Patent JP-H02265139-A (JP)
Title: Overload protection apparatus for motor
Inventor: OKABE TAKIO
IPC: H01H37/54
Filed: 1989-02-17
Abstract: PURPOSE:To make it unnecessary to collect the temperature at a snap operation starting time by installing a fixed contact in the opposite position to a movable contact of a thermostat device which has a movable contact in one end and a supporting plate with a spring property in the other end, installing a spring in the back side of the device, and installing a project which comes in contact with the almost center of the device at the start time of the device. CONSTITUTION:A thermostat device 38 is supported with a supporting plate 39 having a spring property in one end, connected with a movable contact 43 in the other end, and positioned in the opposite to a fixed contact 44. A spring 41 is placed in the opposite side of the movable contact of the thermostat device, and a project 42 is so placed as to come in contact with the thermostat at the start time of the thermostat device 38. Since the contacting part of the supporting plate 39 and the thermostat receives only moderated luminous flux at the level as an open end, outside stress at level to cause stress is not applied to the thermostat device 38 at whole. By this way, the snap operation starting temperature of the thermostat device 38 does not change after assembly of the device, collection and adjustment of the snap operation starting temperature becomes unnecessary.

Title: Protective grille for electric fan
Inventor: WATANABE KENICHI
IPC: F04D25/08
Filed: 1982-03-15
Abstract: PURPOSE:To provide a protective grille for an electric fan, low in its windage loss and suited to reduce the thickness of the fan, by providing an annular rib extending substantially perpendicularly to radial struts constituting the protective grille and arranged to project inward from the struts on the inside of the protective grille. CONSTITUTION:A protective grille 5 is attached to the back of a front casing 1 in the manner of surrounding a propeller fan 3, and an annular rib 8 is fixed to the protective grille 5 at the position thereof located near the front edge portions of the fan 3 in the manner that it is projected toward the propeller fan 3 from the plane of struts 7 of the protective grille 5. Therefore, even if the front edge portions of the fan 3 come into abutment with the grille 5, for instance, due to falling of an electric fan which makes an external force act to reduce the clearance between the propeller fan 3 and the grille 5, the front edge portions of the fan 3 slide on the annular rib 8 while causing deflection of the fan 3, so that the fan 3 can be protected against damages. Thus, since it is not required to increase the size of the struts 7 and the rigidity of the grille 5, it is enabled to obtain a protective grill low in its windage loss and suited to reduce the thickness of the electric fan.
