  According to the present invention, in the drum type washing and drying machine, the filter holding frame can be securely attached to the lint collecting portion that collects lint such as lint generated when the laundry is dried. Therefore, it is possible to provide a drum-type washing and drying machine having a function of reliably preventing a failure from being caused by lint scattered.

  FIG. 1 shows a configuration of a main part of a drum type washing and drying machine 1 according to an embodiment. A water tank 3 is suspended in a housing 6 by a suspension structure (not shown), and a bottom is formed in the water tank 3. A rotating drum 2 formed in a cylindrical shape is disposed with its axial direction inclined downward from the front side to the back side. On the front side of the water tank 3 is formed a clothing doorway 11 leading to the opening end of the rotary drum 2, and a door 9 that closes the opening provided on the upward inclined surface formed on the front side of the housing 6 so as to be openable and closable. By opening, the laundry can be taken in and out of the rotary drum 2 through the clothing entrance 11. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be carried out without bending the waist, and generally the workability of the drum type washing machine for taking in and out the laundry from the sideways opening is provided. The evil has been improved.

  The rotary drum 2 is formed with a large number of through holes 8 communicating with the water tank 3 on its peripheral surface, and provided with stirring protrusions (not shown) at a plurality of positions on the inner peripheral surface. The rotating drum 2 is rotationally driven in the forward and reverse directions by a motor 7 attached to the back side of the water tank 3. In addition, a water injection pipe 12 and a drain pipe 13 are connected to the water tank 3, and water injection and drainage into the water tank 3 are performed by controlling a water injection valve and a drain valve (not shown).

When the door 9 is opened and laundry and detergent are put into the rotary drum 2 to start the operation of the drum-type washing and drying machine 1, a predetermined amount of water is injected into the water tank 3 from the water injection pipe 12. 7, the rotary drum 2 is rotationally driven to start the washing process. By the rotation of the rotating drum 2, the laundry accommodated in the rotating drum 2 is lifted in the rotating direction by the stirring protrusion provided on the inner peripheral wall of the rotating drum 2, and the stirring operation of dropping from the lifted appropriate height position Is repeated, so that the laundry has the effect of tapping and washing. After the required washing time, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 2 at a high speed. Rinsing is performed by pouring water from the passage 12. Even laundry contained in the rotary drum 2 is stirred operations to more lifted and dropped may be practiced rinsed repeated stirring impact force by the rotation of the rotary drum 2 in this rinsing step.

  The drum-type washing / drying machine 1 has a function of drying laundry stored in the rotary drum 2. The air in the water tub 3 is exhausted to dehumidify and be heated to dry air. A circulation ventilation path for blowing air again into the water tank 3 is formed. FIG. 2 shows the configuration of the circulation fan path, and by rotating the blower fan 15 disposed in the circulation fan path, an air flow is generated in the circulation fan path to accommodate the laundry. The air in the rotating drum 2 is exhausted from the exhaust port 21 of the water tank 3 to the dehumidifying conduit (dehumidifying part) 16 through the through hole 8. Since the dehumidification pipe line 16 is cooled by spraying water supplied from the water supply pipe line 12 or the like, the air containing moisture exhausted from the water tank 3 is cooled, and moisture is condensed and dehumidified.

  The air duct 18 connected to the dehumidifying duct 16 is formed as a duct that guides air to the back side of the water tank 3 through the yarn waste collecting portion 17 disposed in the vicinity of the clothing entrance 11. It connects with the heating pipe line 19 arrange | positioned by the side. As shown in FIG. 3, the heating pipe line 19 is formed in a circular arc shape around the motor 7 above the motor 7 attached to the back surface of the water tank 3, and a connection position with the blower pipe line 18 is formed therein. A blower fan 15 is disposed at the other end, a blower opening 22 leading to the water tank 3 is formed at the other end, and a heater (heating unit) 20 is disposed at an arcuate bent portion. The air passing through the heating pipe 19 is heated to a predetermined temperature by the heater 20, blown into the water tank 3 from the blower opening 22 as dry hot air, and fed into the rotary drum 2 through the through holes 8. The laundry agitated by the rotation of the rotating drum 2 is dehydrated by the dry warm air, and the drying proceeds. The laundry is dried by repeating this air circulation for a required time.

  As shown in FIG. 4, the lint collecting part 17 disposed in the circulation air passage includes a handle 31 a for inserting and removing the filter holding frame 31 at the peripheral part of the clothing entrance 11 formed in the water tank 3. The filter holding frame 31 is disposed so that the filter holding frame 31 can be inserted and removed in an upwardly inclined direction from within the opening of the clothing entrance 11. As shown in FIG. 5, the filter holding frame 31 has a handle 31a portion constituting a part of the peripheral edge of the clothing entrance 11 and is formed in an arc shape obtained by cutting out a part of the clothing entrance 11 that opens in a circular shape. A plurality of window frames 33 in which filters 32 are spread are formed at portions of the air duct 18 connected to the dehumidifying duct 16 and connected to the heating duct 19.

  This filter holding frame 31 is formed so that the width of the handle 31a portion, which is one end in the insertion / removal direction, is larger than the width of the other end 31b in the insertion / removal direction, and is formed in the yarn waste collecting portion 17. The lower sliding surface 31d that slides on the receiving portion has a large upward inclination angle. As described above, the insertion / removal direction is an upward inclined direction, and the widths at both ends of the insertion / removal direction are different. Therefore, even if the filter holding frame 31 is inserted into the lint collection part 17, it falls into the clothing entrance 11 due to its own weight or vibration. It will end up. Therefore, when the filter holding frame 31 is inserted into the lint collecting portion 17 and securely attached, the upper sliding inclination of the filter holding frame 31 is formed in the recess 17a formed in the sliding receiving portion of the lint collecting portion 17. The fitting protrusion 34 formed on the surface 31c is fitted and locked at the mounting position.

  As described above, if the filter holding frame 31 is not securely attached to the lint collecting portion 17, it will fall off, and a mechanism for urging the user to reliably attach the filter holding frame 31 is configured. Further, as shown in FIG. 6, the lower sliding inclined surface 31d of the filter holding frame 31 is formed into an arc whose inclination direction is downwardly inclined at all positions, so that it is more easily dropped when mounting is incomplete. It is easy to do.

  As shown in FIGS. 5B and 6B, the surface on which the filter 32 is spread on the filter holding frame 31, that is, the portion where the window frame 33 is formed is an inclined surface so as to form an elevation angle with respect to the blowing direction. As a result, the collection ability of the lint contained in the blown air can be improved, and the lint deposited on the filter 32 can be prevented from peeling off. The lint accumulated on the filter 32 may cause a failure if it falls off and scatters on the air flow path. Therefore, the collected lint is removed from the surface of the filter 32 by the user removing the filter holding frame 31. It must be captured so that it will not fall off until it is peeled off.

  In order to further improve the ability to capture the accumulated lint, it is preferable to project a lint drop-off preventing projection 35 at the intersection of the crosspieces forming the window frame 33 as shown in FIG. The lint drop-off preventing projection 35 penetrates into the accumulated lint in a wedge shape, and the effect of preventing lint drop-out can be further improved.

  According to the present invention, when the drum-type washing machine is provided with a drying function, the filter holding frame can be securely attached to the lint collecting portion that collects lint such as lint generated when the laundry is dried. Thus, it is possible to reliably prevent the occurrence of trouble due to lint scattered due to imperfect mounting, and to provide a drum-type washing and drying machine with improved performance of the drying function.
