Abstract
Description
Technical Field
[0001] This application belongs to the technical field of cooking appliances, and more specifically, relates to a heating component and a cooking device. Background Technology
[0002] Currently, the heating element in cooking equipment mainly consists of a burner head and a first radiant plate. The burner head introduces gas and generates a flame, while the first radiant plate is installed above the burner head to shield the flame and heat it to a red-hot state through the flame, thereby emitting infrared heat radiation to cook the food above.
[0003] However, during the process of heating the first radiant plate by the burner head, the area of the first radiant plate directly above the burner head receives more heat, while other areas receive less heat. This results in poor heating uniformity of the first radiant plate as a whole, which in turn affects the cooking effect of infrared heat radiation. Utility Model Content
[0004] The purpose of this application is to provide a heating component and a cooking device to solve the problem of poor infrared thermal radiation effect caused by uneven heating of the first radiant plate in the prior art.
[0005] To achieve the above objectives, in a first aspect, this application provides a heating assembly, including a burner head and a radiating component disposed above the burner head, wherein the burner head is used to heat the radiating component to cause the radiating component to generate infrared thermal radiation;
[0006] The burner head includes a heating tube and at least one flame deflector disposed on the outer wall of the heating tube. Flame holes are provided on the periphery of the heating tube and are located below the flame deflector. The flame deflector is gradually inclined upward relative to the horizontal plane from the direction away from the heating tube, and a flame channel penetrating in the vertical direction is provided on the side of the flame deflector facing the heating tube.
[0007] In some embodiments of the first aspect, the fire baffle is provided with at least one connecting portion at one end facing the heating tube, the connecting portion being connected to the outer wall surface of the heating tube, so that the fire baffle is spaced apart from the heating tube and forms at least one flame channel.
[0008] In some embodiments of the first aspect, there are multiple flame holes, which are symmetrically arranged in two groups around the heating tube. The multiple flame holes in each group are spaced apart along the extension direction of the heating tube. There are two fire baffles, which extend in a direction parallel to the extension direction of the heating tube. Each fire baffle is correspondingly arranged above the multiple flame holes in each group.
[0009] In some embodiments of the first aspect, the radiating component includes a first radiating plate and a second radiating plate disposed above the first radiating plate, the second radiating plate having radiating holes.
[0010] In some embodiments of the first aspect, the first radiant plate includes a plate body and a radiant mesh disposed on the plate body; the plate body has a hollow portion, and the radiant mesh covers the hollow portion; the projection of the burner head on the horizontal plane falls within the projection of the radiant mesh on the horizontal plane.
[0011] In some embodiments of the first aspect, the projection shape of the second radiant plate on a vertical plane perpendicular to the extension direction of the heating tube is an flared shape that gradually expands from top to bottom, and the first radiant plate is mounted on the bottom of the second radiant plate.
[0012] In some embodiments of the first aspect, a slide is provided at the bottom of the second radiant plate, the extension direction of the slide is parallel to the extension direction of the heating tube, and the first radiant plate is slidably connected in the slide; at least one extension end of the slide is provided with an opening so that the first radiant plate can slide out of the slide.
[0013] In some embodiments of the first aspect, the bottom end of the second radiating plate is provided with a downwardly extending first support portion, the first support portion is provided with a second support portion extending toward the first radiating plate, and the second radiating plate, the first support portion and the second support portion are arranged to form the slide.
[0014] In some embodiments of the first aspect, the projection position of the radiation aperture on the horizontal plane avoids the projection of the heating tube on the horizontal plane.
[0015] Secondly, this application also provides a cooking apparatus, including a furnace body and the heating components described in the first aspect and any embodiment thereof, wherein the furnace head and the radiating components are arranged sequentially from bottom to top on the furnace body.
[0016] The beneficial effects of the heating component and cooking device provided in this application are as follows: Compared with the prior art, the burner head includes a heating tube and a baffle plate. The baffle plate is located above the flame hole of the heating tube and has at least one flame channel. After gas is introduced into the heating tube and a flame is generated, the flame is ejected through the flame hole. Part of the flame can extend upward directly through the flame channel, while another part of the flame rises through the bottom inclined surface of the baffle plate. This optimizes the flow path of the flame, expands the contact area between the flame and the radiating component, enhances the heat exchange efficiency between the flame and the radiating component, makes the radiating component more evenly heated, and improves the effect of the radiating component in generating infrared heat radiation.

[0038] Reference Figure 1 This application provides a heating component 10, which includes a furnace head 100 and a radiating component 200. The radiating component 200 is disposed above the furnace head 100, and the furnace head 100 is used to heat the radiating component 200 so that the radiating component 200 generates infrared thermal radiation.
[0039] Reference Figure 2The heating component 10 provided in this application embodiment is applied in a cooking device. The cooking device may include a furnace body 20, a storage tray 30, and the aforementioned heating component 10. Both the heating component 10 and the storage tray 30 are disposed in the furnace body 20. The burner head 100, the radiant element 200, and the storage tray 30 are arranged sequentially from bottom to top. The storage tray 30 is used to place the food to be cooked. The burner head 100 is used to introduce combustible materials such as gas and generate a flame. The flame heats the radiant element 200 above, causing the radiant element 200 to generate infrared heat radiation. The infrared heat radiation is used to cook the food placed in the storage tray 30, thereby avoiding problems such as food carbonization caused by direct contact between the flame and the food.
[0040] Reference Figure 3 , Figure 4 and Figure 5 The burner head 100 includes a heating tube 110 and at least one flame deflector 120 disposed on the outer wall of the heating tube 110. Flame holes 1101 are provided on the periphery of the heating tube 110 and are located below the flame deflector 120. The flame deflector 120 is gradually inclined upward relative to the horizontal plane from the direction away from the heating tube 110, and a flame channel 1201 that runs through the vertical direction is provided on the side of the flame deflector 120 facing the heating tube 110.
[0041] The heating tube 110 is a hollow tube for introducing combustible materials such as gas. Its shape can be cylindrical or other suitable shapes to adapt to different heating needs. In this embodiment, the heating tube 110 is a cylindrical tube. Both ends of the heating tube 110 are respectively provided with a connector 111 and a mounting part 112. The connector 111 is used to connect to a gas source. The shape of the mounting part 112 is adapted to the inner wall of the furnace body 20, and a mounting hole 1121 is provided so that the mounting part 112 can be connected to the furnace body 20 of the cooking device using fasteners, thus fixing the position of the heating tube 110 inside the furnace body 20.
[0042] Flame holes 1101 are formed on the peripheral sidewall of the heating tube 110 to allow the flame burning inside the heating tube 110 to be ejected. The shape of the flame holes 1101 can be circular, elliptical, or other suitable shapes to adapt to different flame ejection requirements. In this embodiment, multiple flame holes 1101 are formed on the peripheral side of the heating tube 110. The multiple flame holes 1101 are divided into two groups and respectively arranged on opposite sides of the heating tube 110 in the horizontal direction. The multiple flame holes 1101 in each group are evenly spaced along the extension direction of the heating tube 110 so that the flame is evenly ejected from both sides of the heating tube 110.
[0043] The flame deflector 120 can be made of stainless steel or other metallic materials or heat-resistant non-metallic materials such as ceramics. The shape and number of flame deflectors 120 can be adapted to the distribution of flame holes 1101 on the heating tube 110. In this embodiment, multiple flame holes 1101 are opened on both sides of the heating tube 110. There are two flame deflectors 120, which are symmetrically connected to both sides of the heating tube 110. The flame deflectors 120 are rectangular in shape, and their extension direction is parallel to the extension direction of the heating tube 110, so as to block the flames emitted from the flame holes 1101 on the same side of the heating tube 110, thereby dispersing and guiding the flames emitted from the flame holes 1101 on both sides.
[0044] A flame channel 1201 is formed on the side of the baffle plate 120 facing the heating tube 110. The extension direction of the flame channel 1201 can be parallel to the extension direction of the heating tube 110, and the flame channel 1201 is vertically continuous, allowing part of the flame ejected from the flame hole 1101 to extend upward through the flame channel 1201. The shape of the flame channel 1201 can be elongated, elliptical, or other suitable shapes to adapt to different flame flow requirements. The flame channel 1201 can be formed by forming a through hole in the baffle plate 120, or the baffle plate 120 can be spaced apart from the heating tube 110, forming a flame channel 1201 between the baffle plate 120 and the heating tube 110. In some embodiments, at least one connecting portion 121 can be provided at the end of the baffle plate 120 facing the heating tube 110, and the connecting portion 121 is connected to the outer wall surface of the heating tube 110, so that the baffle plate 120 and the heating tube 110 are spaced apart and at least one flame channel 1201 is formed.
[0045] Reference Figure 6 The connecting portion 121 protrudes from the side of the fire baffle 120 facing the heating tube 110, and the extending direction of the connecting portion 121 is perpendicular to the fire baffle 120. The connecting portion 121 can be connected to the outer wall of the heating tube 110 by welding, connecting bolts or other fasteners, so as to fix the fire baffle 120 to the heating tube 110, and to form a flame channel 1201 by spacing the position of the fire baffle 120 without the connecting portion 121 from the outer wall of the heating tube 110. In this embodiment, each fire baffle 120 is provided with three connecting portions 121, and the three connecting portions 121 are arranged at intervals along the extending direction of the fire baffle 120, so as to form two flame channels 1201 on the side of each fire baffle 120 facing the heating tube 110.
[0046] Combined Figure 3As shown, by setting inclined baffle plates 120 on both sides of the heating tube 110, part of the flames ejected from both sides of the heating tube 110 extend upward through the flame channel 1201 and the other part extends and ejects in the direction away from the heating tube 110 along the surface of the inclined baffle plate 120. This changes the flame ejection path, increases the range of flames ejected from the burner head 100, makes the upper radiating component 200 more uniformly heated, and produces better infrared thermal radiation.
[0047] Reference Figure 7 The radiant component 200 may include a first radiant plate 210 and a second radiant plate 220 connected above the first radiant plate 210. The second radiant plate 220 has a radiant hole 2201. The first radiant plate 210 is positioned close to the burner head 100 to shield the flame emitted from the burner head 100 and reaches a red-hot state through the heating of the flame, thereby emitting infrared heat radiation. The second radiant plate 220 shields the first radiant plate 210 from exposure, preventing the flame emitted from the burner head 100 and the red-hot first radiant plate 210 from being exposed, providing a certain degree of safety protection. The infrared heat radiation emitted by the first radiant plate 210 can be transmitted to the food above through the radiant hole 2201, achieving heating and cooking of the food.
[0048] Reference Figure 8 In some embodiments, the first radiant plate 210 may include a plate body 211 and a radiant mesh 212. In some embodiments of the first aspect, the first radiant plate 210 includes a plate body 211 and a radiant mesh 212 disposed on the plate body 211; the plate body 211 has a hollow portion 2111, and the radiant mesh 212 covers the hollow portion 2111; the projection of the burner head 100 on the horizontal plane falls into the projection of the radiant mesh 212 on the horizontal plane.
[0049] The plate 211 can be circular, rectangular, or similar in shape. The size of the plate 211 is adapted to the length of the heating tube 110 below, so as to completely cover the entire heating tube 110. In this embodiment, the plate 211 is a rectangular flat plate, and all four sides of the plate 211 are bent downwards to form peripheral sidewalls, improving the structural strength of the plate 211. The shape of the cutout 2111 can be circular, elliptical, strip-shaped, or other suitable shapes. The cutout 2111 is located at the center of the plate 211, and its size matches the size of the heating tube 110 and is positioned directly opposite the heating tube 110. In this embodiment, the cutout 2111 is a rectangular through hole.
[0050] The radial mesh 212 has a mesh structure and can be formed using processes such as weaving or laser cutting. The shape of the pores in the radial mesh 212 can be circular, elliptical, rectangular, or other polygonal shapes. (Refer to...) Figure 9In this embodiment, the pores in the radiating mesh 212 are rhomboid in shape. The shape of the radiating mesh 212 matches the shape of the hollow portion 2111 to cover the entire hollow portion 2111. In this embodiment, the radiating mesh 212 is rectangular in shape, and the size of the radiating mesh 212 is larger than the size of the hollow area to completely cover the entire hollow area.
[0051] The flame ejected from the heating tube 110 is dispersed and guided by the fire baffles 120 on both sides to uniformly heat the first radiation plate 210. The multiple pores in the radiation mesh 212 can increase the heating area, allowing the heat of the flame to be transferred to the entire radiation mesh 212 more quickly, enabling the first radiation plate 210 to heat up to a red-hot state quickly and accelerate the generation of infrared thermal radiation.
[0052] In some embodiments, combined with Figure 3 and Figure 7 As shown, the projection shape of the second radiation plate 220 on the vertical plane perpendicular to the extension direction of the heating tube 110 is an flared shape that gradually expands from top to bottom, and the first radiation plate 210 is installed at the bottom of the second radiation plate 220.
[0053] The projection shape of the second radiant plate 220 on the vertical plane can be a U-shape, V-shape, inverted trapezoid, or other shapes that gradually increase in size from top to bottom with the opening facing downwards. On the one hand, this allows a heat transfer cavity to be formed between the second radiant plate 220 and the first radiant plate 210, which is beneficial for the upward transfer of infrared heat radiation. On the other hand, it allows oil droplets and other substances generated during cooking to drip down along the top surface of the second radiant plate 220 to both sides of the burner head 100, preventing them from accumulating on the surface of the second radiant plate 220 or dripping onto the heating tube 110 and affecting the combustion of the flame.
[0054] In this embodiment, the second radiating plate 220 is composed of two symmetrical inclined plates, so that the projection shape of the second radiating plate 220 on the vertical plane is a V-shaped structure with the opening facing downwards. The two inclined plates can be integrally formed, or they can be processed separately and then connected and fixed by welding or other methods to form the second radiating plate 220.
[0055] Each inclined plate has multiple radiation holes 2201, which can be circular, elliptical, rectangular, or other polygonal, to accommodate different heat transfer requirements. In this embodiment, the radiation holes 2201 are strip-shaped, and their extension direction is parallel to the width direction of the inclined plate. Multiple radiation holes 2201 are spaced apart along the extension direction of the inclined plate to improve the uniformity of infrared heat radiation transfer.
[0056] Furthermore, the projection position of the radiant hole 2201 on the horizontal plane avoids the projection of the heating tube 110 on the horizontal plane. That is, no radiant hole 2201 is opened at the connection part 121 of the two inclined plates. In use, if the flame of the heating tube 110 burns too intensely, it will not directly spray out of the radiant hole 2201 vertically, which protects the food being cooked and the user, and improves safety during cooking.
[0057] Furthermore, a slide rail 2202 is provided at the bottom of the second radiant plate 220. The extension direction of the slide rail 2202 is parallel to the extension direction of the heating tube 110. The first radiant plate 210 is slidably connected within the slide rail 2202. At least one extension end of the slide rail 2202 is open, allowing the first radiant plate 210 to slide out of the slide rail 2202. By slidably connecting the first radiant plate 210 within the slide rail 2202, the first radiant plate 210 and the second radiant plate 220 can be connected as a single component for easy installation into the furnace body 20. Additionally, the first radiant plate 210 can slide out of the slide rail 2202, facilitating cleaning of the first radiant plate 210. (Refer to...) Figure 10 In this embodiment, the bottom end of the second radiating plate 220 is provided with a downwardly extending first support portion 221, and the first support portion 221 is provided with a second support portion 222 extending toward the first radiating plate 210. The second radiating plate 220, the first support portion 221 and the second support portion 222 surround to form a slide 2202.
[0058] Furthermore, refer to Figure 11 and Figure 12 One of the extended ends of the second support portion 222 may be provided with an upwardly protruding limiting portion 223 to block one of the openings of the slide rail 2202, thereby limiting the installation position of the first radiant plate 210 within the slide rail 2202. When the heating assembly 10 is installed in the cooking device, the opening end of the slide rail 2202 may face either the connection portion 121 of the heating tube 110 or the mounting portion 112 of the heating tube 110; this embodiment does not impose any restrictions on this.
[0059] In this embodiment, slides 2202 are provided on both sides of the bottom of the second radiating plate 220 to support the two sides of the first radiating plate 210 and improve the connection stability of the first radiating plate 210 and the second radiating plate 220.
[0060] Furthermore, the first radiant plate 210 and the second radiant plate 220 can also be installed separately within the oven body 20, facilitating individual disassembly, maintenance, or replacement of the first radiant plate 210 and the second radiant plate 220. Similarly, in this embodiment, the burner head 100 and the radiant component 200 are separately installed within the oven body 20, facilitating individual disassembly, maintenance, or replacement of either the burner head 100 or the radiant component 200. Of course, the burner head 100 and the radiant component 200 can also be connected as a whole via a connecting structure and then installed as a whole within the oven body 20 of the cooking appliance.
[0061] In summary, the heating assembly 10 provided in this application embodiment allows combustible materials such as gas to enter the heating tube 110 through the connector 111 and burn to generate a flame. The flame is ejected through the flame holes 1101 on the periphery of the heating tube 110 and is dispersed and guided by the flame deflector 120, enabling the flame to heat the radiant component 200 more evenly. The first radiant plate 210 in the radiant component 200 is composed of a plate body 211 and a radiant mesh 212, and can quickly heat up to a red-hot state under the heating of the flame, emitting infrared heat radiation. The second radiant plate 220 shields the first radiant plate 210 from direct contact between the flame and the food. At the same time, the infrared heat radiation emitted by the first radiant plate 210 can be transmitted to the food above through the radiation holes 2201 on the second radiant plate 220, improving safety during cooking.
[0062] Secondly, referring to Figure 2 This application also provides a cooking apparatus, including a heating component 10 and a furnace body 20 as described in the first aspect embodiment, wherein the heating component 10 is installed in the furnace body 20.
[0063] The cooking device can be an oven, grill, barbecue grill, or other device with heating and cooking functions. The oven body 20 provides installation space for the heating element 10, and its shape can be cuboid or other suitable shapes. When the cooking device is an oven, it may also include a shelf mounted on top of the heating element 10 for placing food. A certain gap can be formed between the shelf and the heating element 10 to facilitate heat transfer and food cooking. The shelf can be a baking pan, grill rack, grill, or other component capable of placing food, and its shape and size can be adapted based on cooking needs.
[0064] During use, the flame generated by the burner head 100 heats the radiating component 200 on the upper side. After being heated, the radiating component 200 emits infrared heat radiation, which passes through the food on the shelf, achieving uniform heating and cooking. Since the flame does not directly contact the food, the problem of food carbonization is avoided. At the same time, the infrared heat radiation heating method also makes the food heated more evenly, improving the cooking quality.
[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
