It can be cleaned without stirring.

JP 2000-199634 A

  In general, air cleaners that are sold perform suction and blowout with only one piece of equipment, so the contaminated air that is close to both the suction and blowout openings spreads throughout the room by the air coming out of the blowout openings and is cleaned. There is a problem that the effect becomes low.

  In addition, the system of Patent Document 1 is excellent in that it does not stir contaminated air, but a hole is made in the wall or ceiling, and a duct is installed in the wall. There is a problem that it takes. Further, since the outlet and the suction port are fixed, a stagnation airflow exists in the room, and it is difficult to clean the air around the stagnation airflow.

  Accordingly, an object of the present invention is to provide an air cleaning system that can reduce the burden during introduction and replacement, can be more efficient, and can further improve the air cleaning capability in order to solve the above-described conventional problems. And

Embodiments of the present invention will be described below. In the following description, the same components are denoted by the same reference numerals, and description thereof is omitted as appropriate.
(Embodiment 1)
First, the outline | summary is demonstrated about the air purifying system of Embodiment 1 of this invention.

  The air purification system according to the first embodiment includes a plurality of air purification devices for purifying air in a closed space, and the plurality of air purification devices switch between air suction and blowing on the side surface and the upper surface, respectively. An opening that is capable of switching air suction and blowing from the opening in cooperation with each other in accordance with an air-contaminated place in the closed space, and the air volume, wind direction, and wind speed from the opening. It is characterized in that the operation is performed so as to change.

  When introducing this system, only a plurality of air purifiers are placed, so installation work is unnecessary and there is no burden of introduction. In addition, by arranging a plurality of air cleaning devices and operating in cooperation with each other, various airflows can be generated. Note that the cooperative operation refers to, for example, changing the air volume, the wind direction, and the like while communicating such information among a plurality of air cleaning devices.

  In particular, each air cleaning device can switch between suction and blowout of air from the opening, so the suction location and the blowout location are not constant, and the entire room does not have to be constantly stagnated in the closed space. The air can be purified.

In the above air cleaning system, the plurality of air cleaning devices are installed such that one of the side surfaces is in contact with a wall in the closed space and faces each other.
When the air flow is controlled by one air cleaning device, the most difficult place to control is the air in the space located on the opposite side of the air cleaning device in the closed space. By installing the air purifiers so as to face each other, it becomes easy to control the air at the most difficult positions of each other, and the maximum effect can be obtained with the minimum configuration.

  In the above air cleaning system, a detector capable of detecting contaminated air and / or people is provided, and an optimal air flow is created according to the location of the air contamination based on the information on the contaminated air and / or people. It is characterized by that.

For example, in a hospital room, a person may become a source of odor due to illness or a source of viruses.
Therefore, it is possible to construct an air cleaning system with higher cleaning efficiency by detecting the space of contaminated air and the position of a person and generating an air flow that cleans mainly the contaminated air in the space.

Further, in the above air cleaning system, each air cleaning device operates by using three surfaces that come into contact with contaminated air or a person as a suction port and the other surface as a discharge port.
For example, two air purifiers are installed in a rectangular parallelepiped closed space so as to face each other so that one wall of the side surface of the air purifier is in contact with the center of the long side wall. Here, for the following description, a surface parallel to the wall is referred to as an opposing surface, a surface perpendicular to the wall and perpendicular to the ground is referred to as a side surface, and a surface parallel to the ground and not to the ground is referred to as an upper surface.

  When contaminated air is filled in a space where the longitudinal direction of the room is halved, each air purifier sucks the side, the opposite surface and the upper surface of the contaminated air, and blows out the side opposite to the contaminated air To make it work. At this time, since there is no contaminated air in the vicinity of the outlet, the agitation of the contaminated air does not occur.

Therefore, when the half area in the longitudinal direction of the room is contaminated air, it is possible to clean the contaminated air without stirring by operating as described above.
Further, in the above air purification system, the air purifier closest to the contaminated air or person sucks three surfaces contacting the contaminated air or person and blows out the other surface, and the opposing air purifier is the contaminated air or It is characterized in that the three surfaces close to a person are blown out and the other surface is inhaled to perform a cooperative operation.

  For example, consider a case where two air purifiers are installed in the closed space of a rectangular parallelepiped in the same manner as described above and contaminated air is present in a quarter of the room. At this time, the air purifier closest to the contaminated air sucks the side surface, the opposite surface and the upper surface close to the contaminated air, and blows the side surface on the opposite side to the contaminated air, as before. Moreover, the air purifier in the position opposite to the nearest air purifier operates by using the side surface opposite to the contaminated air as suction, and the side surface, upper surface, and opposing surface on the other contaminated air side as blowing.

  By the above operation, there is no other airflow near the blowout of the air purifier near the contaminated air, and the air purifier on the side far from the polluted air sends the polluted air to the air purifier on the contaminated air side. Therefore, the contaminated air can be cleaned without stirring.

  Also, in the above air cleaning system, the air cleaning device close to the contaminated air or person blows out the opposing surface and sucks other than the opposing surface, and the air cleaning device in the opposite side sucks the opposing surface and blows out the other surface It is characterized by operation.

  As described above, a case where two air cleaning devices are installed in a closed space of a rectangular parallelepiped will be described. Consider the case where the half space in the short side direction of the room is contaminated air. The air cleaning device needs at least one suction surface and one discharge surface. Therefore, when there is an air cleaning device in the contaminated air, since at least one is blown out, the contaminated air may be agitated by the blown airflow.

  Therefore, by setting the facing surface of the air purifier on the non-contaminated side as the outlet, and by sucking the facing surface of the facing air purifier, the contaminated air carried by the blown airflow is facing the air purifier. Since it is cleaned immediately by the apparatus, it is possible to clean contaminated air without stirring. Further, since the contaminated air is collected in the air purifier in the contaminated air by the air flow blown out from the air purifier on the uncontaminated side, the cleaning effect is further enhanced.

Further, in the above air cleaning system, the opposed surface and the upper surface are sucked, and suction and blowing are set so that a swirl flow is generated on the other surface, and each is operated.
Consider the case where contaminated air is in the middle of a closed space with the same closed space and two air purifiers. As before, one of the faces must be blown out, but since the contaminated air is in the center of the room, any face can be agitated by the blown air flow, regardless of the face.

  Therefore, by operating as described above, the contaminated air near the center of the room is sucked by the facing surface and the top surface, and the contaminated air carried by the side airflow is sucked by the suction port of the facing air purifier. Can clean contaminated air without stirring.

Next, the air cleaning system of the first embodiment will be specifically described with reference to the drawings.
FIG. 1 is a schematic perspective view showing the overall configuration of the air cleaning system according to the first embodiment, FIG. 2 is a schematic perspective view showing the configuration of an air cleaning device for cleaning air, and FIG. 4 is a flow chart showing the operation of the present air cleaning system, FIGS. 5, 7, 9, and 11 are diagrams showing the operational relationship of each opening surface of the air cleaning device, and FIGS. 6, 8, 10, and 12 are closed. It is the schematic which shows the flow (airflow) of the air in space.

  The air purification system according to the first embodiment is a system that purifies air in a closed space using a plurality of air purifying devices that purify air. First, an outline of the entire air cleaning system will be described with reference to FIG. 1, and then an example of an air cleaning device with reference to FIGS. 2A and 2B, and FIGS. 3A to 3D. An example of the arrangement of the target closed space and the air purifier will be described. Thereafter, the operation flow of the air cleaning system will be described with reference to FIG. 4, and the method of controlling a plurality of air cleaning devices in cooperation with each other with reference to FIGS. To do.

  First, the outline | summary is demonstrated about the whole structure of the air purification system of this Embodiment 1 using FIG. In order to distinguish the two air purifiers in the description, the air purifier on the reference numeral 1 side is defined as the first air purifier, and the air purifier on the reference numeral 2 side is defined as the second air purifier.

  The air cleaning system according to the first embodiment of the present invention includes a plurality of (two in the figure) air cleaning devices in a room 51, and an opening (see FIG. The 1st air purifying apparatus 1 and the 2nd air purifying apparatus 2 which have not shown are arrange | positioned. Then, in order to detect contaminated air 5 and people in the room 51, for example, four detectors 4 at the four corners in the room 51 are used as infrared gas analysis detectors that specify the type of gas by the absorbed wavelength. (One is omitted in the figure), or the first air cleaning device 1 and the second air cleaning device 2 are provided with at least one of the two detectors of the detector 3. Infrared gas analysis detectors can measure not only the absorption wavelength but also the temperature distribution by infrared rays. If the temperature distribution of people is stored in advance, not only the detection of contaminated air (gas) but also the detection of people Is also possible.

  Here, in the case of the detector 3 alone, it is necessary to specify the location of contaminated air or a person by cooperation of two sensors (detectors). Therefore, for example, a method of identifying contaminated air or a person's location by communication cooperation between the sensors (detectors) of the first air cleaning device 1 and the second air cleaning device 2, or the detector 3 includes at least two sensor units. A method using a material having the above can be considered. Also, four detectors 4 (three in the figure) are used, but this is to make it easy to detect the interior of the room 51 evenly. Identification is possible.

  In the first embodiment, each of the first air cleaning device 1 and the second air cleaning device 2 includes a control unit (not shown) for controlling the respective devices, and, for example, an infrared ray between the devices. For example, information is shared by performing communication with a communication unit (not shown) through a communication control. At this time, in order to more accurately perform the linking operation of the two devices, either device is given priority, or each device is linked and controlled using a separately provided centralized control unit (not shown). It is desirable to do.

  And this air purifying system specifies the location of the contaminated air 5 and the person based on the information signal detected by the detector 4 or the detector 3, and the first air purifier according to the location of the contaminated air 5 and the person. While controlling each of the apparatus 1 and the second air purifying apparatus 2 in cooperation with each other, the contaminated air in the room 51 is purified by switching between suction and blowing from each opening and controlling the air volume, wind direction, and wind speed. System.

  Next, the 1st air cleaning apparatus 1 (FIG. 2 (a) side) and the 2nd air cleaning apparatus 2 (FIG. 2 (b) side) which clean air using FIG. 2 (a), (b) are described. . The 1st air purification apparatus 1 and the 2nd air purification apparatus 2 have the opening part which can switch the suction | inhalation part and blowing part in three surfaces of a side surface, and an upper surface according to the location of contaminated air. In the first air cleaning device 1 shown in FIG. 2 (a), the surface parallel to the horizontal plane and not in contact with the floor is defined as the upper surface 11, and the surface parallel to the wall 51a and not in contact with the wall 51a is defined as the facing surface 12 and the facing surface 12. The left side surface toward the side surface 13 is referred to as a side surface 13, and the right side surface toward the facing surface 12 is referred to as a side surface 14. Similarly, in the second air cleaning device 2 shown in FIG. 2 (b), the surface parallel to the horizontal plane and not in contact with the floor is the upper surface 21, and the surface parallel to the wall 51d and not in contact with the wall 51d is the opposing surface 22. A left side surface facing the facing surface 22 is a side surface 23, and a right side surface facing the facing surface 22 is a side surface 24.

  Further, inside the first air cleaning device 1 and the second air cleaning device 2, a cleaning unit (not shown) for cleaning contaminated air is provided. Examples of the cleaning unit that cleans air include a deodorizing device, a sterilizing device, and a filter.

  3 (a) to 3 (d) are examples of a room to be air cleaned, FIG. 3 (a) is a plan view, FIG. 3 (b) is a left side view, and FIG. 3 (c) is a front view. FIG. 3D shows a right side view. Here, in order to distinguish the two air purification devices in the explanatory text, the lower (wall 51d side) air purification device is defined as the first air purification device 1 in the plan view of FIG. The air purifier on the wall 51a side) is defined as the second air purifier 2. Further, the room 51 is provided with detectors 4 for detecting contaminated air 5 and people (in FIG. 3, three places at the corners of the ceiling). Hereinafter, information on the contaminated air detected by the detector 4 is provided. Based on this, we will describe the cooperative operation of each air purifier. In the following description, the case where contaminated air or the like is detected by the detector 4 is described. However, as described above, if an appropriate detection range is set using the detector 3 instead of this, Almost the same effect can be obtained. Here, the space of the room 51 is divided as shown by the solid line in FIG. 3A and defined as a space 52, a space 53, a space 54, a space 55, and a space 56, respectively.

  In the case of this room 51, it is desirable to arrange | position the 1st air purifying apparatus 1 and the 2nd air purifying apparatus 2 like Fig.3 (a)-(d). For example, when the air flow in the closed space is controlled by one air purifier, it is difficult to control the air in the space opposite to the air purifier, so the first air purifier 1 and the second air purifier By arranging the two air purifiers so as to face each other (face to face) as in 2, the maximum effect can be obtained with a smaller number of air purifiers.

Then, the operation | movement flow of an air purifying system is demonstrated using FIG.
The air cleaning system according to the first embodiment is configured so that the first air cleaning device 1 and the second air are based on an information signal corresponding to a location detected by the detector 4 (contaminated air 5 or a location of a human contaminated space). This is a system that efficiently cleans the air in the room 51 by switching and operating the suction and blowing of each opening of the cleaning device 2.

  First, when the contaminated air 5 or a person is detected by the detector 4 using infrared rays (step S1), the location of the contaminated air 5 or the contaminated space by the person is specified (step S2). Here, for example, a patient may have a virus or the like in a hospital room. In that case, it is considered that there is a virus or the like in the air around the patient, and the position of the person is treated as a space that needs to be cleaned. Therefore, when a person is detected by the detector 4 in a hospital room, the position where the person is present needs to be cleaned (in the following description, the word “contaminated space place” is used to correspond to the above-described contents). ).

  Depending on which of the spaces shown in FIGS. 3 (a) to 3 (d) the location of the contaminated space is present, the suction and blowout of each opening is set and operated corresponding to each space. Here, for example, when the contaminated air 5 is present in the space 54, it is point symmetric with respect to the case where the contaminated air is present in the space 53. What is necessary is just to set and operate in point symmetry with the case.

  Here, when the location of the contaminated space is the space 52 and the space 53 (step S3), the suction and blowing operations of the openings of the first air cleaning device 1 and the second air cleaning device 2 are shown in FIGS. (Step S4), and operate each of the first air cleaning device 1 and the second air cleaning device 2 (Step S11).

The first operation (the operations in steps S3 and S4) when the contaminated air 5 fills the space 52 and the space 53 will be described with reference to FIGS. 5, 6A, and 6B.
FIG. 5 shows an operation method of each of the air purifying apparatuses 1 and 2, and FIGS. 6A and 6B show schematic views of a contaminated space location by the contaminated air 5 and a first air flow at that time.

  As shown in FIGS. 6A and 6B, when the entire left half of the room 51 (the spaces 52 and 53 in FIG. 3A) is a contaminated space location due to the contaminated air 5, the contaminated air 5 is the first air cleaner. Since the device 1 and the second air cleaning device 2 are in contact with each other, it is best to operate the portion of the first air cleaning device 1 and the second air cleaning device 2 that contacts the contaminated air 5 by suction. That is, it is desirable to set and operate each as shown in FIG. At this time, air currents 101 and 102 are formed by the suction operation of the first air cleaning device 1 and the second air cleaning device 2 as shown in FIG. Further, the air flow 103 is formed by the blowing operation of the first air cleaning device 1 and the second air cleaning device 2, and the air current 103 is collided with the air current 104 as shown in FIG. There is an air flow. The contaminated air 5 is sucked and cleaned by the first air cleaning device 1 and the second air cleaning device 2 by the air currents 101 and 102, and the contaminated air 5 located above the room 51 by the air current 104 is the first air. It is carried to the vicinity of the cleaning device 1 and the second air cleaning device 2, and the cleaning effect is further enhanced.

  Further, when the contaminated space is the space 53 in FIG. 3A (step S5), the suction and blowing operations of the openings of the first air cleaning device 1 and the second air cleaning device 2 are shown in FIGS. Settings are made as shown in a) and (b) (step S6), and each of the first air cleaning device 1 and the second air cleaning device 2 is operated (step S11).

The second operation (the operations in steps S5 and S6) when the contaminated air 5 fills the space 53 will be described with reference to FIGS. 7 and 8A to 8C.
FIG. 7 shows an operation method of each air cleaning device, and FIGS. 8A to 8C show schematic views of a contaminated space location by the contaminated air 5 and a second air flow at that time.

  As shown in FIGS. 8A to 8C, when the quarter of the room 51 (the space 53 in FIG. 3A) is a contaminated space location by the contaminated air 5, the contaminated air 5 is the first air cleaning device 1. Therefore, it is best to operate the surface of the first air cleaning device 1 in contact with the contaminated air 5 by suction. Moreover, the 2nd air purification apparatus 2 forms airflow which directs the contaminated air 5 to the suction inlet of the 1st air purification apparatus 1, and air purification capability becomes the highest. That is, it is desirable to set and operate each as shown in FIG.

  As shown in FIGS. 8A to 8C, airflows 105 and 108 are generated by the suction of the side surface 14 of the first air cleaning device 1 and the blowout of the side surface 23 of the second air cleaning device 2, and the air currents 105 and 108 are formed near the wall 51c. The first air cleaning device 1 can suck in some contaminated air 5. Airflows 106 and 107 are formed by the suction of the upper surface 11 and the opposing surface 12 of the first air cleaning device 1 and the blowing of the upper surface 21 and the opposing surface 22 of the second air cleaning device 2, and the contaminated air 5 becomes the first air cleaning device. 1 is prevented from going close to the blow-out surface of the side surface 13. As a result, the contaminated air 5 can be efficiently cleaned by the first air cleaning device 1 without being stirred into the room 51.

  Moreover, when the location of the contaminated space is the space 53 and the space 55 (step S7), the suction and blowing operations of the openings of the first air cleaning device 1 and the second air cleaning device 2 are shown in FIGS. 9 and 10A. To (c) are set (step S8), and each of the first air cleaning device 1 and the second air cleaning device 2 is operated (step S11).

A third operation when the contaminated air 5 fills the space 53 and the space 55 will be described with reference to FIGS. 9 and 10A to 10C.
FIG. 9 shows an operation method of each air purifier, and FIGS. 10 (a) to 10 (c) show schematic views of the location of the contaminated space by the contaminated air 5 and the third airflow at that time.

  10 (a) to 10 (c), it is best to suck all the surfaces of the first air cleaning device 1 and operate all the surfaces of the second air cleaning device 2 by blowing. At least one suction surface and one blowing surface are required. Therefore, at least one blowing surface is necessary for the first air cleaning device 1, and the contaminated air 5 may be agitated by the blowing airflow.

  Therefore, the operation is performed as shown in FIG. Airflows 109, 110, and 111 are created by suction of the upper surface 11, the side surface 13, and the side surface 14 of the first air cleaning device 1 and blowing out the upper surface 21, the side surface 23, and the side surface 24 of the second air cleaning device 2. Thus, the contaminated air 5 near the wall surface of the first air cleaning device 1 is cleaned by the first air cleaning device 1.

  Further, the air flow 112 is formed by blowing out the facing surface 12 of the first air cleaning device 1 and sucking the facing surface 22 of the second air cleaning device 2, and the contaminated air 5 carried by the facing surface 12 is transferred to the facing surface 22. The contaminated air 5 can be cleaned by the second air cleaning device 2. As described above, when contaminated air exists in the space 53 and the space 55, it can be efficiently cleaned.

  When the location of the contaminated space is the space 56 (step S9), the suction and blow-out operations of the openings of the first air cleaning device 1 and the second air cleaning device 2 are shown in FIGS. ) (Step S10), and operate each of the first air cleaning device 1 and the second air cleaning device 2 (step S11).

The operation when the contaminated air 5 fills the space 56 will be described with reference to FIGS. 11 and 12A to 12C.
FIG. 11 shows the method of the fourth operation (steps S9 and S10) of each air purifier, and FIGS. 12A to 12C are schematic views of the location of the contaminated space by the contaminated air 5 and the fourth airflow at that time. Respectively.

  When the center of the room is a contaminated space with the contaminated air 5 as shown in FIGS. 12A to 12C, when any surface is blown out, as in FIGS. 10A to 10C. There is a possibility that the contaminated air 5 is stirred. Further, unlike the above-described contents, the contaminated air 5 is not biased, so half of the contaminated air 5 can be cleaned in the same operation as before, but the other half of the contaminated air 5 may be agitated. . Therefore, each is set and operated as shown in FIG.

  As shown in FIG. 13, the contaminated air 5 near the center of the room sucks the upper surface 11 and the opposing surface 12 of the first air cleaning device 1, and sucks the upper surface 21 and the opposing surface 22 of the second air cleaning device 2. As a result, airflows 112 and 113 are formed, and the contaminated air 5 near the center is cleaned.

  However, the contaminated air 5 may be agitated by the blowing operation of the side surface 13 of the first air cleaning device 1 and the side surface 23 of the second air cleaning device 2. Therefore, the side surface 14 of the first air cleaning device 1 and the side surface 24 of the second air cleaning device 2 are set to the suction operation, and the air flow 114 is generated. Thus, the contaminated air 5 riding on the air flow blown from the side surface 13 of the first air cleaning device 1 is sucked by the side surface 24 of the second air cleaning device 2 and blown from the side surface 23 of the second air cleaning device 2. The contaminated air 5 riding on the air current is sucked by the side surface 14 of the first air cleaning device 1 and can be cleaned.

  In the first embodiment, an example of contaminated air (gas) that can be cleaned by a technique that is currently in practical use has been described in detail as an air cleaning target.
