An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes an indoor unit, which is connected to an outdoor unit (not shown) by a refrigerant pipe or a signal line to constitute a separation type air conditioner. 2 is a front side panel, 3 is a rear side panel, 4 is a suction grill rotatably attached to the front side panel,
An inlet 4A is formed. Reference numeral 5 denotes an air outlet, on which an air direction changing plate (horizontal blade) 6 is provided. still,
An exterior body is formed by the suction grille 4, the front panel 3, and the rear panel 2.

In FIG. 2, reference numeral 7 denotes a heat exchanger through which a refrigerant flows inside the heat transfer tube, which is formed in a substantially rectangular shape. Reference numeral 8 denotes a cross flow fan for passing indoor air through the heat exchanger and blowing out the temperature-conditioned air from the outlet, and 10 denotes an air filter for removing relatively large dust. It is exposed when moved and opened, and becomes detachable. Reference numeral 11 denotes an air purification filter for removing relatively small dust and odor, and reference numeral 12 denotes a drain pan for receiving drain from a heat exchanger. 21 and 21 are tube plates of the heat exchanger, both of which are formed of metal. The tube sheet 20 is hooked on a hook 22 of the main body, and the tube sheet 21 is screwed to the main body with screws 23. Reference numeral 24 denotes an opening provided in the tube sheet, which is also referred to as a steal, which is provided to make this portion easily elastically deformed. Note that vertical blades for changing the blowing direction of the temperature-controlled air are not shown.

In FIG. 3, reference numeral 25 denotes a stopper, and the stopper 27 presses and stops an end 27 of a heat insulating material 26 made of styrene foam. When viewed from the front, the stopper 25 hits the right end, but the left end does not have any equivalent to the pressing portion, and the left end is not pressed by the drain pan. Reference numeral 28 denotes a support for a wind direction changing plate attached to the blowout frame 29. The supporter includes a portion about one third of the width of the outlet from the left and a part about one third of the width of the outlet from the right. Can be attached to Reference numeral 30 denotes a holding portion of a drain pan provided on an upper portion of the support 28, which is screwed to the drain pan 12. When the screw 28 is fixed and the support 28 is attached at two places, the drain pan is also held down at two places.

FIG. 4 shows a side view of the support 28 alone, 35 is a support for the wind direction changing plate 6, 36 is a support for supporting the auxiliary wind direction changing plate 6A on the primary side of the wind direction changing plate 6, and 37. Is a stop portion that fits into the hole of the blowout frame 29 and is stopped, 38 is a screw hole, and 39 is a concave portion that fits into the reinforcing portion 29A of the blowout frame. The drain pan 12 and the blowout frame 29
And are integrally formed.

In the air conditioner configured as described above, the assembling of the blowing frame 29 is performed by first inserting the heat insulating material 26 into the stopper 25 of the drain pan 12 from an oblique direction, and inserting the heat insulating material 26 into the stopper. Is stopped by hooking. At this time, the end 27 of the heat insulating material 26 is
Of the heat insulating material 2 as compared with the conventional one in which the stoppers are provided on the left and right.
6 is not greatly curved. Therefore, damage such as cracking of the heat insulating material 26 is unlikely to occur.
Further, since the heat insulating material 26 is fixed by inserting only the end portion 27, the mounting of the heat insulating material 26 to the drain pan 12 is very easy. Thermal insulation 2 in drain pan 12
An adhesive is applied in advance to the contact portion with 6, and the left end of the heat insulating material 26 attached to the drain pan is not stopped, but is adhered so as not to come off. Then, a shaft is inserted into the left and right end portions of the blowout frame 29 to attach the auxiliary wind direction changing plate 6A, and the support member 28 is attached by fitting the stopper at the lower end thereof into the hole of the blowout frame 29. The shaft in the middle is fitted into the support portion 36, and the heat insulating material 26 is pressed by the holding portion 30 so that the screw hole 38 matches the screw hole of the drain pan. In this state, the support 28
Since is not screwed, it is in a state where it can be moved slightly in the front-back direction. Then, the shafts of the wind direction change plate 6 are fitted into the left and right ends of the blowout frame, and two shafts on the way are connected to the support 2.
8 is attached to the supporting portion 35. At this time, since the support 28 is not fixed, the shaft can be easily attached. After the shafts of the two wind direction change plates 6 are respectively fixed to the support portion 35 at two places, the concave portion 39 is fitted into the reinforcing portion 29A of the blowout frame 29, and the screw hole 38 is screwed. By this screwing, the fixing of the support 28 and the support 2
The support of the wind direction change plate 6 and the auxiliary wind direction change plate 6A supported by the support member 8 and the holding of the heat insulating material 26 are performed.

As described above, in the air conditioner according to the present invention, the mounting of the wind direction changing plate 6 and the auxiliary wind direction changing plate 6A and the holding of the heat insulating material 26 of the drain pan are performed by mounting the wind direction changing plate support 28. And can be done. For this reason, the assembly structure of the air conditioner can be simplified. Further, there is no need to separately provide a support for supporting the auxiliary wind direction changing plate 6A. The description of the installation of the vertical blade is omitted.

In such an air conditioner, when the fan is very dirty, it may be necessary to remove the fan. In this case, the suction grille 4, the front panel 2, and the left bearing (not shown) are removed, the hook (not shown) on the left side of the heat exchanger 7 is removed, and the right tube sheet 20 is hooked. After removal, heat exchanger 7
When the left side is slightly lifted to the front,
The fan 8 can be removed from the left side as shown in FIG. At this time, the opening 24 is provided in the tube sheet 21,
Since it is easily deformed elastically despite being metal, it is easy to move the heat exchanger 7.

[0018]

In the air conditioner according to the first to third aspects of the present invention, when the heat insulating material is attached to the mounting portion of the drain pan and the support for the wind direction changing plate is mounted to the blowout frame, the heat insulating material is simultaneously attached to the support. Since it is held by the holding portion, the holding of the heat insulating material and the support of the wind direction change plate can be performed, and the assembly of the air conditioner can be facilitated.

In the air conditioner according to the second aspect of the present invention, since the heat insulating material mounting portion is provided only on one side of the drain pan, the heat insulating material of the drain pan is mounted on only one side. Even if it is bent, the amount of this bending can be kept small, and damage to the drain pan during assembly can be prevented as much as possible.

In the air conditioner according to the third aspect of the present invention, since the support for the wind direction changing plate and the auxiliary wind direction changing plate is formed particularly on the support for the wind direction changing plate, the support of the wind direction changing plate and the auxiliary wind direction changing plate is provided. The heat insulating material can be held down at the same time, and there is no need to provide a special support for the auxiliary wind direction changing plate, so that the assembly and configuration of the air conditioner can be simplified.
