Description

[Detailed Description of the Invention] The present invention relates to a wall-mounted air conditioner that is fixed to the wall of an air-conditioned room and performs cooling or heating.

In recent years, when installing an air conditioner, ceiling-suspended or wall-mounted air conditioners have come into widespread use in order to minimize the installation space indoors.

However, once such a ceiling-hanging type or wall-hanging type is installed, it is extremely difficult to remove it because of its high location and the presence of piping.

In other words, if an electrical component such as a fan motor breaks down, it is necessary to remove the refrigerant piping from the main body and then lower it from a high place.

Such work places a heavy burden on workers and has serious defects that prevent smooth service delivery.

In view of this, the present invention provides a fan casing in which the fan and fan motor are fixed in advance so that it can be inserted and removed without removing the main body from the wall, so that service in the event of fan motor failure can be performed smoothly. The aim was to provide an air conditioner that is easy to work with and allows the fan motor to be always positioned at a predetermined position.

An embodiment of the present invention will be explained below with reference to the attached drawings. In the drawings, 1 indicates a wall-mounted air conditioner (indoor unit), and a mounting plate 3 fixed to a wall 2 of the air-conditioned room is attached to the back side. It is fixed by locking the locking part 4 provided in the.

A suction grill 5 is removably provided at the front inlet of the main body 1, and an outlet grill 6 is provided at the lower outlet.

That is, the suction grill 5 is attached to and detached from the upper and lower ends of the main cabinet 1', which is formed in an abbreviated shape, using screws, and the outlet grill 6 is also attached and detached from the front and rear surfaces using screws 7 and 8, respectively. It is provided.

A heat exchanger 9 is provided facing the intake grille 5, and is attached to the cabinet 1' with a predetermined space A provided between it and the inner surface of the back wall of the cabinet 1'.

Since the cabinet 1' is L-shaped, the space A has an opening B at the lower end as shown in the figure.

Reference numeral 10 is a dew pan provided at the lower end of the heat exchanger 9, and reference numeral 11 is a filter that is detachably provided between the suction grill 5 and the heat exchanger 9.

The predetermined space A is provided with a fan assembly 12 that can be inserted into and removed from the opening B.

That is, this fan assembly 12 includes a fan casing 13 having an inlet 13a formed facing the heat exchanger 9 and an outlet 13b formed facing the opening B, and a fan disposed inside the casing 13. 14 and a motor 15.

The motor 15 is mounted on its rotating shaft so as to be located inside the fan 14, and a mounting plate 16 to which the motor 15 is fixed is screwed to the outer edge of the fan casing 13. It is constructed so that it does not stand out.

Therefore, the fan assembly 12 is inserted into the predetermined space A through the opening B, and the lower end is secured to the casing 1 by screws 17.
It is screwed to an angle 18 that extends from '.

On the other hand, in the predetermined space A, a heat insulating material 19 of a predetermined thickness is applied in advance to the inner surface of the back wall of the casing 1'.
Further, aluminum foil 20 is coated over the entire surface of this heat insulating material 19.

This aluminum foil 20 prevents the fan assembly 12 from getting caught on the heat insulator 19 when inserted, and the heat from the auxiliary heater 21 placed behind the heat exchanger 9 is transferred to the heat insulator 19.
Alternatively, the heater 21 may be
The heat is radiated to reach the discharge port.

22.22 is a semicircular pressing plate located above and below where the mounting plate 16 of the fan motor 15 is located, and is provided so as to press the heat insulating material 19 and the aluminum foil 20.
It is pressed and fixed by a screw 24 to a mounting portion 23 that extends from ''.

Therefore, when the fan assembly 12 is inserted into the space A,
The mounting plate 16 slides on the suppression plate 22 and stops at a portion where there is no pressure plate 22, thereby determining its position. When the fan assembly 12 is inserted in this way, the heat insulating material near where the mounting plate 16 is located is fixed. There is a possibility that the heat insulating material 19 may swell up and come into contact with the fan 14, but the suppression plate 22 prevents the heat insulating material 19 from rising, and no accidental contact with the fan 14 will occur.

As described above, the side outlet grille 6 is connected to the fan assembly 12.
After installing, it is fixed with screws 7 and 8.

This grill 6 is the outlet 1 of the fan casing 13.
A ventilation passage 25 is formed which communicates with the cooling air passage 3b, and a horizontal louver 26 is provided in the ventilation passage 25, and a vertical louver 27 is provided in the cooling air discharge portion.

The wall 28 forming the ventilation passage 25 is made of a heat insulating material, and a heater 29 is embedded therein to prevent perspiration.

Therefore, as is clear from the above explanation, in the event of a contact accident with the fan 14 or a failure of the motor 15, the screws 7 and 8 of the outlet grille 6 can be removed without removing the main body 1 from the wall 2.
After removing the screws 17, the fan assembly 12 can be pulled out.

As is clear from the above explanation, the wall-mounted air conditioner of the present invention has a lower surface between the inner surface of the back wall of the cabinet fixed to the wall and the heat exchanger provided facing the suction port on the front of the main body. A fan casing with a fan and a fan motor provided in the predetermined space is provided in the predetermined space so as to be insertable and removable from the lower surface opening, a heat insulating material of a predetermined thickness is provided on the inner surface of the back wall of the cabinet, The present invention is characterized in that pressing plates are provided above and below the fan motor or a mounting plate for fixing the fan motor to press the heat insulating material toward the cabinet, so that the inconvenience of the fan or fan motor can be avoided. In addition to improving the serviceability of the fan casing, the position of the fan motor is fixed by the press plate when inserting the fan casing, and the insulation material will not be caught and damaged. This has great practical effects, such as eliminating accidents caused by contact with fans due to swelling.
