Sheet manufacturing apparatus and humidifying apparatus

Abstract

A sheet manufacturing apparatus includes a humidifying case and a humidified air generator attachable to and detachable from the humidifying case, the humidifying case includes a first sensor, the humidified air generator includes a water storage unit that stores water and a float unit that is displaced according to a water level of the water storage unit, and the first sensor detects that the float unit is located at a first position that is a position of the float unit in a state where the humidified air generator is set in the humidifying case and drainage of the water storage unit is completed.

What is claimed is: 
     
         1 . A sheet manufacturing apparatus comprising:
 a processing unit that defibrates a material and manufactures a sheet from obtained fibers;   a humidifying case; and   a humidified air generator that is attachable to and detachable from the humidifying case and humidifies air, wherein   the humidifying case includes a first sensor,   the humidified air generator includes a water storage unit that stores water and a float unit that is displaced according to a water level of the water storage unit, and   the first sensor detects that the float unit is located at a first position that is a position of the float unit in a state where the humidified air generator is set in the humidifying case and drainage of the water storage unit is completed.   
     
     
         2 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the humidifying case includes a water supply unit that supplies the water to the water storage unit, and   the water supply unit is controlled by a control unit included in the sheet manufacturing apparatus based on a detection result of the first sensor.   
     
     
         3 . The sheet manufacturing apparatus according to  claim 2 , wherein
 the humidifying case includes a second sensor, and   the second sensor detects that the float unit is located at a second position that is a position of the float unit in a state where the humidified air generator is set in the humidifying case and the water storage unit is full of water.   
     
     
         4 . The sheet manufacturing apparatus according to  claim 3 , wherein
 the control unit causes the water supply unit to start supplying water in response to a detection result of the second sensor indicating that the float unit is not located at the second position while the humidified air generator is performing humidification and causes the water supply unit to stop supplying water on condition that a detection result of the second sensor indicates that the float unit is located at the second position.   
     
     
         5 . The sheet manufacturing apparatus according to  claim 3 , further comprising
 a door that enables attachment and detachment of the humidified air generator in an open state and disables attachment and detachment of the humidified air generator in a closed state, wherein   the control unit causes the water supply unit to start supplying water when the detection result of the first sensor indicates that the float unit is located at the first position after the door changes from the open state to the closed state and causes the water supply unit to stop supplying water on condition that a detection result of the second sensor indicates that the float unit is located at the second position.   
     
     
         6 . The sheet manufacturing apparatus according to  claim 1 , further comprising
 a door that enables attachment and detachment of the humidified air generator in an open state and disables attachment and detachment of the humidified air generator in a closed state; and   a lock for locking and unlocking the door, wherein   the lock unlocks the door in a state where the first sensor detects that the float unit is located at the first position.   
     
     
         7 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the humidified air generator includes an inclined surface portion,   the float unit includes a floating portion, a magnet, and an arm portion,   the arm portion has a first end that is rotatably supported with respect to a shaft,   the arm portion has a second end that is provided with the floating portion and the magnet,   the floating portion generates buoyancy that causes the float unit to turn with respect to the shaft according to the water level of the water storage unit,   when the float unit is located at the first position,   the inclined surface portion abuts against the float unit to restrain turning of the float unit,   the arm portion extends from the first end to the second end in a direction toward a side where the float unit is located when the water storage unit is full of water rather than vertically downward, and   the first sensor is a magnetic sensor and detects that the float unit is located at the first position according to a magnetic field generated by the magnet.   
     
     
         8 . A humidifying apparatus comprising:
 a drive unit;   a first sensor; and   a humidified air generator attachable to and detachable from the first sensor, wherein   the humidified air generator includes a water storage unit that stores water, and   the first sensor detects a state where the humidified air generator is set and drainage of the water storage unit is completed.
