    • Disclosed is an indoor unit having a dust storage container in which dust removed from an air filter is stored, and a dust collecting box into which the dust in the dust storage container is transferred by utilizing an effect of blown air. The dust storage container is provided with a full condition detection means for detecting a dust full condition of the dust collecting box. The full condition detection means includes an LED and a phototransistor which are opposed to each other with a storage portion interposed therebetween. After a dust transfer operation which transfers the dust from the dust storage container to the dust collecting box, an intensity of light of the LED that has passed through the storage portion is detected by the phototransistor. If the detected light intensity is equal to or less than a set value, a full condition of the dust collecting box is detected.
    • 公开了一种室内机,其具有存储有从空气过滤器除去的灰尘的灰尘储存容器,以及利用吹风的作用将贮尘容器中的灰尘转移到其中的灰尘收集箱。 灰尘储存容器设置有用于检测灰尘收集箱的灰尘充满状态的全状态检测装置。 全状态检测装置包括彼此相对的LED和光电晶体管,存储部分插入其间。 在将灰尘从贮尘容器传递到集尘盒的尘埃转移操作之后,通过光电晶体管检测出通过存储部分的LED的光强度。 如果检测到的光强度等于或小于设定值,则检测到灰尘收集箱的完整状态。

    • An axial piston machine which has an even number of piston cylinder chambers housing therein pistons in relation of being movable in reciprocation respectively so as to control a stroke of the piston by a swash plate, wherein first and second compensating pistons opposite to the swash plate are provided at the symmetrical positions with respect thereto in the vicinity of the upper dead and lower dead points inclusive, so that, when one piston cylinder chamber is positioned in the vicinity of the upper or lower dead point, control pressure at the pressurized side is introduced to the second compensating piston at the lower dead point side, or that at the pressure-reduction side to the first compensating piston at the upper dead point side, thereby reducing an exciting force caused by an abrupt pressure change in the piston cylinder chamber and a large variation in the inclined moment of the swash plate, so as to enable reduction in generation of vibrations and noises.
    • 一种轴向活塞机,其具有容纳活塞的偶数活塞缸室,其分别可往复运动,以便通过斜盘来控制活塞的行程,其中与斜盘相对的第一和第二补偿活塞是 设置在相对于上死点和下死点附近的对称位置处,使得当一个活塞缸室位于上死点或下死点附近时,加压侧的控制压力被引入 到下死点侧的第二补偿活塞,或者在上死点侧的第一补偿活塞的减压侧,从而减少由活塞缸室的突然的压力变化引起的励磁力, 斜盘的倾斜力矩变化大,能够减少振动和噪音的产生。
