Further, the wall surface of the room is provided with natural air intakes 21 for taking in the air of outside air (the number of natural air intakes is set as many as the number of the room), and the outside air is sucked into the room and exhausted to the outside.

  The configuration of the control circuit 22 includes a power supply circuit (for example, an AC-DC converter), a motor drive circuit (not shown), a vibration detection unit 23 that detects vibration of the motor, and a temperature detection unit 24 that detects the temperature inside the control circuit 22. And a control unit (not shown, for example, a microcomputer). The microcomputer has a series of operations based on the value detected by the vibration detecting means 23 and the value detected by the temperature detecting means 24. Possible programs are written. The mounting position of the control circuit 22 is disposed in the vicinity of the motor, and the vibration detecting means 23 is disposed on the substrate and is disposed in a portion where the substrate is not bent for manufacturing. It is configured to cover with resin or metal so as not to be affected.

  Further, the configuration of the vibration detecting means 23 uses, for example, an acceleration sensor (shock sensor). An acceleration sensor) generates electric charge in proportion to acceleration applied from the outside.

  For example, a differential pressure sensor is used as the configuration of the differential pressure detection means 29. The differential pressure sensor has a target structure in which the pressure receiving surface is a silicon diaphragm. When the pressure is received, the diaphragm fluctuates and the capacitance changes, so that the change in capacitance is electrically output.

  Further, the ends of the HIGH side pressure introduction port 30 and the LOW side pressure introduction port 32 (for example, a silicon tube) are arranged at a position (not shown) on the inner wall surface of the exhaust duct connection port 18.

  Further, a DC motor is provided for the motor 15 of the first embodiment. For example, a DC motor is generally a direct current motor 15 that can be driven by a direct current power source. The DC motor has very excellent characteristics as a control motor. .

  In addition, the display portion 33 is provided at the center of the louver 16 on the lower surface of the main body 4, and the display portion 33 is configured by an LED and a switch, and the display content is a display that prompts the ventilator user to clean. The display portion 33 is composed of two types of displays for prompting the ventilator user that the ventilator has stopped and a switch for notifying the control circuit 22 that the ventilator user has cleaned the ventilator.

  For example, the LED that prompts cleaning is blue, and the LED that prompts the ventilation device to stop is red.

  An LED is a diode that emits light, and is a semiconductor element that has a PN junction of a semiconductor and is turned on when energy generated when a current in a certain direction flows is turned into light.

  Further, the control circuit 22 is provided with an integration means 34 (not shown) for integrating the energization time of the fan.

  The configuration of the integrating means 34 uses, for example, a microcomputer. Further, the integrating means 34 is provided with a storage means for storing the time accumulated by the integrating means 34 in the event of a power failure. The storage means is configured to use, for example, an EEPROM.

  An EEPROM is a type of memory, and is a semiconductor memory device that can erase and rewrite data by operating a voltage.

  In the above configuration, the operation of the ventilator will be described with reference to the flowchart shown in FIG. Note that description of operations similar to those of the first embodiment is omitted.

  For example, when the power switch 25 is turned on to the ventilator so that the ventilator user operates the ventilator, power is applied to the control circuit 22. When power is applied to the control circuit 22, power is generated by a power supply circuit (for example, an AC-DC converter), and a program incorporated in the microcomputer starts processing, and vibration detection means 23, temperature detection means 24, differential pressure Reading of the detection means 29, the human measurement device 26, and the integrating means 34 is started, and as shown in the flowchart of FIG. 6, the integrating means 34 starts integrating the energization time of the fan simultaneously with the rotation of the fan. Since 1 minute and 30 seconds have elapsed as the time until the human measurement device 26 is stabilized, and when a person enters the room toilet, the room and toilet doors are opened, so the pressure inside the room and inside the toilet changes. To do. When the pressure inside the living room or the toilet changes, the differential pressure detection means 29 detects the change in pressure. When a change in pressure is detected, whether or not the air volume increases depends on the situation of the room, but when the pressure changes, the ventilation device tries to secure the same air volume, so the rotational speed of the DC motor also changes. When the number of rotations of the DC motor changes, the vibration detection unit 23 detects vibration, and when the vibration determination unit 27 determines that the vibration exceeds the determination value, the vibration due to pressure fluctuation in the living room or the toilet Judge and keep the current situation.

  In addition, when the pressure inside the room or the toilet changes, the ventilator tries to secure the same air volume, so that, for example, the rotational speed of the DC motor is increased and the air volume is stabilized. When the air volume is stable and the rotational speed of the DC motor is stable, if the vibration is detected by the vibration detecting means 23 and the vibration determining means 27 determines that the vibration is large, the resonance of the housing of the ventilator and the DC motor It is determined that the vibration is composed of a point, and until the vibration is reduced by the vibration determination means 27, the rotational speed of the DC motor is further increased, the resonance point is shifted, the air volume is secured, and the vibration due to the resonance point is reduced.

  Further, it is determined that the vibration detecting means 23 detects vibration even though the integrating means 34 for integrating the energization time has not reached the preset time, and exceeds the value set in advance by the vibration detecting means 23. In this case, it is determined that dust is attached to the fan, the fan load is increased, and vibration has occurred, and the ventilation sign user turns on the cleaning sign LED blue on the display portion 33. The fan shall keep the current state. After a certain period of time (for example, for a week), if the ventilation sign user does not clean up even though the cleaning sign is lit, it is judged that the vibration will be further increased and the ventilation system is stopped and the ventilation system is used. The person turns on the fan stop sign LED in the display portion 33 in red.

  When the ventilator user performs cleaning, the ventilator user presses a switch (not shown) in the display portion 33, and the cleaning sign is turned off. When the accumulated time 34 reaches a preset time, it is determined that the life of the DC motor has been reached regardless of whether the vibration detecting means 23 has been detected or not, and the DC motor is stopped, and the display portion is displayed to the ventilator user. The fan stop sign LED at 33 is lit in red.

  The ventilator configured as described above can urge the ventilator user to clean the fan when dust adheres to it and vibrations can be eliminated. In addition, vibration of the resonance point of the fan that occurs when the door is opened or closed can be prevented.

  In addition, since the motor energization time can be integrated, it can be determined whether vibration has occurred during the life of the motor or whether it has occurred due to insufficient cleaning. It can be provided to the device user.

(Embodiment 3)
A third embodiment will be described with reference to FIG. Note that description of the same components as those in the first embodiment is omitted.

  The louver 16 on the lower surface of the main body 4 includes a filter 35 that prevents dust from adhering to the blades.

  In the above configuration, the operation of the ventilator will be described with reference to the flowchart shown in FIG. Note that description of operations similar to those of the second embodiment is omitted.

  When a person enters the room or toilet, the room and toilet doors are opened, so the pressure inside the room and inside the toilet changes. When the pressure inside the living room or the toilet changes, the differential pressure detection means 29 detects the change in pressure. When a change in pressure is detected, whether or not the air volume increases depends on the situation of the room, but when the pressure changes, the ventilation device tries to secure the same air volume, so the rotational speed of the DC motor also changes.

  If there is no change in the differential pressure in the differential pressure detection means 29, the vibration detection means 23 detects vibration, and if the vibration determination means 27 exceeds the determination value, dust adheres to the filter 35 and the pressure is applied to the fan. It is determined that vibration has occurred due to a change in the rotation speed of the fan, and the cause of the vibration is determined that the filter is clogged, and the ventilation sign user turns on the cleaning sign LED blue on the display portion 33 Will be allowed to.

  A ventilator attached to a building according to the present invention is widely useful in products that prevent motor accidents and accidents due to secular change by judging the life of a motor and a failure of a load drive element from vibrations of the ventilator.
