Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a gas stove. Background Art

[0002] A gas stove refers to a kitchen appliance that uses petroleum gas, artificial gas, natural gas and other gases as fuel for heating.

[0003] The main components of the combustion system in a gas stove include the ejector tube, the injection device, the burner head and the fire cover. The fuel is injected into the ejector tube through the injection device. During the process of injecting the fuel into the ejector tube, the high-speed flowing fuel will eject the primary air. The primary air and the fuel enter the ejector tube and mix. The primary air can provide oxygen for the fuel combustion.

[0004] However, the natural ability of gas to draw primary air is limited. When the primary air is insufficient, the height of the flame ejected from the fire hole will increase. In order to make the flame better contact with the secondary air and fully burn, the distance between the bottom of the pot and the fire cover needs to be increased, but this will increase the heat dissipated by the flame to the surroundings, resulting in a decrease in the thermal efficiency of the gas stove.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0051] The present application provides a gas stove, such as Figure 1 As shown, Figure 1The present invention provides a schematic diagram of a gas stove 100. The gas stove 100 includes a housing 11, which forms an installation cavity 10 with an opening. The opening is connected to the installation cavity 10, so that other relevant components of the gas stove 100 can be installed in the installation cavity 10 of the housing 11. The housing 11 can provide support for the relevant components installed in the installation cavity 10 thereof, as well as a certain degree of protection, to ensure that the gas stove 100 can work normally.

[0052] On this basis, see Figure 1 The gas stove 100 provided in the present application further includes a burner 2. The burner 2 is the core component of the gas stove 100, and the burner 2 includes a burner head 21, which is disposed in the mounting cavity 10 of the housing 11. The burner head 21 can make the fuel and the primary air mixed in a certain manner, and the primary air and fuel mixed in the burner head 21 flow out from the fire outlet hole of the fire cover covered on the burner head 21, and are ignited to form a flame, which heats the bottom of the pot for the user to cook.

[0053] Continue to see Figure 1 The gas stove 100 provided in the present application further includes a panel 12, which is covered on the opening of the housing 11 and is used to cover the mounting cavity 10 of the housing 11. In this way, the panel 12 can prevent debris or food residues dropped during cooking from falling into the mounting cavity 10 of the housing 11, thereby ensuring that other components arranged in the mounting cavity 10 are not damaged or contaminated, and further ensuring that the gas stove 100 can work normally.

[0054] In this case, if Figure 1 As shown, the panel 12 is also provided with an escape opening 120. The burner head 21 is arranged opposite to the escape opening 120 provided on the panel 12, so that the burner head 21 can be located within the opening range of the escape opening 120 of the panel 12. In this way, when the burner 2 burns fuel to generate flames, the panel 12 will not block the flames generated by the burner 2 burning fuel, ensuring that the burner 2 can work normally, so that the flames can heat the bottom of the pot, so that the user can cook.

[0055] As can be seen from the above, a gas stove 100 provided in an embodiment of the present application may include a shell 11, a panel 12, and a burner 2, which is the core component of the gas stove 100. The burner 2 may be installed in the installation cavity 10 of the shell 11, and then the installation cavity 10 of the shell 11 is covered by the panel 12 to protect other components arranged in the installation cavity 10, to ensure that the burner 2 and other components will not be damaged, thereby ensuring that the gas stove 100 can work normally.

[0056] like Figure 2As shown, the burner provided in the present application further includes an ejector pipe 22. The ejector pipe 22 has a gas inlet 221 and a gas outlet 222 which are arranged opposite to each other. Figure 3 As shown, the gas outlet 222 of the ejector tube 22 is connected to the burner head 21 , and the gas inlet 221 of the ejector tube 22 enables the fuel to enter the ejector tube 22 and then flow into the burner head 21 .

[0057] In order to allow the gas to enter the ejector pipe 22 , the burner 2 also includes a nozzle 23 , one end of which is connected to the gas supply pipeline, and the other end of which is arranged at the gas inlet 221 of the ejector pipe 22 .

[0058] In this way, the fuel is ejected at high speed through the nozzle 23 and enters the ejector tube 22 through the gas inlet 221. In this process, the high-speed flowing gas can eject the air near the gas inlet 221. The ejected air enters the ejector tube 22 together with the high-speed flowing gas as primary air, and then enters the burner head 21 and mixes, and then flows out from the fire hole opened on the fire cover and is ignited to form a flame.

[0059] The process of injecting the high-speed flowing gas into the ejector tube 22 and ejecting air once is called natural ejection. When the gas is ejected from the nozzle at a certain speed and pressure, a high-speed jet is formed. During the flow of this jet, its speed is higher than the surrounding air, and a local negative pressure area is formed near the gas jet, thereby attracting the nearby air, so that the nearby air enters the ejector tube together with the gas jet.

[0060] It should be noted that the amount of primary air will affect the height of the flame at the fire outlet. When the primary air content is high, the height of the flame at the fire outlet will be greater than when the primary air content is low. When the flame height increases, in order to ensure that the fuel is fully burned and the smoke index is qualified, it is necessary to increase the distance between the bottom of the pot and the fire cover, which will increase the loss of flame heat, thereby reducing the thermal efficiency of the gas stove.

[0061] However, the natural injection capacity of the gas jet is limited. When the natural injection of the gas primary air reaches its limit and the primary air still cannot make the gas burn fully, in order to make the gas burn fully and ensure that the smoke gas indicators are qualified, it is necessary to increase the distance between the pot and the fire cover, which will lead to a decrease in the thermal efficiency of the gas stove.

[0062] In order to solve the problem of limited primary air capacity of natural gas injection, Figure 4 As shown, the gas stove provided in the present application further includes a blowing device 3 , and the blowing device 3 is used to add primary air into the ejection tube 22 .

[0063] The air blowing device 3 includes a fan 31, which is used to drive the air flow, so as to force the air to be transported into the ejector pipe 22. In this way, the amount of primary air in the ejector pipe 22 can be increased to ensure that the gas can be fully burned.

[0064] In some embodiments, the fan 31 may be a centrifugal fan. Figure 5 As shown, the fan 31 may include a housing 310, a cavity is formed inside the housing 310, and an air inlet 311 and an air outlet 312 are also provided on the housing 310. Based on this, the fan 31 also includes an impeller and a driving structure arranged in the cavity of the housing 310, wherein the driving structure is used to drive the impeller to rotate. In this way, when the fan 31 is working, the driving structure drives the impeller to rotate, and the high-speed rotating impeller converts mechanical energy into kinetic energy and pressure energy of the gas, so that air enters the cavity of the housing 310 from the air inlet 311 of the housing 310, and then blows out through the air outlet 312 and enters the ejector tube 22, so as to achieve the purpose of replenishing the primary air.

[0065] It should be noted that the fan 31 may also be an axial flow fan, or other forms of fans, which is not limited in the present application.

[0066] Continue to see Figure 4 The air blowing device 3 provided in the present application further includes an air supply assembly 32, which is connected to the ejection pipe 22 and the fan 31. The air supply assembly forms an air duct 320, one end of the air duct 320 is connected to the fan 31, and the other end of the air duct 320 is connected to the ejection pipe 22.

[0067] In this way, the air driven by the fan 31 can be blown into the air duct 320, and then the air is blown into the ejection tube 22 through the air duct 320, thereby achieving the purpose of replenishing the primary air.

[0068] In addition, if Figure 6 As shown, the nozzle 23 is connected to the air supply assembly 32 , and the nozzle 23 is disposed at the other end of the ejector pipe 22 , namely, at the gas inlet 221 of the ejector pipe 22 , through the air supply assembly 32 .

[0069] On this basis, if Figure 6 As shown, a natural injection hole 3200 is also formed on the air supply component 32, one end of the natural injection hole 3200 is connected to the injection pipe 22 (connected to the gas inlet 221 of the injection pipe 22), and the other end is connected to the outside.

[0070] In this way, the gas jet ejected from the nozzle 23 can eject the air near the ejection pipe 22 through the natural ejection hole 3200. Based on this, even if the blower 3 does not work, the gas stove 100 can be guaranteed to work normally. When the blower 3 works, the fan 31 can blow air into the ejection pipe 22. At the same time, the gas jet ejected from the nozzle 23 can also eject primary air. Supplementing the primary air in two ways can effectively increase the amount of primary air and ensure full combustion of the gas.

[0071] Next, the structure of the air supply assembly 32 will be further described in conjunction with the accompanying drawings. Figure 7 As shown, the air supply assembly 32 includes a connecting member 321, and one end of the connecting member 321 is connected to the fan 31. In this way, the fan 31 can allow air to enter the connecting member 321.

[0072] The air supply assembly 32 further includes an air supply member 322, one end of which is connected to the other end of the connecting member 321, and the other end of which is connected to the ejection tube 22. The air supply member 322 is formed with an air duct 320, one end of which is connected to the ejection tube 22, and the other end of which is connected to the connecting member 321.

[0073] In this way, the air in the connecting member 321 can further enter the air supply member 322, and then enter the ejection tube 22 through the air duct 320 on the air supply member 322. The air sucked by the fan 31 first enters the connecting member 321, which can play a buffering role, so that the sucked air enters the air duct 320 more evenly.

[0074] On this basis, see Figure 8 , the axis of the connecting member 321 is perpendicular to the axis of the air supply member 322. In this way, the fan 31 connected to the connecting member 321 can be located on one side of the ejector tube 22 (for example, the left side or the right side of the ejector tube 22), so that when the fan 31 is working, the fan 31 will suck air from one side of the ejector tube 22. In this way, the fan 31 will suck air from the air far away from the gas inlet 221 of the ejector tube 22, but will not suck air from the gas inlet 221 of the ejector tube 22, so as not to interfere with natural ejection.

[0075] In some embodiments of the present application, Fig. 9 As shown, the end of the connecting member 321 close to the air supply member 322 is formed with a first connecting portion 41. Fig.10 As shown, the air supply member 322 is formed with a second connection portion 42 at one end close to the connecting member 321. The first connection portion 41 of the connecting member 321 is connected to the second connection portion 42 of the air supply member 322, so that the connecting member 321 and the air supply member 322 can be connected through the first connection portion 41 and the second connection portion 42.

[0076] In some embodiments, Fig. 9 As shown, the first connecting portion 41 includes a first ear plate 411 and a second ear plate 412, which are spaced apart at one end of the connecting member 321 close to the air supply member 322. Through holes are formed on the first ear plate 411 and the second ear plate 412.

[0077] On this basis, if Fig.10 As shown, the second connection part 42 includes a third ear plate 421 and a fourth ear plate 422. The third ear plate 421 and the fourth ear plate 422 are arranged at intervals at one end of the air supply member 322 close to the connection member 321. The third ear plate 421 and the fourth ear plate 422 are both provided with screw holes.

[0078] Based on this, see Fig.11 , the first ear plate 411 and the third ear plate 421 are arranged opposite to each other, and the second ear plate 412 and the fourth ear plate 422 are arranged opposite to each other. Further, screws are inserted into the through hole of the first ear plate 411 and the screw hole of the third ear plate 421, and the screws are threadedly connected with the threaded holes to ensure the stability of the connection between the first ear plate 411 and the third ear plate 421. The second ear plate 412 and the fourth ear plate 422 are connected in the same way, that is, the second ear plate 412 and the fourth ear plate 422 are connected by screws.

[0079] In other embodiments, the threaded holes formed on the first ear plate 411, the second ear plate 412, the third ear plate 421 and the fourth ear plate 422 may also be through holes. Based on this, two oppositely disposed ear plates may be connected by riveting.

[0080] In some embodiments, the first ear plate 411 and the second ear plate 412 may also be formed with a positioning profile on their circumferences, and the positioning profile is formed by baffles arranged along the circumferences of the first ear plate 411 and the second ear plate 412. In this way, during assembly, the third ear plate 421 may be placed in the positioning profile formed by the baffle on the first ear plate 411. The fourth ear plate 422 may be placed in the positioning profile formed by the baffle on the second ear plate 412. The positioning profile may serve as a guide for easy assembly.

[0081] like Fig.12 As shown, the connecting member 321 includes a first connecting member 3211, one end of which is connected to the fan. The connecting member 321 also includes a second connecting member 3212, which is connected to the other end of the first connecting member 3211, and the other end of the second connecting member 3212 is connected to the air supply member.

[0082] In this way, when the fan 31 is working, the air can be blown into the first connecting piece 3211 and the second connecting piece 3212 of the connecting piece 321 in sequence. Then the air is blown into the air supply piece 322 connected to the second connecting piece 3212, and finally flows into the ejection pipe 22, so as to realize the replenishment of the primary air.

[0083] In addition, it should be noted that the diameter of the first connecting piece 3211 is smaller than the diameter of the second connecting piece 3212. In this way, when air flows from the first connecting piece 3211 into the second connecting piece 3212, the air flow rate will decrease due to the sudden increase in diameter, and its static pressure will increase. In this case, it is beneficial for the air to be more evenly distributed in the second connecting piece 3212 of the connecting piece 321. Furthermore, the air flow entering the air supply piece 322 through the second connecting piece 3212 is also more uniform.

[0084] like Fig.13 As shown, the air supply member 322 includes a mounting plate 3221. The mounting plate 3221 is covered on one end of the ejection tube 22, and an air outlet hole 32210 is opened on the mounting plate 3221. The air outlet hole 32210 is connected to the ejection tube, and the air outlet hole 32210 is also connected to the air duct 320.

[0085] In this way, the mounting plate 3221 is covered on the gas inlet 221 of the ejector tube 22 to seal the gas inlet 221, thereby ensuring that the air blown into the air duct 320 by the fan 31 can enter the ejector tube 22 through the air outlet 32210, thereby achieving the purpose of replenishing primary air.

[0086] like Fig.13 As shown, the air supply member 322 further includes an air guide plate 3222, which is located on a side of the mounting plate 3221 away from the ejection tube 22, and the air guide plate 3222 is connected to the mounting plate 3221. Fig.13 As shown, the air guide plate 3222 is formed with a concave structure, and an air duct 320 is formed between the inner wall of the concave structure of the air guide plate 3222 and the mounting plate 3221. Then, the other end of the second connecting member 3212 of the connecting member 321 is connected to the air duct 320, so that the fan 31 can blow air into the ejection pipe 22.

[0087] In this way, an air duct 320 is formed by the air guide plate 3222 and the mounting plate 3221, so that the fan 31 can blow the primary air into the ejection pipe 22 through the air duct, thereby achieving the purpose of replenishing the primary air.

[0088] It should be noted that the air guide plate 3222 and the mounting plate 3221 can be integrally formed, for example, by casting or die-casting. Alternatively, the air guide plate 3222 and the mounting plate 3221 can be separately formed and then connected and assembled by welding or bonding.

[0089] Continue to see Fig.13 The air supply member 322 further includes a connecting plate 3224, which is perpendicular to the axis of the air duct 320 and is connected to the mounting plate 3221 and the air guide plate 3222. Fig.14 As shown, the connecting plate 3224 is formed with a connecting air duct 32240 , one end of the connecting air duct 32240 is connected to the air duct 320 , and the other end of the connecting air duct 32240 is connected to the connecting member 321 .

[0090] In this way, the connecting piece 321 is connected to the air duct 320 through the connecting plate, so that the wind blown out by the fan passes through the connecting piece 321 in sequence, and after being decelerated and pressurized in the connecting piece, it continues to flow through the connecting air duct 32240 and then enters the air duct 320, and finally enters the ejector pipe 22, thereby realizing the replenishment of air.

[0091] like Fig.15 As shown, in some embodiments of the present application, a windshield 3223 is formed on the surface of the mounting plate 3221 close to the ejection tube 22, and the windshield 3223 is annular. Fig.16 The windshield 3223 extends into the ejector tube 22, and the windshield 3223 abuts against the inner wall of the ejector tube 22. The contour shape of the windshield 3223 is the same as the contour shape of the gas inlet 221 of the ejector tube 22. The windshield 3223 and the gas inlet 221 of the ejector tube 22 are nested, and the outer wall surface of the windshield 3223 abuts against the inner wall surface of the gas inlet 221 of the ejector tube 22.

[0092] In this case, the above-mentioned wind shield 3223 can play a certain sealing role to ensure that the air blown into the air duct 320 by the fan 31 will not flow out from the gap that may exist between the mounting plate 3221 and the ejection tube 22, and ensure that the fan 31 can blow air into the ejection tube 22 to play a role in replenishing the primary air.

[0093] In addition, since the contour shape of the wind shield 3223 is the same as the contour shape of the gas inlet 221 of the ejector tube 22, and the wind shield 3223 and the gas inlet 221 of the ejector tube 22 are nested, when the fixing mounting plate 3221 is assembled on the ejector tube 22, the wind shield 3223 can also play a certain guiding role, which is convenient for installation.

[0094] As can be seen from the above, the nozzle 23 is disposed at the gas inlet 221 of the ejector tube 22 through the air supply assembly 32. Next, how the nozzle 23 is disposed at the gas inlet 221 of the ejector tube 22 through the air supply assembly 32 is described in conjunction with the accompanying drawings.

[0095] like Fig.13 As shown, the mounting plate 3221 is provided with a first mounting hole 230, and the first mounting hole 230 is used to mount the nozzle 23. The first mounting hole 230 is a threaded hole, based on which the nozzle 23 can be connected to the mounting plate 3221 by threaded connection, so as to be arranged at the gas inlet 221 of the ejector pipe 22 through the mounting plate 3221.

[0096] It should be noted that the air outlet 32210 and the first mounting hole 230 formed on the mounting plate 3221 are both located on the inner side of the wind shielding plate 3223 .

[0097] In addition, it should be noted that the natural injection hole 3200 is opened around the first mounting hole 230. In this way, when the natural injection hole 3200 is opened around the first mounting hole 230, it can be ensured that when the nozzle 23 sprays gas, the gas jet can inject primary air through the natural injection hole 3200. Therefore, natural injection can be performed while the fan 31 blows primary air into the injection pipe 22.

[0098] In some embodiments of the present application, the number of the natural ejection holes 3200 is multiple, and the multiple natural ejection holes 3200 are spaced around the first mounting hole 230. The number of the natural ejection holes 3200 can be 6 (see Figure 6 ), the six natural ejection holes 3200 are evenly opened on the outer periphery of the first mounting hole 230. For example, the six natural ejection holes 3200 can be evenly opened on the left and right sides of the first mounting hole 230.

[0099] In this way, when the nozzle 23 installed at the first installation hole 230 sprays gas, the high-speed gas jet can inject primary air through the multiple natural injection holes 3200 spaced apart on the periphery of the first installation hole 230. The multiple natural injection holes 3200 can evenly inject the air near the first installation hole 230 into the injection pipe 22 by the high-speed gas jet.

[0100] like Fig.17 As shown, in some embodiments of the present application, the air supply assembly 32 further includes a porous plate 4, which can be arranged in the connecting air duct 32240 of the connecting plate 3224 (see Fig.14 The porous plate 4 is provided with a plurality of through holes 40, and the through holes 40 are evenly provided on the porous plate 4, or the through holes 40 can also be unevenly provided.

[0101] In this way, when the fan 31 blows air into the connecting pipe 321 of the air supply component 32, when the air in the connecting plate 3224 flows through the porous plate 4, the air will contact the porous plate 4, and then continue to flow into the air duct 320 through the through hole 40. The porous plate 4 can play a certain role in slowing down the flow, so that the air flow rate blown into the air duct 320 by the fan 31 will not be too fast, and it is conducive to more uniform distribution of air in the air duct 320. Further, the primary air supplemented by the fan 31 can be blown into the ejection pipe 22 more evenly, so as to avoid the primary air supplemented by the fan 31 from affecting the gas ejected from the nozzle 23, and ensure that the gas jet has sufficient energy for natural ejection.

[0102] In other embodiments of the present application, Fig.18 As shown, the porous plate 4 can also be arranged in the connecting pipe 321. In this way, when the air flows into the connecting pipe 321 and flows through the porous plate 4, the porous plate 4 can play a slow flow role, so that the airflow velocity blown into the connecting pipe 321 by the fan 31 is reduced and the static pressure is enhanced, so that the air can be better distributed in the connecting pipe 321, and then the air is more evenly distributed when entering the air duct 320 of the air supply component 32. Furthermore, the primary air supplemented by the fan 31 can be blown into the ejection pipe 22 more evenly, so as to avoid the primary air supplemented by the fan 31 from affecting the gas ejected from the nozzle 23, and ensure that the gas jet has enough energy for natural ejection.

[0103] In some embodiments of the present application, the porous plate 4 may also be disposed in the first connecting piece 3211 and the second connecting piece 3212 of the connecting pipe 321. In this way, when the air blown in by the fan 31 flows through the porous plate 4 in the first connecting piece 3211 and the porous plate 4 in the second connecting piece 3212, the air blown into the connecting pipe 321 by the fan 31 can be slowed down twice, so that the air blown into the connecting pipe 321 by the fan 31 can be slowed down better, so that the air can flow from the connecting pipe 321 into the air duct 320 of the air supply pipe 322 more evenly.

[0104] like Fig.17 As shown, in order to install the mounting plate 3221 of the air supply member 322 of the air supply assembly 32 on the ejection tube 22 (see Figure 4 ), a second mounting hole 50 is also provided on the mounting plate 3221. Based on this, in order to connect the mounting plate 3221 with the ejection tube 22, the gas stove 100 further includes a fixing member, which is penetrated in the second mounting hole 50 and connected with the ejection tube 22.

[0105] In some embodiments, the second mounting hole 50 provided on the mounting plate 3221 may be a through hole, based on which a threaded hole corresponding to the second mounting hole 50 may also be provided on the ejector tube 22. The fixing member may be a screw, so that the fixing member may be screwed into the second mounting hole 50 and the threaded hole provided on the ejector tube 22, thereby installing the mounting plate 3221 on the ejector tube 22.

[0106] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0107] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
