Description

Technical Field

[0001] The present invention relates to the field of washing machines, and in particular to an opening and closing mechanism and an opening and closing method of a washing machine. Background Art

[0002] Washing machines are a common household appliance, providing convenience for people's lives. Currently, most washing machines on the market have either top-loading or front-loading doors. Specifically, pulsator washing machines generally have top-loading doors, which require the user to lean forward and reach down to remove laundry. Front-loading washing machines typically have front-loading doors, but this requires the user to squat to remove or add laundry. Both methods require bending over or kneeling, causing discomfort. Furthermore, both methods require additional space, requiring space above or in front of the washing machine for convenient use, making them difficult to use in confined areas.

[0003] To address the aforementioned existing problems, some washing machines have designed a door opening method in which the washing chamber is tilted and rotated out of the main frame. This door opening method not only saves space but also allows users to stand and take out laundry. For example, in the Chinese invention patent application number CN201510057427.X, the washing tub and the main unit are connected by a foldable bracket, and an air spring is used as a telescopic member. One end of the air spring is hinged to the washing tub, and the other end is hinged to the inner wall of the washing machine. By controlling the expansion and contraction of the air spring, the washing tub is rotated around the bracket to achieve the opening or closing of the washing tub. However, the existing solution uses many components such as brackets and telescopic rods, resulting in a complex structure, taking up a lot of space inside the washing machine, and having high maintenance costs. In addition, the washing chamber is connected to multiple components such as the bracket and telescopic rod, making the replacement process of the washing chamber cumbersome and complicated, and the user cannot easily replace the washing chamber. Summary of the Invention

[0005] The technical solution adopted by the present invention is as follows: an opening and closing mechanism of a washing machine, comprising a main frame and a receiving frame rotatably connected to the main frame, wherein a washing compartment capable of being taken out and placed in the receiving frame is provided in the receiving frame; and / or, the receiving frame is detachably connected to the main frame through a rotating mechanism.

[0013] Furthermore, the detection device is connected to an input end of a controller, and an output end of the controller is connected to a locking mechanism capable of automatically unlocking or locking.

[0014] Furthermore, a damper having a buffering effect is provided between the receiving frame and the main frame, the fixed end of the damper is connected to the main frame, and the movable end of the damper can abut against the front end of the receiving frame.

[0015] Furthermore, the damper is connected to a spring, one end of the spring is connected to the damper, and the other end of the spring is connected to the main frame.

[0016] Furthermore, an elastic member is provided between the outer wall of the receiving frame and the inner wall of the main frame, and when the receiving frame is completely located in the main frame, the elastic member is in a deformed state.

[0017] A method for opening and closing a washing machine, the washing machine comprising a main frame and a receiving frame rotatably connected to the main frame, a telescopic assembly being provided between the main frame and the receiving frame, the telescopic assembly being disconnected from the receiving frame; and the method comprising the following steps:

DETAILED DESCRIPTION

[0039] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0040] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0041] Example 1

[0042] like Figure 1 - Figure 7 As shown, an opening and closing mechanism of a washing machine includes a main frame 1, and a receiving frame 2 is rotatably connected to the inside of the main frame 1. A washing bin 3 is provided in the receiving frame 2, and the washing bin 3 is used to accommodate laundry or drying. The receiving frame 2 is rotatably connected to the main frame 1 to achieve the opening of the washing bin 3 by tilting the receiving frame 2 out of the main frame 1. The washing bin 3 follows the receiving frame 2 to tilt and rotate back and forth out of and into the main frame 1, which is convenient for users to take laundry and is more conducive to users using it in a small space, thereby achieving the purpose of saving space.

[0043] In this embodiment, in view of actual conditions, different types of laundry are usually washed separately, that is, different types of laundry use different washing bins 3, which means that the washing bins 3 need to be replaced frequently. Even if the receiving frame 2 is not damaged, there is still a possibility of replacing the washing bin 3. This problem is solved by virtue of the fact that the washing bin 3 can be taken out of or put into the receiving frame 2; and / or the receiving frame 2 is detachably connected to the main frame 1 through a rotating mechanism.

[0044] Specifically, how to enable the washing bin 3 to be taken out of or put into the receiving frame 2 is proposed in this specification as follows.

[0045] In a first feasible specific implementation method, the internal space of the receiving frame 2 matches the external dimensions of the washing bin 3, and the washing bin 31 is directly placed inside the receiving frame 2. The frame of the receiving frame 2 constrains the washing bin 3, and the washing bin 3 can move with the receiving frame 2; when the washing bin 3 needs to be taken out, the washing bin 3 is directly pulled out from the receiving frame 2, and the washing bin 3 can be replaced without disassembling the receiving frame 2, which further facilitates the use of the user.

[0046] In a second feasible specific implementation, the receiving frame 2 and the washing bin 3 can be detachably connected by hanging, snapping, etc., so that the washing bin 3 can be taken out from the receiving frame 2 separately, and the washing bin 3 can be replaced without disassembling the receiving frame 2, which further facilitates the use of the user.

[0047] In this embodiment, the receiving frame 2 is detachably connected to the main frame 1 through a rotating mechanism. On the one hand, the rotating mechanism enables the receiving frame 2 to move out of the main frame 1 by rotation, or / and move into the main frame 1 by rotation, so as to facilitate the taking and adding of laundry and reduce space occupancy; on the other hand, it is convenient to disassemble the receiving frame 2, so as to facilitate the replacement and maintenance of the receiving frame 2. When replacing the washing bin 3, the washing bin 3 and the receiving frame 2 can also be directly disassembled from the main frame 1 together, so as to achieve the purpose of replacing the receiving frame 2 and the washing bin 3 at the same time.

[0048] Example 2

[0049] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0050] like Figure 1 - Figure 4 、 Figure 7 As shown, Figure 1 , Figure 2 As shown, the main frame 1 is divided into front and rear ends, and the receiving frame 2 rotates relative to the main frame 1 between the front and rear ends of the main frame 1 around the rotating mechanism. Therefore, the rotating mechanism can be set at a position close to the front end of the main frame 1, and the rotating axis of the rotating mechanism is perpendicular to the front and rear direction of the main frame 1; specifically, the following implementation method of the rotating mechanism is proposed in this embodiment.

[0051] Regarding the first embodiment of the rotating mechanism, the rotating mechanism is a rotating shaft 4, the rotating axis of the rotating mechanism is the axis of the rotating shaft 4, and the receiving frame 2 is assembled on the rotating shaft 4; the rotating shaft 4 is rotatably connected to the receiving frame 2 and / or any one or two components in the main frame 1, so that the receiving frame 2 can rotate relative to the main frame 1; or the rotating mechanism is at least two rotating shafts 4, all rotating shafts 4 are coaxial and evenly installed between the receiving frame 2 and the main frame 1, and the receiving frame 2 rotates with the common axis of all rotating shafts 4 as the rotation axis.

[0052] Specifically, in this embodiment, regarding the first embodiment of the rotating shaft 4, the rotating shaft 4 is fixedly connected to the main frame 1, and the receiving frame 2 is rotatably connected to the rotating shaft 4, so that the receiving frame 2 can rotate around the rotating shaft 4 to complete the relative rotation of the receiving frame 2 and the main frame 1; this method does not require disassembly of the connection between the rotating shaft 4 and the main frame 1 when disassembling the receiving frame 2.

[0053] In this embodiment, regarding the second embodiment of the rotating shaft 4, the rotating shaft 4 is fixedly connected to the receiving frame 2, and the rotating shaft 4 is rotatably connected to the main frame 1, thereby realizing the relative rotation of the receiving frame 2 and the main frame 1; this method only requires disassembling the connection between the rotating shaft 4 and the main frame 1 when disassembling the receiving frame 2.

[0054] In this embodiment, regarding the third embodiment of the rotating shaft 4, the rotating shaft 4 is rotatably connected to the receiving frame 2 and the main frame 1 to realize the relative rotation of the receiving frame 2 and the main frame 1; this method is not only convenient for replacing or repairing the receiving frame 2, but also allows the rotating shaft 4 to be disassembled to realize the replacement of the rotating shaft 4 to match receiving frames 2 of different sizes and models.

[0055] In the above three embodiments of the rotating shaft 4, the rotating connection position of the rotating shaft 4 is a detachable connection position, and the detachable connection method of the rotating shaft 4 and the main frame 1 and / or the receiving frame 2 can use a conventional detachable connection method, such as using gaskets, nuts, bearings and other parts to realize a rotating and detachable connection method; the specific connection structure depends on the actual situation and the installation position; the receiving frame 2 and the main frame 1 are connected to each other by a detachable rotating connection method, which can facilitate the disassembly of the receiving frame 2, thereby facilitating the replacement of the washing bin 3, and the maintenance and replacement of the receiving frame 2; and, the rotating method uses a minimum of parts to realize the tilting and rotating of the receiving frame 2 out of the main frame 1 to open the washing bin 3, which is convenient for the user to take the washing clothes, and is more conducive to the user to use in a small space, thereby achieving the purpose of saving space.

[0056] Regarding the second embodiment of the rotation mechanism, the rotation mechanism is a hinge, which is installed between the receiving frame 2 and the main frame 1, and the receiving frame 2 can rotate relative to the main frame 1 around the hinge; in order to ensure the stable rotation of the receiving frame 2, a slide groove matching the movement trajectory of the receiving frame 2 can be provided on the main frame 1, and the receiving frame 2 slides with the slide groove, and the slide groove supports the receiving frame 2 to rotate in and out of the main frame 1, thereby reducing the shaking amplitude of the receiving frame 2.

[0057] Example 3

[0058] like Figure 1-Figure 5 As shown, based on any one of the implementation methods in Examples 1-2, a specific implementation method that can be implemented is further proposed.

[0059] A feasible specific implementation method is that the extreme position of the receiving frame 2 rotating out of the main frame 1 is the open position, and the extreme position of the receiving frame 2 rotating into the main frame 1 is the closed position; when the receiving frame 2 is in the open position, the front end of the receiving frame 2 abuts against the main frame 1; when the receiving frame 2 is in the closed position, the rear end of the receiving frame 2 abuts against the main frame 1, limiting the rotatable stroke of the receiving frame 2, so that the receiving frame 2 rotates between the open position and the closed position, avoiding excessive rotation angle of the receiving frame 2, and reducing the difficulty for the user to take the laundry.

[0060] In a feasible specific implementation manner, the opening and closing mechanism further includes a telescopic component 5 for pushing the receiving frame 2 to rotate; the telescopic component 5 can push the receiving frame 2 from the closed position to the open position.

[0061] In this embodiment, the telescopic component 5 can extend and reset. When extending, the telescopic component 5 will give kinetic energy to the receiving frame 2, that is, push the receiving frame 2 to rotate outside (front) of the main frame 1, so that the washing bin 3 moves to the outside of the main frame 1, and the washing machine is opened, making it convenient for users to take and put down the laundry.

[0062] Furthermore, in this embodiment, the telescopic component 5 is not connected to the receiving frame 2. On the one hand, the telescopic component 5 is fixedly connected to the main frame 1 without motion interference. There is no need to specially provide a rotating part on the telescopic component 5 to connect the telescopic component 5 and the main frame 1 to overcome motion interference. The structure is simple and the installation is convenient; the use of internal parts of the washing machine is reduced; on the other hand, the telescopic component 5 is not connected to the receiving frame 2, which reduces the connection positions that need to be disassembled when disassembling the receiving frame 2 or the washing bin 3, thereby achieving quick and convenient repair and replacement when repairing and replacing the washing bin 3 or the receiving frame 2.

[0063] like Figure 5 As shown, regarding the structure of the telescopic component 5, in this embodiment, the first optional specific implementation method is that the telescopic component 5 is a hard component and an electric push rod can be used. The structure of the electric push rod includes a fixed seat 51 and a push rod 52. The push rod 52 can be translated along the stroke direction of the fixed seat 51. The fixed seat 51 of the electric push rod is connected to the main frame 1 as a fixed end, and the push rod 52 of the electric push rod is able to contact the back or bottom of the receiving frame 2 as a movable end; when the electric push rod is working, the receiving frame 2 is forced to have an initial velocity moving outward from the main frame 1, thereby generating a rotational movement outward from the main frame 1, thereby achieving the purpose of opening the washing bin 3.

[0064] Furthermore, in this embodiment, a specific embodiment, a movable block 54 can be provided at the front end of the push rod 52, and the movable block 54 replaces the push rod 52 to contact the back or bottom of the receiving frame 2; the movable block 54 is fixedly connected to the push rod 52. By providing the movable block 54, the contact area between the telescopic component 5 and the receiving frame 2 is increased, thereby achieving the purpose of reducing the rigid impact of the push rod 52 on the receiving frame 2 and improving the service life of the receiving frame 2.

[0065] Furthermore, the movable block 54 can be made of a material that can produce elastic deformation, such as rubber that can produce elastic deformation, to achieve a buffering effect, reduce the rigid impact on the receiving frame 2, and ensure the service life of the receiving frame 2.

[0066] Furthermore, a deceleration member can be provided at the front end of the push rod 52, and the deceleration member is eccentrically connected to the push rod 52, which can effectively prevent the push rod 52 of the electric push rod from suddenly being subjected to a large rigid impact on the receiving frame 2 when it contacts the receiving frame 2. That is, when the electric push rod contacts the receiving frame 2, the deceleration member will rotate eccentrically, and the receiving frame 2 will be subjected to a weaker initial velocity. As the push rod 52 continues to extend, the eccentric rotation of the deceleration member continues to move, and the speed difference between the receiving frame 2 and the push rod 52 gradually decreases, thereby further reducing the rigid impact on the receiving frame 2 and ensuring the service life of the receiving frame 2.

[0067] Regarding the structure of the telescopic component 5, in this embodiment, the second optional specific implementation method is that the telescopic component 5 is an elastic component, such as a spring push rod. The structure of the spring push rod also includes a fixed seat 51 as a fixed end and a push rod 52 as a movable end, except that a compressible compression spring is arranged between the push rod 52 and the fixed seat 51. When the receiving frame 2 is located in the main frame 1, the compression spring is in a compressed state and has elastic potential energy; when the washing machine needs to be turned on, that is, when the washing bin 3 is rotated to the outside of the main frame 1, the compression spring is not constrained to recover the deformation and release the elastic potential energy, and the receiving frame 2 is subjected to the elastic force transmitted by the push rod 52 and has a rotation movement outside the main frame 1, thereby achieving the purpose of turning on the washing machine.

[0068] It should be noted that in this embodiment, due to the presence of the compression spring, the release of its elastic force is a gradual process. In addition, from the initial static state of the receiving frame 2 to the process of separating from the push rod 52, the push rod 52 is always in contact with the receiving frame 2. Therefore, this method does not cause the push rod 52 to be in instantaneous contact with the receiving frame 2, causing the push rod 52 to be subjected to a large rigid impact.

[0069] like Figure 7 As shown, regarding the structure of the telescopic component 5, in this embodiment, a third optional specific implementation method is used, in which the telescopic component 5 is a flexible component, such as a medium-filled capsule 8. The specific medium of the medium-filled capsule 8 can be gas or liquid, and is arranged between the back of the receiving frame 2 and the main frame 1 or between the bottom of the receiving frame 2 and the main frame 1; one end of the medium-filled capsule 8 is fixedly connected to the main frame 1 as a fixed end, and the other end of the medium-filled capsule 8 is able to contact the receiving frame 2 as a movable end, and when the medium is filled in the medium-filled capsule 8, the medium-filled capsule 8 expands so that the free end pushes the receiving frame 2 to rotate outward from the main frame 1.

[0070] Specifically, the medium-filled capsule 8 is a gas medium capsule or a liquid medium capsule, and the specific medium capsule is selected according to actual conditions; the medium-filled capsule 8 is connected to a medium pump, such as an air pump, a hydraulic pump, etc., which can extract the medium from the medium-filled capsule 8 or infuse the medium into the medium-filled capsule 8.

[0071] It should be noted that, since the medium is gas or liquid and the telescopic component 5 itself is a flexible component, no rigid impact will be generated when the telescopic component 5 contacts the receiving frame 2 .

[0072] In this embodiment, the washing machine can be opened by adopting one or more combinations of the above three embodiments, that is, the receiving frame 2 rotates toward the outside of the main frame 1; when the washing machine is closed (the receiving frame 2 rotates toward the inside of the main frame 1), in order to avoid position interference of the telescopic component 5, the telescopic component 5 can be reset under the drive of the receiving frame 2.

[0073] Example 4

[0074] like Figure 3 、 Figure 4 、 Figure 7 As shown, based on any one of the implementation methods in Example 3, a specific implementation method that can be implemented is further proposed.

[0075] An optional embodiment is that when the receiving frame 2 is in the open position, the washing bin 3 is exposed outside the main frame 1; when the receiving frame 2 is in the closed position, the washing bin 3 is located inside the main frame 1; the opening and closing mechanism also includes a locking mechanism 9 for locking the receiving frame 2 in the closed position, and the locking mechanism 9 locks the receiving frame 2 in the closed position, restricts the movement of the receiving frame 2, and ensures that the relative position of the receiving frame 2 and the main frame 1 does not change.

[0076] In the above embodiment, for one implementation of the locking mechanism 9 , the locking mechanism 9 is a mechanical fixing structure.

[0077] In the above embodiment, for one implementation of the locking mechanism 9 , the locking mechanism 9 is an adsorption fixing structure.

[0078] In the above embodiment, for one embodiment of the locking mechanism 9 , the locking mechanism 9 is a mechanical fixing structure and an adsorption fixing structure.

[0079] Specifically, the mechanical fixing structure includes a lock core 92 and a lock hole 91, and the lock core 92 and the lock hole 91 are respectively arranged on the main frame 1 and the receiving frame 2. The lock hole 91 is a countersunk hole, which can place the lock core 92 to prevent the lock core 92 from passing through the lock hole 91 and failing to achieve the locking purpose; in this embodiment, the lock hole 91 is arranged on the main frame 1, and the lock core 92 is arranged on the receiving frame 2; or the lock hole 91 is arranged on the receiving frame 2, and the lock core 92 is arranged on the main frame 1; after the lock core 92 is inserted into the lock hole 91, the relative locking of the receiving frame 2 and the main frame 1 is achieved.

[0080] Specifically, the adsorption and fixing mechanism includes an adsorption part and an adsorbed part, and the adsorption part and the adsorbed part are respectively arranged on the main frame 1 and the receiving frame 2, and the adsorption part and / or the adsorbed part are one or more of a magnetic part or a negative pressure suction cup; in this embodiment, the adsorption part is installed on the main frame 1, and the adsorbed part is installed on the receiving frame 2; or the adsorption part is installed on the receiving frame 2, and the adsorbed part is installed on the main frame 1; the adsorption part and the adsorbed part are adsorbed on each other to achieve the locking of the relative position of the receiving frame 2 and the main frame 1.

[0081] It should be noted that the installation positions of the adsorption component and the adsorbed component should be close to the various joints (such as water inlet joints, drainage joints, etc.) on the main frame 1 and the receiving frame 2, so as to ensure that the relative position of the receiving frame 2 and the main frame 1 is stable while also ensuring that the joints on the receiving frame 2 and the main frame 1 are aligned accordingly; preferably, in this embodiment, the axes of the adsorption component and the adsorbed component are collinear with the axis of the joint, thereby improving the accuracy of the joint alignment.

[0082] Example 5

[0083] like Figure 3-Figure 5 As shown, based on Example 4, a specific implementation method that can be implemented is further proposed.

[0084] A feasible specific implementation method is to improve automation and determine whether the receiving frame 2 has accurately reached the closed position. A detection device 7 is provided on the telescopic component 5. The detection device 7 determines the position and / or state of the receiving frame 2 by detecting the position and / or state of the parts in the telescopic component 5.

[0085] For the telescopic component 5 being a hard component in Example 2, if the detection device 7 detects that the push rod 52 is in a position extending from the fixed seat 51, it means that the receiving frame 2 is located outside the main frame 1, the washing chamber 3 is located outside the main frame 1, and the washing machine is in the open state; if the detection device 7 detects that the push rod 52 is in a position retracted into the fixed seat 51, it means that the receiving frame 2 is located inside the main frame 1, and the washing chamber 3 is in the closed state.

[0086] More specifically, for the telescopic component 5 being a hard component, the detection device 7 can adopt a photoelectric detector, which has an emitter and a sensor, and the push rod 52 is between the emitter and the sensor. The emitter and the sensor are both fixed to the front end of the fixed seat 51 (that is, the position where the push rod 52 extends or retracts into the fixed seat 51) or on the main frame 1. When fixed on the main frame 1, the emitter and the sensor are both close to the position where the push rod 52 extends or retracts into the fixed seat 51; a baffle 53 is provided on the push rod 52. When the push rod 52 is fully retracted into the fixed seat 51, the baffle 53 is located between the emitter and the sensor, so that the baffle 53 can block the light signal between the emitter and the sensor, and the sensor does not receive the signal from the emitter, thereby determining that the receiving frame 2 is already in the closed position; conversely, when the sensor can receive the signal from the emitter, it determines that the push rod 52 is in the position extending out of the fixed seat 51, thereby determining that the receiving frame 2 is in the open position or other non-closed position.

[0087] A plurality of detection devices 7 can be provided on the fixing seat 51, which are respectively used to detect the movement of the push rod 52 to the maximum extension position, the first retracted position, and the second retracted position. The second retracted position is the maximum retracted position of the push rod 52. When the push rod 52 is retracted to the first retracted position, the locking mechanism 9 connects the receiving frame 2 with the telescopic assembly 5, and the docking holes such as the water inlet hole and the drainage hole on the receiving frame 2 are docked with the water inlet and drainage mechanism on the main frame 1. The push rod 52 drives the receiving frame 2 to continue to be retracted to the second retracted position, so that the docking holes on the receiving frame 2 are pressed and sealed with the water inlet and drainage mechanism on the main frame 1.

[0088] For the telescopic component 5 being the flexible component in Example 2, the detection device 7 may adopt a pressure sensor capable of detecting the internal pressure of the medium-filled sac 8. When the pressure sensor has a pressure signal, the medium-filled sac 8 contains pressure medium, thereby determining that the receiving frame 2 is in an open position or other non-closed position; conversely, when the pressure sensor has no pressure signal, it is determined that the receiving frame 2 is in a closed position.

[0089] In a feasible specific implementation manner, the detection device 7 is connected to the input end of the controller, and the output end of the controller is connected to the locking mechanism 9 so that the locking mechanism 9 can be automatically unlocked or locked, thereby improving the automatic performance and reducing the complexity of the user's operation.

[0090] Specifically, when the detection device 7 has no signal (for the photoelectric detector, the sensor does not receive the signal; for the pressure sensor, the pressure sensor has no pressure signal), it is determined that the receiving frame 2 is in the closed position, and the controller controls the locking mechanism 9 to automatically lock, thereby automatically locking the receiving frame 2 in the closed position; conversely, when the detection device 7 has a signal, it is determined that the receiving frame 2 needs to be opened or is in the open position or is moving toward the closed position, and the controller controls the locking mechanism 9 to remain in the open state, so as to prevent the locking mechanism 9 from restricting the outward rotation of the receiving frame 2 or the receiving frame 2 from entering the closed position.

[0091] More specifically, in this embodiment, in Example 4, when the locking mechanism 9 is a mechanical fixing structure, a solenoid valve lock can be selected. When the locking mechanism 9 is an adsorption fixing mechanism, an electromagnet, a negative pressure device, or the like can be selected as the locking mechanism 9.

[0092] Example 6

[0093] like Figure 3 , Figure 6 As shown, based on any one of Examples 1-5, a specific implementation method that can be implemented is further proposed.

[0094] An optional specific implementation method is that a damper 6 with a buffering effect is provided near the front end of the receiving frame 2, the fixed end of the damper 6 is connected to the main frame 1, and the movable end of the damper 6 can abut against the front end of the receiving frame 2; when the receiving frame 2 rotates at a speed close to the open position, the receiving frame 2 abuts against the damper 6 so that the receiving frame 2 is subjected to the reaction force of the damper 6, thereby causing the speed of the receiving frame 2 to gradually decrease, so as to ensure that when the receiving frame 2 enters the open position at a relatively small or almost zero speed, on the one hand, it avoids the front end of the receiving frame 2 from colliding with the main frame 1, thereby ensuring the service life of the receiving frame 2; on the other hand, it avoids the receiving frame 2 from reaching the open position too fast and causing injuries to the user.

[0095] On the basis of the above embodiment, an optional specific embodiment is provided, in which the fixed end of the damper 6 is a damping cylinder 61, and a connecting shaft 62 is provided on the damping cylinder 61. The fixed end of the damper 6 is rotatably connected to the main frame 1 through the connecting shaft 62, so that the damper 6 can rotate around the connecting shaft 62, thereby preventing motion interference between the damper 6 and the receiving frame 2; the movable end of the damper 6 is a telescopic rod 63, and the telescopic rod 63 is connected to the damping sliding connection of the damping cylinder 61, and there is a medium capable of generating a damping force between the telescopic rod 63 and the damping cylinder 61, which can be a sealed fluid medium (including a liquid medium and / or a gas medium), or a friction medium (such as a rubber layer, a friction pad) that can suppress the relative motion between the telescopic rod 63 and the damping cylinder 61, or an elastic medium (such as a spring 64) that can generate elastic deformation.

[0096] Specifically, when the receiving frame 2 contacts and squeezes the telescopic rod 63, the telescopic rod 63, under the action of the receiving frame 2, generates relative motion with the damping cylinder 61. The medium between the telescopic rod 63 and the damping cylinder 61 inhibits the movement of the telescopic rod 63, generating a damping force, thereby slowing the receiving frame 2. More specifically, when the medium is a gaseous medium, the relative motion between the telescopic rod 63 and the damping cylinder 61 causes the pressure of the fluid medium to change, disrupting the original pressure balance and generating a damping force. When the medium is a friction medium, the relative motion between the telescopic rod 63 and the damping cylinder 61 generates relative sliding friction, which acts as a damping force. When the medium is an elastic medium, the relative motion between the telescopic rod 63 and the damping cylinder 61 causes the elastic medium to deform, generating elastic potential energy, which acts as a damping force.

[0097] In the above embodiment, an optional specific embodiment is that a spring 64 is connected to the damping cylinder 61, one end of the spring 64 is connected to the damping cylinder 61, and the other end of the spring 64 is connected to the main frame 1, and the spring 64 resets the damper 6; specifically, since the receiving frame 2 rotates around the rotating shaft 4, when the receiving frame 2 contacts the telescopic rod 63, it will force the damper 6 to produce a rotational movement with the connecting shaft 62 as the rotation axis, and the damper 6 rotates to pull the spring 64, causing the spring 64 to undergo elastic deformation and have elastic potential energy. When the receiving frame 2 no longer applies pressure to the telescopic rod 63 of the damper 6, the elastic potential energy of the spring 64 is released, thereby resetting the damper 6 and preparing to produce a damping effect on the receiving frame 2 next time.

[0098] Example 7

[0099] like Figure 4 As shown, based on any one of Examples 1-6, a specific implementation method that can be implemented is further proposed.

[0100] In a feasible embodiment, an elastic member 10 is provided between the outer wall of the receiving frame 2 and the inner wall of the main frame 1. When the receiving frame 2 is completely within the main frame 1, the elastic member 10 is in a deformed state; that is, when the receiving frame 2 is in the closed position, the elastic member 10 has elastic potential energy. Specifically, in this embodiment, in order to reduce the internal space occupied by the telescopic assembly 5 of the main frame 1, the telescopic assembly 5 is actually relatively small. In this embodiment, the receiving frame 2 is merely pushed to give it an initial velocity, and the receiving frame 2 is no longer locked by the locking mechanism 9. The receiving frame 2 is in a free state, and the elastic potential energy of the elastic member 10 is released, continuing to push the receiving frame 2 to rotate outward, completing the opening of the washing machine.

[0101] Example 8

[0102] A method for opening and closing a washing machine, using the opening and closing mechanism disclosed in the above embodiment, such as Figure 1-Figure 7 As shown, the following steps are included:

[0103] S1: Turn on the washing machine; the locking mechanism 9 between the receiving frame 2 and the main frame 1 is unlocked. The method of unlocking the locking mechanism 9 is described in detail in Example 4. The telescopic assembly 5 works to push the receiving frame 2 to rotate toward the front side of the main frame 1 until the bottom of the front end of the receiving frame 2 abuts against the main frame 1, and the receiving frame 2 reaches the open position; the washing chamber 3 is located in the receiving frame 2 and moves with the receiving frame 2 to the open position;

[0104] S11: In step S1, the elastic member between the receiving frame 2 and the main frame 1 releases elastic potential energy, which acts on the receiving frame 2 to assist the receiving frame 2 in rotating toward the front side of the main frame 1. Due to the presence of the elastic member, the distance that the telescopic assembly 5 pushes the receiving frame 2 does not need to be large, and only needs to achieve the purpose of giving the receiving frame 2 an initial velocity and releasing the locking mechanism 9.

[0105] S2: When the washing tank 3 needs to be replaced, the washing tank 3 is taken out from the receiving frame 2 and another washing tank 3 is placed into the receiving frame 2 to complete the replacement of the washing tank 3;

[0106] S3: When the receiving frame 2 needs to be replaced, the rotating mechanism is disassembled, the receiving frame 2 is separated from the main frame 1, and then a new receiving frame 2 is installed to complete the replacement of the receiving frame 2;

[0107] In step S3, the telescopic assembly 5 is not connected to the receiving frame 2, which can reduce the number of parts that need to be disassembled when disassembling the receiving frame 2, thereby reducing the complexity of disassembly;

[0108] S4: Closing the washing machine; pushing the receiving frame 2 toward the rear side of the main frame 1, the receiving frame 2 enters the main frame 1 until the rear end of the receiving frame 2 abuts against the main frame 1, and the receiving frame 2 reaches the closed position; the washing chamber 3 moves to the closed position following the receiving frame 2; the washing machine is closed;

[0109] S41: During the process of pushing the receiving frame 2 to rotate toward the rear side of the main frame 1, the receiving frame 2 compresses the elastic member, and the elastic member stores elastic potential energy in preparation for the next start of the washing machine;

[0110] S42: After the receiving frame 2 reaches the closed position, the telescopic assembly 5 is driven to reset, preparing for the telescopic assembly 5 to push the receiving frame 2 next time;

[0111] S43: After the receiving frame 2 reaches the closed position, the locking mechanism 9 is locked. The specific process of locking the locking mechanism 9 is described in the relevant embodiment 4, and the relative position of the receiving frame 2 and the main frame 1 is fixed;

[0112] S44: If the locking mechanism 9 is set on the telescopic component 5, after the locking mechanism 9 locks the telescopic component 5 and the receiving frame 2, the telescopic component 5 works, pulling the receiving frame 2 to continue to move a short distance to the rear side of the main frame 1, and the interface on the washing bin 3 is docked with the joint in the main frame 1; or, if the locking mechanism 9 is not set on the telescopic component 5, the interface on the washing bin 3 is directly docked with the joint in the main frame 1.

[0113] In the above embodiment, the receiving frame 2 may be in the form of a flat plate, a frame assembled from multiple plate-like structures, or a barrel-shaped structure.

[0114] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
