Description

Device for drying the laundry in washing machine

The present invention relates to a washing machine, and more particularly, in a drying apparatus of a washing machine for supplying warm air to a laundry to which washing is completed, drying the washing machine to obtain a wrinkle-free laundry by drying the laundry in a separate space outside the washing tank. Relates to a device.

In general, a washing machine is a product that removes various contaminants attached to clothes, bedding, etc. by using the emulsification of the detergent, the friction action of the water flow due to the rotation of the pulsator, and the impact action of the pulsator on the laundry. The fully automatic washing machine automatically performs a series of processes leading to washing, rinsing, and dehydration without user intervention in the middle.

Such a washing machine may be roughly classified into a top loading method in which the washing tank is standing and a drum washing machine in which the washing tank is laid, depending on the type of the washing tank in which the laundry is accommodated. Among them, the top-loading washing machine has a method of washing by left and right stirring of the pulsator and a method of washing by centrifugal force generated while the washing tank rotates, and the structure of the electronic pulsator washing machine Same as

As shown in FIG. 1, the pulsator type washing machine is elastically supported by a plurality of suspension devices in the main body 1 and is provided with a reservoir 2 for storing wash water and rotatably inside the reservoir. Washing tank (3) for accommodating laundry, and a pulsator (4) is installed at the lower end of the washing tank to generate water flow while stirring left and right, and is provided on one side of the bottom of the water storage tank to generate the rotational force of the washing tank and pulsator It consists largely of the motor 5 and the clutch 7 which selectively transmits the power of the said motor to a washing tank and a pulsator.

At this time, in order to transmit the power of the motor 5 to the washing tank 3 and the pulsator 4, pulleys 8a and 8b are provided at the shaft end and the clutch of the motor, respectively, and between the pulleys, V-belts. 8c is provided. In addition, a washing shaft 6a for transmitting power of the motor 5 to the pulsator 4 is provided above the pulley 8b of the clutch, and the motor 5 is a hollow tube surrounding the outer circumference of the washing shaft. Dehydration shaft (6b) for transmitting the power of the washing tank 3 is provided.

Referring to the washing and dehydration process of the pulsator type washing machine configured as described above are as follows.

First, when power is applied to the motor 5 and rotates at the time of washing, the rotational force generated by the motor is transmitted to the clutch 7 through the motor pulley 8a and the clutch pulley 8b. By the operation of the rotational force of the motor is transmitted only to the washing shaft (6a). At this time, the rotational force transmitted to the washing shaft (6a) is moderately decelerated through a reducer (not shown) to generate water flow in the washing tank (3) while stirring the pulsator (4) from side to side to perform washing.

Next, at the time of dehydration, the drain valve 9a is opened and at the same time, the dehydration shaft 6b is constrained to the washing shaft 6a by the operation of the clutch 7 so that the rotational force of the motor 5 is simultaneously transmitted to the washing shaft and the dehydration shaft. do. At this time, the rotational force of the washing shaft 6a is transmitted to the pulsator 4 as it is without deceleration, and the washing tank 3 and the pulsator are dehydrated by rotating at high speed in one direction.

On the other hand, most of the water contained in the laundry during the dehydration administration is removed, but considering the structural limitations and damage problems of the laundry to produce centrifugal force, the drying of the laundry was bound to some extent. Therefore, recently appeared washing machines are further provided with a separate device for drying the laundry after the dehydration administration is completed. The drying apparatus of such a washing machine is roughly classified into an exhaust type and a circulation type according to a drying method. Among these, the configuration of the exhaust type drying apparatus is schematically described as follows.

As illustrated in FIG. 1, a warm air duct 10 is provided at one side of the upper portion of the main body 1 to communicate with the outside to inject external air into the washing tank 3, and the laundry in the washing tank is disposed at one side of the water storage tank 2. Exhaust duct 20 through which the humidified air is discharged to the outside is provided. At this time, the hot air duct 10 is provided with a blowing fan 11 for forcibly injecting external air into the washing tank 3, and a heater 12 for forcibly warming the air supplied by the blowing fan. .

The drying apparatus configured as described above is supplied with power to the blower fan 11 and the heater 12 after the dehydration stroke is completed, and the high-temperature dry external air is introduced into the upper portion of the washing tank 3 through the hot air duct 10. Thus, while the laundry in the washing tank is dried, the humidified air is completely discharged to the outside through the exhaust duct 20 to completely remove the moisture of the laundry. At this time, as the pulsator 4 in the washing tank stirs the laundry evenly while turning left and right, the drying effect can be further increased.

On the other hand, the circulation drying apparatus also has the same function as the above-described exhaust type drying apparatus in addition to circulating high temperature and high humidity air through a separate dehumidifying apparatus.

However, the drying apparatus of the washing machine as described above has the following problems.

First, the conventional drying apparatus, regardless of the amount of the laundry is large and small, as the drying is performed while mixing the laundry using a rotation in the washing tank, the wrinkle phenomenon of the laundry is indispensably caused. This is due to the fact that the conventional drying apparatus imposes importance only on the capacity side and the drying time, rather than the quality of the laundry. In this way, a lot of wrinkled laundry can be worn or used only after ironing again. Thus, the user had to take the hassle of recleaning the laundry even if the drying administration was completed.

Second, in the conventional drying apparatus, as the drying administration proceeds in a state in which laundry is accommodated in the washing tank, variation in dryness according to the laundry occurs severely. This phenomenon was more severe the greater the amount of laundry. In this case, even if the drying administration is completed, the laundry that is not properly supplied with hot air is kept wet.

The present invention has been made to solve the above problems, an object of the present invention is to provide a drying device to supply a warm air to the laundry to be washed in the drying apparatus of the washing machine, by drying the laundry in a separate space other than the washing tank to clean the laundry At the same time to provide a drying apparatus of the washing machine to be able to dry all the laundry evenly.
