The first pump 30 having such a configuration is disposed above a stepped portion 29a formed at the upper and lower middle portion of the first tank 29, as shown in FIG. The connection tube 45 is inserted into the first tank 29, and the tip thereof is located at the inner bottom of the first tank 29. The other connection tube 46 has a distal end connected to a position below the detergent port 27 of the water injection case 21.

As shown in FIG. 4, the second pump 32
The second pump 32 has the same configuration as the first pump 30. Connection tubes 47 and 48 are connected to the connection pipes 44a and 44b, respectively. Further, like the first pump 30, the second pump 32 is entirely disposed above a step (not shown in detail) formed at the upper and lower middle part of the second tank 31.

The other connection connection tube 48 is piped along the inner peripheral portion of the top cover 3, and has a distal end connected to a position below the detergent passage 27 of the water injection case 21 similarly to the connection tube 46.

Next, the operation of the above configuration will be described. First, whether to supply the detergent and the cleaning aid with the detergent input device 9 and the drawer 28 or with the pumps 30 and 32 is selected by the operation of the operation panel 8 by the user. I have. Assuming that the supply of the detergent and the cleaning aid is selected to be performed by the pumps 30 and 32, when the operation is started and the washing process is started, the amount and the quality of the laundry are detected. The washing water level is determined from the result, and the supply amounts of the detergent and the cleaning aid are determined accordingly.

Thereafter, the washing tub 6 is passed through the first water outlet 24 of the water supply valve 20 through the water path indicated by the arrow A in FIG.
Water is supplied thereinto, and the motor 40 of the first pump 30 is started slightly later or at the same time as, or slightly earlier than, that is, almost simultaneously with this water supply. When the motor 40 is started, the driving wheel 42 is rotated, particularly eccentrically, by the rotating shaft 40a shown in FIG. 1, and the roller 38 is also rotated, particularly, eccentrically.

The rotation direction of the roller 38 is a counterclockwise direction indicated by an arrow C in FIG.
The part to be pressed of the liquid feeding tube 39 is sequentially moved in the rotation direction as shown in FIGS. Thereby, the liquid sending tube 3
9 is sent to the other connection tube 46 which is the destination side, and a liquid detergent corresponding to the air is sent from the first tank 29 storing this through one connection tube 45. It is sucked into the tube 39.

Thereafter, as the rotation of the roller 38 continues, the portion to be pressed by the liquid feed tube 39 is also sequentially shifted in the direction of rotation, whereby the liquid detergent in the first tank 29 is sequentially fed. The water is sent to the other connecting tube 46 side through the tube 39, and further sent from the connecting tube 46 to a position below the detergent inlet 27 of the water injection case 21. The liquid detergent sent to a position below the detergent inlet 27 of the water injection case 21 is diluted with water flowing therethrough,
The water is supplied into the washing tub 6 from the outlet of the water injection case 21 together with the water.

The supply amount of the detergent is determined by controlling the energizing time to the motor 40 and controlling the number of rotations of the roller 38. In addition, the determination of the supply amount of the detergent is performed by detecting the permeability of the washing water supplied into the washing tub 6 and immersed in the laundry. You may make it determine according to the turbidity of water.

Further, in the case of this embodiment, the washing tub 6
The remaining hot water in the bath can be supplied by the water supply pump 19, and when the remaining hot water in the bath is supplied, it is determined that more detergent is supplied than when the tap water is supplied. The same washing effect as when washing may be obtained.

In the final rinsing step of the rinsing step performed a plurality of times, the motor 40 of the second pump 32 is started almost simultaneously with the supply of water into the washing tub 6 as described above. Therefore, also in this case, the roller 38 is rotated, in particular, eccentrically rotated, so that the portion to be pressed by the liquid feeding tube 39 is sequentially moved in the rotation direction, thereby assisting the cleaning of the liquid in the second tank 31. The agent is sequentially sent to the other connecting tube 48 side through the liquid sending tube 39, and further sent from the connecting tube 48 to a position below the detergent inlet 27 of the water injection case 21. This water injection case 21
The liquid cleaning aid sent to a position below the detergent inlet 27 is diluted with water flowing therethrough and supplied to the washing tub 6 from the outlet of the water injection case 21 together with the water, similarly to the aforementioned detergent. .

And the soft liquid feed tubes 39 communicating with the first and second tanks 29 and 3 respectively.
So-called tube-type first and second pumps 30 and 3 for transferring liquid by sequentially transferring the liquid from the first side to the destination side, respectively.
2 and the pumps 30 and 32 supply the detergent in the first tank 29 and the cleaning aid in the second tank 31.

According to this method, there is no trouble that the detergent and the cleaning aid are stored in separate charging containers one by one, and further set in the water injection case one by one. The cleaning aid can be supplied as desired, and further, the supply amount does not vary as in the case of an air pump driven by a solenoid, and vibrations and noise can be supplied at a constant rate. In addition, the supply of the cleaning aid at a different time from the supply of the detergent can be supplied with a simple structure that does not require a dedicated water supply valve or a water supply structure.

In particular, in the case of the above configuration, the pressing of the liquid feeding tube 39 in the first and second pumps 30 and 32 is performed by the liquid feeding tube 39 disposed along the annular peripheral wall 41 a of the concave portion 41 of the case 37. The peripheral wall 4 of the concave portion 41 of the case 37 is
1a, the liquid supply tube 39 can be pressed strongly between the rotating roller 38 and the peripheral wall 41a of the concave portion 41 of the case 37. Detergent or liquid cleaning aids can be supplied reliably, and thus accurately in metered amounts.
