Description

Electric vacuum cleaner {ELECTRIC CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having a dust separation unit, and more particularly to an electric vacuum cleaner having a cyclone dust separation unit that pivots and separates dust from air by inertial force.

Conventionally, a method of separating dust is a method of sucking and turning air containing dust from a suction port provided in a turning part provided in a tubular container, and separating dust from air by inertial force (hereinafter referred to as cyclone type). This is disclosed (for example, refer patent document 1).

The dust separator in this manner is a cyclone dust separator, and the separated dust is pivoted along the wall surface of the swing portion and transported by gravity to the dust collection chamber below the swing portion. In the vacuum cleaner provided with the cyclone dust separator, it is disclosed that the cyclone dust separator is detachable from the vacuum cleaner main body so as to discard the dust accumulated in the dust collecting chamber, and the handle for moving the vacuum cleaner main body is provided. It is disclosed that it is provided in a cyclone type dust separation part (for example, refer patent document 2).

Then, in order to transport the dust to the dust collecting chamber by using gravity while considering the use or design of the vacuum cleaner, it is necessary to tilt the turning part to be located above the dust collecting chamber, and the dust collecting chamber at the front side of the vacuum cleaner main body. It is disclosed to arrange a cyclone dust separator such that the front side is low and the rear side is high so that the suction part is provided on the rear side of the main body of the vacuum cleaner, and the suction port provided near the rear side of the main body of the vacuum cleaner is flexible. It is disclosed to connect one end of a hose body having a pressure gauge, and to support the hose body in front of the vacuum cleaner by following the hose body on the main body side surface (see Patent Document 3, for example).

However, when the cyclone dust separator is inclined and the cyclone dust separator is disposed so that the dust collecting chamber is provided at a lower position in front of the vacuum cleaner main body and a suction part is provided at a high position at the rear side, the cyclone dust separator is disposed near the rear side of the vacuum cleaner main body. A flexible hose body is connected to the provided suction port, and the hose body is supported on one side of the cyclone dust separator so that the hose body is supported from the front of the vacuum cleaner. The sieve has a poor balance with respect to the traveling direction of the vacuum cleaner main body, and the followability to the hose body of the vacuum cleaner main body is remarkably worsening.

Since the hose body is poured along one side of the cyclone dust separator, the hose body is arranged on one side of the vacuum cleaner, and the other side is exposed to the cyclone dust separator. When there is a collision with the furniture, the wall, etc., there is a problem that the hose body is broken or the cyclone dust separator is broken.

In addition, by providing a handle for moving the vacuum cleaner main body to a detachable cyclone dust separator, the cyclone dust separator can be attached and detached every time the main body of the vacuum cleaner is transported by holding the handle. ), The worst case is destroyed and the electric cleaning body falls.

In addition, there is a problem that the vacuum cleaner main body falls down when the cyclone dust separator is trying to lift the vacuum cleaner main body while holding the handle in a state where the cyclone dust separator is not fixed to the vacuum cleaner main body.

In addition, when the cyclone dust separator is removed from the main body of the vacuum cleaner and maintained, such as dust disposal, the main body of the vacuum cleaner has no moving handle, so there is a problem that it is difficult to transport it.
