[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] In combination with Figures 1 to 3The embodiment of the present application provides the range hood 1. The range hood 1 comprises a rack 10, a smoke collecting assembly 20 and a joint assembly 30. The smoke collecting assembly 20 is installed on the rack 10. The smoke collecting assembly 20 is connected with the rack 10. The range hood 1 can be installed on a wall through the rack 10 or the smoke collecting assembly 20. The rack 10 is provided with an air outlet (not shown in the figure), and the air outlet can be connected with an external flue through a pipeline. The rack 10 comprises an outer shell, a volute (not shown in the figure) arranged in the outer shell and a centrifugal fan wheel (not shown in the figure) arranged in the volute. The volute can be in communication with the inside of the smoke collecting assembly 20, and the negative pressure generated by the rotation of the centrifugal fan wheel can drive the gas in the smoke collecting assembly 20 to the air outlet for exhaust. The front side of the smoke collecting assembly 20 is provided with a main air inlet (the range hood 1 is in a closed state in the figure, and the main air inlet is blocked), and the main air inlet is arranged correspondingly to a cooking appliance. The main air inlet can suck the oil fume generated in the cooking process, and then exhaust the oil fume through the smoke collecting assembly 20 and the rack 10.

[0024] The range hood 1 of the present application further comprises a steam generating system, and the steam generating system is a core component for realizing the steam cleaning function. The steam generating system mainly comprises a steam generator and a liquid pump. The steam generator can quickly heat water to a preset high temperature state through a built-in high-efficiency heating element, so as to generate high-temperature steam. The high-temperature steam has cleaning ability and can effectively dissolve and remove oil stains and incrustations in the range hood 1. The joint part 31 of the joint assembly 30 is connected with the liquid pump, and the liquid pump is responsible for conveying water from an external water source pipeline to the steam generator. The liquid pump can ensure that the steam generator continuously obtains stable water supply, so as to guarantee the continuous generation and stable output of steam.

[0025] The range hood 1 further comprises a spray head, and the spray head can spray high-temperature steam to key parts such as the centrifugal fan wheel, an oil screen and a volute. These parts are prone to accumulate oil stains in the long-term operation of the range hood 1, and the spraying of high-temperature steam can quickly soften and decompose these stubborn stains, so as to realize deep cleaning of the inside of the range hood 1.

[0026] In traditional range hood 1 designs, the connection to the water supply pipe is usually located on the side of the range hood 1. However, this design has significant limitations in practical use. When the range hood 1 is installed in a kitchen, the side often abuts a wall or a wall cabinet, which greatly limits the operating space, making it difficult for the user to connect the water supply pipe. For example, the narrow space can make it difficult for the user to operate accurately, increasing the difficulty and time of installation, and even possibly damaging the pipe or connector due to improper operation. To improve this technical problem, the connector assembly 30 of the present application is installed on the side of the smoke collection assembly 20 away from the rack 10, and the connector assembly 30 includes a connector part 31 for connecting the pipe, and the connector part 31 faces the front side of the range hood 1. By setting the connector part 31 of the connector assembly 30 to face the front side of the range hood 1, the space on the front side of the range hood 1 is fully utilized, as the front side is usually not obstructed by a wall cabinet or wall, thereby providing a more spacious operating space for the user. In this way, the user can more easily access the connector when connecting the water supply pipe, without having to perform complex operations in a narrow side space. This design not only simplifies the installation process, but also improves installation efficiency and reliability. In addition, due to the increased operating space, the user can more accurately align the connector part 31 when connecting the pipe, reducing the risk of water leakage or loose connection, thereby improving the user experience of the steam cleaning of the range hood 1.

[0027] During the daily operation of the range hood 1, oil fumes passing through the smoke collection assembly 20 and the rack 10 will condense due to the decrease in temperature, forming oil droplets. In addition, during steam cleaning, high-temperature steam will also condense when it encounters cooler components, forming water droplets. If these droplets fall directly, they can contaminate the surface of the cooking table, or even splash around, causing inconvenience to the kitchen environment.

[0028] To solve this problem, the range hood 1 of the present application also includes an oil cup 40, which is installed on the smoke collection assembly 20. The oil cup 40 can effectively collect these condensate oil droplets and water droplets, preventing them from falling directly on the cooking table or elsewhere, thereby maintaining the cleanliness of the kitchen. In addition, it can be easily removed from the smoke collection assembly 20 for the user to regularly clean the oil and water accumulated therein. This design not only reduces the accumulation of oil inside the range hood 1, prolonging the service life of the range hood 1, but also improves the user experience, making the kitchen environment cleaner and more hygienic.

[0029] In some embodiments, the oil cup 40 is installed on the side of the smoke collection assembly 20 away from the rack 10, and the joint assembly 30 divides the oil cup 40 into two parts, with the two parts of the oil cup 40 located on the two sides of the joint assembly 30. In this way, on the one hand, by dividing the oil cup 40 into two parts, the space originally used to connect the oil cup 40 is redistributed, providing enough space for the installation of the joint assembly 30 under the smoke collection assembly 20. In this way, the installation of the joint assembly 30 does not occupy too much additional space, thereby avoiding negative effects on the overall appearance and structural design of the range hood 1. This design makes the joint assembly 30 almost integrated with the range hood 1 after installation, reducing the protruding part of the joint assembly 30, and further improving the aesthetic appearance of the range hood 1 after installation. On the other hand, in addition to connecting with the water source pipeline, the joint assembly 30 can also serve to install and position the oil cup 40. During the operation of the range hood 1, the oil cup 40 needs to withstand a certain weight and vibration, and the positioning function of the joint assembly 30 can effectively prevent the oil cup 40 from shifting or loosening under the action of these external forces, thereby ensuring that the oil cup 40 can stably collect condensate droplets and avoid leakage of oil stains and water droplets. Moreover, after the oil cup 40 is divided into two parts, the length of each part is reduced, which facilitates the disassembly and installation of the oil cup 40.

[0030] In some embodiments, the joint assembly 30 is installed in the middle of the smoke collection assembly 20. By placing the joint assembly 30 in the middle of the smoke collection assembly 20, the two parts of the oil cup 40 can be designed to be quite long, or even symmetrically distributed. This symmetry not only meets the aesthetic needs of modern kitchen design, but also makes the overall appearance of the range hood 1 more concise and harmonious, improving the visual aesthetics of the product. Moreover, since the two parts of the oil cup 40 are of equal length and symmetrically distributed, they can accommodate almost the same amount of liquid after installation. This means that the two parts of the oil cup 40 have more balanced capacity utilization when collecting condensate droplets and water droplets. Therefore, users do not need to frequently check and clean the two oil cups 40 during use, but can clean and maintain both parts according to a unified time interval. This design greatly simplifies the user's daily maintenance process, reduces the user's usage burden, and improves the ease of use of the product.

[0031] In combination Figures 4 to 6Specifically, in some embodiments, the joint assembly 30 further comprises a mounting portion 32, and the oil cup 40 is mounted to the smoke collection assembly 20 at least through the mounting portion 32. The mounting portion 32 can be provided with a mounting groove (not shown in the figure), and one end of the oil cup 40 close to the joint assembly 30 is detachably mounted to the mounting groove. The oil cup 40 can be detached from the mounting portion 32. This design facilitates the user to clean the oil stains and condensed water in the oil cup 40, not only improves the user experience, but also enhances the stability and reliability of the installation of the oil cup 40. The oil cup 40 can be easily detached from the mounting portion 32, which is convenient for the user to clean regularly, ensures that the inside of the range hood 1 remains clean, and prolongs the service life.

[0032] Further, the range hood 1 further comprises mounting supports 60, which are fixedly mounted to the side of the smoke collection assembly 20 away from the rack 10, and the mounting supports 60 are arranged in a spaced manner with the joint assembly 30. The number of mounting supports 60 can be designed according to actual needs, which can be one, two or more, and the specific number is not strictly limited. Taking the case that two mounting supports 60 are provided as an example, the mounting supports 60 can be arranged on both sides of the joint assembly 30 to form a symmetrical layout. This layout not only looks beautiful, but also can further enhance the installation stability of the oil cup 40. The mounting supports 60 can achieve the installation of the oil cup 40 at the end away from the joint assembly 30, while the mounting portion 32 can achieve the installation of the oil cup 40 at the end close to the joint assembly 30. Through the cooperation of the mounting supports 60 and the mounting portion 32, the stable installation of the two parts of the oil cup 40 can be achieved, which ensures that the oil cup 40 will not loosen or shift during the operation of the range hood 1, thereby effectively avoiding the leakage of oil stains and condensed water, and improving the overall performance and user experience of the range hood 1.

[0033] In some embodiments, the surface of the mounting portion 32 facing the front side of the range hood 1 is closer to the smoke collection assembly 20 than the surface of the joint portion 31 facing the front side of the range hood 1. In the above manner, a limiting surface can be formed on the side of the joint portion 31 facing the oil cup 40, and the end of the oil cup 40 can abut against the limiting surface. The surface of the mounting portion 32 facing the front side of the range hood 1 is designed to be closer to the smoke collection assembly 20 than the surface of the joint portion 31 facing the front side of the range hood 1. This structural design naturally forms a limiting surface on the side of the joint portion 31 facing the oil cup 40, and the end of the oil cup 40 can abut against the limiting surface. Through the above manner, on the one hand, the movement of the oil cup 40 can be limited by the limiting surface, increasing the stability of the installation of the oil cup 40. On the other hand, the inward approach of the surface of the mounting portion 32 can also form a space for accommodating the oil cup 40, so that the side wall of the oil cup 40 can be accommodated by the stepped structure formed by the mounting portion 32 and the joint portion 31, which is conducive to the matching of the shape of the oil cup 40 and the shape of the joint assembly 30. Optionally, other surfaces of the mounting portion 32 except the surface facing the smoke collection assembly 20 are closer to the smoke collection assembly 20 than other surfaces of the joint portion 31 except the surface facing the smoke collection assembly 20.

[0034] Specifically, in some embodiments, the edge of the oil cup 40 away from the hood assembly 20 coincides with the projection of the edge of the joint assembly 30 away from the hood assembly 20 in the length direction of the oil cup 40. This means that the outer edge of the oil cup 40 is flush with the outer edge of the joint assembly 30 when viewed from the outside, forming an overall appearance. In other words, the outer surface of the mounting portion 32 (except the surface facing the hood assembly 20) is designed to be consistent with the wall thickness of the oil cup 40 in terms of the dimension closer to the hood assembly 20 than the outer surface of the joint portion 31. This design ensures that the wall thickness of the oil cup 40 matches the dimension of the limiting surface in the wall thickness direction of the oil cup 40. Therefore, when the oil cup 40 is installed in place, its outer edge can be aligned with the outer edge of the joint assembly 30, forming a flat surface. In this way, it is beneficial to improve the aesthetic level of the extractor hood 1 and can also reduce the interference between the joint assembly 30 and the oil cup 40 and other components. Optionally, the shape of the oil cup 40 is shaped to match the shape of the mounting portion 32. This means that the outer shape of the oil cup 40 forms a more natural transition with the outer shape of the mounting portion 32. This shaped design not only enhances the overall feeling of the extractor hood 1, but also makes the cooperation between the oil cup 40 and the joint assembly 30 more compact, further reducing potential problems caused by shape mismatch.

[0035] In some embodiments, the joint assembly 30 further comprises a movably arranged end cover 50 provided with a protrusion 51 matching the joint portion 31 to open or close the joint portion 31. The end cover 50 can be movably connected with the joint portion 31, or movably connected with the mounting portion 32, or movably connected with the hood assembly 20, which is not specifically limited here. When the extractor hood 1 is normally working and not performing steam cleaning, the end cover 50 can close the joint portion 31. This closed state not only prevents dust, debris or other foreign matter from entering the joint portion 31, but also makes the appearance of the extractor hood 1 more neat and beautiful, improving the overall visual effect of the product. The closed end cover 50 forms a smooth surface with other components of the extractor hood 1, further enhancing the aesthetic appearance of the extractor hood 1. When steam cleaning is needed, the end cover 50 can be opened to expose the joint portion 31. At this time, the user can conveniently connect the water source pipeline to the joint portion 31 to provide water source for the steam generating system.

[0036] In some embodiments, the surface of the joint portion 31 facing the front side of the extractor hood 1 is closer to the hood assembly 20 than the surface of the mounting portion 32 facing the front side of the extractor hood 1. The end cover 50 can be accommodated in the space formed by the joint portion 31 and the mounting portion 32. Optionally, when the end cover 50 is closed, the surface of the mounting portion 32 facing the front side of the extractor hood 1 is closer to the hood assembly 20 than the surface of the end cover 50 facing the front side of the extractor hood 1, thereby forming the aforementioned limiting surface on the end cover 50. The limiting surface formed by the end cover 50 and the mounting portion 32 can achieve the same technical effects as the limiting surface formed by the aforementioned mounting portion 32 and joint portion 31, which will not be repeated here.

[0037] In some embodiments, the hardness of the protruding portion 51 is greater than the hardness of the joint portion 31. The joint portion 31 can be made of a flexible material, such as rubber or silicone, etc. The flexible joint portion 31 can facilitate insertion into the water source pipe while maintaining good sealing performance. The protruding portion 51 can be made of a hard material, such as plastic or metal, etc. The hardness of the protruding portion 51 being greater than the hardness of the joint portion 31 can facilitate the plug-in fit of the protruding portion 51 and the joint portion 31 when the end cover 50 is closed.

[0038] In combination Figure 7 During operation of the range hood 1, liquid droplets formed by condensation of oil fumes or steam can form on the inner surface of the smoke collection assembly 20 and drop. Without proper guidance, these liquid droplets can flow randomly within the smoke collection assembly 20, or even stay in unintended positions due to surface tension, causing oil accumulation or liquid leakage. In some embodiments, the joint assembly 30 is disposed near the surface of the smoke collection assembly 20, inclined away from the smoke collection assembly 20 in the direction towards the oil cup 40. In this way, the flow of liquid droplets in the smoke collection assembly 20 towards the oil cup 40 can be facilitated, and the flow of liquid droplets can be guided.

[0039] In some embodiments, the joint assembly 30 further includes an indicator light that visually displays different working stages and states of the range hood 1 through different colors and flashing frequencies. This design allows the user to quickly understand the operation of the range hood 1 without additional operation or inspection. For example, the range hood 1 works with constant white light, the range hood 1 works for a period of time to accumulate a reminder to clean with bright red light, the start of the cleaning process with red breathing mode flashing, and white breathing mode flashing after cleaning is completed.

[0040] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
