「整體構成」 圖1表示一實施形態之空氣清淨裝置之外觀。空氣清淨裝置10整體具有四角柱狀之形狀。本體殼體12覆蓋側面及上表面之周邊部分。"Overall Composition" Fig. 1 shows an appearance of an air cleaning device according to an embodiment. The air cleaning device 10 has a rectangular column shape as a whole. The body casing 12 covers the peripheral portions of the side and upper surfaces.

於本體殼體12之前表面下部形成有前表面吸氣開口14。如下文所述般，該前表面吸氣開口14係截面四角形之隧道狀之吸氣通路16的前表面之開口，吸氣通路16貫通至背面，於背面側（後方）形成有背面之背面吸氣開口30（參照圖2）。A front surface suction opening 14 is formed in the lower portion of the front surface of the body casing 12. As described below, the front surface suction opening 14 is an opening of the front surface of the tunnel-shaped suction passage 16 with a rectangular cross section. The suction passage 16 penetrates to the back, and a back suction is formed on the back side (back). Air opening 30 (refer to FIG. 2).

再者，於本體殼體12之左右側面之縱向之中間部形成有供使用者用手提起之扶手用之凹部22（圖1中僅顯示右側面）。又，於本體殼體12之上表面之前表面側角部設置有複數個操作用之開關按鈕24。Furthermore, a concave portion 22 (only the right side is shown in FIG. 1) for the handrail for the user to lift up is formed in the middle portion in the longitudinal direction of the left and right side surfaces of the body casing 12. In addition, a plurality of operation switch buttons 24 are provided at the corners of the front surface side of the upper surface of the main body case 12.

圖2、3係表示空氣清淨裝置之內部構造之圖，圖2（a）為俯視圖，（b）為於（a）中通過一點鏈線（前後方向）之面處切斷之情形時之前視圖，（c）、（d）為於（a）中通過一點鏈線（前後方向）之面處切斷之情形時之立體圖，圖3（a）為俯視圖，（b）為於（a）中通過一點鏈線（左右方向）之面處切斷之情形時之前視圖，（c）、（d）為於（a）中通過一點鏈線（左右方向）之面處切斷之情形時之立體圖。Figures 2 and 3 are diagrams showing the internal structure of the air cleaning device. Figure 2 (a) is a top view, and (b) is a front view when it is cut at a plane passing through a chain line (front and rear direction) in (a) , (C) and (d) are the perspective views when they are cut at the plane passing through a chain line (front-rear direction) in (a), FIG. 3 (a) is a top view, and (b) is in (a) Front view of the case where it is cut at the plane passing through the one-point chain line (left-right direction), (c) and (d) are the perspective views when it is cut at the plane passing through the one-point chain line (left-right direction) in (a) .

如上所述，於吸氣通路16之背面側形成有背面吸氣開口30。又，吸氣通路16之上側大幅開口，於此處形成有縱向之空氣通路32。又，於吸氣通路16之背面側上側設置有照明部34。該照明部34左右寬度方向大致整個寬度配置複數個LED，朝向斜前方照射光，藉此向吸氣通路16之大致整體供給光。As described above, the rear suction opening 30 is formed on the rear side of the suction passage 16. In addition, the upper side of the suction passage 16 is largely opened, and a longitudinal air passage 32 is formed here. In addition, an illumination portion 34 is provided on the upper side of the back surface side of the intake passage 16. The illumination portion 34 has a plurality of LEDs arranged substantially across the entire width in the left-right width direction, and irradiates light obliquely forward, thereby supplying light to substantially the entire intake passage 16.

於空氣通路32之上配置有過濾單元40。該過濾單元40係以堵住空氣通路32之方式設置，來自空氣通路32之空氣藉由通過過濾單元40進行過濾而被淨化。過濾單元40為將長條之較薄之過濾材摺疊構成之褶狀之集塵過濾器（去除垃圾、灰塵等之過濾器）與活性碳或觸媒物質等附著於纖維材之除臭過濾器（吸附異味產生物質之過濾器）之2段構成，兩者為一體，且可拆卸。即，背面側之本體殼體12之與過濾單元40相對應之部分可拆卸，過濾單元40可於背面側拉出。再者，亦較佳為於過濾單元40之最下部設置進行簡易之過濾之預濾器。A filter unit 40 is arranged above the air passage 32. The filter unit 40 is provided so as to block the air passage 32, and the air from the air passage 32 is purified by filtering through the filter unit 40. The filter unit 40 is a pleated dust collecting filter (filter for removing garbage, dust, etc.) formed by folding a long thin filter material and activated carbon or catalyst substances and other deodorizing filters attached to the fiber material (Filter for adsorbing odor-generating substances) Two-stage structure, both of which are integrated and detachable. That is, the portion of the body case 12 on the back side corresponding to the filter unit 40 is detachable, and the filter unit 40 can be pulled out on the back side. Furthermore, it is also preferable to provide a pre-filter for simple filtration at the lowest part of the filter unit 40.

過濾單元40之上方（下游側）成為空氣通路42，該空氣通路42係朝向上方形成為楔形，截面積變小。即，形成空氣通路42之管狀之壁44於本體殼體12之內側逐漸靠近內側。並且於變窄處（小徑部分）設置有風扇罩48。該風扇罩48係以放射狀之板材將同心圓狀之板材相連而成者，藉由隔開空間進行保護以避免人手等從下方侵入。The air passage 42 is formed above (downstream side) of the filter unit 40, and the air passage 42 is formed in a wedge shape upward, and the cross-sectional area becomes small. That is, the tubular wall 44 forming the air passage 42 gradually approaches the inside of the body case 12. In addition, a fan cover 48 is provided at the narrowed portion (small diameter portion). The fan cover 48 is formed by connecting concentric circular plates with radial plates, and is protected by a space to prevent intrusion of human hands or the like from below.

又，於壁44與本體殼體12之間之空間配置有電路基板46。於該電路基板46搭載根據開關按鈕24之操作控制對風扇馬達50之電力供給之電路、及控制照明部34之照明之電路。又，於該電路基板46安裝有灰塵感測器、氣體感測器，亦根據該等感測器之檢測結果控制風扇馬達50或照明部34。再者，於本實施形態中，亦具有檢測周邊之明亮程度之照度感測器，於周邊較暗時，亦可降低風扇馬達之轉速而謀求靜音化。照度感測器設置於本體殼體12之上表面即可。In addition, a circuit board 46 is arranged in the space between the wall 44 and the body case 12. The circuit board 46 is equipped with a circuit that controls the power supply to the fan motor 50 according to the operation of the switch button 24 and a circuit that controls the lighting of the lighting unit 34. In addition, a dust sensor and a gas sensor are mounted on the circuit board 46, and the fan motor 50 or the lighting part 34 is also controlled based on the detection results of these sensors. In addition, in this embodiment, an illuminance sensor for detecting the brightness of the surroundings is also provided. When the surroundings are dark, the rotation speed of the fan motor can be reduced to achieve silence. The illuminance sensor may be disposed on the upper surface of the body casing 12.

風扇罩48之上方之空氣通路42以楔形擴展，於其上部設置有風扇馬達50。該風扇馬達50藉由支承材52固定於空氣通路42之中心部。再者，支承材52具有開口，基本上不會妨礙空氣之流通。The air passage 42 above the fan cover 48 expands in a wedge shape, and a fan motor 50 is provided on the upper part thereof. The fan motor 50 is fixed to the center of the air passage 42 by the support material 52. Furthermore, the support material 52 has an opening, which basically does not hinder the circulation of air.

風扇馬達50使旋轉葉片54旋轉而產生空氣流。由風扇馬達50及旋轉葉片54構成送風風扇56。旋轉葉片54為軸流型，送風風扇56為軸流風扇。送風風扇56吸入來自空氣通路42之空氣並向上方供給。即，使來自吸氣通路16之空氣通過過濾單元40並向上方送風。The fan motor 50 rotates the rotary blade 54 to generate an air flow. The fan motor 50 and the rotating blade 54 constitute a blower fan 56. The rotary blade 54 is an axial flow type, and the blower fan 56 is an axial flow fan. The blower fan 56 sucks air from the air passage 42 and supplies it upward. That is, the air from the intake passage 16 is passed through the filter unit 40 and blown upward.

於旋轉葉片54之上方配置有對來自送風風扇56之空氣流進行整流之靜葉60。該靜葉60由中心向上方鼓出之圓頂體、及自該圓頂體沿放射方向延伸之複數個葉片構成，使藉由旋轉葉片54送來之空氣流集中於中心方向。Above the rotating blade 54, a stationary blade 60 that rectifies the air flow from the blower fan 56 is arranged. The stationary blade 60 is composed of a dome body bulging upward from the center and a plurality of blades extending from the dome body in the radial direction, so that the air flow sent by the rotary blades 54 is concentrated in the center direction.

於靜葉60之上方之本體殼體12之上表面配置有風扇罩18。該風扇罩18整體形狀為圓形，設置複數個放射狀之桿，防止手或各種物體等進入。A fan cover 18 is disposed on the upper surface of the body casing 12 above the stationary blade 60. The overall shape of the fan cover 18 is circular, and a plurality of radial rods are provided to prevent entry of hands or various objects.

於此種空氣清淨裝置10中，藉由驅動風扇馬達50，旋轉葉片54旋轉，而形成朝向上方之空氣流。於本體殼體12內形成通過吸氣通路16、空氣通路32、過濾單元40、旋轉葉片54、靜葉60、風扇罩18之空氣流路，如圖4所示，自前表面吸氣開口14、背面吸氣開口30吸入之室內之空氣通過空氣流路，被向上方送出。In such an air purifying device 10, by driving the fan motor 50, the rotary blade 54 rotates to form an upward air flow. An air flow path through the suction passage 16, the air passage 32, the filter unit 40, the rotating blade 54, the stationary blade 60, and the fan cover 18 is formed in the body casing 12, as shown in FIG. 4, the suction opening 14 from the front surface, The air in the room sucked by the rear suction opening 30 is sent upward through the air flow path.

「照明部34之構成」 圖5表示照明部34之構成。圖5（a）為自前方觀察之圖，（b）為自吸氣通路16內觀察後上方之圖（表示照明部之一部分），（c）為表示於前後方向之面處切斷之截面之圖。"Composition of the lighting section 34" FIG. 5 shows the structure of the lighting unit 34. Fig. 5 (a) is a diagram viewed from the front, (b) is a diagram viewed from the inside of the intake passage 16 at the upper rear (indicating a part of the lighting part), and (c) is a cross section cut at the front-rear surface Picture.

照明部34具有半圓筒狀之透明蓋100，其於吸氣通路16之後上部固定於本體殼體12之背面部。於透明蓋100之內部空間以向左右方向延伸之方式配置有板狀之LED基板102。該LED基板102之表面朝向斜前下方。並且，於該LED基板102橫向隔開間隔配置有複數個LED元件104。因此，藉由使複數個LED元件104發光，可向其下方及前方側射出光，而向吸氣通路16之大致整體供給光。再者，自電路基板46向該LED元件104供給電力。The lighting portion 34 has a semi-cylindrical transparent cover 100, and its upper portion is fixed to the back portion of the main body casing 12 after the suction passage 16. A plate-shaped LED substrate 102 is arranged in the internal space of the transparent cover 100 so as to extend in the left-right direction. The surface of the LED substrate 102 faces diagonally downward and forward. In addition, a plurality of LED elements 104 are arranged on the LED substrate 102 at intervals in the lateral direction. Therefore, by making a plurality of LED elements 104 emit light, light can be emitted to the lower side and the front side thereof, and light can be supplied to substantially the entire intake passage 16. Furthermore, the LED element 104 is supplied with electric power from the circuit board 46.

「照明部34中之照度控制」 照明部34可藉由來自電路基板46之訊號而調整LED元件104之發光強度。即，可變更對吸氣通路16之照明之明亮程度。"Illumination control in the lighting section 34" The illumination part 34 can adjust the light emission intensity of the LED element 104 by the signal from the circuit board 46. That is, the brightness of the illumination of the intake passage 16 can be changed.

圖6（a）～（d）表示照明部34之照明狀態。（a）為熄燈狀態，（b）為剛點燈後，（c）為點燈後經過少許時間之狀態，（d）為全點燈之（最大照度）狀態。因此，如圖6（a）～（d）般，藉由逐漸增強照明強度，可模擬如照明自後方向前方移動之狀態。如此可不使用機械移動手段而模擬移動，因此不會發出不需要之聲音，亦不會產生磨耗等問題。並且設計上亦優異。6( a) to (d) show the lighting state of the lighting unit 34. (A) is the light-off state, (b) is just after lighting, (c) is the state after a little time after lighting, (d) is the state of full lighting (maximum illumination). Therefore, as shown in FIGS. 6(a) to (d), by gradually increasing the intensity of the illumination, a state in which the illumination moves from the rear to the front can be simulated. In this way, it is possible to simulate movement without using mechanical movement means, so no unnecessary sound is produced, and no problems such as wear and tear are caused. And the design is also excellent.

又，逐漸改變照明強度，變動照明範圍區域，藉此於變動之區域中之各處容易以既定之明亮程度視認到吸氣通路16內之空氣中之灰塵。因此，使用者變得容易識別灰塵之狀態。In addition, the lighting intensity is gradually changed, and the area of the lighting range is changed, so that the dust in the air in the intake passage 16 can be easily recognized at a predetermined brightness level in various parts of the changed area. Therefore, the user becomes easy to recognize the state of dust.

例如，藉由打開電源開關，自剛啟動空氣清淨裝置10後起開始照明部34之照明，可將熄燈狀態至最大照度之照明狀態之變動重複1次或既定之複數次。For example, by turning on the power switch, the lighting unit 34 starts lighting immediately after the air cleaning device 10 is started, and the change of the lighting state from the light-off state to the maximum illuminance can be repeated once or a predetermined number of times.

其後，以與由使用者之操作設定之送風風扇之送風強度（風扇強度）相應之照度，動作過程中繼續照明。After that, the illumination is continued during the operation with the illuminance corresponding to the air supply intensity (fan intensity) of the air supply fan set by the user's operation.

如下文所述，風扇強度有複數級（至少3級），根據風扇強度，風扇強度越大，照明部34之照明強度越大。As described below, the fan intensity has a plurality of levels (at least 3 levels). According to the fan intensity, the greater the fan intensity, the greater the illumination intensity of the lighting portion 34.

又，於變更送風模式時，發光強度暫時變弱後，設定為與該模式相對應之發光強度。藉此，可確實地識別已進行操作。In addition, when the air supply mode is changed, after the luminous intensity is temporarily weakened, the luminous intensity corresponding to the mode is set. With this, it is possible to reliably recognize that the operation has been performed.

再者，在停留於既定之點燈狀態之狀態經過既定時間之情形時，亦可進行如上所述之照度變更。進而，於持續運行既定時間之情形時，可熄燈，於熄燈時間經過既定時間之情形時，能以既定之強度點燈，或進行如上所述之照度之變更。In addition, when the state staying in the predetermined lighting state passes a predetermined time, the illuminance can be changed as described above. Furthermore, in the case of continuous operation for a predetermined time, the light can be turned off, and when the light-off time passes the predetermined time, the light can be turned on at a predetermined intensity, or the illuminance can be changed as described above.

此處，如下文所述，關於送風模式，除了如手動下之「強」「中」「弱」之風扇強度之設定以外，有自動變更風扇強度之「自動模式」。於該自動模式下，於風扇強度經變更之情形時，暫時降低照明強度後，可設為與所設定之風扇強度相對應之照明強度。藉此，使用者容易識別風扇強度經自動變更。使用者可期待變化。Here, as described below, with regard to the air supply mode, in addition to the "Strong", "Medium", and "Weak" fan strength settings under Manual, there is an "Automatic Mode" that automatically changes the fan strength. In this automatic mode, when the fan intensity is changed, after temporarily reducing the illumination intensity, the illumination intensity corresponding to the set fan intensity can be set. In this way, the user can easily recognize that the fan intensity has been automatically changed. Users can expect changes.

「過濾單元40之構成」 過濾單元40如上所述可向外部取出。圖7表示取出過濾單元40之狀態，（a）表示取出之狀態，（b）表示自過濾單元40取出除臭過濾器之動作。"Configuration of Filter Unit 40" The filter unit 40 can be taken out to the outside as described above. FIG. 7 shows a state where the filter unit 40 is taken out, (a) shows a state taken out, and (b) shows an operation of taking out the deodorizing filter from the filter unit 40.

如上所述，集塵過濾器110及除臭過濾器114被收容至過濾器框112內。另外，如圖7（a）所示，本體殼體12之與過濾單元40相對應之背面部成為可拆卸之蓋118，藉由將該蓋118拆卸，過濾單元40可以一體形式出入本體殼體12內外。因此，可視需要拆下過濾單元40，清掃過濾器並裝回、或更換過濾器。此處，如圖7（b）所示，除臭過濾器114，其周邊由過濾器框112內壁之階差所支承。另外，於過濾器框112之近側壁之上端部自由轉動地安裝有擋板116。藉由將擋板116自近側向裏側旋轉，其前端部掛住除臭過濾器114之近側之上表面而夾入除臭過濾器114。另一方面，藉由將擋板116自裏側向近側轉動，擋板116之前端自除臭過濾器114脫離，而可自過濾器框112內取出除臭過濾器114。As described above, the dust collection filter 110 and the deodorization filter 114 are accommodated in the filter frame 112. In addition, as shown in FIG. 7( a ), the back portion of the body casing 12 corresponding to the filter unit 40 becomes a removable cover 118. By removing the cover 118, the filter unit 40 can be integrated into and out of the body casing 12 inside and outside. Therefore, the filter unit 40 may be removed as necessary, the filter is cleaned and replaced, or the filter is replaced. Here, as shown in FIG. 7( b ), the periphery of the deodorizing filter 114 is supported by the step difference of the inner wall of the filter frame 112. In addition, a baffle 116 is rotatably attached to the upper end portion of the near side wall of the filter frame 112. By rotating the baffle 116 from the near side to the back side, the front end portion of the deodorizing filter 114 is caught by the upper surface of the near side of the deodorizing filter 114. On the other hand, by turning the baffle 116 from the inner side to the near side, the front end of the baffle 116 is separated from the deodorizing filter 114, and the deodorizing filter 114 can be taken out from the filter frame 112.

「過濾單元40之***部分之構成」 圖8（a）～（d）表示過濾單元40之***部分之構成。（a）係於本體殼體12內***有過濾單元40之內部狀態，（b）係自本體殼體12內取出過濾單元40之內部狀態，（c）係自本體殼體12內取出過濾單元40之狀態之立體圖，（d）為表示支承單元之內部構造之圖。"Structure of the inserted part of the filter unit 40" 8(a) to (d) show the structure of the insertion portion of the filter unit 40. FIG. (A) The internal state of the filter unit 40 inserted in the main body case 12, (b) The internal state of the filter unit 40 taken out from the main body case 12, (c) The filter unit taken out of the main body case 12 A perspective view of the state of 40, (d) is a diagram showing the internal structure of the support unit.

過濾單元40***之本體殼體12內之空間與過濾單元40相比稍大。另外，藉由將過濾單元40之框狀之上端面（過濾器框112之上端）向上推，可氣密地連接（密封）於上方之空氣通路42。The space in the body case 12 into which the filter unit 40 is inserted is slightly larger than that of the filter unit 40. In addition, by pushing up the frame-shaped upper end surface of the filter unit 40 (the upper end of the filter frame 112), the upper air passage 42 can be hermetically connected (sealed).

為此，於過濾單元40***之本體殼體12內之空間的下側之左右兩端部配置有支承單元120。該支承單元120包含：於內部包含上下方向之彈簧之一對彈簧單元122、將上下方向之移動抑制為既定值以下之一對支承體124、及形成上表面之上表面板126。For this reason, support units 120 are arranged on the left and right ends on the lower side of the space in the body case 12 into which the filter unit 40 is inserted. The support unit 120 includes a pair of spring units 122 including a pair of springs in the up-down direction inside, a pair of support bodies 124 that suppress movement in the up-down direction below a predetermined value, and an upper surface plate 126 formed on the upper surface.

上表面板126於近側及裏側成為傾斜部，中間部成為平坦部。因此，於自背面側***過濾單元40之情形時，首先過濾單元40之前部下端與上表面板126之傾斜部相接，其後壓入過濾單元40，藉此支承單元120抵抗彈簧力而向下方移動。因此，於該狀態下藉由將過濾單元40壓入前方側而結束過濾單元40之***之情形時，藉由放開過濾單元40，而利用支承單元120之彈簧力將過濾單元40推向上方。The upper surface plate 126 becomes an inclined portion on the near side and the back side, and the middle portion becomes a flat portion. Therefore, when the filter unit 40 is inserted from the back side, first the lower end of the front of the filter unit 40 is in contact with the inclined portion of the upper surface plate 126, and then pressed into the filter unit 40, whereby the support unit 120 resists the spring force Move down. Therefore, when the filter unit 40 is inserted into the front side by pressing the filter unit 40 in this state, the filter unit 40 is released and the filter unit 40 is pushed upward by the spring force of the support unit 120 .

又，於取出過濾單元40時，由於支承單元120亦可向下移動，故而可容易地取出。再者，過濾單元40之下方為與吸氣通路16連接之外部氣體之吸入口，無需密封。In addition, when the filter unit 40 is taken out, since the support unit 120 can also move downward, it can be taken out easily. Furthermore, below the filter unit 40 is a suction port for external air connected to the suction passage 16, and no sealing is required.

「旋轉葉片54及靜葉60之構成」 圖9表示旋轉葉片54之構成例。如上所述，於中心之圓筒狀之芯材130之周緣安裝有複數個葉片132。葉片132於內側端自上端向斜下延伸，外側端以隔開些許間隙之方式位於圓筒狀通路之內周。芯材130之中心部被固定於風扇馬達50之旋轉軸。該旋轉葉片54為軸流型，藉由旋轉葉片54旋轉，而產生軸向之空氣流。"Structure of rotating blade 54 and stationary blade 60" FIG. 9 shows a configuration example of the rotary blade 54. As described above, a plurality of blades 132 are attached to the periphery of the central cylindrical core material 130. The blade 132 extends diagonally downward from the upper end at the inner end, and the outer end is located at the inner periphery of the cylindrical passage with a slight gap. The central portion of the core material 130 is fixed to the rotation shaft of the fan motor 50. The rotary blade 54 is an axial flow type, and the rotary blade 54 rotates to generate an axial air flow.

圖10表示靜葉60之構成，（a）為立體圖，（b）為俯視圖。於圓筒狀之外壁140之中心配置有向上方鼓出之形狀之圓頂部142，於外壁140與圓頂部142之間配置有沿半徑方向延伸之複數個板材144。各板材144之面相對於軸向以既定角度傾斜（同向傾斜）而稍微變斜。藉此，包含由旋轉葉片54之旋轉產生之旋轉氣流在內之空氣流藉由靜葉60矯正旋轉氣流，成為直線氣流被送向上方。FIG. 10 shows the structure of the stationary blade 60, (a) is a perspective view, and (b) is a plan view. At the center of the cylindrical outer wall 140, a dome 142 bulging upward is arranged, and between the outer wall 140 and the dome 142, a plurality of plates 144 extending in the radial direction are arranged. The surface of each plate 144 is inclined at a predetermined angle with respect to the axial direction (in the same direction) and slightly inclined. With this, the air flow including the rotating air flow generated by the rotation of the rotating blade 54 is corrected by the stationary blade 60 to form a linear air flow and sent upward.

圖11表示有靜葉60之情形與無靜葉60之情形時之空氣流之流線（解析結果）。圓周方向之空氣流動被靜葉60抑制，藉此產生朝向上方、相對筆直之空氣流。FIG. 11 shows the flow lines of the air flow (analysis result) when the stator blade 60 is present and when the stator blade 60 is not present. The air flow in the circumferential direction is suppressed by the vane 60, thereby generating a relatively straight air flow upward.

如上所述，藉由對旋轉氣流進行整流，空氣清淨機之送風量增加，而可進行更有效率之室內空氣之清淨。As described above, by rectifying the rotating airflow, the air supply of the air cleaner increases, and more efficient indoor air purification can be performed.

「自動模式」 實施形態之空氣清淨裝置10具有自動模式。於該自動模式下，根據各種感測器之檢測結果等對旋轉葉片54之轉速等進行控制。"Auto Mode" The air cleaning device 10 of the embodiment has an automatic mode. In this automatic mode, the rotation speed and the like of the rotary blade 54 are controlled based on the detection results of various sensors.

於藉由灰塵感測器檢測到之周圍之灰塵量較多之情形時，可增大送風風扇之強度，於藉由氣體感測器檢測到之既定之氣體量（對應於異味之強度）較多之情形時，可增大送風風扇之強度。In the case where the amount of dust in the surroundings detected by the dust sensor is large, the intensity of the blower fan can be increased, compared with the predetermined amount of gas detected by the gas sensor (corresponding to the intensity of odor) In many cases, the strength of the blower fan can be increased.

又，於藉由照度感測器檢測到周圍較暗之情形時，判斷為就寢中，為了降低動作聲音，而對風扇強度進行限制（例如，禁止風扇強度變強）。In addition, when the illuminance sensor detects a dark surrounding, it is determined that the intensity of the fan is restricted in order to reduce the motion sound during bedtime (for example, the intensity of the fan is prohibited from becoming stronger).

再者，於手動模式下，使用者可藉由按鈕操作選擇風扇強度。Furthermore, in the manual mode, the user can select the fan intensity by button operation.

此處，於分別獲得灰塵感測器及氣體感測器之檢測值之情形時，採用由兩者之感測器之檢測值獲得之風扇強度中強度較高者即可。Here, when the detection values of the dust sensor and the gas sensor are obtained separately, the fan intensity obtained from the detection values of the two sensors may be higher.

又，除臭過濾器114並非可去除與氣體感測器反應之全部種類之氣味。因此，於由氣體感測器獲得之檢測值較高而將風扇強度設定為較高之情形時，較佳為於經過一定時間時依序降低風扇強度。例如，於與氣體感測器之檢測值相對應之風扇強度等級為強之情形時，可每隔既定時間依序減弱為中、弱、空轉等。In addition, the deodorizing filter 114 is not capable of removing all kinds of odors that react with the gas sensor. Therefore, when the detection value obtained by the gas sensor is high and the fan intensity is set to be high, it is preferable to sequentially decrease the fan intensity after a certain period of time. For example, when the fan intensity level corresponding to the detection value of the gas sensor is strong, it can be sequentially weakened to medium, weak, idling, etc. at a predetermined time.

風扇強度例如可設置強、中、弱之3個等級。For example, the fan strength can be set in three levels: strong, medium and weak.

於欲在短時間內清淨房間之空氣時，亦較佳為藉由使用者之操作選擇噴射清潔模式，使風扇以高速動作既定時間。When you want to clean the air in the room in a short time, it is also better to select the spray cleaning mode by the user's operation, so that the fan operates at a high speed for a predetermined time.
