Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a stove. Background Technology

[0002] Gas stoves are essential kitchen appliances in homes. Currently, the flame adjustment methods for gas stoves on the market include rotary valve adjustment, proportional valve adjustment, and motor valve adjustment, among which proportional valves and motor valves are more commonly used in the field of gas stove flame adjustment.

[0003] In existing technologies, conventional gas stoves using inner and outer ring burners and dual-channel plug valves face problems with high ignition adjustment costs when using electric control valves such as motor valves and proportional valves, and insufficient intelligence in ignition adjustment when using strong suction valves, as these offer too few ignition adjustment options for different scenarios. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which has too few flame adjustment states for different scenarios and is not intelligent enough in terms of flame adjustment, and to provide a stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0012] In this design, the stove features a flame control valve between the rotary valve and the burner, allowing for adjustments to the flame intensity based on different cooking scenarios.

[0070] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0071] like Figure 1-4 As shown, this embodiment provides a stove 100, which includes: a stop valve 110, a burner 120, a flame control valve 150, an inner ring gas passage 130 and an outer ring gas passage 140; the inner ring gas passage 130 and the outer ring gas passage 140 are connected between the stop valve 110 and the burner 120.

[0072] The plug valve 110 is connected to the burner 120 through the inner ring gas passage 130 and supplies gas to the inner ring burner cap of the burner 120. The plug valve 110 is also connected to the burner 120 through the outer ring gas passage 140 and supplies gas to the outer ring burner cap of the burner 120.

[0073] The flame control valve 150 is located between the plug valve 110 and the burner 120 and forms part of the passage of the inner ring gas passage 130 and the outer ring gas passage 140. The flame control valve 150 controls the opening and closing of the inner ring gas passage 130 and the outer ring gas passage 140.

[0074] like Figure 2-4 As shown, the fire control valve 150 includes: a housing 151, an outer ring solenoid valve 161, and an inner ring solenoid valve 162.

[0075] The housing 151 is provided with an outer ring channel 1531, an inner ring channel 1541, a first inner ring throttling channel 1551, and a second inner ring throttling channel 1561. An outer ring solenoid valve 161 is disposed in the outer ring channel 1531 and is used to open and close the outer ring channel 1531. An inner ring solenoid valve 162 is disposed in the inner ring channel 1541 and is used to open and close the inner ring channel 1541. The outer ring channel 1531 is connected to the outer ring air passage 140, and the inner ring channel 1541 is connected to the inner ring air passage 130. One end and the other end of the first inner ring throttling channel 1551 are respectively connected to the upstream side and the downstream side of the inner ring solenoid valve 162 in the inner ring channel 1541. One end and the other end of the second inner ring throttling channel 1561 are respectively connected to the downstream side of the inner ring solenoid valve 162 in the inner ring channel 1541 and the upstream side of the outer ring solenoid valve 161 in the outer ring channel 1531. Figure 3 The dashed lines indicate the gas flow direction in the inner ring channel 1541 and the outer ring channel 1531.

[0076] The cooktop 100 has a flame control valve 150 between the stopcock valve 110 and the burner 120, which allows for different firepower adjustments according to different cooking scenarios. This provides more firepower adjustment states and makes the firepower adjustment more intelligent. Furthermore, the flame control valve 150 can still adjust the firepower after controlling the firepower of the cooktop 100. When the stopcock valve 110 closes the outer ring gas passage 140, the low flame experience is excellent. It also has the states of inner ring low flame, outer ring low flame, and inner ring low flame with no flame on the outer ring.

[0077] The fire control valve 150 also includes a first inner ring adjusting pin and a second inner ring adjusting pin. The first inner ring adjusting pin is located in the first inner ring throttling channel 1551 and is used to adjust the flow rate of the first inner ring throttling channel 1551. The second inner ring adjusting pin is located in the second inner ring throttling channel 1561 and is used to adjust the flow rate of the second inner ring throttling channel 1561.

[0078] By setting a first inner ring adjusting pin and a second inner ring adjusting pin in the first inner ring intercepting channel 1551 and the second inner ring intercepting channel 1561 respectively, the interception of the first inner ring intercepting channel 1551 and the second inner ring intercepting channel 1561 can be easily achieved.

[0079] The first inner ring adjusting pin is provided with a first inner ring choke hole 1553, which is connected to the side wall and the end face of the first inner ring adjusting pin respectively; the second inner ring adjusting pin is provided with a second inner ring choke hole 1563, which is connected to the side wall and the end face of the second inner ring adjusting pin respectively.

[0080] The housing 151 is also provided with a first inner ring flow-blocking mounting hole 1556 and a second inner ring flow-blocking mounting hole 1566 extending from the outside of the housing 151 into the inside of the housing 151. The first inner ring adjusting pin is installed in the first inner ring flow-blocking mounting hole 1556, and the second inner ring adjusting pin is installed in the second inner ring flow-blocking mounting hole 1566. The first inner ring flow-blocking mounting hole 1556 extends through the first inner ring flow-blocking channel 1551, and the second inner ring flow-blocking mounting hole 1566 extends through the second inner ring flow-blocking channel 1561.

[0081] The first inner ring adjusting pin is threadedly connected to the first inner ring throttling mounting hole 1556, and the second inner ring adjusting pin is threadedly connected to the second inner ring throttling mounting hole 1566.

[0082] A portion of the first inner ring throttling hole 1553 penetrates the side wall of the first inner ring adjusting pin. The first inner ring throttling hole 1553 forms a "T" shape in the first inner ring adjusting pin, including a transverse through portion and a longitudinal through portion. The diameter of the first inner ring adjusting pin where the transverse through portion is located is smaller than the diameter of the first inner ring throttling mounting hole 1556 where the first inner ring adjusting pin is located at the corresponding position. This creates a gap between the side of the first inner ring adjusting pin and the hole wall of the first inner ring throttling mounting hole 1556 at that position. Fluid entering from the first inner ring throttling channel 1551 can pass through this gap and enter the first inner ring throttling hole 1553 of the first inner ring adjusting pin. This allows the upstream and downstream sides of the inner ring solenoid valve 162 of the inner ring channel 1541 to be connected, but only a small amount of fluid is allowed to flow.

[0083] A portion of the second inner ring choke hole 1563 penetrates the side wall of the second inner ring adjusting pin. The second inner ring choke hole 1563 forms a "T" shape in the second inner ring adjusting pin, including a transverse through portion and a longitudinal through portion. The diameter of the second inner ring adjusting pin where the transverse through portion is located is smaller than the diameter of the second inner ring choke mounting hole 1566 where the second inner ring adjusting pin is located at the corresponding position. This creates a gap between the side of the second inner ring adjusting pin and the hole wall of the second inner ring choke mounting hole 1566 at that position. Fluid entering from the second inner ring choke channel 1561 can pass through this gap and enter the second inner ring choke hole 1563 of the second inner ring adjusting pin. This allows the downstream side of the inner ring solenoid valve 162 of the inner ring channel 1541 and the upstream side of the outer ring solenoid valve 161 of the outer ring channel 1531 to communicate, but only a small amount of fluid is allowed to flow.

[0084] In this embodiment, an intercepting channel is formed by setting an adjusting pin. However, the present invention is not limited to this. Those skilled in the art can form an intercepting channel as needed using other existing components or other existing forms.

[0085] The regulating pin mainly achieves flow interception through the interception hole. The cross-sectional area of ​​the interception hole is much smaller than that of normal fluid channels such as inner ring channel 1541, outer ring channel 1531, outer interception channel, and inner interception channel. Only a small amount of fluid can flow through the interception hole.

[0086] The inner ring channel 1541 includes an inner ring inner cavity 1542 and an inner ring outer cavity 1543 continuously arranged. The inner ring inner cavity 1542 is provided with an inner ring valve seat. The valve plug of the inner ring solenoid valve 162 is disposed in the inner ring outer cavity 1543 and abuts against the inner ring valve seat to cut off the communication between the inner ring inner cavity 1542 and the inner ring outer cavity 1543. The outer ring channel 1531 includes an outer ring inner cavity 1532 and an outer ring outer cavity 1533 continuously arranged. The outer ring inner cavity 1532 is provided with an outer ring valve seat. The valve plug of the outer ring solenoid valve 161 is disposed in the outer ring outer cavity 1533 and abuts against the outer ring valve seat to cut off the communication between the outer ring inner cavity 1532 and the outer ring outer cavity 1533.

[0087] The inner ring inner cavity 1542 and the outer ring inner cavity 1532 are adjacent to each other and separated by a partition wall. The inner ring outer cavity 1543 and the outer ring outer cavity 1533 are also adjacent to each other and separated by a partition wall. The inner ring inner cavity 1542 is disposed inside the inner ring outer cavity 1543, and the outer ring inner cavity 1532 is disposed inside the outer ring outer cavity 1533.

[0088] One end of the first inner ring intercepting channel 1551 is connected to the inner ring outer cavity 1543 and the inner ring inner cavity 1542, respectively; one end of the second inner ring intercepting channel 1561 is connected to the inner ring inner cavity 1542 and the outer ring outer cavity 1533, respectively.

[0089] The diameter of the second inner ring intercepting hole 1563 is larger than the diameter of the first inner ring intercepting hole 1553.

[0090] The first inner ring throttling channel 1551 is mainly for maintaining the inner ring flame of the burner 120, while one of the functions of the second inner ring throttling channel 1561 is to maintain the outer ring flame of the burner 120 (see the explanation of the flame adjustment mode below). Since the flame coverage of the outer ring burner cap is larger, it usually requires more gas. Therefore, the diameter of the second inner ring throttling hole 1563 of the second inner ring throttling channel 1561 is larger than the diameter of the first inner ring throttling hole 1553 of the first inner ring throttling channel 1551. This ensures that the outer ring burner cap can maintain a small flame without extinguishing it, while the flame coverage of the inner ring burner cap is smaller, so a smaller throttling channel is used, making flame adjustment more precise.

[0091] The first inner ring interception mounting hole 1556 is located at a position corresponding to the inner ring cavity 1542, and the second inner ring interception mounting hole 1566 is located at a position corresponding to the outer ring cavity 1532.

[0092] The inner ring outer cavity 1543 is connected to the air inlet of the inner ring airway 130, and the inner ring inner cavity 1542 is connected to the air outlet of the inner ring airway 130; the outer ring outer cavity 1533 is connected to the air inlet of the outer ring airway 140, and the outer ring inner cavity 1532 is connected to the air outlet of the outer ring airway 140.

[0093] The first inner ring interception channel 1551 includes a first inclined channel 1554 and a vertical channel 1555 that are interconnected. The first inner inclined channel is connected to the outer cavity of the inner ring 1543, and the inner vertical channel 1555 is connected to the inner cavity of the inner ring 1542.

[0094] The second inner ring interception channel 1561 includes a second inclined channel 1564 and a third inclined channel 1565 that are interconnected. The second inclined channel 1564 is connected to the inner ring inner cavity 1542, and the third inclined channel 1565 is connected to the outer ring outer cavity 1533.

[0095] The inner ring outer cavity 1543 is connected to the air inlet of the inner ring air passage 130 through the inner ring air inlet 1571, and the inner ring inner cavity 1542 is connected to the air outlet of the inner ring air passage 130 through the inner ring air outlet 1572; the outer ring outer cavity 1533 is connected to the air inlet of the outer ring air passage 140 through the outer ring air inlet 1573, and the outer ring inner cavity 1532 is connected to the air outlet of the outer ring air passage 140 through the outer ring air outlet 1574; the axes of the inner ring air inlet 1571, the inner ring air outlet 1572, the outer ring air inlet 1573, and the outer ring air outlet 1574 are all on the same plane.

[0096] The cooktop 100 also includes a rotation detection unit and a control unit; the rotation detection unit is used to detect the rotation angle of the stopcock valve 110; the control unit is electrically connected to the rotation detection unit, the inner ring solenoid valve 162 and the outer ring solenoid valve 161; the control unit is used to control the opening and closing of the inner ring solenoid valve 162 and the outer ring solenoid valve 161 according to the detection result of the rotation detection unit.

[0097] When the outer ring solenoid valve 161 opens the outer ring channel 1531, the fluid in the outer ring channel 1531 flows normally.

[0098] When the outer ring solenoid valve 161 closes the outer ring channel 1531, the outer ring channel 1531 is closed.

[0099] When the inner ring solenoid valve 162 opens the inner ring channel 1541, the fluid in the inner ring channel 1541 flows normally.

[0100] When the inner ring solenoid valve 162 closes the inner ring channel 1541, the upstream and downstream sides of the inner ring solenoid valve 162 in the inner ring channel 1541, i.e., the outer inner ring chamber and the inner inner ring chamber, are connected through the first inner ring throttling channel 1551, allowing only a small amount of fluid to pass through. The downstream side of the inner ring solenoid valve 162 in the inner ring channel 1541 and the upstream side of the outer ring solenoid valve 161 in the outer ring channel 1531, i.e., the outer outer ring chamber and the inner inner ring chamber, are connected through the second inner ring throttling channel 1561, allowing only a small amount of fluid to pass through. At the same time, since the diameter of the second inner ring throttling orifice 1563 of the second inner ring throttling channel 1561 is larger than the diameter of the first inner ring throttling orifice 1553 of the first inner ring throttling channel 1551, the flow rate in the second inner ring throttling channel 1561 will be greater than the flow rate in the first inner ring throttling channel 1551.

[0101] When using the flame control valve 150 to adjust the flame of the stove 100, the following flame adjustment modes are available:

[0102] Mode 1: When the inner ring solenoid valve 162 is open and the outer ring solenoid valve 161 is open, the stopcock valve 110 rotates to have both inner and outer ring flames (corresponding to state A), and the flame control valve 150 does not adjust the flame of the burner 120; when the inner ring solenoid valve 162 is open and the outer ring solenoid valve 161 is open, the stopcock valve 110 rotates to have the outer ring flame closed and only the inner ring flame (corresponding to state B), and the flame control valve 150 keeps the inner ring flame of the burner 120 normal (the flame is adjusted with the rotation of the stopcock valve 110), but the outer ring flame remains low (at this time, the gas is supplied from the inner ring chamber to the outer ring chamber through the second inner ring throttling channel 1561, and then supplied to the outer ring chamber through the open outer ring solenoid valve 161, thereby being supplied to the outer ring burner cap of the burner 120).

[0103] Mode 2: When the inner ring solenoid valve 162 is closed and the outer ring solenoid valve 161 is closed, the stopcock valve 110 rotates to a state with both inner and outer ring flames (corresponding to state A). The flame control valve 150 keeps the inner ring flame of the burner 120 at a medium flame (at this time, gas is supplied from the inner ring outer chamber to the inner ring inner chamber through the first inner ring throttling channel 1551, and gas is also supplied from the outer ring outer chamber to the inner ring inner chamber through the second inner ring throttling channel 1561), while the outer ring flame remains extinguished. When the inner ring solenoid valve 162 is closed and the outer ring solenoid valve 161 is closed, the stopcock valve 110 rotates to a state with the outer ring flame closed and only the inner ring flame present (corresponding to state B). The flame control valve 150 makes the inner ring flame of the burner 120 become a low flame (at this time, gas is supplied from the inner ring outer chamber to the inner ring inner chamber only through the first inner ring throttling channel 1551), while the outer ring flame remains extinguished.

[0104] Mode 3: When the inner ring solenoid valve 162 is open and the outer ring solenoid valve 161 is closed, the stopcock valve 110 rotates to a position with both inner and outer ring flames (corresponding to state A). The flame control valve 150 keeps the inner ring flame of the burner 120 normal (the flame intensity is adjusted with the rotation of the stopcock valve 110), while the outer ring flame is extinguished. When the inner ring solenoid valve 162 is open and the outer ring solenoid valve 161 is closed, the stopcock valve 110 rotates to a position with the outer ring flame closed and only the inner ring flame present (corresponding to state B). The flame control valve 150 keeps the inner ring flame of the burner 120 normal (the flame intensity is adjusted with the rotation of the stopcock valve 110), while the outer ring flame is extinguished.

[0105] Mode 4: When the inner ring solenoid valve 162 is closed and the outer ring solenoid valve 161 is open, the stopcock valve 110 rotates to a position with both inner and outer ring flames (corresponding to state A). The flame control valve 150 keeps the inner ring flame of the burner 120 at a medium flame (at this time, gas is supplied from the outer inner ring chamber to the inner inner ring chamber through the first inner ring throttling channel 1551, and gas is also supplied from the outer outer ring chamber to the inner inner ring chamber through the second inner ring throttling channel 1561), while the outer ring flame remains normal (the flame intensity is adjusted with the rotation of the stopcock valve 110); when the inner ring solenoid valve 162 is closed and the outer ring solenoid valve 161 is open, When the stopcock valve 110 is rotated to the point where the outer ring flame is closed and only the inner ring flame is present (corresponding to state B), the flame control valve 150 keeps the inner ring flame of the burner 120 low (gas is supplied from the inner ring outer chamber to the inner ring inner chamber through the first inner ring throttling channel 1551), and the outer ring flame is also kept low (gas is supplied from the inner ring outer chamber to the inner ring inner chamber through the first inner ring throttling channel 1551, then from the inner ring inner chamber to the outer ring outer chamber through the second inner ring throttling channel 1561, and then supplied to the outer ring inner chamber through the open outer ring solenoid valve 161, thereby being supplied to the outer ring flame cap of the burner 120).

[0106] The A and B states of modes one through four are abbreviated as 1A, 2A, 3A, 4A and 1B, 2B, 3B, 4B, respectively.

[0107] 1A and 3B are the normal operating modes for users, which means that the flame control valve 150 is not used to control the flame of the stove 100 for a second time, and the operation of the stopcock valve 110 is relied upon only.

[0108] Modes 2A, 3A, and 4A can all be used for temperature control, as can modes 1B, 2B, and 4B. Low heat mode offers a better experience. Modes with low heat on the inner and outer rings, or low heat on the inner and outer rings with no heat, are all suitable for low-temperature cooking.

[0109] Since only 1A and 3B are the normal operating modes for users, when the flame control valve 150 is not needed to adjust the flame, the outer ring solenoid valve 161 needs to automatically close according to the rotation angle of the plug valve 110 to achieve the normal operating mode.

[0110] In this embodiment, a rotation detection unit is provided to detect whether the plug valve 110 has rotated to an angle where only the inner ring flame is present. When the plug valve 110 is not operated, both the inner ring solenoid valve 162 and the outer ring solenoid valve 161 are open. When the plug valve 110 rotates to the critical point of switching from inner and outer ring flames to only the inner ring flame, the outer ring solenoid valve 161 is closed, thereby automatically switching from mode A to mode B to enable normal user operation. When the plug valve 110 rotates in the opposite direction to the critical point of switching from only the inner ring flame to both inner and outer ring flames, the outer ring solenoid valve 161 is opened.

[0111] The rotation detection unit can be, for example, an angle sensor, or a positioning ring can be fitted onto the valve stem of the plug valve 110. Different positioning points are set on the positioning ring, and an optical sensor is used to detect the different positioning points to determine that the plug valve 110 has rotated to different angles.

[0112] Taking the maximum rotation angle of the plug valve 110 as 120°, 0-30° corresponds to only inner ring fire, 30°-95° ​​corresponds to both inner and outer ring fire, and 95°-120° corresponds to only inner ring fire as an example, when the rotation detection unit detects that the plug valve 110 rotates to 0-30° and 30°-95°, the control unit controls the outer ring solenoid valve 161 to close. When the rotation detection unit detects that the plug valve 110 rotates to 30°-95°, the control unit controls the outer ring solenoid valve 161 to open.

[0113] The operation of the flame control valve 150 (opening and closing of the internal and external solenoid valves) can be executed automatically through a pre-set program or manually through an externally set command switch. For example, buttons corresponding to different cooking scenarios can be set on the cooktop 100. When soup is needed, the corresponding button is triggered, causing the flame control valve 150 to perform the operation corresponding to that cooking scenario. It should be understood that the command switch corresponding to the cooking mode and the pre-set program have higher priority than the rotation detection unit. When a cooking mode is selected, the flame control valve 150 is no longer controlled by the rotation detection unit.
