Abstract
A filter for a vehicle air conditioning apparatus is composed of only a filter medium, and is disposed in a case. A first support member supports a peripheral portion of the filter and a second support member supports a central portion of the filter in the case to prevent deformation of the filter. The filter composed of only the filter medium can be bent, and be detached from the case in a narrow space. It is not necessary to detach opposing parts such as a glove compartment to detach the filter.
Claims35
An air conditioning apparatus comprising:
- a case defining an air passage in which air flows;
- a blower disposed in the air passage for blowing the air;
- and
- a filter disposed to cross the air passage for purifying the air, the filter having a corrugated shape and capable of being bent, wherein:
- the case has an opening portion for detaching the filter therefrom, and includes a first support member for supporting peripheral portion of the filter and a second support member for supporting a central portion of the filter therein;
- the case further includes a blower case portion in which the blower is accommodated, the blower case portion has a suction port from which air is introduced to be blown by the blower;
- the first and second support members are provided in the case to define a filter attachment space at an air flow upstream side of said first and second support members in which the filter is held to be supported by the first and second support members after the filter is inserted from the opening portion into the case;
- the filter is capable of being bent almost at an entire region in a detachment direction thereof and
- the second support member is disposed to be opposite to a part of a downstream side surface of the filter at least at the center portion after the filter is inserted into the case from the opening portion.
