Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, specifically a gas valve for a concealed gas stove. Background Technology

[0002] As an indispensable cooking appliance in modern kitchens, the safety and stability of gas stoves are of paramount importance. In the design of gas stoves, for aesthetic purposes, space-saving, and ease of cleaning, concealed or built-in installation methods are often adopted, hiding the gas connection and control components under the countertop.

[0003] Traditional concealed gas cooktop installation typically involves pre-drilling holes on the cooktop panel corresponding to the burners and gas valve knobs. During installation, the cooktop body must be passed through these pre-drilled holes from bottom to top before being secured. The gas valve, as a key component controlling gas flow, is crucial, and its installation stability directly affects the overall performance, lifespan, and operational safety of the cooktop.

[0004] In existing technology, to achieve a suspended installation of a gas valve below a control panel, an upward-extending guide tube is typically installed on the gas valve body. This guide tube serves both to support and position the valve body. The guide tube passes through a knob mounting hole on the control panel, and a nut is fitted onto the outside of the guide tube. By tightening the nut, the gas valve body is connected to the control panel, thus suspending it below the control panel. The gas valve knob is installed on the portion of the guide tube that protrudes from the control panel.

[0005] However, the above-mentioned existing technical solutions have the following significant drawbacks:

[0006] Firstly, the guide tube on a conventional gas valve body is typically relatively small, and its design often places it close to the valve stem opening to allow space for the valve stem. This structure results in a thinner tube wall and limited overall load-bearing capacity. During long-term use of the gas stove, especially when the user frequently operates the knob or the knob is accidentally impacted, the guide tube is prone to plastic deformation, fatigue, or even breakage due to stress concentration. Damage to the guide tube will directly cause the gas valve body to lose its stable support, or even detach from the panel, seriously affecting the normal function and safety of the stove.

[0007] Secondly, while the existing technology of fixing the guide tube to the panel by tightening nuts provides a certain degree of stability in the initial stage of installation, the nuts are prone to loosening due to environmental factors such as vibration and thermal expansion and contraction during long-term use of the gas stove. Once the nuts loosen, the suspended installation of the gas valve body will be unstable, and the valve body may wobble, affecting not only the operation but also potentially causing loosening or leakage at the internal gas pipeline connections, posing a gas safety hazard. Moreover, during installation, unevenness between the guide tube and other components can cause friction between them when tightening the nuts, which may ultimately damage the stove, increase the user's maintenance costs, and even threaten the user's personal safety and property. Therefore, further improvements are necessary. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a concealed gas valve for gas stoves that is more compact in structure, more aesthetically pleasing in appearance, easy to install, and has a stable and reliable connection.

[0009] The purpose of this utility model is achieved through the following method: a concealed gas valve for a gas stove, comprising a valve body, a valve core disposed inside the valve body, the valve core being connected to an inlet pipe and an outlet pipe, the valve core being connected to a valve stem, a connecting post extending upward from the valve body, the connecting post being hollow inside, the valve stem passing through the valve body and the connecting post and connecting to a knob, a valve cover being installed on the top of the connecting post, the valve cover covering the mounting hole on the panel, and the valve body being suspended and installed on the panel using the valve cover and the connecting post.

[0010] Furthermore, a guide hole is provided at the center of the valve cover, and the valve stem extends upward through the guide hole to connect with the knob. The knob is covered and installed on the top of the valve cover.

[0011] Furthermore, the valve cover is provided with several threaded holes, and the fixing bolts pass through the threaded holes to connect with the connecting column, thereby installing the valve cover and the connecting column as one unit.

[0012] The valve cover has a sealing ring extending upward from the top, the screw hole is located inside the sealing ring, and the bottom of the knob is fitted onto the outside of the sealing ring.

[0013] The bottom of the valve cover extends upward to form a docking ring, and the top of the connecting post is fitted inside the docking ring.

[0014] The connecting column is integrally formed with the valve body.

[0015] The connecting column and valve body are manufactured separately, but are connected as one unit by bolts.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0017] Instead of the small-volume guide tubes found in existing technologies, a connecting post extends upwards from the valve body. This connecting post is relatively large, significantly increasing its contact area with the valve body. This large volume and large contact area design makes the connection between the connecting post and the valve body more robust.

[0018] The connection point or connection hole of the connecting column of this invention is offset from the valve core, avoiding the weak points caused by the valve core and its connecting structure. This offset design makes the joint between the connecting column and the valve body less susceptible to the influence of the internal working space of the valve core, resulting in higher structural integrity and more uniform stress distribution. This significantly enhances its fatigue and impact resistance, effectively preventing the connecting column from breaking during long-term use or under external impact, and greatly improving the reliability and service life of the gas valve.

[0019] This invention employs a valve cover that covers the mounting holes on the panel, and the valve body is suspended on the panel via the valve cover and connecting post. This design allows the valve cover to serve as the primary panel contact and fixing component. This robust fixing method effectively reduces installation loosening problems caused by vibration, thermal expansion and contraction, etc., ensuring that the gas valve body is always securely suspended below the panel, thus improving the overall reliability and safety of the product.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A concealed gas valve for a gas stove includes a valve body 1, a valve core 2 disposed inside the valve body 1, the valve core 2 being connected to an inlet pipe and an outlet pipe, the valve core 2 being connected to a valve stem 3, a connecting post 4 extending upward from the valve body 1, the connecting post 4 being hollow inside, the valve stem 3 passing through the valve body 1 and the connecting post 4 and connecting to a knob 5, a valve cover 6 being installed on the top of the connecting post 4, the valve cover 6 covering the mounting hole 71 of the panel 7, and the valve body 1 being suspended and installed on the panel 7 by means of the valve cover 6 and the connecting post 4.

[0026] In this embodiment: a hollow connecting post 4 is provided above the valve body 1, allowing the valve stem 3 to pass through and extend upwards. During installation, the pre-drilled mounting hole 71 in the cabinet panel receives the valve cover 6, which is then connected to the top of the connecting post 4. In this way, the valve cover 6, acting as the main support and positioning component, securely suspends the valve body 1 and all its internal components below the cabinet panel. The knob 5 is connected to the valve stem 3 extending above the panel for user operation.

[0027] Compared to the small and easily broken guide tubes in the prior art, the connecting column 4 used in this utility model is larger in volume, significantly increasing the contact area with the valve body 1. Furthermore, its load-bearing capacity is mainly provided by the overall structural strength of the connecting column 4, rather than relying solely on the weak pipe wall, thereby greatly improving the suspension installation stability and load-bearing capacity of the gas valve body.

[0028] Meanwhile, the valve cover 6 and the panel 7 are combined, and the valve cover 6 and the connecting column 4 are connected, so that the valve body is stably suspended, effectively avoiding the problem of unstable installation caused by loose nuts in the prior art.

[0029] In addition, the valve body 1 and most of the connecting structures are hidden under the panel 7, with only the knob 5 and the upper part of the valve cover 6 exposed, which meets the requirements of modern gas stoves for aesthetics and easy cleaning.

[0030] In one embodiment: a guide hole 61 is provided at the center of the valve cover 6, and the valve stem 3 extends upward through the guide hole 61 and connects to the knob 5. The knob 5 is covered and installed on the top of the valve cover 6.

[0031] In this embodiment: After passing through the connecting post 4, the valve stem 3 continues upward and needs to pass through the valve cover 6 to connect with the knob 5. To ensure smooth and stable movement or rotation of the valve stem 3, a guide hole 61 is provided at the center of the valve cover 6. This guide hole 61 plays a precise guiding and positioning role for the valve stem 3. Finally, the knob 5 is installed from above, covering the top of the valve cover 6, which not only realizes the control of the valve stem 3, but also maintains the overall aesthetics.

[0032] It should be noted that the guide hole 61 ensures that the valve stem 3 remains centered during operation, reducing friction and wobbling between the valve stem and surrounding structures, making the operation of the knob 5 more stable and smooth. At the same time, the knob 5 is mounted on top of the valve cover 6, forming a complete operating interface that conceals the internal connection structure and enhances the overall visual appeal of the product.

[0033] In one embodiment, the valve cover 6 has several threaded holes 62, and fixing bolts 63 pass through the threaded holes 62 to connect with the connecting post 4, thus installing the valve cover 6 and the connecting post 4 as a whole. Through the above connection method, the valve cover 6 and the connecting post 4 are tightly combined into a whole, ensuring the suspension stability and reliability of the valve body on the panel.

[0034] In one embodiment: the valve cover 6 has a sealing ring 64 extending upward from the top, the screw hole 62 is disposed inside the sealing ring 64, and the bottom of the knob 5 is fitted onto the sealing ring 64.

[0035] In this embodiment: a sealing ring 64 extends upward from the top of the valve cover 6, surrounding the location of the threaded hole 62. Thus, the threaded hole 62 and the fixing bolt 63 are cleverly concealed inside the sealing ring 64. When the knob 5 is installed, its bottom structure fits over the outer side of the sealing ring 64. This design protects the bolted connection and ensures a tighter fit between the knob and the valve cover.

[0036] Meanwhile, the sealing ring 64 encloses the bolt hole 62 and the bolt inside, effectively preventing dust, liquid, oil and other impurities from entering the bolt hole area, extending the service life of the bolt, and preventing loosening or corrosion caused by dirt accumulation.

[0037] In addition, the bolts are hidden, making the top of the valve cover 6 look cleaner and smoother, improving the overall texture and aesthetics of the product.

[0038] Furthermore, the bottom of knob 5 is fitted onto the sealing ring 64, which further positions and supports knob 5, reducing knob wobble during operation and improving the operating feel. At the same time, it limits the radial displacement of the knob, preventing the valve stem from bending and protecting the valve body's safety during use.

[0039] In one embodiment: the bottom of the valve cover 6 extends upward to provide a docking ring 65, and the top of the connecting post 4 is fitted inside the docking ring 65.

[0040] During installation, the top structure of the connecting column 4 is directly fitted into the inside of the mating ring 65, and through a tight fit, the valve cover 6 and the connecting column 4 are concentrically connected.

[0041] The fitting structure disperses the load through the contact surface, effectively resisting lateral forces and providing stable suspension support for the valve body.

[0042] In one embodiment, the connecting column 4 is integrally formed with the valve body 1. This integral forming eliminates weaknesses at the connection point, maximizing the bonding strength between the connecting column 4 and the valve body 1, making it less prone to breakage or deformation. Simultaneously, it eliminates the need for additional connectors, simplifying material management and assembly processes.

[0043] In one embodiment: the connecting column 4 and the valve body 1 are manufactured separately, but are connected as one unit by bolts.

[0044] In this implementation, the connecting column 4 and the valve body 1 are manufactured as two separate components. In the subsequent assembly process, these two components are securely connected together by bolts to form a functional unit.

[0045] This design allows the connecting column 4 and the valve body 1 to be made of different materials, such as a corrosion-resistant copper alloy for the valve body 1 and high-strength steel or special plastic for the connecting column, thereby optimizing their respective performance and cost.

[0046] Meanwhile, the complex valve body 1 and connecting column 4 can be precision machined independently, simplifying their respective manufacturing difficulties. Furthermore, their function can be achieved by adding a connecting column without altering the existing valve body, which facilitates modular design and production, improving production efficiency and management convenience.

[0047] In summary, this utility model provides an innovative concealed gas valve for gas stoves. Its core working principle lies in using a robust and reliable suspension installation system to firmly fix the gas valve body to the bottom of the cabinet panel.

[0048] Specifically, a large-volume, high-strength connecting post 4 extends upward from the valve body 1 of the gas valve. This connecting post 4 is hollow, and the valve stem 3 passes upward from the valve core 2 inside the valve body 1 through the connecting post 4, ultimately connecting to the knob 5 above the panel. Compared to the thin guide tubes of existing technologies, the connecting post 4 has a larger contact area with the valve body 1, and the connection point or connection hole is offset from the valve core, significantly improving its structural strength and load-bearing capacity, effectively avoiding the problem of easy breakage of traditional guide tubes.

[0049] Furthermore, the valve cover 6 is designed to cover the mounting hole 71 on the cabinet panel 7. The lower part of the valve cover 6 is tightly connected to the top of the connecting post 4. By fixing the valve cover 6 to the panel, the entire gas valve body 1 and its auxiliary components, valve core, inlet and outlet gas pipes, etc., are reliably suspended below the panel 7. This top-down suspension method, combined with the robust design of the connecting post 4, ensures the high stability and safety of the gas valve during long-term use, avoiding the problems caused by loose nuts in traditional installation methods.

[0050] Furthermore, the valve stem 3 passes through the guide hole 61 on the valve cover 6, ensuring smooth and precise movement of the valve stem and providing a good tactile feel for the knob 5. The knob 5 is mounted on top of the valve cover 6, making the entire control interface neat and aesthetically pleasing, in line with the design concept of a concealed cooktop.

[0051] It should be noted that, in the connection between the valve cover 6 and the connecting column 4, this utility model provides two parallel and reliable solutions: bolt connection or sleeve connection. The bolt connection can be further protected and made more aesthetically pleasing by using the sealing ring 64.

[0052] In the manufacturing of the connecting column 4 and the valve body 1, this utility model provides two parallel solutions: integral molding or separate manufacturing followed by bolt connection. These diverse implementation methods not only ensure the strength of the connection but also provide great flexibility in production to adapt to different material, process, and cost requirements.

[0053] This utility model, through innovation in the main structure and installation method of the gas valve, provides a concealed gas valve for gas stoves that is high-strength, highly stable, easy to operate, and aesthetically pleasing. It fundamentally overcomes the defects of existing gas valve suspension installation structures, such as weak load-bearing capacity, easy breakage, and easy loosening, significantly improving the reliability, service life, and safety of gas stove products. Therefore, it can be widely promoted and used.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
