[0033] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] Reference below Figure 1-Figure 5 A household appliance 100 according to an embodiment of the present invention is described.

[0035] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, a household appliance 100 includes a body 10, a door 12 and an elastic member.

[0036] The body 10 has a working cavity and an access opening 11 located at the front side of the working cavity. For example, the household appliance 100 may be a washing machine. When the household appliance 100 is a drum washing machine, the working cavity is a washing cavity, and clothes can be put into or taken out of the working cavity through the access opening 11.

[0037] Door 12 is rotatably connected to body 10 to open or close access opening 11. For example, door 12 is rotatable between a first position 14 and a second position 15. In first position 14, door 12 closes access opening 11, and in second position 15, door 12 opens access opening 11. An elastic member, one end of which is connected to body 10 and the other end of which is connected to door 12, is used to drive door 12 to rotate and open access opening 11. This allows door 12 to automatically open by being driven by the elastic force of the elastic member.

[0038] For example, the elastic member is a torsion spring, which is sleeved on the rotating shaft 33 of the door body 12. One end of the elastic member is connected to the body 10, and the other end of the elastic member is connected to the door body 12. When the door body 12 is in a state of closing the access port 11, the elastic member is compressed; when the user needs to open the door body 12, the elastic member bounces the door body 12 open to open the access port 11.

[0039] For example, the household appliance 100 may also include a door lock and an unlocking device. When the door body 12 is in a state of closing the access port 11, the door body 12 is locked by the door lock, and the elastic part is compressed at this time; when the user needs to open the door body 12, the door lock is unlocked by the unlocking device, and the elastic part bounces the door body 12 open to open the access port 11.

[0040] Among them, the rotation axis of the door body 12 is the door body rotation axis 13, and the door body rotation axis 13 is located on one side of the access opening 11 along the left-right direction. For example, the door body rotation axis 13 is located on the left or right side of the access opening 11, and the door body rotation axis 13 extends from bottom to top toward the rear. Since the rotation axis of the door body 12 extends from bottom to top toward the rear, during the opening process of the door body 12, the self-weight of the door body 12 has a component force for rotating the door body 12 in the direction of closing the access opening 11. The component force for rotating the door body 12 in the direction of closing the access opening 11 due to the self-weight of the door body 12 is smaller than the elastic force of the elastic member on the door body 12, which can slow down the automatic opening process of the door body 12 and prevent the door body 12 from being ejected too wide when opening, causing the door body 12 to collide with people or other devices near the household appliance 100.

[0041] In addition, by extending the door body rotation axis 13 in an inclined direction from bottom to top toward the rear, the shortest distance between the door body 12 and the ground can gradually increase and the door body 12 can gradually rise during the process of the door body 12 changing from a state where the access port 11 is closed to a state where the access port 11 is open, thereby reducing the collision between the door body 12 and lower parts near the household appliance 100, and also reducing the collision between the door body 12 and the edge of the body 10 when closing the door.

[0042] According to the household appliance 100 of the embodiment of the present invention, the door rotation axis 13 of the household appliance 100 is located on one side of the take-in and put-out port 11 along the left-right direction. By making the door rotation axis 13 extend backward in an inclined direction from bottom to top, the self-gravity of the door 12 can slow down the automatic opening process of the door 12, thereby preventing the door 12 from being ejected too wide when opening, causing the door 12 to collide with people or other devices near the household appliance 100; and, during the opening process of the door 12, the minimum distance between the door 12 and the ground can gradually increase, thereby reducing the collision of the door 12 with other devices in front of the household appliance 100 or the edge of the body 10 when the door 12 sags due to its own gravity.

[0043] According to some embodiments of the present invention, referring to Figure 4 The plane perpendicular to the front-to-back direction is the first reference plane 40. The front-to-back direction is perpendicular to the vertical direction. The angle α between the door rotation axis 13 and the first reference plane 40 is 0.5° to 30°. For example, the value of α can be 0.5°, 1°, 2°, 5°, 8°, 10°, 15°, 20°, 25°, 30°, etc. During the process of opening the door body 12, the self-weight of the door body 12 has a component force for the door body 12 to rotate in the direction of closing the take-in and put-out port 11. By making the angle α between the door body rotation axis 13 and the first reference plane 40 not less than 0.5°, the self-weight of the door body 12 can have a larger component force for the door body 12 to rotate in the direction of closing the take-in and put-out port 11, which can effectively slow down the automatic opening process of the door body 12, and better avoid the door body 12 being ejected too large when it is ejected, thereby avoiding collision with other devices during the automatic opening process of the door body 12; by making the angle α between the door body rotation axis 13 and the first reference plane 40 not greater than 30°, it can avoid the inclination angle of the rotating shaft 33 being too large to be difficult to assemble, and it can also avoid the rotating shaft 33 tilting backward too much to occupy the space of the rear working chamber.

[0044] Optionally, the value range of α is 1° to 5°. For example, α can be 1°, 2°, 3°, 4°, or 5°.

[0045] According to some embodiments of the present invention, referring to Figure 3 The door body rotation axis 13 is located on the left side of the access opening 11, and the door body rotation axis 13 extends obliquely to the left from bottom to top. When the door body 12 is opened at a large angle, the elastic force of the elastic member for driving the door body 12 to open is weakened. When the door body rotation axis 13 is located on the left side of the access opening 11, by making the door body rotation axis 13 extend obliquely to the left from bottom to top, the door body 12's own weight has a component force for rotating the door body 12 in the direction of opening the access opening 11, which can ensure that the door body 12 is fully opened, for example, it can ensure that the door body 12 is rotated to the second position 15, and the door body 12's own weight has a component force for rotating the door body 12 in the direction of opening the access opening 11, for example, it can make the door body 12 better maintained in the second position 15, so that the door body 12 can better maintain the position of opening the access opening 11, so as to facilitate users to take out or put in items.

[0046] The opening angle of the door body 12 refers to the angle at which the door body 12 rotates when the door body 12 rotates from the position where the access opening 11 is closed to the current position.

[0047] For example, refer to Figure 5The rotation axis 33 of the door body 12 is located on the left side of the access opening 11. The door body rotation axis 13 extends obliquely to the left from bottom to top, and extends obliquely to the rear from bottom to top. The projection of the door body rotation axis 13 on the horizontal plane is a first projection 41, the plane perpendicular to the front-to-back direction is a first reference plane 40, and the angle between the first projection 41 and the first reference plane 40 is a first angle θ. When the opening angle of the door body 12 is less than the first angle θ, the door body 12's own weight has a component force for rotating the door body 12 in the direction of closing the access opening 11, so as to prevent the door body 12 from being excessively opened by the elastic member and colliding with people or other devices; when the opening angle of the door body 12 is greater than the first angle θ, the door body 12's own weight has a component force for rotating the door body 12 in the direction of opening the access opening 11, so that the door body 12 is continuously in the state of opening the access opening 11, making it more convenient for users to take out or put in items. When the opening angle of the door body 12 is equal to the first angle θ, the door body 12 is in the third position 16, and the opening angle of the door body 12 and the first angle θ are vertical angles. The self-gravity of the door body 12 has neither a component force for rotating the door body 12 toward the direction of opening the access port 11 nor a component force for rotating the door body 12 toward the direction of closing the access port 11.

[0048] The opening angle of the door body 12 is the angle between the position of the door body 12 and the first position 14 .

[0049] According to some embodiments of the present invention, the door body rotation axis 13 is located on the right side of the access opening 11, and the door body rotation axis 13 extends obliquely to the right from bottom to top. The projection of the door body rotation axis 13 on the horizontal plane is a first projection 41, the plane perpendicular to the front-to-back direction is a first reference plane 40, and the angle between the first projection 41 and the first reference plane 40 is a first angle θ. When the opening angle of the door body 12 is less than the first angle θ, the self-weight of the door body 12 has a component force for rotating the door body 12 in the direction of closing the access opening 11, so as to prevent the door body 12 from being excessively opened by the elastic member and colliding with people or other devices; when the opening angle of the door body 12 is greater than the first angle θ, the self-weight of the door body 12 has a component force for rotating the door body 12 in the direction of opening the access opening 11, so that the door body 12 is continuously in the state of opening the access opening 11, making it more convenient for users to take out or put in items. When the opening angle of the door body 12 is equal to the first angle θ, the door body 12 is in the third position 16, and the opening angle of the door body 12 and the first angle θ are vertical angles. The self-gravity of the door body 12 has neither a component force for rotating the door body 12 toward the direction of opening the access port 11 nor a component force for rotating the door body 12 toward the direction of closing the access port 11.

[0050] According to some embodiments of the present invention, referring to Figure 3The plane perpendicular to the left-right direction is the second reference plane. The left-right direction is perpendicular to the vertical direction. The angle between the door rotation axis 13 and the second reference plane is β, and the value range of β is 0.5° to 30°. For example, the value of β can be 0.5°, 1°, 2°, 5°, 8°, 10°, 15°, 20°, 25°, 30°, etc. When the opening angle of the door body 12 is large, the self-weight of the door body 12 has a component force on the door body 12 to rotate toward the direction of opening the take-in and put-out port 11. By making the angle β between the door body rotation axis 13 and the second reference plane not less than 0.5°, the effect of the rotation axis can be made large enough to ensure that when the opening angle of the door body 12 is large, the self-weight of the door body 12 has a component force on the door body 12 to rotate toward the direction of opening the take-in and put-out port 11, ensuring that the door body 12 is fully opened, so that the door body 12 is better maintained in the second position 15, to facilitate users to take out or put in items; by making the angle β between the door body rotation axis 13 and the second reference plane not greater than 30°, it can avoid the inclination angle of the rotating shaft 33 being too large to be difficult to assemble, and it can also avoid the rotating shaft 33 being too large to the left or right to occupy the space of the left or right working cavity.

[0051] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The plane perpendicular to the front-to-back direction is the first reference plane 40, the front-to-back direction is perpendicular to the vertical direction, and the angle between the door body rotation axis 13 and the first reference plane 40 is α, and α and β satisfy: α≥β. By making the angle α between the door body rotation axis 13 and the first reference plane 40 ≥ the angle β between the door body rotation axis 13 and the second reference plane, the door body 12 can be opened at least in the first half of the stroke, and the door body 12 can be rotated by its own weight in the direction of closing the access port 11. Only after the door body 12 rotates to the second half of the stroke, the door body 12 can be rotated by its own weight in the direction of opening the access port 11. In this way, during the opening process of the door body 12, the automatic opening process of the door body 12 can be effectively slowed down, and the door body 12 can be prevented from being ejected too wide when it is opened, causing the door body 12 to collide with people or other devices near the household appliance 100. It can also ensure that the door body 12 is fully opened, and the door body 12 can be better maintained in the position of opening the access port 11 (for example, the second position 15), so as to facilitate users to take out or put in items.

[0052] According to some embodiments of the present invention, referring to Figure 3 and Figure 4The difference between α and β ranges from 0.5° to 15°. For example, the difference between α and β can be 0.5°, 1°, 2°, 5°, 10°, 15°, etc. By making the difference between α and β not less than 0.5°, it can be ensured that the effect of the door body rotation axis 13 extending in an oblique direction toward the rear from bottom to top can be stronger and more obvious, so that in a larger range between opening and closing the access port 11, the door body 12's own gravity has a larger component of force for the door body 12 to rotate in the direction of closing the access port 11, which can effectively slow down the automatic opening process of the door body 12, and better avoid the door body 12 being ejected too wide when it is opened, causing the door body 12 to collide with people or other devices near the household appliance 100; by making the difference between α and β not more than 15°, the effect of the door body rotation axis 13 extending in an oblique direction toward the left or right from bottom to top can be more sufficient, so that when the door body 12 is opened at a larger angle, the door body 12's own gravity has a component of force for the door body 12 to rotate to open the access port 11, ensuring that the door body 12 is opened in place, for example, the door body 12 can be better maintained in the second position 15, to facilitate users to take out or put in items.

[0053] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the ratio of α to β ranges from 1 to 2. For example, the ratio of α to β can be 1, 1.2, 1.4, 1.6, 1.8, 2, etc. By making the ratio of α to β not less than 1, it can be ensured that the effect of the door body rotation axis 13 extending in an inclined direction from bottom to top can be stronger and more obvious, so that the door body 12 has a larger component force for rotating the door body 12 in the direction of closing the access port 11 due to its own gravity within a larger range between opening and closing the access port 11, which can effectively slow down the automatic opening process of the door body 12, and better avoid the door body 12 being ejected when opening too large, resulting in the door body 12 and people near the household appliance 100. or collision with other devices; by making the ratio of α to β not greater than 2, the door body rotation axis 13 can be made to extend in an inclined direction to the left or right from bottom to top more effectively, so that when the door body 12 is opened at a large angle, the door body 12's own gravity has a component force on the door body 12 to open the take-and-put port 11 and rotate it, ensuring that the door body 12 is fully opened. For example, the door body 12 can be better maintained in the second position 15, and the door body 12 is affected by its own gravity to rotate in the direction of opening the door, so as to facilitate users to take out or put in items.

[0054] According to some embodiments of the present invention, referring to Figure 1 and Figure 2The door body 12 can rotate between a first position 14 and a second position 15. In the first position 14, the door body 12 closes the access opening 11, and in the second position 15, the door body 12 opens the access opening 11; for example, when the door body 12 is in the second position 15, the opening angle of the door body 12 is the largest.

[0055] The door body 12 also has a third position 16, and the third position 16 is located between the first position 14 and the second position 15. When the door body 12 is located between the first position 14 and the third position 16, the self-weight of the door body 12 has a component force for the door body 12 to move toward the first position 14. After the door body 12 rotates to the second half of the stroke, the self-weight of the door body 12 has a component force for the door body 12 to rotate toward the direction of opening the access port 11. In this way, during the process of opening the door body 12, the door body 12 can be better slowed down. The automatic pop-up process of 12 prevents the door body 12 from being popped open too wide when it pops open, causing the door body 12 to collide with people or other devices near the household appliance 100. When the door body 12 is between the third position 16 and the second position 15, the self-gravity of the door body 12 has a component force for the door body 12 to move toward the second position 15, which can ensure that the door body 12 is fully opened and can make the door body 12 better maintained in the position of opening the access port 11 (for example, the second position 15), so that the user can take out or put in items conveniently.

[0056] The rotation angle between the first position 14 and the third position 16 is a first rotation angle a, and the rotation angle between the second position 15 and the third position 16 is a second rotation angle b. The first rotation angle a is not less than the second rotation angle b. If the first rotation angle a is too small, the door will easily be positioned between the second position 15 and the third position 16 after it is opened. At this time, the weight of the door 12 exerts a force component on the door 12 to open the access opening 11, increasing the door opening and causing the door 12 to collide with people or other devices near the household appliance 100. By ensuring that the first rotation angle a is not less than the second rotation angle b, the first rotation angle a is sufficiently large so that the door is positioned between the first position 14 and the third position 16 after it is opened. In this range, the weight of the door 12 exerts a greater force component on the door 12 to close the access opening 11, effectively slowing the automatic opening process of the door 12 and preventing the door 12 from being opened too wide during opening, thereby preventing the door 12 from colliding with people or other devices near the household appliance 100.

[0057] For example, door rotation axis 13 is located to the left of access opening 11. Door rotation axis 13 extends obliquely to the left from bottom to top, and also extends obliquely to the rear from bottom to top. The projection of door rotation axis 13 on a horizontal plane is a first projection 41. A plane perpendicular to the left-right direction is a second reference plane. The angle between first projection 41 and the second reference plane is a first angle. According to mathematical relationships, the first angle is equal to the first rotation angle a.

[0058] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The household appliance 100 includes a door hinge 30, which includes a first hinge plate 31, a second hinge plate 32, and a rotating shaft 33. The first hinge plate 31 is fixed to the housing 10 and has a first rotation hole 34. The second hinge plate 32 is fixed to the door 12 and has a second rotation hole 35. The rotating shaft 33 passes through the first rotation hole 34 and the second rotation hole 35. The central axis of the rotating shaft 33, the central axis of the first rotation hole 34, and the central axis of the first rotation hole 34 coincide and form the door body rotation axis 13. By fixing the first hinge plate 31 to the housing 10, fixing the second hinge plate 32 to the door 12, and passing the rotating shaft 33 through the first rotation hole 34 and the second rotation hole 35, the door 12 can rotate relative to the housing 10 about the rotating shaft 33 to open or close the access opening 11.

[0059] For example, the household appliance 100 includes an elastic member,

[0060] One end of the elastic member is connected to the body 10 and the other end of the elastic member is connected to the door body 12. The elastic member is used to drive the door body 12 to rotate to open the access opening 11. In this way, the door body 12 can be automatically opened by the elastic member driving the door body 12, and the door body 12 can be automatically opened under the elastic force of the elastic member.

[0061] For example, the elastic member is a torsion spring, which is sleeved on the rotating shaft 33 of the door body 12. One end of the elastic member is connected to the body 10, and the other end of the elastic member is connected to the door body 12. When the door body 12 is in a state of closing the access port 11, the elastic member is compressed; when the user needs to open the door body 12, the elastic member bounces the door body 12 open to open the access port 11.

[0062] According to some embodiments of the present invention, referring to Figure 2The door body 12 is rotatable between a first position 14 and a second position 15. In the first position 14, the door body 12 closes the access opening 11, and in the second position 15, the door body 12 opens the access opening 11. During the movement of the door body 12 from the first position 14 to the second position 15, the height of the highest position of the door body 12 gradually increases. By gradually increasing the height of the highest position of the door body 12 during the movement of the door body 12 from the first position 14 to the second position 15, the collision between the door body 12 and the lower parts near the household appliance 100 can be reduced, and the collision between the door body 12 and the edge of the body 10 when closing the door can also be reduced. Moreover, since the human body is usually taller than the household appliance 100, it can also conform to the human-machine interface and enhance the user experience.

[0063] According to some embodiments of the present invention, referring to Figure 2 In the first position 14, the highest position of the door body 12 is the first highest position 36. In the second position 15, the highest position of the door body 12 is the second highest position 37. The height difference between the second highest position 37 and the first highest position 36 is h. The value range of h is 30 mm to 110 mm. For example, the value of h can be 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, etc. By ensuring that the height difference between the second highest position 37 and the first highest position 36 is not less than 30 mm, the effect of the second highest position 37 in raising the height of the door body 12 can be made more obvious, thereby reducing to a greater extent the collision between the door body 12 and nearby components of the household appliance 100 or the collision between the door body 12 and the edge of the body 10; by ensuring that the height difference between the second highest position 37 and the first highest position 36 is not greater than 110 mm, it is possible to avoid that the height difference between the second highest position 37 and the first highest position 36 is too large, and correspondingly, the angle between the rotation axis and the first reference plane 40 is too large, making it difficult to assemble the door body 12.

[0064] The household appliance 100 according to some embodiments of the present invention will be described below with reference to the drawings.

[0065] In this embodiment, the household appliance 100 is a washing machine, and the household appliance 100 includes a body 10, a door 12, and an elastic member.

[0066] The body 10 has a working chamber and a loading and unloading port 11 located at the front side of the working chamber.

[0067] The door body 12 is rotatably connected to the body 10 to open or close the access opening 11. The rotation axis of the door body 12 is the door body rotation axis 13. The door body rotation axis 13 is located on one side of the access opening 11 along the left-right direction. The door body rotation axis 13 extends obliquely toward the rear from bottom to top. The plane perpendicular to the front-to-back direction is the first reference plane 40. The front-to-back direction is perpendicular to the vertical direction. The angle between the door body rotation axis 13 and the first reference plane 40 is α, and the value range of α is 0.5° to 30°. The door body rotation axis 13 is located on the left side of the access opening 11. The door body rotation axis 13 extends obliquely toward the left from bottom to top. The plane perpendicular to the left and right direction is the second reference plane, the left and right direction is perpendicular to the vertical direction, the angle between the door body rotation axis 13 and the second reference plane is β, the value range of β is 0.5°~30°, α and β satisfy: α≥β, the difference range of α and β is 0.5°~15°, and the ratio range of α and β is 1~2.

[0068] The door body 12 is rotatable between a first position 14 and a second position 15. In the first position 14, the door body 12 closes the access opening 11, and in the second position 15, the door body 12 opens the access opening 11. The door body 12 also has a third position 16, which is located between the first position 14 and the second position 15. When the door body 12 is between the first position 14 and the third position 16, the door body 12's own weight has a component force for the door body 12 to move toward the first position 14. When the door body 12 is between the third position 16 and the second position 15, the door body 12's own weight has a component force for the door body 12 to move toward the second position 15. The rotation angle between the first position 14 and the third position 16 is a first rotation angle, and the rotation angle between the second position 15 and the third position 16 is a second rotation angle. The first rotation angle is not less than the second rotation angle. As the door body 12 moves from the first position 14 to the second position 15, the height of the highest position of the door body 12 gradually increases. In the first position 14 , the highest position of the door body 12 is a first highest position 36 . In the second position 15 , the highest position of the door body 12 is a second highest position 37 . The height difference between the second highest position 37 and the first highest position 36 is 30 mm to 110 mm.

[0069] The household appliance 100 includes a door hinge 30, which includes a first hinge plate 31, a second hinge plate 32 and a rotating shaft 33. The first hinge plate 31 is fixed to the body 10 and has a first rotating hole 34. The second hinge plate 32 is fixed to the door body 12 and has a second rotating hole 35. The rotating shaft 33 is passed through the first rotating hole 34 and the second rotating hole 35. The central axis of the rotating shaft 33, the central axis of the first rotating hole 34 and the central axis of the first rotating hole 34 coincide and constitute the door body rotation axis 13.

[0070] One end of the elastic member is connected to the housing 10 and the other end is connected to the door 12. The elastic member is used to drive the door 12 to rotate to open the access opening 11. The elastic member includes a spring, a first elastic end, and a second elastic end. The spring is fixed to the rotating shaft 33, and the axis of the spring coincides with the central axis of the rotating shaft 33. The first elastic end is connected to the housing 10, and the second elastic end is connected to the door 12. When the door 12 is in the state of closing the access opening 11, the elastic member is compressed; when the user needs to open the door 12, the elastic member recovers and pops the door 12 open to open the access opening 11.
