<P>PROBLEM TO BE SOLVED: To provide an easily removable compact exhaust device 29 consisting of less number of parts, and allowing easy cleaning. <P>SOLUTION: The compact exhaust device 29 is constructed when the exhaust device 29 evacuating the inside of a mixing unit is arranged in the side part position of the mixing unit. A filter 70 for the exhaust device 29 is housed inside a filter housing part 97 in a second duct case 69, and the second duct case 69 is installed to a first duct case 48. The first duct case 68 is mounted to a main body part 26, while an exhaust passage 73 for arranging the filter 70 and a fan 67 is formed between an intake port 71 communicated with the inside of the mixing unit and an exhaust port 72 communicated with the outside, and consequently, the number of parts is reduced. The second duct case 69 and the filter 70 can be attached/detached when the first duct case 68 is attached/detached, and cleaning can be carried out easily. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
