However, in the furniture disclosed in Patent Document 1, air is taken into the partition panel from the side (horizontally), and in the air purifier storage type partition disclosed in Patent Document 2, air is taken into the main panel from the side (horizontally). In either case, there is a problem in that it is difficult to sufficiently circulate air in the indoor space in the vertical direction.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a partition type air cleaner that can sufficiently circulate the air in an indoor space in the vertical direction.

In order to achieve the above object, the partition-type air purifier according to the present invention is characterized by comprising: a partition body having a support extending in a vertical direction and separating a first space and a second space adjacent to each other in a horizontal direction; a housing having an air intake port and an air exhaust port that are opened in opposite directions; a blower that is accommodated inside the housing and sucks in air through the air intake port and exhausts the air from the air exhaust port; a filter that is accommodated inside the housing and purifies the air sucked in through the air intake port; and a movable housing that can be rotated relative to the support. The housing has a mounting part for mounting an air blower to the housing, and the center line of rotation of the housing rotated by the mounting part is horizontal and extends in a direction perpendicular to the directions in which the air intake and the exhaust port are pointed , and when the directions in which the air intake and the exhaust port are pointed coincide with the vertical direction, a portion of each of the air intake and the exhaust port is disposed in the first space and another portion is disposed in the second space , and two fan filter units having the housing, the blower and the filter are provided in two tiers, one above the other.

In this configuration, the direction in which the intake port and the exhaust port are directed can be appropriately adjusted by rotating the housing on the rotation center line. When the intake port is directed vertically upward, an air flow from vertically upward toward the intake port and an air flow from the exhaust port vertically downward can be created, and when the intake port is directed vertically downward, an air flow from vertically downward toward the intake port and an air flow from the exhaust port vertically upward can be created. Therefore, in either of these cases, the air in the indoor space can be sufficiently circulated in the vertical direction. Furthermore, according to the partition-type air purifier of the present invention, when the direction in which the intake port and the exhaust port are directed coincides with the vertical direction, a part of each of the intake port and the exhaust port is disposed in the first space and the other part is disposed in the second space, so that in both the first space and the second space, the air directly above the housing can be made to flow directly below, or the air directly below the housing can be made to flow directly above. Therefore, the air in the lower part of the first space and the second space can be sufficiently circulated. In addition, even if a desk is placed next to the partition body, the air on the desk top is less likely to be disturbed, so documents on the desk top are less likely to fly up and conversations are less likely to be disturbed. In addition, with the partition-type air purifier according to the present invention, the amount of air sucked into the first space and the second space from the air intake can be finely adjusted by finely adjusting the direction in which the air intake is pointed. Since the blower and filter are housed inside the housing, there is no need to provide a complex air flow path outside the housing, and the device can be manufactured inexpensively with a simple configuration. Since the blower is protected by the housing, it is less likely to be damaged, and it is safer than when the blower is exposed.

Further, according to the partition type air cleaner according to the present invention, variations in usage can be increased by appropriately adjusting the directions in which the intake ports and exhaust ports of the two fan filter units are directed.

Another feature of the partition-type air purifier according to the present invention is that the partition body has a partition wall that separates the first space from the second space, and the partition wall extends in the same direction as the rotation center line in a plan view and is provided below the rotation center line. In this configuration, air discharged from an exhaust port facing vertically downward can be smoothly blown into the indoor space along the side surface of the partition wall. Also, when the intake port is facing vertically downward, air in the indoor space can be smoothly guided to the intake port along the side surface of the partition wall.

Another feature of the partition-type air purifier according to the present invention is that the partition wall is provided with a display device for displaying various information. In this configuration, various information can be provided by the display device.

In order to achieve the above object, the partition type air cleaner according to the present invention is characterized in that the partition main body has a pillar extending in the vertical direction and partitions a first space and a second space that are adjacent to each other in the horizontal direction; a housing having an intake port and an exhaust port that are open toward opposite sides; a blower that is housed inside the housing and takes in air from the intake port and discharges the air from the exhaust port; and the housing. a filter that is housed inside the housing and that cleans the air taken in from the intake port; and a mounting part that rotatably attaches the housing to the support column, and the housing is rotated by the mounting part. a rotational centerline of which is horizontal and extends in a direction perpendicular to each direction in which the intake port and the exhaust port are oriented; When the direction coincides with the vertical direction, a part of each of the intake port and the exhaust port is arranged in the first space, and the other part is arranged in the second space , and the partition main body has a partition wall that partitions the first space and the second space, and the partition wall extends in the same direction as the rotation center line in plan view and is provided below the rotation center line. The partition wall is provided with a display device for displaying information regarding various types of caution or information regarding advertisements .

With this configuration, by rotating the housing on the rotation center line, the direction in which the intake port and the exhaust port are directed can be adjusted as appropriate. When the intake port is directed vertically upward, it is possible to create a flow of air from vertically upward toward the intake port and a flow of air directed vertically downward from the exhaust port. In this case, it is possible to create a flow of air from vertically below toward the intake port and a flow of air from the exhaust port vertically upward. Therefore, in any of these cases, the air in the indoor space can be sufficiently circulated in the vertical direction. Further, according to the partition type air cleaner according to the present invention, when the direction in which the intake port and the exhaust port are directed coincides with the vertical direction, a portion of each of the intake port and the exhaust port is arranged in the first space. At the same time, the other part is arranged in the second space, so that in both the first space and the second space, the air directly above the housing can flow directly below, or the air directly below the housing can flow directly below. It can flow upwards. Therefore, the air in the lower portions of the first space and the second space can be sufficiently circulated. Furthermore, even when a desk is placed next to the partition main body, the air above the desk top is not easily disturbed, so documents on the top can be prevented from flying up and conversation from being disturbed. Further, according to the partition type air cleaner according to the present invention, by finely adjusting the direction in which the intake port is directed, the amount of air taken into each of the first space and the second space from the intake port can be finely adjusted. can. Since the blower and filter are housed inside the housing, there is no need to provide a complicated air flow path outside the housing, and the structure can be manufactured at low cost with a simple configuration. Since the blower is protected by the housing, it is less susceptible to damage and is safer than when the blower is exposed.

In this case, it is possible to create a flow of air from vertically below toward the intake port and a flow of air from the exhaust port vertically upward. Therefore, in any of these cases, the air in the indoor space can be sufficiently circulated in the vertical direction. Further, according to this, when the direction in which the intake port and the exhaust port are directed coincides with the vertical direction, a part of each of the intake port and the exhaust port is arranged in the first space, and the other part is arranged in the first space. Since the housing is arranged in two spaces, in both the first space and the second space, air directly above the housing can flow directly below, or air directly below the housing can flow directly upwards. Therefore, the air in the lower portions of the first space and the second space can be sufficiently circulated. Furthermore, even when a desk is placed next to the partition main body, the air above the desk top is not easily disturbed, so documents on the top can be prevented from flying up and conversation from being disturbed. Moreover, according to this, by finely adjusting the direction in which the suction port is directed, it is possible to finely adjust the amount of air taken into each of the first space and the second space from the suction port. Since the blower and filter are housed inside the housing, there is no need to provide a complicated air flow path outside the housing, and the structure can be manufactured at low cost with a simple configuration. Since the blower is protected by the housing, it is less susceptible to damage and is safer than when the blower is exposed.

Then, as shown in FIG. 1, when the intake port 42 is directed vertically upward, it is possible to create an air flow from vertically upward toward the intake port 42 and an air flow from the exhaust port 44 vertically downward. In addition, although not shown, when the intake port 42 is directed vertically downward, it is possible to create an air flow from vertically downward toward the intake port 42 and an air flow from the exhaust port 44 vertically upward. Therefore, in either of these cases, the air in the indoor space S can be sufficiently circulated in the vertical direction.

As shown in FIG. 3, when the direction in which the intake port 42 and the exhaust port 44 are oriented coincides with the vertical direction, a portion of each of the intake port 42 and the exhaust port 44 is disposed in the first space Q1, and the other portion is disposed in the second space Q2. Therefore, in both the first space Q1 and the second space Q2, the air directly below the housing 36 can be made to flow directly upward, or the air directly above the housing 36 can be made to flow directly downward. This allows the air in the lower parts of the first space Q1 and the second space Q2 to circulate sufficiently. In addition, even if a desk (not shown) is placed next to the partition body 12, the air on the desk top is less likely to be disturbed, so documents on the top surface are less likely to fly up and conversations are less likely to be hindered.

By rotating the fan filter unit 14 shown in FIG. 1 and finely adjusting the direction in which the intake port 42 faces, the amount of air taken into each of the first space Q1 and the second space Q2 from the intake port 42 can be adjusted. Can be finely adjusted.

As shown in FIG. 4B, the blower 38 and filter 40 are housed inside the housing 36, so there is no need to provide a complex air flow path outside the housing 36, and the structure is simple and inexpensive to manufacture. In addition, the blower 38 is protected by the housing 36, so it is less susceptible to damage, and is safer than if the blower 38 were exposed.

As shown in FIG. 1, the housing 36 can be stably supported by the two support columns 20a and 20b. Further, in the first aspect, since the space R can be secured below the housing 36 sandwiched between the two pillars 20a and 20b, when the intake port 42 is directed downward, the air below the housing 36 is transferred to the intake port. 42 , and when the exhaust port 44 is directed downward, it is easy to discharge air from the exhaust port 44 toward the bottom of the housing 36 .

As shown in FIG. 1, in the first embodiment, the upper surface of the housing 36 is positioned below the upper ends of the two pillars 20a and 20b, so that the upper surface of the housing 36 can be protected by the upper ends of the two pillars 20a and 20b.

As shown in FIG. 1, the partition wall 22 extends in the same direction as the pivot center line L in a plan view and is disposed below the pivot center line L, so that air exhausted from the exhaust port 44 facing vertically downward can be smoothly blown into the indoor space S along the side of the partition wall 22. Also, although not shown, when the intake port 42 faces vertically downward, air in the indoor space S can be smoothly guided to the intake port 42 along the side of the partition wall 22.

As shown in FIG. 6, in the second embodiment, it is possible to create a flow of air flowing into the intake port 42 from the horizontal direction in the indoor space S, so that the droplets emitted by the person M due to coughing, sneezing, etc. can be efficiently removed. Can be captured well. This can reduce the risk of spreading viral infections.

5, in the second embodiment, both front-rear side surfaces of the housing 36 and both front-rear side surfaces of the partition wall 22 can be made substantially flush with each other, thereby suppressing turbulence of the airflow on both front-rear side surfaces of the partition-type air purifier 10. In addition, since the housing 36 does not protrude horizontally from the partition wall 22, it can be stored compactly in a limited space during transportation or storage.

By operating the operator 58 shown in FIG. 1 to adjust the rotation speed of the motor 56, the amount of air blown can be easily adjusted. Since the operator 58 is provided on the partition wall 22, the position of the operator 58 does not change even when the housing 36 is rotated, and stable operability can be obtained.

(Modification)
In addition, the present invention is not limited to the first embodiment, and various modifications are possible without departing from the purpose of the present invention. For example, in the first embodiment, the first side wall 46 and the second side wall 48 constituting the housing 36 are formed in a square shape, but the shape of these is not particularly limited, and they may be formed in other shapes such as a rectangle, a circle, and an ellipse. In addition, the planar shape of the filter medium 62 constituting the filter 40 may be changed to a rectangle, a circle, an ellipse, etc. according to the shapes of the first side wall 46 and the second side wall 48.

As shown in FIG. 1, in the first embodiment, the blower 38 has an operator 58, but the operator 58 may be omitted.

As shown in FIG. 7, the partition wall 22 may be provided with a display device 70 that displays various information such as a liquid crystal display device. In this configuration, various information can be provided by the display device 70. For example, information on the operating state (power ON-OFF state, wind direction, wind volume, air circulation state, time since operation started, etc.) can be provided to the operator, and information on various warnings (stay away from the housing, wear a mask, avoid the three Cs, etc.) and information on advertising can be provided to people around the partition-type air purifier 10. In addition, the means for inputting data such as images to be displayed on the display device 70 is not particularly limited, and for example, a means using a storage medium such as an SD card or a USB memory, or a communication means such as Wi-Fi may be used. In addition, the display device 70 can be provided on one side or both sides of the partition wall 22. In addition, the display device 70 can also function as an operator of the partition-type air purifier 80 by configuring it as a touch panel.

As shown in Figure 8, in the partition-type air purifier 80 according to the second embodiment, two fan filter units 14 each having a housing 36, a blower 38, and a filter 40 are provided in two levels, one above the other.

In this configuration, the direction in which the intake ports 42 and exhaust ports 44 of the two fan filter units 14 are directed can be appropriately adjusted to increase the variety of usage. For example, as shown in FIG. 9(A), in a first mode in which both intake ports 42 of the two fan filter units 14 are directed vertically upward (or vertically downward), the air can be purified by the two filters 40. In addition, in a third mode in which one exhaust port 44 of the two fan filter units 14 and the other exhaust port 44 are directed in different directions, as shown in FIG. 9(B), the effect of stirring the air in the indoor space S can be enhanced. In addition, by arranging the two exhaust ports 44 of the two fan filter units 14 facing each other, or by arranging the two intake ports 42 facing each other, a strong exhaust or intake flow can be created radially in the horizontal direction, and the air in the space facing people can be moved quickly.
