[ other embodiments ]

Ultraviolet lamp beads are further arranged in the disinfection cavity 14, and are turned on to perform ultraviolet irradiation on the surfaces of the chopsticks and the cutters, so that the chopsticks, the cutters and the chopping block are disinfected fully. When the chopsticks and the knife are in specific work, the heater is started to generate hot air, the peripheries of the chopsticks and the knife are filled with the hot air, and the surfaces of the chopsticks and the knife are dried through the hot air. Open ultraviolet lamp pearl afterwards, through the ultraviolet of shining of ultraviolet lamp pearl, keep the continuous disinfection to chopsticks, cutter to disinfect fast or completely according to the demand, ultraviolet lamp pearl sets up relatively, prevents to appear shining the dead angle, thereby carries out the ultraviolet all-round and disappears.

The heating assembly may also be provided with steam heating means for sterilizing the dishes in the chamber 14 with hot steam.

The fan 9 may be an axial flow fan or a cross flow fan. Moist air in the disinfection chamber 14 can be pumped out through a vacuum pump to keep the interior of the disinfection chamber 14 dry, so that bacteria breeding is avoided

The utility model discloses a working process or principle as follows:

when the sterilizer works, the electric control board 7 controls the PTC8 to heat and simultaneously controls the fan 9 to operate. The PTC8 heats the air in the first chamber 21, the heated air is blown into the second chamber 22 by the fan 9 and enters the disinfection chamber 14 through the air outlet 6, and the hot air dries the tableware in the chopstick cylinder 3 and the knife slot 4 in the disinfection chamber 14.

The water on the dishes in the chopstick container 3 and the knife slot 4 drops to the lining cover 26 below the sterilizing chamber 14, and a small amount of water is evaporated by the hot air in the sterilizing chamber 14. If the water is accumulated more, the water flows into the second chamber 22 of the heating assembly from the air outlet and flows out of the machine through the drainage channel 15. Because the partition plate 16 is arranged between the first chamber 21 and the second chamber 22 and the fan 9 blows, water flowing into the heating assembly cannot enter the first chamber 21, the safety of electric devices in the sterilizing machine can be ensured, and the safety and the service life of products are improved.

The heating component is provided with a temperature-resistant cover 5 and a temperature-resistant seat 10 which cover the PTC8 and the heat emitted by the PTC8 in a cavity inside, so that the heating component can insulate and insulate heat, and can well protect the lining cover 26 and the base. The heating assembly can be assembled as an assembly in advance during production, so that the production is convenient, and the replacement and maintenance are convenient.
