[0004]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the contact between the clothes hung on the hanger and the dry air with little movement is not efficient. The reason is that the dry air that has flowed into the drying cabinet 1 flows through a place where the resistance of the suspended clothes is small, and therefore, it is difficult to contact the place where the clothes overlap. Moreover, since dry air flows in from the lower part of the drying chamber 1 and rises from the outlet 2a, clothes near the outlet 2a are easy to dry compared to the upper part, and uneven drying occurs. Since the dry air used for drying passes only where it easily passes in this way, it flows into the dehumidifying means 5 as air in a state where it can still sufficiently retain moisture from the clothes even when it flows out of the drying cabinet 1. To do. Even if this dry air is cooled by the dehumidifying means 5, a part of the heat release amount is consumed to bring it close to the temperature at which condensation occurs as moisture. The condition increases as the drying of the clothing progresses. As a result, excessive drying time was spent.
[0005]
In addition, this type of dryer, the circulation path for supplying dry air, blowing means having blower fan, dehumidifier consisting heat exchanger is constituted by a plurality of air circulation cylinder. In addition, the cooling path for blowing the cooling air to the dehumidifying means is composed of a blowing means having a blower fan, a dehumidifying means comprising a heat exchanger, and a plurality of cooling wind tunnels, so the structure is complicated and the number of parts is high and expensive. It was something.
[0006]

[0009]
[Action]
According to said 1st means, after the dry air which flowed into the drying cabinet contacts clothing, a part blows out again to a drying cabinet before flowing into a dehumidification means. The remainder flows into the dehumidifying means, and the dry air that can still contain sufficient moisture comes into contact with the clothing again and is effectively used for drying, so the humidity of the dry air increases. Therefore, a part of the dry air with high humidity flows into the dehumidifying means, and when the circulating air is cooled by the dehumidifying means, it is efficiently condensed as moisture and the dehumidifying efficiency is increased. The dry air with reduced moisture is heated by the heating means and again comes into contact with the clothes in the drying cabinet, so that drying is accelerated and the drying time is increased. And since the blower outlet of the bypass flow path of dry air is provided above the drying warehouse, contact with clothing and dry air located above is performed again. Due to reuse of dry air and diffusion effect, there is no drying unevenness and the drying time is increased.
[0010]

[0012]
The dehumidifying means 23 forms a circulation path 26 and a cooling path 27. A dry air exhaust port 28 is provided in a lower portion of the front plate 25. The flat portion 24 a of the corrugated plate 24 constituting the dehumidifying means 23 is attached to the peripheral portion of the rear wall surface 20 a of the drying cabinet 19. Reference numeral 29 denotes a heater cover which communicates with the exhaust port 28 and has a dry air blow-out port 31 and incorporates a heating unit 30. The heating unit 30 is mounted on the upper side so as not to face the exhaust port 28.
[0013]
Reference numeral 32 denotes an air guide plate having a dry air outlet 32 a and configured to communicate with the circulation wind tunnel A 21 and the circulation path 26 of the dehumidifying means 23. Reference numeral 33 denotes a cooling wind tunnel, and 34 denotes a motor, which is a drive source for the blowing means 22 including a cooling fan 35 and a circulation fan. The cooling wind tunnel 33 is configured to communicate with the cooling path 27 of the dehumidifying means 23, and the motor 34 is provided leeward of the dehumidifying means 23. 36 is a cooling wind tunnel provided below the drying cabinet 19, 37 is a cooling air inlet, 38 is a cooling air outlet, and 39 is a drying air inlet provided on the top of the drying cabinet 19. .
[0014]
As described above, the circulation path for supplying the dry air to the drying chamber 19 is constituted by the air blowing means 22, the circulation wind tunnel 21, the dehumidifying means 23, the heater cover 29, and the heating means 30, and the dry air is blown out as indicated by an arrow а. It flows into the drying cabinet 19 from 31 and 32a. On the other hand, the cooling path is constituted by the cooling wind tunnel 36, the dehumidifying means 23, the cooling wind tunnel 33, and the cooling fan 35, and flows as indicated by a broken line arrow b. 40 is a drain hole for discharging water condensed by the dehumidifying means 23, 41 is a drainage tank, 42 is a hanger pipe for applying clothes, and 43 is a door sealed by the main body 20 and packing 44.
[0015]
Next, the operation will be described. First, clothes (not shown) are hung on the hanger and hung on the hanger pipe 42. When the motor 34 and the heating means 30 are energized, the drying air is heated and sent into the circulation path and the drying cabinet 1 as indicated by an arrow а. On the other hand, the cooling air flows through the cooling path as indicated by a broken line arrow b. The dry air hits the clothing and evaporates moisture away from the clothing. A part of the dry air flowing out of the circulating wind tunnel 21 through the intake port 39 flows from above the drying chamber 19 through the dehumidifying means 23 and the rest from the blowing port 32a which is a bypass flow path.
[0016]
The dry air that has flowed into the circulation path 26 of the dehumidifying means 23 is cooled and condensed by the cooling air that has flowed into the cooling path 27 via the corrugated plate 24. The dry air whose moisture has been reduced is heated by the heating means 30 and sent again from below the drying cabinet 19 through the blowout port 31. The moisture dehumidified by the dehumidifying means 23 is discharged from the drain hole 40 and collected in the drain tank 41.
[0017]
According to this configuration, firstly, the dry air that has flowed into the drying chamber 19 comes into contact with the clothing, and then partially blows out again into the drying chamber 19 from the outlet 32 a of the bypass channel before flowing into the dehumidifying means 23. The rest flows into the dehumidifying means 23. Since the dry air that can still contain moisture is brought into contact with the clothing again and effectively used for drying, the humidity of the dry air increases. Therefore, a part of the dry air having a higher humidity than the conventional example flows into the dehumidifying means 23, and when the dry air is cooled by the dehumidifying means 23, the dehumidifying efficiency is increased because it is efficiently condensed as moisture. Further, since the dry air whose moisture has been reduced is heated by the heating means 30 and again comes into contact with the clothes in the drying cabinet 19, the drying is accelerated and the drying time is also increased.
[0018]
Secondly, since the outlet 32a of the bypass passage for the dry air is provided above the drying chamber 19, the contact between the clothes positioned above and the dry air is performed again. At the same time, the dry air flowing in from the blowout port 31 provided below the drying cabinet 19 is diffused by the dry air from the blowout port 32a. Therefore, the clothes hung by the reuse and diffusion effect of the dry air have no drying unevenness and the drying time becomes fast.
[0019]
Third, since the dehumidifying means 23 comprises the front plate 25 and the main body 20 with a single corrugated plate 24 to form a dry air circulation path 26 and a cooling air cooling path 27, the conventional dry air is dried. Since the dehumidifying means 23 is configured instead of the circulating wind tunnel A2 guided to the lower side of the cabinet, the structure is simple, the number of parts is reduced, and the cost is low.
[0020]
Fourth, since the dehumidifying means 23 is a part where the circulating air and the cooling air are in contact with each other, a sealing structure between the two airs is required. In this embodiment, the corrugated plate 24 has a flat surface portion 24a on the outer peripheral portion, and the flat surface portion 24a has a flat mounting structure with the wall surface of the box forming the drying cabinet 19, so that the sealing performance is high. The amount of dehumidification is increased without leakage of dry air flowing through the circulation path.
[0021]
Fifth, the air blowing means for dry air and cooling air is driven by a single motor 34, and the motor is provided leeward of the dehumidifying means 23. The cooling air is sucked from the air inlet 37 and directly passes through the cooling wind tunnel 36 and flows into the cooling path 27 of the dehumidifying means 23, so that it is not increased by the heat generated by the motor. Therefore, since the dry air can be efficiently cooled by the dehumidifying means 23, the dehumidifying efficiency is high.
[0022]
Next, a second embodiment will be described with reference to FIGS. In FIG. 4, reference numerals 19 to 22 and 29 to 44 are the same as those in the first embodiment shown in FIG. Dehumidifying means 45 is a hollow body integrally formed by extrusion with a metal or resin having openings at both upper and lower ends and having a plurality of partition chambers, and alternately constitutes a circulation path 45a and a cooling path 45b. 46 is an intake port for dry air provided in the circulation path 45a of the dehumidifying means 45, 47 is an exhaust port provided in the cooling path 45b, 48 is an exhaust port for dry air provided in the circulation path 45a, and 49 is a cooling port. This is a cooling air inlet provided in the path 45b.
[0023]
The upper opening of the dehumidifying means 45 is closed by the upper lid 50 and the lower opening is closed by the lower lid 51. The intake port 46 communicates with the circulation wind tunnel A 21, and the exhaust port 48 communicates with the heater cover 29. Further, the exhaust port 47 communicates with the cooling wind tunnel 33 and the intake port 49 communicates with the cooling wind tunnel 36. As described above, the circulation path for supplying dry air to the drying chamber 19 is constituted by the air blowing means 22, the circulation wind tunnel 21, the circulation path 45a of the dehumidifying means 45, the heater cover 29, and the heating means 30, and is dried as indicated by an arrow а. Air flows into the drying cabinet 19 from the outlets 31 and 32a. On the other hand, the cooling path is constituted by the cooling wind tunnel 36, the cooling path 45b of the dehumidifying means 45, the cooling wind tunnel 33, and the cooling fan 35, and flows as indicated by a broken line arrow b.
[0024]
Next, the operation will be described. Since the process of drying the clothes is basically the same as that of the first embodiment, detailed description thereof is omitted. The humid dry air flowing through the circulation path 45a of the dehumidifying means 45 is cooled and condensed by the cooling air flowing through the adjacent cooling path 45b, is discharged from the drain hole 40 as water, and is stored in the drain tank 41. The dehumidifying means 45 has a simple structure because it does not require the special dehumidifying means 5 because it constitutes the dehumidifying means 23 instead of the circulating wind tunnel A2 that guides the dry air of the conventional example to the lower part of the drying cabinet. Further, it is completed by cutting a metal or resin extruded hollow body having a plurality of partition walls into a required length and processing the intake ports 46 and 49 and the exhaust ports 47 and 48. That is, since the dehumidifying means is configured by alternately configuring the circulation path and the cooling path with one component, the configuration is very simple, the number of components can be reduced, and the cost is low.
[0025]
【The invention's effect】
As described above, according to the first means of the present invention, one of the dry air flowing out from the blowing means provided in the circulation path of the dry air is used as the bypass flow path to the drying cabinet, and the other is used as the dehumidifying means. Since the circulation path having the branch flow path is configured, the dry air that can still sufficiently contain moisture is brought into contact with the clothing again and effectively used for drying. In addition, part of the dry air with high humidity flows into the dehumidifying means, and the dehumidifying means can efficiently condense as moisture, so that the dehumidifying efficiency is high and the drying time is also fast. In addition, since the outlet of the bypass channel to the drying cabinet is located above the drying cabinet, and the outlet to the drying cabinet via the dehumidifying means is located below the drying cabinet, the clothes positioned above can be dried. Again. At the same time, there is no drying unevenness due to the diffusion effect, and the drying time is also increased.
[0026]
Further, according to the second means, for motors is provided downwind of the dehumidifier, the cooling air that has air from the dryer body outside never enhanced by heat generation of the motor. Thus because the dry air you efficiently cooled by dehumidifier, high dehumidifying efficiency.
