  • Patent number: 10969158
    Abstract: A household refrigerator has a receiving space for food, a back panel delimiting the receiving space at the back, a no-frost unit, and an air channel arranged behind the back panel and connected to the no-frost unit and has an outlet opening by which cold air from the no-frost unit can be introduced into the receiving space. A suction opening is provided by way of which air can be sucked out of the receiving space by the no-frost unit. The outlet opening and the suction opening are arranged at different levels. A baffle plate is arranged vertically between the outlet opening and the suction opening. The plate is arranged on the back panel and extends forwards in the direction of a loading opening, so cold air blown into the receiving space via the outlet opening flows around a leading edge of the baffle plate that faces the loading opening.

  • Patent number: 10852044
    Abstract: A device and method are provided to allow replacement of costlier motors with a retrofittable control board and a lower cost motors operating a several speeds to provide variable (but not continuously variable) blower airflow. The control signals normally used to command the motor being replaced are only used to detect the need to activate the blower motor; once detected, the control board activates the replacement blower motor by energizing a blower motor speed tap with the evaporator blower initially set to a high speed. Then the blower speed is lowered if a predetermined negligibly small, acceptable change in evaporator temperature has occurred. Given the number of speed taps on the replacement blower motor, the evaporator blower speed is continued to be reduced from the initially set high speed as long as there is only an acceptably small change in the measured evaporator temperature.
