Fluid apparatus

Abstract

A fluid aparatus includes an apparatus main body that includes a motor and a fan driven by the motor, a frame on which the apparatus main body is mounted, a pipe that is detachably attached to the apparatus main body to discharge and introduce a fluid by rotation of the fan, an operation unit that is provided to the pipe to input an operation command for the apparatus main body by operation from outside, a cable that transmits a signal between the operation unit and the apparatus main body, and a connecting portion that is provided to the cable to separably couple the operation unit and the apparatus main body to each other.

What is claimed is: 
     
         1 . A fluid apparatus comprising:
 an apparatus main body that comprises a motor and a fan driven by the motor;   a frame on which the apparatus main body is mounted;   a pipe that is detachably attached to the apparatus main body to discharge and introduce a fluid by rotation of the fan;   an operation unit that is provided to the pipe to input an operation command for the apparatus main body by operation from outside;   a cable that transmits a signal between the operation unit and the apparatus main body; and   a connecting portion that is provided to the cable to separably couple the operation unit and the apparatus main body to each other.   
     
     
         2 . The fluid apparatus according to  claim 1 , wherein the connecting portion is provided to at least one of a connection between the cable and the operation unit or a connection between the cable and the apparatus main body. 
     
     
         3 . The fluid apparatus according to  claim 1 , wherein the connecting portion is provided to an intermediate portion of the cable. 
     
     
         4 . The fluid apparatus according to  claim 1 , wherein the operation unit comprises a plurality of input elements that inputs a plurality of commands. 
     
     
         5 . The fluid apparatus according to  claim 4 , wherein the operation unit comprises a dial switch that sets a maximum rotational speed of the motor, a trigger switch that inputs a speed command for the motor according to an amount the trigger switch is operated, and a lock button that locks an operational position of the trigger switch as the plurality of input elements. 
     
     
         6 . The fluid apparatus according to  claim 4 , wherein the operation unit comprises a main power switch for the apparatus main body as one of the plurality of input elements.  7 , The fluid apparatus according to  claim 1 ,
 wherein the apparatus main body comprises a plurality of motors, and   wherein the operation unit is configured to input a command value common to each of the plurality of motors as an operation command for the plurality of motors.   
     
     
         8 . The fluid apparatus according to  claim 1 ,
 wherein the operation unit comprises a display that displays conditions of the apparatus main body.   
     
     
         9 . The fluid apparatus according to  claim 8 ,
 wherein the display is configured to display at least one of a run/stop state of the apparatus main body, remaining energy of a battery supplying electric power to the motor, or an abnormality in the apparatus main body.   
     
     
         10 . The fluid apparatus according to  claim 1 ,
 wherein the operation unit is provided to the pipe position-adjustably along a central axis of the pipe.   
     
     
         11 . The fluid apparatus according to claim I,
 wherein the operation unit is detachably attachable to the pipe.   
     
     
         12 . The fluid apparatus according to  claim 1 , comprising a backpack fluid apparatus.
