Abstract

PURPOSE:To abolish implantation of a wind direction altering blade and to realize a large cost reduction by preventing condensation to the blade. CONSTITUTION:A step for throttling a diffuser is provided at both ends 4 of a diffusing port of an indoor side ventilating circuit to raise a wind speed. A straightening plate 3 is provided at a step 2 of the diffuser to eliminate disorder of wind. A structure for extending a diffuser end face 4 is formed to obviate the disorder of the wind even when a wind direction is altered to right or left side.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art An indoor unit of a conventional air conditioner will be described with reference to the drawings.

FIG. 2 is a perspective view of an air outlet of an indoor unit of an air conditioner, and FIG. 6 is an enlarged perspective view of an air outlet of an indoor unit of an air conditioner showing a conventional example in which the portion B of FIG. 2 is enlarged. is there. In the indoor unit of the conventional air conditioner, the dew condensation water on the wind direction changing blade 1 during cooling is replenished to prevent dripping by planting hair on the air direction changing blade 1.

[0004]

However, when the wind direction changing blades are transplanted as described above, the cost is very high, and when the machine is operated for a long time, the dew condensation water cannot be retained and drops. It was The present invention solves the above conventional problems.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a step at both ends of an indoor ventilation circuit for squeezing the outlet, and a rectifying plate at the step of the outlet. Moreover, it is configured such that the end face of the outlet is widened.

[0006]

According to the present invention, the wind speed is increased by providing steps at both ends of the indoor ventilation circuit so that the air outlets are narrowed, and a rectifying plate is provided at the step portions of the air outlets to eliminate turbulence of the wind. With the structure in which the end face of the outlet is widened, the turbulence of the wind can be eliminated even when the wind direction is changed from side to side, and dew condensation on the airflow direction changing blade during cooling can be prevented.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An indoor unit of an air conditioner according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an indoor unit of an air conditioner according to an embodiment of the present invention. 2 is an enlarged view of a portion A of FIG. 1, and FIGS. 3, 4, and 5 are enlarged views of a portion B of FIG. In FIG. 3, the wind speed is increased by providing a step 2 that narrows the air outlet on both ends of the air outlet of the indoor side ventilation circuit, and further by providing a rectifying plate 3 on the step 2 of the air outlet as shown in FIG. Eliminates turbulence in the wind and prevents condensation on the airflow direction changing blades during cooling. Further, as shown in FIG. 5, the structure in which the end face 4 of the outlet is widened eliminates the turbulence of the wind even when the wind direction is changed to the left and right, and prevents dew condensation on the airflow direction changing blade during cooling.

[0009]

As is apparent from the above description, the present invention has the following advantages.
By providing a step at both ends of the indoor ventilation circuit that narrows the outlet, the wind speed is increased, and a rectifying plate is provided at the step of the outlet to eliminate turbulence and widen the end face of the outlet. With the structure, even when the wind direction is changed to the left or right, the turbulence of the wind can be eliminated, and dew condensation on the airflow direction changing blade during cooling can be prevented. Further, by preventing the dew condensation on the wind direction changing blade, it is possible to eliminate the flocking of the wind direction changing blade, and it is possible to significantly reduce the cost.
