Description

Technical Field

[0001] The present application relates to the technical field of stoves, and in particular to a pot rack and a stove. Background Art

[0002] Household stoves are kitchen appliances that use liquefied petroleum gas, natural gas, coal gas and other gas fuels for direct combustion and heating. During the combustion and heating process, a large amount of heat is lost to the external environment, resulting in low combustion efficiency of the stove. Utility Model Content

[0003] The main purpose of the present application is to provide a pot rack and a stove that can achieve efficient combustion.

[0004] To achieve the above-mentioned purpose, the present application proposes a pot rack, comprising a pot rack body and at least one circle of bottom spoilers, the pot rack body is annular; multiple groups of bottom spoilers in each circle are protrudingly arranged at the bottom of the pot rack body and arranged at intervals along the circumference of the bottom, the bottom spoilers include a first bottom spoiler and a second bottom spoiler, the first bottom spoiler and the second bottom spoiler are both inclined to the radial arrangement of the pot rack body; in any group of bottom spoilers, the first bottom spoiler and the second bottom spoiler are arranged at an angle and at intervals, and in the direction of the radial direction and toward the central axis of the pot rack body, the spacing between the first bottom spoiler and the second bottom spoiler gradually increases. By protruding from the bottom of the pot rack body to form multiple groups of bottom spoilers, the thermal contact area between the secondary air and the bottom of the pot rack body is increased; at the same time, when the secondary air passes through the eight-shaped bottom spoiler, a vortex is formed, which disturbs the air at the bottom of the pot rack, achieves a better heat exchange effect and more heat recovery, and can fully preheat the intake air at the bottom, thereby improving the combustion efficiency.

[0005] Preferably, a spoiler channel is formed between the first bottom spoiler and the second bottom spoiler, and the spoiler channel faces the central axis. When the secondary air flows through the spoiler channel, a vortex of disturbed air is formed in the spoiler channel, which can fully heat the intake air at the bottom and improve the combustion efficiency of the stove.

[0006] Preferably, the bottom spoiler has multiple circles, and the bottom spoilers of two adjacent circles correspond to each other, and the spoiler channels of the corresponding bottom spoilers are aligned. By aligning the heat recovery channels, the air at the bottom of the pot rack can be better disturbed.

[0007] Preferably, the bottom comprises an annular first surface and an annular second bottom surface, the second bottom surface surrounds the first bottom surface, the first bottom surface is a plane, the first bottom surface is protruding with at least one circle of the bottom spoiler, and the second bottom surface is a curved surface, the second bottom surface is protruding with at least another circle of the bottom spoiler. By providing multiple circles of bottom spoilers, the airflow can be better disturbed and the heat exchange effect is better than providing only one circle of bottom spoilers.

[0008] Preferably, the bottom spoiler located on the first bottom surface has a first length along the airflow direction, and the bottom spoiler located on the second bottom surface has a second length along the airflow direction, and the second length is greater than the first length. When the surface area of ​​the second bottom surface is greater than the surface area of ​​the first bottom surface, the length of the bottom spoiler provided on the second bottom surface is greater than the length of the bottom spoiler provided on the first bottom surface.

[0009] Preferably, among the bottom spoilers located on the first bottom surface, the first bottom spoilers and the second bottom spoilers arranged in a group have a first spacing along the circumference of the pot rack body; among the bottom spoilers located on the second bottom surface, the first bottom spoilers and the second bottom spoilers arranged in a group have a second spacing along the circumference of the pot rack body, and the second spacing is greater than the first spacing. Since the second spacing can be greater than the first spacing, the bottom spoiler on the second bottom surface can be aligned with the bottom spoiler on the first bottom surface, so that the spoiler effect is better.

[0010] Preferably, among the bottom spoilers located in the same circle, each of the first bottom spoilers and each of the second bottom spoilers are arranged in a spiral shape. By arranging the first bottom spoilers and the second bottom spoilers in a spiral shape, the intake path of the secondary air can be increased, the heat exchange area can be increased, and the heat exchange effect can be improved.

[0011] Preferably, in any group of the bottom spoilers, the first bottom spoiler and the second bottom spoiler are in an arc shape, and in the radial direction of the pot rack body and in the direction toward the central axis, the first bottom spoiler and the second bottom spoiler are opened in an arc shape, so that the distance between the first bottom spoiler and the second bottom spoiler gradually increases from the outside to the inside.

[0012] Preferably, in any group of the bottom spoilers, in the circumferential direction of the bottom, the first bottom spoiler has a first left wall surface and a first right wall surface disposed in opposite directions, the second bottom spoiler has a second left wall surface and a second right wall surface disposed in opposite directions, the first right wall surface faces the second left wall surface and forms the angle with the second left wall surface, and the plane where the first left wall surface is located, the plane where the first right wall surface is located, the plane where the second left wall surface is located, and the plane where the second right wall surface is located are all spaced from the central axis. By spacing each wall surface from the central axis of the pot rack body, the radial inclination of each bottom spoiler relative to the pot rack body is achieved.

[0013] Preferably, the protruding heights of the first bottom spoiler and the second bottom spoiler are both less than or equal to 15 mm. This height range is convenient for forming vortices.

[0014] Preferably, in any group of the bottom spoilers, the angle between the first bottom spoiler and the second bottom spoiler is greater than or equal to 5 degrees and less than or equal to 55 degrees. This angle range facilitates the formation of vortices.

[0015] Preferably, the pot rack further comprises pot feet and support legs, wherein the pot feet are arranged on the top of the pot rack body and used to support the pot, and the support legs are arranged on the bottom of the pot rack body and used to support the pot rack body. By arranging the pot feet and support legs, an effective supporting effect can be achieved.

[0016] The present application also provides a stove, comprising the burner and the pot rack, wherein the pot rack is arranged above the burner.

[0017] Based on the pot rack and stove of the embodiment of the present application, by protruding from the bottom of the pot rack body to form multiple groups of bottom spoilers, the thermal contact area between the secondary air and the bottom of the pot rack body is increased; at the same time, when the secondary air passes through the figure-eight bottom spoiler, a vortex is formed, which disturbs the air at the bottom of the pot rack, achieving a better heat exchange effect and more heat recovery, thereby being able to fully preheat the intake air at the bottom, thereby improving the combustion efficiency of the stove.

[0032] The present application provides a pot rack, a burner and a gas stove.

[0033] like Figures 1 to 5 As shown, in order to improve the combustion efficiency, an embodiment of the present application provides a pot rack 100 , which is applied to a stove. The pot rack 100 includes a ring-shaped pot rack body 10 and a bottom spoiler 11 .

[0034] Specifically, the pot support body 10 can separate the high-temperature flame from the external environment, reduce the influence of the external low-temperature airflow on the flame and reduce the loss of combustion heat, and at the same time, can allow the hot gas to stay at the bottom 102 of the pot support body 10 for a longer time, thereby improving the combustion efficiency. The pot support body 10 is annular, and has a central axis Z, which can be perpendicular to the horizontal plane. The bottom spoiler 11 has at least one circle, and each circle has multiple groups of bottom spoilers 11. In each circle, each group of bottom spoilers 11 is protrudingly arranged on the bottom 102 of the pot support body 10, and each group of bottom spoilers 11 is arranged at intervals along the circumference of the bottom 102. Each group of bottom spoilers 11 includes a first bottom spoiler 111 and a second bottom spoiler 112 arranged at intervals. The first bottom spoiler 111 and the second bottom spoiler 112 are both arranged obliquely to the radial direction D of the pot rack body 10. There is an angle between the first bottom spoiler 111 and the second bottom spoiler 112. The first bottom spoiler 111 has a first inner end 1111 close to the central axis Z of the pot rack body 10 and a first outer end 1112 away from the central axis Z of the pot rack body 10. The second bottom spoiler 112 has a second inner end 1121 close to the central axis Z of the pot rack body 10 and a second outer end 1122 away from the central axis Z of the pot rack body 10. For any group of bottom spoilers 11, in the radial direction D of the pot rack body 10 and in the direction toward the central axis Z of the pot rack body 10, the spacing between the first bottom spoiler 111 and the second bottom spoiler 112 gradually increases, the first outer end 1112 and the second outer end 1122 converge toward each other, and the first inner end 1111 and the second outer end 1121 open away from each other, so that the bottom spoiler 11 is in an inwardly opened eight-shaped shape.

[0035] For any group of bottom spoilers 11, an outer opening 113 is formed between the first outer end 1112 and the second outer end 1122, and an inner opening 114 is formed between the first inner end 1111 and the second outer end 1121. The diameter of the outer opening 113 is smaller than that of the inner opening 114, and the inner opening 114 can face the central axis Z of the pot rack body 10.

[0036] The pot support body 10 has an annular top 101 facing the pot and an annular bottom 102 facing the cooker panel, and a combustion chamber is formed by penetrating up and down along the axis Z direction, so that the pot support body 10 is annular. The top 101 of the pot support body 10 surrounds the combustion area. The bottom 102 of the pot support body 10 can be protruding with one or more circles of bottom spoilers 11, and each circle has multiple groups of bottom spoilers 11 arranged at intervals along the circumference of the bottom 102; when there are multiple circles of bottom spoilers 11, the positive projections of all bottom spoilers 11 on the projection plane are distributed on multiple circumferences with different diameters, and the projection plane can be parallel to the horizontal plane, and the circumferences can be concentric, and the center of the circle can be located on the axis Z of the pot support body 10.

[0037] For any circle of bottom spoilers 11, the first bottom spoilers 111 and the second bottom spoilers 112 are alternately distributed in the circumferential direction of the bottom 102, and any first bottom spoiler 111 is located between two adjacent second bottom spoilers 112, and any second bottom spoiler 112 is located between two adjacent first bottom spoilers 111. For any bottom spoiler 11, a spoiler channel 115 is formed between the first bottom spoiler 111 and the second bottom spoiler 112, and the spoiler channel 115 faces the central axis Z of the pot support body 10, the outer opening 113 is the inlet of the spoiler channel 115, and the inner opening 114 is the outlet of the spoiler channel 115. When the secondary air flows into the combustion area along the radial direction D of the pot support body 10 through the spoiler channel 115, it can be heated by the first bottom spoiler 111 and the second bottom spoiler 112, and the heat on the first bottom spoiler 111 and the second bottom spoiler 112 can be brought back to the combustion area to improve the combustion efficiency.

[0038] In the illustrated embodiment, a plurality of groups of figure-eight-shaped bottom spoilers 11 are protruded from the bottom 102 of the pot rack body 10, thereby increasing the thermal contact area between the secondary air and the bottom of the pot rack body 10; at the same time, when the secondary air passes through the bottom spoiler 11, a pressure difference is formed between the outer side and the inner side of the figure-eight-shaped bottom spoiler 11, and the secondary air will go from the outer side to the inner spoiler channel 115 to form a vortex that can enhance the air disturbance, thereby achieving a better heat exchange effect and more heat recovery during the air intake process at the bottom of the pot rack body 10, thereby being able to fully preheat the intake air at the bottom and improve the combustion efficiency of the stove.

[0039] In the illustrated embodiment, for any circle of bottom spoilers 11, in the circumferential direction of the bottom 102 of the pot rack body 10, two adjacent groups of bottom spoilers 11 are spaced apart to form a spacing space 116. For example, a distance of one group of bottom spoilers 11 may be spaced apart; in the radial direction D of the pot rack body 10 and in the direction toward the central axis Z of the pot rack body 10, the spacing between the second bottom spoiler 112 and the first bottom spoiler 111 may gradually increase, the second outer end 1122 of the second bottom spoiler 112 and the first outer end 1112 of the first bottom spoiler 111 open away from each other, the second inner end 1121 of the second bottom spoiler 112 and the first inner end 1111 of the first bottom spoiler 111 gather toward each other, so that the second bottom spoiler 112 and the first bottom spoiler 111 are in an inverted figure eight shape.

[0040] In some embodiments, Figure 3 , Figure 4 and Figure 5As shown, the bottom 102 of the pot rack body 10 may be protrudingly provided with multiple circles of bottom spoilers 11. For each circle of bottom spoilers 11, the first bottom spoilers 111 and the second bottom spoilers 112 may be alternately distributed in the circumferential direction of the bottom 102. For example, the bottom 102 of the pot rack body 10 may be provided with two, three or more circles of bottom spoilers 11. By providing multiple circles of bottom spoilers 11 at the bottom 102 of the pot rack body 10, compared with providing only one circle of bottom spoilers 11, the airflow can be better disturbed and the heat exchange effect is better.

[0041] In the illustrated embodiment, each circle has multiple groups of bottom spoilers 11, and the bottom spoilers 11 of different circles are arranged one by one. For any group of bottom spoilers 11, its first bottom spoiler 111 and the second bottom spoiler 112 can be located on both sides of a vertical plane, and the vertical plane can pass through the central axis Z of the pot rack body 10; for the bottom spoilers 11 of other circles corresponding to the group of bottom spoilers 11, its first bottom spoiler 111 and the second bottom spoiler 112 can also be located on both sides of the vertical plane, so that the corresponding groups of bottom spoilers 11 are arranged in alignment. In the radial direction D of the pot support body 10, the side close to the central axis Z is the inner side, and the side away from the central axis Z is the outer side. In two adjacent circles, the bottom spoiler 11 of the outer circle is aligned with the bottom spoiler 11 of the inner circle, and the spoiler channel 115 of the bottom spoiler 11 of the outer circle can be aligned with the spoiler channel 115 of the bottom spoiler 11 of the inner circle, so as to facilitate the secondary air to flow into the combustion area and improve the air disturbance effect. In some alternative structures, the bottom spoiler 11 located in the inner circle can also be staggered with the bottom spoiler 11 located in the outer circle.

[0042] In some embodiments, Figure 3 , Figure 4 and Figure 5As shown, the bottom 102 of the pot rack body 10 may include an annular first bottom surface 1021 and an annular second bottom surface 1022, the first bottom surface 1021 may be a plane, the second bottom surface 1022 may be a curved surface, the orthographic projections of the first bottom surface 1021 and the second bottom surface 1022 on the projection plane may both be circular, the projection plane is perpendicular to the central axis Z of the pot rack body 10, and the second bottom surface 1022 may surround the first bottom surface 1021. The first bottom surface 1021 is protrudingly provided with one or more circles of bottom spoilers 11, and for each circle of bottom spoilers 11, the first bottom spoilers 111 and the second bottom spoilers 112 are alternately distributed on the circumference of the first bottom plane 111. The second bottom surface 1022 is protrudingly provided with one or more circles of bottom spoilers 11, and for each circle of bottom spoilers 11, the first bottom spoilers 111 and the second bottom spoilers 112 are alternately distributed on the circumference of the second bottom surface 1022. The bottom spoiler 11 located on the first bottom surface 1021 and the bottom spoiler 11 located on the second bottom surface 1022 may be arranged one by one. The spoiler channel 115 located on the first bottom surface 1021 and the spoiler channel 115 located on the second bottom surface 1022 may be arranged one by one.

[0043] In the illustrated embodiment, the first bottom surface 1021 and the second bottom surface 1022 may both be protruded with a circle of bottom spoilers 11. The bottom spoilers 11 of the first bottom surface 1021 and the bottom spoilers 11 of the second bottom surface 1022 may be arranged one by one in alignment, the inner opening 114 of the bottom spoiler 11 provided on the second bottom surface 1022 may face the corresponding bottom spoiler 11 provided on the first bottom surface 1021, and the inner opening 114 of the bottom spoiler 11 provided on the first bottom surface 1021 may both face the central axis Z of the pot rack body 10. Typically, since the surface area of ​​the first bottom surface 1021 is smaller than that of the second bottom surface 1022, the size of the bottom spoiler 11 provided on the first bottom surface 1021 may be smaller than the size of the bottom spoiler 11 provided on the second bottom surface 1022, so that the diameter of the inner opening 114 of the bottom spoiler 11 provided on the second bottom surface 1022 may be larger than the diameter of the inner opening 114 of the bottom spoiler 11 provided on the first bottom surface 1021, and the diameter of the outer opening 113 of the bottom spoiler 11 provided on the second bottom surface 1022 may be larger than the diameter of the outer opening 113 of the bottom spoiler 11 provided on the first bottom surface 1021.

[0044] In the illustrated embodiment, the bottom spoiler 111 located on the first bottom surface 1021 has a first length along the secondary air flow direction, and the bottom spoiler 11 located on the second bottom surface 1022 has a second length along the air flow direction, and the second length may be greater than the first length. Among the bottom spoilers 11 located on the first bottom surface 1021, the first bottom spoilers 111 and the second bottom spoilers 112 arranged in a group have a first spacing along the circumference of the pot rack body 10; among the bottom spoilers 11 located on the second bottom surface 1022, the first bottom spoilers 111 and the second bottom spoilers 112 arranged in a group have a second spacing along the circumference of the pot rack body 10, and the second spacing may be greater than the first spacing.

[0045] In some alternative structures, the bottom spoiler 11 may be entirely disposed on the first bottom surface 1021, or the bottom spoiler 11 may be entirely disposed on the second bottom surface 1022. In other alternative structures, the bottom 102 of the pot rack body 10 may only include a curved surface, and each circle of the bottom spoiler 11 is disposed on the bottom 102 of the pot rack body 10.

[0046] In some embodiments, the size of the first bottom spoiler 111 and the second bottom spoiler 112 in the circumferential direction of the bottom 102 of the pot rack body 10 is thickness; the size of the first bottom spoiler 111 and the second bottom spoiler 112 protruding from the bottom 102 of the pot rack body 10 is height; the size of the first bottom spoiler 111 and the second bottom spoiler 112 in the radial direction D of the pot rack body 10 is length. In order to enhance the spoiler effect, the thickness of the first bottom spoiler 111 and the second bottom spoiler 112 is as thin as possible while ensuring that the user is not scratched by the sharpness. In order to form a vortex, the height of the first bottom spoiler 111 and the second bottom spoiler 112 is less than or equal to 15 mm, for example, the height is 15 mm, 11 mm, 8 mm or 3 mm. The angle formed by the first bottom spoiler 111 and the second bottom spoiler 112 is greater than or equal to 5 degrees and less than or equal to 55 degrees. An angle less than 5 degrees or an angle greater than 55 degrees is not conducive to the formation of vortices. For example, the angle is 5 degrees, 12 degrees, 18 degrees, 115 degrees, 33 degrees, 40 degrees or 55 degrees.

[0047] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the first bottom spoiler 111 and the second bottom spoiler 112 are block-shaped. In the circumferential direction of the bottom 102 of the pot rack body 10, the first bottom spoiler 111 has a first left wall surface 1113 and a first right wall surface 1114 that are arranged opposite to each other, the first right wall surface 1114 faces the second bottom spoiler 112 of the same group, and the first left wall surface 1113 faces the second bottom spoiler 112 of the adjacent group, and the plane where the first left wall surface 1113 and the plane where the first right wall surface 1114 are located may not pass through the central axis of the pot rack body 10, so that the first bottom spoiler 111 can be arranged to be inclined to the radial direction D of the pot rack body 10. In the circumferential direction of the bottom 102 of the pot support body 10, the second bottom spoiler 112 has a second left wall surface 1123 facing the first bottom spoiler 111 of the same group and a second right wall surface 1124 facing the first bottom spoiler 111 of the adjacent group, and the plane where the second left wall surface 1123 and the plane where the second right wall surface 1124 are located may not pass through the central axis Z of the pot support body 10, so that the second bottom spoiler 112 can be arranged inclined to the radial direction D of the pot support body 10. For any group of bottom spoilers 11, the angle between the first bottom spoiler 111 and the second bottom spoiler 112 is the angle between the plane where the first right wall surface 1114 is located and the plane where the second left wall surface 1123 is located. In some alternative structures, in any group of bottom spoilers 11, the first bottom spoiler 111 and the second bottom spoiler 112 can be arc-shaped, and in the radial direction D of the pot rack body 10 and in the direction toward the central axis Z, the first bottom spoiler 111 and the second bottom spoiler 112 are opened in an arc shape, so that the distance between the first bottom spoiler 111 and the second bottom spoiler 112 can gradually increase from the outside to the inside.

[0048] In the illustrated embodiment, the first bottom spoiler 111 may be a trapezoidal body, a rectangular body, or a triangular prism, etc., and the shape thereof is not limited.

[0049] In the illustrated embodiment, for any circle of bottom spoilers 11, each of the first bottom spoilers 111 is arranged obliquely to the radial direction D of the pot rack body 10, and the inclination angles of each first bottom spoiler 111 can be different, so that the first bottom spoilers 111 of the circle can be arranged in a similar spiral shape as a whole. For any circle of bottom spoilers 11, each of the second bottom spoilers 112 is arranged obliquely to the radial direction D of the pot rack body 10, and the inclination angles of each second bottom spoiler 112 can be different, so that the second bottom spoilers 112 of the circle can be arranged in a similar spiral shape as a whole. The first bottom spoilers 111 and the second bottom spoilers 112 of each circle are arranged in a spiral shape, which can increase the intake path of the secondary air and increase the heat exchange area, thereby improving the heat exchange effect.

[0050] In some embodiments, Figure 1 and Figure 2As shown, the pot rack 1 further includes a plurality of pot legs 50, which are disposed on the top 101 of the pot rack body 10 and are arranged at intervals along the circumference of the top 101. The top end surface of the pot legs 50 may be parallel to the horizontal plane, so that the contact area with the bottom surface of the pot can be increased, and the pot legs 50 and the pot can be prevented from moving and slipping, so that the pot can be more firmly supported on the pot legs 50. Four pot legs 50 may be arranged at intervals along the circumference of the top 101 of the support body 1, and the pot legs 50 are in the shape of a flat plate. The number of the pot legs 50 may also be three, five or other numbers, and the shape of the pot legs 50 may also be a V-shaped plate, an I-shaped plate or other regular and irregular shapes.

[0051] In the illustrated embodiment, the pot rack 1 further comprises a plurality of supporting legs 60, which are disposed on the bottom 102 of the pot rack body 10 and are arranged at intervals along the circumference of the bottom 102. When the bottom 102 of the pot rack body 10 comprises a first bottom surface 1021 which is a plane, the plane facilitates the installation of the supporting legs 60. The bottom end surface of the supporting leg 60 may be parallel to the horizontal plane, so that the pot rack 100 can be more firmly supported on the cooker panel. The bottom 102 of the pot rack body 10 may be provided with four supporting legs 60 at intervals along the circumference, and the supporting legs 60 are in the shape of a flat plate.
