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, there has been an outdoor unit of this type of separate air conditioner as shown in FIG.

In FIG. 1, reference numeral 1 denotes an outdoor casing of an air conditioner, which is divided into a compressor chamber 2 and a heat exchanger chamber 3.

Reference numeral 4 denotes a blower provided in the heat exchanger chamber 3, which is attached to a blower electric motor 6 so as to face the front.

Reference numeral 7 denotes an air suction port provided on the side surface and back surface of the housing 1 on the heat exchanger chamber 3 side, and 5 represents an air outlet, which is provided on the front surface of the housing 1.

Reference numeral 10 denotes an L-shaped heat exchanger, which is arranged opposite to the air suction lower of the housing 1.

In the outdoor unit configured in this way, the heat exchanger 10 is used by making the depth of the heat exchanger as thin as possible and widening the front area to widen the area through which the air passes, resulting in less resistance and quieter noise. It became.

However, as the prevalence of room air conditioners has increased in recent years, the number of installations in densely populated residential areas has increased, and the installation of outdoor units has become more diverse, not only on the ground but also on balconies, handrails, walls, and roofs. It has become necessary.

In response to these demands, conventionally, the air inlet was mainly located on the back, which resulted in the restriction of installing the back more than the required width.When considering further miniaturization and thinning, L-shaped In the arrangement of the exchanger, it is difficult to secure a sufficient area for the heat exchanger, and there are drawbacks such as the inability to promote smaller and thinner designs.

This idea was made in consideration of these points,
The objective is to provide an outdoor unit that is compact and thin, and that can be installed in a variety of ways.

This invention will be described in detail below with reference to the embodiment shown in FIG. 2. Reference numeral 1 denotes an outdoor casing of an air conditioner, which is divided into a compressor chamber 2 and a heat exchanger chamber 3.

Reference numeral 4 denotes a blower provided in the heat exchanger chamber 3, which is attached to a blower motor 6 so as to direct the blown air to the blow-off port 5 at the front.

Reference numeral 7 denotes an air suction port provided on the left side surface 8 as one side of the housing 1, and is also provided on the back surface 9 and the upper and lower surfaces 12.

A main heat exchanger 10 is formed by winding a plurality of spine fin tubes having a large number of needle-like fins, and covers the outer periphery of the blower 4 and the blower motor 6, and also covers one side of the housing 1. The left side surface 8 and the upper and lower surfaces 12 are arranged to face each other.

Reference numeral 11 denotes a rear heat exchanger, which is formed as an integral heat exchanger continuously with the main heat exchanger 10, and is arranged so as to face the entire surface of the air suction lower portion on substantially the rear surface 9 of the housing 1 excluding the blower motor 6. It is formed from a spine fin tube with multiple needle-like fins arranged and spirally wound into multiple turns.

In the outdoor unit configured as described above, the blower 4 is rotated by the drive of the blower motor 6, and primary air is sucked in from the air suction lower, and secondary air is blown out from the front air outlet 5.

This idea is constructed as described above, and has air inlets on one side, top and bottom, and back of the housing, an air outlet on the front, and a blower facing the front. −
A heat exchanger consisting of a main heat exchanger and a rear heat exchanger is arranged so as to face the air suction ports on the side, top and bottom, and rear, so that air is sucked in from one side, top and bottom, and back, and blown out from the front. Furthermore, since the rear heat exchanger has a space for arranging a part of the electric motor, it is extremely easy to reduce the depth of the front and rear of the casing, and to maximize the intake air path. In addition to this, the wind pressure loss is also small, making it possible to reduce noise.

In addition, it is possible to ensure sufficient performance with just a few holes in the back, and it can also be installed in narrow alleys where it is not desirable to open the back, making it possible to install it on walls, balconies, etc. in a variety of ways. It is something that can provide something to measure.

Note that the same effect can of course be obtained even if the heat exchanger 10 is wound in a single layer, and the heat exchanger 10 and the rear heat exchanger 11 may be provided independently.
The heat exchanger 10 and the rear heat exchanger 11 may be molded individually and then connected integrally through a connecting pipe (not shown).

Furthermore, as shown in FIG. 3, even if the heat exchanger 10 is formed with a plate-finned tube in the bottom shape, the same effect as in the above embodiment can be obtained.
