Drum-type washing machine

Abstract

To provide a drum-type washing machine capable of preventing a pack-type detergent from remaining undissolved in a door packing.SOLUTION: A drum-type washing machine 1 comprises: an outer tank 20 disposed in a housing 10; an annular door packing 24 disposed between an input port 11 of the housing 10 and an opening 20a of the outer tank 20; a drum 23 disposed in the outer tank 20; a drive motor 30 for rotating the drum 23; a water supply device 50 for supplying water into the outer tank 20; and a control part. In a washing step, the control part causes the water supply device 50 to supply water into the outer tank 20, causes the drive motor 30 to rotate the drum 23 at a first rotation speed after the water supply, determines whether or not dissolution of a pack-type detergent put in the drum-type washing machine 1 is insufficient after the drum 23 is rotated at the first rotation speed, and causes the drive motor 30 to rotate the drum 23 at a second rotation speed higher than the first rotation speed when determining that the dissolution of the pack-type detergent is insufficient.SELECTED DRAWING: Figure 1

Claims

1. In a drum-type washing machine that can use a pack-type detergent having a configuration in which the detergent is sealed in a water-soluble pack, The casing and An input slot provided on the front of the aforementioned housing, A door covering the aforementioned input opening, An outer tank arranged inside the aforementioned housing, An opening provided on the front surface of the outer tank, An annular door packing provided between the input opening and the opening, A drum is placed inside the outer tub and contains laundry, A drive motor for rotating the drum, A water supply device that supplies water into the outer tank, It comprises a control unit that performs a washing operation including a washing process, a rinsing process and a spin-drying process, The control unit, in the washing process, The water supply device supplies water into the outer tank, After the water supply, the drive motor rotates the drum at a first rotational speed. After the drum has been rotated at the first rotation speed, it is determined whether or not the pack-type detergent put into the drum-type washing machine is insufficiently dissolved. If it is determined that the pack-type detergent is not sufficiently dissolved, the drive motor rotates the drum at a second rotational speed higher than the first rotational speed. A drum-type washing machine characterized by the following features.

2. In the drum washing machine according to claim 1, The water supply device includes a water discharge section that discharges water toward the door, When the control unit determines that the pack-type detergent is not sufficiently dissolved, it rotates the drum at the second rotation speed and discharges water from the water discharge unit. A drum-type washing machine characterized by the following features.

3. In the drum-type washing machine according to claim 1 or 2, The control unit, After rotating the drum at the second rotation speed, it is determined whether or not the pack-type detergent is insufficiently dissolved. Based on the determination that the aforementioned packaged detergent is insufficiently dissolved, the notification unit is instructed to issue a notification indicating that the packaged detergent is insufficiently dissolved. A drum-type washing machine characterized by the following features.

4. In the drum-type washing machine described in claim 3, The control unit, After the notification unit issues a notification indicating insufficient dissolution of the pack-type detergent, the drive motor rotates the drum at a third rotational speed. While the drum is rotating at the third rotational speed, it is determined whether or not the water in the outer tub contains the detergent. If it is determined that the water in the outer tank does not contain the detergent, the notification unit will issue a notification indicating that the pack-type detergent has been forgotten to be added. A drum-type washing machine characterized by the following features.

5. In the drum-type washing machine according to claim 1 or 2, The system further includes an operating unit that accepts an operation for setting the system to use the aforementioned pack-type detergent, The control unit, when the setting to use the pack-type detergent is enabled, performs a determination as to whether or not the pack-type detergent is insufficiently dissolved. A drum-type washing machine characterized by the following features.
