without the need for additional tools or fasteners. It also makes the connection between the spray arm body 1 and the end cap 2 very stable and not easy to loosen.

[0027] The spray arm body 1 has a first cleaning port 5 at each end, which connects to the interior of the spray arm body 1. When the spray arm body 1 and the end cap 2 are connected, the end cap 2 closes the first cleaning port 5. When the spray arm body 1 and the end cap 2 are disassembled, the first cleaning port 5 opens, allowing the spray arm body 1 to pass through in the length direction. When the spray arm is cleaned, water is introduced into the first cleaning port 5 at one end of the spray arm body 1. The water flows through the entire spray arm body 1 and causes dirt inside the spray arm body 1 to flow out from the first cleaning port 5 at the other end of the spray arm body 1, preventing dirt inside the spray arm body 1 from clogging the spray holes 10 of the spray arm body 1.

[0028] The slots 3 are distributed laterally on the first cleaning port 5, and the retaining ribs 4 are distributed laterally on the end cap 2.

[0029] Two sets of slots 3 are provided, and the two sets of slots 3 are located on both sides of the first cleaning port 5. Each set of slots 3 includes several slots 3. Two retaining ribs 4 are provided and located on both sides of the end cap 2. Each retaining rib 4 is inserted into the corresponding set of slots 3. In this embodiment, each set of slots 3 includes 3 slots 3. By inserting the retaining ribs 4 into multiple slots 3, the connection between the spray arm body 1 and the end cap 2 is made more secure.

[0030] The spray arm body 1 has slots 3 on both sides, and the retaining ribs 4 are inserted into the slots 3 through the side of the spray arm body 1. During installation, the end cap 2 is inserted into the end of the spray arm body 1 from the side so that the retaining ribs 4 are inserted into multiple slots 3. During disassembly, the end cap 2 is pulled out towards the side of the spray arm body 1 so that the retaining ribs 4 are disengaged from the slots 3.

[0031] The spray arm body 1 is provided with several reinforcing ribs 6, and the slots 3 are respectively provided at both ends of the reinforcing ribs 6. The reinforcing ribs 6 are provided along the length direction of the spray arm body 1, and the reinforcing ribs 6 are distributed on the spray arm body 1 along the width direction of the spray arm body 1. The reinforcing ribs 6 can improve the structural strength of the spray arm.

[0032] The spray arm body 1 has a first positioning surface 7 at both ends, which is located around the first cleaning port 5. The end cap 2 has a second positioning surface 8 at one end, which is located around the second cleaning port 9. The retaining rib 4 is set on the second positioning surface 8. The first positioning surface 7 and the corresponding second positioning surface 8 fit together to achieve left and right positioning between the spray arm body 1 and the end cap 2.

[0033] The end cap 2 is provided with a second cleaning port 9 at one end. The second cleaning port 9 is connected to the inside of the end cap 2. Water is introduced into the second cleaning port 9 to clean the dirt inside the end cap 2.

[0034] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
