`
`What is claimed is,
`
`1. A ventilating device, comprising:
`
`a frame formed with an external profile;
`
`an air inlet provided in the frame;
`
`an air outlet provided in the frame;
`
`an air blower for guiding air from the air inlet to the air outlet;
`
`a control circuit board connected to the air blower and configured to control operation of
`
`the air blower; and
`
`a circuit board box for housing the control circuit board;
`
`wherein the circuit board box comprises an integrally formed sensor storage unit for
`
`storing a sensor connected to the control circuit board and capable of sensing humidity or
`
`temperature.
`
`2. The ventilating device according to claim 1, further comprising:
`
`a terminal connected to the air blower and provided on the control circuit board, the
`
`control circuit board and a lead of the air blower being connected to each other through the
`
`terminal; and
`
`an operation opening provided in the circuit board box and opposite to the terminal.
`
`3. The ventilating device according to claim 2, further comprising:
`
`
`
`CSPT—153US
`
`PATENT
`
`21
`
`a cover for covering the operation opening; and
`
`an insertion opening for guiding the lead to the circuit board box.
`
`4. The ventilating device according to claim 1, wherein the air blower comprises:
`
`a motor;
`
`a first air suction port provided proximate to the motor;
`
`a second air suction port opposite to the first air suction port;
`
`an air discharge port for discharging air from the air blower; and
`
`a fan configured to guide air from the first air suction port and the second air suction
`
`port into the air blower and discharge the air from the air blower via the air discharge port
`
`simultaneously.
`
`5. The ventilating device according to claim 4, wherein the frame comprises:
`
`a first side surface provided with the air inlet;
`
`a second side surface opposite to the first side surface and provided with the air outlet
`
`corresponding to the air discharge port;
`
`a top surface adjacent to the first side surface and facing the first air suction port;
`
`a bottom face adjacent to the first side surface and facing the second air suction port;
`
`and
`
`a third side surface and a fourth side surface that are adjacent to the top surface and
`
`
`
`CSPT—153US
`
`PATENT
`
`22
`
`the bottom surface, respectively;
`
`wherein, the circuit board box is provided between the third side surface and the air
`
`blower or between the fourth side surface and the air blower.
`
`6. The ventilating device according to claim 5, further comprising:
`
`a first air path for communicating the air inlet with the first air suction port; and
`
`a second air path for communicating the air inlet with the second air suction port;
`
`wherein a distance from the first air suction port to the top surface is greater than a
`
`distance from the second air suction port to the bottom surface, and the sensor storage unit
`
`is provided at a second air path side.
`
`7. The ventilating device according to claim 1, wherein the sensor storage unit is
`
`provided with an air entrance port provided in a face of the sensor storage unit facing the
`
`air inlet and configured to guide the air into the sensor storage unit.
`
`8. The ventilating device according to claim 7, wherein a first end of the sensor storage
`
`unit is provided on a wall of the circuit board box, and a second end of the sensor storage
`
`unit extends outwards from the circuit board box.
`
`9. The ventilating device according to claim 8, wherein the air entrance port is provided
`
`at the second end.
