Benefits of technology

[0014] According to the cyclone vacuum cleaner of the present invention, since the cyclone body is hinged upon the cleaner body and opened upward, the dust receptacle can be heightened without being obstructed by the grill part. As a result, dust collecting capacity can be increased compared to a conventional art, without enlarging the size of the vacuum cleaner.

Problems solved by technology

As the dust bag fills, the vacuum cleaner effectiveness decreases, necessitating frequent emptying or replacement of the dust bag.
When replacing or emptying a dust bag, however, the user is required to handle the contaminated dust bag, which is unpleasant and unsanitary for the user.
A problem with the foregoing structure is that the dust receptacle 20 is separated by moving it vertically from the cyclone body 10.
The need to allow the dust receptacle to move vertically increases the needed size of the vacuum cleaner.

first embodiment

[0032]FIG. 3 shows a cyclone dust collector as mounted to a cleaner body according to the present invention. In this figure, a cyclone dust collector 100 is mounted to a receiving portion in the cleaner body 1 and a vacuum generator (not shown) is disposed at one side of the cyclone dust collector 100. The cyclone dust collector 100 comprises a cyclone body 110 for separating dust from drawn-in air, and a dust receptacle 120 for collecting the dust separated by the cyclone body 110.

[0033] The cyclone body 110 is attached to a partition 2 of the cleaner body 1 by a two-part hinge 113. The partition 2 constitutes the receiving portion of the cleaner body 1.

[0034] As can be seen, the cyclone body 110 is attached to (or in an alternate embodiment comprises) a first part 111 of the hinge 113 that is located (or formed) at one side of the cyclone body 110. A second hinge supporting part 112 of the hinge 113 is attached to (or in an alternate embodiment comprises) part of the partition 2 ...

second embodiment

[0039] For FIG. 5 shows the invention, which provides even greater capacity dust receptacle 120′ and which enables the dust receptacle 120′ to be detached from the cyclone body 110′ at smaller inclination angles of the cyclone body 110′ around the axis of the hinge 113. In FIG. 5, the top opening 127 of the dust receptacle 120′ and the bottom opening 117 of the cyclone body 110′ are canted or inclined with respect to each other as shown. The bottom opening 117 of the cyclone body 110′ of the dust collector 100′ is inclined at an angle that matches the inclination of the top opening 127 of the dust receptacle 120′

[0040] A distinctive feature of the second embodiment shown in FIG. 5 is that the cyclone body 110′ comprises a sloping bottom opening 117 the pitch or inclination of which matches the pitch or inclination of the opening 127 of the dust receptacle 120.′

[0041] The top opening, which is also referred to herein as a first sloping part 127, is slanted “upward” in the direction a...

third embodiment

[0045]FIG. 8 shows a cyclone dust collector mounted in a cleaner body of a cyclone vacuum cleaner. With reference to FIG. 8, a cyclone dust collector 100″ comprises a cyclone body 110″ and a dust collector 120″. As shown in FIG. 8, the cyclone body 110″ is mounted to the receiving portion of the cleaner body 1 to separate dust from drawn-in air. A dust receptacle 120″ below the cyclone body 110 collects separated dust.

[0046] As can be seen in FIGS. 8 and 9, the cyclone body 110″ is mounted to a hinged cover 5. The hinged cover 5, being hingedly attached to the cleaner body 1 by a hinge 113″, allows it to pivot or “lift” upwardly by an amount that is proportional to the angle to which the cover is rotated. Therefore, by opening the cover 5 with respect to the cleaner body 1, as shown in FIG. 9, the cyclone body 110″ is separated from the dust receptacle 120″. By closing the cover 5, the cyclone body 110″ is connected to the dust receptacle 120″, as shown in FIG. 8.

Abstract

A cyclone vacuum cleaner provides an improved capacity dust receptacle by structuring the cyclone body of the vacuum cleaner to be pivotally mounted to the vacuum cleaner body. The cyclone body is disconnected from the dust receptacle by rotating or “turning up” the cyclone body by rotating it about the pivotal mount. A dust receptacle removably mounted in the cleaner body and a cyclone body hinged on an upper part of the cleaner body are selectively separated and connected with respect to the dust receptacle.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims benefit under 35 U.S.C. § 119(a) of Korean Patent Application No. 2004-93413, filed Nov. 16, 2004, the entire contents of which are incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a cyclone-type vacuum cleaner that separates dust from drawn-in air using a cyclone dust collector. BACKGROUND OF THE INVENTION [0003] It's well known that vacuum cleaners draw in dirt and dust-laden air by a suction force created by a fan or blower within the vacuum cleaner body. Most prior art vacuum cleaners separate and collect dirt and dust using a filtration bag that is commonly known as a dust bag. As the dust bag fills, the vacuum cleaner effectiveness decreases, necessitating frequent emptying or replacement of the dust bag. When replacing or emptying a dust bag, however, the user is required to handle the cont...
