Heat preservation heating system

Abstract

The invention discloses a heat preservation heating system which comprises a transduction device and a container. The transduction device is provided with a main control system, a wireless electric energy transmitting module and a power supply. The container is provided with a terminal control system, a wireless electric energy receiving module and a heating module. The main control system is in communication connection with the terminal control system. According to the invention, wireless transmission and conversion of electric energy are realized through the wireless electric energy transmitting module and the wireless electric energy receiving module; compared with an existing wireless heating mode based on the eddy current effect, the provided mode is more stable, safer and more reliable; and in order to solve the problems that a heating device is poor in controllability, has no recognition system, can generate adverse effects on a heating body and the like through the eddy currenteffect, the system adopts wireless power transmission to provide electric energy, and then, utilizes a traditional electric heating mode for heating to realize functions of heat preservation and thelike.

Description

technical field [0001] The invention relates to the technical fields of tableware and electric appliances. Specifically relates to a thermal insulation heating system. Background technique [0002] Most of the existing electric heating or electric heat preservation methods are direct heating. For example, in many fast food industries, food needs to be prepared in advance. During this period, the heated dishes will gradually cool down, so they need to be stored in heat preservation equipment so as not to affect Food taste and dish quality. However, direct heating type heating or heat preservation equipment has various problems, such as water stains, oil stains, and unstable heat conduction. [0003] Regarding the three disclosed patents with similar functions, they have the following deficiencies in terms of practicability: [0004] 1. Chinese invention patent CN200920178308.X discloses a heat preservation and heating device for table and tray. Among its inventions: [0...

AI Technical Summary

Problems solved by technology

[0005] (1) There must be a power transmission base at the bottom of the dinner plate, and the environment of the dinner plate is mostly high temperature and high humidity, easy to contact with water and oil, this environment is extremely inconvenient for the power transmission of the power transmission base type, and the exposed power interface is easy to cause leakage wait for danger

[0006] (2) There is a heat preservation and heating function for dishes, but it cannot provide users with accurate temperature selection and control, and most dishes have different suitable heat preservation and heating temperatures

[0007] (3) There is no heat insulation function of the outer wall. When the heat preservation is heated, the temperature of the outer wall will increase accordingly, which will bring the risk of burns to the user

Introduce alternating current into the dinner plate, because the use environment of the dinner plate is mostly high temperature and high humidity, easy to contact with water and oil, and the exposed power interface may easily lead to dangers such as leakage

[0010] (2) There is a heat preservation and heating function for dishes, but it cannot provide users with accurate temperature selection and control, and most dishes have different suitable heat preservation and heating temperatures

[0011] (3) There is no heat insulation function of the outer wall. When the heat preservation is heated, the temperature of the outer wall will increase accordingly, which will bring the risk of burns to the user

[0014] (2) There are many parts and components. To complete the function, a large number of parts need to work at the same time. If there is a problem in a certain link, the function cannot be completed. The reliability of the device is high and the cost is high

[0020] 1. Based on the eddy current effect, only the bottom of the container can be heated, but the wall of the container cannot be heated;

[0021] 2. The container cannot actively control the heating power, and needs to rely on the energy supply chassis (placemat), resulting in uncontrollable temperature; and through wireless energy transmission, the heating power is only performed by the container, and the temperature is controllable;

[0023] 4. If the container enters the working state with no load, the heat generated by the eddy current will deform or even melt its own metal, and the transmitter cannot know whether it is empty and change the power, which is dangerous and inconvenient to use
