For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise stated, "a plurality" means two or more.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0062] In the current range hood display hall or exhibition hall, the display device can clean the impeller of the range hood to show the intuitive effect after cleaning. However, the existing display device only cleans the impeller of the fan, so it can only show the cleaning condition of the impeller after cleaning, resulting in limitations in the cleaning and display of the display device and poor display effects.

[0063] To solve the above problems, please refer to Figures 1 to 3 , a contrast display device 100 for the main cleaning effect is proposed in the first aspect of the present application. In the embodiment of the present application, the contrast display device 100 includes a support assembly 10, at least two sets of components to be cleaned 20, and at least two sets of cleaning components 30.

[0064] Among them, the support assembly 10 serves as the bearing body of the contrast display device 100 for bearing and fixing other components of the contrast display device 100. The overall outer contour of the support assembly 10 can be set in a square shape, so that it can be stably placed on a desktop such as a display stand.

[0065] The components to be cleaned 20 are arranged on the support assembly 10. Each component to be cleaned 20 includes a light-transmitting cover 21 and an impeller 22 arranged in the light-transmitting cover 21. It can be understood that the outer contour of the impeller 22 is generally arranged in a circular column shape, and the impeller 22 is provided with a plurality of blades 221. The plurality of blades 221 are arranged in a ring and define an inner cavity 222. The outer contour of the light-transmitting cover 21 is arranged in a circular tube shape, which not only enables the light-transmitting cover 21 to better fit and cover the impeller 22, but also makes the light-transmitting cover 21 more similar to the outer shell of the impeller 22. At the same time, the outer peripheral surface of the light-transmitting cover 21 is arranged as an arc surface to reduce the situation of cutting the installer during installation. Of course, the outer contour of the light-transmitting cover 21 can also be arranged in a rectangular block shape as long as it can achieve the state of covering the impeller 22.

[0066] Before cleaning and displaying, oil stains can be sprayed or coated on the inner wall surface of the impeller 22 and the transparent cover shell. The oil stains can be real cooking oil stains or other oil stains, so as to clearly observe the cleaning situation of the oil stains adhering to the inner wall surface of the impeller 22 and the transparent cover shell subsequently. The light-transmitting cover shell 21, regarded as the outer shell of the impeller 22, can be made of transparent or translucent materials, so that the cleaning situation of the oil stains in the internal space can be clearly observed. Specifically, it can be made of transparent plastic materials such as polycarbonate or polystyrene. Polycarbonate is a transparent plastic with good strength and heat resistance. It is suitable for many industrial and consumer product applications, providing good light transmittance and impact resistance. Polystyrene is an affordable transparent plastic, suitable for some low-cost applications. Of course, the present invention is not limited thereto, and the transparent cover shell can also be made of glass materials, such as acrylic glass, tempered glass or plexiglass. The glass material can also provide excellent optical transparency and hardness. The impeller 22 can be arranged in the middle of the light-transmitting cover shell 21, and the outer periphery of the impeller 22 is spaced from the inner wall surface of the light-transmitting cover shell 21, so that it is not only convenient to directly observe the cleaning situation of the impeller 22 from outside the light-transmitting cover shell 21, but also when the impeller 22 needs to be rotated for cleaning, the situation of the impeller 22 rotating and interfering with the light-transmitting cover shell 21 can be effectively reduced.

[0067] The cleaning assembly 30 is arranged on the support assembly 10, and the number of the cleaning assemblies 30 is the same as that of the components to be cleaned 30. In this way, multiple cleaning assemblies 30 can be correspondingly connected to multiple components to be cleaned 20 one by one, and one cleaning assembly 30 is used to clean one component to be cleaned 20. Based on the above embodiments, the cleaning effect comparison and display device 100 of the present application simultaneously cleans the light-transmitting cover shell 21 of the component to be cleaned 20 and the impeller 22 located inside the light-transmitting cover shell 21 through the cleaning assembly. Such a design fully considers the cleaning requirements outside the impeller 22, simulates the cleaning by regarding the light-transmitting cover shell 21 as the outer shell of the impeller 22, so as to expand the cleaning range of the comparison and display device 100, and subsequently, the cleaning situations of the impeller 22 and the light-transmitting cover shell 21 can be directly observed through the light-transmitting cover shell 21, so as to intuitively display the cleaning effects of the light-transmitting cover shell 21 and the impeller 22, making the cleaning display of the comparison and display device 100 more comprehensive, so as to realize the authenticity and diversity of the cleaning display.

[0068] In some structural forms, refer to Figure 2, the component to be cleaned 20 further includes a plate to be cleaned 25, and the plate to be cleaned 25 is connected to the inner wall surface of the light-transmitting cover 21. It should be noted that the plate to be cleaned 25 can be made of a steel plate with the same material as the volute, and before cleaning, oil stains or other dirt can be adhered to the plate to be cleaned 25. In this way, the plate to be cleaned 25 can be regarded as the wall surface of the volute, so that the comparison and display device 100 of the present application can also simultaneously provide the cleaning condition of the volute outside the impeller 22, so as to further make the cleaning display of the comparison and display device 100 more comprehensive, so as to achieve the authenticity and diversity of the cleaning display.

[0069] It should be noted that the plate to be cleaned 25 can be fixed to the inner wall surface of the light-transmitting cover 21 by means of bonding or clamping, etc., so as to improve the stability of the plate to be cleaned 25.

[0070] In addition, at least two sets of cleaning components 30 can be configured with different cleaning parameters to achieve different cleaning effects on the two components to be cleaned 20, so as to compare and display different cleaning effects through the light-transmitting covers 21 of different groups of components to be cleaned 20 and the impellers 22 of different groups of components to be cleaned 20. Among them, the structures of the cleaning components 30 can adopt the same design, which helps to unify the processing and manufacturing and improve the production efficiency. At the same time, the components to be cleaned 20 can also adopt the same structural settings. Such a design not only simplifies the manufacturing process, but also provides an intuitive way to observe the differences in cleaning effects, so as to eliminate the possibility of different cleaning effects caused by structural differences. So as to facilitate subsequent introduction of different cleaning parameters between the cleaning components 30 and the components to be cleaned 20 with the same structure, and the effect differences under different cleaning conditions can be easily compared and observed. This consistent structural setting not only makes the system easier to maintain and manage, but also provides flexibility for the adjustment and optimization of the cleaning effect. By introducing an adjustable cleaning process, the cleaning comparison display under different cleaning parameters can be intuitively displayed, so as to achieve the comparative display of the cleaning effect.

[0071] In the design of the comparison display device 100, multiple cleaning parameters can be selectively adjusted to optimize the cleaning effect. Optionally, the cleaning parameters include at least one of the type of cleaning agent of the cleaning component 30, the dosage of the cleaning agent, the cleaning duration, and the rotation direction, rotation speed, and rotation duration of the impeller 22. Among them, the type of cleaning agent includes solutions such as water or various cleaning chemicals. The dosage of the cleaning agent refers to the total amount of cleaning agent released during the cleaning process, and its adjustment can affect the intensity and thoroughness of cleaning. The cleaning duration represents the duration of the cleaning process and affects the sufficiency and efficiency of cleaning. At the same time, it can be understood that when cleaning, the impeller 22 mainly cleans the multiple blades 221, and the rotation of the impeller 22 causes the multiple blades 221 to rotate synchronously, so that all of the multiple blades 221 can be cleaned. In this way, different impeller 22 motion parameters can also be configured for the two groups of cleaning components 30 during the cleaning process, such as selecting the rotation direction of the impeller 22 (counterclockwise rotation or clockwise rotation), so as to change the contact position between the cleaning agent and the blade 221, or the rotation speed or rotation duration of the impeller 22 can also be controlled, etc. This method actually applies the control variable method to ensure the reliability of the experiment. This method provides a reliable guarantee for the accuracy of the test data of the comparison display device 100, enabling users to more accurately evaluate the differences in cleaning effects. Through these flexible cleaning parameter adjustments, the performance of the comparison display device 100 can be effectively optimized, and the visualization display of the cleaning effect can be improved.

[0072] With reference to Figure 2 , in some structural forms, the light-transmitting cover shells 21 of the adjacent components 20 to be cleaned are arranged at intervals. In this way, compared with the scheme where the adjacent light-transmitting cover shells 21 are fitted together, by setting the intervals between the light-transmitting cover shells 21 in this application, users can more easily observe the cleaning situation inside the component 20 to be cleaned. Through the intervals, users can directly see the state inside the light-transmitting cover shell 21, including the degree of cleanliness and possible oil stains or other contaminants. At the same time, the arrangement of the intervals between the light-transmitting cover shells 21 also helps to reduce the interference between the cleaning components 30. If the light-transmitting cover shells 21 are fitted together, the cleaning components 30 interfere with each other during the cleaning process, resulting in unnecessary friction or collision. By setting appropriate intervals, this interference can be reduced, and the stability and reliability of the system can be improved. Generally speaking, this design choice aims to provide the cleaning effect while considering the user experience and system stability. Through the interval setting, users can more easily check the cleaning effect, and the operation of the system is also more stable. This structural form may provide better cleaning performance and user-friendliness in practical applications.

[0073] With reference to Figure 2, in some structural forms, the component 20 to be cleaned further includes a motor 23 and an impeller lock nut 24. The motor 23 is connected to the support component 10. Specifically, the housing of the motor 23 can be fixedly connected to the support component 10 in a detachable manner to ensure the stability of the motor 23 after installation. And the motor shaft of the motor 23 extends into the transparent cover 21. The impeller 22 is directly sleeved on the motor shaft of the motor 23, so as to realize the motor 23 driving the impeller 22 to rotate. In order to improve the stability of the connection between the impeller 22 and the motor shaft of the motor 23, the impeller lock nut 24 is installed on the motor shaft to lock the impeller 22, so as to effectively reduce the possibility of the impeller 22 disengaging from the motor shaft.

[0074] Refer to Figures 3 to 5 , in some structural forms, the cleaning component 30 includes a liquid storage container 31, a spray pipe 32 and a driving member 33.

[0075] Among them, the inside of the liquid storage container 31 is provided with a cavity to store the cleaning agent. The liquid storage container 31 can be arranged in a rectangular block shape, so as to be easy to hold during installation, and it is not easy to shake when placed on the support component 10, improving the stability of the setting. And the liquid storage container 31 can be fixedly connected to the support component 10 by detachable connections such as snap connection or screw connection. In this way, the liquid storage container 31 can be removed from the support component 10 and directly replaced with other liquid storage containers 31 to achieve the effect of replenishing the cleaning agent. Of course, a detachable cover plate communicating with the internal cavity can also be directly provided on the liquid storage container 31. In this way, the cleaning agent can be replenished in the liquid storage container 31 after removing the detachable cover plate.

[0076] The spray pipe 32 is connected to the transparent cover 21 and at least partially extends into the transparent cover 21. The spray pipe 32 can be arranged in a slender circular bar shape, so as to reduce the internal space occupied by the transparent cover 21. And the spray pipe 32 can directly open a connection hole at the top of the transparent cover 21, and the spray pipe 32 can pass through the connection hole to extend into the transparent cover 21. It should be noted that after the spray pipe 32 passes through the connection hole, it can be fixed to the connection hole by interference fit. Or, the spray pipe 32 is connected to other components in the transparent cover 21 for fixation. And the part of the spray pipe 32 extending into the transparent cover 21 has spray holes, so that the spray pipe 32 can be rotated so that the openings of the spray holes in the part of the spray pipe 32 located in the transparent cover 21 face the blades 221 of the impeller 22, so as to improve the cleaning effect on the blades 221.

[0077] The driving member 33 is connected to the support assembly 10, and the driving member 33 can be directly connected to the liquid storage container 31 and the nozzle 32 or connected to the liquid storage container 31 and the nozzle 32 through a flexible pipeline, so as to realize the connection between the driving member 33 and the liquid storage container 31 and the nozzle 32, and then control the driving member 33 to drive the cleaning agent to be ejected from the nozzle holes of the nozzle 32 from the liquid storage container 31.

[0078] Thus, the structure of the cleaning assembly 30 composed of the liquid storage container 31, the nozzle 32 and the driving member 33 is simple, which can effectively reduce the assembly difficulty of the comparison display device 100 and facilitate later maintenance and replacement.

[0079] Furthermore, the driving member 33 is a water pump or a steam generator. Among them, when the driving member 33 is selected as a water pump, the operation of the comparison display device 100 for cleaning effect will involve the flow of water. The water pump is responsible for providing sufficient water flow to perform the cleaning of the component to be cleaned 20 by the cleaning assembly 30. The water pump can generate water flow through mechanical or electric power to drive the cleaning process. On the other hand, when the driving member 33 is selected as a steam generator, the comparison display device 100 for cleaning effect will utilize the characteristics of steam for cleaning. The steam generator is responsible for generating steam, which can be achieved by heating water or other liquids. The steam is used for the cleaning of the cleaning assembly 30 to effectively remove dirt through its high temperature and humidity characteristics.

[0080] In some structural forms, the cleaning assembly 30 further includes a rotation driving member (not shown). The rotation driving member is arranged on the light-transmitting cover 21 and is rotationally connected to the nozzle 32 to drive the nozzle holes of the nozzle 32 to perform circular motion along the circumferential direction of the impeller 22. Thus, through the above setting, the position of the nozzle holes can be changed during cleaning, so as to further clean multiple positions of the impeller 22 and improve the cleaning effect. It can be understood that the rotation driving member can directly be the motor 23. When the nozzle 32 is located in the inner cavity 222 formed by multiple blades 221 of the impeller 22, the nozzle 32 can be directly connected to the motor shaft of the motor 23 to realize the rotation of the nozzle 32, and then realize the circular motion of the nozzle holes along the circumferential direction of the impeller 22. Or the rotation driving member can include the motor 23 and a turntable. The turntable is connected to the motor shaft of the motor 23, and the nozzle 32 is connected to the turntable. In this way, the motor shaft drives the turntable to rotate to synchronously drive the nozzle 32 to rotate.

[0081] Optionally, the number of the nozzles 32 can be set to multiple to further increase the output amount of the cleaning agent at the same moment. And multiple nozzles 32 can all be located at the inner cavity 222 configured by multiple blades 221 of the impeller 22. Or multiple nozzles 32 are all arranged on the outer periphery of the impeller 22, so that the installation positions of the multiple nozzles 32 are relatively concentrated, which is convenient for unified installation in the early stage and maintenance in the later stage. Of course, a part of the nozzles 32 can also be arranged in the inner cavity 222, and the other part of the nozzles 32 are arranged at intervals on the outer periphery of the impeller 22. In this way, nozzles 32 are arranged at both the inner cavity 222 and the outer periphery of the impeller 22 to spray the cleaning agent, so as to increase the contact area between the cleaning agent and the impeller 22 and improve the cleaning effect.

[0082] Referring to Figures 3 to 5 , in some structural forms, the light-transmitting cover 21 includes a box body part 211 and a cover body part 212. The box body part 211 is connected to the support assembly 10. The box body part 211 has an accommodation cavity 2111 and an installation opening 2112 communicating with the accommodation cavity 2111. The impeller 22 passes through the installation opening 2112 to be installed in the accommodation cavity 2111. The cover body part 212 is movably connected to the box body part 211 to open or cover the installation opening 2112. Among them, the form of the movable connection can be a rotational connection, a pulling connection or a magnetic attraction connection, etc., and the present application does not limit this. In the state where the cover body part 212 covers the installation opening 2112, it can prevent the hands of users or maintenance personnel from directly touching the impeller 22 through the installation opening 2112 during the rotation of the impeller 22, improving the safety of use. At the same time, the cover body part 212 can also block most sundries and prevent them from entering the box body part 211, improving the cleaning effect. In the state where the cover body part 212 opens the installation opening 2112, it is convenient to directly remove the impeller 22 from the installation opening 2112, so as to facilitate spraying oil on the blades 221 of the impeller 22 and repairing the impeller 22.

[0083] Furthermore, the cover body part 212 is provided with air guiding holes 2121. When the cover body part 212 covers the installation opening 2112, the air guiding holes 2121 communicate with the accommodation cavity 2111. In this way, when the impeller 22 rotates, external air flow can enter the accommodation cavity 2111 through the air guiding holes 2121 to maintain the air pressure stability in the accommodation cavity 2111, keep the rotation stability of the impeller 22, reduce the shaking, and further ensure the cleaning effect.

[0084] Referring to Figures 3 to 5, in some structural forms, the support component 10 includes a base 11 and a sewage tank 12. The light-transmitting cover 21 is connected above the base 11. The base 11 can be made of a metal material, so that the base 11 has advantages such as high strength and excellent corrosion resistance, thereby improving the support and stability of the entire structure. The sewage tank 12 is provided at the bottom or inside of the base 11. Such a setting helps to accommodate and collect the sewage generated during the cleaning process. The bottom of the light-transmitting cover 21 is provided with a water outlet hole, and the water outlet hole communicates with the sewage tank 12 to ensure that the cleaning sewage is effectively collected into the sewage tank 12 during the cleaning process. By providing the sewage tank 12 to collect the cleaning sewage, it is possible to prevent the cleaning sewage from spreading and keep the working environment clean. Generally speaking, this structural form realizes the effective collection and management of the cleaning sewage through the reasonable design of the base 11, the light-transmitting cover 21 and the sewage tank 12, and at the same time keeps the working area clean. Such a design can improve the practicality of the equipment and the convenience of operation.

[0085] Furthermore, a fixing groove 111 is recessed on the upper surface of the base 11, and the light-transmitting cover 21 is embedded in the fixing groove 111. In this way, a fixed area is provided by the fixing groove 111 to accommodate the light-transmitting cover 21 and ensure that the light-transmitting cover 21 is firmly embedded on the base 11. This design ensures the firm connection between the light-transmitting cover 21 and the base 11 and prevents accidental detachment or movement. It should be noted that other grooves can also be provided on the upper surface of the base 11 for fixing the liquid storage container 31.

[0086] Optionally, a pulling port 112 is provided on the side wall of the base 11, and the sewage tank 12 is slidably connected to the base 11 to be disassembled and assembled relative to the bottom of the base 11 through the pulling port 112. In this way, the sewage tank 12 is connected to the base 11 by a sliding connection. This connection method allows the user to easily disassemble and install the sewage tank 12 relative to the bottom of the base 11 through the pulling port 112 of the base 11, so as to facilitate the cleaning of the cleaning sewage in the sewage tank 12. This design improves the usability and maintainability of the entire structure.

[0087] Refer to Figures 2 to 4, in some structural forms, the comparison display device 100 further includes a sound insulation protective cover 50. The sound insulation protective cover 50 is detachably connected to the upper surface of the support assembly 10 and covers the component to be cleaned 30 and the components of the cleaning component 30 located on the upper surface of the support assembly 10. In this way, the sound insulation protective cover 50 provides sound insulation protection to reduce the working noise of the comparison display device 100. At the same time, it can also protect the component to be cleaned 30 and the components of the cleaning component 30 located on the upper surface of the support assembly 10 from dust, dirt or other factors that may affect their functions, such as collisions. Thus, external interference is prevented from affecting the comparison display effect. The sound insulation protective cover 50 is designed to be detachably connected to the upper surface of the support assembly 10. This means that the user can easily connect or detach the sound insulation protective cover 50, which may be very convenient for maintenance, cleaning or component replacement.

[0088] Refer to Figures 5 to 6 , in some structural forms, the comparison display device 100 further includes at least two sets of control systems 40. One control system 40 is electrically connected to a component to be cleaned 20 and a cleaning component 30 correspondingly for controlling the impeller 22 of the component to be cleaned 20 and the cleaning component 30 to operate based on cleaning parameters. In this way, through a set of component to be cleaned 20 and a set of cleaning component 30 being uniformly controlled by a single control system 40, the coordinated control of the component to be cleaned 20 and the cleaning component 30 is achieved, enabling them to cooperate more effectively and improving the performance and efficiency of the entire comparison display device 100. The control system 40 includes a power supply board 42 and a control board 41 that are electrically connected. The power supply board 42 can be electrically connected to the motor 23 of the component to be cleaned 20 and the driving member 33 of the cleaning component 30. In this way, by controlling the power supply board 42 to supply power to the motor 23 and the driving member 33 through the control board 41, the operation control of the motor 23 and the driving member 33 is achieved. It should be noted that a cleaning component can be provided with multiple liquid storage boxes. The multiple liquid storage boxes can be used to load different cleaning agents. At the same time, the cleaning component can also be provided with multiple driving members 33. One driving member 33 communicates with one liquid storage box correspondingly. Refer to Figure 7 , in this way, the control board 41 of the control system 40 can control the power supply board 42 to separately supply power to each driving member 33 to achieve the separate operation control of the multiple driving members 33, so that different cleaning agents can be selected for cleaning.

[0089] The above are some optional implementation manners of the comparison display device for the cleaning effect proposed in this application. Combining the above structural forms, the following clarifies the operation logic of the comparison display device of this application based on the comparison display method for the cleaning effect proposed in another aspect of the embodiments of this application.

[0090] Refer to Figure 8 , the comparison display method includes the following steps:

[0091] Step S10: Obtain the cleaning parameters of different cleaning components. Different cleaning components have different cleaning parameters respectively, and the light-transmitting cover and impeller of the component to be cleaned are both coated with oil stains.

[0092] Specifically, the goal of this step is to collect the cleaning parameters of different cleaning components to provide guidance for the subsequent cleaning process. Each cleaning component has different cleaning parameters respectively. These parameters may include but are not limited to the type of cleaning agent, the dosage of cleaning agent, the cleaning duration, as well as the rotation direction, rotation speed, and rotation duration of the impeller, etc. The differences in cleaning parameters can lead to different cleaning effects on the component to be cleaned. And the impeller of the light-transmitting cover of each component to be cleaned is coated with oil stains, which can be real cooking oil stains or other oil stains, so as to clearly observe the situation of the oil stains adhering to the inner wall surfaces of the impeller and the transparent cover after cleaning in the subsequent process.

[0093] Step S20: Control the cleaning components to clean the light-transmitting cover and impeller of the corresponding component to be cleaned according to the corresponding cleaning parameters, so as to achieve different cleaning effects on different components to be cleaned, and display the comparison of different cleaning effects through the light-transmitting covers of different groups of components to be cleaned and the impellers of different groups of components to be cleaned.

[0094] In this way, an adjustable cleaning process is introduced, so as to be able to visually display the cleaning comparison under different cleaning parameters and achieve a comparative display of cleaning effects.

[0095] Refer to Figure 9 , in some structural forms, at least two groups of components to be cleaned include a first component to be cleaned and a second component to be cleaned, at least two groups of cleaning components include a first cleaning component and a second cleaning component, the cleaning parameter includes the type of cleaning agent, and the type of cleaning agent includes water and detergent. The cleaning agent added in the first cleaning component is water, and the cleaning agent added in the second cleaning component is water and detergent.

[0096] In this way, through the above settings, the cleaning effects of only cleaning with clean water and the combined cleaning of clean water and detergent can be compared.

[0097] Step S21: For the first component to be cleaned and the first cleaning component, the steps of controlling the cleaning component to clean the light-transmitting cover and impeller of the corresponding component to be cleaned according to the corresponding cleaning parameters are as follows:

[0098] Step S211: Control the first cleaning component to spray water on the impeller of the first component to be cleaned within the time period T1 and stop spraying the water after the time period T1, and control the impeller of the first component to be cleaned to rotate within the time period T1 + T1' and stop driving the impeller after the time period T1 + T1'.

[0099] In this way, within the time period T1, the first cleaning component sprays water flow onto the impeller of the first component to be cleaned to wash the attached oil stains. At the same time, the impeller is synchronously driven to rotate so that multiple blades of the impeller can be washed by the water flow, ensuring the cleaning area. Meanwhile, the rotation of the impeller can also splash the water flow onto the transparent cover to wash the oil stains on the transparent cover. After the end of the time period T1, the first cleaning component stops spraying water flow. At this time, the impeller of the first component to be cleaned is controlled to rotate within the time period T1' to drain the water and reduce the water residue on the impeller, so as to clearly show the cleaning effect of the impeller and the transparent cover of the first component to be cleaned after cleaning.

[0100] Step S22: For the second component to be cleaned and the second cleaning component, the steps of controlling the cleaning component to clean the light-transmitting cover and the impeller of the corresponding component to be cleaned according to the corresponding cleaning parameters are as follows:

[0101] Step S221: Control the impeller of the second component to be cleaned to rotate within the time period T2 and stop driving the impeller after the time period T2.

[0102] In this way, by making the impeller of the second component to be cleaned rotate within the time period T2 and then stop driving, the impeller generates a self-rotation force, which can not only maintain the rotation of the impeller so that the subsequent sprayed detergent can be sprayed to multiple positions of the impeller. At the same time, it effectively avoids the too fast rotation speed of the impeller, so that when the detergent is sprayed subsequently, the stability of the detergent on the impeller is improved, so that the detergent can fully react with the oil stains and facilitate the detachment of the oil stains.

[0103] Step S222: Control the second cleaning component to spray detergent onto the impeller of the second component to be cleaned within the time period T3 and stop spraying detergent after the time period T3.

[0104] The detergent can be a solution of various cleaning chemicals, etc. Since the impeller has a self-rotation force, part of the detergent can be splashed onto the transparent cover by the impeller to wash the oil stains on the transparent cover by reacting with the detergent. Of course, the second cleaning component can also directly spray the detergent onto the inner wall surface of the transparent cover.

[0105] Step S223: Control the second cleaning component to spray water onto the impeller of the second component to be cleaned within the time period T4 and stop spraying water after the time period T4, and control the impeller of the second component to be cleaned to rotate within the time period T4 + T4' and stop driving the impeller after the time period T4 + T4'.

[0106] After stopping the injection of the detergent, the second cleaning component sprays water flow on the impeller of the second component to be cleaned within the time period T4 for cleaning. At the same time, the impeller is synchronously driven to rotate so that multiple blades of the impeller can all be cleaned by the water flow, ensuring the cleaning area. At the same time, the water flow can be splashed onto the transparent cover through the rotation of the impeller to clean the oil stains on the transparent cover. After the end of the time period T4, the second cleaning component stops spraying water flow. At this time, the impeller of the second component to be cleaned is controlled to rotate within the time period T4' to drain the water and reduce the water residue on the impeller.

[0107] Step S224: Control the second cleaning component to spray the detergent on the impeller of the second component to be cleaned within the time period T5 and stop spraying the detergent after the time period T5.

[0108] In this way, after stopping the water injection, the second cleaning component sprays the detergent on the impeller again for cleaning to react again with the oil stains that have not been cleaned on the impeller and the transparent cover, thereby improving the cleaning effect.

[0109] Step S225: Control the impeller of the second component to be cleaned to rotate within the time period T6 and stop driving the impeller after the time period T6.

[0110] At this time, the impeller of the second component to be cleaned is controlled to rotate within the time period T6 to drain the water and reduce the water residue on the impeller, so as to clearly show the cleaning effect of the impeller and the transparent cover of the second component to be cleaned after cleaning.

[0111] Through the above steps, this method can show the cleaning effects under different cleaning parameters and provide a comparative display, especially the effect comparison when using different types of cleaning agents. The entire process involves multiple cleanings and water draining of the impeller and the light-transmitting cover to ensure that the observer can clearly see the cleaning effect.
