The barrier structure 51 is arranged around through-hole.It will be appreciated to those of skill in the art that between barrier structure 51 and hermetyic window pad 5 It can be connected together using any feasible mode, such as integrated injection molding, welding, ultrasonic bonding etc..

As shown in figure 9, barrier structure 51 is the bowl structure of a back-off, cavity is formed between hermetyic window pad 5 511, which is used to accommodate, wrap up the end of nozzle 12.Prevent user from launching clothing into inner cylinder 3 or inciting somebody to action from inner cylinder 3 When clothing takes out, clothing is caught in the end of nozzle 12.Further, it is additionally provided with out on barrier structure 51 towards the side of inner cylinder 3 Mouth 512, which is aligned with the jet port 123 (as shown in right figure 10) of nozzle 12, to guarantee that nozzle 12 can be by washing water Successfully in spirt inner cylinder 3.

As shown in Figure 10 to Figure 12, the nozzle 12 of the utility model mainly includes main body 121, is arranged in 121 one end of main body Occlusion part 122, the jet port 123 that is formed between main body 121 and occlusion part 122 and 121 other end of main body is set Interconnecting piece (does not indicate) in figure.Wherein, main body 121 is connected by interconnecting piece with annular chamber 11.Main body 121 is internally provided with The lower end (water inlet end) in channel 1211, the channel 1211 is connected to annular chamber 11, the upper end (water outlet) in the channel 1211 and spray Loophole 123 is connected to.It will be appreciated to those of skill in the art that can be using any feasible between main body 121 and occlusion part 122 Mode connect together, such as integrated injection molding, welding, ultrasonic bonding etc..Further, jet port 123 is in flat, So that nozzle 12 can spray fan-shaped washing water.

As shown in figure 11, the height of the lower wall (i.e. the upper end of main body 121) of jet port 123 sprays along jet port 123 The injection direction of washing water is gradually increased；Wherein, which is that the upper end of main body 121 reaches the distance of 121 lower end of main body.Injection The spray for the washing water that the height of the upper wall (i.e. occlusion part 122 is close to the side of main body 121) of mouth 123 sprays along jet port 123 Direction is penetrated to be gradually increased；Wherein, which is that the downside (lower end surface) of occlusion part 122 reaches the distance of 121 lower end of main body.

It is not difficult to find out that, the difference in height of the lower wall of jet port 123 is H from Figure 11.In the preferred implementation side of the utility model In case, the upper wall and lower wall of jet port 123 are substantially parallel, and therefore, the upper wall difference in height of jet port 123 is also H.With difference in height H is corresponding, and the upper wall of jet port 123 and the angle of horizontal direction are α.On the upper wall of jet port 123 and lower wall are arranged to The purpose for stating structure is, so that the injection direction of jet port 123 is directed toward the axis of inner cylinder 3, so that washing water can equably be fallen Enter in inner cylinder 3.Alternatively, those skilled in the art also can according to need, above-mentioned H and α are arranged to any feasible numerical value. For example, α is arranged to 0 ° or 90 °, even if the injection direction of jet port 123 and the axis direction of main body 121 are perpendicular or parallel.

It will be appreciated to those of skill in the art that the lower end surface of occlusion part 122 can be both obliquely installed such as above-mentioned, It can be vertically arranged relative to the axis direction of main body 121.Role is occlusion part 122 herein, and flows in channel 1211 Dynamic washing water collides, and washing water is broken up, and is in waterfall shape after spraying washing water from jet port 123.

As shown in figure 12, the junction of main body 121 and retaining section 122 forms the starting point (arc in Figure 12 of jet port 123 Dotted line), the height of the starting point is gradually increased along the circumferential direction of main body 121.Wherein, which is that starting point reaches main body The distance of 121 lower ends.

It is not difficult to find out that, the difference in height between the highest point and lowest part of the starting point is h from Figure 12.Wherein, which deposits Purpose be, so that horizontal direction in jet port 123 flat in Figure 12 and Figure 12 is formed angle β.In the utility model In preferred embodiment, 0 ° of 90 ° of < β <.

As shown in figure 13, when β=0 °, the plane that the position that the washing water that jet port 123 sprays falls is constituted is substantially It is upper vertical with axis (chain-dotted line in Figure 13) of inner cylinder 3.

As shown in figure 14, when 0 ° 90 ° of < β <, plane that the position fallen of washing water that jet port 123 sprays is constituted It is tilted with the axis (chain-dotted line in Figure 14) of inner cylinder 3.

Therefore, the fan-shaped washing water that the presence of angle β can be such that jet port 123 sprays is when falling into inner cylinder 3, in inner cylinder On 3 axis there is the vertical of L long to stretch covering.Wherein, L can be any feasible numerical value, such as 3cm, 4cm, 6cm etc..

In conclusion the roller washing machine of the utility model, which passes through, has been arranged equally spaced at hermetyic window pad 5 nozzle 12 On, the mounting structure of nozzle 12 is not only simplified, but also outer cylinder 2 is made to maintain original structure, reduces roller washing machine Production cost, while the washing water of annular spray as shown in Figure 1 can also be provided for the clothing in inner cylinder 3.Further, originally Utility model also by the way that the jet port 123 of nozzle 12 to be obliquely installed, makes jet port 123 have angle α and angle β, and then make Washing water can not only be sprayed in the axis of inner cylinder 3 by obtaining nozzle 12, additionally it is possible to keep washing water longitudinally covered interior along the axis of inner cylinder 3 Cylinder 3, sprays the clothing in inner cylinder 3 preferably, optimizes the washing effect of washing machine.

In the utility model in another feasible technical solution, those skilled in the art can also be as needed, will spray The setting of mouth 12 is in any feasible position.As example one, multiple nozzles 12 are arranged equally spaced to the edge of outer nozzle. As an example, multiple nozzles 12 are arranged equally spaced in door body 4.
