The present invention relates to a manual drying selection control method of a dry washing machine, and more particularly, to detect a quantity of laundry after manually selecting a drying stroke in order to dry a laundry in a drying washing machine equipped with a drying function The drying time is determined differently according to the amount of laundry detected so that it can be dried.

In the conventional washing machine equipped with a drying function, as shown in FIGS. 1 to 3, the washing tank 1 is rotatably installed in the outer tank 4 of the main body 3, and the lower part of the washing tank 1 is provided. Washing wings (5) are installed, the washing tank (1) and the washing blades (5) are fastened through the shaft (7) of the clutch (6) installed in the lower center of the outer tank (4), the outer tank (4) A motor mounted on one side of the lower side and driven by a control signal of a microcomputer (not shown) mounted on the main body 3, wherein the V-belt 8 is wound around the motor 2 and the clutch 6, respectively. The pulley 9 and the clutch pulley 10 are installed.

In addition, on one side of the top cover 11 hinged to the top of the main body 3 so as to be opened and closed, a hot air supply duct 13 having a suction port 12 for suctioning air outside the main body 9 when the laundry is dried is provided. It is installed, the fan 14 in the hot air supply duct 13 is connected to the small motor 15 is driven during drying, the inside of the lower portion of the hot air supply duct 13 inlet ( The heater 16, which is a heating source for making the air supplied through 12) into hot air, is installed, and the other side of the top cover 11 discharges high-temperature, high-humidity moisture evaporated from the laundry during drying out of the main body 3. An outlet 17 for forming is formed.

Therefore, when the user proceeds with washing, washing, rinsing, dehydration and drying process are sequentially performed by the control signal of the microcomputer built in the upper part of the main body 3, and the front cover 11 on the main body 3 When the drying operation is started by pressing the drying selection key 19 of the installed control panel 18, the heater 16 and the hot air supply at the lower end of the hot air supply duct 13 installed on one side inside the top cover 11 on the complement 3 are supplied. The small motor 15, which is connected to the fan 14 in the duct 13 and driven during operation, is operated to rotate the fan 14, so that the air outside the main body 3 is sucked into the hot air supply duct 13. As it passes through the heater 16 is converted into a high temperature hot air flows into the washing tank (1) and at the same time the washing blade (5) in the lower portion of the washing tank (1) is left, right reversed or High speed rotation will be repeated.

At the same time, the moisture contained in the laundry in the washing tank 1 is evaporated by the dried hot air, and at the same time, the high-temperature and high-humidity moisture which is evaporated is discharged through the outlet 17 on the other side of the top cover 11. It is dried for a set drying time, and the drying stroke is completed when the set drying time is completed.

However, the drying efficiency of the laundry is reduced in the conventional drying washing machine because the drying process is performed only for a set drying time without detecting the weight of the laundry or whether the laundry is dry or the dry laundry. There is a lot of problems, such as a significant deviation of the drying, takes a lot of time to use the power consumption of the drying time.

The present invention is to solve the above-mentioned problems, the amount of laundry detected by detecting the amount of laundry after detecting the presence of washing water when manually selecting the drying stroke to dry the laundry in a drying washing machine equipped with a drying function Manual drying of the washing machine, which can reduce the drying variation of the laundry, greatly improves the drying efficiency by allowing the drying time to be determined and dried differently, and can greatly reduce the drying time. The purpose is to provide a selection control method.

In order to achieve the above object, the present invention detects the presence or absence of the washing water in the washing tank during the drying stroke of the laundry, and if the washing water in the washing tank detects the amount of laundry after completing the drainage and dehydration stroke If there is no wash water, the method of manually drying selection control of the dry washing machine to promptly perform a step of detecting the amount of laundry immediately, and differently performing the drying time set according to the detected amount of laundry and then completing the entire drying stroke to be.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 4.

Figure 4 is a flow chart showing the operation state when the drying process of the laundry selection according to the present invention, when the user manually selects the drying function to dry the laundry in the dry washing machine first of the washing tank (1) If there is washing water after detecting whether there is washing water, the draining and dehydration stroke is sequentially completed, and then the drying stroke is performed. If there is no washing water in the washing tank 1, the drying stroke is immediately performed. In addition, after determining whether or not the washing water in the washing tank (1) proceeds to the next program.

First, by detecting the amount of laundry put into the washing tank (1), if there is a lot of laundry, the drying time is carried out for T1 hours, if the amount of laundry is medium, the drying time is carried out for T2 hours, the amount of laundry In this case, the drying time is performed for T3 hours, where the setting condition of the drying time is T1T2T3, and the amount of laundry may be divided into large, medium, and small, and the division of the divided area may be large or small depending on the capacity of the washing machine. You can also explain.

In addition, when the user proceeds to the drying process after washing the hands, the user detects that the amount of laundry is large and performs the drying time for T1 hours. When the drying time (T1, T2, T3) is completed, the entire drying administration is completed. You can complete it.

That is, in the present invention, when the user manually selects and uses only the drying stroke, the user first determines whether the washing water is present in the washing tank 1 or not, and then detects the amount of the laundry, and determines the drying time according to the amount of the laundry. By performing T2, T3) differently, it is possible to greatly reduce the drying variation of laundry, thereby greatly increasing the drying efficiency, and shortening the drying time, thereby reducing power consumption.

Meanwhile, another embodiment of the present invention will be described in detail with reference to FIGS. 5 and 6 of the accompanying drawings.

FIG. 5 is a flowchart illustrating another embodiment of the present invention, and FIG. 6 is a graph diagram showing the correlation between the amount of laundry and the drying time according to the rotational speed of the motor in FIG. 5. When the drying function is manually selected and used to dry the water, the presence or absence of the washing water is first detected in the washing tank (1). If there is no wash water in (1), the drying administration is immediately proceeded. The drying process determines whether the wash water is present in the washing tank 1 as described above, and then proceeds to the next program.

First, the motor 2 is turned on for a predetermined time and then turned off. In this case, when the rotation speed of the motor 2 is a section, it is determined that the amount of laundry put into the washing tank 1 is large and the drying time is T1 time. If the rotation speed of the motor 2 is b section, the drying time is carried out for T2 time, and if the rotation speed of the motor 2 is c section, the drying time is performed for T3 time and then the drying stroke To complete.

That is, the principle of detecting the amount of laundry by the rotational speed of the motor (2) described above is the force F in the formula F = ma (F: force, m: mass, a: acceleration), because the force F uses the same motor (2) Assuming that this is the same, when the laundry in the washing tank 1 is m, the more the laundry, the more the acceleration a is lowered, so that the amount of the laundry can be determined as the rotational speed of the motor 2 during drying.

As described above, the present invention detects the presence of the washing water in the washing tank (1) when the drying stroke is manually selected to dry the laundry in the drying washing machine and then dry by the amount of laundry detected by detecting the amount of laundry By drying differently by drying the time, the drying efficiency can be greatly reduced by reducing the drying variation of the laundry, and the drying time can be greatly shortened, so that the user can use it conveniently and reduce the power consumption. It is a very useful method with advantages.
