Description

Technical Field

[0001] This utility model belongs to the field of gas stove technology, specifically, it relates to a connecting frame for a stove without a cooktop and a stove without a cooktop. Background Technology

[0002] Cooktops are indispensable kitchen appliances in daily family life. As people's living standards continue to improve, the appearance of the kitchen has gradually become more important, and simple and elegant minimalist decoration has become popular. This has led to the emergence of cooktops without cooktops. The overall structure of the cooktop is set under the countertop of the cabinet, with only openings on the countertop for the burners and control valve to pass through. Thus, in terms of appearance, only two burners and control valves are visible on the countertop, making the overall appearance of the countertop simple and meeting the user's visual needs.

[0003] However, cooktop-less cooktops have a drawback: insufficient load-bearing capacity. The cooktop base, which supports the cooktop and other components, is suspended below the countertop. Specifically, the upper edge of the outer perimeter of the cooktop base has a horizontally extending flange, which is connected to the countertop via connectors. Because the main components are concentrated in the central area of ​​the cooktop base, the center of gravity is far from the connectors. This not only increases the torque but also widens the angle between the line connecting the center of gravity and the connectors and the vertical direction. This means that the connectors must bear not only the vertical weight but also the load... The horizontal tension makes the connectors prone to horizontal deformation, which can cause them to detach from the countertop or even cause the entire cooktop base to fall off. This not only affects the user experience but also poses a safety hazard. In addition, the unsupported base of the cooktop can deform downwards after prolonged use, causing the burner to shift position. In severe cases, this can lead to burner breakage and natural gas leaks, seriously endangering the user's life and causing users to hesitate when purchasing cooktops.

[0004] The applicant has improved the installation structure of a cooktop without a cooktop. Chinese Patent Application No. CN202323210764.7 discloses a cooktop without a cooktop, which includes a cooktop basin with an upward-facing opening suspended below a kitchen countertop. The cooktop basin has a horizontal base. A heat spreader is fixed to the lower surface of the countertop, and a connecting piece with a protruding surface extending downwards is provided on the lower surface of the heat spreader. This connecting piece connects to the base of the cooktop basin, thereby suspending and fixing the cooktop basin below the countertop.

[0005] The patent discloses two installation structures. Although these two installation structures solve the problem of preventing the stove basin from deforming and falling off, they are still relatively troublesome to install.

[0006] The first installation method requires first fixing the connector to the heat spreader, then gluing the heat spreader to the underside of the countertop, and finally fixing the cooktop to the connector from under the countertop. During installation, the cooktop needs to be supported while being secured to the connector, which is not only time-consuming and prone to installation accidents, but also requires a high level of skill to secure the heat spreader.

[0007] The second installation method involves first attaching the heat spreader to the corresponding position on the lower surface of the countertop; then, using a control valve, further clamping and securing the heat spreader under the countertop; third, connecting the fixing piece to the cooktop and placing the cooktop under the countertop; and fourth, rotating the positioning piece above the countertop to connect it with the fixing piece. This method also requires lifting the cooktop while rotating the positioning piece to connect it to the fixing piece. Since the connection point is under the countertop, positioning is more complicated, and the installation process also requires considerable physical effort and time.

[0008] In view of the above, this utility model is hereby proposed. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology. The primary objective is to solve the cumbersome and complicated problems in the installation process of cooktops without cooktops, and to provide a connecting frame for cooktops without cooktops, so as to simplify the installation steps and suspend the bottom shell of the cooktop under the countertop in one go.

[0010] The second objective of this utility model is to provide a connecting bracket for a cooktop without a cooktop. This structure can smoothly pass through the mounting hole on the countertop by rotating the second bracket closer to the first bracket to reduce its volume. Then, the second bracket is rotated in the opposite direction to open it up and support it on the countertop.

[0011] The third objective of this utility model is to provide a stove without a cooktop that uses the aforementioned connecting frame.

[0012] The fourth objective of this utility model is to provide a cooktop without a cooktop surface, which can reduce the distance between the connecting frame and the center of gravity of the cooktop bottom shell, thereby effectively preventing the cooktop bottom shell from falling off the countertop due to load-bearing deformation.

[0013] The fifth objective of this utility model is to provide a cooktop without a cooktop surface, which has the characteristics of adapting to cooktops of different thicknesses and achieving stable fixation.

[0014] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0015] A connecting frame for a cooktop-less stove is used to suspend the bottom shell of the cooktop below the countertop. The connecting frame includes...

[0016] The first bracket is used to connect to the bottom shell of the stove;

[0017] The second bracket, hinged to the first bracket, has a support arm that can pass through a mounting hole in the tabletop from below, for support on the tabletop.

[0018] This utility model utilizes a connecting frame to stably suspend the cooktop base, which supports the burner head and other cooktop components, from under the countertop in a single operation. The first support of the connecting frame primarily serves to securely connect to the cooktop base, laying the foundation for subsequent suspension. The second support is hinged to the first support, providing it with a degree of freedom of movement. This freedom allows the support arm on the second support to smoothly pass through the mounting holes on the countertop from below, thus providing effective support and ensuring the stability and reliability of the entire cooktop connecting frame.

[0019] A further proposed solution is that the second stent has at least two states relative to the first stent, including:

[0020] In the first state, the support arm of the second bracket is close to the first bracket and can extend into the mounting hole of the tabletop from below the tabletop.

[0021] In the second state, the support arm of the second bracket is away from the first bracket and is used to support the outer periphery of the mounting hole on the table.

[0022] In the first state, the second bracket's support arm moves closer to the first bracket due to the rotation of the second bracket, leaving an appropriate distance between its outer periphery and the table mounting hole, allowing the support arm to smoothly extend into the table mounting hole from below the table, thus providing the possibility for subsequent installation of the support arm through the table mounting hole.

[0023] In the second state, the support arm of the second bracket passes through the mounting hole on the countertop. As the second bracket is reversed, it moves away from the first bracket and is able to support the outer periphery of the mounting hole on the countertop. In this way, the connecting frame of the entire cooktop without a cooktop provides reliable support and stability, ensuring that the cooktop remains stable during use and does not shake or shift.

[0024] A further embodiment is that the connecting frame includes an elastic element for providing an elastic force for the second support to switch from the first state to the second state;

[0025] Preferably, the elastic element is a torsion spring structure. In the first state, one end of the torsion spring abuts against the side of the first support opposite to the second support, and the other end of the torsion spring abuts against the side of the second support close to the first support.

[0026] The above structure makes the process of switching the second support from the first state to the second state smoother and more convenient, reducing problems such as jamming or wear that may be caused by switching due to rigid mechanical structure.

[0027] A further embodiment is that the second bracket includes a connecting arm, which is connected to the support arm and has an included angle between them. The connecting arm is pivotally connected to the first bracket, and the two cooperate to suspend the bottom shell of the stove under the countertop after the support arm passes through the mounting hole.

[0028] Preferably, the connecting arm and the supporting arm form an angle α, where α is 70°-110°, more preferably α is 75°-105°, and even more preferably α is 85°-95°.

[0029] Preferably, the connecting arm extends vertically, and the support arm is connected to the upper end of the connecting arm;

[0030] Preferably, a shaft hole for mounting a pivot is provided at a certain distance from the upper end of the connecting arm, and the distance between the shaft hole and the upper end of the connecting arm is less than the distance between the shaft hole and the lower end of the connecting arm;

[0031] Preferably, the second bracket is a sheet metal part that is integrally bent to form a support arm and a connecting arm;

[0032] The sheet metal parts forming the connecting arm are cut, bent, and rolled into shaft holes on both sides. A clearance groove is punched on the connecting arm between the two shaft holes to avoid the pivot located between the two shaft holes.

[0033] The second bracket of this utility model rotates relative to the first bracket, so that the connecting arm can not only pass through the table mounting hole, but also rotate in the opposite direction to drive the support arm to support the outer periphery of the table mounting hole. The structural design of the second bracket is more reasonable and stable, improving the overall connection performance and assembly effect.

[0034] The first support includes,

[0035] A fixed arm, located at the lower end, is used for fixed connection with the bottom shell of the stove.

[0036] The articulated arm has one end connected to the fixed arm and the other end extending upwards and hinged to the second bracket. The second bracket can rotate within a certain range around the hinged end of the articulated arm.

[0037] Preferably, an angle β is formed between the fixed arm and the hinged arm, where β is 70°-110°, more preferably β is 75°-105°, and even more preferably β is 85°-95°.

[0038] Preferably, the first bracket is a sheet metal part that is integrally bent to form a fixed arm and a hinged arm;

[0039] Preferably, the top end of the hinge arm is cut, bent, and rolled into a shaft hole.

[0040] The first bracket of this utility model is hinged to the second bracket at the upper end of the hinge arm, so that the second bracket can rotate within a specific range around the hinge end of the hinge arm, thereby realizing the switching of different states of the second bracket and meeting various installation and use requirements.

[0041] In terms of structural optimization, a specific angle β is formed between the fixed arm and the hinged arm. The value of this angle β ranges from 75° to 105°, with 85° to 95° being more preferred, and the most ideal value being β of 90°. This angle range can provide a relatively balanced performance in terms of mechanical transmission, structural compactness, and rational spatial layout.

[0042] From a manufacturing perspective, the first bracket uses a sheet metal integral bending process to form the fixed arm and the hinge arm. This integral molding process helps to improve the overall structural strength and stability of the bracket. Furthermore, the top of the hinge arm is processed through cutting, bending, and rolling to form a shaft hole, which is used for hinged engagement with the second bracket, ensuring a reliable connection and flexible rotation between the two, effectively improving the assembly accuracy and durability of the entire connecting frame.

[0043] The first and second supports of this utility model are preferably formed by integral bending of elastic spring steel sheet metal parts. When the support arm of the second support extends into the table mounting hole, it generates a certain deformation by utilizing its own elasticity, so that the support arm can pass through the table mounting hole more smoothly.

[0044] This utility model provides a cooktop without a cooktop surface, including a cooktop bottom shell, the cooktop bottom shell being provided with an assembly part for installing the aforementioned connecting bracket.

[0045] A further proposed solution is to have at least two assembly parts on the bottom shell of the stove;

[0046] Preferably, at least two assembly parts are grouped together and distributed around the outer periphery of the same burner on the bottom shell of the stove. More preferably, at least two assembly parts around the outer periphery of the same burner are evenly distributed in the same circumferential direction.

[0047] Alternatively, the two assembly parts are installed on one side of the two burners, roughly in line with the center of the two burners.

[0048] Preferably, the assembly part is located on the fixed frame, and the fixed frame is fixedly connected to the bottom shell of the stove.

[0049] Preferably, the burner head and the corresponding assembly located on its outer side are mounted on the same mounting bracket.

[0050] More preferably, the number of mounting brackets corresponds one-to-one with the number of burners.

[0051] A further embodiment of this invention is that the cooktop-less cooktop includes a clamping assembly, which is disposed below the cooktop and cooperates with the support arm to clamp the cooktop between the support arm and the clamping assembly.

[0052] Preferably, the clamping assembly includes,

[0053] An adjustable panel is set above the bottom shell of the stove in an adjustable manner. The adjustable panel has adjustable panel mounting holes for the support arm and burner head to pass through from bottom to top.

[0054] An adjustment component, connected to an adjustable panel, is used to adjust the distance between the adjustable panel and the support arm, thereby clamping the tabletop between the support arm and the adjustable panel.

[0055] This invention utilizes the adjustable panel in the clamping assembly, which allows the cooktop-less cooktop to easily accommodate various countertop thicknesses. Furthermore, it works in conjunction with the support arm to securely clamp the countertop between the support arm and the clamping assembly, effectively solving the problem of the cooktop falling off the countertop due to shaking of the cooktop's bottom shell. This significantly improves the stability and reliability of the cooktop-less cooktop after installation.

[0056] Furthermore, the adjustment components include,

[0057] Support frame, connected to adjustable panel;

[0058] The adjustment rod is used to install the support frame on the bottom shell of the stove. By adjusting the relative height between the support frame and the bottom shell of the stove, the adjustable panel can be moved up and down.

[0059] Preferably, the support frame includes a side wall and a bottom wall, the side wall extends upward and connects to the adjustable panel, and the bottom wall is connected to the bottom shell of the stove through an adjusting rod, and the vertical distance between the bottom wall and the bottom shell of the stove is adjustable;

[0060] Preferably, the support frame is set outside the bottom shell of the stove, the side wall is located on the side of the bottom shell of the stove, the bottom wall is located below the bottom shell of the stove, and one end of the adjusting rod passes through the bottom wall and connects to the bottom shell of the stove.

[0061] Preferably, the adjusting rod includes a screw rod, which is threadedly connected to the support frame or the bottom shell of the stove, and adjusts the vertical distance between the support frame and the bottom shell of the stove through screw transmission.

[0062] This invention utilizes an adjusting rod to change the relative height between the support frame and the bottom shell of the stove, thereby enabling the adjustable panel to move up and down. This structural design allows the entire adjusting component to flexibly and precisely control the position of the adjustable panel to adapt to different installation needs and usage scenarios.

[0063] Furthermore, the vertical distance between the support frame and the bottom shell of the stove is precisely adjusted by utilizing the screw transmission principle of the adjusting rod, thereby ensuring that the clamping component can stably and effectively perform its clamping function on the countertop, and improving the stability and reliability of the overall structure of the stove without a cooktop.

[0064] A further embodiment of this invention is that the cooktop-less stove includes a knob mounting assembly, which comprises:

[0065] A knob mounting sleeve, at least partially used for support above the countertop;

[0066] A knob bracket, at least partially used for fixed connection to the bottom shell of the cooktop, located under the countertop;

[0067] The knob mounting sleeve and knob bracket are detachably connected;

[0068] Preferably, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0069] Preferably, the knob mounting sleeve is connected to the knob bracket at a position above the tabletop and / or inside the knob mounting hole on the tabletop and / or below the tabletop;

[0070] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0071] This utility model utilizes a knob mounting component to further enhance the stability of the cooktop's bottom shell when fixedly installed under the countertop. By flexibly adjusting the vertical relative distance between the knob mounting sleeve and the knob bracket, the component can adapt to countertops of different thicknesses, further improving the versatility and adaptability of cooktops without cooktop surfaces in various installation environments.

[0072] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0073] This utility model uses a connecting frame to suspend the bottom shell of the stove, which supports the burner head and other stove components, under the countertop in a single, stable manner. This greatly simplifies the installation process, improves installation efficiency and convenience, and effectively reduces labor and time costs during installation.

[0074] The connecting bracket adopts a hinged design and state switching between the second bracket and the first bracket: the support arm is close to the first bracket to extend into the mounting hole on the countertop, and away from the first bracket to support the outer periphery of the mounting hole on the countertop, so that the installation of the bottom shell of the stove is stable and reliable, effectively solving the problem of falling off due to shaking and ensuring safety in use.

[0075] This utility model of a cooktop-less appliance features an adjustable panel with height adjustable up and down, which can adapt to countertops of different thicknesses. This effectively enhances the applicability and compatibility of the appliance in various kitchen countertop environments, making it widely applicable to various kitchen decoration and configuration needs. It eliminates the need for additional adjustments or adaptations due to differences in countertop thickness, reducing installation limitations caused by differences in countertop thickness specifications and greatly improving the practicality and convenience of the product.

[0076] In addition, the adjustment components of the clamping assembly move the adjustable panel through the cooperation of the support frame and the adjustment rod. The structure is reasonably designed and the adjustment process is relatively simple, which is conducive to quickly adjusting to the appropriate position to clamp the tabletop during installation, thus improving installation efficiency.

[0077] In the knob mounting assembly of the cooktop without a cooktop, the variety of connection positions between the knob mounting sleeve and the knob bracket, as well as the adjustable distance between them, can adapt to different countertop thicknesses and knob models, improving the flexibility and versatility of knob installation and facilitating precise assembly in various product design and usage scenarios.

[0078] The preferred threaded connection between the knob mounting sleeve and the knob bracket ensures a secure connection between them while effectively preventing loosening or displacement caused by frequent knob rotation. This maintains the stability of the knob during operation and provides users with a consistently reliable operating experience.

Detailed Implementation

[0092] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0093] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0094] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0095] like Figure 1 and Figure 2 As shown, the connecting frame 1 of this utility model for a cooktop-less stove is used to suspend the cooktop base 3, which carries the burner head 2 and other components, securely and in one go below the countertop 4 (see reference). Figure 9 and Figure 10 This design eliminates the need for installers to simultaneously lift the cooktop base 3 and connect the connecting bracket 1 to the cooktop base 3, or to simultaneously lift the cooktop base 3 and connect the various components of the connecting bracket 1 – all complex and inconvenient actions. This feature greatly simplifies the installation process, improves efficiency, and reduces potential safety hazards and installation quality issues caused by improper human operation, making the installation of cooktop-less cooktops more convenient, efficient, and reliable.

[0096] The connecting frame 1 of this utility model presents a complete integrated connecting structure, including a first bracket 11 and a second bracket 12. The first bracket 11 is used to connect with the bottom shell 3 of the stove. The second bracket 12 includes a support arm 121, which is used to support the countertop 4 by passing through the countertop mounting hole 41 from below the countertop 4. The first bracket 11 and the second bracket 12 are hinged. The second bracket 12 can rotate within a predetermined angle range relative to the first bracket 11, so that the support arm 121 can pass through the countertop mounting hole 41. Then, by rotating in the opposite direction, it is stably supported on the countertop 4 on the outer periphery of the countertop mounting hole 41, thereby achieving the purpose of suspending the bottom shell 3 of the stove under the countertop 4.

[0097] The second bracket 12 presents at least two different states relative to the first bracket 11: The first state is where the support arm 121 of the second bracket 12 moves closer to the first bracket 11 due to its own rotation, creating favorable conditions for the support arm 121 to smoothly enter the countertop mounting hole 41 from under the countertop 4, thus providing a practical possibility for the subsequent installation of the support arm 121 through the countertop mounting hole 41. The second state is where, after the support arm 121 passes through the countertop mounting hole 41, the second bracket 12 rotates in the opposite direction, causing the support arm 121 to move away from the first bracket 11 and be stably supported on the countertop surface around the countertop mounting hole 41. This ingenious design provides solid and reliable support and stability for the entire cooktop without a cooktop, effectively ensuring that the cooktop remains stable during use and preventing shaking or displacement.

[0098] In a further embodiment, the connecting frame 1 includes an elastic element 13, the main function of which is to provide the necessary elastic force for the second support to change from the first state to the second state.

[0099] In the preferred design, the elastic element 13 adopts a torsion spring structure. When the second support 12 is in the first state, the first torsion arm 131 of the torsion spring abuts against the side of the first support 11 facing away from the second support 12, while the second torsion arm 132 of the torsion spring abuts against the side of the second support 12 close to the first support 11.

[0100] The above design enables the torsion spring to assist the second bracket 12 in smoothly transitioning from the first state where the support arm 121 approaches the first bracket 11 and extends into the tabletop mounting hole 41, to the second state where the support arm 121 moves away from the first bracket 11 and is supported on the outer periphery of the tabletop mounting hole 41, based on its elastic characteristics during the state switching process. This further optimizes the working performance of the connecting bracket, improves the stability and reliability of the cooktop installation structure without a cooktop, and to a certain extent makes the operation process smoother and more convenient, reducing problems such as jamming or wear that may be caused by rigid mechanical structure switching.

[0101] In another embodiment, the connecting frame 1 of this utility model can also omit the design of the elastic element 13, and the second bracket 12 can be manually operated by the installer to rotate in the opposite direction relative to the first bracket 11.

[0102] The first bracket 11 has a fixed arm 111 at its lower end. The fixed arm 111 is used to establish a stable fixed connection with the bottom shell 3 of the stove. The fixed arm 111 is preferably adapted to the connection part of the bottom shell 3 of the stove. The first bracket 11 also includes a hinge arm 112, one end of which is connected to the fixed arm 111, and the other end extends upward and is hinged to the second bracket 12. This allows the second bracket 12 to rotate flexibly within a certain angle range around the hinge end of the hinge arm 112, thereby achieving switching between different states to meet various needs in the installation and use process.

[0103] Furthermore, a β angle is formed between the fixed arm 111 and the hinge arm 112. This angle ranges from 70° to 110°, preferably from 75° to 105°, and more preferably from 85° to 95°. This angle range design relatively reduces the distance between the hinge end and the cooktop bottom shell. Combined with the spatial layout of the cooktop components within the cooktop bottom shell, it exhibits a relatively balanced and excellent performance in terms of mechanical transmission path planning, overall structural compactness, and rational spatial layout.

[0104] The first bracket 11 uses a sheet metal integral bending process to shape the fixed arm 111 and the hinge arm 112. This integral molding process significantly improves the overall structural strength and stability of the bracket. Furthermore, the top of the hinge arm 112 undergoes a series of fine processes such as cutting, bending, and rolling to form a shaft hole (not shown in the figure) for mounting the pivot 14. The main purpose of this shaft hole is to ensure precise hinge engagement with the second bracket, thereby ensuring a high degree of reliability and rotational flexibility in the connection between the two. This effectively improves the precision level of the entire connecting frame during assembly and its durability during use.

[0105] The second bracket 12 includes a connecting arm 122, which is connected to the support arm 121 at a specific angle, such that when the support arm 121 is supported on the countertop 4, the connecting arm 122 passes downward through the countertop mounting hole 41. The connecting arm 122 is connected to the first bracket 11 via a pivot connection, and the two work together to stably suspend the cooktop base 3 below the countertop 4 after the support arm 121 passes smoothly through the countertop mounting hole 41.

[0106] An angle α is formed between the connecting arm 122 and the support arm 121. The value of the angle α is between 70° and 110°, preferably between 75° and 105°, and more preferably between 85° and 95°. The best design is that the angle α is less than 90°. When the second bracket 12 is in the second state, the support arm 121 is supported on the table 4, while the connecting arm 122 can abut against the wall of the mounting hole 41 on the table, thereby enhancing the lateral support effect.

[0107] The connecting arm 122 extends vertically, and the support arm 121 is connected to the upper end of the connecting arm 122. It is located on the side of the connecting arm 122 facing away from the first bracket. A shaft hole 123 for mounting the pivot 14 is provided at a certain distance from the upper end of the connecting arm 122. The distance L1 between the shaft hole 123 and the upper end of the connecting arm 122 is less than the distance L2 between the shaft hole 123 and the lower end of the connecting arm 122.

[0108] In a preferred embodiment, the second bracket 12 is a sheet metal part formed by an integral bending process to create a support arm 121 and a connecting arm 122. The two sides of the sheet metal part forming the connecting arm 122 are processed by cutting, bending, and rolling to form shaft holes 123. Two shaft holes 123 are formed on both sides of the sheet metal part. A clearance groove 124 is stamped on the connecting arm 122 between the corresponding two shaft holes 123 to allow clearance from the portion of the pivot 14 located between the two shaft holes (see reference). Figure 2 ).

[0109] To increase the support strength of the support arm 121 and prevent its deformation, the end of the support arm 121 away from the connecting arm 122 is turned upward to form a reinforcing rib 125; an anti-slip structure, such as an anti-slip pad or anti-slip coating, is provided on the side surface of the support arm 121 used to support the table to prevent the support arm from slipping on the table and enhance lateral stability.

[0110] The innovative rotating design of the second bracket relative to the first bracket allows the connecting arm to not only pass precisely through the tabletop mounting hole, but also to drive the support arm to be stably supported on the outer periphery of the tabletop mounting hole during reverse rotation. As a result, the structural design of the second bracket is significantly improved in terms of rationality and stability, thereby effectively enhancing the overall connection performance and assembly effect. The avoidance groove design of the connecting arm makes the hinge structure of the second bracket and the first bracket more compact, further reducing the resistance caused by the excessive lateral dimension of the second bracket when passing through the tabletop mounting hole.

[0111] In the preferred embodiment, the first bracket 11 and the second bracket 12 of this utility model are preferably made of spring steel sheet metal with elastic properties and formed by an integral bending process. In this way, when the support arm of the second bracket is inserted into the table mounting hole, it can generate appropriate deformation due to its own elasticity, which greatly facilitates the support arm to pass through the table mounting hole more smoothly.

[0112] like Figure 3 and Figure 7 As shown, the cooktop-less stove of this utility model includes a cooktop base shell 3. The structure of the cooktop base shell 3 generally includes a base plate 31 for supporting components such as the burner head 2 and a peripheral wall 32 extending upward from the base plate 31. The base plate 31 is machined with concave and convex shapes to enhance its strength. The peripheral wall 32 is provided with a ventilation structure, which is generally designed as a ventilation hole 33 or the peripheral wall is designed in sections, utilizing the gap between the two sections for ventilation. The cooktop base shell 3 has an assembly part 30. The main function of the assembly part 30 is to install the aforementioned connecting bracket 1. The structure and connection method of the assembly part 30 are not limited. If screws are used for fixing, the assembly part 30 can be the screw holes on the cooktop base shell. Thus, the fixing arm 111 of the first bracket 11 is provided with screw mounting holes 113 (see reference). Figure 1 If a plug-in connection is used, the assembly part can be a plug hole on the bottom shell of the stove. There are many connection methods, which will not be listed here. Preferably, the connecting bracket 1 and the bottom shell of the stove are fastened together with screws, and the assembly part 30 is a screw hole. In addition, the assembly part 30 can be directly or indirectly provided on the bottom shell of the stove. That is, the assembly part can be directly set on the bottom shell of the stove, or it can be installed on the bottom shell of the stove through an adapter. The details will be described in detail later.

[0113] To reduce the number of holes drilled on the countertop 4, the countertop mounting hole 41 serves as the burner mounting hole for the stove. Alternatively, it could be the knob mounting hole 42 on the countertop, but the burner mounting hole is preferred. Of course, additional perforations can be made on the countertop, requiring a decorative cover to cover the support arm 121 supported on the countertop. Similarly, for the burner mounting hole, a burner decorative cover or a drip tray 5 is needed to cover the support arm 121 (see [reference]). Figure 10 and 11 ).

[0114] Further design considerations for the assembly parts 30 include their number and location on the cooktop base 3. The number of assembly parts 30 is related to factors such as the size, weight, shape of the cooktop base 3, and the number of burners 2. To achieve a stable installation, the cooktop base 3 is provided with at least two assembly parts 30. In a highly advantageous layout, at least two assembly parts 30 are combined into a group and rationally distributed around the outer periphery of a specific burner 2 on the cooktop base 3, especially for single-burner cooktops or multi-burner designs with a central burner. Of course, for multi-burner cooktops, assembly parts can be placed around each burner, or around two burners that serve a balancing function on the cooktop. More ingeniously, these assembly parts surrounding the outer periphery of the same burner are evenly distributed in the same circumferential direction. A preferred embodiment of this invention is to provide two assembly parts 30 around each burner 2, with the assembly parts 30 symmetrically distributed on both sides of the burner 2. This evenly distributed design is not accidental. It can achieve an ideal balanced force distribution effect in terms of mechanical structure, effectively avoiding structural stability problems that may be caused by uneven local force distribution. At the same time, it also achieves optimized configuration in terms of spatial layout, making the internal structure of the entire stove more compact and reasonable.

[0115] Another feasible assembly layout (not shown in the figure) allows for cost savings in multi-burner cooktops, provided the connecting brackets meet predetermined strength requirements. This reduces the number of connecting brackets, requiring only one assembly on each of the two burners. The assembly corresponds one-to-one with each burner, and the two assembly sections are roughly aligned with the center of the two burners, either between or outside the burners. However, to ensure lateral stability, strict installation requirements are placed on the connecting brackets' angles, particularly the extension direction of the support arms. The support arms of the two connecting brackets extend in opposite directions. Specifically, if the two assembly sections are between the burners, their extension directions are opposite; if they are outside the burners, their extension directions are opposite. This layout demonstrates unique adaptability and practicality under specific cooktop design concepts and kitchen space planning needs, further optimizing the overall space utilization and operational convenience of the cooktop while meeting basic installation requirements.

[0116] Regarding the specific structure and installation form of the assembly part 30, it is preferable to place the assembly part 30 on the fixing frame 34, and the fixing frame 34 is fixedly connected to the stove bottom shell 3 to ensure high stability and reliability under various usage environments and operating conditions. Further optimized design shows that the burner 2 and the corresponding assembly part 30 located on its outer side are jointly installed on the same fixing frame 34. This integrated installation strategy significantly improves the compactness and coordination of the structure, making the connection between components tighter and the cooperation more seamless, effectively reducing potential risks such as structural loosening or unstable connection that may occur due to the dispersed installation of components. More preferably, the number of fixing frames 34 corresponds precisely to the number of burners 2, and each fixing frame 34 is firmly supported on the base 31 of the stove bottom shell, thereby constructing a stable and orderly internal support frame. At the same time, it enhances the strength of the stove bottom shell, ensures a balanced distribution of the weight on the stove bottom shell, and provides a solid structural guarantee for the long-term stable operation of the entire stove.

[0117] Further solutions include, for example Figure 4 , Figure 5 and Figure 7 As shown, the cooktop without a cooktop of this utility model includes a clamping component 6, which is set below the cooktop 4. Its design purpose is to work closely with the support arm 121 in the connecting frame 1 to clamp the cooktop 4 between the support arm 121 and the clamping component 6, thereby improving the stability of the cooktop bottom shell 3 suspended below the cooktop.

[0118] Clamping assembly 6 mainly includes the following components:

[0119] The adjustable panel 61, located above the cooktop base 3, features unique vertical adjustability and includes mounting holes 611 for the support arm 121 and burner head 2 to pass smoothly upwards. This design allows the adjustable panel 61 to flexibly adjust its height according to different installation needs and usage scenarios, thus adapting to the installation requirements of countertops of various thicknesses and greatly expanding the application range and adaptability of cooktops without cooktop surfaces.

[0120] Adjustment component 62, which is connected to adjustable panel 61, is used to adjust the distance between adjustable panel 61 and support arm 121, and to clamp table 4 between support arm 121 and adjustable panel 61.

[0121] This invention cleverly utilizes the key feature of the adjustable panel in the clamping assembly, which allows for vertical adjustment, to significantly improve the performance of cooktop-less cooktops from two core dimensions. Firstly, when faced with a wide variety of countertops of varying thicknesses on the market, the adjustable panel allows for easy and adaptable installation. Whether the countertop is ultra-thin or ultra-thick, a simple adjustment allows the cooktop to perfectly integrate with the countertop, greatly improving the product's versatility and adaptability in different kitchen environments and effectively reducing installation limitations and inconveniences caused by differences in countertop thickness. Secondly, through a close working mechanism with the support arm, the countertop is securely clamped between the support arm and the clamping assembly, forming a stable overall structure. This stable clamping structure fundamentally and effectively solves the potential risk of the cooktop falling off the countertop due to wobbling of the cooktop's base. During daily use, neither slight vibrations during cooking nor accidental collisions in the kitchen environment will easily damage the connection stability between the cooktop and the countertop. This greatly improves the overall stability and reliability of the cooktop after installation, providing users with a safer, more durable, and worry-free user experience.

[0122] Further solutions include, for example Figure 5 As shown, the adjusting component 62 mainly includes:

[0123] The support frame 621 is connected to the adjustable panel 61; preferably, both have pin holes 620 and 610, which are fixedly connected by pins at the installation site, or the support frame and the adjustable panel are fixedly connected by other assembly methods such as screws. The support frame 621 extends along one side of the stove bottom shell 3. Preferably, there are two support frames 621, which are correspondingly arranged on the left and right sides of the stove bottom shell 3.

[0124] The adjusting rod 622 is used to install the support frame 621 on the bottom shell 3 of the stove. By adjusting the relative height between the support frame 621 and the chassis 31 of the bottom shell of the stove, the adjustable panel 61 is moved up and down.

[0125] The support frame 621 includes a side wall 6211 and a bottom wall 6212. The side wall 6211 extends upward and connects to the adjustable panel 61, while the bottom wall 6212 is connected to the base 31 of the cooktop shell 3 via an adjusting rod 622, and the vertical distance between the bottom wall 6212 and the base 31 of the cooktop shell is flexibly adjustable. Preferably, the support frame 621 is an integral structural component formed by bending a sheet metal part to create the side wall 6211 and bottom wall 6212, thereby improving its support strength.

[0126] To ensure convenient and stable connection between the adjustable panel 61 and the support frame 621, a downwardly protruding connecting part 612 is provided on the lower surface of the adjustable panel 61. The connecting part 612 is preferably an integral structural component formed by bending both ends of the adjustable panel 61 downwards. This integral molding design not only reduces the number of parts and assembly complexity but also enhances the strength and stability of the connection, effectively avoiding potential safety hazards and performance degradation caused by loose connections or component separation.

[0127] Considering the space utilization and packaging convenience of the adjustable panel 61 and the support frame 621 during transportation, the adjustable panel 61 and the support frame 621 are designed as two independent modules. At the installation site, they can be easily assembled, typically using pins or bolts as the connection method. Pin holes 610, 620 or bolt mounting holes are correspondingly provided on the connecting part 612 of the adjustable panel and the side wall 6211 of the support frame.

[0128] Ventilation design is crucial for ensuring combustion efficiency in cooktops. To avoid affecting ventilation inside and outside the cooktop, a vent 6120 is designed at the connection part 612 of the adjustable panel 61, and / or a vent 6210 is designed on the side wall 6211 of the support frame 621, to cooperate with the ventilation holes 33 on the peripheral wall 32 of the cooktop bottom shell, forming a through ventilation channel. This ventilation channel can effectively exhaust combustion exhaust gases, introduce fresh air, maintain the internal pressure balance and suitable temperature environment of the cooktop, thereby improving the overall performance stability and reliability of the cooktop and extending the product's service life.

[0129] Regarding the connection structure design between the support frame 621 and the cooktop base 3, a matching pre-assembly structure is provided between them to facilitate a convenient and quick assembly process. Specifically, an upwardly extending claw 6213 is provided on the bottom wall 6212 of the support frame 621, while a corresponding claw through hole (not shown in the figure) is provided on the base 31 of the cooktop base. The claw 6213 is preferably a spring-loaded structure, with its upper end bent towards the side wall 6211, and the distance between the upper end of the claw 6213 and the side wall 6211 is smaller than the distance between its lower end and the side wall 6211. When connecting the support frame and the cooktop base, the claw of the support frame is first aligned and passed through the claw through hole of the cooktop base. Since the claw has a certain elastic deformation capability, it will undergo moderate elastic deformation during the process of passing through the claw through hole. After the claw passes through the claw through hole, it can reopen by its own elastic restoring force, thereby forming a stable pre-assembly structure. This pre-assembly method eliminates the need for complex tools or additional connectors. The clever combination of claws and perforations allows for quick initial positioning and connection, significantly improving assembly efficiency. After pre-assembly, an adjusting rod is used to connect the support frame to the cooktop base. Because the claws pass through the cooktop base, this pre-assembly design does not affect the adjusting rod's ability to adjust the relative height between the support frame and the cooktop base, further ensuring the stability and reliability of the entire connection structure.

[0130] Regarding the selection of the type of adjusting rod 622, a screw, a component with high-precision adjustment characteristics, is preferred. This screw is tightly fitted to the support frame or the cooktop base via a threaded connection. Utilizing the mature and precise transmission principle of helical drive, it enables precise fine-tuning of the vertical distance between the support frame and the cooktop base. Through this structural design, the entire adjusting component can adjust the position of the adjustable panel in real time with a highly flexible and precise control strategy, effectively adapting to different installation requirements and diverse usage scenarios, providing a solid technical guarantee for the stable operation of cooktops without cooktop surfaces in various countertop environments.

[0131] Further solutions include, for example Figure 6 and Figure 7 As shown, the cooktop-less stove of this utility model includes a knob mounting assembly 7, which mainly includes:

[0132] The knob mounting sleeve 71 has at least a portion that plays a crucial supporting role above the tabletop 4. The knob mounting sleeve 71 has a through hole 710 that runs vertically through the inside for mounting the knob shaft and / or mounting the valve stem 81 of the switch valve 8.

[0133] The knob bracket 72, at least a portion of which is set under the countertop and fixedly connected to the bottom shell 3 of the stove, thereby constructing a reliable basic support frame for the entire knob mounting assembly; the knob mounting sleeve 71 and the knob bracket 72 are detachably connected.

[0134] The knob mounting sleeve 71 is height-adjustable relative to the knob bracket 72. In other words, the vertical distance between the upper end of the knob mounting sleeve 71 and the knob bracket 72 is adjustable. This adjustable distance allows the component to flexibly adapt to countertops of different thicknesses, further expanding the versatility and adaptability of cooktops without cooktops in various installation environments. Whether the countertop is ultra-thin or thick, a simple adjustment operation can perfectly match the knob mounting component to the countertop, ensuring that the knob maintains good operating feel and ease of use regardless of countertop height.

[0135] In addition, the knob mounting sleeve 71 can be partially supported above the tabletop 4 and is detachably connected to the knob bracket 72 below the tabletop 4. The vertical distance is adjustable, which allows the knob mounting assembly to also have the function of clamping the tabletop.

[0136] The connection position between the knob mounting sleeve 71 and the knob bracket 72 has several options. It can be located above the tabletop 4 and / or inside the knob mounting hole 42 on the tabletop and / or below the tabletop 4. If the knob mounting sleeve 71 is entirely above the tabletop 4, the upper end of the knob bracket 72 passes through the knob mounting hole 42 on the tabletop from below and connects to the knob mounting sleeve 71. If the knob bracket 72 is entirely below the tabletop 4, the lower end of the knob mounting sleeve 71 passes through the knob mounting hole 42 on the tabletop from above and connects to the knob bracket 72. If the lower end of the knob mounting sleeve 71 passes through the knob mounting hole 42 on the tabletop from above and the upper end of the knob bracket 72 passes through the knob mounting hole 42 on the tabletop from below and the lower end of the knob mounting sleeve 71 and the upper end of the knob bracket 72 are connected within the knob mounting hole 42 on the tabletop. The above installation positions are just examples and are not all limited. They can be combined according to the actual structure of the knob mounting sleeve and the knob bracket.

[0137] This multi-position selectable connection method has significant advantages in practical applications. It can be flexibly adjusted according to different kitchen decoration styles, countertop designs and user habits, further improving the adaptability and user satisfaction of cooktops without cooktops in various usage scenarios.

[0138] A further embodiment is that the knob mounting sleeve 71 includes a cylindrical connector 711 and a support ring 712 disposed on the outer periphery of the connector 711. The lower end of the connector 711 is connected to the knob bracket 72. The support ring 712 is used to support the surface 4. The support ring 712 is annular and is sleeved on the outer periphery of the connector 711. Preferably, the inner ring is provided with an internal thread and is threadedly connected to the connector 711, or it is an integral structure with the connector 711.

[0139] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by a threaded connection.

[0140] Preferably, the knob bracket 72 includes a mounting bracket 721 fixedly connected to the cooktop base 3 and a connecting sleeve 722 protruding upwards on the mounting bracket 721. The connecting sleeve 722 is used to extend into the knob mounting hole 42 on the countertop and connect with the connector 711 of the knob mounting sleeve 71. The outer diameter of the connecting sleeve 722 preferably matches the knob mounting hole 42 on the countertop. The connecting sleeve 722 has an internal thread, and the lower end of the connector 711 of the knob mounting sleeve 71 has an external thread that can match the connecting sleeve 722. During installation, tightening the threaded connection will achieve the connection and fixation between the cooktop base 3 and the countertop 4 at the knob. More preferably, the connecting sleeve 722 is fixed to the mounting bracket 721 by screws or pins, or the connecting sleeve 722 and the mounting bracket 721 are an integral structure.

[0141] Threaded connections offer significant advantages such as stable connection, precise adjustment, and convenience. This invention utilizes an innovative knob mounting component design to further enhance the stability of the cooktop's base when fixed under the countertop. By flexibly adjusting the relative vertical distance between the knob mounting sleeve and the knob bracket, and with multiple selectable connection positions and the robust characteristics of the threaded connection, this component perfectly adapts to countertops of varying thicknesses and design styles. This comprehensively improves the versatility and adaptability of cooktops without cooktop surfaces in various complex installation environments, providing users with a more convenient, safe, and stable user experience.

[0142] Furthermore, such as Figure 7 As shown, the adjustable panel 61 is provided with an adjustable panel knob mounting hole 613. The connecting sleeve 722 of the knob bracket 72 passes through the adjustable panel knob mounting hole 613, extends into the knob mounting hole 42 of the table surface 4, and connects with the connector 711 of the knob mounting sleeve 71.

[0143] like Figure 8 As shown, the method for installing the cooktop-less stove of this invention on a countertop mainly includes the following steps:

[0144] S1. Connect the first bracket 11 of the connecting frame 1 to the assembly part 30 of the stove bottom shell 3;

[0145] First, the first bracket 11 must be precisely and securely connected to the assembly part 30 of the cooktop base. This step requires installers to strictly follow the design requirements and installation specifications to ensure a tight and seamless connection between the first bracket and the assembly part, without any looseness or deviation, thus laying a solid foundation for subsequent installation operations. For example, during the connection process, the fit of the connection parts must be carefully checked, appropriate tools and connectors must be used, and the operation must be carried out according to the specified torque or connection method to ensure the reliability and stability of the connection.

[0146] Before or after step S1, install the internal components of the stove, such as the clamping assembly 6, burner head 2, knob bracket 72, and switch valve 8, onto the stove base shell 3. Ensure that the distance between the adjustable panel and the support arm is much greater than the thickness of the countertop, preferably by adjusting the adjustable panel to its extreme position. This pre-assembly of the internal structure of the stove facilitates subsequent overall installation and avoids inconvenience or interference caused by missing or improperly installed internal components during the later installation process.

[0147] S2. Lift up the bottom shell 3 of the stove and rotate the second bracket 12 of the connecting frame so that the support arm 121 passes through the mounting hole 41 of the countertop from below the countertop 4.

[0148] Carefully lift the cooktop base 3 in this step, taking care to keep it stable to avoid damage or installation difficulties caused by shaking or tilting. Figure 9 As shown, following the design structure where the second bracket 12 rotates relative to the first bracket 11, the second bracket 12 is rotated so that the support arm 121 equipped with the second bracket 12 can smoothly and accurately pass through the mounting hole 41 on the tabletop 4 from below to above. During the rotation, the installer needs to control the force and angle of rotation to ensure that the support arm can be accurately aligned with the mounting hole on the tabletop.

[0149] During the process of pushing the support arm 121 of the second bracket 12 from bottom to top into the table mounting hole 41, the wall of the table mounting hole 41 will first apply an abutting force to the extension end of the support arm 121. This force will cause the upper end of the connecting arm 122 of the second bracket to overcome the torsion spring force and rotate towards the first bracket 11. At this time, the lower end of the connecting arm 122 will move away from the first bracket 11. During the process of the support arm 121 moving upward after entering the table mounting hole 41, the extension end of the support arm 121 and the connecting arm 122 may simultaneously abut against the wall of the table mounting hole 41 and deform. Since the second bracket 12 is formed by bending a sheet metal part, it has a certain elastic deformation, which can further ensure that the support arm 121 passes through the table mounting hole 41 during installation.

[0150] S3. Rotate the second bracket 12 in the opposite direction. The support arm 121 supports the outer periphery of the mounting hole 41 on the countertop, and suspend the bottom shell 3 of the stove under the countertop 4.

[0151] When the support arm 121 passes through the tabletop mounting hole 41, the force exerted by the hole wall on the support arm 121 disappears. The upper end of the second bracket 12 will return to its initial state due to the torsion spring force and rotate in the opposite direction away from the first bracket 11. At this time, the support arm 121 is supported on the outer periphery of the tabletop mounting hole 41, realizing the hoisting of the stove base shell 3 (see...). Figure 9 ).

[0152] After step S3, adjust the clamping assembly 6 and raise the height of the adjustable panel 61 so that it fits against the lower surface of the countertop 4. Through its cooperation with the support arm 121, the cooktop base 3 is initially fixed. This step further enhances the stability of the cooktop base installation, reduces the possibility of shaking, and ensures the firmness and safety of the entire cooktop without a cooktop surface after installation, laying a good foundation for subsequent fine-tuning and use.

[0153] Then, install the knob mounting sleeve 71 on the countertop 4, connect the knob mounting sleeve 71 to the knob bracket 72, install the knob 82, and fix the liquid tray 5 to the burner head 2, preferably by screw locking; then install the ignition cover 21 and the pot bracket 9 to complete the installation of the cooktop-less stove on the countertop (see...). Figure 10 and Figure 11 ).

[0154] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
