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.

4 is a blower provided in this heat exchanger room 3, and a blower motor 6 is attached so as to face the front.

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

Reference numeral 10 denotes an L-shaped heat exchanger, which is disposed 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, increasing the front area, and increasing the passage area of ventilation and air to reduce resistance and make noise. It was also slowing down.

However, as the prevalence of room air conditioners has increased in recent years, the installation locations of outdoor units have diversified, and it has become necessary to diversify the installation methods.

In response to these demands, conventionally the air suction port has been mainly installed on the back, and there is a restriction that the back should be installed more than the required width.When considering further downsizing and thinning, L-shaped heat exchangers In this arrangement, it was difficult to secure a sufficient area for the heat exchanger, and there was a drawback that it was not possible to promote further downsizing and thinning.

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.

Hereinafter, this invention will be explained in detail with reference to the embodiment shown in FIGS. 2 and 3. 1 is 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, and a blower motor 6 is attached to direct the blown air to the blower outlet 5 at the front.

Reference numeral 7 denotes an air suction port provided on the left side surface 8 of the housing 1, and also provided on the back surface 9 and the upper and lower surfaces (not shown).

Reference numeral 10 denotes a heat exchanger formed into a cylindrical shape by winding a plurality of spine fin tubes having a large number of needle-like fins, and is arranged to surround the blower 4 and the blower motor 6 so as to cover the outer periphery thereof.

A plate fin heat exchanger 11 is arranged on the rear surface of the heat exchanger 3 of the housing 1.

At this time, the cylindrical inner diameter of the spine fin heat exchanger 10 is smaller than the outer dimension of the plate fin heat exchanger 11.

A gap 12 is provided between the plate fin heat exchanger 11 and the spine fin heat exchanger 10, and a wind guide tube 13 is provided in this gap.

The rear end 14 of this air guide tube 13 is connected to the plate fin heat exchanger 1
The front end 15 has a truncated pyramid shape with the tip end entering the inside of the spine fin heat exchanger 10.

When assembling the outdoor unit configured in this way, first place the plate fin heat exchanger 11 against the rear surface of the housing, then attach the air guide tube 13 to the plate fin heat exchanger 11, and then attach the spine fin heat exchanger 11 to the plate fin heat exchanger 11. The exchanger 10 is connected to the wind guide tube 13
Attach by pressing it against the pyramid-shaped part.

Since the front end 15 of the air guide tube 13 is shaped like a truncated pyramid, the center of the cylindrical shape of the spine fin heat exchanger 10 can be aligned with the center of the air guide tube 13 by simply pressing it from the front.

After that, if the dimensions in the longitudinal direction are restricted by the housing 1, the spine fin heat exchanger 10 will not move, and the spine fin heat exchanger 10 can be mounted without using any fixing means.

Next, to explain the operating state, the blower 4 is rotated by the drive of the blower motor 6, primary air is sucked in from the suction port on the back side, and is passed through the plate fin heat exchanger 11 to perform heat exchange. Primary air is sucked in from the air suction lower, passed through the spine fin heat exchanger 11 for heat exchange, and secondary air is blown out from the front air outlet 5.

This idea is constructed as described above, and because the heat exchanger is placed toward the circumferential side and back of the casing, which has suction ports on the circumferential side and the back, it is smaller than the conventional one.
This can promote thinning, maximize the suction air path, and reduce wind pressure loss and noise.

In addition, a spine fin heat exchanger that can be easily rolled is placed on the circumferential side, and a plate fin heat exchanger that can be easily formed into a flat shape is placed on the back side, making the heat exchanger effective. It also has the feature that it can be installed at a low cost and can be manufactured at low cost.

In addition, a gap is provided between the plate fin heat exchanger and the spine fin heat exchanger, and a wind guide tube with a conical or truncated pyramid-shaped front end is installed in this gap, so it can be easily pressed down with the housing during assembly. It has extremely excellent practical effects, such as being able to fix the spine fin heat exchanger and smoothly guiding the air that has passed through the Flay fin heat exchanger.
