In addition, the present invention may further include a circulating duct (7) for circulating air inside the clothes receiving portion. The circulation type clothes processing apparatus and the exhaust type clothes processing apparatus are mixed with each other as the circulation duct (7) is provided to circulate a part of the air in the clothes accommodating section and the air is exhausted to the exhaust duct (83) Device can be provided.

Hereinafter, for the sake of convenience of description, a clothes processing apparatus including the circulating duct 7 will be described.

The circulating duct 7 may be provided on the upper circumferential surface of the tub 2 for drawing the air inside the tub 2 out of the tub 2 and guiding the air to the tub 2 again.

The tub 2 may be provided with a first communicating part 26 and a second communicating part 27 for coupling with the circulating duct 7.

2, the first communicating part 26 (see FIG. 2) is a channel for guiding the air inside the tub 2 to the circulating duct 7, and the second communicating part 27 connects the circulating duct 7 ) To the tub (2).

The second communicating portion 27 may be provided in the gasket 23. That is, the second communicating portion 27 is provided with a hole penetrating the gasket 23, and the air outlet of the circulating duct 7 can be coupled to the hole formed in the gasket 23.

The second communicating portion 27 may be provided on the circumferential surface of the tub as in the first communicating portion 26. When the second communicating portion 27 is provided in the gasket 23, The air can be supplied to the central portion of the drum 3 through the drum inlet 31, which is advantageous for increasing the heat exchange efficiency between the laundry and the air.

The heating unit provided to supply the heated air to the tub 2 may be provided with a fan 71 and a heater 73 provided in the circulation duct 7. The fan 71 not only allows the air inside the tub 2 to flow into the circulating duct 7 through the first communicating part 26 but also has a means for moving the air introduced into the circulating duct 7 to the tub 2 And the heater 73 is means for heating the air moving to the second communication portion 27 through the fan 71. [

In this case, the first communication portion 26 and the second communication portion 27 are disposed in a diagonal direction with respect to the cross section of the tub parallel to the ground on which the cabinet 1 is supported, and the heater 73 is disposed in the circulation duct And a portion extending along the longitudinal direction of the main body 7. The length of the flow path formed by the circulating duct 7 is made longer to secure a sufficient time for the air moving along the circulating duct 7 to be heated.

A part of the air supplied to the tub 2 through the circulating duct 7 is discharged to the outside of the tub 2 through the exhaust duct 83 and is discharged to the outside of the tub 2 by the fan 71 A part of the air supplied to the heater (73) is supplied through the intake duct (81).

It is preferable that the intake duct 81 is provided on the flow path through which the air in the tub 2 flows into the fan 71. This allows the air circulation inside the tub 2 and the air outside the tub 2 to be circulated through the circulation duct 71 by only the fan 71 provided in the circulation flow path 71 without providing the air intake duct 81 with a separate air introduction means For example.

2 shows an example in which the air in the outside of the tub 2 is introduced into the circulating duct 7 through the first communication part 26 by the intake duct 81. [ In this case, when the fan 71 rotates, a negative pressure is formed in the first communication part 26, so that the air inside the tub 2 and the air outside the tub 2 flow into the circulating duct 7 will be.

In the meantime, the intake duct 81 provided in the present invention does not require a separate control means (valve or the like) for controlling opening and closing of the intake duct 81. That is, the intake duct 81 provided in the present invention may be provided so as to be always kept open.

1 and 2, the exhaust duct 83 communicates the inside of the tub 2 and the outside of the cabinet 1 to guide the air introduced into the exhaust duct 83 to the outside of the cabinet 1 It is preferable to connect the water supply duct 6 to the drain duct 6 provided to discharge the washing water in the tub 2.

Since the air discharged through the exhaust duct 83 is highly humid air, if the exhaust duct 83 is provided to directly communicate with the outside of the cabinet 1, the air discharged from the exhaust duct 83 is condensed on the indoor wall Because it can cause problems.

When the exhaust duct 83 is connected to the drain duct 6 because the drain duct 6 for discharging the washing water in the tub 2 to the outside of the cabinet 1 is provided in the garment treating apparatus 100 of the present invention, One problem can be solved.

The detailed structure of the drainage passage 6 will be described later.

In this case, the connection point between the exhaust duct 83 and the drain passage 6 is preferably provided with a passage switching portion 9 for controlling the opening and closing of the exhaust duct and the drain passage 6. The air discharged through the exhaust duct 83 is prevented from being re-introduced into the tub 2 and the water discharged through the drainage passage 6 is prevented from being reintroduced into the tub 2. [

It is preferable that the flow path switching portion 9 provided at the connection point between the exhaust duct 83 and the drain flow path 6 is provided at a position higher than the maximum water level H set in the tub 3 (see FIG. 5).

Conventionally, a garment processing apparatus generally has a structure (hereinafter referred to as a water trap) for preventing water from being completely discharged from a drainage channel to prevent odors from being introduced into a garment processing apparatus through a channel connected to an outdoor communication section .

When the exhaust duct 83 provided in the present invention is connected to the drainage passage provided with the water trap, the air inside the tub 2 can not be discharged to the outside of the tub 2 through the exhaust duct 83 when the laundry is dried . Therefore, when connecting the exhaust duct 83 to the drainage portion of the conventional clothes processing apparatus, the control unit must discharge the air with the pressure capable of removing the water trap through the control of the rotation speed of the fan.

However, when the flow path switching unit 9 is provided at a position higher than the maximum water level set in the tub 3 as in the present invention, since the exhaust duct 83 plays a role of preventing a siphon phenomenon, (Second drainage flow path) between the flow path switching portion 9 and the pump 63 to prevent the offensive odor from flowing into the tub 2.

Since the air introduced into the exhaust duct 83 can be discharged to the outside of the tub through the flow path switching unit 9, the rotation speed control of the fan 71 for removing the water trap is unnecessary.

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

The flow path switching unit 9 provided in the present invention may be provided as shown in FIG.

The duct switching unit 9 includes a switching unit body 91 provided at a connection point between the exhaust duct 8 and the drain duct, a duct connecting pipe 93 connecting the exhaust duct 83 and the switching unit body 91 A flow path connection pipe 95 connecting the drainage flow paths 61, 63, 65 and 67 and the switching body 91 to the switching body 91, And a discharge pipe 97 for guiding the introduced air or the washing water to the outside of the tub 2.

1, the drainage passage 6 includes a first drainage passage 61 for connecting the tub 2 and the drainage pump 63, a second drainage passage 61 for connecting the drainage pump 63 and the drainage pump 63, A third drainage passage 65 provided in the drainage pipe 97 and communicating the inside of the switching unit body 91 with the outside of the tub 2, . ≪ / RTI >

The first drainage flow path 61 discharges the washing water in the tub to the outside of the tub and the washing water guided to the flow path switching part 9 through the second drainage flow path 65 flows through the third drainage flow path 67 To an outdoor communication section such as a sewer.

3, the duct connecting pipe 93 and the flow path connecting pipe 95 are provided to face each other, and the duct connecting pipe 93 is provided on the upper portion of the switching unit body 91, It is preferable that the pipe 95 is provided below the switching unit body 91.

The necessity of the positional relationship between the duct connecting pipe 93 and the flow path connecting pipe 95 will be described in detail together with the action of the switching valve 99 to be described later.

The switching unit body 91 may further include a switching valve 99 for opening and closing the duct connecting pipe 93.

The switch valve 99 is normally maintained in a state in which the duct connecting pipe 93 is opened due to its dead weight.

In order to prevent the washing water from flowing back to the duct connecting pipe 93 when the washing water flows into the switching body 91 through the drainage passage 6, (93) is closed.

The duct connecting pipe 93 is provided on the upper part of the switching part body 91 and the flow path connecting pipe 95 is provided on the lower part of the switching part body 91 on the basis of the operational aspect of the above- .

That is, when the duct connecting pipe 93 is provided at the upper part of the switching part body 91 and the flow path connecting pipe 95 is provided at the lower part of the switching part body 91 as in the present invention, The switching valve 99 may be closed only when the valve 99 is always open and the washing water flows into the flow path connecting pipe 95 located below the switching body 91. [

Conversely, when considering the case where the duct connecting pipe 93 is provided at the lower part of the switching part body 91 and the flow path connecting pipe 95 is provided at the upper part of the switching part body 91, The switch valve 99 should be opened by applying a force in the direction opposite to the gravity force to open the switch valve 99 and the switch valve 99 is closed by its own weight when the wash water flows through the flow path connector pipe 95.

Therefore, in this case, since the switching valve 99 must be opened against the gravity as usual in contrast to the present invention, the energy required is greater than the present invention.

For this reason, it is preferable that the duct connecting pipe 93 is provided on the upper part of the switching part body 91 and the channel connecting pipe 95 is provided on the lower part of the switching part body 91 in order to reduce power consumption .

The switching valve 99 includes a valve body 991 for opening and closing a duct connecting pipe 93 and a valve rotating shaft 993 for rotatably coupling the valve body 991 to the switching body 91 .

If the flow path switching unit 9 is provided only by the above-described structure, the washing water discharged from the tub can be prevented from flowing into the tub 2 through the duct connecting pipe 93, There is a problem that it is not possible to exclude the possibility of being supplied again to the tub 2 through the coupling pipe 95.

Therefore, the flow path switching unit 9 provided in the present invention may further include a flow path valve 951 for opening and closing the flow path connecting pipe 95. The flow path valve 951 may be provided as a check valve to open the flow path connection pipe 95 only when the wash water flows into the switching part body 91 through the second drainage flow path 65.

That is, when the switching body 91 of the present invention has both the switching valve 99 and the flow path valve 951, the action of the valve is as follows.

The switching valve 99 for opening and closing the duct connecting pipe 93 provided at the upper portion of the switching unit body 91 maintains a state of being opened by its own weight, The flow path valve 951 for opening and closing the pipe 95 is kept closed by its own weight.

Thereafter, when the washing water flows into the switching body 91 through the flow path connecting pipe 95, the closed flow path valve 951 is opened and the switching valve 99 which has been opened is closed so that the washing water flows into the duct connecting pipe 93 to the outside of the tub through the discharge pipe 97 without backflow.

4 shows another embodiment of the flow path switching unit 9 of the present invention.

The duct connecting pipe 93 and the discharge pipe 97 are provided on the switching unit body 91 so as to face each other and the duct connecting pipe 93 is connected to the flow channel connecting pipe 95, (97).

According to one embodiment, the switching valve 99 includes a ball 995 reciprocable within the duct connecting pipe 93 and a ball 995 discharged from the duct connecting pipe 93 as shown in FIG. And a stopper 997 for preventing the disconnection.

According to the embodiment shown in FIG. 4, the ball 995 is normally lowered by gravity, but the stopper 997 is provided in a rod shape so that the ball 995 is connected to the duct connecting pipe 93, It prevents you from getting out.

Of course, the shape of the stopper 997 is not limited to this as long as it is provided with a space through which air can move.

The ball 995 is positioned at the lower portion of the duct connecting pipe 93 by the stopper 997 and the air is introduced into the switching part body 91 from the duct connecting pipe 93 to be discharged from the discharge pipe 97, So that the clothes are discharged to the outside of the clothes processing apparatus 100.

When washing water is discharged from the flow path connecting pipe 95, a large amount of washing water flows in the gravity direction and is discharged to the outside through the discharge pipe 97. However, since some washing water passes through the flow path connecting pipe 95 and the discharge pipe 97 There is a risk of flowing backward through the duct connecting pipe 93 located between them.

However, according to the present invention, the ball 995 moves along the duct connecting pipe 93 by the water pressure as the washing water flows into the duct connecting pipe 93. The width of the duct connecting pipe 93 becomes gradually narrower toward the upper part so that the ball 995 moves along the duct connecting pipe 93 and completely blocks the duct connecting pipe 93.

Therefore, the passage is completely blocked by the ball 995 moved upward in the duct connecting pipe 93, and the washing water can not flow back through the duct connecting pipe 93.

Therefore, in the embodiment of the present invention shown in FIG. 4, only the switching valve 99 is provided, so that the washing water and the air can be discharged to the outside of the clothes processing apparatus through the discharge pipe 97 more efficiently.

1 and 2, in the case where the apparatus for treating clothes of the present invention includes a circulating duct 7 for taking out the air inside the tub 2 and guiding the air into the tub 2 And a cooling water supply unit 10 for supplying cooling water for condensing the circulating air.

The present embodiment is a system in which a part of air is exhausted to the outside and a part is circulated through the circulating duct 7 in order to compensate for the disadvantages of the conventional exhaust type clothes processing apparatus and the circulation type clothes processing apparatus, To supply the cooling water.

It is possible to obtain the effect of condensing the circulating air by supplying only a much smaller amount of cooling water than the conventional circulating clothes processing apparatus.

The position of the cooling water supply unit 10 is not limited as long as the cooling water flows into the tub and the cooling water can be supplied to cool the inner circumferential surface of the tub.

1 and 2, a clothes processing apparatus 100 according to the present invention includes a water supply unit 4 for supplying water required for washing to a tub 2, a water supply unit 4 for storing detergent, And a detergent supply unit 5 for supplying the detergent.

At this time, the cooling water supply unit 10 may be provided as a supply pipe connecting the detergent supply unit 5 and the tub 2, and the cooling water is supplied to the inside of the tub through the detergent supply unit 5.

6, the cooling water supply unit 10 is disposed at a position spaced apart from the vertical line X passing through the center C1 of the tub 2 along the width direction Y of the tub by a predetermined distance X1 .

When the cooling water supply unit 10 is provided at such a position, even if water is supplied into the tub 2 during drying, the cooling water flows along the inner circumferential surface of the tub to prevent the laundry stored in the drum 3 from being wetted with water Because.

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
