Therefore, quietness can be ensured.

  In the drum type washing / drying machine 1 shown in FIG. 1 according to the embodiment of the present invention, the water tank 3 is suspended in the washing / drying machine main body 44 by a suspension structure (not shown), and the water tank 3 has a bottomed cylindrical shape. The formed rotating drum 2 is disposed such that its axial direction is 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 performed without bending, and the workability of the drum-type washing and drying machine for taking in and out the laundry from the opening in the horizontal direction is generally provided. The badness of 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 a stirring operation in which the laundry is lifted and dropped by a stirring protrusion (not shown) by the rotation of the rotary drum 2.

  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. In general, as described above, 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. 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 dehydrated by dehydrating the evaporator 31 located upstream of the blower fan 15 and heated by heat exchange with the condenser 32 that is heated to about 65 ° C. With that, it is always dry and hot 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 circulation air passage 5, foreign matter such as lint generated from laundry such as clothes is circulated in the air circulated through the circulation air passage 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. From the middle of the circulating air flow path 5, specifically, the upstream side of the evaporator 31, the condenser 32, and the blower fan 15, and accordingly, in the middle of the circulating air introduction pipe line 16 as shown in FIGS. It is common to provide a filter chamber 36 that houses a filter 35 that removes foreign substances in the circulating air. Thus, 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 filter 35 when passing through the filter chamber 36. , It will not be 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. However, on the other hand, the collected foreign matter accumulates on the filter 35 in the filter chamber 36, and there is a problem that the passage resistance of the circulating air gradually increases and the drying function is deteriorated. It is provided so as to be detachable as in the case of.

  In the present embodiment, the air as shown in FIGS. 3 and 4 in which the evaporator 31 and the condenser 32 and the compressor 37 connected to each other by a refrigerant circuit that circulates the refrigerant are accommodated in one container 38. As shown in FIG. 5, the anti-vibration structure 43 between the blower fan 15 and the exhaust port 41 side which is handled as the conditioner 39 and exhausts after dehumidifying and heating the air introduced into the air conditioner 39 is shown. Are combined 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 for mass production. Thus, the four devices, that is, the compressor 37, the evaporator 31, the condenser 32, and the blower fan 15 are related to each other so as to form a part of the circulation blower path 5 and achieve a predetermined function.

  As a result, the assembling structure and work for associating the four necessary devices are simplified, which is an element of cost reduction. In addition, the whole is not bulky, the refrigerant circuit length and the circulation air passage length are both shortened, it is easy to handle and can contribute to space saving, and the thermal efficiency of both the dehumidifying and heating system and the drying system is improved. Moreover, if the air conditioner 39 is installed in the washing / drying machine main body 44 as shown in FIGS. 1 and 2, it is not necessary to directly install and support the blower fan 15 integrated in the washing / drying machine main body 44. Since stable installation is possible, the installation structure and operation are simplified, which is also an element of cost reduction. In addition, the integration of the air conditioner 39 and the blower fan 15 has two vibration sources of the compressor 37 and the blower fan 15 together, but the blower fan 15 and the air conditioner 39 are mutually connected. The vibration isolation structure 43 prevents both vibrations from affecting each other, does not resonate, and also exhibits a vibration absorbing action on the blower fan 15 itself. Vibration can be reduced, and quietness can be ensured.

  The specific structure of the coupling between the air conditioner 39 and the blower fan 15 is, for example, made of silicon between the exhaust port 41 of the air conditioner 39 and the intake port 42 of the blower fan 15 as shown in FIGS. A seal structure 45 sandwiching a packing 45a and the like, and between the plurality of locations outside the seal structure 45, specifically, between the three locations shown in FIG. It has a portion 43 and is fastened and coupled so as to be separable. Thus, the air conditioner 39 and the blower fan 15 only have the seal structure 45 between the exhaust port 41 and the intake port 42, and satisfy the sealing performance by fastening between a plurality of locations around the outside. They are connected to each other, and the fastening is used to provide an anti-vibration structure, thereby obtaining an anti-vibration action between them. Further, the air conditioner 39 and the blower fan 15 can be separated with the disassembly of the seal structure 45 and the vibration isolation structure 43 simply by releasing the fastening, which is convenient for assembly and disassembly and is convenient for maintenance.

  The fastening between the air conditioner 39 and the blower fan 15 will be described in more detail. The fastening seats facing each other as shown in FIGS. 4 and 5 at the plurality of fastening points of the air conditioner 39 and the blower fan 15. One of 39a and 15a, specifically, the convex shaft 39b provided in the facing direction to the fastening seat 39a on the air conditioner 39 side, and the other, specifically, the fastening provided on the fastening seat 15a of the blower fan 15 A fitting structure with the hole 15b and a screw 48 from the washer 46 side between the washer 46 applied to the opposite side of the fastening seat 15a having the fastening hole 15b and the convex shaft 39b are tightened with screws 48. The fastening seats 39a and 15a have a fastening structure for fastening the opposing portions. Corresponding to such a fastening structure, the anti-vibration structure 43 includes the fitting portion between the convex shaft 39b and the fastening hole 15b, between the opposing portions of the fastening seats 39a and 15a, and the fastening portion. An anti-vibration member 47 made of butylene rubber or the like is interposed between the fastening seat 15a having the hole 15b and the washer 46.

  As a result, the fitting structure of the fastening shaft 39b and the fastening hole 15b between the fastening seats 39a and 15a to which the air conditioner 39 and the blower fan 15 are fastened, and the insertion of the vibration isolating member 47 between the fitting portions. An elastic support action with little radial escape by the vibration isolating member 47 using pressure, a fastening structure and a fastening seat 15a having a fastening hole 15b and a washer 15a and a washer having a fastening hole 15b between the fastening seats 39a and 15a to be fastened. Due to the elastic support action with little axial escape by the vibration isolating member 47 using the fastening pressure between the air conditioner 46 and the air conditioner 39 and the blower fan 15, the vibration isolating member 47 can mutually vibrate in any direction. Since transmission is cut off and vibration is absorbed by the blower fan 15, effective vibration isolation can be achieved.

  The vibration isolating member 47 has a shape as shown in FIG. 6, and as shown in FIG. 5, a cylindrical portion 47a located between the fitting portions of the fastening hole 15b and the convex shaft 39b, and both end portions of the cylindrical portion 47a. Rubber molded integrally having two flange portions 47b and 47c located between the opposing portions of both fastening seats 39a and 15a and extending between the fastening seats 15a and the washers 46 having the fastening holes 15b. As a product. Therefore, between the shaft hole fitting portions in the fitting structure of the fastening seats 39a and 15a fastened by one vibration isolating member 47, the cylinder portion 47a is provided between the fastening seats 39a and 15a and the fastening seat 15a in the fastening structure. Between the washers 46, flanges 47b and 47c at both ends of the cylindrical portion 47a are positioned to perform the vibration-proofing action, and from one of the fastening holes 15b of the fastening seat 15a to one of the vibration-proofing members 47. As described above, an effective mutual vibration isolating action and a vibration absorbing action for the blower fan 15 can be obtained by simply mounting the flange portion 47c and the like while diving it to the other side.

  One of the two flange portions 47b and 47c is configured as shown in FIG. 5 in which one of the two flange portions 47b and 47c extends radially at a plurality of locations in the circumferential direction, and the fastening hole 15b is formed on the side of the plurality of flange portions 47c projecting radially. It becomes easy to hide in. In the specific examples shown in FIGS. 4 and 5, the air conditioner 39 and the continuous flange portion 47 b are located between the facing portions of the fastening seats 39 a and 15 a and the flange portion 47 c divided in the circumferential direction is located. The direct vibration isolation between the blower fans 15 is enhanced.

  Furthermore, the air conditioner 39 has the compressor 37 fixed to the bottom wall 38a of the container body 38 so as to be separable with a vibration isolating structure 51 therebetween. In this case, the compressor 37 becomes a heavy vibration source, but the bottom wall 38a is stably connected to the bottom wall 38a that is stably installed in the main body 44 of the air conditioner. The anti-vibration action by the anti-vibration structure 51 between the fixed parts is obtained, and the vibration of the compressor 37 is prevented from being transmitted to the other part of the container 38 and the washing / drying machine main body 44 side. However, a vibration absorbing action also acts on the compressor 37 itself. Further, with such a configuration, it is possible to prevent the problem that the vibration of the blower fan 15 and the vibration of the compressor 37 resonate, resulting in large vibration and noise. Accordingly, the silent performance is further improved. It is preferable that the vibration isolation structure 51 also adopts the same method as the vibration isolation structure 43 of the fastening portion between the air conditioner 39 and the blower fan 15 described above.

  Further, as described above, the air conditioner 39 and the blower fan 15 can be handled as a low-volume air conditioning / blower unit by mutual integration, and the above-described axis is changed from the rear to the front as shown in FIGS. The back surface 3a of the water tank 3 and the bottom 44a and the back part 44b of the washing / drying machine main body 44 are inclined so that the axis is raised from the rear part to the front part. The air conditioner 39 and the blower fan 15 can be easily separated without any interference even if the installation height exceeds the lowest height of the aquarium using the space S1 that is substantially triangular between the wall and the wall. Assembling structure and work that function only by connecting the circulating air passage 5 to the circulating air introduction pipe 16 side and the air duct 33 side are simplified.

  Further, the blower fan 15 has an upward exhaust port 15c on the back side thereof, and around the motor 7 that drives the rotary drum 2 protruding from the rear surface 3a of the water tank 3 through the blower duct 33 extending upward from the exhaust port 15c. Since it is connected to the back surface 3a of the water tank 3 on the upper side of the motor 7, the air-conditioning / blower unit 39 arranges the evaporator 31 and the condenser 32 close to each other as shown in FIG. Even if the depth dimension is slightly larger than the compressor 37 juxtaposed to the left and right from the form of shortening the length, the water tank 3 extends from the upward exhaust port 15c located on the back side of the blower fan 15. The occupant space is required via the motor 7 protruding from the back surface 3a of the water tank 3 with the air duct 33 leading to the upper part of the back surface rising along the back 44b of the washing and drying machine main body 44. Without bulk low short as possible piping.

  At the same time, the air conditioner 39 has an upward circulating air introduction port 39c on the back side of the end opposite to the blower fan 15, and the circulating air introduction line 16 extending upward from the circulating air introduction port 39c As shown in FIG. 1, the filter chamber 36 described above is arranged so that the filter 35 can be attached and detached from the attachment / detachment port 44d of the top 44c of the washing / drying machine main body 44 and connected to the downward circulating air discharge port 36a. As described above, even if the air conditioner 39 is slightly larger in depth than the compressor 37 as described above, the upward circulation air inlet 39c located on the back side of the air conditioner 39 is used. The circulating air introduction pipe 16 can be raised and connected to a downward circulating air discharge port 36a at the back of the filter chamber 36. The filter chamber 36 is connected to the filter 3 from the top 44c of the washing / drying machine main body 44. Is a space S2 formed in a substantially triangular shape between the top 44c of the washing / drying machine main body 44 and the wall of the back 44b. The circulating air introduction port 39c is also positioned on the back portion 44b of the washing / drying machine main body 44, and the circulating air introduction pipe line 16 between the circulation air introduction port 39c of the air conditioner 39 and the washing / drying machine main body 44 is also provided. The pipe can be short and short on a plane along the back 44b.

  As a result, the circulating air introduction pipe line 16 from the water tank 3 to the filter chamber 36 can be piped using a dead space formed around the opening of the water tank 3 as shown in FIG. Space saving in 44 can be achieved, and downsizing of the drum type washing and drying machine 1 is achieved. Moreover, since the whole circulation ventilation path 5 becomes short, the thermal efficiency of laundry drying further increases.
