Description

  The present invention relates to a drum type washing and drying machine for washing and drying clothes.

  A drum-type washing and drying machine has a drum rotatably arranged in a horizontal or substantially horizontally inclined water tank, and the drum is rotated around a rotating shaft to wash, rinse and dehydrate laundry. , Until drying. To dry moisture-containing laundry, the air inside the drum containing moisture is exhausted out of the water tank, dehumidified by the dehumidifying means, heated by the heating means, and dried by being pressurized and accelerated by the fan. The laundry is dried by repeating the drying cycle of evaporating moisture from the laundry by blowing the air into the drum.

  The exhaust port that exhausts the moist air and the air inlet that blows dry air are one side of the aquarium so that the air blown into the drum is exhausted from the exhaust port after passing through the inside of the laundry. It is desirable that the front surface and the other be disposed on the back surface of the water tank.

  In order to perform such a drying cycle efficiently, it is necessary to reduce the ventilation resistance of the air circulation path from the exhaust port for exhausting air from the drum to the blow-in port. However, if the cross-sectional area of the air circulation path is increased in this way, the drying section for carrying out the drying cycle becomes larger, so the entire drum-type washing and drying machine is useless. There is a problem of increasing the size.

  The prior art will be described with reference to FIGS. FIG. 5 shows a conventional technique in which the air is exhausted from the front surface of the water tank 4 and blown from the back surface of the water tank 4.

  In FIG. 5, humid air is sucked from an exhaust port 12 that is opened on the substantially upper surface of the water tank 4 and close to the front surface of the water tank 4, and is cooled in a dehumidification duct 13 that is a dehumidifying means provided along the upper side surface of the water tank 4. The moisture is removed. Thereafter, the lint is removed by passing through a filter 16 for removing fiber lint (lint) contained in the air, and further introduced into the fan 18 through the communication path 17. This fan is a so-called centrifugal sirocco fan or turbo fan, which sucks air from the vicinity of the rotating shaft of the rotary blade 19 rotated by the fan drive motor 20 and is accelerated by the centrifugal force in the outer circumferential direction by the rotary blade 19. Discharge. The air discharged from the fan 18 is heated by a heater 21 which is a heating means to be dried warm air, and is blown into the aquarium 4 through a blowing duct 22 from a blowing port 23 provided on the back surface of the water tank 4. Then, the laundry inside the drum 5 is dried. In this prior art, the heater 21 as a heating means is an example using a PTC heater having a mesh-like fin (with a self-temperature control characteristic that automatically becomes low power when the temperature rises), and a heater by lint. The filter 16 is necessary to prevent clogging of the 21 fins. In the prior art of FIG. 5, since the water tank 4 is inclined backward, the space between the washing / drying machine body 1 and the water tank 4 is wider at the rear than at the front where the opening 6 is provided. Therefore, by providing the fan 18 at the rear part of the water tub 4, the outer shape of the washing and drying machine main body 1 can be configured without unnecessarily increasing the size.

  Since the filter 16 removes lint attached by the user, the filter 16 is fixed to the washing / drying machine main body 1 and is connected to the vibrating water tank 4 by a bellows 15.

FIG. 6 shows a conventional technique in which the air is exhausted from the back surface of the water tank 4 and blown from the front surface of the water tank 4.
In FIG. 6, an exhaust port 12 is provided on the back surface and the vicinity of the bottom surface of the water tank 4, and is heated by a heater 21 through a fan 18 provided on the upper surface of the water tank 4. Blow inside. In the configuration shown in FIG. 6, since the heater does not have a mesh-like fin, a so-called sheathed heater which is a heating wire heater that does not require a filter is used.

  In the configuration of FIG. 6, since no filter is required, the drying means 11 is attached to the water tub 4, and the washing / drying machine main body 1 is disposed with a gap larger than the amplitude at which the water tub 4 vibrates.

  In the prior art shown in FIGS. 5 and 6, the fan 18 is arranged such that the rotating shaft of the rotary blade 19 is orthogonal to the rotating shaft of the drum 5. The fan bottom surface 39, which is the surface closest to the outer tub 4, is arranged in parallel, and the distance between the fan bottom surface 39 and the cylindrical surface of the water tub 4 surface is uniform in the direction of the rotation axis of the drum 5. .

  Then, if the thickness of the fan part including the cylindrical surface of the water tank 4 to the fan drive motor 20 is the case of FIG. 5, even if the water tank 4 vibrates, the necessary clearance T1 that does not collide with the communication path 17 and T is the sum of the thickness T2 of the communication path 17, the thickness T3 of the fan 18, and the thickness T of the fan drive motor 20. In order to reduce the ventilation resistance of the air flowing into the fan 18, it is desirable to increase the thickness of the communication path 17. However, since the thickness T of the fan portion increases, there is a limit to downsizing.

  An object of the present invention is to provide a drying means for efficiently dehumidifying the humid air exhausted from the rotating drum and preventing an increase in the size of the drum type washing and drying machine.

For the above purpose, the drum type washing and drying machine according to the present invention comprises a cylindrical water tank that is elastically supported horizontally or inclined with one surface as an open end and the other end as a bottom surface, and the water tank inside the water tank. A rotating drum having a cylindrical shape that is rotatably supported concentrically and having one end as an open end, a lid provided to be openable and closable at the opening end of the water tank and the rotating drum, a motor that rotationally drives the rotating drum, A blower fan that blows air from the exhaust port to the blower port, and a filter that collects fiber waste in the air, and the blower fan has a smaller diameter than the fan body concentrically with the fan body. The motor part is formed in a convex shape, an air inlet is provided on the surface opposite to the motor part, and is inclined in a direction perpendicular to the rotation axis of the rotary drum, and the air inlet of the blower fan and the air Distance from aquarium The filter is disposed on the side closer to the opening end of the water tank than the blower fan so that the distance on the side close to the opening end of the water tank is larger than the distance on the side close to the bottom surface of the water tank. A communication path that connects the air that has passed through the filter to reach the blower fan is provided in a direction from the opening end of the water tank toward the bottom surface of the water tank, and air accelerated by the blower fan is supplied to the rotating drum. A blowing port for blowing inside is provided at a front edge of the water tank, and the filter, the blower fan, and the blowing port are arranged at an upper right corner when viewed from the front surface of the water tank .

  According to the present invention, the fan is disposed to be inclined around the rotation axis of the water tank, and is located in the front-rear direction with respect to the water tank, and the front side of the washing and drying machine main body is between the fan and the water tank. By making the direction wider than the back side, there is an effect that the area of the flow path flowing into the fan from the front side can be enlarged and the ventilation resistance can be reduced.

  In addition, the fan is located at the corner of the washer / dryer body, and the motor is placed outside the fan body to enter a small space, and the corner of the washer / dryer body can be made into a larger arc shape. There is an effect that it is suitable for downsizing of the washing / drying machine main body.

  Furthermore, the air flow path from the dehumidification duct to the filter via the connection air passage and the air flow path from the fan to the blowing duct via the heater are substantially parallel along the circumferential surface of the water tank. Since the dimensions of the drying means in the direction of the water tank rotation axis can be shortened, the depth dimension of the washing / drying machine main body can be reduced, and there is an effect that it is suitable for downsizing.

  In the drum type washing / drying machine main body 1, a water tank 4 whose front side is opened on a base 3 is supported by a suspension 2 so as to be inclined substantially horizontally, and the suspension reduces vibration during operation of the water tank 4. In addition, an elastic force generated by the spring and a damping force are generated by enclosing oil, for example. Inside the water tank 4, a rotating drum 5 that is pivotally supported and opened on the front side is disposed, and is rotated by a driving force of a driving motor 8 provided on the back surface of the water tank 4. An opening 6 is formed on the front side of the drum-type washing / drying machine main body 1, and the user puts the laundry 14 into the drum through the opening 6, or the laundry 14 after washing / drying is completed. It can be taken out. For taking out the laundry 14, a lid 7 for opening and closing the opening 6 is provided. For example, the lid 7 is pivotally supported and can be opened to the open position shown by 7 '.

  The opening 6 on the front side of the main body 1 and the front side of the water tank 4 are connected by a bellows 9 formed of a flexible material such as rubber, for example, and when the lid 7 is closed, a part of the bellows 9 is connected. Is in contact with the lid 7 to ensure water sealing even when the water tank 4 vibrates.

  When the drum-type washing / drying machine main body 1 is viewed from the lid 7 side on the front surface, a detergent loading unit 10 for loading detergent is disposed at the upper left corner of the water tank 4. Details are omitted here.

  A drying means 11 is disposed at the upper right corner when viewed from the front of the water tank 4. The drying means 11 in the present invention includes a dehumidifying duct 13, a filter 16, a communication path 17, a fan 18, a heater 21, a blowing duct 22, and a connection air path 24.

  Moist air containing moisture from the laundry 14 inside the drum 5 is discharged in the direction of the arrow 30 from the exhaust port 12 provided at the lower back of the water tank 4, and cooling water, for example, is supplied from the lower side to the upper side along the rear surface of the water tank 4. A dehumidifying duct 13 including a dehumidifying means such as a heat exchanger that dehumidifies by condensing moisture in the humid air by flowing and cooling the humid air is provided. The water tank 4 and the dehumidifying duct 13 are connected by a bellows 15 that can be expanded and contracted. On the upper surface of the outer tub 4, the dehumidification duct 13 is connected to the connection air passage 24, the connection air passage 24 extends toward the front surface substantially along the rotation axis of the drum 5, and the air blows in the direction of the arrow 31. Is done. The connection air path 24 is connected to the filter 16, and the filter 16 collects lint that is fiber waste contained in the air. The filter 16 is provided so as to be removable from the front side of the washer / dryer body 1, and the user can remove the filter 16 and clean the collected lint. Details of the configuration of the filter 16 will be described later.

  The air in which the lint has been collected in the filter 16 passes through a communication path 17 provided between the water tank 4 adjacent to the filter 16 and connected to the fan 18 in the direction of the arrow 32. It is introduced into the center of rotation of the rotary blade 19 provided inside. As described above, the fan 18 is a so-called centrifugal sirocco fan or turbo fan, and the rotating blade 19 is rotated by a fan drive motor 20 to accelerate air by centrifugal force. The outer shape of the fan 18 will be described. The rotary blade 19 has a substantially disk shape, and the main body of the fan 18 has a substantially cylindrical shape with a spiral shape in which the radius gradually increases around the rotary blade 19. The air blown out from around the fan is guided in the direction of the fan exhaust port. An opening for air to flow in is provided at the rotation center of the rotary blade 19 on one surface of the fan 18, and a fan drive motor 20 having a smaller diameter than the outer diameter of the fan 18 is provided on the opposite side of the opening. Concentric with 19 and protruded.

  The accelerated air is heated to dry air when passing through the heater 21, passes through the blow duct 22 through the bellows 25, and enters the interior of the drum 5 from the blow opening 23 that opens to the front surface of the water tank 4. Is blown in the direction indicated by the arrow 34. The warm air blown into the drum heats the laundry 14 to evaporate moisture to become moist air, which is sucked out of the water tank 4 through the exhaust port 12 and dehumidified again through the dehumidifying duct 13. The wet garment is dried by continuously repeating the drying cycle as described above.

  In the above description, it is assumed that the heater 21 uses a PTC heater as described in FIG. 5, and the filter 16 for collecting lint is necessary.

  Next, the arrangement of the fan 18 and the water tank 4 according to the present invention will be described in detail with reference to FIGS.

  FIG. 7 shows the relationship among the fan 18, the communication path 17, the water tank 4, and the outer shape of the washer / dryer main body 1 in the prior art described with reference to FIGS. 5 to 6. FIG. And is viewed from a direction orthogonal to both the rotation center axis of the fan drive motor 20 and the center axis of the water tank 4. FIG. 7B is a view of FIG. 7A viewed from the right side in the figure. FIG. 8 is a view showing the relationship among the water tank 4, the fan 18, the communication path 17, and the washing / drying machine main body 1 in the same manner as FIG. 7.

  As described above, in the drying means 11, it is desirable for increasing the performance to increase the cross-sectional area of the air circulation path to reduce the ventilation resistance. Here, when the bottom surface 39 of the fan 18 is arranged parallel to the central axis of the water tank 4 as shown in FIG. 7, the direction of the central axis of the fan 18 of the communication passage 17 that is a passage of the air flowing into the fan 18. The dimension or thickness T2 is constant in the direction of the fan bottom surface 39. Here, if T ′, which is the sum of the thickness T2 of the communication path 17, the thickness T3 of the fan, and the thickness T4 of the fan drive motor 20, is the total thickness of the fan portion, the increase in T ′ Therefore, increasing the thickness T2 of the communication path 17 has a limit.

  In the washing / drying machine according to the present invention, as shown in FIG. 8, the fan bottom surface 39 is not parallel to the central axis of the water tank 4, and the gap between the fan bottom surface 39 and the water tank 4 faces the vicinity of the opening 6 in the front surface. In other words, it is arranged so as to be inclined by an angle θ1 so that the rear side becomes narrower. When the fan 18 is inclined and disposed as shown in FIG. 8, the total thickness T ′ of the fan portion in the direction orthogonal to the central axis of the water tank 4 is equal to T ′ shown in FIG. 7 and the thickness of the fan portion. Even if T3 and the thickness T4 of the fan drive motor 20 are also set equal, the thickness of the communication path 17 can be T2 ′ larger than T2. In this way, the thickness of the communication path 17 is increased by inclining the distance between the bottom surface 39 of the fan 18 and the surface of the water tank 4 in the direction in which the front surface expands with respect to the central axis of the water tank 4. Since the area can be increased, the ventilation resistance can be reduced, which is desirable. When the above inclination direction is expressed by the relationship between the center axis of the water tank 4 and the center axis of the fan drive motor 20, the rotation axis of the fan drive motor 20 and the center axis of the water tank 4 are orthogonal to each other in the prior art shown in FIG. In the present invention shown in FIG. 8, the rotation axis of the fan drive motor 20 is inclined from a state orthogonal to the central axis of the water tank 4, and the inclination direction is behind the washing / drying machine body 1. It is slanting towards.

  Furthermore, the relationship between the external shape of the washing / drying machine main body 1 and the mounting form of the fan 18 will be described. 7 and 8, the relationship between the prior art and the arrangement of the fan 18 according to the present invention and the outer shape of the washing / drying machine main body 1 will be described. In FIG. 7A, when the washing / drying machine main body 1 is viewed from the direction orthogonal to the rotation axis of the water tub 4 and the direction orthogonal to the fan drive motor 20, the outer shape of the washing / drying machine main body 1 is an arc shape. The outer shape is a curved surface that envelops the corner 40 of the fan drive motor 20 and the fan 18 and the back end (right side in the drawing) of the water tank 4, and its radius is R1. Further, in FIG. 7B as viewed from the direction along the central axis of the water tank 4, the fan 18 is not directly above the water tank 4, and the gap space between the water tank 4 and the washing / drying machine main body 1 is large. It arrange | positions inclining only (PHI) of FIG. 9 mentioned later around the central axis of the water tank 4 so that it may arrange | position at the corner | angular part of a main body. When the outer shape of the washing and drying machine main body 1 is formed in an arc shape, the shape is a curved surface that envelops the fan drive motor 20 and the fan 18, and the radius thereof is R2. In FIG. 7B, the rotation axis of the fan drive motor 20 is shown as a vertical direction, but the washing and drying machine main body 1 is substantially square, so FIG. 7B is a fan at the corner of the washing and drying machine main body 1. The state where 18 is provided is shown.

  In FIG. 8A, the fan 18 is disposed with an inclination of Φ around the central axis of the water tank 4, and the fan 18 is disposed with an inclination of θ1 behind the washing / drying machine main body 1. The position 40 'closest to the rear end of the water tank can be arranged closer to the water tank 4 than shown in FIG. That is, assuming that the distance from the surface of the water tank 4 to the fan corner 40 in FIG. 7 is T5, the surface of the water tank 4 is arranged by tilting the fan by θ1 as shown in FIG. The distance T6 from the fan corner 40 'is smaller than T5. Since the position of the corner portion 40 ′ of the fan 18 is close to the surface of the water tank 4, when the outer shape of the washing and drying machine body 1 is an arc shape, the fan drive motor 20 and the corner portion 40 ′ of the fan 18 are connected to each other. It becomes an enveloped curved surface, and its radius is R1 ′. If the fan 18 and the fan drive motor 20 have the same dimensions, R1 ′> R1.

  When the state seen from the central axis direction of the water tank 4 is shown in FIG. 8B, since the fan 18 is inclined, the fan 18 and the fan drive motor 20 are projected in an elliptical shape. Since it becomes such a shape, when the outer shape of the washing and drying machine main body 1 is formed in an arc shape, the shape becomes a curved surface enveloping the shape in which the fan drive motor 20 and the fan 18 are projected in an ellipse, The radius is R2 ′, and if the fan 18 and the fan drive motor 20 have the same dimensions, R2 ′> R2.

  That is, the arc radius of the corner of the washer / dryer main body 1 can be increased by arranging the fan 18 inclined with respect to the water tank as in the present invention. realizable. Since the inner volume of the washer / dryer body 1 is smaller when the corner R is larger than the case where the outer shape of the washer / dryer body 1 is square, the size can be further reduced. Become.

  So far, the fan 18 has been described as being inclined with respect to the central axis of the water tank 4. Hereinafter, the arrangement of the drying means 11 including the fan 18 will be described. FIG. 9 is a view of the washing / drying machine main body 1 as viewed from the front of the washing / drying machine main body 1 along the center line direction of the water tank 4, and shows the layout relationship between the outer shape of the water tank 4 and the washing / drying machine main body 1 and the drying means 11. FIG. Since the washing / drying machine main body 1 has a substantially rectangular cross section and the water tank 4 has a substantially cylindrical shape, the drying means 11 is provided around the central axis of the water tank 4 at the corner that is the gap between the washing / drying machine main body 1 and the water tank 4. Is inclined with respect to the vertical axis by an angle Φ. The width W of the washing / drying machine main body is a dimension obtained by adding a gap larger than the amplitude at which the water tank 4 vibrates in the washing process or the dewatering process to the left and right sides of the water tank 4. The width W of the washing / drying machine is substantially determined by the size of the water tub 4, that is, the maximum mass of laundry that can be washed or dewatered, and cannot be reduced. The height H of the washing and drying machine main body 1 is a dimension obtained by adding h which is a margin dimension in the height direction to the apex on the central axis which is the maximum height portion of the water tank 4. In order to reduce the size by reducing the height H dimension of the washing / drying machine main body 1, it is desirable to make the h dimension as small as possible. Further, as described above, in order to reduce the volume of the washing / drying machine main body 1 and to reduce the size thereof, it is desirable that the corners have large arcs and the R is increased. In order to achieve such a configuration, as shown in FIG. 9, the region where the drying means 11 is arranged is formed in a shape sandwiched between the water tank 4 on the inner peripheral side and the R portion of the washing / drying machine main body 1 on the outer peripheral side. Is desirable.

  Next, the configuration of the drying means 11 according to the present invention will be described in more detail with reference to FIGS. FIG. 10 is a perspective view showing a state in which the drying means 11 is viewed from the inside of the water tank 4 in a direction along the rotation axis of the fan drive motor 20, and is illustrated as being transmitted through the drum 5 and the water tank 4. . That is, when the direction shown in FIG. 10 is shown in FIG. 2 to FIG. In FIG. 10, the direction of the front surface on the user side is the direction of the upper right arrow 35, and the lower left side of the drawing is the direction of the back surface. The lower right in the figure is the bottom surface side of the water tank 4, and the upper left is the direction of the upper surface. FIG. 11 is a perspective view showing a state viewed from the outside of the water tank 4 in the direction along the rotation axis of the fan drive motor 20 in the opposite direction to FIG. The direction of the arrow 35. In FIG. 11, the outer blades 19 and the heaters 21 provided on the inner side of the fan 18 are cut away from the outer case in the drawing direction so as to be shown. 12 is a cross-sectional view taken along line AA in FIG.

  The humid air inside the water tank 4 is exhausted in the direction of the arrow 42 from the exhaust port 12 provided at the lower back of the water tank 4, and the arrow 30 along the dehumidification duct 13 provided from the bottom to the top along the back of the water tank 4. As shown in FIG. For example, tap water (not shown) flows along the wall surface inside the dehumidifying duct 13 to cool and condense the humid air to dehumidify.

  In the vicinity of the upper surface of the water tank 4, the dehumidification duct is connected to a connection air passage 24 disposed substantially horizontally from the back surface to the front surface, and the dehumidified air is blown from the back surface to the front surface as indicated by an arrow 31. The The connection air passages 24 are arranged side by side in parallel along the circumference of the fan 18 and the water tank 4. A filter 16 is provided on the front side of the washing / drying machine body 1 connected to the connection air passage 24. The air that has passed through the connection air passage 24 is introduced into the filter 16 by changing its direction from the front direction to the substantially horizontal direction as indicated by an arrow 46. In the filter 16, lint that is lint contained in the blown air is collected by a mesh-like mesh filter described later, and clean air from which lint has been removed is discharged from the filter 16. The lower surface of the filter 16, that is, the surface closest to the water tank 4 is provided with a communication hole 43, and the air that has passed through the filter 16 is deflected in a direction close to the water tank 4 through the communication hole 43, It is introduced into the communication path 17. The communication passage 17 is provided between the filter 16 or the connection air passage 24 and the water tank 4 so as to overlap the filter 16 or the connection air passage 24, and the air is directed in the direction of the arrow 32 to the front side of the washing / drying machine main body 1. The air is blown from the rear side to the rear side. The communication path is connected to a surface of the fan 18 that is close to the water tank 4, and air is introduced into the fan 18 by rotation of the rotary blade 19 from a fan inlet hole 44 that is disposed concentrically with the rotary blade 19 that is open to the fan 18. Suction is caused by the negative pressure generated. As described above, the fan 18 and the connection air passage 24 are arranged side by side in parallel, and at the same time, the communication passage 17 is provided between the fan 18 and the water tank 4 so as to overlap the fan 18. Yes. The rotary blade 19 built in the fan 18 is rotated by the fan drive motor 20, and is sucked into the center of the rotary shaft of the rotary blade 19 from the fan inlet hole 44 opened in the fan 18, and centrifugal force is applied from the outer periphery of the rotary blade 19. It is accelerated and discharged. The accelerated and discharged air is blown along the arrow 33 to the heater 21 disposed on the front side of the washing / drying machine main body 1 with respect to the fan 18. The heater 21 is a so-called PTC heater, for example, and has self-temperature controllability. This self-temperature controllability is a characteristic that prevents the temperature from increasing excessively when the temperature rises and the resistance increases rapidly. The air that has passed through the heater 21 is heated to, for example, about 100 ° C. and becomes dry hot air. The warm air is guided to the blow bellows 25 from the blow duct 22 arranged in the vicinity of the front surface of the washing / drying machine main body 1 according to the arrow 34. The blow bellows 25 is connected to a blow opening 23 provided at the front edge of the water tub 4, and warm air is introduced into the water tub 4 from the blow opening 23 and blown into the drum 5 so that the laundry 14 Allow the water to evaporate and dry.

  Here, the relationship among the filter 16, the fan 18, the communication path 17, and the outer shape of the washing / drying machine main body 1 will be described with reference to FIG. 13. FIG. 13 is a schematic view seen from the front side of the washing and drying machine main body 1 along the central axis of the water tank 4, and is a view seen from the side substantially opposite to the cross-sectional view shown in FIG. As described above with reference to FIG. 8, the fan 18 is disposed so as to be inclined with respect to the central axis of the water tank 4 by an angle θ <b> 1. Further, as shown in FIGS. 10 to 12, the fan 18 is arranged side by side and in parallel with the connection air passage 24 connecting the dehumidification duct 13 to the filter 16, and the fan 18 and the connection air passage 24 are further connected to the filter. A communication path 17 connecting between 16 and the fan 18 is disposed between the water tank 4. A gap T1 is provided between the communication passage 17 and the water tank 4 so as not to collide with the water tank 4 when the water tank 4 vibrates while the drum is rotating in a washing process or a dewatering process.

  Here, as shown in FIGS. 12 to 13, since the communication passage 17 is connected to the fan inlet hole 44, it is necessary to increase the cross-sectional area of the communication passage 17 in order to reduce the ventilation resistance. . Here, the communication passage 17 connects the filter opening 29 and the fan inlet hole 44, and the fan inlet hole 44 opens at the bottom surface of the fan 18 closest to the water tank 4. It is effective to incline toward the passage 17. That is, as shown in FIG. 13, it is assumed that the center of the fan inlet hole 44 is disposed at a position inclined by φ with respect to the vertical axis around the central axis of the water tank 4. If the central axis is inclined by φ2 larger than φ, the distance between the bottom surface of the fan 18 and the water tank 4 is 49A on the side close to the communication path 17, that is, the side close to the connection air passage 24, and the fan. Since the distance 49B on the far side from the communication path 17 opposite to the communication path 17 is 49A> 49B, the cross-sectional area of the communication path 17 connected to the fan inlet hole 44 can be increased, so It is preferable because the resistance is reduced. That is, since the fan 18 is inclined with respect to the water tank 4, the communication passage 17 is arranged so that the air flows from the direction in which the distance between the fan inlet hole 44 and the water tank 4 increases to the direction in which the distance decreases. By connecting with the fan inlet hole 44, the cross-sectional area of the air flow path can be increased and the ventilation resistance can be reduced.

  An air flow path for flowing air in the direction of arrow 31 from the dehumidification duct 13 via the connection air passage 24 to the filter 16 and an air flow for flowing air from the fan 18 via the heater 21 to the blowing duct 22 Since the path is arranged side by side substantially in parallel along the circumferential surface of the water tank 4, the L dimension shown in FIGS. 3 and 4 which is the dimension of the drying means 11 in the direction of the rotation axis of the water tank 4 can be shortened. The depth of the washing / drying machine main body 1 can be reduced, which is effective for downsizing.

  Furthermore, since the filter 16 is provided on the front surface of the washing / drying machine main body 1 close to the opening 6 of the water tank 4, it is preferable because the filter 16 can be easily taken out and cleaned.

<Filter configuration>
Next, the configuration of the filter 16 will be described with reference to FIG. 12, FIG. 14, and FIG. FIG. 14 and FIG. 15 are diagrams showing the detailed configuration of the filter 16 and show a state where the user has pulled out the filter 16 in the direction of the arrow 35 from the filter take-out hole 50 and removed it. Here, the filter take-out hole 50 opens in the front surface of the washing / drying machine main body 1. The filter case 47 is formed continuously from the connection air passage 24 and is configured to accommodate the filter 16. The filter 16 includes a filter frame 26 and a handle 27 that is grasped when the user pulls out the filter 16. The filter frame 26 has a dimensional relationship in which the width dimension F1 on the near side pulled out by the user is larger than the width dimension F2 on the far side. It is said. Here, since the front dimension F1 is larger than the rear dimension F2, when the user pulls out the filter 16 in the direction of the arrow 35 for cleaning, the filter frame 26 and the filter are simply pulled out. Since the gap between the case 47 and the case 47 is opened, the filter 16 can be easily pulled out in the direction of the arrow 35. On the other hand, when the removed filter 16 is fitted into the filter case 47 again, the tip portion having a small width F2 opposite to the handle 27 is fitted into the filter case 47 from the filter take-out hole 50 and the arrow 35 The filter frame 26 is gradually guided inside the filter case 47 by being pushed in the opposite direction, and the filter frame 26 is fitted inside the filter case 47 by being pushed all the way into the filter case 47. As described above, the dimensional relationship of F1> F2 is preferable because the filter 16 is easily guided to the filter case 47 when the filter 16 is fitted.

  When the filter 16 is fitted into the filter case 47, a flexible sealing material 28 made of rubber, for example, provided between the handle of the filter 16 and the filter frame 26 is provided between the filter case 47 and the filter 16. As a configuration for closing the air, air is prevented from leaking outside through the gap.

  The filter 16 includes a filter opening 29 on a side surface that is a part of the filter frame 26 and is located on one side between the front side of the width F1 and the back side of the width F2 and close to the connection air passage 24. Is connected to the connection air passage 24 when fitted to the filter frame 47, and the air passes through the filter opening 29 from the connection air passage 24 as indicated by an arrow 31, and the inside of the filter 16. Flow into. Here, if the length of the side surface where the filter opening 29 is opened is F3, F3 is a dimension in the depth direction of the washing / drying machine main body 1, and therefore, it can be made larger than the width F1, and thus configured. This is preferable because the area of the filter opening 29 can be enlarged to reduce the ventilation resistance.

  A first filter 37 connected to the filter opening 29 and formed of a fine mesh mesh is provided in a bag shape, and the first filter 37 is a fiber contained in the air flowing from the filter opening 29. It is the structure which can collect lint which is litter. The air that has passed through the first filter 37 is discharged in a direction that changes to the direction of the arrow 32 that is close to the water tank 4. The air discharged from the filter 16 in the direction of the arrow 32 passes through the communication hole 43 provided in the filter case 47 and is blown toward the communication path 17. Here, a second filter 38 made of a mesh-like mesh is provided in the communication hole, and lint that could not be collected by the first filter 37 is collected.

  Here, when the filter 16 is pulled out in the direction of the arrow 35, the second filter 38 is provided in the vicinity of the filter extraction hole 50, so that there is an advantage that it is easy to clean from the filter extraction hole 50. Furthermore, since the second filter 38 is provided in the communication hole 43, foreign matter can be removed from the communication hole 43 when the filter 16 is being removed and cleaned or when the filter 16 is fitted into the filter case 47. 17 is suitable because it is not dropped.

  Here, as described with reference to FIGS. 10 to 12, the connection air passage 24 communicating with the filter case 47 is disposed side by side in parallel on the outer periphery of the fan 18 or the heater 21 and the water tank 4. It is desirable that the shape is a shape in which the side opposite to the filter opening 29 where the fan 18 or the heater 21 is disposed escapes. Furthermore, since the blow duct 22 is provided on the lower side of the handle between the handle 27 and the water tank 4, the waste space of the drying means 11 can be reduced and the device can be mounted in a small size. This is suitable for downsizing the machine body 1.

  As described above, according to the present invention, the fan is disposed to be inclined around the rotation axis of the water tank, and is located in the front-rear direction with respect to the water tank, and the direction between the fan and the water tank is washed and dried. By making the front side of the machine body wider than the back side, it is preferable because the area of the flow path flowing into the fan from the front side can be expanded and the ventilation resistance can be reduced.

  In addition, the fan is located at the corner of the washer / dryer body, and the motor is placed outside to enter a small space, and the corner of the washer / dryer body can be made into a larger arc shape. There is an effect that it is suitable for downsizing.

  Furthermore, the air flow path from the dehumidification duct to the filter via the connection air passage and the air flow path from the fan to the blowing duct via the heater are substantially parallel along the circumferential surface of the water tank. Since the dimensions of the drying means in the direction of the water tank rotation axis can be shortened, the depth dimension of the washing / drying machine main body can be reduced, and there is an effect that it is suitable for downsizing.
