[0027] Embodiment 1

[0028] See Figures 1 to 4 As shown, this embodiment provides a pot rack, including an upper shelf 101 and a lower shelf 102. The upper shelf 101 is provided with a turned - out edge 103. Multiple notches 104 are arranged at the edge of the turned - out edge 103. The turned - out edge 103 is connected with the outer surface of the lower shelf 102 in an interference fit manner, so as to form a cavity between the upper shelf 101 and the lower shelf 102.

[0029] Based on this structure, for the pot rack provided in this embodiment, by providing a plurality of notches 104 at the edge of the outward flanging 103, when the outward flanging 103 is in interference fit connection with the outer surface of the side wall of the lower rack 102, the contact area between the outer surface of the side wall of the lower rack 102 and the outward flanging 103 is reduced, that is, the heat conduction area between the lower rack 102 and the upper rack 101 is reduced. At the same time, the cavity has the effect of blocking heat transfer, thereby reducing the heat transferred from the upper rack 101 to the lower rack 102 and the cooktop panel, effectively preventing the temperature of the cooktop panel from being too high, protecting the panel from being damaged or cracked due to high temperature, and improving safety.

[0030] During use, the pot rack may be deformed due to heat. After deformation, the upper rack 101 and the lower rack 102 may be separated. Therefore, in order to further improve the use safety, the depth of the notch 104 in this embodiment is less than the width of the outward flanging 103. In this way, it is convenient to weld the edge of the notch 104 to the outer surface of the side wall of the lower rack 102. After welding, the upper rack 101 and the lower rack 102 can be fixedly connected together, avoiding the risk of separation between the upper rack 101 and the lower rack 102.

[0031] Since only the edge of the notch 104 is welded to the outer surface of the side wall of the lower rack 102, compared with the way of welding the entire outward flanging 103 and the outer surface of the side wall of the lower rack 102, the discontinuous welding method in this embodiment can reduce the contact area between the upper rack 101 and the lower rack 102, thereby reducing the heat transferred from the upper rack 101 to the lower rack 102 and the cooktop panel, effectively preventing the temperature of the cooktop panel from being too high, protecting the cooktop panel from being damaged or cracked due to high temperature, and further improving safety.

[0032] In order to minimize the welding contact as much as possible while ensuring the welding firmness, the length L of the weld 109 where the edge of the notch 104 is welded to the outer surface of the lower rack 102 in this embodiment is not less than 10 mm.

[0033] Furthermore, the sum of the lengths of the welds 109 where the edges of the plurality of notches 104 are welded to the outer surface of the lower rack 102 is 1 / 5 to 1 / 2 of the perimeter of the outward flanging 103.

[0034] Specifically, the number of the notches 104 and the distance between two adjacent notches 104 can be selected according to the perimeter of the outward flanging 103 and the length of the weld 109.

[0035] For example, the sum of the lengths of the welds 109 where the edges of the plurality of notches 104 are welded to the outer surface of the lower rack 102 can be 1 / 4 of the perimeter of the outward flanging 103.

[0036] Optionally, the plurality of notches 104 are evenly spaced along the circumferential direction of the outward flanging 103.

[0037] Further, referring to Figure 3 as shown, a heat insulation material module 105 is disposed in the cavity, and the outer surface of the heat insulation material module 105 is attached to the inner wall of the cavity.

[0038] By disposing the heat insulation material module 105 in the cavity, the heat radiation of the flame can be effectively alleviated from being transferred from the upper shelf 101 to the lower shelf 102, thereby further reducing the temperature of the cooking appliance panel and reducing the risk of breakage and explosion of the cooking appliance panel.

[0039] The outer surface of the heat insulation material module 105 is attached to the inner wall of the cavity. In this way, it can not only prevent the heat insulation material module 105 from shaking in the inner cavity and reduce the risk of breakage due to shaking, but also play the heat insulation role of the heat insulation material module 105 and enhance the heat insulation effect.

[0040] Further, the heat insulation material module 105 mainly includes 90 - 95 parts of nano - fumed silica and 5 - 10 parts of ceramic fiber.

[0041] Specifically, a mold is made according to the specifications and shape of the cavity formed by the combination of the upper shelf 101 and the lower shelf 102. Nano - fumed silica and ceramic fiber are mixed with an appropriate amount of water and stirred evenly to form a paste - like mixture. The paste - like mixture is injected into the mold and dried naturally. After drying, the heat insulation material module 105 can be obtained.

[0042] By adding ceramic fiber, the toughness and structural strength of the heat insulation material module 105 can be enhanced to prevent the module from cracking.

[0043] Optionally, the content of nano - fumed silica can be, but is not limited to, 90 parts, 91 parts, 92 parts, 93 parts, 94 parts or 95 parts.

[0044] Optionally, the content of ceramic fiber can be, but is not limited to, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts or 10 parts.

[0045] Further, both the upper shelf 101 and the lower shelf 102 are annular. Outer flanges 103 are provided on both the outer circumferential edge and the inner circumferential edge of the upper shelf 101. The outer flange 103 located on the outer circumferential edge of the upper shelf 101 is connected with an interference fit to the outer surface of the outer ring side wall of the lower shelf 102, and the outer flange 103 located on the inner circumferential edge of the upper shelf 101 is connected with an interference fit to the outer surface of the inner ring side wall of the lower shelf 102.

[0046] Specifically, the upper shelf 101 is a concave annular disc - shaped structure, and the lower shelf 102 includes an annular bottom plate and an inner ring side wall and an outer ring side wall extending upward from the inner and outer ring edges of the annular bottom plate.

[0047] The following takes the outer ring side wall as an example for illustration. Referring toFigure 4 As shown, a narrow edge portion 106 is integrally formed at the edge of the outer ring side wall. The outwardly turned edge 103 located at the circumferential outer edge of the upper rack 101 encloses the narrow edge portion 106, and the two are connected by interference fit. Among them, the narrow edge portion 106 corresponding to the position of the notch 104 is exposed.

[0048] When welding is required, the edge of the notch 104 is welded to the outer surface of the narrow edge portion 106 to achieve firm fixation between the upper rack 101 and the lower rack 102.

[0049] It should be noted that the structure of the inner ring side wall is similar to that of the outer ring side wall. The connection method between the inner ring side wall and the outwardly turned edge 103 located at the circumferential inner edge of the upper rack 101 is the same as that between the outer ring side wall and the outwardly turned edge 103 located at the circumferential outer edge of the upper rack 101, and will not be elaborated here.

[0050] Furthermore, high-temperature resistant coatings are provided on the outer surfaces of both the upper rack 101 and the lower rack 102. In this way, it can effectively alleviate the deformation problem of the pot rack caused by heat during use.

[0051] The high-temperature resistant coating is made of non-metallic inorganic materials, mainly including components such as silicon dioxide, aluminum oxide, and calcium oxide. After forming a porcelain film, the thickness is 30 - 80 μm, and it has the properties of high temperature resistance and oil resistance.

[0052] It should be noted that the high-temperature resistant coating can adopt the high-temperature resistant coating in the prior art.

[0053] Furthermore, the upper rack 101 and the lower rack 102 are connected together by a spinning method.

[0054] By the spinning method, the outwardly turned edge 103 of the upper rack 101 encloses the narrow edge portion 106 near the edge of the side wall of the lower rack 102 for interference fit connection.

[0055] Corner pieces 107 are provided on the upper surface of the upper rack 101 for supporting cookware.

[0056] Footrests 108 are provided on the lower surface of the lower rack 102 to support on the cooktop panel.

[0057] This embodiment also provides a gas stove, including the pot rack provided in this embodiment.

[0058] For the gas stove provided in this embodiment, due to the use of the pot rack provided in this embodiment, it can reduce the heat transferred to the cooktop panel, effectively prevent the temperature of the cooktop panel from being too high, protect the panel from being damaged and cracked due to high temperature, and improve safety.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
