Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and more particularly, to a grille structure and an integrated stove. Background Art

[0002] The integrated stove has an air intake grille, and a smoke suction port is formed in the air intake grille. Due to appearance requirements, the size of the smoke suction port of the integrated stove is very small. In this way, the air intake area is reduced, so that the air flow velocity at the smoke suction port is very large. The large-velocity air flow impacts on the air intake grille, causing the air intake grille to vibrate violently, and then generating air intake resonance, which will increase the noise during the operation of the integrated stove. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present application provides a grille structure.

[0005] A second aspect of the present application provides an integrated stove.

[0006] In view of this, a first aspect of the present application provides a grille structure for an integrated stove, including: a frame, the inner peripheral surface of the frame includes a first side surface and a second side surface arranged opposite to each other; a flow guiding rib, connected between the first side surface and the second side surface, and a plurality of smoke suction ports are enclosed by the flow guiding rib and the inner peripheral surface of the frame; along the windward side to the leeward side of the frame, the flow guiding rib includes a windward section, a leeward section and a connecting section, the connecting section is connected between the windward section and the leeward section, in the longitudinal section of the flow guiding rib, the outer contour line of the windward section is a first arc segment, the outer contour line of the leeward section is a second arc segment, and the radius corresponding to the first arc segment is smaller than the radius corresponding to the second arc segment; along the windward section to the leeward section, the distance between the outer contour lines on both sides of the connecting section gradually increases; wherein, the longitudinal section of the flow guiding rib is perpendicular to the direction from the first side surface to the second side surface.

[0007] A grille structure provided by the present application includes a frame and a flow guiding rib.

[0008] The frame has an inner peripheral surface, and the inner peripheral surface includes a first side surface and a second side surface, and the first side surface and the second side surface are opposite and spaced apart.

[0009] The flow guiding rib is connected to the inner peripheral surface of the frame. Specifically, the flow guiding rib is connected to the first side surface and the flow guiding rib is connected to the second side surface. That is to say, the flow guiding rib is connected between the first side surface and the second side surface.

[0010] It can be understood that a plurality of smoke suction ports are enclosed by the flow guiding rib and the inner peripheral surface of the frame.

[0011] Further, the frame has a windward side and a leeward side which are oppositely arranged, and the flue gas flows from the windward side to the leeward side. The flow guiding rib includes a windward section, a leeward section and a connecting section. The connecting section is connected to the windward section and the leeward section, that is, the connecting section is connected between the windward section and the leeward section.

[0012] Taking a cross-section of the flow guiding rib in a direction perpendicular to the first side surface to the second side surface, in the longitudinal section of the flow guiding rib, the outer contour line of the windward section is a first arc segment, and the outer contour line of the leeward section is a second arc segment. The radius corresponding to the first arc segment is smaller than the radius corresponding to the second arc segment. And along the windward section to the leeward section, the distance between the two outer contour lines of the connecting section gradually increases. It can be seen from this that the outer surface of the windward section is an arc surface, the outer surface of the leeward section is an arc surface, and the size of the outer surface of the windward section is different from the size of the outer surface of the leeward section.

[0013] By reasonably setting the cooperation structure of the windward section, the connecting section and the leeward section, while ensuring the manufacturability of the product, the resistance to high-speed airflow can be reduced. The airflow will not directly impact the grille structure, but will flow around under the action of the outer shape of the flow guiding rib. In this way, the impact energy of the airflow is reduced, which will greatly reduce the noise during the operation of the integrated range hood and improve the use performance and market competitiveness of the product.

[0014] It can be understood that the outer surface of the windward section is an arc surface. This setting enables the windward section to not only reduce the resistance to high-speed airflow, but also facilitate the demolding of the grille structure, with processing feasibility and convenience.

[0015] It can be understood that the outer surface of the leeward section is an arc surface, and along the windward section to the leeward section, the distance between the two outer contour lines of the connecting section gradually increases. The leeward section and the connecting section cooperate to change the flow path of the airflow, and can produce an effective flow-around resistance reduction effect, which is beneficial to reducing the operation noise of the integrated range hood. More specifically, the connecting section and the leeward section cooperate to play a role in guiding the flow. When the airflow passes through the uniformly changing connecting section and leeward section, the vortices of the airflow can be reduced, and further reduce the noise during the operation of the integrated range hood.

[0016] It can be understood that the radius corresponding to the first arc segment is smaller than the radius corresponding to the second arc segment. This setting ensures that the air inlet area is large enough and the air inlet resistance is smaller, which is beneficial to increasing the air inlet volume, thereby ensuring the oil fume suction effect of the integrated range hood. That is, it can efficiently handle kitchen oil fume, keep the kitchen air fresh, and effectively reduce noise, improving the user experience.

[0017] According to the above grille structure of the present application, it may also have the following additional technical features:

[0018] In some embodiments, optionally, in the longitudinal section of the flow guiding rib, at least one of the two outer contour lines of the connecting section is a third arc segment.

[0019] In this embodiment, the structure of the flow guiding rib is further defined.

[0020] Specifically, in the longitudinal section of the flow guiding rib, the outer contour lines on both sides of the connecting section are both third arc segments. The connecting section smoothly transitions between the windward section and the leeward section.

[0021] It can be understood that in the longitudinal section of the flow guiding rib, the number of the outer contour lines of the connecting section is two. The outer contour line on one side of the connecting section is a third arc segment. Or, the outer contour line on the other side of the connecting section is a third arc segment. Or, the outer contour lines on both sides of the connecting section are both third arc segments.

[0022] Optionally, both the first arc segment and the second arc segment are tangent to the third arc segment. That is, the first arc segment is tangent to the third arc segment, and the second arc segment is tangent to the third arc segment.

[0023] The windward section, the connecting section, and the leeward section cooperate to ensure the smoothness of the outer shape of the flow guiding rib, so as to play a role in changing the flow path of the air flow, and can produce an effective flow-around drag reduction effect, which is beneficial to reducing the operating noise of the integrated range hood.

[0024] In some embodiments, optionally, the distance h1 from the center of the circle corresponding to the first arc segment to the center of the circle corresponding to the second arc segment and the height h0 of the frame from the windward side to the leeward side satisfy: 0.876 ≤ h1 / h0 ≤ 1.071.

[0025] In this embodiment, the matching structure of the frame and the flow guiding rib is further defined.

[0026] Specifically, the distance from the center of the circle corresponding to the first arc segment to the center of the circle corresponding to the second arc segment is denoted as h1. Along the windward side to the leeward side of the frame, the height of the frame is denoted as h0. It can also be said that along the windward side to the leeward side of the frame, the frame has a first end face and a second end face, and the distance from the first end face to the second end face is denoted as h0.

[0027] Among them, the ratio of h1 to h0 satisfies: 0.876 ≤ h1 / h0 ≤ 1.071.

[0028] This setting can ensure that when the air flow passes through the flow guiding rib, the flow guiding rib has sufficient guiding length for the air flow, and can balance reducing the resistance of the high-speed air flow and ensuring the flow-around effect.

[0029] If h1 / h0 < 0.876, then the guiding effect of the flow guiding rib on the air flow is poor. When the air flow passes through the flow guiding rib, the grille structure will still vibrate strongly, and thus the noise during the operation of the integrated range hood is still large.

[0030] If h1 / h0 > 1.071, then the resistance of the flow guiding rib to the air flow is large, the consumption of the air volume is large, and the air intake volume will be reduced.

[0031] In some embodiments, optionally, the height h0 of the frame in the windward side to leeward side direction and the radius R0 corresponding to the first arc segment satisfy: R0 < h0.

[0032] In this embodiment, the matching structure of the frame and the flow guiding ribs is further defined.

[0033] Specifically, along the windward side to leeward side of the frame, the height of the frame is denoted as h0. That is to say, along the windward side to leeward side of the frame, the frame has a first end face and a second end face, and the distance from the first end face to the second end face is denoted as h0. The radius corresponding to the first arc segment is denoted as R0.

[0034] Among them, the relationship between R0 and h0 satisfies: R0 < h0.

[0035] That is to say, the radius R0 corresponding to the first arc segment is less than the height h0 of the frame in the windward side to leeward side direction.

[0036] This setting can ensure that when the air flow passes through the flow guiding ribs, the area of the frontal collision between the air flow and the flow guiding ribs is small, reducing the resistance to the air flow, ensuring the air intake volume. At the same time, this structural setting also facilitates the manufacture and demolding of the grille structure, with the advantages of low processing difficulty, high production efficiency and high qualified product rate.

[0037] If R0 is greater than or equal to h0, then the resistance to the air flow is large, the air intake resistance is even greater, which will reduce the air intake volume, thereby reducing the oil fume suction effect of the integrated range hood.

[0038] In some embodiments, optionally, R0 and h0 satisfy: 0.357 ≤ R0 / h0 ≤ 0.437.

[0039] In this embodiment, the relationship between the height h0 of the frame in the windward side to leeward side direction and the radius R0 corresponding to the first arc segment is further defined to satisfy 0.357 ≤ R0 / h0 ≤ 0.437.

[0040] This setting takes into account both the air intake resistance and the manufacturability of the product.

[0041] If R0 / h0 < 0.357, then the demolding difficulty of the grille structure is high, the demolding effect is poor, and the windward section of the flow guiding ribs is easily damaged, which will reduce the manufacturability of the grille structure.

[0042] If R0 / h0 > 0.437, then the area of the frontal collision between the air flow and the flow guiding ribs is large, which will increase the resistance to the air flow, resulting in a reduction in the air intake volume. At the same time, this setting makes the grille structure still vibrate strongly when the air flow passes through the grille structure, and the effect of suppressing the abnormal sound of the grille structure is poor.

[0043] In some embodiments, optionally, the height h0 of the frame in the windward side to leeward side direction and the radius R1 corresponding to the third arc segment satisfy: h0 < R1.

[0044] In this embodiment, the cooperation structure of the frame and the flow guiding rib is further defined.

[0045] Specifically, along the windward side to leeward side of the frame, the height of the frame is denoted as h0. That is to say, along the windward side to leeward side of the frame, the frame has a first end face and a second end face, and the distance from the first end face to the second end face is denoted as h0. The radius corresponding to the third arc segment is denoted as R1.

[0046] Among them, the relationship between R1 and h0 satisfies: h0 < R1.

[0047] That is to say, the radius R1 corresponding to the third arc segment is greater than the height h0 of the frame in the windward side to leeward side direction.

[0048] This setting takes into account both the air inlet resistance and the guiding effect on the air flow.

[0049] If R1 ≤ h0, then the length of the part of the flow guiding rib for guiding the air flow is short, the guiding effect on the air flow is poor, and the vibration damping effect of the whole machine is poor.

[0050] In some embodiments, optionally, R1 and h0 satisfy: 2.561 ≤ R1 / h0 ≤ 3.129.

[0051] In this embodiment, the relationship between the height h0 of the frame in the windward side to leeward side direction and the radius R1 corresponding to the third arc segment is further defined to satisfy 2.561 ≤ R1 / h0 ≤ 3.129.

[0052] This setting takes into account both the air inlet resistance and the guiding effect on the air flow.

[0053] If R1 / h0 < 2.561, then the length of the part of the flow guiding rib for guiding the air flow is short, the guiding effect on the air flow is poor, and the vibration damping effect of the whole machine is poor.

[0054] If R1 / h0 > 3.129, then the resistance when the air flow passes through the flow guiding rib is large, that is, the air inlet resistance is increased. In this way, the consumption of the air volume is large, and the air inlet volume will be reduced.

[0055] In some embodiments, optionally, the height h0 of the frame in the windward side to leeward side direction and the radius R2 corresponding to the second arc segment satisfy: R2 < h0.

[0056] In this embodiment, the cooperation structure of the frame and the flow guiding rib is further defined.

[0057] Specifically, along the windward side to the leeward side of the frame, the height of the frame is denoted as h0. That is to say, along the windward side to the leeward side of the frame, the frame has a first end face and a second end face, and the distance from the first end face to the second end face is denoted as h0. The radius corresponding to the second arc segment is denoted as R2.

[0058] Among them, the relationship between R2 and h0 satisfies: R2 < h0.

[0059] That is to say, the radius R2 corresponding to the second arc segment is less than the height h0 of the frame in the direction from the windward side to the leeward side.

[0060] This setting takes into account both the air intake resistance and the guiding effect on the air flow.

[0061] If R2 ≥ h0, then the resistance of the air flow passing through the guide ribs is relatively large, that is, the air intake resistance is increased. In this way, the consumption of the air volume is relatively large, and the air intake volume will be reduced.

[0062] In some embodiments, optionally, R2 and h0 satisfy: 0.729 ≤ R2 / h0 ≤ 0.892.

[0063] In this embodiment, the relationship between the height h0 of the frame in the direction from the windward side to the leeward side and the radius R2 corresponding to the second arc segment is further defined to satisfy 0.729 ≤ R2 / h0 ≤ 0.892.

[0064] This setting takes into account both the air intake resistance and the guiding effect on the air flow.

[0065] If R2 / h0 < 0.729, then the volume of the part of the guide ribs for guiding the air flow is relatively small, the guiding effect on the air flow is poor, and the vibration reduction effect of the whole machine is poor.

[0066] If R2 / h0 > 0.892, then the resistance of the air flow passing through the guide ribs is relatively large, that is, the air intake resistance is increased. In this way, the consumption of the air volume is relatively large, and the air intake volume will be reduced.

[0067] It can be understood that when the air flow passes through the guide ribs, frictional resistance and flow-around will be generated to reduce the vortices formed by the air flow.

[0068] In some embodiments, optionally, the number of the guide ribs is multiple, and the multiple guide ribs are arranged at intervals along the direction perpendicular to the first side face to the second side face.

[0069] In this embodiment, the number and arrangement position of the guide ribs are further defined.

[0070] Specifically, the number of the guide ribs is multiple. Along the direction perpendicular to the first side face to the second side face, the multiple guide ribs are arranged at intervals. Any two adjacent guide ribs and the inner peripheral surface of the frame enclose a smoking port, and the guide rib at the end and the inner peripheral surface of the frame enclose a smoking port.

[0071] This setting enables the air flow entering through the grille structure to be effectively deflected by the flow guiding ribs. While ensuring the manufacturability of the product, it can reduce the resistance to high-speed air flow. The air flow does not directly impact the grille structure but undergoes a flow-around under the action of the shape of the flow guiding ribs. In this way, the impact energy of the air flow is reduced, significantly reducing the noise during the operation of the integrated range hood and enhancing the product's performance and market competitiveness.

[0072] In some embodiments, optionally, along the windward side to the leeward side of the frame, the frame has a first end face and a second end face arranged oppositely. The windward section of the flow guiding rib is located between the first end face and the second end face, or the vertex of the first arc segment lies on the plane where the first end face is located.

[0073] In this embodiment, the mating structure of the frame and the flow guiding rib is further defined.

[0074] Specifically, the frame has a first end face and a second end face. Along the windward side to the leeward side of the frame, the first end face and the second end face are opposite and arranged at intervals.

[0075] The windward section of the flow guiding rib is located between the first end face and the second end face, or the vertex of the first arc segment lies on the plane where the first end face is located.

[0076] It can be understood that when the container is placed on the integrated range hood, the windward section of the flow guiding rib faces the container. If a part of the windward section protrudes from the first end face, the flow guiding rib will lift the container upward, causing the container to tilt and unable to be stably placed.

[0077] In the second aspect of the present application, an integrated range hood is proposed, including: the grille structure as in the first aspect.

[0078] The integrated range hood provided by the present application includes the grille structure as in the first aspect. Since the integrated range hood includes the grille structure as in the first aspect, it thus has all the beneficial effects of the above grille structure and will not be elaborated one by one here.

[0079] In some embodiments, optionally, the integrated range hood further includes: a panel with an opening, and the grille structure is located at the opening; a housing connected to the panel, with a flue arranged inside the housing, and the flue is communicated with a smoke suction port; an oil separator arranged in the flue, and the oil separator is used to separate the oil in the oil fume flowing in through the smoke suction port.

[0080] In this embodiment, the structure of the integrated range hood is further defined.

[0081] Specifically, the integrated range hood further includes a panel, a housing, and an oil separator.

[0082] The panel is provided with an opening, and the grille structure is provided at the opening. Specifically, the panel is provided at the top of the stove body of the integrated stove, and its function is to support the heated container, and at the same time provide the user with an operation interface and display menu. The panel is an important part of the integrated stove. It is not only the interface for the user to interact with the integrated stove, but also the key to the appearance and function display of the integrated stove. The panel is usually made of durable and easy-to-clean materials, usually glass or metal, to ensure its long-term use and facilitate daily maintenance.

[0083] An opening is provided on the panel, which serves to connect the inside and the outside, making it convenient for the inhaled oil smoke to enter the interior of the integrated stove from the opening for processing.

[0084] The grille structure is located at the opening, and the panel has the function of fixing and supporting the grille structure. The solidity of the grille structure can ensure that it remains stable during long-term use and is not easily deformed or damaged. At the same time, the grille structure also serves as a bridge connecting the panel and the internal structure of the integrated stove, ensuring the stability and safety of the overall structure.

[0085] The shell is the main structural part of the integrated stove and is connected to the panel. It not only provides protection and support, but also ensures the cleanliness and beauty of the interior of the integrated stove. The flue is the passage inside the integrated stove. The first end of the flue is connected to the smoke inlet, so that the oil smoke can enter the flue smoothly.

[0086] The grease separator is arranged in the flue. Optionally, the grease separator is arranged opposite to the grille structure. The main function of the grease separator is to separate the grease in the oil smoke flowing into the smoke inlet. When the oil smoke passes through the flue, the grease separator can effectively capture and separate the grease particles to prevent them from entering the exhaust system or adhering to the inside of the integrated stove. This can not only reduce the pollution of the kitchen environment by the oil smoke, but also keep the integrated stove clean and stable in performance.

[0087] In some embodiments, optionally, the integrated stove further includes: a range hood assembly, which is connected to the side of the shell facing away from the panel, and the range hood assembly is connected to the flue, and the range hood assembly is used to extract oil smoke through the smoke intake port and the flue; a filter element, which is arranged in the shell, and the filter element is located between the grease separator and the range hood assembly.

[0088] In this embodiment, the structure of the integrated stove is further defined.

[0089] Specifically, the integrated stove also includes a range hood assembly and a filter element.

[0090] The hood assembly is connected to the side of the housing away from the panel, and is connected to the flue. The hood assembly is used to extract oil smoke through the smoke inlet and the flue. During the cooking process, oil smoke is an inevitable product, and the strong suction force of the hood assembly can quickly and effectively suck the oil smoke, thereby keeping the kitchen air fresh and hygienic.

[0091] The filter element is disposed inside the housing, and the filter element is located between the grease separator and the range hood assembly. After the smoke flow passes through the filter element, the filter element can filter out the smell of the cooking fumes.

[0092] Optionally, the filter element includes activated carbon, carbon mesh or carbon block.

[0093] Optionally, a volute, an impeller, a motor and a shock pad are provided inside the range hood assembly. An air inlet is provided on the range hood assembly, and the air inlet is communicated with the flue. The volute is disposed obliquely below the air inlet. The function of the volute is to wrap the impeller and the motor, so that the impeller and the motor can form a sufficiently large gas flow, thereby forming a sufficiently large negative pressure to produce the effect of sucking cooking fumes. The volute is provided with a volute air inlet and a volute air outlet. The volute air outlet is docked with the smoke pipe. The cooking fumes enter the volute from the volute air inlet, and then are discharged from the volute air outlet to the smoke pipe. The volute air inlet, the impeller and the motor are all installed upward and opposite to the air inlet, which can avoid an S-shaped turn in the air duct. Therefore, the air duct resistance can be reduced, the energy efficiency can be improved, and the smoking effect can be improved.

[0094] When the motor starts to work, it drives the impeller to rotate, generating a strong air flow, causing a negative pressure near the smoke inlet, so that the cooking fumes generated during cooking enter the grease separator from the smoke inlet, filter out most of the grease, then enter the filter element from the grease separator, and after the smell is filtered out by the filter element, it then enters the inside of the volute downward from the volute air inlet, passes through the impeller, and finally is discharged into the smoke pipe from the volute air outlet. Such a cycle is continuous to achieve the suction and purification of the cooking fumes.

[0095] Optionally, the shock pad is located between the motor and the inner surface of the range hood assembly, and this setting is beneficial to reducing vibration noise.

Detailed implementation manners

[0111] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0112] In the following description, numerous specific details are set forth to provide a thorough understanding of the present application. However, the present application may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0113] The grille structure 10 and the integrated cooking stove 40 of some embodiments of the present application will be described below with reference to Figures 1 to 11 Figures.

[0114] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 5 Figures, a grille structure 10 according to some embodiments of the present application is for an integrated cooking stove 40. The grille structure 10 includes a frame 100 and flow guiding ribs 200.

[0115] The inner peripheral surface 110 of the frame 100 includes a first side surface 112 and a second side surface 114 that are oppositely arranged.

[0116] The flow guiding ribs 200 are connected between the first side surface 112 and the second side surface 114.

[0117] The flow guiding ribs 200 and the inner peripheral surface 110 of the frame 100 enclose a plurality of smoking ports 300.

[0118] Along the windward side 140 to the leeward side 150 of the frame 100, the flow guiding ribs 200 include a windward section 210, a leeward section 220, and a connecting section 230.

[0119] The connecting section 230 is connected between the windward section 210 and the leeward section 220.

[0120] In the longitudinal section 240 of the flow guiding rib, the outer contour line of the windward section 210 is a first arc segment 212, and the outer contour line of the leeward section 220 is a second arc segment 222. The radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222.

[0121] Along the windward section 210 to the leeward section 220, the distance between the outer contour lines on both sides of the connecting section 230 gradually increases.

[0122] Wherein, the longitudinal section 240 of the flow guiding rib is perpendicular to the direction from the first side surface 112 to the second side surface 114.

[0123] A grille structure 10 provided by the present application includes a frame 100 and flow guiding ribs 200.

[0124] The frame 100 has an inner peripheral surface 110. The inner peripheral surface 110 includes a first side surface 112 and a second side surface 114. The first side surface 112 and the second side surface 114 are opposite and spaced apart.

[0125] The flow guide rib 200 is connected to the inner peripheral surface 110 of the frame 100. Specifically, the flow guide rib 200 is connected to the first side surface 112 and the flow guide rib 200 is connected to the second side surface 114. That is to say, the flow guide rib 200 is connected between the first side surface 112 and the second side surface 114.

[0126] It can be understood that the flow guide rib 200 and the inner peripheral surface 110 of the frame 100 enclose a plurality of smoking ports 300.

[0127] Furthermore, the frame 100 has a windward side 140 and a leeward side 150 which are oppositely arranged, and the flue gas flows from the windward side 140 to the leeward side 150. The flow guide rib 200 includes a windward section 210, a leeward section 220 and a connecting section 230. The connecting section 230 is connected to the windward section 210 and the connecting section 230 is connected to the leeward section 220. That is to say, the connecting section 230 is connected between the windward section 210 and the leeward section 220.

[0128] Taking a cross-section of the flow guide rib 200 in a direction perpendicular to the first side surface 112 to the second side surface 114, in the longitudinal section 240 of the flow guide rib, the outer contour line of the windward section 210 is the first arc segment 212, and the outer contour line of the leeward section 220 is the second arc segment 222. The radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222. And along the windward section 210 to the leeward section 220, the distance between the outer contour lines on both sides of the connecting section 230 gradually increases. It can be seen from this that the outer surface of the windward section 210 is an arc surface, the outer surface of the leeward section 220 is an arc surface, and the size of the outer surface of the windward section 210 is different from the size of the outer surface of the leeward section 220.

[0129] By reasonably setting the cooperation structure of the windward section 210, the connecting section 230 and the leeward section 220, while ensuring the manufacturability of the product, the resistance to high-speed airflow can be reduced. The airflow will not directly impact the grille structure 10, but will flow around under the action of the outer shape of the flow guide rib 200. In this way, the impact energy of the airflow is reduced, which will greatly reduce the noise during the operation of the integrated stove 40 and improve the use performance and market competitiveness of the product.

[0130] It can be understood that the outer surface of the windward section 210 is an arc surface. This setting enables the windward section 210 to not only reduce the resistance to high-speed airflow, but also facilitate the demolding of the grille structure 10, and has processing feasibility and convenience.

[0131] It can be understood that the outer surface of the leeward section 220 is an arc surface, and along the windward section 210 to the leeward section 220, the distance between the outer contour lines on both sides of the connection section 230 gradually increases. The leeward section 220 and the connection section 230 cooperate to change the flow path of the air flow, which can produce an effective flow-around drag reduction effect and is beneficial to reducing the operating noise of the integrated range hood 40. More specifically, the connection section 230 and the leeward section 220 cooperate to play a role in guiding the flow. When the air flow passes through the uniformly changing connection section 230 and the leeward section 220, the vortices of the air flow can be reduced, and further reduce the noise when the integrated range hood 40 works.

[0132] It can be understood that the radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222. This setting ensures that the air inlet area is large enough and the air inlet resistance is smaller, which is beneficial to increasing the air inlet volume, thereby ensuring the oil fume suction effect of the integrated range hood 40. That is, it can efficiently handle kitchen oil fume, keep the kitchen air fresh, and effectively reduce noise, improving the user experience.

[0133] In some embodiments, optionally, in the longitudinal section 240 of the flow guiding rib, at least one of the outer contour lines on both sides of the connection section 230 is a third arc segment 232.

[0134] Both the first arc segment 212 and the second arc segment 222 are tangent to the third arc segment 232.

[0135] In this embodiment, the structure of the flow guiding rib 200 is further defined.

[0136] Specifically, in the longitudinal section 240 of the flow guiding rib, the outer contour lines on both sides of the connection section 230 are both third arc segments 232. The connection section 230 smoothly transitions between the windward section 210 and the leeward section 220.

[0137] It can be understood that in the longitudinal section 240 of the flow guiding rib, the number of the outer contour lines of the connection section 230 is two. The outer contour line on one side of the connection section 230 is a third arc segment 232. Or, the outer contour line on the other side of the connection section 230 is a third arc segment 232. Or, the outer contour lines on both sides of the connection section 230 are both third arc segments 232.

[0138] Among them, both the first arc segment 212 and the second arc segment 222 are tangent to the third arc segment 232. That is, the first arc segment 212 is tangent to the third arc segment 232, and the second arc segment 222 is tangent to the third arc segment 232.

[0139] The windward section 210, the connection section 230 and the leeward section 220 cooperate to ensure the smoothness of the outer shape of the flow guiding rib 200, so as to change the flow path of the air flow, which can produce an effective flow-around drag reduction effect and is beneficial to reducing the operating noise of the integrated range hood 40.

[0140] In some other embodiments, in the longitudinal section 240 of the flow guiding rib, at least one of the outer contour lines on both sides of the connecting section 230 is a straight line segment.

[0141] In some other embodiments, in the longitudinal section 240 of the flow guiding rib, at least one of the outer contour lines on both sides of the connecting section 230 includes a straight line segment and an arc segment.

[0142] In some embodiments, optionally, as Figure 4 shown, the distance h1 from the center of the circle corresponding to the first arc segment 212 to the center of the circle corresponding to the second arc segment 222 and the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 satisfy: 0.876 ≤ h1 / h0 ≤ 1.071.

[0143] In this embodiment, the mating structure of the frame 100 and the flow guiding rib 200 is further defined.

[0144] Specifically, the distance from the center of the circle corresponding to the first arc segment 212 to the center of the circle corresponding to the second arc segment 222 is denoted as h1. Along the windward side 140 to the leeward side 150 of the frame 100, the height of the frame 100 is denoted as h0. That is to say, along the windward side 140 to the leeward side 150 of the frame 100, the frame 100 has a first end face 120 and a second end face 130, and the distance from the first end face 120 to the second end face 130 is denoted as h0.

[0145] Among them, the ratio of h1 to h0 satisfies: 0.876 ≤ h1 / h0 ≤ 1.071.

[0146] This setting can ensure that when the air flow passes through the flow guiding rib 200, the flow guiding rib 200 has a sufficient guiding length for the air flow, and can take into account reducing the resistance of the high-speed air flow and ensuring the effect of the circumferential flow.

[0147] If h1 / h0 < 0.876, then the guiding effect of the flow guiding rib 200 on the air flow is poor. When the air flow passes through the flow guiding rib 200, the grille structure 10 will still vibrate strongly, and thus, the noise during the operation of the integrated range hood 40 is still relatively large.

[0148] If h1 / h0 > 1.071, then the resistance of the flow guiding rib 200 to the air flow is large, the consumption of the air volume is large, and the air intake volume will be reduced.

[0149] Optionally, h1 / h0 = 0.9, h1 / h0 = 0.95, h1 / h0 = 0.98, and h1 / h0 = 1, etc., which are not listed one by one here.

[0150] In some embodiments, optionally, as Figure 4As shown, the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R0 corresponding to the first arc segment 212 satisfy: R0 < h0.

[0151] In this embodiment, the matching structure of the frame 100 and the flow guiding rib 200 is further defined.

[0152] Specifically, along the windward side 140 to the leeward side 150 of the frame 100, the height of the frame 100 is denoted as h0. That is to say, along the windward side 140 to the leeward side 150 of the frame 100, the frame 100 has a first end face 120 and a second end face 130, and the distance from the first end face 120 to the second end face 130 is denoted as h0. The radius corresponding to the first arc segment 212 is denoted as R0.

[0153] Among them, the relationship between R0 and h0 satisfies: R0 < h0.

[0154] That is to say, the radius R0 corresponding to the first arc segment 212 is less than the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150.

[0155] This setting can ensure that when the air flow passes through the flow guiding rib 200, the area of the region where the air flow collides with the front of the flow guiding rib 200 is small, reducing the resistance to the air flow, ensuring the air intake volume. At the same time, this structural setting also facilitates the manufacture and demolding of the grille structure 10, with the advantages of low processing difficulty, high production efficiency, and high qualified product rate.

[0156] If R0 is greater than or equal to h0, then the resistance to the air flow is large, and the air intake resistance is even greater, which will reduce the air intake volume, thereby reducing the oil fume suction effect of the integrated range hood 40.

[0157] In some embodiments, optionally, R0 and h0 satisfy: 0.357 ≤ R0 / h0 ≤ 0.437.

[0158] In this embodiment, the relationship between the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R0 corresponding to the first arc segment 212 is further defined to satisfy 0.357 ≤ R0 / h0 ≤ 0.437.

[0159] This setting takes into account both the air intake resistance and the manufacturability of the product.

[0160] If R0 / h0 < 0.357, then the demolding difficulty of the grille structure 10 is high, the demolding effect is poor, and the windward section 210 of the flow guiding rib 200 is easily damaged, which will reduce the manufacturability of the grille structure 10.

[0161] If R0 / h0 > 0.437, then the area of the region where the air flow collides with the front of the flow guiding rib 200 is large, which will increase the resistance to the air flow and result in a decrease in the air intake volume. At the same time, this setting causes the grille structure 10 to still vibrate strongly when the air flow passes through the grille structure 10, and the effect of suppressing the abnormal sound of the grille structure 10 is poor.

[0162] Optionally, R0 / h0 = 0.38, R0 / h0 = 0.4, R0 / h0 = 0.41, R0 / h0 = 0.42, and R0 / h0 = 0.43, etc., which are not listed one by one here.

[0163] In some embodiments, optionally, as Figure 4 shown, the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R1 corresponding to the third arc segment 232 satisfy: h0 < R1.

[0164] In this embodiment, the matching structure of the frame 100 and the flow guiding rib 200 is further defined.

[0165] Specifically, along the windward side 140 to the leeward side 150 of the frame 100, the height of the frame 100 is denoted as h0. That is to say, along the windward side 140 to the leeward side 150 of the frame 100, the frame 100 has a first end face 120 and a second end face 130, and the distance from the first end face 120 to the second end face 130 is denoted as h0. The radius corresponding to the third arc segment 232 is denoted as R1.

[0166] Among them, the relationship between R1 and h0 satisfies: h0 < R1.

[0167] That is to say, the radius R1 corresponding to the third arc segment 232 is greater than the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150.

[0168] This setting takes into account both the air intake resistance and the guiding effect on the air flow.

[0169] If R1 ≤ h0, then the length of the part of the flow guiding rib 200 used to guide the air flow is short, the guiding effect on the air flow is poor, and the vibration reduction effect of the whole machine is poor.

[0170] In some embodiments, optionally, R1 and h0 satisfy: 2.561 ≤ R1 / h0 ≤ 3.129.

[0171] In this embodiment, the relationship between the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R1 corresponding to the third arc segment 232 is further defined to satisfy 2.561 ≤ R1 / h0 ≤ 3.129.

[0172] This setting takes into account both the air intake resistance and the guiding effect on the air flow.

[0173] If R1 / h0 < 2.561, then the length of the part of the air guiding rib 200 for guiding the air flow is short, the air guiding effect on the air flow is poor, and the vibration damping effect of the whole machine is poor.

[0174] If R1 / h0 > 3.129, then the resistance of the air flow when flowing through the air guiding rib 200 is large, that is, the air inlet resistance is increased. In this way, the consumption of the air volume is large, and the air inlet volume will be reduced.

[0175] Optionally, R1 / h0 = 2.6, R1 / h0 = 2.7, R1 / h0 = 2.8, R1 / h0 = 2.9, and R1 / h0 = 3, etc., which are not listed one by one here.

[0176] In some embodiments, optionally, as Figure 4 shown, the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R2 corresponding to the second arc segment 222 satisfy: R2 < h0.

[0177] In this embodiment, the matching structure of the frame 100 and the air guiding rib 200 is further defined.

[0178] Specifically, along the windward side 140 to the leeward side 150 of the frame 100, the height of the frame 100 is denoted as h0. It can also be said that along the windward side 140 to the leeward side 150 of the frame 100, the frame 100 has a first end face 120 and a second end face 130, and the distance from the first end face 120 to the second end face 130 is denoted as h0. The radius corresponding to the second arc segment 222 is denoted as R2.

[0179] Among them, the relationship between R2 and h0 satisfies: R2 < h0.

[0180] That is to say, the radius R2 corresponding to the second arc segment 222 is less than the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150.

[0181] This setting takes into account both the air inlet resistance and the guiding effect on the air flow.

[0182] If R2 ≥ h0, then the resistance of the air flow when flowing through the air guiding rib 200 is large, that is, the air inlet resistance is increased. In this way, the consumption of the air volume is large, and the air inlet volume will be reduced.

[0183] In some embodiments, optionally, R2 and h0 satisfy: 0.729 ≤ R2 / h0 ≤ 0.892.

[0184] In this embodiment, the relationship between the height h0 of the frame 100 in the direction from the windward side 140 to the leeward side 150 and the radius R2 corresponding to the second arc segment 222 is further defined so that it satisfies 0.729 ≤ R2 / h0 ≤ 0.892.

[0185] This setting takes into account both the air intake resistance and the guiding effect on the air flow.

[0186] If R2 / h0 < 0.729, then the volume of the part of the flow guiding rib 200 for guiding the air flow is small, the guiding effect on the air flow is poor, and the vibration reduction effect of the whole machine is poor.

[0187] If R2 / h0 > 0.892, then the resistance of the air flow passing through the flow guiding rib 200 is large, that is, the air intake resistance is increased. In this way, the consumption of the air volume is large, and the air intake volume will be reduced.

[0188] Optionally, R2 / h0 = 0.73, R2 / h0 = 0.74, R2 / h0 = 0.75, R2 / h0 = 0.78, R2 / h0 = 0.8, R2 / h0 = 0.82, R2 / h0 = 0.84, R2 / h0 = 0.85, and R2 / h0 = 0.88, etc., which are not listed one by one here.

[0189] It can be understood that when the air flow passes through the flow guiding rib 200, frictional resistance and flow around will occur to reduce the vortices formed by the air flow.

[0190] In some embodiments, optionally, as Figure 1 and Figure 2 shown, the number of the flow guiding ribs 200 is multiple.

[0191] The multiple flow guiding ribs 200 are arranged at intervals in a direction perpendicular to the first side surface 112 to the second side surface 114.

[0192] In this embodiment, the number and arrangement position of the flow guiding ribs 200 are further defined.

[0193] Specifically, the number of the flow guiding ribs 200 is multiple. Along the direction perpendicular to the first side surface 112 to the second side surface 114, the multiple flow guiding ribs 200 are arranged at intervals. Any two adjacent flow guiding ribs 200 and the inner peripheral surface 110 of the frame 100 enclose a smoking port 300, and the flow guiding rib 200 at the end and the inner peripheral surface 110 of the frame 100 enclose a smoking port 300.

[0194] This setting enables the air flow entering from the grille structure 10 to be effectively guided by the flow guiding ribs 200. While ensuring the manufacturability of the product, the resistance to the high-speed air flow can be reduced. The air flow will not directly impact the grille structure 10, but will flow around under the action of the shape of the flow guiding ribs 200. In this way, the impact energy of the air flow is reduced, and the noise during the operation of the integrated stove 40 will be greatly reduced, improving the use performance and market competitiveness of the product.

[0195] In some embodiments, optionally, as Figure 3As shown, along the windward side 140 to the leeward side 150 of the frame 100 , the frame 100 has a first end surface 120 and a second end surface 130 that are oppositely disposed.

[0196] The windward section 210 of the guide rib 200 is located between the first end surface 120 and the second end surface 130 .

[0197] Alternatively, the vertex of the first arc segment 212 is located on the plane where the first end surface 120 is located.

[0198] In this embodiment, the matching structure of the frame 100 and the guide rib 200 is further defined.

[0199] Specifically, the frame 100 has a first end surface 120 and a second end surface 130. Along the windward side 140 to the leeward side 150 of the frame 100, the first end surface 120 and the second end surface 130 are arranged opposite to each other and spaced apart.

[0200] The windward section 210 of the guide rib 200 is located between the first end surface 120 and the second end surface 130 , or the vertex of the first arc segment 212 is located on the plane where the first end surface 120 is located. The vertex of the first arc segment 212 is set away from the outer contour line of the connecting section 230 .

[0201] It is understandable that when the container is placed on the integrated stove 40, the windward section 210 of the guide rib 200 faces the container. If a portion of the windward section 210 protrudes out of the first end surface 120, the guide rib 200 will lift the container upward, causing the container to tilt and unable to be placed stably.

[0202] Optionally, the leeward section 220 is located between the first end surface 120 and the second end surface 130 .

[0203] Optionally, the vertex of the second arc segment 222 is located on the plane where the second end surface 130 is located. The vertex of the second arc segment 222 is arranged away from the outer contour line of the connecting segment 230 .

[0204] Optionally, at least a portion of the leeward segment 220 protrudes from the second end surface 130 .

[0205] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, an integrated stove 40 according to some other embodiments of the present application includes: a grille structure 10 as in any of the above embodiments.

[0206] The integrated stove 40 provided in the present application includes the grille structure 10 of any of the above-mentioned embodiments.

[0207] The grille structure 10 includes a frame 100 and flow guiding ribs 200.

[0208] The frame 100 has an inner peripheral surface 110, and the inner peripheral surface 110 includes a first side surface 112 and a second side surface 114. The first side surface 112 and the second side surface 114 are opposite and arranged at intervals.

[0209] The flow guiding ribs 200 are connected to the inner peripheral surface 110 of the frame 100. Specifically, the flow guiding ribs 200 are connected to the first side surface 112, and the flow guiding ribs 200 are connected to the second side surface 114. That is to say, the flow guiding ribs 200 are connected between the first side surface 112 and the second side surface 114.

[0210] It can be understood that the flow guiding ribs 200 and the inner peripheral surface 110 of the frame 100 enclose a plurality of smoking ports 300.

[0211] Furthermore, the frame 100 has an upwind side 140 and a downwind side 150 which are oppositely arranged, and the flue gas flows from the upwind side 140 to the downwind side 150. The flow guiding ribs 200 include an upwind section 210, a downwind section 220 and a connecting section 230. The connecting section 230 is connected to the upwind section 210, and the connecting section 230 is connected to the downwind section 220. That is to say, the connecting section 230 is connected between the upwind section 210 and the downwind section 220.

[0212] Taking a cross-section of the flow guiding ribs 200 in a direction perpendicular to the first side surface 112 to the second side surface 114, in the longitudinal section 240 of the flow guiding ribs, the outer contour line of the upwind section 210 is a first arc segment 212, and the outer contour line of the downwind section 220 is a second arc segment 222. The radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222. And along the upwind section 210 to the downwind section 220, the distance between the outer contour lines on both sides of the connecting section 230 gradually increases. It can be seen from this that the outer surface of the upwind section 210 is an arc surface, the outer surface of the downwind section 220 is an arc surface, and the size of the outer surface of the upwind section 210 is different from the size of the outer surface of the downwind section 220.

[0213] By reasonably setting the cooperation structure of the upwind section 210, the connecting section 230 and the downwind section 220, while ensuring the manufacturability of the product, the resistance to high-speed airflow can be reduced. The airflow will not directly impact the grille structure 10, but will flow around under the action of the outer shape of the flow guiding ribs 200. In this way, the impact energy of the airflow is reduced, which will greatly reduce the noise during the operation of the integrated range hood 40 and improve the use performance and market competitiveness of the product.

[0214] It can be understood that the outer surface of the upwind section 210 is an arc surface. This setting enables the upwind section 210 to not only reduce the resistance to high-speed airflow, but also facilitate the demolding of the grille structure 10, having processing feasibility and convenience.

[0215] It can be understood that the outer surface of the leeward section 220 is an arc surface, and along the windward section 210 to the leeward section 220, the distance between the outer contour lines on both sides of the connecting section 230 gradually increases. The leeward section 220 and the connecting section 230 cooperate to change the flow path of the air flow, which can produce an effective flow-around drag reduction effect and is beneficial to reducing the operating noise of the integrated stove 40. More specifically, the connecting section 230 and the leeward section 220 cooperate to play a role in guiding the flow. When the air flow passes through the uniformly changing connecting section 230 and leeward section 220, the vortices of the air flow can be reduced, and further the noise during the operation of the integrated stove 40 can be reduced.

[0216] It can be understood that the radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222. This setting ensures that the air inlet area is large enough and the air inlet resistance is smaller, which is beneficial to increasing the air inlet volume, thereby ensuring the oil fume suction effect of the integrated stove 40. That is, it can efficiently handle kitchen oil fume, keep the kitchen air fresh, and effectively reduce noise, improving the user experience.

[0217] In some embodiments, optionally, as Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, the integrated stove 40 further includes a panel 400, a housing 500 and an oil separator 600.

[0218] An opening 410 is provided on the panel 400, and the grille structure 10 is located at the opening 410.

[0219] The housing 500 is connected to the panel 400.

[0220] A flue 510 is provided inside the housing 500.

[0221] The flue 510 is communicated with the smoke suction port 300.

[0222] The oil separator 600 is arranged in the flue 510, and the oil separator 600 is used to separate the oil in the oil fume flowing in through the smoke suction port 300.

[0223] In this embodiment, the structure of the integrated stove 40 is further defined.

[0224] Specifically, the integrated stove 40 further includes a panel 400, a housing 500 and an oil separator 600.

[0225] An opening 410 is provided on the panel 400, and the grille structure 10 is disposed at the opening 410. Specifically, the panel 400 is arranged at the uppermost part of the stove body of the integrated stove 40, which serves to support the heated container and at the same time provides an operation interface and a display menu for the user. The panel 400 is an important component of the integrated stove 40. It is not only the interface for the user to interact with the integrated stove 40 but also the key to demonstrating the appearance and functions of the integrated stove 40. The panel 400 is usually made of durable and easy-to-clean materials, usually glass or metal, to ensure its long-term use and facilitate daily maintenance.

[0226] Optionally, the integrated stove 40 further includes an electromagnetic heating element for heating a container placed on the panel 400.

[0227] An opening 410 is provided on the panel 400. The opening 410 on the panel 400 plays a role in connecting the inside and the outside, facilitating the inhaled cooking fumes to enter the interior of the integrated stove 40 through the opening 410 for treatment.

[0228] The grille structure 10 is arranged at the opening 410. The panel 400 functions to fix and support the grille structure 10. The firmness of the grille structure 10 can ensure its stability during long-term use, being not easily deformed or damaged. At the same time, the grille structure 10 also serves as a connecting bridge between the panel 400 and the internal structure of the integrated stove 40, ensuring the stability and safety of the overall structure.

[0229] The housing 500, as the main structural part of the integrated stove 40, is connected to the panel 400, providing not only protection and support but also ensuring the neatness and beauty inside the integrated stove 40. The flue 510, as a passage inside the integrated stove 40, has its first end communicating with the smoke inlet, enabling the cooking fumes to smoothly enter the flue 510.

[0230] The grease separator 600 is disposed inside the flue 510. Optionally, the grease separator 600 is arranged opposite to the grille structure 10. The main function of the grease separator 600 is to separate the grease in the cooking fumes flowing in from the smoke inlet. During the process of the cooking fumes passing through the flue 510, the grease separator 600 can effectively capture and separate the grease particles, preventing them from entering the exhaust system or adhering to the interior of the integrated stove 40. This can not only reduce the pollution of the kitchen environment by the cooking fumes but also keep the integrated stove 40 clean and its performance stable.

[0231] In some embodiments, optionally, as Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, the integrated stove 40 further includes a smoke machine assembly 700 and a filter element 800.

[0232] The smoke machine assembly 700 is connected to the side of the housing 500 facing away from the panel 400, and the smoke machine assembly 700 communicates with the flue 510.

[0233] The smoke machine assembly 700 is used to extract cooking fumes through the smoke suction port 300 and the flue 510.

[0234] The filter element 800 is arranged inside the housing 500, and the filter element 800 is located between the grease separator 600 and the smoke machine assembly 700.

[0235] In this embodiment, the structure of the integrated stove 40 is further defined.

[0236] Specifically, the integrated stove 40 further includes a smoke machine assembly 700 and a filter element 800.

[0237] The smoke machine assembly 700 is connected to the side of the housing 500 facing away from the panel 400, and the smoke machine assembly 700 communicates with the flue 510. The smoke machine assembly 700 is used to extract cooking fumes through the smoke inlet and the flue 510. During the cooking process, cooking fumes are an inevitable product, and the strong suction of the smoke machine assembly 700 can quickly and effectively suck in the cooking fumes, thus keeping the kitchen air fresh and hygienic.

[0238] The filter element 800 is arranged inside the housing 500, and the filter element 800 is located between the grease separator 600 and the smoke machine assembly 700. After the smoke flows through the filter element 800, the filter element 800 can filter out the smell of the cooking fumes.

[0239] Optionally, the filter element 800 includes activated carbon, carbon mesh, carbon blocks, etc., which are not listed one by one here.

[0240] Optionally, a volute 710, an impeller 720, a motor 730 and a shock pad 740 are arranged inside the smoke machine assembly 700. An air inlet is arranged on the smoke machine assembly 700, and the air inlet communicates with the flue 510. The volute 710 is arranged obliquely below the air inlet. The function of the volute 710 is to wrap the impeller 720 and the motor 730, so that the impeller 720 and the motor 730 can form a large enough gas flow, thereby forming a large enough negative pressure to produce the effect of sucking cooking fumes. The volute 710 is provided with a volute 710 air inlet and a volute 710 air outlet. The volute 710 air outlet is docked with the smoke pipe. The cooking fumes enter the volute 710 from the volute 710 air inlet and are then discharged from the volute 710 air outlet to the smoke pipe. The volute 710 air inlet, the impeller 720 and the motor 730 are all installed upwards and opposite to the air inlet, which can avoid an S-shaped turn in the air duct. Therefore, the air duct resistance can be reduced, the energy efficiency can be improved, and the smoking effect can be improved.

[0241] When the motor 730 starts to work, it drives the impeller 720 to rotate, generating a strong air flow, creating a negative pressure near the smoke inlet, so that the cooking fumes are drawn into the grease separator 600 from the smoke inlet, most of the grease is filtered, then enters the filter element 800 from the grease separator 600, and after the smell is filtered by the filter element 800, it then enters the interior of the volute 710 from the air inlet of the volute 710 downward, passes through the impeller 720, and finally is discharged into the smoke pipe from the air outlet of the volute 710. Such a cycle continues continuously to achieve the suction and purification of cooking fumes.

[0242] Optionally, the shock pad 740 is located between the motor 730 and the inner surface of the range hood assembly 700, and this setting is beneficial to reducing vibration noise.

[0243] In this application, by reasonably setting the composition structure of the grille structure 10, the impact of the air flow on the grille structure 10 can be reduced. The flow guiding ribs 200 of the grille structure 10 can guide the air flow to flow around it, reducing the impact energy of the air flow on the grille structure 10. After the air flow passes through the grille structure 10 of this application, the vibration acceleration is reduced by 18%, the noise is reduced by 1.6 dB (which can effectively reduce the noise during the operation of the integrated range hood 40), and the air volume of the whole machine is increased by 6%.

[0244] In this application, the flow guiding rib 200 includes a windward section 210, a leeward section 220, and a connecting section 230, and the connecting section 230 is connected between the windward section 210 and the leeward section 220. In the longitudinal section 240 of the flow guiding rib, the outer contour line of the windward section 210 is the first arc segment 212, and the outer contour line of the leeward section 220 is the second arc segment 222. The radius corresponding to the first arc segment 212 is smaller than the radius corresponding to the second arc segment 222. Along the windward section 210 to the leeward section 220, the distance between the outer contour lines on both sides of the connecting section 230 gradually increases. The blockage of the grille structure 10 to the air flow becomes smaller, and the air flow impact weakens. Moreover, the flow guiding rib 200 can make the high-speed air flow flow around, and finally the vibration of the whole machine weakens and the abnormal noise disappears.

[0245] It can be understood that in the longitudinal section 240 of the flow guiding rib, the contour line of the flow guiding rib 200 is in a water droplet shape. The drag coefficient of the flow guiding rib 200 is relatively low.

[0246] Optionally, h0 is the height of the frame 100. Specifically, the height of the frame 100 in the direction from the windward side 140 to the leeward side 150 is h0. For example, h0 = 7.4 mm.

[0247] Optionally, the distance between the center corresponding to the first arc segment 212 and the center corresponding to the second arc segment 222 is h1. Among them, 0.876 ≤ h1 / h0 ≤ 1.071. For example, h1 = 7.2 mm.

[0248] Optionally, the radius corresponding to the first arc segment 212 is denoted as R0. Among them, 0.357 ≤ R0 / h0 ≤ 0.437. For example, R0 = 2.94 mm.

[0249] Optionally, the radius corresponding to the third arc segment 232 is denoted as R1. Among them, 2.561 ≤ R1 / h0 ≤ 3.129. For example, R1 = 21.05 mm.

[0250] Optionally, the radius corresponding to the second arc segment 222 is denoted as R2. Among them, 0.729 ≤ R2 / h0 ≤ 0.892. For example, R2 = 6.12 mm.

[0251] Among them, Figure 3 、 Figure 8 、 Figure 9 and Figure 11 the arrows in indicate the flow path of the air flow.
