Description

Technical Field

[0001] This utility model relates to the field of infrared burner technology, and in particular to infrared gas equipment. Background Technology

[0002] Infrared cooktops are gas cooktops that use the principle of infrared radiation for heating. They use an infrared radiant plate as the combustion radiator. The gas mixture, after being fully mixed with air, enters the tiny holes of the infrared radiant plate for combustion. The high temperature generated by combustion makes the entire infrared radiant plate glow brightly, and the heat energy is transferred to the cookware by infrared radiation. It has the advantages of high thermal efficiency and fast heating speed.

[0003] Infrared radiation panels are typically made of porous ceramic plates or metal fiber mesh, which have high manufacturing processes and costs. Exposed infrared radiation panels are easily damaged by collisions with cookware. To protect the infrared radiation panels, existing infrared cooktops will have a metal protective mesh installed above the infrared radiation panels. The metal protective mesh is installed on the burner head with screws.

[0004] Because infrared radiation panels require regular cleaning and maintenance, the tiny pores within them are prone to contamination or blockage after prolonged use, leading to reduced firepower and decreased combustion efficiency. In severe cases, this can result in gas leaks and safety hazards. Furthermore, the screw-mounted metal protective mesh is cumbersome to install and remove, requiring auxiliary tools and hindering the daily cleaning and maintenance of infrared cooktops.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] like Figures 1 to 3As shown, this embodiment of the invention first provides an infrared gas combustion device, which includes a burner head 2 and an infrared combustion plate 1. The burner head 2 is provided with a mixing chamber 23 containing a mixture of gas and air. The mixed gas enters the micropores of the infrared combustion plate 1 and burns to generate heat. The infrared combustion plate 1 is installed on top of the mixing chamber 23 and is configured to generate infrared radiation through gas combustion. The infrared combustion plate 1 includes, but is not limited to, a ceramic plate, and can also be a multi-layered metal mesh.

[0035] The infrared gas appliance also includes a protective component 3, which is connected to the burner head 2 and covers the infrared combustion plate 1. The protective component 3 provides protection for the infrared combustion plate 1, preventing damage caused by cookware bumping against it during daily use. The protective component 3 has heat conduction holes, allowing heat radiated by the infrared combustion plate 1 to be transferred to the cookware. The protective component 3 provides protection without affecting the performance of the infrared combustion plate 1; furthermore, it reduces external airflow disturbance to the flame of the infrared combustion plate 1.

[0036] One of the burner head 2 and the protective component 3 is provided with an installation groove 41, and the other is provided with a guide 42. The guide 42 is slidably disposed within the installation groove 41, allowing the protective component 3 to move and switch between a disassembled position and an installed position. When the protective component 3 is in the disassembled position, it can be detached from the burner head 2 for routine cleaning and maintenance of the infrared combustion plate 1. When the protective component 3 is in the installed position, it is constrained to the burner head 2, enabling its installation. The disassembly and installation of the protective component 3 are relatively convenient, requiring only movement between the disassembled and installed positions without the need for auxiliary disassembly tools, thus improving the convenience of daily cleaning and maintenance of the infrared gas equipment.

[0037] The burner head 2 has a side frame 21 surrounding the infrared combustion plate 1. The protective component 3 includes a protective net 31 covering the infrared combustion plate 1 and a side guard plate 32 surrounding and connected to the protective net 31. A mounting groove 41 is formed in one of the side frame 21 and the side guard plate 32, and a guide 42 is provided in the other. When the protective component 3 is in the installation position, the side frame 21 and the side guard plate 32 at least partially overlap along the height direction of the burner head 2. On the one hand, the overlap of the side frame 21 and the side guard plate 32 enables the guide 42 to slide within the mounting groove 41. On the other hand, the overlap of the side frame 21 and the side guard plate 32 also avoids side gaps, ensuring that the top and sides of the infrared combustion plate 1 are completely protected.

[0038] The protective net 31 has heat conduction holes and is made of iron-chromium-aluminum alloy wire woven into a mesh structure with a weaving density of 4 to 6 meshes. Iron-chromium-aluminum alloy wire has advantages such as high temperature resistance, oxidation resistance, and good structural strength. The protective net 31 provides good support and is suitable for high-temperature working environments. The protective net 31 has a secondary radiation effect, making the radiated heat from the infrared combustion plate 1 more uniform and improving the situation of less heat distribution at the edges and localized high temperatures in the center.

[0039] The mounting groove 41 is bent and extended, with an opening 411 at one end and a limiting part at the other end. The guide 42 is configured to slide between the opening 411 and the limiting part to allow the protective member 3 to rotate and rise and fall about the axis of the furnace head 2, thereby switching between the disassembly position and the installation position. Disassembly and installation can be achieved by the rotation and rising and falling action of the protective member 3.

[0040] The axial rotation and lifting action of the protective component 3 can be rotation followed by lifting, lifting followed by rotation, or lifting while rotating. The action of the protective component 3 is determined by the specific shape of the bending extension of the mounting groove 41.

[0041] For example, such as Figure 3 As shown, in one embodiment, the mounting groove 41 is formed on the side guard plate 32 of the protective member 3, and the guide member 42 is disposed on the side frame 21 of the burner head 2. In order to prevent the side guard plate 32 of the protective member 3 from scraping the infrared combustion plate 1 during the rotation and lifting process, the guide member 42 is disposed on the outside of the side frame 21 of the burner head 2, and the side guard plate 32 of the protective member 3 at the installation position surrounds the outer periphery of the side frame 21.

[0042] The opening 411 extends to the edge of the side guard plate 32. The other end of the mounting groove 41 away from the opening 411 has two groove walls arranged opposite each other along the height direction of the burner head 2 to form a limiting part. The guide 42 enters the mounting groove 41 through the opening 411 and can slide until it is engaged between the two groove walls. When the guide 42 is in the opening 411, the protective member 3 is in the disassembled position. While the protective member 3 rotates and rises and falls around the axis of the burner head 2, the guide 42 slides in the mounting groove 41 until the guide 42 slides until it is engaged between the two groove walls. The protective member 3 is in the installed position and is constrained on the burner head 2 to maintain positional stability during use.

[0043] The mounting groove 41 includes a vertical groove 413 and a horizontal groove 412 that are interconnected. The vertical groove 413 extends along the height direction of the burner head 2 and extends to the edge of the side guard plate 32 to form an opening 411. The horizontal groove 412 and the vertical groove 413 are arranged at an angle, and the horizontal groove 412 forms a limiting part. For example, as shown... Figure 4As shown, the horizontal groove 412 is set horizontally and forms a 90° angle with the vertical groove 413. When installing the protective component 3, the guide component 42 first enters the vertical groove 413 through the opening 411. The protective component 3 descends and approaches the infrared combustion plate 1. During this process, the guide component 42 slides along the vertical groove 413. Then, the protective component 3 is rotated, causing the guide component 42 to slide along the horizontal groove 412 until it slides to the end of the horizontal groove 412. The protective component 3 is then installed and is constrained to the burner head 2.

[0044] Of course, in other embodiments, the mounting groove 41 can also be formed on the side frame 21 of the furnace head 2, and the guide 42 can be set on the side guard plate 32 of the protective member 3. The horizontal groove 412 is located below the vertical groove 413, and the protective member 3 can be lowered and then rotated to achieve installation.

[0045] In another embodiment, the mounting groove 41 is formed on the side frame 21 of the burner head 2 and extends in a spiral bend along the circumference of the burner head 2. During the sliding of the guide member 42 along the mounting groove 41, the protective member 3 rotates around the axial direction of the burner head 2 and descends until the guide member 42 is constrained by the limiting part.

[0046] The width of the vertical groove 413 is greater than the width of the horizontal groove 412. For example, the width of the vertical groove 413 is 0.5 mm larger than the width of the horizontal groove 412. The slightly larger width of the vertical groove 413 facilitates the entry of the guide member 42 into the vertical groove 413; the slightly smaller width of the horizontal groove 412 can clamp the guide member 42, providing better constraint.

[0047] In one embodiment, the guide 42 uses a columnar pin, resulting in low sliding friction. The width of the transverse groove 412 is L1, and the outer diameter of the guide 42 is L2, where 0mm < L1 - L2 ≤ 3mm. When the difference between the two is within this range, the sliding of the guide 42 in the transverse groove 412 is not restricted and can be effectively constrained. Preferably, the width of the transverse groove 412 gradually decreases from one end connected to the vertical groove 413 to the other end. The guide 42 slides in the transverse groove 412 until it is locked, thus achieving the installation of the protective component 3. Figure 4 As shown in the figure, L1 is the width of the horizontal groove 412, L2 is the outer diameter of the guide 42; L3 is the width of the vertical groove 413, and L3 is slightly larger than L2; L4 is the length of the vertical groove 413, which is the height to which the protective component 3 descends during installation. The specific height can be set according to the size of the side guard plate 32 and the distance requirements between the protective net 31 and the infrared combustion plate 1. This embodiment does not impose specific limitations.

[0048] In one embodiment, two guide members 42 are provided, symmetrically arranged around the center of the furnace head 2, and two mounting grooves 41 are provided, such as... Figure 5As shown, the two mounting grooves 41 and the two guide members 42 correspond one-to-one. During the descent and rotation of the protective member 3, the two guide members 42 slide within their respective mounting grooves 41. The two guide members 42 provide two constraints on the protective member 3, resulting in better installation reliability.

[0049] The burner head 2 also includes an ignition needle 24 and a base 22, such as Figure 2 As shown, the ignition needle 24 is 7-shaped, comprising a body and an ignition end 241 connected to each other. One end of the body is located at the edge of the base 22, and the ignition end 241 is connected to the other end of the body. The infrared combustion plate 1 and the protective component 3 are connected to the base 22 from bottom to top, thus avoiding damage to the integrity of the infrared combustion plate 1. The infrared combustion plate 1 is made of a full-plane ceramic plate, which has better structural strength. The ignition end 241 of the ignition needle 24 extends above the protective component 3, and the protective component 3 has a recess 33 to avoid the ignition end 241. The protective component 3 needs to have a certain distance from the infrared combustion plate 1 to avoid affecting the combustion flame in the micropores on the protective component 3. At the same time, the distance between the ignition end 241 of the ignition needle 24 and the infrared combustion plate 1 should not be too large to avoid affecting the ignition efficiency. Through the recess 33 of the protective component 3, the ignition end 241 of the ignition needle 24 is located in the groove formed by the recess 33, thus avoiding the problem of height interference between the protective component 3 and the ignition end 241.

[0050] In one embodiment, the distance between the ignition end 241 and the infrared combustion plate 1 along the height direction of the burner head 2 is 3mm to 5mm. The distance between the ignition end 241 and the infrared combustion plate 1 can be, but is not limited to, 3mm, 3.5mm, 4mm, 5mm, etc.

[0051] Optionally, the recessed depth of the recessed portion 33 is 1.5mm to 2.5mm. Specifically, the recessed depth of the recessed portion 33 can be, but is not limited to, 1.5mm, 2mm, 2.5mm, etc.

[0052] In one embodiment, the side guard plate 32 is made of alloy plate, and the edge of the side guard plate 32 away from the protective mesh 31 has a coiled portion 34. The coiled portion 34 can improve the safety of the protective member 3 and reduce the risk of scratching from sharp edges. The coiled portion 34 is coiled outward to avoid interference with the side frame 21 of the furnace head 2. Moreover, the coiled portion 34 can increase the structural strength of the side guard plate 32 and reduce the risk of deformation of the side guard plate 32.

[0053] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0054] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
