Abstract

PURPOSE:To facilitate the assembly and disassembly of component elements and prevent leakage of heat and air by a method wherein an indoor casing, drip pan, mouth ring, evaporator lid and cold air discharging duct are removably arranged and divided in a vertical direction and formed of synthetic resin. CONSTITUTION:On a base 1 are mounted a drip pan and a casing 13 integrally formed with a lower half mouth ring and a lower half casing by synthetic resin, and then another casing 14 having integrally formed with an upper half mouth ring, upper half casing and evaporator lid in a similar manner as above is assembled on the former casing. A casing 15 integrally formed with synthetic resin is mounted on the casing 14 in such a manner as the inner surface of the cabinet 1 is covered by the upper part of the casing and then screwed to a partition wall 19 with a band 16 by screws 20. The evaporator is held and fixed among the projections 13a to 13c and 14a to 14c. The casings 13 and 14 are abutted to each other with the inverted right and left projections. Thereby, it is possible to improve a sealing characteristic and facilitate the assembly and disassembly of the component elements.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a casing for an air conditioner, and particularly to a casing for an air conditioner, which can securely maintain the position of an indoor ventilation casing, can be assembled and disassembled easily, and can be easily assembled and disassembled. The present invention relates to a casing structure suitable for preventing wind leakage.

[Prior art]

In the conventional air conditioner, as shown in Fig. 1, a decorative cover 17 is installed in front of the cabinet 1.
Base 2 is installed inside. A partition wall 19 is installed on the base 2 to separate the indoors and outdoors.
A dew pan 5 is installed on the indoor side partitioned by 9, and receives condensed water dehumidified by the evaporator 6. Air sucked in by the indoor blower 11 is cooled by the evaporator 6, passes through the mouth ring 7, the casing 4, and between the evaporator lid 6 and the cabinet 1 and is discharged indoors.

Still between the evaporator lid 6 and the evaporator 6 and the cabinet 1
Insulating material 9. A heat insulating material 8 is installed to prevent dew on the upper surface of the evaporator lid and the outer surface of the cabinet 1. In such a structure, the dew pan 5. Mouth ring 7, casing 4. It requires many parts such as the evaporator lid 6, and is difficult to assemble and disassemble. In addition, since there are so many joints between each part, there are many cases in which the air is not completely cooled, so by the time the air cooled by the evaporator 3 is discharged into the room, it is likely to leak, reducing the cooling capacity or leaving the air uncooled. Since hem formation occurs due to air, there are drawbacks such as sealing with various sealing materials.

[Purpose of the invention]

The purpose of the present invention is to improve the above-mentioned drawbacks, reduce the number of parts, and improve the sealing performance between the parts.
Our purpose is to provide casings for 2-air wholesalers.

[Summary of the invention]

That is, the present invention provides that, on the indoor side of an air conditioner consisting of a cabinet 1, a base 2, a decorative cover 6, and a partition wall 19, the lower half of the dew pan, the lower half of the mouth ring, and the lower half of the casing are made of synthetic resin. The upper half of the mouth ring, the upper half of the casing, and the evaporator lid are integrally molded with synthetic resin, and the upper half of the mouth ring is integrally molded with synthetic resin to cover the inner surface of the gear vignette from the upper part of the casing. By combining these, the above objectives can be achieved.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 2 and Fig. 6.

On the base 1, the dew pan, the lower half of the mouth ring, and the lower half of the casing are integrally molded with synthetic resin, and the casing A, 16 is installed. It is a combination of Ken-ung B14 whose lid is integrally molded from synthetic resin. Furthermore, a casing C15 integrally molded of synthetic resin is installed on the casing middle B so as to cover the inner surface of the cabinet 1 from the upper part of the casing, and is fixed to the partition wall 19 by a fixing band 16 with screws 20. Casing A13 and casing B
A sirocco fan 11 is installed inside the fan 14 to form a ventilation path for cooling air. Also, the evaporator 6 is Goosong A13
Protrusions 13a, 13b, 13c provided on the parts and protrusions 14a, 14b, 14c provided on the casing B14.
Fix the scissors in between. As shown in FIG. 6, the mating portion of the casing A 13 and the casing middle 14 is provided with protrusions 13d and 14d that are opposite in left and right directions in accordance with the air flow direction 21 to prevent leakage of cooling air.

The air sucked in through the decorative cover 17 is cooled by the evaporator 6, passes through the mouth ring portions of the casings A and 16 and the casing B 14, is pushed out by the blower 11, and is drawn into a duct made up of the casings B 14 and casing C15. It passes through and is discharged into the room.

The present invention is constructed like a double chain, and can be easily attached and detached in the vertical direction by removing only the fixing band 16. Still casing A16. Casing B14. By providing the protrusion of the mating part of the casing C15 to match the flow of cooling air, the sealing performance is the same as above, and there are effects such as being able to provide an air conditioner with a structure that reduces the reduction in cooling capacity and reduces condensation. .

〔Effect of the invention〕

According to the present invention, the number of parts is reduced due to the integration of synthetic resin, and the sealing performance between parts is improved, which prevents the cooling capacity from increasing. It provides a casing with a Chofu 0-iso.
