An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
Based on the front view of the air conditioner 1 in FIG. 1, the left side is defined as left, the right side is defined as right, the front side is defined as front, the back side is defined as back, the upper side is defined as upper, and the lower side is defined as lower.
As shown in FIGS. 1 to 3, the air conditioner 1 according to the present embodiment includes a housing 3, a heat exchanger 5 provided above the inside of the housing 3 and arranged so as to be inclined upward. A blower 7 provided below the inside of the housing 3 and blowing air toward the heat exchanger 5 and an electrical box 9 containing electrical components (not shown) for controlling the operation of the blower 7 and the like are provided.
The air conditioner 1 is a floor-standing air conditioner.

The housing 3 includes a frame plate 11 formed by bending a thin-walled sheet metal so that the cross section has a substantially U-shape. The housing 3 may be composed of a sheet metal forming the left side surface, a sheet metal forming the back surface, and a sheet metal forming the right side surface. A suction panel 51, a front panel 13, and a blowout panel 52 are attached to one open side surface (front side) of the frame plate 11. The frame plate 11 is provided with a top plate 15 at the top. The frame plate 11 includes a bottom plate 17 at the bottom. The suction panel 51, the front panel 13, and the blowout panel 52 may be integrated.

As shown in FIG. 1, the front panel 13 is arranged in the center of the front surface of the housing 3. A multifunctional remote controller 61 is attached to the front panel 13.

As shown in FIG. 3, the heat exchanger 5 is arranged so as to be inclined diagonally to the rear side (back side) toward the upper side in the air passage 27 which is a space between the housing 3 and the heat insulating panel 53. The wind noise with the air being blown is reduced.
Therefore, the inclination angle is determined by the depth W of the housing 3, but in general, the smaller the inclination angle of the heat exchanger 5, the smaller the wind noise. Therefore, the longer the depth W, the smaller the wind noise. In this configuration, since the electrical box 9 is arranged below the heat exchanger 5 and not on the front side, the depth W of the housing can be widened and the inclination of the heat exchanger 5 becomes large, so that heat exchange occurs. The wind noise of the wind passing through the vessel 5 is reduced.

The blower 7 is a so-called centrifugal blower. The blower 7 includes a case 29 in which a suction port 37 is formed on the front side and a blower port 35 is formed upward, an impeller 31 arranged in the case 29, and an electric motor 33 for driving the impeller 31. It is composed of.

The heat insulating panel 53 is made of Styrofoam and is composed of an upper portion 53a and a lower portion 53b.
A heat insulating body 83 is provided on the back surface 53c of the heat insulating panel 53.

Hereinafter, the primary side means the environment before the air is heat exchanged by the heat exchanger 5. Further, the secondary side means the environment after the air is heat exchanged by the heat exchanger 5.
As shown in FIGS. 3 and 4, a cover 66 is provided on the front side (front side) of the upper portion 53a of the heat insulating panel 53. On the cover 66, a nanoe generation unit 55 (sterilization unit) for supplying a mist containing nanoe (mist containing a sterilizing substance) (registered trademark) and a nanoe control unit 56 are arranged.
An eaves 67 is formed on the upper surface of the cover 66. Even when water drips onto the cover 66, the eaves 67 can prevent the water from entering the nanoe generating portion 55 in the cover 66.

A control line 81 is connected to the nanoe control unit 56. A lead-out hose 57 (lead-out member) is connected to the nano-e generation unit 55 via an O-ring 82.
That is, one end of the lead-out hose 57 is connected to the nanoe generation unit 55 via the O-ring 82. The discharge port 58, which is the other end of the lead-out hose 57, penetrates the heat insulating panel 53 and extends to the secondary side of the heat exchanger 5, and is arranged near the lower end of the air outlet 59.

As shown in FIG. 4, the heat insulating body 83 is fitted on the back surface 53c of the upper portion 53a of the heat insulating panel 53. The heat insulating body 83 projects toward the back surface side of the heat insulating panel 53. A support groove 84 is formed on the upper surface of the heat insulating body 83. The support groove 84 communicates with the opening 85 formed in the upper portion 53a of the heat insulating panel 53. The lead-out hose 57 fits into the support groove 84 of the heat insulating body 83, and after the lead-out hose 57 is arranged in the support groove 84, the lead-out hose 57 is held by the heat insulating holding member 86.
Condensation is suppressed by surrounding the lead-out hose 57 with the heat insulating body 83 and the heat insulating holding member 86.

As shown in FIG. 2, a gallery 89 is arranged at the outlet 59 of the blowout panel 52. The gallery 89 has a plurality of wind direction plates 88 extending in the left-right direction (horizontal direction), and a plurality of wind direction changing blades 90 arranged behind the wind direction plate 88 and extending in the vertical direction (height direction).
The plurality of wind direction changing blades 90 are configured to swing around the vertical axis in a state of being interlocked with each other via a motor and a swing mechanism (not shown). The discharge port 58 of the lead-out hose 57 is arranged in the space S between the lower end 90a of the wind direction changing blade 90 and the upper end 83a of the heat insulating body 83.

FIG. 5 is a plan sectional view of the outlet 59. FIG. 6 is an enlarged cross-sectional view of the discharge port 58.
The plurality of wind direction changing blades 90 are configured to swing freely with a swing angle θ in the left-right direction with the vertical axis 91 (see FIG. 6) as the rotation axis.
The discharge port 58 is not limited to being arranged near the lower end of the air outlet 59. For example, the discharge port 58 may be arranged near the side end portion or the upper end portion of the outlet 59. If the discharge port 58 is arranged near the upper end of the air outlet 59, it is preferable that the nanoe generation unit 55 and the nanoe control unit 56 are arranged at a position higher than the air outlet 59 in the housing 3. As a result, it is possible to prevent the nanoe generation unit 55 and the nanoe control unit 56 from obstructing the mainstream flow of air.

As shown in FIG. 5, the upper end 83a of the heat insulating body 83 extends to the rear side (inside) of the second wind direction changing blade 90 from the left.
As shown in FIG. 6, the discharge port 58 of the lead-out hose 57 extending to the upper end 83a of the heat insulating body 83 swings around the vertical axis 91 with a swing range of a swing angle θ. Occasionally, it is tilted outside the swing range at an angle α so that the nanoe can be sufficiently diffused.

The wind direction changing blade 90 is swingable by 30 degrees in each of the left and right directions starting from the vertical axis 91. That is, the swing angle θ is set to 60 degrees.
The angle α of the discharge port 58 is set to 45 degrees.
The wind direction changing blade 90 swings in the left-right direction by an angle that is half of the swing angle θ. The angle α of the discharge port 58 is set to be an angle larger than an angle of half of this swing angle θ.
When the angle α of the discharge port 58 is larger than the angle of half of the swing angle θ, it is possible to prevent the air blown out from the outlet 59 through the wind direction changing blade 90 from entering the discharge port 58. .. Therefore, the nanoe generated from the discharge port 58 can be stably supplied to the room by attracting the air after heat exchange blown out from the air outlet 59.

The wind direction changing blade 90 swings within the range of the swing angle θ. As shown in FIG. 6, the discharge port 58 is arranged outside the swing range of the wind direction changing blade 90.
In the present embodiment, as shown in FIG. 6, the wind direction changing blade 90 and the lead hose 57 are configured to partially overlap in a plan view, but the present invention is not limited to this configuration and is 90 in a plan view. And the lead-out hose 57 may be arranged so as not to overlap. In this case, it is preferable that the extension line of the discharge port 58 in the blowing direction is outside the swing range of 90. As a result, it is possible to prevent the nano-emist discharged from the discharge port 58 from entering the discharge port 58.

The vertically extending portions of the lead-out hose 57 are arranged along the vertical axis 91. Air turbulence occurs inside the swing range of the wind direction changing blade 90, but air turbulence is small outside the swing range because the influence of the swing operation of the wind direction changing blade 90 is small. Moreover, since the discharge port 58 is located in the space S shown in FIG. 3, it is located at a position where there is less turbulence in the air.

Next, the action of this embodiment will be described.
In the air conditioner 1 according to the present embodiment, when the electric motor 33 of the blower 7 is driven, air is sucked from the suction port 37 of the blower through the suction panel 51 and blown upward from the blower port 35. Here, the amount of air sucked into the suction port 37 from the vicinity of the upper part of the suction port 37 (see FIG. 3) is smaller than the amount of air sucked into the suction port 37 from the vicinity of the lower part thereof (see FIG. 3). Is common, and by arranging the electrical box 9 in the portion where the intake air amount is small in this way, the decrease in the intake air amount is suppressed to an extremely small level.

Then, the air blown from the blower port 35 passes through the heat exchanger 5, is guided by the wind direction changing blade 90, and is blown from the blowout port 59 of the blowout panel 52. The air guided by the wind direction changing blade 90 is suppressed from entering the discharge port 58, and the nanoe diffused from the discharge port 58 is blown out from the outlet 59.
In the present embodiment, the unit that releases the nanoe mist by the nanoe generating unit has been described, but the present invention is not limited to this, and any configuration may be used as long as it releases a mist containing a substance having a sterilizing and deodorizing effect. ..

The connected lead-out hose 57 (lead-out member) was placed inside the housing 3 through the heat insulating panel 53, and the discharge port 58 was placed near the lower end of the air outlet 59.
According to this, the discharge port 58 is provided in the vicinity of the lower end portion of the outlet 59, which is located close to the nanoe generation portion 55 in the outlet 59, and the outlet hose 57 can be shortened. Therefore, nanoe can be released in a short time.
The lower end of the air outlet 59 is a position where the air flow is less turbulent, and the nanoe is discharged to this position. Therefore, the nanoe smoothly diffused into the space S is stably supplied to the room.

Further, a heat insulating body 83 is provided on the surface of the heat insulating panel 53 on the heat exchanger 5 side, a lead-out hose 57 (lead-out member) is provided through the heat insulating body 83, and the upper end 83a of the heat insulating body 83 is an outlet. It extends to the vicinity of the lower end of 59. The upper end 83a (see FIG. 5) of the heat insulating body 83 extends into the space S.

According to this, the space S between the lower end of the wind direction changing blade 90 and the upper end of the heat insulating body 83 has less air turbulence, and nanoe can be stably supplied to the room by attraction.

Further, the wind direction changing blade 90 swings within the range of the swing angle θ. In the present embodiment, as shown in FIG. 6, the discharge port 58 faces the outside of the swing range of the wind direction changing blade 90.
Air turbulence increases inside the swing range of the wind direction changing blade 90.
According to this, the turbulence of air is reduced outside the swing range of the wind direction changing blade 90, and it becomes easy to stably supply nanoe by attraction. Further, it is possible to prevent the air after heat exchange guided by the wind direction changing blade 90 from entering the discharge port 58.

Further, according to the present embodiment, the angle α of the discharge port 58 is 45 degrees, and the angle α of the discharge port 58 is larger than 30 degrees, which is a half angle of the swing angle θ. It is said to be an angle. That is, the discharge port 58 was arranged so as to be tilted toward the outside of the swing range of the wind direction changing blade 90.
According to this, since the discharge port 58 is arranged at an angle toward the outside of the swing range of the wind direction changing blade 90, it is possible to prevent the air after heat exchange guided by the wind direction changing blade 90 from entering the discharge port 58. .. Then, nanoe can be stably supplied by attraction.

Further, according to the present embodiment, the nanoe generation unit 55 and the nanoe control unit 56 are integrally provided on the surface of the upper portion 53a of the heat insulating panel 53. The space on this surface was a dead space in the past, but the space can be effectively used.

Further, according to the present embodiment, the surface of the upper portion 53a of the heat insulating panel 53 is arranged at a position close to the air outlet 59 inside the blowout panel 52. As shown in FIG. 3, since the discharge port 58 of the lead-out hose 57 faces the lower end of the outlet 59, the length of the lead-out hose 57 can be shortened, and the nanoe generated by the discharge can be discharged in a short time.

Further, since the nanoe generating portion 55 is provided on the surface of the upper portion 53a of the heat insulating panel 53, the primary side duct supplied to the nanoe generating portion 55 becomes unnecessary, and the number of parts can be reduced.

Although the present invention has been described above based on the present embodiment, it goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist of the present invention.
