專利文獻1：日本特開平2-245212號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2-245212
上述的習知的空氣清淨機係構成為，藉由使得配置於空氣清淨機之本體前面的吸氣口朝向有人存在的方向，而積極吸入人周圍的空氣以進行清浄化。但是，被吸入空氣清淨機之空氣的風速比空氣清淨機所吹出的空氣之風速還要慢。因此，光靠著將吸氣口朝向人存在的方向之吸氣方向控制，可能 無法將人周圍空氣有效率地吸入。另外，在上述的習知技術中，因為沒有考慮到從空氣清淨機吹出的吹出風之方向，所以可能會有吹出風直接吹到人而造成人的不快感的情況。 The above-described conventional air cleaner is configured to actively inhale the air around the person to purify the air by causing the intake port disposed in front of the body of the air cleaner to face the direction in which the person is present. However, the air speed of the air sucked into the air cleaner is slower than the wind speed of the air blown by the air cleaner. Therefore, the light is controlled by the suction direction that directs the suction port toward the direction in which the person is present, possibly It is impossible to inhale the air around the person efficiently. Further, in the above-described conventional technique, since the direction of the blown air blown from the air cleaner is not taken into consideration, there is a possibility that the blown air is directly blown to the person to cause a person's unpleasant feeling.
本發明係為了解決如上述的問題，其目的在於提供空氣清淨機，其不會帶給室內的人不快感，並且可以有效率地將人周圍的空氣加以清淨化。 The present invention has been made in order to solve the above problems, and an object thereof is to provide an air cleaner which does not bring a feeling of discomfort to a person inside the room, and can efficiently purify the air around the person.

The control device has a wind direction control function that is controlled such that when a person in the room is detected by the person detecting device, the front-rear direction component of the wind direction vector at the maximum wind speed of the wind direction faces the direction of the person, the wind direction vector The total vector of omnidirectional components is oriented in the direction of no one.
依據本發明，當檢出在室內的人時，係控制為使得風向的最大風速處之風向向量的前後方向成分朝向有人的方向，風向向量的全方向成分之合計向量則朝向沒有人的方向。藉此，不會帶給室內的人不快感，並且可以有效率地將人周圍的空氣加以清淨化。 According to the present invention, when a person indoors is detected, it is controlled such that the front-rear direction component of the wind direction vector at the maximum wind speed in the wind direction faces the direction of the person, and the total vector of the omnidirectional components of the wind direction vector faces the direction in which no one is present. In this way, people in the room are not unpleasant, and the air around the person can be cleaned efficiently.

In the drawings, the same or corresponding components are designated by the same reference numerals, and the repeated description is omitted or omitted as appropriate. The present invention is not limited to the embodiments described below, and various modifications can be made without departing from the spirit and scope of the invention.
實施形態1 Embodiment 1
首先，參照第1圖到第7圖，說明本發明的實施形態1。第1圖顯示本發明實施形態1的空氣清淨機的立體圖。另外，第2圖第1圖中空氣清淨機的縱剖面圖。如這些圖所示，本實施形態中，係構成為地面設置型的空氣清淨機1。空氣清淨機1包括： 殼體2、基座3、吸入口4、吹出口5、送風裝置6、風路7A，7B、清淨化裝置8、可動柵板9、柵板驅動部10、開口可變機構11、開口驅動部12、整流機構13、整流驅動部14、水平回轉機構15等。 First, a first embodiment of the present invention will be described with reference to Figs. 1 to 7 . Fig. 1 is a perspective view showing an air cleaner according to a first embodiment of the present invention. In addition, Fig. 2 is a longitudinal sectional view of the air cleaner in Fig. 1 . As shown in these figures, in the present embodiment, the air cleaner 1 of the floor-mounted type is configured. The air cleaner 1 includes: Housing 2, base 3, suction port 4, air outlet 5, air blowing device 6, air path 7A, 7B, cleaning device 8, movable grid 9, grid drive unit 10, opening variable mechanism 11, opening drive The portion 12, the rectifying mechanism 13, the rectifying drive unit 14, the horizontal turning mechanism 15, and the like.
殼體2形成為例如略四角形的角筒形狀，藉由設置於房間地面的基座3，將其支持於可在水平方向回轉的狀態。如第2圖所示，在殼體2的內部空間中，在從吸入口4到吹出口5的空間中，從上游到朝向下游依序配置清淨化裝置8、送風裝置6、風路7。另外，在下文的說明中，殼體2的側面部當中，將主要面對室內空間配置的部分記述為前面部，將和前面部相對的部分記述為後面部。另外，殼體2的前面部側的方向記述為前方，從前方觀看之殼體2的水平方向的兩側則記述為左右方向，而且依據情況而將鉛直方向記述為上下方向。空氣清淨機1，設置在例如地面上靠近房間的任何一個壁面的位置，在殼體2的後面部朝向該壁面且殼體2的前面部朝向室內空間的狀態下使用。 The casing 2 is formed in a rectangular shape of, for example, a substantially square shape, and is supported by a base 3 provided on the floor of the room to be rotatable in a horizontal direction. As shown in Fig. 2, in the internal space of the casing 2, in the space from the suction port 4 to the air outlet 5, the cleaning device 8, the air blowing device 6, and the air path 7 are disposed in order from the upstream to the downstream. In the following description, among the side surface portions of the casing 2, a portion mainly disposed to face the indoor space is referred to as a front portion, and a portion facing the front portion is referred to as a rear portion. In addition, the direction of the front side of the casing 2 is described as the front side, and both sides of the casing 2 in the horizontal direction as viewed from the front are described as the left-right direction, and the vertical direction is described as the vertical direction depending on the case. The air cleaner 1 is installed, for example, at a position close to any one of the wall surfaces of the room, and is used in a state where the rear surface of the casing 2 faces the wall surface and the front portion of the casing 2 faces the indoor space.
吸入口4為，用以將室內空氣吸入殼體2內部的開口部，設置於例如殼體2的前面部。吹出口5為，用以將吸入殼體2內部的空氣吹出到外部的開口部，其由例如開口於殼體2的上面部的2個吹出口5A及5B所構成。2個吹出口5A及5B沿著殼體2的左右方互相並排延伸。另外，在後述說明中，在不特別區分吹出口5A及5B時，有時將之記述為「吹出口5」。另外，有時將從吹出口5吹出的空氣記述為「吹出空氣」。另外，在第2圖中顯示吹出空氣的最大風速處的風向向量50。由風向向量 50鉛直方向向量50a、前後方向向量50b、及圖未顯示的左右方向向量50c合成而成。另外，第2圖的情況為吹出口5A、5B的吹出空氣被合成，所以雖然風向向量50顯示為一個，但在吹出口5A、5B分別有風向向量50存在。另外，在本發明中，可以將吸入口4配置於殼體2的背面部、側面部、下面部等，也可以將吹出口5配置在殼體2的前面部、側面部等。再者，在殼體2中，可以僅配置1個吹出口5，也可以配置3個以上的吹出口5。亦即，吹出口5的位置或個數並不以實施形態1為限。 The suction port 4 is an opening for sucking indoor air into the inside of the casing 2, and is provided, for example, at a front surface portion of the casing 2. The air outlet 5 is an opening for blowing air that has entered the inside of the casing 2 to the outside, and is constituted by, for example, two air outlets 5A and 5B that are opened to the upper surface portion of the casing 2. The two air outlets 5A and 5B extend side by side along the left and right sides of the casing 2. In the following description, when the air outlets 5A and 5B are not particularly distinguished, they may be described as "the air outlet 5". Further, the air blown out from the air outlet 5 may be described as "blowing air". Further, in Fig. 2, the wind direction vector 50 at the maximum wind speed at which the air is blown is shown. Wind direction vector 50 vertical direction vector 50a, front and rear direction vector 50b, and left and right direction vector 50c not shown in the figure are combined. In the case of Fig. 2, the blown air of the air outlets 5A and 5B is combined. Therefore, although the wind direction vector 50 is shown as one, the wind direction vectors 50 exist in the air outlets 5A and 5B, respectively. Further, in the present invention, the suction port 4 may be disposed on the back surface portion, the side surface portion, the lower surface portion, or the like of the casing 2, or the air outlet 5 may be disposed in the front surface portion, the side surface portion, or the like of the casing 2. Further, in the casing 2, only one air outlet 5 may be disposed, or three or more air outlets 5 may be disposed. That is, the position or the number of the air outlets 5 is not limited to the first embodiment.
送風裝置6為，將空氣從吸入口4吸入殼體2內部並將該空氣從吹出口5吹出的裝置，其包括作為裝置本體部分的風扇6A、以及使風扇6A回轉的電動式馬達6B。風扇6A的回轉數由控制裝置23所控制。吹出空氣之風量對應於該回轉數而改變。在殼體2的內部如第2圖所示，例如2個的送風裝置6在上下方向並列配置於前後方向位置錯開的狀態下。 The air blowing device 6 is a device that sucks air from the suction port 4 into the casing 2 and blows the air out of the air outlet 5, and includes a fan 6A as a device body portion and an electric motor 6B that rotates the fan 6A. The number of revolutions of the fan 6A is controlled by the control unit 23. The amount of air blown out of the air changes corresponding to the number of revolutions. As shown in FIG. 2, for example, in the inside of the casing 2, for example, two air blowing devices 6 are arranged side by side in the vertical direction in a state in which the positions in the front-rear direction are shifted.
另外，在殼體2的內部，設有風路7，其連接送風裝置6及吹出口5，將從送風裝置6吹出的空氣導向吹出口5。風路7由設置於殼體2的隔壁2A而分隔為前面側的風路7A及背面側的風路7B。2個風路7A及7B，其配置為在殼體2的內部於上下方向延伸，例如從水平剖面觀看時於前後方向並列。 Further, inside the casing 2, an air passage 7 is provided which is connected to the air blowing device 6 and the air outlet 5, and guides the air blown from the air blowing device 6 to the air outlet 5. The air passage 7 is partitioned between the air passage 7A on the front side and the air passage 7B on the back side by the partition wall 2A provided in the casing 2. The two air passages 7A and 7B are arranged to extend in the vertical direction inside the casing 2, for example, in the front-rear direction when viewed from a horizontal cross section.
風路7A，7B的下部側分別與不同的送風裝置6連接，風路7A，7B的上部側則分別與吹出口5A，5B連接。亦即，空氣清淨機1具備：從一方的送風裝置6經過風路7A而到達吹出口5A的第1送風系統、以及從另一方的送風裝置6經過風路7B而到達吹出口5B的第2送風系統，在這些送風系統中，能夠個 別控制其風量、風向及風速。 The lower sides of the air passages 7A, 7B are respectively connected to different air blowing devices 6, and the upper sides of the air passages 7A, 7B are connected to the air outlets 5A, 5B, respectively. In other words, the air cleaner 1 includes the first air blowing system that has passed through the air path 7A from one of the air blowing devices 6 and reaches the air outlet 5A, and the second air blowing system that has passed through the air path 7B from the other air blowing device 6 to reach the air outlet 5B. Air supply system, in these air supply systems, can Do not control its air volume, wind direction and wind speed.
如上述，在實施形態1中，於殼體2的內部配置隔壁2A，在前後方向並列形成2個風路7A及7B。另外，2個送風裝置6當中，至少第2圖中位於上側之一方的送風裝置6，由馬達6B的一部埋在風扇6A的內部之馬達內建型的送風裝置所構成。藉此，在殼體2的內部有效率地形成2個送風系統，同時能夠使空氣清淨機1的設置面積小型化，而能夠實現小型且高性能的空氣清淨機1。 As described above, in the first embodiment, the partition wall 2A is disposed inside the casing 2, and the two air passages 7A and 7B are formed in parallel in the front-rear direction. Further, among the two air blowing devices 6, at least one of the air blowing devices 6 located on the upper side in the second drawing is constituted by a motor built-in air blowing device in which a part of the motor 6B is buried inside the fan 6A. Thereby, two air blowing systems are efficiently formed in the inside of the casing 2, and the installation area of the air cleaner 1 can be reduced, and the air cleaner 1 of a small size and high performance can be implement|achieved.
清淨化裝置8為，將通過殼體2內部的空氣清淨化的裝置，其設置於例如吸入口4和送風裝置6之間。在此，所謂的「清淨化」為，將例如浮游在空氣中的塵埃、煙、花粉、病毒、細菌、霉菌、過敏原、臭氣分子等構成的污染物質去除之意，具體言之，其係意味捕集這些污染物質，使其不活化，吸附及分解的動作。本實施形態的清淨化裝置8為可以進行此種清淨化程序的裝置，可以由下列機器構成或由下列機器組合而成：捕集空氣中塵埃的集塵濾器、捕捉空氣中的臭氣分子的脫臭濾器、在電極間產生高電場或放電生成物以去除污染物質的電壓施加裝置等。另外，在第4圖中係設想為電壓施加裝置，並顯示為清淨化裝置8與控制裝置23電性連接並受其控制。但是，清淨化裝置8一般係由脫臭濾器或集塵濾器等無法電性控制的部材所構成，清淨化裝置8並不一定要和控制裝置23電性連接，清淨化裝置8並不限於被控制裝置23所控制。本說明書並不限定清淨化裝置8為電性控制的裝置，亦不限定於由控制裝置23所控制。基本上只要具有以捕集、不活化、分解等的手 段將污染空氣的任何物質予以浄化之功能，即屬於清淨化裝置8的範圍。 The cleaning device 8 is a device for purifying the air passing through the inside of the casing 2, and is provided between, for example, the suction port 4 and the air blowing device 6. Here, the term "clear purification" means to remove pollutants such as dust, smoke, pollen, viruses, bacteria, molds, allergens, and odor molecules floating in the air, specifically, It means the action of trapping these pollutants so that they do not activate, adsorb and decompose.

In addition, in this specification, the "elevation angle" means an angle which is inclined upwards with respect to the horizontal direction parallel to the ground. That is, the elevation angle = 0° means that the horizontal direction and the elevation angle = 90° indicate directly above the vertical direction.
柵板驅動部10具有：以可擺動的方式支持可動柵板9的支軸、以及使該支軸回轉的致動器(圖未顯示)。可動柵板9和柵板驅動部10構成風向可變機構的具體例，其能夠將吹出空氣的風向在上下方向變化。如第2圖所示，開口可變機構11為，設置為在前後方向和其中一片可動柵板9相對的位置，和該可動柵板9協同動作以改變吹出口5A的開口面積的裝置。另外，在第1及3圖中，為了明確顯示後述的整流機構13，而省略了開口可變機構11的圖示。另外，在第2圖中，雖係例示將開口可變機構11僅配置於其中一個吹出口5A的情況，但本發明並不以此為限，也可以將開口可變機構11僅配置在另一方的吹出口5B，或者設置吹出口5A及5B雙方。 The grid drive unit 10 has a support shaft that rotatably supports the movable grid plate 9, and an actuator that rotates the support shaft (not shown). The movable grid plate 9 and the grid drive unit 10 constitute a specific example of the wind direction variable mechanism, which is capable of changing the wind direction of the blown air in the vertical direction. As shown in Fig. 2, the opening variable mechanism 11 is provided in such a position as to face the movable grid 9 in the front-rear direction, and the movable grid 9 cooperates to change the opening area of the air outlet 5A. In addition, in the first and third figures, in order to clearly show the rectifying mechanism 13 to be described later, the illustration of the opening variable mechanism 11 is omitted. In addition, in the second drawing, the case where the opening variable mechanism 11 is disposed only in one of the air outlets 5A is exemplified, but the present invention is not limited thereto, and the opening variable mechanism 11 may be disposed only in the other. One of the air outlets 5B or one of the air outlets 5A and 5B is provided.
開口可變機構11係由例如在殼體2的左右方向延伸的細長平板等形成。而且，開口可變機構11的基端側，透過與柵板驅動部10具有幾乎相同構成的開口驅動部12而安裝在吹出口5A上。開口可變機構11的尖端側可以藉由開口驅動部12而在前後方向擺動改變位置，以使其靠近及遠離可動柵板9。藉此，開口可變機構11可以增減吹出口5A的開口面積，並能夠使空氣的風速對應於該開口面積而改變。亦即，開口可變機構11及開口驅動部12為構成可改變吹出空氣之風速的送風改變 手段的具體例。另外，開口可變機構11，也可以不配置於吹出口5而配置於風路7A及7B中任一者或兩者，作為調整風路7的開口面積(亦即流路面積)的機構。 The opening variable mechanism 11 is formed of, for example, an elongated flat plate or the like that extends in the left-right direction of the casing 2. Further, the proximal end side of the opening variable mechanism 11 is attached to the air outlet 5A through the opening driving portion 12 having substantially the same configuration as the grid driving portion 10. The tip end side of the opening variable mechanism 11 can be swung in the front-rear direction by the opening driving portion 12 to change position so as to be close to and away from the movable grid 9. Thereby, the opening variable mechanism 11 can increase or decrease the opening area of the air outlet 5A, and can change the wind speed of the air corresponding to the opening area. That is, the opening variable mechanism 11 and the opening driving portion 12 constitute a supply air change that can change the wind speed of the blown air. Specific examples of means. Further, the opening variable mechanism 11 may be disposed in either or both of the air passages 7A and 7B without being disposed in the air outlet 5 as a mechanism for adjusting the opening area (that is, the flow path area) of the air passage 7.
整流機構13為，在維持由可動柵板9所設定的風向仰角的狀態下，於左右方向調整該風向的裝置。如第2及3圖所示，整流機構13形成為例如略三角形狀(或扇形狀)的鰭片形成，從各可動柵板9的受風面側突出，並在左右方向隔著間隔配置複數個整流機構13。而且，如第3圖(a)、(b)所示，各個整流機構13在左右方向擺動，使得吹出空氣的風向在左右方向對應於該擺動角而改變。 The rectifying mechanism 13 is a device that adjusts the wind direction in the left-right direction while maintaining the elevation angle of the wind set by the movable grille 9. As shown in the second and third figures, the rectifying mechanism 13 is formed, for example, in a substantially triangular shape (or a fan shape), and protrudes from the wind receiving surface side of each movable grille 9 and is disposed at intervals in the left-right direction. A rectifying mechanism 13. Further, as shown in FIGS. 3(a) and 3(b), each of the rectifying mechanisms 13 is swung in the left-right direction so that the wind direction of the blown air changes in the left-right direction corresponding to the swing angle.
另外，整流機構13的擺動動作，可以由例如設置在可動柵板9的整流驅動部14(僅在第4圖中顯示)執行。亦即，整流機構13及整流驅動部14，構成可以將吹出空氣的風向在左右方向上改變的風向可變機構的具體例。另外，在本發明中，並不一定要設置整流機構13。另外，也可以構成為，例如僅在可動柵板9的左右兩端側各配置1個整流機構13。 Further, the swing operation of the rectifying mechanism 13 can be performed, for example, by the rectifying drive unit 14 (shown only in Fig. 4) provided on the movable grid 9. In other words, the rectifying mechanism 13 and the rectifying drive unit 14 constitute a specific example of a variable direction mechanism that can change the wind direction of the blown air in the left-right direction. Further, in the present invention, it is not necessary to provide the rectifying mechanism 13. In addition, for example, only one rectifying mechanism 13 may be disposed on each of the right and left end sides of the movable grille plate 9.
如第1及2圖所示，水平回轉機構15為，設置於殼體2和基座3之間，使殼體2在基座3上至少於左右方向轉動的裝置。吹出口5的方向係連同殼體2一起在水平方向改變，所以水平回轉機構15構成能夠使吹出空氣的風向在左右方向改變的風向可變機構的具體例。另外，同樣地，吸入口4的方向也連同殼體2一起在水平方向改變，所以水平回轉機構15構成使吸入口4在水平方向回轉之吸入口水平回轉機構的具體例。另外，如上所述，本實施形態1，係為將2個風扇在上下方向並列 的構造，藉此使得其相較於以1個風扇驅動的同風量之裝置更容易成型為正方形或圓形，而使得其設置面積小型化。尤其是，正方形或圓形使得在水平方向進行回轉動作時所必須的設置面積也小型化，因此為使水平回轉機構15運作時的最佳形狀。藉此，即使有水平回轉機構15，也能夠容易地設置在家具等之間，並讓使用者因應房間的狀況而自由配置，實現具有泛用性的構成。 As shown in FIGS. 1 and 2, the horizontal turning mechanism 15 is a device that is provided between the casing 2 and the susceptor 3 to rotate the casing 2 on the susceptor 3 at least in the left-right direction. Since the direction of the air outlet 5 is changed in the horizontal direction together with the casing 2, the horizontal turning mechanism 15 constitutes a specific example of a variable direction mechanism that can change the wind direction of the blown air in the left-right direction. Further, similarly, the direction of the suction port 4 is also changed in the horizontal direction together with the casing 2. Therefore, the horizontal turning mechanism 15 constitutes a specific example of the suction port horizontal turning mechanism that rotates the suction port 4 in the horizontal direction. Further, as described above, in the first embodiment, the two fans are juxtaposed in the vertical direction. The configuration is such that it is easier to form a square or a circle than a device driven by a fan with the same air volume, so that the installation area is miniaturized. In particular, the square or the circular shape also makes the installation area necessary for the turning operation in the horizontal direction small, so that the horizontal swing mechanism 15 is optimally operated. As a result, even if the horizontal swing mechanism 15 is provided, it can be easily installed between furniture and the like, and the user can freely arrange in accordance with the situation of the room, thereby realizing a configuration having versatility.

(人檢出裝置的構成) (Composition of human detection device)
繼之，參照第5圖到第7圖，說明人檢出裝置21的構成。第5圖顯示紅外線檢測器的構造之模型剖面圖。第6圖顯示紅外線檢測器之各受光元件的配置及配光視野角的立體圖。第7圖顯 示包含紅外線檢測器外部檢出裝置的回轉動作(a)，(b)，(c)的說明圖。如上述，人檢出裝置21具有紅外線檢測器40及檢測器動作部44。紅外線檢測器40係為檢出從檢出對象物產生的紅外線，如第5圖所示，其具有由複數個受光元件41a~41h所構成的多元件受光單元41、及集光透鏡42。另外，在第5圖中，係例示由8個受光元件41a~41h構成多元件受光單元41的情況。不過，在本發明中，受光元件的個數並不限定於8個，多元件受光單元41可以由7個以下或9個以上的任意個數之受光元件所構成。 Next, the configuration of the person detecting device 21 will be described with reference to FIGS. 5 to 7. Fig. 5 is a cross-sectional view showing the structure of the infrared detector. Fig. 6 is a perspective view showing the arrangement of the light receiving elements of the infrared detector and the viewing angle of the light distribution. Figure 7 shows An explanatory diagram including the turning operations (a), (b), and (c) of the infrared detector external detecting device is shown. As described above, the person detecting device 21 includes the infrared ray detector 40 and the detector operating unit 44. The infrared ray detector 40 detects infrared rays generated from the detection target, and has a multi-element light-receiving unit 41 composed of a plurality of light-receiving elements 41a to 41h and a collecting lens 42 as shown in FIG. In addition, in the fifth drawing, the case where the multi-element light receiving unit 41 is constituted by the eight light receiving elements 41a to 41h is exemplified. However, in the present invention, the number of light receiving elements is not limited to eight, and the multi-element light receiving unit 41 may be composed of seven or less or nine or more arbitrary number of light receiving elements.
各受光元件41a~41h，係為可以個別執行紅外線受光及人之檢出的檢出元件，其配置為例如在上下方向直線狀並列。藉此，紅外線檢測器40具備區分並檢出室內溫度高度彼此相異的8個區域之功能。集光透鏡42，係為使紅外線有效率地對多元件受光單元41進行集光的裝置，其係由例如凸透鏡構成。集光透鏡42可以配置於多元件受光單元41的Z方向上部。紅外線檢測器40，由各個受光元件41a~41h以檢出檢出對象物的溫度，輸出對應於例如室內熱影像資料的信號。 Each of the light-receiving elements 41a to 41h is a detection element that can individually perform infrared light reception and human detection, and is arranged, for example, in a straight line in the vertical direction. Thereby, the infrared ray detector 40 has a function of distinguishing and detecting eight regions in which the indoor temperature heights are different from each other. The collecting lens 42 is a device that efficiently collects infrared light into the multi-element light receiving unit 41, and is configured by, for example, a convex lens. The collecting lens 42 can be disposed in the upper portion of the multi-element light receiving unit 41 in the Z direction. The infrared ray detector 40 detects the temperature of the detected object by the respective light receiving elements 41a to 41h, and outputs a signal corresponding to, for example, indoor thermal image data.
第6圖顯示紅外線檢測器之各受光元件的配置及配光視野角的立體圖。如此圖所示，各受光元件41a~41h之配光視野角43a~43h係設定為尺寸彼此相同的四角形狀的區域。另外，1個受光元件41a(亦可為41b~41h)的配光視野角43a(43b~43h)係設定為在例如上下方向之縱配光視野角為7°，並設定為左右方向的橫配光視野角為8°。 Fig. 6 is a perspective view showing the arrangement of the light receiving elements of the infrared detector and the viewing angle of the light distribution. As shown in the figure, the light distribution viewing angles 43a to 43h of the respective light receiving elements 41a to 41h are set to quadrangular regions having the same size. In addition, the light distribution viewing angles 43a (43b to 43h) of one light receiving element 41a (may be 41b to 41h) are set such that the vertical viewing angle of the vertical direction is, for example, 7°, and is set to the horizontal direction. The viewing angle of the light distribution is 8°.
配光視野角43a~43h合成的全體的配光視野角43 係設定為在上下方向為細長的區域，具有作為配光視野角43之上限的視野角上限43max、及作為配光視野角43的下限之視野角下限43min。另外，在本發明中，配光視野角43a~43h不必是相同形狀、相同尺寸，縱配光視野角及橫配光視野角之具體值也不限定於上記例示。 The total light distribution viewing angle 43 synthesized by the light distribution viewing angles 43a to 43h The area is elongated in the vertical direction, and has an upper limit of the viewing angle 43max which is the upper limit of the light distribution viewing angle 43 and a lower limit of the viewing angle of 43 min which is the lower limit of the light distribution viewing angle 43. Further, in the present invention, the light distribution viewing angles 43a to 43h are not necessarily the same shape and the same size, and the specific values of the vertical light distribution angle and the horizontal distribution light viewing angle are not limited to the above-described examples.
檢測器動作部44，係構成為能夠將紅外線檢測器40的方向在相對於殼體2的水平方向回轉。檢測器動作部44係使用例如能夠正確調整紅外線檢測器40的回轉驅動角度的步進馬達，其構成為可以獨立於上述水平回轉機構15的動作而控制。第7圖為表示檢測器動作部之紅外線檢測器的回轉動作之說明圖，(a)顯示向右端部回轉驅動的情況，(b)顯示向中央部回轉驅動的情況，(c)顯示向左端部回轉驅動的情況。如該圖所示，人檢出裝置21，首先由檢測器動作部44將紅外線檢測器40的方向(檢出方向)在左右方向上回轉驅動。更具體地說，紅外線檢測器40的方向，係被回轉驅動為從第7圖中(a)所示的右端部經由(b)所示的中央部後再到(c)所示的左端部。而且，當其到達(c)所示的左端部時，將回轉方向反轉，從(c)所示的左端部經由(b)所示的中央部再回到(a)所示的右端部。人檢出裝置21重複進行上述的動作，藉此在左右方向掃瞄室內的溫度檢出對象範圍並依序檢出其溫度。 The detector operation unit 44 is configured to be capable of rotating the direction of the infrared ray detector 40 in the horizontal direction with respect to the casing 2. The detector operation unit 44 uses, for example, a stepping motor that can accurately adjust the swing driving angle of the infrared detector 40, and is configured to be controllable independently of the operation of the horizontal swing mechanism 15. Fig. 7 is an explanatory view showing a turning operation of the infrared detector of the detector operating portion, wherein (a) shows a case where the right end portion is rotationally driven, (b) a case where the center portion is rotationally driven, and (c) a left end. The case of the partial slewing drive. As shown in the figure, the human detecting device 21 first drives the direction (detection direction) of the infrared detector 40 in the left-right direction by the detector operating unit 44. More specifically, the direction of the infrared ray detector 40 is rotationally driven from the right end portion shown in (a) of FIG. 7 to the left end portion shown by (c) through the center portion shown in (b). . Further, when it reaches the left end portion shown in (c), the rotation direction is reversed, and the left end portion shown in (c) is returned to the right end portion shown by (a) via the center portion shown in (b). . The human detecting device 21 repeats the above-described operation, thereby scanning the temperature detection target range in the room in the left-right direction and sequentially detecting the temperature thereof.
(人檢出控制) (person checkout control)
繼之，說明由控制裝置23執行的人檢出控制。控制裝置23，用人檢出裝置21取得室內的壁或地面的熱影像資料，並基於該熱影像資料在室內執行在室內之人的檢出。詳言之，首 先，控制裝置23，使檢測器動作部44可以在左右方向上以預設的可動角度(在此設定為1.6°)移動。藉此，以1.6°回轉驅動紅外線檢測器40。繼之，使紅外線檢測器40依預設的待機時間(例如0.1~0.2秒)停止。繼之，在此情間以紅外線檢測器40的8個受光元件41a~41h分別檢出熱影像資料，並輸入控制裝置23。經過待機時間之後，控制裝置23再度使檢測器動作部44在左右方向移動可動角度(1.6°)。然後，藉由和上述一樣的動作，將熱影像資料輸入控制裝置23。在94個位置每隔可動角度1.6°執行像這樣的處理。在此情況下，紅外線檢測器40之左右方向的可動範圍(亦即左右方向上回轉驅動的角度範圍)約為150.4°。 Next, the person detection control executed by the control device 23 will be described. The control device 23 obtains the thermal image data of the wall or the ground in the room by the human detecting device 21, and performs the detection of the person indoors indoors based on the thermal image data. In detail, the first First, the control unit 23 causes the detector operating unit 44 to move in the left-right direction at a predetermined movable angle (here set to 1.6°). Thereby, the infrared detector 40 is driven at a rotation of 1.6°. Next, the infrared detector 40 is stopped according to a preset standby time (for example, 0.1 to 0.2 seconds). Then, in this case, the thermal image data is detected by the eight light receiving elements 41a to 41h of the infrared ray detector 40, and is input to the control device 23. After the waiting time has elapsed, the control device 23 again moves the detector operating unit 44 to the movable angle (1.6°) in the left-right direction. Then, the thermal image data is input to the control device 23 by the same operation as described above. Such processing is performed at 94 positions at a movable angle of 1.6°. In this case, the movable range of the infrared detector 40 in the left-right direction (that is, the angular range of the slewing drive in the left-right direction) is about 150.4.
依據如上述的人檢出裝置21的構成，在紅外線檢測器40的左右方向之可動範圍中，在各時間比較熱影像資料，藉此能夠檢出在室內空間內出現的人的方向及高度。另外，依據本實施形態的人檢出裝置21，藉由紅外線檢測器40的8個受光元件41a~41h分別取得各配光視野角43a~43h之區域的熱影像資料，能夠依據在哪一個配光視野角的區域中檢出了人的存在而更精確檢出人體的高度。再者，控制裝置23係將檢測器動作部44和水平回轉機構15的動作獨立控制，所以，能夠使紅外線檢測器40的左右方向的方向回轉驅動而不會影響後述的風向控制。 According to the configuration of the human detecting device 21 as described above, the thermal image data is compared at each time in the movable range of the infrared detector 40 in the left-right direction, whereby the direction and height of the person appearing in the indoor space can be detected. Further, according to the human detecting device 21 of the present embodiment, the thermal image data of the respective light distribution viewing angles 43a to 43h are obtained by the eight light receiving elements 41a to 41h of the infrared ray detector 40, depending on which one is matched. The presence of a person is detected in the area of the light viewing angle to more accurately detect the height of the human body. Further, since the control device 23 independently controls the operations of the detector operating unit 44 and the horizontal turning mechanism 15, the direction of the infrared detector 40 in the horizontal direction can be rotationally driven without affecting the wind direction control to be described later.
另外，人檢出裝置21並不一定是由紅外線檢測器40所構成，只要是能夠檢出在室內的人之方向及其高度的檢測器即可，其可以由下列機器構成或由下列機器和紅外線檢測器40組合而成：髒污檢測器、動體檢測器、距離檢測器、濕度檢 測器、或照度檢測器等。 Further, the human detecting device 21 is not necessarily constituted by the infrared ray detector 40, and may be any detector that can detect the direction of the person in the room and its height, and may be constituted by the following machines or by the following machines and Infrared detector 40 is combined: dirt detector, dynamic detector, distance detector, humidity inspection Detector, or illuminance detector, etc.
髒污檢測器(塵埃檢測器)係由半導體元件、光學元件等構成，檢出在空氣中的塵埃、煙、花粉等的濃度。距離檢測器由超音波檢測器、光檢測器、影像辨識檢測器等的非接觸式的檢測器構成，其利用音波或電磁波，檢出空氣清淨機1和檢出對象物的距離。檢出對象物包含室內的牆壁、天花板、家具、人、動物等。照度檢測器基於照度的變化，而檢出在室內有沒有人及動物、以及有沒有動作等。另外，濕度檢測器的輸出，係用於對應濕度以修正上述各檢測器的感度。另外，上記各檢測器的組合僅為一例，本發明並不限定於上記各檢測器的組合而成的人檢出裝置。 The stain detector (dust detector) is composed of a semiconductor element, an optical element, or the like, and detects the concentration of dust, smoke, pollen, and the like in the air. The distance detector is composed of a non-contact type detector such as an ultrasonic detector, a photodetector, or a video recognition detector, and detects the distance between the air cleaner 1 and the detected object by using sound waves or electromagnetic waves. The detected object includes indoor walls, ceilings, furniture, people, animals, and the like. The illuminance detector detects whether there are people and animals in the room, and whether there is any action or the like based on the change in illuminance. In addition, the output of the humidity detector is used to correspond to the humidity to correct the sensitivity of each of the above detectors. Further, the combination of the above detectors is only an example, and the present invention is not limited to the human detecting device in which the respective detectors are combined.
(風向控制) (wind direction control)
繼之，說明由控制裝置23執行的風向控制。控制裝置23，基於人檢出裝置21的紅外線檢測器40所取得的熱影像資料，當判斷為室內有人的時候，執行風向控制。在風向控制中，首先，算出為使得空氣清淨機1的前面部朝向人的方向所必須的水平方向的回轉角度θ1。繼之，控制裝置23，藉由水平回轉機構15使殼體2依回轉角度θ1回轉。藉此，吹出口5為在水平方向上朝向有人的方向的狀態。另外，風向向量50當中至少前後方向向量50b為朝向人的方向的狀態。 Next, the wind direction control performed by the control device 23 will be described. The control device 23 performs wind direction control when it is determined that there is a person in the room based on the thermal image data acquired by the infrared detector 40 of the person detecting device 21. In the wind direction control, first, the rotation angle θ1 in the horizontal direction necessary for the front portion of the air cleaner 1 to face the person is calculated. Next, the control unit 23 rotates the casing 2 by the horizontal rotation mechanism 15 in accordance with the rotation angle θ1. Thereby, the air outlet 5 is in a state of facing the direction of a person in the horizontal direction. Further, at least the front-rear direction vector 50b among the wind direction vectors 50 is in a state of facing the direction of the person.
在後續的處理中，將上下方向之可動柵板9的仰角θ2(亦即風向的仰角θ2)設定為使得風向朝向比人的高度還要上方的送風區域。在此，例如在受光元件41a~41h當中，於受光元件41f~41h中檢知有人的情況下，以受光元件41a~41e的部 分作為送風區域。繼之，算出可以對此送風區域送風的可動柵板9之仰角θ2，並驅動可動柵板9。藉此，吹出風向著在室內的人的頭上送風。亦即風向向量50的鉛直方向向量50a設定為不朝向人，作為各向量成分50a、50b、50c之總和的風向向量50不朝向人的方向。另外，在此係使鉛直方向向量50a移動，同時使得前後方向向量50b朝向人的方向，以使得總和的風向向量50不朝向人，不過也可以改變左右方向向量50c，也可以改變50a及50c雙方。亦即，重點在於即使前後方向向量50b是朝向人的方向，風向向量50也不朝向人的方向。 In the subsequent processing, the elevation angle θ2 of the movable grid 9 in the vertical direction (that is, the elevation angle θ2 of the wind direction) is set such that the wind direction is directed to the air blowing region above the height of the person. Here, for example, in the case where the light receiving elements 41f to 41h detect a person among the light receiving elements 41a to 41h, the portions of the light receiving elements 41a to 41e are used. The minute is used as the air supply area. Next, the elevation angle θ2 of the movable grid 9 which can blow the air to the air blowing area is calculated, and the movable grid 9 is driven. Thereby, the wind is blown to the air of the person inside the room. That is, the vertical direction vector 50a of the wind direction vector 50 is set so as not to face the person, and the wind direction vector 50 which is the sum of the vector components 50a, 50b, and 50c does not face the direction of the person. In addition, the vertical direction vector 50a is moved here while the front-back direction vector 50b is oriented in the direction of the person such that the sum of the wind direction vectors 50 does not face the person, but the left-right direction vector 50c may be changed, or both 50a and 50c may be changed. . That is, the point is that even if the front-back direction vector 50b is the direction toward the person, the wind direction vector 50 does not face the direction of the person.
可動柵板9的仰角θ2，係可以使用各受光元件41a~41h當中已檢知人體之受光元件的個數(人體檢知元件數N)、以風量Q及風速V送風時的氣流的散開角度△θ2當中，下側的散開角度△θ2-(Q，V)、以及使視野角下限43min從水平向下方向傾斜的傾斜角θ3決定，其係依據公式(1)。 The elevation angle θ2 of the movable grid plate 9 can be used by using the number of light-receiving elements of the human body (the number of human detecting elements N) among the light-receiving elements 41a to 41h, and the angle of the airflow when the air is blown by the air volume Q and the wind speed V. Among Δθ2, the lower side spread angle Δθ2 - (Q, V) and the inclination angle θ3 which lowers the view angle lower limit 43min from the horizontal downward direction are determined according to the formula (1).
θ2≧7×N-θ3+△θ2-(Q，V)…(1) Θ2≧7×N-θ3+Δθ2 - (Q,V)...(1)
另外，在上述風向控制中，可動柵板9的仰角θ2可以作為上式(1)之右邊的值(固定值)，另外，也可以使其在上式(1)的右邊的值以上的範圍中變動，使可動柵板9在送風區域內搖擺。 Further, in the above-described wind direction control, the elevation angle θ2 of the movable grid plate 9 may be a value (fixed value) on the right side of the above formula (1), or may be in a range equal to or larger than the value on the right side of the above formula (1). The medium variation causes the movable grid 9 to sway in the air supply area.
另外，藉由上述風向控制向人的上方之送風區域進行送風的期間，控制裝置23，使用髒污檢出裝置20，持續檢出從吸入口4吸入之空氣的髒污程度。而且，控制裝置23，判斷所檢出的髒污程度是否在閾值以下。在此，閾值係使用預設的值，其係為表示空氣已被清浄之事實的髒污程度之閾值。其 結果為，當判斷為已檢出的髒污程度在閾值以下時，即能判斷為現在風向的區域之空氣已充分清浄化了，所以結束對該風向的風向控制。繼之，控制裝置23，藉由上述人檢出控制以判斷是否有與現在送風所朝向的人不同的人在室內。其結果為，判斷為在室內有與前回相異條件的人存在時，再以該相異條件的人為對象進行風向控制。藉此，能夠依序對於在室內的人之方向進行送風。 Further, while the wind direction is being controlled to blow air to the air blowing area above the person, the control device 23 uses the soil detecting device 20 to continuously detect the degree of contamination of the air taken in from the suction port 4. Further, the control device 23 determines whether or not the detected degree of contamination is below the threshold. Here, the threshold uses a preset value which is a threshold value indicating the degree of soiling of the fact that the air has been cleaned. its As a result, when it is determined that the detected degree of contamination is below the threshold value, it can be determined that the air in the region of the current wind direction has been sufficiently cleaned, so that the wind direction control of the wind direction is ended. Next, the control device 23 determines whether or not there is a person who is different from the person to whom the current air is directed, by the above-described person detection control. As a result, when it is determined that there is a person who has a condition different from the previous time in the room, the wind direction control is performed on the person with the different condition. Thereby, it is possible to sequentially supply air to the person in the room.
另一方面，當判斷為在室內沒有別人時，繼續送風同時驅動水平回轉機構15以改變吹出空氣的風向，藉由髒污檢出裝置20確認是否有被檢出大於閾值的髒污程度的風向。其結果為，有髒污程度大於閾值之值的風向時，進行第二風向控制，以朝向該風向重點式地進行吹出空氣送風。另一方面，當沒有檢出大於閾值的髒污程度的風向時，使空氣清淨機1的水平回轉機構15回到初期位置並進行降低風量的運轉。藉由進行此種控制，即使在室內沒有人的情況，也能夠重點式地將髒污程度大的區域之空氣清浄化。 On the other hand, when it is determined that there is no other person in the room, the air blowing is continued while the horizontal turning mechanism 15 is driven to change the wind direction of the blown air, and the dirt detecting device 20 confirms whether or not there is a wind direction in which the degree of contamination larger than the threshold is detected. . As a result, when there is a wind direction in which the degree of contamination is greater than the threshold value, the second wind direction control is performed, and air blowing is performed in a key manner toward the wind direction. On the other hand, when the wind direction of the dirtiness level larger than the threshold value is not detected, the horizontal swing mechanism 15 of the air cleaner 1 is returned to the initial position and the operation for reducing the air volume is performed. By performing such control, even if there is no person indoors, it is possible to cleanly clean the air in a region with a large degree of soiling.
不過，在上述的風向控制中，基於人檢出控制所檢出的在室之人的方向及人的高度以調整風向，同時也考慮到在室之人在室內移動的情況。因此，使人檢出控制持續動作，持續監視在室之人的移動，當在室之人移動時則據以改變風向控制的送風區域。另外，在室之人的數量在途中增加時，用髒污檢出裝置20檢出向各個人的方向送風時的髒污程度，從已檢出的髒污程度大的人之方向開始依序進行送風為佳。另外，當複數人聚集在一起時，可以將其視為人區域，針對人和人之間 送風，以將整個人區域一起進行空氣清淨。亦即，事先測定可以用吹送的風進行清浄化之範圍，以決定對應於人和人的距離感之送風條件，藉此，減少水平回轉的動作回數，而能夠進行減少浪費且效率良好的空氣清浄。藉此，當在室之人移動時，或者在室人數增加時，也能夠在不會造成在室之人的不快感的情況下，有效率地將人的周圍之空氣清浄化。 However, in the above-described wind direction control, the direction of the person in the room and the height of the person detected by the person detection control are adjusted to adjust the wind direction, and it is also considered that the person in the room moves indoors. Therefore, the person detection control is continuously operated, and the movement of the person in the room is continuously monitored, and when the person in the room moves, the air supply area controlled by the wind direction is changed accordingly. In addition, when the number of people in the room increases on the way, the dirt detecting device 20 detects the degree of soiling when the air is blown in the direction of each person, and starts from the direction of the person with a large degree of contamination detected. It is better to carry out the air supply. In addition, when multiple people gather together, they can be regarded as human areas, between people and people. Air is supplied to clean the entire area together. In other words, it is possible to measure the range of the airflow that can be cleaned by the blown wind in advance, thereby determining the airflow condition corresponding to the sense of distance between the person and the person, thereby reducing the number of operations of the horizontal swing, and reducing waste and efficiency. The air is clean. Thereby, when the person in the room moves, or when the number of people in the room increases, it is possible to efficiently purify the air around the person without causing an unpleasant feeling to the person in the room.
如上述，藉由本實施形態的空氣清淨機，能夠使得從吹出口5吹出的清浄空氣不直接吹到人且朝向人的方向送風。此時，因為吹出風是高速的，所以產生了從人所在的區域向空氣清淨機1的吸入口4的誘導氣流。另外，由於吹出風是已清浄過的空氣，所以也會產生因為和周圍的濃度梯度而造成的氣流。藉此，能夠抑制帶給人的被吹感，同時有效地將人所在區域的塵埃吸引到吸入口4以優先將人的周圍進行浄化。 As described above, according to the air cleaner of the present embodiment, the clean air blown from the air outlet 5 can be blown directly to the person and blown in the direction of the person. At this time, since the blown air is high speed, an induced airflow from the region where the person is present to the suction port 4 of the air cleaner 1 occurs. In addition, since the blown air is cleaned air, airflow due to the concentration gradient around it is also generated. Thereby, it is possible to suppress the feeling of being blown to the person while effectively sucking the dust of the area where the person is located to the suction port 4 to preferentially purify the surroundings of the person.
另外，藉由本實施形態的空氣清淨機，在風向控制中，藉由水平回轉機構15調整左右方向的風向，藉由可動柵板9調整上下方向的風向。藉此，能夠精確地進行風向控制，而能夠對在室之人穩定且持續地提供相同的效果。 Further, in the air cleaner of the present embodiment, in the wind direction control, the horizontal direction of the wind direction is adjusted by the horizontal turning mechanism 15, and the wind direction in the vertical direction is adjusted by the movable grid 9. Thereby, the wind direction control can be accurately performed, and the same effect can be stably and continuously provided to the person in the room.
另外，在風向控制中，藉由整流機構13在左右方向調整風向。不過，由整流機構13的風向調整難以向人的正上方精確地送風而容易發生左右方向的偏離。另外，整流機構13的風向調整，還有向左右端送風的壓力損失大的特徵。但是，整流機構13之控制應答性優於水平回轉機構15。因此，在左右方向的風向控制中，可以考慮這些機構彼此的優點而將各機構的動作適當的組合執行。 Further, in the wind direction control, the wind direction is adjusted in the left-right direction by the rectifying mechanism 13. However, it is difficult for the wind direction adjustment by the rectifying mechanism 13 to accurately blow the air directly above the person, and the horizontal direction is likely to be deviated. Further, the wind direction of the rectifying mechanism 13 is adjusted, and the pressure loss to the right and left ends is large. However, the control responsiveness of the rectifying mechanism 13 is superior to that of the horizontal slewing mechanism 15. Therefore, in the wind direction control in the left-right direction, the actions of the respective mechanisms can be appropriately combined in consideration of the advantages of these mechanisms.
另外，依據本實施形態的空氣清淨機，使整流機構13向左右個別的方向，藉此能夠產生向室內的左右方向散開的氣流。藉此，當有複數人在室內，且人所在區域大的情況下，也能向其頭上廣泛地送風。 Further, according to the air cleaner of the present embodiment, the rectifying mechanism 13 can be caused to flow in the left and right directions in the left and right directions in the room. Thereby, when a plurality of people are indoors and the area where the person is located is large, the wind can be widely supplied to the head.
另外，依據本實施形態的空氣清淨機，係構成為人檢出裝置21的人檢出控制和風向控制是個別動作。因此，能夠不改變風向而在廣範圍中檢知人。另外，風向控制執行中能夠持續監視人，所以能夠有彈性地應對人的動作。 Further, according to the air cleaner of the present embodiment, the person detection control and the wind direction control configured as the person detecting device 21 are individual operations. Therefore, it is possible to detect a person in a wide range without changing the wind direction. In addition, since the person can be continuously monitored during the execution of the wind direction control, it is possible to flexibly respond to the movement of the person.
另外，人檢出裝置21的檢出控制中，可以由檢測器動作部44將水平回轉機構15的殼體2回轉驅動與紅外線檢測器40回轉驅動組合。藉由此動作，能夠使紅外線檢測器40於兩軸上移動，能夠從不同的方向得到同一位置的影像。藉此，不僅取得在室之人的方向及其高度資訊，還能夠取得位置資訊，而可期更進一步提高風向控制的精度。 Further, in the detection control of the person detecting device 21, the detector operating unit 44 can rotatably drive the casing 2 of the horizontal turning mechanism 15 in combination with the infrared detector 40. By this operation, the infrared ray detector 40 can be moved on both axes, and images of the same position can be obtained from different directions. In this way, not only the direction of the person in the room and the height information thereof but also the position information can be obtained, and the accuracy of the wind direction control can be further improved.
另外，在本實施形態的空氣清淨機中，吸入口4係配置於殼體2的前面，因此能夠用水平回轉機構15使得吸入口4朝向人的方向同時將風向調整至人的方向。藉此，容易形成以人為中心的氣流，亦即從吹出口5吹並通過人的頭上、沿著壁面通過背面、擦過腳邊而向吸入口4吸入的氣流，所以能夠有效率地吸引人周圍的塵埃。 Further, in the air cleaner of the present embodiment, since the suction port 4 is disposed in front of the casing 2, the horizontal swing mechanism 15 can adjust the wind direction to the direction of the person while the suction port 4 faces the person. Thereby, it is easy to form a human-centered airflow, that is, an airflow that is blown from the air outlet 5 and passes through the head of the person, passes through the back surface, and passes over the foot surface and is sucked into the suction port 4, so that it can efficiently attract people around. Dust.
另外，在本實施形態的空氣清淨機中，吸入口4係配置於殼體2的前面，但也有吸入口4被配置於殼體2的前面的樣態。因此，在此種樣態中，能夠將整流機構13的動作與水平回轉機構15的動作組合以執行風向控制。詳言之，控制為藉由 水平回轉機構15使吸入口4朝向人所在的方向，再由整流機構13使風向在左右方向朝向人所在的方向。藉此，即使吸入口4不是配置在殼體2的前面，也能夠有效產生以人為中心的氣流。 Further, in the air cleaner of the present embodiment, the suction port 4 is disposed on the front surface of the casing 2, but the suction port 4 is disposed on the front surface of the casing 2. Therefore, in such a state, the operation of the rectifying mechanism 13 can be combined with the operation of the horizontal turning mechanism 15 to perform the wind direction control. In detail, control is by The horizontal turning mechanism 15 faces the suction port 4 in the direction in which the person is located, and the rectifying mechanism 13 causes the wind direction to face the direction in which the person is located in the left-right direction. Thereby, even if the suction port 4 is not disposed in front of the casing 2, the human-centered airflow can be efficiently generated.
另外，在本實施形態的空氣清淨機中，係構成為能夠由髒污檢出裝置20檢出吸入空氣的髒污程度。若在室之人的周圍浄化了，但另有髒污的發生源，則無法認為已經將室內清浄化。另外，當人在移動時，若不先將移動目的地浄化就無法保持其舒適性。髒污檢出裝置20和人檢出裝置21之連動為解決此課題的方法，藉由此動作能夠在人的移動目的地也保持舒適。亦即，必須先檢知人並將人的周圍浄化，當人的周圍之清浄度改善到優於既定狀態時，則進行控制使其也朝向沒有人的方向，對應於髒污檢出裝置20的值將人以外的空間整個予以浄化。 Further, in the air cleaner of the present embodiment, the dirt detection device 20 is configured to detect the degree of contamination of the intake air. If it is cleaned around the person in the room, but there is another source of contamination, it cannot be considered that the room has been cleaned. In addition, when a person is moving, the comfort cannot be maintained without first purifying the moving destination. The interlocking of the soil detecting device 20 and the person detecting device 21 is a method for solving this problem, and by this operation, it is possible to maintain comfort in the moving destination of a person. That is, it is necessary to first detect the person and purify the person's surroundings, and when the cleanness of the person's surroundings is improved to be better than the predetermined state, control is performed so as to also face the direction of no one, corresponding to the soil detecting device 20. The value purifies the entire space other than the person.
不過，例如當人坐在椅子等時，用人檢出裝置21會無法檢知到腳邊。另外，例如身體被家具遮蔽時，用人檢出裝置21會誤判為沒有人。當出現像這樣的人檢出裝置21的誤檢出時，可能會無法進行所欲的風向控制，而沒辦法有效率地進行空氣清浄動作。因此，在本實施形態1的空氣清淨機中，也可以構成為具備輸入關於家的隔間或障礙物的室內資訊的裝置。詳言之，具備事先輸入了例如室內的家具、窗戶或門的位置、或房間大小等的室內資訊的室內資訊取得裝置，並使用此已輸入的資訊在風向控制中修正風向。 However, for example, when a person sits in a chair or the like, the person detecting device 21 cannot detect the foot. Further, for example, when the body is covered by the furniture, the person detecting device 21 may be mistakenly judged as no one. When a erroneous detection of the person detecting device 21 as described above occurs, the desired wind direction control may not be performed, and the air cleaning operation may not be performed efficiently. Therefore, in the air cleaner of the first embodiment, it is also possible to provide a device that inputs indoor information about a compartment or an obstacle of a home. Specifically, an indoor information acquisition device that inputs indoor information such as the position of furniture, a window or a door, or a room size in advance, and corrects the wind direction in the wind direction control using the input information.
另外，上述室內資訊取得裝置並不限於直接輸入資料的形態，也可以為例如將超音波檢測器等組合到人檢出裝 置21，以檢測出隔間資訊的構成。另外，也可以為，藉由公知的通信手段，與智慧手機或個人電腦等的外部機器連動，透過通信由這些外部機器取得隔間資訊。另外，通信手段中也包含接收來自其他製品的檢測資訊或動作資訊、位置資訊為佳。藉此，能夠取得例如由空調機器的高位置得到的人資訊，進行找出被家具遮蔽的人的動作。另外，可以取得冰箱、吸塵器、微波爐、或電視機等的動作資訊或位置資訊，事先掌握人以外的熱源，以防止誤檢知。 Further, the indoor information acquisition device is not limited to a form in which data is directly input, and may be, for example, a combination of an ultrasonic detector and a human detection device. Set to 21 to detect the composition of the compartment information. In addition, it is also possible to obtain the compartment information by these external devices by communication with an external device such as a smartphone or a personal computer by a known communication means. In addition, the communication means also includes receiving detection information, action information, and location information from other products. Thereby, it is possible to obtain, for example, the person information obtained from the high position of the air conditioner, and to find out the motion of the person covered by the furniture. In addition, it is possible to obtain motion information or position information of a refrigerator, a vacuum cleaner, a microwave oven, or a television, and to grasp a heat source other than a person in advance to prevent false detection.
