Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

With the development of society, a gas stove becomes a necessary kitchen utensil in life, and as shown in fig. 1, a gas stove in the prior art is additionally provided with an energy collecting ring 10 to collect heat during combustion, so that the combustion efficiency is improved, and the energy consumption is reduced. However, when the energy concentrating ring 10 is added to the outside of the gas range, the energy concentrating ring 10 isolates the outside cold air from the flame of the gas range, and thus the supply of secondary air required for flame combustion is insufficient, which may result in incomplete combustion of the gas. Fig. 2 shows a schematic perspective view of an energy-gathering ring pot holder assembly provided by an embodiment of the present application, and the energy-gathering ring pot holder assembly 100 can ensure that secondary air is sufficiently supplied, thereby facilitating sufficient contact between the secondary air and flames, improving combustion efficiency of gas, and promoting sufficient combustion of gas.

As shown in fig. 2, the energy concentrating ring wok stand assembly 100 includes: a shaped ring 10, a pot holder 20, a support ring 30 and fins 40.

As shown in fig. 2, the energy concentrating ring 10 may have a ring structure, and the whole ring may be concave downward (i.e., in the direction opposite to the Z-axis direction). When the gas burner 200 is located at the middle position of the energy collecting ring 10, the energy collecting ring 10 can collect flame to prevent heat from being dissipated, thereby improving heat efficiency. Moreover, the energy gathering ring 10 can prevent the flame from being blown out by wind and keep the flame stable and burning.

As also shown in fig. 2, a pot holder 20 is connected to the energy concentrating ring 10, and the pot holder 20 is located above (i.e., in the Z-axis direction) the energy concentrating ring 10, the pot holder 20 is used for supporting a cooking utensil (e.g., a pan, a wok, etc.), and the pot holder 20 is used for ensuring that a gap exists between the cooking utensil and the energy concentrating ring 10 so that a flame is in contact with oxygen. The connection of the pan support 20 and the energy gathering ring 10 may be a fixed connection, for example, welding, riveting, etc.; the connection between the pan support 20 and the energy gathering ring 10 can also be a detachable connection, such as a threaded connection, a key connection, a pin connection, etc., and the connection mode between the pan support 20 and the energy gathering ring 10 is not limited in the application and can be selected according to actual conditions.

It should be noted that, while the energy concentrating ring 10 has the effect of concentrating flames, since flames are wrapped inside the energy concentrating ring 10, after the cooker is placed above the energy concentrating ring 10, some carbon monoxide may be generated. To prevent this, the top of the pan support 20 can be raised a distance above the top of the energy gathering ring 10. Since the cookware is located a distance from the top of the ring 10, the flame can be in full contact with oxygen, thereby reducing the production of carbon monoxide.

Wherein, the number of the pan support 20 can be multiple. Illustratively, as shown in fig. 2, 4 pot supports 20 are uniformly arranged along the circumferential direction of the energy collecting ring 10, and the included angle formed between any two adjacent pot supports 20 is 90 °. Of course, 3 pot supports 20 may be uniformly arranged along the circumferential direction of the energy collecting ring 10, and an included angle formed between any two adjacent pot supports 20 is 120 °. Optionally, the number of the pan support frames 20 may also be 5, 6, … the specific number of the pan support frames 20 in this application is not further limited, and may be selected according to actual situations.

In addition, the support ring 30 is coaxially disposed with the power concentrating ring 10, and a mounting hole 50 is formed between the power concentrating ring 10 and the support ring 30 such that the gas burner 200 is mounted at the mounting hole 50. Fig. 3 is a schematic perspective view illustrating a gas burner mounted in a energy concentrating ring pot holder assembly according to an embodiment of the present invention, and as shown in fig. 3, the gas burner 200 is mounted at a position intermediate between the energy concentrating ring 10 and the support ring 30.

Furthermore, as shown in fig. 2, the fins 40 are located between the energy collecting ring 10 and the supporting ring 30 and connected with the energy collecting ring 10 and the supporting ring 30, so that the fins 40, the energy collecting ring 10 and the supporting ring 30 form an air duct 60, and the air duct gradually increases in radial size from inside to outside.

The air duct 60 is used for ventilation, that is, external air is introduced into the through-hole from the air duct 60 to contact the gas burner 200, thereby promoting flame combustion.

Likewise, the fin 40 may be detachably connected to the energy collecting ring 10 or may be fixedly connected thereto. The connection of the fins 40 to the support ring 30 may be either a detachable connection or a fixed connection. The application does not limit the connection mode of the fins 40 and the energy gathering ring 10 and the connection mode of the fins 40 and the support ring 30.

The utility model provides an it encircles pot frame subassembly 100 to gather can encircle 10 and connect the pot support 20 on gathering can ring 10 including gathering can, should gather can keep apart the outside cold air with the flame of gas-cooker by ring 10, and the heat gathering when making the gas combustion gets up, and flame is more concentrated, improves combustion efficiency. The pan support 20 is used to support the cookware and ensure that there is a gap between the cookware and the ring 10 to allow the flame to contact oxygen. The energy concentrating ring wok stand assembly 100 further comprises: the fin 40 and the support ring 30, the fin 40 is located below the energy gathering ring 10 and connected with the energy gathering ring 10, and the support ring 30 is arranged below the fin 40, so that the fin 40, the energy gathering ring 10 and the support ring 30 form an air duct 60, and the size of the air duct 60 is gradually increased from inside to outside in the radial direction. It will be appreciated that the air path 60 formed by the increasing inner to outer radial dimension is a venturi-like air path. And when wind blows over the obstacle in the air duct 60 (namely, along the position with smaller radial dimension in the air duct 60 in the air inlet direction), the air pressure near the upper port of the lee side of the obstacle (namely, along the air inlet direction, the side with gradually increased radial dimension in the air duct 60) is relatively lower, thereby generating the adsorption action and accelerating the flow rate of air, thereby increasing the suction of secondary air, ensuring that the secondary air required by flame combustion is sufficiently supplied, being beneficial to the sufficient contact of the secondary air and flame, improving the combustion efficiency of the gas stove and promoting the sufficient combustion.

It will be appreciated that in some embodiments, the concentrator ring wok stand assembly 100 is provided with a plurality of air ducts 60, the concentrator ring wok stand assembly 100 comprising: the fins 40 are all positioned between the energy gathering ring 10 and the support ring 30 and are arranged at intervals along the circumferential direction of the energy gathering ring 10, so that any fin 40 in the fins 40, the adjacent fin 40, the energy gathering ring 10 and the support ring 30 form an air channel 60; any air duct is a first air duct, a second air duct is adjacent to the first air duct, and the first air duct and the second air duct are separated by fins. That is, any one of the air ducts 60 is formed by the fins 40, the adjacent fins 40, the energy concentrating ring 10, and the support ring 30, and the air ducts 60 are arranged at intervals in the circumferential direction of the energy concentrating ring 10. Thus, the number of the air ducts 60 is increased, the contact area between the external air and the gas range head 200 is increased, the secondary air and the flame can be fully contacted, and the combustion efficiency of the gas range is improved.

Wherein, a plurality of fins 40 can be evenly arranged along the circumference of the energy gathering ring 10 at intervals, so that the formed air ducts 60 can be ensured to be the same, and the energy gathering ring wok stand assembly 100 is more beautiful.

Alternatively, the number of the fins 40 may be 18, and the included angle formed between any two adjacent fins 40 is 20 °. Optionally, the number of the fins 40 may also be 16, an included angle formed between any two adjacent fins 40 is 22.5 °, and the specific number of the fins 40 is not limited in the present application.

Fig. 4 is a cross-sectional view illustrating an air duct provided in an embodiment of the present application, in some embodiments, the radial dimension of the air duct 60 gradually increases from the middle of the air duct 60 to the two sides of the air duct, that is, as shown in fig. 4, the air duct 60 includes: an air inlet section 61, an air outlet section 62 and a throat section 63. Wherein, the choke section 63 is located between the air inlet section 61 and the air outlet section 62, and the air inlet section 61 is arranged opposite to the air outlet section 62, wherein the air inlet section 61 is provided with an air inlet, the air outlet section 62 is provided with an air outlet, the air outlet faces the mounting hole 50, and the direction of the air inlet is opposite to that of the air inlet. The radial dimension of the air duct 60 gradually decreases along the direction from the air inlet section 61 to the throat section 63, and the radial dimension of the air duct 60 gradually increases along the direction from the throat section 63 to the air outlet section 61. Thus, when the wind blows through the throat section 63 in the wind channel 60, the air pressure near the upper end of the wind outlet section 62 is relatively low, so that the adsorption effect is generated, the flow rate of the air is accelerated, the suction of secondary air is increased, the secondary air required by flame combustion is sufficiently supplied, and the sufficient contact between the secondary air and the flame is facilitated.

It should be understood that in other embodiments, the air duct 60 gradually increases in radial size from the side of the air duct 60 close to the mounting hole 50 to the side of the air duct 60 far from the mounting hole 50, that is, as shown in fig. 5, the air duct 60 includes: an air inlet section 61 and a throat section 63, and the air outlet section 62 is formed in the gas burner 200 after the gas burner 200 is mounted in the mounting hole 50. That is, as shown in fig. 5, the air outlet section 62 may also be located in the gas burner 200, and after the gas burner 200 is installed in the installation hole 50, the air outlet section is communicated with the throat section 63 to form a venturi-shaped air duct 60. Thus, when the wind blows through the throat section 63 in the wind channel 60, the air pressure near the upper end of the wind outlet section 62 of the gas burner 200 is relatively low, so as to generate an adsorption effect and accelerate the flow velocity of the air, thereby increasing the suction of the secondary air.

Fig. 6 and 7 are schematic cross-sectional views illustrating a pot holder with a shaped ring according to an embodiment of the present disclosure, where fig. 7 is a partially enlarged view of fig. 6, in some embodiments, as shown in fig. 6 and 7, a first protrusion 31 is disposed on the support ring 30, the first protrusion 31 protrudes toward the shaped ring 10, the shaped ring 10 is disposed with a second protrusion 11, the second protrusion 11 protrudes toward the support ring 30, so that the air duct 60 includes an air inlet section 61, an air outlet section 62 and a throat section 63, and a radial dimension of the air duct 60 gradually decreases in a direction from the air inlet section 61 to the throat section 63, and a radial dimension of the air duct 60 gradually increases in a direction from the throat section 63 to the air outlet section 61. That is, the wind tunnel 60 is formed in a venturi shape by making the second protrusions 11 of the power concentrating ring 10 protrude toward the support ring 30, and the first protrusions 31 of the support ring 30 protrude toward the power concentrating ring 10.

It can be understood that, when the energy collecting ring 10 is in a normal state, the second protruding portions 11 exist in the energy collecting ring 10, and therefore, when the venturi-shaped air duct 60 is processed, only the first protruding portions 31 need to be arranged on the supporting ring 30, so that the production and processing are convenient, and materials are saved.

In other embodiments, a first protrusion 31 is disposed on a first fin, a second protrusion 11 is disposed on a second fin adjacent to the first fin, the first protrusion 31 of the first fin faces the second fin, and the second protrusion 11 of the second fin faces the first fin, so that the air duct 60 includes an air inlet section 61, an air outlet section 62, and a throat section 63, and the radial dimension of the air duct 60 gradually decreases along the direction from the air inlet section 61 to the throat section 63, and the radial dimension of the air duct 60 gradually increases along the direction from the throat section 63 to the air outlet section 62. The first fin is any one of the plurality of fins, and the second fin is any one of two adjacent fins of the first fin.

Three wall surfaces are present in the air duct 60. Namely, the wall surface of the fin 40 in the air duct 60, the wall surface of the energy concentrating ring 10 in the air duct 60, and the wall surface of the support ring 30 in the air duct 60, the protrusion 70 is provided on at least one of the three wall surfaces.

Optionally, the first protruding portion and the second protruding portion are disposed opposite to each other, that is, centers of the first protruding portion and the second protruding portion are symmetrically disposed on wall surfaces of two sides of the first fin. In this way, the first and second projections are in the same position on the fins 40, improving the aesthetic appeal of the energy concentrating ring wok stand assembly 100.

In addition, in order to further improve the heat exchange effect between the secondary air and the fins 40, in some embodiments, the protrusion 70 is connected to the wall surface of the fin 40, and the radial dimension of the protrusion 70 on the side close to the fins 40 is larger than the radial dimension of the protrusion 70 on the side away from the fins 40, and the radial dimension of the protrusion 70 is gradually reduced from the side close to the fins 40 to the side away from the fins 40, so that the connection part of the protrusion 70 and the fins 40 is in a chamfered shape. Therefore, the heat exchange area between the secondary air and the fins 40 is increased, the connection area between the protruding part 70 and the fins 40 is increased, heat on the energy gathering ring 10 is transferred to the protruding part 70, the temperature of the protruding part 70 is increased, the preheating effect of the secondary air is enhanced, the enthalpy value of the secondary air entering a combustion system is increased, and the combustion efficiency of the gas cooking range 200 is improved.

The chamfer at the connection between the protruding portion 70 and the fin 40 may be an inner chamfer, and optionally, the chamfer may also be an outer chamfer, which is not limited in this application.

In a second aspect, an embodiment of the present application further provides a gas stove, and fig. 15 shows a schematic structural diagram of the gas stove provided in the embodiment of the present application, and as shown in fig. 15, the gas stove 300 can ensure that secondary air is sufficiently supplied, and the secondary air can sufficiently contact with flame, so as to improve the combustion efficiency of the gas stove 300 and promote sufficient combustion. This gas-cooker 300 includes: a gas burner 200 and a focused ring wok stand assembly 100.

Wherein, the gas burner 200 is communicated with a gas pipeline for generating flame, and the energy gathering ring pot holder assembly 100 can be described with reference to the above first aspect, which is not repeated herein.

The gas range 300 provided by the embodiment of the application comprises: a gas burner 200 and a concentrator ring pot holder assembly 20. The energy gathering ring pot holder assembly 100 comprises an energy gathering ring 10 and a pot support 20 connected to the energy gathering ring 10, and the energy gathering ring 10 can isolate external cold air from flame of the gas stove 300, so that heat generated during combustion of gas is gathered, the flame is more concentrated, and the combustion efficiency is improved. The pan support 20 is used to support the cookware and ensure that there is a gap between the cookware and the ring 10 to allow the flame to contact oxygen. The energy concentrating ring wok stand assembly 100 further comprises: the fin 40 and the support ring 30, the fin 40 is located below the energy gathering ring 10 and connected with the energy gathering ring 10, and the support ring 30 is arranged below the fin 40, so that the fin 40, the energy gathering ring 10 and the support ring 30 form an air duct 60, and the size of the air duct 60 is gradually increased from inside to outside in the radial direction. It will be appreciated that the air path 60 formed by the increasing inner to outer radial dimension is a venturi-like air path. And when the wind blows through the obstacle in the wind channel 60 (i.e. along the position that the radial dimension is less in the wind channel 60 of the air inlet direction), the air pressure near the port above the leeward side of the obstacle (i.e. along the air inlet direction, one side that the radial dimension is gradually increased in the wind channel 60) is relatively lower, thereby producing the adsorption action and accelerating the flow rate of the air, thereby increasing the suction of the secondary air, ensuring that the secondary air required by flame combustion is sufficiently supplied, being beneficial to the full contact of the secondary air and the flame, improving the combustion efficiency of the gas stove 300, and promoting the full combustion.

Fig. 16 is a schematic cross-sectional view illustrating a gas burner according to an embodiment of the present application, wherein, as shown in fig. 16, an air duct 60 is axially oriented toward a gas burner 200; that is, the air outlet is directed toward the gas cooking range 200, so as to facilitate the combustion of the flame from the gas cooking range 200 and the contact of the secondary air from the air outlet. The gas cooking burner 200 includes: a flame holding groove 201, wherein the flame holding groove 201 is a place where a flame core (also called as a flame root) is contacted when the gas range 300 is burning. The axial extension of the air duct 60 is 1.5mm-2.5mm below the flame cap flame holding groove 201, wherein the distance from the uppermost portion of the flame cap flame holding groove 201 to the throat section 63 in the vertical direction (Y-axis direction) is 1.5mm-2.5mm as shown in fig. 16. Thus, the secondary air can be supplemented to the root of the flame, and the full combustion of the gas is promoted.
