Description

Technical Field

[0001] The present application relates to the technical field of stoves, and in particular to a gas stove. Background Art

[0002] A gas stove is one of the most commonly used kitchen cooking appliances in daily life. Gas enters the stove from the air inlet pipe, enters the burner after being regulated by the gas valve, and mixes with some air to form a mixed gas. The mixed gas is ejected from the fire hole of the ignition distributor and ignited by the igniter to form a flame, thereby heating the pot placed on the pot support.

[0003] In related technologies, in order to prevent the gas stove from dry-burning the cookware, an anti-dry-burn sensor is usually installed on the burner. The anti-dry-burn sensor can be used to detect the temperature of the pot above. When dry-burning occurs, the temperature of the bottom of the pot rises. The anti-dry-burn sensor can remind the user of the dry-burning situation according to the temperature change, and the igniter will close the solenoid valve in time to prevent accidents.

[0004] However, when the anti-dry-burn sensor is activated, the ingredients in the pot are already in a dry-burn state, and the moisture in the ingredients evaporates under high temperature, causing the cooked food to become dry, affecting the user's taste and cooking experience. Utility Model Content

[0005] The utility model aims to provide a gas stove, aiming to solve the problem of dry food during cooking on the gas stove.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a gas stove, which may include a stove housing, a burner, and an anti-dry burn assembly. The stove housing is formed with a mounting cavity; the burner is disposed in the mounting cavity and may include a combustion element, an air intake element, and a control valve. The combustion element is used to heat a pot mounted on the stove housing; the air intake element is connected to the combustion element and supplies gas to the combustion element; the control valve controls the connection between the combustion element and the air intake element; the anti-dry burn assembly is used to maintain the moisture content of food in the pot; the anti-dry burn assembly may include a first liquid level sensor and an igniter. The first liquid level sensor is used to detect the liquid level in the pot; a controller is electrically connected to the first liquid level sensor and the control valve and is used to control the control valve to close when the liquid level in the pot falls below a first preset level.

[0008] It can be understood that during the user's cooking process, as the burner continues to heat the pot, the moisture in the cooking ingredients (water, oil, cooking wine, etc.) and various ingredients (meat, vegetables or rice, etc.) added in the pot can precipitate and evaporate, causing the liquid level in the pot to drop. When it drops below the first liquid level sensor (i.e., the first preset height), the first liquid level sensor can synchronously generate a first electrical signal. After receiving the first electrical signal, the controller sends a closing instruction to the control valve, so that the control valve disconnects the gas supply in time, the burner no longer generates flames, and the temperature of the pot gradually drops, so that the soup no longer evaporates, effectively maintaining the moisture in the ingredients, thereby improving the taste of the meal and the user's cooking experience.

[0009] In some embodiments of the present application, the anti-dry burning assembly further includes a pulse igniter, and the controller forms at least a part of the pulse igniter.

[0014] In some embodiments of the present application, the clamping member may include a sliding portion and a clamping portion, the sliding portion is arranged in the slide groove and connected to the elastic member so that the sliding portion slides along the slide groove toward the supporting portion; the clamping portion is connected to the sliding portion, a clamping cavity is formed on the clamping portion, and the first liquid level sensor is arranged in the clamping cavity.

[0015] In some embodiments of the present application, the pot support may include a plurality of bases and a plurality of clamping members, wherein the plurality of bases are arranged at intervals around the combustion member, and each base is provided with a clamping member.

[0016] In some embodiments of the present application, the anti-dry burning component may further include a second liquid level sensor, which is used to detect the liquid level height in the pot. The controller is electrically connected to the second liquid level sensor and the control valve, and is used to control the control valve to close when the liquid level height in the pot is higher than a second preset height, wherein the second liquid level sensor is located at the top of the pot.

The combustion element is used to heat a pot mounted on the stove housing; the air intake element is used to supply gas to the combustion element; the control valve is used to control the connection between the combustion element and the air intake element; the dry-burn prevention assembly is used to maintain moisture in the pot, and the dry-burn prevention assembly includes a first liquid level sensor and a controller. The first liquid level sensor is used to detect the liquid level in the pot; the controller is used to control the valve to close when the liquid level in the pot falls below a first preset level.

[0018] It can be understood that during the user's cooking process, as the burner continues to heat the pot, the moisture in the cooking ingredients (water, oil, cooking wine, etc.) and various ingredients (meat, vegetables or rice, etc.) added in the pot can precipitate and evaporate, causing the liquid level in the pot to drop. When it drops below the first liquid level sensor (first preset height), the first liquid level sensor can synchronously generate a first electrical signal. After receiving the first electrical signal, the controller sends a closing instruction to the control valve, so that the control valve disconnects the gas supply in time, the burner no longer generates flames, and the temperature of the pot gradually drops, so that the soup no longer evaporates, effectively maintaining the moisture in the ingredients, thereby improving the taste of the meal and the user's cooking experience.

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0050] A gas stove is one of the most commonly used kitchen cooking appliances in daily life. Gas enters the stove from the air inlet pipe, enters the burner after being regulated by the gas valve, and mixes with some air to form a mixed gas. The mixed gas is ejected from the fire hole of the ignition distributor and ignited by the igniter to form a flame, thereby heating the pot placed on the pot support.

[0051] In related technologies, in order to prevent the gas stove from dry-burning the cookware, an anti-dry-burn sensor is usually installed on the burner. The anti-dry-burn sensor can be used to detect the temperature of the pot above. When dry-burning occurs, the temperature of the bottom of the pot rises. The anti-dry-burn sensor can remind the user of the dry-burning situation according to the temperature change, and the igniter will close the solenoid valve in time to prevent accidents.

[0052] However, when the anti-dry-burn sensor is activated, the ingredients in the pot are already in a dry-burn state, and the moisture in the ingredients evaporates under high temperature, causing the cooked food to become dry, affecting the user's taste and cooking experience.

[0053] Based on this, the present application provides a gas stove that can solve the problem of dry food during cooking on a gas stove and effectively improve the taste of food.

[0054] Figure 1 One of the structural diagrams of the gas stove provided in the embodiment of the present application is shown. Figure 2The second structural diagram of the gas stove provided in the embodiment of the present application is shown in conjunction with Figure 1 and Figure 2 In some embodiments of the present application, the gas stove 1 may include a stove housing 10 . The stove housing 10 may include a bottom shell 11 and a panel 12 . The panel 12 is connected to the bottom shell 11 and forms a mounting cavity 13 .

[0055] In this way, the installation cavity 13 can be used to install other components of the gas stove 1, and the panel 12 can provide a user with an operable platform to facilitate the user to perform cooking-related operations.

[0056] It should be noted that since the gas stove 1 generates a high-temperature open flame when in operation, to ensure the safe use of the gas stove 1, the panel 12 can be made of a high-temperature resistant and heat-insulating material, such as a microcrystalline panel or a NEG panel. This effectively isolates the high temperature above the panel 12, ensuring the safety of other components of the gas stove 1 installed in the installation cavity 13 and preventing the high temperature environment from adversely affecting their service life.

[0057] In some embodiments of this application, see Figure 1 and Figure 2 The gas stove 1 may further include a burner 20, which is disposed in the mounting cavity 13. As a core component of the gas stove 1, the burner 20 can mix gas and air in a certain manner and burn to generate flames, thereby heating and cooking the pots 2 (including frying pans, boiling pots, and casseroles) placed on the panel 12.

[0058] It should be noted that there can be only one burner 20 or two burners 20, which are spaced apart along the first direction F1. In this way, the user can cook on one burner 20 and stir-fry on the other burner 20, thereby speeding up cooking efficiency.

[0059] In some embodiments of this application, see Figure 2 The burner 20 may include a combustion element 21, and the combustion element 21 may include a burner head 211. An ejector tube 2111 and an air mixing chamber 2112 are formed inside the burner head 211. One end of the ejector tube 2111 is connected to the gas, and the other end of the ejector tube 2111 is connected to the air mixing chamber 2112. The air mixing chamber 2112 is also provided with an air inlet connected to the outside air.

[0060] In this way, the gas enters the mixing chamber 2112 through the ejector tube 2111 , and the air enters the mixing chamber 2112 through the air inlet, so that the gas and air can be mixed in the mixing chamber 2112 .

[0061] In some embodiments of this application, see Figure 2The burner 20 may further include a fire cover 212 , wherein a plurality of fire distribution ports are circumferentially spaced apart on the side wall surface of the fire cover 212 , and a plurality of gas outlets connected to the fire distribution holes 2121 are further provided on the gas mixing chamber 2112 .

[0062] In this way, the mixture formed by gas and air can flow out of the burner 211 from the air outlet and flow toward the multiple fire holes 2121. After the user ignites the mixture at the fire cover 212, each fire hole 2121 on the fire cover 212 can form a small flame, and multiple small flames surround the fire cover 212 to form a ring-shaped flame, thereby heating different positions of the bottom wall of the pot 2 above the burner 20, so that the pot 2 can be heated evenly.

[0063] Continue reading Figure 2 In some embodiments of the present application, the burner 20 may further include an air intake member 22, which may include a main pipe 221, a first branch pipe 222, and a second branch pipe 223. One end of the main pipe 221 is connected to the gas storage pipe, and the other end of the main pipe 221 is connected to the first branch pipe 222 and the second branch pipe 223 respectively. The other end of the first branch pipe 222 is connected to the ejector pipe 2111 of the left burner 20, and the other end of the second branch pipe 223 is connected to the ejector pipe 2111 of the right burner 20.

[0064] It should be noted that the fuel gas in the gas storage pipe may be liquefied gas, hydrogen, natural gas or other combustible gases.

[0065] In this way, the gas can first flow from the gas storage pipe into the main pipe 221, and then be diverted from the main pipe 221 to the first branch pipe 222 and the second branch pipe 223. The gas in the first branch pipe 222 enters the burner 211 on the left through the ejector pipe 2111 on the left, and the gas in the second branch pipe 223 enters the burner 211 on the right through the ejector pipe 2111 on the right, thereby supplying gas to the two burners 20 respectively.

[0066] Figure 3 The third structural diagram of the gas stove provided in the embodiment of the present application is shown in conjunction with Figure 2 and Figure 3 In some embodiments of the present application, the burner 20 may further include a control valve 23, which may be arranged on the main pipe 221, or on the first branch pipe 222 or the second branch pipe 223, so as to control the connection state between the combustion component 21 and the air intake component 22.

[0067] It should be noted that the control valve 23 may be an automatic control electrical component such as a solenoid valve or an electric valve.

[0068] Continue reading Figure 3In some embodiments of the present application, a first knob 224 is provided on the first branch pipe 222, and the first knob 224 can control the opening size of the valve core located in the first branch pipe 222. A second knob 225 is provided on the second branch pipe 223, and the second knob 225 can be used to control the opening size of the valve core located in the second branch pipe 223.

[0069] In this way, the user can control the flow rate of the gas in the first branch pipe 222 and the second branch pipe 223 through the first knob 224 and the second knob 225 respectively, and then control the fire size of the two burners 211 respectively.

[0070] The above briefly introduces the overall structure of the gas stove of the present application. Generally, the gas stove can also include an anti-dry burning sensor, which can detect the temperature of the pot above. When dry burning occurs, the anti-dry burning sensor can remind the user of the dry burning situation based on the detected temperature and close the solenoid valve in time to prevent accidents.

[0071] However, the anti-dry-burn sensor used in related technologies uses a temperature sensor. After the water in the pot has been completely evaporated by the gas stove, the gas stove needs to continue heating the pot until the temperature reaches the alarm temperature of the temperature sensor before triggering the solenoid valve to cut off the gas supply. However, by this time, the ingredients in the pot have already been dried out. The moisture in the ingredients evaporates under the high temperature, resulting in a dry-cooked meal. For beginners, it is difficult to control the fire power of the gas stove and the cooking time, which makes the food more likely to dry out.

[0072] This application uses a liquid level sensor as an anti-dry burn sensor, which can promptly disconnect the gas supply when the liquid level in the pot is low, effectively maintaining the moisture of various ingredients in the pot, thereby improving the taste of the food and the user's cooking experience. The following will be combined with the accompanying drawings to describe in detail the structure and working principle of the anti-dry burn component in the gas stove provided by this application.

[0073] Figure 4 The fourth structural diagram of the gas stove provided in the embodiment of the present application is shown. Figure 4 In some embodiments of the present application, the gas stove 1 may further include an anti-dry burning component 30. The anti-dry burning component 30 may include a first liquid level sensor 31. The first liquid level sensor 31 generates a first electrical signal in response to changes in the height of the liquid level in the pot 2.

[0074] It should be noted that the first liquid level sensor 31 here can be a non-contact liquid level sensor or a contact liquid level sensor. When a non-contact liquid level sensor is used, it can be placed outside the pot 2 to avoid contamination or damage that may be caused by the contact liquid level sensor. In addition, the non-contact liquid level sensor responds faster to changes in liquid level height, thereby ensuring the timeliness of the detection data.

[0075] It should also be noted that the non-contact liquid level sensor can be a resistive liquid level sensor, a capacitive liquid level sensor or an acoustic liquid level sensor, as long as it can generate a first electrical signal in response to changes in the liquid level in the pot 2. The first electrical signal can be a resistance value or a capacitance value, etc.

[0076] See also Figure 3 and Figure 4 In some embodiments of the present application, the anti-dry burn assembly 30 may further include an igniter 32. The igniter 32 may be a pulse igniter that ignites the gas by generating intermittent pulse current, thereby forming a flame. The igniter 32 includes a controller. The input end of the controller in the igniter 32 is electrically connected to the first liquid level sensor 31, and the output end of the controller is electrically connected to the control valve 23. When the input end receives a first electrical signal, the output end sends a closing signal to the control valve 23.

[0077] It can be understood that during the user's cooking process, as the burner 20 continues to heat the pot 2, the moisture in the cooking ingredients (water, oil, cooking wine, etc.) and various ingredients (meat, vegetables or rice, etc.) added in the pot 2 can precipitate and evaporate, causing the liquid level in the pot 2 to drop. When it drops below the first liquid level sensor 31, the first liquid level sensor 31 can synchronously generate a first electrical signal. After receiving the first electrical signal, the igniter 32 sends a closing instruction to the control valve 23, so that the control valve 23 disconnects the gas supply of the main pipeline 221 in time, the burner 20 no longer generates flames, and the temperature of the pot 2 gradually drops, so that the soup no longer evaporates, effectively maintaining the moisture in the ingredients, thereby improving the taste of the meal and the user's cooking experience.

[0078] Continue reading Figure 4 In some embodiments of the present application, the anti-dry burning assembly 30 may further include a pot support 40 , one end of the pot support 40 is connected to the stove housing 10 , and the other end of the pot support 40 is connected to the pot 2 .

[0079] In this way, since the outer flame temperature is higher than the inner flame temperature, the pot support 40 can separate the pot 2 from the burner 20, so that the outer flame of the flame generated by the burner 20 heats the bottom wall of the pot 2, thereby improving cooking efficiency.

[0080] Continue reading Figure 4In some embodiments of the present application, the first liquid level sensor 31 is arranged at one end of the pot support 40 facing the pot 2, and the first liquid level sensor 31 is spaced apart from the bottom of the pot 2.

[0081] It can be understood that the first liquid level sensor 31 is spaced apart from the bottom of the pot 2 so that before the liquid level in the pot 2 approaches the bottom of the pot 2, the first liquid level sensor 31 can generate a first electrical signal to control the burner 20 to extinguish in advance, thereby preventing the residual heat in the pot 2 from continuing to bake the moisture in the food, causing the food to become dry.

[0082] In addition, the present application can also control the liquid level in the pot 2 by adjusting the length of the first distance L1 between the first liquid level sensor 31 and the bottom of the pot 2, so that the user can perform diversified operations according to specific cooking needs.

[0083] For example, if the user wants the porridge to be thicker, the first liquid level sensor 31 can be installed at a lower position of the pot support 40 so that the first distance L1 is smaller. In this way, the amount of water is smaller when the amount of rice is constant, and the porridge is thicker after cooking. Conversely, if the user wants the porridge to be thinner, the first liquid level sensor 31 can be installed at an upper position of the pot support 40 so that the first distance L1 is larger. In this way, the amount of water is larger when the amount of rice is constant, and the porridge is thinner after cooking.

[0084] For example, if the dish cooked by the user requires a higher water content, such as scrambled eggs with tomatoes, the first liquid level sensor 31 can be installed at the upper position of the pot support 40, so that more soup is retained in the pot 2, and the dish has a soft and rich taste after cooking; conversely, if the dish cooked by the user requires a lower water content, such as dry-pot cauliflower, the first liquid level sensor 31 can be installed at the lower position of the pot support 40, so that less soup is retained in the pot 2, and the dish has a crisp and refreshing taste after cooking.

[0085] Figure 5 The fifth structural diagram of the gas stove provided in the embodiment of the present application is shown in conjunction with Figure 4 and Figure 5 In some embodiments of the present application, the pot support 40 may include a base 41 , one side of the base 41 is connected to the cooker housing 10 , and the other side of the base 41 abuts against the bottom wall of the pot 2 .

[0086] Continue reading Figure 4 and Figure 5 In some embodiments of the present application, the pot support 40 may further include a clamping member 42, which is arranged on the base 41 and can move toward the side wall of the pot 2, wherein the first liquid level sensor 31 is arranged on the side of the clamping member 42 facing the pot 2.

[0087] In this way, on the one hand, the bottom wall of the pot 2 can be stably supported by the base 41, and the side walls of the pot 2 can be stably clamped by the clamping member 42, so that the pot 2 can be stably placed on the pot support 40. On the other hand, since the clamping member 42 can move relative to the base 41 toward the side wall of the pot 2, when pots 2 of different diameters are placed on the pot support 40, the distance between the clamping member 42 and the side wall of the pot 2 can be adjusted so that the first liquid level sensor 31 arranged on the clamping member 42 can always be in contact with the side wall of the pot 2, thereby effectively measuring the liquid level in the pot 2.

[0088] Continue reading Figure 4 and Figure 5 In some embodiments of the present application, the pot support 40 may include a plurality of bases 41 and a plurality of clamping members 42 , wherein the plurality of bases 41 are arranged circumferentially around the combustion member 21 at intervals, and each base 41 is provided with a clamping member 42 .

[0089] For example, the pot support 40 may include two bases 41 and two clamping members 42. The two bases 41 are respectively disposed on opposite sides of the pot 2 along the first direction F1. A clamping member 42 is correspondingly disposed on each base 41, and each clamping member 42 can move relative to its respective base 41 along the first direction F1 toward the pot 2. In this way, the two clamping members 42 can stably clamp on both sides of the pot 2, allowing the first liquid level sensor 31 on the clamping member 42 to closely fit the side wall of the pot 2.

[0090] For example, the pot support 40 may also include three bases 41 and three clamping members 42, and the angle between each clamping member 42 is 60°, or the pot support 40 may also include four bases 41 and four clamping members 42, and the angle between each clamping member 42 is 90°, both of which can enable the clamping members 42 to stably clamp the pot 2, and the first liquid level sensor 31 is tightly fitted with the side wall of the pot 2.

[0091] It should be noted that the first liquid level sensor 31 may be installed on only one clamping member 42, while the other clamping members 42 may not be installed with the first liquid level sensor 31 and only be used to abut the cookware 2. Alternatively, a first liquid level sensor 31 may be installed on each clamping member 42. In this way, if one first liquid level sensor 31 is damaged, the other first liquid level sensors 31 can continue to detect, ensuring the normal function of the dry-boiling prevention function, and reducing the system error of the first liquid level sensors 31.

[0092] There are many ways to realize the movement of the clamping member 42 toward the cookware 2 . Various possible structures of the cookware support 40 are described below.

[0093] Figure 6The sixth structural diagram of the gas stove provided in the embodiment of the present application is shown. Figure 6 In some embodiments of the present application, two of the clamping members 42 of the pot support 40 can slide on the base 41 along the first direction F1 toward the pot 2, and the other two clamping members 42 can slide along the second direction F2 toward the pot 2. The user can stably place pots 2 of different sizes into the pot support 40 by sliding the two clamping members 42 in the first direction F1 and the two clamping members 42 in the second direction F2.

[0094] Figure 7 The seventh structural diagram of the gas stove provided in the embodiment of the present application is shown. Figure 7 In order to achieve the sliding of the clamping member 42 on the base 41, in some embodiments of the present application, the pot support 40 may further include an elastic member 43. The elastic member 43 may be a spring, an elastic rubber strip or a rubber band, etc. The following description will be made using a spring as an example.

[0095] See also Figure 4 and Figure 7 The base 41 may include a base portion 411, one side of which is connected to the cooktop housing 10, and a chute 4110 defined on the other side of the base portion 411. The clamping member 42 is disposed within the chute 4110. The base portion 411 may be a polygonal prism, a trapezoidal platform, or a cylindrical platform, as long as it provides stable load-bearing properties and prevents the cookware 2 from shaking after being placed therein. The chute 4110 defined on the base portion 411 may also be a polygonal prism, a trapezoidal platform, or a cylindrical platform, as long as it can cooperate with the clamping member 42. This is not limited herein.

[0096] Continue reading Figure 7 In some embodiments of the present application, the base 41 may further include a supporting portion 412, which is arranged on the base portion 411. The supporting portion 412 may be a flat plate structure, which is arranged in the slide groove 4110 and extends toward the cookware 2. The two side walls of the flat plate are respectively engaged with the side walls of the slide groove 4110, so that the flat plate is stably connected to the base portion 411, and the top wall of the flat plate can abut against the bottom wall of the cookware 2, thereby being used to support the cookware 2.

[0097] In addition, the support portion 412 can also provide a connection fulcrum for the first spring 431. One end of the first spring 431 is connected to the support portion 412, and the other end of the first spring 431 is connected to the clamping member 42, so that the clamping member 42 slides toward the support portion 412 under the elastic force of the first spring 431.

[0098] It can be understood that when the pot 2 is not placed in the pot support 40, under the pulling force of the first spring 431, the diameter of the clamping cavity 423 enclosed by the four clamping members 42 is relatively small. For the pot 2 with a larger diameter, it cannot be placed directly on the pot support 40. At this time, the user can pull any two adjacent clamping members 42 toward the outside along the slide groove 4110 so that the diameter of the clamping cavity 423 enclosed by the clamping members 42 is larger than the diameter of the pot 2, and the pot 2 can be placed on the supporting portion 412 of the pot support 40. Finally, the clamping member 42 is released, so that the clamping member 42 slides toward the pot 2 along the slide groove 4110 under the elastic force of the first spring 431 until the first liquid level sensor 31 installed on the clamping member 42 abuts against the side wall of the pot 2.

[0099] Figure 8 Shown Figure 7 A schematic diagram of the enlarged structure at position A. Figure 9 The eighth structural diagram of the gas stove provided in the embodiment of the present application is shown in conjunction with Figure 7 、 Figure 8 and Figure 9 In some embodiments of the present application, the clamping member 42 may include a sliding portion 421, which is disposed in the slide groove 4110 and connected to the first spring 431. The specific structure of the sliding portion 421 may be a polygonal prism, a trapezoidal table or a cylindrical table, as long as it can cooperate with the slide groove 4110.

[0100] Continue reading Figure 8 In some embodiments of the present application, a connecting plate 4210 extends upward from the right end of the sliding portion 421, and the first spring 431 is horizontally connected to the connecting plate 4210. In this way, the first spring 431 can be in a horizontal state, and the direction of the elastic force is also horizontal. Under the action of the horizontal elastic force, the sliding portion 421 can slide more stably and smoothly.

[0101] Continue reading Figure 8 and Figure 9 In some embodiments of the present application, the clamping member 42 may further include a clamping portion 422 connected to the sliding portion 421. The clamping portion 422 may have a clamping cavity 423 formed therein, and the first liquid level sensor 31 may be disposed within the clamping cavity 423. In this manner, the clamping portion 422 may slide along with the sliding portion 421, thereby causing the first liquid level sensor 31 to abut against the side wall of the cookware 2.

[0102] It should be noted that the clamping portion 422 can be formed by stamping and bending a flat plate. Specifically, a first mounting plate 4221 can be stamped out from the middle of the flat plate, and then bent from the left side and top of the flat plate to form a second mounting plate 4222 and a third mounting plate 4223.

[0103] In this way, the first mounting plate 4221, the second mounting plate 4222 and the third mounting plate 4223 can enclose a clamping cavity 423, and the first liquid level sensor 31 can be pushed into the clamping cavity 423 from the placement port 424 at the right end of the clamping portion 422, so that the first liquid level sensor 31 can be stably placed in the clamping cavity 423.

[0104] Figure 10 The ninth structural diagram of the gas stove provided in the embodiment of the present application is shown. Figure 10 In some embodiments of the present application, the anti-dry burning component 30 may also include a second liquid level sensor 33. Similar to the first liquid level sensor 31, the second liquid level sensor 33 may also use a resistive liquid level sensor, a capacitive liquid level sensor or an acoustic liquid level sensor, as long as it can generate a second electrical signal in response to changes in the liquid level in the pot 2. The second electrical signal may be a resistance value or a capacitance value, etc.

[0105] See also Figure 3 and Figure 10 The input end of the igniter 32 is electrically connected to the second liquid level sensor 33. When the input end receives the second electrical signal, the output end sends a closing signal to the control valve 23. The second liquid level sensor 33 is located at the top of the pot 2. It is understandable that when the liquid level in the pot 2 is high, if the pot 2 continues to be heated, the boiling of the liquid in the pot 2 will intensify, and there may be a risk of overflowing the pot 2, causing contamination of the gas stove 1 and the kitchen counter.

[0106] Therefore, the present application can set a second liquid level sensor 33 on the top of the pot 2. In this way, when the liquid level in the pot 2 is greater than the second liquid level sensor 33, the second liquid level sensor 33 can synchronously generate a second electrical signal. After receiving the second electrical signal, the igniter 32 sends a closing instruction to the control valve 23, so that the control valve 23 disconnects the gas supply of the main pipeline 221 in time, the burner 20 no longer generates flames, and the temperature of the pot 2 gradually drops, so that the liquid in the pot 2 no longer boils, thereby avoiding the situation where the liquid overflows from the pot 2.

[0107] Continue reading Figure 10 There is a second distance L2 between the second liquid level sensor 33 and the top of the pot 2. It can be understood that the second liquid level sensor 32 is spaced apart from the top of the pot 2 so that the second liquid level sensor 32 can generate a second electrical signal before the liquid level in the pot 2 approaches the top of the pot 2, thereby controlling the burner 20 to shut down in advance, thereby preventing the residual heat of the pot 2 from continuing to heat the liquid and causing the liquid to overflow from the pot surface.

[0108] It should be noted that the specific length of the second spacing L2 can be set according to the fire power of the gas stove 1. When the fire power of the gas stove 1 is high, the boiling degree of the liquid in the pot 2 is relatively intense. Therefore, a longer distance can be reserved for the second spacing L2; conversely, when the fire power of the gas stove 1 is low, the boiling degree of the liquid in the pot 2 is relatively low. Therefore, a shorter distance can be reserved for the second spacing L2.

[0109] Figure 11 The tenth structural diagram of the gas stove provided in the embodiment of the present application is shown. Figure 12 Shown Figure 11 The enlarged structural diagram at position B is shown in conjunction with Figure 10 、 Figure 11 and Figure 12 In some embodiments of the present application, a second spring 432 is provided at the end of the slide 4110 facing away from the cookware 2. One end of the second spring 432 is connected to the base 411, and the other end of the second spring 432 can abut against the sliding portion 421. In this way, springs are provided on both the left and right sides of the sliding portion 421. The left side of the sliding portion 421 abuts against the first spring 431, and the right side of the sliding portion 421 abuts against the second spring 432.

[0110] As can be understood, when the sliding portion 421 moves too far to the right, the second spring 432 on the right side will exert a leftward resistance force on the sliding portion 421, preventing the sliding portion 421 from continuing to slide to the right and causing the first spring 431 on the left side to overload and fail or break. In addition, the two springs holding the sliding portion 421 can make the sliding portion 421 slide more smoothly within the sliding groove 4110.

[0111] Figure 13 The structural diagram of the gas stove provided in the embodiment of the present application is shown in FIG11. Figure 10 and Figure 13 In some embodiments of the present application, the movement of the clamping member 42 toward the cookware 2 can also be driven by other driving members. For example, a cylinder 43 is also provided on the panel 12 or the base 41, and the output shaft of the cylinder 43 reciprocates along the first direction, driving the clamping member 42 to slide along the slide groove 4110, so that the first liquid level sensor 31 is tightly attached to the side wall of the cookware 2, so that the first liquid level sensor 31 can effectively detect the liquid level height in the cookware 2.

[0112] In some other embodiments, the movement of the clamping member 42 toward the cookware 2 can also be in the form of a screw. Specifically, the slide groove 4110 is provided with a ball screw, and a nut platform is provided on the ball screw. The clamping member 42 is arranged on the nut platform. The ball screw can be driven by a motor. In this way, when the motor rotates, it can drive the ball screw to rotate, and the nut platform can move relative to the ball screw along the first direction F1, thereby also realizing the movement of the clamping member 42 toward the cookware 2.

[0113] Figure 14 The structural diagram of the gas stove provided in the embodiment of the present application is shown in FIG. Figure 11 and Figure 14 In some embodiments of the present application, the pot support 40 may further include a connecting support 44 , which is disposed on the panel 12 , with a plurality of bases 41 evenly arranged on the connecting support 44 , and the burner 20 installed in a cavity in the middle of the connecting support 44 .

[0114] In this way, when the gas stove 1 needs to be disassembled for maintenance, it is only necessary to remove the connecting bracket 44 from the panel 12 to separate the plurality of bases 41 and the clamping members 42 on the bases 41 from the panel 12 .
