Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a gas supply component and a gas stove. Background Art

[0002] Current gas stoves usually mix air and gas, then spray the mixed gas of air and gas through a nozzle, and ignite the mixed gas to achieve combustion.

[0003] However, the market requirements for gas stove energy efficiency standards are gradually increasing. Currently, the thermal efficiency of gas stoves is relatively low and cannot meet the new energy efficiency standards. Summary of the Invention

[0004] Based on this, it is necessary to provide a gas supply assembly and a gas stove to address the problem that the thermal efficiency of current gas stoves is low and cannot meet the requirements of new energy efficiency standards.

[0005] In a first aspect, the present application provides an air supply assembly, comprising a nozzle assembly, a connecting member, and an air supply member, wherein the connecting member has an inner cavity and a first connecting port, a second connecting port, and a third connecting port respectively connected to the inner cavity, the first connecting port being connected to the nozzle assembly, and the second connecting port being used to introduce a combustion medium into the nozzle assembly; the air supply member having an air outlet connected to the third connecting port, the air supply member being used to deliver air into the inner cavity and mix the air with the combustion medium within the connecting member;

[0006] Wherein, the opening direction of the second communication port intersects with the opening direction of the third communication port.

[0007] With the above structure, the air supply member provides air to the inner cavity through the third communication port. Simultaneously, a combustion medium, such as gas, is introduced into the interior of the communication member through the second communication port, allowing the air and gas to mix within the communication member. Because the opening direction of the second communication port intersects with the opening direction of the third communication port, the air and gas are more evenly mixed. The evenly mixed gas is then fed into the nozzle assembly through the first communication port, where it is then combusted, effectively improving thermal efficiency.

[0008] In some embodiments, the nozzle assembly includes a first nozzle and a second nozzle that are independent of each other, and the connecting member includes a main body, a first branch pipe, and a second branch pipe. The inner cavity is formed inside the main body, one end of the first branch pipe is connected to the inner cavity, and the other end is configured as the first connecting port connected to the first nozzle; one end of the second branch pipe is connected to the inner cavity, and the other end is configured as the first connecting port connected to the second nozzle;

[0009] The third communication port is formed on the main body, and the second communication ports are formed on the first branch pipe and the second branch pipe respectively.

[0010] Therefore, through the above structure, independent ignition of the first nozzle and the second nozzle can be achieved, and the combustion heating range can be made larger and more uniform during the application process.

[0011] In some embodiments, the air supply assembly further includes a flow divider, which is disposed inside the first branch pipe and / or the second branch pipe and is located between the corresponding second communication port and the nozzle group along the flow direction of the air and the combustion medium;

[0012] The diverter is used to disperse the mixed air and the combustion medium.

[0013] Therefore, by providing the diverter, the air and the combustion medium can be dispersed at the position of the diverter and then mixed for the second time, so that the air and the combustion medium are mixed more fully and more evenly, further improving the thermal efficiency.

[0014] In some embodiments, the diverter includes a diverter plate fixed inside the first branch pipe and / or the second branch pipe, and a plurality of through holes are opened through the diverter plate along the flow direction of the air and the combustion medium, and the through holes are spaced apart from each other.

[0015] Therefore, by providing the diverter plate, the air and the combustion medium after the first mixing can be dispersed, so that the air and the combustion medium can be mixed for the second time, making the mixing of the air and the combustion medium more sufficient and more uniform.

[0016] In some embodiments, all of the through holes include a main hole and a plurality of auxiliary holes, the main hole is coaxially arranged with the diverter plate, and the auxiliary holes are arranged around the outer periphery of the main hole;

[0017] The flow diverter also includes a flow guide shaft coaxial with the main hole, the flow guide shaft having a first end and a second end oppositely arranged along its own axial direction, and the first end passes through the main hole;

[0018] Wherein, the diameter of the guide shaft gradually increases from the first end to the second end.

[0019] Therefore, through the cooperation of the diverter plate and the guide shaft, the air and the combustion medium can be mixed for the second time, so that the mixing of the air and the combustion medium is more sufficient and more uniform.

[0020] In some embodiments, the diameters of the secondary holes are different, so that when the mixed gas of air and gas passes through the secondary holes, a certain velocity difference can be formed, which is more conducive to uniform and sufficient mixing of the air and gas.

[0021] In some embodiments, the diameter of each secondary hole gradually decreases in a clockwise or counterclockwise direction. In this way, after the air and the combustion medium are dispersed through each secondary hole, they can be further mixed in the clockwise or counterclockwise direction, so that the mixing between the air and the combustion medium is more complete and uniform.

[0022] In some embodiments, the diverter further includes a fan blade, which is rotatably connected to the second end of the guide shaft, and the fan blade is configured to rotate around the guide shaft driven by the air passing through the diverter piece and the combustion medium.

[0023] In this way, after the air and the combustion medium are dispersed through the auxiliary holes, the airflow with a certain speed difference formed can drive the fan blades to rotate. On the one hand, under the rotation of the fan blades, the mixing effect between the air and the combustion medium can be further improved; on the other hand, since the airflow drives the fan blades to rotate, the speed of the overall airflow is reduced, which can make the combustion more stable.

[0024] In some embodiments, the second nozzle is disposed around the outer periphery of the first nozzle. Through the above structure, an inner ring fire and an outer ring fire are formed, which can expand the combustion coverage area.

[0025] In a second aspect, the present application also provides a gas stove comprising the gas supply assembly as described above.

[0026] In the above-mentioned air supply assembly and gas stove, the air supply member provides air to the inner cavity through the third connecting port, and at the same time, a combustion medium, such as gas, is introduced into the interior of the connecting member through the second connecting port, so that the air and gas can be mixed inside the connecting member; since the opening direction of the second connecting port is arranged to intersect with the opening direction of the third connecting port, the air and gas can be mixed more evenly, and the gas after even mixing is sent to the nozzle group through the first connecting port, and then combustion can be realized in the nozzle group, thereby effectively improving thermal efficiency.

[0041] Please also refer to Figure 1 、 Figure 2 as well as Figure 3An embodiment of the present application provides an air supply assembly 100, comprising a nozzle assembly 10, a connecting member 20, and an air supply member 30. The connecting member 20 has an inner cavity 21 and a first connecting port 22, a second connecting port 23, and a third connecting port 24, respectively connected to the inner cavity 21. The first connecting port 22 is connected to the nozzle assembly 10, and the second connecting port 23 is used to introduce a combustion medium into the nozzle assembly 10. The air supply member 30 has an air outlet 31 connected to the third connecting port 24. The air supply member 30 is used to deliver air into the inner cavity 21 and mix the air with the combustion medium inside the connecting member 20. The opening direction of the second connecting port 23 is arranged to intersect with the opening direction of the third connecting port 24.

[0042] It should be noted that the nozzle assembly 10 is a structure capable of receiving air and a combustion medium and outputting the mixed air and combustion medium for ignition. The connecting member 20 defines an inner cavity 21 and is provided with a first communication port 22, a second communication port 23, and a third communication port 24. The first communication port 22, the second communication port 23, and the third communication port 24 are connected to the inner cavity 21. In other words, air or the combustion medium can enter the inner cavity 21 through the first communication port 22, the second communication port 23, and the third communication port 24, and can also be output from the inner cavity 21 through the first communication port 22, the second communication port 23, and the third communication port 24.

[0043] Specifically, the first communication port 22 is connected to the nozzle assembly 10, and the second communication port 23 can be connected to an external gas supply device, and the combustion medium is introduced into the second communication port 23 through the external gas supply device. The combustion medium can be, but is not limited to, gas.

[0044] Furthermore, the second communication port 23 introduces the gas into the interior of the communication member 20 , so that the gas can be delivered to the nozzle assembly 10 via the first communication port 22 .

[0045] The air supply member 30 is a structure that can inhale air from the external environment and blow the air from the air outlet 31 to the third communication port 24 and the inner cavity 21. The air supply member 30 can be, but is not limited to, a centrifugal fan.

[0046] Air is drawn in from the outside environment by a centrifugal fan, blown from the air outlet 31 to the third communication port 24, and then enters the inner cavity 21 through the third communication port 24. After entering the inner cavity 21, the air continues to flow toward the nozzle assembly 10 under the action of the centrifugal fan. When the air passes through the location of the second communication port 23, it mixes with the fuel gas introduced by the second communication port 23. The mixed gas is then delivered to the nozzle assembly 10, where it can be ejected and ignited.

[0047] Furthermore, the opening direction of the second communication port 23 intersects the opening direction of the third communication port 24. In a specific embodiment, the opening directions of the second communication port 23 and the third communication port 24 can be perpendicular to each other. That is, the flow direction of the gas entering the communication member 20 and the flow direction of the air entering the communication member 20 are perpendicular to each other. This allows for more complete and uniform mixing of the air and gas, resulting in more complete combustion of the mixed gas in the nozzle assembly 10, thereby improving thermal efficiency.

[0048] With the above structure, the air supply member 30 provides air to the inner cavity 21 through the third communication port 24. At the same time, a combustion medium, such as gas, is introduced into the interior of the communication member 20 through the second communication port 23, allowing the air and gas to mix within the communication member 20. Because the opening direction of the second communication port 23 intersects the opening direction of the third communication port 24, the air and gas can be mixed more evenly. The evenly mixed gas is then introduced into the nozzle assembly 10 through the first communication port 22 and then combusted in the nozzle assembly 10, thereby effectively improving thermal efficiency.

[0049] like Figure 4 and Figure 5 As shown, in some embodiments, the nozzle assembly 10 includes a first nozzle 11 and a second nozzle 12 that are independent of each other, and the connecting member 20 includes a main body 25, a first branch pipe 26, and a second branch pipe 27. An inner cavity 21 is formed inside the main body 25. One end of the first branch pipe 26 is connected to the inner cavity 21, and the other end is configured as a first connecting port 22 that is connected to the first nozzle 11. One end of the second branch pipe 27 is connected to the inner cavity 21, and the other end is configured as the first connecting port 22 that is connected to the second nozzle 12. The third connecting port 24 is defined on the main body 25, and the first branch pipe 26 and the second branch pipe 27 each define a second connecting port 23.

[0050] Specifically, the first nozzle 11 and the second nozzle 12 are independent of each other, meaning that ignition can be achieved independently at the first nozzle 11 and the second nozzle 12. The connecting member 20 includes a body 25, a first branch pipe 26, and a second branch pipe 27. The first branch pipe 26 and the second branch pipe 27 are respectively connected to the body 25. The interior of the body 25 is hollow to form an inner cavity 21.

[0051] One end of the first branch pipe 26 communicates with the inner cavity 21, and the other end forms a first communication port 22, which communicates with the first nozzle 11. A second communication port 23 is defined in the first branch pipe 26. This allows the air supply member 30 to first deliver air into the inner cavity 21, which then enters the interior of the first branch pipe 26. Simultaneously, the second communication port 23 introduces gas into the interior of the first branch pipe 26, causing the air and gas to mix within the first branch pipe 26. The mixed gas is then delivered to the first nozzle 11 through the first communication port 22.

[0052] Similarly, one end of the second branch pipe 27 communicates with the inner cavity 21, while the other end forms a first communication port 22, which communicates with the second nozzle 12. The second branch pipe 27 also has a second communication port 23. Thus, the air supply member 30 first delivers air to the inner cavity 21, which then enters the interior of the second branch pipe 27 through the inner cavity 21. Simultaneously, the second communication port 23 introduces gas into the interior of the second branch pipe 27, causing the air and gas to mix within the second branch pipe 27. The mixed gas is then delivered to the second nozzle 12 through the first communication port 22.

[0053] Thus, through the above structure, the independent ignition of the first nozzle 11 and the second nozzle 12 can be achieved, and the combustion heating range can be made larger and more uniform during the application process.

[0054] It is understandable that the nozzle group 10 may further include more nozzles, and each nozzle may realize the introduction of air and gas through a corresponding branch pipe. The specific configuration may be adjusted according to actual usage requirements, which will not be elaborated here.

[0055] In some embodiments, the air supply assembly 100 further includes a flow divider 40, which is disposed within the first branch pipe 26 and / or the second branch pipe 27 and is located between the corresponding second communication port 23 and the nozzle assembly 10 along the flow direction of the air and the combustion medium. The flow divider 40 is used to disperse the mixed air and the combustion medium.

[0056] Specifically, the flow divider 40 is a structure capable of dispersing the gas passing through it into multiple branches. The flow divider 40 can be positioned within the first branch pipe 26, the second branch pipe 27, or both. It is understood that the specific position of the flow divider 40 can be adjusted based on the actual amount of gas flowing through the first branch pipe 26 and the second branch pipe 27.

[0057] For ease of understanding, the following explanation will be given using the example of a diverter 40 disposed inside the second branch pipe 27. The diverter 40 is disposed between the second connecting port 23 and the nozzle assembly 10, that is, between the second connecting port 23 and the second nozzle 12. In this manner, air enters the second branch pipe 27 from the third connecting port 24, and gas enters the second branch pipe 27 from the second connecting port 23. The air and gas undergo a first mixing process within the second branch pipe 27 in mutually perpendicular flow directions. After mixing, the air and gas continue to flow along the second branch pipe 27 toward the second nozzle 12, being diverted by the diverter 40 during the flow process. During this diversion process, the air and gas can undergo a second mixing process. This allows the air and gas to be mixed more fully and evenly, further improving thermal efficiency.

[0058] Therefore, by providing the diverter 40, the air and the combustion medium can be dispersed at the position of the diverter 40 and then mixed for the second time, so that the air and the combustion medium are mixed more fully and more evenly, further improving the thermal efficiency.

[0059] In some embodiments, the diverter 40 includes a diverter plate 41 fixed inside the first branch pipe 26 and / or the second branch pipe 27. A plurality of through holes are formed through the diverter plate 41 along the flow direction of the air and the combustion medium, and the through holes are spaced apart from each other.

[0060] Specifically, the diverter piece 41 may be disposed only in the first branch pipe 26 , or only in the second branch pipe 27 , or simultaneously in the first branch pipe 26 and the second branch pipe 27 .

[0061] When the flow dividing member 40 is disposed in the second branch pipe 27 , since the second branch pipe 27 is usually designed as a circular pipe, the flow dividing sheet 41 matches the shape of the second branch pipe 27 and is also designed as a circular sheet structure.

[0062] The diverter piece 41 can be fixed inside the second branch pipe 27 by forming a groove on the inner wall of the second branch pipe 27 and then snapping the diverter piece 41 into the groove to secure the diverter piece 41. Of course, the diverter piece 41 can also be secured inside the second branch pipe 27 by other means, such as gluing or sealing rings, which will not be described in detail here.

[0063] Furthermore, a plurality of through holes are formed on the diverter plate 41, and each through hole is formed along the flow direction of the air and the combustion medium.

[0064] In this way, the air and gas after the first mixing can pass through the through holes, be dispersed in the process, and then be mixed again after passing through the through holes, forming a second mixing.

[0065] Therefore, by providing the diverter piece 41, the air and the combustion medium after the first mixing can be dispersed, so that the air and the combustion medium can be mixed for the second time, making the mixing of the air and the combustion medium more sufficient and more uniform.

[0066] Please also refer to Figure 3 、 Figure 6 as well as Figure 7In some embodiments, all through-holes include a main hole 42 and multiple secondary holes 43. The main hole 42 is coaxially arranged with the diverter plate 41, and the secondary holes 43 are arranged around the outer periphery of the main hole 42. The diverter member 40 also includes a guide shaft 44 coaxial with the main hole 42. The guide shaft 44 has a first end 45 and a second end 46 that are arranged opposite to each other along its own axial direction. The first end 45 passes through the main hole 42. The diameter of the guide shaft 44 gradually increases from the first end 45 to the second end 46.

[0067] Specifically, all through holes can be divided into a main hole 42 and multiple secondary holes 43. The main hole 42 is located at the center of the diverter plate 41, that is, the main hole 42 is coaxial with the diverter plate 41. All secondary holes 43 are evenly spaced along the circumference of the main hole 42, so that all secondary holes 43 can be arranged around the outer periphery of the main hole 42.

[0068] Furthermore, the flow diverter 40 further includes a guide shaft 44, which is coaxially disposed with the main hole 42 and has a diameter that gradually increases from the first end 45 to the second end 46. Thus, the first end 45 of the guide shaft 44 is tapered and passes through the main hole 42.

[0069] As a result, when the air and gas mixture passes through the diverter plate 41, it is first dispersed by the primary holes 42 and the secondary holes 43. Part of the mixed gas passes through the primary holes 42, and part of the mixed gas passes through the corresponding secondary holes 43. The part of the mixed gas that passes through the primary holes 42 will disperse in all directions along the guide shaft 44, thereby contacting and mixing with the gas passing through the secondary holes 43.

[0070] Thus, through the cooperation of the diverter piece 41 and the guide shaft 44, the air and the combustion medium can be mixed for the second time, so that the mixing of the air and the combustion medium is more sufficient and more uniform.

[0071] In some embodiments, the diameters of the secondary holes 43 are not equal.

[0072] Specifically, the diameters of the auxiliary holes 43 are not equal, which specifically means that different auxiliary holes 43 may have different diameters, that is, the sizes of the auxiliary holes 43 are different.

[0073] All the secondary holes 43 surround the outer circumference of the main hole 42, and the diameters of the secondary holes 43 are set to be unequal. When the mixed gas of air and gas passes through the secondary holes 43, a certain speed difference can be formed, which is more conducive to uniform and sufficient mixing of air and gas.

[0074] In some embodiments, the diameter of each secondary hole 43 gradually decreases in a clockwise direction or a counterclockwise direction.

[0075] Specifically, with one of the auxiliary holes 43 being the first one, the diameters of the auxiliary holes 43 decrease in sequence in a clockwise direction or a counterclockwise direction.

[0076] In this way, after the air and the combustion medium are dispersed through the auxiliary holes 43 , they can be further mixed in a clockwise direction or a counterclockwise direction, so that the mixing between the air and the combustion medium is more sufficient and uniform.

[0077] In some embodiments, the diverter 40 further includes a fan blade 47 rotatably connected to the second end 46 of the guide shaft 44 . The fan blade 47 is configured to rotate around the guide shaft 44 driven by the air and combustion medium passing through the diverter plate 41 .

[0078] Specifically, the fan blade 47 is rotatably connected to the second end 46 of the guide shaft 44 , so that the fan blade 47 can rotate around the axial direction of the guide shaft 44 .

[0079] After the air and the combustion medium are dispersed through the auxiliary holes 43, the airflow with a certain speed difference formed can drive the fan blades 47 to rotate. On the one hand, under the rotation of the fan blades 47, the mixing effect between the air and the combustion medium can be further improved; on the other hand, since the airflow drives the fan blades 47 to rotate, the speed of the overall airflow is reduced, thereby making the combustion more stable.

[0080] In some embodiments, the second nozzle 12 is disposed around the outer periphery of the first nozzle 11 .

[0081] Specifically, the second nozzle 12 is disposed around the outer periphery of the first nozzle 11 to form an inner ring fire and an outer ring fire, which can expand the area covered by the combustion.

[0082] Based on the same concept as the above-mentioned gas supply assembly 100 , the present application also provides a gas stove, including the above-mentioned gas supply assembly 100 .

[0083] It can be understood that the gas supply assembly 100 provided in the present application can be used not only in gas stoves, but also in other structures such as integrated stoves and cooking centers, which will not be described in detail here.

[0084] According to one or more embodiments, when the present application is used, the centrifugal fan is turned on, the centrifugal fan draws air from the external environment, and then blows the air from the air outlet 31 into the inner cavity 21, and under the action of the centrifugal fan, the air enters the first branch pipe 26 and the second branch pipe 27, and flows toward the first nozzle 11 and the second nozzle 12.

[0085] At the same time, the second connecting ports 23 on the first branch pipe 26 and the second branch pipe 27 introduce gas into the interior of the first branch pipe 26 and the second branch pipe 27 respectively. The flow direction of the gas is perpendicular to the flow direction of the air blown out of the centrifugal fan, so that the air and gas are mixed for the first time in the first branch pipe 26 and the second branch pipe 27.

[0086] Among them, the first branch pipe 26 is connected to the first nozzle 11 to form an inner ring fire, and the second branch pipe 27 is connected to the second nozzle 12 to form an outer ring fire. The amount of gas in the first branch pipe 26 is less than the amount of gas in the second branch pipe 27. Therefore, the diverter 40 may not be set in the first branch pipe 26, and the diverter 40 may only be set in the second branch pipe 27.

[0087] In this way, air and gas are mixed in the first branch pipe 26 and then flow toward the first nozzle 11 , and are ignited in the first nozzle 11 to form an inner ring fire.

[0088] After the air and gas are mixed for the first time in the second branch pipe 27, the mixed gas is dispersed through the main hole 42 and the auxiliary holes 43 on the diverter plate 41. The airflow passing through the main hole 42 is dispersed to the surroundings under the guidance of the guide shaft 44, forming a certain speed difference between the airflow passing through the auxiliary holes 43. The airflow with the speed difference can drive the fan blades 47 to rotate. In this way, the air and gas are mixed for the second time under the joint action of the diverter plate 41, the guide shaft 44 and the fan blades 47.

[0089] In addition, the airflow speed decreases in the process of driving the fan blades 47 to rotate, thereby making the combustion at the second nozzle 12 more stable.

[0090] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
