It is an object of the invention to provide a microparticle diffusing apparatus capable of largely elongating the spray travel distance of microparticles emitted from the microparticle diffusing apparatus and, also, capable of emitting the microparticles in a wide range, enhancing the effect of the microparticles and reducing the noise. The microparticle diffusing apparatus includes a microparticle generating apparatus which generates microparticles from a microparticle generating part, a wind-blowing path which transfers the microparticles generated from the microparticle generating apparatus, and a blowout opening which is formed in an end of the wind-blowing path and which discharges the microparticles, and an aspect ratio of a cross section of the wind-blowing path is gradually increased from a start point to an end point.

It is an object of the invention to provide an ion diffusing apparatus having higher ability by suppressing the disturbance or turbulent flow generated in the vicinity of an ion generating apparatus and by enhancing the ion generating efficiency and the ion transfer efficiency. To achieve this object, the ion diffusing apparatus includes an ion generating apparatus which generates ions from an electrical discharging surface, a wind-blowing path which transmits the ions generated from the ion generating apparatus, and a blowout opening which is formed in an end of the wind-blowing path and which discharges the ions, and the wind-blowing path upstream from the ion generating apparatus is provided with a rectifier which rectifies flow of ions.

Ion diffusing

A cam mechanism has different portions thereof arranged on a main unit, which may be a refrigerator, and on a door. When the door is closed, a hinge pin is locked at one end of a hinge groove, keeping the cam mechanism in a first locked position. As the door is opened, the hinge pin is guided by the hinge groove and a guide pin is guided by a guide groove, permitting the door to rotate and slide. Thus, the hinge pin is locked at the other end of the hinge groove, bringing the cam mechanism to a second locked position. A boss slides on a rib and thereby maintains the second locked position, permitting the door to rotate about the hinge pin. This structure helps realize a door opening/closing mechanism with enhanced operability at reduced cost.

CAM mechanism for shifting a rotary member supported on a base member when the rotary member is opened and closed

A door opening/closing mechanism fitted on a door that closes and opens an opening formed in the body of an apparatus by being brought into and out of contact with the rim of the opening has cam mechanisms that permit the door to engage with and disengage from the body at either of the right and left sides of the door. The cam mechanisms can be brought into a first lock position in which they lie symmetrically at both sides of the door and into a second lock position in which they lie symmetrically at both sides of the door, and each have a hinge pin that serves as a rotation axis in the second lock position and a groove cam that engages with the hinge pin in such a way as to be movable relative to the hinge pin. The groove cam has a slide portion on which a part of the innermost portion of the hinge pin slides when the cam mechanism is moved from the first lock position to the second lock position and of which the length in the direction of the width of the door is greater than the maximum permissible variation in the outermost distance (L) between the two groove cams formed at both sides of the door. When the door is closed, the cam mechanisms at both sides are kept in the first lock position and, when the door is opened at one side, the door slides and thereby causes the cam mechanism at the other side to be brought into the second lock position so as to be rotatably locked in the second lock position.
