[0074] The plug valve 110 is connected to the burner 120 through the inner ring gas passage 130 and provides gas to the inner ring fire cover of the burner 120 . The plug valve 110 is connected to the burner 120 through the outer ring gas passage 140 and provides gas to the outer ring fire cover of the burner 120 .

[0075] The fire control valve 150 is disposed between the stopcock 110 and the burner 120 and forms a part of the passage of the inner ring air passage 130 and the outer ring air passage 140 . The opening and closing of the inner ring air passage 130 and the outer ring air passage 140 are controlled by the fire control valve 150 .

[0076] The fire control valve 150 includes a housing 151 , an outer solenoid valve 152 and an inner solenoid valve 153 .

[0077] An outer ring channel, an inner ring channel, an inner intercepting channel and a middle intercepting channel are arranged in the shell 151 .

[0078] The outer solenoid valve 152 is disposed in the outer ring channel and is used to open and close the outer ring channel, and the inner solenoid valve 153 is disposed in the inner ring channel and is used to open and close the inner ring channel.

[0079] The outer ring channel is connected to the outer ring air channel 140, and the inner ring channel is connected to the inner ring air channel 130; the first end and the second end of the inner cut-off channel are respectively connected to the upstream side and the downstream side of the inner solenoid valve 153 of the inner ring channel; the first end and the second end of the middle cut-off channel are respectively connected to the upstream side of the inner solenoid valve 153 of the inner ring channel and the upstream side of the outer solenoid valve 152 of the outer ring channel.

[0080] The first end of the inner intercepting channel and the first end of the middle intercepting channel are the same port.

[0081] The stove is equipped with a fire control valve between the stopcock and the burner, so that different fire powers can be adjusted according to different cooking scenarios, with more fire adjustment states and more intelligent fire adjustment.

[0082] The fire control valve 150 further includes an adjusting pin 210, which is disposed in both the inner interception channel and the middle interception channel and is used to adjust the flow of the inner interception channel and the flow of the middle adjustment channel.

[0083] By arranging an adjusting pin in the intercepting channel, intercepting the intercepting channel can be easily achieved.

[0084] A cut-off passage is provided inside the adjusting nail 210, and the cut-off passage has an air inlet port 214, an inner ring air outlet port 215 and an outer ring air outlet port 216.

[0085] The intercepting passage includes vertical holes and horizontal holes which penetrate each other vertically.

[0086] The horizontal hole passes through the adjustment pin 210 laterally, and the two ends of the horizontal hole are air inlet ports 214. The vertical hole extends vertically in the adjustment pin 210 and passes through the end face of the adjustment pin 210. The port through which the vertical hole passes through the end face is the inner ring air outlet port 215. The outer ring air outlet port 216 is formed on the side of the adjustment pin 210 and is located on the opposite side of the inner ring air outlet port 215 relative to the horizontal hole. The vertical hole is connected to the outer ring air outlet port 216.

[0087] exist Figure 4 In the embodiment, the outer ring gas outlet port 216 is located above the horizontal hole.

[0088] In this embodiment, the intercepting channel is formed by setting an adjusting pin, but the present invention is not limited thereto, and those skilled in the art can form the intercepting channel by other existing components or other existing forms as needed.

[0089] The regulating pin 210 mainly realizes interception through the interception passage. The cross-sectional area of ​​the interception passage is much smaller than the cross-sectional area of ​​normal fluid channels such as the inner ring channel, the outer ring channel, the outer interception channel, the inner interception channel, etc. Only a small amount of fluid can flow through the interception passage.

[0090] The housing 151 is also provided with a flow interception installation hole 182 that penetrates from the outside of the housing 151 to the inside of the housing 151. The adjustment nail 210 is installed in the flow interception installation hole 182. The flow interception installation hole 182 penetrates the inner flow interception channel and the middle flow interception channel. The adjustment nail 210 is threadedly connected to the flow interception installation hole 182, and a sealing ring is also provided between the adjustment nail 210 and the flow interception installation hole 182.

[0091] The inner interception channel includes a transverse channel 181 and an interception mounting hole 182 . The interception mounting hole 182 penetrates the inner ring channel. The transverse channel 181 communicates with the upstream side of the inner solenoid valve 153 in the inner ring channel and the interception mounting hole 182 .

[0092] The middle intercepting channel includes a transverse channel 181, an intercepting installation hole 182, and an inclined channel 191. The inclined channel 191 extends from the intercepting installation hole 182 to the upstream side of the outer solenoid valve 152 in the outer ring channel. Figure 4 In the embodiment, the left end of the inclined channel 191 is located above the transverse channel 181 , thereby docking with the outer ring air outlet port 216 in the adjustment nail 210 .

[0093] The inner ring channel includes a first inner ring cavity 161 and a second inner ring cavity 162 which are arranged continuously. The second inner ring cavity 162 is provided with an inner ring valve seat. The valve plug of the inner solenoid valve 153 is arranged in the first inner ring cavity 161 and abuts against the inner ring valve seat to cut off the communication between the first inner ring cavity 161 and the second inner ring cavity 162.

[0094] The outer ring channel includes a first outer ring cavity 171 and a second outer ring cavity 172 which are continuously arranged. The second outer ring cavity 172 is provided with an outer ring valve seat. The valve plug of the outer solenoid valve 152 is arranged in the first outer ring cavity 171 and abuts against the outer ring valve seat to cut off the connection between the first outer ring cavity 171 and the second outer ring cavity 172.

[0095] The first inner ring cavity 161 is connected to the air inlet end of the inner ring air passage 130 through the inner ring air inlet 221, and the second inner ring cavity 162 is connected to the air outlet end of the inner ring air passage 130 through the inner ring air outlet;

[0096] The first outer ring cavity 171 is connected to the air inlet end of the outer ring air channel 140 through the outer ring air inlet, and the second outer ring cavity 172 is connected to the air outlet end of the outer ring air channel 140 through the outer ring air outlet;

[0097] The axes of the inner ring air inlet 221 , the inner ring air outlet, the outer ring air inlet and the outer ring air outlet are all on the same plane.

[0098] When the outer solenoid valve opens the outer ring channel, the fluid in the outer ring channel circulates normally.

[0099] When the outer solenoid valve closes the outer ring channel, no fluid flows through the outer ring channel.

[0100] When the inner solenoid valve opens the inner ring channel, the fluid in the inner ring channel circulates normally.

[0101] When the inner solenoid valve 153 closes the inner ring channel, the upstream side and downstream side of the inner solenoid valve 153 in the inner ring channel, i.e., the first inner ring cavity and the second inner ring cavity are connected through the inner shut-off channel, and at the same time, the gas on the upstream side (first outer ring cavity) of the outer solenoid valve in the outer ring channel is supplied to the downstream side (second inner ring cavity) of the inner solenoid valve in the inner ring channel through the middle shut-off channel.

[0102] When the flame control valve is used to adjust the flame of the cooker, the following flame adjustment modes are available:

[0103] Mode 1: When the inner solenoid valve 153 is opened and the outer solenoid valve 152 is opened, the plug valve 110 rotates to have inner ring fire and outer ring fire (corresponding to state A), and the fire control valve has no adjustment for the firepower of the burner (the firepower is adjusted as the plug valve rotates); when the inner solenoid valve is opened and the outer solenoid valve is opened, the plug valve rotates to close the outer ring fire and has only the inner ring fire (corresponding to state B), the fire control valve has no adjustment for the inner ring fire of the burner (the firepower is adjusted as the plug valve rotates), and the outer ring fire is kept at a low fire.

[0104] Mode 2: When the inner solenoid valve 153 is closed and the outer solenoid valve 152 is closed, the plug valve 110 is in state A, the fire control valve 150 makes the outer ring fire of the burner 120 extinguish and the inner ring fire maintains a low fire (at this time, only the inner shut-off channel has gas passing through, so that the inner ring fire maintains a low fire); when the inner solenoid valve is closed and the outer solenoid valve is closed, the plug valve 110 is in state B, the fire control valve 150 makes the inner ring fire of the burner 120 maintain a low fire, but the outer ring fire remains extinguished.

[0105] Mode three: when the inner solenoid valve 153 is open and the outer solenoid valve 152 is closed, the plug valve 110 is in state A, the fire control valve 150 keeps the inner ring fire normal (the firepower is adjusted with the rotation of the plug valve 110), and the outer ring fire has no fire; when the inner solenoid valve is open and the outer solenoid valve is closed, the plug valve is in state B, the fire control valve does not adjust the firepower of the burner 120.

[0106] Mode four: when the inner solenoid valve 153 is closed and the outer solenoid valve 152 is opened, and the plug valve 110 is in state A, the fire control valve 150 keeps the inner ring fire of the burner 120 at a low fire, and the outer ring fire remains normal (the firepower is adjusted with the rotation of the plug valve 110); when the inner solenoid valve is closed and the outer solenoid valve is opened, and the plug valve is in state B, the fire control valve 150 keeps the inner ring fire of the burner 120 at a low fire, and the outer ring fire remains at a low fire.

[0107] The fire control valve 150 keeps the inner ring fire of the burner 120 at a low fire and the outer ring fire at a low fire, keeps the inner ring fire at a low fire and the outer ring fire at no fire, or keeps the inner ring fire at a low fire and the outer ring fire at normal levels. All of these can reduce the firepower and reduce the interference of the inner ring fire on the anti-dry burning temperature sensing probe. This situation is suitable for cooking scenarios such as low-temperature frying (uniform low fire) or stewing soup (extremely low fire).

[0108] The fire control valve 150 can reduce the firepower by making the inner ring fire of the burner 120 remain normal and the outer ring fire remain without fire, or by making the inner ring fire remain normal and the outer ring fire remain at a low fire. This situation can be applied to temperature control scenarios to provide more firepower change options.

[0109] The operation of the fire control valve 150 (the opening and closing operation of the inner solenoid valve 153 and the outer solenoid valve 152) can be automatically executed through a set program, or manually executed through an externally set command switch. For example, buttons corresponding to different cooking scenes can be set on the stove 100. When it is necessary to make soup, the corresponding button is triggered to make the fire control valve 150 perform the operation corresponding to the cooking scene.

[0110] Example 2

The second inclined channel 312 connects the interception mounting hole 182 and the downstream side of the inner solenoid valve 153 in the inner ring channel.

[0113] The middle intercepting channel includes a first inclined channel 311 , an intercepting mounting hole 182 and a transverse channel 181 . The transverse channel 181 extends from the intercepting mounting hole 182 to the upstream side of the outer solenoid valve 152 in the outer ring channel.

[0114] In this embodiment, the interception mounting hole 182 does not penetrate the inner ring channel, but a second inclined channel 312 is additionally provided to provide an inner interception channel. At the same time, the channel in the middle interception channel leading to the first inner ring cavity 161 is formed horizontally, so as to be more convenient to manufacture.

[0115] Along the extending direction of the interception mounting hole 182 , the air inlet port 214 is disposed between the inner ring air outlet port 215 and the outer ring air outlet port 216 .

[0116] The intercepting passage includes a vertical hole and a horizontal hole which penetrate each other perpendicularly; the horizontal hole penetrates the adjusting nail 210 transversely, and both ends of the horizontal hole are air inlet ports 214; the vertical hole extends vertically in the adjusting nail 210 and penetrates the end face of the adjusting nail 210; the port through which the vertical hole penetrates the end face is the outer ring air outlet port 216; the inner ring air outlet port 215 is formed on the side of the adjusting nail 210 and is located on the opposite side of the inner ring air outlet port 215 relative to the horizontal hole; the vertical hole is connected to the inner ring air outlet port 215.
