Description

TECHNICAL FIELD

[0001] The utility model relates to a washing machine technical field, especially in a kind of water-repellent rib with detachable filter screen structure and washing machine. BACKGROUND

[0002] In the course of laundry washing, clothes usually will drop cloth scraps, and the dropped cloth scraps will affect the washing effect of clothes if not handled, and it is easy to block the drainage pipeline when draining. In order to filter the cloth scraps dropped by clothes during washing, a lint collecting device is arranged in the inner barrel of the washing machine. When the lint collecting device needs to be cleaned, it usually needs to be disassembled as a whole, and then installed after cleaning. The operation is relatively cumbersome.

[0003] The patent with publication number CN110387662A discloses a pulsator and a washing machine. The pulsator includes a pulsator body, a water-repellent rib arranged on the top surface of the pulsator body, an annular fence extending downward from the back surface of the pulsator body to form a lint collecting cavity, and an opening and closing mechanism arranged in the lint collecting cavity. A plurality of through-flow holes are arranged on the water-repellent rib and communicate with the collecting cavity. A filter structure is arranged on the annular fence to block the passage of lint and allow the passage of water. The opening and closing mechanism is arranged to open the through-flow holes on the water-facing surface and close the through-flow holes on the water-backing surface with the rotation of the pulsator. The pulsator is installed in the washing drum, and a gap is arranged between the outer periphery of the pulsator and the washing drum, and the lint collecting cavity communicates with the drain port of the washing drum. During washing, the lint can be retained in the lint collecting cavity, realizing the collection of lint. When draining, the collected lint can be discharged from the drain port of the washing drum together with the water flowing into the lint collecting cavity, realizing automatic cleaning. The patent sets the lint collecting cavity on the lower side of the pulsator and corresponding through-flow holes on the water-repellent rib, so that the lint can enter the lint collecting cavity and be discharged with the water during washing. This setting requires the opening and closing mechanism to open or close the through-flow holes according to the direction of water flow, and the structure is relatively complex. Moreover, the lint collecting cavity cannot be completely cleaned of the cloth scraps through washing and draining, which can breed bacteria and pollute clothes. In addition, the cloth scraps in the lint collecting cavity usually form clumps, which can cause pipe blockage when discharged with the water, affecting the user experience. UTILITY MODEL CONTENTS

[0037] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] Embodiment 1

[0039] As shown in the drawings, the present application discloses a water-repellent rib with a detachable filter screen structure, comprising: Figures 1-8 The mounting seat 2 is fixedly arranged on the inner side wall of the washing tub of the washing machine;

[0040]

[0041] ​An outer shell 1 is connected with the mounting seat 2, and a water passing space is defined between the outer shell 1 and the mounting seat 2. A water inlet structure is arranged on the outer shell 1 and / or the mounting seat 2, and water in the washing tub can enter the water passing space through the water inlet structure. A filter screen 6 is arranged in the water passing space. A sliding cover 10 is arranged on a side of the outer shell 1 away from the inner side wall of the washing tub, and the sliding cover 10 is arranged in correspondence with the filter screen 6. The sliding cover 10 can be slid open to dismount and mount the filter screen 6.

[0042] Through the above arrangement, the water dispersing ribs and the filter screen 6 are integrated into an integral structure, so that the water dispersing ribs can filter the cloth scraps in the water while dispersing the water, and the cloth scraps are collected in the water passing space. When the cloth scraps need to be cleaned, the sliding cover 10 is slid open, the filter screen 6 is taken out, and after the filter screen 6 is cleaned, the filter screen 6 is mounted into the water passing space, and then the sliding cover 10 is closed. The structure is simple, and the operation is convenient. In the example, the filter screen 6 does not need to be arranged with a corresponding connecting structure, and can be directly placed in the water passing space. The operation is simple, and the user experience is significantly improved. As one of the preferred examples, a water drainage assembly is further arranged in the water passing space, and the water drainage assembly is used to drain the water filtered by the filter screen 6 out of the washing tub.

[0043] As one of the preferred examples, the filter screen 6 is a hexahedral structure, the middle part of which is hollow to form a scrap collecting groove. Five surfaces of the filter screen 6 are filter surfaces with gauze structures, and the other surface is an open surface. The open surface is arranged in correspondence with the water inlet structure. Specifically, when the filter screen 6 is arranged in the water passing space, the filter surfaces are arranged in correspondence with the corresponding inner walls or structures of the outer shell 1 and / or the mounting seat 2. Through the above arrangement, the filter screen 6 has a certain rigidity, so that the filter screen 6 is not deformed under the impact of the water flow, and the effect of filtering and collecting the cloth scraps is affected. The open surface is arranged in correspondence with the water inlet structure, so that the resistance is reduced, and the water flow is facilitated to enter the water dispersing ribs for filtering.

[0044] Optionally, a shielding part is arranged at the opening surface of the filter screen 6, which can open the opening surface under the action of centrifugal force when the washing tub rotates in a first direction, and can block the opening surface under the action of centrifugal force when the washing tub rotates in a second direction, the first direction being the rotation direction of the washing tub during dehydration or drainage, and the second direction being opposite to the first direction. Preferably, the shielding part is a flexible part made of flexible material such as rubber, one side of the shielding part is fixedly connected with the filter screen 6, and the other three sides are movable sides. When the washing tub rotates in the first direction, the shielding part is bent and deformed towards the inside of the debris collecting groove under the action of centrifugal force, so that the opening surface is opened, and the water during washing can be filtered. When the washing tub rotates in the second direction, the shielding part returns to the shielding state and is arranged in abutment with the inner wall of the shell 1 and / or the mounting seat 2, so as to block the opening surface, thereby preventing the lint collected in the debris collecting groove from flowing into the washing water again, and ensuring the collection and filtering effect of the filter screen 6 on the lint. As another optional example, the shielding part can also be made of hard material such as plastic, one side of the shielding part is rotatably connected with the filter screen 6. When the washing tub rotates in the first direction, the shielding part rotates towards the inside of the debris collecting groove under the action of centrifugal force, so that the opening surface is opened, and the water during washing can be filtered. When the washing tub rotates in the second direction, the shielding part rotates towards the opening surface and abuts against the inner wall of the shell 1 and / or the mounting seat 2, so as to block the opening surface, thereby preventing the lint collected in the debris collecting groove from flowing into the washing water again, and ensuring the collection and filtering effect of the filter screen 6 on the lint. It should be noted that the water inlet structure and the opening surface are arranged on one side of the water repelling rib, which faces the forward direction when the washing tub rotates in the first direction.

[0045] As another optional example, the water inlet structure includes a shell water inlet 101 and / or a mounting seat water inlet 201, the shell water inlet 101 is arranged on one side of the shell 1, and the mounting seat water inlet 201 is arranged on a corresponding side of the mounting seat 2. It should be noted that the side refers to a side on the shell 1 and / or the mounting seat 2, except for the two end faces in the length direction, the side close to the inner side wall of the washing tub, and the side away from the inner side wall of the washing tub, which is also the main side for water repelling. Through the above arrangement, during the laundry washing process and / or the drainage process, the water flow can enter the water passing space through the water inlet structure for filtering, thereby improving the lint filtering efficiency.

[0046] As one of the preferred examples, as shown in FIG. 1, Figure 1 , Figure 2As shown, the elastic locking structure is arranged between one end of the slide cover 10 and the shell 1, and can lock the slide cover 10 and the shell 1 together when the slide cover 10 is closed. Through the arrangement of the elastic locking structure, the slide cover 10 can be locked with the shell 1 when it is closed, avoiding opening during the working process of the washing tub, thereby effectively preventing the filtered cloth scraps in the filter screen 6 from entering the washing space again, and ensuring the washing effect of the clothes. In addition, the elastic locking structure can be unlocked under the action of external force, thereby facilitating the opening of the slide cover 10. Specifically, when the filter screen 6 needs to be taken out, press the end of the slide cover 10 close to the elastic locking structure, so that the elastic locking structure deforms to a certain extent and is unlocked, and the filter screen 6 can be conveniently and quickly taken out.

[0047] Specifically, the elastic locking structure includes an elastic lock hook 1011 and an elastic lock buckle 102, which can be locked together and can be elastically deformed to be unlocked under the action of external force. The elastic lock hook 1011 is arranged on the slide cover 10 or the shell 1, and the elastic lock buckle 102 is correspondingly arranged on the shell 1 or the slide cover 10.

[0048] As one of the preferred examples, a guide groove 103 is arranged on the shell 1, and a guide rail 1012 is correspondingly arranged on the slide cover 10. The guide rail 1012 and the guide groove 103 are arranged in cooperation, so that the slide cover 10 can move along the guide groove 103. Specifically, the guide groove 103 and the guide rail 1012 are connected in cooperation through concave-convex structure or I-shaped structure or other structures that can realize guiding sliding, which will not be limited here. Through the above arrangement, the moving direction of the slide cover 10 can be guided, so that the slide cover 10 can be well opened or closed with the shell 1.

[0049] As one of the preferred examples, a drainage through hole is arranged on the mounting seat 2, and a drainage port is correspondingly arranged on the washing tub. The drainage through hole and the drainage port cooperate to form a drainage passage, and a centrifugal valve group is arranged on the drainage through hole. The centrifugal valve group can block the drainage passage when the washing tub is stationary or rotates at low speed, and can open the drainage passage under the action of centrifugal force when the washing tub rotates at high speed.

[0050] It should be understood that in the present example, the drainage through hole and the centrifugal valve group form a drainage assembly. By the above arrangement, the washing tub can be provided as a non-porous inner tub, which is provided with no holes except the drainage port. By the arrangement of the centrifugal valve group, the drainage passage is blocked when the non-porous inner tub is at rest or rotates at a low speed, so as to avoid the outflow of washing water, ensure the normal operation of the washing condition, and effectively avoid the washing water entering between the outer tub and the inner tub, avoid the secondary pollution caused by the interaction of washing water between the inner tub and the outer tub during the washing process, and ensure the washing effect of the clothes. When the non-porous inner tub rotates at a high speed, it is usually in a drainage or dehydration condition. At this time, the centrifugal valve group is connected under the action of centrifugal force or inertial force, so as to drain the washing water in the non-porous inner tub outside the tub, and realize the smooth drainage of the non-porous inner tub. It should be noted that the low speed rotation refers to the rotation speed of the non-porous inner tub in the washing condition, which is usually lower than 150 r / min, and the high speed rotation refers to the rotation speed of the non-porous inner tub in the drainage or dehydration condition, which is usually higher than 150 r / min. It should be noted that the low speed rotation and the high speed rotation in the present application can be set by a preset rotation speed. When the rotation speed of the non-porous inner tub is lower than a first preset rotation speed, it is a low speed rotation, and the washing machine is in a water inlet condition, a washing condition, or a rinsing condition. When the rotation speed is higher than a second preset rotation speed, it is a high speed rotation, and the washing machine is in a dehydration condition or a drainage condition. The first preset rotation speed is lower than the second preset rotation speed, and preferably, the first preset rotation speed is between 100 and 150 r / min, and the second preset rotation speed is between 150 and 200 r / min. The specific value can be determined according to the specifications and models of the washing machine, and will not be limited here. In addition, a third preset rotation speed can also be set according to the requirements. The third preset rotation speed is higher than the second preset rotation speed. When the rotation speed of the washing tub reaches the third preset rotation speed or above, the centrifugal valve group is completely opened, so as to facilitate the smooth progress of the dehydration or drainage process. In one example, when the washing tub does not rotate or the rotation speed of the washing tub is lower than 150 r / min, the centrifugal valve group is in a closed state. When the washing tub needs to be dehydrated or drained, the rotation speed reaches 200 r / min or above, the centrifugal valve group is gradually opened, and the drainage passage is gradually connected. When the rotation speed reaches 300 r / min or above, the centrifugal valve group is completely opened, so as to realize the drainage or dehydration of the washing tub. In the present example, the first preset rotation speed is 150 r / min, the second preset rotation speed is 200 r / min, and the third preset rotation speed is 300 r / min. It should be noted that the centrifugal valve group includes a centrifugal valve 4 and / or a duckbill check valve 3.

[0051] As one of the preferred examples, the water passing space includes a first space and a second space, the sliding cover 10 is arranged corresponding to the first space, a plurality of support columns 104 are arranged between the first space and the second space, the filter screen 6 is arranged in the first space, one of the filter surfaces of the filter screen 6 abuts against the support column 104, and the centrifugal valve group is arranged on the mounting seat 2 corresponding to the first space and / or the second space. Preferably, the first space and the second space are arranged along the length direction of the waterway, and the sliding cover 10 slides to open or close along the length direction of the waterway. Through the above arrangement, the sliding cover 10 is located outside the second space when being opened, which can be outside or inside the shell 1 corresponding to the second space, and preferably inside. In this case, the moving stroke of the sliding cover 10 when being opened is entirely located in the waterway, and interference with other components does not need to be considered. Preferably, the outer side surface of the sliding cover 10 is arranged in abutment with the inner side surface of the shell 1 corresponding to the second space. This arrangement can effectively prevent washing water from entering the waterway through the gap between the sliding cover 10 and the shell 1, and then entering the second space without being filtered, thereby ensuring that all the water in the washing tub passes through the water inlet structure into the waterway, and then enters the drainage passage after being filtered. Preferably, the centrifugal valve group is arranged on at least the mounting seat 2 corresponding to the second space. It should be understood that, due to the interval arrangement of the support columns 104, the first space and the second space are communicated through the gaps between the support columns 104. The water filtered by the filter screen 6 in the first space can enter the second space through the gaps, and then be discharged through the centrifugal valve group, thereby ensuring that all the water discharged through the centrifugal valve group is filtered, and avoiding the risk of clogging the pipeline due to the discharge of cloth scraps with the water.

[0052] As one of the optional examples, as shown in Figures 2-7 The centrifugal valve group includes a duckbill check valve 3, the drainage passage hole includes a second drainage hole arranged on the mounting seat 2 corresponding to the first space, and the duckbill check valve 3 is arranged at the second drainage hole and can be opened to guide the second drainage hole and the drainage port in communication when the washing tub rotates at a high speed. Through the above arrangement, the duckbill check valve 3 is in a closed state when the washing tub rotates at a low speed, which can prevent the water in the washing tub from entering between the outer tub and the inner tub. When rotating at a high speed, the duckbill check valve 3 is opened to guide the second drainage hole and the drainage port in communication, which facilitates the discharge of the water in the washing tub. It should be noted that the opening pressure of the duckbill check valve 5 which is opened or closed under different rotating speeds according to different models can be adjusted by adjusting one or more parameters such as the material, hardness, length and width of the duckbill, and the thickness of the duckbill valve tongue of the raw rubber of the duckbill check valve 5. The specific adjustment mode can refer to the prior art, which is not limited here.

[0053] As one of the examples, as shown in Figure 8 The duckbill check valve 3 includes a mounting portion 301 fixedly mounted on the circumference of the second drain hole and first and second valve flaps 302, 303 sealingly abutting in a normal state, and under a high-speed rotating state of the washing tub, the first and second valve flaps 302, 303 are separated from each other under the action of centrifugal force and water pressure, so that the second drain hole is communicated with the drain port. It should be noted that when the washing tub rotates at a low speed, the centrifugal force and water pressure borne by the first and second valve flaps 302, 303 are not enough to separate them, so that they can be kept in a sealing state to prevent water in the washing tub from flowing out, and when the washing tub rotates at a high speed, the first and second valve flaps 302, 303 gradually move away from each other, so that water in the washing tub can be drained.

[0054] As another optional example, as shown in Figure 2 The centrifugal valve group includes a centrifugal valve 4 arranged in the second space, the drain through hole includes a first drain hole arranged on the mounting seat 2 corresponding to the second space, and the centrifugal valve 4 is arranged in cooperation with the first drain hole and can communicate the first drain hole with the drain port when the washing tub rotates at a high speed. It should be understood that the distance between the inner tub and the outer tub in the washing machine is small, the valve flaps of the duckbill check valve 3 are relatively long, and are easy to contact or interfere with the outer tub, affecting the plugging effect and the drainage effect. In order to avoid the contact or interference between the duckbill check valve 3 and the outer tub, the duckbill check valve 3 is moved towards the center of the inner tub in the specific arrangement, which makes the side of the duckbill check valve 3 close to the inner tub protrude relative to the mounting seat 2. In this case, the separately arranged duckbill check valve 3 will have a part of water unable to drain out of the tub, affecting the drainage effect of the inner tub. Therefore, the corresponding centrifugal valve 4 needs to be arranged to ensure that the water in the inner tub is drained, so as to improve the user experience. In addition, if the centrifugal valve 4 is arranged separately, it occupies a large space due to its structure similar to a seesaw, and a corresponding filtering structure cannot be arranged, so that the cloth scraps in the water cannot be removed, affecting the user experience. Since the duckbill check valve 3 occupies a small space, a filtering structure can be conveniently arranged at the position of the duckbill check valve 3, therefore, the duckbill check valve 3 and the centrifugal valve 4 are arranged on the water deflector at the same time, which can not only ensure that the water in the inner tub is drained, but also can set a filter screen to filter the cloth scraps in the water, significantly improving the user experience.

[0055] As one of the preferred examples, one or more of the first drain holes are provided on the mounting seat 2, and / or one or more of the second drain holes are provided on the mounting seat 2, the number of the centrifugal valve 4 is correspondingly provided with the number of the first drain holes, and the number of the duckbill check valve 3 is correspondingly provided with the number of the second drain holes. Through the above arrangement, the number of the first drain holes, the centrifugal valve 4, the second drain holes, and the duckbill check valve 3 can be set according to the specific model of the washing machine, so as to ensure the drainage efficiency of the washing machine.

[0056] As an example of the present application, the diameter of the first drain hole is larger than the diameter of the second drain hole. Through the above arrangement, the drainage capacity of the first drain hole can be significantly improved, so as to facilitate the rapid emptying of the water in the non-porous inner drum and improve the drainage efficiency.

[0057] As one of the examples, as shown in Figure 2 The centrifugal valve 4 includes a counterweight part 401, a rotating shaft part 402, a torsional spring 403, and a sealing part 404. The centrifugal valve 4 is locked or rotated relative to the mounting seat 2 through the rotating shaft part 402 and the torsional spring 403. The counterweight part 401 and the sealing part 404 are respectively arranged on the opposite sides of the rotating shaft part 402. When the washing drum is stationary or rotates at a low speed, the sealing part 404 is in sealing contact with the first drain hole under the action of the torsional spring 403. When the washing drum rotates at a high speed, the counterweight part 401 of the centrifugal valve 4 rotates against the force of the torsional spring 403 under the action of centrifugal force, and then the sealing part 404 is separated from the first drain hole. It should be noted that through the above structure, the centrifugal valve 4 forms a structure similar to a seesaw around the rotating shaft part 402. When the washing drum is stationary or rotates at a low speed, the pre-tightening force of the torsional spring 403 applied to the counterweight part 401 keeps it away from the mounting seat 2, and correspondingly, the sealing part 404 keeps close to the mounting seat 2, so as to block the first drain hole. When the washing drum rotates at a high speed, the counterweight part 401 moves towards the mounting seat 2 against the pre-tightening force of the torsional spring 403 under the action of centrifugal force or inertial force. At this time, the sealing part 404 moves away from the mounting seat 2 around the rotating shaft part 402, so that the sealing part 404 is separated from the first drain hole, and the water in the washing drum is easily drained. Figure 2 As shown in Figure 2 In order to ensure that the auxiliary counterweight part 401 overcomes the force of the torsional spring 403 under the action of centrifugal force, a counterweight block 405 is arranged on the counterweight part 401. It should be noted that the length of the counterweight part 401 and the sealing part 404, the mass of the counterweight block 405, and the related parameters of the torsional spring 403 can be obtained by calculation, and the related calculation method belongs to the prior art, which is not limited here.

[0058] As one of the preferred examples, as shown in Figure 4 , Figure 7 The sealing ring 5 is sleeved on the circumference of the first drain hole, and the sealing part 404 cooperates with the sealing ring 5 to form a seal when the washing tub is at rest or low speed rotation. Specifically, when the washing tub is at rest or low speed rotation, the sealing part 404 of the centrifugal valve 4 cooperates with the sealing ring 5 to form a seal under the action of the torsional spring 403, thereby plugging the first drain hole, which can effectively prevent washing water from entering between the outer tub and the inner tub. When the washing tub is at high speed rotation, the counterweight part 401 of the centrifugal valve 4 moves towards the mounting seat 2 under the action of centrifugal force or inertial force, overcoming the force exerted by the torsional spring 403, driving the sealing part 404 to move away from the mounting seat 2, and further causing the sealing part 404 to disengage from the sealing ring 5, so that the first drain hole is in communication with the drain port, thereby draining the water in the washing tub.

[0059] The duckbill check valve 3 and the centrifugal valve 4 in the water diversion rib described in the present application are both opened at high speed rotation in the washing tub 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.

[0060] Specifically, the working principle of the water diversion rib is as follows:

[0061] When the washing tub is not rotating or the rotating speed is lower than the first preset rotating speed (150 r / min, i.e. the washing state), the duckbill check valve 3 and the centrifugal valve 4 are both in a closed state, respectively plugging the first drain hole and the second drain hole. At this time, water entering the water diversion rib will not be drained out of the tub, nor will it enter between the inner tub and the outer tub, but will only circulate in the washing tub, avoiding secondary pollution of the clothes. When drainage or dehydration is needed, the rotating speed of the washing tub rises, and when it rises above the second preset rotating speed (200 r / min), the duckbill check valve 3 and the centrifugal valve 4 gradually open, the first drain hole and the second drain hole are respectively in communication with the drain port, and the water in the washing tub is gradually drained out. When the rotating speed of the washing tub reaches above the third preset rotating speed (300 r / min), the duckbill check valve 3 and the centrifugal valve 4 are completely opened, which can drain water at the maximum speed. The washing tub is a non-porous inner tub, and all the water needs to be drained through the duckbill check valve 3 and the centrifugal valve 4. In this case, the drained water needs to be filtered through the filter screen 6 before it can be drained, which can effectively filter the lint in the water. Preferably, during the drainage process, the rotating speed of the washing tub is lower than the third preset rotating speed, and when most of the water in the washing tub is drained out of the washing tub (which can be judged according to the water level or other means, which is not limited here), the rotating speed of the washing tub is increased for high-speed dehydration. This setting can avoid high-speed dehydration of the washing tub under heavy load, preventing mechanical wear and tear.

[0062] When the filter screen 6 needs to be cleaned, the slide cover 10 is pushed by hand to the end close to the elastic lock hook 1011 and pushed away from the elastic lock catch 102, so that the elastic lock hook 1011 is separated from the elastic lock catch 102, and then the slide cover 10 is continuously pushed to move until the filter screen 6 can be taken out of the water passing space, and the filter screen 6 is taken out for manual cleaning, and after cleaning, the filter screen 6 is placed into the water passing space, the slide cover 10 is pushed to move to the direction of the elastic lock catch 102 until the two are locked, and the disassembly, cleaning and installation of the filter screen 6 are completed.

[0063] It should be noted that the water-repellent ribs provided in the example are fixed on the inner side wall of the washing tub, and the number is more than one, and the fixing mode can adopt any one of the following implementation modes, such as bolt connection, concave-convex cooperation, clamping, third connecting piece fixing, etc., and will not be limited here.
