Hereinafter, the operation of the vacuum cleaner dust collection unit having the above configuration will be described.

First, when the vacuum cleaner 50 is operated, a suction force is generated by the driving of a motor (not shown) built in the body 70. In this case, the outside air and the foreign matter are sucked through the bottom suction port (not shown) of the suction nozzle body 60, and the suction air and the foreign matter are suction channel 74 and the dust collecting unit 100 of the body 70. It is introduced into the dust collecting unit 100 through the suction guide 112 of the).

The foreign matter introduced into the dust collecting unit 100 is rotated inside the cyclone cylinder 110, and the foreign material having a relatively large load by the centrifugal force is moved to the lower side and accumulated in the dust container 120. That is, the relatively heavy foreign matter is first separated in the air is moved to the lower side through the gap between the dust through hole 152 and the outer peripheral surface of the separating plate 150 is stacked in the dust container 120.

In addition, the relatively fine foreign matter is separated by the dust filter 140 in the process of moving from the outside of the dust filter 140 to the inside is accumulated in the dust container 120.

The air that is purified while passing through the dust filter 140 and flows into the discharge guide passage 142 moves upward to reach the exhaust passage 132, and through the exhaust port 134, It is discharged to the exhaust passage 74 '. Air flowing through the exhaust passage 74 ′ passes through a motor (not shown) inside the body 70, and then is discharged to the outside.

Next, the user looks at the process of removing the foreign matter inside by separating the dust container 120. When power is applied from the outside and the vacuum cleaner is operated as described above, electricity flows to the coil 172 ", so the iron core 172 'becomes an electromagnet. Thus, the floating magnet 174' is driven by repulsive force. (The upper end of the iron core 172 'becomes the north pole.) When the flow magnet 174' is moved upward and the elastic protrusion 182 is pushed upward, FIG. As shown in the figure, the elastic protrusion 182 is firmly inserted into the protrusion insertion groove 124 ′, thereby preventing the dust container 120 from being removed.

When the vacuum cleaner is stopped, the power applied to the coil 172 "is also cut off at the same time, so that the iron core 172 'loses the magnetic force, and thus the floating magnet 174' is lowered by the load. (See Figure 6).

As shown in FIG. 6, when the iron core 172 ′ loses magnetic force and the flow magnet 174 ′ descends downward, the elastic protrusion 182 is supported by the elastic spring 184. Grab the handle 120 'and lower the dust container 120 downward and pull forward. In this case, the elastic protrusion 182 is lowered to a lower portion and the dust container 120 is removed by sliding forward.

Thus, the fastening bar 162 is fastening ring 116. When it is pushed upward by the fastening portion 116 "of the fastening part 116", and it is out of the fastening part 116 ", it is lowered again by the elastic force of the elastic member 164, and it will be in the state as shown in FIG. Since the fastening ring 116 is fixed to the fastening bar 162, the cyclone cylinder 110 is not detached from the body 70.

When the cyclone cylinder 110 is completely inserted into the dust collecting and mounting portion 72 by the above process, the exhaust port 134 is coupled to the exhaust passage 74 'and the suction guide 112 is the suction passage. Coupled to 74.

Next, in order to mount the dust container 120, the dust container 120 is pushed into the dust collecting part 72. At this time, since the elastic protrusion 182 is supported only by the elastic spring 184, it easily flows downward.

Accordingly, the bottom surface of the dust container 120 slides with the elastic protrusion 182, and the elastic protrusion 182 is received in the protrusion insertion groove 124 '. When the elastic protrusion 182 is accommodated in the protrusion insertion groove 124 'as described above, the dust container 120 is forced upward by the elastic force of the elastic spring 184 and thus the upper end of the dust container 120 The lower ends of the cyclone barrel 110 is to be in contact with each other.

As described above, when power is applied to the coil 172 ″, the flow magnet 174 ′ pushes the elastic protrusion 182 upward, so that the dust container 120 has the cyclone cylinder 110. Close to

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.

For example, in the above embodiment, the elastic member 164 is installed above the rear end of the detachable lever 161, but in addition to the configuration, the elastic member 164 is provided below the rear end of the detachable lever 161. It will be possible to change or to be provided near the tip of the removable lever 161.

In the above embodiment, the case where the dust collecting unit 100 is mounted and used in the upright vacuum cleaner 50 is used as an example. Of course, it can be applied to a cleaner.

The vacuum cleaner dust collecting unit according to the present invention as described above is composed of a cyclone tube for filtering foreign substances and a dust container for collecting the filtered foreign substances. Therefore, when the user wants to remove the foreign matter during use, the user can easily remove the foreign matter by separating only the dust container, and thus there is an advantage in that the user is convenient.

In addition, in the present invention, the cyclone bin and the dust bin are easily removable by the respective mounting means, and the mounting means can be operated from the front, so there is an advantage in that the work efficiency is improved. For example, the cyclone cylinder is released by the operation of pressing the detachable lever, and when the installation is completed by the operation by pushing the dust-collecting mounting portion by itself, the detachable operation becomes more convenient.

In the present invention, since the rear end of the cyclone cylinder is fixed to the body of the vacuum cleaner, the mounting of the cyclone cylinder is more effective, and the detachability of the cyclone cylinder can be operated in front of the vacuum cleaner.

In addition, the present invention has an advantage that the electromagnet is provided on the lower side of the dust container so that the dust container is in close contact with the cyclone cylinder only when the vacuum cleaner is operated, so that the dust container can be easily attached and detached.
