Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and particularly relates to a laundry tub fixing structure and a washing machine. Background Art

[0002] The laundry tub of a current washing machine includes an outer tub and an inner tub structure. The inner tub is driven by a motor and can rotate during operation to provide a driving force for washing; the outer tub is fixed, provides support for the inner tub, and at the same time provides a closed cavity to store water. During the operation of the inner tub, vibrations will be transmitted to the outer tub. Therefore, in order to maintain the stability of the washing machine, the existing outer tub is generally installed in the washing machine frame through structures such as springs and elastic telescopic cylinders, and the springs and elastic telescopic cylinders are used to absorb the vibrations during the operation of the outer tub. In a washing machine, the outer tub actually belongs to a movable structure. During the factory transportation process of the washing machine, if it encounters relatively large vibrations, the laundry tub will vibrate more violently, and there is a risk that the internal structures of the laundry tub will collide and be damaged with each other. Therefore, when the existing washing machine leaves the factory, transportation bolts are usually used to completely lock the laundry tub in the frame, and the transportation bolts can be removed during installation for normal use.

[0003] The transportation bolts only play their functional roles during the transportation process of the washing machine. Therefore, after the transportation bolts are installed and removed, users generally can only discard them. Even if the transportation bolts are put away, they may be forgotten due to the passage of time. When users need to move or relocate the washing machine, they usually directly transfer the washing machine without fixing the laundry tub because they cannot find the transportation bolts. There is a risk of damage to the internal structures of the laundry tub due to mutual collision during this process. Summary of the Utility Model

[0004] The purpose of the embodiments of the present utility model is to provide a laundry tub fixing structure and a washing machine, which can solve the above problems existing in the prior art.

[0005] To achieve the above object, the present application adopts the following technical solutions:

[0006] On the one hand, a laundry tub fixing structure is provided, including:

The locking member includes two oppositely arranged ball head stud pins and a locking spring installed between the two ball head stud pins. The ball heads of the two ball head stud pins respectively extend outside the pin cylinder through the two through holes. Locking holes are provided on the side wall of the positioning jack on the positioning column. The locking spring is used to push out the two ball head stud pins so that the two ball head stud pins are inserted into the locking holes to limit the relative movement in the axial direction between the positioning column and the fixing pin.

[0012] Optionally, an anti-detachment tail plate is provided at one end of the ball head stud pin close to the locking spring. The size of the anti-detachment surrounding plate is larger than the aperture of the locking hole. The anti-detachment tail plate can prevent the ball head stud pin from detaching from the through hole.

[0013] Optionally, an unlocking plate is further provided inside the pin cylinder between the anti-detachment tail plate and the ball head end cap. The unlocking plate is provided with a V-shaped groove facing the anti-detachment tail plate. The control rope is connected to the unlocking plate. By pulling the unlocking plate through the control rope, the anti-detachment tail plate can be slid into the V-shaped groove, so that the two ball head stud pins approach each other and detach from the locking holes to achieve unlocking. At the same time, the control rope can push the ball head stud pins and the fixing pin away from the positioning jack through the unlocking plate to achieve unlocking.

[0014] Optionally, the support cylinder includes a base part and an installation part connected to the top side of the base part. The installation part is provided with an installation cavity for installing the top-out spring and the fixing pin. The base part is provided with a rope through hole communicating with the installation cavity. The control rope extends into the installation cavity through the rope through hole to be connected to the unlocking plate.

[0015] Optionally, a pull ring is connected to the end of the control rope far from the fixing pin.

[0016] Optionally, it further includes a washing machine housing, and the rack is installed inside the washing machine housing; the washing machine housing includes a main housing and a rear decorative cover. A rear inner cover is installed on the back side of the rack to enclose the structure inside the rack. A rope passing hole is provided on the rear inner cover, and the control rope extends outside the rear inner cover through the rope passing hole; the rear decorative cover is covered on the back side of the main housing to cover the rear inner cover.

[0017] Optionally, the outer wall of the rear inner cover is provided with a first hook and a second hook. When the control rope pulls the fixing pin to unlock, the hand ring can be hung on the first hook for fixation; when the fixing pin is inserted into the positioning jack for locking, the hand ring can be hung on the second hook for fixation.

[0018] On the other hand, a washing machine is provided, including the above-mentioned laundry tub fixing structure.

[0019] The beneficial effects of this application are as follows: The utility model provides a laundry tub fixing structure and a washing machine. A positioning post with a positioning jack is provided on the outer wall of the laundry tub, and a reusable fixing component is provided inside the rack. Before transporting the washing machine, the laundry tub can be locked by using the fixing component to provide protection. When installing the washing machine, the fixing component can be directly unlocked. Since the fixing component in this solution is directly fixed in the rack, it still remains stationary inside the washing machine after unlocking, and the user does not need to consider the problem of separately storing it after removal. Therefore, when the washing machine still needs to be moved after use, the fixing component can be released again to lock the laundry tub, thereby protecting the laundry tub.

[0020] The specific structure of the fixing component in this solution includes a support cylinder, a fixing pin, a top spring, a control rope and other structures. When the laundry tub needs to be locked, the fixing pin is released, and under the elastic force of the top spring, the fixing pin can be automatically ejected to a position where it is inserted and matched with the positioning post to achieve locking; when unlocking is required, only the control rope needs to be pulled to drive the fixing pin to disengage from the positioning jack. The control rope in this solution extends outside the rack. Therefore, when performing the unlocking operation, there is no need to disassemble the rack, nor is it necessary to use auxiliary tools. Only the end of the control rope needs to be simply pulled manually. Therefore, the fixing component in this solution has the advantages of simple and fast unlocking and locking operations, which is convenient for inexperienced users to complete the operation.

[0031] To make the technical problems solved by the present application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0032] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0034] The washing drum of the current washing machine includes an outer drum and an inner drum structure. The inner drum is driven by a motor and can rotate during operation to provide the driving force for washing; the outer drum is fixed, providing support for the inner drum and at the same time providing a closed cavity to store water. During the working process, the inner drum will transmit vibrations to the outer drum. Therefore, in order to maintain the stability of the washing machine, the existing outer drum is generally installed in the washing machine frame through structures such as springs and elastic telescopic cylinders, and the springs and elastic telescopic cylinders are used to absorb the vibrations of the outer drum during operation. In a washing machine, the outer drum actually belongs to a movable structure. During the transportation of the washing machine from the factory, if it encounters relatively large vibrations, the washing drum will vibrate violently, and there is a risk that the internal structures of the washing drum will collide and be damaged with each other. Therefore, when the existing washing machines leave the factory, transportation bolts are usually used to completely lock the washing drum in the frame, and the transportation bolts can be removed during installation for normal use.

[0035] The transportation bolts only play their functional roles during the transportation of the washing machine. Therefore, after the transportation bolts are installed and removed, users generally can only discard them. Even if the transportation bolts are put away, they may be forgotten due to the passage of time. When users need to move or relocate the washing machine, they usually directly transport the washing machine without fixing the washing drum because they cannot find the transportation bolts, and there is a risk of damage to the internal structures of the washing drum due to mutual collision during this process.

[0036] To overcome the above technical problems, referring to Figure 1-7 , this embodiment provides a washing drum fixing structure, including a frame 3, a washing drum 1 and a fixing component 2. A positioning column 11 with a positioning jack 111 is provided on the outer wall of the washing drum 1, and a reusable fixing component 2 is provided inside the frame 3. Before transporting the washing machine, the fixing component 2 can be used to lock the washing drum 1 to provide protection. When installing the washing machine, the fixing component 2 can be directly unlocked. Since the fixing component 2 in this solution is directly fixed in the frame 3, it still remains in the washing machine without moving after being unlocked, and users do not need to consider the problem of separately storing it after removal. Therefore, when the washing machine still needs to be moved after use, the fixing component 2 can be released again to lock the washing drum 1, so as to protect the washing drum 1.

[0037] In the specific solution of the fixing structure of the washing drum in this embodiment, the washing drum 1 is installed in the frame 3. A positioning post 11 is provided on the outer wall of the washing drum 1, and a positioning jack 111 is provided at the center of the positioning post 11. The fixing assembly 2 includes a support cylinder 21, a fixing pin 22, a top spring 23, and a control rope 24. The support cylinder 21 is fixed in the frame 3. The fixing pin 22 is telescopically installed in the support cylinder 21. The top spring 23 is installed in the support cylinder 21 and abuts against the fixing pin 22. The top spring 23 is used to push out the fixing pin 22 so that the fixing pin 22 is inserted into the positioning jack 111 to lock the washing drum 1. One end of the control rope 24 is connected to the fixing pin 22, and the other end extends outside the frame 3. The fixing pin 22 can be pulled through the control rope 24 to disengage from the positioning jack 111 to unlock.

[0038] The structure of the fixing assembly 2 in this solution specifically includes a support cylinder 21, a fixing pin 22, a top spring 23, and a control rope 24, etc. When it is necessary to lock the washing drum 1, release the fixing pin 22, and under the elastic force of the top spring 23, the fixing pin 22 can be automatically pushed out to the position where it is inserted and matched with the positioning post 11 to achieve locking. When unlocking is required, just pull the control rope 24 to drive the fixing pin 22 to disengage from the positioning jack 111. The control rope 24 in this solution extends outside the frame 3. Therefore, when performing the unlocking operation, there is no need to disassemble the frame 3, nor is it necessary to use auxiliary tools. Just simply manually pull the end of the control rope 24. Therefore, the fixing assembly 2 in this solution has the advantages of simple and fast unlocking and locking operations, which is convenient for inexperienced users to complete the operation.

[0039] To improve the reliability of fixing, preferably, multiple groups of fixing assemblies 2 are provided, and multiple corresponding positioning posts 11 are provided on the washing drum 1. When locking, multiple groups of fixing assemblies 2 can be used to lock the washing drum 1. Using the multi-point positioning method is beneficial to improving the reliability of fixing.

[0040] In one embodiment, referring to Figure 4 , the fixing pin 22 includes a pin cylinder 221 and a ball head end cap 222 connected to the end of the pin cylinder 221. The ball head end cap 222 is located at the end where the fixing pin 22 is inserted into the positioning jack 111.

[0041] The design of the ball head end cap 222 enables the fixing pin 22 to have better adaptability when inserted into the positioning jack 111. Due to the spherical surface of the ball head end cap 222, it can better contact the inner wall of the positioning jack 111, reducing the mismatch problems caused by manufacturing tolerances or assembly errors. This design improves the positioning accuracy and stability of the fixing pin 22 during the locking process.

[0042] In one embodiment, two coaxial through holes 2211 are provided on the side wall of the pin cylinder 221. A locking member 25 is installed in the pin cylinder 221. The locking member 25 includes two oppositely arranged ball-headed pins 251 and a locking spring 252 installed between the two ball-headed pins 251. The ball heads of the two ball-headed pins 251 respectively extend outside the pin cylinder 221 through the two through holes 2211. A locking hole 112 is provided on the side wall of the positioning jack 111 on the positioning column 11. The locking spring 252 is used to push the two ball-headed pins 251 out so that the two ball-headed pins 251 are inserted into the locking hole 112 to limit the relative movement in the axial direction between the positioning column 11 and the fixing pin 22.

[0043] In addition to the basic locking achieved by inserting the fixing pin 22 into the positioning jack 111 through the ball head end cap 222, the cooperation between the ball-headed pin 251 and the locking hole 112 is added as a second layer of locking. This dual-locking mechanism greatly improves the stability of the washing tub 1 during transportation and reduces the relative movement caused by vibration or impact.

[0044] It should be noted that although the locking member 25 is provided in this solution to lock the fixing pin 22 and the positioning column 11, the fixing pin 22 cannot be locked with the support cylinder 21. Therefore, even when the ejecting spring 23 exerts an elastic force, when the force is large enough, there is a possibility of relative axial movement between the fixing pin 22 and the support cylinder 21. Therefore, when the external force is large enough, the washing tub 1 may vibrate relative to the support cylinder 21 and the frame 3. To improve the reliability of fixing the washing tub 1, preferably, the ejecting spring 23 is a spring with a high elastic modulus, so that it can provide a greater elastic force to the fixing pin 22 to improve the stability of the washing tub 1. In addition, the washing tub 1 can also be fixed in multiple directions and at multiple points by setting multiple sets of fixing components 2 that expand and contract in different directions to strengthen the fixing of the washing tub 1.

[0045] In one embodiment, an anti-disengagement tail plate 2511 is provided at one end of the ball-headed pin 251 close to the locking spring 252. The size of the anti-disengagement surrounding plate is larger than the aperture of the locking hole 112. The anti-disengagement tail plate 2511 can limit the ball-headed pin 251 from disengaging from the through hole 2211.

[0046] The size of the anti-disengagement tail plate 2511 is designed to be larger than the aperture of the locking hole 112, which means that when the ball-headed pin 251 is pushed outside the through hole 2211 by the locking spring 252 and inserted into the locking hole 112, the anti-disengagement tail plate 2511 will play a blocking role to prevent the ball-headed pin 251 from completely falling out of the through hole 2211 when subjected to an external force. This design enhances the stability and reliability of the fixing structure.

[0047] In one embodiment, referring to Figure 5, an unlocking plate 26 is further provided in the pin cylinder 221 between the anti - detachment tail plate 2511 and the ball - head end cap 222. The unlocking plate 26 is provided with a V - shaped groove 261 facing the anti - detachment tail plate 2511. The control rope 24 is connected to the unlocking plate 26. By pulling the unlocking plate 26 through the control rope 24, the anti - detachment tail plate 2511 can be slid into the V - shaped groove 261, so that the two ball - head pin cylinders 251 approach each other and disengage from the locking hole 112 to achieve unlocking. At the same time, the control rope 24 can push the ball - head pin cylinder 251 and the fixed pin 22 through the unlocking plate 26 to disengage from the positioning jack 111 to achieve unlocking.

[0048] In the above - mentioned embodiment, an unlocking plate 26 is added in the pin cylinder 221. The unlocking plate 26 is connected to the control rope 24 through the V - shaped groove 261, realizing the dual unlocking function of the ball - head pin cylinder 251 and the fixed pin 22. The user only needs to pull the control rope 24, then the unlocking plate 26 can push the anti - detachment tail plate 2511 to slide into the V - shaped groove 261, so that the ball - head pin cylinder 251 disengages from the locking hole 112 and at the same time pushes the fixed pin 22 to disengage from the positioning jack 111, completing one - key unlocking. This design simplifies the unlocking operation, improves the unlocking efficiency and stability, and at the same time enhances the user experience and safety.

[0049] In one embodiment, the support cylinder 21 includes a base portion 212 and an installation portion 211 connected to the top side of the base portion 212. The installation portion 211 is provided with an installation cavity for installing the ejecting spring 23 and the fixed pin 22. The base portion 212 is provided with a rope - passing hole 2121 communicating with the installation cavity. The control rope 24 extends into the installation cavity through the rope - passing hole 2121 to be connected to the unlocking plate 26.

[0050] The base portion 212 serves as a support foundation, while the installation portion 211 is located on its top side and is specifically used for installing the ejecting spring 23 and the fixed pin 22. An installation cavity is provided inside the installation portion 211, providing an installation space for these components. It is worth noting that the base portion 212 is also cleverly designed with a rope - passing hole 2121, enabling the control rope 24 to smoothly pass through the base portion 212 and enter the installation cavity to be connected to the unlocking plate 26.

[0051] In one embodiment, a pull - ring 241 is connected to one end of the control rope 24 away from the fixed pin 22.

[0052] The addition of the pull - ring 241 enables the user to apply force more easily when pulling the control rope 24, without directly holding the slender control rope 24, thus avoiding the risk of hand discomfort or slipping.

[0053] In one embodiment, refer to Figure 1, further comprising a washing machine housing 4, wherein the frame 3 is installed inside the washing machine housing 4; the washing machine housing 4 includes a main housing 41 and a rear decorative cover 42, a rear inner cover 31 is installed on the back side of the frame 3 to enclose the structure inside the frame 3, a rope passing hole is provided on the rear inner cover 31, and the control rope 24 extends outside the rear inner cover 31 through the rope passing hole; the rear decorative cover 42 is covered on the back side of the main housing 41 to cover the rear inner cover 31.

[0054] The frame 3 is installed inside the washing machine housing 4 to serve as a foundation for supporting and fixing other components. The washing machine housing 4 includes two parts, namely a main housing 41 and a rear decorative cover 42. The main housing 41 constitutes the main appearance of the washing machine, while the rear decorative cover 42 is used to cover and beautify the structure on the back side of the frame 3. In order to enclose the structure inside the frame 3, a rear inner cover 31 is specially installed on the back side of the frame 3, and a rope passing hole is provided thereon so that the control rope 24 can smoothly extend outside the rear inner cover 31. When performing the unlocking and locking operations, the user only needs to open the rear decorative cover 42, and then can operate the internal fixing pin 22 by pulling the pull ring 241 connected to the control rope 24, which is both convenient and practical.

[0055] In one embodiment, a first hook 311 and a second hook 312 are provided on the outer wall of the rear inner cover 31. When the control rope 24 pulls the fixing pin 22 to unlock, the pull ring 241 can be hung on the first hook 311 for fixation; when the fixing pin 22 is inserted into the positioning jack 111 for locking, the pull ring 241 can be hung on the second hook 312 for fixation.

[0056] After the control rope 24 needs to be pulled to unlock the fixing pin 22, the user can hang the pull ring 241 on the first hook 311, so as to maintain the tension of the control rope 24 and enable the fixing component 2 in the installed washing machine to remain in the unlocked state for a long time. When it is necessary to lock the washing tub 1 during transportation, after the fixing pin 22 has been successfully inserted into the positioning jack 111 and locked, the user can hang the pull ring 241 on the second hook 312 to fix the control rope 24 and prevent it from swinging randomly or winding around other components.

[0057] On the other hand, a washing machine is provided, including the above-mentioned washing tub fixing structure.

[0058] Similarly, based on the drum fixing structure of this embodiment, before the washing machine of this embodiment is transported, the fixing component 2 can be used to lock the drum 1 to provide protection. When installing the washing machine, the fixing component 2 can be directly unlocked. Since the fixing component 2 in this solution is directly fixed in the frame 3, it still remains stationary inside the washing machine after unlocking, and the user does not need to consider the problem of separately storing it after removal. Therefore, when the washing machine still needs to be moved after use, the fixing component 2 can be released again to lock the drum 1, thereby protecting the drum 1.
