Description

Technical Field

[0001] This application relates to home appliance technology, and more particularly to a gas stove. Background Technology

[0002] Gas stoves are kitchen appliances that use gaseous fuels such as liquefied petroleum gas, manufactured gas, and natural gas for direct-fire heating.

[0003] In related technologies, gas stoves include a housing and a burner. The housing includes a bottom shell and a panel. The burner is installed on the inner bottom wall of the bottom shell and partially inserted into the panel. The burner nozzle is connected to the gas pipe through a pipeline.

[0004] However, gas stoves have poor combustion performance. Summary of the Invention

[0005] This application provides a gas stove with good combustion performance.

[0006] This application provides a gas stove, including:

[0007] The housing has a mounting cavity;

[0008] The pressurization chamber is located inside the installation cavity. The pressurization chamber has an inner cavity and an air inlet that communicates with the inner cavity.

[0009] The burner has a portion of the burner located within the inner cavity, and the burner is equipped with an air inlet that communicates with the inner cavity.

[0010] The fan is connected to the air inlet and is configured to deliver air from outside the pressurization chamber to the inner cavity through the air inlet so that the air pressure inside the inner cavity is greater than atmospheric pressure.

[0011] In this way, by setting up a pressurized chamber surrounding the burner, the pressurized chamber can serve as a heat insulation unit. Less heat from the flame is transferred to the bottom of the burner and more to the cookware, thus improving the thermal efficiency of the gas stove. Furthermore, it helps reduce heat transfer to other components within the casing, extending their lifespan. Moreover, as air enters the pressurized chamber through the air inlet and inner cavity, the temperature of the primary air is raised by the heat within the pressurized chamber, further improving the gas stove's thermal efficiency. Additionally, under the action of the fan, the inner cavity of the pressurized chamber is under positive pressure, allowing more air to enter the burner through the air inlet and mix with the gas. In other words, compared to atmospheric pressure, this embodiment facilitates an increase in primary air, resulting in better combustion.

[0012] In some embodiments, the opening area of ​​the air inlet is larger than the opening area of ​​the air inlet.

[0013] In this way, the opening area of ​​the air inlet is larger than that of the air inlet, resulting in a greater amount of air entering the pressurization chamber than entering the burner, thus making the pressure inside the pressurization chamber greater than atmospheric pressure. Moreover, pressure adjustment is achieved by using a fan and the size of the opening area, resulting in a simple overall structure and lower manufacturing difficulty.

[0014] In some embodiments, the opening area of ​​the air inlet is greater than 1.02 times the opening area of ​​the air inlet, and the opening area of ​​the air inlet is less than 1.05 times the opening area of ​​the air inlet.

[0015] When the opening area of ​​the air inlet is less than 1.02 times the opening area of ​​the air inlet, the difference between the amount of air entering the pressurization chamber and the amount of air entering the burner is small, the pressure inside the pressurization chamber is small, the increase in primary air is small, and the combustion effect of the gas stove is poor.

[0016] When the opening area of ​​the air inlet is more than 1.05 times the opening area of ​​the air inlet, the difference between the amount of air entering the pressurization chamber and the amount of air entering the burner is large. Excess air can easily lower the temperature of the burner, and the lower temperature of the first air is not conducive to improving the thermal efficiency of the gas stove.

[0017] In some embodiments, the air pressure inside the pressurization chamber is greater than 1.02 times the atmospheric pressure, and less than 1.05 times the atmospheric pressure.

[0018] When the air pressure inside the pressurization chamber is less than 1.02 times the atmospheric pressure, the amount of air entering the pressurization chamber is small, the increase in primary air is small, and the combustion effect of the gas stove is poor.

[0019] When the air pressure inside the pressurization chamber is greater than 1.05 times the atmospheric pressure, a large amount of air enters the pressurization chamber. The excess air can easily lower the temperature of the burner, and the lower temperature of the initial air is not conducive to improving the thermal efficiency of the gas stove.

[0020] In some embodiments, the fan is connected to the outer wall of the pressurization chamber.

[0021] In this way, compared to placing the fan inside the pressurization chamber, the fan is connected to the outer wall of the pressurization chamber, and the distance between the fan and the burner is larger, making it less likely to be damaged by the heat of the burner.

[0022] In some embodiments, the burner includes:

[0023] The furnace body, with part of it located inside the cavity;

[0024] At least one nozzle is connected to the furnace body and located in the inner cavity. The nozzle is provided with an air inlet, which is located on the side of the furnace body away from the air inlet.

[0025] In this way, primary air is drawn into the pressurization chamber from the air inlet by the ejector action of the fan and nozzles. As the air flows inside the pressurization chamber, it passes through the high-temperature area of ​​the furnace, carrying away some of the heat and thus cooling the furnace. Moreover, the primary air is heated through heat exchange, thereby improving the thermal efficiency of the gas.

[0026] In some embodiments, it also includes:

[0027] The ventilation line is connected to the nozzle. Part of the ventilation line is located inside the cavity, and the other part of the ventilation line is located outside the pressurization chamber through the clearance opening in the pressurization chamber body.

[0028] The first seal is located between the inner wall of the clearance opening and the vent pipe.

[0029] In this way, by setting the first sealing element, the gap between the vent pipe and the inner wall of the clearance opening can be sealed, which helps to improve the sealing performance and the heat insulation effect.

[0030] In some embodiments, the pressurization chamber includes:

[0031] The bottom plate is connected to the inner bottom wall of the shell, and the furnace body is connected to the bottom plate and located on top of the bottom plate;

[0032] The enclosure is connected to the bottom plate and is installed around the perimeter of the furnace body. The air inlet is located on the enclosure, and the fan is connected to the enclosure.

[0033] The cover plate is placed on the side of the enclosure away from the bottom plate, and the upper part of the furnace body is inserted into the cover plate.

[0034] In this way, the fan can be installed on the enclosure panel, and the fan has little impact on the height dimension of the pressurization chamber, so the height dimension of the pressurization chamber can be smaller.

[0035] In some embodiments, it also includes:

[0036] The controller, located inside the housing, is electrically connected to the fan and is configured to control the fan speed according to the gear position.

[0037] In this way, different firepower levels can be matched to meet the demand for primary air.

[0038] In some embodiments, it also includes:

[0039] A temperature sensor is located inside the pressurization chamber and is configured to detect the temperature of the internal cavity.

[0040] The temperature sensor is electrically connected to the controller, which is configured to control the fan to run when the gas stove stops running and the temperature is greater than a preset value.

[0041] In this way, when the gas stove stops running, the temperature inside the pressurization chamber can be monitored. If the temperature is too high, the fan can be controlled to cool the burner, thereby reducing the overall temperature of the gas stove and improving the user experience. Attached Figure Description

[0066] As described in the background section, a gas stove includes a housing and a burner. The housing comprises a bottom shell and a panel. The burner is mounted on the inner bottom wall of the bottom shell and partially inserted into the panel. The burner nozzle is connected to a gas pipe via a pipeline. When the flame at the top of the burner burns, some of the heat from the flame is transferred along the burner to the bottom of the burner and to other components within the housing, such as electrical controls and the valve body.

[0067] Therefore, the greater the temperature difference between the top and bottom of the burner, the more heat will be transferred to the bottom of the burner and less heat will be transferred to the cookware, resulting in lower thermal efficiency of the gas stove. Furthermore, heat transferred to other components inside the casing can easily affect their lifespan.

[0068] To address the aforementioned technical problems, this application incorporates a pressurized chamber that encloses the burner, thereby providing insulation and heat protection. This reduces the amount of heat transferred from the flame to the bottom of the burner and increases the amount transferred to the cookware, thus improving the thermal efficiency of the gas stove. Furthermore, it helps reduce heat transfer to other components within the casing.

[0069] Furthermore, the inventors discovered that due to the encapsulation of the pressurized chamber, the amount of primary air in the burner is relatively small, resulting in poor combustion performance.

[0070] To address the aforementioned technical problems, in the embodiments of this application, a fan is installed, connected to the air inlet of the pressurization chamber. The fan delivers air from outside the pressurization chamber into the inner cavity through the air inlet, thereby increasing the air pressure inside the pressurization chamber to be greater than atmospheric pressure. In other words, the inner cavity of the pressurization chamber is under positive pressure. Compared to the atmospheric pressure state in related technologies, the amount of primary air in the gas stove of this application embodiment can be increased, resulting in better combustion performance.

[0071] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application.

[0077] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0078] Figure 1 This is a schematic diagram of the structure of the gas stove provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of a gas stove provided in an embodiment of this application after removing part of the outer casing.

[0079] See Figure 1 and Figure 2 As shown in the figure, this application provides a gas stove.

[0080] The gas stove can be an integrated gas stove or a freestanding gas stove.

[0081] In some embodiments, the gas cooker includes a housing 100.

[0082] The housing 100 is a hollow container structure, and the exterior of the housing 100 forms the outer shell of the gas stove. The internal space of the housing 100 forms an installation cavity.

[0083] In some embodiments, the gas cooker includes a burner 200.

[0084] The burner 200 is connected to the gas through a pipeline. The gas and air are mixed in the burner 200, and the mixture is ignited to produce a flame.

[0085] In some embodiments, the burner 200 is provided with an air inlet 210. Primary air enters the burner 200 through the air inlet 210.

[0086] In some embodiments, the burner 200 is provided with a gas inlet 240. Gas enters the burner 200 through the gas inlet 240.

[0087] Figure 3 This is a schematic diagram of the structure of the pressurization chamber, burner, and fan in the gas stove provided in the embodiments of this application. Figure 4 for Figure 3 Exploded view.

[0088] See Figure 3 and Figure 4 As shown, in some embodiments, the gas stove includes a pressurized chamber 300.

[0089] In some embodiments, the pressurization chamber 300 is located within the housing 100.

[0090] Figure 5 for Figure 3 A schematic diagram of the structure after removing the flame cap. Figure 6 This is a schematic diagram of the structure of the fan, part of the pressurization chamber, and part of the burner in the gas stove provided in the embodiments of this application. Figure 7 for Figure 6 Another structural diagram from another angle, Figure 8 for Figure 6 Another structural diagram from this angle.

[0091] See Figures 5 to 8 As shown, in some embodiments, the pressurization chamber 300 is provided with an inner cavity 310.

[0092] In some embodiments, the pressurization chamber 300 is provided with an air inlet 320, which is connected to the inner cavity 310.

[0093] It should be noted that external air can enter the inner cavity 310 of the pressurization chamber 300 through the air inlet 320.

[0094] In some embodiments, a portion of the burner 200 is located within the cavity 310.

[0095] In some embodiments, a portion of the burner 200 is located in the inner cavity 310, and a portion of the burner 200 near the top is inserted into the pressurization chamber 300.

[0096] It should be noted that the burner 200 near the top needs to be located outside the pressurization chamber 300 and outside the housing 100.

[0097] Understandably, by setting up the pressurization chamber 300, which surrounds the burner 200, the pressurization chamber 300 can serve a heat insulation function. Less heat from the flame is transferred to the bottom of the burner 200, and more is transferred to the cookware, thus improving the thermal efficiency of the gas stove. Furthermore, it helps reduce heat transfer to other components within the casing 100, extending their lifespan. Further, the pressurization chamber 300 helps reduce the overall temperature rise of the gas stove. Moreover, as air enters the pressurization chamber 300 through the air inlet 320 and the inner cavity 310, the temperature of the primary air can be increased by the heat within the pressurization chamber 300, thereby improving the thermal efficiency of the gas stove.

[0098] In some embodiments, the burner 200 is provided with an air inlet 210, which communicates with the inner cavity 310.

[0099] External air can enter the inner cavity 310 of the pressurization chamber 300 through the air inlet 320, and then enter the burner 200 through the air inlet 210. This is the primary air mentioned above.

[0100] In some embodiments, the gas stove includes a fan 400. The fan 400 is used to deliver outside air through the air inlet 320 to the inner cavity 310 of the pressurization chamber 300, thereby increasing the pressure in the inner cavity 310.

[0101] In some embodiments, the fan 400 is connected to the air inlet 320.

[0102] The fan 400 is configured to deliver air from outside the pressurization chamber 300 to the inner cavity 310 through the air inlet 320, so that the air pressure inside the pressurization chamber 300 is greater than atmospheric pressure.

[0103] Understandably, the positive pressure state within the chamber 310 of the pressurization chamber 300 facilitates the entry of more air through the air inlet 210 into the burner 200 for mixing with the combustion gas. In other words, compared to atmospheric pressure, this embodiment promotes an increase in primary air, resulting in better combustion performance.

[0104] Furthermore, when the blower enters the pressurization chamber 300, the airflow causes the cold air to carry away heat from the burner 200 as it passes through it, thus increasing the temperature of the primary air and improving thermal efficiency. The fan 400 also reduces the temperature rise of the burner 200 and the outer wall of the pressurization chamber 300, thereby minimizing the impact on external electrical components and extending their lifespan.

[0105] It should be noted that external electrical components can include valve bodies, rubber gaskets, pulse generators, control devices, etc.

[0106] Among related technologies, many forced-air combustion methods rely on interfering with air-fuel mixing to replenish air, resulting in complex control methods.

[0107] It is understandable that the air pressure inside the pressurized chamber 300 in this application is greater than atmospheric pressure. Compared with the forced combustion in related technologies, since it only increases the pressure inside the chamber and does not directly interfere with the mixing of air and fuel, it does not need to consider the control of the air-fuel ratio and does not require complex algorithms and program control. It is simpler than the forced combustion technology in related technologies.

[0108] In some embodiments, the fan 400 is connected to the outer wall of the pressurization chamber 300. In this way, compared to placing the fan 400 inside the pressurization chamber 300, the fan 400 is connected to the outer wall of the pressurization chamber 300, and the distance between the fan 400 and the burner 200 is larger, making it less likely to be damaged by the heat of the burner 200.

[0109] Figure 9 This is a schematic diagram of the structure of the stove body and nozzle in the gas stove provided in the embodiment of this application.

[0110] See Figure 8 and Figure 9 As shown, in some embodiments, the burner 200 includes a furnace body 220.

[0111] In some embodiments, a portion of the furnace body 220 is located within the inner cavity 310 of the pressurization chamber 300.

[0112] Specifically, the top of the furnace body 220 is inserted into the pressurization chamber body 300.

[0113] In some embodiments, the burner 200 includes at least one nozzle 230.

[0114] In some embodiments, the nozzle 230 is located in the inner cavity 310 of the pressurization chamber 300.

[0115] In some embodiments, the nozzle 230 is connected to the furnace body 220, the nozzle 230 is located in the inner cavity 310, and the nozzle 230 is provided with an air inlet 210, which is located on the side of the furnace body 220 away from the air inlet 320.

[0116] In this way, through the ejection action of the fan 400 and nozzle 230, primary air is introduced from the air inlet 320 into the pressurization chamber 300. As the introduced air flows inside the pressurization chamber 300, it passes through the high-temperature area of ​​the furnace body 220, carrying away some heat and thus cooling the furnace body 220. Furthermore, by heating the primary air through heat exchange, the thermal efficiency of the gas combustion is improved. In other words, this embodiment uses the pressurization chamber 300 to enclose the furnace body 220, achieving better insulation and altering the convection path of the primary air, thereby improving thermal efficiency, reducing temperature rise, and ultimately enhancing the user experience.

[0117] See Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the burner 200 includes a flame cap 250.

[0118] In some embodiments, the burner cap 250 is disposed on the top of the furnace body 220.

[0119] In some embodiments, the flame cap 250 is located outside the pressurization chamber 300 and outside the housing 100. In this way, the pressurization chamber 300 is less likely to affect the installation and use of the flame cap 250.

[0120] In some embodiments, the number of nozzles 230 is at least one. For example, the number of nozzles 230 may be one, two, or more.

[0121] In some embodiments, the number of flame caps 250 is at least one. For example, the number of flame caps 250 may be one, two, or more.

[0122] In some embodiments, the number of flame covers 250 is at least two, and the at least two flame covers 250 include an inner flame cover and an outer flame cover, with the inner flame cover located within the area enclosed by the outer flame cover.

[0123] In some embodiments, the number of nozzles 230 is at least two, and the at least two nozzles 230 include an inner nozzle 231 and an outer nozzle, which are spaced apart along the periphery of the burner head body.

[0124] In some embodiments, the inner nozzle 231 is connected to the furnace body 220, and the inner nozzle 231 and the inner fire cover are connected through the furnace body 220.

[0125] In some embodiments, the outer nozzle 232 is connected to the furnace body 220, and the outer nozzle 232 and the outer flame cap are connected through the furnace body 220.

[0126] In some embodiments, the air inlet 320 is located on the side of the outer nozzle 232 away from the furnace body 220.

[0127] It is understandable that the external nozzle 232 has a large load, and the air inlet 320 is located on the side of the external nozzle 232 away from the furnace body 220, which is conducive to more and higher temperature primary air entering the external nozzle 232 and improving thermal efficiency.

[0128] Figure 10 This is a schematic diagram of the nozzle structure in a gas stove provided in an embodiment of this application. Figure 11 for Figure 10 A structural diagram from another angle.

[0129] See Figure 10 and Figure 11 As shown, in some embodiments, the nozzle 230 includes a nozzle body 233.

[0130] The nozzle body 233 has an air passage. The nozzle body 233 is connected to the furnace body 220.

[0131] In some embodiments, one end of the nozzle body 233 along the extending direction is provided with an opening. The opening communicates with the air passage.

[0132] In some embodiments, the nozzle 230 includes a connecting structure 234, which communicates with the furnace body 220. The connecting structure 234 is used to communicate with external gas.

[0133] In some embodiments, the connecting structure 234 is located in the opening of the nozzle body 233, that is, the connecting structure 234 partially obstructs the opening. A gas inlet 240 is disposed on the connecting structure 234. The unobstructed opening of the connecting structure 234 forms an air inlet 210.

[0134] See Figure 11 As shown, air inlets 210 are located on both sides of the connecting structure 234.

[0135] See Figure 6 and Figure 7 As shown, in some embodiments, the gas cooker includes a gas inlet pipe 500.

[0136] The ventilation pipe 500 is connected to the nozzle 230.

[0137] Specifically, the vent pipe 500 can be connected to the connection structure 234. Gas enters the nozzle 230 through the vent pipe 500.

[0138] In some embodiments, part of the ventilation pipe 500 is located in the inner cavity 310, and another part of the ventilation pipe 500 is located outside the pressurization chamber 300 via the clearance opening 330 in the pressurization chamber 300.

[0139] In some embodiments, the gas cooker includes a first seal 600.

[0140] The first sealing element 600 is located between the inner wall of the clearance opening 330 and the vent pipe 500.

[0141] It is understandable that by setting the first sealing element 600, the gap between the vent pipe 500 and the inner wall of the clearance opening 330 can be sealed, which helps to improve the sealing performance and the heat insulation effect.

[0142] In some embodiments, the number of first seals 600 may be equal to the number of clearance openings 330, and the first seals 600 and clearance openings 330 are provided in a one-to-one correspondence.

[0143] For example, the first seal 600 may be made of rubber or sponge.

[0144] Figure 12 This is a schematic diagram of the structure of the pressurization chamber in the gas stove provided in this embodiment of the application after removing the cover plate. Figure 13 for Figure 12 Another structural diagram from another angle.

[0145] See Figure 12 and Figure 13 As shown, in some embodiments, the pressurization chamber 300 includes a base plate 340.

[0146] The bottom plate 340 is connected to the inner bottom wall of the shell 100, and the furnace body 220 is connected to the bottom plate 340 and located on top of the bottom plate 340.

[0147] In some embodiments, the pressurization chamber 300 includes a surrounding panel 350.

[0148] The surrounding plate 350 is connected to the bottom plate 340 and is arranged around the periphery of the furnace body 220.

[0149] In some embodiments, the air inlet 320 is disposed on the enclosure 350.

[0150] In some embodiments, the air inlet 320 includes a plurality of spaced-apart air intake holes. This provides better dust protection compared to having a single, larger air intake hole.

[0151] The air inlet can be circular or rectangular.

[0152] In some embodiments, the clearance 330 is provided on the enclosure 350.

[0153] The clearance opening 330 is located on the side of the nozzle 230 away from the furnace body 220. This facilitates the arrangement of the ventilation pipe 500 and reduces the bends in the ventilation pipe 500.

[0154] In some embodiments, the shape of the clearance opening 330 may match the cross-sectional shape of the vent duct 500.

[0155] For example, the clearance 330 can be circular or rectangular.

[0156] In some embodiments, the center point of the clearance port 330 is collinear with the axis of the nozzle 230. This facilitates the installation of the venting duct 500.

[0157] In some embodiments of this application, the enclosure 350 includes a plurality of flat plates and curved plates connected end to end. This allows the enclosure 350 to occupy a relatively small space.

[0158] The number of tablets must be at least one. That is, the number of tablets can be one, two, or more.

[0159] The number of curved plates can be zero, one, two, or more.

[0160] It should be noted that the number and arrangement order of the flat plates and curved plates can be set according to the space inside the housing 100, and this embodiment does not make specific limitations here.

[0161] It should be noted that the size of the flat plate and the size and curvature of the curved plate can be set according to the space inside the housing 100, and this embodiment does not make specific limitations here.

[0162] The number of nozzles 230 is at least one. For example, the number of nozzles 230 can be one, two, or more.

[0163] The number of clearance ports 330 is at least one. The number of clearance ports 330 can be the same as the number of nozzles 230. At least one clearance port 330 is provided in a one-to-one correspondence with at least one nozzle 230.

[0164] The nozzle 230 is positioned opposite the flat plate, meaning that the flat plate is located on the side of the nozzle 230 away from the furnace body 220. The clearance opening 330 is located on this flat plate.

[0165] In some embodiments, the extended plane of the plate with the clearance 330 is parallel to the end face of the corresponding nozzle 230 away from the furnace body 220. This facilitates the installation of the ventilation pipe 500 and reduces the bends in the ventilation pipe 500.

[0166] In some embodiments, the number of nozzles 230 can be one, and the number of plates can be one or more. In some embodiments, the number of nozzles 230 can be two, and the number of plates can be two or more. That is, the number of plates is not less than the number of nozzles 230.

[0167] In some embodiments, the fan 400 is connected to the enclosure 350. In this way, the fan 400 can be mounted on the enclosure 350, and the fan 400 has little impact on the height dimension of the pressurization chamber 300, so the height dimension of the pressurization chamber 300 can be smaller.

[0168] In some embodiments, the base plate 340 and the surrounding plate 350 are integrally formed, which helps to improve the overall strength.

[0169] In some embodiments, the pressurization chamber 300 includes a cover plate 360.

[0170] The cover plate 360 ​​is placed on the side of the enclosure plate 350 away from the bottom plate 340, and the upper part of the furnace body 220 is inserted on the cover plate 360.

[0171] In some embodiments, the cover plate 360 ​​can be fixed to the enclosure plate 350 by screws.

[0172] In some embodiments, the gas stove includes a second seal 700 located between the stove body 220 and the cover plate 360. The second seal 700 abuts against the cover plate 360 ​​and against the end face of the burner head body.

[0173] The shape of the second seal 700 matches the end face shape of the furnace body 220. This results in a larger sealing area, which helps to improve the sealing effect.

[0174] Specifically, the cover plate 360 ​​is provided with mounting holes 361, and the top of the furnace body 220 is inserted into the mounting holes 361.

[0175] The second sealing element 700 can be fitted onto the furnace body 220 near the top.

[0176] For example, the second seal 700 may be made of rubber. The second seal 700 may be in the shape of a flat plate.

[0177] Understandably, by setting the second seal 700, air can be effectively prevented from flowing through the gap between the end face of the furnace body 220 and the cover plate 360.

[0178] In some embodiments, the gas stove includes a heat insulation component 800, which is disposed on the outer wall of the pressurization chamber 300. This helps to improve the heat insulation effect of the pressurization chamber 300.

[0179] It should be noted that the pressurization chamber 300 and the burner 200 can be assembled into a modular module, which facilitates installation.

[0180] In some embodiments, the opening area of ​​the air inlet 320 is larger than the opening area of ​​the air inlet 210.

[0181] It is understandable that the opening area of ​​the air inlet 320 is larger than that of the air inlet 210, resulting in a greater amount of air entering the pressurization chamber 300 than entering the burner 200, thus causing the pressure inside the pressurization chamber 300 310 to be greater than atmospheric pressure. Moreover, pressure adjustment is achieved by using the fan 400 and the size of the opening area, resulting in a simple overall structure and lower manufacturing difficulty.

[0182] In some other embodiments, the opening area of ​​the air inlet 320 may be equal to the opening area of ​​the air inlet 210. A sealing element can be provided to open or close the air inlet 210. During the initial stage of operation of the fan 400, the air inlet 210 is closed using the sealing element, thereby increasing the pressure inside the pressurization chamber 300 to greater than atmospheric pressure. Once the pressure inside the pressurization chamber 300 exceeds atmospheric pressure, the sealing element can open the air inlet 210.

[0183] In some embodiments, the opening area of ​​the air inlet 320 is greater than 1.02 times the opening area of ​​the air inlet 210.

[0184] When the opening area of ​​the air inlet 320 is less than 1.02 times the opening area of ​​the air inlet 210, the difference between the amount of air entering the pressurization chamber 300 and the amount of air entering the burner 200 is small, the pressure in the inner cavity 310 of the pressurization chamber 300 is small, the increase in primary air is small, and the combustion effect of the gas stove is poor.

[0185] In some embodiments, the opening area of ​​the air inlet 320 is less than 1.05 times the opening area of ​​the air inlet 210.

[0186] When the opening area of ​​the air inlet 320 is more than 1.05 times the opening area of ​​the air inlet 210, the difference between the amount of air entering the pressurization chamber 300 and the amount of air entering the burner 200 is large. Excess air can easily lower the temperature of the burner 200. The lower temperature of the first air is not conducive to improving the thermal efficiency of the gas stove.

[0187] In some embodiments, the opening area of ​​the air inlet 320 is 1.02-1.05 times the opening area of ​​the air inlet 210.

[0188] In some embodiments, the opening area of ​​the air inlet 320 is 1.03-1.05 times the opening area of ​​the air inlet 210.

[0189] In some embodiments, the opening area of ​​the air inlet 320 is 1.02-1.04 times the opening area of ​​the air inlet 210.

[0190] In some embodiments, the opening area of ​​the air inlet 320 is 1.03 times or 1.04 times the opening area of ​​the air inlet 210.

[0191] It should be noted that, see Figure 13 As shown, the opening area of ​​the air inlet 320 is the sum of the projected areas of the air inlets 320 on the plane shown in the figure on the pressurization chamber 300. See also Figure 11 As shown, the opening area of ​​air inlet 210 is the projected area of ​​air inlet 210 on the plane shown. It can be understood that when the number of nozzles 230 is at least two, the opening area of ​​air inlet 210 is the sum of the projected areas of air inlet 210 on each nozzle 230.

[0192] In some embodiments, the air pressure inside the pressurized chamber 300 is greater than 1.02 times the atmospheric pressure.

[0193] When the air pressure inside the pressurization chamber 300 is less than 1.02 times the atmospheric pressure, the amount of air entering the pressurization chamber 300 is small, the increase in primary air is small, and the combustion effect of the gas stove is poor.

[0194] In some embodiments, the air pressure inside the pressurized chamber 300 is less than 1.05 times the atmospheric pressure.

[0195] When the air pressure inside the pressurization chamber 300 is greater than 1.05 times the atmospheric pressure, a large amount of air enters the pressurization chamber 300. The excess air can easily lower the temperature of the burner 200. The lower temperature of the first air is not conducive to improving the thermal efficiency of the gas stove.

[0196] In some embodiments, the air pressure inside the pressurized chamber 300 is 1.02-1.05 times atmospheric pressure.

[0197] In some embodiments, the air pressure inside the pressurized chamber 300 is 1.03-1.05 times atmospheric pressure.

[0198] In some embodiments, the air pressure inside the pressurized chamber 300 is 1.02-1.04 times atmospheric pressure.

[0199] In some embodiments, the air pressure inside the pressurized chamber 300 is 1.03 times or 1.04 times atmospheric pressure.

[0200] In some embodiments, the gas cooktop includes a controller.

[0201] The controller is located inside the housing 100 and is electrically connected to the fan 400. The controller is configured to control the speed of the fan 400 according to the gear position.

[0202] Specifically, when the gas stove's setting is increased, the fan speed increases by 400. This allows for matching different heat levels to meet the primary air requirements.

[0203] In some embodiments, the gas cooktop includes a temperature detection element 900.

[0204] The temperature detection element 900 is located inside the pressurization chamber 300 and is configured to detect the temperature of the inner cavity 310.

[0205] In some embodiments, the temperature sensor 900 is electrically connected to the controller, which is configured to control the fan 400 to run when the gas stove stops running and the temperature is greater than a preset value.

[0206] Understandably, when the gas stove stops running, the temperature inside the pressurized chamber 300 can be monitored to quickly cool it down. If the temperature is high, the fan 400 can be activated to cool the burner 200, thereby reducing the overall temperature of the gas stove and improving the user experience.

[0207] In some embodiments, the temperature sensor 900 is located close to the burner 200, which facilitates the temperature sensor 900 in detecting higher temperatures within the pressurization chamber 300, thereby improving the accuracy of the judgment.

[0208] In some embodiments, the controller can control the speed of the fan 400 based on the temperature difference from a preset temperature. This way, when the temperature difference is small, the fan 400 can operate at a lower speed, which helps reduce the noise level during operation.

[0209] In some embodiments, a method for controlling a gas stove is provided.

[0210] Control the start of the gas stove.

[0211] Start the burner 200.

[0212] Control the fan to start at 400.

[0213] Control the thermocouple to detect the thermoelectric potential of burner 200.

[0214] If the thermoelectric potential is less than the first preset value, the valve body and fan 400 of the gas stove are shut off.

[0215] If the thermoelectric potential is not less than the first preset value, the gas stove will continue to operate.

[0216] For example, the first preset value can be 4mV.

[0217] Understandably, thermoelectric potential detection can determine whether the burner 200 has been ignited. If it has not been ignited, the valve body can be closed to effectively prevent gas leakage and improve safety.

[0218] In some embodiments, the control method for a gas stove further includes:

[0219] When the burner 200 stops running, the temperature detection element 900 detects the temperature of the inner cavity 310.

[0220] If the temperature exceeds the preset value, control the fan to run at 400.

[0221] If the temperature exceeds the preset value, control the fan 400 to shut down.

[0222] For example, the preset value can be 60°.

[0223] Understandably, when the gas stove stops running, the temperature inside the pressurized chamber 300 can be monitored to quickly cool it down. If the temperature is high, the fan 400 can be activated to cool the burner 200, thereby reducing the overall temperature of the gas stove and improving the user experience.
