For example, in the first embodiment, four airbags are arranged on the side surface in the washing case 3, and in the second embodiment, five airbags are arranged on the side surface and the bottom surface in the washing case 3. Not limited to them. That is, in the push-washing type washing machine of the present invention, the number of airbags arranged in the washing case 3 is arbitrary, and for example, one airbag may be arranged in the washing case 3. The arrangement of one or more airbags in the washing case 3 is arbitrary.

In the first and second embodiments described above, airbags made of polyester have been described, but the present invention is not limited thereto. In the push-washing washing machine of the present invention, the material, thickness, shape, and size of the airbag are arbitrary.

The first embodiment has one air pump 10 and two solenoids C1 and C2 connected to the air pump 10, and the second embodiment has one air pump 10 and three solenoids C1 and C2 connected to the air pump 10. , C3, but not limited to them. In the push-wash type washing machine of the present invention, if it is possible to switch between a state in which air is supplied and a state in which air is discharged to the outside for a plurality of airbags, the number of air pumps, the number of solenoids, and the air pumps and solenoids. The connection method is arbitrary.

In the first embodiment, the solenoid C1 is connected to the airbags A1 and A2, the solenoid C2 is connected to the airbags A3 and A4, and the airbags A1 and A2 are simultaneously expanded and contracted by the solenoid C1. The case where the airbags A3 and A4 are controlled to expand and contract at the same time by the solenoid C2 has been described, but the present invention is not limited thereto.

For example, in the first embodiment, by changing the connection method between the two solenoids C1 and C2 and the four airbags A1, A2, A3 and A4, an operation pattern other than the above two operation patterns becomes possible. .. That is, in the push-washing type washing machine of the present invention, the operation pattern and the washing pattern can be arbitrarily set. The same applies to the second embodiment.

For example, by connecting two solenoids C1 and C2 to one air pump 10, connecting the solenoids C1 to the airbags A1 and A4, and connecting the solenoids C2 to the airbags A2 and A3, the airbags A1 and A1 are connected by the solenoid C1. An operation pattern is possible in which the airbags A2 and A3 are controlled to expand and contract at the same time by the solenoid C2 while the A4 expands and contracts at the same time.

(Airbag side top and bottom alternating operation pattern)
In the operation pattern shown in FIG. 13, the upper airbag A1 and the lower airbag A4 are simultaneously inflated or contracted, and the upper airbag A2 and the lower airbag A3 are simultaneously inflated. It is an operation pattern that shrinks.

_At time T1, the solenoid C1 is turned on and the solenoid C2 is turned off, and the air from the air pump 10 is supplied to the airbags A1 and A4, respectively. Therefore, in the washing case 3, the airbags A1 and A4 Is in a state of swelling toward the center of the washing case 3 and pressing the laundry. At that time, since the air in the airbags A2 and A3 is discharged to the outside, in the washing case 3, the airbags A2 and A3 shrink along the inner peripheral surface of the washing case 3 to shrink the laundry. It will not be pressed.

At time T2 when the _first predetermined time has elapsed from time T1, the solenoid C1 is turned off and the solenoid _C2 is turned on, and the air from the air pump 10 is supplied to the airbags A2 and A3, respectively, so that the laundry is washed. In the case 3, the airbags A2 and A3 swell toward the center of the washing case 3 and press the laundry. At that time, since the air in the airbags A1 and A4 is discharged to the outside, in the washing case 3, the airbags A1 and A4 shrink along the inner peripheral surface of the washing case 3 to shrink the laundry. It will not be pressed.

At time T3 when the _second predetermined time has elapsed from time T2 _, the solenoid C1 is turned on and the solenoid C2 is turned off, and the air bags A1 and A4 inflate and press the laundry in the washing case 3. The air bags A2 and A3 are in a state of shrinking and not pressing the laundry. After that, similarly, the airbags A1 and A4 and the airbags A2 and A3 alternately repeat the state of not pressing the laundry and the state of pressing the laundry.

Further, in the push-washing washing machine 101 of the second embodiment, as shown in FIG. 14, the airbags A1 to A4 arranged on the side surface of the washing case 3 and the air arranged on the bottom surface of the washing case 3 The bag A5 and the bag A5 may be controlled to inflate and contract at the same time.

In the first embodiment, four solenoids are connected to one air pump 10, the four solenoids are connected to each of the four airbags, and the four solenoids are switched to an on state or an off state, respectively. Each of the four airbags may be controlled to inflate and contract separately. The same applies to the second embodiment.
