The guide member 26 is provided with support portions 66 at two locations facing each other in the diameter direction (refer mainly to FIG. 8 ). These support portions 66 protrude downward from the guide member 26 and protrude toward the central side of the guide member 26. One side of the support portion 66 in the circumferential direction is open, and the other side is closed. An anti-detachment portion 67 protruding upward is provided at the lower edge of the opening side of the support portion 66. Furthermore, the structure is such that one side of the opening of the support portion 66 at the two locations is consistent. For example, if the rearmost side in the clockwise direction of the circumferential direction of one of the supporting parts 66 is open, the rearmost side in the clockwise direction of the circumferential direction of the other supporting part 66 is also open. Furthermore, three or more supporting parts may be provided.
而且，控制基板27被配設在外部框體24的下部區域11b且本體部30的凸緣部36與裝飾框32之間的控制基板收容部54。控制基板27包括控制電路，所述控制電路輸入從電源部12通過線纜13而供給的電力，將電力通過風扇用的配線供給至風扇25而進行控制，並且將電力通過配線44供給至處理單元17（紫外線光源及可見光光源）而進行控制。Furthermore, the control substrate 27 is disposed in the control substrate storage portion 54 between the flange portion 36 of the main body 30 and the decorative frame 32 in the lower region 11b of the outer frame 24. The control substrate 27 includes a control circuit that receives power supplied from the power supply unit 12 through the cable 13, supplies power to the fan 25 through the fan wiring to control it, and supplies power to the processing unit 17 (ultraviolet light source and visible light source) through the wiring 44 to control it.
在控制電路中，包含探測人體的人感感測器69、顯示空氣處理裝置10的狀態的兩個監測燈70、切換空氣處理裝置10的動作模式的兩個操作部71、72。The control circuit includes a human body sensor 69 for detecting a human body, two monitoring lights 70 for displaying the status of the air treatment device 10, and two operating parts 71 and 72 for switching the operation mode of the air treatment device 10.
人感感測器69是以與裝飾框32的探測孔60相向的方式而配置，探測空氣處理裝置10的下方區域的人體的有無或人體的移動。兩個監測燈70是以與裝飾框32的兩個監測孔61分別相向的方式而配置，通過發光色或者點亮、熄滅、閃爍等來顯示空氣處理裝置10的動作狀態。The human sensor 69 is arranged to face the detection hole 60 of the decorative frame 32, and detects the presence or movement of a human body in the lower area of the air treatment device 10. The two monitoring lights 70 are arranged to face the two monitoring holes 61 of the decorative frame 32, and display the operating state of the air treatment device 10 by emitting light colors or lighting, extinguishing, flashing, etc.
操作部71、操作部72例如為滑動開關，以與平面部62的操作孔63相向的方式而配置，且構成為，在經配置的狀態下可經由操作孔63而在沿著平面部62的橫向上進行滑動操作。操作部71、操作部72在圖7所示的俯視時比起下部區域11b的下側即裝飾框32的外周面更靠內側配置。即，構成為，在空氣處理裝置10配設於天花板的狀態下，從空氣處理裝置10的正下方觀察空氣處理裝置10時，無法看到操作部71、操作部72。例如也可為，操作部71、操作部72可通過滑動操作來多階段地切換，在平面部62，與操作部71、操作部72的切換位置對應地顯示有所切換的模式名。The operation parts 71 and 72 are, for example, slide switches, which are arranged in a manner facing the operation hole 63 of the plane part 62, and are configured so that they can be slid in the horizontal direction along the plane part 62 through the operation hole 63 in the configured state. The operation parts 71 and 72 are arranged more inward than the lower side of the lower area 11b, that is, the outer peripheral surface of the decorative frame 32 when viewed from above as shown in FIG. 7. That is, the operation parts 71 and 72 are configured so that when the air treatment device 10 is arranged on the ceiling, the air treatment device 10 is observed from directly below the air treatment device 10, and the operation parts 71 and 72 cannot be seen. For example, the operation parts 71 and 72 can be switched in multiple stages by sliding operation, and the names of the switched modes are displayed on the plane part 62 corresponding to the switching positions of the operation parts 71 and 72.
在控制基板27，電連接有安裝探測開關73，所述安裝探測開關73探測處理單元17在本體單元16被安裝於規定的安裝位置的情況。安裝探測開關73被配置在裝飾框32的安裝槽部57的位置。控制基板27的控制電路進行控制，以使得在由安裝探測開關73探測到處理單元17的安裝的狀態下，可進行對風扇25或紫外線光源單元78側的電力供給，而且，在安裝探測開關73未探測到處理單元17的安裝的狀態或者未能從探測狀態進行探測時，不進行對風扇25或紫外線光源單元78側的電力供給。即，在控制基板27中進行下述控制，即：在從本體單元16拆卸了處理單元17的狀態下，不對風扇25或者處理單元17所包括的可見光光源單元76、紫外線光源單元78（詳情將後述）供給電力。理想的是，在從本體單元16拆卸了處理單元17的狀態下，至少不對紫外線光源單元78供給電力。通過像這樣構成，能夠防止紫外線照射到拆卸處理單元17的人。而且，也可構成為，在從本體單元16拆卸了處理單元17的狀態下，對可見光光源單元76供給電力。通過像這樣構成，能夠抑制在拆卸處理單元17的作業時因房間昏暗導致作業性下降的情況。The control substrate 27 is electrically connected to an installation detection switch 73 for detecting whether the processing unit 17 is installed at a predetermined installation position in the main body unit 16. The installation detection switch 73 is arranged at the position of the installation groove portion 57 of the decorative frame 32. The control circuit of the control substrate 27 controls so that when the installation detection switch 73 detects the installation of the processing unit 17, power can be supplied to the fan 25 or the ultraviolet light source unit 78 side, and when the installation detection switch 73 does not detect the installation state of the processing unit 17 or fails to detect from the detection state, power is not supplied to the fan 25 or the ultraviolet light source unit 78 side. That is, the following control is performed in the control substrate 27, namely, when the processing unit 17 is removed from the main unit 16, power is not supplied to the fan 25 or the visible light source unit 76 and the ultraviolet light source unit 78 (details will be described later) included in the processing unit 17. Ideally, when the processing unit 17 is removed from the main unit 16, power is not supplied to at least the ultraviolet light source unit 78. By configuring in this way, it is possible to prevent ultraviolet rays from irradiating a person who removes the processing unit 17. Moreover, it is also possible to configure that power is supplied to the visible light source unit 76 when the processing unit 17 is removed from the main unit 16. By configuring in this way, it is possible to suppress the situation where workability is reduced due to the dimness of the room when the processing unit 17 is removed.
而且，圖2至圖7、圖10至圖13表示處理單元17。處理單元17包括內部框體75，在所述內部框體75，配設有可見光光源單元76、灰塵過濾器77、紫外線光源單元78、光催化劑過濾器單元79等。2 to 7 and 10 to 13 show the processing unit 17. The processing unit 17 includes an inner frame 75, in which a visible light source unit 76, a dust filter 77, an ultraviolet light source unit 78, a photocatalyst filter unit 79, and the like are disposed.
內部框體75包括處理框體部81，在所述處理框體部81的上部側安裝有上框構件82，在處理框體部81的下部側安裝有下框構件83。The inner frame 75 includes a processing frame portion 81 , an upper frame member 82 is mounted on the upper side of the processing frame portion 81 , and a lower frame member 83 is mounted on the lower side of the processing frame portion 81 .
處理框體部81例如為鋁鑄件等金屬製，且是在徑向上一分為二地形成，通過組合成圓筒狀並加以螺固而一體地構成。The processing frame portion 81 is made of metal such as aluminum casting, and is formed by being divided into two parts in the radial direction, and is integrally formed by being assembled into a cylindrical shape and screwed together.
處理框體部81為設有連接上下圓面的貫穿部的圓筒狀，作為貫穿部的處理框體部81的內部構成為空氣處理部20。並且，貫穿部的下表面側形成有連通於進氣口18側的第一口側開口即進氣側開口84，貫穿部的上表面側形成有連通於排氣口19側的第二口側開口即排氣側開口85。進氣側開口84與排氣側開口85經由空氣處理部20而連接。在與從進氣側開口84朝向排氣側開口85的線段垂直的平面中，存在排氣側開口85的剖面積（開口面積）比進氣側開口84的剖面積（開口面積）小的關係。The processing frame 81 is cylindrical and has a through-portion connecting the upper and lower circular surfaces. The interior of the processing frame 81 as the through-portion constitutes the air processing section 20. In addition, a first side opening, namely an air intake side opening 84, which is connected to the air intake port 18 is formed on the lower surface side of the through-portion, and a second side opening, namely an air exhaust side opening 85, which is connected to the air exhaust port 19 is formed on the upper surface side of the through-portion. The air intake side opening 84 and the air exhaust side opening 85 are connected via the air processing section 20. In a plane perpendicular to a line segment from the intake-side opening 84 toward the exhaust-side opening 85 , the cross-sectional area (opening area) of the exhaust-side opening 85 is smaller than the cross-sectional area (opening area) of the intake-side opening 84 .
處理框體部81的面向空氣處理部20的內表面形成為例如鏡面等高反光率的面。另外，也可在處理框體部81的內周面的內側配置內表面形成為例如鏡面等高反光率的面的、筒狀的反射體。此時，也可在處理框體部81的內周面與反射體的外周面之間設置配線空間，所述配線空間使電連接於可見光光源單元76側或紫外線光源單元78側的配線穿過。The inner surface of the processing frame portion 81 facing the air processing portion 20 is formed into a surface with a high reflectivity such as a mirror surface. In addition, a cylindrical reflector whose inner surface is formed into a surface with a high reflectivity such as a mirror surface may be arranged inside the inner peripheral surface of the processing frame portion 81. In this case, a wiring space may be provided between the inner peripheral surface of the processing frame portion 81 and the outer peripheral surface of the reflector, and the wiring space allows the wiring electrically connected to the visible light source unit 76 side or the ultraviolet light source unit 78 side to pass through.
在處理框體部81的上部側突出有筒狀部86，在所述筒狀部86的上部側且在直徑方向上相向的兩處部位，朝向外徑方向突出有卡合部87。兩個卡合部87被配置在下述位置，即，當處理單元17被***至本體單元16內的最裡側位置為止時，可越過支撐部66的防脫部67。並且，通過在本體單元16內處理單元17朝規定的安裝轉動方向（例如，俯視時為逆時針方向）轉動，兩個卡合部87越過防脫部67而卡合至支撐部66上。在此狀態下，當鬆開處理單元17的支承（例如，在用手來安裝處理單元17的情況下，放開手）時，處理單元17的卡合部87因重力而位於比支撐部66的防脫部67的高度更靠下方。因而成為下述狀態，即，若人不抬起處理單元17並使其轉動，則處理單元17不會從支撐部66脫落。即，能夠抑制處理單元17意外地從本體單元16脫落的情況，從而能夠提高安全性。而且，在卡合部87的下方配設有保持彈簧88，所述保持彈簧88接觸至支撐部66的下表面側，在與卡合部87之間包夾保持支撐部66。A cylindrical portion 86 protrudes from the upper side of the processing frame portion 81, and engaging portions 87 protrude toward the outer diameter direction at two locations on the upper side of the cylindrical portion 86 and facing each other in the diameter direction. The two engaging portions 87 are arranged at the following positions, that is, when the processing unit 17 is inserted to the innermost position in the main body unit 16, it can pass over the anti-detachment portion 67 of the support portion 66. In addition, by rotating the processing unit 17 in the main body unit 16 in a predetermined installation rotation direction (for example, counterclockwise in a top view), the two engaging portions 87 pass over the anti-detachment portion 67 and engage with the support portion 66. In this state, when the support of the processing unit 17 is released (for example, when the processing unit 17 is installed by hand, the hand is released), the engaging portion 87 of the processing unit 17 is located below the height of the anti-detachment portion 67 of the support portion 66 due to gravity. As a result, the following state is achieved, that is, unless a person lifts up the processing unit 17 and rotates it, the processing unit 17 will not fall off the support portion 66. That is, it is possible to suppress the processing unit 17 from accidentally falling off the main body unit 16, thereby improving safety. In addition, a retaining spring 88 is provided below the engaging portion 87, and the retaining spring 88 contacts the lower surface side of the support portion 66, and sandwiches and retains the support portion 66 between the engaging portion 87.

The upper frame member 82 is arranged around the cylindrical portion 86 and is mounted on the upper surface side of the processing frame portion 81. A portion of the outer periphery of the upper frame member 82 is cut off, and a connector 92 (for example, a female connector) is mounted at this position. The connector 92 is electrically connected to one end of each of the wiring for the visible light source and the wiring for the ultraviolet light source, which are electrically connected to the visible light source unit 76 side and the ultraviolet light source unit 78 side, respectively. The other end of the wiring for the visible light source passes through the processing frame portion 81, is led out downward from the lower frame member 83, and is electrically connected to the visible light source unit 76 side. The other end side of the wiring for the ultraviolet light source is electrically connected to the ultraviolet light source unit 78 side in the processing frame portion 81. In each wiring, at least the portion exposed to the air processing unit 20 in the processing frame portion 81 is covered with an insulating material or the like having excellent ultraviolet resistance, and when a cylindrical reflector is arranged on the inner side of the inner peripheral surface of the processing frame portion 81, the wiring space is passed between the inner peripheral surface of the processing frame portion 81 and the outer peripheral surface of the reflector.

The heat sink 111 may also have concave and convex portions (including tiny concave and convex portions that cannot be visually detected) on the surface to increase its surface area and improve heat dissipation performance.
紫外線光源支架112例如為金屬製，形成為中央開口的圓環狀。在紫外線光源支架112上，以在直徑方向上橫切中央的開口部分的方式安裝有配設著紫外線光源110的散熱塊111。在紫外線光源支架112，在中央的開口部分的上方，呈同心圓狀地隔開間隔而豎立設置有例如三重的遮光壁112a。遮光壁112a的圓周方向的兩端被支撐於紫外線光源支架112，相鄰的遮光壁112a之間以及中央的開口部分朝上下方向開口。紫外線光源支架112被包夾安裝在一分為二的處理框體部81間，由此配置在內部框體75的空氣處理部20的下部側，紫外線光源支架112的中央的開口部分連通於內部框體75的進氣側開口84。The ultraviolet light source bracket 112 is made of metal, for example, and is formed into a ring shape with an opening in the center. A heat sink 111 equipped with an ultraviolet light source 110 is installed on the ultraviolet light source bracket 112 in a manner that crosses the central opening in the radial direction. On the ultraviolet light source bracket 112, above the central opening, for example, three layers of light shielding walls 112a are vertically arranged at intervals in a concentric circle. Both ends of the light shielding wall 112a in the circumferential direction are supported by the ultraviolet light source bracket 112, and the adjacent light shielding walls 112a and the central opening are open in the up-down direction. The ultraviolet light source bracket 112 is sandwiched and installed between the two-divided processing frame part 81, and is thus configured on the lower side of the air processing part 20 of the inner frame 75. The central opening part of the ultraviolet light source bracket 112 is connected to the air intake side opening 84 of the inner frame 75.
而且，如圖5至圖7、圖10至圖15所示，光催化劑過濾器單元79包括：作為被保持物的光催化劑過濾器117；以及支架118，保持所述光催化劑過濾器117而可裝卸地安裝於內部框體75。光催化劑過濾器單元79從上方可裝卸地配置於內部框體75的筒狀部86的內側。5 to 7 and 10 to 15, the photocatalyst filter unit 79 includes: a photocatalyst filter 117 as a held object; and a holder 118 that holds the photocatalyst filter 117 and is detachably mounted on the inner frame 75. The photocatalyst filter unit 79 is detachably arranged on the inner side of the cylindrical portion 86 of the inner frame 75 from above.
光催化劑過濾器117為圓形的塊狀，形成有沿厚度方向貫穿的多個通氣孔119。光催化劑過濾器117在擔載體保持/塗布而擔載有氧化鈦等光催化劑，通過從紫外線光源110接受例如360 nm至420 nm的UV-A的波長成分的紫外線或可見光，生成活性酶與OH自由基，通過所生成的活性酶或OH自由基，分解空氣中的臭味成分以進行去臭、除臭，或者抑制病毒的活動。The photocatalyst filter 117 is a circular block having a plurality of vent holes 119 extending in the thickness direction. The photocatalyst filter 117 is held/coated on a carrier and carries a photocatalyst such as titanium oxide. The photocatalyst filter 117 generates active enzymes and OH radicals by receiving ultraviolet light or visible light having a wavelength component of UV-A of, for example, 360 nm to 420 nm from the ultraviolet light source 110. The generated active enzymes or OH radicals decompose odor components in the air to deodorize or suppress virus activity.
支架118例如由樹脂材料所形成。支架118包括：圓環狀或圓筒狀的底座部120；以及從所述底座部120的在直徑方向上相向的兩處部位朝上方突出設置的安裝部121。The bracket 118 is formed of, for example, a resin material. The bracket 118 includes: a base portion 120 in an annular or cylindrical shape; and mounting portions 121 protruding upward from two locations of the base portion 120 that face each other in the diameter direction.
底座部120的內徑比光催化劑過濾器117的直徑大，可將光催化劑過濾器117配置在內側。The inner diameter of the base portion 120 is larger than the diameter of the photocatalyst filter 117, so that the photocatalyst filter 117 can be arranged inside.
在底座部120的內周面的下部側且圓周方向的多處部位，突出有對配置在底座部120內側的光催化劑過濾器117進行支承的支承部122。多個支承部122中，通過最朝底座部120的中央側突出的前端側的假想圓的直徑小於光催化劑過濾器117的直徑，相對於下方而對配置於底座部120內側的光催化劑過濾器117進行防脫支撐。支承部122例如為三個，三個中的一個在底座部120的圓周上配置在從兩個安裝部121算起的中間位置，剩餘的兩個相對於所述一個而在底座部120的圓周方向上等間隔地配置，因此，三個支承部122配置在與安裝部121不同的位置。Supporting parts 122 for supporting the photocatalyst filter 117 disposed inside the base part 120 protrude from the lower side of the inner peripheral surface of the base part 120 and at multiple locations in the circumferential direction. Among the multiple supporting parts 122, the diameter of the imaginary circle of the front end side protruding most toward the central side of the base part 120 is smaller than the diameter of the photocatalyst filter 117, and the photocatalyst filter 117 disposed inside the base part 120 is supported to prevent it from coming off relative to the bottom. For example, there are three support parts 122, one of which is arranged at a middle position on the circumference of the base part 120 from the two mounting parts 121, and the remaining two are arranged at equal intervals in the circumferential direction of the base part 120 relative to the one, so that the three support parts 122 are arranged at positions different from the mounting parts 121.
在底座部120的內周面的上部側且在直徑方向上相向的兩處部位，突出設置有第一突出部123，所述第一突出部123突出至被支撐於支承部122上的光催化劑過濾器117的上表面側，且以與支承部122之間包夾光催化劑過濾器117的方式來保持所述光催化劑過濾器117。第一突出部123在未對底座部120施加負載的狀態下，兩個第一突出部123之間的距離比光催化劑過濾器117的直徑短，將光催化劑過濾器117以包夾在與支承部122之間的方式保持於底座部120。即，第一突出部123相對於上方而對配置於底座部120內側的光催化劑過濾器117進行防脫支撐。在第一突出部123的上部側，設有傾斜面124，所述傾斜面124將從上方***至支架118的光催化劑過濾器117導至兩個第一突出部123之間。First protrusions 123 are protrudingly provided at two locations on the upper side of the inner peripheral surface of the base portion 120 and facing each other in the diameter direction. The first protrusions 123 protrude to the upper surface side of the photocatalyst filter 117 supported on the support portion 122, and hold the photocatalyst filter 117 in a manner of sandwiching the photocatalyst filter 117 between the support portion 122. When no load is applied to the base portion 120, the distance between the two first protrusions 123 is shorter than the diameter of the photocatalyst filter 117, and the photocatalyst filter 117 is held on the base portion 120 in a manner of sandwiching the photocatalyst filter 117 between the support portion 122. That is, the first protrusion 123 supports the photocatalyst filter 117 disposed inside the base 120 from above to prevent it from coming off. An inclined surface 124 is provided on the upper side of the first protrusion 123 to guide the photocatalyst filter 117 inserted into the bracket 118 from above to between the two first protrusions 123.
在底座部120的內周面的下部側且相對於連結兩個第一突出部123的方向而交叉（正交）的方向的兩處部位，突出有從底座部120的內周面的突出幅度比第一突出部123小的第二突出部125。兩個第二突出部125之間的距離比光催化劑過濾器117的直徑長。在第二突出部125的上部側，設有避免從上方***至支架118的光催化劑過濾器117卡掛於第二突出部125的傾斜面126。第二突出部125設在裝卸光催化劑過濾器117時施加負載的方向上。在拆卸光催化劑過濾器117時，在超過需要地施加負載的情況下，有支架118發生破損，或者造成無法裝卸光催化劑過濾器117的狀態的擔憂。第二突出部125也作為擋塊發揮功能，以免超過需要地對支架118施加負載。即，在拆卸光催化劑過濾器117時，將第二突出部125接觸至光催化劑過濾器117的負載限制為最大負載。At two locations on the lower side of the inner circumference of the base portion 120 and in a direction intersecting (orthogonal) with respect to the direction connecting the two first protrusions 123, second protrusions 125 protrude from the inner circumference of the base portion 120 with a smaller protrusion width than the first protrusions 123. The distance between the two second protrusions 125 is longer than the diameter of the photocatalyst filter 117. At the upper side of the second protrusion 125, an inclined surface 126 is provided to prevent the photocatalyst filter 117 inserted into the bracket 118 from above from being caught on the second protrusion 125. The second protrusion 125 is provided in the direction in which a load is applied when the photocatalyst filter 117 is installed and removed. When the photocatalyst filter 117 is removed, if a load is applied more than necessary, there is a concern that the bracket 118 may be damaged or the photocatalyst filter 117 may not be installed or removed. The second protrusion 125 also functions as a stopper to prevent an excessive load from being applied to the bracket 118. That is, when the photocatalyst filter 117 is removed, the load of the second protrusion 125 contacting the photocatalyst filter 117 is limited to a maximum load.
在底座部120的內周面的下部側且連結兩個第一突出部123的方向的兩側，突出有從底座部120的內周面的突出幅度比第一突出部123小的第三突出部127。兩個第三突出部127之間的距離比光催化劑過濾器117的直徑長或者與光催化劑過濾器117的直徑相同，且比兩個第二突出部125之間的距離短。在第三突出部127的上部側，設有傾斜面128，所述傾斜面128將從上方***至支架118的光催化劑過濾器117導至兩個第三突出部127之間。On the lower side of the inner circumference of the base 120 and on both sides in the direction connecting the two first protrusions 123, a third protrusion 127 protrudes from the inner circumference of the base 120 with a smaller protrusion width than the first protrusion 123. The distance between the two third protrusions 127 is longer than the diameter of the photocatalyst filter 117 or the same as the diameter of the photocatalyst filter 117, and is shorter than the distance between the two second protrusions 125. On the upper side of the third protrusion 127, an inclined surface 128 is provided, and the inclined surface 128 guides the photocatalyst filter 117 inserted into the bracket 118 from above to between the two third protrusions 127.
兩個安裝部121包括：豎立部129，從底座部120豎立；手指鉤扣部130，從所述豎立部129的上部側朝外徑方向突出；引導凸肋131，從豎立部129的外表面側突出，並且隨著朝向上部側而突出幅度增加；以及爪部132，被設在所述引導凸肋131的上部側附近。The two mounting parts 121 include: a vertical part 129, which stands upright from the base part 120; a finger hook part 130, which protrudes from the upper side of the vertical part 129 toward the outer diameter direction; a guide rib 131, which protrudes from the outer surface side of the vertical part 129 and the protrusion amplitude increases toward the upper side; and a claw part 132, which is arranged near the upper side of the guide rib 131.
兩個安裝部121的豎立部129可卡合於設在內部框體75的筒狀部86的兩個支架安裝部89的凹陷部90，並且手指鉤扣部130可配置在支架安裝部89上。The vertical portions 129 of the two mounting portions 121 can be engaged with the recessed portions 90 of the two bracket mounting portions 89 provided on the cylindrical portion 86 of the inner frame 75 , and the finger hook portion 130 can be arranged on the bracket mounting portion 89 .
存在下述關係：兩個安裝部121的爪部132的前端間的距離比兩個支架安裝部89的凹陷部90的內側面間的距離長。通過用手指捏住兩個安裝部121而使其以彼此接近的方式發生彈性變形，從而能夠相對於兩個支架安裝部89的凹陷部90的安裝孔91來裝卸兩個安裝部121的爪部132，在安裝狀態下，彈性力朝爪部132卡合於安裝孔91的方向產生作用。The following relationship exists: the distance between the front ends of the claws 132 of the two mounting parts 121 is longer than the distance between the inner side surfaces of the recessed parts 90 of the two bracket mounting parts 89. By pinching the two mounting parts 121 with fingers and elastically deforming them to approach each other, the claws 132 of the two mounting parts 121 can be attached and detached relative to the mounting holes 91 of the recessed parts 90 of the two bracket mounting parts 89, and in the mounted state, the elastic force acts in the direction in which the claws 132 are engaged with the mounting holes 91.
兩個安裝部121的豎立部129卡合於內部框體75的兩個支架安裝部89的凹陷部90，底座部120從上方***至內部框體75的筒狀部86的內側，在***過程中，引導凸肋131接觸至支架安裝部89的凹陷部90而兩個安裝部121以接近的方式發生彈性變形後，引導凸肋131的上部側的爪部132卡合於安裝孔91，從而支架118被安裝至內部框體75的筒狀部86。The vertical portions 129 of the two mounting portions 121 engage with the recessed portions 90 of the two bracket mounting portions 89 of the inner frame 75, and the base portion 120 is inserted from above into the inner side of the cylindrical portion 86 of the inner frame 75. During the insertion process, the guide rib 131 contacts the recessed portion 90 of the bracket mounting portion 89, and after the two mounting portions 121 are elastically deformed in a close manner, the claw portion 132 on the upper side of the guide rib 131 engages with the mounting hole 91, so that the bracket 118 is mounted to the cylindrical portion 86 of the inner frame 75.
支架118在未對底座部120施加負載的狀態下，將比兩個第一突出部123之間的距離長的尺寸的光催化劑過濾器117保持於底座部120。並且，在從相對於連結兩個第一突出部123的方向而交叉的方向用手指捏住底座部120而施加有負載a的狀態下，圓環狀的底座部120以朝連結兩個第一突出部123的方向的外徑方向b擴大的方式而撓曲，由此，兩個第一突出部123之間的距離變得寬於光催化劑過濾器117的尺寸，從而具有能夠從底座部120的上方拆卸光催化劑過濾器117的尺寸關係（參照圖15）。另外，在將光催化劑過濾器117安裝於支架118時，也同樣使底座部120撓曲以使兩個第一突出部123間的距離擴大，由此能夠進行安裝。The holder 118 holds the photocatalyst filter 117 longer than the distance between the two first protrusions 123 on the base 120 when no load is applied to the base 120. Furthermore, when the base 120 is pinched with fingers in a direction intersecting the direction connecting the two first protrusions 123 and a load a is applied, the ring-shaped base 120 is bent in a manner to expand in the outer diameter direction b in the direction connecting the two first protrusions 123, thereby making the distance between the two first protrusions 123 wider than the size of the photocatalyst filter 117, thereby having a dimensional relationship that enables the photocatalyst filter 117 to be removed from the upper side of the base 120 (see FIG. 15). Furthermore, when the photocatalyst filter 117 is mounted on the bracket 118, the base portion 120 is similarly bent to increase the distance between the two first protrusions 123, thereby enabling mounting.
在將光催化劑過濾器單元79安裝至內部框體75的狀態下，光催化劑過濾器117以封閉內部框體75的排氣側開口85的方式而配設，光催化劑過濾器117及支架118的底座部120突出配置到內部框體75的空氣處理部20內。所述光催化劑過濾器117及支架118的底座部120以至少一部分與內部框體75的排氣側開口85重合的方式配設於排氣側開口85的附近，為朝向進氣口側開口84突出的突出部133。When the photocatalyst filter unit 79 is mounted to the inner frame 75, the photocatalyst filter 117 is arranged to close the exhaust side opening 85 of the inner frame 75, and the base portion 120 of the photocatalyst filter 117 and the bracket 118 is arranged to protrude into the air treatment unit 20 of the inner frame 75. The photocatalyst filter 117 and the base portion 120 of the bracket 118 are arranged near the exhaust side opening 85 of the inner frame 75 in a manner that at least a portion overlaps with the exhaust side opening 85 of the inner frame 75, and are a protrusion 133 protruding toward the air inlet side opening 84.
接下來，對空氣處理裝置10的設置進行說明。Next, the configuration of the air treatment device 10 will be described.
將佈設在天花板面上（天花板背側）的電源線從嵌埋孔引出而電連接至電源部12，將所述電源部12***至嵌埋孔而載置於天花板面上（天花板背側）。將多個安裝彈簧48以使其以沿著裝置本體11的側面的方式發生彈性變形的狀態***至嵌埋孔，通過解除安裝彈簧48的操作，多個安裝彈簧48通過彈簧力而在天花板面上展開以將裝置本體11上提至天花板面側，從而設置成下部區域11b的凸緣部36接觸至天花板面的狀態。The power cord laid on the ceiling surface (the back side of the ceiling) is led out from the embedding hole and electrically connected to the power unit 12, and the power unit 12 is inserted into the embedding hole and placed on the ceiling surface (the back side of the ceiling). The plurality of mounting springs 48 are inserted into the embedding hole in a state where they are elastically deformed along the side surface of the device body 11, and by releasing the mounting springs 48, the plurality of mounting springs 48 are expanded on the ceiling surface by the spring force to lift the device body 11 to the side of the ceiling surface, thereby setting the flange 36 of the lower area 11b in contact with the ceiling surface.
裝置本體11的嵌埋區域11a被嵌入至天花板面，下部區域11b從天花板面露出而配置於天花板面的下方空間（第一空間）即房間內。在下部區域11b，至少配置有可見光光源單元76、進氣口18、排氣口19。The embedded area 11a of the device body 11 is embedded in the ceiling surface, and the lower area 11b is exposed from the ceiling surface and arranged in the space below the ceiling surface (first space), that is, in the room. In the lower area 11b, at least the visible light source unit 76, the air inlet 18, and the air outlet 19 are arranged.
接下來，對空氣處理裝置10的動作進行說明。Next, the operation of the air treatment device 10 will be described.
通過從電源部12受到電力供給的控制基板27，對風扇25、可見光光源98、紫外線光源110供給電力而進行控制。The control board 27 receives power from the power supply unit 12, and supplies power to the fan 25, the visible light source 98, and the ultraviolet light source 110 to control them.
通過受到電力供給的可見光光源98點亮，從而對房間內照射可見光。即便在下部區域11b設有進氣口18的情況下，通過將進氣口18設為圓環狀，可見光光源98也能夠配置於所述進氣口18的內側。The visible light source 98 supplied with electric power is turned on to illuminate the room with visible light. Even if the air inlet 18 is provided in the lower area 11b, the visible light source 98 can be arranged inside the air inlet 18 by providing the air inlet 18 in a ring shape.
通過受到電力供給的風扇25旋轉，從而房間內的空氣通過連接進氣口18與排氣口19的流路22而迴圈。即，房間內的空氣通過處理單元17的下部區域11b的進氣口18、灰塵過濾器77、進氣側開口85而被吸入至空氣處理部20的內部（空氣處理部20的內部空間即第三空間），被吸入至空氣處理部20的空氣通過被照射紫外線，而且，通過光催化劑的作用而受到空氣處理。隨後，通過光催化劑過濾器117的多個通氣孔119、排氣側開口85而被吸入至風扇25的下表面側。從風扇25的周面側噴出的空氣由引導構件26的導風部65朝向下方的外部框體24的內周面與內部框體75的外周面之間的外側路徑21導風，並通過所述外側路徑21而從排氣口19排出至房間內。而且，空氣的流路22通過第一口18a、由外部框體24與內部框體75夾著的外側路徑21、空氣處理部20、第二口19a。另外，在將外部框體24設置於被設置面的狀態下，第一口18a相對於第一空間而開口，第二口19a相對於第一空間而開口。The fan 25 supplied with electric power rotates, so that the air in the room circulates through the flow path 22 connecting the air inlet 18 and the air outlet 19. That is, the air in the room is sucked into the interior of the air treatment unit 20 (the interior space of the air treatment unit 20, i.e., the third space) through the air inlet 18, the dust filter 77, and the air inlet side opening 85 of the lower area 11b of the processing unit 17. The air sucked into the air treatment unit 20 is irradiated with ultraviolet rays and is treated by the action of the photocatalyst. Subsequently, the air is sucked into the lower surface side of the fan 25 through the multiple vents 119 of the photocatalyst filter 117 and the air outlet side opening 85. The air ejected from the peripheral surface side of the fan 25 is guided by the air guide portion 65 of the guide member 26 toward the outer path 21 between the inner peripheral surface of the outer frame 24 and the outer peripheral surface of the inner frame 75 below, and is discharged from the exhaust port 19 into the room through the outer path 21. Moreover, the air flow path 22 passes through the first port 18a, the outer path 21 sandwiched by the outer frame 24 and the inner frame 75, the air processing unit 20, and the second port 19a. In addition, when the outer frame 24 is set on the set surface, the first port 18a is open to the first space, and the second port 19a is open to the first space.
在流路22上，在進入比空氣處理部20更靠上方的風扇25之前的流路22的一部分與進入風扇25之後的流路22的一部分中，存在空氣的流動方向相差180度的區域。In flow path 22 , between a portion of flow path 22 before entering fan 25 above air processing unit 20 and a portion of flow path 22 after entering fan 25 , there is a region where the flow direction of air differs by 180 degrees.
由於像這樣形成包含外部框體24與可裝卸至所述外部框體24內的內部框體75之間的外側路徑21的流路22，因此不需要為了形成流路22而在裝置內配設流路形成構件，能夠簡化結構。Since the flow path 22 including the outer path 21 between the outer frame 24 and the inner frame 75 that can be loaded and unloaded into the outer frame 24 is formed in this way, it is not necessary to arrange a flow path forming member in the device in order to form the flow path 22, and the structure can be simplified.
由於排氣口19朝向外部框體24的側方而設，因此從排氣口19排出的空氣容易流動至房間內的廣範圍，從而能夠提高房間的空氣處理效果。Since the exhaust port 19 is disposed toward the side of the outer frame 24, the air exhausted from the exhaust port 19 can easily flow to a wide range in the room, thereby improving the air treatment effect of the room.
通過受到電力供給的紫外線光源110點亮，從而對空氣處理部20的內部照射紫外線，通過空氣處理部20內部的空氣得到殺菌。When the ultraviolet light source 110 is powered and turned on, the interior of the air treatment unit 20 is irradiated with ultraviolet light, and the air passing through the interior of the air treatment unit 20 is sterilized.
來自紫外線光源110的紫外線也被照射至相向地配置的光催化劑過濾器117。在光催化劑過濾器117中，通過照射從紫外線光源110照射的至少360 nm至420 nm的UV-A的波長成分的紫外區域的光或可見光，從而生成活性酶與OH自由基，通過所生成的活性酶或OH自由基，分解空氣中的臭味成分以進行去臭、除臭，或者抑制病毒的活動。The ultraviolet light from the ultraviolet light source 110 is also irradiated to the photocatalyst filter 117 disposed opposite to it. In the photocatalyst filter 117, by irradiating the ultraviolet region light or visible light of at least 360 nm to 420 nm UV-A wavelength component irradiated from the ultraviolet light source 110, active enzymes and OH free radicals are generated, and the generated active enzymes or OH free radicals decompose the odor components in the air to deodorize, remove odor, or inhibit the activity of viruses.
而且，在空氣處理部20，作為突出部133的、光催化劑過濾器117及支架118的底座部120朝向進氣口側開口84突出，以封閉排氣側開口85。因此，在空氣處理部20的上部側，在空氣處理部20的側壁面與光催化劑過濾器117及支架118的底座部120的周圍之間，形成使空氣的流動產生渦流的滯留空間135（參照圖5）。Furthermore, in the air treatment unit 20, the base portion 120 of the photocatalyst filter 117 and the bracket 118 as the protrusion 133 protrudes toward the air inlet side opening 84 to close the exhaust side opening 85. Therefore, on the upper side of the air treatment unit 20, between the side wall surface of the air treatment unit 20 and the periphery of the base portion 120 of the photocatalyst filter 117 and the bracket 118, a stagnation space 135 is formed to generate swirl in the flow of air (see FIG. 5 ).
從進氣側開口84吸入的空氣的一部分在滯留空間135內成為渦流而產生滯留後，從光催化劑過濾器117的通氣孔119排出至風扇25側。通過所述空氣的流動產生滯留，能夠延長空氣在空氣處理部20內停留的時間，結果，能夠延長來自紫外線光源110的紫外線的照射時間或受到光催化劑的作用的時間，從而能夠提高空氣處理效果。A portion of the air sucked from the air intake side opening 84 becomes eddy current and stagnates in the stagnation space 135, and then is discharged from the vent hole 119 of the photocatalyst filter 117 to the fan 25 side. The stagnation caused by the flow of the air can extend the time the air stays in the air treatment unit 20, and as a result, the irradiation time of the ultraviolet light from the ultraviolet light source 110 or the time of being acted on by the photocatalyst can be extended, thereby improving the air treatment effect.
若空氣處理部20的排氣側開口85的剖面積小於進氣側開口84的剖面積，則通過光催化劑過濾器117以封閉排氣側開口85的方式而配設，容易產生滯留空間135內的空氣的渦流，從而能夠使空氣的流動產生滯留。If the cross-sectional area of the exhaust-side opening 85 of the air treatment unit 20 is smaller than the cross-sectional area of the intake-side opening 84, the photocatalyst filter 117 is arranged to close the exhaust-side opening 85, which makes it easy to generate eddy currents of the air in the stagnant space 135, thereby causing stagnation of the air flow.
紫外線光源110配置在進氣側開口84的上方且從進氣側開口84進入的空氣所吹到的位置，由此，能夠阻礙從進氣側開口84進入的空氣直接流動至排氣側開口85，容易使空氣的流動產生滯留。The ultraviolet light source 110 is disposed above the air intake side opening 84 and at a position where the air entering from the air intake side opening 84 blows, thereby preventing the air entering from the air intake side opening 84 from directly flowing to the exhaust side opening 85, making it easy for the air flow to be stagnant.
而且，通過設為從進氣側開口84進入的空氣吹到紫外線光源110的結構，能夠使來自紫外線光源110的熱容易地散發，從而能夠期待降低紫外線光源110的溫度。Furthermore, by adopting a structure in which the air entering from the air intake side opening 84 is blown toward the ultraviolet light source 110, the heat from the ultraviolet light source 110 can be easily dissipated, and thus it can be expected that the temperature of the ultraviolet light source 110 can be lowered.
而且，空氣處理裝置10是由控制基板27的控制電路基於人感感測器69的探測來控制動作。當人感感測器69探測到進入探測區域的人體時，點亮可見光光源98並使風扇25旋轉，並且使紫外線光源110點亮。可見光光源98的點亮與熄滅的切換、風扇25的旋轉與停止以及紫外線光源110的點亮與熄滅的切換可通過對操作部71、操作部72進行操作來選擇動作模式而切換。Furthermore, the air treatment device 10 is controlled by the control circuit of the control substrate 27 based on the detection of the human sensor 69. When the human sensor 69 detects a human body entering the detection area, the visible light source 98 is turned on, the fan 25 is rotated, and the ultraviolet light source 110 is turned on. The switching of the visible light source 98 on and off, the rotation and stop of the fan 25, and the switching of the ultraviolet light source 110 on and off can be switched by operating the operating unit 71 and the operating unit 72 to select the action mode.
作為運轉模式，包含：將可見光光源98的照度切換為「亮」、 「關」、「暗」的模式；將風扇25的風量切換為「強」、「弱」的模式；以及對從人感感測器69探測到人體直至熄滅可見光光源98為止的多階段的時間、直至停止風扇25及熄滅紫外線光源110為止的時間進行切換的多階段的模式等，對各操作部71、操作部72設定這些模式中的任一種。The operation modes include: switching the illumination of the visible light source 98 to "bright", "off", and "dark" modes; switching the air volume of the fan 25 to "strong" and "weak" modes; and a multi-stage mode for switching the time from when the human body is detected by the human sensor 69 to when the visible light source 98 is extinguished, and the time until the fan 25 is stopped and the ultraviolet light source 110 is extinguished, etc. Any one of these modes can be set for each operating unit 71 and operating unit 72.
操作部71、操作部72被設在露出於房間的下部區域11b的側部，因此能夠容易地進行切換操作。不需要為了操作而拆卸處理單元17等的動作。並且，操作部71、操作部72被配置在設於下部區域11b的圓周狀周面的一部分的平面部62，因此容易操作。The operation parts 71 and 72 are provided on the side of the lower area 11b exposed to the room, so the switching operation can be easily performed. There is no need to disassemble the processing unit 17 for operation. In addition, the operation parts 71 and 72 are arranged on the flat surface part 62 provided on a part of the circumferential surface of the lower area 11b, so they are easy to operate.
進而，由於在下部區域11b的上側設有平面部62，下部區域11b的下側呈圓弧狀設置，因此在仰視配置於天花板面的下部區域11b時，操作部71、操作部72被下部區域11b隱藏，能夠提高設計性。而且，不瞭解裝置結構的人即便是觀察，也不知曉操作部71、操作部72的存在，因此也能夠防止惡作劇。Furthermore, since the flat surface 62 is provided on the upper side of the lower area 11b and the lower side of the lower area 11b is provided in an arc shape, when the lower area 11b disposed on the ceiling is viewed upward, the operation parts 71 and 72 are hidden by the lower area 11b, thereby improving the design. Furthermore, even if a person who does not understand the structure of the device observes, he or she will not know the existence of the operation parts 71 and 72, thereby preventing mischief.
進而，在下部區域11b的上側，下部區域11b的下側的圓周部分相對於平面部62而突出，因此有手指等卡掛住而對下部區域11b下側的裝飾框32施加朝下的負載的擔憂。在對裝飾框32施加有朝下的負載的情況下，有朝拆卸裝飾面部52的方向施加力而導致裝飾面部52脫落、受到損壞的擔憂。本實施方式中，通過從平面部62突出有突出部64，能夠抑制手指等卡掛於下部區域11b下側的圓周部分，例如在對操作部71、操作部72進行操作時，能夠防止對下部區域11b下側的裝飾框32施加朝下的負載。並且，突出部64突出至平面部62的兩個操作部71、操作部72間，因此能夠防止在對操作部71、操作部72的其中一者進行操作時誤操作另一者的情況。Furthermore, on the upper side of the lower region 11b, the circumferential portion of the lower side of the lower region 11b protrudes relative to the flat portion 62, so there is a concern that a finger or the like may get caught and a downward load may be applied to the decorative frame 32 on the lower side of the lower region 11b. When a downward load is applied to the decorative frame 32, there is a concern that a force may be applied in a direction of removing the decorative surface 52, causing the decorative surface 52 to fall off and be damaged. In this embodiment, by having the protrusion 64 protrude from the flat portion 62, it is possible to suppress a finger or the like from getting caught on the circumferential portion on the lower side of the lower region 11b, and for example, when operating the operating portion 71, the operating portion 72, it is possible to prevent a downward load from being applied to the decorative frame 32 on the lower side of the lower region 11b. Furthermore, the protrusion 64 protrudes between the two operating portions 71 and 72 of the planar portion 62 , thereby preventing the operation of one of the operating portions 71 and 72 from being mistakenly performed.
而且，通過確認設在下部區域11b的監測燈70的顯示，能夠確認空氣處理裝置10的狀態。在監測燈70中，例如通過發光色或點亮、熄滅、閃爍等來顯示異常、空氣處理中（殺菌中）、光催化劑過濾器117的更換時期、紫外線光源110的壽命等。Furthermore, by checking the display of the monitoring lamp 70 provided in the lower area 11b, the state of the air treatment device 10 can be checked. The monitoring lamp 70 displays abnormality, air treatment (sterilization), replacement period of the photocatalyst filter 117, life of the ultraviolet light source 110, etc., for example, by luminous color or lighting, extinguishing, flashing, etc.
而且，光催化劑過濾器117會伴隨使用時間的經過而有污垢附著，從而對處理能力產生影響，因此優選的是定期地進行清洗。此時，將從本體單元16拆卸處理單元17來進行作業。Moreover, the photocatalyst filter 117 will be covered with dirt as the use time passes, thereby affecting the processing ability, so it is preferably cleaned regularly. At this time, the processing unit 17 will be disassembled from the main unit 16 to perform the operation.
在從本體單元16拆卸處理單元17時，一邊上推處理單元17，一邊使處理單元17朝拆卸方向（仰視時為逆時針方向）轉動，以使處理單元17的裝卸標記95從本體單元16的安裝標記59b的位置移動到裝卸標記59a的位置。When removing the processing unit 17 from the main unit 16, push the processing unit 17 upward while rotating it in the removal direction (counterclockwise when viewed from above) so that the loading and unloading mark 95 of the processing unit 17 moves from the position of the installation mark 59b of the main unit 16 to the position of the loading and unloading mark 59a.
通過上推處理單元17，處理單元17的卡合部87移動到足以不與本體單元16的支撐部66的防脫部67產生干涉的高度、或者卡合部87足以越過防脫部67的高度，在此狀態下，使處理單元17朝拆卸方向轉動，由此，卡合部87從支撐部66上通過一側的開口側而拆卸，且裝卸引導部97從安裝槽部57移動至裝卸槽部56。By pushing up the processing unit 17, the engaging portion 87 of the processing unit 17 moves to a height that is sufficient to not interfere with the anti-detachment portion 67 of the supporting portion 66 of the main body unit 16, or the engaging portion 87 is high enough to pass over the anti-detachment portion 67. In this state, the processing unit 17 is rotated in the disassembly direction, thereby, the engaging portion 87 is removed from the supporting portion 66 through an opening side on one side, and the loading and unloading guide portion 97 moves from the mounting groove portion 57 to the loading and unloading groove portion 56.
通過所述裝卸引導部97從安裝槽部57移動至裝卸槽部56，安裝探測開關73斷開，不再探測處理單元17的安裝。因此，即便處於對空氣處理裝置10供給有電力的狀態下，控制基板27的控制電路也控制為不進行對風扇25或紫外線光源單元78側的電力供給。By moving the loading and unloading guide 97 from the installation groove 57 to the loading and unloading groove 56, the installation detection switch 73 is turned off and the installation of the processing unit 17 is no longer detected. Therefore, even if the air treatment device 10 is supplied with power, the control circuit of the control substrate 27 is controlled not to supply power to the fan 25 or the ultraviolet light source unit 78.
一邊支承著處理單元17一邊使其朝下方移動，從而取出到本體單元16的下方。處理單元17利用配線44而與本體單元16連接，但當使處理單元17朝下方移動時，配線44受到拉拽，由此，按壓構件45的臂部47克服施力而朝下方擺動，從而容許處理單元17朝向本體單元16下方的取出。從已取出到本體單元16下方的處理單元17的連接器92拆卸配線44的連接器43。已拆卸的配線44通過按壓構件45的施力而由臂部47上提至上方，並且被按壓至外部框體24的內側面。The processing unit 17 is supported while being moved downward, and thus taken out to the bottom of the main body unit 16. The processing unit 17 is connected to the main body unit 16 by the wiring 44, but when the processing unit 17 is moved downward, the wiring 44 is pulled, and thus the arm 47 of the pressing member 45 overcomes the applied force and swings downward, thereby allowing the processing unit 17 to be taken out toward the bottom of the main body unit 16. The connector 43 of the wiring 44 is detached from the connector 92 of the processing unit 17 that has been taken out to the bottom of the main body unit 16. The detached wiring 44 is lifted upward by the arm 47 due to the applied force of the pressing member 45, and is pressed to the inner side surface of the external frame 24.
並且，在從處理單元17拆卸光催化劑過濾器117時，用手指捏住支架118的兩個安裝部121的手指鉤扣部130而使其以彼此接近的方式發生彈性變形，由此，從兩個支架安裝部89的凹陷部90的安裝孔91拆下兩個安裝部121的爪部132，在此狀態下，朝上方上提支架118，由此從內部框體75拆卸支架118。Furthermore, when removing the photocatalyst filter 117 from the processing unit 17, the finger hook portions 130 of the two mounting portions 121 of the bracket 118 are pinched with fingers so as to elastically deform them in a manner so as to approach each other, thereby removing the claw portions 132 of the two mounting portions 121 from the mounting holes 91 of the recessed portions 90 of the two bracket mounting portions 89. In this state, the bracket 118 is lifted upward, thereby removing the bracket 118 from the inner frame 75.
從相對於連結所拆卸的支架118的兩個第一突出部123的方向而交叉的方向用手指捏住底座部120來施加負載a，由此，圓環狀的底座部120以朝連結兩個第一突出部123的方向的外徑方向b擴大的方式而撓曲，兩個第一突出部123之間的距離變得寬於光催化劑過濾器117的尺寸，能夠使光催化劑過濾器117朝底座部120的上方移動而予以拆卸。對所拆卸的光催化劑過濾器117進行清洗。The base 120 is pinched with fingers in a direction intersecting the direction of the two first protrusions 123 connecting the bracket 118 to be removed to apply a load a, thereby bending the ring-shaped base 120 in a manner of expanding the outer diameter direction b in the direction connecting the two first protrusions 123, and the distance between the two first protrusions 123 becomes wider than the size of the photocatalyst filter 117, so that the photocatalyst filter 117 can be moved upward from the base 120 and removed. The removed photocatalyst filter 117 is cleaned.
在將清洗完成的光催化劑過濾器117或者所更換的新的光催化劑過濾器117安裝至支架118時，將光催化劑過濾器117從上方配置於底座部120的內側區域，並從上方按入，由此，一邊由光催化劑過濾器117在連結兩個第一突出部123的方向上朝外徑方向b擴寬，一邊使光催化劑過濾器117越過兩個第一突出部123，由此，光催化劑過濾器117被包夾在支承部122與第一突出部123之間而受到保持。光催化劑過濾器117的周面與兩個第二突出部125相向，且與兩個第三突出部127抵接而受到保持，光催化劑過濾器117的水平方向的晃動得到抑制。When the cleaned photocatalyst filter 117 or the replaced new photocatalyst filter 117 is installed on the bracket 118, the photocatalyst filter 117 is arranged on the inner area of the base portion 120 from above and pressed in from above, thereby, the photocatalyst filter 117 is widened toward the outer diameter direction b in the direction connecting the two first protrusions 123, and the photocatalyst filter 117 is passed over the two first protrusions 123, thereby, the photocatalyst filter 117 is sandwiched between the support portion 122 and the first protrusions 123 and is retained. The peripheral surface of the photocatalyst filter 117 faces the two second protrusions 125 and is held in contact with the two third protrusions 127 , so that the photocatalyst filter 117 is prevented from shaking in the horizontal direction.
在將裝配好的光催化劑過濾器單元79安裝至內部框體75時，將支架118的兩個安裝部121的豎立部129卡合至內部框體75的兩個支架安裝部89的凹陷部90，將底座部120從上方***至內部框體75的筒狀部86的內側。在此***過程中，引導凸肋131接觸至支架安裝部89的凹陷部90而兩個安裝部121以接近的方式發生彈性變形後，引導凸肋131的上部側的爪部132卡合至安裝孔91，並且安裝部121的手指鉤扣部130卡合至支架安裝部89的上側，從而安裝至內部框體75的筒狀部86。When the assembled photocatalyst filter unit 79 is mounted to the inner frame 75, the vertical portions 129 of the two mounting portions 121 of the bracket 118 are engaged with the recessed portions 90 of the two bracket mounting portions 89 of the inner frame 75, and the base portion 120 is inserted from above into the inner side of the cylindrical portion 86 of the inner frame 75. During this insertion process, the guide rib 131 contacts the recessed portion 90 of the bracket mounting portion 89, and the two mounting portions 121 are elastically deformed in a close manner, and then the claw portion 132 on the upper side of the guide rib 131 is engaged with the mounting hole 91, and the finger hook portion 130 of the mounting portion 121 is engaged with the upper side of the bracket mounting portion 89, so that it is mounted to the cylindrical portion 86 of the inner frame 75.
而且，在去除由拆卸的處理單元17的灰塵過濾器77所捕獲的灰塵時，從內部框體75拆卸可見光光源單元76。將可見光光源單元76的安裝構件99的兩個安裝爪部108按向中央側而從內部框體75的安裝孔94拆下，由此，能夠從內部框體75拆卸可見光光源單元76。所拆卸的可見光光源單元76在仍連接著與內部框體75側之間的可見光光源用的配線的狀態下從內部框體75朝橫向挪開，從而使灰塵過濾器77露出，利用吸塵器等來吸取去除灰塵。在灰塵的去除後，將可見光光源單元76的安裝構件99的兩個安裝爪部108按入至內部框體75的兩個安裝孔94而使其卡合，由此將可見光光源單元76安裝至內部框體75。另外，對於灰塵過濾器77的清掃，即便在處理單元17被安裝於本體單元16的狀態下，也能夠通過拆卸可見光光源單元76來實施。When removing dust captured by the dust filter 77 of the disassembled processing unit 17, the visible light source unit 76 is disassembled from the inner frame 75. The two mounting claws 108 of the mounting member 99 of the visible light source unit 76 are pressed toward the center side and removed from the mounting hole 94 of the inner frame 75, thereby enabling the visible light source unit 76 to be disassembled from the inner frame 75. The disassembled visible light source unit 76 is moved laterally from the inner frame 75 while still being connected to the wiring for the visible light source between the sides of the inner frame 75, thereby exposing the dust filter 77, and removing the dust by suction using a vacuum cleaner or the like. After the dust is removed, the two mounting claws 108 of the mounting member 99 of the visible light source unit 76 are pressed into the two mounting holes 94 of the inner frame 75 to engage the two mounting claws, thereby mounting the visible light source unit 76 to the inner frame 75. In addition, the dust filter 77 can be cleaned by disassembling the visible light source unit 76 even when the processing unit 17 is mounted on the main unit 16.
而且，在將所拆卸的處理單元17安裝至本體單元16時，從本體單元16內拿著連接器43而將配線44引出至下方，在本體單元16的下方，將連接器43連接至處理單元17的連接器92。按壓構件45的臂部47與所引出的配線44一同克服施力而朝下方擺動。When the disassembled processing unit 17 is mounted on the main body unit 16, the wiring 44 is led out downward while holding the connector 43 from the main body unit 16, and the connector 43 is connected to the connector 92 of the processing unit 17 at the bottom of the main body unit 16. The arm 47 of the pressing member 45 and the led wiring 44 overcome the applied force and swing downward.
使處理單元17的裝卸標記95對準本體單元16的裝卸標記59a的位置而將處理單元17***至本體單元16。若處理單元17相對於本體單元16的***位置正確，則處理單元17的裝卸引導部97能夠插通本體單元16的裝卸槽部56而將處理單元17***至本體單元16內的最裡側位置為止。另一方面，若處理單元17相對於本體單元16的***位置不正確，則處理單元17的裝卸引導部97未對準本體單元16的裝卸槽部56的位置，而無法將處理單元17***至本體單元16內的最裡側位置為止，而成為處理單元17的下部側突出至本體單元16的下方的狀態。也可在此狀態下使處理單元17轉動，使處理單元17的裝卸引導部97對準本體單元16的裝卸槽部56而插通。The processing unit 17 is inserted into the main body unit 16 by aligning the loading and unloading mark 95 of the processing unit 17 with the position of the loading and unloading mark 59a of the main body unit 16. If the insertion position of the processing unit 17 relative to the main body unit 16 is correct, the loading and unloading guide 97 of the processing unit 17 can be inserted through the loading and unloading groove 56 of the main body unit 16 and the processing unit 17 can be inserted to the innermost position in the main body unit 16. On the other hand, if the insertion position of the processing unit 17 relative to the main body unit 16 is incorrect, the loading and unloading guide 97 of the processing unit 17 is not aligned with the position of the loading and unloading groove 56 of the main body unit 16, and the processing unit 17 cannot be inserted to the innermost position in the main body unit 16, and the lower side of the processing unit 17 is protruded below the main body unit 16. In this state, the processing unit 17 may be rotated so that the attachment and detachment guide portion 97 of the processing unit 17 is aligned with the attachment and detachment groove portion 56 of the main body unit 16 and inserted therethrough.
當將處理單元17***至本體單元16內時，配線44將產生鬆弛，但通過按壓構件45的施力，由臂部47將配線44上提至上方，並且朝向外部框體24的內側面按壓，由此能夠防止配線44纏住或卡掛。When the processing unit 17 is inserted into the main unit 16, the wiring 44 will become loose, but through the force of the pressing member 45, the arm 47 will lift the wiring 44 upward and press it toward the inner side of the external frame 24, thereby preventing the wiring 44 from being entangled or stuck.
當將處理單元17***至本體單元16內的最裡側位置為止時，處理單元17的定位部96抵接於本體單元16的定位部58的***定位部58b而定位。在此狀態下，處理單元17的卡合部87位於本體單元16的支撐部66的防脫部67的上方。When the processing unit 17 is inserted to the innermost position in the body unit 16, the positioning portion 96 of the processing unit 17 abuts against the insertion positioning portion 58b of the positioning portion 58 of the body unit 16 and is positioned. In this state, the engaging portion 87 of the processing unit 17 is located above the anti-detachment portion 67 of the supporting portion 66 of the body unit 16.
使處理單元17朝安裝方向（仰視時為順時針方向）轉動，以使處理單元17的裝卸標記95從本體單元16的裝卸標記59a的位置移動至安裝標記59b的位置。由此，處理單元17的卡合部87移動至本體單元16的支撐部66上，裝卸引導部97從裝卸槽部56移動至安裝槽部57。處理單元17朝向安裝方向的轉動通過卡合部87抵接於支撐部66的與開口側為相反的側壁以及裝卸引導部97的擋塊部97b抵接於安裝槽部57的下部側的側壁而被限制在規定的安裝位置。The processing unit 17 is rotated in the installation direction (clockwise when viewed from below) so that the attachment mark 95 of the processing unit 17 moves from the position of the attachment mark 59a of the main body unit 16 to the position of the installation mark 59b. As a result, the engaging portion 87 of the processing unit 17 moves to the support portion 66 of the main body unit 16, and the attachment guide portion 97 moves from the attachment groove portion 56 to the installation groove portion 57. The rotation of the processing unit 17 in the installation direction is restricted to a predetermined installation position by the engaging portion 87 abutting against the side wall of the support portion 66 opposite to the opening side and the stopper portion 97b of the attachment guide portion 97 abutting against the side wall of the lower side of the installation groove portion 57.
通過解除處理單元17的上推，處理單元17的卡合部87被載放支撐於本體單元16的支撐部66上，並通過防脫部67防止從支撐部66上脫離。By releasing the push-up of the processing unit 17 , the engaging portion 87 of the processing unit 17 is placed and supported on the supporting portion 66 of the main body unit 16 , and is prevented from being separated from the supporting portion 66 by the anti-separation portion 67 .
當將處理單元17安裝至規定的安裝位置時，裝卸引導部97移動至安裝槽部57的位置而將安裝探測開關73接通，探測處理單元17的安裝狀態。因此，控制基板27的控制電路能夠進行對風扇25或紫外線光源單元78側的電力供給。When the processing unit 17 is installed at a predetermined installation position, the installation guide 97 moves to the position of the installation groove 57 and turns on the installation detection switch 73 to detect the installation state of the processing unit 17. Therefore, the control circuit of the control substrate 27 can supply power to the fan 25 or the ultraviolet light source unit 78 side.
而且，通過按壓構件45的施力，由臂部47將配線44上提至上方，並且朝向外部框體24的內側面按壓，由此減輕配線44的鬆弛。因此，即便配線44配置在流路22中，也能夠減輕因空氣的流動導致配線44移動而纏住或者妨礙流路22的空氣流動的現象。Furthermore, by the force of the pressing member 45, the arm 47 lifts the wiring 44 upward and presses it toward the inner side surface of the outer frame 24, thereby reducing the slack of the wiring 44. Therefore, even if the wiring 44 is arranged in the flow path 22, the phenomenon that the wiring 44 moves due to the flow of air and entangles or hinders the flow of air in the flow path 22 can be reduced.
這樣，本實施方式的空氣處理裝置10中，在設置時露出於房間的下部區域11b，呈圓周狀地設有進氣口18（第一口18a），並且在比進氣口18更靠外側呈圓周狀地設有排氣口19（第二口19a），利用流路22來連接這些進氣口18與排氣口19，在所述流路22上且比進氣口18更靠上側設有空氣處理部20，在所述空氣處理部20中具有朝向上方照射紫外線的紫外線光源110與位於所述紫外線光源110上方的光催化劑過濾器117，由此能夠抑制朝向房間的突出，切實地進行空氣處理。Thus, in the air treatment device 10 of the present embodiment, the lower area 11b exposed to the room when installed has air inlets 18 (first ports 18a) arranged in a circular shape, and air exhaust ports 19 (second ports 19a) arranged in a circular shape on the outer side than the air inlets 18, and the flow path 22 is used to connect these air inlets 18 and exhaust ports 19, and an air treatment section 20 is arranged on the flow path 22 and on the upper side than the air inlet 18, and the air treatment section 20 has an ultraviolet light source 110 for irradiating ultraviolet rays upward and a photocatalyst filter 117 located above the ultraviolet light source 110, thereby being able to suppress protrusion toward the room and effectively perform air treatment.
在流路22上且比空氣處理部20更靠上方包括風扇25，在進入風扇25之前的流路22的一部分與進入風扇25之後的流路22的一部分中，存在空氣的流動方向相差180度的區域，由此能夠抑制朝向房間的突出，切實地進行空氣處理。A fan 25 is included on the flow path 22 and above the air treatment unit 20. In a portion of the flow path 22 before entering the fan 25 and a portion of the flow path 22 after entering the fan 25, there is an area where the air flow direction differs by 180 degrees, thereby suppressing protrusion into the room and effectively performing air treatment.
另外，空氣處理裝置10也可為不包括可見光光源單元76的結構。此時，由於配設可見光光源單元76的位置成為空洞，因此也可構成為，利用規定的構件來封閉所述空洞。而且，也可取代可見光光源單元76而配置其他的功能零件。此處的其他的功能零件例如是指顯示器、揚聲器、投影機、發出香味的香氛等。In addition, the air treatment device 10 may also be a structure that does not include the visible light source unit 76. In this case, since the position where the visible light source unit 76 is arranged becomes a hollow, it may also be configured so that the hollow is sealed by a predetermined component. In addition, other functional parts may be arranged instead of the visible light source unit 76. The other functional parts here refer to, for example, a display, a speaker, a projector, a fragrance that emits a fragrance, etc.
