Description

[Detailed Description of the Invention] Field of Application of the Invention The present invention relates to an air conditioner, and particularly to an air conditioner suitable for reducing the depth dimension of the air conditioner.

Background of the idea First, a conventional air conditioner will be explained with reference to FIG.

Incidentally, there is a similar one in Japanese Utility Model Application No. 55-3231.

FIG. 1 is a longitudinal cross-sectional view of a conventional air conditioner, and arrows in the figure indicate the direction of wind flow.

In FIG. 1, reference numeral 1 denotes a base, which also serves as a casing for the blower and has a structure to which a heat exchanger, a decorative cover, etc. can be attached.

Reference numeral 2 denotes a blower, which is mounted on the base 1 together with a drive motor (not shown) and the like.

3 is a decorative cover, which has an air inlet 3a at the top and an air outlet 3b at the bottom integrally formed;
It covers the entire base 1, blower 2, etc.

4 is a heat exchanger, located between the blower 2 and the decorative cover 3;
It is attached corresponding to the suction port 3a.

Reference numeral 5 denotes a dew tray for receiving dew condensed on the heat exchanger 4, and its tip is connected to a drain pipe (not shown).

Note that D1 indicates the depth dimension of the air conditioner.

In a conventional air conditioner with such a structure, the depth dimension D1 of the machine body corresponds to the total dimension of the base 1, the blower 2, the decorative cover 3, the heat exchanger 4, and the gaps between them. The disadvantage was that it became large.

Therefore, in order to reduce the depth dimension D1, a method has been used to reduce the diameter of the blower 2, but this reduces the amount of air blown and reduces the cooling capacity.

One way to compensate for the decreased cooling capacity is to reduce the fin pitch of the heat exchanger 4 to increase the heat transfer area.
This has the disadvantage that the increase in ventilation resistance when the fin pitch is reduced further reduces the amount of air blown.

Purpose of the invention This invention was made to improve the shortcomings of the conventional technology.It reduces the depth of the air conditioner, reduces the installation space, and makes the living space more efficient without reducing the air conditioning capacity of the air conditioner. Its purpose is to provide air conditioners that can.

Summary of the invention The structure of the air conditioner according to the invention is that a heat exchanger and a blower are arranged on the base, and an air inlet is provided at the upper part of the front to cover them, and an air outlet is provided at the lower part. In an air conditioner equipped with a decorative cover equipped with
A, a first heat exchanger 7 having a cross fin pipe structure is placed opposite the suction port 6a, and a cross plate having a fin pitch different from that of the first heat exchanger 7 is placed on the upper back side of the first heat exchanger 7. A second heat exchanger 8 having a fin pipe structure is arranged in parallel with a blower 2 on the lower back side of the first heat exchanger 7.

Embodiment of the invention Hereinafter, an embodiment of the invention will be described with reference to FIGS. 2 and 3.

FIG. 2 is a longitudinal sectional view of an air conditioner according to an embodiment of the present invention, and FIG. 3 is a partially enlarged perspective view of a heat exchanger thereof.

In the figure, parts with the same symbols as in FIG. 1 are the same parts as in the prior art, and arrows in the figure indicate the direction in which the wind flows.

In the figure, 6 is a decorative cover in which an air inlet 6a at the top and an air outlet 6b at the bottom are integrally formed, and covers the entire base 1, blower 2, etc. .

In particular, the suction port 6a is in the form of a continuous suction port from the upper part of the front surface of the air conditioner to the top surface of the body.

Reference numeral 7 denotes a first heat exchanger, which has a cross-fin pipe structure designed to be thin, and is connected to the suction port 6a of the decorative cover 6.
It is placed in a position opposite to.

Reference numeral 8 designates a second heat exchanger, which is shorter in longitudinal dimension than the first heat exchanger 7 and has a cross-fin pipe structure designed to be thinner, and is disposed on the upper back side of the first heat exchanger 7. There is.

The fin pitch P2 of the second heat exchanger 8 is smaller than the fin pitch P1 of the first heat exchanger 7, as shown in FIG.
It is designed so that I>P2.

The lower part of the second heat exchanger 8 is formed into an inclined shape, and the tip of the inclined part 8a is brought into contact with the back surface of the first heat exchanger 7.

Reference numeral 9 denotes a dew pan, which is disposed below the first heat exchanger 7.

The blower 2 is arranged in parallel on the lower back side of the first heat exchanger 7.

Note that D2 indicates the depth dimension of the air conditioner.

In such an air conditioner, since only the thin first heat exchanger 7 is disposed in front of the blower 2, the depth dimension D2 can be reduced.

Further, the second heat exchanger 8 has a small fin pitch P2 and a large heat transfer area, and since the suction port 6a is open to the top surface, the amount of air passing through this portion increases, and the amount of heat exchanged also increases.

Furthermore, this structure allows the lower part of the second heat exchanger 8 to be connected to the inclined part 8a.
Since the tip of the tip is in contact with the back surface of the first heat exchanger 7, dew condensed on the second heat exchanger 8 is also guided from this back surface to the first heat exchanger 7, and is placed in the dew pan. It has the effect of flowing to 9.

Effects of the Invention As stated above, the present invention provides an air conditioner that reduces the depth of the machine body without reducing the air conditioning capacity of the air conditioner, reduces installation space, and makes the living space more efficient. can do.
