The air-conditioning apparatus according to the first embodiment is a circulation circulator that is attached to a ceiling or a wall of a room and circulates air in the room. Fig. 1 shows an example in which an air conditioner is attached to a ceiling 26 which is a horizontal mounting surface. If the mounting surface is a vertical wall, the air conditioning system It is set in a posture inclined by 90° from the example shown in Fig. 1. In addition, the term indicating the direction used in the following description is based on the direction in which the posture is set as shown in FIG.

The air conditioning apparatus includes a body 1, a multi-blade air blower 2, a decorative grille 6, and a discharge unit 5. Fig. 2 is a view of the air conditioner of the first embodiment as seen from above. Fig. 3 is a view showing the air conditioner of the first embodiment as seen from below, showing a state in which the decorative grille 6 has been removed.

The body 1 is in the shape of a box formed of a resin. As shown in FIG. 3, the opening 27 is formed on one side of the body 1. The opening 27 is divided into an inlet 27a for taking in air into the inside of the body 1, and a discharge port 27b for discharging air from the inside of the body 1. Inside the main body 1, as shown by an arrow in Fig. 1, a flow path for connecting the inlet 27a and the discharge port 27b is formed. A flange 1a protruding around the opening 27 is formed in the body 1. In other words, the flange 1a protrudes in parallel with the ceiling 26 which is the mounting surface. At the upper portion of the body 1, there is included a terminal block 8 which is of a rotary configuration and which can be easily connected to an external power supply line, and a control circuit 10 in the circuit housing case 9.

The multi-blade blower 2, which is a blower, is disposed in a flow path formed inside the body 1. The multi-blade air blower 2 is rotated by a fan 3 coupled to a drive shaft of a motor 7, and an air flow from the intake port 27a to the discharge port 27b is generated in the flow path. The multi-blade air blower 2 includes a fan casing 4 that houses the fan 3. Fig. 4 is a perspective view of the fan casing 4 of the first embodiment. An open fan casing 4 for taking in air.

Fig. 5 is a side view of the air conditioner of the first embodiment. The decorative grille 6 is a plate-shaped member that faces the opening 27 and the flange 1a. Decorative grid 6 It is configured to be separated from the opening 27 and the flange 1a. The decorative grille 6 functions to improve the design of the air conditioner and prevent the foreign matter from entering the fan 3 in a closed state. Decorative grille 6 is a one-piece molded body of resin. The outer side surface 29 of the decorative grid 6 which is opposite to the opening 27 and the flange 1a facing the back surface 28 is formed as a flat surface.

As shown in FIG. 5, the decorative grille 6 is fixed to the main body 1 by fitting the shaft 6a and the claw 6b formed in the decorative grill 6 to the bearing portion 1d and the claw 1e formed in the main body 1, respectively. Fig. 6 is a view showing a state in which the decorative grille is opened in the air-conditioning apparatus according to the first embodiment. By removing the claws 6b of the decorative grille 6 from the claws 1e of the main body 1, as shown in Fig. 6, the decorative grille 6 can be rotated about the shaft 6a and the bearing portion 1d, and the decorative grille 6 can be opened.

Returning to Fig. 1, in the air conditioner, a rib which divides the space between the opening 27 and the flange 1a and the decorative grid 6 into the first region 31 and the second region 32 as viewed from a direction perpendicular to the opening 27 is provided. 30. The first region 31 is opposed to the inlet 27a of the body 1. The second region 32 is opposed to the discharge port 27b of the body 1.

Fig. 7 is a perspective view of the air conditioner of the first embodiment as seen from the lower side, showing a state in which the decorative grille 6 has been removed. Fig. 8 is a perspective view of the decorative grill 6 of the first embodiment as seen from the side of the facing surface 28. The rib 30 provided in the air conditioner is a flange rib 1f (see FIG. 7) formed on the flange 1a of the main body 1, and a grid rib 6c formed on the opposing surface 28 of the decorative grid 6 (see FIG. 8). The casing rib 4c formed in the fan casing 4 is combined. More specifically, in a region opposed to the opening 27, the grid rib 6c overlaps with the outer casing rib 4c in the height direction, and the flange rib 1f is provided on both sides thereof. The space between the opening 27 and the flange 1a and the decorative grid 6 is divided into the ribs 30 of the first region 31 and the second region 32. With this configuration, the rib 30 becomes the rib 30 extending from the end portion of the flange 1a (the decorative grill 6) to the other end portion. Thereby, both the first region 31 and the second region 32 include at least the end surface region of the flange 1a (the decorative grid 6).

Fig. 9 is an enlarged view of a portion of the flange rib 1f of the first embodiment. The rib 30 is a portion that is close to the end of the outer circumference of the decorative grid 6, that is, the flange rib 1f of the present embodiment is separated from the center side toward the end side from the center side of the rib 30 and goes to the second portion. The partition surface 33 on the side of the region 32 is formed on the surface facing the second region 32 side. For example, in the case where the width of the flange 1a is 25 mm, the partition surface 33 is formed in a range of 12.5 mm from the end portion. The partition surface 33 is set to an angle of 30° with respect to the surface of the flange rib 1f facing the first region 31 side. In the first embodiment, the flange rib 1f is widened in width from the center side to the end side of the rib 30, thereby forming the partition surface 33. The portion forming the partition surface 33 has a triangular prism shape.

Fig. 10 is a partially enlarged cross-sectional view showing an enlarged outer peripheral portion of the second region 32 between the flange 1a and the decorative grid 6 of the first embodiment. As shown in Fig. 10, the inclined surface 34 that approaches the decorative grid 6 toward the outer circumference of the flange 1a is formed on the flange 1a of the second region 32. Further, in a portion of the decorative grid 6 facing the inclined surface 34, a projection 6d extending in parallel with the outer circumference of the decorative grid 6 is formed (see also Fig. 8). Further, the inclined surface 34 may be formed also on the flange 1a of the first region 31.

For example, in the case where the width of the flange 1a is 25 mm, and the interval between the outer peripheral end of the flange 1a and the outer peripheral end of the decorative grid 6 is 11 mm, the inclination angle of the inclined surface 34 is set to 12°, and the outer peripheral side of the inclined surface 34 is provided. Port and flange 1a The outer peripheral end was set to 2 mm, and the projection 6d was formed at a position of 20 mm from the outer peripheral end of the decorative grill 6 to the inner side at a height of 3 mm.

In the air conditioner, the fan 3 is rotated by the operation of the multi-blade air blower 2, air is taken into the inside of the main body 1 from the intake port 27a, and air is discharged from the discharge port 27b through the flow path inside the main body 1. Thereby, air is sucked into the first region 31 from between the flange 1a and the decorative grill 6, and air is blown from the second region 32 between the flange 1a and the decorative grill 6. In other words, the outer peripheral portion of the first region 31 between the flange 1a and the decorative grill 6 serves as a suction port for taking in air, and the outer peripheral portion of the second region 32 serves as an air outlet for blowing air. Therefore, in the air conditioner, the suction port and the air outlet are adjacent to each other via the rib 30.

Here, since the partition surface 33 is formed in the rib 30 (the flange rib 1f) which is the boundary between the suction port and the air outlet, the air blown along the rib 30 is in the direction away from the first region 31 (Fig. 9). The direction indicated by the arrow X is guided. Therefore, it is difficult to cause a short circuit in which the air blown from the second region 32 is immediately sucked from the first region 31.

In this manner, since the suction port is adjacent to the air outlet in the space between the flange 1a and the decorative grill 6, the occurrence of a short circuit can be suppressed, so that the outer side surface 29 of the decorative grill 6 does not have a suction port or a blow port. . Further, it is not necessary to provide the unevenness on the outer surface of the decorative grid 6 in order to suppress the occurrence of a short circuit, and the outer surface 29 can be made a flat surface. Thereby, the design of the air conditioner can be improved. Moreover, since the outer side surface 29 is made into a flat surface, since the processing cost can be suppressed, the manufacturing cost of an air-conditioning apparatus can be suppressed.

Further, when the air blown from the gap between the flange 1a and the decorative grid 6 comes into contact with the ceiling 26, the ceiling surface may become dirty. On the other hand, in this first In the embodiment, the inclined surface 34 formed on the flange 1a is guided by the air blown from the gap between the flange 1a and the decorative grid 6 in the direction away from the ceiling 26 (the direction indicated by the arrow Y in Fig. 10). Lead, so the ceiling 26 is difficult to get dirty. Further, by the projections 6d formed on the opposing faces 28 of the decorative grille 6, the flow of the air is once directed toward the inclined surface 34, whereby the air guiding effect by the inclined surface 34 can be more reliably exhibited. Further, since it is not necessary to prevent the air blown from the air-conditioning apparatus from coming into contact with the ceiling 26, the air outlet is formed on the outer side surface 29 of the decorative grill 6, so that the design of the air-conditioning apparatus can be improved. Further, when the inclined surface 34 is formed also on the flange 1a located in the first region 31, it is possible to prevent the ceiling surface from becoming dirty due to the contact of the air taken in by the air conditioner with the ceiling 26.

The air-conditioning apparatus is fixed to the ceiling 26 by fixing screws such as wood screws at four or more positions by the fixing screw mounting portion 1b (see FIG. 3) provided at eight places of the flange 1a.

Fig. 11 is a perspective view of the dust filter 23 of the first embodiment. As shown in FIGS. 3 and 7, the dust filter 23 is provided to cover the inlet 27a of the body 1. The fixing portion 4a and the claw hook portion 4b for fixing the dust removing filter 23 are formed in the fan casing 4. The dust removing filter 23 is fixed to the fan casing 4 by fixing and fitting the fixing portion 23a and the claw portion 23b of the dust removing filter 23 to the fixing portion 4a and the claw hook portion 4b, respectively. The grip portion 23c that can be gripped during disassembly and assembly is formed in the dust filter 23.

Further, the discharge unit 5 includes the deodorizing filter 12 and is the third frame. Deodorizing the filter cover 21.

The discharge electrode 16 is formed by using, for example, a conductor such as tungsten as a material, and having a wire shape in a cross-sectional shape of a circular shape or a rounded rectangle, and having sufficient strength. Further, as the material of the electrode 17 such as stainless steel or the like, a conductive resin containing carbon or the like and having a resistance value of about 10 ⁴ Ω/cm or a resin to which metal plating is applied may be used. It is preferable that the discharge electrode 16 and the counter electrode 17 are made of a material which is difficult to be rusted by water in order to be washable.

When a metal plate-shaped member is used for the counter electrode 17, it is preferable to form a shape in which a plurality of flat electrodes are arranged in parallel by performing cutting and bending as shown in Fig. 14.

As shown in FIG. 15, the discharge portion 13 has a structure in which the discharge electrode 16 and the counter electrode 17 are arranged in parallel and are alternately arranged on the discharge electrode 16 and the counter electrode 17.

The discharge electrode 16 is hooked to the discharge electrode hook portion 15a provided in the discharge portion lower cover 15 formed of an insulating material as shown in Figs. 17 and 18, and is applied to both ends of the discharge electrode 16 by the spring 20. The state of the tension is hooked and fixed to the metal terminal 35 disposed on the lower cover 15 of the discharge portion, thereby preventing slack. The lower cover opening 15b is formed in the discharge portion lower cover 15 as a first opening through which air passes.

In order to insulate the discharge electrode 16 and the opposite electrode 17 disposed as described above, as shown in Fig. 19, the discharge electrode hook right member 18 formed of an insulating material and the discharge electrode hook left member 19 are disposed in the discharge. The lower cover 15, and the opposite electrode 17 is disposed thereon, as shown in Fig. 20, The discharge portion upper cover 14 formed by the edge material is joined. The upper cover opening 14d is formed in the discharge portion upper cover 14 as a second opening through which air passes. Further, a through opening 14e for penetrating the deodorizing filter contact portion 17a of the opposing electrode 17 is formed in the discharge portion upper cover 14. Further, the deodorizing filter contact portion 17a is also penetrated from the upper cover opening 14d.

As shown in Fig. 21, the deodorizing filter 12 is provided on the discharge portion upper cover 14, and is fixed by the deodorizing filter cover 21 of the third frame as shown in Fig. 13. Further, a filter cover opening 21d as a third opening through which air passes is formed in the deodorizing filter cover 21. As shown in Fig. 22, the deodorizing filter contact portion 17a formed in the opposing electrode 17 constituting the charging portion penetrates the through opening 14e formed in the discharge portion upper cover 14, and protrudes to the deodorizing filter cover 21 side. Thereby, it comes into contact with the deodorizing filter 12 which comprises a dust collecting part. Thereby, the deodorizing filter 12 has the same potential (the GND side) as the opposing electrode 17. According to this configuration, the fine particles charged in the discharge portion 13 can be efficiently collected in the deodorizing filter 12. Further, by combining the respective frames, the deodorizing filter contact portion 17a is in contact with the deodorizing filter 12 inside the discharge unit 5, so that it can be suppressed as compared with the case of electrically contacting the outside of the discharge unit 5 The number of components is reduced while manufacturing costs are suppressed.

The deodorizing filter 12 is made of an aluminum alloy or ceramic in which a plurality of openings are present in a substrate, and is coated with a conductive catalyst such as manganese dioxide on the surface.

As shown in Fig. 23, Fig. 24, and Fig. 25, the deodorizing filter cover 21 is a fixing portion 21b for fitting the claw 21a to the claw of the claw 14a of the discharge portion upper cover 14, and deodorizing the filter cover 21. 21c is separately slidably fixed to the fixing portions 14b and 14c of the discharge portion upper cover 14, and is easily detachable. according to In this manner, the deodorizing filter 12 can be washed with water by using an aluminum alloy or a ceramic material on the substrate of the deodorizing filter 12, and can be easily disassembled, whereby the deodorizing filter 12 can be taken out, and the deodorizing filter 12 can be easily washed away.
