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 drying directly from a drum without moving laundry after completion of washing has been proposed. In general, however, a washing machine of a pulsator type or an agitator type which has a better washing capacity than a 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.

Another object of the present invention is to reduce the height difference between the inner door and the inner cover while maintaining airtightness between the inner door and the inner cover.

Referring to Figure 1, it will be described an embodiment of a pulsator type dry washing machine according to the present invention. First, the components for the washing function for washing laundry will be described as follows.

An inner tub 3 for storing the washing water is installed in the washing machine case 1, and an inner tub 5 in which a plurality of through holes 5a are formed is rotatably installed in the tub 3. The pulsator 7 is rotatably installed in the inside of (5). And the inner tank 5 and the pulsator 7 are rotated by the drive means 9 provided in the bottom face of the outer tank 3.

On the other hand, a water supply valve 10 for supplying water for washing and rinsing is installed at an upper portion of the washing machine case 1, and a water supply duct for supplying water to the inner tank 5 is provided in the water supply valve 10. Is connected. A drain duct 11 for discharging the dirty laundry water after the completion of washing to the outside of the washing machine is connected to the bottom of the outer tub 3, and a drain valve 13 is installed at a predetermined position of the drain duct 11. . Unexplained reference numeral 1a denotes a washing machine cover.

Next, the components for drying the laundry will be described.

The inner tank 5 is connected with a blowing duct for supplying heated air for drying the laundry. In the present embodiment, as an example of the blower duct, the blower duct of the circulation duct, that is, a structure in which heated air is circulated back to the inner tank 5 without being discharged to the outside after being heat-exchanged with the laundry, is described. The inner cover and the inner door of the sealing means and is not limited to this can be applied.

In detail, a circulation duct 20 is provided between the upper and lower portions of the outer tub 3 to supply heated air for drying the laundry in the inner tub 5. Of course, a predetermined position of the circulation duct 20 is provided with a heater 15 for heating the air and a blowing fan 22 for forcibly circulating the air.

On the other hand, the first outside air duct 30 for supplying the outside air is connected to a predetermined position of the circulation duct 20, the first outside air fan for generating a suction force for sucking the outside air to the inlet of the first outside air duct ( 32) is preferably installed. Because, drying the clothes in the inner tank (5) and the air discharged back to the circulation duct 20 is a high temperature and high humidity, and when the high temperature and high humidity air circulated in that state, the drying efficiency is lowered, which contains air This is because moisture must be removed. That is, when the outside air is supplied to the circulation duct 20, the relatively low temperature outside air and the high temperature and high humidity circulation air are exchanged to remove moisture.

In addition, it is preferable that a connection duct 60 is further installed between the lower built-in duct 17 and the drain duct 11 corresponding to the other end of the circulation duct 20. The connection duct 60 is a passage through which the water condensed in the circulation duct 20 flows into the drain duct 11.

On the other hand, in order to facilitate drying, it is preferable to discharge the humidified air formed in the upper portion of the inner tank 5 to some extent to the outside. Therefore, for this purpose, the exhaust duct 40 is preferably installed on the upper portion of the outer tub 3. In addition, the exhaust duct 40 also serves to discharge it to the outside when the washing water overflows during the washing process.

In addition, the humid air is not good to be discharged to the outside as it is through the exhaust duct 40, so it is good to discharge the temperature and humidity of the humid air to the outside to some extent. Therefore, it is preferable that a second outside air duct 50 for introducing outside air is connected to a predetermined position of the exhaust duct 40, and a second outside air fan 52 is installed at the inlet of the second outside air duct 50. 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, as shown in Figure 2, it is preferable that the inner cover 3a that can be opened and closed tightly on the upper part of the outer tub 5, and the inner door 3b that can be opened and closed close to the opening of the inner cover. . The reason for installing the inner cover 3a is to prevent leakage of heated air during drying of laundry.

When the inner door 3b is closed, the inner door and the inner cover and the inner cover 3a are maintained so as to maintain the airtightness and at the same time reduce the height difference between the inner door and the inner cover. Preferably, sealing means is provided between the inner covers.

Hereinafter, the sealing means will be described in detail with reference to FIGS. 2 and 3.

The sealer 110 is installed on the bottom of the inner door 3b along its circumference, and the sealer is seated and the lower part of the inner cover 3a is positioned below the upper surface of the inner cover 3a. It is preferable to form the inclined surface 120 inclined in the direction. Here, the height difference between the inner door 3b and the inner cover 3a is changed according to the inclination angle θ of the inclined surface 120.

That is, as the inclination angle θ increases, the sealer 110 is deeply seated on the inclined surface 120, so that the height difference decreases, but it is difficult to maintain airtightness. Since it is properly seated and airtight is maintained but the height difference is not reduced, the inclination angle θ is preferably about 30 degrees to 60 degrees.

In addition, a seating rib 130 may be further formed around the bottom surface of the inner door 3b so that the sealer 110 may be inserted and seated properly.

In addition, it is preferable that the insert portion inserted into the seating rib of the sealer has a wedge shape so that the sealer 110 is easily seated on the seating rib 130 and does not fall out of the seating rib when the door is opened or closed.

On the other hand, when the sealer 110 of the inner door (3b) is closely seated on the inclined surface 120 of the inner cover (3a), the hook 140 is installed on the inner door hook hook 150 of the inner cover The inner door and the inner cover are tightly coupled to each other.

Hereinafter, with reference to Figure 1, the operation of the pulsator type dry washing machine according to the present invention.

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 introduced into the circulation duct.

The outside air supplied to 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).

Then, the air introduced into the circulation duct 20 is moved to the upper side and heat is exchanged with the outside 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. The dehumidified air having relatively low temperature and humidity is again heated by the heater 15 and supplied to the inner tank 5.

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.
