Description

Technical Field

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

[0002] The fully premixed gas stove adopts the principle of full premixing combustion, that is, before the gas burns, it has been mixed with a sufficient amount of air (the primary air coefficient reaches 1.0 - 1.06, and the ratio of the amount of air pre-mixed with the gas in the burner to the theoretical air is called the primary air coefficient), so that the gas burns more fully when burning. The flame formed by the combustion of the fully premixed gas has a high temperature, a short flame, and good flame temperature uniformity. Therefore, it is the future development direction of gas stoves, and can play a significant role in the field of intelligent control cooking.

[0003] However, when the traditional fully premixed gas stove is in use, the temperature of the burner is too high, there is a backfire phenomenon, which reduces the service life of the burner. Summary of the Invention

[0004] Based on this, aiming at the problems that when the traditional fully premixed gas stove is in use, the temperature of the burner is too high, there is a backfire phenomenon, and the service life of the burner is reduced, a gas stove is proposed. When the gas stove is in use, it can cool the burner, thereby avoiding the generation of backfire problems, and thus improving the service life of the burner.

[0005] The specific technical solutions are as follows:

[0006] The present application relates to a gas stove, including a burner and a pressure stabilizing component. The burner includes a burner body and an ejector tube. The air inlet of the burner body is communicated with the outlet end of the ejector tube. The pressure stabilizing component includes a pressure stabilizing member and a pressure stabilizing chamber. The pressure stabilizing chamber is provided with a pressure stabilizing cavity for accommodating air and gas. The pressure stabilizing chamber is also provided with a pressure stabilizing channel and an installation through hole communicated with the pressure stabilizing cavity. The inlet end of the ejector tube passes through the installation through hole and is arranged in the pressure stabilizing cavity. Air and gas enter the ejector tube along the inlet end of the ejector tube respectively and are mixed. The pressure stabilizing member is arranged in the pressure stabilizing channel to open or close the pressure stabilizing channel. The burner body is arranged on the flow path of the gas discharged along the pressure stabilizing channel to cool the burner body through the gas discharged along the pressure stabilizing channel.

[0007] The technical solutions are further described below:

[0008] In one embodiment, part or all of the structure of the burner body faces the air outlet of the pressure stabilizing channel.

[0009] In one of the embodiments, a connecting pipe is further included, one end of which is connected to the air outlet of the pressure stabilizing channel, and the other end of which is directed toward the burner body.

[0010] In one of the embodiments, the number of the pressure-stabilizing channels and the number of the pressure-stabilizing parts are at least two, and the pressure-stabilizing channels correspond to the pressure-stabilizing parts one by one, and the air outlet of at least one of the pressure-stabilizing channels faces the burner body.

[0011] In one of the embodiments, the pressure stabilizing component is disposed in the pressure stabilizing channel, and the pressure stabilizing component adjusts the air flow of the pressure stabilizing channel according to the air pressure in the pressure stabilizing chamber to adjust the air pressure in the pressure stabilizing chamber.

[0012] In one of the embodiments, the pressure stabilizing member is movably inserted into the pressure stabilizing channel, and the pressure stabilizing member moves relative to the pressure stabilizing channel to adjust the volume of the air outlet gap formed between the pressure stabilizing member and the inner wall of the pressure stabilizing channel.

[0013] In one embodiment, the voltage stabilizing member includes a switch segment, a connecting segment and a trigger segment connected in sequence, the connecting segment is movably inserted in the voltage stabilizing channel, the trigger segment is arranged in the voltage stabilizing cavity, and the switch segment is arranged outside the voltage stabilizing cavity;

[0014] The pressure stabilizing component seals the pressure stabilizing channel through the switch section and the connecting section is driven by the trigger section to move the switch section to adjust the volume of the air outlet gap formed between the switch section and the inner wall of the pressure stabilizing channel.

[0015] In one of the embodiments, the pressure stabilizing member further includes an elastic body, which is sleeved on the connecting section, one end of the elastic body abuts against the inner wall of the pressure stabilizing chamber, and the other end of the elastic body abuts against the triggering section.

[0016] In one embodiment, the elastic body has a first state, a second state and a third state;

[0017] When the elastic body is in the first state, the elastic body is under pressure, and the elastic body applies a thrust to the trigger segment to make the switch segment and the pressure-stabilizing channel seal and cooperate;

[0018] When the elastic body is in the second state, the elastic body is under pressure, the triggering section is forced to squeeze the elastic body and drive the connecting section to drive the switch section to open the voltage stabilizing channel;

[0019] When the elastomer is in the third state, the elastomer is compressed, and under the action of the restoring force, the elastomer pushes the trigger section to drive the connection section to move, so that the switch section moves along the direction close to the voltage stabilizing channel.

[0020] In one embodiment, the voltage stabilizing channel includes an adjusting section, and the cross-sectional area of the adjusting section gradually increases along the exhaust direction of the adjusting section. The switch section cooperates with the inner wall of the adjusting section in contact to block the voltage stabilizing channel;

[0021] When the switch section moves relative to the adjusting section along the air outlet direction of the adjusting section, the volume of the air outlet gap formed between the switch section and the inner wall of the voltage stabilizing channel gradually increases;

[0022] When the switch section moves relative to the adjusting section along the reverse direction opposite to the air outlet direction of the adjusting section, the volume of the air outlet gap formed between the switch section and the inner wall of the voltage stabilizing channel gradually decreases.

[0023] In one embodiment, the shape of the switch section matches the shape of the adjusting section.

[0024] In one embodiment, the gas stove further includes a gas joint and an air joint. The voltage stabilizing chamber is further provided with a first air inlet hole and a second air inlet hole communicating with the voltage stabilizing cavity. The air joint is arranged at the first air inlet hole to supply air to the voltage stabilizing cavity through the air joint. The ejector pipe is provided with a third air inlet hole and a fourth air inlet hole. The gas joint passes through the second air inlet hole and communicates with the fourth air inlet hole to supply gas to the ejector pipe. The third air inlet hole allows the air in the voltage stabilizing cavity to enter.

[0025] When the above gas stove is in use, air and gas respectively enter the ejector pipe from the air inlet end of the ejector pipe for mixing, and then are supplied to the burner body for combustion. The voltage stabilizing cavity is filled with air. When the voltage stabilizing member opens the voltage stabilizing cavity, the air in the voltage stabilizing cavity is discharged along the voltage stabilizing channel. Since the burner body is arranged on the flow path of the gas discharged along the voltage stabilizing channel, the gas discharged along the voltage stabilizing channel can cool the burner body, thereby avoiding the occurrence of flashback phenomenon of the burner body, and thus improving the service life of the burner.

[0042] The present application proposes a gas stove 10, which can cool the burner 200 during use, thereby avoiding the occurrence of flashback problems and improving the service life of the burner 200.

[0043] Please refer to Figure 1 and Figure 2 , in one embodiment, the gas stove 10 includes a burner 200 and a voltage stabilizing component 100. The burner 200 includes a burner body 210 and an ejector tube 220. The air inlet of the burner body 210 is communicated with the outlet end of the ejector tube 220. The voltage stabilizing component 100 includes a voltage stabilizing chamber 110. The voltage stabilizing chamber 110 is provided with a voltage stabilizing cavity 112 for accommodating air and gas. The voltage stabilizing chamber 110 is further provided with a voltage stabilizing channel 1124 communicated with the voltage stabilizing cavity 112 and an installation through hole (not shown). The inlet end of the ejector tube 220 passes through the installation through hole and is arranged in the voltage stabilizing cavity 112, and air and gas enter the ejector tube 220 through the inlet end of the ejector tube 220 respectively and are mixed.

[0044] Please refer to Figure 1 and Figure 2, the pressure stabilizing chamber 110 is also provided with a first air inlet hole and a second air inlet hole 1122. The gas stove 10 further includes a gas connector 400 and an air connector 300. The air connector 300 is inserted into the first air inlet hole (not shown), and air enters the pressure stabilizing chamber 110 through the air connector 300. The ejector pipe 220 is provided with a third air inlet hole 222 and a fourth air inlet hole 224. The gas connector 400 passes through the second air inlet hole 1122 and communicates with the fourth air inlet hole 224. Gas enters the fourth air inlet hole 224 through the gas connector 400 and enters the ejector pipe 220 through the fourth air inlet hole 224. The air entering the pressure stabilizing chamber 110 along the air connector 300 enters the ejector pipe 220 through the third air inlet hole 222 and is mixed with the gas in the ejector pipe 220.

[0045] Please refer to Figure 2 , in one specific embodiment, in order to avoid the air disturbing the gas, the conveying direction of the air connector 300 (refer to Figure 2 , the L1 direction) and the conveying direction of the gas connector 400 (refer to Figure 2 , the L2 direction) are perpendicular or nearly perpendicular. In this way, when the air enters the pressure stabilizing chamber 110 through the air connector 300, it will not directly blow towards the gas, resulting in less interference to the gas. Further, the conveying direction of the gas connector 400 should be consistent with the transmission direction of the ejector pipe 220 to avoid interfering with the gas transmission.

[0046] Among them, the conveying direction of the air connector 300 being nearly perpendicular to the conveying direction of the gas connector 400 means that the included angle between the conveying direction of the air connector 300 and the conveying direction of the gas connector 400 is between 85° and 95°.

[0047] Please refer to Figures 1 to 3 , in one embodiment, the pressure stabilizing component 100 further includes a pressure stabilizing member 120. The pressure stabilizing chamber 110 is also provided with a pressure stabilizing channel 1124 communicating with the pressure stabilizing cavity 112. The pressure stabilizing member 120 is arranged in the pressure stabilizing channel 1124, and the pressure stabilizing member 120 is used to open or close the pressure stabilizing channel 1124. For example, when the air pressure in the pressure stabilizing cavity 112 reaches a preset value, the pressure stabilizing member 120 opens the pressure stabilizing channel 1124; when the gas stove 10 is not working or the air pressure in the pressure stabilizing cavity 112 is small, the pressure stabilizing member 120 closes the pressure stabilizing channel 1124.

[0048] Since in the traditional gas stove 10 during use, the temperature of the burner body 210 is relatively high, the gas will be ignited in the pipeline inside the burner body 210, resulting in a flashback phenomenon and reducing the service life of the burner 200.

[0049] Based on the above problems, please refer to Figures 1 to 3 , in one embodiment, the burner body 210 is arranged on the flow path of the gas discharged along the pressure stabilizing channel 1124.

[0050] The cooling principle of the gas stove 10 is: air and gas enter the ejector tube 220 along the air inlet end of the ejector tube 220, mix, and then are provided to the burner body 210 for combustion. The pressure stabilizing chamber 112 is equipped with air. When the pressure stabilizing member 120 opens the pressure stabilizing chamber 112, the air in the pressure stabilizing chamber 112 is discharged along the pressure stabilizing channel 1124. Since the burner body 210 is arranged on the flow path of the gas discharged along the pressure stabilizing channel 1124, the gas discharged along the pressure stabilizing channel 1124 can cool the burner body 210, thereby avoiding the flashback phenomenon of the burner body 210, thereby improving the service life of the burner 200.

[0051] Among them, the flow path of the burner body 210 in the flow path of the gas discharged along the pressure-stabilizing channel 1124 can be a straight path or a curved path, as long as the gas discharged along the pressure-stabilizing channel 1124 can cool down the burner body 210 on the transmission path.

[0052] Please refer to Figure 1 and Figure 2 Specifically, in one embodiment, part or all of the structure in the burner body 210 faces the air outlet of the pressure stabilizing channel 1124. In this way, when the gas is discharged along the pressure stabilizing channel 1124, it can be directly blown toward the burner body 210, thereby improving the reliability of cooling.

[0053] In another embodiment, the gas stove 10 further includes a guide pipe (not shown), one end of which is connected to the air outlet of the pressure stabilizing channel 1124, and the other end of which is directed toward the burner body 210. In this way, the gas discharged from the air outlet of the pressure stabilizing channel 1124 is guided by the guide pipe to blow the gas toward the burner body 210, thereby improving the reliability of cooling.

[0054] Please refer to Figure 1 Specifically, in one embodiment, the number of the pressure stabilizing channels 1124 and the pressure stabilizing member 120 is at least two, and the pressure stabilizing channels 1124 correspond to the pressure stabilizing members 120 one by one, and the air outlet of at least one pressure stabilizing channel 1124 faces the burner body 210. In this way, it is ensured that the gas discharged from the air outlet of at least one pressure stabilizing channel 1124 is blown toward the burner body 210, and the burner body 210 is cooled, thereby ensuring the reliability of the cooling.

[0055] Please refer to Figure 1, in this embodiment, the number of the voltage stabilizing channels 1124 and the voltage stabilizing members 120 is two, and the voltage stabilizing channels 1124 and the voltage stabilizing members 120 are in one-to-one correspondence, and the air outlet of one of the voltage stabilizing channels 1124 faces the burner body 210. In other embodiments, the number of the voltage stabilizing channels 1124 and the voltage stabilizing members 120 can also be three or more, and the voltage stabilizing channels 1124 and the voltage stabilizing members 120 are in one-to-one correspondence, as long as it is ensured that the air outlet of at least one voltage stabilizing channel 1124 faces the burner body 210, which will not be elaborated one by one here.

[0056] In order to make the primary air coefficient of the gas stove 10 (the ratio of the amount of air pre-mixed with gas in the burner 200 to the theoretical air is called the primary air coefficient) fluctuate less, it is necessary to control the air pressure in the voltage stabilizing chamber 110 so that the amount of air entering the ejector tube 220 along the third air inlet hole 222 fluctuates less under the action of the air pressure.

[0057] For the above purpose, please refer to Figure 1 , Figure 3 and Figure 4 , in one embodiment, the voltage stabilizing member 120 can adjust the air output of the voltage stabilizing channel 1124 according to the pressure in the voltage stabilizing chamber 112 to adjust the air pressure in the voltage stabilizing chamber 112.

[0058] The working principle of the above gas stove 10 is as follows: The gas enters the ejector tube 220 of the burner 200 through the second air inlet hole 1122, and the air enters the voltage stabilizing chamber 110 along the first air inlet hole. As the air pressure in the voltage stabilizing chamber 110 increases, under the action of the air pressure, it enters the ejector tube 220 to be mixed with the gas. As the air is continuously input, the air pressure in the voltage stabilizing chamber 110 gradually increases. At this time, the voltage stabilizing member 120 opens the voltage stabilizing channel 1124, and the gas in the voltage stabilizing chamber 112 can be discharged through the voltage stabilizing channel 1124. The voltage stabilizing member 120 can adjust the air output along the voltage stabilizing channel 1124 according to the air pressure in the voltage stabilizing chamber 112, and then adjust the air pressure in the voltage stabilizing chamber 112; for example, when the air pressure in the voltage stabilizing chamber 112 is too high, the voltage stabilizing member 120 drives the voltage stabilizing channel 1124 to increase the air output to achieve the purpose of pressure relief; when the air pressure in the voltage stabilizing chamber 112 is too low, the voltage stabilizing member 120 drives the voltage stabilizing channel 1124 to reduce the air output to achieve the purpose of pressure increase. At this time, the voltage stabilizing member 120 can adjust the air pressure in the voltage stabilizing chamber 112 according to the pressure in the voltage stabilizing chamber 112, so that the air pressure in the voltage stabilizing chamber 110 is maintained at a preset value, and then the amount of air entering the ejector tube 220 under the action of the air pressure fluctuates less, and then the primary air mixing coefficient fluctuates less. In this way, the performance of the gas stove 10 can be more stable during use.

[0059] Next, the structure of the voltage stabilizing member 120 and the principle of the voltage stabilizing member 120 adjusting the air pressure in the voltage stabilizing chamber 112 will be specifically described in combination with the embodiments.

[0060] Please refer to Figure 1 、 Figure 5 and Figure 6 In one specific embodiment, the voltage stabilizing member 120 is movably inserted into the voltage stabilizing channel 1124 to open or close the voltage stabilizing channel 1124. The voltage stabilizing member 120 moves relative to the voltage stabilizing channel 1124 to adjust the volume of the air outlet gap 130 formed between the voltage stabilizing member 120 and the inner wall of the voltage stabilizing channel 1124.

[0061] Among them, please refer to Figure 6 The air outlet gap 130 refers to: when the voltage stabilizing member 120 moves relative to the voltage stabilizing channel 1124, an air outlet gap 130 will be formed between the voltage stabilizing member 120 and the inner wall of the voltage stabilizing channel 1124. The gas in the voltage stabilizing cavity 112 is discharged along the air outlet gap 130. Adjusting the volume of the air outlet gap 130 can adjust the air outlet volume, and further adjust the air pressure in the voltage stabilizing cavity 112.

[0062] Please refer to Figure 6 and Figure 7 In one embodiment, the voltage stabilizing member 120 includes a switch section 122, a connection section 124, and a trigger section 126 connected in sequence. The switch section 122 is connected to the trigger section 126 through the connection section 124. In one specific embodiment, the connection section 124 is provided with a first thread structure, and the trigger section 126 is provided with a second thread structure. The trigger section 126 is spirally installed on the connection section 124 through the second thread structure and the first thread structure.

[0063] Please refer to Figure 6 The connection section 124 is movably inserted into the voltage stabilizing channel 1124. The trigger section 126 is arranged in the voltage stabilizing cavity 112, and the switch section 122 is arranged outside the voltage stabilizing cavity 112. The voltage stabilizing member 120 seals and cooperates with the voltage stabilizing channel 1124 through the switch section 122 to block the voltage stabilizing channel 1124. For example, when the gas stove 10 is not working or the air pressure in the voltage stabilizing cavity 112 is small enough, the switch section 122 can seal the voltage stabilizing channel 1124. The sealing method can be that the switch section 122 contacts and cooperates with the inner wall of the voltage stabilizing channel 1124 to block the air outlet of the voltage stabilizing channel 1124.

[0064] During use, the trigger section 126 is driven by force to drive the connection section 124 to drive the switch section 122 to move to adjust the volume of the air outlet gap 130 formed between the switch section 122 and the inner wall of the voltage stabilizing channel 1124. Among them, the power source for driving the trigger section 126 to drive the connection section 124 to move can be the air pressure in the voltage stabilizing cavity 112 or the combined action of the air pressure in the voltage stabilizing cavity 112 and the air pressure outside the voltage stabilizing cavity 112, or it can also be an additional driving mechanism, such as a linear module or a telescopic rod member. Please refer to Figure 6, in this embodiment, the movement of the trigger section 126 is driven by air pressure.

[0065] Based on the foregoing embodiment, please refer to Figure 6 , the pressure stabilizing member 120 further includes an elastomer 128. The elastomer 128 is sleeved on the connecting section 124. One end of the elastomer 128 abuts against the inner wall of the pressure stabilizing cavity 112, and the other end of the elastomer 128 abuts against the trigger section 126. In use, the air pressure in the pressure stabilizing cavity 112 drives the trigger section 126 to move against the restoring force of the elastomer 128, and drives the switch section 122 to move away from the pressure stabilizing cavity 112, and the movement mode is more stable. When the pressure in the pressure stabilizing cavity 112 decreases, under the action of the restoring force of the elastomer 128, the trigger section 126 is driven to drive the switch section 122 to move towards the pressure stabilizing cavity 112. The specific principle is as follows:

[0066] The elastomer 128 has a first state, a second state and a third state. The specific working states of the elastomer 128 are as follows:

[0067] When the elastomer 128 is in the first state, the elastomer 128 is compressed, and the elastomer 128 applies a thrust to the trigger section 126 to make the switch section 122 in sealing fit with the pressure stabilizing channel 1124; the first state can be a state where the air pressure in the pressure stabilizing chamber 110 is small or the gas stove 10 is not working. During assembly, the elastomer 128 is driven to be compressed. After assembly, under the action of the restoring force of the elastomer 128, the trigger section 126 is driven to move to drive the switch section 122 to block the pressure stabilizing channel 1124.

[0068] When the elastomer 128 is in the second state, the trigger section 126 presses against the elastomer 128 and drives the connecting section 124 to drive the switch section 122 to open the pressure stabilizing channel 1124; the second state can be a state where the air pressure in the pressure stabilizing chamber 110 is large enough to release pressure. At this time, under the action of the air pressure in the pressure stabilizing chamber 110, the trigger section 126 is driven to drive the connecting section 124 to move. At this time, the connecting section 124 drives the switch section 122 to open the pressure stabilizing channel 1124 to release pressure.

[0069] When the elastomer 128 is in the third state, the elastomer 128 pushes the trigger section 126 to drive the connecting section 124 to move under the action of the restoring force, so that the switch section 122 moves closer to the pressure stabilizing channel 1124. The third state can be a state where the air pressure in the pressure stabilizing chamber 110 decreases. For example, when the gas stove 10 is used for a long time and the performance of the blower decreases, the air pressure in the pressure stabilizing chamber 110 decreases; at this time, under the action of the restoring force of the elastomer 128, the trigger section 126 is driven to drive the connecting section 124 to move. At this time, the connecting section 124 drives the switch section 122 to move towards the pressure stabilizing cavity 112 to reduce the air output of the pressure stabilizing channel 1124, so as to maintain the air pressure in the pressure stabilizing chamber 110.

[0070] Optionally, the elastomer 128 can be a spring, elastic rubber, or the like.

[0071] Furthermore, when the switch segment 122 moves relative to the pressure stabilizing chamber 110, the air output volume of the pressure stabilizing channel 1124 will change; in other words, when the switch segment 122 moves relative to the pressure stabilizing channel 1124, the volume of the air output gap 130 formed between the switch segment 122 and the pressure stabilizing channel 1124 will change.

[0072] The way to achieve the change in the volume of the air output gap 130 when the switch segment 122 moves can be: the pressure stabilizing channel 1124 is conical, and the cross-sectional area of the pressure stabilizing channel 1124 gradually increases from the air inlet of the pressure stabilizing channel 1124 to the air outlet direction, and the switch segment 122 is strip-shaped. When the switch segment 122 moves away from the pressure stabilizing cavity 112, the volume of the air output gap 130 gradually increases; when the switch segment 122 moves closer to the pressure stabilizing cavity 112, the volume of the air output gap 130 gradually decreases.

[0073] Please refer to Figure 8 , in another embodiment, the pressure stabilizing channel 1124 includes an adjustment section 11242, and the cross-sectional area of the adjustment section 11242 gradually increases along the exhaust direction of the adjustment section 11242. Different from the foregoing embodiment, in this embodiment, the adjustment section 11242 is a partial structure of the pressure stabilizing channel 1124, and the adjustment section 11242 is a structure located at the air outlet of the pressure stabilizing channel 1124. The switch segment 122 seals the pressure stabilizing channel 1124 by contacting and cooperating with the inner wall of the adjustment section 11242.

[0074] Please refer to Figure 7 and Figure 8 , specifically in one embodiment, the shape of the switch segment 122 matches the shape of the adjustment section 11242. In this way, when the switch segment 122 and the adjustment section 11242 are in contact and cooperation, the sealing effect is better.

[0075] For example, please refer to Figure 7 and Figure 8 , in one embodiment, both the shape of the switch segment 122 and the adjustment section 11242 are conical. In this way, when the air pressure in the pressure stabilizing cavity 112 is small, the switch segment 122 has a certain guiding property when moving relative to the adjustment section 11242, which is convenient for the switch segment 122 to reset; further, the compression amount of the elastomer 128 is proportional to the pressure. When the air pressure in the pressure stabilizing cavity 112 becomes small, the compression amount of the elastomer 128 also becomes small. At this time, the displacement of the switch segment 122 moving out is smaller, the volume change of the air output gap 130 is smaller, and thus the air volume discharged is smaller, so as to maintain the air pressure in the pressure stabilizing cavity 112. The specific adjustment principle is as follows:

[0076] When the switch segment 122 moves relative to the adjustment segment 11242 along the air outlet direction of the adjustment segment 11242 (please refer to Figure 5 the L3 direction in

[0077] ), the volume of the air outlet gap 130 formed between the switch segment 122 and the inner wall of the voltage stabilizing channel 1124 gradually increases; at this time, the voltage stabilizing cavity 112 is depressurized to reduce the air pressure in the voltage stabilizing cavity 112 so that the air pressure in the voltage stabilizing cavity 112 remains at a preset value.
