[0002] Currently, most stoves on the market use passive defense methods to address safety issues such as gas leaks and overheating.

However, these methods often fail to detect problems in a timely manner or may not be detected at all when the person is not present.

[0003] In addition, ion-type cooktops consume more electricity than traditional thermocouple cooktops, thus requiring connection to mains power, which leads to a poor user experience. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of the claimed technical solutions of the invention.

[0044] Example 1:

[0045] like Figures 1 to 4 As shown, this embodiment provides a stove, which includes a housing 1, a gas leak detector 2, and a controller 7. The gas leak detector 2 is disposed inside the housing 1 to detect gas leaks inside the housing 1, and the controller 7 is electrically connected to the gas leak detector 2.

[0046] In this embodiment, the gas leak detection device is preferably applied to a stove. The stove includes a housing 1, a burner 11 is provided on the housing 1, and an air inlet pipe is provided inside the housing 1. The burner 11 is connected to an external gas supply through the air inlet pipe. A gas leak detector 2 is provided inside the housing 1, so that the gas leak detector 2 can obtain the gas leak status of the stove by detecting the environmental conditions inside the housing 1, thereby effectively improving the reliability of gas leak detection of the stove. Its structure is simple and enables the stove to actively detect gas leaks.

[0047] More preferably, the gas leak detector 2 is a methane sensor, which actively detects the methane concentration in the environment to obtain information about gas leaks in the stove.

[0048] Furthermore, it also includes a partition 3, and the stove also includes a burner 11 disposed on the housing 1. The partition 3 is disposed inside the housing 1 to separate the lower end of the burner 11 from the gas leak detector 2.

[0049] Preferably, a receiving cavity 12 is defined inside the housing 1, and a partition 3 is disposed inside the receiving cavity 12 to divide the receiving cavity 12 into a first cavity 121 and a second cavity 122. A gas leak detector 2 is disposed inside the first cavity 121, and a burner head 11 is disposed inside the second cavity 122. A communication port 31 is provided on the partition 3, and the communication port 31 is disposed corresponding to the gas leak detector 2.

[0050] In this embodiment, a receiving cavity 12 is defined within the housing 1. A partition 3 is disposed within the receiving cavity 12 to divide the receiving cavity 12 into a first cavity 121 and a second cavity 122. The partition 3 also enables heat insulation between the first cavity 121 and the second cavity 122. A gas leak detector 2 is disposed within the first cavity 121, and a burner 11 is disposed within the second cavity 122, thereby separating the gas leak detector 2 from the burner 11 and preventing the high temperature of the burner 11 from affecting the accuracy of the gas leak detector 2. To more effectively detect gas leaks in the stove, a connecting port 31 is provided on the partition 3. The connecting port 31 is correspondingly disposed with the gas leak detector 2. The first cavity 121 and the second cavity 122 are interconnected through the connecting port 31, allowing the gas leak detector 2 to detect gas leaks in the burner 11 within the second cavity 122 through the connecting port 31.

[0051] Furthermore, it also includes a heat dissipation component 4 electrically connected to the controller 7, which is disposed inside the housing 1 to dissipate heat from the housing 1 to the outside.

[0052] Preferably, the heat dissipation assembly 4 includes an air inlet shroud 41, an exhaust pipe 45, and a heat dissipation fan 46. The air inlet shroud 41 is disposed inside the housing 1, and air inlets 43 are respectively opened on the circumferential side walls of the air inlet shroud 41. The heat dissipation fan 46 is disposed inside the air inlet shroud 41, and an exhaust port is opened on the rear side wall of the air inlet shroud 41. One end of the exhaust pipe 45 is connected to the exhaust port, and the other end is connected to the outside.

[0053] Specifically, the heat dissipation assembly 4 also includes an air outlet shroud 42, which is disposed on the upper wall of the housing 1. The exhaust pipe 45 is connected to the air outlet shroud 42 at the end away from the exhaust port, and an exhaust port 44 is provided on the upper wall of the air outlet shroud 42.

[0054] Preferably, a heat dissipation channel 13 is defined at the lower end of the housing 1, the front end of the heat dissipation channel 13 is connected to the outside, and an exhaust pipe 46 is provided on the bottom wall of the air inlet shroud 41, the exhaust pipe 46 is connected to the rear end of the heat dissipation channel 13.

[0055] Furthermore, it also includes a temperature sensor 5 electrically connected to the controller 7, and the temperature sensor 5 is disposed in the first cavity 121.

[0056] In this embodiment, a heat dissipation assembly 4 is provided inside the housing 1. More preferably, the heat dissipation assembly 4 is located inside the second cavity 122, thereby facilitating the heat dissipation assembly 4 to expel heat from inside the housing 1. The air inlet shroud 41 of the heat dissipation assembly 4 is provided inside the second cavity 122 of the housing 1. Air inlets 43 are respectively provided on the circumferential sidewalls of the air inlet shroud 41. A heat dissipation fan 46 is provided inside the air inlet shroud 41 to introduce heat from inside the housing 1 into the air inlet shroud 41 through the air inlets 43. Since burner heads 11 are respectively provided on the left and right ends of the housing 1, thus... The air inlet hood 41 can be positioned in the middle of the two burners 11. Simultaneously, the air inlet 43 at the front end of the air inlet hood 41 dissipates heat from the first cavity 121 through the connecting port 31. The air inlet 43 at the left end of the air inlet hood 41 dissipates heat generated on the burner 11 at the left end of the housing 1, and the air inlet 43 at the right end of the air inlet hood 41 dissipates heat generated on the burner 11 at the right end of the housing 1. An exhaust port is provided on the side wall at the rear end of the air inlet hood 41, with one end of the exhaust pipe 45 connected to the exhaust port and the other end connected to the outside. More preferably, since a temperature sensor 5 is installed inside the housing 1, preferably within the first cavity 121, the reliability of temperature detection can be improved more effectively. The temperature sensor 5 detects the temperature inside the housing 1 to obtain the temperature conditions inside the housing 1. Then, the controller 7 controls the operation of the cooling fan 46 based on the temperature detected by the temperature sensor 5, thereby effectively improving the heat dissipation effect of the stove.

[0057] In addition, the air outlet hood 42 is installed on the upper wall of the housing 1, the exhaust pipe 45 is connected to the air outlet hood 42 at the end away from the exhaust port, and an air outlet 44 is opened on the upper wall of the air outlet hood 42, so that the hot air entering the air inlet hood 41 is discharged outward after passing through the exhaust port, the exhaust pipe 45, the air outlet hood 42, and the air outlet 44 in sequence. More preferably, when the cooktop is installed on the integrated cooktop, a heat dissipation channel 13 is defined at the lower end of the housing 1. That is, the heat dissipation channel 13 is set on the body of the integrated cooktop, and the heat dissipation channel 13 can exhaust the heat generated by the cooking appliances on the integrated cooktop. The front end of the heat dissipation channel 13 is connected to the outside. An exhaust pipe 46 is opened on the bottom wall of the air inlet hood 41 and is connected to the rear end of the heat dissipation channel 13. When the heat generated by the cooking appliances is discharged into the heat dissipation channel 13, the heat dissipation fan 46 is started to rotate. The outside air enters the heat dissipation channel 13 through the front end of the heat dissipation channel 13 to exchange heat with the hot air in the heat dissipation channel 13. Then the heat-exchanged hot air is introduced into the air inlet hood 41 through the exhaust pipe 46. Then the hot air entering the air inlet hood 41 is discharged out through the exhaust pipe 45, thereby effectively improving the heat dissipation efficiency of the product.

[0058] Specifically, it also includes a rechargeable battery 6 electrically connected to the controller 7, the rechargeable battery 6 being disposed within the first cavity 121.

[0059] In this embodiment, a rechargeable battery 6 is provided inside the housing 1. The rechargeable battery 6 is connected to an external mains power supply to enable charging, so that the stove can be used normally without mains power, thereby effectively improving the user experience.

[0060] Example 2:

[0061] like Figure 5 As shown, this embodiment provides a control method for a stove, which is applied to any stove as described in Embodiment 1, thereby enabling it to have the technical effect of a stove gas leakage detection device. The method is simple and feasible, and can actively detect the methane concentration and ambient temperature in the environment, and control the speed of the cooling fan to perform active heat dissipation according to the current environmental conditions.

[0062] The control method for the stove in this embodiment specifically includes the following steps:

[0063] In step S101, the leakage situation is pre-classified into multiple concentration levels based on the methane concentration value.

[0064] In this embodiment, the leakage situation is pre-classified into a first concentration level, a second concentration level, and a third concentration level based on the methane concentration value. The methane concentration value of the first concentration level is less than that of the second concentration level, the methane concentration value of the second concentration level is less than that of the third concentration level, and the methane concentration value of the third concentration level is less than the concentration threshold.

[0065] Step S102: Start the stove and check the current methane concentration inside the casing.

[0066] After starting the stove, first determine if it is connected to external mains power; if so, charge the rechargeable battery; if not, activate the rechargeable battery to provide power. Then, check the current methane concentration inside the casing.

[0067] In step S103, determine whether the current methane concentration is greater than the concentration threshold; if yes, stop working and issue an alarm signal; if no, check the temperature inside the shell.

[0068] In this embodiment, if the current methane concentration is greater than the concentration threshold, the stove will stop working and issue an alarm signal, while simultaneously turning off the mains power supply and starting the rechargeable battery to provide power.

[0069] In step S104, the rotation speed of the cooling fan is calculated based on the current methane concentration level and the current temperature. The cooling fan then rotates according to the calculated rotation speed.

[0070] In this embodiment, the rotational speed of the cooling fan is calculated using the following formula: n=(s+

[0071] (T / 25))*a, where n is the rotation speed of the cooling fan, s is the concentration level of the current methane concentration, T is the current temperature inside the shell, 25 is 25℃, and a is a coefficient.

[0072] More preferably, if the current methane concentration is at the first concentration level, then s is 1, the cooling fan rotates according to the calculated speed, and at the same time controls the stove to ignite.

[0073] If the current methane concentration is at the second concentration level, then s is 2, the cooling fan rotates according to the calculated speed, and the range hood is started to exhaust air at the same time.

[0074] If the current methane concentration is at level 3, then s is 3. The cooling fan rotates at the calculated speed, the range hood is started for ventilation, the mains power is turned off, and the rechargeable battery is started for power supply.

[0075] Furthermore, a is between 800 and 1800, preferably a is 1050.

[0076] The above descriptions are merely some embodiments of the present invention.
