Description

本発明は、電気掃除機に関するもので、特に枠体とフィルターから構成される排気フィルターの保持方法に関するものである。   The present invention relates to a vacuum cleaner, and more particularly to a method for holding an exhaust filter composed of a frame and a filter.

従来の塵埃を集塵箱に収用するタイプの電気掃除機において、本体の外郭に設けた排気口から排気する際に極力塵埃を排出しないようにするための排気フィルターが開口部に配置されている。また、この排気フィルターは定期的にフィルターの掃除を行うために着脱自在に構成されていた。そして、この排気フィルターを容易に着脱する保持方法として、
本体の後部の排気口に設けた凹部にフィルターを収納して外郭を形成する排気カバーで覆うと共に爪嵌合で固定する構成のものや、排気口そのものはスリット状の開口部を外郭ケースと一体に形成し、上面開口部からフィルターを挿入する構成のものがあった(例えば、特許文献1参照)。
実開平4−36775号公報
In a conventional vacuum cleaner that collects dust in a dust collection box, an exhaust filter is disposed in the opening to prevent dust from being discharged as much as possible when exhausting from an exhaust port provided in the outer shell of the main body. . In addition, the exhaust filter is configured to be detachable in order to periodically clean the filter. And as a holding method to easily attach and detach this exhaust filter,
The filter is housed in a recess provided in the exhaust port at the rear of the main unit and covered with an exhaust cover that forms an outer shell, and fixed by claw fitting, or the exhaust port itself has a slit-like opening integrated with the outer case There is a configuration in which the filter is inserted from the upper surface opening (see, for example, Patent Document 1).

しかし、従来の電気掃除機の排気フィルター保持方法の内、排気フィルターを排気カバーだけで保持する方法では、排気時に排気フィルターに加わる力を全て排気カバーが受けることになる。特に、近年のモーターの高入力化や排気のクリーンさが市場のニーズとして求められる中で、排気温度や排気圧力がいっそう上昇する傾向にあり、このような条件下で排気カバーだけで排気フィルターを確実に保持するためには、排気カバーと本体部の嵌合にバネ体の弾性力で摺動するロック機構を設ける、或いはビスで固定するなど、排気カバーの保持方法が複雑で高価なものとなったり、着脱時に工具を必要とするなど使い勝手が悪くなってしまうといった課題があった。   However, in the conventional method of holding the exhaust filter only by the exhaust cover of the vacuum cleaner, the exhaust cover receives all the force applied to the exhaust filter during exhaust. In particular, as the needs of the market for higher motor input and cleaner exhaust are demanded in recent years, exhaust temperatures and exhaust pressures tend to increase further. Under these conditions, exhaust filters can be installed using only the exhaust cover. In order to securely hold the exhaust cover and the main body, the exhaust cover holding method is complicated and expensive, such as providing a lock mechanism that slides with the elastic force of the spring body or fitting with the screw. There is a problem that it is difficult to use, such as becoming a tool or requiring a tool for attachment and detachment.

また、スリット状の開口部を外郭ケース一体に形成し、上面開口部からフィルターを挿入する構成のものにおいては、この様な課題は解決できるものの排気口を本体と一体に形成する必要があり成型の金型が複雑になるといった課題が有った。   In addition, the slit-shaped opening is formed integrally with the outer case, and the filter is inserted through the upper surface opening. However, although such problems can be solved, it is necessary to form the exhaust port integrally with the body. There was a problem that the mold of the was complicated.
