Description

The present invention relates to a heat exchange unit containing a heat exchanger, a drain pan, a cross flow fan and the like.

(B) Conventional technology In recent years, the thickness of the indoor heat exchange unit of the separation type air conditioner installed on the indoor wall surface has been reduced, and Japanese Patent Publication No. 62-46715 has been developed.
As shown in the publication, a cross flow fan is disposed above and behind the drain pan in the heat exchange unit. Accordingly, the rear piece of the drain pan is inclined obliquely upward so as to face the cross flow fan, and the rear piece is used as a tongue of the drain pan.

(C) Problems to be Solved by the Invention When the rear piece of the drain pan is inclined obliquely upward as described above, the direction of pulling out the mold of the drain pan also becomes obliquely upward, and the front piece of the drain pan is inevitably It is in a state of being inclined obliquely upward. When the front piece of the drain pan is inclined upward as described above, the depth dimension of the drain pan (the dimension from the lower end of the drain pan to the upper end of the front piece) is reduced, so that drain water is easily spilled, and the drain water leaks from the heat exchange unit. There was a fear.

In order to increase the depth of the drain pan, if the length of the front piece of the drain pan is increased, the depth of the drain pan may be increased, and as a result, the heat exchange unit may be thickened.

The present invention provides a drain pan in which a tongue of a cross flow fan arranged above and behind a drain pan is also used as a rear piece of the drain pan. The depth of the drain pan is set large to prevent drain water from spilling from the drain pan. It is intended to do so.

(D) Means for Solving the Problems In order to achieve this object, the present invention provides a heat exchanger,
In a heat exchange unit that accommodates a drain pan disposed below the heat exchanger and a cross flow fan disposed above and behind the drain pan, a lower side connected to a lower side of the drain pan and an oblique side facing the cross flow fan A tongue member having an upwardly-facing upper side is provided, and the tongue member is detachably attached to the rear of the rear piece of the drain pan.

(E) Action A mountain-shaped tongue member having a lower side connected to the lower side of the drain pan and an upper side facing obliquely upward facing the cross flow fan is molded separately from the drain pan, and the tongue member is detachably attached to the rear piece of the drain pan. The front and rear pieces of the drain pan can be extended in the vertical direction. This increases the depth dimension of the drain pan.
In addition, the tongue member having the optimal shape can be selected and used to improve the blowing performance, and the tongue member can be a minimum necessary member, which is economical.

(F) Embodiment In FIGS. 1 and 2, reference numeral 1 denotes an indoor unit of a separation type air conditioner, a heat exchanger 2, a drain pan 3 arranged below the heat exchanger, and a blower on the indoor side. 4 (hereinafter referred to as “cross flow fan”). The housing 5 of the indoor unit 1 includes a main body 6 and the main body 6.
, And a suction member 8 attached to the front panel 7. Reference numeral 9 denotes an auxiliary suction port provided on the front panel 7 and an upper portion of the suction member 8;
Is the main suction port provided in the suction member 8, and 11 is these suction ports 9, 10
The air filter 12 housed on the back side of the air outlet 12 is provided with a wind direction changing blade 13 at a discharge port. Reference numeral 14 denotes a support member for supporting the blades, and a lower portion 15 is sandwiched between the main body 6 and the front panel 7. The support member 14 is formed integrally with the drain pan 3 described above.

Here, the front piece 16 and the rear piece 17 of the drain pan 3 extend substantially vertically. Reference numeral 18 denotes a tongue member, which has a side-view mountain shape, and whose upper side 19 is inclined obliquely upward and faces the cross flow fan 4. Also, this tongue member 18
The lower side 20 is inclined obliquely downward so as to be connected to the lower side 21 of the drain pan 3. Reference numeral 22 denotes a locking piece provided at a front portion of the tongue member 18, and is inserted into the mounting hole 23 of the rear piece 17 of the drain pan 3. Reference numeral 24 denotes a fixed piece of the tongue member 18, which is a rear piece of the drain pan 3.
It hits 17 and the screw 25 is stopped from the front.

Since the tongue member 18 is formed separately from the drain pan 3, the front piece 16 and the rear piece of the drain pan 3 are located diagonally below the cross flow fan 4 and provided with the tongue of the cross flow fan 4. The piece 17 can be formed in a substantially vertical direction, whereby the depth dimension A of the drain pan 3, that is, the drain water receiving capacity of the drain pan can be increased, and the danger of drain water leakage can be reduced.

As shown in FIG. 3, when the depth dimension B of the heat exchanger 20 is larger than the depth dimension C of the heat exchanger 2 shown in FIG. twenty one
Can be attached to the rear piece 17 of the drain pan 3. Thereby, the gap E between the upper side 22 of the tongue member 21 and the cross flow fan 4 can be reduced, and the performance of the blower can be improved.

(G) Effects of the Invention As described above, in the heat exchange unit that houses the heat exchanger, the drain pan disposed below the heat exchanger, and the cross flow fan disposed above and behind the drain pan. , A lower side connected to a lower side of the drain pan,
It has a tongue-shaped tongue member having a diagonally upward facing side facing the cross flow fan, and since this tongue member is detachably attached to the back of the rear piece of the drain pan, the front piece and the rear piece of the drain pan can be removed. The drain pan can be extended in the vertical direction, thereby making it possible to prevent the drain water from leaking by increasing the depth dimension of the drain pan. Moreover, since the tongue member is formed separately from the drain pan and this tongue member is detachably attached to the rear of the rear piece of the drain pan, if the tongue member is changed according to the size of the cross flow fan and the ventilation resistance. Not only can the drain pan be shared, but also the tongue member having the optimal shape can be selected and used to enhance the air blowing performance, and the tongue member can be reduced to the minimum necessary, which is economical.
