BACKGROUND OF TI3E INVF,NTION
1. Field of the Invention The present invention relates generally to an upright type vacuum cleaner, and more particularly to a suction brash for an upright type vacuum cleaner that draws imair including dust and contaminants, while moving along a surface to be cleaned.
BACKGROUND OF TI3E INVF,NTION
1. Field of the Invention The present invention relates generally to an upright type vacuum cleaner, and more particularly to a suction brash for an upright type vacuum cleaner that draws imair including dust and contaminants, while moving along a surface to be cleaned.
2. Description of the Related Art As shown in FIG.1, an upright type vacuum cleaner generally comprises a suction I0 brush 20 that is connected to a cleaner body 10 and moves along a surface to be cleaned.
The cleaner body 10 is divided into a dust collecting chamber 11 where a dust filter (not shown) is removably disposed and a motor driving chamber 12 where a motor for generating a suction force is disposed. The dust collecting chamber l l is opened and closed by a cover I3.
Additionally, provided in the suction brush 20 is a brush bar 21 for brushing contaminants off the surface to be cleaned, while being exposed at a lower portion of the suction brush 20: The brush bar 21 is rotated by a rotation force that is transmitted from the motor disposed in the motor driving chamber 12 via a driving force transmission belt 23 (shown in phantom).
In the above construction, when the motor is driven, a strong suction force is generated at a lower part of the suction brush 20. Due to the suction force, the ate, including dust and contaminants entrained therein, is drawn into the dust collecting chamber, l I of the cleaner body 10 from the cleaning surface.
The rotation force is also transmitted from the motor to the brush bar 21 via the driving force transmission belt 23. The brush bar 2Z rotates and brushes the contaminants off . CA 02384212 2002-04-30 EL693134o43US
of the surface to be cleaned; thereby removing the contaminants from the surface to be cleaned, whereby the removed contaminants are also drawn into the dust collecting-chamber 11.
Meanwhile; the drawn air flows'into a dust filter (not shown) disposed in the dust collecting chamber l 1. At thin point, various contaminants entrained in the air are filtered through the dust filter and the air is discharged out through the motor driving chamber 12.
However, the upright type vacuum cleaner as constructed above has a problem of contamination of the driving force transmission belt 23 where the dust and contaminants are inadvertently transferred from the brush bar 21. Especially, when foreign matted such as hair or string; is caught in the driving force tran~nission belt 23, the driving force is not efficiently transmitted to the brush bar 21 and thus can not rotate flee brush bar 21. Also, there may be an occasion that the driving force transmission belt 23 is cutduring operation.
Since it is necessary to check for contamination and the condition of the driving force transmission belt 23, the suction brush 20 has to be separated from the vacuum cleaner.
Therefore, an inconvenience arises since .the condition of the driving force transmission belt I S 23 and the motor has to be checked.
The present invention is developed iri order to solve the above problems.
Accordingly, it is an object of the present invention to provide a suction brush for an upright type vacuum cleaner having an improved construction enabling easy checking of the condition of the driving force transmission belt of the suction brush.
The above object is accomplished by providing a suction brush for an upright type vacuum cleaner according to the present invention: According to the present invention; the suction brush is rotatably disposed and attached to a cleaner body to move along a surface to be cleaned, for drawing in contaminants from the surface to be cleaned by a uction force generated from a motor driving chamber disposed at a lover portion of the cleaner body comprising a suction brush body, a brush bar rotatably disposed inside the suction brush body for brushing the contaminants from the surface to be cleaned, a driving force transmission S belt disposed inside the suction brush body for transmitting a rotation force to the brush bar from a motor of the motor driving chamber; and a belt checking cover pivotably disposed at a lower portion of the suction brush body to check for contamination and the condition of the driving force transmission belt.
It is preferable that the belt checking cover is hinged on the brush bar cover disposed at a Iower portion of the suction brush body, for covering the brush bar and having an opening port formed therein thmugh which the brush barmay be exposed.

FIG. l is an exploded schematic perspective view showing a general upright type vacuum cleaner; and FIGS. 2 and 3 are perspective views showing a suction brush for an upright type vacuum cleaner according to the present invention.
DETAILED DESCRIPTI'ON~OF THE PREFERRED EMBODIMENT
, Hereinafter, a suction brush for an upright type vacuum cleaner according .
to a preferred embodiment of the present invention will be descn'bed in greater detail with reference to the accompanying drawings:
Referring to FIGS. 2 and 3, a suction brush for an upright type vacuum cleaner according to a preferred embodiment of the present invention comprises a suction brush body 30, a brush bar 40 disposed in the suction brush body 30, a driving force transmission belt 50 (shown in phantom in FIG: 3); capable of traveling inside the suction brush body 30, and a belt checking cover 60'disposed at-a Iower portion~of the suction brush body 30.
As shown in FIG. 1, the suction brush body 30 is rotatably connected to a lower side of a cleaner body. The lower side of the: cleaner body is provided with a motor driving chamber for providing the suction brush body 30 with a suction force, as in a conventional upright type vacuum cleaner, such as that shown in FIG. 1.
The brush bar 40 is rotatably disposed in a first mounting section 3I provided in the suction brushbody 30. The brush bar :40 brushes contaminants aff from a cleaning surface during the rotation. At a lower side of the suction brash body 30 a brush bar cover 35 for covering the brush bar 40 is removably connected. The brushbar cover 35 is provided with an opening port 35a through which the brush bar 40 is outwardly or downwardly exposed, for drawing in contaminants and air therethrough.
The driving force transmission belt 50 travels inside the suction brush body 30 to transmit the driving force to the brush bar 40. The driving force transmission belt 50 travels in a perpendicular direction with respect to the brush bar 40. For this, the suction brush body 30 is provided with a second mounting section 3~ perpendicular to the first mounting section 31, for housing the driving force transmission belt 50 therein. The second mounting section 32 communicates with the first mounting section 32 and the motor driving chamber.
Accordingly, a shaft 71 of the motor 70 (shown in phantom in FIG. 3) is mounted in the motor driving chamber and extends into the first mounting section 31. The driving force transmission belt 50 is connected to the shafr '7i extended into the second mounting section 32 and the brush bar 40, and travels between the shaft 7I and the second mounting section 32.
The second mounting section 32 is opened and closed by the belt checking cover 'Y ~ 4 to expose the driving force transmission belt 50. The belt checking cover 60 easily opens the second mounting section 32 to checks on the condition of the driving force transmission belt 50 or the contamination of the second mounting section 32 during the operation of the vacuum cleaner. One end of the belt checking cover 60 is pivotably connected to the brush bar cover 35, as shown. The other end s of the belt checking cover 60 is removably connected to and removed from the suction brush body 30 by a so-called "one touch"
latching mechanism. For this "one touch" latching mechanism, the belt checking cover 6U
has a defornaable resilient member 61 formed at the other end thereof and defining a locking hole or a locking protrusion. Inside of the second mounting section 3~ there is provided a locking section corresponding to the locking hole or the locking protrusion of the resilient member 61.
According to the construction as'described above, usually, the vacuum cleaner is operated with the second mounting section 32 being closed by the belt checking cover 60 as shown in FIG. 2. Then if the brush bar 40 does not completely or smoothly rotate, the second mounting section 32 can be opened simply by opening the belt checking cover 60 for the purpose of checking the driving force transmission belt SO Accordingly, it is possible to check for the contamination or the condition of the driving force transmission belt 50.
Unlike the conventional vacuum cleaner in which a lower portion is required to be separated for a check on the condition of the driving force transmission belt 50, the suction brush according to the present invention has an advantage since the lower portion of the suction brush is not separated for the checking operation.
Meanwhile, although this embodiment described the belt checking cover 60 pivotably connected to he brush bar cover 35, it is just by way of exart~le, and accordingly any proper variations are possible. ' For example; it is possible that the belt checking cover . 5 60 be directly connected to the uction brush.body 30.
According to the suction brush for the upright type vacuum cleaner as constructed above, by providing the suction brush body 30 with the belt checking cover 60 capable of opening and closing the driving force transmission belt SO for rotating a brush bar 40, the S condition or the contamination of the driving force transmission belt S0 is easily checked.
Accordingly, there is an advantage that the user can easily check the condition of the suction brush for proper operation.
The cleaner body 10 is divided into a dust collecting chamber 11 where a dust filter (not shown) is removably disposed and a motor driving chamber 12 where a motor for generating a suction force is disposed. The dust collecting chamber l l is opened and closed by a cover I3.
Additionally, provided in the suction brush 20 is a brush bar 21 for brushing contaminants off the surface to be cleaned, while being exposed at a lower portion of the suction brush 20: The brush bar 21 is rotated by a rotation force that is transmitted from the motor disposed in the motor driving chamber 12 via a driving force transmission belt 23 (shown in phantom).
