Abstract

PROBLEM TO BE SOLVED: To prevent a part of diffused air from flowing into an air inlet on one side and avoid a drop in the efficiency of heat exchange by forming an air inlet on one side with a large number of opening faced behind and the eaves which cover the openings. SOLUTION: The air sucked up from an air inlet 3a is heat-exchanged with a heat exchanger 1 provided in a main body 1 and arraigned to blow off the heat-exchanged air from an air outlet 2a with a fan. An air inlet 3a provided on one side surface 3 of an outer shell comprises a large number of openings (b) provided with an outer shell made of a sheet metal and provided to face in the rear part of the side surface 3 and the eaves (a) formed expandingly outward by throttling the front of the openings (b). Since a part of the air blowing off from the air outlet 2a is sucked up from the air inlet 3a of one side surface 3 as a result, this construction makes it possible to prevent heat exchange efficiency in the main body 1 from being degraded.

2. Description of the Related Art In a conventional air conditioner outdoor unit, for example, as shown in FIG. 2, a suction port 3a is provided on the back surface and one side surface 3 of an outer shell constituting a main body 1, and a front surface 2 has an air outlet 2a. Was provided.

In the above structure, since the air outlet 2a and the air inlet 3a provided on the one side surface 3 are close to each other, heat is exchanged in the main body 1 and is blown out from the air outlet 2a. A part of the blown air is sucked in through the suction port 3a and exhibits a so-called short circuit phenomenon.
There is a problem that the heat exchange efficiency in the interior is reduced.

[0004]

In view of the above problems, the present invention provides a structure in which part of the air blown from the air outlet on the front surface of the main body does not flow into the suction port on one side. An object is to provide an outdoor unit of an air conditioner that the user has.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is an air conditioner in which a suction port is provided on the back surface and one side surface of the outer case and an air outlet is provided on the front surface. In the outdoor unit of the machine, the suction port on the one side surface includes a large number of openings facing the rear and an eaves section covering the openings.

Further, the outer body is formed of sheet metal, and the eaves portion is provided with a vertically extending slit for forming the opening portion on the one side surface, and the front portion of the slit is drawn out by drawing. It is configured to bulge in one direction.

Further, the outer case is made of synthetic resin, and the eaves are integrally formed in front of the opening so as to project outward.

Further, the eave portion is formed into a curved surface.

[0009]

With the above structure, the outdoor unit of the air conditioner has a structure in which a part of the air blown out from the air outlet on the front surface of the main body does not flow into the air inlet on one side.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 (A), FIG. 1 (B), and FIG.
In (C), 1 is an outdoor unit main body of the air conditioner, and the main body 1 is configured to be covered by an outer case including an upper surface, front and rear surfaces, and both side surfaces.

Reference numeral 2 denotes a front surface of the outer case, and the front surface 2 has an outlet for blowing out the air that has undergone heat exchange in the main body 1.
2a is provided. Reference numeral 3 denotes one side surface of the outer case, which has a suction port 3a for sucking air on the same side surface 3 and the back surface.

With the above structure, the air sucked from the suction port 3a is heat-exchanged by the heat exchanger (not shown) arranged in the main body 1 and blown by the blower fan (not shown). It is configured to blow out from the exit 2a.

In the above construction, the suction port 3a provided on the one side surface 3 of the outer shell is the outer shell as shown in FIG. 1 (B) as a first embodiment corresponding to claim 2. A configuration including a large number of openings b formed by sheet metal and provided on the one side surface 3 so as to face rearward, and an eaves portion a formed by expanding the front of the openings b outward by drawing. Has become
As a result, a part of the air blown from the air outlet 2a is prevented from being sucked in from the air inlet 3a of the one side surface 3, and the heat exchange efficiency in the main body 1 is not lowered. It becomes a structure.

The eaves portion a is formed by forming a vertically extending slit for forming the opening b in the one side surface 3 and bulging outward in front of the slit by drawing. With this configuration, the dimension and shape are accurately finished, and the configuration is advantageous in terms of cost. Further, the eaves portion a is formed in a curved surface shape, whereby air is effectively sucked from the opening portion b and the appearance is not impaired. .

Further, in the above-mentioned structure, the suction port 3a provided on the one side surface 3 of the outer case has a structure as shown in FIG. 1 (C) as a second embodiment corresponding to claim 3. The body is made of synthetic resin, and includes a large number of openings b provided rearwardly on the one side surface 3 and an eaves portion a formed integrally with the opening b and protruding outward. With this structure, a part of the air blown out from the air outlet 2a is prevented from being sucked in from the suction port 3a of the one side surface 3, and the heat exchange in the main body 1 is performed. The structure does not reduce efficiency.

The outer case is made of synthetic resin, which is more cost effective than an outer case made of sheet metal. The eaves part a is integrally formed in front of the opening b. By projecting outward, the dimensional shape can be accurately finished and the cost is advantageous. Further, the eaves portion a is formed in a curved surface shape, whereby air is effectively sucked from the opening portion b and the appearance is not impaired. .

With the above structure, FIG. 1A and FIG.
As shown in (B) and FIG. 1 (C), when sucking air from the suction port 3a provided on the one side surface 3 of the outer case,
Air in which a part of the blown air blown out from the blowout port 2a is shielded by the eaves part a to prevent it from being sucked in from the suction port 3a so as not to lower the heat exchange efficiency in the main body 1. It becomes the outdoor unit of the harmony machine.

[0018]

As described above, according to the present invention, a part of the air blown out from the air outlet on the front surface of the main body is prevented from flowing into the air inlet on one side, and the heat exchange efficiency is not lowered. It becomes the outdoor unit of the air conditioner.
