On the other hand, Figure 5 shows another embodiment of the present invention, a sectional view showing a general pulsator type washing machine having an inflating device.

First, before explaining the inflator of the present invention, with reference to Figure 1, the pulsator type dry washing machine according to the present invention will be described as follows. First of all, the components for the laundry function of 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 40 is rotatably installed in the inside of (5). Then, the inner tank 5 and the pulsator 40 are rotated by the drive motor 9 provided on the bottom surface 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, will be described. The inflator of is not limited to this and is applicable.

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 20 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.

In addition, it is preferable that a connection duct 60 is further 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.

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 to the upper portion of the inner tank 5 during washing is discharged to the outside through the connection duct 60 and the drain duct 11.

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. At this time, the humid air is circulated through the circulation duct (20).

That is, the air introduced into the circulation duct 20 moves upward and exchanges heat with 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.

On the other hand, in the above-described structure, the laundry during washing or drying in the state in which the laundry is agglomerated on the bottom surface of the inner tank by its own load or dried to reduce the washing efficiency or drying efficiency, or there is a fear that the laundry is packed after drying.

Therefore, in order to improve the washing efficiency and drying efficiency without laundering the laundry, it is preferable that a foaming device is provided to continuously release the laundry by applying upward force to the laundry gathered on the bottom surface of the inner tank.

Referring to Figure 2, when described inflating device of a dry washing machine according to the present invention.

Inflating apparatus for a washing machine according to the present invention, as shown in Figure 1 and 2, is provided in the inner tank (5) and axially coupled to the drive motor (9), selectively rotated by the drive motor A drive pulsator 41 which performs an exercise; A driven pulsator 42 engaged with the outer circumferential surface of the drive pulsator so as to be movable up and down to perform a rotational movement with the drive pulsator; The upper and lower reversible means 50 are provided between the bottom surface of the driven pulsator 42 and the bottom surface of the inner tub 5 so that the driven pulsator also moves up / down in rotational motion. .

At this time, the upper and lower reversible means 50, as shown in Figure 3, is supported on the inner bottom surface of the inner tank 5 and provided in contact with one side of the bottom surface of the driven pulsator 42 and predetermined When the driven pulsator 42 is rotated left / right (see dashed arrow), it rotates up and down (see solid arrow) as it is, and the other side of the driven pulsator (load of laundry) A roller member 51 for applying an impact such that the inclined side is moved up / down; One end is fixed to the bottom surface of the inner tank (5) and the other end is hinged to the rotation center of the roller member 51, the impact applied to the roller member 51 and the driven pulsator 42 is small It is made of an elastic support member 52 for elastically supporting the roller member so as to be absorbed quantitatively, and reversible up / down movement to the driven pulsator by the restoring force at the moment when the other side of the driven pulsator passes the roller member. This is preferred.

In addition, as shown in FIGS. 1 and 3, laundry is prevented from being caught between the outer circumferential surface of the driving pulsator 41 and the inner circumferential surface of the driven pulsator 42, and the upper and lower parts of the driven pulsator In order not to disturb the movement, it is preferable that a flexible gasket 43 is further installed between the outer circumference of the drive pulsator 41 and the inner circumference of the driven pulsator 42.

In addition, as shown in Figure 4, the inner surface of the driven pulsator 42 and the inner tank 5 when the driven pulsator 42 moves up / down about the driving pulsator (41). The driven pulsator of the inner surface of the inner tank 5, in order to maintain the predetermined distance at all times and to cause the laundry located on the outer circumferential side of the driven pulsator 42 to bounce up to the center side of the inner tank 5. It is preferable that the surface of the range in which the outer circumferential surface of the surface be moved up and down is convex outwardly (see section 5b).

Hereinafter, referring to Figures 1 and 4, the operation of the inflator of the pulsator type dry washing machine according to the present invention will be described.

At the time of washing (a macroscopic step including a washing step in which laundry is washed by a detergent and a friction action, and a rinsing step of rinsing the detergent) or drying, the driving pulsator 41 is rotated by the left / right rotation of the driving motor 9. Is rotated left / right, and at the same time, the driven pulsator 42 is also rotated left / right. At this time, by the up / down reversible means 50 supporting the bottom of the driven pulsator 42 on one side, the driven pulsator performs the up / down movement (similar to the conical mode movement.) To lift the laundry (4) seated on.

Meanwhile, referring to FIG. 4, the up / down movement of the driven pulsator will be described in detail.

First, the laundry 4 is seated on the flat portion of the driven pulsator 42, and the roller member 51, which is a constituent element of the upper and lower reversible means 50, is installed on one side of the bottom of the driven pulsator. Since the roller member is supported by the elastic support member 52, although not shown in FIG. 4, the driven pulsator is driven by the load of the driven pulsator 42 itself and the load of the laundry 4. The other side of the driven pulsator to which the load of the laundry is applied based on one side of the data (roller member side) is inclined downward. In addition, when the driven pulsator 42 is applied with the rotational force, the roller member 51 in contact with the bottom surface of the driven pulsator is rotated up and down by the rotational force of the driven pulsator, the other side of the driven pulsator ( The side to which the load of the laundry is applied is smoothly moved to the roller member 51 side.

Thereafter, as shown in FIG. 4, the moment when the other side of the driven pulsator 42 reaches the roller member 51 side, the driven pulsator having left / bypass power (see dotted arrow) and concentrated load of laundry ( The other side of 42 is pressed against the elastic support member 52 by inertia (see arrow; i.e., the other side of the driven pulsator is in a lower position than the roller member, and left / bypassed while being continuously pressed by the load of the laundry). As the power is rotated, the elastic support member for elastically supporting the roller member is pressed at the moment of reaching the roll member.) And at the same time, it is first bounced by the height difference with the roller member 51.

Then, when the other side of the driven pulsator 42 leaves the roller member 51, the force (the force acting on the roller member by the left / bypass power and the concentrated load of the laundry) is pressed against the elastic support member 52. At the same time, the elastic support member 52 is inflated by the restoring force, and the other side of the driven pulsator 42 is bounced secondarily. Eventually, the laundry 4 located on the driven pulsator will spring up.

This phenomenon is similar to a vehicle's wheel bouncing when the vehicle runs on a dirt road.

Meanwhile, the reason why the elastic support member 52 is further added without using only the roller member 51 is that, as described above, when the other side of the driven pulsator 42 and the roller member 51 collide with each other, a great shock occurs. This is because the driven pulsator and the roller may be broken.

And the laundry is thrown out to the upper center side of the inner tank by the inner surface (refer to section 5b of FIG. 4) of the inner tank 5 which made outwardly convex round shape.

After all, the laundry does not agglomerate at the time of washing, so the contaminants on the laundry are decomposed effectively, and the washing efficiency is improved, and when rinsing, the detergent on the laundry is rinsed effectively. The drying efficiency is improved without being lost.

On the other hand, the above-described bubble device is not limited to the pulsator type dry washing machine, it will be obvious that the general pulsator type washing machine without a drying function.

That is, as shown in Figure 5, the general pulsator type washing machine for washing machine is the same structure except for the component to perform the drying function in the above-described structure, specifically, the rotation in the outer tank (3) A washing machine including an inner tank (5) possibly supported and a driving motor (9) provided on a bottom surface of the outer tank to selectively rotate the inner tank; A drive pulsator (41) provided in the inner tank and axially coupled to the drive motor to selectively rotate by the drive motor; A driven pulsator 42 engaged with the outer circumferential surface of the drive pulsator so as to be movable up and down to perform a rotational movement with the drive pulsator; An upper / low reversible means 50 may be provided between the bottom surface of the driven pulsator and the bottom surface of the inner tank to allow the driven pulsator to move up / down in parallel during rotational movement.

In addition, the operation of the nesting apparatus applied to the general pulsator-type washing machine is the same as the operation of the nesting apparatus applied to the pulsator-type dry washing machine described above will be omitted.

So far, the present invention has been described with reference to the preferred embodiments, and those skilled in the art to which the present invention pertains to the detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. Could be implemented. Here, the essential technical scope of the present invention is shown in the claims, and all differences within the equivalent range will be construed as being included in the present invention.
