Description

本発明は、自動車などの車両に搭載され、車室内における冷房および暖房などの空気調和を行う車両用空調装置に関するものであり、特に、熱交換器を収容する空調ケースの組み付け構造に関するものである。 The present invention relates to a vehicle air conditioner that is mounted on a vehicle such as an automobile and performs air conditioning such as cooling and heating in a passenger compartment, and particularly relates to an assembly structure of an air conditioning case that houses a heat exchanger. .

従来、車両に搭載される車両用空調装置の空調ケースとして、内部に収容する蒸発器、ヒータコアなどの熱交換器の組付性を向上させるために空調ケースを２分割もしくは３分割に形成してそれぞれの分割面を組み合わせるように構成しているのが知られている。 Conventionally, as an air conditioning case for a vehicle air conditioner mounted on a vehicle, the air conditioning case is divided into two or three parts in order to improve the assembling property of a heat exchanger such as an evaporator or a heater core accommodated therein. It is known that each divided surface is configured to be combined.

例えば、図１０に示すように、空調ケース１００を右ケース１１０、左ケース１２０、下ケース１３０の３分割に構成したときには、それぞれのケース１１０、１２０、１３０に分割面１１０ａ、１１０ｂ、１２０ａ、１２０ｂ、１３０ｂと締結部１１０ｃ、１２０ｃ、１３０ｃとを形成している。 For example, as shown in FIG. 10, when the air conditioning case 100 is configured to be divided into a right case 110, a left case 120, and a lower case 130, the divided surfaces 110 a, 110 b, 120 a, and 120 b are formed in the respective cases 110, 120, and 130. , 130b and fastening portions 110c, 120c, 130c are formed.

右ケース１１０と左ケース１２０とを組み合わせる分割面１１０ａ、１２０ａは縦方向に形成し、右ケース１１０および左ケース１２０と下ケース１３０とを組み合わせる分割面１１０ｂ、１２０ｂ、１３０ｂは横方向に形成している。 The split surfaces 110a and 120a that combine the right case 110 and the left case 120 are formed in the vertical direction, and the split surfaces 110b, 120b, and 130b that combine the right case 110 and the left case 120 and the lower case 130 are formed in the horizontal direction. Yes.

また、下ケース１３０および左ケース１２０の締結部１３０ｃ、１２０ｃには丸穴が形成され、右ケース１１０の締結部１１０ｃにはネジ部材１４０の下穴が形成されている。そして、これら３点のケース１１０、１２０、１３０を組み合わせて締結するときには、右ケース１１０の分割面１１０ａと左ケース１２０の分割面１２ａとを組み合わせるとともに、これら下面の分割面１１０ｂ、１２０ｂと下ケース１３０の分割面１３０ｂとを組み合わせて一つのネジ部材１４０を用いて締結している。 Further, a round hole is formed in the fastening portions 130 c and 120 c of the lower case 130 and the left case 120, and a pilot hole of the screw member 140 is formed in the fastening portion 110 c of the right case 110. When the three cases 110, 120, and 130 are combined and fastened, the dividing surface 110a of the right case 110 and the dividing surface 12a of the left case 120 are combined, and the dividing surfaces 110b and 120b of these lower surfaces and the lower case are combined. The three split surfaces 130b are combined and fastened using one screw member 140.

しかしながら、上記構成によれば、これら３点のケース１１０、１２０、１３０を締結するときに、ネジ部材１４０の締め付け力が縦方向に作用する。これにより、横方向に形成された分割面１１０ｂ、１２０ｂ、１３０ｂにおいては、その対向する分割面１１０ｂ、１２０ｂ、１３０ｂを閉じる方向に締め付け力が作用されることで、その分割面１１０ｂ、１２０ｂ、１３０ｂの気密性は良好となる。 However, according to the above configuration, when these three cases 110, 120, and 130 are fastened, the fastening force of the screw member 140 acts in the vertical direction. Thereby, in the divided surfaces 110b, 120b, and 130b formed in the lateral direction, a clamping force is applied in a direction to close the opposed divided surfaces 110b, 120b, and 130b, so that the divided surfaces 110b, 120b, and 130b are operated. The airtightness of is good.

ところが、右ケース１１０と左ケース１２０との間に形成された分割面１１０ａ、１２０ａにおいては、その分割面１１０ａ、１２０ａを閉じる方向に締め付け力が作用していないことで、その分割面１１０ａ、１２０ａから風洩れが発生する問題がある。 However, in the split surfaces 110a and 120a formed between the right case 110 and the left case 120, the tightening force does not act in the direction in which the split surfaces 110a and 120a are closed. There is a problem that wind leakage occurs.

そこで、本発明の目的は、上記点を鑑みたものであり、分割面の風洩れを防止することができる車両用空調装置を提供することにある。 Accordingly, an object of the present invention is to provide a vehicle air conditioner that can prevent wind leakage from a divided surface in view of the above points.

また、これら３点の各ケース部１１、１２、１３を重ね合わせてネジ部材１４で締結するときに、縦方向に交差する方向に形成された分割面１１ｂ、１２ｂ、１３ｂにおいては、互いの分割面１１ｂ、１２ｂ、１３ｂを閉じる方向にネジ部材１４の締め付け力が作用されることで、その分割面１１ｂ、１２ｂ、１３ｂの気密性は良好となる。 Further, when the three case portions 11, 12, and 13 are overlapped and fastened by the screw member 14, the divided surfaces 11b, 12b, and 13b formed in the direction intersecting the vertical direction are separated from each other. When the tightening force of the screw member 14 is applied in the direction in which the surfaces 11b, 12b, and 13b are closed, the airtightness of the divided surfaces 11b, 12b, and 13b is improved.

ところが、第１ケース部１１と第２ケース部１２との間に形成された互いに対向する分割面１１ａ、１２ａにおいては、その分割面１１ａ、１２ａを閉じる方向に締め付け力が作用していないことで、その対向する分割面１１ａ、１２ａから風洩れが発生する問題がある。 However, in the split surfaces 11a and 12a that are formed between the first case portion 11 and the second case portion 12 and face each other, no tightening force acts in the direction of closing the split surfaces 11a and 12a. There is a problem that wind leakage occurs from the opposed divided surfaces 11a and 12a.

そこで、本発明では、これら３点の各ケース部１１、１２、１３を締結するときに、縦方向に形成された分割面１１ａ、１２ａを閉じる方向に押圧可能な押圧部である一対のリブ部１２ｄ、１３ｄを形成している。この一対のリブ部１２ｄ、１３ｄは、図１に示すように、締結部１１ｃ、１２ｃ、１３ｃ近傍の分割面１２ｂ、１３ｂの組み合わせ部の一部に形成されている。 Therefore, in the present invention, when these three case portions 11, 12, 13 are fastened, a pair of rib portions that are pressing portions that can be pressed in the direction of closing the split surfaces 11a, 12a formed in the vertical direction. 12d and 13d are formed. As shown in FIG. 1, the pair of rib portions 12d and 13d are formed in a part of the combined portion of the divided surfaces 12b and 13b in the vicinity of the fastening portions 11c, 12c and 13c.

その形状は、互いに重ね合わせることで縦方向に形成された対向する分割面１１ａ、１２ａを閉じる方向に押圧を掛けるように略Ｖ字状からなる凸状のリブ部１３ｄと、その凸状のリブ部１３ｄに嵌め合う凹状のリブ部１２ｄとから形成している。より具体的には、第３ケース部１３に、第２ケース部１２側に突き出した略Ｖ字状からなる凸状のリブ部１３ｄを形成するとともに、第２ケース部１２に、凸状のリブ部１３ｄに嵌め合う略Ｖ字状からなる凹状のリブ部１２ｄを形成している。 The convex rib part 13d which consists of substantially V shape so that it may press in the direction which closes the division | segmentation surfaces 11a and 12a which were formed in the vertical direction by overlapping each other, and the convex rib It is formed from a concave rib portion 12d fitted to the portion 13d. More specifically, the third case portion 13 is formed with a convex rib portion 13d having a substantially V-shape protruding toward the second case portion 12 side, and the second case portion 12 has a convex rib shape. A concave rib portion 12d having a substantially V-shape fitting with the portion 13d is formed.

つまり、３点の各ケース部１１、１２、１３の締結部１１ｃ、１２ｃ、１３ｃをネジ部材１４で締結するときに、略Ｖ字状の凹凸状からなる互いのリブ部１３ｄ、１２ｄが重なり合うことで、縦方向に対向する分割面１１ａ、１２ａを閉じる方向に押圧が掛かるように形成されている。 That is, when the fastening portions 11c, 12c, and 13c of the three case portions 11, 12, and 13 are fastened by the screw member 14, the rib portions 13d and 12d that are substantially V-shaped unevenness overlap each other. Thus, the dividing surfaces 11a and 12a opposed in the vertical direction are formed so as to be pressed in the closing direction.

これによれば、締結部１１ｃ、１２ｃ、１３ｃを締結するときに、縦方向に作用する締め付け力に対する反力が傾斜面に作用することで、第１ケース部１１が第２ケース部１２側に押されるようにして組み付けられる。つまり、対向する分割面１１ａ、１２ａを閉じる方向に押圧されることで分割面１１ａ、１２ａにおける気密性が良好となる。 According to this, when the fastening portions 11c, 12c, and 13c are fastened, the reaction force against the fastening force acting in the vertical direction acts on the inclined surface, so that the first case portion 11 moves toward the second case portion 12 side. It is assembled as if pushed. That is, the airtightness in the division surfaces 11a and 12a becomes favorable by pressing in the direction which closes the division surfaces 11a and 12a which oppose.

なお、本実施形態では、第３ケース部１３に、略Ｖ字状の凸状のリブ部１３ｄを形成するとともに、第２ケース部１２に、凸状のリブ部１３ｄに嵌め合う略Ｖ字状の凹状のリブ部１２ｄを形成させたが、これに限らず、具体的には、図２に示すように、第３ケース部１３に、略Ｖ字状の凸状のリブ部１３ｄを形成するとともに、第１ケース部１１に、凸状のリブ部１３ｄに嵌め合う略Ｖ字状の凹状のリブ部１１ｄを形成させても良い。 In the present embodiment, a substantially V-shaped convex rib portion 13d is formed in the third case portion 13, and a substantially V-shaped shape is fitted in the second case portion 12 to the convex rib portion 13d. However, the present invention is not limited to this, and specifically, a substantially V-shaped convex rib portion 13d is formed in the third case portion 13 as shown in FIG. At the same time, the first case portion 11 may be formed with a substantially V-shaped concave rib portion 11d that fits into the convex rib portion 13d.

ところで、このときには、締結部１１ｃ、１２ｃは、図２に示すように、ネジ部材１４が貫通する丸穴を第１ケース部１１の締結部１１ｃに形成し、ネジ部材１４の下穴を第２ケース部１２の締結部１２ｃに形成するとともに、第３ケース部１３の締結部１３ｃと第２ケース部１２の締結部１２ｃとの間に第１ケース部１１の締結部１１ｃを重ね合わせるように構成している。 By the way, at this time, as shown in FIG. 2, the fastening portions 11 c and 12 c form a round hole through which the screw member 14 passes in the fastening portion 11 c of the first case portion 11. Formed on the fastening portion 12c of the case portion 12 and configured to overlap the fastening portion 11c of the first case portion 11 between the fastening portion 13c of the third case portion 13 and the fastening portion 12c of the second case portion 12. is doing.

次に、以上の構成による空調ケース１０の組み付け方法について説明する。まず、第３ケース部１３内に図示しない送風機、冷房用熱交換器、暖房用熱交換器などを配置する。そして、第３ケース部１３の分割面１３ｂに第２ケース部１２の分割面１２ｂを重ね合わせる。このときに、第２ケース部１２の締結部１２ｃが第３ケース部１３の締結部１３ｂに重なり合う。 Next, a method for assembling the air conditioning case 10 having the above configuration will be described. First, an unillustrated blower, a cooling heat exchanger, a heating heat exchanger, and the like are arranged in the third case portion 13. Then, the dividing surface 12 b of the second case portion 12 is overlapped with the dividing surface 13 b of the third case portion 13. At this time, the fastening portion 12 c of the second case portion 12 overlaps with the fastening portion 13 b of the third case portion 13.

そして、第３ケース部１３の分割面１３ｂに第１ケース部１１の分割面１１ｂを重ね合わせる。このときに、第１ケース部１１の締結部１１ｃが第２ケース部１２の締結部１２ｃに重なり合う。 Then, the dividing surface 11 b of the first case portion 11 is overlapped with the dividing surface 13 b of the third case portion 13. At this time, the fastening portion 11 c of the first case portion 11 overlaps with the fastening portion 12 c of the second case portion 12.

そして、ネジ部材１４を第３ケース部１３の締結部１１ｃの下方から上方に向けてネジ締めを行う。この締結のときに、一対のリブ部１３ｄ、１２ｄが重なり合うことにより、凹状のリブ部１２ｄの分割面１２ａに近い側の傾斜面（図中に示す右側）が凸状のリブ部１３ｄの傾斜面（図中に示す右側）で押圧されることで、第２ケース部１２が第１ケース部１１側に押圧されて空調ケース１０が組み付けられる。 Then, the screw member 14 is screwed upward from below the fastening portion 11 c of the third case portion 13. At the time of this fastening, the pair of rib portions 13d, 12d overlap, so that the inclined surface (right side shown in the drawing) near the dividing surface 12a of the concave rib portion 12d is the inclined surface of the convex rib portion 13d. The second case portion 12 is pressed toward the first case portion 11 side and the air conditioning case 10 is assembled by being pressed at (right side shown in the figure).
