  • Patent number: 5810660
    Abstract: An air conditioner includes an air inlet, an air outlet, and a heat exchanger disposed therebetween. Adjustable blades extend across the outlet for controlling the direction of travel of air through the outlet. A door is movable for opening and closing the outlet. A timer counts a time interval following the input of an operation start signal or an operation stop signal and prevents the air conditioner from being started or stopped until a predetermined interval has elapsed. Following the elapse of the time interval, and before the opening or closing of the door, the blades are moved to an out-of-the-way position to avoid obstructing the movement of the door.

  • Patent number: 5765592
    Abstract: A valve body having a circular throat and three vanes mounted for rotation within the circular throat of the valve body. The three vanes comprise two outlying vanes, each having two opposed circular peripheral edges configured so that one of the two opposed circular peripheral edges fits against a circular throat when the vanes are in the closed position. A central vane, preferably of hour glass configuration, is located between the two outlying vanes so that all three vanes nest within the circular throat and against one another when the valve is a closed position. Each of the vanes has a symmetrical axis of rotation and is mounted within the circular throat of the valve body so as to rotate about the symmetrical axis.

  • Patent number: 5658197
    Abstract: An air conditioner includes a housing and a flow control blade mounted in an air discharge outlet of the housing. The blade is rotatable to various positions of adjustment about an axis defined by hinge pins of the blade mounted in hinge holes of the housing. A plurality of the hinge pins extend in the same direction and are of progressively different lengths so that when the blade is installed in the housing, the hinge pins can be successively inserted into their respective hinge holes; the need to simultaneously align all hinge pins with their hinge holes is avoided. A hinge pin disposed at one end of the blade extends in a direction opposite the other hinge pins and is inserted into an open end of a slot formed in the housing.

  • Patent number: 5626517
    Abstract: A flow of air from an air discharge passage has its direction of flow controlled by a series of louvers arranged to swing horizontally back and forth. Each louver has a hinge pin rotatably supported to form an axis of rotation. A connecting member interconnects a plurality of the hinge pins to transmit rotational movement between those hinge pins. The connecting member is attached to each hinge pin by a flexible connection enabling the hinge pin to rotate relative to the connecting member. The connecting member is disposed within a member which shields the connecting member from the air flow.

  • Patent number: 5443420
    Abstract: The direction of air flow in an air blower is controlled by a plurality of rotationally adjustable blades (vanes) extending across an air flow passage. A motor is connected to the blades for rotating the blades between passage-opening and passage-closing positions and intermediate positions therebetween. A sensor senses the angular position of the blades and supplies a signal to a controller which compares that signal to a signal representative of a selected angular position of the blades. If the blades become-displaced by a force independent of the motor, the sensor signals the controller of such displacement, whereupon the motor is actuated to return the blades to the selected position.

  • Patent number: 5385031
    Abstract: A rotational speed of a fan is maintained at a preset one when an angle of a flap is at a maximum air-flow angle, increased by a specified value when the angle of the flap has been changed by a specified angle in the direction away from the position of the maximum air-flow angle, and decreased by a specified value when the angle of the flap has been changed by a specified angle in the direction toward the position of the maximum air-flow angle. It is possible to prevent any occurrence of condensation and air-flow pulsating noise without needing any complex control such as load response control and yet without requiring any complicate construction in the flap.
