The present invention relates to a vacuum cleaner capable of spraying steam to perform sterilization lamps.

In general, wet and dry vacuum cleaners are provided to clean the floor by supplying liquid wash water to the floor, but this can be collected by suctioning dust or dirt to some extent, but when there is dust or dirt adsorbed on the floor, etc. It is impossible to clean the cleaning efficiency is lowered, as well as the inconvenience of use, such as need to clean the mop after cleaning separately.

Therefore, Korean Utility Model Registration Application No. 93-9815 filed by the present applicant proposes a vacuum cleaner for cleaning by generating steam.

As shown in FIG. 1, the vacuum cleaner is provided with a washing water storage unit 2 for storing a predetermined amount of washing water W on the upper side of the main body 1, and dust and contaminated water sucked under the vacuum cleaner. A dust collector 3 for separating and storing the back is installed, and a driving unit 5 for generating dust and contaminated water into the intake body 4 by generating a strong suction force under operation of the dust collector 3. ) Is installed.

And, the lower side of the drive unit 5 is provided with a steam generator 6 for generating steam by receiving the washing water (W) from the washing water storage unit 2, the steam generated in the steam generator (6) The steam injection nozzle (7) is blown through the steam supply pipe (6a) to the steam injection nozzle (7) coupled to the bottom of the inlet body (4), and the dust and contaminated water sucked from the inlet body (4) are discharged through the inlet hose (8). It is sent to the dust collector 3 to be stored.

However, when the steam generated in the steam generator 6 is ejected from the steam injection nozzle 7 coupled to the bottom surface of the inlet body 4 through the steam supply pipe 6a, the injection pressure must be high to the bottom surface. It becomes easy to separate the adsorbed dust or foreign matter.

Conventionally, a steam injection nozzle for ejecting steam generated by the steam generator has a branch pipe (7a) coupled to the tip of the steam supply pipe (6a) as shown in Figure 2, and the bottom of the branch pipe (7a) It is composed of a plurality of nozzles (7b) coupled to be supplied to the steam supply pipe (6a) and branch pipe (7a) by the pressure of the steam generated in the steam generator 6 to be injected through the nozzle (7b) .

However, in this conventional technique, the steam ejected into the nozzle 7b is injected by the steam pressure in the steam generator 6, so that the injection pressure is not only uniform, but also lowered. Difficult to separate foreign matters, such as cleaning efficiency is significantly reduced, there was a problem that the cleaning operation is very inconvenient because it can not supply steam in a narrow space such as the corner of the floor or the gap of furniture.

In addition, a separate pumping machine may be employed to increase the injection pressure of the steam, but there are various problems inherent in the structure, the manufacturing cost, and the size of the entire vacuum cleaner.

In the drawing, a heater (H) is mounted inside the steam generator (6), and at the other end of the steam supply pipe (6a), one end of which is connected to the steam generator (6a), a first injection unit (2) for injecting steam to the bottom surface ( 10 is coupled to the other steam supply pipe (6b) connected to one side of the steam generator 6, the second injection unit 20 is coupled to inject steam into a narrow space.

As shown in FIGS. 4 and 5, the first injection unit 10 has a plurality of through holes 11a formed at a bottom surface of the branch pipe 11 connected to one end of the steam supply pipe 6a. The inner nozzle 12 is coupled to the through hole 11a, and the plurality of intake holes are formed on the side wall to increase the injection pressure of the steam as the outside air flows into the inner nozzle 12. The outer nozzle 13 which formed 13a is combined.

On the other hand, the second injection portion 20 is coupled to the front end of the steam supply pipe (6b) connected to one side of the steam generator 6, the handle to the front end of the steam supply pipe (6b) as shown in FIG. (21) is fixedly installed, the inner nozzle 22 is coupled to one side of the handle 21, the outer nozzle formed a plurality of intake holes (23a) on the side wall on the outside of the inner nozzle (22) (23) is combined.

Next, the operation and effects on the vacuum gun according to the present invention configured as described above will be described in detail.

First, when a strong suction force is generated in the intake hose 8 according to the operation of the driving unit 5, dirt, such as dust, is sucked through the intake port 8a and the wash water stored in the wash water storage unit 2 is stored in the steam generator 6. (W) is supplied, and the steam generator 6 generates steam by heating the washing water (W) in accordance with the operation of the heater (H).

The steam generated by the steam generator 6 is injected into the first spray unit 10 through the steam supply pipe 6a.

At this time, the first injection portion 10, that is, the steam passing through the branch pipe 11 and the inner nozzle 12, as shown in Figure 5 passes through the outer nozzle 13 a plurality of intake holes (13a) The flow velocity is further accelerated by the external air introduced into the), and thus is injected to the bottom surface through the external nozzle 13 at a higher pressure.

In addition, the high temperature steam injected at this time increases the cleaning pressure by easily separating the dust adsorbed on the floor surface due to the high pressure of the injection pressure.

Accordingly, the mop member 27 is rotated by the high pressure steam injected into the first injection part 10 to clean the mop, and the contaminated water or dust adsorbed on the mop member 27 is sucked into the inlet 8a. It is sucked into the intake hose (8) through and sent to the dust collector (3), in which the dust and contaminated water are separately stored by the suction force of the driving unit (5).
