Abstract
Description
Technical Field
[0001] This application relates to the technical field of dishwashers, and particularly to a dishwasher that can place tableware messily. Background Art
[0002] Currently, the mainstream dishwashers on the market adopt the cleaning solution of the spray arm in Comparative Document 1 (CN114903402A). In this technical solution, since the direction of water flushing is fixed, it is necessary for manual labor to classify and place the tableware in the designated area of the dishwasher, and the tableware needs to be placed in a specified posture and angle, which makes it inconvenient to use. At the same time, because the direction of water flushing is fixed, there are cleaning dead ends for tableware such as rice bowls and vegetable bowls with a relatively large curvature, resulting in incomplete cleaning of the tableware. Or when there is a slight deviation in the posture and angle of the manually placed tableware, new cleaning dead ends will also be generated, leading to incomplete cleaning of the tableware. In this solution, the water pressure cleans all tableware at the same time, resulting in a very small water pressure finally allocated to each tableware, making it impossible to clean relatively sticky stains. Therefore, before the tableware is put into the dishwasher, it is necessary for manual labor to first separate and remove the relatively sticky stains from the tableware before it can be put into the dishwasher for cleaning, which further causes inconvenience in use. Because the water pressure finally allocated to each tableware is very small, the cleaning time is very long, up to about 1 hour. When this solution is used to clean tableware, it is necessary to add detergent, and there is a potential food safety risk that the tableware still has detergent residues after cleaning.
[0003] In the exploration, there are also solutions that have not been widely popularized and sold, such as the technical solutions in Comparative Document 2 (CN116269120A) or Comparative Document 3 (CN108354564A). Compared with the cleaning solution of the spray arm in Comparative Document 1, Comparative Document 2 and Comparative Document 3 support the messy placement of tableware, solving the problems of inconvenient use, incomplete cleaning, and long cleaning time. However, because both Comparative Document 2 and Comparative Document 3 adopt the technical solution of robotic arms, the basic price of one robotic arm is about 50,000 to 100,000 yuan. For ordinary families, there are defects of extremely high costs and inability to be widely popularized. Summary of the Invention
[0004] Aiming at the above problems, the purpose of this application is to provide a dishwasher that can place tableware messily to solve the above problems.
[0005] To achieve the above purpose, this application adopts the following technical solution: A dishwasher that can place tableware messily includes a data calculation and processing module, a cleaning module. The dishwasher further includes a linear motion mechanism in three directions or three spatial dimensions, a rotational motion mechanism with two rotation axes, a gripper, and a tableware positioning module.
[0006] Optionally, the linear motion mechanism in the three directions or three spatial dimensions includes an X-axis linear motion mechanism, a Y-axis linear motion mechanism, and a Z-axis linear motion mechanism, where the three axes of X, Y, and Z are perpendicular or approximately perpendicular to each other.
[0007] Optionally, the Z-axis linear motion mechanism is fixedly installed on the Y-axis linear motion mechanism, and the Y-axis linear motion mechanism is fixedly installed on the X-axis linear motion mechanism.
[0008] Optionally, the rotary motion mechanism with two rotation axes includes a first rotary motion mechanism and a second rotary motion mechanism, and the rotation planes of the first rotary motion mechanism and the second rotary motion mechanism are perpendicular or approximately perpendicular to each other.
[0009] Optionally, one end of the rotary motion mechanism is fixedly installed at the lower end of the Z-axis linear motion mechanism, and the gripper is fixedly installed at the other end of the rotary motion mechanism.
[0010] Optionally, the tableware positioning module includes a 3D camera, which is used to identify and position the tableware and guide the gripper to pick up the tableware.
[0011] Optionally, the tableware positioning module is fixedly installed on the Z-axis linear motion mechanism.
[0012] Optionally, the cleaning module adopts the cleaning method of high-temperature and high-pressure water vapor.
[0013] Beneficial effects:
[0014] Compared with Comparative Document 2 (CN116269120A) or Comparative Document 3 (CN108354564A), the present application provides a technical solution with a different technical concept to achieve the cleaning of randomly placed tableware. Compared with the technical solutions using robotic arms in both Comparative Document 2 and Comparative Document 3, the basic price of a robotic arm is about 50,000 to 100,000. The present application greatly reduces the cost, which can be within 10,000, solving the cost and price problems for the large-scale popularization of dishwashers.
[0015] Compared with the cleaning solution of the spray arm in Comparative Document 1, which is also the mainstream dishwasher currently on the market, the cost of this application is not much different. However, this application solves the following several defects existing in the technical solution of Comparative Document 1: Defect 1: The tableware is not thoroughly cleaned or not cleaned cleanly. This application can clean the tableware 360 degrees without dead angles and clean the tableware thoroughly; Defect 2: It is not convenient to operate and use. The tableware needs to be sorted and placed in the designated area of the dishwasher and the tableware needs to be placed in the designated posture and angle. This application supports the messy placement of tableware and is extremely convenient to operate; Defect 3: It is not convenient to operate and use. All tableware needs to be manually separated and removed from the relatively sticky stains on the tableware before being put into the dishwasher for cleaning. This application uses high-temperature and high-pressure steam and all water pressures act on only one tableware at the same time. The water pressure during the cleaning of the tableware is large enough to thoroughly clean the relatively sticky stains, and there is no need to manually separate and remove the sticky stains before putting them into the dishwasher, further improving the convenience of operation; Defect 4: The cleaning time is very long, up to about 1 hour. This application has a very fast cleaning time, and all the tableware for a family of four can be cleaned in 5 minutes; Defect 5: There is a risk of detergent residue after the tableware is cleaned. This application does not require detergent to clean the tableware, only uses high-temperature and high-pressure steam for cleaning. After cleaning the tableware, there is no detergent residue. At the same time, the high-temperature and high-pressure steam has an automatic disinfection function.
[0016] There is an electric rice cooker for cooking at home, a refrigerator for storing food, air conditioners and electric fans in summer. Basically, there are corresponding household appliances to meet the various needs of families. At present, dishwashing is a relatively big demand that plagues Chinese families and has not been solved. Because of the above defects in current dishwashers, almost no one uses them, and the popularization rate is less than 5% (this data has a rigorous and reliable source). Therefore, automatic dishwashing at home is a technical problem that people have always been eager to solve but have never been successful. This application not only solves almost all the defects of the mainstream dishwasher technical solutions currently on the market (such as: Comparative Document 1), but also solves the problem of the extremely high cost and price of Comparative Document 2 and Comparative Document 3. And this application has controlled the cost and price, and many families can afford it. Therefore, this invention solves the technical problem that people have always been eager to solve but have never been successful.
[0017] Due to the technical features of this invention, on the premise that the cost is controllable and can meet the consumption ability of most consumers, this invention solves almost all the defects of existing mainstream dishwashers, and the market is huge (more than a 100 billion-level market), and the popularization rate is less than 5%. Basically, it is a super blue ocean market. It truly achieves convenient, thorough, fast cleaning of tableware, no use of any detergent and healthy use. Therefore, this invention is very likely to achieve great success commercially.
[0018] In this application, by combining the technical solutions of linear motion mechanisms in three directions or three spatial dimensions, rotary motion mechanisms with two rotation axes, grippers, tableware positioning systems, and tableware cleaning systems, after combination, each technical feature supports each other functionally; because as long as one of the technical solutions is missing, the present invention cannot achieve the technical effects described in this application, so each technical feature of this combination supports each other functionally and also achieves new technical effects. Although each individual technical feature itself is completely or partially known, it does not affect the evaluation of the inventiveness of this invention. Brief Description of the Drawings

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only some of the embodiments of this application, rather than all of them. Usually, the components of the embodiments of this application described and illustrated in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents the selected embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.
[0025] In view of the problems existing in the prior art, the present application provides a dishwasher capable of randomly placing tableware to solve this problem, which will be specifically described below with reference to the accompanying drawings. The dishwasher provided by the present application includes a data calculation and processing module (for processing information such as image data) and a cleaning module 50. Preferably, the cleaning module 50 adopts a high-temperature and high-pressure steam cleaning method.
[0026] Further, referring to Figures 1 to 5 , the dishwasher 100 further includes a linear motion mechanism 10 in three directions or three spatial dimensions, a gripper 30, and a tableware positioning module 40. The linear motion mechanism 10 includes an X-axis linear motion mechanism 11, a Y-axis linear motion mechanism 12, and a Z-axis linear motion mechanism 13 (which can also be called a vertical motion mechanism). Among them, the three axes of the X-axis, Y-axis, and Z-axis are perpendicular or approximately perpendicular to each other. The Z-axis linear motion mechanism 13 is fixedly installed on the Y-axis linear motion mechanism 12, and the Y-axis linear motion mechanism 12 is fixedly installed on the X-axis linear motion mechanism 11. In this way, by controlling the movements of the X-axis linear motion mechanism 11, the Y-axis linear motion mechanism 12, and the Z-axis linear motion mechanism 13, the gripper 30 can be controlled to move to any position in the working space of the dishwasher 100, so that the gripper 30 can find and / or pick up tableware at any position in the working space of the dishwasher 100.
[0027] Further, the dishwasher 100 further includes a rotational motion mechanism 20. The rotational motion mechanism 20 includes a first rotational motion mechanism 21 and a second rotational motion mechanism 22. The rotational planes of the first rotational motion mechanism 21 and the second rotational motion mechanism 22 are perpendicular or approximately perpendicular to each other. The rotational plane refers to the cross-section of the cylinder formed by the cylindrical surface obtained through rotational motion. Referring to Figure 1 and Figure 5 , the rotational plane of the first rotational motion mechanism 21 is a horizontal plane, and the rotational plane of the first rotational motion mechanism 21 is perpendicular to its rotational axis. The rotational plane of the second rotational motion mechanism 22 is a vertical plane, and the rotational plane of the second rotational motion mechanism 22 is perpendicular to its rotational axis. One end of the rotational motion mechanism 20 is fixedly installed at the lower end of the Z-axis linear motion mechanism 13, and the gripper 30 is fixed at the other end of the rotational motion mechanism 20. In this way, by controlling the rotational motions of the first rotational motion mechanism 21 and the second rotational motion mechanism 22, the gripper 30 can be controlled to pick up tableware at any angle or posture.
[0028] Further, the lower end of the Z-axis linear motion mechanism 13 is fixedly connected to the first rotational motion mechanism 21. The first rotational motion mechanism 21 is connected to the second rotational motion mechanism 22, and the gripper 30 is fixedly installed on the second rotational motion mechanism 22.
[0029] Furthermore, the tableware positioning module 40 is fixedly installed on the Z-axis linear motion mechanism 13. The tableware positioning module 40 includes a 3D camera. In this way, the 3D camera can move within the working space of the dishwasher 100 along with the movement of the linear motion mechanism 10 in three directions or three spatial dimensions. Thus, the shooting range of the 3D camera is increased and it can reach all areas of the working space of the dishwasher 100. In this way, the 3D camera can identify and position any tableware, and thus can identify the position and posture of any tableware within the space of the dishwasher 100.
[0030] Furthermore, the position and posture of the tableware can be determined through the tableware positioning module 40; by controlling the movement of the linear motion mechanism 10 in three directions or three spatial dimensions, the gripper 30 can be moved to any position of any tableware; and then by controlling the movement of the rotary motion mechanism 20 with two rotation axes, the gripper 30 can be moved to any angle or posture required to pick up any tableware in the working space of the dishwasher 100. In this way, no matter how messy the tableware is placed, the gripper 30 can pick up the tableware to be picked up for cleaning. Therefore, there is no need for manual placement of the tableware. When the target tableware is picked up and transferred to the washing area for cleaning, the target tableware can also be adjusted to different cleaning angles for 360-degree dead-angle-free cleaning by controlling the movement of the rotary motion mechanism 20. At the same time, the steam pressure only acts on a single tableware at a time, maximizing the impact force on the tableware, so that it can be cleaned more cleanly, thoroughly, and without residue.
[0031] Furthermore, the gripper 30 is preferably an electric gripper. The dishwasher 100 further includes a to-be-washed area (area for placing soiled tableware), a clean area (area for placing washed tableware), and a washing area (area for cleaning tableware). The electric gripper is used to transfer each tableware from the to-be-washed area to the washing area for separate cleaning and / or transfer the washed tableware from the washing area to the clean area.
[0032] The cleaning method of this dishwasher adopts the method of cleaning tableware one by one separately. The process is roughly as follows: The user randomly places the tableware to be washed in the area to be washed. The 3D camera identifies and locates the tableware. The linear motion mechanism 10 drives the electric gripper to move to the tableware according to the located position information. The electric gripper adjusts the angle of gripping the tableware under the drive of the rotary motion mechanism 20, and grips one of the tableware. After gripping, it is transferred to near the cleaning module 50 in the washing area for separate cleaning. Preferably, the cleaning module 50 can spray high-temperature steam or water to clean the tableware. During the cleaning process, the rotary motion mechanism 20 drives the electric gripper to rotate, so as to adjust the tableware to different cleaning angles for 360-degree dead-angle-free cleaning. After the cleaning is completed, the tableware is placed in the clean area, and then the electric gripper is driven to grip the next tableware for cleaning. This process is repeated until the 3D camera cannot identify the tableware. In this way, the cleaning work of all tableware can be completed.
