Description

車両用空調装置vehicle air conditioner
 本発明は、車両用空調装置に関するものである。 The present invention relates to a vehicle air conditioner.
 従来、車室内の空気(内気)と車室外の空気(外気)を同時に導入可能であり、内気と外気を仕切って流すことができる2層流構造を有する車両用空調装置が知られている。この車両用空調装置は、送風機と熱交換器を収容するケーシングを備えており、内外気2層流モードの場合には、ケーシングの下層に内気を導入し、ケーシングの上層に外気を導入して、夫々熱交換器を通した後、ケーシングの下層に導入した空気を足元付近(フット吹出口)に供給する一方、ケーシングの上層に導入した空気をデフロスタ吹出口に供給することで、フロントガラスの曇りを抑制しながら、暖房効率を向上させている(下記特許文献1参照)。 Conventionally, there is known a vehicle air conditioner that has a two-layer flow structure that can simultaneously introduce the air inside the vehicle (inside air) and the air outside the vehicle (outside air), and separate the inside air from the outside air. This vehicle air conditioner has a casing that accommodates a blower and a heat exchanger. In the case of the inside/outside air two-layer flow mode, inside air is introduced into the lower layer of the casing and outside air is introduced into the upper layer of the casing. After passing through the heat exchangers, the air introduced into the lower layer of the casing is supplied to the vicinity of the foot (foot outlet), while the air introduced into the upper layer of the casing is supplied to the defroster outlet, thereby Heating efficiency is improved while suppressing fogging (see Patent Document 1 below).
特開2018-144532号公報JP 2018-144532 A
 前述した車両用空調装置は、ケーシングの内部に熱交換器やエアミックスドアなど部品を配備するため、ケーシングを複数の分割体で形成し、分割状態で内部に各種部品を収納して、その後分割体を結合し固定具(ネジなど)で固定することで、内部に熱交換器等を収納したケーシングを完成させている。 In the vehicle air conditioner described above, parts such as a heat exchanger and an air mix door are arranged inside the casing, so the casing is formed of a plurality of divided bodies, and various parts are stored inside in the divided state, and then divided. By connecting the bodies and fixing them with fixtures (screws, etc.), a casing containing a heat exchanger and the like is completed.
 このような車両用空調装置において、前述した2層流構造にするには、ケーシングの内部に上層と下層を仕切る仕切り壁を設ける必要があり、ケーシングの中央付近、特に、エアミックドアの稼働部付近は、分割体の内側にリブ状に突出する仕切り壁が互いに突き合わされる部分になるので、そこには固定部を設けることができない構造になっている。 In such a vehicle air conditioner, in order to achieve the above-mentioned two-layer flow structure, it is necessary to provide a partition wall inside the casing to separate the upper layer and the lower layer. Since the rib-shaped partition walls protruding inside the divided body are the portions where they abut each other, the structure is such that a fixed portion cannot be provided there.
 このため、ケーシング内への空気の導入でケーシング内の圧力が高まると、仕切り壁の突き合わせ箇所が離れて、風漏れが生じやすくなり、所望のエアミックス状態を得ることができなくなったり、隙間を通る風により笛吹音が発生したりするといった問題が生じる。また、上記のような風漏れが生じると、2層に分かれている内気と外気がケーシング内で混ざり、曇り除去能力(窓晴れ性能)の低下や、暖房性能が低下するといった問題も生じる。更に、ケーシングの中央付近で分割体の固定がなされないことで、分割体から成るケーシングを強固に固定できず、ケーシング自体の強度を高められないという問題もあった。 For this reason, when the pressure inside the casing increases due to the introduction of air into the casing, the abutted portions of the partition walls separate, making it easier for air to leak, making it impossible to obtain the desired air mix state, or creating gaps. There is a problem that a whistling sound is generated by the passing wind. In addition, if the wind leakage as described above occurs, the inside air and the outside air, which are divided into two layers, will mix in the casing, causing problems such as a decrease in defogging ability (window clearing performance) and a decrease in heating performance. Furthermore, since the divided body is not fixed near the center of the casing, the casing made up of the divided bodies cannot be firmly fixed, and the strength of the casing itself cannot be increased.
 本発明は、このような問題に対処することを課題としている。すなわち、2層流構造のケーシングを備えた車両用空調装置において、ケーシングの中央付近やエアミックスドアの稼働部付近に固定部を設けることで、所望のエアミックス状態を得ることができ、隙間を通る風による暖房能力の低下や曇り除去能力の低下或いは騒音といった問題を抑制することができ、また、ケーシングの強度を高めることができる車両用空調装置を提供すること、を課題としている。 The object of the present invention is to deal with such problems. That is, in a vehicle air conditioner having a casing with a two-layer flow structure, a desired air mix state can be obtained by providing a fixed portion near the center of the casing or near the operating portion of the air mix door, and the gap can be reduced. It is an object of the present invention to provide a vehicle air conditioner capable of suppressing problems such as reduction in heating capacity, reduction in defogging capacity, and noise caused by passing wind, and capable of increasing the strength of a casing.
 このような課題を解決するために、本発明は、以下の構成を具備するものである。
 複数の分割ケーシングを結合することで、内部に複数の熱交換器を収容するケーシングを備え、前記ケーシングの内部に、第1送風空間と第2送風空間を仕切る仕切り部を設けた車両用空調装置であって、前記仕切り部は、前記複数の熱交換器における風上側の第1熱交換器と風下側の第2熱交換器の間に、前記第1送風空間側の仕切り壁と前記第2送風空間側の仕切り壁で囲まれた囲み壁部を有し、前記囲み壁部の内側に、前記複数の分割ケーシングを固定する固定部を設けたことを特徴とする車両用空調装置。
In order to solve such problems, the present invention has the following configurations.
A vehicular air conditioner comprising a casing for housing a plurality of heat exchangers therein by joining a plurality of divided casings, and a partition section for partitioning a first blowing space and a second blowing space inside the casing. The partition part is provided between the first heat exchanger on the windward side and the second heat exchanger on the leeward side in the plurality of heat exchangers, and the partition wall on the side of the first ventilation space and the second heat exchanger. A vehicular air conditioner, comprising: an enclosing wall portion surrounded by a partition wall on a blowing space side; and a fixing portion for fixing the plurality of divided casings is provided inside the enclosing wall portion.
 このような特徴を備えた本発明は、2層流構造のケーシングを備えた車両用空調装置において、ケーシングの中央付近やエアミックスドアの稼働部付近に固定部を設けることができるようになり、風漏れを抑止して、所望のエアミックス状態を得ることができ、隙間を通る風による暖房能力の低下や曇り除去能力の低下或いは騒音といった問題を抑制することができる。また、ケーシングを強固に固定することでケーシング自体の強度を高めることができる。 The present invention having such features can provide a fixed portion near the center of the casing and near the operating portion of the air mix door in a vehicle air conditioner equipped with a casing having a two-layer flow structure. A desired air mix state can be obtained by suppressing wind leakage, and problems such as deterioration of heating performance, deterioration of defogging performance, and noise caused by wind passing through the gap can be suppressed. Further, by firmly fixing the casing, the strength of the casing itself can be increased.

 以下、図面を参照して本発明の実施形態を説明する。以下の説明で、異なる図における同一符号は同一機能の部位を示しており、各図における重複説明は適宜省略する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different figures denote portions having the same function, and duplication of description in each figure will be omitted as appropriate.
 図1に示すように、車両用空調装置1は、空気取入部1Aと送風温調部1Bを有する。空気取入部1Aは、図示省略した送風機によって、車室外の空気(外気)と車室内の空気(内気)を取り込んで、送風温調部1Bに送り込む。送風温調部1Bは、ケーシング10を備えており、空気取入部1Aは、ケーシング10に対して外気又は内気を導入する。なお、空気取入部1Aは、ケーシング10に対して一体に設けてもよいし別体にしてもよい。 As shown in FIG. 1, the vehicle air conditioner 1 has an air intake section 1A and a blower temperature control section 1B. The air intake unit 1A takes in air outside the vehicle (outside air) and air inside the vehicle (inside air) by a blower (not shown), and sends the air to the blower temperature control unit 1B. The blower temperature control section 1B has a casing 10, and the air intake section 1A introduces outside air or inside air into the casing 10. As shown in FIG. The air intake portion 1A may be provided integrally with the casing 10 or may be provided separately.
 車両空調装置1におけるケーシング10は、ケーシング10内の送風流路を第1送風空間10Aと第2送風空間10Bに仕切る仕切り部100を備えている。第1送風空間10Aと第2送風空間10Bは、例えば、車両用空調装置1を車両に搭載した際に、上層と下層にすることができる。 The casing 10 in the vehicle air conditioner 1 includes a partition portion 100 that partitions the airflow passage in the casing 10 into the first airflow space 10A and the second airflow space 10B. 10 A of 1st ventilation spaces and the 2nd ventilation space 10B can be made into an upper layer and a lower layer, for example, when the vehicle air conditioner 1 is mounted in a vehicle.
 前述した空気取入部1Aによってケーシング10に導入される空気は、第1送風空間10Aと第2送風空間10Bの夫々に送られる。一例としては、第1送風空間10Aに外気を導入し、第2送風空間10Bに内気を導入することができるが、空気取入部1Aに設けられる切り替え機構によって、第1送風空間10Aと第2送風空間10Bの両方に外気又は内気を導入するようにしてもよく、また、第1送風空間10Aに内気を導入し、第2送風空間に外気を導入するようにしてもよい。 The air introduced into the casing 10 by the air intake portion 1A described above is sent to each of the first ventilation space 10A and the second ventilation space 10B. As an example, the outside air can be introduced into the first ventilation space 10A and the inside air can be introduced into the second ventilation space 10B.

 囲み壁部110の周囲には、流量調整部20である第1エアミックスドア21と第2エアミックスドア22とのシール部111,112が設けられている。第1エアミックスドア21は、一端側が揺動自在に軸支され、囲み壁部110の周囲に設けられたシール部111に当接することで、第1熱交換器17を通過した空気が第2熱交換器18に向かう流路を遮断し、第1熱交換器17を通過して第1吹出部(デフロスタ吹出口11とベント吹出口12)に直接向かう流路を開放する。また、第1エアミックスドア21は、シール部111を離れることで、その開度に応じて、第1送風空間10Aを通って第2熱交換器18に向かう空気の流量を調整する。 Around the surrounding wall portion 110, sealing portions 111 and 112 are provided for the first air mix door 21 and the second air mix door 22, which are the flow rate adjusting portion 20. One end of the first air mix door 21 is rotatably supported and contacts a seal portion 111 provided around the surrounding wall portion 110, so that the air passing through the first heat exchanger 17 is The flow path leading to the heat exchanger 18 is blocked, and the flow path passing through the first heat exchanger 17 and directly directed to the first outlet (the defroster outlet 11 and the vent outlet 12) is opened. In addition, the first air mix door 21 is separated from the seal portion 111 to adjust the flow rate of the air toward the second heat exchanger 18 through the first ventilation space 10A according to the degree of opening thereof.
 第2エアミックスドア22も第1エアミックスドア21と同様に、一端側が揺動自在に軸支され、囲み壁部110の周囲に設けられたシール部112に当接することで、第1熱交換器17を通過した空気が第2熱交換器18に向かう流路を遮断し、第1熱交換器17を通過して第2吹出部(フット吹出口13など)に直接向かう流路を開放する。また、第2エアミックスドア22は、シール部112を離れることで、その開度に応じて、第2送風空間10Bを通って第2熱交換器18に向かう空気の流量を調整する。 Similarly to the first air mix door 21, the second air mix door 22 is pivotally supported at one end side so as to be swingable, and by contacting the seal portion 112 provided around the surrounding wall portion 110, the first heat exchange is performed. Blocks the flow path of the air that has passed through the device 17 and goes to the second heat exchanger 18, and opens the flow path that passes through the first heat exchanger 17 and goes directly to the second blowout part (foot blowout port 13, etc.). . In addition, the second air mix door 22 adjusts the flow rate of air directed to the second heat exchanger 18 through the second ventilation space 10B according to the degree of opening by leaving the seal portion 112 .
 シール部111,112は、多角形状をなす囲み壁部110の頂部付近に設けられている。これにより、囲み壁部110の多角形状を変更すれば、シール部111,112の位置を変えることができ、第1エアミックスドア21や第2エアミックスドア22の支持位置等、その他の構造を変更すること無く、囲み壁部110の形状変更を行うだけで、シール部111,112の位置によって決まる、第1エアミックスドア21や第2エアミックスドア22によって開閉される流路の送風量或いは風量割合を適宜設定変更することができる。 The seal portions 111 and 112 are provided near the top of the polygonal surrounding wall portion 110 . Accordingly, by changing the polygonal shape of the surrounding wall portion 110, the positions of the seal portions 111 and 112 can be changed, and other structures such as the support positions of the first air mix door 21 and the second air mix door 22 can be changed. Without changing, only by changing the shape of the surrounding wall portion 110, the air blow amount of the flow path opened and closed by the first air mix door 21 and the second air mix door 22, which is determined by the positions of the seal portions 111 and 112, or The air volume ratio can be appropriately set and changed.
 また、囲み壁部110は、図3に示すように、シール部111が付近に設けられる多角形状の頂部の内角θ1を、第1送風空間10A側の仕切り壁110Aと第2送風空間10B側の仕切り壁110Bの間の頂部の内角θ2より小さくしている。これによると、囲み壁部110の多角形状を第1送風空間10Aと第2送風空間10Bの方向に向けて縦長形状にすることで、囲み壁部110の内側スペースを固定部200に必要な最小空間にしながら、縦長形状の延び縮で前述したシール部111,112の位置を適宜の位置に設定することができる。 Further, as shown in FIG. 3, the surrounding wall 110 has an internal angle θ1 of a polygonal apex near which the seal 111 is provided so that the partition wall 110A on the side of the first ventilation space 10A and the side of the partition wall 110A on the side of the second ventilation space 10B are It is smaller than the internal angle θ2 of the apex between the partition walls 110B. According to this, by making the polygonal shape of the surrounding wall 110 vertically elongated in the direction of the first air blowing space 10A and the second air blowing space 10B, the inner space of the surrounding wall 110 can be reduced to the minimum necessary for the fixing part 200. The positions of the seal portions 111 and 112 described above can be set at appropriate positions by expanding and contracting the vertically long shape while maintaining the space.
 また、囲み壁部110を縦長形状にすることで、囲み壁部110の剛性を高めることができる。これによって、囲み壁部110の内側に形成される固定部200の剛性を高めることができ、ケーシング10の結合強度を高めることができる。 In addition, the rigidity of the surrounding wall portion 110 can be increased by making the surrounding wall portion 110 vertically long. Thereby, the rigidity of the fixing portion 200 formed inside the surrounding wall portion 110 can be increased, and the bonding strength of the casing 10 can be increased.
 なお、図示のケーシング10は、前述したように、第1送風空間10A側にデフロスタ吹出口11とベント吹出口12が設けられ、第2送風空間10B側にフット吹出口13が設けられており、囲み壁部110の風下側の仕切り部100の位置を調整することで、第1送風空間10Aにおける第2熱交換器18の開口割合を、第2送風空間10Bにおける第2熱交換器18の開口割合より小さくしている。 As described above, the illustrated casing 10 is provided with the defroster outlet 11 and the vent outlet 12 on the side of the first ventilation space 10A, and is provided with the foot outlet 13 on the side of the second ventilation space 10B. By adjusting the position of the partition part 100 on the leeward side of the surrounding wall part 110, the opening ratio of the second heat exchanger 18 in the first ventilation space 10A can be adjusted to the opening ratio of the second heat exchanger 18 in the second ventilation space 10B. smaller than the ratio.
 また、図示の例では、囲み壁部110の風上側の仕切り部100の位置と囲み壁部110の風下側の仕切り部100の位置を異なる位置にすることで、第1熱交換器17における第1送風空間10Aと第2送風空間10Bの開口比を、第2熱交換器18における第1送風空間10Aと第2送風空間10Bの開口比とは異なる比率にしている。 In the illustrated example, the position of the partition 100 on the windward side of the enclosing wall 110 and the position of the partition 100 on the leeward side of the enclosing wall 110 are set to different positions, so that the first heat exchanger 17 The opening ratio between the first ventilation space 10A and the second ventilation space 10B is different from the opening ratio between the first ventilation space 10A and the second ventilation space 10B in the second heat exchanger 18 .
 このように、囲み壁部110に対する仕切り部100の位置を調整することで、流量調整部20及びシール部111,112の位置を変えることなく、第1送風空間10Aと第2送風空間10Bに対して所望の風量割合を設定することが可能になる。 By adjusting the position of the partition part 100 with respect to the surrounding wall part 110 in this way, without changing the positions of the flow rate adjusting part 20 and the sealing parts 111 and 112, the first ventilation space 10A and the second ventilation space 10B can be It becomes possible to set the desired air volume ratio by using the

A desired air mix state can be obtained in 10A and the second air blowing space 10B. As a result, it is possible to suppress problems such as reduction in heating capacity, reduction in defogging capacity, and noise due to wind passing through the gap.
 そして、流量調整部20の稼働部付近に固定部200が設けられることで、流量調整部20の動作を安定させることができるので、これによっても所望のエアミックス状態(風量割合など)を得ることができる。また、シール部111,112が設けられる囲み壁部110の形状を変更することで、流量調整部20とのシール部111,112の位置を簡単に変更することができるので、流量調整を簡単に設定変更することが可能になる。 By providing the fixed portion 200 near the operating portion of the flow rate adjusting portion 20, the operation of the flow rate adjusting portion 20 can be stabilized. can be done.
