Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, and in particular to a power generation system 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 additional power supply structure to be reserved during home decoration, which is also very inconvenient.

[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] Currently, the waste heat from the flame of a gas stove is typically used as a thermal energy source. However, collecting this waste heat is extremely difficult, making it difficult to generate enough electricity to power the stove itself. Heat from the flame is dissipated directly into the air, making it inefficient to collect this waste heat from the air through convection heat transfer. The heat collection structure remains low, making it difficult to maintain a high temperature at the hot end of the thermoelectric generator. The cold end is too close to the flame, making it difficult to dissipate heat effectively and maintain a consistently low temperature at the cold end. The electricity generated by the thermoelectric generator after the collected heat is converted is insufficient to achieve self-sufficiency in the gas stove's intelligent functions.

[0007] The heat energy of a gas stove comes from the combustion of the gas stove. The relevant patents all collect heat from the flame burning on the burner. The heat transfer path of the general heat collection process is flame → air → heat collection structure → hot end of the thermoelectric generator, or flame → air → burner, panel and other parts of the gas stove structure close to the flame → heat collection structure → hot end of the thermoelectric generator. However, since air is a poor conductor of heat, it is extremely difficult to collect heat from the air, resulting in poor heat collection effect, low output power, and inability to achieve self-sufficiency in power for the gas stove.

[0008] It can be seen that the existing technical solutions have the problems of low heat extraction efficiency, extremely small amount of heat energy that can be effectively collected, small output power, and inability to meet the power consumption requirements of the smart stove itself.

[0036] The utility model provides a power generation system 100, please refer to Figures 1 to 4The power generation system 100 includes a combustion chamber 10, a thermoelectric power generation component 20 and a cooling component 30; the cavity of the combustion chamber 10 is used to communicate with the gas supply pipeline of the gas stove, so that the gas in the gas supply pipeline of the gas stove flows into the cavity of the combustion chamber 10 and then burns in the cavity of the combustion chamber 10; the thermoelectric power generation component 20 is arranged on the outside of the combustion chamber 10, and the thermoelectric power generation component 20 is in contact with the outer wall of the combustion chamber 10, so that the heat generated by combustion in the combustion chamber 10 is transferred to the surface of the thermoelectric power generation component 20 in contact with the combustion chamber 10, so that the surface of the thermoelectric power generation component 20 in contact with the combustion chamber 10 forms the hot end of the thermoelectric power generation component 20; the cooling component 30 is arranged on the outside of the thermoelectric power generation component 20, and the cooling component 30 is in contact with the thermoelectric power generation component 20, so that the cooling component 30 cools the surface of the thermoelectric power generation component 20 in contact with the cooling component 30, so that the surface of the thermoelectric power generation component 20 in contact with the cooling component 30 forms the cold end of the thermoelectric power generation component 20. The power generation system 100 of the present invention outputs relatively large amounts of electrical energy, so that the electrical energy outputted by the power generation system 100 can achieve self-sufficiency of the gas stove.

[0037] Specifically, the power generation system 100 is a micro combustion chamber temperature difference power generation system for a gas stove, and the combustion chamber 10 is a micro combustion chamber.

[0038] It should be noted that the principle of thermoelectric power generation is to use PN junction semiconductor materials to make a thermoelectric power generation component 20, and the thermoelectric power generation component 20 converts heat into electrical energy output.

[0039] Specifically, the gas supply pipeline of the gas stove is communicated with the burner 50 of the gas stove to supply gas to the burner 50 .

[0088] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0089] In the power generation system 100 provided by the present invention, the power generation system 100 includes a combustion chamber 10, a thermoelectric power generation component 20 and a cooling component 30; the cavity of the combustion chamber 10 is used to communicate with the gas supply pipeline of the gas stove, so that the gas in the gas supply pipeline of the gas stove flows into the cavity of the combustion chamber 10 and then burns in the cavity of the combustion chamber 10; the thermoelectric power generation component 20 is arranged on the outside of the combustion chamber 10, and the thermoelectric power generation component 20 is in contact with the outer wall of the combustion chamber 10, so that the heat generated by combustion in the combustion chamber 10 is transferred to the surface of the thermoelectric power generation component 20 in contact with the combustion chamber 10, so that the surface of the thermoelectric power generation component 20 in contact with the combustion chamber 10 forms the hot end of the thermoelectric power generation component 20; the cooling component 30 is arranged on the outside of the thermoelectric power generation component 20, and the cooling component 30 is in contact with the thermoelectric power generation component 20, so that the cooling component 30 cools the surface of the thermoelectric power generation component 20 in contact with the cooling component 30, so that the surface of the thermoelectric power generation component 20 in contact with the cooling component 30 forms the cold end of the thermoelectric power generation component 20. The power generation system 100 of the present invention outputs relatively large amounts of electrical energy, so that the electrical energy outputted by the power generation system 100 can achieve self-sufficiency of the gas stove.

[0090] The present application provides a thermoelectric power generation structure with a micro combustion chamber, which collects heat in the form of conduction and can construct a large temperature difference between the hot and cold ends of the thermoelectric power generation component 20 to ensure output power.

[0091] The power generation system 100 of the present application: 1. It includes an independent micro-combustion chamber. A portion of the gas is drawn from the gas pipeline of the burner and burned in the chamber. The micro-combustion chamber absorbs the heat energy generated by the combustion, preventing the heat from being dissipated into the air. Because the chamber 10 is a closed structure, the majority of the released heat energy is absorbed by the combustion chamber 10 itself, resulting in minimal heat loss. 2. The hot end of the thermoelectric power generation component 20 is directly attached to the outside of the micro-combustion chamber. There is no other thermal resistance during the heat transfer process. The hot end of the thermoelectric power generation component 20 can directly absorb heat from the combustion chamber through conduction, ensuring that the hot end of the thermoelectric power generation component 20 is continuously at a high temperature. 3. The cold end of the thermoelectric power generation component 20 is attached to the cooling component 30, that is, the cold end of the thermoelectric power generation component 20 is attached to the inner wall of the receiving space 33. The coolant flowing in the cooling component 30 removes excess heat, ensuring that the cold end of the thermoelectric power generation component 20 is kept at a low temperature, allowing heat to flow continuously through the thermoelectric power generation component 20, thereby generating a large amount of electricity. 4. The output power of the temperature difference power generation component 20 is greatly improved to ensure that its self-generated power can meet the power consumption demand of the gas stove. There is no need for an external power supply or battery replacement, which greatly improves the user experience.
