Referring to fig. 1, 2 and 3 together, the present application provides a burner 100, wherein the burner 100 is used for heating a cooking utensil. The combustor 100 includes a combustion main body 10 and an ionization part 20, a plurality of combustion holes 11 capable of supplying gas combustion are provided on the combustion main body 10, the ionization part 20 is connected to the combustion main body 10, and includes a plurality of ionization parts 21, the plurality of ionization parts 21 correspond to the plurality of combustion holes 11 one by one, each ionization part 21 is arranged in the combustion hole 11 corresponding to it in a penetrating manner, and is arranged at an interval with the hole wall of the corresponding combustion hole 11, wherein a potential difference capable of ionizing gas and generating active groups (for example, O, H, CH3, O3 and NO) exists between each ionization part 21 and the hole wall of the corresponding combustion hole 11.

When the burner 100 is operated, gas flows into each of the combustion holes 11 and is combusted in each of the combustion holes 11, and heat generated by the combustion is transferred to the cooking appliance through the combustion body 10 and the convection of air, thereby heating the cooking appliance. Due to the existence of the potential difference, the fuel gas introduced into each fuel gas hole can be ionized under the action of the potential difference and generate active groups. The active groups can be mixed with the fuel gas and support combustion of the fuel gas, so that the fuel gas can be sufficiently combusted, and the thermal efficiency of the combustor 100 can be effectively improved. In addition, the active groups can react with harmful gases (e.g., carbon monoxide) formed after combustion of the fuel gas to generate harmless gases (e.g., carbon dioxide), so that the burner 100 has better environmental protection performance. Further, since the combustion and ionization of the gas are performed in the combustion holes 11, the high temperature generated during the combustion process can also promote the ionization and generate active radicals with higher concentration, so as to better promote the combustion of the gas and reduce the emission of harmful gases, and therefore, the burner 100 has higher thermal efficiency and better environmental protection performance.

Specifically, the gas in each combustion hole 11 may be ignited by an ignition pin additionally provided to the burner 100, or may be ignited by the ionization part 20 in cooperation with the combustion body 10. Preferably, the gas in each combustion hole 11 is ignited by the ionization part 20 in cooperation with the combustion body 10. In this way, the trouble of providing the ignition needle can be reduced, thereby making the structure of the burner 100 simpler and the manufacturing cost lower. Specifically, before the gas in each combustion hole 11 is not ignited, the potential difference between each ionization part 21 and the hole wall of its corresponding combustion hole 11 is controlled to be a voltage difference capable of igniting the gas, so that the gas in each combustion hole 11 can be ignited. Then, the potential difference between each ionization part 21 and the wall of the corresponding combustion hole 11 is controlled to be a potential difference capable of ionizing the gas and generating active radicals, so as to ionize the gas.

Referring to fig. 4, specifically, each ionization part 21 may be electrically connected to the high voltage positive electrode, and the combustion main body 10 may be electrically connected to the high voltage negative electrode, or each ionization part 21 may be electrically connected to the high voltage negative electrode, and the combustion main body 10 may be electrically connected to the high voltage positive electrode. Preferably, the combustion body 10 and the ionization element 20 are both conductive members (e.g., metal), each ionization part 21 is electrically connected to an external high-voltage positive electrode, and the combustion body 10 is grounded, so that a potential difference of the ionized gas can be formed between each ionization part 21 and the wall of the corresponding combustion hole 11. It will be appreciated that grounding of the combustion body 10 may be achieved by the combustion body 10 being carried directly on an external mounting surface (e.g. the ground, or a table top). Since the combustion body 10 is located outside the ionization element 20, the combustion body 10 is directly placed on the installation surface to be grounded, and the ionization part 21 is electrically connected to the high-voltage positive electrode to form a potential difference, so that the operation is simple and convenient.

More specifically, the combustion body 10 is provided with a plurality of connection holes (not shown), the plurality of connection holes correspond to the plurality of combustion holes 11 one by one, and each connection hole penetrates through the combustion body 10 along the radial direction of the combustion body 10 and is connected between the corresponding combustion hole 11 and the outside. The burner 100 further comprises a plurality of conductive members 7, wherein the plurality of conductive members 70 correspond to the plurality of connecting holes one by one, and each conductive member 70 is inserted into the corresponding connecting hole and connected between the ionization part 21 and the high-voltage positive electrode corresponding to the conductive member 70, so as to realize the electrical connection between the high-voltage electrode and the ionization part 21. In order to prevent each ionization part 21 from being electrically connected to the combustion body 10 to cause a short circuit, it is required to ensure that each ionization part 21 is not in contact with the combustion body 10, and an insulating material is coated on the surface of each conductive member 70 to separate the combustion body 10 from the conductive member 70.

It is defined that each ionization part 21 has a plurality of ionization position points, all the ionization position points on each ionization part 21 are combined to form the outer surface of the ionization part 21, and it is defined that each combustion hole 11 has a plurality of combustion position points on the hole wall, and all the combustion position points on the hole wall of each combustion hole 11 are combined to form the hole wall of the combustion hole 11. Each ionization part 21 is arranged in the corresponding combustion hole 11 in a penetrating manner, and a potential difference exists between the ionization part and the wall of the corresponding combustion hole 11, specifically, each ionization position point on each ionization part 21 has a combustion position point corresponding to the ionization part in the corresponding combustion hole 11, and a potential difference is formed between the corresponding combustion position point and the corresponding ionization position point. In this way, in each combustion hole 11, the gas may be ionized at any position, so that the gas has better ionization reliability, and further, the burner 100 has higher thermal efficiency and better environmental protection performance.

Referring to fig. 2 and 4 again, each ionization part 21 includes an ionization main body 212 and a plurality of ionization branch parts 214, the ionization main body is inserted into the corresponding combustion hole 11, all the ionization branch parts 214 are arranged on the ionization main body 212 at intervals, and a potential difference exists between the ionization main body 212 and each ionization branch part 214 and the hole wall of the corresponding combustion hole 11. Specifically, the ionization main body 212 and each ionization branch 214 have several combustion points thereon, and the combination of the combustion points on the ionization main body 212 and all ionization branch 214 forms the outer surface of the ionization part 21. Each ionization position point on the ionization main body part 212 and each ionization position point on each ionization branch part 214 have corresponding combustion position points on the hole wall of the corresponding combustion hole 11, and a potential difference is formed between the combustion position points and the ionization position points which are in one-to-one correspondence. By arranging the ionization main body part 212 and the ionization branch parts 214, the surface area of each ionization part 21 can be effectively increased, so that each ionization part 21 has more ionization position points, and correspondingly, the hole wall of each combustion hole 11 also has combustion position points corresponding to the ionization position points. In this way, the burner 100 has more corresponding ionization sites and potential differences between the combustion sites, thereby enabling the gas to be better ionized.

Alternatively, in each ionization section 21, the ionization main body section 212 extends in the axial direction of the combustion hole 11 corresponding thereto, and several ionization branch sections 214 may be provided at intervals in the extending direction of the ionization main body section 212, or may be provided around the circumferential direction of the ionization main body section 212, or the like.

Of course, in other embodiments, the shape of the ionization part 21 is not limited to the above one, and in another embodiment, each ionization part 21 may include only the ionization main body part 212. In other embodiments, there may be a portion of the ionization part 21 including the ionization main body part 212 and several ionization branch parts 214, and the remaining portion of the ionization part 21 including only the ionization main body part 212.

Further, a plurality of combustion holes 11 are arranged in groups to form a plurality of groups of combustion holes, the plurality of groups of combustion holes are arranged at intervals in the radial direction of the combustion body 10, and all the combustion holes 11 in each group of combustion holes are arranged at intervals in the circumferential direction of the combustion body 10. Correspondingly, a plurality of ionization parts 21 are arranged in groups to form a plurality of groups of ionization parts, the plurality of groups of ionization parts are arranged along the radial direction of the combustion main body 10 at intervals, and all the ionization parts 21 in each group of ionization parts are arranged along the circumferential direction of the combustion main body 10 at intervals. Therefore, when the gas in all the combustion holes 11 is combusted, the heat generated by the combustion of the gas can be uniformly diffused to the outside and uniformly heat the cooking appliance.

Furthermore, the ionization part 20 further includes a connection part 22, and any two ionization parts 21 are connected with each other through the connection part 22. This provides the ionization element 20 with a better integrity to facilitate assembly of the ionization element 20. Specifically, the connection portion 22 is also made of a metal material, and the connection portion 22 and the ionization portions 21 may be integrally formed.

Referring to fig. 3 again, specifically, the combustion body 10 includes a main housing 12 and a combustion body 14, the main housing 12 has a receiving cavity 121, the main housing 12 is provided with an air inlet 123 and an air outlet 125, the combustion body 14 is provided with a plurality of combustion holes 11, and the air inlet 123, the receiving cavity 121, each combustion hole 11 and the air outlet 125 are sequentially communicated. Specifically, the main housing 12 and the combustion body 14 are both conductive members, the main housing 12 has a supporting and protecting function for the combustion body 14, and the main housing 12 can prolong the service life of the combustion body 14, so that the service life of the burner 100 can be further prolonged. Specifically, during the operation of the burner 100, the gas flows in from the gas inlet 123, passes through the accommodating cavity 121, flows into each combustion hole 11, and is combusted, and the harmless gas generated by the combustion is discharged to the outside from the gas outlet 125, while part of the heat generated by the combustion is transmitted to the cooking appliance through the combustion body 14 and the main housing 12 in sequence, and the rest of the heat can be transmitted to the cooking appliance through the gas outlet 125 by the air pair.

Specifically, each combustion hole 11 may penetrate the combustion body 10 in the axial direction of the combustion body 10 and directly communicate with the air outlet 125; alternatively, the combustion body 14 may be a porous member, and a plurality of communication holes (not shown) may be formed in the combustion body 14, each combustion hole 11 is communicated with the gas outlet 125 through at least one communication hole, and different combustion holes 11 are communicated with the gas outlet 125 through at least one different communication hole. In addition, the combustion hole 11 and the ionization part 21 corresponding to the combustion hole are approximately matched in shape, so that the distance between the hole wall of the combustion hole 11 and the corresponding ionization part 21 can be smaller, and the distance between the hole wall of the combustion hole 11 and the corresponding ionization part 21 meets the ionization requirement.

Further, the burner 100 further includes a back fire prevention member 30, the back fire prevention member 30 is coupled in the receiving cavity 121 and located on a side of the combustion body 14 facing the air inlet 123, and a plurality of back fire prevention holes are opened on the back fire prevention member 30, and each of the back fire prevention holes is configured to allow gas to pass through. Specifically, each of the flashback-preventing holes penetrates the flashback-preventing member 30 in the axial direction of the combustion body 10. When the burner 100 is operated, the gas flows into the receiving cavity 121 from the gas inlet 123 and flows into the combustion hole 11 through the anti-backfire hole. In the process of burning the gas in each combustion hole 11, the flame generated by the burning of the gas may overflow in the direction toward the gas inlet 123 to form a back fire, and the gas concentration at the inlet and outlet is generally higher than that in each combustion hole 11, so that the gas is easily detonated due to the back fire, which causes a serious safety accident. By arranging the anti-backfire member 30, the anti-backfire member 30 is provided with a plurality of dense anti-backfire holes, and when backfire enters at least part of the anti-backfire holes, the burner 100 is easily extinguished due to oxygen deficiency, so that the burner 100 has higher safety.

Alternatively, the flashback arrestor 30 can be spaced apart from the combustion body 14 or can be positioned in close proximity to the combustion body 14. Preferably, the side of the anti-backfire element 30 facing the burner body 14 abuts the burner body 14. Therefore, heat generated by combustion of the gas in each combustion hole 11 can be transferred to the backfire preventing member 30 through the combustion body 14, and the gas can be preheated by the backfire preventing member 30 during the process that the gas passes through the gas inlet 123 and the receiving cavity 121 and flows through each backfire preventing hole, thereby enabling the burner 100 to have higher thermal efficiency.

Referring to fig. 2 again, in the further embodiment, the anti-backfire element 30 is recessed toward the surface of the combustion body 14 to form a clearance groove 32, and when the combustion body 14 is attached to the anti-backfire element 30, the connecting portion 22 is received in the clearance groove 32 for clearance. In this way, the tightness of the installation of the combustion body 14 and the flashback-preventing member 30 can be further improved. It should be noted that, in order to prevent the connecting portion 22 from short circuit caused by the contact between the connecting portion 22 and the main housing 12 through the release and tempering member, when the connecting portion 22 is received in the avoiding groove 32, the connecting portion 22 should be spaced from the groove wall of the avoiding groove 32.

The burner 100 further comprises an injection pipe 40 and a nozzle 50, the injection pipe 40 is connected to the air inlet 123 and communicated with the air inlet 123, the nozzle 50 and one end of the injection pipe 40 far away from the air inlet 123 are arranged at intervals, and the nozzle 50 is used for injecting fuel gas into the injection pipe 40, so that the fuel gas can enter the accommodating cavity 121 through the injection pipe 40 and the air inlet 123. And because the nozzle 50 with draw and penetrate the pipe 40 and keep away from the one end of air inlet 123 and be the interval setting, consequently, at the in-process that the nozzle 50 jetted the gas to drawing the pipe 40, because the gas has higher speed, the gas can drive around draw the pipe 40 and keep away from the one end of air inlet 123 and the air around the nozzle 50 and flow into to drawing in the pipe 40 to make the air can with the gas carry out intensive mixing in drawing the pipe 40, thereby can further promote the sufficiency of burning, make the combustor 100 have higher thermal efficiency.

The combustor 100 also includes a gathering ring 60, the gathering ring 60 coupled to the air outlet 125 and in communication with the air outlet 125. When the burner 100 is operated, the cooking utensil is coupled to the end of the energy concentrating ring 60 away from the air outlet 125, and heat generated by combustion of gas can be transferred from the combustion body 14 to the cooking utensil through the energy concentrating ring 60, can also be transferred to the cooking utensil through the combustion body 14 and the main housing 12, and can also be transferred to the cooking utensil by air convection. The energy gathering ring 60 has an effect of gathering energy, and by providing the energy gathering ring 60, it is possible to prevent heat from being rapidly diffused to the outside, so that the heat can be intensively applied to the cooking appliance, thereby facilitating further improvement of the heat efficiency of the burner 100.

In the burner 100, each ionization part 21 is inserted into the corresponding combustion hole 11, and a potential difference exists between each ionization part 21 and the corresponding hole wall of the combustion hole 11, which can ionize the gas and generate active radicals, so that when the gas flows into each combustion hole 11 and is combusted in the combustion hole 11, the gas can be ionized and form active radicals, and the active radicals can be mixed with the gas and enable the gas to be fully combusted, thereby improving the thermal efficiency of the burner 100. In addition, the active groups can react with harmful gases (such as carbon monoxide) generated after combustion of the fuel gas and generate harmless gases (such as carbon dioxide), so that the burner 100 has better environmental protection performance. Moreover, since the combustion and ionization of the fuel gas are performed in the combustion holes 11, the high temperature generated during the combustion process can also promote the ionization and generate active radicals with higher concentration, so as to further promote the combustion and reduce the emission of harmful gases, and thus the burner 100 has higher thermal efficiency and better environmental performance.

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 express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
