the spraying component is controlled to spray alternately in a spraying and stopping mode, and meanwhile, the clothes treating part is controlled to rotate in a mode that the rotating speed is gradually increased and the rotating time length is gradually decreased when the spraying component sprays.

4. The underwear washing control method of a washing machine as claimed in claim 1, wherein the washing course includes a first washing stage and a second washing stage;

wherein the first washing stage comprises: controlling the clothes treating piece to rotate in a mode that the rotating speed is gradually increased and the rotating time length is gradually decreased, and simultaneously controlling the spraying component to spray in a mode that the spraying time length is gradually decreased;

the second washing stage comprises: the spraying component is controlled to spray alternately in a spraying and spraying stopping mode, and meanwhile, the clothes treating part is controlled to rotate in a mode that the rotating speed is gradually increased and the rotating time length is gradually decreased when the spraying component sprays.

5. An underwear washing control method of a washing machine as claimed in any one of claims 2 or 4, wherein the first washing stage comprises:

controlling a first rotating speed, a second rotating speed and a third rotating speed of the clothes treating part in sequence, correspondingly controlling a first rotating time, a second rotating time and a third rotating time of the clothes treating part in sequence, controlling a first spraying time, a second spraying time and a third spraying time of the spraying member in sequence, and controlling a first stopping time, a second stopping time and a third stopping time of the spraying member in sequence;

the first rotating speed, the second rotating speed and the third rotating speed are increased in an arithmetic progression; the first rotation duration, the second rotation duration and the third rotation duration are decreased in an equal ratio series; the first stop duration, the second stop duration, and the third stop duration are equal.

6. An underwear washing control method of a washing machine as claimed in any one of claims 3 or 4, wherein the second washing stage comprises:

controlling the spraying component to spray in a fourth spraying time length and a fourth stopping time length, controlling the clothes treatment part to sequentially run at a fourth rotating speed, a fifth rotating speed and a sixth rotating speed when the spraying component sprays, and correspondingly controlling the clothes treatment part to sequentially run at the fourth rotating time length, the fifth rotating time length and the sixth rotating time length;

stopping the laundry treating member for a fourth stop period after rotating at a sixth rotation speed for a sixth rotation period;

the fourth rotating speed, the fifth rotating speed and the sixth rotating speed are increased in an arithmetic progression; the fourth rotation time length, the fifth rotation time length and the sixth rotation time length are decreased in an equal ratio series;

the fourth spraying time period is the sum of the fourth rotation time period, the fifth rotation time period and the sixth rotation time period.

7. A washing machine, characterized by comprising:

an outer tub; the bottom and the side part of the outer barrel are enclosed into a water storage cavity which is divided into a first washing area and a second washing area;

a laundry treating member constituting a cylindrical structure rotatably provided in the outer tub; the clothes treating member includes an outer circumferential portion provided in the first washing zone and formed with a fluid-permeable clothes supporting structure on which underwear is supported; the inner periphery part is arranged in the second washing area;

a spray member including a first spray arm provided outside the outer peripheral portion and a second spray arm provided inside the outer peripheral portion;

a controller for performing the undergarment washing control method of any one of claims 1 to 6;

when the underwear is washed, the clothing processing piece is driven to rotate, the underwear rotates along with the clothing processing piece, and then the underwear is washed in a rotating mode; and water in the first spray arm and the second spray arm is respectively sprayed to the front side and the back side of the underwear and sprayed for washing.

8. The washing machine as claimed in claim 7, wherein a drain outlet is provided at the bottom of the outer tub, and a water inlet is provided at the bottom of the spray member; a first water inlet pipe, a pump and a second water inlet pipe are sequentially connected between the water inlet and the water outlet, and a circulating spraying pipeline is formed between the outer barrel and the spraying component; in the spin washing and spray washing processes, water in the outer tub may be recycled.

9. A washing machine as claimed in claim 8 wherein the bottom of the inner peripheral portion is connected to a drive means.

10. A washing machine as claimed in claim 9 wherein the garment support structure is provided with a grid structure formed with garment contours; an annular groove is formed at the bottom of the peripheral part, and water stirring ribs are formed in the annular groove;

when underwear is washed, water in the outer barrel enters the annular groove, and then is stirred towards and washes the underwear on the underwear supporting structure under the action of the water stirring ribs.
