Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to an air conditioner in which drain water accumulated in a drain pan inside the machine is scraped up into a condenser using a rotating plate.

(b) Conventional technology Conventionally, an air conditioner such as that shown in Japanese Utility Model Application Laid-open No. 53-42458 has been proposed as an air conditioner that scrapes drain water accumulated in a drain pan inside an aircraft into a condenser. .

According to this content, the drain pan has a condenser,
A rotary plate for scraping up drain water was provided in the condenser, and a drain outlet was provided at a constant height on the outer periphery of the drain pan.

The drain water collected in the drain pan is then scraped up by a rotating plate and sprayed onto the condenser, where it is evaporated. However, if more than a certain amount of drain water accumulates in the drain pan due to unevaporated drain water or rainwater, the excess drain water is drained out of the machine from the drain outlet.

(c) Problems to be solved by the invention In such an air conditioner, when the rotating plate rotates, the water level in the rotating direction of the rotating plate becomes higher than the water level in the counter-rotating direction. If the water level in the rotational direction attempts to exceed a certain level, there is a risk that the drain water may be discharged from the drain port to the outside of the machine even if the drain pan does not contain more than a predetermined amount of drain water.

The object of the present invention is to ensure that a predetermined amount of drain water is stored in a drain pan equipped with a rotating plate that scoops up drain water.

(d) Means for solving the problem In order to achieve this object, the present invention provides the drain pan with an upright piece that surrounds the rotary plate and has a water outlet in the counter-rotation direction of the rotary plate, This piece divides the inside of the drain pan into a watering part where a rotary plate is located and a water reservoir part, and a drain port is provided on the outer wall of the drain pan in the water reservoir part at approximately the same height as the height of the rising piece. be.

(e) Function The rotation of the rotary plate scrapes up the drain water in the sprinkler section and sprays it onto the condenser, and even if the water level of the drain water in the sprinkler section rises due to the rising piece, the water level does not rise in the water reservoir section. A predetermined amount of drain water is stored in this drain pan.

The rotary plate 25 is supported by the partition piece 3 of the rotary plate 2, passes below the condenser 4, and supports a rotary plate 25 on the outside of the condenser 4. A rising piece 28 is formed on the bottom plate 27 so as to surround the lower part of the outdoor cross flow fan 5, and this rising piece 28 is connected to the partition piece 3 running diagonally above, and a trailing edge 42 (FIG. 3) is formed on the bottom plate 27. ), the partition piece 3, and the rising piece 28 form a drain pan 29. This drain pan 29
A condenser 4 and a rotary plate 25 are installed, while
Drain water dripped from the evaporator 13 flows into the drain receiver 14, the drain guide 15, and the fin 18 of the condenser 4.
guided through. Most of the drain water from the evaporator 13 flows into the condenser 4 before flowing into the drain pan.
The drain water that is not completely evaporated is received by the drain pan 29 of the bottom plate 27. When drain water accumulates in the drain pan 29 in this way, the rotary plate 25 is rotated in the direction of the dashed arrow in FIG. 4, and the drain water scraped up by this rotation is sprayed onto the condenser 4.

FIG. 5 is a plan view of the bottom plate 27, and 30 is a rising piece provided in the drain pan 29, and this rising piece extends from near the center of the rear edge 42 of the bottom plate 27 to surround the rotary plate 25. ing. Then, by this rising piece 30, the drain pan 29
The interior is divided into a water sprinkling section 31 where the rotating plate 25 is located and a water reservoir section 32 where the condenser 4 is located. Reference numeral 33 denotes a water outlet formed by cutting out a portion of this rising piece 30, which connects the water sprinkling section 31 and the water reservoir section 32. This water outlet 33 is provided in the counter-rotational direction of the rotary plate 25. 34 is a drainage port provided at the rear edge 28.

In this way, the guide pieces 35 and 38 are in contact with the long piece 37 and the short piece 39 of the rising piece 30, respectively, and surround the rotating plate 25.
The upper part is open. Further, the drain port 34 is formed at a position approximately at the same height as the long piece 37.

In the integrated air conditioner with such a configuration, when the rotary plate 25 rotates in the direction of the broken line arrow in FIG. It will be done. When the drain water in the water sprinkling section 31 decreases in this way, the drain water in the water receiving section 32 flows through the water outlet 33. At this time, the rotation direction 40 of the rotary plate 25
The water level is higher than the water level in the counter-rotation direction 41 of the rotating plate 25, and the water surface in the water spraying section 31 is undulating (see FIG. 5). Even if the water level in the water sprinkling part 31 rises and the water surface in this part ripples, the water sprinkling part 31 is separated from the water reservoir part 32 by the rising piece 30 and the guide pieces 35 and 38. Therefore, the water level of the drain water in the water reservoir part 32 is kept lower than the water level of the drain water in the water sprinkling part 31, and there is little possibility that the drain water will drip from the drain port 34. Of course, when the rotation of the rotary plate 25 is stopped, the water level of the drain water in the water sprinkling part 31 and the water level of the drain water in the water reservoir part 32 are maintained in equilibrium through the water outlet 33. At this time, if the water level of the drain water is about to become higher than the height of the drain port 34, the drain water is discharged from the drain port 34 to the outside of the machine.

(g) Effects of the invention As described above, the invention divides the interior of the drain pan into a water sprinkling area where a rotating plate is located and a water reservoir area where drain water is stored, by means of an upright piece. A water outlet is provided in the direction of rotation, and a drainage outlet for drain water is provided on the outer wall of the water reservoir section at approximately the same height as the height of the rising piece. Even if the water level rises or becomes undulating, a predetermined amount of drain water can be stored in the drain pan while reducing the risk of drain water flowing out from the drain port. In addition, when the rotating plate is stopped, if a certain amount of drain water accumulates in the drain pan, drain the excess drain water out of the machine from the drain outlet to prevent parts inside the machine from being soaked in the drain water. It can be reduced.
