Abstract
Description
Technical Field
[0001] The present application relates to the technical field of gas stoves, and in particular to an energy collecting hood for a gas stove and a gas stove. Background Art
[0002] The high-temperature flame and high-temperature smoke generated by the combustion of the gas stove transfer heat to the cookware. The high-temperature flame and smoke will transfer heat to surrounding objects such as the stove panel, the legs of the energy-gathering hood, etc., resulting in heat loss. When the cookware is used for cooking, the ratio of the actual heat absorbed to the heat generated by the combustion of the gas stove is usually around 63% to 65%. The heat obtained by the cookware when the user is cooking is too low to meet the firepower requirements for Chinese stir-frying, etc.
[0003] The related art provides a gas stove, wherein the energy-gathering cover comprises an upper cover and a lower cover, the claw is connected to the upper cover, the lower cover is arranged below the upper cover, and defines a cavity with the upper cover, and the air in the cavity isolates the heat transferred downward by the upper cover and the claw. The lower cover is provided with a through hole, and the energy-gathering cover also comprises a connecting sleeve, one end of which is connected to the claw, and the other end of which is inserted into the through hole of the lower cover, and the upper cover is connected to the lower cover through the connecting sleeve.
[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] One end of the sleeve is connected to the support claw on the upper cover, and the other end extends into the through hole of the lower cover. Even if the air in the cavity will isolate part of the heat from transferring downward, some heat will still be transferred along the sleeve to the lower cover, and indirectly transferred to the support foot and the stove panel, reducing the heat transfer efficiency of the energy-concentrating cover.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0045] Combination Figure 1-8 As shown, according to the first aspect of the present embodiment, there is provided an energy-gathering hood for a gas stove, comprising an upper hood 10, a lower hood 20 and a connecting piece 40, wherein the upper hood 10 comprises a first hood 11 and a second hood 12 connected to each other, and the first hood 11 and the second hood 12 define a first cavity 13, and the first hood 11 is arranged above the second hood 12; the lower hood 20 is arranged below the upper hood 10, and defines a second cavity 21 with the upper hood 10; the connecting piece 40 is arranged between the first cavity 13 and the second cavity 21, and there is a gap with the first hood 11; wherein the connecting piece 40 is used to connect the upper hood 10 and the lower hood 20, and to make the upper hood 10 suspended relative to the lower hood 20.
[0046] The gas stove provided in the embodiment of the present disclosure includes a burner 50, and the burner 50 is provided with a fire outlet 51. The energy collecting cover is arranged on the outside of the burner 50. The upper cover body 10 includes a first cover body 11 and a second cover body 12. From top to bottom, the first cover body 11, the second cover body 12 and the lower cover body 20 are arranged in sequence. The fire outlet 51 faces the first cover body 11, and the air-fuel mixed gas flowing out of the fire outlet 51 is in direct contact with the first cover body 11. The lower cover body 20 is connected to the stove panel through the support legs.
[0047] One way to improve the heat transfer efficiency of the energy-gathering hood is to reduce the heat transfer to the stove panel and the legs, thereby reducing heat loss. The first cover body 11, the second cover body 12 and the lower cover body 20 are arranged in sequence from top to bottom to define the first cavity 13 and the second cavity 21. Air exists in the cavity, and the heat resistance of the air is used to limit the heat transfer from the first cover body 11 to the lower cover body 20, thereby reducing heat loss.
[0048] The connecting member 40 is disposed in the first cavity 13 and the second cavity 21 and is not in contact with the first cover body 11 , so that the heat of the first cover body 11 can be reduced from being transferred to the lower cover body 20 along the connecting member.
[0049] Optionally, the connecting member 40 is disposed on the non-edge side of the upper cover body 10 and the lower cover body 20 .
[0050] The upper cover 10 and the lower cover 20 are connected only by the connecting member 40. Since the connecting member 40 is arranged on the non-edge side, the upper cover 10 can be suspended relative to the lower cover 20 by adjusting the position of the connecting member 40. That is, there is a gap between the outer edge of the upper cover 10 and the outer edge of the lower cover 20, and there is a gap between the inner edge of the upper cover 10 and the inner edge of the lower cover 20, which reduces the heat transfer between the upper cover 10 and the lower cover 20.
[0051] The disclosed embodiment can effectively reduce the heat transfer from the upper cover 10 to the lower cover 20, reduce the heat transfer to the legs, the cooker panel and other positions, and reduce the heat dissipation. Sufficient heat is retained in the first cover 11 and transferred to the cooker, thereby improving the heat transfer efficiency of the energy-gathering cover.
[0052] Optionally, combined Figure 2 As shown, the connecting member 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is connected to the second cover body 12, and the second connecting member 42 is connected to the lower cover body 20 and cooperates with the first connecting member 41 to connect the lower cover body 20 to the second cover body 12.
[0053] Optionally, the first connecting member 41 includes a rivet 411 with an internal thread at the center.
[0054] Optionally, the second connecting member 42 includes a screw 421 .
[0055] The lower cover body 20 is provided with a countersunk hole 22 along the direction of the upper cover body 10, and the second cover body 12 is provided with a through hole corresponding to the countersunk hole 22; wherein, the rivet 411 is inserted into the through hole and fixedly connected to the second cover body 12, and the screw 421 passes through the countersunk hole 22 from bottom to top and is connected with the internal thread of the rivet 411 to connect the lower cover body 20 with the second cover body 12, thereby connecting the lower cover body 20 with the upper cover body 10.
[0056] Optionally, the energy gathering hood for the gas stove further includes a first heat insulating member 60 , and the first heat insulating member 60 is disposed between the first connecting member 41 and the second connecting member 42 .
[0057] The first heat insulating member 60 is disposed between the first connecting member 41 and the second connecting member 42 , that is, the first heat insulating member 60 is disposed between the lower end surface of the countersunk hole 22 and the upper end surface of the rivet 411 , so as to reduce heat transfer between the first connecting member 41 and the second connecting member 42 .
[0058] Optionally, the first thermal insulation member 60 includes metal sheet, high temperature resistant rubber, aerogel, felt, etc.
[0059] Optionally, combined Figure 2 and Figure 3 As shown, from the inside to the outside, the upper cover body 10 includes a first inner edge 14 and a first outer edge 15, and the lower cover body 20 includes a second inner edge 23 and a second outer edge 24. When the upper cover body 10 is suspended relative to the lower cover body 20, the first inner edge 14 and the second inner edge 23 are arranged opposite to each other and there is an inner edge gap 25; the first outer edge 15 and the second outer edge 24 are arranged opposite to each other and there is an outer edge gap 26; the energy-gathering cover also includes a second heat insulating member 70, and the second heat insulating member 70 is arranged in the inner edge gap 25 and / or the outer edge gap 26. Among them, Figure 2 Arrows indicate inward and outward directions.
[0060] The upper cover 10 and the lower cover 20 are connected by a connecting member 40, and the upper cover 10 is suspended relative to the lower cover 20, so there will be an outer edge gap 26 and an inner edge gap 25. When the cookware is placed on the energy-gathering cover, the gap distance of the outer edge gap 26 or the inner edge gap 25 may be reduced to zero due to the gravity of the cookware, which will cause the edge positions of the upper cover 10 and the lower cover 20 to contact, resulting in heat transfer. The second heat insulating member 70 is arranged in the inner edge gap 25 and / or the outer edge gap 26 to prevent heat transfer between the upper cover 10 and the lower cover 20.
[0061] Optionally, a second thermal insulation member 70 is disposed in the outer edge gap 26 .
[0062] The upper cover 10 is provided with a claw 30, which is used to support the cookware. The claw 30 is usually provided on the side close to the first outer edge 15, so that the weight of the energy collecting cover is concentrated on the first outer edge 15, and the outer edge gap 26 is easily squeezed. Therefore, only by providing the second heat insulating member 70 in the outer edge gap 26, the effect of reducing the heat transfer between the upper cover 10 and the lower cover 20 can be achieved.
[0063] Optionally, the second thermal insulation member 70 includes metal sheet, high temperature resistant rubber, aerogel, felt, etc.
[0064] Optionally, combined Figure 4 As shown, at least a portion of the second cover body 12 is recessed toward the lower cover body 20 to form a slot 121; the lower cover body 20 includes a second outer edge 24, at least a portion of the second outer edge 24 protrudes toward the upper cover body 10 to form a protrusion 27, the protrusion 27 is arranged corresponding to the slot 121, and the second thermal insulation member 70 is arranged between the protrusion 27 and the slot 121.
[0065] By providing the protrusion 27, the upper cover body 10 is prevented from directly contacting the lower cover body 20, and even if the second heat insulating member 70 is compressed, the gap distance between the upper cover body 10 and the lower cover body 20 is ensured.
[0066] Optionally, the first thermal insulation member 60 and the second thermal insulation member 70 are both elastic, and when the first connecting member 41 is connected to the second connecting member 42 , the first thermal insulation member 60 and the second thermal insulation member 70 are squeezed to adjust the size of the inner edge gap 25 and the outer edge gap 26 .
[0067] By selecting the first thermal insulation member 60 and the second thermal insulation member 70 with elasticity and adjusting the connection strength of the first connecting member 41 and the second connecting member 42, the distance between the outer edge gap 26 and the inner edge gap 25 can be adjusted.
[0068] It can be understood that by adjusting the tightening degree of the rivet 411 and the screw 421, the distance between the outer edge gap 26 and the inner edge gap 25 can be adjusted, that is, the degree of compression of the first thermal insulation member 60 and the second thermal insulation member 70 can be adjusted. The first thermal insulation member 60 and the second thermal insulation member 70 can be compressed to achieve the function of blocking heat transfer, and the first thermal insulation member 60 and the second thermal insulation member 70 can be prevented from being over-compressed, resulting in the gap distance of the outer edge gap 26 and / or the inner edge gap 25 approaching zero.
[0069] Optionally, combined Figure 5-7 As shown, the first cover body 11 includes a first protrusion 111, a second protrusion 112 and a third protrusion 113 which are arranged in sequence from the inside to the outside; the first protrusion 111 is connected to the second protrusion 112 to define a first trapped vortex cavity 114, and the second protrusion 112 is connected to the third protrusion 113 to define a second trapped vortex cavity 115, wherein the relative height range of the second protrusion 112 and the first protrusion 111 is -5mm to 15mm; and / or the relative height range of the third protrusion 113 and the first protrusion 111 is 10mm to 25mm.
[0070] From the inside to the outside, the first trapped vortex cavity 114 and the second trapped vortex cavity 115 are arranged in sequence, and the burner 50 is provided with a fire outlet 51. After the high-temperature flame and smoke discharged from the fire outlet 51 flow to the first trapped vortex cavity 114, a trapped vortex flow is formed, and the smoke flow velocity is reduced, and heat is exchanged with the bottom of the pot. After passing through the second trapped vortex cavity 115 again, a trapped vortex flow is formed, and the smoke flow velocity is further reduced, and heat is continued to be exchanged with the bottom of the pot. The two trapped vortex cavities increase the vortex time of the high-temperature flame and smoke, that is, increase the contact time between the high-temperature flame and smoke and the pot, so that the pot can be fully heat-transferred. Improve the thermal efficiency of the gas stove.
[0071] The relative height range between the second protrusion 112 and the first protrusion 111 is -5mm to 15mm. When the relative height range between the second protrusion 112 and the first protrusion 111 exceeds 15mm, that is, the second protrusion 112 is higher than the first protrusion by more than 15mm, it is not conducive to the flow of smoke from the first trapped vortex cavity 114 to the second trapped vortex cavity 115; when the relative height between the second protrusion 112 and the second protrusion 112 is too small, that is, the second protrusion 112 is significantly lower than the first protrusion 111, the vortex time of smoke in the first trapped vortex cavity 114 will be shortened, which is not conducive to the transfer of heat to the cookware. Figure 7 Here, e represents the height of the second protrusion 112 relative to the first protrusion 111 .
[0072] The relative height range of the third protrusion 113 and the first protrusion 111 is 10 mm to 25 mm. When the height of the third protrusion 113 relative to the first protrusion 111 exceeds 25 mm, that is, the third protrusion 113 is significantly higher than the first protrusion 111, it is not conducive to the exhaust of smoke from the energy-gathering hood, which may easily lead to excessive smoke; when the height of the third protrusion 113 relative to the first protrusion 111 is less than 10 mm, it is not conducive to the smoke staying in the first vortex zone and the second vortex cavity 115, and it is not conducive to transferring heat to the cookware. Figure 6 Here, h represents the height of the third protrusion 113 relative to the first protrusion 111 .
[0073] Exemplarily, the height of the second protrusion 112 relative to the first protrusion 111 may be -3 mm, 0 mm, 5 mm, or 10 mm.
[0074] Exemplarily, the height of the third protrusion 113 relative to the first protrusion 111 may be 13 mm, 16 mm, 20 mm, or 23 mm.
[0075] Optionally, the energy focusing hood for the gas stove also includes a burner 50, which is provided with a fire hole 51, and the fire hole 51 faces the first trapped vortex cavity 114, so that the high-temperature flue gas flowing out of the fire hole 51 passes through the first trapped vortex cavity 114 and the second trapped vortex cavity 115 in sequence; wherein the relative height range of the first protrusion 111 to the bottom wall 511 of the fire hole 51 is -5mm to 5mm.
[0076] When the relative height between the first protrusion 111 and the bottom wall 511 of the fire hole 51 exceeds 5 mm, it is not conducive for the high-temperature flue gas discharged from the fire hole 51 to flow into the first trapped vortex cavity 114. When the relative height between the first protrusion 111 and the bottom wall 511 of the fire hole 51 is lower than -5 mm, the high-temperature flue gas will float upward due to its low density, so it is not conducive for the high-temperature flue gas to flow into the first trapped vortex cavity 114. Figure 6 In the figure, c represents the height of the first protrusion 111 relative to the bottom wall 511 of the fire outlet hole 51 .
[0077] Exemplarily, the relative heights between the first protrusion 111 and the bottom wall 511 of the fire outlet hole 51 are -3 mm, 0 mm, 3 mm, and 5 mm.
[0078] Optionally, the energy collecting cover for the gas stove further includes: a first inner wall section 1111, a second inner wall section 1121, and a third inner wall section 1131, which are all inclined upward and arranged in sequence from the inside to the outside; a first outer wall section 1112 and a second outer wall section 1122, which are all inclined downward and arranged in sequence from the inside to the outside; and a third outer wall section 1132; wherein the first inner wall section 1111 is connected to the first outer wall section 1112 to form a first protrusion 111, and the second inner wall section 1121 is connected to the first outer wall section 1122 to form a first protrusion 111, and the second inner wall section 1121 is connected to the first outer wall section 1122 to form a first protrusion 111, and the second inner wall section 1121 is connected to the first outer wall section 1122 to form a first protrusion 111, and the second inner wall section 1121 is connected to the first outer wall section 1121 ... The wall segment 1121 is connected to the second outer wall segment 1122 to form a second protrusion 112, and the third inner wall segment 1131 is connected to the third outer wall segment 1132 to form a third protrusion 113; the angle between the first inner wall segment 1111 and the vertical direction is in the range of 0° to 80°; and / or, the angle between the second inner wall segment 1121 and the vertical direction is in the range of 0° to 80°; and / or, the angle between the third inner wall segment 1131 and the vertical direction is in the range of 0° to 80°.
[0079] In this embodiment, the angle range between the first inner wall segment 1111 and / or the second inner wall segment 1121 and / or the third inner wall segment 1131 and the vertical direction is 0° to 80°. If the angle between the first inner wall segment 1111 and / or the second inner wall segment 1121 and / or the third inner wall segment 1131 and the vertical direction is less than 0°, the first inner wall segment 1111 and / or the second inner wall segment 1121 and / or the third inner wall segment 1131 will be tilted toward the fire outlet 51, hindering the discharge of smoke and increasing the flow resistance of the smoke, which is not conducive to the smoke flowing through the first trapped vortex cavity 114 and the second trapped vortex cavity 115 in sequence. The included angle between the first inner wall section 1111 and / or the second inner wall section 1121 and / or the third inner wall section 1131 and the vertical direction exceeds 80°, which reduces the height of the first protrusion 111 and / or the second protrusion 112, affects the depth of the first trapped vortex cavity 114 and / or the second trapped vortex cavity 115, and is not conducive to the retention of the flue gas vortex. Figure 8 In FIG. 1 , ∠A represents the angle between the first inner wall segment 1111 and the vertical direction.
[0080] Exemplarily, the angle between the first inner wall segment 1111 and the vertical direction is 20°, 40°, or 50°.
[0081] The included angles between the second inner wall section 1121 and the vertical direction are 25°, 30°, and 50°.
[0082] The angles between the third inner wall section 1131 and the vertical direction are 20°, 45°, and 60°.
[0083] From inside to outside, the first outer wall section 1112 and the second outer wall section 1122 are both inclined downward, which is conducive to the first outer wall section 1112 and the first inner wall section 1111 being arranged relative to each other to form the first protrusion 111, and the second outer wall section 1122 and the second inner wall section 1121 being arranged relative to each other to form the second protrusion 112.
[0084] Optionally, the angle between the first outer wall section 1112 and the vertical direction is in the range of 90° to 180°; and / or the angle between the second outer wall section 1122 and the vertical direction is in the range of 90° to 180°. Figure 8 In FIG. 1 , ∠B represents the angle between the second outer wall segment 1122 and the vertical direction.
[0085] When the angle between the first outer wall section 1112 and / or the second outer wall section 1122 and the vertical direction exceeds 180°, it is not conducive to forming the first protrusion 111 and / or the second protrusion 112 with the first inner wall section 1111 and / or the second inner wall section 1121. When the angle between the first outer wall section 1112 and / or the second outer wall section 1122 and the vertical direction is less than 90°, the depth of the first trapped vortex cavity 114 and / or the second trapped vortex cavity 115 is affected.
[0086] Exemplarily, the angle between the first outer wall segment 1112 and the vertical direction is 120°, 140°, or 150°.
[0087] The included angles between the second outer wall section 1122 and the vertical direction are 130°, 145°, and 160°.
[0088] Optionally, combined Figure 3 As shown, the energy focusing hood for the gas stove also includes a claw 30, which is arranged on the upper cover body 10, and the end of the claw 30 away from the upper cover body 10 and the third protrusion 113 define a smoke exhaust gap; wherein the range of the smoke exhaust gap is 3mm to 15mm.
[0089] In this embodiment, if the smoke exhaust gap is too large, exceeding 15mm, the height angle of the claw 30 increases the gap distance between the cookware and the energy collecting cover, which is not conducive to heat transfer from the energy collecting cover to the cookware. If the smoke exhaust gap is too small, less than 3mm, it is not conducive to smoke exhaust. Figure 3 The a in the middle represents the smoke exhaust gap.
[0090] Exemplarily, the smoke exhaust gap ranges from 5 mm, 8 mm, and 12 mm.
