[Prior art]

 In general, water is always used to clean windows, floors, vehicles and other similar items. Water does not disinfect washed material unless a disinfectant is added. However, since disinfectants are generally strong chemical products, chemical disinfectants easily cause irritation or damage to the user's skin and pollute the environment. Therefore, a cleaning device that can be sterilized by blowing steam has been proposed. Referring to FIG. 3, the conventional cleaning device includes a housing 40, a steam generator 42, a pump 44, and a water tank 50. A discharge port (not numbered) is formed at one end of the housing 40. A base (not shown) is provided at the other end of the housing 40. A scrubbing device (not shown), such as a brush or sponge, is attached to the outlet of housing 40. The steam generator 42 is mounted in the housing 40. A nozzle 422 is attached to the steam generator 42 and faces the outlet of the housing 40. The pump 44 is mounted in the housing 40 and communicates with the steam generator 42 via a discharge pipe (not numbered).

A water tank 50 has a top and a bottom, contains water, and is attached to the base of the housing 40. A water inlet (not numbered) is formed at the top of the water tank 50, and a lid 52 having an inner bottom and an outer top is attached to the top of the water tank 50 so as to close the water inlet of the water tank 50. ing. A suction pipe 54 is attached to the bottom of the lid 52 and extends to the water tank 50. A block 56 having a passageway (not shown) is attached to the free end of the pick-up tube 54 so that the free end of the pick-up tube 54 is maintained near the bottom of the aquarium 50. A projection 522 having an axial through hole (not numbered) is formed at the top of the lid 50, and the axial through hole communicates with the pickup tube 54. The filtering device 60 is mounted between the pump 40 of the housing 40 and the water tank 50 for purifying water. The filtering device 60 has an inlet 62 located at one end of the filtering device 60 and an outlet 64 located at the other end. The inlet 62 communicates with the protrusion 522 of the lid 52 via one tube (not shown), and the outlet 64 communicates with the pump 44 via the other tube (not shown). Therefore, the water in the water tank 50 is carried by the pump 44 to the steam generator 42 through the pickup pipe 54, the lid 52, and the filter 60. The steam generator 42 heats the water, and steam is generated and blown out of the nozzle 422. When a user uses a scrub cleaning element to clean an object, the blown steam disinfects the object. In addition, since the filtration device 60 is located between the pump 44 and the water tank 50, the water is filtered before being transported to the steam generator 42. Accumulation of impurities in the steam generator 42 is avoided.

However, since the conventional filtering device 60 is attached to the housing 40 with an element positioned relatively outside the water tank 50, the housing 40 must be modified to mount the filtering device 60. Must. The configuration of the housing 40 and the mold for forming the housing are complex. The costs for manufacturing conventional steam cleaning equipment are expensive. In addition, it is difficult to attach the filtration device 60 to the housing 40 and to replace the filtration device 60 after a suitable period of use.
