The groove protrusion 136c is formed. By this configuration, when the button 136 is pressed, the inclined groove protrusion 136c moves the fixing ring 133 to the inside of the knob 35 while pressing the inclined groove 133c, and thus, the fixed ring protrusion 134 is moved. The bracket is separated from the groove 132. However, when the button 136 is not pressed, the spring 135 pushes the fixing ring 133 toward the cylindrical bracket 131, whereby the fixing ring protrusion 134 is inserted into the bracket groove 132 while the knob 35 is pressed. ) Cannot be rotated.

By the configuration of the roller fixing part 130, when the button 136 is pressed, the fixing ring 133 is moved to the inside of the knob 35 so that the fixing ring protrusion 134 is separated from the bracket groove 132. In this state, the knob 35 can be rotated. Then, when the knob 35 is rotated once, the fixing ring protrusion 134 is rotated along the end of the cylindrical bracket 131 and then comes back to the position of the bracket groove 132. At this time, the spring 135 elastically biases the fixing ring 133 in the cylindrical bracket 131 direction, so that the fixing ring protrusion 134 is the bracket groove 132 when the fixing ring protrusion 134 comes to the position of the bracket groove 132. ) So that the knob 35 is no longer rotated. That is, the knob 35 may be rotated exactly one by the roller fixing part 130, and thus the roller 30 is also rotated exactly one time so that the clean surface of the mop comes to the pressing part bottom 20a.

Meanwhile, as shown in FIG. 5, the roller 30 has a stopper gear 137 having a plurality of stopper grooves 137a formed on the outer circumference thereof to restrain the rotation thereof. The stopper 138 may be installed in the main body 10 to restrain the rotation of the stopper gear 137 while being inserted into or separated from the stopper groove 137a. Such a stopper can be implemented in various ways, for example, the ball 138a fitted to the stopper housing 138b, and the elasticity to elastically bias the ball 138a toward the stopper gear 137 by being embedded in the stopper housing 138b. It may be composed of the member 138c.

On the surface of the track belt 40, the friction generating part 42 which generates friction with the contact surface of the mop 70 is able to orbitally move the mop 70 surrounding the pressing part 20 and the roller 30. Formed. The friction generating part 42 may be implemented in various forms. In this embodiment, the friction generating part 42 includes a plurality of protrusions protruding sharply from the surface. However, if it can generate friction with the contact surface of the mop 70 can be of course in a variety of forms, such as velcro.

The wheel 50 is installed to be rotated at the rear of the main body 10, preferably at the rear of the main body 10 in which the water tank is embedded. By adopting the wheel 50, the main body 10 can be easily moved back and forth.

The mop 70 has a length that is an integral multiple of the bottom of the pressing unit 20, and if the length of the bottom of the pressing unit 20 is 20 cm, the length of the mop is preferably about 60 cm. Both ends of the mop 70 are attached to each other and the configuration for this can be implemented in various ways. In this embodiment, it is implemented by installing the Velcro 70a (70b) that is detachable to both ends of the mop (70). The mop 70 is composed of an adhesion surface layer that adheres to the floor and undergoes cleaning, and an absorption layer that can absorb moisture.

Alternatively, as shown in FIG. 8, the mop 170 has the same area as the base surface 170 having the velcro 170a and 170b attached to and detached from both ends, and the bottom surface 20a of the pressing part 20a on the base surface 170. The bottom contact surface 171 may have a structure formed. In this case, a partition surface 170c is formed between the bottom contact surface 171 and the other bottom contact surface 171 ′ at a predetermined interval. In this structure, when the partition surface 170a is positioned on the curved surface 22 in front of the pressing portion, the bottom contact surface 171 is brought into close contact with the pressing portion bottom 20a so that the user presses the pressing portion. It can be seen that the clean mop surface is located on the bottom 20a.

Next, the operation of the steam cleaner having the above structure will be described.

First, the mop 70 is wrapped around the pressing unit 20 and the roller 30, and then attached to the velcro 70a, 70b formed at both ends. Then, the mop 70 is wound around the pressing unit 20 and the roller 30 in an infinite track. In this state, power is applied to the steam generating unit 60 to generate steam and proceed with steam cleaning.

During the steam cleaning of the floor B, if the mop 70 in close contact with the pressing unit 20 becomes dirty, the user rotates the knob 35. Then, the orbiting belt 40 wound around the roller 30 and the pressing unit 20 is rotated while orbiting, and thus the mop 70 is also orbitally moved by the orbiting belt 40. Through this process, the dirty part of the mop 50 that is in close contact with the bottom of the pressing unit 20 is replaced with a clean part.

When the mop 70 is removed after the steam cleaning is finished, the roller 30 is rotated to bring the mop to the position where the velcros 70a and 70b are visible, and then the velcros 70a and 70b are removed. To separate the mop 50 from the main body 10. The separated mop 70 is washed and reused.
