Specifically, the suction case 62 has a rectangular inlet 62a formed in a rectangular shape in a horizontal direction at the center of the bottom surface so that the suction passage IN and the suction port 62a communicate with each other, as shown in FIG. 3A. Similarly, first and second discharge ports 62b and 62b 'having a slit shape are separately formed at the front and rear ends of the suction port 62a, and the discharge passage OUT is branched, respectively, and the first and second discharge ports 62b and 62b' are respectively formed. In addition, as illustrated in FIG. 3B, a discharge ring 62r having a polygonal ring shape may be separately formed around the suction port 62a such that the discharge passage OUT may communicate with the discharge port 62r.

At this time, the discharge ports 62b, 62b 'and 62r are formed around the suction port 62a so that the discharge heads 62b, 62b' and 62r are discharged from the discharge ports 62b, 62b 'and 62r even when the suction head 50 is moved forward and backward. It is possible to float the fine dust hidden on the floor by the discharge air, the discharge port (62b, 62b ', 62r) reduces the flow resistance and at the same time discharge air discharged from the discharge port (62b, 62b', 62r) It is formed to be gently inclined toward the suction port (62a) to float the fine dust hidden in the bottom surface.

Next, the injection nozzle 70 may be integrally formed to have a predetermined inclination angle between the bottom surface and the suction port 62a so that its shape extends to the discharge passage OUT, but the discharge ports 62b and 62b ', 62r may be formed to have various inclination angles, respectively, so that each injection nozzle 70 having a variety of inclination angles can be selectively removable at the end of the discharge passage (OUT) To be installed.

At this time, the injection nozzle 70 is discharged inclined so that the discharge air discharged from the discharge port (62b, 62b ', 62r) toward the bottom surface in contact with the suction port (62a), the inlet ( 62a) is formed to be gathered to the formed central portion, and at the same time, the size is reduced so that the wind speed of the discharged air can be increased.

Therefore, referring to the operation of the dry upright cleaner configured as described above, if the suction head 50 is in contact with the bottom surface, and then the suction motor 56 and the brush 64 is driven by the control unit, the suction motor As the 56 is operated, suction force is generated by the vacuum pressure acting on the suction head 50 and the rotational force of the brush 64, and the suction air is introduced through the suction port 62a by the pressure difference. As the brush 64 is rotated, the bottom surface is pressurized to promote suction of a cleaning material such as hair or dog hair contained in the bottom surface.

Thereafter, the suction air flowing along the suction channel IN passes through the filter assembly 54 to filter various cleaning materials such as dust and the like, and then passes through the suction motor 56 to discharge the discharge channel. Flow along (OUT).

In particular, the discharged air flowing along the discharge passage (OUT) is discharged through the injection nozzle 70 installed at the end thereof, and guides the discharged air to be inclined with respect to the bottom surface in contact with the suction port (62a). As a result, fine dust or the like contained in the bottom surface in contact with the suction port 62a is suspended by the discharge air, and such fine dust is sucked back through the suction port 62a and the suction flow path IN. Recycle and filter out.

Figure 4 is a block diagram showing an example of the combined wet / dry upright cleaner according to the present invention.

The wet / dry upright cleaner according to the present invention is the same as the dry upright cleaner described above, but as shown in FIG. 4, a dust collecting container 154a and a compartment thereof are formed on the suction flow path IN formed in the main body case 152. Brush 164 is rotatable in the main body 150 is installed washing tank 154b and the suction motor 156, and the suction port (not shown) formed on the bottom surface of the suction case 162 in communication with the main body case 152 And a discharge flow path (OUT-A) for connecting the suction head 160 having a discharge port (not shown) formed thereon and connecting the suction motor 156 and the discharge port to discharge the discharged air filtered out by the cleaning material. And a washing water passage (OUT-W) connecting the washing water container (154b) and the discharge passage (OUT-A) to discharge the washing water, and installed at the end of the discharge passage (OUT-A) to clean the discharge air. A predetermined angle of inclination between the face and the suction port It is injected to the injection nozzle 170, a configuration including the discharge passage (OUT-A), and the wash water passage (OUT-W) flow channel switching valve 180 is installed so as to vary the flow path between that.

Here, the main body 150 including the main body case 152, the dust collecting container 154a, the suction motor 156, the suction head 160 including the suction case 162, the brush 164, Since the injection nozzle 170 also has the same configuration as the dry upright cleaner, a detailed description thereof will be omitted.

It is configured to inhale and store it.

In addition, although the washing tank 154b may be separately installed to be partitioned from the dust collecting container 154a, a cleaning tank formed so that the dust collecting container 154a is separately partitioned inside the washing water tank 154a to reduce the installation space. The dust collecting container 154a may be installed to communicate with the suction channel IN and the discharge channel OUT-A separately, and the washing tank 154b may be the washing water channel OUT-W. It is installed to communicate with each other separately.

Of course, the dust collecting container 154a is preferably configured to filter the cleaning material in a cyclone method by adjusting the installation positions of the suction passage IN and the discharge passage OUT-A.

In particular, the discharge passage OUT-A connects between the suction motor 156 and the discharge port (not shown), and the washing water passage OUT-W is the washing water reservoir 154a and the discharge passage OUT-A. A) is connected between, and the flow path switching valve 180 is installed between the discharge flow path (OUT-A) and the washing water flow path (OUT-W) to be used in both dry and wet.

In this case, when used in a dry manner, the control unit controls the operation of the flow path switching valve 180 to close the washing water flow path OUT-W and simultaneously open the discharge flow path OUT-A. The fine dust contained in the bottom surface of the cleaning is suspended and re-suctioned by using the discharged air, which is filtered and cleaned.

On the other hand, when used in a wet manner, the control unit controls the operation of the flow path switching valve 180 to open the washing water flow path OUT-W and simultaneously open the discharge flow path OUT-A. By varying the flow of the cleaning material, the cleaning air is discharged so that the washing water is sprayed even if there is no separate pump, or the washing water flow path OUT-W is closed and the discharge flow path OUT-A is opened. And to dry the cleaning bottom surface by using the discharged air in which the cleaning material is filtered.

Of course, the discharge flow path (OUT-A) and the washing water flow path (OUT-W) may be configured in various ways, and in the case of dry cleaning, various discharge air may be utilized depending on the case of wet cleaning and drying. Make sure

Therefore, the operation of the combined wet / dry upright cleaner configured as described above is as follows.

First, when used in a dry manner, the suction head 150 is brought into contact with the bottom surface, and then the flow path switching valve 180 is adjusted by the controller to close the washing water flow path OUT-W and discharge the discharge. When the flow path OUT-A is opened and the suction motor 156 and the brush 164 are driven, the vacuum pressure and the brush acting on the suction head 150 as the suction motor 156 operates. Suction force is generated by the rotational force of the 164, the suction air is introduced through the suction port 162a by the pressure difference, and the hair or pet dog contained in the bottom surface by pressing the bottom surface while the brush 164 is rotated Promote the inhalation of cleaning materials such as hair.

Subsequently, while the suction air flowing along the suction channel IN passes through the dust collecting container 154a, various cleaning materials such as dust contained therein are filtered and then discharged through the suction motor 156. It flows along the flow path OUT-A.

In particular, the discharged air flowing along the discharge passage (OUT-A) is discharged through the injection nozzle 170 installed at the end thereof, and guides the discharged air to be inclined with respect to the bottom surface in contact with the suction port. Due to this, fine dust contained in the bottom surface in contact with the suction port 62a is suspended by the discharge air, and such fine dust is sucked back through the suction port and the suction flow path IN to be filtered. .

Next, when used in a wet manner, the suction head 150 is brought into contact with the bottom surface, and then the flow path switching valve 180 is adjusted by the control unit so that the washing water flow path OUT-W and the discharge flow path OUT-. When A) is opened and the suction motor 156 and the brush 164 are driven, the vacuum pressure acting on the suction head 150 and the brush 164 as the suction motor 156 is operated are also controlled. The suction force is generated by the rotational force, and the suction air is introduced through the suction port 162a by the pressure difference, and the brush 164 is rotated to press the bottom surface to press the bottom surface of the hair or the dog's hair. Promote the inhalation of the same cleaning material.

Subsequently, while the suction air flowing along the suction channel IN passes through the dust collecting container 154a, various cleaning materials such as dust contained therein are filtered out, and then the discharge channel passes through the suction motor 156. And the washing water flows along the discharge passage OUT-W from the washing water flow passage OUT-A by the injection pressure of the discharge air, and flows along the discharge passage OUT-W by the injection pressure of the discharge air. Is discharged through).

Of course, the injection nozzle 170 guides the discharge air and the washing water to be inclined with respect to the bottom surface in contact with the suction port, whereby the filthy water cleaned while simultaneously cleaning the bottom surface in contact with the suction port is suction air. In addition, the suction is recycled through the suction port and the suction flow path IN, and collected in the dust collecting container 154a.

As such, when the wet cleaning is completed, wet drying proceeds. In this case, as in the dry cleaning, the flow path switching valve 180 is adjusted by the controller to close the washing water flow path OUT-W. Only the discharge passage OUT-A is opened, thereby allowing the discharge air to be injected through the injection nozzle 170 along the discharge passage OUT-A, thereby drying the cleaning bottom surface.

In addition, dry cleaning in the above wet / dry combined upright cleaner operates in the same manner as the dry upright cleaner.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.

When the upright cleaner according to the present invention configured as described above is used only for dry cleaning, a filter assembly and a suction motor are installed in the main body, and an inlet and a discharge port are formed at a position close to the bottom of the suction head connected thereto. And a suction flow path is formed between the filter assembly and the filter assembly, and a discharge flow path is formed between the discharge port and the suction motor, and at the end of the discharge flow path, an injection nozzle for injecting the discharge air to be inclined at a predetermined angle is installed. There is an advantage to improve the cleaning performance by removing the suction by floating fine dust hidden on the bottom surface.

In addition, the upright cleaner according to the present invention is installed in such a way that when the wet / dry combined use, in addition to the dust collecting bucket and the wash water can supply the washing water can collect the suction air and the cleaned sewage, and the dust collecting passage and At the same time as the discharge flow path is connected, the washing water flow path connected to the discharge flow path is connected to the washing water flow path, and the flow path switching valve is installed between the discharge flow path and the washing water flow path. It is possible to reduce the production cost since there is no pump for spraying the washing water by pressure, so that the washing water is sprayed by closing the washing water flow path and opening the discharge flow path when drying after wet cleaning.
