た。However, in the structure of the upper case 2 as shown in FIG. 4, the motor sound of the fan motor 6 generated when the fan 5 is driven and the wind when passing through the heat exchanger 4 The generated noise such as the suction noise of the wind is reflected on the inner surface of the case 2 and the suction port 1a
There was a problem that it leaked out of Case 2 from the outlet 1b.
特に、ケース２は後部座席（図示せず）よりも前部座
席15に近い場所に配置されるために、前部座席頭部位置
15a近辺に配される吸込口1aから漏れる前部座席15搭乗
者に対する騒音が問題となっていた。Particularly, since the case 2 is arranged closer to the front seat 15 than the rear seat (not shown), the head position of the front seat is reduced.
There was a problem of noise for passengers in the front seats 15 leaking from the intake port 1a arranged near 15a.
問題点を解決するための手段 上記問題点を解決するために本願発明は、吸音効果の
ある部材からなる車室内天井部ケース上面の少なくとも
前記熱交換器風上側に複数の孔を設けたものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of holes at least on the windward side of the heat exchanger on the upper surface of the vehicle interior ceiling case made of a member having a sound absorbing effect. is there.
作用 この技術的手段による作用は次のようになる。車室内

に吸収される。Action The action of this technical means is as follows. By providing a plurality of holes at least on the windward side of the heat exchanger on the upper surface of the case that is in contact with the ceiling of the vehicle interior, noise can pass outside the case without being reflected on the inner surface of the case in the range where the holes on the upper surface of the case are provided. At the same time, it is absorbed by the ceiling material, which is a sound absorbing material.
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

される。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。In FIGS. 1 to 3, 7 is an upper case and 8 is a lower case, which form a suction port 13a and a blowout port 13b. Reference numeral 9 denotes a heat exchanger, which is obliquely installed in the upper and lower cases 7 and 8. Reference numerals 10 and 11 are a cross flow fan and a fan motor provided after the heat exchanger 9. 13
Is a cooling unit composed of these.
In the upper case 7, holes 14 are provided in a lattice shape in a portion above the heat exchanger 9, and sound in the ceiling direction passes through the lattice holes 14 and is absorbed by the ceiling material 12 of the vehicle. To be done. Also, when the ceiling material 12 is hard and has little soundproofing effect,
A soundproof material may be attached between the ceiling material and the grid.
発明の効果 本発明によれば、車室内天井部と接するケース上面の
少なくとも熱交換器より風上側に複数の孔を設けること

ら漏れていた騒音を抑えることができる。EFFECTS OF THE INVENTION According to the present invention, by providing a plurality of holes at least on the windward side of the heat exchanger on the upper surface of the case that is in contact with the vehicle interior ceiling, noise is generated on the inner surface of the case within the range where the holes on the upper surface of the case are provided. Since it passes through the outside of the case without being reflected and is absorbed by the ceiling material that is a sound absorbing material, it is possible to suppress the noise that is reflected in the front seat head position direction on the inner surface of the case and leaks from the suction port.
また本発明は、ケース上面に複数の孔を設けるのみで
