The outer peripheral edge of the top surface of the base 1 is provided with a surrounding wall 11 . The top surface of the base 1 in the surrounding wall 11 is inclined toward the steam generating chamber 70 , and a magnetic switch 8 is provided in the base 1 near the top.

The top of the air guide frame 3 is open, the bottom surface of the heating plate 7 and the top of the air guide frame 3 are sealed and connected to form a closed air heating cavity 30, and the bottom surface of the heating plate 7 extends toward the air heating cavity 30. The hot air outlet 5 is formed by extending to the top surface of the base 1 through the air outlet channel 31. The hot air outlet 5 is arranged toward the bottom of the accommodating box 2, and the edge of the hot air outlet 5 is provided with a circle of protrusions 51. The cover 50 covers the top surface of the protrusion 51 to block the hot air outlet 5 . The top surface of the protrusion 51 is concave to form three grooves 52 . The grooves 52 are inverted trapezoidal grooves. The other side of the air guide frame 3 is communicated with the air outlet of the fan 35 through the air inlet channel 32. The air inlet channel 32 is provided with an integrated ozone sterilization lamp 33. When the fresh air passes through the air heating chamber 30, the bottom surface of the heating plate 7 will also sterilize and dehumidify the air. The air inlet of the fan 35 is close to the bottom wall of the base 1, and the bottom wall of the base 1 is provided with an air inlet grid 13 corresponding to the air inlet.

The protection device includes a temperature sensor 61 , a temperature controller 62 and a fuse device 63 . The temperature sensor 61 , the temperature controller 62 and the fuse device 63 are all arranged on the bottom surface of the heating plate 7 , and the control circuit board 4 is arranged outside the air heating chamber 30 . On the inner side wall of the base 1, the switch 40 is arranged on the side wall of the base 1. The heating plate 7, the magnetic switch 8, the fan 35, the switch 40, the temperature sensor 61, the thermostat 62 and the fuse device 63 are all electrically connected to the control circuit board 4. connect. The blowing device 63 is a blowing fuse.

Put the tableware into the accommodating box 2, the accommodating box 2 is placed on the top surface of the base 1 as a whole, the legs 21 of the accommodating box 2 are placed on the top surface of the base 1 in the surrounding wall 11, and the magnet 22 is placed on the magnetic switch Above 8, the magnetic switch 8 senses the magnet 22, and the magnetic switch 8 sends a signal to the control circuit board 4 to allow the heating plate 7 to be energized.

Pour an appropriate amount of water into the accommodating box 2 (you can also pour an appropriate amount of water into the steam generating chamber 70 in advance), press the switch 40, the heating plate 7 is energized, the heating plate 7 heats water to generate steam, and the steam rises through The through hole enters the container box 2, and the high temperature steam sterilizes the tableware and chopsticks in the container box 2. The water carried by the tableware after washing or the condensed water formed after the steam contacts the tableware and chopsticks will drip onto the base 1 through the through hole, and then Return to the heating plate 7 and be heated again into steam, wherein, after the steam cools and sinks, the wind cover 50 will press the hot air outlet 5, so the steam will basically not escape through the hot air outlet 5, and the water will be affected by the protrusion 51 and the wind cover 50. Block inaccessible hot air outlet 5.

Since the thermal conductivity of water is higher than that of air, when there is water on the heating plate 7, the heat of the heating plate 7 is mainly used to heat the water, and a small amount of heat heats the air through the fins 72. After the water on the heating plate 7 is dried, the heating plate 7 7. Air is heated on both sides, and the hot air makes the accommodating box 2 and the tableware and chopsticks dry. During this process, the temperature sensor 61, the thermostat 62 and the fuse device 63 monitor the temperature of the heating plate 7 at all times. The temperature sensor 61 controls the fan 35 to work when the heating plate 7 reaches a certain temperature, and the fan 35 inhales cold air, which passes through the heating plate. 7. The bottom surface and the fins 72 take away the heat, so that the temperature of the heating plate 7 is maintained within a certain range, and the cold air becomes hot air after absorbing heat. and the accommodating box 2 tableware, when the temperature of the heating plate 7 continues to rise, the thermostat 62 triggers and disconnects the power supply of the heating plate 7, and the thermostat 62 fails, then the fuse device 63 disconnects the power supply of the heating plate 7.

For example, when the heating plate 7 heats the water, the temperature is roughly between 100-120°. After the heating plate 7 is boiled with water, the temperature of the heating plate 7 exceeds 120°. The temperature sensor 61 detects that the temperature of the heating plate 7 reaches 120°, and the fan 35 starts. During operation, the temperature of the heating plate 7 will be maintained between 120-150°. When the air in the steam generating chamber 70 and the accommodating box 2 both reach a certain temperature, the heat dissipation effect of the fan 35 will decrease, and the temperature of the heating plate 7 will exceed 160°. After the temperature controller 62 detects that the temperature of the heating plate 7 reaches 160°, the power supply of the heating plate 7 is disconnected, the heating plate 7 stops heating, and after the temperature of the heating plate 7 returns to the normal temperature, the temperature controller 62 is reset. When the temperature of the disk 7 will exceed 190°, the fuse device 63 will be blown directly, and the heating disk 7 will be powered off.

Since the heat insulation sealing ring 73 blocks some heat, both the base 1 and the accommodating box 2 can be made of plastic that can withstand a high temperature of 110°. Therefore, the heating plate 7 will not cause the base 1 and the accommodating box 2 to melt, ensuring that the user Safe to use.

When the water in the boiling water tank 71 is too much and overflows over the top surface of the base 1 (the water level is lower than the surrounding wall 11 ), the boiling water tank 71 and the top surface of the base 1 in the surrounding wall 11 together form the steam generating chamber 70 , which overflows the protrusion 51 The water will be discharged from the air inlet grid 13 through the hot air outlet 5, the air outlet channel 31, the air guide frame 3, the air inlet channel 32, and the fan 35. The fan 35 is a centrifugal fan, and the motor of the fan 35 is placed on the upper part of the fan 35. , the water flows under the centrifugal fan blades without damaging the fan 35 .
