Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to an intelligent voice control system for preventing dry burning of a gas stove, timing and automatically detecting gas leakage. Background Art

[0002] At present, the gas stoves on the market cannot communicate with people by voice, and users cannot issue "timing" or "query" commands to the gas stoves by voice. When the gas stoves are abnormal, it is impossible to report the abnormal conditions of the gas stoves to the users by voice. On the other hand, the gas stoves and gas pipelines are prone to gas leakage due to aging caused by long-term use, and the leakage is not obvious and not easy to find. When the leaked gas accumulates to a certain concentration, it is easy to cause safety accidents.

[0003] In addition, most families like to stew or make soup. During the cooking process, they need to always pay attention to the burning of the gas stove. Sometimes, the user leaves the kitchen due to other things and forgets that the food is still being cooked, causing the gas stove to burn dry. This will not only burn the food and burn the kitchen utensils, but may even cause catastrophic safety accidents. Utility Model Content

[0004] In view of the deficiencies of the above-mentioned prior art, the utility model provides an intelligent voice control system for preventing dry burning of a gas furnace, setting a time and automatically detecting gas leaks.

If no one answers, the control system will directly shut down the gas furnace to prevent major accidents caused by dry burning of the gas furnace. The control system automatically detects the gas concentration. When the gas concentration exceeds the standard, the control system can intelligently determine whether the excess is caused by accidental incomplete gas combustion or by gas leakage, and report the judgment result to the user by voice in a timely manner.
