The filter 500 is installed in the circulation passage 200 to filter the foreign substances from the air in which the oil component is dissolved by the alcohol supplied from the alcohol supply container 400. The filter 500 is detachably attached to the alcohol supply container 400 Can be combined. The filter 500 includes a prefilter for removing foreign substances such as smoke and odors from the air when grilling meat on the grill 120 using the charcoal of the charring stand 110, May be made of various filters, may be made of a single material, or may be made of a plurality of the same or different kinds.

The operation of the ductless smokeless furnace according to the present invention will now be described.

After the alcohol supply container 400 is filled with alcohol, for example, isopropanol, the char cradle 110 is filled with the ignited char and the meat is roasted on the grill 120 at the upper end of the furnace main body 100. At this time, the air between the grill 120 and the charring table 110 is sucked through the suction port 221 of the suction passage 220 by the driving of the air blowing fan 300 and is supplied to the connecting passage 240, 240 to the space 130 between the grill 120 and the charring table 110 through the alcohol supply container 400 and the filter 500 and through the discharge port 211 of the supply passage 210.

At this time, an alcohol volatilized directly from the alcohol supply container 400 or volatilized by the diverging member 420, for example, isopropanol, dissolves the oil component contained in the air passing through the connection passage 230, The smoke and odor generated when the furnace 10 is used is re-supplied and reused by passing through the filter 500. This makes it convenient to use and reduces harmful elements to the human body, By minimizing the stickiness of the material to be filtered in the filter 500 by dissolving the components, the use period of the filter 500 can be increased.

The air supplied from the outside through the grill 120 is guided to the inlet 241 through the charring stage 110 and the air inlet 112 by the suction force of the intake passage 240 to which the wind power of the air blowing fan 300 is transmitted, And is circulated through the connection passage 230 and the supply passage 210 so that the char combustion efficiency in the charring stage 110 is increased and the rotation of the rotation plate 253 of the inflow amount adjusting section 250 The char combustion efficiency can be controlled by controlling the amount of the introduced air by the operation.

Further, the ductless smokeless furnace 10 according to the present invention minimizes installation space due to its simple structure, can reduce a cost burden, and is easy to maintain and manage.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
