Description

Technical Field

[0001] This application relates to the field of range hood technology, and more specifically to a silencer for a side-blowing range hood used along the street. Background Technology

[0002] The range hood uses a motor to drive the impeller to rotate at high speed, creating a negative pressure zone above the stove. This draws the fumes into the machine and then exhausts them outdoors through pipes and a check valve.

[0003] There is a street-side range hood with an exhaust duct 90, such as Figure 7 As shown, the exhaust duct 90 is mounted on the wall and faces the road. During operation, the gas that has filtered the oil fumes is discharged outward from the exhaust duct 90. However, since the exhaust duct 90 faces the road directly, the gas will blow directly on pedestrians when they pass by the store, reducing their experience. In addition, since no noise reduction device is installed on the exhaust duct, the sound emitted from the opening of the exhaust duct 90 is relatively loud, which will also affect the pedestrians' experience and their impression of the store.

[0004] Therefore, there is a demand for a silencer for street-side range hoods that provides exhaust gas that does not blow directly onto pedestrians and produces low noise. Utility Model Content

[0005] The main objective of this application is to provide a silencer for a side-blowing range hood installed on a street-facing range hood. The silencer includes a housing assembly comprising an air inlet, a circulation chamber, and an exhaust outlet. One cross-section of the circulation chamber is rectangular. The top and one side walls of the circulation chamber are closed. The air inlet is located on the bottom wall of the circulation chamber. The exhaust outlet is located on the other three side walls of the circulation chamber. A sound-absorbing component is installed inside the circulation chamber. By closing one side wall of the circulation chamber, the exhaust gas is prevented from directly blowing onto pedestrians. The sound-absorbing component inside the circulation chamber reduces the output noise.

[0006] Another objective of this application is to provide a muffler for a side-blowing range hood along the street, wherein the housing assembly includes a first bent member and a second bent member, the middle sections of the first bent member and the second bent member are both bent at 90°, both ends of the first bent member have multiple exhaust ports, one end of the second bent member has multiple exhaust ports, and the other end of the second bent member has no holes, and when the first bent member and the second bent member are spliced ​​together, a rectangular column with a through chamber is formed.

[0028] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0029] This is an illustration of a muffler for a side-blowing range hood used along the street. (Reference) Figures 1 to 6 A silencer for a side-blowing street-side range hood, according to a preferred embodiment of the present invention, is installed on the range hood and communicates with the air outlet of the range hood, and includes a housing assembly 10.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the housing assembly 10 includes an air inlet 101, a flow chamber 102, and an exhaust port 103. One cross-section of the flow chamber 102 is rectangular. The top wall and one side wall of the flow chamber 102 are closed. The air inlet 101 is located on the bottom wall of the flow chamber 102. The exhaust port 103 is provided on the other three side walls of the flow chamber 102. A sound-absorbing component (not shown in the figure) is provided inside the flow chamber 102.

[0031] It should be noted that the air inlet 101 is connected to the air outlet on the range hood. During use, the filtered gas flows into the circulation chamber 102 from the air inlet 101. It should be pointed out that during use, the housing assembly 10 is arranged vertically, and one side wall of the circulation chamber 102 faces the pedestrian, that is, the side away from the wall. The three side walls of the circulation chamber 102 are located on the two sides and the side close to the wall, respectively. After the gas flows into the circulation chamber 102, it is discharged from the exhaust ports 103 on the two sides and the back, achieving the advantage that the discharged gas does not blow directly towards the pedestrian. In addition, since the sound-absorbing component is provided in the circulation chamber 102, some noise is absorbed, so the overall sound emitted when the gas is discharged is relatively small. Pedestrians do not need to deliberately avoid the noise when passing by. Compared with the prior art, it has the advantages of not blowing the discharged gas directly towards pedestrians and low noise.

[0032] Furthermore, to form the housing assembly 10, as... Figure 3 and Figure 4 As shown, the housing assembly 10 includes a first bending member 104 and a second bending member 105. The middle sections of both the first bending member 104 and the second bending member 105 are bent at 90°. Both ends of the first bending member 104 have multiple exhaust ports 103. One end of the second bending member 105 has multiple exhaust ports 103, and the other end of the second bending member 105 has no holes. When the first bending member 104 and the second bending member 105 are spliced ​​together, a rectangular column with a through chamber is formed. It should be noted that the through chamber of the rectangular column is the flow chamber 102, and one end of the through chamber constitutes the air inlet 101. Since one end of the second bending member 105 has no holes, one side wall of the flow chamber 102 is sealed.

[0033] It should be noted that after the first bent part 104 and the second bent part 105 are spliced ​​together, the first bent part 104 and the second bent part 105 are fixedly connected by welding.

[0034] Furthermore, to achieve the sealing of the top wall of the flow cavity 102, such as Figure 1 As shown, the housing assembly 10 also includes a cover 106, such as Figure 5 As shown, the cover 106 has a cavity 1061, and the opening of the cavity 1061 has a first folded edge 1062. One end of the rectangular column formed by splicing the first bending member 104 and the second bending member 105 extends into the cavity 1061, and the first folded edge 1062 is attached to the first bending member 104 or the second bending member 105. Subsequently, the cover 106 is fixedly connected to the first bending member 104 and the second bending member 105 by welding.

[0035] Furthermore, to provide conditions for placing the sound-absorbing element, such as... Figure 2 and Figure 4 As shown, both the first bending member 104 and the second bending member 105 have a second folded edge 1041 on the side opposite to the cover body 106.

[0036] Furthermore, the silencer for the side-blowing street-side range hood includes several concave strips, each with several through holes. The concave strips are disposed within the flow cavity 102 and connected to the housing assembly 10 by welding. The sound-absorbing element is disposed within the concave strips.

[0037] It should be noted that the preferred material for the sound-absorbing component is sound-absorbing cotton, as shown in the reference. Figure 5 Each of the concave strips has a recessed cavity to facilitate the placement of the sound-absorbing element.

[0038] Specifically, such as Figure 5 and Figure 6 As shown, the concave strip includes horizontal concave strips 1071 and vertical concave strips 1072. The vertical concave strips 1072 are vertically arranged at the four corners of the concave cavity 1061. Several horizontal concave strips 1071 are horizontally arranged between the vertical concave strips 1072 at both ends of the exhaust port 103. Each exhaust port 103 has horizontal concave strips 1071 on both sides. In this embodiment, since each surface of the housing assembly 10 with the exhaust port 103 has three exhaust ports 103, four horizontal concave strips 1071 are provided on the side of each surface with the exhaust port 103 closest to the flow cavity 102.

[0039] In addition, such as Figure 5 and Figure 6 As shown, the concave strip also includes two wide concave strips 1073, which are directly opposite one side wall of the cover 106 and the flow cavity 102. It should be noted that the two wide concave strips 1073 are respectively directly opposite the end of the cover 106 and the second bending member 105 without holes.

[0040] Furthermore, since the silencer used in the side-blowing street-facing range hood is located outdoors, to prevent the sound-absorbing components from getting wet from rain, such as... Figure 4 As shown, both the first bending member 104 and the second bending member 105 have a plurality of sloping eaves 1042 at one end of the vent 103, and each vent 103 has an inclined eave 1042 along its upper edge. When rainwater comes into contact with the sloping eave 1042, it slides down along the sloping eave 1042.

[0041] In summary, the muffler for a side-blowing street-facing range hood, based on the embodiments of this application, is explained, providing advantages such as the exhaust gas not blowing directly onto pedestrians and low noise.

[0042] It is worth mentioning that, in this embodiment, the silencer for the side-blowing street-facing range hood has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the silencer for the side-blowing street-facing range hood provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
