Description

[Detailed description of the invention] Fig. 1 shows a cross section of an indoor unit of a conventional air conditioner, in which 1 is a heat exchanger, 2 is a heat exchanger, 3 is a heat exchange tube of heat exchangers 1 and 2, 4 is heat exchanger 1, 2
5 is a capillary tube; 6 is a material (hereinafter referred to as damping material) for reducing the sound of the refrigerant flowing inside the capillary tube 5, which is placed around the capillary tube 5; It's wrapped around it. 7 is a drain pan, 8 is a main body casing, 9 is a blower, 10 is a blowing louver, and 20 is an air filter. Indoor air is sucked into the main body casing 8 from the suction grill 13 as shown by arrow 11, dust is removed as it passes through the air filter 20, heat exchanged and cooled as it passes through the heat exchangers 1 and 2, and then the air is cooled by the blower 9. The flow direction is determined by the blow-out louver 10, and the air is blown into the room from the blow-off port 14. When heat exchangers 1 and 2 or either one is used as an evaporator, condensed water generated on the surfaces of heat exchangers 1 and 2 is collected in drain pan 7.

Since the damping material 6 is disposed at the position shown in FIG. The temperature of the material 6 decreases, and moisture in the air condenses here as well, forming dew. The moisture condensed on the portion A falls along the surface of the damping material 6, and drips onto the air filter 20 as shown by the arrow B with excess force.
This condensed water ran through the air filter 20 and leaked to the outside of the indoor unit.

The present invention has been proposed to solve the above-mentioned problems, and one embodiment thereof is shown in FIG.

In FIG. 2, 21 is a front cover, 22 is an air filter, 23 is a heat exchanger, 24 is a blower, 2
5 is a drain pan, 26 is a blowout louver, 27 is a main body casing, 28 is a capillary tube, 29 is a substance for reducing the sound of the refrigerant flowing in the capillary tube 28 (hereinafter referred to as a damping material), and 30 is a damping material. Dew condensed on material 29, 3
2 is a dew guide. The air flow inside the air conditioner is indicated by arrows 31.

When the refrigerant condensed by a condenser (not shown) is throttled and expanded in the capillary tube 28, the temperature of the capillary tube 28 decreases, and the temperature of the damping material 29 also decreases. Moreover, since the indoor air flows as shown by the arrow 31, most of the moisture in the air is condensed in the heat exchanger 23, but a portion of it condenses on the surface of the damping material 29 whose temperature has decreased. The condensed water 30 tries to fall toward the air filter 22, but is caught by the dew guide 32, and the caught dew flows along the dew guide 32 from the lower edge of the dew guide 32 to the heat exchanger 23.
completely collected.

Thus, even if the capillary tube 28 and its damping material 29 are located above the heat exchanger 23, dew condensed on the surface of the damping material 29 can be completely collected. The dew guide 32 also serves as a guide for the air filter 22. If the damping material has manufacturing variations, the air filter 2
2, condensed water can also drain into the drain pan 25.
This prevents water from dripping from the indoor unit without being collected.

Another embodiment of the present invention is shown in FIG. 3, in which 101 is a heat exchanger, 102 is a heat exchanger, 103 is a heat exchange tube, 104 is a capillary tube, and 105 is a capillary tube 104. 106 is a drain pan, 107 is a main body casing, 108 is a blower,
109 is a blowing louver, and 112 is a fin. The upper portions of the fins of the heat exchangers 101 and 102 are covered with a damping material 105 along with the periphery of the capillary tube 104, and are solidified into one body.

In FIG. 3, indoor air is sucked into the heat exchanger 1 through a suction port 111 as shown by an arrow 110.
After heat exchange in 01 and 102, blower 10
The air is energized by the blower 8, the direction of the flow is determined by the blower louver 109, and the air is blown into the room from the blower outlet 112. Heat exchanger 101 when both or one of heat exchangers 101 and 102 is used as an evaporator
The condensed water condensed on the surfaces of and 102 is collected in the drain pan 106.

When the refrigerant is throttled and expanded in the capillary tube 104, the temperature of the refrigerant flowing inside the capillary tube 104 decreases, so moisture in the air condenses on the surrounding surface of the damping material 105 and condenses, but this condensed water is used for heat exchange. It flows down into containers 101 and 102 and is all collected in drain pan 106.

Thus, in the present invention, all the dew condensed on the surface around the damping material of the capillary tube is collected in the drain pan. Furthermore, the flow noise of the refrigerant flowing inside the capillary tube can be reduced as in the conventional case. Furthermore, when either one of the heat exchangers is used as a condenser, the upper part of the fins 112 of the heat exchanger is covered with a damping material, which prevents vibration of the heat exchanger due to the refrigerant gas discharged from the compressor. It can be prevented. Furthermore, when the heat exchanger is divided into two parts, a spacer is required between the two heat exchangers, but the function of the spacer can be substituted by the damping material.

When using both or one of the two heat exchangers as an evaporator, air leaks from the gap at the top of the heat exchangers, but it is best to connect the tops of the fins of the two heat exchangers with damping material. Covering prevents this gap from occurring.

FIG. 4 shows an embodiment in which the present invention is applied to an outdoor unit, where 201 is a heat exchanger, 202 is a heat exchanger, 203 is a heat exchange tube, 204 is a capillary tube, and 205 is a capillary tube 204. 206 is a blower, 207 is a blower motor, 208 is a bell mouth for the blower, 209 is an upper case, 210 is a lower case, and 211 is a heat exchanger fin.

The upper portions of the fins 211 of the heat exchangers 201 and 202 are covered with a damping material 205 and integrated with the capillary tube 204.

In this example as well, the capillary tube is covered with a damping material, so the noise of the refrigerant flowing inside the capillary tube is reduced, and the upper part of the heat exchanger fins is covered with a damping material and integrated. Therefore, when the heat exchanger is used as a condenser, it can be prevented from vibrating due to the refrigerant gas discharged from the compressor. In addition, when the heat exchanger is divided into two parts, the damping material acts as a spacer to maintain the distance between them, and at the same time, the damping material fills the gap between the top of the heat exchanger fins and the upper case. Can be closed to block wind.

Above, the case where the heat exchanger is divided into two was explained in the embodiment, but it goes without saying that the present invention can also be applied to a device having one heat exchanger, and the present invention can be applied to an outdoor unit. In this case, the lower part of the fins of the heat exchanger and the capillary tube may be covered with a damping material and integrated.
