Description

Vacuum cleaner having steam spray device

The present invention relates to a vacuum cleaner, and more particularly, in a vacuum cleaner having a steam spraying device capable of injecting steam to a contaminated portion that cannot be cleaned by general air intake, wherein water vapor generated from the inside is sprayed to the outside. It relates to a vacuum cleaner configured to be prevented.

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, dust or garbage is separated from the floor and the like, and only foreign matters that can be sucked into the vacuum cleaner body by a predetermined suction force can be cleaned. 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.

In addition, according to the above-mentioned prior arts, a water tank containing water for making steam is provided in the suction nozzle portion, and a certain limit is pointed out in design. In the above-described conventional technique, when steam formed by heating of a heater is overheated, there is a fear that it may be directly exposed to the outside, or a portion where steam is formed may be damaged. Therefore, according to the conventional structure mentioned above, it can be said that the safety problem by steam is a concern.

The present invention is to solve the above problems, to provide a vacuum cleaner that can be used stably at the same time to prevent the concern of the user's burn by high pressure steam in the vacuum cleaner having a steam injection function. It has a basic purpose.

And the dust collecting container is preferably detachably mounted to one side of the lower side of the casing. The bucket is installed in the casing, and the heater is shown in the embodiment installed in the bucket.

According to the present invention as described above, the steam generated by the heating of the heater in the bucket provided inside the casing is discharged to the inside of the dust collecting container, it is possible to prevent the high-pressure steam is ejected to the outside of the main body 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, with reference to Fig. 1 showing an embodiment 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 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, and 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, a description will be given of the steam generating unit 20 is installed heater 26 of the present invention. 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 inside the bucket 22 means a heating device capable of heating and steaming the water inside 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 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.

The inner passage 29b is provided so as to face the dust collecting cylinder 40 provided on the inner lower end of the casing 10, and a check valve 27b is provided in the middle of the 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.

That is, when the cleaning is to be performed using the vacuum cleaner of the present invention, power is applied to the heater 26, and the water inside the bucket 22 is heated. Therefore, when the water vapor generated in the water tank 22 does not escape through the external supply passage 29a, the water vapor 22 and the passage 28 are internalized by the water vapor generated. If the water vapor is not discharged from the inside of the high pressure bucket 22 and the passage 28, not only may damage the inside of the vacuum cleaner body, but also various dangerous situations may occur.

Therefore, in the present invention, by configuring the internal supply passage (29b) to connect the interior of the dust collector (40), when a high pressure of a certain threshold pressure or more is caught inside the water tank 22, the internal water vapor in the internal supply passage Through 29b, it is possible to be discharged into the dust collecting chamber 40.

Thus, the configuration to discharge the water vapor into the interior of the dust collecting container 40 is considered in terms of safety. If the high-pressure steam is discharged to the outside of the vacuum cleaner casing 10, there is a risk of causing burns not only to the user but also to the adjacent person, and may damage other adjacent objects.

In consideration of such a point, according to the present invention, the inside of the water tank 22 in which steam is formed is communicated to the dust collector 40 by using the passage 28 and the internal supply passage 29b, thereby providing extra steam. Is able to be discharged into the dust collector 40, to solve a variety of problems due to the high temperature and high pressure steam.

The check valve 27b provided in the middle of the internal supply passage 29b is a valve that can be opened when a predetermined pressure or more is applied, and automatically opens when a pressure equal to or greater than a predetermined reference value is applied. ) Will be configured to discharge the steam inside the dust collecting container (40).

And the inlet hole 42 in which the outside air containing a foreign material flows in by the suction force generate | occur | produced in the suction force generation part 30 is formed in the outer side of the casing 10 of this invention. 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. As shown 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 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.

In the use of the cleaner according to the present invention as described above, when the power switch (not shown) installed in the outer casing is turned on, heat is generated while electricity is supplied to the heater 26. When the water inside the bucket begins to heat by the heat generated by the heater 26 and the amount of heat supplied to the water inside becomes higher than a predetermined level, steam starts to be generated.

And when the steam is generated, it can be sprayed to the contaminated portion through the external supply passage (29a) in communication with the water container (22). In other words, when operating the operation button installed on the outside of the vacuum cleaner, the on-off valve 27a is opened and the steam is discharged through the external supply passage 29a, so that the user can intensively spray the desired part. 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. And these foreign matters are water (including contaminants) formed by steam injected from 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.

When the user does not clean the steam for a predetermined time or more, the heater 26 is in a state in which power is supplied to heat the water in the bucket 22, and thus, the inside of the bucket 22 and the passage 28 are substantially reduced. ) A large amount of water vapor is formed and becomes a high pressure state. If this state lasts for a predetermined time or more, the pressure rises above the allowable value, the check valve 27b is opened, and the steam inside the water tank will be discharged into the dust collecting container 40.

According to the present invention as described above, when the steam generated by the heater 26 reaches a constant high pressure, to configure the extra steam to be discharged to the dust collector (40) inside the casing (10) I assume it is a basic technical idea.

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 gist of the present invention is, of course, applicable to a vacuum cleaner having any configuration inside the main body of a vacuum cleaner that forms steam by heating a heater provided in the casing 10.

In the above-described embodiment, the vapor formed in the bucket 22 is configured to branch into the internal supply passage 29b and the external supply passage 29a after passing through the passage 28, but is limited to such a configuration. It cannot be. For example, the external supply passage, directly installed to supply the steam formed in the bucket to the outside of the casing 10, the internal supply passage to guide the steam from the bucket to the dust collector 40, the internal supply It is also possible to form separate passages and external supply passages.

In the illustrated embodiment, the bucket 22 is illustrated and described as being installed inside the casing 10, but is not limited thereto. Of course, the bucket 22 and the heater 26 can be configured to be installed outside the casing 10.

According to the present invention as described above, it can be seen that the steam generated when the water in the water tank provided inside the main body casing of the vacuum cleaner is heated is disposed in the casing without being discharged to the outside. Therefore, the application of the configuration of the present invention is expected to provide an advantage that can provide a vacuum cleaner that can be operated substantially more safely. And by configuring the steam to be discharged to the dust collector when the internal pressure reaches a certain pressure, the effect of being able to prevent damage to the inside of the vacuum cleaner as much as possible can be expected.
