Description

[Detailed Description of the Invention] This invention relates to a separate air conditioner, and particularly relates to an improvement of its outdoor unit.

Conventionally, this type of outdoor unit was manufactured using the Utility Model Opening System of 1983, as shown in Fig. 4.
It is disclosed in Japanese Patent No.-52468.

That is, in FIG. 4, numeral 1 indicates the main body of the air conditioner made of synthetic resin, which has a gate shape.

4 is a front panel provided on the front surface of the main body 1; 10 is a rear panel provided on the rear surface of the main body 1; 8 and 15 are an air outlet provided on the front panel 4 and a suction port provided on the rear panel 10; is a blower installed facing this air outlet 8, 2
0 is a heat exchanger installed inside the suction port 15, and is connected to a large number of aluminum fins 25 arranged in parallel and a plurality of pipes 26 provided through the fins.

27 is a rib integrally molded with the main body 1, and the compressor 22
, the base plate 2 on which the blower 17 and the heat exchanger 20 are mounted are integrated.

Reference numerals 14 and 14 designate an air passage wall and a guide plate integrally formed with the knob 27, and 28 a heat exchanger support plate formed to protrude rearward from the rib 27 in correspondence with the guide plate 14.

In this case, the air conditioner has both ends of the heat exchanger 20 supported by integrally molded support plates 28, a lower part supported by the base plate 2, and a rear surface supported by attaching the rear panel 10. Fixed.

Therefore, in the conventional air conditioner, the casing is formed by combining multiple parts including the main body, the front panel, and the rear panel, and sufficient thermal efficiency cannot be obtained.

This idea was made in consideration of these points, and by constructing the casing from plastic, it was possible to install it on window frames, handrails, etc., with the aim of reducing weight and making the parts more complex.
The purpose is to sufficiently improve thermal efficiency and to ensure that air sucked in from the back side passes through the heat exchanger.

This invention will be explained in detail below with reference to the embodiments shown in FIGS. 1 to 3. 1 is an outdoor casing of an air conditioner;
It is composed of a base 2 and a cabinet 3.

The cabinet 3 has a front surface 4, a top surface 5, and both left and right sides 6 and 7 made of plastic, and has an air outlet 8 on the front surface 4 and an air suction port 9 on the top surface 5 and left side 6. .

On the other hand, the base 2 has a back surface 10 and a bottom surface 11 made of plastic into an L shape, and further has a partition plate 14 that partitions a heat exchange chamber 12 and a compressor chamber 13 formed integrally.

Reference numeral 15 denotes a back suction port formed in the back surface 10 of the base 2 on the side of the heat exchange chamber 12, and is provided in the shape of a ring.

Reference numeral 16 denotes a bottom suction port, which is formed as an opening in the bottom surface 11 of the base 2 on the heat exchange chamber 12 side.

Reference numeral 17 is a blower, which is installed on the back side 1 of the base 2 on the heat exchange chamber 12 side.
It is pivotally supported by a blower motor 19 fixed to a mounting boss 18 provided approximately in the center of a rear suction port 15 formed in the rear side, and faces the front air outlet 8 of the cabinet I.3.

20 is a heat exchanger disposed facing the back suction port 15 of the base 2, and is connected to the blower 17 and the blower motor 19.
It is formed into a coil shape surrounding the .

Reference numeral 21 denotes a recess on the back surface of the coil-shaped heat exchanger 20 so as to fit closely along the inner circumferential end surface of the base 2. It protrudes toward the front cabinet 3 from the inner end of the front cabinet 3.

22 is a compressor installed in the compressor room 13, and 23 is a leg that projects below the base bottom 11 and supports the casing 1 while allowing ventilation at the suction port 16 of the bottom 11.

In the outdoor unit of the air conditioner configured in this manner, the ventilation path is configured to draw air through the air suction ports 9 on the top surface 5 and left side surface 6 of the cabinet 3, the suction port 16 on the base bottom surface 11, and the rear suction port 15. As shown by the suction arrow, the air passes through the heat exchanger 20 and is blown out of the machine from the air outlet 8 on the front side along with the airflow from the blower 17.

As mentioned above, this idea consists of a base made of plastic integrally made of the bottom, back, and partition plates that partition the compressor room and heat exchange room, and a cabinet I made of plastic made of the top, front, and both sides.・Construct the casing by
A blower is installed in the heat exchange room to blow air toward the front of the cabinet, and a coiled heat exchanger is installed to surround the blower motor. Air suction ports are provided on the sides, the back and bottom of the base, and a recess is provided on the back of the base that closely contacts the inner circumferential edge of the heat exchanger, ensuring that the airflow from the rear suction port is particularly secure. It has great practical effects, such as being able to pass through it, sufficiently improving heat exchange efficiency, reducing costs by making it thinner and having more composite parts, and even making it lighter in weight. There is.
