Description

A WASHER-DRYER UTILIZING THE VOLUME INSIDE THE DOOR
The present invention relates to a washer-dryer utilizing the volume inside the loading door.
In washer-dryers, generally there are separate washing programs for laundries of cottons, synthetics, wools, and sensitives/delicates, and a program suitable for the type of the laundry should be chosen before washing process. Even though the user sorts the laundry according to types, problems may occur with some laundries during unloading after washing. Particularly small and delicate laundry such as socks, underwear, and baby clothes may get stuck between the drum and the bellows in the washing machine, and may be torn by being caught onto the bulge forms on the surface of the drum.
European patent no. EP2415920 (B1) relates to a washing machine in which laundry is loaded into the space inside the door.
The aim of the present invention is to realize a washing machine enabling effective washing of small and delicate laundries in the volume inside the loading door.
The washer-dryer realized to achieve the aim of the present invention comprises a door covering the loading opening enabling loading and unloading of the laundry, an outer window, and an inner window of cambered structure extending from the loading opening into the drum. The space between the outer window and the internal window is used as a washing chamber for washing delicate and small laundries. An ultrasonic transducer and a heater enabling washing the laundry without detergent, is placed in the washing chamber.
The washer-dryer realized to achieve the aims of the present invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a schematic view of the washer-dryer of the invention.
Figure 2 is a sectional view of the drum, tub and the washing chamber formed in the door,
provided in the washer-dryer.
The elements in the figures are numbered individually and the correspondence of these numbers are given hereinafter.
  1. Washer-dryer
  2. Body
  3. Drum
  4. Tub
  5. Door
  6. Detergent box
  7. Discharge pump
  8. Outer window
  9. Washing chamber
  10. Inner window
  11. Ultrasonic transducer
  12. Water supply line
  13. Water discharge line
  14. Heater
  15. Inner door
The washer-dryer (1) comprises a body (2), a drum (3) in which the laundry are placed, a tub (4) in which the drum (3) moves, a door (5) provided on the front face of the body (2), enabling the laundry to be loaded into and unloaded from the drum (3) by being opened and closed by the user, a detergent box (6) into which detergent is deposited and water is received from an external water mains, and a discharge pump (7) enabling discharging the washing water in the drum (3).
The door (5) comprises an outer window (8) covering its surface facing the outer side of the body (2), and an inner window (10) with a cambered structure extending into the drum (3), sealingly fixed to the outer window (8) along its annular edge, and forming a washing chamber (9) in the space between itself and the outer window (8) in which delicate and small sized laundry are placed in order to be washed. The washer-dryer (1) further comprises an inner door (15) which can be opened and closed on the inner window (10), enabling the laundry to be loaded to and unloaded from the washing chamber (9).
The washer-dryer (1) of the invention comprises an ultrasonic transducer (11) placed in the washing chamber (9) in the door (5), enabling removal of the dirt on the laundry in the washing chamber (9) through cavitation effect, by applying ultrasonic energy.
The washer-dryer (1) further comprises a water supply line (12) connected to the external water mains or the detergent box (6), enabling supplying water to the washing chamber (9), and a water discharge line (13) connected to the discharge pump (7), enabling discharging the water in he washing chamber (9).
In an embodiment of the invention, the washer-dryer (1) comprises a heater (14) placed in the washing chamber (9), enhancing the washing effect of the ultrasonic transducer (11) by heating the water in the washing chamber (9).
In another embodiment of the invention, the washer-dryer (1) comprises a transparent film type heater (14) placed on the internal surface of the inner window (10) and/or the outer window (9). Thus, the heater (14) does not form an obstruction for the user to monitor the laundry being washed in the washing chamber (9) in the door (5), and in the drum (3).
In the washer-dryer (1) of the invention, baby clothes, socks, delicate and small laundries are washed in the washing chamber (9) formed in the door (5). The washing chamber (9) is filled with washing water coming from the water supply line (12), whose amount is predetermined by means of a control unit and a valve (not shown in the figures). After the washing chamber (9) being filled up to a specified level, the control unit enables activation of the heater (14) and the ultrasonic transducer (11). The mechanical effect required to remove the dirt on the laundry in the washing chamber (9) is provided by the ultrasonic transducer (11). Ultrasonic cleaning is the process to clean an item in an environment, by applying high frequency sound waves in a liquid environment. In the washer-dryer (1), after completion of washing of predetermined duration in the washing chamber (9) formed in the door (5), the washing water drawn into the discharge pump (7) through the lower part of the washing chamber (9), is discharged by means of the water discharge line (13).
In the washer-dryer (1) of the invention, the dirt in the laundry placed in the washing chamber (9) in the door (5), is removed by the thermomechanical effect generated by the heater (14) and the ultrasonic transducer (11). Since the delicate and small laundry such as baby clothes and socks are washed in the washing chamber (9) in the door (5), instead of being washed in the drum (3), they are prevented from being stuck between the drum (3) and the bellows, and from being torn by being caught onto the bulge forms on the drum.
