In this case, as illustrated in FIG. 7, external foreign matter is sucked together with air through the suction port 112 of the nozzle 100, and passes through the suction flow channel 160 to extend the extension pipe 60 and the connection hose. It is introduced into the main body 50 through the 70. Foreign matter in the air introduced into the main body 50 is collected by a filter assembly (not shown) provided in the dust collecting unit 52, and the foreign air is filtered out of the motor assembly (not shown). It is discharged to the outside via.

On the other hand, the steam generator 120 is operated by a power applied from the outside. That is, external power is supplied to the heater 140 to heat the heater 140. Of course, at this time, water is supplied to the water storage unit 138 from the outside through the water inlet 150, and the water absorbing filter 146 is sufficiently absorbed.

Therefore, when the heater 140 is heated, the water absorbed by the absorption filter 146 in contact with the heater 140 is heated to form water vapor. In this case, the water heated by the heater 140 is not water in the whole stored in the steam case 130, but water around the heater 140 absorbed by the absorption filter 146. .

More specifically, since the heater 140 is installed in a state surrounded by the absorption filter 146, when the heater 140 is heated, water located around the heater 140, that is, the absorption The water contained in the filter 146 is preferentially heated and converted to water vapor. Therefore, water evaporates and vaporizes within a short time (by experiment, within about 10 to 20 seconds).

Water vapor generated by the heater 140 moves downward through the steam guide 144 and flows into the steam guide member 172 as shown in FIG. 8. At this time, since the steam guide member 172 is formed long to the left and right, the water vapor in the steam guide member 172 is distributed to the left and right and discharged downward through the plurality of steam jet holes 174. .

Water vapor (水蒸氣) discharged to the outside through the steam jet hole 174 is introduced into the mop 190. Therefore, the mop 190 contains a high temperature water vapor (水蒸氣) to become a mop. When the bottom surface is cleaned in this state, foreign matter attached to the bottom surface is easily separated and removed by the mop 190.

The display unit 212 displays whether water vapor is formed. That is, when water is heated by the heater 140 to form water vapor, such a state is displayed on the display unit 212. In addition, the display unit 212 also displays whether water is insufficient. That is, although not shown, if the water shortage is detected by the measurement of the water level sensor installed in the water storage unit 138, this state is displayed to the outside through the display unit 212. Therefore, the user can take appropriate measures according to various information displayed on the display unit 212.

On the other hand, the user can selectively mount and use the mop plate 180 according to the state of the bottom surface to be cleaned.

For example, as described above, in the case where it is desired to clean the floor on which the floorboard is laid, such as an apartment, the mop 190 is first attached to the bottom of the mop plate 180, and then the mop plate 180 is attached. It is mounted on the plate receiving portion 170 formed on the bottom surface of the nozzle (100).

At this time, since the permanent magnet is built in the mop plate 180 and the plate accommodating part 170 is provided with a metal material, when the user takes the mop plate 180 near the bottom of the nozzle 100, The mop plate 180 is attracted and mounted to the plate-bearing part 170 by magnetic force.

Next, when a carpet or the like is to be cleaned, the cleaning work is performed while the mop plate 180 is removed. That is, at this time, it is not necessary to use the mop 190, rather, because the mop 190 interferes with the cleaning operation.

Therefore, at this time, the user pushes the detachment lever 186 of the mop plate 180 downward by using a toe or hand while the mop plate 180 is mounted on the bottom surface of the nozzle 100. In this case, the mop plate 180 is separated from the plate accommodating part 170 and removed. That is, since the mop plate 180 is mounted on the bottom surface of the nozzle 100 by magnetic force, when the force greater than the magnetic force is applied, the mop plate 180 may be spun by the nozzle 100. ).
