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 that can be dried directly on 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.

Further, another object of the present invention is to improve the performance of the device by allowing the air exhausted from the inner tank to be uniformly exhausted.

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.

A blowing duct for supplying heated air for drying the laundry is connected to the upper part of the outer tub. 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, will be described. The structure of the inner cover 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, the connection duct 60 is preferably installed between the lower end of the circulation duct 20 and the drain duct 11. 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, 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 that can be opened and closed (see 3b in FIGS. 2 and 4) is tightly installed on 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.

And, as shown in Figure 2 to 5, the inner cover (3a) is preferably formed in the flow path portion so that the air of the inner tank is uniformly escaped to the outside. In order to form a flow path part, the inner cover 3a is preferably hollow in shape.

At this time, the flow path portion of the inner cover (3a), a plurality of inlet holes 101 are formed on the bottom surface of the inner cover at the required interval along the periphery so that the humid air of the outer tub 3 is uniformly introduced therein, ; A conduit line (see 102 in FIGS. 1 and 4) is formed inside the inner cover so that the humid air introduced into the inlet hole can flow inside the inner cover; Preferably, the discharge hole 103 is formed on the upper surface of the inner cover so that the humid air flowing along the pipe is discharged to the exhaust duct 40.

In addition, in order to drain the condensed water 110a generated from the humid air flowing through the conduit 102, as shown in FIG. 4, a condensed water outlet 110 is further formed on the outer periphery of the bottom of the inner cover 3a. Preferably, it is formed, and the auxiliary connection duct (see 120 of FIG. 1) further connecting the condensate discharge port and the drainage duct so that the condensate flows into the drainage duct 11 provided at the bottom of the outer tub 3. This is preferred.

On the other hand, the circulation duct is preferably installed through the inner cover (3a) as shown in Figure 5 so that the humid air of the conduit 102 is not mixed with the air of the circulation duct (20).

In addition, the upper surface of the inner cover (3a) is preferably connected to the water supply duct (10a) for supplying the wash water to the outer tub (3).

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

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. During washing, the wash water overflowing to the upper portion of the inner tank 5 is discharged to the outside through the auxiliary connection duct 120 or the exhaust duct 40 through the flow path portion of the inner cover.

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 supplied to the circulation duct 20 flows upward by the blowing fan 22 and is heated by the heater 15 and 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 uniformly introduced into the plurality of inlet holes 101 formed at uniform intervals on the bottom of the inner cover 3a, and then flows through the conduit 102. While being guided to the exhaust duct 40 through one discharge hole 103 formed in the upper surface of the inner cover. It is discharged to the outside through the exhaust duct. At this time, the humid air introduced into the pipe line 102 of the inner cover is dehumidified a predetermined amount during the flow of the pipe, dehumidified water, that is, condensate water passes through the condensate outlet 110 and the auxiliary connection duct 120 and the drain duct 11 ) Is sequentially discharged to the outside of the washing machine.

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.
