Description

[0001] Cross-referencing

[0002] This application claims priority to Chinese patent application CN202510330554.6, filed on March 19, 2025, entitled “Stove”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This utility model relates to the field of kitchen appliance technology, specifically to a stove. Background Technology

[0004] A cooker's stove, as a type of kitchen appliance, primarily cooks food by supplying heat to pots and pans placed on the burner. If the cooker includes a proportional valve, adjusting its on / off state and opening degree allows for different heat levels, thus enabling more precise cooking of food.

[0005] If the pot is overflowing or about to overflow, the heat should be reduced. Because the combustion power at a low heat setting is still relatively high, especially when overflowing has already occurred or is about to happen and is difficult to prevent, even adjusting to a low heat setting may not suppress or eliminate the overflow. In such cases, turning off the heat is usually necessary to prevent or eliminate the overflow. This will interrupt the cooking process and negatively impact the cooking experience. Utility Model Content

[0006] The present invention aims to solve at least part of the above-mentioned technical problems and / or solve at least part of the above-mentioned technical problems. Specifically, it aims to ensure the cooking performance of the stove without interrupting the current cooking process as much as possible.

[0007] In view of this, the present invention provides a stove, which includes a gas circuit assembly, the gas circuit assembly including a proportional valve assembly, the proportional valve assembly including: a valve body; an inlet valve disposed at the inlet port of the valve body; and at least one outlet valve disposed at at least one outlet port of the valve body; wherein, the valve body is provided with a connecting structure in the passage corresponding to the inlet port and at least one outlet port, so that: when the outlet port is closed, the gas can reach the burner of the stove through the connecting structure.

[0008] This configuration allows the burner of the stove to be prevented from going out even when the gas outlet is closed.

[0009] In one possible implementation of the above-mentioned stove, the connecting structure includes one or more; and / or the connecting structure is provided in the passage in a switchable or normally open manner; and / or the same connecting structure can be connected to the passage of the air inlet valve port and one or more of the air outlet valve ports.

[0010] This configuration provides a possible form for a proportional valve assembly with a connected structure.

[0011] In one possible implementation of the above-mentioned stove, the at least one gas outlet valve includes: a first gas outlet valve; and a second gas outlet valve disposed between the gas inlet valve and the first gas outlet valve; wherein the connecting structure is disposed in the passage between the gas inlet valve and the second gas outlet valve.

[0012] This configuration indicates the location of the connecting structure on the proportional valve assembly.

[0013] In one possible implementation of the above-mentioned stove, the valve body includes: a first passage section arranged along the axial direction of the air intake valve; and a second passage section having an angle with the first passage section; wherein the air intake valve port can be connected to the air outlet valve port sequentially through the first passage section and the second passage section; wherein the connecting structure is arranged in the second passage section.

[0014] With this configuration, it is possible to achieve a gas supply quality corresponding to the interconnected structure that is close to that of the second outlet valve.

[0015] In one possible implementation of the above-mentioned stove, the first passage segment is substantially perpendicular to the second passage segment; and / or the axis of the connecting structure is substantially parallel to the axis of the gas outlet valve.

[0016] This configuration provides a specific way to set up the connectivity structure on the second path.

[0017] In one possible implementation of the above-mentioned stove, when viewed along the gas supply direction of the gas circuit assembly, the connecting structure is located on the valve body near the gas outlet valve port.

[0018] This configuration allows for a further guarantee that the gas supply quality corresponding to the connecting structure is close to that of the second outlet valve.

[0019] In one possible implementation of the above-mentioned stove, the connecting structure is located at a position where the valve body is not split in the middle.

[0020] This configuration allows for better assurance of gas supply quality based on the interconnected structure.

[0021] In one possible implementation of the above-mentioned stove, the cross-sectional dimension of the connecting structure is smaller than the cross-sectional dimension of the gas outlet valve.

[0022] In one possible implementation of the above-mentioned stove, when viewed along the gas supply direction of the gas circuit assembly, the cross-sectional dimension of the downstream side of the connecting structure is greater than or equal to the cross-sectional dimension of the upstream side.

[0023] In one possible implementation of the above-mentioned stove, the connecting structure includes a first connecting segment and a second connecting segment, wherein the first connecting segment is located upstream of the second connecting segment along the gas supply direction of the gas circuit assembly, and wherein the cross-sectional dimension of the second connecting segment is larger than the cross-sectional dimension of the first connecting segment.

[0024] In a preferred embodiment of this invention, a minimum heat setting is created by adjusting the burner's flame intensity via a gas valve and utilizing a connected structure. This allows for the fulfillment of extreme cooking needs while preventing flameout.

[0025] A typical cooktop includes a main on / off valve (capable of switching the connection state of the main gas path of the cooktop's gas circuit components) and at least one proportional valve assembly (capable of adjusting the flame intensity corresponding to the burner of the cooktop). In this way, the intake valve of the proportional valve assembly can switch the connection state between the proportional valve assembly and the upstream main on / off valve, and the outlet valve of the proportional valve assembly can switch the connection state between the proportional valve assembly and the downstream burner. In cases where the burner consists of only one component and the control logic of the proportional valve assembly's intake valve is sufficiently comprehensive, the main on / off valve can be omitted.

[0052] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" 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 direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can still be implemented without certain specific details. In some examples, the detailed structure and principles of stoves well-known to those skilled in the art are not described in detail, in order to highlight the main points of this utility model.

[0054] The following will refer to Figures 1 to 5 This utility model is described by at least a portion thereof.

[0055] Main reference Figure 1 and Figure 2 In one possible implementation, the stove 100 mainly includes a main on / off valve 1, a proportional valve assembly 2, a gas circuit assembly, and at least one burner. The gas circuit assembly supplies gas to the burner. The main on / off valve 1 is typically located on the main gas circuit 31 of the gas circuit assembly and is primarily used to control the overall gas flow in the gas circuit assembly. The proportional valve assembly 2 is located downstream of the main on / off valve 1 along the gas supply direction and is primarily used to adjust the burner's flame intensity.

[0056] In this example, the burner includes three components, as shown below. Figure 1The orientations shown are respectively denoted as the left burner 41, the middle burner 42, and the right burner 43 from left to right. Among them, both the left burner 41 and the right burner 43 have a structural form with two gas paths for gas supply. For example, both the left burner 41 and the right burner 43 include an outer ring and an inner ring. The gas path assembly includes a first gas path (such as an outer ring gas path) and a second gas path (such as an inner ring gas path) corresponding to the outer ring and the inner ring of the left / right burner. In this way, gas can be supplied to the outer ring and the inner ring of the burner via the outer ring gas path and the second gas path respectively. The middle burner 42 has a structural form with one gas path for gas supply. For example, the middle burner 42 includes an inner ring, and the gas path assembly supplies gas to the inner ring of the middle burner 42 through the inner ring gas path corresponding to the middle burner 42. Among them, three burners are respectively equipped with three proportional valve assemblies 2. By the cooperation of the on-off main valve 1 and the proportional valve assembly 2, the firepower of the three burners can be adjusted. Obviously, the number of burners and their gas supply methods can be flexibly selected according to actual needs. For example, the middle burner 42 can also adopt a structural form with two gas paths for gas supply, and the left / right burner can adopt a structural form with one gas path or more than two gas paths for gas supply, etc.

[0057] For example, in this example, the structural forms of the proportional valve assemblies 2 corresponding to the three burners are substantially the same. Obviously, different proportional valve assemblies can also be configured for different burners according to actual needs. For example, the proportional valve assemblies corresponding to the left / right burners and the proportional valve assembly corresponding to the middle burner 42 can be different.

[0058] In this example, the cooker 100 further includes a main control board 5, a display board 6, and a wireless communication module 7. Among them, the main control board 5 is mainly used to issue parameters such as opening / closing the control main valve and the proportional valve assembly 2 to adjust the firepower of the burner. The display board 6 is mainly used to display operating parameters such as the firepower of the burner heads corresponding to the three burners. The wireless communication module 7 (such as a Wi-Fi module, a Bluetooth module, etc.) is mainly used to realize the signal connection between the main control board 5 of the 100 and other data. On this basis, it is expected to realize the linkage between the cooker 100 and other devices. For example, according to the image data (such as for whether the cookware has overflowed or dry burned, etc.) located above the cooker 100 collected by components such as the camera assembly installed on the range hood, by controlling the operating parameters of the cooker 100, the reliability of cooking can be ensured. For example, the image data can be directly transmitted to the main control board 5 through the wireless communication module 7 and analyzed by the main control board 5 of the cooker 100; or the analysis result based on the image data can be transmitted to the main control board 5 of the cooker, and the main control board 5 can directly give corresponding adjustment signals according to the pre-established mapping relationship between the image data and the on-off assembly / proportional valve assembly.

[0059] Mainly refer to Figure 3 and Figure 4In one possible implementation, the proportional valve assembly 2 mainly includes a valve body 21, which has a gas passage that allows gas flow. The valve body 21 has an inlet valve 211 and at least one outlet valve. The inlet valve 211 is equipped with an inlet valve 211, which mainly works in conjunction with the aforementioned on / off main valve 1 to ensure gas intake for the proportional valve assembly 2. The outlet valve is equipped with an outlet valve, and the outlet port can connect to the aforementioned outer or inner ring gas path. The outlet valve mainly adjusts the amount of gas supplied to the burner by regulating the opening degree of the outlet valve, thereby adjusting the burner's flame intensity. In this example, there are two outlet valve ports, which are referred to as the first outlet valve port and the second outlet valve port, respectively. Correspondingly, the outlet valves configured at the first outlet valve port and the second outlet valve port are referred to as the first outlet valve 221 and the second outlet valve 222, respectively. The first outlet port 251 (outer ring outlet port) corresponding to the first outlet valve port can be connected to the outer ring air path. The second outlet valve port is located between the inlet valve 211 and the first outlet valve port. The second outlet port 252 corresponding to the second outlet valve port can be connected to the inner ring air path.

[0060] The valve body 21 has internal passages, including a first passage 231 located between the first and second outlet valve ports and a second passage 232 located between the second outlet valve port and the inlet valve 211 port. In this way, the regulation of the gas in the outer ring gas path corresponding to the first outlet valve port is achieved by the joint regulation of the first outlet valve 221 and the second outlet valve 222, and the regulation of the gas in the inner ring gas path corresponding to the second outlet valve port is achieved by the regulation of the second outlet valve 222.

[0061] Obviously, the description of the pathways, including the first pathway 231 and the second pathway 232 connected in series, is merely an exemplary description; it can also be implemented in other ways, such as through parallel connection. Exemplarily, two first pathways 231 are provided between the intake valve 211 and the first outlet valve. One of these first pathways 231 is connected in parallel with the second pathway 232 and can therefore independently supply gas to the first outlet valve. The other first pathway 231 is similar in structure to the aforementioned one, forming a gas supply path corresponding to the first outlet valve by connecting it in series with the second pathway 232. In this way, the gas can reach the first outlet valve through two paths. Based on this, the gas in the outer ring gas path corresponding to the first outlet valve can be regulated by a combination of independent and coordinated regulation.

[0062] In one possible implementation, a connecting structure 24 is provided on the first passage 231 and / or the second passage 232. The connecting structure 24 can be a connecting hole opened on the valve body 21, a separately added pipe, etc. In this way, even when the main valve 1 and the inlet valve 211 are open, gas can still enter the corresponding gas passage even when the first / second outlet valves are closed, thus ensuring that the burner of the stove still has a certain firepower. For the same passage, the connecting structure 24 can include one or more, for example, using a multi-point arrangement to ensure the gas intake volume or uniformity. The connecting structure 24 can be a normally open structure or a structure with switchable connection states. For example, it can be automatically adjusted in a manner similar to the inlet / outlet valves, or it can be blocked by manual operation / adjustment. For example, it can be manually adjusted once at the factory stage, thus saving mold opening costs. Alternatively, during the usage phase, the connection state of the connecting structure 24 can be switched manually. For example, while ensuring connection, the specific opening degree can be adjusted (e.g., from 100% to 70%) to adjust the firepower of the burner under the corresponding operating conditions.

[0063] The upstream and / or downstream sides of the connecting structure 24 may have one or more connecting ports. If there is one connecting port on both the upstream and downstream sides, the connecting structure 24 can be used to connect to a gas path corresponding to a single outlet valve. If multiple connecting ports are included, it is possible to connect to multiple gas paths through a single connecting structure 24. For example, the downstream side of the connecting structure 24 includes two branches: one branch connects to the outer ring gas path, and the other branch connects to the inner ring gas path.

[0064] In one possible implementation, the connecting structure 24 is disposed on the second passage 232 between the intake valve 211 and the second outlet valve 222, such as a connecting hole section opened on the valve body 21. In this way, when the main valve 1 / intake valve 211 is open and the first / second outlet valve is closed, the gas can reach the inner ring gas path via the second passage 232 and the connecting structure 24 disposed thereon, thus enabling the burner to provide a certain amount of heat. In this example, the connecting structure 24 is disposed in a non-central position of the valve body. Figure 4 It can be seen that the connected structure 24 is located on one side of the midsection position.

[0065] In one possible implementation, the second passage 232 includes a first passage segment 2321 arranged approximately along the axial direction of the intake valve 211, and a second passage segment 2322 forming an angle with the first passage segment 2321. The intake valve 211 port corresponding to the intake valve 211 can sequentially communicate with the second outlet valve port via the first passage segment 2321 and the second passage segment 2322. A connecting structure 24 is disposed in the second passage segment 2322. By placing the connecting structure 24 near the downstream side of the second passage segment 2322, the position communicating with the inner ring gas path is close to the second outlet valve port. This makes the gas flow properties more similar to those when the second outlet valve 222 is open, thereby ensuring the gas supply quality. For example, the connecting structure 24 can be further positioned in the second passage segment 2322 near the second outlet valve port to further ensure the gas supply quality. Furthermore, the combination of the two connecting segments ensures the compact structure within the valve body 21, which has multiple outlet valves. The structural form of the second passage segment 2322 can be reasonably selected based on the structure of the valve body 21, the number of outlet valves, and their relative positions. For example, the second passage segment 2322 can be a straight line and / or a curve. For instance, the second passage segment 2322 can be a broken line composed of straight lines, a combination of multiple curves, or a combination of straight lines and curves. If the connection point with the first passage segment 2321 is a curve, the angle between the first passage segment 2321 and the second passage segment 2322 can be described using the tangent at the connection point.

[0066] In one possible implementation, the first passage segment 2321 and the second passage segment 2322 are substantially perpendicular. As per... Figure 4 The first passage segment 2321 is a vertical passage segment parallel to the axis of the intake valve 211, and the second passage segment 2322 is approximately a horizontal passage segment. The connecting structure 24 is opened approximately along the wall thickness of the first passage segment 2321; therefore, the axis of the connecting structure 24 is approximately parallel to the axis of the second exhaust valve 222. Alternatively, the axis of the connecting structure 24 can be adjusted to a curve or a straight line with a certain angle to the axis of the second exhaust valve 222, depending on actual needs.

[0067] Main reference Figure 4 and Figure 5In one possible implementation, the cross-sectional (radial) dimension of the connecting structure 24 is smaller than the cross-sectional dimension of the gas outlet valve, such as not exceeding 1 / 25 to 1 / 10 of the cross-sectional dimension of the gas outlet valve, for example, not exceeding 1 / 30 of the cross-sectional dimension of the gas outlet valve. In this way, compared to the case where the first / second gas outlet valve is open, the gas flow rate in the gas passage constructed based on the connecting structure 24 is significantly reduced. Therefore, a very low flame setting of the burner can be constructed based on this gas passage, which can serve to prevent flameout during cooking, or ensure cooking reliability while preventing flameout in situations where the gas supply needs to be shut off.

[0068] In one possible implementation, the cross-sectional dimension of the downstream side of the connecting structure 24 is greater than or equal to the cross-sectional dimension of the upstream side. As in this example, the connecting structure 24 includes a first connecting segment 241 on the upstream side and a second connecting segment 242 on the downstream side. The cross-sectional dimensions of the first connecting segment 241 are approximately the same, and the dimension of the downstream side of the second connecting segment 242 is greater than the dimension of the upstream side. As in this example, the upstream side of the second connecting segment 242 (as denoted as the first sub-connecting segment 2421) is approximately a funnel structure, and the downstream side (as denoted as the second sub-connecting segment 2422) is approximately a cylindrical structure. The aforementioned cross-sectional (radial) dimension of the connecting structure 24 being smaller than the cross-sectional dimension of the outlet valve should be understood in accordance with the cross-section of the first connecting segment 241. Wherein, the cross-sectional dimension of the first sub-connected segment 2421 is not greater than 1 / 10 to 1 / 5 of the cross-sectional dimension of the second sub-connected segment 2422 (the maximum cross-sectional dimension of the second connected segment 242). For example, the cross-sectional dimension of the first sub-connected segment 2421 is not greater than 1 / 9 of the cross-sectional dimension of the second sub-connected segment 2422 (the maximum cross-sectional dimension of the second connected segment 242).

[0069] Obviously, the combination of the funnel structure and the cylindrical structure described above is only an exemplary description of the second connecting segment 242. Those skilled in the art can flexibly adjust it according to actual needs, such as including only the funnel structure.

[0070] Based on the above structure, in this example, taking the proportional valve assembly corresponding to the left and right burners as an example, when the intake valve 211 of the main valve 1 and the proportional valve assembly 2 is open, the firepower of the outer ring flame in the left / right burners can be controlled by adjusting the opening of the first outlet valve 221 and the second outlet valve 222. The firepower of the inner ring flame in the left / right burners can be controlled by adjusting the opening of the second outlet valve 222. When the intake valve 211 of the main valve 1 and the proportional valve assembly 2 is open, and both the first outlet valve 221 and the second outlet valve 222 are closed, the connection structure 24 ensures that the inner ring in the left / right burners still has a certain firepower. For the intermediate burner, the first outlet valve 221 can be blocked, or the proportional valve assembly corresponding to the first outlet valve can be adjusted according to actual needs, such as omitting the first outlet valve.

[0071] Accordingly, this utility model also provides a control method for a stove. In one possible embodiment, the control method includes: opening the intake valve 211 of the main on / off valve 1 and the (left / right burner) proportional valve assembly 2, and closing the first outlet valve 221 and the second outlet valve 222 of the proportional valve assembly 2. In this way, based on the arrangement of the connecting structure 24, the inner ring of the burner can still have a certain amount of firepower when the first outlet valve 221 and the second outlet valve 222 of the proportional valve assembly 2 corresponding to it are closed.

[0072] Since the cross-sectional dimension of the connecting structure 24 is much smaller than that of the second gas outlet, the burner's heat setting based on the connecting structure can be called the burner's minimum heat setting. The burner's heat can be adjusted within a larger range according to cooking needs by regulating the first / second gas outlet valve. In extreme situations such as overflowing or impending overflow, the minimum heat setting constructed based on the connecting structure 24 ensures the sustainability of the stove's cooking process; specifically, it adapts to the current cooking needs without extinguishing the flame.

[0073] As can be seen, in the preferred embodiment of this utility model, the inlet valve of the proportional valve assembly can be connected to the main on / off valve, and the proportional valve assembly can be connected to the outer ring / inner ring gas path respectively via the first / second outlet valve, thereby adjusting the proportion of gas output from the outer ring / inner ring gas path to the corresponding burner. By providing a connecting structure in the second passage between the inlet valve and the second outlet valve, it is possible to ensure that the downstream side of the second outlet valve can still be connected to the inlet valve when the first / second outlet valve is closed. Accordingly, the burner can generate a very low heat setting. Specifically, when the main on / off valve is open / the inlet valve is open and the first / second outlet valve is closed, the gas from the main gas path can flow into the inner ring gas path via the inlet valve, the second passage, and the connecting structure. In extreme situations such as overflow or impending overflow, by operating the stove at the very low heat setting, it is possible to eliminate the extreme phenomena of overflow or impending overflow without extinguishing the flame.

[0074] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
