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 available in models where the smoke extraction, filtration, and exhaust functions are integrated within the cooktop. This allows for in-situ purification of cooking fumes and the recirculation of clean air, avoiding the limitations of external exhaust range hoods that require ductwork extending outdoors. However, this internal circulation mode has several drawbacks: because cooking fumes are forced through multiple filters within the cooktop, grease inevitably separates and accumulates in various cavities and components, particularly in the smoke collection chamber and its internal fan assembly—the core area for fume treatment. Over time, this significant grease buildup not only breeds bacteria and produces odors, affecting kitchen hygiene, but can also clog ducts, increase fan load, reduce filtration efficiency, and even corrode internal components, ultimately leading to performance degradation, shortened lifespan, and increased maintenance costs. Utility Model Content
[0003] The purpose of this invention is to provide an integrated stove that enables centralized collection and cleaning of grease inside the stove, thereby solving the problem of severe grease accumulation in the smoke collection chamber under internal circulation mode.
[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 arranged in sequence inside the stove. The smoke inlet duct has an opening on the stove surface and a smoke collection hood for drawing in cooking fumes at the opening. The air outlet chamber has an air outlet on the stove surface for discharging clean air.
[0006] The bottom of the smoke collection chamber and the side of the air outlet chamber are connected to a drain pipe. The drain pipe is used to discharge the grease in the smoke collection chamber to the air outlet chamber. An oil cup is installed in the air outlet chamber to collect the grease discharged into the air outlet chamber by the drain pipe.
[0007] As a further improvement of this utility model, the stove is provided with a detachable cover plate corresponding to the air outlet, and the air outlet is formed on the cover plate.
[0008] As a further improvement of this utility model, the air outlet cavity is provided with a hanging part near the air outlet, and the oil cup includes a cup body for collecting grease, a hook hanging on the hanging part, and a connecting part connecting the cup body and the hook.
[0009] As a further improvement of this utility model, the mounting part is set on the side wall of the air outlet cavity away from the exhaust duct, the connecting part is connected to the side of the cup body away from the exhaust duct, and the connecting part is set close to the side wall of the air outlet cavity away from the exhaust duct.
[0010] As a further improvement of this utility model, the two ends of the sewage pipe are detachably connected to the bottom of the smoke collection chamber and the side of the air outlet chamber, respectively.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] As a further improvement of this utility model, the inlet flue is provided with a primary filter layer, and the exhaust flue is provided with a rear filter layer.
[0016] The beneficial effects of this utility model are:
[0017] By installing a drain pipe and an oil cup in the air outlet cavity, the problem of severe grease accumulation during the internal circulation absorption of fumes and the emission of clean air in integrated stoves can be effectively solved. In particular, the fume collection cavity 3, as the main area for grease accumulation, has its grease discharged into the oil cup through the drain pipe, which avoids the spread and residue of grease on internal components, thereby reducing the difficulty of cleaning and maintenance, improving the hygiene level of the equipment and its long-term reliability. At the same time, centralized grease collection also reduces the risk of grease clogging the air duct or affecting the filtration efficiency. Attached Figure Description
[0018] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings to help understand the purpose and advantages of this utility model, wherein:
[0019] Figure 1 This is a structural diagram of an integrated stove;
[0020] Figure 2 This is a cross-sectional view of an integrated stove. Detailed Implementation
[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, see reference. Figure 1 and Figure 2 The integrated stove mainly includes an inlet duct 2, a smoke collection hood 1, an exhaust duct 5, and an air outlet chamber 6, all located inside the cooktop. These components are connected sequentially to form a complete internal circulation oil fume treatment path. The inlet duct 2 has an opening on the cooktop surface, where a smoke collection hood 1 is installed to draw in the oil 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 forms an air outlet 61 on the cooktop surface to discharge filtered clean air. The bottom of the smoke collection chamber 3 and the side of the air outlet chamber 6 are connected by a drain pipe 32. The drain pipe 32 guides the grease accumulated in the smoke collection chamber 3 to the air outlet chamber 6. An oil cup 62 is installed inside the air outlet chamber 6 to collect the grease discharged from the drain pipe 32. In actual operation, fumes enter the fume collection chamber 3 from the inlet duct 2, are driven by the fan assembly to the exhaust duct 5, and are purified by the filter components. Finally, clean air is discharged from the outlet 61. Grease gradually accumulates in the fume collection chamber 3 due to gravity or airflow, and automatically flows into the grease cup 62 in the exhaust chamber 6 through the drain pipe 32 for centralized collection. By setting up the drain pipe 32 and the grease cup 62 in the exhaust chamber 6, the problem of severe grease accumulation during the internal circulation absorption of fumes and the discharge of clean air in integrated stoves can be effectively solved. In particular, the fume collection chamber 3 is the main accumulation area for grease. The grease is centrally discharged into the grease cup 62 through the drain pipe 32, avoiding the spread and residue of grease on internal components, thereby reducing the difficulty of cleaning and maintenance, improving the hygiene level of the equipment and the reliability of long-term use. At the same time, centralized grease collection also reduces the risk of grease clogging the air duct or affecting the filtration efficiency.
[0024] In this embodiment, for ease of cleaning and maintenance, a removable cover plate 63 is provided on the part of the stove corresponding to the air outlet 6, and the air outlet 61 is formed on the cover plate 63. The cover plate 63 can be connected to the stove surface by means of clips, screws, or magnetic adsorption, allowing users to easily remove and install it in daily use. When it is necessary to clean the oil cup 62, the user only needs to remove the cover plate 63 to easily remove the oil cup 62 for cleaning or replacement. This removable design not only simplifies the maintenance process but also avoids cleaning difficulties caused by complex fixed structures.
[0025] In this embodiment, to further improve the ease of installation and retrieval of the oil cup 62, the air outlet cavity 6 is provided with a hanging part 64 near the air outlet 61. The oil cup 62 includes a cup body 621 for collecting grease, a hook 622 that hangs on the hanging part 64, and a connecting part 623 that connects the cup body 621 and the hook 622. The hanging part 64 is located on the inner wall of the air outlet cavity 6, and the hook 622 cooperates with the hanging part 64 to allow the oil cup 62 to be stably suspended inside the air outlet cavity 6. The connecting part 623 ensures that the cup body 621 remains balanced when suspended. This arrangement allows the user to remove the cover plate 63 and directly lift or hang back the oil cup 622 using the hook 622, making the operation simple and quick. The oil cup 62 can be suspended to avoid contact with the bottom wall of the air outlet cavity 6, reducing contamination; or it can be placed on the bottom wall as needed to increase stability.
[0026] In this embodiment, to avoid interfering with the airflow within the air outlet cavity 6, the mounting portion 64 is disposed on the side wall of the air outlet cavity 6 away from the exhaust duct 5. The connecting portion 623 is connected to the side of the cup body 621 away from the exhaust duct 5, and the connecting portion 623 is disposed close to the side wall of the air outlet cavity 6 away from the exhaust duct 5. The positional arrangement of the mounting portion 64 and the connecting portion 623 causes the overall position of the oil cup 62 to be offset towards one side of the air outlet cavity 6, away from the exhaust duct 5 outlet, thereby minimizing obstruction to the clean airflow path and avoiding noise problems caused by component interference.
[0027] In this embodiment, to facilitate cleaning of the drain pipe 32, both ends of the drain pipe 32 are detachably connected to the bottom of the smoke collection chamber 3 and the side of the air outlet chamber 6, respectively. The detachable connection can be achieved using threaded joints, quick-connect clamps, or flange connections, ensuring a secure connection and easy disassembly. During deep cleaning, the user can remove the drain pipe 32 from the smoke collection chamber 3 and the air outlet chamber 6, and thoroughly rinse the accumulated grease residue inside the pipe with clean water or detergent to prevent blockage or corrosion. This solves the problem of hardened grease on the inner wall of the drain pipe 32 after long-term use, extending the service life of the pipeline. Simultaneously, the detachable connection facilitates installation and replacement, reducing maintenance costs.
[0028] In this embodiment, 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 oil fumes into the smoke inlet duct 2 and a fan exhaust outlet 412 for discharging oil fumes into the exhaust duct 5. The fan housing 41 has multiple noise reduction holes 413 arranged on it, and its outer wall is covered with a mesh porous structure layer 44. The noise reduction holes 413 are evenly distributed on the surface of the fan housing 41, allowing noise waves to pass through; the mesh porous structure layer 44 is made of porous materials such as metal foam or fiber felt and is tightly wrapped around the outside of the housing. In terms of noise reduction, when the impeller 42 rotates at high speed and generates noise, the sound waves enter the micropores of the mesh porous structure layer 44 through the noise reduction hole 413, and undergo multiple reflections and absorptions in the micropores, which significantly reduces the noise. In terms of grease treatment, when the grease flows inside the fan casing 41, some grease particles will collide with the wall and seep out through the noise reduction hole 413, and then be adsorbed and captured by the mesh porous structure layer 44. The adsorbed grease drips to the bottom of the smoke collection chamber 3 under the action of gravity, thereby reducing the accumulation of grease inside the fan casing 41 and preventing grease from affecting the operation of the fan or producing odors.
[0029] In this embodiment, to further improve sealing and prevent air leakage, a solid layer 45 is wrapped around the mesh porous structure layer 44. The solid layer 45, made of a dense material such as plastic, metal plate, or rubber coating, completely covers the outer side of the mesh porous structure layer 44, forming a sealing barrier. The solid layer 45 is bonded to the mesh porous structure layer 44 by adhesive bonding, hot pressing, or mechanical fixing, ensuring no gaps exist and thus blocking the leakage path of air or fumes. This arrangement prevents potential air leakage problems caused by the porous structure, maintains the airflow stability inside the fan housing 41, and ensures the efficiency of fume treatment. At the same time, the solid layer 45 also protects the mesh porous structure layer 44, preventing it from being damaged or contaminated by external forces and extending its service life.
[0030] In this embodiment, considering the grease treatment inside the fan housing 41, an oil drain hole 414 is provided at the bottom of the fan housing 41 to drain the grease inside the fan housing 41 to the bottom of the smoke collection chamber 3. The oil drain hole 414 is usually located at the lowest point of the fan housing 41, and its diameter is large enough to allow the 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 drained to the bottom of the smoke collection chamber 3 by gravity, thereby reducing the grease residue inside the fan housing 41. The setting of the oil drain hole 414 avoids the corrosion, noise or efficiency reduction problems caused by long-term accumulation of grease inside the fan, ensuring the long-term stable operation of the fan.
[0031] In this embodiment, to optimize grease collection efficiency, the bottom of the smoke collection chamber 3 has a downwardly recessed oil collection groove 31 for collecting grease dripping to the bottom of the smoke collection chamber 3, and the drain pipe 32 is connected to the bottom of the smoke collection chamber 3 at a position corresponding to the oil collection groove 31. The oil collection groove 31 is integrally formed with the bottom of the smoke collection chamber 3 by stamping or molding, and its shape is designed as rectangular or funnel-shaped to ensure effective collection of 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, which facilitates the natural flow and concentration of grease, avoiding cleaning difficulties caused by large-area grease flow at the bottom. This design improves the efficiency and thoroughness of grease collection, reduces residue, and allows the drain pipe 32 to more smoothly discharge grease into the air outlet chamber 6.
[0032] In this embodiment, to improve the fume filtration effect, the inlet duct 2 is equipped with a primary filter layer a1, and the exhaust duct 5 is equipped with a secondary filter layer a2. Both the primary filter layer a1 and the secondary filter layer a2 are made of porous filter materials such as metal mesh or activated carbon fiber, capable of capturing larger particles and grease in the fumes. The primary filter layer a1 is located at the inlet of the inlet duct 2, performing preliminary filtration of the fumes to remove large particulate impurities; the secondary filter layer a2 performs deep filtration of the fumes processed by the fan in the exhaust duct 5, ensuring the cleanliness of the exhaust air. This dual filtration system significantly improves the fume purification efficiency, reduces the emission of harmful substances, and protects internal components from contamination.
[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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
