Technical Field
The present disclosure relates to a cleaner (cleaner).
Background
The cleaner is a device that performs cleaning by sucking and wiping dust or foreign substances on a surface to be cleaned.
The cleaners can be classified into a manual cleaner that a user moves in person for cleaning and a robot cleaner that moves automatically for cleaning.
The manual cleaners may be classified into a canister type cleaner, an upright type cleaner, a portable type cleaner, and a stick type cleaner according to types.
A hand-held vacuum cleaner is disclosed in korean patent publication No.10-1127088 (3/8/2012), which is a prior art document.
The handheld vacuum cleaner may include a suction tube, an airflow generator, a centrifugal separation device, a power source, and a handle.
An airflow generator is disposed in the motor housing and is in the form of a motor and fan assembly. A pre-motor filter may be provided at the front of the flow generator and a post-motor filter may be provided at the rear of the flow generator.
When the motor of the hand-held vacuum cleaner is driven, an air flow can be generated along the suction pipe, and air existing around the target area to be cleaned can be sucked through the suction hole.
The foreign substances contained in the air sucked through the suction hole may be collected into an upstream cyclone (cyclone) by the centrifugal separation device. Also, the air partially cleaned by the upstream cyclone may be introduced into the downstream cyclone. In the downstream cyclone, impurities having a smaller particle size than that of the impurities collected in the upstream cyclone may be separated.
The impurities remaining in the air passing through the downstream cyclone may be discharged from the centrifugal separating device, filtered again while passing through the pre-motor filter and the post-motor filter in succession, and then discharged to the outside of the hand-held vacuum cleaner.
Here, in order to prevent the foreign substances, which are not separated from the upstream cyclone and the downstream cyclone, from being discharged to the outside, the foreign substance filtering performance of the pre-motor filter and the post-motor filter is important.
Also, as cleaning time accumulates, impurities may accumulate on the filter. The foreign substances accumulated on the filter may act as a flow resistance on a passage of the cleaner, thereby deteriorating a suction performance of the cleaner. Therefore, in order to reduce the deterioration of the suction performance of the cleaner, it is necessary to sufficiently secure the area of the filter.
In the case of the prior art, in order to increase the area of the filters, it is necessary to increase the size of the space for accommodating each filter. Therefore, there is a limitation in that the internal structure of the hand-held vacuum cleaner must be changed.

Advantageous effects
According to the proposed embodiment, the area of the filter can be increased without changing the structure of the cleaner body.
In particular, the volume of the filter may be greater than the volume of the receiving space of the filter provided in the body. Also, when accommodated in the main body, the filter may be bent to be accommodated in the accommodating space of the filter. Therefore, the area of the filter can be increased without changing the structure of the filter receiving part. Accordingly, a cleaner having effectively improved impurity filtering performance can be provided.
Since the area of the filter is increased, the total amount of impurities that can be accommodated in the filter can be increased. Therefore, it is possible to reduce the loss of the suction performance of the cleaner due to the accumulation of the cleaning time.
