Problems solved by technology

[0008] However, in this prior art, since the pinion and the rack are arranged in the air passage at a position on the air flow upstream side of the above-mentioned opening, and the blown air directly hits the pinion and the rack, foreign matter (sand) that contaminates the blown air , dust, etc.) eventually deposit on the pinion and rack, and get stuck between the pinion and rack
[0009] If foreign matter is caught between the pinion and the rack, there are problems that the rotation of the pinion is blocked, failure occurs, and noise is generated

[0061] Next, a first embodiment of the present invention will be described based on FIGS. 1 to 6 . FIG. 1 shows the overall configuration in the case of applying the present invention to a vehicle air conditioning system, and FIG. 2 is a cross-sectional view of part A-A in FIG. 1 .

[0062] The air conditioning unit 1 of the vehicle air conditioning system in this embodiment has a plastic air conditioning case 1a. The air conditioner case 1a is provided in the interior of the vehicle compartment at an approximate center position in the vehicle width (left-right) direction from the inner side of the instrument panel, and, with respect to the front-rear, top-bottom, and left-right directions of the vehicle as shown in FIG. 1 and 2 are set as shown by the arrows.

[0063] The air conditioner housing 1a is specifically formed to be divided into a plurality of housing members 1b, 1c, and 1d for ease of removal from a mold in the case of molding, and for reasons such as assembling ...

[0161] In the first embodiment, part of the cool air passes through the release hole 39 of the first partition wall 37, and flows to the take-up shaft driving mechanisms 26A and 26B, but, in the second embodiment, as shown in FIGS. 7A and 7B , A film-like blocking member 43 is arranged at the release hole 39 to block passage of cold air through the release hole 39 , and therefore, foreign matter can be better prevented from being deposited at the take-up shaft drive mechanisms 26A and 26B.

[0162] 7A is a schematic cross-sectional view of the main part of the cool air passage opening and closing unit 14a of the membrane door 14 in this embodiment, and FIG. 7B shows a state where the cool air side opening 11a is fully opened in FIG. 7A.

[0163] Note that the hot air passage opening and closing unit 14b is basically the same in configuration as the cold air passage opening and closing unit 14a, so illustration and description are omitted.

[0164] In this embodiment, as the fi...

[0176] In the above-mentioned second embodiment, the film-like blocking member 43 is provided at the discharge hole 39 to block cool air from passing through the discharge hole 39, however, in the third embodiment, as shown in FIGS. Provided at the release hole 39 to block cool air from passing through the release hole 39 .

[0177] 8A is a schematic cross-sectional view of the main part of the cold air passage opening and closing unit 14a of the membrane door 14 in this embodiment, and shows a state where the cold air side opening 11a is completely closed, and FIG. In 8A, the cooling air side opening 11a is fully opened.

[0178] Note that the hot air passage opening and closing unit 14b is basically the same in configuration as the cold air passage opening and closing unit 14a, so illustration and description are omitted.

[0179] The multi-level sliding door 44 in this embodiment uses the basic structure of the multi-level sliding door in Japanese Patent Application No. 20...

Abstract

An air passage opening / closing system preventing extraneous materials from depositing on a windup shaft drive mechanism of a film-shaped member, provided with a case forming air passages through which blown air flows, a film-shaped member arranged in the case and opening and closing openings of the air passages, a fixing part fixing one end of the film-shaped member at a peripheral edge of the openings, a windup shaft connected to the other end of the film-shaped member and winding up and feeding out the film-shaped member, and a windup shaft drive mechanisms rotating the windup shaft and making it move over the openings in a direction away from and approaching the fixing part, the windup shaft and windup shaft drive mechanisms being arranged at an air flow upstream side of the openings, a blown air blocking part covering at least an air flow upstream side part of the windup shaft drive mechanisms being provided.

Description

technical field [0001] The present invention relates to an air passage opening and closing system that opens and closes an air passage through a membrane member (membrane door) and is suitable for use in a vehicle air conditioning system. Background technique [0002] In the past, an air passage opening and closing system using this type of film member to open and close the air passage was proposed in Japanese Patent Publication (A) No. 2005-199988. [0003] In the prior art of this Japanese Patent Publication (A) No. 2005-199988, one end of the membrane member is fixed to the outside of the air passage opening, the other end of the membrane member is connected to the membrane member take-up shaft, Also, the film-like member take-up shaft rotates and moves in a direction away from and close to one end of the film-like member (a side where the film-like member is fixed), whereby the film-like member is rolled up or fed out. ). [0004] Specifically, racks extending from one...
