TECHNICAL FIELD
[0001] The utility model relates to the field of kitchen utensils, in particular to a focusing ring, a pot support and a stove. BACKGROUND
[0002] At present, the market mostly realizes the improvement of combustion efficiency through the placement of focusing discs and the like.
[0003] However, the existing focusing discs are mostly large platforms, and soup liquid is prone to residual and causes the focusing discs to rust.
[0004] At the same time, the overflow liquid in the pot above the focusing disc may splash on the focusing disc, which easily extinguishes a small fire and causes safety risks such as gas leakage. SUMMARY
[0005] The utility model solves the technical problem that liquid is easily left in the focusing disc and overflow liquid splashes, and provides a focusing ring, a pot support and a stove.
[0006] The utility model solves the above technical problem through the following technical scheme:
[0007] A focusing ring comprises an outer peripheral wall and an inner peripheral wall.
[0008] The inner peripheral wall is inclined relative to the vertical direction, and the inner side edge of the inner peripheral wall is provided with a downwardly recessed groove and a downwardly extending flange located on the inner peripheral side of the groove.
[0009] The first side wall of the groove close to the flange is provided with a recessed pit towards the inner peripheral side.
[0010] In the present scheme, the double-gradient inner ring flange design of the focusing ring of the pot support is utilized, and when the liquid overflows, due to the height difference between the inner and outer parts of the focusing ring, the soup liquid accumulates a certain amount of kinetic energy due to its own gravity. The double-gradient structure reduces the kinetic energy storage in stages, effectively reduces the splashing and other adverse phenomena caused by the rapid flow of soup liquid. At the same time, the double-gradient changes the flow state of the liquid. That is, when the liquid overflows, the soup liquid flows down from the inclined inner peripheral wall and is first buffered in the groove, reducing the kinetic energy, and when it continues to flow towards the inner peripheral side in the groove, it is secondly buffered by the pit on the first side wall, and the kinetic energy is reduced again, thereby avoiding the splashing of the soup liquid and extinguishing the small fire. At the same time, since the inner peripheral wall of the focusing ring is inclined, the soup liquid will only accumulate at the groove and will not scatter on the entire surface of the focusing ring, thereby avoiding the wide corrosion of the focusing ring by the soup liquid.
[0011] Preferably, the first side wall is inclined towards the inner peripheral side and upwards, and the inclination angle of the first side wall relative to the vertical direction is 30°-60°.
[0012] Preferably, the first side wall comprises a first ring edge and a second ring edge arranged in sequence from the inner circumferential side to the outer circumferential side, the first ring edge and the second ring edge are arranged at an angle in a radial cross-section to form the recess.
[0013] Preferably, the included angle of the first ring edge and the second ring edge is α, wherein 145°>α>170°.
[0014] In this scheme, by controlling the angle α of the slope, 145°>α>170°, the ratio of the inertial force and the viscous force of the soup liquid is optimized by using the Reynolds number effect, thereby reducing the risk of blockage of the soup liquid during flow, avoiding the blockage problem of single direction flow, and reducing the problem of liquid accumulation. Based on the surface tension characteristics possessed by the liquid, the soup liquid presents a significant shrinkage trend during the process of dripping along the flange after passing through the groove and converging to the liquid container, thereby forming a locally spread ideal state, facilitating user scrubbing.
[0015] Preferably, the first ring edge and the second ring edge are both straight plates.
[0016] Preferably, the outer circumferential wall extends in the vertical direction.
[0017] In this scheme, the outer circumferential wall extends in the vertical direction, and the liquid splashed from above is not easy to remain on the outer circumferential wall.
[0018] Preferably, the lower side of the energy gathering ring is open, and the lower edge of the outer circumferential wall has a flow guide surface inclined towards the center and below the energy gathering ring.
[0019] In this scheme, the flow guide surface of the energy gathering ring can guide the liquid flowing down from the outer circumferential wall into the liquid container, facilitating user cleaning.
[0020] Preferably, the outer circumferential wall and the inner circumferential wall are connected by an arc surface.
[0021] In this scheme, the outer circumferential wall and the inner circumferential wall are connected by an arc surface, which can avoid the liquid splashed from above remaining on the upper surface of the energy gathering ring.
[0022] A pot support comprising the energy gathering ring as described above.
[0023] A stove comprising a burner and a pot support as described above, the burner being located at the center of the pot support.
[0024] The positive progress effect of the utility model lies in: the double-gradient inner ring flanging design of the energy collecting ring of the pot support, when liquid overflows, due to the height difference between the inside and outside of the energy collecting ring, the soup liquid will accumulate a certain amount of kinetic energy due to its own gravity. The double-gradient structure reduces the kinetic energy storage in stages, effectively reduces the splashing and other adverse phenomena caused by the rapid flow of soup liquid. At the same time, the double-gradient changes the flow state of the liquid. That is to say, when liquid overflows, the soup liquid flows down from the inclined inner wall and is first buffered in the groove, reducing the kinetic energy, and when it continues to flow to the inner wall side in the groove, it is secondly buffered by the recess on the first side wall, and the kinetic energy is reduced again, thereby avoiding the splashing of the soup liquid and extinguishing the small fire. At the same time, since the inner wall of the energy collecting ring is inclined, the soup liquid will only accumulate at the groove and will not scatter on the entire surface of the energy collecting ring, thereby avoiding the large-scale corrosion of the soup liquid to the energy collecting ring. The pot support and the stove with the above-mentioned energy collecting ring have the same effect as described above. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0034] The present application will be further described below by way of examples with reference to the accompanying drawings, but the present application is not limited to the examples.
[0035] As shown in Figures 1-3 , the present embodiment provides a cooking utensil 100, which comprises a burner 110 and a pot support 130, and the burner 110 is located at the center of the pot support 130.
[0036] As shown in Figure 4 , the pot support 130 comprises a concentrator ring 132 and an angle piece 131, and the angle piece 131 is arranged on the concentrator ring 132 and is uniformly arranged in the circumferential direction of the concentrator ring 132. In the present embodiment, the angle piece 131 is inserted into the concentrator ring 132 and penetrates the concentrator ring 132 in the vertical direction V. However, the present application is not limited thereto, and the angle piece 131 can be connected to the concentrator ring 132 in other existing arrangement manners.
[0037] In the present embodiment, the angle piece 131 and the concentrator ring 132 are combined into one whole to form the pot support 130. However, the present application is not limited thereto, and the pot support 130 can also be arranged separately from the concentrator ring 132, that is, a pot support 130 without the concentrator ring 132 is arranged, and then the concentrator ring 132 is arranged on the pot support 130, and the concentrator ring 132 is formed as a separate component relative to the pot support 130 or a complete component that can be separately detached relative to the pot support 130.
[0038] As shown in Figures 5-8 , the concentrator ring 132 comprises an outer peripheral wall 1321 and an inner peripheral wall 1323; the inner peripheral wall 1323 is inclined relative to the vertical direction V, and the inner side edge of the inner peripheral wall 1323 is provided with a groove 142 recessed downward and a flange 161 extending downward located on the inner peripheral side of the groove 142; the first side wall 1421 of the groove 142 close to the flange 161 is provided with a dimple 151 recessed toward the inner peripheral side.
[0039] With the double-gradient inner circle flanging 161 design of the energy-gathering ring 132 of the pot support 130, when the soup liquid overflows, due to the height difference between the inner and outer parts of the energy-gathering ring 132, the soup liquid will accumulate a certain amount of kinetic energy due to its own gravity. The double-gradient structure reduces the kinetic energy in stages, effectively reducing the splashing and other adverse phenomena caused by the rapid flow of the soup liquid. At the same time, the double-gradient changes the flow state of the liquid. That is, when the soup liquid flows down from the inclined inner wall 1323 due to its own gravity, it is first buffered in the groove 142, reducing the kinetic energy, and when it continues to flow to the inner wall side in the groove 142, it is secondly buffered by the recess 151 on the first side wall 1421, again reducing the kinetic energy, thereby avoiding the splashing of the soup liquid and extinguishing the small fire. At the same time, since the inner wall 1323 of the energy-gathering ring 132 is inclined, the soup liquid will accumulate only at the groove 142 when flowing down, and will not spread over the entire surface of the energy-gathering ring 132, thereby avoiding the corrosion of the soup liquid to the energy-gathering ring 132.
[0040] After the soup liquid passes through the groove 142, it will drip onto the liquid container 120 along the downwardly extending flange 161, which is used to guide the liquid overflowing from the groove 142 or directly flowing out of the groove 142 due to kinetic energy, to drip into the liquid container 120.
[0041] The first side wall 1421 is inclined towards the inner wall side and upwards, and the inclination angle β of the first side wall 1421 relative to the vertical direction V is preferably 30°-60°, more preferably 45°. Since the first side wall 1421 does not form a standard straight plate shape, the inclination angle β of the first side wall 1421 here is the angle between the line connecting the top point and the bottom point of the first side wall 1421 and the vertical direction V.
[0042] The first side wall 1421 includes a first ring edge 1511 and a second ring edge 1512 arranged in sequence from the inner wall side to the outer wall side, and the first ring edge 1511 and the second ring edge 1512 are arranged at an angle in the radial cross-section to form the recess 151.
[0043] The first ring edge 1511 and the second ring edge 1512 are both straight plate shapes, thereby forming a standard angle shape in cross-section.
[0044] As shown in Figure 8 , the angle between the first ring edge 1511 and the second ring edge 1512 is α, where 145°>α>170°.
[0045] By using the Reynolds number effect, by controlling the angle of the slope, 145°>a>170°, the ratio of the inertial force and the viscous force of the soup liquid is optimized, thereby reducing the risk of blockage of the soup liquid in the flow process, avoiding the blockage problem of single direction flow, and reducing the problem of liquid accumulation. Based on the surface tension characteristics possessed by the liquid, the soup liquid presents a clear shrinkage trend after passing through the groove 142 along the flange 161, and then converges to the liquid container 120, thereby forming a locally spread ideal state, facilitating user scrubbing.
[0046] Alternatively, the recess 151 can also be formed in other forms, such as a semicircular recess 151, etc. Forming the recess 151 on the first side wall 1421 can realize secondary buffering.
[0047] The outer peripheral wall 1321 extends along the vertical direction V. The liquid splashed from above is not easy to remain on the outer peripheral wall 1321.
[0048] The lower side of the energy gathering ring 132 is open, and the lower edge of the outer peripheral wall 1321 has a flow guide surface 13211 inclined towards the center and below the energy gathering ring 132.
[0049] The flow guide surface 13211 of the energy gathering ring 132 can guide the liquid flowing down from the outer peripheral wall 1321 into the liquid container 120, facilitating user cleaning.
[0050] At the same time, the flow guide surface 13211 at the lower side of the outer peripheral wall 1321 together with the table top of the stove 100 forms an outwardly expanding and inwardly contracting annular air inlet channel, accelerating the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner 110 and further improving the combustion efficiency of the stove 100.
[0051] The outer peripheral wall 1321 and the inner peripheral wall 1323 are connected by an arc surface 1322. The outer peripheral wall 1321 and the inner peripheral wall 1323 are connected by the arc surface 1322, which can avoid the liquid splashed from above from remaining on the upper surface of the energy gathering ring 132.
[0052] In this embodiment, the energy gathering ring 132 is a hollow structure, which is open below. However, the present application is not limited thereto, and the inner peripheral wall 1323 structure of the present application can also be adapted to a closed energy gathering ring 132, or a plurality of sandwiched layers or an energy gathering ring 132 with internal fillers.
[0053] As Figure 6As shown, the inner peripheral wall 1323 of the energy gathering ring 132 is further provided with an edge 141 extending inward along the radial direction from the corner of the energy gathering ring 132 to the upper edge of the second side wall 1422 of the groove 142, which is opposite to the first side wall 1421. The second side wall 1422 has no obvious boundary with the part of the outer peripheral side of the groove 142 on the inner peripheral wall 1323 of the energy gathering ring 132, and the part of the first side wall 1421 at the same height is taken as the second side wall 1422. The first side wall 1421 and the second side wall 1422 are connected by an arc-shaped surface, so as to avoid the occurrence of a cleaning dead angle.
[0054] Compared with the conventional pot support 130, the edge 141 has a unique profile design, which has a guiding effect on the overflow liquid, and the soup liquid will quickly flow downward along the profile groove 142 and the edge, which effectively reduces the accumulation of the soup liquid, reduces the corrosion risk of the pot support 130 itself, and prolongs the service life.
[0055] The profile structure of the edge 141 can disperse external force along the rhombus and the profile direction, so as to have better stability, and meanwhile, the moment of inertia and the cross-sectional modulus of the pot support 130 itself are increased, so that the strength of the pot support 130 itself is greatly improved.
