Abstract

A vacuum cleaner installation has a unit with an outer housing installed within the thickness of an outside wall of a room. The housing contains a blower, a bag for waste material and a hose. The blower is connected to draw waste material along the hose and into the bag, the exhaust air venting externally of the room through a grille on the outside wall.

Description

    BACKGROUND OF THE INVENTION
  • This invention relates to installations and arrangements [0001]
  • The invention is more particularly concerned with vacuum cleaner installations and arrangements [0002]
  • Conventional vacuum cleaners are portable equipment including a blower, which draws dust into a container for disposal. The container may be a porous bag that acts as a filter so that the waste material remains in the bag and air passes through the wall of the bag and is exhausted into the room. Alternatively, the container may be a non-porous canister, the equipment including a separate filter to remove dust particles from air exhausted into the room. These forms of cleaner have several disadvantages. First, because the waste air is exhausted into the room, special precautions must be taken to ensure that small particles of dust, pollen and allergens are removed from the exhaust. This may be done by means of a HEPA filter but these are relatively expensive items that have to be replaced regularly by the user, adding to the cost and inconvenience of using the cleaner. Also, the presence of the filter provides a restriction to flow of air through the cleaner and, therefore, reduces its efficiency, especially as the filter becomes clogged during use. Another disadvantage with these cleaners is that the temperature of the outlet air is relatively high, which can lead to undesirable raising of the room temperature during use. A further problem inherent in these portable vacuum cleaners is that they are relatively heavy and cumbersome, which is a particular problem where the cleaner has to be moved between different floors in a building or where it has to be used by someone who is infirm or disabled. [0003]
  • An alternative vacuum cleaner system, which is less common in the UK, is the central vacuum cleaner system where the pump/blower and dust container are fixed installations, usually in a basement Qr garage, and conduits connect the pump to various inlets at different locations throughout the building. The user connects a hose to the closest inlet and the waste material is sucked through the hose to the pump and container via the conduits. This arrangement has some advantages over the portable cleaners in that the user only has to carry the hose and the suction air exhausts into the room in which the pump is installed, not into the room being cleaned. These systems, however, have several problems. They are relatively expensive and cannot be installed in all buildings. Also, the conduits can be prone to blockage. [0004]
    • BRIEF SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide an alternative vacuum cleaner installation and arrangement. [0005]
  • According to one aspect of the present invention there is provided a vacuum cleaner installation including a room and a vacuum cleaner arrangement, the vacuum cleaner arrangement includes a blower and a receptacle for waste material installed in the room, and the vacuum cleaner arrangement having an inlet opening into the room and an air exhaust outlet venting externally of the room. [0006]
  • The vacuum cleaner arrangement preferably is mounted within the thickness of the wall of the room and may have a hose that is retractable into a housing of the arrangement. [0007]
  • According to another aspect of the present invention there is provided a vacuum cleaner arrangement for an installation according to the above one aspect of the present invention. [0008]
  • A vacuum cleaner installation including a vacuum cleaner arrangement according to the present invention, will now be described, by way of example, with reference to the accompanying drawings.[0009]
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a plan view of the installation in a building; [0010]
  • FIG. 2 is a perspective view of the vacuum cleaner arrangement in more detail; and [0011]
  • FIG. 3 is a sectional side elevation view of the arrangement.[0012]
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The installation comprises a vacuum cleaner unit or [0013] arrangement 1 installed in a fixed position within the outside wall 2 of a room 3 in a building 4.
  • The [0014] vacuum cleaner unit 1 includes an outer casing 10 of generally rectangular section with a rear wall 11, a front wall 12, two side walls 13 and 14, a top 15 and a base 16. The front wall 12 is hinged about a vertical axis to provide an opening door enabling access to the interior of the unit and supporting various tools 18. Within the casing 10, the unit 1 has a pump or blower 20 with an inlet 21 and an outlet 22. The inlet 21 is connected via a coarse filter 23 to a rigid housing 24 containing a disposable, porous bag 25 the neck 26 of which is secured about one end of tubing 27. The other end of the tubing 27 extends to a rotatable coupling 28 to which is connected one end of a flexible hose 29. The outlet 22 of the pump opens through the rear wall 11 externally of the outside wall 2 and may be terminated by a grille 30, which may include a one-way flap valve of conventional kind. . The unit 1 is fitted in a hole 100 cut in the outside wall 2 and is contained within the thickness of the wall, which is typically about 275 mm. If the unit is deeper than the wall it may project externally or internally. Alternatively, the unit could be mounted on the inside surface of the wall.
  • The [0015] hose 29 is wound on a sprung reel (not shown) behind the front wall 12 and its free end projects through an opening 40 in the front wall so that the hose can be pulled out away from the unit 1 for use. The length of the hose 29 is selected such that it is sufficient to reach the furthest comer of the room 3 and may be sufficient to enable adjacent rooms 5 and 6 also to be cleaned.
  • In operation, the [0016] pump 20 is turned on, either by actuation of a manual switch or in response to pulling out the hose 29. This applies suction to the housing 24 containing the bag 25 so that this suction is also applied via the tubing 27 to the hose 29. Air, dust and other waste material, therefore, flows along the hose 29, along the tubing 27 and into the bag 25. Dust and larger particles are trapped in the bag 25 whereas air and small particles pass through the wall of the bag and flow through the pump 20 via the filter 23. This waste air and small particles are then exhausted via the outlet 22 outside the room 3. When the bag 25 is full, it is disposed of or emptied and replaced. The filter 23 does not need replacing regularly since it is only required to prevent passage of larger particles to the pump 20.
  • This installation has the advantage that all the waste air is exhausted externally of the room so there is no risk of even the smallest of particles, pollen or allergens being recirculated within the room, as with conventional vacuum cleaners. This makes the installation particularly suitable for use by people with asthma or allergies. There is also no need for expensive high efficiency filters of the kind that are used in some conventional vacuum cleaners. By venting the warm outlet gas outside the room, there is less unwanted heating caused by use of the equipment. Furthermore, the user only has to move the hose, so the equipment is easier to use especially by infirm or disabled people. The installation of the equipment can be carried out easily without the need to make extensive modifications to the building, as with central vacuum cleaner installations. Because the unit can be contained within the thickness of the wall, it takes up little or no space in the room, thereby reducing the need for storage space. This kind of installation is particularly suitable for use in bedsits, hotels or in buildings with several floors where there would be an installation on each floor. [0017]
  • It will be appreciated that the installation could be modified in various ways. For example, the hose could include an electrical wire to supply power to a beater head at the end of the hose. The hose need not be on a reel but could be stored separately and connected to a coupling on the unit when needed. [0018]
