  • the fastening member of the cleaning hole cover coupling portion 1854 is removed and the cleaning hole cover 185 is separated from the housing, the fourth flow path 182b is exposed to remove the dust thereof.
  • the flow path unit includes an outer cover 187.
  • the outer cover 187 is a component that shields the cleaning hole cover 185 and prevents air leakage.
  • the outer cover 187 is disposed outside the cleaning hole cover 185 and is detachably coupled to the housing 110 to selectively shield the cleaning hole cover 185.
  • the outer cover 187 is disposed in the outer cover installation hole 1862.
  • the outer cover 187 is coupled to the housing by the fastening member. When the outer cover 187 is separated from the housing, the cleaning hole cover 185 is exposed.
  • a cleaning hole cover installation unit 186 is a component having a space in which the cleaning hole cover 185 is installed.
  • the cleaning hole cover installation unit 186 includes a cleaning hole cover installation hole 1861, an outer cover installation hole 1862, and a step 1863.
  • the cleaning hole cover installation hole 1861 is formed in the housing 110, and the cleaning hole cover 185 is inserted into the cleaning hole cover installation hole 1861.
  • the cleaning hole cover installation hole 1861 is formed in the rear surface of the housing 110.
  • the outer cover installation hole 1862 is formed in the housing 110 and disposed so that at least a part overlaps the cleaning hole cover installation hole 1861, and the outer cover 187 is inserted into the outer cover installation hole 1862.
  • the outer cover installation hole 1862 is formed in the rear surface of the housing 110.
  • the outer cover installation hole 1862 is disposed in a rear surface of the cleaning hole cover installation hole 1861 and communicates with the cleaning hole cover installation hole 1861.
  • the step 1863 is formed between an outer perimetric surface of the cleaning hole cover installation hole 1861 and an outer perimetric surface of the outer cover installation hole 1862.
  • the outer cover 187 is caught on the step 1863.
  • the cleaning hole cover installation hole 1861 and the outer cover installation hole 1862 are disposed in the housing.
  • An area of the outer cover installation hole 1862 is smaller than an area of the cleaning hole cover installation hole 1861. Accordingly, the step 1863 is formed on the outer perimetric surface of the outer cover installation hole 1862. The outer cover 187 is caught on the step 1863 so that the outer cover 187 can be easily and firmly coupled to the housing.
