DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a bent portion and having a heat exchanger including an upper heat exchanger and a lower heat exchanger.

[0002]

2. Description of the Related Art Conventionally, in an air conditioner, as shown in FIG.
That is, it has an upper heat exchanger 1 and a lower heat exchanger 2. In order to maintain the upper heat exchanger 1 and the lower heat exchanger 2 in this heat exchanger at a predetermined angle, the upper heat exchanger 1
The bending angle holder 4 shown in FIG. 5 is fixed to the notch 3 of the lower heat exchanger 2 with the screw 7 on the end plate 6 of one of the heat exchangers 2. In the figure, 5 is an upper heat exchanger 1 and a lower heat exchanger 2
Is shown.

[0003]

In the above prior art,
In order to hold the upper heat exchanger 1 and the lower heat exchanger 2 at a predetermined angle, the bending angle holder 4 is screwed to the end plate 6 of the heat exchanger.
The structure is such that the bending angle is held by using a fixing member, so that the number of parts is increased, the number of steps for assembling is increased, and the angle must be adjusted when attaching the bending angle holder 4. is there.

An object of the present invention is to provide an air conditioner which can easily adjust a bending angle of a heat exchanger having a bent portion and has a small number of parts for adjusting the angle, in consideration of the conventional problems. .

[0005]

In order to achieve the above object, the present invention provides a notch at a predetermined position in a row of fins in a longitudinal direction, and an upper heat exchanger above the notch and a lower part below the notch. The heat exchanger includes a heat exchanger connected in the center, and a convex portion formed on the back of the front frame of the air conditioner body is inserted into a notch of the heat exchanger to define an upper heat exchanger and a lower heat exchanger. Angle. In addition, on the upper surface and the lower surface of the convex portion, provided at regular intervals in the longitudinal direction of the front frame, and a lower surface facing the cutout portion of the upper heat exchanger, and a projection portion contacting the upper surface facing the cutout portion of the lower heat exchanger. Configuration.

[0006]

The operation of the above means is as follows. By inserting the convex portion formed on the back surface of the front frame constituting the air conditioner main body into the notch portion of the heat exchanger, a predetermined angle between the upper heat exchanger and the lower heat exchanger can be maintained. No special angle adjustment parts are required. Further, since the projection provided on the projection of the front frame abuts on the lower and upper surfaces of the upper heat exchanger and the lower heat exchanger in the cutout portion of the heat exchanger, when heat is exchanged in the upper heat exchanger. Then, the projections guide the dew water generated on the upper heat exchanger surface to the lower heat exchanger, and quickly flow down.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. Note that the same reference numerals are used for the same components as those shown as the conventional example. As components, 5 is a heat exchanger, 8 is a fan, 9 is a water tray, 10 is a blowout grill, 1
1 is a front grill, 12 is a front frame.

Here, a notch 3 is provided at the center of the heat exchanger 5 and comprises an upper heat exchanger 1 above the notch 3 and a lower heat exchanger 2 below the notch 3. 1
And the lower heat exchanger 2 are bent so as to have an angle at a predetermined position in the longitudinal direction of the fin 15. Note that the fins 15 connect the upper heat exchanger 1 and the lower heat exchanger 2. On the back surface of the front frame 12 and at a position corresponding to the notch 3, a tapered convex portion 13 to be inserted into the notch 3 is provided. Protrusions 14 are provided at equal intervals in the longitudinal direction and are in contact with the lower surface of the upper heat exchanger 1 facing the cutout 3 and the upper end of the lower heat exchanger 2.

In the above configuration, the air sucked from the front grill 11 exchanges heat with the heat exchanger 5, and is blown out from the blow grill 10 through the fan 8. At this time, a predetermined angle between the upper heat exchanger 1 and the lower heat exchanger 2 can be maintained only by inserting the protrusion 13 formed on the front frame 12 into the notch 3 of the heat exchanger 5.

Further, the projections 14 provided on the projections 13 guide the condensed water 16 generated on the surface of the upper heat exchanger 1 to the lower heat exchanger 2 and quickly flow down.

[0011]

As is apparent from the above description of the embodiment, the present invention allows the predetermined bending angle of the heat exchanger to be adjusted only by inserting the projection formed on the front frame into the notch of the heat exchanger. Can hold. Therefore, a bending angle holder is not required, the number of parts can be reduced, the cost can be reduced, and the number of steps in assembling can be reduced.

Further, the condensed water generated on the surface of the upper heat exchanger is guided to the lower heat exchanger by the protrusion provided on the convex portion, and quickly flows down, so that the condensed water is formed in the notch of the heat exchanger. It is possible to eliminate the occurrence of a market claim that overflows and drops from the air conditioner.
