Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a wall-mounting device for mounting an air conditioner on a wall surface.

(b) Prior Art Conventionally, this type of wall hanging device as shown in FIGS. 1 to 6 has been proposed. In Figure 1, 1
The air conditioner is composed of a main body 2 and a front panel 3 fitted to the front of the main body, and includes an indoor heat exchanger 4, a blower 5, a drain pan 6, etc. shown in FIG. 2. Both the main body 2 and the front panel 3 are made of synthetic resin, and 7 is the front panel 3.
9 is an air inlet formed in the upper part of the front panel 3 and has an air filter 8; 9 is an outlet formed in the lower part of the front panel 3 and has a wind direction changing plate 10; 11 is a back plate 1 of the main body 2;
2 fitting parts integrally molded on the left and right sides of the upper part, 13 having protrusions integrally molded at 4 places at the same height as these two fitting parts, and 14 receiving drains attached to the back plate 12. This is the guide part that carries water. In Figure 3, 15 is a wall hanging board made of sheet metal that is fixed to the indoor wall.
A horizontal piece 16 and hanging pieces 17 formed by cutting and raising a portion of the left and right sides of this horizontal piece are separately formed on the upper edge.

Then, lift the air conditioner 1 and
Hanging piece 17 of wall hanging board 15 fixed with screw 19
Insert the lower openings 20 of both fitting parts 11 into the
At the same time as the horizontal piece 16 is locked to this fitting part 11,
The air conditioner 1 is mounted on the wall hanging board 15 by placing the protrusion 13 on the wall.

Figures 4 and 5 show the first position in the above-mentioned mounting state.
This mounting state will be described in detail below with reference to -' and -' cross-sectional views of the figure. On the upper part of the back plate 12, as shown in FIG. 5, a horizontal piece 16 is placed with a protrusion 13, so that the weight of the air conditioner 1 is equally divided among the four protrusions 13. Therefore, each of the protrusions 13 only needs to be strong enough to withstand a relatively light load.

Further, as shown in FIG. 4, the upper ends of the back plate 12 are fitted with locking pieces 17 inserted through the lower opening 20 and brought into contact with the inner wall 21 of the fitting part 11 to restrict the movement of the air conditioner 1 in the front-rear direction. It's summery. In addition, this fitting part 11
A sealing material 23 was attached to the main body opening 22 from the front of the main body 2 to prevent air heat exchanged in the indoor heat exchanger 4 from leaking.

(c) Problems with conventional technology When using the indoor heat exchanger 4 as a cooler,
As shown in FIG. 4, the drain 25 adhering to the top plate 24a of the main body 2 flows down to the back surface 26 of the wall-hanging plate 15 via the outer wall 24b of the fitting part 11 and the hanging piece 17 of the wall-hanging plate 15, and flows down to the back surface 26 of the wall-hanging plate 15. It had the disadvantage of getting 18 wet. In order to eliminate this drawback, as shown in FIG. 6, an upper opening 27 through which the drain 25 adhering to the top plate 24a drips downward, and an eaves 28 covering the latch piece 17 are installed from the inner wall 29 of the fitting part 11'. A structure has been proposed that projects forward and covers the upper part of the locking piece 17. However, the formation of the eaves 28 inevitably complicates the mold for manufacturing the main body 3. In addition, the manufacturing process of the main body 3 is complicated by the attachment of the sealing material 23, and there is a risk that this sealing material may be peeled off by the cold air inside the main body 3 and the drain 25 that adheres to and drips from the top plate 24a.

(d) Purpose of the invention The dew that adheres to the top plate of the main unit is guided to the back plate of the main unit without being transmitted to the wall hanging board.

(E) Key points of the invention The invention includes a cylindrical engagement part into which the locking piece of the wall-mounted plate fits from below into the main body of the air conditioner, and a dew guide part located on the outer periphery of this engagement part. The drain water adhering to the outer peripheral surface of the engaging part is made difficult to be transmitted to the wall plate, and the drain water is guided to the back plate of the main body via the dew guide part.

(F) Embodiment of the invention Figures 7 to 10 show an embodiment of the invention, in which 30 is a dew guide portion formed by recessing a part of the top plate 32 of the main body 31 made of synthetic resin; 33 is a back plate whose back surface of the main body is integrally closed with synthetic resin, 34 is a dew guide wall located at the rear of the dew guide part 30 and stands upwardly, and 35 is a cylindrical engagement formed integrally with this back plate. The upper opening 3 is provided with a locking piece 36 that extends from the dew guide wall 34 to the left and right rearward and faces the back plate 33.
7 and a lower opening 38. 39 is a refrigerant pipe connected to the indoor heat exchanger 4. The same parts as those in the conventional example described above are given the same reference numerals, and their explanations are omitted.

The air conditioner 40 is attached to the hanging piece 1 of the wall hanging board 15.
7 is attached to the indoor wall 18 in a state in which the locking piece 36 is locked to the inner peripheral back wall 41. Therefore, the drain 42 accumulated in the dew guide portion 30 is guided to the dew guide wall 34 as shown by the solid line arrows in FIGS. 9 and 10, and then transferred to the back plate 3
3 to the guide section 14, and this drain 4
2 is not likely to be transmitted to the locking piece 17. Also, the inner peripheral back wall 41 of the locking piece 36 that the locking piece 17 is in contact with
Since the back plate 33 of the main body 31, which has been cooled and is in an exposed state, is connected only by the side wall 43 of the engaging portion 35, heat conduction from the back plate 33 to the inner peripheral back wall 41 is small. The phenomenon of dew condensation due to cooling is less likely to occur on this inner circumferential rear wall 41.

Incidentally, the upper opening 37 of the engaging portion 35 described above may be in a closed state as shown in FIG. 4.

(g) Effects of the device As described above, the device has a cylindrical engaging portion on the main body and a dew guide portion that guides the drain adhering to the outer peripheral surface of the engaging portion to the back plate of the main body. The locking piece of the wall-hanging plate is fitted from below the cylindrical engaging part, and the rear part of this engaging part is brought into contact with the locking piece of the wall-hanging plate, so that the drain attached to the outer peripheral surface of the engaging part is prevented. It is possible to prevent the condensate from being transmitted to the wall-mounted board, and moreover, the condensate can be guided to the back plate of the main body by the dew guide section.
