Steam drying machine
Technical Field
The invention relates to the technical field of household steam disinfection equipment, in particular to a steam dryer.
Background
At present, most of bowl and chopstick disinfection equipment used in families on the market is a disinfection cabinet, the disinfection cabinet utilizes an ultraviolet lamp to irradiate bowls and chopsticks to achieve the purpose of sterilization and disinfection, but the bowls and the chopsticks are mutually shielded, and the ultraviolet lamp light cannot irradiate all positions of the bowls and the chopsticks, so that the sterilization and disinfection effect is poor, or the bowls and the chopsticks are easily deformed and the bowls are yellowed due to overhigh temperature. Later, people use steam to sterilize and disinfect bowls and chopsticks, but the steam basically passes through a tubular steam generator or a cylindrical steam generator, and the steam generated by heating water in the tubular steam generator or the cylindrical steam generator is sprayed to the bowls and chopsticks through a steam nozzle, so that the bowls and chopsticks are comprehensively sterilized and disinfected through high-temperature steam. However, the tubular steam generator is fast in steam generation but very easy to generate scale, and the tubular steam generator is easily blocked by the scale after being used for a period of time; the drum type steam generator is not easy to be blocked by scale, but the steam generation is slow, and the steam spray head of the drum type steam generator and the steam spray head are easy to be blocked in the using process, so that the scale at the steam spray head needs to be cleaned frequently.

3 tops of wind-guiding frame are opened, 7 bottom surfaces of dish that generates heat and 3 top sealing connection of wind-guiding frame become confined air heating chamber 30, 7 bottom surfaces of dish that generates heat extend a plurality of fins 72 towards air heating chamber 30, 3 one sides of wind-guiding frame extend to 1 top surface of base through air-out passageway 31 and form hot air outlet 5, hot air outlet 5 sets up towards holding box 2 bottoms, 5 edges of hot air outlet are equipped with round arch 51, it is connected with the windscreen 50 to rotate on the arch 51, windscreen 50 covers at protruding 51 top surface, in order to shelter from hot air outlet 5, the recessed three recess 52 that forms of protruding 51 top surface, recess 52 is the inverted trapezoid groove, the recess 52 tank bottom is higher than 1 top surface of. 3 opposite sides of air guide frame pass through inlet air channel 32 and fan 35's air outlet intercommunication, be equipped with integrative lamp 33 of ozone sterilization in the inlet air channel 32, integrative lamp 33 of ozone sterilization is the inspiratory air sterilization disinfection of fan 35, when fan 35 inspiratory air heated the chamber 30 through the air, 7 bottom surfaces of heating plate also can be to air sterilization disinfection and dehumidification, the air intake of fan 35 is close to 1 diapire of base, 1 diapire of base corresponds the air intake and is equipped with air inlet grid net 13.
The protection device comprises a temperature sensor 61, a temperature controller 62 and a fusing device 63, wherein the temperature sensor 61, the temperature controller 62 and the fusing device 63 are all arranged on the bottom surface of the heating plate 7, the control circuit board 4 is arranged on the inner side wall of the base 1 outside the air heating cavity 30, the switch 40 is arranged on the side wall of the base 1, and the heating plate 7, the magnetic switch 8, the fan 35, the switch 40, the temperature sensor 61, the temperature controller 62 and the fusing device 63 are all electrically connected with the control circuit board 4. The fusing device 63 is a blown fuse.
Put into holding box 2 with bowl chopsticks, holding box 2 is whole to be placed on base 1 top surface, and on base 1 top surface in leg 11 was placed in to the stabilizer blade 21 of holding box 2, magnet 22 was placed in the magnetic switch 8 top, and magnet 22 is induced to magnetic switch 8, and magnetic switch 8 sends the signal and gives control circuit board 4, allows heating plate 7 circular telegram.
The method comprises the steps of pouring a proper amount of water into the containing box 2 (or pouring a proper amount of water into the steam generating cavity 70 in advance), pressing the switch 40, electrifying the heating plate 7 to work, heating the heating plate 7 to heat water to generate steam, enabling the steam to rise to enter the containing box 2 through the through hole, sterilizing and disinfecting bowls and chopsticks of the containing box 2 by high-temperature steam, enabling the water carried after the bowls and chopsticks are cleaned or the condensed water formed after the steam contacts the bowls and chopsticks to drip onto the base 1 through the through hole, then flowing back to the heating plate 7 to be heated into steam again, enabling the wind cover 50 to compress the hot air outlet 5 after the steam is cooled and sunk, enabling the steam to basically not escape through the hot air outlet 5, and enabling the water to be blocked by the bulges 51 and the wind cover 50 and.
Because the thermal conductivity of water is higher than that of air, when water exists on the heating plate 7, the heat of the heating plate 7 is mainly used for heating water, a small amount of heat heats the air through the fins 72, after the water on the heating plate 7 is boiled to be dry, the air is heated on both sides of the heating plate 7, and the accommodating box 2 and the bowls and chopsticks are dried through hot air. In the process, the temperature sensor 61, the temperature controller 62 and the fusing device 63 constantly monitor the temperature of the heating plate 7, when the heating plate 7 reaches a certain temperature, the temperature sensor 61 controls the fan 35 to work, the fan 35 sucks cold air, the cold air takes away heat through the bottom surface of the heating plate 7 and the fins 72, so that the temperature of the heating plate 7 is maintained in a certain range, the cold air becomes hot air after absorbing heat, the hot air enters the steam generation cavity 70 and the accommodating box 2 through the hot air outlet 5, the top surface of the base 1 and the bowls and chopsticks in the accommodating box 2 are dried, when the temperature of the heating plate 7 continues to rise, the temperature controller 62 triggers and disconnects the power supply of the heating plate 7, the temperature controller 62 fails, and the fusing device 63 disconnects the.
If the heating plate 7 heats water, the temperature is approximately between 100 and 120 degrees, after the water on the heating plate 7 is boiled to be dry, the temperature of the heating plate 7 exceeds 120 degrees, the temperature sensor 61 detects that the temperature of the heating plate 7 reaches 120 degrees, the fan 35 starts to work, the temperature of the heating plate 7 can be maintained between 120 and 150 degrees, when the air in the steam generation cavity 70 and the accommodating box 2 reaches a certain temperature, the heat dissipation effect of the fan 35 is reduced, the temperature of the heating plate 7 exceeds 160 degrees, the temperature controller 62 detects that the temperature of the heating plate 7 reaches 160 degrees and then cuts off the power supply of the heating plate 7, the heating plate 7 stops heating, after the temperature of the heating plate 7 is recovered to be normal temperature, the temperature controller 62 resets, if the temperature controller 62 fails, the temperature of the heating plate 7 exceeds 190 degrees, the fusing device 63 is directly fused.
Because thermal-insulated sealing washer 73 has blockked some heats, base 1 and holding box 2 all adopt 110 resistant plastics high temperature can, consequently, dish 7 that generates heat can not lead to base 1 and holding box 2 the condition of melting to appear, ensures user safety in utilization.
When water in the water boiling tank 71 is too much and overflows the top surface of the base 1 (the water level is lower than the surrounding wall 11), the water boiling tank 71 and the top surface of the base 1 in the surrounding wall 11 jointly form the steam generating chamber 70, the water overflowing the protrusion 51 can be discharged from the air inlet grid mesh 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, wherein the fan 35 is a centrifugal fan, the motor of the fan 35 is arranged on the upper part of the fan 35, and the water flows through the lower part of fan blades of the centrifugal fan, so that the fan 35 cannot be damaged.
