Description

[Detailed Description of the Invention] This invention relates to an air conditioner with an improved fan casing structure.

In a conventional wall-mounted air conditioner, as shown in FIGS. 1 and 2, fan motors C, C are fixed to a back plate formed separately from the main body a.
For example, turbo fans d and d are attached to the motor shaft of C.

The fan casings e, e of the turbo fans d, d are integrally formed with the main body a, together with the bell mouths f, f, and the back plate to which the fan motors C, C and the turbo fans d, d are attached is the main body a. It is designed to be attached to the

A heat exchanger g is provided inside the main body a, facing the turbo fans d and d, and a front panel h is attached to the front surface.

The front panel h is provided with an inlet i and an outlet j, and the turbofans d and d suck air from the inlet i into the body a through the heat exchanger g into the fan casing. After changing the direction toward the outer circumference by e and e, the air is blown into the room again from the air outlet j.

In this way, the turbo fans d, d are cooled by constant contact with the air cooled by the heat exchanger g. A heat insulating material k is attached to the inside of the upper and side surfaces of a to prevent dew condensation on the surfaces of these surfaces.

However, in the past, as mentioned above, the back plate was made separate from the main body a, and the fan casings e, e of the turbo fans d, d provided on the back plate were formed integrally with the main body a. Not only are the members to which the heat insulating material k is to be attached dispersed, but the direction of attachment is also inconsistent, making the attachment work a tedious task, which poses manufacturing and functional problems.

This idea was made in consideration of the above circumstances, and its purpose is to integrally mold the main body that supports the fan motor and the fan, and the fan casing that surrounds the fan, and to By protruding a recess for filling insulation material between the fan casing and the side wall of the main unit, the direction of the insulation material can be fixed, and the fan and fan casing can be installed with an accurate positional relationship. This is what we are trying to provide.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In the figure, reference numeral 1 denotes a main body, and fan motors 2, 2 are attached to the back of the main body 1, and fans, for example, turbo fans 3, 3, are provided on the motor shaft.

The fan casings 4, 4 of the turbo fans 3, 3 are molded from synthetic resin, and are formed to surround the turbo fan 3.3, and are also connected to the outer walls 4a of the fan casings 4, 4 and the outer wall 1a of the main body 1. Four parts 6, 6 for filling the heat insulating material 5 are provided between the two parts.

Also, two turbo fans 3 are installed in the fan casings 4, 4.
, 3 is formed, and this recess 7 can also be filled with a heat insulating material 5.

A separately formed bell mouth 8 is attached to the front surface of the fan casings 4, 4.

Further, a heat exchanger 9 is provided inside the main body 1 facing the turbo fans 3, 3, and a front panel 10 is attached to the main body 1 in front of the heat exchanger 9.

The front panel 10 is provided with an inlet 11 and an outlet 12.

Next, the assembly procedure of the above embodiment will be explained.

First, the fan motors 2, 2 are fixed to the inside of the back surface of the main body 1.

Then, the turbo fans 3, 3 are attached to the motor shafts of the fan motors 2, 2.

Next, after the bell mouth 8 is attached to the fan casings 4, 4, the heat exchanger 9 is attached inside the main body 1.

Next, a heat insulating material 5 is attached to the back surface of the main body 1, and the recess 6 surrounding the fan casings 4 and the four parts 7 of the partition wall are filled with the heat insulating material 5.

Finally, the front panel 10 is attached to the main body 1 to complete the assembly work.

In addition, in this state, the heat insulating material 5 will be in close contact with the installation surface, so it is possible to reduce the absorption of operational noise and vibration.
You can drive comfortably.

As explained above, according to the present invention, a fan casing surrounding the fan is integrally molded into a main body provided with a fan motor and a fan, and a heat insulating material is attached between the fan casing and the side wall of the main body. Since the concave portion is formed, the filling direction of the heat insulating material is unified.

Therefore, the heat insulating material can be easily installed and the number of man-hours can be reduced.

Furthermore, the fan casing and the heat insulating material can be integrally foam-molded, making it easier to manage the gap between the fan and the fan casing, resulting in improved fan characteristics.
