Benefits of technology

The present invention provides an electric vacuum cleaner and a dust collecting apparatus with improved efficiency, convenience, and ease of removing dust. The electric vacuum cleaner has a main body with an electric fan and a removable dust collecting apparatus. The dust collecting apparatus has a suction port, a cyclonic flow path, a dust collecting chamber, an air outlet port, and a filter. The main body has an opening smaller than the air outlet port for feeding air downstream by the electric fan. The air outlet port has a region opposed to the opening and a guide passage for guiding air discharged from the region of the air outlet port not opposed to the opening towards the opening. The electric vacuum cleaner can selectively use the cyclonic dust collecting apparatus or a disposable dust collecting apparatus with a mouth cardboard and a filter bag attached to the mouth cardboard. The main body has an accommodating portion for accommodating either of the dust collecting apparatuses, and the accommodating portion has a fixing member for fixing the disposable dust collecting apparatus when it is mounted in the main body.

Problems solved by technology

However, the electric vacuum cleaners of this type are uneconomical and disadvantageous in terms of environmental protection, because the cleaners utilize the disposable filter.
Further, the disposable filter is not replaced until a certain amount of dust is collected in the filter.
With the electric vacuum cleaner including the cyclonic dust collecting apparatus, however, it is cumbersome to detach the dust collecting apparatus and discard the collected dust whenever the cleaning operation is performed.

Abstract

In an inventive electric vacuum cleaner, a filter 20 through which air discharged from an air outlet port 19 is passed is provided on a rear face of a casing 18 of a cyclonic dust collecting apparatus 7, and held by a filter holder 18B. A rear face of the filter 20 is spaced from vertical ribs 32A of the filter holder 18B to define a guide passage 35 for guiding air discharged from a portion of the air outlet port 19 not opposed to an opening 33 through the filter 20 toward the opening 33. The guide passage 35 allows the air to pass through the portion of the air outlet port 19 not opposed to the opening 33.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an electric vacuum cleaner and a cyclonic dust collecting apparatus to be mounted in the electric vacuum cleaner. [0003] 2. Description of the Related Art [0004] Electric vacuum cleaners include, for example, a main body having an electric fan, a suction member to be moved along a floor surface, and a connection hose which connects the suction member to the main body, and a disposable filter bag is mounted in the main body. When an electric vacuum cleaner of this type is driven, outside air (air on the floor surface) is sucked from the suction member by driving the electric fan provided in the main body, and taken into the main body from a suction port of the main body through the connection hose. An inlet of the disposable filter provided in the main body communicates with the suction port. When the air sucked from the suction port passes through the disposable filter, dust entraine...
