As shown in these figures, the inlet valve 152, the inner valve 220 is inserted into the water inlet 150 and fastened, the outer side provided on the upper side of the inner valve 220 to form an appearance Valve 240 or the like.

Inside the inner valve 220 is formed a member receiving groove 222 which is a space having a predetermined size. The member accommodating groove 222 accommodates the flow member 252 to be described below to flow up and down. In addition, the member guide 224 is formed up and down in the central portion of the member accommodating groove 222. The member guide 224 is formed in a cylindrical shape having a diameter smaller than the inner diameter of the member receiving groove 222, to guide the vertical movement of the flow member 252 to be described below. Inside the member guide 224, a fastening guide 244 to be described below is inserted and accommodated.

A valve barrier 226 is formed at the central portion of the inner valve 220. The valve barrier 226 divides the space inside the inner valve 220 up and down, and the member receiving groove 222 described above is formed on the upper side, and the steam flow hole 228 is formed on the lower side.

The valve barrier 226 is formed with a steam passage hole 230 penetrates up and down. The steam passage hole 230 guides the steam generated by the steam generator 120 to move upward of the valve barrier 226 via the steam flow hole 228. The steam passage hole 230 is selectively shielded by the flow member 252 to be described below, and consists of one or a plurality of holes.

On the outer circumferential surface of the inner valve 220, a screw thread 232 is formed in a spiral direction to be screwed to the water inlet 150. A discharge groove 236 is formed in the edge portion 234 formed at the upper end of the inner valve 220. That is, four discharge grooves 236 are formed on the front, rear, left, and right sides of the edge portion 234, and the discharge grooves 236 move upwardly through the valve barrier 226 through the steam passage hole 230. It is the part that guides the discharge of steam.

A plurality of fixing protrusions 238 are further formed at the edge portion 234. The fixing protrusion 238 is inserted into the protrusion accommodating part 242 of the outer valve 240 to be described below to facilitate the coupling of the inner valve 220 and the outer valve 240.

The fastening guide 244 is protruded downward from the center of the bottom surface of the outer valve 240. The fastening guide 244 is inserted into the member guide 224 of the inner valve 220, and a fastening bolt groove 244 'to which the fastening bolt 246 is fastened is formed.

The inlet valve 152 is further provided with a pressure regulating means 250 for adjusting the steam pressure generated by the steam generating device 120. That is, when the pressure of steam generated by the steam generator 120 is increased between the inner valve 220 and the outer valve 240, a part of the steam (water vapor) is discharged to the outside. Pressure control means 250 to be provided is provided.

The pressure regulating means 250 is a flow member 252 is installed to flow in accordance with the steam pressure in the steam generator 120, and an elastic member 254, etc. to block the movement of the flow member 252 It is composed.

As illustrated, the flow member 252 has an annular annular shape and is made of a heat resistant material. The flow member 252 is accommodated in the member receiving groove 222. Accordingly, as shown in FIG. 9, the bottom surface of the flow member 252 is in contact with the top surface of the valve barrier 226 to shield the steam passage hole 230 formed in the valve barrier 226.

A support groove 252 ′ is recessed downward in an upper surface of the flow member 252. The support groove 252 ′ is formed in a ring shape corresponding to the lower end of the elastic member 254, and is a portion in which the lower end of the elastic member 254 is accommodated.

The elastic member 254 is provided on the upper side of the flow member 252, to block the upward movement of the flow member 252, preferably made of a compression spring. Therefore, the lower end of the elastic member 254 made of such a compression spring is inserted into the support groove 252 'and fixed.

On the other hand, the steam generator 120 is further provided with a moving valve 260 that can check the water level (check), the configuration and installation state of such a moving valve 260 is shown in Figures 11 to 13 have. That is, in FIG. 11, a part of the steam generator 120 in which the moving valve 260 is mounted is shown in cross-sectional view, and in FIG. 12, a part of the steam generator 120 in which the inlet valve 152 is separated. Is shown in cross section. 13 illustrates a cross section of the transfer valve 260.

As shown in these figures, the steam generating device 120 is provided with a moving valve 260 is changed in the vertical position according to the water level stored in the inside, such a moving valve 260 is the steam generator ( It is configured to float on the water stored in the water storage unit 138 of 120. That is, it is preferable that the air receiving groove 262 'to be described below is formed to float on the water.

In addition, the moving valve 260 is preferably made of a material that can float on the water itself. That is, it is preferably made of a material having a specific gravity of 1 or less, so that it can float on water by itself.

The moving valve 260, the valve body 262 in contact with the water stored in the steam generator 120 and a pair of head support extending upward from the upper surface of the valve body 262 ( 264 and a valve head 266 formed on an upper end of the head support 264.

The valve body 262 has a cylindrical shape shielded upward. That is, the bottom surface of the valve body 262 is formed with an air receiving groove 262 'recessed upwardly. Predetermined air enters the air receiving groove 262 '. Therefore, when the moving valve 260 is placed on the water, the air contained in the air receiving groove 262 'is trapped without being able to escape to the outside. As a result, the air inside the air receiving groove 262 'serves to allow the transfer valve 260 to float on the water.

The head support portion 264 is formed in pairs, respectively installed at a predetermined distance apart from each other, and have a flat plate shape. In addition, the pair of valve heads 266 are installed on the pair of head support units 264, respectively.

Since the pair of head support 264 has a predetermined length, it has a predetermined elasticity by itself. Therefore, when the pair of valve heads 266 formed on the upper ends of the pair of head support parts 264 touch each other, the head support parts 264 are bent by elasticity and the pair of valve heads 266 They touch each other.

The valve head 266 is formed to have a larger width than the head support 264. That is, the pair of valve heads 266 flat cross-sectional size is formed to be relatively larger than the pair of head supports 264 flat cross-sectional size. This is to prevent the moving valve 260 from being removed from the guide hole 272 of the flow guide 270 to be described below.

The upper surface of the pair of valve heads 266 is streamlined. That is, the upper surface of the pair of valve heads 266 is formed to have a predetermined curvature, as shown. This is for the valve head 266 to be easily inserted into the guide hole 272 of the flow guide 270 to be described below.

In addition, a flow guide 270 is further formed at the water inlet 150 through which water is introduced into the steam generator 120 to guide the vertical flow of the moving valve 260. That is, as shown in FIGS. 11 and 12, the flow guide 270 is integrally formed with the water inlet 150 at a lower portion of the water inlet 150.

In addition, the flow guide 270 is formed with a guide hole 272 for guiding the head support 264 of the moving valve 260 to be inserted and flows up and down. The inner diameter of the guide hole 272 is formed to have a size larger than that of the outer circumferential surface of the pair of valve heads 266. That is, when the pair of valve heads 266 abut each other, the size of the outer circumferential surface of the pair of valve heads 266 should be smaller than the inner diameter of the guide hole 272. This is to prevent the pair of valve heads 266 from being easily separated after being inserted through the guide hole 272.

On the other hand, the pair of valve heads 266 is not in contact with each other, the size formed by the outer peripheral surface of the pair of valve heads 266 in the upright state as shown in Figure 13 should be larger than the inner diameter of the guide hole 272 do. In this case, the cross-sectional size of the pair of head support 264 should be smaller than the inner diameter of the guide hole 272. That is, the inner diameter of the guide hole 272 should be larger than the width of the head support 264.

In this case, as shown in FIG. 11 and FIG. 12, the valve head 266 does not pass through the guide hole 272 while the moving valve 260 is inserted into the guide hole 272 and is separated. This is avoided.

Hereinafter, the operation of the nozzle having the above configuration and the steam combined vacuum cleaner employing the nozzle will be described.

First, the user opens the water inlet 150 by rotating the inlet valve 152, and then supplies water from the outside through the water inlet 150. And when the appropriate amount of water is accommodated in the water storage unit 138, the water inlet 150 is shielded again by using the inlet valve 152.

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. 5, foreign matter is sucked 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).

The 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. 6. 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.

Next, the mounting of the moving valve 260 and the user looks at the process of injecting the external water through the water inlet 150 to the water storage unit 138 of the steam generator 120.

First, in order to fasten the moving valve 260, the pair of valve heads 266 are pushed upward from the lower portion of the guide hole 272 of the flow guide 270 in a state in which the pair of valve heads 266 abuts each other. In this case, the pair of valve heads 266 penetrates through the guide hole 272 and is exposed to the upper side of the flow guide 270 to be in a state as shown in FIG. 12.

In addition, the user inputs water into the water storage unit 138 during the first time and in use. In this case, first, the inlet valve 152 is peeled off, and then the steam generator (through the water inlet 150) 120) Water is injected into the outside.

When water is introduced into the water storage unit 138, the moving valve 260 floats on the water, and as the water level increases, the height of the moving valve 260 is gradually increased. That is, the moving valve 260 is made of a material that can be lifted by itself, and at the same time, an air receiving groove 262 'is formed in the valve body 262 to trap the air, so that the action of the air Due to the influence of the material and the moving valve 260 is easily floated on the water.

When the moving valve 260 floats on the water, it is guided by the flow guide 270. That is, as shown in FIG. 12, since the head support 264 is inserted into the guide hole 272, the head support 264 is moved according to the floating of the moving valve 260. The guide hole 272 is raised while sliding inside.

As the water input through the water inlet 150 continues, the transfer valve 260 gradually rises with the water level, and finally, the upper surface of the valve body 262 is the flow guide 270 as shown in FIG. 14. Touch the bottom. In this case, the valve head 266 of the moving valve 260 is almost positioned at the upper end of the water inlet 150. Therefore, at this time, the user can easily recognize the valve head 266 from the outside as shown in Figure 14, it is possible to measure the water level.

As a result, when the user inputs water through the water inlet 150, the user may input water while looking at the position of the valve head 266, and may estimate a time at which water input is stopped. That is, when the valve head 266 rises to the position as shown in FIG. 14, the water input is stopped, the inlet valve 152 is fastened, and the cleaning operation is performed again.

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

For example, in the above embodiment, the case in which the object to be injected into the water storage unit 138 to be evaporated and sprayed to the outside is water, but is described as an example. Of course, aqueous solutions or liquids of other properties may be used. That is, it is also possible to add other substances besides pure water to aid the cleaning.

In addition, the above embodiment illustrates a case in which the moving valve 260 is configured to change the vertical position according to the water level stored in the steam generating device 120, but such a moving valve 260 to the left and right It may also be possible to configure it to flow.

In the nozzle of the cleaner according to the present invention as described above, the foreign material attached to the bottom surface is wiped off with a mop while at the same time sucking the foreign material. That is, a suction port through which foreign matter is sucked is formed at the front end of the nozzle, and at the same time as the mop is mounted, steam is injected into the mop.

Therefore, when the user performs cleaning while pushing the nozzle forward, foreign matter is first sucked in and removed through the suction port, and the foreign matter attached to the bottom surface is removed by a mop containing steam secondaryly. Vacuum cleaning and mop cleaning is effected at the same time.

In addition, in the present invention, a moving valve capable of measuring the water level inside the steam generator is provided inside the nozzle. Therefore, the user can easily recognize the time when the water input is completed by detecting the height of the transfer valve while injecting water through the water inlet to stop the water input. Therefore, there is an advantage that the problem of overflowing water due to excessive water input as in the prior art.
