Description

Technical Field

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

[0002] For aesthetic and easy-to-clean purposes, existing gas stoves generally use glass panels. However, during the use of gas stoves, the glass panel absorbs heat released from the burner, resulting in a higher temperature in the area near the burner and a lower temperature in the area away from the burner. This uneven temperature distribution across the entire glass panel can easily lead to thermal breakage of the glass. Summary of the Invention

[0003] One objective of this invention is to provide a gas stove that can select internal or external circulation to cool the glass panel according to the actual needs of the glass panel, thereby avoiding uneven temperature distribution and cracking of the panel.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Gas stoves, including:

[0006] A glass panel having at least two clearance holes, each clearance hole housing a burner;

[0007] The cooling channel includes at least two cooling sections, each of which surrounds one of the clearance holes;

[0008] The liquid supply mechanism includes a cooling medium container and a drive assembly. The two ends of the cooling channel can be selectively connected to each other or to the cooling medium container respectively. The drive assembly can drive the cooling medium to circulate within the cooling channel or between the cooling channel and the cooling medium container.

[0009] As an optional solution, the gas stove also includes a temperature sensor, with one temperature sensor corresponding to each of the clearance holes, and each of the temperature sensors is electrically connected to the drive assembly.

[0010] As an optional solution, the liquid supply mechanism further includes:

[0011] A first connecting pipe, the two ends of which are respectively connected to the two ends of the cooling channel;

[0012] The second connecting pipe connects the first end of the cooling channel to the cooling medium container;

[0013] The third connecting pipe connects the second end of the cooling channel to the cooling medium container;

[0014] A valve assembly that enables the cooling passage to communicate with the first connecting pipe or to communicate with the cooling medium container.

[0015] As an optional embodiment, the valve assembly includes a first shut-off valve and a second shut-off valve, wherein the first shut-off valve is disposed on the first connecting pipe, and the second shut-off valve is disposed on the second connecting pipe or the third connecting pipe; or

[0016] The valve assembly includes a two-position three-way valve, the first end of which is connected to the cooling channel, the second end of which is connected to the first connecting pipe, and the third end of which is connected to the second or third connecting pipe.

[0017] As an optional solution, the drive assembly includes a first drive pump and a second drive pump, wherein the first drive pump is disposed on the first connecting pipe, and the second drive pump is disposed on the second connecting pipe or the third connecting pipe; or

[0018] The drive assembly includes a drive pump, which is disposed on the cooling channel.

[0019] As an alternative, a cooling groove is formed around the clearance hole on the lower side of the glass panel, and the gas stove also includes an explosion-proof layer, which is attached to the lower side of the glass panel and forms the cooling section with the cooling groove.

[0020] As an alternative, the cooling section is constructed in a spiral shape, and the cooling section is concentrically arranged with the corresponding clearance hole.

[0021] As an alternative, the cross-sectional area of ​​the cooling section gradually decreases from the innermost ring to the outermost ring; and / or

[0022] Along the radial direction of the clearance hole and from the inside out, the distance between two adjacent rings of the cooling section gradually increases.

[0023] Another objective of this invention is to provide a control method for a gas stove that can select internal or external circulation to cool the glass panel based on the detected temperature of the glass panel, thereby minimizing energy loss and preventing uneven temperature distribution that could lead to breakage.

[0024] To achieve this objective, the present invention adopts the following technical solution:

[0025] A method for controlling a gas stove, using the aforementioned gas stove, the method comprising:

[0026] S10, obtain the screening temperature T;

[0027] S11, determine whether the screening temperature T is greater than or equal to the first preset temperature T1. If not, return to step S10; if yes, proceed to step S12.

[0028] S12; Determine whether the screening temperature T is greater than or equal to the second preset temperature T3. If not, drive the cooling medium to circulate internally in the cooling channel. If yes, drive the cooling medium to circulate externally between the cooling channel and the cooling medium container.

[0029] As an optional approach, in step S10, the operating status of all burners is also obtained. Then, it is determined whether all burners are in combustion state. If not, proceed to step S11. If yes, proceed to step S21: determine whether the screening temperature T is greater than or equal to the first preset temperature T1. If not, return to step S10. If yes, drive the cooling medium to circulate externally between the cooling channel and the cooling medium container.

[0030] As an optional approach, the screening temperature T can be obtained by acquiring the detection temperature of the glass panel at each burner, and taking the maximum value among all the detection temperatures.

[0031] As an optional solution, after driving the cooling medium to perform internal or external circulation, return to step S10. Furthermore, when it is determined that the screening temperature T is less than the first preset temperature T1, stop driving the cooling medium in the cold zone before returning to step S10.

[0032] The beneficial effects of this invention are:

[0033] In this invention, when the burner is operating and the temperature of the glass panel surrounding the burner rises, the liquid supply mechanism can drive the cooling medium to remove heat from the area around the clearance holes of the glass panel, preventing the temperature in that area from rising too high. This prevents the glass panel from cracking due to excessive temperature differences between different areas, thus extending the service life of the gas stove. Furthermore, when the temperature of the area near the burner is slightly high but not excessively high (i.e., when the cooling requirement is low), the cooling medium can circulate internally. Since internal circulation results in a slow cooling rate and a small cooling effect, it avoids removing too much heat and reducing the thermal efficiency of the gas stove. When the temperature of the area near the burner is very high (i.e., when the cooling requirement is high), the cooling medium in the cold zone circulates externally, rapidly cooling the area near the burner and preventing the glass panel from cracking due to excessive temperature differences.

[0034] The control method of this invention for a gas stove indicates that when the temperature of the area near the burner of the glass panel is greater than or equal to T1 and less than T2, it means that the current cooling demand of the glass panel is low. At this time, the cooling medium is circulated internally to prevent the glass panel from cracking due to excessive temperature difference and to prevent the cooling medium from carrying away too much heat, which would reduce the thermal efficiency of the gas stove. When the temperature of the area near the burner of the glass panel is greater than or equal to T2, it means that the current cooling demand of the glass panel is high. At this time, the cooling medium is circulated externally to quickly cool the area near the burner of the glass panel and prevent the glass panel from cracking due to excessive temperature difference.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention and not the entire structure.

[0057] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0058] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0060] This embodiment provides a gas stove, such as Figures 1-2 As shown, the gas stove includes a bracket 90, a glass panel 10, a burner 60, and a gas supply assembly. The glass panel 10 covers the upper side of the bracket 90 to improve the aesthetics of the gas stove. Both the burner 60 and the gas supply assembly are mounted on the bracket 90. The glass panel 10 has a clearance hole 11 to allow the burner 60 to be mounted, ensuring that at least part of the burner 60 is exposed on the upper side of the glass panel 10. The gas supply assembly supplies gas to the burner 60, which burns the gas to produce a flame.

[0061] like Figure 1 As shown, the gas stove also includes a drip tray 80, which is located on the upper side of the glass panel 10 and surrounds the burner 60. The drip tray 80 can block the clearance hole 11. The drip tray 80 is used to collect spills generated during cooking, preventing spills from flowing into the gas stove. The gas stove also includes a pot rack 70, which is supported on the drip tray 80 and surrounds the burner 60. The pot rack 70 is used to support pots.

[0062] In this embodiment, the gas stove includes two burners 60, so two clearance holes 11 are correspondingly provided on the glass panel 10, and each burner 60 is provided with a water tray 80 and a pot rack 70. In other embodiments, the specific number of burners 60 may be three, four or more.

[0063] During the operation of the burner 60, the glass panel 10 absorbs the heat released from the burner 60, resulting in a higher temperature in the area of ​​the glass panel 10 close to the burner 60 and a lower temperature in the area far from the burner 60. The uneven temperature distribution of the entire glass panel 10 makes it easy for the glass to break.

[0064] In this regard, such as Figure 2 and Figure 3As shown, the gas stove also includes a cooling channel 20 and a liquid supply mechanism 40. The cooling channel 20 includes at least two cooling sections 21, each located below the glass panel 10 and surrounding a clearance hole 11. The liquid supply mechanism 40 includes a cooling medium container 41 and a drive assembly 42. The cooling medium container 41 holds the cooling medium. The two ends of the cooling channel 20 can be selectively connected, allowing the drive assembly 42 to drive the cooling medium to circulate internally within the cooling channel 20. Figure 3 The single arrow in the diagram indicates the flow direction of the cooling medium during the internal circulation process. Both ends of the cooling channel 20 can also be selectively connected to the cooling medium container 41. In this case, the drive assembly 42 can drive the cooling medium to circulate between the cooling channel 20 and the cooling medium container 41, i.e., external circulation. Figure 3 The double arrows in the diagram indicate the flow direction of the cooling medium during the external circulation process. In this embodiment, the cooling medium can be water or oil, and there is no limitation on it.

[0065] When the burner 60 is operating and the temperature of the area around the glass panel 10 near the burner 60 rises, the liquid supply mechanism 40 can drive the cooling medium to flow through the cooling section 21, thereby removing heat from the area around the clearance hole 11 of the glass panel 10, preventing the temperature in this area from rising too high, and thus preventing the glass panel 10 from cracking due to excessive temperature differences between different areas, thereby improving the service life of the gas stove. Furthermore, when the temperature of the area of ​​the glass panel 10 near the burner 60 is slightly high but not too high (i.e., when the cooling demand is low), the cooling medium can be internally circulated. During internal circulation, the amount of cooling medium participating in the circulation is small, resulting in a slow cooling rate and a small cooling effect. Therefore, it can prevent the cooling medium from removing too much heat, which would reduce the thermal efficiency of the gas stove. When the temperature of the area of ​​the glass panel 10 near the burner 60 is very high (i.e., when the cooling demand is high), the cooling medium in the cold zone is externally circulated, thereby rapidly cooling the area of ​​the glass panel 10 near the burner 60, preventing the glass panel 10 from cracking due to excessive temperature differences.

[0066] like Figure 2 and Figure 3As shown, the liquid supply mechanism 40 also includes a first connecting pipe 43, a second connecting pipe 44, a third connecting pipe 45, and a valve assembly 46. The two ends of the first connecting pipe 43 are connected to the two ends of the cooling channel 20, the second connecting pipe 44 connects the first end of the cooling channel 20 to the cooling medium container 41, and the third connecting pipe 45 connects the second end of the cooling channel 20 to the cooling medium container 41. The valve assembly 46 enables the cooling channel 20 to communicate with either the first connecting pipe 43 or the cooling channel 20 with the cooling medium container 41. When the cooling channel 20 is connected to the first connecting pipe 43, the internal circulation path is open; when the cooling channel 20 is connected to the cooling medium container 41, the external circulation path is open. In other words, switching between internal and external circulation can be achieved by changing the state of the valve assembly 46.

[0067] In this embodiment, the cooling channel 20 further includes a connecting section 22 and two docking sections 23. The connecting section 22 connects two adjacent cooling sections 21. One docking section 23 is one end of the entire cooling channel 20, with one end connected to a cooling section 21 and the other end connected to a first connecting pipe 43 and a second connecting pipe 44. The other docking section 23 is the other end of the entire cooling channel 20, with one end connected to another cooling section 21 and the other end connected to a first connecting pipe 43 and a third connecting pipe 45.

[0068] like Figure 2 and Figure 3 As shown, valve assembly 46 includes a first shut-off valve 461 and a second shut-off valve 462. The first shut-off valve 461 is disposed on the first connecting pipe 43, and the second shut-off valve 462 is disposed on the second connecting pipe 44 or the third connecting pipe 45. When the first shut-off valve 461 is open and the second shut-off valve 462 is closed, the two ends of the cooling channel 20 are connected through the first connecting pipe 43, and the cooling medium can circulate internally. When the first shut-off valve 461 is closed and the second shut-off valve 462 is open, the two ends of the cooling channel 20 are connected to the cooling medium container 41 through the first connecting pipe 43 and the second connecting pipe 44, respectively, and the cooling medium can circulate externally. In other embodiments (not shown), valve assembly 46 includes a two-position three-way valve. The first end of the two-position three-way valve is connected to the cooling channel 20, the second end is connected to the first connecting pipe 43, and the third end is connected to the second connecting pipe 44 or the third connecting pipe 45. By switching the state of the two-position three-way valve (either connecting the first end to the second end or connecting the first end to the third end), the switching between internal and external circulation can be realized.

[0069] In this embodiment, as Figure 2 and Figure 3As shown, the drive assembly 42 includes a first drive pump 421 and a second drive pump 422. The first drive pump 421 is disposed on the first connecting pipe 43, and the second drive pump 422 is disposed on the second connecting pipe 44 or the third connecting pipe 45. When the first shut-off valve 461 is open and the second shut-off valve 462 is closed, the first drive pump 421 can drive the cooling medium to circulate internally in the cooling channel 20. When the first shut-off valve 461 is closed and the second shut-off valve 462 is open, the second drive pump 422 can drive the cooling medium to circulate externally in the cooling channel 20 and the cooling medium container 41. In other embodiments (not shown), the drive assembly 42 includes a drive pump disposed on the cooling channel 20. In this scheme, the drive pump can serve as both the driving source for internal circulation and the driving source for external circulation, thus reducing the overall manufacturing cost of the gas stove. Optionally, the drive pump can be installed on the docking section 23 or the connecting section 22; no specific limitation is made here.

[0070] like Figure 2 and Figure 3 As shown, the cooling section 21 is spiral-shaped and is concentrically arranged with the corresponding clearance hole 11. The spiral-shaped cooling section 21 can cool the area around the clearance hole 11 comprehensively and evenly, thereby better preventing the glass panel 10 from cracking due to excessive temperature difference.

[0071] like Figure 3 As shown, the innermost end of the cooling section 21 is its inlet, and the outermost end is its outlet. The cooling medium flows from the innermost to the outermost ring of the cooling section 21. It is understood that the temperature of the cooling medium gradually increases as it flows within the cooling section 21, thus reducing its cooling capacity. During the operation of the burner 60, the temperature is higher and the cooling demand is greater along the radial direction closer to the center of the clearance hole 11. In this embodiment, the cooling medium flows from the innermost to the outermost ring of the cooling section 21, thus matching the cooling capacity of the medium during its flow with the cooling demand of the location it reaches. This ensures a more balanced cooling rate at various radial locations around the clearance hole 11, thereby better preventing the glass panel 10 from cracking due to excessive temperature differences.

[0072] like Figure 3As shown, taking a gas stove with two burners 60 as an example, the second connecting pipe 44 is the outlet end of the cooling medium container 41, and the third connecting pipe 45 is the inlet end of the cooling medium container 41. One end of the first connecting section 23 of the cooling channel 20 is connected to the first connecting pipe 43 and the second connecting pipe 44, and the other end of the first connecting section 23 is connected to the innermost end of the first cooling section 21. The outermost end of the first cooling section 21 is connected to the innermost end of the second cooling section 21 through the connecting section 23. One end of the second connecting section 23 of the cooling channel 20 is connected to the outermost end of the second cooling section 21, and the other end of the second connecting section 23 is connected to the first connecting pipe 43 and the third connecting pipe 45. This arrangement ensures that the cooling medium in each cooling section 21 flows from the inner ring to the outer ring.

[0073] In some embodiments, such as Figure 4 and Figure 5 As shown, the outermost end of the cooling section 21 is the inlet of the cooling section 21, and the innermost end of the cooling section 21 is the outlet of the cooling section 21. This arrangement allows the cooling medium to gradually absorb heat during its flow in the cooling section 21, preventing the cooling medium from absorbing too much heat in the first half of the cooling section 21 and failing to absorb heat in the second half, thus failing to cool the corresponding position of the glass panel 10.

[0074] like Figure 5 As shown, taking a gas stove with two burners 60 as an example, the second connecting pipe 44 is the outlet end of the cooling medium container 41, and the third connecting pipe 45 is the inlet end of the cooling medium container 41. One end of the first connecting section 23 of the cooling channel 20 is connected to the first connecting pipe 43 and the second connecting pipe 44, and the other end of the first connecting section 23 is connected to the outermost end of the first cooling section 21. The innermost end of the first cooling section 21 is connected to the outermost end of the second cooling section 21 through the connecting section 23. One end of the second connecting section 23 of the cooling channel 20 is connected to the innermost end of the second cooling section 21, and the other end of the second connecting section 23 is connected to the first connecting pipe 43 and the third connecting pipe 45. This arrangement ensures that the cooling medium in each cooling section 21 flows from the outer ring to the inner ring.

[0075] In some embodiments, such as Figure 6As shown, the cross-sectional area of ​​the cooling section 21 gradually decreases from the innermost to the outermost ring. It can be understood that the larger the cross-sectional area of ​​the cooling section 21, the larger the heat exchange area between it and the glass panel 10, and the slower the flow velocity of the cooling medium at that location. Therefore, the heat exchange is more efficient, and the cooling capacity is higher. By gradually reducing the cross-sectional area of ​​the cooling section 21 from the inside out, the cooling capacity of the cooling section 21 at each location matches the cooling requirements of the glass panel 10 at the corresponding location. This ensures a more uniform cooling rate of the glass panel 10 in the area surrounding the clearance hole 11, thereby more reliably preventing the glass panel 10 from cracking due to temperature differences.

[0076] In some embodiments, such as Figure 7 As shown, along the radial direction of the clearance hole 11 and from the inside out, the distance between two adjacent rings of the cooling section 21 gradually increases. That is, along the radial direction and closer to the burner 60, the arrangement density of the cooling section 21 gradually increases, thus increasing the corresponding cooling capacity. This arrangement ensures that the cooling capacity of the cooling section 21 matches the cooling requirements of the glass panel 10 at the corresponding position, guaranteeing a more uniform overall cooling rate of the glass panel 10 in the area around the clearance hole 11, thereby more reliably preventing the glass panel 10 from cracking due to large temperature differences.

[0077] like Figure 8 As shown, the gas stove also includes an explosion-proof layer 50, which is adhered to the underside of the glass panel 10. In the event of the glass panel 10 shattering under extreme conditions, the explosion-proof layer 50 can prevent fragments from flying, ensuring user safety. It is understood that, without departing from the inventive concept of this application, the specific material of the explosion-proof layer 50 can be any of the existing technologies, and no specific limitation is made here. Optionally, the explosion-proof layer 50 is attached to the underside of the glass panel 10 by adhesive bonding.

[0078] like Figure 9 As shown, a cooling groove 12 is formed around the clearance hole 11 on the lower side of the glass panel 10. The explosion-proof layer 50 is attached to the lower side of the glass panel 10 and forms a cooling section 21 with the cooling groove 12. In other words, the cooling channel 20 is directly formed between the glass panel 10 and the explosion-proof layer 50, without the need for additional piping, which is conducive to the thinner design of the gas stove.

[0079] Optionally, such as Figure 2As shown, the connecting section 22 of the cooling channel 20 can be a pipe located outside the explosion-proof layer 50 and the glass panel 10, so the cooling medium can dissipate heat during the flow of the cooling medium through the connecting section 22. Alternatively, the connecting section 22 can be formed by creating a groove on the underside of the glass panel 10 and enclosing the explosion-proof layer 50. The two connecting sections 23 of the cooling channel 20 are formed by pipes located outside the explosion-proof layer 50 and the glass panel 10, which not only facilitates connection with the liquid supply mechanism 40, but also allows the cooling medium to dissipate heat when flowing through the connecting sections 23.

[0080] Of course, in other embodiments, the cooling channel 20 can be directly formed inside the glass panel 10, or the cooling channel 20 can be attached to the lower side of the explosion-proof layer 50, which is not limited here.

[0081] like Figure 2 As shown, the gas stove also includes a temperature sensor 30. One temperature sensor 30 is installed at each clearance hole 11, meaning each temperature sensor 30 can detect the temperature of the glass panel 10 surrounding a burner 60. Each temperature sensor 30 is electrically connected to the drive assembly 42. When the detected temperature of a temperature sensor 30 exceeds a certain value, it indicates that the glass panel 10 at that location needs cooling. At this time, the drive assembly 42 drives the cooling medium to circulate internally or externally based on the actual temperature reading of the temperature sensor 30, thereby achieving automatic control of cooling the glass panel 10. In this embodiment, the temperature sensor 30 is located near the innermost ring of the corresponding cooling section 21. The innermost ring is closest to the burner 60, so its temperature rise is the fastest. By placing the temperature sensor 30 at this location, the signal that the glass panel 10 needs cooling can be obtained more quickly, ensuring the reliability of cooling the glass panel 10.

[0082] like Figure 10 As shown, this embodiment also provides a method for controlling a gas stove, which uses the above-mentioned gas stove. The method for controlling the gas stove includes:

[0083] S10, obtain the screening temperature T;

[0084] S11, determine whether the screening temperature T is greater than or equal to the first preset temperature T1. If not, return to step S10; if yes, proceed to step S12.

[0085] S12; Determine whether the screening temperature T is greater than or equal to the second preset temperature T3. If not, drive the cooling medium to circulate internally in the cooling channel 20. If yes, drive the cooling medium to circulate externally between the cooling channel 20 and the cooling medium container 41.

[0086] In this embodiment of the gas stove control method, when the temperature of the area of ​​the glass panel 10 near the burner 60 is greater than or equal to T1 and less than T2, it indicates that the current cooling demand of the glass panel 10 is low. At this time, the cooling medium is circulated internally to prevent the glass panel 10 from cracking due to excessive temperature difference and to prevent the cooling medium from taking away too much heat, which would reduce the thermal efficiency of the gas stove. When the temperature of the area of ​​the glass panel 10 near the burner 60 is greater than or equal to T2, it indicates that the current cooling demand of the glass panel 10 is high. At this time, the cooling medium is circulated externally to quickly cool the area of ​​the glass panel 10 near the burner 60, thereby preventing the glass panel 10 from cracking due to excessive temperature difference.

[0087] In this embodiment, the screening temperature T is obtained by acquiring the detection results of each temperature sensor 30, thereby obtaining the detected temperature of the glass panel 10 at each burner 60, and the screening temperature T is the maximum value among all detected temperatures. That is, as long as the temperature of the glass panel 10 around any burner 60 rises to the first preset temperature, the cooling medium circulation is activated to ensure timely and reliable cooling, thereby improving the service life of the gas stove.

[0088] like Figure 10 As shown, after driving the cooling medium through internal or external circulation, the process returns to step S10 to re-acquire the current screening temperature T. Furthermore, when step S11 determines that the screening temperature T is less than the first preset temperature T1, it indicates that the glass panel 10 no longer needs cooling. The driving of the cooling medium in the cold zone is then stopped, and the process returns to step S10. This ensures that cooling is timely when the glass substrate requires cooling, and that cooling is stopped promptly when it no longer needs cooling, avoiding unnecessary circulation of the cooling medium and increased energy consumption.

[0089] In actual use of gas stoves, all burners 60 may be in use at the same time, and turning on the internal circulation will not produce a significant cooling effect.

[0090] like Figure 11 As shown, this embodiment also provides another method for controlling a gas stove, which also applies the above-mentioned gas stove. The method for controlling the gas stove includes:

[0091] S10, obtain the screening temperature T, and the operating status of all burners 60;

[0092] S101, determine whether all burners 60 are in combustion state. If not, proceed to step S11; if yes, proceed to step S21.

[0093] S11, determine whether the screening temperature T is greater than or equal to the first preset temperature T1. If not, return to step S10; if yes, proceed to step S12.

[0094] S12; Determine whether the screening temperature T is greater than or equal to the second preset temperature T3. If not, drive the cooling medium to circulate internally in the cooling channel 20. If yes, drive the cooling medium to circulate externally between the cooling channel 20 and the cooling medium container 41.

[0095] S21, determine whether the screening temperature T is greater than or equal to the first preset temperature T1. If not, return to step S10. If yes, drive the cooling medium to circulate externally between the cooling channel 20 and the cooling medium container 41.

[0096] The control method of the gas stove in this embodiment first obtains the working status of all burners 60. When all burners 60 are in the combustion state and the screening temperature T is greater than the first preset temperature, the external circulation is immediately turned on. This avoids the step of first turning on the internal circulation and then switching to the external circulation. This can ensure the timeliness of cooling and reduce the start-stop switching of each drive pump, thereby improving the service life of the drive pump.

[0097] It can be understood that the specific way to obtain the working status of the burner 60 is to obtain whether the gas valve at the inlet of each burner 60 is open.

[0098] In this embodiment, the screening temperature T is obtained by acquiring the detection results of each temperature sensor 30, thereby obtaining the detected temperature of the glass panel 10 at each burner 60, and the screening temperature T is the maximum value among all detected temperatures. That is, as long as one burner 60 is working and the temperature of the glass panel 10 around it rises to the first preset temperature, the cooling medium circulation is started to ensure timely and reliable cooling, thereby improving the service life of the gas stove.

[0099] like Figure 11 As shown, after driving the cooling medium to perform internal or external circulation, the process returns to step S10 to re-acquire the current screening temperature T. If the screening temperature T is determined to be less than the first preset temperature T1, it indicates that the glass panel 10 no longer needs cooling. Therefore, the driving of the cooling medium in the cold zone is stopped before returning to step S10. This ensures that cooling is timely when the glass substrate requires cooling, and that cooling is stopped promptly when it no longer needs cooling, avoiding unnecessary medium circulation and increased energy consumption.
