Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a range hood and cooktop combo. Background Technology

[0002] In the relevant solutions, current market-available integrated range hoods and cooktops, by adding a fume extraction component to the cooktop, draw cooking fumes into the component through the fume extraction port on the cooktop. By removing oil and odors from the fumes, the fumes are transformed into clean air for release indoors or outdoors. This type of integrated range hood and cooktop takes up little space, is not restricted by shared exhaust ducts, and offers greater installation flexibility. It addresses the pain points of traditional range hoods and has therefore gained market and user acceptance.

[0003] However, in the relevant solutions, the fumes drawn in by the integrated range hood and cooktop often contain a large amount of water vapor. The water vapor is easily condensed into water inside the fume extraction component. In addition, soups and other liquids are prone to overflowing and entering the range hood's air intake. Furthermore, careless use by users may also cause water to be poured directly into the range hood's air intake. All of these methods will produce water inside the range hood.

[0004] Therefore, how to solve the wastewater problem in the integrated range hood and stove has become an urgent issue. Utility Model Content

[0005] This application aims to at least solve the technical problem of how to handle water generated inside integrated range hoods and cooktops in existing or related technologies.

[0006] Therefore, the purpose of this application is to propose an integrated range hood and cooktop unit.

[0007] An embodiment of this application provides a range hood and cooktop integrated unit, including: a cooktop with a smoke inlet; a fume extraction assembly including a smoke exhaust duct with an inlet connected to the smoke inlet, and a drain outlet connected to the smoke exhaust duct; and a wastewater box assembly connected to the fume extraction assembly, with a wastewater inlet connected to the drain outlet; the wastewater box assembly includes: a box body; and a cover mounted on the box body with a wastewater inlet connected to the interior of the box body.

[0008] The integrated range hood and cooktop provided in this application includes a cooktop, a range hood assembly, and a wastewater collection box assembly. The cooktop has a smoke extraction port. The exhaust duct inlet of the range hood assembly is connected to the smoke extraction port, and the range hood assembly also has a drain outlet connected to the exhaust duct. The wastewater collection box assembly is connected to the range hood assembly and has a wastewater inlet connected to the drain outlet. Through the drain outlet and wastewater collection box assembly, liquids that enter the range hood assembly due to condensation, spillage, or accidental operation can be effectively collected and discharged, preventing moisture accumulation from corroding the machine's interior or affecting normal operation, thereby improving product reliability and lifespan.

[0009] The wastewater box assembly mainly consists of a box body and a cover fitted onto it. The cover has a wastewater inlet that communicates with the inner cavity of the box. This structure effectively collects and guides wastewater through the cover, preventing liquid splashing or odor evaporation. The box body provides a sealed storage space for wastewater, ensuring hygiene and cleanliness during the collection process. It also facilitates the user's overall disassembly, cleaning, and maintenance of the wastewater box, significantly improving ease of use and ensuring the long-term cleanliness and reliability of the integrated range hood and stove.

[0010] Optionally, the fume extraction assembly includes: a housing, within which an exhaust duct is provided. The exhaust duct allows for the intake and exhaust of cooking fumes.

[0011] In the above embodiments, optionally, the fume extraction assembly further includes: a fan, which is rotatably disposed in the exhaust duct, and the rotation of the fan can draw fumes from the smoke inlet into the exhaust duct; wherein, the drain outlet is disposed on the outer casing, and the wastewater box assembly is installed on the outer casing and communicates with the drain outlet.

[0012] In this embodiment, the fume extraction assembly also includes a housing and a fan. The fan is rotatably disposed within the exhaust duct inside the housing to generate suction, drawing fumes from the stove's smoke inlet. A drain outlet is located on the housing, and a wastewater collection box assembly is installed on the housing and connected to the drain outlet. This solution, by directly placing the drain outlet on the housing containing the exhaust duct, efficiently collects the sucked-in condensate or overflow and directs it to the wastewater collection box assembly. This effectively prevents liquid from stagnating inside the exhaust duct or corroding the fan system, ensuring effective fume extraction and long-term stability of the equipment.

[0013] Optionally, a portion of the outer casing is located inside the cooktop, and the inlet of the exhaust duct is located on the part of the outer casing inside the cooktop.

[0014] In this embodiment, a portion of the outer casing and its exhaust duct inlet are integrated into the cooktop, bringing the smoke inlet closer to the source of cooking fumes. This design shortens the smoke intake path and improves smoke extraction efficiency. Simultaneously, the built-in structure not only reduces the overall volume but also helps collect condensate and discharge it through the duct, effectively preventing oil buildup and moisture overflow, keeping the cooktop surface clean, and enhancing the product's integrated design and aesthetics.

[0015] In the above embodiments, optionally, the drain outlet is located at the bottom of the housing, and the wastewater box assembly is installed at the bottom of the housing.

[0016] In this embodiment, the drain outlet is located at the bottom of the housing, and the wastewater box assembly is correspondingly installed at the bottom of the housing. This design utilizes gravity to allow condensate generated inside the fume extraction assembly or any accidentally introduced liquid to naturally collect at the lowest point of the drain outlet and flow directly into the wastewater box. This achieves efficient and automatic wastewater collection and discharge, reduces maintenance frequency and the risk of internal water accumulation, and ensures the long-term reliable operation and convenient cleaning of the equipment.

[0017] In the above embodiments, optionally, the integrated range hood and cooktop further includes: a grease filter device disposed inside the outer casing for separating smoke and grease, the grease filter device having a drain channel; a purification device disposed inside the outer casing and located on the smoke outlet side of the grease filter device; and a drainage channel, the inlet of the drainage channel being connected to the drain channel and the outlet of the drainage channel being connected to the drain outlet.

[0018] In this embodiment, the integrated range hood and cooktop also includes a grease filter, a purification device, and a drainage channel housed within the outer casing. The grease filter separates and collects grease from the flue gas and discharges it through its drain channel; the purification device, located on the flue gas outlet side, further purifies the separated flue gas; and the drainage channel guides the waste liquid discharged from the drain channel to the drain outlet on the outer casing. This design achieves effective separation and collection of grease and condensate, preventing oil-water mixtures from clogging the air ducts or corroding internal components, significantly improving the efficiency of fume purification, and reducing the complexity of equipment maintenance.

[0019] In the above embodiments, optionally, the smoke outlet side of the grease filter is located on the periphery of the grease filter, and the outlet of the drain channel is located at the bottom of the grease filter.

[0020] In this embodiment, the smoke outlet of the grease filter is located on its periphery, while the drain outlet is located at its bottom. This layout allows the separated grease and condensate to naturally collect by gravity and be discharged centrally from the bottom, while the purified smoke flows smoothly from the periphery to the next stage of purification. This design optimizes the gas-liquid separation path, significantly improves liquid collection efficiency and emission reliability, and ensures long-term stable purification performance and lower maintenance requirements for the integrated range hood and cooktop.

[0021] In the above embodiments, optionally, at least a portion of the wastewater box assembly is a transparent structure. The transparent structure allows the user to easily observe the internal structure of the wastewater box assembly, thus facilitating timely cleaning.

[0022] In the above embodiments, optionally, the wastewater box assembly further includes a sealing ring disposed between the box body and the cover for sealing the gap between the box body and the cover.

[0023] In this embodiment, a sealing ring is added between the box and the cover to effectively seal the assembly gap between them. This design prevents sewage or odors from leaking from the seams, ensuring a completely sealed sewage collection process. This not only improves the product's hygiene level and avoids secondary pollution, but also effectively protects the internal components of the machine from moisture corrosion, further enhancing the reliability and service life of the equipment. At the same time, it facilitates overall disassembly and cleaning maintenance for users.

[0024] In the above embodiments, optionally, an annular baffle is provided on the cover and around the sewage inlet, and the annular baffle is sealed to the fume extraction assembly.

[0025] In this embodiment, an annular baffle is provided around the sewage inlet of the cover, and the annular baffle forms a sealed connection with the corresponding part of the fume extraction component. This structure adds a reliable sealing barrier to the sewage inflow path, which can completely prevent liquid or oil vapor from leaking from the interface gaps, effectively avoiding internal component corrosion and odor diffusion problems caused by leakage, and significantly improving the product's sealing reliability, hygiene level and user experience.

[0026] In the above embodiments, optionally, a first guide rib extending toward the box body is provided on the periphery of the cover and the sewage inlet, and at least a portion of the first guide rib is located inside the box body.

[0027] In this embodiment, a first guide rib extending into the interior of the casing is provided around the periphery of the sewage inlet of the cap, and at least a portion of the first guide rib extends into the interior of the casing. This structure can effectively guide and buffer the flowing liquid, preventing splashing, backflow, or air bubbles that may be caused by impact during sewage injection, ensuring that the liquid flows smoothly and directionally into the bottom of the casing, thereby further improving the sealing and hygiene of the sewage collection process, as well as the convenience and cleanliness of user maintenance.

[0028] In the above embodiments, optionally, the integrated range hood and stove also includes a second guide rib, which is disposed on the oil fume extraction assembly and located on the periphery of the drain outlet, with at least a portion of the second guide rib inserted into the sewage inlet.

[0029] In this embodiment, the integrated range hood and cooktop also includes a second guide rib disposed around the drain outlet of the fume extraction component, with at least a portion of the second guide rib inserted into the wastewater inlet of the wastewater box component. This structure forms a directional guide channel between the drain outlet and the wastewater inlet, which can precisely guide wastewater from the fume extraction component into the wastewater box, effectively preventing liquid from dripping, splashing, or accumulating at the interface, significantly improving the sealing reliability and cleanliness of the drainage process, while avoiding corrosion or odor problems that may be caused by liquid residue.

[0030] In the above embodiments, optionally, when the cover is provided with an annular baffle, the annular baffle is provided at the edge of the sewage inlet, and the inner side of the annular baffle is aligned with the inner sidewall of the sewage inlet.

[0031] In this embodiment, an annular baffle is disposed at the edge of the sewage inlet, and its inner side is precisely aligned with the inner wall of the sewage inlet. This structure allows the annular baffle and the sewage inlet to form a smooth and continuous flow guiding surface, achieving efficient sealing while ensuring that liquid can flow directly into the sewage box without obstruction.

[0032] In the above embodiments, optionally, when the cover is provided with a first guide rib, the first guide rib is provided at the edge of the sewage inlet, and the inner side of the first guide rib is aligned with the inner sidewall of the sewage inlet.

[0033] In this embodiment, the first guide rib is disposed at the edge of the sewage inlet, and its inner side is precisely aligned with the inner wall of the sewage inlet. This structure enables the first guide rib to form a smooth and continuous guiding surface with the sewage inlet, ensuring that the liquid can be concentrated and smoothly guided into the box while maintaining efficient sealing. This effectively avoids liquid splashing, retention or leakage that may be caused by structural abrupt changes, and significantly improves the guiding nature, sealing reliability and overall hygiene level of the drainage process.

[0034] In the above embodiments, optionally, at least a portion of the cover is recessed toward the box body to form a recessed portion, at least a portion of the recessed portion is installed inside the box body, and the sewage inlet is disposed on the recessed portion.

[0035] In this embodiment, at least a portion of the cap is recessed towards the box body to form a recessed portion. At least a portion of the recessed portion is installed inside the box body, and the sewage inlet is located on the recessed portion. This structure, through the extended design of the recessed portion, effectively shortens the path of sewage flowing into the box body, significantly reducing the risk of liquid splashing and overflow. At the same time, it enhances the connection strength and sealing effect between the cap and the box body, further ensuring the hygiene, reliability, and ease of maintenance for the sewage collection process.

[0036] In the above embodiments, optionally, a reinforcing rib is provided on the recessed portion, and the reinforcing rib is provided on the surface of the recessed portion away from the sewage box assembly.

[0037] In this embodiment, a reinforcing rib is provided on the recessed portion, and the reinforcing rib is located on the outer surface of the recessed portion away from the box body. This structure significantly enhances the structural rigidity and deformation resistance of the recessed portion without occupying almost any internal space or affecting the sewage flow path. It effectively avoids the deformation of the cover caused by external pressure or temperature changes, thereby ensuring the long-term sealing reliability between the sewage inlet and the outlet, and further improving the structural stability and service life of the product.

[0038] In the above embodiments, optionally, the wastewater box assembly is provided with a first thread, and the fume extraction assembly is provided with a second thread.

[0073] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be 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 the embodiments of this application can be combined with each other.

[0074] 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.

[0075] The following reference Figures 1 to 27 This application describes a range hood and cooktop integrated unit provided according to some embodiments.

[0076] like Figure 1 , Figure 2 , Figure 5 , Figure 13 and Figure 25 As shown, the integrated range hood and stove provided in this application includes a stove 1, a fume extraction component 2, and a wastewater box component 5. The stove 1 is provided with a smoke extraction port 12; the exhaust duct 28 of the fume extraction component 2 is connected to the smoke extraction port 12, and the fume extraction component 2 is provided with a drain outlet 220 connected to the exhaust duct 28; the wastewater box component 5 is connected to the fume extraction component 2 and is provided with a wastewater inlet 50 connected to the drain outlet 220.

[0077] The integrated range hood and stove provided by this utility model, through the cooperation of the drain outlet 220 and the sewage box component 5, can effectively collect and discharge the liquid that enters the inside of the range hood component 2 due to condensation, overflow, or misoperation, and avoid moisture accumulation that may cause corrosion inside the machine or affect normal operation, thereby improving the reliability and service life of the product.

[0078] Optionally, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the wastewater box assembly 5 mainly consists of a box body 52 and a cover 54 mounted on it. The cover 54 has a wastewater inlet 50 that communicates with the inner cavity of the box body 52. ​​This structure effectively collects and guides wastewater through the cover 54, preventing liquid splashing or odor evaporation. The box body 52 provides a sealed storage space for wastewater, ensuring hygiene and cleanliness during the collection process. This design facilitates the user's overall disassembly, cleaning, and maintenance of the wastewater box, significantly improving ease of use and ensuring the long-term cleanliness and reliability of the integrated range hood and stove.

[0079] In the above embodiments, optionally, as shown... Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 27 As shown, the fume extraction assembly 2 also includes a housing 22. An exhaust duct 28 is disposed within the housing 22. A portion of the housing 22 is located inside the cooktop 1, and the inlet of the exhaust duct 28 is located on the portion of the housing 22 located inside the cooktop 1.

[0080] In this embodiment, a portion of the outer shell 22 of the fume extraction assembly 2 and its exhaust duct 28 inlet are integrated into the interior of the cooktop 1, bringing the fume extraction port 12 closer to the source of the fumes. This design shortens the path of the fumes and improves the fume extraction efficiency. Simultaneously, the built-in structure not only reduces the overall volume but also helps collect the generated condensate and discharge it through the duct, effectively preventing oil buildup and water vapor overflow, keeping the surface of the cooktop 1 clean, and enhancing the product's integration and aesthetics.

[0081] Optionally, such as Figure 3 , Figure 4 , Figure 24 and Figure 25 As shown, the fume extraction assembly 2 also includes a fan 21, which is rotatably mounted in the exhaust duct 28 within the housing 22 to generate suction that draws fumes from the smoke inlet 12 of the stove 1. A drain outlet 220 is located on the housing 22, and a wastewater box assembly 5 is installed on the housing 22 and connected to the drain outlet 220. This design, by directly placing the drain outlet 220 on the housing 22 where the exhaust duct 28 is located, can efficiently collect the sucked-in condensate or overflow and direct it to the wastewater box assembly 5. This effectively prevents liquid from stagnating inside the duct or corroding the fan 21, ensuring effective fume extraction and long-term stability of the equipment.

[0082] Optionally, the fan 21 includes a fan wheel 212 and a motor 214.

[0083] in, Figure 25 The straight arrows in the image indicate the flow path of the cooking fumes.

[0084] In the above embodiments, optionally, as shown... Figure 3 and Figure 22 As shown, the drain outlet 220 is located at the bottom of the housing 22, and the wastewater box assembly 5 is correspondingly installed at the bottom of the housing 22. This design utilizes gravity to allow condensate generated inside the fume extraction assembly 2 or any accidentally entering liquid to naturally collect at the lowest point, drain outlet 220, and flow directly into the wastewater box. This achieves efficient and automatic wastewater collection and discharge, significantly reducing maintenance frequency and the risk of internal water accumulation, ensuring the equipment's long-term reliable operation and convenient cleaning.

[0085] In the above embodiments, optionally, as shown... Figure 3 , Figure 21 , Figure 23 , Figure 25 and Figure 27As shown, the integrated range hood and cooktop also includes a grease filter 3, a purification device 4, and a drainage channel 7. The grease filter 3 is located inside the outer casing 22 and is used to separate smoke and grease. A drain channel 30 is provided on the grease filter 3. The purification device 4 is located inside the outer casing 22 and is located on the smoke outlet side of the grease filter 3. The inlet of the drainage channel 7 is connected to the drain channel 30, and the outlet of the drainage channel 7 is connected to the drain outlet 220.

[0086] In this embodiment, the integrated range hood and cooktop also includes a grease filter 3, a purification device 4, and a drainage channel 7 disposed within the outer casing 22. The grease filter 3 separates and collects the grease in the flue gas and discharges it through its drain channel 30; the purification device 4, located on its smoke outlet side, further purifies the separated flue gas; and the drainage channel 7 guides the waste liquid discharged from the drain channel 30 to the drain outlet 220 of the outer casing 22. This design achieves effective separation and collection of grease and condensate, preventing oil-water mixtures from clogging the air duct or corroding internal components, significantly improving the efficiency of fume purification, and reducing the maintenance complexity of the equipment.

[0087] In the above embodiments, optionally, as shown... Figure 3 , Figure 4 and Figure 23 As shown, the smoke outlet of the grease filter 3 is located on its periphery, while the outlet of the drain channel 30 is located at its bottom. This layout allows the separated grease and condensate to naturally collect by gravity and be discharged centrally from the bottom, while the purified smoke flows smoothly from the periphery to the next-stage purification device 4. This design optimizes the gas-liquid separation path, improves liquid collection efficiency and emission reliability, and ensures long-term stable purification performance and lower maintenance requirements for the integrated range hood and cooktop.

[0088] in, Figure 3 and Figure 4 The straight arrows in the diagram indicate the discharge path of the sewage within the sewage box assembly 5.

[0089] In the above embodiments, optionally, at least a portion of the wastewater box assembly 5 is a transparent structure. The transparent structure allows the user to easily observe the interior of the wastewater box assembly 5, thereby facilitating timely cleaning of the assembly.

[0090] In the above embodiments, optionally, as shown... Figure 14 As shown, the wastewater box assembly 5 also includes a sealing ring 56. The sealing ring 56 is disposed between the box body 52 and the cover 54 to seal the gap between the box body 52 and the cover 54.

[0091] In this embodiment, a sealing ring 56 is added between the box body 52 and the cover 54 to effectively seal the assembly gap between them. This prevents sewage or odor from leaking from the joint, ensuring a completely sealed sewage collection process. This not only improves the hygiene level of the product and avoids secondary pollution, but also effectively protects the internal components of the machine from moisture corrosion, further enhancing the reliability and service life of the equipment. At the same time, it facilitates the user's overall disassembly and cleaning maintenance.

[0092] In the above embodiments, optionally, as shown... Figure 11 , Figure 12 and Figure 13 As shown, annular baffles 542 are provided on the cover 54 and around the sewage inlet 50, and the annular baffles 542 are sealed to the fume extraction assembly 2.

[0093] In this embodiment, an annular baffle 542 is provided around the sewage inlet 50 of the cover 54, and the annular baffle 542 forms a sealed connection with the corresponding part of the fume extraction assembly 2. This structure adds a reliable sealing barrier to the sewage inflow path, which can completely prevent liquid or oil vapor from leaking from the interface gaps, effectively avoiding the problems of internal component corrosion and odor diffusion caused by leakage, and significantly improving the sealing reliability, hygiene level and user experience of the product.

[0094] In the above embodiments, optionally, as shown... Figure 12 , Figure 13 and Figure 15 As shown, the sewage inlet 50 of the cover 54 is provided with a first guide rib 546 extending into the interior of the box 52, and at least a portion of the first guide rib 546 extends into the interior of the box 52. This structure can effectively guide and buffer the flowing liquid, effectively preventing splashing, backflow, or air bubbles that may be caused by impact during sewage injection, ensuring that the liquid flows smoothly and directionally into the bottom of the box 52, thereby further improving the sealing and hygiene of the sewage collection process, as well as the convenience and cleanliness of user maintenance.

[0095] In the above embodiments, optionally, as shown... Figure 13 As shown, the integrated range hood and cooktop also includes a second guide rib 228 disposed around the drain outlet 220 of the range hood assembly 2, with at least a portion of the second guide rib 228 inserted into the wastewater inlet 50 of the wastewater box assembly 5. This structure forms a directional guide channel between the drain outlet 220 and the wastewater inlet 50, which can accurately guide wastewater from the range hood assembly 2 into the wastewater box, effectively preventing liquid from dripping, splashing, or accumulating at the interface, significantly improving the sealing reliability and cleanliness of the drainage process, while avoiding corrosion or odor problems that may be caused by liquid residue.

[0096] In the above embodiments, optionally, the annular baffle 542 is disposed at the edge of the sewage inlet 50, and its inner side is precisely aligned with the inner wall of the sewage inlet 50. This structure makes the annular baffle 542 and the sewage inlet 50 form a smooth and continuous flow guiding surface, which ensures that the liquid can flow directly into the sewage box without obstruction while achieving efficient sealing.

[0097] In the above embodiments, optionally, the first guide rib 546 is disposed at the edge of the sewage inlet 50, and its inner side is precisely aligned with the inner wall of the sewage inlet 50. This structure makes the first guide rib 546 and the sewage inlet 50 form a smooth and continuous guiding surface, ensuring that the liquid can be concentrated and smoothly introduced into the box 52 while maintaining efficient sealing. This effectively avoids liquid splashing, retention or leakage that may be caused by structural abrupt changes, and significantly improves the guiding nature, sealing reliability and overall hygiene level of the drainage process.

[0098] In the above embodiments, optionally, as shown... Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, at least a portion of the cover 54 is recessed towards the box body 52 to form a recess 540. At least a portion of the recess 540 is inserted into the box body 52, and the sewage inlet 50 is located on the recess 540. This structure, through the extended design of the recess 540, effectively shortens the path of sewage into the box body 52, significantly reducing the risk of liquid splashing and overflow. At the same time, it enhances the connection strength and sealing effect between the cover 54 and the box body 52, further ensuring the hygiene, reliability, and ease of maintenance for the sewage collection process.

[0099] In the above embodiments, optionally, as shown... Figure 18 As shown, a reinforcing rib 58 is provided on the recessed portion 540, and the reinforcing rib 58 is located on the outer surface of the recessed portion 540 away from the box body 52. ​​This structure significantly enhances the structural rigidity and deformation resistance of the recessed portion 540 without occupying much internal space or affecting the sewage flow path. It effectively avoids deformation of the cover 54 caused by external pressure or temperature changes, thereby ensuring the long-term sealing reliability between the sewage inlet 50 and the drain outlet 220, and further improving the structural stability and service life of the product.

[0100] Optionally, there are multiple reinforcing ribs 58, which are spaced apart circumferentially along the sewage inlet 50, with each reinforcing rib 58 extending from the center of the recess 540 toward the edge. The multiple reinforcing ribs 58 are arranged radially on the cover 54.

[0101] In the above embodiments, optionally, as shown... Figures 1 to 4 , Figure 19 and Figure 20As shown, the wastewater box assembly 5 is provided with a first thread 59, and the fume extraction assembly 2 is provided with a second thread. The wastewater box assembly 5 is screwed onto the fume extraction assembly 2 through the cooperation of the first thread 59 and the second thread.

[0102] In this embodiment, the wastewater box assembly 5 and the fume extraction assembly 2 are screwed together by the engagement of a first thread 59 and a second thread on both. This threaded connection provides users with a simple and secure assembly solution, ensuring that the wastewater box will not loosen or fall off due to vibration or external impact during operation. Simultaneously, the threaded interface itself has excellent sealing performance, effectively preventing wastewater leakage and significantly improving the product's reliability, safety, and ease of maintenance for users.

[0103] In the above embodiments, optionally, the wastewater box assembly 5 is located on the user operation side of the stove 1, that is, the side of the stove 1 closest to the user for easy operation. This layout allows the user to easily observe the status of the wastewater box and disassemble and clean it during cooking without moving the machine or bending over, greatly improving the convenience of maintenance and user experience.

[0104] Optionally, such as Figure 24 As shown, the height of the wind turbine 212 is h, and the diameter of the wind turbine 212 is more than 5 times the height h.

[0105] Optionally, such as Figure 23 As shown, the integrated range hood and cooktop also includes a protective frame 6, which is positioned between the grease filter device 3 and the outer casing 22, and the protective frame 6 is provided with an air passage. The protective frame 6 can shield the smoke inlet 222, thereby preventing the user from contacting the operating impeller 212.

[0106] In these technical solutions, the protective frame 6 can shield the smoke inlet 222, thereby preventing the user from contacting the operating impeller. At the same time, in order to ensure the passage of smoke, an air passage is provided on the protective frame so that the oil fumes drawn in from the smoke inlet 12 can pass through the protective frame 6 and enter the outer casing 22.

[0107] Optionally, such as Figures 1 to 4 as well as Figure 23 As shown, the outer casing 22 includes a volute 24 and a top cover 26. A fan 21 is installed in the volute 24, and a grease filter 3 and a purification device 4 are installed in the top cover 26. The volute 24 and the top cover 26 form an exhaust duct 28. The inlet of the exhaust duct 28 forms a smoke inlet 222, which is located on the top cover 26. The outlet of the exhaust duct 28 forms a smoke outlet 224, which is located on the volute 24.

[0108] Optionally, such as Figure 25 , Figure 26 and Figure 27As shown, the integrated range hood and cooktop also includes a flue pipe 29, which is connected to a smoke outlet 224 for discharging filtered and purified fumes.

[0109] Optionally, such as Figure 26 As shown, the volute 24 is provided with a clearance notch 226, and a part of the flue 29 is installed at the clearance notch 226.

[0110] Optionally, the first section of the flue 29 is connected to the smoke outlet 224 and extends radially along the fan 21, while the second section of the flue 29 is connected to the first section and extends along the height of the stove 1; wherein at least a portion of the second section of the flue 29 is located within the clearance notch 226. The flue 29 includes a first section and a second section. The first section is arranged laterally and is connected to the smoke outlet 224 of the fan 21 housing. The second section is connected to the first section and extends along the height of the flue 29, i.e., the flue 29 is approximately L-shaped, which reduces the lateral width occupied by the flue 29. This allows for an increase in the lateral width of the impeller 212 while avoiding installation interference caused by excessively increasing the overall thickness of the unit due to setting the flue 29 to be straight (i.e., non-bent), and also ensures that a large cross-sectional area flue 29 can be used without sacrificing the flow area to control the overall thickness of the unit.

[0111] in, Figures 1 to 27 The curved arrow in the image indicates the direction of rotation of wind turbine 212.

[0112] The following describes a specific embodiment of the integrated range hood and cooktop.

[0113] Currently, integrated range hoods and cooktops on the market incorporate a fume extraction component on the cooktop. This component draws cooking fumes into the cooktop through the air inlet on the cooktop panel, removing oil and odors, and then purifying the fumes into clean air before releasing them indoors or outdoors. These integrated range hoods and cooktops occupy little space, are not restricted by shared exhaust ducts, and offer greater installation flexibility. They address the pain points of traditional range hoods, thus gaining market and user acceptance.

[0114] However, the integrated fume extraction system in the relevant solutions still has the following drawbacks:

[0115] The fumes drawn in by range hoods often contain a large amount of water vapor, which easily condenses into water inside the hood. Additionally, soups and other liquids can easily overflow and enter the range hood's air intake. Furthermore, careless use by users can also result in water being poured directly into the air intake. All these factors contribute to water production inside the range hood, making it necessary to collect the wastewater inside.

[0116] Because the wastewater box component of a combined range hood and stove is usually placed under the stove body or inside the cabinet, users cannot usually see the specific condition of the wastewater box component. When they do occasionally observe the wastewater box component, it is usually already quite full of wastewater and oil. In addition, the wastewater box component is usually placed inside the cabinet, making it inconvenient to take it out and clean it. As a result, when users take it out to clean the wastewater box component, their hands often shake or move, causing the wastewater and oil to spill out of the wastewater box component, making the user's hands, cabinets, floors, etc., resulting in a very poor user experience.

[0117] In addition, wastewater box components are often designed to be open, and there is a certain probability that mosquitoes will fall into the wastewater box components, causing a worse user experience.

[0118] In conclusion, an effective technical solution is needed to at least partially solve the above problems.

[0119] Based on the above requirements, such as Figures 1 to 27 As shown, this embodiment provides a range hood and cooktop integrated unit with a wastewater box assembly 5. The integrated unit includes a box body 52 and a cover 54. The cover 54 has a small flow hole for the flow of wastewater, oil, etc. When the wastewater box assembly 5 is removed for cleaning, the cover 54 prevents the wastewater from sloshing, thus preventing spillage. The cover 54 also has a certain sealing effect, which can contain the odor of the wastewater to a certain extent and also prevent mosquitoes from entering the interior of the wastewater box assembly 5.

[0120] In one specific embodiment, the sewage box assembly 5 includes a box body 52 and a cover 54, with the cover 54 having a flow hole.

[0121] Specifically, the small opening of the cap 54 is provided with upward-extending ribs, which fit or seal against the top to prevent odors (in conjunction with the flow channel).

[0122] Specifically, sealing strips are added around the 54-sealed area to further prevent spillage.

[0123] Specifically, the cap 54 is submerged below the opening of the box to further prevent spillage.

[0124] Specifically, the sewage box assembly 5 is fixed by connecting it to the volute using threads.

[0125] Specifically, the wastewater box assembly 5 is located on the user's operating side, making it easier for the user to observe, pick up, and place the wastewater box.

[0126] in, Figure 1 This is a view of the overall appearance of the integrated range hood and cooktop, including the cooktop body (i.e., cooktop 1) and the fume extraction component 2.

[0127] Figure 2 This is an exploded view of the integrated range hood and cooktop. The integrated range hood and cooktop consists of the cooktop body and the fume extraction component 2. The fume extraction component 2 includes a grease filter device 3. The cooktop body includes the cooktop panel and heating elements.

[0128] Figure 3 and Figure 4 This is a cross-sectional view of the integrated range hood and stove, with straight arrows indicating the direction of wastewater flow. Wastewater and oil drip through the grease filter 3 onto the volute (i.e., outer casing 22). The volute is equipped with a wastewater flow channel, which guides the wastewater and oil to the top of the wastewater box assembly 5, through the pre-set flow holes on the cover 54, and then drips into the wastewater box assembly 5 for collection.

[0129] like Figures 5 to 21 As shown, the wastewater box assembly 5 consists of a box body 52 and a cover 54. The wastewater box assembly 5 is used to collect wastewater and oil and is connected and fixed to the volute. The cover 54 covers the upper opening of the box body 52 and has a flow hole for the flow of wastewater and oil.

[0130] The box body 52 and the cover 54 are designed to fit together and can be disassembled.

[0131] The container 52 can be made of plastic, glass, or metal. For example, the container 52 is made of a transparent material to allow the user to observe the sewage inside.

[0132] The material of the cap 54 can be silicone, rubber, plastic, glass, metal, etc. For example, the material of the cap 54 is silicone or rubber to ensure that the cap 54 has good sealing performance.

[0133] like Figure 10 and Figure 11 As shown, a guide rib (i.e., annular baffle 542) is added to the upper side of the cover 54, which corresponds to the center of the liquid flow hole of the upper volute, and only leaves a small gap or fits tightly to seal with the upper part, so as to further prevent spillage and odor (in combination with the flow channel).

[0134] For example, the guide rib can extend to the lower side of the cover 54 to form a first guide rib 546, which can guide the oil stains, making the oil stains easier to collect.

[0135] For example, the leakage hole corresponding to the volute can also be made into a guide ring (i.e., the second guide rib 228) and embedded in the guide rib of the cover 54, which is more conducive to collecting sewage.

[0136] like Figure 14 As shown, at the connection between the box body 52 and the cover 54, a sealing strip (i.e., sealing ring 56) is added around the perimeter for sealing, which can further prevent spillage. The sealing strip can be made of silicone, rubber, sponge, or other materials.

[0137] like Figure 16As shown, the cover 54 is submerged at a certain distance L below the top of the opening of the box 52. When it is taken out or placed, the sewage in the box 52 shakes and first comes into contact with the cover 54. Due to the obstruction of the cover 54 and the surface tension and capillary action, the sewage first adheres to the lower surface of the cover 54 and then reaches the top edge of the sewage box assembly 5. This can further prevent spillage.

[0138] For example, such as Figures 14 to 19 As shown, a reinforcing rib 58 can be added to the upper side of the cover 54 to ensure the strength of the cover 54.

[0139] For example, such as Figures 19 to 21 As shown, the wastewater box assembly 5 is fixed to the volute housing using threads. Compared to snap-fit ​​or sliding groove connections, the threaded connection allows for a certain amount of disengagement force when the wastewater box assembly 5 is handled, causing it to shake and potentially spill. With a threaded connection, the force required for loosening and tightening is smoother, resulting in less shaking and less spillage.

[0140] For example, the wastewater box assembly 5 is located on the user's operating side, making it easier for the user to observe and handle.

[0141] Based on the above solution, the following beneficial effects can be achieved:

[0142] 1. When the sewage box assembly 5 is disassembled for cleaning, the cover 54 prevents the sewage from shaking, thus preventing spillage when taking it out. The cover 54 also has a certain sealing effect, which can seal the odor of the sewage to a certain extent and prevent mosquitoes from entering the sewage box assembly 5.

[0143] 2. The threaded connection allows for smoother rotation and tightening, resulting in less shaking of the wastewater box assembly 5 and reducing the likelihood of spillage.
