Abstract

A vehicle air-conditioning apparatus includes a case including an air passage therein and a filter arrangement area provided in the air passage for arranging a filter. The case includes a drain port provided on a bottom portion of a downstream-side air passage in the filter arrangement area; an insertion port provided on a side surface of the case and configured to allow insertion of the filter into the filter arrangement area a water receiving portion provided on a bottom portion of an upstream air passage in the filter arrangement area; a drain channel passing below the filter arrangement area and configured to introduce water from the water receiving portion to the drain port; and a waterproof wall that covers a lower corner portion on the insertion port side of an upstream-side boundary of the filter arrangement areas. The waterproof wall is increased in height toward the insertion port.

First claim

What is claimed is:

1 . A vehicle air-conditioning apparatus comprising:
a case including an air passage in an interior thereof; and a filter arrangement area provided in the air passage for arranging a filter, wherein the case includes:
a drain port provided on a bottom portion of a downstream-side air passage in the filter arrangement area;
an insertion port provided on a side surface of the case and configured to allow insertion of the filter into the filter arrangement area;
a water receiving portion provided on a bottom portion of an upstream air passage in the filter arrangement area;
a drain channel passing below the filter arrangement area and configured to introduce water from the water receiving portion to the drain port; and
a waterproof wall configured to cover a lower corner portion on the insertion port side of an upstream-side boundary of the filter arrangement area, and
the waterproof wall, is increased in height as it goes toward the insertion port.

2 . The vehicle air-conditioning apparatus according to claim 1 , wherein
the drain channel passes through a substantially center portion of the case in a direction of insertion of the filter.

3 . The vehicle air-conditioning apparatus according to claim 1 , wherein
the case further includes a guide wall extending along the direction of insertion of the filter, and the waterproof wall is an upward extending portion of the guide wall.

4 . The vehicle air-conditioning apparatus according to claim 1 , wherein
the case further includes a pair of leg walls extending upright from a bottom surface of the case in parallel to each other along the direction of insertion of the filter at a position downward of the filter arrangement area, and, a floor wall extending between the pair of leg walls for placing the filter.

5 . The vehicle air-conditioning apparatus according to claim 4 , wherein
the drain channel includes an upstream port formed by notching part of the leg wall arranged on the upstream side of the air passage and a downstream port formed by notching part of the leg well arranged on the downstream side of the air passage, and the upstream port is larger than the downstream port.

6 . The vehicle air-conditioning apparatus according to claim 1 , wherein the drain channel and the water receiving portion are formed by depressing a bottom surface of the case.

7 . The vehicle air-conditioning apparatus according to claim 2 , wherein
the case further includes a guide wall extending along the direction of insertion of the filter, and the waterproof wall is an upward extending portion of the guide wall.

8 . The vehicle air-conditioning apparatus according to claim 2 , wherein
the case further includes a pair of leg walls extending upright from a bottom surface of the case in parallel to each other along the direction of insertion of the filter at a position downward of the filter arrangement area, and a floor wall extending between the pair of leg walls for placing the filter.

9 . The vehicle air-conditioning apparatus according to claim 3 , wherein
the case further includes a pair of leg walls extending upright from a bottom surface of the case in parallel to each other along the direction of insertion of the filter at a position downward of the filter arrangement area, and a floor wall extending between the pair of leg walls for placing the filter.

10 . The vehicle air-conditioning apparatus according to claim 8 , wherein
the drain channel includes an upstream port formed by notching part of the leg wall arranged on the upstream side of the air passage and a downstream port formed by notching part of the leg wall arranged on the downstream side of the air passage, and the upstream pert is larger than the downstream port.

11 . The vehicle air-conditioning apparatus according to claim 2 , wherein the drain channel and the water receiving portion are formed by depressing a bottom surface of the case.

12 . The vehicle air-conditioning apparatus according to claim 3 , wherein the drain channel and the water receiving portion are formed by depressing a bottom surface of the case.
