At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0056] As described in the foregoing background art section, during the use of gas stoves in the prior art, the gas flow rate and the flame state cannot be automatically switched according to the placement state of the cookware on the gas stove top, so during the use of the gas stove, it is easy to cause waste of gas.

[0057] Based on this, as Figure 1As shown in the figure, a gas stove is provided, including: a burner assembly 1, a burner component 2, a valve body assembly 3, a lifting component 4, and a controller assembly 5. Among them, the burner component 2 is arranged above the burner assembly 1, the lifting component 4 is arranged in the central area of the burner component 2, the valve body assembly 3 is connected to the burner assembly 1, and both the valve body assembly 3 and the lifting component 4 are connected to the controller assembly 5.

[0058] Specifically, the burner assembly 1 in this embodiment is used to achieve the mixing of gas and air and provide a position for placing the burner component 2. The burner component 2 in this embodiment is installed at a certain distance above the burner assembly 1 and is used to receive the gas transmitted by the burner assembly 1 and ignite the gas to generate a flame. The valve body assembly 3 in this embodiment is used to achieve the switching of the on-off state of the gas stove and control the gas flow rate provided to the burner assembly 1. The lifting component 4 in this embodiment is installed in the central area of the burner component 2 and can change its telescopic state according to the placement state of the cookware 8. The control component in this embodiment is respectively connected to the lifting component 4 and the valve body assembly 3, and is mainly used to determine the control signal sent to the valve body assembly 3 according to the telescopic state of the lifting component 4, so as to control the on-off state of the valve body assembly 3 according to the telescopic state of the lifting component 4.

[0059] Specifically, the valve body assembly 3 provides gas with a preset flow rate for the burner assembly 1 according to the real-time state of the lifting component 4, so that the burner component 2 generates a flame, where the real-time state includes a compressed state and an extended state.

[0060] When the lifting component 4 in this embodiment is in the compressed state, the controller assembly 5 receives the electrical signal transmitted back by the lifting component 4, determines the real-time state of the lifting component 4 as the compressed state according to this electrical signal, and then sends a corresponding control signal to the valve body assembly 3, so that the valve body assembly 3 normally provides gas for the burner assembly 1, and the burner component 2 provides a central flame or an outer ring flame according to the opening degree of the valve body assembly 3. When the lifting component 4 is in the extended state, the control component sends a corresponding control signal to the valve body assembly 3, so that the valve body assembly 3 provides gas for the burner assembly 1 according to a limited amount, and the burner component 2 only provides a central flame.

[0061] In summary, this embodiment provides a gas stove. By arranging a lifting component 4 in the central area of the burner component 2, real-time monitoring of whether a cooking utensil is placed on the burner component 2 can be achieved. The controller assembly 5 can accurately determine the placement state of the cooking utensil according to the change of the status signal transmitted by the lifting component 4. When the real-time state of the lifting component 4 changes, the controller assembly 5 immediately sends a control signal to the valve body assembly 3 to adjust the gas flow rate delivered by the valve body assembly 3 to the burner assembly 1, so as to accurately control the flame provided by the burner component 2, realizing that when the cooking utensil leaves the stove top, the supplied gas volume is automatically reduced, the flame range provided by the burner component 2 is reduced, and gas energy is effectively saved.

[0062] In a specific embodiment, the startup process of the gas stove includes opening the valve body assembly 3 to supply gas to the burner assembly 1 through a gas pipeline. The burner assembly 1 mixes gas and air, and the burner component 2 ignites the mixed gas delivered by the burner assembly 1 and generates an outer ring flame and a central flame to heat the cooking utensil placed above the burner assembly 1.

[0063] When the gas stove is in the ignited state, as Figure 2 shown, if the cooking utensil 8 is placed above the burner assembly 1, the lifting component 4 will be subjected to a downward force from the cooking utensil 8 and enter the compressed state. When the lifting component 4 is in the compressed state, it will send a compression state signal to the controller assembly 5. The controller assembly 5 sends a conduction control signal to the valve body assembly 3 according to the compression state signal. The controller assembly 5 controls the valve body assembly 3 to be fully conducted, and the valve body assembly 3 supplies gas to the burner assembly 1 at the first gas flow rate, so that the burner component 2 generates a central flame and an outer ring flame to heat the cooking utensil 8.

[0064] If the cooking utensil 8 leaves above the burner assembly 1, the lifting component 4 is no longer subjected to a downward force from the cooking utensil 8, and the lifting component 4 enters the extended state with the internal force. When the lifting component 4 is in the extended state, the controller assembly 5 receives the extension state signal sent by the lifting component 4. The controller assembly 5 sends a shut-off control signal to the valve body assembly 3 according to the extension state signal. The controller assembly 5 controls the valve body assembly 3 to be partially conducted, and the valve body assembly 3 supplies gas to the burner assembly 1 at the second gas flow rate, so that the burner component 2 generates a central flame, where the first gas flow rate is greater than the second gas flow rate.

[0065] In a specific embodiment, as Figure 3As shown, before starting the gas stove, if the cookware 8 is not placed above the burner assembly 1, the lifting member 4 will not be subjected to the downward force of the cookware 8. The lifting member 4 remains in the extended state under the internal force. When the lifting member 4 is in the extended state, the controller assembly 5 cannot detect an electrical signal from the lifting member 4, thereby determining that the real-time state of the lifting member 4 is the extended state. The controller assembly 5 controls the valve body assembly 3 to always maintain a partially open state. If the gas stove is started at this time, the valve body assembly 3 can only supply gas to the burner assembly 1 at the second gas flow rate, so that the burner member 2 generates a central flame at the second gas flow rate.

[0066] In the specific implementation process, the open state of the valve body assembly 3 determines the open state of the corresponding gas pipeline. When the valve body assembly 3 is in the fully open state, all gas pipelines are in the open state and can supply more gas to the burner assembly 1. When the valve body assembly 3 is partially open, only some gas pipelines are in the open state and some gas pipelines will be closed. At this time, only a small amount of gas can be supplied to the burner assembly 1. It should be noted that the flame generated by the burner member 2 will become smaller as the gas decreases and larger as the gas increases.

[0067] The structure of the lifting member 4 is configured such that when the cookware 8 is placed above the burner assembly 1, the cookware 8 will come into contact with the lifting member 4, and the lifting member 4 will move downward under the action of the cookware 8 and thus enter the compressed state. When the cookware 8 leaves above the burner assembly 1, the lifting member 4 will not be subjected to the downward force of the cookware 8 and thus remain in the extended state. It should be noted that when the lifting member 4 is subjected to sufficient downward force, it will enter the compressed state, not limited to the force of the cookware 8.

[0068] In one embodiment, as Figure 1 shown, the gas stove further includes: a support frame 6 and a bottom case 7.

[0069] The valve body assembly 3, the controller assembly 5, the burner assembly 1, and the support frame 6 are all fixedly installed on the bottom case 7. The support frame 6 is arranged around the burner assembly 1 and is used to support the cookware 8. The height of the support frame 6 relative to the bottom case 7 is less than the height of the lifting member 4 relative to the bottom case 7 when the lifting member 4 is in the extended state.

[0070] In a specific embodiment, various structures required for the gas stove in the actual application process can be installed on the bottom case 7. For example, a liquid receiving tray. The specific structures provided on the bottom case 7 in this embodiment are not limited and can be expanded according to the needs of the actual application scenario.

[0071] In the specific implementation process, from Figure 1It can be seen that the support frame 6 is arranged around the burner assembly 1 and the burner component 2. The support frame 6 is used to support the cookware 8 and make the center of the bottom of the cookware 8 be at the center of the flame provided by the burner, so as to better heat the cookware 8.

[0072] In the actual application process, the shape and the setting position of the support frame 6 can be adaptively configured according to the needs of the actual application scenario. In this embodiment, the shape and the actual setting position of the support frame 6 are not limited.

[0073] Specifically, the height of the support frame 6 relative to the highest point of the bottom shell 7 plane is less than the height of the lifting component 4 in the extended state relative to the highest point of the bottom shell 7 plane. Thus, the lifting component 4 can accurately monitor the placement state of the cookware 8, such as a frying pan, placed on the support frame 6.

[0074] It should be noted that in this embodiment, the specific height difference between the support frame 6 and the lifting component 4 needs to ensure that the lifting component 4 does not generate electrical signals at all in the extended state and stably generates electrical signals in the compressed state, so as to assist the controller assembly 5 to analyze the real-time state of the lifting component based on the electrical signals. The specific numerical value of the height difference can be determined according to the shapes of most cookwares 8 used in the market and the shape of the support frame 6, and will not be exemplified one by one here.

[0075] In one of the embodiments, as Figure 1 shown, the valve body assembly 3 includes an outer ring gas passage 301, a central gas passage 302 and a switching valve 303. The burner component 2 includes an outer ring burner cap 201 and a central burner cap 202. Among them, the switching valve 303 is arranged in the pipeline of the outer ring gas passage 301. The switching valve 303 is connected to the controller assembly 5. The outer ring burner cap 201 is connected to the outer ring gas passage 301, and the central burner cap 202 is connected to the central gas passage 302.

[0076] In the specific implementation process, the outer ring gas passage 301 supplies gas to the outer ring burner cap 201, and the outer ring burner cap 201 generates an outer ring flame according to the gas supplied by the outer ring gas passage 301. The central gas passage 302 supplies gas to the central burner cap 202, and the central burner cap 202 generates a central flame according to the gas supplied by the central gas passage 302.

[0077] When the lifting component 4 is in the compressed state, the controller assembly 5 controls the switching valve 303 to conduct, so as to conduct the outer ring gas passage 301, thereby supplying gas to the outer ring burner cap 201, and thus generating the outer ring flame on the outer ring burner cap 201.

[0078] When the lifting component 4 is in the extended state, the controller assembly 5 controls the switching valve 303 to cut off, so as to close the outer ring gas passage 301, thereby stopping supplying gas to the outer ring burner cap 201, and thus extinguishing the outer ring flame on the outer ring burner cap 201.

[0079] In one embodiment, as Figure 1 shown, when the gas stove is in the ignition state, if the lifting member 4 is in the compressed state, flames are generated in both the central burner cap 202 and the outer ring burner cap 201 of the burner member 2. If the lifting member 4 is in the extended state, a flame is generated in the central burner cap 202 of the burner member 2.

[0080] In a specific embodiment, as Figure 4 and Figure 5 shown, the switch valve 303 includes a plugging member 3031, and the size of the plugging member 3031 is the same as the pipe diameter of the outer ring gas passage 301.

[0081] Specifically, as Figure 4 shown, when the lifting member 4 is in the compressed state, the controller assembly 5 controls the plugging member 3031 of the switch valve 303 to remain in the open state, then the plugging member 3031 is received in the pipe cavity of the outer ring gas passage 301 and does not block the flow of gas in the outer ring gas passage 301. It should be noted that the specific installation position of the plugging member 3031 in the outer ring gas passage 301 can be configured according to the needs of the actual application scenario. For example, the installation position of the switch valve 303 can be at the corner of the outer ring gas passage 301 as Figure 5 shown. In some embodiments, the installation position of the plugging member 3031 of the switch valve 303 can also be the inlet or outlet of the outer ring gas passage 301.

[0082] As Figure 5 shown, when the lifting member 4 is in the extended state, the controller assembly 5 controls the plugging member 3031 of the switch valve 303 to enter the off state, then the plugging member 3031 pops out to block the flow of gas in the outer ring gas passage 301. It should be noted that when the plugging member 3031 is in the popped state, since the size of the plugging member 3031 is exactly the same as the pipe diameter of the outer ring gas passage 301, the plugging member 3031 will completely block the outer ring gas passage 301 to stop the gas supply of the outer ring gas passage 301.

[0083] In one of the embodiments, as Figure 7 shown, the lifting member 4 includes a lifting member head 401 and a lifting member base 402. Among them, the lifting member base 402 is fixed to the central area of the combustion member, the lifting member base 402 is used for clamping and fixing the lifting member head 401, and the lifting member head 401 is used for contacting the cookware 8.

[0084] When the cookware 8 is placed above the burner assembly 1, the lifting member head 401 is in the compressed state;

[0085] When the cookware 8 leaves above the burner assembly 1, the lifting member head 401 is in the extended state.

[0086] In a specific embodiment, the lifting component 4 includes two components, namely, the lifting component head 401 and the lifting component base 402. Among them, the lifting component base 402 is used to fix the moving area of the lifting component head 401, and the lifting component head 401 is used to contact the cookware 8 and switch the telescopic state under the action of the cookware 8.

[0087] In one embodiment, as Figure 6 , Figure 7 and Figure 8 shown, the lifting component head 401 includes an outer cover 4011, a spring 4012 and a guide column cylinder 4013. Among them, an annular contact piece 40111 and a guide column 40112 are arranged inside the outer cover 4011, a spring piece 40132 is arranged outside the guide column cylinder 4013, the spring piece 40132 is connected to the controller assembly 5, the spring 4012 is sleeved outside the guide column 40112, one end of the spring 4012 is connected to the guide column cylinder 4013, the other end of the spring 4012 is connected to the outer cover 4011, and the guide column 40112 is inserted into the guide column cylinder 4013 through a through hole 40131, and the through hole 40131 is arranged inside the guide column cylinder 4013.

[0088] In a specific embodiment, when the spring 4012 is in a normal state, the lifting component head 401 will be in an extended state. At this time, the annular contact piece 40111 is disconnected from the spring piece 40132. When the spring 4012 is in a compressed state, the lifting component head 401 will be in a compressed state. At this time, the annular contact piece 40111 abuts against the spring piece 40132.

[0089] When the cookware 8 is placed above the burner assembly 1, the outer cover 4011 moves downward to the first position, as Figure 7 shown, the spring 4012 is compressed, the annular contact piece 40111 abuts against the spring piece 40132, and the controller assembly 5 determines that the lifting component 4 is in a compressed state.

[0090] When the cookware 8 leaves above the burner assembly 1, the spring 4012 extends, the outer cover 4011 moves upward to the second position, as Figure 8 shown, the annular contact piece 40111 is disconnected from the spring piece 40132, and the controller assembly 5 determines that the lifting component 4 is in an extended state.

[0091] In this embodiment, by sleeving the spring 4012 outside the guide post 40112, the spring 4012 can be deformed following the movement of the outer cover 4011. When the cookware 8 leaves above the burner assembly 1, the spring 4012 no longer receives the force conducted by the outer cover 4011 and enters the state of restoring deformation, driving the outer cover 4011 to move to the second position, that is, the position where the elastic piece 40132 contacts the buffer pad 4014. When the cookware 8 is placed above the burner assembly 1, the outer cover 4011 moves to the first position under the action of the cookware 8, and the spring 4012 enters the compressed state according to the force conducted by the outer cover 4011. The spring 4012 is compressed until the elastic piece 40132 abuts against the annular contact piece 40111.

[0092] In this embodiment, by setting the simple structures of the outer cover 4011, the spring 4012 and the guide post cylinder 4013 as in the foregoing embodiment, the detection of the placement state of the cookware 8 is completed by using a mechanical structure. Under the condition of using devices with lower cost, a higher-efficiency state detection is achieved.

[0093] In a specific embodiment, the guide post cylinder 4013 is clamped by the lifting component base 402, and the position of the guide post cylinder 4013 remains unchanged all the time. Affected by the combined action of the force of the spring 4012 and the force of the cookware 8, the guide post 40112 will drive the outer cover 4011 and the annular contact piece 40111 to move up and down. Specifically, the highest position where the outer cover 4011 can move is the second position, and the lowest position where the outer cover 4011 can move is the first position. The structure of the outer cover 4011 is a downward "mountain" shape structure, and a guide post 40112 is arranged in the middle of the concave area. The guide post 40112 is embedded in the through hole 40131 of the guide post cylinder 4013, so as to ensure the stable movement direction of the outer cover 4011.

[0094] In one embodiment, as Figure 6 shown, the lifting component base 402 includes a first base 4021, a second base 4022 and a screw 4023.

[0095] The first base 4021 and the second base 4022 are used to clamp the lifting component head 401 and are fastened by the screw 4023.

[0096] In a specific embodiment, the first base 4021 and the second base 4022 are configured with protrusions and grooves that can be embedded in each other. The protrusions can be provided on the first base 4021 and the grooves on the second base 4022, or the protrusions and grooves can be respectively provided on the first base 4021, and the grooves and protrusions corresponding to the first base 4021 are provided on the second base 4022. The specific structures of the first base 4021 and the second base 4022 are not limited in this embodiment. Specifically, after the protrusions and grooves are embedded in each other, the first base 4021 and the second base 4022 can be fixed, so that the first base 4021 and the second base 4022 can clamp the guide post cylinder 4013 more stably.

[0097] In the actual application process, both the first base 4021 and the second base 4022 are configured with certain arc-shaped concave surfaces, so as to effectively clamp the guide post cylinder 4013. In a specific embodiment, a plurality of holes for setting the screws 4023 can be configured on the first base 4021 and the second base 4022. When the first base 4021 and the second base 4022 are in the clamping state, they can be further fastened by the screws 4023.

[0098] In one of the embodiments, as Figure 6 shown, the head 401 of the lifting member further includes a buffer pad 4014.

[0099] The buffer pad 4014 is arranged on the inner side of the bottom end of the outer cover 4011. When the outer cover 4011 moves upward to the second position, the elastic piece 40132 contacts the buffer pad 4014.

[0100] In a specific embodiment, a buffer pad 4014 is further arranged on the inner side of the bottom end of the outer cover 4011, that is, buffer pads 4014 are arranged on the inner side surfaces of both sides of the concave structure of the outer cover 4011. The buffer pad 4014 is used to prevent the elastic piece 40132 from colliding with the inner side of the bottom end of the outer cover 4011 when the outer cover 4011 pops up upward to the second position. On the one hand, it can effectively prevent the elastic piece 40132 from being damaged, and on the other hand, it can reduce the noise when the guide post 40112 moves.

[0101] In one embodiment, as Figure 9 shown, the guide post cylinder 4013 includes a through hole 40131 and elastic pieces 40132 arranged on the outside. A plurality of elastic pieces 40132 are arranged on the outside of the guide post cylinder 4013, and the elastic pieces 40132 are arranged around the outside of the guide post cylinder 4013.

[0102] In a specific embodiment, the elastic sheet 40132 can be arranged around the guide post cylinder 4013 to form a plane with a consistent height, so as to abut against the annular contact surface on the inner side of the outer cover 4011. The elastic sheet 40132 is a sheet material with certain elastic functions. The shape of the elastic sheet 40132 can be square, rhombic or circular, etc. The specific shape of the elastic sheet 40132 is not limited in this embodiment.

[0103] In a specific embodiment, when the elastic sheet 40132 contacts the annular contact sheet 40111, the control component can detect the state change of the lifting component 4, so as to determine the telescopic state of the lifting component 4. In the actual application process, when the elastic sheet 40132 contacts the annular contact sheet 40111, an electrical signal such as current or voltage can be generated and transmitted to the control component.

[0104] In the actual application scenario, when the elastic sheet 40132 contacts the annular contact sheet 40111, a conduction loop is formed between the circuit connection part of the elastic sheet 40132 and the controller component 5 and the circuit connection part of the environmental contact sheet 40111. The controller component 5 can receive the electrical signal transmitted from the lifting component 4, so as to determine that the lifting component 4 is in the compressed state.

[0105] In the actual application process, a certain number of resistors can be connected in series to the circuit connection part of the elastic sheet 40132 and the controller component to generate corresponding electrical signals.

[0106] In summary, this embodiment provides a gas stove. By configuring the lifting component 4 that can switch the telescopic state according to the placement state of the cookware 8, the flame combustion state of the combustion component in the gas stove can be switched with the change of the telescopic state of the lifting component 4. When the cookware 8 is placed on the burner assembly 1, the lifting component 4 enters the compressed state, and both the outer ring burner cap 201 and the central burner cap 202 of the combustion component are ignited, and the cookware 8 is heated by the outer ring flame and the central flame at the same time. When the cookware 8 is removed from the burner assembly 1, the lifting component 4 enters the extended state, the outer ring burner cap 201 of the combustion component extinguishes the outer ring flame, and the central burner cap 202 remains burning to provide the central flame. By automatically switching the flame combustion state of the combustion component, the gas consumption during the daily use of the gas stove can be effectively saved, and it is beneficial to ensure kitchen safety and avoid the occurrence of safety accidents.

[0107] In a more detailed embodiment, this embodiment provides a gas stove. When a user is using the gas stove, the cookware 8 is placed on the support frame 6 of the gas cooking top, the gas stove is lit, and the flame state of the gas stove is adjusted to the maximum. At this time, the lifting component 4 arranged in the central area of the combustion component of the gas stove is in a compressed state under the action of the cookware 8. When the lifting component 4 is in the compressed state, the annular contact piece 40111 inside the outer cover at the head of the lifting component 4 abuts against the elastic piece 40132 arranged outside the guide column cylinder 4013. The controller assembly 5 receives the state signal transmitted by the lifting component 4 and determines that the lifting component 4 is in the compressed state. The controller assembly 5 sends a control signal to the valve body assembly 3, and the valve body assembly 3 keeps the blocking piece 3031 stationary, keeps the outer ring gas passage 301 and the central gas passage 302 unblocked, and the combustion component generates an outer ring flame and a central flame through the outer ring flame on the outer ring burner cap 201 and the central burner cap 202 to heat the cookware 8.

[0108] When the user removes the cookware 8 from the support frame 6 of the gas cooking top, at this time, the lifting component 4 arranged in the central area of the combustion component of the gas stove enters the extended state due to the action of the spring 4012. When the lifting component 4 is in the extended state, the annular contact piece 40111 inside the outer cover at the head of the lifting component 4 disconnects from the elastic piece 40132 arranged outside the guide column cylinder 4013, and the elastic piece 40132 contacts the buffer pad 4014 arranged inside the bottom end of the outer cover. Since the annular contact piece 40111 disconnects from the elastic piece 40132, the state signal transmitted by the lifting component 4 received by the controller assembly 5 changes. The controller assembly 5 sends a control signal to the valve body assembly 3 to make the valve body assembly 3 push the blocking piece 3031 to close the outer ring gas passage 301. At this time, the gas in the outer ring gas passage 301 cannot be transported to the outer ring burner cap 201 of the burner component 2, and the flame on the outer ring burner cap 201 goes out. The burner component 2 only generates a central flame through the central burner cap 202.

[0109] As Figure 10 shown, a flame control method is also provided, which is applied to the controller assembly of the gas stove in the foregoing embodiment and includes:

[0110] S1001, when the cookware is placed above the burner assembly, control the valve body assembly to be fully opened so that the burner component generates a flame according to the first gas flow rate;

[0111] S1002, when the cookware leaves above the burner assembly, control the valve body assembly to be partially opened so that the burner component generates a flame according to the second gas flow rate, and the first gas flow rate is greater than the second gas flow rate.

[0112] In one of the embodiments, as Figure 11 shown, the flame control method further includes:

[0113] S1101, when the pot is placed on the burner head assembly, the outer ring gas passage and the central gas passage of the control valve body assembly are both connected, so that the outer ring flame cover and the central flame cover of the burner component both generate flames;

[0114] S1102, when the pot leaves the top of the burner assembly, the outer ring gas passage is controlled to be shut off and the central gas passage is turned on, so that the central fire cover generates flames.

[0115] Specifically, the specific implementation of the flame control method in this embodiment can refer to the specific implementation of the aforementioned device embodiment, which will not be described in detail here.

[0116] The flame control method provided in this embodiment is configured with a lifting component that can switch the telescopic state according to the placement state of the pot, so that the flame combustion state of the combustion component in the gas stove can be switched according to the change of the telescopic state of the lifting component. When the pot is placed on the burner assembly, the lifting component enters a compressed state, and the outer ring fire cover and the center fire cover of the combustion component are both ignited, and the pot is heated by the outer ring flame and the center flame at the same time. When the pot is removed from the burner assembly, the lifting component enters an extended state, the outer ring fire cover of the combustion component extinguishes the outer ring flame, and the center fire cover keeps burning to provide a center flame. By automatically switching the flame combustion state of the combustion component, the gas loss in the daily use of the gas stove can be effectively saved, and it is conducive to ensuring kitchen safety and avoiding the occurrence of safety accidents.
