PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name and Address of Applicant: Actual Inventor(s): Address for Service: Invention Title: Samsung Gwangju Electronics Co., Ltd., of 271, Oseondong, Gwangsan-gu, Gwangju-city, Republic of Korea (South) Seuk-hyeon Ju Spruson Ferguson St Martins Tower Level 31 Market Street Sydney NSW 2000 (CCN 3710000177) Vacuum Cleaner The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845c [R:\LIBW] I 3874.doc:saa -1- VACUUM CLEANER Background of the Invention Field of the Invention The present invention relates generally to a vacuum cleaner, and more specifically to a vacuum cleaner is capable of preventing the air exhausted from the motor from flowing directly to the air outlet.
Description of the Related Art In general, a vacuum cleaner has a suction brush connected to a cleaner body, the suction brush being movable along a surface so as to clean it. The cleaner body accommodates a dust collecting chamber in which a dust filter or a cyclone dust collector is mounted. The cleaner body also accommodates a motor driving chamber in which a motor is disposed to generate and provide suction force for driving the vacuum cleaner and generating a vacuum in the dust collecting chamber.
A suction port is typically disposed at a leading edge of the motor in the motor driving chamber, and is connected to provide fluid communication with the dust collecting chamber. Conventionally, an exhaust port is formed at a side of a motor housing, through which the air is exhausted. The air exhausted through the exhaust port is directed to a motor housing enclosing the motor and is discharged to the outside through an air outlet of the cleaner body.
In the above structure and configuration, when the motor is mounted in the motor driving chamber, some parts of the motor are covered by the cleaner body and the motor housing. Accordingly, the air exhausted through the exhaust port of the motor housing is directed to the motor housing and is discharged to the outside environment through the air outlet of the cleaner body.
However, when the motor rotates at high speed, noise is generated and is released to the outside environment together with the discharged air. If the structure of the motor driving chamber, which is configured with the cleaner body and the motor housing, only covers the motor, the air discharge path is shortened and noise is not efficiently reduced.
[R:\LIBLL] 15 82lspeci.doc:KEH -2- Object of the Invention It is an object of the present invention to overcome or ameliorate some of the disadvantages of the prior art, or at least to provide a useful alternative.
Summary of the Invention s The present invention at least in a preferred embodiment provides an improved vacuum cleaner capable of reducing noise generated within a motor driving chamber by extending the air discharge path of the motor driving chamber.
The vacuum cleaner preferably includes a cleaner body having a motor driving chamber having an air inlet and an air outlet, a motor disposed in the motor driving io chamber for drawing in air through the air inlet and exhausting the air into the motor driving chamber, and a motor housing disposed in the cleaner body to cover the motor and defining the motor driving chamber, the motor housing having air guide ribs for preventing the air exhausted from the motor from directly flowing to the air outlet.
Preferably, the motor driving chamber is further defined by the engagement of a lower housing having the air inlet and the air outlet and being integrally formed with the cleaner body, and the motor housing engaged to cover an open upper part of the lower housing.
The air is exhausted from the motor toward the motor housing. The air guide ribs may include at least one first rib for changing direction of the exhaust air flow from the motor to flow in a first direction, and at least one second rib for preventing the air flowing in the first direction from mixing with air flowing in a second direction, opposed to the first direction, thereby to extend the air flow path.
The first ribs are formed extending downwardly from the motor housing into the motor driving chamber, opposite to each other and separated by a predetermined interval.
A pair of second ribs is formed extending downwardly from the motor housing into the motor driving chamber in a parallel relationship to each other, and extending substantially perpendicular to the first ribs. The first and second ribs arc arranged and oriented to cooperate with each other and so to provide a baffle to the air flow within motor driving chamber.
[R:\LIBLL] 15821 speci.doc:KEH A partition rib is formed projecting upwardly from the lower housing of the motor driving chamber in a corresponding location so as to engage the first rib so that the motor does not directly face the air outlet.
A pair of the second ribs may be formed to extend from the motor housing to the bottom of the lower housing in a parallel relationship to each other.
Brief Description of the Drawings A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, wherein: FIG. 1 is a perspective view in partial cross-section illustrating a portion of a 1o vacuum cleaner according to an embodiment of the present invention; FIG. 2 is a perspective view illustrating the motor housing also shown in FIG. 1; and FIG. 3 is an elevational view illustrating the main parts of FIG. 1, in which the air flow path is represented by a dashed line.
Detailed Description of the Preferred Embodiments Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by reference to the drawing figures.
Referring now to FIG. 1, a vacuum cleaner according to an embodiment of the present invention includes a cleaner body 10 having a motor driving chamber 11, a motor disposed in the motor driving chamber 11, and a motor housing 30 disposed in the cleaner body 10 to cover the motor The motor driving chamber 11 has an air inlet 11 a, through which air is drawn in by the suction force generated by the motor 20, and an air outlet I lb, through Which the air in the motor driving chamber 11 is discharged to the outside environment. The air inlet 1 la and the air outlet 1 lb are disposed to oppose each other, and the motor 20 is disposed generally between the air inlet 1 la and the air outlet 1 lb.
[R:\LIBLL] 15821 speci.doc:KEH -4- A motor driver housing 21 covers the driving part of the motor 20. Hence, a leading edge of the motor driver housing 21 is directly connected to the air inlet 1 la to draw the air into the motor driver housing 21. An exhaust port 21 a is formed at a side of the motor driver housing 21, for example, the topside, as shown, through which the drawn air is exhausted from the motor 20. According to an embodiment of the present invention, the exhaust port 21a is formed to face upwardly so as to face the motor housing The motor driving chamber 11 is provided to accommodate the motor 20 and is divided from a dust collecting chamber (not shown) by the air inlet la. The dust collecting chamber may accommodate a dust bag or a cyclone dust collector, both of which are well known to those skilled in the art. According to an embodiment of the present invention, the motor driving chamber 11 is shaped and configured so that a predetermined space is formed by cooperation of a lower housing 13, which may be integrally formed with the cleaner body 10, as shown, and the motor housing 30, which may be a separable element.
The lower housing 13 is shaped to form a bottom wall and sidewalls of the motor driving chamber 11. The motor housing 30 is connected to cover the open part of the motor driving chamber 11, that is, the upper part of the motor The motor housing 30 preferably has air guide ribs 31, 33 disposed adjacent the motor 20 to prevent the air exhausted from the exhaust port 21a from directly flowing to the air outlet 1 lb.
Referring to FIG. 2, the air guide ribs include at least one first rib 31 and at least one second rib 33. The first rib 31 is integrally formed with the motor housing 30 by extending downwardly for a predetermined dimension. The first rib 31 initially changes the flow direction of the air exhausted from the air inlet IlIa. For this, the first rib 31 faces the air outlet 1 lb and is spaced at a predetermined distance from the air outlet 1 lb.
As a result, the air discharged from the air inlet 1 la is directed toward the first rib 31 by housing body 30a and is reversed by the first rib 31 in the direction A, shown in FIG. 1 by the broken lines.
[R:\LIBLL 15821 speci.doc:KEH Referring again to FIG. 1, it is preferred that the lower housing 13 includes a partition rib 13a, which is projected upwardly to engage the corresponding first rib 31.
The upper end of the partition rib 13a contacts with the lower end of the first rib 31 to seal the space therebetween. Hence, the motor 20 does not directly face the air outlet I lb and the discharging flow path of the air is extended by the baffles resulting from the partitions.
The second rib 33 directs the air flow so that the air reversed by the first rib 31 in the direction shown by arrow A does not mix with the air flowing in the opposite direction, shown by arrow B. A pair of the second ribs 33 extends downwardly from the l0 housing body 30a and extend parallel to each other. The second ribs 33 also extend from both ends of the first rib 31 so as to end in proximity to the bottom of the motor driving chamber 11, as shown. Accordingly, the air flow is reversed by the first rib 31 in the direction of arrow A and is directed toward the air outlet 11 a by the obstruction provided by inner sides 33a of the second ribs 33 (FIG. The inner sides 33a face each other, as best seen in the plan view of FIG. 3. After passing around the inner sides 33a, the air flow is reversed in the direction shown by arrow B by the outer sides 33b of the second ribs 33 and the air is then directed toward the air outlet 1 lb.
The operation of the vacuum cleaner according to an embodiment of the present invention is described below in greater detail.
Referring to FIG. 3, when the motor 20 is driven, the air is drawn in toward the air intake port of the motor 20. The drawn in air is exhausted toward the housing body of the motor housing 30 through the exhaust port 21a. The air exhausted through the exhaust port 21a is directed by the housing body 30a and flows toward the first rib 31.
Next, the air flow is reversed by the first rib 31 since the air has nowhere else to go, and is directed, along the inner side 33a of the second rib 33, and flows back toward the air intake port of the motor The air is reversed to flow in the direction of Arrow B in the motor driving chamber 11, which is sealed, and is directed by the outer side 33b of each second rib 33 so as to flow toward the air outlet 1 Ib, and is then discharged to the outside environment.
[R:\LIBLL] 15821 speci.doc:KEH -6- As described above, in the vacuum cleaner according to the embodiment of the present invention, the air flow path, along which the air exhausted from the motor flows, is forced to follow in a zigzag, or substantially zigzag, pattern, a path as in a baffle so as to extend the length of the air flow path. Hence, when the motor 20 is driven, the noise of the discharged air is significantly attenuated by the extended length of the air flow path.
In the embodiment of the present invention, the ribs 31 and 33 are integrally formed with the motor housing 30, as shown in FIG. 2, but the invention is not limnited to this embodiment. The ribs may be separately manufactured for assembly into the motor driving chamber 11 and may be connected or sealed relative to the housing 30. In 1o addition, the ribs may be integrally formed with the bottom of the motor driving chamber 11, that is, being integrally formed with the lower housing 13.
In the vacuum cleaner according to the embodiment of the present invention, the ribs are formed so that the air flow path, along which the air is exhausted from the motor driving chamber 11, is extended to thus attenuate the noise during discharge as the air is discharged to the outside environment.
Furthermore, the direction of the air flow path can be controlled in a simple way since the air guide ribs are preferably integrally formed with the motor housing of the motor.
While the preferred embodiments of the present invention have been described, additional variations and modifications of the embodiments may occur to those skilled in the art once the basic inventive concepts are understood. Therefore, it is intended that the appended claims shall be construed to include both the above embodiments and all such equivalents, variations and modifications that fall within the spirit and scope of the invention, as defined by the following claims.
