Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a smoke collection component and a range hood. Background Technology

[0002] As people's living standards improve, their demands for the kitchen cooking environment are also increasing. Range hoods have become an indispensable kitchen appliance in modern homes. A range hood works by using a motor to drive an impeller at high speed, creating a negative pressure zone near the smoke collection chamber. This pressure draws cooking fumes into the machine through the air inlet and exhausts them outdoors.

[0003] Existing range hoods often include an upper smoke collection chamber and a lower smoke collection chamber, which are connected in a figure-7 shape. The upper and lower smoke collection chambers are usually equipped with upper and lower air inlets, respectively. In order to ensure air intake efficiency and smoke extraction effect, the upper and lower air inlets are usually equipped with upper and lower air intake chambers and upper and lower guide plates, which results in a large thickness of the upper and lower smoke collection chambers, occupying too much space. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a smoke collection assembly is provided, the technical solution of which is as follows.

[0005] The smoke collection assembly includes a mounting plate, a front plate, a side plate, and a guide plate. The mounting plate, side plate, and front plate enclose a first smoke collection chamber and a second smoke collection chamber. The first smoke collection chamber is connected to the second smoke collection chamber. The second smoke collection chamber is located above the first smoke collection chamber and protrudes from the first smoke collection chamber. The front plate is connected to an air inlet. An annular air inlet is formed between the air inlet and the guide plate. The air inlet has a first air inlet portion and a second air inlet portion. The first air inlet portion connects the first smoke collection chamber and the annular air inlet, and the second air inlet portion connects the second smoke collection chamber and the annular air inlet. The guide plate blocks at least a portion of the first air inlet portion and at least a portion of the second air inlet portion.

[0006] The smoke collection assembly of this utility model forms an integral air inlet that connects the first smoke collection chamber and the second smoke collection chamber through the air inlet component and the guide plate. The guide plate not only blocks the first air inlet but also blocks the second air inlet. This not only makes the structure simple but also ensures the thinness of the smoke collection assembly, while ensuring air intake efficiency and smoke extraction effect.

[0007] For example, a first air inlet extends into a first smoke collection chamber, and a second air inlet extends into a second smoke collection chamber. The first and second air inlets together form an air inlet chamber with one end open. A guide plate is disposed at the opening, and an annular air inlet is formed between the outer edge of the guide plate and the wall of the air inlet chamber. Thus, by forming an air inlet chamber with one end open through the enclosing of the first and second air inlets, the air inlet area is increased based on the integral air inlet chamber design, further ensuring air intake efficiency and smoke extraction effect. Simultaneously, the thickness of the first and second smoke collection chambers is more effectively controlled, making the overall smoke collection assembly thinner.

[0008] For example, the first air inlet is provided with a first air inlet hole, and the first smoke collection chamber is connected to the air inlet cavity through the first air inlet hole. The second air inlet is provided with a second air inlet hole, and the second smoke collection chamber is connected to the air inlet cavity through the second air inlet hole. In this way, the oil fumes can enter the first and second smoke collection chambers more smoothly, and the first and second air inlets can perform preliminary filtration of the oil fumes, intercepting larger oil fume particles and other foreign objects, thus extending the service life of the smoke collection assembly.

[0009] For example, the first air inlet extends from the front panel toward the mounting plate, and the second air inlet extends upward from the front panel; or, the air inlet has a mounting portion fixedly connected to the front panel, the first air inlet extends from the mounting portion toward the mounting plate, and the second air inlet extends upward from the mounting portion. When the first air inlet extends from the front panel toward the mounting plate and the second air inlet extends upward from the front panel, the air inlet can be formed by stretching the front panel, thus the air inlet and the front panel are an integral structure, facilitating processing and molding; when the air inlet has a mounting portion, the air inlet and the front panel are separate structures.

[0010] For example, the annular air inlet has an annular width D, which is 30mm ≤ D ≤ 40mm. Setting the annular width D within this range ensures the efficiency of air intake and smoke extraction when oil fumes enter the air intake cavity through the annular air inlet, and avoids the problem of an excessively large annular air inlet causing unsightly appearance.

[0011] For example, the guide plate is provided with a connecting part, and the cavity wall of the air inlet is provided with a connecting mating part. The guide plate is detachably connected to the cavity wall of the air inlet through the connecting part and the connecting mating part. In this way, it is convenient to install the guide plate, and the guide plate is detachably connected to the cavity wall of the air inlet, which makes it convenient for the user to clean and replace the guide plate.

[0012] For example, the front panel has a first plate and a second plate, the first plate being opposite to the mounting plate, the second plate being connected to the upper end of the first plate, a first air inlet being connected to the first plate, and a second air inlet being connected to the second plate. This allows for full utilization of space, maximizing the size of the air inlet cavity, thereby ensuring air intake efficiency and smoke extraction effectiveness.

[0013] For example, the guide plate has a first guide portion and a second guide portion, with the second guide portion connected to the upper end of the first guide portion. When the guide plate is connected to the cavity wall of the air inlet chamber, the first guide portion is flush with the first plate body, and the second guide portion is flush with the second plate body. In this way, the overall aesthetics of the machine are effectively guaranteed, and the problem of increased thickness caused by the guide plate protruding from the front plate is avoided.

[0014] For example, the first air inlet has a first top wall, a first air inlet hole is disposed on the first top wall, and the projection of the first guide portion toward the first top wall covers at least part of the first air inlet hole. In this way, the first guide portion can shield the first air inlet hole, ensuring the aesthetics of the whole machine.

[0015] For example, the second air inlet has a second top wall, a second air inlet hole is disposed on the second top wall, and the projection of the second guide portion toward the second top wall covers at least part of the second air inlet hole. In this way, the second guide portion can shield the second air inlet hole, ensuring the aesthetics of the entire machine.

[0016] For example, the first guide section and the second guide section have an included angle α, where α > 90°. Setting the included angle α within this range effectively avoids the problem of oil accumulation on the guide plate.

[0017] For example, in the width direction of the first plate, the first air inlet has a first maximum width M1, where 60mm ≤ M1 ≤ 280mm. The first maximum width M1 is set within this range, which effectively ensures the basic air inlet area, thereby ensuring air inlet efficiency and avoiding the problem of an excessively large air inlet cavity causing unsightly appearance.

[0018] For example, the first air inlet has a first top wall, and a first air inlet hole is disposed on the first top wall. In the width direction of the first plate, the first top wall has a first width W1, where W1 = 0.6M1. When the first maximum width M1 and the first width W1 have this relationship, the air inlet area is effectively guaranteed, thereby ensuring the air inlet efficiency.

[0019] For example, in the width direction of the second plate, the second air inlet has a second maximum width M2, where 60mm ≤ M2 ≤ 280mm. The second maximum width M2 is set within this range, which effectively ensures the basic air inlet area, thereby ensuring air inlet efficiency and avoiding the problem of an excessively large air inlet cavity causing an unsightly appearance.

[0020] For example, the second air inlet has a second top wall, and a second air inlet hole is disposed on the second top wall. In the width direction of the second plate, the second top wall has a second width W2, where W2 = 0.6M2. When the second maximum width M2 and the second width W2 have this relationship, the air inlet area is effectively guaranteed, thereby ensuring the air inlet efficiency.

[0021] For example, the air inlet cavity has a length L in the longitudinal direction of the front panel, where L ≤ 460 mm. Setting the length L within this range effectively ensures the basic air inlet area, thereby guaranteeing air inlet efficiency and avoiding the problem of an excessively large air inlet cavity affecting the overall appearance of the machine.

[0022] For example, the first air inlet has a first top wall, and a first air inlet hole is disposed on the first top wall. In the length direction of the front panel, the first top wall has a first length L1, where L1 = 0.75L. When the length L and the first length L1 have this relationship, the air inlet area is effectively guaranteed, thereby ensuring air inlet efficiency and avoiding the problem of an excessively large annular air inlet causing unsightly appearance.

[0023] For example, the second air inlet has a second top wall, and a second air inlet hole is disposed on the second top wall. In the length direction of the front panel, the second top wall has a second length L2, where L2 = 0.75L. When the length L and the second length L2 have this relationship, the air inlet area is effectively guaranteed, thereby ensuring air inlet efficiency, and avoiding the problem of an excessively large annular air inlet causing unsightly appearance.

[0024] For example, the second plate has an upper extension extending upward from the end away from the first plate, and the upper extension has a height H, where H ≤ 35 mm. Setting the height H within this range effectively reduces the thickness of the second smoke collection chamber, reduces the space occupied by the second smoke collection chamber, and makes the whole machine thinner.

[0025] For example, the end of the first plate away from the second plate has a distance S between it and the mounting plate, where S ≤ 35 mm. Setting the distance S within this range effectively reduces the thickness of the first smoke collection chamber, reduces the space occupied by the first smoke collection chamber, and makes the whole machine thinner.

[0026] According to another aspect of this utility model, a range hood is provided, including a fan assembly and a smoke collection assembly as described above, wherein the smoke collection assembly is disposed below the fan assembly. The air inlet cavity is directly located below the fan assembly, resulting in smoother airflow, which not only improves airflow efficiency but also reduces the load. Furthermore, since the smoke collection assembly described above has the aforementioned beneficial effects, the range hood including the smoke collection assembly also has the aforementioned beneficial effects, which will not be elaborated further here.

[0027] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0039] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0040] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0041] This utility model provides a smoke collection assembly. The smoke collection assembly provided by this utility model can be applied to range hoods. The following will describe in detail one embodiment of the smoke collection assembly according to the accompanying drawings.

[0042] See also Figures 1 to 7 The smoke collection assembly 10 may include a mounting plate 110, a front plate 120, a side plate 130, and a guide plate 160. The mounting plate 110, side plate 130, and front plate 120 may enclose a first smoke collection chamber 140 and a second smoke collection chamber 150. The first smoke collection chamber 140 may communicate with the second smoke collection chamber 150. The second smoke collection chamber 150 may be located above the first smoke collection chamber 140 and protrude from the first smoke collection chamber 140. The front plate 120 may be connected to an air inlet 170. An annular air inlet 180 may be formed between the air inlet 170 and the guide plate 160. The air inlet 170 may have a first air inlet portion 171 and a second air inlet portion 172. The first air inlet portion 171 may connect the first smoke collection chamber 140 and the annular air inlet 180. The second air inlet portion 172 may connect the second smoke collection chamber 150 and the annular air inlet 180. The deflector 160 can block at least part of the first air inlet 171 and at least part of the second air inlet 172, such that a portion of the deflector 160 forms a partial annular air inlet 180 between the first air inlet 171 and another portion of the deflector 160 forms a partial annular air inlet 180 between the second air inlet 172 and the first air inlet 171.

[0043] The smoke collection assembly 10 of this utility model forms an integral air inlet that connects the first smoke collection chamber 140 and the second smoke collection chamber 150 through the air inlet 170 and the guide plate 160. The guide plate 160 not only blocks the first air inlet 171 but also blocks the second air inlet 172. Compared with the structure where the upper and lower air inlets correspond to the upper and lower air inlets and the upper and lower guide plates respectively, the structure is not only simple but also ensures the thinness of the smoke collection assembly 10, while ensuring air intake efficiency and smoke extraction effect.

[0044] Specifically, the mounting plate 110 can be installed on a mounting surface. The mounting surface can be a wall, cabinet wall, etc. When the smoke collection assembly 10 is installed, the front panel 120 can be located on the side of the smoke collection assembly 10 closer to the operator.

[0045] It should be noted that the air intake area refers to the total area of ​​the fumes entering the first smoke collection chamber 140 and the second smoke collection chamber 150 through the air intake component 170. Understandably, a larger air intake area results in smoother airflow and higher air intake efficiency.

[0046] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first air inlet 171 can extend into the first smoke collection chamber 140. The second air inlet 172 can extend into the second smoke collection chamber 150, and the first air inlet 171 and the second air inlet 172 can enclose to form an air inlet chamber 173 with an opening 1731 at one end. A guide plate 160 can be disposed at the opening 1731. An annular air inlet 180 can be formed between the outer edge of the guide plate 160 and the cavity wall of the air inlet chamber 173. Thus, the first air inlet 171 and the second air inlet 172 enclose to form an air inlet chamber 173 with an opening 1731 at one end.

[0047] Based on the integrated air inlet cavity design, the air inlet area is increased, further ensuring air inlet efficiency and smoke extraction effect. At the same time, the thickness of the first smoke collection cavity 140 and the second smoke collection cavity 150 is controlled more effectively, making the smoke collection assembly 10 thinner overall.

[0048] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The first air inlet 171 can extend from the front panel 120 toward the mounting plate 110. The second air inlet 172 can extend upward from the front panel 120. The air inlet 170 can be formed by stretching the front panel 120, so that the air inlet 170 and the front panel 120 are an integral structure, which is convenient for processing and molding.

[0049] In an embodiment not shown, the air inlet 170 may have a mounting portion. The mounting portion may be fixedly connected to the front panel 120. A first air inlet 171 may extend from the mounting portion toward the mounting plate 110. A second air inlet 172 may extend upward from the mounting portion. The mounting portion, the first air inlet 171, and the second air inlet 172 may be an integral structure, thus allowing simultaneous assembly and disassembly of the first air inlet 171 and the second air inlet 172 for easy installation. Alternatively, the assembly consisting of the mounting portion and the first air inlet 171 and the second air inlet 172 may be inserted into the first smoke collection chamber 140 and the second smoke collection chamber 150, respectively, and the front panel 120 may be connected to the mounting portion by adhesive bonding, snap-fitting, threaded connection, or other suitable methods. During installation, the entire air inlet 170 forms an assembly. When the air inlet 170 has a mounting portion, the air inlet 170 may be detachable from the front panel 120.

[0050] In an embodiment not shown, the first air inlet 171 and the second air inlet 172 may be flush with the front panel 120, or they may protrude from the front panel 120.

[0051] To connect the first smoke collection chamber 140 and the annular air inlet 180, the first air inlet 171 can adopt a structure with openings in the plate. Similarly, to connect the second smoke collection chamber 150 and the annular air inlet 180, the second air inlet 172 can also adopt a structure with openings in the plate. (See also...) Figure 1 , Figure 2 and Figure 5 A first air inlet 1701 can be provided on the first air inlet 171. The first smoke collection chamber 140 can be connected to the air inlet chamber 173 through the first air inlet 1701. A second air inlet 172 can be provided on the second air inlet 172. The second smoke collection chamber 150 can be connected to the air inlet chamber 173 through the second air inlet 1702. In this way, the oil fumes can enter the first smoke collection chamber 140 and the second smoke collection chamber 150 more smoothly, and the first air inlet 1701 and the second air inlet 1702 can perform preliminary filtration of the oil fumes, intercepting larger oil fume particles and other foreign objects, thus extending the service life of the smoke collection assembly 10.

[0052] Understandably, the air intake area at this time is the total area of ​​the first air intake 1701 and the second air intake 1702.

[0053] It should be noted that the basic air intake area refers to the total area through which cooking fumes can pass when entering the air intake cavity 173 from the outside, i.e., the area of ​​the opening 1731. When a baffle 160 is installed at the opening 1731, the basic air intake area is the area of ​​the integral air intake, i.e., the area of ​​the annular air intake 180. Understandably, the larger the basic air intake area, the smoother the air intake and the higher the air intake efficiency.

[0054] See again Figure 2 , Figure 4 , Figure 6 and Figure 7 The annular air inlet 180 can have a ring width D, where 30mm ≤ D ≤ 40mm. For example, the ring width D can be 30mm, 37mm, 40mm, etc. Setting the ring width D within this range ensures the efficiency of air intake and smoke extraction when oil fumes enter the air intake cavity 173 through the annular air inlet 180, and avoids the problem of the annular air inlet 180 being too large and unsightly. In some embodiments, the ring width D is 35mm. In this case, the efficiency of air intake and smoke extraction when oil fumes enter the air intake cavity 173 through the annular air inlet 180 is effectively ensured, and the problem of the annular air inlet 180 being too large and unsightly is effectively avoided.

[0055] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 A connecting portion 161 may be provided on the guide vane 160. The connecting portion 161 and the guide vane 160 can be formed into a separate structure by means of snap-fit ​​connection, bolt connection, etc., or they can be formed into an integral structure by means of welding, etc. A connecting mating portion 1732 may be provided on the cavity wall of the air inlet cavity 173. The connecting mating portion 1732 and the cavity wall of the air inlet cavity 173 can be formed into a separate structure by means of snap-fit ​​connection, bolt connection, etc., or they can be formed into an integral structure by means of welding, etc. The guide vane 160 can be detachably connected to the cavity wall of the air inlet cavity 173 through the connecting portion 161 and the connecting mating portion 1732. In this way, it is convenient to install the guide vane 160, and the guide vane 160 can be detachably connected to the cavity wall of the air inlet cavity 173, which is convenient for users to clean and replace the guide vane 160. Specifically, the connecting portion 161 and the connecting mating portion 1732 can be connected by means of snap-fit ​​connection, bolt connection, etc.

[0056] In some embodiments, the connecting portion 161 and the connecting mating portion 1732 can be configured as magnetic components. The connecting portion 161 and the connecting mating portion 1732 can be connected by magnetic attraction. In this way, the guide plate 160 is suspended and connected to the cavity wall of the air inlet cavity 173, which facilitates the installation and removal of the guide plate 160.

[0057] In some embodiments, the guide plate 160 may be provided with four connecting portions 161. The cavity wall of the air inlet chamber 173 may be provided with four connecting mating portions 1732. Two of the four connecting portions 161 may be spaced apart on the end of the guide plate 160 near the second smoke collection chamber 150, and the other two may be spaced apart on the end of the guide plate 160 away from the second smoke collection chamber 150. Two of the four connecting mating portions 1732 may be spaced apart on the end of the cavity wall of the air inlet chamber 173 near the second smoke collection chamber 150, and the other two may be spaced apart on the end of the cavity wall of the air inlet chamber 173 away from the second smoke collection chamber 150. This effectively ensures the stability of the connection between the guide plate 160 and the cavity wall of the air inlet chamber 173, preventing the guide plate 160 from detaching.

[0058] See also Figures 1 to 6 The front panel 120 may have a first plate 121 and a second plate 122. The first plate 121 may be opposite to the mounting plate 110. The second plate 122 may be connected to the upper end of the first plate 121. A first air inlet 171 may be connected to the first plate 121. A second air inlet 172 may be connected to the second plate 122. In this way, space can be fully utilized to make the air inlet cavity 173 as large as possible, thereby ensuring air intake efficiency and smoke extraction effect. Understandably, the first plate 121 and the second plate 122 may be at a certain angle. By respectively setting the first air inlet 171 and the second air inlet 172 on the first plate 121 and the second plate 122, the first air inlet 171 and the second air inlet 172 can be made as large as possible, thereby making the air inlet cavity 173 as large as possible, thereby ensuring air intake efficiency and smoke extraction effect. Specifically, the first plate 121 and the second plate 122 may be formed into an integral structure by bending or stamping processes. Of course, the first plate 121 and the second plate 122 can also be connected by snap-fit ​​or bolt to form a separate structure.

[0059] See also Figure 2 , Figure 4 , Figure 6 and Figure 7 The guide plate 160 may have a first guide portion 162 and a second guide portion 163. The second guide portion 163 may be connected to the upper end of the first guide portion 162. When the guide plate 160 is connected to the cavity wall of the air inlet chamber 173, the first guide portion 162 may be flush with the first plate 121, and the second guide portion 163 may be flush with the second plate 122. In this way, the aesthetics of the whole machine are effectively guaranteed, and the problem of increased thickness caused by the guide plate 160 protruding from the front plate 120 is avoided. Specifically, the first guide portion 162 and the second guide portion 163 may be formed into an integral structure by bending or stamping processes. Of course, the first guide portion 162 and the second guide portion 163 may also be formed into a separate structure by snap-fit ​​connection, bolt connection, or other methods.

[0060] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The first air inlet 171 may have a first top wall 1711. A first air inlet hole 1701 may be disposed on the first top wall 1711. The projection of the first guide portion 162 toward the first top wall 1711 may cover at least a portion of the first air inlet hole 1701. Thus, the first guide portion 162 can shield the first air inlet hole 1701, ensuring the overall aesthetics of the device. Specifically, the first air inlet hole 1701 may be constructed as a plurality of mesh holes arranged in rows and columns.

[0061] In some embodiments, two connecting parts 1732 may be provided at intervals on the end of the first top wall 1711 away from the second smoke collection chamber 150. When the guide plate 160 is disposed on the cavity wall of the air inlet chamber 173, the connecting part 161 and the connecting part 1732 located on the first top wall 1711 are connected and can be located inside the first air inlet 171 so that the first guide part 162 can be flush with the first plate 121.

[0062] See again Figure 1 , Figure 3 , Figure 4 and Figure 5 The second air inlet 172 may have a second top wall 1721. A second air inlet 1702 may be disposed on the second top wall 1721. The projection of the second air guide 163 toward the second top wall 1721 may cover at least a portion of the second air inlet 1702. Thus, the second air guide 163 can shield the second air inlet 1702, ensuring the overall aesthetics of the device. Specifically, the second air inlet 1702 may be constructed as a plurality of mesh holes arranged in rows and columns.

[0063] In some embodiments, two connecting parts 1732 may be provided at intervals on one end of the second top wall 1721 near the second smoke collection chamber 150. When the guide plate 160 is disposed on the cavity wall of the air inlet chamber 173, the connecting part 161 and the connecting part 1732 located on the second top wall 1721 are connected and can be located inside the second air inlet 172, so that the second guide part 163 can be flush with the second plate 122.

[0064] See also Figure 2 , Figure 4 , Figure 6 and Figure 7 The first guide section 162 and the second guide section 163 may have an included angle α, where α > 90°. For example, the included angle α can be 95°, 112°, 120°, etc. Setting the included angle α within this range effectively avoids the problem of oil accumulation on the guide plate 160.

[0065] See also Figure 1 , Figure 5 and Figure 6 In the width direction of the first plate 121 (i.e. Figure 5 In the Y direction, the first air inlet 171 can have a first maximum width M1, where 60mm ≤ M1 ≤ 280mm. For example, the first maximum width M1 can be 60mm, 123mm, 280mm, etc. Setting the first maximum width M1 within this range effectively ensures the basic air inlet area, thereby ensuring air inlet efficiency and avoiding the problem of an excessively large air inlet cavity 173 causing aesthetic issues.

[0066] See also Figure 1 and Figure 5 The first air inlet 171 may have a first top wall 1711. A first air inlet 1701 may be disposed on the first top wall 1711. In the width direction of the first plate 121 (i.e....) Figure 5 In the Y direction, the first top wall 1711 can have a first width W1, where W1 = 0.6M1. When the first maximum width M1 and the first width W1 have this relationship, the air intake area is effectively guaranteed, thereby ensuring the air intake efficiency.

[0067] See also Figure 1 , Figure 5 and Figure 6 In the width direction of the second plate 122 (i.e. Figure 5 In the Y direction, the second air inlet 172 can have a second maximum width M2, where 60mm ≤ M2 ≤ 280mm. For example, the second maximum width M2 can be 60mm, 123mm, 280mm, etc. Setting the second maximum width M2 within this range effectively ensures the basic air inlet area, thereby ensuring air inlet efficiency and avoiding the problem of an excessively large air inlet cavity 173 causing aesthetic issues.

[0068] See also Figure 1 and Figure 5 The second air inlet 172 may have a second top wall 1721. A second air inlet 1702 may be disposed on the second top wall 1721. In the width direction of the second plate 122 (i.e....) Figure 5 In the Y direction (of the structure), the second top wall 1721 can have a second width W2, where W2 = 0.6M2. When the second maximum width M2 and the second width W2 have this relationship, the air intake area is effectively guaranteed, thereby ensuring the air intake efficiency.

[0069] See also Figure 1 , Figure 5 and Figure 6 In the length direction of the front panel 120 (i.e. Figure 5In the X direction (as shown in the image), the air inlet cavity 173 can have a length L, where L ≤ 460mm. For example, the length L can be 460mm, 415mm, 386mm, etc. Setting the length L within this range effectively ensures the basic air inlet area, thereby ensuring air inlet efficiency, and avoids the problem of the air inlet cavity 173 being too large and affecting the overall appearance of the machine.

[0070] See also Figure 1 and Figure 5 The first air inlet 171 may have a first top wall 1711. A first air inlet 1701 may be disposed on the first top wall 1711. In the length direction of the front panel 120 (i.e....) Figure 5 In the X direction (as shown in the diagram), the first top wall 1711 can have a first length L1, where L1 = 0.75L. This relationship between length L and the first length L1 effectively ensures the air intake area, thereby guaranteeing air intake efficiency and avoiding the aesthetic problem of an excessively large annular air intake 180. Understandably, the larger the first top wall 1711, the more first air intake holes 1701 can be opened on it, and the larger the air intake area.

[0071] See again Figure 1 and Figure 5 The second air inlet 172 may have a second top wall 1721. A second air inlet 1702 may be disposed on the second top wall 1721. In the length direction of the front panel 120 (i.e....) Figure 5 In the X direction (as shown in the image), the second top wall 1721 can have a second length L2, where L2 = 0.75L. This relationship between length L and second length L2 effectively ensures the air intake area, thereby guaranteeing air intake efficiency and avoiding the aesthetic problem of an excessively large annular air intake 180. Understandably, the larger the second top wall 1721, the more air intake holes can be opened on it, and the larger the air intake area becomes.

[0072] For example, the first top wall 1711 and the second top wall 1721 can have a total area, i.e., an openable area. The larger the openable area, the more first air inlets 1701 and second air inlets 1702 can be opened on the first top wall 1711 and the second top wall 1721, and the larger the air intake area. Let the openable area be S1, S1 = W1 × L1 + W2 × L2 (i.e., the area of ​​the first top wall 1711 + the area of ​​the second top wall 1721). Since L1 = 0.75L and L2 = 0.75L, we get L1 = L2. Therefore, S1 = W1 × L1 + W2 × L2 can be simplified to S1 = (W1 + W2) × L1.

[0073] For example, 2 / 3 of the openable area S1 can be perforated, and the air inlet area can be set as S2, that is, S2 = 2 / 3S1 (that is, the total area of ​​the first air inlet 1701 and the second air inlet 1702). At this time, the air inlet area S2 can be as large as possible, while ensuring the structural strength of the first top wall 1711 and the second top wall 1721.

[0074] For example, the annular air inlet 180 can have a basic air inlet area. The basic air inlet area is set as S3, where S3 = 2(L-2D)×D + 2(M1+M2)×D.

[0075] In some embodiments, the length L is 460mm, the first length L1 is 345mm (i.e., 0.75L), the second length L2 is 345mm (i.e., 0.75L), the first maximum width M1 is 280mm, the first width W1 is 168mm (i.e., 0.6M1), the second maximum width M2 is 280mm, the second width W2 is 168mm (i.e., 0.6M2), and the ring width D is 35mm. Substituting these values, we get: S2 = 69552mm, S3 = 66500mm, therefore S3 > 0.85S2. Thus, the basic air intake area S3 is greater than 85% of the air intake area S2, ensuring smooth airflow, effectively guaranteeing air intake efficiency, and reducing the load.

[0076] See also Figures 1 to 4 The end of the second plate 122 furthest from the first plate 121 may have an upper extension 123. The upper extension 123 may have a height H, where H ≤ 35mm. For example, the height H can be 35mm, 27mm, 24mm, etc. Setting the height H within this range effectively reduces the thickness of the second smoke collection chamber 150, reduces the space occupied by the second smoke collection chamber 150, and makes the whole machine thinner. Specifically, the upper extension 123 can be integrated with the front plate 120 through bending or stamping processes. Of course, the upper extension 123 can also be separated from the front plate 120 through snap-fit ​​connections, bolt connections, etc.

[0077] See again Figures 1 to 4 The end of the first plate 121 away from the second plate 122 can have a distance S between it and the mounting plate 110, where S ≤ 35 mm. For example, the distance S can be 35 mm, 27 mm, 24 mm, etc. Setting the distance S within this range effectively reduces the thickness of the first smoke collection chamber 140, reduces the space occupied by the first smoke collection chamber 140, and makes the whole machine thinner.

[0078] According to another aspect of this utility model, a range hood 1 is provided, which may include a fan assembly 20 and a smoke collection assembly 10 as described above. The smoke collection assembly 10 may be disposed below the fan assembly 20. The air inlet chamber 173 is directly below the fan assembly 20, which makes the air intake smoother, improves the air intake efficiency, and reduces the load. Moreover, since the smoke collection assembly 10 described above has the above-mentioned beneficial effects, the range hood 1 including the smoke collection assembly 10 described above also has the above-mentioned beneficial effects, which will not be elaborated further here.
