Description

Technical Field

[0001] The invention belongs to the technical field of gas stoves, and in particular relates to a connecting frame of a stove without a stove top, a stove without a stove top 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] However, the stove without a cooktop has the defect of insufficient load-bearing capacity: the stove bottom shell that carries the stove head and other parts is suspended under the table top. Specifically, the upper edge of the outer peripheral side wall of the stove bottom shell is provided with a flange extending horizontally outward, and the flange is connected to the table top through a connecting component; because the main parts of the stove are concentrated in the middle area of ​​the stove bottom shell, the center of gravity of the stove is far away from the connecting components, which not only increases the torque, but also makes the angle between the center of gravity and the connecting line of the connecting components and the vertical direction larger, which causes the connecting components to bear the vertical gravity while also needing to Bearing horizontal pulling force, the connecting parts are prone to horizontal deformation, which may cause the connecting parts to separate from the countertop, or even cause the entire bottom shell of the stove to fall off, which not only affects the user's use, but also creates a safety hazard. In addition, the chassis of the bottom shell of the stove is not supported. After long-term use, the chassis surface is prone to deform downward, causing the stove head to shift in position, and in severe cases, the stove head may break, causing natural gas leakage, seriously endangering the user's life safety, and causing users to have concerns when purchasing stoves.

[0004] The applicant has improved the installation structure of a stove without a stovetop. The Chinese patent application number CN202323210764.7 discloses a stove without a stovetop, 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 soaking plate is fixed on the lower surface of the countertop, and a connector with a protruding surface and extending downward is provided on the lower surface of the soaking plate, which is connected to the bottom plate of the stove basin, so that the stove basin is suspended and fixed below the countertop.

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

[0006] The first installation structure requires first fixing the connector to the soaking plate, then gluing the soaking plate to the bottom of the countertop, and then fixing the stove basin to the connector under the countertop. During the installation process, the stove basin needs to be lifted and fixed to the connector 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 structure firstly adheres the corresponding position of the soaking plate to the lower surface of the countertop; the second step is to further clamp and fix the soaking plate 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 to 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] In view of this, the present invention is proposed. Summary of the invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings 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 connecting rack for a stove without a cooktop to simplify the installation steps and hang the bottom shell of the stove under the countertop at one time.

[0010] The second object of the present invention is to provide a connection frame for a stove without a cooktop, which structure retracts the support arm by lateral movement to shrink the volume so that it can smoothly pass through the tabletop installation hole, and then moves the support arm in the opposite direction to extend it and then support it on the tabletop.

[0011] The third object of the present invention is to provide a stove without a cooktop using the above-mentioned connecting frame.

[0012] A fourth object of the present invention is to provide a stove without a cooktop, which can reduce the distance between the connecting frame 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.

[0013] A fifth 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.

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

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

[0016] A connecting frame for a stove without a cooktop is used to hang a bottom shell of the stove under a tabletop. The connecting frame comprises:

[0017] A connecting arm, used for connecting with the bottom shell of the cooker;

[0018] The supporting arm is used for supporting on the table top, and the supporting arm is movably and telescopically mounted on the connecting arm.

[0019] The present invention can hang the stove bottom shell carrying stove parts such as a burner under the table top in a one-time and stable manner through the connecting frame. The connecting arm of the connecting frame is mainly used to first firmly connect with the stove bottom shell to lay the foundation for the subsequent hanging operation; the supporting arm of the connecting frame is connected to the connecting arm in a movable and telescopic manner, and this connection method gives the supporting arm a movable and telescopic scale. The supporting arm is retracted toward the connecting arm by using the movable scale to smoothly pass through the table top installation hole from under the table top, and then extend above the table top to form an effective support, thereby ensuring the stability and reliability of the entire stove connecting frame.

[0020] A further solution is that the support arm has at least two states relative to the connecting arm, including:

[0021] In the first state, the support arm moves and contracts toward the connecting arm, and can enter the table top mounting hole from the bottom of the table top upward;

[0022] In the second state, the support arm moves in the reverse direction and extends the connecting arm to support the outer periphery of the table top mounting hole.

[0023] In the first state, the support arm retracts toward the connecting arm, thereby reducing its own volume, so that it can smoothly extend into the table top mounting hole from under the table top, providing possibility for subsequent installation of the support arm through the table top mounting hole.

[0024] In the second state, after the support arm passes through the countertop mounting hole, the support arm moves in the opposite direction to the first state and extends the connecting arm, so that it can be supported on the peripheral area of ​​the countertop mounting hole. In this way, reliable supporting force and stability are provided for the connecting frame of the entire stove without a cooktop, ensuring that the stove can remain stable during use without shaking, displacement or other adverse conditions.

[0025] A further solution is that the connecting frame includes an elastic member for providing an elastic force for the support arm to switch from the first state to the second state;

[0026] Preferably, the elastic member is a compression spring;

[0027] Preferably, one end of the compression spring is connected to the support arm, and the other end is connected to the connecting arm.

[0028] When the support arm of the above-mentioned structure switches from the first state to the second state, the compression spring can effectively transfer the stored elastic potential energy to the support arm based on its own elastic deformation characteristics, driving the support arm to complete the action of moving and extending the connecting arm, thereby realizing a smooth switching of states, so that the connecting frame can more flexibly and efficiently perform its supporting and connecting functions in actual applications, reducing problems such as jamming, wear or shaking that may be caused by manual operation of switching states.

[0029] A further solution is that a guide member is provided between the support arm and the connecting arm to guide the support arm to move and extend along a preset direction;

[0030] Preferably, the guide member includes an anti-slip groove for preventing the support arm from detaching from the connecting arm when the support arm moves telescopically;

[0031] Preferably, the anti-slip groove is provided on the connecting arm, and the supporting arm is movably installed in the anti-slip groove;

[0032] Preferably, the anti-slip groove comprises two transverse U-shaped grooves, the openings of the two transverse U-shaped grooves are arranged opposite to each other, and the two side edges of the support arm are correspondingly installed in the two transverse U-shaped grooves;

[0033] Preferably, the two transverse U-shaped grooves are formed by integrally bending two sides of the connecting arm.

[0034] The guide member of the present invention effectively guides the support arm to move in a preset direction to ensure the movement accuracy and stability of the support arm, thereby ensuring the continuity of the entire movement of the bottom shell of the suspended stove. The design of the anti-slip groove effectively prevents the support arm from detaching from the connecting arm during extension and retraction, thereby ensuring the integrity and reliability of the structure and enhancing the safety of use. The anti-slip groove is located on the connecting arm and the support arm is movably installed therein, thereby optimizing the fit between the components. The design of the two horizontal U-shaped grooves, with the openings facing each other and clamping the two side edges of the support arm, further limits the displacement deviation of the support arm and makes its movement smoother. The two sides of the connecting arm are integrally bent to form a U-shaped groove, which not only simplifies the manufacturing process and improves production efficiency, but also enhances the structural strength of the connecting arm, so that it can better withstand working stress and extend the service life of the connecting frame.

[0035] A further solution is that the support arm includes:

[0036] The assembly section moves in the anti-slip groove;

[0037] The telescopic section is connected to the assembly section, and at least partially retracts into the anti-slip groove in the first state of the support arm, and extends out of the anti-slip groove in the second state of the support arm;

[0038] Preferably, the width of the assembly section is greater than the width of the telescopic section, and a blocking portion is provided at one end of the U-shaped groove in the direction in which the telescopic section extends, for preventing the assembly section from escaping from the anti-slip groove from the end;

[0039] Preferably, the support arm further comprises a guide section connected to the telescopic section, and the guide section extends upwardly and in a reverse direction from one end extending from the telescopic section.

[0040] In the design structure of the above-mentioned support arm, the assembly section is limited to move in the anti-slip groove, which ensures the stability and accuracy of the extension and retraction of the support arm. It is wider than the extension section and a blocking part is designed at the end of the U-shaped groove to effectively prevent it from detaching, enhance the structural reliability and reduce the risk of failure. The reverse tilt and upward extension design of the guide section can not only play a good role in guiding the support arm into the countertop installation hole when it retracts, but also improve the overall strength of the support arm, improve the overall performance and service life of the connecting frame, and provide assistance for the stable suspension of stoves without cooktops.

[0041] A further solution is that the connecting arm includes:

[0042] A mounting portion, used for mounting a support arm;

[0043] A fixing part, used for fixing and connecting with the bottom shell of the cooker;

[0044] A connecting portion, one end of which is connected to the fixing portion, and the other end of which is connected to the mounting portion;

[0045] Preferably, an angle α is formed between the mounting portion and the connecting portion, α is 70°-110°, preferably α is 80°-100°, and more preferably, α is 85°-95°;

[0046] Preferably, an angle β is formed between the fixing portion and the connecting portion, β is 70°-110°, preferably β is 80°-100°, and more preferably, β is 85°-95°;

[0047] Preferably, the mounting portion and the fixing portion extend in opposite directions at two ends of the connecting portion;

[0048] Preferably, the connecting arm is a sheet metal part that is integrally bent to form a mounting portion, a fixing portion and a connecting portion.

[0049] In the design structure of the connecting arm of the present invention, the mounting part provides a precise mounting position for the supporting arm to ensure the stable operation of the supporting arm, thereby ensuring the overall stability of the connecting frame; the fixing part is firmly connected to the bottom shell of the stove to enhance the integrity of the stove installed on the countertop; the connecting part effectively connects the various parts to optimize the conduction of force. The specific angle range between the mounting part and the connecting part, and between the fixing part and the connecting part optimizes the mechanical distribution and can reduce stress concentration; the mounting part and the fixing part extend in opposite directions to improve the compactness and balance of the structure; the integrated bent sheet metal design reduces the number of parts, reduces production costs, and also improves production efficiency and structural strength.

[0050] The invention provides a stove without a cooktop, comprising a stove bottom shell. The stove bottom shell is provided with an assembly part for installing the above-mentioned connecting frame.

[0051] A further solution is that the stove bottom shell is provided with at least two assembly parts;

[0052] Preferably, at least two assembly parts form a group and are distributed around the outer circumference of the same burner on the bottom shell of the cooker. Also preferably, at least two assembly parts around the outer circumference of the same burner are evenly distributed in the same circumferential direction.

[0053] Alternatively, the two assembly parts are mounted on one side of the two burners in a one-to-one correspondence and are substantially in the same straight line with the centers of the two burners.

[0054] Preferably, the assembly portion is arranged on a fixing frame, and the fixing frame is fixedly connected to the bottom shell of the cooker.

[0055] Further preferably, the furnace head and the corresponding assembly portion arranged on the outer side thereof are installed on the same fixing frame.

[0056] More preferably, the number of the fixing frames corresponds one to one with the number of the furnace heads.

[0057] A further solution is that the stove without a cooktop of the present invention includes a clamping assembly, which is arranged below the tabletop and cooperates with the support arm to clamp the tabletop between the support arm and the clamping assembly;

[0058] Preferably, the clamping assembly comprises,

[0059] An adjustable panel is arranged above the bottom shell of the cooker in an adjustable manner, and the adjustable panel is provided with an adjustable panel mounting hole for the support arm and the burner to pass through from bottom to top;

[0060] The adjusting component is connected with the adjustable panel, can adjust the distance between the adjustable panel and the supporting arm, and is used for clamping the table top between the supporting arm and the adjustable panel.

[0061] The present invention makes use of the characteristic that the adjustable panel in the clamping assembly can be adjusted up and down, so that, on the one hand, the stove without a cooktop can easily meet the installation requirements of various countertops with different thicknesses; on the other hand, it can also cooperate with the support arm to firmly clamp the countertop between the support arm and the clamping assembly, effectively solving the problem of the stove bottom shell falling off the countertop due to shaking, and greatly improving the stability and reliability of the stove without a cooktop after installation.

[0062] Further, the adjusting component includes,

[0063] a support frame connected to the adjustable panel;

[0064] 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;

[0065] Preferably, 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 adjusting rod, and the upper and lower distances between the bottom wall and the bottom shell of the stove are adjustable;

[0066] Preferably, the support frame is arranged 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 adjustment rod passes through the bottom wall and is connected to the bottom shell of the stove;

[0067] Preferably, the adjusting rod comprises a screw, which is threadedly connected to the supporting frame or the bottom shell of the stove, and the vertical distance between the supporting frame and the bottom shell of the stove is adjusted through screw transmission.

[0068] 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.

[0069] The spiral transmission principle of the adjustment rod is further used to accurately adjust the upper and lower distances between the support frame and the bottom shell of the stove, thereby ensuring that the clamping assembly can stably and effectively perform its clamping function on the countertop, thereby improving the stability and reliability of the overall structure of the stove without a cooktop.

[0070] 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:

[0071] a knob mounting sleeve, at least partially adapted to be supported above a countertop;

[0072] The knob bracket is at least partially arranged under the countertop and fixedly connected to the bottom shell of the stove;

[0073] The knob mounting sleeve is detachably connected to the knob bracket;

[0074] Preferably, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0075] 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;

[0076] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0077] 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.

[0078] The present invention also provides a method for installing a stove without a cooktop, comprising the following steps:

[0079] S1, connecting the connecting arm of the connecting frame to the assembly part of the bottom shell of the stove;

[0080] S2, lift up the bottom shell of the cooker under the countertop, move the support arm, and retract it toward the connecting arm, so that the support arm passes upward through the countertop mounting hole from under the countertop;

[0081] S3. After the support arm passes through the countertop mounting hole, it moves in the reverse direction, extends from the connecting arm, and is supported on the periphery of the countertop mounting hole, so that the bottom shell of the cooker is suspended under the countertop.

[0082] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0083] 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 table through the connecting frame, which greatly simplifies the installation steps, improves the installation efficiency and convenience, and effectively reduces the manpower and time costs during the installation process.

[0084] The connecting frame adopts a design of telescopic movement and state switching of the support arm relative to the connecting arm: the support arm retracts the connecting arm to extend into the countertop mounting hole, and extends the connecting arm to support the outer periphery of the countertop mounting hole. This not only facilitates the one-time hanging installation of the stove bottom shell, but also makes the installation of the stove bottom shell stable and reliable, effectively solves the problem of falling off caused by shaking, and ensures safe installation and use.

[0085] 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.

[0086] In addition, the adjustment component of the clamping assembly drives the adjustable panel to move through the cooperation of the support frame and the adjustment rod. The structural design is reasonable and the adjustment process is relatively simple, which is conducive to quickly adjusting to the appropriate position to clamp the table top during installation, thereby improving installation efficiency.

[0087] 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.

[0088] 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.

[0089] The installation method of the stove without a cooktop of the present invention comprises the following steps: firstly, the connecting arm of the connecting frame is connected to the bottom shell of the stove; then, the bottom shell of the stove is simply lifted up under the table top, and the supporting arm of the connecting frame is abutted against the hole wall at the lower end of the table top installation hole, so that the supporting arm is retracted, the connecting arm enters the table top installation hole, and after passing through the table top installation hole, the connecting arm is extended again to support above the table top, so that the bottom shell of the stove can be suspended and installed under the table top. The operation is simple, the installation difficulty is reduced, and it is convenient for the installers to quickly master and implement it.

[0102] 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

[0103] 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.

[0104] 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.

[0105] 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.

[0106] like Figure 1 and Figure 2 As shown, the connecting frame 1 of the stove without a cooktop of the present invention is used to hang the stove bottom shell 3 carrying many parts such as the burner head 2 under the table 4 at one time and firmly (see Fig. 9 and Fig.10 ), when implementing the operation process of hanging the stove bottom shell 3, the installer does not need to lift the stove bottom shell 3 and connect the connecting frame 1 to the stove bottom shell 3 at the same time, or does not need to lift the stove bottom shell 3 and connect the components of the connecting frame 1 at the same time, and other complicated and inconvenient actions. This feature greatly simplifies the installation process, improves the installation efficiency, and also reduces the potential safety hazards and installation quality problems caused by improper human operation, making the installation process of the stove without a cooktop more convenient, efficient and reliable.

[0107] The connecting frame 1 of the present invention is presented as a complete integrated connecting structure, including a connecting arm 11 and a supporting arm 12. The connecting arm 11 is used to connect to the stove bottom shell 3, and the supporting arm 12 is used to assume the role of passing through the countertop mounting hole 41 from below the countertop 4 to support on the countertop 4. The supporting arm 12 and the connecting arm 11 are connected in a movable and telescopic manner. The supporting arm 12 is movable and telescopic relative to the connecting arm 11, so that the supporting arm 12 moves toward the connecting arm 11 to shrink its volume, and can smoothly pass through the countertop mounting hole 41 from below the countertop, and then extend the connecting arm 11 by moving in the opposite direction, and stably support the countertop 4 on the periphery of the countertop mounting hole 41, thereby achieving the purpose of suspending the stove bottom shell 3 below the countertop 4.

[0108] The support arm 12 presents at least two different states relative to the connecting arm 11: one is the first state, in which the support arm 12 retracts toward the connecting arm 11, thereby reducing the volume it occupies, creating favorable conditions for the support arm 12 to smoothly penetrate into the countertop mounting hole 41 from under the countertop 4, and providing a practical possibility for the subsequent installation action of the support arm 12 to successfully pass through the countertop mounting hole 41; the other is the second state, after the support arm 12 passes through the countertop mounting hole 41, the support arm 12 moves in the opposite direction and extends out of the connecting arm 11, and can be firmly supported on the countertop outside the countertop mounting hole 41. This ingenious design provides a solid and reliable support force and stability guarantee for the entire connection frame of the stove without a cooktop, effectively ensuring that the stove can always maintain a stable state during use, and preventing the occurrence of undesirable phenomena such as shaking or displacement.

[0109] In a further solution, the connecting frame 1 includes an elastic member 13, the main function of which is to provide the necessary elastic force for the support arm 12 to change from the first state to the second state.

[0110] In a preferred design, the elastic member 13 is a compression spring. One end of the compression spring is connected to the support arm 12, and the other end is connected to the connecting arm 11. Figure 1 As shown, a protrusion 16 is provided on the connecting arm 11 at a certain distance from the support arm 12 in the retracting direction of the support arm 12, one end of the compression spring abuts against the protrusion 16, and the other end abuts against one end of the support arm 12 in the retracting direction. Preferably, the protrusion 16 is a baffle structure stamped out of the support arm.

[0111] The above design enables the compression spring to assist the support arm 12 in smoothly switching from a first state in which the connecting arm 11 is retracted to a second state in which the connecting arm 11 is extended from the connecting arm 11 and supported on the table surface outside the table mounting hole 41, based on its own elastic characteristics, during the state switching of the support arm 12. This further optimizes the working performance of the connecting frame, improves the stability and reliability of the installation of the stove without a cooktop, and to a certain extent makes the installation process smoother and more convenient, reduces problems such as jamming, wear or shaking that may be caused by manual operation switching, and makes the installation safer and more reliable.

[0112] In another embodiment, the connecting frame of the present invention can also eliminate the design of the elastic member, and the support arm can be extended from the connecting arm by manual control of the installer.

[0113] Furthermore, a guide is provided between the support arm 12 and the connecting arm 11, the purpose of which is to ensure that the support arm 12 can be smoothly moved and telescoped along a preset direction, thereby ensuring stable operation of the telescopic state switching of the support arm 12.

[0114] One structure adopted is that the guide member includes an anti-slip groove 14. The core function of the anti-slip groove 14 is to provide a reliable limit guarantee for the telescopic movement process of the support arm 12, effectively preventing the support arm 12 from accidentally detaching from the connecting arm 11 during movement, thereby avoiding safety hazards caused by the detachment of components and ensuring the integrity and reliability of the entire connecting frame.

[0115] Specifically, the anti-slip groove 14 is cleverly arranged on the connecting arm 11. Through sophisticated process design, the supporting arm 12 can be tightly and accurately installed inside the anti-slip groove 14 in a movable manner, forming a flexible and stable matching relationship between the two.

[0116] Further into the structural details of the anti-slip groove 14, it is composed of two horizontal U-shaped grooves (see Figure 1 ), the openings of the two U-shaped grooves are relatively arranged, so that the two side edges of the support arm 12 can be installed exactly in the two horizontal U-shaped grooves. This tight and symmetrical installation method allows the support arm 12 to be evenly constrained and guided by the U-shaped grooves on both sides during movement, greatly improving the stability and directionality of the movement of the support arm 12, and effectively avoiding the support arm from shaking left and right or deviating from the predetermined track during the extension and retraction process.

[0117] Preferably, the two transverse U-shaped grooves are carefully made by using an integrated bending process on both sides of the connecting arm 11. This integrated bending manufacturing method not only reduces the number of parts, simplifies the production process, and reduces the production cost, but also greatly enhances the connection stability between the connecting arm 11 and the anti-slip groove 14 in terms of structural strength and integrity, so that the entire structure can withstand greater external impact and workload, providing a solid and reliable basic guarantee for the long-term stable operation of the stove connection frame without a stovetop.

[0118] The structure of the support arm 12 of the present invention mainly includes:

[0119] The assembly section 121 can move inside the anti-slip groove 14. The anti-slip groove 14 provides a stable running track for it, and a proper gap is maintained between its inner wall and the assembly section 121, so that the assembly section 121 can slide smoothly and unimpeded during the movement without obvious shaking or deviation from the track.

[0120] The telescopic section 122 is connected to the assembly section 121. In the first state of the support arm 12, the telescopic section 122 can be at least partially retracted into the anti-slip groove 14 according to actual needs. The retraction process is stable and smooth, so that the support arm 12 can effectively reduce its own volume occupation when it needs to pass through a narrow space. For example, when it is necessary to enter the tabletop mounting hole 41 from the bottom of the tabletop 4, this retraction mechanism is particularly important, which provides the necessary conditions for the smooth progress of the entire installation process. When the support arm 12 is converted to the second state, the telescopic section 122 can quickly extend out of the anti-slip groove 14 to provide reliable support force for the periphery of the tabletop mounting hole 41, ensuring that the stove without a cooktop can be firmly maintained in a predetermined position during use, and will not cause unstable conditions such as shaking and displacement due to insufficient support, thereby ensuring the normal use and safety of the stove.

[0121] A preferred solution is to optimize the assembly structure of the support arm 12, and design the width L2 of the assembly section 121 to be larger than the width L1 of the telescopic section 122 (see Figure 1 ), this design facilitates installation into the anti-slip groove 14 from the end close to the elastic member 13. In addition, the U-shaped groove is carefully provided with a blocking portion 15 (see Figure 2 ). When the assembly section 121 moves in the anti-slip groove 14, the blocking portion 15 can effectively limit the movement range of the assembly section 121, preventing it from being separated from the anti-slip groove 14 from this end when subjected to external force or due to other unexpected circumstances. This design greatly improves the firmness and stability of the connection between the support arm and the connecting arm, so that the entire structure can remain intact and reliable in complex working environments and various working conditions, significantly reducing various risks caused by component detachment, providing a solid guarantee for the long-term stable operation of the stove without a cooktop, and improving the user experience and satisfaction.

[0122] Another preferred solution is that the support arm 12 also has a guide section 123, which is connected to the telescopic section 122. The guide section 123 starts from one end of the telescopic section 122 and is presented in a unique form of extending upward in a reverse tilt, and its tilt angle and extension length have been carefully designed and optimized. When the support arm 12 is performing a telescopic action and cooperating with the table mounting hole 41, the guide section 123 can contact the hole wall at the lower end of the table mounting hole 41, and guide the support arm 12 to enter the table mounting hole 41 more smoothly and steadily through its inclined surface, avoiding component damage and movement jamming caused by direct collision or friction.

[0123] The connecting arm 11 of the present invention includes a fixing portion 111 at its lower end, and the fixing portion 111 is used to be fixedly connected to the stove bottom shell 3. The fixing portion 111 is adapted to the connection portion of the stove bottom shell 3, and preferably connected by screws. Figure 1 As shown, the fixing portion 111 is provided with a screw mounting hole 113 for screw connection. The upper end of the connecting arm 11 is provided with a mounting portion 110, and the mounting portion 110 is used to mount the support arm 12. Specifically, the mounting portion 110 is provided with the above-mentioned anti-slip groove 14, blocking portion and protrusion 16. The connecting arm 11 also includes a connecting portion 112, the lower end of which is connected to the fixing portion 111, and the other end extends upward to be connected to the mounting portion 110, thereby forming an integral structure.

[0124] The angle α formed between the mounting portion 110 and the connecting portion 112 is limited to a range of 70°-110°, more preferably 80°-100°, more ideally 85°-95°, and most preferably 90°.

[0125] The above-mentioned angle design provides a suitable angle to support the movement and extension of the support arm 12 on the mounting portion 110, which can not only ensure that the support arm has sufficient room for movement, but also effectively disperse the force to the connecting portion 112 and the fixing portion 111 through a reasonable angle distribution when the support arm is subjected to external force, thereby avoiding stress concentration and improving the load-bearing capacity and service life of the entire connecting arm.

[0126] Similarly, the angle β formed between the fixing portion 111 and the connecting portion 112 is also set at 70°-110°, preferably 80°-100°, more preferably 85°-95°, and most preferably 90°. Such an angle design enables the fixing portion 111 to form a stable mechanical structure with the connecting portion 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 transferred 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.

[0127] Furthermore, the mounting portion 110 and the fixing portion 111 extend in opposite directions at the two ends of the connecting portion 112. This design enables the connecting arm to better adapt to the surrounding space environment when it is installed in the bottom shell of the stove, and avoids interference with other components. At the same time, this layout method also helps to form a mutually balancing force couple relationship between the mounting portion and the fixing portion during the force transmission process, further improving the stability and anti-deformation ability of the connecting arm, so that the entire connecting frame can work more reliably.

[0128] Furthermore, the connecting arm 11 adopts an integral bending process to form the mounting portion 110, the fixing portion 111 and the connecting portion 112. The integrally bent sheet metal has structural continuity and integrity, and there is no welding or splicing seam, thereby avoiding the problems of reduced strength and stress concentration that may be caused by weak connection parts. This integral structure can better withstand various complex external forces and ensure that the strength and rigidity of the connecting arm meet the use requirements.

[0129] The design structure of the connecting arm of the present invention provides a precise installation position for the supporting arm, ensuring the stable operation of the supporting arm, thereby ensuring the overall stability of the connecting frame; the fixing part is firmly connected to the bottom shell of the stove, enhancing the integrity of the stove installed on the table; the connecting part effectively connects the various parts to optimize the conduction of force. The specific angle range between the installing part and the connecting part, and between the fixing part and the connecting part optimizes the mechanical distribution and can reduce stress concentration; the installing part and the fixing part extend in opposite directions to improve the compactness and balance of the structure; the integrated bending sheet metal design reduces the number of parts, reduces production costs, and also improves production efficiency and structural strength.

[0130] like Figure 3 and Figure 7 As shown, the stove without a cooktop of the present invention comprises a stove bottom shell 3. The structure of the stove bottom shell 3 generally comprises a chassis 31 for carrying the burner 2 and other parts and a peripheral wall 32 extending upward from the four sides of the chassis 31. The chassis 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 stove bottom shell 3 has an assembly part 30. The main function of the assembly part 30 is to install the above-mentioned connecting frame 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 a screw hole on the stove bottom shell. In this way, the fixing part 111 of the connecting arm 11 is provided with a screw installation hole 113 (see Figure 1 ); 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, it is preferred that the connecting arm 11 and the bottom shell 3 of the stove are fastened and connected by 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, and can also be installed on the bottom shell of the stove through an adapter, which will be described in detail later.

[0131] In order to reduce the number of holes punched on the table 4, the table mounting hole 41 is the burner mounting hole of the stove, and of course it can also be the knob mounting hole 42 of the table, preferably the burner mounting hole. Of course, it can also be another perforation set on the table, and a decorative cover needs to be installed to cover the support arm 12 supported on the table. Similarly, for the burner mounting hole, it is necessary to use a burner decorative cover or a liquid tray 5 to cover the support arm 12 (see Fig.10 and 11 ).

[0132] A further design scheme for the assembly part 30 is the number and position of the assembly part 30 on the stove bottom shell 3. The number of the assembly parts 30 is related to the size, weight, shape and number of burners 2 of the stove bottom shell 3. In order to obtain a stable installation effect, the stove bottom shell 3 is provided with at least two assembly parts 30. In a highly advantageous layout mode, at least two assembly parts 30 are combined into a group and reasonably distributed around the periphery of a specific burner 2 on the stove bottom shell 3, especially a single burner stove or a multi-burner design with a burner in the center. Of course, for a stove with multiple burners, an assembly part can be arranged around each burner, or an assembly part can be arranged around two burners that play a balancing role on the stove. More ingeniously, these assembly parts around the periphery of the same burner are evenly distributed in the same circumferential direction. The preferred solution of the present invention is to arrange two assembly parts 30 around each burner 2, and the assembly parts 30 are distributed on both sides of the burner 2 in a symmetrical manner. This evenly distributed design is not accidental. It can achieve an ideal balanced force effect in the mechanical structure, effectively avoiding structural stability problems that may be caused by local uneven force. At the same time, it also achieves an optimized configuration in terms of spatial layout, making the entire internal structure of the stove more compact and reasonable.

[0133] Another feasible assembly part layout scheme (not shown in the figure) is that, under the premise that the connecting frame can meet the predetermined strength, for multi-burner stoves, in order to save costs, the number of connecting frames can be reduced, and the stove only needs to have an assembly part on one side of the two burners, the assembly part corresponds to the burners one by one, and the two assembly parts and the centers of the two burners are roughly on the same straight line, that is, the two assembly parts are between the two burners or outside the two burners; but it should be noted that in order to meet the lateral stability of the stove, it is necessary to have a rigid installation requirement for the installation angle of the connecting frame, especially the extension direction of the support arm, and the extension directions of the support arms of the two connecting frames are opposite to each other, that is, if the two assembly parts are set between the two burners, the extension directions of the support arms are set relative to each other, and if the two assembly parts are set outside the two burners, the extension directions of the support arms are set opposite to each other. This layout method shows unique adaptability and practicality under some specific stove design concepts and kitchen space planning requirements, and can further optimize the overall space occupancy and operational convenience of the stove on the basis of meeting basic installation requirements.

[0134] In terms of the specific structure and installation form of the assembly part 30, it is preferred that the assembly part 30 is arranged on a fixing frame 34, and the fixing frame 34 and the stove bottom shell 3 are fixedly connected 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 installed together on the same fixing frame 34. 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 34 and the number of burners 2 present a one-to-one precise relationship, and each fixing frame 34 is firmly supported on the chassis 31 of the stove bottom shell, thereby constructing a stable and orderly internal support frame, and at the same time, enhancing the strength of the stove bottom shell, ensuring the balanced distribution of the weight of the stove bottom shell, and providing a solid structural guarantee for the long-term stable operation of the entire stove.

[0135] A further solution is, Figure 4 , Figure 5 and Figure 7 As shown, the stove without a cooktop of the present invention includes a clamping assembly 6, which is arranged below the table top 4. The clamping assembly 6 is designed to closely cooperate with the support arm 12 in the connecting frame 1 to clamp the table top 4 between the support arm 12 and the clamping assembly 6, thereby improving the stability of the stove bottom shell 3 suspended below the table top.

[0136] The clamping assembly 6 mainly includes the following components:

[0137] The adjustable panel 61 has the unique property of being adjustable up and down on the top of the stove bottom shell 3, and 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.

[0138] 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 support arm 12 , so as to clamp the tabletop 4 between the support arm 12 and the adjustable panel 61 .

[0139] The present invention cleverly uses the key feature that the adjustable panel in the clamping assembly 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 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 the difference in countertop thickness. Second, through the close coordination mechanism with the support arm, the countertop can be firmly clamped between the support arm and the clamping assembly 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 the 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.

[0140] A further solution is, Figure 5 As shown, the adjustment component 62 mainly includes:

[0141] 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;

[0142] 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.

[0143] 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.

[0144] In order to ensure the convenience and stability of the connection between the adjustable panel 61 and the support frame 621, a downwardly protruding connecting plate 612 is provided on the lower surface of the adjustable panel 61. The connecting plate 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 connecting plate 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.

[0145] 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 connecting plate 612 of the adjustable panel and the side wall 6211 of the support frame are correspondingly provided with pin holes 610, 620 or bolt installation holes.

[0146] 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 connecting plate 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.

[0147] 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.

[0148] 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.

[0149] A further solution is, Figure 6 and Figure 7 As shown, the stovetop-less cooker of the present invention includes a knob installation assembly 7, which mainly includes:

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by threads.

[0158] 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.

[0159] 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.

[0160] Further, such as Figure 7 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 .

[0161] like Figure 8 As shown, the installation method of the stove without a cooktop of the present invention comprises the following steps:

[0162] S1, connecting the connecting arm 11 of the connecting frame 1 to the assembly portion 30 of the stove bottom shell 3;

[0163] First, the connecting arm 11 is precisely and firmly connected to the assembly part 30 of the bottom shell of the cooker. This step requires the installer to strictly follow the design requirements and installation specifications to ensure that the connection between the connecting arm and the assembly part is tight and there is no looseness or deviation, so as to lay a solid foundation for subsequent installation operations. For example, during the connection process, it is necessary to carefully check the fit of the connection part, use appropriate tools and connection parts, and operate according to the specified torque or connection method to ensure the reliability and stability of the connection.

[0164] Before or after step S1, the internal parts of the cooker, such as the clamping assembly 6, the burner 2, the knob bracket 72, the switch valve 8, etc., are installed on the cooker bottom shell 3, ensuring that the distance between the adjustable panel and the support arm is much greater than the thickness of the table top, and preferably the adjustable panel is adjusted down to the limit position. The above operation completes the assembly of the internal structure of the cooker 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.

[0165] S2, lift up the stove bottom shell 3 under the table top 4, move the support arm 12, and retract it toward the connecting arm 11, so that the support arm 12 passes through the table top mounting hole 41 upward from the bottom of the table top 4;

[0166] In this step, carefully lift the stove bottom shell 3. At this time, you need to pay attention to keeping the stove bottom shell stable to avoid damage to components or difficulty in installation due to shaking or tilting. Fig. 9 As shown, the support arm 12 is firstly abutted against the hole wall at the lower end of the table top installation hole 41, and the reaction force of the hole wall on the support arm guide section 123 is used, which will cause the support arm 12 to overcome the elastic force of the compression spring and push the support arm 12 to move in the direction of retracting to the connecting arm 11, so that the support arm 12 can smoothly and accurately penetrate the table top installation hole 41 from the bottom of the table top 4 to the top. In this process, the installer needs to control the force and angle to ensure that the support arm can accurately align with the table top installation hole.

[0167] S3 , after the support arm 12 passes through the table top installation hole 41 , it moves in the reverse direction and extends out from the connecting arm 11 , thereby being supported on the periphery of the table top installation hole 41 , and the stove bottom shell 3 is suspended below the table top 4 .

[0168] When the support arm 12 passes through the table mounting hole 41 as a whole, the force exerted by the hole wall on the support arm 12 disappears, and the support arm 12 moves in the extending direction due to the elastic force of the compression spring to restore the initial state. At this time, the support arm 12 is supported on the outer periphery of the table mounting hole 41 to realize the hoisting of the stove bottom shell 3 (see Fig. 9 ).

[0169] After step S3, the clamping assembly 6 is adjusted, and the height of the adjustable panel 61 is adjusted upwards so that it fits against the lower surface of the tabletop 4, and the cooker bottom shell 3 is initially fixed by cooperating with the support arm 12. This step can further enhance the stability of the cooker bottom shell installation, reduce the possibility of shaking, ensure the firmness and safety of the entire cooker without a cooktop after installation, and lay a good foundation for subsequent fine debugging and use.

[0170] 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 Fig.10 and Fig.11 ).
