Publication number: 20230204272Abstract: An ice making device includes a restriction mechanism for restricting an ice detection lever from moving to a lower side than a restriction position. The restriction mechanism includes a restriction member, a wire spring attached to the restriction member, an opening part and a protruded part provided in the frame. A restriction part of the restriction member is capable of moving between a first rotation position and a second rotation position. When the restriction member is located at the first rotation position, the protruded part elastically deforms the wire spring and urges the restriction member to the first rotation position and, when the restriction member is located at the second rotation position, the protruded part elastically deforms the wire spring and urges the restriction member to the second rotation position. When the restriction member is located at the second rotation position, the restriction part is disposed at the restriction position.Type: ApplicationFiled: December 26, 2022Publication date: June 29, 2023Inventor: Akio ISHIMIZU

Patent number: 11466917Abstract: In an ice making device, a frame supporting an ice tray and a drive unit has a first wall at a side of an ice detection member. Supported on the first wall is a regulation member rotatable between a first rotation position not to regulate coming down of the ice detection member and a second rotation position to regulate coming down of the ice detection member. By moving the regulation member to the second rotation position, later ice making is stopped even if ice accumulating below is not much. The regulation member includes a regulator in a circular arc form and is supported rotatably around a shaft. The regulation member as a rotary member is less liable to unexpectedly move from either of the first rotation position and the second rotation position, so that movement of the regulation member to a position not intended is suppressed.Type: GrantFiled: December 10, 2020Date of Patent: October 11, 2022Assignee: NIDEC SANKYO CORPORATIONInventor: Akio Ishimizu

Patent number: 11378321Abstract: An ice making machine is provided and includes: an ice tray, having a water storage recessed part; a drive part for reversing the ice tray around an axial line passing the ice tray between a water storage position and an ice separation position; and a frame, supporting the ice tray and the drive part. The ice tray includes a water receiving part protruded to an outer side in a portion which is moved to a lower side when the ice tray starts to turn to a CCW direction directing from the water storage position to the ice separation position. The frame includes a projected portion located on an upper side with respect to the water receiving part. The projected portion includes a water passage port for passing the water at a position overlapping with the water receiving part when being viewed in a Z-direction.Type: GrantFiled: September 25, 2018Date of Patent: July 5, 2022Assignee: NIDEC SANKYO CORPORATIONInventors: Akio Ishimizu, Shunji Saito, Katsuhiko Hayashi

Patent number: 7573167Abstract: A geared motor may include a connector, a motor, a deceleration mechanism, an output shaft and a circuit board. The output shaft may include a rotation transmitted part driven by the deceleration mechanism, an external connection part which is disposed apart from the rotation transmitted to be connected with an external member, and a small diameter part formed between the rotation transmitted part and the external connection part. A part of the circuit board is disposed in a space between the rotation transmitted part and the external connection part, and an insertion opening of the connector is opened in a direction that the rotation transmitted part is disposed with respect to the external connection part.Type: GrantFiled: August 6, 2007Date of Patent: August 11, 2009Assignee: Nidec Sankyo CorporationInventors: Katsuki Miyamoto, Shinichi Yoshikawa, Akio Ishimizu
