Description

Technical Field

[0001] The invention belongs to the technical field of gas stoves, and in particular relates to a stove without a stovetop and an installation method thereof. Background Art

[0002] Cookers are indispensable kitchen appliances in daily family life. With the continuous improvement of people's living standards, the appearance of the kitchen has gradually received attention, and simple and elegant minimalist decoration has also been widely welcomed by people, which has led to the emergence of stoves without cooktops. The overall structure of the cooker is set under the countertop of the cabinet, and only openings for the burner and the control valve to pass through are opened on the countertop. Therefore, in terms of appearance, only two burners and a control valve can be seen on the countertop, making the overall appearance of the countertop simple and meeting the visual needs of users.

[0003] When installing the stove bottom shell under the countertop, it is necessary to first install many parts of the stove on the stove bottom shell, and then the installer lifts the stove bottom shell and installs the stove bottom shell under the countertop. Generally speaking, there are two common installation methods for installing the stove bottom shell under the countertop: the first is to directly fix the stove bottom shell on the lower surface of the countertop through a fixing component. This installation method is very troublesome and easily damages the countertop. In addition, since the stove bottom shell itself hinders the installation, the connection is unstable and the stove bottom shell is easy to fall off, which has been eliminated; the second method is to use a connecting bracket to hang the stove bottom shell under the countertop. Common hanging methods include first fixing the connecting bracket under the countertop, and then lifting the stove bottom shell to connect it to the connecting bracket; or first fixing the connecting bracket to the stove bottom shell, the installer simultaneously lifting the stove bottom shell and the connecting bracket, and then hanging the connecting bracket on the countertop; or, the connecting bracket is a split connection structure, one part is first fixed to the countertop, and the other part is fixed to the stove bottom shell, and then the stove bottom shell is lifted to connect the parts of the connecting bracket.

[0004] However, the above installation methods are all relatively complicated, and the connecting bracket needs to be fixed on the table top, which causes damage to the table top and reduces the strength of the table top.

[0005] Therefore, the applicant has made improvements to the above installation method. The Chinese patent application number CN202323210764.7 discloses a stove without a stove top, which includes a stove basin with an upward opening and suspended below the cabinet countertop, and the stove basin is provided with a horizontal bottom plate. A heat spreader is fixed on the lower surface of the countertop, and a connector protruding from the lower surface of the heat spreader and extending downward is provided, and the connector is connected to the bottom plate of the stove basin, so that the stove basin is suspended and fixed below the countertop.

[0006] The patent specifically discloses two installation methods. The first installation method requires first fixing the connecting piece to the soaking plate, then gluing the soaking plate to the bottom of the countertop, and then fixing the stove basin to the connecting piece under the countertop. During the installation process, the stove basin needs to be lifted and fixed to the connecting piece at the same time, which is not only time-consuming and prone to installation accidents, but also has high requirements for fixing the soaking plate.

[0007] The second installation method firstly adheres the corresponding position of the heat spreader to the lower surface of the countertop; the second step is to further clamp and fix the heat spreader under the countertop by installing a control valve; the third step is to connect the fixing piece to the stove basin and place the stove basin under the countertop; the fourth step is to rotate the positioning piece above the countertop to connect it with the fixing piece. This installation method also requires that the positioning piece be rotated while lifting the stove basin to position and connect the fixing piece. Since the connection position between the two is under the countertop, positioning is more troublesome, and the installation process also requires more physical strength and time.

[0008] Although the above two installation methods do not cause damage to the countertop, the actual installation process is complicated and tedious, especially in the process of fixing and bonding the heat spreader and the countertop, which is quite demanding. Once the heat spreader is fixed, it is difficult to remove it easily, and the operation is extremely inconvenient, which in turn lays hidden dangers for subsequent maintenance operations and causes many troubles.

[0009] In view of this, the present invention is proposed. Summary of the invention

[0010] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art. The first purpose is to solve the cumbersome and complicated problems existing in the installation process of a stove without a cooktop, and to provide a stove without a cooktop to achieve the effect of simplifying the installation steps.

[0011] A second object of the present invention is to provide a stove without a cooktop, which has the characteristics of adapting to countertops of different thicknesses and achieving stable fixation.

[0012] The third object of the present invention is to provide a stove without a cooktop. The structure utilizes the deformation of the connecting bracket itself to achieve inward contraction, so that it can pass through the countertop installation hole, and then open to the periphery, and then support on the countertop, so that the bottom shell of the stove can be hung under the countertop in a one-time and stable manner.

[0013] A fourth object of the present invention is to provide a stove without a cooktop, which can reduce the distance between the connecting bracket and the center of gravity of the stove bottom shell, thereby effectively preventing the stove bottom shell from falling off the tabletop due to load-bearing deformation.

[0014] A fifth object of the present invention is to provide a method for installing a stove without a cooktop, so as to achieve the effect of stably hanging the bottom shell of the stove under the countertop.

[0015] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0016] A stove without a stove top, comprising:

[0017] The bottom shell of the stove is the main body that carries the stove parts and is used to be installed under the countertop;

[0018] An adjustable panel is arranged above the bottom shell of the cooker in an adjustable manner up and down;

[0019] The adjusting component is connected with the adjustable panel and is used for adjusting the distance between the adjustable panel and the table top so as to make the adjustable panel abut against the lower surface of the table top.

[0020] The present invention makes use of the characteristic that the adjustable panel can be adjusted up and down, and uses the adjusting components to flexibly adjust the height of the adjustable panel according to the actual installation environment and usage requirements, so that the stove without a cooktop can easily meet the installation requirements of various countertops with different thicknesses, effectively enhancing the overall stability and reliability of the stove.

[0021] A further solution is that the adjustment component is installed below the adjustable panel and connected to the bottom shell of the cooker to at least provide a force for the adjustable panel to move upward;

[0022] Preferably, at least part of the adjustment component is telescopically mounted on the bottom shell of the cooker, or rotatably mounted on the bottom shell of the cooker to drive the adjustable panel to move up and down;

[0023] Preferably, the adjustment component is at least partially arranged on the outside of the bottom shell of the cooker;

[0024] Preferably, the adjusting component is at least partially arranged below the bottom shell of the cooker.

[0025] The invention only needs to operate the adjusting component to achieve stable lifting of the adjustable panel when adjusting the height of the adjustable panel, and the installation is easier and more convenient. The adjusting component can be extended or rotated up and down to drive the adjustable panel to move up and down, making the adjustment process more accurate and stable, and effectively improving the efficiency of installation.

[0026] A further solution is that the adjusting component includes:

[0027] a support frame connected to the adjustable panel;

[0028] The adjusting rod is used to install the support frame on the bottom shell of the stove, and the adjustable panel is driven to move up and down by adjusting the relative height between the support frame and the bottom shell of the stove.

[0029] The present invention uses an adjustment rod to change the relative height between the support frame and the bottom shell of the cooker, thereby driving the adjustable panel to move up and down. This structural design enables the entire adjustment component to flexibly and accurately control the position of the adjustable panel to adapt to different installation requirements and usage scenarios.

[0030] A further solution is that the support frame includes a side wall and a bottom wall, the side wall extends upward and is connected to the adjustable panel, the bottom wall is connected to the bottom shell of the stove through an adjustment rod, and the upper and lower distances between the bottom wall and the bottom shell of the stove are adjustable;

[0031] Preferably, the adjustable panel is provided with a connection portion protruding downward, and the connection portion is connected to the side wall of the support frame;

[0032] Preferably, the support frame is arranged outside the stove bottom shell, the side wall is located on the side of the stove bottom shell, the bottom wall is located below the stove bottom shell, and one end of the adjustment rod passes through the bottom wall and is connected to the stove bottom shell;

[0033] Preferably, the adjustment 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 through screw transmission.

[0034] The present invention utilizes the spiral transmission principle of the adjusting rod to accurately adjust the upper and lower distances between the supporting frame and the bottom shell of the stove, so as to ensure that the adjustable panel can stably and effectively play its abutment effect on the table top under the table top, thereby improving the stability and reliability of the overall structure of the stove without a stove top; and the threaded connection has self-locking properties, which can ensure that the height after adjustment remains stable and unchanged, avoiding changes in the height of the adjustable panel due to vibration or other factors, thereby further improving the stability and safety of the stove without a stove top.

[0035] A further solution is that the stove without a cooktop of the present invention comprises:

[0036] A connecting bracket, one end of which is connected to the bottom shell of the cooker, and the other end is used to support the bottom shell of the cooker on the table to hang it below the table;

[0037] Preferably, the connecting bracket comprises:

[0038] Ring connector;

[0039] A hanging frame, the lower end of which is fixedly connected to the annular connecting piece, and the upper end of which is used to be supported on the table surface;

[0040] A fixing frame, the upper end of which is fixedly connected to the annular connecting piece, and the lower end of which is fixedly connected to the bottom shell of the cooker;

[0041] Preferably, there are at least two suspension frames and at least two fixing frames, which are alternately distributed along the circumference of the annular connecting member.

[0042] The stove without a cooktop of the present invention can use the connecting bracket to suspend the bottom shell of the stove under the table top at one time, and utilize the synergistic effect of the support of the connecting bracket above the table top and the abutment of the adjustable panel under the table top to stably clamp the table top between the supporting arm and the clamping assembly, effectively solving the problem of the stove bottom shell falling off the table top due to shaking, and greatly improving the stability and reliability of the stove without a cooktop after installation.

[0043] The connecting bracket of the present invention uses an annular connector as a core component, which provides a stable structural foundation for the entire connecting bracket, ensures that the connection between the various parts is tight and reliable, and enhances the overall bearing capacity. The upper end of the suspension bracket can pass through the adjustable panel and the table top from below and be stably supported on the table top, while the lower end is firmly fixed to the annular connector. This structure makes the installation of the stove more convenient and efficient, and can maintain a stable supporting state during use. The adjustable panel abuts against the table top under the table top, effectively preventing the stove from shaking or displacing, greatly improving the safety and stability of use. The upper end of the fixed bracket is tightly fixed to the annular connector, and the lower end is firmly connected to the bottom shell of the stove, further strengthening the stability of the overall structure of the stove, ensuring that the relative positions between the various components of the stove are stable and unchanged under various conditions of use, thereby improving the reliability of the stove.

[0044] A further solution is that the suspension frame includes

[0045] A connecting arm, the lower end of which is fixedly connected to the annular connecting piece;

[0046] A support arm extends substantially horizontally from the upper end of the connecting arm in a direction away from the central axis of the annular connecting member;

[0047] Preferably, it also includes a guide arm, which extends obliquely upward from the extended end of the support arm toward the direction close to the central axis of the annular connector.

[0048] The inclined guide arm can convert part of the reaction force abutting against the edge of the mounting hole on the lower surface of the table into a force acting in the direction of the center axis of the annular connecting member when the suspension bracket abuts upward. This makes the upper end of the suspension bracket approach the direction of the center axis of the annular connecting member, thereby entering the table mounting hole. After passing through the table mounting hole, the reaction force of the table on the guide arm disappears, and the guide arm resets in the direction away from the center axis of the annular connecting member, so that the support arm can be supported on the table outside the mounting hole.

[0049] Preferably, the connecting arm, the supporting arm and the guiding arm are integrally formed. The use of an integrally formed process for the suspension frame helps to improve the overall structural strength and stability of the bracket.

[0050] Furthermore, the suspension frame, the fixing frame and the annular connecting member are an integrally formed structure;

[0051] Preferably, the suspension bracket, the fixing bracket and the annular connecting member are sheet metal structures integrally formed of spring steel.

[0052] From the manufacturing process point of view, the one-piece structure of the suspension bracket, fixing bracket and annular connector, especially the sheet metal structure formed by cutting and bending spring steel, 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 reduces the difficulty of assembly by utilizing its own elasticity, ensuring the reliability and safety of the stove bottom shell during installation.

[0053] A further solution is that the stove without a cooktop of the present invention includes a knob installation assembly, and the knob installation assembly includes:

[0054] a knob mounting sleeve, at least partially adapted to be supported above a countertop;

[0055] The knob bracket is at least partially arranged under the table and fixedly connected to the bottom shell of the stove;

[0056] The knob mounting sleeve is detachably connected to the knob bracket.

[0057] Furthermore, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0058] Preferably, the position where the knob mounting sleeve is connected to the knob bracket is above the table top and / or in the knob mounting hole of the table top and / or below the table top;

[0059] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0060] The present invention utilizes a knob installation assembly to further improve the stability of the stove bottom shell being fixedly installed under the countertop. By flexibly adjusting the upper and lower relative distances between the knob installation sleeve and the knob bracket, the assembly can be adapted to countertops of different thicknesses, thereby further improving the versatility and adaptability of the stove without a cooktop in a variety of installation environments.

[0061] The present invention also provides a method for installing a stove without a cooktop, comprising the following steps:

[0062] S1. Install the connected adjustable panel and adjustment components on the bottom shell of the cooker;

[0063] S2. Lift the bottom shell of the stove under the countertop and hang the bottom shell of the stove under the countertop;

[0064] S3. Operate the adjustment component to make the adjustable panel contact the lower surface of the table.

[0065] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0066] The cooktopless stove of the present invention adopts an adjustable panel whose height can be adjusted up and down, and can adapt to countertops of different thicknesses, effectively enhancing the applicability and compatibility of the stove in a variety of kitchen countertop environments, and can be widely applied to various kitchen decoration configuration requirements. There is no need for additional adjustment or adaptation operations due to differences in countertop thickness, reducing installation restrictions caused by differences in countertop thickness specifications, and greatly improving the practicality and convenience of the product.

[0067] In addition, the adjustment component drives the movement of the adjustable panel through the cooperation of the support frame and the adjustment rod. The structural design is reasonable 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 table top, thereby improving the installation efficiency.

[0068] The present invention can hang the stove bottom shell carrying stove parts such as the burner in a one-time and stable manner under the tabletop through the connecting bracket, which greatly simplifies the installation steps, improves the installation efficiency and convenience, and effectively reduces the manpower and time costs during the installation process.

[0069] The connecting bracket of the present invention utilizes the characteristics of its own structure to enable the suspension bracket to shrink in the direction of the central axis of the annular connecting piece to extend into the tabletop mounting hole, and to reset and open toward the periphery to support the periphery of the tabletop mounting hole, so that the installation of the stove bottom shell is stable and reliable, effectively solving the problem of falling off due to shaking, and ensuring safe use.

[0070] In the knob installation assembly of the stove without a cooktop of the present invention, the diversity of the connection positions of the knob installation sleeve and the knob bracket and the adjustable distance between the two can adapt to different countertop thicknesses and knob models, improve the flexibility and versatility of the knob installation, and facilitate precise assembly in various product designs and usage demand scenarios.

[0071] The preferred threaded connection method between the knob mounting sleeve and the knob bracket can effectively prevent loosening or displacement caused by frequent rotation of the knob while ensuring a firm connection between the knob mounting sleeve and the knob bracket, thereby maintaining stability during knob operation and providing users with a continuous and reliable operating experience.

[0072] The method for installing a stove without a cooktop of the present invention comprises the following steps: firstly installing the connected adjustable panel and the adjusting component on the bottom shell of the stove; then, the bottom shell of the stove is simply lifted up under the table top, and the upper end of the hanging bracket of the connecting bracket is passed through the installation hole of the table top and supported above the table top, so that the hanging installation of the bottom shell of the stove under the table top can be completed; finally, the adjusting component is operated to make the adjustable panel abut against the lower surface of the table top, so as to achieve the table top clamping in cooperation with the connecting bracket; the operation is simple, the difficulty of installation is reduced, and it is convenient for the installers to quickly master and implement.

[0073] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0086] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0087] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0088] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0089] like Figures 1 to 3As shown, the stove without a cooktop of the present invention includes a stove bottom shell 3 that can be installed under a countertop 4. The stove bottom shell 3 is used to carry many parts such as a burner 2. The stove bottom shell 3 is installed under the countertop 4 using a connecting bracket 1 (see Fig.10 ).

[0090] Specifically, the lower end of the connecting bracket 1 is connected to the stove bottom shell 3, and the upper end passes through the table top mounting hole 41 from bottom to top, and is supported on the table top 4 to hang the stove bottom shell 3 below the table top (see Figure 3 and Fig.10 This feature greatly simplifies the installation process and improves installation efficiency. It also reduces potential safety hazards and installation quality issues that may be caused by improper human operation, making the installation process of stoves without cooktops more convenient, efficient and reliable.

[0091] like Figure 6 and Figure 7 As shown, the connection bracket 1 of the present invention presents a complete integrated connection structure, including an annular connection member 13, a hanging bracket 12 and a fixing bracket 11. There are at least two hanging brackets 12 and fixing brackets 11, respectively. In this solution, four are used, and they are alternately arranged on the outer periphery of the annular connection member 13 along the circumferential direction of the annular connection member 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 connection member 13. The lower end of the hanging bracket 12 is fixedly connected to the annular connection member 3, and the upper end is used to assume the role of supporting the table top 4 from the bottom of the table top 4 through the table top mounting hole 41 (see Fig.10 ).

[0092] The connecting bracket of the present invention uses the annular connector as the core component, which provides a stable structural foundation for the entire connecting bracket, ensures that the connection between the various parts is tight and reliable, and enhances the overall load-bearing capacity. The upper end of the hanging bracket can pass through the adjustable panel and the table top from below and be stably supported on the table top, while the lower end is firmly fixed to the annular connector. This structure makes the installation of the stove more convenient and efficient, and can maintain a stable support state during use. The upper end of the fixed bracket is tightly fixed to the annular connector, and the lower end is firmly connected to the bottom shell of the stove, which further strengthens the stability of the overall structure of the stove and ensures that the relative positions between the various components of the stove are stable and unchanged under various conditions of use, thereby improving the reliability of the stove.

[0093] Among them, Figure 6 As shown, the suspension frame 12 includes a connecting arm 121 and a supporting arm 122. The lower end of the connecting arm 121 is fixedly connected to the annular connecting member 13, and the upper end extends basically horizontally in a direction away from the central axis of the annular connecting member 13 to form the supporting arm 122. The angle α between the supporting arm 122 and the connecting arm 121 can also be designed to be 80°-105°, preferably 90°-95°. This design angle enables the supporting arm 122 to provide a stable supporting effect.

[0094] 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 direction close to the central axis of the annular connecting member 13. Fig.10 As shown, the inclined guide arm 123 can convert part of the reaction force abutting against the edge of the table mounting hole 41 on the lower surface of the table 4 into a force of the hanger 12 toward the center axis of the annular connector 13 when the hanger 12 abuts upward. This makes the upper end of the hanger 12 approach the direction of the center axis of the annular connector 13, thereby entering the table mounting hole 41. After passing through the table mounting hole 41, the reaction force of the table 4 on the guide arm 123 disappears, and the guide arm 123 is reset in the direction away from the center axis of the annular connector 13, so that the support arm 122 can be supported on the outer peripheral table of the table mounting hole 41.

[0095] Furthermore, the connecting arm 121, the supporting arm 122, and the guiding arm 123 are an integrally formed structure. The use of an integrally formed process for the suspension frame 12 helps to improve the overall structural strength and stability of the bracket.

[0096] The fixing bracket 11 includes a fixing section 111 at its lower end, and the fixing section 111 is used to be fixedly connected to the stove bottom shell 3. The fixing section 111 is adapted to the connection part of the stove bottom shell 3, and preferably connected by screws, such as Figure 6 As shown, the fixing section 111 is provided with screw mounting holes 113 for screw connection. The fixing frame 11 also includes a connecting section 112, whose lower end is connected to the fixing section 111 and the other end extends upward to be connected to the annular connecting member 13, thereby forming an integral structure.

[0097] Similarly, the angle β formed between the fixed section 111 and the connecting section 112 is also set at 70°-110°, preferably 80°-100°, more preferably 85°-95°, and most preferably 90°. Such an angle design enables the fixed section 111 to form a stable mechanical structure with the connecting section 112 after being connected to the stove bottom shell 3. When bearing the gravity of the hanging stove bottom shell, the force can be evenly transmitted to the entire connecting arm through a reasonable angle configuration, reducing the situation of excessive local force, enhancing the overall stability and reliability of the connecting arm, and ensuring that the stove can remain stable under various conditions of use.

[0098] A further solution is that the fixing frame 11, the hanging frame 12 and the annular connecting member 13 are an integrally formed structure;

[0099] Preferably, the fixing frame 11, the hanging frame 12 and the annular connecting member 13 are sheet metal structures formed by integrally bending spring steel.

[0100] From the manufacturing process point of view, the one-piece structure of the suspension bracket, fixing bracket and annular connector, especially the sheet metal structure formed by one-piece bending of spring steel, 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 reduces the difficulty of assembly by utilizing its own elasticity, ensuring the reliability and safety of the stove bottom shell during installation.

[0101] like Figure 3 and Figure 7 As shown, the structure of the stove bottom shell 3 of the present invention generally includes a bottom plate 31 for carrying the burner 2 and other parts and a peripheral wall 32 extending upward from the bottom plate 31. The bottom plate 31 is processed with concave and convex shapes to enhance its strength. The peripheral wall 32 is provided with a ventilation structure. The ventilation structure is generally designed as a ventilation hole 33 or the peripheral wall is designed in sections, and ventilation is performed using the gap between the two sections. The embodiment of the present invention adopts a method of stamping an inwardly convex shape on the bottom plate 31 of the stove bottom shell to fix the burner 2 (see Figure 7 ), the cooker bottom shell 3 also has an assembly portion 30, the main function of the assembly portion 30 is to install the above-mentioned connecting bracket 1, the structure and connection method of the assembly portion 30 are not limited, if screws are used for fixing, the assembly portion 30 can be a screw hole on the cooker bottom shell, so that the fixing section 111 of the fixing frame 11 is provided with a screw installation hole 113 (see Figure 6 ); if plug-in is adopted, the assembly part can be a socket on the bottom shell of the stove. There are many connection methods, which are not listed here one by one. In the embodiment of the present invention, the fixing frame 11 and the bottom shell 3 of the stove are preferably connected by screws, and the assembly part 30 is a screw hole. In addition, the assembly part 30 can be directly or indirectly arranged on the bottom shell of the stove, that is, the assembly part can be directly arranged on the bottom shell of the stove, and can also be installed on the bottom shell of the stove through an adapter. In the embodiment of the present invention, the assembly part 30 is preferably arranged on the bottom plate 31 of the bottom shell of the stove.

[0102] In terms of the specific structure and installation form of the assembly part 30, the assembly part 30 can also be arranged on a fixing frame, and then the fixing frame is fixed on the chassis 31 of the bottom shell of the stove (not shown in the figure), so as to ensure that a high degree of stability and reliability can be maintained under various use environments and working conditions. Further optimization design shows that the burner 2 and the corresponding assembly part 30 arranged on the outside thereof are jointly arranged on the same fixing frame. This integrated installation strategy significantly improves the compactness and coordination of the structure, makes the connection between the components tighter and the cooperation more tacit, and effectively reduces the potential risks such as structural looseness or unstable connection caused by the scattered installation of components. More preferably, the number of fixing frames and the number of burners 2 present a one-to-one precise relationship, and each fixing frame is firmly supported on the chassis 31 of the bottom shell of the stove, thereby constructing a stable and orderly internal support frame, and at the same time, enhancing the strength of the bottom shell of the stove, ensuring the balanced distribution of the weight of the bottom shell of the stove, and providing a solid structural guarantee for the long-term stable operation of the entire stove.

[0103] like Figures 3 to 5 As shown, the stove without a cooktop of the present invention comprises:

[0104] The adjustable panel 61 has a unique feature of being adjustable up and down on the top of the stove bottom shell 3. The adjustable panel 61 is provided with an adjustable panel mounting hole 611 for the support arm 12 and the burner head 2 to pass smoothly from bottom to top. This design structure enables the adjustable panel 61 to flexibly adjust its height position according to different installation requirements and usage scenarios, thereby adapting to the installation requirements of various countertops of different thicknesses, greatly broadening the application scope and adaptability of stoves without a stovetop.

[0105] The adjusting component 62 is connected to the adjustable panel 61 and is used to adjust the distance between the adjustable panel 61 and the table top 4 so as to make the adjustable panel 61 abut against the lower surface of the table top 4 .

[0106] The above structure is designed to closely cooperate with the support arm 122 in the connecting bracket 1, and together clamp the table top 4 between the support arm 122 and the adjustable panel 61, so as to improve the stability of the stove bottom shell 3 suspended under the table top.

[0107] The present invention cleverly uses the key feature that the adjustable panel can be adjusted up and down to significantly improve the performance of the stove without a cooktop from two core dimensions. First, when faced with a wide variety of countertops with different thicknesses on the market, the stove without a cooktop can easily achieve adaptive installation with the help of this feature of the adjustable panel. Whether it is an ultra-thin countertop or an ultra-thick countertop, the stove and the countertop can be perfectly combined through simple adjustment operations, which greatly improves the versatility and adaptability of the product in different kitchen environments and effectively reduces the installation restrictions and inconvenience caused by differences in countertop thickness. Second, through a close synergistic mechanism with the support arm, the countertop can be firmly clamped between the support arm and the adjustable panel to form a stable overall structure. This stable clamping structure fundamentally and effectively solves the potential risk of the bottom shell of the stove falling off the countertop due to possible shaking. During daily use, whether it is slight vibrations during cooking or accidental collisions in the kitchen environment, it will not easily destroy the stability of the connection between the stove and the countertop, thereby greatly improving the overall stability and reliability indicators of the cooktopless stove after installation, providing users with a safer, more durable and worry-free use experience.

[0108] A further solution is, Figure 4 and Figure 5 As shown, the adjustment component 62 mainly includes:

[0109] The support frame 621 is connected to the adjustable panel 61; preferably, both of them have pin holes 620 and 610, and 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;

[0110] The adjusting rod 622 is used to install the supporting frame 621 on the stove bottom shell 3, and drive the adjustable panel 61 to move up and down by adjusting the relative height between the supporting frame 621 and the bottom plate 31 of the stove bottom shell.

[0111] The support frame 621 includes a side wall 6211 and a bottom wall 6212. The side wall 6211 extends upward and is connected to the adjustable panel 61, and the bottom wall 6212 establishes an adjustable connection relationship with the bottom plate 31 of the stove bottom shell 3 through the adjustment rod 622, and the upper and lower distances between the bottom wall 6212 and the bottom plate 31 of the stove bottom shell are flexible and adjustable. Preferably, the support frame 621 is an integrated structural member formed by bending a sheet metal part to form the side wall 6211 and the bottom wall 6212, so as to improve its supporting strength.

[0112] In order to ensure the convenience and stability of the connection between the adjustable panel 61 and the support frame 621, a downwardly protruding connection portion 612 is provided on the lower surface of the adjustable panel 61. The connection portion 612 is preferably an integral structural member formed by bending downward at both ends of the adjustable panel 61. The integrally formed design of the connection portion not only reduces the number of parts and reduces the complexity of assembly, but also enhances the strength and stability of the connection part, effectively avoiding the potential safety hazards and performance degradation problems caused by loose connection or separation of parts.

[0113] 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, the two can be easily assembled, usually using pins or bolts as the connection means, and the pin holes 610, 620 or bolt installation holes are correspondingly arranged on the connecting portion 612 of the adjustable panel and the side wall 6211 of the support frame.

[0114] The ventilation design is of vital importance in ensuring the combustion efficiency of the stove. In order to avoid affecting the ventilation effect inside and outside the stove, a vent 6120 is designed on 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, which is used to cooperate with the ventilation hole 33 of the peripheral wall 32 of the stove bottom shell to form a through ventilation channel. This ventilation channel can effectively discharge the combustion exhaust gas, introduce fresh air, maintain the air pressure balance and suitable temperature environment inside the stove, thereby improving the performance stability and reliability of the entire stove and extending the service life of the product.

[0115] In terms of the design of the connection structure between the support frame 621 and the stove bottom shell 3, in order to achieve a convenient and fast assembly process, a matching pre-installed structure is provided between the two. Specifically, a claw 6213 extending upward is provided on the bottom wall 6212 of the support frame 621, and a claw perforation (not shown in the figure) is correspondingly provided on the chassis 31 of the stove bottom shell. The claw 6213 is preferably a spring structure, the upper end of the claw 6213 is bent toward the side wall 6211, and the distance between the upper end of the claw 6213 and the side wall 6211 is less than the distance between the lower end and the side wall 6211. When performing the connection operation between the support frame and the stove bottom shell, first align the claw of the support frame and pass through the claw perforation of the bottom shell of the stove. Since the claw has a certain elastic deformation ability, in the process of passing through the claw perforation, the claw will undergo moderate elastic deformation. After the claw passes through the claw perforation, it can reopen by relying on its own elastic recovery force, thereby forming a stable pre-installed structure. This pre-installation method does not require the use of complex tools or additional connecting parts. Only through the clever cooperation of the claws and the perforations, the initial positioning and connection can be quickly achieved, which greatly improves the assembly efficiency. After the pre-installation is completed, the adjustment rod is used to connect the support frame to the bottom shell of the stove. Since the claws pass through the bottom shell of the stove, the design of the pre-installation structure will not affect the adjustment of the relative height between the support frame and the bottom shell of the stove by the adjustment rod, which further ensures the stability and reliability of the entire connection structure.

[0116] In terms of the type of adjustment rod 622, it is preferred to use a screw rod, which has high-precision adjustment characteristics. The screw rod and the support frame or the bottom shell of the stove are closely matched through a threaded connection. With the help of the mature and precise transmission principle of spiral transmission, the vertical distance between the support frame and the bottom shell of the stove can be accurately fine-tuned. Through this structural design, the entire adjustment component can adjust the position of the adjustable panel in real time with a highly flexible and precise control strategy, thereby effectively adapting to different installation requirements and diversified usage scenarios, providing a solid technical guarantee for the stable operation of the stove without a cooktop in different countertop environments.

[0117] like Figure 3 and Figure 8 As shown, the stovetop-less cooker of the present invention includes a knob installation assembly 7, which mainly includes:

[0118] At least a part of the knob mounting sleeve 71 is used to play a key role in supporting the table 4. A through hole 710 is provided in the knob mounting sleeve 71 to install the knob shaft and / or the valve stem 81 of the switch valve 8.

[0119] The knob bracket 72 has at least a portion thereof disposed under the countertop and fixedly connected to the stove bottom shell 3, thereby constructing a reliable basic support frame for the entire knob installation assembly; the knob installation sleeve 71 and the knob bracket 72 are detachably connected.

[0120] The height of the knob mounting sleeve 71 relative to the knob bracket 72 is adjustable. That is to say, the upper and lower distances between the upper end of the knob mounting sleeve 71 and the knob bracket 72 are adjustable. This adjustable distance feature enables the assembly to be flexibly adapted to countertops of different thicknesses, further expanding the versatility and adaptability of stoves without cooktops in a variety of installation environments. Whether it is an ultra-thin countertop or a thicker countertop, the knob mounting assembly can be perfectly matched with the countertop through simple adjustment operations, ensuring that the knob can maintain a good operating feel and ease of use at different countertop heights.

[0121] In addition, the knob mounting sleeve 71 can be partially supported above the table top 4, and is detachably connected to the knob bracket 72 below the table top 4, and the upper and lower distances are adjustable. This design enables the knob mounting assembly to also have the function of clamping the table top.

[0122] There are multiple options for the position where the knob mounting sleeve 71 is connected to the knob bracket 72, which can be located above the table 4 and / or in the knob mounting hole 42 of the table and / or below the table 4. If the knob mounting sleeve 71 is entirely above the table 4, the upper end of the knob bracket 72 passes through the knob mounting hole 42 of the table from the bottom of the table 4 to connect with the knob mounting sleeve 71; if the knob bracket 72 is entirely below the table 4, the lower end of the knob mounting sleeve 71 passes through the knob mounting hole 42 of the table from the top of the table 4 to connect with the knob bracket 72; if the lower end of the knob mounting sleeve 71 is inserted into the knob mounting hole 42 of the table from the top of the table 4 to the bottom, and the upper end of the knob bracket 72 is inserted into the knob mounting hole 42 of the table from the bottom of the table 4 to the top, the lower end of the knob mounting sleeve 71 is connected with the upper end of the knob bracket 72 in the knob mounting hole 42 of the table. The above installation positions are only examples and are not exhaustive. They can be combined according to the actual structure of the knob installation sleeve and the knob bracket.

[0123] This multi-position optional 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 cooktopless stoves in various usage scenarios.

[0124] A further solution is that the knob mounting sleeve 71 includes a cylindrical connector 711 and a support ring 712 arranged 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 on the table 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, which is threadedly connected to the connector 711, or is an integral structure with the connector 711.

[0125] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by threads.

[0126] Preferably, the knob bracket 72 includes a mounting frame 721 fixedly connected to the stove bottom shell 3 and a connecting sleeve 722 provided on the mounting frame 721 and protruding upward. The connecting sleeve 722 is used to extend into the knob mounting hole 42 of the tabletop and connect to the connector 711 of the knob mounting sleeve 71. The outer diameter of the connecting sleeve 722 preferably matches the knob mounting hole 42 of the tabletop. The connecting sleeve 722 has an internal thread, and the lower end of the connector 711 of the knob mounting sleeve 71 is provided with an external thread, which can match the connecting sleeve 722. When installing, tightening the threaded match can achieve the connection and fixation of the stove bottom shell 3 and the tabletop 4 at the knob. Further preferably, the connecting sleeve 722 is fixed to the mounting frame 721 by screws or pins, or the connecting sleeve 722 and the mounting frame 721 are an integral structure.

[0127] The threaded connection has significant advantages such as stable connection, precise adjustment, and convenience. The present invention uses the innovative design of the knob installation assembly to further significantly improve the stability of the stove bottom shell fixedly installed under the countertop. By flexibly adjusting the upper and lower relative distances between the knob installation sleeve and the knob bracket, as well as the multi-position optional connection method and the stable characteristics of the threaded connection, the assembly can perfectly adapt to countertops of different thicknesses and different design styles, further comprehensively improving the versatility and adaptability of stoves without cooktops in a variety of complex installation environments, providing users with a more convenient, safe and stable use experience.

[0128] Further, such as Figure 4 As shown, the adjustable panel 61 is provided with an adjustable panel knob mounting hole 613 , and 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 top 4 , and is connected to the connector 711 of the knob mounting sleeve 71 .

[0129] like Fig. 9 As shown, the installation method of the stove without a cooktop according to the present invention mainly includes the following steps:

[0130] S1. Install the connected adjustable panel 61 and the adjusting component 62 on the bottom shell 3 of the cooker.

[0131] Before or after step S1, the stove top 2, knob bracket 72, switch valve 8 and other internal parts of the stove and the connecting bracket 1 are installed on the stove bottom shell 3, ensuring that the distance between the adjustable panel 61 and the support arm 122 is much larger than the thickness of the table top 4, and preferably the adjustable panel is adjusted down to the limit position. The above operation completes the assembly of the internal structure of the stove in advance, provides convenience for the subsequent overall installation, and avoids inconvenience or interference caused by the lack of internal parts or failure to install them in place during the subsequent installation process.

[0132] S2. Lift the stove bottom shell 3 under the countertop 4, and the guide arm 123 at the upper end of the hanging bracket 12 of the connecting bracket 1 abuts against the hole wall at the lower end of the countertop mounting hole 41. The inclined guide arm 123 converts the abutting reaction force into a force that makes the hanging bracket 12 move toward the central axis direction of the annular connecting member 13, so that the support arm 122 passes through the countertop mounting hole 41 upward from the bottom of the countertop 4. After the support arm 122 passes through the countertop mounting hole 41, the reaction force of the countertop on the support arm 122 and the guide arm 123 disappears, and the support arm 122 is reset outward, thereby supporting the outer periphery of the countertop mounting hole 41, and the stove bottom shell 3 is suspended under the countertop 4 (see Fig.10 ).

[0133] In this step, the cooker bottom shell 3 is carefully lifted, and care should be taken to keep the cooker bottom shell stable to avoid damage to components or installation difficulties due to shaking or tilting. In this process, the installer needs to control the strength and angle to ensure that the support arm can accurately align with the tabletop installation hole.

[0134] S3, operate the adjusting component 62, adjust the height of the adjustable panel 61 upwards, make it contact with the lower surface of the table 4, and preliminarily fix the stove bottom shell 3 through the cooperation with the support arm 122. This step can further enhance the stability of the stove bottom shell installation, reduce the possibility of shaking, ensure the firmness and safety of the entire stove without a cooktop after installation, and lay a good foundation for subsequent fine debugging and use.

[0135] Then, install the knob installation sleeve 71 on the table 4, connect the knob installation sleeve 71 with the knob bracket 72, install the knob 82, fix the liquid tray 5 on the burner 2, preferably by screwing and fixing; then install the ignition cover 21 and the pot bracket 9, and complete the installation of the stove without a stove top on the table (see Figure 1 and Figure 2 ).
