Abstract
A filter structure of a vehicle air conditioner comprises a filter cartridge provided with a plurality of filter papers within a case and a light source. The light source is provided at a position within the filter papers for radiating light toward one side of the case. The light is blocked when pollutants deposited on the filter papers are enough to cause a contaminated state of the filer to reach a preset state. A display section is provided on the case for transmitting the light, radiated from the light source, to be visually checked on the external side. Therefore, the filter structure allows a driver to check a proper exchange time of the filter visually through a display section in which a display state changes according to a contaminated state of the filter.
Claims17
A filter structure of a vehicle air conditioner comprising:
- a filter cartridge provided with a plurality of filter papers that are formed into a plurality of layers within a case;
- a light source, provided at a position within the filter papers, for radiating light toward one side of the case, the light being blocked at the position when pollutants are deposited on the filter papers enough to cause a contaminated state of the filter to reach a preset state;
- and
- a display section, provided on the case, for transmitting the light radiated from the light source to be checked on an external side with a naked eye, so that the naked eye sees a color in the display section due to an amount of transmitted light.
A vehicle air conditioning filter structure, comprising:
- a filter cartridge housing a plurality of filter paper layers;
- a light emitting member configured to transmit light through said filter paper layers toward an edge of said filter cartridge;
- and
- a display section coupled with said filter cartridge and positioned to align with transmitting light such that a user can determine a contaminated state of the filter paper by visually detecting a color change in the display section due to a change in an amount of transmitting light.
A filter structure of a vehicle air conditioner comprising:
- a filter cartridge provided with a plurality of filter papers that are formed into a plurality of layers within a case;
- a light source, provided at a position within the filter papers, for radiating light toward one side of the case, the light being blocked at the position when pollutants are deposited on the filter papers enough to cause a contaminated state of the filter to reach a preset state;
- and
- a display section, provided on the case, for transmitting the light radiated from the light source to be checked on an external side with a naked eye, wherein the display section comprises a base part made of a transmittable material and a checking part formed with a color which is similar to that of the base part when light is transmitted, but which is contrasted with that of the base part when light is not transmitted.
