[0024] The first aspect of this application discloses a gate assembly 10, which, in some embodiments, is combined with Figures 1 to 5 As shown, the door assembly 10 includes a door body 100, a mounting plate 200, and a cleaning component 300. The mounting plate 200 is disposed on the front side of the door body 100 and has a first region 221 on the side of the mounting plate 200 facing the door body 100. The mounting plate 200 is adapted to move relative to the door body 100 in a first direction when the door body 100 is opened, so that the first region 221 is exposed. The mounting plate 200 is adapted to return to its original position relative to the door body 100 in a second direction opposite to the first direction when the door body 100 is closed, so that the first region 221 is hidden. The cleaning component 300 is disposed on the door body 100 and adapted to abut against the first region 221 to scrape the first region 221 when the door body 100 is opened and closed. With the cleaning component 300, the cleaning component 300 can scrape the first area 221 when the door 100 is opened and closed, which makes it easier to clean the dirt that falls on the first area 221 and plays a self-cleaning role, which to a certain extent prevents dirt from accumulating between the hanging plate 200 and the door 100.

[0025] The door assembly 10 will be described in detail using a dishwasher as an example. The dishwasher includes a body 20 and a door assembly 10. The body 20 forms a washing chamber 400, which is used to hold tableware, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks. The dishwasher can clean the tableware in the washing chamber 400. One side of the washing chamber 400 is open, for example, the front side of the washing chamber 400 is open. The door assembly 10 includes a door 100, which is movably connected to the body 20, typically designed to be rotatable, thereby allowing the washing chamber 400 to be opened and closed (i.e., the movement of the door 100 enables the door 100 to have the functions of opening and closing the washing chamber 400). When the door 100 is open, tableware can be placed into or removed from the washing chamber 400. When cleaning the tableware, the door 100 needs to be closed.

[0026] See Figure 1 and Figure 2 As shown in the diagram, the bottom of the door 100 and the body 20 are rotatably connected (the orientation is based on the door 100 being in the closed state). The door 100 is vertically positioned when the washing chamber 400 is closed, and horizontally positioned when the washing chamber 400 is open. The door 100 rotates downward and forward from the state of the closed washing chamber 400 to switch to the state of the open washing chamber 400, and rotates upward and backward from the state of the open washing chamber 400 to switch to the state of the closed washing chamber 400. The following description will use this as an example.

[0027] When the dishwasher is a built-in dishwasher, the dishwasher body 20 needs to be embedded in the cabinet. In order to make the exposed side of the dishwasher (i.e., the door assembly 10) consistent with the style of the cabinet, a hanging plate 200 is often provided on the door body 100 (i.e., the door assembly 10 includes the hanging plate 200). The hanging plate 200 is located on the front side of the door body 100. The material and design style of the hanging plate 200 are similar to or consistent with the cabinet, thus ensuring the design unity of the kitchen.

[0028] Normally, the mounting plate 200 is closer to the ground than the door 100 to ensure obstruction of the door 100 and the machine body 20. However, when the door 100 is rotated downwards and forwards to open the washing chamber 400, the mounting plate 200 may interfere with the ground. To prevent this interference, the mounting plate 200 and the door 100 are linked. When the door 100 is rotated downwards and forwards to open the washing chamber 400, the mounting plate 200 moves relative to the door 100 in a direction away from the bottom of the door 100 (i.e., from the bottom to the top of the door 100). The movement of the mounting plate 200 (i.e., along the first direction) avoids interference between the mounting plate 200 and the ground. When the door 100 is rotated upwards and backwards to close the washing chamber 400, the mounting plate 200 moves relative to the door 100 in the direction toward the bottom of the door 100 (i.e., along the direction from the top to the bottom of the door 100, i.e., along the second direction). This ensures that the mounting plate 200 is as close to the ground as possible. The cooperation between the mounting plate 200 and the door 100 is known in the prior art. For specific solutions, please refer to the prior art. It will not be described in detail here.

[0029] When the door 100 opens the washing chamber 400, the hanging plate 200 moves relative to the door 100 in a first direction, and at least a portion of the hanging plate 200 protrudes relative to the top of the door 100, thus exposing at least a portion of the hanging plate 200 on the side facing the door 100. The exposed portion is defined as the first region 221. When the door 100 closes the washing chamber 400, the hanging plate 200 moves relative to the door 100 in a second direction to reset, and the hanging plate 200 gradually retracts until it is flush with the top of the door 100, thus hiding the first region 221. That is, at this time, the first region 221 is directly opposite the door 100.

[0030] Understandably, when dirty dishes are placed into the washing chamber 400, the door 100 needs to be in the open state of the washing chamber 400. At this time, the first area 221 is exposed, that is, the first area 221 can be observed from top to bottom. During the process of placing the dishes into the washing chamber 400, the residue, juice and other dirt on the dishes may fall into the first area 221. Since the first area 221 is hidden when the door 100 closes the washing chamber 400, dirt and grime are trapped between the hanging plate 200 and the door 100, which is not easy to clean.

[0031] Therefore, in this embodiment, the door assembly 10 further includes a cleaning component 300. The cleaning component 300 is disposed on the door body 100 and is used to abut against the first area 221. Thus, when the door body 100 is opened and closed, the cleaning component 300 scrapes the first area 221 to achieve self-cleaning of the first area 221, thereby preventing dirt and grime from accumulating between the hanging plate 200 and the door body 100 to a certain extent.

[0032] Specifically, the cleaning component 300 can be fixedly installed on the door 100. The cleaning component 300 is stationary relative to the door 100. When the door 100 switches from the state of opening the washing chamber 400 to the state of closing the washing chamber 400, the hanging plate 200 moves relative to the door 100 in the second direction to reset. That is, at this time, the hanging plate 200 moves relative to the cleaning component 300. The cleaning component 300 abuts against the first area 221. During the reset process of the hanging plate 200, the cleaning component 300 scrapes the first area 221. As the hanging plate 200 resets in the second direction, the top edge of the hanging plate 200 gradually approaches the cleaning component 300. Through the action of the cleaning component 300, dirt can be pushed towards the top edge of the hanging plate 200, thereby facilitating cleaning by the user and preventing dirt from being deeply hidden between the hanging plate 200 and the door 100, which would cause dirt to accumulate between the hanging plate 200 and the door 100.

[0033] In addition to being fixedly mounted on the door 100 and stationary relative to the door 100, the cleaning component 300 can also be linked with the door 100. That is, the cleaning component 300 can be designed to move synchronously relative to the door 100 when the door 100 is opened and closed. The moving speed of the cleaning component 300 is different from the moving speed of the hanging plate 200 (the moving speed of the cleaning component 300 relative to the door 100 is faster or slower than the moving speed of the hanging plate 200 relative to the door 100), or the moving direction of the cleaning component 300 is opposite to the moving direction of the hanging plate 200. This can also achieve the scraping of the first area 221. However, compared with the solution of fixing the cleaning component 300 on the door 100, the linkage between the cleaning component 300 and the door 100 is slightly more complicated.

[0034] In some embodiments, combined with Figures 2 to 8 As shown, the door 100 includes a main body 110 and a top control panel 120 disposed on the main body 110 (with the orientation of the door 100 in the closed washing chamber 400 as a reference). The cleaning component 300 is disposed on the control panel 120 and is located between the hanging plate 200 and the control panel 120.

[0035] The control panel 120 is a component for user input to control the operation of the dishwasher. It includes a frame and electronic components mounted on the frame. The frame forms the supporting skeleton for the electronic components. The main body 110 constitutes most of the door 100. The frame of the control panel 120 and the main body 110 are connected to assemble the control panel 120 and the main body 110 together. The control panel 120 is located at the top of the main body 110, thus placing it in a relatively high position for easy user control. The cleaning component 300 is positioned on the control panel 120, making it relatively close to the top edge of the door 100. Optionally, the cleaning component 300 can be installed on the control panel 120 using various methods, including but not limited to adhesive, snap-fit, screws, and clamping.

[0036] In some embodiments, the distance between the cleaning component 300 and the top edge of the door 100 is no greater than 10 cm. See [reference needed]. Figure 3 As shown, the distance between the cleaning component 300 and the top edge of the door 100 (i.e., the top edge of the control panel 120) is H, which is no greater than 10cm. During the process of the mounting plate 200 resetting in the second direction, the top edge of the mounting plate 200 gradually approaches the cleaning component 300. The cleaning component 300 can push dirt towards the top edge of the mounting plate 200. By optimizing the distance between the cleaning component 300 and the top edge of the door 100, the dirt pushed by the cleaning component 300 is as close as possible to the top edges of the mounting plate 200 and the door 100, making it more convenient for the user to clean.

[0037] In some embodiments, combined with Figure 6 and Figure 7 As shown, the cleaning component 300 extends along the left and right directions of the door 100. With the user standing in front of the dishwasher, the side of the dishwasher corresponding to the user's left hand is considered left, and the side corresponding to the user's right hand is considered right. The front of the washing chamber 400 is open. The door 100 rotates downwards and forwards from the closed state to open the washing chamber 400, and rotates upwards and backwards from the open state to close the washing chamber 400. Because the cleaning component 300 extends along the left and right directions of the door 100, while effectively scraping the first area 221, it helps to reduce the space occupied and volume of the cleaning component 300. For example, the cleaning component 300 can extend linearly along the left and right directions of the door 100.

[0038] In some embodiments, the cleaning component 300 includes a brush protruding from the side of the door 100 facing the hanging plate 200. The cleaning component 300 is adapted to abut against the first area 221 via the brush. Since the cleaning component 300 needs to abut against the first area 221, relative sliding occurs between the cleaning component 300 and the hanging plate 200 as the hanging plate 200 moves relative to the door 100. In this embodiment, the cleaning component 300 includes a soft and deformable brush. By abutting against the first area 221 via the brush, both scraping of the first area 221 can be ensured, and noise can be avoided when the hanging plate 200 moves relative to the door 100.

[0039] In some embodiments, combined with Figure 4 , Figure 5 , Figures 9 to 11 As shown, the side of the hanging plate 200 facing the door body 100 is provided with a flow guide groove 222. The flow guide groove 222 is adapted to receive liquid flowing from top to bottom, and the flow guide groove 222 extends to the left edge and / or right edge of the hanging plate 200 to guide the received liquid to the left edge and / or right edge of the hanging plate 200.

[0040] As mentioned above, the dirt falling into the first area 221 includes liquids such as juices. The scraping effect of the cleaning component 300 on liquids may be relatively weak, and liquid is easily left in the first area 221, especially when the cleaning component 300 scrapes the first area 221 with a brush. Therefore, in this embodiment, the side of the hanging plate 200 facing the door 100 is provided with a guide channel 222, which is suitable for receiving liquid flowing from top to bottom. When the door 100 closes the washing chamber 400, the guide channel 222 is located below the first area 221. The guide channel 222 may extend only to the left edge of the hanging plate 200, or only to the right edge of the hanging plate 200, or simultaneously to both the left and right edges of the hanging plate 200. Liquid flows downward along the first area 221 and enters the guide channel 222, and then flows along the guide channel 222 to the left and / or right edges of the hanging plate 200, thereby facilitating cleaning by the user.

[0041] In some embodiments, when the flow channel 222 extends to both the left and right edges of the mounting plate 200, the flow channel 222 includes a first flow channel 2221 and a second flow channel 2222 that intersect and communicate with each other. The first flow channel 2221 extends to the left edge of the mounting plate 200, and the second flow channel 2222 extends to the right edge of the mounting plate 200. When the door 100 is in the closed state, the first flow channel 2221 and the second flow channel 2222 extend away from each other and tilt downwards. In this way, the liquid can be guided to the left and right edges of the mounting plate 200, and the space occupied by the flow channel 222 can also be compressed.

[0042] In some embodiments, combined with Figures 9 to 11 As shown, the mounting plate 200 includes a mounting plate body 210 and a cover plate 220 disposed on the mounting plate body 210. The cover plate 220 has a first region 221 and a guide groove 222 formed on the side facing the door body 100.

[0043] In this embodiment, the mounting plate 200 includes a mounting plate body 210 and a cover plate 220. The mounting plate body 210 constitutes most of the structure of the mounting plate 200 and is linked to the door 100. The cover plate 220 is disposed on the inner side of the mounting plate body 210 and has a first area 221 and a guide channel 222. The cover plate 220 is used to collect dirt. The design of the cover plate 220 of the mounting plate body 210 can be considered separately. For example, the mounting plate body 210 can be designed mainly to match the design style of the cabinet, while the cover plate 220 can be designed mainly to collect dirt. This makes the design of the mounting plate 200 more flexible.

[0044] Optionally, the cover plate 220 is located inside the mounting plate body 210, and the side of the cover plate 220 facing the door 100 is set with a glossy surface. With this setting, when the first area 221 is scraped by the cleaning component 300, the first area 221 is less likely to form residue. For example, the cover plate 220 can be made of metal material, which is easy to form a glossy structure.

[0045] The second aspect of this application discloses a dishwasher, combined with Figures 1 to 11 As shown, the dishwasher includes the aforementioned door assembly 10. The door assembly 10 includes a door body 100, a mounting plate 200, and a cleaning component 300. The mounting plate 200 is disposed on the door body 100 and has a first region 221 on the side facing the door body 100. The mounting plate 200 is adapted to move relative to the door body 100 in a first direction when the door body 100 is opened (i.e., when the door body 100 opens the washing chamber 400) so that the first region 221 is exposed. The mounting plate 200 is adapted to return to its original position relative to the door body 100 in a second direction opposite to the first direction when the door body 100 is closed (i.e., when the door body 100 closes the washing chamber 400) so that the first region 221 is hidden. The cleaning component 300 is disposed on the door body 100 and adapted to abut against the first region 221 to scrape the first region 221 when the door body 100 is opened and closed.

[0046] With the cleaning component 300 in place, when the door 100 switches from an open washing chamber 400 state to a closed washing chamber 400 state, the hanging plate 200 moves relative to the door 100 and resets in the second direction. At this time, the hanging plate 200 moves relative to the cleaning component 300, and the cleaning component 300 abuts against the first area 221. During the reset process of the hanging plate 200, the cleaning component 300 scrapes the first area 221. As the hanging plate 200 resets in the second direction, its top edge gradually approaches the cleaning component 300. The cleaning component 300 pushes dirt towards the top edge of the hanging plate 200, making cleaning easier for the user and preventing dirt from accumulating between the hanging plate 200 and the door 100. It is understood that the dishwasher door assembly 10 of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0047] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
