Abstract

A clothes-dryer includes accessories such as a hair-dryer, hand-dryer and space heater, as well as a ventilation device for venting the room in which the dryer is disposed of undesirable air. The dryer includes an intake channel and a discharge channel which together with the basket of the dryer form a drying circuit along which a forced hot air supply flows to dry laundry contained in the basket during the normal operation of the dryer. A selection control device is provided to establish various modes of operation of the dryer in which the accessories are operated with the air supply which is normally produced when the dryer is used to dry clothes contained in the basket.

Claims

1. A clothes dryer comprising:

a basket for accommodating a load of clothes to be dried;

an intake channel in communication with the interior of said basket and with the exterior of the dryer, said intake channel defining a path along which air from the exterior of the dryer can pass to the interior of the basket to dry clothes therein;

heater means in operative association with said intake channel for heating air drawn into said intake channel from the exterior of the dryer;

a discharge channel communicating with the interior of said basket and with the exterior of the dryer, said discharge channel defining a path along which air can be vented from the interior of said basket to the exterior of the dryer, whereby said intake and said discharge channels constitute a drying circuit with the interior of said basket;

fan means in operative association with said drying circuit for drawing air from the exterior of the dryer into said intake channel;

at least one hot air utility opening open to the exterior of the drier;

a hot-air utility conduit communicating with said hot-air utility opening, and with said drying circuit at a location downstream of said heating means with respect to the direction in which air will be induced to flow through the drying circuit by said fan means; and

selection control means for selectively opening said at least one hot-air utility opening to said drying circuit while closing said discharge channel, and closing said at least one hot-air utility opening to said drying circuit while opening said discharge channel.

2. A clothes dryer as claimed in claim 1, wherein said selection control means is operatively connected to said fan means and to said heater means to control the operation thereof independently of one another, said selection control means is operable to place the dryer in an aspiration mode in which said hot-air utility opening is closed to said drying circuit, said discharge channel is open, and said fan means is operated while said heater means is not operated, and said selection control means includes a switch on the dryer which is manually operable to establish said aspiration mode.

3. A clothes dryer as claimed in claim 1, wherein said selection control means includes a deflector disposed at said location at which the hot-air utility conduit communicates with said drying circuit, said deflector being movable between a first position at which said deflector blocks the flow of air through said drying circuit while opening said hot-air utility conduit to said drying circuit and a second position at which the deflector closes said hot-air utility conduit to said drying circuit.

4. A clothes dryer as claimed in claim 1, wherein the dryer has a grill mounted thereto and defining said hot-air utility opening, said selection control means is operatively connected to said fan means and to said heater means so as to control the operation thereof, said selection control means is operable to place the dryer in a space-heater mode in which the hot-air utility opening defined by said grill is open to said drying circuit, said discharge channel is closed, and said fan means and said heater means are operated, and said selection control means includes a switch on the dryer which is manually operable to establish said space-heater mode

5. A clothes dryer as claimed in claim 4, wherein said selection control means includes a thermostat, and said fan means and said heater means are operated in said space-heater mode under the control of said thermostat.

6. A clothes dryer as claimed in claim 4, wherein said grill is located on the front of the dryer.

7. A clothes dryer as claimed in claim 1, wherein the dryer has a nozzle mounted thereto and defining said hot-air utility opening at an end thereof, said selection control means is operable to place the dryer in a hand-dryer mode in which said nozzle is open to said drying circuit, said discharge channel is closed, and said fan means and said heater means are operated, and said selection control means includes a switch on the dryer which is manually operable to establish said hand-dryer mode.

8. A clothes dryer as claimed in claim 1, wherein the dryer includes a flexible air-hose, said air hose defining said hot-air utility opening at one end thereof and connected to said hot-air utility conduit at the other end thereof, said selection control means is operable to place the dryer in a hair-dryer mode in which said flexible air-hose is open to said drying circuit, said discharge channel is closed, and said fan means and said heater means are operated, and said selection control means includes a switch on the dryer which is manually operable to establish said hair-dryer mode.

9. A clothes dryer comprising:

a basket for accommodating a load of clothes to be dried;

an intake channel in communication with the interior of said basket and with the exterior of the dryer, said intake channel defining a path along which air from the exterior of the dryer can pass to the interior of the basket to dry clothes therein;

heater means in operative association with said intake channel for heating air drawn into said intake channel from the exterior of the dryer;

a discharge channel communicating with the interior of said basket and with the exterior of the dryer, said discharge channel defining a path along which air can be vented from the interior of said basket to the exterior of the dryer, whereby said intake and said discharge channels constitute a drying circuit with the interior of said basket;

fan means in operative association with said drying circuit for drawing air from the exterior of the dryer into said intake channel;

a flexible air-hose mounted to the dryer and defining a first hot-air utility opening at one end thereof communicating with the exterior of the dryer;

a nozzle defining a second hot-air utility opening at one end thereof communicating with the exterior of the dryer;

a grill mounted to the dryer at the outside thereof and defining a third hot-air utility opening communicating with the exterior of the dryer;

at least one hot-air utility conduit communicating with said hot-air utility openings, and with said drying circuit at a location downstream of said heating means with respect to the direction in which air will be induced to flow through the drying circuit by said fan means; and

selection control means for selectively respectively opening said hot-air utility openings to said drying circuit while closing said discharge channel, and collectively closing said hot-air utility openings to said drying circuit while opening said discharge channel.

10. A clothes dryer as claimed in claim 9, wherein said selection control means is operatively connected to said fan means and to said heater means to control the operation thereof independently of one another, said selection control means is operable to place the dryer in an aspiration mode in which said hot-air utility openings are closed to said drying circuit, said discharge channel is open, and said fan means is operated while said heater means is not operated, and said selection control means includes a switch on the dryer which is manually operable to establish said aspiration mode.

11. A clothes dryer as claimed in claim 9, wherein said at least one hot-air utility conduit is a single conduit communicating with each of said hot-air utility openings, said selection control means includes a deflector disposed at said location at which said single conduit communicates with said drying circuit, said deflector being movable between a first position at which said deflector blocks the flow of air through said drying circuit while opening said single conduit to said drying circuit and a second position at which the deflector closes said single conduit to said drying circuit, and a gate disposed in said single conduit, said gate having an aperture extending therethrough, and said gate being movable between respective positions at which said aperture is placed in communication with one of said hot-air utility openings while the gate closes the others of said hot-air utility openings to said single conduit.
