Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking equipment technology, and in particular to an oil fume treatment device and an integrated stove. Background Technology
[0002] An integrated cooktop is a kitchen appliance that integrates multiple functions into one unit, such as a combination of "fume hood + cooktop + storage", "fume hood + cooktop + disinfection", or "fume hood + cooktop + steaming / baking".
[0003] In related technologies, integrated cooktops include a fume extraction device used to remove cooking fumes. The fume extraction chamber of the fume extraction device is connected to the interface of a fan inside the fume collection chamber. The fume extraction device uses single-sided air outlet; one end of the fume extraction chamber is fitted with an air outlet seat, and the other end is sealed with an end cap.
[0004] However, during the exhaust process, the fume treatment device may produce significant noise in the exhaust chamber. Utility Model Content
[0005] This utility model provides an oil fume treatment device and an integrated stove to solve the problem of excessive noise in the exhaust chamber during the smoke exhaust process of the oil fume treatment device.
[0006] In a first aspect, embodiments of the present invention provide an oil fume treatment device, comprising:
[0007] A smoke collecting component, wherein the smoke collecting component has a smoke collecting cavity;
[0008] A fan is installed inside the smoke collection chamber and has an air outlet.
[0009] A smoke exhaust component, which is connected to the air outlet, has a smoke exhaust chamber and two smoke exhaust ports communicating with the smoke exhaust chamber;
[0010] An end cap assembly, comprising an end cap and a noise reduction module, wherein the end cap is connected to one of the two exhaust ports, and the noise reduction module is connected to the end cap.
[0011] In one possible implementation, the noise reduction module includes a fixing member and a sound-absorbing member, the fixing member being connected to the end cap, and the sound-absorbing member being disposed within the space enclosed by the fixing member and the end cap.
[0012] This design secures the sound-absorbing component within the space enclosed by the fixing component and the end cap, thus improving the stability of the sound-absorbing component.
[0013] In one possible implementation, the fastener includes a first plate and a second plate, the second plate being connected between the first plate and the end cap, and the sound-absorbing element being located between the first plate and the end cap in the thickness direction of the end cap.
[0014] In one possible implementation, the first plate is provided with a plurality of through holes, which are spaced apart.
[0015] With this design, some of the noise generated by the fumes is dissipated by friction with the through-holes as it passes through them, thus increasing the noise reduction effect.
[0016] In one possible implementation, the first plate is provided with a plurality of bending segments, and each bending segment is provided with a plurality of through holes.
[0017] With this setup, the area of the first board will increase, and the number of through holes will also increase, thereby further enhancing the noise reduction effect of the noise reduction module.
[0018] In one possible implementation, multiple bent segments are connected sequentially along the length of the end cap.
[0019] With this setup, the noise waves generated by the cooking fumes will be reflected when they come into contact with the bend. Some of the noise waves within the bend will cancel each other out after reflection, thus further improving the noise reduction effect.
[0020] In one possible implementation, the noise reduction module further includes a pressure plate and an elastic element, the pressure plate and the elastic element being disposed between the sound-absorbing element and the end cap, the elastic element connecting the pressure plate and the end cap, and the pressure plate abutting against the sound-absorbing element.
[0021] With this configuration, the sound-absorbing component adheres to the first plate after being pressed by the pressure plate, avoiding gaps between the sound-absorbing component and the first plate. This allows noise waves to directly enter the sound-absorbing component after passing through the first plate, thus improving the noise reduction effect.
[0022] In one possible implementation, the noise reduction module is disposed within the smoke exhaust chamber.
[0023] With this configuration, the noise reduction module can compress the space of the exhaust chamber. The smaller space of the exhaust chamber reduces the residence time of oil fumes in the exhaust chamber, thereby improving emission efficiency.
[0024] In one possible implementation, the diameter of the through hole is greater than or equal to 2 mm and less than or equal to 3 mm;
[0025] The distance between two adjacent through holes is greater than or equal to 6 mm and less than or equal to 10 mm.
[0026] With this configuration, if the diameter of the through-hole is less than 2mm, it will be too small, making it prone to blockage by particles or other impurities, thus reducing the noise reduction effect of the first board. If the diameter of the through-hole is greater than 3mm, it will be too large, causing most noise waves to pass directly through the center of the through-hole, reducing the interaction between the sound waves and the hole wall, and thus reducing the noise reduction effect of the first board. By limiting the diameter of the through-hole, the noise reduction effect of the first board can be improved.
[0027] If the distance between two adjacent through holes is less than 6mm, the spacing will be too small, causing turbulence in the airflow and resulting in additional aerodynamic noise. If the distance between two adjacent through holes is greater than 10mm, the distance will be too large, reducing the number of through holes on the first plate. This reduces the amount of sound waves entering the sound-absorbing component, thus decreasing the noise reduction effect of the noise reduction module. By limiting the distance between two adjacent through holes, additional aerodynamic noise can be reduced, and the noise reduction effect of the noise reduction module can be improved.
[0028] Secondly, the utility model embodiment provides an integrated stove, including the oil fume treatment device described in any one of the first aspects.
[0029] This utility model provides an oil fume treatment device and an integrated stove. The device is connected to one of the exhaust ports via an end cap, and the end cap is also connected to a noise reduction module. During the exhaust process, the noise generated by the oil fumes in the exhaust chamber is absorbed by the noise reduction module, thereby reducing the noise. Attached Figure Description

[0051] In related technologies, oil fume treatment devices often experience significant noise levels in the exhaust chamber during the fume extraction process. Research has revealed that this problem arises because, after the oil fumes enter the exhaust chamber from the collection chamber via the fan, some of the fumes flow towards the end with the end cap and then towards the air outlet. During this process, the oil fumes cause air turbulence within the exhaust chamber 301, leading to noise generation and resulting in significant noise levels in the exhaust chamber.
[0052] To address the aforementioned issues, this utility model provides an oil fume treatment device and integrated stove, which includes a noise reduction module connected to an exhaust port via an end cap. The end cap is also connected to the noise reduction module. During the exhaust process, the noise generated by the oil fumes in the exhaust chamber is absorbed by the noise reduction module, thereby reducing noise levels.
[0053] The fume treatment device and integrated stove provided in this utility model embodiment will be described in detail below with reference to specific embodiments.
[0054] This utility model provides an oil fume treatment device for use in integrated stoves.
[0055] like Figures 1 to 4 As shown, the fume treatment device includes a fume collection component 10, a fan 20, a fume exhaust component 30, and an end cap assembly 40. The fume collection component 10 has a fume collection chamber 101. The fan 20 is installed inside the fume collection chamber 101 and has an air outlet 201. The fume exhaust component 30 is connected to the air outlet 201 and has an exhaust chamber 301 and two exhaust ports 302 communicating with the exhaust chamber 301. The end cap assembly 40 includes an end cap 41 and a noise reduction module 42. The end cap 41 is connected to one of the two exhaust ports 302, and the noise reduction module 42 is connected to the end cap 41. With this configuration, during the fume exhaust process, the noise generated by the fumes in the exhaust chamber 301 is absorbed by the noise reduction module, thereby reducing noise.
[0056] In some examples, the X-axis is the length direction of the smoke collecting component 10, the Y-axis is the width direction of the smoke collecting component 10, and the Z-axis is the height direction of the smoke collecting component 10. The X, Y, and Z axes are perpendicular to each other. Two smoke exhaust ports 302 are arranged opposite each other on both sides of the smoke exhaust component 30 along the X-axis. The smoke exhaust chamber 301 is a strip-shaped cavity extending along the X-axis.
[0057] In some examples, the smoke collector 10 generates negative pressure when the fan 20 is working, which sucks away the oil fumes generated during cooking and allows the oil fumes to enter the exhaust chamber 301 through the air outlet 201 and finally flow through the exhaust port 302 for discharge.
[0058] The shape of the smoke exhaust port 302 can be square, or it can be round or oval.
[0059] In some examples, in order to ensure that the end cap 41 can completely seal one of the exhaust ports 302, the shape of the end cap 41 corresponds to the shape of the exhaust port 302, and the size of the end cap 41 needs to be slightly larger than the size of the exhaust port 302.
[0060] It should be noted that the shape of the end cap 41 does not necessarily correspond to the exhaust port 302. As long as the end cap 41 completely covers the exhaust port 302, for example, the exhaust port 302 is square and the end cap 41 is round.
[0061] The fume treatment device also includes multiple screws. The end cap 41 is fixedly connected to the exhaust component 30 by screws. This connection method can be achieved by rotating the screw threads, without the need for complicated equipment, which is suitable for on-site construction. In addition, the screw connection method has a detachable design, which is convenient for maintenance or replacement and has a high reusability.
[0062] It should be noted that the screw connection method also has anti-loosening technology. By adding washers between the screw and the end cover 41 or by pre-tightening the screw, the vibration of the exhaust component 30 caused by the flow of oil fumes through the exhaust chamber 301 can be reduced, thus preventing the end cover 41 from becoming loose.
[0063] In other embodiments, the end cap 41 and the smoke exhaust component 30 can also be connected by adhesive or welding.
[0064] In one possible implementation, see Figure 4 As shown, the noise reduction module 42 includes a fixing member 421 and a sound-absorbing member 422. The fixing member 421 is connected to the end cap 41, and the sound-absorbing member 422 is disposed within the space enclosed by the fixing member 421 and the end cap 41. By placing the sound-absorbing member 422 within the space enclosed by the fixing member 421 and the end cap 41, the movement of the sound-absorbing member 422 is restricted, thereby achieving the function of fixing the sound-absorbing member 422.
[0065] In some examples, the sound-absorbing component 422 can be sound-absorbing cotton. The noise reduction principle of the sound-absorbing cotton is to convert sound energy into heat energy through the pore structure of the porous material. Specifically, when sound waves enter the interconnected micropores inside the sound-absorbing cotton, air molecules vibrate violently in the pores and rub against the pore walls (fibers or foam pores) repeatedly. The mechanical energy of the sound waves is converted into heat energy due to friction, thereby achieving the noise reduction effect.
[0066] In some examples, the fastener 421 is fixedly connected to the end cap 41 by screws. When the end cap 41 is removed from the smoke exhaust component 30, the noise reduction module 42 can be removed along with the end cap 41, making the overall disassembly convenient.
[0067] like Figure 4 As shown, in one possible embodiment, the fastener 421 includes a first plate 4211 and a second plate 4212, the second plate 4212 being connected between the first plate 4211 and the end cap 41, and the sound-absorbing member 422 being located between the first plate 4211 and the end cap 41 in the thickness direction of the end cap 41.
[0068] The thickness direction of the end cap 41 is the X-axis direction. The length direction of the end cap 41 can be the Z-axis direction. The width direction of the end cap 41 can be the Y-axis direction.
[0069] The second plate 4212 can be fixedly connected to the first plate 4211 by bolts. The second plate 4212 can be fixedly connected to the end cap 41 by bolts.
[0070] In some examples, the fastener 421 includes a first plate 4211 and two second plates 4212, which are disposed opposite each other in the length direction of the end cap 41. Each second plate 4212 is connected between the first plate 4211 and the end cap 41, and the sound-absorbing member 422 is disposed within the space enclosed by the first plate 4211, the second plates 4212 and the end cap 41.
[0071] In one possible implementation, see Figure 4 As shown, the first plate 4211 has multiple through holes 4213 spaced apart. During transmission, the noise waves generated by the cooking fumes first pass through the through holes 4213 and are then absorbed by the sound-absorbing component 422. Specifically, some of the noise waves are absorbed by the through holes 4213, thus increasing the noise reduction effect. Furthermore, after passing through the through holes 4213 of the first plate 4211, the noise waves enter the sound-absorbing component 422 to further reduce noise.
[0072] It should be noted that when noise waves enter through hole 4213, the noise waves rub against the hole wall, which can convert sound energy into heat energy and thus increase the noise reduction effect.
[0073] In one possible implementation, the first plate 4211 is provided with multiple bending segments, and each bending segment is provided with multiple through holes 4213. By providing multiple bending segments on the first plate 4211, the surface area of the first plate 4211 is indirectly increased. By increasing the area of the first plate 4211, the number of through holes 4213 can be increased. The increase in the number of through holes 4213 can further enhance the noise reduction effect of the noise reduction module 42.
[0074] In some examples, the through hole 4213 can be circular. In other embodiments, the through hole 4213 can also be square or other shapes.
[0075] In one possible implementation, multiple bent sections are connected sequentially along the length of the end cap 41. With this arrangement, when the noise waves generated by the cooking fumes come into contact with the bent sections, the direction of sound wave propagation changes, and some sound waves undergo multiple reflections on the surface of the bent sections. When the incident wave and the reflected wave are out of phase, the sound energy cancels each other out, thereby improving the noise reduction effect.
[0076] In some examples, the cross-section of the bent segment can be triangular.
[0077] In some examples, multiple bends connected together can form a wavy shape.
[0078] In one possible implementation, see Figure 4As shown, the noise reduction module 42 also includes a pressure plate 43 and an elastic element 44. The pressure plate 43 and the elastic element 44 are disposed between the sound-absorbing element 422 and the end cap 41. The elastic element 44 connects the pressure plate 43 and the end cap 41. The pressure plate 43 abuts against the sound-absorbing element 422.
[0079] When the elastic element 44 is positioned between the sound-absorbing element 422 and the end cap 41, the elastic element 44 is in a compressed state. The elastic element 44 applies pressure to the pressure plate 43, and the pressure plate 43 squeezes the sound-absorbing element 422, causing the sound-absorbing element 422 to fit against the first plate 4211. This prevents gaps between the sound-absorbing element 422 and the first plate 4211, allowing noise waves to directly enter the sound-absorbing element 422 after passing through the first plate 4211, thereby improving the noise reduction effect.
[0080] The elastic element 44 is a component that can undergo elastic deformation. For example, the elastic element 44 can be a spring.
[0081] In one possible implementation, the noise reduction module 42 is disposed within the exhaust chamber 301. The noise reduction module 42 can compress the space of the exhaust chamber 301. The reduced space of the exhaust chamber 301 can decrease the residence time of oil fumes within the exhaust chamber, thereby improving emission efficiency.
[0082] See in some examples Figure 5 As shown, the diameter of the through hole 4213 is φ, which is greater than or equal to 2 mm and less than or equal to 3 mm. For example, the value of φ can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.8 mm, or 3 mm, etc.
[0083] If φ is less than 2mm, the diameter of the through-hole 4213 will be too small, making it easily clogged by particles or other impurities, thus reducing the noise reduction effect of the first plate 4211. If φ is greater than 3mm, the diameter of the through-hole 4213 will be too large, causing most noise waves to pass directly through the center of the through-hole 4213, reducing the interaction between the sound waves and the hole wall, and thus reducing the noise reduction effect of the first plate 4211. By limiting the diameter of the through-hole 4213, the noise reduction effect of the first plate 4211 can be improved.
[0084] See in some examples Figure 5 As shown, the distance between two adjacent through holes 4213 is d, which is greater than or equal to 6 mm and less than or equal to 10 mm. For example, the value of d can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, or 10 mm, etc.
[0085] The spacing between two adjacent through holes 4213 refers to the spacing between the centers of two adjacent through holes 4213.
[0086] If d is less than 6mm, the distance between two adjacent through holes 4213 will be too small, causing turbulence in the airflow as it passes through the through holes 4213, resulting in additional aerodynamic noise. If d is greater than 10mm, the distance between two adjacent through holes 4213 will be too large, reducing the number of through holes 4213 on the first plate 4211, thus reducing the sound waves entering the sound-absorbing component 422 and decreasing the noise reduction effect of the noise reduction module 42. By limiting the distance between two adjacent through holes 4213, additional aerodynamic noise can be reduced, and the noise reduction effect of the noise reduction module 42 can be improved.
