Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stoves, and in particular to an energy-concentrating pot rack and a stove including the same. Background Technology
[0002] With social development, gas stoves have become an essential cooking appliance in modern households, and users' demands for them are gradually increasing. How to improve the thermal efficiency of gas stoves has become an urgent problem to be solved.
[0003] In stove design, improving combustion thermal efficiency is mostly achieved by placing energy-concentrating plates. However, existing energy-concentrating plates have complex structures and poor thermal efficiency. Moreover, most energy-concentrating plates are one-piece structures, and the contact parts between the plate surface and the corner plates are not easy to clean. Long-term accumulation of liquid can cause certain damage to the pot rack. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of poor thermal efficiency, complex pot rack structure and inconvenient cleaning of existing stoves, and to provide an energy-concentrating pot rack and a stove including the same.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] An energy-concentrating pot rack includes a lower plate mounted on a stove and an upper support mounted on the lower plate. The upper support is detachably connected to the lower plate and is used to support the pot body. The upper support includes a first annular inclined surface surrounding the burner and a first plate surface located outside the first annular inclined surface. The radial edge of the first plate surface has a first rolled edge that curls downwards. The lower plate includes a second annular inclined surface surrounding the burner and a second plate surface located outside the second annular inclined surface. The second annular inclined surface is opposite to and spaced apart from the first annular inclined surface. The outer diameter of the first rolled edge is not greater than the outer diameter of the second annular inclined surface.
[0007] In this design, the energy-concentrating pot rack, through the aforementioned upper support and lower plate, forms a semi-enclosed cavity (or semi-enclosed structure) between the first annular inclined surface, the first plate surface, the first rolled edge of the upper support, and the second annular inclined surface of the lower plate. This restricts the diffusion path of hot airflow, reduces heat loss, and effectively concentrates the heat generated during combustion. This allows more heat to be transferred to the bottom of the pot through thermal radiation and convection, thereby improving thermal efficiency. The outer diameter of the first rolled edge is no larger than the outer diameter of the second annular inclined surface. The second annular inclined surface of the lower plate forms a relatively large slope, which guides the airflow, optimizes the oxygen supply path, and ensures that the burner has sufficient oxygen to participate in the combustion reaction, avoiding incomplete combustion due to insufficient oxygen. This allows the burner to release more heat during combustion, further improving thermal efficiency. Furthermore, the pot rack has a simple structure; the upper support and lower plate are detachably connected for easy cleaning, and the regularly shaped plate surface formed by the first annular inclined surface and the first plate surface of the upper support also facilitates cleaning.
[0008] Preferably, the radial edge of the second disc surface has a downwardly rolled second edge.
[0009] In this design, the lower plate also forms a semi-enclosed cavity structure through the above structure, which helps to reduce heat loss and further improve thermal efficiency.
[0010] Preferably, the bottom edge of the second rolled edge is lower than the inner edge of the second annular inclined surface near the burner.
[0011] Preferably, the energy-concentrating pot support also includes a plurality of pot support legs, each of which is detachably connected to the lower plate, or each of which is detachably connected to both the upper support and the lower plate.
[0012] In this design, the pot support legs are used to support the pot. The pot support legs are detachably connected to the lower plate, or detachably connected to both the upper support and the lower plate, which facilitates cleaning the upper support and the lower plate after disassembling the upper support and the pot support legs.
[0013] Preferably, the upper surface of the lower plate is provided with a plurality of spaced slots, and one end of each pot support leg is inserted into the slot.
[0014] In this design, the pot support legs and the slot are used to achieve a detachable connection between the pot support legs and the lower plate.
[0015] Preferably, the end of the pot support leg that connects to the upper bracket is provided with a slot that matches the top contour of the upper bracket, and the pot support leg is engaged with the upper bracket through the slot.
[0016] In this design, the pot support legs are engaged with the top contour surface of the upper support legs via slots, enabling a detachable connection between the pot support legs and the upper bracket.
[0017] Preferably, the upper surface of the lower plate is provided with four slots, which are symmetrically distributed on the upper surface of the lower plate.
[0018] In this design, the four slots ensure that the four paired pot supports are evenly stressed, which is beneficial to structural stability.
[0019] Preferably, the burner includes an inner ring flame hole and an outer ring flame hole located outside the inner ring flame hole, and the first annular inclined surface is configured such that the inclination angle of the first annular inclined surface is smaller than the inclination angle of the flame injected by the outer ring flame hole.
[0020] In this design, the inclination angle of the first annular inclined surface is smaller than the inclination angle of the flame jet from the outer annular fire hole, allowing more flame to be jetted onto the bottom surface of the pot. The flame is evenly distributed under the obstruction of the curved surface of the bottom of the pot, which is beneficial to improving heating efficiency.
[0021] Preferably, the angle between the inclination angle of the first annular inclined surface and the inclination angle of the flame ejected from the outer annular fire hole is less than 1.5°.
[0022] The above-mentioned angle design in this scheme helps to enhance the uniform distribution of the flame, avoid local overheating or uneven heat distribution, reduce flue gas generation, and further improve heating efficiency.
[0023] A cooker unit comprising the energy-concentrating pot rack as described above.
[0024] In this design, the stove utilizes the aforementioned energy-concentrating pot rack to reduce heat loss and effectively concentrate the heat generated during combustion. This allows more heat to be transferred to the bottom of the pot through thermal radiation and convection, thereby improving thermal efficiency. Furthermore, its simple structure facilitates easy cleaning.
[0025] The positive and progressive effects of this utility model are as follows: the energy-concentrating pot rack and the stove including it reduce heat loss, effectively concentrate the heat generated during combustion, and allow more heat to be transferred to the bottom of the pot through thermal radiation and thermal convection, thereby improving thermal efficiency. Furthermore, its simple structure makes it easy to clean separately. Attached Figure Description

Detailed Implementation
[0033] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.
[0034] Example 1;
[0035] This embodiment provides an energy-concentrating pot rack 100, which is placed on the countertop of the stove 300 to support pots for frying or other purposes in the kitchen.
[0036] like Figures 1-5 As shown, the energy-concentrating pot holder 100 includes a lower plate mounted on the cooktop 300 and an upper support 1 mounted on the lower plate. The upper support 1 is detachably connected to the lower plate and is used to support the pot body. The upper support 1 includes a first annular inclined surface 11 surrounding the burner 200 and a first disc surface 12 located outside the first annular inclined surface 11. The radial edge of the first disc surface 12 has a downwardly rolled first edge 13. The first annular inclined surface 11 is a large inclined surface, while the first disc surface 12 is a narrower transition disc surface, and its cross-section presents an approximately arc-shaped structure. The lower plate includes a second annular inclined surface 21 surrounding the burner 200 and a second disc surface 22 located outside the second annular inclined surface 21. The second annular inclined surface 21 is opposite to and spaced apart from the first annular inclined surface 11. The second annular inclined surface 21 is a large inclined surface, while the second disc surface 22 is a disc surface with a certain flat surface at the top. Wherein, the outer diameter of the first rolled edge 13 is not greater than the outer diameter of the second annular inclined surface 21, that is, the upper support 1 is rolled at the middle position of the inclined surface of the lower plate, rather than the first annular inclined surface 11 extending to the radial outer edge of the lower plate before being rolled.
[0037] The energy-concentrating pot rack 100, through the aforementioned upper support 1 and lower plate, forms a semi-enclosed cavity (or semi-enclosed structure) between the first annular inclined surface 11, the first plate surface 12, and the first rolled edge 13 of the upper support 1 and the second annular inclined surface 21 of the lower plate. This restricts the diffusion path of hot airflow, reduces heat loss, and effectively concentrates the heat generated during combustion, allowing more heat to be transferred to the bottom of the pot through thermal radiation and convection, thereby improving thermal efficiency. The outer diameter of the first rolled edge 13 is no larger than the outer diameter of the second annular inclined surface 21. The second annular inclined surface 21 of the lower plate forms a relatively large slope, which can guide the airflow, optimize the oxygen supply path, and ensure that the burner 200 has sufficient oxygen to participate in the combustion reaction during combustion, avoiding incomplete combustion due to insufficient oxygen. This allows the burner 200 to release more heat during combustion, further improving thermal efficiency. Furthermore, the pot rack has a simple structure; the upper support 1 and lower plate are detachably connected, facilitating separate cleaning. The first annular inclined surface 11 and the first plate surface 12 of the upper support 1 also form a regularly shaped plate surface, making cleaning easier.
[0038] Among them, such as Figure 2 As shown, the radial edge of the second disk 22 is also provided with a downward-curled second edge 23. The second edge 23 is rolled downward and inward, forming a semi-closed cavity structure, which helps to reduce heat loss and further improve thermal efficiency.
[0039] The bottom edge of the second rolled edge 23 is lower than the inner edge of the second annular inclined surface 21 near the burner 200.
[0040] Among them, such as Figures 2-4 As shown, the energy-concentrating pot rack 100 also includes several pot support legs 3. The pot support legs 3 are used to support the pot. Each pot support leg 3 is detachably connected to the lower plate, or each pot support leg 3 is detachably connected to the upper support 1 and the lower plate. This makes it easy to clean the upper support 1 and the lower plate after removing the pot support legs 3.
[0041] Specifically, in this embodiment, the upper surface of the lower plate is provided with a plurality of spaced slots 24, and one end of each pot support 3 is inserted into the slot 24. Through the cooperation between the pot support 3 and the slot 24, a detachable connection between the pot support 3 and the lower plate is achieved.
[0042] Furthermore, in this embodiment, the end of the pot support 3 connected to the upper bracket 1 is provided with a slot 31 that matches the top contour of the upper bracket 1, and the pot support 3 is engaged with the upper bracket 1 through the slot 31. The pot support 3 is engaged with the top contour surface of the upper support through the slot 31. This engagement using the arc-shaped mating surface can also play a fixing role and can also realize the detachable connection between the pot support 3 and the upper bracket 1.
[0043] In other embodiments, depending on the required connection strength, the pot support can be welded to the upper support 1 to enhance the connection strength, or other connection methods can be used.
[0044] like Figure 4 As shown, in this embodiment, the upper surface of the lower plate is provided with four slots 24, which are symmetrically distributed on the upper surface of the lower plate. These four slots 24 ensure that the four paired pot supports 3 bear the force evenly when supporting the pot, which is beneficial to structural stability.
[0045] like Figure 5 As shown, the burner 200 includes an inner ring flame hole 201 and an outer ring flame hole 202 located outside the inner ring flame hole 201. The first annular inclined surface 11 is configured such that the inclination angle of the first annular inclined surface 11 is smaller than the inclination angle of the flame injected from the outer ring flame hole 202. Because the inclination angle of the first annular inclined surface 11 is smaller than the inclination angle of the flame injected from the outer ring flame hole 202, more of the flame is injected onto the bottom surface of the pot. The flame is evenly distributed due to the obstruction of the curved surface of the pot bottom, which helps to improve heating efficiency.
[0046] Preferably, the angle between the inclination angle of the first annular inclined surface 11 and the inclination angle of the flame injected by the outer annular fire hole 202 is less than 1.5°. This angle design helps to enhance the uniform distribution of the flame, avoid local overheating or uneven heat distribution, reduce flue gas generation, and further improve heating efficiency.
[0047] Example 2;
[0048] This embodiment provides a cooktop 300, which includes a heat-concentrating pot rack 100 as described in Embodiment 1. Through the aforementioned heat-concentrating pot rack 100, the cooktop 300 reduces heat loss and effectively concentrates the heat generated during combustion, allowing more heat to be transferred to the bottom of the pot through thermal radiation and convection, thereby improving thermal efficiency. Furthermore, it has a simple structure and is easy to clean separately.
