The present invention relates to an air conditioner, and more particularly to a fastening structure of an air conditioner panel.

In general, the air conditioner is a device that has a function of heating, cooling, humidity, air filtration, air volume control, humidification, etc. of the air, is a device that sucks the air to convert the air into comfortable air.

Such air conditioners are classified into general air conditioners and clean room air conditioners according to indoor cleanliness. Especially in the case of clean room air conditioners, the airtightness should be kept completely confidential.

In any case, the air conditioner is of good quality for the air supplied to the room to ensure perfect airtightness. Therefore, it is important to ensure no leakage.

1 is a perspective view of an air conditioner. The air conditioner 10 shown in FIG. 1 includes a blower, a cooler, a dehumidifier, and the like, and a plurality of panels 12 are installed around the air conditioner. In addition, the upper portion is provided with a damper 14 so that air can be sucked or discharged, and a viewing window 16 is installed at the side so as to know the internal state.

In particular, the panel 12 is fastened to the frame using a bolt, but the head of the bolt is exposed to the outside as it is. 2 is an exploded view of a conventional bolt fastening structure used in the air conditioner as shown in Figure 1, Figure 3 is an assembly view of the bolt fastening structure shown in FIG. 2 and 3, one side of the frame 20 is provided with a gasket 22 to prevent leakage or leakage. The panel 12 is fastened to the frame 20 by screw bolts 28.

The interior of the panel 12 is filled with an insulator 24 for thermal insulation. The screw bolt 28 has a length equal to or greater than the thickness of the panel 12, and a hexagonal bolt is formed at the head.

A dome washer 30 and a neoplan washer 32 are inserted between the head of the screw bolt 28 and the panel 12. These washers 30 and 32 are effective for increasing the tightening force of the screw bolt 28 and maintaining airtightness.

However, as shown in FIG. 3, the head of the screw bolt 28 and the various washers 30, 32 are exposed to the outside of the panel 12 as it is. As a result, the appearance quality of the air conditioner is lowered, which causes a decrease in customer satisfaction.

Therefore, much research has been conducted on the improvement of the structure which can maintain the airtight while concealing a bolt.

Therefore, the present invention has been devised to solve the above problems, the object of the present invention is to fasten the air conditioner panel so that the head of the bolt is not exposed to the outside while maintaining the air tightness of the air conditioner thoroughly To provide a structure.

An object of the present invention as described above, the screw bolt 48 is fastened to the frame 40 through the panel 46;

A concave washer 52 interposed between the head of the screw bolt 48 and the panel 46 and recessed into the panel 46 to assemble with the head of the screw bolt 48 inserted;

A rubber washer 50 fitted into the screw bolt 48 in the concave washer 52; And

It can be achieved by the fastening structure of the air conditioner panel, characterized in that the cap 56 is fitted to the circumferential region of the concave washer 52 while covering the entire upper surface of the concave washer (52).

And, it is suitable that the O-ring 54 is further inserted between the circumference of the concave washer 52 and the panel 46.

In addition, the gasket 42 is preferably further assembled between the frame 40 and the panel 46.

In addition, the cap 56 includes a locking portion 60 formed along the circumferential direction so as to fit in the circumferential region of the concave washer 52; And

A protrusion 62 inserted into the concave washer 52 and in close contact with an inner wall of the concave washer 52,

Cap 56 is most preferably formed integrally by injection.

Other objects, specific advantages, and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings with respect to the configuration of an embodiment according to the present invention will be described in detail.

Figure 4 is an exploded view of the fastening structure according to the present invention that can be used in the air conditioner as shown in Figure 1, Figure 5 is an assembly view of the fastening structure shown in Figure 4, Figure 6 is a cap shown in Figures 4 and 5 56 is an enlarged view.

4 to 6, one side of the frame 40 is provided with a gasket 42 to prevent leakage or leakage. The panel 46 is fastened to the frame 40 by the screw bolts 48.

The interior of the panel 46 is filled with an insulator 44 for thermal insulation. The screw bolt 48 has a length greater than or equal to the thickness of the panel 46, and a hexagonal bolt is formed at the head.

The recess washer 52 is recessed in the remaining portion except for the circumference, and a through hole is formed in the center thereof. The concave washer 52 is fastened in a manner of entering into the panel 46. And, the circumference of the concave washer 52 is bent so that the O-ring 54 can be fitted.

The rubber washer 52 is a rubber having a sufficient thickness and exhibiting sufficient elastic force for hermetic holding. This rubber washer 52 may be replaced with an O-ring having the same performance.

As shown in FIG. 6, the cap 56 has a locking portion 60 formed therein to be coupled to an upper surface of the concave washer 52, and a protrusion 62 protrudes from the center region. The protrusion 62 enters into the concave washer 52 and is in close contact with the inner wall of the concave washer 52.

The O-ring 54 is sandwiched and fixed between the circumferential region of the concave washer 52 and the panel 46. This O-ring 54 is intended to prevent airtight leakage between the panel 46 and the recess washer 52.

Hereinafter, the fastening process of the fastening structure of the air conditioner panel having the above configuration will be described.

First, after the panel 46 approaches the frame 40, the O-ring 54 and the concave washer 52 are prepared. Then, the rubber washer 50 is fastened tightly with the screw bolt 48 fitted. Finally, the cap 56 is covered to cover the screw bolt 48.

Although the present invention has been described with respect to specific embodiments, modifications that omit the O-ring 54 or replace it with other parts, modifications that replace or omit the rubber washer 50 with other similar parts, etc. It can come to mind in the mind of those skilled in the art. Therefore, such modifications should also be construed as falling within the scope of the present invention.

According to the fastening structure of the air conditioner panel according to the embodiment of the present invention as described above, the head of the bolt is not visible to the outside while maintaining the airtightness of the air conditioner thoroughly. Therefore, product quality and customer satisfaction can be improved.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Therefore, the scope of the utility model registration claims attached will include such modifications or variations that fall within the spirit of the present invention.
