Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a condensate water treatment device for an air conditioner.

Conventional configuration and its problems Conventionally, an air conditioner has a configuration in which condensed water generated in an evaporator is splashed onto the condenser by an outdoor fan, and as shown in FIG. A slinger ring 2 for splashing condensed water is provided on the outer periphery of the condenser, and the slinger ring 2 splashes condensed water onto the condenser to increase the condensing capacity.

However, with this configuration, during cooling operation, the outdoor heat exchanger becomes the condenser side, so condensed water is splashed and the condensing capacity increases, but during heating operation, on the contrary, the outdoor heat exchanger becomes the condenser side. Since the heat exchanger functions as an evaporator, the evaporation capacity is reduced by splashing of condensed water, and the evaporation temperature of the evaporator is also lowered, resulting in condensed water sometimes forming frost on the heat exchanger.

Purpose of the invention The present invention solves these problems.
The purpose is to provide sufficient capacity during both cooling and heating operations.

Structure of the Invention In order to achieve this object, the present invention provides a slinger ring made of a shape memory alloy whose shape changes depending on the outside temperature on the outer periphery of an outdoor fan.

With this configuration, it is possible to use the condensed water for heat exchange during cooling, and to prevent the condensed water from coming into contact with the slinger ring during heating.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4 of the accompanying drawings.

First, the schematic structure of a window type air conditioner will be explained with reference to FIG.

In the figure, the air conditioner includes an outdoor fan 1, a slinger ring 2, an outdoor heat exchanger 4, an indoor heat exchanger 7, and the like. A slinger ring 2 made of a shape memory alloy is attached to the outer periphery of the outdoor fan 1 for each blade of the outdoor fan 1. In addition,
3 is an air guider, 5 is a motor, 6 is an indoor fan,
8 is a substrate, 9 is a compressor, and 10 is a drain pipe.

Figure 2 shows slinger ring 2 during cooling operation.
The figure shows the shape of and the state of condensed water splashing. Condensed water generated in the indoor heat exchanger 7 passes through the drain pipe 10 and accumulates in the board 8, and is splashed onto the outdoor heat exchanger 4 by the slinger ring 2 rotating with the outdoor fan 1, where it evaporates. and increase condenser capacity.

Figure 4 is a diagram showing the characteristics of shape memory alloys.As is well known, deformation occurs at the transformation temperature t, that is, a shape change occurs, and the property is that the shape is restored to the memorized shape on both the low temperature side and the high temperature side. have.

FIG. 3 shows the shape of the slinger ring 2 during heating operation. During heating operation, the slinger ring 2 is deformed to the low temperature side and bends inward as shown by the arrow.

Therefore, since the condensed water generated in the outdoor heat exchanger 4 is not splashed onto the outdoor heat exchanger 4 by the slinger ring 2, the evaporator capacity does not decrease, and furthermore, the evaporation temperature of the evaporator does not fall. Therefore, frost formation on the outdoor heat exchanger 4 of condensed water is less likely to occur. In addition, since a sudden change in shape occurs at the transformation temperature, it has good responsiveness similar to a thermistor or the like, and does not require a complicated control device.

Effects of the Invention The condensed water treatment device of the present invention is equipped with a shape-memory alloy slinger ring that changes its shape on the outdoor fan, and since condensed water is scattered only during cooling operation, the improvement in both cooling and heating capabilities is lost. Furthermore, slinger rings have various advantages, such as rapid shape changes that occur at the transformation temperature, so they have good responsiveness similar to thermistors, and they do not require complicated control devices because they change depending on the outside temperature. It is something.
