In order to improve the clothes wetting degree close to the rear flange of the inner barrel in the prior art, a sprayer is arranged on the rear flange of the inner barrel and can spray clothes close to the rear flange.

Because the washing cylinders with different volumes often have different spraying mileage and spraying angles to the sprayer, the washing cylinders with different volumes can be provided with the sprayers with different sizes, but the sprayers have the same shape, and the sprayers with the same type cannot be applied to different machine types. Therefore, in the manufacturing process, the mold needs to be redesigned for sprinklers with different sizes, and the design period of the mold is long, which directly results in the increase of the time to market of new products and the development cost of the mold. Meanwhile, different users have different requirements on the sprayer, and for the customized washing machine, the existing sprayer is poor in universality, so that the cost of the customized washing machine is increased.

Therefore, a need exists for a sprayer that can solve the problem of poor versatility of prior art sprayers.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.

The embodiment provides the sprayer which can be suitable for washing machines of different types and different capacities, is higher in universality and saves research and development cost.

As shown in fig. 1 and 3, it is a schematic structural diagram of the sprayer; the sprayer 2 comprises a spray frame 21 and a spray head 22 arranged on the spray frame 21, wherein at least two groups of spray holes 221 are arranged on the spray head 22, the central axes of the spray holes 221 in the same group are arranged in parallel or in a crossed manner, and when the central axes of the spray holes 221 in the same group are parallel, the central axes of the spray holes 221 in different groups have different inclination angles relative to the central axis of the spray head 22. The spray frame 21 is provided with a water outlet 2121, the water outlet 2121 can be selectively communicated with one group of the spray holes 221, and the other spray holes 221 are not communicated with the water outlet 2121. The shower 2 in this embodiment is installed outside the inner cylinder body 1.

Of course, in other embodiments, when the sprayer 2 is located inside the inner cylinder body 1, the number of the groups of the spray holes 221 on the spray frame 21 may be set according to the number of the spray holes 2121, that is, the number of the groups of the spray holes 221 is the same as the number of the water outlet holes 2121, or the number of the groups of the spray holes 221 is smaller than the number of the water outlet holes 2121.

It should be noted that, in order to have different numbers of the spraying holes 221 in each group for the inner cylinder bodies 1 having different volumes, in this case, when the shower head 22 is installed, the spraying holes 221 can be selected according to the volume of the inner cylinder body 1, a group having a larger volume of the spraying holes 221 is selected for the inner cylinder body 1, and a group having a smaller volume of the spraying holes 221 is selected for the inner cylinder body 1.

As shown in fig. 2 and 3, they are schematic structural views of the nozzle 22. In this embodiment, the nozzle 22 has a hexagonal prism structure, the spraying holes 221 are disposed on the sidewall of the nozzle 22, and the sidewall with the spraying holes 221 is disposed at intervals. The spray head 22 is connected with the bracket 212 of the spray frame 21 in an interference fit manner or in a threaded manner. In this embodiment, the bracket 212 of the spray frame 21 is a cylindrical structure, the nozzle 22 is provided with a first connection hole 222 and a water containing hole 223 communicated with the first connection hole 222 along the axial direction thereof, water sprayed from the spray frame enters the water outlet hole 2121 through the water containing hole 223 to be sprayed, wherein the diameter of the first connection hole 222 is larger than that of the water containing hole 223, and the water containing hole 223 is communicated with the water outlet hole 2121. Three groups of spraying holes are arranged on the spray head 22, and the number of the spraying holes in each group is different.

Taking the spray head 22 as a hexagonal prism structure as an example, the spray holes 221 have four forms, the first is that the inclination angles of the same group of spray holes 221 relative to the side wall where the group of spray holes 221 are located are different, the arrangement mode can ensure that the clothes in the inner cylinder are soaked and the foam can be eliminated more, and ensure that the water flow in different directions is sprayed at the rear flange of the inner cylinder body 1; the second is that the inclination angles of the same group of spray holes 221 relative to the side wall where the group of spray holes 221 are located are the same; the third is that the inclination angles of the partial spray holes 221 in the same group of spray holes 221 are the same as the inclination angle of the side wall where the group of spray holes 221 are located, and the other inclination angles are different from the horizontal plane, and the arrangement mode can also wet clothes in a large area, so that more foams are eliminated; the fourth concrete is that in the same group of spraying holes 221, the symmetrically arranged spraying holes 221 have the same inclination angle with respect to the side wall where the group of spraying holes 221 are located, and the spraying holes 221 located in the middle are vertically arranged with respect to the side wall where the group of spraying holes are located. The same group of spray holes in this embodiment refer to the spray holes arranged in a straight line along the axial direction of the nozzle 22.

Fig. 4 is a schematic structural view of the sprayer with a spray head 22 hidden. This spray frame 21 is including the support body 211 that is cylindrical structure and a plurality of support 212 of setting on support body 211, and support 212 quantity is three, and three support 212 circumference equipartition is on the lateral wall of support body 211, and every support 212 all communicates with support body 211 and guarantees that water can get into in the support 212 from support body 211. Wherein the spray frame 21 is in threaded connection with one end of the inner cylinder shaft 3, specifically, an external thread is arranged on the frame body 211, and an internal thread and an external thread are arranged on the hole wall of the water inlet through hole 31 of the inner cylinder shaft 3. Wherein the water inlet through hole 31 communicates with the holder body 211. The water outlet 2121 is disposed on the bracket 212, and a first groove 2122 is further disposed outside the water outlet 2121, and a third sealing ring (not shown) is disposed in the first groove 2122 to seal the space between the bracket 212 and the nozzle 22, thereby preventing water leakage.

More specifically, a connection stage 23 protrudes from one side of the frame body 211 connected to the inner cylinder shaft 3, and the connection stage 23 includes a connection column 231 provided with an external thread and a tapered stage 232 extending into the inner cylinder shaft 3. This toper platform 232 can be comparatively easy stretch into in the through-hole 31 of intaking of inner tube axle 3, makes support body 211 and inner tube axle 3 high-speed joint. In order to prevent water leakage at the joint of the holder body 211 and the inner cylinder shaft 3, a first sealing ring 7 is further disposed between the tapered platform 232 and the inner cylinder shaft 3, and in the embodiment, a second groove for accommodating the first sealing ring 7 is disposed in the circumferential direction of the tapered platform 232.
