Description

Technical Field

[0001] This utility model relates to the field of gas stoves, and in particular to a pot support heat shield. Background Technology

[0002] As gas stove performance improves, so does the load, causing some components to overheat during prolonged operation. This not only reduces energy efficiency stability but may also raise safety concerns for users. Besides supporting cookware, pot supports can also be improved to insulate against heat and reduce the rate of temperature rise of knobs. For example, installing heat-insulating components between the burner and the knob can effectively reduce the temperature rise of the knob and control panel by blocking high-temperature heat source transfer to the knob.

[0003] Existing technologies mainly block heat radiation from the burner center by setting a heat baffle on the pot support. For example, Chinese patent document CN215808644U discloses a magnetic heat baffle. By setting a magnetic component on the heat baffle and magnetically connecting it to the metal support of the pot support, the heat baffle is fixed on the pot support and located between the burner and the knob. This solves the problem of the knob overheating due to the combustion flame, which affects the safety of operation. However, the baffle in this solution covers the side of the pot support, resulting in insufficient secondary air supply, reduced combustion efficiency, and hindered flue gas diffusion. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect in the prior art where the pot support baffle blocks the external air from supplementing the oxygen required for combustion, thus affecting the thermal efficiency of combustion and flue gas, and to provide a pot support heat baffle.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A heat shield for a pot support includes a baffle body for connecting to the pot support and shielding at least part of the combustion flame; the baffle body is provided with an air inlet channel, the diameter of which gradually narrows along the direction close to the combustion flame.

[0007] In this design, a heat baffle is installed between the burner and the knob, with the baffle body directly connected to the pot support. This baffle protects against the radiant heat generated during burner operation, reducing the knob's heating rate and simplifying the stove's structure for easier disassembly and cleaning. Furthermore, an air inlet channel is incorporated into the baffle body, with its diameter gradually narrowing towards the flame. This effectively isolates high-temperature radiation while ensuring sufficient secondary air supply. The gradually narrowing air inlet channel also creates a strong suction force on the side of the heat baffle closest to the burner, facilitating faster inward airflow and reducing the area of ​​the high-temperature radiation window, thus weakening the radiation of heat to the surrounding area and lowering the work surface temperature.

[0008] Preferably, the area near the knob on the baffle body is a closed region.

[0009] In this design, no air inlet channel is provided near the knob on the baffle body. This area is made of enclosed baffle body material. By enclosing the area of ​​the baffle body near the knob, the knob can be prevented from directly receiving heat radiation from the air inlet channel at the corresponding position of the baffle body. This effectively prevents the knob from being directly heated by the combustion flame, thereby reducing the knob temperature.

[0010] Preferably, the baffle body has a through hole, and a flange surrounds the through hole on the side of the baffle body near the combustion flame, the through hole and the flange forming the air intake channel.

[0011] Preferably, the air inlet channel has a frustum-shaped cross-section in the vertical direction.

[0012] Preferably, the air inlet channel is a strip-shaped hole.

[0013] Preferably, the number of air inlet channels is two or more; along the vertical and horizontal directions, the multiple air inlet channels are arranged in multiple rows and columns on the baffle body.

[0014] In this scheme, by setting two or more air inlet channels and arranging multiple rows and columns of air inlet channels along the vertical and horizontal directions, secondary air is supplied to the burner in a comprehensive and uniform manner.

[0015] Preferably, the heat shield of the pot support is further provided with a fixing part, which is connected to the baffle body, and there is a gap between the fixing part and the plane where the baffle body is located, for insertion into the pot support.

[0016] Preferably, the gap between the fixing part and the baffle body is not greater than the width of the support ring of the pot support.

[0017] In this solution, by controlling the gap between the fixing part and the baffle body to be no greater than the support ring of the pot support, an interference fit is achieved between the fixing part and the support ring of the pot support, ensuring that the heat baffle can be firmly connected to the pot support and improving the reliability of the heat baffle installation.

[0018] Preferably, the fixing part is an elastic buckle.

[0019] Preferably, the baffle body further includes a first heat-blocking plate and a second heat-blocking plate, the first heat-blocking plate and the second heat-blocking plate are connected and set at a 90-degree angle; both the first heat-blocking plate and the second heat-blocking plate are provided with the air inlet channel.

[0020] Preferably, at the position of the first heat shield and the second heat shield near the knob, the first heat shield and the second heat shield are closed regions at least in the middle area in the vertical direction.

[0021] Preferably, the top of the heat shield of the pot support is not higher than the top of the pot support.

[0022] In this solution, by controlling the top of the heat shield of the pot support to not be higher than the top of the pot support, it helps the flue gas to diffuse and prevents the heat shield from being directly burned by the flame for a long time, which would cause the heat shield to heat up too quickly.

[0023] The positive and progressive effects of this utility model are as follows:

[0024] By installing a heat baffle between the burner and the knob, with the baffle body directly connected to the pot support, the radiant heat generated during burner operation is contained, reducing the knob's heating rate. This also simplifies the stove's structure, making it easier to disassemble and clean. Furthermore, by incorporating an air intake channel on the baffle body, with the channel's diameter gradually narrowing towards the combustion flame, it effectively isolates high-temperature radiation while ensuring sufficient secondary air supply. The gradually narrowing air intake channel also creates a strong suction force on the side of the heat baffle closest to the burner, facilitating the accelerated inward flow of external air to replenish the air supply. Simultaneously, it reduces the area of ​​the high-temperature radiation window, weakening the radiation of high-temperature heat to the surrounding area and lowering the work surface temperature.

[0043] Pot support 3 Detailed Implementation

[0044] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0045] like Figures 1-5 As shown, this embodiment provides a pot support heat shield 001, which includes a baffle body 1 for connecting with the pot support 3 and shielding at least part of the combustion flame; the baffle body 1 is provided with an air inlet channel 11, and the diameter of the air inlet channel 11 gradually narrows along the direction close to the combustion flame.

[0046] In other embodiments, an additional enclosure structure can be set to enclose the area of ​​the baffle body 1 near the knob to block the direct heat radiation from the combustion flame to the knob, effectively preventing the knob from being directly heated by the combustion flame, thereby reducing the knob temperature. This will not be elaborated further here.

[0047] like Figures 1-7As shown, in this embodiment, the pot support heat shield 001 is further provided with a fixing part 2, which is connected to the baffle body 1. A gap 21 exists between the fixing part 2 and the plane of the baffle body 1 for insertion into the pot support 3. The gap 21 between the fixing part 2 and the baffle body 1 is not greater than the width of the support ring of the pot support 3. The fixing part 2 is preferably an elastic buckle, which is formed by bending a metal sheet. This metal sheet has good elasticity and ductility. The bent portion forms a gap 21 with the plane of the baffle body 1, which is used to engage the support ring of the pot support 3. The fixing part 2 is also integrally formed with the baffle body 1. Part 2 is integrally set with the baffle body 1, which reduces the installation difficulty and structural complexity of the pot support heat shield 001 and improves the firmness of the connection between the pot support heat shield 001 and the pot support 3. When connecting, the metal piece of the fixing part 2 can be manually pried open so that the gap 21 of the fixing part 2 can be expanded to accommodate the support ring of the pot support 3. The fixing part 2 is then placed in the corresponding position of the pot support 3 to be installed. The fixing part 2 is then released so that the fixing part 2 can be snapped onto the support ring of the pot support 3 by utilizing the elasticity of the material itself. One end of the bent part is connected to the baffle body 1, and the other end is a free end. In addition, the fixing part 2 is also integrally set with the baffle body 1.

[0048] In other embodiments, the structure of the fixing part 2 can also be other methods that can achieve a stable connection between the baffle body 1 and the pot support 3 and facilitate disassembly and assembly. The fixing part 2 can also be separated from the baffle body 1. The fixing part 2 can be connected to the baffle body 1 through a detachable connection structure, which will not be described in detail here.

[0049] like Figures 1-3 As shown, in this embodiment, the air inlet channel 11 is a strip-shaped hole, and there are two or more air inlet channels 11. Along the vertical and horizontal directions, multiple air inlet channels 11 are arranged in multiple rows and columns on the baffle body 1.

[0050] like Figures 2-3 As shown, the baffle body 1 also includes a first heat-blocking plate 12 and a second heat-blocking plate 13. The first heat-blocking plate 12 and the second heat-blocking plate 13 are connected and set at a 90-degree angle. The baffle body 1 is in a closed area 14 near the knob. In this embodiment, the air inlet channel 11 is arranged sequentially on the first heat-blocking plate 12 and the second heat-blocking plate 13 along the horizontal direction A and the horizontal direction B, respectively. The air inlet channel 11 is also arranged sequentially on the first heat-blocking plate 12 and the second heat-blocking plate 13 along the vertical direction C (e.g., ...). Figure 2As indicated by the arrows, the long and short sides of the air inlet channel 11 are arranged in the same direction as the first heat baffle 12 and the second heat baffle 13. The row and column spacing of the air inlet channel 11 array is consistent. The first heat baffle 12 and the second heat baffle 13 are closest to the knob, and the row and column of that position are closed with through holes 111. In this embodiment, the first heat baffle 12 and the second heat baffle 13 are provided to meet the heat resistance requirements of the square pot support 3. In commonly used stoves, the knob is usually located in the middle of the dual burners, closest to one corner of the square pot support 3. Therefore, in this embodiment, the shape of the baffle body 1 is adjusted to better fit the stove. Both the first heat baffle 12 and the second heat baffle 13 are provided with air inlet channels 11. The air inlet channels 11 are evenly distributed on the first heat baffle 12 and the second heat baffle 13 to achieve a uniform air supply effect.

[0051] In other embodiments, the baffle body 1 may be composed of a single or other number of heat-insulating plates to adapt to different stove sizes and structures. The shape of the baffle body 1 may also be arc-shaped, straight, or other shapes that can be adapted to the corresponding pot support 3. The setting of the air inlet channel 11 may also be adapted to the cooking needs, which will not be described in detail here.

[0052] like Figures 4-5 As shown, in this embodiment, a through hole 111 is formed on the baffle body 1, and on the side of the baffle body 1 closest to the combustion flame (e.g., Figure 6 As shown by the arrow), a flange 112 surrounds the through hole 111. The through hole 111 and the flange 112 form an air intake channel 11. The flange 112 is positioned in a direction close to the combustion flame (as shown by the arrow). Figure 6 (As indicated by the arrow) gradually narrows, with the flange 112 close to the side of the burning flame (as shown). Figure 6 (As indicated by the arrow) The diameter of the end face is smaller than the diameter of the through hole 111, and the cross-sectional shape of the air inlet channel 11 in the vertical direction is a frustum shape.

[0053] In other embodiments, the cross-sectional shape of the air inlet duct 11 in the vertical direction may also be other along the burner direction (e.g., Figure 6 The shape of the constriction (as indicated by the arrow) is designed so that the heat baffle faces the side of the burner (as shown by the arrow). Figure 6 (As indicated by the arrow) This creates a strong ejector attraction, thereby accelerating the replenishment of secondary air and improving combustion efficiency, which will not be elaborated further here.

[0054] In other embodiments, the air intake channel 11 can also be formed by methods such as thickening the material of the baffle body 1 and opening a through hole 111 on the baffle body 1, and forming the hole wall of the through hole 111 by the baffle body 1 material, without the need to set an additional flange 112, which will not be described in detail here.

[0055] like Figures 6-7 As shown, the top of the heat shield 001 of the pot support is not higher than the top of the pot support 3. This setting is for the diffusion of smoke and prevents the flame from directly burning the heat shield, causing the heat shield to heat up too quickly and affecting the heat dissipation of the stove.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
