Description

Technical Field

[0001] This invention belongs to the field of washing devices and their components, specifically, it relates to an outer tub cover for a washing device, an outer tub cover for a washing device with a tension spring assembly, and a washing device. Background Technology

[0002] Some top-loading washing machines, due to their special structure and programs, require a buffer device to reduce or slow down the shaking of the outer tub module and reduce vibration noise during the washing or spin-drying process.

[0003] During the washing and spin-drying processes, the washing machine's drum module wobbles from side to side and also moves up and down. Therefore, the components that match the outer drum lid, namely the aforementioned cushioning device, need to have both vertical and horizontal freedom of movement. Otherwise, the cushioning device may easily be damaged due to excessive localized stress.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an outer tub cover for a washing device, which can provide a connecting device to connect an external buffer device so that the tub module can be protected during operation.

[0006] A second object of the present invention is to provide an outer tub cover for a washing device with a tension spring assembly.

[0007] A third objective of the present invention is to provide a washing apparatus.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] The washing device has an outer tub cover with several connecting devices. Each connecting device includes a semi-open receiving cavity. The top wall of the receiving cavity and the side wall on the same side of the outer tub cover as the connecting device in the left and right directions have through openings.

[0010] By installing several connecting devices on the outer barrel lid, and symmetrically arranging these devices in pairs, a buffer device can be connected to the outer barrel lid to provide cushioning protection for the barrel module when it shakes. For convenient and secure connection with the buffer device, each connecting device on the outer barrel lid includes a semi-open receiving cavity. This semi-open cavity allows the connecting end of the buffer device to be inserted into the cavity through its opening, facilitating the connection between the connecting device and the buffer device. A through-hole is provided on the top wall of the receiving cavity and on the side wall of the outer barrel lid on the same left and right sides as the connecting device. This through-hole design connects the inside and outside of the receiving cavity. This structure prevents the connecting end of the buffer device from detaching from the receiving cavity after it has been inserted. Since the buffer device needs to connect not only to the connecting device but also to the hanger rod in the hanger rod assembly of the washing device, it must extend outside the receiving cavity. Therefore, through-holes are provided on the top wall of the receiving cavity and on the side wall of the connecting device on the same side as the outer tub lid in the left and right directions, allowing the buffer device to be installed and extend out of the receiving cavity of the connecting device. Because the buffer device connected to the connecting device needs to connect to the hanger rod of the hanger rod assembly, in order to facilitate a normal and convenient connection of the outer tub lid, the connecting device on the left side of the outer tub lid connects to the hanger rod on the left side of the outer tub lid. Therefore, through-holes are provided on the left side wall of the connecting device on the left side of the outer tub lid, allowing the buffer device to extend out of the receiving cavity through this through-hole and connect to the hanger rod on the left side of the outer tub lid. Furthermore, the top of this through-hole on the left side wall is connected to the through-hole on the top wall of the receiving cavity, and the through-hole on the top wall of the receiving cavity is connected left and right. Similarly, the connecting device on the right side of the outer barrel cover is connected to the hanging rod on the right side of the outer barrel cover. Therefore, a through-hole is provided on the right side wall of the connecting device on the right side of the outer barrel cover so that the buffer device can extend out of the receiving cavity through this through-hole and connect with the hanging rod on the right side of the outer barrel cover. Furthermore, the top of this through-hole on the right side wall is connected to the through-hole on the top wall of the receiving cavity.

[0011] Furthermore, the receiving cavity of the connecting device has an insertion port on its top or on the side wall opposite to the connecting device in the left-right direction of the outer barrel cover. The size of the insertion port in the front-back direction of the outer barrel cover is larger than the size of the notch in this direction.

[0012] This insertion port provides an inlet for the buffer device to be inserted into the receiving cavity. The insertion port can be located at the top of the receiving cavity, or it can be located on the side wall opposite the connecting device in the left-right direction of the outer lid. Specifically, the insertion port could be located on the right side wall of the connecting device on the left side of the outer lid. Based on the weight and tension of the buffer device, this structure prevents the buffer device from detaching from the insertion port. Furthermore, the insertion port's dimension along the front-back direction of the outer lid is larger than the dimension of the notch in this direction. This is so that after the connecting end of the buffer device is inserted into the receiving cavity through the insertion port, the side wall forming the notch can prevent the connecting end of the buffer device from detaching from the receiving cavity. Since the insertion port is for inserting the connecting end of the buffer device, its dimension along the front-back direction of the outer lid should match the dimension of the connecting end of the buffer device in this direction. The side wall forming the notch is to prevent the connecting end of the buffer device from detaching from the receiving cavity; therefore, the dimension of the insertion port along the front-back direction of the outer lid is larger than the dimension of the notch in this direction.

[0013] Furthermore, when the receiving cavity of the connecting device is provided with an insertion port at its top, the insertion port is located at one end of the top, and this end is away from the side wall of the connecting device on the same side as the left and right direction of the outer barrel cover.

[0014] To prevent the connecting end of the buffer device from coming out of the receiving cavity from the insertion port when it shakes, the insertion port is located at the top end, and this end is away from the side wall on the same side as the connecting device in the left and right direction of the outer barrel cover. That is, the insertion port of the connecting device on the right side of the outer barrel cover is located at the top left end of the receiving cavity, and the insertion port of the connecting device on the left side of the outer barrel cover is located at the top right end of the receiving cavity.

[0015] Furthermore, the receiving cavity is located on the outer periphery of the outer barrel cover, and the outer side wall of the receiving cavity in the front-rear direction is provided with reinforcing ribs, which extend and connect to the outer periphery of the outer barrel cover.

[0016] Since the buffer device and the outer tub cover need to be pulled relative to each other after they are connected, in order to facilitate the overall installation of the outer tub cover on the washing device and make the connecting device structure stronger, a reinforcing rib is provided on the outer periphery of the outer tub cover in the front and rear directions of the receiving cavity, and the reinforcing rib extends to connect to the outer periphery of the outer tub cover.

[0017] The present invention also proposes a washing device outer tub cover with a tension spring assembly, including the washing device outer tub cover described above, and further including a tension spring assembly, one end of which is movably confined in a receiving cavity, and the tension spring assembly extends from a notch on the side wall of the outer tub cover on the same side as the connecting device in the left-right direction.

[0018] Furthermore, the end of the tension spring assembly located in the receiving cavity includes a rotating shaft, a limiting plate, and a first hook of the tension spring. The first hook is hooked onto the rotating shaft and can move freely in the axial and radial directions relative to the rotating shaft. Limiting plates are provided at both ends of the rotating shaft to prevent the first hook from disengaging from the rotating shaft.

[0019] The dimension of the pivot along the front and rear direction of the outer barrel cover is smaller than the dimension of the insertion opening in that direction, but larger than the dimension of the notch in that direction.

[0020] Furthermore, the other end of the tension spring assembly located outside the receiving cavity includes a connector, which is connected to the second hook of the tension spring, and the connector is provided with a through hole.

[0021] Furthermore, the lateral dimension of the receiving cavity of the connecting device is larger than the dimension of the limiting plate in this direction; there is a gap between the limiting plate and the rotating shaft, allowing them to rotate relative to each other.

[0022] The present invention also proposes a washing device, which is provided with the aforementioned washing device outer tub cover with a tension spring assembly, and the washing device hanging rod passes through the through hole of the connector.

[0023] Furthermore, after installation, the tension spring assembly has a preload, and the tension spring assembly is located at one end in the receiving cavity of the connecting device, with its pivot located below the top wall of the receiving cavity.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] This invention relates to a washing device outer tub cover, a washing device outer tub cover with a tension spring assembly, and a washing device. The outer tub cover includes several connecting devices, each with a semi-open receiving cavity. The top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction have through-holes. By providing several connecting devices on the outer tub cover, and symmetrically arranged in pairs, a buffer device can be connected to the outer tub cover to provide cushioning protection for the tub module when it shakes. The semi-open receiving cavity allows the connecting end of the buffer device to be inserted into the receiving cavity through its opening. The through-holes on the top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction allow the buffer device to be installed and extend out of the receiving cavity of the connecting device. The top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction prevent the connecting end of the buffer device from falling out of the receiving cavity.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting this invention.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Combination Figures 1 to 7 As shown, the outer tub cover 3 of the washing device of the present invention has several connecting devices 6. Each connecting device 6 includes a semi-open receiving cavity 64. The top wall of the receiving cavity 64 and the side wall on the same side as the connecting device 6 in the left-right direction of the outer tub cover 3 have through openings.

[0043] By providing several connecting devices 6 on the outer barrel cover 3, and symmetrically arranged in pairs, the outer barrel cover 3 can be connected to a buffer device to provide cushioning protection for the barrel module when it shakes. For convenient and secure connection with the buffer device, the connecting devices 6 on the outer barrel cover 3 include semi-open receiving cavities 64. These semi-open cavities allow the connecting end of the buffer device to be inserted into the cavity through its opening, thus combining the connecting device 6 with the buffer device. A through-hole is provided on the top wall of the receiving cavity 64 and on the side wall of the outer barrel cover 3 on the same left-right direction as the connecting device 6. This through-hole design connects the inside and outside of the receiving cavity 64. This structure prevents the connecting end of the buffer device from detaching from the receiving cavity 64 after it has been inserted. Since the buffer device needs to be connected not only to the connecting device 6 but also to the hanger in the hanger assembly 4 of the washing device, the buffer device needs to extend out of the receiving cavity 64. Therefore, a through-hole is provided on the top wall of the receiving cavity 64 and on the side wall of the connecting device 6 on the same side as the outer tub cover 3 in the left and right directions, so that the buffer device can be installed and extend out of the receiving cavity 64 of the connecting device 6. Since the buffer device connected to the connecting device 6 needs to be connected to the hanger of the hanger assembly 4, in order to enable the outer tub cover 3 to be connected normally and conveniently, the connecting device 6 on the left side of the outer tub cover 3 is connected to the hanger on the left side of the outer tub cover 3. Therefore, a through-hole is provided on the left side wall of the connecting device 6 on the left side of the outer tub cover 3 so that the buffer device can extend out of the receiving cavity 64 through this through-hole and connect to the hanger on the left side of the outer tub cover 3. The top of this through-hole on the left side wall is connected to the through-hole on the top wall of the receiving cavity 64, and the through-hole on the top wall of the receiving cavity 64 is connected from left to right. Similarly, the connecting device 6 on the right side of the outer barrel cover 3 is connected to the hanging rod on the right side of the outer barrel cover 3. Therefore, a through-hole is provided on the right side wall of the connecting device 6 on the right side of the outer barrel cover 3 so that the buffer device can extend out of the receiving cavity 64 through this through-hole and connect with the hanging rod on the right side of the outer barrel cover 3. Furthermore, the top of this through-hole on the right side wall is connected to the through-hole on the top wall of the receiving cavity 64.

[0044] The receiving cavity 64 of the connecting device 6 has an insertion port 61 on its top or on the side wall opposite to the connecting device 6 in the left-right direction of the outer lid 3. The insertion port 61 is larger in the front-back direction of the outer lid 3 than the notch in this direction. This insertion port 61 provides an entrance for the buffer device to be inserted into the receiving cavity 64. The insertion port 61 can be located at the top of the receiving cavity 64 or on the side wall opposite to the connecting device 6 in the left-right direction of the outer lid 3. That is, the connecting device 6 is located on the left side of the outer lid 3, and the insertion port 61 is located on the right side wall of the connecting device 6. Based on the weight and tension of the buffer device, this structure can prevent the buffer device from coming out of the insertion port 61. In addition, the insertion port 61 is larger in the front-back direction of the outer lid 3 than the notch in this direction so that after the connecting end of the buffer device is inserted into the receiving cavity 64 through the insertion port 61, the side wall forming the notch can block and restrict the connecting end of the buffer device from coming out of the receiving cavity 64. Since the insertion port 61 is for inserting the connecting end of the buffer device, the size of the insertion port 61 in the front-back direction along the outer barrel cover 3 should match the size of the connecting end of the buffer device in this direction. The side wall forming the notch is to prevent the connecting end of the buffer device from coming out of the receiving cavity 64. Therefore, the size of the insertion port 61 in the front-back direction along the outer barrel cover 3 is larger than the size of the notch in this direction.

[0045] When the receiving cavity 64 of the connecting device 6 has an insertion port 61 at its top, the insertion port 61 is located at one top end, and this end is away from the side wall of the connecting device 6 on the same side as the outer lid 3 in the left-right direction. This structure is adopted in this embodiment. In order to prevent the connecting end of the buffer device from coming out of the receiving cavity 64 from the insertion port 61 when shaking, the insertion port 61 is located at one top end, and this end is away from the side wall of the connecting device 6 on the same side as the outer lid 3 in the left-right direction. That is, the insertion port 61 of the connecting device 6 provided on the right side of the outer lid 3 is located at the top left end of the receiving cavity 64, and the insertion port 61 of the connecting device 6 provided on the left side of the outer lid 3 is located at the top right end of the receiving cavity 64.

[0046] The receiving cavity 64 is located on the outer periphery of the outer tub cover 3. Reinforcing ribs 65 are provided on the outer side walls of the receiving cavity 64 in the front-rear direction, extending and connecting to the outer periphery of the outer tub cover 3. Since the buffer device is connected to the connecting device 6 of the outer tub cover 3, the two will pull against each other. Therefore, to facilitate the overall installation of the outer tub cover 3 on the washing device and to strengthen the structure of the connecting device 6, the receiving cavity 64 is located on the outer periphery of the outer tub cover 3, and reinforcing ribs 65 are provided on the outer side walls of the receiving cavity 64 in the front-rear direction, extending and connecting to the outer periphery of the outer tub cover 3.

[0047] The present invention also proposes a washing device outer tub cover 3 with a tension spring assembly 5, including the washing device outer tub cover 3 described above, and further including a tension spring assembly 5, one end of which is movably confined in a receiving cavity 64, and the tension spring assembly 5 extends from a notch on the side wall of the outer tub cover 3 on the same side as the connecting device 6 in the left-right direction.

[0048] The end of the tension spring assembly 5 located in the receiving cavity 64 includes a rotating shaft 52, a limiting piece 53, and a first hook 511 of the tension spring. The first hook 511 is hooked onto the rotating shaft 52 and can move freely in the axial and radial directions relative to the rotating shaft 52. Limiting pieces 53 are provided at both ends of the rotating shaft 52 to prevent the first hook 511 from disengaging from the rotating shaft 52. The dimension of the rotating shaft 52 in the front-back direction along the outer barrel cover 3 is smaller than the dimension of the insertion opening 61 in this direction, but larger than the dimension of the notch in this direction.

[0049] The other end of the tension spring assembly 5 located outside the receiving cavity 64 includes a connector 54, which is connected to the second hook 512 of the tension spring, and the connector 54 is provided with a through hole 541.

[0050] The accommodating cavity 64 of the connecting device 6 has a larger dimension in the left-right direction than the dimension of the limiting piece 53 in this direction; there is a gap between the limiting piece 53 and the rotating shaft 52, allowing them to rotate relative to each other.

[0051] The tension spring assemblies 5, serving as a buffer device, are typically arranged in 4 groups (one tension spring assembly 5 hanging on each boom) or 8 groups (two tension spring assemblies 5 hanging on each boom), symmetrically arranged in pairs. A configuration of 4 groups is preferred. Figure 1 As shown. The straight-insertion connecting device 6 on the outer barrel cover 3, which matches the tension spring assembly 5, is also set in 4 or 8 sets, arranged symmetrically in pairs.

[0052] During the washing and spin-drying processes of a washing device such as a washing machine, the tub module sways left and right while also moving up and down. Therefore, the tension spring assembly 5, which matches the outer tub cover 3, needs to have both vertical and horizontal freedom. Otherwise, it is easy for the tension spring assembly 5 to be damaged due to excessive local stress.

[0053] Combination Figure 8 , 9 As shown, one end of the tension spring 51 of the tension spring assembly 5 is connected to the rotating shaft 52 via a first hook 511. The first hook 511 needs to be designed with no opening or an opening smaller than the diameter of the rotating shaft 52 to prevent the first hook 511 from falling radially off the rotating shaft 52. In this embodiment, the first hook 511 with an opening smaller than the diameter of the rotating shaft 52 is used.

[0054] A certain gap is reserved between the first hook 511 of the tension spring 51 and the rotating shaft 52. The first hook 511 can move freely in the axial and radial directions relative to the rotating shaft 52. The first hook 511 can rotate freely up and down, and also has a certain degree of freedom in the left and right directions, and can also swing left and right. After the tension spring assembly 5 is installed, its tension spring has a certain initial tension to prevent the rotating shaft 52 from coming out of the insertion port 61 of the receiving cavity 64 of the connecting device 6 during the operation of the washing machine.

[0055] The connecting device 6 is provided with a shaft 52 receiving cavity 64. The top part of the receiving cavity 64 is open to facilitate the insertion of the shaft 52. The other part of the top of the receiving cavity 64 is provided with a top wall with a notch. The two sides of the top wall forming the notch can act as baffles 62 to prevent the shaft 52 from coming out of the top of the receiving cavity 64 and to block the shaft 52 inside the receiving cavity 64.

[0056] The receiving cavity 64 has a through-hole groove 63 on the side wall of the outer barrel cover 3 on the same side as the connecting device 6 in the left-right direction, which is combined with the connecting device 6. Figure 2 , 4 As shown in Figures 5, 6, and 7, the sidewalls of the notch are designed to allow the tension spring to extend out of the receiving cavity 64 from this side, and the sidewalls on both sides of the notch can prevent the rotating shaft 52 of the tension spring assembly 5 from dislodging out of the receiving cavity 64 from this side.

[0057] The tension spring assembly 5 is located at the other end of the receiving cavity 64 via a connector 54, which also includes a connecting shaft. The second hook 512 of the tension spring is connected to this connecting shaft, and the second hook 512 needs to be without an opening or with an opening smaller than the diameter of the connecting shaft to prevent the second hook 512 from radially detaching from the connecting shaft. A certain gap is reserved between the second hook 512 of the tension spring and the connecting shaft, allowing the second hook 512 to move freely axially and radially relative to the connecting shaft. The second hook 512 can rotate freely up and down, and also has a certain degree of freedom in the left and right directions, and can also swing left and right. Limiting devices are provided on both sides of the second hook 512 along the axial direction of the connecting shaft to prevent the second hook 512 from axially detaching from the connecting shaft.

[0058] The connecting device 6 of the outer barrel cover 3 can connect to the tension spring assembly 5, which improves the operability, processability, and reliability of installing the tension spring assembly 5, and makes the installation operation simple and quick.

[0059] The present invention also proposes a washing device, which is a top-opening impeller washing device, including an inner tub 2 and an outer tub 1. The top of the outer tub 1 is provided with the aforementioned washing device outer tub cover 3 with tension spring assembly 5, and the hanging rod of the washing device passes through the through hole 541 of the connector 54.

[0060] After installation, the tension spring assembly 5 has a preload. The tension spring assembly 5 is located at one end in the receiving cavity 64 of the connecting device 6, and its pivot 52 is located below the top wall of the receiving cavity 64, thereby preventing the tension spring assembly 5 from coming out of the receiving cavity 64.

[0061] When the washing machine is running, the tub module consisting of the inner tub and the outer tub shakes. The tension spring assembly connects to the connecting device on the outer tub cover. The tension spring assembly can move in the receiving cavity of the connecting device, and the tension spring assembly itself has a high degree of freedom, so it can protect the tub module without damaging the tension spring assembly.

[0062] This invention relates to a washing device outer tub cover, a washing device outer tub cover with a tension spring assembly, and a washing device. The outer tub cover includes several connecting devices, each with a semi-open receiving cavity. The top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction have through-holes. By providing several connecting devices on the outer tub cover, and symmetrically arranged in pairs, a buffer device can be connected to the outer tub cover to provide cushioning protection for the tub module when it shakes. The semi-open receiving cavity allows the connecting end of the buffer device to be inserted into the receiving cavity through its opening. The through-holes on the top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction allow the buffer device to be installed and extend out of the receiving cavity of the connecting device. The top wall of the receiving cavity and the side wall of the connecting device on the same side of the outer tub cover in the left-right direction prevent the connecting end of the buffer device from falling out of the receiving cavity.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention and its technical solutions. The implementation schemes in the above embodiments can also be further combined or replaced.
