Description

Technical Field

[0001] The utility model relates to the technical field of dishwasher accessories, in particular to a slag discharge structure of a dishwasher cleaning arm. Background Art

[0002] After the washing arms in the dishwasher are used for a long time, dirt will accumulate in the washing arms. Therefore, a slag discharge device is generally provided on both sides of the washing arms for discharging slag.

[0003] The existing slag discharge device includes a plug, which is generally threadedly connected to the cleaning arm. This connection method makes the disassembly and assembly time of the slag discharge device longer.

[0004] For example, the patent with publication number CN202313203U discloses a slag discharge structure of a dishwasher washing arm, which includes a washing arm body, slag discharge ports on both sides of the washing arm, and a plug for sealing the slag discharge ports, and the plug is threadedly connected to the slag discharge port.

[0005] Another example is a dishwasher cleaning arm disclosed in the patent publication number CN117562471 A, referring to the accompanying drawings of the specification. Figure 2 and Figure 3 The plugs on both sides of the cleaning arm are connected to the body by threaded connection.

[0006] It can be seen from the above patent disclosures that the plugs on the existing slag discharge devices are all threadedly connected to the cleaning arms, which makes the disassembly and assembly time of the slag discharge device relatively long.

[0007] Therefore, there is room for improvement in the disassembly and assembly speed of the existing slag discharge device. Utility Model Content

[0008] In order to solve the above technical problems, the purpose of the utility model is to disclose a slag discharge structure of a dishwasher washing arm with quick disassembly.

[0009] The technical solution adopted by the utility model to solve the problem is:

[0010] A slag discharge structure of a dishwasher washing arm comprises a washing arm body and a slag discharge device, wherein the washing arm body is provided with a mounting hole adapted to the slag discharge device, and the slag discharge device comprises a plug; a step surface is provided on the inner wall of the mounting hole, an avoidance hole is provided on the step surface, and a protrusion is provided on the plug; the protrusion passes through the avoidance hole and then rotates a certain angle to abut against the bottom of the step surface.

[0011] As a further improvement of the above technical solution, the slag discharge device also includes a sealing ring, and the sealing ring is crimped between the plug and the step surface.

[0012] As a further improvement of the above technical solution, the upper end surface of the protrusion is an inclined surface, and the inclined surface is inclined toward the rotation direction of the protrusion.

[0013] As a further improvement of the above technical solution, the plug includes a cap body and a column body that are integrally arranged, the diameter of the column body is smaller than the diameter of the cap body, and the protrusion is arranged on the column body.

[0014] As a further improvement of the above technical solution, the upper end surface of the cap body is provided with two semicircular grooves, and the two semicircular grooves are symmetrically arranged; a straight groove is provided in the middle of the two semicircular grooves.

[0015] As a further improvement of the above technical solution, the number of the avoidance holes is more than two, and the number of the protrusions corresponds to the number of the avoidance holes.

[0016] The beneficial effect of the utility model is that the utility model arranges a step surface on the inner wall of the installation hole in the form of a snap, and an avoidance hole is arranged on the step surface. After the protrusion on the plug passes through the avoidance hole, it abuts against the bottom of the step surface by rotation, thereby completing the locking of the slag discharge device. The operation is convenient and the disassembly and assembly speed of the slag discharge device is improved. BRIEF DESCRIPTION OF THE DRAWINGS
