  The control means 34 includes an output of the cloth amount detection means 35 for detecting the amount of the laundry 28 put in the drums 4a and 4b, and a water level detection means 36 for detecting the amount of the washing water supplied into the outer tub 1. , The output of the rotation detecting means 37 for detecting the drive of the motor 19, and the output of the water temperature detecting means 38 for detecting the temperature of the washing water.

  About the drum type washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Washing is sequentially performed in the order of washing, rinsing and dehydration according to a program preset by the control means 34.

  First, a case where the laundry is separately washed will be described. For example, a laundry with a lot of dirt and a laundry with a little dirt can be separately washed in one wash. First, after opening the door 33 provided on the upper surface of the housing 2, the outer lid 31 and the inner lid 30 are opened and the laundry is put into the drums 4a and 4b.

  At this time, the laundry with a lot of dirt and the laundry with a little dirt are put in separately. For example, the laundry 28 with much dirt is put into the drum 4a, and the laundry 28 with little dirt is put into the drum 4b. The laundry 28 put into the drums 4a and 4b is positioned on the outer surface 16a side of the drum 4a and the outer surface 16b side of the drum 4b with the partition 7 as a boundary.

  A power switch (not shown) of the operation display unit 39 provided on the upper surface of the housing 2 is turned on, and a start switch (not shown) is operated to start operation. When the operation is started, the amount of the laundry 28 put in the drums 4a and 4b is detected by the cloth amount detecting means 35. The amount of the laundry 28 can be detected from the amount of torque applied to the motor 19 or the current value of the motor 19 when the drums 4a and 4b are rotated and driven.

The control means 34 sets the time for each step such as washing, rinsing, and dehydration according to the detected amount of laundry 28, and operates a preset amount of detergent according to the amount of laundry 28. It is displayed on the display unit 39. The user puts the detergent into the detergent throwing part (not shown) according to the displayed guideline for the amount of detergent. The detergent may be loaded automatically by the control means 34 with a general detergent automatic loading device mounted.

  Further, a predetermined amount of washing water is supplied according to the amount of laundry. Washing water is supplied into the outer tub 1 from the upper part of the peripheral wall 1a of the outer tub 1 through the water supply valves 23a and 23b from the water supply section 22 connected to a water tap or the like, and is stored at the bottom of the outer tub 1 Stored in the parts 6a and 6b. The washing water supplied into the outer tub 1 is detected by the water level detection means 36, and when the amount of washing water set according to the amount of the laundry 28 is accumulated, the water supply is stopped.

  The rated water level L of the washing water stored in the water storage sections 6a and 6b partitioned by the partition section 7 is set so as to be located below the upper end section 7a (arc-shaped inner side) of the partition section 7 formed in an arc shape. ing. Accordingly, the peripheral wall portions 14a and 14b of the drums 4a and 4b disposed above the upper end portion 7a of the partitioning portion 7 are located above the rated water level L of the washing water and are not immersed in the stored washing water. The resistance during rotation of the drums 4a and 4b is reduced, and the power consumption of the motor 19 is reduced.

  Following the supply of the washing water, the motor 19 and the pumps 26a and 26b are driven. The motor 19 is driven so that the laundry 28 is lifted in the rotation direction of the drums 4a and 4b and is rotated forward and backward at a rotation speed, for example, 45 rpm, which performs a tumbling operation in which the laundry drops from the upper part of the drums 4a and 4b. To drive.

  The washing water stored in the water storage section 6a reaches the pump 26a through the water supply path 24a from the water inlet 25a provided at the bottom of the water storage section 6a, and is driven into the drum 4a through the water supply path 24a by driving the pump 26a. Water is circulated.

  The washing water stored in the water storage section 6b reaches the pump 26b through the water supply path 24b from the water inlet 25b provided at the bottom of the water storage section 6b, and is driven into the drum 4b through the water supply path 24b by driving the pump 26b. Water is circulated.

  As a result, the laundry 28 does not move in the direction of the rotary shaft 5 and is tumbled by the rotation of the drums 4a and 4b that rotate about the rotary shaft 5 provided substantially horizontally. The laundry 28 is difficult to mix. In addition, since the wash water is separated into the water storage section 6a and the water storage section 6b via the partition section 7, the wash water fed to the drum 4a circulates back to the water storage section 6a, and also into the drum 4b. The sent wash water returns to the water storage section 6b and circulates.

  Accordingly, the washing water contained in each of the laundry 28 divided into the drum 4a and the drum 4b can be washed without being mixed with each other during the washing operation.

  Next, a case where the laundry is washed together without dividing the laundry will be described. As in the case of separate washing, after the door 33 provided on the upper surface of the housing 2 is opened, the outer lid 31 and the inner lid 30 are opened, and the laundry is put into the drums 4a and 4b.

  Washing water is supplied into the outer tub 1 through the water supply valves 23a and 23b, and is stored in water storage portions 6a and 6b provided at the bottom of the outer tub 1. The water storage parts 6a and 6b communicate with each other through the communication part 9 opened by the communication doors 10a and 10b, and approximately the same amount of washing water is stored in each of the water storage parts 6a and 6b.

The washing water stored in the water storage units 6a and 6b is driven by the pumps 26a and 26b from the water intake ports 25a and 25b provided at the bottoms of the water storage units 6a and 6b, respectively, through the water supply channels 24a and 24b, and the drums 4a and 24b. Water is circulated in 4b. In the washing process and the rinsing process, the washing water is stored in the water storage units 6a, 6 by rotating the drums 4a, 4b and driving the pumps 26a, 26b.
Approximately the same amount of washing water is retained in b.

  The peripheral wall portions 14a and 14b of the drums 4a and 4b are disposed above the partition portion 7, and the rated water level L of the washing water stored in the water storage portions 6a and 6b is set below the upper end portion 7a of the partition portion 7. Therefore, the peripheral wall portions 14a and 14b of the drums 4a and 4b are not immersed in the washing water stored in the water storage portions 6a and 6b.

  As a result, the peripheral walls 14a and 14b of the drums 4a and 4b can be brought close to a flat shape, and when the laundry 28 is washed together, the annoyance of distributing and putting the laundry 28 in the same amount is eliminated. Therefore, it is possible to improve usability, and it is possible to achieve both convenience of separate washing and batch washing.

  Note that the temperature of the washing water supplied from the water supply unit 22 into the outer tub 1 is detected by a water temperature detecting means 38 constituted by a thermistor or the like, and when the water temperature is low, the washing water is heated by the heater 29 (for example, 40 ℃) and washing effect with warm water can enhance the washing effect.

  At this time, when the amount of the laundry 28 is small and washing is performed with only one drum 4b, the communication door 10b is closed and water is supplied from the water supply valve 23b to the water storage section 6b. Thereby, a small amount of washing water supplied according to the amount of the laundry 28 can be efficiently heated and washed.

  Moreover, when supplying water to both the water storage parts 6a and 6b and performing washing together, the communicating water 10a and 10b can be opened and the wash water in the water storage parts 6a and 6b can be heated simultaneously.

  As described above, in the present embodiment, the outer tub 1 elastically supported in the housing 2 and the outer tub 1 are rotatably provided in the outer tub 1 and pass through the water holes 15a, 15b, 17a, 17b.

The washing water in 6a, 6b is introduced into the drums 4a, 4b through the water supply channels 24a, 24b and circulated, and the peripheral wall portions 14a, 14b of the drums 4a, 4b can be brought closer to a flat shape, When washing laundry in bulk, it is possible to eliminate the hassle of allocating and throwing in the same amount of laundry and improve usability, making it possible to achieve both convenience of separate washing and collective washing it can. Further, after the laundry is lifted in the rotation direction of the drums 4a and 4b, the laundry is dropped by gravity from above in the drums 4a and 4b and is hit against the peripheral wall portions 14a and 14b in the lower part in the drums 4a and 4b. The washing water can be supplied to the laundry at the upper part of the drums 4a and 4b, and the laundry can be dropped downward in a state including a large amount of washing water, which acts on the laundry. The mechanical effect can be increased to improve the cleaning effect by tapping.

In addition, outlets 24c and 24d for washing water discharged from the water supply channels 24a and 24b are provided in the outer tub 1 so as to face the outer surface portions 16a and 16b of the drums 4a and 4b, and on the outer surface portions 16a16b of the drums 4a and 4b.
