以下、本実施形態を添付図面を用いて説明する。   Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

（実施の形態１）
図１から３に示すように、本実施形態の空気清浄装置は、吸気口１と排気口２を有する本体ケース３と、この本体ケース３内に設けた空気清浄手段４と、この空気清浄手段４の下流側に加湿手段５とを備えている。 (Embodiment 1)
As shown in FIGS. 1 to 3, the air purifying apparatus of the present embodiment includes a main body case 3 having an intake port 1 and an exhaust port 2, an air cleaning means 4 provided in the main body case 3, and the air cleaning means. Humidification means 5 is provided on the downstream side of 4.

吸気口１は、本体ケース３の両側面に設けた第１の吸気口１ａと、本体ケース３の前面下部に設けた第２の吸気口１ｂと、本体ケース３の前面上部に設けた第３の吸気口１ｃから形成され、排気口２は、本体ケース３の天面に設けている。   The intake port 1 includes a first intake port 1 a provided on both side surfaces of the main body case 3, a second intake port 1 b provided on the lower front surface of the main body case 3, and a third intake port provided on the upper front surface of the main body case 3. The exhaust port 2 is provided on the top surface of the main body case 3.

空気清浄手段４は縦長箱形状の空気清浄フィルター４ａで、濾材が蛇腹形状に折られたものであり、第１の吸気口１ａ、第２の吸気口１ｂ、および第３の吸気口１ｃの風路風下側で、前面化粧板７に対向する位置に設けられている。   The air purifying means 4 is a vertically long box-shaped air purifying filter 4a, in which the filter medium is folded in a bellows shape, and the air in the first air intake port 1a, the second air intake port 1b, and the third air intake port 1c. It is provided at a position facing the front decorative plate 7 on the downwind side of the road.

加湿手段５は、空気清浄手段４の風路風下側に設けられており、一定量の水が溜まった略椀形状の水槽５ａと、この水槽５ａの水に周縁部の一部が常に浸漬した円板状の加湿フィルター部５ｂと、この加湿フィルター部５ｂを固定する略円環形状の加湿フィルター枠部５ｃと、この加湿フィルター枠部５ｃを回転させる回転手段とから形成されている。   The humidifying means 5 is provided on the downwind side of the air path of the air purifying means 4, and a substantially bowl-shaped water tank 5a in which a certain amount of water is accumulated, and a part of the peripheral portion is always immersed in the water of the water tank 5a. It is formed of a disc-shaped humidifying filter portion 5b, a substantially annular humidifying filter frame portion 5c for fixing the humidifying filter portion 5b, and a rotating means for rotating the humidifying filter frame portion 5c.

このような構成における空気清浄および、加湿動作について説明する。   The air cleaning and humidification operation in such a configuration will be described.

水タンク５ｄより水槽５ａに常時一定の水位となるように水が供給され、この水に加湿手段の加湿フィルター部５ｂの一部が常時浸かった状態となる。ここで回転手段によって加湿フィルター枠部５ｃを回転させることで、加湿フィルター部５ｂが回転し、この加湿フィルター部５ｂに保持された水が、頂上付近で加湿フィルター部５ｂの中心方向に移動し、加湿フィルター部５ｂ全体を湿らせる。つまり回転手段により加湿フィルター枠部５ｃを回転させ続けることで加湿フィルター部５ｂは常時水を保持した状態に保たれる。   Water is supplied from the water tank 5d to the water tank 5a so that the water level is always constant, and a part of the humidifying filter portion 5b of the humidifying means is always immersed in this water. Here, by rotating the humidifying filter frame portion 5c by the rotating means, the humidifying filter portion 5b rotates, and the water held in the humidifying filter portion 5b moves toward the center of the humidifying filter portion 5b near the top, The entire humidifying filter part 5b is moistened. That is, by continuously rotating the humidifying filter frame 5c by the rotating means, the humidifying filter 5b is always kept in a state of holding water.

ここで、送風手段６を動かすことにより、第１の吸気口１ａ、第２の吸気口１ｂ、および第３の吸気口１ｃから本体ケース３内に空気が吸い込まれ、その後空気は本体ケース３内に備えられた空気清浄フィルター４ａと水を保持した状態の加湿フィルター部５ｂとを通過して加湿清浄空気となり、排気口２から室内に排出される。   Here, by moving the air blowing means 6, air is sucked into the main body case 3 from the first air inlet 1a, the second air inlet 1b, and the third air inlet 1c. Passes through the air purification filter 4a provided in the water and the humidifying filter portion 5b holding water, and becomes humidified clean air, and is exhausted from the exhaust port 2 into the room.

本実施形態における特徴は、前面化粧板７が最上点に移動した場合に、前面化粧板７に設けた風量調整部材８により第３の吸気口１ｃの開口面積を低減させ、第２の吸気口１ｂからの吸い込み風量を増加させる点にある。   The feature of this embodiment is that when the front decorative plate 7 moves to the highest point, the air volume adjusting member 8 provided on the front decorative plate 7 reduces the opening area of the third intake port 1c, and the second intake port The point is to increase the amount of air sucked from 1b.

具体的には、床上近傍の空気の吸い込み風量を更に増加させるために、本体ケース３の前面に所定の距離を有して設けた前面化粧板７を上方に移動させることにより、第２の吸気口１ｂの開口面積を拡大させるのであるが、前面化粧板７が最上点に移動した場合に、第１の吸気口１ａの開口面積は中開口状態、第２の吸気口１ｂの開口面積は大開口状態、さらに、第３の吸気口１ｃの開口面積は、前面化粧板７と空気清浄手段４との間に位置するように設けた風量調整部材８によって本体ケース３との通風路が塞がれることにより極小開口状態となるものである。   Specifically, in order to further increase the amount of air sucked in the vicinity of the floor, the front intake plate 7 provided at a predetermined distance on the front surface of the main body case 3 is moved upward to thereby generate the second intake air. The opening area of the mouth 1b is enlarged. When the front decorative plate 7 moves to the uppermost point, the opening area of the first air inlet 1a is in the middle opening state, and the opening area of the second air inlet 1b is large. The opening state and the opening area of the third air inlet 1c are such that the air flow path with the main body case 3 is blocked by the air volume adjusting member 8 provided so as to be positioned between the front decorative plate 7 and the air cleaning means 4. As a result, a minimum opening state is obtained.

このように、前面化粧板７が最上点に位置する場合、前面化粧板７に設けた風量調整部材８により、第３の吸気口１ｃの開口面積が極小化されることで、相対的に第２の吸気口１ｂから吸い込まれる風量が増大し、床上近傍の空気の吸い込み風量を更に増加させることができる。   Thus, when the front decorative plate 7 is located at the uppermost point, the opening area of the third intake port 1c is minimized by the air volume adjusting member 8 provided on the front decorative plate 7, so that the first The amount of air sucked from the second air inlet 1b increases, and the amount of air sucked near the floor can be further increased.

また、図４に示すように、前面化粧板７に設けた風量調整部材８の天面に、前面化粧板７の内側面を頂点に下り方向の傾斜面９を設けたものである。   Further, as shown in FIG. 4, a downwardly inclined surface 9 is provided on the top surface of the air volume adjusting member 8 provided on the front decorative plate 7 with the inner side surface of the front decorative plate 7 as a vertex.

このように、風量調整部材８の天面に傾斜面を設けることで、第３の吸気口１ｃを通過する吸い込み風によるホコリやゴミの付着を防ぐことができる。   In this way, by providing the inclined surface on the top surface of the air volume adjusting member 8, it is possible to prevent dust and dust from being attached due to the suction air passing through the third air inlet 1c.

また、図５に示すように、前面化粧板７に設けた風量調整部材８の一部に手掛かり形状１０を設けたものである。   Further, as shown in FIG. 5, a clue shape 10 is provided on a part of the air volume adjusting member 8 provided on the front decorative plate 7.

このように、風量調整部材８に手掛かり形状１０を設けることで、空気清浄手段４のお手入れ時に前面化粧板７を取り外して仮置きする際や、再度取り付ける際に、手掛かり形状１０を掴んで、容易に運搬することができる。   Thus, by providing the clue shape 10 on the air volume adjusting member 8, when the front decorative plate 7 is removed and temporarily placed at the time of cleaning the air cleaning means 4, or when reattaching, the clue shape 10 is grasped, It can be easily transported.
