Description

TECHNICAL FIELD [0001] The present invention relates to a heating control system using a smart plug,

The present invention relates to a heating control system and method using a smart plug, and more particularly, to a heating control system and method using a smart plug, in which electric power supplied to a heating device is cut off to prevent overheating of a heating device contacting or non- And more particularly, to a heating control system and method using a smart plug that increases the effect of reducing electricity consumption due to an increase in temperature and a prevention of overheating.

Auxiliary heating devices that use electricity in general include electric plates, hot water mats, radiators, convectors, and electric heaters. A conventional auxiliary heating apparatus uses a heating controller to control heat radiated.

The conventional heating controller controls the surface temperature by adjusting the amount of power input in each set-up step. Although manufacturers' manuals show surface temperature for each set step, users often do not recognize the surface temperature without looking at the manual. Even at the same setting step, the surface temperature varies depending on the ambient temperature, and the surface temperature may vary even when covering the blanket.

Therefore, as long as the heating time has elapsed, there is a high possibility that the surface temperature of the electric plate and the hot water mat becomes overheated and the temperature may be lowered unless the user is interested and frequently changes the setting step.

Also, in the case of houses and buildings, since the room temperature is frequently changed according to the outside temperature and the indoor main heating condition, it is necessary to precisely control the temperature based on the measurement temperature to improve the comfort according to the room temperature.

Such a conventional heating controller is equipped with a component overheating prevention function (an overcurrent shutdown function by an overheat prevention device operating at about 150 to 200 DEG C), and a timer function (when the power supply is shut down for a long period of time) No connection is made to the room temperature sensor for heating control or the surface temperature sensor on the surface in contact with the human body.

It can be seen that the heating controller only controls the injection time of the simple power consumption without using the temperature and heat amount information to control the heating device.

 On the other hand, smart plugs have been popular recently. According to the IT Glossary (Korea Information and Communications Technology Association), "Smart Plug" adds functions such as Wi-Fi and smart phone to existing electric plug to turn on / off electricity remotely, can do. Therefore, it is possible to suppress the electric overheating of the home or office where the smart plug is installed or the use of unnecessary electricity. There are external plugs that can measure electricity and communication, and built-in plugs that are built into household appliances such as air conditioners, refrigerators, and televisions. From 2014, the government has defined energy-efficient first-class certification for electronic products such as air conditioners, refrigerators, and televisions that incorporate smart plug functions. "

By using such a smart plug, it is possible to control the on / off power of the electric heating product wirelessly from the remote, and to perform the functions such as analysis of electricity consumption, confirmation of use time and shutdown, and operation scheduling.

However, such a conventional smart plug has a problem that it does not use the room temperature sensor and the surface temperature sensor because it realizes simple power ON / OFF function at the remote place, electricity consumption analysis and operation scheduling function only.

The human body contact heating device 210 controls the surface temperature by adjusting the amount of power input in each set-up step.

In addition, since the human body contact heating device 210 can raise the room temperature in addition to the surface temperature, the temperature can be adjusted in the smart plug 400 when the temperature rises above the proper temperature.

 Also, the human body contact heating device 210 may be provided with a heating controller 211 between the plug 300 and the smart plug 400 before being coupled to the smart plug 400. Since the heating controller 211 has a function for preventing overheating of components and includes a timer function and the like, the heating controller 211 does not use temperature and heat amount information for controlling the heating device 200, It can be seen that only the injection time control is performed.

Since the human-body non-contact heating device 220 is formed of at least one of a radiator and a convector, it is possible to comfortably control the indoor heating without contacting the human body with radiant heat.

The setting unit 430 may set the set temperature to shut off the power when the surface temperature of the human-body contact heating unit 210 increases by a predetermined amount or when the room temperature rises by a predetermined amount or more through the human-body non-contact heating unit 220 .

The setting unit 430 may measure the set temperature by providing a separate operating device.

The setting unit 430 may include a cutoff unit 450 that cuts off the power of the heating device 200 when the room temperature rises according to the temperature generated in the heating device 200, .
