Description

Wet Vacuum Cleaner {WET BACUUM CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet vacuum cleaner, and more particularly, to a wet vacuum cleaner capable of preventing dust or fine dust sucked by a vacuum cleaner from being scattered while passing through water to prevent fine dust from scattering into the air.

A vacuum cleaner is a device that uses an air pump to suck in air and clean it. Today, it is a necessity that most homes have. The vacuum cleaner sucks in air at a high pressure by using an air pump at one side, while the other sucks air at a high speed and sucks dust and foreign substances around the same, and the dust and the like that enters the inside are filtered through the filter, . Vacuum cleaners are very convenient because they can be cleaned quickly and quickly, there is no inconvenience to bend or kneel when cleaning, and dusts on the floor can easily be removed due to small dust or static electricity .

However, such a convenient vacuum cleaner suffers from the problem that the fine dust in the dust that has been sucked through the filter is discharged into the air as it is. That is, the dust which is larger than a certain size in the air sucked together with the high-pressure air is caught by the filter, but the fine dust of a certain size or less passes through the filter as it is and is discharged into the air again. Since the fine dust that is small enough to pass through the filter is very light, it floats in the air for a long time and eventually enters the human body through the respirator. However, recent studies have shown that fine dust penetrates deeply into the lungs through the respiratory system, and fine dust that enters the inside of the body is not discharged well, which is more detrimental to health than larger dust. Therefore, in order to safely use a convenient vacuum cleaner, it is necessary to prevent a fine address from being scattered to the outside.

In order to solve the above problems, various kinds of wet or cleanable vacuum cleaners have been conventionally introduced. The wet vacuum cleaner according to the related art includes a Korean Utility Model Registration No. 20-0465529, a Korean Utility Model Registration No. 20-0443402, and the like. The vacuum cleaner is characterized in that the dust introduced into the vacuum cleaner is humidified so as not to scatter.

Also, Korean Patent Laid-Open No. 10-2010-0118812 and Korean Patent No. 10-0800641 disclose conventional techniques for cleaning air sucked with dust. However, the wet vacuum cleaner according to the related art has a problem that the suction air is not completely cleaned while passing water and the cleaning efficiency has a limit that a part of the air comes in contact with water, There is a limitation that it has a complicated structure.

1 to 4, the wet vacuum cleaner according to the present invention may include an air inlet 110, a cleaning cylinder 130, a second communicating tube 150, and an air pump 170.

The intake port 110 is composed of a head and a first communicating pipe 115, and is a well-known structure conventionally provided in a vacuum cleaner.

The cleaning cylinder 130 serves to clean the air containing the dust sucked through the air inlet 110 to collect the fine dust. The cleaning cylinder 130 is composed of an outer cylinder 133 and an inner cylinder 135 provided on the inner side of the outer cylinder 133. The outer cylinder 133 may be formed of a cylindrical or polygonal cylinder whose one end is open. The inner cylinder 135 is formed on the inner side of the outer cylinder 133, And the diameter of the outer tube 133 is smaller than that of the outer tube 133. A space is formed between the inner surface of the outer cylinder 133 and the outer surface of the inner cylinder 135 by a predetermined distance when the inner cylinder 135 is inserted into the outer cylinder 133. The other end of the inner tube 135 is connected to the inner end surface of the other end of the outer tube 133 and is connected to the end surface of the outer tube 133. [ So as to be hermetically sealed. At this time, it is preferable that one side of the inner cylinder 135 and the other side of the first communicating tube 115 are detachably attached for the purpose of cleaning or the like.

At least one exhaust hole 137 is provided at a position adjacent to the other end surface of the outer cylinder 133 on the other side of the inner cylinder 135. Thus, the air containing the foreign matter introduced into the inner cylinder 135 can be discharged to the outer cylinder 133 through the exhaust hole 137. At this time, the exhaust hole 137 is configured so that the opening portion faces one side in the circumferential direction of the inner cylinder 135. That is, as shown in FIG. 4, a portion of the inner cylinder 135 protrudes outward, and the outer side surface and the side surface in the vertical direction with respect to the inner cylinder 135 are sealed and the circumferential direction of the outer cylinder 133 is opened So that the air discharged through the exhaust hole 137 is directed in the circumferential direction of the outer cylinder 133. The effect of the air exhausted in the circumferential direction of the outer cylinder 133 through the exhaust port will be described later.

Meanwhile, the wet vacuum cleaner according to the present invention may further include a water wall 139 on the inner side of the outer cylinder 133. As shown in the drawing, the water-receiving wall 139 is formed in a spiral shape on the inner surface of the outer cylinder 133 and is provided only in the remaining portion except for a part in the other direction. The reason why the water wall 139 is provided only in one direction of the outer cylinder 133 and the effect therefrom will be described later. On the other hand, the spiral direction of the water supply wall 139 is provided in the same direction as the exhaust hole 137 described above, from one side to the other side of the outer cylinder 133. 4, when the opening portion 138 of the exhaust hole 137 provided at the other side of the inner cylinder 135 is formed to the left side (indicating the direction with reference to FIG. 4) (Clockwise direction as viewed from the top) while descending downward from the upper part. 2 and 3). The inner wall of the inner wall 135 is spaced apart from the outer wall of the inner wall 135 (see FIGS. 2 and 3) So that a passage through which air can move is sufficiently secured.

The second communicating tube 150 is formed of a cylindrical or polygonal cylinder, and the other end is connected to one side of the outer cylinder 133 described above. At this time, a filter 140 may be provided at a portion where the outer cylinder 133 and the second communicating tube 150 are coupled.

1 and 2, in an embodiment of the present invention, one side of the first communicating tube 115 passes through the other side of the second communicating tube 150, passes through the center of the second communicating tube 150, And is connected to the inner cylinder 135 of the cylinder 130. And the space between the first communicating tube 115 and the second communicating tube 150 is communicated with one side of the outer tube 133. The first communicating tube 115 is connected to the inner tube 135 and the second communicating tube 150 is connected to the outer tube 133 and the first communicating tube 115 The second communicating tube 150, and the outer tube 133 and the inner tube 135 are isolated from each other, various known shapes can be applied. For example, although not shown in the drawing, one end of the inner cylinder 135 is offset from one side of the outer cylinder 133, so that the first communicating tube 115 does not pass through the second communicating tube 150, Or may be a structure in which they are separated from each other at one inlet of the cylinder 130. It is needless to say that various known structures can be applied as long as air flow can be realized as described below.

An air pump 170 is provided at one side of the second communicating pipe 150 and may be further provided with a handle 190 if necessary. The air pump 170 discharges the internal air of the second communicating pipe 150 to the outside so that the air can be sucked into the air inlet 110 at a high pressure.

At least one backflow prevention unit 160 may be further provided inside the second communicating pipe 150 along the longitudinal direction. As shown in the figure, the backflow prevention unit 160 may have a funnel shape having a hollow portion that is wide on one side and narrows toward the other side. So that a narrow hollow portion can be provided so as to face the cleaning cylinder 130.

When the air pump 170 sucks air out of the second communicating pipe 150 and discharges the air to the outside, when the air communicates with the second communicating pipe 150, As the pressure in the cylinder 130 and the first communicating tube 115 decreases, the air is introduced at a high speed through the intake port 110, and dust and foreign matter are introduced together. This is a normal operation process of a vacuum cleaner. The wet type vacuum cleaner according to the present invention is configured such that the washing tub 130 can be detachably attached to the second communicating pipe 150 and a certain amount of washing water 131 is introduced into the washing tub 130 (See FIG. 2).

The polluted air introduced through the intake port 110 flows into the inner cylinder 135 through the first communicating pipe 115 and the contaminated air flowing into the inner cylinder 135 is provided at the other side And flows into the outer cylinder 133 through the exhaust hole 137 having the same diameter. Since the exhaust hole 137 is provided so as to face the outer circumferential surface of the inner cylinder 135 as described above, the circumference of the inner cylinder 135 along the space between the inner cylinder 135 and the outer cylinder 133 It rotates and passes. Accordingly, the washing water (water) stored in the washing tub 130 swirls in a space between the outer cylinder 133 and the inner cylinder 135 in accordance with the flow of the air, so that the fine dust contained in the contaminated air melts in the water, . The air flowing from the outer cylinder 133 to the inner cylinder 135 swirls along the outer circumferential surface of the outer cylinder 133 and thus the time it takes to stay inside the cylinder 130 becomes longer and the outer cylinder 133 and the inner cylinder 135 ) Is swirled together with the polluted air and rotates, so that the contact time with the water becomes longer and the chance of contact increases, thereby increasing the possibility that the fine dust contained in the contaminated air is washed in the water.

Since the water wall 139 is formed in the inner surface of the outer cylinder 133 and the water wall 139 is formed in the same direction as the direction of the exhaust hole 137, It serves to stop the climbing to the top. That is, the water in the cleaning cylinder 130 swirls in a space between the inner cylinder 135 and the outer cylinder 133 by the air flowing at a high pressure through the exhaust hole 137 in the direction of the outer cylinder 133, The water is rotated in close contact with the inner surface of the outer cylinder 133. Therefore, it collides with the water-receiving wall 139 provided on the inner surface of the outer cylinder 133 and can no longer be raised to the upper part. The contaminated air flowing from the inner cylinder 135 to the outer cylinder 133 can flow upward along the spiral water walls 139 or can easily flow upward along the space between the water wall 139 and the inner cylinder 135. This is because the inside of the water wall 139 is provided to be spaced apart from the outer surface of the inner cylinder 135 as described above. Even if the water in the washing tub 130 rotates at a high speed and a part of the washing tub 130 protrudes upward through a space between the water receiving wall 139 and the outer tubular surface of the inner tub 135, It can easily flow back to the lower part. Since the upper surface of the water receiving wall 139 is less influenced by the flow of air, the water protruding upward can be easily flowed down to the lower side. Part of the dust or contaminant remaining in the air that has not been cleaned while passing through the washing tub 130 is filtered by the filter 140 provided between the washing tub 130 and the second communicating pipe 150, Only the air flows into the second communicating pipe 150. The air flowing into the second communicating pipe 150 passes through the backflow prevention unit 160 provided in the second communicating pipe 150 and is discharged to the outside. After using the vacuum cleaner, the water that has been cleaned with the dust can separate the cleaning cylinder 130.

When the vacuum cleaner is laid down during or after the use of the wet vacuum cleaner according to the present invention, the water stored in the cleaning cylinder 130 flows back through the filter 140 and is supplied to the air pump 170 . Therefore, in order to prevent such a problem, the second communicating tube 150 is provided with at least one backflow prevention unit 160. The backflow prevention unit 160 is formed in the form of a funnel as described above. Since the narrow hollow portion is provided in the direction of the cleaning cylinder 130, the backflow prevention water can not pass easily. That is, in order to allow the water to pass through the backflow prevention unit 160, the water must be filled up to about half of the second communicating pipe 150 because the narrow hollow portion must be filled up to the position where the narrow hollow portion is located. Therefore, when one or more backflow prevention units 160 having the above-described structure are installed, even if water flows into the second communicating pipe 150, the airflow can not reach the air pump 170.

Although the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be limited to the embodiments described, but should be determined by the appended claims, as well as the appended claims.
