Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0052] This application discloses a dishwasher, combined with Figures 1 to 13 As shown, in some embodiments, the dishwasher includes a body 1000, a first door 2100, a second door 2200, a transmission rod 3100, and a locking mechanism 3000. The body 1000 has a washing chamber (not shown in the figure) inside. The first door 2100 is adapted to close and open a portion of the washing chamber. The first door 2100 is locked to the body 1000 when the washing chamber is partially closed. The second door 2200 is linked to the first door 2100 to be adapted to close and open the other portion of the washing chamber. The transmission rod 3100 is disposed on the body 1000. The first door 2100 is adapted to push the transmission rod 3100 when the washing chamber is partially closed. The locking mechanism 3000 is disposed on the body 1000. When the first door 2100 closes a portion of the washing chamber, the locking mechanism 3000 is pushed by the transmission rod 3100 to lock the second door 2200.

[0053] By setting up a transmission rod 3100 and a locking mechanism 3000, when the first door 2100 is closed, in addition to locking with the body 1000, the first door 2100 also pushes the locking mechanism 3000 to lock the second door 2200. In this way, both the first door 2100 and the second door 2200 are effectively locked, ensuring the sealing of the closure.

[0054] The machine body 1000 has a washing chamber inside, in which a dish rack is installed. The dish rack can slide in and out of the washing chamber, facilitating the loading and unloading of tableware. The tableware includes, but is not limited to, washable items such as bowls, plates, cups, pots, knives, forks, and chopsticks. The first door 2100 and the second door 2200 cooperate to open and close the washing chamber; that is, the first door 2100 and the second door 2200 work together to open and close the washing chamber. In this embodiment, the first door 2100 and the second door 2200 are linked, meaning that the movement of the first door 2100 can drive the movement of the second door 2200, or vice versa. For example, the first door 2100 and the second door 2200 are configured to be rotatable. The first door 2100 can rotate to approach the washing chamber to close a part of the washing chamber. When the first door 2100 rotates to approach the washing chamber, it causes the second door 2200 to rotate to approach the washing chamber, causing the second door 2200 to close another part of the washing chamber. The first door 2100 can rotate away from the washing chamber to open a part of the washing chamber. When the first door 2100 rotates away from the washing chamber, it causes the second door 2200 to rotate away from the washing chamber, causing the second door 2200 to open another part of the washing chamber.

[0055] The linkage between the first door 2100 and the second door 2200 can be achieved by setting a linkage hinge 4000. Both the first door 2100 and the second door 2200 are connected to the linkage hinge 4000 and to the body 1000 through the linkage hinge 4000. In this way, the first door 2100 and the second door 2200 can be rotatably set relative to the body 1000 and can be linked through the linkage hinge 4000. That is, when the first door 2100 rotates, it can drive the second door 2200 to rotate through the linkage hinge 4000. They can move synchronously or asynchronously (i.e., they move asynchronously, that is, there is a lag between their movements). The linkage hinge 4000 is not an improvement point of this application. The specific structure of the linkage hinge 4000 can be referred to in related technologies and will not be described in detail here.

[0056] When the first door 2100 is partially closed in the washing chamber, it needs to be locked with the body 1000 to maintain the position of the first door 2100 relative to the body 1000 and ensure the sealing of the first door 2100. The locking between the first door 2100 and the body 1000 can be referred to in related technologies. For example, the first door 2100 includes a first door latch 2110, and the body 1000 is provided with a latch 1230. When the first door 2100 is partially closed in the washing chamber, the first door latch 2110 and the latch 1230 engage, thus locking the first door 2100, that is, achieving the locking between the first door 2100 and the body 1000. The first latch 2110 can engage with the latch 1230 in the following way: the first latch 2110 is rotatable and has a stop slope 2111. When the first door 2100 closes part of the washing chamber, as the first door 2100 approaches the washing chamber, the first latch 2110 abuts against the latch 1230 through the stop slope 2111. The latch 1230 generates a component force on the stop slope 2111, which forces the first latch 2110 to rotate and avoid the latch 1230. As the first door 2100 closes to the end, the first latch 2110 rotates in the opposite direction and engages with the latch 1230. In this way, the latch 1230 blocks the first latch 2110 in the direction in which the first door 2100 leaves the washing chamber, thereby locking the first door 2100.

[0057] Since the second door 2200 and the first door 2100 are linked, the closing of a portion of the washing chamber by the first door 2100 can cause the second door 2200 to close the other portion of the washing chamber. In this embodiment, a locking mechanism 3000 is provided to lock the second door 2200. The locking mechanism 3000 is provided in the machine body 1000. When the first door 2100 closes a portion of the washing chamber, the first door 2100 pushes the transmission rod 3100, thereby causing the transmission rod 3100 to push the locking mechanism 3000, so that the locking mechanism 3000 locks the second door 2200.

[0058] For example, as the first door 2100 rotates closer to the washing chamber, the second door 2200 follows suit. As the first door 2100 closes, it pushes the transmission rod 3100, which in turn pushes the locking mechanism 3000, causing the locking mechanism 3000 to move accordingly and lock the second door 2200. This maintains the position of the second door 2200 relative to the machine body 1000, ensuring the sealing of the second door 2200 when closed. It is understood that the pushing of one component onto another can be direct or indirect, as long as force transmission is achieved.

[0059] Combination Figures 3 to 6 as well as Figures 10 to 13 As shown, in some embodiments, the second door 2200 includes a second door latch 2210, and the locking mechanism 3000 includes a locking block 3200. When the first door 2100 closes the first part of the washing chamber, the first door 2100 pushes the transmission rod 3100, causing the transmission rod 3100 to push the locking block 3200, thereby causing the locking block 3200 and the second door latch 2210 to engage, thus locking the second door 2200.

[0060] Specifically, the transmission rod 3100 and the locking block 3200 are movably mounted on the machine body 1000. When the first door 2100 partially closes the washing chamber, the first door 2100 pushes the transmission rod 3100 (either directly or indirectly). The closing action of the first door 2100 transmits force to the transmission rod 3100, causing it to move. This movement then pushes the locking block 3200, which in turn moves and engages with the second door latch 2210, thus locking the second door 2200. The transmission rod 3100 allows for the strategic placement of the second door latch 2210.

[0061] The transmission rod 3100 and the locking block 3200 can move in various ways, as long as they can change position relative to the machine body 1000 when pushed by the first door body 2100. For example, they can be combined... Figures 1 to 6 As shown, the transmission rod 3100 and the locking block 3200 are configured to be rotatable. When the first door 2100 closes part of the washing chamber, the first door 2100 pushes the transmission rod 3100 to rotate. The rotation of the transmission rod 3100 pushes the locking block 3200 to rotate. The locking block 3200 rotates to engage with the second door latch 2210, thereby locking the second door 2200.

[0062] See Figures 1 to 6In the orientation of the first door body 2100, the first door body 2100 is located below the second door body 2200. The transmission rod 3100 is arranged roughly in the vertical direction, and the middle position of the transmission rod 3100 forms a rotation connection point. For example, the distance between the rotation center of the transmission rod 3100 and one end of the transmission rod 3100 is not less than one-third and not more than two-thirds of the extension length of the transmission rod 3100. This makes the rotation center of the transmission rod 3100 roughly located in the middle position of the transmission rod 3100. When the first door body 2100 rotates clockwise and approaches the washing chamber, the first door body 2100 pushes the bottom of the transmission rod 3100, and the transmission rod 3100 rotates counterclockwise. The top of the transmission rod 3100 pushes the locking block 3200 to rotate clockwise. The second door latch 2210 is in the shape of a downward hook, and the locking block 3200 rotates clockwise to engage with the second door latch 2210.

[0063] When the first door 2100 is partially closed in the washing chamber, it needs to be locked by the engagement of the first door latch 2110 and the latch position 1230. When the first door latch 2110 and the latch position 1230 are engaged, the first door latch 2110 extends into the machine body 1000. Based on this, combined with Figures 1 to 6 As shown, in this embodiment, the first door 2100 also pushes the transmission rod 3100 through the first door latch 2110. That is, while the first door 2100 is locked by engaging with the first door latch 2110 and the latching position 1230, the first door latch 2110 also pushes the transmission rod 3100 to rotate (one end of the first door latch 2110 corresponds to one end of the transmission rod 3100, and the locking block 3200 corresponds to the other end of the transmission rod). Since the movement of the transmission rod 3100 is rotation, as the first door 2100 approaches the washing chamber, regardless of how the engagement action of the first door latch 2110 and the latching position 1230 changes, it can maintain the push on the transmission rod 3100, causing the transmission rod 3100 to rotate. In this way, the first door latch 2110 has the functions of engaging with the latching position 1230 and pushing the transmission rod 3100, which helps to simplify the structure.

[0064] The movement of the transmission rod 3100 and the locking block 3200 can also adopt the following scheme, for example, by combining... Figures 7 to 13 As shown, the transmission rod 3100 is linearly movable, and the locking block 3200 is rotatably movable. When the first door 2100 closes part of the washing chamber, the first door 2100 pushes the transmission rod 3100 to move linearly. The linear movement of the transmission rod 3100 pushes the locking block 3200 to rotate. The locking block 3200 rotates to engage with the second door latch 2210, thereby locking the second door 2200.

[0065] See Figures 7 to 13As shown, the first door 2100 is located below the second door 2200. The transmission rod 3100 can move linearly in the vertical direction. The first door 2100 rotates clockwise to approach the washing chamber. The first door 2100 pushes the bottom of the transmission rod 3100, and the transmission rod 3100 moves linearly from bottom to top. The top of the transmission rod 3100 pushes the locking block 3200 to rotate clockwise. The second door latch 2210 is in the shape of a downward hook. The locking block 3200 rotates clockwise to engage with the second door latch 2210.

[0066] Since the transmission rod 3100 can move linearly, in order to improve the stability of the linear movement of the transmission rod 3100, combined with... Figures 7 to 13 As shown, in some embodiments, the body 1000 is provided with a slide groove 1210, and the transmission rod 3100 is disposed in the slide groove 1210, so that it can move linearly along the extension direction of the slide groove 1210. For example, the slide groove 1210 extends in the vertical direction, and the transmission rod 3100 is slidably disposed in the slide groove 1210. When the transmission rod 3100 moves linearly in the vertical direction, it is restricted and guided by the slide groove 1210, so that the linear movement of the transmission rod 3100 is more stable, ensuring the cooperation with the first door body 2100 and the lock block 3200.

[0067] The following solutions can also be adopted, combined with Figures 7 to 13 As shown, in some embodiments, the body 1000 is provided with guide posts 1220, and the transmission rod 3100 is provided with guide grooves 3110. The guide posts 1220 are inserted into the guide grooves 3110, and the transmission rod 3100 can move linearly along the extension direction of the guide grooves 3110. When the transmission rod 3100 moves linearly, the guide posts 1220, when inserted into the guide grooves 3110, improve the linear movement stability of the transmission rod 3100 through the cooperation of the guide grooves 3110 and the guide posts 1220. For example, the guide grooves 3110 extend in the vertical direction, and two guide posts 1220 are arranged in the vertical direction and inserted into the guide grooves 3110.

[0068] It is understandable that the linear movement stability of the transmission rod 3100 can be improved by both setting the slide groove 1210 and cooperating with the guide groove 3110 and the guide post 1220.

[0069] Combination Figures 7 to 13 As shown, in some embodiments, the first door 2100 includes a first door latch 2110 and a protrusion 2120 spaced apart from each other, and the body 1000 is provided with a latch 1230. The first door latch 2110 is adapted to engage with the latch 1230 to lock the first door 2100 when the first door 2100 closes part of the washing chamber, and the protrusion 2120 is adapted to push the transmission rod 3100 to move linearly when the first door 2100 closes part of the washing chamber.

[0070] When the first door 2100 closes part of the washing chamber, as the first door 2100 approaches the washing chamber, the first door latch 2110 and the latch 1230 engage during the process of engagement, ultimately achieving the engagement of the first door latch 2110 and the latch 1230. Since the transmission rod 3100 can move linearly, if the first door latch 2110 is used to push the transmission rod 3100 to move linearly, the engagement action of the first door latch 2110 may cause the transmission rod 3100 to make excessive linear movement. In this case, the transmission rod 3100 and the locking block 3200 will interfere, increasing the complexity of the structure.

[0071] For example, the first latch 2110 is rotatably configured and has a stop slope 2111. When the first door 2100 closes part of the washing chamber, as the first door 2100 approaches the washing chamber, the first latch 2110 abuts against the latch 1230 through the stop slope 2111. The latch 1230 generates a component force on the stop slope 2111, which forces the first latch 2110 to rotate upward to avoid the latch 1230. As the first door 2100 is closed in place, the first latch 2110 rotates in the opposite direction (downward) to engage with the latch 1230. In this way, the latch 1230 blocks the first latch 2110 in the direction in which the first door 2100 leaves the washing chamber, thereby locking the first door 2100. If the first latch 2110 is used to push the transmission rod 3100 to move linearly, then when the first latch 2110 rotates upward to avoid the latch position 1230, the transmission rod 3100 will make excessive linear movement, causing the transmission rod 3100, the locking block 3200 and the second latch 2210 to interfere with each other.

[0072] Therefore, in this embodiment, based on the linear movement of the transmission rod 3100, a protrusion 2120 is provided. The protrusion 2120 and the first door latch 2110 are spaced apart. The latching action of the first door latch 2110 and the latch position 1230 does not affect the protrusion 2120. As the first door 2100 closes part of the washing chamber, the protrusion 2120 pushes the transmission rod 3100 to move linearly (the locking block 3200 corresponds to one end of the transmission rod 3100, and the protrusion 2120 corresponds to the other end of the transmission rod 3100), thus avoiding excessive linear movement of the transmission rod 3100.

[0073] Generally, the first door 2100 and the second door 2200 are rotatably connected to the body 1000. When the first door 2100 partially closes the washing chamber, the protrusion 2120 rotates along an arc-shaped path. To convert the rotation of the protrusion 2120 into linear movement of the transmission rod 3100, the protrusion 2120 is provided with a first guide slope 2121. The first guide slope 2121 is adapted to abut against the transmission rod 3100 when the first door 2100 partially closes the washing chamber, thereby pushing the transmission rod 3100 to move linearly. Through the provision of the first guide slope 2121, when the first guide slope 2121 abuts against the transmission rod 3100, a component force can be generated along the linear movement direction of the transmission rod 3100, facilitating the linear movement of the transmission rod 3100.

[0074] Similarly, the transmission rod 3100 can also be provided with a second guide slope 3120, which is adapted to abut against the protrusion 2120 when the first door 2100 closes part of the washing chamber, so that the transmission rod 3100 can be pushed by the protrusion 2120 to move linearly. With this arrangement, a component force can also be generated along the linear movement direction of the transmission rod 3100, causing the transmission rod 3100 to move linearly.

[0075] Alternatively, the protrusion 2120 may be provided with a first guide slope 2121, and the transmission rod 3100 may be provided with a second guide slope 3120. The contact between the first guide slope 2121 and the second guide slope 3120 causes the transmission rod 3100 to move linearly. Figures 10 to 13 As shown, when the first door 2100 closes part of the washing chamber, the first guide slope 2121 and the second guide slope 3120 located at the bottom of the transmission rod 3100 abut against each other, thus generating a component force on the transmission rod 3100 in the direction from bottom to top. This component force will drive the transmission rod 3100 to move linearly from bottom to top, causing the transmission rod 3100 to push the locking block 3200 to rotate clockwise and engage with the second door latch 2210.

[0076] Combination Figures 1 to 13 As shown, in some embodiments, the drive rod 3100 is adapted to reset when the first door 2100 opens a portion of the washing chamber, and the locking block 3200 is adapted to disengage from the second door latch 2210 to unlock the second door 2200 when the drive rod 3100 resets.

[0077] The first door 2100 can be locked to or unlocked from the main body 1000. Unlocking the first door 2100 from the main body 1000 allows the first door 2100 to open the washing chamber. When the first door 2100 opens part of the washing chamber, the pushing action of the first door 2100 on the transmission rod 3100 disappears, and the transmission rod 3100 resets. The reset of the transmission rod 3100 causes the locking block 3200 and the second door latch 2210 to disengage, thus unlocking the second door 2200. The second door 2200 can then follow the movement of the first door 2100 to open another part of the washing chamber.

[0078] Unlocking the first door 2100 can be achieved by setting the button 2130. The user can operate the button 2130 to cause the button 2130 to disengage the first door latch 2110 and the latch 1230 to unlock the first door 2100. Of course, the first door 2100 can also be unlocked in other ways. Please refer to the relevant technology, which will not be elaborated further.

[0079] The transmission rod 3100 extends vertically and can be reset by gravity. That is, when the first door 2100 pushes the transmission rod 3100 under the action of gravity, the transmission rod 3100 moves against the direction of gravity (rotation or linear movement). When the pushing action of the first door 2100 on the transmission rod 3100 disappears, the transmission rod 3100 can be reset by gravity.

[0080] The transmission rod 3100 can also be reset by the action of elastic force, which is generated by the deformation of an elastic element such as a spring. When the first door 2100 pushes the transmission rod 3100, the transmission rod 3100 moves (rotates or moves linearly), causing the elastic element to generate an elastic force on the first door 2100. This elastic force can make the transmission rod 3100 tend to reset. However, at present, the pushing action of the first door 2100 overcomes the effect of the elastic force. When the pushing action of the first door 2100 on the transmission rod 3100 disappears, the elastic element releases elastic potential energy, and the transmission rod 3100 is reset by the elastic force.

[0081] Similarly, lock block 3200 can also be reset by gravity and / or elastic force.

[0082] See Figures 7 to 13As shown, the locking block 3200 is connected to a tension spring 3300. When the first door 2100 approaches the washing chamber and partially closes the washing chamber, the first door 2100 pushes the transmission rod 3100 to move linearly from bottom to top. The transmission rod 3100 pushes the locking block 3200 to rotate clockwise and engage with the second door latch 2210. When the locking block 3200 rotates clockwise, the tension spring 3300 is stretched. At this time, the tension spring 3300 generates a spring force on the locking block 3200. When the first door 2100 moves away from the washing chamber and partially opens the washing chamber, the first door... When 2100 and the transmission rod 3100 separate, the pushing action on the transmission rod 3100 is canceled. The transmission rod 3100 moves from top to bottom under the action of gravity. At the same time, the elastic force of the tension spring 3300 is applied to the locking block 3200. Under the action of elastic force and gravity, the locking block 3200 rotates counterclockwise to disengage from the second door latch 2210. When the locking block 3200 rotates counterclockwise, it abuts against the top of the transmission rod 3100, which can also generate force on the transmission rod 3100 to move from top to bottom. That is, the transmission rod 3100 is also reset by the action of elastic force.

[0083] Combination Figure 2 and Figure 8 As shown, in some embodiments, the body 1000 includes an inner liner 1100 and a reinforcing frame 1200 disposed on the front side of the inner liner 1100. A transmission rod 3100 and a locking mechanism 3000 are disposed on the reinforcing frame 1200. A washing chamber is formed inside the inner liner 1100. The front side of the inner liner 1100 is open, allowing the first door 2100 and the second door 2200 to cooperate in opening and closing the washing chamber. Therefore, providing a reinforcing frame 1200 on the front side of the inner liner 1100 effectively strengthens the structural strength of the inner liner 1100 and prevents deformation. Furthermore, by distributing the transmission rod 3100 and the locking mechanism 3000 within the reinforcing frame 1200, a supporting foundation is provided for the installation of the transmission rod 3100 and the locking mechanism 3000.

[0084] As described above, the dishwasher also includes a linkage hinge 4000. The first door 2100 and the second door 2200 are connected to the body 1000 via the linkage hinge 4000 to be linked. Based on this, when the first door 2100 and the second door 2200 are linked, the first door 2100 opens the washing chamber before the second door 2200 and closes the washing chamber after the second door 2200.

[0085] In this embodiment, the linkage hinge 4000 ensures that the linkage between the first door 2100 and the second door 2200 is not synchronous, but rather exhibits a lag characteristic. This helps to simplify the cooperation between the locking mechanism 3000 and the second door 2200. The linkage hinge 4000 can be referenced in related technologies.

[0086] When the washing chamber needs to be closed, the second door 2200 follows the first door 2100 to approach the washing chamber. The second door 2200 closes to the position before the first door 2100, and then the first door 2100 closes to the position. The first door 2100 is locked by engaging with the first door latch 2110 and the latch 1230. The first door 2100 pushes the transmission rod 3100 through the first door latch 2110 / protrusion 2120, so that the transmission rod 3100 pushes the locking block 3200 to lock the second door latch 2210. When the washing chamber needs to be opened, the first door 2100 unlocks and moves away from the washing chamber before the second door 2200. As the first door 2100 moves away from the washing chamber, the locking mechanism 3000 (locking block 3200) releases its lock on the second latch 2210. As the first door 2100 continues to move away, the second latch 2210 follows the first door 2100 and begins to move away from the washing chamber. With this configuration, the second latch 2210 and the locking mechanism 3000 (locking block 3200) do not need to cooperate synchronously, which helps to reduce structural complexity.

[0087] The above description is merely a preferred embodiment of this application and does 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.
