Description

Technical Field

[0001] This utility model relates to an integrated stove, belonging to the technical field of kitchen appliances. Background Technology

[0002] Internal circulation integrated cooktops are characterized by their ability to operate without external ducts and their flexible installation. These cooktops typically draw cooking fumes into the cooktop through a fume hood, where they are purified by internal filters before being exhausted back into the kitchen through vents on the countertop. However, this system places extremely high demands on the performance of the internal filtration system. Insufficient filtration will result in unremoved cooking particles and odors being re-introduced into the room, exacerbating kitchen pollution. Current technology for this type of integrated cooktop often suffers from problems such as a single filtration level, easy grease buildup affecting fan efficiency, and inconvenient maintenance. These issues lead to a decline in filtration effectiveness over long-term use, making it difficult to guarantee stable exhaust air quality. Utility Model Content

[0003] The purpose of this invention is to provide an integrated stove that can improve the filtration effect of oil fumes, resulting in cleaner exhaust air.

[0004] This utility model is achieved through the following technical solution.

[0005] An integrated stove includes a smoke inlet duct, a smoke collection chamber with a built-in fan assembly, a smoke exhaust duct, and an air outlet chamber, which are arranged in sequence inside the stove. The smoke inlet duct is provided with a pre-filter layer for pre-filtering the oil fumes entering the smoke collection chamber, and the smoke exhaust duct is provided with a post-filter layer for post-filtering the oil fumes exiting the smoke collection chamber. The smoke inlet duct has an opening on the stove surface, and a smoke collection hood for drawing in oil fumes is provided at the opening. The air outlet chamber has an air outlet on the stove surface for discharging clean air.

[0006] As a further improvement of this utility model, the cross-sectional area of ​​the flue gradually increases from its inlet end to its outlet end.

[0007] As a further improvement of this utility model, the rear filter layer is arranged at the exhaust end of the flue.

[0008] As a further improvement of this utility model, multiple baffles are provided on the end face of the exhaust duct outlet to form multiple slots on the end face of the exhaust duct outlet, and the rear filter layer includes multiple filter plates inserted into each slot.

[0009] As a further improvement of this utility model, the fan assembly includes a fan housing, an impeller disposed inside the fan housing, and a driver for driving the impeller. The fan housing has a fan inlet for guiding oil fumes into the smoke inlet duct and a fan outlet for discharging oil fumes to the exhaust duct. The fan housing is provided with multiple noise reduction holes and its outer wall is covered with a mesh porous structure layer. The mesh porous structure layer is used to absorb noise and absorb grease in the oil fumes and drop it to the bottom of the smoke collection chamber.

[0010] As a further improvement of this utility model, the mesh porous structure layer is covered with a solid layer to prevent air leakage from the fan casing.

[0011] As a further improvement of this utility model, an oil leakage hole is provided at the bottom of the fan housing to drain the grease inside the fan housing to the bottom of the smoke collection chamber.

[0012] As a further improvement of this utility model, a drain pipe is connected to the bottom of the smoke collection chamber and the side of the air outlet chamber. The drain pipe is used to discharge the grease in the smoke collection chamber to the air outlet chamber. An oil cup is provided in the air outlet chamber to collect the grease discharged into the air outlet chamber by the drain pipe.

[0013] As a further improvement of this utility model, the bottom of the smoke collection chamber has a downwardly recessed oil collection groove for collecting grease that drips to the bottom of the smoke collection chamber, and the position where the drain pipe connects to the bottom of the smoke collection chamber corresponds to the oil collection groove.

[0014] As a further improvement of this utility model, the smoke collection chamber is equipped with a filter component for preliminary filtration of the inhaled oil fumes.

[0015] The beneficial effects of this utility model are:

[0016] The initial filter layer is located at the initial stage of oil fume entry, which can intercept most of the grease and particulate matter, reducing the load on the subsequent smoke collection chamber and fan components. The final filter layer is located at the final stage of oil emission, which thoroughly purifies the air. Thus, the overall filtration efficiency is improved through dual filtration. The arrangement of the initial and final filter layers avoids the problem of non-compliance with emission standards caused by the failure of a single filter layer, enabling the integrated stove to continuously output clean air in internal circulation mode and improve the kitchen environment.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0023] This embodiment illustrates an integrated stove, with reference to... Figures 1-3 The integrated stove mainly includes a smoke inlet duct 2, a smoke collection chamber 3 with a built-in fan assembly, a smoke exhaust duct 5, and an air outlet chamber 6, all arranged sequentially inside the stovetop. The smoke inlet duct 2 has an opening on the stovetop surface, and a smoke collection hood 1 is installed at the opening to draw in the fumes generated during cooking. The smoke collection hood 1 is height-adjustable to accommodate cookware of different heights and different cooking scenarios. The air outlet chamber 6 has an air outlet 61 on the stovetop surface to discharge filtered clean air. A pre-filter layer a1 is installed inside the smoke inlet duct 2. This filter layer is made of porous filter material such as metal mesh or activated carbon fiber, which is used to pre-filter the fumes before they enter the smoke collection chamber 3, capturing larger particles and grease in the fumes. A post-filter layer a2 is installed inside the smoke exhaust duct 5, also made of porous filter material such as metal mesh or activated carbon fiber, which is used to post-filter the fumes after they exit the smoke collection chamber 3, further removing fine particles and residual grease. The smoke collection chamber 3 houses a built-in fan assembly, which drives the fumes from the inlet duct 2 through the smoke collection chamber 3 to the exhaust duct 5 and the outlet chamber 6. The initial filter layer a1 is located at the initial stage of fumes entering the chamber, intercepting most of the grease and particulate matter, reducing the load on the subsequent smoke collection chamber 3 and the fan assembly. The final filter layer a2 is located at the final stage of fumes discharge, thoroughly purifying the air. This dual filtration improves the overall filtration efficiency. The arrangement of the initial filter layer a1 and the final filter layer a2 avoids the problem of substandard emissions caused by the failure of a single filter layer, enabling the integrated stove to continuously output clean air in internal circulation mode and improve the kitchen environment.

[0024] In this embodiment, considering the flow efficiency of the exhaust duct 5, the cross-sectional area of ​​the exhaust duct 5 gradually increases from its inlet end to its outlet end. Specifically, the exhaust duct 5 is configured as a conical or trumpet-shaped structure. The inlet end connects to the outlet of the smoke collection chamber 3 and has a smaller cross-sectional area, while the outlet end connects to the exhaust chamber 6 or the external environment and has a larger cross-sectional area. This gradual expansion design causes the velocity of the oil fume airflow to gradually decrease during discharge, reducing dynamic pressure and increasing static pressure, thereby reducing airflow resistance and ensuring smooth flow. This helps to avoid the generation of turbulence and vortices, allowing the oil fume to pass more evenly through the rear filter layer a2, thus improving filtration efficiency.

[0025] In this embodiment, to further improve the filtration effect, the rear filter layer a2 is arranged at the outlet end of the exhaust duct 5. The outlet end, with its larger cross-sectional area, provides ample installation space, allowing the rear filter layer a2 to have a larger interception area. This arrangement fully utilizes the space of the exhaust duct 5, ensuring that the fumes come into full contact with the filter material at low speeds, extending the residence time and thus more effectively capturing fine particles and odor substances. The large area of ​​the rear filter layer a2 also disperses the airflow load, reducing the risk of localized blockage and maintaining long-term stable filtration performance.

[0026] In this embodiment, for ease of maintenance, multiple baffles 51 are provided on the end face of the exhaust duct 5. These baffles 51 form multiple slots on the end face. The rear filter layer a2 includes multiple independent filter plates a, each filter plate a being sized to match the slots and inserted into each slot. The arrangement of the baffles 51 and the formation of the slots make the disassembly, cleaning, or replacement of the filter plates a simple and quick.

[0027] In this embodiment, based on considerations of noise reduction and grease treatment, the fan assembly includes a fan housing 41, an impeller 42 disposed within the fan housing 41, and a driver 43 for driving the impeller 42. The fan housing 41 has a fan inlet 411 for guiding fumes into the flue 2 and a fan outlet 412 for discharging fumes into the exhaust duct 5. Multiple noise-reducing holes 413 are evenly distributed on its surface. These noise-reducing holes 413 have small diameters and are densely arranged to allow noise waves to pass through. The outer wall of the fan housing 41 is covered with a mesh-like porous structure layer 44, which is made of porous materials such as metal foam or fiber felt and is tightly adhered to the surface of the housing, installed by adhesive or mechanical fixing. When the impeller 42 rotates at high speed and generates noise, the sound waves enter the micropores of the mesh-like porous structure layer 44 through the noise-reducing holes 413, undergoing multiple reflections and absorptions within the micropores, converting sound energy into heat energy, thereby significantly reducing the noise level. Regarding grease treatment, as the fumes flow within the fan casing 41, some grease particles collide with the wall and seep out through the noise reduction holes 413, where they are then adsorbed and captured by the mesh porous structure layer 44. The adsorbed grease gradually accumulates under gravity and drips to the bottom of the smoke collection chamber 3, reducing grease buildup inside the fan casing 41 and preventing grease from affecting fan operation or producing odors. The noise reduction holes 413 and the mesh porous structure layer 44 provide the smoke collection chamber 3 with auxiliary filtration functionality. Combined with the initial filter layer a1 and the rear filter layer a2, this forms a multi-stage purification system, further improving the overall filtration effect.

[0028] In this embodiment, to prevent air leakage, a solid layer 45 covers the outside of the mesh porous structure layer 44. The solid layer 45 is made of a dense material such as plastic, metal plate, or rubber coating, and completely covers the outside of the mesh porous structure layer 44 through bonding, hot pressing, or mechanical fixing, forming a continuous and gapless sealing barrier. This covering structure blocks the leakage path of air or fumes, prevents potential air leakage problems caused by the porous structure, maintains the airflow stability and negative pressure environment inside the fan casing 41, and ensures the efficiency of fume treatment. The solid layer 45 also protects the mesh porous structure layer 44 from damage, contamination, or corrosion by external forces, extending its service life, while also making the appearance cleaner and easier to clean.

[0029] In this embodiment, considering grease discharge, an oil drain hole 414 is provided at the bottom of the fan housing 41. The oil drain hole 414 is usually located at the lowest point of the fan housing 41, and its diameter is optimized to allow accumulated grease to flow out smoothly without affecting the normal operation of the fan or causing air leakage. During the fume treatment process, some grease is thrown towards the inner wall of the fan housing 41 under the centrifugal force of the impeller 42 and gradually accumulates at the bottom. Through the oil drain hole 414, this accumulated grease can be automatically discharged to the bottom of the fume collection chamber 3 by gravity, thereby reducing grease residue inside the fan housing 41. This design avoids corrosion, noise, or efficiency reduction caused by long-term grease accumulation inside the fan, ensures the long-term stable operation of the fan, and simplifies the maintenance process.

[0030] In this embodiment, based on grease collection considerations, a drain pipe 32 is connected to the bottom of the smoke collection chamber 3 and the side of the air outlet chamber 6. One end of the drain pipe 32 is connected to the bottom of the smoke collection chamber 3, and the other end is connected to the side wall of the air outlet chamber 6. An oil cup 62 is provided inside the air outlet chamber 6. The drain pipe 32 guides the grease in the smoke collection chamber 3 into the oil cup 62 in the air outlet chamber 6, achieving centralized collection. This configuration effectively solves the problem of severe grease accumulation during the internal circulation absorption of fumes and the emission of clean air in integrated stoves, especially since the smoke collection chamber 3 is the main grease accumulation area, thus reducing the difficulty of cleaning and maintenance. At the same time, centralized grease collection also reduces the risk of grease clogging the air duct or affecting filtration efficiency.

[0031] In this embodiment, considering grease collection, the bottom of the smoke collection chamber 3 has a downwardly recessed oil collection groove 31. The oil collection groove 31 is integrally formed with the bottom of the smoke collection chamber 3 through stamping or molding processes. Its shape is rectangular or funnel-shaped, shallow in depth but large enough in area to effectively collect grease dripping from the fan housing 41 or discharged through the oil drain hole 414. The oil collection groove 31 is located at the lowest point of the bottom of the smoke collection chamber 3, facilitating natural grease flow and concentration, avoiding cleaning difficulties caused by large-area grease flow at the bottom. The drain pipe 32 connects to the bottom of the smoke collection chamber 3 at the center or lowest point of the oil collection groove 31, allowing grease to be more smoothly discharged to the air outlet chamber 6. The oil collection groove 31 improves the efficiency and thoroughness of grease collection, reduces residue, and extends the equipment maintenance cycle.

[0032] In this embodiment, based on the consideration of preliminary filtration, the smoke collection chamber 3 is equipped with a filter component for preliminary filtration of the inhaled oil fumes. It works in conjunction with the initial filter layer a1 of the smoke inlet duct 2 to capture some particulate matter and grease before the oil fumes enter the fan, thereby reducing the load on the fan components and improving the overall system durability and filtration efficiency.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
