状の機外連結管12aに生じる結露水を捕集する。Generally, when the air conditioner and the air outlet are connected by a long duct, or when the air outlet having a large ventilation resistance is used, a model having a large external static pressure that withstands a high pressure loss is used as the air conditioner. As this type of air conditioner having a large external static pressure, a floor-mounted type shown in FIG. 6 is conventionally known (Japanese Utility Model Publication No. 62-85818). In this air conditioner, the heat exchanger is placed in the case 11 by facing the air outlet 15 on the upper surface of the case.
A fan 14 for storing 12 and partitioning the inside of the case 11 into upper and lower parts is attached to a lower surface of a fan mounting plate 13 for pumping air sucked through a filter 17 from a suction port 16 at a lower part of the case at a relatively high pressure. . Above the fan mounting plate 13 below the heat exchanger 12, the upstream end 18
a and the downstream end 18b are respectively projected from the case side walls 11 and 11r (see FIG. 7) to fix the drain pan 18, and
A partition plate 19 extending in the longitudinal direction of the case closes the space between the lower edge of the heat exchanger 12 and the case front wall 11f. Thus, the static pressures on the upstream side and the downstream side of the heat exchanger 12 are set to 8 mmAq and 5 mmA, respectively.
While being held at q, water droplets that condense on the heat exchanger 12 and fall are collected by the drain pan 18 and discharged from the discharge port 20 of the downstream end 18b to the outside of the machine. The case side wall
The upstream end 18a of the drain pan 18 protruding from 11 collects the condensed water generated in the U-shaped external connecting pipe 12a.

ることにある。However, the above conventional air conditioner is a model with a large external static pressure, and since the static pressure on the upstream side of the heat exchanger 12 is kept relatively high at 8 mmAq, the condensed water accumulated in the drain pan 18 , Is pushed to both ends 18a, 18b open to the atmosphere and spouts from the gap between the case side walls 11, 11r and the drain pan bottom 18c, especially at the upstream end 18a where the drain pan is shallow, as shown in Figs. 7 and 8. However, there is a drawback in that the condensed water that has been pushed up overflows over the drain pan wall. Therefore, an object of the present invention is to prevent the dew condensation water from spouting or overflowing from the drain pan even if the model has a large external static pressure by devising the structure of the drain pan portion, so that the dew condensation water can be discharged smoothly. It is to provide an air conditioner that can.

きる。Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. FIG. 1 is a sectional view showing a main part of an example of an air conditioner of the present invention. In this air conditioner, the partition plate 2 is provided between the lower edge of the heat exchanger 12, that is, the lower edge of the partition plate 19 and the bottom 18c of the drain pan 18.
The drain pan 18 is divided into a high pressure portion 3 and a low pressure portion 4 by partitioning the case 1 along the entire length in the longitudinal direction by (see FIG. 3). Further, as shown in FIG. 2, both end portions 18a and 18b of the drain pan 18 are projected outward from both side walls 1 and 1r of the case 1 and are condensed from the outside connecting pipe 12a at the upstream end portion 18a. While receiving water (see Fig. 4),
Of the end portions 18a, 18b, the lid portion 5 provided on the case 1 of the high voltage portion 3
While closing with l and 5r, the low pressure part 4 has an opening 6 provided in the case 1.
It is opened by l and 6r (see Figs. 4 and 5). The rest of the configuration of the air conditioner is the same as the conventional one described in FIG. The function of the drain pan of the air conditioner configured as described above is as follows. On the high-pressure section 3 side of the drain pan 18 partitioned by the partition plate 2, water droplets mainly condensed on the heat exchanger 12 in the case 1 fall and collect. Condensation water collected on the side of the high pressure part 3 should be washed away and concentrated on both ends 18a, 18b because both ends 18a, 18b of the high pressure part 3 are blocked by the lids 5l, 5r of the case 1, respectively. Moreover, it does not spout out of the case 1 and overflow beyond the wall of the shallow upstream end 18a of the drain pan (see FIG. 4). That is, the inside of the high pressure section 3 is uniformly high pressure (for example,
8 mmAq), the condensed water that has accumulated flows down the drain pan 18 toward the lower downstream end 18b, part of which exudes from the slight gap at the lower edge of the partition plate 2 toward the low-pressure part 4 and part of it As shown in Fig. 5, it exudes outward from a slight gap at the lower end of the lid 5r. On the other hand, on the low pressure part 4 side of the drain pan 18 partitioned by the partition plate 2, the condensed water falling from the external connecting pipe 12a of the heat exchanger 12 flows into the low pressure part 4 as shown in FIG. Four
Since both ends 18a, 18b of the are open to the atmosphere through the openings 6l, 6r, they will not be affected by high pressure and will merge with the above-mentioned condensed water on the high pressure side that exudes from the lower edge of the partition plate 2. hand,
The drain pan 18 flows down toward the downstream end 18b, and is discharged out of the machine through the discharge port 20 of the downstream end 18b as shown in FIG. As described above, according to the present invention, the drain pan of the condensed water generated in the heat exchanger 12 even in the air conditioner having a large external static pressure.
It is possible to reliably prevent the jet from 18 and the overflow to the outside, and it is possible to smoothly discharge the condensed water from the discharge port 20 at the downstream end.

The lower edge of the heat exchanger and the bottom of the drain pan are partitioned by a partition plate over the entire length in the longitudinal direction of the case, dividing the inside of the drain pan into a high pressure part and a low pressure part, and projecting outward from both side walls of the case. Of the two ends of the drain pan, the high pressure part is closed by the case lid, while the low pressure part is opened by the case opening. It is possible to reliably prevent the overflow of water to the drainage water and smoothly discharge the condensed water from the downstream end portion of the drain pan.
