[0035] Reference below Figure 1-Figure 5 A washing apparatus 100 according to an embodiment of the present invention is described.

[0036] Reference Figure 1-Figure 5 As shown, the washing device 100 according to the embodiment of the present invention may include: a body 10 , a door assembly 20 and a projection assembly 30 .

[0037] Specifically, the body 10 may have a washing chamber 101 , and the door assembly 20 may open and close a take-in and put-out opening 102 of the washing chamber 101 , so as to facilitate a user to take-in and put-out dishes waiting for washing parts 200 .

[0038] In the related art, the parts of the dishwasher used to place and support tableware (such as bowl baskets) have complex structures. For users, the design layout is unclear. When users place tableware, it is often difficult to directly place the tableware in the corresponding position, resulting in unstable tableware placement or failure to fully utilize the washing space. In some related technologies, the user's ease of use is increased by adding logos, unified structures, or adding movable card rows to parts such as bowl baskets. However, the logos are not clear and difficult to observe, which also affects the appearance of the dishwasher. The unified structure cannot meet the user's placement of a wide variety of non-standard tableware, and the movable card row is cumbersome to operate, and both cannot meet the user's ease of use needs.

[0039] The washing device 100 of the present invention includes a projection assembly 30, such as Figure 1As shown, the projection assembly 30 is configured to project a projection when the door assembly 20 opens the access opening 102, so as to at least prompt the placement position of the items to be washed 200. The user can place the items to be washed 200 according to the prompt of the projection of the projection assembly 30, and place a wide variety of items to be washed 200 to the corresponding positions. The items to be washed 200 are placed firmly, and are not easy to shake or even break during the washing process, and the washing space can be fully and reasonably utilized. In the process of the user placing the items to be washed 200, the projection is clearer and more eye-catching, and the user is easier to observe, and the prompting effect is better. The projection assembly 30 can play a real guiding role, effectively improve the user's ease of use, and be more convenient to use.

[0040] Furthermore, the projection assembly 30 indicates the placement of the items to be washed 200, which has no effect on the structure of the components of the washing device 100 for placing the items to be washed 200, and does not affect normal washing and the appearance. Moreover, during use, the user does not need to adjust the components for placing the items to be washed 200, which is simple and convenient to use.

[0041] Optionally, when the door assembly 20 opens the access opening 102 , the projection assembly 30 can automatically project the projection, or the projection assembly 30 can project the projection according to user instructions.

[0042] Optionally, when the projection assembly 30 projects a projection to indicate the placement of the items 200 to be washed, the projection content may include a loading diagram of the items 200 to be washed, such as pictures, names or sizes of items 200 to be washed of different types and models corresponding to different placement positions. It should be noted that, in some embodiments, the projection of the projection assembly 30 may not only indicate the placement of the items 200 to be washed, but may also indicate appropriate washing time, washing temperature, drying time, drying temperature and other information for the items 200 to be washed, or when the items 200 to be washed are placed at the corresponding positions of the projection area, the washing device 100 may automatically select the corresponding washing mode, etc., so as to make the operation of the washing device 100 easier.

[0043] In addition, it should be noted that, according to actual needs, the projection area of ​​the projection component 30 may include multiple situations. For example, in some embodiments, the projection component 30 may project a projection directly into the washing chamber 101, and the user directly places the items to be washed 200 at the corresponding positions in the washing chamber 101. In other embodiments, the projection component 30 may project a projection to a predetermined area outside the washing chamber 101, and the user places the items to be washed 200 outside the washing chamber 101 and then moves them into the washing chamber 101 for washing.

[0044] According to the washing device 100 of the embodiment of the present invention, the projection component 30 projects a projection to prompt the placement position of the items to be washed 200, and the prompting effect is good, which effectively reduces the time for users to learn to place the items to be washed 200, reduces customer complaints, and makes it easier for users to place the items to be washed 200 to the corresponding positions for washing. The items to be washed 200 are not easily damaged, and the user operation is simpler and more convenient, which effectively solves the pain point of users having difficulty in placing the items to be washed 200, improves the usability of the washing device 100, and improves the user experience.

[0045] According to some embodiments of the present invention, Figure 3 As shown, the washing device 100 may further include a washing basket 40, which may be used to hold the items to be washed 200, so as to support and limit the items to be washed 200 during the washing process to prevent the items to be washed 200 from shaking violently.

[0046] In addition, the washing basket 40 has a washing position and a placing position. When the washing basket 40 is in the washing position, the washing basket 40 is located in the washing chamber 101. When the door assembly 20 opens the placing opening 102, as shown in FIG. Figure 3 As shown, when the washing basket 40 can be moved to the pick-up and placement position, when the washing basket 40 is in the pick-up and placement position, at least a portion of the washing basket 40 can be located within the projection area of ​​the projection assembly 30, as shown in FIG. Figure 4 and Figure 5 As shown, the user can place the items to be washed 200 at the corresponding position in the washing basket 40 according to the projection prompt, and then move the washing basket 40 containing the items to be washed 200 to the washing position for washing, which is more convenient for the user. Optionally, in an embodiment including a washing basket 40, the projection content of the projection component 30 can also include a picture corresponding to the washing basket 40, and the washing basket 40 can overlap or partially overlap with the projected washing basket picture when it is in the placement position.

[0047] Optionally, in the present invention, the washing device 100 may be a pull-down door structure, a pull-up door structure, or a side-opening door structure, all of which are within the scope of protection of the present invention. When the washing device 100 is a pull-up door structure or a side-opening door structure, the projection assembly 30 may project a projection onto a surface such as the ground or a table top in front of the body 10 when the door assembly 20 opens the access opening 102, and the washing basket 40 may be moved above the projection area when it is in the access position.

[0048] In the embodiment of the washing device 100 having a pull-down door structure, Figure 1 and Figure 3 As shown, the lower portion of the door assembly 20 can be rotatably connected to the lower portion of the body 10, and the door assembly 20 can rotate around a rotation axis extending in the horizontal direction to open and close the access port 102. Figure 3As shown, when the door body assembly 20 opens the access opening 102, the projection assembly 30 can project a projection onto the inner surface of the door body assembly 20, that is, onto the side surface of the door body assembly 20 facing the washing chamber 101 when the access opening 102 is closed, and when the washing basket 40 is in the access position, the washing basket 40 can be moved above the inner surface of the door body assembly 20.

[0049] The inner surface of the door assembly 20 serves as a projection wall, which helps to make the projection clearer and easier for users to view. When the washing basket 40 is located above the inner surface of the door assembly 20, the remaining water stains and leftovers in the washing basket 40 can fall onto the inner surface of the door assembly 20 instead of falling directly onto the ground or countertops, which is not easy to pollute the kitchen environment.

[0050] Furthermore, if Figure 3 As shown, when the washing basket 40 is in the access position, the washing basket 40 can be supported on the inner surface of the door assembly 20. No additional support components for the washing basket 40 are required, which is conducive to simplifying the structure of the washing device 100 and reducing production costs. In addition, when the washing basket 40 is supported on the inner surface of the door assembly 20, it can correspond exactly to the projection, for example, it can overlap or partially overlap with the washing basket pattern on the projection diagram, making it easier for the user to move the washing basket 40 to the access position, and it is easier for the washing basket 40 to be aligned with the projection.

[0051] In some embodiments of the present invention, the washing basket 40 may include multiple ones to provide washing of more types and more numbers of items to be washed 200. In some embodiments, the projection assembly 30 may include multiple ones, and multiple projection assemblies 30 may project projections corresponding to multiple washing baskets 40 one by one. In other embodiments, the projection assembly 30 may have multiple projection modes, and multiple projection modes correspond to multiple washing baskets 40 one by one. The projection assembly 30 may project to the corresponding washing basket 40 in each projection mode to prompt the placement of the items to be washed 200 of different washing baskets 40. Multiple projection modes are integrated into one projection assembly 30, which simplifies the structure of the washing device 100, is conducive to simplifying the manufacturing process, and is conducive to reducing costs. Here, "multiple" refers to two or more.

[0052] Furthermore, multiple washing baskets 40 can be arranged up and down, and the projection direction of the projection assembly 30 in multiple projection modes remains unchanged. In the process of placing the items to be washed 200, there is no need to frequently adjust the projection, and the operation is simpler. In addition, the projection area of ​​the projection assembly 30 is fixed, and the placement positions of the multiple washing baskets 40 are also fixed. It is easier to align each washing basket 40 with the projection in the corresponding projection mode, and the visual effect is better, which is conducive to improving the prompt effect of the projection assembly 30 on the user, and it is also easier for the user to move the washing basket 40.

[0053] In some embodiments, when the user places the items 200 to be washed, multiple washing baskets 40 are arranged up and down at the placement position, and the projection assembly 30 is first in the projection mode corresponding to the washing baskets 40 on the lower layer. After the washing baskets 40 on the lower layer are placed, the projection assembly 30 switches to the projection mode of the washing baskets 40 on the upper layer. After the washing baskets 40 on this layer are placed, the projection assembly 30 continues to switch the projection mode until the placement is complete. Therefore, in the process of the projection assembly 30 switching different projection modes, the projection direction of the projection assembly 30 remains unchanged, the washing baskets 40 do not need to be moved multiple times, and the projection does not need to be adjusted frequently, the user operation is simpler, and the items 200 to be washed are not easily damaged due to frequent movement.

[0054] In other embodiments, the user can move only one layer of the washing basket 40 to the placement position at a time, and the projection assembly 30 is in the projection mode corresponding to the washing basket 40, so that the projection is clearer and easier for the user to watch the projection. In addition, when the projection assembly 30 switches between different projection modes, the projection direction of the projection assembly 30 remains unchanged, and there is no need to frequently adjust the projection. The placement position of each washing basket 40 is fixed, and it is easier to align the washing basket 40 with the projection.

[0055] It should be noted that, in the present invention, the installation position of the projection assembly 30 can be adjusted according to actual needs. Optionally, the projection assembly 30 can be installed on the body 10 or the door assembly 20, so that when the washing device 100 moves, the projection assembly 30, the body 10 and the door assembly 20 move together, and the projection assembly 30 can be installed and adjusted at the factory for projection angle, etc., and the user does not need to debug after purchase. Of course, optionally, the projection assembly 30 can also be installed on a wall, the ground, a bracket, etc.

[0056] Further, in an embodiment where the projection assembly 30 is mounted on the body 10, Figure 1 and Figure 2 As shown, the projection assembly 30 can be installed on the top of the main body 10, and the projection assembly 30 is arranged adjacent to the upper edge of the main body 10, that is, the projection assembly 30 is installed on the top of the main body 10 and in a front position, so that the projection assembly 30 can project a projection onto the area located in front of the main body 10, which is convenient for projection, and it is also more convenient for users to take and place the items to be washed 200, and the structural design of the washing device 100 is more reasonable.

[0057] According to some embodiments of the present invention, Figure 1As shown, the washing device 100 may further include a door lock assembly 50, and the door lock assembly 50 may include a locking portion 51 and a locking matching portion 52. One of the locking portion 51 and the locking matching portion 52 may be provided at the door assembly 20, and the other of the locking portion 51 and the locking matching portion 52 may be provided at the body 10. Thus, when the door assembly 20 closes the access opening 102, the locking portion 51 may be locked with the locking matching portion 52 to prevent the door assembly 20 from opening during the washing process of the washing device 100 washing the items to be washed 200.

[0058] In addition, if Figure 2 As shown, the projection assembly 30 can be disposed adjacent to the locking mating portion 52 to make the structure more compact.

[0059] Further, at least one of the locking and matching portion 52 and the projection assembly 30 may be disposed in the middle of the upper edge of the body 10.

[0060] In some embodiments of the present invention, Figure 2 As shown, the locking mating portion 52 may include a locking hole 521, and the locking portion 51 may be inserted into the locking hole 521 to achieve connection with the locking mating portion 52. The projection assembly 30 may include a projection hole 301, and the projection assembly 30 may project a projection through the projection hole 301. The projection hole 301 and the locking hole 521 may be integrated into the same hole to simplify the structure of the door body 10 and save space.

[0061] According to some embodiments of the present invention, Figure 1 As shown, the body 10 may include: an inner liner 11 and a reinforcement frame 12. The inner liner 11 may have a washing chamber 101, and the reinforcement frame 12 may be connected to the opening edge of the washing chamber 101 to define a take-in and put-out port 102. The reinforcement frame 12 may strengthen the structure of the inner liner 11, so that the inner liner 11 is not easily deformed, and the structure is more solid and stable. At least one of the locking and fitting part 52 and the projection assembly 30 may be installed on the reinforcement frame 12, and the locking and fitting part 52 and the projection assembly 30 are easy to install, reduce the structural impact on the inner liner 11, and are conducive to improving the sealing of the washing chamber 101.

[0062] Furthermore, if Figure 2As shown, the reinforcement frame 12 may include: a square frame body 121, a front side plate 122 and a rear side plate 123. The frame body 121 may be connected to the inner liner 11 to strengthen the structure of the inner liner 11 from the circumferential direction of the inner liner 11. The front side plate 122 may be connected to the front side edge of the frame body 121, and the front side plate 122 may extend in a direction away from the access port 102. The rear side plate 123 may be connected to the rear side edge of the frame body 121, and the rear side plate 123 may extend in a direction away from the access port 102. Thus, the front side plate 122 and the rear side plate 123 may strengthen the structure of the frame body 121 to further strengthen the structural stability of the body 10, and the front side plate 122 makes the appearance of the body 10 more neat and beautiful.

[0063] like Figure 2 As shown, the front side plate 122 may be provided with a projection hole 301 for the projection assembly 30 to project a projection, and the projection assembly 30 may be located between the front side plate 122 and the rear side plate 123, so that the structure is more compact, and the front side plate 122 and the rear side plate 123 may protect the structure of the projection assembly 30. Optionally, at least one of the upper frame beam of the frame body 121, the front side plate 122, and the rear side plate 123 may be connected to the projection assembly 30 to achieve the fixation of the projection assembly 30.

[0064] It should be noted that in an embodiment where the main body 10 does not include the reinforcement frame 12, the opening of the washing chamber 101 can be formed as a take-in and put-out port 102, and the projection assembly 30 can be installed in the inner tank 11, for example, the projection assembly 30 can be installed in the middle and front position of the top of the inner tank 11.
