Description

Suction nozzle of vacuum cleaner equipped with dregs-removal device

The present invention relates to a suction nozzle of a vacuum cleaner having a foreign substance removal device, and more particularly, to suction of a vacuum cleaner configured to hygienically remove foreign substances caught in a brush sweeping while rotating a foreign substance on a carpet or a floor. Relates to a nozzle.

Generally, vacuum cleaners are classified into canister type, handy type, stick type and upright type according to the structure.

The upright vacuum cleaner includes a main body including a driving unit including a motor and a driving fan capable of generating a suction force, and a dust collecting space located above the driving unit; A suction hose for transferring the suction force generated by the main body; The suction nozzle is configured to suck air containing foreign matter such as dust on the bottom surface by the suction force transmitted through the suction hose. In addition, the suction nozzle is characterized in that the agitator, which is a rotating body including a brush for scraping off the foreign matter sandwiched between the carpet hair is configured on the bottom of the suction nozzle.

The upright vacuum cleaner configured as described above is configured such that air containing foreign substances introduced through the suction nozzle is introduced into the dust collecting space located above the driving unit through the suction hose.

Next, a configuration of a general vacuum cleaner will be described based on what is shown in the drawings. Figure 1 shows a cross-sectional view for explaining the internal structure of the upright vacuum cleaner and the flow of air.

The vacuum cleaner 10 as shown is moved while the user touches the floor surface or carpet (C) to be cleaned by the suction nozzle 2 in the process of pushing or pulling the handle (5). The air containing the foreign matter is sucked through the suction part 1 opened in the bottom of the suction nozzle 2, and the sucked air is configured to flow along the suction hose 4. The air flowing along the suction hose 4 is separated from the foreign matter in the dust collecting chamber 6 and then flows into the motor housing in which the driving motor M is built. After cooling the heat of the driving motor M while flowing inside the motor housing, it is exhausted to the outside of the vacuum cleaner through the exhaust section 7. At this time, the fine dust is finally filtered by the exhaust filter 8 configured inside the exhaust unit 7 and then exhausted.

On the other hand, the suction nozzle 2 has a built-in agitator 9 having a brush 9a formed on its outer circumference. The agitator 9 is rotated by receiving power through a belt (B) connected to the shaft of the drive motor for generating a suction force. As the agitator 9 is rotated, the foreign material caught in the wool of the carpet C is scraped and sucked. This is made possible by scraping off the foreign matter stuck to the hair of the carpet (c) while the brush (9a) is formed on the outer periphery of the agitator (9). In this process, most foreign matter is introduced into the main body through the suction port 1, but foreign matter such as hair or fluff is entangled in the brush 9a. 2, the problem of the agitator 9 will be described. FIG. 2 illustrates a main portion of a conventional suction nozzle, and is a perspective view showing only a part of an agitator mounted on the suction nozzle. As shown in the figure, the foreign material S, such as hair and fluff, is entangled in the brush 9a which is comprised spirally in the agitator 9.

The agitator 9 rotated as described above scrapes and scatters foreign substances present on the floor or carpet. That is, the agitator 9 performs an important function of sweeping the floor or carpet for effective suction of foreign matter.

However, the following problems are pointed out in the process of cleaning the foreign material by the agitator (9). That is, most foreign matter flows through the suction unit 1 to the dust collecting chamber of the main body, but foreign matters S, which are easily tangled, such as hair or lint, are entangled in the brush 9a. Due to this, it is obvious that the brush 9a is not disturbed by the entangled foreign matters and thus cannot be approached deeply into the carpet C, so that the foreign substances cannot be scraped cleanly, resulting in no clean cleaning.

As described above, in order to remove the foreign substances tangled in the brush 9a by hand, the hands are dirty and unsanitary. In addition, there is a problem that the foreign matter falls on the bottom surface in the process of removing the foreign matter is dirty again around.

An object of the present invention is to solve the problems described above, the suction nozzle of the vacuum cleaner having a foreign matter removal device to hygienically remove the foreign matter tangled in the brush of the agitator installed inside the suction nozzle To provide.

In addition, the end of the foreign material removal rod 34 is protruded toward the opposite direction in which the agitator 24 is rotated. In addition, it is also possible to form the end of the debris removal rod 34 to be pointed to effectively remove the debris.

Next, the overall operation of the suction nozzle 20 of the vacuum cleaner having the foreign matter removing device 30 according to the present invention having the above configuration will be described.

First, when cleaning is started, air is sucked in through the suction part 22 of the suction nozzle 20 assembled in the lower part of the main body of the vacuum cleaner by the operation of the driving motor (see reference M in FIG. 1). In addition, the rotational force of the drive motor is transmitted to the agitator 24 embedded in the suction nozzle 20 through a belt (see reference B in FIG. 1). As a result, the agitator 24 rotates, and the brush 24a formed on the outer circumference thereof also rotates in the process of rotating. The brush 24a rotates while protruding to the suction part 22 opened in the suction nozzle 20. Therefore, by the brush 24a of the agitator 24, the foreign matter accumulated on the floor or the carpet is wiped and scattered to help the foreign material flows through the suction part 22. In addition, the process of collecting the foreign substances introduced into the suction part 22 into the dust collecting space built in the main body through the suction hose is the same as in the prior art.

Through the cleaning process as described above, foreign matters such as hair or fluff are tangled in the brush 24a. Because of this, if the foreign matter on the floor or carpet is not properly wiped or scraped off the cleaning efficiency is reduced.

Therefore, the foreign matter removing apparatus 30 according to the present invention is attached to the bottom of the suction nozzle 20 to remove the foreign substances tangled in the brush 24a. That is, the foreign matter is separated as the brush 24a passes between the plurality of foreign matter removing rods 34 configured in the foreign material removing device 30.

Next, the operation of removing the foreign matter stuck to the brush 24a will be described. First, when the pressing portion 38a is pressed to elastically contact the insertion portion 36, the locking portion 38 and the insertion portion 36 are inserted into the insertion groove 26. At this time, when the pressing projection 38a is released, the locking portion 38 is elastically supported on the inner wall of the insertion groove 26 while being in the original position. As a result, the locking jaw 38a formed at the end of the locking portion 38 is caught by the locking groove 26a so that the foreign matter removing device 30 is mounted at the inlet 22 of the suction nozzle 20. Will be.

As described above, when the foreign matter removing device 30 is mounted, the end of the foreign matter removing rod 34 is located close to the outer circumference of the agitator 24.

In this way, when the foreign matter removing device 30 is mounted on the suction nozzle 20, and the vacuum cleaner is operated, the agitator 24, which has received the rotational force of the driving motor, rotates. In the process of rotating the agitator 24, the brush 24a passes through the foreign material removing rod 34. In this process, the foreign matter stuck to the brush 24a is removed by the foreign matter removing rod 34. In order for the brush 24a to effectively remove the foreign matter, the foreign matter removing rod 34 may be formed to face in the direction opposite to the rotation direction of the agitator 24.

Then, the removed foreign matter is sucked into the vacuum cleaner body through the suction unit 22 is collected in the dust collecting chamber. At this time, foreign matter separated from the brush 24a by the foreign matter removing rod 34 is prevented from falling to the bottom surface by the closed bottom portion 32.

When the foreign matter is completely removed from the brush 24a by the above-described operation, the operation of the vacuum cleaner may be stopped, and the foreign matter removing device 30 may be separated from the suction nozzle 20. Separating the foreign material removing device 30 may proceed in the reverse order of the fastening process. That is, the foreign matter removing device 30 may be pulled apart while pressing the pressing protrusion 38b. At this time, the locking portion 38 is elastically in contact with the insertion portion 36 by pressing the push projection 38b, the locking jaw 38a is released from the locking groove 26a.

As described above, according to the present invention, the brush 24a formed on the outer periphery of the agitator 24 rotated by the drive motor rotates to sweep and scatter foreign substances adhering to the floor or carpet wool. In the process, it can be seen that it is a basic technical idea to configure so that foreign matters such as hair or fluff tangled in the brush 24a can be removed using the foreign matter removing device 30. Within the scope of the basic technical spirit of the present invention, of course, many other modifications are possible to those skilled in the art.

According to the present invention as described above, by providing a foreign matter removal device for scraping off the foreign matter entangled by the brush of the agitator, it is possible to easily and cleanly remove the foreign matter from the brush hygienically to prevent bacteria from breeding It is expected that the effect of making it possible to provide a vacuum cleaner can be obtained.
