Description

Technical Field

[0001] This application relates to the field of dishwashing technology, specifically to an automatic placement device, a washing machine, and a smart kitchen. Background Technology

[0002] As people's living standards continue to improve, cleaning machines such as dishwashers are increasingly entering households as a type of kitchen appliance. Current dishwashers typically use a dish rack to hold the dishes and use spray arms to spray water jets to clean them.

[0003] However, when using the dish racks in these dishwashers, users need to place the dishes one by one in the racks before washing. In particular, in order to improve the washing effect, users need to arrange dishes such as plates or bowls in a specific direction. This not only requires users to know the placement direction in advance, but also makes it very difficult to place them one by one. It requires users to bend over for a long time to place them, which is both time-consuming and laborious.

[0004] To achieve automatic separation and placement of tableware, some existing dishwashers often require complex active drive mechanisms (such as lead screws and motor rotor assemblies) inside the dish rack. This results in a complex internal structure, numerous parts, high costs, and limited transmission stability. For example, while these dishwasher solutions simplify the placement process to some extent, their separation action relies on a lead screw drive mechanism located in the dish rack body to separate the clamps. The entire mechanism is integrated inside the dish rack, making the structure cumbersome. Summary of the Invention

[0005] To address the issue that existing dishwashers require complex active drive mechanisms, resulting in complex internal structures, numerous parts, high costs, and limited transmission stability, this application provides an automatic placement device, a washing machine, and a smart kitchen. This device links the state switching of the separation mechanism with the pushing and pulling motion of the movable frame, eliminating the need for additional complex active drive mechanisms. It can automatically place multiple stacked dishes, avoiding the need for users to bend over for extended periods, thus achieving a time-saving and labor-saving effect.

[0006] According to one aspect of this application, one embodiment provides an automatic placement device for use in the housing and movable frame of a washing machine, comprising: a limiting guide mechanism for being fixed to the movable frame; a separation mechanism slidably disposed on the limiting guide mechanism and having a stacked state and an unfolded state that can be switched between each other, for carrying multiple tableware; and a linkage mechanism for being disposed between the housing and the movable frame; wherein the linkage mechanism is drivenly connected to the separation mechanism and is configured to output a driving force based on the movement of the movable frame relative to the housing, so as to drive the separation mechanism to switch from the unfolded state to the stacked state during the process of the movable frame being pulled out of the housing; and to drive the separation mechanism to switch from the stacked state to the unfolded state during the process of the movable frame being pushed into the housing.

[0007] This design, because the linkage mechanism is constructed to output driving force based on the movement of the movable frame relative to the box, allows the state switching of the separation mechanism and the movement of the movable frame relative to the box to be linked through the linkage mechanism. Therefore, when placing multiple pieces of tableware onto the movable frame, the washing machine of this application only needs to pull the movable frame out and then push it in to automatically place multiple pieces of tableware, eliminating the need for the user to bend over multiple times. Furthermore, when retrieving multiple pieces of tableware, the washing machine of this application only needs to pull out the movable frame to automatically stack multiple pieces of tableware, eliminating the need for the user to bend over multiple times. In other words, the automatic placement device of this application links the state switching of the separation mechanism with the pushing and pulling movement of the movable frame relative to the box through the linkage mechanism. Without the need for an additional complex active drive mechanism, it can automatically place multiple stacked pieces of tableware, simplifying the overall structure, reducing costs, improving the stability of state switching, and avoiding prolonged bending over for placement, achieving a time-saving and labor-saving technical effect.

[0008] In one embodiment of this application, the limiting and guiding mechanism has a first guide rail extending laterally, a second guide rail located at one end of the first guide rail and extending vertically, and a limiting point located between the first guide rail and the second guide rail; the separating mechanism includes a base slidably disposed on the first guide rail for stacking multiple pieces of the tableware, a top frame slidably disposed on the second guide rail and unidirectionally limited by the limiting point, and multiple separating frames sequentially and separably stacked between the base and the top frame.

[0009] This configuration is because the second guide rail is located at one end of the first guide rail and extends vertically. Therefore, when the separation mechanism switches from the unfolded state to the stacked state under the drive of the linkage mechanism, the top frame and multiple separation frames move upward along the second guide rail under the push of the base, so as to automatically stack on the base under their own weight, so that multiple tableware also automatically stack on the base under their own weight.

[0010] In one embodiment of this application, when the separation mechanism is in a stacked state, the top frame and a plurality of the separation frames are vertically stacked above the base along the second guide rail; when the separation mechanism is in an unfolded state, the top frame is positioned between the first guide rail and the second guide rail by the limiting point, and a plurality of the separation frames are arranged laterally at intervals along the first guide rail on the side of the base.

[0011] With this design, when multiple pieces of tableware need to be placed on the movable rack, simply pull the movable rack out from the housing to switch the separation mechanism to a stacking state, allowing multiple pieces of tableware to be placed on the base of the separation mechanism all at once. Then, pushing the movable rack back into the housing switches the separation mechanism to an unfolded state, allowing the multiple separators within the mechanism to separate and horizontally disperse the stacked tableware, eliminating the need for the user to bend over for extended periods. When multiple pieces of tableware need to be removed from the movable rack, simply pull the movable rack out from the housing to switch the separation mechanism to a stacking state, allowing the multiple separators within the mechanism to overlap and vertically stack the horizontally dispersed tableware on the base, facilitating the removal of multiple pieces of tableware at once and reducing the time spent bending over to retrieve them.

[0012] In one embodiment of this application, the linkage mechanism pulls the base bidirectionally, and is used to pull the base along the first guide rail and move it closer to the second guide rail when the movable frame is pulled out of the box, so that the separation mechanism switches to the stacked state; and when the movable frame is pushed into the box, the base is pulled along the first guide rail and move away from the second guide rail, so that the separation mechanism switches to the unfolded state.

[0013] With this configuration, the linkage mechanism of this application can reliably convert the pushing and pulling motion of the movable frame relative to the box into a bidirectional driving force applied to the base, so as to ensure that the separation mechanism can switch states accordingly with the pushing and pulling motion of the movable frame.

[0014] In one embodiment of this application, the first guide rail extends in the front-back direction; the second guide rail extends upward from the front end of the first guide rail.

[0015] With this configuration, when the movable frame is pulled forward out of the box, the linkage mechanism pulls the base forward to move it closer to the second guide rail along the first guide rail. This causes the top frame and multiple separate racks to move upward along the second guide rail under the push of the base. At this time, the top frame and multiple separate racks gradually stack on top of the base under their own weight, allowing the separation mechanism to switch from an unfolded state to a stacked state, facilitating the placement of multiple pieces of tableware on the base. When the movable frame is pushed backward into the box, the linkage mechanism pulls the base backward to move it away from the second guide rail along the first guide rail. This causes the top frame and multiple separate racks to first move downward along the second guide rail under their own weight, and then move backward along the first guide rail under the pull of the base. At this time, the top frame is stopped by the limiting point of the limiting guide mechanism, and the multiple separate racks are arranged at intervals along the first guide rail under the pull of the base, allowing the separation mechanism to switch from a stacked state to an unfolded state, facilitating the horizontal dispersal of multiple pieces of tableware.

[0016] In one embodiment of this application, the second guide rail extends obliquely forward and upward from the front end of the first guide rail.

[0017] This design makes it convenient for users to place multiple stacked pieces of tableware onto the base, while also ensuring that the multiple pieces of tableware stacked on the base can be placed against the multiple separation racks under their own weight.

[0018] In one embodiment of this application, the limiting guide mechanism includes a guide rod and a limiting rod; the rear portion of the guide rod extends straight backward to form the first guide rail, and the front portion of the guide rod extends obliquely upward to form the second guide rail; the limiting rod extends obliquely downward from the front end of the guide rod to form the limiting point.

[0019] With this configuration, the limiting rod of this application can prevent the top frame from disengaging from the second guide rail, ensuring that the top frame can always move along the second guide rail.

[0020] In one embodiment of this application, the limiting guide mechanism has two guide rods and two limiting rods, which are arranged parallel to each other on the left and right sides of the separation mechanism.

[0021] This configuration is intended to more stably guide the separation mechanism during state switching.

[0022] In one embodiment of this application, the limiting and guiding mechanism further includes a first support rod and a second support rod; the two ends of the first support rod are fixedly connected to the rear of the two guide rods, so as to be located at the rear end of the first guide rail; the two ends of the second support rod are fixedly connected to the front of the two guide rods, so as to be located at the front end of the first guide rail.

[0023] With this configuration, the first support rod and the second support rod can stably support the two guide rods from both ends, thereby improving the overall structural stability of the limiting and guiding mechanism. They can also guide the linkage mechanism forward and backward, enabling the linkage mechanism to pull the base in both directions to move back and forth along the first guide rail.

[0024] In one embodiment of this application, the linkage mechanism includes a first pulling member and a second pulling member; one end of the first pulling member is fixedly connected to the housing, and the other end of the first pulling member bypasses the rear end of the first guide rail to be fixedly connected forward to the base; one end of the second pulling member is fixedly connected to the housing, and the other end of the second pulling member bypasses the front end of the first guide rail to be fixedly connected backward to the base.

[0025] With this configuration, the linkage mechanism of this application can pull the base bidirectionally through the first and second pulling members, so that the base moves forward along the first guide rail when the movable frame is pulled out, and moves backward along the first guide rail when the movable frame is pushed in, thereby realizing that the separation mechanism automatically switches states as the movable frame is pushed and pulled.

[0026] In one embodiment of this application, the first traction member extends forward around the first support rod; the second traction member extends backward around the second support rod.

[0027] With this configuration, when the movable frame is pulled forward relative to the box, the second support rod moves forward away from the opening of the box under the action of the movable frame. This causes the second pulling member, which bypasses the second support rod, to pull the base forward along the first guide rail towards the second support rod, thus switching the separation mechanism from the unfolded state to the stacked state. Conversely, when the movable frame is pushed backward relative to the box, the first support rod moves backward away from the opening of the box under the action of the movable frame. This causes the first pulling member, which bypasses the first support rod, to pull the base backward along the first guide rail towards the first support rod, thus switching the separation mechanism from the stacked state to the unfolded state.

[0028] In one embodiment of this application, the limiting and guiding mechanism further includes a first pulley and a second pulley; the first pulley is rotatably disposed on the first support rod and is passed around by the first pulling member; the second pulley is rotatably disposed on the second support rod and is passed around by the second pulling member.

[0029] With this configuration, the first pulley of this application can reduce the frictional force between the first pulling member and the first support rod; the second pulley of this application can reduce the frictional force between the second pulling member and the second support rod.

[0030] In one embodiment of this application, the base includes a support frame slidably attached to the first guide rail and a first guide post fixedly connected to the support frame and arranged perpendicular to the support frame; a plurality of separation frames are slidably fitted onto the first guide post; the top frame includes a limiting frame slidably attached to the second guide rail and a second guide post fixedly connected to the limiting frame and arranged perpendicular to the limiting frame; a plurality of separation frames are slidably fitted onto the second guide post.

[0031] With this configuration, the first guide post and the second guide rail of this application can respectively guide multiple separation frames to move along a direction perpendicular to the support frame and the limiting frame, so that the support frame moves along the first guide rail, or the limiting frame moves along the second guide rail.

[0032] In one embodiment of this application, the first guide post and the second guide post are parallel to each other.

[0033] This arrangement, with staggered placement on each separation frame, ensures that multiple separation frames are always arranged in a direction perpendicular to the support frame and the limiting frame, and also prevents structural interference between the first guide post and the second guide post when they are stacked.

[0034] In one embodiment of this application, the base further includes a first roller rotatably disposed on the support frame and rollingly overlapping with the first guide rail; the top frame further includes a second roller rotatably disposed on the limiting frame and rollingly overlapping with the second guide rail.

[0035] With this configuration, the roller mentioned in this application can roll on the guide rail, which helps to reduce the friction between the two and prevents it from derailing.

[0036] In one embodiment of this application, each of the separation frames includes a connecting beam and a pair of separating arms that bend in the same direction from opposite ends of the connecting beam; each separating arm is slidably fitted onto a corresponding first guide post and second guide post.

[0037] In one embodiment of this application, the separation mechanism further includes a spacing constraint member, which is sequentially connected to the base, the plurality of separation frames, and the top frame.

[0038] This design allows multiple separation frames to be pulled apart during deployment while simultaneously constraining the maximum distance between adjacent separation frames.

[0039] In one embodiment of this application, the spacing constraint is a flexible element.

[0040] This design allows the frames to be stretched taut during unfolding to separate them from each other, while also constraining the maximum distance between adjacent frames. It also allows the frames to bend during stacking to prevent them from being blocked from being stacked together.

[0041] In one embodiment of this application, the flexible member maintains the same length between any two adjacent separation frames.

[0042] This design ensures that the spacing between any two adjacent dividers remains consistent, guaranteeing that multiple pieces of tableware can be evenly distributed laterally.

[0043] According to another aspect of this application, one embodiment of this application further provides a cleaning machine, comprising: a housing; a door movably disposed in the housing for opening the opening of the housing when the door is opened and closing the opening of the housing when the door is closed; a movable frame slidably disposed in the housing for pulling out the housing when the door is opened and pushing into the housing when the door is closed; and an automatic placement device as described above, disposed in the housing and the movable frame.

[0044] With this configuration, the washing machine of this application can automatically stack multiple pieces of tableware when the movable frame is pulled out of the box, and automatically unfold multiple pieces of tableware when the movable frame is pushed into the box, avoiding the user having to bend over for a long time to place them, thus achieving the technical effect of saving time and effort.

[0045] According to another aspect of this application, one embodiment of this application further provides a smart kitchen, including: the aforementioned cleaning machine; and a robot, which cooperates with the cleaning machine to push and pull the movable frame in the cleaning machine and to pick up and place multiple stacked tablewares onto the base of the automatic placement device in the cleaning machine.

[0046] With this configuration, the robot in the smart kitchen of this application only needs to push or pull the movable frame relative to the box to automatically arrange and place the tableware; this not only greatly reduces the burden of manual operation, but also effectively reduces the hardware configuration and algorithm control requirements of the robot in terms of visual recognition and precise positioning, reduces the overall R&D and production costs, and improves the stability and versatility of the equipment operation.

[0055] Considering that most dishwashers require users to place dishes one by one in the dish racks before washing, this necessitates prolonged bending over, which is both time-consuming and laborious. While some dishwashers utilize mechanical arrays of dish racks for automatic dish placement, these actions rely on active drive mechanisms within the racks, resulting in complex structures and high costs. To address these issues, this application provides an automatic dish placement device, a washing machine, and a smart kitchen. This device links the switching of a separation mechanism with the pushing and pulling motion of the movable frame, eliminating the need for complex active drive mechanisms. It automatically places multiple stacked dishes, saving users time and effort by avoiding prolonged bending over.

[0056] Specifically, such as Figure 1 and Figure 2 As shown, one embodiment of this application provides a washing machine, which may include an automatic placement device 1, a housing 2, a door 3, and a movable frame 4. The door 3 is movably disposed on the housing 2, used to open the opening of the housing 2 when the door is opened and to close the opening of the housing 2 when the door is closed. The movable frame 4 is movably disposed on the housing 2, used to pull out the housing 2 when the door is opened and to push in the housing 2 when the door is closed. The automatic placement device 1 is disposed on the housing 2 and the movable frame 4, used to automatically stack multiple pieces of tableware W when the movable frame 4 is pulled out of the housing 2, and to automatically unfold multiple pieces of tableware W when the movable frame 4 is pushed in the housing 2. It is understood that the washing machine mentioned in this application may be implemented as, but is not limited to, household appliances such as dishwashers or disinfection cabinets; furthermore, in addition to the above-mentioned components, the washing machine mentioned in this application may also include, but is not limited to, functional entities capable of performing functions such as cleaning or disinfection, which will not be elaborated upon further in this application. Furthermore, the movable frame mentioned in this application may be implemented as a bowl rack, basket, or tray, etc.; the tableware W mentioned in this application may be implemented as bowls, plates, and / or dinner plates, etc.

[0057] More specifically, such as Figures 1 to 9As shown, the automatic placement device 1 may include a limiting guide mechanism 10, a separation mechanism 20, and a linkage mechanism 30 for fixing to the movable frame 4. The separation mechanism 20 is slidably disposed on the limiting guide mechanism 10 and has a stacked state and an unfolded state that can be switched between each other, for carrying multiple pieces of tableware W. The linkage mechanism 30 is disposed between the box 2 and the movable frame 4; wherein the linkage mechanism 30 is drivenly connected to the separation mechanism 20 and is configured to output a driving force based on the movement of the movable frame 4 relative to the box 2, so as to drive the separation mechanism 20 to switch from the unfolded state to the stacked state when the movable frame 4 is pulled out of the box 2; and to drive the separation mechanism 20 to switch from the stacked state to the unfolded state when the movable frame 4 is pushed into the box 2.

[0058] It is worth noting that because the linkage mechanism 30 is configured to output driving force based on the movement of the movable frame 4 relative to the box 2, the state switching of the separation mechanism 20 and the movement of the movable frame 4 relative to the box 2 can be linked through the linkage mechanism 30. Therefore, when placing multiple tableware Ws onto the movable frame 4, the washing machine of this application only needs to pull out the movable frame 4 and then push it in to achieve automatic placement of multiple tableware Ws without requiring the user to bend over multiple times. In other words, during the entire placement process, the user only needs to bend over when the movable frame 4 is pulled out and place the stacked tableware Ws onto the base 21 at once, which saves both time and effort.

[0059] Furthermore, when the cleaning machine of this application takes out multiple pieces of tableware W, it only needs to pull out the movable frame 4 to automatically stack the multiple pieces of tableware W without the user having to bend over to take them out multiple times. In other words, during the entire taking process, the user only needs to bend over when the movable frame 4 is pulled out to take out the multiple pieces of tableware W stacked on the base 21 at once, which saves both time and effort.

[0060] In other words, the automatic placement device 1 of this application links the state switching of the separation mechanism 20 with the pushing and pulling motion of the movable frame 4 relative to the box 2 through the linkage mechanism 30. Without the need for additional complex active drive mechanisms, it can automatically place multiple stacked tableware W, which simplifies the overall structure, reduces costs, improves the stability of state switching, and avoids users bending over for a long time to place the tableware, thus achieving the technical effect of saving time and effort.

[0061] For example, the limiting and guiding mechanism 10 may have a first guide rail 101 extending laterally, a second guide rail 102 located at one end of the first guide rail 101 and extending vertically, and a limiting point 103 located between the first guide rail 101 and the second guide rail 102. The separating mechanism 20 includes a base 21 slidably disposed on the first guide rail 101 for stacking multiple pieces of tableware W, a top frame 22 slidably disposed on the second guide rail 102 and unidirectionally limited by the limiting point 103, and multiple separating frames 23 sequentially and separably stacked between the base 21 and the top frame 22.

[0062] It is worth noting that because the second guide rail 102 is located at one end of the first guide rail 101 and extends vertically, when the separation mechanism 20 switches from the unfolded state to the stacked state under the drive of the linkage mechanism 30, the top frame 22 and multiple separation frames 23 move upward along the second guide rail 102 under the push of the base 21, so as to automatically stack on top of the base 21 under their own gravity, so that multiple pieces of tableware W also automatically stack on top of the base 21 under their own gravity. It is understood that the guide rail mentioned in this application can be a solid guide rail provided by a guide rod or guide groove, or a virtual guide rail provided by a rotary hinge, as long as it can guide the separation mechanism 20 to switch states, which will not be elaborated further in this application.

[0063] Optionally, such as Figure 1 , Figure 3 , Figure 4 as well as Figure 8 As shown, when the separating mechanism 20 is in a stacked state, the top rack 22 and multiple separating racks 23 are vertically stacked above the base 21 along the second guide rail 102, so that multiple pieces of tableware W can be vertically stacked on the base 21 and respectively correspond to multiple separating racks 23, so as to take and put multiple stacked pieces of tableware W at one time, which helps to shorten the time the user spends bending over to take and put them down. Figure 2 , Figure 5 , Figure 6 as well as Figure 9 As shown, when the separation mechanism 20 is in the unfolded state, the top frame 22 is limited by the limiting point 103 between the first guide rail 101 and the second guide rail 102. Multiple separation frames 23 are arranged laterally along the first guide rail 101 at intervals on the side of the base 21, so that multiple tableware W are separated by the corresponding separation frame 23 to be laterally dispersed, which facilitates the automatic unfolding of multiple stacked tableware W to the target position (such as a washable and / or disinfectable position), prevents multiple tableware W from blocking each other, and facilitates washing and / or disinfection.

[0064] Thus, as Figure 1 , Figure 2 , Figure 8 as well as Figure 9As shown, when multiple pieces of tableware W need to be placed on the movable frame 4, simply pull the movable frame 4 out from the box 2 to switch the separation mechanism 20 to a stacking state, so that multiple stacked pieces of tableware W can be placed on the base 21 of the separation mechanism 20 at once; then push the movable frame 4 back into the box 2 to switch the separation mechanism 20 to an unfolded state, so that the multiple separation racks 23 in the separation mechanism 20 separate from each other to disperse the stacked pieces of tableware W laterally, without requiring the user to bend over for a long time to place them. It is understood that the multiple pieces of tableware W mentioned in this application can be stacked together on the base 21 with the opening facing upwards or downwards; at this time, the center lines of the multiple pieces of tableware W basically coincide.

[0065] Similarly, such as Figure 1 and Figure 8 As shown, when multiple pieces of tableware W need to be taken out from the movable frame 4, simply pull the movable frame 4 out from the box 2 to switch the separation mechanism 20 to the stacking state, so that the multiple separation racks 23 in the separation mechanism 20 are stacked on top of each other to vertically stack the horizontally dispersed pieces of tableware W on the base 21, which makes it easy to take out the stacked pieces of tableware W at one time, and also helps to shorten the time for users to bend over to pick them up.

[0066] It should be noted that the washing machine of this application only needs to set the limiting guide mechanism 10 and the linkage mechanism 30 of the automatic placement device 1 on the original bowl rack and box respectively, so that it can be linked with the pushing and pulling movement of the movable frame 4. This allows multiple separation racks 23 to be able to spread out horizontally with multiple tableware W when pushed into the movable frame 4, and to be able to stack multiple tableware W vertically together with multiple tableware W when pulled out of the movable frame 4, without the need to set up other drive mechanisms. This simplifies the overall structure and makes it easy to modify existing washing machines into washing machines with automatic placement function without replacing them with new washing machines, thus reducing costs.

[0067] Optionally, the linkage mechanism 30 pulls the base 21 in both directions. When the movable frame 4 is pulled out of the housing 2, it pulls the base 21 along the first guide rail 101 towards the second guide rail 102, so that the separation mechanism 20 switches to a stacked state. When the movable frame 4 is pushed into the housing 2, it pulls the base 21 along the first guide rail 101 away from the second guide rail 102, so that the separation mechanism 20 switches to an unfolded state. In this way, the linkage mechanism 30 of this application can reliably convert the pushing and pulling motion of the movable frame 4 relative to the housing 2 into a bidirectional driving force applied to the base 21, so as to ensure that the separation mechanism 20 can switch states accordingly with the pushing and pulling motion of the movable frame 4.

[0068] For ease of understanding, this application uses the normal placement of the cleaning machine as a reference, defining the side closer to the ground as the lower side and the side farther from the ground as the upper side; the side facing the user is defined as the front side, and the side away from the user is defined as the rear side. It is understood that the lateral extension mentioned in this application can refer to extension along a horizontal direction or in a direction inclined relative to a horizontal plane; the vertical extension mentioned in this application can refer to extension along a vertical direction or in a direction inclined relative to a vertical plane.

[0069] For example, such as Figure 1 and Figure 2 As shown, the limiting guide mechanism 10 can be fixed to the movable frame 4 along the front-to-back direction, so that the first guide rail 101 and the second guide rail 102 in the limiting guide mechanism 10 are arranged along the pushing and pulling direction of the movable frame 4, which facilitates the linkage between the state switching of the separation mechanism 20 and the pushing and pulling movement of the movable frame 4. It is understood that in other examples of this application, the limiting guide mechanism 10 can be fixed to the movable frame 4 along the left-to-right direction. In this case, although the first guide rail 101 and the second guide rail 102 in the limiting guide mechanism 10 are arranged along the pushing and pulling direction perpendicular to the movable frame 4, they can still be linked with the pushing and pulling movement of the movable frame 4 through the arrangement of the linkage mechanism 30.

[0070] Optionally, such as Figures 3 to 9 As shown, the first guide rail 101 extends in the front-rear direction; the second guide rail 102 extends upward from the front end of the first guide rail 101. Thus, as... Figure 1 and Figure 8 As shown, when the movable frame 4 is pulled forward out of the box 2, the linkage mechanism 30 pulls the base 21 forward to move it closer to the second guide rail 102 along the first guide rail 101, causing the top frame 22 and multiple separate racks 23 to move upward along the second guide rail 102 under the push of the base 21; at this time, the top frame 22 and multiple separate racks 23 gradually stack on top of the base 21 under their own weight, causing the separation mechanism 20 to switch from the unfolded state to the stacked state, making it convenient to stack multiple tableware W on the base 21. Figure 2 and Figure 9As shown, when the movable frame 4 is pushed backward into the box 2, the linkage mechanism 30 pulls the base 21 backward to move away from the second guide rail 102 along the first guide rail 101. This causes the top frame 22 and multiple separation frames 23 to move downward along the second guide rail 102 under their own weight, and then move backward along the first guide rail 101 under the pull of the base 21. At this time, the top frame 22 is restricted by the limiting point 103 of the limiting guide mechanism 10 to stop moving, and the multiple separation frames 23 are arranged at intervals along the first guide rail 101 under the pull of the base 21, so that the separation mechanism 20 switches from the stacked state to the unfolded state, which makes it easier to disperse multiple tableware W laterally.

[0071] Optionally, such as Figures 7 to 9 As shown, the second guide rail 102 is arranged at an angle relative to the first guide rail 101, and the angle between the second guide rail 102 and the first guide rail 101 is greater than 90°; that is, the second guide rail 102 extends at an angle from the front end of the first guide rail 101 towards the front and upward, which not only makes it convenient for users to pick up and put multiple stacked tableware Ws onto the base 21, but also ensures that the multiple tableware Ws stacked on the base 21 can correspondingly abut against the multiple separation racks 23 under their own weight.

[0072] Optionally, such as Figures 3 to 7 As shown, the limiting and guiding mechanism 10 includes a guide rod 11 and a limiting rod 12. The rear portion of the guide rod 11 extends straight backward to form the first guide rail 101, and the front portion of the guide rod 11 extends obliquely upward to form the second guide rail 102. The limiting rod 12 extends obliquely downward from the front end of the guide rod 11 to form the limiting position 103, which is used to restrict the top frame 22 from disengaging from the second guide rail 102, ensuring that the top frame 22 can always move along the second guide rail 102. It is understood that in other examples of this application, the limiting position 103 may also be provided by a positioning block or magnetic adsorption, which will not be described in detail here.

[0073] Optionally, such as Figure 3 , Figure 5 as well as Figure 7 As shown, the guide rod 11 is integrally connected to the limiting rod 12 so that it can be formed by bending a single rod, which helps to reduce processing costs.

[0074] Optionally, such as Figure 3 , Figure 5 as well as Figure 7 As shown, the limiting guide mechanism 10 has two guide rods 11 and two limiting rods 12, which are arranged parallel to each other on the left and right sides of the separation mechanism 20, so as to more stably guide the separation mechanism 20 to switch states.

[0075] Optionally, such as Figure 3 , Figure 5 as well as Figure 7 As shown, the limiting and guiding mechanism 10 also includes a first support rod 13 and a second support rod 14. The two ends of the first support rod 13 are fixedly connected to the rear of the two guide rods 11, located at the rear end of the first guide rail 101. The two ends of the second support rod 14 are fixedly connected to the front of the two guide rods 11, located at the front end of the first guide rail 101. Thus, the first support rod 13 and the second support rod 14 can stably support the two guide rods 11 from both ends, improving the overall structural stability of the limiting and guiding mechanism 10, and also provide forward and backward guidance for the linkage mechanism 30, enabling the linkage mechanism 30 to pull the base 21 bidirectionally to move back and forth along the first guide rail 101. It is understood that the limiting and guiding mechanism 10 of this application can be, but is not limited to, fixedly connected to the movable frame 4 via the first support rod 13 and the second support rod 14.

[0076] It is worth noting that, in this example of the application, such as Figure 3 , Figure 5 as well as Figure 7 As shown, the two ends of the first support rod 13 can be integrally connected to the rear ends of the two guide rods 11, so that the two guide rods 11, the two limiting rods 12, and the first support rod 13 can be formed by bending a single rod. In addition, the second support rod 14 can be welded to, but is not limited to, the front bend of the guide rod 11, so as to be located between the first guide rail 101 and the second guide rail 102.

[0077] According to the above embodiments of this application, as Figure 3 , Figure 5 , Figure 8 as well as Figure 9 As shown, the linkage mechanism 30 may include a first pulling member 31 and a second pulling member 32; one end of the first pulling member 31 is fixedly connected to the housing 2, and the other end of the first pulling member 31 passes around the rear end of the first guide rail 101 to be fixedly connected forward to the base 21; one end of the second pulling member 32 is fixedly connected to the housing 2, and the other end of the second pulling member 32 passes around the front end of the first guide rail 101 to be fixedly connected backward to the base 21, so that the base 21 is pulled bidirectionally by the first pulling member 31 and the second pulling member 32, so that the base 21 moves forward along the first guide rail 101 when the movable frame 4 is pulled out, and moves backward along the first guide rail 101 when the movable frame 4 is pushed in, thereby realizing that the separation mechanism 20 automatically switches states as the movable frame 4 is pushed and pulled.

[0078] It is worth noting that in other examples of this application, the linkage mechanism 30 can also be implemented as a push-pull rod or a connecting rod. As long as the base 21 and the housing 2 are connected simultaneously, the push-pull motion of the movable frame 4 relative to the housing 2 can still be converted into a bidirectional driving force applied to the base 21. Alternatively, the linkage mechanism 30 can also be implemented as a gear and rack assembly or a magnetic coupling assembly, as long as the push-pull motion of the movable frame 4 relative to the housing 2 can be converted into a bidirectional driving force applied to the base 21. This application will not elaborate further on this.

[0079] Optionally, such as Figure 8 and Figure 9 As shown, the first pulling member 31 extends forward around the first support rod 13, such that both ends of the first pulling member 31 are respectively connected forward to the box body 2 and the base 21; the second pulling member 32 extends backward around the second support rod 14, such that both ends of the second pulling member 32 are respectively connected backward to the box body 2 and the base 21. Thus, when the movable frame 4 is pulled forward relative to the housing 2, the second support rod 14 moves forward away from the opening of the housing 2 under the action of the movable frame 4, causing the second pulling member 32, which bypasses the second support rod 14, to pull the base 21 forward along the first guide rail 101 to approach the second support rod 14, thereby switching the separation mechanism 20 from the unfolded state to the stacked state; and when the movable frame 4 is pushed backward relative to the housing 2, the first support rod 13 moves backward away from the opening of the housing 2 under the action of the movable frame 4, causing the first pulling member 31, which bypasses the first support rod 13, to pull the base 21 backward along the first guide rail 101 to approach the first support rod 13, thereby switching the separation mechanism 20 from the stacked state to the unfolded state.

[0080] Optionally, such as Figure 3 , Figure 5 , Figure 8 as well as Figure 9 As shown, the limiting and guiding mechanism 10 also includes a first pulley 15 rotatably disposed on the first support rod 13 and a second pulley 16 rotatably disposed on the second support rod 14; the first pulling member 31 is wrapped around the first pulley 15 to reduce the frictional force of the first pulling member 31 relative to the first support rod 13; the second pulling member 32 is wrapped around the second pulley 16 to reduce the frictional force of the second pulling member 32 relative to the second support rod 14, which helps to reduce the burden of pushing and pulling the movable frame 4.

[0081] It is worth noting that the first pulling member 31 and the second pulling member 32 mentioned in this application can be, but are not limited to, a pull rope, chain, or belt. For example, the first pulling member 31 and the second pulling member 32 can be provided by the same pull rope, simply by fixing the middle part of the pull rope to the base 21, and fixing both ends of the pull rope to the housing 2 after passing over the first pulley 15 and the second pulley 16 respectively. It is understood that the first pulling member 31 and the second pulling member 32 are both fixedly connected to the side wall of the housing 2 near the opening to prevent the first pulling member 31 and the second pulling member 32 from loosening and detaching from the first pulley 15 and the second pulley 16 during the pulling process, thus ensuring that the automatic placement device 1 can operate stably and reliably.

[0082] In addition, such as Figures 3 to 9 As shown, the base 21 of the separation mechanism 20 may include a support frame 211 slidably attached to the first guide rail 101 and used to support the tableware W, and a first guide post 212 fixedly connected to the support frame 211 and arranged perpendicular to the support frame 211; a plurality of separation racks 23 are slidably fitted onto the first guide post 212 to guide the plurality of separation racks 23 to move along a direction perpendicular to the support frame 211, so as to move along the first guide rail 101 with the support frame 211.

[0083] Similarly, such as Figures 3 to 9 As shown, the top frame 22 of the separation mechanism 20 may include a limiting frame 221 slidably attached to the second guide rail 102 and a second guide post 222 fixedly connected to the limiting frame 221 and arranged perpendicular to the limiting frame 221; a plurality of separation frames 23 are slidably fitted onto the second guide post 222 to guide the plurality of separation frames 23 to move along a direction perpendicular to the limiting frame 221, so as to move along the second guide rail 102 with the limiting frame 221.

[0084] It is worth noting that, such as Figures 3 to 9 As shown, the first guide post 212 and the second guide post 222 are parallel to each other and are staggered on each separation frame 23. This ensures that the multiple separation frames 23 are always arranged in a direction perpendicular to the support frame 211 and the limiting frame 221, and also prevents structural interference between the first guide post 212 and the second guide post 222 when they are stacked.

[0085] In addition, such as Figures 3 to 9As shown, the base 21 may further include a first roller 213 rotatably disposed on the support frame 211 and rollingly overlapping with the first guide rail 101; similarly, the top frame 22 may further include a second roller 223 rotatably disposed on the limiting frame 221 and rollingly overlapping with the second guide rail 102. It is understood that the rolling overlap mentioned in this application refers to the roller rolling on the guide rail, thus riding on the guide rail, which helps reduce friction between the two and prevents derailment. Of course, in other examples of this application, the first roller 213 and the second roller 223 may be fixed to the support frame 211 and the limiting frame 221 respectively, or may be replaced by a slider or a sliding post, which can still reduce friction to a certain extent; this application will not elaborate further on this.

[0086] Optionally, such as Figures 3 to 9 As shown, the base 21 has two first rollers 213, which are rotatably mounted on the left and right sides of the support frame 211 and respectively roll and overlap with the two first guide rails 101. Similarly, the top frame 22 has two second rollers 223, which are rotatably mounted on the left and right sides of the limiting frame 221 and respectively roll and overlap with the two second guide rails 102. Thus, as... Figure 8 and Figure 9 As shown, the two first rollers 213 can roll back and forth along the two first guide rails 101 under the pull of the linkage mechanism 30, so as to drive the carrier frame 211 to move back and forth along the first guide rail 101; at the same time, the two second rollers 223 will roll up and down along the two second guide rails 102, so as to drive the limiting frame 221 to move up and down along the second guide rail 102, so that the limiting frame 221 and the carrier frame 211 are closer to each other or further away from each other, thereby realizing the state switching of the separation mechanism 20.

[0087] Accordingly, such as Figures 3 to 9 As shown, the separation mechanism 20 can be implemented with two first guide posts 212 and two second guide posts 222. The two first guide posts 212 are fixedly mounted parallel to each other on the left and right sides of the support frame 211, and the two second guide posts 222 are fixedly mounted parallel to each other on the left and right sides of the limiting frame 221. At the same time, each separation frame 23 can be slidably fitted onto the two first guide posts 212 and the two second guide posts 222, so as to guide each separation frame 23 to slide in a specific direction while preventing each separation frame 23 from rotating relative to the guide posts, ensuring the overall structural stability of the separation mechanism 20 and better separating each piece of tableware W.

[0088] Optionally, such as Figure 4 and Figure 6As shown, each separator 23 includes a connecting beam 231 and a pair of separator arms 232 extending in the same direction from opposite ends of the connecting beam 231; each separator arm 232 is slidably fitted onto a corresponding first guide post 212 and second guide post 222 for separating two adjacent cutlery W.

[0089] It is worth noting that, such as Figure 4 and Figure 6 As shown, the separation mechanism 20 may further include a spacing constraint member 24, which is connected in sequence to the base 21, the plurality of separation frames 23 and the top frame 22, and is used to constrain the maximum spacing between two adjacent separation frames 23 while pulling the plurality of separation frames 23 apart when unfolded.

[0090] Optionally, such as Figure 4 and Figure 6 As shown, the spacing constraint 24 in the separation mechanism 20 can be implemented as a flexible element such as a pull rope or chain. The flexible element is fixedly connected to the base 21, the multiple separation frames 23 and the top frame 22 in sequence. It can be straightened when unfolded to pull the multiple separation frames 23 apart from each other, while constraining the maximum spacing between two adjacent separation frames 23. It can also be bent when stacked to avoid blocking the multiple separation frames 23 from being stacked together.

[0091] It is worth noting that in some examples of this application, the spacing constraint 24 can also be implemented as multiple rigid members such as tie rods or connecting rods, with each rigid member hinged at both ends to any two adjacent components among the base 21, multiple separation frames 23, and the top frame 22 to form a scissor-type linkage mechanism, which can still play the same role as the flexible member. Furthermore, in other embodiments of this application, the spacing constraint 24 can also be implemented as a telescopic sleeve or an inflatable airbag, as long as it can constrain the maximum spacing while ensuring stacking; this application will not elaborate further on this.

[0092] Preferably, such as Figure 6 and Figure 9 As shown, the length of the flexible component remains the same between any two adjacent separation racks 23, so that the unfolding distance between any two adjacent separation racks 23 can remain consistent, ensuring that multiple tableware W can be evenly dispersed laterally.

[0093] More preferably, such as Figure 4 and Figure 6 As shown, the separation mechanism 20 has two flexible components; the two flexible components are respectively arranged at the left and right ends of the connecting beam 231, and each flexible component is sequentially fixedly connected to the bearing frame 211, multiple connecting beams 231 and the limiting frame 221, which helps to improve the accuracy of the spacing constraint.

[0094] It is worth noting that, in the above embodiments of this application, such as Figure 1 and Figure 2 As shown, the door 3 is rotatably connected to the box 2, so as to open or close the opening of the box 2 by flipping. Of course, in other embodiments of this application, the door 3 may also be fixedly connected to the movable frame 4, so as to open or close the opening of the box 2 by pushing or pulling.

[0095] Furthermore, the movable frame 4 in the cleaning machine of this application can be manually pushed and pulled or automatically pushed and pulled by a drive mechanism, which will not be described in detail here.

[0096] It is worth mentioning that another embodiment of this application can further provide a smart kitchen, which may include the aforementioned washing machine and a robot that works in conjunction with the washing machine. The robot is used to push and pull the movable rack 4 and pick up and place multiple stacked tableware W to the base 21 of the separation mechanism 20 in the automatic placement device 1. In this way, in the smart kitchen of this application, the robot only needs to push and pull the movable rack 4 relative to the box 2 to automatically complete the arrangement and placement of tableware; this not only greatly reduces the burden of manual operation, but also effectively reduces the hardware configuration and algorithm control requirements of the robot in terms of visual recognition and precise positioning, reduces the overall machine development and production costs, and improves the stability and versatility of equipment operation.

[0097] In addition, the robot mentioned in this application can also open or close doors, so as to completely free up human labor.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
