Description

  The present invention relates to a clothes dryer having a heat pump for drying clothes.

  2. Description of the Related Art Conventionally, clothes dryers that include a heat pump for drying clothes have been attracting attention as having good drying performance and being effective in saving energy. In a clothes dryer equipped with this heat pump, the air in the drying chamber containing the clothes is circulated through the ventilation path in which the evaporator and condenser of the heat pump are arranged, and the air is cooled and dehumidified with the evaporator. The garment is gradually dried by repeatedly heating the air with a condenser, sequentially feeding it into the drying chamber, and passing air deprived of moisture through the air passage.

  Therefore, moisture generated when the clothes are dried is collected by the evaporator, the latent heat absorbed in the folding is converted into a high-temperature refrigerant state by the compressor, and reused as energy for heating the air by the condenser. In this way, the energy can be reused without losing almost any energy except for a slight heat loss outside. Therefore, efficient drying can be realized.

In this case, the air path switching damper opens the air discharge path that communicates from the ventilation path to the outside of the machine, and the evaporator is connected to the outside of the ventilation path from the intake port provided in the ventilation path. It is possible to cool a space such as a washroom in which a clothes dryer is installed by switching so that the air discharge passage and the opening and closing member provided in the air discharge passage are discharged to the outside through the outlet portion opened. It is considered (for example, refer to Patent Document 1).

Water is injected into the water sprinkler 43 via 44.
In addition, a control device 48 is provided on the back side of the upper portion of the front portion of the outer box 1. The control device 48 is mainly composed of a microcomputer, for example, and functions as a control means for controlling the overall operation of the washing / drying machine.

On the other hand, from the lower part of the front end portion of the ventilation case 23 where the air suction port 24, which is the portion between the rotary tank 3 and the evaporator 35, in the ventilation path 32, forward and upward outside the machine An air discharge path 49 is provided. The air discharge path 49 communicates with the air inlet 24, and an air path switching damper 50 is provided at the communicating portion.
More specifically, the air path switching damper 50 is positioned on the air discharge path 49 side, and is supported by the shaft 51 so as to be pivotable up and down. (Part between the rotary tank 3 and the evaporator 35 in the ventilation path 32) is made of a plate-like one that switches between closing and opening and simultaneously switching between opening and closing the air discharge path 49. .

  The air discharge passage 49 is provided with a blower for air discharge 52. In this case, the air blower for air discharge 52 is a cross-flow fan, and is a horizontally long impeller inside the air discharge passage 49 that also serves as a casing. 53, and the cross-flow impeller 53 is rotated by a motor (not shown) arranged in parallel outside the air discharge path 49.

  Further, an opening / closing member 55 is provided at the outlet 54 of the air discharge path 49. As shown in FIG. 5, the opening / closing member 55 has a horizontal semi-cylindrical shape in the horizontal direction, and has a horizontally long ventilation port 56 in the shape of a grill on the curved peripheral side portion. A shaft 57 is provided at one end of the shaft, a shaft (not shown) is provided at the other end, and these shafts are rotatably supported on both sides of the air discharge passage 49.

  Here, FIG. 5 also shows a common driving device 58 for switching and driving the air path switching damper 50 and the opening / closing member 55. As shown in FIGS. 1, 2, 6, and 7, the drive device 58 has a motor (particularly a stepping motor) 59 as a drive source, and is attached to the rotation shaft of the motor 59. A drive-side gear 60, a disc-shaped first drive-side crank 61, a first link 62 having one end rotatably connected to an eccentric portion of the first drive-side crank 61, and the other end of the first link 62 A lever-shaped first driven crank 63 having a portion rotatably connected to one end, a driven gear 64 meshed with the drive gear 60, and a disk coaxially mounted on the driven gear 64 with a shaft 65 The second drive side crank 66, the second link 67 having one end rotatably connected to the eccentric part of the second drive side crank 66, and the other end of the second link 67 are rotated to the eccentric part. A disk-like second driven crank 6 connected in a movable manner The has.

  Accordingly, the other end of the first driven crank 63 is attached to the shaft 51 of the air path switching damper 50, and the shaft 57 of the opening / closing member 55 is attached to the center of the second driven crank 68. Yes.

  As a result, when the motor 59 is rotated, the first drive side crank 61 is rotated and the drive side gear 60 is driven to the driven side gear as indicated by arrows in FIGS. 1, 2, 6, and 7. Rotational power is transmitted to 64 and the second drive side crank 66 rotates. The rotation directions of the first drive side crank 61 and the second drive side crank 66 are opposite to each other, but the rotation of the first drive side crank 61 is performed via the first link 62 to the first driven crank 63. The first driven crank 63 rotates the shaft 51 of the air path switching damper 50 to rotate the air path switching damper 50. The rotation of the second drive side crank 66 is transmitted to the second driven crank 68 via the second link 67, and the second driven crank 68 opens and closes by rotating the shaft 57 of the opening / closing member 55. The member 55 is rotated.

  Accordingly, the first drive-side crank 61, the first link 62, and the first driven-side crank 63 constitute a transmission mechanism 69 that transmits the rotational power of the motor 59 to the air path switching damper 50. The gear 60, the driven side gear 64, the shaft 65, the second drive side crank 66, the second link 67, and the second driven side crank 68 have a transmission mechanism 70 that transmits the rotational power of the motor 59 to the opening / closing member 55. It constitutes.

  In addition, FIGS. 1, 2, 6, and 7 show a microswitch 71 arranged in parallel with the first drive-side crank 61. This microswitch 71 is clearly shown in FIG. 8. As described above, the operation button 71 a corresponds to the outer peripheral cam portion 61 a of the first drive side crank 61, and the operation button 71 a is projected and retracted by the outer peripheral cam portion 61 a as the first drive side crank 61 rotates. Thus, an opening / closing operation is performed, thereby functioning as a detecting means for detecting the driving state of the driving device 58.

  Here, as described above, the rotation of the air path switching damper 50 by the drive device 58 switches between the opening and closing of the air intake port 24 of the ventilation case 23 and simultaneously switching between opening and closing the air discharge path 49. It is something to do. On the other hand, the rotation of the opening / closing member 55 opens the outlet portion 54 of the air discharge passage 49 when the air outlet 56 of the opening / closing member 55 is aligned with the outlet portion 54 of the air discharge passage 49. When a portion other than the ventilation port 56 of the opening / closing member 55 is fitted to the outlet portion 54 of 49, the outlet portion 54 of the air discharge path 49 is closed.

  Therefore, the detection of the driving state of the driving device 58 by the micro switch 71 detects the opening / closing of the air discharge path 49 by the air path switching damper 50 and the opening / closing of the outlet portion 54 of the air discharge path 49 by the opening / closing member 55. Also, based on the detection, when the air path switching damper 50 and the opening / closing member 55 reach the correct open position (see FIGS. 2 and 7) and when they reach the correct close position (FIGS. 1 and 6). The pulse signal applied to the motor 59 is stopped, the rotation of the air path switching damper 50 and the opening / closing member 55 by the motor 59 are stopped, and the air path switching damper 50 and the opening / closing member are stopped. 55 is stopped in the correct open position and the correct closed position.

  In addition, FIG. 5 shows a case 72 of the driving device 58, in which the motor 59 and the microswitch 71 are housed, and in addition, a first part which is a part of the transmission mechanisms 69 and 70 is shown. The drive side crank 61 and one end side of the first link 62, the drive side gear 60, the driven side gear 64, and the shaft 65 are accommodated, and the remaining side of the shaft 65 on the second drive side crank 66 side is accommodated. The end, the second drive-side crank 66, the second link 67, and the second driven-side crank 68 are exposed.

  The drive device 58 has the motor 59, the transmission mechanisms 69 and 70, the micro switch 71, and the case 72 as a unit, and is attached to the ventilation case 23 in the united state. The road switching damper 50 and the opening / closing member 55 are connected.

  Further, FIGS. 9 and 10 are enlarged views of a portion of the driving device 58 that is connected to the transmission member 55 from the second driven crank 68 to the opening / closing member 55, and the central portion of the second driven crank 68 is shown. In addition, a connecting hole 73 is formed, and through holes 74 and 75 and a through groove 76 are formed on both sides thereof to form a flexible portion 77. In this case, in detail, the through grooves 74 and 75 communicate with the connecting hole 73 and extend in an L shape from one diametrical direction to a direction perpendicular thereto, whereas the through grooves 76 The connecting holes 73 are formed so as to extend along the outer sides of the through grooves 74 and 75, and as a result, both sides of the connecting hole 73 are flat by linear flexible portions 77. Further, both side portions of the connecting hole 73 in the direction orthogonal to the direction in which the flexible portion 77 faces are arcuate.

  On the other hand, the shaft 57 of the opening / closing member 55 has flat portions 78 and 79 formed symmetrically on both sides, respectively, and this shaft 57 is inserted into the connecting hole 73 of the second driven crank 68. Thus, the pair of flat portions 78 are brought into contact with the flexible portion 77, and thus the transmission of the rotational force from the second driven crank 68 to the shaft 57 of the opening / closing member 55 is transmitted from the flexible portion 77. The rotation force is transmitted to the flat portion 78.

Next, the operation and effect of the washing / drying machine having the above-described configuration will be described.
In the washing and drying machine having the above configuration, when a standard operation course is started, a washing (washing and rinsing) operation is started first. In this washing operation, an operation of supplying water into the water tub 2 is performed by the water supply valve 45, and then the motor 16 is operated to rotate the rotating tub 3 alternately in both forward and reverse directions at a low speed. Thereby, the laundry is stirred and washed with the washing water.
When the washing operation is completed, the dehydration operation is then started. In this dehydration operation, after the water in the water tank 2 is discharged, an operation of rotating the rotating tank 3 in one direction at a high speed is performed. Thereby, the laundry in the rotating tub 3 is centrifugally dehydrated.

  When the dehydration operation is completed, a drying operation is next performed. In this drying operation, as shown in FIGS. 1, 3, and 6, the air path switching damper 50 is set in a state in which the air inlet 24 of the ventilation case 23 is opened and the air outlet path 49 is closed. (The opening / closing member 55 is also set to close the outlet 54 of the air discharge passage 49). In this state, the circulation fan 27 is operated while rotating the rotating tub 3 in both forward and reverse directions at a low speed. Then, due to the air blowing action of the centrifugal impeller 33, the air in the rotating tub 3 flows from the water tank 2 into the hot air outlet 11, the return air duct 25, the flexible hose 26, and the ventilation case 23 as indicated by arrows in FIG. 3. It flows into the ventilation case 23 through the air inlet 24.

  At this time, the operation of the compressor 37 of the heat pump 39 is started. As a result, the refrigerant sealed in the heat pump 39 is compressed to become a high-temperature and high-pressure refrigerant, and the high-temperature and high-pressure refrigerant flows into the condenser 36 and exchanges heat with the air in the ventilation case 23. As a result, the air in the ventilation case 23 is heated, and conversely, the temperature of the refrigerant is lowered and liquefied. The liquefied refrigerant then passes through the throttle valve 38 and is decompressed, and then flows into the evaporator 35 and vaporizes. Thereby, the evaporator 35 cools the air in the ventilation case 23. The refrigerant that has passed through the evaporator 35 returns to the compressor 37.

  As a result, the air that has flowed into the ventilation case 23 from the inside of the rotating tub 3 is cooled by the evaporator 35 and dehumidified, and then heated by the condenser 36 to be warmed. Then, the hot air is supplied into the rotary tank 3 through the flexible hose 30, the air supply duct 31, the hot air inlet 12, the hot air passage 19, the hot air introduction port 17, and the hot air introduction hole 18.

The hot air supplied into the rotary tub 3 takes away moisture from the laundry, and then passes through the water tub 2 through the hot air outlet 11, the return air duct 25, the flexible hose 26, and the air intake port 24 of the ventilation case 23. It flows into the case 23.
Thus, air circulates between the ventilation case 23 having the evaporator 35 and the condenser 36 and the rotating tub 3, thereby drying the laundry in the rotating tub 3. Therefore, in this case, the inside of the rotary tank 3 functions as a drying chamber.

  On the other hand, when the space where the washing / drying machine is installed is cooled, as shown in FIGS. 2, 7, and 11, the air path switching damper 50 opens the air discharge path 49 to ventilate the air. The air intake port 24 of the case 23 is switched to the closed state, and the opening / closing member 55 is switched to the state in which the outlet 54 of the air discharge path 49 is opened. In this state, the operation of the compressor 37 of the heat pump 39 is started and the blower fan 52 is operated.

  As a result, as indicated by solid arrows in FIG. 11, the air outside the ventilation case 23 is sucked into the ventilation case 23 from the intake port 41 and is cooled through the evaporator 35. Then, the cooled air passes from the air outlet passage 49 through the air outlet blower 52 through the air outlet fan 52 to the front side outside the machine from the outlet portion 54 of the air outlet passage 49 (the air outlet 56 of the opening and closing member 55). The space where the washing and drying machine is installed is cooled.

Further, at this time, as shown by a broken line arrow in FIG. 11, water is supplied from the water supply valve 45 to the water sprayer 43 through the water injection tube 44, and the water supplied to the water sprayer 43 is supplied to the condenser 36. The condenser 36 is cooled down. Thus, the heat energy absorbed when the air is cooled by the evaporator 35 and the heat energy added by the work of the compressor 37 are released from the condenser 36 to water as a cooling medium. Then, the water is discharged from the condenser 36 together with the absorbed thermal energy, so that the condenser 36 does not become abnormally high, and the evaporator 35 becomes low temperature correspondingly, and operates effectively as a cooling system. The cooling of the space where the washing / drying machine is installed can be made desirable.
The water that has fallen on the condenser 36 is received by a drain pan (not shown) and discharged outside the apparatus by a drain pump (not shown).

  In addition, when the space where the above-described washing / drying machine is installed is cooled, if the heat pump 39 is not operated and the electric heater 42 is operated instead, and the air blower 52 is operated, the air intake 41 The air outside the ventilation case 23 sucked in from the air is heated by the electric heater 42 to be warmed, and the warm air passes through the air blowing fan 52 through the air blowing fan 52 and the air discharge path 49 where the opening / closing member 55 is opened. The outlet part 54 (the vent 56 of the opening / closing member 55) is discharged forward from the outside of the machine, thereby heating the space where the washing / drying machine is installed.

  Thus, in this configuration, the clothes are dried by circulating the air in the rotary tub 3 (drying chamber) through the ventilation path 32 in which the evaporator 35 and the condenser 36 of the heat pump 39 are arranged, and the air path is switched. The damper 50 opens the air discharge path 49 that communicates from the ventilation path 32 to the outside of the machine, and the evaporator 35, the air discharge path 49, In addition, the air path switching damper 50 and the opening / closing member 55 are switched and driven by a common drive device 58 in order to switch the air opening / closing member 55 provided in the air discharge path 49 to be discharged to the outside through the open outlet 54. Like to do.

  Thereby, the switching drive of the air path switching damper 50 and the opening / closing member 55 can be performed without requiring separate driving devices, and thus a product can be provided at low cost. Further, the assembly of the product and the like can be prevented from being complicated.

  In addition, in the case of this configuration, a micro switch 71 is provided as a detecting means for detecting the driving state of the driving device 58. Accordingly, the detection of opening / closing of the air path switching damper 50 and the opening / closing member 55 can be performed by the common detection means, and the opening / closing control of the air path switching damper 50 and the opening / closing member 55 by detecting them can be further reduced. Can be offered cheaply.

  The driving device 58 includes the motor 34 as a driving source, transmission mechanisms 69 and 70 for transmitting the rotational power of the motor 34 to the air path switching damper 50 and the opening / closing member 55, the micro switch 71, and the motor 34 and the micro switch. A case 72 that houses 71 (detection means) is unitized. Thereby, the attachment and connection of the drive device 58 can be performed in a united state, and the assemblability can be further improved.

Further, the transmission connection of the opening / closing member 55 is made by the flexible portion 77. As a result, when the opening / closing member 55 is difficult to rotate due to clogging of foreign matter or the like, and when the driving device 58 is overloaded, the flexible portion 77 is bent and detached from the abutting flat portion 78, Since transmission to the opening / closing member 55 is avoided, the opening / closing member 55 is forcibly opened / closed so as not to be damaged.
In addition to the flat portion 78, the shaft 57 of the opening / closing member 55 has a flat portion 79. In order to avoid the occurrence of an overload by changing the flat portion 79 so as to contact the flexible portion 77 when the flat portion 78 easily causes an overload of the driving device 58. That is, the transmission adjustment of the opening / closing member 55 can be performed.

  The present invention is not limited only to the embodiment described above and shown in the drawings. In particular, the washing and drying machine as a whole is not limited to the above-described horizontal axis shape, and a vertical axis having a water tank and a rotating tank in a vertical axis shape. It may be in the form, and is not limited to a washing and drying machine having both a washing function and a drying function, and can be applied to a clothes drying machine having only a drying function.
