[0002] As an innovation in kitchen appliances, the integrated stove integrates multiple functional modules such as gas stoves, electromagnetic stoves, disinfection cabinets, and range hoods into one, realizing an integrated kitchen solution. The integrated stove can be divided into three parts: the head, the fan system, and the cooking system. At present, the performance improvement of the integrated stove is mostly focused on the fan system, while the research on its head structure is ignored. The head of the integrated stove can usually be divided into two parts: the upper suction chamber and the rear suction channel. The upper suction chamber is located above the rear suction channel. The upper suction chamber has a filter. The oil smoke generated during the cooking process first enters the upper suction chamber through the oil filter under the negative pressure generated by the fan system, and then enters the rear suction channel downward, and then passes through the bellows and the air outlet duct in turn to be discharged into the atmosphere. The traditional integrated stove head design mainly focuses on the appearance design, and there is little optimization of the internal flow channel of the head. At the same time, the integrated stove head needs to be disassembled and cleaned regularly, which affects the user experience.

At the same time, the flow of oil fumes in the head is optimized and a self-cleaning function module design is provided.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: An integrated stove head device with flow control noise reduction and self-cleaning functions comprises an integrated stove head shell, wherein the integrated stove head shell comprises a front baffle, a side plate, a rear baffle and a top plate arranged above the rear baffle, wherein the front baffle, the side plate and the rear baffle together constitute a head suction air duct; an oil filter is arranged between the front baffle and the rear baffle, a temperature sensor is arranged on the top of the rear baffle, and a guide plate assembly is arranged on the inner side of the front baffle, for optimizing and guiding the oil smoke flow channel and realizing the self-cleaning function.

[0011] Further technical solution, the flow control noise reduction function is achieved by parameterizing the structure and position of the guide plate, and optimizing different structures and positions of the guide plate. The guide plate parameter design 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 optimization process is as follows: 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 L 1 , the inner side of the head air intake duct is L 2 , so that L 1 With L 2 If they intersect at point O, then take point O as the origin and follow L 1 The direction is set to the X axis to move along the L 2 The direction is set as the Z axis, which is perpendicular to both the X and Z axes and the height direction through point O is set as the Y axis, thereby establishing a spatial rectangular coordinate system; S2: Take 8 points on the front baffle of the head, namely A(x 1 ,z 1 )、B(x 2 ,z 2 )、C(x 3 ,z 3 )、D(x 4 ,z 4 )、E(x 5 ,z 5 )、F(x 6 ,z 6 )、G(x 7 ,z 7 )、H(x 8 ,z 8 );where L2 is the total height of the head side, L 1 For the bottom, L 3 is the total thickness of the head; OA, AB, BC, BD, DE, EF, FG, and FH are all straight line segments; point O is the origin of the coordinate axis, that is, O(0,0); since segment OA is along the Z axis, the coordinates of point A can be known as (0, Z 1 );Segments AB and BC are along the X-axis, so the coordinates of point B (x 1 ,z 1 )、Point C coordinates(x 2 ,z 1 ); Since BD and DE segments are along the Z axis, the coordinates of point D (x 1 ,z 2 ), coordinates of point E (x 1 ,z 3 ); Since the EF and FG segments are horizontal, the coordinates of point F (x 3 ,z 3 ), coordinates of point G (x 4 ,z 3 ); Because the FH and HM segments are perpendicular, the coordinates of point H (x 3 ,z 4 ), coordinates of point M (x 3 ,L 2 ); where x 1 +x 2 =x 3 +x 4 =L 1 , whereby the guide plate position and length coordinates are completely defined; S3: Take 4 points on the side of the head, which are I(y 1 ,z 1 )、J(y 2 ,z 2 )、K(y 3 ,z 3 )、L(y 4 ,z 4 ), because IJ and KL segments are along the Y axis, IK along the Z axis, the coordinates of point K (0, z 5 ), point I coordinates (0,z 6 ), coordinates of point L (-y 1 ,z 5 ), point J coordinates (-y 2 ,z 6 ); The thickness of the guide plate is thus completely defined; S4: The guide plate profile determined by the above sample points is geometrically modeled using 3D design software, and simulation calculations are performed to obtain the outlet air volume and noise values ​​of each model; the functional relationship between the design variables and the outlet air volume and noise is established based on the approximate model, and the determination coefficient R is used to determine the relationship between the design variables and the outlet air volume and noise. 2 Evaluate the accuracy of the established approximate model, determine the final approximate model, use the optimization algorithm to optimize the approximate model, determine the relevant parameters of the guide plate based on the optimal solution obtained, perform final geometric modeling using 3D software, and complete the optimization process.

[0012] In summary, simulation is performed according to the defined parameters of the rear guide vane, and optimization is performed based on the overall streamline (the overall streamline has no obvious vortex) and the size of the turbulent kinetic energy. Different airflow inlet angles under different models are matched to achieve improved air performance of the entire machine and optimized noise performance.

[0013] Further technical solution, the self-cleaning function is achieved by adjusting the position of the guide plate and heating the heating tube electrically, which specifically includes two working modes: In cleaning mode, the heating tube starts, the guide plate position is adjusted by the slide rail and telescopic motor, the head is cleaned as a whole, the fan system starts to take away the dissolved grease and heat the whole body with hot air, the larger oil droplets are collected into the oil collecting bucket of the air outlet pipe under the action of gravity, and the smaller particles are directly discharged; In preheating mode, the preheating mode is linked with the external temperature sensor to adjust the working power of the resistance wire according to the actual ambient temperature. In winter, the ambient temperature is low, the resistance wire increases the power, heats the inlet air, and preheats the whole through the fan system. In summer, the ambient temperature is high, the resistance wire is low power or does not operate, and the unit is simply preheated.

[0014] On the other hand, the present invention also proposes an integrated stove with a self-cleaning head, comprising an integrated stove head device with flow control noise reduction and self-cleaning functions and an integrated stove box as described above, wherein the integrated stove head device is fixed to the upper part of the integrated stove box by bolts, and a stove top is provided on the upper part of the integrated stove box, and a steamer and a fan system are provided inside.

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] like Figure 1-Figure 11 As shown, an integrated stove head device with flow control noise reduction and self-cleaning functions, the integrated stove head device is fixed to the upper part of the integrated stove box by bolts, and includes an integrated stove head shell 1 and a guide plate assembly arranged on the integrated stove head shell 1; The integrated stove head housing 1 includes a front baffle 11, a side panel 12, a rear baffle 14, and a top panel 14 arranged above the rear baffle 13; an oil filter 2 is arranged between the front baffle 11 and the rear baffle 14, a temperature sensor 7 is arranged on the top of the rear baffle 13, and a guide plate assembly is arranged on the inner side of the front baffle 11 to optimize and guide the oil smoke flow channel and realize the self-cleaning function. The guide plate assembly includes two guide plates 6 arranged in parallel on the inner side of the front baffle 11, and the surface of the guide plate 6 is arranged in an arc shape; the integrated stove head housing 1 is rectangular as a whole and cooperates with the guide plate assembly to form a head suction air duct.

[0023] In order to adjust the position of the guide plate 6, the front baffle 11 is provided with slide rails 3 on both sides, the slide rails 3 have built-in sliding rods 4, and the sliding rods 4 are also connected to telescopic motors 5 by bolts, and the guide plate assembly is connected to the telescopic motors 5. The telescopic motors 5 are connected to the sliding rods 4 on the front baffle 11 by bolts, and the specific height of the guide plate 6 in the non-smoke exhaust state is adjusted by the sliding rods 4.

[0024] 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, so that the plate body can be replaced.

[0025] The heating tube 62 includes a tube body 621 and a resistance wire 622 wound on the tube body 621 ; the guide plate 62 has a built-in heating tube 62 , which generates heat by winding the resistance wire 622 on the tube, and the specific power of the resistance wire 622 is controlled according to the external temperature sensor 7 .

[0026] The two ends of the heating tube 62 are respectively connected to the telescopic motor 5. The front and rear adjustment of the guide plate 6 is achieved through the action of the telescopic motor 5. The up and down adjustment of the telescopic motor 5 is achieved through the rotation of the sliding rod 4, thereby achieving the up and down adjustment of the guide plate 6.

[0027] There are two head guide plates 6, the first guide plate is close to the integrated stove box side, and the second guide plate is far away. In the optimization process, there is no absolute size relationship between the structural parameters of the two guide plates 6, and both are used as adjustable parameters.

[0028] The design of the guide block 6 is controlled by four variables: guide plate length, guide plate thickness, guide plate spacing, and guide plate-head distance. The steps for defining the position and structure of the guide plate 6 are as follows and refer to the attached Fig.12 : (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 L 1 , the inner side of the head air duct is L 2 , so that L 1 With L 2 If they intersect at point O, then take point O as the origin and follow L 1 The direction is set to the X axis to move along the L 2 The direction is set as the Z axis, which is perpendicular to both the X and Z axes and the height direction through point O is set as the Y axis, thereby establishing a spatial rectangular coordinate system; (S2) Take 8 points on the front baffle of the head, namely A(x 1 ,z 1 )、B(x 2 ,z 2 )、C(x 3 ,z 3 )、D(x 4 ,z 4 )、E(x 5 ,z 5 )、F(x 6 ,z 6 )、G(x 7 ,z 7 )、H(x 8 ,z 8 );where L 2 is the total height of the head side, L 1 For the bottom, L 3is the total thickness of the head; OA, AB, BC, BD, DE, EF, FG, and FH are all straight line segments; point O is the origin of the coordinate axis, that is, O(0,0); since segment OA is along the Z axis, the coordinates of point A can be known as (0, Z 1 );Segments AB and BC are along the X-axis, so the coordinates of point B (x 1 ,z 1 )、Point C coordinates(x 2 ,z 1 ); Since BD and DE segments are along the Z axis, the coordinates of point D (x 1 ,z 2 ), coordinates of point E (x 1 ,z 3 ); Since the EF and FG segments are horizontal, the coordinates of point F (x 3 ,z 3 ), coordinates of point G (x 4 ,z 3 ); Because the FH and HM segments are perpendicular, the coordinates of point H (x 3 ,z 4 ), coordinates of point M (x 3 ,L 2 ).

[0029] x 1 +x 2 =x 3 +x 4 =L 1 , whereby the guide vane position and length coordinates are fully defined.

[0030] (S3) Take 4 points on the side of the head, which are I(y 1 ,z 1 )、J(y 2 ,z 2 )、K(y 3 ,z 3 )、L(y 4 ,z 4 ), because IJ and KL segments are along the Y axis, IK along the Z axis, the coordinates of point K (0, z 5 ), point I coordinates (0,z 6 ), coordinates of point L (-y 1 ,z 5 ), point J coordinates (-y 2 ,z 6 ); The thickness of the guide plate is thus completely defined. When setting the parameters here, the length of each straight line segment can be 0. In the optimization process, the situation where the two guide plates are in direct contact cannot be ignored, that is, the two guide plates are assembled into a trapezoidal or rectangular guide plate.

[0031] (S4) The guide plate profile determined by the sample points is geometrically modeled using 3D design software, and simulation calculations are performed to obtain the outlet air volume and noise values ​​of each model; the functional relationship between the design variables and the outlet air volume and noise is established based on the approximate model, and the determination coefficient R is used to determine the relationship between the design variables and the outlet air volume and noise. 2 Evaluate the accuracy of the established approximate model, determine the final approximate model, use the optimization algorithm to optimize the approximate model, determine the relevant parameters of the guide plate based on the optimal solution obtained, and perform the final geometric modeling using 3D software.

[0032] In summary, simulation is performed according to the defined parameters of the rear guide vane, and optimization is performed based on the overall streamline (the overall streamline has no obvious vortex) and the size of the turbulent kinetic energy. Different airflow inlet angles under different models are matched to achieve improved air performance of the entire machine and optimized noise performance.

[0033] The edge of the guide plate is in an arc shape. According to the wall attachment effect, the oil smoke can flow along the arc of the guide plate, thereby improving the guiding effect of the guide plate on the oil smoke.

[0034] Another object of the present invention is to provide an integrated stove with a self-cleaning head, comprising the integrated stove head device with flow control and noise reduction and an integrated stove box, wherein the integrated stove head device is fixed to the upper part of the integrated stove box by bolts. The integrated stove box is rectangular in shape as a whole, including an integrated stove top, a fan, an air duct, an air outlet pipe, etc.; The integrated stove has a built-in fan system 8, including a volute, a motor, an impeller, and a collector. The integrated stove head device is located above the integrated stove body and is fixed to the integrated stove body with bolts; a stovetop 21 is arranged on the upper part of the integrated stove body, and a steam box 31 and a fan system 8 are arranged inside.

[0035] The integrated stove box also includes air outlets 9 arranged on the left and right sides of the integrated stove, and is matched with an air outlet pipe 10; the outlet of the fan system 8 is connected to the air outlet pipe 10; the direction of the air outlet 9 can be changed according to the left and right arrangement of the integrated stove. An oil collecting bucket 101 is arranged on the air outlet pipe 10.

[0036] The integrated stove head device is built with a guide plate 6, and the structure and position of the guide plate 6 are determined based on flow control theory.

[0037] The self-cleaning function module of the device of the present application can be divided into two working modes, referring to Figure 7 and Figure 8As shown, in the cleaning mode, the heating tube 62 is started, 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 to achieve the height adjustment of the telescopic motor 5, thereby driving the guide plate 6 to adjust its height; the distance adjustment is achieved by the extension and retraction of the electromagnetic telescopic rod of the telescopic motor 5 to adjust the distance of the guide plate 6. The guide plate 6 cleans the head as a whole, and the fan system 8 is started to take away the dissolved grease and heat the whole by hot air. Larger oil droplets are collected in the oil collecting bucket 101 of the air outlet pipe 10 under the action of gravity, and smaller particles are directly discharged.

[0038] The preheating mode is linked with the external temperature sensor 7 to adjust the working power of the resistance wire according to the actual ambient temperature. In winter, the ambient temperature is low, the resistance wire increases the power to heat the inlet air, and the whole is preheated through the fan system 8. In summer, the ambient temperature is high, the resistance wire is low power or does not operate, and the unit is simply preheated.

[0039] The self-cleaning module is briefly described as follows: 1. The heating tube 62 in the guide plate 6 is started, and the guide plate 6 is moved up and down by the slide rail 3, and the guide plate 6 is pushed forward and backward by the telescopic motor 5, so that the overall temperature of the head area rises rapidly, and the adhering grease is quickly dissolved. 2. After the head is heated for 5-10 minutes, the fan system 8 is started to take away the dissolved grease and heat the whole body with hot air. Large oil droplets are collected in the oil collecting bucket 101 of the air outlet pipe 10 under the action of gravity, and smaller particles are directly discharged.

[0040] Fig.13 This is a schematic diagram comparing the flow of oil smoke between the prototype head and the new head of the integrated stove provided by the present invention. From the comparison, it can be seen that due to the setting of the guide plate, the oil smoke streamline is improved, the energy loss is reduced, and the noise reduction effect is produced.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
