Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the structure of a heat exchange unit whose exterior body is composed of a frame and a front cover attached to the front part of the frame.

(b) Prior Art Conventionally, an example of the structure of this type of heat exchange unit has been disclosed in Japanese Utility Model Application Publication No. 17752/1983.

According to this content, the air passage inside the exterior body of the heat exchange unit is constituted by the outer wall of the drain pan inside this exterior body and the wind guide plate of this exterior body, and the air passage inside the exterior body of the heat exchange unit is constituted by the outer wall of the drain pan inside this exterior body and the wind guide plate of this exterior body, and the air passageway inside the exterior body of the heat exchange unit is constituted by the outer wall of the drain pan inside this exterior body and the wind guide plate of this exterior body. The upper piece was fitted into the recess of the drain pan, and the lower piece was fixed to the end of the wind guide plate. Then, the edge of the air outlet of the front cover was fitted into this frame.

(c) Problems to be solved by the invention In such a heat exchange unit, the vicinity of the outlet of the air passage has three parts: the drain pan, the frame, and the air outlet.
Since it is formed by fitting parts together, it is difficult for the air passage to have a smooth shape.

The purpose of the present invention is to connect a front cover to a drain pan in a frame to form an air passage within a heat exchange unit.

(d) Means for solving the problem In order to achieve this objective, the present invention consists of an exterior body consisting of a frame and a front cover attached to the front part of the frame, and the front cover is attached to the frame. The drain pan is provided with an air outlet connected to the outer wall of the inner drain pan, and an engagement piece that is engaged with the drain pan.

(E) Function By engaging the front cover with the drain pan, the two are integrally combined, and the outer wall of the drain pan and the outlet of the front cover are smoothly connected.

(f) Embodiment In FIGS. 1 and 2, 1 is an indoor unit of a separate air conditioner that incorporates an indoor heat exchanger 2, a cross flow fan 3, etc., and the exterior body of this unit is a frame 4, The frame includes a front cover 5 attached to the front side of the frame. 6 is a suction port of this front cover 5, and a grill member 7 is attached to the front surface of this suction port. The grill member 7 and the protruding portion 8 of the front cover 5 are arranged to be substantially flush with each other. Reference numeral 9 denotes a drain pan, which is disposed below the heat exchanger 2. The outer wall 10 of this drain pan 9 and the guide plate 11 of the frame 4
and the air passage 12 on the discharge side of the cross flow fan 3.
is configured. The drain pan 9 is attached to the frame 4 at both left and right ends (not shown), so that the frame 4 and the drain pan 9 are integrated. Reference numeral 13 denotes an engaging member attached to the front edge 14 of the drain pan 9, and a horizontal piece 15 extending forward is provided at the lower part of this member. A locking piece 17 protruding from the back surface 16 of the front cover 5 engages with this horizontal piece 15. 1
8 is the air outlet of this front cover 5;
The upper wall 19 of the air outlet 18 is connected to the outer wall 10 of the drain pan 9 in a state where the locking piece 17 is locked to the horizontal piece 15 of the engaging member 13 of the drain pan 9. That is, when the front cover 5 is engaged with the drain pan 9, the upper wall 19 of the air outlet 18 of the front cover 5 is connected to the outer wall 10 of the drain pan 9, so that the inner wall of the air passage 12 forms a smooth curve. .

The front cover 5 is fixed to the drain pan 9 at two locations in the lateral direction of the heat exchange unit 1 (the locations shown in Figure 1), and most of the other parts are as shown in Figure 3. There is. That is, 19 is a gasket attached to the front surface 20 of the drain pan 9 to fill the gap between the front surface 20 of the drain pan 9 and the front cover 5. A heat insulating material 21 is fitted into a triangular space 23 formed by the wind guide piece 22 of the drain pan 9 and the front wall 20.

As shown in FIG. 1, this drain pan 9 has a frame-shaped air outlet 24 integrally molded on its lower side, with vertical blades 26 on the lower side 25 and horizontal blades 28 on the side sides 27. Supported. This lower side 2
The upper edge 29 of 5 is placed against the lower edge 30 of the wind guide plate 11 of the frame 4, and the protruding piece 31 under this lower side 25
is engaged with the engagement hole 32 of the wind guide plate 11. or,
The lower side 24 of this air outlet is fixed to the wind guide plate 11 of the frame 4 with screws at a location other than where the protruding piece 31 is formed. 33 is the lower side of the air outlet 18 of the front cover 5 and is connected to the lower side 25 of the air outlet 24 which is integrated with the drain pan 9.

(g) Effects of the invention As described above, in the present invention, the exterior body of the heat exchange unit is composed of a frame and a front cover attached to the frame, and when this front cover is engaged with the drain pan inside the frame, Since the outlet of this front cover is connected to the outer wall of the drain pan, the inner wall of the air passage formed by the outer wall of the drain pan and the outlet of the front cover has a smooth curved surface, which reduces the resistance of the wind flowing inside this air passage. It can be kept small. In addition, since the air outlet of the front cover is directly connected to the drain pan and the number of parts constituting the air passage is reduced, it is possible to reduce the possibility of variations when assembling the heat exchange unit.
