JP 2006-230471 A

  Since the air deprived of moisture from the clothes is discharged from the water tank, the humidity of the air flowing through the plurality of flow paths is increased. Since the air layer surrounding the flow path prevents exhaust heat from the flow path, high-temperature air flows into the heat pump mechanism. The heat pump mechanism consumes a large amount of electric power to cool the high-temperature air. Accordingly, the heat exchange efficiency (heat exchange amount per power consumption) of the heat pump mechanism is lowered.

  An object of this invention is to provide the drying apparatus which dries clothing using the heat exchange technique which can achieve high heat exchange efficiency.

Since the second duct is fixed adjacent to the peripheral wall, the heat of the air flowing through the second duct is easily discharged through the peripheral wall. Therefore, the dehumidifying unit can cool and dehumidify the air easily and sufficiently. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: The said adjacent area may be prescribed | regulated between the said storage tank and the said heat exchange part.

  According to the said structure, since an adjacent area is prescribed | regulated between a storage tank and a heat exchange part, before the air reaches | attains a heat exchange part, the exhaust heat through a surrounding wall is promoted. Since the dehumidifying unit further lowers the temperature of the air that has cooled down while passing through the adjacent section, the air is sufficiently dehumidified. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  In the above configuration, the peripheral wall may be made of metal.

  According to the said structure, since a surrounding wall is metal, much heat is discharged | emitted through a surrounding wall. Therefore, the dehumidifying unit can cool and dehumidify the air easily and sufficiently. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: The said surrounding wall may also contain the side wall erected by the side of the said storage tank. The adjacent section may be adjacent to the side wall.

  According to the said structure, since an adjacent area adjoins the side wall standing by the side of the storage tank, the exhaust heat through a side wall is promoted. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: The said surrounding wall may also include the front wall in which the insertion port for throwing the said clothing into the said storage tank was formed. The adjacent section may be adjacent to the front wall.

  According to the said structure, the user can throw in clothing into a storage tank through the insertion port of a front wall. Since the adjacent section is adjacent to the front wall, exhaust heat through the front wall is promoted. The heat of the air flowing through the adjacent section is easily discharged through the peripheral wall. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: The said adjacent area may be formed in the corner | angular corner part between the said front wall and the said side wall.

  According to the said structure, since an adjacent area is formed in the corner | angular corner part between a front wall and a side wall, the exhaust heat through a front wall and a side wall is promoted. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: The said storage tank may also contain the rotating drum rotated so that the said clothing may be stirred. The second duct may include a tank fixing pipe attached to the storage tank, a wall fixing pipe including the adjacent section, and a connection pipe connecting the tank fixing pipe and the wall fixing pipe. The connecting pipe may reduce vibration transmitted from the rotating drum to the wall fixing pipe.

  According to the said structure, the air used for drying of clothing flows in into the tank fixing pipe attached to the storage tank, and goes to the wall fixing pipe containing an adjacent area through a connecting pipe after that. The heat of the air flowing through the adjacent section is easily discharged through the peripheral wall.

Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency. The rotating drum rotates to agitate the garment so that the garment is efficiently dried. Since the connecting pipe connecting the tank fixing pipe and the wall fixing pipe alleviates the vibration transmitted from the rotating drum to the wall fixing pipe, the vibration of the housing is reduced.

  In the above configuration, the housing may include a rear wall opposite to the front wall. The storage tank may include an outer tank that stores the rotating drum. The outer tub may include an outer front wall disposed between the rotating drum and the front wall, and an outer bottom wall opposite to the outer front wall.

Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  In the above configuration, the second duct may extend along the outer front wall and the front wall.

  According to the said structure, since a 2nd duct extends along an outer front wall and a front wall, the air layer which prevents the exhaust heat from a 2nd duct becomes thin enough. Therefore, the heat of the air flowing through the adjacent section is easily discharged through the front wall. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The said structure WHEREIN: In the said adjacent area, a said 2nd duct may contact the said surrounding wall.

  According to the above configuration, in the adjacent section, the second duct comes into contact with the peripheral wall, so that the heat of the air flowing through the adjacent section is easily discharged through the peripheral wall. Then, since the air heated by the heating part is sent into a storage tank by a fan, clothing is appropriately dried. Thus, dry air can dry clothing using heat exchange techniques that can achieve high heat exchange efficiency.

  The drying apparatus according to the present invention can dry clothes using a heat exchange technique capable of achieving high heat exchange efficiency.

However, an apparatus having only a drying function may be used as the drying apparatus.

(Washing and drying machine)
FIG. 1 is a schematic block diagram of a washing / drying machine 100 exemplified as a drying apparatus. The washing / drying machine 100 will be described with reference to FIG. A solid arrow in FIG. 1 represents a control signal path or a force transmission path. The dotted arrows in FIG. 1 indicate the flow of water. The arrow of the dashed-dotted line in FIG. 1 represents the flow of air.

  The washing / drying machine 100 includes a control unit 200, a water supply mechanism 300, a drainage mechanism 400, a clothing processing mechanism 500, a drying mechanism 600, and a housing 700. The laundry dryer 100 executes a washing process, a rinsing process, a dehydrating process, and a drying process. The control unit 200 controls the water supply mechanism 300, the drainage mechanism 400, the clothing processing mechanism 500, and the drying mechanism 600 according to these processes. The housing 700 houses the control unit 200, the water supply mechanism 300, the drainage mechanism 400, the clothing processing mechanism 500, and the drying mechanism 600.

  Clothing processing mechanism 500 includes a motor 510 and a washing tub 520. The user can store the clothes in the washing tub 520. The control unit 200 controls the motor 510 to rotate the washing tub 520 in the washing process, the rinsing process, the dehydrating process, and the drying process. As a result of the rotation of the washing tub 520, the clothes are agitated. In the present embodiment, the washing tub 520 is exemplified as a storage tub.

  The water supply mechanism 300 includes a water supply valve 310, a switching valve 320 and a detergent container 330. The water supply valve 310 and the switching valve 320 operate under the control of the control unit 200 in the washing process and the rinsing process. The user can store the detergent in the detergent container 330.

  The control unit 200 opens the water supply valve 310 in order to supply water to the washing tub 520 in the washing process and the rinsing process. The water that flows in through the water supply valve 310 reaches the switching valve 320. In the washing process, the control unit 200 controls the switching valve 320 to set a water supply path from the detergent container 330 to the washing tub 520. As a result, water containing a detergent is supplied to the washing tub 520 in the washing step. In the rinsing process, the control unit 200 controls the switching valve 320 to set a water supply path that directly goes from the switching valve 320 to the washing tub 520. As a result, tap water is supplied to the washing tub 520 in the rinsing step.

  The drainage mechanism 400 includes a circulation pump 410, a drainage valve 420, and a filter device 430. The control unit 200 appropriately controls the circulation pump 410 and the drain valve 420 in the washing process and the rinsing process. As a result, the washing step and the rinsing step are performed under a small amount of water.

  While the controller 200 operates the circulation pump 410, the drain valve 420 is closed. While the circulation pump 410 is operating, the water supplied to the washing tub 520 by the water supply mechanism 300 is circulated between the circulation pump 410 and the washing tub 520. The filter device 430 is disposed in the water path from the washing tub 520 to the circulation pump 410. The filter device 430 removes dust from the water discharged from the washing tub 520.

  In the washing process and the rinsing process, when the control unit 200 opens the drain valve 420, unnecessary water in the washing tub 520 is discharged out of the housing 700. The controller 200 may open the drain valve 420 also in the dehydration process. In the dehydration process, the water separated from the clothing is discharged out of the housing 700 through the drain valve 420.

  The drying mechanism 600 includes an air filter device 610, a blower 620, and a heat pump device 630. The controller 200 operates the blower 620 and the heat pump device 630 in the drying process. While the blower 620 operates, the air in the washing tub 520 is circulated between the washing tub 520 and the blower 620. The air filter device 610 and the heat pump device 630 are arranged in an air path from the washing tub 520 to the blower 620. The air filter device 610 is disposed between the washing tub 520 and the heat pump device 630. Therefore, the air filter device 610 can remove dust from the discharged air discharged from the washing tub 520. Thereafter, the heat pump device 630 cools and dehumidifies the discharged air. After the dehumidification process, the heat pump device 630 heats the exhaust air to produce dry air. The dry air is then fed into the washing tub 520 by the blower 620. In the present embodiment, the drying mechanism 600 is exemplified as a circulation mechanism.

  The clothes are agitated by the rotation of the washing tub 520. The dry air that has flowed into the washing tub 520 collides with clothes and takes away moisture. As a result, the clothes are dried. The humidity of the air that collides with clothing increases. The air that has collided with the clothing is then discharged from the washing tub 520 as discharged air.

  FIG. 2 is a schematic longitudinal sectional view of the washing / drying machine 100. With reference to FIG. 2, the washing and drying machine 100 will be further described.

  The casing 700 has a bottom wall 710 lying substantially horizontally below the washing tub 520, a top wall 720 lying substantially horizontally above the washing tub 520, and the washing tub 520 between the bottom wall 710 and the top wall 720. And a metal peripheral wall 790 erected so as to surround it. The peripheral wall 790 includes a front wall 730 erected between the bottom wall 710 and the top wall 720, and a rear wall 740 on the opposite side of the front wall 730. The washer / dryer 100 includes a rotatable door body 110 attached to the front wall 730. The front wall 730 is formed with an insertion port 731 that communicates with the washing tub 520. The door body 110 rotates between a closed position where the charging port 731 is closed and an open position where the charging port 731 is opened. Note that the door 110 shown in FIG. 2 is in the closed position.

  The washing tub 520 opens toward the front wall 730. The user can turn the door body 110 to the open position and put the clothes into the washing tub 520 through the insertion port 731. Thereafter, the user can close the door body 110 and confine the clothes in the washing tub 520.

  The washing tub 520 includes a rotating drum 530 that rotates about a rotation axis RX extending substantially horizontally between the front wall 730 and the rear wall 740 and stirs the clothes, and a water tank 540 that houses the rotating drum 530. The water tank 540 includes an annular outer front wall 543 disposed between the rotary drum 530 and the front wall 730, an annular protrusion 544 projecting from the inner edge of the outer front wall 543 toward the front wall 730, and an outer front An outer bottom wall 542 opposite to the wall 543 and a substantially cylindrical outer peripheral wall 541 surrounding the rotary drum 530 between the outer front wall 543 and the outer bottom wall 542 are included. In this embodiment, the water tank 540 is illustrated as an outer tank.

  FIG. 3 is a schematic rear view of the washing / drying machine 100. The washing / drying machine 100 will be further described with reference to FIGS. 2 and 3. In addition, the rear wall 740 is removed from the washing / drying machine 100 shown in FIG.

  The housing 700 further includes a left wall 750 erected adjacent to the front wall 730 and the rear wall 740, and a right wall 760 opposite to the left wall 750. The left wall 750 is erected on the left side of the washing tub 520. The right wall 760 is erected on the right side of the washing tub 520. The motor 510 described above is disposed at the corners defined by the right wall 760, the bottom wall 710 and the rear wall 740. The clothing processing mechanism 500 includes a rotating shaft 551 that passes through the outer bottom wall 542 and is connected to the rotating drum 530, a pulley 552 that is attached to the rotating shaft 551, and an endless belt 553 that transmits driving force from the motor 510 to the pulley 552. ,including. Therefore, the motor 510 can appropriately rotate the rotating drum 530 in the water tank 540. In the present embodiment, the left wall 750 is exemplified as a side wall.

  The above-described blower 620 is disposed at a corner portion defined by the left wall 750, the bottom wall 710, and the rear wall 740. The blower 620 is installed on the bottom wall 710. The drying mechanism 600 includes an inflow duct 640 disposed between the rear wall 740 and the outer bottom wall 542. Inflow duct 640 is connected to blower 620 and outer bottom wall 542. The inflow duct 640 guides dry air from the blower 620 to the washing tub 520 along the rear wall 740. The inflow duct 640 is curved so as to surround the pulley 552 that rotates between the outer bottom wall 542 and the rear wall 740. The outer bottom wall 542 is formed with an inlet (not shown) that allows air to flow into the washing tub 520. In addition, the technique of introducing dry air from the blower 620 to the washing tub 520 may be the same as the technique used for a known drying apparatus. In the present embodiment, the inflow duct 640 is exemplified as the first duct.

  As shown in FIG. 2, the drying mechanism 600 includes an exhaust duct 650 that guides exhaust air flowing from the washing tub 520 to the heat pump device 630 and the blower 620. The exhaust duct 650 is bent substantially perpendicularly from the vertical exhaust duct 651 between the front wall 730 and the outer front wall 543, and extends substantially horizontally from the vertical exhaust duct 651. Horizontal exhaust duct 652. In the present embodiment, the exhaust duct 650 is exemplified as the second duct.

  The vertical exhaust duct 651 defines a front side adjacent section adjacent to the front wall 730. Both the front wall 730 and the outer front wall 543 extend on a plane substantially perpendicular to the rotation axis RX. Accordingly, the vertical exhaust duct 651 can extend along the front wall 730 and the outer front wall 543. As a result, the vertical exhaust duct 651 is brought close to the front wall 730 in the front adjacent section. As described above, since the front wall 730 is made of metal, the heat of the discharged air is discharged out of the housing 700 through the front wall 730 while the discharged air from the washing tub 520 passes through the front adjacent section. It becomes easy. In the present embodiment, the front side adjacent section is exemplified as the adjacent section.

  FIG. 4 is a schematic perspective view of a horizontal exhaust duct 652 disposed in the housing 700. With reference to FIG.2 and FIG.4, the washing dryer 100 is further demonstrated. Note that the front wall 730 and the top wall 720 are removed from the housing 700 shown in FIG.

  The horizontal exhaust duct 652 extends along the left wall 750. The horizontal exhaust duct 652 includes a connection box 653 connected to the vertical exhaust duct 651, an accommodating portion 654 that accommodates part of the heat pump device 630, and a connecting duct 659 that guides dry air from the accommodating portion 654 toward the blower 620. ,including. An air filter device 610 is disposed in a junction box 653 disposed near the front wall 730. The air filter device 610 removes dust from the exhausted air immediately before the heat pump device 630. Within the housing portion 654, the heat pump device 630 exchanges heat with the exhaust air to produce dry air. The connection duct 659 is connected to a blower 620 disposed near the rear wall 740. The blower 620 sucks dry air in the connection duct 659. Thereafter, the blower 620 sends dry air to the washing tub 520 through the inflow duct 640.

  The front side adjacent section is defined between the washing tub 520 and the heat pump device 630. As described above, in the front side adjacent section, the temperature of the exhaust air from the washing tub 520 is greatly reduced. Therefore, the heat pump device 630 can easily reduce the temperature of the exhaust air to a level sufficient to dehumidify the exhaust air.

  FIG. 5 is a schematic diagram of the heat pump device 630. The heat pump device 630 will be described with reference to FIGS. 4 and 5.

  The heat pump device 630 includes a main heat exchanger 631 formed in the horizontal exhaust duct 652, a secondary heat exchanger 632 installed on the horizontal exhaust duct 652, a compressor 635, and a pressure reducing valve 636. The main heat exchanger 631 includes a dehumidifying unit 633 that cools and dehumidifies the exhaust air flowing in the horizontal exhaust duct 652, a heating unit 634 that heats the exhaust air after the dehumidification treatment by the dehumidifying unit 633, and generates dry air. including. In the present embodiment, the main heat exchanger 631 is exemplified as a heat exchange unit.

  The heat pump device 630 further includes a first circulation tube 681 that guides the working medium that flows from the compressor 635 to the pressure reducing valve 636, and a second circulation tube 682 that guides the working medium that flows from the pressure reducing valve 636 to the compressor 635. Since the compressor 635 compresses the working medium, the hot working medium flows along the first circulation tube 681. Since the pressure reducing valve 636 depressurizes the working medium, the low temperature working medium flows along the second circulation tube 682.

  The first circulation tube 681 is bent many times in the horizontal exhaust duct 652. The heating unit 634 includes a bent first circulation tube 681 and a plurality of heating fins 639 attached to the first circulation tube 681. Since the exhaust air flows along the heating fins 639, the heat of the heating fins 639 is smoothly transferred to the exhaust air. As a result, hot dry air is created.

  The second circulation tube 682 is bent many times in the horizontal exhaust duct 652. The dehumidifying part 633 includes a bent second circulation tube 682 and a plurality of cooling fins 638 attached to the second circulation tube 682. Since the exhaust air flows along the cooling fins 638, the heat of the exhaust air is smoothly transferred to the cooling fins 638. Since the amount of saturated water vapor in the exhaust air is reduced, moisture contained in the exhaust air is condensed on the cooling fins 638. As a result, the humidity of the exhaust air is reduced.

  As described above, before the exhaust air passes through the dehumidifying unit 633, the temperature of the exhaust air is reduced. Thereafter, the dehumidifying unit 633 further reduces the temperature of the discharged air, so that the discharged air is effectively dehumidified by the dehumidifying unit 633.

  The auxiliary heat exchanger 632 is formed between the heating unit 634 and the pressure reducing valve 636. The auxiliary heat exchanger 632 includes a heat exchanger 663 and a fan device 664. The first circulation tube 681 is bent a plurality of times outside the horizontal exhaust duct 652. The heat exhauster 663 includes a bent first circulation tube 681 and a number of exhaust heat fins 665 attached to the first circulation tube 681.

  As shown in FIG. 4, the heat exhauster 663 is disposed between the fan device 664 and the left wall 750. The fan device 664 sends out air (cooling air) toward the heat exhauster 663. The air sent out from the fan device 664 flows along the exhaust heat fins 665, and the exhaust heat from the exhaust heat fins 665 is promoted. The air sent out from the fan device 664 finally collides with the left wall 750. As described above, since the left wall 750 is made of metal, most of the heat from the exhaust heat fins 665 is released to the outside of the casing 700 through the left wall 750.

  As described above, the exhaust heat generator 663 promotes exhaust heat from the working medium that has passed through the heating unit 634, and reduces the temperature of the working medium that flows into the pressure reducing valve 636. Since the pressure reducing valve 636 subsequently reduces the pressure of the working medium, the cold working medium flows along the second circulation tube 682. As a result, the dehumidifying unit 633 can effectively dehumidify the discharged air.

(Vertical exhaust duct)
FIG. 6 is a schematic perspective view of the washing / drying machine 100. FIG. 7 is a schematic front view of the washing / drying machine 100. The vertical exhaust duct 651 will be described with reference to FIGS. 6 and 7. The top wall 720 and the front wall 730 are removed from the washing / drying machine 100 shown in FIG. The front wall 730 is removed from the washing / drying machine 100 shown in FIG.

  The vertical exhaust duct 651 extends while curving to the left from the upper part of the outer front wall 543 to the connection box 653. As a result, the vertical exhaust duct 651 defines a left adjacent section adjacent to the left wall 750. As described above, since the left wall 750 is made of metal, the heat of the discharged air is discharged out of the housing 700 through the left wall 750 while the discharged air from the washing tub 520 passes through the left adjacent section. It becomes easy. In the present embodiment, the left adjacent section is exemplified as the adjacent section. Note that the vertical exhaust duct 651 may be curved to the right. In this case, the vertical exhaust duct defines an adjacent section adjacent to the right wall 760.

  The vertical exhaust duct 651 includes an upper duct 691 attached to the outer front wall 543, a lower duct 692 defining a left adjacent section below the upper duct 691, and a bellows pipe connected to the upper duct 691 and the lower duct 692. 693. In the present embodiment, the upper duct 691 is exemplified as a tank fixing tube. The lower duct 692 is exemplified as a wall fixing tube. The bellows pipe 693 is exemplified as a connection pipe.

  The rotation of the rotating drum 530 causes the washing tub 520 to vibrate. As shown in FIG. 6, the washing / drying machine 100 includes a support spring 130 and a damper 140 that support the washing tub 520. The support spring 130 and the damper 140 absorb the vibration of the washing tub 520. Similar to the support spring 130 and the damper 140, the bellows tube 693 also reduces the vibration of the washing tub 520. Therefore, vibration transmitted to the lower duct 692 is reduced.

  FIG. 8A is a schematic cross-sectional view of the washer / dryer 100 across the front adjacent section and the left adjacent section. FIG. 8B is a schematic enlarged view of the structure in the rectangular frame shown in FIG. 8A. The lower duct 692 will be described with reference to FIGS. 2, 6, 8A and 8B.

  The lower duct 692 is disposed at a corner between the front wall 730 and the left wall 750. The lower duct 692 is fixed to the front wall 730 and / or the left wall 750. In the present embodiment, the lower duct 692 contacts the front wall 730 and the left wall 750. Accordingly, the heat of the exhaust air flowing in the lower duct 692 is discharged out of the casing 700 through the front wall 730 and the left wall 750. The lower duct may be slightly separated from the front wall 730 and / or the left wall 750.

  As shown in FIG. 6, the left wall 750 includes a main wall 751 erected from the left edge of the bottom wall 710, and a front flange that is bent from the front edge of the main wall 751 and used for connection to the front wall 730. 752 and an upper flange 753 bent from the upper edge of the main wall 751 and used for connection to the top wall 720.
