Abstract

PURPOSE:To improve silent atmosphere under a low load in an air conditioner in which a rate of heat exchanger is improved by a slinger ring by a method wherein a flow rate control device for blocking condensed water of an evaporator is formed by a shape memory alloy material having deformation amount stored in it so as to close the opening when the surrounding atmosphere is less than the desired temperature. CONSTITUTION:Condensed water adhered to an evaporator 3 is passed through a drain hose 12 and flowed to an air guiding means 9. During a cooling operation, when the surrounding temperature is low and the load is low, the flow rate control device 10 becomes a condition where a door 10b is closed. That is, the driving plate 10a formed by the shape memory alloy is returned to its original shape due to the fact that the outdoor temperature is kept at a low temperature less than the transformation temperature. Therefore, the opening 9a of the air guide 9 is closed, the flow of the condensed water toward the condensor 4 is clogged. Since the condensed water is not flowed out of the room and to the fan 6, noise caused by the dispersion of the condensed water by the slinger ring 6a is prevented and a silent operation can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is an air conditioner in which the heat exchange rate is improved by slingering. The present invention relates to a condensed water treatment device that controls the flow rate to a heat radiation heat exchanger (hereinafter referred to as a condenser).

Conventional configuration and points of interest Conventionally, integrated air conditioners have improved the performance of the condenser by scattering condensed water generated during cooling operation into the condenser using a slinger ring installed on the outdoor fan. There used to be.

However, in such a structure, condensed water is always scattered by slingering, regardless of when the condenser requires capacity under high load or when the condenser does not require capacity under low load. Therefore, under low loads, the noise caused by unnecessary splashing of condensed water is large, resulting in a lack of quietness.

OBJECTS OF THE INVENTION The present invention aims to eliminate the drawbacks of the above-mentioned three steps, and aims to improve the quietness.

Composition of the Invention The present invention houses a board on which a compressor, a condenser, an evaporator, and an outdoor fan for cooling the condenser are mounted in an air conditioner main body, and further includes a water tray in the evaporator. A drain hose is provided on the water tray to guide the condensed water of the evaporator below the outdoor fan, and a slinger ring is provided on the outer periphery of the outdoor fan to scatter the condensed water to the condenser. an air guider for the outdoor side fan; a flow rate control device for damming condensed water from the drain hose; a door that opens and closes the opening; a drive plate that opens and closes the door; and a seal plate that is provided on the door and seals the door and the opening; is characterized by being formed from a shape-memory material that stores the amount of deformation so that the door opens when the surrounding temperature reaches a set temperature or higher and closes when the temperature falls below the set temperature.

According to the above configuration, when the outside air temperature is high, the door is opened by the driving plate and the condensed water is used to promote heat exchange, and when the outside air temperature is low, the door is closed by the driving plate, This prevents the condensed water from flowing to the condenser side, thereby preventing the occurrence of flta failure of the condensed water.

Description of examples An embodiment of the present invention will be described below.

FIG. 1 is a longitudinal sectional view of an integrated air conditioner (hereinafter simply referred to as an integrated air conditioner) equipped with the condensed water treatment device of the present invention, and FIG. 2 is a plan sectional view of the integrated air conditioner. Figure 3 is a perspective view of the flow rate control device in the same type air conditioner;
Not shown.

In the figure, (I) is an outer box of an integrated air conditioner, the main body of the air conditioner, and a board (2) is housed inside the main body (1). On this board (2) are installed an evaporator (3), a condenser (4), a fan motor (an indoor fan (5) driven by force, and a slinger ring (6a)) that constitute a well-known refrigeration cycle. an outdoor fan (6) having
Furthermore, a compressor (8) is provided. (9) is the substrate (
2) is an outdoor air guider welded and fixed to the air guider, a part of which is provided with an opening (9a,), and a flow rate control device (1o) that controls the flow rate of condensed water to the condenser side is installed in this opening (9a). It is provided. (13) is a water receiver for receiving condensed water from the evaporator (3), and is provided with a drain hose (I2) that guides the condensed water to the front side of the air guider (9). Reference numeral 01) is a water level adjustment pipe that is provided to protrude from the substrate (2) at a certain height and adjusts the water level of condensed water.

Next, according to FIG. 3, the condensed water flow rate control device 00) of the present invention
The configuration of is explained below.

(10a) is a drive plate that drives the opening and closing of the door (10b);
It is fixed to the air guider (9). This drive plate (10
A) is formed from a well-known shape memory material whose shape on the high temperature side above the transformation temperature is memorized. (1oc)
Is the opening (9a) closed when the opening (9a) is closed?
−? It is attached to the door (1, ob) with a seal of J).

Here, the shape memory alloy of the drive plate (10a) is a shape memory alloy whose transformation temperature is the boundary temperature between the outdoor temperature range of high load and low load, and its characteristics are as shown in Figure 6. It has some hysteresis. And the drive plate (1
0a) opens the door (101) as shown in Figure 4 when the outdoor temperature is likely to cause a high load on the refrigeration cycle, and opens the door (101)) as shown in Figure 5 when the outdoor temperature does not easily cause a high load on the refrigeration cycle. It acts to close the door (1, ob) as shown in .

Next, the flow of condensed water will be explained.

Condensed moisture in the indoor air that reaches the evaporator is collected in a water tray. This condensed water flows through the drain hose (12) to the air guider (9) side. During cooling operation, when the outside air temperature is high and the refrigeration cycle is under high load or is likely to be under high load, the door (xob) of the flow control device 00) is in an open state as shown in FIG. That is, the driving plate (IOa) deforms into the memorized shape because the outdoor temperature is in a high temperature range that is higher than the transformation humidity. Therefore, the opening (9a) of the air guider (9) is opened, and the condensed water flows toward the condenser and is scattered to the condenser (4) by the slinger ring (6a) K of the outdoor fan (6).

Thereby, the condenser (4) is cooled and its capacity is improved.

In addition, during cooling operation, when the outside air temperature is low and the load is low, the flow rate control device OQ is activated as shown in Figure 5.
0b) is in a closed state. That is, the drive plate (10a)
returns to its original shape because the outdoor humidity is in the low temperature range below the transformation temperature. Therefore, the opening (9a) of the air guider (9)
) is closed, and the flow of condensed water toward the condenser (4) is blocked. In this state, when the water level of condensed water exceeds the set water level, it is drained out of the air conditioner through the drain port αυ. Therefore, at low load times when splashing of condensed water is unnecessary, the condensed water does not flow toward the outdoor fan (6), which prevents noise caused by splashing of condensed water and improves quiet operation.

Effects of the Invention As described above, the present invention compensates for the lack of condensing capacity during high loads during cooling operation by using the scattering action of condensed water. Since the splashing effect of water is stopped, the noise that conventionally occurs continuously regardless of whether the load is low or high can be eliminated, resulting in improved silence. Furthermore, since the door that controls the flow rate of condensed water is operated by a drive plate made of a shape memory alloy, manual operation is not required, resulting in improved usability.
