The operation and action of the washing / drying machine configured as described above will be described below. First, the procedure of the washing process is shown. First, the door 29 is opened, and laundry such as clothes is put into the drum 4 from the opening 7, and then the door 29 is closed and a desired operation program is selected by pressing an operation button (not shown). Let it begin.

  After confirming that the door 29 is closed, the control means 36 drives the motor 10 to determine the amount of clothes put in from load information such as the number of rotations. Thereafter, the water supply valve (not shown) is opened to start storing water in the water tank 2. When a predetermined amount of water is supplied in accordance with the amount of clothing, the water supply is stopped, and the drum 4 is rotated according to a predetermined program, for example, the motor 10 is rotated normally and reversely.

  The clothes in the drum 4 are lifted in the rotation direction by the baffle 13 and dropped from above in the drum 4 to remove dirt by the action of tapping, and when the predetermined time has passed, the washing process ends.

  Following the washing step, a rinsing step is then performed. In the rinsing process, rinsing operations such as drainage, water supply, and driving of the motor 10 are performed. The motor 10 is driven in a state where water is stored in the water tank 2, the detergent component and the dirt component adhering to the clothes are moved into the unclean water, and the rinse is performed to remove the dirt, and the predetermined time is reached. If it passes, one rinse operation will be complete | finished, and after repeating this twice, the water in the water tank 2 is discharged | emitted and a rinse process is complete | finished.

  Following the rinsing step, a dehydration step is then performed. In the dehydration step, the motor 10 is driven to rotate the drum 4 at a high speed (for example, 1400 rpm). At this time, as the rotational speed increases, the centrifugal force applied to the clothing increases, so that the clothing sticks to the inner peripheral surface of the drum 4. Moisture contained in the clothes moves from the through hole 12 of the drum 4 into the water tank 2 by centrifugal force, and the dehydrated water is discharged out of the machine through the drainage channel 27.

  Next, the drying process will be described. After the washing, rinsing and dehydration steps are performed, the clothes are dried. When the drying operation is started, the motor 10 rotates, the drum 4 and the blower 24 rotate, and a flow of drying air (arrow B) is generated. The drying air takes moisture from the clothes b inside the drum 4 and becomes humid, then passes through the drying filter 25 and is led to the evaporator 21 of the heat pump device 17 through the exhaust duct 16a. The drum 4 is rotationally driven by the motor 10 via the belt 11, and the clothes are stirred in the drum 4.

  When the compressor 18 of the heat pump device 17 is actuated, the refrigerant is compressed, and this pressure circulates through the condenser 19, the throttle means 20, and the evaporator 21. In the condenser 19, the heat of the refrigerant is released in a high pressure state, and in the evaporator 21, the pressure is reduced by the throttle means 20 to become a low pressure state, and the heat is absorbed into the refrigerant. At this time, the drying air flowing through the air passage 16 is heated by the heat of the condenser 19 by the blower 24.

  The warm air blown into the drum 4 from the air supply port 14 through the air supply duct 16c by the blower 24 is deprived of moisture when passing between the clothes and becomes dry, and then dried from the exhaust port 15. Foreign matters such as lint are removed through the filter 25 and led to the evaporator 21 of the heat pump device 17 through the exhaust duct 16a. When the humid drying air passes through the evaporator 21, sensible heat and latent heat are taken away and dehumidified, and the air is separated into dry air and dehumidified water.

  This dry air is heated again by the condenser 19, becomes warm air, and is blown again into the drum 4 by the blower 24. On the other hand, the dehumidified water condensed in the evaporator 21 is discharged from the drainage pipe 34 through the drainage channel 27 to the outside by the drainage pump 33.

Moist air that takes moisture from the clothes batter and is exhausted from the exhaust port 15 passes through an exhaust duct 16a that is located in front of the water tank 2 and extends downward from the upper part of the water tank 2 along the right wall 1c of the housing 1. As a result, the air flows into the case 23 from the inlet 23a located near the front surface 1b in the housing 1.

  The drying air that has flowed into the case 23 flows from the front surface 1 b side to the rear surface 1 a side in the housing 1 and passes through the evaporator 21 and the condenser 19. The drying air that has reached the blower 24 provided in the vicinity of the rear surface 1 a in the housing 1 passes through the air supply duct 16 c extending upward behind the water tank 2 and is introduced into the water tank 2 from the air supply port 14.

  That is, the drying air exhausted from the exhaust port 15 circulates in the drum 4 and the heat pump device 17 provided below the water tank 2 on the right wall 1 c side in the housing 1.

  On the other hand, the motor 10 that rotationally drives the drum 4 is located below the water tank 2 on the left wall 1 d side in the housing 1. Accordingly, the motor 10 is disposed on the left side of the vertical line A passing through the rotation axis RX of the drum 4 and the heat pump device 17 is disposed on the right side of the vertical line A, thereby positioning the water tank 2 in the housing 1. The center of gravity of the water tank 2 can be lowered. The motor 10 and the heat pump device 17 can obtain the same effect even if they are arranged with the left and right positions of the vertical line A turned over from the above.

  Therefore, in the washing / drying machine that performs the dehydration operation of rotating the drum 4 at a high speed, it is possible to reduce a large vibration that occurs when the laundry is biased in the drum 4 and to change the position of the water tank 2. By lowering down, the height of the housing 1 can be reduced, and downsizing is possible.

  In addition, since the heavy motor 10 and the compressor 18 of the heat pump device 17 are positioned diagonally in the lower part of the housing 1, the weight balance can be improved, and the stability during installation and operation can be improved. Can increase the sex.

  Further, the blower 24 is disposed behind the heat pump device 17, and the direction of the rotating shaft 24 b of the blower fan 24 a is set toward the heat pump device 17. Thereby, the upper part of the diameter direction of the ventilation fan 24a is located above the lowermost part 2a of the water tank 2 in the lower space formed between the rear part of the water tank 2 inclined upward and the rear surface 1a of the housing 1. By doing so, the large-diameter blower 24 can be compactly installed in a limited space in the housing 1, and the blowing ability can be enhanced.

  As shown in FIG. 6, the heat pump device 17 can be removed from the front side of the housing 1. When the screw 31 is removed from the state (a) in which the cover 30 is attached to the front surface 1b of the housing 1, the pressing of the case 23 of the heat pump device 17 by the pressing portion 32 is released as shown in (b). .

  Next, as shown in (c), when the case 23 installed on the frame 35 is lifted upward and pulled forward, the case 23 inserted into the duct 16b is detached, and the duct 16b The case 23 of the heat pump device 17 can be taken out while being held by the blower 24. Accordingly, the heat pump device 17 can be taken out without moving the housing 1 from the installation location, and maintenance work in a narrow place can be easily performed.

As described above, in the present embodiment, the water tank 2 elastically supported in the housing 1 and provided with the air supply port 14 and the exhaust port 15 for drying air, and the rotation axis RX extending in the front-rear direction in the water tank 2. A bottomed cylindrical drum 4 provided so as to be rotatable around the center of the water tank 2, a motor 10 which is fixed to the lower outer periphery of the water tank 2 and rotates the drum 4 via the belt 11, an air supply port 14 and an air exhaust port of the water tank 2. 15, a heat pump device 17 in which an evaporator 21 and a condenser 19 connected by a compressor 18 and a conduit 22 so that the refrigerant circulates are disposed in the air passage 16, and the air passage 16. The motor 10 and the heat pump device 17 are separated on the right side and the left side of the vertical line passing through the rotation axis RX of the drum 4, and the motor 10 is disposed in the housing 1. Arranged at the bottom of the rear side In addition, the heat pump device 17 is disposed in the lower part on the front side in the housing 1, and the housing 1 can be reduced in size by reducing the height, and the vibration of the drum 4 during high-speed rotation can be reduced.

Therefore, the motor 510 can appropriately rotate the drum 530 in the water tank 540. In the present embodiment, the left wall 750 is exemplified as the side wall and the first wall. The right wall 760 is exemplified as the second wall.

  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 exchanges heat with the exhaust air to produce dry air. The dry air is then fed into the washing tub 520 by the blower 620.

  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.

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
An air supply duct 640 disposed between the rear wall 740 and the outer bottom wall 542 is included. The air supply duct 640 is connected to the blower 620 and the outer bottom wall 542. The air supply duct 640 guides dry air from the blower 620 to the washing tub 520 along the rear wall 740. The air supply 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.

  The heat pump device 630 defines a compressor 635 that compresses the working medium flowing toward the condenser 634, a pressure reducing valve (not shown) that depressurizes the working medium flowing toward the evaporator 633, and a circulation path of the working medium. And a circulation tube 637. The compressor 635 is disposed at a corner corner defined by the left wall 750, the bottom wall 710 and the front wall 730. Circulation tube 637 forms a closed loop that passes through compressor 635, condenser 634, pressure reducing valve and evaporator 633.

  Since the compressor 635, the main heat exchanger 631, and the auxiliary heat exchanger 632 are closely arranged near the left wall 750, the circulation tube 637 is disposed between the left wall 750 and the main heat exchanger 631. It is mainly piped in the space.

  The compressor cover portion 657 includes a protruding portion 658 that protrudes between the left wall 750 and the auxiliary heat exchanger 632. As shown in FIG. 10, a part of the circulation tube 637 is disposed above the main heat exchanger 631 for connection with the compressor 635. The protrusion 658 appropriately covers the circulation tube 637 disposed above the main heat exchanger 631.

  As described above, the compressor 635 is disposed closer to the left wall 750 than the right wall 760 and closer to the front wall 730 than the rear wall 740. The blower 620 is disposed closer to the left wall 750 than the right wall 760 and closer to the rear wall 740 than the front wall 730. The motor 510 is disposed closer to the right wall 760 than the left wall 750 and closer to the rear wall 740 than the front wall 730. The drainage mechanism 400 is disposed closer to the right wall 760 than the left wall 750 and closer to the front wall 730 than the rear wall 740.

  When the drum 530 is a belt drive system, there is no open space especially below the water tank 540. Therefore, although the washing and drying machine tends to be large, the above-described configuration can effectively utilize the limited space below the water tank 540 and reduce the size of the main body. In particular, the installation position of the water tank 540 can be lowered by inclining the blower 620 having a height. Further, the compressor 635 having a height is disposed at a wall and a corner of the wall, and is disposed so as to avoid interference with the water tank 540. Therefore, the size of the main body in the height direction can be stored more compactly. Therefore, even when the size is standardized because the storage location of the washing / drying machine is determined, the degree of freedom in design can be increased. Furthermore, vibration during high-speed rotation of the drum 530 can be reduced.

  As described above, the washing and drying machine according to the present invention can be reduced in size by reducing the height of the casing, and can reduce vibration during high-speed rotation of the drum. Useful.
