Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs. Accordingly, the shape of each element shown in the drawings may be exaggerated to emphasize a clearer description.

1 is a view schematically showing an electrothermal ventilator according to an embodiment of the present invention. As shown in Fig. 1, the electrothermal ventilator includes an enthalpy heat exchanger 1, a supply duct 6, and an exhaust duct 7. The total enthalpy heat exchanger (1) has a casing having an internal space, an inlet duct (4), and an outlet duct (5). The inlet duct 4 and the outlet duct 5 communicate with the inner space of the total enthalpy heat exchanger 1 and the outside air flows into the inner space through the inlet duct 4 and is supplied to the indoor space, The air flows into the inner space and then flows out to the outside through the outflow duct (5). Although not shown in FIG. 1, the outer space and the indoor space of the indoor space are isolated from each other, so that the outdoor space and the indoor space are not mixed with each other.

The supply fan 2 and the discharge fan 3 are installed in the inner space of the casing and the supply fan 2 forcibly sucks the outside air through the inflow duct 4 and supplies it to the supply duct 6 And the discharge fan 3 forcibly sucks the indoor air through the discharge duct 7 and forcibly discharges the air through the outlet duct 5 to be described later. 1, a heating member (for example, a heating coil) or a cooling member (for example, a cooling coil) may be installed on a path along which the external air moves in the internal space, The cooling member can adjust the temperature of the outside air by heating or cooling the outside air. That is, the heated or cooled outside air can be supplied to the supply duct 6.

The supply duct (6) communicates with the inflow duct (4) and branches. The indoor space includes space 1 (ROOM-1) to space 4 (ROOM-4), and each space can be separated from each other and separated. The ends of the supply ducts (6) are arranged in each space to supply outside air to each space. Likewise, the discharge duct 7 branches in communication with the discharge duct 5, and the end of the discharge duct 7 is disposed in each space to suck indoor air from each space.

The diffuser 100 may be installed at the ends of the supply duct 6 and the discharge duct 7, respectively. The diffuser 100 may control the flow rate of the outside air supplied through the supply duct 6 or the flow rate of the room air sucked through the discharge duct 7. [ The diffuser 100 may be electrically connected to the main controller 12. [ A detailed description of the diffuser 100 and the main controller 12 will be given later.

FIG. 2 is a side view showing the diffuser shown in FIG. 1, and FIG. 3 is a block diagram showing the main controller and the diffuser shown in FIG. As shown in FIG. 2, the diffuser 100 may be installed at the end of the supply duct 6. Although the diffuser 100 is installed in the supply duct 6 in the following description, the diffuser 100 may be installed at the end of the discharge duct 7, and the structure and function of the diffuser 100 are not limited to the installation position The diffuser 100 provided at the end of the discharge duct 7 differs in that the flow rate of the indoor air flowing into the discharge duct 7 is controlled.

The diffuser (100) has a main body (30) and an opening / closing cone (40). The main body 30 has an opening 31 communicating with the inside of the supply duct 6. The main body 30 is mounted to the air supply hole 11 formed in the ceiling 10 of each space. The opening and closing cone 40 is provided in the opening 31 of the main body 30 to adjust the flow rate of the outside air supplied through the opening 31. The opening / closing cone 40 can be moved up and down with respect to the main body 30 shown in FIG. 2, and has a cone shape in which the sectional area increases toward the bottom. Accordingly, as the open / close cone 40 moves up and down, the space in which the outside air can move increases, and the flow rate of the outside air can increase.

The bracket 60 is fixed to the inner wall of the main body 30, and the drive motor 50 is fixed by the bracket 60. The drive motor 50 has a motor shaft 51. The support base 70 is fixed to a lower portion of the bracket 60 and the motor shaft 51 is received through a feed groove 71 formed in a vertical direction on the support base 70. The support table 70 also has a movement slot 72 formed at one side of the feed groove 71. The nut 80 has a guide protrusion 81 and a fastening groove 82 and the guide protrusion 81 protrudes from the outer circumferential surface of the nut 80 and is inserted into the movement slot 72. The guide protrusion 81 is movable up and down along the movement slot 72. The engaging groove 82 is recessed from the upper surface facing the bracket 60 and the motor shaft 51 is inserted into the engaging groove 82. Since the outer circumferential surface of the motor shaft 51 and the inner circumferential surface of the fastening groove 82 are formed with threads, the motor shaft 51 is inserted into the fastening groove 82 and screwed thereto. Accordingly, when the driving motor 50 is driven, the motor shaft 51 rotates. As a result, the nut 80 is inserted vertically into the movable slot 72, The opening / closing cone 40 is also connected to the nut 80 and moves up and down together. In a state in which the opening / closing cone 40 is in close contact with the main body 30, the opening 31 is closed to block the movement of outside air.

3, the diffuser 100 includes a control unit 54 for controlling the driving motor 50, a receiving unit 52 for transmitting a control signal to the control unit 54, (Not shown). The receiving unit 52 receives the control signal transmitted from the outside by the user in a wireless or wired manner, and transmits the control signal to the control unit 54. For example, the user can increase or decrease the supply amount of outside air by raising or lowering the opening / closing cone 40 by transmitting a control signal through a wireless remote controller (for example, a wireless remote controller using IR). At this time, the receiving unit 52 may receive the control signal transmitted from the user and transmit the control signal to the control unit 54. Upon receiving the control signal, the control unit 54 supplies power to the driving motor 50 in accordance with the control signal, thereby raising or lowering the opening / closing cone 40. The driving motor 50 can raise or lower the opening / closing cone 40 in accordance with the rotating direction.

Meanwhile, the control unit 54 may have an automatic mode that operates according to the state value in the space, in addition to the manual mode operated according to the control signal of the user as described above. That is, the sensing unit 56 senses the temperature in the space and transmits it to the control unit 54. When the temperature in the space is out of the predetermined temperature range, the control unit 54 controls the driving motor 50 So that the opening / closing cone 40 can be raised or lowered. The state value may be a temperature or an indoor pollution degree, and the sensing unit 56 may be a temperature sensor or a pollution degree measuring sensor (for example, a concentration sensor of CO2).

For example, when the outside air is heated and supplied through the heating coil as described above and heated, if the temperature in the space exceeds the predetermined temperature range, the control unit 54 raises the opening / closing cone 40 Thereby reducing or blocking the supply of heated outside air. The predetermined temperature can be input by the wireless remote controller through the user. Further, when the temperature in the space is lower than the predetermined temperature, the control unit 54 can lower the open / close cone 40 to increase the supply of the heated outside air.

It is preferable that the control unit 54 operates in the manual mode when the control signal of the user is received through the receiving unit 52 in the state of operating in the automatic mode. That is, the controller 54 operates in the manual mode to drive the driving motor 50 according to the control signal, in order to provide an optimal indoor environment according to the user's tendency.

When the drive motor 50 is raised or lowered, the control unit 54 controls the opening / closing cone 40 via the status indicator lamp 58 provided on the lower surface of the main body 30 or the lower surface of the open / Can be displayed. That is, the status display lamp 58 may have a plurality of lamps (for example, up / down / down) and supply power to any one of the lamps according to the state of the open / 40 can be displayed. As described above, the diffuser 100 is installed in the ceiling 10 and it is difficult for the user to accurately check the state of the opening / closing cone 40. [ Or status display lamp 58 can display the state of opening / closing 40 in a different color (for example, red / yellow / green).

On the other hand, the control unit 54 can drive the drive motor 50 through the operation signal received from the main controller 12. [ That is, the sensing unit 56 senses the temperature in the space and transmits it to the main controller 12 instead of the controller 54. When the temperature in the space is out of the predetermined temperature range, the main controller 12 And the control unit 54 may supply power to the driving motor 50 in accordance with the operation signal to raise or lower the opening / closing cone 40. [ In this case, the sensing unit 56 may not transmit the temperature in the sensed space to the control unit 54. [

On the other hand, the supply fan 2 and the discharge fan 3 are electrically connected to the main controller 12, and the main controller 12 drives the supply fan 2 And the operation speed of the discharge fan 3 can be adjusted. That is, the main controller 12 can increase or decrease the operation speed of the supply fan 2 and the discharge fan 3 when the temperature in the space exceeds or falls within a predetermined temperature range, thereby keeping the state in the space pleasant . However, since the supply fan 2 and the discharge fan 3 are applied to the entire indoor space, it is difficult to perform optimal control according to the state of each space, and each space can be optimally controlled by raising and lowering the opening / closing cone 40 . Similarly, the heating coils and the cooling coils previously described are also controlled through the main controller 12, so that the heating speed or the cooling speed can be adjusted by the main controller 12. [

4 is a block diagram showing another embodiment of the main controller and the diffuser shown in FIG. Although it has been described above that the diffuser 100 includes the control unit 54, as shown in Fig. 4, the control unit 54 may be omitted.

As shown in Fig. 4, the receiving unit 52 receives the control signal transmitted from the outside by the user in a wireless or wired manner, and transmits the control signal to the main controller 12. For example, the user can increase or decrease the supply amount of outside air by raising or lowering the opening / closing cone 40 by transmitting a control signal through a wireless remote controller (for example, a wireless remote controller using IR). At this time, the receiving unit 52 may receive the control signal transmitted from the user and transmit the received control signal to the main controller 12. When the main controller 12 receives the control signal, the main controller 12 supplies power to the driving motor 50 in accordance with the control signal, thereby raising or lowering the opening / closing cone 40. The driving motor 50 can raise or lower the opening / closing cone 40 in accordance with the rotating direction.

In addition to the manual mode in which the main controller 12 operates in accordance with the user's control signal in connection with the operation of the drive motor 50, it can have an automatic mode that operates according to the state value in the space. That is, the sensing unit 56 senses the temperature in the space and transmits it to the main controller 12. When the temperature in the space is out of the predetermined temperature range, The open / close cone 40 can be raised or lowered by supplying power to the power source 50. The state value may be a temperature or an indoor pollution degree and the sensing unit 56 may be a temperature sensor or a concentration sensor such as a concentration of volatile organic chemicals (VOCs), floating dust, carbon monoxide (CO), carbon dioxide Sensor).

For example, when the outside air is heated and supplied through the heating coil as described above and heated, if the temperature in the space exceeds a preset temperature range, the main controller 12 controls the opening / closing cone 40 Thereby reducing or blocking the supply of heated external air. The predetermined temperature can be input by the wireless remote controller through the user. Further, when the temperature in the space is lower than the predetermined temperature, the control unit 54 can lower the open / close cone 40 to increase the supply of the heated outside air.

However, it is preferable that the main controller 12 operates in the manual mode when the control signal of the user is received through the receiver 52 while the main controller 12 operates in the automatic mode. That is, in order to provide an optimal indoor environment according to the user's tendency, the main controller 12 operates in the passive mode and can drive the driving motor 50 according to the control signal.

When the drive motor 50 is raised or lowered, the main controller 12 controls the operation of the open / close cone 40 (not shown) through the status indicator lamp 58 provided on the lower surface of the main body 30 or the lower surface of the open / ) Can be displayed. That is, the status display lamp 58 may have a plurality of lamps (for example, up / down / down) and supply power to any one of the lamps according to the state of the open / 40 can be displayed. As described above, the diffuser 100 is installed in the ceiling 10 and it is difficult for the user to accurately check the state of the opening / closing cone 40. [ Or status display lamp 58 can display the state of opening / closing 40 in a different color (for example, red / yellow / green).

Although the sensing unit 56 is a temperature sensor, the sensing unit 56 may be a pollution measuring sensor. That is, when the pollution degree is over or below a predetermined range, the amount of ventilation can be controlled by increasing or decreasing the flow rate of the outside air and the room air supplied / discharged through the diffuser 100 by lowering or raising the open / close cone 40.
