Description

[Detailed description of the invention] Industrial application field The present invention relates to a window-mounted heat pump type air conditioner, and in particular facilitates the removal of condensed water that forms on the outdoor heat exchanger during heating operation. It is something.

Conventional configuration and its problems In window-mounted heat pump air conditioners, condensation water that forms on the surface of the fins of the outdoor heat exchanger, which acts as an evaporator, is transferred to the outside air at a low temperature. Furthermore, since the refrigerant at a low temperature is flowing inside the pipes of the outdoor heat exchanger, if it is not removed easily, it will freeze on the surface of the outdoor heat exchanger, and sometimes the outdoor heat exchanger will freeze. When the gap between the heat exchanger and the air conditioner board freezes, the gap is filled with ice, and newly formed condensed ice cannot flow into the board, instead flowing out of the air conditioner instead of through the drainage holes. There were drawbacks such as the occurrence of such problems. Such a conventional heat pump type air conditioner will be explained with reference to FIG. 4.

In FIG. 4, the air guide 4 is placed on the board 41.
2 into an indoor side and an outdoor side, and an outdoor heat exchanger 43 is provided on the outdoor side, and a compressor 44 and an indoor heat exchanger 45 are provided on the indoor side.

In such a configuration, when the air conditioner is operated for heating, condensed water on the outdoor heat exchanger 43 freezes on the surface of the outdoor heat exchanger 43, and the ice grows and damages the substrate 41 and the outdoor heat exchanger. Prevent gap A of 43,
There were cases where newly generated condensed water flowed out to the substrate 41.

Purpose of the invention The present invention is intended to solve these problems, and allows condensed water to easily flow over the surface of the outdoor heat exchanger, be quickly contained in the board, and be drained. The purpose of this is to prevent the problem of condensed water forming in the gap between the air conditioner and the outdoor heat exchanger and flowing out of the air conditioner.

Structure of the Invention In order to achieve this objective, the present invention has a partially cut out lower part of the outdoor heat exchanger fin.

This notch reduces the ventilation resistance inside the outdoor heat exchanger and increases the passing air velocity.
Since the condensed water flows smoothly along the end face of the notch, the condensed water does not freeze on the surface of the outdoor heat exchanger.

Furthermore, since the gap between the board and the outdoor heat exchanger is widened, even if it freezes, problems such as condensed water flowing out to the outside of the board will not occur.

DESCRIPTION OF EMBODIMENTS A window-hung air conditioner according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings.

Reference numeral 1 denotes the air conditioner main body, which has an inlet 2 and an outlet 3 on the front side (indoor side), and an inlet 4 and outlet 5 on the back side (outdoor side).
are provided for each. Inside the air conditioner main body 1, an indoor ventilation passage 7 and an outdoor ventilation passage 8 are formed by an air guider 6, and an indoor heat exchanger 9 and an indoor blower 10 are arranged in the indoor ventilation passage 7. An outdoor heat exchanger 11 and an outdoor blower 12 are disposed in the outdoor ventilation passage 8 . As shown in FIG. 3, the fins of the outdoor heat exchanger 11 have a notch B formed on the lower back surface. This notch B allows a sufficiently large gap C between the fin and the rear edge of the substrate 16. In addition, the partition plate 13 allows
A compressor chamber 15 in which a compressor 14 is housed is formed.

In the above configuration, when the air conditioner is operated for heating, the outdoor heat exchanger 1 acting as an evaporator
The condensed water generated in step 1 smoothly flows along the end face of the fin in the notch B and is stored in the substrate 16. In addition, the notch B does not freeze because the ventilation resistance decreases and the passing wind speed increases. Even if it freezes, the gap C between the substrate 16 and the outdoor heat exchanger 11 is wide, so ice prevents the gap C and condensed water does not flow out of the substrate 16.

Effects of the invention According to the window-mounted air conditioner of the invention, the lower part of the fins of the outdoor heat exchanger is partially cut out, which reduces the ventilation resistance inside the outdoor heat exchanger and increases the passing wind speed. In addition, since the condensed water flows smoothly along the end face of the notch of the fin, the condensed water does not freeze on the surface of the outdoor heat exchanger, and the gap between the board and the outdoor heat exchanger becomes wider. Even if the substrate freezes, problems such as condensed water flowing out to the outside of the substrate will not occur.
