Ceramic electric cooker

Abstract

A pottery electric rice cooker, comprising: housing, upper cover, pottery inner cover, pottery inner container, heating device, temperature sensor, and circuit control device, the pottery inner cover is equipped with air gate, the temperature sensor is installed inside the housing near connection with upper cover, the upper cover is equipped with air gate relative to steam passage and air inlet of steam passage, the air gate of steam passage is relative to temperature sensor. The way of temperature measuring inside avoids abrasion and aging problem of wiring connecting temperature measuring element caused by frequent open on upper cover, and the pottery electric rice cooker is characterized by rational assembly and safer usage.

Description

technical field [0001] The invention relates to an electric rice cooker, in particular to a ceramic electric rice cooker capable of safe temperature measurement. Background technique [0002] At present, there are two commonly used temperature measurement methods for electric rice cookers, one is the contact temperature measurement at the bottom of the inner tank, and the other is the direct temperature measurement of the steam at the top of the inner tank. The former one is equipped with a temperature measuring device at the bottom of the inner pot. For the rice cooker with the inner pot made of purple sand ceramic material with a low conductivity coefficient and a large difference between the expansion coefficient and metal, the temperature measurement is inaccurate by using the bottom contact temperature measurement technology of the inner pot. , it is difficult to guarantee the effect and quality of cooking. The latter one uses the direct temperature measurement technol...

Problems solved by technology

The former one is equipped with a temperature measuring device at the bottom of the inner pot. For the rice cooker with the inner pot made of purple sand ceramic material with a low conductivity coefficient and a large difference between the expansion coefficient and metal, the temperature measurement is inaccurate by using the bottom contact temperature measurement technology of the inner pot. , it is difficult to guarantee the effect and quality of cooking

The latter one uses the direct temperature measurement technology of the steam at the top of the inner tank, which improves the temperature measurement accuracy, but because the temperature measurement element is installed in the upper cover, the temperature measurement signal must be connected to the control panel through the upper cover and the hinge of the casing. The frequent opening and closing of the cover, the wear and aging of the metal wires are easy to cause, causing leakage, temperature control failure and other problems
