[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0024] In combination Figure 1 The present application provides a range hood 10. The core component of the range hood 10 is a smoke collection assembly 100, which is provided with a main air inlet 101 on the front side, and the main air inlet 101 is arranged corresponding to the cooking appliance, which can effectively adsorb the oil fume generated during cooking. The range hood 10 includes a volute (not shown in the figure) and a centrifugal fan (not shown in the figure), and the centrifugal fan is arranged in the volute. In some embodiments, the volute and the centrifugal fan can be installed in the smoke collection assembly 100. The volute and the centrifugal fan can cooperate to generate negative pressure, thereby driving the convection of the gas and discharging the oil fume from the main air inlet 101 to the air outlet 102. Optionally, the air outlet 102 can be provided with an air outlet cover or a check valve, and then connected to the flue through a pipeline such as a corrugated pipe to ensure smooth discharge of the oil fume.

[0025] In other embodiments, the design structure of the range hood 10 includes a rack (not shown in the figure) and the smoke collection assembly 100. The smoke collection assembly 100 is mounted on the rack and firmly connected with the rack. The range hood 10 can be fixed to the wall through the rack or the smoke collection assembly 100, thereby achieving a stable installation effect. The rack is arranged corresponding to the air outlet 102 on the smoke collection assembly 100, so that the gas in the smoke collection assembly 100 can flow smoothly into the inside of the rack from the air outlet 102. The rack is also provided with a smoke exhaust port, which can be provided with an air outlet cover or a check valve as needed, and connected to the external flue through a pipeline such as a corrugated pipe to ensure that the oil fume can be discharged smoothly. The rack includes a housing, and the volute and the centrifugal fan are arranged in the rack. The volute can be in communication with the inside of the smoke collection assembly 100. When the centrifugal fan rotates, negative pressure can be generated, thereby driving the gas in the smoke collection assembly 100 to the smoke exhaust port for discharge. The front side of the smoke collection assembly 100 is provided with the main air inlet 101, which is arranged corresponding to the cooking appliance, and the main air inlet 101 can suck the oil fume generated during cooking, and then discharge the oil fume through the air outlet 102 after passing through the smoke collection assembly 100 and the rack.

[0026] In combination Figure 1 and Figure 2In some embodiments, the smoke collection assembly 100 comprises a back plate and a panel assembly 10, and the back plate is spaced apart from the panel assembly 10. The space between the back plate and the panel assembly 10 can form a smoke collection cavity, through which the smoke can be discharged. The side of the panel assembly 10 facing the user has display and / or control functions. The user can control the range hood 10 through the panel assembly 10. Specific embodiments of the panel assembly 10 can be described below.

[0027] In combination Figures 2 to 5 , the panel assembly 10 is provided. The panel assembly 10 comprises a front plate 11, a backing plate 12 and a control housing 13. The backing plate 12 is mounted on the front plate 11. The control housing 13 is mounted on the front plate 11, and the backing plate 12 and the control housing 13 are mounted on the same side of the front plate 11. The backing plate 12 has a spacing portion 121, which is located on at least one side of the control housing 13. The spacing portion 121 is spaced apart from the front plate 11 and forms an accommodation space, and the control housing 13 is at least partially located in the accommodation space. The spacing portion 121 covers at least part of the gap between the control housing 13 and the front plate 11. By providing the spacing portion 121 and the front plate 11 to form the accommodation space, at least part of the control housing 13 can be accommodated. In the accommodation space, the gap between the control housing 13 and the front plate 11 can be directly blocked by the spacing portion 121, thereby reducing the possibility of liquid droplets entering the control housing 13 from the gap between the front plate 11 and the control housing 13, and reducing the impact of liquid droplets on the components in the control housing 13. It should be noted that the circumferential direction of the control housing 13 forms a gap with the front plate 11, and the spacing portion 121 is arranged on at least one side of the circumferential direction of the control housing 13 corresponding to the gap formed by the front plate 11.

[0028] In some embodiments, the panel assembly 10 further comprises a control assembly 20 (in combination Figure 3 , the control housing 13 and the front plate 11 form a mounting space by surrounding, and the control assembly 20 is mounted in the mounting space. This layout not only provides a stable mounting position for the control assembly 20, but also effectively prevents liquid from entering the mounting space through the design of the spacing portion 121, thereby further improving the waterproof and oil-proof performance and reliability of the panel assembly 10. The specific type of the control assembly 20 can be selected according to actual needs, for example, it can be a piano key switch, a micro switch, etc., which is not limited in particular.

[0029] In some embodiments, in combination Figure 3 and Figure 6The panel assembly 10 further comprises a control front cover 14 arranged in the mounting space, a control assembly 20 arranged between the control front cover 14 and the control housing 13, and the control housing 13 cooperates with the control front cover 14 to mount the control assembly 20 to the front plate 11. The control front cover 14 and the control housing 13 cooperates to fix or encapsulate the control assembly 20. The control assembly 20 can be stably mounted to the front plate 11 by the control housing 13 and the control front cover 13.

[0030] Further, the control housing 13 comprises a body portion 131 comprising a bottom wall 1311 and a side wall 1312 extending from the outer edge of the bottom wall 1311 towards the front plate 11, the bottom wall 1311 is arranged spaced apart from the front plate 11, and the end of the side wall 1312 close to the front plate 11 abuts against the front plate 11. In this way, the control housing 13 can not only fix the control assembly 20, but also reduce the possibility of liquid droplets entering the mounting space by the abutment of the side wall 1312 and the front plate 11. Optionally, an extension portion 132 extends from one of the side walls 1312 away from the bottom wall 1311 along the plane of the front plate 11. The spacing portion 121 can cover the gap between the extension portion 132 and the front plate 11, and also cover the gap between the side wall 1312 and the front plate 11, thereby further reducing the possibility of liquid droplets entering the control housing 13.

[0031] In some embodiments, the spacing portion 121 of the panel assembly 10 is arranged at least on the side of the control housing 13 close to the air outlet 102 of the smoke collection assembly 100. After installation, the smoke machine 10 will condense liquid droplets in the interior of the smoke machine 10, and the liquid droplets will fall downward under the action of gravity. In other words, the main cause of the liquid entering the control housing 13 in the interior of the smoke machine 10 is the liquid droplets falling from top to bottom. The side of the smoke collection assembly 100 with the air outlet 102 is generally arranged upward. By arranging the spacing portion 121 on the side of the control housing 13 close to the air outlet 102 of the smoke collection assembly 100, the spacing portion 121 can block the upward gap between the control housing 13 and the front plate 11. In this way, the possibility of liquid droplets falling from top to bottom under the action of gravity entering the control housing 13 from the gap is reduced.

[0032] In some embodiments, the spacer 121 abuts against a side of the control housing 13 distal to the front plate 11. This abutment design can significantly increase the path length required for a liquid droplet to enter the control housing 13 from the outside. By lengthening the entry path of the liquid droplet, the spacer 121 not only sets up a physical barrier for the liquid droplet to enter the control housing 13, but also increases the resistance that the liquid droplet needs to overcome during the entry process. This design makes the liquid droplet need to go through more tortuous paths before entering the control housing 13, thus greatly reducing the possibility of the liquid droplet entering the inside of the control housing 13. Even if a small amount of liquid droplet contacts the surface of the spacer 121 or the control housing 13, due to the lengthening and tortuosity of the path, these liquid droplets are more likely to slide along the outer surface under the action of gravity rather than enter the inside of the control housing 13.

[0033] In some embodiments, the control housing 13 has a body portion 131 and an extension portion 132 extending from the body portion 131 towards the direction close to the spacer 121. The extension portion 132 is located in the accommodation space, and the extension portion 132 and the body portion 131 are integrally formed. On the one hand, the provision of the extension portion 132 can significantly increase the length of the gap between the front plate 11 and the control housing 13. In this way, the path required for a liquid droplet to enter the control housing 13 from the outside is lengthened, increasing the difficulty of the liquid droplet entering the control housing 13. This design takes advantage of the lengthening of the physical path, making it more likely for the liquid droplet to slide due to gravity during the entry process rather than enter the inside of the control housing 13. This improvement effectively reduces the possibility of the liquid droplet entering the inside of the control housing 13, thus reducing the risk of short circuit or corrosion caused by the liquid droplet. On the other hand, the extension portion 132 can change the position of the gap entrance between the control housing 13 and the front plate 11. By adjusting the position of the gap, the extension portion 132 can better match the position of the spacer 121, thus achieving a more efficient sealing effect, making it difficult for the liquid droplet to enter the inside of the control housing 13 even if it contacts the gap. The integrally formed extension portion 132 and body portion 131 can make there be no gap between the extension portion 132 and the body portion 131, further reducing the risk of the liquid droplet entering the inside of the control housing 13.

[0034] In some embodiments, the thickness of the body portion 131 is greater than the thickness of the extension portion 132 in the direction perpendicular to the plane on which the front plate 11 lies. The body portion 131 has a greater thickness, which enables sufficient mounting space to be provided between the body portion 131 and the front plate 11. The greater thickness of the body portion 131 not only provides the necessary space for the control assembly 20, but also provides better protection for the control assembly 20, reducing the impact of external impact or vibration on the internal elements. In addition, the greater thickness also helps to improve the overall structural strength of the control housing 13, ensuring its stability and reliability during long-term use. In comparison with the body portion 131, the extension portion 132 has a smaller thickness. In this way, the extension portion 132 fits more closely with the front plate 11, thereby reducing the size of the gap between the two. The smaller gap size is crucial for preventing liquid droplets from entering the interior of the control housing 13. By reducing the gap, it is more difficult for liquid droplets to enter the interior of the control housing 13 through this narrow passage under the action of gravity, thereby further reducing the risk of short circuit or corrosion caused by liquid droplets.

[0035] In some embodiments, the backing plate 12 is provided with a clearance opening 124, and the control housing 13 is mounted to the front plate 11 from the clearance opening 124, and the spacing portion 121 is arranged at one edge of the clearance opening 124. The backing plate 12 is provided with one clearance opening 124, and the control housing 13 is mounted to the front plate 11 through this clearance opening 124. This way provides sufficient mounting space for the control housing 13, ensuring that it can be firmly fixed to the front plate 11, while not affecting the drainage effect of the liquid droplets by other parts of the backing plate 12. The spacing portion 121 is arranged at the edge of the clearance opening 124, which has a small forming difficulty, which is conducive to reducing the manufacturing cost of the backing plate 12. For example, the spacing portion 121 can be formed by simple sheet metal stamping. Alternatively, the spacing portion 121 is arranged at the edge of the clearance opening 124 close to the air outlet 102 of the smoke collection assembly 100. Since the air outlet 102 of the smoke collection assembly 100 is usually arranged upward, liquid droplets are more likely to enter the gap from this side. Arranging the spacing portion 121 at this position can more effectively block the gap and reduce the possibility of liquid droplets entering the interior of the control housing 13,

[0036] In some embodiments, one side of the backing plate 12 is provided with a first oil guide portion 122, which extends obliquely in a direction away from the front plate 11 and towards the control housing 13. The spacing portion 121 and the first oil guide portion 122 are provided on the same side of the control housing 13. The design of the first oil guide portion 122 can effectively guide the liquid droplets falling from above to the inside of the smoke collection assembly 100. Due to the oblique extension structure, the liquid droplets will slide along the inclined surface of the oil guide portion under the action of gravity, and finally be guided into the inside of the smoke collection assembly 100, instead of directly falling on the control housing 13 or the spacing portion 121. This design reduces the possibility of liquid droplets directly contacting the control housing 13 and the spacing portion 121, thereby reducing the risk of liquid droplets entering the inside of the control housing 13. By arranging the spacing portion 121 between the first oil guide portion 122 and the control housing 13, the first oil guide portion 122 not only plays a role in guiding oil, but also provides an additional layer of protection for the control housing 13. This layout makes the liquid droplets first contact the first oil guide portion 122 during the falling process, instead of directly falling on the control housing 13. Even if a small amount of liquid droplets fail to be completely guided by the oil guide portion, they will be further blocked by the spacing portion 121, thereby further reducing the risk of oil entering the inside of the control housing 13.

[0037] Specifically, in the direction of the first oil guide portion 122 towards the control housing 13, the projection of the control housing 13 is at least partially located within the projection of the first oil guide portion 122. By placing the projection part of the control housing 13 within the projection range of the first oil guide portion 122, the first oil guide portion 122 can act like a "roof" to block the liquid droplets falling from above from directly contacting the control housing 13. Even if liquid droplets slide from above, they will first contact the first oil guide portion 122, instead of directly falling on the control housing 13. This design significantly reduces the opportunity for liquid droplets to directly contact the control housing 13, thereby reducing the risk of splashing and entering the inside of the control housing 13. Due to the oblique design of the first oil guide portion 122, the liquid droplets will slide along the inclined surface under the action of gravity, instead of directly impacting the surface of the control housing 13. This design reduces the splashing phenomenon that may occur when the liquid droplets contact the control housing 13.

[0038] In some embodiments, the distance between the end of the first oil guide portion 122 facing away from the front plate 11 and the front plate 11 is greater than the spacing distance between the spacing portion 121 and the front plate 11. By setting the distance between the end of the first oil guide portion 122 and the front plate 11 to be greater than the spacing distance between the spacing portion 121 and the front plate 11, the first oil guide portion 122 can effectively cover the spacing portion 121. In this way, when liquid droplets fall from above, they will first contact the first oil guide portion 122 instead of directly falling on the spacing portion 121. The inclined design of the first oil guide portion 122 can guide the liquid droplets to slide along its surface and eventually be guided into the inside of the smoke extractor assembly 100. This design reduces the possibility of liquid droplets directly contacting the spacing portion 121, thereby further reducing the risk of liquid droplets entering the inside of the control housing 13.

[0039] In some embodiments, a second oil guide portion 123 is provided on the other side of the backing plate 12 opposite the side where the first oil guide portion 122 is located, and the second oil guide portion 123 extends obliquely in a direction away from the front plate 11, i.e., in a direction away from the control housing 13. The backing plate 12 can use the Coanda effect to guide falling liquid droplets, and the second oil guide portion 123 can guide these liquid droplets to slide along its inclined surface and into the inside of the smoke extractor assembly 100 when they fall from above. This drainage design allows liquid droplets to be effectively guided into the inside of the smoke extractor assembly 100 instead of randomly falling on other parts. The provision of the second oil guide portion 123 further reduces the possibility of liquid droplets falling from the main air inlet 101 or other gaps outside the extractor hood 10. This design not only maintains the cleanliness of the inside of the extractor hood 10, but also avoids liquid droplets from falling on the cooktop or other kitchen equipment, thereby reducing the cleaning workload and improving the user experience.

[0040] By providing the first oil guide portion 122 and the second oil guide portion 123 on both sides of the backing plate 12, the extractor hood 10 of the present application achieves optimization in liquid droplet management. The first oil guide portion 122 is mainly responsible for protecting the control housing 13 and the spacing portion 121, reducing the possibility of liquid droplets directly contacting these components; while the second oil guide portion 123 further guides liquid droplets to flow into the inside of the smoke extractor assembly 100, ensuring that liquid droplets can be collected by the oil cup, thereby reducing the pollution of the external environment by liquid droplets. This dual oil guide portion design enhances the oil leakage prevention performance of the extractor hood 10, improving the overall performance and user experience of the product. Through the synergistic effect of the first oil guide portion 122 and the second oil guide portion 123, the extractor hood 10 can more effectively handle condensate droplets during operation, maintain the dryness and cleanliness of internal components, and reduce the pollution of the external environment by liquid droplets, thereby prolonging the service life of the equipment and reducing maintenance costs.

[0041] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
