Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and specifically to a washing machine with a cleaning device. Background Technology

[0002] The existing design of the filter collection function inside the lifting ribs of the drum washing machine requires users to frequently disassemble and install the lifting ribs in order to clean the filaments, lint, and contaminants collected inside the lifting ribs. This is because the installation and disassembly of the existing structure are all done through the lifting ribs and the inner drum.

[0003] Firstly, the opening part of the existing quick-release lifting rib technology is designed on the surface of the lifting rib. Because it is easy to form unevenness, or the elasticity may decrease over time, causing the opening button and the shell to form an uneven surface. This inevitably creates a risk of damage to clothes (silk materials) due to the unevenness of the lifting rib opening structure when the drum washing machine relies on tumbling to clean clothes.

[0004] Secondly, the existing quick-release lifting rib design does not allow users to unload the lifting rib with a single action. When opening the existing quick-release lifting rib, the user needs to reach into the inner cylinder to find the opening button, which is inconvenient. Moreover, the force applied to the opening structure is not consistent with the direction of lifting rib disassembly. As a result, users may need to use both hands to operate the installation and disassembly, even under conditions where their vision is already limited. This makes the user experience of repeatedly cleaning the inside and collecting contaminants over a long period of time inconvenient and poor, thus adding another disadvantage to the product.

Detailed Implementation

[0062] The present invention will be described below with reference to the accompanying drawings;

[0063] See Figures 1-6 As shown, the present invention discloses a washing machine with a cleaning device 2, which includes an inner drum 1 disposed inside an outer drum, the inner drum 1 being provided with a cleaning device 2, and the cleaning device 2 being connected to the inner drum 1 via a quick-release structure.

[0064] The quick-release structure includes a locking part and a hook part that are separately set on the inner cylinder 1 and the cleaning device 2, and the locking part and the hook part are correspondingly set and matched and connected.

[0065] The hook portion includes a connecting rod 5 and a hook head 4 disposed at one end of the connecting rod 5, the hook head 4 extending from the circumference of the connecting rod 5;

[0066] The locking part includes a locking body 6, a locking chamber is provided inside the locking body 6, and an inlet for the hook head 4 to pass through is provided at the top of the locking body 6, and the inlet is connected to the locking chamber;

[0067] The hook head 4 extends into the locking chamber and connects to the locking part;

[0068] It also includes an anti-detachment structure to prevent the hook head 4 from detaching from the locking part;

[0069] A fluid passage is provided at the location where the cleaning device 2 is located on the inner cylinder 1. The cleaning device 2 is located on the inner circumferential surface of the inner cylinder 1 and the fluid passage is blocked. The fluid passage is connected to the internal area of ​​the cleaning device 2.

[0070] Figure 1 The washing machine shown is a drum washing machine. The cleaning device 2 is a lifting rib. The lifting rib is connected to the inner drum 1 by a quick-release structure, which can promptly clean the lint collected by the collection and filter device 9 inside the lifting rib. It is also convenient and quick to disassemble and assemble. Figure 4 The washing machine shown is a top-loading washing machine. The cleaning device 2 is a collection box. The collection box is connected to the inner drum 1 using a quick-release structure, which can promptly clean the lint collected by the collection filter device 9 in the collection box. It is also convenient and quick to assemble and disassemble.

[0071] In one embodiment, the cleaning device 2 includes a lifting rib or a collection box, on which dehydration holes 7 are evenly distributed. A collection and filtration device 9 is fixedly installed inside the lifting rib or collection box. The collection and filtration device 9 has a fluid inlet 8 and a fluid outlet. A filter screen is sealed on the fluid outlet. The fluid inlet 8 faces the outer cylinder and is sealed and connected to the fluid passage. The collection and filtration device 9 can be configured as required, such as in the prior art. Figure 2 The structure shown can also be configured as the structure of a filter bag in the prior art.

[0072] In one embodiment, the cleaning device 2 includes a lifting rib or a collection box, on which dehydration holes 7 are evenly distributed. A collection and filtration device 9 is fixedly provided on the side of the lifting rib or collection box facing the inner circumferential surface of the inner cylinder 1. The collection and filtration device 9 is provided with a fluid inlet 8 and a fluid outlet, and a filter screen is provided to seal the fluid outlet.

[0073] The collection and filtration device 9 is connected to the fluid inlet and extends into the area between the inner cylinder 1 and the outer cylinder after passing through the fluid inlet. The fluid inlet 8 is arranged circumferentially towards the inner cylinder 1.

[0074] In one embodiment, a flow guiding channel is also included. One end of the flow guiding channel is sealed and connected to the fluid inlet 8 or the fluid passage, and the other end extends into the area between the inner cylinder 1 and the outer cylinder and is arranged circumferentially toward the inner cylinder 1. When the collecting and filtering device 9 is located inside the lifting rib or the collecting box, the purpose of setting the flow guiding channel is to increase the flow rate of the fluid entering the fluid inlet 8, thereby effectively increasing the collection efficiency of the collecting and filtering device 9 in collecting lint in the fluid.

[0075] In one embodiment, see Figure 7 As shown, a one-way opening sealing door 10 is provided on the fluid inlet 8; the function of the one-way opening sealing door 10 is to prevent the lint collected into the collection and filtration device 9 from flowing out of the fluid inlet 8.

[0076] The one-way opening sealing door 10 is installed inside the fluid inlet 8. One end of the one-way opening sealing door 10 is a connecting end, and the corresponding other end is an opening end. The connecting end is connected to the collection and filtration device 9 on one side of the fluid inlet 8.

[0077] In practical use, when the collecting and filtering device 9 is located inside the collecting box or lifting rib, and the lifting rib or collecting box is installed, the fluid inlet 8 faces the fluid passage and is set towards the outer drum of the washing machine. The fluid inlet 8 and the fluid passage are interconnected. A guide channel is set on the outer circumference of the inner drum 1 and connected to the fluid passage to increase the flow rate of fluid entering the fluid inlet 8. A one-way opening sealing door 10 is set at the fluid inlet 8 to prevent the collected lint from flowing out of the fluid inlet 8 through the fluid passage. When the collecting and filtering device 9 is located on one side of the collecting box and extends into the area between the inner drum 1 and the outer drum from the fluid passage, the fluid inlet 8 is set on the corresponding two sides of the collecting and filtering device 9 and is set towards the circumference of the inner drum 1. A one-way opening sealing door 10 is set on the fluid inlet 8 to achieve bidirectional collection of lint when the inner drum 1 rotates forward and backward, and prevents the collected lint from flowing out of the fluid inlet 8, further improving the lint collection efficiency.

[0078] In one embodiment, the side of the collecting and filtering device 9 connected to the connecting end is positioned close to the inner cylinder 1. This arrangement makes the one-way opening sealing door 10 easier to open under fluid impact.

[0079] In one embodiment, the one-way opening sealing door 10 is a one-way opening sealing door 10 that opens due to fluid impact and can close automatically;

[0080] The fluid inlet 8 is sealed with at least two one-way opening sealing doors 10, and adjacent one-way opening sealing doors 10 are sealed together. The purpose of setting multiple one-way opening sealing doors 10 is to make the one-way opening sealing doors 10 easier to open.

[0081] In one embodiment, the anti-detachment structure is an elastic anti-detachment structure that is released when force is applied in a single direction;

[0082] The direction of force for releasing the anti-detachment structure is the same as the direction of force for disengaging the hook and locking parts. The specific structural setup can be referred to in the following two implementation methods. With this setup, the anti-detachment structure can be released and the hook and locking parts can be disengaged with a single application of force, thus achieving convenient disassembly. Conversely, convenient installation can be achieved by applying force in the opposite direction.

[0083] In one embodiment, as shown in 15, the anti-detachment device includes a return spring 18 and an anti-detachment block 20. A stepped blind hole is provided on the side of the connecting rod 5 away from the hook head 4. The cross-sectional area of ​​the open end of the stepped blind hole is smaller than the cross-sectional area of ​​the other end. One end of the anti-detachment block 20 extends into the stepped blind hole, matches the stepped blind hole, and is slidably connected.

[0084] An axial fixing block is fixedly installed on one end of the anti-detachment block 20 that extends into the blind hole of the step. The cross-sectional area of ​​the axial fixing block is larger than the cross-sectional area of ​​the opening end of the blind hole of the step. The axial fixing block is connected to the bottom of the blind hole of the step through a return spring 18.

[0085] The shape of the other end of the anti-detachment block 20 matches the inner wall of the locking chamber away from the limiting structure. The locking chamber away from the limiting structure is provided with a convex rib 19 with an arc cross-section near the entrance. The convex rib 19 protrudes towards the interior of the locking chamber. When the hook head 4 is located in the locking chamber, the hook head 4 is engaged with the limiting structure, and the anti-detachment block 20 is engaged on the side of the convex rib 19 facing the locking chamber away from the entrance.

[0086] When the hook head 4 extends into the locking chamber, the anti-detachment block 20 pops out and is connected to the limiting rib 19. At this time, the hook head 4 is located below the limiting plate 15 and connected to the limiting plate 15, realizing a reliable connection between the hook part and the locking part, and realizing a quick connection between the two external devices where the hook part and the locking part are located. When it is necessary to remove the hook head 4 from the locking chamber, pull the connecting rod 5 towards the rib 19, the return spring 18 is compressed, the hook head 4 is disengaged from the limiting structure, and then pull the connecting rod 5 away from the locking part. Since the cross-section of the rib 19 is arc-shaped, the anti-detachment block 20 passes over the rib 19, and the hook head 4 is removed from the locking chamber, realizing a quick disassembly of the two external devices where the hook part and the locking part are located.

[0087] In one embodiment, see Figures 8-11 As shown, the anti-detachment structure includes corresponding anti-detachment columns 11 and anti-detachment plates 12. The anti-detachment columns 11 are fixedly installed on the inner circumferential surface of the inner cylinder 1 or on the cleaning device 2. The anti-detachment plates 12 are fixedly installed on the cleaning device 2 or the inner circumferential surface of the inner cylinder 1 by a plurality of anti-detachment springs 13.

[0088] The anti-detachment column 11 is configured as a plurality of units;

[0089] The anti-detachment column 11 and anti-detachment plate 12 are arranged sequentially along the direction in which the hook head 4 extends from the connecting rod 5;

[0090] When the hook head 4 is inserted into the locking chamber and connected to the locking part, the anti-detachment column 11 abuts against the anti-detachment plate 12, and the anti-detachment spring 13 is compressed.

[0091] In use, the hook or locking part is respectively set on the side of the lifting rib or collection box facing the inner cylinder 1. The anti-detachment column 11 of the anti-detachment structure is set on the side of the inner cylinder 1 facing the lifting rib or collection box. The anti-detachment plate 12 is set on the lifting rib or collection box. Since the anti-detachment column 11 and anti-detachment plate 12 are arranged sequentially along the direction in which the hook head 4 extends from the connecting rod 5, when the hook head 4 extends into the locking chamber, the anti-detachment spring 13, under the limiting action of the anti-detachment column 11, pushes the anti-detachment plate 12 to drive the hook head 4 to extend into the lower part of the limiting structure and connect with the limiting structure, ensuring a reliable connection between the hook part and the locking part. When it is necessary to disassemble the lifting rib or collection box, push the lifting rib or collection box in the opposite direction to overcome the elasticity of the anti-detachment spring 13, so that the anti-detachment spring 13 is compressed and the hook head 4 is disengaged from the limiting structure, so that the hook head 4 can be disengaged from the locking chamber, realizing the disassembly of the lifting rib or collection box from the inner cylinder 1.

[0092] The locking body 6 is also provided with a limiting structure for connecting the hook head 4 and restricting the hook head 4 from leaving the locking chamber. The limiting structure is matched and connected to the hook head 4.

[0093] The limiting structure is a limiting plate 15;

[0094] The insertion port is located at one end of the top of the latch chamber. One end of the limiting plate 15 is fixedly connected to the latch body 6, and the other end of the limiting plate 15 extends into the latch chamber from the end of the top of the latch chamber away from the insertion port.

[0095] When in use, the hook head 4 extends into the locking chamber and is located below the limiting plate 15, and is connected to the limiting plate 15 to realize the connection between the hook part and the locking part.

[0096] An auxiliary structure for increasing the friction between the hook head 4 and the inner wall of the limiting chamber is fixedly provided on the side of the locking chamber away from the inlet or on the side of the hook head 4 away from the connecting rod 5;

[0097] The auxiliary structure includes an elastic reset device. When the hook part is connected to the locking part, one end of the elastic reset device is connected to the side of the locking chamber away from the entrance, and the other end is connected to the hook part. The elastic reset device is located directly below the entrance and is in an elastic energy storage state.

[0098] The elastic reset device can be an auxiliary spring plate 17, see [link / reference] Figure 14As shown, one end of the auxiliary spring plate 17 is connected to the end face of the hook portion extending into the locking chamber or to the bottom of the locking chamber, and the other end of the auxiliary spring plate 17 extends obliquely away from the end face of the hook portion extending into the locking chamber or the bottom of the locking chamber. The auxiliary spring plate 17 is configured such that after the hook head 4 enters the locking chamber and connects with the limiting structure, the auxiliary spring plate 17 pushes the hook head 4 towards the limiting structure, thereby increasing the friction between the hook head 4 and the connecting surface of the limiting structure, further ensuring the reliability of the connection. When the hook portion is about to disengage from the locking chamber, the connecting rod 5 is pulled. At this time, the auxiliary spring plate 17 is in an elastic deformation state due to being squeezed, maintaining the squeezing force on the hook head 4 towards the connecting rod 5. When the hook portion disengages from the locking chamber, the auxiliary spring plate 17 resets and pushes the hook portion out of the locking chamber.

[0099] The elastic reset device can be an auxiliary spring 16, see [reference]. Figure 15 As shown, a stepped auxiliary cavity is also provided at the bottom of the latching chamber. One end of the auxiliary cavity is a large-diameter end and the other end is a small-diameter end. The cross-sectional area of ​​the large-diameter end is larger than that of the small-diameter end. The small-diameter end is connected to the latching chamber. The push head is matched and slidably arranged in the large-diameter end. A push column is fixedly connected to the push head. The end of the push column away from the push head extends out of the small-diameter end and into the latching chamber, and is arranged corresponding to the opening on the upper part of the latching chamber. The end of the push head away from the push column is connected to the end of the auxiliary cavity away from the small-diameter end through an auxiliary spring 16.

[0100] After the hook head 4 enters the locking chamber and connects with the limiting structure, the push head, under the action of the auxiliary spring 16, pushes the hook head 4 toward the limiting structure, thereby increasing the friction between the hook head 4 and the connecting surface of the limiting structure, and further ensuring the reliability of the connection. When the hook part is about to disengage from the locking chamber, the push column is squeezed at this time, and the auxiliary spring 16 is in an elastic deformation state, maintaining the squeezing force on the hook head 4 toward the connecting rod 5. When the hook part disengages from the locking chamber, the auxiliary spring plate 17 resets, and the push column pushes the hook part out of the locking chamber.

[0101] In one embodiment, see Figure 12 , Figure 13 As shown, the area on the inner cylinder 1 where the cleaning device 2 is installed is provided with an auxiliary reinforcing structure to enhance the strength of the inner cylinder 1;
