Abstract

PURPOSE:To reduce noise value in a seat crest position, by a method wherein, in a title device disposed to the ceiling of a car body, a cross flow fan and a heat exchanger are contained in a case having a suction port. CONSTITUTION:A case having a suction port 13a and a discharge port 13b is formed with upper and lower cases 7 and 8, and a cross fan 10 and a heat exchanger 9 are contained therein. A hole 14 is formed in a lattice-shape in the upper case 7 for the upper part of the heat exchanger 9. The hole 14 causes noise, sounding in the direction of a ceiling, to pass the hole 14 to a vehicle ceiling 12 where it is absorbed. This constitution enables reduction of a noise value at a seat crest part.

Description

【発明の詳細な説明】 産業上の利用分野 この発明は、自動車用空気調和装置に関する。[Detailed description of the invention] Industrial applications The present invention relates to an air conditioner for an automobile.

従来の技術 従来の自動車用空気調和装置は、例えば、第４図のよう
な構造になっていた。2. Description of the Related Art A conventional air conditioner for an automobile has a structure as shown in FIG. 4, for example.

すなわち本体１は、上ケース２と下ケース３および、前
記上下ケース２．３内に収納された熱交換器４、クロス
フローファン５、ファンモータ６より構成されていた。That is, the main body 1 was composed of an upper case 2, a lower case 3, a heat exchanger 4, a cross flow fan 5, and a fan motor 6 housed in the upper and lower cases 2.3.

発明が解決しようとする問題点 しかし、第４図に示されるような上ケース２の構造では
、ファン５及び熱交換器４で発生した音が、前記上ケー
ス２の内面に反射して、座席頭部位置方向へ伝わったり
、又Ｌケース２が振動して前記座席頭部位置での騒音値
が高いという問題点を有していた。Problems to be Solved by the Invention However, with the structure of the upper case 2 as shown in FIG. There is a problem in that noise is transmitted in the direction of the head position and the L case 2 vibrates, resulting in a high noise level at the seat head position.

における熱交換器の上方に複数の穴を設けたものである
。Means for Solving the Problems and Technical Means of the Invention for Solving the Problems The technical means of the present invention for solving the problems is to provide a plurality of holes above the heat exchanger in the case.

作　　　用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.

。また、格子状のため、ケースが振動して音を発生する
こともない。さらに通風抵抗が大きくなることもない。By providing a plurality of holes in the case, for example, in a grid pattern, sound in the direction of the ceiling is absorbed by the ceiling material of the vehicle, so that the noise value at the seat head position can be suppressed to a low level. Also, because of the lattice shape, the case does not vibrate and make noise. Furthermore, ventilation resistance does not increase.

実施例 以下、本発明の一実施例を添付図面にもとづいて説明す

穴１４を通過して車両の天井材１２により吸収される。10.11 is a cross flow fan and a fan motor provided after the heat exchanger 9. 13 is a cooling unit constituted by these. Said E case 7
In the E-side portion of the heat exchanger 9, holes 14 are provided in a grid pattern, and sound toward the ceiling passes through the grid holes 14 and is absorbed by the ceiling material 12 of the vehicle.

又、天井材１２が硬質で防音効果が少ない場合、天井材
と格子との間に防音材を貼付けてもよい。Furthermore, if the ceiling material 12 is hard and has little soundproofing effect, a soundproofing material may be pasted between the ceiling material and the grid.
