（イ）産業上の利用分野
本発明は、布団乾燥機の改良に関し、特に高級布団と呼
ばれる羽毛布団の乾燥を行うものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an improvement of a futon dryer, and is particularly for drying down comforters called high-quality futons.
（ロ）従来の技術
布団乾燥機は、綿の生地よりなる掛布団と敷布団との間
に介装した通気性のシートに温風を送り、それぞれの布
団を乾燥するものであるが、送風器本体の温風温度は一
定となっている。すなわち、単に商用電源間にタイマー
スイッチと直列にヒータとファンモータの並列回路を接
続しただけであり、布団の内部の乾燥温度については何
ら配慮されていなかった。（実公昭５８−１４９５８号
公報参照）
ところが、最近の高級化志向から羽毛布団が用いられる
ようになり、この羽毛布団も乾燥する必要を生じたが、
羽毛布団は高密度に製織された生地を使用しており良質
な状態で長期間使用する場合には湿度、温度を十分に注
意する必要があり、この点からしても羽毛布団の乾燥は
不可能となった。(b) Conventional technology Futon dryers dry each futon by blowing warm air through a breathable sheet interposed between a comforter made of cotton fabric and a mattress. The hot air temperature is constant. That is, a parallel circuit of a heater and a fan motor was simply connected in series with a timer switch between commercial power sources, and no consideration was given to the drying temperature inside the futon. (Refer to Utility Model Publication No. 58-14958) However, with the recent trend toward luxury, down comforters have come into use, and these down comforters also need to be dried.
Duvets are made of densely woven fabric, and if they are to be used for a long period of time in good quality, it is necessary to pay close attention to the humidity and temperature. It has become possible.
もし、仮に、羽毛布団を他の一般の綿布口と同じ温度で
乾燥を行った場合には羽毛布団の内面の温度が連続して
５０度以上となり、また本来の適正水分である１２．５
％から極端に０％となり、この繰り返しによって生地が
劣化した。If the duvet were to be dried at the same temperature as other ordinary cotton cloths, the inner surface temperature of the duvet would be continuously over 50 degrees, and the moisture content would be 12.5 degrees.
% to 0%, and repeating this process caused the fabric to deteriorate.
また、最近、布団乾燥を行いながら同時に布団内に発生
したダニ等の害虫を駆除する害虫駆除機能を備えたもの
があるが、害虫駆除温度としては線温度が５０度以上が
適当とされているものの、この時の布団外面（布団カバ
ー）の温度は６０度程度となっている。このような温度
設定の状態で羽毛布団を数時間連続して乾燥及び害虫駆
除を行なった場合には羽毛布団の内部も５０度以上とな
り所定時間この状態が継続することからＭ述の単なる乾
燥の場合に比べて生地の傷みが激しく羽毛本来の特性で
ある吸湿性、放湿性、弾性嵩回復率が急激に低下し全く
使用に適さないものとなった。In addition, recently, there are products that have a pest extermination function that exterminates pests such as mites that have grown inside the futon while drying the futon, but a line temperature of 50 degrees or higher is considered to be suitable for exterminating pests. However, the temperature of the outer surface of the futon (futon cover) at this time was about 60 degrees. If a duvet is dried and pests are exterminated for several hours continuously under such temperature settings, the inside of the duvet will also reach over 50 degrees and this state will continue for a certain period of time. The fabric was more severely damaged than in the case of feathers, and the inherent characteristics of feathers, such as moisture absorption, moisture release, and elastic bulk recovery rate, rapidly decreased, making the fabric completely unsuitable for use.
因みに、羽毛布団のもう１つの特性として、羽毛布団は
その製造時に羽毛を１００度以上の高熱殺菌処理をして
おり、その結果、羽毛内部よりダニが発生することがな
いとされている。従って、羽毛を用いた布団にダニが付
着、発生する部分は羽毛のカバーや布団カバーであり他
の布団から移動して付着するものがほとんどである。Incidentally, another characteristic of duvets is that the down duvets are sterilized at a high temperature of 100 degrees or higher during manufacturing, and as a result, it is said that no dust mites will form inside the down duvets. Therefore, the areas where dust mites attach and occur on futons made of down feathers are the feather covers and duvet covers, and most of the dust mites migrate from other futons and attach thereto.

とする。(D) Means for Solving the Problems The present invention includes a heater, a fan motor for blowing air to the heater, a changeover switch, a pest extermination switch, and a control circuit for the heater, and the changeover switch has at least a temperature control circuit. It has a first position where the air temperature is set high and a second position where the hot air temperature is set lower than the hot air temperature set by the first position,
In the second position, when the pest extermination switch is operated, the control circuit controls the heater so that the outer surface of the futon is at the pest extermination temperature and the inner surface of the futon is below the deterioration temperature.

When the duvet is switched to this position, it is in a state suitable for drying the duvet, and the control circuit can exterminate dust mites that have adhered to or generated on the duvet's surface at a temperature that does not cause the inner surface of the fabric to reach high temperatures.

る。On the other hand, a thermistor (
Since the resistance value of the detection transistor (15) is large, the resistance value of the detection transistor (30
) turns on and starts charging the electrolytic capacitor (35) via the bias resistor (31), but during this charging, the switching transistor (34) is turned on and the inverting input terminal (P ) trigger circuit (18) at the relatively low intersection of the sawtooth wave.
is driven to turn on the triac (11) and energize the heater (10). Eventually, even if the temperature of the hot air rises and the resistance value of the thermistor (15) decreases, the switching transistor (33) is kept in the ON state until the electrolytic capacitor (35) reaches a predetermined potential, and is turned OFF when the electrolytic capacitor (35) reaches the predetermined potential. to control the heater (10). At this time, the average temperature of the sheet surface is about 60 degrees, and the temperature range below 20 degrees is determined by the constants of the bias resistor (31) and the electrolytic capacitor (35), and is set to about 10 degrees in this embodiment. (Refer to Fig. 4 ■) If the pest extermination switch (5) is now turned on in the above-mentioned state, the resistor (24) will be short-circuited and the detection transistor (30) will be short-circuited.
) is extremely low, so the transistor is turned on.
The state continues, and the heater (10) becomes continuously energized, and the average temperature of the sheet surface at this time remains constant at about 65 degrees, but the inside of the "cotton" futon also reaches about 60 degrees or higher, and dust mites spread throughout the "cotton" fabric. The extermination temperature will be . (Refer to Figure 4) Next, when drying the down comforter, switch the changeover switch (4) to the second position, connect the common contact (4a) and the second terminal (4c), and connect the resistor ( 26) to slightly reduce the resistance value on the negative side of the bridge circuit (29), and rotate the timer knob (3) to drive the timer motor (9).The subsequent operation is the switching described above. The control is similar to that in the first position of the switch (4), but the short circuit of the resistor (25) causes the detection transistor (3
Because the base potential of 0) is low, the average hot air temperature drops to about 45 degrees, and the upper and lower temperature range is set to 10 degrees, but the internal temperature of the "down" comforter does not reach the mite extermination temperature. However, since the internal temperature of the futon does not rise, the humidity inside the futon can be maintained at about 5% without any temperature effect on the fabric, even if electricity is continuously applied for 3 hours, for example. (See Figure 4 ■) When the changeover switch (4) is in the second position and the pest extermination switch (5) is turned on, the resistor (24) is short-circuited and the base potential is reduced only by the resistor (25). Therefore, the average hot air temperature rises to about 50 degrees, and the upper and lower temperature range is set to 10 degrees. In this case, the surface cover (not shown) of the "down" comforter reaches a temperature of approximately 50 to 55 degrees, which can be used to exterminate pests, but the internal temperature of the down comforter is the temperature at which the fabric deteriorates (approximately 50 degrees or higher). When this does not occur, the heater (10) is controlled by stopping energization. (Refer to FIG. 4) (G) Effects of the Invention As described above, the present invention provides a changeover switch in the second position where the hot air temperature is lower than the hot air temperature in the first position.
By operating the pest extermination switch, the heater is controlled so that the outer surface of the futon is at the pest extermination temperature and the inner surface of the futon is below the material deterioration temperature. The interior of the futon can be dried by lowering the temperature while raising the temperature to exterminate pests that have grown on the surface. Therefore, the fabric of the duvet can be used for a long period of time without deteriorating its quality.
