Abstract

(57) [Summary] [Purpose] Providing an air-conditioning blowout louver that does not cause condensation and does not get wet or dirty due to condensation. [Structure] A large opening 4 communicating with a duct 3 is provided at one end of a spherical shell 1 rotatably supported, and a blowing nozzle projecting in a cylindrical shape at a portion of the spherical shell 1 on the opposite side of the opening 4. A portion 5 is provided, and the opening 4 of the spherical shell 1 and the blow-out nozzle portion 5 are connected by a flanged heat-insulating cylinder 6 to form a blow-out passage 9 in the heat-insulating cylinder 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a punk louver for an air conditioning blowout device that freely blows conditioned air in a desired direction.

[0002]

[Prior art]

 The conventional bunker bar has a large opening that communicates with the air duct at one end of an aluminum spherical shell that is rotatably supported, and has a cylindrical projection on the opposite side of the opening. The blowout nozzle was provided.

[0003]

[Problems to be solved by the device]

 In conventional bunker bars, the spherical shell is made of aluminum, so if the cooled air comes into direct contact with the spherical shell, the temperature difference from room temperature causes condensation on the surface of the spherical shell, which causes the spherical shell to become wet. However, water droplets dripped and polluted the interior of the room and caused mold. The problem to be solved by the present invention is to provide a bunker louver that solves the problems of the conventional bunker lover and does not cause dew condensation.

[0004]

[Means for Solving the Problems]

 The gist of the present invention, which has solved such a problem, is to provide a large opening communicating with a duct at one end of a spherical shell that is rotatably supported, and to project a cylindrical shape at the opposite side of the opening to the spherical shell. In a bunker bar provided with such a blowout nozzle portion, a blower passage is formed by connecting the opening of the spherical shell and the blowout nozzle portion with a flanged heat insulating cylinder to form a blowout passage in the heat insulating cylinder. Located on the louver.

[0005]

[Action]

 In this device, the cooled air sent from the duct flows in through the opening of the spherical shell, passes through the blowout passage of the heat insulating cylinder, and is blown out into the room through the tip opening of the blowout nozzle. The airflow in the punk louver only passes through the heat insulating cylinder, it does not come into direct contact with the spherical shell, and the air in the space between the heat insulating cylinder and the spherical shell also transfers heat by the heat insulation by the heat insulating cylinder. It is not cooled down by condensation, and no condensation occurs on the surface of this space and the spherical shell.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of the embodiment, in which 1 is a spherical shell made of aluminum, 2 is a spherical seat for rotatably supporting the spherical shell 1, 3 is a duct, and 4 is a spherical shell. 1 is an opening portion, 5 is a blow-out nozzle portion projecting in a tubular shape, 6 is a heat insulating tubular body made of foamed resin, 7 is a chamber wall, 8 is a mounting bracket for attaching the spherical seat 2 to the chamber wall 7, and 9 is a blow passage. Reference numeral 10 denotes a collar portion of the heat insulating cylinder 6.

In this embodiment, cooling air sent through the duct 3 enters through the opening 4 of the pan curl bar of this embodiment, and then passes through the blow-out passage 9 inside the flanged heat insulating cylinder 6 as it is. It blows out into the room from the blowing nozzle part 5. The blowing direction from the blowing nozzle portion 5 can be arbitrarily adjusted by freely moving the spherical shell 1 with respect to the spherical seat 2. In this way, the cooling air in the duct 3 is not directly contacted with the spherical shell 1 but is thermally insulated by the heat-insulating cylinder 6, so that dew condensation does not occur near the blowout of the bunker bar.

[0008]

[Effect of device]

 As described above, according to the present invention, the flanged heat-insulating cylinder is provided inside the bunker bar and blows out without direct contact with the spherical shell, which prevents condensation on the surface of the spherical shell. We were able to reduce the generation of water, dirt, and mold due to condensation.

Claims (1)

[Scope of utility model registration request] 1. A large opening communicating with a duct is provided at one end of a spherical shell rotatably supported, and a blow-out nozzle portion projecting in a cylindrical shape is provided at a spherical shell part opposite to the opening. In the bunker louver, the bulging passage is formed in the heat insulating cylinder by connecting the opening of the spherical shell and the blowout nozzle by a heat insulating cylinder with a collar.
