Pulsator type washing machine having drying function}

The present invention relates to a washing machine, and more particularly, to a pulsator type washing machine having a washing function and a drying function.

A washing machine is a device that peels contaminants by applying energy such as impact to laundry, and may be divided into a pulsator type washing machine, a drum type washing machine, and an agitator type washing machine according to a method of applying energy to laundry. That is, the laundry is impacted by a pulsator or agitator, or the laundry is dropped by dropping the laundry by the rotation of the drum to wash the laundry. And the action of the detergent is added to the laundry is made.

The above-mentioned washing machines generally have only a function of washing laundry such as clothes. Therefore, the user of the washing machine should take the laundry out of the washing machine after the washing is completed and dry it in the sun.

In recent years, it has been required to be able to artificially dry laundry which has been widely washed in the apartments in a short time due to the widespread use of apartments and changes in living patterns, and a dryer has been developed in response to this demand. The development of the dryer has made it possible to dry laundry which has been washed in a washing machine simply and quickly.

However, in general, a dryer is almost the same size as a washing machine, and therefore, it takes up a lot of space to install each of the washing machine and the dryer, and it is inconvenient to use the laundry having to be removed from the washing machine and put back into the dryer.

Therefore, the development of a washing machine having a drying function has been required. Accordingly, in the drum type washing machine, a washing machine having a drying function capable of being dried directly from a drum without moving laundry after completion of washing has been proposed. In general, however, the washing machine of the pulsator type or agitator type washing machine having a better washing capacity than the drum type has no drying function. Therefore, there has been a demand for the development of a pulsator type washing machine having good washing ability and capable of drying laundry.

In order to solve the above problems, it is an object of the present invention to provide a pulsator-type dry washing machine that has a good washing function and is capable of drying laundry.

In addition, another object of the present invention is to block the lint of the laundry generated during drying to flow back into the inner tank.

Do.

In addition, the upper end of the exhaust duct 40 is preferably connected to the inner cover (3a), the lower end is preferably connected to the rear end of the drain duct 11 (rear end of the portion where the drain valve is installed). Because the drain valve 13 is normally closed during the drying process, the exhaust duct 40 is connected to the rear end of the portion where the drain valve 13 is installed so that the humid air is discharged to the outside.

On the other hand, it is preferable that the inner cover 3a that can be opened and closed on the upper part of the outer tub 5 is tightly installed, and the inner door (not shown) that can be opened and closed on the opening of the inner cover is tightly installed. The reason for installing the inner cover 3a is to prevent leakage of heated air during drying of laundry.

On the other hand, in order to block the lint of the laundry generated during drying back into the inner tank (5), it is preferable that the collecting means 100 for collecting the lint is installed at a predetermined position of the circulation duct (20).

Here, the collecting means 100, as shown in Fig. 2 or 3, is installed so that the filter case 110 is in communication with the portion located in the upper side of the outer tank 3 of the circulation duct 20, Preferably, the filter case 120 is provided to be pulled out of the filter case. Here, the reason for installing the filter case 110 to be located on the upper side of the outer tub 3 is because the user can easily pull out the filter 120.

In addition, the blower fan 22 has a rear end of the filter case 110 (air flowing through the circulation duct so that the circulating air flows into the blower fan 22 after the lint is filtered by the filter 120). It is preferably installed at the rear part passing through the filter.

As shown in FIG. 3, the inside of the filter case 110 is preferably made of a spiral structure, and the filter 120 preferably has a band shape so that the filter case is drawn along the spiral shape. .

Do.

And, as shown in Figure 4, the band-shaped filter sheet 122 is made of a flexible material on the edge of the filter sheet 122 so that it is drawn out smoothly to the filter case 110 along the spiral shape It is preferable that the boundary holder 123 is further mounted.

In addition, as shown in Figure 2, the front of the filter case 110, it is preferable that a straight slot 111 is inserted into which the band-shaped filter sheet 122 is introduced, and, as shown in Figure 4 As described above, in order to block the flow air of the circulation duct 20 from leaking between the door bracket 121 and the filter case 110 after the filter is introduced, a sealer is formed on a surface of the door bracket 121 corresponding to the filter case. 124 is further provided. Although not shown, in another embodiment, a sealer may be provided at the front of the filter case corresponding to the door bracket.

And, as shown in Figure 4, the filter sheet 22, in order to effectively collect the lint, the mesh size of both sides (mesh) based on the center may be made different.

Hereinafter, the operation of the pulsator type dry washing machine according to the present invention will be described with reference to FIGS. 1 to 4.

First, the washing function will be described as follows. The washing function is substantially the same as the operation of a conventional washing machine. That is, the washing stroke, the rinsing stroke and the dehydrating stroke are sequentially performed to wash the laundry. The washing water overflowing the upper portion of the inner tank 5 at the time of washing is discharged to the outside through the exhaust duct 40.

The drying process begins when washing and dehydration are complete. When the drying process starts, the outside air is sucked by the first outside air fan 32, and the sucked outside air is supplied to the circulation duct 20 through the first outside air duct 30. Of course, the air inside the inner tank 5 is also supplied to the circulation duct (20).

The outside air introduced into the circulation duct 20 flows upward by the blowing fan 22 and is heated by the heater 15 to be supplied to the inner tank 5. Heated air supplied to the inner tank (5) heats the laundry to dry the laundry, the temperature is relatively low and the humidity is increased.

Part of the humid air circulates through the circulation duct 20, and part of the humid air is discharged to the outside through the exhaust duct 40. At this time, the humid air formed in the upper portion of the inner tank 5 is mainly discharged to the outside through the exhaust duct 40, the air in the lower portion is circulated through the circulation duct 20.

At this time, as the laundry in the inner tank 5 is dried, the lint separated from the laundry flows with the air to flow into the circulation duct 20. And lint out of the lint-containing air introduced into the circulation duct is filtered by the filter 120. At the same time, the air introduced into the circulation duct 20 is moved upward to exchange heat with the air supplied from the first external air duct 30 to remove moisture. Water dehumidified in the circulation duct 20, that is, condensate is discharged to the outside of the washing machine via the connection duct 60 and the drain duct 11 at the lower portion of the circulation duct 20.

In addition, the lint is removed by the filter 120 and the air having a relatively low temperature and humidity by the first outdoor air duct 30 passes through the blower fan 22 and is heated by the heater 15 again to form an inner tank 5. Is supplied.

As described above, the heated air circulates the inner tank 5 to dry the laundry in the inner tank 5, and the drying process is completed after a predetermined time cycle.

On the other hand, when the number of drying times increases, when it is time to clean the filter 120, the user pulls the door bracket 121 to remove the filter from the filter case 110, and then cleans the filter sheet 122 again to clean the filter case Just insert the filter into.
