Ventilation apparatus and a garment on which the ventilation apparatus can be mounted

Abstract

A ventilation apparatus is mountable on a garment, such as a jacket. The ventilation apparatus includes a fan that is rotationally driven by a motor and is housed in a main body that includes intake ports and exhaust ports. The motor may be a brushless motor. In addition or in the alternative, a main body of the motor may be shorter than blades of a fan mounted on a drive shaft of the motor.

 a filter-condition-detecting part configured to detect whether or not a threshold has been exceeded indicating that dust has accumulated on or in the filter.   
     
     
         7 . The ventilation apparatus according to  claim 5 , further comprising:
 a dust-removing part configured to remove, from the filter, dust that has accumulated on or in the filter.   
     
     
         8 . The ventilation apparatus according to  claim 1 , further comprising:
 a Peltier element.   
     
     
         9 . The ventilation apparatus according to  claim 1 , further comprising:
 a battery for driving the motor.   
     
     
         10 . The ventilation apparatus according to  claim 1 , wherein:
 the intake ports comprise:
 a first intake port that opens in an output-shaft direction of the drive shaft; and 
 a second intake port that opens in a direction that intersects the drive shaft. 
   
     
     
         11 . A garment having the ventilation apparatus according to  claim 1  mounted thereon. 
     
     
         12 . The ventilation apparatus according to  claim 1 , wherein the motor is a brushless motor. 
     
     
         13 . The ventilation apparatus according to  claim 12 , wherein a filter is either (i) housed in the housing between the intake ports and the exhaust ports or (ii) mounted on an exterior side of the intake ports. 
     
     
         14 . The ventilation apparatus according to  claim 13 , further comprising:
 a filter-condition-detecting part configured to detect whether or not a threshold has been exceeded indicating that dust has accumulated on or in the filter.   
     
     
         15 . The ventilation apparatus according to  claim 14 , further comprising:
 means for removing, from the filter, dust that has accumulated on or in the filter.   
     
     
         16 . The ventilation apparatus according to  claim 15 , further comprising:
 a Peltier element in an airflow path between the inlet ports and the exhaust ports; and   a rechargeable battery detachably attached to a battery receiving part in electrical communication with the motor.   
     
     
         17 . The ventilation apparatus according to  claim 16 , wherein the intake ports comprise:
 a first intake port that opens in an output-shaft direction of the drive shaft; and   a second intake port that opens in a direction that intersects the drive shaft.   
     
     
         18 . The ventilation apparatus according to  claim 17 , wherein:
 the motor comprises a main body, which has a stator and a rotor, and a drive shaft;   the fan comprises blades mounted on the drive shaft; and   the main body is shorter than the blades in the output-shaft direction of the drive shaft.   
     
     
         19 . The ventilation apparatus according to  claim 18 , further comprising:
 a temperature sensor;   a temperature-information-based control part configured to control the rotational speed of the motor based on temperature information from the temperature sensor;   a receiver configured to receive biological information of a user sent by a mobile computer; and   a biological-information-based control part configured to control the rotational speed of the motor based on the biological information from the receiver.
