In the case of drum-type dryers, in order to improve drying efficiency, hot air is recently supplied into the drum from the front side, and the air is also discharged from the drum from the front side. For example, an air guide is fixedly disposed outside the entrance and exit of the material to be dried, and the front opening of the drum is rotatably supported by the outer periphery of the air guide, and an inlet and an inlet are connected to the air guide facing into the drum. An outflow port is formed, an inflow port is communicated with an outside air intake formed on the front surface of the outer box, the outflow port is communicated with an exhaust duct, and a heater is provided between the outside air intake and the inflow port. That comes to mind. However, in this case, the heater is located near the outside of the peripheral wall of the entrance and exit, and the peripheral wall of the entrance is heated by the heater.
If you touch the peripheral wall of the entrance/exit when removing clothes from the drum, you may feel hot or get burned. In order to prevent this, it would be possible to install a heat insulating material on the inner peripheral surface of the entrance/exit, but this is disadvantageous in terms of cost, and the clothing being agitated by the rotation of the drum may come into contact with the heat insulating material. This may cause the insulation material to peel off.

が多くなつて乾燥効率の向上を図り得る。 Next, the operation of the above configuration will be explained. Load the clothes into the drum 3, set the timer 33, and turn the motor 2 on.
2 and the heater 15, the blower fan 21
rotates at high speed, and the drum 3 rotates counterclockwise. As the drum 3 rotates, the clothes inside rise up while remaining in contact with the inner peripheral surface of the drum 3 on the right side of the drum 3, and when they reach near the top, the momentum of the rotation up to that point causes the clothes inside the drum 3 to move up to the left side of the drum 3. Repeat the stirring motion of loosening and falling. Also, due to the rotation of the blower fan 21, the drum 3
Since the pressure inside becomes negative, the outside air is sucked in from the outside air intake port 13 as shown by arrow A in FIG. The air is blown out from the inlet 10 toward the left side of the drum 3 toward the back. The warm air blown out from drum 3 first flows through drum 3.
In the left side of the drum 3, it collides with the continuously falling clothes while being loosened, spreads widely and flows between the clothes, absorbing the moisture, and then turns to the right as a whole and falls on the right side of the drum 3. Then, as the drum 3 rotates, the clothes rising upward are dried. The exhaust air that has removed the moisture from the clothes in this way flows into the cover 17 through the outlet 11 of the air guiding body 6 and the inside of the exhaust case 16, and further passes through the lint filter 19 from the exhaust duct 18 to the fan casing. 20 and is discharged outside the machine from the discharge port 20a. Therefore, the hot air blown into the drum 3 from the inlet 10 does not directly flow into the outlet 11, but instead changes direction within the drum 3 and flows in the radial direction, which is why the drum 3 is thin. The hot air also spreads over a wide area inside the drum 3 and stays there for a relatively long time, which in turn increases the chances of the hot air coming into contact with the clothes, improving drying efficiency.
一方、前述したように送風フアン２１の回転に

に流入した空気が冷風路３０内を流通する過程
で、出入口８の周壁部たる導風体６の矩形周壁部
６ａを冷却するので、温風路１４が矩形周壁部３
ａの近傍に配置されていて、矩形周壁部６ａを加
熱するという事情があつても、矩形周壁部６ａの
温度はそれ程上昇せず、乾燥運転終了後に衣類を
ドラム３内から取出す際、矩形周壁部６ａに触れ
たとしてもそれ程熱く感じたり、火傷を負つたり
する虞れはない。 On the other hand, as described above, since the inside of the drum 3 becomes negative pressure due to the rotation of the blower fan 21, the drum 3
Since the inside of the outer box 1, which is in communication with the inside, also becomes negative pressure,
Outside air is sucked into the outer box 1 through the intake hole 26. The air flowing in from the intake hole 26 first flows around the motor 22 to cool it, as shown by arrow B in FIGS. The air flows into the air body 6. The air flowing into the air guide body 6 flows around the ventilation case 14, flows into the cold air passage 30, and flows into the drum 3 through the ventilation holes 28, as shown by arrow C in FIG. In the process in which the air flowing into the air guide body 6 from inside the outer box 1 flows through the cold air path 30, the rectangular peripheral wall 6a of the air guide body 6, which is the peripheral wall of the entrance/exit 8, is cooled. is the rectangular peripheral wall part 3
Even if there is a situation where the rectangular peripheral wall part 6a is heated, the temperature of the rectangular peripheral wall part 6a does not rise that much, and when the clothes are taken out from the drum 3 after the drying operation, the rectangular peripheral wall part 6a is heated. Even if you touch the part 6a, it will not feel that hot and there is no risk of getting burned.
また、温風路１４を矩形周壁部６ａの一側部た

部に限られるようになる。このため、冷風路３０
によつて冷却する部分も矩形周壁部６ａの左側部
だけで済み、従つて矩形周壁部６ａの全周を取巻
くように温風路を形成するものとは異なり、矩形
周壁部６ａの全周を冷却せずとも良いので、冷風
路３０を流通させる空気量が少なくて済む。この
ことは、ヒータ１５により加熱されずにドラム３
内に直接流入する外気量を比較的少量に抑制でき
ることを意味し、冷風路３０を通じてドラム３内
に流入する外気によつてドラム３内の温度が低下
することを極力防止できることとなる。しかも、
冷却用の外気は外箱１内を通じて冷風路３０内に
流入するので、外箱１内を流れる間にドラム３及
びモータ２２等からの放熱によつて暖められるよ
うになり、外箱１内の温度上昇の抑制と共に冷却
用の外気によるドラム３内の温度低下を防止する
上で一層好都合となる。 In addition, since the hot air passage 14 is disposed outside the left side of the rectangular peripheral wall 6a,
Of these, the portion heated by the hot air path 14 is limited to the left side. For this reason, the cold air path 30
The area to be cooled by this method is only the left side of the rectangular peripheral wall 6a. Therefore, unlike the case where a hot air path is formed around the entire circumference of the rectangular peripheral wall 6a, the entire circumference of the rectangular peripheral wall 6a is cooled. Since there is no need for cooling, the amount of air flowing through the cold air path 30 can be reduced. This means that the drum 3 is not heated by the heater 15.
This means that the amount of outside air directly flowing into the drum 3 can be suppressed to a relatively small amount, and it is possible to prevent the temperature inside the drum 3 from decreasing as much as possible due to the outside air flowing into the drum 3 through the cold air path 30. Moreover,
Since the outside air for cooling flows into the cold air path 30 through the outer box 1, it is heated by the heat radiated from the drum 3, motor 22, etc. while flowing inside the outer box 1, and the air inside the outer box 1 is heated. This is more advantageous in suppressing the temperature rise and preventing the temperature inside the drum 3 from decreasing due to the outside air for cooling.
この場合、本実施例のように、外箱１内に外気

位置して形成すれば、冷風路３０内に流通させる

る上で一層効果的である。 In this case, if the intake port 26 for taking outside air into the outer box 1 is formed at a position corresponding to the motor 22 as in this embodiment, the outside air to be circulated in the cold air path 30 can be directly supplied to the motor 22. Since the outside air can be used for cooling and is warmed by cooling the motor 22, it is more effective in preventing a drop in the temperature inside the drum 3.

を奏するものである。(Effect of the invention) As explained above, in the present invention, a cold air path is formed between the hot air path and the peripheral wall of the entrance/exit of the material to be dried, so that the peripheral wall of the entrance/exit is heated by the hot air path. Even under such circumstances, the surrounding wall of the entrance and exit can be cooled by the air flowing through the cold air path, and the temperature rise can be suppressed. However, there is no risk of feeling hot or getting burned. Moreover,
Since the hot air path is located on the outside of one side of the peripheral wall of the entrance/exit, it is only necessary to cool the one side where the hot air path is installed, and the outside air is used for cooling. Since the structure is configured such that the air is once introduced into the outer box and then introduced into the drum through the cold air passage, the amount of outside air for cooling is smaller than when cooling the entire circumference of the peripheral wall of the entrance and exit. Since the outside air for use is warmed by heat radiation from the drum etc. as it passes through the outer box, it is possible to prevent the temperature inside the drum from decreasing as much as possible due to the outside air flowing into the drum through the cold air path. This has excellent effects such as being able to prevent a decrease in drying efficiency.
