Definitions

  • This invention relates to a machine for washing and drying domestic laundry, comprising a cabinet containing a stationary tank for holding washing liquor, a detergent distributor located above the tank, a perforated drum within the tank for holding laundry to be washed and subsequently dried in the drum, the drum being rotatable inside the tank about a horizontal axis, a fan and a heater for generating a stream of hot air for drying the laundry, and ducts for conducting the hot air from the heater into the drum and for conducting away from the tank the air which passes from the drum into the space between the drum and the tank via the perforations in the drum.
  • This air may be exhausted to the exterior of the cabinet or it may be cooled to remove moisture from it by condensation and then be returned to the fan for recirculation in the machine.
  • washing and drying machine is often referred to as a "washer/dryer” and ideally combines the benefits of both a washing machine and a tumble dryer in a single unit no larger than an ordinary washing-only machine.
  • This space-saving benefit is particularly significant in modern times when domestic appliances must be designed to fit into small kitchens and must also conform to standardised kitchen unit dimensions.
  • a machine for washing and drying domestic laundry comprising a cabinet containing a stationary tank for holding washing liquor, a detergent distributor located above the tank, a perforated drum within the tank for holding laundry to be washed and subsequently dried in the drum, the drum being rotatable inside the tank about a horizontal axis, a fan and a heater for generating a stream of hot air for drying the laundry, and ducts for conducting the hot air from the heater into the drum and for conducting away from the tank the air which passes from the drum into the space between the drum and the tank via the perforations in the drum, characterised in that the fan is a high-speed fan capable of developing at its outlet an air pressure within the range of 4 cm to 8 cm of water, in that the fan, a motor for driving the fan and the heater are all housed in a box which is mounted on the outside of the back of the cabinet, and in that the duct which conducts the hot air from the heater into the drum is made of an elastomeric material and extends across
  • the heater may have a small heater chamber and the fan may also be small. Consequently, due to the small size of the fan and the heater chamber, the box in which the fan and heater are housed on the back of the cabinet adds very little to the depth of the machine. Also air ducts of small cross-sectional area may be used which can readily be accommodated in the limited space available between the internal components of the machine.
  • the high pressure of the air system also allows the air, at high velocity, to leave the tank through the relatively small hole which is normally provided in the bottom of the tank for the removal of the dirty washing liquor and rinsing water.
  • An embodiment of the invention in which the front walls of the cabinet, the tank and the drum are formed with aligned openings through which laundry can be loaded into the drum, and a flexible annular seal extends between the front walls of the cabinet and the tank and is fixed to these walls around the openings therein, is characterised in that the hot-air duct is connected at its discharge end to an aperture in the wall of the seal so as to discharge into the drum through the aperture and through the openings in the front walls of the tank and the drum.
  • a discharge nozzle is preferably provided at the discharge end of the hot-air duct to direct the hot air stream from the duct into the drum, the nozzle having a discharge aperture which faces towards the opening in the front wall of the drum.
  • a simple method of connecting the hot-air duct to the aperture in the seal is provided in an embodiment of the invention which is characterised in that the portion of the hot-air duct which extends down the front of the tank also has a flattened shape with an elongate cross-section, and in that the aperture in the seal has an elongate shape corresponding to that of the cross-section of the hot-air duct at the discharge end thereof and extends in the circumferential direction of the seal end is surrounded by a wall which projects from the outer side of the seal and over which the discharge end of the duct fits.
  • One embodiment of the invention is characterised in that the wall which surrounds the aperture in the seal is supported internally by a rigid sleeve which has an elongate cross-section corresponding to the shape of the aperture in the seal and which also forms said discharge nozzle, the sleeve having a wall portion which projects from the inner side of the seal in a direction towards the opening in the front wall of the drum to form the discharge aperture of the nozzle.
  • washer/dryers which. comprise a condenser for removing moisture from the air used in the drying operation so that this air can be recirculated in the machine, the moist air being passed over cooling water in the condenser to effect the condensation
  • the duct through which the moist air is brought to the condenser is commonly employed to carry away the condensate and the used cooling water.
  • the air duct cannot be used satisfactorily for this purpose since, due to its hith velocity, the air flow in the duct will tend to impede the flow of water down the duct and even to drag water back into the condenser.
  • An embodiment of the invention which comprises a condenser for removing moisture from the air conducted away from the tank so that this air can be recirculated in the machine, the moist air being passed over cooling water in the condenser to effect the condensation, and ducts being provided for conducting the air from the tank to the condenser and from the condenser to the inlet of the fan, is characterised in that the condenser comprises upper and lower elongate chambers extending substantially horizontally one above the other and communicating with one another at one end, the lower chamber having at or adjacent its other end an inlet for the moist air and the upper chamber having an outlet through which air can leave the condenser, and the condenser further having an inlet through which cooling water can be fed to the lower chamber and an outlet in the bottom of the lower chamber through which cooling water and condensate can leave this chamber, the latter outlet being surrounded by a wall which projects upwardly from the bottom of the lower chamber and which acts as a weir to determine a constant level of cooling water in
  • the condenser comprises a vessel having the form of a U lying on its side with one limb directly above the other, the upper limb constituting the upper chamber of the condenser and the lower limb constituting the lower chamber and the connection between the limbs constituting a passage through which the chambers communicate with one another at said one end.
  • the condenser can be manufactured cheaply as a plastics moulding, preferably a blow moulding, to minimise the number of joints and keep the tool cost low.
  • a simple stiffening of the moulding can be obtained by forming a rigid web between two parts of the moulding which form the upper and lower chambers of the condenser vessel.
  • a simple means of forming the wall around the outlet in the bottom of the lower chamber is provided in an embodiment of the invention which is characterised in that a pipe is connected to the outlet in the bottom of the lower chamber to conduct cooling water and condensate away from this chamber, and an end portion of said pipe projects upwardly into the lower chamber to form said wall.
  • the washing and drying machine shown diagrammatically in Figures 1 and 2 comprises a stationary tank 1 of cylindrical form for holding washing liquor and within the tank a rotatable perforated drum 2 for holding the laundry to be washed and dried.
  • the tank 1 is suspended in a cabinet, of which the front wall is shown at 3 in Figure 1.
  • the tank is arranged with its axis disposed -horizontally, and the drum is rotatably supported in the tank coaxially therewith by a shaft 4 which projects from the rear end wall 5 of the drum and is journalled in a bearing (not shown) in the rear end wall 6 of the tank.
  • the shaft 4 receives drive from an electric motor by which the drum 2 can be rotated at low speed in alternate directions during the washing and tumble-drying operations and at high speed in one direction only during the spinning operation.
  • the motor is not shown in Figures 1 and 2 but Figure 3 shows a motor 7 which drives the drum of the machine shown in that figure through a belt 8 and a pulley 9 keyed on the shaft 4 of the drum.
  • the drum 2 has perforations 10 (Figure 1) in its cylindrical wall 11 and a large circular central opening 12 in its front end wall 13 through which the laundry can be loaded into the drum.
  • the tank 1 has a similar opening 14 in its front end wall 15 and a corresponding opening is provided in the front wall 3 of the cabinet, the three openings being coaxial with one another.
  • a flexible annular seal 17, for example, a rubber bellows seal, is fixed to the front end wall 15 of the tank 1 around the opening 14 therein and to the front wall 3 of the cabinet around the corresponding opening in this wall.
  • a hinged porthole door 18 is provided on the front wall of the cabinet, the door being arranged to seat in a water- and air-tight manner on a rim of the seal 17 at thel front edge of the seal, and the construction of this seal and the door 18 being such as to leave an annular space 19 between the seal 17 and a transparent portion 20 of the door which has a frusto- conical shape and protrudes into the openings 14 and 12 in the front of the tank 1 and the drum 2.
  • an outlet 21 through which the dirty washing liquor and rinsing water is removed from the tank by a pump 22.
  • the water expelled from the laundry during the spinning operation is also pumped from the tank through the outlet 21.
  • a pipe 23 leads away from this outlet and has a branch 24 which is connected to the inlet of the pump 22.
  • a drainage pipe 25 is connected to the outlet of the pump.
  • the laundry is tumble-dried in the drum 2 by passing a stream of hot air over the laundry while the drum is rotated at low speed in alternate directions.
  • the stream of hot air is produced by a high-speed fan 26 and an electric heater 27.
  • Hot air from the heater flows into the drum 2 through a duct 28 which passes over the top of the tank 1 and down the front of the tank to discharge into the interior of the drum 2 through an aperture 29 in the wall of the bellows seal 17, the space 19 between the seal 17 and the protruding portion 20 of the door 18, and the openings 14 and 12 in the front walls of the tank and the drum.
  • the hot air passes over the laundry in the drum 2 to extract moisture therefrom and then flows through the perforations 10 in the cylindrical wall 11 of the drum into the space between this wall and the surrounding wall of the tank 1.
  • the moist air leaves this space via the outlet 21 in the bottom of the tank and the pipe 23, which serves as a duct for conducting the moist air to a condenser 30.
  • the pipe 23 can be arranged to discharge the moist air to atmosphere externally of the machine, preferably through a lint filter and if desired through an extensible hose.
  • the condenser 30 comprises a container 31 which is divided internally into upper and lower chambers 32 and 33 respectively by a horizontal partition 34 which ends some distance from one wall of the container to leave an opening 35 through which the chambers communicate with one another.
  • the pipe 23 opens into the lower chamber 33 through the opposite wall of the container 31 so that the moist air flowing from the pipe 23 is constrained to flow over the surface of a quantity of cooling water 36 in the bottom of the container 31.
  • the water vapour in the air is condensed by this cooling water and precipitated from the air stream, which then flows through the opening 35 into the upper chamber 32 of the container, whence it is conducted by a duct 37 to the inlet of the fan 26.
  • the container 31 has a large volume in order to reduce the velocity of the air flow over the cooling water 36.
  • This water is fed into the container during the drying operation through a valve-controlled inlet pipe 38 and leaves the container through an outlet pipe 39.
  • One end of this pipe projects up into the lower chamber 33 through the bottom of the container; the other end is connected to the branch pipe 24 which connects the pipe 23 to the pump 22.
  • the depth of the cooling water in the chamber 33 is determined by the height to which the end of the pipe 39 projects into the chamber.
  • the container should, of course, be mounted well above the level to which the tank 1 is filled with water for the washing operation in order to avoid flooding the container.
  • FIGs 3 and 4 show the whole of the cabinet of the machine with the exception of the back panel, which has been removed so that the tank 1 and the drive 8, 9 from the motor 7 to the shaft 4 of the drum can be seen.
  • Figures 3 and 4 also show schematically a box 40 in which the fan 26 and heater 27 are housed and which is attached by screws or bolts (not shown) to the rear of the cabinet.
  • the rear wall of the box 40 in Figure 3 and a side wall in Figure 4 have been broken away to show the parts which are housed in the box.
  • these parts include a valve 41 for controlling the water feed to the condenser 30 through the pipe 38 and an electric motor 42 for driving the fan, the drive being transmitted through a belt 43 and pulleys 44 and 45 on the shaft of the fan impeller and the motor shaft respectively.
  • the condenser 30 is mounted on the back of the machine directly beneath the box 40, the water pipe 38 and air duct 37 extending through holes in the bottom of the box.
  • the cabinet has a specially shaped back panel to cover the condenser, which panel is represented by dot-dash lines 46 in Figure 4.
  • the fan 26 is driven at very high speed, for example, 7,000 r.p.m., in order to deliver air at high pressure and velocity. This allows a small fan and a heater with a small heater chamber to be used so that the dimensions of the box 40 can be kept to a minimum.
  • the air pressure at the fan outlet may be within the range 4 cm to 8 cm of water. With a high air pressure the air ducts may have a small cross-sectional area.
  • a good clearance is needed between the detergent drawer and the top of the tank 1 to allow for the amplitude of vibration of the resiliently suspended tank when the speed of the drum passes through the resonant frequency at the beginning of the spinning operation, and this clearance is utilised to accommodate the portion 49 of the hot-air duct 28 which extends across the top of the tank 1.
  • This portion and the portion 50 which extends down the front of the tank have a flattened shape with an elongate cross-section, the two flat major walls of the portion 49 being stiffened in the lateral direction by ribs 51.
  • the duct has a corrugated neck portion 52 of circular cross-section which is connected to an outlet duct 53 from the heater 27, the inlet of which is connected to the outlet of the fan 26 at 54.
  • the duct 28 has a portion 55 in which the cross-section of the duct gradually changes from a circular to an elongate shape.
  • the duct 28 is connected to the aperture 29 in the wall of the bellows seal 17 which extends between the front end wall 15 of the tank 1 and the front wall 3 of the cabinet.
  • this aperture is of elongate shape to match the cross-section of the portion 50 of the duct 28 and extends in the circumferential direction of the seal 17.
  • the aperture 29 is surrounded by an upstanding wall 56 which projects from the outer side of the seal 17 and over which fits the end of the duct portion 50.
  • the wall 56 is supported internally by a rigid sleeve 57 which is made of a plastics material and which has an elongate cross-section corresponding to the shape of the aperture 29.
  • the sleeve 57 is formed with outwardly directed flanges 58 which engage over the edges of the wall 56 to secure the sleeve in the aperture 29, and a stiffening web 59 is formed across the middle of the sleeve.
  • the sleeve 57 also forms a discharge nozzle for the duct 28, for which purpose the sleeve has a wall portion 60 which projects from the inner side of the seal 17 and curves round in a rearward direction to form a rearwardly facing discharge aperture 61 which directs the hot air stream from the duct 28 towards the central opening 12 (Figure 1) in the front wall of the drum 2. Due to this and to the high velocity of the air stream, very little hot air escapes into the gap between the front walls of the tank and the drum and by-passes the interior of the drum. To prevent small items of laundry entering this gap, an annular rim (not shown) is provided on the seal 17.
  • the duct 28 is made of a heat-resistant elastomeric material, for example, silicone rubber, which allows it to be routed through the narrow space between the detergent dispenser 48 and the tank 1. Shocks caused by contact between the duct and the tank as the latter vibrates during acceleration of the drum to its spin speed are absorbed by deformation of the flexible walls of the duct.
  • the elastomeric material and flattened shape of the duct 28 allow the duct to expand under the pressure of the air when the fan comes into operation and to collapse when the fan stops.
  • thermostats are provided to control the drying temperatures, and the drying cycle is controlled by an adjustable timer (not shown).
  • the condenser 30 comprises a vessel 61 having the form of a U lying on its side with one limb directly above the other.
  • the upper limb constitutes an elongate upper chamber 32 of the vessel and the lower limb an elongate lower chamber 33, the two chambers extending substantially horizontally.
  • the connection between the two limbs constitutes a passage 62 through which the chambers communicate with one another at one end.
  • Adjacent its other end, in one side, the lower chamber 33 has an inlet 63 for the moist air, to which inlet the pipe 23 is connected.
  • an outlet 64 through which air can leave the vessel 61. This outlet is connected to the duct 37 leading to the inlet of the fan 26. Also in the top of the upper chamber 32, directly above the passage 62, is an inlet 65 for cooling water, to which inlet a valve-controlled feed pipe 38 is connected. During the tumble-drying operation, cold water from the household supply is fed continuously to the lower chamber 33 via the pipe 38, which extends down through the passage 62 to a point just above the bottom of the lower chamber.
  • the upper end of the pipe 39 extends into the lower chamber 33 for a short distance to form a wall 67 projecting upwardly from the bottom of the chamber 33 around the outlet 66.
  • this wall acts as a weir to determine a constant level of cooling water 68 in the lower chamber.
  • the moist air conducted into the chamber 33 by the pipe 23 flows over the surface of this water, and the water vapour in the air is condensed thereby and precipitated from the air stream.
  • the air flow over the water outlet 66 tends to pick up a part of the water, creating droplets above the outlet and so assisting the action of the condenser.
  • From the lower chamber 33 the air flows through the passage 62 into the upper chamber 32 and thence through the outlet 64 into the inlet duct 37 of the fan 26 for recirculation in the machine.
  • drops of water picked up by the air flow over the cooling water in the lower chamber are deposited on the walls of the upper chamber before the air accelerates into the fan inlet duct 37. These drops of water run down to the bottom of the upper chamber and thence back into the lower chamber, the bottom wall of the upper chamber sloping downwardly from the side walls to facilitate this, as can be seen in Figure 14.
  • the chambers 32 and 33 have a substantially larger cross-sectional area than the pipe 23 in order to reduce the velocity of the moist air entering the condenser and flowing over the cooling water 68.
  • the condenser vessel 61 can be manufactured cheaply as a plastics moulding, preferably a blow moulding in, for example, polypropylene, so as to have the minimum number of joints and to keep the tool cost low.
  • a rigid web 69 is formed between the two parts which constitute the upper and lower chambers of the condenser vessel.
