[0047] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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 1Schematic diagram of a gas stove provided in the present application. The gas stove 100 includes a bottom shell 11, a burner 12 and a panel 13. The bottom shell 11 forms an installation cavity 10 with an opening, and the bottom shell 11 is mainly used to install relevant components of the gas stove 100, such as the burner 12, the gas control system and the electronic ignition system. These components can be installed in the installation cavity 10 of the bottom shell 11, and the panel 13 is covered on the opening of the bottom shell 11 to cover the installation cavity 10 of the bottom shell 11. In this way, the panel 13 can protect the components arranged in the installation cavity 10.

[0052] On this basis, the panel 13 is further provided with an avoidance hole 130, and the burner 12 is arranged opposite to the avoidance hole 130 on the panel 13, so that the burner 12 can be located within the opening range of the avoidance hole 130. In this way, when the burner 12 burns the mixed gas to generate flames, the panel 13 will not affect the normal operation of the burner 12.

[0053] Continue to refer to Figure 1 In addition to the above main components, the gas stove 100 also includes some indispensable components for realizing the gas stove 100. These components include a valve body 14, a knob 15, an ignition needle 16 and a thermocouple 17 (see Figure 2 ). The valve body 14 can control the on-off and flow rate of the gas. The valve body 14 is used to control the on-off of the gas in the burner 12 or to increase or decrease the flow rate of the gas. The knob 15 is connected to the valve body 14, so that the user can control the ignition and the size of the flame through the knob 15. When the knob 15 is turned, the ignition needle 16 will ignite the gas, and the gas will burn to form a flame. When the gas stove 100 is turned off, the thermocouple 17 will sense the flameout, so that the valve body 14 can be closed through relevant operations to stop the delivery of gas.

[0054] Continue to refer to Figure 1 The gas stove 100 may further include some parts to improve the gas stove 100. A knob mounting hole 150 is provided on the panel 13, and the knob 15 is installed in the knob mounting hole 150. In this case, in order to prevent the liquid accidentally overflowing from the pot from flowing into the mounting cavity 10 of the bottom shell 11 from the knob mounting hole 150, the gas stove 100 may further include a knob waterproof ring 151, which is arranged at the knob mounting hole 150 to prevent the overflowing liquid from flowing into the inside of the bottom shell 11 from the knob mounting hole 150. Similarly, the overflowing liquid may also flow into the inside of the bottom shell 11 from the avoidance hole 130 on the panel 13. Therefore, a liquid receiving tray 131 is provided at the avoidance hole 130, and the overflowing liquid can flow into the liquid receiving tray 131.

[0055] Among the above-mentioned components, the burner 12 is the core component of the gas stove 100. The burner 12 can mix the gas and the primary air in a certain way, and the mixed gas obtained by mixing the gas and the primary air can flow out of the burner and be ignited to form a flame.

[0056] Next, the burner 12 of the gas stove 100 provided by the present application will be further described in conjunction with the accompanying drawings. Figure 2 As shown, the burner 12 may include a burner head 121, and the burner head 121 is formed with an open gas mixing chamber 1210. The primary air and the gas are mixed in the gas mixing chamber 1210 of the burner head 121 to form a mixed gas of the primary air and the gas for combustion.

[0057] Another example Figure 2 As shown, the burner head 121 comprises a burner head seat 1211 and a burner head cover 1212. The burner head seat 1211 is formed with the gas mixing chamber 1210, and the primary air and the gas are mixed in the gas mixing chamber 1210 of the burner head seat 1211.

[0058] The furnace head cover 1212 is disposed on the opening of the furnace head seat 1211. Figure 2 An air outlet 12120 is provided on the burner cover 1212 , and the air outlet 12120 is communicated with the gas mixing chamber 1210 of the burner seat 1211 , so that the primary air and gas mixed in the gas mixing chamber 1210 can continue to flow out through the air outlet 12120 provided on the burner cover 1212 .

[0059] On this basis, if Figure 3 As shown, the gas stove 100 provided in the present application further includes a fire cover seat 21, and the fire cover seat 21 is covered on the burner head 121. Figure 3 The fire cover seat 21 is formed with a uniform gas chamber 210, and the uniform gas chamber 210 and the mixing gas chamber 1210 (see Figure 2 ) are connected.

[0060] In addition, see Figure 3 The fire cover seat 21 is annular, the ignition needle 16 and the thermocouple 17 pass through the inner ring of the fire cover seat 21, and the ignition needle 16 and the thermocouple 17 are both connected to the furnace head cover 1212, that is, the ignition needle 16 and the thermocouple 17 are connected to the furnace head 121 through the furnace head cover 1212.

[0061] like Figure 4 As shown, an air inlet 2100 is provided on the surface of the fire cover seat 21 close to the burner head 121. Figure 5 As shown, the air inlet 2100 is communicated with the air outlet 12120 opened on the furnace head cover 1212 , so that the gas homogenizing chamber 210 can be communicated with the gas mixing chamber 1210 .

[0062] On this basis, if Figure 2 As shown, the gas stove 100 provided in the present application further includes a fire cover 22, and the fire cover 22 and the fire cover seat 21 constitute a fire cover assembly 2. The fire cover 22 is disposed on the fire cover seat 21 and communicates with the uniform air cavity 210 of the fire cover seat 21. Figure 3 As shown, a plurality of fire holes 220 are provided on the fire cover 22 , and the fire holes 220 are connected to the gas uniforming cavity 210 .

[0063] See also Figure 2-Figure 3 In this way, the mixed gas mixed in the mixing chamber 1210 enters the uniform gas chamber 210 of the fire cover seat 21 through the connected outlet 12120 and the inlet 2100, and the mixed gas is evenly distributed in the uniform gas chamber 210, and then flows out from the fire hole 220 of the fire cover 22 and is ignited to form a flame.

[0064] However, during daily use of the gas stove 100 , it is inevitable that food residues fall on the fire cover 22 , or soup overflows from the pot, which may cause the fire hole 220 to be blocked, affecting the normal use of the gas stove 100 .

[0065] Based on this, it may be necessary to remove the fire cover 22 and the fire cover seat 21 from the burner 121 for cleaning or maintenance. After cleaning or maintenance, when the fire cover seat 21 and the fire cover 22 are put back on the burner 121, the user cannot directly see the air inlet 2100 on the fire cover seat 21 and the air outlet 12120 on the burner cover 1212, so it is easy for the fire cover seat 21 to not be correctly placed on the burner cover 1212. This may cause the gas stove 100 to fail to burn normally or even cause a risk of gas leakage, greatly affecting the cooking safety of the user.

[0066] In order to prevent the fire cover seat 21 from being properly placed on the stove head cover 1212, Figure 6 As shown, the gas stove 100 provided in the present application further includes a foolproof component 3, which is connected to the fire cover seat 21 and is located at the inner ring of the fire cover seat 21. The foolproof component 3 and the ignition needle 16 and the thermocouple 17 are staggered along the circumference of the fire cover seat 21. The foolproof component 3 is used to abut against the ignition needle 16 and the thermocouple 17 when the fire cover seat 21 is installed on the burner 121, so as to prevent the fire cover seat 21 from being installed misplaced, thereby avoiding the risk of the gas stove 100 failing to burn normally or even leaking.

[0067] In this way, when the user is installing the fire cover seat 21, the installation can be completed only when the foolproof component 3 does not abut against the ignition needle 16 or the thermocouple 17. Figure 7 , along Figure 7In the process of placing the fire cover seat 21 on the burner head 121 in the Z direction, if the fool-proofing component 3 is located above the ignition needle 16 or the thermocouple 17, then in the process of moving the fire cover seat 21 along the Z direction, the fool-proofing component 3 will interfere with at least one of the ignition needle 16 or the thermocouple 17, so that the fire cover seat 21 cannot continue to move along the Z direction, and then the fire cover seat 21 cannot be placed on the burner head 121, which serves to remind the user that the fire cover seat 21 is not installed properly.

[0068] Another example Figure 8 As shown, Figure 8 For the correct installation of the fire cover seat 21, the foolproof component 3 connected to the fire cover seat 21 is staggered with the ignition needle 16 and the thermocouple 17 along the circumference of the fire cover seat 21, that is, the foolproof component 3 is not located above the ignition needle 16 and the thermocouple 17. Figure 8 The fire cover seat 21 can be correctly placed on the burner head 121 by moving in the Z direction.

[0069] It is understandable that when the gas stove 100 burns gas to provide flame, the primary air initially mixed with the gas can provide the air required for combustion. On this basis, the gas stove 100 also needs to supplement secondary air to burn gas to ensure sufficient combustion of the gas.

[0070] In this case, in order to ensure that the foolproof component 3 arranged on the inner ring of the fire cover seat 21 does not affect the replenishment of secondary air, Fig. 9 As shown, in some embodiments of the present application, a first vent 30 is provided on the fool-proof component 3 , and the first vent 30 runs through the fool-proof component 3 .

[0071] In this way, when the secondary air enters the inner ring of the fire cover seat 21 through the gap between the fire cover seat 21 and the burner head 121, the secondary air can enter the inner ring of the fire cover seat 21 through the first vent 30 provided on the foolproof component 3, providing secondary air for the inner ring flame and the outer ring flame. In this way, the secondary air can be sufficient while playing the foolproof role, thereby ensuring that the gas can be fully burned.

[0072] It should be noted that the diameter of the first vent 30 should not be too large. The diameter of the first vent 30 should be smaller than the diameters of the ignition needle 16 and the thermocouple 17 to prevent the ignition needle 16 or the thermocouple 17 from passing through the first vent 30, causing the foolproof component 3 to lose its foolproof function.

[0073] As can be seen from the above, the anti-mistake assembly 3 can prevent the fire cover seat 21 from being misplaced during installation. Next, the anti-mistake assembly 3 will be further described in conjunction with the accompanying drawings. Fig. 9As shown, the foolproof assembly 3 includes at least one foolproof baffle 31 , and the foolproof baffle 31 is arranged at intervals along the circumference of the inner ring of the fire cover seat 21 .

[0074] Based on this, at least one foolproof baffle 31 is used to abut against the ignition needle 16 when the fire cover seat 21 is installed on the burner 121 to prevent the fire cover seat 21 from being installed in a wrong position. Alternatively, at least one foolproof baffle 31 is used to abut against the thermocouple 17 when the fire cover seat 21 is installed on the burner 121 to prevent the fire cover seat 21 from being installed in a wrong position. Alternatively, at least one foolproof baffle 31 is used to abut against the ignition needle 16 and the thermocouple 17 when the fire cover seat 21 is installed on the burner 121 to prevent the fire cover seat 21 from being installed in a wrong position.

[0075] On this basis, if Fig. 9 As shown, the foolproof baffle 31 is provided with a first vent 30 , and the first vent 30 penetrates the foolproof baffle 31 . The diameter of the first vent 30 is smaller than the diameter of the ignition needle 16 and the thermocouple 17 .

[0076] In this way, when the foolproof baffle 31 abuts against the ignition needle 16 or the thermocouple 17 to play a foolproof role, the first vent 30 opened on the foolproof baffle 31 can ensure that the foolproof baffle 31 does not affect the replenishment of secondary air. The obstruction of the secondary air in the process of entering the inner ring of the fire cover seat 21 from between the burner head cover 1212 and the fire cover seat 21 is reduced, and the secondary air is sufficient to ensure that the mixed gas burns fully.

[0077] In other embodiments, Fig.10 As shown, in the case where the first vent 30 is provided on the foolproof baffle plate 31, the foolproof baffle plate 31 further includes a stopper rod 300, which is arranged in the first vent 30, connected to the inner side wall of the first vent 30, and the straight line where the stopper rod 300 is located in the length direction passes through the center of the first vent 30. In this way, the possibility of the ignition needle 16 or the thermocouple 17 passing through the first vent 30 can be further reduced, so that when the fire cover seat 21 is misplaced while ensuring sufficient secondary air, the foolproof baffle plate 31 can abut against the ignition needle 16 or the thermocouple 17 to play a foolproof role.

[0078] In some other embodiments of the present application, there are multiple anti-foolproof baffles 31 , and the multiple anti-foolproof baffles 31 are arranged at intervals along the circumference of the inner ring of the fire cover seat 21 .

[0079] For example, Fig.11As shown, the number of foolproof baffles 31 can be two, and the two foolproof baffles 31 are arranged at intervals along the circumference of the inner ring of the fire cover seat 21. One of the foolproof baffles 31 is used to abut against the ignition needle 16, and the other foolproof baffle 31 is used to abut against the thermocouple. In this way, when the fire cover seat 21 is placed on the burner 121, if the user does not align the air inlet 2100 opened on the fire cover seat 21 with the air outlet 12120 on the burner cover 1212, the two foolproof baffles 31 will abut against the ignition needle 16 and the thermocouple 17 respectively, so that the fire cover seat 21 cannot continue to move closer to the burner 121, thereby avoiding the occurrence of misalignment of the fire cover seat installation.

[0080] Another example Fig.12 As shown, in some embodiments of the present application, the number of foolproof baffles 31 can also be three, and the three foolproof baffles 31 are arranged at intervals along the circumference of the inner ring of the fire cover seat 21. In this way, the gap between two adjacent foolproof baffles 31 can be reduced, thereby reducing the possibility that the ignition needle 16 and the thermocouple 17 are inserted into the gap between two adjacent foolproof baffles 31, so as to improve the foolproof effect of the foolproof assembly 3.

[0081] It is understandable that the foolproof effect of the foolproof assembly 3 can be improved by increasing the number of foolproof baffles 31. In this case, in order to ensure sufficient secondary air, when multiple foolproof baffles 31 are provided, the number of first vents 30 is also multiple, and at least one first vent 30 is provided on each foolproof baffle 31. By providing the first vent 30 on the foolproof baffle 31, sufficient secondary air replenishment is ensured.

[0082] As can be seen from the above, by providing the fool-proof component 3 on the inner ring of the fire cover seat 21, the fire cover seat 21 can be prevented from being misplaced during installation by the fool-proof component 3.

[0083] On this basis, if Fig.12 As shown, the gas stove 100 provided in the present application further includes a positioning member 4. The positioning member 4 is connected to the fire cover seat 21, and the positioning member 4 is also located in the inner ring of the fire cover seat 21. A positioning groove 40 is provided on the positioning member 4, and the ignition needle 16 and the thermocouple 17 are located in the positioning groove 40 of the positioning member 4.

[0084] In this way, during the installation process, the user can align the positioning groove 40 of the positioning member 4 with the ignition needle 16 and the thermocouple 17 in advance. This can play a guiding role in the process of installing the fire cover seat 21 on the stove head cover 121, making it easier for the user to correctly install the fire cover seat 21 on the stove head cover 121.

[0085] like Fig.13 As shown, a second ventilation opening 400 is opened on the positioning member 4 , and the second ventilation opening 400 passes through the positioning member 4 .

[0086] In this way, the positioning member 4 arranged on the inner ring of the fire cover seat 21 will not affect the supplement of secondary air, thereby ensuring that the gas can be fully burned.

[0087] See also Fig.12 The positioning groove 40 includes a first positioning groove 401, which is formed on the positioning member 4, and one of the ignition needle 16 and the thermocouple 17 is inserted into the first positioning groove 401. Fig.12 The positioning groove 40 further includes a second positioning groove 402 . The second positioning groove 402 is formed on the positioning member 4 . The other of the ignition needle 16 and the thermocouple 17 is inserted into the second positioning groove 402 .

[0088] For example, the ignition needle 16 is inserted into the first positioning groove 401, and the thermocouple 17 is inserted into the second positioning groove 402. Alternatively, in other embodiments, the thermocouple 17 is inserted into the first positioning groove 401, and the ignition needle 16 is inserted into the second positioning groove 402.

[0089] Thus, during the installation of the fire cover seat 21, the first positioning groove 401 of the positioning groove 40 can be aligned with the ignition needle 16, and the second positioning groove 402 of the positioning groove 40 can be aligned with the thermocouple 17, so as to further improve the accuracy of the fire cover seat 21 during installation and improve the installation efficiency.

[0090] It should be noted that the alignment of the first positioning groove 401 and the ignition needle 16 means that the contour of the projection of the ignition needle 16 on the positioning member 4 coincides with the shape of the opening contour of the first positioning groove 401, or the contour of the projection of the ignition needle 16 on the positioning member 4 completely falls within the opening contour range of the first positioning groove 401. The alignment of the second positioning groove 402 and the thermocouple 17 can refer to the above description and will not be repeated here.

[0091] See also Figure 2 A plurality of gas outlets 12120 are formed on a surface of the burner head 121 near the fire cover seat 21, and the plurality of gas outlets 12120 are all connected to the gas mixing chamber 1210. It should be noted that the plurality of gas outlets 12120 are opened on the gas outlet 12120, and the plurality of gas outlets 12120 are arranged at intervals along the circumference of the burner head cover 1212.

[0092] For example, the number of the gas outlets 12120 on the burner cover 1212 can be three, and the three gas outlets 12120 are spaced apart along the circumference of the burner cover 1212, and the three gas outlets are connected to the gas mixing chamber 1210 of the burner base 1211. In this way, the mixed gas in the gas mixing chamber 1210 can flow out of the gas mixing chamber 1210 more evenly.

[0093] See also Figure 4A plurality of air inlets 2100 are formed on a side surface of the fire cover seat 21 close to the burner head 121. The plurality of air inlets 2100 are arranged at intervals along the circumference of the fire cover seat 21, and one air inlet 2100 is connected to one air outlet 12120. For example, the number of air inlets 2100 on the fire cover seat 21 can be three, and the three air inlets 2100 are connected to the uniform gas cavity 210 of the fire cover seat 21, and the air inlets 2100 are also connected to the air outlet 12120. In this way, the mixed gas in the gas mixing cavity 1210 can flow into the uniform gas cavity 210 of the fire cover seat 21, and then the mixed gas flows out from the uniform gas cavity 210 and is ignited to form a flame.

[0094] On this basis, if Fig.14 As shown ( Fig.14 for Figure 2 (a) A first position limiting portion 12121 is provided on one of the plurality of air outlets 12120. Fig.15 As shown, a second limiting portion 2101 is disposed on one of the plurality of air inlets 2100. The first limiting portion 12121 can be engaged with the second limiting portion 2101.

[0095] See also Fig.14 The first limiting portion 12121 may be a protrusion disposed on the outer peripheral surface of the air outlet 12120. The second limiting portion 2101 may be a groove formed on the peripheral wall of the air inlet 2100. Based on this, when the air outlet 12120 is connected to the air inlet 2100, the protrusion can be engaged in the groove.

[0096] In this way, since the first limiting portion 12121 is provided on the gas outlet 12120 and the second limiting portion 2101 is provided on the gas inlet 2100, the fire cover seat 21 can be installed on the stove head cover 121 only when the gas outlet 12120 provided with the first limiting portion 12121 is connected with the gas inlet provided with the second limiting portion 2101. When the fire cover seat 21 and the stove head cover 121 are installed misaligned, the first limiting portion 12121 set as a convex block will interfere with the gas inlet without the second limiting portion 2101, so that after the fire cover seat 21 is placed on the stove head cover 121, the gas outlet 12120 and the gas inlet 2100 cannot be connected, and the fire cover seat 21 and the fire cover connected thereto are obviously tilted, thereby reminding the user of the misaligned installation.

[0097] In some embodiments of the present application, Fig.16 As shown, one of the multiple air outlets 12120 has a circular opening shape, and the other air outlets 12120 have an elliptical opening shape. Fig.17 As shown, the opening shape of one of the multiple air inlets 2100 is circular, and the opening shapes of the remaining air inlets 2100 are elliptical.

[0098] In this case, the circular air outlet 12120 is connected to the circular air inlet 2100. The other elliptical air outlets 12120 are connected to the other elliptical air inlets 2100.

[0099] In addition, it should be noted that when the projection of the air outlet 12120 with a circular opening shape coincides with the projection of the air inlet with an elliptical opening shape, the contours of the two projections at least partially intersect. That is, even if the air outlet and the air inlet are set opposite to each other, the two will interfere with each other, and there will be no situation where the air outlet and the air inlet are nested. In this way, when the opening shape of the air outlet 12120 is the same as the opening shape of the air inlet 2100, the air outlet 12120 can be connected to the air inlet 2100. When the air outlet 12120 with different opening shapes is set opposite to the air inlet 2100, the two cannot be connected.

[0100] It should be noted that the shapes of the air outlet 12120 and the air inlet 2100 may also be other combinations, such as circular and rectangular, as long as it can be ensured that the air outlet 12120 and the air inlet 2100 can be connected only when the shapes of the air outlet 12120 and the air inlet 2100 are the same.

[0101] In other embodiments of the present application, a plurality of air outlets 12120 are arranged at intervals along the circumference of a side surface of the burner head 121 close to the fire cover seat 21, and the intervals between the plurality of air outlets 12120 are different along the circumference of a side surface of the burner head 121 close to the fire cover seat 21. Based on this, a plurality of air inlets 2100 are arranged at unequal intervals along the circumference of a side surface of the fire cover seat 21 close to the burner head 121, and the plurality of air outlets 12120 are connected to the plurality of air inlets 2100.

[0102] In this way, during the installation of the fire cover seat 21, if the distance between two adjacent air outlets 12120 is different from the distance between two adjacent air inlets 2100, the air outlets 12120 cannot be connected to the air inlets 2100. In this way, when the air outlets 12120 cannot be connected to the air inlets 2100, the fire cover seat 21 and the fire cover 22 connected thereto will be tilted, thereby reminding the user of misalignment during installation.

[0103] 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.

[0104] 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.
