Description

[Detailed description of the invention] The present invention relates to an air conditioner in which a board on which a unit part is mounted is inserted into an outer casing along a guide rail formed on the bottom of the outer casing. This prevents noise from propagating to the outer casing and causing abnormal noise.

To explain a conventional air conditioner with reference to Fig. 1, 1 is the main body of the air conditioner, 2 is a generally mouth-shaped outer casing with an open front, 3 is a board inserted into this outer casing 2, and 4 is the same. The unit part mounted on the substrate 3 includes an indoor heat exchanger 5, an outdoor heat exchanger 6,
It consists of fans 7 and 8 provided opposite to the heat exchangers 5 and 6, an electric motor 9 and a compressor 10 that drive both the fans 7 and 8.

11 is a front panel that closes the front opening of the outer casing 2;

The outer casing 2 has both bottom sides bent inward to form flange portions 12, 12, and an inward portion for inserting the board 3 into the flange portions 12, 12, respectively. A protruding guide rail 13 is formed, and the outer casing 2
When inserting the board 3 inside the housing, the board 3 is inserted horizontally from the front opening of the outer casing 2 along the guide rail 13, and then the front panel 11 is attached.

Therefore, the board 33 is placed directly on the guide rail 13 of the outer casing 2, and when the main body 1 is operated, the unit part 4
The vibrations of the electric motor 9, compressor 10, etc. inside are propagated to the outer casing 2 via the board 3 and guide rail 13, and further to the mounting base (not shown) on which the main body 1 is installed, causing abnormal noise. This caused discomfort to the user.

In view of the above points, the present invention is intended to prevent vibrations of the electric motor 9, compressor 10, etc. in the unit section 4 from propagating to the outer casing 2 and causing abnormal noise.

An embodiment of the present invention shown in FIGS. 2 and 3 will be described below.

1 to 13 are the same as before. Reference numeral 14 indicates a screw hole located near the guide rail 13 formed in the flange portions 12, 12 and formed at least in the front thereof, and 15 indicates a screw hole 1 of the same.
4 is a bolt provided so as to be freely retractable from below, and a buffer member 16 is provided at the top end of the bolt.

When inserting the board 3 into the outer casing 2 in the above configuration, first lower the bolt 15 so that the upper surface of the buffer member 16 is flush with the upper surface of the guide rail 13.

Next, insert the board 3 into the guide rail 13 through the front opening of the outer casing 2.
, and then attach the front panel 11.

Then, raise the bolt 15 and move the board 3 onto the guide rail 1.
3. Float upward.

At this time, since the board 3 is placed on the buffer member 16 of the bolt 15, vibrations of the electric motor, compressor 10, etc. in the unit section 4 are transmitted to the buffer member 16 through the board 3 when the main body 1 is in operation.
It is absorbed into the outer casing 2 and does not propagate to the outer casing 2.

As described above, in the present invention, in an air conditioner in which a board on which a unit part is mounted is inserted into an outer casing along a guide rail formed on the bottom surface of the outer casing, An appropriate number of bolts with buffer members at their tips are installed from below, and after the board is inserted, the bolts are raised to float the board above the guide rail, so the board can be placed on the bolts. Since the vibrations from the unit are not propagated to the outer casing and are absorbed by the buffer member provided on the bolt, it is possible to prevent abnormal noises that conventionally occur.

[Brief explanation of the drawing]

Fig. 1 is an exploded perspective view of a conventional air conditioner, Fig. 2 is a partially cutaway perspective view of an outer casing showing an embodiment of the present invention, and Fig. 3 is an exploded perspective view of a conventional air conditioner.
The figure is a sectional view of a main part showing a state in which the board is inserted into the outer casing. In the figure, 2 is an outer casing, 3 is a board, 4 is a unit part, 13 is a guide rail, 15 is a bolt, and 16 is a buffer member.

Claims (1)

[Scope of utility model registration request] In an air conditioner comprising a board on which a unit part is mounted and an outer casing having a guide rail formed on the bottom surface protruding inward for inserting the board inside, the guide rail is formed on the bottom surface of the outer casing. An appropriate number of bolts having a buffer member at their tips are provided near the board so that they can come out and go out from below, and after the board is inserted, the bolts are raised to float the board above the guide rail. harmonizer.
