ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. § 119 from an application entitled WINDOW TYPE AIR CONDITIONER HAVING INJECTION-MOLDED UPPER AND LOWER CASINGS earlier filed in the Korean Industrial Property Office on Sep. 10 , 1998, and there duly assigned Serial No. 37259/1998.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an air conditioner, and more particularly, to a window type air conditioner having upper and lower casings which are formed by injection molding and are coupled with each other.
2. Description of the Prior Art
Generally, as shown in
FIG. 1
, an air conditioner includes a front cover
10
on which a suction grill
11
and a discharge grill (not shown) are formed, a casing
20
on which a plurality of air holes
21
are formed, and a baseplate
30
which is disposed beneath the casing
20
.
As shown in
FIG. 1
, such a window type air conditioner is mounted through a window (G) or a wall (W). Further, in the portion of the air conditioner which is exposed outside the wall (W), i.e., outside the building, a compressor, a condenser, and a cooling fan are installed, while an evaporator and a blowing fan are installed in the portion protruding inward of the wall (W), i.e., inside the building. All the above parts are mounted on the baseplate
30
, and then the casing
20
and the front cover
10
are mounted on the baseplate
30
.
Meanwhile, the conventional window type air conditioner constructed as above has drawbacks as follows: Since the elements for forming the appearance of the air conditioner, i.e., the casing
20
and the baseplate
30
are made of the metallic material, which is quite heavy and expensive, the manufacturing cost for the air conditioner increases, and also, the manufacturing and delivery processes become inefficient. Further, since certain parts of the casing
20
and the baseplate
30
are exposed to the outside, the air conditioner has a problem of being easily corroded by the outside environment.
In order to solve the above problem, as shown in
FIG. 2
, a window type air conditioner having an injection-molded casing has been suggested. In such an air conditioner, a casing
40
is comprised of a lower casing
41
and an upper casing
42
. The front portion of the casing
40
is attached to a front cover
50
having both suction and discharge grills
51
and
52
on the front side thereof. The upper and lower casings
41
and
42
have a plurality of air holes
41
a
and
42
a
on the respective sides thereof. The upper and lower casings
41
and
42
are molded of materials such as synthetic resin, or the like, by injection. In such an air conditioner, since the casing
40
is made by the injection molding, the manufacturing cost decreases, and the assembly and delivery can be performed conveniently. Further, there is no risk of having any corrosion.
The above conventional air conditioner, however, has drawbacks as follows: In order to make the injection molding easier, sides of the upper and lower casings
41
and
42
are curved, respectively. More specifically, in order to easily detach the molding from the mold, the respective sides of the upper and lower casings
41
and
42
are curved. Accordingly, when such an air conditioner having curved sides is installed through the window, as shown in
FIG. 3
, there are gaps
62
formed between the casing
40
and a frame
61
disposed around the window for installation of the air conditioner. Such gaps
62
result in a deteriorated cooling efficiency of the air conditioner, since the outside and inside air flow therethrough. Further, the appearance of the air conditioner is deteriorated. Accordingly, when such a conventional air conditioner is installed, the gaps
62
should be sealed with a separate sealing member.
Further, since the upper and lower casings
41
and
42
are made of materials such as synthetic resins, or the like, the upper and lower casings
41
and
42
have a much lower strength.
SUMMARY OF THE INVENTION
The present invention has been made to overcome the above problems of the prior art, and accordingly, it is an object of the present invention to provide a window type air conditioner having an injection-molded casing which is manufactured more efficiently with less cost, and does not form a gap with a window.
Another object of the present invention is to provide a window type air conditioner having a strong casing.
The above objects are accomplished by a window type air conditioner according to the present invention, including: injection-molded upper and lower casings; and upper and lower flange 5 sections formed on both sides of the upper and lower casings, respectively. The upper and lower flange sections are integrally injection-molded with the upper and lower casings. The upper and lower flange sections are formed vertically, and have plane outer sides, respectively. Due to the presence of the respective flange sections, there is no gap defined between the air conditioner and window when the air conditioner is installed through the window. Further, the strength of the respective casings is increased.
Preferably, the upper and lower flange sections have inner hollow portions therein, respectively. Accordingly, it is easier to injection-mold the upper and lower casings to have plane outer sides, respectively.
Further, it is preferable that the lower and upper casings have air intake holes and air exhaust holes, respectively, to intake and exhaust the outside air.
