Embodiment Construction

[0043] The following will refer to Figures 1 to 22 A first embodiment of the present invention will be described.

[0044] figure 1 A canister type vacuum cleaner 1 is shown, which can be moved over the floor to be cleaned. The vacuum cleaner 1 includes a cleaner body 2 and a suction unit 3 . The cleaner body 2 has a plurality of wheels 2a and a connection port 2b. The wheel 2 a is rotatably supported on the cleaning body 2 . A connection port 2 b is opened at the front of the cleaner body 2 .

[0045] Such as image 3 As shown, the cleaner body 2 includes a motor-driven blower 4 . A motor-driven blower 4 is provided at the rear half of the cleaner body 2 and has an air inlet 4a and a support ring 4b. Air can be sucked into the blower 4 through the air inlet 4a. A support ring 4a made of rubber surrounds the air inlet 4a. The air inlet 4 a faces toward the front of the cleaner body 2 . The support ring 4 b is positioned on the front end of the motor-driven blower 4...

Abstract

A vacuum cleaner (1) includes a motor-driven blower (4) for drawing air and a dust-catching unit (15) for separating dust from the air drawn by the blower (4) and catching the dust separated from the air. A receptacle (23) is located between the blower (4) and the dust-catching unit (15) and holds a filter (61) for filtering the air that has passed through the dust-catching unit (15). An airflow control device (111) is arranged between the filter (61) and the blower (4). The airflow control device (111) generates a first airflow, which passes through the dust-catching unit (15) and the filter(61) and goes toward the motor-driven blower (4). The airflow control device (111) generates a second airflow, too, which bypasses the filter (61), passes through at least a part of the dust-catchingunit (15), and goes toward the motor-driven blower (4). The part of the dust-catching unit (15) is located downstream of the receptacle (23), with respect to a direction in which the second airflow goes.

Description

technical field [0001] The present invention relates to a vacuum cleaner for separating dust from air sucked by a motor-driven blower by using a dust collecting unit utilizing inertial force and a filter provided downstream of the dust collecting unit. Background technique [0002] Various electric vacuum cleaners are known, each of which separates dust from air sucked in by a motor-driven blower by using inertial forces, thus eliminating the need for a pack filter in the form of a bag. For example, a vacuum cleaner of this type is disclosed in Japanese Patent No. 3490081. [0003] The vacuum cleaner disclosed in this patent includes a cleaner body containing a motor-driven blower. The cleaner body supports the dust container. A dust collection container that can be removed from the cleaner body is placed in front of the motor-driven blower. The dust collection container has a first dust collection chamber, a decompression chamber, a separation part and a guide line. The...
