ところが、上記装置では、雨天等の外気と内気の温度差が大きくなる時に、臭 気センサの悪臭検知により吸気が外気導入から内気循環に切り換わると、車室の 設けたフロントガラス等がくもって視界が悪くなるおそれが生じるという問題点 があった。 However, in the above device, when the temperature difference between the outside air and the inside air becomes large, such as in the case of rain, when the intake air switches from the outside air introduction to the inside air circulation due to the bad smell detection by the odor sensor, the windshield installed in the passenger compartment becomes cloudy and the visibility is reduced. However, there is a problem in that
【０００４】 本考案は、上記問題点に鑑みなされたもので、雨天等の時には内気循環への切 り換えを行わずに外気導入状態を維持し、ガラスのくもりを防止することができ る車両用空調機の内外気切換制御装置を提供することを目的とする。The present invention has been made in view of the above-mentioned problems, and in the case of rain or the like, the vehicle can maintain the outside air introduction state without switching to the inside air circulation and prevent the fogging of glass. It is an object of the present invention to provide an inside / outside air switching control device for a vehicle air conditioner.
【０００５】[0005]
上記目的を達成するために、本考案では、外気の状態を検知する臭気センサを 有し、前記臭気センサで検知した外気の状態に応じて、車両内への吸気状態を外 気導入状態又は内気循環状態に切り換え制御する車両用空調機の内外気切換制御 装置において、前記外気中の水分の状態を検知する検知手段と、前記検知された 水分の状態に応じて、前記外気導入状態へ切り換え制御し、かつ前記内気循環状 態への切り換えを抑止制御する制御手段とを具える。 In order to achieve the above object, the present invention has an odor sensor for detecting the state of the outside air, and determines the intake state into the vehicle according to the state of the outside air detected by the odor sensor. In an inside / outside air switching control device for a vehicle air conditioner for switching control to a circulating state, detection means for detecting a state of water in the outside air, and switching control to the outside air introduction state according to the detected state of water And a control means for controlling the switching to the inside air circulation state.
【０００６】[0006]
臭気センサが悪臭を検知しても、雨天の時には、空調コントローラ等の制御手 段によって車両内への吸気状態を外気導入状態に切り換え、その状態を維持する 。 従って、ガラスのくもりを防止でき、良好な視界を確保することができる。 Even if the odor sensor detects a bad odor, when it is raining, the intake air into the vehicle is switched to the outside air introduction state by a control means such as an air conditioning controller, and that state is maintained. Therefore, it is possible to prevent the fogging of the glass and secure a good field of view.
【０００７】[0007]
本考案の実施例を図１乃至図３の図面に基づき説明する。 図１は、本考案に係る車両用空調機の内外気切換制御装置の構成の第１実施例 を示すブロック図である。図において、空調パネルスイッチ１０は、例えば接続 される空調コントローラ１１に空調の全自動制御を行うことを指示する制御スイ ッチや、車内への吸気を外気又は内気に切り換えるように指示する切換スイッチ や、吹き出し風量を指示する風量スイッチ等から構成されている。 An embodiment of the present invention will be described with reference to the drawings of FIGS. 1 is a block diagram showing a first embodiment of the configuration of an inside / outside air switching control device for a vehicle air conditioner according to the present invention. In the figure, an air-conditioning panel switch 10 is, for example, a control switch for instructing a connected air-conditioning controller 11 to perform fully automatic air-conditioning control, and a changeover switch for instructing to switch intake air into the vehicle to outside air or inside air. And an air volume switch for instructing the air volume.
【０００８】 臭気センサ１２は、車両の前方に配設され、上り坂走行時及び渋滞時等に前方 の車両から排出される排気ガス等の悪臭を検知し、その情報（検知信号）を空調 コントローラ１１に送出している。 雨滴センサ１３は、車外の所定位置（例えば、車両上方）に配設され、車外に 降る雨を検知し、その情報（検知信号）を空調コントローラ１１に送出している 。The odor sensor 12 is arranged in front of the vehicle, detects an offensive odor such as exhaust gas emitted from the vehicle in front when the vehicle is traveling uphill or when traffic is congested, and outputs the information (detection signal) to the air conditioning controller. It is sent to 11. The raindrop sensor 13 is arranged at a predetermined position outside the vehicle (for example, above the vehicle), detects rain falling outside the vehicle, and sends the information (detection signal) to the air conditioning controller 11.
【０００９】 内外気切換アクチュエータ１４は、空調コントローラ１１によって駆動制御さ れており、外気を導入するための外気導入路２０と、内気を循環させるための内 気導入路２１との切り換えを行うダンパ２２を移動させる。すなわち、ダンパ２ ２が、アクチュエータ１４の駆動に伴い実線の位置に移動した場合には、ファン ２３の回転によって内気を循環させ、またダンパ２２が、アクチュエータ１４の 駆動に伴い一点鎖線の位置に移動した場合には、ファン２３の回転によって外気 が車の室内に導入される。The inside / outside air switching actuator 14 is drive-controlled by the air conditioning controller 11, and a damper for switching between the outside air introducing passage 20 for introducing outside air and the inside air introducing passage 21 for circulating inside air. Move 22. That is, when the damper 22 moves to the position indicated by the solid line as the actuator 14 is driven, the internal air is circulated by the rotation of the fan 23, and the damper 22 moves to the position indicated by the alternate long and short dash line as the actuator 14 is driven. In that case, the outside air is introduced into the vehicle compartment by the rotation of the fan 23.
【００１０】 空調コントローラ１１は、上記臭気センサ１２及び雨滴センサ１３から検知信 号を取り込んでおり、全自動制御の場合に、臭気センサ１２から悪臭を検知した 旨の検知信号を取り込むと、内外気切換アクチュエータ１４を駆動制御して、ダ ンパ２２を実線の位置に移動させ、内気導入路２１を使用して内気循環を行わせ る。また、空調コントローラ１１は、臭気センサ１２から悪臭を検知しない旨の 信号を取り込むと、上記アクチュエータ１４を駆動制御して、ダンパ２２を一点 鎖線の位置に移動させ、外気導入路２０を使用して外気導入を行わせる。The air conditioning controller 11 takes in the detection signals from the odor sensor 12 and the raindrop sensor 13, and in the case of fully automatic control, if the detection signal indicating that a bad odor is detected is taken in from the odor sensor 12, the inside and outside air The switching actuator 14 is drive-controlled to move the damper 22 to the position indicated by the solid line, and the inside air introduction path 21 is used to circulate the inside air. Further, when the air conditioning controller 11 takes in a signal indicating that the bad smell is not detected from the odor sensor 12, the air conditioning controller 11 drives and controls the actuator 14 to move the damper 22 to the position indicated by the alternate long and short dash line and use the outside air introduction path 20. Introduce outside air.
【００１１】 上記空調コントローラ１１が内気循環を行わせている場合において、雨滴セン サ１３から雨を検知した旨の検知信号を取り込むと、空調コントローラ１１は、 内外気切換アクチュエータ１４を駆動制御して、ダンパ２２を、一点鎖線の位置 に移動させ、外気導入路２０を使用して外気を室内に導入させる。すなわち、空 調コントローラ１１は、雨天時に雨滴センサ１３から雨を検知した旨の検知信号 を取り込むと、臭気センサ１２からの検知信号の有無にかかわらず、雨滴センサ １３からの検知信号に応じて、ダンパ２２を一点鎖線の位置に移動させ、かつそ の状態を維持させている。また、雨滴センサ１３から上記検知信号の入力がなく なると、空調コントローラ１１は、再び臭気センサ１２からの検知信号に応じて 内外気切換制御を行う。In the case where the air conditioning controller 11 is circulating the inside air, when a detection signal indicating that rain is detected is received from the raindrop sensor 13, the air conditioning controller 11 drives and controls the inside / outside air switching actuator 14. , The damper 22 is moved to the position indicated by the alternate long and short dash line, and the outside air is introduced into the room using the outside air introduction passage 20. That is, when the air conditioning controller 11 takes in a detection signal indicating that rain has been detected from the raindrop sensor 13 in the case of rain, the air conditioning controller 11 responds to the detection signal from the raindrop sensor 13 regardless of the presence or absence of the detection signal from the odor sensor 12. The damper 22 is moved to the position indicated by the alternate long and short dash line, and that state is maintained. When the detection signal is no longer input from the raindrop sensor 13, the air conditioning controller 11 again performs the inside / outside air switching control according to the detection signal from the odor sensor 12.
【００１２】 従って、本実施例では、雨天の場合、内気循環への切り換え動作を行わないよ う動作制御し、常に外気導入路２０からの外気を導入することができるので、フ ロントガラス等のくもりを防止することができ、良好な前方視界を確保すること ができる。 なお、本考案では、上記雨滴センサに代えて、例えばワイパを駆動させるワイ パスイッチに連動させることもできる。この場合、空調コントローラ１１は、ワ イパスイッチからワイパオンの信号を取り込むと、図１の場合と同様に、臭気セ ンサからの検知信号の有無にかかわらず、ワイパスイッチからのワイパオンの信 号に応じて、ダンパを一点鎖線の位置に移動させ、かつ上記状態を維持させるこ とができる。また、ワイパスイッチからワイパオフの信号を取り込むと、空調コ ントローラ１１は、再び臭気センサ１２からの検知信号に応じて内外気切換制御 を行う。この例では、従来装備されている部品（ワイパスイッチ）を利用して、 内外気切換制御を行うことが可能になるので、部品点数の増加を防ぐことができ る。Therefore, in the present embodiment, in the case of rain, the operation control is performed so as not to perform the switching operation to the internal air circulation, and the outside air can be always introduced from the outside air introduction path 20, so that the fog of the front glass or the like can be prevented. Can be prevented, and a good forward field of view can be secured. In the present invention, instead of the raindrop sensor, for example, a wiper switch for driving the wiper can be interlocked. In this case, when the air conditioning controller 11 takes in the wiper on signal from the wiper switch, it responds to the wiper on signal from the wiper switch regardless of the presence or absence of the detection signal from the odor sensor, as in the case of FIG. , The damper can be moved to the position indicated by the alternate long and short dash line and the above state can be maintained. Further, when the wiper off signal is fetched from the wiper switch, the air conditioning controller 11 again performs the inside / outside air switching control according to the detection signal from the odor sensor 12. In this example, since the inside / outside air switching control can be performed using the conventionally equipped component (wiper switch), it is possible to prevent an increase in the number of components.
【００１３】 図２は、本考案に係る内外気切換制御装置の構成の第２実施例を示すブロック 図である。なお、図２における本実施例は、ガラスのくもりを直接検知するくも り検知センサ１５を設けた場合を示すものであり、図１と同様の構成部分につい ては、同一符号として説明を省略する。 くもり検知センサ１５は、例えば発光ダイオードと、ホォトダイオードからな り、フロントガラス等の近傍に配設されて、上記ガラスからの反射光量を検知し 、上記反射光量に応じてガラスがくもっている旨の検知信号を、空調コントロー ラ１１に送出している。FIG. 2 is a block diagram showing a second embodiment of the configuration of the inside / outside air switching control device according to the present invention. Note that this embodiment in FIG. 2 shows a case in which a fog detection sensor 15 for directly detecting the fog of glass is provided, and the same components as those in FIG. .. The fog detection sensor 15 is composed of, for example, a light emitting diode and a photo diode, is arranged in the vicinity of the windshield, etc., detects the amount of reflected light from the glass, and indicates that the glass is fogged according to the amount of reflected light. The detection signal is sent to the air conditioning controller 11.
【００１４】 従って、空調コントローラ１１は、上記検知信号を取り込むと、臭気センサ１ ２からの検知信号の有無にかかわらず、くもり検知センサ１５からの検知信号に 応じて内外気切換アクチュエータ１４を駆動制御し、ダンパ２２を一点鎖線の位 置に移動させ、かつその状態を維持させている。また、くもり検知センサ１５か ら上記検知信号の入力がなくなると、空調コントローラ１１は、再び臭気センサ １２からの検知信号に応じて内外気切換制御を行う。Therefore, when the air-conditioning controller 11 takes in the detection signal, the inside / outside air switching actuator 14 is driven and controlled according to the detection signal from the cloudy-state detection sensor 15 regardless of the presence or absence of the detection signal from the odor sensor 12. However, the damper 22 is moved to the position indicated by the alternate long and short dash line and the state is maintained. When the detection signal is no longer input from the cloudy detection sensor 15, the air conditioning controller 11 again performs the inside / outside air switching control according to the detection signal from the odor sensor 12.
【００１５】 これにより、本実施例では、ガラスのくもりを確実に検知し、ガラスがくもっ ている場合には、常に外気導入路２０から外気を導入することができるので、フ ロントガラス等のくもりを防止することができる。 図３は、本考案に係る内外気切換制御装置の構成の第３実施例を示すブロック 図である。なお、図３における本実施例は、図２と同様のくもり検知センサ１５ を設け、デフロスタ１６を作動制御する場合を示すものであり、図２と同様の構 成部分については、同一符号として説明を省略する。Thus, in the present embodiment, it is possible to reliably detect the fogging of the glass, and when the glass is fogged, the outside air can be always introduced from the outside air introduction passage 20, so that the fogging of the front glass or the like can be prevented. Can be prevented. FIG. 3 is a block diagram showing a third embodiment of the configuration of the inside / outside air switching control device according to the present invention. Note that the present embodiment in FIG. 3 shows a case in which the cloudiness detection sensor 15 similar to that in FIG. 2 is provided to control the operation of the defroster 16, and the same components as in FIG. Is omitted.
【００１６】 空調コントローラ１１は、臭気センサ１２及びくもり検知センサ１５から検知 信号を取り込んでおり、全自動制御の場合に、臭気センサ１２から悪臭を検知し た旨の検知信号を取り込むと、内外気切換アクチュエータ１４を駆動制御して、 ダンパ２２を実線の位置に移動させ、内気導入路２１を使用して内気循環を行わ せる。この場合に、空調コントローラ１１は、くもり検知センサ１５からガラス がくもっている旨の検知信号を取り込むと、デフロスタ１６のみを作動制御する 。そして、くもり検知センサ１５から上記検知信号の入力がなくなると、空調コ ントローラ１１は、デフロスタ１６の作動を停止させる制御を行う。また、上記 デフロスタ１６の作動制御中に、空調コントローラ１１は、これと並行して臭気 センサ１２からの検知信号に応じた内外気切換制御を行う。The air conditioning controller 11 takes in detection signals from the odor sensor 12 and the cloudy detection sensor 15, and in the case of fully automatic control, if a detection signal indicating that a bad odor has been detected is taken in from the odor sensor 12, the inside / outside air The switching actuator 14 is drive-controlled to move the damper 22 to the position indicated by the solid line, and the inside air introduction path 21 is used to circulate the inside air. In this case, when the air conditioning controller 11 takes in the detection signal indicating that the glass is fogged from the fog detection sensor 15, it controls only the defroster 16. Then, when the detection signal is not input from the cloudiness detection sensor 15, the air conditioning controller 11 performs control to stop the operation of the defroster 16. Further, during the operation control of the defroster 16, the air conditioning controller 11 concurrently performs the inside / outside air switching control according to the detection signal from the odor sensor 12.
【００１７】 これにより、本実施例では、ガラスのくもりを検知すると、内外気切換制御と は別に、デフロスタ１６を作動させて、ガラスのくもりを直接除去することがで きるので、ガラスのくもりを確実に防止することができる。 なお、本実施例では、ガラスのくもりを、デフロスタ１６を作動させることに よって除去するようにしたが、本考案はこれに限らず、例えば上記デフロスタ１ ６の作動制御とともに、くもり検知センサ１５からの検知信号に応じて、ダンパ を外気導入状態に切換える切換制御も同時に行うようにすることも可能である。 この場合には、ガラスのくもり防止をさらに確実に向上させることができる。Thus, in the present embodiment, when the cloud of the glass is detected, the defroster 16 can be operated to directly remove the cloud of the glass, in addition to the inside / outside air switching control, so that the cloud of the glass can be removed. It can be surely prevented. In the present embodiment, the cloud of the glass is removed by operating the defroster 16, but the present invention is not limited to this. For example, the operation of the defroster 16 is controlled and the cloud detection sensor 15 is used. It is also possible to simultaneously perform switching control for switching the damper to the outside air introduction state according to the detection signal of. In this case, the prevention of fogging of the glass can be more surely improved.
