Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas stoves, and in particular to a power generation mechanism and gas stove equipment. Background Art
[0002] Gas stoves have become the most essential cooking appliances in daily life, using gas as an energy source and the heat generated by combustion to cook food. As gas stoves become increasingly versatile, evolving from traditional mechanical stoves to intelligent stoves, they incorporate features such as display screens, dry-burn prevention, smoke / stove linkage, and timer control. These features significantly increase power consumption compared to traditional gas stoves, which only consume electricity for ignition.
[0003] At present, the main power supply methods for smart stoves are dry cell batteries and AC power supply. Due to the increase in power consumption, dry cell batteries require frequent battery replacement, which is very cumbersome, while AC power supply requires an additional power supply structure to be reserved during home decoration, which is also very inconvenient and leads to a poor user experience.
[0004] In order to solve the problem that smart stoves consume a lot of electricity and the existing power supply methods have many inconveniences, the industry mainly uses temperature difference power generation technology to achieve self-generation of gas stoves.
[0005] The technical principle of thermoelectric power generation technology is the Seebeck effect. When heat flows through a thermoelectric power generation element made of semiconductors and there is a temperature difference between its hot and cold ends, the thermoelectric power generation element can convert part of the flowing heat into electrical energy output. Therefore, the greater the temperature difference between the two ends of the thermoelectric power generation element, the more heat flows through the thermoelectric power generation element, and the greater the electrical energy it can output.
[0006] At present, although the existing thermoelectric power generation technology can achieve thermoelectric power generation, the following problems still exist: 1. The heat collection area at the hot end is small, making it difficult to effectively collect heat and ensure high temperature at the hot end; 2. The heat dissipation area at the cold end is small, and the cold end is close to the flame, making it difficult to dissipate heat efficiently and ensure low temperature at the cold end; 3. It is difficult to establish a large temperature difference between the hot and cold ends, so the output power is very limited, that is, the output power is small and cannot meet the power consumption requirements of the gas stove itself; 4. The heat collection structure will hinder the inflow of air, and the flame will touch the heat collection structure when burning, which will cause incomplete combustion of the gas. The incompletely burned gas will be directly discharged into the atmosphere, generating air pollutants, seriously polluting the environment and affecting the health of users, and also reducing the energy efficiency of the gas stove itself.

[0014] Furthermore, the plurality of second heat collecting parts together form a support structure for supporting cooking tools.
[0015] Furthermore, from the connection end of the second heat collecting part connected to the first heat collecting part to the free end of the second heat collecting part facing the fire-emitting component, the top surface of the second heat collecting part includes a first face portion and a second face portion, and the height of the second face portion gradually decreases; the second faces of multiple second heat collecting parts are used to jointly support cooking tools.
