Abstract
A cleaning head for a surface cleaning apparatus comprises a housing having a surface contacting surface, a first inlet provided in the surface contacting surface and in communication with a first treatment stage and a second inlet spaced from the first inlet and provided in the surface contacting surface and, in use, in communication with a second treatment stage and a source of suction.
Description
- This application relates to dirt bin or dirt container for an apparatus for cleaning a surface, such as a vacuum cleaner, carpet extractor or the like. The dirt container has a first chamber for collecting larger particulate matter and a second chamber for collecting finer particulate matter. Each chamber is in communication with the surface being cleaned by a separate entrance. In one aspect of the invention, the first chamber comprises a settling chamber and the second chamber comprises a cyclone.
- Various different formats of vacuum cleaners are known in the art. These include upright vacuum cleaners, canister vacuum cleaners, stick vacuum cleaners and central vacuum systems. Typically, a vacuum cleaner uses a combination of mechanical action (e.g. a rotating brush) and suction to entrain material in a dirty air stream that enters the vacuum cleaner. One or more filtration members are provided for removing particulate matter from the dirty air stream. In the past, vacuum cleaners used filter bags to filter the dirt air. More recently, vacuum cleaners have used a plurality of cyclones or at least one cyclone with additional physical filter mechanisms downstream from the cyclone to treat the dirty air.
- If a vacuum cleaner uses more than one treatment step, then, typically, the dirty air stream is treated sequentially in each step as the dirty air passes through the vacuum cleaner. Accordingly, the surface cleaning head of the vacuum cleaner has a single dirty air inlet. An airflow path extends from the dirty air inlet through the vacuum cleaner to the cleaned air outlet of the vacuum cleaner. Accordingly, the filtration mechanisms are provided in a series of stages along the airflow path and each treatment stage must be sized to permit all of the air stream to pass therethrough.
- In accordance with one aspect of the instant invention, a surface cleaning head is provided with at least two inlets. A first inlet is associated with a brushing member and is in communication with a first treatment stage. A second inlet is spaced from the first inlet and is in communication with a second treatment stage. Accordingly, as the surface cleaning head is passed over a surface, some particulate matter enters the surface cleaning head via the first inlet and other particulate matter enters the surface cleaning head via the second inlet.
- In one embodiment, the first and second treatment stages are isolated from each other, i.e., one is not downstream from the other. Accordingly, particulate matter that enters through the first inlet will not be treated in the second treatment stage and particulate matter that enters through the second inlet will not be treated in the first treatment stage.
- Preferably, the first treatment stage receives larger and heavier particulate matter, such as that which may be swept up by a rotating brush. Such material will tend to settle out of air by gravity and, accordingly, the first treatment stage may comprise or consist of a settling chamber. Preferably, the second inlet is upstream from a source of suction and the second treatment stage receives smaller and lighter particulate matter, such as that which will be entrained in an air stream but will tend to not settle out of air by gravity. Accordingly the second treatment stage may comprise one or more of a filter, cyclone or the like. In such an embodiment, the first treatment stage may not be in airflow communication with the source of suction and, accordingly, the chamber may only have an inlet positioned to receive particulate matter conveyed thereto by mechanical brushing action and no outlet. In another embodiment, the chamber may also be in airflow communication with the source of suction. In such a case, the surface cleaning apparatus is preferably configured so that most of the air drawn by the suction source enters through the second inlet. By providing a bleed stream of air to pass through the chamber, the finer particulate matter that enters the chamber and which will tend not to settle, or which may not remain settled as the surface cleaning head is moved, may be removed from the chamber and conveyed to a further treatment stage.
- Preferably, the brushing member is a rotatably mounted brush. The chamber is positioned to receive particulate matter swept up by the brush. Preferably, the bottom of the chamber is positioned below the inlet to the chamber so that particulate matter will be retained in the chamber. For example, the chamber may be located at the end of a ramp that extends upwardly from the inlet associated with the brush to the inlet of the chamber.
- The chamber is preferably configured to permit particulate material to settle out under the influence of gravity.
- The second treatment stage preferably comprises at least one cyclone, for removing particulate matter from the air stream drawn through the second inlet. If some air is drawn through the first inlet, then the cyclone may be downstream from both the first treatment stage and the second inlet. Alternately, the cyclone may not be downstream from the first treatment stage, in which case the cyclone outlet and the outlet from the chamber may be conveyed to a further treatment stage.
- These and other advantages of the instant invention will be more fully and completely understood in accordance with the following description of the preferred embodiments of the vacuum cleaner in which:

Further, each ofsettling chamber 38 andcyclone chamber 44 are provided with a separate inlet.Inlet 42 for the lighter dirt is positioned rearward (in the normal direction of travel of surface cleaning head 12) from thefirst inlet 40. In this construction,cyclone chamber 44 is not in fluid flow communication with settlingchamber 38. Accordingly, in operation, heavier or larger particulate matter is swept up bybrush 30 and deposited in settlingchamber 38. Lighter and finer particulate matter is entrained in an air stream enteringsecond inlet 42 and is separated from the dirty air via the cyclonic action incyclone chamber 44.
