Latest Patents

One of Yokoi's latest patents is for a vehicle air conditioner with a mode switching pattern. This invention features an actuator that drives an air mixing door and various mode switching doors. It includes both an automatic range and a manual range, allowing for different operating angle ranges of the actuator. In the automatic range, the air outlet mode is switched automatically based on the opening degree of the air mixing door. Conversely, in the manual range, users can set a multi-mode or defroster mode regardless of the air mixing door's position. This design ensures that air is blown from all openings in multi-mode and specifically from the defroster opening in defroster mode.

Another significant patent by Yokoi is for an air conditioning apparatus for vehicles with a double layer flow mode. This system is activated during maximum heating when both the foot opening and defroster opening are utilized. The air passage is divided into two separate paths: one for inside air and another for outside air. This configuration improves the heating capacity for the vehicle's passenger compartment while reducing the blower's maximum rotation speed.
