Abstract

PURPOSE:To eliminate a dripping of water into an air conditioned room, and improve a reliability and a convenience in use by a method wherein a cold air blowing part is composed of a water holding member. CONSTITUTION:A cold air blowing part 4 is comprised of a blowing port 6 opened to a ceiling panel 3, and a plurality of louvers 7 and 7 pivotally and rotatably supported at the blowing port 6. Hot air within an air conditioned room R is sucked from the suction part 5 into a main body 1 of an air conditioner, heat exchanged there and then a cold air is generated. A partial hot moistured air is induced by a cold air blown from the cold air blowing part 4, becomes an inducted air as shown by an arrow in the figure and mixed with the cold air. At such a mixing location as one described above, in particular dew is easily formed at the louvers 7 and 7 in its natural phenomenon. However, since the louvers 7 and 7 are made of moisture holding material, all the dew formed are absorbed and an expansion of dew is restricted. Naturally, it is possible to prevent the dew from dripping into the air conditioned room R and then uncomfortable feeling can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to, for example, a ceiling-embedded air conditioner, and particularly relates to an improvement in a structure for preventing dripping of condensation in a cold air outlet.

(Prior Art) For example, a ceiling-embedded air conditioner is configured as shown in FIG. An air conditioner main body 1 that accommodates a refrigeration cycle device (not shown), a blower, etc., is suspended and fixed to a member (not shown) constituting the attic space through a plurality of hanging bolts 2 .

A ceiling panel 3 having a larger area than the main body 1 is integrally provided on the lower surface side of the air conditioner main body 1, and is exposed to the air-conditioned room R through a mounting opening opening in the ceiling (not shown). Further, a cold air blowing section 4 is provided on one side of the ceiling panel 3, and a suction section 5 is provided on the other side, each facing the air-conditioned room R.

The cold air blowing section 4 includes an air outlet and a plurality of louvers provided at the air outlet. The suction section 5 includes a suction port and a filter that detachably closes the suction port.

By driving the refrigeration cycle equipment, blower, etc. in the air conditioner main body 1, warm air in the air conditioned room R is sucked into the air conditioner main body 1 from the suction part 5, thereby exchanging heat. cold air is generated. This cold air is blown out again as cold air into the air-conditioned room along the louvers of the cold air blowing section 4, thereby achieving this cooling effect.

(Problem to be Solved by the Invention) By the way, the temperature of the cold air generated in the air conditioner main body 1 is about 10°C, and the area around the outlet and the louver, which is the cold air blowing part 4, is cooled by the cold air, and the cold air is cooled by the cold air. Almost the same as the blowing temperature
temperature decreases. The air-conditioned room R is cooled and dehumidified by the cold air blown out, and the temperature becomes, for example, about 25 to 27°C. The cold air falls to the lower part of the air-conditioned room R, and warm air rises instead and is sucked into the suction part 5. On the other hand, outdoor air often enters the air-conditioned room R due to opening and closing of the door. Particularly in the summer when cooling operation is performed, Japan is characterized by not only high lu but also high humidity, and the outside air that enters rises near the ceiling panel B and is sucked in through the suction section 5. Alternatively, the high-temperature and humid air in the air-conditioned room R that is not subjected to heat exchange rises. A part of the high temperature and humid air is attracted by the cold air blown from the cold air blowing section 4, and becomes attracted air and mixes with the cold air. If there are fewer hot and humid air vents,
Even with such mixing, the change in the hot water temperature and humidity of the cold air itself is very small, and the influence on the cooling effect is relatively small.

However, it is an unavoidable fact that condensation naturally occurs in areas where cold air and hot, humid air mix. In this case, the cold air blowing section 4
Condensation tends to form around the air outlet and the louvers that make up the unit.

Then, as time passes, the dew grows, and when it exceeds the limit of adhesion and retention, it drips into the air-conditioned room R. People who are exposed to such dew will feel extremely uncomfortable, and if it occurs at a business store, it will give the store a negative image.

Therefore, conventionally, as a means to prevent condensation, flocking has been applied to the area around the air outlet and the surface of the louver constituting the cold air blowing section 4. Specifically, after spraying adhesive onto these objects, piles are planted and dried for a predetermined period of time.

By performing the flocking process in this manner, the desired dew condensation prevention effect can be obtained. However, the flocking process is extremely troublesome and time-consuming, which has a negative impact on cost. In addition, flocked hair is susceptible to changes over time, such as discoloration, lumps, and stains due to dirt, etc.
It has problems such as being easily scratched and difficult to handle.

The present invention has been made in view of the above circumstances, and its purpose is to reduce the growth of dew condensation caused by the mixing of the cold air blown out from the cold air outlet and the warm air attracted there. It is an object of the present invention to provide an air conditioner that prevents dripping into an air-conditioned room and improves reliability and usability.

Another object of the present invention is to provide an air conditioner that can be easily treated to prevent condensation from dripping without any troublesome effort, and that does not change over time.

[Structure of the invention]

(Means for Solving the Problems) That is, the present invention includes an air conditioner main body that takes in air from a conditioned room, exchanges heat with it, and obtains generated cold air, and a cold air blowing section that blows the cold air back into the conditioned room as cold air. The cold air blowing section is constructed of a water retaining member so as to absorb condensation generated when the cold air blown from the cold air blowing section and the warm induced air in the air-conditioned room attracted by the cold air are mixed with each other to prevent dripping. This is an air conditioner with special features.

Further, the present invention includes an air conditioner main body that sucks in air in an air-conditioned room, exchanges heat with it, and blows the generated cold air back into the air-conditioned room from a cold air blowing section, and the cold air blowing out from the cold air blowing section and the generated cold air are cooled. An air conditioner characterized in that a water retaining member that absorbs the condensation and prevents it from dripping is installed at a position where condensation occurs when the warm induced air of the air-conditioned room that is attracted to the cold air blowing part by the cold air mixes with each other and forms condensation. It is a machine.

(Function) By configuring in this way, even if the cold air blown from the cold air blowing part and the warm induced air in the air-conditioned room attracted by the cold air blowing part mix with each other and condensation occurs, this condensation can be prevented. The water retaining member absorbs water and prevents it from dripping into the air-conditioned room.

(Embodiment) An embodiment of the present invention will be explained below by applying it to, for example, a ceiling-embedded air conditioner.Since its basic configuration is as explained above with reference to Fig. 1, this figure will be applied. Further explanation will be omitted. As shown in FIG.
It consists of a plurality of louvers 7.7 rotatably supported on the louvers 7.7.

The members constituting the ceiling panel 3 through which the air outlet 6 opens are made of a synthetic resin material or a metal material with a beautiful surface treatment. On the other hand, the louver 7°7 is made of a water retaining member. Such a water retaining member is composed of a molded plate material that has water retaining properties using foam, for example. This is formed into a louver 7 as it is, and is rotatably supported on the air outlet 6.

By driving the refrigeration cycle equipment, blower, etc. in the air conditioner main body 1, the warm air in the air conditioned room R is sucked into the air conditioner main body 1 from the suction part 5, where heat is exchanged. cold air is generated. This cold air is again blown out from the air outlet 6 of the cold air blowing section 4 along the louvers 7.7 into the air-conditioned room R, as shown by the white arrow in the figure, to perform a cooling effect. Instead, the warm air in the air-conditioned room R rises, is sucked in from the suction part 5, and circulates as described above.

On the other hand, for example, when the door is opened, hot and humid air from outside enters the air-conditioned room R, or hot and humid air from the air-conditioned room R that is not subjected to heat exchange rises and is sucked into the suction section 5. A part of the high temperature and humid air is attracted by the cold air blown out from the cold air blowing section 4, and becomes attracted air as shown by the arrow in the figure, and mixes with the cold air.

Condensation naturally tends to occur at such a mixing site, especially at the louver 7. However, since the louver 7.7 is made of a water retaining member, it absorbs all the generated dew and suppresses the expansion of the dew. Naturally, dew can be prevented from dripping into the air-conditioned room R, and unpleasant feelings will not be caused. The water retaining member itself does not change over time, maintains its beauty over a long period of time, increases commercial value, and does not require any particular troublesome effort in manufacturing the louver 7.

In the above embodiment, the louver 7 is entirely made of a water retaining member, but the invention is not limited to this. As shown in FIG. 3(A), the louver main body 7a may be made of a somewhat thin metal material. , and one side of the louver 7A may be covered with a water retaining member 7b.As shown in FIG. The louver 7B coated with 7d may also be used.

The present invention may also be implemented as shown in FIGS. 4 and 5. That is, the water retaining member 8,
Install 9. The water retaining members 8 and 9 are, for example, multi-foam molded sheets, and are attached to the ceiling panel 3 by integral molding, heat welding, or adhesive, and in any case, they require less effort than conventional flocking. It does not stain and does not change over time.

Therefore, as shown by the white arrow in the figure, some hot and humid air is attracted by the cold air blown out from the air outlet 6 along the direction of the louver 7.7, as shown by the arrow in the figure, and the induced air and mixes with the cold air.

Condensation naturally occurs around the air outlet 6, which is the mixing area, but the water retaining member 8.9 attached here
absorbs all the condensation that occurs and suppresses its expansion. Therefore, it is possible to prevent dew from dripping into the air-conditioned room R.
It is the same as in the above embodiment that the user does not feel uncomfortable. At the same time, there is no problem even if a water retaining member is attached to the louver 7.7 as in the above embodiment.

〔Effect of the invention〕

As explained above, according to the present invention, the cold air blowing section is configured with a holding member that prevents the growth of condensation caused by the mixing of the cold air blown out from the cold air blowing section and the warm air attracted here. Therefore, dripping into the air-conditioned room is eliminated and unpleasant feelings are avoided, and reliability and usability are improved.

Further, in the present invention, the water retaining member is attached at a position where the cold air blown out from the cold air blowing part and the warm induced air in the air-conditioned room attracted to the cold air blowing part mix with each other and condensation occurs. It absorbs water and eliminates dripping into the air-conditioned room, and unlike hair transplantation, it does not require any trouble and does not have a negative impact on cost, and it does not change over time and maintains its beauty, improving product value. It has effects such as obtaining.
