When the suction force is generated in this way, the air including the foreign matter is sucked by the suction nozzle body 100, and the air including the sucked foreign matter is introduced into the dust collecting container 310 through the suction guide 312 of the dust collecting unit 300. Inflow.

In this case, the light emitting device 422 of the foreign material detector 420 projects the infrared light to the reflecting plate 410 and the light receiving element 424 detects the infrared light reflected by the reflecting plate 410 to collect the dust. The display means 500 does not emit light and maintains a flickering state.

In addition, the '┰' type tube formed in the passage shield 382 is placed in a state such as '├' as shown in FIG. 8 so that the motor connection passage 374 and the dust collecting passage 376 communicate with each other. Compression channel 378 is shielded.

The air containing the foreign matter introduced into the dust collecting container 310 through the suction guide 312 is circulated while rotating along the inner wall of the dust collecting container 310, and the foreign material having a relatively large mass is the falling portion 342. Passed through and stacked on the lower side of the separation plate 340, the foreign material having a relatively small mass rotates along the outer circumferential surface of the filter assembly 350 and is filtered by the filter assembly 350.

Air passing through the filter assembly 350 passes through the exhaust rib 322 and the dust collecting passage 376 and passes through the motor connection passage 374 to be discharged to the outside of the dust collecting unit 300. The air discharged to the outside of the dust collecting unit 300 is discharged to the outside of the cleaner through the discharge unit 290 mounted on the outer surface of the main body 200 via a motor (not shown), the cleaning is performed.

On the other hand, when a large amount of foreign matter is accumulated in the dust collector 310, the infrared rays projected from the light emitting element 422 is interrupted by the foreign matter and is not transmitted to the light receiving element 424, and short-circuited.

In this case, the light receiving element 424 applies power to the dust collection amount display means 500 through the wire 430, so that the dust collection amount display means 500 emits light. When the dust collection amount display unit 500 emits light, the user recognizes this and compresses the foreign material by operating the dust compression means P.

In order to operate the dust compression means (P), first, the control knob 384 protruding on the left side (see FIG. 3) of the main body 200 is rotated 90 degrees counterclockwise.

At this time, the flow path blocking rod 382 is also rotated at the same time as shown in Figure 9, that is, the dust collecting passage 376 is shielded and the compression passage 378 is in an open state, the compression passage 378 is The motor connection flow path 374 is in communication with.

When the change of the air flow path is completed by the operation of the control knob 384, power is supplied to a motor (not shown) generating a suction force, and the dust is collected by the separator plate 362 provided in the dust collecting unit 300. Compressed foreign material will be compressed.

The compression is transmitted to the lower portion of the dust collecting tube 310 through the suction force generated in the motor sequentially through the motor connection passage 374, the passage shielding rod 382, the compression passage 378, the compression guide portion 390. In this case, the suction force transmitted to the lower portion of the dust collecting container 310 allows the separating plate 362 to slide downward so that the bottom surface of the separating plate 362 is able to compress the collected foreign matter.

The slider 364 also flows downward while the separation plate 362 slides downward, and the separation prevention flange 364 'bent at the lower end of the slider 364 is the spring as shown in FIG. 6B. An elastic restoring force is generated in the spring S by pressing down the S.

When the foreign material inside the dust collecting container 310 is compressed, the power is cut off to the motor so that the separator 362 is returned to its original position. That is, when the power of the motor is cut off, the suction force acting on the lower part of the dust collecting container 310 is removed, and the spring S is returned to its original state and the separation preventing flange 364 'is pushed upward. The plate 362 is restored to its original state as shown in Fig. 6A.

Thereafter, the control knob 384 is rotated 90 ° clockwise again so that the passage shielding rod 382 is in a state as shown in FIG. 8. As a result, the dust compression by the dust compression means P is completed, and the compressed dust is reduced in volume so as not to interfere with the infrared rays projected from the light emitting element 422, so that the dust collection amount display means 500 blinks again. do.

Therefore, the dust collecting unit 300 is in a state in which dust collecting efficiency is improved and cleaning can be performed. In addition, the dust compression means (P) can be operated by temporarily rotating the control handle (384) even during the cleaning.

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

The vacuum cleaner according to the present invention as described above is configured so that the amount of foreign matter collected in the dust collecting unit is detected and displayed, and the foreign material can be compressed by changing the flow path by the user.

Therefore, there is an advantage that the amount of foreign matter accumulated in the dust collecting container can be recognized from the outside, thereby increasing the convenience of use.

In addition, there is an advantage that the inconvenience of having to empty the dust collected frequently during the cleaning operation by effectively utilizing the internal space of the limited dust collecting container.

In addition, by compressing the foreign material, there is an advantage that the convenience of use is increased by preventing the scattering of dust generated when emptying the foreign material.
