Description

Technical Field

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

[0002] During operation, the stove requires additional air, and the resulting air temperature rise leads to energy loss. Existing pot support designs use an air layer inside the energy-concentrating ring for insulation, but insufficient air supply during gas combustion results in incomplete combustion. Furthermore, high levels of smoke often occur, indicating incomplete combustion, and heat loss is more likely. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problem that existing stoves often produce high levels of smoke during combustion, i.e., incomplete combustion and easy heat loss, and to provide a pot support device and a stove containing the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A pot support device includes an energy-concentrating ring and a plurality of 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, which are 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 ring is embedded in the plurality of mounting grooves so that the energy-concentrating ring is mounted and connected to the plurality of foot pieces. A supplementary air gap is formed between the bottom of the energy-concentrating ring and the base plate. The bottom end of the outer side of the energy-concentrating ring has a first guide surface. The first guide surface extends from top to bottom along a direction close to the center of the energy-concentrating ring, and the bottom of the first guide surface extends into the supplementary air gap. The energy-concentrating ring has a vortex cavity. The vortex cavity is recessed inward from the inner wall surface of the energy-concentrating ring along the radial direction of the energy-concentrating ring so that the flue gas forms a vortex in the vortex cavity.

[0006] In this design, the pot support device includes an energy-concentrating ring and several foot pieces. Each foot piece includes a support portion, a recessed mounting portion, and a connecting portion connected sequentially from top to bottom. The support portion supports the bottom of the pot, and the connecting portion is used to mount the base plate. The recessed mounting portion connecting the support portion and the connecting portion has mounting grooves recessed inward from the inner wall of the foot piece. The energy-concentrating ring is embedded in several mounting grooves so that it is mounted and connected to several foot pieces. The mounting grooves stably connect and fix the energy-concentrating ring to the foot pieces and also create a supplementary air gap between the bottom of the energy-concentrating ring and the base plate. The bottom end of the outer side of the energy-concentrating ring has a first guide surface. The first guide surface extends from top to bottom along the direction close to the center of the energy-concentrating ring, and the bottom of the first guide surface extends into the supplementary air gap. External air can be introduced into the supplementary air gap along the first guide surface to perform secondary air supplementation, so that the gas combustion obtains sufficient air, effectively avoiding incomplete combustion due to insufficient supplementary air during gas combustion and thus preventing the generation of flue gas, promoting the complete combustion of flue gas, and improving efficiency. The energy-concentrating ring has a vortex cavity. The vortex cavity is concave outward from the inner wall of the energy-concentrating ring along the radial direction of the energy-concentrating ring, so that the flue gas forms a vortex in the vortex cavity. The generation of high-temperature vortex can lift the high-temperature flue gas, so that the high-temperature flue gas can contact the bottom of the pot as soon as possible, extend the heat exchange distance, improve the convective heat transfer efficiency, and improve the thermal efficiency.

[0007] Preferably, the inner wall of the vortex cavity is arc-shaped, and the angle of the arc is not less than 180 degrees.

[0008] In this design, the inner wall of the vortex cavity is arc-shaped, and the angle of the arc is not less than 180 degrees. The arc-shaped inner wall of the vortex cavity is more conducive to the formation of vortices in the cavity, which retains the flue gas in the cavity to achieve the effect of temperature increase, promotes the complete combustion of flue gas, and improves efficiency.

[0009] Preferably, the first guide surface is an arc surface.

[0010] In this design, the first guide surface is an arc surface, and the secondary replenishment air is introduced into the center of the energy-concentrating circle more easily by passing through the arc surface of the first guide surface.

[0011] Preferably, a gap is formed between the top of the energy-concentrating ring and the bottom of the pot, and the top of the outer side of the energy-concentrating ring has a second guide surface, which is located above the first guide surface. The second guide surface extends from bottom to top along a direction close to the center of the energy-concentrating ring, and the top of the second guide surface extends into the gap.

[0012] In this design, a gap is formed between the top of the energy-concentrating ring and the bottom of the pot. The top of the outer side of the energy-concentrating ring has a second guide surface, located above the first guide surface. The second guide surface extends from bottom to top along a direction close to the center of the energy-concentrating ring, with its top extending into the gap. External air can be introduced from bottom to top along the second guide surface, allowing more air to enter the gap. This ensures sufficient air for gas combustion, effectively preventing incomplete combustion due to insufficient air supply and thus avoiding the generation of flue gas. It promotes complete combustion of flue gas and improves efficiency. Simultaneously, the second guide surface allows external air to enter the energy-concentrating ring through the gap for combustion, preventing some flue gas from escaping. This further allows the high-temperature flue gas to contact the bottom of the pot more quickly, extending the heat exchange distance, improving convective heat transfer efficiency, and increasing thermal efficiency.

[0013] Preferably, the second guide surface is an arc surface.

[0014] In this design, the second guide surface is an arc surface, which allows some of the secondary supplementary air to be introduced into the center of the energy-concentrating ring more easily and without obstruction through the upper second guide surface.

[0015] Preferably, the bottom of the second guide surface and the top of the first guide surface have a smooth transition.

[0016] In this design, the bottom of the second guide surface smoothly transitions to the top of the first guide surface. During secondary air introduction, the air is divided into upper and lower parts at the connection between the first and second guide surfaces, allowing for smooth and unobstructed introduction of the two parts of air into the center of the energy-concentrating ring from the upper and lower parts respectively. Furthermore, the design is easy to manufacture.

[0017] Preferably, the top of the energy-concentrating ring has an overflow-proof surface that extends downwards at an angle from the outside in.

[0018] In this design, the top of the energy-concentrating ring has an anti-overflow surface that slopes downwards from the outside in. If liquid overflows during cooking, it can drip down to the bottom of the pan through the anti-overflow surface.

[0019] Preferably, the anti-overflow surface extends inward and downward from the top of the second guide surface, and there is a smooth transition between the anti-overflow surface and the second guide surface.

[0020] In this design, the anti-overflow surface extends inward and downward from the top of the second guide surface, with a smooth transition between the anti-overflow surface and the second guide surface. If liquid drips onto the second guide surface first during cooking, it can smoothly slide onto the anti-overflow surface and then drip down to the bottom of the pan. Furthermore, it is easy to manufacture and process.

[0021] Preferably, the energy-concentrating ring and the foot piece are welded together.

[0022] In this solution, the energy-concentrating coil and the foot piece are welded together, and the energy-concentrating coil is embedded in the foot piece for connection. Welding and fixing can achieve a more stable effect.

[0023] A cooker unit includes a pot support device as described above.

[0024] 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.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] The pot support device and stove including it of this utility model extend into the supplementary air gap through the bottom of the first guide surface. External air can be introduced into the supplementary air gap along the first guide surface, thereby providing secondary air supply. This ensures sufficient air for gas combustion, effectively preventing incomplete combustion due to insufficient supplementary air and thus avoiding the generation of flue gas. It promotes complete combustion of flue gas and improves efficiency. The energy-concentrating ring has a vortex cavity, which is concave outward from the inner wall of the energy-concentrating ring along the radial direction of the ring. This causes the flue gas to form a vortex within the vortex cavity. The generation of the high-temperature vortex can raise the high-temperature flue gas, allowing it to contact the bottom of the pot more quickly, extending the heat exchange distance, improving convective heat transfer efficiency, and increasing thermal efficiency.

[0045] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described below.

[0046] This utility model provides a stove that includes a pot support device, which is installed on a base and used to support the bottom of the pot.

[0047] like Figures 1 to 6 As shown, the pot support device includes an energy-concentrating ring 20 and several foot pieces 10. Each foot piece 10 includes a support portion 101 for supporting the bottom of the pot, a recessed mounting portion 102, and a connecting portion 103 for mounting the base plate, connected sequentially from top to bottom. The recessed mounting portion 102 has a mounting groove 1021 recessed inward from the inner wall of the foot piece 10. The energy-concentrating ring 20 is embedded in the mounting grooves 1021 so that the energy-concentrating ring 20 is mounted and connected to the foot pieces 10. A supplementary air gap 30 is formed between the bottom of the 0 and the chassis. The bottom end of the outer side of the energy-concentrating ring 20 has a first guide surface 202. The first guide surface 202 extends from top to bottom along the direction close to the center of the energy-concentrating ring 20, and the bottom of the first guide surface 202 extends into the supplementary air gap 30. The energy-concentrating ring 20 has a vortex cavity 201. The vortex cavity 201 is recessed from the inner wall surface of the energy-concentrating ring 20 along the radial direction of the energy-concentrating ring 20, so that the flue gas forms a vortex in the vortex cavity 201.

[0048] Specifically, in this embodiment, the energy-concentrating ring 20 is connected to several foot pieces 10. Each foot piece 10 includes a support portion 101, a recessed mounting portion 102, and a connecting portion 103, which are connected sequentially from top to bottom. The support portion 101 is used to support the bottom of the pot. The support portion 101 includes a slope that transitions from a flat surface to a downward slope extending towards the center of the energy-concentrating ring 20, so that in actual use, both flat-bottomed pots and woks with pointed bottoms can be placed on it, and the bottom of the pot can be stably supported by the foot pieces 10. The recessed mounting portion 102 is provided with a mounting groove 1021, which is recessed outward from the inner wall of the foot piece 10. Its cross-section is semi-circular, and it smoothly transitions with the upper support portion 101 and the lower connecting portion 103. The energy-concentrating ring 20 is embedded in several mounting grooves 1021. The convex part of the energy-concentrating ring 20 and the concave part of the mounting groove 1021 fit together, so that the energy-concentrating ring 20 and the foot pieces 10 are stably installed and connected. The connecting part 103 of the foot piece 10 is used to be installed on the chassis. The bottom outer side of the connecting part 103 is provided with a buckle structure, and a corresponding slot is opened on the chassis so that the connecting part 103 is buckled to the chassis and thus fixedly connected to the chassis.

[0049] After the energy-concentrating ring 20 is installed and connected to the foot plate 10, a supplementary air gap 30 is formed between the bottom of the energy-concentrating ring 20 and the chassis. The bottom end of the outer side of the energy-concentrating ring 20 has a first guide surface 202. The first guide surface 202 extends from top to bottom along the direction close to the center of the energy-concentrating ring 20, which can guide external air to be introduced into the center of the energy-concentrating ring 20 from top to bottom along the first guide surface 202. The bottom of the first guide surface 202 extends into the supplementary air gap 30, and external air can be introduced into the supplementary air gap 30 along the first guide surface 202, so that more air can be obtained in the supplementary air gap 30, so that the high-temperature flue gas can be mixed with sufficient supplementary air for secondary mixing, so that the gas combustion can obtain sufficient air, effectively avoiding the situation of incomplete combustion due to insufficient supplementary air during gas combustion, thus preventing the generation of flue gas, promoting the complete combustion of flue gas, and improving efficiency.

[0050] The energy-concentrating ring 20 has a vortex cavity 201. The vortex cavity 201 is recessed radially outward from the inner wall of the energy-concentrating ring 20, so that the flue gas forms a vortex within the vortex cavity 201. The flue gas after combustion flows into the vortex cavity 201. The generation of the high-temperature vortex can lift the high-temperature flue gas, allowing it to contact the bottom of the pot more quickly, extending the heat exchange distance, improving the convective heat transfer efficiency, and thus improving the thermal efficiency.

[0051] like Figure 2 As shown, the inner wall of the vortex cavity 201 in this embodiment is an arc, and the angle of the arc is not less than 180 degrees.

[0052] Specifically, in this embodiment, the inner wall of the vortex cavity 201 is arc-shaped, making it easier for the flue gas inside the vortex cavity 201 to form a swirling flow and obtain a stable vortex. The flue gas retained in the cavity achieves the effect of temperature increase. Moreover, the angle of the arc is not less than 180 degrees, and the resulting vortex is more likely to entrain incompletely burned gas, promote the complete combustion of flue gas, and improve efficiency.

[0053] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first guide surface 202 in this embodiment is an arc surface.

[0054] Specifically, in this embodiment, the first guide surface 202 is an arc surface. When external air is introduced downward along the first guide surface 202 at the center line position of the energy-concentrating ring 20, the arc surface introduces the external air without obstruction, and the air can be smoothly introduced from the lower part of the energy-concentrating ring 20 to the center of the energy-concentrating ring 20.

[0055] like Figure 1 and Figure 5 As shown, in this embodiment, a gap is formed between the top of the energy-concentrating ring 20 and the bottom of the pot. The top of the outer side of the energy-concentrating ring 20 has a second guide surface 203. The second guide surface 203 is located above the first guide surface 202. The second guide surface 203 extends from bottom to top along the direction close to the center of the energy-concentrating ring 20, and the top of the second guide surface 203 extends into the gap.

[0056] Specifically, in this embodiment, a gap is formed between the top of the energy-concentrating ring 20 and the bottom of the pot. The top of the outer side of the energy-concentrating ring 20 has a second guide surface 203. The second guide surface 203, located above the first guide surface 202, is connected to the first guide surface 202. The second guide surface 203 extends from bottom to top along a direction close to the center of the energy-concentrating ring 20, and the top of the second guide surface 203 extends into the gap formed between the top of the energy-concentrating ring 20 and the bottom of the pot. External air flows along the second guide surface 203 towards the gap and is introduced into the center of the energy-concentrating ring 20, allowing more air to be obtained into the gap. This ensures sufficient air for gas combustion, effectively preventing incomplete combustion due to insufficient air supply and thus avoiding the generation of flue gas. This promotes complete combustion of flue gas and improves efficiency. At the same time, the second guide surface 203 allows external air to enter the energy-concentrating ring 20 through the gap for combustion, preventing some flue gas from escaping. This further allows the high-temperature flue gas to contact the bottom of the pot as quickly as possible, extending the heat exchange distance, improving convective heat exchange efficiency, and increasing thermal efficiency.

[0057] like Figure 5 As shown, the second guide surface 203 in this embodiment is an arc surface.

[0058] Specifically, in this embodiment, the second guide surface 203 is an arc surface. When external air is introduced upward along the second guide surface 203 at the center line position of the energy-concentrating ring 20, the arc surface introduces the external air without obstruction, and the air can be smoothly introduced from the upper part of the energy-concentrating ring 20 to the center of the energy-concentrating ring 20.

[0059] like Figure 1 , Figure 5 and Figure 6 As shown, the bottom of the second guide surface 203 and the top of the first guide surface 202 in this embodiment have a smooth transition.

[0060] Specifically, in this embodiment, the connection between the second guide surface 203 at the upper part of the center line of the energy-concentrating ring 20 and the first guide surface 202 at the lower part is smooth, and the bottom of the second guide surface 203 and the top of the first guide surface 202 smoothly transition into one piece, which can be directly integrally formed during manufacturing, making processing and manufacturing convenient.

[0061] like Figure 3 and Figure 5 As shown, the top of the energy-concentrating ring 20 in this embodiment has an anti-overflow surface 204, which extends downward at an angle from the outside to the inside.

[0062] Specifically, in this embodiment, the top of the energy-concentrating ring 20 has an overflow-proof surface 204. The second guide surface 203 of the energy-concentrating ring 20 extends from the top and connects to the overflow-proof surface 204. The overflow-proof surface 204 extends radially from the outside to the inside towards the center of the energy-concentrating ring 20 and is curved downwards. In actual use, if there is overflow, it will drip down along the overflow-proof surface 204, thus preventing dirt accumulation in other parts of the pot support and making it easier to clean.

[0063] like Figure 5 As shown, in this embodiment, the anti-overflow surface 204 extends inward and downward from the top of the second guide surface 203, and there is a smooth transition between the anti-overflow surface 204 and the second guide surface 203.

[0064] Specifically, in this embodiment, the anti-overflow surface 204 and the second guide surface 203 on the upper part of the energy-concentrating ring 20 are smoothly connected. The second guide surface 203 extends inward and downward from the top and smoothly transitions to the anti-overflow surface 204. During manufacturing, the second guide surface and the anti-overflow surface can also be directly integrally formed, which is convenient for processing and manufacturing.

[0065] like Figures 1 to 3 As shown, in this embodiment, the energy-concentrating ring 20 and the foot piece 10 are welded together.

[0066] Specifically, after the energy-concentrating ring 20 is embedded in the mounting groove 1021 of the recessed mounting portion 102 of several foot pieces 10, the energy-concentrating ring 20 and the corresponding foot piece 10 are welded together, so that the connection position between the energy-concentrating ring 20 and the foot piece 10 is fixed and will not be displaced, thus achieving a more stable and reliable connection.

[0067] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. 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.
