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 connecting frame for a stove without a cooktop. The structure shrinks its volume by rotating the supporting arm downward to move it closer to the connecting arm so that it can pass through the tabletop installation hole smoothly, and then rotates the supporting arm upward to open 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 support arm is used for supporting on the table top. The support arm is rotatably connected to the connecting arm and can rotate up and down within a certain rotation angle relative to 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 relatively upward and downward rotatable manner, and this connection method gives the supporting arm a certain free rotation angle. By using this free rotation angle, the supporting arm is moved closer to the connecting arm direction to smoothly pass through the table top installation hole from under the table top, and then an effective support is formed above the table top, 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 rotates downward and moves toward the connecting arm, so that it can extend upward from the bottom of the table into the table installation hole;

[0022] In the second state, the support arm rotates upward until it reaches the maximum angle with the connecting arm, so as to support the outer periphery of the table top mounting hole;

[0023] Preferably, the maximum angle α of the support arm when it rotates relative to the connecting arm to the second state is in the range of 75°-105°, preferably α is in the range of 85°-95°, and optimally 90°.

[0024] In the first state, the support arm rotates downward and approaches the connecting arm, so that it can smoothly extend into the table top mounting hole from under the table top, providing possibility for the subsequent installation action of the support arm passing through the table top mounting hole.

[0025] In the second state, the support arm passes through the countertop mounting hole. As the support arm rotates upward and opens to the maximum angle, it can be supported on the peripheral area of ​​the countertop mounting hole. In this way, reliable support and stability are provided for the connecting frame of the entire cooktopless stove, ensuring that the stove can remain stable during use without shaking, displacement or other adverse conditions.

[0026] 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;

[0027] Preferably, the elastic member is a torsion spring structure, and the torsion arms at both ends of the torsion spring respectively abut against two side surfaces of the support arm and the connecting arm that are arranged opposite to each other in a one-to-one correspondence.

[0028] The above structure makes the process of switching the support arm from the first state to the second state smoother and more convenient to a certain extent, and reduces problems such as jamming or wear that may be caused by switching of the rigid mechanical structure.

[0029] A further solution is that the connecting arm is provided with a limiting structure for limiting the maximum angle of the support arm when it is opened in the second state;

[0030] Preferably, the limiting structure protrudes toward one side of the connecting arm and is located above the supporting arm;

[0031] Preferably, the upper end of the connecting arm is connected to one end of the supporting arm via a rotating shaft, and the limiting structure extends laterally from the upper end of the connecting arm toward the upper side of the supporting arm to prevent the supporting arm from further rotating upward;

[0032] Preferably, the limiting structure includes a connecting member and a blocking member, the connecting member is arranged along the vertical extension direction of the connecting arm, and is fixedly connected to the opposite side of the connecting arm relative to the supporting arm, and the blocking member is horizontally arranged at the upper end of the connecting arm, one end of which is connected to the upper end of the connecting member, and the other end of which extends toward the upper side of the supporting arm;

[0033] Preferably, the connecting member and the blocking member are an integrally bent L-shaped structure.

[0034] The limiting structure of the present invention can effectively prevent the support arm from continuing to rotate upward, thereby determining the maximum angle at which the support arm can be opened relative to the connecting arm, providing strong guarantees for the stable support of the support arm on the peripheral area of ​​the table mounting hole, making the structural design of the connecting frame more reasonable and stable, and thereby improving the overall connection performance and assembly effect.

[0035] A further solution is that the connecting arm includes

[0036] A fixed section, used for fixed connection with the bottom shell of the cooker;

[0037] An articulated section, one end of which is connected to the fixed section and the other end of which is rotatably connected to the support arm;

[0038] Preferably, an angle β is formed between the fixed section and the hinged section, β is 70°-110°, preferably β is 80°-100°, and more preferably, β is 85°-95°;

[0039] Preferably, the connecting arm is a sheet metal part that is integrally bent to form a fixed section and a hinged section, and the sheet metal part is bent upward and extended from one end of the fixed section to form the hinged section;

[0040] Preferably, the top end of the hinged section is cut, bent, pressed and rolled to form the first axial hole.

[0041] The connecting arm of the present invention is rotatably connected to the supporting arm at the upper end of the hinge section, so that the supporting arm can rotate up and down around the top end of the hinge section within the range allowed by the limiting structure, thereby realizing the switching of different states of the supporting arm and meeting various requirements of installation and use.

[0042] In terms of structural optimization, a specific angle β is formed between the fixed section and the hinged section. The value range of the angle β is 70°-110°, more preferably 80°-100°, and more preferably, β is 85°-95°, and the most ideal situation is that β is 90°. This angle range can provide relatively balanced performance in many aspects such as mechanical conduction, structural compactness, and reasonable spatial layout.

[0043] From the manufacturing process point of view, the connecting arm adopts the method of bending sheet metal into a fixed section and a hinged section. This one-piece molding process helps to improve the overall structural strength and stability of the bracket. In addition, the top of the hinged section is processed by cutting, bending, pressing and rolling to form an axial hole, which is used for articulation with the support arm to ensure that the connection between the two is reliable and flexible, effectively improving the assembly accuracy and durability of the entire connecting frame.

[0044] The support arm is a plate-like structure, one end of which has a second shaft hole, and the other end rotates up and down around the end having the second shaft hole;

[0045] Preferably, the other end of the support arm relative to the second axial hole is arc-shaped; this arc-shaped design can reduce the contact area between the support arm and the wall of the table mounting hole, which helps the support arm to pass through the table mounting hole more smoothly;

[0046] Preferably, the support arm is a semicircular sheet metal part, and one side corresponding to the straight edge is cut, bent, pressed and rolled to form the second shaft hole.

[0047] The support arm and connecting arm of the connecting frame of the present invention are both formed by sheet metal processing, and then the two are hinged by a rotating shaft, which ensures that the two have sufficient strength and rigidity. At the same time, the rotation characteristics of the support arm relative to the connecting arm can be utilized, so that the support arm can be close to the connecting arm through the table mounting hole, and then opened and supported above the table.

[0048] 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.

[0049] A further solution is that the stove bottom shell is provided with at least two assembly parts;

[0050] 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.

[0051] 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.

[0052] Preferably, the assembly portion is arranged on a fixing frame, and the fixing frame is fixedly connected to the bottom shell of the cooker.

[0053] Further preferably, the furnace head and the corresponding assembly portion arranged on the outer side thereof are installed on the same fixing frame.

[0054] More preferably, the number of the fixing frames corresponds one to one with the number of the furnace heads.

[0055] 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;

[0056] Preferably, the clamping assembly comprises,

[0057] 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;

[0058] 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.

[0059] 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.

[0060] Further, the adjusting component includes,

[0061] a support frame connected to the adjustable panel;

[0062] 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;

[0063] 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 vertical distance between the bottom wall and the bottom shell of the stove is adjustable;

[0064] 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;

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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:

[0069] a knob mounting sleeve, at least partially adapted to be supported above a countertop;

[0070] The knob bracket is at least partially arranged under the table and fixedly connected to the bottom shell of the stove;

[0071] The knob mounting sleeve is detachably connected to the knob bracket;

[0072] Preferably, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0073] 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;

[0074] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0075] 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.

[0076] The present invention also provides a method for installing a stove without a cooktop, comprising the following steps:

[0077] S1, connecting the connecting arm of the connecting frame to the assembly part of the bottom shell of the stove;

[0078] S2, lift up the bottom shell of the stove under the countertop, and a support arm of the connecting frame abuts against the hole wall at the lower end of the countertop mounting hole to rotate the support arm downward and close it toward the connecting arm, so that the support arm passes through the countertop mounting hole upward from the bottom of the countertop;

[0079] S3. After the support arm passes through the countertop mounting hole, it rotates upward and is supported on the outer periphery of the countertop mounting hole to suspend the bottom shell of the cooker under the countertop.

[0080] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0081] 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.

[0082] The connecting frame adopts a hinged design and state switching in which the support arm can rotate up and down relative to the connecting arm: the support arm moves closer to the connecting arm to extend into the countertop mounting hole, and opens relative to the connecting arm to support the outer periphery of the countertop mounting hole, making the installation of the stove bottom shell stable and reliable, effectively solving the problem of falling off due to shaking, and ensuring safe use.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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; 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 rotated downward to enter the table top installation hole, and then rotated upward in the opposite direction after passing through the table top installation hole. The connecting arm is opened 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 installer to quickly master and implement it.

[0088] 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

[0100] 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

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] The connecting frame 1 of the present invention is 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 the bottom of the countertop 4 to support the countertop 4. The supporting arm 12 and the connecting arm 11 are connected in a manner that can rotate up and down relatively. The supporting arm 12 can rotate around the rotating axis 14 relative to the connecting arm 11 within a predetermined angle range, so that the supporting arm 12 rotates downward to approach the connecting arm 11 and then passes through the countertop mounting hole 41, and then opens by rotating upward in the opposite direction, and is stably supported on the countertop 4 at the periphery of the countertop mounting hole 41, thereby achieving the purpose of suspending the stove bottom shell 3 below the countertop 4.

[0106] The support arm 12 presents at least two different states relative to the connecting arm 11: one is the first state, in this state, the support arm 12 moves closer to the connecting arm 11 due to its own downward rotation action, thereby 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 rotates upward and opens relative to the connecting arm 11, and can be firmly supported on the countertop outside the countertop mounting hole 41. Through this ingenious design method, a solid and reliable supporting force and stability guarantee are provided for the connecting frame of the entire 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.

[0107] 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.

[0108] In a preferred design, the elastic member 13 adopts a torsion spring structure. When the support arm 12 is in the first state, the torsion arms at both ends of the torsion spring respectively contact with the two side surfaces of the support arm 12 and the connecting arm 11 that are arranged opposite to each other. Figure 2 As shown, one torsion arm 131 of the torsion spring abuts against the side of the connecting arm 11 relative to the support arm 12, and the other torsion arm abuts against the lower surface of the support arm 12 (not shown in the figure). Preferably, a groove is provided on the lower surface of the support arm 12, and the torsion arm is assembled in the groove to avoid affecting the stability of the support arm supported on the table due to its protrusion from the lower surface of the support arm 12.

[0109] Preferably, the maximum angle α of the support arm 12 when it rotates relative to the connecting arm 11 to the second state is in the range of 75°-105°, preferably in the range of 85°-95°, and optimally 90° (see Figure 2 ).

[0110] The above design enables the torsion spring to assist the support arm 12 in smoothly switching from the first state in which the support arm 12 is close to the connecting arm 11 and extends into the countertop mounting hole 41, to the second state in which the support arm 12 is open relative to the connecting arm 11 and supported on the countertop 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 stove installation structure without a cooktop, and to a certain extent makes the operation process smoother and more convenient, reducing problems such as jamming or wear that may be caused by switching of rigid mechanical structures.

[0111] In another embodiment, the connecting frame 1 of the present invention may also eliminate the design of the elastic member 13 , and the support arm 12 can be manually controlled by the installer to rotate in the opposite direction relative to the connecting arm 11 .

[0112] Furthermore, a limiting structure 15 is provided on the connecting arm 11 for limiting the maximum angle that the supporting arm 12 can open when it is in the second state. Through this limitation, it can effectively ensure that the entire structure maintains good stability and rationality under the corresponding working state, so that it can operate normally according to the established design requirements.

[0113] The limiting structure 15 is convex toward one side of the connecting arm and is located above the supporting arm 12, which can effectively limit the rotation angle of the supporting arm 12, ensure the coordinated cooperation of the connecting arm 11, the supporting arm 12 and the limiting structure 15 in spatial position, and complement the overall connecting frame structure layout.

[0114] Specifically, the upper end of the connecting arm 11 and one end of the supporting arm 12 are firmly connected by means of the rotating shaft 14. On this basis, the limiting structure 15 starts from the upper end of the connecting arm 11 and extends horizontally toward the upper side of the supporting arm 12. This extension method enables the limiting structure to accurately and effectively block the upward rotation of the supporting arm to prevent it from exceeding the predetermined maximum angle range.

[0115] Furthermore, the limiting structure 15 is specifically composed of two important parts, namely, a connecting member 151 and a blocking member 152. The connecting member 151 is arranged in an orderly manner along the direction in which the connecting arm 11 extends upward and downward, and is firmly fixedly connected to the opposite side of the connecting arm 11 relative to the supporting arm 12, preferably by riveting, like the "skeleton" of the entire limiting structure, providing a solid and stable basic support for it, ensuring that the limiting structure can remain stable when subjected to various external forces and normally perform its limiting function.

[0116] The blocking member 152 is placed horizontally at the upper end of the connecting arm 11, one end of which is tightly connected to the upper end of the connecting member 151 to form a stable connection relationship, while the other end extends toward the top of the support arm 12 to form an effective interference with the movement trajectory of the support arm 12, thereby limiting the rotation angle of the support arm 12. It is worth mentioning that, from the perspective of structural optimization, the connecting member 151 and the blocking member 152 are an L-shaped structure bent as one. This integrated design not only significantly enhances the structural strength of the limiting structure itself, making it more resistant to deformation, but also reduces the assembly process of parts and components in the manufacturing process, improves production efficiency, and is easier to operate during the assembly process, which helps to further improve the reliability and stability of the entire structure in practical applications, so that it can better meet the use requirements under complex working conditions.

[0117] The connecting arm 11 of the present invention is provided with 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 1 and Figure 2 As shown, the fixing section 111 is provided with a screw mounting hole 113 for screw connection. The connecting arm 11 also includes a hinged section 112, one end of which is connected to the fixing section 111, and the other end extends upward and is rotatably connected to the support arm 12, so that the support arm 12 can flexibly rotate around the hinged end of the hinged section 112 within a certain angle range, thereby achieving switching between different states to meet various needs during installation and use.

[0118] Further, such as Figure 1As shown, an angle β is formed between the fixed section 111 and the hinge section 112, and the value range of this angle is between 70° and 110°, preferably between 80° and 100°, and further refined preferably between 85° and 95°, and the best is 90°. The design of this angle range relatively reduces the distance between the hinge end and the bottom shell of the stove, and cooperates with the spatial layout of the stove parts in the bottom shell of the stove, which can show relatively balanced and excellent performance in many aspects such as mechanical conduction path planning, overall structural compactness shaping, and reasonable spatial layout construction.

[0119] The connecting arm 11 adopts the sheet metal integral bending process to shape the fixed section 111 and the hinge section 112. This integral molding process has a significant promoting effect on improving the overall structural strength and stability of the bracket. In addition, the top of the hinge section 112 undergoes a series of fine processes such as cutting, bending, pressing and rolling to form a first axial hole (not shown in the figure) for installing the rotating shaft 14. The first axial hole corresponds to the second axial hole of the support arm. The rotating shaft passes through the axial hole of the connecting arm and the axial hole of the support arm to realize the rotation connection between the connecting arm and the support arm, thereby ensuring that the connection between the two has a high degree of reliability and rotation flexibility, thereby effectively improving the accuracy level of the entire connecting frame in the assembly link and the durability performance during use.

[0120] The support arm 12 of the present invention adopts a plate-like structure design and is provided with a second axial hole (not shown in the figure) at one end. The support arm 12 can use the end with the second axial hole as the axis to realize the up and down rotation of the other end, thereby flexibly adjusting its spatial position state.

[0121] The other end of the support arm 12 relative to the second axial hole adopts an arc-shaped structure; this arc-shaped design can reduce the contact area between the support arm and the wall of the table mounting hole, which helps the support arm to pass through the table mounting hole more smoothly.

[0122] In order to enhance the supporting stability of the support arm 12 on the table 4, an anti-skid structure, such as an anti-skid pad or an anti-skid coating, is provided on one side of the support arm 12 used to support the table to prevent the support arm from slipping on the table and enhance lateral stability.

[0123] The support arm is made of semicircular sheet metal. In the specific processing technology, the required second axis hole is finally formed by cutting, bending, pressing and curling the corresponding straight edge. This production method can not only make full use of the characteristics of sheet metal materials to ensure that the support arm has sufficient strength and rigidity, but also ensure the dimensional accuracy and shape accuracy of the second axis hole through precise processing control, thus providing a reliable foundation for the rotational connection between the support arm and the connecting arm, and further optimizing the performance of the entire structure.

[0124] The support arm of the present invention is ingeniously designed to be able to move closer and closer to the connecting arm by rotating, so that the support arm can not only accurately pass through the countertop mounting hole in the closed state, but also be firmly supported on the peripheral area of ​​the countertop mounting hole after rotating and opening, thereby realizing a one-time firm suspension of the bottom shell of the stove, greatly simplifying the installation steps, improving the installation efficiency and convenience, and effectively reducing the manpower and time costs during the installation process.

[0125] 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 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 has an assembly portion 30, the main function of the assembly portion 30 is to install the above-mentioned connecting frame 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 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, the connecting arm 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 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. In the embodiment of the present invention, the assembly part 30 is preferably provided on the bottom plate 31 of the bottom shell of the stove.

[0126] 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 ).

[0127] 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 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 the left and right burners 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.

[0128] 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.

[0129] 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 installed together 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.

[0130] 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.

[0131] The clamping assembly 6 mainly includes the following components:

[0132] 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.

[0133] 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 .

[0134] 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.

[0135] A further solution is, Figure 5 As shown, the adjustment component 62 mainly includes:

[0136] 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;

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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:

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by threads.

[0153] 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.

[0154] 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.

[0155] 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 .

[0156] like Figure 8 As shown, the installation method of the stove without a cooktop of the present invention comprises the following steps:

[0157] S1, connecting the connecting arm 11 of the connecting frame 1 to the assembly portion 30 of the stove bottom shell 3;

[0158] 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.

[0159] 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.

[0160] S2, lift the stove bottom shell 3 under the countertop 4, the support arm 12 of the connecting frame 1 abuts against the hole wall at the lower end of the countertop mounting hole 41 to rotate the support arm 12 downward and close it toward the connecting arm 11, so that the support arm 12 passes through the countertop mounting hole 41 upward from the bottom of the countertop 4;

[0161] 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 mounting hole 41, and the downward reaction force of the hole wall is used to force the support arm 12 to overcome the elastic force of the torsion spring and push the support arm 12 to rotate downward, so that the support arm 12 can smoothly and accurately penetrate the table top mounting 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 mounting hole.

[0162] S3 , after the support arm 12 passes through the table top installation hole 41 , it rotates upward and opens relative to the connecting arm 11 , thereby supporting the outer periphery of the table top installation hole 41 and suspending the stove bottom shell 3 below the table top 4 .

[0163] 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 rotates upward due to the elastic force of the torsion 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 ).

[0164] 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.

[0165] 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 ).

[0166] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
