BACKGROUND OF THE INVENTION
  The present invention relates to a clothes dryer used in general households.
[0002]
[Prior art]
  A conventional clothes dryer has a structure as shown in FIG. That is, the apparatus includes a drying cabinet 1 for storing clothes, a blowing unit 2 for sending air into the drying cabinet 1, a heating unit 3 for heating the blowing air, and a control unit 4. At this time, the supply of air into the drying chamber 1 is performed by the air outside the chamber which the air blowing means 2 sucks from the intake port 5, and the exhaust of the air from the drying chamber 1 is opened at the upper part of the drying chamber 1. The exhaust port 6 is connected. In the drying cabinet 1, clothes such as laundry are accommodated as shown in the figure.
[0003]
  With the above configuration, when the user operates an operation unit (not shown) and starts operation, the blowing unit 2 and the heating unit 3 start to operate, and warm air is sent into the drying chamber 1. Drying of clothing proceeds by this warm air. At this time, the air that has become highly humid due to drying is exhausted from the exhaust port 6 to the outside of the cabinet.
[0004]
[Problems to be solved by the invention]
  The conventional clothes dryer has a problem that the heating condition of the heating means is constant and the energy efficiency is poor.
[0005]
  In other words, the conventional clothes dryer always heats the outside air and applies it to the clothes, and consumes a lot of energy. In addition, at the end of clothing drying, the amount of moisture contained in the clothing is low and the amount of moisture contained in the clothing cannot move to the surface of the clothing. Only the surface is in a dry state. That is, at the end of clothing drying, the factor that determines the drying time is the same as in the early stages of drying, although the air velocity and temperature / humidity conditions of the dry air that hits the clothing have changed to the internal factor of moisture movement of the clothing itself. It is dried under the drying conditions of

Reference numeral 8 denotes dehumidifying means for sucking air in the drying chamber 7 and dehumidifying it, and then discharging it into the drying chamber 7 again. An intake pipe 12 connected to the exhaust hole 7 a of the drying chamber 7 is provided at the lower part of the dehumidifying means 8 at the intake port 10 provided at the upper part of the dehumidifying means 8.Discharge port9 is connected to a blower pipe 13 inserted into the lower part of the drying chamber 7 from the air inlet 7b of the drying chamber 7. The air duct 13 has a large number of air outlets 13a.
[0009]
  That is, the air in the drying chamber 7 is sucked from the intake pipe 12 by the blowing function of the dehumidifying means 8, is dehumidified and dried by the dehumidifying function of the dehumidifying means 8, and is dried from the blowing pipe 13 to the drying box 7. It repeats the circulation returning to the inside. Moreover, the dehumidifying means 8 has a control means 11 inside, and controls the air blowing function and the dehumidifying function.
[0010]
  The operation of this embodiment will be described below. FIG. 2 is a flowchart showing a control program that the control means 11 of this embodiment has. When the user operates an operation unit not shown in the figure, the control means 11 confirms the start of operation in step 1. Next, in step 2, timing of the operation time of the drying operation is started. At the same time, in step 3, the dehumidifying means 8 is turned on to start the circulation of air in the drying chamber 7. That is, the air in the drying chamber 7 is sucked from the intake pipe 12 by the blowing function of the dehumidifying means 8, is dehumidified and dried by the dehumidifying function of the dehumidifying means 8, and is dried from the blowing pipe 13 to the drying box 7. Repeat the circulation back inside. In step 4, it is confirmed whether the circulation time is performed for a predetermined time. If the result of the check in step 4 is NO, the operation of the dehumidifying means 8 in step 3 is continued. If the result of the check in step 4 is YES, that is, if a predetermined time has elapsed, the routine proceeds to step 5 where the power consumption of the dehumidifying means 8 is reduced to a predetermined value.
[0011]
  That is, when the air in the drying cabinet 7 circulates between the dehumidifying means 8 for a predetermined time, the clothing in the drying cabinet 7 is drying, and the amount of moisture released from the clothing is reduced. Is. Therefore, in this embodiment, the power consumption of the dehumidifying means 8 is reduced to a predetermined value at this stage. In addition, although the said electric power is what the motor and heater which the dehumidification means 8 have are controlled by phase control etc., in this Example, it is not necessary to specifically limit this electric power control means.
[0012]
  Subsequently, in step 6, it is further confirmed whether or not the drying operation has passed for the next predetermined time (hereinafter referred to as a second predetermined time). If the second predetermined time has elapsed, the process proceeds to step 7. In step 7, the dehumidifying means 8 is further controlled to further reduce the power consumption of the dehumidifying means 8 to the next predetermined value. That is, since the clothes in the drying cabinet 7 are further dried, the power consumption of the dehumidifying means 8 is further reduced at this stage. If the result of the check at step 6 is NO, the operation of the dehumidifying means 8 at step 5 is continued.
[0013]
  In the present embodiment, next, in step 8, it is confirmed whether or not a third predetermined time has passed, and in step 9, the power consumption of the dehumidifying means 8 is further reduced. If the result of the check at step 8 is NO, the operation of the dehumidifying means 8 at step 7 is continued.
[0014]
  Next, the process proceeds to step 10 to check whether or not the total operation time has reached a predetermined value. If YES, the process proceeds to step 11 to turn off the dehumidifying means 8 and finish drying. Wait until operation starts.
[0015]
  As described above, in this embodiment, the drying chamber 7 for storing clothes, the dehumidifying means 8 for sucking the air in the drying chamber 7 and dehumidifying it, and discharging it again into the drying chamber, the drying chamber 7 and the dehumidifying means 8. And a control means 11 for controlling the dehumidifying means 8, and the control means 11 gradually reduces the dehumidifying power of the dehumidifying means 8 as the drying time elapses. As a configuration that reduces the number of clothes, an energy efficient clothes dryer is realized.
[0016]
  In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three stages, but there is no problem even if the control is performed in two stages or more than four stages.
[0017]
  (Example 2)
  Next, a second embodiment of the present invention will be described. FIG. 3 is a cross-sectional view showing the configuration of this embodiment. In this embodiment, the dehumidifying means 8 uses an adsorbing portion 18, a first air blowing means 19, a second air blowing means 20 and a heating means 21.
[0018]
  FIG. 4 is a perspective view showing the configuration of the dehumidifying means 8 used in this embodiment. The adsorbing unit 18 adsorbs moisture from the air in the drying chamber 7 sucked from the intake pipe 12, and has a configuration shown in FIG. That is, the adsorbing part 18 is constituted by an adsorbent 18a having a honeycomb structure in which silica gel, zeolite, or calcium chloride is molded into a disk shape or a cylindrical shape and a large number of through holes are opened so that air flows in the axial direction. . Further, the adsorbent 18 a is rotated by the rotor motor 22 and the belt 23. A partition plate 24 and a partition plate 25 are arranged on the surface of the adsorbent 18a, and the partition plate 24 and the partition plate 25 slide on both surfaces of the adsorbent 18a. The adsorbent 18 a is separated into an adsorption zone 26 and a regeneration zone 27 by the partition plate 24 and the partition plate 25.
[0019]
  That is, the adsorbing unit 18 rotates the adsorbent 18a by the rotor motor 22 and the belt 23, and the intake air sucked from the intake pipe 12 connected to the exhaust hole 7a of the drying chamber 7 by the first blower 19. The air is circulated from the blower pipe 13 into the drying chamber 7 through the adsorbent 18a. At this time, the intake air sucked from the intake pipe 12 comes into contact with the adsorption zone 26 of the adsorbent 18a, so that moisture is adsorbed by the adsorbent 18a and is dried. In addition, the outside air blown by the second blowing means 20 is heated and brought into contact with the regeneration zone 27 of the adsorbent 18a by the heating means 21, and the contacted outside air is exhausted out of the apparatus by the second blowing means 20 again. Yes. That is, in the regeneration zone 27, the hot air heated by the heating means 21 separates the moisture adsorbed by the adsorbent 18a, thereby regenerating the adsorbent 18a and recovering the adsorption capacity of the adsorbent 18a. It is. The water adsorbed in the adsorption zone 26 is separated by passing through the regeneration zone 27, and the adsorbent 18a is automatically regenerated. The partition plate 24 and the partition plate 25 slide on the surface of the adsorbent 18a as the adsorbent 18a rotates, and partition the adsorbing zone 26 and the regeneration zone 27 so that there is no gap between the surfaces. There are no air leaks between the zones.
[0020]
  The operation of this embodiment will be described below. FIG. 5 is a flowchart showing a control program that the control means 11 of this embodiment has. In step 101, the start of the operation is confirmed, and in the subsequent step 102, the operation time of the drying operation is started. At the same time, in step 103, the first blowing means 19, the second blowing means 20, the heating means 21, and the rotor motor 22 constituting the dehumidifying means 8 are turned on. That is, the air in the drying chamber 7 is sucked and dehumidified by the adsorption unit 18. At this time, since the adsorbent 18a adsorbs moisture contained in the humid air in the drying chamber 7, heat of adsorption is generated by the condensation of water during the adsorption of the moisture. Therefore, the air that has passed through the adsorption unit 18 is heated by the adsorption heat and becomes high-temperature, low-humidity dry air. The dry air is blown into the drying chamber 7 from the blower pipe 13 by the blow of the first blower 19. The air blown into the drying chamber 7 comes into contact with the clothing in the drying chamber 7 to dry the clothing. The air that has become low-temperature and high-humidity including moisture released from the clothing is sent again to the dehumidifying means 8 from the intake pipe 12 connected to the exhaust hole 7a.
[0021]
  In subsequent step 104, it is confirmed whether or not the duration of the drying operation has reached a predetermined time. If the result of this check is YES and a predetermined time has elapsed, the process proceeds to step 105. In step 105, the heating means 21 constituting the dehumidifying means 8 is controlled to reduce the power consumption to a predetermined value. The electric power control for the heating means 21 includes, for example, a method of performing phase control on a supply voltage from a commercial power source, and this energization method is not particularly limited in this embodiment.
[0022]
  The reason why the energization power to the heating means 21 is reduced to a predetermined value as the predetermined time elapses is the same as described in the first embodiment. That is, the moisture contained in the clothes housed in the drying chamber 7 is reduced as a predetermined time passes, and the amount of moisture released from the clothes from this stage is less than that in the initial stage of drying. Therefore, the amount of moisture that the adsorption unit 18 performs the adsorption treatment is also reduced, and the adsorbent 18a.TheThis is because less power is required for reproduction. If the result of the check at step 104 is NO, the operation of each part at step 103 is continued.
[0023]
  Subsequently, in step 106, it is confirmed whether or not the second predetermined time described in the first embodiment has elapsed. When the result of the check is YES, the routine proceeds to step 107, where the energization power of the heating means 21 constituting the dehumidifying means 8 is reduced to the next predetermined value. Further, in step 108, it is checked whether or not the third predetermined time has passed in the drying operation. If the result of the check is YES, the process proceeds to step 109 and the heating means 21 constituting the dehumidifying means 8 is checked. The energization power is reduced to the next predetermined value. As a result of the check in the next step 110, when the total operation time reaches a predetermined value, the process proceeds to step 111, where the first blowing means 19, the second blowing means 20, the heating means 21 and the rotor motor 22 are turned off. Finish drying and wait until the next operation starts. In addition, while the result of the check in step 106, step 108, and step 110 is NO, the energized state in each step is maintained.
[0024]
  As described above, according to the present embodiment, the drying chamber 7 for storing clothes, the adsorbent 18a for adsorbing moisture from the air in the drying chamber 7, and the air in the drying chamber 7 are sucked into the adsorbent 18a. First air blowing means 19 for discharging again into the drying chamber 7 via the second air blowing means 20, second air blowing means 20 for sucking air outside the drying chamber 7 and exhausting it again outside the drying chamber 7 via the adsorbent 18a, 2 Dehumidifying means 8 comprising heating means 21 for heating the adsorbent 18a by raising the temperature of the air outside the drying chamber 7 sucked by the blower means 20, and the drying chamber 7 and the dehumidifying means 8 are connected. As a configuration comprising an intake pipe 12 and a blower pipe 13 and a control means 11 for controlling the dehumidifying means 8, the control means 11 gradually reduces the heating power of the heating means 21 as the drying time elapses. Realizing an energy efficient clothes dryer It is intended.
[0025]
  In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three stages, but there is no problem even if the control is performed in two stages or more than four stages.
[0026]
  (Example 3)
  Next, a third embodiment of the present invention will be described. The configuration of this embodiment is the same as that of the second embodiment, and only the configuration of the control program that the control means 11 has is different. FIG. 6 is a flowchart showing a control program that the control means 11 of this embodiment has.
[0027]
  The operation of this embodiment will be described below. In step 201, the start of the operation is confirmed, and in step 202, the operation time of the drying operation is started. At the same time, in step 203, the first air blowing means 19, the second air blowing means 20, the heating means 21, and the rotor motor 22 constituting the dehumidifying means 8 are turned on, the air in the drying chamber 7 is sucked, and the adsorption unit 18 dehumidifies. . At this time, as described in the second embodiment, the adsorbent 18a generates heat of adsorption due to condensation of the adsorbed moisture, and the blown air blown into the drying chamber 7 by the first blowing means 19 is high temperature and low humidity. It is dry air. The dry air comes into contact with the clothes in the drying cabinet 7 to dry the clothes. The air that has become low-temperature and high-humidity including moisture released from the clothing is sent again to the dehumidifying means 8 by the first blowing means 19.
[0028]
  Subsequently, in step 204, it is confirmed whether or not the drying operation has continued for a predetermined time. If the result of this check is YES, the routine proceeds to step 205, where the power consumption of the second blower means 20 and the heating means 21 is reduced by a predetermined amount. The operation is continued in this state, and when it is confirmed in step 206 that the operation time has reached the second predetermined time, in step 207, the power consumption of the second blower means 20 and the heating means 21 is further reduced by a predetermined amount. . The reason for this is that, as described in the first embodiment or the second embodiment, when the drying progresses after a predetermined time has elapsed, the amount of moisture released from the garment decreases. This is because the amount of dehumidification to be dehumidified is small. In this embodiment, the power consumption for the regeneration of the adsorbent 18a is reduced by reducing the power consumption of the second blowing means 20 and the heating means 21 by a predetermined amount.
[0029]
  Further, in step 208 and step 209, this reduction in power consumption is repeated once more. Subsequently, in step 210, when it is confirmed that the total operation time has reached a predetermined value, the process proceeds to step 211, where the first air blowing means 19, the second air blowing means 20, the heating means 21 and the rotor motor 22 are turned off and drying is performed. End and wait until the next operation starts. In addition, while the result of the check in step 106, step 108, and step 110 is NO, the energized state in each step is maintained.
[0030]
  As described above, according to the present embodiment, the drying chamber 7 for storing clothes, the adsorbent 18a that adsorbs moisture from the air in the drying chamber 7, and the air in the drying chamber 7 is sucked to remove the adsorbent 18a. First air blowing means 19 that discharges again into the drying chamber 7 through the air, second air blowing means 20 that sucks air outside the drying chamber 7 and exhausts the air outside the drying chamber 7 again through the adsorbent 18a, Dehumidifying means 8 comprising heating means 21 for heating the adsorbent 18a by raising the temperature outside the drying chamber 7 sucked by the blowing means 20, and an intake pipe connecting between the drying chamber 7 and the dehumidifying means 8 12 and a blower pipe 13 and a control means 11 for controlling the dehumidifying means 8, and the control means 11 supplies the amount of air blown from the second blower means 20 and the energizing power to the heating means 21 as the drying time elapses. As a configuration to gradually reduce the energy, Those that achieve the rate of good clothes dryer.
[0031]
  In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three stages, but there is no problem even if the control is performed in two stages or more than four stages.
[0032]
  (Example 4)
  Next, a fourth embodiment of the present invention will be described. The configuration of this embodiment is the same as that of the second or third embodiment, and the control program that the control means 11 has is different.

[0033]
  The operation of this embodiment will be described below. In step 301, the start of the operation is confirmed, and in step 302, the operation time of the drying operation is started. At the same time, in step 303, the first blowing means 19, the second blowing means 20, the heating means 21, and the rotor motor 22 constituting the dehumidifying means 8 are turned on. For this reason, the air in the drying chamber 7 is dehumidified by the adsorbent 18a. Further, the adsorbent 18a generates heat of adsorption by condensation of the adsorbed water, and the air blown by the first blowing means 19 becomes high-temperature and low-humidity dry air. This dry air comes into contact with the clothes in the drying cabinet 7 and dries the clothes. The air that has become low-temperature and high-humidity including moisture released from the clothing is sent again from the intake pipe 12 to the dehumidifying means 8 and becomes dry air. Subsequently, in step 304, it is confirmed whether or not the drying operation has continued for a predetermined time. When the result of the confirmation is YES, the process proceeds to step 305, and the energization power of the first blowing means 19, the second blowing means 20 and the heating means 21 constituting the dehumidifying means 8 is reduced to a predetermined value. The power control for the second air blowing means 20 and the heating means 21 includes, for example, a method of performing phase control on a supply voltage from a commercial power source, and this embodiment does not particularly limit the energization method. .
[0034]
  The reason why the energization power to the first blowing unit 19, the second blowing unit 20, and the heating unit 21 is decreased to a predetermined value as the predetermined time elapses is the same as described in the first embodiment. That is, the moisture contained in the clothes housed in the drying chamber 7 is reduced as a predetermined time passes, and the amount of moisture released from the clothes from this stage is less than that in the initial stage of drying. Therefore, the amount of air blown by the first blower means may be small, and the amount of regeneration air blown by the second blower means 20 to regenerate the adsorbent 18a may be small. Further, if the amount of the regeneration air blown by the second blowing means 20 is controlled to be small, the amount of energization to the heating means 21 that keeps the temperature of the regeneration air at a predetermined temperature may be small. If the result of the check in step 304 is NO, the operation of each part in step 303 is continued.
[0035]
  Subsequently, in step 306, it is confirmed whether or not the drying operation has continued for a second predetermined time. If the result of the confirmation is YES, the process proceeds to step 307, and the energization amounts for the first air blowing means 19, the second air blowing means 20 and the heating means 21 constituting the dehumidifying means 8 are further reduced to the next predetermined value. Let In Step 308, it is further confirmed whether or not the drying operation has passed for a third predetermined time. If the result of the confirmation is YES, the process proceeds to step 309, and the energization amounts for the first blowing means 19, the second blowing means 20 and the heating means 21 constituting the dehumidifying means 8 are further reduced to the next predetermined value. Let
[0036]

The configuration of this embodiment is the same as that of the fifth embodiment, and the control program of the control means 11 is different. FIG. 10 is a flowchart showing a control program that the control means 11 of this embodiment has.
[0045]
  The operation of this embodiment will be described below. In step 501, the start of the operation is confirmed, and in step 502, the operation time of the drying operation is started. At the same time, in step 503, the dehumidifying means 8 and the internal circulation air blowing means 30 are turned on. That is, the air in the drying chamber 7 is dehumidified by the dehumidifying means 8 and is repeatedly blown into the drying chamber 7 from the blowing port 13a of the blower tube 13, and at the same time, the circulation fan 30 in the warehouse is in the drying chamber 7. This air is circulated in the drying chamber 7. For this reason, the dry air blown from the blower opening 13a repeatedly comes into contact with the clothes in the drying chamber 7, and the clothes in the drying chamber 7 are quickly dried.
[0046]
  When it is confirmed in step 504 that the drying operation has continued for a predetermined time, in step 505, the energization power to the first blowing means 19, the second blowing means 20 and the heating means 21 constituting the dehumidifying means 8 is set to a predetermined value. At the same time, the energization power to the circulating air blowing means 30 is increased, and the air blowing amount corresponding to the amount of decrease in the air blowing amount of the dehumidifying means 8 is increased. Subsequently, in step 506, it is confirmed whether or not the total drying time has reached the second predetermined time. If the result is YES, in step 507, the first blowing means 19 and the second blowing means 19 constituting the dehumidifying means 8 are checked. The energization power for the air blowing means 20 and the heating means 21 is further reduced to a predetermined value, and at the same time, the energization power for the circulation air blowing means 30 is increased and the air flow corresponding to the reduced air flow due to the decrease in the energization power to the dehumidifying means 8 is sent. Increase air flow. For this reason, even if the amount of dry air blown from the discharge port 9 decreases, the energization power to the circulation blower 30 is increased to increase the circulation air volume, so that the clothes in the drying chamber 7 are dried. Is something that does not change. In addition, the total power consumption is reduced by this control.
[0047]
  Next, in step 508, it is confirmed whether or not the total drying time has reached the third predetermined time. If YES, the process proceeds to step 509, where the first blowing means 19 and the second blowing means constituting the dehumidifying means 8 are processed. 20 and the heating means 21 are further reduced to a predetermined value, and at the same time, the energization power to the circulating air blowing means 30 is increased, and the amount of air sent is equivalent to the amount of air flow reduced by the decrease in the energizing power to the dehumidifying means 8. Increase airflow further.
[0048]
  Thus, when it is confirmed in step 510 that the total drying time has reached a predetermined time, energization of the dehumidifying means 8 and the internal circulation blower means 30 is stopped in step 511.
[0049]
  As described above, according to the present embodiment, the drying chamber 7 for storing clothes, the dehumidifying means 8 for sucking the air in the drying chamber 7, dehumidifying it, and discharging it again into the drying chamber, the drying chamber 7 and the dehumidifying means. An intake pipe 12 and a blower pipe 13 connected to each other, an internal circulation blower means 30 for circulating the air in the dry warehouse 7 into the dry warehouse 7, and a control means 11 for controlling the dehumidifying means 8. The control means 11 has a configuration in which the dehumidifying power of the dehumidifying means 8 is gradually reduced to reduce the amount of dehumidified air as the drying time elapses, and the circulating air quantity of the internal circulation air means 30 is gradually increased. Realize an energy efficient clothes dryer.
[0050]
  In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three stages, but there is no problem even if the control is performed in two stages or more than four stages.
[0051]

When the result of the check in step 605 is YES, the process proceeds to step 606 to reduce the power consumption of the dehumidifying means 8 and increase the energized power of the internal circulation blower means 30 to increase the consumption of the dehumidifying means 8. The air flow rate corresponding to the air flow rate decreased by reducing the electric power is increased. As the clothes in the drying chamber 7 are dried, the temperature detected by the temperature / humidity detection means 35 increases, and the humidity decreases. In this embodiment, when the temperature and humidity detected by the temperature and humidity detection means 35 reaches a predetermined value, it is determined that the drying of the clothing has progressed to a predetermined stage.
[0054]
  Next, in step 607, it is confirmed again that the operation time of the drying operation has reached a predetermined time. If the result is YES, the process proceeds to step 614 to finish drying. When it is NO, it progresses to step 608 and it is confirmed again whether the temperature and humidity of the air in the drying store | warehouse | chamber 7 reached the 2nd predetermined value. If the result of the check at step 608 is NO, the process returns to step 607 to continue the energization state of the dehumidifying means 8 and the internal circulation air blowing means 30 at step 606. If the result of the check in step 608 is YES, the process proceeds to step 609 to further reduce the energization power to the dehumidifying means 8 and at the same time increase the energization amount to the internal circulation blower means 30, The amount of air blown corresponding to the amount of air blown reduced due to the reduction of is increased.
[0055]
  Next, the process proceeds to step 610 to confirm again that the operation time of the drying operation has reached a predetermined time. If the result is YES, the process proceeds to step 614 to finish drying. If NO, the routine proceeds to step 611, where it is confirmed whether or not the temperature and humidity detected by the temperature and humidity detection means 35 has reached a third predetermined value. That is, when the temperature / humidity detected by the temperature / humidity detecting means 35 reaches the third predetermined value, it is determined that the drying of the clothing has progressed to the third predetermined stage. If the result of this check is YES, the process proceeds to step 612 to further reduce the energization power to the dehumidifying means 8 and at the same time increase the energization amount to the internal circulation blower means 30 to reduce the power consumption of the dehumidification means 8. The air flow corresponding to the reduced air flow is increased.
[0056]
  Next, the process proceeds to step 613 to confirm again that the operation time of the drying operation has reached a predetermined time. When the result is YES, the process proceeds to step 614 to turn off the dehumidifying means 8, and when the internal circulation fan 30 is in an operating state, the internal circulation fan 30 is turned off and the drying is finished. . If the result of the check at step 613 is NO, the energization state for the dehumidifying means 8 and the energization state for the internal circulation blower means 30 at step 612 are continued.
