Description

An integrated stove head device with flow control, noise reduction, and self-cleaning functions, and an integrated stove Technical Field

[0001] This invention belongs to the field of integrated stove technology, specifically relating to an integrated stove head device with flow control noise reduction and self-cleaning functions, and an integrated stove. Background Technology

[0002] Integrated cooktops, as an innovation in kitchen appliances, combine multiple functional modules such as gas stoves, induction cooktops, disinfection cabinets, and range hoods into one unit, achieving a unified kitchen solution. An integrated cooktop can be divided into three parts: the cooktop itself, the fan system, and the cooking system. Currently, performance improvements in integrated cooktops are mostly focused on the fan system, neglecting research on its cooktop structure. The cooktop head typically consists of two parts: an upper suction chamber and a rear suction duct, with the upper suction chamber located above the rear suction duct. The upper suction chamber has a filter; during cooking, fumes generated by the fan system first pass through the filter into the upper suction chamber, then flow downwards into the rear suction duct, and finally pass through the air box and exhaust duct before being discharged into the atmosphere. Traditional integrated cooktop cooktop designs primarily focus on aesthetics, with little optimization of the internal flow channels. Furthermore, the cooktop head requires regular disassembly and cleaning, impacting the user experience.

[0003] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0004] (1) The head of the integrated stove needs to be disassembled and cleaned regularly, lacking a self-cleaning head working mode to improve the user experience.

[0005] (2) Traditional integrated stove head design mainly focuses on appearance design, with little research on optimizing the internal flow field of the head. Technical issues

[0006] To address the aforementioned issues, this invention provides an integrated stove head device with flow control noise reduction and self-cleaning functions, which reduces the operating noise of the integrated stove when extracting oil fumes. At the same time, it optimizes the flow of oil fumes at the head and has a self-cleaning module design. Technical solutions

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An integrated stove head device with flow control noise reduction and self-cleaning functions includes an integrated stove head shell, which includes a front baffle, a side plate, a rear baffle, and a top plate disposed above the rear baffle. The front baffle, side plate, and rear baffle together form the head air intake duct. An oil filter screen is disposed between the front baffle and the rear baffle, a temperature sensor is disposed on the top of the rear baffle, and a guide plate assembly is disposed on the inner side of the front baffle to optimize and guide the oil fume flow and achieve the self-cleaning function.

[0009] In a further technical solution, slide rails are provided on both sides of the front baffle, and sliding rods are built into the slide rails. A telescopic motor is also connected to the sliding rods by bolts, and the guide plate assembly is connected to the telescopic motor.

[0010] In a further technical solution, the deflector assembly includes two deflectors arranged in parallel on the inner side of the front baffle, and the outer surface of the deflector is arc-shaped.

[0011] In a further technical solution, the guide plate includes a guide plate body and a heating element. The connection between the guide plate body and the heating element is a snap-fit ​​structure, which allows for plate body replacement.

[0012] In a further technical solution, the heating element includes a tube body and a resistance wire wound around the tube body; both ends of the heating element are connected to a telescopic motor, and the front and back adjustment of the guide plate is realized by the action of the telescopic motor, and the up and down adjustment of the telescopic motor is realized by the rotation of the sliding rod, thereby realizing the up and down adjustment of the guide plate.

[0013] A further technical solution involves optimizing the flow control noise reduction function by parameterizing the structure and position of the guide vane. The guide vane parameters are controlled by four variables: guide vane length, guide vane thickness, guide vane spacing, and the distance between the guide vane and the head. The specific optimization process is as follows:

[0014] S1: Establish a spatial rectangular coordinate system, define the position of the guide plate and the structural parameters of the guide plate; let the lower long side of the head air intake duct be L1, and the inner side of the head air intake duct be L2, so that L1 and L2 intersect at point O. Then, take point O as the origin, set the direction along L1 as the X-axis, set the direction along L2 as the Z-axis, and set the direction perpendicular to both the X and Z axes and passing through point O along the height direction as the Y-axis, thereby establishing a spatial rectangular coordinate system.

[0015] S2: Take 8 points on the front baffle of the head, namely A(x1,z1), B(x2,z2), C(x3,z3), D(x4,z4), E(x5,z5), F(x6,z6), G(x7,z7), and H(x8,z8); where L2 is the total height of the head side, L1 is the bottom side, and L3 is the total thickness of the head; segments OA, AB, BC, BD, DE, EF, FG, and FH are all straight line segments; point O is the origin of the coordinate axis, i.e., O(0,0); since segment OA is along the Z-axis, the coordinates of point A can be known as (0,...). Z1); Since segments AB and BC are along the X-axis, the coordinates of point B are (x1, z1) and point C is (x2, z1); Since segments BD and DE are both along the Z-axis, the coordinates of point D are (x1, z2) and point E is (x1, z3); ​​Since segments EF and FG are horizontal, the coordinates of point F are (x3, z3) and point G is (x4, z3); ​​Since segments FH and HM are perpendicular, the coordinates of point H are (x3, z4) and point M is (x3, L2).

[0016] Where x1+x2=x3+x4=L1, the position and length coordinates of the guide vane are thus completely defined;

[0017] S3: Take four points on the side of the head, namely I(y1,z1), J(y2,z2), K(y3,z3), and L(y4,z4). Since segments IJ and KL are along the Y-axis and IK is along the Z-axis, the coordinates of point K are (0,z5), point I is (0,z6), point L is (-y1,z5), and point J is (-y2,z6). Thus, the thickness of the guide vane is completely defined.

[0018] S4: The guide vane profile determined by the above sample points is geometrically modeled using 3D design software, and simulation calculations are performed to obtain the outlet airflow and noise values ​​for each model; a functional relationship between design variables and outlet airflow and noise is established based on the approximate model, and the determination coefficient R is used... 2 The accuracy of the established approximate model is evaluated, the final approximate model is determined, the approximate model is optimized using an optimization algorithm, the relevant parameters of the guide vane are determined based on the optimal solution obtained from the optimization, and the final geometric modeling is performed using 3D software to complete the optimization process.

[0019] In summary, simulations were performed based on the defined parameters of the guide vane. Optimization was achieved by considering the overall streamline (without obvious vortices) and turbulent kinetic energy, and different airflow inlet angles were matched for different models to improve the overall aerodynamic performance and optimize noise levels.

[0020] A further technical solution is that the self-cleaning function is achieved by adjusting the position of the guide plate and heating the heating element, specifically including two working modes:

[0021] In cleaning mode, the heating element is activated, and the position of the guide plate is adjusted by the slide rail and telescopic motor to clean the head as a whole. The fan system is activated to remove dissolved grease and heat the whole body with hot air. Larger oil droplets are collected in the oil collection hopper of the air outlet under the action of gravity, while smaller particles are discharged directly.

[0022] In preheating mode, the preheating mode is linked with the external temperature sensor and adjusts the working power of the resistance wire according to the actual ambient temperature. In winter, when the ambient temperature is low, the resistance wire increases its power to heat the inlet air and preheat the whole unit through the fan system. In summer, when the ambient temperature is high, the resistance wire operates at low power or not at all to perform simple preheating of the unit.

[0023] On the other hand, the present invention also proposes an integrated stove with a self-cleaning head, including an integrated stove head device with flow control noise reduction and self-cleaning functions as described above, and an integrated stove body. The integrated stove head device is fixed to the upper part of the integrated stove body by bolts. The upper part of the integrated stove body is provided with a stove platform, and a steam oven and a fan system are provided inside.

[0024] A further technical solution includes air vents located on the left and right sides of the integrated stove, and air ducts are provided in conjunction with them; the outlet of the fan system is connected to the air ducts; the orientation of the air vents can be changed according to the left and right arrangement of the integrated stove. An oil collection hopper is provided on the air duct. Beneficial effects

[0025] Based on the above technical solutions and the technical problems solved, the beneficial effects of the technical solution to be protected by this invention are as follows:

[0026] (1) This invention provides a novel design method for noise reduction head of integrated stove by parameterizing the structure and position of the guide plate and optimizing different structures and positions of the guide plate through flow optimization theory.

[0027] (2) The self-cleaning integrated stove designed in this invention uses a self-heating movable guide plate to clean the head of the integrated stove, and transports hot air through a fan system to clean the whole, eliminating the trouble of multiple disassembly and cleaning, and improving the user experience.

[0028] (3) The head guide plate designed in this invention has a certain curvature. Based on the Coanda effect, the cleaning steam moves along the guide plate, which improves the cleaning effect.

[0029] (4) The self-heating movable guide plate designed in this invention is linked with the head temperature sensor to adjust the heating of the resistance wire according to the ambient temperature, and selectively preheats the unit. Attached Figure Description

[0044] Type the description paragraph of the best embodiment of the invention here. Embodiments of the present invention

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] As shown in Figures 1-11, an integrated stove head device with flow control noise reduction and self-cleaning functions is provided. The integrated stove head device is fixed to the upper part of the integrated stove body by bolts and includes an integrated stove head shell 1 and a guide plate assembly disposed on the integrated stove head shell 1.

[0047] The integrated stove head shell 1 includes a front baffle 11, a side plate 12, a rear baffle 14, and a top plate 14 disposed above the rear baffle 13. An oil filter 2 is disposed between the front baffle 11 and the rear baffle 14. A temperature sensor 7 is disposed on the top of the rear baffle 13. A baffle assembly is disposed on the inner side of the front baffle 11 to optimize and guide the oil fume flow and achieve a self-cleaning function. The baffle assembly includes two parallel baffles 6 disposed on the inner side of the front baffle 11, and the surface of the baffles 6 is arc-shaped. The integrated stove head shell 1 is rectangular in shape and cooperates with the baffle assembly to form a head air intake duct.

[0048] To adjust the position of the air deflector 6, slide rails 3 are provided on both sides of the front baffle 11. Slide rails 3 have built-in sliding rods 4, and telescopic motors 5 are bolted to the sliding rods 4. The air deflector assembly is connected to the telescopic motors 5. The telescopic motors 5 are bolted to the sliding rods 4 on the front baffle 11, and the height of the air deflector 6 in its non-smoke exhaust state is adjusted by the sliding rods 4.

[0049] The guide plate 6 includes a guide plate body 61 and a heating tube 62. The connection between the guide plate body 61 and the heating tube 62 is a snap-fit ​​structure, which allows the plate body to be replaced.

[0050] The heating element 62 includes a tube body 621 and a resistance wire 622 wound around the tube body 621; the guide plate 62 has a built-in heating element 62, which generates heat through the resistance wire 622 wound around the tube, and the specific power of the resistance wire 622 is controlled by an external temperature sensor 7.

[0051] The heating element 62 is connected to the telescopic motor 5 at both ends. The telescopic motor 5 is used to adjust the guide plate 6 back and forth. The sliding rod 4 is rotated to adjust the telescopic motor 5 up and down, thereby adjusting the guide plate 6 up and down.

[0052] There are two head guide plates 6. The first guide plate is closer to the integrated stove body, and the second guide plate is further away. During the optimization process, the structural parameters of the two guide plates 6 do not have an absolute size relationship and are both used as adjustable parameters.

[0053] The design of the guide block 6 is controlled by four variables: guide plate length, guide plate thickness, guide plate spacing, and distance between the guide plate and the head. The specific parameter definition steps for the position and structure of the guide plate 6 are as follows and refer to Figure 12:

[0054] (S1) Establish a spatial rectangular coordinate system, define the position of the guide plate and the structural parameters of the guide plate; let the lower long side of the head air duct be L1, and the inner side of the head air duct be L2, so that L1 and L2 intersect at point O. Then take point O as the origin, set the direction along L1 as the X-axis, set the direction along L2 as the Z-axis, and set the direction perpendicular to both the X and Z axes and passing through point O along the height direction as the Y-axis, thereby establishing a spatial rectangular coordinate system.

[0055] (S2) Take 8 points on the front baffle of the head, namely A(x1,z1), B(x2,z2), C(x3,z3), D(x4,z4), E(x5,z5), F(x6,z6), G(x7,z7), and H(x8,z8); where L2 is the total height of the head side, L1 is the bottom side, and L3 is the total thickness of the head; segments OA, AB, BC, BD, DE, EF, FG, and FH are all straight line segments; point O is the origin of the coordinate axis, i.e., O(0,0); since segment OA is along the Z-axis, the coordinates of point A can be known as (0, Z1); Segments AB and BC are along the X-axis, so the coordinates of point B are (x1, z1) and point C is (x2, z1); Since segments BD and DE are both along the Z-axis, the coordinates of point D are (x1, z2) and point E is (x1, z3); ​​Since segments EF and FG are horizontal, the coordinates of point F are (x3, z3) and point G is (x4, z3); ​​Since segments FH and HM are perpendicular, the coordinates of point H are (x3, z4) and point M is (x3, L2).

[0056] x1+x2=x3+x4=L1, thus the position and length coordinates of the guide vane are completely defined.

[0057] (S3) Take four points on the side of the head, namely I(y1,z1), J(y2,z2), K(y3,z3), and L(y4,z4). Since segments IJ and KL are along the Y-axis and IK is along the Z-axis, the coordinates of point K are (0,z5), the coordinates of point I are (0,z6), the coordinates of point L are (-y1,z5), and the coordinates of point J are (-y2,z6).

[0058] Therefore, the thickness of the guide vane is completely defined. When setting the parameters here, the length of each straight segment can be 0. During the optimization process, the situation where the two guide vanes are in direct contact, i.e., the two guide vanes are combined into a trapezoidal or rectangular guide vane, cannot be ignored.

[0059] (S4) The guide vane profile determined by the sample points is geometrically modeled using 3D design software, and simulation calculations are performed to obtain the outlet airflow and noise values ​​for each model; a functional relationship between the design variables and the outlet airflow and noise is established based on the approximate model, and the determination coefficient R is used to determine the design variables. 2 The accuracy of the established approximate model is evaluated, the final approximate model is determined, the approximate model is optimized using an optimization algorithm, the relevant parameters of the guide vane are determined based on the optimal solution obtained from the optimization, and the final geometric modeling is performed using 3D software.

[0060] In summary, simulations were performed based on the defined parameters of the guide vane. Optimization was achieved by considering the overall streamline (without obvious vortices) and turbulent kinetic energy, and different airflow inlet angles were matched for different models to improve the overall aerodynamic performance and optimize noise levels.

[0061] The edge of the guide plate is arc-shaped. According to the wall adhesion effect, the oil fumes can flow along the arc of the guide plate, thereby improving the guiding effect of the guide plate on the oil fumes.

[0062] Another objective of this invention is to provide an integrated stove with a self-cleaning head, comprising the aforementioned integrated stove head device with flow control and noise reduction, and an integrated stove housing. The integrated stove head device is fixed to the upper part of the integrated stove housing by bolts. The integrated stove housing is generally rectangular in shape and includes the integrated stove top, fan, air duct, air outlet pipe, etc.

[0063] The integrated stove has a built-in fan system 8, which includes a volute, a motor, an impeller, and a collector ring. The integrated stove head device is located above the integrated stove body and is fixed to the integrated stove body with bolts; the upper part of the integrated stove body is provided with a stove platform 21, and the interior is provided with a steam oven 31 and the fan system 8.

[0064] The integrated stove body also includes air outlets 9 located on the left and right sides of the integrated stove, and is equipped with air outlet pipes 10; the outlet of the fan system 8 is connected to the air outlet pipe 10; the orientation of the air outlets 9 can be changed according to the left and right arrangement of the integrated stove. An oil collection hopper 101 is provided on the air outlet pipe 10.

[0065] The integrated stove head device has a built-in guide plate 6, and the structure and position of the guide plate 6 are determined based on flow control theory.

[0066] The self-cleaning module of this application device can be divided into two working modes, as shown in Figures 7 and 8. In the cleaning mode, the heating element 62 is activated, and the position of the guide plate 6 is adjusted by the slide rail 3 and the telescopic motor 5. The height adjustment is achieved by the sliding motor driving the sliding rod 4 to rotate, thereby adjusting the height of the telescopic motor 5 and thus the guide plate 6. The distance adjustment is achieved by the extension and retraction of the electromagnetic telescopic rod of the telescopic motor 5. The guide plate 6 performs overall cleaning of the head. The fan system 8 is activated, which carries away the dissolved grease and heats the whole thing with hot air. Larger oil droplets are collected in the oil collection hopper 101 of the air outlet duct 10 under the action of gravity, while smaller particles are discharged directly.

[0067] The preheating mode is linked with the external temperature sensor 7. The working power of the resistance wire is adjusted according to the actual ambient temperature. In winter, when the ambient temperature is low, the resistance wire increases its power to heat the inlet air and preheat the whole unit through the fan system 8. In summer, when the ambient temperature is high, the resistance wire operates at low power or not at all, and the unit is simply preheated.

[0068] A brief description of the self-cleaning module: 1. The heating element 62 inside the guide plate 6 is activated. The guide plate 6 moves up and down via the slide rail 3 and is pushed back and forth by the telescopic motor 5, causing the overall temperature of the head area to rise rapidly, dissolving the adhering grease quickly. 2. After the head has been heated for 5-10 minutes, the fan system 8 is activated, carrying away the dissolved grease and heating the entire area with hot air. Larger oil droplets are collected in the oil collection hopper 101 of the air outlet duct 10 under gravity, while smaller particles are discharged directly.

[0069] Figure 13 is a schematic diagram comparing the flow of oil fumes between the prototype head and the new head of the integrated stove provided by the present invention. As can be seen from the comparison, the oil fume flow is improved and energy loss is reduced due to the setting of the guide plate, thereby producing a noise reduction effect.

[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
