Abstract

PURPOSE:To permit the retention of an angle between an upper heat exchanger and a lower heat exchanger at a predetermined angle without employing any special angle regulating part and permit the downflow of condensate quickly by a method wherein projections, formed on the rear surface of a front frame constituting the main body of an air-conditioning machine, are inserted into notches of the heat exchanger. CONSTITUTION:A heat exchanger 5 in the indoor unit of an air-conditioning machine is constituted of an upper heat exchanger 1, positoned at upper part of notches 3 provided at the central part, and a lower heat exchanger 2, positioned below the notches 3, while both heat exchangers 1, 2 are bent at a predetermined position in the lengthwise direction of a line 15 so as to have an angle. Truncated conical projections 13, inserted into the notches 3, are provided at positions on the rear surface of a front frame 12 and opposed to the notches 3 while protuberances, abutted against the lower surface of the upper heat exchanger 1 and the upper end of the lower heat exchanger 2, are provided at the upper and lower surfaces of the projections 13. According to this method, both of the heat exchangers 1, 2 are retained with a predetermined angle while condensate 16, generated on the surface of the upper heat exchanger 1, can be dropped quickly through the lower heat exchanger 2.

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 composed of 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. 4, a heat exchanger having a bent portion which is cut out at a predetermined position,
That is, the upper heat exchanger 1 and the lower heat exchanger 2 are provided. In order to keep 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 was fixed to the end plate 6 of one heat exchanger 2 with the screw 7 in the notch 3 of the lower heat exchanger 2. In the figure, 5 is an upper heat exchanger 1 and a lower heat exchanger 2.
It shows a heat exchanger composed of.

[0003]

SUMMARY OF THE INVENTION In the above conventional technique,
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.
Since it has a structure for holding the bending angle by fixing it by using, there is a problem that the number of parts increases, the number of man-hours at the time of assembling is large, and the angle must be adjusted when the bending angle holder 4 is mounted. is there.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an air conditioner in which the bending angle of a heat exchanger having a bending portion can be easily adjusted and the number of parts for adjusting the angle is small. .

[0005]

To achieve the above object, the present invention provides a notch at a predetermined position of a fin array in the longitudinal direction, and an upper heat exchanger above the notch and a lower part below the notch. The heat exchanger is provided with a heat exchanger connected at the center, and the convex portion formed on the back surface of the front frame of the air conditioner body is inserted into the notch of the heat exchanger to determine the upper heat exchanger and the lower heat exchanger. The configuration is maintained at the angle of. Further, on the upper surface and the lower surface of the convex portion, a lower surface facing the notch of the upper heat exchanger and a protrusion contacting the upper surface facing the notch of the lower heat exchanger are provided at regular intervals in the longitudinal direction of the front frame. It has a different 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 that constitutes the air conditioner main body into the cutout portion of the heat exchanger, it is possible to maintain a predetermined angle between the upper heat exchanger and the lower heat exchanger. No special angle adjustment parts are required. Further, since the protrusion provided on the convex portion of the front frame abuts the lower surface and the upper surface of the upper heat exchanger and the lower heat exchanger at the notch in the heat exchanger, when heat exchange is performed in the upper heat exchanger. In addition, the projections guide the condensed water generated on the surface of the upper heat exchanger to the lower heat exchanger, and quickly drop it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 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, and 1
Reference numeral 1 is a front grill, and 12 is a front frame.

Here, the heat exchanger 5 has a notch 3 in the center thereof, and comprises an upper heat exchanger 1 above the notch 3 and a lower heat exchanger 2 below the notch 3, and this upper heat exchanger 1
The lower heat exchanger 2 and the lower heat exchanger 2 are bent so as to form an angle at a predetermined position in the longitudinal direction of the fin 15. The fins 15 connect the upper heat exchanger 1 and the lower heat exchanger 2. A tapered convex portion 13 to be inserted into the cutout portion 3 is provided on the back surface of the front surface frame 12 and at a position corresponding to the cutout portion 3. 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 and the upper end of the lower heat exchanger 2 which face the notch 3.

In the above structure, the air sucked from the front grill 11 is heat-exchanged by the heat exchanger 5 and blown out from the blow-out grill 10 through the fan 8. At this time, the predetermined angle between the upper heat exchanger 1 and the lower heat exchanger 2 can be maintained only by inserting the convex portion 13 formed on the front frame 12 into the cutout portion 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 it down.

[0011]

As is apparent from the above description of the embodiments, according to the present invention, a predetermined bending angle of the heat exchanger can be obtained only by inserting the convex portion formed on the front frame into the notch portion 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 man-hours for assembling can be reduced.

Further, the dew condensation water generated on the surface of the upper heat exchanger is guided to the lower heat exchanger by the protrusions provided on the convex portion and is quickly drained off, so that the dew condensation water is formed at the notch of the heat exchanger. It is possible to eliminate the occurrence of market complaints that overflow and drip from the air conditioner.
