FIG. 1 is a perspective view of an automatic control apparatus for temperature and humidity control according to a preferred embodiment of the present invention, and FIG. 2 is a perspective view and a use state view of a heating element according to the present invention.

1, an automatic switchboard temperature / humidity control apparatus for automatically controlling an internal temperature and a humidity of an ASSEMBLY includes a frame 10 having a rectangular internal space for accommodating an electric circuit, A measuring device 20 including a temperature sensor for detecting a temperature and an outside temperature and a humidity sensor for detecting humidity generated in the inside of the switchgear, A main controller 30 for automatically collecting the temperature and humidity inside the cabin in comparison with the main controller 30, a heating unit 40 for generating heat in accordance with instructions from the main controller, And an air blower 50 for discharging the air to the outside.

The temperature sensor 21 is provided at two places on the left and right side walls of the frame. One of the two sensors senses the internal temperature of the frame 10, One senses the external temperature.

A humidity sensor 22 capable of detecting humidity generated due to a deviation between an external temperature and an internal temperature of the frame is disposed at a lower end portion of the left and right side walls of the frame 10 provided with the temperature sensor 21, More than one is installed.

For example, since the temperature sensor is installed at the upper end of the frame 10 because the high temperature air current is moved from the lower part to the upper part, and the humidity is moved from the upper part to the lower part, However, the present invention is not limited to this, and it is natural that a plurality of frames are provided at various positions so that the temperature and humidity inside the frame can be measured more accurately and easily.

Meanwhile, the main controller 30 generally controls and manages temperature and humidity inside the switchboard.

Before describing the main controller 30, there are two methods for sensing and controlling the internal temperature and humidity of the switchboard according to the present invention. Firstly, by using the measuring device 20, A method of always maintaining a temperature close to the inside of the cabinet by measuring an average value of the temperature of the cabinet, and a method of maintaining the proper temperature by inputting a desired temperature directly to the main controller by the user.

Accordingly, the measuring device 20 is always in communication with the main controller 30. In order for the user to directly input a desired temperature to the main controller, the main controller controls the keypad and the measurement information and input information to be visually checked It is equipped with a display that can be.

As shown in FIG. 3, the display of the main controller 30 transmits the same data to a user's smartphone or a computer, thereby controlling the internal environment of the power distribution board remotely in various spaces without regard to the working position and environment .

The heating line 42 is integrally formed so as to pivot on three inner sides of the frame 10 and is opened toward the inner side of the frame 10, A cover T is formed and a flange S formed at the upper and lower ends of the cover T and attached to the inner three surfaces of the frame 10 is formed. Therefore, it can easily correspond to the inner three sides of the frame 10. Further, formed on the cover (T) the heating element (41) is binary and arranged along the cover (T) to be able to deliver effectively the internal space of the heat dissipating frame 10 inclined in an oblique direction slow Trojan formed a plurality of vent (44). The air heated by the vent hole 44 is discharged while rotating in a spiral manner, so that the load of the ventilator 50 is reduced. That is, since the heated air is discharged while swirling in the form of a spiral by the inclined slit-shaped vent hole 44, the load for forcibly rotating the heated air by the ventilator 50 is reduced, thereby saving energy .
The fixing ring 43 has a C-shaped clamping portion P accommodated inside the cover T and opened toward the inner side of the frame 10 to receive the heating element 41, A connecting portion Q of the -type connected to the clamping portion P and fixed to the inner surface of the cover T is constructed. The connecting portion (Q) is configured such that the length of the heating element (41) is spaced apart from the inner surface of the frame (10). Therefore, it is possible to prevent the heat generating element 41 from contacting the frame 10, thereby preventing the heat of the heat generating element 41 from being radiated through the frame 10.
Particularly, the heating element of the heating unit 40 uses a PTC heating wire. When the temperature of the PTC heating wire is raised to an appropriate temperature or higher, the amount of the current is reduced to maintain the proper temperature at all times. More specifically, As the resistance increases, the amount of current decreases to lower the temperature. When the temperature decreases, the resistance decreases. As the amount of current increases, the heat starts again. This reduces power consumption and there is no risk of fire due to high temperature.

As described above, the initial temperature setting step (S10) includes an appropriate temperature / humidity manual setting method (S11) in which the user inputs an appropriate temperature and an appropriate humidity using the keypad of the main controller, And an external temperature / humidity comparison measurement method (S12) for automatically inputting the average temperature and humidity to the main controller can be selectively used.

Also, in the main controller processing step S30 for receiving and comparing the data sensed by the inside / outside temperature / humidity sensing step S20 of the switchboard, the controller 30 compares and analyzes the initial set temperature and humidity, 50, the optimum temperature is 35 ° C. When the internal temperature of the switchboard rises above the optimum temperature of 35 ° C, the ventilator 50 is driven and the high temperature air Discharge to the outside of the switchboard.

On the other hand, if the humidity inside the switchboard increases by more than 50%, there will be a short circuit between the insulators of the circuit breaker, and a short circuit may occur. In such a case, a fire may occur. For this reason, a PTC heating element The humidity sensor transmits the humidity measurement value to the main controller, and the main controller compares the initial setting value with the current measurement value and transmits the operation result to the heating unit 40, And controls the generated humidity.

Particularly, the measuring device 20 measures the current temperature and humidity of the cabin, and the process information of the main controller 30 and the driving information of the heating unit 40 and the ventilator 50, And the ventilator drive to display the current temperature and humidity change status inside the switchboard in real time on the main controller as well as to the user's smartphone or computer and control the main controller remotely And is provided so as not to be inconsistent with the user's work place.

According to the present invention having the above-described structure, since the main controller senses not only the internal space of the switchboard but also the external temperature, the main controller automatically adjusts the temperature, so that the internal space of the switchboard can easily The user can directly control the internal temperature of the switchboard by setting the proper temperature directly through the keypad of the main controller and receive the temperature and humidity information of the inside of the switchboard in real time on the smartphone and the computer monitor, Can be controlled instantaneously. In addition, by using the PTC heating element, when the temperature rises to an appropriate level or higher, the amount of current is reduced to maintain the proper temperature at all times. More specifically, when the temperature becomes too high, the resistance increases to decrease the amount of current, When the temperature is lowered, the resistance is lowered and the amount of current is increased to start the heat generation again. This is a low power consumption and there is no danger of fire due to high temperature.
