Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner including a dehumidifier and a cold / hot air fan.
[0002]
[Prior art]
As shown in FIGS. 6 and 7, this type of conventional air conditioner is provided with an opening 4 of an outer box 3 on the top surface of the main body 1, at the top of the blower opening 2. A rotating upper and lower airflow direction vane 5 that is flush with the opening and has shafts on the left and right is formed. On the front upper portion of the outer box 3, a blow grill 6 formed of a horizontal beam and a vertical beam is formed. Was configured and communicated with the air blowing port 2.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, when the air blown from the fan 7 is blown upward, the air blown from the blower opening 2 is sent straight to the opening 4 of the outer box by raising the up-and-down airflow direction vane 5. In the case of blowing forward, the opening 4 is closed so that the up / down wind direction changing blade 5 is flush with the opening 4 of the outer box, and the wind blown from the blowing port 2 is blown. It was bent and sent to the blow grill 6 and blown forward.
[0004]
However, in this case, the opening 4 cannot always be sealed, so that there is a wind leak from the gap between the opening 4 and the blade 5, resulting in a loss. Further, when the outer box corner 8 between the opening 4 on the top of the outer box and the blow-out grill 6 on the front surface, for example, tilts the wind direction changing blade 5 at 45 degrees, it becomes an obstacle in the blowing direction, The direction could not be changed continuously from top to front.
[0005]
In addition, since it was a horizontal blowout forward, it was not possible to spray shoes or laundry placed on the floor in front of the air conditioner, or low places where moisture could accumulate, such as the bottom of a closet or a shoe rack.
[0006]
Further, in the conventional configuration, when blowing forward, the wind at the upper part of the air blowing port 2 is aligned with the direction of the up-and-down air direction changing blade 5 and tries to blow in the horizontal direction. The wind blown out from the front blower opening 2 was blown upward from the blowout grill 6 as a result, and as a result, the blown air tended to be slightly upward.
[0007]
Further, in the conventional configuration, when the fan 7 is arranged as shown in FIG. 6, due to the characteristics of the fan 7, there is a tendency that the wind direction tends to be shifted to the left from the front, and the air does not blow out almost straight forward.
[0008]
The present invention solves such a conventional problem, and reduces the air leakage loss as much as possible and rotates the up / down air direction changing blade to continuously change the blowing direction from the upper side to the lower front side. An object of the present invention is to provide an air conditioner capable of performing the above.
[0009]
[Means for Solving the Problems]
The invention according to claim 1 for solving the above-mentioned problem comprises a blow-off grill having a cross rail on the front surface of the concave blower opening portion formed on the top surface portion of the outer box constituting the outer shell of the main body, In addition, a plate-shaped vertical airflow direction changeable blade having left and right shaft portions is disposed above the blower opening, and the front end of the vertical airflow direction change blade is the air blower. An air conditioner that is positioned above the outlet grill with the upper part of the mouth closed, and that is configured in series with the outlet grill. be able to.
[0010]
In the invention according to claim 2, the bottom surface of the blower opening provided on the top surface of the outer box is disposed above the lowermost part of the blowout grill, and the bottom front edge of the blower blower part and the lowest part of the blowout grille are It is the structure which connected by the inclined surface, and can provide the ventilation of the front diagonally downward blowing more efficiently.
[0011]
According to a third aspect of the present invention, the vertical rail of the blow grill is formed into a substantially triangular shape connecting the uppermost portion and the lowermost portion of the horizontal grill of the blow grill and the inclined surface. Misalignment can be prevented.
[0012]
As described above, the front end of the up / down wind direction changing blade is disposed above the blow-out grill, so that in the case of blow-out of the front, the wind leakage loss can be reduced and blown out effectively.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
(Embodiment 1)
FIG. 1 is a front view showing an appearance of a main body 11 of an air conditioner according to the present embodiment. A blow grill 12 formed of a horizontal beam and a vertical beam is formed on the upper front of the main body 11 and an upper and lower airflow direction is changed on the upper portion. A blade 13 is formed.
[0015]
FIG. 2 is a longitudinal sectional view of the main blower portion of the main body 11 as viewed from the front. A centrifugal fan 15 is disposed inside the fan case 14, and the fan case 14 is connected to the blower port portion 16 at the upper portion. 16a communicates.
[0016]
FIG. 3 is a longitudinal sectional view of the front portion of the main body 11 as seen from the right side. The outer box on the front surface of the blower port portion 16 has a blow grill 12 formed of a horizontal beam 12a and a vertical beam 12b. Above the blower port portion 16, there is a vertical wind direction changing blade 13 that can be rotated by the left and right shaft portions 17, and the front end 13 a of the upper end of the blower port portion 16 is blocked by the vertical wind direction changing blade 13. In this state, it is arranged to be above the blowout grill 12.
[0017]
In the above configuration, when blowing the air from the fan 15 upward, the air blown from the air blowing port 16a is sent straight upward and suspended upward by rotating the up-and-down air direction changing blade 13 to stand. It is possible to effectively wind the washed laundry.
[0018]
Further, in the case of horizontal front blowing or front oblique upper blowing, the vertical wind direction changing blade 13 is rotated to be directed to an appropriate angle, the wind blown from the air blowing port 16a is applied to the blade 13, and the wind direction is bent, The air can be blown in a target direction through the gap between the blowout grill 12 and the blade 13.
[0019]
Further, in the case of the front obliquely downward blowing, as shown in FIG. 3, the up / down air direction changing blade 13 is rotated to close the rear end of the up / down air direction changing blade 13 as the same surface as the outer box, and slightly downward. By setting, the wind blown upward from the blower opening 16 a once hits the up-and-down wind direction changing blade 13, but the front end 13 a of the blade 13 is configured in series above the blow-out grill 12. The wind is blown obliquely downward according to the angle of the up-and-down wind direction changing blades 13, and it is easy to accumulate moisture such as shoes and laundry placed on the floor surface in front of the integrated air conditioner, and the lower part of the closet and the shoebox Can be sprayed on low places.
[0020]
(Embodiment 2)
FIG. 4 is a longitudinal cross-sectional view of the air blowing port portion, where the bottom surface 16b of the air blowing port portion 16 is disposed above the lowermost portion 12c of the blowout grill 12, and the front edge of the bottom surface of the blower opening portion and the blowout grill 12 The lowest part is connected by an inclined surface 18.
[0021]
In the above configuration, in the case of front obliquely downward blowing, the air blown upward from the air blowing port 16a once hits the up / down air direction changing blade 13 and the wind above the air blowing portion is the angle of the up / down air direction changing blade 13 The bottom surface 16b of the blower port portion 16 is disposed above the lowermost portion of the blowout grill 12 and the bottom surface 16b of the blower port portion 16 is blown obliquely downward. The front edge and the lowermost part of the blowing grill 12 are connected by an inclined surface 18.
[0022]
With this configuration, the wind blown upward from the front blower port 16a is changed downward by the downward wind from the upper part, and drawn toward the inclined surface by the Coanda effect, and blown downward along the surface. Effectively, the wind can be blown to low places where moisture easily collects, such as shoes and laundry placed on the floor surface in front of the air conditioner, and the lower part of the closet and a clog box.
[0023]
(Embodiment 3)
FIG. 5 is a longitudinal sectional view of the blower port portion 16, in which the vertical beam 12 b at the center of the blow grill 12 is connected to the uppermost portion 12 d and the lowermost portion 12 c of the horizontal beam 12 a of the blow grill and the bottom surface 16 b of the blower port portion 16. A substantially triangular shape to be connected is formed.
[0024]
In the above configuration, in the case of forward blowing or forward diagonally downward blowing, the direction of the wind tends to shift to the left from the front due to the centrifugal fan characteristics, but the wind that hits the substantially triangular vertical rib 12b blows forward. The wind that does not come in contact with the component to be discharged is blown forward because the lee of the vertical rib 12b becomes negative pressure.
[0025]
As a result, the wind direction blows almost straight to the main body, so shoes and laundry placed on the floor in front of the air conditioner effectively without changing the direction of the main body due to the deviation of the wind direction. In addition, it can be sprayed to low places where moisture accumulates, such as the lower part of a closet or a clog box.
[0026]
【The invention's effect】
As is apparent from the above description, the invention described in claim 1 is provided with a blow-out grill having a horizontal rail on the front surface of the concave blower opening portion formed in the top surface portion of the outer box constituting the outer shell of the main body. In addition, a plate-like up / down airflow direction changing blade having a shaft portion on the left and right is disposed above the air blowing port portion, and the front end of the up / down airflow direction changing blade is By adopting a configuration in which the upper part of the blowing grille is closed and positioned above the blowing grille, the blowing direction can be continuously changed from the upper side to the front diagonally lower side, so that it can be blown onto the laundry at various positions. Can reduce the drying time.
[0027]
Further, as in the second aspect of the invention, the bottom surface of the blower port portion is disposed above the lowermost portion of the blowout grill, and the bottom front edge of the blower port portion and the lowermost portion of the blowout grill are connected by an inclined surface. Therefore, in the case of the front obliquely downward blowing, the wind at the upper part of the blower port part is blown downward along the direction of the blades for changing the vertical wind direction, and the wind at the lower part of the blower part is blown downward along the inclined surface. Therefore, there is no lift of the wind direction, and it can be effectively sprayed on shoes and laundry placed on the front floor surface, and in low places where moisture tends to accumulate, such as the bottom of closets and shoe boxes.
[0028]
Further, as in the invention described in claim 3, by making the vertical rail of the blowout grill into a substantially triangular shape, it is possible to prevent the deviation of the wind direction due to the characteristics of the centrifugal fan. Also. The strength of the blowout grill, which is weak in strength, can be increased.
