Description

Technical Field

[0001] This application relates to the field of burner technology, and in particular to a burner and a detection method for gas leak detection. Background Technology

[0002] Existing cooktop burners can be categorized into top-intake burners and bottom-intake burners based on their primary air injection method. Top-intake burners require primary air to enter the injection tube from above the cooktop surface. Utilizing top-intake technology, they separately deliver air and fuel into the combustion chamber, resulting in more perfect and efficient combustion. Compared to traditional bottom-intake burners, top-intake burners are more efficient and better meet user needs.

[0003] The existing top-intake burner has a baffle plate in the middle to prevent gas from leaking out from the ejector tube of the blocked nozzle when one of the outer ring nozzles is blocked. However, when the burner is in use, the gas is not mixed evenly and the combustion is not complete. If the nozzle on one side is damaged or blocked and is not detected in time, there may be a risk of gas leakage and a safety hazard.

[0004] Therefore, it is necessary to design a burner with the function of detecting gas leaks. Summary of the Invention

[0005] In view of this, in order to overcome the defects of the prior art, the present invention provides a burner and detection method with gas leakage detection function, which effectively solves the problem of existing top air intake burners. Because the partition plate is set in the middle of the burner head, the gas mixing is uneven and the combustion is not complete. If the nozzle on one side is damaged and cannot be detected in time, it may cause the risk of gas leakage and create safety hazards.

[0013] Preferably, the burner with gas leak detection function further includes a controller and an alarm, the controller and the alarm being electrically connected to the detection component.

[0014] According to a second aspect of the present invention, a detection method is provided, utilizing a burner equipped with a gas leak detection function, the burner being connected to a gas pipeline, the gas pipeline being provided with a regulating valve body, wherein the detection method includes using the burner equipped with the gas leak detection function to open the regulating valve body, so that the burner equipped with the gas leak detection function is in an operating state; the burner head generates a flame, and a detection component detects the temperature of the flame located in the upper part of the first chamber; the detection component feeds back the detected temperature result, and if the temperature is lower than a preset threshold, it is determined that there is a gas leak, and if the temperature is higher than the preset threshold, it is determined that there is no gas leak.

[0015] Preferably, the detection component includes a first temperature detection component and a second temperature detection component. The first temperature detection component is disposed close to the air outlet nozzle, and the second temperature detection component is disposed away from the air outlet nozzle. If the temperatures detected by the first temperature detection component and the second temperature detection component decrease simultaneously, it is determined to be a normal working state. If the temperature decrease detected by the first temperature detection component is small, and the temperature decrease detected by the second temperature detection component is large, it is determined to be a leaking state.

[0016] Preferably, the detection component includes a temperature detection component and a zero-position detection switch. The temperature detection component is disposed in the second chamber, and the zero-position detection switch is disposed in the regulating valve body. When the regulating valve body is at its maximum opening, the temperature detection component operates to detect the temperature of the flame. If the flame temperature detected by the temperature detection component drops significantly, it is determined to be in a leaking state.

[0017] The burner with gas leak detection function according to the present invention improves the burner head structure so that the combustion in the first chamber of the burner head forms a complete ring flame, making the gas mix evenly and the combustion more complete.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] In the description of the embodiments of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] According to a first aspect of the present invention, a burner having a gas leak detection function is provided, such as... Figures 1 to 4 As shown, this burner with gas leak detection function can detect whether there is a gas leak during use, ensuring safe operation. The burner includes a burner head and a detection component.

[0030] In the following description, reference will be made to Figures 1 to 4 The detailed structure of the burner head and detection component of the burner equipped with gas leak detection function is described in detail. Furthermore, in the description of the embodiment, two directions are involved: a first direction S1 and a second direction S2. The first direction S1 can be understood as the length direction of the mounting base 8, and the second direction S2 can be understood as the height direction of the mounting base 8. The first direction S1 can be perpendicular to the second direction S2.

[0031] like Figures 1 to 3 As shown, in this embodiment, the burner head includes a first annular portion 1 and a second annular portion 2, with the second annular portion 2 disposed in the middle of the first annular portion 1. The burner head can be formed into an approximately disc-shaped structure. The first annular portion 1 serves as the main structure of the burner head, has a certain thickness, and has a connecting hole (not shown) at the bottom for connection with the mounting base 8 described below. The second annular portion 2 serves as the inner ring structure of the burner head, allowing the burner head to be divided into an outer ring and an inner ring through the first annular portion 1 and the second annular portion 2. A first chamber 3 is formed between the first annular portion 1 and the second annular portion 2 for storing the mixed gas (fuel gas and air) and supplying gas for the combustion of the outer ring fire. A second chamber 4 is formed inside the second annular portion 2 for storing the mixed gas that supplies gas for the inner ring fire.

[0032] like Figures 1 to 3 As shown, in this embodiment, a detection component is provided on the periphery of the second chamber 4, specifically on the inner periphery. When using a burner with a gas leak detection function, the detection component detects the temperature of the flame (i.e., the outer ring flame) located in the upper part of the first chamber 3 (here, the upper part can be understood as the upper part in the second direction S2, where the mixed gas is stored in the second chamber 4, ejected through the ignition hole of the first burner cap 701, and then ignited by the ignition needle 9 to form a flame).

[0033] In existing technologies, the outer ring flame is larger and requires more mixed gas. Therefore, two ejector tubes and two outlet nozzles (i.e., the two outer ring ejector tubes, the first outlet nozzle 801, and the second outlet nozzle 802) are typically used to supply gas to the outer ring flame. Because the two outlet nozzles are exposed to high temperatures and oily environments for extended periods, they are prone to blockage or damage, leading to reduced gas output and even the risk of leakage. In existing technologies, the burner head uses a partition plate in the middle to prevent gas from leaking out of the ejector tube of the blocked nozzle when one of the two outer ring nozzles becomes blocked. However, burners with partition plates often experience uneven gas mixing and incomplete combustion, failing to form a complete ring. This burner with gas leakage detection utilizes a detection component to determine nozzle blockage by detecting flame temperature. The detection component works as follows: during normal burner operation, taking a 5.2kW burner as an example, the outer ring distribution ratio is generally around 4.2kW, with each of the two outer ring outlet nozzles receiving a load of 2.1kW. When one of the outer ring nozzles becomes blocked, the load drops by half, and the flame height also decreases. At this time, the flame separates from the detection component, the temperature of the detection component drops, and it is judged to be a leak.

[0034] Example 1

[0035] Preferably, in an embodiment, the detection component may include a first temperature detection component and a second temperature detection component, which are disposed opposite to each other on the inner circumferential side of the second annular portion 2 in a first direction S1.

[0036] Specifically, in this embodiment, the first temperature detection component may include at least one first temperature probe 5, and the second temperature detection component may include at least one second temperature probe 6. The number of first temperature probes 5 and second temperature probes 6 may be the same, for example, one, two, three, four, or more. The multiple first temperature probes 5 and multiple second temperature probes 6 are also arranged opposite each other on the inner circumference of the second annular portion 2 in the first direction S1. The multiple first temperature probes 5 and multiple second temperature probes 6 can improve the detection sensitivity, and the user can specifically select the number of first temperature probes 5 and second temperature probes 6 according to specific circumstances, the space of the second annular portion 2, and whether interference with other components is possible.

[0037] like Figures 1 to 3As shown in the embodiment, for ease of description, the number of the first temperature probe 5 and the second temperature probe 6 is one. Specifically, the detection component may include the first temperature probe 5 and the second temperature probe 6, which are disposed opposite to each other on the inner circumference of the second annular portion 2. The first temperature probe 5 and the second temperature probe 6 can be used to detect the flame temperature at both ends of the first chamber 3, and more accurate leakage detection can be achieved through temperature comparison. Specifically, since the user needs to frequently adjust the flame size during use, to prevent misjudgment under normal flame size adjustment, two opposing first temperature probes 5 and second temperature probes 6 are set. If the temperature of both probes drops simultaneously, no judgment is made; if the temperature drop of one temperature probe is larger and the temperature drop of the other temperature probe is smaller, a leakage is judged.

[0038] Preferably, in an embodiment, the burner with gas leak detection function may further include a controller (not shown) and an alarm (not shown), the controller and the alarm being electrically connected to the detection component.

[0039] Specifically, in this embodiment, the first temperature probe 5 and the second temperature probe 6 can both be electrically connected to an external controller (not shown). The controller receives the temperature signals transmitted by the first temperature probe 5 and the second temperature probe 6 and determines whether there is a gas leak. The controller can be, for example, a PLC controller, and can be installed on the panel of the stove. An alarm device can be electrically connected to the controller and the first temperature probe 5 and the second temperature probe 6. It determines whether there is a gas leak by using the first temperature probe 5 and the second temperature probe 6. If there is a gas leak, the alarm device will sound an alarm to alert the user. The alarm device can be, for example, an alarm light and a sound alarm, which can emit light or sound. It should be noted that the first temperature probe 5, the second temperature probe 6, the controller, and the alarm device can all be components in the prior art. Their principles, structures, and connection methods are well known to those skilled in the art and will not be described in detail here. In addition, those skilled in the art can set the controller and electrical connection lines in specific locations as needed.

[0040] Preferably, such as Figure 3 As shown, in this embodiment, the first temperature probe 5 may include a first detection end 501 and a first connection end 502, and the second temperature probe 6 may include a second detection end 601 and a second connection end 602. The first temperature probe 5 and the second temperature probe 6 are formed into an approximately cylindrical structure, and both have two ends in the second direction S2, namely a detection end and a connection end. The detection end is used to detect the flame temperature, and the connection end is used to connect to the aforementioned controller and alarm device.

[0041] The first detection end 501 and the second detection end 601 are inserted through the furnace head in the second direction S2 for detecting flame temperature. The first connection end 502 and the second connection end 602 are located outside the furnace head for easy connection with the aforementioned controller and alarm components.

[0042] Furthermore, during the use of this burner equipped with gas leak detection function, the detection end of the first temperature probe 5 and the detection end of the second temperature probe 6 are both located near the edge of the outer flame of the flame under normal operating conditions (i.e., near the flame hole 703 of the first flame cap 701), which improves the detection quality.

[0043] Preferably, such as Figures 1 to 4 As shown, in this embodiment, an ejector tube (not shown) is provided at the bottom of the burner head, and the ejector tube is connected to the first chamber 3; the burner with gas leakage detection function may also include a mounting base 8, the burner head is disposed on the upper part of the mounting base 8, and the first end of the mounting base 8 in the first direction S1 (e.g., Figure 4 As shown, an exhaust nozzle is provided, and the exhaust nozzle is correspondingly provided with the ejector tube. Specifically, the exhaust nozzle may include an inner ring exhaust nozzle 803 and an outer ring exhaust nozzle. The outer ring exhaust nozzle may include a first exhaust nozzle 801 and a second exhaust nozzle 802. The first exhaust nozzle 801 and the second exhaust nozzle 802 are respectively provided on both sides of the inner ring exhaust nozzle 803. The ejector tube may include an inner ring ejector tube and an outer ring ejector tube. The inner ring ejector tube supplies gas to the inner ring fire of the second chamber 4. The outer ring ejector tube may include two oppositely arranged first outer ring ejector tubes and second outer ring ejector tubes. The first outer ring ejector tube and the second outer ring ejector tube are respectively arranged on both sides of the inner ring ejector tube (corresponding to the positions of the first gas outlet nozzle 801, the second gas outlet nozzle 802, and the inner ring gas outlet nozzle 803). Both the first outer ring ejector tube and the second outer ring ejector tube can supply gas to the first chamber 3. Since the first outer ring ejector tube and the second outer ring ejector tube are arranged oppositely on both sides of the burner head formed in a disc shape, each outer ring ejector tube can supply gas to half of the first chamber 3, and the inner ring ejector tube can supply gas to the second chamber 4.

[0044] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the ejector tube includes a first ejector tube (i.e., a first outer ring ejector tube) and a second ejector tube (i.e., a second outer ring ejector tube) arranged opposite to each other. The exhaust nozzle may include a first exhaust nozzle 801 and a second exhaust nozzle 802 arranged opposite to each other. The first exhaust nozzle 801 is arranged opposite to the first ejector tube, and the second exhaust nozzle 802 is arranged opposite to the second ejector tube. The first chamber 3 has two opposite air inlets 301 (only one is shown due to perspective), and the two opposite air inlets 301 are respectively connected to the first ejector tube and the second ejector tube. Through the air inlets 301, each outer ring ejector tube can supply air to half of the first chamber 3.

[0045] Preferably, such as Figures 1 to 3 As shown in the embodiment, the burner with gas leak detection function may further include a first flame cap 701 and a second flame cap 702. The first flame cap 701 and the second flame cap 702 may be respectively installed on the first chamber 3 and the second chamber 4. Both the first flame cap 701 and the second flame cap 702 may have flame holes 703. The mixed gas in the first chamber 3 and the second chamber 4 can be ejected through the flame holes 703 and ignited by the ignition needle 9 and the thermocouple 10 to produce a flame.

[0046] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the burner head may also include a gas distribution plate 704, which may be installed on the top of the first chamber 3 and realize the diversion and regulation of the gas inside the first chamber 3.

[0047] Preferably, such as Figures 1 to 3 As shown, in the embodiment, the mounting base 8 may further include an inner ring air inlet nozzle 804 and an outer ring air inlet nozzle 805. The inner ring air inlet nozzle 804 is connected to the inner ring air outlet nozzle 803, and the outer ring air inlet nozzle 805 is connected to the first air outlet nozzle 801 and the second air outlet nozzle 802.

[0048] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the first temperature probe 5 is positioned close to the outlet nozzle in the first direction S1, while the second temperature probe 6 is positioned far from the outlet nozzle in the first direction S1. The first temperature probe 5 and the second temperature probe 6 are positioned at different locations, enabling more accurate detection. Thus, when the temperature drop detected by the second temperature probe 6 is larger than the temperature drop detected by the first temperature probe 5, a leak is determined.

[0049] Example 2

[0050] This burner with gas leak detection function can be connected to a gas pipeline (not shown). The gas pipeline is equipped with a regulating valve body (not shown). The user can adjust the gas intake by adjusting the regulating valve body, thereby controlling the flame size of the burner with gas leak detection function. The detection component can include a temperature detection component and a zero-position detection switch (not shown). The temperature detection component is located on the inner circumference of the second annular portion 2, and the zero-position detection switch is located on the regulating valve body. The zero-position detection switch and the temperature detection component are electrically connected. When the regulating valve body is at its maximum opening, the temperature detection component performs a detection and simultaneously sets a threshold value for a standard range, for example, 800 degrees Celsius to 1000 degrees Celsius. Temperatures within the threshold value indicate a normal state; temperatures below the threshold value indicate a gas leak.

[0051] Specifically, in this embodiment, the temperature detection component can be, for example, a temperature probe. The number of temperature probes can be one or more. Multiple temperature probes can improve detection sensitivity. The user can select the number of temperature probes based on specific circumstances, the space of the second annular portion 2, and whether it interferes with other components. In this embodiment, for ease of description, a single temperature probe is used.

[0052] Preferably, in this embodiment, the temperature probe and the zero-position detection switch can both be electrically connected to an external controller (not shown) and an alarm device (not shown). The controller receives the temperature signal transmitted by the zero-position detection switch, controls the temperature probe to perform temperature detection when the switch is at its maximum opening, and determines whether there is a leak based on the temperature. The alarm device is used to alert the user that there is a leak. It should be noted that the temperature probe, zero-position detection switch, controller, and alarm device can all be components from the prior art, and their principles, structures, and connection methods are well known to those skilled in the art and will not be described in detail here. Furthermore, those skilled in the art can arrange the controller, alarm device, zero-position detection switch, and electrical connection wires in specific locations as needed.

[0053] This burner, equipped with gas leak detection, improves the burner head structure so that the combustion in the first chamber of the burner head forms a complete ring flame, resulting in uniform gas mixing and more complete combustion. At the same time, to prevent gas leaks, the detection components monitor the flame temperature in real time, improving combustion efficiency while ensuring safety and avoiding potential safety hazards.

[0054] Furthermore, according to a second aspect of the present invention, a detection method is provided, which can utilize a burner with a gas leak detection function as described above. The detection method includes:

[0055] The first step is to use a burner with gas leak detection function, open the regulating valve body to put the burner with gas leak detection function into working condition;

[0056] The second step is that the burner produces a flame, and the detection component detects the temperature of the flame located in the upper part of the first chamber 3. The detection component reports the detected temperature result. If the temperature is lower than the preset threshold, it is judged as a gas leak. If the temperature is higher than the preset threshold, it is judged as no gas leak.

[0057] Preferably, in one embodiment, the detection component may include a first temperature detection component and a second temperature detection component, with the first temperature detection component disposed close to the outlet nozzle and the second temperature detection component disposed away from the outlet nozzle. If the temperatures detected by the first and second temperature detection components decrease simultaneously, it is determined to be a normal operating state; if the temperature decrease detected by the first temperature detection component is small and the temperature decrease detected by the second temperature detection component is large, it is determined to be a leaking state.

[0058] The first temperature detection component may include at least one first temperature probe 5, and the second temperature detection component may include at least one second temperature probe 6. The first temperature probe 5 is disposed close to the exhaust nozzle, and the second temperature probe 6 is disposed away from the exhaust nozzle. Thus, the specific detection steps are as follows:

[0059] When the temperatures detected by the first temperature probe 5 and the second temperature probe 6 decrease simultaneously, it is considered a normal working condition.

[0060] If the temperature drop detected by the first temperature probe 5 is small, while the temperature drop detected by the second temperature probe 6 is large, then there is a leak.

[0061] Preferably, the controller can compare the signals detected by the first temperature probe 5 and the second temperature probe 6 to determine whether there is a leak, and then feed the result back to the user. The feedback method can be, for example, by connecting an alarm device.

[0062] Preferably, in another embodiment, the detection component may include a temperature detection component and a zero-position detection switch. The temperature detection component is disposed in the second chamber 4, and the zero-position detection switch is disposed in the regulating valve body. When the regulating valve body is at its maximum opening, the temperature detection component operates to detect the flame temperature; if the flame temperature detected by the temperature detection component drops significantly, it is determined to be a leak.

[0063] To avoid misjudgment, the temperature probe operates and detects the flame temperature when the regulating valve is at its maximum opening. The temperature detection assembly may include at least one temperature probe, and the specific detection steps are as follows:

[0064] If the flame temperature detected by the temperature probe drops significantly, it indicates a gas leak. The detection component will provide feedback on the detection results. The controller can then control the temperature probe and the zero-position detection switch, compare and judge the signals detected by the temperature probe, and finally provide feedback to the user. Feedback can be provided, for example, by connecting an alarm device.

[0065] This detection method can accurately and conveniently detect whether the burner is leaking gas, and can provide timely structural feedback. Users do not need to perform any additional operations to detect leaks, making it convenient and quick.

[0066] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
