Glass heating container and manufacturing method thereof

Abstract

The invention relates to a glass heating container and a manufacturing method thereof, and is characterized in that the glass heating container comprises a glass cup body and a glass cup bottom integrated with the glass cup body, wherein the planeness tolerance of the bottom surface of the glass cup bottom is 0.0230 mm; the glass heating container is reasonable in design, low in manufacturing cost, easy to sell, free of electromagnetic radiation, capable of being completely immersed in water to be cleaned and high in heating efficiency.

Description

Technical field: [0001] The invention relates to a glass heating container made of glass and a manufacturing method thereof. The glass heating container is mainly used for heating water, and is used as a milk mixer, a health pot, an electric kettle, a tea maker and other applied products. Background technique: [0002] At present, there are many kinds of kettles on the market, such as stainless steel kettles, glass kettles, IH heating milk kettles, all-glass kettles, etc., but these kettles have more or less disadvantages: [0003] For example, the heating elements of stainless steel kettles and glass kettles are all installed at the bottom of the kettle body. The bottom and water are generally made of stainless steel, and the surface needs to be polished. The polishing process is difficult to avoid the dust after polishing. During the heating process It will lead to the appearance of rust in different degrees and pollute the water quality; because the water quality is gener...

Problems solved by technology

[0003] For example, the heating elements of stainless steel kettles and glass kettles are all installed at the bottom of the kettle body. The bottom and water are generally made of stainless steel, and the surface needs to be polished. The polishing process is difficult to avoid the dust after polishing. During the heating process It will lead to the appearance of rust in different degrees and pollute the water quality; because the water quality is generally weakly alkaline, which contains Ca(HCO 3 ) 2 After the kettle body is heated, scale and other dirt are easily deposited on the heating plate. The kettle body cannot be completely put in water for thorough cleaning.

[0004] The IH heating milk conditioner is based on fixing the magnetic conductive material at the bottom of the glass body, so that the liquid in the glass is electromagnetically heated through the base with electromagnetic heating function. The defect of the IH heating milk conditioner is: electromagnetic heating will generate electromagnetic Radiation, especially for pregnant women and babies, will cause physical harm. It is not suitable for the human health needs of milk conditioners in the field of maternal and child products. The production cost of electromagnetic heating technology is high, which restricts the wide use and sales of products.

[0006] Another example is the current all-glass kettle, which is used for heating with an electric ceramic stove. The surface heating temperature of the electric ceramic stove is as high as 500°C, and the surface emits strong red light radiation. It is especially not suitable for mothers and babies under the requirement of dim light at night. The milk conditioner in the product field needs human health, and its thermal efficiency is low, so it cannot control temperature accurately
