空調ユニット20は、内外気切替ドア24と、エアミックスドア25と、吹出口切替ドア26,27,28とを更に備えている。
内外気切替ドア24は、外気吸込口12及び内気吸込口13を開閉させる。内外気切替ドア24が図中に実線で示される内気導入位置に位置している場合、外気吸込口12が閉塞されるとともに、内気吸込口13が開口される。この場合、車両用空調装置1は、内気吸込口13から空気通路11内に内気を取り込む内気循環モードとなる。一方、内外気切替ドア24が図中に破線で示される外気導入位置に位置している場合、内気吸込口13が閉塞されるとともに、外気吸込口12が開口される。この場合、車両用空調装置1は、外気吸込口12から空気通路11内に外気を取り込む外気導入モードとなる。 Theair conditioning unit 20 further includes an inside / outside air switching door 24, an air mix door 25, and air outlet switching doors 26, 27, and 28.
The inside / outsideair switching door 24 opens and closes the outside air inlet 12 and the inside air inlet 13. When the inside / outside air switching door 24 is located at the inside air introduction position indicated by a solid line in the drawing, the outside air inlet 12 is closed and the inside air inlet 13 is opened. In this case, the vehicle air conditioner 1 is in an inside air circulation mode in which inside air is taken into the air passage 11 from the inside air suction port 13. On the other hand, when the inside / outside air switching door 24 is located at the outside air introduction position indicated by a broken line in the drawing, the inside air inlet 13 is closed and the outside air inlet 12 is opened. In this case, the vehicle air conditioner 1 is in an outside air introduction mode in which outside air is taken into the air passage 11 from the outside air inlet 12.
内外気切替ドア24は、外気吸込口12及び内気吸込口13を開閉させる。内外気切替ドア24が図中に実線で示される内気導入位置に位置している場合、外気吸込口12が閉塞されるとともに、内気吸込口13が開口される。この場合、車両用空調装置1は、内気吸込口13から空気通路11内に内気を取り込む内気循環モードとなる。一方、内外気切替ドア24が図中に破線で示される外気導入位置に位置している場合、内気吸込口13が閉塞されるとともに、外気吸込口12が開口される。この場合、車両用空調装置1は、外気吸込口12から空気通路11内に外気を取り込む外気導入モードとなる。 The
The inside / outside
エアミックスドア25は、ヒータコア23に流入する空気の風量と、ヒータコア23を迂回する空気の風量との比率を調整する。具体的には、エアミックスドア25の位置は、図中の実線で示される最大暖房位置と、図中に破線で示される最大冷房位置との間で調整することが可能となっている。エアミックスドア25の位置が最大暖房位置である場合、蒸発器22を通過した空気のほとんどがヒータコア23を通過するため、空調用空気の温度が最も上昇する。エアミックスドア25の位置が最大冷房位置である場合、蒸発器22を通過した空気のほとんどがヒータコア23を迂回する。この場合、蒸発器22で冷却された空気がそのまま各吹出口14~16へ流れるため、空調用空気の温度が最も低下する。車両用空調装置1では、エアミックスドア25の開度が最大暖房位置と最大冷房位置との間で調整されることで、空調用空気の温度が調整される。
The air mix door 25 adjusts the ratio between the air volume flowing into the heater core 23 and the air volume bypassing the heater core 23. Specifically, the position of the air mix door 25 can be adjusted between a maximum heating position indicated by a solid line in the drawing and a maximum cooling position indicated by a broken line in the drawing. When the position of the air mix door 25 is the maximum heating position, since most of the air that has passed through the evaporator 22 passes through the heater core 23, the temperature of the air-conditioning air rises most. When the position of the air mix door 25 is the maximum cooling position, most of the air that has passed through the evaporator 22 bypasses the heater core 23. In this case, since the air cooled by the evaporator 22 flows directly to the outlets 14 to 16, the temperature of the air-conditioning air is the lowest. In the vehicle air conditioner 1, the temperature of the air conditioning air is adjusted by adjusting the opening of the air mix door 25 between the maximum heating position and the maximum cooling position.
吹出口切替ドア26~28は、デフロスタ吹出口14、フェイス吹出口15、及びフット吹出口16のそれぞれの開閉状態を切り替える。吹出口切替ドア26~28の少なくとも1つが開状態となることにより、開状態の吹出口から車室内に向けて空調用空気が吹き出される。
The blower outlet switching doors 26 to 28 switch the open / closed states of the defroster blower outlet 14, the face blower outlet 15, and the foot blower outlet 16, respectively. When at least one of the outlet switching doors 26 to 28 is opened, air for air conditioning is blown out from the opened outlet to the vehicle interior.

The operation part 60 is arrange | positioned at the instrument panel of a vehicle, for example. In the operation unit 60, for example, one of the outside air introduction mode and the inside air circulation mode can be selected. In the operation unit 60, the air volume of the air for air conditioning, the temperature of the air for air conditioning, the outlet for the air for air conditioning, and the like can be set. The operation unit 60 outputs these pieces of operation information to the ECU 80.

粉塵センサ70は、空調ダクト10におけるフィルタ17の設置部分に形成された迂回路18に設けられている。迂回路18は、外気吸込口12から取り込まれる外気、あるいは内気吸込口13から取り込まれる内気をフィルタ17を迂回させて流す部分である。粉塵センサ70は、迂回路18を流れる空気に含まれている粉塵の濃度を検出する。 The display unit 61 is a part that displays various information of the vehicle air conditioner 1.

In addition, the display part 61 may use the thing only for the vehicle air conditioner 1. FIG.
Thedust sensor 70 is provided in the bypass 18 formed in the installation part of the filter 17 in the air conditioning duct 10. The bypass circuit 18 is a part that flows the outside air taken in from the outside air inlet 12 or the inside air taken in from the inside air inlet 13 while bypassing the filter 17.

具体的には、粉塵センサ70は、例えば迂回路18に向けて光を照射する発光素子と、光を受光する受光素子とを有している。発光素子から照射される光は、迂回路18を流れる空気に含まれる粉塵により反射される。この反射光が受光素子により受光される。すなわち、受光素子の受光量は、迂回路18内を通過する空気の粉塵濃度に応じて変化する。受光素子は、受光した反射光に応じた電圧信号を出力する。粉塵センサ70は、受光素子の出力電圧に応じた電圧信号を出力する。よって、空調ダクト10内を流れる空気の粉塵濃度に応じて粉塵センサ70の出力信号が変化することになる。
Specifically, the dust sensor 70 has, for example, a light emitting element that emits light toward the bypass 18 and a light receiving element that receives light. The light emitted from the light emitting element is reflected by dust contained in the air flowing through the bypass 18. This reflected light is received by the light receiving element. That is, the amount of light received by the light receiving element changes according to the dust concentration of the air passing through the bypass 18. The light receiving element outputs a voltage signal corresponding to the received reflected light. The dust sensor 70 outputs a voltage signal corresponding to the output voltage of the light receiving element. Therefore, the output signal of the dust sensor 70 changes according to the dust concentration of the air flowing through the air conditioning duct 10.

In the present embodiment, the seating sensor 71 corresponds to an occupant sensor that detects an occupant in the passenger compartment.
TheECU 80 receives detection signals from various sensors and switches for detecting the state of the vehicle.

Further, the output signals of the dust sensor 70, the seating sensor 71, and the door opening / closing sensor 72 are taken into the ECU 80. The ECU 80 acquires the dust concentration information based on the output signal of the dust sensor 70 and displays the acquired dust concentration on the display unit 61. The ECU 80 acquires information on the presence / absence of an occupant in each seat based on the output signal of the seating sensor 71.

ECU80は、ステップS11の処理で否定判断した場合、すなわち車室内に乗員が存在しないと判断した場合には、ステップS12の処理として、車室内の床に堆積した粉塵が舞い上がるように空調ユニット20を制御する舞い上げ制御を実行する。具体的には、ECU80は、空気の風量が最大風量となるように送風機21を制御する。また、ECU80は、デフロスタ吹出口14及びフェイス吹出口15が閉状態となり、且つフット吹出口16が開状態となるように吹出口切替ドア26~28を制御する。換言すれば、ECU80は、空調ダクト10内を流れる空気がフット吹出口16のみから吹き出されるように吹出口切替ドア26~28を制御する。これにより、フット吹出口16から空気が最大風量で送風されるため、図3に示されるように、車室内の床に堆積した粉塵が車室内に舞い上げられる。
If the ECU 80 makes a negative determination in step S11, that is, if it is determined that no occupant is present in the passenger compartment, the ECU 80 sets the air conditioning unit 20 so that dust accumulated on the floor in the passenger compartment rises as the processing in step S12. Executes the control to be controlled. Specifically, the ECU 80 controls the blower 21 so that the air volume becomes the maximum air volume. The ECU 80 controls the outlet switching doors 26 to 28 so that the defroster outlet 14 and the face outlet 15 are closed and the foot outlet 16 is opened. In other words, the ECU 80 controls the air outlet switching doors 26 to 28 so that the air flowing through the air conditioning duct 10 is blown out only from the foot air outlet 16. Thereby, since air is blown with the maximum air volume from the foot blower outlet 16, as shown in FIG. 3, the dust accumulated on the floor in the passenger compartment is lifted into the passenger compartment.
図2に示されるように、ECU80は、ステップS12の処理を実行した後、ステップS13の処理として、舞い上げ制御が完了したか否かを判断する。具体的には、ECU80は、舞い上げ制御の実行を開始した時点から所定時間が経過することをもって、舞い上げ制御が完了したと判断する。所定時間は、予め設定されている時間である。
As shown in FIG. 2, after executing the process of step S12, the ECU 80 determines whether or not the flying-up control is completed as a process of step S13. Specifically, the ECU 80 determines that the raising control is completed when a predetermined time elapses from the time when the execution of the raising control is started. The predetermined time is a preset time.
ECU80は、ステップS13の処理で肯定判断した場合、すなわち舞い上げ制御が完了した場合には、ステップS14の処理として、空調ダクト10及び車室内を空気が循環するように空調ユニット20を制御する内気循環制御を実行する。具体的には、ECU80は、送風機21の風量を最大風量に設定した状態を維持したまま、デフロスタ吹出口14及びフット吹出口16が閉状態となり、且つフェイス吹出口15が開状態となるように吹出口切替ドア26~28を制御する。換言すれば、ECU80は、空調ダクト10内を流れる空気がフェイス吹出口15のみから吹き出されるように吹出口切替ドア26~28を制御する。これにより、フェイス吹出口15から空気が最大風量で送風されるため、車室内に舞い上げられた粉塵が空気と共に内気吸込口13から空調ダクト10内に吸い込まれる。空調ダクト10内に吸い込まれた空気がフィルタ17を通過する際、空気に含まれる粉塵がフィルタ17により捕集されるため、空気が清浄化される。この清浄化された空気がフェイス吹出口15を介して車室内に吹き出されることにより、車室内の空気が徐々に清浄化される。
If the ECU 80 makes an affirmative determination in the process of step S13, that is, if the raising control is completed, as the process of step S14, the internal air that controls the air conditioning unit 20 so that air circulates through the air conditioning duct 10 and the vehicle interior. Execute circulation control. Specifically, the ECU 80 maintains the state in which the air volume of the blower 21 is set to the maximum air volume so that the defroster outlet 14 and the foot outlet 16 are closed and the face outlet 15 is opened. The blower outlet switching doors 26 to 28 are controlled. In other words, the ECU 80 controls the air outlet switching doors 26 to 28 so that the air flowing through the air conditioning duct 10 is blown out only from the face air outlet 15. As a result, air is blown from the face air outlet 15 at the maximum air volume, so that the dust that has risen into the passenger compartment is sucked into the air conditioning duct 10 from the inside air inlet 13 together with the air. When the air sucked into the air conditioning duct 10 passes through the filter 17, dust contained in the air is collected by the filter 17, so that the air is cleaned. The cleaned air is blown out into the vehicle interior via the face outlet 15, whereby the air in the vehicle interior is gradually cleaned.
ECU80は、ステップS11の処理で肯定判断した場合にも、ステップS14の内気循環制御を実行する。すなわち、ECU80は、車室内に乗員が存在する場合には、舞い上げ制御を実行せずに内気循環制御を実行する。
ECU80は、ステップS14の処理を実行した後、ステップS15の処理として、内気循環制御が完了したか否かを判断する。具体的には、ECU80は、内気循環制御の実行を開始した時点から所定時間が経過することをもって、内気循環制御が完了したと判断する。所定時間は、予め設定されている時間である。 TheECU 80 also executes the inside air circulation control in step S14 even when an affirmative determination is made in the process in step S11. That is, when there is an occupant in the vehicle compartment, the ECU 80 executes the inside air circulation control without executing the soaring control.
After executing the process of step S14, theECU 80 determines whether or not the inside air circulation control is completed as a process of step S15. Specifically, the ECU 80 determines that the inside air circulation control has been completed when a predetermined time has elapsed since the start of execution of the inside air circulation control. The predetermined time is a preset time.
ECU80は、ステップS14の処理を実行した後、ステップS15の処理として、内気循環制御が完了したか否かを判断する。具体的には、ECU80は、内気循環制御の実行を開始した時点から所定時間が経過することをもって、内気循環制御が完了したと判断する。所定時間は、予め設定されている時間である。 The
After executing the process of step S14, the
ECU80は、ステップS15の処理で肯定判断した場合には、すなわち内気循環制御が完了した場合には、ステップS16の処理として、粉塵センサ70により検出される粉塵濃度を表示部61に表示する。その後、ECU80は、ステップS17の処理として、通常空調制御を実行する。
ECU80 displays the dust density detected by the dust sensor 70 on the display part 61 as a process of step S16, when an affirmative determination is made in the process of step S15, that is, when the inside air circulation control is completed. Thereafter, the ECU 80 performs normal air conditioning control as the process of step S17.

(2) The ECU 80 controls the air outlet switching doors 26 to 28 so that the air flowing through the air conditioning duct 10 is blown out only from the foot air outlet 16 as the lift-up control. As a result, the dust accumulated on the floor in the passenger compartment can be more accurately raised to the space in the passenger compartment, so that the dust accumulated on the floor in the passenger compartment can be further collected by the filter 17. Therefore, the dust in the passenger compartment can be reduced more accurately.

As a result, the dust accumulated on the floor in the passenger compartment can be more accurately raised to the space in the passenger compartment, so that the dust accumulated on the floor in the passenger compartment can be further collected by the filter 17. Therefore, the dust in the passenger compartment can be reduced more accurately.
(4)ECU80は、着座センサ71により車室内に乗員が存在しないと判断することを条件に、舞い上げ制御を実行する。これにより、粉塵が乗員にかかり難くなるため、乗員に不快感を与え難くなる。

このような構成によれば、乗員が車両を停止させて降車した後に、ステップS12の舞い上げ制御及びステップS14の内気循環制御が実行されるようになる。よって、更に乗員に粉塵がかかり難くなる。
なお、本変形例の車両用空調装置1のように、始動スイッチ73がオフ操作された後に舞い上げ制御及び内気循環制御が実行される場合、内気循環制御が完了した時点では、車両が停止状態であるとともに、車室内に乗員が存在しない状況となっている。このような状況では、ECU80がステップS17の処理として通常空調制御を実行する必要がないため、同処理を割愛してもよい。 According to such a configuration, after the occupant stops the vehicle and gets off the vehicle, the raising control in step S12 and the inside air circulation control in step S14 are executed. As a result, dust is less likely to be applied to the passenger.

In addition, there are no passengers in the passenger compartment. In such a situation, the ECU 80 does not need to execute the normal air conditioning control as the process of step S17, and therefore the process may be omitted.

次に、第2実施形態の車両用空調装置1について説明する。以下、第1実施形態の車両用空調装置1との相違点を中心に説明する。
本実施形態のECU80は、清浄化制御として、図4に示される処理を実行する。すなわち、ECU80は、ステップS11の処理で否定判断した場合、すなわち車室内に乗員が存在しないと判断した場合には、ステップS20の処理として第1舞い上げ制御を実行する。第1舞い上げ制御の制御内容は、図2に示される第1実施形態のステップS12の制御内容と同一である。 Second Embodiment
Next, the vehicle air conditioner 1 of 2nd Embodiment is demonstrated. Hereinafter, it demonstrates centering on difference with the vehicle air conditioner 1 of 1st Embodiment.
ECU80 of this embodiment performs the process shown by FIG. 4 as cleaning control. That is, if theECU 80 makes a negative determination in step S11, that is, if it is determined that no occupant is present in the vehicle interior, the ECU 80 executes the first soaring control as the process in step S20. The control content of the first soaring control is the same as the control content of step S12 of the first embodiment shown in FIG.
次に、第2実施形態の車両用空調装置1について説明する。以下、第1実施形態の車両用空調装置1との相違点を中心に説明する。
本実施形態のECU80は、清浄化制御として、図4に示される処理を実行する。すなわち、ECU80は、ステップS11の処理で否定判断した場合、すなわち車室内に乗員が存在しないと判断した場合には、ステップS20の処理として第1舞い上げ制御を実行する。第1舞い上げ制御の制御内容は、図2に示される第1実施形態のステップS12の制御内容と同一である。 Second Embodiment
Next, the vehicle air conditioner 1 of 2nd Embodiment is demonstrated. Hereinafter, it demonstrates centering on difference with the vehicle air conditioner 1 of 1st Embodiment.
ECU80 of this embodiment performs the process shown by FIG. 4 as cleaning control. That is, if the
ECU80は、ステップS11の処理で肯定判断した場合、すなわち車室内に乗員が存在すると判断した場合には、ステップS21の処理として、第2舞い上げ制御を実行する。具体的には、ECU80は、第2舞い上げ制御として、図5に示される処理を実行する。
すなわち、ECU80は、まず、ステップS210の処理として、フェイス吹出口15から空気を吹き出す。具体的には、ECU80は、空気の風量が最大風量となるように送風機21を制御する。また、ECU80は、デフロスタ吹出口14及びフット吹出口16が閉状態となり、且つフェイス吹出口15が開状態となるように吹出口切替ドア26~28を制御する。換言すれば、ECU80は、空調ダクト10内を流れる空気がフェイス吹出口15のみから吹き出されるように吹出口切替ドア26~28を制御する。これにより、図6に示されるように、清浄済みの空気がフェイス吹出口15から乗員の顔付近に向かって吹き出される。 If theECU 80 makes an affirmative determination in the process of step S11, that is, if it is determined that an occupant is present in the passenger compartment, the ECU 80 executes the second soaring control as the process of step S21. Specifically, the ECU 80 executes the process shown in FIG. 5 as the second flying-up control.
That is, theECU 80 first blows out air from the face outlet 15 as a process of step S210. Specifically, the ECU 80 controls the blower 21 so that the air volume becomes the maximum air volume. Further, the ECU 80 controls the air outlet switching doors 26 to 28 so that the defroster air outlet 14 and the foot air outlet 16 are closed and the face air outlet 15 is opened. In other words, the ECU 80 controls the air outlet switching doors 26 to 28 so that the air flowing through the air conditioning duct 10 is blown out only from the face air outlet 15. Thereby, as FIG. 6 shows, the cleaned air blows off toward the passenger | crew's face vicinity from the face blower outlet 15. As shown in FIG.
すなわち、ECU80は、まず、ステップS210の処理として、フェイス吹出口15から空気を吹き出す。具体的には、ECU80は、空気の風量が最大風量となるように送風機21を制御する。また、ECU80は、デフロスタ吹出口14及びフット吹出口16が閉状態となり、且つフェイス吹出口15が開状態となるように吹出口切替ドア26~28を制御する。換言すれば、ECU80は、空調ダクト10内を流れる空気がフェイス吹出口15のみから吹き出されるように吹出口切替ドア26~28を制御する。これにより、図6に示されるように、清浄済みの空気がフェイス吹出口15から乗員の顔付近に向かって吹き出される。 If the
That is, the
その後、ECU80は、図5に示されるように、ステップS211の処理として、フット吹出口16から空気を吹き出す。具体的には、ECU80は、送風機21の風量を最大風量に設定した状態を維持したまま、フット吹出口16を開状態にする。これにより、フット吹出口16から空気が送風されるため、図6に示されるように、車室内の床に堆積した粉塵が車室内に舞い上げられる。
Thereafter, as shown in FIG. 5, the ECU 80 blows air from the foot outlet 16 as the process of step S <b> 211. Specifically, the ECU 80 opens the foot outlet 16 while maintaining the state where the air volume of the blower 21 is set to the maximum air volume. Thereby, since air is blown from the foot outlet 16, as shown in FIG. 6, the dust accumulated on the floor in the passenger compartment rises into the passenger compartment.
図5に示されるように、ECU80は、ステップS211の処理を実行した後、ステップS212の処理として、舞い上げ制御が完了したか否かを判断する。具体的には、ECU80は、舞い上げ制御の実行を開始した時点から所定時間が経過することをもって、舞い上げ制御が完了したと判断する。所定時間は、予め設定されている時間である。
As shown in FIG. 5, after executing the process of step S <b> 211, the ECU 80 determines whether the flying control is completed as the process of step S <b> 212. Specifically, the ECU 80 determines that the raising control is completed when a predetermined time elapses from the time when the execution of the raising control is started. The predetermined time is a preset time.
ECU80は、ステップS212の処理で肯定判断した場合には、すなわち舞い上げ制御が完了した場合には、ステップS213の処理として、フット吹出口16を閉状態とした後、ステップS214の処理として、フェイス吹出口15を閉状態にする。その後、図4に示されるように、ECU80は、ステップS14以降の処理を実行する。
If the ECU 80 makes an affirmative determination in step S212, that is, if the raising control is completed, the ECU 80 closes the foot outlet 16 as a process in step S213, and then performs a face operation as a process in step S214. The outlet 15 is closed. Thereafter, as shown in FIG. 4, the ECU 80 executes the processes after step S14.
以上説明した本実施形態の車両用空調装置1によれば、以下の(6)に示される作用及び効果を更に得ることができる。
(6)ECU80は、車室内に乗員が存在する場合には、フェイス吹出口15から空気を吹き出しつつ、舞い上げ制御を実行する。これにより、舞い上げ制御により車室内の空間に舞い上がった粉塵が乗員の顔にかかり難くなる。すなわち、乗員の顔付近の粉塵濃度を低減することができるため、乗員の不快感を低減することができる。 According to the vehicle air conditioner 1 of the present embodiment described above, the operation and effects shown in the following (6) can be further obtained.
(6) When an occupant is present in the vehicle compartment, theECU 80 performs the sowing control while blowing air from the face outlet 15. This makes it difficult for the dust that has risen into the vehicle interior space by the soaring control to hit the occupant's face. That is, since the dust concentration near the passenger's face can be reduced, the passenger's discomfort can be reduced.
