Description

[Detailed description of the invention] The present invention is a cassette type air conditioner consisting of a main body, a branch duct, and a decorative panel. The present invention relates to a cassette-type air conditioner that completely prevents condensation on partition blades, provides ideal cooling and heating, and is elegant and has a great design effect on the ceiling surface.

Most conventional cassette-type air conditioners, such as ceiling-mounted air conditioners, have separate air outlets and suction ports on the bottom of the machine, which tends to make the whole machine bulky, and the space under the ceiling tends to be large. There are concerns that the design of the ceiling will be significantly degraded and that many parts will be required, making it expensive.In addition, there are concerns that the recently developed cassette in which the air outlet and suction opening can be formed in parallel on the ceiling panel surface. Even in a type air conditioner, because the outlet and inlet are close to each other, the air rotates back at both inlets, causing a so-called short circuit phenomenon, which causes the air to be spread over a long distance. However, if the air outlet and suction port were arranged in parallel in two directions, the wind speed would be slow, making it impossible to achieve a more effective result.

The present invention is an attempt to fundamentally solve the above-mentioned drawbacks, and in a cassette-type air conditioner consisting of a main body 1, a branch duct 2, and a decorative panel 3, both sides of the decorative panel 3 A heat insulating partition blade 4 is installed in the middle to separate the suction port 5 and the blowout port 6, and the suction portion 7 of the branch duct 2 is eccentric to one side, and the blowout portion 8 is placed on the same line.
are arranged and formed in a substantially straight line, and furthermore, the center panel 9, which has a painted surface a on one side and an interior building material surface b on the other side, can be replaced at the center of the decorative panel 3, making it freely convertible. The purpose of this invention is to widely provide a cassette-type air conditioner that is effective and has a good design.

The following is a detailed description of the ceiling-mounted cassette type air conditioner as an embodiment of the present invention. 1 is a body of the air conditioner with a blower F, an electric motor M, a heat exchange coil C, a drain pan D, etc. Various mechanisms are arranged, and below the branch duct 2, the suction part 7 is eccentric to one side, and the outlet part 8 and the inspection port 10 are arranged substantially in series on the same line.

The suction port 5 and the blowout port 6 are formed in openings on both sides of the ceiling panel, that is, the decorative panel 3 on the lower surface of the machine, so as to be separated from each other in parallel in the axial direction by partition blades 4. Note that the partition blade 4 is made of a heat insulating material for the purpose of blocking cold and warm temperatures, but a certain gap is provided in the center, or a goyu packing 4' is provided inside the blade as shown in Figure 6.
Sometimes it is inserted.

In addition, the central panel 9 of the decorative panel 3 has either the front or back side painted with a painted surface a, while the other side is covered with a building material b that is the same as the ceiling building material surface or the interior building material of the wall surface. Therefore, it can be changed or removed at will depending on the ceiling/wall design, season, year, etc.

In the above-mentioned embodiment, a secondary direction blowout type is used, but in some cases, a unidirectional blowout type may be used with the same structure.

As described above, the present invention includes a main body 1, a branch duct 2,
In a cassette-type air conditioner configured with a decorative panel 3, hot air and cold air are separated by separating the inlet 5 and outlet 6, which are integrally formed in the decorative panel 3, into left and right sides with an insulating partition blade 4. Reliably shuts off the
The occurrence of dew condensation on the blade surface and the short circuit phenomenon near the outlet are completely prevented, and the suction part 7 of the branch duct 2 is eccentric to one side, and the outlet part 8 is arranged approximately in series on the same line. Therefore, it not only prevents the aforementioned short circuit, but also has the effect of quickly stopping the wind speed, significantly extending the range of reach, and providing ideal cooling and heating effects.

Moreover, the painted surface a of the central panel 11 and the interior building material surface b
It also has various advantages such as improving the interior design by selectively changing the front and back sides.

It goes without saying that the present invention can be widely used in any type of device, such as a ceiling-mounted type, a wall-mounted type, etc.
