[0029] The embodiment of the present application provides a door assembly 1 for a washing machine, the door assembly 1 includes a base 10, a shield assembly 20 and a drive assembly 30. The base 10 can be used as a basic component for installing the shield assembly 20 and the drive assembly 30, the base 10 is provided with a clothing inlet 110, and the base 10 includes a first side 11 and a second side 12 arranged oppositely. The shield assembly 20 is used to shield the clothing inlet 110 during the process of the washing machine processing the clothes to ensure the safety of the use process, the shield assembly 20 includes a reel 21 and a rolling door cover 22, the reel 21 is rotatably arranged on the first side 11 of the base 10, the rolling door cover 22 can be a flexible component made of any one of sound-absorbing materials such as organic fiber, inorganic fiber, inorganic foam, and foam plastic to absorb the noise generated by the door assembly 1 during use, and the rolling door cover 22 includes a first end and a second end oppositely, the first end of the rolling door cover 22 is connected to the reel 21, and the reel 21 can be wound around the rolling door cover 22. The driving component 30 is a component for driving the mask component 20 to move, and is used to make the mask component 20 cover the clothing delivery port 110 or to expose the clothing delivery port 110. The driving component 30 includes a motor 31 and an elastic element 32. The motor 31 is installed on the base 10 and is connected to the reel 21, and is used to drive the reel 21 to wind up the rolling door cover 22 to expose the clothing delivery port 110. One end of the elastic element 32 is connected to the second side 12 of the base 10, and the other end of the elastic element 32 is connected to the second end of the rolling door cover 22, and is used to pull the rolling door cover 22 to cover the clothing delivery port 110.
[0030] The rolling door cover 22 provided in the embodiment of the present application can respectively cover and reveal the clothing opening 110 by pulling and rolling up the rolling door cover 22, thereby effectively avoiding the problem of fingers being pinched by the door body. By installing the motor 31 on the base 10 and connecting the reel 21, the motor 31 can drive the reel 21 to rotate so that the reel 21 can roll up the rolling door cover 22, thereby revealing the clothing opening 110. By connecting one end of the elastic element 32 to the second side 12 of the base 10 and the other end of the elastic element 32 to the second end of the rolling door cover 22, the rolling door cover 22 can be pulled to cover the clothing opening 110, thereby allowing the door cover 22 to keep covering the clothing opening 110, thereby improving the convenience and user experience.
[0031] See also Figure 3 and Figure 4 , Figure 3 A schematic cross-sectional view of a door assembly 1 provided in an embodiment of the present application. Figure 4 A schematic diagram of the structure of the base 10 provided in an embodiment of the present application. In some embodiments, the door assembly 1 further includes a control panel 40, which is used as a human-computer interaction component and can be disposed on the second side 12 of the base 10. The second side 12 of the base 10 can be provided with a plurality of control buttons 41 electrically connected to the control panel 40. The user can control the movement state of the motor 31 by manipulating the control buttons 41. The control panel 40 is electrically connected to the motor 31 to control the rotation of the motor 31 or to control the locking of the motor 31. The door assembly 1 can further include a limiting element 50, which can be disposed on the first side 11 and located on the side of the first side 11 facing the second side 12. The limiting element 50 is also electrically connected to the motor 31. The limiting element 50 is triggered by the second end of the rolling door cover 22 during the process of the roller 21 winding the rolling door cover 22, so that the motor 31 locks the roller 21. For example, in some embodiments, the base 10 also includes a first edge 13 and a second edge 14, which are arranged opposite to each other and connected between the first side 11 and the second side 12. A limiting element 50 may be provided at each end of the first side 11 close to the first edge 13 and the second edge 14. The limiting element 50 is electrically connected to the motor 31. The limiting element 50 is triggered by the second end of the rolling door cover 22 during the process of the roller 21 winding the rolling door cover 22, so that the motor 31 locks the roller 21.
[0032] Specifically, the control panel 40 is also electrically connected to the limiting element 50, so that after the limiting element 50 is triggered, a first electrical signal can be immediately sent to the control panel 40. The control panel 40 can output a first response to the motor 31 according to the first electrical signal. After the motor 31 obtains the first response, it will control the motor shaft to be in a locked state. In the locked state, the motor shaft itself cannot rotate, resulting in the inability to drive the reel 21 to rotate, and the reel 21 and the motor 31 shaft cannot rotate under the traction of the elastic element 32 on the rolling door cover 22. That is, in this case, the rotational freedom of the reel 21 is limited, and the reel 21 is in a state where it cannot rotate. When the user inputs a second electrical signal by using the control panel 40, the control panel 40 outputs a second response to the motor 31 according to the second electrical signal. After the motor 31 obtains the second electrical signal, the locked state of the motor shaft is released. In this case, the reset elastic force generated by the elastic element 32 can pull the rolling door cover 22 to cover the clothing delivery port 110. At the same time, the reel 21 and the motor shaft will rotate due to the traction of the rolling door cover 22.
[0033] To facilitate understanding of the technical solution of the embodiment of the present application, the following schematic description and introduction of the use and operation process of the washing machine provided with the door assembly 1 of the embodiment of the present application is made. In the door assembly 1 provided by the embodiment of the present application, when the rolling door cover 22 is wound on the reel 21, the elastic element 32 is in a stretched state, so the elastic element 32 can accumulate elastic potential energy to generate a reset elastic force that pulls the rolling door cover 22 to cover the clothing delivery port 110. The elastic potential energy of the elastic element 32 will gradually increase during the process of the reel 21 winding the rolling door cover 22, so that the reset elastic force of the elastic element 32 gradually increases, and reaches a maximum value when the rolling door is completely wound on the reel 21 so that the clothing delivery port 110 is fully exposed. When the motor 31 shaft is unlocked, the reel 21 and the motor shaft are in a rotatable free state, and the second end of the rolling door cover 22 will approach the second side 12 of the base 10 under the reset elastic force of the elastic element 32, thereby achieving the purpose of covering the clothing delivery port 110. Exemplarily, if the front rolling door cover 22 is used to cover the clothing inlet 110, in order to put the clothes to be processed into the washing machine, the user can use the control panel 40 to control the motor 31 to rotate. When the motor 31 rotates, it drives the reel 21 to wind up the rolling door cover 22, so that the clothing inlet 110 is exposed. During the process of the reel 21 winding up the rolling door cover 22, the elastic element 32 continues to accumulate elastic potential energy until the second end of the rolling door cover 22 triggers the limiting element 50, and then the control panel 40 controls the motor 31 to stop driving the reel 21 to rotate. At this time, the motor shaft is in a locked state under the control of the control panel 40, so that the clothes to be processed can be conveniently put into the washing machine from the clothing inlet 110. Thereafter, the control panel 40 is used to control the motor 31 to release the locked state of the motor shaft. The second end of the rolling door cover 22 will approach the second side 12 of the base 10 under the action of the reset elastic force of the elastic element 32, so that the rolling door cover 22 is in a covering state, thereby ensuring safe operation.
[0034] In some embodiments, the limit element 50 can be a contact switch such as a travel switch. The travel switch can be a touch switch or a micro switch. The travel switch can be arranged on the base 10. Accordingly, the second end of the rolling door cover 22 is provided with a stop block (not shown in the figure). When the reel 21 rolls up the rolling door cover 22, the stop block can approach and trigger the travel switch. Specifically, in the process of the reel 21 rolling up the rolling door cover 22, the second end of the rolling door cover 22 can gradually approach and finally abut against the travel switch as the reel 21 rolls up the rolling door cover 22. After the travel switch is triggered, a first electrical signal is immediately transmitted to the control panel 40. The control panel 40 obtains an analysis result based on the first electrical signal and outputs a first response to the motor 31 based on the analysis result. The motor 31 outputs an execution result based on the first response to control the motor 31 to be in a locked state, ensuring that the clothing delivery port 110 is exposed to facilitate the putting in and taking out of clothing. It is understandable that the limit element 50 can also be an inductive switch such as a Hall sensor or an infrared sensor. Taking the Hall sensor as an example, the Hall sensor can be arranged on the base 10. Accordingly, a magnet is arranged at the second end of the rolling door cover 22. When the reel 21 rolls up the rolling door cover 22, the magnet can approach and trigger the Hall sensor. Specifically, the Hall sensor can be oriented toward the side of the rolling door cover 22 parallel to its movement direction. Accordingly, a magnet can be fixed on the side of the rolling door cover 22 in its movement direction. In the process of the reel 21 rolling up the rolling door cover 22, the rolling door cover 22 The second end of can gradually approach and eventually make the magnet face the Hall sensor as the roller 21 winds up the rolling door cover 22. When the magnet faces the Hall sensor, the Hall sensor senses the change of the magnetic field around it and converts the sensed change into a first electrical signal and transmits it to the control panel 40. The control panel 40 obtains an analysis result based on the first electrical signal and sends a first response to the motor 31 based on the analysis result. The motor 31 outputs an execution result based on the first response to control the motor 31 to be in a locked state, thereby ensuring that the clothing loading port 110 is exposed to facilitate the putting in and taking out of clothing.
[0035] The elastic element 32 is connected between the second side 12 of the base 10 and the second end of the rolling door cover 22, so that the elastic element 32 can be stretched and elastically deformed during the process of the roller 21 winding the rolling door cover 22, so that after the motor 31 is unlocked, the second end of the rolling door cover 22 can move toward the second side 12 of the base 10 under the action of the restoring elastic force of the elastic element 32, and finally the rolling door cover 22 covers the clothing inlet 110.
[0036] In some embodiments, the elastic element 32 may include a coil spring, a positioning shaft 121 is provided on the second side 12 of the base 10, the coil spring is wound around the positioning shaft 121, one end of the coil spring is fixed to the positioning shaft 121, and the other end of the coil spring is connected to the second end of the rolling door cover 22. Alternatively, the elastic element 32 may also be a spring (not shown), each of which may have a connecting end, and the two connecting ends of the spring are respectively connected to the second side 12 of the base 10 and the second end of the rolling door cover 22, thereby achieving the same function and effect as the coil spring. This specification takes the coil spring as an example to schematically describe the implementation process of the coil spring pulling the second end of the rolling door cover 22 toward the second side 12 of the base 10 to cover the clothing delivery port 110. As for the implementation process of using the spring, reference may be made to the relevant description of the coil spring in this specification.
[0037] Specifically, during the process of the reel 21 winding up the rolling shutter door cover 22, the coil spring is stretched, and the distance between two adjacent layers in the coil spring gradually decreases. The coil spring accumulates elastic potential energy, thereby generating a movement tendency that enables the reel 21 to rotate in the opposite direction. For the convenience of explanation, the direction in which the reel 21 rotates under the drive of the motor 31 is referred to as the first rotation direction, and the direction in which the reel 21 rotates under the drive of the return elastic force of the coil spring is referred to as the second rotation direction. When the reel 21 rotates in the first rotation direction to wind up the rolling shutter door cover 22, the reel 21 rotates in the second rotation direction. When the motor 31 rotates, the coil spring will continuously accumulate elastic potential energy due to continuous stretching, until the clothing inlet 110 is fully exposed, the elastic potential energy accumulated by the coil spring is the largest, and the return elastic force of the coil spring is the largest. When the motor 31 is unlocked, the coil spring will release the elastic potential energy and generate the return elastic force. Under the action of the return elastic force, the coil spring will be wound around the positioning shaft, so that the second end of the rolling door cover 22 approaches the second side 12 of the base 10 under the traction of the coil spring, so that the rolling door cover 22 covers the clothing inlet 110. The embodiment of the present application effectively solves the problem of pinching hands by using a flexible rolling door cover 22, and improves the convenience and user experience by using an elastic element 32 to pull the rolling door cover to cover the clothing inlet 110.
[0038] Please continue reading Figure 3 and Figure 4In order to reduce the friction resistance during the movement of the rolling door cover 22 and enable the rolling door cover 22 to perform directional movement in a desired direction, the first side 13 and the second side 14 of the base 10 facing the rolling door cover 22 may each be provided with a guide structure 15 extending along the movement direction of the rolling door cover 22 and connected between the first side 11 and the second side 12, and the rolling door cover 22 is provided with a guide wheel 221 facing the first side 13 and the second side 14, respectively, and the guide wheel 221 is rotatably provided on the rolling door cover 22 and rollingly connected to the guide structure 15, so that the rolling door cover 22 can only move along the extension direction of the guide structure 15. The embodiment of the present application not only reduces the friction force during the movement of the rolling door cover 22, but also improves the directional and stable movement of the rolling door cover 22, which is conducive to reducing the interference between the two sides of the rolling door cover 22 and the two sides of the base 10.
[0039] In some embodiments, the guide structure 15 may include a guide groove, and the guide wheel 221 may include a roller, which is rollingly arranged in the guide groove. Specifically, a guide groove may be provided on the first side 13 and the second side 14 of the base 10 facing the side of the rolling door cover 22, and each guide groove is extended along the movement direction of the rolling door cover 22. Accordingly, a roller may be provided on each side of the rolling door cover 22 facing the two sides of the base 10, and each roller may be rollingly arranged in each guide groove. Since a rolling fit is formed between the roller and the guide groove and the roller can only move along the guide groove, the friction between the door cover 22 and the base 10 when the rolling door cover 22 moves and the jamming between the door cover 22 and the base 10 can be effectively reduced. It is understandable that in one of the replaceable embodiments, replacing the roller provided on the door cover 22 with a ball bearing can also achieve the same technical effect. In another replaceable embodiment, the guide structure 15 may include a rack (not shown), and the guide wheel 221 may include a gear (not shown), and the gear is meshed with the rack. Specifically, a rack may be provided on each side of the first side 13 and the second side 14 of the base 10 facing the rolling door cover 22, and each rack is extended along the movement direction of the rolling door cover 22. Correspondingly, a gear may be provided on each side of the rolling door cover 22 facing both sides of the base 10, and each gear may be rollingly meshed with each rack. Since a rolling fit is formed between the gear and the rack and the gear can only move along the rack, the friction between the door cover and the base 10 when the rolling door cover 22 moves can be effectively reduced, and the jamming between the door cover and the base 10 can be reduced. In another replaceable embodiment, the guide wheel 221 may be arranged at the second end of the rolling door cover 22, and the limiting element 50 may be arranged at one end of the guide structure 15 close to the reel 21. When the reel 21 rolls up the rolling door cover 22, the guide wheel 221 can follow along the guide structure 15 to approach the limiting element 50 and finally trigger the limiting element 50, thereby ensuring that the limiting element 50 can be accurately triggered. In this embodiment, the guide wheel 221 acts as a block. In this case, there is no need to additionally set up the guide wheel 221, which is beneficial to reduce the use of components and simplify the structure of the door body assembly 1.
