[0048] The utility model discloses below will refer to the drawing and combine the embodiment to explain in detail.

[0049] Embodiment 1

[0050] As Figures 1-20 The utility model discloses a kind of washing-free non-hole inner bucket drainage switch, comprising:

[0051] Base 1, the base 1 is arranged on non-hole inner bucket side wall, drainage through-hole is provided on base 1, drainage port is provided on non-hole inner bucket, the drainage through-hole is correspondingly arranged with drainage port, for cooperation form the drainage passage of non-hole inner bucket, centrifugal valve group is provided on the drainage through-hole, the centrifugal valve group can be blocked when non-hole inner bucket is stationary or low-speed rotation Drainage passage, under the action of centrifugal force when non-hole inner bucket high-speed rotation Drainage passage is conducted.

[0052] It needs to be explained that low-speed rotation refers to the rotational speed of non-hole inner bucket under washing condition, usually below 150r / min, high-speed rotation refers to the rotational speed of non-hole inner bucket under drainage or dewatering condition, usually above 150r / min, it needs to be explained that low-speed rotation and high-speed rotation in the application can be set by preset rotational speed, when the rotational speed of non-hole inner bucket is below first preset rotational speed, it is low-speed rotation, washing machine is under water inlet condition, washing condition, rinsing condition, when the rotational speed is above second preset rotational speed, it is high-speed rotation, washing machine is under dewatering condition or drainage condition, first preset rotational speed is less than second preset rotational speed, preferably, the first preset rotational speed is between 100~150r / min, and the second preset rotational speed is between 150~200r / min, and specifically, it can be determined according to the specification and model of washing machine, which will not be limited here. In the example, by the arrangement of centrifugal valve group, when non-hole inner bucket is stationary or low-speed rotation, drainage passage can be blocked, to avoid washing water outflow, ensure normal operation of washing condition, also effectively avoid washing water into between outer barrel and inner barrel;When non-hole inner barrel high-speed rotation, it is usually under drainage or dewatering condition, at this time, centrifugal valve group under the action of centrifugal force or inertial force Drainage passage is conducted, so that washing water in non-hole inner barrel is discharged outside the barrel, realizes the smooth drainage of non-hole inner barrel. The application can ensure the normal operation of washing machine washing condition, drainage condition, dewatering condition by the arrangement of centrifugal valve group, avoid secondary pollution produced by washing water interaction between inner barrel and outer barrel during washing process, ensure the cleaning effect of clothes washing. It needs to be explained that the centrifugal valve group includes centrifugal valve 6 and / or duckbill valve 5. In the example, the non-hole inner barrel is only provided with drainage port at the position corresponding to drainage switch, and the rest positions are non-hole structure.

[0053] As one of the optional examples, Figure 2 , Figure 3 ,Figure 5 , Figure 10 , Figure 11 , Figure 13 As shown, the centrifugal valve assembly includes a duckbill valve 5, and the drain passage includes a second drain hole 4. The duckbill valve 5 is located at the second drain hole 4. The duckbill valve 5 can open when the non-perforated inner tub rotates at high speed, connecting the second drain hole 4 with the drain outlet. With this configuration, when the non-perforated inner tub rotates at low speed, the duckbill valve 5 is in a closed state, preventing water from the non-perforated inner tub from entering between the outer and inner tubs. When rotating at high speed, the duckbill valve 5 opens, connecting the second drain hole 4 with the drain outlet, facilitating the discharge of water from the non-perforated inner tub. It should be noted that the opening pressure of the duckbill valve 5, which is set to open or close under different speed conditions according to different models and specifications, can be adjusted by adjusting the material of the duckbill valve 5 or by setting a frame or other structures within it. Specific adjustment methods can be found in existing technologies and will not be elaborated here.

[0054] As one example, such as Figures 18-20 As shown, the duckbill valve 5 includes a mounting part 501 and a first valve tongue 502 and a second valve tongue 503. The mounting part 501 is fixedly installed on the circumference of the second drain hole 4. Under normal conditions, the first valve tongue 502 and the second valve tongue 503 are sealed together. When the non-perforated inner tub rotates at high speed, the first valve tongue 502 and the second valve tongue 503 move away from each other under the action of centrifugal force and water pressure, so that the second drain hole 4 is connected to the drain outlet. Here, "normal condition" refers to the state when the non-perforated inner tub is stationary or rotating at low speed. It should be noted that when the non-perforated inner tub rotates at low speed, the centrifugal force and water pressure on the first valve tongue 502 and the second valve tongue 503 are insufficient to separate them, so that they can remain in a sealed state to prevent water from flowing out of the non-perforated inner tub. When the non-perforated inner tub rotates at high speed, the first valve tongue 502 and the second valve tongue 503 gradually move away from each other, so that water in the non-perforated inner tub can be discharged.

[0055] As another optional example, such as Figures 2-4 , Figures 10-12As shown, the centrifugal valve group includes a centrifugal valve 6, the drain through hole includes a first drain hole 3, the centrifugal valve 6 is arranged at the first drain hole 3, and the centrifugal valve 6 can guide the first drain hole 3 to the drain port when the inner pot rotates at high speed. It should be understood that the distance between the inner pot and the outer pot of the washing machine is small, the valve tongue of the duckbill valve 5 is relatively long, and is easy to contact or interfere with the outer pot, affecting the sealing effect and the drainage effect. In order to avoid the contact or interference between the duckbill valve 5 and the outer pot, the duckbill valve 5 is moved towards the center of the inner pot during specific arrangement. The setting makes the side of the duckbill valve 5 close to the inner pot protrude relative to the base 1. In this case, a part of the water cannot be drained out of the pot when the duckbill valve 5 is arranged alone, affecting the drainage effect of the inner pot. Therefore, the corresponding centrifugal valve 6 needs to be arranged to ensure that the water in the inner pot is drained, so as to improve the user experience. In addition, if the centrifugal valve 6 is arranged alone, the space occupied by the structure similar to the seesaw is large, and the corresponding filter structure cannot be arranged, the cloth scraps in the water cannot be removed, and the user experience is affected. Since the duckbill valve 5 occupies a small space, the filter structure can be arranged at the position of the duckbill valve 5. Therefore, the duckbill valve 5 and the centrifugal valve 6 are arranged on the drain switch at the same time, which can ensure that the water in the inner pot is drained, and the filter screen can be arranged to filter the cloth scraps in the water, which significantly improves the user experience.

[0056] As one of the preferred examples, one or more of the first drain holes 3 are arranged on the base 1, and / or one or more of the second drain holes 4 are arranged on the base 1. The number of centrifugal valves 6 corresponds to the number of first drain holes 3, and the number of duckbill valves 5 corresponds to the number of second drain holes 4. Through this setting, the number of first drain holes 3, centrifugal valves 6, second drain holes 4, and duckbill valves 5 can be set according to the specific model and specifications of the washing machine, so as to ensure the drainage efficiency of the washing machine.

[0057] As one of the examples, as shown in FIG. 1, the first drain hole 3 is arranged on the base 1, and the centrifugal valve 6 is arranged at the first drain hole 3. The second drain hole 4 is arranged on the base 1, and the duckbill valve 5 is arranged at the second drain hole 4. Figures 6-9As shown, the centrifugal valve 6 includes a counterweight part 601, a rotating shaft part 602, a torsion spring 603, and a sealing part 604. The centrifugal valve 6 is locked or rotated relative to the base 1 through the rotating shaft part 602 and the torsion spring 603. The counterweight part 601 and the sealing part 604 are respectively arranged on opposite sides of the rotating shaft part 602. When the inner basket is at rest or rotates at a low speed, the sealing part 604 is in sealing contact with the first drain hole 3 under the action of the torsion spring 603. When the inner basket rotates at a high speed, the counterweight part 601 of the centrifugal valve 6 rotates against the action of the torsion spring 603 under the action of centrifugal force, and then separates the sealing part 604 from the first drain hole 3. It should be noted that, through the above structure, the centrifugal valve 6 forms a structure similar to a seesaw around the rotating shaft part 602. When the inner basket is at rest or rotates at a low speed, the force applied by the torsion spring 603 to the counterweight part 601 keeps the counterweight part 601 away from the base 1, and correspondingly, the sealing part 604 keeps close to the base 1, so as to block the first drain hole 3. When the inner basket rotates at a high speed, the counterweight part 601 moves towards the base 1 under the action of centrifugal force or inertial force. At this time, the sealing part 604 moves away from the base 1 around the rotating shaft part 602, so that the sealing part 604 is separated from the first drain hole 3, and water in the inner basket is easily drained.

[0058] As one of the preferred examples, as shown in the drawings, Figure 8 As shown, a sealing plug 605 is arranged on the side of the sealing part 604 close to the first drain hole 3, and the sealing plug 605 can extend into the first drain hole 3 to form a seal. Specifically, when the inner basket is at rest or rotates at a low speed, the sealing plug 605 of the centrifugal valve 6 extends into the first drain hole 3 to form a seal under the action of the torsion spring 603, which can effectively prevent washing water from entering between the outer basket and the inner basket. When the inner basket rotates at a high speed, the counterweight part 601 of the centrifugal valve 6 moves towards the base 1 against the action of the torsion spring 603 under the action of centrifugal force or inertial force, drives the sealing part 604 to move away from the base 1, and then makes the sealing plug 605 separate from the first drain hole 3, so that the first drain hole 3 is communicated with the drain port, and water in the inner basket is drained.

[0059] Optionally, in order to ensure that the auxiliary counterweight part 601 overcomes the action of the torsion spring 603 under the action of centrifugal force, a counterweight block (not shown in the drawings) is arranged on the counterweight part 601. It should be noted that the length of the counterweight part 601 and the sealing part 604 on the centrifugal valve 6, the mass of the counterweight block, and the related parameters of the torsion spring 603 can be obtained by calculation, and the related calculation method belongs to the prior art, which is not limited here.

[0060] The duckbill valve 5 and the centrifugal valve 6 in the drain switch described in the present application are opened when rotating at high speed in the non-porous inner drum dehydration and drainage working condition, and are kept closed in the non-dehydration and drainage working condition, thereby ensuring the normal operation of each working condition in the clothes washing process.

[0061] As a preferred example of the present application, the drain switch described in the present application can be designed separately on the non-porous inner drum, and a streamlined structure or an arc-shaped structure is arranged on the base 1 to prevent the clothes from being hung on the wall during washing or rinsing or dehydration working condition, thereby preventing the clothes from being damaged.

[0062] As a preferred example of the present application, the drain switch described in the present application can be arranged as a water-repellent rib on the non-porous inner drum. In this design concept, as shown in Figures 14-17 , a detachable shell 2 is arranged on the base 1, a water inlet hole 7 is arranged on the shell 2, and a water inlet cavity is formed between the shell 2 and the base 1. The water in the water inlet cavity is discharged when the duckbill valve 5 and / or the centrifugal valve 6 are opened by the centrifugal force in the dehydration and drainage working condition. Through the above arrangement, the drain switch can be combined with the shell 2 to form a water-repellent rib, and the original structure of the inner drum is used for drainage, thereby reducing the number of components on the side wall of the non-porous inner drum, reducing the risk of clothes hanging on the wall, and improving the effect of clothes washing.

[0063] As a preferred example, a filter structure is arranged in the water inlet cavity, the filter structure is arranged opposite to the water inlet hole 7, and the water filtered through the filter structure is discharged through the duckbill valve 5 and / or the centrifugal valve 6. The filter structure can effectively filter the cloth scraps in the water, thereby avoiding the cloth scraps entering the drainage pipeline during drainage, and reducing the risk of cloth scraps blocking the pipeline.

[0064] It should be understood that the shell 2 and the base 1 can be connected by any one of the following connection modes, such as bolt connection, concave-convex matching, clamping, third connecting piece fixing, etc., and will not be limited here.

[0065] As a specific example of the present application, as shown in Figure 3 , Figure 15 , the shell 2 and the base 1 are limited by the concave-convex matching of the plug-in block 9 at one end, and are locked by the lock catch 8 and the structure on the inner wall of the non-porous inner drum or the base 1 at the other end. During use, the end of the shell 2 is separated from the non-porous inner drum or the base 1 by pressing the lock catch 8, and the plug-in block 9 at the other end is pulled to one side to be taken out. The structure is simple and convenient to disassemble and assemble. Specifically, a plug-in part is arranged on the base 1 near the plug-in block 9, the plug-in part is matched with the plug-in block 9 to limit, and a lock block is arranged on the base 1 near the lock catch 8 or on the inner wall of the non-porous inner drum relative to the position of the lock catch 8. The lock block can be locked with the lock hook on the lock catch 8.

[0066] As an example of the present application, the first drain hole 3 has a larger hole diameter than the second drain hole 4. With the above arrangement, the water draining capacity of the first drain hole 3 can be significantly improved, thereby facilitating the rapid emptying of water in the hole-free inner tub and improving the water draining efficiency.

The drain switch and the hole-free inner tub can be connected by any one of the following connection modes, such as bolt connection, concave-convex matching, clamping, third connecting piece fixing, etc., and are not limited herein.

[0070] The above only describes the preferred embodiments of the present application and is not intended to limit the present application.
