Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0036] In the present invention, the first direction described is the direction of A-A shown in the drawings, the second direction is the direction of B-B shown in the drawings, and the third direction is the direction of C-C shown in the drawings.

[0037] Combined with Figure 1 and Figure 2 , according to the air-blowing assembly 100 of the embodiment of the present invention, it can be used for the burner 1000. The air-blowing assembly 100 includes a housing 10 and a fan 20. The housing 10 defines an air-blowing chamber 11, and the air-blowing chamber 11 has a first air inlet 111 and an air outlet 112. The fan 20 is communicated with the first air inlet 111 and is used for blowing primary air into the air-blowing chamber 11. Specifically, the fan 20 conveys primary air into the air-blowing chamber 11 through the first air inlet 111, and the primary air is discharged from the air outlet 112. It should be noted that the primary air refers to the air that is pre-mixed with the fuel. When the fuel burns, sufficient air is required. By providing the air-blowing assembly 100, air is forcibly supplemented for the burner to promote the full combustion of the fuel.

[0038] The blower assembly 100 may further include a nozzle 30. The nozzle 30 is connected to the outside of the housing 10 and is disposed opposite to the air outlet 112 in the first direction. In other words, the air outlet 112 is provided upstream of the nozzle 30. The blower chamber 11 supplies primary air to the nozzle 30 along the first direction through the air outlet 112, which helps the gas output by the nozzle 30 to be mixed with the air, provides sufficient air for the burner 1000, and reduces the emission of pollutants caused by incomplete combustion of the gas. The first air inlet 111 is provided at one end of the housing 10 in the second direction. The first direction and the second direction are arranged at an angle. In other words, the inlet direction of the primary air is different from the outlet direction. After the air enters the blower chamber 11, the air flow experiences dynamic pressure attenuation in the inlet direction and part of it is converted into static pressure, so that the air can flow out evenly from the air outlet 112, which helps the full mixing of the air and the gas.

[0039] Wherein, the first direction and the second direction are arranged at an angle. Exemplarily, the angle can be a right angle, an acute angle or an obtuse angle, etc. It can be understood that if the fan 20 is directly facing the air outlet 112, the air flow path is single after the air enters the blower chamber 11. The air flow velocity is large at the position where the air outlet 112 is directly opposite to the air inlet 112, while the air flow at other positions of the air outlet 112 will be relatively small. The uneven air flow velocity flowing out from the air outlet 112 will cause uneven mixing of the air and the gas. By setting a certain angle between the air inlet direction and the air outlet direction, after the air flow enters the blower chamber 11, it experiences dynamic pressure attenuation in the air inlet direction, and the dynamic pressure is converted into static pressure, so that the air flow can flow out evenly from the air outlet 112, thereby improving the mixing uniformity of the primary air and the gas.

[0040] According to the blower assembly 100 of the burner in the embodiment of the present invention, the fan 20 conveys primary air into the blower chamber 11 through the air inlet, and there is an angle between the air inlet direction and the air outlet direction of the blower assembly 100. The air flow experiences dynamic pressure attenuation in the air inlet direction, and the dynamic pressure is converted into static pressure, making the air flow flowing out from the air outlet 112 more uniform, improving the mixing uniformity of the air and the gas, and further promoting the full combustion of the gas and reducing the emission of pollutants.

[0041] The burner 1000 in the embodiment of the present invention can be used in gas stoves, etc. An ejection channel 210 may be provided in the burner 1000. The fan 20 blows air into the blower chamber 11. The air flow flows out from the air outlet 112 and is mixed with the gas ejected from the nozzle 30 and then enters the ejection channel 210. By providing the blower assembly 100 to force-feed air for the burner 1000, sufficient air is provided for the burner 1000, and the air outlet of the blower assembly 100 is uniform, which can improve the combustion efficiency of the burner 1000, reduce the emission of pollutants caused by incomplete combustion, and further improve the energy efficiency of the gas equipment.

[0042] Combined with Figure 1, in some embodiments of the present utility model, the first direction is perpendicularly arranged with respect to the second direction. Specifically, the air inlet direction of the primary air is perpendicular to the air outlet direction. After the air enters the air blowing chamber 11, the dynamic pressure of the air flow rapidly decays in the air inlet direction, and most of the dynamic pressure is converted into static pressure, so that the air flow can uniformly flow out from the air outlet 112 along the second direction, improving the mixing uniformity of the primary air and the fuel gas.

[0043] Exemplarily, the air inlet direction of the air blowing chamber 11 can be perpendicular to the extending direction of the injection channel 210. That is to say, the air inlet direction is perpendicular to the air inlet direction of the burner 1000. After the air enters the air blowing chamber 11, the dynamic pressure of the air flow decays in the direction perpendicular to the air inlet direction, and the dynamic pressure is converted into static pressure, so that the air flow can flow out from the air outlet 112 more uniformly, and then the air flow can be uniformly mixed with the fuel gas, promoting the full combustion of the fuel gas.

[0044] Combined with Figure 1 and Figure 2 , in some embodiments of the present utility model, the nozzle 30 extends along the first direction, and the first air inlet 111 extends along the second direction. Specifically, the fan 20 conveys the primary air to the air blowing chamber 11 along the second direction, and the air flow flows out from the air outlet 112 along the first direction. The nozzle 30 conveys the fuel gas to the burner main body 200 along the first direction, and the direction of the fuel gas ejected by the nozzle 30 is the same as the air outlet direction of the air blowing chamber 11, so as to facilitate the full mixing of the primary air and the fuel gas and improve the mixing uniformity of the air and the fuel gas.

[0045] Combined with Figure 2 , in some embodiments of the present utility model, the rotation axis of the impeller 21 of the fan 20 extends along the third direction, and the third direction is perpendicularly arranged with respect to the first direction and the second direction respectively, which can facilitate the diffusion of the air flow blown by the fan 20 in the air blowing chamber 11, and the air flow blown out from the air outlet 112 is uniform. Exemplarily, the first direction can be the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0046] In some embodiments of the present utility model, the air outlet 112 is at least one and the air outlet 112 extends along the circumferential direction of the nozzle 30. Specifically, the air outlet 112 can be one, or the air outlet 112 can be multiple. Exemplarily, the air blowing assembly 100 can include one nozzle 30, the air outlet 112 is one and the air outlet 112 extends along the circumferential direction of the nozzle 30; the air blowing assembly 100 can include two nozzles 30, the air outlet 112 can be one, and the air outlet 112 can extend along the circumferential direction of one of the nozzles 30, or one air outlet 112 is arranged around the two nozzles 30, that is to say, one air outlet 112 provides air to the two nozzles 30 at the same time; the air blowing assembly 100 can include two nozzles 30, and the air outlet 112 can also be two, and each nozzle 30 is correspondingly provided with one air outlet 112. By extending the air outlet 112 along the circumferential direction of the nozzle 30, it is convenient for the airflow of the air outlet 112 to form a surround around the gas ejected from the nozzle 30, which helps the mixing of the gas and the air.

[0047] Wherein, the air outlet 112 extends along the circumferential direction of the nozzle 30, and the air outlet 112 can be configured as an arc, a circular ring, a square ring, etc.

[0048] Combined with Figure 3 , in some embodiments of the present utility model, the air outlet 112 includes a plurality of air outlet holes 1121 and the plurality of air outlet holes 1121 are arranged in the circumferential direction of the nozzle 30. Specifically, the air outlet 112 can be provided with a plurality of air outlet holes 1121 and the plurality of air outlet holes 1121 are arranged at intervals along the circumferential direction of the nozzle 30, surrounding the outer periphery of the nozzle 30, capable of forming a wrap around the nozzle 30. The airflow flowing out of the air outlet holes 1121 and the gas ejected from the nozzle 30 enter the ejector passage 210 of the burner 1000 together, improving the mixing uniformity of the gas and the air, promoting sufficient combustion, reducing pollutant emissions, and improving the energy efficiency level of the gas equipment.

[0049] Combined with Figure 4 and Figure 5, in some embodiments of the present utility model, an air intake passage 12 is further defined within the housing 10. The air intake passage 12 is separated from the blower chamber 11. The inlet 121 of the air intake passage 12 is adapted to communicate with the outside, and the outlet 122 of the air intake passage 12 is connected to the nozzle 30. Exemplarily, the inlet 121 of the air intake passage 12 can be connected to a gas tank, a natural gas pipeline, a fuel valve, etc. The gas flows through the air intake passage 12 towards the nozzle 30 and is sprayed through the nozzle 30 towards the ejector tube of the burner 1000. Among them, the air intake passage 12 is defined within the housing 10. Exemplarily, the burner 1000 can include an air pipe that passes through the housing 10 to define the air intake passage 12 within the housing 10; it can also be that there is an air pipe within the housing 10. In other words, the air pipe is a part of the housing 10. By defining the air intake passage 12 within the housing 10 and separating the air intake passage 12 from the blower chamber 11, the structure of the burner 1000 is made compact, and the space utilization rate of the burner 1000 is improved.

[0050] Furthermore, in combination with Figure 6 , the housing 10 can include an outer shell 13 and an air inlet pipe 14. The first air inlet 111 and the air outlet 112 are provided on the outer shell 13; the air inlet pipe 14 extends along a first direction and passes through the outer shell 13. The air inlet pipe 14 defines the air intake passage 12, and one end of the air inlet pipe 14 is connected to the nozzle 30. The outer wall of the air inlet pipe 14 and the inner wall of the outer shell 13 define the blower chamber 11. Both ends of the air inlet pipe 14 can extend out of the outer shell 13 to facilitate the connection of one end of the air inlet pipe 14 to an external pipeline and the other end to the nozzle 30, improving the assembly efficiency of the blower assembly 100. Moreover, the air inlet pipe 14 extends along the first direction, and the extension direction of the air inlet pipe 14 is the same as the air outlet direction of the blower chamber 11, facilitating the uniform mixing of the primary air and the gas sprayed from the nozzle 30. The structure of the blower assembly 100 is compact, and it is convenient for the mixing of the gas and the primary air.

[0051] Among them, the outer shell 13 and the air inlet pipe 14 can be integrally formed, which can improve the structural strength of the housing 10. Of course, the air inlet pipe 14 can be assembled to the outer shell 13 to facilitate the processing and forming of the housing 10.

[0052] In addition, the air inlet pipe 14 can include a first air inlet pipe and a second air inlet pipe, and the nozzle 30 can include a first nozzle 31 and a second nozzle 32. Among them, one end of the first air inlet pipe is connected to the first nozzle 31, and one end of the second air inlet pipe 14 is connected to the second nozzle 32. Exemplarily, an inner ring air intake passage 12 can be defined within the first air inlet pipe 14, and an outer ring air intake passage 12 can be defined within the second air inlet pipe 14. The first air inlet pipe 14 and the second air inlet pipe 14 are arranged at intervals along a second direction.

[0053] In combination with Figure 4 and 6, in some embodiments of the present utility model, the housing 13 includes a cover shell 131 and a sealing plate 132. One side of the cover shell 131 has an opening, and the sealing plate 132 is used to open and close the opening. After the sealing plate 132 covers the opening, a closed air blowing cavity 11 is formed inside the housing 13. Among them, the sealing plate 132 is provided with an avoidance hole 1321 for avoiding the other end of the intake pipe 14, and the air outlet 112 is arranged on the wall body of the cover shell 131 opposite to the sealing plate 132. In other words, the other end of the intake pipe 14 extends out of the housing 13 to facilitate the connection of the other end of the intake pipe 14 to external intake pipe structures, valves, etc. By providing the cover shell 131 and the sealing plate 132, it is convenient for the processing and forming of the air blowing assembly 100 and improves the assembly efficiency of the air blowing assembly 100.

[0054] Combined with Figure 7 , in some embodiments of the present utility model, the number of nozzles 30 is at least two and includes a first nozzle 31 and a second nozzle 32, the number of air outlets 112 is at least two and includes a first air outlet 1122 and a second air outlet 1123. The first air outlet 1122 and the first nozzle 31 are arranged opposite to each other, and the second air outlet 1123 and the second nozzle 32 are arranged opposite to each other. Exemplarily, the first nozzle 31 can be an inner ring nozzle for supplying gas to the inner fire holes of the burner 1000, and the second nozzle 32 can be an outer ring nozzle for supplying gas to the outer fire holes of the burner 1000. The first air outlet 1122 and the inner ring nozzle are arranged opposite to each other, and the second air outlet 1123 and the outer ring nozzle are arranged opposite to each other. The primary air output from the first air outlet 1122 is mixed with the gas ejected from the inner ring nozzle, and the primary air output from the second air outlet 1123 is mixed with the gas ejected from the outer ring nozzle. The gas mixed with air enters the injection channel 210 of the burner 1000.

[0055] Among them, a wind blocking member 15 is connected to the outside of the housing 10. The wind blocking member 15 is located between the first air outlet 1122 and the second air outlet 1123 to separate the first air outlet 1122 and the second air outlet 1123. By providing the wind blocking member 15, the mutual interference between the first air outlet 1122 and the second air outlet 1123 can be reduced, and the combustion stability can be improved.

[0056] Exemplarily, the first nozzle 31 can be an inner ring nozzle. The first nozzle 31 is configured to spray gas into the inner ring injection pipe of the burner 1000, so as to supply gas to the inner fire holes of the burner 1000. The second nozzle 32 can be an outer ring nozzle. The second nozzle 32 is configured to spray gas into the outer ring injection pipe of the burner 1000 to supply gas to the outer fire holes of the burner 1000. Among them, combined with Figure 7 , the second nozzle 32 is closer to the first air inlet 111 than the first nozzle 31. By providing the wind blocking member 15 between the first air outlet 1122 and the second air outlet 1123, the mutual interference of the primary air supply for the inner and outer rings can be reduced, especially the interference of the outer ring on the inner ring.

[0057] Combined with Figure 7 and Figure 9 Furthermore, the wind shield 15 includes: a first wind shield 151 and a second wind shield 152. The first wind shield 151 is arranged around the first air outlet 1122 and its two ends extend in the direction away from the first air outlet 1122; the second wind shield 152 is arranged around the second air outlet 1123 and its two ends extend in the direction away from the second air outlet 1123. Wherein, a second air inlet 153 is defined between the two ends of the first wind shield 151 and between the two ends of the second wind shield 152. Specifically, the second air inlet 153 is defined between the two ends of the first wind shield 151, and the second air inlet 153 is defined between the two ends of the second wind shield 152. The second air inlet 153 can communicate with the outside, so as to pass a stream of air (natural wind) through the second air inlet 153.

[0058] Thus, by providing the air blowing assembly 100, the air blowing assembly 100 is provided with a first air inlet 111 to provide primary air blowing for the burner 1000, and a second air inlet 153 is defined between the two ends of the wind shield to provide primary air natural wind for the burner 1000, so as to facilitate the natural injection of the burner 1000. The first wind shield 151 and the second wind shield 152 cooperate. On the one hand, it can reduce the mutual interference of the airflows at the first air outlet 1122 and the second air outlet 1123, so as to stably supplement air to the gas ejected from the first nozzle 31 and the gas ejected from the second nozzle 32. On the other hand, the second air inlet 153 is defined to facilitate passing natural wind to the burner 1000 to achieve natural injection.

[0059] Optionally, the air volume of the fan 20 can be adjusted and can be adjusted according to actual usage requirements. For example, when high firepower is required, the air volume of the fan 20 can be increased to improve the combustion efficiency. When in low fire, the air volume of the fan 20 can be reduced or natural injection can be used to reduce the energy consumption of the gas equipment.

[0060] Of course, the start and stop of the fan 20 can also be controlled according to actual usage requirements. For example, when high firepower is required, the fan 20 can be turned on to increase the air volume of the primary air and improve the combustion efficiency. When in low fire, the fan 20 can be turned off and the primary air can be supplemented only by natural injection to reduce the energy consumption of the gas equipment.

[0061] Exemplarily, the first wind deflector 151 and the second wind deflector 152 may be semi-circular. The first wind deflector 151 is disposed around the first air outlet 1122, and the first air outlet 1122 is configured to supplement primary air through the inner ring nozzle. The second wind deflector 152 is disposed around the second air outlet 1123, and the second air outlet 1123 is configured to supplement primary air through the outer ring nozzle. By providing the first wind deflector 151 and the second wind deflector 152, on the one hand, a second air inlet 153 can be formed in communication with the outside to achieve natural draft of the burner 1000. On the other hand, the mutual interference of air supplementation between the inner and outer rings can be improved, so that the combustion of both the inner and outer rings can be carried out in their respective optimal states, which helps to improve the energy efficiency of the burner 1000.

[0062] Combined with Figures 8 to 10 , the burner 1000 according to an embodiment of the present invention includes: a burner main body 200 and the aforementioned air blowing assembly 100. The burner main body 200 has an induction channel 210 in communication with the outside. Among them, the induction channel 210 is in communication with the outside, facilitating the burner 1000 to naturally draft primary air.

[0063] By providing the aforementioned air blowing assembly 100, primary air is blown for the burner 1000. By combining the primary air blowing and the natural draft of primary air, the combustion efficiency of the burner 1000 is improved. The air blowing assembly 100 is connected to the burner main body 200 and at least part of the nozzle 30 is disposed in the induction channel 210. Exemplarily, the entire nozzle 30 can be disposed in the induction channel 210, or part of the nozzle 30 is disposed in the induction channel 210. By providing the aforementioned air blowing assembly 100, forced air supplementation is carried out for the burner 1000. The air outlet 112 of the air blowing assembly 100 has uniform air output, facilitating the uniform mixing of air and the gas ejected from the nozzle 30. The mixed gas enters the induction channel 210, enhancing the sufficiency of gas combustion and reducing pollutant emissions.

[0064] Combined with Figure 8 and Figure 9 , exemplarily, the air blowing assembly 100 can be located at the front end of the induction channel 210 and at the rear end of the gas equipment valve body and the internal gas pipeline. The fan 20 can be located in the vertical direction of the air inlet of the burner 1000. After the air enters the air blowing cavity 11, the dynamic pressure of the air flow rapidly decays in the direction perpendicular to the air inlet, and most of the dynamic pressure is converted into static pressure. The air can flow out more uniformly from the air outlet holes 1121, so that the air flow velocity is uniform, better mixing with the gas, promoting sufficient gas combustion, and reducing pollutant emissions.
