有孔容器142通過後，藉由彈簧的力量而回復至水平位置 〇 另一方面，若按下殺菌開始開關123，計時器202設 定規定的時間例如4分鐘。該期間，加熱器·繼電器控制 部2 04對應藉由溫度感測器1 1 0所檢測出來的溫度，控制 加熱器1 3 6的開/關，使得殺菌用油1 2可以保持在設定溫 度。 一旦經過規定時間，計時器202會使聲音合成部216 發出表示殺菌完成的聲音訊息。與此同時，驅動部208控 制馬達1 4 8，將裝有器具1 4的有孔容器1 42緩慢地以大 略一定的速度自加熱槽132上升至原來的最高的高度，然 後停止。在有孔容器142自加熱槽132的位置至器具裝塡 部1 50的位置的上升期間，當通過活門板1 40的位置時， 活門板1 40被有孔容器1 42的頂部推押而往上旋轉打開’ 待有孔容器142通過後，活門板142利用彈簧的力量回復 至水平位置。 此時，有孔容器142內的器具約爲高溫的140°C，用 手觸摸非常危險。因有孔容器1 42緩慢地上升，故高溫殺 菌用油不會四處飛濺。從有孔容器】42滴落的大部分殺菌 -12- 200526278 (10) 用油最終都回到加熱槽1 3 2內。又，因具有保護罩1 62及 蓋166，故能防止發生使用者誤觸高溫的有孔容器142及 殺菌完畢的器具1 4之事故。 當有孔容器142移動至最高的高度時，藉由計時器 2 〇 2，風扇驅動部2 1 2會使風扇1 6 8動作，而有孔容器的 側部強制地冷卻有孔容器1 42，直到規定的時間例如5分 鐘經過爲止。在風扇1 6 8的外側裝設有濾網3 1 2以去除麈 埃而送入淸淨的空氣。空氣自裝設於保護罩1 62右側的開 口排出。經過規定時間後，風扇驅動部2 1 2依據來自計時 器之表示時間經過的訊號，使風扇1 6 8停止運轉，並使聲 音合成部216發出表示器具14的殺菌完成之訊息。此時 器具1 4的溫度最好在4 0 °C以下。其後，使用者只要打開 蓋166取出器具14便可以。藉由上述的強制冷卻，殺菌 完畢的器具1 4，在短時間內便成爲可以使用的狀態。 其後，使用者將電源開關1 2 5關掉。當殺菌用油1 2 污濁時’使用者只要打開排出口 1 24的閥，讓殺菌用油排 放至別的容器內便可以。

When the oil level of the sterilization oil 1 2 reaches the height of the oil level sensor 1 1 6 at the highest position, the oil level detection unit 2 06 can detect it and transmit the detection signal to the sound synthesis unit 2] 6 . Sound synthesis -10- 200526278 (8) Part 2 1 6 After receiving the detection signal, it will send out a sound message indicating that the sterilization oil 2 is full. Similarly, when the oil level of the sterilizing oil 12 is lowered to the height of the oil level sensor 1 16, the sound synthesizing unit 2 16 will emit an audio message indicating that the sterilizing oil 12 is lower than a predetermined height. If the oil level of the sterilizing oil 丨 2 drops to the height of the oil level sensor 1 1 3, the sound synthesizing section 2 1 6 will send out a voice message indicating that the sterilizing oil 1 2 has almost no sound. Oil level sensor 1 1 2, 1 1 3, 1 1 4 and 1 1 6 series electrodes, the oil level detection unit 206 measures the electrodes of the oil level sensor 1 1 2 and the oil level sensor Π 3, : The resistance between the electrodes of I 1 4 and 1 1 6 to measure the height of the sterilizing oil 12. The oil level sensors 1 1 2 and 1 1 3 can be arranged at the same height from each other. When the oil level of the sterilization oil 1 2 is higher than the height of the oil level sensor 1 1 4, the heater / relay control unit 204 supplies power to the heater 1 3 6 by relay control, and controls the sterilization oil 12 to a setting. The temperature is, for example, 1 4 0 ° C. When the temperature detected by the temperature sensor 1 1 0 reaches the set temperature, the heater / relay control unit 204 will display it on the temperature display 128, and the sound synthesis unit 216 will indicate that the current temperature has reached the set temperature. Voice message. Next, the user opens the cover 1 6 and puts the used medical device 14 such as a handpiece for dental treatment and a scalpel into the perforated container 142 at a high position, and then closes the cover 166.

The perforated container 142 is lowered from the position in the appliance mounting portion 150 to the position in the heating tank 1 32. When passing through the position of the shutter plate 1 40, the shutter plate 1 40 is replaced by the perforated container 1 42. The bottom is pressed and rotated downward to open. After the hole container 142 passes, it returns to the horizontal position by the force of the spring. On the other hand, if the sterilization start switch 123 is pressed, the timer 202 sets a predetermined time, for example, 4 minutes. During this period, the heater / relay control unit 204 controls the on / off of the heater 1 36 in response to the temperature detected by the temperature sensor 110, so that the sterilizing oil 12 can be maintained at the set temperature. Once the predetermined time has elapsed, the timer 202 causes the sound synthesizing unit 216 to emit an audio message indicating the completion of the sterilization. At the same time, the drive unit 208 controls the motor 1 48 to slowly raise the perforated container 1 42 containing the appliance 14 from the heating tank 132 to the original highest height at a substantially constant speed, and then stops.

The perforated container 142 rises slowly, so high-temperature sterilization oil does not splash around. Most of the sterilization from the perforated container] 42 drops -12- 200526278 (10) The oil finally returned to the heating tank 1 3 2. In addition, since the protective cover 162 and the cover 166 are provided, it is possible to prevent accidents in which the user accidentally touches the perforated container 142 at a high temperature and the sterilized device 14. When the perforated container 142 moves to the highest height, by the timer 2 0 2, the fan driving section 2 12 will cause the fan 16 to operate, and the side of the perforated container forcibly cools the perforated container 1 42. Until a predetermined time elapses, for example, 5 minutes. A filter screen 3 1 2 is installed on the outside of the fan 168 to remove air and send clean air. Air is exhausted through an opening provided on the right side of the protective cover 162. After the predetermined time has elapsed, the fan driving unit 2 1 2 stops the fan 16 8 according to the signal indicating the passage of time from the timer, and causes the sound synthesizing unit 216 to send a message indicating that the sterilization of the appliance 14 is completed. At this time, the temperature of the appliance 14 is preferably below 40 ° C. Thereafter, the user only needs to open the cover 166 and take out the appliance 14. By the forced cooling as described above, the sterilized devices 14 are ready for use in a short time. Thereafter, the user turns off the power switch 1 2 5. When the sterilization oil 1 2 is dirty, the user only needs to open the valve of the discharge port 1 24 and let the sterilization oil be discharged into another container.
