JP 2003-127641 A

しかしながら、従来の車両用空調装置は、温度センサを交換する際には空調ケースを分解する必要があるため、より詳細には、少なくとも温度センサが見える位置まで蒸発器を空調ケースから引き出す必要があるため、温度センサの交換作業に時間がかかるという問題があった。   However, since the conventional vehicle air conditioner needs to disassemble the air conditioning case when replacing the temperature sensor, more specifically, it is necessary to pull out the evaporator from the air conditioning case to at least a position where the temperature sensor can be seen. Therefore, there is a problem that it takes time to replace the temperature sensor.

本発明は上記点に鑑みて、空調ケースを分解することなく温度センサを交換可能にすることを目的とする。   An object of this invention is to make it possible to replace | exchange a temperature sensor, without disassembling an air-conditioning case in view of the said point.

本発明の第１実施形態について説明する。図１は第１実施形態に係る車両用空調装置における空調ユニットの要部の構成を示す図、図２は図１の装置における温度センサの脱着途中工程を示す図、図３は図１のセンサ取付部材および温度センサを示す分解斜視図である。 (First embodiment)
A first embodiment of the present invention will be described. FIG. 1 is a diagram showing a configuration of a main part of an air conditioning unit in a vehicle air conditioner according to the first embodiment, FIG. 2 is a diagram showing a process of attaching / detaching a temperature sensor in the device of FIG. 1, and FIG. 3 is a sensor of FIG. It is a disassembled perspective view which shows an attachment member and a temperature sensor.

図１〜３に示すように、空調ユニットは、樹脂製の空調ケース１を備えている。空調ケース１は、ブロアユニット（図示せず）から送られた空気を流通させて最終的に車室内に吹き出すための通路１１を形成するものであり、この通路１１中に蒸発器２が設置されている。   As shown in FIGS. 1 to 3, the air conditioning unit includes a resin air conditioning case 1. The air-conditioning case 1 forms a passage 11 through which air sent from a blower unit (not shown) is circulated and finally blown out into the passenger compartment. An evaporator 2 is installed in the passage 11. ing.

空調ケース１には空調ケース１の内外を連通させる開口１２が形成されている。開口１２は、後述する温度センサおよびセンサ取付部材を蒸発器２に対して脱着する際に利用されるものであり、蒸発器２における空気下流側端面２１よりも空気下流側に設けられている。また、空調ケース１には、タッピングスクリュ６が螺合されるタッピング穴１３が開口１２の近傍に形成されている。   The air conditioning case 1 is formed with an opening 12 that communicates the inside and outside of the air conditioning case 1. The opening 12 is used when a temperature sensor and a sensor mounting member described later are attached to and detached from the evaporator 2, and is provided on the air downstream side of the air downstream side end face 21 in the evaporator 2. In the air conditioning case 1, a tapping hole 13 into which the tapping screw 6 is screwed is formed in the vicinity of the opening 12.

蒸発器２は、図示しない圧縮機、凝縮器、受液器、減圧器とともに配管結合された周知の冷凍サイクルを構成する熱交換器であり、蒸発器２は冷媒と空気との間で熱交換して空気を冷却・除湿するものである。具体的には、蒸発器２は、冷媒を流通させる複数のチューブが積層配置され、隣接するチューブ間に空気と冷媒との間の熱交換を促進させる波状のフィンが配置されている。   The evaporator 2 is a heat exchanger constituting a well-known refrigeration cycle that is pipe-coupled with a compressor, a condenser, a receiver, and a decompressor (not shown). The evaporator 2 exchanges heat between refrigerant and air. The air is then cooled and dehumidified. Specifically, in the evaporator 2, a plurality of tubes that circulate the refrigerant are stacked, and wave-shaped fins that promote heat exchange between the air and the refrigerant are arranged between adjacent tubes.

蒸発器２には、ピース３とセンサ取付部材４によって温度センサ５が装着されている。この温度センサ５は、蒸発器２の表面温度に応じた電気信号を出力するセンサ素子５１と、このセンサ素子５１に接続されてセンサ素子５１の電気信号を空調ケース１外のＥＣＵ（図示せず）に伝達するハーネス５２とを備えている。そして、センサ素子５１にて検出された蒸発器２の表面温度の情報は、吹出空気温度、吹出モードなどの各種の空調制御に用いられる。なお、センサ素子５１は、サーミスタを用いることができる。   A temperature sensor 5 is attached to the evaporator 2 by a piece 3 and a sensor mounting member 4. The temperature sensor 5 includes a sensor element 51 that outputs an electric signal corresponding to the surface temperature of the evaporator 2, and an ECU (not shown) that is connected to the sensor element 51 and transmits the electric signal of the sensor element 51 outside the air conditioning case 1. ) And a harness 52 that transmits the information. And the information of the surface temperature of the evaporator 2 detected by the sensor element 51 is used for various air conditioning controls such as the blowing air temperature and the blowing mode. The sensor element 51 can be a thermistor.

センサ取付部材４は、樹脂製であり、円柱状の棒状部４１の一端側に保持部４２を備え、棒状部４１の他端側に蓋４３が設けられている。センサ素子５１は、一部が保持部４２内に収納され、残部が保持部４２から突出している。ハーネス５２は、一部が棒状部４１内に収納され、残部が蓋４３を貫通して外に出ている。蓋４３は、空調ケース１の開口１２を覆うものであり、タッピングスクリュ６を通す貫通穴４４が形成されている。   The sensor mounting member 4 is made of resin, includes a holding portion 42 on one end side of a cylindrical rod-shaped portion 41, and a lid 43 is provided on the other end side of the rod-shaped portion 41. A part of the sensor element 51 is accommodated in the holding part 42, and the remaining part protrudes from the holding part 42. A part of the harness 52 is accommodated in the rod-shaped portion 41, and the remaining portion passes through the lid 43 and goes out. The lid 43 covers the opening 12 of the air conditioning case 1, and a through hole 44 through which the tapping screw 6 is passed is formed.

ピース３は、樹脂製であり、平板状の板部３１には、センサ素子５１が挿入されるセンサ挿入孔３２が形成されている。このセンサ挿入孔３２は、センサ取付部材４が空調ケース１に装着された状態での棒状部４１の長手方向に沿って、換言すると、温度センサの交換時に温度センサ５およびセンサ取付部材４を蒸発器２の空気下流側端面２１と平行に移動させる際の移動方向に沿って、複数個（本例では２個）設けられている。   The piece 3 is made of resin, and a sensor insertion hole 32 into which the sensor element 51 is inserted is formed in the flat plate portion 31. This sensor insertion hole 32 evaporates the temperature sensor 5 and the sensor mounting member 4 along the longitudinal direction of the rod-like portion 41 in a state where the sensor mounting member 4 is mounted on the air conditioning case 1, in other words, when the temperature sensor is replaced. A plurality (two in this example) are provided along the moving direction when moving parallel to the air downstream side end face 21 of the vessel 2.

また、センサ挿入孔３２は、ピース３が蒸発器２に固定された状態において、空気下流側から空気上流側に向かって径が小さくなるテーパ形状になっている。そして、センサ挿入孔３２は、最大径部の径はセンサ素子５１の径よりも十分に大きく、最小径部の径はセンサ素子５１の径よりも僅かに小さくなっている。   Further, the sensor insertion hole 32 has a tapered shape with a diameter decreasing from the air downstream side toward the air upstream side in a state where the piece 3 is fixed to the evaporator 2. In the sensor insertion hole 32, the diameter of the maximum diameter portion is sufficiently larger than the diameter of the sensor element 51, and the diameter of the minimum diameter portion is slightly smaller than the diameter of the sensor element 51.

ピース３は、板部３１の一端面から突出する２つの突起部３３を備えている。そして、この突起部３３を蒸発器２のフィン間に挿入することにより、ピース３が蒸発器２に固定される。また、センサ素子５１の先端部もフィン間に挿入されて、蒸発器２の表面温度を検出可能になっている。   The piece 3 includes two projecting portions 33 that project from one end surface of the plate portion 31. Then, the piece 3 is fixed to the evaporator 2 by inserting the protrusion 33 between the fins of the evaporator 2. Moreover, the front-end | tip part of the sensor element 51 is also inserted between fins, and the surface temperature of the evaporator 2 can be detected now.

次に、温度センサ５の交換作業の手順について説明する。温度センサ５およびセンサ取付部材４を蒸発器２から外す際には、まず、図１の状態からタッピングスクリュ６を外す。   Next, the procedure for replacing the temperature sensor 5 will be described. When removing the temperature sensor 5 and the sensor attachment member 4 from the evaporator 2, first, the tapping screw 6 is removed from the state shown in FIG.

続いて、蓋４３を持って温度センサ５およびセンサ取付部材４をセンサ挿入孔３２の軸線方向（より詳細には、蒸発器２の空気下流側端面２１から遠ざかる向き）に移動させて、センサ素子５１をセンサ挿入孔３２から外す（図２の状態）。この後、温度センサ５およびセンサ取付部材４を空気下流側端面２１と平行に移動させて、温度センサ５およびセンサ取付部材４を開口１２から空調ケース１外に取り出す。   Subsequently, the temperature sensor 5 and the sensor mounting member 4 are moved in the axial direction of the sensor insertion hole 32 (more specifically, the direction away from the air downstream side end face 21 of the evaporator 2) with the lid 43, and the sensor element 51 is removed from the sensor insertion hole 32 (state of FIG. 2). Thereafter, the temperature sensor 5 and the sensor mounting member 4 are moved in parallel with the air downstream side end face 21, and the temperature sensor 5 and the sensor mounting member 4 are taken out of the air conditioning case 1 through the opening 12.

続いて、別途用意した交換用の温度センサ５およびセンサ取付部材４を蒸発器２に装着する。この際には、温度センサ５およびセンサ取付部材４を開口１２から空調ケース１内に挿入し、蓋４３が空調ケースに当たる位置まで温度センサ５およびセンサ取付部材４を空気下流側端面２１と平行に移動させる（図２の状態）。   Subsequently, a separately prepared replacement temperature sensor 5 and sensor mounting member 4 are attached to the evaporator 2. At this time, the temperature sensor 5 and the sensor mounting member 4 are inserted into the air conditioning case 1 from the opening 12, and the temperature sensor 5 and the sensor mounting member 4 are parallel to the air downstream side end surface 21 until the lid 43 hits the air conditioning case. Move (state of FIG. 2).

この後、温度センサ５およびセンサ取付部材４をセンサ挿入孔３２の軸線方向（より詳細には、蒸発器２の空気下流側端面２１に近づく向き）に移動させて、センサ素子５１をセンサ挿入孔３２に挿入し、続いて、タッピングスクリュ６により蓋４３を空調ケース１に固定する。これにより、センサ素子５１はピース３を介して蒸発器２に固定される。因みに、センサ挿入孔３２の最小径部の径はセンサ素子５１の径よりも僅かに小さくなっているため、センサ素子５１は軽圧入状態になる。   Thereafter, the temperature sensor 5 and the sensor mounting member 4 are moved in the axial direction of the sensor insertion hole 32 (more specifically, the direction toward the air downstream end face 21 of the evaporator 2), and the sensor element 51 is moved to the sensor insertion hole. Then, the lid 43 is fixed to the air conditioning case 1 by the tapping screw 6. Thereby, the sensor element 51 is fixed to the evaporator 2 via the piece 3. Incidentally, since the diameter of the minimum diameter portion of the sensor insertion hole 32 is slightly smaller than the diameter of the sensor element 51, the sensor element 51 is in a light press-fit state.

以上の説明から明らかなように、本実施形態によると、空調ケース１を分解することなく温度センサ５を交換することができる。   As apparent from the above description, according to the present embodiment, the temperature sensor 5 can be replaced without disassembling the air conditioning case 1.

また、センサ挿入孔３２を複数個設けているため、センサ素子５１をセンサ挿入孔３２に挿入する際にセンサ素子５１とセンサ挿入孔３２との位置関係がばらついていても、センサ素子５１は複数個のセンサ挿入孔３２のいずれかに挿入される。   In addition, since a plurality of sensor insertion holes 32 are provided, even if the positional relationship between the sensor element 51 and the sensor insertion hole 32 varies when the sensor element 51 is inserted into the sensor insertion hole 32, the plurality of sensor elements 51 are provided. It is inserted into one of the sensor insertion holes 32.

さらに、センサ挿入孔３２をテーパ形状にしているため、センサ素子５１をセンサ挿入孔３２に挿入する際にセンサ素子５１とセンサ挿入孔３２との位置関係がばらついていても、センサ素子５１はセンサ挿入孔３２に容易に挿入される。   Furthermore, since the sensor insertion hole 32 is tapered, even if the positional relationship between the sensor element 51 and the sensor insertion hole 32 varies when the sensor element 51 is inserted into the sensor insertion hole 32, the sensor element 51 is It is easily inserted into the insertion hole 32.

続いて、別途用意した交換用の温度センサ５およびセンサ取付部材４を蒸発器２に装着する。この際には、温度センサ５およびセンサ取付部材４を開口１２から空調ケース１内に挿入し、棒状部４１の一端側が支持部１４に当たる位置まで温度センサ５およびセンサ取付部材４を空気下流側端面２１と平行に移動させる（図４の状態）。   Subsequently, a separately prepared replacement temperature sensor 5 and sensor mounting member 4 are attached to the evaporator 2. At this time, the temperature sensor 5 and the sensor mounting member 4 are inserted into the air conditioning case 1 through the opening 12, and the temperature sensor 5 and the sensor mounting member 4 are moved to the air downstream side end surface until the one end side of the rod-shaped portion 41 hits the support portion 14. 21 is moved parallel to the state (state of FIG. 4).

この後、棒状部４１の中間部がピース３側に凸になるように棒状部４１を折り曲げることにより、保持部４２をセンサ挿入孔３２の軸線方向（より詳細には、蒸発器２の空気下流側端面２１に近づく向き）に移動させて、センサ素子５１をセンサ挿入孔３２に挿入し、続いて、タッピングスクリュ６により蓋４３を空調ケース１に固定する。これにより、センサ素子５１はピース３を介して蒸発器２に固定される。   Thereafter, the holding portion 42 is bent in the axial direction of the sensor insertion hole 32 (more specifically, the air downstream of the evaporator 2) by bending the rod-like portion 41 so that the intermediate portion of the rod-like portion 41 is convex toward the piece 3 side. The sensor element 51 is inserted into the sensor insertion hole 32, and then the lid 43 is fixed to the air conditioning case 1 by the tapping screw 6. Thereby, the sensor element 51 is fixed to the evaporator 2 via the piece 3.

以上の説明から明らかなように、本実施形態によると、空調ケース１を分解することなく温度センサ５を交換することができる。   As apparent from the above description, according to the present embodiment, the temperature sensor 5 can be replaced without disassembling the air conditioning case 1.
