Description

[Technical field]

[0001] The present application discloses an air direction adjustment device for an air conditioning outlet and an air purification sheet thereof. [Background technology]

[0002] Air conditioners are installed in various buildings such as buildings, stores, hospitals, and houses to condition the air inside the buildings. There are three types of air conditioners: those that are embedded in the ceiling or wall, those that are suspended from the ceiling, and those that are installed on the wall, but they all have in common the fact that they are equipped with an air conditioning outlet that blows conditioned air into the room.

[0003] However, since the specific gravity of air is inversely proportional to the temperature, warm air accumulates in the upper part of the room. Cold air accumulates in the lower part of the room. Therefore, for example, when performing cooling operation, an air conditioner blows cold air from an air conditioner outlet toward the lower part of the room so that the warm air that accumulates in the upper part of the room can be efficiently sucked in and conditioned. Therefore, in order to prevent the cold air blowing out from the air conditioner outlet from hitting people in the room, for example, a device for adjusting the air direction of the air conditioner outlet, as shown in Patent Document 1, is commercially available.

[0004] [Patent Document 1] Utility Model Registration No. 3114170 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, there has been growing interest in infection prevention measures for airborne viruses and various other air purification methods. However, for example, viruses are smaller than pollen or fine particulate matter (PM). Therefore, viruses cannot be captured by air conditioner filters. Furthermore, if a filter capable of capturing viruses is attached to the air conditioner's intake or exhaust port, the ventilation rate is significantly reduced, and the performance of the air conditioner is greatly reduced.

[0006] Therefore, the present application discloses an air direction adjustment device for an air conditioning outlet that is capable of purifying air while suppressing a decrease in the performance of an air conditioner, and an air purification sheet for the device. [Means for solving the problem]

[0007] In order to solve the above problems, in the present invention, a purification layer section made of multiple layers of porous sheets carrying air purifying components is provided on the air conditioning outlet side of the face plate of the air direction adjustment device that receives the air blown out from the air conditioning outlet.

[0008] In detail, the present invention is an air direction adjustment device for an air conditioning outlet, which is arranged in front of the air conditioning outlet from which conditioned air is blown out to an air conditioner, and comprises a panel section which receives the air blown out from the air conditioning outlet, an attachment section which attaches the panel section to the front of the air conditioning outlet, and a purification layer section on the air conditioning outlet side of the panel section, which is made up of multiple layers of porous sheets carrying air purifying components.

[0009] With such an airflow direction adjustment device, the air blown out from the air conditioning outlet flows along the surface of the panel part that adjusts the airflow direction on the air conditioning outlet side while coming into contact with the purification layer part, so the flow of the air blown out from the air conditioning outlet is not easily obstructed. Therefore, it is possible to purify the air while suppressing a decrease in the performance of the air conditioner.

[0010] The purification layer portion has two or more layers of perforated sheets at least on the air conditioning outlet side of the face plate portion. The purification layer may be formed by wrapping a single sheet around the face plate so that the purification layer is uniform. This makes it easy to provide the purification layer.

[0011] The porous sheet may also be a paper sheet carrying an air purifying component, which allows the sheet to be disposed of as a combustible material after use.

[0012] The porous sheet is a sheet having holes regularly arranged, and the purifying layer portion may be arranged such that the holes of adjacent sheets in the stacking direction are arranged at different positions when viewed along the stacking direction, whereby the air purifying component carried on the porous sheet comes into contact with the air, and the air purifying component acts on the air more reliably.

[0013] The present invention may also be an air purification sheet for an air direction adjustment device for an air conditioning outlet, which is a porous sheet carrying an air purification component for forming a purification layer portion provided in the air direction adjustment device for an air conditioning outlet described in any of the above. Effect of the Invention

[0014] The above-mentioned air direction adjustment device for an air conditioning outlet and its air purifying sheet are capable of purifying the air while preventing a decrease in the performance of the air conditioner. [Brief description of the drawings]

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes an embodiment of the present invention. The embodiment described below is one aspect of the present invention, and the technical scope of the present invention is not limited to the following embodiment.

[0017] Fig. 1 shows an example of the installation state of an air direction adjustment device 3 that adjusts the direction of air blown out from an air conditioning outlet 2 of an air conditioner 1. As shown in Fig. 1, the air direction adjustment device 3 is disposed in front of the air conditioning outlet 2 from which conditioned air is blown out to the air conditioner, and includes a wing plate 4 (an example of a "face plate portion" as referred to in this application) that receives the air blown out from the air conditioning outlet 2, and an arm 5 (an example of an "attachment portion" as referred to in this application) for attaching the wing plate 4 to the front of the air conditioning outlet 2.

[0018] FIG. 2 is a perspective view of the airflow direction adjustment device 3. The wing plate 4 is made of plastic or other synthetic resin, and its overall shape is a nearly rectangular shallow container. The wing plate 4 has walls 7L, 7S, 7S erected at right angles to the main surface 6 at both longitudinal ends and the remaining side edge, except for one side edge of the main surface 6. The wall 7L is a wall extending along the long side of the rectangular wing plate 4 as a whole. The walls 7S, 7S are also wall extending along the short side of the wing plate 4. The wing plate 4 has a curved portion 8 that is continuous with the main surface 6 and curves gently at one side edge where the walls 7L, 7S, 7S are not formed.

[0019] On the upper surface of the main surface portion 6, reinforcing ribs 9, 9 are provided at equal intervals along the longitudinal direction of the main surface portion 6. are provided, dividing the wing plate 4, which has an overall shallow container shape, into three sections 10L, 10C, and 10R. Each reinforcing rib 9, 9 is provided with a hinge 11 for attaching the arm 5 to the wing plate 4 so as to be rotatable about one axis. In FIG. 2, the upper side of the arm 5 is omitted, but the arm 5 is attached near the boundary between the ceiling and the air conditioner 1 as shown in FIG. 1. The wall sections 7S, 7S and the reinforcing ribs 9, 9 are each provided with claws 13F, 13R for fixing the heat insulating mat by sandwiching it between the main surface section 6. The heat insulating mat is attached when it is desired to prevent condensation on the underside of the wing plate 4.

[0020] FIG. 3 is a diagram showing an example of an air purifying sheet 20 attached to the airflow direction adjustment device 3. The air purifying sheet 20 is a porous sheet having a rectangular sheet body 21 and air holes 22 arranged lengthwise and widthwise on the sheet body 21. The sheet body 21 is a sheet that supports air purifying components. Examples of the air purifying components supported by the sheet body 21 include metal ions with deodorizing, antibacterial, and antiviral properties, components of Abies sachalinensis that are believed to have deodorizing capabilities and the ability to remove nitrogen dioxide (NO2), an air pollutant, and various other components. Sheets made of various materials can be used as the sheet body 21 that supports these air purifying components. For example, a paper sheet in which metal ions are supported on the surface of modified cellulose is suitable as the sheet body 21. If the sheet is made of paper, the used sheet can be disposed of as combustible material, thereby reducing the impact on the natural environment.

[0021] The ventilation holes 22 arranged vertically and horizontally in the sheet body 21 are circular holes with a diameter of about 3 to 5 mm. The ventilation holes 22 are arranged regularly vertically and horizontally as shown in Fig. 3. The distance between each ventilation hole 22 is about 1 to 3 mm. The ventilation holes 22 are not limited to being regularly arranged vertically and horizontally, and may be arranged, for example, such that columns diagonally intersect with specific rows.

[0022] 4 is a diagram showing the air direction adjustment device 3 with the air purification sheet 20 attached to the wing plate 4. The air purification sheet 20 is wrapped around the wing plate 4 of the air direction adjustment device 3, for example, as shown in FIG. 4. Because the air direction adjustment device 3 is provided with two arms 5, when wrapping the air purification sheet 20 around the wing plate 4, as shown in FIG. 4, the air purification sheet 20 is divided into three parts so as not to interfere with the arms 5. The air purification sheet 20 is then wrapped around the wing plate 4 at positions corresponding to the sections 10L, 10C, and 10R. The ends of the air purification sheet 20 wrapped around the wing plate 4 are fixed with, for example, adhesive tape.

[0023] FIG. 5 is a cross-sectional view of the airflow direction adjustment device 3 taken along the line AA in FIG. 4. The block arrows in FIG. 5 and the dashed arrows in the dashed frame in the partially enlarged view are diagrams showing the flow of air blown out from the air conditioning outlet 2 of the air conditioner 1. As described above, the airflow direction adjustment device 3 is disposed in front of the air conditioning outlet 2, and the wing plate 4 receives the air blown out from the air conditioning outlet 2. The wing plate 4 has a flat plate-like main surface portion 6 forming a main portion, a wall portion 7L erected from the edge of the main surface portion 6, and a curved portion 8 that is continuous with the main surface portion 6 and curves gently, so that an inner space 4S is formed inside the air purification sheet 20 wrapped around the wing plate 4. The air purification sheet 20 is wrapped around the wing plate 4 so as to be doubled at least on the air conditioning outlet 2 side of the wing plate 4, as shown in FIG. 5. Therefore, the air purification sheet 20 has a two-layer structure on the air conditioning outlet 2 side of the wing plate 4. The air purifying sheet 20 is suspended between the apex of the wall portion 7L and the apex of the curved portion 8 on the air conditioning outlet 2 side of the wing plate 4. Therefore, on the air conditioning outlet 2 side of the wing plate 4, the double-layered air purifying sheet 20 has a slight gap between them, and as shown in the partially enlarged view of FIG. The air that has passed through the holes 22 passes through. Therefore, the wing plate 4 of the air purifying sheet 20 on the air conditioning outlet 2 side forms a purification layer portion 4J that purifies the air passing through the vent hole 22 with the air purifying component carried by the sheet body 21. Also, as shown in the partial enlarged view of FIG. 5, the vent holes 22 of the air purifying sheets 20 adjacent to each other in the stacking direction are arranged at different positions when viewed along the stacking direction. Therefore, as shown in the partial enlarged view of FIG. 5, when the air blown from the air conditioning outlet 2 to the air direction adjustment device 3 passes through the vent holes 22 of the double air purifying sheet 20 and enters and leaves the inner space 4S, it does not pass through each vent hole 22 in a straight line, but passes through each vent hole 22 in a meandering manner. Therefore, the air passing through the vent hole 22 enters and leaves the inner space 4S while reliably contacting the surface of the sheet body 21 on which the air purifying component is carried. As a result, the air purifying component carried by the sheet body 21 comes into contact with the air, and the air purifying component acts on the air more reliably.

[0024] Since the air conditioner 1 has such a purification layer 4J on the air conditioner outlet 2 side of the wing plate 4, it can purify the air blown out from the air conditioner outlet 2. In addition, since the purification layer 4J is formed in a form almost similar to the plate-shaped main surface portion 6 that rectifies the air blown out from the air conditioner outlet 2, the air conditioner 1 does not obstruct the flow of air blown out from the air conditioner outlet 2 compared to a form in which the air conditioner outlet 2 and the intake port are covered with a sheet-shaped filter. Therefore, it is possible to purify the air while suppressing a decrease in the performance of the air conditioner 1. In addition, for example, if the air purification sheet 20 has metal ions having deodorizing, antibacterial, and antiviral properties supported on the sheet main body 21 as air purification components, it is possible to inactivate viruses in the air while suppressing a decrease in the performance of the air conditioner 1.

[0025] The airflow direction adjustment device 3 is not limited to the above-mentioned embodiment. The airflow direction adjustment device 3 may be, for example, a device in which the air purification sheet 20 is fixed to a frame-like object in two or more layers and attached to the air conditioner outlet 2 side of the wing plate 4. The airflow direction adjustment device 3 may be, for example, a device in which the air purification sheet 20 is wrapped around the wing plate 4 so that the air purification sheet 20 is in three or more layers on the air conditioner outlet 2 side of the wing plate 4. The airflow direction adjustment device 3 may be arranged such that the air vents 22 of the air purification sheets 20 adjacent to each other in the stacking direction are located at the same position when viewed along the stacking direction. The airflow direction adjustment device 3 may be changed to various other forms in which the air purification sheet 20 is in multiple layers on the air conditioner outlet 2 side of the wing plate 4. The airflow direction adjustment device 3 is not limited to the shape of the wing plate 4 shown in FIG. 2, and may be any form that can receive the air blown out from the air conditioner outlet 2 with a plate-shaped surface.
