JPH0648108B2 - Blow-out device of ceiling-embedded air conditioner - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a blowing device for a ceiling-embedded air conditioner.

2. Description of the Related Art In recent years, an air conditioner used by being embedded in a ceiling, a wall or the like has been increasing in terms of space saving and interior property.

Hereinafter, an example of the structure of the air outlet of the conventional ceiling-embedded air conditioner will be described with reference to the drawings.

FIG. 2 is a perspective view of a decorative panel installed on the ceiling, where 1 is a suction port, 2 is a blowout port, 3 is a vertical change blade, and 4 is a horizontal change blade. FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, and 5 is a connecting machine, which is made into a block by connecting several right and left changing blades 4, and the direction can be changed left and right for each block. There is.

With respect to the above-described configuration, the operation is such that the air in the room is first sucked in through the suction port 1, heat exchange is performed by the known refrigeration cycle, and cold / warm air is blown out through the blowout port 2.
The direction of the blown wind can be changed according to the preference of the user by the vertical change blade 3 in the vertical direction and the horizontal change blade 4 in the horizontal direction.

Problems to be Solved by the Invention However, in the above-mentioned configuration, when the cool air is blown out, when the left / right change vane 4 is directed to the left / right as shown by the broken line in FIG. Change feather 4
At the side of the, wind turbulence occurs as shown in FIG. Since the turbulence of the wind is a mixture of the cold air blown out and the room air, the left and right changing blades 4 are condensed in the vicinity of the turbulence. This dew condensation increases with time, and eventually there is a problem that it drops and wets the floor surface.

The present invention has been made in view of the above problems, and an object of the present invention is to prevent dew condensation on left and right changing blades.

Means for Solving the Problems In order to solve the above problems, the blowout device of the ceiling-embedded air conditioner of the present invention has a plurality of left and right changing vanes, which are connected to each other by a connecting machine to form a block. A straightening vane is provided between one block of the left / right change vane and the other block, and has two protrusions having a triangular cross-section with the upwind side and the downwind side as vertices.

Operation According to the present invention, due to the above configuration, even when the respective blocks of the left and right change vanes are oriented in the opening direction during cooling, the turbulence of the wind in the portion formed in the shape of a figure is eliminated, and as a result, the left and right change vanes are changed. Condensation of can be prevented.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an enlarged cross-sectional view of an outlet of a ceiling-embedded air conditioner in this embodiment. Reference numeral 11 is a left / right change vane, 12 is a connecting device, 13 is a straightening plate, and triangular prism-shaped projections 13a and 13b are provided in a triangular cross-section having vertices on the windward side and the leeward side in a direction perpendicular to the wind flow. There is.

In the above-described configuration, during the cooling operation, the cold air flowing from the windward side is bent left and right by the protrusion 13a of the straightening vane 13, and due to the effect, the wind is blown even on the side surfaces of the left and right changing blades 11 opened in an eight shape. Since it flows smoothly along the left and right changing blades 11 without being disturbed, dew condensation on the side surface does not occur. In addition, the leeward protrusion 13b is the leeward protrusion 13b.
This is for smoothing the flow of the turbulence just below a to re-rectify it smoothly, and by these two projections 13a and 13b, the dew condensation near the outlet is eliminated, and it is indispensable to drip to wet the floor surface. Disappear.

In this embodiment, two projections having a triangular cross section are combined, but the same effect can be obtained even if the projection has a rhombic cross section.

EFFECTS OF THE INVENTION As described above, according to the present invention, the left and right changing blades are divided into blocks by a connecting machine, and one side of the blocked left and right changing blades and the other are the leeward and leeward apexes. By providing the rectifying plate having the two protrusions having a triangular cross section, there is no need for dew condensation or dripping, and there is an effect that the wind direction can be freely changed according to the preference of the user.
