IPC: F24C15/20
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To realize a domestic hot plate capable of preventing smoke from being diffused within a room by highly efficient smoke collection. SOLUTION: This hot plate comprises a heating means 5 arranged under a dish-like plate 4, a suction port 6 partially opened to the plate surface, a plate circumferential wall 7 having an inclination of obtuse angle with the plate surface, a blowing port 8 arranged in the upper part of the plate circumferential wall 7, an air passage 14 for connecting the suction port 6 to the blowing port 8, and a blowing means 9 and a smoke removing means 12 which are arranged within the air passage 14. Since air is discharged from the blowing port 8 to the suction port 6 provided in the center of the plate, the discharged air generates a negative pressure part in the inside space of the plate circumferential wall 7, which causes a Coanda effect of pulling the discharged air downward, so that an air flow is formed near the plate surface.  The smoke can be thus pushed away toward the suction port 6 in the center of the plate without being shifted upward against the ascending current on the plate.
