Electromagnetic heating all-glass kettle capable of achieving automatic temperature control and energy conservation

Abstract

The invention relates to an electromagnetic heating all-glass kettle capable of achieving automatic temperature control and energy conservation. The kettle comprises a glass cup body, a high temperature resistant and anti-cracking glass base plate and an electromagnetic heating base; the bottom of the high temperature resistant and anti-cracking glass base plate or the side face of the glass cup body is provided with a temperature sensor for sensing liquid temperature inside the glass cup body, the high temperature resistant and anti-cracking glass base plate protrudes out of the bottom face to be provided with a first coupler, the upper portion of the electromagnetic heating base protrudes out of the top face to be provided with a second coupler, the outer rings of the first coupler and the second coupler are coupled to achieve signal communication, and a single-chip microcomputer controls on-off of a module electromagnetic induction coil circuit. The all-glass kettle adopts non-weight metal separation, the kettle is sanitary, clean and attractive, and the kettle is popular with consumers. Abrasion of the electromagnetic heating layer is reduced, and the phenomenon that surrounding people are scalded due to the fact that high temperature liquid is splashed in the heating process is avoided; dry burning is effectively avoided, the safety performance of the electromagnetic heating glass kettle is enhanced, the requirement for national coerciveness safety regulations is met, and meanwhile electric energy is saved.

Description

Technical field [0001] The invention relates to the technical field of an all-glass health-preserving kettle with electromagnetic heating and energy-saving, in particular to an electromagnetic heating all-glass kettle with automatic temperature control and energy-saving for the bottom surface of the glass kettle. Background technique [0002] At present, electromagnetic heating glassware on the market includes a microcrystalline panel, a coil plate, a control device and a bottom shell. The glassware is covered with a magnetic film on the bottom as the heating pot body. The glass pot is directly placed on the electromagnetic heating base for magnetic heating. The main problems are as follows: [0003] One is: During long-term use, the bottom of the glass kettle frequently rubs against the panel of the electromagnetic heating base, which makes the electromagnetic heating layer at the bottom of the glass kettle easy to wear and detach; [0004] The second is: the upper surface of the e...

AI Technical Summary

Problems solved by technology

[0003] One is: During long-term use, the bottom of the glass jug frequently rubs against the panel of the electromagnetic heating base, which makes the electromagnetic heating layer at the bottom of the glass jug easy to wear and tear off;

[0004] The second is: the upper surface of the electromagnetic heating seat and the bottom surface of the glass pot are smooth planes. During the electromagnetic heating process, the glass pot is placed directly on the top surface of the electromagnetic heating seat. Spilling high-temperature liquid during heating may easily cause burns to surrounding personnel;

[0005] The third is: during the use of the electromagnetic heating glass pot, personnel are required to stand beside the electromagnetic heating glass pot, and it is necessary to manually judge whether the heating has been completed according to the heating effect, and manually control the on and off of the power supply. Once the personnel leave, it is easy to cause dry burning , does not meet the requirements of national safety regulations

[0006] Fourth: Since this type of glassware is blown from high borosilicate glass, the thickness of the bottom is uneven, and the expansion coefficient is large, so it is easy to break in the environment of frequent hot and cold changes.

[0007] In addition, since the bottom of the pot is heated, the heat is high and stored on the panel of the electromagnetic heating base. During the heating process, the electromagnetic heating base heats up and becomes hot, which is easy to burn people, and the components in the electromagnetic heating base that are close to the panel, such as the coil plate , circuit boards, etc. are easily affected by heat radiation or high heat conduction temperature, which will affect the service life. At the same time, it also wastes electric energy, and the cost of use is high, which is not welcomed by consumers.
