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, will be described. The structure of the discharge port of is not limited to this and 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, it is preferable that the inner cover 3a that can be opened and closed closely on the upper portion of the inner tank 5, and the tip of the circulation duct 40 is connected to the inner cover 3a. The reason for installing the inner cover 3a is to prevent leakage of heated air during drying of laundry.

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.

On the other hand, in order to facilitate drying, it is preferable to discharge the humidified steam formed in the upper part 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 connection duct 60 is preferably provided between the lower end of the circulation duct 30 and the drain duct 11.

Referring to the operation of the dry washing machine as 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 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 tank 5 is 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 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.

The air introduced into the circulation duct 20 moves upward and exchanges heat with outside air supplied from the first outdoor 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 6 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.

On the other hand, in the above-described structure, the heated air discharged from the tip of the circulation duct 20, that is, the discharge port 20a, is concentrated in the localized portion. This is because the discharge port 20a of the circulation duct 20 is directed in a predetermined direction, that is, in a substantially vertical direction. When the discharge direction of the heated air is fixed in one direction, the heated air is not evenly transmitted to the laundry, and there is a concern that the drying performance may be reduced. In addition, the laundry located in the discharge direction of the heated air may be damaged by heat.

Therefore, in order to improve drying performance and prevent damage to laundry, it is preferable to change the structure of the discharge port 20a suitably.

Referring to Figure 2, when explaining the structure of the discharge port for a dry washing machine according to the present invention.

The tip of the circulation duct 20, that is, the discharge port 20a, is formed to be inclined at a predetermined angle in the direction of the center of the inner tank 5. Here, the inclination angle and the inclination direction are not limited, and may be determined by determining a direction in which the heated air is to be discharged. In addition, as shown in FIG. 3, it is preferable that the discharge port 20a is comprised in substantially elliptical shape. When configured as described above, it is possible to adjust the injection direction of the heated air by appropriately adjusting the angle of the discharge port (20a).

On the other hand, as shown in Fig. 2, when inclining the discharge port (20a), it is preferable in terms of production to protrude the tip of the circulation duct 20 a predetermined length. Of course, it is also possible to give the inner cover 3a a predetermined thickness without protruding the discharge port 20a and to have the shape of the flow path formed in the inner cover 3a at a predetermined angle.

Referring to Figures 4 to 6, another embodiment of the structure of the discharge port for a dry washing machine according to the present invention will be described.

In the above-described embodiment, the direction of the heated air can be adjusted, but the direction of the heated air is fixed. Accordingly, the present invention provides a structure capable of evenly spraying the laundry of the heated air without fixing the direction of the heated air. That is, the wind direction adjusting means 200 is installed in the discharge port 20a.

Preferably, the guide plate 202 has a thin plate shape, and hinge shafts 204 rotatably installed on the inner wall of the discharge port 20a are formed at both sides. In addition, it is preferable that the connecting member 206 for connecting the plurality of guide plates 202 to each other is installed. This is convenient because the angle of the plurality of guide plates 202 can be adjusted at once by moving the connecting member 206.

When configured as described above, the user can adjust the injection direction of the heated air by adjusting the guide plate 202 to a desired angle.

On the other hand, as shown in Figure 6, by connecting an actuator 208, such as a motor, to the guide plate 202, and control the actuator 208 using a controller (not shown), the guide plate 202 is automatically It is also possible to change the direction of injection of the continuously heated air by rotating rotation.

In this embodiment, the wind direction adjusting means 200 is shown and described that is mounted to the discharge port (20a), but the present invention is not limited thereto. That is, the wind direction adjusting means 200 may be installed on the inner cover 3a.

In the above-described embodiment, the structure of the discharge port 20a of the circulation duct 20 for circulating the heated air is illustrated and described, but the present invention is not limited thereto. That is, the structure of the discharge port 20a according to the present invention can be applied to all kinds of blowing ducts for discharging heated air.

In addition, the above-described structure of the discharge port is suitable for a pulsator type dry washing machine, but is not limited thereto, and of course, may be applied to a drum type dry washing machine or the like.

The effect of the structure of the discharge port for a dry washing machine according to the present invention described above is as follows.

According to the present invention, since the heated air can be sprayed evenly to the laundry, the drying performance can be improved. In addition, there is an advantage that it is possible to prevent the local concentrated discharge of the heated air to prevent damage to the laundry by heat.
