Description

二輪車用エアコンおよびこれを搭載したエアコン付き二輪車Two-wheeled vehicle air conditioner and two-wheeled vehicle equipped with the same
　本発明は、二輪車用エアコンおよびこれを搭載した電動自転車、オートバイ等のエアコン付き二輪車に関する。 The present invention relates to a motorcycle air conditioner and a two-wheeled vehicle equipped with an air conditioner such as an electric bicycle or a motorcycle equipped with the same.
　一般にオートバイや自転車等の二輪車は、運転者が自動車のように車体枠により覆われるような形となっていないので、走行中に暑さ寒さ等を感じ快適性に欠ける。このため、二輪車、例えば、オートバイの中には、エアコン及びエアコンからの冷風を吹出すエアダクトを設けたエアコン付き二輪車が提案されている（例えば、特許文献１、特許文献２参照）。 In general, motorcycles such as motorcycles and bicycles are not shaped to be covered by a vehicle body frame like a car, so they feel hot and cold during driving and lack comfort. For this reason, two-wheeled vehicles such as motorcycles have been proposed air-conditioner-equipped motorcycles provided with an air conditioner and an air duct that blows out cool air from the air-conditioner (see, for example, Patent Document 1 and Patent Document 2).
　このエアコン付き二輪車は、エアダクトを搭乗者の空調用ヘルメットあるいは空調用衣服に接続し冷風を流して人体を冷やし、その後、空気を直接外部へ放出するようにしている。 This air-conditioned motorcycle has an air duct connected to a passenger's air-conditioning helmet or air-conditioning clothing to cool the human body by flowing cool air, and then directly releases the air to the outside.
実開平３－３８３０８号公報Japanese Utility Model Publication No. 3-38308 特開平１０－１２９２４８号公報JP-A-10-129248
　しかしながら、従来のエアコン付き二輪車は、長くかつ曲がりくねったダクト、換言すると通風抵抗の大きなダクトを介して搭乗者の空調用ヘルメットあるいは空調用衣服内に冷風を供給する構成となっているため、強力な送風能力をもつエアコンとする必要があり、消費エネルギーが大きなものとなる。 However, a conventional motorcycle with an air conditioner is configured to supply cold air into a passenger's air conditioning helmet or air conditioning clothing through a long and winding duct, in other words, a duct with high ventilation resistance. It is necessary to use an air conditioner with an air blowing capacity, and energy consumption becomes large.
　したがって、従来のエアコン付き二輪車を女性やお年寄りにも使用できる簡易な二輪車、例えばモータを動力源とした電動アシスト自転車や電動バイク等の二輪車に適用した場合、エアコンの動力源となるバッテリの持続時間が短いという問題が発生し、電力消費を低減させることが大きな課題となる。 Therefore, when a conventional two-wheeled vehicle with an air conditioner is applied to a simple two-wheeled vehicle that can be used by women and the elderly, for example, a two-wheeled vehicle such as an electric-assisted bicycle or an electric motorcycle that uses a motor as a power source, the battery that is the power source of the air-conditioner is sustained. The problem of short time occurs, and reducing power consumption is a major issue.
　しかしながら、従来のエアコン付き二輪車は、オートバイ等にエアコンを搭載することが記載されているだけで、エンジンをエアコンの動力源として使用できるため、エアコンを低消費電力で動作させる構成についての記述が全く見られない。 However, since a conventional motorcycle with an air conditioner only describes that an air conditioner is mounted on a motorcycle or the like, and the engine can be used as a power source of the air conditioner, there is no description of a configuration for operating the air conditioner with low power consumption. can not see.
　本発明は、低電力消費で駆動可能な二輪車用エアコン及びこれを搭載して快適性と省エネ性を両立したエアコン付き二輪車を提供する。 The present invention provides a two-wheeled vehicle air conditioner that can be driven with low power consumption, and a two-wheeled vehicle equipped with an air conditioner that has both the comfort and energy saving.
　本発明の二輪車用エアコンは、エアコン筐体内を隔壁により上室と下室の上下二室に分離し、上室にその上流側から下流に向かって蒸発器、蒸発器用送風機、空調空気吹き出し口を配置するとともに、下室にその上流側から下流に向かって凝縮器、凝縮器用送風機、吹き出し開口を配置する。さらに、蒸発器の下部に蒸発器より発生するドレン水を集めるドレンパンを設け、このドレンパンからのドレン水を凝縮器に散水する構成とする。また、エアコン付き二輪車はバッテリとともに二輪車用エアコンを車体フレームに搭載し、バッテリにより二輪車用エアコンを駆動する構成である。 The air conditioner for a motorcycle according to the present invention is divided into an upper chamber and a lower chamber in the upper and lower chambers by a partition, and an evaporator, an evaporator blower, and an air conditioning air outlet are provided in the upper chamber from the upstream side to the downstream side. In addition to the arrangement, a condenser, a condenser fan, and a blow-off opening are arranged in the lower chamber from the upstream side to the downstream side. Further, a drain pan that collects drain water generated from the evaporator is provided at the lower part of the evaporator, and the drain water from the drain pan is sprinkled into the condenser. A two-wheeled vehicle with an air conditioner has a structure in which a two-wheeled vehicle air conditioner is mounted on a body frame together with a battery, and the two-wheeled vehicle air conditioner is driven by the battery.
　これにより、二輪車用エアコンは蒸発器で発生したドレン水により凝縮器の周囲温度を下げて凝縮器の熱交換効率を高めることができ、その効率を高めた分、電力消費を抑制することができる。また、この二輪車用エアコンを搭載したエアコン付き二輪車は、エアコンからの空調空気を得て快適な走行ができるとともに、エアコン駆動のために消費する電力が少なくなるので、エアコン空調による快適性と低電力消費による省エネ性を両立することができる。 As a result, the air conditioner for a motorcycle can increase the heat exchange efficiency of the condenser by lowering the ambient temperature of the condenser with the drain water generated in the evaporator, and can suppress the power consumption by the increased efficiency. . In addition, a motorcycle with an air conditioner equipped with an air conditioner for motorcycles can travel comfortably by obtaining conditioned air from the air conditioner and consumes less power to drive the air conditioner. Energy savings due to consumption can be achieved.

FIG. 1 is an external view of an electrically assisted bicycle that is a two-wheeled vehicle with an air conditioner according to an embodiment of the present invention.
　この電動アシスト自転車１はその車体フレーム２の荷台３に二輪車用エアコン５が取り付けてある。 This electric assist bicycle 1 has a motorcycle air conditioner 5 attached to a loading platform 3 of the body frame 2.
　図２は二輪車用エアコン５の断面図であり、図３は二輪車用エアコン５の分解斜視図である。図に示すように、エアコン筐体である外箱１０の、搭乗者が座るサドル側の面、換言すると二輪車用エアコン５内で生じる空気流の下流側となる面に空調空気吹き出し口６を設け、その反対の上流側面に外気取り込み用の吸い込み口１３が設けてある。 FIG. 2 is a cross-sectional view of the air conditioner 5 for a motorcycle, and FIG. 3 is an exploded perspective view of the air conditioner 5 for a motorcycle. As shown in the figure, an air-conditioning air outlet 6 is provided on the saddle side surface on which the passenger sits, that is, on the downstream side of the air flow generated in the motorcycle air conditioner 5 of the outer box 10 that is an air conditioner casing. A suction port 13 for taking in outside air is provided on the opposite upstream side surface.
　外箱１０の内部は、隔壁１６により上部空間の上室７と下部空間の下室８に分離しており、下室８の下流側には隔壁１７で区切られた機械室９が設けてある。 The interior of the outer box 10 is separated into an upper chamber 7 in the upper space and a lower chamber 8 in the lower space by a partition wall 16, and a machine chamber 9 separated by a partition wall 17 is provided on the downstream side of the lower chamber 8. .
　上室７は上流に蒸発器１１が設けてあり、その下流に蒸発器用送風機１２が設けてある。更に蒸発器用送風機１２の下流には吹き出しダクト１４を介して空調空気吹き出し口６が設けてある。空調空気吹き出し口６はダクト２７を着脱自在に接続固定できるようにしてある。 The upper chamber 7 is provided with an evaporator 11 upstream, and an evaporator fan 12 is provided downstream thereof. Further, an air-conditioned air outlet 6 is provided downstream of the evaporator fan 12 via an outlet duct 14. The air-conditioned air outlet 6 is configured so that the duct 27 can be detachably connected.
　下室８は上流に凝縮器１５、その下流に凝縮器用送風機１８が設けてある。更に凝縮器用送風機１８下流の隔壁１７を隔てた機械室９には、圧縮機１９と二輪車用エアコン５を制御する電装部品を収納した電装箱２０が設けてある。そして、下室８の凝縮器用送風機１８は特に外箱１０の側面から風を吹き出す方向に設置してあり、外箱１０の側面に形成した吹き出し開口３０から風を吹き出す構成としてある。 The lower chamber 8 is provided with a condenser 15 upstream and a condenser fan 18 downstream. Further, in the machine room 9 across the partition wall 17 downstream of the condenser blower 18, there is provided an electrical box 20 containing electrical components for controlling the compressor 19 and the motorcycle air conditioner 5. The condenser blower 18 in the lower chamber 8 is installed particularly in the direction of blowing air from the side surface of the outer box 10, and is configured to blow air from the blowing opening 30 formed on the side surface of the outer box 10.
　また、上室７の蒸発器１１の下部には、蒸発器１１で発生したドレン水を集めるドレンパン２１が配置してある。そしてドレンパン２１の底部には複数の孔２２が設けてあり（図４参照）、ドレンパン２１に集まったドレン水をドレンパン２１の下部に設けてある凝縮器１５に散水する構造としてある。 Further, a drain pan 21 for collecting drain water generated in the evaporator 11 is disposed at the lower part of the evaporator 11 in the upper chamber 7. A plurality of holes 22 are provided in the bottom of the drain pan 21 (see FIG. 4), and the drain water collected in the drain pan 21 is sprinkled into the condenser 15 provided in the lower portion of the drain pan 21.
　さらに、下室８の上流の吸い込み口１３と凝縮器１５との間には蓄冷材３３が交換可能な状態で配置してある。図７は蓄冷材３３の形状の一例を示し、蓄冷材３３の中央部には、自転車の進行方向に向けて貫通穴３３ａが複数設けてある。これにより、通風抵抗を最小化しつつ凝縮器１５の周囲温度を下げて、凝縮器１５の熱交換効率を高め、冷凍サイクルの効率を上げて消費電力を抑制することができる。 Furthermore, the cold storage material 33 is arranged between the suction port 13 upstream of the lower chamber 8 and the condenser 15 in a replaceable state. FIG. 7 shows an example of the shape of the cold storage material 33, and a plurality of through holes 33a are provided in the central portion of the cold storage material 33 in the traveling direction of the bicycle. Thereby, the ambient temperature of the condenser 15 can be lowered while minimizing the ventilation resistance, the heat exchange efficiency of the condenser 15 can be increased, the efficiency of the refrigeration cycle can be increased, and the power consumption can be suppressed.
　なお、蓄冷材３３の厚み、貫通穴３３ａの面積、数量は、周囲温度の下げ幅、及び通風抵抗の増加幅により決定することが望ましい。 In addition, it is desirable that the thickness of the regenerator material 33, the area of the through hole 33a, and the quantity thereof are determined by the decrease range of the ambient temperature and the increase range of the ventilation resistance.
　一方、二輪車用エアコン５を搭載した電動アシスト自転車１はバッテリ４を補助動力源としてペダル踏力にモータからの補助力を合成して作動する構成となっている。二輪車用エアコン５はその空調空気吹き出し口６を自転車の前進方向に向けて載せ、荷台３の下面に配置する取り付け具２３を介してねじ込んだ取り付けネジ２６を二輪車用エアコン５の下室８の床部２４に設けた取り付け孔（図示せず）に締め付けることにより固定してある。また、バッテリ４と電装箱２０は電線で接続してある。 On the other hand, the electrically assisted bicycle 1 equipped with the motorcycle air conditioner 5 is configured to operate by synthesizing the auxiliary force from the motor with the pedal depression force by using the battery 4 as an auxiliary power source. The air conditioner 5 for a motorcycle is mounted with its air-conditioned air outlet 6 directed in the forward direction of the bicycle, and a mounting screw 26 screwed through a fixture 23 arranged on the lower surface of the loading platform 3 is attached to the floor of the lower chamber 8 of the motorcycle air conditioner 5.

　以上の構成によりなる二輪車用エアコンとこれを搭載したエアコン付き二輪車である電動アシスト自転車の一連の動作を冷房時について説明する。 A series of operations of a motorcycle air conditioner having the above-described configuration and a motor-assisted bicycle, which is a two-wheeled vehicle equipped with the air conditioner, will be described during cooling.
　外箱１０の前面に設けた電源スイッチ２８をＯＮにして圧縮機１９の運転を開始すると、圧縮機１９→凝縮器１５→膨張器２９→蒸発器１１→圧縮機１９の冷凍サイクルの運転を開始する。同時に蒸発器用送風機１２と凝縮器用送風機１８も回転を始める。 When the operation of the compressor 19 is started by turning on the power switch 28 provided on the front surface of the outer box 10, the operation of the refrigeration cycle of the compressor 19 → the condenser 15 → the expander 29 → the evaporator 11 → the compressor 19 is started. To do. At the same time, the evaporator blower 12 and the condenser blower 18 also start rotating.
　蒸発器用送風機１２の回転により吸い込み口１３より外気が吸い込まれ、この空気は蒸発器１１で熱交換され吹き出しダクト１４を介して空調空気吹き出し口６より吹き出される。これにより、搭乗者は空調空気吹き出し口６からの空調空気（この場合は冷気）を受け、快適に走行することができる。 The outside air is sucked in from the suction port 13 by the rotation of the evaporator blower 12, and this air is heat-exchanged by the evaporator 11 and blown out from the conditioned air blowing port 6 through the blowing duct 14. Thereby, the passenger receives the conditioned air from the conditioned air outlet 6 (cold air in this case) and can travel comfortably.
　この時、空調空気吹き出し口６は、風を吹き出す方向を決めるダクト２７を着脱自在に接続固定できるようにしてあるので、目的に応じたダクトを準備することにより、搭乗者の身体の希望部位に空調空気を当てたり、空調用衣服や空調用ヘルメットに送風したりすることができ、搭乗者の快適性を向上させることができる。 At this time, the air-conditioning air outlet 6 can be detachably connected and fixed to the duct 27 that determines the direction of blowing the wind. Therefore, by preparing a duct according to the purpose, the conditioned air outlet 6 can be attached to a desired part of the passenger's body. Air-conditioned air can be applied, and air-conditioning clothes and air-conditioning helmets can be blown to improve passenger comfort.
　蒸発器１１での熱交換時にドレン水が発生するが、このドレン水は蒸発器１１の下部に設けたドレンパン２１に回収され、ドレンパン２１に設けた複数の孔２２を通過し、ドレンパン２１の下部にある凝縮器１５に散水される。 Drain water is generated during heat exchange in the evaporator 11, and this drain water is collected in the drain pan 21 provided in the lower part of the evaporator 11, passes through a plurality of holes 22 provided in the drain pan 21, and the lower part of the drain pan 21. Water is sprinkled on the condenser 15 in
　凝縮器１５にドレン水（冷水）が散水されることにより、凝縮器１５の蒸発効率が増し、吸い込み空気の温度（外気温）が下がったのと同じ効果が得られるため、凝縮器１５の熱交換効率が上がり運転に要するエネルギーを削減することが出来る。 Since drain water (cold water) is sprinkled into the condenser 15, the evaporation efficiency of the condenser 15 is increased, and the same effect as when the temperature of the intake air (outside temperature) is lowered is obtained. Exchange efficiency increases and energy required for operation can be reduced.
　なお、凝縮器１５に散水されるものの凝縮器１５でも蒸発仕切れなかったドレン水は、凝縮器１５の下部に設けたドレンパン３１で回収され、ドレンパン３１に設けたドレン口３２より二輪車用エアコン５の外に排水される。 The drain water that is sprinkled into the condenser 15 but not evaporated by the condenser 15 is collected by a drain pan 31 provided in the lower part of the condenser 15, and from the drain port 32 provided in the drain pan 31 of the motorcycle air conditioner 5. Drained outside.
　凝縮器用送風機１８の回転により吸い込み口１３より吸い込まれた空気は、凝縮器１５で熱交換され、吹き出し開口３０より吹き出される。 The air sucked from the suction port 13 by the rotation of the condenser blower 18 is heat-exchanged by the condenser 15 and blown out from the blowing opening 30.
　この時、凝縮器用送風機１８は外箱１０の側面にほぼ平行に配置してあるので、空気は外箱１０の側面にほぼ垂直方向に吹き出される。このため外箱１０の側面より吹き出された風は、図５の矢印Ａに示すように自転車が速度を上げて走行していることによる風（図５矢印Ｂ）に吸引される形で風速が上がる。これにより自転車の走行速度が上がれば凝縮器用送風機１８の回転数を下げても凝縮器１５による冷媒の凝縮に必要な風量を得ることができ、消費電力の削減が可能となる。 At this time, since the condenser blower 18 is disposed substantially parallel to the side surface of the outer box 10, the air is blown out substantially vertically to the side surface of the outer box 10. For this reason, the wind blown from the side surface of the outer box 10 is sucked by the wind (arrow B in FIG. 5) generated by the bicycle traveling at a higher speed as shown by the arrow A in FIG. Go up. As a result, if the traveling speed of the bicycle increases, it is possible to obtain the air volume necessary for condensing the refrigerant by the condenser 15 even if the rotational speed of the condenser blower 18 is lowered, and it is possible to reduce power consumption.
　加えて、凝縮器１５で熱交換した風が走行方向に対して横向きに吹き出すことにより、吹き出された暖かい風が自転車の搭乗者に当たるのを防止することができる。 In addition, it is possible to prevent the warm wind blown from hitting the bicycle occupant by blowing the wind exchanged by the condenser 15 in a direction transverse to the traveling direction.
　また、本実施の形態では吸い込み口１３と凝縮器１５との間に蓄冷材３３を設けているので、凝縮器１５を通過する吸い込み空気の温度を外気温よりも下げることができる。したがって、凝縮器１５の熱交換効率が上がり冷凍サイクルの運転に要するエネルギーを効率よく削減することができる。そして、蓄冷材３３は交換することができるので、適宜交換することによって上記効果を必要な時間だけ発揮させることができる。 Further, in the present embodiment, since the cold storage material 33 is provided between the suction port 13 and the condenser 15, the temperature of the suction air passing through the condenser 15 can be lowered below the outside air temperature. Therefore, the heat exchange efficiency of the condenser 15 is increased, and the energy required for the operation of the refrigeration cycle can be efficiently reduced. And since the cool storage material 33 can be replaced | exchanged, the said effect can be exhibited only for the required time by replacing | exchanging suitably.
