[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0032] Combination Figure 1 , Figure 2 and Figure 8 , Figure 1 The arrow in the figure indicates the direction of air inlet to the range hood 1. Figure 2 and Figure 8The arrows in the figure illustrate the direction of the droplets inside the smoke collecting assembly 20. An embodiment of the present application provides a range hood 1. The range hood 1 includes a frame 10, a smoke collecting assembly 20, an oil cup 30 and a liquid guide plate 40. The smoke collecting assembly 20 is connected to the frame 10, and the smoke collecting assembly 20 is installed on the frame 10. The range hood 1 can be installed on a wall through the frame 10 or the smoke collecting assembly 20. The frame 10 is provided with an air outlet (not shown in the figure), and the air outlet can be connected to an external flue through a pipe. The frame 10 includes an outer shell, a volute (not shown in the figure) and a centrifugal impeller (not shown in the figure) arranged in the outer shell, and the centrifugal impeller is arranged in the volute. The volute can be connected to the interior of the smoke collecting assembly 20, and the negative pressure generated by the rotation of the centrifugal impeller can drive the gas in the smoke collecting assembly 20 to the air outlet for discharge. The front side of the smoke collecting assembly 20 is provided with a main air inlet 201, which is provided corresponding to the cooker. The main air inlet 201 can inhale the oil smoke generated during cooking, and then discharge it through the air outlet after passing through the smoke collecting assembly 20 and the rack 10. The oil cup 30 is installed on the smoke collecting assembly 20. The oil cup 30 can collect the droplets dripping from the inside of the smoke collecting assembly 20, thereby reducing the droplets dripping onto the cooker and splashing everywhere.
[0033] In some embodiments, an air collecting port 202 is further formed on the smoke collecting assembly 20, and the air collecting port 202 is located on a side of the main air inlet 201 close to the frame 10. The air collecting port 202 can inhale the gas that is not inhaled by the main air inlet 201, thereby increasing the smoke-inhaling capacity of the range hood 1. The air collecting port 202 can have the same orientation as the main air inlet 201. The air collecting port 202 can also be arranged at an angle to the orientation of the main air inlet 201.
[0034] Specifically, in some embodiments, the smoke collecting assembly 20 includes a side suction part and a top suction part. The side suction part is formed with a main air inlet 201, and the main air inlet 201 can suck the oil smoke from the side of the stove. The top suction part extends from the side suction part toward the front side of the range hood 1, and the top suction part is provided with an air collecting port 202, and the air collecting port 202 is arranged downward, and the top suction part can suck the oil smoke from the top surface of the stove. Optionally, in some embodiments, the air collecting port 202 is correspondingly provided with a guide plate, and the guide plate can improve the negative pressure distribution at the air collecting port 202, thereby improving the smoke collecting capacity of the air collecting port 202. Optionally, the extension direction of the side suction part and the top suction part can be set at a right angle or at an obtuse angle, and the direction of the air collecting port 202 and the direction of the main air inlet 201 can be set at a right angle or at an obtuse angle, which is not specifically limited here.
[0035] Combination Figures 2 to 4 ,as well as Figures 8 to 10In some embodiments, the liquid guide plate 40 is installed inside the smoke collecting assembly 20, and the liquid guide plate 40 includes a main body 41 and a first liquid guide portion 42. The first liquid guide portion 42 is arranged at one end of the main body 41 close to the oil cup 30, and at least part of the first liquid guide portion 42 is inclined in the direction close to the oil cup 30 and close to the inside of the smoke collecting assembly 20, and the first liquid guide portion 42 is arranged corresponding to the oil cup 30. Optionally, in other embodiments, the liquid guide plate 40 may also be at least partially or entirely located outside the smoke collecting assembly 20.
[0036] The liquid guide plate 40 can be installed on the front side of the smoke collecting assembly 20, or on the rear side of the smoke collecting assembly 20, or on both the front side and the rear side of the smoke collecting assembly 20, which is not specifically limited here. The liquid guide plate 40 is arranged on the front side or the rear side of the smoke collecting assembly 20 to reduce the obstruction of the air flow path inside the smoke collecting assembly 20, thereby reducing the influence on the suction of the range hood 1.
[0037] By setting the liquid guide plate 40, the liquid droplets inside the smoke collecting assembly 20 can be guided to the first liquid guide part 42 along the main body 41 under the action of the wall effect. The first liquid guide part 42 is set corresponding to the oil cup 30, and the liquid droplets dripping from the first liquid guide part 42 can fall into the oil cup 30. By setting the first liquid guide part 42 to be inclined, the liquid droplets can be guided to the inside of the smoke collecting assembly 20, so that the oil cup 30 can receive the liquid droplets dripping from the first liquid guide part 42 in the area close to the inside of the smoke collecting assembly 20, thereby reducing the part of the oil cup 30 protruding from the smoke collecting assembly 20, so as to reduce the size of the oil cup 30, and further reduce the occupation of the cooking space. The first liquid guide part 42 is set corresponding to the oil cup 30, which means that the orthographic projection of the first liquid guide part 42 in the arrangement direction of the frame 10 and the smoke collecting assembly 20 falls in the oil cup 30. Optionally, during the use of the range hood 1, the orthographic projection of the first liquid guide part 42 in the gravity direction falls in the oil cup 30. In other embodiments, the main body 41 may also be used only to install the first liquid guiding portion 42 on the smoke collecting assembly 20 .
[0038] In some embodiments, the smoke collecting assembly 20 includes a front plate 21 and a rear plate 22 spaced apart in a first direction, a liquid guide plate 40 is mounted on the front plate 21, and a main air inlet 201 is arranged on one side of the smoke collecting assembly 20 having the front plate 21. The side (i.e., the front side) of the smoke collecting assembly 20 having the front plate 21 has a main air inlet 201. In order to ensure sufficient air intake, the main air inlet 201 will minimize the shielding of components, so that the liquid droplets at the main air inlet 201 mainly fall into the oil cup 30 by dripping, and are less likely to slide into the oil cup 30 by drainage or diversion. By arranging the liquid guide plate 40 on the front plate 21, the liquid droplets can be diverted to the inside of the smoke collecting assembly 20 through the first liquid guide portion 42, thereby reducing the possibility of the liquid droplets dripping from the main air inlet 201 to the outside of the range hood 1.
[0039] Combination Figure 5 , Figure 6 and Fig.11 In some embodiments, the front plate 21 is disposed on a side of the main air inlet 201 close to the frame 10. The first liquid guide portion 42 is located on a side of the lower end surface of the front plate 21 away from the frame 10. In this way, the side of the first liquid guide portion 42 close to the inside of the smoke collecting assembly 20 can guide the liquid droplets inside the smoke collecting assembly 20, and the side of the first liquid guide portion 42 close to the front plate 21 can guide the liquid droplets gathered on the front plate 21 under the effect of the wall attachment effect, thereby achieving the liquid droplet diversion inside and outside the range hood 1 at the same time.
[0040] Combination Figure 5 and Figure 6 , Figure 6 The arrows in the figure show the direction of the liquid droplets inside and outside the smoke collecting assembly 20. In some embodiments, the first liquid guiding portion 42 includes a first bent portion 421 and a first extending portion 422. The first bent portion 421 extends from the main plate 41 toward the front side of the range hood 1, and the first extending portion 422 extends obliquely from the first bent portion 421 in the direction close to the oil cup 30 toward the inside of the smoke collecting assembly 20. The first extending portion 422 may extend obliquely from the end of the first bent portion 421 close to the front side of the range hood 1. Optionally, the first extending portion 422 may also extend from the position between the first bent portion 421 and the main plate 41.
[0041] Specifically, combined Figure 6 , the front plate 21 is located on the first bent portion 421, and the first bent portion 421 can be extended to the front side of the range hood 1 to form a platform for supporting the front plate 21, and the front plate 21 is arranged on the first bent portion 421. In this way, the droplets gathered by the front plate 21 can be guided toward the outer side of the front side by the first bent portion 421 and the first extension portion 422 during the sliding process, so that the droplets formed by the front plate 21 are guided to the oil cup 30 to reduce the situation where the liquid of the front plate 21 drips outside the range hood 1. The droplets formed inside the smoke collecting assembly 20 can be guided toward the inner side of the smoke collecting assembly 20 by the first bent portion 421 and the first extension portion 422, so that the droplets formed inside the smoke collecting assembly 20 are guided to the oil cup 30. In the above manner, the droplet diversion inside and outside the range hood 1 can be achieved simultaneously. Optionally, the extension length of the first bent portion 421 is greater than the thickness of the front plate 21. Optionally, a projection of the front plate 21 in a direction from the frame 10 toward the smoke collecting assembly 20 falls within the first bending portion 421 .
[0042] In some embodiments, the angle between the first extension portion 422 and the first direction (combined with Figure 6∠A) is greater than 10°. For example, 15°, 20° or 30°. In particular, since it is necessary to take into account both the liquid droplet diversion of the front plate 21 and the liquid droplet diversion inside the smoke collecting assembly 20, if the angle between the first extension portion 422 and the first direction is too small, the adsorption force generated by the wall attachment effect between the liquid droplets formed by the front plate 21 and the first extension portion 422 will be insufficient, and the liquid droplets may drip outside the range hood 1 before being diverted to the top of the oil cup 30.
[0043] In some embodiments, in the first direction, the distance between the end of the first extension portion 422 close to the inside of the smoke collecting assembly 20 and the inner edge of the oil cup 30 close to the front side (combined with Figure 5 The distance C) is between 3mm-10mm. For example, 5mm, 7mm or 9mm. If the distance between the end of the first extension portion 422 close to the inside of the smoke collecting assembly 20 and the inner edge of the oil cup 30 close to the front side is too small, the portion of the first extension portion 422 corresponding to the oil cup 30 will be too small, and the liquid droplets cannot be fully guided to the inside of the smoke collecting assembly 20 and fall into the oil cup 30. If the distance between the end of the first extension portion 422 close to the inside of the smoke collecting assembly 20 and the inner edge of the oil cup 30 close to the front side is too large, the first extension portion 422 will be too long. If the first extension portion 422 is too long, it will occupy the air intake area of the main air inlet 201, causing an increase in the air intake resistance, resulting in a decrease in the smoking effect. If the first extension portion 422 is too long, it will also increase the length of the droplet flow path and the flow resistance, resulting in the droplets being unable to drip into the oil cup 30 in time.
[0044] Combination Figures 8 to 11 In some embodiments, a plurality of air inlet holes 4221 may be provided on the first extension portion 422. The first extension portion 422 needs to direct the droplets to the inside of the smoke collecting assembly 20 as much as possible to reduce the possibility of the droplets dripping outside the smoke hood 1. If the length of the first extension portion 422 is too short, the risk of droplets dripping outside will increase. If the length of the first extension portion 422 is too long, the air inlet resistance will increase and the smoking effect will decrease. In order to improve this technical problem, a plurality of air inlet holes 4221 may be provided on the first extension portion 422 (or the first extension portion 422 may be arranged in a grid shape) to reduce the obstruction of the first extension portion 422 to the air intake. The air inlet holes 4221 may be arranged in a circular or polygonal shape, which is not specifically limited here. The air inlet holes 4221 may be arranged in at least one row in the first direction.
[0045] In some embodiments, in the first direction, the distance between the end of the first extension portion 422 close to the interior of the smoke collecting assembly 20 and the inner edge of the front side of the oil cup 30 (combined with Fig.11The distance D in the figure is greater than 10 mm. When the distance is less than 10 mm, the first extension portion 422 has limited obstruction to the air intake when the air inlet hole 4221 is not provided, and not providing the air inlet hole 4221 can also facilitate the concentrated falling of droplets, thereby reducing the situation where droplets drip separately from the air inlet hole 4221. When the distance between the end of the first extension portion 422 close to the interior of the smoke collecting assembly 20 and the inner edge of the front side of the oil cup 30 is greater than 10 mm, the effect of the first extension portion 422 on the air intake is more obvious, and it is necessary to provide the air inlet hole 4221 to reduce the obstruction of the first extension portion 422 to the air intake. The distance greater than 10 mm can also further guide the droplets to the interior of the smoke collecting assembly 20 and then be introduced into the oil cup 30 through other surfaces of the smoke collecting assembly 20, further reducing the possibility of droplets dripping on the outside of the range hood 1.
[0046] Combination Figures 3 to 5 ,as well as Figures 9 to 11 In some embodiments, the liquid guide plate 40 further includes a second liquid guide portion 43, which is disposed on a side of the first liquid guide portion 42 close to the frame 10, and the second liquid guide portion 43 extends obliquely from the main plate body 41 in the direction toward the frame 10, toward the direction closer to the inside of the smoke collecting assembly 20, and the second liquid guide portion 43 is provided with a liquid leakage hole 431, which is arranged corresponding to the first liquid guide portion 42. By arranging the second liquid guide portion 43 to be inclined toward the inside of the smoke collecting assembly 20 and toward the direction close to the frame 10, the second liquid guide portion 43 can effectively collect and guide the droplets dripping from the top thereof, and play the role of a "funnel", so that the droplets inside the smoke collecting assembly 20 are guided to the main plate body 41 through the second liquid guide portion 43, and then enter the oil cup 30 through the main plate body 41 and the aforementioned first liquid guide portion 42, so as to reduce the splashing problem caused by the droplets directly dripping inside the smoke collecting assembly 20. The leakage hole 431 provided in the second liquid guiding part 43 can leak the collected liquid droplets to the first liquid guiding part 42. Optionally, the leakage hole 431 provided in the second liquid guiding part 43 is provided close to the main board body 41, so that the leaked liquid droplets can be drained along the main board body 41. Optionally, a part of the leakage hole 431 can be provided on the second liquid guiding part 43, and another part of the leakage hole 431 can be provided on the main board body 41, so that the leaked liquid can further fall along the main board body 41.
[0047] Combination Figure 2 , Figure 5 as well as Fig.12 and Fig.13In some embodiments, the smoke machine 1 further includes a liquid guide member 50, which is disposed on a side of the liquid guide plate 40 close to the frame 10, and the liquid guide member 50 further includes a liquid guide body and a liquid guide portion 53, and the liquid guide body is mounted on the frame 10 or the smoke collecting assembly 20. The liquid guide portion 53 is disposed corresponding to the liquid guide plate 40, and the liquid droplets guided by the liquid guide portion 53 can fall on the liquid guide plate 40.
[0048] Specifically, the liquid guide member 50 can be installed in the frame 10, and the droplets dripping in the frame 10 can fall on the liquid guide member 50, and then be guided to the liquid guide plate 40 through the liquid guide portion 53. The liquid guide member 50 can also be set in the smoke collecting assembly 20. On the one hand, the liquid guide member 50 can collect the droplets dripping in the frame 10 and guide them to the liquid guide plate 40 through the liquid guide portion 53, and on the other hand, it can collect the droplets gathered in the smoke collecting assembly 20 and guide them to the liquid guide plate 40 through the liquid guide portion 53. Optionally, the liquid guide member 50 can be a part of the aforementioned top suction part, and the liquid guide member 50 can be provided with the aforementioned air collecting port 202. The droplet aggregation caused by the air entering the air collecting port 202 can be guided to the liquid guide plate 40 through the liquid guide member 50, and finally guided to the oil cup 30.
[0049] Combination Figure 7 , wherein the liquid guiding part 53 extends obliquely from the liquid guiding body in a direction away from the frame 10 toward the front side of the smoke collecting assembly 20. The liquid guiding part 53 is arranged on the side of the liquid guiding plate 40 close to the frame 10. The liquid guiding part 53 can guide the droplets gathered by the liquid guiding part 50 to the front side of the smoke collecting assembly 20, so that the droplets can be guided to the liquid guiding plate 40, so that the liquid guiding plate 40 can collect the droplets dripping from the liquid guiding part 53 and further guide them into the oil cup 30. In the above manner, the technical problem of droplets directly dripping inside the smoke collecting assembly 20 and causing splashing can be reduced.
[0050] In some embodiments, the liquid guiding body further includes a first liquid guiding section 51 and a second liquid guiding section 52, the second liquid guiding section 52 connects the first liquid guiding section 51 and the liquid guiding part 53, and the first liquid guiding section 51 is arranged corresponding to the frame 10. The first liquid guiding section 51 can at least receive a portion of the liquid droplets dripping from the frame 10. Optionally, the first liquid guiding section 51 is provided with an air collecting port 202. The liquid droplet aggregation caused by the air entering the air collecting port 202 can also be diverted through the first liquid guiding section 51. Optionally, the first liquid guiding section 51 is arranged corresponding to the top suction part, the second liquid guiding section 52 is arranged corresponding to the connection part between the top suction part and the side suction part (or is arranged in a contour), and the liquid guiding part 53 is arranged corresponding to the side suction part.
[0051] In some embodiments, the angle between the first liquid guiding section 51 and the first direction is smaller than the angle between the second liquid guiding section 52 and the first direction. The smaller angle of the first liquid guiding section 51 can reduce the flow speed of the droplets and play a role in collecting the droplets. The larger angle of the second liquid guiding section 52 can significantly change the flow direction of the droplets, thereby facilitating the flow of the liquid guiding portion 53. Optionally, the extension length of the first liquid guiding section 51 in the first direction is greater than the extension length of the second liquid guiding section 52 in the first direction.
[0052] In some embodiments, the angle between the first liquid-conducting section 51 and the first direction (combined with Figure 7 ∠D) is between 10°-20°, such as 12°, 15° or 18°. If the angle between the first liquid guiding section 51 and the first direction is too small, the flow resistance of the liquid droplets in the first liquid guiding section 51 is too large, which will cause the liquid droplets to be unable to be effectively guided to the second liquid guiding section 52. If the angle between the first liquid guiding section 51 and the first direction is too large, the flow resistance of the liquid droplets in the first liquid guiding section 51 is too small, the flow speed is too large, and the liquid droplets may be thrown out at the end of the second liquid guiding section 52 and cannot be restrained by the suction of the second liquid guiding section 52.
[0053] In some embodiments, the liquid guide plate 40 further includes a second liquid guide portion 43, which is disposed on a side of the first liquid guide portion 42 close to the frame 10. In the first direction, the shortest distance between the liquid guide member 50 and the end of the second liquid guide portion 43 close to the frame 10 (combined with Figure 5 The distance L in the figure is between 3mm-10mm. For example, 5mm, 7mm or 9mm. Among them, if the shortest distance between the liquid guide part 50 and the end of the second liquid guide part 43 close to the frame 10 is too small, the droplets may fly over the second liquid guide part 43 during the dripping process, resulting in the second liquid guide part 43 being unable to effectively receive the droplets dripping from the liquid guide part 50. If the shortest distance between the liquid guide part 50 and the end of the second liquid guide part 43 close to the frame 10 is too large, the second liquid guide part 53 will occupy too much space inside the smoke collecting component 20, causing the smoking resistance of the smoke collecting component 20 to increase, resulting in a decrease in the smoking ability of the range hood 1.
[0054] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents 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.
