Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to the technical field of pot supports and gas cookers in kitchen appliances. Background Art

[0002] The air required for combustion in existing gas stoves is divided into primary air and secondary air. Primary air refers to the air mixed with the gas entering the stove from the air intake pipe, and secondary air refers to a part of the air that comes into contact with the flame around the burner cap and is naturally entrained. In order to improve the thermal efficiency of gas stoves, some pot supports equipped with energy-gathering rings have appeared in recent years to improve the thermal efficiency of gas stoves. However, the existing energy-gathering rings do not fully consider whether the gas can be burned efficiently.

[0003] At the same time, users may encounter problems such as overflowing pots or liquid splashing during cooking, and need to frequently clean the pot support and the gas cooker. The common energy-gathering rings on the market currently have complex structures and are not easy to clean. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pot support and a gas cooker in order to overcome the defects in the prior art that the energy-gathering ring does not fully consider whether the gas can be efficiently burned and the energy-gathering ring is not easy to clean.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A pot support, the pot support comprising an angle piece and an energy gathering ring, wherein a plurality of the angle pieces are arranged at intervals along the circumference of the pot support, the energy gathering ring is connected to the inner circumference of the angle piece, the energy gathering ring is a hollow structure, comprising an outer ring and an inner ring, the outer ring having an arc structure protruding toward the outer circumference, the inner ring comprising a first inclined surface and a second inclined surface, the first inclined surface being located above the second inclined surface, and along the radial direction of the energy gathering ring, the first inclined surface extends downward, and the second inclined surface extends upward.

[0007] In this solution, through the above-mentioned setting, the first inclined surface can reflect heat to the bottom of the pot and increase the temperature of the bottom of the pot. The second inclined surface can increase the number of times the secondary air collides with the side wall of the burner fire cover, enhance the wall-attached airflow turbulence, and form multiple local vortex areas. At the same time, the second inclined surface has a gathering effect, which makes the secondary air not easy to lose and increases the suspension time of the secondary air. As the gas continues to burn, local small vortices gradually accumulate to form multiple longitudinal annular vortex areas. After being heated at high temperature, the suspended secondary air can burn better and improve the combustion efficiency. There is a temperature difference in the longitudinal annular vortex area, and the low-temperature secondary air flows to the high-temperature secondary air, which increases the air replacement rate. As the heat flow climbs upward, due to the change in the cross-sectional area of ​​the airflow, the airflow velocity will be strengthened, thereby enhancing the combustion efficiency. According to the user's cleaning habits, the outer ring of the pot support is set as an arc structure protruding to the outer peripheral side, which reduces excessive angles and concave and convex shapes, making it convenient for customers to clean.

[0008] Preferably, the top of the corner piece is a first extension portion extending in the direction of the central axis of the pot support, and the first extension portion extends in a horizontal direction.

[0009] In this solution, by providing the first extension portion, it is convenient for the pot support to place a flat-bottomed pot, thereby improving the user experience of the pot support.

[0010] Preferably, the corner piece further comprises a second extension portion extending in the direction of the central axis of the pot support, and the second extension portion is connected to the inner side of the first extension portion;

[0011] In an extending direction from the outer circumference to the inner circumference of the pot support, the second extending portion extends obliquely downward.

[0012] In this solution, through the above arrangement, the second extension portion is suitable for mounting round-bottomed pots, thereby improving the user experience of the pot support.

[0013] Preferably, in a radial cross section of the pot support, an angle between the second extension portion and the first inclined surface is ±5°.

[0014] In this solution, when the gas cooker burns, the gas will be discharged from the fire outlet along with the flame, and a ring flame will be formed after ignition. The inclination direction of the second extension part is tangent to the bottom of the pot, so as to set up the pot. The angle difference between the first inclined surface and the second extension part is small, which is conducive to the first inclined surface reflecting heat to the bottom of the pot, increasing the temperature of the bottom of the pot, thereby ensuring that the flame is evenly distributed on the bottom of the pot during combustion, increasing the heating area, and improving the combustion efficiency.

[0015] Preferably, in a cross section along the radial direction of the pot support, the second extending portion is parallel to the first inclined surface.

[0016] Preferably, one end of the first extension portion extends to the outermost side of the corner piece, and the other end of the first extension portion extends to the inner side of the inner ring of the energy focusing ring.

[0017] In this solution, through the above arrangement, the first extension portion is suitable for mounting a variety of pots with different diameters, especially pots with smaller diameters, which is beneficial to the user experience of the pot support.

[0018] Preferably, the energy focusing ring further includes a first plane and a second plane, the first plane is flush with the top surface of the first slope and extends to the outer ring of the energy focusing ring, and the second plane is flush with the bottom surface of the second slope and extends to the outer ring of the energy focusing ring.

[0019] In this solution, by setting the first plane and the second plane, the welding area between the energy gathering ring and the corner piece can be increased, the reliability of the welding can be enhanced, the risks of false welding and desoldering can be reduced, and the stability of the pot bracket can be improved.

[0020] Preferably, the corner piece has a connecting surface on one side close to the energy gathering ring, and the connecting surface matches the shapes of the first plane, the outer ring and the second plane;

[0021] The corner piece is welded to the energy gathering ring via the connecting surface.

[0022] In this solution, by setting the connecting surface, the welding area between the energy gathering ring and the corner piece can be increased, the reliability of the welding can be enhanced, the risks of cold welding and desoldering can be reduced, and the stability of the pot bracket can be improved.

[0023] Preferably, the corner piece extends downward along the bottom of the energy focusing ring, and the bottom surface of the corner piece is used to support the energy focusing ring.

[0024] In this solution, the shape and structure of the pot support are simplified through the above-mentioned arrangement, so that the pot support is easy to clean.

[0025] A gas cooker comprises the above-mentioned pot support.

[0026] In this solution, the first inclined surface design of the pot support can reflect heat to the bottom of the pot and increase the temperature of the bottom of the pot. The second inclined surface can increase the number of times the secondary air collides with the side wall of the burner fire cover, enhance the wall-attached airflow turbulence, and form multiple local vortex areas. At the same time, the second inclined surface has a gathering effect. It makes the secondary air less likely to be lost and increases the suspension time of the secondary air. As the gas continues to burn, local small vortices gradually accumulate to form multiple longitudinal annular vortex areas. After being heated at high temperature, the suspended secondary air can burn better and improve the combustion efficiency. There is a temperature difference in the longitudinal annular vortex area, and the low-temperature secondary air flows to the high-temperature secondary air, which increases the air replacement rate. As the heat flow climbs upward, due to the change in the cross-sectional area of ​​the airflow, the airflow velocity will increase, thereby enhancing the combustion efficiency. According to the user's cleaning habits, the outer ring of the pot support is set as an arc structure protruding to the outer peripheral side, which reduces excessive angles and concave and convex shapes, making it convenient for customers to clean.

[0027] Through the above-mentioned setting, it is beneficial to increase the amount of air during combustion of the gas stove, improve the combustion efficiency of the gas stove, reduce carbon monoxide emissions, and at the same time reduce the risk of insufficient applicability of the gas stove due to increasing the primary air intake, which is beneficial to the user experience of the gas stove.

[0028] The positive and progressive effects of the utility model are: the first inclined surface design can reflect heat to the bottom of the pot and increase the temperature of the bottom of the pot. The second inclined surface can increase the number of times the secondary air collides with the side wall of the burner fire cover and enhance the turbulence of the wall-attached airflow. Multiple local vortex areas will be formed. At the same time, the second inclined surface has a gathering effect. The secondary air is not easy to lose and the secondary air suspension time is increased. As the gas continues to burn, the local small vortices gradually accumulate to form multiple longitudinal annular vortex areas. After being heated at high temperature, the suspended secondary air can burn better and improve the combustion efficiency. There is a temperature difference in the longitudinal annular vortex area, and the low-temperature secondary air flows to the high-temperature secondary air, which increases the air replacement rate. As the heat flow climbs upward, due to the change in the cross-sectional area of ​​the airflow, the airflow velocity will be strengthened, thereby enhancing the combustion efficiency. According to the user's cleaning habits, the outer ring of the pot support is set as an arc structure protruding to the outer peripheral side, which reduces excessive angles and concave and convex shapes, making it convenient for customers to clean.

The energy gathering ring 110 is a hollow structure, including an outer ring 111 and an inner ring 112. The outer ring 111 has an arc structure protruding toward the outer circumference, and the inner ring 112 includes a first inclined surface 113 and a second inclined surface 114. The first inclined surface 113 is located above the second inclined surface 114. Along the radial direction of the energy gathering ring 110, the first inclined surface 113 extends downward, and the second inclined surface 114 extends upward.

[0055] Through the above arrangement, the first inclined surface 113 can reflect heat to the bottom of the pot and increase the temperature of the bottom of the pot. The second inclined surface 114 can increase the number of collisions between the secondary air and the side wall of the burner fire cover 210 (indicated by the arrow A direction), enhance the wall airflow turbulence, and form multiple local eddy current areas, the eddy current area is B. At the same time, the second inclined surface 114 has a gathering effect, which makes the secondary air not easy to lose and increases the suspension time of the secondary air. As the gas continues to burn, the local small eddies gradually accumulate to form multiple longitudinal annular eddy current areas. After the suspended secondary air is heated at high temperature, it can be better burned and the combustion efficiency is improved. There is a temperature difference in the longitudinal annular eddy current area, and the low-temperature secondary air (indicated by the arrow C1 direction) flows to the high-temperature secondary air (indicated by the arrow C2 direction). The flow direction of the secondary air here is a ring-shaped step rise, which improves the air replacement rate. As the heat flow climbs upward, due to the change in the cross-sectional area of ​​the airflow, the airflow velocity will be strengthened, thereby enhancing the combustion efficiency. According to the cleaning habits of users, the outer ring 111 of the pot support 100 is set to an arc structure protruding toward the outer peripheral side, which reduces excessive angles and concave-convex shapes and facilitates customer cleaning.

The inclination direction of the second extension portion 122 is tangent to the bottom of the pot, so that the pot can be set up. The angle difference between the first inclined surface 113 and the second extension portion 122 is small, which is conducive to the first inclined surface 113 reflecting heat to the bottom of the pot, increasing the temperature of the bottom of the pot, thereby ensuring that the flame is evenly distributed on the bottom of the pot during combustion, increasing the heating area, and improving the combustion efficiency.

[0063] As a preferred implementation, Figure 1 As shown, in the cross section along the radial direction of the pot support 100 , the second extension portion 122 is parallel to the first inclined surface 113 .

At the same time, the shape of the corner piece 120 is simplified, which is convenient for cleaning the pot support 100.
