When the inside of the first air passage in the vicinity of the connection portion between the exhaust pipe and the exhaust pipe is to be dehumidified in the drying chamber, the air volume distribution means is adjusted so that the circulating air flows only in the first circulation passage, When performing dry dehumidification outside the drying chamber, adjust the air volume distribution means so that the circulating air flows only through the second circulation path, and when the defrosting of the heat absorber during dry dehumidification outside the drying chamber, The air volume distribution means is adjusted so that the circulating air flows through the second circulation path and the first circulation path simultaneously, or the circulating air flows only through the first circulation path when the heat absorber is defrosted. Adjusting the air volume distribution means, the drying chamber At the time of simultaneous drying and dehumidification outside the drying chamber, the exhaust pipe is installed in the first air path by adjusting the air volume distribution means so that the circulating air flows simultaneously in the first circulation air path and the second circulation path. Distributing means is also installed in the first air passage and an intake pipe is installed in the second air passage to form two circulation paths, so that one each of the air blowing means and the air passage switching means that have conventionally been required in plurality. In the drying and dehumidifying operation outside the drying chamber, frost suppression and defrosting operation of the heat absorber can be enabled.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
1 to 3 show a system diagram of a clothes drying apparatus according to the first embodiment of the present invention, and FIG. 1 shows the inside of the drying chamber of the clothes drying apparatus according to the first embodiment of the present invention. It is a system diagram at the time of dry dehumidification operation.

  In FIG. 1, a drying chamber 10 is, for example, in the form of a drum that houses and rotates clothing 11 and the like. The heat absorber 12, the radiator 13, the compressor 14, and the expander 15 constitute a heat pump means, and the pressure of the compressor 14 and the radiator 13 that radiates heat of the compressed high-temperature and high-pressure refrigerant and the high-pressure refrigerant. Is connected to a heat-absorbing device 12 that draws heat from the surroundings with a refrigerant that has been decompressed to a low pressure.

  The drying chamber 10 and the heat pump means connect the drying chamber 10 and the heat radiator 13 side of the heat pump means with a tubular first air passage 16, and the drying chamber 10 and the heat absorber 12 side of the heat pump means have a tubular second air passage 17. Connect with. A blower means 18 is sandwiched between the connection portions of the radiator 13 and the first air passage 16. The position of the air blowing means 18 is not limited to the above. The air blowing means 18 is, for example, a DC motor driven air blowing fan.

  An exhaust pipe 19 for discharging the circulating air to the outside of the apparatus is installed in the second air path 17, and the second air path 17 is opened and closed inside the second air path 17 at the connecting portion between the second air path 17 and the exhaust pipe 19. And one air volume distribution means 20 capable of controlling the position, which also functions to open and close the exhaust pipe 19 is installed. The air volume distribution means 20 is an open / close valve capable of position control in an open / close state by a stepping motor, for example.

  An intake pipe 21 is installed in the second air passage 17 that supplements the circulating air discharged from the exhaust pipe 19 and sucks outside air. The intake pipe 21 is installed between the exhaust pipe 19 and the heat absorber 12. When the air volume distribution means 20 is switched to the position a of the second air passage 17 maximum opening (exhaust pipe 19 closed), it passes through the radiator 13, the first air passage 16, the drying chamber 10, the second air passage 17, and the heat absorber 12. Thus, the first circulation path that circulates air in the order of returning to the radiator 13 can be configured, the air volume in the first circulation path is maximized, and no air volume is generated in the second circulation path. FIG. 1 shows a flow of the first circulation path at this time as a circulation wind A.

  According to such a configuration, when clothing 11 is placed in the drying chamber 10, the high-temperature and low-humidity air obtained from the radiator 13 strikes the clothing 11, deprives moisture into high-temperature and humid air, and circulates to the heat absorber 12 to generate heat. Is taken away, and moisture in the air condenses, allowing dry dehumidification. By repeating this circulation, the clothes 11 in the drying chamber 10 are dried.

  FIG. 2 is a system diagram at the time of the drying and dehumidifying operation outside the drying chamber of the clothes drying apparatus according to the first embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted. In FIG. 2, for example, clothes 22 outside the drying chamber are suspended above the clothes drying apparatus. The object to be dried and dehumidified is not limited to clothes hung upward, and may be for the purpose of air conditioning near the installation location.

  When the air volume distribution means 20 is adjusted to the position b where the second air passage 17 is closed (exhaust pipe 19 maximum opening), the intake pipe 21, the second air path 17, the heat absorber 12, the radiator 13, the first air path 16, A second circulation path that circulates air in the order of returning to the intake pipe 21 through the drying chamber 10, the second air path 17, the exhaust pipe 19, and the space outside the apparatus can be configured, and the air volume in the second circulation path is maximized. No airflow is generated in one circulation path. In FIG. 2, the flow in the second circulation path at this time is shown as circulation wind B.

  According to this configuration, high-temperature and low-humidity air is sent out from the radiator 13, passes through the first air passage 16, passes through the drying chamber 10, and is discharged from the exhaust pipe 19, for example, outside the drying chamber suspended above the clothing drying device By taking moisture away from the clothes 22, the air that has become humid is sucked from the intake pipe 21, deprived of heat by the heat absorber 12 through the second air passage 17, and by repeating this circulation, The clothes 22 outside the drying room can be dried and dehumidified.

  During the drying and dehumidifying operation outside the drying chamber, it is necessary to remove the clothing 11 from the drying chamber 10 when the clothing 11 contains moisture. Since the circulation air is sent out from the exhaust pipe 19 to the outside of the apparatus after passing through the drying chamber 10, if there is clothing 11 containing moisture in the drying chamber 10, the circulating air containing moisture taken from the clothing 11 is supplied to the device. Since it goes outside, it is impossible to take moisture in the air outside the drying chamber, and drying and dehumidification outside the drying chamber cannot be performed.

  When the amount of air discharged from the exhaust pipe 19 to the outside of the clothes drying device is compared with the amount of indoor air, for example, where the clothing drying device is installed, the amount of indoor air is significantly large and the intake pipe 21 sucks. The temperature of the air strongly depends on the temperature of the air in the room, and the intake pipe 21 sucks the air slightly raised from the room temperature and circulates it to the heat absorber 12. The room temperature of a normal house is considered to change around 5 ° C to 40 ° C. Therefore, for example, if an attempt is made to perform a dehumidifying operation outside the drying room from 5 ° C., depending on the humidity, the heat absorber 12 may be lowered below the freezing point in order to condense moisture. Frost is generated on the surface of the heat absorber 12.

  FIG. 3 is a system diagram of the frost suppression operation state during the drying and dehumidifying operation outside the drying chamber of the clothes drying apparatus according to the first embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 3, the air volume distribution means 20 is controlled to the position c so that the air volume flowing from the drying chamber 10 is, for example, 1: 5 on the second air path 17 side and the exhaust pipe 19 side. A first circulation path that circulates air in the order of returning to the radiator 13 through the first air path 16, the drying chamber 10, the second air path 17, and the heat absorber 12, and the intake pipe 21, the second air path 17, and the heat absorption The second circulation path that circulates air in the order of returning to the intake pipe 21 through the outside space of the apparatus 12, the radiator 13, the first air path 16, the drying chamber 10, the second air path 17, the exhaust pipe 19, and the external space it can. In this case, the air volume ratio of the first circulation path and the second circulation path is distributed 1: 5 between the branch portion of the second air path 17 and the exhaust pipe 19 to the connection portion of the intake pipe 21 and the second air path 17. Is done. FIG. 3 shows the circulation wind C of the first circulation path at this time as the circulation wind D of the second circulation path.

  According to such a configuration, the ratio of the amount of air flowing through the first circulation path and the second circulation path is controlled to 1: 5 by the air volume distribution means 20, and the heat absorber 12 is not exhausted to the outside air. The circulation which returns is performed, The temperature of the air which goes to the heat absorber 12 is raised by this circulation, and the state where it is hard to attach frost to the heat absorber 12 can be created. The air volume distribution of the first circulation path and the second circulation path is not limited to 1: 5.

  However, as a result of controlling the air volume distribution means 20 to suppress frost, the air volume distribution ratio of the first circulation path and the second circulation path is given priority to the first circulation path, and finally the first circulation path of FIG. It is possible that the circulation of the second circulation path does not occur. In this state, even if the heat absorber 12 is frosted, the circulating air is supplied to the heat absorber 12 so that defrosting can be performed quickly. In the defrosting operation, the rotation of the compressor 14 of the heat pump means may be stopped and the first circulation path may be circulated only by the air blown by the blower means 18. The compressor 14 of the heat pump means is stopped, the high-temperature refrigerant on the radiator 13 side flows to the heat absorber 12 side, the temperature of the heat absorber 12 rises, and the air at a temperature higher than the freezing point sent by the blower means 18 is used. The frost attached to the heat absorber 12 can be removed.

  As can be seen from the above, the air volume distribution ratio of the first circulation path and the second circulation path is determined by the atmosphere of the clothes drying chamber apparatus, the state of the air flowing through the circulation path, the surface temperature of the heat absorber 12 and the heat pump unit. It is desirable to determine from the refrigerant temperature and pressure. For example, in FIGS. 1-3, the state detection means 25 which consists of a thermistor is installed in the 2nd wind path 17 and the 2nd wind path 17 of an intake pipe 21 connection part, and the circulation path control means 26 which is a control circuit is installed. The detection result of the state detection unit 25 is processed by the circulation path control unit 26 to control the compressor 14 and the air volume distribution unit 20 of the heat pump unit.

  According to such a configuration, the temperature in the vicinity of the heat absorber estimated from the temperature detection for adjusting the temperature in the circulation path in the drying dehumidification in the drying chamber and the relationship between the outside air temperature and the refrigerant temperature of the heat pump means in the drying dehumidification outside the drying chamber. The state detection means 25 can be used only for the state detection means 25. In the drying and dehumidifying operation in the drying chamber of FIG. 1, the circulating air flows only in the first circulation path, so the state detection means 25 sets the circulating air temperature from the drying chamber 10 toward the heat pump means. The circulation path control means 26 detects the circulating air by reducing the rotational speed of the compressor 14 if the circulating air temperature rises, and increasing the rotational speed of the compressor 14 if the circulating air temperature falls. It becomes possible to keep it constant.

  In the drying and dehumidifying operation outside the drying chamber in FIG. 2, since the circulating air flows only in the second circulation path, the state detection means 25 detects the outside air temperature sucked by the intake pipe 21, and the circulation path control means 26 is the compressor of the heat pump means. By performing the control 14, the circulating air can be kept constant.

  Further, when the detection result of the state detection means 25 of the outside air temperature sucked into the intake pipe 21 becomes equal to or lower than a predetermined temperature such as 5 ° C., the circulation amount control means 26 sets the air volume distribution means 20 in FIG. It becomes possible to suppress the generation of frost in the heat absorber 12 while controlling the position c to perform drying and dehumidification outside the drying room. Alternatively, the circulation path control means 26 controls the air volume distribution means as shown in FIG. 1 to the position a, stops the compressor 14 of the heat pump means, and flows the circulation air only to the first circulation path to the heat absorber 12. The generated frost can be defrosted.

  Since the state detection means 25 estimates the surface temperature of the heat absorber 12 from the relationship between the outside air temperature and the refrigerant temperature of the heat pump means based on the outside air temperature sucked by the intake pipe 19, an estimation error may occur. Therefore, for example, when the surface temperature state of the heat absorber 14 is detected by installing the heat absorber state detection means 27 made of the thermistor on the surface portion of the heat absorber 12 of the heat pump means and detecting the surface temperature of the heat absorber 14, the heat absorber. 14 The generation of frost attached to the surface can be estimated more accurately.

  The heat absorber state detection means 27 may be installed on the wind of the heat absorber 14 to detect the temperature of the circulating air toward the heat absorber 14.

  The heat absorber state detection means 27 may be installed between the heat sink 14 and the heat radiator 13 so as to detect the temperature of the circulating air that exits the heat absorber 14 toward the heat radiator 13.

  The heat absorber state detection means 27 may be installed on the surface of the pipeline through which the refrigerant connected to the heat absorber 14 circulates to detect the temperature of the refrigerant as the surface temperature of the pipeline.

  1 to 3, in order to operate the present invention in a sanitary manner with no performance degradation, the second air passage 17 and the connection portion between the intake pipe 21 and the heat pump means are located inside the second air passage 17 at a position between them. One filter 23 is installed, and one second filter 24 is installed inside the second air passage 17 at a position before reaching the exhaust pipe 19 from the drying chamber 10.

  With this configuration, the first filter 23 collects dust outside the apparatus sucked by the intake pipe 21, and the second filter 24 prevents lint from the clothes 11 inside the drying chamber 10 from being discharged from the exhaust pipe 19 to the outside. By preventing lint and dust from entering the heat pump means and the air blowing means 18, the performance of the heat pump means and the air blowing means 18 is prevented from being deteriorated due to adhesion of the lint and dust, and the lint is discharged out of the apparatus and in the vicinity of the apparatus installation location. Dirt due to lint scattering can be prevented.

  The air volume distribution means 20 may be controlled by combining a DC or AC motor and a potentiometer.

  It is to be noted that an instruction control means (not shown) for instructing switching between drying dehumidification in the drying chamber and drying dehumidification outside the drying chamber is provided, and based on the operation of the operator, it is more easy to use if it corresponds to the operation intended by the operator. Increase.

  With the clothes drying apparatus configured as described above, drying dehumidification inside the drying chamber and drying dehumidification / dehumidification outside the drying chamber can be performed by one each of the air blowing means 18 and the air volume distribution means 20. The frost suppression and defrosting operation of the heat absorber 12 are also possible.

  1 to 3, a water storage outer tank 28 containing the drying chamber 10, a drainage path 30 having a drain valve 29 for draining washing water into the outer tank, and water from an overflow port 31 from the outer tank 28. By providing the overflow path 32 that drains the washing water before it overflows, it can be used as a clothes drying device with a washing function. Put clothes to be washed in the drying chamber 10 in advance and hang them outside the clothes drying chamber to be dried. In this case, the clothes 11 in the drying chamber 10 can be sequentially washed and dried, and then the clothes 22 outside the drying chamber can be dried.

The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. FIG. 4 is a system diagram at the time of the drying and dehumidifying operation in the drying chamber of the clothes drying apparatus according to the second embodiment of the present invention.

  In FIG. 4, an exhaust pipe 33 that discharges a part of the circulating air to the outside of the apparatus is installed in the first air path 16, and the first air path 16 at the connection portion between the first air path 16 and the exhaust pipe 33 is provided with One air volume distribution means 34 is installed which has the function of opening and closing one air passage 16 and opening and closing the exhaust pipe 33.

  When the air volume distribution means 34 is switched to the position d of the first air passage 16 maximum opening (exhaust pipe 33 closed), it passes through the radiator 13, the first air passage 16, the drying chamber 10, the second air passage 17, and the heat absorber 12. Thus, the first circulation path that circulates air in the order of returning to the radiator 13 can be configured, the air volume in the first circulation path is maximized, and the air volume in the second circulation path is not generated. FIG. 4 shows the flow of the first circulation path at this time as a circulation wind E.

  According to this configuration, when clothing 11 is placed in the drying chamber 10, high-temperature and low-humidity air obtained from the radiator 13 hits the clothing 11, deprives moisture into high-temperature and high-humidity air, and circulates to the heat absorber 12. Drying and dehumidification become possible by removing heat and condensation of moisture in the air. By repeating this circulation, the clothes 11 in the drying chamber 10 are dried.

  FIG. 5 is a system diagram at the time of the drying and dehumidifying operation outside the drying chamber of the clothes drying apparatus according to the second embodiment of the present invention.
