Description

Vacuum cleaner having steam spray device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a steam spray device and configured to allow various types of cleaning by inhaling a portion which cannot be cleaned by general air suction only after steam spraying.

The vacuum cleaner is a device that sucks air containing foreign substances and performs cleaning through a filtering device installed therein. In a general vacuum cleaner, cleaning is performed by simply inhaling foreign substances and filtering them by using a suction nozzle running in contact with a floor or the like.

However, in such a vacuum cleaner, only the foreign matter in inhalable state can be cleaned. That is, the dust or trash can be separated from the floor and the like to clean only the foreign matter that can be sucked into the vacuum cleaner body by a constant suction force. For example, foreign matter or contamination on the floor or the like has a disadvantage in that it cannot be cleaned using a general vacuum cleaner as described above.

In order to make up for the above disadvantages, a vacuum cleaner having a steam jet has been proposed. For example, according to the technique proposed in Korean Patent Publication No. 95-28729, a steam spraying device is installed on the bottom of a suction nozzle of a cleaner, and a cleaner which can be wiped with a mop provided on the bottom of the suction nozzle, such as steam injection, is disclosed. It is. However, according to such a vacuum cleaner, since steam cannot be sprayed intensively to a pollutant substantially, a limit is shown to steam cleaning. In addition, since the steam injection device is configured to be installed near the suction nozzle, a large number of structural and functional groups are followed in practical application.

In addition, the vacuum cleaner disclosed in Korean Patent Registration No. 10-0110815 also has a steam injection device including a heater in the suction nozzle portion, and as described above, a certain limit is indicated in actual design and application, and at the same time, Inconvenience has been raised, which makes it impossible to concentrate injection.

In addition, the technology disclosed in the Republic of Korea Patent Registration No. 10-0303875 is also configured to perform the operation of wiping the floor by the injection of steam and mop at the same time, these techniques also have the same problem as described above.

And the above-mentioned prior art is configured to wipe the water generated on the bottom surface by spraying the steam, it does not have a suitable dust collecting container that can actually treat the water sucked after the steam injection. That is, according to the conventional technology, since there is no device for separately collecting the water sucked when inhaling the air again after steam injection, there is an inconvenience in use that it is difficult to clean more efficiently when using steam. will be.

The present invention is to solve the conventional problems as described above, to provide a dust collector mounting device of a vacuum cleaner configured to enable the intensive injection of steam, and to efficiently remove the water by the injected steam. It is a basic purpose.

And to filter the fine foreign matter contained in the air introduced into the casing through the inner inlet, it further comprises a filter including a filter.

In addition, the dust collector has shown an embodiment in which the screw portion formed on the upper outer circumference thereof and the screw portion formed on one side of the casing are detachably coupled to each other so as to be screwed to the screw portion.

According to another embodiment, the filtering net is provided at the end of the inner inlet communicating with the dust collecting container.

And a vacuum cleaner according to another embodiment includes a water tank containing water; A heater installed inside the bucket to vaporize water; The apparatus further includes an external supply passage formed to supply steam vaporized by the heater to the outside.

The vacuum cleaner according to the present invention as described above, for example, after the heavy foreign matter, such as water made by the injected steam efficiently removed from the dust collector, the secondary filtering can be performed inside the casing.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings. In the following description of the present invention, as with the overall configuration of a vacuum cleaner having a steam spraying device to which the present invention is applied, a dust collecting device will be described.

1 shows a configuration inside the main body of the vacuum cleaner according to the present invention. The vacuum cleaner main body according to the present invention as shown, the outer shape is formed by the casing 10, the handle 12 for the user to grip the upper side of the casing 10, the user vacuum cleaner A plurality of attachment hook portions 14a and 14b to which a shoulder hook for carrying on a shoulder can be attached are formed.

The casing 10 has a steam generator 20 for generating steam for cleaning, a suction force generator 30 for sucking air containing foreign substances from outside, and water from steam among the foreign substances being sucked. And a dust collecting container 40 for collecting a relatively heavy foreign matter, and a filter unit 50 for filtering fine dust after the foreign matter is primarily filtered in the dust collecting container.

First, the steam generator 20 will be described. Steam generating unit 20 according to the present invention is installed in the casing 10, the water tank 22 for embedding the water for forming steam, and is installed in the water tank for heating the water The heater 26 is comprised. The bucket 22 is capable of storing a predetermined amount of water therein through the inlet 24 opened and closed by the cap 23. In addition, the heater 26 installed in the bucket 22 means a heating device capable of heating and steaming the water in the bucket 22 by applying power. Naturally, the heater 26 can be applied to any type of heater as long as it can boil water and steam it. The heater 26 may be formed of stainless steel in consideration of contact with water.

The steam generated by being heated in the bucket 22 is supplied along the passage 28 inside the casing 10. The passage 28 is further divided into two parts, an external supply passage 29a and an internal passage 29b. An end portion of the external supply passage 29a is configured to communicate with the outside of the casing 10, and an injection hose (not shown) is provided outside the external supply passage 29a to inject steam to a predetermined place. Will be installed. The spray hose is most preferably formed of a flexible material for the user's convenience, so that the user can intensively spray steam to the desired portion.

An open / close valve 27a is provided in the middle of the external supply passage 29a. The on-off valve 27a is operated by an electrical signal, and substantially the on-off valve 27a is supplied with power by the on operation of a switch (not shown) provided outside the casing 10. When it is opened and closed.

And the inner passage 29b is connected to the dust collector 40 provided in the inner lower end part of the casing 10, and the check valve 27b is provided in the middle of the said inner passage 29b. When the check valve 27b is heated inside the water tank 22 and reaches a constant pressure, the steam is not discharged to the outside by the external supply passage 29a. It is for discharging high pressure steam.

On the outer side of the casing 10 of the present invention, the inlet hole 42 through which the outside air containing foreign matter flows is formed by the suction force generated by the suction force generating unit 30. In the inlet hole 42, for example, an extension tube or a suction hose is connected to the inlet hole 42 so that air containing foreign matter is introduced therein.

In addition, the air containing the substance introduced in this way is introduced into the dust collecting container 40 through the internal outlet 44 communicating with the inlet hole 42. The inner outlet 44 is configured to discharge the introduced foreign matter-containing air into the dust collecting chamber 40, in the illustrated embodiment, the exit hole of the inner outlet 44 is a-shaped to face downward It is bent downward.

Here, the dust collector 40 is detachably installed in the casing 10 of the vacuum cleaner, and is a container which can collect a relatively large foreign substance or water. The dust collecting container 40 is detachably mounted to the casing 10. For example, as shown in the drawing, a thread 40a is formed at the upper outer periphery of the dust collecting container 40, and the dust collecting container is mounted. A screw thread 10a is also formed at the lower end of the casing 10, and both of them can be detachably configured by screwing. In addition, of course, many other modifications are possible with respect to the configuration in which the dust collecting container 40 is detachably configured to one side of the casing 10.

The air containing the foreign matter entering the inlet hole 42 falls into the dust collecting container 40 through the inner outlet 44. Thus, the foreign matter falling into the dust collecting container 40 is, for example, a foreign material relatively large in weight with water that is injected again after being injected outside through the external supply passage 29a in the steam generating unit 20. The process of performing the actual cleaning will be described later.

The air introduced into the dust collecting container 40 is supplied to the filter unit 50 inside the casing 10 through an inner inlet 46 formed to flow into the casing 10 again. In addition, the filtering net 47 is installed at the open end of the inner inlet 46 to prevent a relatively large foreign matter from entering the inner inlet 46 and to be collected in the dust collecting container 40. .

Therefore, when the dust collecting container 40 is installed at one end of the casing 10, it should be installed to prevent the inflow of outside air, and in this aspect, it is preferable to be mounted by screwing as described above. Can be.

The dust collecting container 40 according to the present invention is installed at one side of the casing 10, and as described above, the internal outlet 44 through which the air entering through the inlet hole 42 is discharged, and the dust collecting container 40. The air discharged to) is mounted to communicate with a portion in which the inner inlet 46, which can be introduced into the casing 10 again, is formed. In the illustrated embodiment, the upper part of the dust collecting container 40 is opened, and the inner outlet 44 and the inner inlet 46 are configured to be installed in the casing 10 corresponding to the opened upper part. .

In addition, the filter unit 50 inside the casing 10 is formed as a predetermined space for collecting dust substantially, and one side is provided with a filter 52 for filtering foreign matter. Therefore, the air entering the filter unit 50 through the inner inlet 46 is filtered by the filter 52 so that fine foreign matter is collected in the filter unit 50.

In addition, the suction force generation unit 30 formed adjacent to the filter 52 has a built-in drive motor M for generating suction force, and the air filtered while passing through the filter 52 passes through the suction force generation unit ( Enter into the interior of 30). In addition, the suction force generating unit 30 is cooled while passing through the driving motor M, and then exhausted to the outside of the casing 10. As long as the filter 52 can filter out foreign substances contained in the air, it is natural to use a filter formed of any shape and material.

Next, the operation of the cleaner according to the present invention having the configuration as described above will be described.

When using the cleaner according to the present invention as described above, the steam generated in the steam generating unit 20 can be sprayed to the contaminated portion through the external supply passage (29a). The steam injection part is present as water while the pollutant is removed by the steam. These foreign matters and water are introduced through the inlet 42 by the operation of the drive motor (M).

The air introduced in this way enters the inside of the dust collecting container 40 primarily through the internal outlet 44. These foreign matters are water (including pollutants) formed by steam injected in the steam mode of the vacuum cleaner and various foreign matters contained in the air.

Among such foreign matters, foreign matters that are relatively heavy with water, fall down from the inside of the dust collecting container 40, and the primary filtering is performed. In addition, the air supplied into the dust collecting container 40 passes through the inner inlet 46 again and enters the inside of the filter unit 50. The air supplied to the inside of the filter unit 50 may actually include relatively small foreign matter. In this way, the air supplied to the filter unit 50 exits to the suction force generating unit 30 through the filter 52. At this time, the filter 52 can be completely filtered to the relatively fine foreign matter, the foreign matter is substantially collected in the filter unit 50, only clean air passes through the filter 52 Suction force generation unit 30 is supplied.

The air guided to the suction force generating unit 30 passes through the driving motor M, cools the driving motor M generated by the operation, and then completely exits to the outside of the casing 10.

And Figure 2 schematically shows the internal configuration of the vacuum cleaner according to another embodiment of the present invention. In this embodiment, the structure of the part where the air sucked including the foreign matter is guided to the dust collecting container is only slightly different from the above embodiment. Only this part will be described, and other parts are the same as in the above-described embodiment.

As shown in the drawing, air is introduced through the inlet hole 42 ′ by the driving motor M. According to this embodiment, the inner outlet 44 'and the inner inlet 46' are formed in a straight line. The outlet hole of the inner outlet 44 'is shaped to face downward, and the inner inlet 46'. The inlet hole of) is formed to face upward. Therefore, according to the present embodiment, among the foreign substances introduced through the inner outlet 44 ', the heavy one, that is, water or a large foreign substance, falls directly into the dust collecting container 40'. The fine foreign matter having a light load flows back into the filter part 50 'through the inner inlet 46'. The filtering structure thereafter is the same as in the above-described embodiment.

And also in this embodiment, the structure of the said dust collecting container 40 is substantially the same as the above-mentioned embodiment. That is, the dust collecting container 40 is installed on one side of the casing 10, and the dust collecting container 40 has an open upper surface communicating with the inner outlet 44 'and the inner inlet 46'. It is configured to do so.

According to the present invention as described above, the basic technical idea that the device for generating steam and the device for generating suction force, respectively independently installed and configured to selectively drive the inside of the vacuum cleaner main body I am doing it.

Within the scope of the basic technical idea of the present invention, many other modifications are possible to those skilled in the art, and the present invention should be interpreted based on the appended claims.

For example, the mounting apparatus of the dust collecting container according to the present invention has been described through an embodiment implemented in a vacuum cleaner having a steam spray function, but it is obvious that the present invention is not limited to such a cleaner. That is, of course, it can be applied to a vacuum cleaner having a steam spray function as in the illustrated embodiment, but it is also possible to apply to a general vacuum cleaner having no steam spray function.

According to the configuration of the dust collecting container 40 according to the present invention as described above, it can be seen that the foreign matter with a large load including water among the foreign substances to be sucked can be primarily filtered. Therefore, in particular, when injecting it again after steam injection in a vacuum cleaner having a steam injection function, it is possible to more reliably separate foreign substances with a large load and load, and thus it is possible to expect an advantage of sufficiently securing dust collection efficiency. .
