Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an integrated air conditioner that is attached to a window or the like.

Conventional technology Normally, integrated air conditioners are characterized by easy installation by being directly attached to a window or wall hole, but since the front window of the air conditioner is blocked, the amount of daylight is reduced. At the same time, the compressor sound, which is a large sound source in the air conditioner itself, easily penetrates into the room beyond the partition wall within the main body, making it difficult to reduce noise.

Therefore, we have developed an air conditioner that uses a connecting cylinder to improve lighting and sound insulation (Japanese Utility Model Publication No. 1981-81350), and an integrated type that reduces noise by improving the sound insulation of indoor and outdoor partition plates. An air conditioner (Japanese Utility Model Publication No. 60-140835) has been devised.

The air conditioner with improved lighting and sound insulation is shown in Figure 5.
It is constructed as shown in FIG.

In the figure, a main body 101 of the air conditioner is composed of an indoor unit 102, an outdoor unit 103, and a connecting cylinder 104 that connects these units. The indoor unit 102 includes an evaporator 10 in a first housing 102a.
5. An indoor blower 106 is provided facing the evaporator 105, a drain pan 10B is provided below the evaporator 105 to which a drain pipe 107 is connected, and a drain pump 109 is connected to the middle part of the drain pipe 107. . Further, the outdoor unit 103 is provided with an outdoor blower 111 equipped with a condenser 11o1 slinger ring in a second casing 103a facing each other, and a compressor 112 is housed therein.

Indoor and outdoor units formed in this way) 102
, 103 are connected at their upper centers by the connecting cylinder 104. The length of this connecting cylinder 104 is formed into a rectangular cylinder shape, and inside the connecting cylinder 104, there are refrigerant pipes 113 that communicate with the evaporator 105, condenser 110, compressor 112, etc. and constitute a refrigeration cycle, and from the power supply to the room. outside blower 106.111,
Compressor 112, operation panel 11 provided on the indoor unit
4, etc., and the drain pan 10 mentioned above.
8 to the upper part of the condenser 110, and a discharge pipe 107 for dispersing drain water therein is connected. Furthermore, 115
is a partition wall that prevents the air circulating in both units 102 and 103 from entering each other.

Problems to be Solved by the Invention In the above structure, in order to install the air conditioner body 101 on the window 116, the indoor unit 102 is placed on the indoor side of the air-conditioned room, and the connecting cylinder 104 is hung on the lower corner of the window 116. Stop. The main body 101 is in a hanging state, but the back side 102b of the first housing 102m and the front side 103 of the second housing 103a are
The length of the connecting cylinder 104 must be adjusted in order to install the connecting cylinders 104 so as to touch the walls below the windows 116, respectively.

Furthermore, since the indoor unit 102 protrudes below the window 116, there is a drawback that the living space near the bottom of the window 116 is reduced.

Furthermore, when the main body 101 is operated, the drain water generated from the evaporator 105 is pumped into the drain pan by the drain pump 109.
The water must be pumped up to the height of the connecting cylinder 104 installed at the lower corner of the window 116 above 0B, and if the drain pump 109 stops for some reason, the drain pan 10B
There was a problem in that drain water overflowed and dripped below the indoor unit 102, potentially staining the indoor floor surface.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a flat structure having an air outlet and a suction port in the front part, and a ventilation passage communicating with the air outlet and the suction port inside. An indoor unit is configured, and an indoor heat exchanger and an indoor blower are provided in the ventilation path of the indoor unit, and an outdoor unit extending downward is provided at the lower rear end of the indoor unit. An outdoor heat exchanger and a compressor are provided which together with the indoor heat exchanger constitute a refrigeration cycle, and a support is provided on the side wall of the outdoor unit so as to be in contact with the wall surface of the house and whose degree of protrusion can be adjusted; A fixture is provided at the lower part of the indoor unit to hold the lower part of the window with the support metal fitting.

For production The effect of this technical means is as follows.

In other words, the horizontally long indoor unit and the vertically long outdoor unit are L.
Since they are joined in the shape of a letter, it not only ensures natural lighting, but also eliminates the need to adjust the joint relationship between the indoor and outdoor units in response to changes in the thickness of windows and walls at the installation site. In addition, since the walls of the house are used as sound insulating walls, they are excellent at insulating against outdoor noise such as those from the compressor. There is no need for a drainage pump, and there is no possibility of staining the indoor floor due to the drainage pump stopping.Furthermore, there is a fixture on the bottom of the indoor unit and a support that can be moved back and forth at the bottom of the front of the outdoor unit. Even if the lower frame of the window protrudes indoors or outdoors, it can be easily installed and fixed.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a main body of an integrated air conditioner, which is constructed by joining a horizontally long indoor unit 2 to the upper end of a vertically long outdoor unit 3 to form an L-shape.

A front grill 6 is provided on the front surface of the indoor unit 2 and has an indoor air outlet 4 at the top and an indoor air intake 5 at the lower side. is provided. Inside the indoor unit 2 is an indoor partition plate 8
The lower flow path 9 is the suction side, and the upper flow path 1o is the blowout side.
An indoor blower 11 that makes a U-turn on the air sucked in from the air and blows it out to the upper flow path 10, an indoor motor 12 that drives the indoor blower 11, and an indoor air guider 13 are provided. The evaporator 14 is installed diagonally so that the height is low in the depth direction, and the drain pipe 15 naturally guides the drain water generated from the evaporator 14 to the upper end of the condenser 20 in the outdoor unit by using the height difference. A drain pan 16 is provided to which the indoor unit 2 is connected.Also, a hole 17 long in the depth direction is provided near the center on the bottom surface of the indoor unit 2.
A fixture 19 is provided with a screw 18 that slides along 7 and fixes at any position.

Furthermore, the internal number of the outdoor unit 3 is the condenser 20. Outdoor side blowers 21 equipped with slinger rings are provided to face each other, and an outdoor side motor 22 for driving the outdoor side blowers 21, an outdoor air guider 23, and a compressor 24 are housed. Furthermore, an outside air outlet 25 is provided on the back side facing the condenser 20, and an inlet 26 is provided on the front side of the outdoor unit 3. Since the air is blown in a straight line, there is little ventilation resistance and condensation can be achieved with small power. It is configured to provide the necessary air volume. Further, on both sides of the lower front surface of the outdoor unit 3, screw-type supports 27 are provided that can be adjusted in the front and rear directions.

Since the integrated air conditioner is configured in this manner, by turning on the power switch attached to the operating section 7, the refrigeration cycle operation is performed and the interior of the room to be conditioned can be cooled. In particular, a very efficient condensing action can be obtained because the drain water is flowed from the upper end of the condenser 2o and because the outdoor ventilation passage is linear and requires only a small amount of blowing power.

In addition, in order to install the main body 1 of the above-mentioned integrated air conditioner,
Place the indoor unit 2 on the air-conditioned room side and install the outdoor unit 3.
At the bottom of the window 31, the front surface of the window 31 is in contact with the outer wall 30, and the fixture 19 provided on the lower side of the indoor unit 2 is slid, and the fixture 19 and the front surface of the outdoor unit 3 are attached to the frame at the bottom of the window 31. At the position where the
Tighten 8. Further, by adjusting the support 27 back and forth, the horizontality of the indoor unit 2 is ensured. This securely fixes the main body 1. Furthermore, the installation is completed by closing the window 31 that opens and closes vertically and joining it to the top surface of the main body 1, and attaching the shielding plates 32 to the openings formed on the left and right sides of the main body 1.

Effects of the Invention As is clear from the above embodiments, the present invention has a horizontally long indoor unit and a vertically long outdoor unit joined in an L-shape, so that it not only suppresses the height of the indoor unit and ensures lighting. During installation, the compressed root sound inside the outdoor unit, which is a loud sound source, is insulated by the wall, reducing noise. Additionally, changes in wall thickness can be accommodated without adjusting the indoor/outdoor connections.

Furthermore, since the drain pan located under the evaporator is located at the top of the main unit, it is possible to direct the outdoor hedrine water through the difference in height without using a drain pump, etc., and it does not pollute the indoor floor and also requires no support for installation. The main body can be kept horizontal simply by adjusting the , and the volume protruding into the room can be reduced to improve livability, among other effects.
