Description

Technical Field

[0001] This utility model relates to a pot support and a gas stove containing the pot support. Background Technology

[0002] Most gas stoves nowadays are equipped with pot supports to hold pots. As people pay more attention to energy conservation and environmental protection, pot supports are usually equipped with energy-concentrating baffles to prevent high-temperature flue gas from escaping. The structure of the energy-concentrating baffles improves the heat concentration effect, thereby improving the thermal efficiency of the gas stove.

[0003] Traditional pot holders typically have simple heat-concentrating baffles, but these are not effective at concentrating heat, resulting in low thermal efficiency of the gas stove. They are also not windproof, and the small flame can easily be blown away by the wind. On the other hand, some heat-concentrating baffles have complex structures and high manufacturing costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the problems of low thermal efficiency, inability to effectively concentrate heat, and easy wind damage caused by small flames in existing gas stoves, and to provide a pot support and a gas stove containing the pot support.

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

[0006] A pot support includes an energy-concentrating component and several foot pieces. Each foot piece includes a support portion for supporting the bottom of the pot, a recessed mounting portion, and a connecting portion for mounting a base plate, connected sequentially from top to bottom. The recessed mounting portion has a mounting groove recessed inward from the inner wall surface of the foot piece. The energy-concentrating component includes an outer retaining ring and an inner retaining ring. The outer retaining ring is disposed within the several mounting grooves so that the energy-concentrating component is mounted and connected to the several foot pieces. The outer surface of the outer retaining ring has a windproof groove that is recessed radially inward from the outer surface of the outer retaining ring along the energy-concentrating component. The top of the inner retaining ring is connected to the inner surface of the outer retaining ring, and the bottom of the inner retaining ring extends downward.

[0007] In this design, the aforementioned structural form is adopted. The support part supports the bottom of the pot, and the recessed mounting part has a mounting groove that is recessed inward from the inner wall of the foot piece. The connecting part is used to mount the chassis. The energy-concentrating component includes an outer baffle ring and an inner baffle ring. The outer baffle ring of the energy-concentrating component is connected to the mounting groove of the foot piece, so that the energy-concentrating component is mounted on several foot pieces. The outer side of the outer baffle ring has a windproof groove that is recessed inward from the outer side of the outer baffle ring along the radial direction of the energy-concentrating component. The inwardly recessed outer baffle ring can increase the shape resistance of the windward surface, reduce the incoming flow velocity, and achieve a significant windproof effect. The top of the inner baffle ring is connected to the inner side of the outer baffle ring, and the bottom of the inner baffle ring extends downward, thereby effectively preventing heat from diffusing downward and enhancing convective heat transfer with the bottom of the pot, thus increasing the energy-concentrating effect.

[0008] Preferably, the inner wall surface of the windproof groove is an arc surface.

[0009] In this scheme, the above-mentioned structural form is adopted. The inner wall surface of the windproof channel is a circular arc surface. The inwardly concave circular arc surface has a large resistance system at the Reynolds number, which can effectively prevent wind.

[0010] Preferably, the outer retaining ring is hemispherical in shape.

[0011] In this solution, the above-mentioned structural form is adopted. The outer baffle ring is hemispherical in shape. The windproof groove on the outer side of the outer baffle ring is recessed inward along the radial direction of the energy-concentrating component from the outer side of the outer baffle ring. The inner wall can be a hemispherical inner wall that is recessed inward, so that the drag coefficient is maximized and the windproof effect is most effective in reducing the incoming flow velocity.

[0012] Preferably, the foot piece has at least one retaining groove, which is recessed inward from the inner wall of the mounting groove, and the outer retaining ring is snapped into the retaining groove.

[0013] In this solution, the above-mentioned structural form is adopted, and the slotted connection between the outer retaining ring and the foot piece can fix the foot piece and the energy-concentrating component, making them difficult to move.

[0014] Preferably, there are two slots, and the upper and lower ends of the outer retaining ring are respectively snapped into the two slots.

[0015] In this solution, the above-mentioned structural form is adopted, and the number of slots is determined to be two. These two slots respectively snap-fit ​​the upper and lower ends of the outer retaining ring, so that the foot piece is fixedly connected to the energy-concentrating component in two places, resulting in stronger stability.

[0016] Preferably, the inner wall surface of the inner baffle ring has a flow guiding surface, which extends from top to bottom along a direction close to the center of the energy-concentrating component.

[0017] In this solution, the above-mentioned structural form is adopted. The inner wall surface of the inner baffle ring has a flow guiding surface. The flow guiding surface extends from top to bottom along the direction close to the center of the energy-concentrating component. After the flow guiding surface extends in the direction close to the center of the energy-concentrating component, it can prevent the heat of the energy-concentrating component from diffusing downward and block the loss of heat, resulting in better energy concentration effect.

[0018] Preferably, the guide surface is an arc surface.

[0019] Preferably, the inner retaining ring is shaped like a quarter-spherical shell; and / or, the top of the inner retaining ring is connected to the middle region of the inner side surface of the outer retaining ring.

[0020] Preferably, the inner retaining ring is welded to the outer retaining ring; and / or, the outer retaining ring is welded to the foot piece.

[0021] A gas stove, including the pot support as described above.

[0022] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain the preferred embodiments of this utility model.

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

[0024] This utility model discloses a pot support and a gas stove including the pot support. By setting an outer baffle ring on the pot support, with an inwardly recessed windproof groove on the outer side of the outer baffle ring, the shape resistance of the windward surface of the outer baffle ring is increased, thereby reducing the incoming airflow velocity and achieving a significant windproof effect. Furthermore, by setting an inner baffle ring on the pot support, heat is effectively prevented from diffusing downwards, and convective heat transfer with the bottom of the pot is enhanced, thereby increasing the energy concentration effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0050] This utility model provides a gas stove, which includes a pot support.

[0051] like Figures 1 to 6As shown, the pot support includes an energy-concentrating component 10 and several foot pieces 20. Each foot piece 20 includes a support portion 201 for supporting the bottom of the pot, a recessed mounting portion 203, and a connecting portion 205 for mounting the base plate, which are connected sequentially from top to bottom. The recessed mounting portion 203 has a mounting groove 2031 that is recessed inward from the inner wall of the foot piece 20. The energy-concentrating component 10 includes an outer retaining ring 11 and an inner retaining ring 12. The outer retaining ring 11 is disposed in the several mounting grooves 2031 so that the energy-concentrating component 10 is mounted and connected to the several foot pieces 20. The outer side of the outer retaining ring 11 has a windproof groove 111 that is recessed inward from the outer side of the outer retaining ring 11 along the radial direction of the energy-concentrating component 10. The top of the inner retaining ring 12 is connected to the inner side of the outer retaining ring 11, and the bottom of the inner retaining ring 12 extends downward.

[0052] Specifically, the pot support in this embodiment includes an energy-concentrating component 10 and several foot pieces 20. The energy-concentrating component 10 is mounted on the several foot pieces 20. Each foot piece 20 includes a support portion 201, a recessed mounting portion 203, and a connecting portion 205, which are connected and fixed sequentially from top to bottom, or they can be integrally formed. The support portion 201 at the upper end of the foot piece 20 is used to support the bottom of the pot, and the connecting portion 205 at the lower end of the foot piece 20 is used to mount the base. The two ends of the recessed mounting portion 203 are respectively connected to the support portion 201 and the connecting portion 205. The mounting part 203 is provided with a mounting groove 2031, which is recessed inward from the inner wall of the foot piece 20. The energy-concentrating component 10 includes an outer baffle ring 11 and an inner baffle ring 12. The energy-concentrating component 10 is connected to several foot pieces 20, and the outer baffle ring 11 is connected to the mounting groove 2031 of the foot piece 20. The outer baffle ring 11 is used for wind protection. A windproof groove 111 is formed by recessing the outer side of the outer baffle ring 11 inward along the radial direction of the energy-concentrating component 10, thereby increasing the shape resistance of the windward side of the outer baffle ring to reduce the incoming flow velocity and achieve a significant windproof effect. The inner baffle ring 12 is used for energy concentration. The top of the inner baffle ring 12 is connected to the inner side of the outer baffle ring 11, and the bottom of the inner baffle ring 12 extends downward to form an energy-concentrating space, thereby effectively preventing heat from diffusing downward and strengthening the convective heat exchange with the bottom of the pot, thus increasing the energy concentration effect.

[0053] It should be noted that the outer baffle 11 can be designed with various profiles relative to the incoming flow, and the drag coefficient of a three-dimensional object with different profiles will vary at the Reynolds number. For objects in a fluid, the resistance they experience is mainly of two types: frictional drag and pressure drag. The formula for calculating the drag coefficient in irrotational flow on a smooth, straight wall is: C D = 2*(1 / g*Re)^(1 / 2), where: C D It is the drag coefficient; Re is the Reynolds number, defined as the product of the characteristic length L of the object in the fluid and the velocity V, divided by the kinematic viscosity μ of the fluid, i.e., Re = V * L / μ; g is the acceleration due to gravity (m / s²). 2For objects with other complex shapes or surface roughness, more complex calculation methods or experimental determinations are required. At the same Reynolds number, Re>10 4 Zero-thickness circular plate C D =1.17, while cube C D =1.07; Frontal C of a solid hemisphere D =0.42, while the reverse side C of the solid hemisphere D =1.17; Frontal surface C of the hollow hemispherical shell D =0.38, while the reverse side C of the hollow hemispherical shell D =1.42. Therefore, it can be seen that the drag coefficient of a circular profile is greater than that of a planar profile, and the drag coefficient of the reverse side of a hollow hemispherical shell is greater than that of the reverse side of a solid hemispherical shell. Among these various profiles, the drag coefficient of the reverse side of a hemispherical shell is the largest. It can be concluded that the windbreak groove 111 is recessed radially inward from the outer surface of the outer baffle ring 11 along the energy-concentrating component 10. The windbreak groove 111 increases the drag coefficient of the outer baffle ring 11, thereby effectively reducing the incoming flow velocity and making the windproof effect more significant.

[0054] like Figure 3 As shown, the inner wall surface of the windproof groove 111 is made of arc surface, which can obtain a larger drag coefficient and is conducive to the windproof function of the outer baffle ring 11.

[0055] like Figures 2 to 5 As shown, the outer baffle ring 11 is hemispherical in shape. Since the windproof groove 111 is a reverse hemispherical shell, its resistance coefficient is the largest, which can effectively reduce the incoming flow velocity. This embodiment achieves the best windproof effect.

[0056] like Figure 2 , Figure 5 and Figure 6 As shown, the foot piece 20 has at least one slot, which is recessed inward from the inner wall of the mounting groove 2031, and the outer retaining ring 11 is snapped into the slot.

[0057] In this embodiment, there are two slots, and the upper and lower ends of the outer retaining ring 11 are respectively snapped into the two slots.

[0058] Specifically, in this embodiment, the foot piece 20 has a first slot 202 and a second slot 204. The first slot 202 is located at the upper end of the recessed mounting portion 203, and the second slot 204 is located at the lower end of the recessed mounting portion 203. The first slot 202 and the second slot 204 are recessed inward from the inner wall surface of the mounting groove 2031 from the upper and lower ends, respectively. The first slot 202 and the second slot 204 extend from the inner connection point of the foot piece 20 towards the outer side of the foot piece 20, respectively. The first slot 202 extends upward towards the support portion 201. The first slot 202 extends downwards towards the connecting portion 205 at the lower end of the foot piece 20, while the end of the first slot 202 connected to the mounting groove 2031 on the inner side of the foot piece 20 is lower than the end near the outer side of the foot piece 20. The second slot 204, on the other hand, extends downwards towards the connecting portion 205 at the inner side of the foot piece 20, while the end of the second slot 204 connected to the mounting groove 2031 on the inner side of the foot piece 20 is higher than the end near the outer side of the foot piece 20. Both the first slot 202 and the second slot 204 are arc-shaped, and they respectively engage with the upper and lower ends of the outer retaining ring 11, thus improving the connection stability between the outer retaining ring 11 and the foot piece 20. A gap 40 is left between the outer retaining ring 11 and the mounting groove 2031 of the foot piece 20.

[0059] like Figure 1 , Figure 2 and Figure 4 As shown, the inner wall surface of the inner baffle ring 12 in this embodiment has a flow guiding surface 121, which extends from top to bottom along the direction close to the center of the energy-concentrating component 10.

[0060] Specifically, in this embodiment, the inner baffle ring 12 has a guide surface 121 on its fire-facing surface. The guide surface 121 extends from top to bottom along the direction close to the center of the energy-concentrating component 10, guiding the heat of the gas stove fire along the guide surface 121 towards the center of the energy-concentrating component 10. This guide surface 121 prevents heat from diffusing downwards and blocks heat loss, resulting in better energy concentration.

[0061] like Figure 1 , Figure 2 He Ru Figure 4 As shown, the guide surface 121 in this embodiment is an arc surface.

[0062] Specifically, in this embodiment, the inner wall surface of the inner baffle ring 12 is provided with an arc-shaped flow guide surface 121. When the heat of the furnace fire diffuses outward, it encounters the obstruction of the inner baffle ring 12. When the heat is guided to the center of the energy-concentrating component 10 along the arc-shaped flow guide surface 121, it can be smoothly guided to the center, resulting in a better energy-concentrating effect.

[0063] like Figures 1 to 4 As shown, the inner baffle ring 12 in this embodiment is shaped like a quarter-spherical shell, with the hemispherical shell on the reverse side having the largest drag coefficient. This prevents heat from diffusing outwards and instead directs it towards the center of the energy-concentrating component 10. Furthermore, the structure is simple and easy to manufacture.

[0064] The inner baffle ring 12 is connected at its top to the middle area of ​​the inner side of the outer baffle ring 11, which effectively prevents heat from diffusing downwards and enhances convective heat transfer with the bottom of the pot, thereby increasing the energy concentration effect. At the same time, the structure is simple and easy to assemble.

[0065] like Figure 2 , Figures 4 to 6 As shown, in this embodiment, the inner retaining ring 12 is welded to the outer retaining ring 11. The top of the inner retaining ring 12 is welded to the middle position of the inner side of the outer retaining ring 11. The outer retaining ring 11 and the inner retaining ring 12 are welded together, making the connection more stable and reliable. In daily operation, the positions of the outer retaining ring 11 and the inner retaining ring 12 are not easily moved.

[0066] The outer retaining ring 11 is welded to the foot piece 20. The upper end of the outer retaining ring 11 is welded and snapped into the first slot 202 of the foot piece 20, and the lower end of the outer retaining ring 11 is welded and snapped into the second slot 204 of the foot piece 20. After welding, the connection between the outer retaining ring 11 and the foot piece 20 is more secure.

[0067] The inner retaining ring 12 is welded to the outer retaining ring 11, and the outer retaining ring 11 is also welded to the foot piece 20. The positions of the outer retaining ring 11, the inner retaining ring 12, and the foot piece 20 are all welded and fixed, making them difficult to move and ensuring the stability of the pot support.

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.
