IH electric cooker and temperature reducing and controlling method thereof

Abstract

The invention discloses an IH electric cooker and a temperature reducing and controlling method thereof and belongs to the technical field of household appliances. The IH electric cooker comprises a cooker body, a cooker cover and an inner container. A fan is installed on the lower bottom ventilation surface of the cooker body, and the cooker cover is provided with an airflow path and can make airsequentially pass through the lower bottom ventilation surface and the outer side face of the inner container and then flow out of the top of the cooker cover. The cooker cover is also provided witha vacuum chamber for a microprocessor control module to be placed. The IH electric cooker is reasonable in structural distribution, easy to clean, good in internal ventilation and heat dissipation property and capable of effectively and quickly reducing temperature. In addition, intelligent and accurate temperature reduction and control can be achieved by virtue of micro-electronic elements. On one hand, different heating temperatures are controlled according to the heat demands at various rice heating stages, and scientific and standardized rice cooking is achieved; on the other hand, different internal temperatures are controlled at different working stages of the electric cooker, energy saving and protection of components and parts of the electric cooker are facilitated, and the fault occurrence rate is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of household appliances, in particular to an IH electric rice cooker. 【Background technique】 [0002] The working principle of the IH rice cooker is to directly heat the metal inner tank by connecting the electromagnetic induction coil with alternating current. Compared with the traditional rice cooker that heats the inner pot through the heating plate, the IH rice cooker has many advantages, such as the inner pot heating speed is fast, the firepower is strong, the rice is heated evenly and comprehensively, and the thermal efficiency is high. Existing electric rice cookers widely have such problems: the internal ventilation and heat dissipation of the entire electric rice cooker are not good, heating and heating are easy, cooling and temperature control is difficult, heating and heating are blind, and cooling and controlling the temperature and allowing it to cool down naturally has disadvantages such as p...

AI Technical Summary

Problems solved by technology

Existing electric rice cookers widely have such problems: the internal ventilation and heat dissipation of the entire electric rice cooker are not good, heating and heating are easy, cooling and temperature control is difficult, heating and heating are blind, and cooling and controlling the temperature and allowing it to cool down naturally has disadvantages such as passivity. The heat demand of rice in each heating stage controls different heating temperatures, realizes scientific and standardized cooking of rice, makes the rice taste delicious and has sufficient nutrients, and the inside of the rice cooker is heated at high temperature for a long time, which will easily lead to accelerated aging of the equipment itself, especially the microelectronic components. Affect the service life of the rice cooker, and the failure rate is high
