[Structure] A perforated plate 4 having a large number of small holes 5 is attached to a blowout opening of a central cone 3 of an air blowout port provided with multiple cones 2, and an airflow guide plate 10 is provided at a corner of the cone 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air outlet that blows out cool air and warm air in an air conditioner, and can prevent dew condensation on a cone of the air outlet.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, an air outlet has been widely used in which multiple round and square cones having different sizes are provided at the outlet opening to blow out air in four directions.

[0003]

[Problems to be solved by the device]

 When cold air is blown out from the air outlet in all directions, the warm air in the room rises so that warm air in the room is sucked toward the central cone, and the cool air is blown to the side wall of the central cone. And warm air contacted each other, and the temperature difference caused dew condensation on the central cone. The problem to be solved by the present invention is to solve the conventional problem and provide an air outlet capable of suppressing dew condensation.

[0004]

[Means for Solving the Problems]

 The gist of the present invention, which has solved such a problem, is as follows: 1) In the air outlets in which multiple cones having different sizes are provided in the outlet opening and air is blown out to spread air in all directions, the central cone of the air outlet is blown out. The air blowout port is characterized in that a perforated plate is provided to apply the air flow passing through this blowout part to the part to temporarily retain it and discharge it from the small holes on the surface. 2) The cone shape is square and It is located at the air outlet described in 1) above, where an airflow guide plate is provided at the corner.

[0005]

In this invention, when the cool air is sent to the cone in the central portion, the cool air hits the perforated plate and temporarily stays in the space surrounded by the cone and the perforated plate, and the cool air is discharged from the small holes of the perforated plate. The warm indoor air is prevented from coming into contact with the side wall of the cone and the perforated plate, and the cool air does not come into contact with the cone and the perforated plate to prevent a temperature difference that causes dew condensation. . In addition, the air flow guide plate provided at the corner of the square cone guides cool air toward this corner, so that there is no contact with warm air at this corner, and dew condensation also occurs at this corner. Absent.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of a round cone, FIGS. 3 and 4 show a second embodiment in which an air flow guide plate is provided as a square cone, and FIG. 5 shows another third embodiment of a round cone.

FIG. 1 is a vertical sectional view of the first embodiment, FIG. 2 is a bottom view of the first embodiment, FIG. 3 is a bottom view of the second embodiment, FIG. 4 is a sectional view taken along the line AA of FIG. 3, and FIG. It is a longitudinal cross-sectional view of Example 3. In the figure, 1 is an outlet opening, 2 is a cone, 3 is a central cone, 4 is a perforated plate using an aluminum punching plate, 5 is a small hole provided in the perforated plate, 6 is an air outlet body plate, and 7 is An air conditioning duct, 8 is a cone support plate, 9 is a ceiling wall surface, and 10 is an air flow guide plate.

The first embodiment shown in FIGS. 1 and 2 is an example of an air outlet of a round cone, in which a perforated plate 4 having a small hole 5 with a diameter of about 2.5 mm is attached to the peripheral edge of the tip of the central cone 3. There is. In this embodiment, the cool air sent from the air-conditioning duct 7 passes through the inside of the air outlet body plate 6 and is deflected by the cone 2 and the central cone 3 provided at the outlet opening 1 so as to spread in all directions. It The cool air in the central portion of the passage passing through the inside of the central cone 3 temporarily stays in the conical space surrounded by the central cone 3 and the perforated plate 4, and blows out into the room from the small holes 5 of the perforated plate 4. Therefore, even if the warm air in the room rises so as to be attracted to the central portion of the air outlet by the cold air blown out from the cone 2, the warm air is blown out by the perforated plate 4 and the small holes 5 so that the warm air is released. Since it does not come into direct contact with, the condensation does not occur on the central cone 3 and the perforated plate 4.

Embodiment 2 shown in FIGS. 3 and 4 is an example of an air outlet of a square cone, and is an example in which an airflow guide plate 10 is attached to the corner portion of the cone of the second middle cone. In this embodiment, the cold air sent through the air-conditioning duct is deflected by the cone 2 and the central cone 3 and blown out into the room as in the case of the first embodiment. Here, in the case of a square cone, warm air in the room tends to be attracted to the corner portion of the second cone 2, which tends to cause dew condensation. However, since the airflow guide plate 10 is provided here, cool air can flow to this corner portion. Along with this, a cold air layer is formed to prevent warm air from directly contacting this part and prevent condensation from forming.

In Example 3 shown in FIG. 5, the diameter of the perforated plate 5 in Example 1 was made small so as not to close the entire opening of the central cone 3, so that cold air could flow out from the outside of the perforated plate 5. Here is an example. This is an example in which cold air is strongly applied to the inner wall surface of the central cone 3 to more effectively prevent contact with warm air and to reduce dew condensation.

[0011]

[Effect of device]

 As described above, according to the present invention, by providing the perforated plate that temporarily retains the air in the blowout portion of the central cone, it is possible to prevent warm air from being attracted and contacting the negative pressure area of the central cone, The amount of condensation can be reduced.
