Description

Nonmetal heating device is used in culinary art

Technical Field

The utility model relates to the technical field of household appliances, in particular to nonmetal heating device is used in culinary art.

Background

Kettles are necessities of life, and products are continuously updated from gas kettles, intelligent plastic electric kettles, stainless steel electric kettles, half-glass kettles and full-glass kettles. The glass has stable physical characteristics, is safe and clean, does not produce chemical reaction with heated food, does not have the worry of heavy metal, and the transparent body of the glass can penetrate through far infrared rays, thereby improving the water quality and optimizing the water source.

The prior all-glass kettle mainly has the following technologies: transparent nanofilms, carbon films, and thick films. The former two kinds of power decay fast, which have been abandoned by various manufacturers, the latter has good power stability, but the process requirement is high, and the processing index of the glass body is strict, for example: smoothness, thickness uniformity, compactness, freedom from bubbles, craters, etc. Any one of the indexes can not reach the standard, the electrothermal film is easy to generate hot junction and micro-flash discharge, the instantaneous temperature rises, and finally, the glass body is broken. Further, the heat generating film needs to be matched with the temperature characteristics and thermal expansion coefficient of glass, and to be well adhered and wetted to the glass. And the heating film slurry is fired and tested after being prepared, the testing period is long, uncertain factors are large, and once the physical property of the glass is changed, the glass needs to be prepared again for a long time.

The processing level of the current glass at home and abroad can not meet the processing index. Therefore, a solution to replace the boron silicate glass with high economical efficiency with the quartz glass with high cost is available. However, the cost of quartz glass is several tens times that of borosilicate glass, and although the thickness, smoothness and bubble hollow of quartz are superior to those of borosilicate glass, the quartz has high melting point, so that the pot body is difficult to form and process, the cost is huge, and the quartz glass cannot be produced in mass.

In order to solve the inherent drawbacks of glass materials, other solutions have appeared over the years, such as: and (3) cutting the bottom glass kettle body, namely embedding the ceramic heating plate/microcrystalline heating plate and the silica gel sealing ring on the bottom glass kettle body to form the pseudo-full-glass health preserving kettle. Because the metal heating plate is directly contacted with the heating liquid, the heat transfer efficiency can be improved, but the concept of full glass is damaged, and in the process of heating and boiling food, the food and silica gel chemically react to cause pollution, color change and standard exceeding of heavy metals. Moreover, the transition place of the sealing ring and the heating element is often a dead angle for cleaning, and the safety and the sanitation can not be ensured. In addition, the sealing consistency of the above structure is not good, and mass production cannot be realized.

For another example: the heating film is directly attached to the kettle body, and local overheating is easily caused due to poor heat conduction of the kettle body material, so that the heating film is ablated due to overheating, and the kettle body is likely to break due to uneven cold and hot shrinkage of the kettle body material.

The following steps are repeated: the external radiation scheme, place the quartz heating pipe promptly at glass kettle bottom, heat flourishing water glass container, its shortcoming is: high bottom heat, glare by visible light, inaccurate control system, etc.

Namely, the current scheme of the all-glass kettle can not simultaneously meet the problems of low cost, long service life, safety, mass production, easy cleaning and the like.
