Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and specifically to a silent integrated stove. Background Art

[0002] As a kitchen appliance integrating functions such as a range hood, a gas stove, and a disinfection cabinet, the core advantages of an integrated stove lie in saving space and efficient smoke exhaust. However, there are still significant defects in the actual application of existing integrated stoves: Insufficient noise control: Traditional integrated stoves rely on sound-absorbing cotton or sound-insulating layers to passively absorb noise, but the operation of the fan and the violent collision of the air flow with the fixed air duct wall surface still generate high-frequency noise. Especially when users use the stove on one side for a long time, the unoptimized air flow path leads to increased turbulence and further increased noise; Low exhaust efficiency and flexibility: The existing exhaust structure is a fixed design and cannot adjust the direction of the smoke suction port according to the use requirements of the stove on one side, resulting in ineffective suction on the non-working side, increased energy consumption, and an increased risk of oil fume escaping.

[0003] In view of the above problems, there is an urgent need for an integrated stove design scheme that can be improved synergistically from multiple dimensions such as optimizing the air flow path, dynamic adjustment, and mechanical noise reduction to achieve the unity of noise reduction at the source and precise suction. Summary of the Invention

[0004] The purpose of the present invention is to provide a silent integrated stove to solve the problems that the existing integrated stove generates relatively large noise during use, is not convenient to adjust the corresponding orientation of the oil fume extraction structure according to the actual use situation, and is not convenient to efficiently utilize the oil fume extraction structure.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A silent integrated stove, comprising: An integrated stove body, in which a smoke exhaust component is fixedly installed inside the integrated stove body; A smoking box, which is fixedly installed on the back of the integrated stove body. The smoke exhaust component communicates with the inner cavity of the smoking box, and a smoking window is provided on the front of the smoking box; A noise reduction component, in which a noise reduction component with a smoking port opened on the outer circle is rotatably installed inside the smoking box. The center of the noise reduction component is rotatably connected to a support frame fixedly connected to the smoking box. A servo motor with an output end connected to the center of the noise reduction component is fixedly installed inside the support frame. A ventilation window communicating the smoke exhaust component and the noise reduction component is opened inside the smoking box; A limiting frame, which is fixedly installed inside the smoking box. An accommodating cavity for the noise reduction component to rotate is provided inside the limiting frame, and the upper half structure of the limiting frame is used to guide the smoking orientation of the smoking port at the top of the noise reduction component.

[0006] This technical solution drives the noise reduction component to rotate through a servo motor, enabling the smoke suction port to adjust its orientation according to the usage requirements of a single-side cooking appliance. It breaks through the limitations of the traditional fixed exhaust mode of integrated stoves, realizes the dynamic matching of the exhaust direction and the position where oil fumes are generated, thereby significantly improving the capture efficiency of oil fumes during single-side use, reducing the loss of ineffective air volume, and achieving the purpose of energy conservation. The upper half structure of the limit frame forms a directional flow guiding channel through physical constraints, concentrating the wind force at the smoke suction port on the top of the noise reduction component and guiding it to the target area, effectively suppressing the lateral dissipation of the air flow, making the negative pressure area more accurately cover the working range of the cooking appliance, and improving the effective suction force under the same fan power, taking into account both energy efficiency and exhaust effect. The noise reduction component is integrated into the interior of the smoke suction box in a rotatable manner, and the compact layout of the motor and the noise reduction module is realized through the support frame. The noise reduction function and the direction adjustment function are simultaneously achieved within a limited space, avoiding the problem of bulky volume caused by external noise reduction devices, which meets the core requirement of integrated stoves for saving space. The rotational cooperation between the noise reduction component and the limit frame forms a dynamic sealing interface. When the smoke suction port turns to one side, the non-working side forms a physical isolation through the fitting of the outer wall of the component and the frame, blocking the path of oil fume backflow. Compared with the static sealing structure, this solution can reduce the problem of kitchen odor while ensuring the flexibility of adjustment.

[0007] The smoke suction ports opened on the outer ring of the noise reduction component are rotated by the drive of a servo motor, and the smoke suction direction can be adjusted according to the usage position of the cooking appliance, which can keep the air flow path in the shortest and most direct state all the time, avoiding the turbulent noise generated by the air flow turning in the traditional fixed air duct. The upper half of the limit frame forms a directional flow guiding channel through a physical structure, forcing the air flow to flow along the preset path, eliminating the disordered collision between the air flow and the inner wall of the air duct, and reducing the broadband noise (especially in the medium and high frequency bands) caused by the air flow scattering.

[0008] Preferably, it further includes a cleaning component. The cleaning component includes a washing component installed inside the noise reduction component. The outer ring of the washing component fits the inner cavity surface of the noise reduction component, and a pumping component for delivering detergent to the washing component is fixedly installed inside the integrated stove body and the smoke suction box.

A first retaining ring, a second retaining ring, and a third retaining ring are sequentially welded between the front cover and the rear cover from the inner ring to the outer ring. A support tube rotatably connected to the outer ring of the support frame is welded at the center of the front cover and the rear cover, and the center of the support tube is fixedly connected to the output end of the servo motor; The ventilation window penetrates the front cover and is located between the first retaining ring and the support tube. Smoke suction ports are opened at the top of the first retaining ring and the third retaining ring, and a smoke suction port is opened at the bottom of the second retaining ring. Multiple communication grooves for accommodating the pumping component are opened inside the front cover.

[0010] Preferably, the limiting frame includes two groups of symmetric arc plates with the inner circles close to the outer circles of the third retaining rings. The tops of the two groups of arc plates are both connected by inclined plates to side baffles installed at the sides of the smoking window. A partition plate with the bottom end close to the top end of the noise reduction component is provided at the center of the smoking window. The arc plates, side baffles and partition plate are all welded to the inner wall of the smoking box.

[0011] Preferably, two groups of symmetric auxiliary rollers are rotatably installed inside the smoking box. The two groups of auxiliary rollers are respectively installed at the bottom ends of the two groups of arc plates, and both groups of auxiliary rollers are in contact with the outer circle of the third retaining ring.

[0012] Preferably, a ventilation pipe is connected between the smoke exhaust component and the ventilation window. A vertical rod supporting the pumping component is welded inside the inner circle of the ventilation pipe.

[0013] Preferably, a net is installed inside the ventilation window. A communication groove for the pumping component to penetrate is left between the inner circle of the net and the front cover.

[0014] Preferably, the pumping component includes a water pump fixedly installed inside the integrated stove body. The input end of the water pump is communicated with a water suction pipe extending outside the integrated stove body. The output end of the water pump is communicated with a water delivery pipe passing through the ventilation pipe and extending outside the integrated stove body. The water delivery pipe is communicated with the washing component through a plurality of horizontal pipes passing through the communication groove.

[0015] Preferably, the washing component includes a plurality of rectangular frames installed between two adjacent retaining rings or between the first retaining ring and the support pipe. The inner cavity of the rectangular frame is communicated with the end of the horizontal pipe. A brush is provided on the outer circle of the rectangular frame to fit the surfaces of the cover, retaining ring and support pipe.

[0016] Preferably, an inclined guide plate is installed at the bottom of the inner cavity of the smoking box. One side of the smoking box is communicated with a sewage pipe located at the bottom end of the inclined guide plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this technical solution, the noise reduction component is driven by a servo motor to rotate, so that the smoking port can be adjusted according to the use requirements of the single-side stove, breaking through the limitation of the traditional fixed air extraction mode of the integrated stove, realizing the dynamic matching of the air extraction direction and the position where the oil fume is generated, thereby significantly improving the capture efficiency of the oil fume during single-side use, reducing the loss of ineffective air volume, achieving the purpose of energy conservation, avoiding the turbulent noise generated by the airflow turning in the traditional fixed air duct, and actively suppressing the generation of noise through the optimization of the airflow path.

[0018] 2. In this technical solution, structures such as the first retaining ring, the second retaining ring, the third retaining ring, and the support pipe are arranged on the necessary route for oil fume extraction. The first retaining ring, the second retaining ring, and the third retaining ring are provided with staggered smoking ports. Multiple groups of retaining rings can achieve efficient noise reduction during the operation of the oil fume extraction structure, thereby improving the actual comfort of users of the integrated stove. Moreover, multiple groups of nested arc-shaped retaining rings can effectively collect the oil stains in the oil fume, reduce the oil stains directly adhering to the fan impeller, thereby avoiding further generation of noise due to unbalanced weight of the fan impeller, etc. At the same time, multiple groups of nested arc-shaped retaining rings can also effectively prevent the integrated stove from emitting odors back into the kitchen.

The servo motor can be used to adjust the orientation of the smoking port at the top of the noise reduction component. When the smoking port rotates to one side of the partition plate, it is beneficial to efficiently extract the oil fume from one side of the partition plate into the interior of the noise reduction component, which can effectively improve the actual utilization rate of the range hood, thereby reducing unnecessary energy waste.

[0020] 4. In this technical solution, multiple groups of rectangular frames with brushes and water spraying holes are arranged inside the noise reduction component, and a water pump, a water suction pipe, a water delivery pipe, and a horizontal pipe for delivering detergent into the rectangular frames are provided.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 7 , in the embodiment of the present invention, a silent integrated stove includes structures such as an integrated stove body 10, a smoking box 11, a noise reduction component 30, and a limit frame 40. A smoke exhaust component 20 is fixedly installed inside the integrated stove body 10. The smoke exhaust component 20 can be a common structure such as a fan in the prior art. The smoking box 11 is fixedly installed on the back of the integrated stove body 10. The smoke exhaust component 20 communicates with the inner cavity of the smoking box 11. A smoking window 12 is provided on the front of the smoking box 11. A noise reduction component 30 with a smoking port 13 opened on the outer circle is rotatably installed inside the smoking box 11. The center of the noise reduction component 30 is rotatably connected to a support frame 14 fixedly connected to the smoking box 11. A servo motor 15 with an output end connected to the center of the noise reduction component 30 is fixedly installed inside the support frame 14. A ventilation window 16 for communicating the smoke exhaust component 20 and the noise reduction component 30 is opened inside the smoking box 11. The limit frame 40 is fixedly installed inside the smoking box 11. An accommodation cavity for the noise reduction component 30 to rotate is provided inside the limit frame 40. The upper half structure of the limit frame 40 is used to guide the smoking direction of the smoking port 13 at the top of the noise reduction component 30.

[0031] Other components such as other control devices necessary inside the integrated range hood body 10 are all prior arts and will not be elaborated here. When the silent integrated range hood is in actual use, the smoke exhaust component 20 absorbs the oil fume generated during the use of the range hood through the ventilation window 16 and the noise reduction component 30 from the smoke suction window 12. The noise generated during the operation of the smoke exhaust component 20 can be efficiently reduced through the noise reduction component 30. When both side cooktops are in use, the smoke suction ports 13 at the top of the noise reduction component 30 are located at the center of the smoke suction window 12. When the operator uses a single-side cooktop to cook rice, the operator can control the servo motor 15 to start through existing components such as the corresponding touch control buttons of the integrated range hood. The servo motor 15 can drive the noise reduction component 30 to rotate, and turn the smoke suction port 13 at the top of the noise reduction component 30 to the position corresponding to the used cooktop of the smoke suction window 12. The limit frame 40 can also guide the smoke suction direction of the smoke suction port 13. The smoke exhaust component 20 makes the wind concentrate on the oil fume generated during the use of a single-side cooktop through the noise reduction component 30 and the smoke suction port 13, which is beneficial to improving the actual working efficiency of the smoke exhaust component 20.

[0032] Furthermore, the silent integrated range hood further includes a cleaning component 50. The cleaning component 50 includes a washing component 501 installed inside the noise reduction component 30. The outer ring of the washing component 501 fits the inner cavity surface of the noise reduction component 30. A pumping component 502 for delivering detergent to the washing component 501 is fixedly installed inside the integrated range hood body 10 and the smoke suction box 11. When the integrated range hood needs to be cleaned after being used for a period of time, start the pumping component 502 to pump the external detergent to the washing component 501. The washing component 501 can spray the detergent into the inside of the noise reduction component 30. Start the motor to drive the noise reduction component 30 to rotate. The inner wall of the noise reduction component 30 rotates while fitting the outer ring of the washing component 501, which can achieve efficient automatic cleaning of the oil stains attached to the inner wall of the noise reduction component 30. And when the noise reduction component 30 with the external smoke suction port 13 rotates and washes, the dirty water inside it can be automatically discharged from the bottom.

[0033] In one embodiment, refer to Figures 1 to 6 , specifically, the noise reduction component 30 includes a front cover 301 and a rear cover 302 close to the inner wall of the smoke suction box 11. A first retaining ring 303, a second retaining ring 304, and a third retaining ring 305 are respectively welded between the front cover 301 and the rear cover 302, which are arranged in sequence from the inner ring to the outer ring. A support tube 306 that is rotationally connected to the outer circle of the support frame 14 is welded at the center of the front cover 301 and the rear cover 302, and the center of the support tube 306 is fixedly connected to the output end of the servo motor 15. The ventilation window 16 penetrates the front cover 301 and is located between the first retaining ring 303 and the support tube 306. Smoke suction ports 13 are opened at the tops of the first retaining ring 303 and the third retaining ring 305, and a smoke suction port 13 is opened at the bottom of the second retaining ring 304. A plurality of communication grooves for accommodating the pumping component 502 are opened in the front cover 301.

[0034] When the smoke exhaust assembly 20 is operating, the oil fume extracted from the smoking window 12 passes through the smoking port 13 and circulates through the third baffle ring 305, the second baffle ring 304, and the first baffle ring 303. The multiple groups of baffle rings increase the obstacle area, and by using the principle of sound wave reflection, etc., the propagation of noise can be effectively reduced. Blocking the direct propagation path of noise can achieve efficient noise reduction and improve the comfort of actual use for users of the integrated stove. The annular member on the support frame 14 can be rotatably connected to the inner ring of the support pipe 306 through a bearing. When the servo motor 15 operates, it drives the overall structure of the support pipe 306 and the noise reduction assembly 30 to rotate inside the limit frame 40, and the smoking port 13 on the third baffle ring 305 can be rotated to the corresponding position for using the stove on one side, effectively improving the flexibility of the integrated stove during actual use.

[0035] Refer to Figures 1 to 5 , correspondingly, the limit frame 40 includes two groups of symmetric arc plates 401 with the inner circle close to the outer circle of the third baffle ring 305. The tops of the two groups of arc plates 401 are both connected by inclined plates 402 to side baffle plates 403 installed on the side of the smoking window 12. A partition plate 404 with the bottom end close to the top end of the noise reduction assembly 30 is provided at the center of the smoking window 12. The arc plates 401, the side baffle plates 403, and the partition plate 404 are all welded to the inner wall of the smoking box 11. The two groups of symmetric arc plates 401 can provide a corresponding rotation space for the noise reduction assembly 30, and structures such as the inclined plates 402 and the side baffle plates 403 can prevent the wind force at the top of the noise reduction assembly 30 from escaping to both sides, which is used to limit the specific smoking direction of the smoking port 13 at the top of the noise reduction assembly 30. The inclined plates 402 are welded to the components they are connected to. The partition plate 404 symmetrically splits the smoking window 12, and the smoking port 13 at the top of the third baffle ring 305 can be rotated to the space between the partition plate 404 and the inclined plate 402 and the side baffle plate 403 on one side, which is conducive to efficiently extracting the oil fume from the smoking window 12 on one side of the partition plate 404.

[0036] Among them, two groups of symmetric auxiliary rollers 17 are rotatably installed inside the smoking box 11. The two groups of auxiliary rollers 17 are respectively installed at the bottom ends of the two groups of arc plates 401, and both groups of auxiliary rollers 17 are in contact with the outer circle of the third baffle ring 305. The outer circle of the third baffle ring 305 can rotate on the two groups of auxiliary rollers 17. The auxiliary rollers 17 can provide effective auxiliary support for the noise reduction assembly 30 and improve the overall stability of the noise reduction assembly 30 during rotation and cleaning. A ventilation pipe 18 is connected between the smoke exhaust assembly 20 and the ventilation window 16. A vertical rod 19 supporting the pumping assembly 502 is welded to the inner circle of the ventilation pipe 18, which can provide auxiliary support for components such as the pumping assembly 502 and is convenient for connecting structures such as the smoke exhaust assembly 20 and the noise reduction assembly 30. A net 110 is installed inside the ventilation window 16. The net 110 can prevent large pieces of oil stains generated during the self-cleaning of the integrated stove from entering the smoke exhaust assembly 20. A communication groove for the pumping assembly 502 to pass through is left between the inner circle of the net 110 and the front cover 301.

[0037] Based on the above embodiments, refer to Figures 1 to 7 , specifically, the pumping assembly 502 includes a water pump 5021 fixedly installed inside the integrated stove body 10. The input end of the water pump 5021 is communicated with a water suction pipe 5022 extending to the outside of the integrated stove body 10. The output end of the water pump 5021 is communicated with a water delivery pipe 5023 that penetrates through the ventilation pipe 18 and extends to the outside of the integrated stove body 10. The water delivery pipe 5023 is communicated with the washing assembly 501 through a plurality of horizontal pipes 5024 penetrating through the communication groove. Among them, the washing assembly 501 includes a plurality of rectangular frames 5011 installed between two adjacent retaining rings or between the first retaining ring 303 and the support pipe 306. The inner cavity of the rectangular frame 5011 is communicated with the end of the horizontal pipe 5024. A brush 5012 that fits the surfaces of the retaining cover, the retaining ring, and the support pipe 306 is provided on the outer ring of the rectangular frame 5011. A plurality of water spraying holes 5013 are opened on the outer ring of the rectangular frame 5011.

[0038] When the noise reduction assembly 30 rotates as a whole, start the water pump 5021. When the integrated stove is assembled, the end of the water suction pipe 5022 can be connected to a washing liquid pool, etc. The water pump 5021 uses the water suction pipe 5022, the water delivery pipe 5023, and the horizontal pipe 5024 to pump the washing liquid to the rectangular frame 5011. The rectangular frame 5011 sprays the detergent into the noise reduction assembly 30 through the water spraying holes 5013. The surface of the rotating internal components of the noise reduction assembly 30 fits the brush 5012 on the outer ring of the rectangular frame 5011. The brush 5012, combined with the washing liquid, can efficiently and automatically clean the inside of the noise reduction assembly 30. An automatic laundry detergent extraction structure used in a washing machine in the prior art can be assembled inside the integrated stove body 10 or the smoking box 11. The water suction pipe 5022 is connected to an external water pipe and the above structure, etc., to achieve automatic proportioning of detergent and water, further improving the flexibility of the device. Or a water tank mixed with a cleaning agent is directly assembled inside the integrated stove body 10 or the smoking box 11. The water suction pipe 5022 is connected to the corresponding water tank inside, facilitating the user to automatically proportion detergent and water, etc.

[0039] Correspondingly, an inclined guide plate 111 is installed at the bottom of the inner cavity of the smoking box 11. One side of the smoking box 11 is communicated with a sewage discharge pipe 112 located at the bottom end of the inclined guide plate 111. When the noise reduction assembly 30 rotates and is washed, the smoking port 13 provided on its outermost ring can automatically pour the cleaning sewage onto the inclined guide plate 111. The sewage on the inclined guide plate 111 can be transported to the outside of the device through the sewage discharge pipe 112. The sewage discharge pipe 112 can be connected to a corresponding sewer pipe in the kitchen, etc.
