[0077] In the embodiment, the adjusting pin 1551 is arranged to form the cut-off channel, but the utility model is not limited thereto, and those skilled in the art can form the cut-off channel by other existing components or other existing forms according to the needs.

[0078] The regulating pin 1551 mainly achieves the interception through the interception hole 1552, the interception hole 1552 has a much smaller cross-sectional area than that of the normal fluid channel, such as the inner ring channel 153, the outer ring channel 154, the outer interception channel, the inner interception channel, etc., and only a small amount of fluid can flow through the interception hole 1552.

[0079] The inner ring channel 153 includes an inner ring inner cavity 1532 and an inner ring outer cavity 1531 arranged in sequence, the inner ring inner cavity 1532 is provided with an inner ring valve seat, and the valve plug of the inner ring electromagnetic valve 161 is arranged in the inner ring outer cavity 1531 and abuts against the inner ring valve seat to cut off the communication between the inner ring inner cavity 1532 and the inner ring outer cavity 1531.

[0080] The outer ring channel 154 includes an outer ring inner cavity 1542 and an outer ring outer cavity 1541 arranged in sequence, the outer ring inner cavity 1542 is provided with an outer ring valve seat, and the valve plug of the outer ring electromagnetic valve 162 is arranged in the outer ring outer cavity 1541 and abuts against the outer ring valve seat to cut off the communication between the outer ring inner cavity 1542 and the outer ring outer cavity 1541.

[0081] The outer ring inner cavity 1542 is adjacent to the inner ring inner cavity 1532, the outer ring outer cavity 1541 is adjacent to the inner ring outer cavity 1531, and the inner ring inner cavity 1532 is arranged inside the inner ring outer cavity 1531, and the outer ring inner cavity 1542 is arranged inside the outer ring outer cavity 1541.

[0082] The outer ring inner cavity 1542 is separated from the inner ring inner cavity 1532 by a first partition wall, and the outer ring outer cavity 1541 is separated from the inner ring outer cavity 1531 by a second partition wall.

[0083] One end and the other end of the outer ring interception channel 155 are respectively communicated with the inner ring inner cavity 1532 and the outer ring outer cavity 1541.

[0084] The inner ring outer cavity 1531 is communicated with the gas inlet end of the inner ring air duct 130, and the inner ring inner cavity 1532 is communicated with the gas outlet end of the inner ring air duct 130; the outer ring outer cavity 1541 is communicated with the gas inlet end of the outer ring air duct 140, and the outer ring inner cavity 1542 is communicated with the gas outlet end of the outer ring air duct 140.

[0085] The inner ring outer cavity 1531 is communicated with the gas inlet end of the inner ring air duct 130 through the inner ring gas inlet 1561, and the inner ring inner cavity 1532 is communicated with the gas outlet end of the inner ring air duct 130 through the inner ring gas outlet 1562; the outer ring outer cavity 1541 is communicated with the gas inlet end of the outer ring air duct 140 through the outer ring gas inlet 1563, and the outer ring inner cavity 1542 is communicated with the gas outlet end of the outer ring air duct 140 through the outer ring gas outlet 1564; the axes of the inner ring gas inlet 1561, the inner ring gas outlet 1562, the outer ring gas inlet 1563 and the outer ring gas outlet 1564 are in the same plane.

[0086] The cooktop 100 also includes a control unit, which is electrically connected to the outer ring solenoid valve 162, the inner ring solenoid valve 161 and the micro switch 114.

[0087] The micro switch 114 is located inside the plug valve 110. It is activated when the plug valve 110 is rotated to the critical point of switching between the inner and outer rings and the inner ring, so that the micro switch 114 opens and closes the outer ring solenoid valve 162 at this time.

[0088] like Figure 5 As shown, the micro switch 114 includes an inclined paddle 115. A trigger plate 112 is sleeved on the valve stem 111 of the stopcock valve 110. The trigger plate 112 has a protrusion 113 extending a predetermined distance circumferentially along the trigger plate 112. The protruding length of the protrusion 113 is set to be able to press the paddle 115. When the paddle 115 is pressed, the micro switch 114 opens the outer ring solenoid valve 162. When the paddle 115 is not pressed, the micro switch 114 closes the outer ring solenoid valve 162.

[0089] In this embodiment, the rotation of the plug valve 110 from 0 to the maximum angle corresponds to the rotation from minimum flame to maximum flame and then back to minimum flame.

[0090] Taking a maximum rotation angle of 170° for the plug valve, 0-40° corresponds to only inner ring firing, 40°-140° corresponds to both inner and outer ring firing, and 140°-170° corresponds to only inner ring firing as an example, the coverage angle corresponding to the predetermined distance the protrusion 113 extends circumferentially along the trigger plate 112 is 100°. When the plug valve 110 rotates to 0-40°, the paddle 115 is not pressed, and the outer ring solenoid valve 162 is closed. When the plug valve 110 rotates to 40°-140°, the paddle 115 is pressed by the protrusion 113, and the outer ring solenoid valve 162 is normally opened. When the plug valve 110 rotates to 140°-170°, the paddle 115 is not pressed, causing the outer ring solenoid valve 162 to close. The protrusion 113 in the forward rotation direction ( Figure 5 The tail end of the stop valve 110 (clockwise direction) smoothly transitions with the rest of the trigger plate 112, so that the stop valve 110 rotates (in the clockwise direction). Figure 5 When rotating counterclockwise (in the middle), it can be turned smoothly.

[0091] In other embodiments, the micro switch includes an inclined paddle, and a trigger plate is sleeved on the valve stem of the plug valve. The trigger plate may also be provided with a first protrusion and a second protrusion extending a predetermined distance along the circumference of the trigger plate. The first protrusion and the second protrusion are separated by a predetermined distance in the circumferential direction, and the protrusion lengths of the first protrusion and the second protrusion are both set to be able to press the paddle.

[0092] The specified distance corresponds to the rotation angle range of the cock valve of the large fire, and the extension length of the first and second protrusions in the circumferential direction corresponds to the rotation angle range of the cock valve of the small fire.

[0093] Taking the maximum rotation angle of the cock valve as 170°, 0-40° corresponding to only the inner ring fire, 40°-140° corresponding to having both the inner and outer ring fires, and 140°-170° corresponding to only the inner ring fire, the circumferential extension coverage angles of the first and second protrusions are 40° and 30° respectively, and the circumferential extension coverage angle of the specified distance is 100°. When the cock valve is rotated to 0-40°, the first protrusion presses the tab, so that the outer ring electromagnetic valve is closed, when the cock valve is rotated to 40°-140°, the tab is not pressed, and the outer ring electromagnetic valve is normally opened, when the cock valve is rotated to 140°-170°, the second protrusion presses the tab, so that the outer ring electromagnetic valve is closed. The tail ends of the first and second protrusions in the forward rotation direction smoothly transition with other parts of the trigger plate, so that the cock valve can smoothly rotate when it is rotated back.

[0094] When the outer ring electromagnetic valve 162 opens the outer ring passage 154, the fluid in the outer ring passage 154 normally flows.

[0095] When the outer ring electromagnetic valve 162 closes the outer ring passage 154, the outer ring passage 154 is closed.

[0096] When the inner ring electromagnetic valve 161 opens the inner ring passage 153, the fluid in the inner ring passage 153 normally flows.

[0097] When the inner ring electromagnetic valve 161 closes the inner ring passage 153, the upstream side and the downstream side of the inner ring electromagnetic valve 161 of the inner ring passage 153, i.e. the inner ring outer chamber and the inner ring inner chamber, are connected through the outer ring cutoff passage 155 and only allow a small amount of fluid to pass.

[0098] When the fire control valve 150 is used to adjust the fire of the stove 100, the following fire adjustment modes are provided:

[0099] Mode One: When inner ring solenoid valve 161 is open and outer ring solenoid valve 162 is open, cock valve 110 is rotated to have both inner ring fire and outer ring fire (corresponding to A state), control fire valve 150 has no adjustment for the fire of burner 120 (the fire is adjusted with the rotation of cock valve 110); when inner ring solenoid valve 161 is open and outer ring solenoid valve 162 is open, cock valve 110 is rotated to have only inner ring fire with outer ring fire off (corresponding to B state), control fire valve 150 keeps the inner ring fire of burner 120 normal (the fire is adjusted with the rotation of cock valve 110), but keeps the outer ring fire as a small fire (at this time, the gas is supplied from the inner ring inner chamber to the outer ring outer chamber through outer ring cut-off passage 155, and then is supplied to the outer ring inner chamber through the open outer ring solenoid valve 162, so as to be supplied to the outer ring fire cover of burner 120).

[0100] Mode Two: When inner ring solenoid valve 161 is closed and outer ring solenoid valve 162 is closed, cock valve 110 is rotated to have both inner ring fire and outer ring fire (corresponding to A state), control fire valve 150 keeps the inner ring fire of burner 120 as a small fire (at this time, the gas is supplied from the outer ring outer chamber to the inner ring inner chamber through outer ring cut-off passage 155), and keeps the outer ring fire as no fire; when inner ring solenoid valve 161 is closed and outer ring solenoid valve 162 is closed, cock valve 110 is rotated to have only inner ring fire with outer ring fire off (corresponding to B state), control fire valve 150 keeps the inner ring fire of burner 120 as no fire, and keeps the outer ring fire as no fire.

[0101] Mode Three: When inner ring solenoid valve 161 is open and outer ring solenoid valve 162 is closed, cock valve 110 is rotated to have both inner ring fire and outer ring fire (corresponding to A state), control fire valve 150 keeps the inner ring fire of burner 120 normal (the fire is adjusted with the rotation of cock valve 110), and keeps the outer ring fire as no fire; when inner ring solenoid valve 161 is open and outer ring solenoid valve 162 is closed, cock valve 110 is rotated to have only inner ring fire with outer ring fire off (corresponding to B state), control fire valve 150 keeps the inner ring fire of burner 120 normal (the fire is adjusted with the rotation of cock valve 110), and keeps the outer ring fire as no fire.

[0102] Mode Four: When inner ring solenoid valve 161 is closed and outer ring solenoid valve 162 is open, cock valve 110 is rotated to have both inner ring fire and outer ring fire (corresponding to A state), control fire valve 150 keeps the inner ring fire of burner 120 as a small fire (at this time, the gas is supplied from the outer ring outer chamber to the inner ring inner chamber through outer ring cut-off passage 155), and keeps the outer ring fire as normal (the fire is adjusted with the rotation of cock valve 110); when inner ring solenoid valve 161 is closed and outer ring solenoid valve 162 is open, cock valve 110 is rotated to have only inner ring fire with outer ring fire off (corresponding to B state), control fire valve 150 keeps the inner ring fire of burner 120 as no fire, and keeps the outer ring fire as no fire.

[0103] The A state and B state of the modes one to four are respectively abbreviated as 1A, 2A, 3A, 4A and 1B, 2B, 3B, 4B.

[0104] 1A and 3B are the modes in normal operation of the user, that is, without using the fire control valve 150 to control the stove 100 for the second time, only relying on the operation of the cock valve 110.

[0105] And the modes of 2A, 3A, 4A are suitable for cooking modes such as temperature control and soup boiling, and the mode of 1B is suitable for temperature control. Intelligent temperature control can reduce the detection interference of dry burning prevention.

[0106] Since only 1A and 3B are the modes in normal operation of the user, when the fire control valve 150 is not needed to adjust the fire, the outer ring electromagnetic valve 162 needs to be automatically closed according to the rotation angle of the cock valve 110 to realize the normal operation mode.

[0107] In the embodiment, the micro switch 114 is provided, which can determine whether the cock valve 110 is rotated to the angle of only the inner ring fire. When the cock valve 110 is not operated, the outer ring electromagnetic valve 162 is kept closed, and the inner ring electromagnetic valve 161 is kept open. When the cock valve 110 is reversely rotated to the critical point of switching from the inner ring fire to the inner and outer ring fire, the outer ring electromagnetic valve 162 is opened, so as to automatically switch from the B mode to the A mode, realize the normal operation of the user, and close the outer ring electromagnetic valve 162.

[0108] The operation of the fire control valve 150 (the opening and closing operation of the inner electromagnetic valve and the outer electromagnetic valve) can be automatically executed through the set program or manually executed through the externally set instruction switch. For example, the keys corresponding to different cooking scenes can be set on the stove 100. When the soup is needed to be boiled, the corresponding key is triggered, so that the fire control valve 150 executes the operation corresponding to the cooking scene. It should be understood that the priority of the instruction switch corresponding to the cooking mode and the set program is higher than that of the micro switch 114. When the cooking mode is selected, the fire control valve 150 is no longer controlled through the micro switch 114.

[0109] In addition, in the states of 2B and 4B, the fire control valve 150 will make the stove 100 completely extinguish, therefore, in order to prevent the stove 100 from accidentally extinguishing, when the micro switch 114 is opened, the control unit controls the inner ring electromagnetic valve 161 to be kept open, and the priority of the control is the highest, and the set program and the instruction switch will also avoid the modes of 2B and 4B.

[0110] The fire control mode of the stove 100 of the utility model is more suitable for the burner 120 with a smaller inner ring.
