Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a temperature control device, and more particularly, to a temperature control device for automatically controlling a household environment capable of reducing energy (cooling and heating costs) and user convenience and performing a remote control operation without self-learning.

The cost of heating and cooling generated in each household such as a general house or an apartment complex can be saved even if household members care a little. Research has shown that power consumption can be reduced by 2 to 5% even if the temperature is changed by only 1 ° C at the set temperature.

However, since the temperature change or control is largely dependent on manual operation, it is inconvenient to use and it has been difficult to control the optimum energy.

On the other hand, a self-learning type thermostat which self-learns and adjusts the temperature without manual operation is known as a learning (cognitive) thermostat device developed by Nestlap Co., for example.

Here, the user manually adjusts the temperature manually in the first week of installation in the same manner as other thermostats. Then, based on the experience of the learning, the temperature control device recognizes the user's most preferred room temperature. For example, if family members warm up at 7 am and turn off the heater when they leave home to go to work or school, the thermostat recognizes these habits after the lessons are finished. In automatic mode, Automatically.

In the case of such thermostats, a learning period is required, and during the learning period, the user must manually manipulate the operation. If you do not carefully manipulate manual operations during the learning period, you can ruin your energy management rather than learn it. Furthermore, if the life pattern suddenly changes due to the user's vacation or the like, the temperature control according to the learning so far may be difficult to provide the optimal control.

Furthermore, it is difficult to say that temperature control is accurate because it is not to automatically determine the household environment by accurately determining the household environment by switching the temperature control mode to the sleep mode, depending on whether the person is indoors and sleeping alone.

And, in the automatic adjustment mode, it is not preferable from the viewpoint of energy saving to instantly change from one operation mode to another operation mode. For example, if the user goes out for a while and returns home, the heating temperature control may immediately start operating in the outgoing mode without checking the time, or immediately returning to the normal operation in the outgoing mode may waste energy have.

In addition, it has been difficult to perform the remote control mode more effectively in conjunction with a portable terminal such as a smart phone.

If it is determined in step S121 that a returning condition is satisfied, it is checked in step S122 whether the mode is the automatic control mode.

In the automatic control mode, the current temperature, illuminance, body, light, weather, and season information are read in step S122, and it is determined whether the normal or power saving condition is satisfied in step S124.

If the normal or power-saving condition has been met, a light switch on / off control signal for light switch on / off control may be applied to the light switch driver 123 in step S125.

In step S126, the temperature control data of the normal or power saving condition at the time of return judgment can be transmitted step by step according to the time interval as shown in FIG.

On the other hand, in the case of the carbon dioxide concentration, the upper limit is set to be 1200 ppm or more.

For example, when an operating condition for raising the temperature of the initial temperature 60 by 70 degrees occurs, the temperature may be raised in three steps. The first step of raising 62 degrees is performed for 10 minutes. Also, the second stage of raising to 66 degrees runs for 20 minutes. Finally, the third step of raising to 70 degrees runs for 30 minutes. This step-by-step temperature control eliminates energy wastage due to sudden temperature transitions and thus provides optimal energy savings.
