Description

Technical Field

[0001] The utility model relates to the technical field of oil fume treatment devices, in particular to an oil fume adsorption and noise reduction component and a range hood. Background Technique

[0002] During the use of a range hood, the noise is relatively large. Therefore, in order to achieve the noise reduction effect, sound-absorbing cotton is usually installed on the inner wall of the smoke collecting hood and the inner wall of the range hood housing behind the smoke collecting hood. In order to facilitate fixing the sound-absorbing cotton on the inner wall of the range hood, a mesh structure is usually provided on the side of the sound-absorbing cotton facing away from the inner wall of the range hood. The mesh structure is used to connect with the range hood through screws, so as to fix the sound-absorbing cotton on the inner wall of the range hood.

[0003] However, with the prolongation of the use time, a large amount of oil fume will gradually adhere to the sound-absorbing cotton, affecting the noise reduction effect. Since the oil fume is usually difficult to clean, after a large amount of oil fume adheres to the sound-absorbing cotton on the existing range hood, the whole sound-absorbing cotton is usually directly replaced, which not only easily causes material waste, but also increases the maintenance cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oil fume adsorption and noise reduction component and a range hood, so as to alleviate the technical problems existing in the prior art that since the oil fume is usually difficult to clean, after a large amount of oil fume adheres to the sound-absorbing cotton on the range hood, the whole sound-absorbing cotton is usually directly replaced, which not only easily causes material waste, but also increases the maintenance cost.

[0005] In a first aspect, the utility model provides an oil fume adsorption and noise reduction component, including a sound-absorbing plate and an oil absorption layer;

[0006] One side of the sound-absorbing plate is used to be attached to the inner wall of the range hood, the other side of the sound-absorbing plate is provided with the oil absorption layer, and the oil absorption layer is detachably connected to the sound-absorbing plate;

[0007] The sound-absorbing plate is used to absorb noise, and the oil absorption layer is used to adsorb impurities in the oil fume.

[0008] In an optional embodiment, the sound-absorbing plate and the oil absorption layer are fixedly connected by a snap connection method.

[0009] In an optional embodiment, a card slot is provided on the side of the sound-absorbing plate away from the inner wall of the range hood, and the oil absorption layer is snapped into the card slot.

[0010] In an optional embodiment, an extension part extending towards the inside of the slot is provided at the slot opening of the card slot, and the extension part abuts against the side of the oil absorption layer away from the bottom of the card slot.

[0011] In an alternative embodiment, there are a plurality of oil absorption layers, and the plurality of oil absorption layers are sequentially distributed on the side of the sound absorption panel away from the inner wall of the range hood along the direction of oil fume flow.

[0012] In an alternative embodiment, the plurality of oil absorption layers are sequentially and spaced apart.

[0013] In an alternative embodiment, from the smoke inlet to the smoke outlet of the range hood, the thickness of the sound absorption panel increases, and / or the thickness of the oil absorption layer decreases.

[0014] In an alternative embodiment, the sound absorption panel is a porous structure made of polyester fiber material, and the material of the oil absorption layer is polylactic acid.

[0015] In an alternative embodiment, buckles are provided on the periphery of the sound absorption panel, and the sound absorption panel is fixedly connected to the inner wall of the range hood through the buckles.

[0016] In a second aspect, the present utility model provides a range hood, including the oil fume adsorption and noise reduction assembly according to any one of the foregoing embodiments.

[0017] The oil fume adsorption and noise reduction component provided by the utility model comprises a sound absorption board and an oil absorption layer; one side of the sound absorption board is used for fitting with the inner wall of an oil fume extractor, an oil absorption layer is arranged on the other side of the sound absorption board, and the oil absorption layer is detachably connected with the sound absorption board; the sound absorption board is used for absorbing noise, and the oil absorption layer is used for adsorbing impurities in the oil fume. The oil fume adsorption and noise reduction component provided by the utility model is applied to an oil fume extractor. During use, the side of the sound absorption board facing away from the oil absorption layer can be fixed on the inner wall of the oil fume extractor. For example, the above-mentioned sound absorption board is fixed on the inner wall of the smoke collecting hood of the oil fume extractor or on the inner wall of the oil fume extractor housing behind the smoke collecting hood. When the oil fume extractor is started and the oil fume passes through the smoke collecting hood and the oil fume extractor housing behind the smoke collecting hood in sequence, the oil absorption layer will contact and adsorb oil droplets and other impurities in the oil fume prior to the sound absorption board, thereby playing a role in purifying the adsorbed oil fume. The noise generated during the flow of the oil fume will pass through the oil absorption layer and be absorbed by the sound absorption board, thereby playing a role in noise reduction. Among them, the sound absorption board can adopt a porous structure. Since the transmission of noise is a process of sound wave transmission, the noise can pass through the oil absorption layer. However, when the noise reaches the sound absorption board, the sound wave of the noise will be absorbed and weakened by the holes on the sound absorption board. Therefore, the oil absorption layer will not affect the noise reduction process of the sound absorption board. In addition, since the oil absorption layer intercepts oil droplets and other impurities in the oil fume, the holes on the sound absorption board are not easily blocked by oil fume impurities, and its noise reduction effect is not easily affected as the use time prolongs. It should be noted that when a large amount of oil fume impurities adhere to the oil absorption layer, resulting in a reduction in the oil fume adsorption effect, the oil fume adsorption and noise reduction component still needs to be cleaned or replaced. However, since the oil absorption layer is detachably connected with the sound absorption board, during the cleaning and replacement process, only the oil absorption layer can be detached from the sound absorption board, and then the oil absorption layer can be cleaned or replaced alone, without detaching the sound absorption board not adhered to by oil fume impurities for cleaning or replacement. Compared with the existing maintenance method of directly replacing the entire sound absorption cotton, not only can materials be effectively saved, but also the maintenance convenience of the oil fume adsorption and noise reduction component can be effectively improved, and the maintenance cost can be effectively reduced.

[0018] Compared with the prior art, the oil fume adsorption and noise reduction component provided by the utility model not only can adsorb oil fume by the oil absorption layer and absorb noise by the sound absorption board, but also can effectively prevent the oil fume from adhering to the sound absorption board in a large area, thereby effectively avoiding the influence of the oil fume on the noise reduction effect of the sound absorption board. And when it is necessary to clean or replace the oil fume adsorption and noise reduction component, only the oil absorption layer needs to be removed from the sound absorption board for cleaning or replacement, without replacing the entire sound absorption board together, which can effectively avoid material waste and reduce the maintenance cost.

[0019] The oil fume extractor provided by the utility model comprises the above-mentioned oil fume adsorption and noise reduction component, so the oil fume extractor has the same beneficial effects as the above-mentioned oil fume adsorption and noise reduction component.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Embodiment:

[0029] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, the oil fume adsorption and noise reduction component provided in this embodiment includes a sound absorption board 1 and an oil absorption layer 2; one side of the sound absorption board 1 is used to fit against the inner wall of the range hood, and the other side of the sound absorption board 1 is provided with the oil absorption layer 2, and the oil absorption layer 2 is detachably connected to the sound absorption board 1; the sound absorption board 1 is used to absorb noise, and the oil absorption layer 2 is used to adsorb impurities in the oil fume.

[0030] The oil fume adsorption and noise reduction component provided in this embodiment is applied to a range hood. During use, the side of the sound absorption board 1 facing away from the oil absorption layer 2 can be fixed to the inner wall of the range hood. For example, the above-mentioned sound absorption board 1 can be fixed on the inner wall of the smoke collecting hood of the range hood or on the inner wall of the range hood housing behind the smoke collecting hood.

[0031] When the range hood is started and the oil fume passes through the smoke collecting hood and the range hood housing behind the smoke collecting hood in sequence, the oil absorption layer 2 will come into contact with and adsorb impurities such as oil droplets in the oil fume prior to the sound absorption board 1, thereby playing a role in oil fume adsorption and purification. And the noise generated during the flow of the oil fume will pass through the oil absorption layer 2 and be absorbed by the sound absorption board 1, thereby playing a role in noise reduction.

[0032] Among them, the sound absorption board 1 can adopt a porous structure. Since the transmission of noise is a process of sound wave transmission, the noise can pass through the oil absorption layer 2. However, when the noise reaches the sound absorption board 1, the sound wave of the noise will be absorbed and weakened by the holes on the sound absorption board 1. Therefore, the oil absorption layer 2 will not affect the noise reduction process of the sound absorption board 1.

[0033] In addition, since the oil absorption layer 2 intercepts impurities such as oil droplets in the oil fume, the holes on the sound absorption board 1 are not easily blocked by oil fume impurities, and its noise reduction effect is not easily affected as the use time prolongs.

[0034] It should be noted that when a large amount of oil fume impurities adhere to the oil absorption layer 2, resulting in a reduction in the oil fume adsorption effect, the oil fume adsorption and noise reduction component still needs to be cleaned or replaced. However, since the oil absorption layer 2 is detachably connected to the sound absorption board 1, during the cleaning and replacement process, only the oil absorption layer 2 can be detached from the sound absorption board 1, and then the oil absorption layer 2 can be cleaned or replaced alone, without having to detach the sound absorption board 1 that is not adhered to by oil fume impurities for cleaning or replacement. Compared with the existing maintenance method of directly replacing the entire sound absorption cotton, it can not only effectively save materials, but also effectively improve the maintenance convenience of the oil fume adsorption and noise reduction component, and effectively reduce the maintenance cost.

[0035] Compared with the prior art, the oil fume adsorption and noise reduction component provided in this embodiment can not only utilize the oil absorption layer 2 to adsorb oil fume and the sound absorption board 1 to absorb noise, but also effectively prevent the oil fume from adhering to the sound absorption board 1 in a large area, thereby effectively avoiding the influence of the oil fume on the noise reduction effect of the sound absorption board 1. And when it is necessary to clean and replace this oil fume adsorption and noise reduction component, only the oil absorption layer 2 needs to be removed from the sound absorption board 1 for cleaning or replacement, without replacing the entire sound absorption board 1 together, which can effectively avoid material waste and reduce the maintenance cost.

[0036] In this embodiment, there are no restrictions on the materials of the sound absorption board 1 and the oil absorption layer 2, as long as the sound absorption board 1 can play a role in absorbing noise and the oil absorption layer 2 can enable oil fume impurities to adhere thereto to achieve the oil absorption effect. For example, the sound absorption board 1 can be made of materials such as glass fiber, sponge, and mineral wool, and the oil absorption layer 2 can be made of materials such as activated carbon and porous silica gel.

[0037] This embodiment preferably selects the sound absorption board 1 to be a porous structure made of polyester fiber material, and the material of the oil absorption layer 2 is polylactic acid.

[0038] When the material of the sound absorption board 1 is selected as polyester fiber, the sound absorption board 1 can have good sound absorption performance, and at the same time has good flame retardant and light weight properties. When the material of the oil absorption layer 2 is selected as polylactic acid, the oil absorption layer 2 has good oil absorption performance and good heat resistance.

[0039] There are various choices for the detachable connection method between the sound absorption board 1 and the oil absorption layer 2. For example, the sound absorption board 1 and the oil absorption layer 2 can be detachably connected by fasteners such as screws, or can be detachably connected by nylon hook-and-loop fasteners.

[0040] To improve the connection stability and the convenience of installation and disassembly between the sound absorption board 1 and the oil absorption layer 2, this embodiment preferably fixedly connects the sound absorption board 1 and the oil absorption layer 2 by a snap connection method.

[0041] Further, as Figure 2 and Figure 3 shown, a card slot 10 is provided on the side of the sound absorption board 1 away from the inner wall of the range hood, and the oil absorption layer 2 is snap-fitted into the card slot 10.

[0042] When it is necessary to install the oil absorption layer 2 on the sound absorption board 1, the oil absorption layer 2 can be directly inserted into the card slot 10. At this time, the interference fit between the oil absorption layer 2 and the card slot 10 can ensure the installation stability of the oil absorption layer 2 in the card slot 10. When it is necessary to disassemble the oil absorption layer 2 from the sound absorption board 1, the oil absorption layer 2 can be directly pulled out from the card slot 10.

[0043] Further, an extension portion 100 extending towards the inside of the slot is provided at the slot opening of the card slot 10, and the extension portion 100 abuts against the side of the oil absorption layer 2 away from the bottom of the card slot 10.

[0044] Since the oil absorbing layer 2 is made of polylactic acid material, the oil absorbing layer 2 has a certain elasticity. When the oil absorbing layer 2 needs to be installed in the card slot 10, the oil absorbing layer 2 can be directly pressed into the card slot 10. The oil absorbing layer 2 will be squeezed and deformed by the extension part 100 during the process of entering the card slot 10. However, after the oil absorbing layer 2 completely enters the card slot 10, it will restore the deformation and abut against the extension part 100 in the card slot 10, so as to be stably fixed in the card slot 10.

[0045] It can be seen that the extension portion 100 can limit the oil absorption layer 2 , further improving the installation stability of the oil absorption layer 2 in the card slot 10 .

[0046] In order to improve the surface smoothness of the oil fume adsorption and noise reduction component and maximize the limiting effect of the extension part 100, in this embodiment, the extension part 100 is preferably arranged parallel to the bottom of the slot 10.

[0047] In addition, in order to improve the stability of the oil-absorbing layer 2 in the card slot 10, in this embodiment, the position of the oil-absorbing layer 2 corresponding to the extension portion 100 is preferably provided with a recessed portion for accommodating the extension portion 100. At this time, the cross-section of the oil-absorbing layer 2 is approximately a convex shape. When the oil-absorbing layer 2 is inserted into the card slot 10, the side of the oil-absorbing layer 2 facing away from the bottom of the card slot 10 can be flush with the side of the extension portion 100 facing away from the bottom of the card slot 10.

[0048] like Figure 1 and Figure 2 As shown, there are multiple oil absorbing layers 2, and the multiple oil absorbing layers 2 are sequentially distributed on the side of the sound absorbing board 1 away from the inner wall of the range hood along the flow direction of the oil smoke.

[0049] The multiple oil absorption layers 2 allow the user to replace part of the oil absorption layers 2 in a targeted manner according to the oil fume adhesion conditions without having to replace all of the oil absorption layers 2 together, thereby effectively improving the maintenance convenience of the oil fume adsorption and noise reduction component.

[0050] Furthermore, a plurality of oil absorbing layers 2 are distributed in sequence at intervals.

[0051] The interval between two adjacent oil absorbing layers 2 enables the sound absorbing board 1 at the interval to provide support for the oil absorbing layer 2 , thereby improving the use stability of the oil absorbing layer 2 .

[0052] In addition, the interval between two adjacent oil absorption layers 2 can also provide operating space for installing and removing the oil absorption layer 2, thereby improving the convenience of installing and removing the oil absorption layer 2.

[0053] It should be noted that when multiple oil absorption layers 2 are distributed at intervals in sequence, the sound absorption panel 1 at the interval between two adjacent oil absorption layers 2 can also play a role in adsorbing oil fume. Although the noise reduction effect of the sound absorption panel 1 at the oil fume adsorption position will weaken with the extension of the use time, since the area of the sound absorption panel 1 blocked by the oil absorption layer 2 can still play a noise reduction role, the entire sound absorption panel 1 still does not need to be replaced at this time.

[0054] In this embodiment, the width direction of the oil absorption layer 2 is the same as the oil fume flow direction. Based on this, along the oil fume flow direction, the widths of multiple oil absorption layers 2 can be decreasing.

[0055] The decreasing widths of multiple oil absorption layers 2 can enable the oil absorption layer 2 that first contacts the oil fume to have a larger adsorption area. Since the oil fume will sequentially contact multiple oil absorption layers 2 during the flow process, and at the same time, impurities such as oil droplets in the oil fume will gradually decrease, the oil absorption layer 2 that later contacts the oil fume does not need to be set with a wider width.

[0056] It can be seen that the widths of multiple oil absorption layers 2 decreasing along the oil fume flow direction can effectively save the material cost of the oil absorption layer 2 on the premise of ensuring the oil fume absorption effect.

[0057] In addition, based on the fact that impurities such as oil droplets will gradually decrease during the flow of the oil fume, in the multiple oil absorption layers 2 provided in this embodiment, the interval between each group of two adjacent oil absorption layers 2 can increase along the oil fume flow direction.

[0058] The interval between each group of two adjacent oil absorption layers 2 increasing along the oil fume flow direction can not only further save the material cost of the oil absorption layer 2, but also effectively improve the noise reduction effect of the sound absorption panel 1.

[0059] In this embodiment, from the smoke inlet to the smoke outlet of the range hood, the thickness of the sound absorption panel 1 increases or the thickness of the oil absorption layer 2 decreases, or the thickness of the sound absorption panel 1 increases and the thickness of the oil absorption layer 2 decreases.

[0060] During the flow process of the oil fume, the impurities in the oil fume will become less and less due to the oil fume absorption effect of the oil absorption layer 2. Therefore, from the smoke inlet to the smoke outlet of the range hood, the thickness of the oil absorption layer 2 decreases, which can also achieve the effect of saving the material cost of the oil absorption layer 2. Correspondingly, at this time, the thickness of the sound absorption panel 1 increases, and the noise reduction effect of the sound absorption panel 1 can be gradually improved on the premise that the oil fume impurities decrease.

[0061] In this embodiment, buckles are provided on the peripheral side of the sound absorption panel 1, and the sound absorption panel 1 is fixedly connected to the inner wall of the range hood through the buckles.

[0062] The buckles can realize the clamping and fixing between the sound absorption panel 1 and the range hood, thereby effectively improving the convenience of installation and disassembly of the sound absorption panel 1.

[0063] Among them, the buckle can adopt a claw with good elasticity. Correspondingly, a clamping hole matching the claw is provided on the side wall of the range hood.

[0064] To improve the appearance beauty of the oil fume adsorption and noise reduction component, the claw can be fixed on the side of the sound absorption board 1 facing away from the oil absorption layer 2.

[0065] This embodiment also provides a range hood, which includes the above-mentioned oil fume adsorption and noise reduction component. Therefore, the range hood and the above-mentioned oil fume adsorption and noise reduction component can solve the same technical problems and achieve the same technical effects, which will not be elaborated here.

[0066] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
