<About configuration>
(Outline configuration)
First, a schematic configuration example of an air purification system (hereinafter, abbreviated as “system”) according to an embodiment of the present invention will be described.

  FIG. 1 is a schematic configuration diagram showing a schematic configuration of a system 1 according to the present embodiment. FIG. 2 is a schematic cross-sectional view showing the internal structure of the air cleaning device 2 according to the present embodiment. With reference to FIG. 1 and FIG. 2, the system 1 includes an air cleaning device 2 installed on a ceiling 11 of a room 10 and a room sensor 8 disposed away from the air cleaning device 2. The air cleaning device 2 is provided near one wall 12 of the room 10 so as to avoid the luminaire 15 located in the approximate center of the ceiling surface. The air cleaning device 2 includes a main body (housing) 20, a main body sensor 25, and a control device 5.

  As shown in FIG. 2, the main body 20 incorporates an air purifying filter 22 and a fan 23, and a suction port 21 and a blowing port 23 a are provided therebelow. The air in the room 10 sucked into the main body 20 from the suction port 21 passes through the air cleaning filter 22, and the cleaned air is blown out from the blowing port 23 a by the fan 23. In the present embodiment, the cleaned air blown out from the blowout port 23 a is blown into the room 10 through the blower mechanism 3. The blower mechanism 3 is configured such that the cleaned air is blown along the ceiling surface. A specific structural example of the blower mechanism 3 will be described later.

  Most of the pollutants generated by the human body and daily activities, such as suspended particulates, odors, and carbon dioxide, are carried upward by the heat generated by the human body. In the present embodiment, since the suction port 21 is provided in the ceiling 11 in this way, contaminants can be efficiently cleaned. In addition, the air purification apparatus 2 should just have the main-body part 20 provided in the ceiling 11 at least.

  The main body sensor 25 is provided, for example, in the main body portion 20 and detects the degree of contamination in the room 10. In this case, the main body sensor 25 is provided at a position where the contamination level of the air before being purified can be detected. Note that the main body sensor 25 may be provided on the ceiling 11, the wall 12, or the like outside the main body portion 20 as long as it is close to the main body portion 20.

  The control device 5 performs basic control of the fan 23 and performs control for adjusting the air volume from the blower mechanism 3. The control device 5 is provided in the main body 20, for example. The functional configuration of the control device 5 will be described later.

  The room sensor 8 is disposed at a position far from the air cleaning device 2 (the main body portion 20), and detects the degree of contamination in the room 10. The room sensor 8 is provided, for example, on the wall 13 farthest from the air cleaning device 2 among the walls surrounding the room 10. Note that the room sensor 8 may be disposed at other locations such as the ceiling 11 and the floor 14 as long as the room sensor 8 is located far from the main body of the air cleaning device 2 in the room 10. In FIG. 1, the direction in which the room sensor 8 is disposed as viewed from the air cleaning device 2 (main body portion 20) (hereinafter referred to as “room sensor direction”) is indicated by an arrow A1.

  In the present embodiment, both the room sensor 8 and the main body sensor 25 are dust sensors that detect dust, for example.

(Blower mechanism)
Here, a structural example of the blower mechanism 3 will be described. FIG. 3 is a cross-sectional view of the blower mechanism 3 taken along line III-III in FIG. With reference to FIGS. 2 and 3, the air blowing mechanism 3 includes a bottom wall 30 disposed below the outlet 23 a of the fan 23, and a partitioning column disposed between the lower surface of the main body 20 and the bottom wall 30. 301-304. The bottom wall 30 extends in the horizontal direction and has, for example, a rectangular shape in plan view. Further, the bottom wall 30 has an area sufficiently larger than the opening area of the outlet 23 a of the fan 23. The partition pillars 301 to 304 are disposed in the vicinity of the four corners of the bottom wall 30. Thereby, the four ventilation ports 31-34 are formed between the adjacent partition pillars, respectively.

  Thus, since the blower ports 31-34 are formed on the bottom wall 30 extended in a horizontal direction, as FIG. 1 shows, the air after the cleaning which blows off from the fan 23 is made into a ceiling surface. Can be sent along. Since the ceiling 11 of the room 10 has no obstacles such as furniture other than the lighting fixture 15, the cleaned air is carried to the wall surface. Therefore, the cleaned air can be supplied over a wide range to every corner of the room 10. Further, since the air is not directly blown to the human body, the resident can spend comfortably in the room 10. Moreover, in this Embodiment, since the four ventilation ports 31-34 are formed, the air after a cleansing can be ventilated in various directions in the room 10 without bias.

  In the present embodiment, one air outlet 31 among the four air outlets 31 to 34 faces the room sensor 8 side. The other air outlets 32, 33, and 34 are directed in a direction different from that of the room sensor 8, and the air outlet 33 is directed in a direction opposite to the room sensor direction. Further, the air blowing port 31 has a plurality of louvers 310. Similarly, the other air outlets 32, 33, and 34 have a plurality of louvers 320, 330, and 340, respectively.

  In FIG. 3, the louvers 310, 320, 330, and 340 are arranged so that their opening degrees are fully opened, for example. In this case, the air volume from each of the air outlets 31 to 34 is substantially the same. In the present embodiment, such a state is referred to as a “normal state”. The relative air volume from each of the air outlets 31 to 34 is adjusted under a predetermined condition. That is, the air purifier 2 is provided with an air volume adjusting means for adjusting the relative air volume from the air outlets 31 to 34.

(About air volume adjustment means)
In the present embodiment, the air volume adjusting means adjusts the relative air volume from the air outlets 31 to 34 by changing the direction of the louvers 320, 330, and 340. That is, while the opening degree of the louver 310 of the blower port 31 is fixed, the opening degree of the other louvers 320, 330, and 340 can be changed. The directions of the movable louvers 320, 330, and 340 are changed by position adjusting means such as the actuator 4.

  The operation of the actuator 4 and the opening adjustment of the movable louvers 320, 330, and 340 will be described with further reference to FIGS. 4A and 4B are diagrams illustrating the operation of the actuator 4. FIG. 5 is a diagram showing the direction of the louvers 310, 320, 330, and 340 when the air volume is adjusted. FIG. 5 is a cross-sectional view corresponding to FIG.

  As shown in FIGS. 3 and 5, upstream ends of the plurality of louvers 320 at the air outlet 32 are connected to a moving member 321 that is movable in the longitudinal direction. The positions of the downstream end portions of the plurality of louvers 320 are fixed. Similarly, in the air blowing ports 33 and 34, upstream end portions of the plurality of louvers 330 and 340 are connected to moving members 331 and 341 that are movable in the longitudinal direction, respectively. Further, the positions of the downstream end portions of the plurality of louvers 330 and 340 are fixed.

  With reference to FIG. 3 and FIG. 4 (A), the actuator 4 is disposed on the bottom wall 30. The actuator 4 includes an advancing / retreating portion 41 that can move in the room sensor direction and in the opposite direction. The advancing / retreating portion 41 and the moving members 321, 331, 341 are connected by rod-like connecting members 42, 43, 44, respectively. The actuator 4 changes (adjusts) the positions of the three connecting members 42, 43 and 44. The connecting members 42 and 44 are fixed to the advance / retreat portion 41 of the actuator 4, whereas the connection member 43 is rotatably attached to the advance / retreat portion 41. That is, the connecting member 43 located on the opposite side of the room sensor direction is attached to the distal end portion of the advance / retreat portion 41 by the rotation shaft 45 so as to be rotatable. In FIG. 4, the illustration of the connecting members 42 and 44 fixed to the advance / retreat portion 41 is omitted for easy understanding.

  As shown in FIGS. 4B and 5, when the actuator 4 is operated and the advance / retreat portion 41 is pushed out, the moving members 321, 331, 341 are moved along the longitudinal direction as the advance / retreat portion 41 moves. Move. Thereby, the direction (opening degree) of the movable louvers 320, 330, and 340 is changed at a time. Then, since the air volume from the air outlets 32, 33, and 34 having these louvers 320, 330, and 340 is reduced, the air volume from the air outlet 31 (louver 310) that blows air toward the wall sensor is relatively increased. To increase.

  Thus, by mounting the actuator 4 and the three connecting members 42, 43, 44 as the air volume adjusting means in the air cleaning device 2, the air volume from the air blowing port 31 can be easily increased. In the present embodiment, the movable louvers 320, 330, and 340 themselves may be regarded as being included in the air volume adjusting means.

  Further, as shown in FIG. 5, the moving members 321 and 341 located on both sides of the actuator 4 move in the direction opposite to the room sensor direction. Therefore, the direction of the louvers 320 and 340 is changed so that the air direction from the air blowing ports 32 and 34 adjacent to the air blowing port 31 approaches the room sensor direction. Therefore, since the wind whose air volume has been reduced is also directed toward the room sensor, it is possible to quickly reduce pollutants in the distance.

(Regarding the functional configuration of the control device)
FIG. 6 is a block diagram showing a functional configuration of the system 1 according to the embodiment of the present invention. Referring to FIG. 6, the control device 5 is included in the air cleaning device 2 of the system 1. The control device 5 includes a control unit 51 that performs various calculations and processes, a reception unit 52 that receives detection signals from the room sensor 8, a storage unit 53 that stores various data and programs, and a time measurement unit 54 that performs timekeeping operations. Including.

  The control unit 51 performs basic processing of the air cleaning device 2 by performing drive control of the fan 23. Further, the control unit 51 performs an air volume adjustment process for adjusting the air volume from the blower mechanism 3. Specifically, based on the detection signal from the receiving unit 52, the control unit 51 detects the degree of contamination in the vicinity of the room sensor 8, i.e., a place far from the main body unit 20 (hereinafter also referred to as “distance contamination degree”). Further, based on the detection signal from the main body sensor 25, the degree of contamination in the vicinity of the main body portion 20 (hereinafter also referred to as “neighboring degree of contamination”) is detected. It is assumed that the detection signals from the sensors 8 and 25 are input to the control unit 51 after being converted into digital signals. The control unit 51 drives and controls the actuator 4 based on the detected far and near pollution levels. The control unit 51 is realized by an arithmetic processing device such as a CPU (Central Processing Unit).

  The storage unit 53 stores in advance an air volume adjustment program for realizing an air volume adjustment process described later. Storage unit 53 is realized by a nonvolatile storage device such as a flash memory, for example. The timer 54 is a timer that measures time in accordance with an instruction from the controller 51. Note that the timer 54 may be a clock that always measures the date and time.

  In the present embodiment, the control unit 51 performs both the drive control of the fan 23 and the air volume adjustment process. However, a control unit that controls the drive of the fan 23 may be provided separately. Further, when the main body sensor 25 is provided outside the main body portion 20, a receiving portion (not shown) that receives a detection signal from the main body sensor 25 may be further provided.

<About air volume adjustment processing>
Next, the air volume adjustment process performed in the control part 51 of the control apparatus 5 is demonstrated.

  FIG. 7 is a flowchart showing the air volume adjustment processing in the embodiment of the present invention. This process is realized by the control unit 51 reading and executing the air volume adjustment program stored in the storage unit 53. The air volume adjustment process is started, for example, when the power of the air cleaning device 2 is turned on. At the start of this process, it is assumed that the louvers 310, 320, 330, and 340 in the air outlets 31 to 34 of the air blowing mechanism 3 are set to the normal state as shown in FIG.

  Referring to FIG. 7, first, control unit 51 detects distant pollution level “Cf” from room sensor 8 via receiving unit 52 (step S <b> 1). Further, the vicinity contamination degree “Cn” is detected from the main body sensor 25 (step S2).

  The control unit 51 determines whether or not the near pollution degree Cn is greater than or equal to the far pollution degree Cf (step S3). Otherwise, that is, when the far pollution degree Cf is higher than the near pollution degree Cn (NO in step S3), the control unit 51 adjusts the opening degree of the louvers 320, 330, and 340 (step S4). ). Specifically, the control unit 51 operates the actuator 4 to push out the advance / retreat unit 41. Thereby, the direction of the louvers 320, 330, and 340 in a direction different from the wall sensor direction is changed, and as a result, only the amount of air blown from the air outlet 31 on the wall sensor side is relatively increased.

  When the opening degree is adjusted, the control unit 51 turns on the adjustment flag and instructs the time measurement unit 54 to start time measurement (step S5). Thereafter, the process returns to step S1.

  On the other hand, when it is determined that the near pollution degree Cn is equal to or greater than the far pollution degree Cf (YES in step S3), it is determined whether or not the adjustment flag is ON. If the adjustment flag is not ON (NO in step S6), the process returns to step S1. That is, in this case, since the opening degree of all the louvers 310, 320, 330, 340 is constant (fully open) and remains in the normal state, the contamination degree detection process is continued, and the air volume from each of the air outlets 31-34. Are maintained evenly.

  If the adjustment flag is ON (YES in step S6), it is determined whether, for example, 5 minutes have elapsed since the adjustment flag was turned on (step S7). That is, it is determined whether or not the time measuring unit 54 has timed for 5 minutes or more. If 5 minutes have not elapsed (NO in step S7), the process returns to step S1, but if 5 minutes have elapsed (YES in step S7), the opening degree of louvers 320, 330, 340 is in a normal state (fully open). (Step S8). Specifically, the actuator 4 is actuated again to move the advance / retreat unit 41 to the original position. Thereby, the air flow rate from all the air outlets 31-34 is changed to the same amount again.

  When the opening degree of the louvers 320, 330, and 340 is returned to the normal state, the control unit 51 turns off the adjustment flag and instructs the timing unit 54 to stop timing (step S9). Thereafter, the process returns to step S1. The series of processes described above is continued until, for example, the power of the air cleaning device 2 is turned off.

  When the contamination level in the room 10 is detected only by the main body sensor 25 provided in the air cleaning device 2, dust collection is delayed because the detection of the contamination is delayed when the contamination source is far from the air cleaning device 2. Efficiency is reduced. This is particularly noticeable when the room 10 is a large space. On the other hand, in the present embodiment, since the room sensor 8 is disposed at a position far from the air cleaning device 2, the position of the contamination source cannot be specified, but the contamination at a position far from the air cleaning device 2. It can be determined whether there is a source. Further, when the air on the room sensor 8 side is more polluted than the main body sensor 25 side, the air volume adjustment is performed so as to send more air to the room sensor 8 side. Therefore, according to this Embodiment, even if the room 10 is large space, since it can ventilate intensively to the pollution generation source side, the dust collection efficiency of the air purification apparatus 2 can be improved.

  Further, the control unit 51 can relatively increase the amount of air blown from the air blowing port 31 facing the room sensor direction only by performing simple drive control of the actuator 4. Therefore, the processing load of the control unit 51 can be suppressed.

  In the present embodiment, the opening degree of each louver is maximized in the normal state. However, if the air volume from each of the air outlets 31 to 34 is equal, the opening degree of each louver is maximized in the normal state. Not necessarily. In that case, when the degree of contamination on the room sensor 8 side is higher than the degree of contamination on the main body sensor 25 side, the opening degree is set so as to maximize only the opening degree of the louver 310 in the air outlet 31 in the room sensor direction. You may adjust. That is, the air volume adjusting means may be configured to change only the opening degree (direction) of the louver 310.

  The room sensor 8 and the main body sensor 25 are dust sensors that detect dust, but may be odor sensors that detect odor. Alternatively, the room sensor 8 and the main body sensor 25 may each include a plurality of sensors that detect a plurality of types of contaminants. In this case, for example, the dust contamination degree is higher on the room sensor 8 side, and the odor contamination degree is higher on the main body sensor 25 side. In such a case, for example, the control unit 51 may control the air volume by giving priority to the degree of dust contamination over the degree of odor contamination, or the statistical value (for example, an average value or the degree of odor contamination and the degree of dust contamination). Or the maximum value) may be used to control the air volume.

  In the present embodiment, the cleaned air is blown in four directions from the blower mechanism 3, but the blower mechanism 3 includes at least one blower opening facing the room sensor direction and the wall sensor direction. What is necessary is just to have one ventilation port which faces a different direction.

  Further, the structure of the blower mechanism 3 is not limited to the example shown in FIGS. Another structural example of the blower mechanism 3 will be described below.

<Other structural examples of the blower mechanism>
FIG. 8 is a diagram showing another structural example of the air blowing mechanism in the embodiment of the present invention. With reference to FIG. 8, the blower mechanism 3 </ b> A is formed by one frame member 6 and a plurality of blower port forming members 7. In FIG. 8, only one air blowing port forming member 7 is shown.

  The frame member 6 is divided into four by a partition member 62 and forms four openings 63 to 66 penetrating vertically. The outer frame 61 of the frame member 6 is formed in a rectangular shape, for example. The upper end of the outer frame 61 is attached to the lower surface of the main body 20 of the air cleaning device 2. The partition member 62 is lower than the height of the outer frame 61. The partition member 62 has a cross shape, and is fixed in the outer frame 61 so that the four openings 63 to 66 have the same shape. It is desirable that the air outlet 23 a of the fan 23 is disposed above the center portion of the partition member 62. In addition, all the four opening parts 63-66 may not be the same shape, for example, the opening part of the same shape may be formed 2 each.

  The blower port forming member 7 is unitized and is detachably fitted into the openings 63 to 66 of the frame member 6. The blower port forming member 7 includes an engagement frame 71 that is engaged with an inner frame surrounding each of the openings 63 to 66, and a plate-like wind direction guide 72 that is connected to the engagement frame 71. The engagement frame 71 is also rectangular, and the wind direction guide 72 extends obliquely downward from the lower end portion of one side of the engagement frame 71. Thereby, the air blown out from the blowout port 23 a is blown in one direction along the wind direction guide 72 from the blower port 73 formed in each blower port forming member 7.

  Further, the wind direction guide 72 is bent so that at least the tip portion is substantially parallel to the ceiling surface. Therefore, even when such a blower mechanism 3A is mounted on the air cleaning device 2, the cleaned air can be blown along the ceiling surface.

  In this example, since the blower port forming member 7 can be detachably fitted into any of the four openings 63 to 66 in the frame member 6, the resident can freely select the blowing direction. it can. That is, for example, when the wind direction from the blower mechanism 3A is confirmed at the time of the trial operation and the desired wind direction is not obtained, the wind direction can be changed by changing the mounting direction of the blower port forming member 7. Therefore, the resident can freely set and change the blowing direction according to the furniture layout in the room 10 or the like.

  9 and 10 are diagrams showing examples of combinations of wind directions blown from the blower mechanism 3A. Referring to FIG. 9, in the first example, the wind direction from the blower mechanism 3 </ b> A is four directions. Referring to FIG. 10, in the second example, the direction of wind from air blowing mechanism 3 </ b> A is three directions. However, in both FIG. 9 and FIG. 10, at least one of the two openings 63 and 64 positioned in the room sensor direction (for example, the opening 63) is such that the air blowing port 73 faces the room sensor direction. A blower port forming member 7 is installed.

  When adjusting the air volume with the configuration of the air blowing mechanism 3A, at least the air volume from the air blowing port 73 facing the room sensor direction, that is, the air volume from the opening 63 may be increased. FIG. 11 is a diagram conceptually illustrating a state in which the air volume adjustment is performed in the air blowing mechanism 3 </ b> A illustrated in FIG. 10.

  As shown in FIG. 11, in the second example, the control unit 51 controls the air volume from, for example, the air outlet 73 located in the opening 63 and the opening 64 so as to increase more than others. In this case, for example, a blocking unit (not shown) capable of blocking the other two air outlets 73 and a position adjusting unit (for example, the actuator 4) capable of adjusting the position of the blocking unit are mounted as the air volume adjusting unit. It may be. Thereby, also in this example, since the air volume is increased only in the direction closer to the room sensor 8, the dust collection efficiency can be increased.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
