Description

Washing machine spray arm rotation structure

technical field

The utility model relates to a spray arm of a washing machine, in particular to a rotating structure of the spray arm of a washing machine, which belongs to the field of medical equipment. the

Background technique

The structure of the spray arm used in large washing machines is often changed according to the size of the equipment, so the length of the spray arm will change with the size of the inner chamber and the size of the item to be cleaned. The round hole-shaped spray hole, the water outlet The shape is a simple columnar water flow, which sprays to the surface of the object to be cleaned in a single way, and it is easy to cause the situation that the spray cannot be sprayed. The rotating shaft structure of the spray arm is the key component for the flexible rotation of the spray arm. In addition, the rotating shaft of the spray arm is often prone to water leakage Phenomenon, when the flow rate and pressure of the sprayed circulation pump are sufficient, the impact of water leakage on the equipment is not great, but when the pressure is insufficient, the impact of water leakage on the overall cleaning effect is very obvious. the

Utility model content

According to the deficiencies of the prior art above, the technical problem to be solved by the utility model is: to provide a spray arm rotating structure of the washing machine that can overcome the above defects, has good cleaning effect, is easy to install and disassemble, and is not easy to leak. the

The technical scheme that the utility model solves its technical problem adopts is:

The rotating structure of the spray arm of the cleaning machine includes pipe fittings, which are characterized in that: the two ends of the pipe fittings are welded with spray arms, the spray arms are provided with spray nozzles, the inside of the pipe fittings is equipped with a rotating shaft, and the top of the pipe fittings is provided with a fixed retaining ring, which is sleeved on the At the top of the rotating shaft, the pipe is fixed on the rotating shaft through a pin passing through the fixed retaining ring and the top of the rotating shaft. the

The rotating shaft structure of the spray arm of the cleaning machine is very easy to disassemble and install, and the spray pipe can be cleaned and replaced conveniently. The rotating shaft structure can ensure that there is no water leakage during the rotation, and the pressure and flow of the spray arm can be guaranteed. , to achieve the best cleaning effect. the

The spraying arm is provided with three groups of spraying nozzles, each group of spraying nozzles has 2, the first group of spraying nozzles is at 90 degrees to the spraying arm, the second group of spraying nozzles is at 60 degrees to the spraying arm, and the third group of spraying nozzles is at 90 degrees to the spraying arm. The arms are at 45 degrees, and the spray arms at both ends of the pipe are center-symmetrical. The spray arms at both ends have a center-symmetrical structure, and every two spray nozzles have a certain angle difference, which can improve the cleaning effect and ensure better rotation of the spray arms. the

The rotating shaft is I-shaped, and there is a gap between the rotating shaft and the pipe fitting. Four water inlet holes are provided on the rotating shaft, corresponding to the four water inlet holes on the water inlet pipe, and there is a gap between the rotating shaft and the pipe fitting, so that the water in the water inlet pipe can enter the spray arm more smoothly. the

The spray arm is cylindrical. The position of the spray nozzle can be conveniently designed. the

The spray nozzles are fan-shaped. The fan-shaped spray nozzle design on the spray arm can ensure the spray pressure and spray surface, and the fan-shaped nozzle can radiate to every point within the spray range, reducing the dead angle of cleaning. the

The beneficial effect of the utility model is: the rotating structure of the spray arm of the cleaning machine adopts a cylindrical structure, which can be directly welded with sanitary pipe fittings, and the length and the position of the spray port can be changed according to the actual design. The nozzle design can ensure the spray pressure and spray surface. The fan-shaped nozzle can radiate to every point within the spray range, reducing the dead angle of cleaning. The structure of the rotating shaft is very easy to disassemble and install, and it is convenient to clean and replace the spray pipe. . The structure of the rotating shaft can ensure no water leakage during the rotation, ensure the pressure and flow of the spray arm, and achieve the best cleaning effect. the
