Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology
[0002] Range hoods have become an indispensable kitchen appliance in modern homes. Their main function is to remove cooking fumes, thus maintaining a pleasant kitchen environment.
[0003] Common integrated range hoods have the following main drawbacks: the fan inevitably generates significant noise as it moves the fumes, resulting in a poor user experience while cooking. To overcome these issues, a split-type range hood has been proposed, achieving a certain degree of noise reduction.
[0004] A split-type range hood mainly consists of a lower chamber and a fan box, which are separated by the flue gas duct. When installing this type of range hood, it is usually necessary to make an opening in the ceiling to install the fan box, at least partially, through the opening, and then connect it to the flue gas duct and the lower chamber.
[0005] During the installation process, the installers first make an opening of a predetermined size in the ceiling, then install a bracket for mounting the fan box on the wall above the ceiling, and then install the fan box on the bracket through the opening in the ceiling.
[0006] However, during the installation process, the installation operator may make installation errors when installing the bracket, which may cause the center of the fan box to deviate from the center of the ceiling opening after the fan box is installed on the bracket, and / or the center of the fan box may also deviate from the center of the lower cavity.
[0007] When the center of the fan box deviates from the center of the ceiling opening by a certain distance, in scenarios where the fan box is partially installed above the ceiling, it may cause direct interference between the fan box and the ceiling; in scenarios where the fan box is completely installed above the ceiling, it may cause bending of the flue gas duct above the ceiling. For example... Figure 1 As shown, when the center of the fan box 1 deviates from the center of the lower cavity 5, it will cause the flue gas duct 4 to bend. When the flue gas duct 4 bends, it can easily lead to poor flue gas flow in the duct. In addition, if a decorative cover needs to be installed on the outside of the flue gas duct 4, it will cause problems such as the inability to install a decorative cover of the existing size.
[0008] Overall, there is still room for improvement in the current split-type range hoods. Utility Model Content

[0071] This utility model provides a range hood that allows the fan box installed above the ceiling to be adjusted in the left and right directions. This reduces the installation difficulty of setting the fan box, flue gas pipe, and lower cavity vertically, avoids bending of the flue gas pipe, ensures smooth exhaust of flue gas, and also enhances the installation adaptability of the decorative cover when it is installed outside the flue gas pipe.
[0072] Please refer to the following for comprehensive information. Figures 2 to 11 This application specification provides a range hood, which may include: a fan box 1, a fan box bracket 2, a wall mount 3, a flue duct 4, and a lower cavity 5; the fan box 1 is for installation entirely or partially above a suspended ceiling, the lower cavity 5 is for installation below the suspended ceiling, the suspended ceiling has an opening, and the flue duct 4 connects the lower cavity 5 and the fan box 1; the wall mount 3 is for installation on the wall above the suspended ceiling; the fan box bracket 2 is for connecting the fan box 1 and the wall mount 3; the wall mount 3 has hooks 31, and the fan box bracket 2 has hanging holes 2. 1. The fan box 1 is hung on the hook 31 of the wall bracket 3 through the hanging hole 21 of the fan box bracket 2, or the wall bracket 3 has a hanging hole 21, the fan box bracket 2 has a hook 31, and the fan box 1 is hung on the hanging hole 21 of the wall bracket 3 through the hook 31 of the fan box bracket 2; the ratio of the width of the hanging hole 21 to the width of the hook 31 is greater than 1, and the hanging hole 21 can be used to adjust the position of the fan box 1 in the left-right direction X relative to the opening of the ceiling and / or the lower cavity 5, so that the fan box 1, the flue gas pipe 4, and the lower cavity 5 are arranged sequentially from top to bottom.
[0073] In the embodiments of this application, the range hood mainly includes: a fan box 1, a fan box bracket 2, a wall bracket 3, a flue duct 4, and a lower cavity 5, etc.
[0074] The fan housing 1 is at least partially installed above the ceiling. The fan housing 1 may include a hollow housing structure and a fan at least partially housed within the housing. The ceiling has an opening of a predetermined size, the size of which can be determined based on the required installation dimensions of the fan housing 1, etc. For example, the opening size of the ceiling may be slightly larger than the cross-sectional size of the fan housing 1, ensuring that the fan housing 1 can pass through or be installed within the ceiling. When the fan housing 1 is fully installed above the ceiling, its lowest point can be located on the ceiling; when the fan housing 1 is partially installed above the ceiling, its sidewalls can pass through the opening in the ceiling.
[0075] The lower cavity 5 is installed below the ceiling. Specifically, the lower cavity 5 is set relatively close to the user's cooking area to collect the oil fumes generated during cooking.
[0076] The lower cavity 5 and the fan box 1 are connected by a flue gas duct 4. When the fan is started, the cooking fumes flow upwards sequentially through the lower cavity 5, the flue gas duct 4, and the fan box 1, and are then discharged to a designated location (such as a public flue). The flue gas duct can be either a rigid or flexible duct.
[0077] In this embodiment, the wall mount 3 is installed on the wall above the ceiling and cooperates with the fan box mount 2 to achieve the positioning and installation of the fan box 1. Generally, the wall mount 3 can be fixed to the wall with fasteners. For example, the wall mount 3 can be fixed to the wall with screws. Of course, the wall mount 3 can be fixed to the wall in other ways and is not limited to the above description. Those skilled in the art may make other changes based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the protection scope of this application.
[0078] In this embodiment, the fan box bracket 2 is used in conjunction with the wall mount bracket 3 to achieve the positioning and installation of the fan box 1. The fan box bracket 2 can be integrated into the fan box 1, or installed on the fan box 1 in a detachable or non-detachable manner. For example, when the fan box bracket 2 is integrated into the fan box 1, the fan box bracket 2 and the fan box 1 form a single structure. For example, as... Figure 3 As shown, when the fan box bracket 2 is installed on the fan box 1, the fan box bracket 2 and the fan box 1 can be two independent components.
[0079] During installation, before assembling the fan box bracket 2 and the wall bracket 3, the wall bracket 3 can be fixed to the wall. When the fan box bracket 2 and the wall bracket 3 are assembled, they form an installation mechanism that is fixed in the height direction (Z), fixed or substantially fixed in the front-to-back direction (Y), and can move a predetermined distance in the left-to-right direction (X). If the current installation position of the wall bracket 3 deviates from the predetermined position in the left-to-right direction (X), causing the center of the fan box 1 to deviate from the predetermined position of the ceiling opening, and / or the center of the fan box 1 to deviate from the center of the lower cavity 5, adjusting the position of the fan box bracket 2 relative to the wall bracket 3 in the left-to-right direction (X) can adjust the center of the fan box 1 to the predetermined position required for installation, thus meeting the installation requirements.
[0080] Overall, by setting the fan box bracket 2 and the wall bracket 3 together, the fan box 1 installed above the ceiling can be adjusted in the left and right direction X. This reduces the installation difficulty of setting the fan box 1, flue gas pipe 4, and lower cavity 5 vertically, avoids bending of the flue gas pipe 4, ensures smooth exhaust of flue gas, and enhances the installation adaptability of the decorative cover when installing it outside the flue gas pipe 4.
[0081] In a specific application scenario, when the center of the fan box 1 deviates from the center of the ceiling opening by a certain distance, for scenarios where the fan box 1 is partially installed above the ceiling, adjusting the position of the fan box bracket 2 relative to the wall bracket 3 adjusts the fan box 1's position in the left-right direction (X), thus preventing direct interference between the fan box 1 and the ceiling. For scenarios where the fan box 1 is completely installed above the ceiling, adjusting the position of the fan box bracket 2 relative to the wall bracket 3 adjusts the fan box 1's position in the left-right direction (X), preventing bending of the flue gas duct 4 above the ceiling. Furthermore, when the center of the fan box 1 deviates from the center of the lower cavity 5, adjusting the position of the fan box bracket 2 relative to the wall bracket 3 adjusts the fan box 1's position in the left-right direction (X), aligning the fan box 1 and the lower cavity 5 in the height direction (Z), preventing bending of the flue gas duct 4 connecting the fan box 1 and the lower cavity 5, and ensuring smooth flue gas flow within the duct. In scenarios where a decorative cover needs to be installed on the outside of flue gas duct 4, the problem of the decorative cover being unable to be installed is avoided because flue gas duct 4 does not bend in the height direction Z.
[0082] Please refer to the following: Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9In this embodiment, the wall mount 3 and the fan box mount 2 are able to move relative to each other in the left-right X direction by means of a hook 31 and a hanging hole 21. Furthermore, the wall mount 3 and the fan box mount 2 can also be able to move relative to each other in the left-right X direction by means of other forms, such as forms equivalent to hook 31 and hanging hole 21, etc., and are not limited to the above description. Those skilled in the art may make other modifications based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should be covered within the scope of protection of this application. In the embodiments of this application, the implementation of hook 31 and hanging hole 21 is mainly used as an example for illustration.
[0083] For example, such as Figure 11 As shown, the wall mount 3 has a hook 31. Figure 10 As shown, the fan box bracket 2 has a hanging hole 21. The fan box 1 is hung on the hook 31 of the wall bracket 3 through the hanging hole 21 of the fan box bracket 2. The ratio of the width of the hanging hole 21 to the width of the hook 31 is greater than 1, so that the hanging hole 21 can be used to adjust the position of the fan box 1 in the left-right direction X relative to the opening of the ceiling and / or the lower cavity 5. This allows the fan box 1, the flue gas pipe 4, and the lower cavity 5 to be arranged sequentially from top to bottom, that is, the flue gas pipe 4 can be arranged vertically without bending when connecting the fan box 1 and the lower cavity 5.
[0084] Alternatively, the wall mount 3 has a hanging hole 21, and the fan box mount 2 has a hook 31. The fan box 1 is hung on the hanging hole 21 of the wall mount 3 via the hook 31 of the fan box mount 2. The ratio of the width of the hanging hole 21 to the width of the hook 31 is greater than 1, so that the hanging hole 21 can be used to adjust the position of the fan box 1 in the left-right direction X relative to the opening of the ceiling and / or the lower cavity 5. This allows the fan box 1, the flue gas pipe 4, and the lower cavity 5 to be arranged sequentially from top to bottom, that is, the flue gas pipe 4 can be arranged vertically, and no bending is required when connecting the fan box 1 and the lower cavity 5.
[0085] In this embodiment, to allow the fan housing bracket 2 to move left and right relative to the wall mount 3, the width of the mounting hole 21 (i.e., its dimension in the left-right direction X) is greater than the width of the hook 31, thus enabling the hook 31 to move relative to the mounting hole 21 in the left-right direction X. Specifically, to ensure sufficient relative movement distance between the hook 31 and the mounting hole 21 in the left-right direction X, the ratio of the width of the mounting hole 21 to the width of the hook 31 is not less than 2. When the ratio of the width of the mounting hole 21 to the width of the hook 31 is not less than 2, a larger adjustment space is provided in the left-right direction X, thereby further reducing the accuracy requirements for installation and lowering the installation difficulty.
[0086] Of course, the ratio of the width of the hanging hole 21 to the width of the hook 31 can be larger, for example, not less than 3. As the ratio of the width of the hanging hole 21 to the width of the hook 31 increases, the hook 31 and the hanging hole 21 have a larger moving distance in the left-right direction X, thereby further reducing the installation accuracy requirements of the wall bracket 3.
[0087] When setting the width of the hanging hole 21 and the width of the hook 31, those skilled in the art can take into account the specific width dimensions of the fan box 1, the strength requirements of the hanging hole 21 and the hook 31 themselves.
[0088] In one embodiment, the width of the hanging hole 21 is not less than 60 mm and / or the width of the hook 31 is less than 30 mm.
[0089] In this embodiment, considering the current dimensions of the fan housing 1, the dimensions of the ceiling opening that mates with it, the strength requirements of the hanging hole 21 and the hook 31, when the width of the hanging hole 21 is not less than 60 mm and the width of the hook 31 is less than 30 mm, the hook 31 and the hanging hole 21, when matched, can achieve a distance adjustment space of at least 30 mm in the left-right direction X, provided that the strength requirements of the hook 31 and the hanging hole 21 themselves are guaranteed. This distance adjustment space is sufficient to compensate for the installation error of the wall mount 3 in the left-right direction X. That is, the installation error of the wall mount 3 in the left-right direction X is generally within 30 mm. When the hook 31 and the hanging hole 21 have an adjustment space of more than 30 mm in the left-right direction X, the installation error can be completely compensated, allowing the position of the fan housing 1 to be adjusted to the pre-designed position.
[0090] In this embodiment, such as Figure 11 As shown, the number of hooks 31 can be one or at least two. For example, when there is one hook 31, it can extend longitudinally along the left-right direction (X). Alternatively, when there are two hooks 31, they can be spaced apart along the left-right direction (X) to ensure installation stability. Of course, the number of hooks 31 can also be more, such as three or more, and multiple hooks 31 can be spaced apart along the left-right direction (X).
[0091] like Figure 10As shown, the number of hanging holes 21 can be one or at least two. For example, when there is one hanging hole 21, it can extend longitudinally along the left-right direction (X). Alternatively, when there are two hanging holes 21, they can be spaced apart along the left-right direction (X) to ensure installation stability. Of course, the number of hanging holes 21 can also be more, such as three or more, and multiple hanging holes 21 can be spaced apart along the left-right direction (X).
[0092] Please refer to the following: Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, in one embodiment, the hanging hole 21 is a U-shaped hole. When the fan box bracket 2 has the hanging hole 21, the U-shaped hole faces downward and is located on the lower side of the fan box bracket 2.
[0093] In this embodiment, the hanging hole 21 can be provided on the fan housing bracket 2, and the hook 31 can be provided on the wall bracket 3. The hanging hole 21 can be in the form of a groove extending upwards from the lower edge of the fan housing bracket, thus forming a U-shaped hole structure with the opening facing downwards. When assembling the fan housing bracket 2 with the hook 31 on the wall bracket 3 using the downward-facing U-shaped hole structure, it facilitates the operation of the installation personnel.
[0094] Please refer to the following: Figure 8 , Figure 9 and Figure 11 In this embodiment, the wall mount 3 can be a longitudinally elongated plate structure with a certain thickness. The wall mount 3 has a top and a bottom that are opposite each other along the height direction Z. The wall mount 3 has a first surface facing the fan housing mount 2 and a second surface facing away from the fan housing mount 2. The hook 31 can have an inclined portion 310 that is tilted from the first surface towards the fan housing mount 2. This inclined portion 310 guides the hanging holes 21 of the fan housing mount 2, allowing for convenient and efficient docking between the hanging holes 21 and the hook 31 during assembly.
[0095] In practical operation, the fan box 1 equipped with the fan box bracket 2 only needs to move the height of the hook 31 relative to the wall bracket 3 in the height direction Z. There is no need to lift the fan box 1 equipped with the fan box bracket 2 too high. The hanging hole 21 on the fan box bracket 2 can then engage with the hook 31 of the wall bracket 3. In addition, since the fan box bracket 2 and the wall bracket 3 are located at the upper part of the ceiling, and the height distance from the ceiling to the top wall is limited, when the fan box 1 equipped with the fan box bracket 2 can be adjusted slightly within the height range to achieve the engagement of the hanging hole 21 and the hook 31, interference between the fan box 1 equipped with the fan box bracket 2 and the top wall can also be avoided.
[0096] Alternatively, in another embodiment, the hanging hole 21 is a U-shaped hole. When the wall bracket 3 has the hanging hole 21, the U-shaped hole faces upward and is located on the upper side of the wall bracket 3.
[0097] In this embodiment, the main difference from the above embodiment is that the positions of the hanging hole 21 and the hook 31 are interchanged. Specifically, the hanging hole 21 can be set on the wall bracket 3, and the hook 31 can be set on the fan box bracket 2.
[0098] The hanging hole 21 can be in the form of a downward-facing groove on the upper side of the wall mount 3, thus forming an upward-facing U-shaped hole structure. When the upward-facing U-shaped hole on the upper side of the wall mount 3 is used to assemble with the upper hook 31 of the fan box mount 2, it also facilitates the operation of the installation personnel.
[0099] In specific operation, the fan box 1 equipped with the fan box bracket 2 only needs to move the height of the hook 31 relative to the wall bracket 3 in the height direction Z. There is no need to lift the fan box 1 equipped with the fan box bracket 2 too high. The hook 31 on the fan box bracket 2 can then engage with the hanging hole 21 of the wall bracket 3. In addition, since the fan box bracket 2 and the wall bracket 3 are located at the upper part of the ceiling, and the height distance from the ceiling to the top wall is limited, when the fan box 1 equipped with the fan box bracket 2 can be adjusted slightly within the height range to achieve the engagement of the hanging hole 21 and the hook 31, interference between the fan box 1 equipped with the fan box bracket 2 and the top wall can also be avoided.
[0100] In one embodiment, the fan box bracket 2 includes a plate-shaped body 201 and folding portions 202 located on both sides of the plate-shaped body 201. The plate-shaped body 201 is provided with the hanging hole 21 or the hook 31. The plate-shaped body 201 is close to the rear side of the fan box 1, and the folding portions 202 are used to connect with the left and right sides of the fan box 1.
[0101] In this embodiment, the fan housing 1 can be a plate-like structure with a certain thickness, which may include a plate-like main body 201 and folding portions 202 located on both sides of the plate-like main body 201. The plate-like main body 201 is located near the rear side of the fan housing 1, and has hanging holes 21 or hooks 31 for cooperating with the wall mount 3. The folding portions 202 can be folding plate structures formed at both ends of the plate-like main body 201, and can be used to connect with the left and right sides of the fan housing 1, thereby fixing the fan housing mount 2 relative to the fan housing 1.
[0102] Taking the fan box bracket 2 fixed to the fan box 1 at the folding part 202 via a connector as an example, the fan box bracket 2 has a certain amount of movement in the front-rear direction Y due to the matching structure of the hook 31 and the hanging hole 21 in the direction perpendicular to the rear side of the fan box 1. If the connector is directly set between the rear side of the fan box 1 and the fan box bracket 2, the connector will be subjected to axial force during use and is prone to loosening. When the connector is set at the folding part 202 and connected to the left and right sides of the fan box 1 respectively, the connector is subjected to radial force and is not prone to loosening, resulting in high connection reliability and stability.
[0103] Please refer to the following: Figure 2 and Figure 3 In one embodiment, the fan box 1 includes a left side plate 11, a right side plate 12, a front side plate 13 and a rear side plate 14. The smoke outlet of the fan box 1 is located on the left side plate 11 or the right side plate 12. The front side plate 13 and the rear side plate 14 are both provided with mounting parts for connecting the fan box bracket 2.
[0104] In this embodiment, the cross-section of the fan box 1 can be rectangular or rectangular in shape. The fan box 1 can include opposing left side plate 11 and right side plate 12, as well as opposing front side plate 13 and rear side plate 14.
[0105] For the fan box 1, there are two possible installation environments: one where the common exhaust duct is located on the left side of the range hood, and the other where the common exhaust duct is located on the right side of the range hood. To enable the range hood to be installed in both situations, allowing it to be mounted on either side, the front panel 13 and rear panel 14 of the fan box 1 are each provided with mounting portions for connecting the fan box bracket 2.
[0106] For example, please combine Figure 2 and Figure 14As shown, when the common flue is located on the left side of the range hood, the exhaust port of the fan box 1 can be set to face left. In this case, the fan box bracket 2 can be set as a whole on the rear side of the fan box 1 and connected to the fan box 1 through the mounting part of the rear side plate 14. Alternatively, when the common flue is located on the right side of the range hood, the fan box 1 can be rotated 180° (equivalent to swapping the front and rear sides, and the left and right sides of the fan box 1), so that the exhaust port faces right. In this case, the fan box bracket 2 can still be set as a whole on the rear side of the fan box 1 and connected to the fan box 1 through the mounting part of the rear side plate 14. Figure 2 The mounting portion of the front side panel 13 shown is connected to the fan box 1.
[0107] The mounting part can be in the form of openings on the front side plate 13 and the rear side plate 14. Of course, the mounting part can also take other forms. In this embodiment, the mounting part is illustrated by an opening. The fan box bracket 2 can be fixedly installed by engaging the openings on the front side plate 13 or the rear side plate 14 of the fan box 1 with a connector.
[0108] Please refer to the following: Figure 10 and Figure 14 In one embodiment, the fan housing 1 may include a left side plate 11, a right side plate 12, a front side plate 13, and a rear side plate 14. The front side plate 13 and / or the rear side plate 14 are provided with a first opening 101. The left side plate 11 and the right side plate 12 are both provided with a second opening 102. The fan housing 1 also includes a connector for passing through the first opening 101 and the second opening 102 to connect the front side plate 13, the left side plate 11, and the right side plate 12 and / or to connect the rear side plate 14, the left side plate 11, and the right side plate 12. The fan housing bracket 2 is provided with a third opening 203. The connector is used to pass through the third opening 203, the first opening 101, and the second opening 102 to connect the fan housing bracket 2 to the fan housing 1.
[0109] In this embodiment, the cross-section of the fan housing 1 can be rectangular or rectangular in shape. The fan housing 1 may include a left side plate 11, a right side plate 12, a front side plate 13, and a rear side plate 14. Adjacent side plates of the fan housing 1 can be connected by connectors.
[0110] Specifically, at least one of the front side panel 13 and the rear side panel 14 is provided with a first opening 101 for engaging with a connector. Both the left side panel 11 and the right side panel 12 are provided with a second opening 102 for engaging with a connector. In specific connection, when the front side panel 13 has a first opening 101, the connector can pass through both the first opening 101 and the second opening 102 to connect the front side panel 13 to the left side panel 11 and the right side panel 12. Similarly, when the rear side panel 14 has a first opening 101, the connector can pass through both the first opening 101 and the second opening 102 to connect the rear side panel 14 to the left side panel 11 and the right side panel 12.
[0111] Furthermore, the fan box bracket 2 is provided with a third opening 203, and the connector is used to pass through the third opening 203, the first opening 101, and the second opening 102 to connect the fan box bracket 2 to the fan box 1. With this configuration, when the fan box bracket 2 is connected to the fan box 1 via the connector, structurally, by sharing the first opening 101 and the second opening 102 on the fan box 1, the number of openings in the fan box 1 can be reduced, thereby reducing oil leakage locations, and also saving on the number of connectors. In addition, in terms of process, the step of separately creating the connecting hole can be eliminated, and the step of connecting the fan box bracket 2 to the fan box 1 can be combined with the connection between the side plates of the fan box 1, thereby simplifying the process and reducing operation steps.
[0112] Please refer to the following: Figure 2 , Figure 10 , Figure 12 and Figure 14 In one specific embodiment, the fan box 1 includes a left side plate 11, a right side plate 12, a front side plate 13, and a rear side plate 14. Both sides of the front side plate 13 and / or the rear side plate 14 are provided with flanges 18, each flange 18 having a first opening 101. Both the left side plate 11 and the right side plate 12 have second openings 102. The fan box 1 also includes a connector, which passes through the first openings 101 and the second openings 102 to connect the front side plate 13, the left side plate 11, and the right side plate 12, and / or to connect the rear side plate 14, the left side plate 11, and the right side plate 12. Both sides of the fan box bracket 2 are provided with third openings 203, and the connector passes through the third openings 203, the first openings 101, and the second openings 102 to connect the fan box bracket 2 to the fan box 1.
[0113] In this embodiment, both sides of the front side panel 13 of the fan box 1 can be provided with flanges 18, and both sides of the flanges 18 can be provided with first openings 101. Both sides of the rear side panel 14 of the fan box 1 can be provided with flanges 18, and both sides of the flanges 18 can be provided with first openings 101.
[0114] Taking the rear side panel 14 with a first opening 101 as an example, the flanges 18 on both sides of the rear side panel 14 can be set towards the left side panel 11 and the right side panel 12. The flanges 18 of the rear side panel 14 can cover the outside of the left side panel 11 and the right side panel 12, and the first opening 101 on the flange 18 can at least partially overlap with the second opening 102 on the left side panel 11 and the right side panel 12, so that the connector can pass through the first opening 101 and the second opening 102 at the same time, realizing the connection between the rear side panel 14 and the left side panel 11 and the right side panel 12.
[0115] The number and corresponding distribution positions of the first opening 101, the second opening 102, and the third opening 203 can be the same. Taking the third opening 203 as an example, there can be three third openings 203. The lines connecting the three third openings 203 can form a non-collinear triangular structure along the plane where the flange 18 is located, thereby further ensuring the reliability and stability of the connection. In addition, the first opening 101 can be a through hole for inserting the connector, and the second opening 102 can be a threaded hole that can cooperate with the connector to form a fastening structure. For the third opening 203, its specific form can be an oblong hole, thereby reducing the installation accuracy requirements when the third opening 203 is installed with the first opening 101 and the second opening 102 through the connector. Of course, the above description of the number, position, and shape of the openings is only an example of a typical embodiment. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the scope of protection of this application.
[0116] In addition to the technical effects of the shared openings, the above-mentioned connector and the mating structure of the first opening 101, the second opening 102 and the third opening 203 have the advantage of being located on the flange 18 of the rear side plate 14. In use, the connector is subjected to radial force and is not easy to loosen, thus ensuring better connection reliability and stability.
[0117] Furthermore, the fitting relationship of the first opening 101 on the front side plate 13 and the technical effects it produces can be referred to the specific description of the rear side plate 14 above, and will not be described in detail here.
[0118] In one embodiment, the fan box bracket 2 is located on the upper part of the fan box 1; the range hood also includes a hanging ear, which is used to install on the fan box 1 to connect the fan box 1 and the wall.
[0119] In this embodiment, the fan box bracket 2 can be located on the upper part of the fan box 1, and the fan box 1 forms a positioning and installation mechanism through the cooperation between the fan box bracket 2 and the wall bracket 3. In order to ensure the stability and reliability of the installation of the fan box 1, for the case where the fan box bracket 2 is located on the upper part of the fan box 1, an installation cooperation mechanism is also added in this embodiment.
[0120] Specifically, to ensure the stability of the connection between the fan housing 1 and the wall, the range hood can also be equipped with mounting ears. These mounting ears are installed on the fan housing 1 and used to connect the fan housing 1 to the wall. Specifically, the mounting ears can be located below the fan housing bracket 2, for example, at the lower part of the fan housing 1. The mounting ears can be integrally constructed with the fan housing 1, or they can be installed on the fan housing 1 in a detachable or non-detachable manner.
[0121] The mounting lug can be a plate-like structure with an approximate L-shaped cross-section. It has a mounting surface facing the side wall of the fan housing 1, and a second mounting surface for mating with a fastener on the wall. The second mounting surface may have an opening for mating with the fastener on the wall.
[0122] Of course, the connection between the fan box bracket 2 and the wall bracket 3 is not limited to the examples above. The specific setting of the hanging ears can also be in other ways, and is not limited to the above description. Those skilled in the art may make other changes under the inspiration of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the protection scope of this application.
[0123] Please refer to the following: Figures 12 to 13 In one embodiment, the inner side of the fan box 1 is connected to a bracket 17 without holes. The bracket 17 is used to connect a hollow limiting plate 15. Sound-absorbing cotton 16 is provided between the limiting plate 15 and the inner side.
[0124] In this embodiment, the fan housing 1 contains a fan, which is the source of noise. To reduce the noise transmitted to the outside when the fan is working, a noise reduction structure can be provided on the inner side of the fan housing 1.
[0125] Specifically, the noise reduction structure can take the form of sound-absorbing cotton 16. To fix the sound-absorbing cotton 16 to the inner side of the fan housing 1, a limiting plate 15 can be provided. This limiting plate 15 can be fixed to the fan housing 1 via a connecting mechanism, thereby positioning the sound-absorbing cotton 16.
[0126] Specifically, the connecting mechanism can be a bracket 17 installed on the inner side of the fan housing 1 through a holeless connection. When the bracket 17 is installed on the inner side of the fan housing 1 through a holeless connection, there is no need to make holes on the inner side of the fan housing 1, thus preventing oil from seeping out through the opening.
[0127] Specifically, the bracket 17 can be roughly in the shape of a "Z" and has a first fixing part 171 and a second fixing part 172 for fixing to the inner side of the fan box 1 and a support part 173 located between the first fixing part 171 and the second fixing part 172. The support part 173 protrudes from the inner side of the fan box 1 at a predetermined height, which is used to ensure that a sound-absorbing cotton 16 with a sufficiently high thickness can be installed.
[0128] The limiting plate 15 can be connected to the bracket 17 via a connector. Multiple brackets 17 can be used, and when these brackets 17 engage with the limiting plate 15 via the connector, they reliably confine the sound-absorbing cotton 16 within the limiting plate 15 and the fan housing 1. Specifically, for example, the limiting plate 15 can have the aforementioned hollow structure with an internal cross-shaped frame, and there can be five brackets 17. Four brackets 17 are distributed at the four apex corners of the limiting plate 15, and one bracket 17 is located in the center of the limiting plate 15, at the center of the cross-shaped frame.
[0129] When the sound-absorbing cotton 16 is located between the limiting plate 15 of the hollow structure and the inner side of the fan box 1, it can ensure that the sound-absorbing cotton 16 has better fluffiness, thereby achieving an ideal noise reduction effect.
