Description
【０００１】[0001]
本考案は、自動車用空調装置に関するものである。 The present invention relates to a vehicle air conditioner.
【０００２】[0002]
従来、自動車用空調装置としては、例えば、上流側を車室内および車室外に選 択的に連通する一方、下流側を車室内に連通するとともに、車室内または車室外 の空気を選択する選択装置を備えた送風ユニットと、この送風ユニットの下流側 に配した空気清浄フィルタと、車外に設けた空気の汚染度を検出するガスセンサ とからなるものがある。そして、前記ガスセンサが車外空気の汚染度を検出し、 その汚染度に応じて前記選択装置が空気の流路を切り換え、外気導入状態または 内気導入状態とする。 Conventionally, as an air conditioner for a vehicle, for example, a selection device that selectively communicates the upstream side with the vehicle interior and the vehicle exterior, while communicating the downstream side with the vehicle interior, and selects the air inside or outside the vehicle interior There is an air blower unit provided with the air blower unit, an air cleaning filter arranged on the downstream side of the air blower unit, and a gas sensor provided outside the vehicle for detecting the degree of air pollution. Then, the gas sensor detects the degree of pollution of the air outside the vehicle, and the selection device switches the flow path of the air according to the degree of pollution to establish the outside air introduction state or the inside air introduction state.
【０００３】[0003]
しかしながら、車外空気の汚染度は環境の変化に応じて頻繁に変化するので、 これにつれて選択装置も頻繁に動作する。このため、選択装置の切換音や変化す る空気の吸い込み音が耳障りであり、使い心地が悪いという問題点があった。 However, the pollution degree of the air outside the vehicle changes frequently in response to changes in the environment, and accordingly, the selection device also frequently operates. Therefore, the switching sound of the selection device and the changing air suction sound are unpleasant and uncomfortable to use.
【０００４】 そこで、本考案は、前記問題点に鑑み、耳障りな音が少なく、使い心地の良い 自動車用空調装置を提供することを目的とする。In view of the above problems, it is an object of the present invention to provide an automobile air conditioner that produces less harsh sound and is comfortable to use.
【０００５】[0005]
本考案にかかる自動車用空調装置は、前記目的を達成するため、上流側を車室 内および車室外に選択的に連通する一方、下流側を車室内に連通するとともに、 車室内または車室外の空気を選択する選択装置を備えた送風ユニットと、外気導 入流路内に配した空気清浄フィルタと、空気の汚染度を検出するガスセンサとか らなり、このガスセンサが検出した空気の汚染度が所定値以上となったときに、 前記選択装置によって内気導入状態を維持する自動車用空調装置において、前記 ガスセンサを、前記空気清浄フィルタの下流側に配した構成としてある。 In order to achieve the above-mentioned object, the vehicle air conditioner according to the present invention selectively communicates the upstream side with the inside and the outside of the vehicle compartment, while communicating the downstream side with the inside of the vehicle and the inside or outside the vehicle. It consists of an air blower unit equipped with a selection device for selecting air, an air cleaning filter placed in the outside air inlet flow path, and a gas sensor that detects the degree of air pollution.The degree of air pollution detected by this gas sensor is a specified value. In the above case, the gas sensor is arranged downstream of the air cleaning filter in an automobile air conditioner that maintains the inside air introduction state by the selection device.
【０００６】[0006]
したがって、本考案によれば、空気清浄フィルタを通過した空気の汚染度を、 ガスセンサが検出することになる。 Therefore, according to the present invention, the gas sensor detects the degree of pollution of the air that has passed through the air cleaning filter.
【０００７】[0007]
次に、本考案にかかる自動車用空調装置の一実施例を図１を参照しながら説明 する。 本実施例にかかる自動車用空調装置は、送風ユニット１０と、この送風ユニッ ト１０の下流側に配した空気清浄フィルタ２０と、さらに、この空気清浄フィル タ２０の下流側に配したガスセンサ２１とからなるものである。 Next, an embodiment of an automobile air conditioner according to the present invention will be described with reference to FIG. The air conditioner for an automobile according to this embodiment includes a blower unit 10, an air cleaning filter 20 arranged on the downstream side of the air blowing unit 10, and a gas sensor 21 arranged on the downstream side of the air cleaning filter 20. It consists of
【０００８】 送風ユニット１０には、選択装置である内外気切換用ダンパ１１が回動自在に 設けられているとともに、ブロア１２が設けられている。そして、図示しない駆 動機構を介して所定の位置まで前記ダンパ１１を回動し、かつ、ブロア１２を回 動させることにより、車内に連通する吸い込み口１３から内気を循環させ、また は、車外に連通する吸い込み口１４から外気を取り入れるようになっている。The blower unit 10 is provided with an inside / outside air switching damper 11, which is a selection device, so as to be rotatable, and a blower 12. Then, by rotating the damper 11 to a predetermined position and rotating the blower 12 via a driving mechanism (not shown), the inside air is circulated from the suction port 13 communicating with the inside of the vehicle or the outside of the vehicle. The outside air is taken in through the suction port 14 communicating with the.
【０００９】 空気清浄フィルタ２０は、前記送風ユニット１０の下流側に位置する排出口１ ５の近傍に配されている。The air cleaning filter 20 is arranged near the exhaust port 15 located on the downstream side of the blower unit 10.
【００１０】 ガスセンサ２１は、前記フィルタ２０を通過した空気の汚染度、例えば、低濃 度の可燃性ガス，タバコの煙などを検出し、検出信号を制御手段２２に送出する ものである。より具体的なものとしては、例えば、フィガロガスセンサ（ＴＧＳ ８００）等が挙げられる。The gas sensor 21 detects the degree of pollution of the air that has passed through the filter 20, for example, a flammable gas of low concentration, cigarette smoke, etc., and sends a detection signal to the control means 22. More specific examples include a Figaro gas sensor (TGS 800) and the like.
【００１１】 そして、前記制御手段２２に送出されたガスセンサ２１からの検出信号は、制 御手段２２内において基準値と比較され、汚染度が基準値を越えた場合に図示し ない駆動機構を介してダンパ１１を回動させることにより、車外に連通する吸い 込み口１４を閉じ、車内に連通する吸い込み口１３を開放して内気導入状態とし 、この状態を維持する。Then, the detection signal from the gas sensor 21 sent to the control means 22 is compared with a reference value in the control means 22, and when the pollution degree exceeds the reference value, a drive mechanism (not shown) is used. The damper 11 is rotated to close the suction port 14 that communicates with the outside of the vehicle, and open the suction port 13 that communicates with the inside of the vehicle to bring the inside air into the inside state and maintain this state.
【００１２】 なお、前述の実施例では、送風ユニット１０の下流側に空気清浄フィルタ２０ を設ける場合について説明したが、必ずしもこれに限らず、フィルタ２０は外気 導入流路内に設ければよく、例えば、外気を導入する吸い込み口１４の外側、ま たは、送風ユニット１０内の外気導入流路内に設けてもよい。In the above-described embodiment, the case where the air cleaning filter 20 is provided on the downstream side of the blower unit 10 has been described, but the present invention is not limited to this, and the filter 20 may be provided in the outside air introduction flow path. For example, it may be provided outside the suction port 14 for introducing the outside air, or in the outside air introducing passage in the blower unit 10.
【００１３】[0013]
以上の説明から明らかなように、本考案によれば、車外の空気の汚染度が著し く高い場合であっても、ガスセンサは、空気清浄フィルタが予め清浄にした空気 の汚染度を検出するので、車外の空気の汚染度が著しく高い場合を除き、ダンパ は回動しない。このため、従来例のように外気の汚染度の変化に応じてダンパが 頻繁に回動しないので、耳障りな音が少なくなり、使い心地の良い自動車用空調 装置が得られるという効果がある。 As is clear from the above description, according to the present invention, the gas sensor detects the pollution level of the air previously cleaned by the air cleaning filter even when the pollution level of the air outside the vehicle is extremely high. Therefore, the damper does not rotate unless the air pollution outside the vehicle is extremely high. For this reason, unlike the conventional example, the damper does not rotate frequently according to the change in the degree of pollution of the outside air, so that annoying noise is reduced, and a comfortable air-conditioning system for automobiles can be obtained.
