Next, when power is applied from the outside, such power is supplied to the main body 50 and the nozzle 100. Therefore, a motor assembly (not shown) provided inside the main body 50 rotates to generate a suction force.

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. The foreign matter in the air introduced into the main body 50 is collected by the filter assembly (not shown) provided in the dust collecting unit 52, the foreign matter filtered air is the motor assembly (not shown) It is discharged to outside.

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 bottom of the heater 140 is installed on the upper surface of 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, when the user does not perform the cleaning operation combined steam cleaner as described above is the generation of steam generated by the steam generator 120 is stopped. That is, in the state in which the user grips the operation handle 80, the contact portion 242c of the flow member 242 presses the safety button 244a of the safety switch 244 upwards. The power supplied to 120 is normally supplied.

On the other hand, when the user temporarily stops the cleaning operation and releases the grip of the operation handle 80, the flow member 242 moves downward by its own load or a return member (not shown) provided separately. The contact portion 242c is spaced apart from the safety button 244a of the safety switch 244.

In this case, the power supplied to the steam generator 120 is cut off. Of course, even if the control panel (not shown) by the user's setting, even if the contact portion 242c of the flow member 242 and the safety button 244a of the safety switch 244 are spaced apart from each other (About 5 seconds to 15 seconds) may be set so that power is continuously supplied to the steam generator 120.

In addition, when the steam combined vacuum cleaner is operated for the first time under the control of the control panel, the safety means 240 for a set time or until the water temperature of the steam generator 120 becomes a set temperature. ) Will not cut off the power supply.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the combined vacuum cleaner according to the present invention as described above, the foreign material attached to the bottom surface by wiping the foreign material at the same time by injecting steam through the nozzle to wipe off with a rag. Therefore, there is an effect that vacuum cleaning and mop cleaning are simultaneously performed by one operation.

In addition, in the steam combined vacuum cleaner according to the present invention, there is provided a safety means for selectively shutting off the power supplied to the steam generator according to whether the user grips the operation handle. Therefore, when the user temporarily stops the cleaning operation, since the generation of steam is blocked, there is an advantage that the damage caused by the high temperature steam is prevented. That is, even when the user stops the cleaning operation as in the prior art, steam is continuously generated and the floor is damaged by the heat of the steam, or the risk of a safety accident in which the user is burned by high temperature steam is prevented. .
