Referring to fig. 1 and 2 together, the present application provides a gas range 1, in which the gas range 1 includes a panel (not shown), a burner 200 and a power collecting bracket 100, the power collecting bracket 100 and the burner 200 are both coupled to the panel, the power collecting bracket 100 is used for supporting a cooking utensil 300 and collecting power, and the burner 200 is used for injecting and igniting gas to heat the cooking utensil 300. It is understood that the reference to gas in this application refers to a mixed gas formed by mixing combustion gas with air.

The energy collecting bracket 100 comprises an energy collecting piece 10 and a flow disturbing component 20, wherein the energy collecting piece 10 is supported on the panel and used for supporting the cooking utensil 300 and collecting energy, and the flow disturbing component 20 is matched and connected in the energy collecting piece 10 and used for disturbing fuel gas. The inner side of the energy gathering piece 10 is provided with a premixing surface 112 and a combustion surface 114 which are connected with each other, the premixing surface 112 is configured to be capable of surrounding with the outer wall surface 310 of the cooking utensil 300 to form a premixing channel 123, the combustion surface 114 is configured to be capable of surrounding with the outer wall surface 310 of the cooking utensil 300 to form a combustion channel 125, the premixing channel 123 and the combustion channel 125 are sequentially arranged and communicated along the flowing direction of the gas (the direction indicated by the straight arrow in fig. 1), and the aperture of the premixing channel 123 is gradually reduced along the flowing direction of the gas; the flow perturbation assembly 20 is received in the combustion channel 125 and protrudes from the combustion face 114.

Specifically, the energy gathering piece 10 is a hollow structure and has an inner surface 111, the inner surface 111 is surrounded to form an energy gathering cavity 12, the energy gathering piece 10 has a first mounting port 121 close to the panel and a second mounting port 122 far away from the panel, the first mounting port 121 and the second mounting port 122 are both communicated with the energy gathering cavity 12, the burner 200 is supported on the panel, and the first mounting port 121 extends into the energy gathering cavity 12. The cooking utensil 300 is supported on the energy gathering member 10, specifically, the cooking utensil 300 is supported on the energy gathering member 10 through a support leg (not shown) arranged on the energy gathering member 10, the cooking utensil 300 is arranged through the second mounting opening 122 and at least partially accommodated in the energy gathering cavity 12, and besides, the cooking utensil 300 is also required to be arranged at a distance from the burner 200. The inner surface 111 includes a predetermined surface and a combustion surface 114 connected to each other, the predetermined surface is disposed close to the panel, and the combustion surface 114 is disposed far from the panel. The premixing surface 112 and the outer wall 310 of the cooking utensil 300 are surrounded to form a premixing passage 123, and the combustion surface 114 and the outer wall 310 of the cooking utensil 300 are surrounded to form a combustion passage 125. It is understood that if the cooking utensil 300 is spaced from the inner surface 111, the pre-mixing channel 123 and the combustion channel 125 are all closed annular channels, that is, the pre-mixing channel 123 and the combustion channel 125 are all around the cooking utensil 300 along the circumference of the cooking utensil 300. If there is a contact portion between the cooking utensil 300 and the inner surface 111, the pre-mixing channel 123 and the combustion channel 125 are both non-closed arc channels, that is, the pre-mixing channel 123 and the combustion channel 125 both extend along the circumference of the cooking utensil 300 but do not go around the cooking utensil 300. The burner 200 is used for injecting gas into the premixing passage 123, so that the gas can further mix with air in the premixing passage 123 and then flow into the combustion passage 125, and then the gas is combusted with the combustion passage 125 under the action of the burner 200.

In the conventional energy concentrating bracket 100, when the cooking utensil 300 (e.g. a pot) is supported on the energy concentrating member 10 and extends into the energy concentrating chamber 12, the diameter of the premixing passage 123 formed by the outer wall surface 310 of the cooking utensil 300 and the premixing surface 112 is unchanged in the flowing direction of the gas, and the flow disturbing assembly 20 is arranged in the combustion passage 125. In the process of the gas flowing in the premixing passage 123 and the combustion passage 125, since the gas itself has a certain viscosity and there is a frictional resistance between the gas and the outer wall surface 310 of the cooking utensil 300, a part of the gas is easily adhered to the outer wall surface 310 of the cooking utensil 300 and a thick convection layer is formed. The heat conduction coefficient of the gas is very low, so that the heat generated by combustion cannot be quickly and efficiently transferred to the bottom end of the cooking appliance 300 through the convection layer, resulting in insufficient heat conduction efficiency of the gas range 1.

According to the principle of continuous fluid flow, the flow rate into the premixing passage 123 is equal to the flow rate out of the premixing passage 123, that is, the flow rate of the fuel gas passing through each opening of the premixing passage 123 is also constant. According to the formula S₁V₁＝S₂V₂，S₁Representing the size of the area of the flow through the first flow section, V₁Representing the velocity, S, of the gas flow through the first flow section₂Representing the size of the area of the flow through the second flow section, V₂Which represents the velocity of the gas flow through the second flow section, since the bore of the premixing passage 123 is gradually reduced in the flow direction of the gas in the present application, the velocity of the gas is gradually increased as the gas flows in the premixing passage 123. Thus, the gas flowing through the premixing passage 123 can flow into the combustion passage 125 at a high speed. Further, since the baffle assembly 20 is received in the combustion channel 125 and protrudes from the combustion surface 114, the gas flowing at a high speed is agitated and switched to a turbulent state by the baffle assembly 20, and the speed direction of the gas in the turbulent state is diversified, so that the gas can continuously impact the troposphere adhered to the outer wall surface 310 of the cooking utensil 300, so that the thickness of the troposphere is reduced, and further, the heat generated by the combustion of the gas can be faster and more rapidMore to the cooking utensil 300, so that the gas range 1 and the energy collecting bracket 100 thereof have higher heat conduction efficiency.

It is understood that in the present application, the energy concentrating bracket 100 itself has a high heat conduction efficiency because the energy concentrating element 10 has a better energy concentrating effect. Due to the change of the caliber of the premixing channel 123 and the arrangement of the flow disturbing assembly 20, the energy collecting bracket 100 has higher heat conduction efficiency.

The concentrator 10 further has a diverging surface 113, the diverging surface 113 is configured to surround an outer wall surface 310 of the cooking appliance 300 to form a diverging passage 124, the diverging passage 124 communicates between the premixing passage 123 and the combustion passage 125, and an aperture of the diverging passage 124 is larger than an aperture of an opening of the premixing passage 123 communicating with the diverging passage 124. It is understood that the inner surface 111 further includes an expanding surface 113, and if the cooking utensil 300 is spaced apart from the inner surface 111, the expanding channel 124 is a closed annular channel, that is, the expanding channel 124 surrounds the cooking utensil 300 along the circumference of the cooking utensil 300. If there is a portion of the cooking utensil 300 that contacts the inner surface 111, the expanding channel 124 is formed as an unclosed arc-shaped channel, that is, the expanding channel 124 extends along the circumference of the cooking utensil 300 but does not go around the circumference of the cooking utensil 300.

It can be understood that the premix passage 123 is defined to have an input port and an output port, the fuel gas injected by the burner 200 is input into the premix passage 123 from the input port and output into the expansion passage 124 from the output port, and the aperture of the expansion passage 124 is larger than the aperture of the opening of the premix passage 123 communicating with the expansion passage 124, which means that the aperture of any one opening of the expansion passage 124 is larger than the aperture of the output port. Since the bore of the premixing passage 123 is gradually reduced in the flowing direction of the gas, the resistance to the gas is also increased, resulting in a risk of insufficient gas supply in the combustion passage 125. In the present application, by providing the expanding channel 124, after the gas is accelerated through the premixing channel 123 and flows into the expanding channel 124, since the aperture of the expanding channel 124 is larger than that of the output port, the resistance of the gas in the expanding channel 124 is small, and the expanding channel 124 is communicated with the premixing channel 123 and the combustion channel 125, so that the gas can be sufficiently input into the combustion channel 125 to be combusted and released heat under the action of the expanding channel 124. It will be appreciated that due to the effect of inertia, the gas is still able to pass through the expanding channel 124 and flow into the combustion channel 125 at a relatively high velocity in the direction of flow of the gas, provided the distance of the expanding channel 124 is appropriate.

Alternatively, the diameter of the expanding channel 124 may be constant or gradually decreased in the flowing direction of the fuel gas. In one embodiment, the bore of the expanding channel 124 gradually increases in the flow direction of the combustion gas. Therefore, the velocity of the combustion gas is gradually and weakly reduced during the process of the combustion gas flowing through the expanding channel 124, so that the expanding channel 124 has a small influence on the velocity of the combustion gas, so that the combustion gas can still flow into the combustion channel 125 at a high flow velocity and forms turbulent combustion under the disturbance of the flow disturbing assembly 20.

Further, the expanding passage 124 is in transitional communication with the premixing passage 123. In this way, in the course of the gas flowing into the combustion passage 125 through the expanding passage 124, the velocity loss of the gas is smaller, thereby enabling the gas to flow into the combustion passage 125 at a high velocity.

Referring to fig. 3, the spoiler assembly 20 includes a plurality of spoiler members 21, and the spoiler members 21 are spaced apart from each other along the circumferential direction of the energy concentrating member 10. Along a plurality of spoilers 21 that the circumference interval of gathering the piece 10 set up also set up along the circumference interval of cooking utensil 300 simultaneously, and combustion channel 125 also sets up around the circumference of cooking utensil 300, it can be seen from this that a plurality of spoilers 21 can be followed the circumference of cooking utensil 300 and carried out sufficient disturbance to the gas that flows in combustion channel 125, make the turbulence intensity who forms also bigger, thereby it can carry out turbulent combustion in combustion channel 125 to be convenient for the gas, and the gas can also powerfully strike the troposphere, in order to promote the heat conduction efficiency who gathers energy support 100.

Alternatively, each spoiler 21 may be block-shaped, plate-shaped, columnar-shaped, or other shapes. The plurality of spoiler members 21 in each spoiler assembly 20 may be disposed at intervals or continuously along the circumferential direction thereof. Alternatively, the spoiler 21 and the concentrator 10 may be integrally formed or separately formed.

Further, the number of the turbulence assemblies 20 is at least two, and all the turbulence assemblies 20 are arranged at intervals along the flowing direction of the fuel gas. Therefore, during the flowing process of the gas, the turbulence component 20 can sufficiently disturb the gas, so that the intensity of the formed turbulence is larger, and therefore, the gas can strongly impact the troposphere, so that the energy concentrating bracket 100 has higher heat conduction efficiency.

The energy concentrating bracket 100 further comprises an inner insulating layer (not shown) and/or an outer insulating layer (not shown), the energy concentrating element 10 has an inner surface 111 comprising a premixing surface 112 and a combustion surface 114, the inner insulating layer covers the inner surface 111, and the outer insulating layer covers an outer surface 131 of the energy concentrating element 10 facing away from the inner surface 111. Alternatively, the energy concentrating bracket 100 may include only the inner insulating layer, only the outer insulating layer, or both the inner insulating layer and the outer insulating layer. Through setting up interior heat preservation and/or outer heat preservation for gather and to have better thermal-insulated heat preservation effect by piece 10, consequently, the heat that the gas combustion produced can be less and spread to the outside slowly, thereby can further promote the heat conduction efficiency who gathers ability support 100.

The energy gathering member 10 is provided with an air inlet passage, and the air inlet passage is communicated between one of the premixing passage 123 and the combustion passage 125 and the outside. Therefore, when the burner 200 is in operation, the external secondary air may sequentially flow into the combustion channel 125 through the intake channel and the premixing channel 123, or directly flow into the combustion channel 125 through the intake channel and be sufficiently mixed with the gas, so that the gas can be sufficiently combusted. Thus, the content of the generated carbon monoxide is reduced, and the environment-friendly performance is better. Moreover, due to the arrangement of the intake passage, the combustion passage 125 and the premixing passage 123 can exchange heat with the outside through the intake passage, so that the temperature in the combustion passage 125 and the premixing passage 123 can be reduced, and the formation of nitrogen oxides due to the overhigh temperature in the combustion passage 125 and the premixing passage 123 can be prevented, thereby further reducing the environmental pollution. Furthermore, in the process of the secondary air flowing through the air inlet passage, the secondary air is in contact with the inner wall of the air inlet passage, and therefore, the secondary air can also absorb the heat of the energy gathering member 10 to have a higher temperature, so that when the secondary air flows into the energy gathering cavity 12, the heat generated by the combustion of the gas is not needed to be used for heating the secondary air, or only a very small part of the heat is needed to be used for heating the secondary air, and the heat generated by the combustion can be concentrated to be used for heating the cooking utensil 300, thereby having a higher heat conduction efficiency.

It is worth mentioning that the air inlet passage has a certain length in order to ensure that the secondary air can contact with the inner wall of the air inlet passage and exchange heat while flowing through the air inlet passage. The air in the gas is a gas mixed with the combustion gas before the gas is ejected from the burner 200, and the secondary air is a gas mixed with the gas outside the burner 200.

In addition, since the total amount of gas in the combustion path 125 is reduced during the combustion of the gas, a negative pressure lower than the external atmosphere is formed in the combustion path 125, so that the secondary air can be sucked into the combustion path 125 by the external atmospheric pressure. Further, since the gas is turbulently combusted in the combustion channel 125, the entrainment of the secondary air by the combustion channel 125 is enhanced, so as to accelerate the flow rate of the external secondary air into the combustion channel 125, thereby enabling the gas to be sufficiently combusted.

Alternatively, the intake passage may communicate with combustion passage 125 via premix passage 123, or may communicate directly with combustion passage 125. In one embodiment, the intake passage communicates between the outside and the combustion passage 125. Therefore, in the combustion process, the secondary air can directly enter the combustion channel 125 through the air inlet channel, the path through which the secondary air passes is shorter, and the supplementing speed is also faster, so that the secondary air can be fully mixed with the gas, and the gas can be fully combusted. Also, the secondary air flowing into the combustion channel 125 may also be disturbed by the spoiler assembly 20, so that the secondary air is more sufficiently mixed with the gas.

Referring to fig. 3 again, and referring to fig. 4, further, the energy concentrating element 10 is a double-layer structure and includes an inner sidewall 11 and an outer sidewall 13, the inner sidewall 11 has an inner surface 111 including a premixing surface 112 and a combustion surface 114, the outer sidewall 13 is coupled to a side of the inner sidewall 11 opposite to the inner surface 111, and forms a preheating chamber 126 with the inner sidewall 11; an air inlet (not shown) is arranged on the outer side wall 13, an air outlet 115 is arranged on the inner side wall 11, and the air inlet, the preheating cavity 126 and the air outlet 115 are sequentially communicated to form an air inlet channel. Compared with the method of directly forming the air inlet channel on the solid energy collecting piece 10, since the secondary air is output from the air inlet hole through the preheating cavity 126 and the air outlet hole 115, and the air inlet cavity has a larger space compared with the air inlet hole, when the secondary air flows into the preheating cavity 126, the secondary air is diffused and contacts with the cavity wall of the preheating cavity 126, so that the contact area of the secondary air and the cavity wall of the preheating cavity 126 is larger, and the contact time is relatively longer, therefore, the secondary air absorbs more heat, and the temperature of the secondary air flowing into the combustion channel 125 is higher, thereby the energy collecting support 100 has higher heat conduction efficiency. Specifically, it will be appreciated that the outer sidewall 13 is disposed on a side of the inner sidewall 11 facing away from the inner surface 111 thereof, and that the surface of the outer sidewall 13 facing away from the inner sidewall 11 forms the outer surface 131 described above.

Optionally, the number of the air inlet channel may be one, or may also be multiple, in an embodiment, a plurality of air inlets are formed in the outer side wall 13, one side of each spoiler 21 is provided with an air outlet, and the air outlets formed in one side of each spoiler 21 correspond to the air inlets one by one. The corresponding air inlet and outlet and the preheating chamber 126 together form an air inlet channel. Therefore, each spoiler 21 is provided with an air inlet channel corresponding to the spoiler, and in the combustion process, secondary air can enter the combustion cavity from the air inlet channels and can be fully mixed with fuel gas under the action of the spoilers 21.

Alternatively, the preheating chamber 126 may communicate with the outside only through the air inlet, or the preheating chamber 126 may also communicate with the outside through the other communication port 132. In one embodiment, the end of the energy gathering member 10 close to the panel is further opened with a communication port 132 communicating with the preheating chamber 126, the preheating chamber 126 communicates with the outside through the communication port 132, and the communication port 132 is different from the first mounting port 121. In this way, the path of the secondary air flowing into the energy collecting chamber 12 is increased, so that sufficient combustion of the gas is achieved.

In the gas stove 1 and the energy-gathering bracket 100 thereof, the aperture of the premixing channel 123 is gradually reduced along the flowing direction of the gas, and under the condition that the flow rate is not changed, when the gas passes through the premixing channel 123, the speed of the gas is gradually increased, so that the gas can flow into the combustion channel 125 at a high speed, further, because the turbulent flow component 20 is accommodated in the combustion channel 125 and protrudes out of the combustion surface 114, under the action of the turbulent flow component 20, the gas flowing at a high speed is stirred and switched to a turbulent flow state, and the gas in the turbulent flow state continuously impacts the convection layer adhered to the outer side wall 13 of the cooking appliance 300, so that the thickness of the convection layer is thinned, and thus the heat can be more quickly transferred to the cooking appliance 300. It can be seen that the gas burner 1 and the energy concentrating bracket 100 thereof in the present application have higher heat conduction efficiency.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
