  • Publication number: 20230408061
    Abstract: A larger amount of light generated by a light source is emitted to the interior of an accommodation chamber. A lighting device provided on a side wall of an accommodation chamber of a refrigerator includes a light source that generates light, and a cover including a light incident portion on which the light generated by the light source is incident. The cover includes a light exit portion that includes a protrusion formed at a front surface facing the interior of a storage compartment, and causes light to exit to the interior of the storage compartment, and a light reflection diffusion portion that is formed on the back side of the light exit portion at a back surface facing the light source side, includes a plurality of recesses each having an inner peripheral surface, and directs light toward the protrusion.

  • Patent number: 10544797
    Abstract: A propeller fan includes a boss hub portion and a blade including a front edge portion, a rear edge portion, and an outer edge portion. The outer edge portion has a front outer edge portion, a rear outer edge portion, and a connection portion connecting the front outer edge portion and the rear outer edge portion to each other. In a plan view of the blade along a central axis, a maximum radius R1max of the outer edge portion in a portion corresponding to the front outer edge portion and a maximum radius R2max of the outer edge portion in a portion corresponding to the rear outer edge portion satisfy a condition of R1max>R2max. With such a construction, a propeller fan which generates wind less in pressure fluctuation and is capable of sending comfortable wind and achieving lowering in noise is provided.
