[0059] The present application provides a gas stove, which combines Figure 1 , Figure 2 and Figure 7 In some embodiments of the present application, the gas stove comprises a panel 1000, a burner 4000, a jet device 5000 and a driving device 6000, the burner 4000 is designed to be detachably mounted on the panel 1000, the jet device 5000 is designed to be movably arranged, when the gas stove is needed to be used, the burner 4000 is mounted on the panel 1000 and the jet device 5000 is driven to a first position, so that the jet port 5200 is aligned with the air inlet 4100, when the gas stove is needed to be cleaned, the burner 4000 is detached and the jet device 5000 is driven to a second position, so as to facilitate the cleaning of the panel 1000.

[0060] Specifically, the gas stove comprises a frame 2000, the frame 2000 comprises a bottom plate 2100 and a surrounding plate 2200 arranged on the bottom plate 2100, generally, the frame 2000 is made of sheet metal, the bottom plate 2100 and the surrounding plate 2200 are formed by bending the sheet metal, the panel 1000 needs to be installed on the surrounding plate 2200 to form a containing cavity 3000 with the frame 2000, and the panel 1000 and the frame 2000 form the skeleton of the gas stove for supporting the installation of the remaining components.

[0061] The burner 4000 is installed on the panel 1000, the so-called burner 4000 can receive and burn gas, for example, the burner 4000 comprises an injection pipe, a gas distribution disc, a fire cover, a support and the like. The burner 4000 is installed on the panel 1000 and is detachable relative to the panel 1000, when the gas stove is used, the burner 4000 is placed on the panel 1000, when the panel 1000 needs to be cleaned, the burner 4000 can be detached to facilitate the cleaning of the panel 1000.

[0062] The burner 4000 needs to cooperate with the gas injection device 5000, the gas injection device 5000 is a component for providing gas, the gas injection device 5000 needs to receive an external gas source, which can be pipeline natural gas, bottled petroleum gas or other types of gas source, the gas injection device 5000 is connected to the external gas source, under the action of pressure, the gas can be sprayed from the gas injection port 5200 of the gas injection device 5000, the gas injection port 5200 of the gas injection device 5000 needs to be aligned with the gas inlet 4100 of the burner 4000, the gas sprayed from the gas injection port 5200 of the gas injection device 5000 enters the burner 4000 through the gas inlet 4100, and then flows out of the burner 4000, and then is ignited to form a flame. Generally, the gas injection port 5200 and the gas inlet 4100 are not completely sealed and docked, so that when the gas is injected into the gas inlet 4100, the external air is simultaneously introduced, the external air and the gas are mixed to make the gas burn more fully. It can be understood that the gas inlet 4100 can be formed by the injection pipe, when the burner 4000 is in a burning state, the gas is forced to flow into the burner 4000, avoiding leakage of the gas at the gas inlet 4100.

[0063] The air jet device 5000 needs to cooperate with the driving device 6000, and under the driving of the driving device 6000, the air jet device 5000 can be moved, so as to avoid that the cleaning of the panel 1000 is hindered by the air jet device 5000. Specifically, the air jet device 5000 needs to be drivingly connected with the driving device 6000, that is, the driving connection means that the power is transmitted, and the driving device 6000 transmits the force to the air jet device 5000, so that the movement state of the air jet device 5000 is changed. The air jet device 5000 moves under the driving of the driving device 6000, so as to be in the second position and the first position. When the driving device 6000 drives the air jet device 5000 to move to the first position, the air jet device 5000 is exposed above the panel 1000, that is, higher than the panel 1000 in the up-down direction, so as to facilitate the alignment of the air jet port 5200 and the air inlet 4100. When the driving device 6000 drives the air jet device 5000 to move to the second position, the air jet device 5000 is hidden in the panel 1000, that is, at least not higher than the panel 1000 (flush with the panel 1000 or lower than the panel 1000), so as to facilitate the cleaning of the panel 1000.

[0064] The movement process of the air jet device 5000 is briefly described as follows:

[0065] When the gas stove needs to be used, the burner 4000 is placed on the panel 1000, the burner 4000 is supported, the driving device 6000 is controlled to act, and the driving device 6000 drives the air jet device 5000 to the first position. At this time, the air jet port 5200 of the air jet device 5000 is aligned with the air inlet 4100, and the air jet device 5000 is used to supply air to the burner 4000.

[0066] When the panel 1000 needs to be cleaned, the burner 4000 is detached from the panel 1000, the driving device 6000 is controlled to act, and the driving device 6000 drives the air jet device 5000 to the second position. When the air jet device 5000 is in the second position, it is not higher than the panel 1000. It can be that the air jet device 5000 is just flush with the panel 1000, or the air jet device 5000 is located below the panel 1000. Therefore, the upper surface of the panel 1000 is not hindered by the burner 4000 and the air jet device 5000, so that the panel 1000 is conveniently cleaned, the panel 1000 has no dead angle that is difficult to clean, and the use experience is improved.

[0067] There are various ways for the driving device 6000 to drive the air jet device 5000 to move to the first position and the second position. Since the air jet device 5000 is higher than the panel 1000 when it is in the first position, and is not higher than the panel 1000 when it is in the second position, that is, the first position is higher than the second position. In order to facilitate the movement of the air jet device 5000 between the first position and the second position, the air jet device 5000 isFigures 3 to 9 As shown, in some embodiments of this application, the jet device 5000 moves up and down in the vertical direction under the drive of the drive device 6000. Since the jet device 5000 needs to be connected to an external air source, the up and down movement of the jet device 5000 has a shorter movement path, which can reduce the structural complexity.

[0068] Combination Figure 4 , Figure 6 and Figure 9 As shown, in some embodiments of this application, the drive device 6000 includes a motor 6100, a worm gear 6200, a worm wheel 6310, and a lifting component 6500. Through the cooperation of the motor 6100, the worm gear 6200, the worm wheel 6310, and the lifting component 6500, the lifting component 6500 is driven to move up and down. The lifting component 6500 needs to be connected to the jet device 5000. In this way, the lifting component 6500 can drive the jet device 5000 to move up and down. Due to the cooperation of the worm gear 6200 and the worm wheel 6310, the worm gear 6200 and the worm wheel 6310 can achieve self-locking to prevent the jet device 5000 from shaking up and down.

[0069] Specifically, the motor 6100 is a component that outputs rotational power when energized. The motor 6100 is driven to drive the worm gear 6200, thereby driving the worm gear 6200 to rotate. The worm wheel 6310 needs to mesh with the worm gear 6200 for transmission. The rotation of the worm gear 6200 will drive the worm wheel 6310 to rotate. The worm wheel 6310 is provided with a worm wheel shaft 6320. It can be understood that the worm wheel shaft 6320 is located at the axial center of the worm wheel 6310. The worm wheel shaft 6320 and the worm wheel 6310 can be integrally formed. In this way, when the worm wheel 6310 rotates, it can drive the worm wheel shaft 6320 to rotate. The worm wheel shaft 6320 is driven to drive the lifting component 6500, thereby driving the lifting component 6500 to move up and down. While the lifting component 6500 is moving up and down, it can also drive the jet device 5000 to move up and down.

[0070] Because of the self-locking characteristic of the worm gear 6200 and worm wheel 6310, the worm wheel 6310 can only be driven to rotate by the worm gear 6200. When the worm gear 6200 is not rotating, the worm wheel 6310 is locked by the worm gear 6200 and cannot rotate. Thus, when the motor 6100 stops driving the worm gear 6200, the worm wheel 6310 will no longer rotate, meaning the lifting component 6500 will no longer move up and down. This prevents accidental rotation between the worm wheel 6310 and the worm gear 6200 when the motor 6100 drives the jet device 5000 to the predetermined position, which could cause the jet device 5000 to deviate from the predetermined position. It is precisely because of the self-locking of the worm wheel 6310 and the worm gear 6200 that the jet device 5000 is prevented from wobbling up and down, making the positioning of the jet device 5000 more accurate. In addition, the worm gear 6200 and worm wheel 6310 work together to form a reduction structure, which can increase the output torque and reduce the output speed. For example, the reduction ratio is 22, which makes the jet device 5000 rise slowly and more precisely controlled.

[0071] Understandably, the motor 6100 can rotate in both directions to control the lifting component 6500. For example, when the motor 6100 rotates forward, it controls the lifting component 6500 to rise, thereby moving the jet device 5000 to the first position; when the motor 6100 rotates in reverse, it controls the lifting component 6500 to fall, thereby moving the jet device 5000 to the second position. Alternatively, the motor 6100 can also control the lifting component 6500 to fall when rotating forward, and to rise when rotating in reverse.

[0072] Continue to combine Figure 4 , Figure 6 and Figure 9 As shown, in some embodiments of this application, the lifting component 6500 includes a threaded shaft 6510 and a sleeve 6520. The sleeve 6520 and the threaded shaft 6510 are screwed together. The sleeve 6520 can convert the rotational motion of the threaded shaft 6510 into a linear reciprocating motion along the axial direction of the sleeve 6520, thereby driving the jet device 5000 to move up and down.

[0073] Specifically, the worm gear shaft 6320 needs to be driven to connect with the threaded shaft 6510. As mentioned above, this drive connection enables force transmission. Therefore, the drive connection between the worm gear shaft 6320 and the threaded shaft 6510 can be implemented in various ways. For example, the worm gear shaft 6320 and the threaded shaft 6510 can be integrally formed, or they can be two separate components connected by a coupling 6400. Compared to the former, the latter, by using the coupling 6400, reduces the design complexity of the worm gear shaft 6320 and the threaded shaft 6510 and also avoids overload.

[0074] The sleeve 6520 has an internal thread, while the threaded shaft 6510 has an external thread, for example, the internal thread of the sleeve 6520 is a right-handed 4-thread internal thread, while the external thread of the threaded shaft 6510 is a right-handed 4-thread external thread, and the two are screwed together so that the sleeve 6520 is sleeved on the threaded shaft 6510. The sleeve 6520 is screwed on the threaded shaft 6510, when the motor 6100 starts, the motor 6100 drives the worm gear 6310 to rotate through the worm 6200, thereby driving the worm shaft 6320 to rotate, and the worm shaft 6320 drives the threaded shaft 6510 to rotate. Since the sleeve 6520 can convert the rotary motion of the threaded shaft 6510 into linear reciprocating motion, the sleeve 6520 can move along the axial direction of the threaded shaft 6510 while the threaded shaft 6510 rotates. The sleeve 6520 needs to be drivingly connected to the air jet device 5000, so as to drive the air jet device 5000 to move up and down.

[0075] Since the sleeve 6520 needs to be screwed with the threaded shaft 6510, in order to avoid interference of the threaded shaft 6510 with the air jet device 5000, the sleeve 6520 needs to be provided with a certain height, so that when the air jet device 5000 rises, the sleeve 6520 can still ensure the screwing with the threaded shaft 6510, and when the air jet device 5000 descends, interference with the threaded shaft 6510 can be avoided, so as to facilitate driving connection with the air jet device 5000.

[0076] It can be understood that there are many ways to convert the rotary motion of the threaded shaft 6510 into linear reciprocating motion by the sleeve 6520, for example, a way similar to the screw nut transmission is adopted, that is, a constraint is applied to the sleeve 6520 so that the sleeve 6520 cannot rotate with the threaded shaft 6510, but can only move in the axial direction of the threaded shaft 6510 under the action of the constraint. The constraint on the sleeve 6520 can be realized in the form of a guide rail arranged in the axial direction of the threaded shaft 6510, and a force interaction exists between the guide rail and the sleeve 6520. Of course, the constraint can also be in other forms.

[0077] In this embodiment, the following method is used to realize the lifting of the sleeve 6520. Figure 4 , Figure 6 and Figure 9As shown in FIGS. 1 1 and 12, in some embodiments of the present application, the lifting component 6500 further comprises a first support 6530, the first support 6530 is provided with an internal thread, and the sleeve 6520 is provided with an external thread, for example, the internal thread of the first support 6530 is a left-handed 4-line internal thread, and the external thread of the sleeve 6520 is a left-handed 4-line external thread, the sleeve 6520 is screwed with the first support 6530 through the external thread of the sleeve 6520, so that the sleeve 6520 is placed inside the first support 6530, and the first support 6530 needs to be fixedly installed, for example, the first support 6530 is fixed to the bottom plate 2100 (detailed below), so that through the screwing of the threaded shaft 6510 and the sleeve 6520, the sleeve 6520 and the first support 6530 are screwed, and when the threaded shaft 6510 rotates, the sleeve 6520 can be driven to move up and down. It can be understood that, by screwing the sleeve 6520 and the first support 6530 with the threaded shaft 6510, the helix angle of the thread can be designed to be larger, so that the transmission efficiency can be improved, the energy loss can be reduced, and more accurate control can be achieved.

[0078] It can be understood that, when the sleeve 6520 is lifted through the cooperation of the threaded shaft 6510, the sleeve 6520 and the first support 6530, the sleeve 6520 rotates synchronously during the lifting of the sleeve 6520. In order to smoothly drive the air jet device 5000 to move up and down, in combination with Figure 4 、 Figure 6 、 Figure 9 、 Figure 11 and Figure 12 As shown in FIGS. 1 1 and 12, in some embodiments of the present application, the air jet device 5000 is provided with a clamping groove 5130, the top end of the sleeve 6520 is clamped in the clamping groove 5130, and the top end of the sleeve 6520 and the clamping groove 5130 form a clearance fit, so that the sleeve 6520 can rotate in the clamping groove 5130 during the lifting of the sleeve 6520, thereby driving the air jet device 5000 to move up and down.

[0079] Specifically, the air jet device 5000 can form the clamping groove 5130 in various ways, for example, in combination with Figure 11 and Figure 12As shown, the gas jet device 5000 comprises a lower support platform 5120 and an upper support platform 5110, the lower support platform 5120 is provided with a first through hole 5121 and a groove 5122 surrounding the first through hole 5121, the top end of the sleeve 6520 is slightly larger in diameter than the rest of the sleeve 6520, the sleeve 6520 passes through the first through hole 5121 so that the top end of the sleeve 6520 is clamped in the groove 5122, the upper support platform 5110 and the lower support platform 5120 are connected in overlap to be fixed to each other, thus the upper support platform 5110 covers the first through hole 5121 and the groove 5122 to form a clamping groove 5130, thus realizing the connection of the sleeve 6520 and the gas jet device 5000, when the sleeve 6520 rises, the sleeve 6520 acts on the upper support platform 5110, thereby driving the entire gas jet device 5000 to rise, when the sleeve 6520 descends, the sleeve 6520 acts on the lower support platform 5120, thereby driving the entire gas jet device 5000 to descend.

[0080] Further, as shown in Figure 4 , Figure 6 and Figure 9 , in order to avoid the gas jet device 5000 from rotating with the sleeve 6520, the gas stove is further provided with a guide column 7400, the guide column 7400 is fixedly arranged, the guide column 7400 is fixed in various ways, for example, the guide column 7400 is fixed to the bottom plate 2100, or the guide column 7400 is fixed to the first support 6530, at the same time, the guide column 7400 needs to pass through the gas jet device 5000, for example, when the gas jet device 5000 comprises a lower support platform 5120 and an upper support platform 5110, the guide column 7400 needs to pass through the lower support platform 5120 and the upper support platform 5110, when the sleeve 6520 rotates, due to the constraint of the guide column 7400, the gas jet device 5000 can be prevented from rotating with the sleeve 6520, but will realize the up and down movement under the action of the sleeve 6520 along the guide column 7400. It can be understood that, in order to reduce the friction between the guide column 7400 and the gas jet device 5000, a copper sleeve can be arranged at the part where the guide column 7400 passes through the gas jet device 5000.

[0081] As mentioned above, the gas stove comprises a frame 2000, the panel 1000 covers the frame 2000 to form a containing cavity 3000, the gas jet device 5000 is designed to be contained in the containing cavity 3000 when in the second position, realizing the hidden arrangement of the gas jet device 5000, avoiding the gas jet device 5000 from occupying the space outside, and being safer.

[0082] Specifically, when the jet device 5000 is driven to ascend, at least part of the jet device 5000 is out of the accommodating cavity 3000, and when the jet device 5000 is driven to descend, the jet device 5000 can move into the accommodating cavity 3000, so that the jet device 5000 can make full use of the space of the accommodating cavity 3000. It can be understood that, since the jet device 5000 needs to be connected with an external gas source, corresponding pipelines are arranged in the accommodating cavity 3000 and connected with the jet device 5000, and the jet device 5000 can move in and out of the accommodating cavity 3000 to facilitate the connection with the pipelines. Moreover, when the panel 1000 needs to be cleaned, the jet device 5000 moves into the accommodating cavity 3000 and does not occupy external space, which greatly optimizes the installation space of the gas stove, and the jet device 5000 in the accommodating cavity 3000 is also protected by the frame 2000 and the panel 1000 and is not easily damaged by external collision, improving safety.

[0083] Since the jet device 5000 is located in the accommodating cavity 3000 when in the second position, and the jet device 5000 needs to be driven to connect with the driving device 6000, in order to avoid that the accommodating cavity 3000 is too large to occupy the kitchen space, in combination with Figure 3 and Figure 4 It is shown that, in some embodiments of the present application, the motor 6100, the worm 6200 and the worm gear 6310 of the driving device 6000 are arranged outside the accommodating cavity 3000, avoiding increasing the space of the accommodating cavity 3000, so as to avoid that the gas stove occupies too large space.

[0084] Specifically, the worm gear 6310, the worm 6200 and the motor 6100 are fixed on the bottom plate 2100 of the frame 2000, that is, the bearing of the worm gear 6310, the worm 6200 and the motor 6100 is realized through the bottom plate 2100. For example, the gas stove comprises a second support 7100 and a third support 7200, the motor 6100 is fixed on the third support 7200, the third support 7200 accommodates the worm 6200 and the worm gear 6310 which are in mesh with each other, the worm shaft 6320 extends out of the third support 7200, and the third support 7200 is provided with a bearing 7210 supporting the rotation of the worm shaft 6320. The third support 7200 is fixed on the second support 7100, and the second support 7100 is fixed to the bottom plate 2100. By arranging the worm gear 6310, the worm 6200 and the motor 6100 below the bottom plate 2100, the space of the accommodating cavity 3000 is avoided to be occupied. At the same time, the motor 6100 is in a powered state to realize movement, so that the motor 6100 is exposed outside the accommodating cavity 3000, which is more convenient for maintenance and replacement of the motor 6100 without the need to disassemble the entire gas stove.

[0085] In combination with Figure 3 and Figure 4As shown, in some embodiments of the present application, when the gas jet device 5000 is accommodated in the accommodating cavity 3000 in the second position, and needs to be raised, the gas jet device 5000 is raised from the accommodating cavity 3000, therefore, in order to avoid the length of the sleeve 6520 being too long, in some embodiments of the present application, the first support 6530 is arranged in the accommodating cavity 3000, and the bottom plate 2100 is fixed, so that the length of the sleeve 6520 is adapted to the first support 6530, and the sleeve 6520 is prevented from moving and extending below the gas stove. When the first support 6530 is arranged in the accommodating cavity 3000, the threaded shaft 6510 needs to be drivingly connected through the bottom plate 2100 and the worm gear shaft 6320, and it can be understood that the part of the threaded shaft 6510 located in the accommodating cavity 3000 has external threads, and the part of the threaded shaft 6510 located outside the accommodating cavity 3000 has no external threads, and the fourth support 7300 is fixed on the bottom plate 2100 and located below the bottom plate 2100, the bearing 7310 is arranged on the fourth support 7300, and the part of the threaded shaft 6510 located outside the accommodating cavity 3000 passes through the bearing 7310 on the fourth support 7300, so that the threaded shaft 6510 rotates more stably under the driving of the worm gear shaft 6320.

[0086] In combination Figure 4 As shown, in some embodiments of the present application, the opening 1100 is arranged on the panel 1000, and the lifting process of the gas jet device 5000 passes through the opening 1100, and the arrangement of the opening 1100 makes the panel 1000 have better integrity, and when the gas jet device 5000 is lowered, the gas jet device 5000 can be hidden in the gas stove as much as possible.

[0087] Specifically, the opening 1100 is in communication with the accommodating cavity 3000, when the gas jet device 5000 is controlled to rise, the gas jet device 5000 moves upward from the accommodating cavity 3000 and is exposed above the panel 1000 through the opening 1100, and when the gas jet device 5000 is controlled to lower, the gas jet device 5000 moves into the accommodating cavity 3000 through the opening 1100. It can be understood that the opening 1100 is in the form of a closed ring, for example, the opening 1100 is circular, and the periphery of the opening 1100 can cover the space below the panel 1000 as much as possible, so as to avoid the exposure of the space below the panel 1000, and when the gas jet device 5000 is lowered to the second position, the gas jet device 5000 can be hidden in the gas stove as much as possible. In addition, the panel 1000 is provided with the opening 1100 instead of a notch, which can also ensure the structural strength of the panel 1000 to a certain extent.

[0088] Due to the arrangement of the opening 1100, in order to prevent external objects from accidentally entering the accommodating cavity 3000 through the opening 1100 when the gas jet device 5000 is in the second position, in combination Figures 7 to 10As shown, the gas stove further comprises a cover plate 7500. When the gas jet device 5000 is lowered to the second position, foreign matter can enter the accommodating cavity 3000 through the opening 1100 during the user's cleaning of the panel 1000, which poses a safety hazard. Therefore, the cover plate 7500 is arranged to cover the opening 1100, so that the entire panel 1000 forms a relatively flat plane, which is more conducive to the cleaning of the panel 1000.

[0089] The cover plate 7500 covers the opening 1100 in various ways. For example, the cover plate 7500 is directly mounted on the panel 1000 to cover the opening 1100. Although this scheme can cover the opening 1100, the user needs to remove the cover plate 7500 before the gas jet device 5000 is raised, otherwise the cover plate 7500 will be lifted by the gas jet device 5000 and fall off.

[0090] In other embodiments, the cover plate 7500 is fixed on the gas jet device 5000 and moves with the movement of the gas jet device 5000. This scheme also has various forms.

[0091] For example, when the gas stove needs to be used, the gas jet device 5000 is controlled to be raised. Since the cover plate 7500 is fixed on the gas jet device 5000, the cover plate 7500 can be raised with the raising of the gas jet device 5000. When the gas jet device 5000 is raised to the first position, the user needs to remove the cover plate 7500 and then install the burner 4000 on the panel 1000. When the gas stove needs to be cleaned, the gas jet device 5000 is controlled to be lowered to the second position, and then the user installs the cover plate 7500 on the gas jet device 5000.

[0092] For another example, when the gas stove needs to be used, the gas jet device 5000 is controlled to be raised, and the cover plate 7500 is raised with the raising of the gas jet device 5000. When the gas jet device 5000 is raised to the first position, the cover plate 7500 does not need to be removed, and the alignment of the gas jet port 5200 and the air inlet port 4100 can be achieved after the installation of the burner 4000. When the gas stove needs to be cleaned, the gas jet device 5000 is controlled to be lowered to the second position, and the cover plate 7500 is lowered with the lowering of the gas jet device 5000 and then covers the opening 1100.

[0093] It can be understood that, during the use or cleaning of the gas stove, the disassembly of the burner 4000 and the raising and lowering of the gas jet device 5000 are not distinguished in sequence. The burner 4000 can be disassembled first and then the gas jet device 5000 is raised and lowered, or the gas jet device 5000 can be raised and lowered first and then the burner 4000 is disassembled.

[0094] In combination Figures 3 to 6 and Figure 11As shown, in some embodiments of this application, when the jet device 5000 rises to the first position, the support platform 5100 of the jet device 5000 blocks the opening 1100. The support platform 5100 can be formed by combining the upper support platform 5110 and the lower support platform 5120 mentioned above. Of course, the support platform 5100 can also adopt other structures.

[0095] Combination Figure 1 , Figure 3 and Figure 4 As shown in some embodiments of this application, when the jet device 5000 rises to the first position, foreign objects may drift from top to bottom to the opening 1100 when cooking with a gas stove. To avoid this, a baffle 4200 can be provided on the burner head 4000. For example, the baffle 4200 extends approximately horizontally, and the size of the baffle 4200 is much larger than the opening 1100. For example, the size of the baffle 4200 is two, three, or more times the size of the opening 1100. In this way, the baffle 4200 can block the opening 1100 from top to bottom.

[0096] Since the burner head 4000 is detachable from the panel 1000, in order to ensure that the burner head 4000 can be aligned with the jet nozzle 5200 when installed on the panel 1000, and also to facilitate disassembly relative to the panel 1000, combined with... Figure 3 , Figure 4 and Figure 13 As shown, in some embodiments of this application, the burner head 4000 is provided with a plug 4300 and the jet device 5000 is provided with a socket 5300. When the burner head 4000 is installed on the panel 1000, the plug 4300 on the burner head 4000 is aligned with the socket 5300 of the jet device 5000 and inserted. The cooperation between the plug 4300 and the socket 5300 realizes the positioning of the burner head 4000 and ensures the alignment of the jet port 5200 and the air inlet 4100.

[0097] Since the socket 5300 is located in the jet device 5000, when the plug 4300 is inserted into the socket 5300, the relative position between the jet device 5000 and the burner head 4000 can be ensured to the greatest extent. The burner head 4000 is positioned only on the panel 1000. The socket 5300 and the plug 4300 ensure that there is a positioning relationship between the jet device 5000 and the burner head 4000, so that the alignment of the jet port 5200 and the air inlet 4100 is more accurate.

[0098] The gas stove disclosed in the application can be a single gas stove or can be integrated with other household appliances to form a combined appliance, for example, an integrated stove integrated with a smoke machine, an oven stove integrated with an oven, and the gas stove in the combined appliance adopts the technical solutions of the above embodiments and thus has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0099] The above is only the preferred embodiment of the application, and does not limit the patent scope of the application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made by using the content of the application specification and drawings within the concept of the application is included in the patent protection scope of the application.
