Description

TECHNICAL FIELD

[0001] The present application relates to the field of washing machines, in particular to a space compensation mechanism for a flexible washing bag, a washing machine and a space compensation method. BACKGROUND

[0002] Washing machines are commonly used devices in people's lives, providing great convenience for people's daily life. The common washing method of washing machines is to achieve cleaning through the relative friction between the rotating motion of water flow and the washing objects. However, this method may cause the water flow to rotate with the washing objects, resulting in entanglement between the washing objects. Users need to constantly untangle the entangled washing objects when taking them out, which makes it difficult to take out the washing objects and may damage the washing objects. To solve the above problems, a rigid washing barrel can be replaced with a flexible washing bag, and a similar rubbing motion is performed on the flexible washing bag to cause friction between the inner wall of the flexible washing bag and the washing objects, thereby achieving cleaning.

[0003] After the washing objects are washed, they need to be dehydrated. For a rigid washing barrel, centrifugal force is usually used to throw out the water in the washing objects, thereby achieving dehydration. However, for a flexible washing bag, the centrifugal method is no longer applicable. Instead, the flexible washing bag is usually squeezed to fully squeeze out the water in the washing objects, thereby achieving dehydration. Since the flexible washing bag itself does not have supporting force, a rigid supporting mechanism such as a rigid frame can be used to assist in supporting and maintaining the required shape of the flexible washing bag. When the flexible washing bag is squeezed and deformed, if the displacement range exceeds the limit of deformation, the tension of the flexible washing bag will be transmitted to the rigid frame, causing the connecting part between the flexible washing bag and the rigid frame to bear an increased force, which may result in damage.

[0004] In summary, when the flexible washing bag is squeezed for dehydration, how to reduce the probability of damage to the connecting part between the flexible washing bag and the rigid frame is a technical problem that needs to be solved. SUMMARY

[0005] The present application aims to provide a space compensation mechanism for a flexible washing bag, a washing machine and a space compensation method, which can use the space for movement of the supporting assembly to compensate for the reduced space of the flexible bag body due to squeezing when the flexible washing bag is squeezed for dehydration, effectively reducing the probability of damage to the connecting part.

[0014] Further, the reset movable piece is slidably connected to the main frame.

[0015] Further, the reset movable piece is rotatably connected to the main frame, and the compression space serves as a rotating space of the reset movable piece.

[0016] Further, the reset piece is an elastic piece which can be elastically deformed or the reset piece is a telescopic piece which has a reset function.

[0017] Further, the elastic piece is a compression spring or a tension spring which has different elastic potential energy according to different deformation amounts, or the elastic piece is a constant force spring which has constant elastic potential energy according to different deformation amounts.

[0018] A washing machine comprises the space compensation mechanism and a squeezing mechanism which can make the flexible bag contract and deform, the washing bag is assembled in the main frame, the squeezing mechanism is assembled on the main frame, and the washing bag has a drainage hole.

[0019] Further, the extrusion mechanism is a gas injection and extraction device; the main frame is provided with a docking hole, and the washing bag is provided with a docking head capable of docking with the docking hole; the docking hole is connected with the gas injection and extraction device; or the main frame is provided with a docking head, and the washing bag is provided with a docking hole capable of docking with the docking head; the docking head is connected with the gas injection and extraction device.

DETAILED DESCRIPTION

[0041] All features disclosed in this specification, and / or the steps of any method or process specified in this specification, can be combined in any combination, unless specific combinations are excluded.

[0042] Any of the features disclosed in this specification, unless explicitly stated otherwise, can be replaced by alternative features functioning similarly or by equivalent features.

[0043] Example 1

[0044] As shown in Figure 1 - Figure 9 A space compensation mechanism for a flexible washing bag, comprising a main frame 1 and a washing bag 2 which can be assembled in the main frame 1, the washing bag 2 having a flexible bag body 23 and a supporting assembly 22 which supports the flexible bag body 23, the supporting assembly 22 being movable relative to the main frame 1 and the main frame 1 having a compression space 12 for the movement of the supporting assembly 22; by moving the supporting assembly 22 in the compression space 12 relative to the main frame 1, the space for the movement of the supporting assembly 22 is used to compensate for the space reduced by the contraction of the flexible bag body 23, avoiding the pulling of the flexible bag body 23 and the supporting assembly 22 when the flexible bag body 23 is contracted, thereby effectively reducing the probability of damage to the connecting part of the flexible bag body 23 and the supporting assembly 22.

[0045] In the present embodiment, regarding the connecting mode of the supporting assembly 22 and the flexible bag body 23, there are several feasible implementation modes.

[0046] The first implementation mode is that the supporting assembly 22 has a mounting plate for mounting the washing bag 2, the mounting plate being provided with a taking and placing opening 21 for taking and placing washing articles into the flexible bag body 23, and the taking and placing position of the flexible bag body 23 surrounding the taking and placing opening 21 and being fixedly connected with the mounting plate.

[0047] For the first implementation mode, a cover assembly for sealing the taking and placing opening 21 is provided in cooperation with the mounting plate, the cover assembly comprising a cover body 24 and a frame, the frame being fixedly connected with the mounting plate and the taking and placing opening 21 being located in the frame, and the cover body 24 being movably connected with the frame to open or close the frame, in the present embodiment, the movable connection mode between the cover body 24 and the frame can be selected as a sliding or rotating connection mode, both of which can enable the cover body 24 to open or close the frame, thereby opening or closing the taking and placing opening 21, and further enabling the user to conveniently take or place washing articles from or into the taking and placing opening 21. Of course, it should be noted that the supporting assembly 22 can also be constituted only by the cover assembly.

[0048] In the second embodiment, the flexible bag 23 has a loading / unloading opening 21 at the location for taking out and putting in laundry. The loading / unloading opening 21 is equipped with a sealing structure similar to a sealing zipper or sealing strip to seal the opening. When taking out or putting in laundry, the user only needs to open the sealing structure. The support assembly 22 has an mounting plate for mounting the laundry bag 2. The mounting plate can be directly fixedly connected to the top or side of the flexible bag 23. In this method, the loading / unloading opening 21 is located on the side of the flexible bag 23, or near the top of the flexible bag 23. Alternatively, an opening ring is provided between the mounting plate and the flexible bag 23, and the opening / unloading opening 21 is opened or closed by opening or closing the opening ring. Or, the mounting plate has a mounting hole for fixedly connecting with the flexible bag 23. In this method, the loading / unloading opening 21 is located on the top of the flexible bag 23, and the top of the flexible bag 23 passes through the mounting hole and is fixedly connected to the mounting plate.

[0049] In this embodiment, the washing bag 2 can be placed directly inside the main frame 1, or assembled inside the main frame 1 by connecting it to the main frame 1 via the support component 22. In both cases, the support component 22 can move relative to the main frame 1. Specifically, the support component 22 can move within the main frame 1 by translation or rotation. Both translation and rotation can cause relative movement with the main frame 1. The space of this relative movement is the compression space 12, which can compensate for the space reduction after the flexible bag body 23 is compressed.

[0050] Example 2

[0051] Based on Example 1, further feasible specific implementation methods for the "support component 22" are proposed.

[0052] The first implementation method, such as Figure 9 As shown, the support component 22 is a support plate 222. In this embodiment, the support plate 222 is the mounting plate in Embodiment 1. The support plate 222 is assembled on the top of the flexible bag body 23 and located inside the main frame 1. The support plate 222 can be connected to the main frame 1 or not, as long as the support plate 222 can move up and down horizontally. The compression space 12 is the internal space of the main frame 1 that allows the support plate 222 to move horizontally.

[0053] Specifically, when the flexible bag 23 is gradually contracted, the space occupied by the flexible bag 23 is reduced, and the flexible bag 23 with the support plate 222 moves downward in the compression space 12 in the main frame 1, so as to compensate for the reduced space of the flexible bag 23, so as to achieve the purpose of space compensation; of course, in the embodiment, the support plate 222 is not connected with the main frame 1, and the support plate 222 can naturally move along the traction direction of the flexible bag 23 in the compression space 12; or the support plate 222 is slidingly connected with the main frame 1, that is, the inner wall of the main frame 1 is provided with a sliding groove for movement of the support plate 22, the support plate 222 is slidingly connected with the sliding groove, and the sliding stroke direction of the sliding groove is upward and downward, so as to constrain the support plate 222 by the inner wall of the main frame 1; this way can also realize the sliding of the support plate 222 in the compression space 12, and due to the constraint, the sliding direction of the support plate 222 is more determined and the sliding is more stable, which is convenient for subsequent resetting work.

[0054] The second embodiment, as shown in Figure 7 The support assembly 22 is two connected plates 221 that are rotatably connected with each other, and any one of the two connected plates 221 can be used as the mounting plate as described in embodiment 1, that is, the taking and placing opening 21 is arranged on any one of the two connected plates 221; the two connected plates 221 can be rotatably connected with each other through a rotating shaft or a hinge, all the connected plates 221 are connected with the top of the flexible bag 23 and located in the main frame 1, and the compression space 12 is the internal space of the main frame 1 that can rotate the two connected plates 221; when the flexible bag 23 is contracted, the space occupied by the flexible bag 23 is reduced, and the flexible bag 23 with the two connected plates 221 rotates downward in the compression space 12 in the main frame 1, so as to compensate for the reduced space of the flexible bag 23, so as to achieve the purpose of space compensation.

[0055] It should be noted that, in order to reduce the complexity of movement and make the washing bag 2 easier to reset, the rotating shaft can be connected with the inner wall of the main frame 1, so as to avoid the two connected plates 221 from moving as in the first embodiment.

[0056] The third embodiment, as shown in Figure 8As shown, the support assembly 22 is two mutually rotating connecting plates 221, and the two connecting plates 221 are respectively fixed plates 2211 and movable plates. The fixed plate 2211 is assembled on the side of the flexible bag body 23, and the movable plate is connected with the top of the flexible bag body 23. The movable plate is equivalent to the mounting plate described in Embodiment 1, and the taking and placing opening 21 is arranged on the movable plate. The fixed plate 2211 and the movable plate are located in the main frame 1, and the compression space 12 is the internal space of the main frame 1 which can rotate the movable plate. The fixed plate 2211 and the movable plate can be connected with each other through a rotating shaft or a hinge. By rotating the movable plate around the fixed plate 2211, the relative movement of the movable plate in the compression space 12 and the main frame 1 is realized. When the flexible bag body 23 is contracted, the space occupied by the flexible bag body 23 is reduced, and the flexible bag body 23 with the movable plate rotates downward in the compression space 12 of the main frame 1, so as to compensate for the reduced space of the flexible bag body 23, and achieve the purpose of space compensation.

[0057] In the embodiment, since the fixed plate 2211 is installed on the side of the flexible bag body 23, the fixed plate 2211 is constrained by abutting against or fitting with the inner wall of the main frame 1, that is, the fixed plate 2211 can be not connected with the main frame 1, so as to facilitate taking and placing the washing bag 2.

[0058] Of course, in the embodiment, if the fixed plate 2211 is not connected with the main frame 1, the abutting constraint or the fitting constraint between the fixed plate 2211 and the main frame 1 is unstable, that is, when the flexible bag body 23 is compressed, the flexible bag body 23 will pull the fixed plate 2211 to shake, so as to easily cause fatigue damage between the flexible bag body 23 and the fixed plate 2211. Therefore, the fixed plate 2211 and the inner wall of the main frame 1 are detachably connected or fixedly connected, so that the fixed plate 2211 can be stably constrained by the main frame 1. Of course, the detachable connection can also achieve the design purpose of facilitating taking and placing the washing bag 2.

[0059] Embodiment 3

[0060] On the basis of any one of the embodiments in Embodiments 1-2, further feasible embodiments are further proposed.

[0061] The compression space 12 is provided with a limiting structure for limiting the active position of the support assembly 22. The limiting structure limits the maximum position of the movement of the support assembly 22, so as to avoid that the support assembly 22 rotates or translates too much, moves to the washing objects, blocks the air suction port to affect air suction, or affects the extrusion mechanism to extrude the flexible bag body 23.

[0062] Specifically, the limiting structure can be a stopper capable of abutting against a moving part in the support assembly 22. The moving part in the support assembly 22 (hereinafter collectively referred to as a "part" for the convenience of description and saving the length of the description) is any one of the support plate 222, the connecting plate 221 or the movable plate in the embodiment 2, which has two limit positions in the movement stroke, i.e. an upper limit position and a lower limit position. The upper limit position is the normal installation position, i.e. the position after resetting. The stopper is assembled at the lower limit position and capable of stopping the part.

[0063] Alternatively, the limiting structure is a structure capable of restricting the part, such as the sliding groove 11 capable of limiting the movement of the part in the support assembly 22, or a hinge capable of limiting the rotation angle of the part.

[0064] Embodiment 4

[0065] On the basis of any one of the embodiments 1-3, an implementable mode of the resetting mechanism 3 is proposed.

[0066] Specifically, as shown in Figures 1-6 After the flexible bag body 23 is compressed (e.g. the air in the flexible bag body 23 is extracted and the flexible bag body 23 is compressed under the action of the atmospheric pressure), the support assembly 22 moves away from the normal installation position following the movement of the flexible bag body 23. In order to enable the user to open the washing bag 2 at the first time to take or add the washing articles from the washing bag 2, it is necessary to restore the support assembly 22 to the normal installation position, i.e. resetting. In the embodiment, the resetting of the support assembly 22 can be completed under the action of the support assembly 22 itself or the resetting mechanism 3. For the resetting of the support assembly 22, see the following description of the specification.

[0067] The first implementable mode is to inflate the compressed flexible bag body 23 with the pressure air. Since the bottom of the flexible bag body 23 is restricted by the main frame 1, the space in the main frame 1 and located at the top of the flexible bag body 23 is the free expansion space of the flexible bag body 23, i.e. the flexible bag body 23 restores the deformation to the outside of the main frame 1 and pushes the support assembly 22 to make the resetting movement, so that the support assembly 22 is restored to the normal installation position.

[0068] The second implementable mode is that the flexible bag body 23 is made of a material with certain deformation recovery ability, such as silica gel. After the compression of the flexible bag body 23 is stopped, the flexible bag body 23 restores the deformation and pushes the support assembly 22 to reset, so that the support assembly 22 is restored to the normal installation position.

[0069] The third possible implementation, the support assembly 22 further comprises a spring, such as a torsion spring, compression spring or extension spring, which is installed between two parts with relative motion; for the support assembly 22 with rotational motion, the spring is a torsion spring, which is installed at the rotational position, such as the rotating shaft; for the support assembly 22 with translational motion, the spring is a compression spring or extension spring, which is installed between the support assembly 22 and the main frame 1; when the flexible bag 23 is compressed and moves with the parts, the parts will make the spring deform and have elastic potential energy; when the compression of the flexible bag 23 is stopped, the spring restores the deformation and releases the elastic potential energy, thereby driving the parts to reset and restoring the support assembly 22 to the normal installation position.

[0070] Of course, in this embodiment, in order to restore the support assembly 22 to the normal installation position, the reset mechanism 3 can also be used, and the description of the reset mechanism 3 will be described in detail below.

[0071] In this embodiment, the reset mechanism 3 can be selected according to the actual part assembly needs to be installed on the main frame 1, as long as it can interact with the support assembly 22; in this specification, the preferred installation position of the reset mechanism 3 is installed in the compression space 12, because the compression space 12 is the space for the movement of the support assembly 22, and no other fixed parts can be installed inside; and the reset mechanism 3 can interact with the support assembly 22, that is, the reset mechanism 3 can also provide space for the movement of the support assembly 22; in order to save the space occupied by the device, therefore, the preferred installation position of the reset mechanism 3 is installed in the compression space 12.

[0072] Specifically, the reset mechanism 3 comprises a reset movable part 31 movably connected with the main frame 1 and a reset part 32 for following or driving the movement of the reset movable part 31; one end of the reset movable part 31 is movably connected with the main frame 1, which includes translational or rotational connection, and the other end of the reset movable part 31 acts on the support assembly 22; the reset part 32 is assembled between the reset movable part 31 and the main frame 1. The movement of the support assembly 22 drives the movement of the reset movable part 31, and the movement of the reset movable part 31 forces the reset part 32 to change state, thereby having reset potential energy for resetting; when the support assembly 22 needs to be reset, the reset potential energy of the reset part 32 is released and acts on the reset movable part 31, so that the reset movable part 31 moves, thereby the reset movable part 31 drives the support assembly 22 to reset, achieving the purpose of restoring the support assembly 22 to the normal installation position.

[0073] The first implementation of the reset movable part 31 in the reset mechanism 3 is as follows: Figures 1-2 , Figures 8-9As shown, the reset movable part 31 is a sliding block 34, and a sliding groove 11 is formed on the inner wall of the main frame 1, the sliding block 34 is in sliding connection with the sliding groove 11, so as to realize the sliding connection between the sliding block 34 and the main frame 1; the reset part 32 is installed in the sliding groove 11, and the reset part 32 is assembled between the sliding block 34 and the main frame 1; the upper end of the sliding block 34 is in relative sliding with the part, so as to avoid the problem of movement interference; for example, the sliding block 34 always abuts against the part to realize the relative sliding between the sliding block 34 and the part; for another example, a stroke groove for the relative sliding between the sliding block 34 and the part is arranged on the part at the connecting position of the part and the sliding block 34, the sliding block 34 is in sliding connection with the stroke groove, so as to realize the sliding between the sliding block 34 and the part, and the stroke groove is arranged to make the connection between the sliding block 34 and the part more stable. Preferably, in the embodiment, the sliding block 34 abuts against the part, which can reduce the friction generated when the sliding block 34 and the part slide relative to each other as much as possible, ensure that the relative sliding can be stably performed, and further ensure that the part can move stably and smoothly, so that the support assembly 22 can move stably and smoothly, thereby reducing and slowing down the pulling at the connecting position of the flexible bag body 23 and the support assembly 22; of course, a roller or a ball can also be arranged on the position of the sliding block 34 in contact with the part, and the rolling friction is used to replace the friction generated by the relative sliding, which can also reduce the friction and ensure that the relative sliding can be stably performed.

[0074] Specifically, in the embodiment, the part rotates into the main frame 1 under the action of the flexible bag body 23, the part pushes the sliding block 34 to slide in the sliding groove 11, the sliding of the sliding block 34 makes the reset part 32 change the state and have reset potential energy; when the support assembly 22 needs to be reset (i.e. after stopping compressing the flexible bag body 23), the reset part 32 restores the state to release the reset potential energy, and the reset potential energy acts on the sliding block 34, so that the sliding block 34 performs a reset movement, and at the same time, the part is reset, i.e. the support assembly 22 returns to the normal installation position.

[0075] The second embodiment about the reset movable part 31 in the reset mechanism 3 is as follows: Figures 3-4As shown, the slider 34 in the first embodiment of the reset movable part 31 is replaced by a support frame 33, and the main frame 1 is provided with a sliding hole for the support frame 33 to slide, one end of the support frame 33 penetrates through the sliding hole and can move up and down along the axis direction of the sliding hole; the other end of the support frame 33 is in contact with the part, and the connection mode of the part can be similar to that of the slider 34; the working mode of the support frame 33 as the reset movable part 31 is the same as that of the slider 34 as the reset movable part 31; compared with the slider 34, because the support frame 33 is connected with the main frame 1 by penetrating through the sliding hole and sliding with the sliding hole, the support frame 33 has an independent moving space and does not occupy the compression space 12 and the inside of the main frame 1, providing space for installing other necessary parts in the inside of the main frame 1.

[0076] The third embodiment of the reset movable part 31 in the reset mechanism 3 is shown in the figure. Figure 7 As shown, one end of the reset movable part 31 is rotationally connected with the inner wall of the main frame 1 through a rotating shaft or a hinge, and the other end of the reset movable part 31 acts on the part of the support assembly 22, and the connection mode of the part can be similar to that of the slider 34, both of which can adopt the abutting mode or the mode of setting a stroke groove on the part at the connection position of the part and the reset movable part 31, so as to realize the relative sliding between the reset movable part 31 and the part, thereby achieving that the reset movable part 31 can push the support assembly 22 to reset and does not appear motion interference.

[0077] Specifically, under the driving of the flexible bag body 23, the parts in the support assembly 22 move or rotate in the main frame 1, the parts push the reset movable part 31, and the reset movable part 31 rotates around the position rotationally connected with the main frame 1, the contact position or the connection position of the reset movable part 31 changes, so that the parts can normally move in the compression space 12, and the reset movable part 31 can normally rotate in the compression space 12; the rotation of the reset movable part 31 changes the state of the reset part 32, which is connected between the reset movable part 31 and the inner wall of the main frame 1, when the support assembly 22 needs to reset (i.e. after stopping compressing the flexible bag body 23), the reset part 32 restores the state to release the reset potential energy, and the reset potential energy acts on the reset movable part 31, so that the reset movable part 31 moves to reset, and at the same time, the parts reset, i.e. the support assembly 22 returns to the normal installation position.

[0078] It should be noted that, compared with the first two embodiments of the reset mechanism 3, the third embodiment of the reset movable component 31 in the reset mechanism 3 does not change the connection position between the reset movable component 31 and the main frame 1, and the compression space 12 serves as the rotation space for the reset movable component 31, thereby reducing the occupation of other positions on the main frame 1 by the reset movable component 31 and ensuring that other parts or mechanisms installed on the main frame 1 have a place to be arranged.

[0079] It should be noted that in the above three embodiments of the reset movable member 31 in the reset mechanism 3, if a groove 11 is provided at the connection position between the reset movable member 31 and the part, and the reset movable member 31 is slidably connected to the groove 11, then the reset member 32 not only serves as a component that can store the energy required for the reset of the support assembly 22, but also serves as a buffer component. Specifically, when the support assembly 22 is reset, it has velocity when it reaches the normal installation position, so the support assembly 22 has momentum. This momentum will cause the support assembly 22 to exceed the normal installation position. Due to the presence of the reset member 32, when the support assembly 22 exceeds the normal installation position, it will constrain the support assembly 22 (i.e., constrain the potential energy generated by the change of state of the reset member 32). This constraint prevents the support assembly 22 from exceeding the normal installation position too much, and also prevents the support assembly 22 from impacting the main frame 1 at the normal installation position with a large momentum, thereby minimizing the damage to the support assembly 22.

[0080] Example 5

[0081] As described above, especially in any embodiment of embodiment 4 regarding the reset movable member 31 in the reset mechanism 3, the reset mechanism 3 includes a reset movable member 31 and a reset member 32. The implementation of the reset movable member 31 has been clearly explained above. The following describes the feasible implementation of the "reset member 32".

[0082] The first embodiment of the reset member 32, as follows: Figures 7-8 As shown, the reset member 32 is either a compression spring or a tension spring. If the reset member 32 is a compression spring, it is installed between the lower end of the reset movable member 31 and the main frame 1. The reset movable member 31 moves into the main frame 1 (actually downwards) under the drive of the support component 22, compressing the compression spring and causing it to deform, thus acquiring elastic potential energy for reset. If the reset movable member 31 is a tension spring, it is installed between the upper end of the reset movable member 31 and the main frame 1. The reset movable member 31 moves into the main frame 1 under the drive of the support component 22, stretching the tension spring and causing it to deform, thus acquiring elastic potential energy for reset.

[0083] The second implementation of the reset element 32 is as follows: Figure 9As shown, the reset member 32 is a pressure medium telescopic member, such as a pressure gas or a pressure liquid, such as a gas pressure telescopic rod or a hydraulic telescopic rod; the pressure medium telescopic member is like a compression spring (such as a positive pressure telescopic member) or a tension spring (such as a negative pressure telescopic member) in the working principle of the present embodiment, and the reset movable member 31 is driven by the support assembly 22 to move into the main frame 1, so that the state of the pressure medium telescopic member changes to have potential energy for resetting.

[0084] It should be noted that in the above two embodiments, the reset member 32 has different potential energy according to the state change degree, specifically, the greater the state change degree of the reset member 32, the greater the potential energy for resetting, such as the greater the compression degree of the compression spring, the greater the elastic potential energy it has; the support assembly 22 can be subjected to greater force when resetting to ensure that the support assembly 22 can be successfully reset.

[0085] Further, when the reset member 32 is a pressure medium telescopic member, the reset mechanism 3 can only have the reset member 32, i.e., the reset movable member 31 and the reset member 32 are both the same pressure medium telescopic member.

[0086] The third embodiment of the reset member 32 is as shown in Figures 1-2 , Figure 3 As shown, the reset member 32 is a constant force spring 35 having constant elastic potential energy according to different deformation amounts, and the constant force spring 35 has constant elastic potential energy within a certain deformation range; specifically, the constant force spring 35 of model 9293K111 has constant elastic potential energy generated within a deformation amount of 10mm-100mm, and has a structure similar to a coil spring. The inner end of the constant force spring 35 is connected to the main frame 1, and the outer end is connected to the reset movable member 31; or the outer end of the constant force spring 35 is connected to the main frame 1, and the inner end of the constant force spring 35 can move with the reset movable member 31. When the reset movable member 31 is driven by the support assembly 22 to move into the main frame 1, the constant force spring 35 is unfolded to have elastic potential energy for resetting.

[0087] It should be noted that the third embodiment of the reset member 32 has smaller space required by the constant force spring 35 compared with the first and second embodiments of the reset member 32, and the size of the elastic force of the constant force spring 35 is always constant during the movement of the support assembly 22, so that the force on the related parts is not too large, thereby reducing the damage to the related parts.

[0088] Example 6

[0089] As shown in Figures 1-9As shown, a washing machine includes a space compensation mechanism disclosed in any one of the embodiments 1-5 and a squeezing mechanism capable of shrinking and deforming the flexible bag 23; the washing bag 2 is assembled inside the main frame 1; the squeezing mechanism is assembled on the main frame 1; after the washing machine completes washing or rinsing, it needs to dehydrate the laundry, and the washing bag has a drain hole from which washing water or rinsing water flows out of the washing bag; when the squeezing mechanism is activated, the squeezing mechanism squeezes the flexible bag 23, the flexible bag 23 is compressed, the internal space of the flexible bag 23 is reduced, thereby squeezing out the washing water or rinsing water located inside the flexible bag 23 or on the laundry, thereby completing the dehydration of the laundry. Therefore, when the flexible bag 23 is compressed, the space occupied by the flexible bag 23 within the main frame 1 is reduced. The flexible bag 23 will pull the support component 22 to follow the movement, and use the space of the support component 22 to compensate for the space reduced by the flexible bag 23 due to the contraction. This avoids the flexible bag 23 pulling on the support component 22 when it contracts, thereby reducing and mitigating the damage caused by the pulling at the connection between the flexible bag 23 and the support component 22.

[0090] In this embodiment, a feasible specific implementation of the "extrusion mechanism" is proposed.

[0091] In the first embodiment, the compression mechanism is an air extraction and injection device; the main frame 1 is provided with a docking hole 4, and the flexible bag body 23 is provided with a connector that can dock with the docking hole 4, the docking hole 4 being connected to the air extraction and injection device; or the main frame 1 is provided with a connector, and the flexible bag body 23 is provided with a docking hole 4 that can dock with the connector, the connector being connected to the air extraction and injection device. After the washing bag 2 is installed, the connector and the docking hole 4 are sealed together; when it is necessary to dehydrate the laundry, the air extraction and injection device extracts air from the flexible bag body 23, the flexible bag body 23 is compressed under the action of pressure difference, and the liquid inside the flexible bag body 23 is discharged.

[0092] In the second embodiment, the squeezing mechanism is a pushing device 5 that can change its own external dimensions, such as a pushing plate or a pushing medium bag, which can change the structure of the space it occupies. The pushing device 5 is installed between the main frame 1 and the flexible bag 23. When the pushing device 5 is working, the space it occupies increases, thereby occupying the space of the flexible bag 23, squeezing the flexible bag 23, and discharging the liquid inside the flexible bag 23.

[0093] Example 7

[0094] like Figures 1-9 As shown, a space compensation method for flexible washing bags, which can be combined with the space compensation mechanism of any one of the embodiments 1-5, includes the following steps:

[0095] S1: through the air injection device to the flexible bag body 23 inside air or through the push device 5 extrusion flexible bag body 23 outer wall, the flexible bag body 23 on the washing bag 2 is gradually contracted under the action of the extrusion mechanism, the volume of the flexible bag body 23 gradually reduces, the space occupied by the washing bag 2 gradually reduces;

[0096] S2: the contraction of the flexible bag body 23 will simultaneously pull the moving parts in the support assembly 22 in the compression space 12, specifically for the parts to rotate or translate in the compression space 12, the compression space 12 is the space in the main frame 1;

[0097] S3: the space of the support assembly 22 movement compensates the space occupation of the flexible bag body 23 contraction, achieves the purpose of space compensation, so as to avoid the connection part of the flexible bag body 23 and the support assembly 22 under the action of the flexible bag body 23 in the contraction, further reduces the probability of damage of the flexible washing bag 23 and the support assembly 22 connection part.

[0098] Further, it further includes step S4: the reset mechanism 3 arranged in the compression space 12 drives the support assembly 22 to reset, so that the washing bag 2 recovers the state before contraction; step S4 includes the following steps:

[0099] S41: in step S2, when the support assembly 22 moves in the compression space 12, the reset movable part 31 in the reset mechanism 3 moves, the reset movable part 31 moves forces the reset part 32 to change state, the reset part 32 changes state after having the potential energy for pushing the reset movable part 31 to reset movement;

[0100] S42: after finishing extruding the flexible bag body 23, when the washing bag 2 needs to be reset, the reset part 32 restores the state, releases the potential energy and acts on the reset movable part 31, the reset movable part 31 resets movement, with the support assembly 22 resets, realizes the washing bag 2 recovers the state before contraction.

[0101] The present application is not limited to the foregoing specific embodiments. The present application extends to any novel feature or any new combination described in this specification, and any new method or process steps or any new combination disclosed.
