Description

Technical Field

[0001] This application relates to the field of stove technology, and in particular to a gas stove and its control method. Background Technology

[0002] A gas stove is a kitchen appliance that uses combustible gases such as petroleum gas, manufactured gas, and natural gas as fuel for heating.

[0003] In related technologies, a gas stove includes a housing, a burner head, and an energy-concentrating plate. The housing has an installation port, the burner head passes through the installation port, and the energy-concentrating plate is mounted on the housing and surrounds the burner head. The burner head is used to burn combustible gas, and the energy-concentrating plate is used to limit the heat generated during the combustion of combustible gas from dissipating into the surrounding environment.

[0004] However, a significant portion of the heat generated by the combustion of combustible gas in gas stoves in related technologies is still lost to the surrounding environment through the energy-concentrating plate, resulting in low thermal efficiency of the gas stove. Summary of the Invention

[0005] Embodiments of this application provide a gas stove and its control method to solve the problem of low thermal efficiency of gas stoves in related technologies.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a gas stove, which includes a housing, a burner, an energy-concentrating plate, a fan, a temperature sensor, and a controller.

[0008] The casing has an installation port, through which the burner head passes and is used to burn combustible gas. A concentrating plate is located on the side of the casing with the installation port and surrounds the burner head. The concentrating plate has a heat insulation cavity and is equipped with an air inlet and an air outlet communicating with the heat insulation cavity. The air inlet is located on the side of the concentrating plate away from the burner head, and the air outlet is located on the side of the concentrating plate closer to the burner head. A fan is used to draw air into the heat insulation cavity through the air inlet and exhaust it through the air outlet. A temperature sensor is used to detect the temperature inside the heat insulation cavity. A controller is connected to the fan and the temperature sensor, and the controller is configured to: acquire the temperature inside the heat insulation cavity in real time. If the temperature inside the heat insulation cavity is greater than or equal to a first preset temperature, the fan is controlled to operate. After the fan has started operating, if the temperature inside the heat insulation cavity is less than a second preset temperature, the fan is controlled to stop operating. The second preset temperature is less than the first preset temperature.

[0009] It is understandable that setting up a heat insulation cavity on the energy-concentrating plate can reduce the heat conduction efficiency of the energy-concentrating plate, thereby reducing the heat generated during the combustion of combustible gas from being lost to the surrounding environment through the energy-concentrating plate, and thus improving the thermal efficiency of the gas stove.

[0010] Furthermore, during the operation of the gas stove, the air inside the insulation chamber is heated to a high temperature. At this time, the controller can control the fan to operate, thereby driving the high-temperature air inside the insulation chamber through the air outlet to the burner, thus heating cooking utensils and other items. This allows for the recovery and utilization of heat within the insulation chamber, thereby improving the thermal efficiency of the gas stove. Additionally, the air exhausted from the air outlet also replenishes the air around the burner, which helps to ensure more complete combustion of combustible gases, thus improving the thermal efficiency of the gas stove.

[0011] In some embodiments, the gas stove further includes a control valve having an outlet and an inlet connected to each other. The outlet is connected to the burner head, and the inlet is used to connect to the gas supply line. The control valve is connected to a controller, which is further configured to close the control valve if the temperature inside the insulation chamber is greater than or equal to a third preset temperature. The third preset temperature is greater than a first preset temperature.

[0012] In some embodiments, the gas stove further includes a reminder device for issuing a notification message. The reminder device is connected to a controller, which is further configured to issue a notification message if the temperature inside the insulation cavity is greater than or equal to a third preset temperature.

[0013] In some embodiments, an insulation cavity is arranged around the burner head. There are multiple air outlets, and these outlets are spaced apart circumferentially around the burner head.

[0014] In some embodiments, the energy-concentrating plate includes a main body and a plurality of support portions connected to the main body. The main body is arranged around the burner head, and an insulation cavity, an air inlet, and an air outlet are disposed on the main body. The plurality of support portions are spaced apart circumferentially along the burner head and are used to support the cooking appliance. Parts of the support portions are located within the insulation cavity, and the portions of the plurality of support portions within the insulation cavity divide the insulation cavity into a plurality of sub-cavities, with the air inlet communicating with one of the sub-cavities. At least a portion of the support portions is provided with ventilation holes for communicating the plurality of sub-cavities with the air inlet.

[0015] In some embodiments, the controller is located within the mounting cavity, and the fan is located within the insulation cavity. A first wiring hole is also provided on the housing. The gas stove also includes a first cable, which passes through the air inlet and the first wiring hole, and the fan is connected to the controller via the first cable.

[0016] In some embodiments, the gas stove further includes a liquid collection tray, which comprises a tray body and a baffle. The tray body is disposed between the energy-concentrating plate and the housing, and has a clearance opening and a second wiring hole. The burner head passes through the clearance opening, and the first cable passes through the second wiring hole. The baffle is connected to the tray body and is located on the side of the tray body closer to the energy-concentrating plate. The baffle is arranged around the second wiring hole. The energy-concentrating plate also includes a blocking portion, which is connected to the main body and located on the side of the main body closer to the tray body. The blocking portion is arranged around the air inlet and the baffle, and the blocking portion contacts the surface of the baffle opposite to the second wiring hole.

[0017] In some embodiments, the gas stove further includes an electric heater, which is at least partially located within the insulation cavity and is used to heat the air within the insulation cavity.

[0018] Secondly, embodiments of this application provide a control method for a gas stove, used to control a gas stove according to any of the embodiments in the first aspect described above. The control method includes: acquiring the temperature inside the insulation cavity in real time; if the temperature inside the insulation cavity is greater than or equal to a first preset temperature, controlling a fan to operate; and after the fan has started operating, if the temperature inside the insulation cavity is less than a second preset temperature, controlling the fan to stop operating. The second preset temperature is less than the first preset temperature.

[0019] In some embodiments, the control method further includes: if the temperature inside the insulation cavity is greater than or equal to a third preset temperature, controlling the control valve to close. The third preset temperature is greater than the first preset temperature.

[0020] Thirdly, embodiments of this application provide a controller, including: one or more processors; one or more memories; wherein the one or more memories are used to store computer program code, the computer program code including computer instructions, and when the one or more processors execute the computer instructions, the controller executes any of the gas stove control methods provided in the second aspect.

[0021] Fourthly, embodiments of this application provide a computer-readable storage medium including computer instructions that, when executed on a computer, cause the computer to perform any of the gas stove control methods provided in the second aspect.

[0022] Fifthly, embodiments of the present invention provide a computer program product that can be directly loaded into a memory and contains software code. After being loaded and executed by a computer, the computer program product can realize any of the gas stove control methods provided in the second aspect.

[0023] It should be noted that the aforementioned computer instructions may be stored, in whole or in part, on a computer-readable storage medium. This computer-readable storage medium may be packaged together with the controller's processor, or it may be packaged separately from the controller's processor; this application does not impose any limitations on this.

Detailed Implementation

[0044] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0046] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] It should be noted that in practical applications, due to limitations in equipment precision or installation errors, achieving absolute parallelism or perpendicularity is difficult. The descriptions of "perpendicular," "parallel," or "in the same direction" in this application are not absolute limitations, but rather indicate that a vertical or parallel structural arrangement can be achieved within a preset error range, achieving the corresponding preset effect. This maximizes the technical effect of the defined features and makes the corresponding technical solution easy to implement, possessing high feasibility. For example, "perpendicular" includes absolute perpendicularity and near-perpendicularity, where the acceptable deviation range for near-perpendicularity can be, for example, within 5°. "Parallel" includes absolute parallelism and near-parallelism, where the acceptable deviation range for near-parallelism can also be, for example, within 5°. "In the same direction" includes absolute same direction and near-same direction, where the acceptable deviation range for near-same direction can also be, for example, within 5°.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0050] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] Gas stoves are common cooking appliances in modern kitchens. They mainly produce flames by burning combustible gases such as liquefied petroleum gas, manufactured gas, and natural gas to provide heat for cooking activities such as stir-frying, boiling water, and steaming. With the improvement of living standards, gas stoves have become widely popular and are a common kitchen appliance in homes.

[0052] In related technologies, a gas stove includes a shell, a burner head, and an energy-concentrating plate. The shell has an installation port, the burner head passes through the installation port, and the energy-concentrating plate is mounted on the shell and surrounds the burner head. The burner head is used to burn combustible gas, and the energy-concentrating plate is used to limit the heat generated during combustion of the combustible gas from dissipating into the surrounding environment. However, during use, some of the heat generated during the combustion of the combustible gas in the aforementioned gas stove is transferred to the energy-concentrating plate, and then dissipated into the surrounding environment through the energy-concentrating plate, resulting in low thermal efficiency of the gas stove.

[0053] Based on this, see Figure 1 , Figure 1 This is a structural diagram of a gas stove 100 provided in an embodiment of this application. This embodiment of the application provides a gas stove 100 to address the problem of low thermal efficiency in gas stoves in related technologies.

[0054] The gas stove 100 can be a countertop stove, a built-in stove, or a combination of both. The specific type can be selected based on the actual situation, and this application does not impose any specific restrictions.

[0055] The gas stove 100 includes a housing 1, which is usually placed or installed on a stovetop to provide stable support for the gas stove 100, thereby providing stable support for cooking appliances such as kettles and pots.

[0056] See Figure 2 , Figure 2 This is a cross-sectional view of a housing 1 provided in an embodiment of this application. The housing 1 has a mounting 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 mounting cavity 11. In this way, the risk of damage to the gas stove 100 can be reduced, which helps to extend the service life of the gas stove 100.

[0057] For example, such as Figure 2 As shown, the housing 1 includes a bottom shell 12 and a front panel 13. The bottom shell 12 forms a mounting cavity 11 with an opening 121. The front panel 13 is disposed on the side of the opening 121 of the bottom shell 12 and covers the opening 121. At this time, the front panel 13 and the bottom shell 12 form a closed mounting cavity 11.

[0058] In some embodiments, the housing 1 is further provided with a mounting port 131, which communicates with the mounting cavity 11. For example, the mounting port 131 is provided on the panel 13 and communicates with the mounting cavity 11.

[0059] The number of mounting ports 131 can be one or more, and the specific number can be selected according to the actual situation. This application does not make a specific limitation on this.

[0060] The gas stove 100 also includes a burner 2, which is used to burn combustible gas. That is, combustible gas can be delivered to the burner 2 through a pipeline and then burned at the burner 2 to heat the cooking appliances. The burner 2 can be installed in the mounting port 131.

[0061] It is understood that the number of burners 2 can be one or more, and the specific number can be selected according to the actual situation. This application does not make any specific restrictions on this.

[0062] For example, such as Figure 1 As shown, there are multiple burner heads 2 and mounting ports 131, spaced apart, with one burner head 2 located within one mounting port 131. This arrangement allows different cooking appliances to be heated simultaneously by different burner heads 2, thus improving cooking efficiency and enhancing the user experience.

[0063] It should be noted that, as Figure 3 As shown, Figure 3 This is a structural diagram of a control valve 3 provided in an embodiment of this application. The gas stove 100 may further include the control valve 3, which has an outlet 31 and an inlet 32 ​​that are interconnected. The outlet 31 is connected to the burner head 2 (e.g., Figure 1 As shown, inlet 32 ​​is used to connect to the gas supply line. That is to say, the burner head 2 is connected to the gas supply line through control valve 3.

[0064] Among them, control valve 3 can be a solenoid valve.

[0065] Understandably, when control valve 3 is open, combustible gas in the gas supply line can enter the burner head 2 through control valve 3 and then burn there to heat the cooking appliance. When control valve 3 is closed, it prevents combustible gas in the gas supply line from entering the burner head 2, thereby extinguishing the flame at the burner head 2 and stopping the heating of the cooking appliance.

[0066] In some embodiments, see Figure 4 , Figure 4 This is a structural diagram of an energy-concentrating plate 4 provided in an embodiment of this application. The gas stove 100 also includes an energy-concentrating plate 4, which is disposed on the side of the housing 1 where the mounting port 131 is provided, and the energy-concentrating plate 4 surrounds the burner head 2 (e.g., Figure 1 (As shown) Weekly settings.

[0067] In this way, during the operation of the gas stove 100, the energy-concentrating plate 4 can prevent the hot air around the burner 2 from spreading into the surrounding environment, thereby reducing heat loss and improving the thermal efficiency of the gas stove 100.

[0068] The energy-concentrating disk 4 can be placed on the housing 1, or it can be connected to the housing 1 by screws, snap-fit, or other means (e.g., Figure 1 The connection shown can be selected according to the actual situation, and this application does not make specific limitations on it.

[0069] To further reduce heat loss, such as Figure 5 As shown, Figure 5 This is a cross-sectional view of an energy-concentrating plate 4 provided in an embodiment of this application. A heat insulation cavity 41 can also be provided on the energy-concentrating plate 4. It is understood that providing a heat insulation cavity 41 on the energy-concentrating plate 4 can reduce the heat conduction efficiency of the energy-concentrating plate 4, thereby reducing the heat generated during the combustion of combustible gas from being dissipated into the surrounding environment through the energy-concentrating plate 4, and thus improving the thermal efficiency of the gas stove 100.

[0070] The heat insulation cavity 41 can be arranged around the entire burner head 2 or around a part of the burner head 2. The specific arrangement can be selected according to the actual situation, and this application does not make any specific limitation on this.

[0071] The following example, using the example of the heat insulation cavity 41 surrounding the furnace head 2, illustrates some embodiments of this application.

[0072] In some embodiments, see Figure 6 , Figure 6 This application provides a structural diagram of an energy-concentrating disk 4 according to an embodiment. The energy-concentrating disk 4 is provided with a heat insulation cavity 41 (e.g., Figure 5 (As shown) The air inlet 42 and air outlet 43 are connected. The air inlet 42 is located on the energy-concentrating plate 4 away from the burner head 2 (as shown). Figure 1 As shown in the figure, the air outlet 43 is located on the side of the energy-concentrating plate 4 near the burner head 2.

[0073] The air outlet 43, near the burner head 2, can be tilted away from the housing 1. This creates a louver structure at the air outlet 43, which helps reduce the amount of liquid overflowing from the cooking pot entering the heat insulation cavity 41 through the air outlet 43.

[0074] It should be noted that, see Figure 7 , Figure 7 A cross-sectional view of an energy-concentrating plate 4 and a fan 5 provided for an embodiment of this application. The gas stove 100 may also include a fan 5, which drives air from the air inlet 42 (e.g., Figure 6(As shown) It enters the heat insulation cavity 41 and is discharged through the air outlet 43.

[0075] The fan 5 can be installed inside the insulation cavity 41 to drive the air inside the insulation cavity 41 from the air inlet 42 to the air outlet 43, thereby driving the air to enter the insulation cavity 41 from the air inlet 42 and exit through the air outlet 43. Alternatively, the fan 5 can be installed outside the insulation cavity 41 and connected to the air inlet 42 through an air duct, driving the air to enter the insulation cavity 41 from the air inlet 42 and exit through the air outlet 43.

[0076] Understandably, during the operation of the gas stove 100, the air inside the insulation chamber 41 is heated to a high temperature. At this time, controlling the operation of the fan 5 drives the high-temperature air inside the insulation chamber 41 to flow through the air outlet 43 to the burner 2, thereby heating cooking utensils and other items. This allows for the recovery and utilization of heat within the insulation chamber 41, thus improving the thermal efficiency of the gas stove 100. Furthermore, the air exhausted from the air outlet 43 also replenishes the air around the burner 2, which helps to ensure more complete combustion of combustible gases, thereby improving the thermal efficiency of the gas stove 100.

[0077] It should be noted that the number of air outlets 43 can be one or more, and the specific number can be selected according to the actual situation. This application does not make a specific limitation on this.

[0078] Among them, such as Figure 6 As shown, when there are multiple air outlets 43, the multiple air outlets 43 can be arranged along the burner head 2 (e.g., Figure 1 The circumferential spacing (as shown) allows the hot air in the insulation cavity 41 to flow more evenly from the periphery of the burner head 2 to the burner head 2. This not only makes the cooking appliance heated more evenly, but also allows the combustible gas to come into full contact with the hot air, thus enabling complete combustion.

[0079] To achieve automatic control of fan 5, see [link to relevant documentation]. Figure 8 , Figure 8 This is a hardware configuration block diagram of a gas stove 100 provided in an embodiment of this application. The gas stove 100 may further include a temperature sensor 6 and a controller 7. The temperature sensor 6 is used to detect the temperature of the insulation cavity 41 (e.g., Figure 7 The temperature inside (as shown), controller 7 and fan 5 (as shown) Figure 7 (as shown) and connected to temperature sensor 6.

[0080] The controller 7 can obtain the temperature inside the insulation cavity 41 through the temperature sensor 6, and control the fan 5 to start or stop operating based on the temperature inside the insulation cavity 41. In this way, automatic control of the fan 5 can be achieved, which helps to improve the user experience.

[0081] It should be noted that the temperature sensor 6 can be entirely or partially installed within the insulation cavity 41, for example, the temperature sensor 6 can be installed inside the air inlet 42. The specific choice can be made according to the actual situation, and this application does not impose any specific limitations on this.

[0082] Among them, see Figure 9 , Figure 9 This is a structural diagram of a temperature sensor 6 and a second cable 9 provided in an embodiment of this application. The temperature sensor 6 can be a semiconductor thermistor with a negative temperature coefficient, whose resistance decreases as its temperature rises and increases as its temperature falls, causing a change in the voltage across the resistor due to the change in resistance.

[0083] It is understood that the temperature sensor 6 and the fan 5 can be connected to the controller 7 either wirelessly or via cable, depending on the actual situation. This application does not make any specific restrictions on this.

[0084] It should be noted that, as Figure 8 As shown, controller 7 refers to a device that can generate operation control signals based on instruction operation codes and timing signals, and instruct the gas stove 100 to execute control commands.

[0085] For example, the controller 7 can be a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof.

[0086] It is understood that the controller 7 may also be other devices with processing functions, such as circuits, devices or software modules, and the embodiments of this application do not impose any limitations on this.

[0087] In some embodiments, see Figure 2 and Figure 10 , Figure 10 This application provides a structural diagram of a fan 5 and a first cable 8 according to an embodiment. The gas stove 100 also includes the first cable 8, through which the fan 5 is connected to the controller 7 (e.g., Figure 8 (As shown) connection.

[0088] The controller 7 can be installed either inside the mounting cavity 11 of the housing 1 or outside the housing 1. The specific choice can be made according to the actual situation, and this application does not make any specific limitation.

[0089] For example, the controller 7 is located in the mounting cavity 11, and the fan 5 is located in the heat insulation cavity 41. In this case, the housing 1 is also provided with a first wiring hole, and a first cable 8 passes through the air inlet 42 and the first wiring hole, and the first cable 8 is connected to the controller 7 and the fan 5.

[0090] Additionally, see Figure 9 The gas stove 100 may also include a second cable 9, through which the temperature sensor 6 is connected to the controller 7 (e.g., Figure 8 (As shown) connection.

[0091] For example, the controller 7 is located inside the mounting cavity 11, and the temperature sensor 6 is located inside the heat insulation cavity 41. Furthermore, the second cable 9 passes through the air inlet 42 and the first wiring hole, and the second cable 9 is connected to the controller 7 and the temperature sensor 6.

[0092] It should be noted that, see Figure 8 The controller 7 can also be connected to the control valve 3, and the controller 7 can control the control valve 3 to open or close according to the temperature inside the insulation cavity 41.

[0093] For example, if the moisture in the cooking appliance evaporates completely and dry burning occurs, the temperature inside the insulation cavity 41 will rise sharply. At this time, the controller 7 can control the control valve 3 to close, thereby stopping the supply of combustible gas to the burner 2. In this way, the gas stove 100 can achieve the anti-dry burning function, which helps to improve the safety of the gas stove 100.

[0094] Additionally, see Figure 8 The gas stove 100 may also include a reminder device 10, which is used to issue a reminder message.

[0095] The reminder device 10 is connected to the controller 7, and the controller 7 can control the reminder device 10 to issue reminder information according to the temperature inside the heat insulation cavity 41.

[0096] For example, when a cooking appliance is dry-burning, the temperature inside the insulation cavity 41 will rise sharply. At this time, the controller 7 can control the reminder device 10 to issue a prompt message, thereby reminding the user that the cooking appliance has dry-burned.

[0097] It is understood that the reminder device 10 can be an indicator light, a sound player, etc., and the specific device can be selected according to the actual situation. This application does not make any specific limitations on this.

[0098] In some embodiments, see Figure 8 The gas stove 100 also includes an electric heater 20, which is at least partially located in the heat insulation chamber 41 (e.g., Figure 7 (as shown) and is used to heat the air inside the insulation cavity 41.

[0099] In this configuration, the air inside the insulation chamber 41 can be heated by the electric heater 20, and then the heated air can be carried out of the insulation chamber 41 through the air outlet 43 by the fan 5, thereby heating the cooking utensils.

[0100] It should be noted that the cooking appliance can be heated simultaneously using both the flame on burner 2 and the air heated by electric heater 20 to improve heating efficiency. Alternatively, the cooking appliance can be heated solely using the air heated by electric heater 20 to enable the gas stove 100 to maintain its temperature.

[0101] Among them, such as Figure 8 As shown, the electric heater 20 can also be connected to the controller 7, in which case the controller 7 can control the electric heater 20 to turn on or off.

[0102] In some embodiments, see Figure 11 , Figure 11 A cross-sectional view of a heat-concentrating plate 4 provided in an embodiment of this application. The heat-concentrating plate 4 includes a main body 44 and a plurality of supporting parts 45, the main body 44 surrounding the burner head 2 (e.g., Figure 1 As shown, multiple support parts 45 are arranged around the burner head 2 and connected to the main body 44. The multiple support parts 45 are spaced apart along the circumference of the burner head 2, for example, the multiple support parts 45 are evenly distributed along the circumference of the burner head 2. Among them, the heat insulation cavity 41 is provided on the main body 44, and the multiple support parts 45 are used to support cooking utensils.

[0103] To support the cooking appliance, the support portion 45 can be configured to be at least partially located on the side of the main body 44 away from the housing 1. In this case, the cooking appliance can be supported by the end of the support portion 45 away from the housing 1. It is understood that the support portion 45 can also be configured to be at least partially located on the side of the main body 44 near the burner 2. In this case, the cooking appliance can be supported by the end of the support portion 45 near the burner 2.

[0104] It should be noted that, as Figure 11 As shown, the support portion 45 may be partially located within the heat insulation cavity 41, and the portion of the multiple support portions 45 located within the heat insulation cavity 41 divides the heat insulation cavity 41 into multiple sub-cavities.

[0105] In this configuration, the air inlet 42 can communicate with a sub-cavity. At least a portion of the support 45 is provided with ventilation holes 451, which allow multiple sub-cavities to communicate with the air inlet 42. For example, two adjacent sub-cavities can be connected through the ventilation holes 451, thereby enabling multiple sub-cavities to communicate with each other and thus achieving communication between multiple sub-cavities and the air inlet 42.

[0106] For example, the support 45 includes a first leg and a plurality of second legs, with a ventilation hole 451 provided on the second legs.

[0107] In some embodiments, see Figure 11 The main body 44 is provided with a plurality of mounting holes 441 communicating with the heat insulation cavity 41, and the mounting holes 441 are along the energy-concentrating disk 4 and the shell 1 (e.g. Figure 1 The arrangement direction (as shown) extends through the main body 44.

[0108] Based on this, a support part 45 is correspondingly inserted into a mounting hole 441, and the two ends of the support part 45 extend out of the mounting hole 441 in the arrangement direction of the energy-concentrating disk 4 and the housing 1.

[0109] With this configuration, the support portion 45 can be connected to the housing 1 through the mounting hole 441, allowing the housing 1 to directly support the cooking appliance via the support portion 45. This reduces the risk of deformation of the main body 44, which has the heat insulation cavity 41.

[0110] In some embodiments, see Figure 12 , Figure 12 This is a structural diagram of an energy-concentrating plate 4 and a liquid-collecting plate 30 provided in an embodiment of this application. The gas stove 100 also includes a liquid-collecting plate 30, which is disposed between the energy-concentrating plate 4 and the housing 1 (e.g., Figure 1 (as shown) and the liquid tray 30 is in contact with the energy-concentrating tray 4 and the shell 1.

[0111] The liquid-filling tray 30 is provided with an avoidance opening 301, and the burner head 2 (such as...) Figure 1 As shown, the liquid tray 30 is inserted into the relief opening 301 and is used to collect liquids that spill out of the cooking appliance.

[0112] It should be noted that, see Figure 13 , Figure 13 This is a structural diagram of a liquid-collecting tray 30 provided in an embodiment of this application. The liquid-collecting tray 30 may also be provided with a second wire-passing hole 302, for connection to the fan 5 (e.g., ...). Figure 10 The first cable 8 (as shown) is connected to the first cable. Figure 10 (As shown) can pass through the air inlet 42 in sequence (as shown) Figure 6 As shown), the second wire hole 302 and the first wire hole are connected to the controller 7.

[0113] The same, such as Figure 9 and Figure 13 As shown, the second cable 9, which is connected to the temperature sensor 6, can pass through the air inlet 42 in sequence (e.g., Figure 6 As shown), the second wire hole 302 and the first wire hole are connected to the controller 7.

[0114] For example, such as Figure 13 As shown, the liquid-holding tray 30 includes a tray body 303 and a baffle 304 connected to each other. The tray body 303 is disposed on the energy-concentrating tray 4 (e.g., Figure 12 (as shown) and housing 1 (as shown) Figure 1 As shown, the baffle 304 is located on the side of the disc body 303 close to the energy-concentrating disc 4.

[0115] The clearance opening 301 and the second wire-passing hole 302 are provided on the disc body 303, and the baffle 304 is arranged around the second wire-passing hole 302. In this way, the baffle 304 can prevent the liquid in the liquid-filled tray 30 from flowing to the second wire-passing hole 302, thereby reducing the risk that the liquid in the liquid-filled tray 30 will flow into the mounting cavity 11 through the second wire-passing hole 302 and the first wire-passing hole in sequence.

[0116] It should be noted that, as Figure 12 and Figure 13 As shown, the energy-concentrating disk 4 may further include a blocking part 46, which is connected to the main body 44 and located on the side of the main body 44 near the disk body 303. The blocking part 46 surrounds the air inlet 42 (e.g., Figure 6 As shown, the baffle 304 is arranged around the perimeter, and the blocking part 46 contacts the surface of the baffle 304 away from the second wire hole 302.

[0117] In this configuration, the blocking part 46 and the baffle 304 can seal the gap between the air inlet 42 and the second wire hole 302, thereby further reducing the risk of liquid in the liquid tray 30 entering the mounting cavity 11.

[0118] In some embodiments, see Figure 14 , Figure 14 This is a structural diagram of an energy-concentrating plate 4 and a mounting bracket 40 provided in an embodiment of this application. The gas stove 100 also includes a mounting bracket 40, which is located at the air inlet 42 and is detachably connected to the blocking part 46. The mounting bracket 40 is provided with a through hole 401, through which air can enter the heat insulation cavity 41.

[0119] It is understandable that there can be one or more through holes 401, and the first cable 8 and the second cable 9 can also be inserted into the through holes 401.

[0120] It should be noted that, as Figure 15 As shown, Figure 15 This is a structural diagram of a fan 5, a temperature sensor 6, a first cable 8, a second cable 9, and a mounting bracket 40 provided in an embodiment of this application. The fan 5 can be mounted on the mounting bracket 40, and the temperature sensor 6 can also be mounted on the mounting bracket 40. This facilitates the removal of the mounting bracket 40 from the blocking part 46 for maintenance or replacement of the fan 5 and the temperature sensor 6 on the mounting bracket 40.

[0121] This application also provides a control method for a gas stove, which can be applied to the controller in the aforementioned gas stove. See also Figure 16 , Figure 16 This is a schematic diagram illustrating the working process of a gas stove 100 according to an embodiment of this application. The control method may include the following steps:

[0122] S101. Real-time acquisition of the temperature inside the insulation cavity.

[0123] When a user turns on the gas stove to heat cooking appliances, the controller can obtain the temperature inside the insulation cavity in real time through a temperature sensor to monitor the heating status.

[0124] S102. If the temperature inside the insulation cavity is greater than or equal to the first preset temperature, control the fan to run.

[0125] When the temperature inside the insulation chamber reaches the first preset temperature as determined by the controller, the controller will control the fan to run, so that the air inside the insulation chamber is blown towards the furnace head through the air outlet.

[0126] This not only enables the recovery and utilization of heat within the insulation cavity but also allows for the replenishment of secondary air, thereby improving the thermal efficiency of the gas stove.

[0127] The first preset temperature can be set according to the actual situation, and this application does not make specific limitations on it.

[0128] S103. If the temperature inside the insulation cavity is lower than the second preset temperature, control the fan to stop running.

[0129] The second preset temperature is lower than the first preset temperature.

[0130] It is understandable that the second preset temperature can also be set according to the actual situation, and this application does not make specific limitations on this.

[0131] After the fan starts running, if the temperature inside the insulation cavity obtained by the controller is lower than the second preset temperature, the controller will control the fan to stop running.

[0132] Understandably, after the gas stove stops heating the cooking appliances, the temperature inside the insulation cavity will gradually decrease. When the temperature drops below the second preset temperature, the fan will stop running, thus achieving energy saving.

[0133] In some embodiments, the control method may further include the following steps:

[0134] S104. If the temperature inside the insulation cavity is greater than or equal to the third preset temperature, the control valve will be closed.

[0135] The third preset temperature is greater than the first preset temperature.

[0136] It is understandable that the third preset temperature can also be set according to the actual situation, and this application does not make specific limitations on it.

[0137] When the user turns on the gas stove to heat the cooking appliances, when the temperature inside the heat insulation cavity reaches the third preset temperature as determined by the controller, the controller will close the control valve to stop supplying combustible gas to the burner.

[0138] It is understandable that if dry burning occurs during the heating of cooking appliances using a gas stove, abnormally high temperatures will appear inside the heat insulation cavity. At this time, closing the control valve can cut off the connection between the burner and the gas supply line, thereby extinguishing the flame on the burner and reducing the risk of safety accidents.

[0139] It should be noted that while controlling the control valve to close, the reminder device can also be controlled to issue a warning message, thereby alerting the user that dry burning has occurred, so that the user can eliminate the safety hazard in time.
