Range hood

Abstract

A range hood includes: fan unit ( 4 ) having a built-in fan; frame unit ( 3 ) connected to the fan unit; rectifier ( 5 ) disposed in a lower part of the frame unit; and communication module ( 7 ) mounted on mounting portion ( 6 ) of the frame unit. The communication module includes transmitting/receiving unit ( 11 ) and transmitting/receiving unit case ( 8 ). The communication module performs, via the transmitting/receiving unit, radio communication using radio waves with a central control unit that controls another ventilation apparatus or another air conditioning apparatus. The transmitting/receiving unit case includes case portion ( 9 ) covering the transmitting/receiving unit, and cover portion ( 10 ) connected to the case portion. The mounting portion is made of metal, has a box shape, and has opening ( 21 ) so that radio waves arrive at transmitting/receiving unit that is built-in the mounting portion. The cover portion is at least partially made of resin or glass. The cover portion is fixed to the mounting portion so as to block the opening and be exposed to the inside of a room.

What is claimed is: 
     
         1 . A range hood comprising:
 a fan unit having a built-in fan;   a frame unit connected to the fan unit;   a rectifier disposed in a lower part of the frame unit; and   a communication module mounted on a mounting portion of the frame unit,   wherein
 the communication module includes a transmitting/receiving unit and a transmitting/receiving unit case, and performs radio communication using a radio wave with a central control unit via the transmitting/receiving unit, the central control unit controlling another ventilation apparatus or another air conditioning apparatus, 
 the transmitting/receiving unit case includes a case portion covering the transmitting/receiving unit, and a cover portion connected to the case portion, 
 the mounting portion is made of metal, has a box shape, and has an opening so that the radio wave arrives at the transmitting/receiving unit that is build-in the mounting portion, and 
 the cover portion is at least partially made of resin or glass, and is fixed to the mounting portion so as to block the opening and be exposed to an inside of a room. 
   
     
     
         2 . The range hood according to  claim 1 , wherein
 the cover portion and the opening are disposed in a lower surface of the mounting portion.   
     
     
         3 . The range hood according to  claim 1 , wherein
 the cover portion and the opening are disposed in an upper surface of the mounting portion.   
     
     
         4 . The range hood according to  claim 1 , wherein
 a suction unit is formed between the rectifier and a rear surface of the mounting portion, and the cover portion and the opening are disposed in the rear surface of the mounting portion.   
     
     
         5 . A range hood comprising:
 a fan unit having a built-in fan;   a frame unit connected to the fan unit;   a rectifier disposed in a lower part of the frame unit; and   a communication module,   wherein
 the communication module includes a transmitting/receiving unit and a transmitting/receiving unit case, and performs radio communication using a radio wave with a central control unit via the transmitting/receiving unit, the central control unit controlling another ventilation apparatus or another air conditioning apparatus, and 
 the transmitting/receiving unit case is at least partially made of resin or glass, covers the transmitting/receiving unit, and is disposed on an upper surface of the frame unit so that the transmitting/receiving unit projects into a space separated from an inside of a room. 
   
     
     
         6 . The range hood according to  claim 5 , wherein
 the space includes a space above a ceiling wall.   
     
     
         7 . The range hood according to  claim 5 , wherein
 the space includes an internal space in a cabinet.   
     
     
         8 . The range hood according to  claim 5 , wherein
 the transmitting/receiving unit case is fixed to the upper surface of the frame unit via a fixing portion disposed under the upper surface of the frame unit.   
     
     
         9 . The range hood according to  claim 8 , wherein
 the transmitting/receiving unit case and the fixing portion are made of resin, and the transmitting/receiving unit case and the fixing portion are formed integrally with each other.
