Description
t Suction Brush for a Vacuum Cleaner The present invention relates to an
upright type vacuum cleaner, and more particularly, to a suction brush for an upright type vacuum cleaner that draws in a mixture of air and contaminants as it moves over a surface to be cleaned.
As shown in Figure 1, an upright vacuum cleaner generally comprises a suction brush 20 connected to a cleaner body 10. In use, the suction brush 20 is moved along an underlying surface to be cleaned. The cleaner body 10 is divided into a dust collecting chamber 11, in which a dust filter (not shown) is removably disposed, and a motor driving chamber 12, in which a motor for generating a suction force is disposed. The dust collecting chamber I 1 can be opened and closed using a cover 13.
In addition, within the suction brush 20 is provided a brush bar 21 arranged to brush contaminants from the surface to be cleaned using part of the bar which protrudes from a lower portion of the suction brush 20. The brush bar 21 is rotated by the motor in the motor driving chamber 12 via a driving force transmission belt 23 (shown in phantom in Figure 1).
In the above-described construction, when the motor is operated, a strong suction force is generated at the lower part of the suction brush 20. As a result of the suction force, the mixture of air and contaminants is drawn into the dust collecting chamber 11 of the cleaner body 10, from the cleaning surface.
A rotation force is transmitted from the motor to the brush bar 21 via the driving force transmission belt 23. The brush bar 21 rotates and brushes the contaminants from the cleaning surface, thereby removing contaminants from the surface by drawing them into the dust collecting chamber 11.
The drawn mixture of air and contaminants flow into a dust filter (not shown) disposed in the dust collecting chamber 11. At this point, various contaminants entrained in the
air are filtered through the dust filter, and the air is discharged through the motor driving chamber 12.
However, the above-described upright type vacuum cleaner has a disadvantage in that the driving force transmission belt 23 can be contaminated by contaminants that are inadvertently transferred from the brush bar 21. Indeed, when matter such as hair or string becomes tangled in the transmission belt 23, the driving force is not efficiently transmitted to the brush bar 21 and thus rotation of the brush bar 21 can be hindered or stopped. Also' there may be occasions when the transmission belt 23 is broken during operation. In order to check for tangling and for the condition of the transmission belt 23, the suction brush 20 has to be separated from the vacuum cleaner. Therefore, inconvenience arises since the condition of the driving force transmission belt 23 and the motor has to be checked.
According to a first aspect of the invention, there is provided a suction brush for an upright type vacuum cleaner, the brush capable of being disposed on a vacuum cleaner body and arranged to move over a surface to be cleaner in order to draw in contaminants from the surface using a suction force generated from a motor driving chamber disposed at a lower portion of the vacuum cleaner body, the suction brush comprising: a suction brush body; a brush bar rotatably disposed inside the suction brush body and arranged to brush contaminants from the surface to be cleaned; a driving force transmission belt disposed inside the suction brush body, and arranged to transmit a rotation force to the brush bar from a motor disposed in the motor driving chamber; and a belt checking cover disposed at a lower portion of the suction brush body and operable to allow the condition and contamination state of the driving force transmission belt to be checked.
According to a second aspect of the invention, there is provided a suction brush unit for an upright type vacuum cleaner, the unit comprising: a housing having a belt cavity defined therein which is accessible from a lower surface of the housing; a brush bar rotatably disposed within the housing, part of the brush bar protruding from the lower surface of the housing; a transmission belt located at least partly within the belt cavity
and arranged to transmit a driving force from a motor to the brush bar thereby to cause the brush bar to rotate; and an inspection cover movable from a position in which at least part of the belt cavity is covered, and a position in which the belt cavity is uncovered so as to allow access to the transmission belt from the lower surface of the housing. In the preferred embodiment, a suction brush for an upright type vacuum cleaner is described having improved construction which allows easy checking/inspection of the condition of the transmission belt of the suction brush.
This is accomplished by providing a suction brush for an upright type vacuum cleaner in which the suction brush is rotatably attached to a cleaner body so that it can be moved along a surface to be cleaned. The brush can draw in contaminants from the surface using a suction force generated from a motor driving chamber arranged at a lower portion of the cleaner body. In the preferred case, the brush includes 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 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 enable checking for contamination and the condition of the driving force transmission belt.
It is preferable that the belt checking cover is hinged to the brush bar cover at a lower portion of the suction brush body, the brush bar cover covering the brush bar and having an opening port formed therein through which the brush bar is exposed.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is an exploded perspective view of a conventional upright type vacuum cleaner; and
Figures 2 and 3 are perspective views showing the underside of a suction brush for an upright type vacuum cleaner according to the present invention.
Referring to Figures 2 and 3, a suction brush for an upright type vacuum cleaner comprises a suction brush body 30, a brush bar 40 disposed in the suction brush body 30, a transmission belt 50 (shown in phantom in Figure 3), which is arranged to rotate inside the suction brush body 30, and a belt checking cover 60 disposed in a lower region of the suction brush body 30.
As in the vacuum cleaner shown in Figure l, the suction brush body 30 shown in Figures 2 and 3 is pivotally connected to a lower side of a cleaner body. The lower side of the cleaner body would be provided with a motor driving chamber for generating a suction force at the suction brush body 30.
The brush bar 40 is rotatably disposed in a first mounting section 31 of the suction brush body 30. In use, the brush bar 40 brushes contaminants from an underlying cleaning surface during rotation. At the lower side of the suction brush body 30, a brush bar cover 35 is removably connected. The brush bar cover 35 is provided with opening ports 35a through which the brush bar 40 outwardly and downwardly protrudes. Contaminants and air can be drawn through the opening ports 35a.
The transmission belt 50 travels inside the suction brush body 30 so as to transmit the driving force of the motor to the brush bar 40. The transmission belt 50 travels in a generally perpendicularly with respect to the longitudinally axis of the brush bar 40.
The suction brush body 30 is provided with a second mounting section 32, disposed generally perpendicularly to the first mounting section 31, within which the driving force transmission belt SO is housed. The first and second mounting sections 31, 32 communicate with each other to define an L shaped cavity which itself communicates with the motor driving chamber. A shaft 71 of the motor 70 (shown in phantom in Figure 3) is mounted in the motor driving chamber and extends into the first mounting section 31. The transmission belt 50 is connected to the motor shaft 71 and extends along the second mounting section 32 and is connected to the brush bar 40. The
transmission belt 50 Ravels between the shaft 71 and the brush bar 40, inside the second mounting section 32.
The second mounting section 32 is able to be opened and closed by means of the belt checking cover 60 thereby to expose, and allow access to, the transmission belt 50.
Specifically, the belt checking cover 60 can be easily opened to allow checking of the condition of the transmission belt 50, or to allow inspection of the second mounting section 32 during the operation of the vacuum cleaner to see if contaminants are present. One end of the belt checking cover 60 is pivotally connected to the brush bar cover 35, as shown in Figure 3. The free end of the belt checking cover 60 is removably connected to part of the suction brush body 30 by a so-called "one touch" latch mechanism. This "one touch" latching mechanism of the belt checking cover 60 comprises a deformable resilient member 61 formed at the free end thereof defining either a locking hole or a locking protrusion. Inside the second mounting section 32, there is provided a locking section corresponding to the locking hole protrusion of the resilient member 61 so as to enable engagement therewith.
According to the construction described above, the vacuum cleaner is usually operated with the second mounting section 32 closed by means of the belt checking cover 60 being in the position shown in Figure 2. If the brush bar 40 does not completely or smoothly rotate, the second mounting section 32 can be opened by simply opening the belt checking cover 60 so that the driving force transmission belt 50 can be inspected.
Accordingly, it is possible to check the condition of the transmission belt 50 to see whether the belt has become tangled or contaminated. Unlike the conventional vacuum cleaner, in which a lower portion has to be separated in order to check the condition of the transmission belt 50, the suction brush described herein has an advantage since the lower portion of the suction brush does not have to be separated in order for a checking operation to be performed.
Although the embodiment described above uses a belt checking cover 60 which is pivotally connected to the brush bar cover 35, variations are possible. For example, it is
possible for the belt checking cover 60 to be connected directly to the suction brush body 30.
By providing the suction brush body 30 with the belt checking cover 60 capable of both enabling and preventing access to the transmission belt 50 for rotating a brush bar 40, the condition and/or contamination state of the transmission belt 50 can be easily checked. Accordingly, there is the advantage that a user can easily check the condition of the suction brush to ensure proper operation.
