[0002] Taking a top-loading washing machine as an example, during the washing process, the washing drum rotates, for example, at a speed of 18 to 210 revolutions per minute. Under the action of centrifugal force, the water in the water tank will rotate and climb up along the wall of the water tank. When it climbs to the water tank lid, the water tank lid will block the rising water flow and prevent the water flow from climbing further up and causing it to overflow the water tank.

[0003] The water jet from the inner edge of the bucket lid sprays onto the clothes, but the coverage area is relatively small. Summary of the Invention

[0065] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0066] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] This application provides an inner cover device 10 for a washing device.

[0068] Please see Figure 15 and Figure 17The inner cover device 10 includes an inner cover 11 and a waterfall cover 12.

[0069] The waterfall cover 12 is located below the inner cover 11 and can rotate relative to the inner cover 11. A gap space is formed between the waterfall cover 12 and the inner cover 11. The outer circumferential side of the gap space is open to form an annular inlet 10a for receiving water flow.

[0070] Please see Figure 18 The waterfall cover 12 is provided with water outlet channels 12c' and 12c″, which extend through the waterfall cover 12 in the vertical direction to discharge water from the waterfall cover 12. That is, water is sprayed onto the waterfall cover 12 from the obliquely upward side of the circumference of the waterfall cover 12 and exits from the bottom of the waterfall cover 12.

[0071] It should be noted that the waterfall cover 12 has a working principle similar to that of a centripetal impeller, that is, during rotation, the water flow at the radial outer edge of the waterfall cover 12 tends to move towards the center of the waterfall cover 12.

[0072] Please see Figure 8 and Figure 9 This application provides a bucket lid assembly 100, including a water bucket lid 50 and an inner lid device 10 in any embodiment of this application.

[0073] The water container lid 50 has an opening 50a, and in a top view of the cylindrical part 1000, the water container lid 50 is roughly in the shape of a ring.

[0074] The inner cover 11 is used to close or open the opening 50a. For example, during the washing process, please refer to... Figure 4 and Figure 5 The inner cover device 10 is in the closed state, closing the opening 50a; when it is necessary to remove the clothing, please refer to... Figure 6 and Figure 7 Simply open the inner cover device 10.

[0075] The water container lid 50 is used to deflect the water flow along the bottom surface of the water container lid 50 to the annular inlet 10a.

[0076] Please see Figure 3 , Figure 5 and Figure 7 This application provides a cylindrical assembly 1000, which includes a water tank 40, a washing drum 20, a drive mechanism 30, and a lid assembly 100 according to any embodiment of this application.

[0077] The washing drum 20 is housed within the water tank 40, with its top open. A pulsator 21 is located at the bottom of the washing drum 20, meaning the washing device is a pulsator-type washing device. The opening 50a is approximately located directly above the washing drum 20.

[0078] A water container lid 50 surrounds the top of the water container 40. The water container lid 50 is used to deflect the water flow that rises along the water container 40 to the annular inlet 10a.

[0079] In this embodiment, during the washing process, the power mechanism 30 drives the impeller 21 and the washing drum 20 to rotate in the same direction. Under the combined action of the impeller 21 and the washing drum 20, the water in the water tank 40 spirals upward along the wall of the water tank 40. After rising to a certain height, it encounters the obstruction of the water tank cover 50 and changes direction. The water flows along the bottom surface of the water tank cover 50 from the radially outer side to the radially inner side of the water tank cover 50. Water exits from the inner edge of the water tank cover 50 and enters the spray cover 12 from the annular inlet 10a. After the water on the spray cover 12 exits from the outlet channels 12c' and 12c″, it enters the washing drum 20 from above, which has a rinsing effect on the clothes in the washing drum 20. This can accelerate the dissolution of detergent and improve the washing effect of the washing equipment.

[0080] The inner cover device 10 of this application embodiment can rotate the spray cover 12 during the water discharge process, and the sprayed water will be scattered to wash the clothes in the washing drum 20. The sprayed water has a wide coverage area, which has a better rinsing effect on the clothes in the washing drum 20, and also has a better three-dimensional visual effect, thus enhancing the product competitiveness.

[0081] In the embodiment of this application, the inner cover 11 closes the opening 50a during the washing process, preventing foam from overflowing from the opening 50a of the water tank lid 50, thus solving the problem of foam overflow. At the same time, when using the tub to wash down jackets, the inner cover can also prevent down jackets from overflowing, acting as a down jacket pressure plate.

[0082] For example, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 The drum assembly 1000 includes a balance ring 70 that surrounds the top of the washing drum 20. Specifically, the inner edge of the water tank lid 50 is higher than the balance ring 70.

[0083] It should be noted that the installation method of the inner lid 11 on the bucket lid is not limited.

[0084] For example, in some embodiments, the inner cover 11 is removably mounted on the water tank lid 50. Specifically, when it is necessary to open the inner cover device 10, the inner cover device 10 can be completely removed from the water tank lid 50, and the inner cover device 10 is completely detached from the water tank lid 50. For example, both opposite ends of the inner cover 11 are fastened to the water tank lid 50 by snap-fit ​​fasteners.

[0085] In other embodiments, the rear end of the inner cover 11 is rotatably connected to the water tank lid 50, and the front end of the inner cover 11 is fastened to the water tank lid 50 by a snap fastener. When it is necessary to open the inner cover device 10, the snap fastener is released and the inner cover 11 is flipped over, for example, the inner cover 11 is flipped over approximately 90°.

[0086] The specific form of the water outlet channels 12c' and 12c″ is not limited. For example, in some embodiments, please refer to [reference needed]. Figure 18 and Figure 19 The water outlet channels 12c' and 12c″ are long grooves that extend from the outer edge of the waterfall cover 12 toward the inner edge of the waterfall cover 12. They can extend in a straight line or in a curved direction.

[0087] In other embodiments, the water outlet channels 12c' and 12c″ are composed of a plurality of small holes arranged from the outer edge of the waterfall cover 12 toward the inner edge of the waterfall cover 12.

[0088] It should be noted that in some embodiments, the rotation axis of the waterfall cover 12 is approximately coincident with the rotation axis of the inner cylinder, while in other embodiments, the rotation axis of the waterfall cover 12 is parallel to the rotation axis of the inner cylinder.

[0089] The power source for rotating the waterfall cover 12 is not limited; it can be driven by an electric motor or by water power. For example, in some embodiments, the inner cover device 10 includes a motor, and the motor shaft drives the waterfall cover 12 to rotate. The motor can be installed on the inner cover 11, the water tank cover 50, or the water tank 40, etc., and there are no restrictions here.

[0090] In some exemplary embodiments, the waterfall cover 12 is able to rotate under the scouring action of the collected water flow. That is, there is no need to configure a motor for the waterfall cover 12. The scouring force generated by the water flow exiting from the inner edge of the water tank cover 50 on the waterfall cover 12 forms a driving torque about the rotation axis of the waterfall cover 12, and the waterfall cover 12 rotates under the action of this driving torque.

[0091] It is understood that in this embodiment, the direction of the scouring force of the water flow on the waterfall cover 12 is eccentric to the rotation axis of the waterfall cover 12, that is, it does not pass through the rotation axis.

[0092] For example, please refer to Figure 9 and Figure 11 The water container lid 50 includes a lid body 52 and a plurality of guide ribs 51 disposed on the bottom surface of the lid body 52. ​​The plurality of guide ribs 51 are radially distributed, and the water flows from between any two adjacent guide ribs 51 along the outer edge to the inner edge of the water container lid 50.

[0093] It should be noted that the shape of the radial end of the guide rib 51 and the angle between the bottom surface of the water outlet of the cover 52 determine the water outlet angle. Therefore, by controlling the shape of the radial end of the guide rib 51 and the angle between the bottom surface of the water outlet of the cover 52, the water outlet direction from the inner edge of the water container cover 50 can be controlled.

[0094] For example, please refer to Figure 13 and Figure 14 The water outlet of the cover 52 has a downwardly inclined water guiding surface 52a, with the angle between the water guiding surface 52a and the horizontal plane being θ. The value of θ can be 5° to 15°, for example, 5°, 8°, 10°, 15°, etc. In this way, the ejected water flow is inclined downwards, but it can still have a large horizontal spray distance.

[0095] For example, please refer to Figure 12 The angle between the radial end of the guide rib 51 and the radius of the water tank cover 50 is β. The value of β can be 15° to 25°, for example, 15°, 18°, 20°, 25°, etc. On the one hand, it can ensure that the water jet direction does not pass through the rotation axis of the spray cover 12, forming a larger driving torque. On the other hand, it can also achieve a larger radial spray distance.

[0096] For example, please refer to Figure 18 The top surface of the waterfall cover 12 has multiple radially distributed flow channels 12a, which are roughly centered on the rotation axis of the waterfall cover 12. Each flow channel 12a has a water outlet channel 12c', 12c″ on its bottom wall. That is, there are multiple water outlet channels 12c', 12c″, which are also radially distributed.

[0097] In this embodiment, the flow channel 12a can constrain the flow path of the water on the waterfall cover 12, so that the water can be distributed relatively evenly in the circumference of the waterfall cover 12. During the rotation of the waterfall cover 12, the water flows out from below the bottom wall of the flow channel 12a, and the water can be thrown more widely, covering a wider area of ​​clothing, with a better rinsing effect and a better visual effect for the user.

[0098] It should be noted that the number of water outlet channels 12c' and 12c″ on the bottom wall of each flow channel 12a can be one or more.

[0099] In this embodiment of the application, "multiple" refers to no fewer than two.

[0100] For example, please refer to Figure 18The waterfall cover 12 includes a cover plate 121 and a plurality of radially distributed baffles 122 protruding from the top surface of the cover plate 121. An outlet channel 12a is defined between two adjacent baffles 122, and an outlet channel 12c' and 12c″ are provided on the bottom wall of each outlet channel 12a.

[0101] Water jets from the inner edge of the water tank lid 50 spray towards the waterfall cover 12. The baffle 122 prevents the water jet from moving circumferentially, and the water jet exerts a scouring force on the baffle 122, which drives the waterfall cover 12 to rotate. In addition, the baffle 122 also improves the structural strength of the cover plate 121.

[0102] The extension shape of the retaining rib 122 is not limited; for example, it can be a straight extension or a curved extension.

[0103] Please see Figure 18 The baffle 122 is curved, with its convex side facing forward in the direction of rotation. This enhances the deflection ability of the water flow, thereby strengthening the scouring effect of the water flow and increasing the driving torque.

[0104] For example, please refer to Figure 17 Along the radial direction inward, the cover plate 121 gradually concave downward. That is to say, the cover plate 121 has a roughly disc-shaped structure with a high periphery and a low center, and the periphery of the cover plate 121 is closer to the inner cover 11 than the central area of ​​the cover plate 121.

[0105] Please see Figure 6 and Figure 7 When the cover 121 is flipped over, since the periphery of the cover 121 is closer to the inner cover 11, the cover 121 makes it easier for the user to take out and put in clothes from the opening 50a of the water bucket cover 50, reducing interference with the user's clothes taking out and putting in clothes.

[0106] For example, please refer to Figure 18 In each flow channel 12a, at least one outlet channel 12c', 12c″ extends along the root of the water-facing side of one of the baffles 122. The water-facing side refers to the side subjected to water flow scouring, that is, the back side along the direction of rotation.

[0107] In this embodiment, when the water flow washes over the water-facing side of the baffle 122, some of the water flows downstream and falls into the water outlet channels 12c' and 12c″, which can promptly discharge some of the water from under the cover plate 121, improving the timeliness of water discharge.

[0108] The number of water outlet channels 12c' and 12c″ provided on the bottom wall of each flow channel 12a is unlimited; there can be one or more.

[0109] For example, the bottom wall of each flow channel 12a is provided with at least two water outlet channels 12c' and 12c″. The first water outlet channel 12c' extends along the root of the water-facing side of one of the baffles 122, and the second water outlet channel 12c″ is located between the first water outlet channel 12c' and the other baffle 122. The length of the second water outlet channel 12c″ is less than the length of the first water outlet channel 12c'.

[0110] In this embodiment, the second water outlet channel 12c″ can also serve as a drainage channel.

[0111] In this embodiment, the first water outlet channel 12c' in each flow channel 12a has a roughly the same shape, forming a first group of radially distributed water outlet channels. The second water outlet channel 12c″ in each flow channel 12a has a roughly the same shape, forming a second group of radially distributed water outlet channels. The two groups of water outlet channels present different water outlet effects, enhancing the user experience.

[0112] It should be noted that the second water outlet channel 12c″ is positioned as close as possible to the radial outer end of the cover plate 121 so as to discharge the water jet that is sprayed onto the radial outer end of the waterfall cover 12 in a timely manner.

[0113] For example, in some embodiments, in a top view of the inner cover device 10, the radial inner end of the second water outlet channel 12c″ is located at a position not exceeding half the length of the flow channel 12a.

[0114] For example, please refer to Figure 17 The inner cover device 10 includes a filter 13, which is detachably disposed below the cover plate 121. Users can choose to install or not install the filter 13 according to their actual needs.

[0115] The filter 13 is connected to the radial inner end of the channel 12a to receive and filter the water flow from the radial inner end of the channel 12a.

[0116] In this embodiment, water that does not exit from the water outlet channels 12c' and 12c″ flows along the flow channel 12a toward the center of the spray cover 12 and eventually enters the filter 13. After being filtered by the filter 13, the water is discharged from the filter 13 and flows toward the clothes in the washing drum 20. That is to say, the inner cover device 10 in this embodiment also has a filtering effect, filtering lint from the water flow.

[0117] When it is necessary to clean the lint inside the filter 13, simply open the inner cover device 10 and remove the filter 13 from the cover plate 121.

[0118] For example, the filter 13 is disposed below the central region of the cover 121. That is, the filter 13 is located at the center of rotation of the waterfall cover 12. During the rotation of the waterfall cover 12, water that does not exit from the water outlet channels 12c' and 12c″ will be concentrated into the filter 13 for filtration.

[0119] In the embodiment where the cover plate 121 is gradually recessed in the radial inward direction, the shape of the cover plate 121 also facilitates the guidance of water flow on its upper surface to the center and into the filter 13. In this embodiment, even when the rotation speed of the spray cover 12 is low, water flow that is not discharged from the water outlet channels 12c' and 12c″ can be concentrated and flowed to the filter 13.

[0120] The specific structure of filter 13 is not limited.

[0121] For example, please refer to Figure 17 and Figure 21 The top side of the filter 13 is open and covers the bottom surface of the cover plate 121. Water flows into the filter 13 from the top side opening.

[0122] Please see Figure 18 and Figure 19 The cover plate 121 is provided with a flow hole 12b at the radial inner end of each flow channel 12a. In the top view projection of the inner cover device 10, the flow hole 12b is located within the projection range of the open part of the filter 13, and the water flows into the filter 13 through the flow hole 12b.

[0123] For example, please refer to Figure 20 and Figure 21 The filter 13 includes a filter screen 133 and a hollow cylinder 131. The top side of the cylinder 131 is open, and the circumferential wall or bottom of the cylinder 131 is provided with a hole 131a. The filter screen 133 is disposed at the hole 131a.

[0124] For example, the water outlet channels 12c' and 12c″ are located outside the projection range of the open portion of the filter 13. That is, the water outlet channels 12c' and 12c″ are spaced apart from the flow holes 12b, and the ends of the water outlet channels 12c' and 12c″ do not extend directly above the filter 13. Water discharged from the water outlet channels 12c' and 12c″ will not enter the filter 13. On the one hand, this allows the water flow at the center of the waterfall cover 12 to converge into the filter 13. On the other hand, it avoids the water outlet channels 12c' and 12c″ from being too long, thus ensuring the structural strength of the waterfall cover 12.

[0125] The detachable connection method between filter 13 and cover plate 121 is not limited.

[0126] For example, please refer to Figure 21The top of the filter 13 has multiple hooks 132, and the bottom side of the hooks 132 is provided with a first anti-reverse protrusion 13221. For example, the hooks 132 include a horizontal segment 1322 and a vertical segment 1321 connected to each other. The bottom end of the vertical segment 1321 is connected to the top edge of the above-mentioned column 131, and the horizontal segment 1322 extends circumferentially from the top of the vertical segment 1321. The first anti-reverse protrusion 13221 is provided on the bottom side of the horizontal segment 1322.

[0127] Please see Figure 18 The cover plate 121 is provided with a plurality of circumferentially extending slots 12d and a second anti-reverse protrusion 1211 located at the end of the slots 12d. The hook 132 is inserted into the slots 12d and can slide in the slots 12d so that the first anti-reverse protrusion 13221 and the second anti-reverse protrusion 1211 are locked together.

[0128] During assembly, the hook 132 passes through the slot 12d from the bottom side of the cover plate 121, and then rotates at a certain angle. The longitudinal section 1321 slides in the slot 12d. When the first anti-reverse protrusion 13221 contacts the second anti-reverse protrusion 1211, the second anti-reverse protrusion 1211 forces the end of the transverse section 1322 away from the longitudinal section 1321 to deform upward. Continue to rotate the filter 13 until the first anti-reverse protrusion 13221 passes the second anti-reverse protrusion 1211. The transverse section 1322 returns to its original shape under the action of its own elastic restoring force. The first anti-reverse protrusion 13221 is blocked by the second anti-reverse protrusion 1211, making it difficult for the first anti-reverse protrusion 13221 to pass the second anti-reverse protrusion 1211. In this way, the filter 13 can be locked on the cover plate 121. When it is necessary to disassemble the filter 13, rotate the filter 13 in the opposite direction so that the first anti-reverse protrusion 13221 passes over the second anti-reverse protrusion 1211, and then the filter 13 can be removed.

[0129] For example, the second anti-reverse protrusion 1211 is located at the end of the slot 12d in the opposite direction to the rotation direction of the waterfall cover 12. In this way, during the rotation of the waterfall cover 12, the first anti-reverse protrusion 13221 and the second anti-reverse protrusion 1211 will not press against each other in the disengagement direction, reducing the probability of the first anti-reverse protrusion 13221 disengaging from the second anti-reverse protrusion 1211 and improving reliability.

[0130] The specific assembly method of the waterfall cover 12 and the inner cover 11 is not limited, as long as the waterfall cover 12 can rotate relative to the inner cover 11.

[0131] For example, please refer to Figure 17 and Figure 18 The waterfall cover 12 includes a cylindrical portion 123, which is located at the center of the cover plate 121 and generally penetrates the cover plate 121. The inner end of the baffle 122 is connected to the circumferential surface of the cylindrical portion 123, that is, the center of the cylindrical portion 123 is consistent with the center of the cover plate 121.

[0132] It is understandable that the spray cover 12 can be a one-piece molded structure, for example, one-piece injection molding, that is, the cover plate 121, the baffle 122 and the cylindrical part 123 are integrally molded. Of course, the cover plate 121, the baffle 122 and the cylindrical part 123 can also be independent parts and assembled together.

[0133] Please see Figure 17 The inner cover device 10 includes a bushing 14 mounted on the bottom side of the inner cover 11. A stop flange 141 is formed on the bottom edge of the bushing 14. A cylindrical portion 123 is rotatably fitted on the bushing 14. The outer diameter of the stop flange 141 is larger than the inner diameter of the cylindrical portion 123. The bottom end of the cylindrical portion 123 abuts against the stop flange 141 and can rotate on the bushing 14.

[0134] During assembly, the bushing 14 is inserted into the cylindrical part 123 from below the waterfall cover 12. Since the outer diameter of the stop flange 141 is larger than the inner diameter of the cylindrical part 123, the stop flange 141 cannot be inserted into the cylindrical part 123. Then, the bushing 14 is fixed on the inner cover 11. The waterfall cover 12 abuts against the stop flange 141 under its own weight, thus completing the assembly of the waterfall cover 12.

[0135] The method of fixing the bushing 14 and the inner cover 11 is not limited. For example, screws, snap-fit, etc.

[0136] For example, please refer to Figure 17 The inner cover 11 has a protrusion 112 on its bottom side, and the bushing 14 is fitted on the protrusion 112. The bushing 14 has a bottom end cover 142. The screw passes through the bottom end cover 142 from bottom to top and is screwed into the protrusion 112.

[0137] For example, please refer to Figure 15 and Figure 17 The middle area of ​​the inner cover 11 is recessed downward to form a recessed portion 111, and the waterfall cover 12 is connected to the middle area of ​​the recessed portion 111. Specifically, the aforementioned protrusion 112 is formed on the bottom side of the recessed portion 111.

[0138] Please see Figure 5 When the inner cover 11 is in the closed state with the opening 50a closed, the edge of the inner cover 11 abuts against the water tank cover 50, and the recess 111 extends into the water tank cover 50. In this way, with the same structural dimensions as the waterfall cover 12, the position of the waterfall cover 12 can be made as low as possible so as to reliably catch the water flow that comes out from the inner edge of the water tank cover 50.

[0139] For example, one of the inner cover or the water container cover 50 is provided with a sealing ring 15. When the inner cover is in the closed state with the opening 50a closed, the sealing ring 15 surrounds the opening 50a, and the other of the inner cover or the water container cover 50 is in a sealing engagement with the sealing ring 15.

[0140] For example, when the inner cover device 10 is provided with a sealing ring 15, the area around the opening 50a of the water tank lid 50 is used to seal with the sealing ring 15. When the water tank lid 50 is provided with a sealing ring 15, the bottom surface of the inner cover 11 is sealed with the sealing ring 15.

[0141] The sealing ring 15 can improve the sealing performance of the inner cover 11 and the water tank lid 50, and improve the reliability of preventing overflow and foaming.

[0142] For example, please refer to Figure 17 The bottom edge of the inner cover 11 is provided with an annular groove 11a, and the sealing ring 15 is embedded in the annular groove 11a. That is to say, in this embodiment, the sealing ring 15 is provided on the inner cover 11, and water and dirt are not easy to accumulate in the annular groove 11a, which is also convenient for machining the annular groove 11a on the inner cover 11.

[0143] For example, please refer to Figure 14 The water container lid 50 has a reinforcing rib 521 around the opening 50a, and the reinforcing rib 521 protrudes upward. When the inner lid 11 is in the closed state with the opening 50a closed, the reinforcing rib 521 presses against the sealing ring 15, which can further improve the sealing effect.

[0144] Please see Figure 1 and Figure 2 This application provides a washing device, including a housing 60 and a drum assembly 1000 according to any embodiment of this application, wherein the drum assembly 1000 is disposed inside the housing 60.

[0145] The washing equipment includes a vortex washing mode, in which the power mechanism 30 drives the impeller 21 and the washing drum 20 to rotate in the same direction.

[0146] In the washing equipment of this embodiment, in the swirl wash mode, the water flow from the water tank lid 50 enters the washing drum 20 from above, rinsing the clothes inside the washing drum 20, promoting detergent dissolution, accelerating the generation of microbubbles, generating hundreds of millions of microbubbles, thereby improving the washing effect of the washing equipment; since the impeller 21 and the washing drum 20 rotate in the same direction, it can reduce wear on clothes and also play a certain role in preventing tangling.

[0147] Understandably, in the swirling wash mode, the washing drum 20 and the impeller 21 can rotate at the same speed, that is, the impeller 21 and the washing drum 20 rotate synchronously and in the same direction, and there is no relative movement between the impeller 21 and the washing drum 20; there can also be a small speed difference between the impeller 21 and the washing drum 20.

[0148] In related technologies without an inner lid device 10, the swirling wash cycle can only be performed two or three times during the entire washing process, and each swirling wash can only last for a dozen seconds. This is because swirling washes easily generate a large amount of foam. If a single swirling wash lasts a little longer, or if more than three swirling washes are performed, a large amount of foam will overflow from the opening 50a. Therefore, in related technologies, the number of swirling washes and the duration of each wash are significantly limited.

[0149] In the washing equipment of this application embodiment, during the washing process, the inner cover 11 closes the opening 50a, which solves the problem of overflowing foam when the swirl washing time is too long. The swirl washing is performed multiple long washing cycles, such as five or six swirl washing cycles, and the time of a single swirl washing cycle can be increased to more than 30 seconds, thereby improving the washing ratio, reducing clothes tangling, and reducing wear.

[0150] In some embodiments, the washing device also includes a normal washing mode, in which the power mechanism 30 only drives the impeller 21 to rotate, and the washing drum 20 remains stationary. It should be noted that in the normal washing mode, the water in the washing drum 20 will not climb up the wall of the water tank 40, therefore, the water flow will not reach the water tank lid 50.

[0151] For example, please refer to Figure 3 and Figure 8 The water tank lid 50 is provided with a water inlet 50b. During assembly, the end of the water inlet pipe is connected to the water inlet 50b, and washing water is injected into the inner drum through the water tank lid 50.
