[0071] The stove 100 is provided with a fire control valve 150 between the stopcock 130 and the burner 140, so that different fire powers can be adjusted according to different cooking scenes, with more fire adjustment states and more intelligent fire adjustment.

[0073] By arranging the outer regulating nail and the inner regulating nail in the outer intercepting channel and the inner intercepting channel respectively, the outer intercepting channel and the inner intercepting channel can be conveniently formed.

[0074] An external intercepting hole 1707 is provided inside the external adjusting nail, and the external intercepting hole 1707 is respectively connected to the side wall and the end surface of the external adjusting nail.

[0075] An inner intercepting hole 1607 is provided in the inner adjusting nail, and the inner intercepting hole 1607 is respectively connected to the side wall and the end surface of the inner adjusting nail.

The diameter of the external adjusting pin where the transverse penetrating portion is located is smaller than the diameter of the external shut-off mounting hole 1705 where the external adjusting pin is located at the corresponding position, so that at this position, a gap is formed between the side of the external adjusting pin and the hole wall of the external shut-off mounting hole 1705, so that the fluid entering from the external shut-off channel can pass through the gap and enter the external shut-off hole 1707 of the external adjusting pin, thereby connecting the upstream side and the downstream side of the external solenoid valve 153 of the outer ring channel, but only allowing a trace amount of fluid to flow.

[0081] A portion of the inner shutoff hole 1607 penetrates the side wall of the inner adjusting pin, and the inner shutoff hole 1607 forms a "T" shape in the inner adjusting pin, including a transverse penetrating portion and a longitudinal penetrating portion. The diameter of the inner adjusting pin where the transverse penetrating portion is located is smaller than the diameter of the inner shutoff mounting hole 1605 where the inner adjusting pin is located at the corresponding position, so that at this position, a gap is formed between the side of the inner adjusting pin and the hole wall of the inner shutoff mounting hole 1605, so that the fluid entering from the inner shutoff channel can pass through the gap and enter the inner shutoff hole 1607 of the inner adjusting pin, thereby connecting the upstream side and the downstream side of the inner solenoid valve 152 of the inner ring channel, but only allowing a trace amount of fluid to flow.

[0082] 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.

[0083] The regulating pin mainly realizes interception through the interception hole. The cross-sectional area of ​​the interception hole 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 hole.

[0084] The inner ring channel includes a first inner ring cavity 1603 and a second inner ring cavity 1604 which are continuously arranged. The second inner ring cavity 1604 is provided with an inner ring valve seat 1608.

[0086] One end and the other end of the inner intercepting channel are respectively connected to the first inner ring cavity 1603 and the second inner ring cavity 1604; one end and the other end of the outer intercepting channel are respectively connected to the first outer ring cavity 1703 and the second outer ring cavity 1704.

[0087] The first inner ring cavity 1603 is connected to the air inlet end of the inner ring air passage 110 , and the second inner ring cavity 1604 is connected to the air outlet end of the inner ring air passage 110 .

[0088] The first outer ring cavity 1703 is connected to the air inlet end of the outer ring air channel 120 , and the second outer ring cavity 1704 is connected to the air outlet end of the outer ring air channel 120 .

[0089] The first inner ring cavity 1603 is connected to the air inlet end of the inner ring air channel 110 through the inner ring air inlet 1609 , and the second inner ring cavity 1604 is connected to the air outlet end of the inner ring air channel 110 through the inner ring air outlet 1610 .

[0091] The axes of the inner ring air inlet 1609 , the inner ring air outlet 1610 , the outer ring air inlet 1709 and the outer ring air outlet 1710 are all on the same plane.

[0092] The second inner ring cavity 1604 and the second outer ring cavity 1704 are adjacent to each other and are separated by a partition wall.

[0093] When the outer solenoid valve 153 opens the outer ring channel, the fluid in the outer ring channel circulates normally.

[0094] When the outer solenoid valve 153 closes the outer ring channel, the upstream side and the downstream side of the outer solenoid valve 153 of the outer ring channel, i.e., the first outer ring cavity 1703 and the second outer ring cavity 1704 are connected through the outer interception channel and only a trace amount of fluid is allowed to pass through.

[0095] When the inner solenoid valve 152 opens the inner ring passage, the fluid in the inner ring passage circulates normally.

[0096] When the inner solenoid valve 152 closes the inner ring channel, the upstream side and the downstream side of the inner solenoid valve 152 of the inner ring channel, i.e., the first inner ring cavity 1603 and the second inner ring cavity 1604 are connected through the inner intercepting channel and only a trace amount of fluid is allowed to pass through.

[0097] When the flame control valve 150 is used to adjust the flame of the cooker 100, the following flame adjustment modes are provided:

[0098] Mode 1: When the inner solenoid valve 152 is opened and the outer solenoid valve 153 is opened, the plug valve 130 rotates to have inner ring fire and outer ring fire (corresponding to state A), and the fire control valve 150 does not adjust the firepower of the burner 140; when the inner solenoid valve 152 is opened and the outer solenoid valve 153 is opened, the plug valve 130 rotates to have the outer ring fire closed and only have the inner ring fire (corresponding to state B), and the fire control valve 150 does not adjust the firepower of the burner 140.

[0099] Mode 2: When the inner solenoid valve 152 is closed and the outer solenoid valve 153 is closed, the plug valve 130 is in state A, the fire control valve 150 keeps the outer ring fire of the burner 140 at a low fire, and the inner ring fire at a low fire (at this time, only gas passes through the shut-off channel, so that the inner and outer rings keep a low fire); when the inner solenoid valve 152 is closed and the outer solenoid valve 153 is closed, the plug valve 130 is in state B, the fire control valve 150 keeps the inner ring fire of the burner 140 at a low fire, but the outer ring fire remains off.

[0100] Mode three: when the inner solenoid valve 152 is opened and the outer solenoid valve 153 is closed, the plug valve 130 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 130) and the outer ring fire is kept at a low fire; when the inner solenoid valve 152 is opened and the outer solenoid valve 153 is closed, the plug valve 130 is in state B, the fire control valve 150 does not adjust the firepower of the burner 140.

[0101] Mode four: when the inner solenoid valve 152 is closed and the outer solenoid valve 153 is opened, the plug valve 130 is in state A, the fire control valve 150 keeps the inner ring fire of the burner 140 at a low fire, and the outer ring fire remains normal (the firepower is adjusted with the rotation of the plug valve 130); when the inner solenoid valve 152 is closed and the outer solenoid valve 153 is opened, the plug valve 130 is in state B, the fire control valve 150 keeps the inner ring fire of the burner 140 at a low fire, and the outer ring fire remains off.

[0102] The fire control valve 150 keeps the inner ring fire of the burner 140 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 (even low fire) or stewing soup (extremely low fire).

[0103] The fire control valve 150 can reduce the firepower by making the inner ring fire of the burner 140 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.

[0104] The operation of the fire control valve 150 (the opening and closing operation of the inner solenoid valve 152 and the outer solenoid valve 153) 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 cook soup, the corresponding button is triggered to make the fire control valve 150 perform the operation corresponding to the cooking scene.
