[0036] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details. In some instances, methods, means, elements and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present disclosure.

[0037] Unless otherwise specified, the orientation "front" herein indicates the direction in which the dishwasher faces the user, and the orientation "rear" indicates the direction in which the dishwasher is away from the user.

[0038] A dishwasher is a device for automatically cleaning tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. Generally, it includes a washing chamber, and a dish rack is arranged in the washing chamber. The dish rack is used to place the tableware to be cleaned. The way of placing bowls and dishes is an important factor affecting the cleaning degree of the dishwasher. If the position of the bowls and dishes is not appropriate, such as placing a bowl in the cleaning position of a dish, or overlapping the bowls and dishes, etc., it will affect the cleaning degree of the bowls and dishes.

[0039] Currently, in order to make the best use of space to place bowls and dishes as much as possible, the dish rack is designed complexly and the space is tight. When users actually use the dishwasher, they cannot intuitively obtain obvious instructions for placing bowls and dishes through the dish rack, resulting in difficult operation when using the dishwasher, and the cleaning effect of bowls and dishes is easily affected due to the placement problem. Although the dishwasher will introduce the placement areas and placement methods of various tableware in the instruction manual, the complex placement steps will lead to a high learning difficulty for users, and referring to the instructions in the manual when using the dishwasher will also increase the operation difficulty of users, affecting the efficiency of the dishwashing work and the user experience.

[0040] To solve the above technical problems, the embodiments of the present disclosure provide a sink - type dishwasher with a projection function. When the user uses the dishwasher, the dishwasher generates a projection image, and the projection image is used to prompt the placement position and placement method of bowls and dishes on the dish rack 60. The user intuitively learns and correctly places according to the prompted projection image, so as to ensure the cleaning degree of the bowls and dishes.

[0041] Figure 1 The side cross - sectional structure diagram of the sink - type dishwasher is shown, as Figure 1 shown, the sink - type dishwasher includes a dishwasher main body, a dish rack 60, a door body 10, and a projection module 30. The dish rack 60 is arranged inside the dishwasher main body, the door body 10 is rotatably installed on the top of the dishwasher main body, and the projection module 30 is arranged on the dishwasher main body. The projection module 30 is used to project a target pattern towards the inner wall side of the door body 10 when the door body 10 is opened. The target pattern indicates the placement position and placement method of bowls and dishes on the dish rack 60. Based on the above structure, when the user uses the dishwasher, first open the door body 10, then the projection module 30 projects a target pattern towards the inner wall side of the door body 10. The user places bowls and dishes and other tableware at the corresponding positions according to the prompt of the target pattern in the correct placement method. After the placement is completed, close the door body 10, and the dishwasher main body cleans the tableware.

[0042] The reason for choosing to set the projection module 30 on the sink - type dishwasher in this embodiment is that the door 10 of the sink - type dishwasher is set on the top of the dishwasher main body. After the door 10 is opened, it can be set vertically. The projection module 30 can project towards the inner wall side of the door 10. When the user places the tableware to be washed, they can directly look at the door 10 to obtain placement guidance, reducing the difficulty and learning cost for the user to use the dishwasher, thereby improving the user experience. It should be understood that in some possible implementation manners, the projection module 30 can also be configured to generate projections in other directions, for example, the ground, the wall, the outer side of the dishwasher main body, etc.

[0043] In a sink - type dishwasher, the weight of the door 10 is generally large, and there are sealing parts that cooperate with each other between the dishwasher main body and the door 10 to ensure that no gas or liquid leaks during the cleaning process. Therefore, the initial force required to open the door 10 of the sink - type dishwasher is large. Also, because the door 10 is rotatably installed on the top of the dishwasher main body and needs to be pulled up when opening the door, this causes difficulty for the user to open the door. To facilitate the user to open the door, please refer to Figure 1 , the sink - type dishwasher of the present disclosure embodiment further includes a lifting module. The lifting module is fixedly installed on the dishwasher main body, and the lifting module is used to lift the door 10.

[0044] In this embodiment, the lifting module can be connected to the control board of the sink - type dishwasher. When the user uses the dishwasher, by sending an opening instruction through the control board, the control board sends a control signal to the lifting module to make the lifting module rise and lift the door 10 until the door 10 rotates a certain angle. Then the user manually opens the door 10. At this time, the force required for the user to open the door is less than the initial opening force, reducing the difficulty for the user to open the door. In some possible implementation manners, the lifting module can also be provided with a separate switch control for controlling the lifting height of the lifting module.

[0045] Furthermore, the lifting module and the projection module 30 can be integrally arranged, that is, the above - mentioned projection module 30 is installed on the lifting module. Integrally arranging the lifting module and the projection module 30 can avoid the projection module 30 interfering with the structure of the dishwasher main body and the door 10. When the dishwasher is in the closed state, the lifting module lowers its height and retracts the projection module 30. When the dishwasher needs to open the door, the lifting module lifts the door 10 and drives the projection module 30 to rise, so that the projection module 30 can be aligned with the inner wall side of the door 10.

[0046] The present disclosure embodiment does not limit the specific selection of the lifting module. That is to say, the lifting module can be a single transmission part with linear expansion and contraction, such as a cylinder, a hydraulic cylinder, an electric telescopic rod, etc., or a component that realizes linear expansion and contraction based on a mechanical structure, for example, a crank - connecting rod.

[0047] In a specific implementation manner, please refer toFigure 1 The lifting module is configured as a motor-driven lift rod 80 structure, specifically including a first motor 70 and a lift rod 80 connected to the first motor 70, and the first motor 70 is used to drive the lift rod 80 to rise and fall. The reason for selecting a motor drive source in this embodiment is that the lifting module needs to provide a large upward force to lift the door body 10 on the one hand, and on the other hand, the lifting module needs to carry the projection module 30 to a specific height to ensure a clear projection image. The selection of a motor drive source can take into account the output driving force, accuracy and speed, and it also has the advantages of simple structure and low cost.

[0048] In a further embodiment, the projection module 30 can be fixedly installed inside the top rod 80, the top rod 80 is provided with a projection hole, the projection lamp of the projection module 30 is aimed at the projection hole, and the projection hole faces the inner wall side of the door body 10. Embedding the projection module 30 inside the top rod 80 can reduce the risk of damage to the projection module 30 during the process of the top rod 80 rising to open the door body 10, and the projection module 30 disposed inside the top rod 80 is also helpful in adjusting the projection screen. In some possible cases, the lifting module and / or the projection module 30 is also provided with a rotating member, the rotating shaft of the rotating member is consistent with the center line of the top rod 80, and the left and right projection direction of the projection module 30 can be adjusted through the rotating shaft.

[0049] In a specific embodiment, please refer to Figure 1 , the door body 10 is set as a rear flip door, that is, the rotating shaft of the door body 10 is set at the rear side of the top of the dishwasher body, and the lifting module is set at the top of the front side of the dishwasher body. Based on the above position setting, when the user uses the dishwasher, the door body 10 is opened and then flipped backwards, and the top rod 80 on the front side of the dishwasher body rises, so that the projection module 30 can project the target pattern on the inner wall side of the door body 10, and the user can just look directly at the target pattern on the inner wall side of the door body 10 when placing the dishes to be washed. Therefore, the above structural position setting is more in line with the user's behavior and can improve the user's experience.

[0050] In the disclosed embodiment, the projection module 30 should project after the door body 10 is fully opened. Projecting too early will lead to energy waste and cause trouble to the user, while projecting too late will also affect the speed at which the user places the tableware. Therefore, a position sensor is also provided on the dishwasher body. The position sensor is used to generate a sensing signal after the door body 10 is opened to a specified angle, and the projection module 30 projects the target pattern according to the sensing signal.

[0051] The disclosed embodiments do not limit the type of position sensor, that is, the position sensor can be a contact sensor or a non-contact sensor. For example, the position sensor can be an angle sensor, a Hall sensor, an optical coupler, an infrared sensor, etc. The disclosed embodiments do not limit the above-mentioned specified angle, which can be the maximum opening angle of the door body 10, or a manually set angle, such as 90°, 60°, etc. In some specific embodiments, the above-mentioned specified angle is selected and configured as the maximum opening angle of the door body 10. When the door body 10 is opened to the maximum angle, the position sensor generates a sensing signal, and the control board of the dishwasher determines that the user needs to place dishes and tableware in the dish rack 60, and controls the projection module 30 to project the target pattern. Correspondingly, when the opening angle of the door body 10 is less than the specified angle, the sensing signal of the position sensor returns to zero, and the control board of the dishwasher determines that the user no longer needs to place dishes and tableware, and then controls the projection module 30 to turn off the projection lamp, and then controls the top rod 80 of the top lifting module to descend, so as to facilitate the door closing operation.

[0052] It is worth noting that the embodiment of the present disclosure needs to project the target pattern onto the inner wall of the door body 10, so the door body 10 should be as close to the vertical direction as possible when it is at the maximum opening angle to ensure the projection effect. Therefore, a limiter is also provided on the dishwasher body, which is used to limit the door body 10 when it is opened to the maximum angle, so that the door body 10 can remain stationary when it is opened to the maximum angle. Please refer to Figure 1 In some possible implementations, the maximum opening angle range of the door body 10 is 90° to 120°.

[0053] In addition, the present disclosure does not limit the door body 10 to be opened manually, that is, the dishwasher can also adopt automatic door opening and closing. Specifically, a door opening module is also provided on the main body of the dishwasher, and the door opening module includes a second motor, which is connected to the rotating shaft of the door body 10 by transmission, and the second motor is used to drive the rotating shaft of the door body 10 to rotate to open the door body 10. Based on the above-mentioned door opening module, the user can realize one-button door opening and closing through the control panel of the dishwasher or other forms of switch controls, which is more convenient for the user to operate.

[0054] In order to further improve the user experience, in some embodiments, the inner wall of the door body 10 is also provided with a screen layer, and the screen layer is used to clearly display the target pattern. This embodiment does not limit the specific selection of the screen layer. For example, the screen layer can be a layer of pigment coating applied to the inner wall of the door body 10, or a glass reflective screen installed on the inner wall of the door body 10, or other forms of screen layers. It should be understood that in order to ensure the projection effect, a screen layer made of dark materials should be selected to ensure that the projected target pattern can be clearly displayed.

[0055] In some possible application scenarios, there is a large amount of placement guidance content regarding the dish rack 60, and a single projection cannot fully contain all the placement guidance. Or, the user needs to zoom in to view the placement detail diagram. In these application scenarios, the user needs to change the target pattern. Considering that the user has come into contact with soiled tableware, directly changing the target pattern according to the control panel will contaminate the control panel, and specifically washing hands to change the target pattern will lead to complicated usage steps.

[0056] To solve the above problems, in some possible embodiments, the projection module 30 includes an infrared touch function. Specifically, the projection module 30 is further configured to project function buttons on the inner wall surface of the door body 10. The projection module 30 further includes an image sensing device for obtaining a trigger signal of the function button. For example, when the user needs to switch the target pattern or zoom in on the target pattern, the user directly touches the function button. After the image sensing device senses that the function button is triggered, a corresponding instruction is generated and fed back to the projection module 30, and the projection module 30 executes the corresponding steps. Since the function buttons are projected on the inner wall surface of the door body 10, during the cleaning of the dishwasher, the inner wall surface of the door body 10 belongs to the top surface of the washing chamber of the dishwasher, and the dishwasher will also clean the inner wall surface of the door body 10 while cleaning the tableware, without worrying about the inner wall surface of the door body 10 being contaminated.

[0057] In some other possible embodiments, a voice module is further provided on the dishwasher main body. The voice module is configured to issue a voice prompt to inform the placement position and placement method of the bowls and dishes on the dish rack 60. By combining the voice prompt of the voice module with the target pattern projected by the projection module 30, the user can be better reminded to place the tableware in the correct way.

[0058] Furthermore, the above voice module can also be used to recognize the user's voice commands, and the dishwasher executes corresponding operations according to the recognized voice commands. For example, opening the door, closing the door, adjusting the height of the projection module 30, adjusting the brightness of the projection lamp, switching the target pattern, etc.

[0059] The above-mentioned multiple embodiments have fully and detailedly described the solution of setting the projection module 30 on the sink-type dishwasher to project a target pattern to prompt the user to place the tableware correctly. It should be understood that the projection module 30 can also be adaptively set on other types of dishwashers.

[0060] In addition, the present disclosure embodiment selects the projection module 30 as the main body for generating the prompt screen, and its advantage lies in that it can reduce the manufacturing cost of the dishwasher. For a sink-type dishwasher without a projection function, the above function effect can also be achieved by adding modular projection parts and lifting parts.

[0061] It should be understood that the projection module 30 of the present disclosure can also be replaced with other display devices. For example, in a possible embodiment, an electronic display screen can be provided on a sink-type dishwasher. The electronic display screen is provided on the inner wall side of the door body 10, and a protection component is also provided on the inner wall side of the door body 10. The protection component is used to protect the electronic display screen from being damaged by gas or liquid erosion. Based on the sink-type dishwasher configured with the above structure, after the user opens the door body 10, the electronic display screen lights up and displays a target pattern, and the target pattern indicates the placement position and placement method of the dishes on the dish rack 60.

[0062] The various embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
