Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a door assembly and a washing machine containing the same. Background Technology

[0002] During washing, especially spin-drying, traditional washing machines have significant relative movement between the inner and outer drums and the cabinet. However, to ensure the water seal inside the drum, a soft rubber door seal is used to connect the drum and the cabinet. By using an inner and outer door design, the inner door moves with the drum, while the outer door connects to the cabinet, blocking the inner door and preventing the door movement from being visible, thus improving safety.

[0003] The existing technology has the following disadvantages:

[0004] 1. In actual use, rubber door seals often retain a lot of stains, which are not easy to clean;

[0005] Second, in existing products, the door is directly installed on the cylinder. During operation, the door and the cylinder move together relative to the outer casing, eliminating the door seal structure and improving the above-mentioned problems. However, this method also has certain safety hazards because the movement of the door is visible.

[0006] Third, the way the outer door is set up is inconvenient to operate; to get clothes, you have to open the outer door first and then the inner door.

[0007] Fourth, the inner and outer doors of the washing machine are not convenient to open and close in one go. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defect in the prior art that the inner and outer doors of washing machines are inconvenient to open and close in one go, and to provide a door assembly and a washing machine containing the assembly.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] A door assembly includes an inner door, an outer door, and a linkage device, the linkage device comprising:

[0011] The first linkage component is located on the outer door;

[0012] The second linkage component is installed on the surface of the inner door facing the outer door;

[0013] The second linkage includes a first abutting part and a second abutting part. The first linkage can rotate under external force, so that the first linkage can abut against the first abutting part and can abut against the second abutting part.

[0014] When the outer door is subjected to external force, it can cause the inner door to switch between a closed state and an open state.

[0015] During the transition from the closed state to the open state, the outer door is configured to open the inner door when it moves to the point where the first linkage abuts against the first abutting mating part;

[0016] During the transition from the open state to the closed state, the outer door is configured to close the inner door when it moves to the point where the first linkage abuts against the second abutting mating part.

[0017] In this solution, the aforementioned linkage device facilitates the linkage between the first linkage member on the outer door and the second linkage member on the inner door when the outer door is subjected to external force. This allows the outer door to drive the inner door to open, enabling the inner and outer doors of the washing machine to open and close in one operation. Furthermore, the first and second linkage members engage in abutment-type linkage, resulting in a simpler structure and linkage method for the linkage device. When the linkage device is used in a washing machine, the inner and outer doors are linked. As the inner door moves with the drum, the outer door connects to the cabinet, effectively blocking the inner door and preventing the door movement from being visible, thus improving safety.

[0018] Preferably, the first linkage includes a handle and an abutment connected to each other, the first linkage passing through the outer door so that the handle is located on the side of the outer door away from the inner door, and the abutment is located on the side of the outer door closer to the inner door;

[0019] When the handle is subjected to external force, it can drive the abutment to move, so that the abutment can abut against the first abutment mating part and the second abutment mating part.

[0020] In this design, the first linkage passes through the outer door so that the handle is located on the side of the outer door away from the inner door, and the abutment is located on the side of the outer door closer to the inner door. The handle is positioned to facilitate the application of external force to the first linkage, and the abutment is positioned to prevent it from being exposed to the outside of the washing machine and contaminated by air dust, which would affect its lifespan. In addition, the fact that the first linkage passes through the outer door to make the handle also makes the connection between the first linkage and the outer door more secure, and the first linkage is less likely to detach from the outer door.

[0021] Preferably, the abutting member includes a first abutting portion and a second abutting portion.

[0022] The handle is configured such that when rotated by an external force, it causes the first abutting part to rotate to a state where it overlaps with the first abutting mating part. The handle is also configured such that when rotated by an external force, it causes the first abutting part to move from a state where it overlaps with the first abutting mating part to a state where it abuts with the first abutting mating part, thereby causing the inner door to open.

[0023] The handle is configured such that when rotated by an external force, it causes the second abutment portion to rotate until it partially overlaps with the second abutment mating portion. The handle is also configured such that, when subjected to an external force, it causes the second abutment portion to move from an overlapping state with the second abutment mating portion to a abutting state with the second abutment mating portion, thereby closing the inner door; or...

[0024] The handle is configured to rotate the first abutting part to directly abut against the first abutting mating part when subjected to external force. The handle is also configured to move the abutting member away from the inner door when subjected to external force, so as to open the inner door.

[0025] The handle is configured to rotate the second abutment part to directly abut against the second abutment mating part when subjected to external force. The handle is also configured to move the abutment member toward the inner door when subjected to external force, thereby closing the inner door.

[0026] In this solution, the first abutting part and the second abutting part can be used interchangeably to avoid damage to the abutting part due to prolonged use of either part. In addition, the overlapping state setting prevents the abutting part from rotating directly to the abutting state, thus preventing the abutting part from accidentally opening or closing an inner door that should not be closed when it rotates.

[0027] Preferably, the first abutting part includes a first plate and a second plate connected at an angle, the first plate is installed on the inner door and facing the outer door, the second plate and the inner door form a first receiving space, and the second abutting part and the outer door form a second receiving space;

[0028] During the process of switching from the closed state to the open state, the abutment is located in the first receiving space and abuts against the second plate;

[0029] During the process of switching from the open state to the closed state, the abutting member is located in the second receiving space and abuts against the second abutting mating part.

[0030] In this solution, the above-mentioned arrangement places the second linkage between the outer door and the inner door, preventing the second linkage from being exposed to the outside of the washing machine and contaminated by air dust, which would affect its lifespan. In addition, the arrangement of the first and second accommodating spaces also facilitates the movement of the first and second abutting parts. The first plate is installed on the inner door and faces the outer door. The above-mentioned arrangement makes the second plate closer to the outer door, which facilitates the abutting parts abutting.

[0031] Preferably, the abutment further includes a connecting rod, the first end of which is connected to the handle, and the second end of which is integrally formed with the first abutment portion and the second abutment portion. The first abutment portion and the second abutment portion are located between the first abutment mating portion or the second abutment mating portion. The handle is configured to drive the first abutment portion toward the first receiving space when rotated by an external force, and the handle is also configured to drive the second abutment portion toward the second receiving space when rotated by an external force.

[0032] In this design, the second end of the connecting rod is integrally formed with the first and second abutting parts, making the first linkage easy to process. Moreover, the first linkage produced in this way saves space and is not easily damaged. The first and second abutting parts are located between the first and second abutting mating parts. This arrangement saves space and also brings the abutting part closer to the first or second abutting mating part, making it easier for the abutting part to move toward the first or second receiving space.

[0033] Preferably, the second abutting part is an abutting block, and the outer surface of the first abutting part facing the outer door, the inner surface of the first abutting part facing the inner door, the inner surface of the second plate facing the inner door, and the outer surface of the abutting block facing the outer door are all arc-shaped surfaces;

[0034] The contact point between the first abutting part and the first linkage member is the intersection of the motion trajectory line of the outer surface of the first abutting part and the arc surface of the inner surface of the second plate.

[0035] The contact point between the second contacting part and the first linkage part is the intersection of the motion trajectory line of the outer surface of the second contacting part and the arc surface of the outer surface of the contact block.

[0036] In this solution, the above-mentioned arrangement allows the first linkage to slide smoothly into the abutment block or the second plate without damaging the abutment block or the second plate, and the operation is smooth without jamming, vibration, or impact noise.

[0037] Preferably, the door assembly further includes a first hinge that hinges the first linkage member to the outer door.

[0038] In this design, the first hinge allows the first linkage to be more securely installed on the outer door.

[0039] Preferably, the first linkage further includes a reset device, which is disposed inside the handle.

[0040] When the outer door moves to the inner door in the closed state, the reset device acts on the handle to provide a restoring force to the handle in the opening direction of the outer door, so that the second abutting part and the second abutting mating part are in a non-abutting state.

[0041] In this design, the reset device enables the outer door to reset when the inner door is closed, thus separating the outer and inner doors. Consequently, vibrations from the inner door are not directly transmitted to the outer door, improving vibration isolation. Furthermore, the reset device is located inside the handle, preventing it from being exposed to dust and thus extending its lifespan.

[0042] Preferably, the door assembly further includes a second hinge, which is disposed at the edge of the outer door and connected between the inner door and the outer door, and a linkage device is disposed on the side of the door assembly opposite to the second hinge.

[0043] In this design, the second hinge allows the inner and outer doors to be stably installed together, while also enabling the first and second linkage components to operate stably. The second hinge design also saves space. Furthermore, the linkage device is located on the side of the door assembly opposite to the hinge, which does not interfere with the cooperation of the first and second linkage components. This facilitates the opening of the inner and outer doors and allows for a large opening range, making it convenient to put in and take out clothes.

[0044] This utility model also provides a washing machine, which includes the above-mentioned door assembly.

[0045] The positive and progressive effects of this utility model are as follows: the above-mentioned linkage device facilitates the linkage between the first linkage member on the outer door and the second linkage member on the inner door when the outer door is subjected to external force, thereby facilitating the opening of the inner door by the outer door, so that the inner and outer doors of the washing machine can be opened and closed in one step. Furthermore, the first and second linkage members are linked by abutting contact, which makes the structure of the linkage device simpler and the linkage method simpler. When the linkage device is used in a washing machine, the inner and outer door linkage is adopted. The inner door moves with the drum, and the outer door is connected to the cabinet, which can block the inner door and prevent the door movement from being visible, thus improving safety.

[0071] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0072] like Figure 1-4As shown, this embodiment provides a door assembly 300, which includes an inner door 3, an outer door 2, and a linkage device 1. The linkage device 1 includes: a first linkage member 11, which is disposed on the outer door 2; and a second linkage member 12, which is disposed on the surface of the inner door 3 facing the outer door 2. The second linkage member 12 includes a first abutting engagement portion 121 and a second abutting engagement portion 122. The first linkage member 11 can rotate under external force, and can abut against the first abutting engagement portion 121 and the second abutting engagement portion 122. When the outer door 2 is subjected to external force, it can drive the inner door 3 to switch between a closed state and an open state. During the process of switching from the closed state to the open state, the outer door 2 is configured to drive the inner door 3 to open when it moves to the point where the first linkage member 11 abuts against the first abutting engagement portion 121. During the process of switching from the open state to the closed state, the outer door 2 is configured to drive the inner door 3 to close when it moves to the point where the first linkage member 11 abuts against the second abutting engagement portion 122.

[0073] In this embodiment, the aforementioned linkage device 1 is designed so that when the outer door 2 is subjected to external force, the first linkage member 11 on the outer door 2 and the second linkage member 12 on the inner door 3 are linked together, thereby facilitating the outer door 2 to drive the inner door 3 to open. This allows the inner and outer doors 2 of the washing machine 100 to open and close in one step. Furthermore, the first linkage member 11 and the second linkage member 12 are linked by abutting contact, making the structure of the linkage device 1 simpler and the linkage method simpler. When the linkage device 1 is used in the washing machine 100, the inner door 3 and outer door 2 are linked. The inner door 3 moves with the drum 400, and the outer door 2 is connected to the cabinet 200, which can block the inner door 3, preventing the door movement from being visible and improving safety.

[0074] It should be noted that the first linkage 11 and the second linkage 12 are located between the inner door 3 and the outer door 2, which is more aesthetically pleasing. Moreover, the first linkage 11 and the second linkage 12 are not easily affected by external air, dust and other environmental factors, and have a longer service life. In addition, the inner door 3 is installed on the cylinder 400. Furthermore, it should be noted that the first abutting part 121 is located near the middle of the inner door 3, and the second abutting part 122 is located near the edge of the inner door 3. The first linkage 11 rotates along the second abutting part 122 toward the first abutting part 121.

[0075] like Figure 1-4 As shown, the first linkage 11 includes a handle 111 and an abutment 112 connected to each other. The first linkage 11 passes through the outer door 2 so that the handle 111 is located on the side of the outer door 2 away from the inner door 3, and the abutment 112 is located on the side of the outer door 2 closer to the inner door 3. When the handle 111 is subjected to external force, it can drive the abutment 112 to move so that the abutment 112 can abut against the first abutment engagement part 121 and the second abutment engagement part 122.

[0076] In this embodiment, the first linkage 11 passes through the outer door 2 so that the handle 111 is located on the side of the outer door 2 away from the inner door 3, and the abutment 112 is located on the side of the outer door 2 closer to the inner door 3. The handle 111 is positioned to facilitate the application of external force to the first linkage 11. The abutment 112 is positioned in a way that prevents it from being exposed to the outside of the washing machine 100 and being contaminated by air dust, which would affect its lifespan. In addition, the first linkage 11 passing through the outer door 2 so that the handle 111 is positioned makes the connection between the first linkage 11 and the outer door 2 more stable, and the first linkage 11 is less likely to detach from the outer door 2.

[0077] It should be noted that the handle 111 mentioned above is for the operator to operate.

[0078] like Figure 4 As shown, the abutting member 112 includes a first abutting portion 1121 and a second abutting portion 1122.

[0079] The handle 111 is configured to rotate the first abutting part 1121 to a partially overlapping state with the first abutting mating part 121 when subjected to external force. The handle 111 is also configured to move the first abutting part 1121 from an overlapping state with the first abutting mating part 121 to an abutting state with the first abutting mating part 121 when subjected to external force, thereby driving the inner door 3 to open.

[0080] The handle 111 is configured such that when rotated by an external force, it causes the second abutment portion 1122 to rotate until it partially overlaps with the second abutment mating portion 122. The handle 111 is also configured such that when subjected to an external force, it causes the second abutment portion 1122 to move from an overlapping state to a abutting state with the second abutment mating portion 122, thereby closing the inner door 3; or...

[0081] The handle 111 is configured to rotate the first abutting part 1121 to abutting directly with the first abutting mating part 121 when it is rotated by an external force. The handle 111 is also configured to move the abutting part 112 away from the inner door 3 when it is rotated by an external force, so as to open the inner door 3.

[0082] The handle 111 is configured to rotate the second abutment part 1122 to abut against the second abutment mating part 122 when subjected to external force. The handle 111 is also configured to move the abutment part 112 toward the inner door 3 when subjected to external force, so as to close the inner door 3.

[0083] In this embodiment, the first abutting part 1121 and the second abutting part 1122 can be used interchangeably to avoid damage to the abutting member 112 due to prolonged use of the first abutting part 1121 or the second abutting part 1122. In addition, the overlapping state setting can prevent the abutting member 112 from rotating directly to the abutting state, thus preventing the abutting member 112 from accidentally opening or closing the inner door 3 that should not be opened or closed when it rotates accidentally.

[0084] It should be noted that the rotation of the first linkage 11 is not necessarily caused by an external force; it can also be controlled by an intelligent device such as a motor.

[0085] like Figure 1-4 As shown, the first abutting part 121 includes a first plate 1211 and a second plate 1212 connected at an angle. The first plate 1211 is installed on the inner door 3 and faces the outer door 2. The second plate 1212 and the inner door 3 form a first receiving space. The second abutting part 122 and the outer door 2 form a second receiving space. During the process of switching from the closed state to the open state, the abutting member 112 is located in the first receiving space and abuts against the second plate 1212. During the process of switching from the open state to the closed state, the abutting member 112 is located in the second receiving space and abuts against the second abutting part 122.

[0086] In this embodiment, the above-mentioned arrangement places the second linkage 12 between the outer door 2 and the inner door 3, preventing the second linkage 12 from being exposed to the outside of the washing machine 100 and contaminated by air dust, which would affect its lifespan. In addition, the arrangement of the first and second accommodating spaces also facilitates the movement of the first abutting part 1121 and the second abutting part 1122. The first plate 1211 is installed on the inner door 3 and is positioned towards the outer door 2. The above-mentioned arrangement makes the second plate 1212 closer to the outer door 2, which facilitates the abutting part 112 abutting.

[0087] It should be noted that one end of the first plate 1211 is installed on the inner door 3, and the other end extends toward the outer door 2. The extension direction of the second plate 1212 is parallel to the outer surface of the inner door 3.

[0088] like Figure 4 As shown, the abutment member 112 also includes a connecting rod 1123. The first end of the connecting rod 1123 is connected to the handle 111, and the second end of the connecting rod 1123 is integrally formed with the first abutment portion 1121 and the second abutment portion 1122. The first abutment portion 1121 and the second abutment portion 1122 are located between the first abutment mating portion 121 or the second abutment mating portion 122. The handle 111 is configured to drive the first abutment portion 1121 toward the first receiving space when rotated by an external force. The handle 111 is also configured to drive the second abutment portion 1122 toward the second receiving space when rotated by an external force.

[0089] In this embodiment, the second end of the connecting rod 1123 is integrally formed with the first abutting part 1121 and the second abutting part 1122, making the first linkage 11 easy to process. Moreover, the first linkage 11 processed in this way saves space and is not easily damaged. The first abutting part 1121 and the second abutting part 1122 are located between the first abutting mating part 121 or the second abutting mating part 122. This arrangement saves space and at the same time shortens the distance between the abutting part 112 and the first abutting mating part 121 or the second abutting mating part 122, making it convenient for the abutting part 112 to move toward the first receiving space or the second receiving space.

[0090] It should be noted that the reset device 4 is mounted on the connecting rod 1123.

[0091] like Figure 3-4 As shown, the second abutting part 122 is an abutting block. The outer surface of the first abutting part 1121 facing the outer door 2, the inner surface of the first abutting part 1121 facing the inner door 3, the inner surface of the second plate 1212 facing the inner door 3, and the outer surface of the abutting block facing the outer door 2 are all arc-shaped surfaces. The abutting point of the first abutting part 121 and the first linkage member 11 is the intersection of the movement trajectory line of the outer surface of the first abutting part 1121 and the arc surface of the inner surface of the second plate 1212. The abutting point of the second abutting part 122 and the first linkage member 11 is the intersection of the movement trajectory line of the outer surface of the second abutting part 1122 and the arc surface of the outer surface of the abutting block.

[0092] In this embodiment, the above-mentioned arrangement allows the first linkage 11 to slide smoothly into the abutment block or the second plate 1212 without damaging the abutment block or the second plate 1212, and the operation is smooth and without jamming, vibration or impact noise.

[0093] The door assembly 300 also includes a first hinge that hinges the first linkage 11 to the outer door 2.

[0094] In this embodiment, the first hinge makes the first linkage 11 more securely mounted on the outer door 2.

[0095] It should be noted that the first hinge can also be replaced by other components that can install the first linkage 11 to the outer door 2, such as a snap-fit ​​connector or a bolt connector, and the first hinge is not shown in the attached drawings.

[0096] like Figure 4 As shown, the first linkage 11 also includes a reset device 4, which is disposed inside the handle 111. When the outer door 2 moves to the inner door 3 in the closed state, the reset device 4 acts on the handle 111 to provide a restoring force to the handle 111 in the opening direction of the outer door 2, so that the second abutting part 1122 and the second abutting mating part 122 are in a non-abutting state.

[0097] In this embodiment, the reset device 4 enables the outer door 2 to reset when the inner door 3 is closed, so that the outer door 2 is separated from the inner door 3. As a result, the vibration of the inner door 3 is not directly transmitted to the outer door 2, thus improving the vibration isolation effect. In addition, the reset device 4 is located inside the handle 111. This arrangement avoids the reset device 4 being exposed to the outside of the washing machine 100 and being contaminated by air dust, which would affect its lifespan.

[0098] It should be noted that the reset device 4 is a component with a reset function, such as a spring or a rubber component; in addition, when the washing machine 100 is running, there are gaps between the abutting part 112 and the first abutting mating part 121 and the second abutting mating part 122, which allows the inner door 3 and the outer door 2 to move relative to each other within a certain range without vibration transmission, thus improving the overall vibration and noise performance of the machine.

[0099] like Figure 1-4 As shown, the door assembly 300 also includes a second hinge 5, which is disposed at the edge of the outer door 2 and connected between the inner door 3 and the outer door 2. The linkage device 1 is disposed on the side of the door assembly 300 opposite to the second hinge 5.

[0100] In this embodiment, the second hinge 5 allows the inner door 3 and outer door 2 to be stably installed together, while also enabling the first linkage 11 and the second linkage 12 to work stably. Furthermore, the arrangement of the second hinge 5 saves space. Additionally, the linkage device 1 is located on the side of the door assembly 300 opposite to the hinge 5, which does not interfere with the cooperation of the first linkage 11 and the second linkage 12, facilitating the opening of the inner door 3 and outer door 2, and allowing for a large opening range for easy access to clothing. Figure 1 As shown, the present invention also provides a washing machine 100, which includes the aforementioned door assembly 300.

[0101] The process of switching the door assembly 300 from the closed state to the open state is as follows: The outer door 2 is configured to drive the inner door 3 to open when it moves to the point where the first linkage 11 abuts against the second linkage 12. That is, the first abutting part 1121 moves outward to abut against the second plate 1212, driving the second plate 1212 to move outward, thereby driving the inner door 3 to move outward.

[0102] The process of switching the door assembly 300 from the open state to the closed state is as follows: The outer door 2 is configured to drive the inner door 3 to close when it moves to the point where the first linkage 11 abuts against the second linkage 12. That is, the second abutting part 1122 moves inward to abut against the abutting block, driving the abutting block to move inward, thereby driving the inner door 3 to move inward until the inner door 3 is closed. At this time, the outer door 2 is not subject to external force, but is subject to the restoring force of the reset device 4, and returns to the front panel plane of the washing machine 100.

[0103] The washing machine 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the washing machine 100 to perform corresponding operations, thereby realizing intelligent control of the washing machine 100 and improving the user experience.
