Washing machine and dryer
The present disclosure relates to a washing machine with a drying function, capable of performing a washing program and a drying program. The machine comprises a cabinet ( 1 ), a tub ( 9 ) in the cabinet and a door ( 3 ), through which access to the tub interior can be achieved, and further an air evacuation chamber ( 37 ) which comprises an upper section ( 59 ) and a lower section ( 57 ), wherein the upper section is connected to the tub in order to allow an air flow from the tub to the upper section, and the upper section is connected to the lower section at a connection point which is higher than the maximum water level during the washing program, such that air can flow to the lower section during the drying program while water is prevented from flowing from the tub to the lower section during the washing program. This allows the lower part to contain parts of the drying system that are to be kept dry, which allows a more compact machine to be built.
1. A washing machine with a drying function, capable of performing a washing program and a drying program, comprising a cabinet ( 1 ), a tub ( 9 ; 9 ′) in the cabinet and a door ( 3 ), through which access to the tub interior can be achieved, characterized by an air evacuation chamber ( 37 ; 37 ′) which comprises an upper section ( 59 ; 59 ′) and a lower section ( 57 ; 57 ′), wherein the upper section ( 59 ; 59 ′) is connected to the tub ( 9 ; 9 ′) by openings ( 49 ) in order to allow an air flow directly from the tub ( 9 ; 9 ′) to the upper section ( 59 ; 59 ′), and the upper section ( 59 ; 59 ′) is connected to the lower section ( 57 ; 57 ′) at a connection point which is higher than the maximum water level during the washing program, such that air can flow to the lower section during the drying program while water is prevented from flowing from the tub ( 9 ; 9 ′) to the lower section ( 57 ; 57 ′) during the washing program.
2. A washing machine according to claim 1 , wherein a lint filter unit ( 61 ) is connected to the lower section ( 57 ) and is located lower than the maximum water level during the washing program.
3. A washing machine according to claim 1 , wherein a blower ( 19 ) is connected to the lower section ( 57 ) and is located lower than the maximum water level during the washing program.
4. A washing machine according to claim 1 comprising two water level sensors.
5. A washing machine according to claim 1 , wherein the chamber is located at a front part of the machine so that air leaves the tub at a front part of the machine.
6. A washing machine according to claim 1 , wherein the openings connect at a point that is higher than the maximum water level during the washing program.
7. A washing machine according to claim 1 , further comprising a blower configured to move air from the upper section to the lower section.
8. A washing machine according to claim 1 , wherein the lower section is configured to convey air to an exterior of the washing machine.
9. A washing machine according to claim 1 , further comprising a door allowing access to an interior of the tub, wherein the air evacuation chamber has an outer dimension greater than an outer dimension of the door.
10. A washing machine according to claim 1 , further comprising at least one ambient air inlet configured for admitting ambient air to the machine and a heating device configured for heating the ambient air before the air enters the tub.
11. A washing machine with a drying function, capable of performing a washing program and a drying program, comprising a cabinet ( 1 ), a tub ( 9 ; 9 ′) in the cabinet and a door ( 3 ), through which access to the tub interior can be achieved, characterized by an air evacuation chamber ( 37 ; 37 ′) which comprises an upper section ( 59 ; 59 ′) and a lower section ( 57 ; 57 ′), wherein the upper section ( 59 ; 59 ′) is connected to the tub ( 9 ; 9 ′) in order to allow an air flow from the tub ( 9 ; 9 ′) to the upper section ( 59 ; 59 ′), and the upper section ( 59 ; 59 ′) is connected to the lower section ( 57 ; 57 ′) at a connection point which is higher than the maximum water level during the washing program, such that air can flow to the lower section during the drying program while water is prevented from flowing from the tub ( 9 ; 9 ′) to the lower section ( 57 ; 57 ′) during the washing program, wherein the air evacuation chamber ( 37 ; 37 ′) is arranged as an annular chamber, surrounding the door ( 3 ).
12. A washing machine according to claim 11 , wherein the evacuation chamber ( 37 ) is defined between a cylindrical wall ( 39 ) of the tub ( 9 ), a cylindrical collar plate ( 47 ) surrounding the door, an inner front wall ( 43 ) and an outer front wall ( 45 ).
13. A washing machine according to claim 12 , wherein the evacuation chamber ( 37 ) is divided into the upper section ( 59 ) and the lower section ( 57 ) by means of side plates ( 53 , 55 ) attached to and extending sideways and upwards from the collar plate ( 47 ), and where openings ( 49 ) are provided in the collar plate ( 47 ) over the location where the side plates ( 53 , 55 ) are attached.
