[0070] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0071] Example 1

[0072] like Figure 1-5 As shown, this embodiment provides a stove 100 , which includes: a stopcock 130 , a burner 140 , a flame control valve 150 , an inner ring air duct 110 and an outer ring air duct 120 .

[0080] 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.

[0081] The fire control valve 150 further includes a middle adjustment nail 176 and an inner adjustment nail 166. The middle adjustment nail 176 is disposed in the middle interception channel and is used to adjust the flow of the middle interception channel. The inner adjustment nail 166 is disposed in the inner interception channel 165 and is used to adjust the flow of the inner interception channel 165. By providing the adjustment nails, interception of the interception channel is achieved.

[0082] A middle flow cut-off hole 177 is provided in the middle flow adjustment nail 176 , and the middle flow cut-off hole 177 is connected to the side wall and the end surface of the middle flow adjustment nail 176 respectively.

[0083] An inner intercepting hole 167 is provided in the inner adjusting nail 166 , and the inner intercepting hole 167 is connected to the side wall and the end surface of the inner adjusting nail 166 respectively.

[0084] The interception of the interception channel is achieved through the interception hole in the interception nail.

[0085] The shell 151 is also provided with a middle flow interception mounting hole 178 and an inner flow interception mounting hole 168 which penetrate from the outside of the shell 151 to the inside of the shell 151, the middle flow adjustment nail 176 is installed in the middle flow interception mounting hole 178, the inner adjustment nail 166 is installed in the inner flow interception mounting hole 168, the middle flow interception mounting hole 178 penetrates the middle flow interception channel, and the inner flow interception mounting hole 168 penetrates the inner flow interception channel 165.

[0086] The middle flow cutoff mounting hole 178 and the inner flow cutoff mounting hole 168 are adjacent to each other.

[0087] The inner ring channel and the outer ring channel are arranged in a first direction, and the middle flow interception mounting hole 178 and the inner flow interception mounting hole 168 are arranged in a second direction perpendicular to the first direction.

[0088] The middle intercepting channel includes a middle inclined channel 1751 and a middle transverse channel 1752 which are interconnected.

[0089] The middle inclined channel 1751 is connected to the upstream side of the inner solenoid valve 153 in the inner ring channel, and the middle transverse channel 1752 is connected to the upstream side of the outer solenoid valve 152 in the outer ring channel.

[0090] The middle transverse channel 1752 extends along the first direction and is adjacent to the inner ring channel and the outer ring channel.

[0091] 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.

[0092] The adjusting nail is threadedly connected in the shutoff installation hole.

[0093] The regulating pin mainly realizes flow interception through the interception hole. The cross-sectional area of ​​the interception hole is much smaller than the cross-sectional area of ​​the normal fluid channel such as the inner ring channel, the outer ring channel, the outer interception channel 185, the inner interception channel 165, etc., and only a small amount of fluid can flow through the interception hole.

[0094] A portion of the shutoff hole penetrates the side wall of the adjusting pin, and the shutoff hole forms a "T" shape in the adjusting pin, including a transverse penetrating portion and a longitudinal penetrating portion. The diameter of the adjusting pin where the transverse penetrating portion is located is smaller than the diameter of the shutoff mounting hole where the adjusting pin is located at the corresponding position, so that at this position, a gap is formed between the side of the adjusting pin and the hole wall of the shutoff mounting hole, so that the fluid entering from the shutoff channel can pass through the gap and enter the shutoff hole of the adjusting pin, thereby connecting the upstream side and the downstream side of the solenoid valve of the ring channel, but only allowing a trace amount of fluid to flow.

[0095] 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.

[0096] The inner ring channel includes a first inner ring cavity 162 and a second inner ring cavity 163 which are continuously arranged. The second inner ring cavity 163 is provided with an inner ring valve seat 164. The valve plug of the inner solenoid valve 153 is arranged in the first inner ring cavity 162 and abuts against the inner ring valve seat 164 to cut off the connection between the first inner ring cavity 162 and the second inner ring cavity 163.

[0097] The outer ring channel includes a first outer ring cavity 182 and a second outer ring cavity 183 which are continuously arranged. The second outer ring cavity 183 is provided with an outer ring valve seat 184. The valve plug of the outer solenoid valve 152 is arranged in the first outer ring cavity 182 and abuts against the outer ring valve seat 184 to cut off the connection between the first outer ring cavity 182 and the second outer ring cavity 183.

[0098] One end and the other end of the inner intercepting channel 165 are respectively connected to the first inner ring cavity 162 and the second inner ring cavity 163; one end and the other end of the middle intercepting channel are respectively connected to the first outer ring cavity 182 and the second outer ring cavity 183; one end and the other end of the middle intercepting channel are respectively connected to the first inner ring cavity 162 and the first outer ring cavity 182.

[0099] The first inner ring cavity 162 is connected to the air inlet end of the inner ring air passage 110 through the inner ring air inlet 101, and the second inner ring cavity 163 is connected to the air outlet end of the inner ring air passage 110 through the inner ring air outlet 102;

[0100] The first outer ring cavity 182 is connected to the air inlet end of the outer ring air passage 120 through the outer ring air inlet 103, and the second outer ring cavity 183 is connected to the air outlet end of the outer ring air passage 120 through the outer ring air outlet 104;

[0101] The axes of the inner ring air inlet 101 , the inner ring air outlet 102 , the outer ring air inlet 103 and the outer ring air outlet 104 are all on the same plane.

[0102] When the outer solenoid valve 152 opens the outer ring channel, the fluid in the outer ring channel flows normally. At the same time, since one end and the other end of the middle interception channel are respectively connected to the first inner ring cavity 162 and the first outer ring cavity 182, the gas entering from the inner ring air intake pipe will supplement the gas in the outer ring channel in a small amount through the middle interception channel.

[0103] When the outer solenoid valve 152 closes the outer ring passage, the outer ring passage is closed.

[0104] When the inner solenoid valve 153 opens the inner ring channel, the fluid in the inner ring channel circulates normally, and at the same time, since one end and the other end of the middle interception channel are respectively connected to the first inner ring cavity 162 and the first outer ring cavity 182, the gas entering from the outer ring air inlet pipe will supplement the gas in the inner ring channel in a small amount through the middle interception channel.

[0105] When the inner solenoid valve 153 closes the inner ring channel, the upstream side and the downstream side of the inner solenoid valve 153 of the inner ring channel, i.e., the first inner ring cavity 162 and the second inner ring cavity 163 are connected through the inner intercepting channel 165 and only a trace amount of fluid is allowed to pass through.

[0106] When the flame control valve 150 is used to adjust the flame of the cooker 100, the following flame adjustment modes are provided:

[0107] Mode 1: When the inner solenoid valve 153 is opened and the outer solenoid valve 152 is opened, the plug valve 130 rotates to have an inner ring fire and an outer ring fire (corresponding to state A), and the fire control valve 150 has no adjustment for the firepower of the burner 140 (the firepower is adjusted as the plug valve 130 rotates); when the inner solenoid valve 153 is opened and the outer solenoid valve 152 is opened, the plug valve 130 rotates to close the outer ring fire and has only an inner ring fire (corresponding to state B), the fire control valve 150 has no adjustment for the inner ring fire of the burner 140 (the firepower is adjusted as the plug valve 130 rotates), but the outer ring fire of the burner 140 will maintain a medium fire or a low fire (the middle interception channel has a trace amount of fluid flowing, and the size of the firepower depends on the selection of the interception hole).

[0108] Mode 2: When the inner solenoid valve 153 is closed and the outer solenoid valve 152 is closed, 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 (a small amount of fluid flows through the inner shut-off channel 165), and the outer ring fire is out of fire; when the inner solenoid valve 153 is closed and the outer solenoid valve 152 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 is out of fire.

[0109] Mode three: when the inner solenoid valve 153 is opened and the outer solenoid valve 152 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 remains without fire; when the inner solenoid valve 153 is opened and the outer solenoid valve 152 is closed, the plug valve 130 is in state B, the fire control valve 150 does not adjust the firepower of the burner 140 (the firepower is adjusted with the rotation of the plug valve 130).

[0110] Mode 4: When the inner solenoid valve 153 is closed and the outer solenoid valve 152 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 153 is closed and the outer solenoid valve 152 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 medium or low fire (the middle interception channel has a trace amount of fluid flowing, and the size of the firepower depends on the selection of the interception hole).

[0111] 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).

[0112] 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.

[0113] Through the mode 1 and mode 4 of the fire control valve 150, the fire power can be increased even after the stopcock valve 130 cuts off the flow, and the temperature control function is more complete.

[0114] 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.

[0115] In mode one and mode four, that is, when the plug valve 130 itself has closed the outer ring fire, the outer ring fire still exists. Therefore, in order to adjust the fire normally outside the mode, an angle micro switch can be added to the valve body of the plug valve 130 to identify these two states (when both the inner ring fire and the outer ring fire are available, the angle range of the plug valve 130 is 0-120°) (when only the inner ring fire is available without the outer ring, the angle range of the plug valve 130 is 120-170°). For example, a 120-170° angle detection can be added so that the user can identify the critical closing angle of the outer ring fire when the fire control valve 150 is not adjusted during normal use.

[0116] Example 2

[0117] like Figure 6-9 As shown, embodiment 2 provides a fire control valve 250. The fire control valve 250 of embodiment 2 is substantially the same as the fire control valve 150 of embodiment 1, except that:

[0118] An external intercepting channel 185 is also provided in the shell 151 , and one end and the other end of the external intercepting channel 185 are respectively connected to the upstream side and the downstream side of the external solenoid valve 152 in the outer ring channel.

[0119] The fire control valve 150 further includes an external adjustment pin 186 , which is disposed in the external shutoff passage 185 and is used to adjust the flow of the external shutoff passage 185 .

[0120] The outer adjusting pin 186 is provided with an outer intercepting hole 187, and the outer intercepting hole 187 is respectively connected to the side wall and the end surface of the outer adjusting pin.

[0121] The shell 151 is also provided with an external interception mounting hole 188 penetrating from the outside of the shell 151 to the inside of the shell 151 , and the external adjustment nail 186 is installed in the external interception mounting hole 188 , and the external interception mounting hole 188 penetrates the external interception channel 185 .

[0122] The outer interception channel 185 includes an outer inclined channel and an outer vertical channel which are interconnected. One end of the outer inclined channel is connected to the outer interception mounting hole 188, and the other end of the outer inclined channel is connected to the first outer ring cavity 182. One end of the outer vertical channel is connected to the outer interception mounting hole 188, and the other end of the outer vertical channel is connected to the second outer ring cavity 183.

[0123] When the outer solenoid valve 152 opens the outer ring channel, the fluid in the outer ring channel flows normally. At the same time, since one end and the other end of the middle interception channel are respectively connected to the first inner ring cavity 162 and the first outer ring cavity 182, the gas entering from the inner ring air intake pipe will supplement the gas in the outer ring channel in a small amount through the middle interception channel.

[0124] When the outer solenoid valve 152 closes the outer ring channel, the upstream side and the downstream side of the outer solenoid valve 152 of the outer ring channel, i.e., the first outer ring cavity 182 and the second outer ring cavity 183 are connected through the outer intercepting channel 185 and only a trace amount of fluid is allowed to pass through.

[0125] When the inner solenoid valve 153 opens the inner ring channel, the fluid in the inner ring channel circulates normally, and at the same time, since one end and the other end of the middle interception channel are respectively connected to the first inner ring cavity 162 and the first outer ring cavity 182, the gas entering from the outer ring air inlet pipe will supplement the gas in the inner ring channel in a small amount through the middle interception channel.

[0126] When the inner solenoid valve 153 closes the inner ring channel, the upstream side and the downstream side of the inner solenoid valve 153 of the inner ring channel, i.e., the first inner ring cavity 162 and the second inner ring cavity 163 are connected through the inner intercepting channel 165 and only a trace amount of fluid is allowed to pass through.

[0127] When the flame control valve 150 is used to adjust the flame of the cooker 100, the following flame adjustment modes are provided:

[0128] Mode 1: When the inner solenoid valve 153 is opened and the outer solenoid valve 152 is opened, the plug valve 130 rotates to have an inner ring fire and an outer ring fire (corresponding to state A), and the fire control valve 150 does not adjust the firepower of the burner 140 (the firepower is adjusted as the plug valve 130 rotates); when the inner solenoid valve 153 is opened and the outer solenoid valve 152 is opened, the plug valve 130 rotates to close the outer ring fire and has only an inner ring fire (corresponding to state B), the fire control valve 150 does not adjust the inner ring fire of the burner 140 (the firepower is adjusted as the plug valve 130 rotates), but the outer ring fire of the burner 140 will maintain a medium fire (the middle interception channel and the outer interception channel 185 both provide gas for the outer ring fire to keep it at a medium fire).

[0129] Mode 2: When the inner solenoid valve 153 is closed and the outer solenoid valve 152 is closed, 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 (the inner shut-off channel 165 has a trace amount of fluid flowing), and the outer ring fire keeps a low fire (the outer shut-off channel 185 has a trace amount of fluid flowing); when the inner solenoid valve 153 is closed and the outer solenoid valve 152 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, and the outer ring fire keeps a low fire (the outer shut-off channel 185 has a trace amount of fluid flowing).

[0130] Mode three: when the inner solenoid valve 153 is opened and the outer solenoid valve 152 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 (the outer shut-off channel 185 has a trace amount of fluid flowing); when the inner solenoid valve 153 is opened and the outer solenoid valve 152 is closed, the plug valve 130 is in state B, the fire control valve 150 does not adjust the inner ring fire of the burner 140 (the firepower is adjusted with the rotation of the plug valve 130), and the outer ring fire is kept at a low fire (the outer shut-off channel 185 has a trace amount of fluid flowing).

[0131] Mode four: when the inner solenoid valve 153 is closed and the outer solenoid valve 152 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 at a normal fire (the firepower is adjusted with the rotation of the plug valve 130); when the inner solenoid valve 153 is closed and the outer solenoid valve 152 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 at a medium fire (the middle interception channel and the outer interception channel 185 both provide fuel gas for the outer ring fire to keep it at a medium fire).

[0132] 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).

[0133] 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.

[0134] Although the fire control valve 150 of this embodiment cannot close the outer ring fire alone, it can provide a variety of flame states and provide more firepower change options.
