Electric heating cooking utensil with wireless steam detection device

Abstract

The invention discloses an electric heating cooking appliance with a wireless steam detection device, which is a detection device for detecting the temperature, humidity, flow velocity and flow data signals of the steam flowing into the atmosphere through the pot cover in different boiling states of the liquid with wireless transmission and reception. On the pot lid of the electric cooking appliance that is detachable from the pot body or utensils and has no signal transmission wires, this effectively solves the problem that the pot lid and the pot body or utensils can be separated. The electrothermal liquid heating appliance is susceptible to product structure, heating method, and material changes , use environment, operation method, aging deformation, commercial pots of different specifications, etc., especially the changes in altitude, which cause existing problems such as electric rice cookers, electric pressure cookers, electric steamers, and electric stew pots. It has realized the intelligent judgment, adjustment and control of the cooking process when the electric heating stoves such as induction cooker, electric ceramic stove, health pot, electric tea set, and light-wave oven are performing the function of "steaming, cooking, and stewing".

Description

technical field [0001] The invention relates to the technical field of electric cooking, in particular to a pot cover that can be separated from the pot body or utensils. On the outside of the upper part of the pot cover, there is an electric heating device that can detect steam temperature, humidity, flow rate and flow rate, and can send and receive detection data signals wirelessly. cooking utensils. Background technique [0002] For electric heating liquid heating appliances such as electric rice cookers, electric steamers, electric saucepans, electric pressure cookers, electric hot pots, and electric kettles whose lids are detachable from the pot body or appliances, the signal used to control the cooking process of the appliances is obtained by using the bottom or Side indirect temperature measurement, or a method of directly inserting a temperature sensor into a container to detect the temperature of a liquid or steam; as an induction cooker, an electric ceramic stove, ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the electrothermal liquid heating appliance whose lid is detachable from the appliance or the pot body, and the electric heating cooking appliance composed of the electric heating stove, especially the electric heating cooking appliance using a non-metallic pot body, do not have a reliable and stable detection scheme. As a result, the product is easily affected by factors such as structure, heating method, use environment, operation method, aging deformation, etc., causing performance problems such as overflow and dry burning, and even causing personal and property injury accidents in severe cases

In order to solve the deficiencies in the traditional detection technology of existing electric cooking appliances, patent No. CN200420083296. The boiling point, and the steam temperature of different sections of the same section are greatly affected by the product structure and environment of the split pot cover, so the technical solution of the top temperature measurement can only partially solve the shortcomings of the traditional technical solution; and the patent number CN201621098434.0 The patent of "New Measurement and Control Device for Electric Cooking Appliances" discloses the steam detection technology, and uses reliable and stable liquid boiling data signals to effectively solve the problem of one-piece electric cooking appliances, which are affected by changes in altitude and pot material, and the top Product performance and quality problems caused by temperature measurement, but because this technical solution must use wires to transmit detection signals, it is only applicable to appliances with signal transmission lines connected to the controller as a whole.
