Agitator type washing machine having drying function}

The present invention relates to a washing machine, and more particularly, to an agitator 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 this is done washing.

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 out the laundry from 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 a dryer makes 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, the development of an agitator type washing machine capable of drying the laundry while having good washing ability has been required.

In order to solve the above problems, it is an object of the present invention to provide an agitator type dry washing machine having a good washing function and drying the laundry.

In addition, it is preferable that an inner tank supply pipe for directly supplying heated air to the inner tank is formed at the tip of the circulation duct.

Therefore, according to the present invention, it is possible to dry directly in the washing machine without moving the laundry after washing.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the agitator dry washing machine according to the present invention will be described.

Referring to Figure 1, when described the agitator 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 inside 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. In the inside of (5), the agitator 7 is rotatably installed. In addition, the inner tank 5 and the agitator 7 are rotated by the driving means 9 installed on the bottom surface of the outer tank 3. At this time, the agitator 7 is a kind of empty hollow of the lower surface. As a hollow structure, a plurality of injection holes 7a are formed in the outer wall.

On the other hand, the upper part of the case 1 is provided with a water supply valve 10 for supplying water for washing and rinsing, the water supply valve 10 is a water supply duct (not shown) for supplying water to the inner tank (5) 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. .

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

A circulation duct 20 is provided between the outer tub 3 and the case to supply heated air for drying the laundry in the inner tub 5. That is, the lower end of the circulation duct 20 is connected to the outer tank 3, the upper end is located near the upper portion of the inner tank (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 inner end of the circulation duct 20 is connected to the inner tank supply pipe 20a for directly supplying the heating air to the inner tank (5). Furthermore, the tip of the circulation duct 20 is branched to further form an agitator supply pipe 20b for supplying heating air to the agitator 7, and the agitator supply pipe 20b and the agitator 7 are further formed. The connection pipe 30 is installed between the, and the agitator (7) is preferably formed with injection holes (7a) for discharging the supplied heated air.

The upper end of the connection pipe 30 is rotatably coupled to the circulation duct 20, and the lower end of the connection pipe 30 is fixed to the agitator 7. This is because, in this configuration, the connecting tube 30 can also rotate with the agitator 7 when the agitator 7 rotates in the washing process or the drying process. Of course, the connecting pipe 30 is constructed in a bellows shape, which is a stretchable structure, and is detachably coupled to the agitator 7 to be separated in the washing process and coupled in the drying process.

As described above, the reason for providing the inner tank supply pipe 20a and the agitator supply pipe 20b is as follows. After the final stage of the washing process, that is, the dehydration stroke, the laundry is between the agitator 7 and the inner wall of the inner tank 5. Therefore, when heated air is simultaneously supplied to the inner tank 5 and the agitator 7, the laundry can be dried uniformly and quickly.

On the other hand, the air discharged from the discharge port of the circulation duct 20 to dry the clothes in the inner tank 5, and the air discharged to the circulation duct 20 again is humid. Therefore, when the humid air is circulated in such a state, the drying efficiency is lowered. Therefore, the moisture contained in the air must be removed during the circulation of the air. Therefore, it is desirable to install an appropriate dehumidifier in order to condense and remove moisture.

Referring to the operation of the agitator type washing machine according to the present invention described above are as follows.

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 drying process begins when washing and dehydration are complete. When the drying process is started, the blowing fan 22 is operated so that the air inside the inner tank 5 circulates through the circulation duct 20 and is supplied to the inner tank 5 again. At this time, the air is heated by the heater 15 is supplied to the inner tank 5 and the agitator (7). The heated air supplied to the inner tank 5 and the agitator 7 heats the laundry to dry the laundry, thereby lowering the temperature relatively. The relatively low temperature air is heated again by the heater 15 through the circulation duct 20 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.
