[0028] Figure 1 It is a schematic flow chart of a self - cleaning control method for an integrated range hood provided by an embodiment of the present invention. Figure 2 It is a schematic flow chart of another self - cleaning control method for an integrated range hood provided by an embodiment of the present invention. This embodiment is applicable to the cleaning of the range hood in the integrated range hood. This method can be executed by a self - cleaning control device, which can be implemented in the form of hardware and / or software, and the self - cleaning control device can be configured in the controller of the integrated range hood.

[0029] As Figure 1 and Figure 2 shown, the self - cleaning control method provided by the embodiment of the present invention includes:

[0030] S100. Control the steam cleaning component to inject steam into the turbine.

[0031] S200. Control the hot - water cleaning component to inject hot water into the turbine.

[0032] Among them, controlling the steam cleaning component to inject steam into the turbine includes:

[0033] S110. Obtain the humidity in the steam cleaning pipeline through a humidity sensor.

[0034] S120. When the humidity is less than or equal to the preset humidity, turn on the steam generator, and control the steam cleaning component to inject the steam generated by the steam generator into the turbine.

[0035] S130. When the humidity is greater than the preset humidity, control the steam cleaning component to inject the steam in the cooking cavity into the turbine.

[0036] Wherein, Figure 3 is a schematic structural diagram of an integrated stove provided by an embodiment of the present invention. As Figure 3 shown, the integrated stove includes a steam box 1, an oil fume extractor 2, a steam cleaning component 3 and a hot water cleaning component 4. The steam box 1 includes a cooking cavity 11, a cooking cavity exhaust pipe 12 and a steam generator 13. The steam cleaning component 3 includes a steam cleaning pipeline 31. The intake end of the steam cleaning pipeline 31 is respectively communicated with the cooking cavity exhaust pipe 12 and the steam output port of the steam generator 13. The outlet end of the steam cleaning pipeline 31 is fluidly connected to the turbine 5 of the oil fume extractor 2. A humidity sensor 32 is provided on the steam cleaning pipeline 31.

[0037] Specifically, as Figure 3 shown, the steam box 1 can be a device for cooking in the integrated stove. The steam box 1 includes a cooking cavity 11, a cooking cavity exhaust pipe 12 and a steam generator 13. The cooking cavity 11 can be a cavity for cooking in the steam box 1, used for placing food materials. The steam generator 13 can be a device that uses the physical properties of liquid water to heat the liquid water to the boiling point and convert it into water vapor, and is applied to the cooking function and / or the cleaning function. The steam output port of the steam generator 13 is fluidly connected to the cooking cavity 11 to introduce the generated steam into the cooking cavity 11. During the operation of the steam box 1, the object to be cooked is placed in the cooking cavity 11, and the steam generator 13 is started. The steam generator 13 works to generate a large amount of high-temperature steam. The high-temperature steam is transported to the cooking cavity 11 to heat the object to be cooked in the cooking cavity 11. The cooking cavity exhaust pipe 12 is connected to the cooking cavity 11. The cooking cavity exhaust pipe 12 can be a pipeline for transporting the waste steam during the cooking process, that is, the waste steam in the cooking cavity 11 can be discharged from the cooking cavity exhaust pipe 12.

[0038] Continue to refer to Figure 3 , a water tank 14 is further provided in the steam box 1. The steam generator 13 can be connected to the water tank 14, and the water tank 14 is used to supply liquid water to the steam generator 13.

[0039] Furthermore, the oil fume extractor 2 is used to extract the oil fume generated during the cooking process. Among them, a turbine 5 is provided in the oil fume extractor 2. The turbine 5 can be a device for controlling the suction force of the oil fume extractor 2. The turbine 5 rotates to provide suction force, and the suction force of the oil fume extractor 2 is controlled by controlling its rotation speed.

[0040] Continue to refer to Figure 3, the steam cleaning assembly 3 can be used to deliver steam to the range hood 2 for the purpose of cleaning the range hood 2. Among them, the intake end of the steam cleaning pipeline 31 is communicated with the cooking cavity exhaust pipe 12, so that it can be used to deliver the waste steam generated after cooking food with high-temperature steam in the cooking cavity 11 into the range hood 2; at the same time, the intake end of the steam cleaning pipeline 31 is also communicated with the steam output port of the steam generator 13, so that it can be used to directly deliver the steam generated by the steam generator 13 into the range hood 2.

[0041] The outlet end of the steam cleaning pipeline 31 is fluidly connected to the turbine 5 of the range hood 2. The steam cleaning pipeline 31 can be used to deliver steam to the turbine 5 in the range hood 2, and use the temperature and humidity of the steam to soften the oil stains adsorbed on the turbine 5, so that the oil stains on the turbine 5 can be discharged. Among them, on the one hand, the steam can be sourced from the waste steam generated during the operation of the cooking cavity 11, and on the other hand, it can be sourced from the steam directly delivered by the steam generator 13.

[0042] Continue to refer to Figure 3 , the humidity sensor 32 can be used to detect the humidity in the steam cleaning pipeline 31, so as to judge whether the steam transmitted through the steam cleaning pipeline 31 can meet the cleaning requirements of the turbine 5 based on the humidity in the steam cleaning pipeline 31, and further control whether the steam generator 13 is turned on according to the humidity in the steam cleaning pipeline 31.

[0043] Exemplarily, in this embodiment, when controlling the steam cleaning assembly 3 to inject steam into the turbine 5, the humidity in the steam cleaning pipeline 31 is obtained through the humidity sensor 32.

[0044] Among them, when it is detected by the humidity sensor 32 that the humidity in the steam cleaning pipeline 31 is less than or equal to the preset humidity, it can be judged that the steam volume in the steam cleaning pipeline 31 is insufficient to meet the cleaning requirements of the turbine 5. At this time, the steam generator 13 is turned on, and the steam generated by the steam generator 13 is introduced into the turbine 5 through the steam cleaning pipeline 31 to clean the turbine 5.

[0045] When it is detected by the humidity sensor 32 that the humidity in the steam cleaning pipeline 31 is greater than the preset humidity, it can be judged that the steam volume in the steam cleaning pipeline 31 can meet the cleaning requirements of the turbine 5. At this time, there is no need to additionally turn on the steam generator 13.

[0046] It should be noted that the preset humidity can be set according to the cleaning requirements of the turbine 5. For example, the preset humidity is set to the ambient humidity. That is, when the humidity in the steam cleaning pipeline 31 detected by the humidity sensor 32 is less than or equal to the ambient humidity, it indicates that the steaming oven 1 is not working at this time, and there is no steam in the cooking cavity 11 entering the steam cleaning pipeline 31 through the cooking cavity exhaust pipe 12, so that the steam volume in the steam cleaning pipeline 31 is insufficient to meet the cleaning requirements of the turbine 5. At this time, the steam generator 13 is turned on, and the steam generated by the steam generator 13 is introduced into the turbine 5 through the steam cleaning pipeline 31 to clean the turbine 5.

[0047] When the humidity in the steam cleaning pipeline 31 detected by the humidity sensor 32 is greater than the ambient humidity, it indicates that the steaming oven 1 is working at this time, and the steam in the cooking cavity 11 enters the steam cleaning pipeline 31 through the cooking cavity exhaust pipe 12, so that the steam volume in the steam cleaning pipeline 31 can meet the cleaning requirements of the turbine 5. At this time, there is no need to turn on the steam generator 13 additionally, and the steam in the cooking cavity 11 is used to clean the turbine 5 to reduce energy waste. At the same time, it can also prevent the steam in the cooking cavity 11 from being directly discharged into the environment, causing the kitchen wall to be damp.

[0048] It should be noted that the type of the humidity sensor 32 in the embodiment of the present invention is not specifically limited, as long as it has the function of detecting humidity. For example, the humidity sensor 32 is set as a temperature and humidity sensor to realize the temperature detection function, and those skilled in the art can set it according to actual needs.

[0049] Continue to refer to Figure 3 , the integrated stove is also provided with a hot water cleaning component 4, and the hot water cleaning component 4 is used to directly supply hot water to the turbine 5 to wash the turbine 5.

[0050] In this embodiment, after the steam cleaning component 3 injects steam into the turbine 5, the steam softens the oil stains on the turbine 5, and then hot water is introduced into the turbine 5 through the hot water cleaning component 4 to wash the softened oil stains on the turbine 5, so as to achieve the purpose of thoroughly cleaning the turbine 5.

[0051] Specifically, the user can activate the cleaning mode on the keypad of the range hood 2. At this time, first control the steam cleaning component 3 to inject steam into the turbine 5 to soften the oil stains on the turbine 5. Specifically, the humidity sensor 32 is used to detect the humidity in the steam cleaning pipeline 31. When the humidity in the steam cleaning pipeline 31 is less than or equal to the preset humidity, the steam generator 13 is activated. The steam generated by the steam generator 13 enters the steam cleaning pipeline 31 from the steam outlet. The steam cleaning pipeline 31 transports the steam to the turbine 5 to soften the oil stains on the turbine 5. After the oil stains are softened, the hot water cleaning component 4 is started. The hot water cleaning component 4 transports hot water to the turbine 5 to rinse the oil stains on the turbine 5, achieving the purpose of cleaning the range hood 2.

[0052] When the humidity in the steam cleaning pipeline 31 is greater than the preset humidity, at this time, the steam box 1 is in the working state, and the steam discharged from the cooking cavity 11 of the steam box 1 is sufficient to clean the turbine 5. The steam in the cooking cavity 11 enters the steam cleaning pipeline 31 from the cooking cavity exhaust pipe 12. The steam cleaning pipeline 31 transports the steam to the turbine 5 to soften the oil stains on the turbine 5. After softening, the hot water cleaning component 4 is started. The hot water cleaning component 4 transports hot water to the turbine 5 to rinse the oil stains on the turbine 5, achieving the purpose of cleaning the range hood 2.

[0053] In summary, the self-cleaning control method of the integrated stove provided by the embodiment of the present invention sets a steam cleaning component and a hot water cleaning component in the integrated stove. By controlling the steam cleaning component to inject steam into the turbine, the oil stains on the turbine are softened, and then by controlling the hot water cleaning component to inject hot water into the turbine, the oil stains on the turbine are rinsed, thereby realizing the thorough cleaning of the turbine. At the same time, when controlling the steam cleaning component to inject steam into the turbine, the humidity in the steam cleaning pipeline of the steam cleaning component is detected by the humidity sensor, and the steam generator is controlled to start according to the humidity in the steam cleaning pipeline. Thus, when the steam in the cooking cavity is not sufficient to meet the cleaning requirements of the turbine, the steam generator is started to generate steam to clean the turbine, improving the cleaning efficiency.

[0054] Continue to refer to Figure 3 Optionally, the steam cleaning component 3 further includes a control valve 33. The control valve 33 includes an inlet 330, a first outlet 331, and a second outlet 332. The steam outlet of the steam generator 13 is connected to the inlet 330. The first outlet 331 is communicated with the cooking cavity 11, and the second outlet 332 is connected to the air inlet end of the steam cleaning pipeline 31.

[0055] Controlling the steam cleaning component 3 to inject the steam generated by the steam generator 13 into the turbine 5 includes:

[0056] The inlet 330 and the second outlet 332 are connected by the control valve 33 , and the first outlet 331 is closed, so that the steam generated by the steam generator 13 is injected into the turbine 5 through the inlet 330 , the second outlet 332 and the steam cleaning pipeline 31 .

[0057] Controlling the steam cleaning assembly 3 to inject the steam in the cooking cavity 11 into the turbine 5 includes:

[0058] The inlet 330 is connected to the first outlet 331 through the control valve 33 , and the second outlet 332 is closed, so that the steam in the cooking cavity 11 is injected into the turbine 5 through the cooking cavity exhaust pipe 12 and the steam cleaning pipeline 31 .

[0059] The control valve 33 may be used to control the steam generated by the steam generator 13 to enter the cooking cavity 11 or the steam cleaning pipeline 31 .

[0060] Specifically, when the control valve 33 connects the inlet 330 and the first outlet 331 and closes the second outlet 332 , the steam generated by the steam generator 13 enters the cooking cavity 11 through the inlet 330 and the first outlet 331 to cook the food in the cooking cavity 11 .

[0061] When the control valve 33 connects the inlet 330 and the second outlet 332 and closes the first outlet 331 , the steam generated by the steam generator 13 enters the steam cleaning pipeline 31 through the inlet 330 and the second outlet 332 to clean the turbine 5 .

[0062] Figure 4 A flow chart of another self-cleaning control method for an integrated stove provided by an embodiment of the present invention is shown as follows: Figure 4 As shown, illustratively, the user can turn on the cleaning mode on the keypad of the range hood 2 . At this time, the steam cleaning component 3 is first controlled to inject steam into the turbine 5 to soften the oil stains on the turbine 5 .

[0063] When the steam cleaning component 3 is controlled to inject steam into the turbine 5, the humidity in the steam cleaning pipeline 31 is detected by the humidity sensor 32. When the humidity in the steam cleaning pipeline 31 is detected by the humidity sensor 32 to be less than or equal to the preset humidity, it means that the steam box 1 is not working at this time, and no steam in the cooking cavity 11 enters the steam cleaning pipeline 31 through the cooking cavity exhaust pipe 12, so that the amount of steam in the steam cleaning pipeline 31 is insufficient to meet the cleaning demand of the turbine 5. At this time, the steam generator 13 is turned on, and at the same time, the control valve 33 is controlled to close the first outlet 331, and the inlet 330 is connected with the second outlet 332, so as to prevent the steam generated by the steam generator 13 from leaking into the cooking cavity 11, and all the steam is discharged from the second outlet 332 to the steam cleaning pipeline 31, thereby achieving the cleaning of the turbine 5.

[0064] When the humidity in the steam cleaning pipeline 31 detected by the humidity sensor 32 is greater than the preset humidity, it indicates that the steam box 1 is working at this time. The steam in the cooking cavity 11 enters the steam cleaning pipeline 31 through the cooking cavity exhaust pipe 12, so that the steam volume in the steam cleaning pipeline 31 can meet the cleaning requirements of the turbine 5. At this time, the control valve 33 is controlled to close the second outlet 332 and connect the inlet 330 with the first outlet 331. All the steam generated by the steam generator 13 enters the cooking cavity 11 from the first outlet 331 and is finally discharged to the steam cleaning pipeline 31 through the cooking cavity exhaust pipe 12, thereby realizing the cleaning of the turbine 5. Thus, the utilization of the steam in the cooking cavity 11 can be realized, energy waste can be reduced. At the same time, the steam in the cooking cavity 11 can be prevented from being directly discharged into the environment, causing the kitchen wall to be damp.

[0065] In this embodiment, by controlling the conveying direction of the steam in the steam generator 13 through the control valve 33, while ensuring the cooking function of the steam box 1, the waste steam in the cooking cavity 11 is fully utilized to realize the cleaning of the turbine 5. At the same time, when the waste steam in the cooking cavity 11 is insufficient, the steam generator 13 is timely turned on to supplement the steam volume to the turbine 5, and the control valve 33 is used to prevent the steam generated by the steam generator 13 from leaking into the cooking cavity 11, ensuring the cleaning efficiency of the turbine 5.

[0066] Figure 5 It is a schematic flowchart of another self-cleaning control method for the integrated stove provided by the embodiment of the present invention, as Figure 3 and Figure 5 shown. Optionally, the hot water cleaning component 4 includes an electric heater 41, a spray pipe 42, a spray pump 43 and a spray head 44. The water inlet of the spray pipe 42 is connected to the water tank 14 of the steam box 1, the water outlet of the spray pipe 42 is connected to the spray head 44, the spray head 44 is arranged towards the turbine 5, and the electric heater 41 and the spray pump 43 are arranged on the spray pipe 42.

[0067] Controlling the hot water cleaning component 4 to inject hot water into the turbine 5 includes:

[0068] S210. Pump the water in the water tank 14 into the spray pipe 42 through the spray pump 43.

[0069] S220. Heat the water in the spray pipe 42 into hot water through the electric heater 41.

[0070] S230. Inject the hot water into the turbine 5 through the spray head 44.

[0071] Among them, as Figure 3As shown, the water tank 14 is used to provide a water source for the hot water cleaning assembly 4, and the electric heater 41 is used to heat the water in the spray pipe 42 to increase the water temperature, so as to achieve the purpose of thoroughly cleaning the oil stains condensed in the turbine 5. The spray pump 43 is used to suck the water in the water tank 14 into the spray pipe 42 to realize the transportation of water. The spray pipe 42 is used to transport the water in the water tank 14 to the spray head 44 in the range hood 2. By arranging the spray head 44 facing the turbine 5, the spray head 44 can spray hot water towards the turbine 5, and the hot water forms a jet flow and impacts on the turbine 5, thereby flushing the turbine 5, which is beneficial to improving the hot water flushing strength and flushing range and enhancing the cleaning strength.

[0072] In this embodiment, when controlling the hot water cleaning assembly 4 to inject hot water into the turbine 5, the water in the water tank 14 is pumped into the spray pipe 42 by the spray pump 43, the water in the spray pipe 42 is heated by the electric heater 41, and after being heated to the preset temperature, the hot water is transported from the spray pipe 42 to the spray head 44, and the hot water is sprayed onto the turbine 5 through the spray head 44 to achieve the purpose of cleaning the turbine 5.

[0073] Among them, the electric heater 41 heats the water and transports the hot water heated to the preset temperature to the turbine 5 for oil stain flushing, avoiding that after the steam softens the oil stains, the cold water condenses the oil stains again. The electric heater 41 is arranged on the spray pipe 42, which is convenient to directly heat the water in the spray pipe 42 to the preset temperature and transport it to the range hood 2 through the spray pipe 42, ensuring the cleaning efficiency of the turbine 5.

[0074] It should be noted that when controlling the steam cleaning assembly 3 to inject steam into the turbine 5, the spray pump 43 can be started to pump the water in the water tank 14 into the spray pipe 42, and the water is transported to the electric heater 41. The electric heater 41 maintains the water in the spray pipe 42 at the preset temperature. Such a setting helps to save the heating time of the water and improve the flushing speed of the hot water on the turbine 5.

[0075] Optionally, the hot water cleaning assembly 4 further includes a temperature sensor (not shown in the figure) arranged on the spray pipe 42.

[0076] Injecting hot water into the turbine 5 through the spray head 44 includes:

[0077] Obtaining the temperature of the hot water in the spray pipe 42 through the temperature sensor.

[0078] When the temperature is greater than or equal to the preset temperature, inject hot water into the turbine 5 through the spray head 44.

[0079] Specifically, the temperature sensor can be used to detect the water temperature in the spray pipe 42. The temperature of the hot water in the spray pipe 42 can be obtained through the temperature sensor, and the electric heater 41 can be controlled to heat according to the temperature of the hot water in the spray pipe 42. When the temperature of the hot water in the spray pipe 42 reaches the preset temperature, the hot water is injected into the turbine 5 through the spray head 44, so as to ensure that the water input into the turbine 5 is hot water and improve the cleaning efficiency of the turbine 5.

[0080] Among them, the preset temperature can be 80°C to 100°C to ensure that the hot water input into the turbine 5 can effectively wash away the oil stains, but it is not limited to this.

[0081] Figure 6 It is a schematic flow chart of another self-cleaning control method of the integrated stove provided by the embodiment of the present invention. As Figure 6 shown, exemplarily, when controlling the hot water cleaning component 4 to inject hot water into the turbine 5, first turn on the spray pump 43 to pump the water in the water tank 14 into the spray pipe 42, and then heat the water in the spray pipe 42 to hot water through the electric heater 41. When the temperature of the hot water in the spray pipe 42 detected by the temperature sensor is less than the preset temperature, the electric heater 41 continues to heat the water in the spray pipe 42; when the temperature of the hot water in the spray pipe 42 detected by the temperature sensor is greater than or equal to the preset temperature, the electric heater 41 stops heating, and the spray head 44 is opened to spray the hot water into the turbine 5 to achieve the purpose of cleaning the turbine 5.

[0082] Figure 7 It is a schematic partial structure diagram of an integrated stove provided by the embodiment of the present invention. As Figure 7 shown, optionally, the hot water cleaning component 4 includes a water pump 40 arranged on the steam cleaning pipeline 31.

[0083] Controlling the hot water cleaning component 4 to inject hot water into the turbine 5 includes:

[0084] Generating hot water through the steam generator 13.

[0085] Injecting the hot water generated by the steam generator 13 into the turbine 5 through the steam cleaning pipeline 31 by means of the water pump.

[0086] Among them, the steam generator 13 can also be used to generate hot water, and the water pump 40 is used to extract the hot water generated by the steam generator 13 into the steam cleaning pipeline 31, so as to inject the hot water into the turbine 5 through the steam cleaning pipeline 31 to achieve the flushing of the turbine 5.

[0087] Specifically, after controlling the steam cleaning assembly 3 to inject steam into the turbine 5, the steam softens the oil stains on the turbine 5. Then, using the temperature sensor inside the steam generator 13, the water in the water tank 14 is heated to a preset temperature by the steam generator 13, and then the hot water generated by the steam generator 13 is pumped into the steam cleaning pipeline 31 by the water pump 40. The steam cleaning pipeline 31 delivers the hot water to the turbine 5 to achieve the flushing of the turbine 5.

[0088] Among them, by generating hot water through the steam generator 13 and using the steam cleaning pipeline 31 to further deliver the hot water to the turbine 5, a separate hot water pipeline can be eliminated, enabling the hot water and steam to use the same steam cleaning pipeline 31, thereby saving additional devices and pipeline laying and reducing costs.

[0089] Optionally, when controlling the steam cleaning assembly 3 to inject steam into the turbine 5, it further includes:

[0090] Controlling the turbine 5 to rotate at a first speed.

[0091] Specifically, when controlling the steam cleaning assembly 3 to inject steam into the turbine 5, the rotation of the turbine 5 can be controlled to increase the contact area of the steam on the turbine 5, enabling the turbine 5 to fully contact the steam and soften the oil stains on the turbine 5.

[0092] Meanwhile, when the humidity in the steam cleaning pipeline 31 is greater than the preset humidity, it indicates that the steaming box 1 is in the working state. At this time, starting the rotation of the turbine 5 also helps to discharge the steam in the cooking cavity 11 of the steaming box 1 through the steam cleaning pipeline 31, thereby delivering the steam in the cooking cavity 11 to the turbine 5.

[0093] Among them, the turbine 5 rotates at a first speed, and the first speed can be set to a relatively slow speed to enable the turbine 5 to fully contact the steam and enhance the softening effect of the steam on the oil stains on the turbine 5. For example, the first speed is set to 1 revolution per second, but it is not limited thereto.

[0094] Meanwhile, when the turbine 5 rotates at the first speed, it can rotate clockwise or counterclockwise. The embodiments of the present invention do not limit the rotation direction and speed of the turbine 5.

[0095] When the steam cleaning assembly 3 injects steam into the turbine 5, controlling the turbine 5 to rotate at the first speed enables the turbine 5 to fully contact the steam and soften the oil stains on the steam, enhancing the effect of the steam on the turbine 5.

[0096] Optionally, when controlling the hot water cleaning assembly 4 to inject hot water into the turbine 5, it further includes:

[0097] Controlling the turbine 5 to rotate forward and backward alternately at a second speed, where the second speed is greater than the first speed.

[0098] Specifically, when controlling the hot water cleaning component 4 to inject hot water into the turbine 5, the turbine 5 can be controlled to rotate forward and backward alternately at the second rotation speed, so as to shake off the oil stains on the turbine 5.

[0099] Among them, the forward and backward alternating rotation of the turbine 5 can be that the turbine 5 rotates forward for several circles first, and then rotates backward for several circles, alternating and cycling multiple times, but it is not limited to this.

[0100] In this embodiment, the sequence of the forward and backward rotation directions of the turbine 5, as well as the number of circles and time of each rotation are not specifically limited, and those skilled in the art can set them according to actual needs.

[0101] For example, when controlling the hot water cleaning component 4 to inject hot water into the turbine 5, the turbine 5 can rotate clockwise for 3 seconds, and then rotate counterclockwise for 3 seconds, alternating and cycling multiple times, but it is not limited to this.

[0102] At the same time, when the turbine 5 rotates at the second rotation speed, the second rotation speed can be set to be greater than the first rotation speed, that is, when controlling the hot water cleaning component 4 to inject hot water into the turbine 5, the turbine 5 rotates quickly to shake off the oil stains softened by the steam.

[0103] Among them, the second rotation speed can be set to 10 circles per second, but it is not limited to this.

[0104] Optionally, after the steps of controlling the steam cleaning component 3 to inject steam into the turbine 5 and controlling the hot water cleaning component 4 to inject hot water into the turbine 5 are cyclically executed a preset number of times, stop injecting steam and hot water into the turbine 5.

[0105] Specifically, controlling the steam cleaning component 3 to inject steam into the turbine 5 and controlling the hot water cleaning component 4 to inject hot water into the turbine 5 can be alternated, that is, the steam cleaning component 3 and the hot water cleaning component 4 alternately inject steam and hot water into the turbine 5 to ensure the cleaning efficiency of the turbine 5.

[0106] For example, when the hot water cleaning component 4 includes a water pump 40 arranged on the steam cleaning pipeline 31, the steam generator 13 can be controlled to alternately generate hot water and steam, and then the water pump 40 is used to alternately inject steam and hot water into the turbine 5.

[0107] Furthermore, after the steps of controlling the steam cleaning component 3 to inject steam into the turbine 5 and controlling the hot water cleaning component 4 to inject hot water into the turbine 5 are alternately cycled and the number of cycles reaches the preset number, the steam cleaning component 3 and the hot water cleaning component 4 can be closed, for example, the water pump 40 and the steam generator 13 are closed to stop injecting steam and hot water into the turbine 5.

[0108] Among them, the preset number can be set to 3 times, but it is not limited to this, and those skilled in the art can set it according to actual needs.

[0109] Optionally, after stopping the injection of steam and hot water into the turbine 5, the method further comprises:

[0110] The turbine 5 is controlled to rotate so that the turbine 5 is spun dry.

[0111] Specifically, after the injection of steam and hot water into the turbine 5 is stopped, the turbine 5 may be controlled to rotate at a third speed, thereby performing surface air drying.

[0112] Among them, the third speed can be set to a faster speed to improve the spin-drying efficiency. For example, the third speed is set to be greater than the first speed. Those skilled in the art can set it according to actual needs.

[0113] Furthermore, after stopping injecting steam and hot water into the turbine 5 , the time for the turbine 5 to rotate at the third speed can also be set according to actual needs. For example, the turbine 5 is controlled to rotate at the third speed for 10 minutes to ensure that the turbine 5 is dried.

[0114] Meanwhile, when the turbine 5 rotates at the third speed, it may rotate clockwise or counterclockwise. The embodiment of the present invention does not limit the rotation direction of the turbine 5 .

[0115] Figure 8 A flow chart of another self-cleaning control method for an integrated stove provided by an embodiment of the present invention is shown as follows: Figure 8 As shown, for example, during the process of the steam cleaning pipeline 31 injecting steam into the turbine 5, the turbine 5 is set to rotate at a first speed for 5 minutes, so that the steam can fully soften the oil stains on the turbine 5. Then, the spray head 44 is controlled to spray hot water to the turbine 5, and the turbine 5 is controlled to rotate alternately in forward and reverse directions, so that the hot water can fully contact the turbine 5 to wash the oil stains. After the number of cycles of the steam cleaning pipeline 31 injecting steam into the turbine 5 and the spray head 44 spraying hot water to the turbine 5 reaches a preset number, the steam cleaning component 3 and the hot water cleaning component 4 are turned off, and the turbine 5 is controlled to rotate quickly for 10 minutes for drying, so as to avoid the oily waste liquid from remaining on the surface of the turbine 5 and affecting the normal operation of the range hood 2, thereby improving the reliability of the range hood 2.

A humidity sensor 32 is arranged on the steam cleaning pipeline 31.

[0118] It should be noted that the integrated stove provided by the embodiment of the present invention is not limited to the above structure, and those skilled in the art can set the structures of each component of the integrated stove according to actual needs.

[0119] As Figure 3 shown, optionally, the range hood 2 further includes a steam pipeline interface 21 and a hot water pipeline interface 22. The steam pipeline interface 21 can be used to extend the steam cleaning pipeline 31 to the turbine 5 of the range hood 2; the hot water pipeline interface 22 can be used to extend the hot water cleaning component 4 to the turbine 5 of the range hood 2.
