[0054] Gas stoves are commonly used cooking equipment in modern kitchens. They mainly generate flames by burning flammable gases such as petroleum gas, artificial gas, and natural gas to provide heat for cooking activities such as cooking, boiling water, and steaming. With the improvement of living standards, gas stoves have been widely popularized and have become a common kitchen appliance in home life.

[0055] In the related art, a gas stove includes a gas valve, a burner and a bottom shell, and the gas valve and the burner are fixed on the bottom shell, and the bottom shell can provide support and protection for the gas valve and the burner. However, the bottom shell in the related art has poor versatility, and the direct-insertion gas stove and the pipe-type gas stove cannot share the same bottom shell, resulting in a high cost of the gas stove.

[0056] Based on this, see Figure 1 , Figure 1 The present invention provides a gas stove 100 in accordance with an embodiment of the present invention, which is used to solve the problem of poor versatility of the bottom shell of the gas stove in the related art.

[0057] The gas stove 100 may be a tabletop stove, a built-in stove, or a tabletop and built-in dual-purpose stove. The specific selection may be based on actual conditions, and this application does not make any specific limitation on this.

[0058] The gas stove 100 comprises a housing 1 , which is usually placed or installed on a stovetop so that the gas stove 100 can be stably supported, thereby providing a stable support for the cooker.

[0059] See also Figure 2 , Figure 2This is a cross-sectional view of a housing 1 provided in an embodiment of the present application. The housing 1 has an installation cavity 11, which can be used to install some components of the gas stove 100, and the housing 1 can provide support and protection for the components installed in the installation cavity 11. In this way, the risk of damage to the gas stove 100 can be reduced, which is conducive to extending the service life of the gas stove 100.

[0060] For example, Figure 2 As shown, the housing 1 includes a bottom shell 12 and a panel 13. The bottom shell 12 forms a mounting cavity 11 having an opening 121. The panel 13 is disposed on the side of the opening 121 of the bottom shell 12, and the panel 13 covers the opening 121. At this time, the panel 13 and the bottom shell 12 form a closed mounting cavity 11.

[0061] like Figure 3 As shown, Figure 3 The bottom shell 12 is a structural diagram of an embodiment of the present application. The bottom shell 12 may include a bottom plate 122 and a side plate 123. One end of the side plate 123 is connected to the bottom plate 122, and the side plate 123 is arranged around the edge of the bottom plate 122, and together with the bottom plate 122, forms a mounting cavity 11 having an opening 121. In this way, the bottom shell 12 has a simple structure and is easy to implement.

[0062] On this basis, if Figure 3 As shown, the bottom shell 12 may further include a connecting plate 124, which is connected to one end of the side plate 123 away from the bottom plate 122, and the connecting plate 124 is located on the side of the side plate 123 away from the installation cavity 11. The connecting plate 124 is arranged around the side plate 123, and the connecting plate 124 is used to connect with the panel 13 (such as Figure 2 as shown) connection.

[0063] It can be understood that the connecting plate 124 is helpful to increase the contact area between the bottom shell 12 and the panel 13, thereby improving the reliability of the connection between the bottom shell 12 and the panel 13.

[0064] It should be noted that a heat dissipation port 120 may be further provided on the bottom shell 12 , and the heat dissipation port 120 is communicated with the installation cavity 11 . In this way, the heat in the installation cavity 11 may be released through the heat dissipation port 120 .

[0065] The heat dissipation port 120 may be disposed on the bottom plate 122 or on the side plate 123 , and the specific selection may be made according to actual conditions, and this application does not make any specific limitation on this.

[0066] Exemplarily, the heat dissipation vent 120 is disposed on the side plate 123 .

[0067] In some embodiments of the present application, the heat dissipation opening 120 is configured as a shutter structure, so that dust can be reduced from entering the installation cavity 11 through the heat dissipation opening 120 .

[0068] In addition, the number of the heat dissipation ports 120 may be one or more, which may be selected according to actual conditions, and this application does not make any specific limitation on this.

[0069] like Figure 1 As shown, the gas stove 100 further includes a burner 2, which is connected to the housing 1, and the housing 1 can support and fix the burner 2. It can be understood that the burner 2 is usually connected to the gas supply pipeline and is used to burn combustible gas.

[0070] The number of the burners 2 may be one or more, which may be selected according to actual conditions, and this application does not make any specific limitation on this.

[0071] It is understandable that, when there are multiple burners 2, different cookers can be heated simultaneously by different burners 2. This helps to improve cooking efficiency.

[0072] For example, Figure 1 As shown, the number of the burners 2 is two, and the two burners 2 are arranged at an interval.

[0073] In some embodiments, Figure 4 As shown, Figure 4 The panel 13 is provided with a relief hole 131, and the relief hole 131 and the installation cavity 11 (such as Figure 2 As shown) is connected, burner 2 (as shown Figure 1 The avoidance hole 131 may be arranged to extend along the thickness direction of the panel 13.

[0074] It is understandable that, when there are multiple burners 2 , there may also be multiple avoidance holes 131 , and one burner 2 is correspondingly disposed in one avoidance hole 131 .

[0075] See also Figure 1 and Figure 5 , Figure 5 This is a structural diagram of a fastener 3 provided in an embodiment of the present application. In order to fix the burner 2 to the housing 1, the gas stove 100 may further include a fastener 3, one end of the fastener 3 is connected to the burner 2, and the other end is connected to at least one of the bottom shell 12 and the panel 13. In this way, the burner 2 can be fixed to the housing 1 by the fastener 3.

[0076] Exemplarily, the fastener 3 is detachably connected to the burner 2 and the bottom shell 12. Arranged in this way, it is convenient to remove the burner 2 from the bottom shell 12 so as to repair or replace the burner 2.

[0077] It should be noted that the fastener 3 may be a screw, a bolt, a detachable rivet or other parts, which may be selected according to actual conditions, and this application does not make any specific limitation on this.

[0078] In some embodiments, see Figure 6 , Figure 6 A structural diagram of a burner 2 provided in an embodiment of the present application. A connection hole 21 is provided on the burner 2. The connection hole 21 can be either a through hole or a blind hole, which can be selected according to actual conditions, and the present application does not make specific restrictions on this. For example, the connection hole 21 is a blind hole.

[0079] On this basis, see Figure 6 and Figure 7 , Figure 7 The bottom shell 12 is provided with a first fixing hole 125, and the fastener 3 (such as Figure 5 As shown in the figure, the burner 2 can be inserted into the connecting hole 21 and the first fixing hole 125 to fix the burner 2 on the bottom shell 12.

[0080] In this way, see Figure 8 , Figure 8 This is a structural diagram of a bottom shell 12 and a burner 2 provided in an embodiment of the present application. The burner 2 can be fixed in the first position.

[0081] like Fig. 9 As shown, Fig. 9 This is an enlarged view of a bottom shell 12 provided in an embodiment of the present application at a first fixing hole 125 and a second fixing hole 126 .

[0082] In order to make the bottom shell 12 adapt to burners 2 of different sizes, the first fixing hole 125 is configured to include a plurality of first sub-holes 1251 , and the plurality of first sub-holes 1251 included in each first fixing hole 125 are arranged at intervals along the radial direction of the avoidance hole 131 .

[0083] In this way, burners 2 of different sizes can be fixed on the bottom shell 12 through different first sub-holes 1251 to fix the burner 2 at the first position. In this way, the versatility of the bottom shell 12 can be improved.

[0084] It is understandable that the number of the fasteners 3, the connection holes 21 and the first fixing holes 125 can be multiple, and on this basis, one fastener 3 is inserted into one connection hole 21 and one first fixing hole 125. In this way, the burner 2 can be connected to the bottom shell 12 through multiple fasteners 3, which can improve the reliability of the connection between the burner 2 and the bottom shell 12.

[0085] It should be noted that, when there are multiple first fixing holes 125, the multiple first fixing holes 125 are arranged at intervals along the circumference of the avoidance hole 131. For example, there are three first fixing holes 125, and the three fixing holes are evenly arranged along the circumference of the avoidance hole 131.

[0086] Also, see Figure 6 and Figure 7 A second fixing hole 126 may also be provided on the bottom shell 12, and the first fixing hole 125 and the second fixing hole 126 are arranged along the avoidance hole 131 (such as Figure 4 In this case, it is also possible to select the fastener 3 (as shown in FIG. Figure 5 As shown in the figure, the burner 2 is passed through the connecting hole 21 and the second fixing hole 126 to fix the burner 2 on the bottom shell 12.

[0087] In this way, see Fig.10 , Fig.10 This is a structural diagram of a bottom shell 12 and a burner 2 provided in an embodiment of the present application. The burner 2 can be fixed in the second position.

[0088] The second fixing hole 126 may also be configured to include a plurality of second sub-holes 1261 , and the plurality of second sub-holes 1261 included in each second fixing hole 126 are spaced apart along the radial direction of the avoidance hole 131 .

[0089] In this way, burners 2 of different sizes can be fixed on the bottom shell 12 through different second sub-holes 1261 to fix the burner 2 at the second position. In this way, the versatility of the bottom shell 12 can be improved.

[0090] It should be noted that the configuration of the second fixing hole 126 may refer to the configuration of the first fixing hole 125 , and this application will not elaborate on it here.

[0091] See also Fig.11 , Fig.11 The present invention provides a structural diagram of a bottom shell 12, a burner 2 and a gas valve 4. The gas stove 100 provided in the present invention also includes a gas valve 4, which is at least partially located in the installation cavity 11, and the gas supply pipeline can transport combustible gas to the burner 2 through the gas valve 4. In this way, by adjusting the opening of the gas valve 4, the flow rate of the combustible gas can be adjusted, thereby adjusting the firepower of the burner 2.

[0092] It should be noted that when there are multiple burners 2 , there can also be multiple gas valves 4 , one gas valve 4 corresponds to one burner 2 , and the gas supply pipeline can transport combustible gas to the corresponding burner 2 through the gas valve 4 .

[0093] It can be understood that the burner 2 has an air inlet 22 and an air outlet, and the combustible gas can enter the burner 2 through the air inlet 22 and flow out through the air outlet, and then be ignited at the air outlet to heat the cooker.

[0094] In some embodiments, see Figure 6 The burner 2 includes a burner head 23 and an ejector tube 24 which are connected to each other. The burner head 23 is inserted into the avoidance hole 131 , and the ejector tube 24 is located in the installation cavity 11 .

[0095] Among them, Fig.11 As shown, the burner head 23 has a gas mixing chamber 231 , the ejector pipe 24 is in communication with the gas mixing chamber 231 , and the ejector pipe 24 is used to eject air and combustible gas into the gas mixing chamber 231 .

[0096] Exemplarily, the gas mixing chamber 231 may include a first sub-chamber 2311 and a second sub-chamber 2312 that are independent of each other, and the first sub-chamber 2311 is arranged around the second sub-chamber 2312 .

[0097] On this basis, the ejector tube 24 includes a main ejector tube 241 and a secondary ejector tube 242 . The main ejector tube 241 is connected to the first sub-cavity 2311 , and the secondary ejector tube 242 is connected to the second sub-cavity 2312 .

[0098] Arranged in this way, the main ejector tube 241 can eject air and combustible gas into the first sub-chamber 2311 , and the secondary ejector tube 242 can eject air and combustible gas into the second sub-chamber 2312 .

[0099] Understandably, see Figure 6 The connection hole 21 can be set on the furnace head 23 or on the ejector tube 24. The specific selection can be made according to actual conditions, and this application does not make any specific limitation on this.

[0100] The following takes the example of the connection hole 21 being arranged on the furnace head 23 to exemplarily illustrate some embodiments of the present application.

[0101] In some embodiments, see Figure 7 The bottom shell 12 is further provided with a first mounting hole 130 and a second mounting hole 140 , and the first mounting hole 130 and the second mounting hole 140 are spaced apart along the circumferential direction of the avoidance hole 131 .

[0102] See also Figure 6 The burner 2 further includes a mounting plate 25, which is located in the mounting cavity 11 (eg Figure 3 As shown in the figure, the mounting plate 25 is connected to the ejector tube 24, and a third mounting hole 251 is provided on the mounting plate 25.

[0103] On this basis, the gas stove 100 further includes a mounting part, wherein the mounting part may be a screw, a bolt, a detachable rivet or other parts, which may be selected according to actual conditions, and the present application does not make any specific limitation on this.

[0104] It should be noted that, when the burner 2 is fixed to the first position, the mounting member can be inserted into the first mounting hole 130 and the third mounting hole 251, and can be detachably connected to the mounting plate 25 and the bottom shell 12. When the burner 2 is fixed to the second position, the mounting member can be inserted into the second mounting hole 140 and the third mounting hole 251, and can be detachably connected to the mounting plate 25 and the bottom shell 12.

[0105] In this way, the burner 2 can be fixed to the bottom shell 12 by the mounting member, so as to improve the reliability of the connection between the burner 2 and the bottom shell 12 .

[0106] Among them, see Fig. 9 The first mounting hole 130 may be configured to include a plurality of first sub-mounting holes 1301. When the burner 2 is fixed at the first position, the plurality of first sub-mounting holes 1301 are arranged along the ejector tube 24 (eg Figure 6 In this way, burners 2 of different sizes can be fixed on the bottom shell 12 through different first sub-mounting holes 1301 to improve the versatility of the bottom shell 12.

[0107] Similarly, the second mounting hole 140 may be configured to include a plurality of second sub-mounting holes 1401. When the burner 2 is fixed at the second position, the plurality of second sub-mounting holes 1401 are spaced apart along the extending direction of the ejector tube 24. In this way, burners 2 of different sizes can be fixed to the bottom shell 12 through different second sub-mounting holes 1401, so as to improve the versatility of the bottom shell 12.

[0108] It should be noted that the burner 2 can be divided into a left-handed burner and a right-handed burner according to the different airflow rotation directions. In the left-handed burner and the right-handed burner, there is a difference in the relative position of the ejector tube 24 and the burner head 23, resulting in a difference in the relative position of the mounting plate 25 connected to the ejector tube 24 and the burner head 23. As a result, the position of the third mounting hole 251 in the left-handed burner is different from the position of the third mounting hole 251 in the right-handed burner.

[0109] In order to make the bottom shell 12 adapt to both left-handed burners and right-handed burners, Figure 7 As shown, the first mounting hole 130 can be configured to include a first left hole 1302 and a first right hole 1303. When the burner 2 is in the first position, the left-rotating burner can be mounted on the bottom shell 12 through the first left hole 1302, and the right-rotating burner can be mounted on the bottom shell 12 through the first right hole 1303.

[0110] Similarly, the second mounting hole 140 can be configured to include a second left hole 1402 and a second right hole 1403. When the burner 2 is in the second position, the left-rotating burner can be mounted on the bottom shell 12 through the second left hole 1402, and the right-rotating burner can be mounted on the bottom shell 12 through the second right hole 1403.

[0111] In some embodiments, Fig.11 As shown, the direction of the air inlet 22 of the burner 2 is aligned with the avoidance hole 131 (as shown in FIG. Figure 4 And, when the burner 2 is fixed to the first position, the air inlet 22 faces the gas valve 4.

[0112] In addition, if Fig.12 As shown, Fig.12 The present invention provides a structural diagram of a bottom shell 12, a burner 2, a gas valve 4, a connecting pipe 8 and a second air inlet pipe 9. When the burner 2 is fixed to the second position, the air inlet 22 faces one side of the gas valve 4.

[0113] In this way, on the one hand, the fastener 3 can be selected to be inserted into the connection hole 21 and the first fixing hole 125, so that the fastener 3 is connected to the burner 2 and the bottom shell 12, thereby fixing the burner 2 to the first position, so that the air inlet 22 of the burner 2 faces the gas valve 4. In this way, it is convenient for the main structure of the gas valve 4 to be directly inserted into the air inlet 22 of the burner 2, so as to achieve the installation of the direct plug-in platform structure of the gas stove 100. On the other hand, the fastener 3 can be selected to be inserted into the connection hole 21 and the second fixing hole 126, so that the fastener 3 is connected to the burner 2 and the bottom shell 12, thereby fixing the burner 2 to the second position, so that the direction of the air inlet 22 of the burner 2 deviates from the gas valve 4. In this way, it is convenient for the main structure of the gas valve 4 to be connected to the air inlet 22 of the burner 2 through a pipeline, so as to achieve the installation of the pipe-type platform structure of the gas stove 100.

[0114] Based on this, the bottom shell 12 in the present application can be applicable to both the plug-in gas stove 100 and the pipe-type gas stove 100. The bottom shell 12 has high versatility and there is no need to develop different bottom shell 12 molds for the plug-in gas stove 100 and the pipe-type gas stove 100. This can save the cost of a set of bottom shell 12 molds, which is beneficial to reducing the cost of the gas stove 100.

[0115] In some embodiments, Figure 7 As shown, the distances between the first fixing hole 125 and the second fixing hole 126 and the axis of the avoidance hole 131 are equal.

[0116] It is understandable that the portion of the burner 2 that passes through the avoidance hole 131 is usually coaxially arranged with the avoidance hole 131. Based on this, the distance between the axes of the first fixing hole 125 and the avoidance hole 131 is set to be equal to the distance between the axes of the second fixing hole 126 and the avoidance hole 131. The burner 2 only needs to be rotated around the axis of the avoidance hole 131 until the connecting hole 21 is aligned with the first fixing hole 125 or the second fixing hole 126, and the burner 2 can be conveniently fixed to the first position or the second position by the fastener 3.

[0117] Arranging in this way facilitates adjustment of the fixed position of the burner 2 and enables the portion of the burner 2 that passes through the avoidance hole 131 to remain coaxial with the avoidance hole 131 .

[0118] In some embodiments, see Fig.12 The bottom shell 12 is also provided with a gas supply port 127, and the gas supply port 127 is connected to the installation cavity 11 (such as Fig.11 shown) connected.

[0119] In this way, air can enter the installation cavity 11 through the air supply port 127, and then enter the burner 2 through the air inlet 22. After being evenly mixed with the combustible gas entering the burner 2, air flows out through the air outlet and is finally ignited at the air outlet to heat the cooker.

[0120] It should be noted that if Fig.13 As shown, Fig.13 The structure diagram of a burner 2, an air flap 5, a gas valve 4 and a nozzle 6 provided in an embodiment of the present application. The gas stove 100 may further include an air flap 5, which is connected to the burner 2 and blocks part of the air inlet 22.

[0121] The air flap 5 can be moved relative to the burner 2 to adjust the area of ​​the air inlet 22 blocked by the air flap 5. For example, the air flap 5 is rotatably connected to the burner 2, and the area of ​​the air inlet 22 blocked by the air flap 5 can be adjusted by rotating the air flap 5.

[0122] In this case, the air flow rate entering the burner 2 can be adjusted by adjusting the air flap 5. In this way, the air flow rate entering the burner 2 can be matched with the combustible gas flow rate, and the risk of flameout and black smoke in the gas stove 100 can be reduced.

[0123] In order to facilitate the adjustment of the air flap 5 , the air flap 5 may be inserted into the air supply port 127 .

[0124] For example, Fig.12As shown, the air supply port 127 includes a first air port 1271 and a second air port 1272 , and both the first air port 1271 and the second air port 1272 are connected to the installation cavity 11 .

[0125] When the burner 2 is fixed to the first position, the air flap 5 is inserted into the first air port 1271 ; when the burner 2 is fixed to the second position, the air flap 5 is inserted into the second air port 1272 .

[0126] It is understandable that the first air outlet 1271 and the second air outlet 1272 can be independently provided or connected to each other, which can be selected according to actual conditions, and the present application does not make any specific limitation on this.

[0127] For example, Fig.12 As shown, the first air inlet 1271 and the second air inlet 1272 are connected to each other. In this way, it is convenient to use the same production process to make the first air inlet 1271 and the second air inlet 1272 on the bottom shell 12 at the same time, which is conducive to improving the production efficiency of the bottom shell 12.

[0128] It should be noted that the present application does not specifically limit the shapes of the first air outlet 1271 and the second air outlet 1272, which can be selected according to actual conditions. For example, the first air outlet 1271 and the second air outlet 1272 can both be configured as strips.

[0129] Some embodiments of the present application are schematically described below by taking the first air outlet 1271 and the second air outlet 1272 being in strip shape as an example.

[0130] In some embodiments, see Figure 8 When the burner 2 is fixed to the first position, the extension direction of the first air port 1271 is aligned with the air inlet 22 (eg Fig.11 ) is oriented vertically.

[0131] See also Fig.10 When the burner 2 is fixed to the second position, the extension direction of the second air port 1272 is aligned with the air inlet 22 (eg Fig.11 ) is oriented vertically.

[0132] Among them, see Figure 7 , the angle between the extension direction of the first air outlet 1271 and the extension direction of the second air outlet 1272 can be set to be greater than or equal to 40°. For example, the angle α between the extension direction of the first air outlet 1271 and the extension direction of the second air outlet 1272 can be set to any one of 40°, 45°, 50°, 55° and 60°. The specific selection can be made according to the actual situation, and this application does not make specific limitations on this.

[0133] By configuring in this manner, the distances between the burner 2 and the first air port 1271 and the second air port 1272 can be shortened, so that the structure of the gas stove 100 can be more compact, which is beneficial to reducing the space occupied by the gas stove 100 .

[0134] In addition, the angle α between the extension direction of the first air outlet 1271 and the extension direction of the second air outlet 1272 can also be set to be less than or equal to 50°. For example, the angle between the extension direction of the first air outlet 1271 and the extension direction of the second air outlet 1272 can be set to any one of 50°, 45°, 40°, 35° and 30°. The specific selection can be made according to the actual situation, and this application does not make specific limitations on this.

[0135] Arranged in this way, it is possible to avoid the difficulty of assembling the gas stove 100 due to the small distance between the burner 2 and the first air port 1271 and the second air port 1272, which is beneficial to reducing the difficulty of assembling the gas stove 100 and improving the assembly efficiency of the gas stove 100.

[0136] See also Fig.14 , Fig.14 The gas stove 100 provided in the embodiment of the present application may also include a nozzle 6, wherein the nozzle 6 is located at the air inlet 22 (such as Fig.10 As shown), it is used to inject the combustible gas into the burner 2 through the air inlet 22.

[0137] It is understandable that, when the combustible gas is sprayed into the burner 2 through the nozzle 6 , it can drive the air around the air inlet 22 to enter the burner 2 through the air inlet 22 , so that the combustible gas is mixed with the air.

[0138] In some embodiments, see Fig.15 , Fig.15 A structural diagram of a bottom shell 12, a burner 2, a gas valve 4 and a first air inlet pipe 7 provided in an embodiment of the present application. The burner 2 is fixed in a first position. The gas valve 4 includes a valve body 41 and an injection pipe 42. The valve body 41 is provided with an inlet and an outlet, and the inlet is used to communicate with the gas supply pipeline. One end of the injection pipe 42 is connected to the outlet, and the other end is connected to the nozzle 6.

[0139] The valve body 41 and the injection pipe 42 may be integrally formed.

[0140] In this way, the main structure of the gas valve 4 can be directly connected to the nozzle 6, and then the combustible gas is sprayed into the burner 2 through the nozzle 6. In this way, the bottom shell 12 can realize the installation of the direct plug-in platform structure of the gas stove 100.

[0141] It should be noted that see Fig.10 The bottom shell 12 may also be provided with a mounting opening 128, and the mounting opening 128 is connected to the mounting cavity 11 (such as Fig.11 shown) connected.

[0142] On this basis, see Fig.16 , Fig.16 The structure diagram of a first air inlet pipe 7 provided in an embodiment of the present application is shown in FIG. The gas stove 100 further includes a first air inlet pipe 7 , which is passed through the installation opening 128 and communicated with the inlet of the valve body 41 .

[0143] The first air inlet pipe 7 is also used to communicate with the air supply pipeline. In this way, the air supply pipeline can supply gas to the gas valve 4 through the first air inlet pipe 7, and then the combustible gas is transported to the nozzle 6 through the gas valve 4 and sprayed into the burner 2 through the nozzle 6.

[0144] For example, Fig.16 As shown, the first air inlet pipe 7 includes a first main pipe 71 and a first branch pipe 72. The first main pipe 71 is arranged through the installation opening 128 (such as Fig.10 ) and away from the mounting cavity 11 (as shown Fig.11 One end of the first branch pipe 72 is used to connect the air supply pipeline. The first branch pipe 72 is arranged in the installation cavity 11 and is connected to the first main pipe 71 and the inlet.

[0145] The extending direction of the first branch pipe 72 is perpendicular to the direction of the air inlet 22 .

[0146] By arranging in this way, after the valve body 41 is installed on the first branch pipe 72 , it is convenient to connect the injection pipe 42 to the nozzle 6 at the air inlet 22 , which helps to reduce the difficulty of installing the gas valve 4 .

[0147] On this basis, see Fig.15 If the number of the burners 2 and the number of the gas valves 4 are both two, the two gas valves 4 can be arranged between the two burners 2. At this time, the extension direction of the first main pipe 71 can be arranged to be perpendicular to the arrangement direction of the two burners 2, and one end of the first branch pipe 72 is connected to the first main pipe 71, and the other end is arranged to be inclined toward the direction close to the burner 2.

[0148] In this case, if Fig.16 As shown, the first air inlet pipe 7 can be configured as a Y-shaped pipe.

[0149] For example, the first air inlet pipe 7 is provided with a first fastening hole 73, and the bottom shell 12 is provided with a second fastening hole 150 (such as Fig.10 shown).

[0150] On this basis, the gas stove 100 further includes a connecting piece, which is inserted into the first fastening hole 73 and the second fastening hole 150 and is detachably connected to the first air inlet pipe 7 and the bottom shell 12 .

[0151] Among them, the connecting parts can be screws, bolts, detachable rivets and other parts, which can be selected according to actual conditions, and this application does not make specific limitations on this.

[0152] It is understandable that the number of the first fastening hole 73, the second fastening hole 150 and the connecting piece can be one or more, which can be selected according to actual conditions, and the present application does not make any specific limitation on this.

[0153] It should be noted that, when there are multiple first fastening holes 73, second fastening holes 150, and connectors, one connector is inserted into one first fastening hole 73 and one second fastening hole 150, and is detachably connected to the first air intake pipe 7 and the bottom shell 12. In this way, the first air intake pipe 7 can be connected to the bottom shell 12 through multiple connectors at the same time, which can improve the reliability of the connection between the first air intake pipe 7 and the bottom shell 12.

[0154] In some embodiments, see Fig.16 The first air inlet pipe 7 further includes a leg 74, which is located between the first branch pipe 72 and the bottom shell 12, the leg 74 contacts the bottom shell 12, and the leg 74 is connected to the first branch pipe 72, so that the leg 74 can provide stable support for the first branch pipe 72. At this time, the leg 74 can be provided with a first fastening hole 73.

[0155] In addition, the first air inlet pipe 7 may further include an ear plate 75, which is located on a side of the first main pipe 71 close to the burner 2 and connected to the first main pipe 71. At this time, the ear plate 75 may also be provided with a first fastening hole 73.

[0156] In other embodiments, Fig.12 As shown, the burner 2 is fixed in the second position. The gas valve 4 has an inlet end and an outlet end, and the inlet end is used to communicate with the gas supply pipeline.

[0157] On this basis, the gas stove 100 further includes a connecting pipe 8 , one end of which is connected to the outlet end, and the other end of which is connected to the nozzle 6 .

[0158] In this way, the main structure of the gas valve 4 can be connected to the nozzle 6 through the pipeline, and then the combustible gas is sprayed into the burner 2 through the nozzle 6. In this way, the bottom shell 12 can realize the installation of the pipe-type platform structure of the gas stove 100.

[0159] It should be noted that see Fig.10The bottom shell 12 is also provided with a mounting opening 128, and the mounting opening 128 is connected to the mounting cavity 11 (such as Fig.11 shown) connected.

[0160] On this basis, if Fig.17 As shown, Fig.17 The structure diagram of a second air inlet pipe 9 provided in an embodiment of the present application. The gas stove 100 further includes a second air inlet pipe 9 , which is passed through the installation opening 128 and communicated with the inlet end of the gas valve 4 .

[0161] The second air inlet pipe 9 is also used to communicate with the air supply pipeline. In this way, the air supply pipeline can supply gas to the gas valve 4 through the second air inlet pipe 9, and then the combustible gas is transported to the nozzle 6 through the gas valve 4 and the connecting pipe 8, and then sprayed into the burner 2 through the nozzle 6.

[0162] For example, Fig.17 As shown, the second air inlet pipe 9 includes a second main pipe 91 and a second branch pipe 92. The second main pipe 91 is arranged through the installation opening 128 (such as Fig.10 ) and away from the mounting cavity 11 (as shown Fig.11 The second branch pipe 92 is arranged in the installation cavity 11 and is connected with the second main pipe 91 and the inlet end.

[0163] The extending direction of the second branch pipe 92 is parallel to the direction of the air inlet 22 .

[0164] Arranged in this way, after the gas valve 4 is installed on the second branch pipe 92 , it is convenient to connect the connecting pipe 8 to the outlet end of the gas valve 4 and the nozzle 6 , which helps to reduce the difficulty of installing the gas valve 4 .

[0165] In certain embodiments of the present application, a fixing hole is provided on the gas valve 4 , and a semicircular clamp is provided on the second air intake pipe 9 , so as to connect the gas valve 4 and the second air intake pipe 9 .

[0166] In certain embodiments of the present application, Figure 8 The two gas valves 4 shown are fixed to the bottom shell 12 through valve fixing holes A1 and A2 respectively, so as to improve the reliability of the installation of the gas valve 4. There are two valve fixing holes A1 on the same side, and two valve fixing holes A2 on the other side.

[0167] On this basis, see Fig.15 If the number of the burners 2 and the number of the gas valves 4 are both two, the two gas valves 4 can be arranged between the two burners 2. At this time, the extension direction of the second main pipe 91 can be set to be perpendicular to the arrangement direction of the two burners 2, and the extension direction of the second branch pipe 92 can be set to be parallel to the arrangement direction of the two burners 2.

[0168] In this case, if Fig.17 As shown, the second air inlet pipe 9 can be configured as a T-shaped pipe.

[0169] In some embodiments, see Fig.10 , a third fastening hole 160 is defined on the bottom shell 12 .

[0170] See also Fig.18 , Fig.18 The present invention provides a structural diagram of a bottom shell 12, a second air inlet pipe 9 and a stopper 10. The gas stove 100 further includes a stopper 10 and a fixing member, the stopper 10 is connected to the second air inlet pipe 9, and a fourth fastening hole 101 is provided on the stopper 10, the fixing member is inserted into the third fastening hole 160 and the fourth fastening hole 101, and the fixing member is detachably connected to the stopper 10 and the bottom shell 12.

[0171] Among them, the fixing parts can be screws, bolts, detachable rivets and other parts, which can be selected according to actual conditions, and this application does not make specific limitations on this.

[0172] It is understandable that the number of the third fastening hole 160, the limiting member 10 and the fixing member can be one or more, which can be selected according to actual conditions, and the present application does not make any specific limitation on this.

[0173] It should be noted that, when there are multiple third fastening holes 160, multiple stoppers 10, and multiple fixings, one fixing is inserted into one third fastening hole 160 and one fourth fastening hole 101 of the stopper 10, and is detachably connected to the stopper 10 and the bottom shell 12. In this way, the second air intake pipe 9 can be connected to the bottom shell 12 through multiple stoppers 10 and multiple fixings at the same time, which can improve the reliability of the connection between the second air intake pipe 9 and the bottom shell 12.

[0174] In some embodiments, see Figure 3 A plurality of concave and convex pressed structures 129 are provided on the bottom shell 12 .

[0175] On this basis, see Fig.14 , the burner 2, the combustion valve and other components can be arranged on different press-type structures 129. Among them, the press-type structure 129 can be used to balance the installation height of the burner 2, the combustion valve and other components, which is conducive to reducing the difficulty of assembling the gas stove 100.

[0176] In some embodiments, see Fig.19 , Fig.19 The top view of a gas stove 100 provided in an embodiment of the present application is shown with the panel 13 removed. The gas stove 100 further includes a battery box 20 and a pulse igniter 30, and the battery box 20 and the pulse igniter 30 are electrically connected.

[0177] The battery box 20 may be used to install batteries, thereby supplying power to the pulse igniter 30 so that the pulse igniter 30 generates electric sparks for igniting the combustible gas.

[0178] On this basis, see Fig. 20 , Fig. 20 The bottom shell 12 is a top view of the embodiment of the present application. The bottom shell 12 is also provided with an escape opening 170, and the battery box 20 is inserted into the escape opening 170. This arrangement facilitates the replacement of the battery in the battery box 20.

[0179] In some embodiments, see Fig.19 The gas stove 100 includes two gas valves 4 and two burners 2 arranged at intervals.

[0180] Along the arrangement direction of the two burners 2, the two gas valves 4 are located between the two burners 2. Along the first direction X, the two gas valves 4 are located on the same side of the two burners 2. The first direction X is perpendicular to the arrangement direction of the two burners 2, and the first direction X is perpendicular to the axis of the avoidance hole 131.

[0181] On this basis, see Fig. 20 The avoidance opening 170 may be configured to include a first sub-opening 1701 and a second sub-opening 1702. When the burner 2 is fixed at the first position, the battery box 20 is inserted into the first sub-opening 1701; when the burner 2 is fixed at the second position, the battery box 20 is inserted into the second sub-opening 1702.

[0182] In which, along the arrangement direction of the two burners 2, the first sub-port 1701 is located between the two burners 2; along the first direction X, the first sub-port 1701 and the two burners 2 are located on the same side of the two gas valves 4. Along the arrangement direction of the two burners 2, the second sub-port 1702 is located on the side of the two gas valves 4 close to one of the burners 2; along the first direction X, the second sub-port 1702 and the two gas valves 4 are located on the same side of the two burners 2.

[0183] Arranged in this way, it is possible to avoid interference of the battery box 20 with the installation of the burner 2 or the gas valve 4, so that the bottom shell 12 can be adapted to the direct plug-in platform structure and the pipe-type platform structure.

[0184] It should be noted that see Fig.18 The gas stove 100 may further include a cover plate 40 , and the cover plate 40 is detachably connected to the bottom shell 12 .

[0185] When the battery box 20 is inserted into the first sub-opening 1701, the cover plate 40 is covered on the second sub-opening 1702; when the battery box 20 is inserted into the second sub-opening 1702, the cover plate 40 is covered on the first sub-opening 1701. It can be understood that the cover plate 40 can prevent particles, dust, etc. in the air from entering the installation cavity 11.

[0186] Exemplarily, the pulse igniter 30 is detachably connected to the bottom shell 12. For example, the pulse igniter 30 can be connected to the bottom shell 12 by screw connection, bolt connection, clamping, etc.

[0187] On this basis, see Fig. 20 A first fixed position 180 and a second fixed position 190 are provided on the bottom shell 12. When the burner 2 is fixed at the first position, the pulse igniter 30 is fixed at the first fixed position 180; when the burner 2 is fixed at the second position, the pulse igniter 30 is fixed at the second fixed position 190.

[0188] In which, along the arrangement direction of the two burners 2, the first fixed position 180 is located between the two burners 2; along the first direction X, the first fixed position 180 and the first sub-port 1701 are located on the same side of the two gas valves 4.
