Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to a pot support. Background Technology

[0002] The pot support of a gas stove is an important component of the product. Its core function is to provide support for the pots and cookware and ensure that secondary air enters the core combustion zone, thereby ensuring combustion efficiency. Some existing gas stoves have through holes on the pot supports that connect directly to the combustion zone. These through holes allow airflow to enter the combustion zone directly, increasing the amount of secondary air input to the combustion zone. However, during gas stove operation, heat also leaks out of the pot supports through these through holes, resulting in significant heat loss and directly affecting combustion efficiency. Summary of the Invention

[0003] This application addresses the shortcomings of existing methods by providing a pot support to solve the technical problem that, during the operation of a gas stove, heat leaks out through the through-holes to the outside of the pot support, resulting in significant heat loss and directly affecting combustion efficiency.

[0004] This application provides a pot support, which mainly includes a ring body, the outer edge of which is higher than the inner edge to enclose and form a combustion zone; the ring body has stacked and independent upper and lower cavities; the lower cavity is a closed cavity; the cavity wall of the upper cavity has an air inlet and an air outlet communicating with the inside and outside of the upper cavity to form a channel for high-temperature gas flow; the air inlet and the air outlet are arranged far apart; the air outlet faces a through hole at the bottom of the ring body.

[0005] As an optional implementation, the air inlet is located at the top of the ring body; the air outlet is located at the inner edge of the ring body.

[0006] As an optional implementation, a stepped structure is formed on the inner side of the outer edge of the ring, and the air inlet is opened on the inner side of the stepped structure.

[0007] As an alternative implementation, the air inlet includes a plurality of first holes arranged circumferentially.

[0008] As an optional implementation, the air intake further includes a plurality of second holes arranged circumferentially, the second holes having different shapes from the first holes; the first holes and the second holes are arranged alternately in sequence.

[0009] As an optional implementation, the vent includes a plurality of vent sub-vents arranged circumferentially.

[0010] As an optional implementation, the area of ​​the air inlet is larger than the area of ​​the air outlet.

[0011] As an optional implementation, the area of ​​the air inlet is greater than or equal to 2030 mm². 2 And less than or equal to 2600mm 2 ; and / or, the area of ​​the vent hole is greater than or equal to 1000 mm². 2 and less than or equal to 1500mm 2 .

[0012] As an optional implementation, the ring body further includes a ring bottom, a ring cover, and a partition; the ring cover is disposed on the ring bottom to form a cavity; the partition is ring-shaped and fixed in the cavity to divide the cavity into the upper cavity and the lower cavity, and the partition is inclined downward toward the air outlet.

[0013] As an optional implementation, the pot support also includes an anti-slip pad and multiple legs; the multiple legs are arranged circumferentially and pass through the ring; the top of each leg serves as a pot support end; the anti-slip pad is installed at the bottom of each leg.

[0014] This application provides a pot support, and the technical solution provided by the embodiments of this application has at least the following beneficial effects:

[0015] During the burner's operation, driven by the secondary air or exhaust gas from the range hood, some of the generated high-temperature gas is drawn into the upper chamber through the upper air inlet. This high-temperature gas flows along the upper chamber, and its heat is conducted through the chamber walls, significantly increasing the temperature of the entire pot support. The heated pot support directly and efficiently conducts heat to the cookware. The high-temperature gas then flows downwards and exits through the air outlet, participating in combustion and forming new high-temperature gas. This new high-temperature gas then flows upwards and is drawn into the upper chamber, thus creating a thermal cycle and significantly improving overall thermal efficiency.

[0032] This application is described in detail below.

Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted.

[0033] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, integers, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, elements, components, and / or groups thereof. The term “and / or” as used includes all or any units and all combinations thereof of one or more associated listed items.

[0034] like Figure 1-9 As shown, this application embodiment provides a pot support, which mainly includes a ring body 1, the outer edge of which is higher than the inner edge to enclose and form a combustion zone; the ring body 1 has a stacked and independent upper cavity 11 and a lower cavity 12 inside; the lower cavity 12 is a closed cavity; the cavity wall of the upper cavity 11 has an air inlet 13 and an air outlet 14 communicating with the inside and outside of the upper cavity 11 to form a channel for high-temperature gas flow; the air inlet 13 and the air outlet 14 are arranged far apart; the air outlet 14 faces the through hole at the bottom of the ring body 1.

[0035] In this embodiment, the ring 1 is horizontally positioned and vertically aligned axially. The ring 1 is funnel-shaped, with two openings of different sizes: the larger opening is at the top, and the smaller opening is at the bottom. The inner side of the ring 1 has a conical surface, serving as the combustion zone. The through-hole at the bottom of the ring 1, i.e., the smaller opening, serves as a secondary air supply port.

[0036] The upper cavity 11 of the annular body 1 is higher than the lower cavity 12. The air inlet 13 is higher than the air outlet 14. The upper cavity 11 is part of a high-temperature gas circulation. The lower cavity 12, as a closed cavity, mainly functions to store heat and form a radiant heat source.

[0037] During the burner's operation, driven by the secondary air or exhaust gas flow from the flue, some of the generated high-temperature gas is drawn into the upper chamber 11 through the upper air inlet 13. This high-temperature gas flows along the upper chamber 11, and its heat is conducted through the chamber walls, significantly increasing the temperature of the entire pot support. The heated pot support directly and efficiently conducts heat to the cookware. The high-temperature gas then flows downwards and exits through the air outlet 14, participating in combustion and forming new high-temperature gas. This new high-temperature gas then flows upwards and is drawn into the upper chamber 11, thus creating a thermal cycle and significantly improving overall thermal efficiency.

[0038] like Figure 1-6 As shown in Figure 8, as an optional implementation, the air inlet 13 is located at the top of the ring body 1; the air outlet 14 is located at the inner edge of the ring body 1.

[0039] Based on the aforementioned embodiments, in this embodiment, the air inlet 13 and air outlet 14 can be of any shape, such as square, circular, polygonal, or elliptical holes. The air inlet 13 is opened upwards or inwards, and is located near the outer edge of the ring body 1 to facilitate the intake of high-temperature gas. The air outlet 14 is directly opposite the secondary air replenishment hole, that is, directly opposite the through hole at the bottom of the ring body 1, so that the high-temperature gas can participate in combustion after being ejected.

[0040] In some embodiments, the air inlet 13 is a strip-shaped hole, and a group of multiple air inlets 13 are arranged circumferentially, with multiple groups of air inlets 13 forming a concentric circle distribution.

[0041] like Figure 5 As shown, as an optional implementation, a stepped structure is formed on the inner side of the outer edge of the ring body 1, and an air inlet 13 is opened on the inner side of the stepped structure.

[0042] Based on the aforementioned embodiments, in this embodiment, a stepped structure, i.e., a stepped drop structure, is formed at the top of the ring 1 near its outer edge. An air inlet 13 is opened on the inner wall structure of the stepped structure; the high-temperature gas rises and flows along the conical surface on the inner side of the ring 1 and flows to the stepped structure, where it can flow more concentratedly to the air inlet 13.

[0043] like Figure 6 As shown, in one optional implementation, the air intake 13 includes a plurality of first holes 131 arranged circumferentially.

[0044] Based on the aforementioned embodiments, in this embodiment, the first holes 131, whether facing upwards or inwards, are arranged circumferentially to more fully draw in high-temperature gas from multiple angles.

[0045] like Figure 6 As shown, as an optional implementation, the air intake 13 also includes a plurality of second holes 132 arranged circumferentially, the second holes 132 having different shapes from the first holes 131; the first holes 131 and the second holes 132 are arranged alternately in sequence.

[0046] Based on the aforementioned embodiments, in this embodiment, the first hole 131 is a polygonal hole, and the second hole 132 is a strip-shaped hole. The second hole 132 and the first hole 131 have different shapes to make reasonable use of space and improve overall thermal efficiency.

[0047] like Figure 1 , 3 As shown in Figures 4, 5, 6 and 8, as an optional embodiment, the vent 14 includes a plurality of vent sub-vents arranged circumferentially.

[0048] Based on the aforementioned embodiments, in this embodiment, the inner edge of the ring body 1, i.e. the wall of the through hole, has multiple air outlet holes. These multiple air outlet holes are all directly facing the secondary air flow. The high-temperature gas flowing out from the air outlet hole 14 can be directly added to the secondary air flow and participate in combustion.

[0049] As an optional implementation, the area of ​​the air inlet 13 is larger than the area of ​​the air outlet 14.

[0050] Using the above scheme, when the burner is working, the generated high-temperature gas rises. Since the total area of ​​the inlet 13 is larger than the total area of ​​the outlet 14, the flow velocity of the hot gas decreases after entering the cavity. This allows the high-temperature gas to have more sufficient residence time to exchange heat with the cavity wall, thereby maximizing the heating of the entire pot support. Subsequently, the gas flow is ejected at a higher speed from the smaller outlet 14. This high-speed gas flow can more effectively draw in the surrounding secondary air, improving the combustion state.

[0051] As an optional implementation, the area of ​​the air inlet 13 is greater than or equal to 2030 mm². 2 And less than or equal to 2600mm 2 ; and / or, the area of ​​the vent 14 is greater than or equal to 1000 mm². 2 and less than or equal to 1500mm 2 .

[0052] By adopting the above scheme, the efficiency of high-temperature gas intake and ejection can be guaranteed.

[0053] In some embodiments, the area of ​​the air inlet 13 is 2430 mm². 2 .

[0054] In some embodiments, the area of ​​the vent 14 is 1276 mm². 2 .

[0055] like Figure 3 , 7 As shown in Figures 8 and 9, as an optional embodiment, the ring body 1 further includes a ring bottom 15, a ring cover 16, and a partition 17; the ring cover 16 is disposed on the ring bottom 15 to form a cavity; the partition 17 is ring-shaped and is fixed in the cavity to divide the cavity into an upper cavity 11 and a lower cavity 12, and the partition 17 is inclined downward toward the air outlet 14.

[0056] Based on the aforementioned embodiments, in this embodiment, the inclined surface of the partition 17 guides the high-temperature gas to the lower-positioned outlet 14, reducing flow resistance, making heat circulation easier, reducing energy loss, making circulation smoother and more efficient, and further improving heat exchange efficiency.

[0057] In addition, water vapor in the high-temperature fluid will condense into droplets on the inner wall of the cavity when it cools down. The inclined partition 17 provides an outlet path for these droplets, allowing them to be smoothly discharged from the vent 14 under the influence of gravity. This greatly avoids corrosion, blockage, or odor problems that may be caused by the accumulation of condensate droplets.

[0058] like Figure 1-6As shown in Figure 10, as an optional embodiment, the pot support also includes an anti-slip pad 3 and multiple legs 2; the multiple legs 2 are arranged circumferentially and pass through the ring body 1; the top of the legs 2 serves as the pot support end; the anti-slip pad 3 is installed at the bottom of the legs 2.

[0059] Based on the aforementioned embodiments, in this embodiment, the height and distribution of the multiple support legs 2 ensure that the bottom of the cookware is kept at the optimal distance from the flame. This is to ensure the effective transfer of heat from the flame and avoid incomplete combustion or low efficiency.

[0060] Anti-slip mats are typically made of high-temperature resistant, high-friction materials such as silicone and rubber, greatly increasing the friction on the bottom. When users stir-fry or move the pot, the pot support will not slide, avoiding the danger of the pot tipping over due to the support shifting.

[0061] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0062] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
