Description

Technical Field

[0001] This utility model belongs to the field of gas stove technology, specifically, it relates to 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] The process of installing the cooktop base under the countertop involves first assembling various cooktop components onto the base, then the installer lifts the base and places it under the countertop. Generally, there are two common installation methods for the cooktop base under the countertop: The first is to directly fix the base to the underside of the countertop using a fixing component. This method is very cumbersome and can easily damage the countertop. Furthermore, because the base itself obstructs the installation, the connection is unstable, and the base is prone to detachment; this method is now obsolete. The second method is to suspend the cooktop base under the countertop using a connecting bracket. Common hanging methods include: first fixing the connecting bracket under the countertop, then lifting the cooktop base and connecting it to the bracket; or first fixing the connecting bracket to the cooktop base, with the installer simultaneously lifting both the cooktop base and the connecting bracket, then suspending the connecting bracket on the countertop; or having a split connecting bracket structure, with one part fixed to the countertop and the other part fixed to the cooktop base, then lifting the cooktop base to connect the components of the connecting bracket.

[0004] However, the above installation methods are all quite cumbersome, and the connecting brackets need to be fixed to the tabletop, which damages the tabletop and reduces its strength.

[0005] Therefore, the applicant improved the above installation method. Chinese Patent Application No. CN202323210764.7 discloses a cooktop without a cooktop surface. This cooktop includes a cooktop basin with an upward opening that is suspended below the countertop. The cooktop basin has a horizontal base. A heat spreader is fixed to the lower surface of the countertop. The lower surface of the heat spreader has a protruding surface and a downwardly extending connector. This connector is connected to the base of the cooktop basin, thereby suspending and fixing the cooktop basin below the countertop.

[0006] The patent discloses two installation methods. The first method requires fixing the connector to the heat spreader first, 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 lifted while being fixed 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; secondly, using the control valve to further clamp and fix the heat spreader under the countertop; thirdly, connecting the fixing piece to the cooktop and placing the cooktop under the countertop; and fourthly, rotating the positioning piece on top of 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] Although the two installation methods mentioned above do not damage the countertop, the actual installation process is complicated and tedious, especially in the step of fixing and bonding the heat spreader to the countertop. The requirements are quite strict, and once the heat spreader is fixed, it is difficult to remove easily, making the operation extremely inconvenient. This creates hidden dangers for later maintenance and causes many troubles.

[0009] In view of the above, this utility model is hereby proposed. Utility Model Content

[0010] 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 cooktop without cooktops to simplify the installation process.

[0011] The second 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.

[0012] The third objective of this utility model is to provide a cooktop without a cooktop surface. This structure utilizes the deformation of the connecting bracket to shrink inward, thereby passing through the mounting hole on the countertop, and then opening outward to support it on the countertop, thus suspending the bottom shell of the cooktop under the countertop in one go and stably.

[0013] The fourth objective of this utility model is to provide a cooktop without a cooktop surface, which can reduce the distance between the connecting bracket 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.

[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 stove without a cooktop, comprising:

[0016] The cooktop base is the main body that supports the cooktop components and is used for installation under the countertop;

[0017] An adjustable panel is located above the bottom shell of the stove, which can be adjusted vertically.

[0018] An adjustment component, connected to an adjustable panel, is used to adjust the distance between the adjustable panel and the tabletop, with the adjustable panel resting against the lower surface of the tabletop.

[0019] This invention utilizes the adjustable panel's height, allowing for flexible adjustment of the panel's height based on the actual installation environment and usage requirements. This enables the cooktop without a cooktop to easily accommodate installation needs on countertops of varying thicknesses, effectively enhancing the overall stability and reliability of the cooktop.

[0020] A further solution is to install the adjustment component below the adjustable panel and connect it to the bottom shell of the stove, so as to provide at least the force for the adjustable panel to move upward.

[0021] Preferably, the adjusting component is at least partially telescopically mounted on the bottom shell of the stove, or it is rotatably mounted on the bottom shell of the stove, driving the adjustable panel to move up and down;

[0022] Preferably, the adjusting component is at least partially disposed on the outer side of the cooktop bottom shell;

[0023] Preferably, the adjustment component is at least partially located below the bottom shell of the cooktop.

[0024] This invention allows for stable raising and lowering of the adjustable panel simply by operating the adjustment component, making installation easier and more convenient. The up-and-down extension or rotation of the adjustment component drives the adjustable panel's up-and-down movement, resulting in a more precise and stable adjustment process and effectively improving installation efficiency.

[0025] A further option is that the adjustment components include,

[0026] Support frame, connected to adjustable panel;

[0027] 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.

[0028] 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.

[0029] A further design includes a support frame comprising a side wall and a bottom wall. The side wall extends upward and connects to an adjustable panel, while the bottom wall connects to the bottom shell of the cooktop via an adjusting rod. The vertical distance between the bottom wall and the bottom shell of the cooktop is adjustable.

[0030] Preferably, the adjustable panel has a downwardly protruding connecting part, which is connected to the side wall of the support frame;

[0031] 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.

[0032] Preferably, the adjusting rod is a screw rod, which is threadedly connected to the support frame or the bottom shell of the stove, and the vertical distance between the support frame and the bottom shell of the stove is adjusted by the screw drive.

[0033] This invention utilizes the screw transmission principle of the adjusting rod to precisely adjust the vertical distance between the support frame and the bottom shell of the stove, thereby ensuring that the adjustable panel can stably and effectively support the countertop from below, improving the overall stability and reliability of the stove without a cooktop. Furthermore, the threaded connection has self-locking properties, ensuring that the height remains stable after adjustment and preventing changes in the height of the adjustable panel due to vibration or other factors, further enhancing the stability and safety of the stove without a cooktop.

[0034] A further embodiment of this invention is a cooktop-less stove, comprising:

[0035] The connecting bracket has one end connected to the bottom shell of the stove, and the other end is used to support the bottom shell of the stove on the countertop and suspend it below the countertop.

[0036] Preferably, the connecting bracket includes,

[0037] Annular connector;

[0038] The lower end of the suspension bracket is fixedly connected to the ring connector, and the upper end is used to support it on the table.

[0039] The upper end of the fixed bracket is fixedly connected to the annular connector, and the lower end is fixedly connected to the bottom shell of the stove.

[0040] Preferably, there are at least two suspension brackets and two fixing brackets, which are alternately distributed along the circumferential interval of the annular connector.

[0041] This utility model of a cooktop-less stove can suspend the cooktop's bottom shell under the countertop in one go using a connecting bracket. The combined effect of the connecting bracket supporting the cooktop above the countertop and the adjustable panel abutting against the countertop below the countertop securely clamps the countertop between the support arm and the clamping components, effectively solving the problem of the cooktop's bottom shell falling off the countertop due to shaking, and greatly improving the stability and reliability of the cooktop-less stove after installation.

[0042] This utility model's connecting bracket utilizes a ring-shaped connector as its core component, providing a stable structural foundation for the entire bracket and ensuring a tight and reliable connection between all parts, thus enhancing the overall load-bearing capacity. The upper end of the hanging bracket passes underneath the adjustable panel and countertop, providing stable support, while the lower end is firmly fixed to the ring-shaped connector. This structure makes stove installation more convenient and efficient, while maintaining stable support during use. Combined with the adjustable panel's abutment against the countertop, it effectively prevents the stove from shaking or shifting, greatly improving safety and stability. The upper end of the fixing bracket is tightly fixed to the ring-shaped connector, and the lower end is firmly connected to the stove's bottom shell, further strengthening the overall structural stability of the stove and ensuring that the relative positions of the stove's components remain stable under various usage conditions, thereby improving the stove's reliability.

[0043] A further option is that the suspension frame includes

[0044] The lower end of the connecting arm is fixedly connected to the annular connector.

[0045] The support arm extends horizontally from the upper end of the connecting arm in a direction away from the central axis of the annular connector;

[0046] Preferably, it also includes a guide arm that extends obliquely upward from the extension end of the support arm toward the central axis of the annular connector.

[0047] The inclined guide arm can convert the reaction force of the suspension frame into a force on the central axis of the annular connector when it abuts against the edge of the mounting hole on the lower surface of the platform. This causes the upper end of the suspension frame to move closer to the central axis of the annular connector and enter the mounting hole of the platform. After passing through the mounting hole, the reaction force of the platform on the guide arm disappears, and the guide arm returns to its original position away from the central axis of the annular connector, so that the support arm can be supported on the platform around the mounting hole.

[0048] Preferably, the connecting arm, support arm, and guide arm are integrally molded. The integral molding process used for the suspension frame helps improve the overall structural strength and stability of the support structure.

[0049] Furthermore, the suspension bracket, fixing bracket, and ring connector are integrally molded structures;

[0050] Preferably, the suspension bracket, the fixing bracket, and the annular connector are integral sheet metal structures made of spring steel.

[0051] From a manufacturing perspective, the hanging bracket, fixing bracket, and ring connector adopt a one-piece molding structure, especially the sheet metal structure formed by cutting and bending spring steel in one piece, which has significant advantages. This design enhances the overall strength and stability, reduces the number of parts, and improves production efficiency. At the same time, the use of spring steel utilizes its own elasticity to reduce assembly difficulty and ensure the reliability and safety of the stove base shell during installation.

[0052] A further embodiment of this invention is that the cooktop-less stove includes a knob mounting assembly, which comprises:

[0053] A knob mounting sleeve, at least partially used for support above the countertop;

[0054] A knob bracket, at least partially used for fixed connection to the bottom shell of the cooktop, located under the countertop;

[0055] The knob mounting sleeve and knob bracket are detachably connected.

[0056] Furthermore, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0057] 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;

[0058] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0059] 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.

[0060] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0061] 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.

[0062] In addition, the adjustment component moves 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. It is conducive to quickly adjusting to the appropriate position during installation and cooperating with the connecting bracket of the hanging stove bottom shell to clamp the countertop, thus improving installation efficiency.

[0063] This utility model, through the connecting bracket, can suspend the bottom shell of the stove, which supports the burner head and other stove components, under the countertop in a one-time and stable manner, greatly simplifying the installation steps, improving installation efficiency and convenience, and effectively reducing the labor and time costs in the installation process.

[0064] This utility model's connecting bracket utilizes its own structural characteristics to allow the suspension bracket to retract towards the central axis of the annular connector to extend into the tabletop mounting hole, and to open outwards to support the outer periphery of the tabletop mounting hole. This ensures a stable and reliable installation of the stove's bottom shell, effectively solving the problem of potential detachment due to shaking and guaranteeing safe use.

[0065] 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.

[0066] 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

[0080] 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.

[0081] 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.

[0082] 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.

[0083] like Figures 1 to 3 As shown, the cooktop-less cooktop of this utility model includes a cooktop base shell 3 that can be installed under the countertop 4. The cooktop base shell 3 is used to support the burner head 2 and many other components. A connecting bracket 1 is used to install the cooktop base shell 3 under the countertop 4 (see reference). Figure 10 ).

[0084] Specifically, the lower end of the connecting bracket 1 is connected to the bottom shell 3 of the stove, and the upper end passes through the mounting hole 41 on the countertop from bottom to top, supporting the bottom shell 3 of the stove on the countertop 4 and suspending it below the countertop (see...). Figure 3 and Figure 10 This feature greatly simplifies the installation process, improves installation efficiency, and reduces potential safety hazards and installation quality problems caused by improper human operation, making the installation of cooktop-less cooktops more convenient, efficient, and reliable.

[0085] like Figure 6 and Figure 7 As shown, the connecting bracket 1 of this utility model presents a complete integrated connecting structure, including annular connector 13, suspension bracket 12, and fixing bracket 11. There are at least two suspension brackets 12 and four fixing brackets 11 in this design, arranged alternately around the outer periphery of the annular connector 13. The lower end of the fixing bracket 11 is fixedly connected to the bottom shell 3 of the stove, and the upper end is fixedly connected to the annular connector 13. The lower end of the suspension bracket 12 is fixedly connected to the annular connector 3, and the upper end is used to support the bracket on the countertop 4 as it passes through the mounting hole 41 from below the countertop 4 (see reference). Figure 10 ).

[0086] This utility model's connecting bracket utilizes a ring-shaped connector as its core component, providing a stable structural foundation for the entire bracket and ensuring a tight and reliable connection between all parts, thus enhancing the overall load-bearing capacity. The upper end of the hanging bracket passes underneath the adjustable panel and countertop, providing stable support, while the lower end is firmly fixed to the ring-shaped connector. This structure makes the installation of the stove more convenient and efficient, while maintaining stable support during use. The upper end of the fixing bracket is tightly fixed to the ring-shaped connector, and the lower end is firmly connected to the bottom shell of the stove, further strengthening the overall structural stability of the stove and ensuring that the relative positions of the stove's components remain stable under various usage conditions, thereby improving the stove's reliability.

[0087] Among them, such as Figure 6 As shown, the suspension frame 12 includes a connecting arm 121 and a support arm 122. The lower end of the connecting arm 121 is fixedly connected to the annular connector 13, and the upper end extends horizontally away from the central axis of the annular connector 13 to form the support arm 122. The angle α between the support arm 122 and the connecting arm 121 can also be designed to be 80°-105°, preferably 90°-95°. This design angle allows the support arm 122 to provide a stable support effect.

[0088] Preferably, the suspension bracket 12 further includes a guide arm 123, which extends obliquely upward from the extension end of the support arm 122 toward the central axis of the annular connector 13. For example... Figure 10 As shown, the inclined guide arm 123 can convert the reaction force of the suspension frame 12 into a force of the suspension frame 12 toward the central axis of the annular connector 13 when the suspension frame 12 abuts against the edge of the table mounting hole 41 on the lower surface of the table surface 4. This causes the upper end of the suspension frame 12 to move closer to the central axis of the annular connector 13 and enter the table mounting hole 41. After passing through the table mounting hole 41, the reaction force of the table surface 4 on the guide arm 123 disappears, and the guide arm 123 returns to its original position away from the central axis of the annular connector 13, so that the support arm 122 can be supported on the outer peripheral table surface of the table mounting hole 41.

[0089] Furthermore, the connecting arm 121, support arm 122, and guide arm 123 are integrally molded structures. The integral molding process used for the suspension frame 12 helps to improve the overall structural strength and stability of the support.

[0090] The mounting bracket 11 includes a fixing section 111 located at its lower end, which is used for fixed connection with the cooktop base shell 3. The fixing section 111 and the connection part of the cooktop base shell 3 are adapted to each other, preferably by screw connection, such as... Figure 6As shown, the fixing section 111 is provided with screw mounting holes 113 for screw connection. The fixing bracket 11 also includes a connecting section 112, the lower end of which is connected to the fixing section 111, and the other end extends upward to connect with the annular connector 13, thereby forming an integral structure.

[0091] Similarly, the included angle β formed between the fixed section 111 and the connecting section 112 is also set to 70°-110°, preferably 80°-100°, even more preferably 85°-95°, and best at 90°. This angle design allows the fixed section 111 to form a stable mechanical structure with the connecting section 112 after being connected to the bottom shell 3 of the stove. When bearing the weight of the suspended bottom shell of the stove, the force can be evenly transmitted to the entire connecting arm through the reasonable angle configuration, reducing the situation of excessive local stress, enhancing the overall stability and reliability of the connecting arm, and ensuring that the stove remains stable under various usage conditions.

[0092] A further proposed solution is that the fixing frame 11, the suspension frame 12, and the annular connector 13 are integrally formed.

[0093] Preferably, the fixing frame 11, the suspension frame 12 and the annular connector 13 are sheet metal structures integrally bent from spring steel.

[0094] From a manufacturing perspective, the hanging bracket, fixing bracket, and ring connector adopt a one-piece molded structure, especially the sheet metal structure formed by one-piece bending of spring steel, which has significant advantages. This design enhances overall strength and stability, reduces the number of parts, and improves production efficiency. At the same time, the use of spring steel utilizes its own elasticity to reduce assembly difficulty and ensure the reliability and safety of the stove base shell during installation.

[0095] like Figure 3 and Figure 7 As shown, the structure of the stove base shell 3 of this utility model generally includes a base 31 for supporting components such as the burner head 2 and a peripheral wall 32 extending upward from the base 31. The base 31 has concave and convex shapes machined on it to enhance its strength. The peripheral wall 32 is provided with a ventilation structure, which is generally designed as ventilation holes 33 or by dividing the peripheral wall into sections, utilizing the gaps between the sections for ventilation. The embodiment of this utility model uses an inwardly protruding shape stamped on the base 31 of the stove base shell to fix the burner head 2 (see...). Figure 7 The cooktop base 3 also 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. Thus, the fixing section 111 of the fixing bracket 11 is provided with screw mounting holes 113 (see...). Figure 6If 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. In the preferred embodiment of this utility model, the fixing bracket 11 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 provided on the bottom shell of the stove, or it can be installed on the bottom shell of the stove through an adapter. In the preferred embodiment of this utility model, the assembly part 30 is provided on the base 31 of the bottom shell of the stove.

[0096] Regarding the specific structure and installation form of the assembly part 30, it can also be placed on a fixed frame, and then the fixed frame is fixed to the chassis 31 of the stove bottom shell (not shown in the figure), ensuring 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 both mounted on the same fixed frame. This integrated installation strategy significantly improves the compactness and synergy of the structure, making the connection between components tighter and the cooperation more seamless, effectively reducing potential risks such as structural loosening or unstable connections that may occur due to the dispersed installation of components. More preferably, the number of fixed frames corresponds precisely to the number of burners 2, and each fixed frame is firmly supported on the chassis 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 weight on the stove bottom shell, and provides a solid structural guarantee for the long-term stable operation of the entire stove.

[0097] like Figures 3 to 5 As shown, the cooktop-less stove of this utility model includes,

[0098] The adjustable panel 61, located above the cooktop base 3, features unique vertical adjustability. The adjustable panel 61 has mounting holes 611 for the support arm 12 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.

[0099] Adjustment component 62, which is connected to adjustable panel 61, is used to adjust the distance between adjustable panel 61 and tabletop 4, and to abut adjustable panel 61 against the lower surface of tabletop 4.

[0100] The purpose of the above structure is to work closely with the support arm 122 in the connecting bracket 1 to clamp the countertop 4 between the support arm 122 and the adjustable panel 61, thereby improving the stability of the stove bottom shell 3 suspended under the countertop.

[0101] This invention cleverly utilizes the key feature of its adjustable panel, 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, cooktop-less cooktops can easily achieve adaptability thanks to the adjustable panel. 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 adjustable panel, forming a stable integrated 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.

[0102] Further solutions include, for example Figure 4 and Figure 5 As shown, the adjusting component 62 mainly includes:

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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 connecting parts. 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.

[0110] 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.

[0111] like Figure 3 and Figure 8 As shown, the cooktop-less stove of this utility model includes a knob mounting assembly 7, which mainly includes:

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by a threaded connection.

[0120] 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.

[0121] 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.

[0122] Furthermore, such as Figure 4 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.

[0123] like Figure 9 As shown, the method for installing the cooktop-less stove of this invention on a countertop mainly includes the following steps:

[0124] S1. Install the connected adjustable panel 61 and adjustment component 62 onto the bottom shell 3 of the stove.

[0125] Before or after step S1, install the internal components of the stove, such as the burner head 2, knob bracket 72, and switch valve 8, along with the connecting bracket 1, onto the stove base shell 3. Ensure that the distance between the adjustable panel 61 and the support arm 122 is significantly greater than the thickness of the countertop 4. Preferably, the adjustable panel is lowered to its extreme position. This pre-assembly of the stove's internal structure facilitates subsequent overall installation and avoids inconvenience or interference caused by missing or improperly installed internal components during the later installation process.

[0126] S2. Lift the cooktop base 3 under the countertop 4. The guide arm 123 at the upper end of the suspension bracket 12 of the connecting bracket 1 abuts against the lower end of the mounting hole 41 on the countertop. The inclined guide arm 123 converts the reaction force of the abutment into a force that causes the suspension bracket 12 to move towards the central axis of the annular connector 13. This causes the support arm 122 to pass through the mounting hole 41 from below the countertop 4. After the support arm 122 passes through the mounting hole 41, the reaction force of the countertop on the support arm 122 and guide arm 123 disappears, and the support arm 122 returns to its original position, thus supporting the cooktop base 3 on the outer periphery of the mounting hole 41, suspending the cooktop base 3 under the countertop 4 (see...). Figure 10 ).

[0127] This step involves carefully lifting the cooktop base 3, ensuring its stability to prevent damage or installation difficulties caused by shaking or tilting. During this process, the installer must carefully control the force and angle to ensure the support arm is accurately aligned with the mounting holes on the countertop.

[0128] S3. Operate the adjustment component 62 to adjust the height of the adjustable panel 61 upwards, so that it abuts against the lower surface of the countertop 4. Through the cooperation of the support arm 122, the bottom shell 3 of the stove is initially fixed. This step can further enhance the stability of the stove bottom shell installation, reduce the possibility of shaking, and ensure the firmness and safety of the entire stove without a cooktop after installation, laying a good foundation for subsequent fine-tuning and use.

[0129] 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 1 and Figure 2 ).
