Description

The present invention relates to a vacuum cleaner. More specifically, the present invention relates to a cyclone type vacuum cleaner that separates dust from intake air using a cyclone dust collector.

It is well known that vacuum cleaners suck in debris and air containing dust through a suction force created by a fan or blower located inside the vacuum cleaner body. Most known vacuum cleaners separate and collect dust and debris using a filter bag known as a dust bag. As the dust bag fills, the efficiency of the vacuum cleaner decreases, making it necessary to frequently empty or replace the dust bag. When replacing or emptying the dust bag, the user needs to take the contaminated dust bag with his hands, which is unpleasant and unhygienic for the user.

In order to get rid of the problems inherent in dust bags of known vacuum cleaners, cyclone dust collectors have been developed and their use has become widespread. As you know, cyclone dust collectors provide high cleaning efficiency and semi-permanent use by simply removing the dust collector and discarding its contents.

Figure 1 shows a cross section of a known cyclone dust collector and its attachment or attachment to the main body of the vacuum cleaner. As can be seen from figure 1, the cyclone dust collector includes a cyclone body 10 for separating dust from the intake air, a dust collector 20 for collecting dust separate from the cyclone body 10, and a connecting element 30 for connecting to and separating from the dust collector 20 with respect to the cyclone body 10.

As is known, the cyclone body 10 has a channel, an intake air stream or a “suction channel” (not shown in FIG. 1 for image clarity) on one side thereof, which is in fluid communication with a suction brush (not shown). Dust-saturated air is sucked into the cyclone body 10 through the intake air channel from the surface being cleaned. The suction air duct is preferably shaped so that the dust-saturated air is sucked in tangentially to the side walls of the cyclone body 10 in order to facilitate the creation of a swirling air flow inside the cyclone body 10. The air drawn in through the suction channel moves along the inner wall of the cyclone body 10 and thus forms a swirling air stream that separates dust and debris by centrifugal force acting on the suspended particles as they rotate in the cyclone body 10.

The cyclone body 10 has an air outlet 12 in fluid communication with a vacuum generator (not shown). After separating dust and debris from the sucked air by centrifugation in the cyclone body 10, the filtered air is discharged out of the vacuum cleaner body 1 through the air outlet 12 and a vacuum generator. Dust and debris separated from the intake air in the cyclone body 10 are collected in a dust collector 20 connected to the bottom of the cyclone body 10.

As the dust collector 20 is filled with dust and debris, the efficiency of the vacuum cleaner deteriorates. In order to maintain the effectiveness of the vacuum cleaner, it is necessary to empty the dust collector 20. To empty the dust collector 20, the connecting member 30 located below the dust collector 20 is first turned or rotated to make it possible to separate the dust collector 20 from the cyclone body 10. After the dust receptacle 20 is separated from the cyclone body 10, the user can remove the dust receptacle 20 from the vacuum cleaner body 1 and dispose of the contents of the dust receptacle 20.

To reinstall the dust collector 20 in the vacuum cleaner body 1 after emptying it, the dust collector 20 is again connected to the connecting element 30, and the connecting element 30 is rotated in the opposite direction. Thus, the dust collector 20 can be connected to the bottom of the cyclone body 10.

The problem with the above construction is that the dust collector 20 is separated by moving it vertically from the cyclone body 10. Therefore, you need a place for vertical movement of the dust collector 20 in order to ensure its removal and installation. The need to ensure vertical movement of the dust collector increases the required size of the vacuum cleaner. In the case of a cyclone body 10 with filtering debris or a separating grate, a much larger vertical space is needed to move the dust collector 20 so that the grating element does not interfere with the dust collector 20 during its separation. Accordingly, the space for installing the cyclone dust collector increases. In order to make a vacuum cleaner using the known cyclone body 10 small enough and having a proper dust collecting capacity, a trade-off is needed between the size and the dust container.

Although not shown, some cassette-type vacuum cleaners have a design in which the dust collector can be installed or separated without vertical movement. However, in this case, the filter grate should not protrude outward from the cyclone body in order to prevent the grating element from creating interference during the separation of the dust collector. Therefore, the dust collector has compact dimensions.

In the known cases 10 of cyclone dust collectors, when the capacity of the dust collector is not large, it is often necessary to empty the dust collector 20. Therefore, it is preferable that the dust collector 20 has as much capacity as possible. However, in order to increase the volume of the dust collector 20, it is necessary to accordingly increase the overall size of the vacuum cleaner 1.

Thus, the technical task of the present invention was the creation of a cyclone vacuum cleaner, which provides an increase in the capacity of the dust collector, but which also reduces the overall size of the vacuum cleaner, is an improvement over the prior art.

This technical problem is solved by creating a cyclone vacuum cleaner containing a vacuum cleaner body, a dust receiver installed in the vacuum cleaner body and a cyclone body pivotally attached to the vacuum cleaner body above the dust receiver for selectively connecting to or disconnecting from the dust receiver by rotating about the hinge axis in which the dust receiver is installed according to the invention with the possibility of separation from the vacuum cleaner case by horizontal movement relative to it after disconnecting the dust receiver from the qi case a clone.

Preferably, the cyclone body is rotatable about an axis of the hinge at angles between approximately 5-90 °.

In a cyclone vacuum cleaner, a first beveled part can be formed additionally on the upper edge of the dust collector, tilted upward in the direction of separating the dust collector from the vacuum cleaner body, and a second beveled part is formed on the lower edge of the cyclone body, the inclination of which corresponds to the inclination of the first beveled part.

Preferably, the first mowed part of the dust collector has such an angle of inclination that when the cyclone body is turned upward, it does not interfere with its highest part.

The cyclone vacuum cleaner may further include an installation guide made in the vacuum cleaner body to control the installation and removal of the dust collector.

Preferably, the cyclone body comprises a multi-cyclone dust collector.

Preferably, the distance from the cyclone body to the hinge is such that the cyclone body moves substantially vertically with respect to the dust collector.

Technical problems are also solved due to the fact that the cyclone vacuum cleaner according to the invention comprises a vacuum cleaner body with a hinged lid, a vacuum cleaner body attached to the lid, and a dust collector attached to the vacuum cleaner body with a possibility of separation from it by horizontal movement relative to the vacuum cleaner body after disconnecting the television receiver from the housing cyclone and connected to the cyclone body by closing the cover and detachable from the cyclone body by opening the cover.

Preferably, in the cyclone vacuum cleaner, a first beveled portion is additionally formed on the upper edge of the dust collector, tilted upward in the direction of separating the dust collector from the vacuum cleaner body, and a second beveled part is formed on the lower edge of the vacuum cleaner body, the inclination of which corresponds to the inclination of the first beveled part.

Preferably, the first mowed part of the dust collector has such an angle of inclination that when the cyclone body is turned upward, it does not interfere with its highest part.

The cyclone vacuum cleaner may further comprise an installation guide portion formed in the vacuum cleaner body for controlling installation and removal of the dust collector.

Preferably, the cyclone body contains multicyclones.

The aforementioned aspect and other features of the present invention will become more apparent through the detailed description of exemplary embodiments with reference to the accompanying drawings, in which:

Below, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. The materials described, such as detailed construction and elements, are examples to facilitate understanding of the invention. Well-known functions or constructions are not described in detail since they will clutter the invention with unnecessary details.

Figure 2 shows the concept of a cyclone dust collector of a cyclone vacuum cleaner in accordance with an embodiment of the present invention. Since the design of the vacuum cleaner body is well known to specialists in this field of technology and does not apply to the disclosed and claimed invention, the design of the vacuum cleaner body is for the most part not shown in the drawings for clarity, and a further description of the vacuum cleaner is not included in the description for brevity.

In the structure shown in FIG. 2, the dust receptacle 102 is removably mounted on the cyclone body 101, which, in turn, is mounted on the vacuum cleaner body (not shown) by a pivot axis or hinge 103, which is located at a predetermined distance L from the housing the cyclone 101. By rotating the cyclone body 101 (clockwise, as shown) around the axis of rotation or the hinge 103, the dust collector 102 can be connected and separated from the cyclone body 101.

Specialists in the art will understand that, as shown in the drawings, for a given angle θ, measured between the plane of the upper surface 106 of the cyclone body and the horizontal 107, the cyclone body 101 rises above the dust collector 102 by rotating the cyclone body 101 around the axis of the hinge, which connects the cyclone body 101 to the vacuum cleaner body. The vertical distance 104 by which the cyclone body 101 rises or can be "raised" above the dust collector 102 is approximately equal to the trigonometric expression L x (sinθ). It can be seen from this expression that for a given rotation angle θ, increasing the distance L by which the cyclone body 101 is removed from the rotation axis 103 increases the vertical lift 104 of the cyclone body 101 above the dust collector 102 to ensure ease of installation and separation of the dust collector 102 from the cyclone body 101.

As described above, since the cyclone body 101 is rotated on a hinge 103 mounted on the cleaner body, the dust collector 102 is not interrupted by the grating element 105 protruding from the center of the cyclone body 101 during installation and separation of the dust receptacle 102 from the cyclone body 101. Accordingly, the dust collector 102 can be made larger than would be possible using the known structures shown in FIG. 1.

Figure 3 shows a cyclone dust collector attached to a dust collector body in accordance with a first embodiment of the present invention. In this drawing, a cyclone dust collector 100 is attached to a receiving part in the vacuum cleaner body 1, and a vacuum generator (not shown) is located on one side of the cyclone dust collector 100. The cyclone dust collector 100 includes a cyclone body 110 for separating dust from the intake air and a dust collector 120 for collecting dust, separated by a cyclone body 110.

The cyclone body 110 is connected to the partition 2 of the cleaner body 1 by a hinge 113 consisting of two parts. The partition 2 forms the receiving part of the cleaner body 1.

As you can see, the cyclone body 110 is attached to (or in an alternative embodiment includes) a first part 111 of the hinge 113, which is located (or formed) on one side of the cyclone body 110. The second hinge-bearing part 112 of the hinge 113 is connected to (or in an alternative embodiment comprises) part of the partition 2 of the vacuum cleaner body 1. The first hinge part 111 and the hinge-bearing part 112 are arranged so that the dust collector 120 does not interfere with the outer periphery of the cyclone body 110 and the lattice element 115 formed in the cyclone body 110 when the dust collector 120 is separated by rotating the cyclone body 110 about the axis of the hinge 113 by a predetermined angle. More specifically, the first bearing part 111 and the bearing bearing part 112 are dimensioned and arranged so that the cyclone body 110 can rotate around the axis of the hinge 113 by approximately 5-90 ° with respect to the plane in which the upper opening of the dust collector 120 is located. Cyclone rotation angle 110 is determined in accordance with the designs of the cleaner body 1 attaching the cyclone dust collector 100 and the dust collector 120.

Although not shown in FIG. 3, the cyclone body 110 comprises a suction air channel in fluid communication with a suction brush of a vacuum cleaner that moves along or contacts a surface to be cleaned. The air outlet is in fluid communication with a vacuum generator. Therefore, dust-saturated air is sucked in by the suction brush from the surface to be cleaned and sent to the cyclone body 110 through the intake air channel. Air from which dust is removed by centrifugation in the cyclone body 10 is discharged out of the vacuum cleaner body 1 through an exhaust channel and a vacuum generator. Since the design of the cyclone body 110 for suction of dust-saturated air, dust separation and the release of purified air are not the essence of the present invention, their detailed description will be omitted hereinafter.

The dust collector 120 is connected to the bottom of the cyclone body 110 so as to collect dust separated from the dust-saturated air by the cyclone body 110. The dust collector 120 is removably attached to the receiving portion of the cleaner body 1 below the cyclone body 110. When the cyclone body 110 rotates, i.e. rotates clockwise around the axis of the hinge 113, the upper part of the dust collector 120 is separated from the cyclone body 110. Also by turning down the cyclone body 110, i.e. counterclockwise rotation, the upper part of the dust collector 120 can be easily re-attached to the lower part of the cyclone body 110.

On the lower support column 3 of the receiving part of the cleaner body 1 to which the dust collector 120 is attached, an installation guide 130 may be provided to control the installation and separation of the dust collector 102 and stabilize the position of the dust collector 120.

Choosing the configuration of the cyclone body 110, mounted on the vacuum cleaner body 1 and rotatable around the axis so that its rotation around the axis causes the cyclone body to rise, as shown in FIG. 4, the total height of the dust collector 120 can be increased by a distance h compared with the height that is possible when using a dust collector in accordance with the prior art shown in figure 1. Accordingly, the capacity of the dust collector 120 can be increased.

FIG. 5 shows a second embodiment of the invention, which provides an even larger dust collector 120 ′ and which allows the dust collector 120 ′ to be disconnected from the cyclone body 110 ′ at smaller angles of inclination of the cyclone body 110 ′ about the axis of the hinge 113. In FIG. 5, the upper opening of the dust collector 120 'and the lower hole 117 of the cyclone body 110' are beveled with respect to each other, as shown. The lower hole 117 of the cyclone body 110 ′ of the dust collector 100 ′ is beveled at an angle that corresponds to the inclination of the upper opening of the dust collector 120 ′.

A distinctive feature of the second embodiment shown in FIG. 5 is that the cyclone body 110 ′ comprises a beveled bottom opening 117, the inclination or bevel of which corresponds to the inclination or bevel of the opening 127 of the dust collector 120 ′.

The upper hole, which is also referred to here as the first beveled portion, is beveled “upward” in the direction from the cleaner body 1. The dust receptacle 120 'can thus be separated from the vacuum cleaner body 1 for emptying by horizontal “left” movement, as shown, from the vacuum cleaner body 1 in the direction A in FIG. 5.

As shown, the beveled bottom opening 117 formed on the lower edge of the cyclone body 110 ′ has a corresponding slope that corresponds to the first beveled portion 127 so that the cyclone body 110 ′ and the dust collector 120 ′ can be in close contact with each other. The angle of inclination of the first beveled part 127 is determined so that the highest part of the dust collector 120 '(referring to FIG. 5, the left side of the first beveled part 127) does not interfere with the cyclone body 110', and especially the lattice element 115 formed in the center of the cyclone body 110 ' .

Removing the dust collector 120 'and replacing it is simple. When the dust collector 120 ′ is filled with dust and needs to be emptied, the user lifts the cyclone body 110 ′ upward by turning the cyclone body 110 ′ by a hinge 113 by a predetermined angle, as shown in FIG. 6. When the cyclone body 110 ′ is rotated or rotated upward, the cyclone body 110 ′ does not interfere with the dust collector 120 ′. Therefore, the user can empty the dust collector 120 ′ by simply moving the dust collector 120 ′ to the sides or horizontally in the direction shown by the arrow in FIG. 7.

After emptying the dust collector 120 ′, the user reattaches the dust collector 120 ′ to the receiving portion of the cleaner body 1 by simply moving the dust collector to the right to the position shown in FIG. 6. A mounting guide 130 formed on the lower baffle 3 of the cleaner body 1, where the dust receptacle 120 ′ helps align the dust receptacle 120 ′ directly below the cyclone body 110 ′ when the housing 110 ′ is rotated downward. When the user lowers or swivels the cyclone body 110 ′ after the dust collector 120 ′ has been replaced, the second beveled portion 117 of the cyclone body 110 ′ comes into contact with the first beveled portion 127 of the dust collector 120 ′, as shown in FIG. 5, thereby enabling reuse vacuum cleaner.

On Fig shows a third embodiment of a cyclone dust collector mounted in the housing of a cyclone vacuum cleaner. As can be seen in FIG. 8, the cyclone dust collector 100 ″ comprises a cyclone body 110 ″ and a dust collector 120 ″. As shown in FIG. 8, the cyclone body 110 ″ is attached to the receiving portion of the vacuum cleaner body 1 to separate dust from the intake air. A dust collector 120 '' below the cyclone body 110 collects the separated dust.

As can be seen in FIGS. 8 and 9, the cyclone body 110 ″ is attached to the hinge cover 5. The hinge cover 5, which is hinged to the vacuum cleaner body 1 by a hinge 113 ″, allows it to be rotated or “raised” by a value proportional to the angle on which the cover rotates. Therefore, by opening the cover 5 relative to the cleaner body 1, as shown in FIG. 9, the cyclone body 110 ″ is separated from the dust collector 120 ″. By closing the cover 5, the cyclone body 110 ″ is connected to the dust collector 120 ″, as shown in FIG.

The dust collector 120 ″ is connected to the lower part of the cyclone body 110 ″ and is mounted with the possibility of extraction in the receiving part of the vacuum cleaner housing 1 below the cyclone housing 110 ″. With cover 5 open, the upper part of the dust collector 120 ″ is separated from the cyclone body 110 ″. With cover 5 closed, the upper part of the dust collector 120 ″ is attached to the lower end of the cyclone body 110 ″.

On the lower partition 3 of the receiving part of the vacuum cleaner body 1, where the dust collector 120 ″ is installed, the installation guide 130 fixes the position of the dust collector 120 ″ when it is moved from the lower partition 3 and back.

10 shows a cassette-type vacuum cleaner using a cyclone dust collector in accordance with a third embodiment of the present invention. During the cleaning process, the suction force generated by the vacuum generator sucks the dust-saturated air into the cyclone body 110 ″ through a suction brush (not shown) communicating in fluid with the suction pipe 9. The dust-saturated air that is sucked into the cyclone housing 110 ″ forms a vortex air flow and separates the dust that is contained in the air. The separated dust is lowered into a dust collector 120 ″ connected to the bottom of the cyclone body 110 ″. The air from which the dust was removed through the housing 110 ″ of the cyclone is discharged from the housing 1 of the vacuum cleaner through a vacuum generator 7.

When the dust collector 120 ″ is filled with dust as a result of the above processes, the dust collector 120 ″ must be separated from the housing 1 of the vacuum cleaner for emptying.

For this, the user opens the cover 5 of the housing 1 of the vacuum cleaner, thus separating the housing 110 ″ of the cyclone from the dust collector 120 ″. In this state, the user can pull out the dust collector 120 ″ from the cleaner body 1, remove dust accumulated in the dust collector 120 ″, and reinstall the dust collector 120 ″ in the cleaner housing 1. Then, by closing the cover 5, the cyclone body 110 ″ is connected to the dust collector 120 ″, as shown in FIG. 8, and therefore, the user can again clean. In other words, the user can attach and detach the housing 110 ″ relative to the dust collector 120 ″ simply by closing and opening the cover 5.

11 schematically shows a multi-cyclone dust collector as a fourth embodiment of the present invention installed in a vacuum cleaner. With the exception of the use of the multi-cyclone dust collector 200, other designs, such as the swivel connection between the cyclone body 210 and the vacuum cleaner body 1 via the hinge 211 and the mounting and separation structures of the dust collector 220, remain the same as in the previous embodiments. Therefore, this embodiment will not be described in detail.

Although the invention has been shown and described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made to the form and details without departing from the spirit and scope of the invention as defined by the appended claims.
