Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a smoke collecting component and a range hood. Background Art

[0002] The range hood uses a motor to drive the impeller to rotate at high speed, forming a negative pressure area near the smoke collection chamber, sucking the smoke into the body and exhausting it outdoors.

[0003] Some existing range hoods include an upper smoke collecting chamber and a lower smoke collecting chamber, and the upper smoke collecting chamber and the lower smoke collecting chamber are connected to form a 7 shape. During the operation of the 7-shaped smoke collecting chamber, since the angle between the upper smoke collecting chamber and the lower smoke collecting chamber is close to 90 degrees, a large amount of oil smoke can easily diffuse through the cavity wall of the upper smoke collecting chamber, causing the oil smoke to escape, resulting in the oil smoke not being fully absorbed, and achieving a good smoking effect. 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, and the technical solution is as follows.

[0005] The smoke collecting assembly includes a first main body and a second main body. The first main body encloses a first smoke collecting chamber, and the second main body encloses a second smoke collecting chamber connected to the first smoke collecting chamber. The second smoke collecting chamber is formed above the first smoke collecting chamber and protrudes outward relative to the first smoke collecting chamber. The second main body has a top body and a bottom body. The bottom body is connected to a stretching body. The stretching body is stretched from the bottom body toward the top body to form a stretching chamber. The stretching body is provided with a first air inlet.

[0006] The smoke collecting assembly of the present invention forms a second smoke collecting chamber above the first smoke collecting chamber through the second main body, and a stretching body is connected to the second main body to form a stretching chamber through the stretching body. The stretching chamber is connected to the outside through the first air inlet. When the oil smoke rises to the second main body, it can enter the stretching chamber and then enter the second smoke collecting chamber through the first air inlet, avoiding the problem of oil smoke spreading through the second main body (i.e., the cavity wall of the smoke collecting chamber) and causing the oil smoke to escape. The oil smoke can be fully absorbed, thereby improving the smoke collection effect.

[0007] For example, the stretching body includes a top wall and side walls, with the top wall being spaced apart from the bottom body and connected to the bottom body via the side walls. The first air inlet is provided on the side wall. This allows the oil smoke to rise to the second body and be blocked by the top and side walls from accumulating in the stretching cavity. The oil smoke accumulated in the stretching cavity then enters the second smoke collection cavity through the first air inlet on the side wall. This not only prevents the oil smoke from spreading but also quickly guides the oil smoke into the second smoke collection cavity, further enhancing smoke collection efficiency.

[0008] For example, the angle α formed between the side wall and the bottom body is 35°≤α≤55°. When the angle α is set within this range, the oil smoke can be well guided to gather in the stretching cavity and then enter the second smoke collecting cavity through the first air inlet.

[0009] For example, the sidewall includes a first sidewall and a second sidewall, the first sidewall being disposed opposite the second sidewall, with the first sidewall being closer to the first smoke collection chamber in a direction perpendicular to the mounting surface, and the first air inlet being disposed on the first sidewall. This allows oil smoke to quickly enter the second smoke collection chamber through the stretching chamber, thereby improving smoke collection efficiency.

[0010] For example, a second air inlet is provided on one end of the first body away from the second body, so that the smoke can be absorbed by the second air inlet first during its rising process, thereby improving the smoke collection effect.

[0011] For example, the height H of the second air inlet is 80 mm to 120 mm. Setting the height H of the second air inlet within this range can increase the wind speed of the second air inlet and absorb most of the oil smoke.

[0012] For example, the first body has a front plate and a back plate, the back plate is arranged on the mounting surface, the front plate is inclined relative to the back plate, and the second air inlet is arranged on the front plate. In this way, the front plate is inclined relative to the mounting surface to guide the oil smoke and increase the smoke collection speed.

[0013] For example, a third air inlet is provided at one end of the first body where it connects to the bottom body. This arrangement allows the bottom body and the first body to form a smoke-collecting area, trapping diffused oil smoke within the area and effectively preventing it from escaping. Furthermore, the smoke trapped within the area can be rapidly absorbed through the third air inlet, improving the fume absorption effect. Furthermore, the third air inlet can be conveniently formed by providing it on the first body.

[0014] For example, the first body has a first side proximate to the second smoke collection chamber, and the bottom body has a second side proximate to the first smoke collection chamber. A gap is defined between the first and second sides, forming the third air inlet. With this arrangement, the bottom body and the first body form a smoke-collecting area, trapping diffused oil smoke within the area and effectively preventing it from escaping. Furthermore, the smoke trapped within the area can be rapidly absorbed through the third air inlet, enhancing the fume absorption effect. Furthermore, by providing a gap between the first body and the bottom body, the third air inlet can be formed through the gap, facilitating the formation of the third air inlet.

[0015] For example, the height L of the gap is 10 mm to 40 mm. When the height L of the gap is set within this range, the oil smoke outside can be radiated over a large area and pulled to absorb the oil smoke.

[0016] According to another aspect of the present invention, a range hood is provided, comprising a fan assembly and the aforementioned smoke collection assembly, wherein the smoke collection assembly is disposed below the fan assembly. Since the aforementioned smoke collection assembly has the aforementioned beneficial effects, a range hood including the aforementioned smoke collection assembly also has the aforementioned beneficial effects, which will not be further elaborated herein.

[0017] The Summary of the Utility Model introduces a series of simplified concepts, which will be further described in detail in the Detailed Description of the Utility Model. This Summary of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0027] In the following description, numerous specific details are provided for a thorough understanding of the present application. One of ordinary skill in the art will recognize, however, that the application can be practiced without one or more of these specific details. In other instances, well-known structures and processes have not been described in order not to obscure the application.

[0028] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0029] The embodiments of the present application provide a smoke collecting assembly. The smoke collecting assembly provided by the present application can be applied to a range hood. Hereinafter, a smoke collecting assembly according to an embodiment of the present application will be introduced in detail in combination with the drawings.

[0030] In combination with the drawings, Figures 1 to 5 The smoke collecting assembly 10 can include a first body 110 and a second body 120. The first body 110 can enclose a first smoke collecting cavity 111. The second body 120 can enclose a second smoke collecting cavity 121 which is in communication with the first smoke collecting cavity 111. The second smoke collecting cavity 121 can be formed above the first smoke collecting cavity 111 and protrude outward relative to the first smoke collecting cavity 111. It should be understood that "outward" here is closer to the operator and is away from the mounting surface. The second body 120 can have a top body 122 and a bottom body 123. The bottom body 123 can be connected with a stretching body 124. The stretching body 124 can be stretched from the bottom body 123 to the top body 122 to form a stretching cavity 125. The stretching body 124 can be provided with a first air inlet 126.

[0031] The smoke collecting assembly 10 of the utility model, since the second main body 120 forms the second smoke collecting cavity 121 above the first smoke collecting cavity 111, and the second main body 120 is connected with the stretching body 124, the stretching cavity 125 is formed in the stretching body 124, the stretching cavity 125 is communicated with the outside through the first air inlet 126, when the oil fume rises to the second main body 120, can enter the stretching cavity 125 and then enter the second smoke collecting cavity 121 through the first air inlet 126, avoids the problem that the oil fume diffuses through the second main body 120 (the cavity wall of the second smoke collecting cavity 121), causes the oil fume to escape, and the oil fume can be fully absorbed, thereby improving the smoke collecting effect.

[0032] It should be noted that the mounting surface can be a wall, a cabinet wall, etc. Specifically, in combination with the description of the mounting surface in Figure 1 、 Figure 4 and Figure 5 , the mounting surface corresponds to the surface where the back plate 114 is located, and the stretching cavity 125 can be located in the front 1 / 3 of the direction away from the mounting surface of the bottom body 123. In this way, the problem that the oil fume diffuses through the cavity wall of the second smoke collecting cavity 121 and causes the oil fume to escape can be effectively avoided.

[0033] In combination with the description of the stretching body 124 in Figure 1 、 Figure 4 and Figure 5 , the stretching body 124 can have a top wall 1241 and a side wall 1242. The top wall 1241 can be connected with the bottom body 123 through the side wall 1242 and away from the bottom body 123. The first air inlet 126 can be arranged on the side wall 1242. In this way, when the oil fume rises to the second main body 120, the oil fume can be blocked in the stretching cavity 125 through the top wall 1241 and the side wall 1242, and the oil fume accumulated in the stretching cavity 125 enters the second smoke collecting cavity 121 through the first air inlet 126 on the side wall 1242. In this way, not only is the diffusion of the oil fume avoided, but also the oil fume can be quickly guided into the second smoke collecting cavity 121, further improving the smoke collecting effect. Specifically, the stretching body 124 can be stretched to form through the bottom body 123, and the stretching body 124 can be connected with the bottom body 123 into an integrated structure through integral molding, welding, etc. Of course, the stretching body 124 can also be connected with the bottom body 123 into a split structure through screw bolt connection, buckle connection, etc. At this time, the user can disassemble and assemble the stretching body 124 alone, so as to facilitate the user to clean and maintain the stretching body 124.

[0034] In combination with the description of the stretching body 124 in Figure 1 and Figure 5, an angle α can be formed between the side wall 1242 and the bottom body 123, 35°≤α≤55°. For example, the angle α can be 35°, 45°, 50°, etc. When the angle α is set within this range, the oil smoke can be well guided to gather in the stretching cavity 125, and then enter the second smoke collecting cavity 121 through the first air inlet 126. In one embodiment of the present invention, the angle α is 45°. At this time, the oil smoke can be effectively guided to gather in the stretching cavity 125, and then enter the second smoke collecting cavity 121 through the first air inlet 126.

[0035] Again, refer to Figure 1 and Figure 5 , the side wall 1242 may include a first side wall 1242a and a second side wall 1242b. The first side wall 1242a and the second side wall 1242b may be arranged opposite to each other. In the direction perpendicular to the installation surface, the first side wall 1242a may be closer to the first smoke collecting chamber 111. The first air inlet 126 may be provided on the first side wall 1242a. The first air inlet 126 may be a plurality of mesh holes provided on the first side wall 1242a, or a long strip hole provided on the first side wall 1242a. In this way, the oil smoke can quickly enter the second smoke collecting chamber 121 through the stretching chamber 125, thereby improving the smoke collection effect. In an embodiment not shown in the figure, the first air inlet 126 may also be provided on the second side wall 1242b. In this way, the problem of oil smoke diffusing through the cavity wall of the second smoke collecting chamber 121 and causing the oil smoke to escape is avoided.

[0036] See also Figure 1 、 Figure 2 and Figure 5 A second air inlet 112 may be provided on one end of the first body 110 away from the second body 120. In this way, the smoke can be first absorbed by the second air inlet 112 during the rising process, thereby improving the smoke collection effect.

[0037] See also Figures 1 to 5 The height H of the second air inlet 112 can be 80 mm to 120 mm. For example, the height H can be 80 mm, 100 mm, 120 mm, etc. Setting the height H of the second air inlet 112 within this range can increase the wind speed of the second air inlet 112 and absorb most of the oil smoke. In one embodiment of the present invention, the height H is 100 mm. In this case, the wind speed of the second air inlet 112 can be effectively increased, absorbing most of the oil smoke.

[0038] Again, refer to Figures 1 to 5The first main body 110 may have a front plate 113 and a back plate 114. The back plate 114 may be arranged on the mounting surface. The front plate 113 may be tilted relative to the back plate 114. The second air inlet 112 may be arranged on the front plate 113. In this way, the front plate 113 is tilted relative to the mounting surface, which can guide the oil smoke to increase the smoke collection speed. Specifically, an inclined plate 116 is connected below the back plate 114, which is tilted away from the mounting surface, so as to guide the oil stains to the oil cup 30 below. The height H of the second air inlet 112 is the projected height on the front plate 113.

[0039] In an embodiment not shown in the figures, a third air inlet 131 may be provided on one end of the first body 110 connected to the bottom body 123. Since the bottom body 123 and the first body 110 form a smoke gathering area, the diffused oil smoke is trapped in the smoke gathering area, effectively preventing the oil smoke from escaping. At the same time, the oil smoke trapped in the smoke gathering area can be quickly absorbed through the third air inlet 131, thereby improving the oil smoke absorption effect. And the formation of the third air inlet 131 can be facilitated by providing the third air inlet 131 on the first body 110. Specifically, the third air inlet 131 can be a plurality of mesh holes opened on one end of the front plate 113 close to the bottom body 123, or it can be a long strip hole opened on one end of the front plate 113 close to the bottom body 123.

[0040] See also Figures 1 to 5 , the first main body 110 may have a first side 115 close to the second smoke collecting chamber 121. The bottom body 123 may have a second side 1231 close to the first smoke collecting chamber 111. A gap 130 may be provided between the first side 115 and the second side 1231. The gap 130 may form a third air inlet 131. Since the bottom body 123 and the first main body 110 form a smoke collecting area, the diffused oil smoke is trapped in the smoke collecting area, effectively preventing the oil smoke from escaping. At the same time, the oil smoke trapped in the smoke collecting area can be quickly absorbed through the third air inlet 131, thereby improving the oil smoke absorption effect. And by providing a gap 130 between the first main body 110 and the bottom body 123, the third air inlet 131 can be formed through the gap 130, which facilitates the formation of the third air inlet 131. Specifically, the first side 115 may be provided on one end of the front plate 113 close to the second smoke collecting chamber 121.

[0041] See also Figures 1 to 4 The height L of gap 130 can be between 10 mm and 40 mm. For example, the height L can be 10 mm, 25 mm, 40 mm, etc. When the height L of gap 130 is set within this range, the oil smoke outside can be radiated and pulled to absorb the oil smoke over a large area. In one embodiment of the present invention, the height L is 25 mm. In this case, the oil smoke outside can be effectively radiated and pulled to absorb the oil smoke over a large area.

[0042] According to another aspect of the present invention, a range hood 1 is provided. Figure 4 and Figure 5 As shown, the range hood 1 may include a fan assembly 20 and the aforementioned smoke collection assembly 10, which may be disposed below the fan assembly 20. Since the smoke collection assembly 10 of the aforementioned embodiment has the aforementioned beneficial effects, the range hood 1 including the aforementioned smoke collection assembly 10 also has the aforementioned beneficial effects, which will not be described in detail here.

[0043] See also Figures 1 to 5 The range hood 1 is provided with a smoke collecting component 10, and its smoke collecting process is as follows: during the cooking process, when there is less oil smoke, the rising speed of the oil smoke is slower, and the second air inlet 112 can fully absorb the oil smoke; when there is more oil smoke, the rising speed of the oil smoke is faster, and the second air inlet 112 can preliminarily absorb the oil smoke, but the second air inlet 112 alone cannot fully absorb the oil smoke, and the oil smoke that continues to rise along the front plate 113 can be absorbed by the third air inlet 131, and the oil smoke that diffuses outward through the cavity wall of the second smoke collecting chamber 121 can be absorbed by the first air inlet 126, thereby avoiding the problem of oil smoke diffusing through the cavity wall of the second smoke collecting chamber 121 and causing oil smoke to escape, achieving full absorption of the oil smoke and improving the smoke collection effect.
