Description

[0001] HEATING CONTAINER FOR USE OF THERMOELECTRIC GENERATOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heating container for a thermoelectric generator and more particularly to a heating container for a thermoelectric generator capable of generating electricity by utilizing thermal difference between high temperature steam inside a heating container such as a pot and ambient temperature outside the heating container.

Thermoelectric Generation is a technology that converts heat energy directly into electric energy. It is a concept that the heat generated by the difference in temperature between the high temperature part and the low temperature part is converted into electric energy. By using the Seebeck effect, which generates an electromotive force by applying an electric current to both ends of a material (device) connected with two different metals, thermal energy is converted into electric energy when there is a temperature difference between both ends of the semiconductor material Technology.

Such a thermoelectric power generation can be stably produced for 24 hours if a stable heat source can be secured as compared with a solar cell influenced by the weather or the amount of sunshine. In particular, because it uses solid-state electronic circuits, there is no operating part, and the structure is simple and the available heat sources are varied, and it is attracting attention as a new alternative energy technology as a response to global warming and high oil prices.

Recently, high-temperature heat generated in industrial facilities such as the heat released through the chimney of the factory, the heat discarded from the general power generation facility, and the heat released from the smelter is used as a power source by using a medium-sized thermoelectric generator.

However, in spite of the fact that high temperature is generated in an outdoor environment through a home or a leisure life rather than an industrial facility, the heat generated is not utilized properly. Especially, in a kitchen where food is cooked, a considerable amount of heat is generated at a high temperature through a heating container such as a pot. However, it is safe to say that a technique using such heat has not been proposed yet.

2 is a side cross-sectional view showing a heating container which serves as a thermoelectric generator according to another embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the heating container for both thermoelectric generators according to the embodiment of the present invention includes a container body 20 for heating the inner receptacle largely through heat energy externally applied thereto, A low temperature section 44, a thermoelectric module 46, and a load section 49 are provided in the lid section 40. The high temperature section 44, the thermoelectric module 46, and the load section 49 are formed in the lid section 40 do.

The high temperature part 42 is bonded to the lower surface of the lid part 40, and receives heat of high temperature from the steam generated by heating the contents of the container body 20. The high temperature part 42 completely encloses the lower surface of the lid part 40, thereby securing a maximum area for receiving high temperature heat. It is preferable that the entire high temperature section 42 is completely closed from the outside when the lid part 40 closes the upper part of the container body 20 to prevent the heat of high temperature from diffusing and discharging to the outside. Here, the high temperature part 42 is made of a material that is easy to transmit heat, and minimizes the loss of heat energy from the high temperature steam and transfers it to the thermoelectric module 46.

The low temperature section (44) is provided to face the high temperature section (42) and forms a path through which the external gas passes. The low-temperature portion 44 is exposed to the outside even when the lid portion 40 closes the upper portion of the container body 20. Here, it is preferable that a plurality of radiating fins (48) protrude from the inside to the outside at the low temperature part (44). Accordingly, the temperature inside the low-temperature section 44 can be kept relatively low as compared with the case without the heat-radiating fins 48, which means that the thermal difference between the high-temperature section 42 and the low- do. The radiating fins 48 protruding outside the low temperature portion 44 preferably have a curved shape at an end portion of the radiating fin 48. This prevents the occurrence of injury to the user's body due to the protruding portion of the radiating fins 48 do.

The thermoelectric module 46 is joined between the high temperature part 42 and the low temperature part 44 to convert thermal energy due to the temperature difference between the high temperature part 42 and the low temperature part 44 into electric energy. The thermoelectric module 46 is formed by arranging n-type and p-type thermoelectric elements between insulating substrates made of ceramics such as alumina. Accordingly, if a constant temperature difference is formed between both ends of the thermoelectric module 46, a direct current voltage is generated due to the whitening effect, and electric energy can be obtained.

The load unit 49 is provided on one side of the lid unit 40 and is electrically connected to the thermoelectric module 46 to provide a DC voltage generated by the thermoelectric module 46 to the outside. The load section 49 has a charging terminal for charging various electronic appliances and the like. The standard of the charging terminal may be variously selected by a person skilled in the art depending on the type of portable equipment, and a conversion gender may be separately provided. As a result, it is possible to reduce electricity costs by charging low-power electronic devices at home, and it is possible to extend the use time by charging portable devices at every outdoor time. As described above, according to the present invention, by using thermoelectric power generation in a heating container used for cooking in a home or outdoor, high-temperature heat which can be consumed unintentionally can be converted into electricity, thereby enabling environmentally friendly power generation.

At least one light emitting device 80 electrically connected to the thermoelectric module 46 is provided on the lid unit 40.

As shown in FIG. 2, the LED 80 may be provided on the upper surface of the lid 40. Accordingly, it is possible to improve the beauty during cooking and to emphasize visibility that requires careful attention during cooking, thereby preventing a stable accident. A plurality of ornamental LEDs 82 are arranged in various colors to enable selective emission according to the situation. For example, the number of LEDs that emit light may be limited or extended according to the amount of power supplied from the thermoelectric module 46, or LEDs of a specific color may be selected to emit light, thereby providing a nice warning during cooking, and a warning message requiring attention.

As shown in FIG. 2, the light emitting device 80 may be provided on the handle side of the lid 40 with the LED 84 for illumination. Accordingly, the heating container and its surroundings are illuminated outdoors so as to facilitate cooking at night. At this time, the lighting LED 84 uses a plurality of high-intensity white LEDs to maintain a constant brightness around the heating vessel. Such an LED for illumination 84 eliminates the lamp that had to be used separately at night, thereby reducing the cost of the auxiliary power supply and improving the convenience of night cooking.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the claims of the invention to be described below may be better understood. The embodiments described above are susceptible to various modifications and changes within the technical scope of the present invention by those skilled in the art.
