The specific implementation mode is as follows:
the process of the present invention is further illustrated in detail by reference to the following examples. It should be noted that the protection scope of the present invention should include, but not be limited to, the technical contents disclosed in the present embodiment.
In the embodiment 1, the glass heating container of the invention comprises a glass body 1 and a glass bottom 2 integrated with the glass body, wherein the flatness tolerance of the bottom 3 of the glass bottom 2 is 0.02-0.30mm, the flatness tolerance of the bottom 3 of the glass bottom 2 is preferably 0.03-0.05mm, or 0.03-0.08mm, the thickness of the glass bottom 2 of the embodiment is 1.0-2.2mm, preferably 1.3-1.5mm, the adoption of the flatness tolerance of the bottom and the thickness of the glass bottom is a preferred scheme obtained by infinite tests, the larger the difference of the flatness of the bottom of the glass bottom, the heating efficiency of the glass will be deteriorated, the smaller the difference of the flatness, the processing difficulty is large, and a large amount of defective products will be generated, thereby increasing the manufacturing cost.
The main reason that the glass container as a water boiler cannot be widely popularized is that the heating efficiency of the water boiler of the existing glass container is extremely low, namely, as mentioned in the background art, 1200ml of water needs more than one hour for heating from 25 ℃ to 100 ℃, but the problem which cannot be overcome for a long time is overcome by the glass container, so that the glass container is a revolutionary product; the applicant finds through research that the reason that the heating efficiency of the glass container adopting the heating pipe arranged on the bottom surface is low is that the surface of the bottom surface of the glass container is high, low and extremely uneven in microscopic view, the contact between the heating pipe and the bottom surface of the glass container is line contact, the contact area is extremely effective, the heating efficiency is low and uneven, and even if the electric heating body constructed by the application is adopted as a heating source, the contact area between the electric heating body and the bottom surface of the glass container is still limited, and the heating efficiency is still low.
The flatness tolerance of 3 at glass bottom of cup bottom surface 0.05mm, thickness 1.5 mm's this application product passes through the experiment (the heating element who adopts in this experiment is the electric heat-generating body of this application structure) under the same heating power with current full glass kettle etc. condition, 1200ml water of this application heating container dress heats to 100 ℃ from 25 ℃ only need 13 minutes's time, and current full glass kettle dress 1200ml water heats to 100 ℃ needs 60 minutes's time from 25 ℃, the glass heating container of this application structure makes heating efficiency show the improvement.
Through tests, the heating container is filled with 1200ml of water and heated from 25 ℃ to 100 ℃ under the same conditions, the water boiling time is increased, and the water boiling time with the flatness tolerance of 0.02, 0.03, 0.04, 0.05, 0.08, 0.10, 0.13, 0.15, 0.18, 0.20, 0.25, 0.30, 0.40 and 0.50 mm is respectively 11.8 minutes, 12 minutes, 12.4 minutes, 13 minutes, 14.7 minutes, 16.9 minutes, 19.8 minutes, 22.7 minutes, 26.1 minutes, 29.3 minutes, 33.5 minutes, 38 minutes, 44.6 minutes and 51.3 minutes, so the flatness tolerance of 0.03-0.08mm is preferably adopted.
The whole body of the glass heating container is made of glass, and the glass heating container can be immersed into water for cleaning without any electronic element (the electronic element is positioned in the base, and the specific structure of the base is described in detail below), so that the dirt on the glass heating container can be completely removed, and the drinking water quality of people is ensured; meanwhile, the glass heating container does not generate electromagnetic radiation or infrared radiation generated by an electric ceramic furnace without using an electromagnetic heating technology, and does not have health influence on human bodies, and the glass heating container is simple to manufacture, low in cost and easy to sell, popularize and use; in addition this application is through base electric heat-generating body and the heat-conduction of bottom of cup for the face contact, heat conduction area is big and even, can be covered with tiny bubble at glass bottom of cup internal surface in the heating process, the noise that produces when tiny bubble explodes is less, and the electric heating pipe that current generally adds hot water kettle or transfers the milk ware is the ring form and fixes at the bottom of cup, make its heating concentrate on the round of ring, the bubble of production also concentrates on the round of this ring, at the in-process of heating up water, will produce the air blasting of great bubble because of heating inhomogeneous at the round of ring, arouse too big noise.
