[0034] A fully automatic washing machine has pre-programmed cycles in its microcomputer. To wash, select one of these cycles, turn on the faucet, and start the washing machine. The machine automatically detects and controls the water level, accurately completing the soaking, rinsing, spin, and automatic draining cycles. When the washing cycle is complete, it stops automatically and a buzzer sounds.

[0035] A drum washing machine is a type of fully automatic washing machine. The outer door of the drum washing machine is fixed to the front panel, and the inner door is fixed to the outer drum to seal the outer drum. When putting clothes into the washing machine, you first need to open the outer door 1, then open the inner door, and then put the clothes in. After the clothes are put in, you first close the inner door and then the outer door before the washing machine can start working. This makes it very inconvenient to take clothes out of the washing machine or put clothes into the washing machine, resulting in a poor washing machine user experience.

[0036] In view of this, an embodiment of the present application provides a door cover assembly and a washing machine, which can solve the above-mentioned technical problems.

[0037] Figure 1 A schematic structural diagram of a washing machine provided by an embodiment of the present invention is shown in FIG. Figure 1As shown, in an embodiment of the present application, a door cover assembly is provided, including: an outer door 1, an inner door 2 and a linkage assembly 3; wherein the linkage assembly 3 is respectively connected to the outer door 1 and the inner door 2, so that when the outer door 1 is rotated to open at an angle, the linkage assembly 3 drives the inner door 2 to rotate and open synchronously.

[0038] The door cover assembly provided in the embodiment of the present application includes an outer door 1, an inner door 2, and a linkage assembly 3, wherein both the outer door 1 and the inner door 2 are connected to the linkage assembly 3. When the outer door 1 is rotated to open, the movement generated by the outer door 1 is transmitted to the linkage assembly 3 due to the connection between the outer door 1 and the linkage assembly 3. Since the inner door 2 is also connected to the linkage assembly 3, the linkage assembly 3 drives the inner door 2 to rotate synchronously, thereby achieving synchronous opening of the outer door 1 and the inner door 2. When the outer door 1 is closed, the outer door 1 rotates, and the linkage assembly 3 drives the inner door 2 to rotate synchronously, thereby achieving synchronous closing of the outer door 1 and the inner door 2. Therefore, when it is necessary to put clothes into the washing machine, the outer door 1 is opened, and the inner door 2 opens simultaneously with the opening of the outer door 1. Then, the clothes are put into the washing machine. When closing the door, the outer door 1 is closed, and the inner door 2 closes simultaneously with the closing of the outer door 1. This saves the operation of taking clothes out of the washing machine and putting clothes into the washing machine, that is, it is convenient to take clothes out of the washing machine or put clothes into the washing machine, effectively improving the convenience of using the washing machine and enhancing the user experience of the washing machine.

[0039] Figure 2 A schematic structural diagram of a linkage assembly provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the linkage assembly 3 includes a first connecting assembly 31, a second connecting assembly 32 and a transmission component 33. The first connecting assembly 31 is connected to the outer door 1, and the second connecting assembly 32 is connected to the inner door 2. A transmission component 33 is provided between the first connecting assembly 31 and the second connecting assembly 32 to enable the first connecting assembly 31 and the second connecting assembly 32 to move synchronously.

[0040] The above-mentioned linkage assembly 3 includes a first connecting assembly 31, a second connecting assembly 32 and a transmission component 33, wherein the first connecting assembly 31 is connected to the outer door 1, and the second connecting assembly 32 is connected to the inner door 2, and the first connecting assembly 31 and the second connecting assembly 32 are connected by the transmission component 33, so that when the outer door 1 is opened, the movement generated by the outer door 1 is transmitted to the second connecting assembly 32 via the first connecting assembly 31 and the transmission component 33, so that the second connecting assembly 32 moves synchronously with the first connecting assembly 31. Since the inner door 2 is connected to the second connecting assembly 32, the inner door 2 moves synchronously with the second connecting assembly 32, thereby realizing the synchronous movement of the inner door 2 and the outer door 1. When the clothes need to be put into the washing machine, the outer door 1 is opened, and the inner door 2 is opened at the same time as the outer door 1 is opened, and then the clothes are put into the washing machine. When closing the door, the outer door 1 is closed, and the inner door 2 is closed at the same time as the outer door 1 is closed, which saves the operation of taking out and putting clothes into the washing machine, that is, it is convenient to take clothes out of the washing machine or put clothes into the washing machine, effectively improving the convenience of using the washing machine and improving the user experience of the washing machine.

[0041] Figure 3 A schematic structural diagram of a first connection assembly provided in one embodiment of the present invention is shown. Figure 4 A schematic diagram of the structure of a transmission component provided by an embodiment of the present invention is shown in FIG. Figures 3 and 4 As shown, in some embodiments, the outer door 1 is rotatably connected to the housing 4 of the washing machine through a first connecting component 31, and the inner door 2 is rotatably connected to the outer drum 5 of the washing machine through a second connecting component 32; the first connecting component 31 includes a first hinge shaft 314 and a first turntable 312 fixed to the outer door 1 and coaxial with the first hinge shaft 314; the second connecting component 32 includes a second hinge shaft and a second turntable 322 fixed to the inner door 2 and coaxial with the second hinge shaft, and the second hinge shaft and the first hinge shaft 314 are parallel to each other; the transmission component 33 includes a transmission wire 333 that connects the first turntable 312 and the second turntable 322 and transmits the rotational motion of the first turntable 312 to the second turntable 322.

[0042] In the linkage assembly 3 described above, the first connecting assembly 31 is connected to the washing machine housing 4, and the second connecting assembly is connected to the washing machine's outer drum 5. The first connecting assembly 31 includes a first body 311, a first hinge shaft 314, and a first turntable 312. The first body 311 is connected to the washing machine housing 4, and the first hinge shaft 314 is rotatably connected to the outer door 1. In the embodiment of the present application, the outer door 1 is formed with a first extension portion 11, which is provided with a mating hole. A bearing is sleeved on the outer side of the first hinge shaft 314, and the bearing is disposed in the mating hole to rotatably connect the outer door 1 to the first hinge shaft 314. In other words, the first body 311 is fixedly connected to the first hinge shaft 314. When the outer door 1 rotates, the mating hole rotates about the axis of the first hinge shaft 314, thereby enabling the outer door 1 to rotate relative to the housing 4.

[0043] The second connecting assembly 32 has the same structure as the first connecting assembly 31. Specifically, it includes a second body 321, a second hinge shaft, and a second turntable 322. The second body 321 is connected to the outer drum 5 of the washing machine. Furthermore, the inner door 2 is formed with a second extension 21, which is provided with a mating hole. A bearing is sleeved on the outer side of the second hinge shaft, which is seated in the mating hole to enable rotational connection between the inner door 2 and the second hinge shaft. In other words, the second body 321 is fixedly connected to the second hinge shaft. When the inner door 2 rotates, the mating hole in the inner door 2 rotates about the axis of the second hinge shaft, thereby enabling rotation of the inner door 2 relative to the outer drum 5.

[0044] In addition, the first turntable 312 is fixedly connected to the outer door 1, and the second turntable 322 is fixedly connected to the inner door 2. When the outer door 1 rotates, the first turntable 312 rotates synchronously with the outer door 1. Since the transmission wire 333 is respectively connected to the first turntable 312 and the second turntable 322, the transmission wire 333 transmits the force generated by the rotation of the first turntable 312 to the second turntable 322, causing the second turntable 322 to rotate, thereby driving the inner door 2 to rotate, thereby realizing the synchronous rotation of the inner door 2 and the outer door 1.

[0045] like Figure 4 As shown, in some embodiments, the transmission component 33 includes a first connection end 331 , a second connection end 332 and a transmission wire 333 , the first connection end 331 is connected to the first turntable 312 , and the second connection end 332 is connected to the second turntable 322 .

[0046] The transmission wire 333 is provided with a first connecting end 331 and a second connecting end 332 at both ends. The first connecting end 331 is fixedly connected to the first rotary disk 312, and the second connecting end 332 is fixedly connected to the second rotary disk 322. In this embodiment, the outer circumferences of the first rotary disk 312 and the second rotary disk 322 are both provided with grooves for winding the transmission wire 333. A first clamping groove is provided on one side of the first rotary disk 312, and a second clamping groove is provided on one side of the second rotary disk 322. The first connecting end 331 of the transmission component 33 is clamped with the first clamping groove, and the second connecting end 332 is clamped with the second clamping groove, so as to ensure a stable connection between the transmission wire 333, the first rotary disk 312, and the second rotary disk 322. When the first rotary disk 312 rotates, the force generated by the rotation is promptly and effectively transmitted to the second rotary disk 322, thereby ensuring synchronous transmission of the second rotary disk 322 with the first rotary disk 312.

[0047] In some embodiments, the transmission wire 333 includes a first transmission wire 333a and a second transmission wire 333b, which surround the first rotation disk 312 and the second rotation disk 322 respectively, so that the first rotation disk 312 and the second rotation disk 322 are located between the first transmission wire 333a and the second transmission wire 333b.

[0048] That is, in this embodiment, the first transmission wire 333a and the second transmission wire 333b are connected by the first connecting end 331 and the second connecting end 332 to form a closed annular structure. Since the first connecting end 331 is connected to the first turntable 312 and the second connecting end 332 is connected to the second turntable 322, the first turntable 312 and the second turntable 322 are located within the annular structure of the transmission wire 333. When the outer door 1 is opened, the outer door 1 drives the first turntable 312 to rotate, and the first transmission wire 333a rotates around the outer circumference of the first turntable 312 in the direction of rotation of the first turntable 312. As the unwound portion of the first transmission wire 333a gradually shortens, the second turntable 322 is subjected to a force moving toward the first turntable 312, causing the second turntable 322 to rotate about its own axis, thereby driving the inner door 2 to rotate. At this time, the second transmission wire 333b is wound around the outer circumference of the second turntable 322.

[0049] When the outer door 1 is closed, the outer door 1 drives the first turntable 312 to rotate. The rotation direction at this time is opposite to the rotation direction when the outer door 1 is opened. The first rotating wire wrapped around the outer periphery of the first turntable 312 is released, and the second transmission wire 333b is gradually wrapped around the outer periphery of the first turntable 312, so that the force of the first transmission wire 333a on the second turntable 322 is reduced, and the force of the second transmission wire 333b on the second turntable 322 is increased, so that the second turntable 322 rotates, and the rotation direction of the inner door 2 when closed is opposite to that when opened.

[0050] Specifically, the transmission wire 333 includes a steel wire rope.

[0051] The transmission wire 333 is a steel wire rope, which has good strength and flexibility, and a small elastic coefficient, and can realize the transmission of motion quickly and efficiently.

[0052] Optionally, two first turntables 312 are provided on the outer door 1 along the extension direction of the first hinge axis 314, and two second turntables 322 are provided on the inner door 2 along the extension direction of the second hinge axis. The two first turntables 312 and the two second turntables 322 are respectively connected by transmission wires 333.

[0053] In the above-mentioned first connecting component 31, along the extension direction of the first hinge axis 314, a first turntable 312 is respectively provided at both ends of the first body 311, and in the second connecting component 32, a second turntable 322 is respectively provided at both ends of the second body 321. The two first turntables 312 and the two second turntables 322 are respectively connected by transmission wires 333, thereby ensuring that the force generated when the outer door 1 rotates is stably transmitted to the second rotation, ensuring that the inner door 2 is evenly stressed, and preventing the inner door 2 from getting stuck during the rotation process.

[0054] In addition, the first body 311 is provided with a first mounting seat 313 for installing the first turntable 312, and the second body 321 is provided with a second mounting seat 323 for installing the second turntable 322. The first turntable 312 is rotatably connected to the first mounting seat 313, and the second turntable 322 is rotatably connected to the second mounting seat 323. By providing the first mounting seat 313 and the second mounting seat 323, the stability of the installation of the first turntable 312 and the second turntable 322 is guaranteed, thereby ensuring the structural stability of the first connecting component 31 and the second connecting component 32.

[0056] like Figures 5 to 8 As shown, in other embodiments, the linkage assembly 3 includes a guide post 6 provided on the surface of the inner door 2 facing the outer door 1 and a slide groove 12 provided on the outer door 1 , and the guide post 6 is slidably connected to the slide groove 12 .

[0057] The inner door 2 is provided with a guide post 6 that passes through the outer door to achieve coordination with the outer door. When the outer door is opened, the outer door acts on the guide post 6, causing the guide post 6 to move with the outer door in a direction away from the washing machine, thereby driving the inner door 2 to open synchronously with the outer door. When the outer door is closed, the outer door pushes the guide post 6 toward the outer tub 5, causing the guide post 6 to move with the outer door in a direction toward the outer tub 5, thereby driving the inner door 2 to close synchronously with the outer door. During the process of opening or closing the outer and inner doors 2, the relative position between the outer and inner doors 2 changes. Therefore, a slide groove 12 is provided on the outer door to allow the guide post 6 to slide along the slide groove 12 during the relative position change of the outer and inner doors 2. This prevents the outer and inner doors 2 from getting stuck during the opening or closing process and ensures that the outer and inner doors 2 can open to a larger angle.

[0058] Specifically, the guide column 6 includes a guide rod 61, on which a first limit block 62 having an outer circumferential width greater than the width of the slide groove 12 is provided. The guide rod 61 extends through the slide groove 12 to the side of the outer door away from the inner door 2, and the first limit block 62 is located on the side of the outer door away from the inner door 2.

[0059] In addition, a second limit block with an outer circumferential width greater than the width of the sliding groove 12 is provided on the guide rod 61 , and the second limit block is located on the side of the outer door facing the inner door 2 .

[0060] The guide rod 61 is provided with a first stopper and a second stopper to ensure that the inner door 2 moves synchronously when the outer door is opened or closed. Specifically, when the outer door is opened, the outer door cooperates with the first stopper, which, under the action of the outer door, pushes the first stopper away from the outer cylinder 5, thereby causing the inner door 2 to open synchronously with the outer door. When the outer door is closed, the outer door rotates toward the outer cylinder 5, and the outer door cooperates with the second stopper to push the second stopper toward the outer cylinder 5, thereby causing the outer door and the inner door 2 to close synchronously.

[0061] An embodiment of the present application further provides a washing machine, comprising a housing 4, an outer tub 5 and the above-mentioned door cover assembly.

[0062] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
