[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0056] The bottom of the inner cavity of current range hoods is exposed, and there are generally exposed protrusions at the bottom of the inner cavity, such as sharp screw tails, some metal burrs, etc., which are not beautiful. In addition, when users wipe the inner cavity of the range hood, towels, brushes and other items are easy to fall to the bottom of the inner cavity. When users pick up items that have fallen at the bottom of the inner cavity, they are easily scratched by the protrusions, resulting in a poor user experience.

[0057] The utility model provides a range hood 100, please refer to Figures 1 to 4 In one embodiment of the utility model, the range hood 100 includes a smoke hood 1 and a blocking member 2, the smoke hood 1 has a rear side wall 11 and two side walls 12 arranged opposite to each other in the transverse direction, the blocking member 2 extends in the transverse direction, the blocking member 2 is connected to the smoke hood 1, and the blocking member 2 is located at the lower end of the rear side wall 11.

[0058] The technical solution of the present invention is to set a blocking member 2 in the smoke hood 1, which can, on the one hand, cover the bottom of the inner cavity of the smoke hood 1 and the protrusions at the bottom of the inner cavity, thereby improving the overall aesthetics of the range hood 100; on the other hand, when the user is wiping the smoke hood 1, when towels, brushes and other items fall, they can be supported to prevent them from falling to the bottom of the inner cavity of the smoke hood 1, thereby preventing the user from being scratched by the protrusions when picking up items that have fallen at the bottom of the inner cavity.

[0059] It should be noted that the specific implementation form of the blocking member 2 is not limited, and it can be in the form of a baffle or a blocking net, etc., as long as it can carry the fallen objects and prevent the user from picking up the objects from the bottom of the inner cavity, there is no limitation here.

[0060] The installation method between the blocking member 2 and the smoke collecting hood 1 is not limited, and may be bonding, clamping, welding, etc., which is not limited here.

[0061] In addition, the smoke hood 1 may also have a front side wall 13 arranged opposite to the rear side wall 11 in the front-to-back direction, the front side wall 13, the rear side wall 11 and the two side walls 12 jointly define the inner cavity of the smoke hood 1, and the blocking member 2 is arranged between the front side wall 13 and the rear side wall 11 to separate the inner cavity in the up and down directions.

[0062] Specifically, the middle and upper parts of the rear side wall 11 of the smoke hood 1 are used to pass smoke, and the blocking member 2 should be arranged to avoid these positions to avoid blocking the smoke. Therefore, the blocking member 2 is located at the lower end of the rear side wall 11, which can avoid blocking the smoke and ensure the smoke absorption effect of the range hood 100.

[0063] In order to install other components on the smoke hood 1, a raised component 14 is provided on the smoke hood 1 at the lower side of the blocking member 2. Specifically, the raised component 14 can be a screw head of a screw, and the screw can be used to connect the smoke hood 1 with other components or to assemble the smoke hood 1. The raised component 14 can also be burrs, iron thorns or other objects on the smoke hood 1 that can easily scratch the user, which is not limited here.

[0064] In the solution of this embodiment, by arranging the blocking member 2 on the raised part 14, the raised part 14 can be shielded to prevent the raised part 14 from being exposed and scratching the user.

[0065] Since the smoke hood 1 is provided with electrical equipment, such as the guide member 3, which needs to be powered, the smoke hood 1 is provided with electrical connection lines, and the blocking member 2 is arranged above the electrical connection lines to shield the electrical connection lines to prevent them from being directly exposed and damaged by the outside world.

[0066] The smoke hood 1 is a vital component of the range hood 100, and its main function is to capture and gather the smoke generated during the cooking process so that it can be discharged outdoors through the fan system to keep the kitchen air fresh. Therefore, an air inlet 16 is provided on the smoke hood 1 to allow smoke to enter the smoke hood 1. In one embodiment, the smoke hood 1 has an air inlet 16, and the blocking member 2 is located at the lower side of the air inlet 16. In this embodiment, the blocking member 2 is arranged at the lower side of the air inlet 16 so that it is staggered with the air inlet 16, and will not block the air inlet 16, so that it will not affect the air intake of the air inlet 16.

[0067] In one embodiment, please refer to Figures 7 to 10 In order to improve the flow efficiency of the intake air flow channel, the rear side wall 11 is provided with a guide member 3 extending in the up-down direction. By providing the guide member 3 extending in the up-down direction, a left and right double flow channel is formed at the front end of the intake air, making the oil fume suction and exhaust smoother.

[0068] At the same time, in order to prevent the blocking member 2 from affecting the installation of the guide member 3, the middle portion of the blocking member 2 is arranged opposite to the guide member 3, and an avoidance groove 25 is provided on the side of the blocking member 2 facing the rear side wall 11, and the avoidance groove 25 is adapted to the guide member 3.

[0069] In the solution of this embodiment, by providing an avoidance groove 25 on the side of the blocking member 2 facing the rear side wall 11, the blocking member 2 will not interfere with the guide member 3 during installation, and will not affect the installation of the guide member 3, so that the guide member 3 can be installed on the smoke hood 1. Moreover, when the blocking member 2 is installed within the height range of the guide member 3, the guide member 3 can also support the middle part of the blocking member 2, thereby improving the stability of the installation of the blocking member 2.

[0070] Specifically, the guide member 3 can be completely fixed. Specifically, the guide member 3 includes an upper rectifying portion 31 and a lower rectifying portion 32 which are sequentially arranged along the up-down direction. The upper rectifying portion 31 and the lower rectifying portion 32 are both fixedly mounted on the rear side wall 11 of the smoke hood 1, wherein the upper rectifying portion 31 contacts the cavity wall of the inner cavity on opposite sides in the front-to-back direction of the smoke hood 1, respectively, and the upper rectifying portion 31 is formed with rectifying side surfaces on opposite sides in the left-to-right direction of the smoke hood 1, the rectifying side surfaces extend in the direction from the air inlet 16 to the smoke exhaust port, and are spaced apart from the cavity wall of the inner cavity in the left-to-right direction, and the distance between the two rectifying side surfaces decreases from the rear to the front. After the oil smoke enters the inner cavity through the air inlet 16, it can be rectified by the upper rectifying part 31 of the guide member 3, so that the oil smoke enters the exhaust port in an approximately parallel manner, thereby preventing the oil smoke from colliding at the exhaust port, thereby reducing the probability of generating collision noise, and thus reducing the noise of the range hood 100; and because the upper rectifying part 31 can rectify the oil smoke into an approximately parallel manner to enter the exhaust port, the probability of the oil smoke on both sides generating vortices can be reduced, thereby reducing the probability of generating aerodynamic noise, and thus reducing the noise of the range hood 100. Furthermore, because the flow rate of the oil smoke near the rear position is larger and more concentrated than the flow rate near the front position, the distance between the two rectifying sides is set to decrease from the rear to the front, thereby better rectifying the oil smoke with a larger flow rate near the rear, and improving the rectifying effect, thereby reducing the noise of the range hood 100.

[0071] Of course, the upper rectifying part 31 of the guide member 3 can also be movably arranged. Specifically, the lower rectifying part 32 is fixedly installed on the rear side wall 11 of the smoke hood 1, and the upper rectifying part 31 is arranged to swing laterally, so that under the swing of the upper rectifying part 31, the cross-sectional area size in the left and right air inlet paths of the range hood 100 changes, and the air intake ratio on the left and right sides is changed. Therefore, accurate smoking can be performed for cooking on the left or right side of the stove, and the single-sided smoking effect is improved. It is suitable for the use of a single stove / single-side stove or steaming and stir-frying, so that the smoking effect is optimally matched and the noise is low.

[0072] Correspondingly, the avoidance groove 25 is adapted to the guide member 3 , and may be adapted to the upper rectifying portion 31 of the guide member 3 , or may be adapted to the lower rectifying portion 32 of the guide member 3 , which is not limited here.

[0073] Taking into account that the upper rectifying portion 31 of some guide members 3 may be movably arranged, when adapted with the upper rectifying portion 31, when the upper rectifying portion 31 moves, it is easy for the blocking members 2 to interfere with each other, or, in order to avoid interference, the avoidance groove 25 needs to be set very large, which will leave a large gap, and objects are easy to fall from the gap to the bottom of the inner cavity. In addition, the upper rectifying portion 31 is generally located at a relatively upper position in the inner cavity. When the blocking member 2 is set at the position of the upper rectifying portion 31, the blocking member 2 may have a certain impact on the smoke intake, thereby affecting the smoke intake efficiency.

[0074] Therefore, in a further embodiment, the guide member 3 includes an upper rectifying portion 31 and a lower rectifying portion 32 sequentially arranged in the up-down direction, the lower rectifying portion 32 is fixedly mounted on the rear side wall 11 , and the avoidance groove 25 is adapted to the lower rectifying portion 32 .

[0075] In the solution of this embodiment, by adapting the avoidance groove 25 to the lower rectifying part 32, since the lower rectifying part 32 is fixedly installed, the groove wall of the avoidance groove 25 can fit with the lower rectifying part 32 without leaving a gap, or the gap is small, which can effectively prevent debris from falling from the gap to the bottom of the inner cavity.

[0076] Moreover, the lower rectifying portion 32 is located at a relatively low position in the inner cavity, and the blocking member 2 will not interfere with the air intake, thus ensuring the air intake efficiency.

[0077] Furthermore, the avoidance groove 25 is adapted to the portion of the lower rectifying portion 32 located below the air inlet 16, so that the blocking member 2 can be installed to the portion of the lower rectifying portion 32 located below the air inlet 16, further avoiding interference of the blocking member 2 with smoke intake.

[0078] It should be emphasized that the avoidance groove 25 can be integrated with the lower rectifying portion 32. When the overall fit is achieved, the blocking member 2 is installed on the outside of the lower rectifying portion 32. Of course, it can also be partially integrated with the lower rectifying portion 32, so that the blocking member 2 can be partially installed inside the lower rectifying portion 32, so that the lower rectifying portion 32 can play a certain supporting and limiting effect on the blocking member 2.

[0079] In a further embodiment, the lower rectifying portion 32 includes a fixing seat 33 and a guide portion 34 which are sequentially arranged along the front-to-rear direction, the fixing seat 33 is fixedly installed on the rear side wall 11, and the avoidance groove 25 is adapted to the fixing seat 33; the fixing seat 33 and the guide portion 34 jointly define an installation channel 35 which is arranged to penetrate in the transverse direction, and the blocking member 2 is passed through the installation channel 35.

[0080] In the technical solution of this embodiment, the avoidance groove 25 is adapted to the fixing seat 33, so that the guide member 3 can be installed on the fixing seat 33, and the fixing seat 33 and the guide portion 34 jointly define a mounting channel 35, so that the blocking member 2 can be inserted into the mounting channel 35, and the mounting channel 35 can limit and support the blocking member 2, thereby further improving the stability of the installation of the blocking member 2.

[0081] It is understandable that the shape of the installation channel 35 can be configured to match the shape of the blocking member 2 , thereby enhancing the effect of supporting and limiting the middle portion of the blocking member 2 .

[0082] It should be noted that the specific implementation form of the guide part 34 is not limited, and it can be a guide plate or a guide slope 24, and its specific function is to guide the smoke at the air inlet 16 toward the upper rectifying part 31. The fixing seat 33 is fixedly installed on the rear side wall 11, so as to provide support for other components of the guide member 3, such as the upper rectifying part 31, the guide part 34, etc.

[0083] Also, see Figures 5 to 7 The blocking member 2 includes a main body portion 21 and an extension portion 22, the main body portion 21 extends in the transverse direction, and the main body portion 21 has a first side end portion and a second side end portion, wherein the first side end portion of the main body portion 21 is arranged opposite to the rear side wall 11; the extension portion 22 is connected to the second side end portion of the main body portion 21 and extends downward; the avoidance groove 25 is arranged at the first side end portion of the main body portion 21.

[0084] The main body 21 extends in the transverse direction, and can partition the inner cavity, carry fallen debris, cover the protrusions and wire harnesses at the bottom of the inner cavity, and improve the aesthetics of the range hood 100 and the user experience.

[0085] By providing the extending portion 22 extending downward, on the one hand, the overall strength of the blocking member 2 can be enhanced, and on the other hand, the extending portion 22 extends downward to avoid obstruction to the air intake. In addition, the extending portion 22 and the main body 21 extend in different directions. When installed in the installation channel 35, the installation channel 35 can be configured to include a first transverse section extending transversely and a vertical section extending in the up-down direction. The main body 21 is installed in the first transverse section, and the extending portion 22 is installed in the vertical section, so that the blocking member 2 can be limited. In the process of installing the blocking member 2, when the blocking member 2 is first installed in the installation channel 35, the installation channel 35 can roughly position the blocking member 2, and no human support is required for the blocking member 2, thereby saving manpower.

[0086] The main body 21 has a first side end and a second side end, and the avoidance groove 25 is arranged at the first side end of the main body 21, so that the first side end of the main body 21 avoids the guide member 3 and leaves an installation position for the guide member 3, while the second side end can be supported by the guide member 3. Specifically, a mounting protrusion is provided on the front side of the fixing seat 33, and the second side end is located above the mounting protrusion to be supported by the mounting protrusion. The extension portion 22 is connected to the second side end of the main body 21 and extends downward, so that it is located on the front side of the mounting protrusion and is clamped by the fixing seat 33 and the guide portion 34, thereby improving the strength of the blocking member 2 and the stability of installation.

[0087] Furthermore, the extension portion 22 is away from the second side end portion and is provided with a folded edge. By providing the folded edge, the overall strength of the blocking member 2 can be further enhanced, and the folded edge and the main body portion 21 can jointly clamp the mounting protrusion in the up and down directions to improve the installation stability of the blocking member 2.

[0088] Correspondingly, the installation channel 35 also includes a second transverse section for installing the folded edge.

[0089] At the same time, the blocking member 2 is a plate-like structure. Compared with the structure of the filter, the plate-like structure does not have pores. The plate-like structure of the blocking member 2 can prevent small debris from falling into the bottom of the inner cavity. Correspondingly, the main body 21 and the extension portion 22 can be formed by splicing multiple plates, or can be formed by bending a complete plate, which is not limited here.

[0090] In order to further enhance the installation stability of the blocking member 2 , a mounting portion 23 is provided on the extending portion 22 , and the mounting portion 23 is used to be connected to the guide member 3 .

[0091] In the solution of this embodiment, by providing the mounting portion 23 , the blocking member 2 can be connected to the flow guide member 3 , so that the flow guide member 3 supports the blocking member 2 , thereby improving the stability of the installation of the blocking member 2 .

[0092] It should be noted that the specific implementation form of the mounting portion 23 is not limited, and it may be in the form of a bonding portion to bond the extension portion 22 to the guide member 3, or in the form of a clamping portion 28, a welding portion, etc., which is not limited here.

[0093] In one embodiment, the mounting portion 23 is a mounting hole. Correspondingly, the mounting hole may be a threaded hole, and the extension portion 22 and the guide member 3 are screwed together via a screw connection. Alternatively, the mounting hole may be a through hole, and the extension portion 22 is arranged in the vertical section of the mounting channel 35. The fixing seat 33 and / or the guide portion 34 are provided with a protrusion corresponding to the mounting hole, so that after the installation is completed, the protrusion is located in the mounting hole, completing the connection between the extension portion 22 and the guide member 3.

[0094] Since the blocking member 2 is arranged in the inner cavity, and the inner cavity can pass smoke, after long-term use, oil droplets will accumulate on the blocking member 2 and the guide member 3. In order to control the falling position of these oil droplets, it is convenient to collect them.

[0095] In one embodiment, a guide slope 24 is provided on the lower side of the extension portion 22 at a position corresponding to the avoidance groove 25. The guide slope 24 is provided at one end close to the avoidance groove 25 in the lateral direction and at the other end away from the avoidance groove 25. The guide slope 24 is gradually inclined downward at a position away from the avoidance groove 25.

[0096] In the scheme of this embodiment, by setting the guide slope 24, since the guide slope 24 is set close to the avoidance groove 25 at one end in the lateral direction, the oil droplets flowing down from the guide member 3 can be guided by the guide slope 24 and drip from the other end of the guide slope 24, so that the dripping position of the oil droplets can be controlled, which facilitates the collection of the oil droplets.

[0097] Correspondingly, the range hood 100 further includes an oil droplet collecting device, which is disposed below the other end of the guide slope 24 to collect the oil droplets guided by the guide slope 24 .

[0098] In order to fix the wire harness at the bottom of the inner cavity, the blocking member 2 has a wire-holding portion 29 extending downward, so that the wire harness at the bottom of the inner cavity can be fixed by providing the wire-holding portion 29 .

[0099] Specifically, the specific implementation form of the wire clamping portion 29 is not limited. It can be in the form of a wire clamping ring, allowing the wire harness to pass through the wire clamping ring to achieve its fixation, or it can be in the form of a wire clamping tube. By setting the wire clamping tube, the wire harness can be fixed between the cable tie and the wire clamping tube. Of course, in one embodiment, the wire clamping portion 29 is a clamping block, and the clamping block is spaced apart from the front side wall 13 of the smoke hood 1, and the front side wall 13 jointly defines a limiting space, and the wire harness is passed through the limiting space, so that the clamping block and the front side wall 13 of the smoke hood 1 can limit the wire harness in the front and rear directions.

[0100] Furthermore, the setting of the wire clamping portion 29 is not restricted, and can be directly extended downward from the main body portion 21. In this case, the wire clamping portion 29 is made to be relatively long as a whole, which will weaken its strength. Therefore, in one embodiment, the wire clamping portion 29 is arranged at the lower side end of the extension portion 22, so that the overall length of the wire clamping portion 29 can be reduced, which simplifies the structure and reduces costs on the one hand, and increases strength on the other hand.
