Description

  The present invention relates to a dust collector used for a vacuum cleaner and the like and a vacuum cleaner equipped with the dust collector.

  There are two methods for collecting dust in conventional vacuum cleaners, one using a disposable paper pack and the other using a reusable dust collector. Recently, vacuum cleaners using economical dust collectors Is increasing. As a dust collector with a simple structure, a dust collection case for storing dust is attached to a dust collection case so that it can freely rotate to be a lid for the dust collection case. (For example, refer to Patent Document 1).

JP 2008-22932 A

  However, in the configuration of the conventional dust collecting device, the dust collected in the dust collecting case tends to accumulate in a filter provided downstream of the suction. In particular, fine dust with a small particle size and light weight floating is the cause of clogging (deterioration of ventilation performance) to the filter, which acts on the early deterioration of the suction performance in a vacuum cleaner, In recent years, vacuum cleaners equipped with such a dust collector tend to appeal for maintenance by the user to remove fine dust attached to the filter, and an increase in the usage load including suction performance has become a problem.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a dust collector and a vacuum cleaner that reduce the amount of fine dust adhering to a filter and cause little deterioration in suction performance.

  In order to solve the above-described conventional problems, a dust collector of the present invention includes a dust collection case that communicates with a suction port of a vacuum cleaner main body and stores dust, and a filter that collects the sucked dust. At least a part of the dust case is made of a charged material, and it is possible to charge static electricity generated by suction air to the dust collection case wall surface and generate electrostatic attraction to attach and capture fine dust. Become. As a result, the amount of fine dust accumulated in the filter is reduced, and deterioration of suction performance due to clogging can be reduced.

  Moreover, the vacuum cleaner of this invention is equipped with the dust collector as described in any one of Claims 1-6, and there is little clogging of a filter and there is also little deterioration of suction performance.

  The dust collector and vacuum cleaner of the present invention can reduce the amount of fine dust accumulated in the filter and reduce the deterioration of the suction performance due to clogging.

Thus, it is possible to charge the static electricity generated by the suction air to the dust collecting case wall surface and to generate an electrostatic attractive force to attach and capture fine dust. As a result, the amount of fine dust accumulated in the filter is reduced, and deterioration of suction performance due to clogging can be reduced.

  In particular, the second invention is a dust collection case in which the dust collection case of the first invention is configured in two layers of an external wall surface part formed of an antistatic material and an internal wall surface part formed of a charging material. This outer surface eliminates the charging effect, and it is possible to prevent contamination due to dust floating outside the dust collector (inside the room space).

  In the third invention, in particular, the inner wall surface part of the second invention is made detachable from the outer wall surface part, and can be detached by a single part in which fine dust is adhered and trapped by electrostatic attraction. Therefore, when removing fine dust, various measures such as washing with water can be realized.

  In the fourth invention, in particular, only the lower side of the dust collection case according to any one of the first to third inventions is formed of a charging material, and the dust collection case is formed of a transparent material so that accumulated dust inside can be seen. In such a case, since the adhesion of fine dust on the upper side is suppressed, the above effect can be achieved while ensuring the internal visibility.

  In the fifth invention, in particular, at least the inner surface of the inner wall surface part of any one of the second to fourth inventions is formed in a non-planar shape having a concavo-convex portion. Performance is improved.
