[0005]

However, the above-mentioned ceiling-embedded air cleaner still has the following problems to be solved.

That is, as described above, since the panel is made of resin, it is easily charged with static electricity, and the static electricity adsorbs dust in the room to stain the panel surface.
In particular, the area around the air intake was heavily polluted during operation because dirty air continuously passes through.

Further, as described above, since the wind from the air discharge port is directed to the outer oblique direction and further to the horizontal direction along the ceiling surface as much as possible, part of the air is a ceiling of the panel. The exposed surface flows so as to lick, and a part of the air therein flows along the ceiling surface near the panel.

Therefore, even if the discharged air is clean,
There is also a problem that a swirl is generated due to the flow of the discharged air, and dirty air accumulated in the upper part of the room is entrained and adhered to the ceiling surface to stain the ceiling surface.

In particular, in recent years, the air conditioning in the room has been vigorous, and since it is often cooled in the summer, the air discharged from the air purifier is also cold air, and when such cold air flows along the ceiling surface, However, dew condensation may occur on the cooled ceiling surface, and when the dew condensation occurs, the dust in the room adheres to the ceiling surface, and the ceiling surface becomes more and more dirty.

An object of the present invention is to provide a ceiling-embedded air conditioner capable of solving the above-mentioned problems.

[0011]

In order to solve the above-mentioned problems, the present invention forms an air intake port and an air discharge port, which communicate with the inside of the functional unit casing, which is buried in the ceiling, at the lower end thereof. The panels were connected in series, and at least a part of the exposed portion of the panel on the ceiling surface was formed of an antistatic resin.

Further, according to the present invention, a panel having an air inlet and an air outlet communicating with the inside of the casing is continuously provided at the lower end of the functional casing embedded in the ceiling, and the air outlet is connected to the panel. On the upstream side in the vicinity, a rectifying protrusion is provided so as to prevent the discharged air from flowing toward the ceiling surface side.

Further, according to the present invention, a panel having an air inlet and an air outlet communicating with the inside of the casing is connected to the lower end of the functional casing embedded in the ceiling, and the air inlet is provided. A lid body made of an antistatic resin is attached to be openable and closable, and a rectifying projection for preventing discharged air from going to the ceiling side is provided on the upstream side in the vicinity of the air discharge port.

Then, the above-mentioned rectifying projection is provided so as to project from a round portion of the side wall surface of the panel forming the end portion of the discharge flow path communicating with the air discharge port and the inside of the functional portion casing, and the discharge air comes into contact with the ceiling surface. It prevents it from flowing in the state.

Another feature is that the air purifying unit is housed in the functional portion casing to function as an air purifier.

BEST MODE FOR CARRYING OUT THE INVENTION A ceiling-embedded air conditioner according to the present invention includes a functional portion casing embedded in the ceiling, an air inlet connected to a lower end of the casing and communicating with the inside of the casing. An air discharge port is formed, and the panel has a rectangular shape and is attached to the ceiling surface in an exposed state.

An air purifying unit is housed in the functional portion casing, and it functions as a ceiling-embedded air purifier.

In the above structure, at least a part of the portion exposed on the ceiling surface of the panel is formed of antistatic resin.

That is, specifically, the lid which is openably and closably attached to the air intake provided on the panel is formed of an antistatic resin.

A large number of slits for air circulation are formed on the lid body over substantially the entire surface thereof, and during operation, during operation,
Dirty air continuously passes through such slits, but by preventing the generation of static electricity, it is possible to prevent dust and the like from being attracted and adhered by static electricity and soiling around the slits as much as possible. .

Therefore, even though it is an air purifier, the lid exposed on the ceiling surface is not contaminated by the adhesion of dust, and the occupants do not feel uncomfortable.

The air outlet is provided with a wind direction adjusting plate so that the direction of the discharged air can be changed to any direction.

Normally, in order to prevent the wind from hitting the occupants directly, the air is discharged toward the outside with the wind direction substantially horizontal. However, here, the discharge air is provided near the air discharge port and on the upstream side. Is provided with a rectifying protrusion that prevents the head from heading toward the ceiling surface.

The rectifying projections are provided on the rounded portion of the side wall surface of the panel forming the terminal end of the discharge flow path communicating with the air discharge port and the inside of the functional portion casing.

With this structure, a part of the discharged air flows along the round portion of the side wall surface of the panel and is sent in a substantially horizontal direction along the ceiling, but is hindered by the rectifying projections. Contact with the ceiling surface is prevented as much as possible.

Therefore, vortices generated when the discharged air flows along the ceiling surface do not cause dust and the like in the air, which is involved in the dirty air in the room, to adhere to the ceiling surface.

In particular, when the room is cooled in the summer, the discharged air is also cool air, and when such cool air comes into contact with the ceiling surface, it may be cooled to cause dew condensation, and dust inside the room may adhere to such dew condensation. Although the ceiling surface often becomes dirty, the above configuration can prevent dew condensation.
