Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

Embodiment one

As shown in Figure 1, this embodiment provides a spraying device, including at least one spray pipe 1 that is connected to the inner wall of the window pad 10 of the drum washing machine and is arranged close to the inner wall of the window pad 10, each The spray pipe 1 is provided with several spray holes 11 arranged towards the observation window glass of the drum washing machine.

In this embodiment, by arranging the spray pipe 1 and setting several spray holes 11 on the spray pipe 1, the water entering the spray pipe 1 can be sprayed out through several spray holes 11 and sprayed onto the observation window glass. Compared with the use of a single spray nozzle, the area of the spray area is enlarged, the spray effect is improved, and the clothes are cleaned due to the dead angle of washing when the existing spray device is used to wash the observation window glass. unclean problem. In addition, in this embodiment, the spray pipe 1 is fixed on the window pad 10 of the drum washing machine, so that the installation and disassembly of the spray pipe 1 can be realized quickly, and the installation and disassembly methods are simple.

As shown in FIG. 2 and FIG. 3 , the spray pipe 1 in this embodiment has an arc structure, and the central angle corresponding to the spray pipe 1 in the arc structure is determined according to the model of the front-loading washing machine. According to the model of the drum washing machine, the size of the corresponding observation window glass can be determined, and then the size of the central angle corresponding to the spray pipe 1 of the arc structure can be determined, so as to ensure that each area of the observation window glass can be washed, and improve Flushing effect, avoid flushing dead ends.

As shown in FIG. 4 , the spray pipe 1 is provided with a fixing column 12 , and the fixing column 12 is clamped on the window mat 10 . Specifically, the fixing column 12 includes a first fixing column 121 connected to the spray pipe 1, and a second fixing column 122 integrally formed with the first fixing column 121, and the first fixing column 121 is in the The projection in the radial section of the second fixing column 122 is completely located in the radial section. A through hole is provided on the window mat 10 corresponding to the fixing column 12, the second fixing column 122 is arranged through the through hole and pressed against the outer wall of the window mat 10, the first fixing column 122 The outer wall of the column 121 is pressed against the inner wall of the through hole.

Due to the elasticity of the window mat 10, the second fixing column 122 can pass through the through hole under the action of a relatively large external force, and press against the outer wall of the window mat 10, and the second fixing column 122 can pass through the through hole. Afterwards, the window gasket 10 around the through hole recovers and deforms, so that the inner wall of the through hole is pressed against the outer wall of the first fixing post 121 , thereby realizing the fixing of the shower pipe 1 . The above-mentioned fixing method is simple, and can quickly realize the installation and disassembly of the spray device, and under the elastic deformation of the window mat 10, the inner wall of the through hole is pressed against the outer wall of the first fixing column 121, ensuring that the fixing column 12 and the window mat 10, the sealing effect at the connection position avoids water leakage at the connection position between the fixing column 12 and the window mat 10.

This embodiment also provides a drum washing machine, including the above-mentioned spraying device, and the spraying device is connected to a water inlet device of the drum washing machine through a pipeline.
