Description

TECHNICAL FIELD [0001] The present invention relates to an Internet cooking apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] More particularly, the present invention relates to a communication device capable of communicating with an external smart device using a thermoelectric element capable of converting heat or pressure generated during cooking into electric energy, or a piezoelectric element that converts pressure of a pressure field pot into electric energy, To an object Internet cooking apparatus capable of supplying operating power in a modular fashion and controlling the operation of the Internet through the Internet using information communicated through wireless communication between the communication module and the smart device.

Internet of Things (IoT) is an intelligent technology and service that connects all objects based on the Internet and communicates information between people, things, things and things.

Such Internet is more advanced than Internet or mobile Internet based on existing wired communication, and devices connected to the Internet can exchange information with each other without any physical manipulation of human being. It is similar to existing ubiquitous and M2M (Machine to Machine) in that things do not rely on human beings. But M2M, which is mainly used for communication with communication equipment and people, It is a stage that evolved into a concept that interacts with all information of reality and virtual world as well as objects.

Techniques for implementing this include sensing technology for obtaining information from objects of type and environment, wired / wireless communication and network infrastructure technology for supporting objects to be connected to the Internet, processing and processing information according to various service fields and forms Service interface technology that fuses various technologies is the key, and security technology to prevent hacking or information leakage of object Internet components such as a large amount of data is also essential.

For example, if you approach with a key, smart key that automatically unlocks the door of the car door and can start up without a key, smart grid that efficiently manages energy including electricity, gas or waterworks, . On the other hand, a separate controller, a control system, or a smart phone is required to control the object to which the object Internet is applied.

In order to implement functions with a device to which the Internet is applied, it is essential that a power supply that can be driven is basically provided.

In case of near field communication (NFC), which is used in daily life, one of the RFID technologies is a contactless communication technology using a frequency band of 13.56 MHz, which is theoretically within 10 cm Since a variety of wireless data can be exchanged at a short distance, communication can be possible only by placing an information device such as a smart phone in close proximity.

However, as seen from the living space where the noise signal is overflowing, for example, the traffic card, it is possible to recognize it by bringing it to 1 cm or less in actual situations.

On the other hand, there is a great difficulty in using the information device such as a smart phone in a container or a lid while cooking in a hot heat, because there is a risk of accidents due to high temperature and high temperature. Particularly, batteries are vulnerable to high temperature and humidity, and there is a risk of explosion, so that there is a limit to use in cookware.

For this reason, as a source of a power source capable of supplying driving power to a communication chip such as RFID, Bluetooth, or the like mounted on a device requiring operation under a high temperature condition such as a container under the cooking, However, there is a limitation that the device must be placed outside, and it is necessary to provide a method of supplying power using energy such as heat or pressure generated during cooking in an indoor space.

As a related art related to a technique of supplying electric power using a thermoelectric element, reference can be made to Published Unexamined Patent Application Nos. 10-2009-0106161, 10-1540186 and 10-0590693.

In addition, embodiments according to the concept of the present invention can make various changes and have various forms, so that specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

1 to 4, the Internet IoT cooking apparatus according to the present invention includes a cooking vessel 10, a fire-fighting apparatus 20 for applying energy such as heat, pressure, or electromagnetic wave to the cooking vessel 10, And a smart device 30 that enables communication on the cookware container 10 and the firepower device 20 in terms of the object Internet concept.

The cooking vessel 10 may include a container directly receiving energy such as heat or pressure from the fire-fighting apparatus 20, and a sealing lid detachably coupled to the upper portion of the vessel. The cooking container 10 converts energy such as heat or pressure received from the thermal power unit 20 into electrical energy and stores and supplies the energy to the smart vessel 30 through a communication module, Lt; / RTI >

The cooking vessel 10 is provided with a cooking vessel 10 for storing energy such as heat or pressure received from the thermal power unit 20 in the state of being placed on a container or a sealing lid, A power generation element 150 for converting energy such as heat or pressure into electric power in close contact with the transmission part 140 and a power generation element 150 for converting electricity generated by the power generation element 150 into uniform power And a storage unit 170 for temporarily storing the developed electricity.

The sensing unit 120 senses the electrical conductivity or the resistance value of the cooking vessel 10 and performs a self-diagnosis function to detect coating damage or packing damage of the cooking vessel 10. In order to assist in the self-diagnosis, it is possible to insert a diagnostic line into the cooking vessel 10 from the time of manufacturing the cooking vessel 10, or to use a built-in power line as an IH cooking apparatus for self-diagnosis.

The power generation element 150 is, for example, a structure in which electric power is produced by the temperature difference between the both surfaces of the Peltier element using heat. The power generating element 150 is a device using the Peltier effect and the Seebeck effect, and the whitening effect in which electric power is generated by the heat is generated when the P type semiconductor and the N type semiconductor provided in the Peltier element are connected to one plate Power is generated from the moment the heat is applied. The heat applied to the plate means that the free electrons present in the metal in the plate are energized, and the free electrons imparted energy tend to move somewhere. The energy-rich free electrons can move in the direction of the P-type semiconductor, so that the free electrons are drawn from the N-type semiconductor toward the P-type semiconductor, and the heated metal plate gives electrons to the P- And this shortage is drawn from the N-type semiconductor. Through such a process, a potential difference occurs between the electrodes connected to the circuit, resulting in a current flowing from the N-type semiconductor toward the P-type semiconductor, and the current generated by the completed Seebeck effect is proportional to the applied heat.

The heat supplied through the transmission unit 140 generates a temperature difference between the bottom surface and the top surface of the power generation element 150. As the temperature of the bottom surface of the power generation element rises, the temperature of the top surface of the power generation element decreases due to the Peltier effect And the power generated by the temperature difference between the bottom surface and the top surface of the thermoelectric element is supplied to the active RFID tag constituting the communication module 110.

For example, when the bimetal or the shape memory alloy is set to operate at 50 to 150 degrees, the heat supplied from the fire-fighting device 20 to the power generation device 150 is reduced .
