DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted air conditioner.

[0002]

BACKGROUND ART One example of a conventional wall-mounted type air conditioner is shown in Fig. In FIG. 2 , reference numeral 1 denotes a casing, and 2 denotes a front panel mounted on the front side of the casing 1. The casing 1 and the front panel 2 constitute a unit body. 10 is a suction grill mounted on the front panel 2 around the pin 19 so that it can be opened and closed. 3 is a suction grill.
Reference numeral 10 denotes a heat exchanger, 4 denotes a through-flow fan disposed at a lower rear portion of the heat exchanger 3, 5 denotes an outlet formed at a lower portion of the front panel 2, and 6a and 6b denote blowers. A horizontal flap disposed at the outlet 5, a louver 7 disposed at the outlet 5, a drain pan 8 disposed below the heat exchanger 3, 9
Is an air filter disposed upstream of the heat exchanger 3, and 11 is a mounting plate made of sheet metal mounted on the upper part of the indoor wall surface 12.

[0003] Reference numerals 13a and 13b denote a pair of refrigerant pipes each having one end connected to the heat exchanger 3 and covered with a heat insulating material 14. Reference numeral 15 denotes a drain hose having one end connected to the drain pan 8, reference numeral 20 denotes a magnet catch provided at a lower rear portion of the casing 1, and reference numeral 21 denotes a magnet fixed to a lower front portion of the mounting plate 11.

The unit main body engages a locking portion 17 provided on an upper portion thereof with a hook portion 18 provided on an upper portion of the mounting plate 11, and then attracts a magnet catch 20 to a magnet 21 to thereby mount the mounting plate. It is installed on the wall 12 via 11.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 3. Then, the room air is sucked into the casing 1 from the suction grill 10, and dust contained therein when the air flows through the air filter 9 is removed. Then, in the process of flowing through the heat exchanger 3, the refrigerant exchanges heat with the refrigerant to be cooled or heated, and then sucked into the fan 4 to be energized. Then, the air is blown out from the air outlet 5 into the room.

[0006]

In the conventional air conditioner described above, when the refrigerant pipes 13a and 13b and the drain hose 15 are piped to the left during installation, the lower rear surface of the casing 1 and the installation plate 11 are connected. After being bent at a substantially right angle in the space 16 formed therebetween, it is drawn out of the room through a through hole formed in the wall 12, but at this time, the magnet catch 20 separates from the magnet 21 and the lower part of the unit main body. Is mounting plate 11
There was a problem that it would rise more.

[0007]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its gist is to hang on an upper part of a sheet metal mounting plate attached to a wall surface.
In the wall-mounted air conditioner in which a stop portion is provided, and the lock portion provided on the upper portion of the unit body is engaged with the hook portion and installed, the lower portion of the installation plate is substantially horizontally directed forward.
Form a pair of extending arms at right and left intervals
Of the rising part which rises from the front end of the pair of arms to a predetermined height
Tip to form a hook which is bent in a hook shape downward in front of the hook hole while drilling a hooking hole for hooking the hook in the lower vertical walls of the unit body
Part of the front panel is detachable,
Opening formed by removing part of the panel
And the driver etc. inserted through the hook hole
Insert the tip into the horizontally long insertion hole drilled in front of the hook
With the hook slightly raised above the unit body.
Part after pushing the part toward the installation plate
By pulling out the hook and the hook hole
A wall-mounted air conditioner characterized by being hooked on a lower edge .

[0008]

[0009]

In the present invention, the air conditioner is installed by engaging the hooks of the unit body with the hooks of the unit main body and engaging the hooks of the unit body with the hooks of the mounting plate.

[0010]

EXAMPLES real施例of the present invention is shown in FIG. A pair of arms 30 are integrally formed at the lower part of the sheet metal mounting plate 11 with a space left and right, and extend substantially horizontally toward the front.

At the tips of these arms 30, there are provided rising portions 31 which rise upward to a predetermined height, and at the tips thereof are provided hook portions 32 which are bent downward in a hook shape. On the front surface of the hook portion 32, a horizontally long insertion hole 33 for inserting a tip of a driver or the like is formed.

On the other hand, a hook hole 34 for hooking the hook 32 is formed in the lower vertical wall 1a of the casing 1, and a part 2a of the front panel 2 in front of the hole 34 is detachable.

When the air conditioner is installed, after the engaging portion 17 of the unit body is engaged with the engaging portion 18, the refrigerant pipes 13a, 13b and the drain hose 15 are mounted on the pair of arms 30. The unit body is turned counterclockwise in this state to bring the lower part thereof closer to the mounting plate 11.

Next, a part 2a of the front panel 2 is removed, a tip of a flat head screwdriver 35 is inserted into the insertion hole 33 through the hook hole 34, and the hook 32 is slightly lifted. When pushed toward 11, the hook 32 protrudes forward through the hook hole. Then, pull out the flathead screwdriver 35, and the hook 32
It is restored with an elasticity of 30 and hooked on the lower edge of the hook hole 34.

[0015]

[0016]

[0017]

According to the present invention, after the engaging portion provided on the upper portion of the unit body is engaged with the engaging portion provided on the upper portion of the mounting plate, the hook portion formed on the lower portion of the mounting plate is engaged. Can be hooked into the hook holes formed in the unit body, so that the installation work is easy and the lower part of the unit body can be reliably prevented from floating from the installation plate. Also,
Since the structure is simple and inexpensive, and the conventional magnet and magnet catch are not required, the cost can be reduced.
