請求項４に記載の発明は、請求項１乃至３の何れかの構成において、モータ室内に、モータを弾性保持する緩衝部材を設けて、弾性体を緩衝部材と一体に設けたことを特徴とするものである。
上記目的を達成するために、請求項５に記載の発明は、モータを収容するモータ室と、ファンを収容するスクロール室と、スクロール室に設けられる吸込口及び排出口と、を有する集塵機であって、モータ室とスクロール室とを繋ぐ連通部を形成し、連通部に弾性変形可能な弾性体を設けたことを特徴とするものである。
上記目的を達成するために、請求項６に記載の発明は、回転軸を有するモータを収容するモータ室と、ファンを収容するスクロール室と、スクロール室に設けられる吸込口及び排出口と、を有する集塵機であって、回転軸を軸支するベアリングを設け、モータ室の内壁とベアリングとの間に、弾性変形可能な弾性体を設けたことを特徴とするものである。
In order to achieve the above object, according to the first aspect of the present invention, the communicating portion between the motor chamber and the scroll chamber is elastically deformed when the internal pressure of the scroll chamber is higher than that of the motor chamber, and the communicating portion is sealed. An elastic body is provided.
The “spindle” here is not only the output shaft of the motor, but also a separate shaft that is coupled integrally with the output shaft, or a separate shaft that is supported in parallel with the output shaft and transmitted from the output shaft. Includes shaft.
According to a second aspect of the present invention, in the configuration of the first aspect, the elastic body is a ring body that is elastically deformed in the radial direction by the internal pressure of the scroll chamber and seals the communicating portion.
According to a third aspect of the present invention, in the configuration of the first or second aspect, a bearing is interposed between the spindle and the elastic body.
According to a fourth aspect of the present invention, in the configuration of any one of the first to third aspects, a buffer member that elastically holds the motor is provided in the motor chamber, and the elastic body is provided integrally with the buffer member. To do.
In order to achieve the above object, an invention according to claim 5 is a dust collector having a motor chamber that houses a motor, a scroll chamber that houses a fan, and a suction port and a discharge port provided in the scroll chamber. Thus, a communication portion that connects the motor chamber and the scroll chamber is formed, and an elastic body that is elastically deformable is provided in the communication portion.
In order to achieve the above object, the invention described in claim 6 includes: a motor chamber that houses a motor having a rotating shaft; a scroll chamber that houses a fan; and a suction port and a discharge port provided in the scroll chamber. The dust collector includes a bearing that pivotally supports a rotating shaft, and an elastic body that can be elastically deformed is provided between the inner wall of the motor chamber and the bearing.
