Abstract
Description
本発明は、車室内に所定温度の空調風を供給する車両用空調装置に関する。 The present invention relates to a vehicle air conditioner that supplies conditioned air at a predetermined temperature into a passenger compartment.
特許文献1に「後部座席用空調装置」が記載されている。この従来の空調装置にあっては、送風用ブロア（送風機）の吸込口の略中央に、通過する空気の温度を検出する温度センサが配設されており、車体パネルの内側に位置するトリム（内装パネル）に形成された開口部からブロアの吸込口に流れる空気の主流を前記の温度センサで検出し、この温度センサから出力される検出信号に基づいて送風路から車室内の後部座席に向けて吹出す空気の温度を調節するようになっている。
しかしながら、特許文献１に記載されている従来技術では、トリムの開口部とブロアの吸込口とを結ぶ吸込ダクトがない場合、ブロアの吸込口を介してブロアに空気を吸込む際に、車体パネル及びトリム間に形成されるパネル内部空間の空気も含まれており、このパネル内部空間は車体パネルと外気の温度により熱くなったり寒くなったり温度変動が激しいため、ブロアの吸込口の略中央に配置された温度センサで検出した空気温度のばらつきが生じ、温度測定の精度が劣るという問題がある。また、上述した空気温度のばらつきに伴ってブロアの吸込口では温度分布が生じて場所により温度差があるため、温度センサをブロアの吸込口の略中央に配置しても、この温度センサの取付位置等により正確な温度測定が難しいという問題がある。また、ブロアの吸込側では負圧となり風速が小さいことから、ブロアのファンが低速で回転する際に温度センサ（抵抗体）自身の発熱により実際の空気温度より高めの温度を検出し、温度測定の誤差が生じるという問題もある。 However, in the prior art described in Patent Document 1, when there is no suction duct connecting the opening of the trim and the suction port of the blower, when the air is sucked into the blower through the suction port of the blower, Also included is the air inside the panel formed between the trims, and this panel internal space becomes hot or cold depending on the temperature of the vehicle body panel and outside air, and the temperature fluctuates severely, so it is placed at the approximate center of the blower inlet. There is a problem that the temperature of the air detected by the temperature sensor varies and the accuracy of temperature measurement is poor. In addition, the temperature distribution at the blower inlet due to the above-mentioned variation in air temperature and there is a temperature difference depending on the location, so even if the temperature sensor is placed at the approximate center of the blower inlet, There is a problem that accurate temperature measurement is difficult depending on the position and the like. Also, since the blower suction side has negative pressure and the wind speed is low, when the blower fan rotates at a low speed, the temperature sensor (resistor) itself detects the temperature higher than the actual air temperature and measures the temperature. There is also a problem that this error occurs.
本発明は、上記のような従来技術を考慮してなされたもので、その目的は、車室内へ供給する空調風の温度測定精度を向上できると共に、風量の少ない状態でもきめ細かい温度制御を行なうことのできる車両用空調装置を提供することにある。 The present invention has been made in consideration of the above-described prior art, and an object of the present invention is to improve the temperature measurement accuracy of the conditioned air supplied to the passenger compartment and to perform fine temperature control even in a state where the air volume is small. An object of the present invention is to provide a vehicle air conditioner capable of performing the above.
上記目的を達成するため請求項１記載の発明は、電動モータにより駆動される送風用ブロアと、このブロアに接続される送風路と、この送風路を通る空気の熱交換を行なう熱交換器と、前記送風路から車室内へ空気を吹出す複数箇所の吹出し口とを備えた車両用空調装置であって、前記ブロアに設けられるファンの下流側に、通過する空気の温度を検出する温度検出手段を配置し、この温度検出手段から出力される検出信号に基づいて前記送風路を通過する空気の温度を調節する構成にしてある。 In order to achieve the above object, a first aspect of the present invention is directed to a blower blower driven by an electric motor, a blower passage connected to the blower, and a heat exchanger for exchanging heat of air passing through the blower passage. A vehicle air conditioner comprising a plurality of air outlets for blowing air from the air passage into the vehicle compartment, and detecting the temperature of air passing downstream of a fan provided in the blower Means are arranged, and the temperature of the air passing through the air passage is adjusted based on the detection signal output from the temperature detection means.
このように構成した請求項１記載の発明では、ブロアの作動時にファンにより吸込口を介して空気を吸入して攪拌することにより、空気温度のばらつきがなくなり温度が均一となった状態で送風し、上記のファンの下流側に配置した温度検出手段で通過する空気の温度を検出する。このとき、ブロアの吐出側では風速が比較的大きいため、温度検出手段自身の発熱による空気温度への影響が少なくなる。次いで、温度検出手段からの検出信号に基づいて送風路を通過する空気の温度を調節する。これによって、吸込んだ空気の平均温度をファンの下流側で測定できるので、車室内へ供給する空調風の温度測定精度を向上できる。また、ファンが低速で回転する場合であっても、温度検出手段自身の発熱に伴う温度測定の誤差を抑制できるので、風量の少ない状態でもきめ細かい温度制御を行なうことができる。 In the invention according to claim 1 configured as described above, when the blower is operated, the air is sucked and stirred by the fan through the suction port so that the air is not dispersed and the air is blown in a state where the temperature is uniform. The temperature of the air passing therethrough is detected by temperature detection means arranged on the downstream side of the fan. At this time, since the wind speed is relatively high on the discharge side of the blower, the influence of the heat generated by the temperature detection unit itself on the air temperature is reduced. Next, the temperature of the air passing through the air passage is adjusted based on the detection signal from the temperature detection means. Thereby, since the average temperature of the sucked air can be measured on the downstream side of the fan, the temperature measurement accuracy of the conditioned air supplied to the vehicle interior can be improved. Further, even when the fan rotates at a low speed, temperature measurement errors due to the heat generation of the temperature detecting means itself can be suppressed, so fine temperature control can be performed even in a state where the air volume is small.
本発明では、車室内へ供給する空調風の温度測定精度を向上できると共に、風量の少ない状態でもきめ細かい温度制御を行なうことができ、したがって、より正確で、かつ所望の自動空調制御が可能な車両用空調装置を提供できるという効果がある。 In the present invention, the temperature measurement accuracy of the conditioned air supplied to the passenger compartment can be improved, and fine temperature control can be performed even in a state where the air volume is small. Therefore, a vehicle capable of more accurate and desired automatic air conditioning control. There is an effect that an air conditioner can be provided.
以下、本発明の実施の形態に係る車両用空調装置の詳細を図に基づいて説明する。 Hereinafter, details of a vehicle air conditioner according to an embodiment of the present invention will be described with reference to the drawings.
図１は本発明の一実施形態に係る車両用空調装置の全体構成を示す説明図、図２は本実施形態に設けられる温度検出手段の取付部分をブロアの吸込側から見た斜視図、図３は本実施形態に設けられる温度検出手段の取付部分をブロアの吐出側から見た斜視図である。なお、図３ではブロアの吐出側を覆う吐出側ケーシングを取除いた状態で示しているため、図３の左側に取付ブラケットが浮いて見えている。 FIG. 1 is an explanatory view showing the overall configuration of a vehicle air conditioner according to an embodiment of the present invention, and FIG. 2 is a perspective view of a mounting portion of a temperature detecting means provided in the present embodiment as viewed from the suction side of a blower. 3 is a perspective view of a mounting portion of the temperature detecting means provided in the present embodiment as viewed from the blower discharge side. In addition, in FIG. 3, since it has shown in the state which removed the discharge side casing which covers the discharge side of a blower, the attachment bracket is floating on the left side of FIG.
図１に示すように本実施形態の車両用空調装置１は、車体パネル２及びこの車体パネル２より内側に位置するトリム３（内装パネル）の間に形成されるパネル内部空間４に設けられている。トリム３は、パネル内部空間４と車室内とを連通する開口部５を有している。なお、この開口部５と後述するブロア７の吸込口６の間には吸込ダクトが設けられていない。 As shown in FIG. 1, the vehicle air conditioner 1 of the present embodiment is provided in a panel internal space 4 formed between a vehicle body panel 2 and a trim 3 (interior panel) located inside the vehicle body panel 2. Yes. The trim 3 has an opening 5 that communicates between the panel internal space 4 and the vehicle interior. A suction duct is not provided between the opening 5 and a suction port 6 of the blower 7 described later.
また、車両用空調装置１は、トリム３側に向く吸込口６を有する送風用ブロア７と、このブロア７に一端が接続される送風路８と、ブロア７の下流側に配置される温度検出手段９及びモータ制御手段１０（ＭＯＳモジュール）と、図示しない外部冷媒回路を循環する冷媒を介して送風路８内の空気の熱交換を行なう熱交換器１１（蒸発器）と、この熱交換器１１の下流側に配設され、エンジン（図示せず）の冷却水を熱源とするヒータコア１２と、このヒータコア１２を通過する風量とバイパスする風量との割合を調節するエアミックスドア１３と、送風路８から車室内へ空気を吹出す図示しない複数箇所の吹出し口を切換えるモードドア１４とを備えている。 The vehicle air conditioner 1 also includes a blower blower 7 having a suction port 6 facing the trim 3 side, a blower path 8 having one end connected to the blower 7, and a temperature detection disposed on the downstream side of the blower 7. Means 9 and motor control means 10 (MOS module), a heat exchanger 11 (evaporator) for exchanging heat of the air in the air passage 8 via a refrigerant circulating in an external refrigerant circuit (not shown), and this heat exchanger 11, a heater core 12 that uses cooling water of an engine (not shown) as a heat source, an air mix door 13 that adjusts the ratio of the air volume that passes through the heater core 12 and the air volume that bypasses, A mode door 14 for switching a plurality of outlets (not shown) for blowing air from the road 8 into the vehicle compartment is provided.
図２及び図３に示すようにブロア７は、吸込側の回転軸方向から吸入した空気を径方向に吹出す遠心式ファン１５と、このファン１５を駆動する電動モータ１６と、渦巻き状に形成され、ファン１５及び電動モータ１６を収容するケーシング１７とから構成されており、このケーシング１７はパネル内部空間４に配置され、取付ブラケット１８などを介して支持されている。 As shown in FIGS. 2 and 3, the blower 7 is formed in a spiral shape, a centrifugal fan 15 that blows out the air sucked in from the direction of the rotation axis on the suction side, an electric motor 16 that drives the fan 15, and the like. The casing 17 is configured to house the fan 15 and the electric motor 16. The casing 17 is disposed in the panel internal space 4 and is supported via a mounting bracket 18 and the like.
温度検出手段９は、ファン１５の下流側でかつ熱交換器１１の上流側に配置され、ケーシング１７の吸込側に装着されるインカーセンサ基部１９と、このインカーセンサ基部１９よりケーシング１７内に突出し、ファン１５より吐出される空気の温度を検知するインカーセンサ素子２０とから構成されている。 The temperature detection means 9 is arranged on the downstream side of the fan 15 and the upstream side of the heat exchanger 11, and the inker sensor base portion 19 mounted on the suction side of the casing 17, and protrudes into the casing 17 from the inker sensor base portion 19. The inker sensor element 20 detects the temperature of the air discharged from the fan 15.
この実施形態にあっては、ブロア7の作動時にファン１５により吸込口６を介して空気を図２の矢印で示す方向に吸入する。このとき、トリム３の開口部５とブロア７の吸込口６の間には吸込ダクトが設けられていないため、開口部５を介して車室内の空気が吸込まれると共にパネル内部空間４の空気も吸込まれるので、これらの空気が混じり合って温度変動が大きい状態にある。次いで、ブロア７のファン１５で空気を攪拌することにより空気温度のばらつきがなくなり温度が均一になった状態で、図３の矢印で示す方向に送風した後、ファン１５の下流側に配置したインカーセンサ素子２０により通過する空気の温度を検出し検出信号を出力する。このとき、ブロア７の吐出側では風速が比較的大きいためインカーセンサ素子２０自身の発熱による空気温度への影響が少なくなる。次いで、上記の検出信号に基づいて送風路８から車室内へ吹出す空気の温度を調節するようになっている。 In this embodiment, when the blower 7 is operated, the fan 15 sucks air through the suction port 6 in the direction indicated by the arrow in FIG. At this time, since no suction duct is provided between the opening 5 of the trim 3 and the suction port 6 of the blower 7, air in the vehicle compartment is sucked through the opening 5 and air in the panel internal space 4. Since the air is also sucked in, the air is mixed and the temperature fluctuation is large. Next, after the air is agitated by the fan 15 of the blower 7 and the air temperature does not vary and becomes uniform, the air is blown in the direction indicated by the arrow in FIG. The car sensor element 20 detects the temperature of the passing air and outputs a detection signal. At this time, since the wind speed is relatively high on the discharge side of the blower 7, the influence of the heat generated by the inker sensor element 20 itself on the air temperature is reduced. Next, the temperature of the air blown out from the air passage 8 into the passenger compartment is adjusted based on the detection signal.
このように構成した本実施形態では、吸込んだ空気の平均温度をファン１５の下流側で測定できるので、自動温度制御時に車室内へ供給する空調風の温度設定をより正確に行なえると共に、温度検出手段９の取付位置を幅広く設定でき、温度検出手段９の取付位置の自由度が高くレイアウトが容易である。 In the present embodiment configured as described above, since the average temperature of the sucked air can be measured on the downstream side of the fan 15, the temperature of the conditioned air supplied to the passenger compartment during the automatic temperature control can be set more accurately, and the temperature A wide range of attachment positions of the detection means 9 can be set, the degree of freedom of the attachment position of the temperature detection means 9 is high, and the layout is easy.
また、本実施形態では、ファン１５が低速で回転する場合であっても、インカーセンサ素子２０自身の発熱に伴う温度測定の誤差を抑制できるので、風量の少ない状態でもきめ細かい温度制御を行なうことができる。 Further, in the present embodiment, even when the fan 15 rotates at a low speed, temperature measurement errors due to heat generation of the inker sensor element 20 itself can be suppressed, so fine temperature control can be performed even in a state where the air volume is small. it can.
なお、上記実施形態にあっては、ブロア７のケーシング１７内に、ファン１５より吐出される空気の温度を検知するインカーセンサ素子２０を設けたが、本発明はこれに限らず、温度検出手段９を送風路８から分岐する分岐路に設けても同様の効果が得られる。さらに、温度検出手段９をファン１５とモータ制御手段１０との間に配置することもできる。 In the above embodiment, the inker sensor element 20 for detecting the temperature of the air discharged from the fan 15 is provided in the casing 17 of the blower 7. However, the present invention is not limited to this, and the temperature detecting means is not limited thereto. The same effect can be obtained even if 9 is provided in the branch path branched from the air blowing path 8. Further, the temperature detecting means 9 can be arranged between the fan 15 and the motor control means 10.
また、本実施形態では、トリム３の開口部５とブロア７の吸込口６の間に吸込ダクトが設けられていない場合を例示したが、このような場合、上述したように車室内及びパネル内部空間４の空気を吸込んでブロア７のファン１５により攪拌して空気の温度を均一化することができる。さらに、トリム３の開口部５とブロア７の吸込口６の間に吸込ダクトを設けた場合、トリム３の開口部５を介して車室内の空気のみを吸込むと共に、ブロア７のファン１５により攪拌して空気温度を均一化することができる。 Moreover, in this embodiment, although the case where the suction duct was not provided between the opening part 5 of the trim 3 and the suction inlet 6 of the blower 7 was illustrated, in such a case, as above-mentioned, a vehicle interior and a panel inside The air in the space 4 can be sucked and stirred by the fan 15 of the blower 7 to make the temperature of the air uniform. Further, when a suction duct is provided between the opening 5 of the trim 3 and the suction port 6 of the blower 7, only the air in the vehicle compartment is sucked through the opening 5 of the trim 3 and is stirred by the fan 15 of the blower 7. Thus, the air temperature can be made uniform.
本発明は、より正確で、かつ所望の自動空調制御が可能な車両用空調装置を提供できるという効果があるので、車両用空調装置として適用できると共に、その他、一般機械用あるいは産業機械用などの空調装置としても広く適用可能である。 The present invention has the effect of providing a vehicle air conditioner that is more accurate and capable of performing desired automatic air conditioning control. Therefore, the present invention can be applied as a vehicle air conditioner, and for other general machines or industrial machines. It can be widely applied as an air conditioner.
