Description

Technical Field

[0001] This invention relates to the field of cooktop technology, and in particular to a magnetically levitated cooktop and its method of use. Background Technology

[0002] Integrated smart cooktops are a type of modern kitchen appliance that combines multiple functions to improve kitchen space utilization and cooking efficiency. These cooktops typically include a gas stove, a range hood, and sometimes other functional modules such as a sterilizer, steamer, and oven. Currently, integrated smart cooktops on the market have achieved the integration of multiple functions, such as a gas stove and range hood, greatly improving kitchen space utilization and cooking efficiency.

[0003] Current integrated cooktops incorporate magnetic levitation technology, using a magnetic levitation motor to drive the fume extraction system. This uses a magnetic levitation bearing motor instead of traditional mechanical bearings to achieve frictionless operation, attracting younger consumers with its low noise and high energy efficiency (e.g., a 30% increase in heat load). However, when the fan is driven by the magnetic levitation motor, the extracted fumes have a long flow path, hindering rapid fumes separation. Over time, grease accumulates in the impeller and ductwork, reducing the fume extraction effect. Excessive grease buildup at the air inlet and ductwork poses a fire hazard if a cooking oil fire occurs. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a magnetically levitated stove and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetically levitated cooktop includes a body with a cooktop, and further includes:

[0007] The machine head is fixed to the top side of the machine body. The machine head has a flue for the flow of oil fumes and an oil filter is provided in the flue.

[0008] The smoke exhaust assembly includes a fan housing fixed inside the body, a magnetic levitation motor for driving the impeller inside the fan housing, an air intake pipe provided at the air intake end of the fan housing, and an exhaust pipe provided at the exhaust end of the fan housing.

[0009] The air intake pipe is connected to the oil filter at one end away from the fan casing, and the side wall of the machine body has a slot that matches the exhaust pipe.

[0010] Preferably, the oil filtration unit includes an oil filter shell fixed in the flue, an annular support fixed in the oil filter shell, and an oil filter cylinder disposed on the annular support. The oil filter cylinder adopts a cylindrical structure that is narrow at both ends and wide in the middle. An oil leakage groove is provided in the middle of the oil filter cylinder, and an oil receiving shell is connected to the bottom of the annular support.

[0011] Preferably, the top of the flue is fixed with a guide shell with an inclined inner wall, the bottom opening of the guide shell is connected to the air inlet of the oil filter shell, and the air outlet of the oil filter shell is connected to the air inlet pipe.

[0012] Preferably, a rotating rod is rotatably connected inside the air intake pipe, and a plurality of guide vanes are evenly arranged on the rotating rod in a circular pattern.

[0013] Preferably, a baffle is fixedly provided inside the flue, and the baffle and the inner wall of the flue together form a working cavity. The end of the rotating rod away from the air intake pipe passes through the baffle and extends into the working cavity. The rotating rod is provided with a transmission part for driving the oil filter cartridge to rotate inside the oil filter housing.

[0014] Preferably, the transmission unit includes a transmission rod rotatably connected to the partition plate, a first gear and a second gear disposed on the transmission rod, a drive gear disposed on the rotating rod and meshing with the first gear, and a driven gear fixed to the end of the oil filter cylinder and meshing with the second gear.

[0015] Preferably, a rotating rod is rotatably connected inside the oil filter cylinder, and an auxiliary oil removal component is provided on the rotating rod to move against the inner side wall of the oil filter cylinder. A secondary gear that meshes with the first gear is provided at one end of the rotating rod located outside the oil filter cylinder.

[0016] Preferably, the rotating rod is configured as two fixedly connected reciprocating screws, each reciprocating screw being threadedly connected to a sleeve. The auxiliary oil removal assembly includes an inclined rod parallel to the inner wall of the oil filter cylinder, a rotating plate fixedly connected to the inclined rod and rotatably connected to the inner wall of the oil filter cylinder, an elastic telescopic rod fixedly connected to the sleeve, a slider disposed on the movable end of the elastic telescopic rod and slidably connected to the inclined rod, a sliding rod slidably disposed on the movable end of the elastic telescopic rod, an elastic element disposed between the sliding rod and the movable end of the elastic telescopic rod, and a rubber block disposed at the end of the sliding rod and movably abutting against the inner wall of the oil filter cylinder. The inclined rod is fixedly provided with several protrusions, and the sliding rod is provided with an abutting block that movably abuts against the protrusions.

[0017] Preferably, the machine head includes a U-shaped plate fixed to the machine body, a smoke baffle plate disposed on the U-shaped plate, and a side plate snapped into the U-shaped plate. The side plate is rotatably connected to a closing plate at the oil inlet via a pin shaft, and a torsion spring for driving the closing plate to reset and rotate is disposed on the pin shaft.

[0018] This invention also discloses a method for using a magnetically levitated stove, comprising the following steps:

[0019] S1: Start the stove:

[0020] When you turn on the stove to cook, the magnetic levitation motor is activated at the same time. The magnetic levitation motor drives the impeller inside the fan housing to rotate at high speed, creating negative pressure to draw out the oil fumes.

[0021] S2: Fume Inhalation and Primary Filtration:

[0022] The fumes are drawn into the flue of the machine head, guided by the inclined inner wall of the guide shell, and concentrated into the oil filter shell. The fumes pass through the oil filter cylinder, and the oil molecules are intercepted on the inner wall of the oil filter cylinder. The flue gas passes through the oil filter cylinder and enters the air intake pipe.

[0023] S3: Oil droplet separation and collection:

[0024] The intercepted oil droplets gather on the inner wall of the oil filter cylinder, flow down through the central oil leakage groove to the annular support, and finally the oil droplets are collected in the oil receiving shell for storage.

[0025] S4: Airflow-driven self-cleaning system

[0026] When flue gas enters the intake pipe, it drives the guide vane to rotate, which in turn drives the rotating rod to rotate. Power is transmitted to the transmission rod through the drive gear. The second gear on the transmission rod meshes with the driven gear, causing the oil filter cartridge to rotate. Centrifugal force throws off residual oil droplets.

[0027] The first gear meshes with the secondary gear, driving the rotating rod to rotate, and the sleeve reciprocates along the axial direction of the rotating rod.

[0028] S5: Auxiliary oil removal component operation:

[0029] The sleeve drives the elastic telescopic rod to move, the slider slides along the inclined rod, the length of the elastic telescopic rod adapts to the inclination angle of the inner wall of the oil filter cartridge, the abutting block of the slider intermittently collides with the protrusion, the rubber block knocks the inner wall of the oil filter cartridge at high frequency, shaking off stubborn oil stains, accelerating the oil droplets to slide down, the knocking point changes dynamically, avoiding local wear;

[0030] S6: Flue gas emissions:

[0031] The clean flue gas is pressurized by the fan casing and discharged through the exhaust pipe and slots in the body.

[0032] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0033] 1. In this invention, by setting an oil filter cylinder in the flue, the structure of the oil filter cylinder (narrow at both ends and wide in the middle) combined with the rotational centrifugal force to throw oil, the oil droplet interception efficiency is significantly improved and the oil droplet removal rate is increased. Furthermore, by intermittently tapping the auxiliary oil removal component, oil droplet retention is prevented, thus solving the problem of long oil fume paths in traditional integrated stoves, oil molecules depositing in the impeller / duct, which can easily cause fires when exposed to open flames.

[0034] 2. In this invention, turbulence is suppressed by rotating the guide vanes, cutting large-scale eddies into small-scale vortices, reducing turbulence intensity, making the airflow distribution more uniform, reducing noise generated in local high-speed areas, and making the flue gas flow evenly. The uniform airflow distribution reduces the fan load and indirectly reduces noise. The combination of the low noise of magnetic levitation and the airflow optimization of the guide vanes achieves ultra-quiet operation of the integrated stove.

[0035] 3. In this invention, the energy of the flue gas flow is used to drive the guide vane to rotate, which in turn drives the oil filter cartridge to rotate and the auxiliary oil removal component to work. No additional power is required, which makes the integrated stove energy-saving and efficient.

[0036] 4. In this invention, by intermittently striking the rubber block of the auxiliary oil removal component, the rubber block strikes different positions on the inner wall of the oil filter cylinder, avoiding striking the same position on the oil filter cylinder at all times, thus preventing local wear while accelerating the oil removal process on the inner wall of the oil filter cylinder.

Detailed Implementation

[0049] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0050] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, this embodiment proposes a magnetically levitated stove, including a body 1 with a stovetop 101, and also including a head unit 2 and a smoke exhaust assembly. The head unit 2 is fixed to the top side of the body 1, and a flue 201 for oil fume flow is opened inside the head unit 2. An oil filter is provided inside the flue 201. The smoke exhaust assembly includes a fan housing 3 fixed inside the body 1, a magnetically levitated motor 303 for driving the impeller inside the fan housing 3, an air intake pipe 301 provided at the air intake end of the fan housing 3, and an exhaust pipe 302 provided at the exhaust end of the fan housing 3. The end of the air intake pipe 301 away from the fan housing 3 is connected to the oil filter, and a slot 102 that cooperates with the exhaust pipe 302 is opened on the side wall of the body 1.

[0052] Specifically, when cooking is initiated on the stovetop 101, the magnetic levitation motor 303 is simultaneously activated. The magnetic levitation motor 303 drives the impeller inside the fan housing 3 to rotate at high speed, creating negative pressure to draw in cooking fumes. The magnetic levitation motor 303 is a current technology, a special motor that uses magnetic levitation technology to achieve contactless levitation and drive of the rotor. By replacing traditional mechanical bearings with electromagnetic force, friction loss and noise are significantly reduced. The magnetic levitation motor 303 drives the impeller inside the fan housing 3, causing the air intake pipe 301 of the fan housing 3 to generate suction. The flue 201 draws in the cooking fumes generated on the stovetop 101. The drawn-in fumes are filtered by the oil filter, reducing the oil content of the fumes entering the exhaust assembly. The fumes are then discharged from the exhaust pipe 302. This solves the problem of long fume paths and oil molecule deposition in the impeller / duct of traditional integrated stoves, which can easily cause fires when exposed to open flames.

[0053] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in a preferred embodiment, based on the above method, the oil filter section further includes an oil filter shell 4 fixed in the flue 201, an annular support 401 fixed in the oil filter shell 4, and an oil filter cylinder 5 mounted on the annular support 401. A speed-limiting bearing is installed between the oil filter cylinder 5 and the annular support 401 to control the rotation speed, ensure its rotational stability, and avoid uneven rotation due to fluctuations in flue gas flow. The oil filter cylinder 5 adopts a cylindrical structure that is narrow at both ends and wide in the middle. An oil leakage groove 501 is opened in the middle of the oil filter cylinder 5. The bottom of the annular support 401 is connected to an oil receiving shell 402. The oil filter shell 4 is fixed in the flue 201. As the core cavity for oil droplet separation, the material must be heat-resistant and corrosion-resistant. The oil filter cylinder 5 adopts a cylindrical structure design that is narrow at both ends and wide in the middle to increase the contact area of ​​oil fumes. The width of the oil drain groove 501 in the middle facilitates the collection and downward flow of oil droplets. The oil receiving shell 402 is connected to the bottom of the annular support 401 and adopts a detachable design to facilitate regular cleaning of accumulated oil. After the oil fumes enter the flue 201, they are guided by the airflow and impact the wide area in the middle of the oil filter cylinder 5. The oil molecules are intercepted by the inner wall of the oil filter cylinder 5 and converge into droplets under the action of centrifugal force or gravity. The droplets slide down through the oil drain groove 501 and flow into the oil receiving shell 402 along the opening of the annular support 401, thus achieving oil fume separation.

[0054] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, a guide shell 6 with an inclined inner wall is fixed to the top of the flue 201. The bottom opening of the guide shell 6 is connected to the air inlet of the oil filter shell 4, and the air outlet of the oil filter shell 4 is connected to the air inlet pipe 301. The inclined inner wall design of the guide shell 6 ensures that the oil fumes are guided and concentrated. The bottom opening of the guide shell 6 is precisely connected to the air inlet of the oil filter shell 4. The air outlet of the oil filter shell 4 is connected to the air inlet pipe 301 through a flange to form a sealed airflow channel. The inclined inner wall of the guide shell 6 can accelerate the flow of oil fumes and reduce turbulence. The oil filter shell 4 has a built-in annular support 401 and an oil filter cylinder 5 to achieve oil droplet interception and collection. The oil fumes are intercepted in the oil filter cylinder 5. After purification, the flue gas enters the air inlet pipe 301 from the air outlet of the oil filter shell 4. The clean flue gas enters the fan shell 3 through the air inlet pipe 301 and is finally discharged through the exhaust pipe 302.

[0055] Reference Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a rotating rod 7 is rotatably connected inside the air intake pipe 301, and a plurality of guide vanes 701 are evenly arranged on the rotating rod 7 in a circular pattern. The rotation of the guide vanes 701 suppresses turbulence, cuts large-scale eddies into small-scale vortices, reduces turbulence intensity, makes the airflow distribution more uniform, reduces noise generated in local high-speed areas, and makes the flue gas flow evenly and dispersed. The uniform airflow distribution reduces the fan load and indirectly reduces noise. The combination of the low noise of magnetic levitation and the airflow optimization of the guide vanes 701 achieves ultra-quiet operation of the integrated stove. It should be noted that a guide block or guide port should be provided at the port of the air intake pipe 301. This is existing technology and will not be described in detail here. It is used to guide the flowing flue gas to the guide vanes 701 on the side of the rotating rod 7, so that the guide vanes 701 rotate.

[0056] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a partition 3011 is further fixed inside the flue 201. The partition 3011 and the inner wall of the flue 201 form a working cavity. The end of the rotating rod 7 away from the air intake pipe 301 passes through the partition 3011 and extends into the working cavity. The rotating rod 7 is provided with a transmission part for driving the oil filter cartridge 5 to rotate inside the oil filter shell 4.

[0057] Furthermore, the transmission unit includes a transmission rod 8 rotatably connected to the partition plate 3011, a first gear 801 and a second gear 802 disposed on the transmission rod 8, a drive gear 702 disposed on the rotating rod 7 and meshing with the first gear 801, and a driven gear 502 fixed to the end of the oil filter cylinder 5 and meshing with the second gear 802.

[0058] Specifically, the partition 3011 and the inner wall of the flue 201 form a sealed working chamber, isolating the oil fumes from the mechanical transmission components and preventing oil stains from corroding. The rotating rod 7 extends through the partition 3011 into the working chamber and achieves dynamic sealing through the sealed bearing. The flue gas pushes the guide vane 701 inside the air intake pipe 301, and the rotating rod 7 rotates and drives the gear 702 to mesh with the first gear 801. The transmission rod 8 meshes with the driven gear 502 through the second gear 802, causing the oil filter cartridge 5 to rotate. The centrifugal force throws the oil droplets onto the oil receiving shell 402, shortening the residence time of the oil droplets on the inner wall of the oil filter cartridge 5 and preventing the oil droplets from hindering the rapid passage of the flue gas. The gear set converts the kinetic energy of the high-speed flue gas into the low-speed rotation of the oil filter cartridge 5, realizing the efficient conversion of "airflow-mechanical" energy.

[0059] Reference Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, a rotating rod 9 is rotatably connected inside the oil filter cylinder 5. An auxiliary oil removal component is provided on the rotating rod 9 to move against the inner side wall of the oil filter cylinder 5. A secondary gear 908 that meshes with the first gear 801 is provided at one end of the rotating rod 9 located outside the oil filter cylinder 5.

[0060] Furthermore, the rotating rod 9 is configured as two reciprocating screws fixedly connected together, and each reciprocating screw is threadedly connected to a sleeve 901. The auxiliary oil removal assembly includes an inclined rod 902 arranged parallel to the inner wall of the oil filter cylinder 5, a rotating plate 903 fixedly connected to the inclined rod 902 and rotatably connected to the inner wall of the oil filter cylinder 5, an elastic telescopic rod 904 fixedly connected to the sleeve 901, a slider 9041 arranged on the movable end of the elastic telescopic rod 904 and slidably connected to the inclined rod 902, a sliding rod 905 slidably arranged on the movable end of the elastic telescopic rod 904, an elastic element 906 arranged between the sliding rod 905 and the movable end of the elastic telescopic rod 904, and a rubber block 907 arranged at the end of the sliding rod 905 and movably abutting against the inner wall of the oil filter cylinder 5. Several protrusions 9021 are fixedly provided on the inclined rod 902, and an abutting block 9051 that movably abuts against the protrusions 9021 is provided on the sliding rod 905.

[0061] Specifically, the rotating rod 9 adopts a two-stage reciprocating screw structure, which meshes with the first gear 801 through the auxiliary gear 908 to achieve rotational transmission. The sleeve 901 is threadedly connected to the reciprocating screw, driving the elastic telescopic rod 904 to move axially back and forth. The movable end of the elastic telescopic rod 904 freely extends and retracts with the inclination of the tilting rod 902 under the action of the slider 9041, ensuring that the movable end of the elastic telescopic rod 904 always maintains the same position with the inclined inner wall of the oil filter cylinder 5. This avoids excessive or insufficient impact force of the rubber block 907 on the inner wall of the oil filter cylinder 5 as the sleeve 901 moves, which would affect the downward speed of the oil droplets. As the sleeve 901 moves back and forth along the rotating rod 9, the abutment block 9051 on the slider 905 and the tilting rod... The intermittent contact of the protrusion 9021 on 902 causes the rubber block 907 at the end of the slide rod 905 to intermittently contact and collide with the inner wall of the rotating oil filter cylinder 5, accelerating the speed at which oil droplets slide down the inner wall of the oil filter cylinder 5, ensuring the speed of flue gas passage within the oil filter cylinder 5. Furthermore, the rubber block 907 can contact different positions on the inner wall of the oil filter cylinder 5, avoiding constant impact on the same position, which would cause rapid damage to that location. A wear-resistant coating is applied to the surface of the rubber block 907 to improve its service life. It should be noted that protective tubes should be provided on both sides of the sleeve 901, which are slidably connected to the rotating rod 9, to prevent oil contaminants from entering the track groove of the reciprocating screw and affecting the transmission displacement of the sleeve 901 on the reciprocating screw.

[0062] Reference Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the head unit 2 further includes a U-shaped plate 202 fixedly connected to the body 1, a smoke baffle 203 disposed on the U-shaped plate 202, and a side plate 204 snapped onto the U-shaped plate 202. The side plate 204 is rotatably connected to a closing plate 205 at the oil receiving shell 402 via a pin. A torsion spring is provided on the pin for driving the closing plate 205 to reset and rotate. The side plate 204 is quickly disassembled and assembled with the U-shaped plate 202 via a snap-fit ​​structure. The closing plate 205 is hinged to the end of the side plate 204 via a pin. The pin has a built-in stainless steel torsion spring for automatic reset. The closing plate 205 covers the opening of the oil receiving shell 402. Under normal conditions, it is kept sealed by the torsion spring. When cleaning is required, it is manually lifted and automatically closed after being released. A rubber sealing strip is added to the edge of the closing plate 205 to ensure its sealing effect. The smoke baffle 203 intercepts the rising oil fumes and guides them to the oil filter flue 201 for oil filtration and discharge.

[0063] This invention also discloses a method for using a magnetically levitated stove, comprising the following steps:

[0064] S1: Start the stove:

[0065] Cooking begins with the stovetop 101, and simultaneously the magnetic levitation motor 303 is activated. The magnetic levitation motor 303 drives the impeller inside the fan housing 3 to rotate at high speed, creating negative pressure to draw out the fumes.

[0066] S2: Fume Inhalation and Primary Filtration:

[0067] The fumes are drawn into the flue 201 of the head 2, guided by the inclined inner wall of the guide shell 6, and concentrated into the oil filter shell 4. The fumes pass through the oil filter cylinder 5, and the oil molecules are intercepted on the inner wall of the oil filter cylinder 5. The fumes pass through the oil filter cylinder 5 and enter the air intake pipe 301.

[0068] S3: Oil droplet separation and collection:

[0069] The intercepted oil droplets gather on the inner wall of the oil filter cylinder 5, flow down through the middle oil leakage groove 501 to the annular support 401, and finally the oil droplets are stored in the oil receiving shell 402.

[0070] S4: Airflow-driven self-cleaning system

[0071] When the flue gas enters the intake pipe 301, it drives the guide vane 701 to rotate. The guide vane 701 drives the rotating rod 7 to rotate. The power is transmitted to the transmission rod 8 through the drive gear 702. The second gear 802 on the transmission rod 8 meshes with the driven gear 502, causing the oil filter cartridge 5 to rotate. The centrifugal force throws off the residual oil droplets.

[0072] The first gear 801 meshes with the secondary gear 908, driving the rotating rod 9 to rotate, and the sleeve 901 reciprocates along the axial direction of the rotating rod 9.

[0073] S5: Auxiliary oil removal component operation:

[0074] The sleeve 901 drives the elastic telescopic rod 904 to move, the slider 9041 slides along the inclined rod 902, the length of the elastic telescopic rod 904 adapts to the inclination angle of the inner wall of the oil filter cylinder 5, the abutting block 9051 of the slide rod 905 collides intermittently with the protrusion 9021, the rubber block 907 strikes the inner wall of the oil filter cylinder 5 at high frequency, shaking off stubborn oil stains, accelerating the oil droplets to slide down, the striking point changes dynamically, and avoids local wear;

[0075] S6: Flue gas emissions:

[0076] The clean flue gas is pressurized by the fan casing 3 and discharged through the exhaust pipe 302 and the slot 102 of the body 1.

[0077] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

3. A method of using a magnetically levitated stove according to claim 2, characterized in that, Includes the following steps: S1: Start the stove: When you turn on the stove to cook, the magnetic levitation motor is activated at the same time. The magnetic levitation motor drives the impeller inside the fan housing to rotate at high speed, creating negative pressure to draw out the oil fumes. S2: Fume Inhalation and Primary Filtration: The fumes are drawn into the flue of the machine head, guided by the inclined inner wall of the guide shell, and concentrated into the oil filter shell. The fumes pass through the oil filter cylinder, where oil molecules are intercepted on the inner wall of the oil filter cylinder, and the flue gas passes through the oil filter cylinder into the air intake pipe. S3: Oil droplet separation and collection: The intercepted oil droplets gather on the inner wall of the oil filter cylinder, flow down through the central oil leakage groove to the annular support, and finally the oil droplets flow into the oil receiving shell for storage; S4: Airflow-driven self-cleaning system When flue gas enters the intake pipe, it drives the guide vane to rotate, which in turn drives the rotating rod to rotate. Power is transmitted to the transmission rod through the drive gear. The second gear on the transmission rod meshes with the driven gear, causing the oil filter cartridge to rotate. Centrifugal force throws off residual oil droplets. The first gear meshes with the secondary gear, driving the rotating rod to rotate, and the sleeve reciprocates along the axial direction of the rotating rod. S5: Auxiliary oil removal component operation: The sleeve drives the elastic telescopic rod to move, the slider slides along the inclined rod, the length of the elastic telescopic rod adapts to the inclination angle of the inner wall of the oil filter cylinder, the abutting block of the slider intermittently collides with the protrusion, the rubber block knocks the inner wall of the oil filter cylinder at high frequency, shaking off stubborn oil stains, accelerating the oil droplets to slide down, the knocking point changes dynamically, avoiding local wear; S6: Flue gas emissions: The clean flue gas is pressurized by the fan casing and discharged through the exhaust pipe and slots in the body.
