Description

Dual Discharge Grille and Air Conditioner with the Same, Dual Discharge Grille

The present invention relates to a double discharge grill and an air conditioner having such a double discharge grill, and more particularly, to prevent safety accidents and improve the ventilation ability through a double discharge grill having blades having different numbers from each other.

In general, an air conditioner sucks indoor air and heats it through a heat exchanger to discharge cool air back into the room to cool the room. Most of these air conditioners are formed under the main body to allow indoor air to flow into the interior. An intake port, a filter member that filters the air sucked through the intake port, a blower fan that allows the air passing through the filter member to move upward, a heat exchanger (evaporator) to lower the temperature of the air passing through the blower fan , A discharge grill is provided to discharge the cool air that has passed through the heat exchanger back to the room.

Here, in the related art, the discharge grill has a shape in which a plurality of transverse blades capable of adjusting the angle are provided at intervals from the top to the bottom.

Therefore, when the cold air is discharged, it is discharged through the gap between the plurality of blades, but since it is exposed to the outside, there is a risk of a safety accident due to the inflow of fingers or the like between the plurality of blades, and the gap between the blades to prevent such safety accidents. In the case of narrowing, since the cold air blown by the blowing fan cannot be properly discharged, the blowing capacity is deteriorated, and thus, there is a problem in that the indoor cooling effect is deteriorated.

In addition, in the conventional air conditioner, a safety net to prevent safety accidents and foreign substances from entering the discharge grill may be installed, but there is a problem in that the ventilation capacity is lowered as the safety net is installed.

Hereinafter, specific details for carrying out the present invention will be described in detail based on the accompanying exemplary drawings.

The terms used in the present specification have selected general terms that are currently widely used as possible while considering functions, but this may vary according to the intention or custom of a technician working in the field or the emergence of new technologies. In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning will be described in the description of the corresponding specification. Therefore, it should be noted that terms used in the present specification should be interpreted based on the actual meaning of the term and the entire contents of the present specification, rather than a simple name of the term.

1 is a perspective view of a double discharge grill according to an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a vertical cross-sectional view of FIG. 2.

As shown in FIGS. 1 to 3, the double discharge grill 1 according to an embodiment of the present invention comprises a first grill part 10 and an outer peripheral surface of the first grill part 10 while forming a circular shape as a whole. It consists of a second grill portion 20 formed in.

In addition, a hub part 30 is formed at the center of the first grill part 10.

In addition, a plurality of blades are formed in the first grill portion 10 and the second grill portion 20 along a circumferential direction, and the first grill portion 10 includes a plurality of first blades 12 along the circumferential direction. Is formed, and thus, a plurality of the first blades 12 are formed on the outer circumferential surface of the hub part 30 at intervals.

In addition, the second grill portion 20 also has a structure in which a plurality of second blades 22 are formed on the outer peripheral surface of the first grill portion 10 along the circumferential direction.

In addition, a ring-shaped support tube 14 is formed in a circumferential direction at an end of the first blade 12 of the first grill part 10.

Accordingly, the first blade 12 is fixed to the inner surface of the support pipe 14, and the second blade 22 is fixed to the outer surface of the support pipe 14.

Here, the number of the first blades 12 and the second blades 22 may be different from each other.

More specifically, it has a structure in which the number of second blades 22 is greater than the number of first blades 12 disposed inside the second blade 22.
In addition, as shown in Figs. 1 and 2, of course, when viewed from the front, both the first blade 12 and the second blade 22 are formed in a curved shape and bent in the same direction. .

In other words, since the circumferential length increases from the hub portion 30 to the outer side in the radial direction, when the blade is arranged as a single blade, the distance increases toward the outer side of the blade. Therefore, if the number of blades is formed at intervals in which fingers do not enter, the intervals between the blades are narrowed, so that the discharge of cold air by the blowing fan 110 may be hindered.
