Description

TECHNICAL FIELD

[0001] The utility model relates to gas -cooker technical field especially a kind of pot support and gas -cooker. BACKGROUND

[0002] In prior art, gas -cooker pot support as the key component of supporting cookware, it is usually composed of metal frame and several supporting legs, and its bottom is usually equipped with rubber pad to realize anti-skid, shock absorption and certain degree of heat insulation function. However, with the development of modern kitchen appliances to high power and high temperature, especially the popularity of fierce fire stove, embedded gas stove and other equipment, pot support is exposed to high temperature environment of 180 DEG C to 250 DEG C for a long time during use. Traditional rubber pad is usually made of ordinary silicone rubber or nitrile rubber, and its temperature resistance limit is generally only 120 DEG C to 150 DEG C, which is prone to thermal aging, hardening, cracking and even melting deformation under the action of continuous high temperature. According to industry test data, the anti-skid coefficient of conventional rubber pad decreases by more than 40% after 300 times of 200 DEG C high temperature cycle test, and the volume shrinkage rate is as high as more than 15%, which not only loses basic function, but also may cause cookware to overturn due to structural failure, and there is serious safety hazard.

[0003] In addition, the existing pot support structure is mostly solid metal sheet, and no effective heat dissipation or heat insulation mechanism is provided. Heat is quickly accumulated on the supporting leg through conduction of pot bottom and radiation of flame, and is directly transmitted to the rubber pad through large-area adhesion, and the rubber pad is mostly designed as solid and non-porous, lacks internal heat dissipation channel and thermal resistance buffer layer, so that heat is continuously accumulated in the rubber pad, further aggravating material degradation. UTILITY MODEL CONTENTS

[0004] In view of the above problems, the utility model provides a pot support with efficient heat insulation and reliable heat dissipation, and a gas -cooker provided with the pot support.

[0005] The utility model provides a pot support in the first aspect, including frame and multiple supporting legs. The multiple supporting legs are vertically arranged and uniformly distributed and fixedly connected to the frame. The middle part of the supporting leg is provided with a hollow hole penetrating through the thickness of the supporting leg.

[0006] Further, it further includes temperature insulation plug sheet. The temperature insulation plug sheet includes plug sheet body and clamping protrusion arranged on one side of the plug sheet body. The temperature insulation plug sheet is connected with the supporting leg through the clamping protrusion and the hollow hole.

[0007] Further, the plug sheet body is sheet-shaped and closely adheres to one side surface of the supporting leg.

[0008] Furthermore, there are multiple snap-fit ​​protrusions and multiple hollow holes, which are arranged in a one-to-one correspondence so that the heat insulation plug and the support foot are connected by multiple snap-fit ​​points. The perforated holes are arranged in multiple columns, with the perforated holes in adjacent columns being staggered.

[0009] Furthermore, the insulating plug is made of a high thermal conductivity material or a high thermal resistance composite material.

[0010] Furthermore, the bottom of the support leg is provided with a rubber pad, which includes a horizontally arranged bottom wall and a first side wall and a second side wall respectively vertically arranged on opposite sides of the bottom wall. The bottom ends of the first side wall and the second side wall are fixedly connected to the two sides of the bottom wall respectively. The support leg is plate-shaped, and the first sidewall, the bottom wall, and the second sidewall wrap around the bottom end and both sides of the support leg.

[0011] Furthermore, the bottom end of the support leg is provided with a snap-fit ​​part; The inner surface of the bottom wall is provided with a locking part; The rubber pad is connected to the support leg by means of a snap-fit ​​part and a snap-fit ​​part.

[0012] Furthermore, the rubber pad is provided with at least one heat dissipation hole.

[0013] Furthermore, the side of the support leg is provided with a frame connecting groove; the frame connecting groove is adapted to and connected to the frame of the pot support.

[0014] The second aspect of this utility model provides a gas stove, including a pot support as described in the above technical solution.

[0015] This utility model has the following advantages or beneficial effects: The pot support effectively breaks the continuous heat conduction path of traditional solid metal feet by setting a perforated hole through the thickness of the foot, which significantly improves the efficiency of heat convection and radiation dissipation. This avoids the continuous accumulation of flame radiation heat and pot bottom conduction heat inside the foot, thereby greatly reducing the overall temperature of the foot. At the same time, it provides a basic guarantee for the integration of subsequent heat insulation components and the long-term stable operation of the rubber gasket, fundamentally alleviating the safety hazards of rubber gasket aging, deformation or even failure caused by high temperature.

[0022] Example 1 like Figures 1 to 6 As shown, this utility model relates to a pot support, including a ring-shaped or square frame 7 and multiple support legs 1. The multiple support legs 1 are vertically arranged and evenly distributed along the circumference of the frame 7, and are firmly connected to the frame by welding, riveting, or other methods, thus forming a stable overall structure. Each support leg 1 has a certain height in the vertical direction to ensure a reasonable gap between the bottom of the pot and the burner holes of the stove after placement, ensuring combustion efficiency and heat conduction. Crucially, each support leg 1 has a perforated hole 5 extending through its thickness in the central area. The perforated hole 5 can be circular, elliptical, rectangular, or polygonal, preferably arranged in a strip or honeycomb pattern to maximize the perforated area while ensuring structural strength. The function of the perforated hole 5 is to break the continuous heat conduction path of the traditional solid metal support leg 1, allowing the radiant heat from the flame and the heat conducted through the pot bottom to dissipate quickly from the perforated area through air convection and thermal radiation, effectively reducing the overall temperature of the support leg and preventing the continuous accumulation of heat inside the metal. In addition, the perforated holes 5 can reduce the overall weight, improve the product's aesthetics, and enhance its resistance to heat deformation to a certain extent.

[0023] The support leg 1 itself is a sheet structure, that is, its size in the width direction is much larger than that in the thickness direction, so it has two large main side surfaces (which can be called one side and the other side) and two small end surfaces (which can be called one end and the other end).

[0024] Based on the aforementioned pot support, a heat-insulating plug 3 is further added. This heat-insulating plug 3 consists of two parts: a plug body 32 and a snap-fit ​​protrusion 31. The plug body 32 is a thin sheet structure with a certain thickness and planar dimensions, typically made of a high thermal conductivity material (such as high thermal conductivity ceramic) or a high thermal resistance composite material (such as ceramic fiber reinforced resin). The snap-fit ​​protrusion 31 is located on one side surface of the plug body 32, and its shape and size match the perforated hole 5 on the support leg 1. During assembly, the snap-fit ​​protrusion 31 of the heat-insulating plug 3 is aligned with the perforated hole 5 on the support leg 1, and appropriate pressure is applied to make it embed and achieve an interference fit, thereby firmly connecting the heat-insulating plug 3 to the support leg 1. This connection method eliminates the need for additional adhesives or fasteners, facilitates disassembly and replacement, and avoids the risk of adhesive failure at high temperatures. By utilizing the high thermal conductivity of the insulating plug 3, the temperature of the foot 1 is reduced, or its high thermal resistance slows down the rate of heat conduction from the foot metal to the downward rubber pad, thereby significantly reducing the actual temperature borne by the rubber pad.

[0025] The heat-insulating plug body 32 is designed as a sheet-like structure, with its outline conforming to a portion of the surface of the support leg 1. After installation, the plug body 32 is tightly attached to one outer surface of the support leg 1, ensuring no noticeable gap between them. This fitting design not only enhances the overall structural integrity, preventing the heat-insulating plug 3 from shifting or falling off during use, but more importantly, it forms a continuous heat-insulating layer, maximally blocking the heat conduction path from the metal of the support leg 1 to adjacent areas (especially the rubber pad mounting position). The thickness of the plug body 3 is precisely calculated to meet the heat insulation requirements without excessively increasing the thickness of the support leg 1, which would affect the stability or aesthetics of the cookware. In some embodiments, the surface of the plug body 32 may also be micro-textured or coated with a low-emissivity coating to further suppress heat radiation transfer.

[0026] To improve the reliability of the connection and the uniformity of heat insulation between the heat-insulating plug 3 and the support leg 1, this invention adopts a multi-point snap-fit ​​structure. Specifically, multiple perforated holes 5 are provided on a single support leg 1, and correspondingly, multiple snap-fit ​​protrusions 31 of the same number and corresponding positions are provided on the heat-insulating plug 3. These perforated holes 5 are not simply arranged linearly, but are distributed in multiple columns according to a specific pattern. For example, two or three columns of perforated holes 5 are provided in the height direction of the support leg 1, with each column containing two or more perforated holes 5; more preferably, the perforated holes 5 in adjacent columns are arranged in an alternating manner, that is, the holes in the upper column are located directly above or directly below the two holes in the lower column. This alternating layout not only improves the heat dissipation efficiency of the perforated holes 5 (forming a more complex airflow channel), but also allows the heat-insulating plug 3 to be connected to the support leg 1 through multiple snap-fit ​​points that are not on the same vertical or horizontal line, greatly enhancing the resistance to torsion, shearing, and vibration, and effectively preventing the heat-insulating plug 3 from loosening, shifting, or even falling off during long-term use or frequent placement / removal of cookware. The multi-point snap-fit ​​structure also makes the heat insulation effect more uniform throughout the height range of the entire support leg 1, avoiding the formation of local hot spots, thus providing more comprehensive thermal protection for the rubber pad 2 below.

[0027] The pot support also has rubber pads 2 installed at the bottom of each support leg 1. These rubber pads 2 are typically made of elastic polymer materials, such as modified silicone rubber, fluororubber, or special rubber with added high-temperature resistant fillers (such as silica, alumina, or ceramic powder), to balance anti-slip properties and cushioning. Their main functions include: preventing the pot support from sliding, absorbing the impact of placing the pot, reducing vibration noise during cooking, and most importantly—acting as a final heat insulation barrier to prevent residual heat from the support leg 1 from being directly conducted to the stove surface. However, traditional rubber pads 2 are prone to aging and failure due to long-term exposure to high temperatures. Therefore, this invention, through the aforementioned hollow design of the support leg 1 and the heat insulation of the heat-insulating plug 3, significantly reduces the heat transferred to the bottom of the support leg 1, making the actual working temperature of the rubber pad 2 far below its material's temperature resistance limit.

[0028] The specific structure of the rubber pad 2 is designed to have a horizontally arranged bottom wall 21, and a first side wall 22 and a second side wall 23 extending upward from opposite sides of the bottom wall 21. Both the first side wall 22 and the second side wall 23 are vertical, and their bottom ends are fixedly connected to the left and right edges of the bottom wall 21, thus forming a U-shaped overall structure. The U-shaped rubber pad 2 precisely wraps around the bottom end and two sides of the support leg 1, so that the rubber pad 2 not only covers the lower surface of the support leg 1, but also covers its left and right sides, effectively reducing the direct heat exchange path between the metal support leg 1 and the gas stove surface, while enhancing the adhesion stability of the rubber pad 2 on the support leg 1, preventing it from falling off or shifting during the placement or movement of cookware.

[0029] To further ensure the reliability of the connection between the rubber pad 2 and the support leg 1, a locking part 4 is provided at the bottom end of the support leg 1. This locking part 4 can be a groove, a through hole, or an elastic clamping cavity. Correspondingly, a matching engaging part 24, such as a protrusion, a column, or a locally thickened structure, is provided on the inner surface of the bottom wall 21 of the rubber pad 2 (i.e., the side that contacts the bottom end of the support leg 1). When the rubber pad 2 is fitted onto the bottom end of the support leg 1, the locking part 4 engages with the engaging part 24, forming a mechanical interlock, thereby firmly connecting the rubber pad 2 to the support leg 1 and preventing the rubber pad 2 from loosening due to softening at high temperatures or external impact. This locking structure eliminates the need for adhesives, facilitating assembly and replacement, and also avoids the risk of adhesive aging and failure at high temperatures.

[0030] Furthermore, considering that the rubber pad 2 is prone to internal heat accumulation under long-term high-temperature environments, this invention also provides at least one heat dissipation hole 25 on the rubber pad 2. These heat dissipation holes 25 can be circular, elliptical, or polygonal through holes penetrating the bottom wall 21, the first side wall 22, and the second side wall 23 of the rubber pad 2, and are evenly distributed on the rubber pad 2. The presence of the heat dissipation holes 25 accelerates the dissipation of heat from the inside of the rubber pad 2 to the external environment; moreover, the porous structure itself forms an additional thermal resistance layer, reducing the overall thermal conductivity of the rubber pad 2, thereby effectively controlling the internal temperature of the rubber pad 2 and preventing it from exceeding the material's temperature resistance limit and melting, cracking, or releasing harmful substances.

[0031] Furthermore, to integrate the support leg into the complete pot support system, one end of the support leg 1 (i.e., one of the smaller side panels) is provided with a frame connection groove 6 for connecting to the pot support frame 7. This frame connection groove 6 is typically designed as a recessed portion formed by an inward indentation at one end of the support leg 1, with its vertical height matching the height of the pot support frame 7 and its shape conforming to the local contour of the frame 7. During assembly, this recessed portion snaps into the corresponding position on the frame 7 and is permanently fixed by welding. This structure ensures both the positioning accuracy between the support leg and the frame 7 and provides sufficient connection strength, ensuring that the entire pot support maintains its structural integrity even when subjected to heavy pots or severe vibrations.

[0032] This utility model solves the safety hazard caused by the failure of the rubber pad 2 of the traditional pot support due to high temperature through the coordinated structural design of the support leg 1, the rubber pad 2 and the heat insulation plug 3, and has outstanding practicality and market application value.
