Description

Technical Field

[0001] This application relates to a household appliance. In particular, it relates to a washing machine, dryer, or washer-dryer. Background Technology

[0002] Household appliances, especially washing machines, have doors for selectively closing or opening openings for cleaning or maintenance. To open and close, doors typically pivot about a pivot axis. With a horizontal pivot axis, as the door pivots towards the horizontal plane, the distance from the door's center of gravity to the pivot axis increases—that is, the lever arm of gravity increases—causing the door to spin faster and faster. This can lead to damage to the door's main body or pivoting structure, especially due to a sudden stop at the end of the pivoting process. Utility Model Content

[0003] The purpose of embodiments of this application is to provide an improved household appliance that enables effective damping of door pivoting through a damping structure, thereby preventing damage to the door body or pivoting structure.

[0004] According to a first aspect of this application, an embodiment of this application provides a household appliance, characterized in that the household appliance comprises:

[0005] A housing, wherein the housing is provided with a hinge seat;

[0006] A door, wherein the door is provided with a hinge and is pivotable relative to the housing about a pivot axis, the hinge and the hinge seat cooperate to form a pivot mating surface, and the pivot axis is substantially horizontal;

[0007] A damping structure includes a first damping portion disposed on the door and a second damping portion fixed relative to the housing. The first damping portion and the second damping portion cooperate to form a damping surface, which is capable of damping the pivoting of the door at least during the final stage of the door's pivoting toward the horizontal plane.

[0008] The damping surface and the pivoting mating surface are spaced apart in position.

[0009] By using a damping surface that provides damping at least during the final stage of the door's pivoting towards the horizontal plane, the door's speed during this final stage of pivoting can be effectively reduced, thereby preventing damage to the door body or the hinge joint between the door and the housing. Furthermore, by positioning the damping surface and the pivoting mating surface separately, the design of the damping surface can be simplified.

[0010] According to an optional embodiment of this application, the angle formed between the damping surface and the pivot axis is between 80 degrees and 90 degrees; and / or

[0011] The damping surface acts as a damper throughout the entire pivoting process of the door.

[0012] With an angle between 80 and 90 degrees, the damping surface can function over a wide range of door pivot angles. By acting as a damper throughout the pivoting process, the damping surface ensures that the door pivots smoothly towards the horizontal plane.

[0013] According to an optional embodiment of this application, the damping surface is radially outward relative to the pivoting mating surface with respect to the pivoting axis. This results in a larger lever arm of the damping force generated by the damping surface with respect to the pivoting axis, thereby producing a better damping effect and avoiding increased design difficulty for the interferometer and interferometer surface due to the need for a larger amount of interference.

[0014] According to an alternative embodiment of this application, the first damping portion and the second damping portion interfere with each other during pivoting about the pivot axis, thereby forming damping; and / or

[0015] One of the first damping part and the second damping part is configured as an interference body and the other is configured as an interference surface. As the door pivots, the interference body interacts with the interference surface.

[0016] Interference allows for simpler structural damping with cost advantages. Different interference quantities can be easily generated at different pivot angles using interferometric bodies and surfaces.

[0017] According to an optional embodiment of this application, the first damping portion is cylindrical, with its central axis parallel to the pivot axis, and the second damping portion is an arcuate surface extending circumferentially around the pivot axis. This simplifies the manufacturing of the damping portion and does not excessively hinder the pivoting of the door.

[0018] According to an optional embodiment of this application, the household appliance has an arc-shaped groove, the inner arc surface of the arc-shaped groove forms a second damping part, the outer arc surface of the arc-shaped groove has a notch, the first damping part can be inserted into the arc-shaped groove through the notch, and one end of the arc-shaped groove forms a stop structure that can limit the maximum pivot angle of the door to open.

[0019] The curved groove reliably guides the pivoting of the first damping section. The notch on the outer curved surface facilitates door installation. The stop structure prevents the door from touching the ground and, in particular, prevents damage to the decorative layer.

[0020] According to an optional embodiment of this application, the door has a first pivot angle relative to the housing and a second pivot angle different from the first pivot angle. At the first pivot angle, the first damping portion and the second damping portion have a first interference amount, and at the second pivot angle, the first damping portion and the second damping portion have a second interference amount different from the first interference amount. This allows for more flexible generation of suitable interference effects.

[0021] According to an optional embodiment of this application, the door is vertical in the closed state and adapted to be pivotally opened by tilting downwards. The household appliance is configured such that as the pivot angle of the door increases, the interference between the first damping portion and the second damping portion increases. This correspondingly counteracts the increasing torque of the door's weight, thereby allowing the door to open at a substantially uniform speed.

[0022] According to an optional embodiment of this application, the household appliance includes a fixing component that can be mounted on the housing, the fixing component integrating the hinge seat and the second damping portion. Thus, the manufacturing of the hinge seat and the second damping portion is separate from the manufacturing of the housing, and a new fixing component can be replaced if the hinge seat and the second damping portion are damaged.

[0023] According to an optional embodiment of this application, the housing has a mounting hole, and the fixing component has a snap-fit ​​structure adapted to snap into the mounting hole;

[0024] The fixing component has a square body, and the buckle structure includes two flanges located on the left and right sides of the square body and adapted to pass through the mounting hole and abut against the outer wall of the housing, and a stop located on the upper side of the square body and adapted to abut against the inner wall of the housing. The two flanges include a wider first flange and a narrower second flange.

[0025] The stop is integrated with a protrusion adapted to engage with a positioning hole in the housing to restrict the movement of the fixing component along the housing;

[0026] The stop has a groove to form a spring-loaded portion that supports the protrusion.

[0027] The snap-fit ​​structure allows for easy installation and securing of components. Flanges and stops ensure the components can be fixed in the front-to-back direction. Two flanges of different widths simplify installation and ensure a secure snap-fit. Protrusions allow the components to be fixed in directions perpendicular to the front-to-back direction. The spring-loaded design further reduces the difficulty of installing the components.

[0028] According to an optional embodiment of this application, the door includes a door panel, and a mounting arm is provided on the back of the door panel, wherein the hinge portion and the first damping portion are integrated into the mounting arm;

[0029] The first damping part is located on the side of the hinge part opposite to the door panel.

[0030] This simplifies the installation and manufacturing of doors.

[0031] According to an optional embodiment of this application, the household appliance is a washing machine, a dryer, or a washer-dryer;

[0032] When the door is closed, it covers the functional components of the household appliance.

[0033] The hinge is located on one side of the functional component, and the door is provided with one of a hook and a mating surface on the other side of the functional component. The household appliance has the other of the hook and the mating surface. The mating surface has a locking section corresponding to the closed state of the door and a releasing section corresponding to the open state of the door. In the closed state of the door, the hook is abutted by the locking section to lock the door. In the open state of the door, the hook corresponds to the releasing section and can pivot with the door.

[0034] The functional components are a drain outlet, a lint collection section, or a heat dissipation section.

[0035] The latches and mating surfaces allow the other side of the door to be locked even when closed, thereby reducing door vibration and noise when household appliances are in operation.

[0036] According to an optional embodiment of this application, the first damping portion and / or the second damping portion are non-rigid damping portions, so as to deform due to interference during pivoting.

[0037] According to an optional embodiment of this application, the door is disposed on the lower part of the user-facing front surface of the housing and includes a decorative layer disposed on the user-facing front surface, and:

[0038] The door is vertical in the closed state and is adapted to be pivoted open by tilting downwards; and / or

[0039] The front surface of the decorative layer has similar and / or identical and / or consistent characteristics with the front surface of its adjacent portion; and / or

[0040] The front surface of the decorative layer is on the same plane as the front surface of its adjacent portion; and / or

[0041] The decorative layer is made of at least one of the following materials: plastic, metal, glass, and sintered stone.

[0042] This makes household appliances more aesthetically pleasing, in particular. Attached Figure Description

[0065] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.

[0066] Figure 1 An example of a household appliance of this application is illustrated schematically.

[0067] like Figure 1 As shown, the household appliance includes:

[0068] Housing 1, wherein the housing 1 is provided with a hinge seat 60;

[0069] Door 2, which is provided with a hinge 20 and can pivot relative to the housing 1 about a pivot axis 21. The hinge 20 and the hinge seat 60 cooperate to form a pivot mating surface 80. The pivot axis 21 is basically horizontal.

[0070] A damping structure 30 includes a first damping portion 31 disposed on the door 2 and a second damping portion 32 fixed relative to the housing 1. The first damping portion 31 and the second damping portion 32 cooperate to form a damping surface 81. The damping surface 81 is capable of damping the pivoting of the door 2 at least during the final stage of the pivoting of the door 2 toward the horizontal plane 82.

[0071] The damping surface 81 and the pivoting mating surface 80 are spaced apart in position.

[0072] exist Figure 1 In the figure, the pivot axis 21 is perpendicular to the plane and is shown as a black dot. As the door 2 pivots toward the horizontal plane 82, the distance between the center of gravity of the door 2 and the pivot axis 21 increases, thus the acceleration effect of the door 2's gravity on its rotation becomes stronger. In this application, by using a damping surface 81 that acts as a damper at least during the final stage of the pivoting of the door 2 toward the horizontal plane 82, the speed of the door 2 at the end of the pivoting phase can be effectively reduced, thereby particularly preventing damage to the main body of the door 2 or the hinge portion 20 of the door 2 and the hinge seat 60 of the housing 1. Furthermore, by setting the damping surface 81 and the pivot mating surface 80 to be spaced apart in position, the design of the damping surface 81 can be facilitated.

[0073] The phrase "the housing 1 is provided with a hinge seat 60" specifically covers at least two situations: the hinge seat 60 is integral with the housing 1, or a portion thereof; or the hinge seat 60 is independent of the housing 1 and can be mounted and fixed to the housing 1. The word "provided" appearing elsewhere in the context should be understood similarly. Figure 1 In this example, the hinge seat 60 is integrated into the housing 1, while the hinge portion 20 is integrated into the door 2. The hinge seat 60 includes, for example, a hinge hole or a hinge shaft, while the hinge portion 20 correspondingly includes a hinge shaft or a hinge hole.

[0074] "The pivot axis 21 is basically horizontal" is to be understood in particular as: the angle between the pivot axis 21 and the horizontal plane 82 does not exceed twenty degrees, and in particular does not exceed ten degrees, and also includes strict horizontality.

[0075] "At least in the final stage of the pivoting of door 2 toward horizontal plane 82" specifically refers to the last tenth, especially the last fifth, particularly the last quarter, or for example the last third of the entire pivoting journey of door 2 toward horizontal plane 82.

[0076] According to an exemplary embodiment, such as Figure 1 As shown, the first damping part 31 and the second damping part 32 interfere 33 during pivoting around the pivot axis 21, thereby forming damping. Through interference 33, damping can be structurally simpler to form and has cost advantages. Figure 1 In the diagram, the boundary of the region where the second damping part 32 interferes with the first damping part 31 is shown by a dashed line.

[0077] According to an exemplary embodiment, the first damping portion 31 and / or the second damping portion 32 are non-rigid damping portions, so as to deform due to interference 33 during pivoting. The first damping portion 31 and the second damping portion 32 are, in particular, plastic. However, other materials, such as rubber or foam, are also conceivable.

[0078] According to an exemplary embodiment, such as Figure 1 As shown, one of the first damping portion 31 and the second damping portion 32 is configured as an interferometer 34 and the other as an interference surface 35. As the door 2 pivots, the interferometer 34 interacts with the interference surface 35. In this embodiment, the interference surface 35 forms a damping surface 81. Furthermore, as the door 2 pivots, the interferometer 34 contacts and interferes with different portions of the interference surface 35, particularly at approximately the same locations. This allows for the convenient design of different interference amounts at different pivoting angles of the door 2. Figure 1 In the first damping part 31, the interference surface 35 is formed, and the second damping part 32, the interference body 34 is formed.

[0079] According to an exemplary embodiment, such as Figure 1 As shown, with respect to the pivot axis 21, the damping surface 81 is radially outward relative to the pivot mating surface 80. Therefore, the lever arm of the damping force generated by the damping surface 81 with respect to the pivot axis 21 is larger, resulting in better damping and avoiding increased design difficulty for the interferometer 34 and interferometer surface 35 due to the need for a larger amount of interference.

[0080] Figure 2 Another example of the household appliance of this application is illustrated schematically. Only the portion of the household appliance relevant to this application is shown here, where the door 2 and the front panel 10 of the housing 1 are shown. The household appliance is exemplary of a washing machine, particularly a front-loading washing machine. However, the household appliance may also be a dryer or washer-dryer, or other types of household appliances such as a refrigerator, oven, or microwave oven.

[0081] Figure 3 Schematic illustration Figure 2 An example of a rear view.

[0082] According to an exemplary embodiment, such as Figure 2 and Figure 3 As shown, the door 2, when closed, covers the functional components 70 of the household appliance. Figure 3 In this example, the functional component 70 is a drain outlet. However, the door 2 can also be other doors of a household appliance, and the functional component 70 can also be a lint collection section or a heat dissipation section.

[0083] Figure 4 Schematic illustration Figure 2 An example of a partially enlarged sectional view of a household appliance. This is shown... Figure 2 The area of ​​damping and hinges for the household appliances used in door 2.

[0084] According to an exemplary embodiment, such as Figure 2 and Figure 4As shown, the door 2 is disposed on the lower part of the user-facing front surface of the housing 1 and includes a decorative layer 24 disposed on the user-facing front surface, and:

[0085] The door 2 is vertical in the closed state and is adapted to be pivoted open by tilting downwards; and / or

[0086] The front surface of the decorative layer 24 has similar and / or identical and / or consistent characteristics with the front surface of its adjacent portion; and / or

[0087] The front surface of the decorative layer 24 is on the same plane as the front surface of its adjacent portion; and / or

[0088] The decorative layer 24 is made of at least one of plastic, metal, glass, and sintered stone.

[0089] According to an exemplary embodiment, such as Figure 4 As shown, the first damping part 31 is cylindrical, and its central axis 310 is parallel to the pivot axis 21. The second damping part 32 is an arc surface extending circumferentially around the pivot axis 21. This allows for the convenient manufacture of the damping structure 30 without excessively hindering the pivoting of the door 2. Here, in conjunction with... Figure 1 Conversely, the first damping part 31 is an interference body 34, while the second damping part 32 is an interference surface 35. Instead of a cylindrical shape, the first damping part 31 can also be other shapes, such as a sphere, trapezoid, or triangle.

[0090] See Figure 4 In this example, the first damping part 31 and the second damping part 32 interfere 33, particularly perpendicular to the pivot axis 21. Alternatively, it may be conceivable that the interference 33 between the first damping part 31 and the second damping part 32 is parallel to or inclined to the pivot axis 21.

[0091] According to an exemplary embodiment, such as Figure 3 and Figure 4 As shown, the household appliance includes a mounting component 6 that can be installed on the housing 1. The mounting component 6 integrates the hinge seat 60 and the second damping part 32. This design allows the manufacturing of the hinge seat 60 and the second damping part 32 to be separate from the manufacturing of the housing 1, and allows for replacement of the mounting component 6 if the hinge seat 60 or the second damping part 32 is damaged. Alternatively, the hinge seat 60 and / or the second damping part 32 can be directly integrated into the housing 1.

[0092] Figure 5 An example of the fixed component 6 is shown in magnification.

[0093] According to an exemplary embodiment, such as Figure 5As shown, the household appliance has an arc-shaped groove 4. The inner arc surface 41 of the arc-shaped groove 4 forms the second damping part 32. The outer arc surface 42 of the arc-shaped groove 4 has a notch 43. The first damping part 31 can be inserted into the arc-shaped groove 4 through the notch 43. One end 45 of the arc-shaped groove 4 forms a stop structure 44 that can limit the maximum pivot angle of the door 2. The arc-shaped groove 4 reliably guides the pivoting of the first damping part 31. The notch 43 on the outer arc surface 42 facilitates the installation of the door 2. The stop structure 44 prevents the door 2 from touching the ground and, in particular, prevents damage to the decorative layer 24.

[0094] Figure 6 Schematic illustration Figure 2 An example of a damping structure 30 for a household appliance.

[0095] According to an exemplary embodiment, such as Figure 6 As shown, the angle 50 formed between the damping surface 81 and the pivot axis 21 is between 80 and 90 degrees. Therefore, the damping surface 81 can function over a large range of pivot angles of the door 2.

[0096] According to an exemplary embodiment, see Figure 6 The damping surface 81 acts as a damper throughout the pivoting process of the door 2. Thus, the door 2 pivots smoothly toward the horizontal plane 82. Alternatively, it can be conceivable that the damping surface 81 only functions from the middle stage of the pivoting process of the door 2 toward the horizontal plane 82 or only at the end stage.

[0097] According to an exemplary embodiment, such as Figure 6 As shown, the door 2 has a first pivot angle 51 relative to the housing 1 and a second pivot angle 52 different from the first pivot angle 51. At the first pivot angle 51, the first damping part 31 and the second damping part 32 have a first interference amount 331. At the second pivot angle 52, the first damping part 31 and the second damping part 32 have a second interference amount 332 different from the first interference amount 331. This allows for more flexible generation of suitable interference effects. Figure 6 In the diagram, the distance from the center of the first damping section 31 to the pivot axis 21 is constant. The first damping section 31 and the gate 2 are shown as dashed lines at the first pivot angle 51 and as dotted lines at the second pivot angle 52.

[0098] According to an exemplary embodiment, such as Figure 6As shown, the door 2 is vertical in the closed state and is adapted to be pivotally opened by flipping downwards. The household appliance is configured such that as the pivot angle of the door 2 increases, the interference 33 between the first damping part 31 and the second damping part 32 increases. Figure 6 In the closed state, the first damping part 31 and the door 2 are shown in solid lines. To increase the interference 33, along the opening direction of the door 2, or in other words... Figure 6 As the clockwise direction increases, the distance from the point on the second damping part 32 to the pivot axis 21 increases.

[0099] Figure 7 Schematic illustration Figure 2 An example of a portion of the housing 1 of a household appliance.

[0100] According to an exemplary embodiment, such as Figure 4 , Figure 5 and Figure 7 As shown, the housing 1 has a mounting hole 11, and the fixing component 6 has a snap-fit ​​structure adapted to snap into the mounting hole 11. The snap-fit ​​structure allows for convenient installation of the fixing component 6.

[0101] For example, the fixing component 6 has a square body 63. The snap-fit ​​structure includes two flanges 64 located on the left and right sides of the square body 63 and adapted to pass through the mounting hole 11 and abut against the outer wall 13 of the housing 1, and a stop 62 located on the upper side of the square body 63 and adapted to abut against the inner wall 14 of the housing 1. The two flanges 64 include a wider first flange 641 and a narrower second flange 642. The flanges 64 and the stop 62 allow the fixing component 6 to be fixed in the front-back direction. The two flanges 64 of different widths simplify installation and achieve a good snap-fit.

[0102] For example, the stop 62 integrates a protrusion 620 adapted to engage with the positioning hole 12 of the housing 1 to restrict the movement of the fixing member 6 along the housing 1. The protrusion 620 allows the fixing member 6 to be fixed in other directions perpendicular to the front-back direction.

[0103] For example, the stop 62 has a groove 621 to form a spring-loaded portion 622 that supports the protrusion 620. The spring-loaded portion 622 can advantageously reduce the installation difficulty of the fixing member 6.

[0104] Figure 8 Schematic illustration Figure 3 In this section, fixing component 6 has been removed.

[0106] Figure 10 Schematic illustration Figure 9 A local example of gate 2.

[0107] According to an exemplary embodiment, such as Figure 9 and Figure 10 As shown, the door 2 includes a door panel 22, and a mounting arm 23 is provided on the back of the door panel 22. The hinge portion 20 and the first damping portion 31 are integrated into the mounting arm 23. Figure 10 As shown, the first damping portion 31 is located, in particular, on the side of the hinge portion 20 facing away from the door panel 22. Exemplarily, a mounting arm 23 has two hinge portions 20 and two second damping portions 31.

[0108] Figure 11 Schematic illustration Figure 8 A portion of it. This is shown here. Figure 8 The bottom left corner.

[0109] Figure 12 yes Figure 11 A partially enlarged sectional view.

[0110] According to an exemplary embodiment, such as Figure 8 , Figure 11 and Figure 12 As shown, the hinge 20 is located on one side of the functional component 70. The door 2 is provided with one of a hook 25 and a mating surface 71 on the other side of the functional component 70. The household appliance has the other of the hook 25 and mating surface 71. The mating surface 71 has a locking section 72 corresponding to the closed state of the door 2 and a releasing section 73 corresponding to the open state of the door 2. In the closed state of the door 2, the hook 25 is pressed against the locking section 72 to lock the door 2. In the open state of the door 2, the hook 25 corresponds to the releasing section 73 and can pivot with the door 2. Through the hook 25 and the mating surface 71, the other side of the door 2 can also be locked in the closed state, thereby reducing the vibration of the door 2 and the resulting noise when the household appliance is operating.

[0111] In the example shown, a hook 25 is provided on the door 2, while a mating surface 71 is provided on the housing 1. Obviously, it is also possible to reverse this and provide a mating surface 71 on the door 2, while providing a hook 25 on the housing 1.

[0112] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this application, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this application are intended for illustrative purposes and not for limitation, unless otherwise stated. In practice, multiple features may be combined with each other as needed and where technically feasible. Various substitutions, modifications, and alterations are also conceived without departing from the spirit and scope of this application.
