Description

本発明は、空調風の吹出し態様が周期的に変化するゆらぎ風を作り出す車両用空調装置に関する。   The present invention relates to a vehicle air conditioner that creates a fluctuating wind whose air-conditioning air blowing mode periodically changes.

従来の車両用空調装置としては、上下に２箇所設けた空調風の吹出口を、一対のプーリ間に周回した無端ベルトの回転に伴って移動する遮蔽膜で交互に閉じることにより、空調風の吹出方向を周期的に変化させてゆらぎ風を作り出すようにしたものがある（例えば、特許文献１参照）。
特開平１０−５８９４３号公報（第５頁、第１図） As a conventional vehicle air conditioner, two air conditioner air outlets provided at the top and bottom are alternately closed by a shielding film that moves in accordance with the rotation of an endless belt that circulates between a pair of pulleys. There is one in which the blowing direction is periodically changed to create a fluctuating wind (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-58943 (page 5, FIG. 1)

しかしながら、かかる従来の車両用空調装置では、周期的に空調風の吹出方向が変化するが、その変化設定が画一的となり、単に一定量の風量をもって吹出方向を変化させるのみであるため、ゆらぎの変化が風量と無関係となって乗員に対して気持の良いゆらぎ風が得られないものであった。   However, in such a conventional vehicle air conditioner, the blowing direction of the conditioned air periodically changes. However, the change setting is uniform, and only the blowing direction is changed with a certain amount of air flow. The change in the air flow was irrelevant to the air volume, and a pleasant fluctuation wind was not obtained for the passengers.

そこで、本発明は気持の良いゆらぎ風を作り出すことができて乗員にリラックス感を与えることができる車両用空調装置を提供するものである。   Therefore, the present invention provides a vehicle air conditioner that can create a pleasant fluctuation wind and can give a passenger a feeling of relaxation.

本発明にあっては、左右の吹出口から吹き出す空調風の吹出し態様を周期的に変化させてゆらぎ風を作り出す空調風制御手段を設けた車両用空調装置において、
空調風制御手段は、ゆらぎ風の時間変化を周期前半と後半で可変とするリラックスモードを備えたことを最も主要な特徴とする。 In the present invention, in the vehicle air conditioner provided with the air conditioning wind control means for periodically changing the blowing mode of the air conditioning wind blown from the left and right outlets to create the fluctuation air,
The most important feature of the conditioned air control means is that it has a relaxation mode in which the time change of the fluctuation wind is variable in the first half and the second half.

本発明の車両用空調装置によれば、空調風制御手段をリラックスモードに設定することにより、空調風の吹出し態様を周期的に変化させるゆらぎ風の時間変化が周期前半と後半で変わるため、乗員にとって気持の良いゆらぎ風が得られてリラックス感を与えることができる。   According to the vehicle air conditioner of the present invention, by setting the air conditioning wind control means to the relax mode, the time change of the fluctuation wind that periodically changes the air blowing mode changes between the first half and the second half of the cycle. A pleasant fluctuation wind can be obtained and give a sense of relaxation.

以下、本発明の実施形態を図面と共に詳述する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１〜図３は本発明にかかる車両用空調装置の第１実施形態を示し、図１は空調装置の吹出口部分の断面平面図、図２は吹出口からの空調風の吹出状態の変化を（ａ），（ｂ）に示す正面図、図３は運転席側の吹出口の風量変化を示す特性図である。   1 to 3 show a first embodiment of a vehicle air conditioner according to the present invention, FIG. 1 is a cross-sectional plan view of an air outlet portion of the air conditioner, and FIG. 2 is a change in a state of blowing air-conditioned air from the air outlet. (A), (b) is a front view, FIG. 3 is a characteristic diagram showing the change in the air volume at the outlet on the driver's seat side.

本実施形態の車両用空調装置１は、図１に示すようにヒーター、エバポレータおよびエアミックスドアなどを経て空気調和された空調風は、メインダクト２から分岐ダクト２ａ〜２ｄを経て複数の吹出口３ａ〜３ｄから車室内に吹き出すようになっている。   In the vehicle air conditioner 1 according to the present embodiment, as shown in FIG. 1, air-conditioned air that has been air-conditioned through a heater, an evaporator, an air mix door, and the like has a plurality of outlets from the main duct 2 through the branch ducts 2 a to 2 d. It blows out into the vehicle compartment from 3a-3d.

前記吹出口３ａ〜３ｄは、図２に示すようにインストルメントパネル４の前面（車室内に面した側）に、運転席の前方と助手席の前方にそれぞれ対応するように２つが１組となって左右方向に配置される。   As shown in FIG. 2, the air outlets 3 a to 3 d are provided on the front surface (side facing the vehicle interior) of the instrument panel 4, so that two of them correspond to the front of the driver seat and the front of the passenger seat, respectively. And arranged in the left-right direction.

従って、前記分岐ダクト２ａ〜２ｄは、それぞれ１組となった吹出口３ａ，３ｂと３ｃ，３ｄとに対応して分岐ダクト２ａ，２ｂと２ｃ，２ｄとに組分けされ、これら分岐ダクト２ａ，２ｂと２ｃ，２ｄとの分岐部分には、それぞれ組となった分岐ダクト２ａ，２ｂと２ｃ，２ｄとに空調風を個別に供給する第１ファン５ａと第２ファン５ｂとが設けられる。   Accordingly, the branch ducts 2a to 2d are grouped into branch ducts 2a, 2b and 2c, 2d corresponding to the outlets 3a, 3b and 3c, 3d, respectively. A first fan 5a and a second fan 5b that individually supply the conditioned air to the branch ducts 2a, 2b, 2c, and 2d that are in pairs are provided at the branch portions of 2b, 2c, and 2d.

そして、前記第１ファン５ａと前記第２ファン５ｂにそれぞれ個別に回転数制御信号を出力する空調風制御手段としてのコントローラ１０を設け、このコントローラ１０からの指令により各組の吹出口３ａ，３ｂと３ｃ，３ｄから吹き出す空調風の吹出し態様を周期的に変化させてゆらぎ風を作り出すようになっている。   And the controller 10 as an air-conditioning wind control means which outputs a rotation speed control signal to each of the first fan 5a and the second fan 5b is provided, and each set of outlets 3a, 3b is provided by a command from the controller 10. The air-conditioning wind blown out from 3c and 3d is periodically changed to create a fluctuating wind.

即ち、本実施形態では図２（ａ），（ｂ）に示すように助手席側の１組の吹出口３ｃ，３ｄと運転席側の１組の吹出口３ａ，３ｂから交互に空調風が吹き出されるようになっており、運転席および助手席に着座する乗員にとっては所定周期毎に空調風が供給・停止され、これがゆらぎ風となる。   That is, in this embodiment, as shown in FIGS. 2 (a) and 2 (b), conditioned air is alternately supplied from a pair of air outlets 3c and 3d on the passenger seat side and a pair of air outlets 3a and 3b on the driver seat side. Air conditioned air is supplied and stopped at predetermined intervals for passengers seated in the driver's seat and passenger seat, and this becomes a fluctuating wind.

そして、このように空調風を供給・停止するゆらぎ風を作り出す前記コントローラ１０には、ゆらぎ風の時間変化を周期前半と後半で可変とするリラックスモードを備えている。   The controller 10 that generates the fluctuation air for supplying / stopping the air-conditioning air is provided with a relaxation mode in which the time change of the fluctuation air is variable in the first half and the second half.

即ち、本実施形態では図２に示すように（ａ）の状態から（ｂ）の状態には早い変化で移行し、これとは逆に（ｂ）の状態から（ａ）の状態にはゆっくりとした変化で移行させ、運転席側の吹出口３ａ，３ｂでは、図３に示すように１周期の前半では風量の立上がりを大きくする一方、後半では風量を徐々に減少させるようになっている。   That is, in the present embodiment, as shown in FIG. 2, the state (a) is shifted to the state (b) with a rapid change, and conversely, the state (b) is slowly changed to the state (a). In the air outlets 3a and 3b on the driver's seat side, as shown in FIG. 3, the rising of the air volume is increased in the first half of one cycle, while the air volume is gradually decreased in the second half. .

また、本実施形態の車両用空調装置１には、前記コントローラ１０に切換えスイッチ１１が設けられ、この切換スイッチ１１を乗員が操作することによりリラックスモードに設定するようになっている。   Further, in the vehicle air conditioner 1 of the present embodiment, a changeover switch 11 is provided in the controller 10, and the changeover switch 11 is set to a relax mode when operated by a passenger.

このとき、切換えスイッチ１１でリラックスモードに切り換えたときには、インジケータなどによってその状態を表示することが望ましい。   At this time, when the changeover switch 11 is used to switch to the relax mode, it is desirable to display the state using an indicator or the like.

以上の構成により本実施形態の車両用空調装置１によれば、切換スイッチ１１を操作してコントローラ１０をリラックスモードに設定することにより、運転席側の吹出口３ａ，３ｂから吹き出す空調風のゆらぎの時間変化が周期前半と後半で変わるため、運転者にとって気持のよいゆらぎ風が得られてリラックス感を得ることができる。   According to the vehicle air conditioner 1 of the present embodiment configured as described above, fluctuations in the conditioned air blown out from the air outlets 3a and 3b on the driver's seat side by operating the changeover switch 11 and setting the controller 10 to the relax mode. Since the change in the time changes between the first half and the second half of the cycle, a pleasant fluctuation wind can be obtained for the driver and a relaxed feeling can be obtained.

図４，図５は本発明の第２実施形態を示し、前記第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べるものとし、図４は吹出口からの空調風の吹出状態の変化を（ａ），（ｂ）に示す正面図、図５は各吹出口の風量変化を示す特性図である。   4 and 5 show a second embodiment of the present invention, in which the same components as those in the first embodiment are denoted by the same reference numerals and redundant description is omitted, and FIG. FIGS. 5A and 5B are front views showing changes in the blown-out state of the conditioned air, and FIG. 5 is a characteristic diagram showing changes in the air volume at each outlet.

本実施形態の車両用空調装置１Ａは、第１実施形態と同様に図４に示すように複数の吹出口３ａ〜３ｄがインストルメントパネル４の前面に、運転席の前方と助手席の前方にそれぞれ対応するように２つが１組となって左右方向に配置され、コントローラ１０からの指令により各組の吹出口３ａ，３ｂと３ｃ，３ｄから吹き出す空調風の吹出し態様を周期的に変化させてゆらぎ風を作り出すようになっている。   As in the first embodiment, the vehicle air conditioner 1A of the present embodiment has a plurality of outlets 3a to 3d in front of the instrument panel 4, as shown in FIG. 4, in front of the driver seat and in front of the passenger seat. The two are arranged in the left-right direction so as to correspond to each other, and the blowing mode of the conditioned air blown out from each pair of outlets 3a, 3b and 3c, 3d is periodically changed according to a command from the controller 10 It is designed to create a fluctuating wind.

そして、コントローラ１０に設定されるリラックスモードは、ゆらぎ風の時間変化を各組の吹出口３ａ，３ｂと３ｃ，３ｄから吹き出す空調風の風量の増加時に早く、減少時にゆっくりと変化するようになっている。   The relaxation mode set in the controller 10 changes quickly when the airflow of the air-conditioning air blown out from each pair of air outlets 3a, 3b, 3c, and 3d increases, and slowly when the airflow decreases. ing.

即ち、本実施形態では図４に示すように吹出口３ａ〜３ｄの全てから空調風を吹き出すようになっており、（ａ）の状態では風量が少ない状態であり、（ｂ）の状態では風量が多い状態であり、（ａ）の状態から（ｂ）の状態には早い変化で移行し、これとは逆に（ｂ）の状態から（ａ）の状態には遅い変化で移行させるようになっている。   That is, in this embodiment, as shown in FIG. 4, the conditioned air is blown out from all of the outlets 3a to 3d. In the state (a), the air volume is small, and in the state (b), the air volume is small. It is a state in which there is a lot, and the state (a) transitions to the state (b) with a fast change, and conversely, the state (b) transitions to the state (a) with a slow change. It has become.

このとき、風量は図５に示すように１周期の前半では短時間Ｔ１のうちにほぼ比例的に風量を増加させる一方、１周期の後半では長時間Ｔ２（Ｔ１＜Ｔ２）でほぼ反比例的に風量を徐々に減少させるようになっている。   At this time, as shown in FIG. 5, in the first half of one cycle, the air volume is increased almost proportionally in the short time T1, while in the second half of one cycle, the air volume is almost inversely proportional to the long time T2 (T1 <T2). The air volume is gradually reduced.

従って、本実施形態の車両用空調装置１Ａによれば、切換スイッチ１１を操作してコントローラ１０をリラックスモードに設定することにより、各吹出口３ａ，３ｂ，３ｃ，３ｄから吹き出す空調風の時間変化が風量の増加時に早く、減少時に遅くなっているので、そのゆらぎ風によりリラックス効果を得ることができるとともに、空調風に伴う騒音が空調風の増減とほぼ比例して変化するので、あたかも寄せては引くという海の波の音に近似させることができるので、リラックス効果を更に大きくすることができる。   Therefore, according to the vehicle air conditioner 1A of the present embodiment, the time change of the conditioned air blown out from the outlets 3a, 3b, 3c, 3d by operating the changeover switch 11 and setting the controller 10 to the relax mode. Since the airflow increases early and decreases when the airflow decreases, the fluctuation effect can provide a relaxing effect, and the noise associated with the conditioned air changes almost in proportion to the increase and decrease of the conditioned air. Since it can be approximated to the sound of the ocean wave of pulling, the relaxation effect can be further increased.

ところで、本発明は前記第１・第２実施形態に例をとって説明したが、これら実施形態に限ることなく本発明の要旨を逸脱しない範囲で他の実施形態を各種採用することができ、例えば、前記各実施形態では吹出口３ａ〜３ｄをインストルメントパネル４に４つ設けたが、その吹出口の数は４つに限ることはなく、また、吹出口の形成部位もインストルメントパネルに限ることなく、車室内の適宜部位に形成したものでもよい。   By the way, the present invention has been described by taking the first and second embodiments as examples. However, the present invention is not limited to these embodiments, and various other embodiments can be adopted without departing from the gist of the present invention. For example, in each said embodiment, although four outlets 3a-3d were provided in the instrument panel 4, the number of the outlets is not restricted to four, Moreover, the formation site of an outlet is also in an instrument panel. Without limitation, it may be formed at an appropriate part in the vehicle interior.

また、一例として第１・第２ファン５ａ，５ｂで空調風を増減させたが、吹出口を開閉制御することにより空調風を増減させることもできる。   In addition, as an example, the conditioned air is increased / decreased by the first and second fans 5a, 5b, but the conditioned air can be increased / decreased by opening / closing the air outlet.
