Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a tableware cleaning machine. Background Technology

[0002] A dishwashing machine, also known as a dishwasher, is a specialized device for cleaning tableware and is widely used in homes, restaurants, hotels, and other establishments. Dishwashing machines typically employ high-pressure water spray, rotating spray arms, and ultrasonic technologies to evenly spray hot water and detergent onto the surface of the tableware, removing grease, stains, and food residue through mechanical rinsing and chemical action. Some dishwashing machines may also be equipped with a drying function, using hot air or residual heat to quickly dry the tableware.

[0003] To meet diverse washing needs and achieve better cleaning results while protecting dishes and saving energy and water, multiple washing modes are often required. In existing technology, a camera is installed in the dishwasher to capture information about contaminants on the visible areas of the dishes. This information is then output to a controller, which automatically selects the appropriate washing mode based on this information.

[0004] However, in the identification of contaminants on dishes to be washed, the image information that can be collected for the dishes placed to be washed is only the part that is not covered. The contaminant situation in the covered part is unknown. When there is a lot of contaminant in the covered part, the identification of the degree of dirtiness of the dishes to be washed is inaccurate. This will cause the washing machine to deviate in identifying the overall degree of dirtiness of the dishes, thus affecting the washing effect. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0025] Please refer to Figures 1-4As shown in the figure, the present application discloses a dishwashing machine, which includes a housing 1 and a door panel 2. The door panel 2 is hinged to the front end of the housing 1. An inner container is provided inside the housing 1. A lower bowl basket 4 and a spraying component are arranged in the inner container. The lower bowl basket 4 is slidably arranged in the inner container. The spraying component is used to clean the objects to be cleaned in the lower bowl basket 4. The lower bowl basket 4 includes a first area, a second area, a third area and a fourth area. An information collection component is arranged on the door panel 2 or the inner container. Specifically, the information collection component is at least one camera. The information collection component is used to obtain the quantity information of the objects to be cleaned in each area of the lower bowl basket 4. The information collection component and the spraying component are respectively connected to a controller. In the present application, the lower bowl basket 4 is divided into four areas. The information collection component obtains the quantity information of the objects to be cleaned in each area of the lower bowl basket 4 and transmits the quantity information to the controller. The controller then controls the spraying component to clean the objects to be cleaned in the lower bowl basket 4 in a targeted manner, reducing the ineffective cleaning of the vacant areas and strengthening the cleaning of the areas where the quantity of dishes is concentrated, thereby improving the cleaning efficiency and effectively reducing the waste of water resources. Compared with the prior art of obtaining the pollutants on the dishes and cleaning the dishes according to the degree of dirt, in the present application, the information collection component obtains the quantity information of the objects to be cleaned in each area of the lower bowl basket 4, and then the spraying component performs different-intensity cleaning according to the different quantities, so as to ensure that each area with dishes is sufficiently cleaned, especially the areas that are easily blocked or densely arranged.

[0026] The spraying component includes a lower spray arm and a first driving motor connected to the controller. The output shaft of the first driving motor is connected to the lower spray arm. The first driving motor is used to drive the lower spray arm to rotate. The information collection component feeds back the quantity of the objects to be cleaned in each area collected to the controller. The controller dynamically adjusts the spraying angle and rotation speed of the lower spray arm according to the quantity of dishes in different areas to strengthen the cleaning of the areas where the quantity of dishes is concentrated.

[0027] Specifically, the areas of the first area, the second area, the third area and the fourth area are equal, and they are evenly separated along the length direction and the width direction of the lower bowl basket 4. The first area, the second area, the third area and the fourth area are distributed in a "field" shape. The first area is adjacent to the second area and the third area respectively. The fourth area is arranged opposite to the first area along the diagonal direction of the lower bowl basket 4. Such a setting facilitates the information collection component to uniformly and accurately collect information for each area on the one hand, and is also beneficial for the spraying component to clean each area on the other hand.

[0028] Preferably, the camera is a wide-angle camera with a field of view greater than 100°. More preferably, the camera's field of view is 130°. The wide-angle camera configuration covers all four areas of the lower bowl basket 4, allowing a single camera to capture the distribution of tableware throughout the entire lower bowl basket 4, avoiding the cost and complexity of installing multiple cameras. Furthermore, the wider field of view allows for clear identification of the quantity of tableware stacked, tilted, or located at the edges of each area, improving detection accuracy.

[0029] In some embodiments, the housing 1 has two opposite sidewalls with first mounting ports, and the inner liner has a corresponding first through hole. At least one first mounting port is fitted with a camera, which obtains the quantity information of the objects being cleaned in each area of ​​the lower basket 4 through the first through hole. The camera is installed inside the housing 1 (external environment) and observes the inner liner through the first through hole, which can physically isolate high-temperature water vapor and spray water flow, extending the camera's lifespan. To further protect the camera, a transparent protective sleeve is fitted over the camera or a high-temperature resistant hydrophobic coating is applied to the lens surface. The inner liner also has an upper basket 5, which is located above the lower basket 4. The first mounting port is located axially between the upper basket 5 and the lower basket 4, and the distance between the first mounting port and the upper basket 5 is less than the distance between the first mounting port and the lower basket 4. Both first mounting ports are fitted with cameras.

[0030] Preferably, the relationship between the camera's mounting tilt angle θ and mounting height H and the inner liner width D is: θ = arctan(H / D). This setting avoids the problem of the top of the tableware obscuring the bottom when shooting vertically, ensuring the integrity and accuracy of the image information. In addition, the tilted camera setting can also avoid direct sunlight from the ceiling light or mirror reflections from the water surface, reducing image noise and improving the reliability and accuracy of the camera during operation.

[0031] In some embodiments, a second mounting opening is provided on the top wall of the housing 1 near the door panel 2, with the opening of the second mounting opening facing downwards, and the camera is mounted at the second mounting opening. To protect the camera, a transparent protective cover is fitted over the camera or a high-temperature resistant hydrophobic coating is applied to the surface of the camera lens. Integrating the camera into the top wall of the housing 1 does not occupy space in the inner liner or side walls. Furthermore, placing the camera here makes it easier to disassemble and maintain the camera.

[0032] In some embodiments, a third mounting opening 3 is provided on the side of the door panel 2 near the inner liner, and the camera is mounted in the third mounting opening 3. To avoid interference with the upper basket 5, the third mounting opening 3 is axially located between the upper basket 5 and the lower basket 4. By mounting the camera on the door panel 2, the camera can be easily cleaned and maintained after the door panel 2 is opened. Mounting the camera on the door panel eliminates the need for additional through holes in the inner liner, simplifying the inner liner manufacturing process. To protect the camera, a transparent protective sleeve is fitted over the camera, or a high-temperature resistant hydrophobic coating is applied to the lens surface.

[0033] Preferably, the distance between the camera and the left side of the door panel 2 is L1, the distance between the camera and the right side of the door panel 2 is L2, L1=L2, and the distance between the camera and the lower basket 4 in the axial direction is L3, 5cm≥L3≥1cm.

[0034] The inner tank also includes a middle spray arm for spraying the lower basket 4. The middle spray arm is located above the lower basket 4, and the lower spray arm is located below the lower basket 4. Both the middle and lower spray arms are connected to a water distribution valve assembly, which is connected to a controller. Specifically, the water distribution valve assembly includes a connecting joint, a water distribution chamber, a valve plate, and a second drive motor for driving the valve plate to rotate. The second drive motor is connected to the controller. The lower spray arm is connected to the water distribution chamber via the connecting joint. The middle spray arm is connected to an inner water pipe, which is also connected to the water distribution chamber via the connecting joint. The valve plate rotates under the drive of the second drive motor, controlling whether the water distribution chamber is connected to the middle and lower spray arms. The specific connection methods of the connecting joint, the water distribution chamber, and the valve plate, as well as the specific connection method of the second drive motor and the valve plate, are existing technologies and will not be described in detail here. When the water distribution chamber is connected to the middle spray arm, the middle spray arm performs spraying operations; when the water distribution chamber is connected to the lower spray arm, the lower spray arm performs spraying operations. Essentially, the controller controls the rotation of the valve plates by controlling the motor, thereby controlling whether the middle and lower spray arms spray.

[0035] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
