Definitions

  • This invention relates to domestic tumble dryers.
  • a tumble dryer gently tumbles wet clothes in a current of warm air after they have been spun in a washing machine. Moisture is evaporated until the clothes are dry.
  • a mechanical dryer is not weather dependent, is much quicker and easier to load, can be used during the day or night, produces fully dry or ironing dry results at the push of a button, and generally fluffs up the load.
  • An embodiment provides a domestic tumble dryer, comprising air circulating means for passing a stream of air through the load in the tumble dryer, in order to dry the load, the air circulating means being capable of communicating with a vent to the outside air so that the drying stream includes outside air for at least part of the drying cycle.
  • the drying stream includes heated inside indoor air over a first part of the drying cycle and unheated outside outdoor air over a second part of the drying cycle.
  • a tumble dryer is housed in a cabinet 1.
  • the load is loaded through a door 2 into a drum 3 which is rotated by means of a motor 4.
  • the central part 5 of the rear of the drum is perforated to allow the intake of heated air in the direction of the arrow A, which is driven into the drum by means of an impeller 6 mounted on the motor 4 which forces air through a heater 7.
  • the heated air which is passed through the load is filtered by filter 3a before being exhausted via a conduit 8 in the direction of arrow B.
  • the conduit 8 communicates with a vent 9 which passes through an external wall of a room in which the dryer is housed and communicates with the air outside.
  • the dryer could as an alternative exhaust via arrow B through a window by means of a hose.
  • the air drawn into the tumble dryer which forms the drying stream A would normally be drawn from within the room in which the dryer was housed but can also be drawn in directly from outside via vent 10, which allows fresh air to be drawn in in the direction of arrow C.
  • the clothes are dried solely using a stream of outside air which is drawn through vent 10 communicating with the outside air into the dryer where it is heated and passes through the clothes in the direction of arrow A, before being exhausted in the direction of arrow B.
  • a load produced by the dryer has a fresher smell than a load produced by a dryer using indoor air solely.
  • the second dryer has a single vent 11 extending through an exterior wall of the room in which the dryer is located.
  • heated air passes in the direction of arrow A through the load which is contained in a drum 3 rotatable by a motor (not shown) in a cabinet 1, loaded through a door 2.
  • the motor also rotates the impeller 6 as in the first embodiment and passes the air stream through heater 7 before entering the drum through a perforated region 5 on the rear wall.
  • the dryer needs a single hole through an exterior wall, which is required at the present time for current dryers which vent to the outside.
  • a valve member 12 of a valve 13 is in a first position.
  • the dryer picks up inside air from the room in which the dryer is housed (arrow D) by means of the impeller 6 which drives it into the drum 3 via the heater 7 (arrow A).
  • the moist air is exhausted through vent 11 first of all passing through filter 3a before leading back to the valve 13 (arrow E).
  • valve member 12 in a second stage of the drying operation in which the heater 7 is switched off, the valve member 12 has been moved to a second position, and impeller 6 now draws outside air through the vent 11 (arrow F) to pass through the load (arrow A) whereupon the cool dry air stream passes through the filter 3a and is exhausted to the interior of the room (arrow G) at the other side of the valve member.
  • the dryer may carry out a cooling operation following the drying one by using indoor air drawn in by impeller 6 but with the heater elements 7 switched off. Then, at the end of the normal drying operation, a special "fresh air" programme on the timer could then move the valve member 12 from the position shown in Figure 3 to the position shown in Figure 4 to allow an additional "fresh air” stage.
  • the valve member 12 may be controlled automatically by the programme control of the dryer, or it may be controlled manually.
  • vents 9 and 10 could be run parallel to each other so that the incoming fresh air (C) is preheated by the outgoing moist air (B).
  • valve 15 may be used in the embodiment of Figure 2 in place of the valve 13. With this valve, a movable tube 14 slides from the solid line position to the dotted line position to register with different holes in the valve body, while still remaining connected to the vent 11, which connects directly to a flexible bellows section 16.

Claims (3)

  1. Sèche-linge à usage domestique comprenant un moyen de circulation d'air permettant de faire passer un courant d'air à travers la charge dans le sèche-linge, afin de sécher la charge, le moyen de circulation d'air comprenant un clapet (13, 15) et étant adapté pour communiquer, lors du fonctionnement, avec un tuyau d'évacuation (11) conduisant à l'air ambiant extérieur, et pour communiquer, lors du fonctionnement, avec l'air intérieur, de sorte que dans un première position du clapet (13, 15) la vapeur de séchage (A) comprenne de l'air intérieur pour une partie du cycle de séchage, et dans une seconde position du clapet la vapeur de séchage (A) comprenne de l'air ambiant extérieur pour une partie du cycle de séchage ;
    caractérisé en ce que le clapet (13, 15) dans la première position permet à l'air humide d'être évacué (E, H) à travers le tuyau d'évacuation (11), et dans la seconde position permet à l'air ambiant extérieur d'être aspiré (F, I) à travers le même tuyau d'évacuation (11).
  2. Sèche-linge selon la revendication 1, dans lequel le tuyau d'évacuation (11) et le clapet (15) comprennent un tube mobile (14) relié à le tuyau d'évacuation et se déplaçant d'un première position vers une seconde position pour coïncider avec différents trous d'un corps de clapet pour ainsi évacuer (E, H) l'air humide chaud du sèche-linge à travers le tuyau d'évacuation (11), ou aspirer de l'air ambiant extérieur dans le sèche-linge à travers le même tuyau d'évacuation (11).
  3. Sèche-linge selon l'une quelconque des revendications précédentes dans lequel dans la seconde position du clapet (13, 15), le moyen de circulation d'air évacue (G) l'air du sèche-linge à l'intérieur d'une pièce dans laquelle le sèche-linge est situé lors de l'utilisation.
