Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device provided at the wind outlet of an air conditioner.

[Conventional technology]

3 to 5 are diagrams showing a conventional air conditioner outlet device disclosed in, for example, Japanese Utility Model Application No. 58-69735, and FIG. 3 is a perspective view of the air conditioner main body, and FIG. The figure is a cross-sectional view taken along the line -- in FIG. 3, and FIG. 5 is a cross-sectional view taken along the line -- in FIG.

In the figure, 1 is the main body of the air conditioner, 2 is a front panel that covers the front of the main body 1 and has a suction port 3, 4 is an air outlet that opens at the lower front of the main body 1, and 5 is arranged facing the suction port 3. 6 is a casing provided in the main body 1 and forms an air passage 7; 8 is a blower installed on the side of the air outlet 4 of the air passage 7 and driven by an electric motor 9;
10 is a blowout nozzle arranged below the casing 6 and forms an air passage together with the casing 6; 11 is a plurality of blowout nozzles arranged in parallel between the left and right side walls 12 and 13 of the blowout nozzle 10, and is supported by a pivot 14 to convert the wind direction from side to side. A guide vane 15 is provided at the air outlet 4 and is pivotally connected to the left and right side walls 17 and 18 of the front panel 2 by a shaft 16 attached to the left and right ends, and is a change vane that converts the wind direction into horizontal, vertical and diagonal directions. 19 is axis 1
It is a coil spring that is locked to 6.

The outlet device of a conventional air conditioner is configured as described above, and when the blower 8 is driven during cooling, room air is sucked in from the suction port 3, passes through the heat exchanger 5, is cooled, and then The air flows down the path 7 and is blown out from the air outlet 4 into the room. This wind flow is indicated by arrow A. The left and right direction of this wind is determined by guide vane 1.
1, the vertical direction is adjusted by a change vane 15. FIG. 5 shows a state in which the guide vane 11 is adjusted so that the wind blows out at the center.

[Problem that the invention attempts to solve]

In the conventional air conditioner outlet device as described above, for example, if the direction of the guide vane 11 is set so that the wind blows out to the center, the leftmost air is blown out toward the center by the guide vane 11. Therefore, the air pressure near the left side wall 17 becomes negative pressure. Therefore, the air containing moisture near the front left end B of the front panel 2 is sucked in as shown by the arrow C.
The air enters the inside along the left side wall 17 and is blown out to the center by the guide vane 11 at the left end. In this way, when warm indoor air containing moisture comes into contact with the already cooled left side wall 17, it is cooled below the dew point and condenses, and if this continues for a long time, it becomes water droplets and drips. There is. Also,
These dews adhere to the front decorative part of the front panel 2, so as a countermeasure, attaching heat insulating material, etc.
There is also the problem that it seriously damages the appearance.

This invention was made to solve the above problems, and aims to provide an air conditioner outlet device that eliminates water droplets from dripping from the outlet and does not impair its appearance. purpose.

[Means for solving problems]

The outlet device for an air conditioner according to this invention is provided with a guide wall at a predetermined distance from the side wall of the outlet nozzle for guiding the blown air to the side wall of the outlet.

[Effect]

In this invention, since the guide wall is provided near the side wall of the blow-off nozzle, the air blown from the side of the blow-off nozzle is blown out along the side wall surface of the blow-off port. Therefore, air is no longer sucked in from the front along the side wall surface.

〔Example〕

1, 3, and 4 are views showing one embodiment of this invention, and FIG. 1 is a cross-sectional view of the main part corresponding to FIG. 5, and 1 to 19 are similar to the conventional device described above. belongs to.

In the figure, 21 is formed in a dogleg shape and the guide vane 1
1 and the left side wall 1 of the blowout nozzle 10
2, and is fixed to the blow-off nozzle 10 at an interval of about 20 mm from the left side wall 12, and is similarly provided on the right side.

In the air conditioner outlet device configured as described above, if the guide vane 11 is set to face right as shown in FIG. 1, the direction of the cold air is converted to the right by the guide vane 11. However, the direction of the cold air at the left end is changed to the left by the guide wall 21, and is blown out against the left side wall 17 of the front panel 2, as shown by arrow _A1 . Therefore, the air near the front left end B of the front panel 2 is not sucked along the left side wall 17, so dew does not adhere to the left side wall 17 surface, and water droplets are prevented from dripping.

FIG. 2 is a cross-sectional view of a main part similar to FIG. 1 showing another embodiment of this invention, in which a flat guide wall 22 is moved from near the pivot axis 14 of the leftmost guide vane 11 to the left side wall 17 side. It is installed at an angle, and there is also a similar one on the right side. This example is also the first
The same effect as in the figure can be obtained.

[Effect of idea]

As explained above, in this invention, a guide wall is provided at a predetermined distance from the side wall of the blow-off nozzle to guide the blow-off air to the side wall of the blow-off port. This eliminates the suction of air along this area, which has the effect of preventing water droplets from dripping due to dew adhering to this area. Further, there is also the effect that the appearance is not impaired in any way and the need for adhesion of heat insulating material is eliminated.
