Embodiment Construction

[0013] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as Figure 1 ~ Figure 4 As shown, the fire cover of the present invention is formed by integral casting of aluminum alloy, and all surfaces of the aluminum alloy substrate of the fire cover are subjected to hard anodic oxidation surface treatment, and a porcelain hardened aluminum alloy substrate is formed on the surface of the aluminum alloy substrate 2 of the fire cover. Hard anodized film 1, the thickness of the hard anodized film 1 is not less than 0.08mm, the hard anodized film 1 includes a non-porous layer 12 and a porous layer 13 distributed in sequence from the aluminum alloy substrate 2, the non-porous layer 12 and the The aluminum alloy matrix 2 is interpenetrated and bonded.

[0015] In the above solution, the fire cover can also be formed by extruding aluminum alloy plates, pipes, and rods.

Abstract

The invention discloses a porcelain fire cover of a gas stove burner, and belongs to the field of gas cookers. A traditional copper burner fire cover can be corroded easily in itself, heat transfer is likely to happen, and thus a furnace end can be oxidized and corroded easily; and due to the high weight, dismounting and cleaning are inconvenient. The fire cover disclosed by the invention is made of aluminum alloy, and all the surfaces of an aluminum alloy matrix of the fire cover are subjected to hard anodizing surface treatment. A porcelain hard anodic oxide film wrapping the aluminum alloy matrix is formed on the surfaces of the aluminum alloy matrix on the fire cover. The thickness of the hard anodic oxide film is not smaller than 0.08mm, and the hard anodic oxide film and the aluminum alloy matrix infiltrate with each other to be combined. Hence, the fire cover is resistant to corrosion, high temperatures and abrasion, long in service life, convenient to dismount and clean, and capable of reducing manufacturing cost.

Description

technical field [0001] The invention belongs to the field of gas stoves, and in particular relates to a porcelain fire cover for a gas stove burner. Background technique [0002] The burner of the gas stove mainly includes the burner and the fire cover installed on the gas mixing chamber of the burner. The fire cover is in direct contact with the flame. According to the requirements of the industry standard, it must be able to withstand a high temperature of 700°C. Commonly used burner fire caps are made of copper. Copper fire caps are heavy and inconvenient to disassemble, maintain and clean. Copper resources are relatively scarce. Copper fire caps are easily corroded. Copper is a good conductor of heat. A large amount of heat will be generated during combustion, and part of the heat will be transferred to the burner burner head through the fire cover, making the burner head become high temperature during combustion. A loose oxide layer, the oxide layer is easy to peel off...
