[0008]

In the case of the above-mentioned conventional apparatus, it is inevitable that lint such as lint will be generated from laundry such as clothes in a washing operation, but lint capture which functions sufficiently with this type of washing and drying machine is inevitable. It was difficult to provide a means. The reason is that the drum 4 is constantly driven to rotate in all of the washing, dehydrating and drying operations, and it is not possible to easily provide a lint capturing means. In addition, even when the lint is captured from the washing water, the washing water is only stored in a bottom region that does not reach the lower edge of the opening 2a of the water tub 2, and the lowest portion where the drain hose 11 is connected to the bottom is And a heater 9 for generating heat during washing, and a narrow gap between the water tank 2 and the drum 4 is not suitable for providing a lint capturing means. This is because it is necessary to easily remove the lint that has been trapped and removed.

On the other hand, lint generated during the washing operation tends to adhere to clothes as laundry in a wet state, and in that state, the lint is not so noticeable. However, the lint also dries and releases as the clothes, which are laundry, dries, including those remaining without being discharged at the time of drainage, and the lint generated at the time of drying enters and exits the drum 4. The amount of water is remarkably increased due to floating or the like, which is discharged at the next drainage of washing water, or causes a problem such as re-adhering to clothes without being discharged. Further, discharging the lint outside the machine is not preferable from the viewpoint of clogging a water channel of a drainage place or environmental protection.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances. Accordingly, an object of the present invention is to provide a lint catch box in an outer hose portion of a drainage hose to capture lint from drainage and capture lint.

[0015] In the first or second aspect of the present invention, the lint filter is configured to have a comb-shaped capturing portion (the invention of claim 3).

According to such a configuration, since the lint such as lint is trapped and the entangled portion is formed as a comb-teeth-shaped capture portion extending in one direction, the entangled lint is easily slid in the comb-teeth direction. The lint filter can be cleaned very easily and reliably.

[0017] In the first aspect of the present invention, the lint filter is characterized in that a comb-like capture portion is formed integrally with the lint capture box (the invention of claim 4).

According to such a configuration, the lint filter can be easily formed by the die forming along the comb tooth direction, and the cost can be reduced, and the lint removal operation can be easily performed because of the comb-shaped capturing portion. it can.

In the first or second aspect of the present invention, the lint filter is characterized in that two filters having comb-shaped capturing portions are combined in a cross shape to form a lattice. 5 invention).

According to such a configuration, since the combination of the capturing portions is in a lattice shape, the lint is easily entangled, the capture rate is increased, and the lint that passes and is discharged can be reduced. On the other hand, the lint captured by the lattice capturing portion tends to be entangled in a complicated manner, but it is easy to move one of the filters in the comb-teeth direction. The lint remaining in the capturing section can be easily removed.

[0021] In the first aspect of the present invention, the lint capturing box is installed and fixed to an outer wall of the main body near the outlet of the outer hose section (the invention of claim 6).

According to such a configuration, the lint catch box is arranged on the base end side of the outer hose section, so that the free end side of the outer hose section led out from the catch box can be made longer, so that a desired Can easily be directed toward the drainage area.

The general structure of the dehumidifier 41 is described below. The dehumidifier 41 is located at a position avoiding the drive motor 39, is entirely hollow, and has a lower end communicating with the inside of the water tank 28. The air in the drum 36 is taken in through, and while the air moves upward from the lower end, water is poured from above by a water injection means (not shown) to cool, condense, and dehumidify the water from the air. Things.

Therefore, the circulating air passage 4 having such a configuration
According to 0, the air in the drum 36 humidified by the blowing operation in the direction of the arrow by the blower 42 during the drying operation is sucked into the dehumidifier 41 through the water tank 28, where the air is dehumidified and the air is heated by hot air.

As described above, the drainage hose 35 connected to the bottom of the water tank 28 through the drainage valve 33 and having a distal end led out to the outside of the machine is provided. The lint capturing means will be described. First,
The specific configuration of the drain hose 35 will be described. In the present embodiment, an internal hose portion 45 provided inside the main body 21 and the main body 2 are provided.
1 and an outside hose section 46 led out of the machine. The inner hose part 45 has a base end connected to the drain valve 33 and another end connected to a tubular hose joint 47 as shown in FIG. The hose joint 47 extends through the lower part of the
Is fastened and fixed by a tubular body 47a and an annular nut member 47b so as to sandwich the outer wall. The base end of the bellows-shaped outside hose portion 46 is connected to a portion of the hose joint 47 projecting outside the machine, and the free end on the tip side is directed to a predetermined drainage place.

FIGS. 1, 5 and 6 disclose a specific configuration of the external hose portion 46 and the above-described lint capturing means provided on the external hose portion 46. FIG. First, FIG. 1 is a side view of a main part of the main body 21 from which an external hose portion 46 is led out, and a lint trap box 49 functioning as a lint trap.
Is disposed in the middle of the external hose portion 46, and therefore, the external hose portion 46 is derived from the base end side first hose portion 46a derived from the main body 21 and the lint catch box 49. It is in a form separated from the second hose portion 46b on the free end side which is the downstream side.

In this embodiment, however, the lint trap box 49 is used.
Is located near the outside of the main body 21 and is connected to a first hose 46a at a water inlet 50 and a second hose 46b to a water outlet 51 on the opposite side. I have. The lint trapping box 49 has two hook-shaped engaging pieces 52 (in particular, see FIG. 5) protruding from the outer surface of the lint catching box 49. The main body 21 is fitted and fixed to the outer wall of the main body 21 at a predetermined height by being hooked and held.

As shown in the enlarged perspective view of FIG. 6, the lint trapping box 49 has a rectangular parallelepiped container-shaped synthetic resin box 53 having an open upper portion, and an upper opening thereof. And a shallow container-like lid 54 made of a resin, which is provided so as to be capable of being provided. The lid 54 extends in the front-rear direction (the left-right direction in FIG. 1) along the outer wall surface of the main body 21 via the hinge portion 55. It is pivotally supported. The box 53 on the side opposite to the hinge portion 55 is provided with a stopper 56 which is engaged with and disengaged from the lid 54, so that the lid 54 can be kept in a closed state.

However, the periphery of the opening of the box body 53 has a flange 57 projecting outward, and a packing 58 is buried in the upper surface concave portion, while the lid 54 opposed to the packing 58 is provided.
Ribs 59 are protrudingly provided on the peripheral edge of the packing 54. When the lid 54 is closed, the ribs 59 elastically press the packing 58 to obtain a watertight state without water leakage. Is reliably maintained. In addition, the box 53
The lower part of the outer side surface having the engagement piece 52 is provided with two projections 60 protruding equally to the protrusion of the flange 57 as shown in FIG. When fitted and hooked at the abutment 21b, the flange portion 57 and the projection 60 abut on the outer wall surface of the main body 21 so that the lint capturing box 49 can be installed in a substantially horizontal state.

A detachable lint filter 61 is provided inside such a lint trap box 49. Specifically, as shown in FIG.
For example, a guide groove 62 extending in the vertical direction (up and down direction in the drawing) is formed substantially in the middle of each of the inner sides of the opposing side walls, and can be inserted and removed from above along the guide grooves 62 and 62. The lint filter 61 is stored.
The lint filter 61 has a configuration in which a trapezoidal portion 61a having a rectangular plate-like outer shape and integrally formed in a coarse lattice shape with synthetic resin, for example, and a frame portion 61b around the outer periphery are provided. Water flow direction (indicated by dashed arrow 48 in the figure)
It is arranged to face.

By the way, the total area of the lattice-like coarseness through which the lint filter 61 allows water to flow is determined by the external hose portion 46.
The lint trap box 4
The so-called drainage efficiency is prevented from being reduced by minimizing the resistance to the flow of water flowing into the interior 9. Incidentally, in FIG. 3 and FIG.
8 is provided with a packaging bracket 63 having an upward U-shape, which has an excellent strength and engages with a bottom buffer of a packaging device (not shown) at the time of packaging to provide an elastically supported water tank 28.
To prevent shaking.

Next, the operation of the drum type washer-dryer having the above configuration will be described. First, the door 24 is opened, and laundry (not shown) is put into the drum 36 through the openings 21a, 28a, and 36a on the front surface through which laundry is taken in and out. Also, a necessary detergent is put in the detergent input case 23 and set. Then, when the door 24 is closed and the necessary switches on the operation panel 22 are operated to set the operation conditions and start the operation, the operation is started based on the program stored in the control device 27 in advance, and the washing operation and the drying operation are performed. Are sequentially performed.

Therefore, when the washing operation is started, the water tank 2 is started.
A predetermined amount of water is supplied as washing water into water 8 through a water supply means (not shown), the detergent in the detergent charging case 23 is charged, and the drum 36 is rotated at a low speed by the drive motor 39. The washing process of the laundry is executed. That is, the laundry is repeatedly immersed in the washing water at the lower part in the drum 36, lifted in the rotating direction by the baffle 36c, and then dropped downward.
A washing operation of the laundry is performed. In this washing process, the heater 32 for hot water always in the water generates heat, and the washing water is heated to make it warm, thereby improving the washing effect.

After a predetermined time, the drive motor 39 is stopped, the geared motor 34 is energized and the drain valve 33 is opened. As a result, the dirty washing water in the water tub 28 is discharged from a drain port (not shown) of the recess 31 through the drain valve 33 and the drain hose 35 to a drain place outside the machine. However, since the drainage hose 35 is provided with a lint catching means for this drainage, lint such as lint generated in the washing process is captured from the wastewater and is not discharged to the drainage place as it is.

Here, the operation of the lint capturing means in this embodiment will be described in detail below. That is, in the present embodiment, a container-shaped lint catch box 49 is provided in communication with the outside hose portion 46 of the drainage hose 35 which is led out of the machine from the main body 21. As shown in FIG. 6, a lint filter 61 mainly composed of a lattice-like capture portion 61a is mounted inside the interior. Accordingly, the lint flowing down in the drainage hose 35 together with the washing water is captured from the drainage flowing in the lint capture portion 49 in the direction of the dashed arrow 48 so as to be entangled with the lattice-like capture portion 61a, and is sequentially accumulated.

However, when the lint is trapped and stored in the lint trap box 49, the lid 54 can be rotated and opened via the hinge 55 if the stopper 56 of the lid 54 is removed. The inside can be easily inspected visually. In this case, as shown in FIGS. 1 and 5, the lint capturing box 49 can be easily installed and fixed on the outer wall of the main body 21, and even if there is a small amount of residual water in the box 53, the lint capturing box 49 may leak to the outside. The same can be said for the case of attaching and detaching the lint filter 61 described later.

As a result of the inspection, when removing the lint from the lint filter 61, the lint filter 61 can be easily removed by sliding the guide grooves 62, 62 and pulling out the lint filter 61 upward. , And then re-attach. At the time of the drainage, for example, a state in which a large amount of lint is accumulated, such as a clogged state of the lint filter 61, or a drainage passage is obstructed by some factor in the downstream area, so that a smooth drainage operation is performed even temporarily. If not, the water level in the lint trap box 49 will increase and there is a possibility that the water will pass over the opening edge of the box 53, but the rib 59 of the lid 54 will be pressed tightly against the packing 58 at the opening edge of the box 53. Therefore, water does not leak from the lint capturing box 49 to the outside.

When the draining operation is completed, a new amount of water is supplied into the water tank 28, and the drum 36 is again rotated at a low speed by the drive motor 39, so that the washing operation is substantially the same as the washing operation. A rinsing process is performed.
However, at the time of this rinsing, the heater 32 for hot water is not energized and does not generate heat. Thereafter, the same drainage operation as described above is performed from the inside of the water tub 28, and the drum 36 is rotated at a high speed by the drive motor 39, thereby performing the dehydration process of the laundry. Therefore, if lint generated in the previous stage of rinsing or the like is mixed in the drainage water and the drainage water in the dewatering process, the lint is effectively captured in the lint capture box 49 as described above.

When this dehydration step is completed, a series of washing operations is completed, and subsequently, a drying operation is started. In this drying operation, the drum 36 is rotated at a low speed by the drive motor 39, and the air flowing through the duct 44 (circulating air passage 40) due to the driving of the blower 42 is hot-airized by the hot air heater 43 that is also energized and heated. , Drum 36. On the other hand, the air containing a large amount of water in the drum 36 (including hot air that has contributed to drying) is taken into the dehumidifier 41 from the rear part of the water tank 28 through the through-hole 36b, and is drawn from above into the air. When water is poured through a non-water injection means, the water is cooled and condensed and drops or flows down,
The dehumidified and dried air is sent to the hot-air heater 43 and is efficiently heated again, and the circulation returning to the inside of the drum 36 is repeated.

As a result, while the laundry is subjected to the stirring action of being lifted and dropped by the baffle 36c in the drum 36, the newly generated hot air is constantly blown through the circulation air passage 40, and gradually. Dried. Then, the moisture evaporated from the laundry during the drying is condensed by the dehumidifier 41 and flows down as described above, and the water tub 28
Through the inside, the water is discharged to the outside through the drain valve 33 and the drain hose 35. However, it can be confirmed that the lint floats in the drum 36 even during such a drying operation. This includes those newly generated by the drying operation, but what originally adhered to the laundry due to the wet state of the lint generated during the washing operation (washing and rinsing) becomes more and more as the drying proceeds. Often noticeable due to release from the laundry. Therefore, the lint generated during such drying is discharged together with the washing water at the time of drainage of the next washing operation, captured in the lint capturing box 49, and thereby removed from the drum 36.

As described above, the present embodiment has the following effects. That is, among the drain hoses 35 communicating with the inner bottom of the water tank 28, a container-shaped lint capture box 49 having a built-in lint filter 61 is provided so that water can flow through the outer hose section 46. Although it is difficult to provide the drum 36 and the water tank 28 with the lint capturing means in the machine, according to this configuration, the lint can be reliably captured from the drainage water, and the various mechanisms and shapes in the main body 21 are specially structured. And the assembling and disassembling operations of the lint trap box 49 can be easily performed from outside the machine.

Further, since the lint trap box 49 is provided outside the machine, the degree of freedom in design is large, and the size of the volume can be freely set. If so, it is possible to capture and accumulate as much lint as it is, which is effective for making it usable for a long time. And the lint capture box 49
The lint filter 61 inside can be easily attached and detached because it is composed of the container-like box body 53 having an open top and the lid 54, so that the lid 54 can be opened and closed regardless of the residual water in the lint capture box 49. Of course, lint filter 6
The attachment and detachment of the lint can also be performed without any problem. Therefore, the lint removal operation of the lint filter 61 can be easily performed outside the machine consistently, and the lint capture box 49 can be installed and fixed on the outer wall of the main body 21. Also, the lint filter 61
Since the trapping portion 61a has a lattice shape as in this embodiment, lint having a relatively short dimension is easily entangled, and the trapping efficiency is improved. Furthermore, the box 53 and the lid 54 are
Since the closed state can be maintained in a watertight manner by the stopper 56 and the like, even if the drainage temporarily reaches a high water level, the drainage does not leak from the lint trap box 49 and the floor surface is not contaminated with water.

In addition, since the lint-capturing box 49 is installed and fixed near the outlet of the main body 21 near the base end of the external hose section 46, the lint-capturing box 49 of the external hose section 46 is set. The first hose portion 46a can be short, so that the first hose portion 46a does not drop down due to the weight of the water at the time of drainage, and the second hose portion 4 led out from the lint trap box 49.
The free end side, which is 6b, can be long and can easily be directed to a desired drainage place.

In this embodiment, the drain hose 35 is connected to the outside hose part 46 and the outside hose part 46 by a hose joint 47 at a position where the drain hose 35 extends out of the machine from the main body 21. Without limitation, for example, one continuous hose may be used up to the outside of the machine. Further, the lint capture box 49 is connected to the main body 21 by hook-shaped engaging pieces 52.
The lint capture box 49 need not be removed when the lint filter 61 is cleaned or attached or detached. Therefore, the lint capture box 49 may be fixed with screw fixing means.

7 to 15 show the second to sixth embodiments of the present invention, in which the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. Omitted, and only different parts will be described.

(Second Embodiment) First, FIGS. 7 and 8 show a second embodiment of the present invention. FIG. 7 is a diagram corresponding to FIG. 6, and FIG. It is sectional drawing cut | disconnected and shown along a line. In the present embodiment, a lint filter 64 of a different form is provided to the lint filter 61 of the first embodiment.

9 and 70 are housed in the box 53 in a two-layered manner so as to be orthogonal to each other. Accordingly, each of the comb-shaped capturing portions 69a and 70
a intersect with each other to obtain a lint filter 68 having a configuration substantially combined in a lattice shape, and to be detachable along the guide grooves 62.

The lint filter 6 configured as described above
According to 8, the lint can be effectively captured from the wastewater flowing in the direction of the dashed arrow 48 by the capturing portions 69a and 70a configured in a cross-shaped combination. In this case, the lint is liable to be entangled in different directions across the two capturing portions 69a and 70a, and it is usually not easy to remove the lint accumulated in the lint. However, in the case of the present embodiment, the combined lint filter is used. After taking out 68 from the box 53, if one of the first filters 69, for example, is pulled out in the direction of the comb teeth of the capturing section 69a, the lint is orthogonal to that of the other (the second filter 70). The first filter 69 remains so as to be squeezed on the side of the capturing section 70a.
Can be easily extracted.

Therefore, in order to remove the lint from the second filter 70, the catch 70a can be easily removed by sliding in the comb-teeth direction. As described above, in this embodiment, a lint-like combination is used to capture lint, and the comb-like advantage of easy removal is used to remove lint. In this embodiment, since the first and second filters 69 and 70 have the same shape, their combination is free as long as they intersect each other, and there is no restriction on the direction in which they are incorporated into the box 53. Although it has the advantage that it is not received, the above-described effects can be expected even if the shapes are different from each other, and the intended object of the present invention can be achieved.
