Description
本發明是關於一種浴室用取暖換氣扇,特別是關於一種浴室用取暖換氣扇的風路切換板的固定結構。The present invention relates to a heating ventilating fan for a bathroom, and more particularly to a fixing structure of a ventilating switchboard for a heating ventilating fan for a bathroom.
如圖1A、1B所示,為一種習知的浴室用取暖換氣扇100,包括:框架110、扇葉120、馬達130、加熱裝置140以及風路切換板200。As shown in FIGS. 1A and 1B, a conventional heating ventilating fan 100 for a bathroom includes a frame 110, a blade 120, a motor 130, a heating device 140, and a wind circuit switching plate 200.
該風路切換板200的兩端設有突起220,該突起220為空心結構,在取暖換氣扇100的風路壁300上設有容置並卡合風路切換板200兩端突起220的開口310。該開口310的外側與外置的步進電機700的轉軸710相嚙合,由轉軸710轉動帶動風路切換板200轉動,從而實現取暖換氣扇的取暖、換氣、和乾燥功能。A protrusion 220 is disposed at both ends of the air passage switching plate 200. The protrusion 220 is a hollow structure. The air passage wall 300 of the heating ventilation fan 100 is provided with an opening 310 for accommodating and engaging the protrusions 220 at both ends of the air passage switching plate 200. . The outer side of the opening 310 is engaged with the rotating shaft 710 of the external stepping motor 700, and the rotation of the rotating shaft 710 drives the air passage switching plate 200 to rotate, thereby realizing the heating, ventilation, and drying functions of the heating ventilation fan.
在安裝時,先用力彎曲風路切換板200,使風路切換板200兩端向中間彎曲變形,使其兩端的突起220卡入風路壁300上的開口310內,然後不再施加壓力,使其恢復平直的狀態,從而將風路切換板200固定在風路壁300上。但在安裝過程中,可能會存在風路切換板200無法完全恢復平直的狀態,或者隨著使用時間的增加,風路切換板200會有逐漸變彎曲的現象,因此會存在風路切換板200在轉動過程中掉落的可能性。During installation, the air passage switching plate 200 is first bent, and the ends of the air passage switching plate 200 are bent and deformed in the middle, so that the protrusions 220 at both ends are engaged in the opening 310 on the air passage wall 300, and then no pressure is applied. It is returned to a flat state, thereby fixing the air passage switching plate 200 to the air passage wall 300. However, during the installation process, there may be a state in which the air passage switching plate 200 cannot be completely restored to the straight state, or the air passage switching plate 200 may gradually become curved as the use time increases, so there is a wind path switching plate. The possibility of 200 falling during the rotation.
為防止風路切換板200在轉動過程中掉落,需要在風路切換板200內安裝有支撐軸210。支撐軸210兩軸端211的斷面直徑小於支撐軸210軸體212的斷面直徑,兩軸端211與軸體212之間形成段差。段差面213抵靠在在風路切換板200的兩端內側上。安裝時,先用力彎曲支撐軸210,使支撐軸210兩端向中間彎曲變形,將支撐軸210兩軸端211分別卡入空心結構的風路切換板200的突起220內,然後不再施加壓力,使其恢復平直的狀態。此時透過段差面213,該支撐軸210向兩端伸展施加壓力在風路切換板200的內側面上,從而保持風路切換板200的不變形。In order to prevent the air passage switching plate 200 from falling during the rotation, it is necessary to mount the support shaft 210 in the air passage switching plate 200. The cross-sectional diameter of the two shaft ends 211 of the support shaft 210 is smaller than the cross-sectional diameter of the shaft body 212 of the support shaft 210, and a step is formed between the two shaft ends 211 and the shaft body 212. The step faces 213 abut against the inner sides of both ends of the air passage switching plate 200. During installation, the support shaft 210 is bent first, and the two ends of the support shaft 210 are bent and deformed in the middle, and the two shaft ends 211 of the support shaft 210 are respectively inserted into the protrusions 220 of the air passage switching plate 200 of the hollow structure, and then no pressure is applied. To restore it to a straight state. At this time, the support shaft 210 is applied to the inner side surface of the air passage switching plate 200 through the step surface 213 so as to maintain the air passage switching plate 200 without deformation.
由於支撐軸210需要透過外力使其軸向變形,使其軸向的尺寸減小後再固定。裝配時,比較困難,容易造成支撐軸210兩軸端211損壞。而且,當支撐軸210整體被彎曲後,有時也會存在不能從彎曲變形後狀態完全恢復過來的可能性,從而導致不能實現其支撐功能的問題。Since the support shaft 210 needs to be axially deformed by an external force, the axial dimension is reduced and then fixed. When assembling, it is difficult to easily damage the two shaft ends 211 of the support shaft 210. Further, when the entire support shaft 210 is bent, there is a possibility that the state cannot be completely recovered from the state after the bending deformation, resulting in a problem that the supporting function cannot be realized.

如圖2所示,為本發明的第一實施例示意圖。一種取暖換氣扇100的風路切換板200的固定結構,包括風路切換板200以及風路切換板支撐結構400。2 is a schematic view of a first embodiment of the present invention. A fixing structure of the air passage switching plate 200 of the heating ventilating fan 100 includes an air path switching plate 200 and a wind path switching plate supporting structure 400.
風路切換板200向其兩端外側突出設置圓環狀的空心轉軸230、240,與空心轉軸230、240相對的換氣扇內的風路壁300上設有轉軸支撐座320、330,風路切換板200透過空心轉軸230、240安裝在轉軸支撐座320、330內。The air passage switching plate 200 is provided with annular hollow rotating shafts 230 and 240 protruding from the outer ends of the air passage switching plate 200. The air passage wall 300 in the ventilating fan opposite to the hollow rotating shafts 230 and 240 is provided with the rotating shaft supporting seats 320 and 330, and the air passage is switched. The plate 200 is mounted in the spindle support seats 320, 330 through the hollow shafts 230, 240.
風路切換板支撐結構400包括支撐軸500和與該支撐軸同軸的連接件600。The air circuit switchboard support structure 400 includes a support shaft 500 and a connector 600 coaxial with the support shaft.
該支撐軸500的一端510設有凸軸511,凸軸511的根部設有凸緣形狀的定位塊512。凸軸511固定於風路切換板200的一端231空心轉軸230內,定位塊512可以限定支撐軸500的凸軸511卡入空心轉軸230內的長度。支撐軸500的另一端520設有環狀帶簷的凹槽521,該凹槽521抵靠在風路切換板200的另一端232的內側面上。One end 510 of the support shaft 500 is provided with a convex shaft 511, and a root portion of the convex shaft 511 is provided with a flange-shaped positioning block 512. The protruding shaft 511 is fixed in the hollow shaft 230 of one end 231 of the air passage switching plate 200. The positioning block 512 can define a length in which the protruding shaft 511 of the supporting shaft 500 is caught in the hollow rotating shaft 230. The other end 520 of the support shaft 500 is provided with an annular band-shaped recess 521 that abuts against the inner side of the other end 232 of the air passage switching plate 200.
連接件600從風路的外側插入並穿出空心轉軸240,前端的軸610卡入支撐軸500的凹槽521內。連接件600的後端為連接軸620,該連接軸620位於空心轉軸240中。即,連接件600位於上述支撐軸500的延長處。The connecting member 600 is inserted from the outside of the air passage and passes through the hollow rotating shaft 240, and the shaft 610 at the front end is caught in the recess 521 of the supporting shaft 500. The rear end of the connecting member 600 is a connecting shaft 620 which is located in the hollow rotating shaft 240. That is, the connecting member 600 is located at an extension of the above-described support shaft 500.
由此,安裝時,首先將風路切換板200透過空心轉軸230安裝在轉軸支撐座320內,然後將支撐軸500的凸軸511固定於風路切換板200一端231的空心轉軸230內,然後將支撐軸500的凹槽521抵靠在風路切換板200的另一端232的內側面上,並對準風路切換板200該另一端232的空心轉軸240,然後透過從風路的外側將連接件600的前端的軸610插入支撐軸500的凹槽521內,從而固定風路切換板200。這樣支撐軸500從定位塊512到凹槽521端面之間的長度就是固定的,從而使風路切換板200的兩端的空心轉軸230、240之間的間隔得以保持不變,達到不小於規定的間隔的效果。也就是說,當風路切換板200變形時,透過支撐軸500在空心轉軸230、240之間的支撐作用,可以確保風路切換板200兩端之間規定的間隔。Therefore, in the installation, the air passage switching plate 200 is first installed in the rotating shaft support base 320 through the hollow rotating shaft 230, and then the protruding shaft 511 of the supporting shaft 500 is fixed in the hollow rotating shaft 230 of the one end 231 of the air passage switching plate 200, and then The groove 521 of the support shaft 500 abuts against the inner side surface of the other end 232 of the air passage switching plate 200, and is aligned with the hollow shaft 240 of the other end 232 of the air passage switching plate 200, and then passes through the outer side of the air passage. The shaft 610 of the front end of the connecting member 600 is inserted into the recess 521 of the support shaft 500, thereby fixing the air passage switching plate 200. Thus, the length of the support shaft 500 from the positioning block 512 to the end surface of the recess 521 is fixed, so that the interval between the hollow rotating shafts 230, 240 at both ends of the air passage switching plate 200 is kept constant, and is not less than the prescribed value. The effect of the interval. That is, when the air passage switching plate 200 is deformed, a predetermined interval between the both ends of the air passage switching plate 200 can be ensured by the support action of the support shaft 500 between the hollow rotating shafts 230, 240.
再將連接件600後端的連接軸620延伸到空心轉軸240的外側,位於風路壁300之外。連接件600後端的連接軸620位於空心轉軸240內形成扁狀,即在圓形的斷面形狀有直線部,空心轉軸240也形成中空的扁狀,即也形成直線部,由此連接件600後端的連接軸620和空心轉軸240相卡合。由此,透過步進電機700帶動連接件600旋轉而驅動風路切換板200轉動。The connecting shaft 620 at the rear end of the connecting member 600 is extended to the outside of the hollow rotating shaft 240, outside the air passage wall 300. The connecting shaft 620 at the rear end of the connecting member 600 is formed in a flat shape in the hollow rotating shaft 240, that is, has a straight portion in a circular cross-sectional shape, and the hollow rotating shaft 240 also forms a hollow flat shape, that is, a straight portion is also formed, whereby the connecting member 600 is formed. The connecting shaft 620 of the rear end and the hollow rotating shaft 240 are engaged. Thereby, the stepping motor 700 drives the connecting member 600 to rotate to drive the air passage switching plate 200 to rotate.
即在本實施例中,支撐軸500和連接件600取代了現有技術中的支撐軸210,在無需彎曲變形支撐軸500的情況下,透過支撐軸500自身的剛性,確保了風路切換板200的不變形,避免了風路切換板200在轉動過程中掉落的可能性。That is, in the present embodiment, the support shaft 500 and the connecting member 600 replace the support shaft 210 of the prior art, and the wind passage switching plate 200 is ensured through the rigidity of the support shaft 500 itself without bending the deformation support shaft 500. The deformation is not prevented, and the possibility that the air passage switching plate 200 is dropped during the rotation is avoided.
如圖3所示,為本發明的第二實施例示意圖。在本實施例中,與第一實施例的不同之處在於,連接件600與外置的步進電機700的轉軸710為一體。空心轉軸240的外側直接與外置的步進電機700的轉軸710相嚙合,即相當於在步進電機700上設置可直接卡入上述支撐軸500的凹槽521中的凸筋720。3 is a schematic view of a second embodiment of the present invention. In the present embodiment, the difference from the first embodiment is that the connecting member 600 is integral with the rotating shaft 710 of the external stepping motor 700. The outer side of the hollow rotating shaft 240 directly meshes with the rotating shaft 710 of the external stepping motor 700, that is, the rib 720 is provided on the stepping motor 700 to be directly inserted into the recess 521 of the support shaft 500.
安裝時,首先將風路切換板200透過空心轉軸230安裝在轉軸支撐座320內,然後將支撐軸500的凸軸511固定於風路切換板200一端231的空心轉軸230內,然後將支撐軸500的凹槽521抵靠在風路切換板200的另一端232的內側面上,並對準風路切換板200該另一端232的空心轉軸240,最後將步進電機700上設置的凸筋720插入支撐軸500的凹槽521內,從而將風路切換板200固定。During installation, the air passage switching plate 200 is first installed in the shaft support base 320 through the hollow shaft 230, and then the convex shaft 511 of the support shaft 500 is fixed in the hollow shaft 230 of the one end 231 of the air passage switching plate 200, and then the support shaft is supported. The groove 521 of the 500 abuts against the inner side of the other end 232 of the air passage switching plate 200, and is aligned with the hollow shaft 240 of the other end 232 of the air passage switching plate 200, and finally the rib provided on the stepping motor 700. The 720 is inserted into the recess 521 of the support shaft 500 to fix the air passage switching plate 200.
