Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an integrated air conditioner in which a compressor, a condenser, an evaporator, etc. are housed in a single box to form a unit.

Conventional Structure and Problems Conventionally, this type of integrated air conditioner has been structured as shown in FIGS. 1 and 2. In other words, in the same figure), when the integrated air A is placed on the board, the indoor f is placed on the board.
The main body is composed of a partition wall e that separates the il1 ventilation system path C and the outdoor ventilation system path d, an outer box f, and the like. The outdoor side ventilation system path d has an outdoor side 7/1 exchanger facing the back side qrlrc, and the motor 1 is installed on the bulkhead e so that its axis of rotation is perpendicular to the bulkhead e, r=1. I'm being kicked. J is a propeller fan attached to one end of this motor l that blows air toward the outdoor heat exchanger. It has a link p. K is a compressor that constitutes a well-known refrigeration cycle together with the outdoor heat exchanger. Further, an indoor heat exchanger m is attached to the front side l of the indoor ventilation system path C. Indoor heat exchanger m(!: multi-blade fan arranged in rows, attached to the other end of motor i, blowing air passing through indoor heat exchanger m into wind tunnel n.

Here, it goes without saying that the ideal ventilation path in this type of integrated air conditioner has a lower resistance, the better. The following conditions are required: the front area (hereinafter referred to as the front surface area) is wide, the depth through which the wind passes (hereinafter referred to as the number of rows) is short, and the ventilation path is wide and smooth with few bends.

Only when these conditions are met will a ventilation system path with low ventilation resistance be constructed, and the realization of an integrated air conditioner that can blow a large wind mass with low noise using a small-capacity motor will become a +iJ function. .

However, conventional integrated air conditioners of this type are installed through walls or through windows, so
The front area was made as small as possible in order to avoid the need to make large holes in the wall and to avoid significantly impairing the natural light provided by the windows.

In addition, conventional air conditioners of this type were made smaller to reduce costs, as shown in Figure 1.

As shown in Fig. 2, we focused on simultaneously driving the multi-blade fan 0 on the indoor side and the propeller fan on the outdoor side with one motor 1, so the +
iiJTherefore, it is necessary to arrange an indoor heat exchanger m and an outdoor heat exchanger 1 along the front and rear sides q, respectively, and therefore, it is necessary to arrange the indoor and outdoor heat exchangers m and h to ventilate the The outdoor ventilation system path C9d was a narrow and curved yarn path.

Because of B, a considerably large motor L is required for ventilation, and the front area of each heat exchanger (11!! m, h) has to be small, so
It became necessary to increase the depth dimension by increasing the number of stages of h, and the cost of both the motor l and the heat exchangers m and h increased. This results in the opposite of the original purpose of making the fan motor 1 cheaper, and it cannot be said to be a good ventilation structure at all.

That is, as mentioned above, two fans 0. Since priority is given to the form in which J is attached, the multi-blade fan 0° propeller fan J's suction side and outlet 11! It was not possible to make the shape of 1 such that these fans 0+] could be operated with low noise. Since the puckering ring p faces almost perpendicularly to the horizontal button in the board, its ability to scoop up condensed water is small, and at the same time, the water scooping efficiency is poor, and it does not contribute much to improving the performance of the heat exchanger. It was nothing. Furthermore, large water droplets fly off when the water is stirred up, causing problems such as the generation of loud noise.

As mentioned above, the conventional structure 1171 inevitably generates a lot of noise, requires a dog-friendly motor, and cannot efficiently treat condensed water from the indoor heat exchanger. was there.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and improves ventilation efficiency to reduce noise, and increases the degree of heat exchange utilization of condensed water, thereby improving heat exchange efficiency. The purpose is to

With this configuration, the airflow direction of the ventilation circuit is different from the conventional one, and the ventilation resistance is reduced, and the water splash prevention temporary allows the condensed water splashed by the slinger link to be efficiently removed outdoors (

97.98. The right and left water splash prevention plates 41 and 42 are provided with loops 99 that prevent water splashed from the slinger link 27 from scattering outside the main body and allow air to flow in from outside the main body. There is. This looper 99 is inclined at a constant angle with respect to the outer surface of the outdoor heat exchanger 26.

In the above configuration, the flow of air when the fan motor 3Q is operated will be explained. First, when the fan motor 30 is operated by operating the electric component operation knob 57, the vignetting blackbell fan 2 is attached to both ends of the shaft of the fan motor 3o.
8, the sirocco fan 61 rotates. As a result, the outdoor ventilation system passage 23 has a suction port 1115 of the outer box 3, a suction port 16 on the left side 11, and
The air sucked in by the right side intake 1117 is 7.
? The air passes through the J compressor 26 at a substantially uniform speed, passes through the air guider 31 by the propeller fan 28, and is air-flowed to the top side air outlet 20, the left side air outlet 18, and the right side air outlet 18.
It started blowing up from 19. Also indoors (ni1 ventilation system path 2
4 and C”: As shown by the arrows in Figures 7 and 8, 1) 11
The air sucked in from the suction port 6 of the side grill 2 is sent to the evaporator 3.
6 and through suction r-153 to solonocofan 5
1 to the duct 56, and the air from the front creel 2 [
-] Sent into the room from 7.

Next, by operating the electrical component operation knob 57, the compression i.
When the is operated, the high-temperature gaseous refrigerant sent from the compressor 38 to the discharge pipe 33 is sent to the condenser 26, where it is efficiently cooled by the air flowing uniformly through the pseudo-condenser 26 and becomes a high-temperature liquid refrigerant. -34 and pass through the capillary tube. During that time, a low-pressure gas-liquid mixture state is created.
It reaches the evaporator 36. In the evaporator 36, the gas-liquid mixed refrigerant is given heat by the wind passing through the evaporator 36, becomes gaseous, and since the heat insulating strips 4-r, 4.8, and 49 are wound, the heat blown by the propeller fan 28 is absorbed. The suction pipe 37 and the accumulator 49 of the compressor 38 are separated by 1 m to be sucked into the compressor 38 again.

When the compressor 38 is operated in this manner, the air passing through the evaporator 36 is stripped of heat and moisture. Therefore evaporator 3
Condensed water adheres to the surface of the evaporator 6, and the water reservoir below the evaporator 36 collects in the tray 50, and is guided to the side of the ventilation thread 23 of the chamber 111 of the substrate 22.

The condensed water accumulated on the substrate 22 is removed by the slinger link 27 of the propeller fan 28.

The water attached to the slinger ring 27 is scattered in the circumferential direction of the slinger ring 2, hits the left bent part 81 and the right bent part 82 of the condenser 26, and passes through the left bent part 81 and the right bent part 82. It jumps out of the condenser 26. However, the left bent part 81 and the right bent part 82 facing the left side suction port 16 and the right side suction [117] of the outer box 3
A left wood rust prevention plate 41 and a right wood rust prevention plate 42 are provided at the top of the water escape line of the sludge ring 27, and since the splashed water hits these, the water flows out through the condenser 26. It will be prevented. In addition, left and right water splash prevention plates 4
1.42 is equipped with a looper 99 that allows air to pass through, so the left and right water splash prevention plates 4 are passed through this looper 99.
Air from outside also passes through the outdoor heat exchanger 26 portion that is blocked at 1.42. In addition, some of the water scraped up by the slinger ring 27 is turned into small droplets and blows out on the wind toward the bulkhead 254Ell through the condenser 26. Head toward the left side air outlet 18 and the right side air outlet 19. At this time, since the small water droplets hit the looper-shaped wind direction changing plate 69, they do not fly out to the outside of the outer box 3.

In addition, the hot air and small water droplets passing through the compressor 26 and heading towards the 25 bulkheads are blocked by the sealing material 77, 78, 79, 80 between the bulkhead 25 and the outer box 3, and are blocked by the indoor ventilation system path 24. Do not invade.

Also, sealing materials 74 and 75 are pasted on the inside of the outer box.

76 prevents the wind passing through the air guider 31 from short-circuiting through the gap in the outer box 3 and being sucked into the suction [116] on the back surface 9 and the left and right suction ports 16.17 on the left and right side surfaces 10.11.

Such an integrated air conditioner provides the following effects.

(1) The wind passing through the condenser 26 is
Since the air flows smoothly without being disturbed according to the intake action of the propeller fan 28, the condenser can be made smaller compared to the conventional case where the condenser is disposed on the outlet side of the propeller fan 28, reducing noise. Since the air is taken in from the ill, a large intake area can be obtained, and the heat exchange performance of the condenser 26 can be improved.

(2) Also, the air passing through the condenser 26 and blown out from the propeller fan 28 is transmitted to the top surface 12 of the outer box 3 and both left and right side surfaces 10.
Since the air flows smoothly toward the air outlets 18, 19 and 20 of 11, there is less ventilation resistance in the ventilation system path on the outdoor side, so the input to the motor 30 can be small. In addition, since the wind flow is 11′1- smooth toward the outer box 3, the bulkhead 2
The distance between 5 and the air guider 31 can be made relatively small, and the outdoor ventilation system path can be made compact. However, since the distance between the blower in the ventilation system path on the indoor side and the evaporator 36 can be increased by that amount, the noise of the indoor side blower can be reduced.

(3) The anti-condensation water stirred up by the slinger ring 27 of the propeller fuano 28 directly hits the a dairy 26 and improves the performance of the condenser 26, but the water provided in the part that hits the mineral water line of the slinger link 27 of the a dairy 26 Fly prevention plate 41.
42 prevents the heat exchanger from passing through the heat exchanger and projecting to the outside. In addition, left and right water splash prevention plates 41.42tg-
d. Since an intake looper 99 is provided, air from the outdoor side passes through the louver 99 and also passes through the outdoor heat exchanger section which is blocked by the left and right water splash prevention plates 41 and 42. Therefore, the water that has passed through the outdoor indoor heat exchanger hits the water splash prevention plates 41, 42 and their loopers 99, and does not splash out to the outside. Furthermore, the outdoor heat exchanger portion covered with the water splash prevention plates 41 and 42 can be cooled by both the splashed water and the air, thereby improving the performance of the heat exchanger.

(4) Also, the tip of a part of the condensed water scorched by the slinger link 27 hits the louver-shaped wind direction changing plate 69 whose tip is directed toward the bulkhead 25 side, so that it does not fly out to the outside. Furthermore, when passing through the gap between the bulkhead 25 and the outer box 3 toward the ventilation system on the indoor side, the crystal wind and moisture are blocked by the sealing material 79 provided between the bulkhead 25, the human side of the bulkhead, and the outer box 3. This prevents water from entering the room and reducing cooling capacity due to hot air entering the room. In addition, the suction pipe, compressor accumulator, etc. are insulated to prevent heat absorption from the hot air sent out by the propeller fan 28, so the suction efficiency of the compressor 38 is not reduced, and air cooling is efficiently achieved. Can drive.

Effects of the Invention As is clear from the above embodiments, the present invention has an advantage in that the air passing through the outdoor heat exchanger flows from the opposite side walls of the outer box toward the blowout opening on one side, so that the air intake action of the outdoor fan is improved. Therefore, the noise can be reduced compared to when the outdoor heat exchanger is installed on the outlet side of the outdoor fan as in the past, and the noise can be reduced. Since the air is taken in from the heat exchanger 111.11, the air intake area can be increased, and the heat exchange performance of the outdoor heat exchanger can be improved. In addition, the outdoor heat exchanger is equipped with a water splash prevention plate that prevents water splashed by the slinger link from scattering outside the main body. (It is possible to exchange heat with the 1111 heat exchanger, improving the flocculating ability. Furthermore, since the water splash prevention plate is provided with ventilation holes, the a shrinking ability can be further improved. hole,
By creating a circuit in which the wind flows in a meandering manner, ventilation is reduced to iJ.
This function prevents water from splashing outside the body, resulting in more effective water splash prevention.
