Suction assembly for vacuum cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a suction port for a vacuum cleaner that sucks air containing foreign substances.

1 is an exploded perspective view showing a vacuum cleaner according to the prior art, which will be described below with reference to the conventional vacuum cleaner.

The vacuum cleaner main body 1 includes a lower cover 1a and an upper cover 1b, and one end of the suction hose 3 is connected to the suction hole 2 formed in the upper cover 1b of the main body 1. The other end of the suction hose 3 is connected to the handle (4) having a control unit.

One end of the extension tube 5 is detachably connected to the handle 4, and the other end of the extension tube 5 is connected to a connection tube 63, and the connection tube 63 sucks external air. The suction port 6 is coupled.

Various components for generating suction force and collecting foreign matters are installed in the main body 1, which will be described with reference to FIG. 2.

The main body 1 is formed with an intake hole 2 through which air containing foreign matter is introduced, and a discharge hole 11 for discharging the air from which the foreign matter is separated to the outside of the main body 1 again.

In addition, one end of the suction hose 3 inserted into the suction hole 2 is equipped with a dust collecting bag 9 for filtering dust and foreign substances sucked into the main body 1 together with air, and the discharge hole 11. ) Is provided with an exhaust filter 12 for filtering the fine dust not filtered out of the dust collecting bag (9).

In addition, a motor 7 and a fan 8 for generating suction force are installed between the dust collecting bag 9 and the discharge hole 11, and in front of the fan 8. The motor protection filter 10 is installed.

On the other hand, the inlet port 6 is provided with a variety of types to suit the intended use, the user can select the appropriate inlet port as needed. For example, when cleaning beddings such as duvets or mattresses or dusty or lint-free cleaning objects such as blankets or carpets, bedding suction inlets are used, and the bedding suction inlets are shown in FIGS. 3 and 4. The description is as follows.

The bedding inlet body 60 has an empty space therein and has an inlet body 61 forming an outer shape of the inlet body 60, and wheels 62 rotatably mounted on both sides of the inlet body 61. Is made of. Then, the connection pipe 63 is coupled to the rear surface of the suction port body 61.

On the other hand, the bottom of the suction port body 61 is formed with a main suction port 61a for sucking external air, and the bypass hole 61b for sucking external air is also formed on the upper surface of the suction port body 61.

The operation of the conventional vacuum cleaner described above will be described with reference to FIGS. 2 and 3.

When the vacuum cleaner is operated, a suction force is generated inside the main body 1 by driving the motor 7 installed in the main body 1 to rotate the fan 8, and accordingly, the main suction opening ( 61a) is sucked outside air containing dust and foreign matter, the sucked air is introduced into the dust collecting bag (9) through the suction hose (3).

Most foreign matter is filtered out of the dust collecting bag 9, and air containing fine dust, which has not been filtered out, exits the dust collecting bag 9 and moves to the rear side of the main body 1 by an exhaust filter 12. Once again filtered, it is discharged to the outside of the main body 1 through the discharge hole (11).

Referring to Figure 4 describes the operation of the suction inlet 60 as follows.

When a fan and a motor inside the vacuum cleaner operate to generate suction force inside the suction inlet 60, the air is mostly sucked through the main inlet 61a formed in the suction inlet 60, and bypasses the bypass hole 61b. Part of it also flows in.

On the other hand, since the material of the bedding is mainly made of cloth when cleaning the bedding, a part of the bedding is sucked into the main inlet 61a of the suction inlet 60 by the suction force of the vacuum cleaner and the main inlet 61a is sucked. The external air may not be introduced into the suction port 60 so that the cleaning may not be performed substantially.

However, at this time, since the outside air continues to flow through the bypass hole (61b) formed on the upper surface of the inlet body 61, bedding that is stuck to the main inlet (61a) can fall from the main inlet (61a). You will be able to continue cleaning.

On the other hand, the above-described conventional suction port 60 had the following problems.

That is, the conventional suction port 60 can easily inhale various foreign matters such as dust or hair on the surface of the bedding or carpet using only suction force.

However, due to the characteristics of the blanket or carpet, since the foreign material is deeply embedded in the inside of the blanket, the upper part is covered by a fuzz or lint.

Therefore, the user repeats the cleaning operation at the same position several times or performs the cleaning operation by excessively contacting the bottom surface of the suction port on the surface of the cleaning object, or by shaking or shaking the carpet or blanket one by one and then using a vacuum cleaner. Cleaning had to be performed, resulting in inconvenience.

The present invention has been made to solve the conventional problems as described above, the present invention is a vacuum suction device for vacuum suction that can effectively suck the foreign matter in the inside of the fuzz or fluff of the cleaning object, such as blanket or carpet during the cleaning operation For the purpose of providing

In addition, a bottom surface 110 of the inlet body 100 has a main suction port 110a communicating with the space 101, and air containing foreign matter is sucked through the main suction port 110a and connected to the connection pipe. It is configured to be suckable into the main body 1 through the 109 and the suction hose (3).

Meanwhile, a housing 102 separated from the space portion 101 by the partition wall 100a is formed inside the suction port body 100, and one side of the housing 102 is formed through the partition wall 100a. In communication with the space portion 101 and the other side is in communication with the bypass hole 130 formed on the suction port body (100).

In addition, the vibration generating means 200 is installed inside the housing 102, and is configured to generate vibration by the flow of air sucked into the housing 102 through the bypass hole 130. .

The vibration generating means 200 will be described in more detail as follows.

The vibration generating means 200, the upper and lower openings are installed in the vertical direction in the interior of the housing 102 and the hollow cylindrical surface formed with a through-hole (210a) to be able to communicate with the space portion 101 on one side The duct 210 and the floating member 220 which is installed inside the duct 210 is raised or lowered by the suction force of the air sucked into the duct 210, and the upper and lower ends of the duct 110 The upper plate 231 and the lower plate 232 connected by the connecting shaft 233 so as to selectively open and close the vibration plate installed on the lower end of the connecting shaft 233 by the vertical movement of the floating member 220 ( It consists of a vibrating member 230 to vibrate 240 up and down.

The vibration generating means 200 having such a configuration, through the bypass hole 130 into the housing 102 by the suction force according to the operation of the motor 7 and the fan 8 installed inside the main body 1. When the air is sucked in, air is introduced into the duct 210 to move the floating member 220 up and down, and the upper plate 231 of the vibrating member 230 by the vertical movement of the floating member 220. ) And the lower plate 232 up and down, the vibration plate 240 installed on the lower end of the vibrating member 230 impacts the cleaning object to generate vibration and separate dust and foreign matter from the cleaning object.

On the other hand, both side ends of the inlet body 100 is equipped with a wheel 160 to enable a smooth movement of the inlet body 100 in the front and rear direction, the inlet body 100 on the bottom 110 of the inlet body 100 The squeeze 120 is installed perpendicular to the forward and backward direction of movement.

The squeeze 120 is installed to protrude downwardly on the bottom surface 110 of the inlet body 100, when the inlet body 100 moves in the front and rear direction, for example, the fuzz and fluff of the cleaning object such as carpet or blanket (hereinafter referred to as " "Hair" is laid down by a predetermined angle in the direction in which the inlet body 100 moves to create a gap between the hair and the hair to temporarily expose its bottom to the upper side and Allows deep dust and debris to float upwards.

In this case, the squeeze 120 is formed of a material that can be elastically bent, the body portion is bent elastically in accordance with the front and rear movement of the suction inlet body 100 while laying the hair in the upright state at a predetermined angle It is desirable to apply frictional force to the hair to increase the floating performance of the dust and foreign matter inherent between the hair.

In addition, a bottom surface 110 of the inlet body 100 is generated by generating a suction force by the flow of air flowing from the housing 102 to the space portion 101 through the through hole 210a inside the inlet body 100. A suction force generating means is provided to suck the foreign matter in between the hair and the hair through the auxiliary suction port 321 formed in the.

The suction force generating means will be described in more detail below.

The suction force generating means is formed to gradually decrease its cross-sectional area toward the central portion of the flow path, one end thereof is communicated with the through-hole 210a of the duct 210 and the other end is communicated with the space portion 101 inside the bypass hole ( Venturi tube 310 for guiding the air introduced through the 130 to the space portion 101 side, and the suction flow passage 320, one end is in communication with the venturi tube 310 and the other end is in communication with the auxiliary suction port 321. It is composed of

According to this configuration, when the air flowing from the housing 102 to the space portion 101 passes through the venturi tube 310 at a predetermined flow rate, the central section of the venturi tube 310 has an inlet side 310a and As the cross-sectional area of the outlet side 310b is narrower than the cross-sectional area of the outlet side 310b, the low pressure portion is formed in the central portion of the venturi tube 310 having a narrow cross-sectional area so that the air flow rate is faster and the pressure is lower than that of the adjacent side. The suction force is generated in the suction flow passage 320 connected to one end thereof.

Accordingly, the air and the foreign matters of the adjacent portion are sucked through the auxiliary suction port 321 formed at the lower end of the suction flow pipe 320 and guided upward along the suction flow pipe 320, and the center of the venturi pipe 310 is positioned. After being sucked into the venturi tube 310 through the discharge hole 315, the venturi tube 310 is discharged to the space portion 101 through the outlet side 310b of the venturi tube 310.

In this case, as the upper end portion of the suction flow path tube 320 communicating with the venturi tube 310 has a minimum cross-sectional area, the central portion of the venturi tube 310 forms the lowest low pressure region in the venturi tube 310. By communicating, it is desirable to obtain a suction pressure as strong as possible.

On the other hand, the auxiliary suction port 321 formed in the bottom surface 110 in communication with the suction flow path 320 is formed to be adjacent to the squeeze 120, as shown in Figure 7, the squeeze 120 by one side It is preferable to inhale air from the simulated bottom lying down so that the dust and foreign matter therein can be concentrated.

Referring to the operation and effect of the suction inlet for the vacuum cleaner according to an embodiment of the present invention made of the above configuration are as follows.

First, when the user operates the vacuum cleaner, suction force is generated in the suction port body 100 by the operation of the motor 7 and the fan 8 installed in the main body 1 (Fig. 1) of the vacuum cleaner.

Therefore, air containing dust and foreign matter is sucked through the main suction port 110a formed at the bottom surface 110 of the suction port body 100 and flows into the main body 1 side through the space portion 101.

On the other hand, as shown in Figure 6, the air sucked into the housing 102 through the bypass hole 130 is introduced into the inside of the duct 210 while the floating member 220 by the flow of air up and down As the floating member 220 moves up and down, the upper plate 231 and the lower plate 232 of the vibrating member 230 are hit.

When the floating member 220 strikes the upper plate 231 and the lower plate 232 of the vibrating member 230 up and down, the vibrating plate 240 installed at the lower end of the vibrating member 230 impacts the cleaning object to vibrate. In addition, it separates dust and foreign matter from the object to be cleaned.

As such, the air sucked into the housing 102 through the bypass hole 130 to operate the vibration generating means 200 is directed to the outside of the duct 210 through the through hole 210a formed at one side of the duct 210. The air discharged to the outside of the duct 210 is introduced into the inlet side 310a of the venturi tube 310 constituting the suction force generating means, as shown in FIG. 7.

Air flowing into the inlet side 310a of the venturi tube 310 flows through the central portion of the venturi tube 310 to the outlet side 310b and then passes through the space 101 to the inside of the main body 1. Is inhaled.

At this time, the air flows through the central portion of the venturi tube 310 having a smaller cross-sectional area, and the flow rate increases, and as the flow rate of air increases, the low pressure portion having a relatively lower pressure than the adjacent side is formed.

Therefore, suction force is generated in the suction channel 320, and the air containing the foreign matter is sucked through the auxiliary suction port 321 at the bottom of the suction channel 320.

In this case, as the hair 81 of the carpet 80 is laid down by a predetermined angle on the adjacent side of the auxiliary suction port 321 by a certain angle, a gap is generated between the hair and the hair so that the dust embedded in the gap and Foreign matter is exposed to the side of the auxiliary suction port 321, it is easily suctioned with the air into the suction flow pipe 320.

The foreign matter and the air sucked into the suction flow channel 320 is sucked into the venturi tube 310 through the discharge hole 315 and then discharged into the space portion 101 through the outlet side 310b. While passing through the dust collecting bag 9 inside the main body 1, dust and foreign substances are filtered out of the dust collecting bag 9, and the air from which the dust and foreign matter have been separated is discharged to the outside of the main body 1 through the outlet 11. do.

On the other hand, the embodiment of the present invention as described above is configured to help the understanding of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope without departing from the spirit of the present invention.

As described in detail above, according to the present invention, vibration is applied to the object to be cleaned by the vibration generating means, and dust and foreign matters embedded in the hairs of the cleaning object such as carpets or blankets or the fluff by the squeeze and suction force generating means. By easily inhaling and cleaning, it is possible to easily clean not only the foreign matter on the surface of the bedding but also the inside of the hairs of the carpet or the blanket.

Therefore, the user can easily perform the cleaning operation without shaking or shaking the carpet or blanket one by one.
