FIG. 2 is a perspective view showing a schematic configuration of the vehicle roof-mounted air conditioner 1 of FIG. 1 and shows a state where a cover is removed. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is a partially enlarged view of the adhesive portion S in FIG. 3 showing the first embodiment of the present invention.

まず、図１中の２は暖房ユニットであり、図示していない走行用のエンジンの冷却水を熱源とするヒータコア３、およびそのヒータコア３にて加熱された空気の流路を成す温風ダクト４Ａからなり、バス車両の床下に配置されている。そして、温風ダクト４Ａは車両の左右それぞれに配置されて車両の長手方向に延びると共に、この温風ダクト４Ａの長手方向端部にはヒータコア３がそれぞれ配置されている。更に、温風ダクト４Ａには複数個の温風吹出口５Ａが形成されており、そこから車室内の乗員足元に向けて温風が吹き出される。   First, reference numeral 2 in FIG. 1 denotes a heating unit, which includes a heater core 3 that uses cooling water of a traveling engine (not shown) as a heat source, and a hot air duct 4A that forms a flow path of air heated by the heater core 3. It is arranged under the floor of the bus vehicle. The hot air duct 4A is disposed on each of the left and right sides of the vehicle and extends in the longitudinal direction of the vehicle, and the heater core 3 is disposed at the longitudinal end of the warm air duct 4A. Furthermore, a plurality of hot air outlets 5A are formed in the hot air duct 4A, from which hot air is blown out toward the passenger's feet in the passenger compartment.

次に１は、図示しないコンデンサ・膨張弁およびエバポレータ１１などからなる周知の冷房ユニット（車両用屋上装着型空調装置）であり、バス車両の屋根１０上に配置されている。冷房ユニット１を構成する冷凍サイクルは、車両用空調装置に使用される周知のものであり、コンプレッサ６、および図示しないコンデンサ・レシーバ・ドライヤ・膨張弁、エバポレータ１１などの各冷凍機器を冷媒配管によって環状に接続して構成される。   Next, 1 is a known cooling unit (vehicle roof-mounted air conditioner) including a condenser / expansion valve and an evaporator 11 (not shown), which is arranged on the roof 10 of the bus vehicle. The refrigeration cycle constituting the cooling unit 1 is a well-known one used in a vehicle air conditioner, and each refrigerant device such as a compressor 6 and a condenser / receiver / dryer / expansion valve (not shown) and an evaporator 11 are connected by refrigerant piping. It is configured by connecting in a ring.

コンプレッサ６は、バス車両の後部床下に配置され、図示しない走行用エンジンから電磁クラッチを介して駆動される。（図１参照）。コンデンサは、コンプレッサ６にて圧縮された高温高圧の冷媒を凝縮させるものである。レシーバは、コンデンサの冷媒流出側に配置され、コンデンサから流出した冷媒のうち液相冷媒を膨張弁に向けて流出する。   The compressor 6 is disposed under the rear floor of the bus vehicle, and is driven from a traveling engine (not shown) via an electromagnetic clutch. (See FIG. 1). The condenser condenses the high-temperature and high-pressure refrigerant compressed by the compressor 6. A receiver is arrange | positioned at the refrigerant | coolant outflow side of a capacitor | condenser, and flows out a liquid phase refrigerant | coolant toward the expansion valve among the refrigerant | coolants which flowed out from the capacitor | condenser.

また、このレシーバは、液相冷媒と気相冷媒との分離を行うと共に、レシーバ内に所定量の冷媒量を蓄えることにより、冷凍サイクル内を循環する冷媒量を調節するものである。そのレシーバの液相冷媒流出側には、冷媒の減圧装置を成す膨張弁が配設されている。尚、この膨張弁は温度式となっており、エバポレータ１１の冷媒流出側の冷媒温度に応じて、その弁開度を調節している。   The receiver separates the liquid-phase refrigerant and the gas-phase refrigerant and stores a predetermined amount of refrigerant in the receiver to adjust the amount of refrigerant circulating in the refrigeration cycle. An expansion valve constituting a refrigerant decompression device is disposed on the liquid phase refrigerant outflow side of the receiver. This expansion valve is a temperature type, and its opening degree is adjusted according to the refrigerant temperature on the refrigerant outflow side of the evaporator 11.

具体的には、エバポレータ１１の冷媒流出側に冷媒温度を感知する感温筒を配設し、冷媒温度（冷房負荷）が高い時には弁開度を増し、冷媒温度（冷房負荷）が低い時には弁開度を絞るものである。そして、その膨張弁の冷媒流出側には、減圧されて低温低圧となった液相冷媒を蒸発させて空調用空気を冷却するエバポレータ１１が配設されている（図２、図３参照）。   Specifically, a temperature sensing cylinder that senses the refrigerant temperature is arranged on the refrigerant outflow side of the evaporator 11, and the valve opening is increased when the refrigerant temperature (cooling load) is high, and the valve is opened when the refrigerant temperature (cooling load) is low. The opening is reduced. An evaporator 11 that cools the air-conditioning air by evaporating the low-pressure and low-pressure liquid-phase refrigerant is disposed on the refrigerant outflow side of the expansion valve (see FIGS. 2 and 3).

冷房ユニット１は、図２に示すようにコンデンシングユニット部１２とクーリングユニット１３部とを一体に構成したものである。コンデンシングユニット部１２は、図示しないコンデンサと、このコンデンサに外気を送風するファン１４などより構成されている。また、クーリングユニット部１３は、空調ケース（本体ケース）７内に、エバポレータ１１と、このエバポレータ１１に車室内の空気（内気）、もしくは車室外の空気（外気）を通風するためのブロワ１５などより構成されている。   As shown in FIG. 2, the cooling unit 1 includes a condensing unit 12 and a cooling unit 13 integrally formed. The condensing unit section 12 includes a capacitor (not shown) and a fan 14 that blows outside air to the capacitor. The cooling unit 13 includes an evaporator 11 in an air conditioning case (main body case) 7, a blower 15 for passing air inside the vehicle interior (inside air), or air outside the vehicle interior (outside air) to the evaporator 11. It is made up of.

ブロワ１５によってエバポレータ１１に通風された空気は、エバポレータ１１を通過する際に低温冷媒との熱交換により冷却されて車室内の冷風ダクト４Ｂ（図１参照）へ供給される。冷風ダクト４Ｂは、車両の左右それぞれに配置されて車両の長手方向に延びている。更に、冷風ダクト４Ｂには、複数個の冷風吹出口５Ｂが形成されており、そこから車室内の乗員頭部に向けて冷風が吹き出される。   The air ventilated to the evaporator 11 by the blower 15 is cooled by heat exchange with the low-temperature refrigerant when passing through the evaporator 11 and supplied to the cool air duct 4B (see FIG. 1) in the vehicle interior. The cold air duct 4B is disposed on each of the left and right sides of the vehicle and extends in the longitudinal direction of the vehicle. Furthermore, a plurality of cold air outlets 5B are formed in the cold air duct 4B, from which cold air is blown toward the passenger's head in the passenger compartment.

尚、図示しない空調制御装置へは、例えば運転手などの乗員が空調装置の運転・停止、および設定温度や風量などを設定する図示しない空調操作パネルからの操作信号などが入力され、それに応じて上述の冷房ユニット１・暖房ユニット２、およびコンプレッサ６などの各冷凍機器が、この空調制御装置によって制御されている。   Note that an air conditioning control device (not shown) receives, for example, an operation signal from an air conditioning operation panel (not shown) in which an occupant such as a driver sets the operating / stopping of the air conditioning device and sets a set temperature, an air volume, and the like. Refrigerating equipment such as the cooling unit 1 and the heating unit 2 and the compressor 6 described above is controlled by this air conditioning control device.

次に、図３を用いて、クーリングユニット部１３の具体的な構成・構造について説明する。クーリングユニット部１３が配置されるバス車両の天井には、矩形状に形成された内気吸込口１６が開口しており、車室内とクーリングユニット部１３の内部とを連通させている。そして、内気モードとしてブロワ１５が作動した場合には、内気吸込口１６を通して車室内の空気がクーリングユニット部１３内部へ導入されてエバポレータ１１へ通風される。   Next, a specific configuration / structure of the cooling unit 13 will be described with reference to FIG. An inside air suction port 16 formed in a rectangular shape is opened in the ceiling of the bus vehicle on which the cooling unit portion 13 is disposed, and the vehicle interior communicates with the inside of the cooling unit portion 13. When the blower 15 is operated in the inside air mode, the air in the vehicle compartment is introduced into the cooling unit 13 through the inside air inlet 16 and is ventilated to the evaporator 11.

また、クーリングユニット部１３の車両中央側の側面には、車室外の空気を導入する外気導入経路９として、外気ダクト９ａと９ｂとが設けられている。この外気ダクト９ａ・９ｂは、空調ケース７の外側へ突出させて設けられていると同時に、空調ケース７の内側へも延長して設けられている。また、これら、外気ダクト９ａ・９ｂは、空調ケース７の外側下方へ傾斜させて設けられている。   Further, outside air ducts 9a and 9b are provided on the side surface of the cooling unit portion 13 on the vehicle center side as outside air introduction paths 9 for introducing air outside the passenger compartment. The outside air ducts 9 a and 9 b are provided so as to protrude to the outside of the air conditioning case 7 and are also provided to extend to the inside of the air conditioning case 7. Further, these outside air ducts 9 a and 9 b are provided to be inclined outward and downward of the air conditioning case 7.

そして、空調ケース７の内側である外気ダクト９ｂの内側部分には、外気に乗って入ってくる雨水や塵埃が空調ケース７の内部へ侵入するのを防止する外気フィルタ（第１の除塵フィルタ）１８が配設されている。この外気フィルタ１８は、空調ケース７の内側から外気ダクト９ｂの端面部分にセットされ、押え枠であるフィルタブラケット２１を上からセットして、螺子２２を締め込むことによって固定されている。   Then, an outside air filter (first dust filter) that prevents rainwater and dust that enters the outside air from entering the inside of the air conditioning case 7 enters the inside portion of the outside air duct 9b that is inside the air conditioning case 7. 18 is arranged. The outside air filter 18 is set on the end face portion of the outside air duct 9b from the inside of the air conditioning case 7, and is fixed by setting a filter bracket 21 as a holding frame from above and tightening a screw 22.

また、この外気フィルタ１８と先の内気吸込口１６との間には、内外気切換部としての仕切り板部材１９によって換気空間が形成されており、仕切り板部材１９に開口された外気流入口１９ａと内気吸込口１６とを、内外気切替手段である内外気切替ドア１７にて切替開閉することで外気モードと内気モードとを切り替えるようになっている。   Further, a ventilation space is formed between the outside air filter 18 and the previous inside air suction port 16 by a partition plate member 19 as an inside / outside air switching portion, and an outside air flow inlet 19 a opened to the partition plate member 19. Are switched between the outside air mode and the inside air mode by switching between the inside and outside air switching door 17 which is inside / outside air switching means.

ちなみに図３は、内外気切替ドア１７にて外気流入口１９ａを閉じて外気の流入を封止しているとともに、内気が流入するように内気吸込口１６を開放した内気モードの状態を示している。内外気切替ドア１７には、外気流入口１９ａや内気吸込口１６を閉じたときの密閉性を確保するため、シール部材２３が両面に設けられている。   Incidentally, FIG. 3 shows a state of the inside air mode in which the outside air inlet 19a is closed by the inside / outside air switching door 17 to seal the inflow of outside air, and the inside air inlet 16 is opened so that the inside air flows. Yes. The inside / outside air switching door 17 is provided with sealing members 23 on both sides in order to ensure hermeticity when the outside air inlet 19a and the inside air inlet 16 are closed.

また、内外気切換部の空気流れ下流側に配置されたエバポレータ１１の通風前面側には、空気清浄手段としての内外気フィルタ２５が配置されている。この内外気フィルタ２５は、細かい塵埃を取り除く第２の除塵フィルタ部と、もう一つの空気清浄手段としての脱臭フィルタ部とを合わせた複合フィルタなどである。   Further, an inside / outside air filter 25 as an air cleaning means is arranged on the ventilation front side of the evaporator 11 arranged on the downstream side of the air flow of the inside / outside air switching unit. The inside / outside air filter 25 is a composite filter or the like in which a second dust removing filter portion that removes fine dust and a deodorizing filter portion as another air cleaning means are combined.

除塵フィルタ部は、ひだ折りした不織布などから成り、空気中の塵や液状粒子（例えば、ニコチンやタール）などを捕捉して除去するものである。また、脱臭フィルタ部は、ハニカム担体に添着された活性炭より成り、空気中の臭いを除去するものである。いずれも薄く長尺状をしたフィルタ部材を貼り合わせるなどして内外気フィルタ２５を形成している。   The dust removal filter unit is made of a folded nonwoven fabric, and traps and removes dust and liquid particles (for example, nicotine and tar) in the air. The deodorizing filter portion is made of activated carbon attached to the honeycomb carrier and removes odors in the air. In both cases, the inside / outside air filter 25 is formed by bonding thin and long filter members.

また、このような構成を持った空調ケース７の上面開口部は、空調ケース蓋部材としての空調ケースカバー８で覆って各部との密閉を保つようになっており、空調ケースカバー８を開けることにより上面開口部から内部の機器のメンテナンス作業を行うようになっている。   Further, the upper surface opening of the air conditioning case 7 having such a structure is covered with an air conditioning case cover 8 as an air conditioning case lid member so as to keep hermetic seal with each part, and the air conditioning case cover 8 is opened. Thus, the maintenance work of the internal equipment is performed from the upper surface opening.

次に、本発明に関する要部の構成・構造について、図４を用いて説明する。本空調装置は、バスの平坦な屋根１０上に接着固定される構造となっている。本体ケース７は、ＡＢＳ（アクロル二トリル・ブタジエン・スチレン）樹脂を真空成形したものであり、この本体ケース７の下ケース７１の外周部全周に、屋根１０と接着するための接着部Ｓが形成されており、その接着部Ｓ内に接着材Ｂの厚さを所定厚さに保つための凸部７１ａを複数箇所設けている。   Next, the configuration and structure of the main part relating to the present invention will be described with reference to FIG. This air conditioner has a structure that is bonded and fixed onto a flat roof 10 of a bus. The main body case 7 is formed by vacuum-forming ABS (acrylonitrile, butadiene, styrene) resin, and an adhesive portion S for adhering to the roof 10 is provided on the entire outer periphery of the lower case 71 of the main body case 7. A plurality of convex portions 71 a are formed in the adhesive portion S to keep the thickness of the adhesive material B at a predetermined thickness.

より具体的には、下ケース７１と屋根１０との隙間を５ｍｍ程度に保つための凸部７１ａを、図示しないが車両前後方向に左右２箇所ずつ、車両左右方向に前後１箇所ずつ、計６箇所で下ケース７１に一体にして形成している。なお、凸部７１ａは点であっても良いし、ビート状（線状）であっても良い。また、使用する接着剤はポリウレタン系の接着剤などて、エアーガンなどでビート状に塗布するようなものである。   More specifically, although not shown, convex portions 71a for keeping the gap between the lower case 71 and the roof 10 at about 5 mm are provided in two places on the left and right sides in the vehicle longitudinal direction and one place on the left and right sides in the vehicle left and right direction, for a total of 6 It is formed integrally with the lower case 71 at some points.

空調装置を屋根上に接着する作業の概要としては、１．屋根の接着する部分の面荒らしを行い、２．その部分を洗浄し、３．下地として接着を向上させるためのプライマーを塗布し、４．接着剤を塗布し、５．空調装置を載置する手順となる。ちなみに従来は、プライマーや接着剤を塗布する前に、屋根上にスペーサを貼り付け固定するという作業が入っていることとなる。なお、図４中の７２は、内側カバーの一部である。   The outline of the work of bonding the air conditioner on the roof is as follows. 1. Roughen the part of the roof that adheres. 2. wash that part; 3. Apply a primer for improving adhesion as a base; 4. Apply adhesive. The procedure is to place the air conditioner. Incidentally, conventionally, before applying a primer or an adhesive, an operation of attaching and fixing a spacer on the roof is included. Note that reference numeral 72 in FIG. 4 denotes a part of the inner cover.

次に、本実施形態での特徴と、その効果について述べる。まず、屋根１０と空調装置の本体ケース７との接着部Ｓ内に、接着材Ｂの厚さを所定厚さに保つための凸部７１ａを複数箇所設けている。これによれば、従来のスペーサに代わる凸部７１ａを屋根１０と本体ケース７との接着部Ｓ内に形成することで、従来別部品としていたスペーサが不要となるうえ、そのスペーサを複数、屋根の接着面に貼り付け固定するという作業が不要となることより、空調装置の装着コストを抑えることができる。   Next, features and effects of this embodiment will be described. First, a plurality of convex portions 71a for keeping the thickness of the adhesive B at a predetermined thickness are provided in the adhesive portion S between the roof 10 and the main body case 7 of the air conditioner. According to this, by forming the convex portion 71a in place of the conventional spacer in the bonding portion S between the roof 10 and the main body case 7, the spacer which has been conventionally used as a separate part becomes unnecessary, and a plurality of the spacers are provided on the roof. Since the work of attaching and fixing to the adhesive surface of the air conditioner becomes unnecessary, the installation cost of the air conditioner can be suppressed.

また、凸部７１ａを本体ケース７に一体に形成している。これは、本体ケース７が樹脂成形品であるところに着目したものであり、これによれば、本体ケース７に凸部７１ａを一体に形成してしまうことで空調装置のコストを抑えることができる。   Further, the convex portion 71 a is formed integrally with the main body case 7. This is focused on the fact that the main body case 7 is a resin molded product, and according to this, the cost of the air conditioner can be reduced by forming the convex portion 71a integrally with the main body case 7. .
