Description

  The present invention relates to a drum-type washing and drying machine that performs washing, rinsing, dehydration, and drying steps in a rotating drum that is rotatably supported in a water tank in a horizontal direction or in a direction inclined from the horizontal direction.

  Such a drum type washing and drying machine will be described with reference to the drum type washing and drying machine 1 according to the embodiment of the present invention shown in FIG. The rotating drum 2 is provided in the water tank 3 and generally performs washing, rinsing and dewatering processes by controlling the water supply, drainage and rotation of the rotating drum 2 in the water tank 3, and is a blowing means. The drying process of the laundry is carried out by circulating the air in the water tank 3 through the circulation blowing path 5 provided with the dehumidifying means and the heating means by the blower fan 15 (see, for example, Patent Documents 1 and 2). ).

  Here, the dehumidifying means and the heating means are an evaporator and a condenser constituting an air conditioner connected by a compressor and a refrigerant circuit as an example, and the evaporator introduces the air in the water tank to the circulation air flow path by the air blowing means. And heat exchange through the condenser sequentially to make thirsty hot air heated after dehumidification, so that it can be efficiently dried repeatedly by blowing it into the water tank and exposing it to the laundry in the rotating drum Yes.

  Foreign matter such as lint separated from the laundry in the rotating drum is mixed in the circulating air circulating through the circulating air passage in this drying process, and this clogs the evaporator and condenser, or in the bearing part of the air blowing means. Biting or depositing on each part of the air blowing means causes malfunction. For this reason, the filter which collects a foreign material is provided in the middle of the circulation ventilation path | route as disclosed by patent document 1,2. In many cases, as disclosed in Patent Document 1, this filter is provided on the upstream side of the air blowing means, the dehumidifying means, and the heating means in the circulating air introduction pipe for introducing the circulating air from the drum and the water tank. However, Patent Document 2 adopts a condensing method by injecting cooling water into the dehumidifying means so that the foreign matter can be humidified and dropped simultaneously with the dehumidification of the circulating air. The structure arrange | positioned in this order is disclosed.

In any case, the filter is provided so that it can be attached and detached because foreign matter to be collected accumulates and the passage resistance of the circulating air increases. Patent document 1 is disclosing the filter directly attached and detached from the attachment / detachment opening of the front surface of a washing-drying machine main body with the top plate which block | closes this attachment / detachment opening. Further, Patent Document 2 discloses a heating / filter unit in which a heating unit and a filter chamber are integrated with a lid opened through a loading / unloading port provided on the top surface of the washing / drying machine. A removable filter is disclosed.
JP-A-8-243292 Japanese Patent Laid-Open No. 2002-200395

  However, the filter described in Patent Document 1 has a lid plate and a detachable knob projecting in the immediate vicinity of the opening for putting in and out the laundry in the main body of the washing / drying machine. There is a concern that the foreign matter that has been used without being noticed of looseness and has passed through the filter part may be clogged in the dehumidifying means downstream.

  In addition, the filter described in Patent Document 2 is a lid plate that is relatively high in the washing / drying machine main body and is detachable on the top surface that is hard to be caught by people, and the outlet is flush with the top surface. Since the filter is located inside the lid plate, it will not get loose due to inadvertent catching. However, to attach and remove the filter, open the lid of the attachment / detachment opening on the top surface of the washing / drying machine, which is relatively high and difficult to perform by hand, and grasp the filter knob located behind the attachment / detachment opening by hand. It must be lifted and difficult to work. Further, since the filter is attached and detached in the vertical direction on the top surface of the relatively tall washing and drying machine main body, it is easy to work forward and it is difficult to attach and remove smoothly. Furthermore, as described in Patent Document 2, the opposite rims of the heating / filter unit attaching / detaching port are provided with convex shapes opposite to each other to prevent the filter from being loosened. In the configuration employing the engagement / disengagement structure in which the engagement pieces facing each other elastically engage with each other, it is not easy to attach and detach the filter with the engagement / disengagement resistance with a small knob.

  Therefore, the present applicant attaches and detaches the filter through the attachment / detachment port on the top surface, thereby making it easy to avoid inadvertent catching, and allowing the filter chamber to be opened / removed so that the filter can be simply attached / detached. The idea is proposed separately.

  However, as the present inventor further advanced the technical development for the practical use of this technology, the filter chamber and the top plate of the washer / dryer main body easily attach and detach the center of the filter chamber and the filter chamber easily. In some cases, it was not easy to attach to and remove from the filter chamber, or it was difficult to attach to the filter chamber. As a result of various investigations, the filter chamber is located below the top plate, so it is fixed to the housing in advance of the top plate, and the top plate is placed over the top plate and fixed to the housing. Therefore, the dimensional accuracy between the fixed position of the filter chamber to the housing and the fixed position of the upper surface plate, the forming accuracy from the center position of the filter chamber to the mounting portion, and the mounting position from the center position of the upper surface plate attachment / detachment port It has been found that the center deviation tends to occur due to the influence of the molding accuracy up to, and the center deviation cannot be completely eliminated. To cope with this problem, if the fitting of the filter into the filter opening and the filter chamber is made loose, the necessary positioning and seal between the filter and the filter chamber become sweet, and circulating air leaks, especially foreign matter such as lint. Although we may invite a speech balloon, we have now been able to propose a technology that can handle such problems without any problems.

  In view of the above points, the object of the present invention is to easily avoid inadvertent catching on the top surface, and to simply attach and detach the filter to the filter chamber where the upper end opening opens from the top surface attachment / detachment port. Another object of the present invention is to provide a drum-type washing and drying machine that can be easily centered between the filter chamber and the filter chamber.

  In order to achieve the above object, according to the present invention, a rotating drum is formed in a water tub in which a large number of through holes are formed and accommodates laundry, and the water supply, drainage and rotation of the rotating drum in the water tub are provided. The washing, rinsing, and dehydration processes are carried out under the control of the laundry, and the drying process of the laundry is carried out by circulating the air in the water tank through the circulation blowing path provided with the dehumidifying means and the heating means by the blowing means. In a drum-type washing / drying machine having a filter chamber in which a filter that mainly collects foreign matter such as lint is detachable in the middle of the ventilation path, the filter is attached to the top surface of the washing / drying machine main body. It is possible to detachably attach to the filter chamber from the degassing opening, and the detachable opening is provided on a part of the top plate fixed to the casing constituting the washing and drying machine main body to form the top surface. At any direction you can also move temporarily placed state around the center of the, as one characterized by being adapted to the fixed centering relative to the mounting port of the upper plate.

  According to such a configuration, in order to collect the foreign matter such as lint by passing the circulating air circulating through the circulating fan path in the drying process through the filter mounted in the filter chamber in the middle of the circulating fan path, Satisfying conditions that make it easier to avoid people getting caught and loosened by attaching and detaching on the top of the washing and drying machine main body that is relatively tall, and on the top of the washing and drying machine body It can be simply attached / detached from above into the filter chamber in which the upper end opening opens from the opened attachment / detachment opening. In particular, although the filter chamber is supported prior to the top plate with respect to the housing, it is temporarily placed so that it can move in any direction around the center, and subsequently the top plate is supported by the housing. Regardless of whether the fixing to the housing is performed prior to the fixing of the filter chamber, the filter chamber can be moved in any direction around the center by utilizing the fact that the filter chamber can be moved to the side of the filter chamber with respect to the attachment / detachment opening of the top plate. The center of the filter chamber and the top plate can be completely and accurately centered without any interference between the two parties, and the filter chamber and the top plate can be fixed. There is no resistance or hindrance such as catching, hitting and dripping on the simple attachment / detachment of the filter.

  The present invention is also characterized in that, for one feature, the filter can be attached to and detached from the filter chamber from an attachment / detachment opening opened on the top surface of the washing / drying machine body, and the attachment / detachment opening is attached to the attachment / detachment opening when attached to the filter chamber. A top plate that fits and closes, and the attachment / detachment opening is provided on a part of the top plate fixed to the casing constituting the main body of the washing and drying machine, and the filter chamber is centered on the casing. Another feature is that it is temporarily placed in a state in which it can move in any direction around it, and is centered with respect to the attachment / detachment opening of the upper surface plate to be permanently fixed.

  According to such a configuration, in particular, the filter chamber is supported prior to the upper surface plate with respect to the housing, but is kept in a temporarily placed state in which it can move in any direction around the center. Regardless of whether the fixing to the housing is performed prior to the fixing of the filter chamber to support the face plate to the housing, the filter plate can be moved in any direction around the center to The filter chamber side can be centered with high accuracy and accuracy without any interference between the two sides with respect to the attachment / detachment port to complete the fixing of the filter chamber and the top plate, and play between the filter and the filter chamber can be suppressed. The filter can be easily attached to and removed from the filter chamber through the attachment / detachment opening, and there is no resistance or obstruction such as hitting or twisting. The filter top plate can be accurately centered on the attachment / detachment opening by attaching the filter. Thus interference and bias AER fitted without.

According to a further configuration, the filter chamber is provided in a filter unit having an auxiliary part such as a connection part with the circulation air flow path, and is temporarily placed in a housing by this filter unit.
A filter unit having an additional part such as a connecting part between the filter chamber and the circulation air passage of the filter chamber is taller than a single filter chamber and has a large number of overhangs, thereby forming the outline of the washing and drying machine main body. It becomes easy to place temporarily on a large housing stably.

According to a further configuration, the attachment / detachment port and the filter chamber have a positioning inner peripheral surface for centering each other by a positioning jig inserted from above.
It is possible to move by fitting a positioning jig having a shape that fits the positioning inner peripheral surface from above, to the positioning inner peripheral surface for centering each other in the mounting opening and the filter chamber. The positioning inner peripheral surface on the filter chamber side can be forcibly centered with respect to the positioning inner peripheral surface on the mounting port side, and the filter chamber side can be centered on the mounting port side.

In a further configuration, the positioning inner circumferential surface is located in front of and behind the filter in the attachment / detachment direction substantially along the outer surface of the attached filter.
By simply attaching the positioning jig to the attachment / detachment port and the filter chamber in the filter mounting direction, the positioning jig fits in the positioning inner peripheral surface of the attachment / detachment port and the positioning inner peripheral surface of the filter chamber with no play in order. Centering that meets the conditions for attaching and detaching the filter is achieved.

The lower surface of the upper surface plate around the attachment / detachment opening is received with a gap that regulates the range of movement of the filter chamber around the upper end opening portion where the filter of the filter chamber enters and exits when the upper surface plate is temporarily placed in the housing. According to a further configuration with a guide part,
In order to cover the upper surface plate on the filter chamber temporarily placed on the housing and to center the filter chamber or to fix the housing to the housing, the attachment / detachment opening of the upper surface plate at the time of covering is attached to the filter chamber. In the process of bringing the upper end opening closer to the center alignment, the upper end opening of the filter chamber is temporarily positioned between the guide portions, and the filter chamber is positioned relative to the attachment / detachment opening when the positioning jig is fitted. It is possible to avoid the centering operation from being hindered due to a large center swing and a catch or hit.

According to a further configuration, the guide portion is a vertically-oriented convex rib along the attachment / detachment direction of the filter.
The filter chamber can be guided with respect to the attachment / detachment opening of the top plate with a very small guide area without being caught.

According to a further configuration, the convex ribs facing each other have a shape in which the amount of movement restriction relative to the upper end opening of the filter chamber between them decreases from the receiving start point of the upper end opening toward the receiving end point or in the vicinity thereof. If
When the upper plate is put on the filter chamber in the temporarily placed state, the guide portion fits the upper end opening of the filter chamber and easily accepts the movement restriction amount with a large margin at the initial stage. It is possible to guide without difficulty to the fitting end point.

The main fixing of the filter chamber is performed by fastening with screws with respect to the upper surface plate from above.
The filter chamber in a temporarily placed state centered with respect to the attachment / detachment opening of the upper surface plate fixed on the housing and positioned below the upper surface plate is fastened with screws from above the upper surface plate, and the upper surface plate is attached to the housing. Can be fixed to the book.

According to a further configuration, the fastening between the filter chamber and the upper surface plate is performed by screwing a screw into the boss portion provided in the filter chamber from above through an attachment hole provided in the upper surface plate.
The centering of the filter chamber with respect to the attachment / detachment opening of the top plate makes the mounting hole of the top plate and the boss part of the filter chamber face each other, and attaches the screw while easily seeing this through the shallow mounting hole of the plate thickness of the top plate The filter chamber can be fastened to the upper surface plate by screwing into the boss portion from the hole and securing a sufficient screwing amount using the boss portion.

The main fixing of the filter chamber is, according to a further configuration involving pinching when the top plate is fastened to the housing with screws from above.
By using the clamping force generated between the top plate and the housing when the top plate is fastened and fixed to the housing with screws, the filter chamber is directly or indirectly sandwiched and permanently fixed. It is possible to reduce or eliminate the number of permanent fixing points by fastening the screws.

According to a further configuration, the fastening between the housing and the upper surface plate is performed by screwing a screw from above into a screw hole provided in the housing through an attachment hole provided in the upper surface plate.
Screw the screw from the mounting hole to the screw hole and make sure that the top plate is aligned with the mounting hole and the screw hole of the housing. The top plate can be fastened to the housing using strength.

According to a further configuration, the mounting hole is provided at a position that is not hidden by a positioning jig that centers the top plate and the filter chamber.
Since the mounting hole is in a position that is not hidden with respect to the positioning jig centering the filter chamber with respect to the attachment / detachment opening of the upper surface plate, the positioning jig centers the filter chamber with respect to the attachment / detachment opening of the upper surface plate. As it is, fastening from above to the upper surface plate of the filter chamber through the mounting hole and fastening from above to the housing of the upper surface plate can be performed.

  According to the present invention, the filter is attached and detached on the top surface of the relatively tall washing / drying machine main body, and it is easy to avoid a person and the like from being inadvertently caught and loosened. It can be easily and easily attached and detached directly from above into the filter chamber having the upper end opening. In addition, using the fact that the filter chamber can be temporarily placed in the housing and moved in any direction around the center, the filter chamber can be attached to the attachment / detachment opening of the top plate that covers the filter chamber and is fixed to the housing. The filter chamber and the top plate can be fixed accurately and reliably with only the two parties, and the positional relationship and seal that prevent play and vibration required for both sides can be secured by suppressing play between the filter and the filter chamber. Thus, simple attachment / detachment to / from the filter chamber through the attachment / detachment port of the filter can be easily performed without causing resistance and obstruction such as hitting and dripping.

  1 and 2 according to the embodiment of the present invention, the water tank 3 is suspended in a suspended state by a suspension structure (not shown) in the main body 44 of the washer / dryer, and the water tank 3 has a bottom. 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. A clothing doorway 11 leading to the opening end of the rotary drum 2 is formed on the front side of the water tank 3, and a door 9 that closes the opening provided on the upward inclined surface formed on the front side of the washing and drying machine main body 44 so as to be openable and closable. 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 rotating 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. Further, a water injection pipe 12 and a drain pipe 13 are connected to the water tank 3, and water is poured into and drained into the water tank 3 by control of a water injection valve and a drain valve (not shown).

  When the door 9 is opened and laundry and detergent are put into the rotating drum 2 to start the operation of the drum-type washing / drying machine 1, a predetermined amount of water is injected into the water tank 3 from the water injection pipe 12. As a result, 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. Also in this rinsing step, the laundry stored in the rotary drum 2 is rinsed by repeating the stirring operation in which the laundry is lifted by the stirring protrusion by the rotation of the rotary drum 2 and dropped.

  The drum-type washing / drying machine 1 has a function of drying laundry stored in the rotary drum 2. The air in the water tank 3 as shown in FIGS. 1 and 2 is exhausted to dehumidify and heat. The circulation air flow path 5 described above for blowing the dried air into the water tank 3 again is formed. As described above, it is general that a dehumidifying means such as an evaporator 31, a heating means such as a condenser 32, and a blower fan 15 as a blowing means are provided in the middle of the circulating air flow path 5 as shown in FIG. 1. By rotating and driving the blower fan 15, air in the circulation blower path 5 is generated and the air in the rotary drum 2 containing the laundry flows from the water tank 3 to the blower fan 15 through the through holes 8. The air is exhausted to the circulating air introduction pipe 16 and dehumidified by dehydrating the evaporator 31 located upstream of the blower fan 15 and heated by heat exchange with the condenser 32, and is always dry. Of air. This dried high-temperature air is sent from the blower fan 15 to the blower duct 33 to the water tank 3 and blown into the water tank 3. The high-temperature dry air blown into the water tank 3 enters the rotary drum 2 through the through holes 8 and escapes to the water tank 3 while being exposed to laundry such as clothes, and is again introduced into the circulating air introduction pipe line 16. The drying process is carried out by repeating the circulation of the air in the circulating air flow path 5 described above.

  Further, in the drying process using the circulating air flow path 5, foreign matter such as lint generated from laundry such as clothes is circulated in the air circulated through the circulating air flow path 5, and the evaporator 31 and the condensation are circulated. It is difficult to carry out a drying process such as clogging of the vessel 32, biting into the rotating part of the blower fan 15, and accumulation on the inner surface of the blower fan 15, and frequent troublesome maintenance is required. In the middle of the circulating air flow path 5, as an example, the upstream side of the evaporator 31, the condenser 32, and the blower fan 15, and therefore in the middle of the circulating air introduction conduit 16 as shown in FIG. It is common to provide a filter chamber 36 that houses a main filter 35 that removes water. As a result, even if foreign matter is mixed into the air after the laundry is dried and introduced into the circulating air introduction pipe 16 side on the evaporator 31 side, it is collected by the main filter 35 when passing through the filter chamber 36. And is not mixed into the circulating air downstream. Therefore, the functions of the evaporator 31, the condenser 32, and the blower fan 15 are maintained for a long time. On the other hand, however, there is a problem in that the collected foreign matter accumulates on the main filter 35 in the filter chamber 36, and the passage resistance of the circulating air gradually increases, thereby lowering the drying function. Is provided so as to be detachable as described in Patent Documents 1 and 2 described above.

  The evaporator 31 and the condenser 32 are handled as an air conditioner 39 as shown in FIG. 1 housed in one container 38 together with a compressor 37 connected by a refrigerant circuit for circulating a refrigerant therethrough. The air inlet 41 side of the blower fan 15 is coupled to the exhaust port 41 side for exhausting air after dehumidifying and heating the introduced air of 39 with a vibration-proof structure portion between them and integrated. As a result, the compressor 37, the evaporator 31, and the condenser 32 are combined into a container body 38, and the two air conditioners 39 and the blower fan 15 are combined into a single unit suitable for mass production. Thus, each of the four devices, that is, the compressor 37, the evaporator 31, the condenser 32, and the blower fan 15 is related as an air conditioning / blower unit 81 that forms a part of the circulation blower path 5 and achieves a predetermined function.

  In the present embodiment, in order to solve the problems such as those described in Patent Documents 1 and 2, the filter 91 typified by the main filter 35 is provided in the washing / drying machine main body 44 in order to provide the main filter 35. From the attachment / detachment port 51 shown in FIGS. 1 and 3 to 5 opened in the top surface 44a, the filter chamber 36 is attached / detached through an attachment / detachment path 52 inclined forward from the lower part to the upper part. In this way, the circulating air circulating through the circulation air passage 5 in the drying process is passed through the main filter 35 attached to the filter chamber 36 in the middle of the circulation air passage 5 to collect foreign matters such as lint. The main filter 35 satisfies the condition that it is easy to avoid a person or the like from being inadvertently caught and loosened by attaching and detaching the main filter 35 at the top surface 44a of the relatively tall washing and drying machine main body 44, and washing. What attaches easily to the front and rear components of the attachment / detachment force from the attachment / detachment opening 51 opened on the top surface 44a of the dryer main body 44 through a vertical attachment / detachment route such as that described in Patent Document 2. Compared to the above, it can be smoothly attached and detached without difficulty in the direction along the attaching / detaching path 52 inclined forward from the lower part to the upper part where it is difficult to bend. For this purpose, it is preferable that the filter chamber 36 that follows from the attachment / detachment port 51 can be guided by the attachment / detachment path 52 that is inclined over the entire attachment / detachment stroke of the main filter 35 to a predetermined position.

  Further, as shown in FIGS. 2, 3, 5, 7, and 8, the main filter 35 has a top plate 53 that closes the attachment / detachment port 51. It is assumed that a cue recess 56 having a lid 55 that pushes upward from above is provided. Thus, by attaching the main filter 35 through the attachment / detachment opening 51, the attachment / detachment opening 51 is finally closed by the top plate 53 so that the appearance is substantially flush as shown in the figure. Can be more easily caught, and can be pulled out and attached stably by placing a finger on the hand-carrying recess 56 provided on the top plate 53. Since the clasp recess 56 is always closed by the lid 55 on which the closing spring 54 works, the clasp recess 56 is unlikely to cause inadvertent catching by a person or the like. Since the lid 55 is pushed open by the applying operation, the main filter 35 can be easily and easily attached and detached by placing fingers with no special work. In addition, the cue recessed portion 56 forms a rearward cue edge 56a that puts a finger on the front part of the opening, and this cue edge 56a is located in the front-rear direction of the top board 53 in the center or slightly closer to the front. In order to hang a finger on the clasp recess 56, a clasp edge 56a facing backward is provided at the front portion of the opening, so that the arm extends from the front onto the top surface 44a of the washer / dryer main body 44 and the clasp recess The main filter 35 can be pulled out easily and reliably by the natural action of inserting and folding the finger into the hand 56 and without slipping, and along the outer surface of the finger and the top plate 53 hooked on the hand edge 56a. Holding the top filter 53 between the palm and holding the main filter 35 stably, handling such as carrying after drawing and mounting to the filter chamber 36 can be performed easily and stably. . Further, since the rear portion of the lid 55 is hingedly connected to the rear portion of the opening of the handle recess 56 by a hinge pin 57, the handle edge 56a is opened by pushing the lid 55 open when the finger is put into the handle recess 56, and the finger is left as it is. Therefore, it is possible to easily perform the finger-hanging operation on the cue recess 56 for attaching and detaching and the cue edge 56a with a continuous behavior.

  More specifically, as shown in FIGS. 5, 7, and 8, the main filter 35 is formed by supporting a main filter material 79 on a main support frame 71 that is integrally formed or connected so as to extend downward from the top plate 53. A seal packing 73 made of silicon rubber or the like is attached to the outer periphery of the lower portion of the top plate 53 of the main support frame 71 so as to be positioned inside the circulating air discharge port 72 shown in FIG. When the seal packing 73 is mounted at a predetermined position, the seal packing 73 is pressed against the stepped portion 74 on the inner periphery of the attachment / detachment port 51 to seal the filter chamber 36, and the main filter 35 and the filter chamber 36 are sealed. An elastic engagement portion 75 as shown in FIGS. 8 and 9 that engages elastically when the main filter 35 is mounted at a predetermined position is provided therebetween. As a result, the main support frame 71 extending downward from the top plate 53 is inserted into the filter chamber 36 with the main filter material 79 only by attaching the main filter 35 to the filter chamber 36 so as to block the attachment / detachment port 51 with the top plate 53. The seal packing 73 provided on the outer periphery of the lower portion of the top plate 53 of the main support frame 71 at a predetermined mounting position is pressed against the inner peripheral step 74 inside the attachment / detachment port 51 and the elastic engagement portion 75 is elastic. The filter chamber 36 is maintained in a sealed state by the engagement, and the main filter material 79 can be correctly positioned inside the circulating air outlet 72 of the filter chamber 36. The mounting portion of the seal packing 73 of the main support frame 71 is a flange portion 71a facing the step portion 74 of the filter chamber 36, and the seal packing 73 extends from the mounting portion 73a to the flange portion 71a and presses against the step portion 74. Because of the relationship having the lip 73b, the seal packing 73 is firmly backed up by the flange portion 71a of the main support frame 71 so that the seal lip 73b is well adapted to the entire circumference of the inner peripheral step 74 inside the attachment / detachment port 51. It is possible to ensure press contact and prevent air leakage. Further, since the mounting portion 73a is reinforced by the backup of the flange portion 71a, a thin one is sufficient. Here, the attachment / detachment opening 51 is formed on the upper surface plate 44b forming the top surface 44a of the washing / drying machine main body 44, whereas the stepped portion 74 for sealing the filter chamber 36 with the seal packing 73 is directly below the attachment / detachment opening. It is formed on the inner periphery of the opening 36d of the filter chamber 36 that is positioned and supported.

  As shown in FIGS. 3 to 5 and 9, the attachment / detachment opening 51 opened to the upper surface plate 44 b has a dam portion 44 c rising from the top surface 44 a on the entire periphery, and the main filter 35 mounted inside the dam portion 44 c. It is assumed that a concave portion 44d for fitting the top plate 53 is provided. As a result, the top plate 53 does not protrude from the concave portion 44d alone to the top surface 44a so that a person or the like is not caught, and even if a little water spills on the top surface 44a, the top plate 53 is dammed by the dam portion 44c. It is possible to prevent entry into the outlet 51 and prevent damage to the electrical equipment in the washing / drying machine main body 44. Further, the top plate 53 has a convex wall 53a projecting downward on the outer periphery, and the concave portion 44d is a fitting that serves as a seal to receive the convex wall 53a between the peripheral wall 44e and the upward convex portion 44f of the inner periphery. It has a structure to receive the top plate 53. Even if water enters the attachment / detachment port 51, the sealing function by the seal fitting structure with the top plate 53 in the recess 44d is provided. It is possible to prevent the inside of the attachment / detachment port 51 from extending, and further safety of the electrical equipment can be achieved. Furthermore, the top plate 53 is made slightly lower than the dam portion 44c. As a result, even when water reaches the weir portion 44c, it is possible to suppress the wetting and shifting to the top plate 53 side that has dropped due to the surface tension of the water, and this also increases the safety of the electrical equipment.

  However, if water that spills over the dam 44c spills around the detachable port 51, it easily reaches between the dam 44c and the top plate 53 and easily enters the filter chamber 36 from the detachable port 51. The board 53 prevents the water from entering the filter chamber 36 through the attachment / detachment port 51 by covering the attachment / detachment port 51 and the seal-indicating structure between the attachment / detachment port 51, but water spills on the top plate 53. Then, water easily enters the filter chamber 36 through the attachment / detachment port 51.

  If water enters the filter chamber 36, it may be damaged by the blower fan 15, which is an electrical equipment that has a problem with water, through the circulation blower passage 5, or a heater that is not employed in this example. Therefore, in the present embodiment, the filter chamber 36 further introduces circulating air provided below the opening 36d based on the condition that the upper opening 36d where the main filter 35 enters and exits opens to the attachment / detachment port 51. The water reservoir 141 as shown in FIGS. 1, 5, and 6 is provided, which is lower than the circulating air inlet 78 that is to be introduced and the circulating air outlet 72 that is to discharge the introduced circulating air through the main filter 35. Thus, the main filter 35 is easy to avoid a person or the like from being inadvertently caught and loosened, and the filter chamber in which the opening 36d is opened from the attachment / detachment opening 51 of the top surface 44a in the washing / drying machine main body 44. The filter chamber 36 satisfies the condition that it can be easily and easily attached / detached directly from above into the inside 36, and the opening 36d of the filter chamber 36 is open to the attachment / detachment opening 51, so that the top surface 44a and the top plate 53 can be connected. Even if water falls through the attachment / detachment port 51, the water reservoir 141 is located lower than the circulating air inlet 78 and the circulating air outlet 72 provided below the opening 36 d at the upper end of the filter chamber 36. Since it is easy to be carried down and stored there, it is possible to reduce the probability that a lot of intrusion water will spread to other places in the circulation air flow path 5, and the electric equipment outside the circulation air flow path 5 It is possible to avoid the span at things like harm to.

  Here, as shown in FIGS. 5 and 6, the water reservoir 141 is the entire bottom portion between the front wall where the circulating air introduction port 78 of the filter chamber 36 is provided and the rear wall where the circulating air discharge port 72 is provided. There is. In this way, the total capacity of the circulating air introduction space for the filter chamber 36 to introduce the circulating air from the circulating air inlet 78 and discharge it from the circulating air outlet 72 through the main filter 35 and the accommodation space of the main filter 35. A relatively large amount of intrusion water can be stored in the water reservoir 141 that uses the size of the bottom that meets the requirements.

  Further, as described above, the circulating air introduction port 78 and the circulating air discharge port 72 satisfy the positional relationship in which they do not face each other as shown in FIGS. Even if water enters the filter chamber 36 and is blown away by the circulating air introduced from the circulating air inlet 78 in the drying process in which the circulating air is circulated, the introduced circulating air enters the circulating air inlet 78. Since it does not go straight to the circulating air discharge port 72 which is not facing, but goes along a curved path as shown by the arrow shown in FIG. 5 or the arrow 172 shown in FIG. The liquid is separated and remains in the filter chamber 36 and is easily stored in the water reservoir 141.

  Further, as described above, the main filter 35 supports the main filter material 79 on the bowl-shaped main support frame 71 extending downward substantially along the inner surface of the filter chamber 36 from the top plate 53 and circulates the filter chamber 36. By being configured to be located inside the air discharge port 72, the main support frame 71 has a bowl shape and is positioned substantially along the inner surface of the filter chamber 36. In addition to being smoothly discharged to the circulating air discharge port 72 through the main filter material 79 introduced and supported inside the circulating air discharge port 72, the filter chamber 36 is fully discharged. This is advantageous in that it is easy to form the water reservoir 141 having the required size without much volume expansion by utilizing the size of the water reservoir 141.

  As shown in FIG. 9, the elastic engagement portion 75 is a combination of an engagement recess or an engagement hole 75a shown in the drawing and a resin spring 75b as shown in the drawing, and the resin spring 75b is detachable. Thereby, the elastic engagement portion 75 can be easily engaged with and disengaged from the engagement hole 75a when the main filter 35 is attached / detached by utilizing the soft elasticity of the resin spring 75b, and does not particularly interfere with the attachment / detachment of the main filter 35. Then, it is possible to notify the user of the completion of the mounting and the start of the removal with a click feeling or a clicking sound that elastically engages at the end of the mounting and at the initial stage of the removal, and the elastic engagement is released. Moreover, the resin spring 75b is fixed at both ends and has an engaging portion 75b1 bent in a mountain shape in the attaching / detaching direction of the main filter 35 that engages with the engaging hole 75a between the both ends, so that the tension force is slightly increased. At the same time, it has high durability. The angle of the resin spring 75b is such that the rising angle in the mounting direction of the main filter 35 is larger than the rising angle in the pulling direction, and it is on the attachment / detachment path 52 to the engagement hole 75a immediately after the mounting of the main filter 35 is completed. Since the step 75a1 and the side with the higher rising angle begin to engage and the mounting resistance is slightly increased, the mounting can be terminated while the user senses that the mounting is nearing completion. In addition, there is a relation that the main filter 35 is not inadvertently detached by attaching / detaching through the upward attaching / detaching opening 51, and at the initial drawing out of the main filter 35, the main hole 35 is connected to the main hole 35a from the engagement hole 75a on the small rising angle side. Applying a smaller resistance than when the filter 35 is completely attached and allowing the user to feel that the extraction has started, while allowing the user to experience a pull-out state without resistance due to disengagement due to the disengagement. become. In addition, the resin spring 75b is easily broken, but can be replaced independently, so that it can be easily and inexpensively handled. For this purpose, the resin spring 75b is provided on the main support frame 71 side of the main filter 35 as shown in FIGS. 8 and 9, and is exposed to the outside of the main support frame 71 when the main filter 35 is pulled out. Easy to replace. For this replacement, two resin springs 75b are integrally formed on the left and right sides of the back portion of the box body 76 opened forward, and the box body 76 is fitted to the back portion of the main support frame 71 on the opening side. The screw 77 shown in FIG. 9 is screwed to be detachable. Correspondingly, the engagement hole 75 a is provided on the back wall side of the attachment / detachment path 52, and the main filter 35 to be attached / detached slides with the elastic engagement portion 75 positioned on the front wall of the attachment / detachment path 52. At this time, it is possible to prevent the resin spring 75b from being slidably brought into contact with the front wall of the attachment / detachment path 52 within a range where the resin spring 75b is not required.

  The main support frame 71 has a bowl shape as shown in FIGS. 5, 7, and 8 substantially along the inner surface of the filter chamber 36, and the filter chamber shown in FIGS. 5 and 6 below the mounting portion of the seal packing 73. The main filter material corresponding to the upper half 71b that introduces the circulating air from the circulating air inlet 78 provided in the upper half 36b of the 36 and the circulating air outlet 72 provided in the lower half 36c of the filter chamber 36. It has a lower half 71c supporting 79. As a result, the main support frame 71 has a bowl shape and is positioned so as to be substantially along the inner surface of the filter chamber 36, and the upper half corresponding to the circulating air introduction port 78 provided in the upper half 36 b of the filter chamber 36. Circulating air is introduced into the portion 71 b and led to the lower half portion 71 c supporting the main filter material 79 inside the circulating air discharge port 72 in the lower half portion 36 c of the filter chamber 36 and circulated through the main filter material 79. The air can be smoothly discharged to the air discharge port 72 by using the full size of the filter chamber 36.

  Here, the main support frame 71 is shown in FIGS. 5 and 7, and as described above, the upper half 71b for introducing the circulating air from the circulating air introduction port 78 provided in the upper half 36b of the filter chamber 36; And the lower half portion 71c supporting the main filter material 79 corresponding to the circulating air discharge port 72 provided in the lower half portion 36c of the filter chamber 36, thereby allowing the filter chamber 36 to pass through the circulating air introduction port 78. FIG. 5 shows that the circulating air is introduced into the upper half portions 36b and 71b of the main support frame 71 and the filter chamber 36 and the lower half portions 36c and 71c of the main support frame 71 are spread at least vertically. The air is smoothly discharged from the circulating air discharge port 72 with gas-liquid separation along a curved path as indicated by an arrow. In addition, as indicated by the arrows in FIG. 6 and as described above, the circulating air introduction port 78 and the circulating air discharge port 72 are also shifted in the left-right direction, so that they are introduced from the circulating air introduction port 78 into the filter chamber 36. The circulating air is smoothly discharged toward the circulating air discharge port 72 with gas-liquid separation in a curved path that also uses the left and right expansion of the filter chamber 36, so that the filter chamber 36 is expanded vertically and horizontally. The gas-liquid separation function can be enhanced by the use of the curved long path.

  In addition, as long as the main filter material 79 is not hung on the circulating air inlet 78 and is not bypassed as necessary, the main filter material 79 is not limited to the range corresponding to the circulating air outlet 72, but as shown in FIG. The area of the filter chamber 36 can be used to provide the main filter material 79 in a wide area outside 72 and to pass the circulating air toward the circulating air discharge port 72 as indicated by an arrow in the figure. As a result, clogging is less likely to occur due to an increase in the circulating air passage area of the main filter material 79.

  In this case, both the filter chamber 36 and the main filter 35 attached thereto are inclined as shown in FIG. 1, and the attachment / detachment port 51 formed on the upper surface plate 44 b of the washing / drying machine main body 44 with the inner surface of the filter chamber 36. An attachment / detachment path 52 leading to is formed.

  Moreover, as shown in FIGS. 5 and 7, the filter 91 of the present embodiment works first against the circulating air that enters from the circulating air inlet 78 of the filter chamber 36 and is discharged to the circulating air outlet 72. The above-described main filter 35 has a double filter structure with a backup filter 82 that operates thereafter. The backup filter 82 is mounted before the main filter 35 and is taken out later. The main filter 35 is extracted from the backup filter 82. Are attached to be removed later, and the finger is applied to the front wall from the inside for the purpose of taking out the backup filter 82 from the lower half 36c, which is the back side of the filter chamber 36. A cue recess 133 is provided to which the The backup filter 82 is attached to the filter chamber 36 only by sliding it from above, and is guided to a predetermined position by the attachment / detachment path 52.

  For this purpose, a backup filter 82 having a bowl-shaped sub-support frame 101 along the inner surface of the lower half 36c of the filter chamber 36 in the backup filter 82 around the lower half 71c of the main support frame 71 in the main filter 35 is provided. The sub filter material 83 is supported outside the main filter material 79 so as to cover it. Thus, after the backup filter 82 is attached to the lower half 36c of the filter chamber 36, the main filter 35 is attached to the inside of the upper half 36b of the filter chamber 36 and the subsequent backup filter 82 and introduced into the filter chamber 36. The circulating air can satisfy the double filter structure that passes through the main filter material 79 of the main filter 35 and the sub-filter material 83 of the backup filter 82 and passes through the circulating air discharge port 72. As a result, foreign matters such as fine lint are reliably collected by the main filter material 79 and the sub filter material 83 which are thin and have low air resistance, so that the functions of the devices such as the evaporator 31, the condenser 32 and the blower fan 15 are collected. Therefore, since most foreign matters are collected by the main filter material 79 that passes first, clogging frequently occurs on the side of the main filter material 79, and on the side of the sub filter material 83. The number of clogging is extremely less than that of the main filter material 79.

  Therefore, when the main filter 35 and the backup filter 82 are attached, the main filter 35 leaves the backup filter 82 in the lower half portion 36c of the filter chamber 36 and pulls it out first, so that the backup filter 82 is frequently clogged. The backup filter 82 can be easily attached and reattached, and the backup filter 82 is pulled out after the main filter 35 only when clogging processing is necessary, and the main filter 35 is attached after the clogging processing is performed prior to the main filter 35. It returns to the use state by attaching. Therefore, handling is not particularly troublesome.

  Corresponding to such a double filter structure of the main filter 35 and the backup filter 82, the backup filter 82 includes a circulating air outlet of the backup filter 82 and the filter chamber 36 as shown in FIGS. A seal made of silicon rubber or the like that seals both a partition boundary 92 having an independent exhaust space 95 on the 72 side and a partition boundary 93 having an independent exhaust space 96 between the main filter 35 and the backup filter 82. A packing 94 is provided. Accordingly, the circulating air introduced into the filter chamber 36 and the upper half 71b of the main support frame 71 is not bypassed, and the independent exhaust space 96 between the main filter 35 and the backup filter 82, the backup filter 82, and the filter chamber 36. As shown by the arrows in FIG. 5, the independent exhaust space 95 between the circulating air discharge port 72 and the circulating air discharge port 72 is sequentially passed through to the circulation air discharge port 72 after removing the foreign matter of the double filter structure.

  Here, as shown in FIG. 5, the backup filter 82 has a sub-support frame 101 having a bowl shape that fits into the lower half portion 36c provided with the circulating air discharge port 72 of the filter chamber 36, and is circulated. The sub-filter material 83 is supported inside the air discharge port 72, and the main filter 35 has a bowl shape substantially along the inner surface of the backup filter 82 mounted on the upper half 36b and the lower half 36c of the filter chamber 36. An auxiliary filter that is supported by an upper half 71 b that introduces circulating air from a circulating air inlet 78 provided in the upper half 36 b of the filter chamber 36 and a backup filter 82 that is attached to the lower half 36 c of the filter chamber 36. A main support frame 71 having a lower half portion 71c that supports the main filter material 79 on the inner side of the material 83 and discharges circulating air in a double filter structure with the backup filter 82. To satisfies the antecedent relationship of the discharge circulating air to the front-rear relationship and removable work.

  The seal packing 94 is attached to the outer periphery of the sub-support frame 101 as shown in FIGS. 5, 7, and 9, and the upper half 36b and the lower half of the filter chamber 36 are shown in FIGS. Circulating air exhaust formed on the outer surface between the stepped portion 102 formed on the inner surface between the portion 36c and facing the circulating air introduction port 78 and the upper half 71b and the lower half 71c of the main support frame 71. By sandwiching the main filter 35 and the backup filter 82 by mounting the filter chamber 36 in a predetermined position between the facing portions of the step portion 103 facing the outlet 72 side, both the step portions 102 and 103 are pressed against and sealed. Like to do. Accordingly, the two partition boundary portions 92 and 93 can be sealed by using one seal packing 94 by using the fitting of the main filter 35 and the backup filter 82 to the filter chamber 36. The main filter 35 is held by an elastic engagement portion 75 that elastically engages when the filter chamber 36 is mounted at a predetermined position, and is prevented from inadvertently loosening and causing air leakage. Moreover, as shown in FIGS. 5, 7, and 9, the seal packing 94 is mounted on the flange portion 101a facing the both step portions 102 and 103 of the sub-support frame 101, and from the mounting portion 94a to the flange portion 101a. As shown in FIGS. 5 and 7, seal lips 94 b and 94 c extending to both the step portions 102 and 103 are pressed against the step portions 102 and 103. As a result, the seal packing 94 is firmly backed up by the flange portion 101a of the sub-support frame 101, and the seal lips 94b and 94c are well fitted to the entire circumference of both step portions 102 and 103, so that air leakage does not occur. Can be.

  Further, as shown in FIG. 7, the main filter 35 and the backup filter 82 are provided with magnets 111 and 112, respectively, and the filter chamber 36 is provided with the main filter 35 and the backup filter 82 as shown in FIG. When mounted at a position, it includes a filter detection device 113 having a built-in pair of filter detection switches that individually react with the magnets 111 and 112 and output an electric signal to the outside. As a result, if both the main filter 35 and the backup filter 82 are not mounted under the control of the control board 67 provided inside the operation panel 66, the use can be prohibited. Since the attachment / detachment opening 51 such as the main filter 35 is located on the top surface 44a of the washing / drying machine main body 44, the operation panel 66 is not obstructed by the attachment / detachment opening 51 on the front surface of the washing / drying machine main body 44. As shown, it can be provided widely, and even if there are many operation units and display units corresponding to multiple functions, it is easy to operate and easy to see.

  Here, the main filter 35 includes a top plate 53 that closes the attachment / detachment opening 51 when mounted in the filter chamber 36, and a magnet 111. The filter chamber 36 is connected to the magnet 111 when the main filter 35 is mounted at a predetermined position. A filter detection device 113 having a built-in filter detection switch that reacts oppositely and outputs an electrical signal is provided. The main filter 35 is attached or not attached to the magnet 111 on the main filter 35 side and the filter chamber 36 side. Since the electrical signal corresponding to the detection by the filter detection device 113 is output to the outside, the main filter 35 can be used for the control for prohibiting the use of the drum type washing and drying machine 1 in the unmounted state. To prevent the use of the attachment / detachment port 51 in an unfavorable condition where the attachment / detachment port 51 is not covered with the top plate 53 capable of preventing a large amount of water from entering. It can be.

  Further, as shown in FIG. 7, the main filter 35 is circulated having an open state opening 121 through which circulating air is introduced from a circulating air introduction port 78 provided in the upper half 36 b on the filter insertion side of the filter chamber 36. Circulating air discharge supporting the main filter material 79 corresponding to the circulating air discharge port 72 provided in the upper half 71b on the air introduction side and the lower half 36c on the back side of the filter chamber 36 as described above. A main support frame 71 having a lower half 71c on the side is provided, and an upper half 71b on the circulating air introduction side of the main support frame 71 is indicated by a solid line arrow 122 through the opening 121 from the circulating air introduction port 78. The negative pressure region 124 that receives suction as indicated by the broken arrow 123 by the flow of the circulating air that is introduced and discharged to the circulating air discharge port 72 through the main filter material 79 is provided in the external discharge port 127. 5, and communicates through the external exhaust communication port 128b for exposing the external exhaust path 128 communicating with the external exhaust port 128a shown in FIG. 6 in the filter chamber 36.

  Although the outside air introduction path 125 is normally closed with a built-in electromagnetic valve 132, the electromagnetic valve 132 is opened by control from the control board 67 or the like when the upper limit temperature of the circulating drum 2 or circulating air is detected. Thus, outside air is sucked into the circulating air by the negative pressure suction force generated in the negative pressure region 124 by the flow of the circulating air, and is mixed with the circulating air that circulates in the circulating air discharge path 72 toward the circulating air discharge port 72. The temperature of the rotary drum 2 and the circulating air can be lowered and kept in an appropriate temperature range, and therefore the electromagnetic valve 132 is often kept open thereafter. Further, when the amount of circulating air becomes excessive due to the introduction of this external air or the like, the pressure in the circulating air blowing path 5 rises. It enters the exhaust path 128 and exits from the external exhaust port 128a. As shown in FIGS. 2 and 6, the outside air introduction port 125a is opened right behind so that no foreign matter or the like falls, whereas the external exhaust port 128a is opened upward as shown in FIG. Moreover, as shown in FIG. 1, the washing and drying machine main body 44 protrudes from the back surface 44 g. As a result, the moist circulating air before dehumidification is exhausted from the external exhaust port 128a to prevent dripping of condensate water, and a small amount of dew condensation water is allowed to dry naturally.

  Here, the filter chamber 36 is formed such that a circulating air introduction port 78 is formed on the front wall of the upper half portion 36b on the side of the attachment / detachment port 51, and an external exhaust communication port 128b is formed on the rear wall so as to face each other. A circulating air discharge port 72 is formed at a position on the rear side wall of the lower half portion 36c that is the back side and is laterally removed below the external exhaust communication port 128b. Thus, excess circulating air is introduced from the circulating air introduction port 78 in the front wall of the upper half 36b of the filter chamber 36 into the circulating air introduction area 126 of the upper half 71b of the main support frame 71, and then the filter The chamber 36 is pushed out without difficulty so as to go straight to the external exhaust communication port 128b in the rear wall of the upper half portion 36b of the chamber 36 and exhausted to the outside. The remaining circulating air with the normal air volume is smoothly discharged toward the circulating air discharge port 72 on the rear wall in the lower half 36c of the filter chamber 36.

  As shown in FIGS. 5 and 8, the external exhaust communication port 128 b is sufficiently smaller than the circulation air discharge port 72, and the circulation is adjusted by adjusting the ventilation resistance between the external exhaust communication port 128 b and the circulation air discharge port 72. Priority is given to the discharge of air to the circulating air discharge port 72 to prevent the circulating air from being accidentally escaped to the outside. Further, as shown in FIG. 7, the negative pressure region 124 is juxtaposed with the circulating air introduction region 126 in the upper half 71 b on the circulating air introduction side of the main support frame 71, and the backup filter 82 of the main support frame 71. A space unrelated to each other is used to satisfy the required size. Specifically, the negative pressure region 124 is formed by partitioning from a wider circulating air introduction region 126 by a plate-like partition part 131 integrally formed in the upper half 71b on the circulating air introduction side of the main support frame 71. In addition, the circulating air introduction area 126 is connected to the circulating air discharge side. As a result, the circulating air introduction area 126 and the negative pressure area 124 are arranged in parallel with a very simple structure, and the negative air pressure area 124 is sucked by the flow of the circulating air flowing from the circulating air introduction area 126 to the circulation air discharge port 72. Can be covered. As shown in FIG. 7, the outside air introduction path 125 is opened through the intake port 124 a in the peripheral wall portion facing the partition portion 131 in the negative pressure region 124. As a result, the outside air indicated by the broken arrow 123 drawn into the negative pressure region 124 through the outside air introduction port 125a, the outside air introduction path 125, the outside air introduction communication port 125b, and the intake port 124a collides with the partition 131 and is directly below the filter chamber. 36, the circulating air introduced from the circulating air introduction port 78 of the filter chamber 36 into the circulating air introduction region 126 formed by the upper half 71b of the main support frame 71 is directed toward the lower half 71c. Thus, the flow toward the circulating air discharge port 72 of the filter chamber 36 is smoothly merged and mixed, and the flow of the circulating air indicated by the solid arrow 122 is not disturbed, and the flow of the circulating air indicated by the solid arrow 122 is negative. It is easy to apply a suction force to the pressure region 124, and the outside air sucked there as indicated by a broken line arrow 123 is directed toward the circulating air discharge port 72 of the filter chamber 36. To satisfy the easy relationship.

  On the other hand, when the main filter 35, the backup filter 82, and the auxiliary filter 129 are clogged in the drying process, there is no escape route for the circulating air introduced to the main filter 35 in the past, and the pressure in the circulating air passage 5 increases. Then, it leaks into a drain hose (not shown) connected to the aquarium 3, and the water trapped in the drain trap is blown by the wind pressure, so that the function of the trap is destroyed and the odor from the sewer pipe leaks. However, the excess amount of circulating air at the time of such clogging is reversed from the negative pressure region 124 as shown by a one-dot chain line arrow 134 in FIG. 7 contrary to the flow so far (broken line arrow 123 in FIG. 7). The air enters the outside air introduction path 125 where the electromagnetic valve 132 is opened through the outside air introduction communication port 125b through the outside air inlet 124a and exits from the outside air introduction port 125a. In, can do is possible to eliminate the naturally boost.

  Further, the negative pressure region 124 of the upper half 71b on the circulating air introduction side of the main support frame 71 is opened to the front together with the circulating air introduction region 126 having the open opening 121 as shown in FIGS. Then, the upper half 36b on the filter attachment / detachment side of the filter chamber 36 is closed by a portion without the circulating air introduction port 78 on the front wall as shown in FIG. As a result, both the circulating air introduction area 126 and the negative pressure area 124 in the upper half 71b of the main support frame 71 are opened to form a simple shape that functions together with the filter chamber 36, thereby facilitating molding.

  By the way, as already described, the filter 91 is simply passed from the attachment / detachment opening 51 opened on the upper surface plate 44b forming the top surface 44a of the washing / drying machine main body 44 to the filter chamber 36 where the upper opening 36d is opened. Although it can be attached / detached, in order to satisfy the positional relationship and seal required for the attachment / detachment port 51 and the filter chamber 36, they need to be properly centered. The detachable port 51 is used to detach from the filter chamber 36 from the detachable port 51 opened on the top surface 44a of the washer / dryer main body 44, as represented by the main filter 35 that fits along the entire inner surface. 10 and FIG. 15 constituting the washing / drying machine main body 44. In the relationship provided in a part of the upper surface plate 44b which forms the top surface 44a and is fixed to the casing 151 as shown in FIG. 10 is centered as shown in FIGS. 12 to 15 with respect to the attachment / detachment opening 51 of the upper surface plate 44b in a temporarily placed state that can move in any direction around the center on the housing 151 as shown in FIG. The book is fixed.

  Thus, although the filter chamber 36 supports the casing 151 in advance of the upper surface plate 44b, the filter chamber 36 is set in a temporarily placed state in which it can move in any direction around the center. Regardless of whether the fixing to the housing 151 is performed prior to the fixing of the filter chamber 36 to support the body 151, the upper surface plate is utilized by utilizing the fact that the filter chamber 36 can move in any direction around the center. The filter chamber 36 and the upper surface plate 44b can be completely fixed by accurately centering the filter chamber 36 side with respect to the attachment / detachment port 51 of 44b with just two persons and without any other obstacles. Even if the play between the main filter 35 and the filter chamber 36 is simply attached to and detached from the filter chamber 36 through the attachment / detachment port 51, there is no resistance or obstruction such as hitting or dripping. The things. Therefore, the play between the main filter 35 and the filter chamber 36 is suppressed to prevent the play and vibration necessary for both sides and the seal is secured, and the filter chamber 36 is connected to the filter chamber 36 through the attachment / detachment port 51 of the main filter 35. Simple attachment and detachment can be easily performed without the resistance and obstruction of hitting and dripping.

  Moreover, as shown in FIGS. 3 and 5, the main filter 35 includes a top plate 53 that fits and closes the attachment / detachment port 51 when fitted to the filter chamber 36 as described above. The centering of the attachment / detachment port 51 and the filter chamber 36 allows the attachment / detachment port 51 to be fitted to the attachment / detachment port 51 with high accuracy without interference or bias when the main filter 35 is completely attached to the filter chamber 36. Therefore, it is advantageous for the water intrusion prevention function described above, and the appearance can be adjusted so that the gap between the attachment / detachment port 51 and the top plate 53 is constant over the entire circumference, and the top plate 53 with respect to the attachment / detachment port 51. There is no so-called chattering noise that occurs when the proximity portion due to the bias is in contact with each other by vibration.

  As described above, the filter chamber 36 is a filter having an auxiliary portion such as a connection portion with the circulation air passage 5, an outside air introduction passage 125, an external exhaust passage 128, etc., as shown in FIGS. 1, 5, 6, and 10. It is provided in the unit 152, and is temporarily placed in the housing 151 by the filter unit 152 as shown in FIG. Specifically, a hook 36e formed at the front part of the opening 36d of the filter chamber 36 is hung from above with play on the upward flange 151a1 of the front upper beam 151a in the casing 151 which is a metal frame, The placement piece 36f extending to the right side of the filter chamber 36 is placed on the right upper beam 151b in the casing 151, the outside air introduction port 125a of the outside air introduction path 125, and the outside exhaust port of the outside exhaust path 128. This is achieved by fitting the 128a portion into the through holes 151c1 and 151c2 of the rear upper beam 151c in the housing 151 with play. However, such a temporary placement state may be realized in any way. In this way, the filter unit 152 having the filter chamber 36 and the attached portion is larger than the filter chamber 36 alone, and uses a large number of overhanging portions, so that the outline of the washing / drying machine main body 44 is formed. Thus, the filter chamber 36 can be stably and temporarily placed on the strong casing 151.

  The attachment / detachment port 51 and the filter chamber 36 have positioning inner peripheral surfaces 51g and 36g for centering each other by a positioning jig 153 inserted from above as shown in FIGS. It is assumed that Specifically, the opening edge of the attachment / detachment port 51 is used as the positioning inner peripheral surface 51g, and the inner peripheral surface of the stepped portion 74 of the filter chamber 36 is used as the positioning inner peripheral surface 36g. As described above, the positioning inner peripheral surfaces 51g and 36g provided in the attachment / detachment port 51 and the filter chamber 36 for centering each other have a shape suitable for the positioning inner peripheral surfaces 51g and 36g. The positioning inner peripheral surface 36g on the filter chamber 36 side that can move around the center is fitted to the positioning inner peripheral surface 51g on the attachment / detachment port 51 side by fitting a positioning jig 153 as shown in FIG. Centering is forcibly performed, and the filter chamber 36 side can be centered on the attachment / detachment port 51 side, and the positioning inner peripheral surfaces 51g, 36g are substantially on the outer surface of the main filter 35 mounted as shown in the figure. Accordingly, the positioning jig 153 is attached to the attachment / detachment opening 51 and the filter chamber 36 by mounting the main filter 35 on the attachment / detachment port 51 and the filter chamber 36. By simply mounting in the direction, the positioning jig 153 fits into the positioning inner peripheral surface 51g of the attachment / detachment port 51 and the positioning inner peripheral surface 36g of the filter chamber 36 without any play in order, Centering that meets the conditions for attaching and detaching the main filter 35 is achieved. Moreover, the positioning legs 153a are inserted as a substantially straight simple shape of the positioning jig 153 by arranging both of the positioning inner peripheral surfaces 51g and 36g so as to be substantially flush with the attaching / detaching direction of the main filter 35. Centering is possible just by doing. The positioning jig 153 has a head 153b that protrudes in a flange shape around the positioning leg 153a at the upper end of the positioning leg 153a, and the head 153b fits into the recess 44d of the attachment / detachment port 51. In this state, the centering is completed by making the contact state, thereby making it easy to prevent a centering failure. Further, the positioning inner peripheral surfaces 51g and 36g are arranged so as to be flush with each other on the tapered surface tapered toward the mounting direction side of the main filter 35, and the positioning leg portion 153a of the positioning jig 153 also corresponds to this. It has a tapered outer peripheral surface that can be easily fitted and removed for positioning.
