In the prior art, a range hood includes a housing and a fume hood connected to the bottom of the housing. A fan is provided in the housing and an oil net is provided in the fume hood. When the range hood is working, the fan rotates to generate suction, so that the oil fume is first filtered through the oil net in the fume hood, then enters the housing, and finally is discharged to the outside through the external exhaust pipe connected to the housing, thereby purifying the indoor air. However, the fan generates noise when rotating and the smoke generates noise when passing through the oil net, resulting in a relatively high noise level when the range hood is in operation, and a poor user experience.

Based on this, an embodiment of the present application provides a range hood, which includes a box body and a smoke hood, wherein the smoke hood is connected to the bottom of the box body, and at least one inner wall of the box body and the smoke hood are provided with a fixing component, wherein the fixing component includes a fixing plate and a claw, and the fixing plate is connected to the box body or the smoke hood, and is connected to a sound-absorbing component through the claw, so that the sound-absorbing component is firmly set in the box body or the smoke hood. When the range hood is running, the sound-absorbing component in the box body can absorb the noise generated by the operation of the fan, and the sound-absorbing component in the smoke hood can absorb the noise generated when the smoke flows through the smoke hood, thereby reducing the noise generated when the range hood is running and improving the user experience.

The following describes the embodiments of the present utility model in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of the structure of the range hood in an embodiment of the present application; Fig. 2 is a cross-sectional view taken along the A-A direction in Fig. 1; and Fig. 3 is an enlarged view of part B in Fig. 2.

The present embodiment provides a range hood, as shown in Figures 1 to 3, the range hood includes a housing 100 and a smoke hood 200 connected to the bottom of the housing 100, a fixing assembly 300 is provided on at least one inner wall of the housing 100 and in the smoke hood 200, the fixing assembly 300 includes a fixing plate 310 and a claw 320 connected to the fixing plate 310, the fixing plate 310 is connected to the housing 100 or the smoke hood 200, and is connected to a sound absorbing component 400 via the claw 320.

Specifically, the box body 100 may be a rectangular parallelepiped structure extending in the vertical direction, and the box body 100 has a cavity inside, a fan (not shown in the figure) is installed in the cavity, the inlet of the fan is connected to the inside of the box body 100, an air outlet 101 is arranged at the top of the box body 100, and the outlet of the fan is connected to the air outlet 101. The smoke hood 200 is connected to the bottom of the box body 100, and the smoke hood 200 may be a rectangular parallelepiped structure extending in the horizontal direction, the bottom of the smoke hood 200 is provided with an air inlet 201, the top of the smoke hood 200 has a connecting port, the bottom end opening of the box body 100 is arranged and plugged into the connecting port, so that the smoke hood 200 is connected to the inside of the box body 100. When the range hood is working, negative pressure is generated in the box 100 through the rotation of the fan, so that smoke can be absorbed through the air inlet 201 at the bottom of the smoke hood 200. After entering the box 100, the smoke is sucked into the fan and discharged from the air outlet 101 to achieve the purpose of purifying indoor air.

By installing the sound absorbing member 400 on one or more inner walls of the housing 100, the sound absorbing member 400 can be used to absorb the noise generated when the fan is running. By installing the sound absorbing member 400 in the smoke collecting hood 200, the sound absorbing member 400 can be used to absorb the noise generated when the smoke passes through the inside of the smoke collecting hood 200. In this way, the noise transmitted to the room when the range hood is running can be greatly reduced, providing a more comfortable use environment for users.

The number and installation positions of the sound absorbing members 400 in the box body 100 may be set according to the specific structure of the box body 100 .

Exemplarily, the box 100 may include a first side panel 110 and a plurality of second side panels 120, the first side panel 110 and the plurality of second side panels 120 are together arranged to form the box 100, the first side panel 110 is used to be fixed on the wall, and a sound absorbing member 400 may be provided on the inner wall of each second side panel 120. The number of the second side panels 120 may be set according to the specific structure of the box 100, for example, three second side panels 120 may be provided, so that the box 100 having a rectangular structure is surrounded by the first side panel 110 and the three second side panels 120.

Since the range hood is generally mounted on a wall, a mounting structure can be provided on the first side plate 110 of the housing 100 so that the first side plate 110 of the housing 100 is connected to the wall, thereby achieving the mounting and fixing of the range hood. Since the first side wall is disposed against the wall, the noise generated when the fan is running will not be transmitted to the room through the first side plate 110, and a sound absorbing member 400 is disposed on the inner side of each second side plate 120, so that multiple sound absorbing members 400 are disposed around multiple locations of the fan, and the multiple sound absorbing members 400 can absorb noise transmitted from more directions, thereby improving the noise reduction capability of the housing 100.

Likewise, the number and installation positions of the sound absorbing members 400 in the smoke collecting hood 200 may be set according to the specific structure of the smoke collecting hood 200 and its interior.

For example, in actual use, as shown in Figure 2, an oil guide plate 210, a support beam 220 and an oil net 230 are also provided in the smoke hood 200. The oil guide plate 210 and the support beam 220 are spaced apart on two opposite inner walls of the smoke hood 200, and the two ends of the oil net 230 are respectively connected between the oil guide plate 210 and the support beam 220, and the oil guide plate 210 and the oil net 230 are both inclined.

When the range hood is working, the smoke is sucked into the smoke hood 200 through the air inlet 201, and then enters the box body 100 after being filtered by the oil net 230. When the smoke passes through the oil net 230, the flow rate is accelerated due to the reduction in ventilation area, which causes the smoke to generate greater noise when passing through the oil net 230, and transmits the noise into the room through the oil guide plate 210 and the side wall of the smoke hood 200.

Therefore, the sound absorbing member 400 can be set on the oil guide plate 210. The oil guide plate 210 provides an installation position for the sound absorbing member 400, so that the sound absorbing member 400 is closer to the oil net 230, and the noise will also be absorbed by the sound absorbing member 400 when it is transmitted outward through the oil guide plate 210, thereby being able to more effectively absorb the noise in the smoke hood 200 and improve the noise reduction effect of the sound absorbing member 400 on the smoke hood 200.

It can be understood that the sound absorbing member 400 is installed in the box body 100 and the smoke hood 200 through the fixing assembly 300. When assembling, the fixing plate 310 can be first connected to the second side plate 120 of the box body 100 and the oil guide plate 210 in the smoke hood 200, and then the sound absorbing member 400 can be connected to the fixing plate 310 through the claw 320 to achieve the connection and fixation of the sound absorbing member 400 with the second side plate 120 or the oil guide plate 210. On the one hand, it is convenient for the assembly of the sound absorbing member 400, and on the other hand, it can improve the stability of the sound absorbing member 400 in the box body 100 and the smoke hood 200, so as to avoid the sound absorbing member 400 falling off from the box body 100 or the smoke hood 200 during the oil smoke extraction operation and affecting the normal use of the range hood.

When the sound absorbing member 400 is installed in a large area, the sound absorbing member 400 can be fixed by multiple fixing components 300. For example, as shown in FIG1 , the sound absorbing member 400 installed on the second side plate 120 of the main box 100 has a large area, and two fixing components 300 spaced apart in the vertical direction can be provided, so that both the upper and lower ends of the sound absorbing member 400 are connected to the second side plate 120 through the fixing components 300, so as to improve the fixing effect of the sound absorbing member 400. When the sound absorbing member 400 is installed in a small area, the sound absorbing member 400 can be fixed by only one fixing component 300. For example, as shown in FIG2 , the area of the oil guide plate 210 is small, and the sound absorbing member 400 can be connected to the oil guide plate 210 through one fixing component 300.

The following will take the fixing assembly 300 disposed on the oil guide plate 210 as an example to further describe the specific structure of the fixing plate 310 and the claw 320 in the fixing assembly 300. It can be understood that the following description of the fixing assembly 300 is also applicable to the box body 100.

FIG. 4 is an exploded view of the internal structure of the range hood in the embodiment of the present application; FIG. 5 is an enlarged view of part C in FIG. 4 .

4 and 5 , the shape of the fixing plate 310 can be set based on the shape of the oil guide plate 210. For example, the fixing plate 310 can be rectangular. The extension direction of the fixing plate 310 is consistent with the extension direction of the oil guide plate 210. The number of claws 320 can be set according to the length of the fixing plate 310. For example, a plurality of claws 320 can be provided and spaced apart along the extension direction of the fixing plate 310. The plurality of claws 320 are used to improve the fixing effect of the sound absorbing member 400.

In some embodiments, the claw 320 may include a connecting portion 321 and a pressing portion 322, one end of the connecting portion 321 is connected to the fixing plate 310, and the pressing portion 322 is movably connected to the other end of the connecting portion 321. The sound absorbing member 400 is provided with a through hole 401, the connecting portion 321 may be inserted into the through hole 401, and the pressing portion 322 abuts against the surface of the sound absorbing member 400, so as to press the sound absorbing member 400 against the fixing plate 310.

Among them, the pressing part 322 can be rotated relative to the connecting part 321. At this time, the pressing part 322 and the connecting part 321 can be inserted into the through hole 401. Before connecting the sound absorbing member 400, the pressing part 322 and the connecting part 321 are placed on the same straight line. After the pressing part 322 passes through the through hole 401, the through hole 401 is sleeved on the connecting part 321. At the same time, one side surface of the sound absorbing member 400 is fitted with the surface of the fixing plate 310. Then, the pressing part 322 is rotated relative to the connecting part 321 so that the pressing part 322 is pressed on the other side surface of the sound absorbing member 400 to press the sound absorbing member 400 tightly against the fixing plate 310.

Alternatively, the pressing portion 322 may also be detachably connected to the connecting portion 321 by adopting a plug-in structure or a snap-on structure. When connecting the sound absorbing member 400, the pressing portion 322 is first separated from the connecting portion 321, and the connecting portion 321 is inserted into the through hole 401. Then, the pressing portion 322 is connected to the connecting portion 321 so that the pressing portion 322 is pressed on the surface of the sound absorbing member 400 to fix the sound absorbing member 400 on the fixing plate 310.

Of course, the pressing portion 322 may also be movably connected to the connecting portion 321 in other ways as long as the sound absorbing member 400 can be fixed, which will not be listed one by one in this embodiment.

Furthermore, in some embodiments, when the pressing portion 322 is rotated relative to the connecting portion 321 to press the sound absorbing member 400 , the connecting portion 321 and the pressing portion 322 may also be integrally formed.

Specifically, the claw 320 can be made of metal or plastic with good plasticity, and the pressing portion 322 can pass through the through hole 401, so that the connecting portion 321 can be inserted into the through hole 401. After the pressing portion 322 passes through the through hole 401, the pressing portion 322 is manually pressed to bend to one side relative to the connecting portion 321 until the pressing portion 322 is pressed against the surface of the sound absorbing component 400, thereby achieving the pressing and fixing of the sound absorbing component 400.

The one-piece clamping claw 320 is not only easy to manufacture, but also easy to use, which can further improve assembly efficiency. In addition, the clamping claw 320 can also be integrally formed with the fixing plate 310. For example, when the clamping claw 320 and the fixing plate 310 are both made of metal, they can be directly processed and formed by a stamping process, which has the advantages of easy processing and production and low cost.

It is understandable that the fixing plate 310 can be fixed to the oil guide plate 210 by bonding, welding, screw connection or rivet connection, which is not specifically limited in this embodiment. When the fixing plate 310 is riveted to the oil guide plate 210 by rivets, the oil guide plate 210 can also be provided with a rivet hole 313 for the rivet to pass through and connect to the oil guide plate 210.

Among them, the number of rivet holes 313 is not specifically limited, and it can be set according to the length of the fixing plate 310. For example, three rivet holes 313 can be provided and spaced apart along the extension direction of the fixing plate 310, so that the fixing plate 310 is riveted to the oil guide plate 210 by multiple rivets.

Furthermore, when the rivet hole 313 is opened on the fixing plate 310, a protrusion 311 can also be set on the fixing plate 310, and a groove 312 is set on the protrusion 311, and the rivet hole 313 is set at the bottom of the groove 312, and the rivet is embedded in the groove 312 and flush with the surface of the protrusion 311.

The protrusion 311 can be formed by stamping on the fixing plate 310, and the recessed groove 312 and the rivet hole 313 can be directly formed on the protrusion 311 when processing the protrusion 311. The diameter of the recessed groove 312 is larger than the diameter of the rivet hole 313, and the depth of the recessed groove 312 is not less than the thickness of the head of the rivet. When the rivet is inserted into the rivet hole 313, the recessed groove 312 can be used to limit the head of the rivet, and the head of the rivet is flush with the surface of the protrusion 311. When the sound absorbing member 400 is connected, the sound absorbing member 400 can be completely attached to the surface of the protrusion 311, and it is not easy to have a gap between the sound absorbing member 400 and the sound absorbing member 400, so as to ensure that the sound absorbing effect of the sound absorbing member 400 is good.

After the protrusion 311 is set on the fixed plate 310, the claw 320 can be connected to the two ends of the fixed plate 310, or it can be set on the protrusion 311. When there are multiple claws 320, the claws 320 can also be set at both ends of the fixed plate 310 and on the protrusion 311. There is no specific limitation on this in this embodiment.

In addition, in some embodiments, the portion of the sound absorbing member 400 located outside the fixing plate 310 may also be provided with an adhesive layer, and connected to the box body 100 or the smoke collecting hood 200 through the adhesive layer.

Specifically, the adhesive layer is arranged on the surface of the sound absorbing member 400 facing the fixed plate 310, and the size of the adhesive layer is consistent with the surface area of the sound absorbing member 400 located on the outer side of the fixed plate 310, that is, the adhesive layer is arranged at the portion where the sound absorbing member 400 contacts the second side plate 120 or the oil guide plate 210, so that the portion of the sound absorbing member 400 that is not in contact with the fixed plate 310 is adhered to the second side plate 120 or the oil guide plate 210.

The adhesive layer may be a double-sided tape pre-set on the surface of the sound absorbing member 400, or an adhesive material may be coated on the surface of the sound absorbing member 400 before assembly, so that during the assembly process, the sound absorbing member 400 can be pre-fixed on the second side panel 120 or the oil guide plate 210 through the adhesive layer, and then the sound absorbing member 400 can be fixed using the fixing assembly 300, which not only facilitates the assembly of the sound absorbing member 400, but also ensures that the sound absorbing member 400 is completely attached to the second side panel 120 or the oil guide plate 210, thereby ensuring that the sound absorbing member 400 has a better sound absorption effect.

The sound absorbing member 400 in this embodiment can be sound absorbing cotton, which is a porous material that can effectively absorb sound waves and has good noise reduction capability. The sound absorbing cotton is light in weight and will not increase the overall weight of the range hood too much. Of course, the sound absorbing member 400 can also be made of materials such as mineral wool sound absorbing panels, polyurethane foam plastics, polystyrene foam plastics or aluminum-magnesium alloy sound absorbing panels, which can be selected according to the internal structure of the range hood and actual use requirements, and will not be listed one by one in this embodiment.

In summary, the range hood provided in the present embodiment arranges sound absorbing members 400 on each second side panel 120 of the case 100, so that multiple sound absorbing members 400 surround the fan to absorb the noise generated when the fan is running. By arranging the sound absorbing member 400 on the oil guide plate 210 of the smoke hood 200, the noise generated when the smoke passes through the oil net 230 can be absorbed, thereby greatly reducing the noise level transmitted into the room during the operation of the range hood and improving the user experience.

In addition, the sound absorbing member 400 is arranged in the box body 100 or the smoke hood 200 through the fixing component 300. The fixing component 300 includes a fixing plate 310 and a claw 320, and a connecting hole is provided on the sound absorbing member 400. The claw 320 is deformed after passing through the connecting hole, and the sound absorbing member 400 is pressed onto the surface of the fixing plate 310 to realize the assembly of the sound absorbing member 400. This not only improves the assembly efficiency of the sound absorbing member 400, but also makes the sound absorbing member 400 more firmly on the second side plate 120 and the oil guide plate 210, and is not easy to shake and fall off, thereby ensuring the stable operation of the range hood.
