Abstract
Description
[0001] 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
[0002] This application relates to the field of kitchen appliance technology, specifically to a control method for a stove. Background Technology
[0003] A cooktop, as a type of kitchen appliance, primarily cooks food by supplying heat to pots and pans placed on the burner. A cooktop typically includes a burner and a gas circuit assembly. The gas circuit assembly contains control valves such as proportional valves. By adjusting the on / off state and opening degree of these proportional valves, the burner can achieve different heat levels, thus enabling better cooking of the food.
[0004] Corresponding to the adjustment of the heat level, control panels such as knobs and buttons are provided on the cooktop. Different heat levels can be adjusted by pressing or rotating these control panels. To ensure the functionality of pressing and rotating, a pressure-stop structure is required on the control panel. However, with increasing demands for adjustment precision and user experience, there is still room for improvement in the user experience and reliability of these control panels. For example, traditional control panels may suffer from insufficient tactile feedback, susceptibility to damage from excessive pressing, and low operational precision. Summary of the Invention
[0005] This application aims to solve at least part of the above-mentioned technical problems and / or at least part of the above-mentioned technical problems, specifically, how to improve the performance of the operating terminal in terms of user experience, reliability and / or operating accuracy as much as possible.
[0006] In view of this, this application provides a control method for a stove, the stove including an operating terminal and an coded switch assembly, the coded switch assembly including a pressure stop assembly, the pressure stop assembly including: a pressure stop base; and a pressure stop valve stem capable of forming a pressure stop space with the pressure stop base, the pressure stop valve stem having an extended end; wherein, the pressure stop base has a first pressure stop engagement feature at a position corresponding to the pressure stop space, the first pressure stop engagement feature including an axial portion and a circumferential portion; the control method includes: moving the extended end along the axial portion so that: the extended end enters the circumferential portion via the axial portion; and moving the extended end along the circumferential portion so that: the operating parameters of the stove are adjusted.
[0007] In this way, a fit can be achieved between the protruding end and the first pressing stop fitting feature within the pressing stop base, realizing a combined pressing and rotating motion of the pressing stop valve stem. Based on this, by limiting the two ends of the circumferential portion, circumferential limiting of the pressing stop assembly can be achieved. Furthermore, by pressing and rotating the operating end (such as a knob) of the stove located on the pressing stop valve stem, the operating parameters of the stove can be adjusted.
[0008] Specifically, the rotation angle of the circumferential portion of the extended end has a preset correspondence with the opening (gap) between the valve and the valve body on the regulating valve (such as a proportional valve assembly). Since the opening between the valve and the valve body of the regulating valve has a preset correspondence with the gas flow rate and the operating parameters of the stove, such as the firepower of the stove (the general trend is: the larger the opening, the larger the gas flow rate and the larger the firepower / firepower level), the operating parameters of the stove can be adjusted by rotating the extended end along the circumferential portion.
[0009] When the extended end enters the circumferential section and reaches a preset position under the action of external force (pressure), the gas can be ignited. Then, by applying further external force (rotational force) to the operating end, the stove's heat can be adjusted. The stove's heat can be adjusted manually or automatically. For example, in manual operation, the stove can be switched on / off and the heat adjusted by manually pressing / rotating the operating end. In automatic operation, if an image acquisition component, such as a camera, is installed above the stove (e.g., on a range hood), and the image acquisition component detects that the pot above the stove is in a state of overflowing or about to overflow, the stove's heat can be reduced to quickly suppress or eliminate the current situation.
[0010] It is understood that those skilled in the art can determine the structural form of the pressing stop base / first pressing stop mating feature, the number of its components, etc., according to actual needs. For example, the protruding end may include one or more protrusions, which may be columnar structures, strip structures, etc. Furthermore, those skilled in the art can determine the structural form of the axial / circumferential portion of the first pressing stop mating feature, the arc length of the circumferential portion, the specific limiting method of the circumferential portion, etc., according to actual needs. For example, the arc length of the circumferential portion can be determined according to the rotation range required in actual needs. At the two ends corresponding to the rotation range of the circumferential portion, the reliability of the circumferential stop can be ensured by the cooperation of limiting structures such as limiting blocks, limiting plates, and limiting strips with the protruding end.
[0011] In one possible implementation of the control method for the above-mentioned stove, the pressure stop assembly includes: an elastic component disposed in the pressure stop space; the phrase "moving the protruding end along the axial portion so that: the protruding end enters the circumferential portion via the axial portion" includes: causing the protruding end to overcome the elastic force of the elastic component and move along the axial portion so that: the protruding end enters the circumferential portion via the axial portion.
[0012] It is understood that those skilled in the art can determine the structural form of the elastic component and its setting method in the downward stop space according to actual needs. For example, the elastic component may include one or more springs, and the spring (outline) may be a columnar structure, a frustum structure, etc. The elastic component may be directly or indirectly connected to the downward stop base / downward stop valve stem. For example, a limit structure may also be configured to ensure the direction of the elastic component under the action of external force.
[0013] In one possible implementation of the control method for the aforementioned stove, the downward pressure stop assembly includes: a fixed member disposed on the downward pressure stop valve stem; an elastic component disposed between the fixed member and the downward pressure stop base; wherein the fixed member is an annular structure, and the annular structure has or forms a first limiting structure along its radially outer side; in the step of "causing the protruding end to overcome the elastic force of the elastic component and move along the axial portion so that: the protruding end enters the circumferential portion via the axial portion", the elastic component is compressed along with the sliding engagement between the first limiting structure and the downward pressure stop base or a second limiting structure disposed on the downward pressure stop base.
[0014] This configuration aims to reduce friction during the rotation of the downward-pressing stop valve stem, thereby reducing wear on the valve stem and the elastic component. Similar to the first downward-pressing stop, the first limiting structure may include one or more protrusions, which can be columnar, strip-shaped, or similar. Correspondingly, the second limiting structure that mates with it can be a groove, track, or similar. Even without the first limiting structure on the fixing member, the presence of the fixing member alone can effectively reduce wear on the downward-pressing stop valve stem and the elastic component.
[0015] In one possible implementation of the control method for the above-mentioned stove, the downward pressure stop valve rod includes a tabletop, the tabletop having a protruding end provided or formed along its radial outer side, and the fixing member being disposed on the lower surface of the tabletop.
[0016] This configuration provides a specific form for the fixing member to be positioned on the downward pressure stop valve stem, such as the radial dimension of the platform being larger than the radial dimension of other (adjacent) parts of the pressure stop valve body. If the platform and the downward pressure stop valve stem are integrally formed, it can also be understood as a platform with a ring-shaped structure extending outward circumferentially at the position of the downward pressure stop valve stem corresponding to the fixing member.
[0017] In one possible implementation of the control method for the above-mentioned stove, the pressure-stop base is provided with a second pressure-stop engagement feature on the side near the pressure-stop valve rod, and the pressure-stop valve rod can abut against the second pressure-stop engagement feature under the action of external force.
[0018] This configuration effectively prevents excessive pressure on the operating end. For example, the second pressure stop feature can be the bottom plane of the pressure stop base, an annular structure extending upwards (towards the pressure stop valve stem) from the bottom of the pressure stop base, or a combination of multiple arc-shaped / block-shaped structures (circumferentially distributed along the pressure stop valve stem). The structural form of the second pressure stop feature can be flexibly designed according to the specific limits of excessive pressure.
[0019] In one possible implementation of the control method for the above-mentioned stove, the pressure stop base includes: a pressure stop base; and a pressure stop housing disposed on the pressure stop base; wherein the second pressure stop mating feature is disposed on or formed on the pressure stop base.
[0020] This configuration provides a possible arrangement of the second downward-pressing stop fitting feature on the downward-pressing stop base. Based on this, by detachably setting the downward-pressing stop base at the target position, the applicable scenarios of the downward-pressing stop assembly can be broadened through a modular arrangement.
[0021] It is understood that those skilled in the art can determine the structural form of the pressure stop base, its connection method with the pressure stop housing and the pressure stop base, and its connection method at the target position according to actual needs. For example, the pressure stop housing and the pressure stop base, or the pressure stop base and the target position in application scenarios such as the stove (the housing of the display panel assembly), can be fixedly connected by fasteners such as screws, or fixedly connected by various connection methods such as snap-fit and screw connection.
[0022] In one possible implementation of the control method for the aforementioned stove, the pressure-stop housing includes a first pressure-stop housing and a second pressure-stop housing arranged axially, and the pressure-stop valve stem includes a first valve stem, a second valve stem, and an intermediate valve stem located between the two.
[0023] Wherein, at least a portion of the intermediate valve stem can be freely accommodated in the first pressure stop housing, the second valve stem is accommodated in the pressure stop space, and the second valve stem can abut against the second pressure stop engagement feature under the action of external force.
[0024] It is understood that those skilled in the art can determine the structural form of the first / second pressure stop housing and the specific way in which the two constitute the pressure stop housing according to actual needs. For example, the first / second pressure stop housing can be roughly cylindrical. The cross-sectional shape of the cylindrical structure at different axial positions can be the same or different. The axial length of the cylindrical structure can be flexibly selected according to actual needs. The first / second pressure stop housing can be formed by fixed connection or integral molding.
[0025] For example, an operating terminal such as a knob on a stove can be connected to the first valve stem, and an coded switch can be connected to the second valve stem. As mentioned above, the countertop is located on the second valve stem near the middle valve stem. It is understood that those skilled in the art can determine the structural form of the first / second / middle valve stem and its connection method at the target position according to actual needs. For example, the target positions in application scenarios such as the pressure stop housing and the pressure stop base, and the pressure stop base and the stove (the housing of the display panel assembly) can be fixedly connected by fasteners such as screws, or by various connection methods such as snap-fit and screw connection.
[0026] In one possible implementation of the control method for the aforementioned stove, at least a portion of the structure of the downward pressure stop assembly is made of metal.
[0027] This design ensures the reliability of the downward pressure stop assembly, effectively avoiding problems inherent in traditional injection-molded parts, such as the ease with which the stop structure can be damaged during forceful rotation, leading to stop failure. It should be noted that the metal material mentioned here can be any suitable material; it should be understood as a replacement of a different type of material, not necessarily an improvement to the material itself. In other words, any existing metal material, or a reasonably selected new metal material, can be used as the material for the downward pressure stop assembly.
[0028] It should be noted that the material was changed because, in this application, the pressing and stopping functions are integrated into one unit, thus enabling both functions to be performed by a single mating part. In this scenario, considering reliability, the traditional injection-molded part is replaced with a metal structure to ensure the reliability of the pressing and stopping assembly while guaranteeing the pressing and stopping function. For example, the service life of a traditional pressing and stopping assembly is approximately 10,000 cycles, while the service life of the pressing and stopping assembly in this application can reach 30,000 to 50,000 cycles.
[0029] In a preferred embodiment of this application, the stop during rotation is achieved by the engagement of the protruding end of the pressure-stop valve rod with a first pressure-stop engagement feature on the pressure-stop base. The stop during pressing is achieved by the engagement of the pressure-stop valve rod with a second pressure-stop engagement feature on the pressure-stop base. Based on this, clear tactile feedback can be provided during user operation, allowing the user to accurately perceive the operating status and improving the user experience. Furthermore, the design of the second pressure-stop engagement feature can prevent operational problems such as over-pressing or misoperation, thereby reducing the risk of damage to the pressure-stop assembly and extending its service life.
[0030] The downward pressure stop assembly of this application can provide precise operation control based on mechanical control, which can meet the requirements of high-precision operation. Based on a modular design, the downward pressure stop assembly of this application can be installed in other scenarios besides the stoves mentioned in this application, such as medical equipment, consumer electronics, automotive electronics, and industrial automation.
[0031] In one possible implementation of the control method for the aforementioned stove, the stove includes a gas circuit assembly, which includes a proportional valve assembly. The proportional valve assembly includes: 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. The phrase "moving the extended end along the circumferential portion to adjust the operating parameters of the stove" includes: moving the extended end along the circumferential portion to adjust the position of the inlet valve relative to the inlet port and / or the position of the outlet valve relative to the outlet port, thereby adjusting the operating parameters of the stove.
[0032] With this configuration, it is possible to adjust the stove's operating parameters, such as firepower, by adjusting the position of the inlet / outlet valves relative to the inlet / outlet valve ports of the proportional valve assembly.
[0033] When a pot overflows or is about to overflow, the heat should be reduced. Because even at a low heat setting, the combustion power is still relatively high, especially when overflow has already occurred or is about to occur 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 suppress or eliminate the overflow. This interrupts the cooking process and negatively impacts the cooking experience. Based on this, this application also includes the following improvements to the stove:
[0034] In one possible implementation of the control method for the above-mentioned stove, the valve body is provided with a connecting structure in the passage corresponding to the air inlet valve port and at least one of the air outlet valve ports. The phrase "moving the extended end along the circumferential portion to: adjust the position of the air inlet valve relative to the air inlet valve port and / or the position of the air outlet valve relative to the air outlet valve port, thereby: adjusting the operating parameters of the stove" includes: moving the extended end along the circumferential portion to: close the air outlet valve relative to the air outlet valve port, and the gas reaches the burner of the stove through the connecting structure.
[0035] This configuration allows the burner of the stove to be prevented from going out even when the gas outlet is closed.
[0036] In one possible implementation, the connecting structure includes one or more; and / or the connecting structure is arranged in the passage in a switchable connected state or normally open manner; and / or the same connecting structure can communicate with the passage of the intake valve port and one or more of the outlet valve ports. This configuration provides a possible form in which the connecting structure constitutes a proportional valve assembly.
[0037] In one possible implementation, the at least one outlet valve includes: a first outlet valve; and a second outlet valve disposed between the inlet valve and the first outlet valve; wherein the connecting structure is disposed in the passage between the inlet valve and the second outlet valve. This configuration indicates the location of the connecting structure on the proportional valve assembly.
[0038] In one possible implementation, the valve body includes: a first passage section disposed along the axial direction of the intake valve; and a second passage section forming an angle with the first passage section; wherein the intake valve port is sequentially connected to the outlet valve port via the first passage section and the second passage section; wherein the connecting structure is disposed in the second passage section. With this configuration, the air supply quality corresponding to the connecting structure can be made to be close to that of the second outlet valve port.
[0039] In one possible implementation, the first passage segment and the second passage segment are substantially perpendicular; and / or the axis of the connecting structure is substantially parallel to the axis of the exhaust valve. This configuration provides a specific arrangement of the connecting structure in the second passage.
[0040] In one possible implementation, viewed along the direction of air supply to the gas path assembly, the connecting structure is positioned on the valve body near the outlet valve port. This configuration further ensures that the air supply quality corresponding to the connecting structure is similar to that of the second outlet valve port.
[0041] In one possible implementation, the connecting structure is located at a position outside the central section of the valve body. This configuration allows for better assurance of gas supply quality based on the connecting structure.
[0042] In one possible implementation, the cross-sectional dimension of the connecting structure is smaller than the cross-sectional dimension of the outlet valve; and / or, when viewed along the direction of air supply to the air passage 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.
[0043] In one possible implementation, 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 path assembly, and wherein the cross-sectional dimension of the second connecting segment is larger than the cross-sectional dimension of the first connecting segment.
[0044] 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.
[0045] Based on this structure, by utilizing the circumferential rotation of the operating end, with the intake valve open and the exhaust valve closed, the gas flows through the valve body's passage and the connecting structure within the passage to the burner of the stove. In this way, by adjusting the burner's flame intensity through the exhaust valve, a very low flame setting is created based on the connecting structure. This allows for cooking in extreme conditions, such as overflowing or near-overflowing, while preventing flameout. Attached Figure Description

[0090] Preferred embodiments of this application will now be described with reference to the accompanying drawings.

[0092] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," 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 application according to the specific circumstances.
[0093] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application 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 application.
[0094] The following will refer to Figures 1 to 13 This application is to be described in at least a portion thereof.
[0095] 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.
[0096] In this example, the burner includes three components, as shown below. Figure 1The locations shown, from left to right, are designated as left burner 41, middle burner 42, and right burner 43. Both left burner 41 and right burner 43 have a dual-gas-path supply structure. Each burner includes an outer ring and an inner ring. The gas path assembly includes a first gas path (which may be called the outer ring gas path) and a second gas path (which may be called the inner ring gas path) corresponding to the outer and inner rings of the left / right burners, respectively. This allows fuel gas to be supplied to the outer and inner rings of the burners via the outer and second gas paths, respectively. The middle burner 42 has a single-gas-path supply structure. If the middle burner 42 includes an inner ring, the gas path assembly supplies gas to the inner ring of the middle burner 42 via the corresponding inner ring gas path. Each of the three burners is equipped with a proportional valve assembly 2. By coordinating the on / off state of the main valve 1 and the proportional valve assemblies 2, the flame intensity of the three burners can be adjusted. Obviously, the number of burners and their gas supply method can be flexibly selected according to actual needs. For example, the middle burner 42 can also adopt a structure with two gas supply lines, and the left / right burners can adopt a structure with one gas supply line or more than two gas supply lines.
[0097] In this example, the proportional valve assemblies 2 corresponding to the three burners have roughly the same structure. 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.
[0098] In this example, the cooktop 100 also includes a main control board 5, a display panel assembly 6, and a wireless communication module 7. The main control board 5 is primarily used to issue parameters such as opening / closing the main control valve and the proportional valve assembly 2 to adjust the burner's heat output. The display panel assembly 6 is primarily used to display operating parameters such as heat output corresponding to the three burner heads on the cooktop's display area (which may only display or include interactive functions such as parameter adjustment). The wireless communication module 7 (such as a Wi-Fi module, Bluetooth module, etc.) is primarily used to establish signal connections between the main control board 5 and other data sources. Based on this, it is expected to enable linkage between the cooktop 100 and other devices. For example, image data collected above the cooktop 100 from components such as a camera mounted on the range hood (e.g., to check for overflowing or dry burning of the pot) can be used to control the cooktop 100's operating parameters, ensuring reliable cooking. Image data can be directly transmitted to the main control board 5 via the wireless communication module 7 for analysis by the main control board 5 of the stove 100; alternatively, the analysis results based on the image data can be transmitted to the main control board 5 of the stove, and the main control board 5 can directly provide the corresponding adjustment signal according to the pre-established mapping relationship between the image data and the on / off assembly / proportional valve assembly.
[0099] Main reference Figure 3 and Figure 4 In 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.
[0100] 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.
[0101] 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.
[0102] 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.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] 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).
[0109] 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.
[0110] 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.
[0111] 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.
[0112] As can be seen, in the preferred embodiment of this application, 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 / inner ring gas path via the first / second outlet valve, thereby adjusting the proportion of gas output from the outer / 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, 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.
[0113] In one possible implementation, the cooktop 100 has a display area on its surface corresponding to the display panel assembly 6. This display area can show information related to the current cooking process, such as the cooktop's heat level and cooking type. The cooktop also has an operating end 8, such as a knob, within the area corresponding to the display area. A pressure-stop assembly 9 is positioned below the operating end 8. The user can adjust the heat level of the corresponding burner by pressing and rotating the operating end. The cooperation between the operating end 8 and the pressure-stop assembly 9 enables the aforementioned pressing and rotating operations. The display area may have a mounting position for the operating end, such as a through hole. The display panel assembly 6 includes a display panel housing and a display panel disposed within the housing. A light-emitting component is provided on the display panel. The light emitted by the light-emitting component can reach the display area through the light-transmitting display panel housing and corresponding light guides / focusers to achieve the corresponding display function. The pressure-stop assembly 9 is fixedly mounted on the display panel housing.
[0114] Main reference Figures 6 to 8 In one possible implementation, the pressure-stop assembly 9 mainly includes a pressure-stop base 91 and a pressure-stop valve stem 92, forming a pressure-stop space 93. The pressure-stop valve stem 92 has an extended end 925. The pressure-stop base 91 has a first pressure-stop engaging feature 94 at a position corresponding to the pressure-stop space. The first pressure-stop engaging feature 94 mainly engages with the extended end 925 to allow for pressing and rotating movements of the operating end while limiting the rotational movement. The bottom of the pressure-stop base 91, near the pressure-stop valve stem 92, has a second pressure-stop engaging feature 95. The second pressure-stop engaging feature 95 mainly engages with the bottom of the pressure-stop valve stem 92 to limit the pressing movement, effectively preventing excessive pressing of the operating end.
[0115] In one possible implementation, the first pressing stop fitting feature 94 mainly includes an axial portion 941 and a circumferential portion 942. The axial portion 941 is generally a strip-shaped groove along the vertical direction, and the circumferential portion is generally an arc-shaped groove distributed in the horizontal plane. The lower end of the strip-shaped groove communicates with the arc-shaped groove. Based on this, the protruding end 925 can move downward along the strip-shaped groove under the action of an external force, and after entering the arc-shaped groove, it can rotate along the arc-shaped groove under the action of an external force. In this example, the inner wall of the pressing stop housing, corresponding to the positions of the two ends of the arc-shaped groove, can limit the rotational movement.
[0116] In this example, the pressure stop base 91 includes a pressure stop base 911 and a pressure stop housing 912 disposed on the pressure stop base 911. The pressure stop base 911, the pressure stop housing 912, and the lower part of the pressure stop valve stem 92 enclose a pressure stop space 93. In this example, the second pressure stop mating feature 95 is the upper surface of the pressure stop base 911 or an annular structure disposed on the pressure stop base 911. The lower end of the pressure stop valve stem 92 can abut against the second pressure stop mating feature 95 under the action of external force, thereby playing a pressing and limiting role and thus avoiding phenomena such as over-pressing.
[0117] In this example, the downward-pressing stop base 911 is provided with two sets of base mounting structures (referred to as the first set of downward-pressing stop base mounting structures and the second set of downward-pressing stop base mounting structures, respectively). Both the first and second sets of downward-pressing stop base mounting structures include a pair of mounting holes, and the lines connecting the two pairs of mounting holes are approximately diagonally distributed. The first set of downward-pressing stop base mounting structures is used to connect to the downward-pressing stop housing, and the second set of downward-pressing stop base mounting structures is used to connect to a target location, such as the display panel housing of a stove. In this example, the downward-pressing stop base and the downward-pressing stop housing can be fixed together by using fasteners such as screws in conjunction with the first set of downward-pressing stop base mounting structures, and the downward-pressing stop assembly can be fixed to the target location by using fasteners such as self-tapping screws in conjunction with the second set of downward-pressing stop base mounting structures. Clearly, the structural form of the base mounting structure and its specific connection method can be flexibly adjusted according to actual needs.
[0118] Besides cooktops, the target location can also be on devices in other fields such as consumer electronics, medical equipment, and automotive electronics. It can be adapted to meet the needs of different target locations based on actual requirements. Based on its current modular structure, it can be flexibly installed on any operating end requiring both pressing and rotation.
[0119] In one possible implementation, the pressure stop assembly 9 includes an elastic component 96. In this example, the elastic component is a spring wound around the pressure stop valve stem near its lower end and housed within the pressure stop space. The upper and lower ends of the spring are fixedly disposed inside the pressure stop valve stem and the pressure stop base, respectively. When no external force is applied to the operating end, the bottom end of the pressure stop valve stem is at its highest point (first height) under the preload of the elastic component. The second pressure stop engagement feature defines a second height where the bottom end of the pressure stop valve stem is at its lowest point. The height difference between the first and second heights can be flexibly adjusted according to actual needs.
[0120] It can be seen that, under the condition that no external force is applied to the operating end, the downward stop space is a partially open area between the bottom end of the downward stop valve stem and the second downward stop mating feature. When pressed down to the limit position, the open area is blocked. In other words, the downward stop space mentioned here is a general space in which the downward stop base is provided with features such as the first / second downward stop mating features and elastic components. The specific form and closed state of the space will be adjusted according to the state of the operating end.
[0121] In this way, when an external force (pressing force) is applied to the operating end, the protruding end on the downward stop valve stem extends into the axial part after overcoming the elastic force of the elastic component and moves along the axial part. After entering the circumferential part, it rotates along the circumferential part under the action of an external force (rotational force).
[0122] In this example, the pressure stop housing 912 includes an upper first pressure stop housing 9121 and a lower second pressure stop housing 9122 arranged axially. The pressure stop valve stem 92 includes a first valve stem 921, a second valve stem 922, and an intermediate valve stem 923 located between them. In this example, the second valve stem 922 and the intermediate valve stem 923 are cylindrical structures, and the inner diameter of the intermediate valve stem 923 is smaller than that of the second valve stem. The upper first valve stem is used to connect to the aforementioned operating end. The coded switch passes through the lower second valve stem and connects to the intermediate valve stem. Positioning structures (stop surfaces) such as planes are machined on the outer wall of the first valve stem and the inner wall of the intermediate valve stem to ensure the reliability of the pressure stop connection. At least a portion of the intermediate valve stem can be freely accommodated within the first pressure stop housing. When an external force is applied to the operating end, the intermediate valve stem moves downward along the first pressure stop housing. When the external force is removed, the intermediate valve stem moves upward along the first pressure stop housing. The second pressure stop housing, the second valve stem, and the pressure stop base form a pressure stop space.
[0123] For example, the upper part of the first valve stem is connected to the operating end, and the lower end of the middle valve stem is connected to an coded switch. If the inner wall of the cylindrical structure of the middle valve stem is machined with a stop surface to match the structure of the lower end of the middle valve stem, the outer wall of the coded switch valve stem is approximately a columnar structure with a stop surface. The pressure stop base is then fixedly connected to the coded switch mounting box by means of fasteners such as self-tapping screws, and the coded switch and the coded switch mounting box are fixedly connected by fasteners such as screws.
[0124] In this example, the first pressing stop housing 9121 is generally cylindrical, and the second pressing stop housing 9122 is also generally cylindrical. The inner wall of the second pressing stop housing has a stepped surface near the top (where it connects with the base of the pressing stop housing). Correspondingly, the lower end of the intermediate valve stem 923 extends radially outward to form a platform 924. The upper surface of the platform abuts against the transverse surface of the stepped surface. The outer edge of the platform has the aforementioned protruding end 925, which can slide along the first pressing stop engagement feature on the inner wall of the second pressing stop housing, thereby realizing the corresponding pressing and rotating movements.
[0125] In this example, a fixing member 961, such as a metal sheet, is fixedly installed on the lower surface of the table. The upper and lower ends of the elastic component 96 are fixedly installed on the bottom inner side of the fixing member and the pressing stop base, respectively. The fixing member is roughly a ring-shaped structure, or it can be an arc-shaped structure, etc. The lower surface of the ring-shaped structure can have a groove that cooperates with the elastic component, etc.
[0126] Main reference Figure 9 In one possible implementation, taking the fixed member as a roughly annular structure as an example, optionally, a first limiting structure 971 can be provided or formed on the radially outer side of the annular structure, such as a protrusion. Correspondingly, a second limiting structure 972, such as a strip groove, is provided on the inner wall of the second pressing stop housing. In this way, the elastic component is compressed as the protrusion slides in the strip groove. Through the cooperation of the first / second limiting structures, the frictional force of the pressing stop valve rod during rotation is reduced, and the wear of the pressing stop valve rod and the elastic component is reduced. Obviously, the fixed member can also be an arc-shaped structure with an open side in the circumferential direction, and the first limiting structure can include one, two, or more (e.g., it can be provided at the end of the arc-shaped structure, the outer edge of the arc-shaped structure, etc.).
[0127] Furthermore, traditional pressure stop assemblies are typically injection molded parts, making them susceptible to damage under conditions such as forceful rotation. Therefore, this application utilizes a metal material to ensure the reliability of the pressure stop assembly.
[0128] Main reference Figures 10 to 12 In one possible implementation, when the operating end is in the initial position, the upper surface of the platform of the downward stop valve rod abuts against the transverse surface of the stepped surface at the top of the second downward stop housing, and the protruding end on the downward stop valve rod is disposed within the axial portion of the first downward stop mating feature, thereby ensuring the reliability of the initial state and avoiding phenomena such as misoperation. Figure 10When the pressure stop valve rod is pressed down, it will overcome the elastic force of the elastic component and move downward. When the moving distance is greater than the height of the axial portion, the side wall of the axial portion will no longer be under the lateral constraint of the pressure stop valve rod. The pressure stop valve rod will then enter the circumferential portion of the first pressure stop fitting feature and can rotate along the circumferential portion under the action of rotational force. Figure 11 When the downward pressure stop valve rod rotates to the end position of the circumferential part under the action of rotational force, the protruding end of the downward pressure stop valve rod abuts against the side wall of the second downward pressure stop housing, and the downward pressure stop valve rod can no longer rotate, thus ensuring the reliability of the operating end and thus ensuring the safety of the stove. Figure 12 ).
[0129] As can be seen, in the preferred embodiment of the application, the cooperation between the protruding end and the first / second downward pressure stop features allows the user to accurately perceive the current operating status, improving the user's operating experience. The mechanical locking mechanism based on the first / second downward pressure stop features ensures the reliability of the rotation / up / down stop function, thus avoiding safety hazards caused by misoperation, structural failure, etc.
[0130] Based on the above structure, this application also provides a method for controlling a stove, which is mainly used to control the stove by applying external force to the operating terminal in a manual or automatic manner, and to adjust the operating parameters such as the firepower when the stove is on.
[0131] Main reference Figure 13 And further refer to Figures 10 to 12 In one possible implementation, the control method mainly includes the following steps:
[0132] S1310. Apply a pressing force to the operating end, thereby causing the protruding end to move downward along the axial direction.
[0133] S1320 When the protruding end enters the circumferential portion via the axial portion, a rotational external force is applied to the operating end, thereby causing the protruding end to move along the circumferential portion.
[0134] Based on a pre-established mapping relationship between the rotation angle and the proportional valve assembly of the stove, the operating parameters of the stove, such as the firepower, can be adjusted by rotating the operating end.
[0135] S1330. When the stove is overflowing or about to overflow and the current firepower of the stove is less than or equal to the preset firepower, the stove is set to operate at the lowest firepower setting.
[0136] In this way, by operating the stove at its lowest heat setting, cooking interruptions due to stove shutdown can be effectively avoided. Specifically, when the stove is operating at its lowest heat setting, the intake valve of the proportional valve assembly is open, and the exhaust valve is closed. A very small amount of gas reaches the burner through the connecting structure, which is expected to effectively suppress / eliminate the current overflowing situation without causing the burner to extinguish, thus ensuring the sustainability of the cooking process. Because cooking interruptions due to stove shutdown are avoided, the continuity of the entire cooking process is guaranteed.
[0137] It is understandable that those skilled in the art can determine the form of the cooking state, the specific detection method, and its correspondence with the lowest heat setting based on actual needs. For example, the overflow state can be determined by the parameters of the stove itself, the detection components configured on the stove, and the detection components configured on other equipment related to the stove. For instance, the overflow state of the pot can be determined by whether the heat is extinguished or by image data.
[0138] Furthermore, it is understood that those skilled in the art can determine the specific methods for judging the overflow state and the types it includes based on actual needs. For example, the overflow state can include two states: impending overflow and already overflowed. Both the impending overflow and already overflowed states can further include multiple levels. Taking the already overflowed state as an example, it can include, but is not limited to, several states such as slightly stable, slightly rising, rapid overflow, and severe overflow. The overflow state of the pot can be determined by an image detection component installed above the cooktop (such as an image acquisition component installed on a range hood).
[0139] In this embodiment, the preset heat level is the lowest heat level among conventional heat levels. If the current heat level of the stove is higher than the preset heat level, the heat level should be reduced first. If the overflowing situation cannot be suppressed / eliminated after reducing the heat level to the preset heat level, the stove should be operated at the lowest heat level constructed based on the interconnected structure. If the current heat level is already the lowest heat level among conventional heat levels, the overflowing situation can be suppressed / eliminated without turning off the stove by directly operating it at the lowest heat level constructed based on the interconnected structure. Since the cross-sectional size of the interconnected structure is much smaller than the cross-sectional size of the second gas outlet, the heat level of the burner generated based on the interconnected structure can be called the lowest heat level of the burner.
[0140] In other words, when the current heat of the stove is greater than the preset heat, adjusting the current heat should begin with lowering the heat. While adjusting the heat, the overflow status of the pot should be continuously determined based on the image data of the pot. If the overflow is effectively suppressed at a certain heat level (greater than the preset heat), then that heat level can be maintained, or the heat can be appropriately increased. If the overflow is completely eliminated, the heat can be increased. If the overflow is still not effectively suppressed even when the heat is lowered to the lowest heat level (the preset heat), then the stove needs to be operated at the lowest heat level constructed based on the interconnected structure.
[0141] In this embodiment, the specific operation mode of the minimum firepower setting is as follows: the intake valve of the main on / off valve and the corresponding proportional valve assembly of the burner are opened, and the first and second outlet valves of the proportional valve assembly are closed. In this way, based on the connection structure, the inner ring of the burner still has a certain firepower when the first and second outlet valves of the proportional valve assembly corresponding to it are closed.
[0142] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effect of this application, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously or in other orders, and some steps can be added, replaced or omitted.
[0143] It should be noted that although the control method for home appliances constructed in the above specific manner has been described as an example, those skilled in the art will understand that this application is not limited thereto. In fact, users can flexibly adjust the relevant steps and parameters in the steps according to actual application scenarios and other circumstances.
[0144] The technical solutions of this application have 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 scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, 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 scope of protection of this application.
