In addition, the present invention may further include an air circulation duct 60 for circulating the air in the clothing accommodating portion. The air circulation duct 60 is provided to circulate some air inside the clothing accommodating part and exhaust some air to the exhaust duct 61 so that the clothes of the circulating clothes processing device and the exhaust clothes processing device are mixed. A processing apparatus can be provided.

Hereinafter, for convenience of description, it will be described on the assumption that the clothes treatment apparatus including the air circulation duct (60).

The air circulation duct 60 may be provided on the upper circumferential surface 230 of the tub as a flow path that draws the air inside the tub 20 to the outside of the tub 20 and guides the tub 20 back to the tub 20.

The tub 20 may be provided with a first communication part 610 and a second communication part 630 to be coupled to the air circulation duct 60.

As shown in FIG. 2, the first communication part 610 is a flow path for guiding air in the air circulation duct 60 to the tub 20, and the second communication part 630 is air in the tub 20. It becomes a flow path which guides to the air circulation duct (60).

The first communication unit 610 may be provided in the gasket 50. That is, the first communication part 610 may be provided as a hole penetrating the gasket 50, and the air outlet of the air circulation duct 60 may be coupled to a hole formed in the gasket 50.

Although the first communication part 610 may be provided on the circumferential surface 230 of the tub like the second communication part 630, when the first communication part 610 is provided in the gasket 50, the air circulation duct 60 is provided. ) Can be supplied to the center of the drum 30 through the drum opening 310 to increase the heat exchange efficiency of the laundry and air.

The heating unit provided to supply the heated air to the tub 20 may be provided as a fan 640 and a heater 670 provided in the air circulation duct 60. The fan 640 not only introduces the air inside the tub 20 into the air circulation duct 60 through the first communication unit 610, but also returns the air introduced into the air circulation duct 60 to the tub 20. It is a means to move. The heater 670 is a means for heating the air introduced from the tub 20 through the second communication unit 630 by the operation of the fan 640.

In this case, the first communication unit 610 and the second communication unit 630 is preferably provided to be positioned in a diagonal direction with respect to the cross section of the tub parallel to the ground on which the cabinet 10 is supported, the heater 670 It may be provided to include a portion extending along the longitudinal direction of the air circulation duct (60). This is to secure a sufficient time for the air moving along the air circulation duct 60 to be heated by lengthening the length of the flow path formed by the air circulation duct 60.

Some of the air supplied to the tub 20 through the air circulation duct 60 is discharged to the outside of the tub 20 through the exhaust duct 61, and into the air circulation duct 60 by the fan 640. Some of the incoming air is supplied from the outside through the intake duct 62 as well as the tub 20.

The intake duct 62 is preferably provided on the flow path through which the air in the tub 20 flows into the fan 640. This does not include a separate air inlet means in the intake duct 62, the air circulation inside the tub 20 and the air outside the tub 20 only by the fan 640 provided in the air circulation passage 60 To flow into the duct 60.

FIG. 2 illustrates an example in which the intake duct 62 introduces air outside the tub 20 into the air circulation duct 60 through the first communication unit 610. In this case, when the fan 640 rotates, a negative pressure is formed in the first communication part 610 so that air inside the tub 20 and air outside the tub 20 flow into the air circulation duct 60. Will be.

On the other hand, the intake duct 62 provided in the present invention does not need any separate control means (valve, etc.) for controlling the opening and closing of the intake duct 62. That is, the intake duct 62 provided in the present invention may be provided to maintain the open state at all times.

As illustrated in FIGS. 1 and 2, the exhaust duct 61 communicates with the tub 20 and the outside of the cabinet 10 to guide the air introduced into the exhaust duct 61 to the outside of the cabinet 10. It may be, but is preferably connected to the drain passage 90 is provided to discharge the wash water in the tub (20).

Since the air discharged through the exhaust duct 61 is a high humidity air, if the exhaust duct 61 is provided to communicate directly with the outside of the cabinet 10, the air discharged from the exhaust duct 61 condenses on the interior wall. This can cause problems.

The clothes treating apparatus 1 of the present invention is provided with a drainage passage 90 for discharging the washing water in the tub 20 to the outside of the cabinet 10, so that the exhaust duct 61 is connected to the drainage passage 90. One problem can be solved.

In this case, the connection point between the exhaust duct 61 and the drain passage 90 is preferably further provided with a flow path switching unit 16 for controlling the opening and closing of the exhaust duct and the drain passage 90. This is to prevent the air discharged through the exhaust duct 61 from being re-introduced into the tub 20 and to prevent the water discharged through the drain passage 90 from being re-introduced into the tub 20.

The flow path switching unit 16 provided at the connection point between the exhaust duct 61 and the drain passage 90 is preferably provided at a position higher than the highest water level set in the tub 20.

When the flow path switching unit 16 is provided at a position higher than the highest water level set in the tub 20 as in the present invention, since the exhaust duct 61 serves to prevent siphon phenomenon, the water trap is switched to the flow path. It is formed between the part 16 and the pump 93 (second drainage flow path) to prevent odors from flowing into the tub 20.

In addition, since the air introduced into the exhaust duct 61 may be discharged to the outside of the tub through the flow path switching unit 17, the rotation speed control of the fan 640 for removing the water trap is unnecessary.

In addition, the above-described structure can prevent the washing water from being discharged to the outside of the tub 2 through the drainage passage 6 even if the washing water is supplied to the highest water level set in the tub 2.

On the other hand, Figures 1 and 2 shows a clothes handling apparatus (1) in which the circulation type and the discharge structure is mixed, but is not limited thereto. Only the circulation type or only the discharge type may be applied.

3 to 6 illustrate one embodiment of the present invention that includes a rib 70 structure that affects a flow path of air flowing out through the first communication part 610. In addition, in order to clearly show the structure of the rib 70, some components of the clothes treating apparatus 1 are omitted or simplified.

3 shows a gasket rib 710. The gasket rib 710 is provided in the gasket 50 and is provided around the first communication part 610 in which the gasket 50 and the air circulation passage 60 communicate with each other. Specifically, the gasket rib 710 is provided between the first communication portion 610 and the tub opening 210.

Assuming that there is no gasket rib 710 in Figure 3, a portion of the air flowing in the direction of the tub opening 210 through the first communication portion 610 is introduced into the drum 30 through the drum opening 310 , Part flows into the space between the tub 20 and the drum 30.

The air introduced into the space between the tub 20 and the drum 30 flows out into the air circulation path 60 through the second communication unit 630 without performing heat exchange (drying) with the laundry inside the drum 30. do. That is, since the heater 670 is heated up to air that is not actually used for drying, energy efficiency is very low.

However, the gasket rib 710 may play a role in which air does not leak into the space between the tub 20 and the drum 30.

As shown in FIG. 3, the gasket rib 710 is provided between the first communicating portion 610 and the tub opening 210, and is provided at an upper periphery of the gasket 50 in which the first communicating portion 610 is located. That is, the air introduced through the first communication unit 610 is primarily blocked by the gasket rib 710 to be spread after a predetermined distance further flows in the direction of the door 40 (ground direction).

Since the gasket rib 710 blocks the space between the tub 20 and the drum 30, more air may flow into the drum opening 310.

Specifically, the gasket rib 710 extends from the gasket 50 in the center direction of the gasket 50 or in the center direction of the tub opening 210. It may be provided extending in a direction parallel to the plane including the tub opening 210.

At this time, the gasket rib 710 is preferably extended to a level that does not contact the drum (30). That is, the gasket rib 710 should not be in contact with the drum opening 310, and it is preferable that the gasket rib 710 is shorter than the shortest distance between the gasket 50 and the drum 30.

If the tub 30 and the gasket 50 come into contact when the drum 30 rotates, the drum 30 may not rotate smoothly. Thus, the length of the gasket rib 710 needs to be adjusted to such an extent that it does not come into contact with the drum 30 as described above.

In addition, a plurality of gasket ribs 710 may be provided along the inner circumferential surface of the gasket 50. Since the gap formed by the tub opening 210 and the drum opening 310 forms a circular ring, a plurality of gasket ribs 710 may also be provided in the gasket 50 along the gap.

In addition, the gasket rib 710 may be provided in a disk shape including an opening along the inner circumferential surface of the gasket 50 in order to prevent the air from leaking through the circular ring gap in more detail. In other words, the gasket rib 110 may be provided in a ring shape. That is, it corresponds to a form in which a plurality of gaskets 50 are continuously connected in the above-mentioned embodiment.

4 corresponds to a view where the tub 720 is provided. The tub 720 is provided on the inner surface of the tub 20. In one embodiment of the present invention, the inner surface of the tub 20 is provided on the inner surface of the tub front surface 220. On the other hand, it may be provided on the inner surface of the tub circumferential surface 230 or the inner surface of the tub opening 210. When provided in the tub opening 210, since it corresponds to a position similar to the gasket rib 710, it is preferably provided on the inner surface of the tub front surface 220.

The tub 720 also serves to prevent the air introduced through the first communication part 610 and the tub opening 210 from being introduced into the space between the tub 20 and the drum 30. That is, it serves to increase the resistance of the air flow path between the tub 20 and the drum 30.

The tub 720 extends toward the outer surface of the drum 30. This is to prevent the space between the drum 30 and the tub 20 through which air passes. The direction in which the tub 720 extends may be directed as long as it faces the drum 30, but in order to reduce the material cost, the tub 720 may reach the drum 30 from the point where the tub 720 starts to reach the drum 30. It is preferred to extend. This is because the space can be blocked with the minimum material.

However, it is preferable that the tub 720 extends toward the outer surface of the drum 30 but does not come into contact with the drum 30. Specifically, the tub 720 preferably maintains a length shorter than the shortest distance between the inner surface of the tub 20 and the drum 30.

The drum 30 rotates irrespective of the tub 20, because when the tub 720 extends to be in contact with the drum 30, the drum 30 is prevented from rotating. In addition, unbalance may occur while the drum 30 rotates, and vibration may occur. Preferably, the length of the tub 720 is adjusted so that the drum 30 does not come into contact with the drum 30 even if the vibration occurs.

On the other hand, the tub 720 may also be provided with a plurality. As a plurality of tubs are provided along the tub front surface 220 or the tub circumferential surface 230, the air flow path resistance between the tub 20 and the drum 30 may be increased. In addition, the plurality of tubs 720 may be continuously connected to increase air flow resistance more densely.

5 illustrates a drum rib 730. The drum rib 730 is provided on the outer surface of the drum 30. In one embodiment of the present invention, the drum rib 730 is provided on the outer surface of the drum front surface 320 of the outer surface of the drum 30. In addition, the drum rib 730 may be provided on the outer surface of the drum circumferential surface 330, may also be provided on the outer surface of the drum opening 310.

The drum rib 730 also serves to prevent the air introduced through the first communication portion 610 and the tub opening 210 from being introduced into the space between the tub 20 and the drum 30. That is, the tub 720 may serve to increase the resistance of the air flow path between the tub 20 and the drum 30.

The drum rib 730 extends toward the inner surface of the tub 30. This is to prevent the space between the drum 30 and the tub 20 through which air passes. The direction in which the drum rib 730 extends may be directed as long as it faces the tub 30, but in order to reduce the material cost, the drum rib 730 extends from the point where the drum rib 730 begins to reach the tub 30. It is preferred to extend. This is because the space can be blocked with the minimum material.

However, the drum rib 730 preferably extends toward the inner surface of the tub 20 so as not to contact the tub 20. Specifically, the drum rib 730 preferably maintains a length shorter than the shortest distance between the outer surface of the drum 30 and the tub 20.

The drum 30 rotates irrespective of the tub 20 because when the drum rib 730 is extended enough to contact the tub 20, the drum 30 is prevented from rotating. In addition, while the drum 30 is rotating, unbalance of laundry may occur inside the drum 30, and vibration may occur. The length of the drum rib 730 is adjusted so that the tub 20 does not come into contact with the tub 20 even when the vibration occurs. It is desirable to.

Meanwhile, a plurality of drum ribs 730 may also be provided. As a plurality of drums are provided along the outer surface of the drum 320 or the drum circumferential surface 330, the resistance of the air flow path between the drum 30 and the tub 20 may be increased. In addition, the plurality of drum ribs 730 may be continuously connected to increase air flow resistance more densely.

FIG. 6 illustrates a gasket rib 710, a tubbri 720, and a drum rib 730. Specifically, the relationship between the tub 720 and the drum rib 730 will be described.

The tub 720 and the drum rib 730 may be provided to cross each other based on the flow of air. In other words, when the tub 720 is provided on the inner side of the front face of the tub 20 and the drum rib 730 is provided on the front face of the drum 30, the tub rib 720 and the drum rib 730 are provided. ) May be provided at different heights. Accordingly, an air flow path, such as a maze, may be formed between the tub 20 and the drum 30.

In addition, it is preferable that the total sum of the lengths of any one tub 720 and one drum rib 730 is longer than the shortest distance between the tub 20 and the drum 30. As can be seen in FIG. 6, the tub 720 and the drum rib 730 overlap with each other based on the direction in which air flows between the tub 20 and the drum 30. In other words, air cannot flow in a straight line in the space between the tub 20 and the drum 30, and the air flow path becomes longer due to the arrangement and the length of the tub 720 and the drum rib 730. Gives birth That is, the air flow path resistance between the tub 20 and the drum 30 becomes very high.

In order to prevent the drum 30 from contacting the tub 20 by vibration generated when the drum 30 is rotated by the driving unit, the length of the tub 720 and the drum rib 730 has been described above. When installed in the tub 20 and the drum 30 by crossing the tub 720 and drum rib 730, respectively, the same effect as when the length of the tub 720 or drum rib 730 is lengthened can be obtained. have.

On the other hand, when all the tub 720, the drum rib 730 and the gasket rib 710 are used, since the air flow path resistance is the maximum, a large number of air introduced through the first communication portion 610 is rib ( Compared with the conventional structure without 70, most will be supplied directly to the laundry through the drum opening 310.

Rib 70 is preferably provided with a material having an elastic force. Even if the length of each rib 70 is secured in consideration of the distance between the tub 20 and the drum 30 and the like, the vibration of the drum 30 may be momentarily increased in an unavoidable situation. This is because a situation in which the 30 and the rib 70 collide may occur.

Therefore, inevitably, even if the drum 30 and the rib 70 collide, the material of the rib 70 has a hardness in order to minimize the damage occurring on the surface of the drum 30 and to minimize the influence on the rotation of the drum 30. It is preferable that the material is low and has a large elastic force.

7 shows that the second communication unit 630 of the air circulation passage 60 protrudes a predetermined distance from the tub 20 to the outer circumferential surface of the drum 30.

When the second communication portion 630 protrudes toward the outer circumferential surface of the drum 30, a larger amount of air in the drum 30 flows into the second communication portion 630. Air inside the drum 30 is introduced into the second communication unit 630 through the through hole 31 provided in the drum 30.

In addition, a predetermined amount of air introduced between the tub 20 and the drum 30 through the first communication portion 610 and the tub opening portion 210 in turn may be formed in the second communication portion 630 protruding into the tub 20. The friction with the outer wall, the air in the space between the tub 20 and the drum 30 is more difficult to flow out to the second communication portion (630).

It is preferable that the length of the second communication portion 630 protruding toward the outer circumferential surface of the drum 30 is also shorter than the shortest distance between the tub 20 and the drum 30. This is because the drum 30 and the second communication unit 630 should not contact due to the vibration generated when the drum 30 is rotated.

The present invention may be practiced in various forms and is not limited to the above-described embodiment. Therefore, if the modified embodiment includes the components of the claims of the present invention will be seen as belonging to the scope of the present invention.
