The connecting portion with the front plate assembly 3 is flat.

  It is the range hood R comprised in this way, Comprising: It heats and cooks using the cooking appliance arrange | positioned in this lower part, The exhaust fan 15 with which it was equipped is driven. Combustion exhaust gas is generated with combustion, and oil smoke or the like is generated by cooking. These are sucked in from the lower surface opening 5 of the range hood main body 1 and pass through the oil and dust collecting filter 6 to capture the oil and the like. The remaining combustion exhaust gas is discharged to the outside through the exhaust port and the exhaust duct 17.

  Part of the oil and fat generated by cooking is attached to the inner surface of the range hood main body 1 before passing through the oil and dust collection filter 6, and most of it adheres stickyly at the attached position. If left for a long period of time, part of the oil and fat and the like flows down and drips along the periphery of the lower surface opening 5 of the range hood body 1.

  Therefore, it is necessary to remove the oil and dust collection filter 6 every predetermined period and wipe away the oil and fat that has been captured. At the same time, it is necessary to wipe away the oil scum and the like stuck to the range hood main body 1 which is always exposed on the lower side from the oil and dust collecting filter 6 to keep cleanliness.

  At this time, since the spacer 60 is interposed in the connecting portion between the main body assembly 2 and the front plate assembly 3 and is flat according to the inner surfaces of the main body assembly 2 and the front plate assembly 3, in particular, oil and fat etc. are connected to the connecting portion. There is no such thing as getting in. Even if the oil and fat or the like adheres to the spacer 60, the oil and fat or the like can be wiped and removed very easily and almost completely by cleaning the inner surface of the range hood body 1.

  By forming the spacer 60 from a resin material containing a surfactant, a wettability film is formed on the surface of the flat bent portion 60b exposed from the inner surface of the range hood body 1 of the spacer 60. Therefore, it becomes easier to wipe off oil and fat adhering to the spacer 60, and since it is a resin material, even if a finger or the like touches the spacer 60, it smoothly slides to ensure safety.

  In the above-described embodiment, the spacer 60 is interposed between the flanges 40A and 40B of the front plate 12 and the front plate cover 13 constituting the front plate assembly 3. However, the present invention is not limited to this. The spacer 60 may be interposed between the flange portions 30A and 30B of the main body 10 and the main body cover 11 constituting the main body assembly 2. In short, any spacer 60 may be used as long as the recess formed in a state in which the main body assembly 2 and the front plate assembly 3 are connected to each other is formed in substantially the same flat shape as the inner surfaces of the main body assembly 2 and the front plate assembly 3.
