Next is a book structured as above! l! 0wI will explain the operation of the embodiment. After putting clothes and other items to be dried into the rotary drum 7 from the opening 2, the door 5 is closed and the timer 50 is set. The motor 13 and the heater 26 are energized, and the motor 15 As a result, the V Rocco fans 15 and 27 are rotated, and the rotating drum 7 is rotated via the flat belt 16, and a portion 26 generates heat. The selector switch 52 is used to set the strength of the heater 260, and the push button 521
When L is being operated rapidly, all of the heaters 26 are heated, and when the push button 52) is being pressed, only a part of the heaters 26 are energized. Before setting the timer 50, depending on the amount of cloth or the type of cloth, the remaining amount is operated. The rotation of the V-Rotsuko fan 15 causes outside air to flow from the intake port 54 through the filter 53 into the outer box 1.
The air flows through the space 5.6 in the outer box 1, is sucked into the 777 casing 25 from the suction port 23&, and is blown into the duct portion 24 from the discharge port 25'b.
When passing through the duct part 24, the part 26 is heated and turned into hot air, enters the air expanding body 20 through the communication hole 25 as shown by arrow A in FIG. It is fed into the drum 7 as shown by arrow B. The hot air thus supplied into the rotary drum 7 is scooped upward in the rotary drum 7 based on the rotation of the rotary drum 70, and is allowed to fall naturally to the agitated materials to be dried and their surroundings. The drying material passes through the drying material, generates moisture and becomes humid, and is then discharged from the first exhaust port 56 and the second exhaust port 37 as shown by arrows C and D in FIG.
The air discharged from the first exhaust port 36 enters the ventilation path 431C from the ventilation path 42 via the lining 45, and then enters the second ventilation path 431C.
The air discharged from the exhaust port 37 of the heat exchanger 33 directly enters the ventilation passage 43 via the lint filter 38, and the combined air in the ventilation passage 43 passes through the ventilation duct 46 to the ventilation pipe 5 of the heat exchanger 33.
4 and flows through the first air passage a of the experimental heat exchanger 33 as shown by arrow E in FIG.

On the other hand, due to the rotation of the fan 2, outside air is sucked into the fan casing part 31 of the fan casing 30 through the air intake 29 through the fan 28, as shown by the arrow F in FIGS. 1 and 2. As such, the hot and humid air passing through the second ventilation path 1 along the heat-exchanging side 5's radiating fins 35 and flowing through the first ventilation path alj, that is, the ventilation vI54, is cooled by the outside air. The moisture contained in the air condenses on the inner surface of the ventilation pipe 34 and is removed, turning into low-temperature dry air that flows out from the upper end of the ventilation pipe 34)! The air released into the IO, passed through the first air passage a of the heat exchanger 55, and the air passed through the second air passage 1 are mixed in the duct 30, and are discharged from the exhaust port 52 into the outer box 1. released outside. On the other hand, the condensed water adhering to the inner surface of the vent pipe 34 flows down the inner surface of the vent pipe 54 and drips onto the water receiver 47, and further flows down the inside of the drain pipe 48 and exits the outer box 1 from the drain hole 49. is drained.

According to the example of the main dormitory that was established in this way, Kaiten Dohum 7
The air that has become humid by removing moisture from the material to be dried inside the heat exchanger 33 is cooled and dehumidified by the outside air flowing outside the first ventilation path a, that is, the ventilation path 1f54, that is, the outside of the ventilation pipe 34. The air passes through the air passage (a) within the duct 30, reaches a high temperature, mixes with outside air, and is discharged from the exhaust port 52, so that the moisture contained in the air that has passed through the air passage a is Air with a sufficiently low humidity is exhausted from the exhaust port 52 so that it is diluted by the outside air that has passed through the ventilation path 1, and an increase in indoor humidity during drying operation is prevented as much as possible. be done. In addition, since outside air is sucked into the space 56 of the outer box 1 through the intake port 54, the connecting portion between the cylindrical portion 8 of the end plate 8 of the rotating drum 7 & or the ventilation cylinder 40 and the ventilation duct 46 Even if humid air is leaked from the rotary drum 7 by removing moisture from the material to be dried, it will be diluted by the low-humidity outside air and the inside of the outer box 1 will always be kept at a low humidity. Therefore, outer box 1
It is also reliably prevented that the internal parts such as the changeover switch 52 in the tie device 50 deteriorate.

Furthermore, in this embodiment, the air that has passed through the air passage a of the heat exchanger 53 is discharged to the outside of the outer box 1, and the heater 26, which is a hot air generating device, is
Since the outside air sucked in from outside the outer box 1 is supplied to the outer box 1 through the space 56 inside the outer box 1, the fan V ring 25 is The duct leading to the inlet 25& can be omitted, the number of parts can be reduced compared to the conventional structure, and the configuration is simple), making assembly easy and inexpensive.

FIGS. 5 and 6 show other embodiments of the present invention, and only the parts different from those in FIGS. 1 and 2 will be described. That is, reference numeral 57 denotes an intake port provided in the intake port 540 (not shown) 30, which corresponds to the outlet end of the second air passage and communicates with the space 56 in the outer box 1. 58 is filter 5
[30s] With the decorative spring μ installed near the left side of the K pancreas 3, the air flow rate of the syRocco fan 27 is set to, for example, approximately twice the air flow rate of the V Matsuko fan 15, and the heat exchanger 33 Approximately half of the outside air that has passed through the second ventilation path a is sucked into the outer box 1 through the intake port 57, and the remaining half is mixed with the air that has passed through the first ventilation path a and is then sucked into the outer box 1 from the exhaust port 52. Outer box 1
%O] and the above-mentioned I
j! The same effect as in the example can be obtained, and outside air is drawn into the intake port 57 in the first ventilation path a.
It is preheated by removing heat from the circulating air.
The drying efficiency described above can also be further improved.

As is clear from the embodiments described above, the present invention mixes the cooled and dehumidified air in the first air passage of the heat exchanger with the cooling outside air that has passed through the heat exchange SO 20th air passage. Since the air is discharged outside the outer box, it is possible to prevent the humidity inside the room from increasing as much as possible during drying operation, and the structure is simple and can be manufactured at low cost.Furthermore, the humidity inside the outer box can be maintained low. It is possible to provide a dryer in which electrical components inside the outer box do not suffer insulation deterioration.
