Problems solved by technology

[0011] However, since the clothes are always dried at the same temperature in the conventional drying method, since the clothes are dried at a high temperature when the drying process is performed, the clothes may be damaged, and drying the clothes when the clothes are dried at a low temperature may take a long time
[0012] Moreover, since it is not possible to detect when the laundry is completely dried, the drying process may end before drying the laundry, resulting in incomplete drying of the laundry.
Or, the drying process continues even after drying is complete, possibly damaging the laundry
[0013] Therefore, in order to prevent the laundry from being damaged, the conventional drying method dries the laundry at a low temperature, and as a result, it takes a long time to dry the laundry
Also, the laundry may not be completely dried so that the drying efficiency decreases

[0073] Figure 4 is a flowchart illustrating a drying process of the drum type washing machine according to the first preferred embodiment of the present invention, and Figure 5 and Figure 6 is instantiated Figure 4 The flow chart of each drying process in .

[0074] The drying method of the drum type washing machine according to the first preferred embodiment of the present invention is a method of not applying heat to the clothes when the drum motor 140 is driven in the first motor driving range, Heat is applied to the laundry while the drum motor 140 is driven in the second motor driving range. Such as Figure 4 As shown, the user first selects the drying mode through the input part 170 (S710), and selects the full drying mode among the drying modes, and then measures the eccentricity (S720).

[0075] There are several ways to measure eccentricity, one way is to estimate the duty of the pulse width modulation (PWM) control signal, and the other way is to measure the...

[0138] Below, will refer to Figure 13 A drying method according to a third preferred embodiment of the present invention will be described.

[0139] Figure 13 is a flowchart illustrating a drying process of the drum type washing machine according to the third preferred embodiment of the present invention.

[0140]The drying method of the drum type washing machine according to the third preferred embodiment of the present invention is similar to the drying method of the drum type washing machine according to the second preferred embodiment of the present invention. However, the drying method according to the third preferred embodiment of the present invention relates to the drying method in the case of selecting the timed drying mode, which is different from selecting the full drying mode when the user selects the drying mode in the first preferred embodiment of the present invention. The case of drying mode.

[0141] Therefore, the same aspects as the second preferred emb...

Abstract

The present invention is designed to reduce time for drying laundry in a drum type washing machine. The drum type washing machine includes a tub including a drum accommodating laundry, a drum motor rotating the drum, a drying duct communicated with the tub to provide a path through which air heated by a drying heater flows, a blower supplying air to the tub through the drying duct, a first temperature sensor for detecting temperature of air, and a microcomputer for controlling a drying cycle. The microcomputer divides the temperature of air in the tub during a drying cycle into first and second temperature ranges, and maintains the air temperature within the first and second temperature ranges by controlling the drying heater during drying processes corresponding to the first and second temperature ranges, and controlling RPM of the drum motor, when the first temperature sensor detects temperature of the drying duct.

Description

technical field [0001] The present invention relates to a drum type washing machine, and in particular to a drum type washing machine for drying clothes in a short time and a drying method thereof. Background technique [0002] Generally, a drum type washing machine is designed in such a form that a cylindrical drum in a washing tub is rotated to drop laundry from an upper portion of the drum to a lower portion of the drum to wash the laundry in a rotation process of the drum. [0003] The drum type washing machine has such characteristics that the damage to the clothes caused by the entanglement of the clothes is relatively smaller than that of the pulsator type washing machine and the agitation type washing machine and that the amount of washing water used for washing the clothes is relatively less than that of the pulsator type washing machine and the agitation type washing machine. . [0004] The drum type washing machine dries thoroughly washed laundry using a dryer in...
