Description

【発明の詳細な説明】 産業上の利用分野 この発明は、車内の天井等に設置する自動車用空気調和装置に関する。 Detailed description of the invention relates to the present invention relates to an automotive air conditioning system to be installed in a vehicle such as a ceiling.

従来の技術 従来の自動車用空気調和装置は、例えば、第3図のような構造になっていた。 The prior art conventional automotive air conditioner, for example, have a structure such as Figure 3.

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 body 1, the heat exchanger 4 housed in the upper case 2 and lower case 3 and the inner upper and lower cases 2 and 3, the cross-flow fan 5, was composed from the fan motor 6.

発明が解決しようとする課題 しかし第3図に示されるような下ケース3の構造ではファン5駆動時に発生するファンモータ6のモータ音や、 Invention motor noise of the fan motor 6 and which occurs when the fan 5 driven by the structure of the lower case 3 as shown in issue but Figure 3 attempts to solve,
風が熱交換器4を通過する際に発生する風の吸い込み音などの騒音が、上ケース2および下ケース3の内面に反射し、吸込口1aや吹出口1bより本体1外へ漏れるという問題点があった。 Noise of the suction sound of air generated when the wind passes through the heat exchanger 4 is reflected on the inner surface of the upper case 2 and lower case 3, that leaks from the suction port 1a and outlet port 1b to 1 outside body problem there was a point.

特に、本体1は後部座席(図示せず)よりも前部座席14 In particular, the main body 1 is front seats of a rear seat (not shown) 14
に近い場所に配置されるために、前部座席頭部位置14a For placement in close to the front seat head position 14a
近辺に配される吸込口1aから漏れる前部座席14搭乗者に対する騒音が問題となっていた。 Noise to the front seat 14 passengers leaking from the suction port 1a which is disposed in the vicinity has been a problem.

課題を解決するための手段 上記問題点を解決するために本発明は、熱交換器より風上側のケース内底面に、底面から上方へ伸びる防音壁を設けるものである。 The present invention for solving the means above problems in order to solve the problem, on the windward side of the casing bottom than the heat exchanger, is intended to provide a sound barrier extending from the bottom upwards.

作用 この技術的手段による作用は次のようになる。 Action effect of this technical means is as follows. 熱交換器より風上側のケース内底面に、底面から上方へ伸びる防音壁を設けることにより、ケース内で反射した騒音のうち、前部座席頭部位置へ向かう騒音を遮ることができる。 In case the bottom of the windward side of the heat exchanger, by providing a sound barrier extending from the bottom upwards, out of the noise reflected by the case, it is possible to block the noise toward the front seat head position.

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る。 Implementation example will now be described with reference to the accompanying drawings of an embodiment of the present invention.

第1図ないし第2図において、7は上ケース、8は下ケースで、これらにより吸込口13aと吹出口13bを構成している。 In FIG. 1 to FIG. 2, the upper case 7, 8 are composed of the lower case, these by inlet 13a and outlet 13b. 9は熱交換器で前記上下ケース7,8内に斜めに設置されている。 9 is installed obliquely in said upper and lower cases 7,8 in the heat exchanger. 10,11は前記熱交換器9の後に設けられたクロスフローファンとファンモータである。 10 and 11 is a cross-flow fan and fan motor provided after the heat exchanger 9. 13はこれらにより構成された自動車用空気調和装置である。 13 is an automobile air conditioning system constructed in accordance with these.

前記下ケース8において、前記熱交換器9の後方には防音壁12が下ケース8の端面より離れる斜め上方向に向けて設置され、座席頭部位置方向へ伝わる騒音は矢印Aで示すように前記防音壁12によりさえぎられる。 In the lower case 8, the rear of the heat exchanger 9 is installed soundproof wall 12 obliquely upwardly and away from the end face of the lower case 8, the noise transmitted to the seat head position direction as indicated by arrow A intercepted by the sound barrier 12.

発明の効果 本発明によれば、熱交換器より風上側のケース内底面に、底面から上方へ伸びる防音壁を設けることにより、 According to the present invention, on the windward side of the casing bottom than the heat exchanger, by providing a sound barrier extending from the bottom upwards,
ケース内で反射した騒音のうち、前部座席頭部位置へ向かう騒音を遮るため、前部座席搭乗者に対する騒音を低減することができる。 Of the noise reflected by the case, to block out the noise toward the front seat head position, it is possible to reduce noise for the front seat passenger.

また本発明は、ケース内底面に、防音壁を設けるのみであり、特に、部品点数を増やすこともないため、作業工数の増加による作業性の低下を招くこともない。 The present invention, in case the bottom is only providing the sound barrier, particularly for nor increasing the number of parts, nor causing a decrease in workability due to increased working steps.
