[0025] 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 part 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 work fall within the scope of protection of the present application.

[0026] In combination with Figure 1 The present application provides a smoke machine 1. The smoke machine 1 comprises a frame 10 and a smoke collecting assembly 20, and the smoke collecting assembly 20 is provided with a smoke collecting port 211. The smoke collecting assembly 20 is installed on the frame 10, and the smoke machine 1 can be installed on a wall or other installation position through the frame 10. The smoke machine 1 has a mounting surface, for example, when the smoke machine 1 is installed on a wall, the surface of the smoke machine 1 abutting against the wall is the mounting surface of the smoke machine 1. The frame 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 frame 10 is further provided with a volute (not shown in the figure), and the volute is provided with a centrifugal fan (not shown in the figure). The volute can be in communication with the inside of the smoke collecting assembly 20, and the convection generated by the rotation of the centrifugal fan can drive the gas in the smoke collecting assembly 20 to the air outlet for discharge.

[0027] The smoke collection assembly 20 is mounted to the machine frame 10, and is capable of collecting smoke and discharging the smoke through the machine frame 10. The smoke collection assembly 20 includes a smoke collection body 21 and a lifting body 22, which is movably mounted to the smoke collection body 21. The lifting body 22 is capable of forming a main air inlet 201 in cooperation with the smoke collection body 21. The smoke machine 1 further includes an opening and closing member 30, which is movably mounted to the smoke collection body 21. The smoke collection body 21 is further provided with a smoke inlet 211, and the opening and closing member 30 is movably mounted to the smoke collection body 21 and is arranged in correspondence with the smoke inlet 211. The lifting body 22 is movable relative to the smoke collection body 21 to open or close the main air inlet 201. The opening and closing member 30 is movable relative to the smoke collection body 21 to open or close the smoke inlet 211. When the opening and closing member 30 is opened, it can also have the technical effect of gathering smoke. The main air inlet 201 and the smoke inlet 211 can cooperate to respectively suck smoke from different positions, so as to improve the smoke suction effect of the smoke machine 1. The lifting body 22 can also improve the aesthetic appearance of the smoke machine 1 when closed by moving to close the main air inlet 201, and the opening and closing member 30 can also improve the aesthetic appearance of the smoke machine 1 when closed by moving to close the smoke inlet 211.

[0028] In some embodiments, in combination Figure 1 The main air inlet 201 and the smoke inlet 211 are oriented in the same direction. For example, the main air inlet 201 and the smoke inlet 211 can both be oriented away from the mounting surface (e.g. a wall) of the smoke machine 1 to suck in smoke. The smoke machine 1 can suck in oil fume from the side of the cooking appliance, leaving space above the cooking appliance. In this way, the main air inlet 201 and the smoke inlet 211 are not too far away from the cooking appliance, reducing the possibility of reducing the smoke suction effect.

[0029] In some embodiments, the smoke machine 1 has a front side and a rear side, and the rear side of the smoke machine 1 can abut against a wall surface or a placement surface. The main air inlet 201 and the smoke inlet 211 are both oriented towards the front side of the smoke machine 1. When the smoke machine 1 is in an open state, the smoke collection body 21 is arranged between the machine frame 10 and the lifting body 22, and the main air inlet 201 is farther away from the machine frame 10 than the smoke inlet 211. In this way, the main air inlet 201 is closer to the cooking appliance, and can quickly suck in most of the oil fume. The smoke inlet 211 is farther away from the cooking appliance than the main air inlet 201, and can suck in oil fume that the main air inlet 201 fails to completely suck in. In this way, oil fume generated during cooking can be sucked in in a zoned manner, improving the smoke suction effect of the smoke machine 1.

[0030] In some embodiments, during the process of opening, the lifting main body 22 moves away from the smoke collection main body 21 to open the main air inlet 201, and the opening and closing member 30 moves away from the air inlet 211 to open the air inlet 211. During the process of closing, the lifting main body 22 moves close to the smoke collection main body 21 to close the main air inlet 201, and the opening and closing member 30 moves close to the air inlet 211 to close the air inlet 211.

[0031] In some embodiments, the smoke collection main body 21 comprises a rear plate and a front plate arranged at intervals and a plurality of side plates connecting the front plate and the rear plate, and the air inlet 211 is arranged on the side of the front plate away from the lifting main body 22, and the lifting main body 22 can be accommodated between the front plate and the rear plate.

[0032] In some embodiments, the front plate, the side plate and the rear plate are arranged to form a rectangular parallelepiped shape of the smoke collection main body 21. The thickness of the side plate in the interval direction of the front plate and the rear plate is maintained at a predetermined value. And / or the smoke machine 1 has a mounting surface parallel to the rear plate and the front plate, and the distance between each part of the front plate and the mounting surface is equal. In other words, the smoke collection main body 21 of the present application has a uniform thickness, thereby reducing the occupation of the cooking space by the smoke collection main body 21. Optionally, the thickness of the rack 10 in the direction away from the mounting surface is greater than the thickness of the smoke collection main body 21 in the direction away from the mounting surface. Optionally, the distance between the front plate and the rear plate is maintained at a predetermined value. It should be noted that the front plate, the rear plate or the side plate will be subjected to sheet metal process during manufacturing for consideration of strength and assembly, resulting in some protrusions or depressions, and the aforementioned distance measurement can take the plane where the largest area of the plate is located as the reference.

[0033] In some embodiments, for the convenience of description, the smoke machine 1 has a first direction, a second direction and a third direction which are orthogonal. The interval direction of the rack 10 and the smoke collection main body 21 is the second direction, the direction towards which the main air inlet 201 and the air inlet 211 (i.e. the direction from the back side to the front side of the smoke machine 1) is the third direction, and the direction perpendicular to the second direction and the third direction is the first direction. Optionally, the axis direction of the opening and closing member 30 relative to the smoke collection main body 21 is parallel to the first direction. In the case that the smoke machine 1 is installed to the wall surface, the second direction can be the direction of gravity, the third direction can be the direction away from the wall surface, and the first direction can be the horizontal direction. Optionally, the air inlets 211 are symmetrically arranged on the smoke collection assembly 20 and are respectively arranged on both sides of the rack 10 in the first direction.

[0034] In combination Figures 2 to 5 In some embodiments, the air inlet 211 is provided with a corresponding air guide member 50, the air guide member 50 is closer to the inside of the smoke collection assembly 20 than the plane where the air inlet 211 is located, the air guide member 50 is arranged at an interval from the edge of the air inlet 211 close to the rack 10, and an air inlet passage 501 is formed therearound. Optionally, no holes are arranged on the air guide member 50.

[0035] Combining Figure 8 And Figure 9 , Figure 8 The flow direction of the oil droplets in the hood 1 is shown in FIG. 11. By arranging the air guide 50 close to the inside of the smoke collecting assembly 20 at the air collecting opening 211, on the one hand, the air guide 50 can guide the airflow entering the air collecting opening 211, so that the flue gas can be more easily discharged towards the direction of the rack 10. On the other hand, the oil droplets generated by the flue gas entering the air collecting opening 211 can accumulate on the air guide 50, and the air guide 50 located inside the smoke collecting assembly 20 can guide the oil droplets to the inside of the smoke collecting assembly 20, thereby improving the technical problem of oil dripping in the hood 1. Figure 9 In some embodiments, the air guide 50 is arranged to be inclined towards the inside of the smoke collecting assembly 20 in the direction close to the rack 10. Specifically, the edge of the air guide 50 close to the rack 10 is closer to the inside of the smoke collecting assembly 20 than the edge away from the rack 10. On the one hand, the inclined arrangement of the air guide 50 can guide the gas entering from the air collecting opening 211, specifically, guide the airflow in the direction close to the rack 10. On the other hand, the inclined arrangement of the air guide 50 can make the oil droplets accumulated on the air guide 50 slide along the surface of the air guide 50, thereby reducing the possibility of oil droplets staying on the air guide 50, and the air guide 50 can also guide the sliding of the oil droplets.

[0036] Further, at least part of the air guide 50 and the edge of the air collecting opening 211 away from the rack 10 form an oil leakage opening 502. The air guide 50 can guide the oil droplets to the oil leakage opening 502. Since the air guide 50 is arranged close to the inside of the smoke collecting assembly 20, the oil leakage opening 502 formed by the air guide 50 and the edge of the air collecting opening 211 is in communication with the inside of the smoke collecting assembly 20. The oil droplets leaked from the oil leakage opening 502 can drop into the inside of the smoke collecting assembly 20, thereby reducing the technical problem of oil droplets falling outside the hood 1. Alternatively, the air guide 50 can form multiple oil leakage openings 502 with the edge of the air collecting opening 211. Specifically, the air guide 50 can be formed by sheet metal stamping, and then multiple oil leakage openings 502 can be machined at the edge of the air guide 50 connected to the air collecting opening 211. Alternatively, the air guide 50 can also form an oil leakage gap with the edge of the air collecting opening 211.

[0037]

[0038] ​In some embodiments, the maximum distance between the air guide 50 and the edge of the air inlet 211 close to the rack 10 is greater than the distance between the air guide 50 and the edge of the air inlet 211 away from the rack 10. The distance between the air guide 50 and the edge of the air inlet 211 close to the rack 10 can form the air inlet channel 501, and the distance between the air guide 50 and the edge of the air inlet 211 away from the rack 10 can form the oil leakage port 502. The air inlet channel 501 needs to have sufficient air inlet area to ensure the smoke collection performance at the air inlet 211, and the oil leakage port 502 does not need air inlet, only needs to provide oil droplets to fall into the inside of the smoke collection assembly 20. By setting the maximum distance between the air guide 50 and the edge of the air inlet 211 close to the rack 10 to be greater than the distance between the air guide 50 and the edge of the air inlet 211 away from the rack 10, the air inlet channel 501 can have sufficient air inlet area, and the oil droplets passing through the oil leakage port 502 can be considered.

[0039] In combination Figure 6 and Figure 7 In some embodiments, the air inlet 211 includes a first part close to the rack 10 and a second part away from the rack 10, and the air guide 50 covers at least part of the second part in the orthographic projection of the air inlet 211. In other words, the air guide 50 can cover the lower part of the air inlet 211, thereby reducing the visible area of the inside of the smoke collection assembly 20 from the air inlet 211, and improving the appearance of the range hood 1. Optionally, the first part and the second part each account for half of the area of the air inlet 211. In other words, the first part is the upper half of the air inlet 211, and the second part is the lower half of the air inlet 211.

[0040] In some embodiments, the range hood 1 further includes an opening and closing piece 30 movably connected with the smoke collection assembly 20, the opening and closing piece 30 is arranged corresponding to the air inlet 211, and the opening and closing piece 30 is movable relative to the smoke collection assembly 20 to open or close the air inlet 211. In the open state of the opening and closing piece 30, the orthographic projection of the opening and closing piece 30 covers at least the first part. In the open state, the opening and closing piece 30 can not only have the technical effect of gathering smoke, but also increase the amount of oil smoke entering the air inlet 211. On the other hand, the opening and closing piece 30 can also block the upper part of the air inlet 211, thereby further reducing the visible area of the inside of the smoke collection assembly 20 from the air inlet 211, and further improving the appearance of the range hood 1. By setting the opening and closing piece 30 to block the upper half of the air inlet 211 and setting the air guide 50 to block the lower half of the air inlet 211, the possibility of the user directly seeing the inside of the range hood 1 from the air inlet 211 is reduced, thereby improving the appearance of the range hood 1 and improving the user's interactive experience.

[0041] In combination Figures 2 to 5In some embodiments, the air guide 50 comprises an air guide portion 51 and a connecting portion 52, at least two ends of the air guide portion 51 are connected to the edges of the air inlet 211 through the connecting portion 52. The angle between the air guide portion 51 and the plane where the air inlet 211 is located is between 10°-20°. For example, 12°, 15° or 18°. If the angle between the air guide portion 51 and the plane where the air inlet 211 is located is too large, the air guide 50 cannot play a sufficient air guiding effect, and under the same conditions, the area of the air inlet 211 covered by the air guide 50 in the third direction will be reduced, and the technical effect of covering the inside of the smoke exhaust assembly 20 cannot be achieved. If the angle between the air guide portion 51 and the plane where the air inlet 211 is located is too large, the air inlet 211 and the air guide 50 will form a too narrow air inlet channel 501, which will reduce the air inlet amount at the air inlet 211, and may also cause noise.

[0042] In combination Figures 7 to 9 In some embodiments, the range hood 1 further comprises a functional shell 60, which is arranged inside the smoke exhaust main body 21, and the functional shell 60 is provided with an oil guide groove 61 and an oil leakage groove 62 which are in communication with each other, and the oil guide groove 61 is arranged correspondingly to the air inlet 211.

[0043] Further, the range hood 1 further comprises a functional member 70, which is arranged in the lifting main body 22, and the functional member 70 has an inner surface facing the smoke exhaust main body 21 and an outer surface arranged correspondingly to the main air inlet 201, and the oil leakage groove 62 is arranged correspondingly to the inner surface of the functional member 70. The oil guide groove 61 of the functional shell 60 can be arranged correspondingly to the rack 10 to receive oil droplets falling from the rack 10. The oil guide groove 61 can also be arranged correspondingly to the air inlet 211 to receive oil droplets falling from the air guide 50. Further, by arranging the oil leakage groove 62, the oil droplets in the oil guide groove 61 can be directed to flow (for example, fall into an oil cup).

[0044] The functional member 70 can be arranged in the middle of the main air inlet 201, and the outer surface of the functional member 70 can at least prevent the flue gas from entering the smoke exhaust main body 21 from the middle of the main air inlet 201. According to the characteristics of the centrifugal fan of the range hood 1, the negative pressure on both sides of the main air inlet 201 is large, and the negative pressure in the middle is small. In the process of rising, the oil fume on both sides rises faster, and the oil fume in the middle region rises slower. If the middle of the main air inlet 201 is not blocked, the airflow with different rising speeds will collide in the middle region to generate vortex, increasing the noise. By arranging the outer surface of the functional member 70 to prevent and reduce the airflow in the middle from entering the main air inlet 201, the noise generated during the operation of the range hood 1 can be reduced.

[0045] Further, the function shell 60 is arranged between the rack 10 and the function piece 70, and the inner surface of the function piece 70 is arranged corresponding to the oil leakage groove 62, so that the oil droplets can be guided to the back of the function piece 70, and then the back of the function piece 70 can guide the oil droplets to the oil cup. Optionally, the inside of the function shell 60 can be provided with an electric control assembly, which can be arranged corresponding to the front plate of the smoke collection body 21 to accept the touch of the user. Optionally, the lower edge of the function piece 70 is closer to the inside of the smoke collection assembly 20 than the upper edge, or the function piece 70 is arranged downward and inwardly inclined. The above is only an embodiment 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 specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
