Description

Range hood components and integrated cooktop

[0001] This application claims priority to Chinese patent application filed on August 30, 2024, with application number "202422138758.3" entitled "Range Hood Components and Integrated Cooktop", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cooking equipment technology, and more specifically, to a range hood assembly and an integrated stove. Background Technology

[0003] A range hood and cooktop combo is a kitchen appliance that integrates a cooktop and a range hood into one unit. A range hood and cooktop combo generally includes a volute, an impeller, and a motor. The motor drives the rotating impeller to extract cooking fumes.

[0004] In related technologies, motors are often fixed inside the volute using screws or other connecting structures. The motor needs to rotate at high speed during operation to generate sufficient negative pressure suction.

[0005] However, high-speed rotating motors generate vibrations and shocks, which are transmitted throughout the entire machine, increasing operating noise. These vibrations and shocks also affect the stability of the connection structure, causing the motor to loosen or become misaligned. This results in the technical problems of high operating noise and poor motor positioning stability in integrated range hoods and cooktops. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the prior art.

[0007] Therefore, the first aspect of this application proposes a smoke hood assembly.

[0008] The second aspect of this application proposes an integrated stove.

[0009] In view of the above, a first aspect of this application provides a range hood assembly, the range hood assembly comprising: a volute housing, the volute housing including a cavity; a motor, the motor being disposed within the volute housing and connected to the volute housing; and a shock-absorbing component, the shock-absorbing component being disposed within the volute housing, the shock-absorbing component being located between the volute housing and the motor in the axial direction of the motor, and in a second direction, the shock-absorbing component being located between the volute housing and the motor, the second direction being perpendicular to the axial direction of the motor.

[0010] This application proposes a range hood assembly, which is a power structure on an integrated stove. Specifically, the range hood assembly can extract oil fumes and discharge the extracted oil fumes to a designated area through a flue.

[0011] The range hood assembly includes a volute, a motor, and an impeller. The volute forms the main frame structure of the range hood assembly, used to position and support other working structures on the assembly. An internal cavity is formed within the volute, and an inlet and outlet are provided on the volute, connecting the cavity to the external space. The motor is installed within the cavity, and its power output is connected to the impeller. The motor drives the impeller to rotate, drawing oil fumes into the volute through the inlet and, after pressurization and acceleration, expelling the fumes from the outlet, thus achieving the extraction and centralized discharge of oil fumes. Specifically, the motor is connected to the volute, and after assembly, the motor is fixed inside the volute.

[0012] Based on this, a vibration damping component is installed between the motor and the volute. This component is made of shock-absorbing materials such as rubber. After the connection between the motor and the volute is completed, the vibration damping component can be clamped and positioned between them. Specifically, in the axial direction of the motor, part of the vibration damping component is located between the motor and the volute. This part of the vibration damping component can absorb vibration impacts in the axial direction of the motor, preventing axial vibration impacts from being transmitted to the volute. Correspondingly, in a second direction perpendicular to the axial direction, part of the vibration damping component is located between the volute and the motor. This part of the vibration damping component can absorb vibration impacts in the second direction, preventing lateral vibration impacts from being transmitted to the volute.

[0013] Specifically, during the high-speed rotation of the motor, the shock-absorbing components can absorb the impact force generated by the motor through deformation between the motor and the volute, thereby preventing the vibration and shock on the motor from being transmitted to the volute. This reduces the vibration and shock amplitude of the volute and the entire range hood assembly, thereby reducing the operating noise of the range hood assembly and solving the technical problem of high operating noise in related technologies.

[0014] Furthermore, the shock-absorbing components between the motor and the volute can reduce the impact on the connecting parts between the motor and the volute, reduce the probability of the connecting parts loosening or even falling off under vibration and shaking, improve the positioning stability of the motor, and thus solve the technical problem of poor motor positioning stability in related technologies.

[0015] Meanwhile, the vibrations and shocks transmitted to the volute can create gaps between the volute, motor, and connecting components. Wastewater and grease inside the volute may leak through these gaps to the outside of the range hood assembly, causing contamination. To address this, shock-absorbing components can absorb the impact and suppress the formation of these gaps, thereby reducing the probability of liquid and grease leakage.

[0016] It is evident that by incorporating vibration damping components, the technical effects of reducing the operating noise of the range hood components, improving the stability and reliability of the motor, and enhancing the sealing performance of the range hood components are achieved.

[0017] Specifically, the shock absorber is made of nitrile rubber, which has excellent oil resistance, thus extending the service life of the shock absorber.

[0018] The hardness range of the vibration damping component is greater than or equal to HS30 and less than or equal to HS70. By limiting the hardness range to HS30 or greater, the vibration damping component can be ensured to have sufficient strength and elasticity, thereby achieving the effects of vibration damping and preventing screw loosening. By limiting the hardness to HS70 or less, the vibration damping component can be made sufficiently flexible, allowing it to be easily pressed into the predetermined installation position, thus reducing the assembly difficulty of the vibration damping component.

[0019] In some technical solutions of this application, optionally, the volute includes a mounting hole, and the shock-absorbing component is embedded in the mounting hole; the shock-absorbing component includes a through hole, and the motor is connected to the volute through the through hole.

[0020] Optionally, in some technical solutions of this application, the shock-absorbing component includes: a pad block, which is inserted through the mounting hole, and the through hole is located in the pad block; wherein, the periphery of the pad block includes a first rib and a second rib, the first rib being located inside the volute and the second rib being located outside the volute, and the first rib and the second rib clamping the volute.

[0021] In some technical solutions of this application, optionally, the end of the through hole facing the outside of the volute is the outlet, and the end of the through hole facing the inside of the volute is the inlet; the diameter of the inlet is larger than the diameter of the outlet.

[0022] In some technical solutions of this application, optionally, the outer diameter of the shock-absorbing component is D0; the outlet aperture is D1, and D0 and D1 satisfy the relationship: 0.405≤D1÷D0≤0.477; the inlet aperture is D2, and D0 and D2 satisfy the relationship: 0.481≤D2÷D0≤0.543.

[0025] In some technical solutions of this application, optionally, the number of damping components is N, and the N damping components are evenly distributed around the mounting hole, where N is an integer greater than or equal to 3.

[0026] In some technical solutions of this application, optionally, the smoke hood assembly further includes: an impeller, which is disposed inside the volute and connected to the motor.

Detailed Implementation

[0046] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0048] The following describes, with reference to Figures 1 to 15, some embodiments of the range hood assembly and integrated cooktop according to this application.

[0049] As shown in Figures 3, 4, and 5, one embodiment of this application proposes a range hood assembly 100, which includes: a volute 110, the volute 110 including a cavity 1102; a motor 120 disposed within the volute 110 and connected to the volute 110; and a shock-absorbing component 130 disposed within the volute 110. In the axial direction of the motor 120 (indicated by arrow b in Figure 5), the shock-absorbing component 130 is located between the volute 110 and the motor 120, and in a second direction (indicated by arrow c in Figure 5), the shock-absorbing component 130 is located between the volute 110 and the motor 120, the second direction being perpendicular to the axial direction of the motor 120.

[0050] This application proposes a range hood assembly 100, which is a power structure on an integrated stove 200. Specifically, the range hood assembly 100 can extract oil fumes and discharge the extracted oil fumes to a designated area through a flue 2102.

[0051] The range hood assembly 100 includes a volute 110, a motor 120, and an impeller 140. The volute 110 forms the main frame structure of the range hood assembly 100, used to position and support other working structures on the assembly. A cavity 1102 is formed inside the volute 110, and an inlet and an outlet 1304 are provided on the volute 110, connecting the cavity 1102 and the external space of the volute 110. The motor 120 is installed inside the cavity 1102, and its power output end is connected to the impeller 140. The motor 120 drives the impeller 140 to rotate, thereby drawing oil fumes into the volute 110 through the inlet and, after pressurization and acceleration, discharging the oil fumes from the outlet 1304, thus achieving the extraction and centralized discharge of oil fumes. Specifically, the motor 120 is connected to the volute 110, and after assembly, the motor 120 is fixed inside the volute 110.

[0052] Based on this, a shock-absorbing component 130 is provided between the motor 120 and the volute 110. The shock-absorbing component 130 is made of a material that can absorb impact, such as rubber. After the connection between the motor 120 and the volute 110 is completed, the shock-absorbing component 130 can be clamped and positioned between the two. Specifically, in the axial direction of the motor 120, a portion of the shock-absorbing component 130 is located between the motor 120 and the volute 110. This portion of the shock-absorbing component 130 can absorb vibration impact in the axial direction of the motor 120, preventing the vibration impact in the axial direction from being transmitted to the volute 110. Correspondingly, in a second direction perpendicular to the axial direction, a portion of the shock-absorbing component 130 is located between the volute 110 and the motor 120. This portion of the shock-absorbing component 130 can absorb vibration impact in the second direction, preventing the lateral vibration impact from being transmitted to the volute 110.

[0053] Specifically, during the high-speed rotation of the motor 120, the shock-absorbing component 130 can absorb the impact force generated by the motor 120 through deformation between the motor 120 and the volute 110, thereby preventing the vibration and shock on the motor 120 from being transmitted to the volute 110, thus reducing the vibration amplitude of the volute 110 and the entire range hood assembly 100, thereby reducing the operating noise of the range hood assembly 100 and solving the technical problem of high operating noise in related technologies.

[0054] Furthermore, the shock-absorbing component 130 between the motor 120 and the volute 110 can also reduce the impact on the connecting component between the motor 120 and the volute 110, reduce the probability of the connecting component loosening or even falling off under vibration, improve the positioning stability of the motor 120, and thus solve the technical problem of poor positioning stability of the motor 120 in the related art.

[0055] Meanwhile, the vibrations and shocks transmitted to the volute 110 can create gaps between the volute 110, the motor 120, and the connecting components. Wastewater and grease inside the volute 110 may leak through these gaps to the outside of the range hood assembly 100, causing pollution. To address this, the shock-absorbing component 130 can absorb the impact and suppress the formation of these gaps, thereby reducing the probability of liquid and grease leakage.

[0056] It can be seen that by setting the shock-absorbing component 130, the technical effects of reducing the operating noise of the range hood assembly 100, improving the working stability and reliability of the motor 120, and enhancing the sealing performance of the range hood assembly 100 are achieved.

[0057] Specifically, the shock absorber 130 is made of nitrile rubber, which has excellent oil resistance, thereby extending the service life of the shock absorber 130.

[0058] The hardness range of the shock-absorbing component 130 is greater than or equal to HS30 and less than or equal to HS70. By limiting the hardness range to HS30 or greater, the shock-absorbing component 130 can be ensured to have sufficient strength and elasticity, thereby achieving the effects of shock absorption and preventing screw loosening. By limiting the hardness of the shock-absorbing component 130 to HS70 or less, the shock-absorbing component 130 can be made sufficiently flexible, allowing it to be smoothly pressed into the predetermined installation position, thereby reducing the assembly difficulty of the shock-absorbing component 130.

[0059] As shown in Figures 6, 7 and 8, in some embodiments of this application, optionally, the volute 110 includes a mounting hole 1104, and the shock-absorbing component 130 is embedded in the mounting hole 1104; the shock-absorbing component 130 includes a through hole 1302, and the motor 120 is connected to the volute 110 through the through hole 1302.

[0060] In this embodiment, a mounting hole 1104 is provided at the bottom of the volute 110, which connects the inside and outside of the volute 110. The shock-absorbing component 130 is embedded in the mounting hole 1104. A through hole 1302 is provided on the shock-absorbing component 130, which is located inside the mounting hole 1104. The motor 120 is connected to the volute 110 through the through hole 1302. Specifically, the motor 120 can be partially inserted into the through hole 1302, or the motor 120 can be connected through a connecting component inserted into the through hole 1302.

[0061] Correspondingly, the motor 120 includes a fixing part with a screw hole. During assembly, the through hole 1302 needs to be aligned with the screw hole. Specifically, the fixing part can be a fixing foot on the motor 120 bracket.

[0062] Based on this, the motor 120 and the volute 110 are connected by a connecting component. After the through hole 1302 and the screw hole are aligned, the connecting component is screwed into the screw hole to shorten the distance between the head of the connecting component and the fixed part. Thus, the volute 110 and the shock absorber 130 are clamped and positioned by the fixed part and the head of the connecting component, ensuring that the shock absorber 130 can absorb the impact force between the volute 110 and the fixed part.

[0063] Therefore, the connection structure provided in this embodiment can complete the positioning and installation of the shock absorber 130 while connecting the motor 120 and the volute 110, so that the shock absorber 130 can be accurately assembled to the predetermined position without relying on other positioning structures, thereby achieving the technical effect of reducing the structural complexity and assembly complexity of the smoke hood assembly 100 and improving the reliability of the shock absorber 130.

[0064] Specifically, the connecting components include: combinations of bolts, studs and nuts, screws, etc.

[0065] As shown in Figures 5, 9, and 10, in some embodiments of this application, optionally, the shock-absorbing component 130 includes: a pad 132, which passes through the mounting hole 1104, and a through hole 1302 located in the pad 132; wherein, the periphery of the pad 132 includes a first rib 1322 and a second rib 1324, the first rib 1322 being located inside the volute 110, and the second rib 1324 being located outside the volute 110, and the first rib 1322 and the second rib 1324 clamping the volute 110.

[0066] In this embodiment, the fixing part extends outward relative to the motor 120, and the shock-absorbing component 130 includes a pad 132. The peripheral side of the pad 132 is provided with a first protruding rib 1322 and a second protruding rib 1324. The first protruding rib 1322 and the second protruding rib 1324 are annular and are spaced apart in the axial direction to form a slot between them.

[0067] During assembly, the pad 132 is first pressed into the mounting hole 1104 at the bottom of the housing. The first rib 1322 is located inside the housing, and the second rib 1324 is located outside the housing. The first rib 1322 and the second rib 1324 together clamp the housing, thereby achieving the pre-positioning of the pad 132 and preventing the pad 132 from falling out of the mounting hole 1104.

[0068] After the pre-positioning of the pad 132 is completed, the fixing part is inserted into the through hole 1302 on the pad 132 to complete the pre-positioning of the motor 120. In this case, the pad 132 is clamped by the inner surface of the mounting hole 1104 and the outer surface of the fixing part, and the axial and radial positioning of the pad 132 is achieved in conjunction with the aforementioned first protrusion 1322 and second protrusion 1324.

[0069] In the axial direction of the motor 120, the first rib 1322 can absorb axial vibration impact between the inner surfaces of the motor 120 and the volute 110. Correspondingly, in the second direction, the pad 132 embedded in the mounting hole 1104 can absorb lateral vibration impact between the hole wall of the mounting hole 1104 and the fixing part.

[0070] After inserting the fixing part into the through hole 1302, screw the connecting part into the screw hole in the fixing part to complete the assembly.

[0071] After assembly, the second rib 1324 is clamped between the head of the connecting component and the outer surface of the housing, and the first rib 1322 is clamped between the lower surface of the motor 120 and the inner surface of the housing. Thus, on the one hand, the first rib 1322 and the second rib 1324 absorb the impact force transmitted from the motor 120 to the housing to reduce working noise, and on the other hand, the first rib 1322 and the second rib 1324 achieve sealing on both the inner and outer sides.

[0072] As can be seen, by setting the pad 132 embedded in the mounting hole 1104 and the fixing part inserted into the pad 132, a nested assembly method is formed, thereby improving the radial assembly accuracy. On this basis, the positioning in the axial direction is supplemented by the screw-in connecting parts, so as to ensure that the motor 120 and the shock-absorbing component 130 can be accurately positioned in the predetermined position, thereby achieving the technical effect of improving the positioning accuracy of the motor 120 and the shock-absorbing component 130 and improving the structural stability of the smoke machine assembly 100.

[0073] As shown in Figures 11 and 12, in some embodiments of this application, optionally, the end of the through hole 1302 facing the outside of the volute 110 is the outlet 1304, and the end of the through hole 1302 facing the inside of the volute 110 is the inlet 1306; the diameter of the inlet 1306 is larger than the diameter of the outlet 1304.

[0074] In this embodiment, the through hole 1302 includes an inlet 1306 and an outlet 1304, wherein the inlet 1306 faces the inner side of the volute 110 and the outlet 1304 faces the outer side of the volute 110. The fixing part on the motor 120 is inserted into the through hole 1302 through the inlet 1306, and the connecting part is inserted into the through hole 1302 through the outlet 1304 and finally screwed into the screw hole on the fixing part.

[0075] Based on this, the diameter of the inlet 1306 is larger than the diameter of the outlet 1304, and the diameter of the through hole 1302 gradually decreases in the direction from the inlet 1306 to the outlet 1304.

[0076] By providing a larger inlet 1306, the difficulty of inserting the fixing part on the motor 120 into the through hole 1302 can be reduced, thereby reducing the assembly difficulty of the motor 120. By providing a smaller outlet 1304 and a through hole 1302 with a gradually decreasing diameter, the fixing part can compress the pad 132 during insertion into the through hole 1302. This allows the pad 132 to effectively fill the space between the fixing part and the wall of the mounting hole 1104, thereby improving the shock absorption effect of the pad 132 in the second direction and enhancing the sealing effect of the pad 132 between the mounting hole 1104 and the fixing part.

[0077] As shown in Figures 11 and 12, in some embodiments of this application, optionally, the outer diameter of the shock-absorbing component 130 is D0; the aperture of the outlet 1304 is D1, and D0 and D1 satisfy the relationship: 0.405≤D1÷D0≤0.477; the aperture of the inlet 1306 is D2, and D0 and D2 satisfy the relationship: 0.481≤D2÷D0≤0.543.

[0078] In this embodiment, the dimensions of the inlet 1306 and outlet 1304 of the through hole 1302 are defined.

[0079] D0 represents the outer diameter of the shock-absorbing component (130mm). D0 is an input condition, and D0 can be selected as 16mm.

[0080] D1 is the aperture of the 1304 outlet. 0.405≤D1÷D0≤0.477. Specifically, D1÷D0=0.45 can be selected, that is, D1=7.2mm.

[0081] D2 is the aperture of the 1306 inlet. 0.481≤D2÷D0≤0.543. Specifically, D2÷D0=0.49 can be selected, that is, D2=7.9mm.

[0082] By defining the above-mentioned dimensional relationship, the dimensional matching degree between the through hole 1302 and the fixing part on the motor 120 can be improved, thereby improving the shock absorption effect of the pad 132 in the second direction.

[0083] As shown in Figures 11 and 12, in some embodiments of this application, optionally, the thickness of the second rib 1324 is greater than or equal to the thickness of the first rib 1322.

[0084] In this embodiment, the axial direction of the through hole 1302 corresponds to the height direction of the damping component 130.

[0085] Based on this, the thickness of the second rib 1324 is greater than or equal to the thickness of the first rib 1322. The second rib 1324 is snapped onto the outside of the mounting hole 1104. By setting the second rib 1324 with a thickness greater than or equal to the first rib 1322, the second rib 1324 can withstand greater impact and bear greater stress, thereby improving the limiting reliability of the second rib 1324 on the pad 132, avoiding the first rib 1322 and the pad 132 from being misaligned towards the inside of the volute 110, and thus improving the absorption effect of the first rib 1322 and the pad 132 on vibration and impact.

[0086] As shown in Figures 11 and 12, in some embodiments of this application, optionally, the outer diameter of the damping component 130 is D0; the thickness of the damping component 130 is H0, and D0 and H0 satisfy the relationship: 0.59≤H0÷D0≤0.72; the thickness of the first rib 1322 is H1, and D0 and H1 satisfy the relationship: 0.17≤H1÷D0≤0.21; the thickness of the second rib 1324 is H2, and D0 and H2 satisfy the relationship: 0.28≤H2÷D0≤0.34.

[0087] In this embodiment, the thickness of the first rib 1322 and the second rib 1324 is defined.

[0088] D0 represents the outer diameter of the shock-absorbing component (130mm). D0 is an input condition, and D0 can be selected as 16mm.

[0089] H0 is the thickness of the damping component 130, 0.59≤H0÷D0≤0.72, specifically H0÷D0=0.66, that is, H0=10.5mm.

[0090] H1 is the thickness of the first rib 1322, 0.17≤H1÷D0≤0.21, specifically H1÷D0=0.19, that is, H1=3mm.

[0091] H2 is the thickness of the second rib 1324, 0.28≤H2÷D0≤0.34, specifically H2÷D0=0.31, that is, H2=5mm;

[0092] As shown in Figures 13, 14, and 15, the shape and dimensions of the vibration damping component 130 are designed according to the above design parameters and matching relationships. This not only isolates the axial vibration of the motor 120 but also isolates the vibration of the motor 120 in the second direction, thereby reducing the vibration acceleration of the range hood assembly 100 and the integrated stove 200 by 36% and the noise by 2.2 dB. This ultimately improves the operational reliability of the range hood assembly 100 and enhances the user experience.

[0093] As shown in Figures 6 and 8, in some embodiments of this application, optionally, the number of shock-absorbing components 130 is N, and the N shock-absorbing components 130 are evenly distributed around the mounting hole 1104, where N is an integer greater than or equal to 3.

[0094] In this embodiment, N damping components 130 are provided between the motor 120 and the volute 110, and the N damping components 130 are evenly distributed around the mounting hole 1104, that is, the included angle between two adjacent mounting holes 1104 is the same.

[0095] Where N is an integer greater than or equal to 3, specifically N can be 3, and the three mounting holes 1104 are distributed at 120° intervals.

[0096] By setting multiple shock-absorbing components 130, the vibration impact generated by the motor 120 on the volute 110 can be distributed, reducing the load on each shock-absorbing component 130. This improves the shock absorption effect of the shock-absorbing component 130 on the one hand, and reduces the probability of the shock-absorbing component 130 being damaged by the impact on the other hand.

[0097] By evenly distributing multiple damping components 130 around the mounting hole 1104, the uniformity of force distribution on the multiple damping components 130 can be improved, preventing damage to a particular damping component 130 due to uneven force distribution, thereby reducing the failure rate of the damping component 130.

[0098] As shown in Figures 3 and 4, in some embodiments of this application, optionally, the smoke hood assembly 100 further includes an impeller 140, which is disposed inside the volute 110 and connected to the motor 120.

[0099] In this embodiment, the range hood assembly 100 also includes an impeller 140. The power output end of the motor 120 is connected to the impeller 140. The motor 120 is used to drive the impeller 140 to rotate, so that the oil fumes are drawn into the volute 110 through the smoke inlet through the impeller 140, and after being pressurized and accelerated, the oil fumes are discharged from the volute 110 through the outlet 1304, thereby realizing the suction and centralized discharge of oil fumes.

[0100] As shown in Figures 1, 2 and 3, one embodiment of this application provides an integrated stove 200, which includes: a body 210, and a flue 2102 inside the body 210; as in any of the above embodiments of the range hood assembly 100, the volute 110 is connected to the body 210, and the cavity 1102 is connected to the flue 2102.

[0101] Arrow a in Figure 3 indicates the direction of oil fume flow.

[0102] In this embodiment, an integrated stove 200 is defined that is provided with the range hood component 100 in any of the above embodiments. Therefore, the integrated stove 200 has the advantages of the range hood component 100 in any of the above embodiments and can achieve the technical effects that the range hood component 100 in any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0103] Based on this, the integrated stove 200 includes a main body 210, within which a flue 2102 is formed. The integrated stove 200 can extract cooking fumes through the flue 2102 to collect the fumes and prevent them from spreading. A smoke inlet is provided at the top of the main body 210, which connects to the flue 2102. A grille 240 is embedded inside the smoke inlet to block foreign objects.

[0104] The integrated stove 200 also includes an grease separation component 220 and a filter component 230.

[0105] The grease separation component 220 is installed in the flue 2102, opposite to the smoke inlet on the flue 2102. After the fumes flow into the smoke inlet, they need to pass through the grease separation component first. The grease separation component 220 can separate the grease and water vapor mixed in the fumes, completing the pre-oil-water separation of the fumes. This prevents the fumes from carrying oil and water into the range hood component 100, thus protecting the range hood component 100 from oil and water contamination and extending the service life of the integrated stove 200. It also prevents the accumulation of oil and water in the flue 2102 from producing odors and avoids secondary pollution of the environment by the fumes processed by the integrated stove 200.

[0106] The filter assembly 230 is installed inside the flue 2102. The oil fumes flowing in the flue 2102 need to pass through the filter assembly 230 so that the oil fumes can be filtered by the filter components in the filter assembly 230 to reduce the odor of the oil fumes, avoid secondary pollution of the environment by oil fumes, and thus achieve the technical effect of improving the reliability of the integrated stove 200 and improving the user experience.
