そして、図6を参照して、保持部17について詳述すると、保持部17は、ルーバー枠14のルーバー開口13の縁部近傍に設けられた押圧部21、引掛け部22およびたわみ部23と、グリル部15に設けられた支持孔24とから構成され、保持している状態から押圧部21を指で押すことで、図7に示すように、たわみ部23が弾性変形することで、引掛け部22が支持孔24から脱却して保持が解除され、また、グリル部15を装着する場合は、グリル部15の一側部を指で押すことで、たわみ部23が弾性変形し、変形から復帰しようとする力によって、引掛け部22が支持孔24に引っ掛かって保持され、このようにして、グリル部15によってルーバー開口13を容易に開閉することができる。   Then, the holding part 17 will be described in detail with reference to FIG. 6. The holding part 17 includes a pressing part 21, a hooking part 22, and a bending part 23 provided in the vicinity of the edge part of the louver opening 13 of the louver frame 14. 7 and the support hole 24 provided in the grill portion 15, and by pressing the pressing portion 21 with a finger from the holding state, the bending portion 23 is elastically deformed as shown in FIG. The holding portion 22 is released from the support hole 24 to be released from the holding state. When the grill portion 15 is mounted, the flexible portion 23 is elastically deformed by pressing one side portion of the grill portion 15 with a finger. The hook 22 is hooked and held in the support hole 24 by the force to return from the above, and thus the louver opening 13 can be easily opened and closed by the grill 15.

また、図8および図9を参照して、回動支軸16について詳述すると、回動支軸16は、ルーバー枠14のルーバー開口13近傍に設けられた係合部25と、係合部25に対応するグリル部15の一側端部の位置に設けられ、係合部25に係脱自在に係止するフック形状の係止部26とからなり、係合部25と係止部26は、それぞれ複数個設けられ、複数個の係合部25あるいは係止部26は、グリル部15およびルーバー枠14の左右方向中心線Cから異なる距離の位置に配設されている。   8 and 9, the rotation support shaft 16 will be described in detail. The rotation support shaft 16 includes an engagement portion 25 provided near the louver opening 13 of the louver frame 14, and an engagement portion. 25, a hook-shaped locking portion 26 that is provided at a position on one side end portion of the grill portion 15 corresponding to 25 and is detachably locked to the engaging portion 25, and includes the engaging portion 25 and the locking portion 26. The plurality of engaging portions 25 or the locking portions 26 are disposed at different distances from the center line C in the left-right direction of the grill portion 15 and the louver frame 14.

また、図10に示すように、ルーバー枠14のルーバーばね保持部18は、平面視でルーバー開口13上に位置しないように、ルーバー開口13の縁部に、ルーバー枠14と一体に形成され、ルーバー開口13の縁部からルーバー枠14側に水平に突出した水平部27と、水平部27先端から垂直に形成された垂直部28とからなり、垂直部28の下端部とルーバー枠14の裏面との間に開口したルーバーばね19の挿入開口29を形成している。挿入開口29は、ルーバーばね19の線径より狭く形成され、ルーバーばね19を挿入開口29から挿入するときは、水平部27と垂直部28を弾性変形させて挿入し、挿入されたルーバーばね19は外れにくくなる。   Further, as shown in FIG. 10, the louver spring holding portion 18 of the louver frame 14 is formed integrally with the louver frame 14 at the edge of the louver opening 13 so as not to be positioned on the louver opening 13 in plan view. The louver opening 13 includes a horizontal portion 27 that protrudes horizontally from the edge of the louver opening 14 toward the louver frame 14, and a vertical portion 28 that is vertically formed from the tip of the horizontal portion 27. The insertion opening 29 of the louver spring 19 opened between the two is formed. The insertion opening 29 is formed narrower than the wire diameter of the louver spring 19. When the louver spring 19 is inserted from the insertion opening 29, the horizontal portion 27 and the vertical portion 28 are elastically deformed and inserted, and the inserted louver spring 19 is inserted. Is hard to come off.

また、図示していないが、グリル部15の裏面側に、排気中の塵埃等を捕集するフィルターを着脱自在に装着している。   Although not shown, a filter that collects dust and the like in the exhaust is detachably attached to the back side of the grill portion 15.

そして、グリル部15について、格子状のものを図示してきたが、本実施の形態1の天井埋込形換気扇では、図11に示す一方向の桟を有したグリル部15Aも備えている。なお、この2種類だけでなく、たとえばグリル部の外周部に通風口を形成するもの等を備えることもできる。   And although the lattice-shaped thing was shown about the grill part 15, the ceiling-embedded ventilation fan of this Embodiment 1 is also provided with the grill part 15A which has the unidirectional crosspiece shown in FIG. In addition to these two types, for example, a device that forms a vent hole on the outer peripheral portion of the grill portion can be provided.

すなわち、ルーバー12全体を取り替えることなく、グリル部15だけを取り替えることで、天井埋込形換気扇の設置環境から求められるデザイン・換気機能等に、容易かつ安価に対応できる。   That is, by replacing only the grill portion 15 without replacing the entire louver 12, it is possible to easily and inexpensively meet the design and ventilation functions required from the installation environment of the ceiling-embedded ventilation fan.

上記構成において、長時間の運転により天井埋込形換気扇の内部に室内の埃等が付着してきて掃除するときには、グリル部15を保持部17から保持を外して回動すると、裏面に装着したフィルターが現れるので、まず、ルーバー12全体を取り外すことなくフィルターのみを外して清掃することができ、次に、フィルターを通過した埃等が付着した遠心送風羽根8の掃除に対して、天井裏という高い位置に設けられた暗く狭いフレーム4の空間内で、オリフィス11をケーシング7から工具を使用せずに取り外しでき、オリフィス11を取り外すことによって、ケーシング7の下面に遠心送風羽根8を取り出すことが可能なケーシング開口5を形成できる。そして、ルーバー12のルーバー開口13は、グリル部15を回動して開放されているので、ルーバー12を取り外すことなくルーバー開口13から遠心送風羽根8を室内側へ取り出すことができる。   In the above configuration, when cleaning is performed when dust or the like adheres to the interior of a ceiling-embedded ventilation fan in a long-time operation, the filter attached to the back surface is removed by rotating the grill portion 15 from the holding portion 17. First, the filter can be removed and cleaned without removing the entire louver 12, and then the ceiling back is high for cleaning the centrifugal blower blade 8 to which dust or the like that has passed through the filter adheres. The orifice 11 can be removed from the casing 7 without using a tool in the space of the dark narrow frame 4 provided at the position, and the centrifugal blower blade 8 can be taken out from the lower surface of the casing 7 by removing the orifice 11. A simple casing opening 5 can be formed. Since the louver opening 13 of the louver 12 is opened by rotating the grill portion 15, the centrifugal blower blade 8 can be taken out from the louver opening 13 to the indoor side without removing the louver 12.

このように、工具を使用せずにオリフィス11を取り外して形成されるケーシング開口5と、小さな指の押圧力でグリル部15の保持を外すことにより形成されるルーバー開口13とから、遠心送風羽根8を室内側に取り出して掃除をすることができ、掃除性の向上した天井埋込形換気扇を提供することができることとなる。   Thus, the centrifugal blower blade is formed from the casing opening 5 formed by removing the orifice 11 without using a tool and the louver opening 13 formed by removing the holding of the grill portion 15 with a small finger pressing force. 8 can be taken out indoors and cleaned, and a ceiling-embedded ventilation fan with improved cleanability can be provided.

そして、グリル部15もルーバー枠14の係合部25から外して掃除し、その後、ルーバー枠14に係合する際に、誤って裏表逆に取り付けようとしても、係合部25と係止部26が左右方向にずれた位置となって、取り付け固定できないこととなり、グリル部15の裏表逆取り付けを防止できる。   Then, the grill portion 15 is also removed from the engaging portion 25 of the louver frame 14 and cleaned, and then when engaging with the louver frame 14, the engaging portion 25 and the engaging portion are mistakenly attached. 26 becomes a position shifted in the left-right direction, so that the attachment and fixing cannot be performed, and the reverse mounting of the grill portion 15 can be prevented.

また、ルーバーばね保持部18が、平面視でルーバー開口13上に位置しない、すなわち、ルーバー開口13よりも外側に配置されているため、排気する空気の流路を妨げてしまうことがなく、それによる風量低下や騒音増加がなく、かつ、内部のオリフィス11や遠心送風羽根8をルーバー開口13から取り出す際の作業の邪魔にもならない。   Further, since the louver spring holding portion 18 is not located on the louver opening 13 in a plan view, that is, disposed outside the louver opening 13, the louver spring holding portion 18 does not disturb the flow path of the exhausted air. Therefore, there is no decrease in the air volume or increase in noise due to the above, and it does not interfere with the operation when the internal orifice 11 and the centrifugal blower blade 8 are taken out from the louver opening 13.

また、ルーバーばね保持部18は、挿入開口29がルーバーばね19の線材径よりも狭いため、ルーバーばね19は一旦装着されれば、ルーバー12を取り付ける際のルーバーばね19の張力等によってルーバーばね保持部18から抜けてしまうことがなく、さらに、挿入開口29がルーバー開口13の外方に向けて開口されているため、ルーバーばね19の張力によるルーバー開口13縁部の変形は微小なものとなる。   Further, since the louver spring holding portion 18 has an insertion opening 29 narrower than the wire rod diameter of the louver spring 19, once the louver spring 19 is mounted, the louver spring is held by the tension of the louver spring 19 when the louver 12 is attached. Since the insertion opening 29 is opened toward the outside of the louver opening 13, the deformation of the edge of the louver opening 13 due to the tension of the louver spring 19 is minute. .

また、ルーバー開口13を設けていても、ルーバー12を空気中に含まれる油などに対して強いPP樹脂製にすることで、ルーバー12の強度を維持することができる。   Moreover, even if the louver opening 13 is provided, the strength of the louver 12 can be maintained by making the louver 12 made of PP resin that is strong against oil contained in the air.

本発明は、遠心送風羽根の掃除を行うときの部品の分解性、組立性、作業性が良く、遠心送風羽根の掃除を要する換気装置や遠心送風機、空気調和機に有用である。   INDUSTRIAL APPLICABILITY The present invention has good parts disassembly, assembly, and workability when cleaning the centrifugal blower blade, and is useful for a ventilation device, a centrifugal blower, and an air conditioner that require cleaning of the centrifugal blower blade.
