Semiconductor chilling plate thermo-electric generation electronic temperature measurement pan

Abstract

The invention discloses an electronic thermometric pan with the function of electric generation by temperature differences of a semiconductor refrigeration piece, which mainly consists of a pan body, a handle, a temperature difference power generating system and a thermometric system. The temperature difference power generating system comprises the semiconductor refrigeration piece, a pressure-rising and voltage-stabilizing electronic component and an electric energy storage device. The thermometric system consists of a temperature sensor, a microprocessor, a circuit board and a liquid crystal piece. The temperature sensor is directly arranged at the bottom part of the pan body and the circuit board is arranged in a cavity of the handle. A cavity of the joint of the handle and the pan body is internally provided with the semiconductor refrigeration piece that is in contact with the pan body. The other surface of the semiconductor refrigeration piece is in close contact with a metal radiator. The temperature difference power generating system, the thermometric system and the liquid crystal piece are respectively connected with the circuit board. By utilizing cooking residual heat to generate power, the electronic thermometric pan of the invention realizes the temperature measurement for the bottom of the pan without battery drive, thereby not only becoming a healthy, hygienic and safe cook utensil, but also meeting the requirements of the times of environmental protection and economy; furthermore, the electronic thermometric pan of the invention also has convenient and reliable use, thereby having quite broad application prospect.

Description

technical field [0001] The invention relates to daily cooking utensils, specifically an electronic temperature measuring pot with a temperature display function. Background technique [0002] At present, if you can grasp the various data of the heating vessel (such as the temperature of the bottom of the pot) when processing food, it will not only help to process delicious food, but also prevent the temperature of the pot body from being too low to kill during food processing. The hygienic standard of germs may be too high to destroy the nutritional content of food, or even produce harmful substances. Therefore, existing patents have beneficially improved this, such as "a frying pan with temperature display function" disclosed in Chinese patent CN200520113972.8 and "electronic temperature display spatula" disclosed in CN200520128116.X. These patents apply the rapid and accurate characteristics of electronic temperature measurement to the food cooking process, and indeed pro...

AI Technical Summary

Problems solved by technology

However, since these electronic temperature measuring devices must be driven by batteries (disposable or rechargeable batteries), this brings unsafe, unreliable and inconvenient when the batteries are damaged, and inconvenience when disassembling and discarding the batteries. economical and environmental issues

These problems will affect the application of temperature measuring electronic cooking products and need to be upgraded
