Definitions

  • the present invention relates, in general, to vent assemblies used for discharging hot and cold air into the passenger compartment of an automobile for accomplishing an air conditioning effect for the passenger compartment and, more particularly, to a vent assembly for automobiles, which has a movable grill unit d esigned to b e a ppropriately e j ected from o r r etracted i nto a h ousing b y a motor operation within a predetermined range capable of preventing an undesired complete removal of the grill unit from the housing, thus allowing a user to selectively eject or retract the grill unit from or into the housing, and which thus allows the user to open the housing when it is desired to clean the grill unit and the interior of the housing, and so the vent assembly blows fresh and clean air into the passenger compartment.
  • air conditioning apparatuses such as heaters or air conditioners, for discharging impure air from the p assenger c ompartment to the atmosphere and feeding fresh hot or cool air into the compartment.
  • air conditioning apparatuses such as heaters or air conditioners
  • Such fresh air fed from such an air conditioning apparatus is blown into the passenger compartment through the grillwork of a vent assembly installed at a dashboard.
  • the grillwork of a conventional vent assembly acting as the final path guiding the fresh hot or cool air into the passenger compartment, comprises a plurality of grating bars which have a blade shape and are movably set in a grill frame fixedly installed in the venting channel of a dashboard. Therefore, when it is desired to change the air blowing direction of the grillwork, the grating bars are manually tilted upward, downward, leftward or rightward at a limited angle within the fixed grill frame.
  • Such deposited dust is blown into the passenger compartment along with fresh hot or cool air during an operation of an air conditioning apparatus, such as a heater or an air conditioner, thus being bad for passengers' health, particularly, for passengers' respiratory organs, and causing several diseases in said organs.
  • an air conditioning apparatus such as a heater or an air conditioner
  • the conventional vent assembly does not allow an installation of an air filter at a position around it, and so most passengers, including a driver while driving an automobile, inevitably breathe dust-laden air blown from the grillwork.
  • This vent nozzle which corresponds to a grill frame with a grillwork and is referred to as "grill frame" herein below, is removably installed in a housing fixedly set in the dashboard of an automobile such that the grill frame with the grillwork is completely removed from the housing by pulling the grill frame from the housing when desired. That is, this grill frame has a detachable structure, which allows a user to install or remove the grill frame with the grillwork in or from the housing provided in the dashboard.
  • this grill frame is not stably installed in the housing, and so it is undesirably moved in the housing to generate noises upsetting passengers around the grill frame when the automobile runs at speed with substantial vibrations.
  • the assembling parts of both the grill frame and the housing may be damaged or broken, thus sometimes forcing the user to change the damaged or broken grill frame and/or housing with new ones.
  • This grill frame is thus inconvenient to the user, and forces the user to pay excessive money for purchasing the new grill frame and/or housing.
  • Another problem of the above grill frame resides in that it may be damaged or lost when it is completely removed from the housing and kept in the removed state for a period of time.
  • an object of the present invention is to provide a vent assembly for automobiles, which has a drawer-type movable grill unit designed to be appropriately ejected from or retracted into a housing in a horizontal direction by a reversible motor operation within a predetermined range defined to prevent an undesired complete removal of the grill unit from the housing, thus allowing a user to selectively eject or retract the grill unit from or into the housing, and which thus allows the user to open the housing when it is desired to clean the grill unit and the interior of the housing, and which thus blows fresh, clean and scented air into the passenger compartment.
  • the present invention provides a vent assembly for automobiles, being installed at a vent channel of a dashboard, and comprising a grill unit and a housing, wherein the grill unit includes a grillwork, and a grillwork holder holding the grillwork therein and integrated with a drawer part, the grill unit being movably set in the housing such that the grill unit is ejected from or retracted into the housing within a predetermined range by a reversible drive means.
