Definitions

  • the present invention relates a clothes dryer that dries clothes and a washer-dryer having a washing function and a clothes drying function.
  • drying air is caused to pass through an air passage to send the air into a drum.
  • the drying air is brought into contact with clothes put in the drum to extract moisture from the clothes to dry the clothes.
  • a configuration that discharges the moist drying air having a high humidity to an air passage arranged outside the drum is further arranged (see, for example, Patent Literature 1).
  • FIG. 7 is a sectional side view showing a schematic configuration of a conventional drum type washer-dryer.
  • the conventional drum type washer-dryer includes two air passages, i.e., first air passage 9 and second air passage 11 as air passages to feed drying air into drum 1 that stores clothes.
  • the drum type washer-dryer includes discharge port 5 that discharges high-humidity drying air obtained such that drying air fed into drum 1 removes moisture of clothes to blower unit 4 having circular air passage 13.
  • the drum type washer-dryer includes discharge temperature detecting unit 172 arranged at the discharge port and inflow temperature detecting unit 171 arranged on circular air passage 13 communicating with first air passage 9.
  • the drum type washer-dryer includes a configuration in which, on the basis of a temperature of drying air detected by discharge temperature detecting unit 172 or a temperature difference between a temperature of drying air detected by inflow temperature detecting unit 171 and the temperature detected by discharge temperature detecting unit 172, the two air passages including first air passage 9 and second air passage 11 are switched by air passage switching unit 12.
  • the conventional drum type washer-dryer has a configuration in which warm wind including drying air is brought into direct contact with the clothes in drum 1. For this reason, since the warm wind is not brought into uniform contact with the clothes in drum 1, the clothes are easily unevenly dried.
  • window glass 36 Since high-temperature and high-pressure drying air is blown from first air outlet 8 of first air passage 9 formed near window glass 36 configuring door 35 in front of drum 1 to clothes, window glass 36 has a high-temperature. For this reason, the temperature of window glass 36 must be decreased before the clothes are picked up.
  • FIG. 8 is a time chart showing an example of a relationship between a transition of a window glass temperature in a drying operation in the conventional drum type washer-dryer and timings at which the window glass is cooled.
  • window glass 36 is cooled with blowing or the like. For this reason, an increase in drying operation time of the drum type washer-dryer and an increase in power consumption occur.
  • a temperature of window glass 36 widely varies depending on timings at which clothes are picked up or quantities of clothes. For this reason, for example, in the case where window glass 36 is excessively cooled, in order to restart the drying operation after the clothes are picked up and put in, heating unit 7 must be warmed again. As a result, an excessive operation time and an excessive power consumption are required.
  • the conventional drum type washer-dryer has a problem in which door 35 having window glass 36 cannot be opened to pickup clothes from drum 1 in the middle of a drying operation or immediately after the drying operation. Furthermore, by a cooling time of the cooling process, re-heating of the heating unit, and the like, problems are posed in terms of shortening of a drying time, a reduction in power consumption, and the like.
  • a clothes dryer includes a drum that agitates clothes, a window glass arranged in front of the drum, a blower unit that sends drying air, a dehumidification unit that dehumidifies the drying air, and a heating unit that heats the dehumidified drying air.
  • the clothes dryer includes a first air passage having a first air outlet opened at a rear of the drum , a second air passage having a second air outlet opened in front of the drum and , an air passage switching unit that switches the first air passage and the second air passage, a temperature detecting unit that detects a temperature of the window glass, and a control unit.
  • the control unit performs control to selectively switch the first air passage and the second air passage through the air passage switching unit when a detection result of the temperature detecting unit reaches a first predetermined temperature.
  • the clothes can be dried while controlling the temperature of the window glass to the first predetermined temperature or less at which a user does not feel hot when touching the window glass.
  • a time required to cool the window glass is not required, and the clothes can be immediately picked up at any time.
  • a power consumption in a cooling process for cooling that is required in a conventional technique is made unnecessary, a power consumption can be reduced.
  • the washer-dryer according to the present invention includes at least the clothes dryer having the above configuration and a water tank that includes a drum and stores washing water.
  • a clothes dryer and a washer-dryer according to an exemplary embodiment of the present invention will be described below with reference to the accompanying drawings.
  • the exemplary embodiment (will be described below) is an example obtained by embodying the present invention and does not limit the technical scope of the present invention.
  • a drum type washer-dryer will be described as the clothes dryer and the washer-dryer, the present invention is not limited to the drum type washer-dryer, as a matter of course.
  • a drum type washer-dryer according to an exemplary embodiment of the present invention will be described below with reference to FIG. 1 .
  • FIG. 1 is a sectional side view showing a schematic configuration of a drum type washer-dryer according to an exemplary embodiment of the present invention.
  • bottomed cylindrical drum 1 having an opening in a front surface for storing laundries and a bottom part is supported in housing 100 and included in bottomed cylindrical water tank 2 for storing washing water.
  • drum drive motor 3 drum drive unit
  • drum drive unit that obliquely rotates a rotating shaft of drum 1 such that a front side of the rotating shaft is kept up.
  • Housing 100 has door 35 facing an opening end side of drum 1 and window glass 36 arranged to face drum 1 on the internal side of door 35. A user opens door 35 to make it possible to put or pick up laundries (clothes) in/from drum 1.
  • a mechanism that inhibits the door from being opened during an operation for safety for example, a door lock unit (not shown) is arranged.
  • the door lock unit is configured not to be canceled when, in a rotation period of drum 1 or a drying operation, the temperatures of the interior of drum 1, the laundries, and window glass 36 are so high that a user may be burned when touching them.
  • a water supply pipe (not shown) in which a feed valve is arranged and drain pipe 40 in which drain valve 27 is arranged are connected.
  • the drying air to dry clothes is sent into drum 1 through blower unit 4.
  • the sent drying air removes moisture from laundries in drum 1 and becomes humid.
  • the humid drying air is discharged out of drum 1 through discharge port 5 arranged at a position of a side-surface periphery of drum 1.
  • the discharged drying air is dehumidified with dehumidification unit 6.
  • the drying air dehumidified with dehumidification unit 6 is heated with heating unit 7.

  • the air-passing sectional area of first air outlet 8 of first air passage 9 is formed to be larger than the air-passing sectional area of second air outlet 10. In this manner, high-flow-rate drying air can be blown into drum 1 while keeping a pressure loss smaller than that of second air passage 11.
  • an air-passing sectional area of second air outlet 10 of second air passage 11 is formed to be smaller than an air-passing sectional area of first air outlet 8. For this reason, drying air of the speed of which is relatively higher than that in first air outlet 8 can be blown into drum 1.
  • a bottom part at the rear of drum 1 has a space in which first air outlet 8 having a relatively large opening can be arranged.
  • first air outlet 8 having a relatively low pressure loss is formed in a bottom part at the rear of drum 1.
  • cover 26 having a large number of small-diameter vent holes through which air can be passed and a high open area ratio to make it possible to prevent the clothes (laundries) from being caught by first air outlet 8.
  • drum type washer-dryer when clothes are agitated by rotating drum 1 having the rotating shaft obliquely arranged to keep the front side up, for example, small clothes such as socks, a handkerchief, and a brief are easily unevenly distributed at a rear part of drum 1.
  • small clothes such as socks, a handkerchief, and a brief are easily unevenly distributed at a rear part of drum 1.
  • large-sized clothes such as long-sleeved underwear, long-sleeved dress shirts, and long-sleeved pajamas are easily unevenly distributed at the front part of drum 1.
  • air passage switching unit 12 is arranged at a branch part between first air passage 9 and second air passage 11 formed on the downstream side of blower unit 4, and, depending on conditions such as quantities of clothes and types of clothes, a path of drying air is switched to any one of first air passage 9 and second air passage 11.
  • air passage switching unit 12 includes valve 12a pivotally supported by the branch part between first air passage 9 and second air passage 11 and a drive unit (not shown) that pivotally drives valve 12a.
  • first air passage 9 opens to cause drying air sent by blower unit 4 to pass through first air passage 9.
  • second air passage 11 opens to cause drying air sent by blower unit 4 to pass through second air passage 11. That is, valve 12a configuring air passage switching unit 12 is rotated to the a-side or b-side to make it possible to switch the path of the drying air to first air passage 9 or second air passage 11.
  • circular air passage 13 has blower unit 4 and air passage switching unit 12 that are arranged in the middle of circular air passage 13.
  • Circular air passage 13 sends drying air from first air outlet 8 or second air outlet 10 communicating with first air passage 9 or second air passage 11 switched by air passage switching unit 12 again into drum 1 sequentially through the air passages such as drum 1, discharge port 5, dehumidification unit 6, heating unit 7, and the like. In this manner, the drying air can be circulated in the drum type washer-dryer.
  • Blower unit 4 includes blower fan 4a and blower fan motor 4b and is arranged between heating unit 7 and air passage switching unit 12. Blower fan motor 4b drives blower fan 4a to send drying air heated with heating unit 7 to a downstream side (air passage switching unit 12 side) of circular air passage 13.
  • blower unit 4 rotates blower fan 4a such that a flow rate of drying air passing through first air passage 9 is a predetermined flow rate higher than a flow rate of drying air passing through second air passage 11.
  • blower unit 4 rotates blower fan 4a such that a wind speed of drying air passing through second air outlet 10 of second air passage 11 is a predetermined wind speed higher than a wind speed of drying air passing through first air outlet 8.
  • blower fan 4a is rotated such that a wind speed of drying air passing through second air outlet 10 is about 50 m/s.
  • the wind speeds of drying air passing through first air outlet 8 and second air outlet 10 are not limited to the above wind speeds.
  • the wind speeds can be set to arbitrary wind speeds as long as the wind speed of drying air in second air outlet 10 is higher than the wind speed of drying air in first air outlet 8.

  • air passage switching unit 12 is controlled to switch first air passage 9 and second air passage 11.
  • discharge port 5 that discharges drying air in drum 1 is arranged at a position having a distance from first air outlet 8 that is relatively longer than a distance from second air outlet 10. More specifically, discharge port 5 is arranged at a position that is relatively close to second air outlet 10 and far from first air outlet 8. Thus, discharge port 5 is arranged to be closer to the front part of drum 1 than the rear part thereof. Discharge port 5 may be arranged near second air outlet 10 formed in the front part of drum 1 such that the distance from first air outlet 8 is maximum.
  • Discharge port 5 is arranged above drum 1 to effectively discharge drying air that is in contact with clothes from above.
  • discharge port 5 may be arranged at a position except for the position above drum 1.
  • discharge port 5 is preferably arranged above a water level of the washing water.
  • Second air outlet 10 is formed to have an opening in a front upper part of drum 1. At this time, even though discharge port 5 is formed near second air outlet 10, while drying air is sent from second air outlet 10, relatively high-speed drying air is blown from second air outlet 10 into drum 1. For this reason, the drying air blown at a high speed is not discharged from discharge port 5 but is sent to a position far from discharge port 5 in drum 1. In this manner, the drying air can be effectively blown to clothes agitated by a raising operation caused by rotation of drum 1 to make it possible to dry the clothes. As a result, the clothes (laundries) can be efficiently dried while being suppressed from being unevenly dried.

As a result, the door lock unit is canceled without a cooling process for cooling window glass 36 by temporarily stopping the drying operation in the middle of the drying operation, making it possible to immediately pick up clothes from drum 1 at any time.
  • a power consumption can be reduced because a power consumption required to cool window glass 36 is not needed.
  • window glass 36 need not be cooled, clothes that have a high ratio of synthetic fiber and are easily dried can be easily picked up even in the middle of the drying operation. As a result, the clothes that can be easily dried can be prevented from being over dried.
