Abstract

A washing and drying machine includes: a washing drum for accommodating the washings and rotating under a driving force of a motor; an air supply portion for supplying air into the washing drum; a heating portion configured to heat the air to be supplied into the washing drum when turned on and stop heating when turned off; and a control portion for controlling the motor, the air supply portion and the heating portion to execute a washing and drying operation. A drying procedure in the washing and drying operation includes main drying treatment repeated for multiple times. During each time of the main drying treatment, the control portion is configured to keep the heating portion being on within a first period, and keep the heating portion being off within a second period different from the first period, and the second period is longer than the first period.

First claim

What is claimed is:

1 . A washing and drying machine, comprising:
a motor for generating a driving force; a washing drum for accommodating washings and rotating under the driving force of the motor; an air supply portion for supplying air into the washing drum; a heating portion, configured to heat the air supplied into the washing drum when turned on and stop heating when turned off; and a controller for controlling the motor, the air supply portion and the heating portion to execute a washing and drying operation, wherein the washing and drying operation comprises: a washing procedure for washing the washings; a rinsing procedure for rinsing the washings after the washing procedure; a dewatering procedure for enabling the washing drum to rotate to dewater the washings after the rinsing procedure; and a drying procedure for drying the washings after the dewatering procedure; wherein the drying procedure comprises main drying treatment repeated for multiple times; and wherein during each time of the main drying treatment, the controller is configured to keep the heating portion being on within a first period, and keep the heating portion being off within a second period different from the first period; and wherein the second period is longer than the first period.

2 . The washing and drying machine according to claim 1 , further comprising:
a stirring member, configured to rotate under the driving force of the motor to stir the washings in the washing drum, wherein during each time of the main drying treatment, the controller is configured to enable the stirring member to rotate within a third period, or alternatively enable the washing drum to rotate within a fourth period different from the third period; and wherein the fourth period is shorter than the third period.

3 . The washing and drying machine according to claim 1 , further comprising:
a first setting circuit for setting a highest rotating speed of the washing drum in the drying procedure to be a first set value greater than a specified value.

4 . The washing and drying machine according to claim 1 , further comprising:
a second setting unitcircuit for setting the highest rotating speed of the washing drum in the dewatering procedure to be a second set value greater than the specified value.

5 . The washing and drying machine according to claim 1 , further comprising:
a third setting unitcircuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

6 . The washing and drying machine according to claim 1 , further comprising a pipe, configured to transmit the air into the washing drum;
wherein the air supply portion and the heating portion are successively disposed in the pipe.

7 . The washing and drying machine according to claim 2 , further comprising:
a first setting circuit for setting a highest rotating speed of the washing drum in the drying procedure to be a first set value greater than a specified value.

8 . The washing and drying machine according to claim 2 , further comprising:
a second setting circuit for setting the highest rotating speed of the washing drum in the dewatering procedure to be a second set value greater than the specified value.

9 . The washing and drying machine according to claim 3 , further comprising:
a second setting circuit for setting the highest rotating speed of the washing drum in the dewatering procedure to be a second set value greater than the specified value.

10 . The washing and drying machine according to claim 7 , further comprising:
a second setting circuit for setting the highest rotating speed of the washing drum in the dewatering procedure to be a second set value greater than the specified value.

11 . The washing and drying machine according to claim 2 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

12 . The washing and drying machine according to claim 3 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

13 . The washing and drying machine according to claim 7 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

14 . The washing and drying machine according to 4 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

15 . The washing and drying machine according to 8 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

16 . The washing and drying machine according to 9 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.

17 . The washing and drying machine according to 10 , further comprising:
a third setting circuit for setting treatment time from start to end of each time of the main drying treatment to be a third set value less than a specified value.
