Background technique

According to the example of household appliances with baking function on the market, high temperature resistant metal materials are generally used as the inner liner and outer casing of the household appliance, and then the heat generating device is installed in the inner tank. When working, the heating device generates heat to heat the food, and the inner casing and outer casing of the household appliance are used to prevent heat loss and ensure heating quality. However, due to its thermal conductivity, the heat and heat generated by the heat-generating device are dissipated in the air by a large amount of the heat-resistant metal material. Only a small amount is used to heat the food, resulting in heat. The utilization rate is low and the heating effect is not satisfactory. In order to reduce the heat conducted by the inner liner and the outer casing, the thickness of the metal plate for increasing the inner liner and the outer casing is generally used. Although this can reduce the heat dissipation within a certain range, it also increases the production cost of the baking appliance. The quality of baking appliances is cumbersome, which is not conducive to market competition.

BEST MODE FOR CARRYING OUT THE INVENTION

The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, so that those skilled in the art can implement the present invention after studying the present specification.

Referring to FIG. 1 and in conjunction with FIG. 2, a rapid heating structure of a food baking apparatus includes a tank 10 and a door 20 coated with a reflective layer 30 formed of a high temperature resistant material, and a cavity of the liner 10. A heat generating device group 40 installed in the body 11, wherein:

The inner liner 10 is formed of a metal sheet, is wrapped in the outer casing 50 of the food baking equipment, and forms a space 51 with the outer casing 50; the inner casing 10 is composed of a top wall 12, a bottom wall 13 and two a side wall (not labeled) is formed with a cavity 11;

The door 20 is mounted to the outer casing 50 by a hinge. When the door 20 is closed, the door 20 is engaged with the inner casing 10 encased in the outer casing 50, and the cavity of the inner casing 10 is also combined. 11 forming a closed heat insulator with the outside, the door 20 includes the inner glass 22 and the outer glass 23 respectively covered by the door frame 21 and the door frame 21, and the inner and

outer glass

22, 23 are separated by the door frame 21 Forming a heat insulating space 24 of a double-glazed door, the inner and

outer glass

22, 23 being formed of a heat resistant material such as glass reinforced plastic and/or quartz glass;

The reflective layer 30 is sprayed on the wall surface of the inner tube 10 and the inner glass 22 toward the cavity 11. The reflective layer 30 is formed of a high temperature resistant coating, wherein the high temperature resistant coating comprises composite silicic acid. Magnesium-aluminum thermal insulation coatings, rare earth thermal insulation coatings, coated composite silicate thermal insulation coatings, and refractory thermal insulation ceramic coatings, although they have different product names, are basically inorganic and/or organic binders. Insulation aggregates (such as sepiolite, vermiculite, perlite powder, etc.), and air entraining agents. From the functional characteristics of such high-temperature resistant coatings: First, barrier thermal insulation is achieved by low thermal conductivity and high thermal resistance. The most widely used barrier thermal insulation coating is composite silicate insulation. Thermal insulation coating (for specific performance requirements, please refer to GB/T17371-1998 "silicate composite thermal insulation coating"); second, it has reflective heat insulation function, which is developed on the basis of adsorption aluminum-based reflective thermal insulation coating. The high-reflectivity coating is prepared by selecting suitable raw materials and formulas, and the heat-reflecting coating of the thin-layer heat-insulating reflective coating formed by spraying on the surface of the metal is high, generally above 80%, and the heat insulating effect is obvious. When used, it is generally modulated in a light color system, such as white or silver. In the preferred solution created by the present invention, the high temperature resistant paint is applied to the surface layer of the inner liner 10 of the food baking device by spraying. Not only can the heat source be effectively reflected in the cavity 11 of the inner liner 10, but also the inner liner 10 can be directly subjected to the intense high temperature baking, thereby prolonging the service life of the inner liner 10, and at the same time, coating the inner surface of the reflective layer 30. The gallbladder can effectively reduce or block the external heat dissipation, thereby not only releasing the safety hazard during use, but also effectively improving the utilization rate of the heat energy in the cavity 11.

The heat generating device group 40 is disposed in the cavity 11 and connected to a circuit mechanism (not shown) of the food baking device.
