Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an air conditioner that scrapes up drain water inside the machine to a condenser.

(b) Prior Art Conventionally, as an air conditioner that scrapes up drain water inside the machine to a condenser, there has been disclosed an air conditioner as shown in Japanese Utility Model Publication No. 36848/1983.

According to this content, a condenser and a rotary plate for scooping up drain water into the condenser were arranged side by side inside the machine, and the cabinet of the machine was located above the condenser.

The drain water that was scraped up by the rotating plate and hit the cabinet was then guided to the condenser.

(c) Problems that the invention aims to solve In such air conditioners, the part of the cabinet located above the condenser was flat, so the drain water that was scraped up by the rotating plate and hit the cabinet There was a risk that the liquid would travel through the cabinet or be splashed by the cabinet and drip onto the outside of the aircraft.

The purpose of the present invention is to prevent the drain water scraped up by the rotary plate from dripping outside the machine, and to guide this drain water to the condenser.

(d) Means for solving the problem In order to achieve this objective, the present invention includes a fan located inside the exterior body provided with the ventilation grill, and a ventilation grill located on the windward side of the fan. A built-in condenser and a rotary plate located between the exterior body and the condenser to scrape up drain water to the condenser are installed, and a tube plate is provided at the top of the condenser. In this system, an inclined surface is provided to guide the water droplets of drain water scraped up by the rotating plate to the condenser, and the end of this inclined surface is fixed to the exterior body while maintaining storage space for the rotating plate. .

(e) Effect Drain water that is scraped up above the rotating plate by rotation of the rotating plate is made to adhere to the inclined surface of the tube plate at the upper edge of the condenser, and the attached drain water flows along this inclined surface. so that it flows to the condenser side.

(f) Example Figure 1 shows an integrated air conditioner 1 installed in a window.
FIG. Reference numeral 2 denotes a partition plate that partitions the interior of the air conditioner into front and rear parts, and is placed on a rising piece 3 (see FIG. 2) that runs approximately diagonally on the bottom plate. 4 is a condenser, and this condenser is installed so that its fins overlap in the vertical direction. Reference numeral 5 denotes an outdoor cross-flow fan, which sucks air through a ventilation grille 7 of an exterior body 6, exchanges heat with a condenser 4, and then discharges it from a discharge port 8.

9 is a fan casing attached to the front side of the partition plate 2, and 10 is a horizontal partition plate that partitions the front side of the air conditioner into an upper indoor chamber 11 and a lower machine room 12 (see FIG. 2). 13 is an evaporator, 14
A drain receptacle is formed by recessing the horizontal partition plate 10 below the evaporator 13, and is used to receive drain water dripping from the evaporator 13. A drain guide 15 is integrally formed with the drain receiver 14, and this drain guide 15 is connected to the fan casing 9.
The drain guide 15 extends into the outdoor chamber 16 through the partition plate 2 , and the tip 17 of the drain guide 15 is in contact with the fin 18 of the condenser 4 . Reference numeral 19 denotes an indoor cross-flow fan supported by a horizontal plate 10 and a top plate 20 (see Figure 3). The discharge port 22 is guided by the casing 9.
It is discharged from.

FIG. 2 is a cross-sectional view showing the internal structure of the lower part of the air conditioner 1. As shown in FIG. 23 is a compressor that performs a cooling function by sending the refrigerant liquefied by dissipating heat in the condenser 4 to the evaporator 13; 24 is a motor for driving the rotating plate 25; the rotating shaft 26 of this motor is connected to the bottom plate 27;
The rotating plate 25 is supported by the rising edge 3 of the condenser 4 and passes below the condenser 4 to support 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 above-mentioned rising piece 3 running diagonally, and the rear edge 2 is formed on the bottom plate 27.
8 (see FIG. 3) and a drain pan 29 surrounded by the rising pieces 3 and 28 is formed. A condenser 4 and a rotary plate 25 are disposed in the drain pan 29, and the drain water dripped from the evaporator 13 is guided through the drain receiver 14, the drain guide 15, and the fins 18 of the condenser 4. . Before most of the drain water from the evaporator 13 flows into the drain pan,
Although the drain water is heated and evaporated by the heat of the condenser 4, the drain water that is not completely evaporated is received by the drain pan 29 of the bottom plate 27. In this way, drain pan 2
When drain water accumulates in the drain 9, it is scraped up by the rotation of the rotary plate 25 and sprayed onto the condenser 4.

FIG. 5 shows the relationship between the condenser 4 and the exterior body 7. Reference numeral 30 is a ventilation grill formed on the exterior body, which is inclined at approximately 30° toward the rear of the aircraft body. Reference numeral 31 denotes a tube plate attached to the upper end of the condenser 4, which is bent into a substantially U-shape, and the rising piece 32 on the left side of the figure is screwed to the end 33 of the top plate 20. Further, the right rising piece 34 is provided with a vertical surface 35 that is screwed to the exterior body, and an inclined surface 36 that is higher on the exterior body 7 side and lower on the condenser 4 side. The right rising piece 34 is located above the ventilation grille 30.

That is, the inclined surface 36 is provided on the tube plate 31 of the condenser 4, and the end (vertical surface) 35 of this inclined surface 36 on the side of the ventilation grill 30 is connected to the rotating plate 25.
It is fixed to the exterior body 7 with screws while maintaining the storage space (the distance between the ventilation grill 30 and the condenser 4).

Therefore, the water droplets that have been scraped up by the rotary plate 25 and thrown above the rotary plate 25 hit the inclined surface 36 and adhere to this surface. At this time, the water droplets that hit the inclined surface 36 and splashed toward the exterior body 7 are
The water is received by the inner wall 37 of and flows down along this inner wall 37. On the other hand, water droplets adhering to the inclined surface 36 flow down along this surface and are transmitted to the fins of the condenser 4. Here, since the condenser 4 is arranged on the windward side of the cross flow fan 5 (see Fig. 1), the drain water transmitted to the fins is transferred to the cross flow fan 5 side, that is, the anti-ventilation grill 7 by the air flowing between the fins. Flows to the side. In this way, water droplets that hit the inclined surface 36 do not fly out directly from the ventilation grille 30 to the outside of the machine.

(g) Effects of the invention As stated above, the present invention is designed to collect water droplets of drain water scraped up by a rotary plate onto the tube plate at the upper edge of the condenser, which is installed opposite the ventilation grille of the exterior body. Since a sloped surface is provided, the water droplets of drain water are smoothly guided to the condenser through the sloped surface.
Here, since this condenser is arranged on the windward side of the fan, the drain water led to this condenser flows to the fan side within the fins of this condenser. For this reason, even if the rotary plate that scrapes up the drain water is placed opposite the ventilation drain of the exterior body, it is possible to reduce the risk of water droplets of the drain water scraped up by the rotary plate flying out from the ventilation grill. can. Furthermore, when such an air conditioner is installed in a window, it is possible to reduce the possibility that the outdoor side of the window gets wet with water droplets from the drain.

Moreover, by fixing the tube plate of the condenser provided with this inclined surface to the exterior body, the storage space for the rotating plate, that is, the dimension between the condenser and the exterior body can be reliably maintained.
