Description

The present invention relates to a kettle that can be used as a lantern.

In recent years, the tendency to improve the way of spending at home has become widespread worldwide. Lanterns that emit a relaxing light are attracting attention as interior goods.

In order to use electric power to emit light from a lantern, it is necessary to supply electric power to the light source of the lantern. Although there are various means for supplying power to the lantern, it is necessary to connect a power cord to the lantern in order to supply power from an outlet such as a household power supply. It is desirable to eliminate the cord in order to improve the design as an interior product. Batteries can also be used to power the lantern, but there is a concern that the batteries will run out.

As a lamp that does not require the preparation of a dry battery, for example, as described in Patent Document 1, a thermoelectric lamp provided with a thermoelectric element that generates a voltage by the Zeebeck effect is disclosed. By grasping it with a hand, one joint of the thermoelectric element is heated, and the other joint is cooled from the heat radiation fins, causing a temperature difference, and the voltage generated in the thermoelectric element by the Zeebeck effect is supplied to the lamp. By doing so, it is disclosed that the lamp is turned on.

On the other hand, kettles are used to boil water and keep it warm. In a conventional kettle, after boiling hot water or the like is put into the kettle, heat is released into the outside air and the hot water is gradually cooled. Further, after the cooled liquid such as ice water was put into the kettle, the heat was gradually absorbed and the temperature of the liquid was gradually warmed up.

Circuit 8 is connected to Pelche element 6 and LED 7. The circuit 8 is configured to supply the electric power generated by the Pelche element 6 to the LED 7 to make the LED emit light.

In the kettle lantern 1 shown in FIG. 1, a liquid having a temperature different from that of the outside air is poured into the inside of the kettle main body 2. The liquid may be a liquid having a temperature higher than the outside air such as hot water, or a liquid having a temperature lower than the outside air such as ice water. As shown in FIGS. 1 and 3, when a liquid is poured, a temperature difference occurs between the inside of the kettle body 2 and the outside air with the lid 3 sandwiched between them. When hot water is added to the kettle body 2, the temperature inside the kettle body 2 is high and the outside air temperature is low. When ice water is put into the kettle body 2, the temperature inside the kettle body 2 is low and the outside air temperature is high. The Pelche element 6 utilizes this temperature difference to generate a voltage. The generated power is supplied to the light source 7 as a direct current through a circuit.

The LED 7 irradiates the liquid inside the kettle body 2 with the supplied electric power. The light radiated to the liquid diffusely reflects and diffuses the light, softly illuminating the surroundings. For example, in FIG. 1, the light from the LED 7 installed in the center of the lid 3 is shown by a dark shadow from the lid 3 to the base 10. Similarly, in FIGS. 10 to 13, the light from the LED 7 installed in the center of the lid 3 is shown by a dark shadow from the lid 3 to the base 10. When the light from this LED 7 is dropped into a liquid, the entire kettle body 2 becomes bright like a lantern.

The Pelche element 6 installed on the lid 3 changes the voltage generated according to the temperature difference between the internal temperature of the kettle main body 2 and the outside air temperature. For example, immediately after putting water in the kettle body 2 and boiling water, the temperature inside the kettle body 2 is high, but the temperature gradually decreases and approaches the outside air temperature. Therefore, immediately after adding hot water, a larger current is generated in the Pelche element 6 and the LED 7 emits more intense light. On the other hand, as the temperature inside the kettle body 2 decreases, the electric power generated by the Pelche element 6 decreases, and the light emission of the LED 7 also weakens. In this way, you can enjoy the intensity of the LED7 light by changing the temperature. On the other hand, if ice is put inside the kettle main body 2, the temperature inside the kettle main body 2 becomes lower than the outside air, so that electric power is generated by the Pelche element 6 and the light of the LED 7 can be dropped on the ice. By illuminating the colored liquid such as herbal tea with the light of LED7, you can enjoy the change of light.
