Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

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 the filter unit 50 for filtering the 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 body 22 made of aluminum die casting, and the heater is installed in the body 22 to heat the water ( 24 and a heater passage 28 for heating the water inside by using the heat from the heater 24 in the body 22.

The heater 24 is a portion that generates heat by the application of power, it is preferably installed in the body 22 so that the generated heat can be conducted to the interior of the heater passage (28). The heater passage 28 is preferably formed of copper pipes for preventing scale generation due to thermal conductivity and water flow.

A nozzle portion 26 having a reduced diameter is formed at the right end of the heater passage 28 so that the water heated in the heater passage 28 can be steamed and sprayed.

In the present invention, the water for forming steam is embedded in the bucket 60, the bucket 60 is installed detachably from the outside of the casing (10). And the water in the bucket 60 is supplied to the auxiliary heating device 62 is installed in the casing (10). On this supply passage, for example, a valve body 63 installed in a humidifier or the like to supply a certain amount of water may be provided.

The auxiliary heating device 62 is a device for preheating the water supplied from the bucket 60, because it is difficult to temporarily heat the cold water in the steam generator 20. Therefore, the auxiliary heating device 62. The heater is installed inside to preheat the water at room temperature to about 40 to 50 ℃. The preheated water is supplied to the heater passage 28 described above along the inner passage 66 by the pump 64.

The inner passage 66 is connected to the inner supply passage 29b immediately before the steam generator 20, and an end portion of the inner supply passage 29b communicates with the inside of the dust collecting chamber 40. It is.

An external supply passage 29a is connected to the nozzle unit 26 of the steam generator 20, and the external supply passage 29a is configured to communicate with the outside of the casing 10. An injection hose (not shown) may be installed outside the supply passage 29a to inject steam to a predetermined place. 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.

The internal supply passage 29b is provided with a dust collecting cylinder 40 provided on the inner lower end of the casing 10, and a check valve 27 is provided in the middle of the internal supply passage 29b. When the check valve 27 is heated inside the steam generator 20 and reaches a constant pressure, the steam collecting cylinder 40 inside the check valve 27 is not discharged to the outside by the external supply passage 29a. ) To discharge high pressure steam. For example, when the nozzle unit 26 is blocked in a state where steam is generated inside the heater passage 28, the steam inside the heater passage 28 is gradually increased in pressure. When the pressure is increased to the inside of the heater passage 28, the high pressure steam can be discharged to the dust collecting chamber 40 along the inner passage 66 and the inner supply passage 29b.

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 dust collecting container 40 is detachably installed in the casing 10 of the vacuum cleaner, and is a container capable of collecting relatively large foreign matter 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. In this way, the foreign matter falling into the dust collecting container 40 is substantially foreign matter that is relatively large in weight with water sucked back after being sprayed to the outside through the external supply passage 29a in the steam generator 20 described above.

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, a 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 collect in the dust collecting container 40. .

In addition, the filter unit 50 inside the casing 10 is substantially formed in a predetermined space for collecting dust, and one side thereof 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.

As described above, the vacuum cleaner according to the present invention has a steam injection function for injecting steam formed through the steam generator 20 to the outside through an external supply passage 29a. Therefore, where necessary, it is possible to perform the desired cleaning by spraying steam through the external supply passage (29a).

In addition, when performing a function as a vacuum cleaner, the suction force generated by the driving of the driving motor (M) is to suck the outside air containing dust through the inlet hole (42). 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 contaminants) formed by steam injected in the steam mode 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. The air supplied to the filter unit 50 enters 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.

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.

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.

According to the present invention as described above, it can be seen that the steam mode or the suction mode can be selectively selected. Therefore, the part that needs to be cleaned by steam can partially remove the old pollutants by intensively spraying steam and completely suck water and general foreign substances produced by the sprayed steam using the normal suction mode. You can expect the benefits of being able to.

In addition, the internal passage is configured such that steam generated in the vacuum cleaner is not sprayed to the outside, and there is no fear of burn due to the high temperature steam, thereby providing an advantage of providing a substantially safe driving state.
