Abstract

PURPOSE:To permit to obtain sufficient capacity upon both of room cooling and heating operations by a method wherein a slinger ring, made of a shape-memory alloy changing the shape thereof in accordance with an atmospheric temperature, is provided at the outer periphery of an outdoor fan. CONSTITUTION:Upon the room cooling operation, the condensed water, generated in an indoor heat exchanger 7, is reserved in a base plate 8 through a drain pipe 10 and is splashed to an outdoor heat exchanger 4 by the slinger ring 2 of shape-memory alloy, which is being rotated together with the outdoor fan 1, whereby the capacity of a condenser is increased. Upon the room heating operation, the slinger rings 2 is brought into the deformation condition of low temperature side and is bent to the inside thereof as shown by arrow signs. Accordingly, the condensed water, generated in the outdoor heat exchanger 4, is not splashed to the outdoor heat exchanger 4 by the slinger ring 2, therefore, the capacity of an evaporator will never be decreased and, further, evaporating temperature in the evaporator will never be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a condensate 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 that splashes condensed water is provided in the part, and this slinger ring 2
The condensed water was splashed onto the condenser to increase the condensing capacity.

However, with this configuration, during cooling operation, the heat exchanger outside room 2 becomes the condenser side, so condensed water is splashed and the condensation capacity increases, but during heating operation, the condensation capacity increases. Conversely, since the outdoor heat exchanger becomes an evaporator, the evaporation capacity is reduced due to condensed water being splashed7, and the evaporation temperature of the evaporator also decreases, causing the condensed water to form frost on the heat exchanger. There was a case.

OBJECTS OF THE INVENTION The present invention is intended to solve the above problems, and aims to provide sufficient performance 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 air temperature around the outer periphery of an outdoor fan.

With this configuration, during cooling, condensed water is used for heat exchange,
During heating, contact between condensed water and the slinger ring can be prevented.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 3 of the accompanying drawings.
- This will be explained with reference to Figure 4.

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. Slinger ring 2. Outdoor heat exchanger4. It has an indoor heat exchanger 7, etc. A slinger ring 2 made of 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, 6 is a motor, 6 is an indoor fan, 8 is a board, 9 is a compressor, and 10 is a drain pipe.

FIG. 2 shows the shape of the slinger ring 2 and the state in which condensed water is splashed during cooling operation. The condensed water generated in the indoor heat exchanger 7 passes through the drain pipe 10 and accumulates in the board 8, and the slinger ring 2 rotates together with the outdoor fan 1.
It is splashed onto the outdoor heat exchanger 4 and evaporated, increasing the 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, frosting of the condensed water on the outdoor heat exchanger 4 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 slinger ring made of a shape memory alloy that changes its shape on the outdoor fan, and because the condensed water is scattered only during cooling operation, the improvement in both cooling and heating capabilities is not achieved. Furthermore, since the slinger ring undergoes a rapid shape change at the transformation temperature, it has good responsiveness similar to a thermistor, etc., and secondly, it changes depending on the outside temperature, so it does not require a complicated control device. It has various advantages such as.
