Definitions
- the present invention relates to an apparatus for cleaning of textile objects by a densified liquid state treatment gas, such as liquid carbon dioxide, in a treatment chamber in which a high pressure prevails during the treatment process in order for the treatment gas to remain in liquid phase at essentially ambient temperature, said treatment chamber, at one side gable thereof, being closable by means of a door and encloses a rotatably mounted wash drum supporting the textile objects to be cleaned, said wash drum being rotated by a driving device comprising an electric motor and possibly a transmission.
- a densified liquid state treatment gas such as liquid carbon dioxide
- Another object of the invention is to remedy the drawbacks associated with the use of jets of a treatment liquid for the cleaning of the laundry and for stirring of the same and/or rotation of the wash drum. Another object of the invention is to eliminate the need for couplings between the wash drum in the treatment chamber and a driving device situated outside of the treatment chamber. A further object of the invention is to facilitate service on a driving device provided for the rotation of the drum.
- such belt is usually chosen to be made from a material not penetrated and broken down by the carbon dioxide.
- a material is PPSE, a TEFLONTM type material.
- a belt has been chosen made from polycloroprene marketed under the name " Poly-V-profile" by the German company OPTIBELT.
- Fig. 1 schematically shows a longitudinal section along a treatment chamber closable by a door and having a wash drum rotatably provided and driven by a driving device built-in into said treatment chamber; and Figs. 2 and 3, also schematically, show a sledge which supports the wash drum and the driving device, where Fig. 2 shows a section through the treatment chamber at the side opposite to the door and Fig. 3 is a section along the line III-III in Fig. 2.
- the invention relates to an apparatus for cleaning of textile objects by a densified liquid state treatment gas, such as liquified carbon dioxide, in a treatment chamber.
- a densified liquid state treatment gas such as liquified carbon dioxide
- the apparatus hereinafter referred to as a washing machine, in addition to the treatment chamber and the wash drum rotatably disposed therein, comprises a plurality of further components and a control device for the control of the washing machine.
- a view of the design of such washing machine can be obtained from the patent publication US-A-5, 267 , 455, referred to above. The description given below will be restricted to the treatment chamber and the arrangement therein.
- a treatment chamber 10 is shown in the form of a drum-shaped outer container in which a wash drum 12 is rotatably disposed.
- the treatment chamber 10 is designed to resist high pressures and is closable by means of a door 14 together with suitable locking means, not shown.
- the wash drum 12 is provided with a shaft 16 journalled in bearings 18, 20 provided in a bearing housing 22.
- a pulley 24 is attached to the free end of the shaft 16 and is intended, via a transmission belt 26, to be connected to a corresponding pulley 28 provided on the shaft of an electric drive motor 30.
- the drive motor is excentrically disposed with respect to the shaft 16 of the wash drum at as high level as possible in the treament chamber 10.
- the spaces not occupied by the shaft support and the driving device for the wash drum are filled with a suitable material, such as a plastics material or aluminium, as schematically indicated by 32 in Fig. 1.
- a suitable material such as a plastics material or aluminium, as schematically indicated by 32 in Fig. 1.
- the power supply to the electric motor 30 takes place via a pressureproof coupling device 34 to which connects an outer lead 36.
- a corresponding inner lead 38 connects to the motor 30.
- pressureproof coupling devices are available in the market where a suitable design can be chosen.
- the wash drum 12 is rotated by the drive motor 30 via the transmission belt 24 in the same way as in washing machines intended for water wash.
- the drive motor 30 excentrical with respect to the drum shaft 16
- the motor will occupy essentially the same space as the support 18, 20 for the drum shaft 16 resulting in a very compact design of the driving device.
- no drive components will be required which call for space outside of the treatment chamber 10.
- the treatment chamber 10 comprises a sledge device 40 provided to movably support the wash drum with the shaft support and the driving device, the sledge device 40 being adapted to alternatively take a first position in the treatment chamber 10 or a second position outside the same.
- the sledge device is formed mainly by the bearing housing 22 provided for the bearings 18, 20, said bearing housing (22) having wheels 42 suitably distributed along the inner periphery of the treatment chamber 10.
- the wheels 42 are rolling on and steered by longitudinal races 44 fixedly mounted to said inner periphery of the treatment chamber 10.
- the sledge device 40 On repair and maintenance of the components of the sledge device 40 said device is manually moved from its position in the treatment chamber to a service position adjacent to the loading opening of the treatment chamber. In case of more extensive service the sledge device 40 and components supported thereon can be transferred to a handling carriage, or the like, by means of which it can be transported to a suitable workshop. Of course, the sledge device can be moved from its normal position in the treratment chamber to the service position by means of motor operated means of a suitable design.
- the invention has been described in the form of an embodiment of no-limiting nature. Accordingly, a plurality of modifications can be made within the scope given by the appendant claims.
- the wheels of the sledge device can be replaced by gliding cushions or the like.
