When viewed from below, the main body case 4 has a horizontally long (left-right direction) rectangle. On the front side of the main body case 4, a first air outlet (clean air outlet) 11 and a second air outlet 12 are provided. A first suction port (clean suction port) 13 is provided on the rear surface side of the main body case, and a second suction port 14 is provided on the lower surface side of the main body case 4.
　図４に示すように、本体ケース４内には、第１の吹出口１１と第１の吸込口１３とを連通する第１の送風路（清浄送風路）１５と、第２の吹出口１２と第２の吸込口１４とを連通する第２の送風路１８が形成されている。第１の送風路１５では、第１の吸込口１３から吸い込まれた車内の空気が、順に空気清浄部５、送風部６を介して第１の吹出口１１から車内へ送風される。 As shown in FIG. 4, in the main body case 4, a first air passage (clean air passage) 15 that communicates the first air outlet 11 and the first air inlet 13, and a second air outlet 12. A second air passage 18 that communicates with the second air inlet 14 is formed. In the 1st ventilation path 15, the air in the vehicle inhaled from the 1st inlet 13 is ventilated from the 1st blower outlet 11 to the inside of the vehicle via the air purifying part 5 and the ventilation part 6 in order.
　空気清浄部５は、本体ケース４の後面側の第１の吸込口１３付近に装着されている。空気清浄部５は、一例として、濾材を波状に折り曲げた集塵フィルターである。 The air purifying unit 5 is mounted in the vicinity of the first suction port 13 on the rear surface side of the main body case 4. As an example, the air cleaning unit 5 is a dust collection filter in which a filter medium is bent in a wave shape.
　送風部６は、スクロール形状のケーシング１６と、ケーシングに固定されたモータ２４（図５参照）と、モータ２４によって回転する羽根（図示せず）とを備えている。ケーシング１６は、天面に円形の吸気口（図示せず）を、前面側に四角形の吐出口１７を有している。 The air blower 6 includes a scroll-shaped casing 16, a motor 24 (see FIG. 5) fixed to the casing, and a blade (not shown) that is rotated by the motor 24.

　モータ２４によって羽根が回転すると、車内の空気が、本体ケース４の第１の吸込口１３から、本体ケース４内へ吸い込まれる。この吸い込まれた空気は、空気清浄部５へ送風され、空気清浄部５によって、空気中の埃等が捕集される。空気清浄部５を通過した空気は、ケーシング１６の吸気口を介して、ケーシング１６内へ送風される。そして、ケーシング１６の吐出口１７から、本体ケース４の第１の吹出口１１を介し、車内へ送風される。 When the blades are rotated by the motor 24, the air in the vehicle is sucked into the main body case 4 from the first suction port 13 of the main body case 4. The sucked air is blown to the air cleaning unit 5, and dust or the like in the air is collected by the air cleaning unit 5. The air that has passed through the air cleaning unit 5 is blown into the casing 16 through the intake port of the casing 16. Then, the air is blown from the discharge port 17 of the casing 16 into the vehicle through the first air outlet 11 of the main body case 4.
　第２の送風路１８では、第２の吸込口１４から吸い込まれた車内の空気が、順に粉塵検知部７、第１の基板部９を介して第２の吹出口１２から車内へ送風される。 In the 2nd ventilation path 18, the air in the vehicle inhaled from the 2nd inlet 14 is ventilated in order from the 2nd blower outlet 12 through the dust detection part 7 and the 1st board | substrate part 9 in order. .
　粉塵検知部７は、空気中の粉塵量を測定するものである。粉塵検知部７は、一例として、光散乱式である。 The dust detection unit 7 measures the amount of dust in the air. The dust detection part 7 is a light-scattering type as an example.
　表示部８は、本体ケース４における下面に設けられている。表示部８の表示内容は、粉塵検知部７で計測された値を元に、本体ケース４内に備えられた第２の基板部１０によって制御される。 The display unit 8 is provided on the lower surface of the main body case 4. The display content of the display unit 8 is controlled by the second substrate unit 10 provided in the main body case 4 based on the value measured by the dust detection unit 7.
　第２の基板部１０は、本体ケース４内に備えられ、表示部８の上方に配置されている。 The second substrate unit 10 is provided in the main body case 4 and is disposed above the display unit 8.
　第１の基板部９は、制御基板部分１９と操作用基板部分２０とを有している。制御基板部分１９は、粉塵検知部７からの信号によって送風部６の風量を制御する。操作用基板部分２０は、操作用の複数のスイッチ２１を備えている。この複数のスイッチ２１によって、電源の入り、切り、モードの切替等を行うことができる。 The first substrate portion 9 has a control substrate portion 19 and an operation substrate portion 20. The control board portion 19 controls the air volume of the blower 6 by a signal from the dust detector 7. The operation board portion 20 includes a plurality of operation switches 21. The plurality of switches 21 can be used to turn on / off the power, switch modes, and the like.
　図６は、実施の形態１における車両用空気清浄機を下方から見た展開図である。ここで、本体ケース４内における、部品の配置について説明する。 FIG. 6 is a developed view of the vehicle air cleaner according to the first embodiment as viewed from below. Here, the arrangement of components in the main body case 4 will be described.
　図６に示すように、本体ケース４内における後側（一方の長辺側）には、粉塵検知部７と、空気清浄部５とを備えている。粉塵検知部７は、本体ケース４における後側（一方の長辺側）で、かつ右側（一方の短辺側）に配置されている。空気清浄部５は、本体ケース４における後側（一方の長辺側）で、かつ左側（他方の短辺側）に配置されている。粉塵検知部７と空気清浄部５とは、隣接して配置されている。本体ケース４における長辺方向の空気清浄部５の長さＡは、本体ケース４における長辺方向の粉塵検知部７の長さＢより長い。 As shown in FIG. 6, a dust detection unit 7 and an air cleaning unit 5 are provided on the rear side (one long side) in the main body case 4. The dust detection unit 7 is disposed on the rear side (one long side) and the right side (one short side) of the main body case 4. The air purifier 5 is disposed on the rear side (one long side) and the left side (the other short side) of the main body case 4. The dust detection unit 7 and the air cleaning unit 5 are disposed adjacent to each other. The length A of the long-side air cleaning part 5 in the main body case 4 is longer than the length B of the long-side dust detection part 7 in the main body case 4.
　本体ケース４内における前側（他方の長辺側）には、第１の基板部９と、送風部６と、第２の基板部１０とを備えている。第１の基板部９は、本体ケース４における前側（他方の長辺側）で、かつ右側（一方の短辺側）に配置され、第２の基板部１０は、本体ケース４における前側（他方の長辺側）で、かつ左側（他方の短辺側）に配置されている。送風部６は、第１の基板部９と第２の基板部１０との間に配置され、第１の基板部９と第２の基板部１０の両方に隣接して配置されている。 The front side (the other long side) in the main body case 4 includes a first substrate unit 9, a blower unit 6, and a second substrate unit 10. The first substrate unit 9 is disposed on the front side (the other long side) of the main body case 4 and on the right side (the one short side), and the second substrate unit 10 is disposed on the front side (the other side of the main body case 4). On the long side) and on the left side (the other short side). The air blowing unit 6 is disposed between the first substrate unit 9 and the second substrate unit 10 and is disposed adjacent to both the first substrate unit 9 and the second substrate unit 10.
　以上のように、粉塵検知部７と空気清浄部５とは隣接する構成である。また、送風部６は第１の基板部９と第２の基板部１０との間に配置され、第１の基板部９、第２の基板部１０の両方に隣接する構成である。これより、部品同士が上下方向に重なることなく、無駄な空間のない部品配置が可能となる。 As described above, the dust detection unit 7 and the air cleaning unit 5 are adjacent to each other. Further, the air blowing unit 6 is disposed between the first substrate unit 9 and the second substrate unit 10 and is adjacent to both the first substrate unit 9 and the second substrate unit 10. As a result, the components can be arranged without wasteful space without overlapping the components in the vertical direction.
　また、本体ケース４における左右方向（長辺方向）の送風部６の長さＣは、本体ケース４における左右方向（長辺方向）の空気清浄部５の長さＡより短く、送風部６は、第１の基板部９と第２の基板部１０との間に配置される。これにより、本体ケース４における左右方向（長辺方向）の送風部６の中心Ｅ（吸気口の中心）と、空気清浄部５の中心Ｄとの距離が縮まり、送風部６の中心Ｅから空気清浄部５の両端までの距離がＡ／２（同一）に近づく。つまり、空気清浄部５の左右方向（長辺方向）における風量が均一に近づき、空気清浄部５全体でより均一に空気中の埃等を捕集できる。結果として、小型化、薄型化できる部品配置となり、捕集風量の低下を抑制する車両用空気清浄機を提供することができる。 Moreover, the length C of the air blower 6 in the left-right direction (long side direction) in the main body case 4 is shorter than the length A of the air purifier 5 in the left-right direction (long side direction) in the main body case 4. , Between the first substrate unit 9 and the second substrate unit 10. As a result, the distance between the center E of the air blower 6 in the left-right direction (long side direction) in the main body case 4 and the center D of the air purifier 5 is reduced, and the air from the center E of the air blower 6 is reduced. The distance to the both ends of the cleaning part 5 approaches A / 2 (same). That is, the air volume in the left-right direction (long side direction) of the air cleaning unit 5 approaches uniformly, and dust or the like in the air can be collected more uniformly in the entire air cleaning unit 5. As a result, it is possible to provide a vehicle air cleaner that can be reduced in size and thickness and can suppress a reduction in the amount of collected air.
　ここで、粉塵検知部７の本体ケース４における右側（一方の短辺側）から、空気清浄部５の本体ケース４における左側（他方の短辺側）までの長さを長さＦと定義する。また、第１の基板部９の本体ケース４における右側（一方の短辺側）から、第２の基板部１０の本体ケース４における左側（他方の短辺側）までの長さを長さＧと定義する。この時、長さＦと長さＧは実質的に同じである。なお実質的に同じとは、長さＦに対して、長さＧが、８０％から１２０％の間の長さであることを意味する。 Here, the length from the right side (one short side) in the main body case 4 of the dust detection unit 7 to the left side (the other short side) in the main body case 4 of the air cleaning unit 5 is defined as a length F. . The length from the right side (one short side) of the main body case 4 of the first substrate unit 9 to the left side (the other short side) of the main body case 4 of the second substrate unit 10 is a length G. It is defined as At this time, the length F and the length G are substantially the same. Note that “substantially the same” means that the length G is a length between 80% and 120% with respect to the length F.
　これにより、本体ケース４における左右方向（長辺方向）の長さが、それぞれ実質的に同じであるので、本体ケース４内にできる無駄な空間を抑制できる。 Thereby, since the length in the left-right direction (long side direction) in the main body case 4 is substantially the same, useless space formed in the main body case 4 can be suppressed.
　また、実施の形態１における車両用空気清浄機１において、第１の基板部９の本体ケース４における左右方向（長辺方向）の長さＨは、第２の基板部１０の本体ケース４における左右方向（長辺方向）の長さＩより長いことを特徴とするものである。空気清浄部５の右側（一方の短辺側）には、粉塵検知部７を備えている。送風部６の右側（一方の短辺側）には、第１の基板部９を備え、送風部６の左側（他方の短辺側）には、第２の基板部１０を備えている。ここで、送風部６の右側（一方の短辺側）の第１の基板部９の本体ケース４における左右方向（長辺方向）の長さＨは、送風部６の左側（他方の短辺側）の第２の基板部１０の本体ケース４における左右方向（長辺方向）の長さＩより長い。 In the vehicle air cleaner 1 according to the first embodiment, the length H in the left-right direction (long side direction) of the main body case 4 of the first substrate unit 9 is the same as that of the main body case 4 of the second substrate unit 10. It is longer than the length I in the left-right direction (long side direction). A dust detection unit 7 is provided on the right side (one short side) of the air cleaning unit 5. A first substrate unit 9 is provided on the right side (one short side) of the blower 6, and a second substrate unit 10 is provided on the left side (the other short side) of the blower 6. Here, the length H in the left-right direction (long side direction) in the main body case 4 of the first substrate unit 9 on the right side (one short side) of the blower unit 6 is the left side (the other short side) of the blower unit 6. Side) of the second substrate part 10 in the main body case 4 is longer than the length I in the left-right direction (long side direction).
　これにより、第１の基板部の長さＨが、第２の基板部１０の長さＩより短い場合に比べ、送風部６の中心Ｅ（吸気口の中心）と、空気清浄部５の中心Ｄとの距離が縮まる。つまり、送風部６の中心Ｅから空気清浄部５の両端までの距離がＡ／２（同一）に近づくので、空気清浄部５の左右方向（長辺方向）における風量が均一に近づき、空気清浄部５全体でより均一に空気中の埃等を捕集できる。 Thereby, compared with the case where the length H of the 1st substrate part is shorter than the length I of the 2nd substrate part 10, the center E (center of an air inlet) of the ventilation part 6 and the center of the air purifying part 5 are compared. The distance from D decreases. That is, since the distance from the center E of the air blowing unit 6 to both ends of the air cleaning unit 5 approaches A / 2 (same), the air volume in the left-right direction (long side direction) of the air cleaning unit 5 approaches uniformly, and the air cleaning The entire portion 5 can collect dust and the like in the air more uniformly.
　また、本体ケース４は、運転席より後方で車内の天井３面の左右方向における中心線上に装着されている。ここで、本体ケース４における前側（他方の長辺側）が車における前方向となり、本体ケース４における右側（一方の短辺側）が運転席側となる。本体ケース４は、天井３面に固定され、本体ケース４の上面である上本体ケース２２と、上本体ケース２２に装着される本体ケース４の下面である下本体ケース２３とを有している。下本体ケース２３は、第１の下本体ケース２３Ａと第２の下本体ケース２３Ｂを備えている。第１の基板部９は、制御基板部分１９と操作用基板部分２０を有している。操作用基板部分２０は、操作用基板２５と、操作用基板２５に設けた複数のスイッチ２１を備えている。第１の下本体ケース２３Ａは、スイッチ２１が貫通する複数の孔２７を有する。 Also, the main body case 4 is mounted on the center line in the left-right direction of the three ceiling surfaces in the vehicle behind the driver's seat. Here, the front side (the other long side) in the main body case 4 is the front direction in the vehicle, and the right side (one short side) in the main body case 4 is the driver seat side. The main body case 4 is fixed to the ceiling 3 surface, and has an upper main body case 22 that is an upper surface of the main body case 4 and a lower main body case 23 that is a lower surface of the main body case 4 attached to the upper main body case 22. . The lower body case 23 includes a first lower body case 23A and a second lower body case 23B. The first substrate portion 9 has a control substrate portion 19 and an operation substrate portion 20. The operation substrate portion 20 includes an operation substrate 25 and a plurality of switches 21 provided on the operation substrate 25. The first lower main body case 23A has a plurality of holes 27 through which the switch 21 passes.
　これにより、第１の基板部９は、本体ケース４における前側（他方の長辺側）で、かつ右側（一方の短辺側）に配置されている。つまり、本体ケース４における右側（一方の短辺側）、運転席側にスイッチ２１を備えている。これにより、スイッチ２１は、運転席より後方ではあるが、運転席からスイッチ２１までの距離が近くなるので、本体ケース４における左側（他方の短辺側）に配置されている場合に比べて、運転席からのスイッチ操作が容易になる。 Thereby, the first substrate portion 9 is arranged on the front side (the other long side) and the right side (the one short side) of the main body case 4. That is, the switch 21 is provided on the right side (one short side) of the main body case 4 and the driver seat side. Thereby, although the switch 21 is behind the driver's seat, since the distance from the driver's seat to the switch 21 is closer, compared to the case where the switch 21 is disposed on the left side (the other short side) in the main body case 4, Switch operation from the driver's seat becomes easy.
　また、表示部８は、下本体ケース２３における左側（他方の短辺側）寄り、つまり運転席より後方で助手席側に配置されている。 Further, the display unit 8 is arranged on the passenger seat side near the left side (the other short side) in the lower body case 23, that is, behind the driver seat.
　これにより、運転席から後方を振り返って表示部８を確認する場合に、表示部が運転席より後方で運転席側に配置されている場合に比べて、振り返る角度が小さいので、運転席からの表示部８の確認が容易になる。 As a result, when looking back from the driver's seat and confirming the display unit 8, the turning angle is smaller than when the display unit is arranged behind the driver's seat and on the driver's seat side. The display unit 8 can be easily confirmed.
　なお、ここでは本体ケース４における右側（一方の短辺側）が運転席側となる場合、つまり、左側ハンドルの場合について説明した。本体ケース４における左側（他方の短辺側）が運転席側となる場合、つまり右側ハンドルの場合は、上記構成を全て左右反対とすれば同様の効果を得られる。 In addition, here, the case where the right side (one short side) in the main body case 4 is the driver's seat side, that is, the case of the left-side handle has been described. In the case where the left side (the other short side) in the main body case 4 is the driver's seat side, that is, in the case of the right-side handle, the same effect can be obtained if all the above configurations are reversed.
　図７は、実施の形態１における車両用空気清浄機の粉塵検知部を示す斜視図である。図７に示すように、粉塵検知部７は、箱形状の検知ケース２９と、検知ケース２９内に設けられた検知センサー（図示せず）とを有している。検知ケース２９は、検知用吸込口３１と、検知用吹出口３２とを備えている。検知ケース２９内には、検知用吸込口３１と検知用吹出口３２とを連通する水平方向に延びた検知用風路３３が形成されている。このように、箱形状の検知ケース２９内に検知用風路３３が水平方向に延びているので、検知ケース２９を左右、前後方向の寸法に比べて、上下方向の寸法が小さい略箱形状にでき、装置の薄型化が可能となる。 FIG. 7 is a perspective view showing a dust detection unit of the vehicle air cleaner according to the first embodiment. As shown in FIG. 7, the dust detection unit 7 includes a box-shaped detection case 29 and a detection sensor (not shown) provided in the detection case 29. The detection case 29 includes a detection inlet 31 and a detection outlet 32. In the detection case 29, a detection air passage 33 extending in the horizontal direction that communicates the detection inlet 31 and the detection outlet 32 is formed. As described above, since the detection air passage 33 extends in the horizontal direction inside the box-shaped detection case 29, the detection case 29 has a substantially box-like shape whose vertical dimension is smaller than the horizontal and front-rear dimensions. This makes it possible to reduce the thickness of the device.
　（実施の形態２）
　次に実施の形態２における車両用空気清浄機について説明する。 (Embodiment 2)
Next, the air cleaner for vehicles in Embodiment 2 is demonstrated.
　従来、この種の車両用空気清浄機は、清浄吹出口と清浄吸込口とを有する箱形状の本体ケース内に、清浄吹出口と清浄吸込口とを連通する清浄送風路が形成され、清浄送風路に空気清浄部と送風部とを備えている。本体ケースは、車内天井面に取り付けられ、本体ケースの上面である上本体ケースと、上本体ケースに装着され、本体ケースの下面となる第１の下本体ケースと第２の下本体ケースとを備えている。上本体ケースには送風部が固定され、第２の下本体ケースには空気清浄部が装着されている。第２の下本体ケースは、垂直断面形状がＵ字形状で、第２の下本体ケースの両側面の上端によって、上本体ケースを挟むように装着されていた。そして第２の下本体ケースを下方向へ移動させることにより、第２の下本体ケースを本体ケースから外す構成であるものが知られている（例えば、特許文献２参照）。 Conventionally, in this type of vehicle air cleaner, a clean air passage that connects the clean air outlet and the clean air inlet is formed in a box-shaped main body case having a clean air outlet and a clean air inlet. The road is provided with an air purifier and a blower. The main body case is attached to a ceiling surface in the vehicle, and includes an upper main body case which is an upper surface of the main body case, a first lower main body case and a second lower main body case which are attached to the upper main body case and serve as the lower surface of the main body case. I have. A blower is fixed to the upper main body case, and an air purifier is attached to the second lower main body case. The second lower main body case has a U-shaped vertical cross-sectional shape, and is mounted so that the upper main body case is sandwiched between upper ends of both side surfaces of the second lower main body case. And what is the structure which removes a 2nd lower main body case from a main body case by moving a 2nd lower main body case to a downward direction is known (for example, refer patent document 2).
　従来より、車室内の天井に取り付けるタイプである車両用空気清浄機では、空気清浄部のメンテナンス性の更なる向上が望まれている。 Conventionally, in a vehicle air cleaner that is a type that is mounted on a ceiling in a vehicle compartment, further improvement in maintainability of the air purifier has been desired.
　空気清浄部を取り外す場合には、空気清浄部に直接触ることなく取り外せるように、空気清浄部が第２の下本体ケースに取り付けられており、この第２の下本体ケースを、上本体ケースから外すと、空気清浄部も同時に取り外せる構成であった。 When removing the air cleaning part, the air cleaning part is attached to the second lower body case so that it can be removed without directly contacting the air cleaning part. When it was removed, the air purifier could be removed at the same time.
　しかしながら、第２の下本体ケースは、垂直断面形状がＵ字形状で、第２の下本体ケースの両側面の上端によって、上本体ケースを挟むように装着され、落下方向である下方向へ移動させることにより上本体ケースから第２の下本体ケースを外す構成であった。そのために、外すときに片側の側面に力を入れすぎ、片側の側面だけが下げると、第２の下本体ケースが大きく傾いたり、第２の下本体ケースを落すことで、空気清浄部で捕集した粉塵が、飛び散る場合があった。 However, the second lower body case has a U-shaped vertical cross section, and is mounted so that the upper body case is sandwiched by the upper ends of both side surfaces of the second lower body case, and moves downward in the falling direction. By doing so, the second lower body case is removed from the upper body case. For this reason, if too much force is applied to one side when removing, and only one side is lowered, the second lower body case is greatly inclined or the second lower body case is dropped, so that the air purifier captures it. The collected dust may be scattered.
　そこで実施の形態２では、空気清浄部を取り外す場合に、空気清浄部が大きく傾いたり、第２の下本体ケースを落すことで、空気清浄部で捕集した粉塵が飛び散ることを抑制する車両用空気清浄機を提供することを目的とする。 Therefore, in the second embodiment, when removing the air purifying unit, the air purifying unit is greatly inclined, or the second lower main body case is dropped to suppress the dust collected by the air purifying unit from being scattered. An object is to provide an air purifier.
　そして、この目的を達成するために、実施の形態２では、箱形状で、第１の吹出口と第１の吸込口とを有し、車両天井面に取り付けられる本体ケースと、上記本体ケース内に形成された、上記第１の吹出口と上記第１の吸込口とを連通する第１の送風路と、上記第１の送風路に設けた、空気清浄部および送風部と、を備え、上記本体ケースは、上記本体ケースの上面を構成する上本体ケースと、上記上本体ケースに取り付けられ上記本体ケースの下面を構成する第１の下本体ケースおよび第２の下本体ケースと、を備え、上記上本体ケースには上記送風部が固定され、上記第２の下本体ケースには上記空気清浄部が装着され、上記第２の下本体ケースは、水平方向へ移動させることにより上記上本体ケースに対して着脱される構成であることを特徴としたものである。 And in order to achieve this objective, in Embodiment 2, it has a box shape, has a 1st blower outlet and a 1st inlet, and is attached to a vehicle ceiling surface. A first air passage that communicates the first air outlet and the first air inlet, and an air purifier and an air fan provided in the first air passage, The main body case includes an upper main body case constituting an upper surface of the main body case, and a first lower main body case and a second lower main body case which are attached to the upper main body case and constitute the lower surface of the main body case. The air blower is fixed to the upper body case, the air purifier is attached to the second lower body case, and the second lower body case is moved in the horizontal direction to move the upper body. The configuration is detachable from the case. Is obtained by it said.
　これにより、第２の下本体ケースを上本体ケースから取り外す時に、空気清浄部が大きく傾いたり、第２の下本体ケースを落してしまい、空気清浄部で捕集した粉塵が、飛び散ることを抑制できる車両用空気清浄機を提供することができる。 As a result, when removing the second lower main body case from the upper main body case, the air purifying part is greatly inclined or the second lower main body case is dropped, and the dust collected by the air purifying part is prevented from scattering. A vehicle air cleaner that can be provided can be provided.

The air blowing unit 6 is disposed between the first substrate unit 9 and the second substrate unit 10 and is disposed adjacent to both the first substrate unit 9 and the second substrate unit 10.
　続いて空気清浄部５の取り外し方について説明する。図１０は、実施の形態２における車両用空気清浄機において、上本体ケースから第２の下本体ケースを外した模式図である。図１０に示すように、空気清浄部５は、第２の下本体ケース２３Ｂの上面に着脱自在に装着されている。第２の下本体ケース２３Ｂは、上本体ケース２２に着脱自在に装着され、本体ケース４内における後側（一方の長辺側）へ移動させることにより上本体ケース２２から外れる構成である。 Next, how to remove the air cleaning unit 5 will be described. FIG. 10 is a schematic diagram in which the second lower main body case is removed from the upper main body case in the vehicle air cleaner according to the second embodiment. As shown in FIG. 10, the air purifier 5 is detachably mounted on the upper surface of the second lower main body case 23B. The second lower main body case 23 </ b> B is detachably attached to the upper main body case 22, and is configured to be detached from the upper main body case 22 by moving to the rear side (one long side) in the main body case 4.
　具体的には、第２の下本体ケース２３Ｂは、水平面を有する四角形の下板３４と、２枚の第１の側板３５と、第２の側板３６と、を備える。第１の側板３５は、下板３４における第２の下本体ケース２３Ｂの移動方向に沿った２つの辺からそれぞれ上方へ延びた２枚の側板をいう。第２の側板３６は、下板３４における第１の下本体ケース２３Ａとは反対側の辺から上方へ延びた側板をいう。 Specifically, the second lower body case 23 </ b> B includes a rectangular lower plate 34 having a horizontal plane, two first side plates 35, and a second side plate 36. The first side plate 35 refers to two side plates extending upward from two sides of the lower plate 34 along the moving direction of the second lower main body case 23B. The second side plate 36 is a side plate extending upward from the side of the lower plate 34 opposite to the first lower main body case 23A.
　第２の側板３６は、２枚の第１の側板３５と連結し、第１の吸込口１３である複数の開口３７を設け、第１の側板３５のそれぞれは、上端に内方へ延びた爪部３８を備えている。上本体ケース２２には、爪部３８のそれぞれが嵌る２つの水平方向に延びた水平溝部３９を設けている。この構成により、第２の下本体ケース２３Ｂは、水平方向への移動が可能となる。つまり、第２の下本体ケース２３Ｂを本体ケース４内における後側（一方の長辺側）へ移動させることにより、空気清浄部５に触れずに、上本体ケース２２から第２の下本体ケース２３Ｂと空気清浄部５とを外すことができる。 The second side plate 36 is connected to the two first side plates 35, and is provided with a plurality of openings 37 that are the first suction ports 13, and each of the first side plates 35 extends inward at the upper end. A claw portion 38 is provided. The upper main body case 22 is provided with two horizontal groove portions 39 extending in the horizontal direction in which the respective claw portions 38 are fitted. With this configuration, the second lower main body case 23B can be moved in the horizontal direction. That is, by moving the second lower main body case 23 </ b> B to the rear side (one long side) in the main body case 4, the second lower main body case 22 can be moved from the upper main body case 22 without touching the air cleaning unit 5. 23B and the air purifying part 5 can be removed.
　このように、第２の下本体ケース２３Ｂは、落下方向に対して直角方向となる水平方向へ移動させることにより上本体ケース２２から外れる構成である。よって、空気清浄部５を取り外す時に、空気清浄部５の傾きや第２の下本体ケース２３Ｂの落下などに起因する空気清浄部５からの粉塵の飛散を抑制できる車両用空気清浄機を提供することができる。 Thus, the second lower main body case 23B is configured to be detached from the upper main body case 22 by moving in the horizontal direction which is a direction perpendicular to the dropping direction. Therefore, when removing the air purification part 5, the air cleaner for vehicles which can suppress scattering of the dust from the air purification part 5 resulting from the inclination of the air purification part 5, the fall of the 2nd lower main body case 23B, etc. is provided. be able to.
　また、清浄吸込口である第１の吸込口１３は、第２の下本体ケース２３Ｂの第２の側板３６に設けた複数の開口３７である。空気清浄部５における風上側に、複数の開口３７である第１の吸込口１３を備えている。これにより、空気清浄部５を取り外す時に、空気清浄部５を傾けた場合にも、空気清浄部５における風上側に溜まった粉塵の塊が、複数の横長四角形状の開口３７を形成している格子３０によって、車内に落下するのを抑制できる。 Further, the first suction port 13 which is a clean suction port is a plurality of openings 37 provided in the second side plate 36 of the second lower main body case 23B. A first suction port 13 that is a plurality of openings 37 is provided on the windward side of the air cleaning unit 5. Thereby, when removing the air cleaning part 5, even when the air cleaning part 5 is inclined, the lump of dust accumulated on the windward side of the air cleaning part 5 forms a plurality of horizontally elongated openings 37. The lattice 30 can suppress falling into the vehicle.
　また、水平溝部３９の本体ケース４における後側先端には、下方へ傾斜した傾斜溝部４１を設けた。これにより、上本体ケース２２に第２の下本体ケース２３Ｂを取り付ける場合に、第２の下本体ケース２３Ｂを傾斜させて、爪部３８を傾斜溝部４１に挿入できるので、取り付け作業が容易になる。 Further, an inclined groove portion 41 inclined downward is provided at the rear end of the main body case 4 of the horizontal groove portion 39.
