  • Patent number: 10899197
    Abstract: An air conditioner includes an inside condenser, an outside heat exchanger, an inside evaporator, a refrigerant circuit switcher, and an air passage switcher. The refrigerant circuit switcher is configured to switch a layout of the refrigerant circuit to (i) a first circuit during a heating mode such that the refrigerant releases heat at the inside condenser and is decompressed to evaporate at the outside heat exchanger and (ii) a second circuit during a defrosting mode such that the refrigerant releases heat at the outside heat exchanger and is decompressed to evaporate at the inside evaporator. The air passage switcher is configured to switch the air passage to (i) a first passage during the heating mode such that the air passes through the inside evaporator and the inside condenser and (ii) a second passage during the defrosting mode such that the air bypasses the inside condenser.

  • Publication number: 20210003142
    Abstract: A propeller fan according to an embodiment of the present invention includes a shaft provided a rotation axis of the propeller fan, and a blade provided on an outer peripheral side of the shaft. The blade has a trailing edge on a rear side of the blade in a rotation direction of the propeller fan. The trailing edge includes a first trailing edge located on an innermost side of the trailing edge, and a second trailing edge adjacent to and outward of the first trailing edge. Where an innermost point of the first trailing edge is a first connection point, a connection point between the first trailing edge and the second trailing edge is a second connection point, and a straight line that extends through the rotation axis and the first connection point is a reference line, the second connection point is located forward of the reference line in the rotation direction, or located on the reference line, and the second trailing edge is located rearward of the second connection point in the rotation direction.

  • Patent number: 10875227
    Abstract: A transparent resin molded product and a mold for molding the product are provided in which occurrence of silver streak in the resin molded product is prevented. The resin molded product includes a design portion and a non-design portion, at least a part of the design portion is molded by transparent resin, and a gate trace (a gate arrangement position during the resin molding) is disposed in the non-design portion (runner portion). A foreign matter restraining portion for restraining foreign matters and bubbles contained in the transparent resin is disposed in the vicinity of the gate trace of the non-design portion. The foreign matters and bubbles are restrained by the foreign matter restraining portion and are prevented from flowing to the design portion, and therefore the occurrence of silver streak on the design portion can be prevented.

  • Patent number: 10583597
    Abstract: A resin-molded component includes a first molding part, and a second molding part. A portion of the first molding part and a portion of the second molding part are laminated in a direction of connecting an outer surface and an inner surface of the resin-molded component to provide a laminated portion. A portion of the second molding part is provided as an exposed portion. Each of portions of the laminated portion is located at least on opposite sides across the exposed portion. A one-side surface of the exposed portion in the laminating direction of the laminated portion is configured as a portion of the outer surface and the other-side surface thereof is configured as a portion of the inner surface.

  • Patent number: 9895859
    Abstract: Provided are a two-color molding method, and a two-color molded article capable of suppressing deterioration of the appearance quality which is caused by resin shrinkage or resin deformation in the two-color molding. The two-color molding method includes: molding a first resin portion by a common die and a primary die; and molding a second resin portion integrally with the first resin portion by the common die and a secondary die. An abutting portion is molded on an edge of the first resin portion to protrude toward the secondary die when the first resin portion is molded, and a distal end surface of the abutting portion is maintained to be abutted on a cavity surface or a parting surface of the secondary die when the second resin portion is molded. The deformation of the abutting portion or the first resin portion is suppressed to suitably mold the second resin portion.
