[0034] In the structure of the current washing machine or washing and drying integrated machine, the detachable installation mode of the inner drum has become a common design paradigm, and its core demand is to realize the convenient cleaning function of the inner drum to improve the user's use experience and maintenance efficiency. However, the existing inner drum fixing technology mainly relies on the bolt fixing mechanism. Although the bolt fixing relies on its reliable connection performance, it meets the stability requirements of the inner drum installation to a certain extent, but it exposes significant limitations in the disassembly link. Since the operation process must rely on special tools to complete the disassembly of the bolts, ordinary users face a high operation threshold, which greatly limits the autonomy and convenience of the inner drum cleaning.

[0035] In order to overcome the above technical problems, as shown in Figures 1-9 The present embodiment provides an inner drum installation structure of a washing and drying integrated machine, comprising:

[0036] A main shaft 1 is provided with a connecting flat head 11 at one end;

[0037] The inner cylinder 2 is sleeved at the bottom of the connecting head 11, and the rotation degree of the inner cylinder 2 relative to the connecting head 11 is locked; wherein the inner cylinder 2 comprises an inner cylinder main body 21 and an inner cylinder chassis 22 fixedly connected to the bottom of the inner cylinder main body 21 and capable of providing stable support for the bottom of the inner cylinder main body 21; a limiting shoulder is formed on the main shaft 1 at the bottom of the connecting head 11, and the limiting shoulder is capable of abutting against the inner cylinder chassis 22 to form a limit to restrict the axial installation distance of the inner cylinder 2;

[0038] The locking assembly 3 comprises a locking seat 31, a locking slider 32, a spring 33 and an unlocking block 34, the locking seat 31 is provided with a mounting through cavity 311, the locking slider 32 is slidably installed in the mounting through cavity 311, and the two ends of the spring 33 are connected with the locking slider 32 and the mounting through cavity 311 respectively; the side wall of the connecting head 11 is provided with a locking groove 111 matched with the locking slider 32, when mounted, the connecting head 11 extends into the mounting through cavity 311, and under the elastic force of the spring 33, the locking slider 32 is clamped and locked with the locking groove 111, and the locking seat 31 locks the inner cylinder 2 on the connecting head 11; the unlocking block 34 is in transmission connection with the locking slider 32, when disassembled, the locking slider 32 is pushed to slide by pressing the unlocking block 34, so that the locking slider 32 is unlocked by being separated from the locking groove 111.

[0039] In specific implementation, the influence of the centrifugal force of the locking slider 32 on the rotation of the locking assembly 3 needs to be considered, that is, the spring 33 needs to have a large enough elastic force to resist the centrifugal force of the locking slider 32, so as to ensure that the locking slider 32 can always be stably clamped with the locking groove 111 during work.

[0040] In specific disassembly, the user can manually press the unlocking block 34, the unlocking block 34 actively pushes the locking slider 32 to slide, so that the locking slider 32 is separated from the clamping of the locking groove 111, and then the user can take out the entire locking assembly 3, and after taking out the locking assembly 3, the inner cylinder 2 can be further taken out. Conversely, when mounted, the inner cylinder 2 is sleeved on the connecting head 11, and then the locking assembly 3 is mounted to lock the inner cylinder 2, and when the locking assembly 3 is specifically mounted, the locking slider 32 can be first slid to an unlocking position by pressing the unlocking block 34, then the mounting through cavity 311 of the locking seat 31 is aligned with the connecting head 11 and is installed, and then the unlocking block 34 is released, and the locking slider 32 is automatically pushed to be clamped with the locking groove 111 by the elastic force of the spring 33.

[0041] In the embodiment, when installed, the connecting flat head 11 extends into the installation through cavity 311, and the locking slider 32 is locked and clamped with the lock slot 111 under the elastic force of the spring 33, and the locking seat 31 locks the inner drum 2 on the connecting flat head 11. This design enables reliable connection between the inner drum 2 and the main shaft 1, ensures the stability of the inner drum 2 during the operation of the washing machine or the washing and drying all-in-one machine, and meets the stability requirement of the installation of the inner drum 2.

[0042] The existing inner drum 2 fixing technology relies on bolt fixing, and special tools are required for disassembly, which has a high operation threshold for ordinary users. However, in the inner drum installation structure of the embodiment, the locking slider 32 can be pushed to slide by pressing the unlocking block 34, so that the locking slider 32 is unlocked by being separated from the lock slot 111. Therefore, special tools are not required, and ordinary users can easily complete the disassembly operation of the inner drum 2, thereby greatly improving the autonomy and convenience of the cleaning of the inner drum 2.

[0043] In an embodiment, referring to Figure 5 , the locking assembly 3 further comprises a protective cover 35, which is detachably covered on the locking seat 31, and the unlocking block 34 is covered by the protective cover 35.

[0044] The protective cover 35 covers the unlocking block 34, which can avoid the accidental unlocking of the inner drum 2 due to the accidental touching of the unlocking block 34 during the normal use of the washing machine or the washing and drying all-in-one machine. This helps to ensure the stability of the inner drum 2 during the operation of the machine, reduces the failure or safety hazard caused by the misoperation, and ensures the smooth progress of the washing process. In addition, the protective cover 35 can also prevent the unlocking block 34 from falling out of the installation through cavity 311 during the operation.

[0045] Before disassembly, the user needs to manually disassemble the protective cover 35 to perform the unlocking and disassembly. After installation, the protective cover 35 is covered and reset.

[0046] In an embodiment, the unlocking block 34 is movably installed at the top region in the installation through cavity 311, the top surface of the unlocking block 34 is exposed from the top side of the installation through cavity 311, and the unlocking block 34 can be unlocked by pressing the top surface of the unlocking block 34 towards the main shaft 1.

[0047] In this embodiment, the top surface of the unlocking block 34 is exposed on the top side of the installation through cavity 311, the user can directly see the unlocking position and operation direction, and the unlocking block 34 can be unlocked by pressing the top surface of the unlocking block 34 towards the main shaft 1. The operation is simple and intuitive, reduces the difficulty of user operation, and improves the user experience.

[0048] In an embodiment, in combination with Figure 8 , the side of the locking seat 31 is provided with a hand holding slot 312, and the locking assembly 3 can be pulled out through the hand holding slot 312 when the unlocking block 34 is pressed to be unlocked.

[0049] In operation, the user can hold the two sides of the hand buckle groove 312 with four fingers of both hands, and press the unlocking block 34 at the top with two thumbs. After pressing the unlocking block 34, the four fingers lift the locking seat 31 to achieve the purpose of easily and quickly taking out the entire locking assembly 3.

[0050] The user holds the two sides of the hand buckle groove 312 with four fingers of both hands, and presses the unlocking block 34 at the top with two thumbs. After pressing the unlocking block 34, the four fingers lift the locking seat 31. This operation method conforms to ergonomics, and the unlocking and taking out actions are completed by both hands in cooperation, which is convenient to operate and improves the operation efficiency. The design of the hand buckle groove 312 and the unlocking block 34 makes the force point clear during operation, the four fingers hold the hand buckle groove 312 to provide stable gripping force, and the two thumbs press the unlocking block 34 to provide convenient and moderate force, which is easier to unlock. In the case of being equipped with a spring 33 with greater elasticity, the user can also unlock more easily. Therefore, this design allows the spring 33 with greater elasticity to be equipped to improve the stability in the locked state.

[0051] In an embodiment, the protective cover 35 is threadedly connected with the locking seat 31, and the peripheral part of the protective cover 35 is provided with a finger groove.

[0052] The threaded connection structure is stable, can effectively prevent the protective cover 35 from being accidentally loosened and falling off due to vibration or external force during normal operation of the washing and drying integrated machine, ensures the stability of the inner drum mounting structure, and avoids faults or safety hazards caused by loosening of the protective cover 35. The threaded connection provides stable connection force, the finger groove facilitates the user to grip and rotate the protective cover 35, and the protective cover 35 is convenient to disassemble and assemble without the need for additional tools, thereby improving the use experience.

[0053] In an embodiment, the inner side of the protective cover 35 is provided with a foam pad 36, and the foam pad 36 is used to contact the unlocking block 34.

[0054] The foam pad 36 is located between the protective cover 35 and the unlocking block 34, and the softness of the foam pad 36 can reduce the vibration of the unlocking block 34, thereby avoiding the problem of noise caused by the impact between the unlocking block 34 and the protective cover 35 during work.

[0055] In an embodiment, in combination with Figure 5 and Figure 9 , the locking slider 32 includes a sliding plate 321 and a clamping tongue 322. The sliding plate 321 is slidably installed in the mounting through cavity 311, the clamping tongue 322 protrudes from the side of the sliding plate 321 facing the connecting flat head 11, and the clamping tongue 322 is adapted to be matched and locked with the locking slot 111. The spring 33 is connected with the sliding plate 321, and the unlocking block 34 is in transmission connection with the sliding plate 321.

[0056] The clamping tongue 322 protrudes from the side of the sliding plate 321 facing the connecting flat head 11 and is locked with the locking groove 111 on the connecting flat head 11. This design makes the cooperation between the locking sliding block 32 and the locking groove 111 more accurate, and the clamping tongue 322 can be accurately inserted into the locking groove 111, ensuring that the inner cylinder 2 will not loosen or displace during operation, and providing stable locking effect. The sliding plate 321 serves as the supporting structure of the clamping tongue 322, and its sliding installation in the installation through cavity 311 provides good support for the entire locking sliding block 32 under stress, enabling it to withstand greater locking force and improve locking strength. The presence of the sliding plate 321 enables the locking sliding block 32 to cooperate more stably with the unlocking block 34 to be driven to slide by the unlocking block 34.

[0057] Preferably, to improve the stability of the locking sliding block 32, a guide rail 313 is arranged in the installation through cavity 311 of the locking seat 31, and a guide groove 323 is arranged on the side wall of the locking sliding block 32. The cooperation between the guide rail 313 and the guide groove 323 can guide the lateral sliding of the locking sliding block 32, ensuring that the locking sliding block 32 can slide stably when being pushed by the unlocking block 34.

[0058] In an embodiment, the locking seat 31 is provided with two symmetrical locking sliding blocks 32, and the unlocking block 34 is arranged in an inverted trapezoidal shape. The two sides of the unlocking block 34 form guide inclined surfaces respectively abutting the top of the two sliding plates 321. When the unlocking block 34 is pressed, it pushes the locking sliding block 32 to slide laterally through the guide inclined surfaces, so that the clamping tongue 322 is disengaged from the locking groove 111 to unlock.

[0059] The two symmetrical locking sliding blocks 32 can bear force evenly when locking, ensuring that the inner cylinder 2 bears balanced force and improving the stability of locking. When unlocking, the unlocking block 34 pushes the two sliding blocks to slide laterally through the guide inclined surfaces, and the action is synchronized and balanced, avoiding unlocking failure caused by unilateral force and improving unlocking reliability. The unlocking block 34 is in an inverted trapezoidal shape, and the guide inclined surfaces are formed on its two sides. The design of the guide inclined surfaces of the inverted trapezoidal unlocking block 34 conforms to the principle of mechanics, and can convert vertical force into horizontal thrust when pressed, reducing the force required for unlocking and making the operation more labor-saving.

[0060] In an embodiment, the top surface of the clamping tongue 322 is arranged as a first inclined surface 3221, and the top wall of the locking groove 111 is correspondingly arranged as a second inclined surface. During the process of the clamping tongue 322 penetrating into the locking groove 111, the first inclined surface 3221 cooperates with the second inclined surface to push against the locking seat 31 and press the inner cylinder 2 axially.

[0061] The cooperation of the first inclined surface 3221 and the second inclined surface provides guidance for the clamping tongue 322 to accurately align with the lock slot 111, especially when the inner cylinder 2 is installed close to the locking position, it can automatically correct slight deviations and ensure accurate insertion. The smooth transition characteristics of the inclined surface make the contact between the clamping tongue 322 and the lock slot 111 more smooth, reduce the jamming, ensure the smoothness of the locking process, and improve the user experience. The cooperation of the inclined surface makes the clamping tongue 322 push the locking seat 31 to axially compress the inner cylinder 2 when it is deeply inserted into the lock slot 111, increases the friction and pre-tightening force, makes the connection between the inner cylinder 2 and the main shaft 1 more firm, improves the locking strength, and ensures stable operation.

[0062] In an embodiment, each of the sliding plates 321 is connected with a plurality of matrix-distributed springs 33 on the side away from the clamping tongue 322.

[0063] The matrix distribution of the plurality of springs 33 provides uniform and strong elastic force, so that the clamping tongue 322 tightly cooperates with the lock slot 111, prevents the inner cylinder 2 from loosening during operation, and improves the locking stability.
