[0002]
[Prior art]
FIG. 5 is a sectional view of a main part of the conventional air conditioner indoor unit blowing nozzle structure with the front panel removed, from a front panel (not shown) for sucking room air into the main body 1 of the air conditioner. A fan casing 4 that forms an air passage 3 between the blowout nozzles 2 is provided. 6 is a heat exchanger arranged on the front panel side in the fan casing, 7 is a fan arranged on the blowing nozzle 2 side in the fan fan casing 4, 8 is a left and right vane provided in the blowing nozzle 2, and 9 is The flaps 10 disposed on the entire surfaces of the left and right vanes are dew receiving portions that are located below the heat exchanger 6 and that form the upper surface of the blowout nozzle 2, and are provided with a plurality of standing leg portions 10a and 10b. Yes. Reference numeral 11 denotes a heat insulating material, which is adhered to the inside of the dew receiving part 10 and the entire surface of the standing leg part 10a with an adhesive or the like in order to prevent dew condensation collected on the dew receiving part 10 from inside the upper surface of the blowing nozzle 2.
[0003]
Next, the operation will be described. In FIG. 5, during cooling, air cooled by heat exchange by the heat exchanger 6 by the operation of the fan 7 is cooled by the cold air flowing through the air passage 3 and discharged from the nozzle 1 into the room. At this time, dew water generated by condensation on the surface of the heat exchanger 6 is collected by the dew receiving portion 10.
[0004]
Further, a technique in which a cavity is provided in the nozzle body so that a heat insulating material is not required is disclosed in, for example, Japanese Patent Laid-Open No. 5-306821 shown in FIG. In FIG. 6, reference numeral 1 denotes an exterior case body of an air conditioner, which has a discharge port edge portion 2 that becomes a nozzle thicker than other portions and is hollow.
[0005]
[Problems to be solved by the invention]
Since the blowout nozzle of the conventional air conditioner is configured as described above, a large number of heat insulating materials or the like matching the nozzle shape are attached with an adhesive or the like. Moreover, the adhesive strength of the adhesive was weak and could be peeled off, and there were problems such as large variations in the attaching position during mass production. Another problem is that a link or the like for moving a vane in the air path contributes to a pressure loss or a decrease in the air volume in the air path.
[0006]
In addition, Japanese Patent Laid-Open No. 5-306821 has a problem in that a step of pressurizing and injecting a gas such as nitrogen is added to the formation of the hollow portion, which is not good in terms of work environment and takes time.
[0007]
This invention is made in order to eliminate the above problems, and a first object is to obtain a heat insulating effect after eliminating a heat insulating material to be attached to a dew receiving portion of an air conditioner. .
[0008]
The second object is to obtain a structure that suppresses assembly variations during mass production and does not cause defects.
[0009]
The third object is to secure a high sealing degree of the sealed space of the dew receiving part main body.
[0010]
The fourth object is to fix the structure of the dew receiving part main body at a low cost while maintaining a high sealing degree.
[0011]
The fifth object is to obtain a heat insulating effect while suppressing cost.
[0012]
The sixth object is to reduce the pressure loss of the blowing nozzle.
[0013]
