Turning to

FIGS. 3 and 4

, the piston


49


accommodated in the cylinder


41


reciprocates within the cylinder


41


by the driving means


51


. More particularly, the piston

47


and the outside diffusing nozzle


43


, and a second diffusing position (B) to open the inlet port


47


and the inside diffusing nozzle


45


. As described above, the computer aroma generator


71


, as in the aroma generator


30


provided in the microwave oven, is provided with a plurality of diffusing nozzles, to diffuse food aromas or smell removers outside and inside of the computer.




As shown in

FIG. 5

, the cooking system is also provided with a controller


61


transferring a data signal supplied from the computer system


70


through the Internet


80


to the microwave oven


1


through the interface


60


, and activating the magnetron


23


based on the signal transferred to the microwave oven


1


.




The controller


61


activates the aroma generator


30


provided in the microwave oven


1


to thereby generate a food aroma or a smell remover according to the food during cooking. According to a cooking menu selected from the computer


70


, the controller


61


activates the computer aroma generator


71


, to thereby diffuse a food aroma or a smell remover to the outside of the computer


70


.




Referring to

FIG. 6

, a method for controlling a cooking system according to the present invention will be described in more detail.




As shown therein, a user first makes his or her computer system access to an Internet site supplying cooking menus to select his or her desired cooking menu (S


1


), and then the selected cooking menu is supplied from the Internet site (S


2


). The controller


61


produces a food aroma according to the selected cooking menu by appropriately mixing the aroma substances (S


3


), and diffuses the produced food aroma through the computer aroma generator


71


to the outside of the computer


70


(S


4


). At the same time, the controller


61


transfers data on the selected cooking menu to the microwave oven


1


through the interface


60


(S


5


). A cooking menu is selected from the microwave oven


1


, based on the cooking menu data transferred to the microwave oven


1


(S


6


), and the controller


61


produces a food aroma according to the selected cooking menu, by mixing the aroma substances stored in the aroma storage unit


31


(S


7


).




If the food aroma is produced from mixture of the aroma substances, the controller


61


activates the driving means


51


to move the piston


49


of the aroma diffuser


40


to the first diffusing position A. As the piston


49


is moved to the first diffusing position A, the inside diffusing nozzle


45


is closed (S


8


). If the inside diffusing nozzle


45


is closed by the piston


49


, the food aroma produced by mixture of the aroma substances is diffused toward the outside of the main body


3


through the outside diffusing nozzle


43


for a predetermined period of time (S


9


).




The controller


61


can control the outside diffusing nozzle


43


so as to allow the produced food aroma to be diffused increasingly or intermittently. The controller


61


can also control the outside diffusing nozzle


43


so as to allow the food aroma to be diffused only when the cooking menu is initially selected or when cooking for the selected cooking menu is finished.




The controller


61


activates the outside diffusing nozzle


43


to diffuse the food aroma outside and operates the magnetron


23


to cook the food in the cooking chamber (S


10


). While the magnetron


23


is in operation for cooking, the controller


61


drives the driving means


51


so as to allow the piston


49


of the aroma diffuser


40


to move the second diffusing position B and closes the outside diffusing nozzle


43


(S


11


). After the outside diffusing nozzle


43


is closed, the controller


61


activates the inside diffusing nozzle


45


to diffuse the food aroma produced according to the selected cooking menu into the cooking chamber


5


for a predetermined time (S


12


).




When it is determined that cooking is finished, the controller


61


produces a smell remover corresponding to the selected cooking menu by mixture of the aroma substances stored in the aroma storage units


31


(S


13


). The produced smell remover is diffused to the outside of the main body


3


and into the cooking chamber


5


through the outside diffusing nozzle


43


and the inside diffusing nozzle


45


(S


4


), respectively. Thus, the food aroma remaining inside the cooking chamber


5


and outside the main body


3


is removed.




For those users who visit an Internet cooking site with interest in cooking but cook no food by means of the microwave oven


1


, the computer system according to the present invention can only conduct the steps of S


1


through S


5


in

FIG. 6

, without transferring cooking data to the microwave oven. After performing S


1


through S


5


, a step of producing a smell remover, corresponding to the food aroma generated in the computer aroma generator


71


may be further comprised, to remove the remaining food aroma.




Where a user selects a cooking menu through the keyboard


15


provided in the microwave oven


1


, instead of using the Internet


80


, the steps of S


6


through S


12


in

FIG. 6

may be only conducted. After performing S


6


through S


12


, the steps of producing a smell remover, corresponding to the food aroma generated in the computer aroma generator


71


may be further comprised, to remove the remaining food aroma.




With this configuration, the user accesses a cooking-related site over the Internet


80


through the computer


70


and selects a cooking menu. If a cooking menu is selected, the selected cooking menu is displayed on the display of the computer system


70


, and at the same time, the computer aroma generator


71


is activated to diffuse a food aroma according to the selected cooking menu to the outside of the computer


70


.




When a cooking menu is selected from the computer


70


, the controller


61


transfers data on the selected cooking menu to the microwave oven


1


through the interface


60


and activates the microwave oven


1


based on the transferred cooking menu data. The controller


61


can operate the aroma generator


30


formed in the microwave oven


1


to thereby diffuse the food aroma according to the selected cooking menu to the outside of the microwave oven and the inside of the cooking chamber.




The preferred embodiment of the present invention have been described with reference to a computer system. However, the present invention may also be practiced by means of cellular phones, portable display assistants (PDAs), etc. which are accessible to the Internet.




In the above-described embodiment, the smell remover is produced by mixture of the aroma substances and diffused. However, the food aroma can be removed by providing a deodorizing filter to deodorize the remaining food aroma and a fan blowing the food aroma toward the deodorizing filter.




The diffusing nozzles


43


and/or


45


can be rotatably provided to adjust diffusing directions of the food aroma and the smell remover. Alternatively, a food aroma diffusing nozzle to diffuse the food aroma and a smell remover diffusing nozzle to diffuse a smell remover can be separately provided.




Further, an aroma to maintain the inside of a cooking chamber with a fresh air can be produced by mixing the aroma substances stored in the aroma storage unit


31


; or the aroma can be directly stored in the aroma storage unit


31


.




As described above, according to the present invention, there is provided a cooking system capable of selecting a cooking menu through a computer accessed to the Internet, supplying data on the selected cooking menu to a cooking apparatus such as a microwave oven, and generating a food aroma and a smell remover according to the selected cooking menu.




Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
