Abstract

PURPOSE:To prevent dews from adhering to the vicinities of an air flow direction control plate and an air exhaust port by disposing other air flow direction plate on the lee side than a load space created by the change in the air flow direction by means of an air flow directing plate. CONSTITUTION:When an air flow directing plate 2 inclines toward a direction in which blast air flows, the blast air which has passed a heat exchanger 5 and has been cooled is divided into the right hand and the left hand at a part (a) of the air flow directing plate 2, and the blast air divided into the right hand is separated at a part (b) and the blast air divided into the left hand is separated at the part (a), and they are converged at a part (c). Since the air flow directing plate 2 is located on the lee side than the part (c), the blast air which has passed the heat exchanger and has been cooled is sucked into a space (d) having a pressure lower than that of the circumference. Hence, no indoor ambient air is sucked up, and air passing the air flow directing plate 3 is only cooled blast air, and almost no dews adhere to the air flow directing plate 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a wind direction control device for an air conditioner.

[Background of the invention]

Conventionally, in a wind direction control device for an air conditioner that has two types of wind direction plates at the air outlet, the wind direction plate located upwind with respect to the flow direction of the blown air is tilted with respect to the flow direction of the blown air of the wind direction plate population. There was a drawback that dew easily formed on the wind direction plate on the leeward side and around the air outlet, and dew easily dripped onto the indoor floor especially when the humidity was high.

The above phenomenon will be explained with reference to FIGS. 6 to 8. 1
Reference numeral 1 denotes an in-mold unit of an air conditioner, 12 a wind direction plate for controlling the left and right wind directions, and 13 a wind direction plate 13 for controlling the upper and lower wind directions, which is located downwind from the wind direction plate 12 with respect to the flow direction of the blown air. The wind direction plate 15 indicates a heat exchanger. When the wind direction board 12 is tilted with respect to the flow direction of the blown air of the wind direction board 12 as shown in FIG. Wind direction If in part a
The blown air separated from i12 and diverted to the right separates from the wind direction plate 12 at part b and joins again at part 0.

The pressure in the space d between this is lower than the surrounding pressure, so the 8th
As shown in the figure (uncooled indoor air is sucked into the space d, the airflow direction plate 13 located downstream from the airflow direction plate 12 with respect to the flow direction of the air flow is filled with the cooled air that has passed through the heat exchanger). Because it comes into contact with uncooled indoor air,
It is easy for dew to form on the wind direction plate 13 (and when the indoor humidity is high, it is easy to drip onto the indoor floor.
No. 136 can be mentioned.

[Purpose of the invention]

An object of the present invention is to reduce the formation of dew on the wind direction control board and around the air outlet even when the wind direction control board is tilted from the blown air of the wind direction control board during cooling operation. An object of the present invention is to provide a wind direction control device.

[Summary of the invention]

The present invention resides in that the wind direction plate on the leeward side is provided downstream of the negative pressure space. As a result, it is possible to prevent uncooled indoor air from coming into contact with the wind direction plate on the leeward side, thereby reducing the amount of condensation on the wind direction plate and around the air outlet.

[Embodiments of the invention]

Embodiments of the invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 is an indoor unit of an air conditioner;
2 is a wind direction plate that controls the left and right wind direction; 3 is a wind direction plate that is located downstream of the wind direction plate 2 with respect to the flow direction of the blown air and controls the vertical wind direction; and 5 is a heat exchanger. In the above configuration, as shown in FIG. 2, when the wind direction plate 2 is tilted with respect to the flow direction of the blown air, the blown air that has passed through the heat exchanger 5 and is cooled is transferred to three parts of the wind direction plate 2. The blown air separated to the left and right is separated at 5 parts, and the blown air separated to the left is separated at 3 parts and joins at 0 parts. Since the wind direction plate 3 is located downstream of the 0 part, only the cooled blast air that has passed through the heat exchanger is sucked into the space d, which has a lower pressure than the surrounding area, and the indoor ambient air is not absorbed as in the conventional case. Since the air that passes through the wind direction plate 3 is only cooled blown air, there is an effect that there is less dew on the wind direction plate 3. It has been experimentally confirmed that the effect is large when the distance is three times or more.In the above embodiments, the distance between the wind direction plate 2 and the wind direction plate 3 has been explained, or the distance between the wind direction plate 2 and the wind direction plate 3 in FIG. It goes without saying that the position of the rotating shaft and the blade portion may be shifted, as in the case of the wind direction plate 3 in FIG. 5.

〔Effect of the invention〕

As described in detail above, according to the present invention, the distance between the blades of the wind direction plate 2 and the wind direction plate 3 has the effect of reducing the amount of equipment around the wind direction plate and the air outlet.
