Description

Drying method of washing machine

The present invention relates to a drying method of a washing machine, and in particular, in the case of drying a laundry by a heater heat after a series of washing operations are completed, whether the laundry to be dried is placed in the washing tank by sensing a load by a pulsator during drying of the laundry. The present invention relates to a drying method of a drying machine, which determines whether or not it is spread over a drying table and performs drying in a pulsator driving or stopping state according to a sensing state thereof.

Generally, when a washing machine, washing, rinsing, and dehydration, which is a series of washing operations, is completed, if a user selects a drying mode, the dry washing machine drives the heater mounted on the washing tank to blow heat from the heater to dry it. do.

In the case of the conventional dry washing machine, in drying the dehydrated laundry, by drying the laundry to be dried using a drying rack such as a hanger or by rotating the pulsator in a state in which the laundry is left inside the washing tank without using the drying rack. Mix the laundry to be dried as you dry.

In the conventional dry washing machine, the pulsator is also driven to dry during drying, so there is no problem when the laundry is dried using a pulsator, but when the laundry is dried using a drying rack, the pulsator is used. Although not required to drive, the pulsator is designed to be driven, which not only wastes unnecessary power due to pulsator driving but also causes noise.

An object of the present invention is to detect the load state of the dry drying after a series of washing administration to selectively turn on and off the operation of the pulsator in accordance with the detected load state to dry the laundry by drying the laundry to hang The present invention provides a method for drying a washing machine that can reduce power consumption and noise caused by unnecessary operation of the pulsator in accordance with a drying program even when agitating rotation of the pulsator is not required.

The present invention for achieving the above object is a step of determining whether the laundry to be dried in the washing tank or hanging on the drying tank by driving the pulsator in the drying stroke after the dehydration completion according to a series of washing stroke, the laundry in the washing tank When detected by the pulsator driving load, the pulsator is driven to rotate the laundry and dried by applying hot air, and the laundry is placed on the drying rack, and if the load is not detected by the pulsator load, the hot air is applied while drying by stopping the pulsator. And, when the drying time reaches the set time, characterized in that it comprises the step of terminating the hot air drying of the laundry.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a control circuit of a dry washing machine of the present invention.

As referred to herein, the control circuit for the execution of the present invention includes a driving signal input unit (A) for inputting a driving signal for a series of washing administration and the operation signal input from the driving signal input unit (A) A microcomputer (b) for controlling and outputting a signal controlled by a predetermined program, a water supply / driving drive unit (c) for supplying and draining water to a washing tank by the control signal of the microcomputer (b), and the water supply / drainage driving unit (c) Water level detection unit (D) for detecting the water supply and drainage level in the (D), and when the washing water level is completed in the water level detection unit (D), the motor driving unit for washing, rinsing, dehydrating, and driving the drive according to the control signal of the microcomputer (E) and a heater driving unit (bar) for drying the laundry by the heat of the heater after the completion of a series of washing operations by the control signal of the microcomputer (b), and the amount of drying at the time of drying by the control signal of the microcomputer (b). Detect And a load sensing portion (S), and driven by a control signal of the microprocessor (B) is composed of a tuyere ET (H) for blowing a heating column.

2 is a flowchart illustrating a drying process of the dry washing machine of the present invention.

This is, when dehydration is completed in a series of washing strokes and the drying stroke starts, a load sensing step 20 for sensing a load by driving a pulsator and a load for determining whether a load is detected in the load sensing step 20 Detecting step 21 and, if the load is not detected in the load detection step 21, stop the pulsator driving, drying drying step 22 for driving and drying the heater and the blowing fan, and the load sensing judgment When the load is detected in step 21, the pulsator drying step 23 for forward and reverse rotation of the pulsator and driving and drying the heater and the blower fan, and in the drying table drying or pulsator drying steps 22 and 23, respectively. And a drying completion determination step 24 of drying while judging whether the drying is completed.

Referring to the operation of the present invention made as described above are as follows.

First, the washing machine controls water supply and drainage drive (C) in the washing tank before drying and supplies water to the washing tank and detects the water level through the water level detection unit (D). ) To complete the washing by performing a series of washing, rinsing, and dehydrating strokes.

In this way, when a series of washing administration is completed, the microcomputer (b) proceeds with the drying operation by a predetermined program.

When the drying operation is started, the microcomputer (b) goes to the load sensing step (20) to control the motor driving part (e) first and forward and reverse rotation of the pulsator, and also controls the load sensing part (g) to the washing tank. It will detect if there is laundry to be dried on the floor.

At this time, if the wet laundry to be dried is placed on the pulsator in the washing tank as it takes a rotational load during the temporary rotation of the pulsator, it is possible to determine whether the laundry to be dried is placed on the bottom of the washing tank. If the wet laundry to be dried is hung on the dryer's rack, the pulsator will be idle, so it is easy to see that it is no-load.

Accordingly, in the state where the pulsator is rotated forward and reverse, the load of the laundry is sensed and the microcomputer (b) goes to the load sensing step 21 to determine whether the load is detected from the load sensing unit (g). In this case, if the load is not determined as a result of the load determination, the microcomputer (b) determines that the current laundry is dried by using a drying rack, and then goes to the drying rack drying step (22) of the microcomputer (b) to control the motor driving unit (e). The pulsator drive is stopped to control the heater driving part (bar) and the blowing driving part (h) to blow hot air into the dry material to be dried.

However, if the load is detected from the load sensing unit (g) in the load sensing step 21, in the microcomputer (b), the wet laundry in the washing tank to be dried is not dried using a drying rack but is placed in the washing tank as it is. The microcomputer (b) goes to the pulsator drying step (23) to control the motor driving part (e) to control the motor driving part (e), and to rotate the pulsator forward and backward. ) To let hot air blow into the building to dry.

The forward and reverse rotation of the fraudulent pulsator brings back wet laundry evenly, reducing the drying time.

Then go to the drying determination step 24 to determine whether the drying rack drying or pulsator drying is complete and if the drying is not complete at this time is to dry and complete until the drying is complete.

As described above, the present invention detects a load state of a dry product to be dried when dehydration, which is a series of washing operations, is completed, and when a load is sensed, drying with rotating a pulsator and not detecting a load state. By drying the pulsator to stop the rotation is to provide an effect that can solve the cumbersome problem of drying and controlling the pulsator on and off one by one when drying.
