ABSTRACT:
This nonprovisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. 2001-0087396 filed in KOREA on Dec. 28, 2001, which is herein incorporated by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an outdoor unit for an air conditioner, and particularly, to an outdoor unit for an air conditioner having a reinforcing structure which increases a supporting intensity to reduce a vibration and to minimize a fabrication cost.
2. Description of the Background Art
Generally, an air conditioner is an apparatus for maintaining an indoor environment to be the most profitable state by conditioning a temperature, humidity, cleanliness of air and air flow.
A general refrigerating cycle includes a compressor for changing a refrigerant into gas of a high temperature and a high pressure from gas of a low temperature and a low pressure; a condenser for condensing the gaseous refrigerant compressed from the compressor into a liquid state and for emitting heat outside; an expander having a capillary tube for changing the liquid refrigerant changed from the compressor into a saturated liquid state of a low temperature and a low pressure; and an evaporator for evaporating the saturated liquid changed from the expander into a gaseous state of a low pressure and for absorbing exterior heat.
The general air conditioner using the refrigerating cycle is divided into an outdoor unit including the compressor and the condenser and an indoor unit including the compressor, the condenser, and the evaporator. The outdoor unit and the indoor unit are connected to each other by a connecting pipe.
When a large cooling capacity is required, the outdoor unit for an air conditioner has to increase its size, a large fan is installed therein, and is used a structure that a fan is arranged to an upper portion of the outdoor unit so as to suck air at a circumference of the outdoor unit and to exhaust the air to the upper portion of the outdoor unit.
Referring to
FIGS. 1 and 2
, an outdoor unit for an air conditioner in accordance with the conventional art will be explained.
FIG. 1
is a perspective view showing an outdoor unit for an air conditioner in accordance with the conventional art, and
FIG. 2
is a sectional view taken along line II—II of FIG.
1
.
Referring to
FIGS. 1 and 2
, the outdoor unit for an air conditioner in accordance with the conventional art comprises a case
11
forming a receiving space therein and provided with an inlet
16
and an outlet
15
for sucking and exhausting air; a compressor
32
installed at an inner side of the case
11
for compressing a refrigerant; a fan
36
installed with a predetermined distance from the compressor
32
and rotated by a rotating force of a motor
33
for sucking and exhausting air; and a condenser
34
installed at a circumference of the case
11
for emitting heat from the refrigerant compressed from the compressor
32
and for condensing the refrigerant into a liquid state.
The case
11
includes a base plate
12
installed at a bottom portion so as to install components such as the compressor
32
and etc.; an upper plate
14
installed above the base plate
12
with a predetermined distance and provided with an inlet
16
therebetween; and a plurality of support members
20
connected between the base plate
12
and the upper plate
14
and arranged with predetermined intervals towards a circumference direction of the case
11
.
The upper plate
14
has at least one outlet
15
for exhausting air, and the outlet
15
is provided with a grill
17
for protecting the fan
36
from outside.
The plurality of support members
20
are arranged towards an outer circumference direction of the upper plate
14
and the base plate
12
, thereby supporting the case
11
.
Operations of the outdoor unit for an air conditioner in accordance with the conventional art will be explained.
First, if the compressor
32
is driven, a refrigerant compressed from the compressor
32
emits heat by passing the condenser
34
. At this time, the fan
36
promotes the emission of the refrigerant by sucking exterior air through the inlet
16
.
Also, the refrigerant emitted from the condenser
34
is reduced in a pressure and expanded through the expander (not shown) formed with a capillary tube and provided to the indoor unit (not shown). Then, the refrigerant is compressed in the compressor
32
again, and repeats the cycle.
The outdoor unit for an air conditioner is provided with a large fan and a compressor to enhance condense and evaporation efficiencies, thereby generating a noise and a vibration when the fan and the compressor are driven.
Moreover, if sizes of the compressor and the fan are increased to enhance a cooling capacity, a size of the outdoor unit for an air conditioner is also increased. At this time, when the compressor and the fan are driven, a supporting intensity of the outdoor unit is relatively weakened, so that a gap and a vibration are generated.
Accordingly, to overcome said problems, as shown in
FIG. 3
, a lattice-type sash composed of a plurality of vertical rods
52
and a plurality of horizontal rods
54
is installed at an outer side of the outdoor unit so as to prevent the vibration.
However, the outdoor unit for an air conditioner having the lattice-type sash
50
requires many components to fabricate the sash
50
, complicated processes, and an expensive production cost.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide an outdoor unit for an air conditioner having a reinforcing structure which increases a supporting intensity, simplifies a construction and a fabrication, and reduces a fabrication cost.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an outdoor unit for an air conditioner having a reinforcing structure comprising a base plate arranged at a bottom portion of a body of the outdoor unit, an upper plate arranged at an upper portion of the body of the outdoor unit, a plurality of support members connected between the base plate and the upper plate and arranged towards a circumference of the body with predetermined intervals, and a reinforcing member arranged between the support members for supporting the body of the outdoor unit, wherein the reinforcing member includes an upper reinforcing rod connected to both sides of the upper plate and prolonged to a lower direction, a lower reinforcing rod connected to both sides of the base plate and prolonged to an upper direction, and a connection reinforcing rod connected between the upper and lower reinforcing rods.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an outdoor unit for an air conditioner having a reinforcing structure, wherein the upper reinforcing rod consists of first and second upper rods connected to each other by fixing one side thereof to the upper plate respectively and by being prolonged to a lower direction with a predetermined angle, and the lower reinforcing rod consists of first and second lower rods connected to each other by fixing one side thereof to the base plate respectively and by being prolonged to an upper direction with a predetermined angle.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an outdoor unit for an air conditioner having a reinforcing structure, wherein the first and second upper rods and the first and second lower rods have a declined angle of 30° for the upper plate and the base plate respectively.
The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
