ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a solenoid valve supporter of Kim-chi refrigerator, and more specifically to a solenoid valve supporter of Kim-chi refrigerator that is guaranteed of the original functions of the solenoid valve with very simplified structure for mounting a plurality of solenoid valves by positioning every solenoid valve corresponding to the evaporators on one supporter body with the same intervals and flowing and emitting the refrigerants into the plurality of solenoid valves through the supporter.
(2) Description of the Prior Art
In general, a refrigerator is a type of cooling apparatus. The refrigerants are condensed and liquefied under a high pressure by using a condenser. The condensed refrigerants are moved to an expansion valve having a tube of a small diameter. Here, the refrigerants are instantaneously vaporized in an evaporator, and thus the temperature is dropped to generate cooling air. The cooling air is supplied to a main body of the refrigerator, thus maintaining freshness of the food in the refrigerator.
The refrigerant vaporized in the evaporator by absorbing heat are moved from a compressor to a condenser, and condensed and liquefied in the condenser, discharging heat. Thereafter, the above-described procedure is repeated to perpetually perform the cooling operation.
On the other hand, a Kim-chi refrigerator introducing the refrigerating principle to ripen Kim-chi and maintain freshness of Kim-chi has been popular. Such a Kim-chi refrigerator is made small. Accordingly, while a general refrigerator has a door on its front side, the Kim-chi refrigerator has a door on its top surface in a hinge type.
The interior of the Kim-chi refrigerator contains a cooling and heating device. Accordingly, when ripening Kim-chi, the temperature inside the container is raised by making the heater a heating device operates thereby ripening Kim-chi kept in a containing room. After ripening Kim-chi properly, the heater stops and simultaneously a cooling device is operated, so the temperature of the containing room is maintained properly, thereby capable of maintaining Kim-chi with its taste and freshness for a long period of time.
Recently, a drawer type Kim-chi refrigerator has been suggested to insert a drawer into its main body. The upper opening and shutting type Kim-chi refrigerator has a Kim-chi storage room positioned vertically and the door mounted on the Kim-chi storage room to open upward, and the drawer type Kim-chi refrigerator has a drawer providing a Kim-chi storage room positioned horizontally. Recently the compound type Kim-chi refrigerator with an upper door of the upper opening and shutting type Kim-chi refrigerator and a drawer of the drawer type Kim-chi refrigerator has been developed and in use.
The conventional compound type Kim-chi refrigerator has the same structure as shown in the
FIGS. 1
a
and

b.
As illustrated in
FIGS. 1
a
and
1
b,
generally there are two Kim-chi storage rooms
20
divided on the upper part of body
10
of the Kim-chi refrigerator that constitutes the outer appearance, and there is a mounted hinge
40
on the upper part of the back of body
10
in order to open and close by lifting the two upper door
30
upwards, which enables the two Kim-chi storage rooms
20
to open and close.
In Kim-chi storage room
20
, the separate Kim-chi storage vessels
21
is inserted to ripen and store Kim-chi.
Also, on the lower portion of the Kim-chi storage rooms
20
, a drawer
53
providing the drawer type storage room
50
is positioned. Usually, this drawer type storage room
50
is designed mainly to store vegetable chamber. This vegetable chamber maintains the indoor temperature from the cool air supplied from the evaporator
100
installed separately.
This drawer type storage room
50
is structured so that mostly vegetables and fruits, etc. can be kept fresh, and the drawer type storage room
50
is built in a way that it is equipped with a handle
52
wholly conjoined with a drawer
53
in order to open and close the receipt barrel
51
which can store and maintain vegetables, etc. In addition, on the backside of the drawer type storage room
50
, a machine room
70
is separately positioned where the compressor
60
and a condenser are set in place for the cooling unit.
The control for all the Kim-chi refrigerator operation is attained by the modulating panel
80
provided on the front side of the body
10
, and the insulating material
90
is filled inside the body
10
through the foaming molding to raise the insulating effect from the exterior air.
Meanwhile, since the compounded Kim-chi refrigerator with two Kim-chi storage rooms
20
and the drawer type storage room
50
as the above mentioned is fully equipped with an evaporator
100
that supplies cool air in each interior space, a solenoid valve is provided in order to smoothly supply the refrigerants by modulating the flow of the refrigerants by each evaporator.
At this point, by briefly examining the structure of the solenoid valve used in the conventional Kim-chi refrigerator, as it is shown in
FIG. 2
, this is composed of the valve body
220
with the inlet port
160
and the outlet port
180
through which the refrigerants are flown and emitted, the cylinder
110
installed adhesively to this valve body
220
, the plunger
130
which closes the inlet port
160
through the lower edge sealing cap
120
by the pressure of spring
210
, and the cover
190
embedded with the coil
170
possible of the refrigerants to flow by pulling the plunger
130
, magnetized by the exterior power transmitted through the wire
150
.
Then, since the inlet port
160
and the outlet port
180
are connected with the inlet pipe
200
and the outlet pipe
140
each coupled with the refrigerant hose, as the coil
170
is charged with electricity, and the plunger
130
overcomes the power of spring
210
to be raised, the refrigerants flown through the inlet pipe
200
are emitted out of the flow-out pipe
140
through the inlet port
160
and the outlet port
180
, making the refrigerants flow.
On the other hand, in case of applying the solenoid valve constituted as aforementioned to the compound type Kim-chi refrigerator, three solenoid valves are usually furnished corresponding to every evaporator installed in three space.
Nevertheless, in composing each of the three solenoid valve separately to correspond with each evaporator, there is an obvious discrepancy that this structure becomes very complicated, and there is another problem where setting in each solenoid valve inside the machine room loses its assembling efficiency.
SUMMARY OF THE INVENTION
The objective of this invention is to provide a solenoid valve supporter of Kim-chi refrigerator supported with a number of (for example, three pieces) solenoid valves to discharge the refrigerants flown through one inlet pipe to every solenoid valve by establishing plurality solenoid valves in one supporter body and provide the solenoid valves of Kim-chi refrigerator with very simple structure by emitting the refrigerants to the corresponding evaporator through the outlet pipe according to the controlled amount in every solenoid valve.
Another objective of this invention to provide a solenoid valve supporter of Kim-chi refrigerator capable of enhancing the assembling efficiency by fixing the simple structured solenoid valve on the wall of the machine room using one bracket.
In addition, the other objective of this invention to provide a solenoid valve supporter of Kim-chi refrigerator capable of preventing the noise occurring from the solenoid valve being transmitted to the machine room wall surface through the bracket by inserting the sound-absorbing material between the bracket and the machine room wall surface in fixing the solenoid valve on the machine room wall surface by using the bracket.
In accordance with this present invention a solenoid valve supporter of Kim-chi refrigerator Kim-chi refrigerator
