  However, in the above-described conventional configuration, the operation of the other washing tub is not started until one of the washing tubs completes the drainage process, so that there is a problem that the operation time becomes long.

  The present disclosure solves the above-described conventional problems, and provides a drum-type washing machine that suppresses an increase in operating time.

  A drum type washing machine according to the present disclosure includes a housing, a first washing tub elastically supported in the housing, and a first washing tub that is rotatably provided in the first washing tub and accommodates laundry. A storage tank, a motor for rotating the storage tank, a first drainage path for discharging drainage from the first washing tank to the outside of the machine by opening and closing a first drain valve, and the first washing tank A second washing tub disposed below the second washing tub, a second storage tub disposed in the second washing tub for storing laundry, and drainage from the second washing tub A second drainage path and a drainage pump provided in the second drainage path are provided. An overflow port for discharging water is provided in an upper portion of the first storage tank, the second drainage path is raised vertically upward and bent at the uppermost portion, and the uppermost portion is the first portion. It is located above the lower end of the second washing tub and below the overflow port, extends vertically downward from the uppermost portion, and joins with the first drainage path.

  The drum type washing machine according to the present disclosure can suppress a long operating time.

The schematic block diagram of the drum type washing machine in embodiment of this invention. Perspective view of the internal structure of a conventional drum type washing machine

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to this embodiment.

(Embodiment 1)
FIG. 1 is a schematic configuration diagram of a drum type washing machine according to an embodiment of the present invention.

  In FIG. 1, a first washing tub 4 that rotatably encloses a bottomed cylindrical rotary drum 3 whose rotation axis is substantially horizontal is provided in a substantially box-shaped housing 1 by a damper structure (not shown). Elastically supported. The rotary drum 3 for containing the laundry is rotationally driven by the motor 21 on the rear side.

  A door body 2 for loading and unloading laundry from the rotary drum 3 is provided on the front side of the housing 1 so as to be openable and closable.

  In addition, the first drainage port 5 provided with a drainage trap 25 for preventing a sewage odor from entering the route is provided at the first drainage port 27 provided in the lower portion of the first washing tub 4. It is connected and opened / closed by the first drain valve 6.

  The first washing tub 4 is provided with an overflow port 11 at a position higher than the washing water level A, and the water overflowing from the overflow port 11 is drained to the middle of the first drainage path 5.

  A second washing tub 7 independent of the first washing tub 4 is arranged below the first washing tub 4. A storage portion 8 for storing the laundry is arranged in the second washing tub 7, and the storage portion door body 24 provided in the housing 1 can be opened and closed to be pulled out.

  Inside the second washing tub 7, a pressing body of a laundry pressing mechanism (not shown) performs up and down push-washing operations on the laundry stored in the storage section 8 to perform washing and rinsing operations to wash the laundry. The water can be dehydrated by squeezing it by pressing it strongly.

  Further, the second drainage port 28 provided in the lower portion of the second washing tub 7 is connected to the second drainage route 9 in which the drainage pump 10 is provided. Then, the second drainage path 9 rises to an upper position in the housing 1, the uppermost portion 29 is located above the washing water level A of the first washing tub 4, and the first washing tub 4 is It is located below the overflow port 11. The drainage is piped downward after being started up, and merges with the first drainage path 5 at the drainage merge section 26.

  A control device 23 is arranged inside the housing 1, and when a start of operation is set from the operation display unit 22 on the front surface of the housing 1, a water supply valve (not shown), a motor 21, a first The operations of the drain valve 6, the laundry pressing mechanism (not shown), the drain pump 10, and the like are controlled to control each process such as washing, rinsing, and dehydrating.

  With the above configuration, in the operation process, the water supplied from the water supply valve (not shown) takes in the detergent supplied from the detergent supply unit (not shown) and stores the laundry as the washing water. It is supplied into the washing tub 4 of.

By rotating the rotating drum 3 inside the first washing tub 4, washing, rinsing,
Each process of dehydration is executed.

  Then, in the drainage process, the first drainage valve 6 provided below the first washing tub 4 opens the first drainage path 5, so that the water in the first washing tub 4 becomes The water is discharged from the drain port 27 through the first drainage path 5 like the drainage flow a to the outside of the machine by natural drainage.

  On the other hand, the water supplied from the water supply unit (not shown) takes in the detergent supplied from the detergent supply unit (not shown) and is also supplied as washing water into the second washing tub 7.

  Inside the second washing tub 7, a pressing body of a laundry pressing mechanism (not shown) performs a washing operation and a rinsing operation by adding up and down push-washing operations to the laundry stored in the storage section 8 Then, the drainage pump 10 provided in the second drainage route 9 operates, and the water discharged from the second drainage port 28 passes through the second drainage route 9 and is discharged to the outside like the drainage flow b. It

  The washing, rinsing, and dehydrating operations in each washing tub are independent of each other, and the first washing tub 4 and the second washing tub 7 can be operated independently or simultaneously. Is becoming

  In the process of both washing tubs, when the draining process of the first washing tub 4 and the draining process of the second washing tub 7 occur at the same time, the drainage flow a from the first washing tub 4 which is natural drainage is At the drainage confluence section 26, the water velocity is fast due to the operation of the drainage pump 10, and the drainage confluence section 26 pulls the drainage stream b flowing downward, and the water is also drained out of the machine.

  That is, the drainage does not flow back from the first washing tub 4 to the second washing tub 7 through the drainage path, and the drainage does not flow back from the second washing tub 7 to the first washing tub 4.

  Further, since it is not necessary to shift the drainage of the first washing tub 4 and the drainage of the second washing tub 7 in time, an extra delay time does not occur, and an excessive increase in operating time can be prevented. ..

  As described above, in the drum type washing machine according to the present embodiment, the second drainage route 9 that is the drainage route of the second washing tub 7 and provided with the drainage pump 10 stands in the upper position in the housing 1. The uppermost part 29 is raised and is located above the washing water level of the first washing tub 4 and below the overflow port 11 of the first washing tub 4, and is piped downward after being raised. Then, it joins with the first drainage path 5 which is the drainage path of the first washing tub 4. As a result, the operating time is not excessively increased due to unnecessary delay time. Further, it is possible to prevent the drainage of one washing tub from flowing back to the other washing tub.

  In addition, in this Embodiment, the rotating drum 3 which is a 1st storage tank and the storage part 8 which is a 2nd storage tank were demonstrated. The first storage tank may be a vertical storage tank or a rotary drum. The second storage tank may also be a vertical storage tank or a rotary drum.

  The present disclosure can be applied to a washing machine having a plurality of storage tanks. Specifically, the present disclosure is applicable to a washing machine in which at least one of the storage tubs is opened vertically upward, a washing machine in which at least one of the storage tubs is opened horizontally or with a central axis inclined. Is.
