FIELD OF INVENTION 
The invention is related to providing an electronics cooker of a separating 
type having bodies which is divided into a heating portion, an adjusting 
portion and an oscillating portion, and particularly to providing an 
electronics cooker of a separating type having an improved cooling 
apparatus. 
BACKGROUND OF INVENTION 
A conventional electronics cooker was generally provided with a heating 
portion, an adjusting portion and an oscillating portion mounted 
integrally in one body. On the other word, the heating portion includes at 
least one burner in which a heating coil is properly arranged. The 
oscillating portion having the high frequency generating inverter is 
mounted directly under the heating coil, and also the adjusting portion is 
mounted near the heating portion. 
Therefore, such like cookers have the body of the relative larger volume. 
Due to it, it is not easy to transport or install the cooker. When any one 
of a heating portion, an adjusting portion and an oscillating is becoming 
out of order, all parts of the cooker must be exploded, the amount of the 
repairing service is increased, while it takes the relative longer time in 
making for repair. Further, the super-heat emitted from the heating coil 
and the inverter is transferred to the adjusting portion adjacent to them, 
thereby influencing ill on the operation of the electronics cooker. In the 
worst case, the mal-function of the electronic cooker has been caused and 
the operating noise of the cooling fan has been occurred loudly. 
Especially, in the event that the electronics cooker is provided with the 
cooling means, U.S. Pat. No. 4241718 issued to Eugene J. Barnett disclosed 
a structure of a range body cooling system for controlling the temperature 
of user accessible range body surfaces during a pyrolytic, oven-cleaning 
operation, in which a pair of downwardly extending, elongated channel 
members having U-shaped cross sections is positioned within the range 
body, one under each upper front corner thereof between a respective side 
wall of the range body and an opposed oven linear side wall, aperatured, 
horizontal mounting flanges from which the channel members are hung 
advantageously allow for the unimpeded upward flow of convected air along 
the entire lengths of the heat sink channel members. Herein, it is known 
that this patent concerns the spontaneous cooling using the convection 
phenomenon. 
But, the heat sink member and the air flowing passages were arranged in the 
outer wall and at least one sides of the body, together or respectively. 
The grill structure for discharging the hot air was installed at one side 
of the adjusting portion or the predetermined area adjacent to the wall on 
which the cooker is positioned. Also, the inlet portion for intaking the 
cooling air to be circulated was established in opposition to the side of 
the adjusting portion. Due to it, it have been disadvantages that the 
volume of the applicance equipment is made big, its installing area is 
enlarged and the number of its parts is increased, thereby its assembly 
being difficult. 
Japan Laid-Open Patent No. Sho 59112134 disclosed the structure for 
discharging the hot air, in which the heating cooker includes a cabinet 
for receiving its body, a discharging duct for emitting the hot air from 
its body, a discharging cover mounted between the discharging duct and the 
heating chamber wall on the upper portion of the discharging duct, the 
ventilating passage being formed between said discharging duct and said 
heating chamber wall. But this patent has also disadvantages identifying 
to those of U.S. Pat. No. 4241718. 
Also, Japan Laid Open Publication No. Sho 59-74435 suggested that the 
cooker is provided with the high frequency oscillator and second heating 
source, such as the electrical heater or the burner, etc. and especially 
the shutter is mounted in the ventilating passage for acting to discharge 
the hot air from the heating chamber as well as to intake the cooling air 
from the outside, thereby opening or closing the ventilating passage 
according to the shape change based on the temperature of the shape memory 
alloy. For example, at least one ventilating passages are respectively 
formed at both sides and the rear side of the cooker, the fan is mounted 
at any one of both sides, and the shutter is mounted at the rear portion. 
Therefore, each of predetermined spaces for installing the cooling 
apparatus in the cooker must have been occupied at three sides, with a 
result that the whole volume of the cooker was enlarged. Herein, it is 
known that the prior art has been requested to assure the predetermined 
space for cooling the heating portion in at least one sides. 
Accordingly, in order to resolve the above disadvantages, the main object 
of the invention is to provide the electronics cooker of the separating 
type, which is divided into the heating portion, the adjusting portion and 
the oscillating portion and may be adopted to anyone of the free standing 
range and the platform range. 
The other object of the invention is to provide the electronics cooker of 
the separating type having the cooling means, in which the cooling means 
includes the air ventilating portion formed at only one side of the 
cooker, the adjusting portion arranged adjacent to the air ventilating 
portion the cooling fan mounted within air ventilating portion. 
The another object of the invention is to provide the electronics cooker of 
the separating type having the other cooling means for cooling the 
operating parts of the oscillating portion, in which the oscillating 
portion is constructed as dual upper and lower compartment structures to 
force the cooling fan mounted in the upper compartment to circulate the 
cooling air intaked from the upper compartment into the lower compartment. 
SUMMARY OF INVENTION 
Thus, the invention can be adopted to the electronics cooker of the free 
standing type or the platform type and comprises a heating portion mounted 
on the upper of the cooker body and provided with at least one ovens 
having the heating coil, an adjusting portion mounted adjacent to the 
heating portion with the air ventilating portion being extended at a plane 
identical thereto and then at a downward direction thereof, cooling means 
mounted in the air ventilating portion to force the cooling air to be 
circulating in the heating portion, an oscillating portion having dual 
upper and lower compartments divided by the compartment wall, in which the 
operating parts of the oscillating source are arranged in the lower 
compartment, cooling means mounted in the upper compartment to force the 
cooling air to cool the osillating source in the lower compartment, and at 
least one means allowing the heating portion, the adjusting portion and 
the oscillating portion to be electrically connected to each other. 
Therefore, the invention prevents the high temperature of the heating 
portion from transferring to the oscillating portion and the adjusting 
portion, so that it is not anxious about the ill influence on the 
oscillating portion or the adjusting portion, such as the mal-function of 
the heating portion and the poor operation of the adjusting portion. 
Also, the invention is provided with two cooling means mounted to cool the 
heating portion and the oscillating portion, respectively, so that the 
cooling efficiency may be enhanced. 
Also, the invention is provided with the heating portion and the 
oscillating portion separated from each other, so that the body of the 
heating portion may be thinner than that of the prior art to make an 
investigation for the variety of its design. And the ventilating portion 
formed in at least one sides of the cooker body is decreased by one side, 
so that the whole volume of the applicance equipment may be reduced.

DETAIL DESCRIPTION OF INVENTION 
In drawings, electronics cooker 1 is comprised of heating portion 2, 
adjusting portion 3 and oscillating portion 4. These heating portion, 
adjusting portion and oscillating portion are respectively constructed in 
their body. Heating portion includes case 7, in which at least one ovens 
having heating coil are properly arranged. Case 7 has numerous holes 8 
perforated at its bottom throughout the predetermined area near each of 
oven 6 to discharge the air therefrom and cutting portion 9 formed at one 
side thereof to introduce the cooling air thereinto as shown in FIG. 3 and 
FIG. 4. 
Adjusting portion 3 is mounted adjacent to heating portion 2. As shown in 
FIG. 2, this adjusting portion 3 includes case 10 in the form of the 
scoop, the upper of which is opened. This case 10 has the cover provided 
with control knobs(not shown) for controlling the on-off time and the 
heating time of the applicance equipment and the heating level and PCB(not 
shown) mounted therein. On the other hand, air ventilating portion 3a is 
constructed adjacent to adjusting portion 3 with its predetermined length 
being extended downward below adjusting portion 3. Thus the inner portion 
of air ventilating portion 3a is formed as air ventilating passage 11, and 
its bottom is formed as inlet portion 12 for intaking the cooling air from 
the outside. Fan 16 serving as the cooling means is properly mounted in 
air ventilating passage 11 by means of bolts 13 having the predetermined 
length, pieces 14 and nuts 15. Air ventilating portion 3a is cut out at 
one side of the area corresponding to adjacent to cutting portion 9 of 
heating portion 2. Air flowing guider 17 is covered on the upper of air 
ventilating portion 3a to separate adjusting portion 2 therefrom with its 
end being extended from cutting portion 9 into heating portion 2. 
Therefore, as shown in FIG. 4, adjusting portion 3 is fixed by mounting 18 
to adjacent heating portion 2, so that the cooling air intaked from air 
ventilating passage 11 by fan 16 is passed through the inner of heating 
portion 2 and then discharged from holes 8 to cool heating portion 2. 
Mounting 18 made by stainless steel is covered on the upper of heating 
portion 2 and adjusting portion 3. 
As shown in FIG. 5, oscillating portion 4 includes case 29 having dual 
compartments into which is divided by compartment wall 19. Upper 
compartment 20 is slightly larger than lower case 21, all sides of which 
is formed as inlet portion 22 for intaking the cooling air. Also upper 
compartment is provided with fan 23 installed properly in its inner space 
relative to the center of compartment wall 19, where the air blowing hole 
is perforated. Lower compartment 21 is provided with electrical parts of 
the oscillating source mounted therein, such as PCB, the magnatron and the 
transformer (not shown), etc. and outlet portion 22' formed at its sides 
to allow the cooling air intaked from upper compartment 20 to be 
discharged through outlet portion 22', thereby cooling oscillating portion 
4. On the other hand, heating portion 2, adjusting portion 3 and 
oscillating portion 4 are electrically connected through leading wire 24 
and connection line 25 to each other. 
Therefore, in the case that the invention is adopted to the free standing 
electronics cooker as shown in FIG. 6, each of heating portion 2 and 
oscillating portion 4 may be installed at upper and lower sides of sink 26 
using the inner space of the body with being separated from each other. In 
the case that the invention is adopted to the platform type cooker, 
heating portion 2 and oscillating portion 4 assembled, respectively, may 
be properly fixed to each other with being separated. 
As described above, the invention has the separated body corresponding to 
each of parts, so that the body may be made thin to facilitate their 
transportation and installment. 
The invention has at least one cooling means for cooling the heating 
portion and the oscillating portion, respectively, so that the cooling 
efficiency may be enhanced. 
Also, the invention can allow the user to easily be accessible to the body 
of each parts and remove the interference on the adjusting portion due to 
the high temperature and the oscillating frequency caused by the heating 
portion and/or the oscillating portion, so that the body to be repaired 
may be easily exploded and repaired as well as the operation of the 
applicance equipment may be smoothly performed.
